3 * Stop for a couple seconds after badkup router has become
4 primary router. Affected file silcd/server.c.
6 * Added silc_server_remove_servers_by_server, which is used
7 to remove servers originated from some other server. Also
8 clients of those servers can be removed too. Affected file
9 silcd/server_util.[ch].
11 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Fixed a bug in silc_string_regexify which did not add '^'
14 at the start of each string, and thus the matching was
15 not explicit. For example ban list iikone@*!*@* would
16 match also "priikone", which is wrong, it would have to be
17 *iikone@*!*@* to match also "priikone". Affected
18 file lib/silcutil/unix/silcunixutil.c.
20 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
22 * Enable all local server connections before updating client
23 caches when we've become backup router. Otherwise, signoff
24 packets may not reach the clients. Affected files are
25 silcd/server.c and silcd/server_util.[ch].
27 * Fixed a bug in version string parsing which could crash
28 the program with specially formatted version string.
29 Bug reported and patch provided by Ville Räsänen. Affected
30 file lib/silcutil/silcutil.c.
32 * Handle the disconnection immediately when DISCONNECT
33 packet is received in server. Affected file silcd/server.c.
35 * Primary router now waits a short time (10 seconds) for
36 backup router connection before accepting any other
37 connection (except local). Affected file silcd/server.c,
40 * Fixed a crash in client libary in NICK_CHANGE notify when
41 NICK_CHANGE arrived for client entry we are resolving
42 currently. Affected file lib/silcclient/client_notify.c.
44 * Call the sconn->callback completion even if error had
45 occurred. Start reconnecting always if connection to
46 primary router fails during backup router protocol.
47 Affected files silcd/server.c and server_backup.c.
49 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
51 * Added functions silc_server_send_opers and
52 silc_server_send_opers_notify to send packets stricly
53 to operators. Added macro SILC_SERVER_SEND_OPERS macro
54 to send variable argument notify to operators.
55 Affected files silcd/packet_send.[ch] and silcd/server.h.
57 * Removed UMODE rights checking with UMODE_CHANGE notify.
58 Affected file silcd/packet_receive.c.
60 * Server/router operator now receives notify when network
61 switches to backup router and when it resumes the use of
62 primary router. Affected file silcd/server.c and
63 silcd/server_backup.c.
65 * Fixed the updating of client information after backup
66 resuming protocol is over; update all except local clients
67 to the new primary router. The affected file is
70 * Added support for closing active connections in rehash
71 that were unconfigured by the user. Supports currently
72 closing server and router connections. Affected file
75 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
77 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
80 is NULL since seems that on some platforms NULL is allowed
81 and on some it's not. Fallback encoding is used instead.
82 Affected file lib/silcutil/silcstrutil.c.
84 * Fixed statistics updating for incoming server connection
85 which could cause problems when re-connecting. Affected
88 * Preliminary backup router support for standalone router
89 added. Affected files in silcd/.
91 * Mark server connections in backup router disabled before
92 and after backup protocol. Affected file is
93 silcd/server_backup.c.
95 * Added support for reconnecting to remote server connection
96 even if the protocol fails, and if the configuration wants
97 us to keep trying to connect anyway.
99 Server connection is not allowed to backup router if
100 backup router does not have connection to primary router yet.
102 Affected file is silcd/server.c.
104 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Added silc_client_udpate_server function to update changed
107 server info. Affected file lib/silcclient/idlist.[ch].
109 * Added check for server entries that are being resolved when
110 notify is received. If being resolved, handle the received
111 notify only after it's resolved so that all notifys are
112 handled in same order as received from the server.
114 Added similar resolver check to channel entries. Every
115 notify that cause resolving of any information that affects
116 channel entry marks the channel entry in waiting state.
117 After whatever resolving is over the waiters are signalled
118 and only then the notifys are handled in the same order
119 as delivered from the server.
121 Affected files are lib/silcclient/idlist.[ch], and
124 * Fixed KILLED notify handling in normal server. Affected
125 file silcd/packet_receive.c.
127 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
128 is locally connected, or was locally connected (but may
129 be detached and connection is not active). Added also
130 SILC_IS_LOCAL for checking this status. Affected files
131 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
132 silcd/server.c and silcd/server_internal.h.
134 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Don't send or handle TOPIC_SET if topic is already set and
137 is same as being set. Affected files silcd/command.c and
138 silcd/packet_receive.c.
140 * Fixed CMODE change rights checking to work correctly when
141 removing modes by operator. Affected file is

153 Affected files configure.in.pre, lib/contrib/Makefile.am.
155 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
157 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
158 to the sender of the notify too, to avoid situation where two
159 notifys are in the network at the same time going to oppsite
160 directions. Affected file silcd/packet_receice.c.
162 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
164 * Delete the client from channel even if the cilent->id is
165 NULL. It was possible that client was deleted without
166 removing from channels (theoretically at least). Affected
167 file silcd/server.c and silcd/server_util.c.
169 * Free the client data too when resuming is not successful.
170 Affected file silcd/packet_receive.c.
172 * Merged some code from c0ffee's silc-plugin. Affected files
173 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
175 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
176 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
177 to the primary router connection, the other one returns
178 TRUE if packet must be broadcasted to network.
180 * All notifys that are destined to primary router (to network)
181 are now automatically sent to backup routers even if the
182 router is standalone (and has backup router). Affected files
185 * Added --without-irssi and --without-silcd configuration
186 options for disabling the compilation of these applications.
187 Affected file configure.in.pre and prepare.

192 UTF-8 encoding and decoding. Added also new encodings
193 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
195 Added also SILC_STRING_LANGUAGE which is language and charset
196 specific encoder and decoer for those platforms that support
197 iconv(). It can convert the UTF-8 to and from the locale
198 specific character set.
200 Affected file lib/silcutil/silcstrutil.[ch].
202 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.

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

253 that the one authenticating becomes the only founder on the
254 channel. Affected file silcd/command.c.
256 * Better checking for founder mode setting when CUMODE_CHANGE
257 notify is received. Affected file silcd/packet_receive.c.
259 * Close all connections when shutting down the server by sending
260 DISCONNECT packet. Close all listeners too when shutting
261 down the server. Affected file silcd/server.c.

336 The one that authenticated will become founder and anyone
337 else is demoted. Affected file silcd/command.c.
339 * Added error printing of any error that has occurred during
340 any command in client library. Affected file is
341 irssi/src/silc/core/client_ops.c.

905 with the channel message MAC (and not only by packet MAC).
906 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
907 Affected file is lib/silccore/silcchannel.c.
909 * Fixed the SKE to save the remote version, since the
910 silc_ske_parse_version mistakenly checked wrong version,
911 after it replaced the start payload. Affected files are

1032 * Some client implementations quit network by doing first LEAVE
1033 and then immediately SIGNOFF (like Bombyx). We now do check
1034 after a short time after LEAVE notify and check whether the
1035 client is still valid after LEAVE, and if not we remove it from
1036 cache. Affected file is lib/silcclient/client_notify.c.
1038 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1069 * Fixed the Irssi SILC Client to use the silc_get_username and
1070 silc_get_real_name insted of glib routines since the glib
1071 routines only corrupt stack. Fixes the Irssi SILC to work in
1072 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1074 * Fixed the Irssi to not use g_get_home_dir since it crashes
1075 or returns garbage on cygwin and corrupts stack. Added function
1076 get_home_dir to Irssi routines. Affected files are
1077 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1079 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1081 * Made some structure optimizations. SFTP memory FS MemFSEntry
1082 entry structure. Optimized SilcTask structure. Optimized
1083 SilcPacketContext structure.
1085 Affected files lib/silcsftp/sftp_fs_memory.c,
1086 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1088 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * And yet again reverted back the config thing since Johnny
1091 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1094 * Fixed memory leaks from config object. Affected files are
1095 silcd/serverconfig.[ch].
1097 * Added support for adding new connections to the server in rehash.
1098 After rehash they take effect.
1100 Added support for changing the maximum allowed connections in
1101 rehash. The number can grow but going smaller is not supported.
1103 Added function silc_server_num_sockets_by_remote to the
1104 silcd/server_util.[ch].
1106 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1108 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1110 * Added preliminary checking during config parsing for a valid
1111 public/private key and removed further checks in the code.
1112 Affected files are silcd/serverconfig.[ch], server.c.
1114 * Moved functions silc_server_drop() and silc_server_daemonise()
1115 from server.c to silcd.c since they are stricly related to
1116 the application activity.
1118 * Reverted a small part of the automatic ref/unref since
1119 it caused a double unref in some situations. Affected
1120 files are silcd/silcd.[ch], server.c, serverconfig.c.
1122 * Added some .cvsignore files in the lib directory.
1124 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1126 * Fixed silc_net_gethostbyaddr to correctly resolve by
1127 address. Affected file lib/silcutil/silcnet.c.
1129 * Fixed the notify relaying to client. The HMAC to be used
1130 with relayed packets ws wrong and caused decryption failure
1131 at the client end. Affected file is silcd/packet_receive.c.
1133 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1135 * Created new branch silc_protocol_1_0_branch.
1137 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1139 * Changed the silc_server_config_* routines to be SilcServer
1140 independent. They are now officially application specific code
1141 and not part of generic server implementation. Affected files
1142 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1144 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1146 * Added automatic referencing of config context in the
1147 silc_server_config_alloc, and automatic unreferencing in the
1148 silc_server_config_destroy. Affected files are
1149 silcd/serverconfig.[ch], silcd/silcd.c.
1151 * Fixed the silc_log_quick handling in the logging routines.
1152 It didn't log quickly when it was TRUE. Affected file is
1153 lib/silcutil/silclog.c. Also the flush delay was set even
1154 if it was 0 in config file. Affected file is
1155 silcd/serverconfig.c.
1157 * Added support for changing key pair of the server in rehash.
1158 Affected file silcd/server.c.
1160 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1163 too early, before getting the channel entry. Affected file
1164 is silcd/packet_receive.c.
1166 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1168 * Added functions silc_server_config_[ref/unref], these are used
1169 to prevent that the config object is destroyed.
1171 No longer directly affect global variables silc_log_quick and
1172 silc_log_delay, they are first cached inside the config object
1173 and then applied with silc_server_config_setlogfiles().
1175 silc_server_config_set_defaults() is now internal to
1176 serverconfig.c, there are no reasons to show this internal stuff
1179 Affected files are silcd/serverconfig.[ch].
1181 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1182 fprintf's to stderr, since some code may be executed again after
1183 the server went into the background. Affected files are
1186 * Added rehash support. Added function silc_server_rehash() that
1187 will perform all the basic tasks of the rehashing procedure.
1189 * Added command line option `-x, --hexdump'. This will enable the
1190 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1191 The option `--hexdump' implies `--debug'.
1193 * Fixed a bad bug in the logging APIs (silcutil library) where
1194 the application would crash after calling silc_log_reset_all().
1196 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Fixed the KICKED notify handling in client library to
1199 correctly remove the channel and all entries from the
1200 channel when I was kicked. This bug crashed the client.
1202 Fixed yet another but in KICKED notify handling to remove
1203 the kicked client correctly from the channel.
1205 Affected file is lib/silcclient/client_notify.c.
1207 * Fixed a minor bug in looking up correct client entry
1208 in KICKED notify in server. Affected file is
1209 silcd/packet_receive.c.
1211 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1212 sources correctly to distribution. Fixes --with-gmp option.
1214 * Removed the manual rehashing from ID Cache, and changed it
1215 to use the SILC Hash Table's auto rehash feature. Affected
1216 file is lib/silccore/silcidcache.c.
1218 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Fixed a bug in the silc_client_nickname_format function that
1221 handles the multiple same nickname formatting. Two clients
1222 with same nickname caused problems after the first one left
1223 and rejoined. It didn't format the nickname correctly.
1224 Affected file is lib/silcclient/idlist.c.
1226 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1228 * Don't change the topic if olod topic is same as new one.
1229 Affected file is silcd/packet_receive.c.
1231 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Added cross-reference support to the SILC Documentation
1234 generator. All types across all HTML files are now cross-
1235 referenced. Affected files util/robodoc/generator.c and
1236 scripts/silcdoc/silcdoc.
1238 * Added file lib/silcutil/silctypes.h to include all the
1239 arithmetic type definitions and some macros. Removed
1240 includes/bitmove.h and moved macros to silctypes.h.
1242 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1244 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1246 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1248 * Added `type' argument to silc_id_payload_parse_id function which
1249 now returns the type of the ID to the sent pointer. Affected
1250 file is lib/silccore/silcid.[ch].
1252 * Added check for CMODE_CHANGE notify type that mode change is
1253 allowed by the sender. Affected file silcd/packet_receive.c.
1255 * Added check for CUMODE_CHANGE notify type that mode change is
1256 allowed by the sender. Affected file silcd/packet_receive.c.
1257 Added the ID type as CUMODE_CHANGE notify type as argument
1258 to the `notify' client operation. Affected files are
1259 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1261 * Added function silc_client_add_server to the client library.
1262 Added support for resolving also channel and server info when
1263 received unknown entity in notify packet. Affected files are
1264 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1266 * Added function silc_command_get_status to return the command
1267 status from the command reply's argument payload. Affected files
1268 are lib/silccore/silccommand.[ch].
1270 * Added check for KICKED notify type that the kicking is
1271 allowed by the client. Affected file silcd/packet_receive.c.
1273 * Created function silc_get_input which can be used to get input
1274 (echo on or off) from user on command line. Affected files are
1275 lib/silcutil/silcutil.[ch].
1277 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * Optimized silc_server_packet_relay_to_channel function.
1280 Added new function silc_channel_message_payload_encrypt which
1281 can be called directly if channel message payload needs to
1282 be encrypted and is already encoded (no need to call _encode
1283 function). Packet relaying is now done by router without any
1284 extra memory allocations. Affected files are
1285 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1286 silcd/packet_send.c.
1288 * Fixed the INVITE notify handling. It took wrong arguments
1289 as invite list and invite delete. Affected file is
1290 silcd/packet_receive.c.
1292 * Added check for TOPIC_SET notify type that the topic change is
1293 allowed by the client. Affected file silcd/packet_receive.c.
1295 * Added check for INVITE notify type that inviting is allowed by
1296 the client. Affected file silcd/packet_receive.c.
1298 * Changed the silc_server_client_on_channel to return the
1299 SilcChannelClientEntry as well. Moved the function
1300 silc_server_check_cmode_rights to server_util.[ch].
1301 Affected files are silcd/server_util.[ch], silcd/command.c.
1303 * Added function silc_server_check_umode_rights to check whether
1304 changing client's user mode is allowed. Added check for
1305 UMODE_CHANGE notify type that the umode change is allowed
1306 by the client. Affected files are silcd/server_util.[ch],
1307 silcd/packet_receive.c and silcd/command.c.
1309 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1312 ID length. It ignored that ID can be IPv6 based as well.
1313 Affected file lib/silccore/silcpacket.h.
1315 * Fixed the silc_id_id2str and silc_id_str2id to take the
1316 IPv6 address offset's into consideration. Affecte file is
1317 lib/silccore/silcid.c.
1319 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Fixed the internal Unix scheduler functions to check for
1322 NULL context they may receive. The affected file is
1323 lib/silcutil/unix/silcunixschedule.c.
1325 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1327 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1328 can specify different directory with --home command line
1329 parameter. Affected files irssi/src/silc/core/client_ops.c,
1332 * SILC-specific commands aren't now executed if the active server
1333 isn't of SILC-type, so there won't be problems with having
1334 IRC and SILC protocol support in same client. Affected files
1335 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1338 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Improved the signal support in SILC Schedule. Added new
1341 function silc_schedule_signal_call which is used by application
1342 to mark a signal to be called. It is now safe to perform
1343 any kind of tasks in signal callbacks since it is guaranteed
1344 that the application specified signal callback is called
1345 after the signal is over. Affected files are
1346 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1348 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1350 * Added `name' field to SilcChannelPrivateKey to represent
1351 application given name for the key. Moved also the context from
1352 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1353 Added the `name' argument also to the function
1354 silc_client_add_channel_private_key.
1356 Added function silc_client_current_channel_private_key to set the
1357 current channel private key in use.
1359 Added "change" command to KEY command which can be used to change
1360 the current channel private key. Bound the command also to
1361 alt+K (Alt+Shift+k).
1363 Also affected files lib/silcclient/client_channel.c,
1364 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1366 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Added silc_rng_get_byte_fast function in to the
1369 lib/silccrypt/silcrng.[ch].
1371 * Changed the interface of silc_packet_assemble and the
1372 silc_packet_send_prepare. If silc_packet_assmble is now
1373 called the application does not call silc_packet_send_prepare
1374 because the library will call it automatically. These
1375 interfaces now also return a reference to the outgoing buffer
1376 which includes the assembled packet, which the application can
1377 use to encrypt the packet.
1379 Affected files are lib/silccore/silcpacket.[ch],
1380 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1381 silcd/packet_send.c, server_backup.c and packet_receive.c.
1383 * Fixed a packet sending bug on very high load, where outgoing
1384 packet queue wasn't handled correctly and packets got corrupted.
1385 Affected files are lib/silcutil/*/silc*sockconn.c,
1386 lib/silcclient/client.c and silcd/server.c.
1388 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Added macro SILC_PACKET_DATALEN which can be used during
1391 packet assembling to check whether the data to be added to
1392 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1393 len is truncated until it fits it.
1395 Added checks for maximum length of channel message payload and
1396 private message payload also.
1398 Added checks for maximum packet length in server and in
1401 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1402 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1403 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1404 lib/silcclient/client_prvmsg.c.
1406 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1408 * Added silc_server_packet_queue_purge call to the
1409 silc_server_disconnect_remote to assure that all data in the
1410 queue before disconnecting is sent to the network. Affected
1411 file silcd/server.c.
1413 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1415 * Added the deleting of server's own ID cache entry to the
1416 silc_server_free function. Free also everything else that
1417 has been allocated in silc_server_init. The affected file
1420 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1422 * Added functions silc_parse_version_string, silc_version_to_num,
1423 and silc_ske_parse_version to parse SILC protocol style version
1424 strings. Affected files lib/silcutil/silcutil.[ch] and
1425 lib/silcske/silcske.[ch].
1427 * Added new configuration params: version_protocol, version_software
1428 and version_software_vendor to specify what version the remote
1429 host must at least be to be able to connect to server. The vendor
1430 string can be regex matched too. Added new function
1431 silc_server_connection_allowed to check maximum number of allowed
1432 connections, and allowed versions for incoming connections.
1433 Affected files are silcd/server.c, server_util.[ch] and
1436 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1438 * Added preliminary support for signals in scheduler. The
1439 signals we care about are now blocked always when the scheduler
1440 is locked. This way we can synchronise the use of signal with
1441 scheduler. It is guaranteed that when signal occurs the scheduler
1442 is not locked, and thus new tasks can be safely added to the
1445 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1446 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1447 Added new platform specific routines
1448 silc_schedule_internal_signals_[un]block and
1449 silc_schedule_internal_signal_[un]register.
1451 Added new functions to SILC Schedule API:
1452 silc_schedule_signal_[un]register. Each signal that application
1453 is going to use should be registered to the scheduler.
1455 Affected files are lib/silcutil/silcschedule.[ch],
1456 lib/silcutil/*/silc*schedule.c.
1458 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1460 * Check for unauthenticated client and server in the
1461 silc_server_new_client and silc_server_new_server functions.
1462 Affected file silcd/packet_receive.c.
1464 * Added function silc_string_is_ascii to check whether given
1465 string is 7-bit ASCII string. Affected files are
1466 lib/silcutil/silcutil.[ch].
1468 * Added function silc_id_is_valid_server_id into the
1469 silcd/serverid.c and added checking for valid Server ID's in
1470 silc_server_new_server. The Server ID must always be based
1471 on the server's public IP address.
1473 * Added logging of DISCONNECT packet message in the server.
1474 Affected file silcd/server.c.
1476 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1478 * Changed all library interfaces that use Global RNG to also
1479 accept SilcRng as argument. Affected files are
1480 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1481 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1482 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1483 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1484 lib/silccrypt/rsa.c.
1486 * Added function silc_pkcs_generate_key to the
1487 lib/silccrypt/silcpkcs.[ch] for applications so that they
1488 don't need to do pkcs->pkcs->init calls anymore.
1490 * Remove SilcSocketConnection from the SFTP API since it really
1491 wasn't needed there. The application has the information
1492 saved in its contexts anyway and the SFTP layer doesn't need
1493 know about it. Affected files lib/silcsft/silcsftp.h and
1494 lib/silcsftp/sftp_[server/client].c.
1496 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1497 The SilcSimContext is not SilcSim.
1499 * Fixed possible buffer overflows in silc_id_render in the
1500 lib/silcutil/silcutil.c.
1502 * On EPOC the global crypto module lists are not used at all
1503 in the crypto library. Added support for using the constant
1504 algorithm list on EPOC. Affected files are
1505 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1508 * Fixed the handling of third parameter of KICKED notify, since
1509 it was mistakenly updated to SILC Protocol 1.0 even though it
1510 is to be included in 1.1. Since it is not in 1.0 it is not
1511 mandatory, and this fix now handles it only if it is provided,
1512 and it is not error if it is not provided. Affected file
1513 lib/silcclient/client_notify.c.
1515 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1517 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1518 client. Affected file irssi/src/silc/core/client_ops.c.
1520 * Merged with Irssi 0.8.4 from irssi.org CVS.
1522 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1524 * Check for valid socket connection in client entries before
1525 sending any messages. Fixes a crash, but doesn't fix some
1526 other underlaying bug that is lurking there. Affected
1527 file silcd/packet_send.c.
1529 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1531 * $usermode, $cumode and $cumode_space expandos shouldn't do
1532 anything with non-SILC server records. Affected file
1533 irssi/src/silc/core/silc-expandos.c
1535 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1537 * Fixed the silc_net_check_[host/local]_by_sock to support
1538 IPv6 bound sockets as well. Now they can return IPv6 addresses
1539 as well. Affected file lib/silcutil/silcnet.c.
1541 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1542 Affected lib/silcutil/unix/silcunixnet.c.
1544 * Fixed ID rendering (at least on some platforms, not NetBSD)
1545 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1547 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1549 * Added silc_hash_public_key and silc_hash_public_key_compare
1550 functions to be used with SilcHashTable. They can be used to
1551 hash public keys and compare public keys in hash table. Affected
1552 file lib/silcutil/silcutil.[ch].
1554 * Added support for specifying multiple public keys for Client
1555 connection section in server configuration file. This makes it
1556 possible to accept multiple public keys from same host, or to
1557 make a section that accepts any incoming host, and have the
1558 accepted public keys listed in the section.
1560 Added functions silc_sever_[find/get]_public_key, added the
1561 support for this actually to all connection sections but only

1737 the SKE interface a bit.
1739 * Fixed padding problem in PKCS#1. The padding was not actually
1740 random since the random number generator was used incorrectly.
1741 This security bug affects only when encrypting with PKCS#1, and
1742 it is not currently used at all in SILC. SILC only use signing
1743 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1807 irssi/src/fe-text/silc.c.
1809 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1811 * Added new configuration options and blocks:
1812 keepalive_secs, reconnect_count, reconnect_interval,
1813 reconnect_interval_max, reconnect_keep_trying and

1828 the connection configuration object from the SilcServerConnection
1829 object instead of finding it during the connecting phase.
1830 Added the configuration object to SilcServerConnection struct.
1831 Affected files silcd/server_internal.h, server.c.
1833 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1835 * Add the client on channel after it was resolved at the
1836 channel message receiving, and it was not already on the
1837 channel. Affected file lib/silcclient/client_channel.c.

1859 public key is set. If not set, public key is preferred.
1860 This has effect only when being initiator (responder will try
1863 Added support for authentication with passphrase and public key
1864 at the same time. The passphrase is tried first always since
1865 it is faster to check.
1867 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1869 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1915 * Fixed the file transfer's key agreement payload to include
1916 zero port also if the hostname is NULL because it could not
1919 Call file transfer monitor callback now also if error occurs
1920 during key agreement protocol.
1922 Changed the silc_client_file_send interface to return the
1923 SilcClientFileError instead of session id. The session ID
1924 is returned into pointer provided as argument.

1965 the callback returned.
1967 Do not allow auto rehashing of hash table during the
1968 silc_hash_table_foreach operation, for same reasons as it is
1969 not allowed for SilcHashTableList. Affected files are
1970 lib/silcutil/silchashtable.[ch].

1996 * Fixed a bug in hash table tarversing. While the hash table
1997 is traversed with SilcHashTableList the table must not be
1998 rehashed. It is now guaranteed that auto rehashable tables
1999 are not rehashed while tarversing the list. Also defined that
2000 silc_hash_table_rehash must not be called while tarversing
2001 the table. Added function silc_hash_table_list_reset that must
2002 be called after the tarversing is over. The affected files are
2003 lib/silcutil/silchashtable.[ch].
2005 * Changed all hash table traversing to call the new
2006 silc_hash_table_list_reset in server and in client library.
2008 * Added function silc_client_on_channel to return the
2009 SilcChannelUser entry if the specified client entry is joined
2010 on the specified channel. This is exported to application as
2011 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2020 lists correctly. Affected file silcd/command.c.
2022 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2024 * When sending JOIN command to router for processing the
2025 sender's old command identifier was not saved back to the
2026 sender's command context, fixed now. The affected file is
2029 * Create the key in JOIN command of the router did not return
2030 the channel key, added check for this. Affected file is
2033 * Fixed a channel ID update bug in JOIN command reply. Do
2034 not directly upgrade the ID but call the function
2035 silc_idlist_replace_channel_id if the ID was changed.
2036 Affected file silcd/command_reply.c.
2038 * Fixed memory leaks from command calling if it would fail.
2039 Affected file silcd/command.c.

2070 user list for the channel again, and server won't be in
2071 desync in some rare circumstances. Affected file is
2072 silcd/packet_receive.c.
2074 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2090 the SilcClientOperation functions in their application.
2091 Updated the lib/silcclient/README as well to tell about this
2092 nice file made available.
2094 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2096 * Call silc_server_remove_from_channels when removing client
2097 entry when NO_SUCH_CLIENT_ID was received. Affected file
2098 is silcd/command_reply.c.
2100 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * Added server & router operator statistics updating. Affected
2103 file silcd/packet_receive.c and silcd/command.c.
2105 * Fixed the SERVER_SIGNOFF notify handling on normal server
2106 not to save the history information for clients. Same was
2107 fixed earlier in remove_clients_by_server function, but not
2108 here. Affected file silcd/packet_receive.c.
2110 * Raised the default connection-retry count from 4 to 7 in
2111 server. Affected file silcd/server.h.
2113 * Cancel any possible reconnect timeouts when we start the
2114 key exchange. Affected file silcd/server.c.
2116 * Do not reconnect on connection failure when SCONNECT was
2117 given. Affected files silcd/server.[ch].
2119 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2121 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2123 * Fixed the NICK command to always give the unformatted
2124 nickname to the one giving the NICK command. If unformatted
2125 nickname is cached already it will be formatted and the
2126 local entry will always get the unformatted nickname.
2127 Affected file lib/silcclient/idlist.c.
2129 * Fixed some double frees from client library commands.
2130 Affected file is lib/silcclient/command.c.
2132 * Fixed CUMODE command in server to assure that no one can
2133 change founder's mode than the founder itself, there was a
2134 little bug. Affected file silcd/command.c.
2136 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2138 * Removed the SilcClientCommandDestructor from the client
2139 libary, it is not needed anymore. Affected files are
2140 lib/silcclient/silcapi.h, command[_reply].[ch],
2141 client_notify, idlist.c.
2143 * Fixed GETKEY command to first resolve client, and then
2144 resolve the server only if the client was not found, instead
2145 of resolving both at the same time. Affected file is
2146 lib/silcclient/command.c.
2148 * Added silc_client_start_key_exchange_cb and lookup the
2149 remote hostname and IP address before starting the key
2150 exchange with server. The affected file is
2151 lib/silcclient/client.c.
2153 * The server's public key is now saved using the IP address
2154 of the server and not the servername for the filename.
2155 The hostname public key filename is checked as an fall back
2156 method if the IP address based filename is not found.
2158 Fixed the GETKEY command to save the fetched server key
2159 in correct filename.
2161 Print the remote server's hostname now when new key is
2162 received during connection process. Affected file is
2163 irssi/src/silc/core/client_ops.c.
2165 * Return always our own public key to the client if it asks
2166 for it with GETKEY command. Affected file silcd/command.c.
2168 * Removed the use_auto_addr variable from default config
2169 file since it was in wrong section. Affected file is
2172 * Fixed TOPIC_CHANGE notification to not route it when it
2173 was sent using silc_server_send_notify_to_channel function.
2174 Affected file silcd/command.c.
2176 * Fixed silc_server_send_notify_kicked to send the kicker's
2177 Client ID also, it was missing. Affected files are
2178 silcd/command.c, silcd/packet_send.[ch].
2180 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2182 * Do not save client history information in SERVER_SIGNOFF.
2183 Fixes the bug in normal server that it does not detect
2184 the client becoming valid after the server becomes back
2185 online. Affected file silcd/server_util.c.
2187 * Added `sock_error' field into the SilcSocketConnection
2188 context. When error occurs during socket operation (read
2189 or write) the error is saved. Added also new function
2190 silc_socket_get_error to return human readable socket error
2191 message. Affected files are lib/silcutil/silcsockconn.[ch],
2192 lib/silcutil/unix/silcunixsockconn.c, and
2193 lib/silcutil/win32/silcwin32sockconn.c.
2195 * The server now prints the socket error message in the
2196 signoff for client. Affected file silcd/server.c.
2198 * Fixed the `created' channel information sending from router
2199 to server in JOIN command. Checks now whether the channel
2200 really was created or not and set it according that.
2202 Fixed the JOIN command to use the client entry's current
2203 ID during the joining procedure instead of the one it sent
2204 in the command (it is checked though), since it can change
2205 between the packet processing and command processing, and
2206 would just case unnecessary pain in the client end. Affected
2207 file silcd/command.c.
2209 * Fixed a channel key payload sending to use correct channel
2210 ID when the server was forced to change the channel's ID by
2211 router. Router sent the key payload with the old Channel ID.
2212 Affected file silcd/packet_receive.c.
2214 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2216 * Call silc_server_save_channel_key only if the key payload
2217 was provided in the JOIN command's command reply. Affected
2218 file silcd/command_reply.c.
2220 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2222 * Fixed silc_mp_sizeinbase to return the value correctly with
2223 MPI. Affected file lib/silcmath/mp_mpi.c.
2225 * Fixed the stop_server signal to correctly stop the scheduler
2226 and gracefully stop the server when SIGTERM or SIGINT signals
2227 are received. Affected file silcd/silcd.c.
2229 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2231 * Simple handling of TERM and HUP signals. Also added some log
2232 flushing call around. Affected file is
2235 * Fixed small bugs in silclog.c. Now buffering output will take
2236 effect after 10 seconds since startup: This will ensure that
2237 no important startup messages are lost. Also output redirection
2238 will preserve original format ([Date] [Type] message).
2239 Affected file is lib/silcutil/silclog.c.
2241 * Added two options to the config file, in the logging section:
2242 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2243 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2245 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2247 * Do not print the warning about log files not being initialized
2248 more than once to avoid excess logging. Affected file is
2249 lib/silcutil/silclog.c.
2251 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2252 the SIM copying in make install in Makefile.am.pre.
2254 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2256 * Rewritten silclog APIs. Globally interesting changes follows:
2257 silc_log_set_files() changed to silc_log_set_file().
2258 silc_log_set_callbacks() changed to silc_log_set_callback().
2259 ROBOdoc documented silclog header file.
2260 SilcLogCb now returns bool to wether inihibit the default
2261 handler or not (to keep the old behaviour return always TRUE).
2262 The new APIs should also fix the problem of the
2263 silcd_error.log file that was written in the current directory.
2266 Log files streams will remain opened after silc_log_set_file()
2267 call, means less CPU usage notably on high traffic servers.
2268 File streams are now full buffered, and flushed to the disk
2269 every 5 minutes, lesses HD activity and CPU usage.
2270 Messages can be redirected, allowing admins to configure
2271 one single logfile for all server messages.
2272 the silc_log_quick global variable to activate fast-logging.
2273 Affected files lib/silcutil/silclog.[ch]
2275 * Changed some code to conform new silclog APIs. Affected
2276 files are doc/example_silcd.conf.in, silcd/server.c
2277 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2280 * Fixed a memory leak that could occur in some situations.
2281 Affected file silcd/serverconfig.c.
2283 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2285 * Added the silc_client_del_client to remove the client from
2286 all channels as well. Affected file lib/silcclient/idlist.c.
2288 * Fixed the client library to correctly remove the client
2289 from all channels when the client entry is being destroyed.
2290 Affected file lib/silcclient/client_notify.c, command.c.
2292 * Added auto-nicking support to the client library. If the
2293 applicatio now sets client->nickname it will be sent to the
2294 server after connecting by the library. This way for example
2295 SILCNICK (or IRCNICK) environment variables will have effect
2296 and always change the nickname automatically to whatever
2297 it is wanted. Affected file lib/silcclient/client.[ch].
2299 * Renamed silc_server_command_bad_chars to the
2300 silc_server_name_bad_chars and moved it to the
2301 silcd/server_util.[ch]. Added also new function
2302 silc_server_name_modify_bad to return nickname that
2303 includes bad characters as new nickname without those
2304 bad characters. This check and modify is now used in
2305 silc_server_new_client when the username is initially set
2306 as nickname, so it must be checked to be valid nickname.
2307 Affected file silcd/packet_receive.c.
2309 * The nickname length is now taken from the packet for real
2310 and not trusted to strlen() since it clearly can return
2311 wrong length for nickname including bad characters. This
2312 also applies to channel names. Affected file silcd/command.c.
2314 * Removed the lib/silcsilm/modules directory. Modules are now
2315 compiled into the lib/silcsim. Fixed the copying of the
2316 modules to follow symbolic links in Makefile.am.pre.
2318 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2320 * Fixed silc_string_regexify list creation. Fixes bugs with
2321 BAN and INVITE commands in server. The affected file is
2322 lib/silcutil/unix/silcunixutil.c.
2324 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Removed the command destructor entirely from the server's
2327 command and command reply routines. It is not needed, and
2328 its usage was buggy and caused crashes. Affected files are
2329 silcd/command[_reply].[ch].
2331 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Cancel protocol and NULL sock->protocol if timeout
2334 occurred during protocol. Affected file silcd/server.c.
2336 * Cancel protocol timeouts always before calling the final
2337 callback, to assure that after final callback is called
2338 no other state will be called for the protocol anymore.
2339 Affected file silcd/protocol.c.
2341 * Print error log if incoming connection configuration could
2342 not be found. Affected file silcd/server.c.
2344 * Fixed JOIN command to correctly save the founder mode
2345 to the client on normal SILC server, when the channel
2346 was created by the router. Affected file silcd/command.c.
2348 * Fixed LIST command (hopefully) to send correct reply
2349 packets. Affected file silcd/command.c.
2351 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * The silc_packet_receive_process now returns FALSE if the
2354 read data was invalid packet, and TRUE if it was ok.
2356 The server now checks that if unauthenticated connection
2357 sends data and its processing fails the server will close
2358 the connection since it could be a malicious flooder.
2360 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2362 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Make sure the warning about error opening a log file is
2365 printed only once and not everytime it fails (produces
2366 too much useless log). Affected file lib/silcutil/silclog.c.
2368 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2370 * Made the silc_server_daemonise() function more readable.
2371 Affected file silcd/server.c.
2373 * Pid file is now optional, the user may comment it out from
2374 the config file. Removed define SILC_SERVER_PID_FILE, we
2375 don't need a default any longer. Affected file
2376 configure.in.pre, lib/Makefile.am.pre.
2378 * Make some use of the pid file. The server now dies at startup
2379 if it detects a valid pid file on his path. The server would
2380 die anyway in this circumstance, because of the bind() failure.
2381 Affected file silcd/silcd.c.
2383 * No longer compiling lib/dotconf.
2385 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Fixed JOIN command parsing not to crash. Affected file
2388 lib/silcclient/command.c.
2390 * Fied the NICK_CHANGE notify to add the new client entry
2391 even it is resolved. This removes an <[unknown]> nick
2392 thingy bug in the client. Affected file is
2393 lib/silcclient/client_notify.c.
2395 * Do not try to allocate 0 bytes (efence does not like it)
2396 in lib/silccore/silccomand.c when encoding payload.
2398 * Do not take IRCNICK as nickname in Irssi SILC client since
2399 it is not possible to set nickname before hand connecting
2400 the server (TODO has an entry about adding auto-nicking
2403 * Changed the silc_server_command_pending to check whether
2404 there already exists an pending entry with the specified
2405 command, command identifier and pending callback. This is
2406 to fix IDENTIFY and WHOIS related crashes that may register
2407 multiple pending commands with same identifier. Affected
2408 file silcd/command.c.
2410 * Fixed the server to reconnect to the router even if it
2411 was already reconnecting and EOF was received. This to
2412 fix a possibility that the server wouldn't ever try to
2413 auto-reconnect to the router. Affected file silcd/server.c.
2415 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Fixed the server's password authentication to use the
2418 length of the locally saved password, and not the one
2419 sent in the packet. Affected file silcd/protocol.c.
2421 * Fixed same password authentication problem in the
2422 Authentication Payload handling routines in
2423 lib/silccore/silcauth.c.
2425 * Yet another password authentication problem fixed with
2426 channel password handling in silcd/command.c.
2428 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * If first character of string in silc_parse_userfqdn is '@'
2431 then do not parse it. Affected file is
2432 lib/silcutil/silcutil.c.
2434 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Fixed minor bug in IDENTIFY command reply sending, which
2437 caused various weird problems during JOIN when it was
2438 resolving names for users. Affected file silcd/command.c.
2440 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Fixed the IDENTIFY command reply sending to chech better valid
2443 clients. It was possible to send incomplete list of replies.
2444 Affected file silcd/command.c.
2446 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Added silc_client_command[s]_[un]register functions now to
2449 dynamically register the commands in client library. Removed
2450 the static table of commands. This allows the client library
2451 to call commands without causing the application to know about
2452 what commands library has called.
2454 Removed the INFO command reply kludge to detect when the command
2455 was called by library. Now library use its own command reply
2456 function for INFO command.
2458 Added function silc_client_command_call to call a command.
2459 Application can use it to call command, not access the structure
2462 Now all commands that are sent by the client library (not
2463 explicitly sent by application) use own command reply functions.
2465 Affected files around lib/silcclient/ and in
2466 irssi/src/silc/core/.
2468 * Fixed the WHOIS command reply sending to chech better valid
2469 clients. It was possible to send incomplete list of replies.
2471 Fixed the WHOIS and IDENTIFY to send the request to router
2472 if normal server did not do it and did not find any results.
2474 Affected file silcd/command.c.
2476 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Moved the internal data from SilcClient context into its
2479 own file, not accesible to application. Affected files
2480 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2481 and other files in client library.
2483 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Added doc/examples installation target in Makefile.am.pre.
2488 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2491 commands the found client entry will be removed from the
2492 cache, after notifying application about the error. Affected
2493 file lib/silcclient/command_reply.c.
2495 * Changed the /MSG to check for exact nickname user gave, and
2496 not let `nick' match `nick@host' if it is only one found. Now,
2497 user must type the exact nickname (like nick@host2) even if
2498 there are no more than one same nicks found. This is to avoid
2499 a possibility of sending nickname to wrong nickname since
2500 `nick' could match `nick@host'. Affected file is
2501 irssi/src/core/silc-servers.c.
2503 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Do not print "you are now server operator" or similar when
2506 giving /away command. Affected files are
2507 irssi/src/silc/core/client_ops.c, silc-servers.h.
2509 * Made the silc_server_command_pending_error_check to send
2510 the same command reply payload it received back to the
2511 original sender of the command. This way all arguments
2512 that was received by the server will be received by the
2513 client too. Affected file silcd/command.c.
2515 * Added the silc_idcache_add to return the created cache entry
2516 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2518 * Add global clients to expire if they are not on any channel.
2519 This is because normal server will never know if they signoff
2520 if they are not on any channel. The cache expiry will take
2521 case of these entries. This is done by normal servers only.
2522 The affected files are silcd/command_reply.c,
2523 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2525 * If server receives invalid ID notification for WHOIS or
2526 IDENTIFY and the ID exists in the lists, it is removed.
2527 Affected file silcd/command_reply.c.
2529 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2530 in client then client entry that it matches is searched and
2531 the nickname is printed on the screen for user. Affected
2532 file irssi/src/silc/core/client_ops.c.
2534 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Use cache entry expire time in the LIST command reply to
2537 purge old entries from the cache after the LIST command
2538 reply has been received. This way we don't have non-existent
2539 entries in the cache for too long. Affected file is
2540 silcd/command_reply.c.
2542 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * If we are normal server, and we've not resolved client info
2545 in WHOIS or IDENTIFY from router, and it is global client,
2546 we'll check whether it is on some channel. If it is not
2547 then we cannot be sure about its validity and will resolve it
2548 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2549 file silcd/command.c.
2551 * Search channel by name (if possible) rather than by ID
2552 in IDENTIFY command's command reply. Affected file is
2553 silcd/command_reply.c.
2555 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2558 Updated specs and implemented it. Affected file silcd/command.c,
2559 silcd/packet_send.c and silcd/packet_receive.c.
2561 * Implemented the <founder auth> payload handling in the JOIN
2562 command. If provided all conditions for channel joining
2563 except requirement to provide correct passphrase can be
2564 overrided by the channel founder. Updated the protocol specs.
2565 Affected file silcd/command.c.
2567 Added support for founder auth in JOIN command in client
2568 library. Fixed the parsing of the JOIN command now to support
2569 all options as they should be. The affected file is
2570 lib/silcclient/command.c.
2572 * Optimized the WHOIS and IDENTIFY commands to send the request
2573 to router only if it includes nicknames or other names. If
2574 they include only IDs then check the local cache first before
2575 routing. Affected file is silcd/command.c.
2577 * Added channels topic announcements. Affected file is
2578 silcd/packet_receive.c and silcd/server.c.
2580 * Fixed the silc_server_send_notify_topic_set to really destine
2581 the packet to channel. Affected file silcd/packet_send.c.
2583 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2584 library. Affected file lib/silcclient/client_notify.c.
2586 * Added UMODE announcements. Affected file silcd/server.c.
2588 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Memory leak fixes in:
2592 lib/silcutil/silcsockconn.c
2593 lib/silcske/silcske.c
2594 lib/silcske/groups.c
2596 lib/silccrypt/silcpkcs.c
2597 lib/silccore/silccommand.c
2598 lib/silccore/silcidcache.c
2603 * ROBOdoc documented the lib/silcske/groups.h file and a
2604 bit changed the interface for better.
2606 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2608 * Update the client entry context in the ID cache after
2609 nick change. Affected file lib/silcclient/command.c.
2610 Fixes the CUMODE command when regaining founder privileges,
2611 and a little WHOIS problem.
2613 * Fixed silc_net_gethostbyname to correctly call the
2614 inet_ntop. Affected file lib/silcutil/silcnet.c.
2616 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2618 * Added IPv6 support checking to the configure.in.pre, added
2619 also --enable-ipv6 option to override the check. Affected
2620 file configure.in.pre.
2622 * The silc_thread_create now calls the start function
2623 directly if threads support is not compiled in. Removes
2624 ugly #ifdef's from generic code. Affected files are
2625 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2627 * Added silc_net_gethostby[name/addr]_async to asynchronously
2628 resolve. Affected files are lib/silcutil/silcnet.[ch].

2639 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2640 routines. Added silc_net_is_ip[4/6]. Affected file is
2641 lib/silcutil/unix/silcunixnet.c. All routines that take
2642 address as argument now supports both IPv4 and IPv6 addresses.
2644 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2646 * Fixed LIST command reply sending in server. Affected file
2649 * Server now sends the kicker's client ID in the KICK notify
2650 to the kicked client. Affected file silcd/command.c.
2652 * The client library now parses the kickers client ID and
2653 UI displays it. Affected files lib/silcclient/client_notify.c
2654 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2656 * Made all payload parsing function prototypes consistent.
2657 They all take now const unsigned char * and uint32 pair as
2658 the payload data instead of SilcBuffer. Changes all around
2659 the source tree. Other unsigned char* -> const unsigned char*
2660 changes around the tree as well.
2662 * Optimized SFTP client and server packet sending not to
2663 allocate new buffer for each packet but to recycle the
2664 first allocated buffer. Affected files are
2665 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2667 * Optimized the SFTP client to use SilcList instead of
2668 SilcDList for requests, because it is faster. Affected file
2669 is lib/silcsftp/sftp_client.c.
2671 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2672 into lib/silccore/silcid.[ch].
2674 Renamed silcpayload.[ch] into silcargument.[ch].
2676 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * If client entry is deleted with active key agreement
2679 session, abort the session.
2681 The silc_client_abort_key_agreement now calls the completion
2682 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2684 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2687 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Don't use __restrict in older GCC's. Affected file is
2690 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2692 * silc_net_localhost now attempts to reverse lookup the
2693 IP/hostname. Affected file lib/silcutil/silcnet.c.
2695 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2696 command. It can be used to gain founder privileges at
2697 the same time when joining the channel.
2699 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2700 kicker's client ID as well. Updated protocol specs.
2702 Defined that the server must send SILC_COMMAND_IDENTIFY
2703 command reply with error status to client who sent
2704 private message with invalid client ID.
2706 Updated the protocol specification.
2708 * Added silc_server_send_command_reply to send any
2709 command reply. Affected file silcd/packet_send.[ch].
2711 * Added silc_id_payload_encode_data to encode ID payload
2712 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2714 * The server now send IDENTIFY command reply with error
2715 status if client ID in private message is invalid. Affected
2716 file silcd/packet_receive.c.
2718 * Save the server key file with server's IP address in
2719 the filename instead of hostname. The affected file is
2720 irssi/src/silc/core/client_ops.c.
2722 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2727 * Added libtool support for compiling shared objects in
2728 lib/silcsim. Affected file configure.in.pre and
2729 lib/silcsim/Makefile.am. Original patch by cras.
2731 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Pid file configuration, and server's config file fixes
2734 patch by toma. Updated CREDITS file.
2736 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Fixed silc_client_channel_message to not try to decrypt
2739 the message twice if it resolved the destination client
2740 information. This could cause of dropping one channel
2741 message. Affected file lib/silcclient/client_channel.c.
2743 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2746 lib/silcclient/client.c. This function is used when the SILC
2747 Client is run under some other scheduler, or event loop or
2748 main loop. On GUI applications, for example this may be
2749 desired to used to run the client under the GUI application's
2750 main loop. Typically the GUI application would register an
2751 idle task that calls this function multiple times in a second
2752 to quickly process the SILC specific data.
2754 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2756 * Fixed silc_server_drop() for dropping the supplementary
2757 groups as well, this could cause a security hole on some
2760 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2765 * Write PID file after dropping privileges. Added -F option
2766 to run server on foreground. A patch by debolaz.
2767 Affected files silcd/server.c, silcd/silcd.c.
2769 * Fixed MOTD to return the MOTD file server name. Affected
2770 file silcd/command.c.
2772 * Added INFO command reply handling to the Irssi SILC Client.
2773 Affected file irssi/src/silc/core/client_ops.c.
2775 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Fixed the silc_idcache_list_* routines to really support
2778 the dynamic list. Fixes a crash. Affected file is
2779 lib/silccore/silcidcache.c.
2781 * Fixed the LIST command reply to really call LIST command's
2782 pending callbacks. Affected file silcd/command_reply.c.
2784 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Update conn->local_entry->nickname after giving NICK
2787 command. Affected file lib/silcclient/command.c.
2789 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2791 * Added the [pid] option to the silcd configuration file
2793 Affected files: serverconfig.[ch] and silcd.c
2795 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Save fingerprint in WHOIS command reply in server.
2798 Affected file silcd/command_reply.c.
2800 * Fixed NICK commands pending callback registration.
2801 Affected file lib/silcclient/command.c.
2803 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Use ++server->cmd_ident when sending commands in server,
2806 instead of random number. Affected file silcd/command.c.
2808 * Fixed GETKEY command reply to call actually GETKEY pending
2809 command callbacks. Affected file silcd/command_reply.c.
2811 * A bit stricter check for nicknames. Check for same nickname
2812 in NICK command also. Affected file silcd/command.c.
2814 * Do not call INFO command everytime client ID changes, only
2815 during first connecting. Affected file lib/silcclient/client.c.
2817 * Set the new nickname only after successful command reply for
2818 NICK command is returned by server. Affected file
2819 lib/silcclient/command.c.
2821 * Remove nicknames from nicklist during server_signoff notify.
2822 Should fix /NAMES bit more. The affected file is
2823 irssi/src/silc/core/silc-channels.c.
2825 * Added `fingerprint' field to the SilcIDListData in the
2826 silcd/idlist.h to hold the fingerprint of the client's
2829 Send the fingerprint of the client's public key in WHOIS
2832 Affected files silcd/command.c, and silcd/idlist.[ch].
2834 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2835 create fingerprint from given data.
2837 * Show the fingerprint of the client's public key in WHOIS.
2838 Affected files irssi/src/module-formats.[ch] and
2839 irssi/src/silc/core/client_ops.c.
2841 * Format the multiple same nicknames also during JOIN and
2842 NICK_CHANGE notifys. Affected file is
2843 lib/silcclient/client_notify.c.
2845 * Do not print error on screen for invalid private message
2846 payload since it can come if someone is sending private
2847 messages with wrong key. Affected file
2848 lib/silccore/silcprivate.c.
2850 * Fixed multiple concurrent /PING crash. Affected file
2851 lib/silcclient/command.c.
2853 * Changed the wrong ID encoding. All IP addresses must be
2854 in MSB first order in encoded format. They were encoded
2855 wrong and was in LSB format. Affected files are
2856 silcd/serverid.c, lib/silcutil/silcutil.c.
2858 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2860 * Call the `connect' client operation through the scheduler
2861 in case of error. Affected file lib/silcclient/client.c.
2863 * Call the `failure' client operation even if the error
2864 occurred locally during a protocol. Affected file is
2865 lib/silcclient/protocol.c.
2867 * Added support of sending LIST command to router from normal
2868 server. This way normal server can get list of all channels
2869 in the network too. Fixed the channel list sending in the
2870 server too. Affected files are silcd/command.c, and
2871 silcd/command_reply.[ch].
2873 * Added silc_server_update_channels_by_server and
2874 silc_server_remove_channels_by_server. They are used during
2875 disconnection of primary router and in backup router protocol.
2876 Affected file silcd/server_util.[ch], silcd/server.c and
2877 silcd/server_backup.c.
2879 * Fixed channel adding to global list in IDENTIFY command
2880 reply in server. Affected file silcd/command_reply.c.
2882 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * If the incoming packet type is REKEY or REKEY_DONE process
2885 that packet always synchronously. Fixes yet another MAC
2886 failed error on slow (dialup) connections. Affected file
2887 lib/silcclient/client.c and silcd/server.c.
2889 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * Call check_version SKE callback for initiator too. Affected
2892 file lib/silcske/silcske.c.
2894 * Implemented fix for security hole found in the SKE that was
2895 fixed in the specification few days back; the initiator's
2896 public key is now added to the HASH value computation.
2897 Added backwards support for the old way of doing it too, for
2898 old clients and old servers. Affected file is
2899 lib/silcske/silcske.c.
2901 * Enabled mutual authentication by default in SKE. If initiator
2902 is not providing mutual authentication the responder will
2903 force it. This will provide the proof of posession of the
2904 private key for responder. The affected files are
2905 lib/silcclient/protocol.c and silcd/protocol.c.
2907 * Do not cache anymore the server's public key during SKE.
2908 We do mutual authentication so the proof of posession of
2909 private key is done, and if the server is authenticated in
2910 conn auth protocol with public key we must have the public
2911 key already. Affected file silcd/protocol.c.
2913 * Added new global debug variable: silc_debug_hexdump. If
2914 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2915 file lib/silcutil/silclog.[ch].
2917 * Fixed compilation warning due to char * -> const char *.
2918 Affected files lib/silcutil/silcnet.h, and
2919 lib/silccore/silcauth.[ch].
2921 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Fixed CMODE command when new channel key was created. If
2924 the creation failed the old key was removed. Next time giving
2925 same command would crash the server since the old key was
2926 freed already. Affected file silcd/command.c.
2928 * Fixed the silc_server_announce_get_channels to not crash
2929 on reconnect. Affected file silcd/server.c.
2931 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Added silc_log_set_debug_string function to set a regex
2934 string to match for debug output. Only the function names,
2935 or filenames matching the given debug string is actually
2936 printed. This way it is possible to filter out those debug
2937 strings that user is not interested in.
2939 Fixed a bug in silc_string_regexify.
2941 Affected files lib/silcutil/silclog.[ch], and
2942 lib/silcutil/unix/silcunixutil.c.
2944 * Changed the -d options in both server and Irssi SILC client
2945 to take the debug string as argument. Affected files
2946 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2948 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Added silc_hash_babbleprint to create a Bubble Babble
2951 Encoded fingerprint. The encoding is developed by Antti
2952 Huima (draft-huima-babble-01.txt), and it creates human
2953 readable strings out of binary data. Affected file
2954 lib/silccrypt/silchash.[ch].
2956 * Print the babble print now in addition of fingerprint as well
2957 in Irssi SILC client. Affected files are
2958 irssi/src/fe-common/silc/module-formats.[ch],
2959 irssi/src/fe-common/silc/core/client_ops.c.
2961 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Fixed a security problem found in SKE. The initiator's
2964 public key too is now added to the HASH hash value creation
2965 which is signed by the responder to create the SIGN value.
2966 This will prevent anyone in the middle to lie to the responder
2967 about the initiator's public key. If this is done now, the
2968 man in the middle will get caught. Updated the protocol
2971 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Better installation directory handling. Configure module
2974 paths and other paths automatically to example_silc* files
2975 in doc/. A patch by toma.
2977 * Fixed compiler warning from MPI library, and from SILC RNG.
2980 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2981 It can be configured with ./configure. A patch by toma.
2983 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Find correct make to use in prepare-clean. A patch by
2986 toma. Affected file prepare-clean.
2988 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2990 * Added irssi variables use_auto_addr, auto_bind_ip,
2991 auto_bind_port and auto_public_ip.
2993 * Changed the interface for silc_client_send_key_agreement
2994 in lib/silcclient/silcapi.h
2998 irssi/src/silc/core/silc-core.c
3000 lib/silcclient/silcapi.h
3001 irssi/src/silc/core/silc-channels.c
3002 lib/silcclient/client_keyagr.c
3005 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Added silc_pkcs_public_key_compare to compare two
3008 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3010 * Check that the client who set the founder mode on the
3011 channel is the same client that is giving the founder
3012 mode to itself. It is done by comparing the saved public
3013 key (it is saved even in the authentication is passphrase).
3014 Affected file silcd/command.c.
3016 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Do not process packet for disconnected socket connection.
3019 Affected file lib/silccore/silcpacket.c.
3021 * Process the DISCONNECT packet through scheduler in the
3022 client library. Affected file lib/silcclient/client.c.
3024 * Fixed the silc_client_packet_parse to not to increase
3025 the packet sequence number if the conn->sock and the
3026 current socket connection is not same. This can happen
3027 for example during key agreement when the conn includes
3028 multiple socket connections (listeners). Affected file
3029 lib/silcclient/client.c.
3031 * The sender of the file transfer request now provides also
3032 the pointer (listener) for the key exchange protocol. If
3033 the listener cannot be created then it sends empty key
3034 agreement and lets the receiver provide the listener.
3036 Added `local_ip' and `local_port' arguments to the
3037 silc_client_file_send. If they are provided they are used,
3038 if not then it will attempt to find local IP address, if
3039 not found or bind fails then the remote client will provide
3042 Affected files are lib/silcclient/client_ftp.c and
3043 lib/silcclient/silcapi.h.
3045 * Extended the FILE SEND command to support defining the
3046 local IP and port for key exchange listener. They are
3047 optional. Affected file irssi/src/silc/core/silc-servers.c.
3049 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Defined to WHOIS command reply the sending of fingerprint
3052 of the client's public key (if the proof of posession of the
3053 corresponding private key is verified by the server).
3054 Updated to the protocol specification.
3056 * Added support of receiving the client's public key's
3057 fingerprint in command reply in client library. Affected
3058 file is lib/silcclient/command_reply.c, and
3059 lib/silcclient/idlist.[ch].
3061 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Do not send over 128 chars long nickname to the server
3064 in NICK command. Affected file lib/silcclient/command.c.
3066 * Do not send over 256 chars long channel names to the server
3067 in JOIN command. Affected file lib/silcclient/command.c.
3069 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3071 * Assure that silc_server_close_connection cannot be called
3072 twice for same socket context. Affected file is
3075 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Send error message to application if opening file for
3078 writing during file transfer fails. Affected file is
3079 lib/silcclient/client_ftp.c.
3081 Remove all file transfer sessions for a client that we're
3082 removing from ID cache.
3084 Affected file is lib/silcclient/client_ftp.c.
3086 * Fixed silc_net_addr2bin to return correct address. Affected
3087 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3089 * Fixed file transfer session removing on signoff notify.
3090 Affected file irssi/src/silc/core/silc-servers.c.
3092 * Added the SilcClientFileError to be returned in the monitor
3093 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3094 Affected file lib/silcclient/silcapi.h.
3096 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Fixed a crash in silc_client_ftp_free_sessions and
3099 silc_client_ftp_session_free_client. Affected file
3100 lib/silcclient/client_ftp.c.
3102 * Added `disabled' field in the SilcChannelEntry in the server
3103 to indicate if the server entry is disabled. Affected file
3104 silcd/idlist.h, silcd/command[_reply].c.
3106 * SILC server adds now /var/run/silcd.pid everytime it is
3107 started. Affected file silcd/silcd.c.
3109 * Added silc_server_packet_send_clients to send a packet to
3110 the provided table of client entries. Affected file
3111 silcd/packet_send.[ch].
3113 * Fixed a crash in client resolving in client_prvmsg.c in
3114 client library. Affected file lib/silcclient/client_prvmsg.c.
3116 * Do not actually remove the client directly from ID cache
3117 during SERVER_SIGNOFF, but invalidate it. This way we
3118 preserve the WHOWAS info for the client. Affected file
3119 silcd/server_util.c.
3121 * Fixed SERVER_SIGNOFF notify handling in the server. The
3122 server is now able to process incoming SERVER_SIGNOFF notify
3123 for a server that it doesn't even know about. It will remove
3124 the clients provided in the notify. Affected file
3125 silcd/packet_receive.c.
3127 * Check for partial packet in data queue after every packet that
3128 was found from the queue. Return and wait for more data if
3129 there is partial data in queue. Affected file is
3130 lib/silccore/silcpacket.c.
3132 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Added SilcClietFileError enum to indicate error in
3135 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3136 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3137 Affected files lib/silcclient/silcapi.h and
3138 lib/silcclient/client_ftp.c.
3140 * Check that newsize in silc_buffer_realloc is larger than
3141 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3143 * Added better monitor of file transfers. It now monitors
3144 key agreement protocol during the file transfer too. Added
3145 error reporting too. Affected files
3146 irssi/src/silc/core/silc-servers.c,
3147 irssi/src/fe-common/silc/module-formats.[ch].
3149 * Wrote a help file for FILE command.
3151 * Added silc_rng_global_get_byte_fast to get not-so-secure
3152 random data as fast as possible. Random data is read from
3153 /dev/urandom if available and from the SILC RNG if not
3154 available. It is used in padding generation. Affected file
3155 lib/silccrypt/silcrng.[ch].
3157 * All packets in client library are now processed synchronously.
3158 Optimized packet processing a lot. Affected file
3159 lib/silcclient/client.c.

3162 now in server, to optimize packet processing. Affected file
3165 * Include files are installed now only in Toolkit distribution
3166 if make install is given. Affected files: all Makefile.am's.
3168 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Assure that silc_client_notify_by_server_resolve does not
3171 resolve the client information multiple times. If it cannot
3172 be found by the first it cannot be found at all. Affected
3173 file lib/silcclient/client_notify.c.
3175 * Fixed WHOWAS command reply calling. Affected file
3176 lib/silcclient/command_reply.c.
3178 * Removed all references to silc_idlist_get_client from the
3179 Irssi SILC client since that call is internal call used by
3180 the library. The Irssi SILC client will use now client
3181 retrieval functions found in silcapi.h.
3183 * Fixed a bug in resolving nickname info before sending
3184 private message. It used freed memory. Affected file
3185 irssi/src/silc/core/silc-servers.c.
3187 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Assure my_channels statistics cannot go negative in server.
3190 Affected files silcd/server.c, silcd/server_util.c.
3192 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3206 * Added silc_net_localip to return local host's IP address.
3207 Affected file lib/silcutil/silcnet.[ch].
3209 * If key exchange or rekey protocol is active for a connection
3210 parse all packets syncronously since there might be packets
3211 in packet queue that we are not able to process without first
3212 processing packets before them. Affected file silcd/server,
3213 lib/silcclient/client.c.
3215 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3216 whether library should continue processing the packet.
3217 Affected file lib/silccore/silcpacket.h.

3263 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3264 is incomplete and is being resolved, it won't be resolved
3267 Make sure also that USERS command reply does not resolve
3268 twice information. Affected file is
3269 lib/silcclient/command_reply.c.
3271 Make sure that silc_client_get_clients_by_list does not
3272 resolve twice same information.
3274 * Check for valid client->id in the silc_server_free_client_data.
3275 Affected file silcd/server.c.
3277 * Fixed /GETKEY nick@server not to crash if the server entry
3278 is not found. Affected file lib/silcclient/command.c.
3280 * Fixed the silc_server_check_cmode_rights to check the
3281 requested modes correctly. Affected file silcd/command.c.

3286 Affected file silcd/command.c.
3288 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Call the silc_server_udpate_servers_by_server in the
3291 primary router that comes back online in the backup resuming
3292 protocol. Otherwise it routes packets wrong. Affected file
3293 silcd/server_util.[ch], silcd/server_backup.c.
3295 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3298 lib/silcutil/silcbuffmt.[ch].
3300 * Redefined the SILC packet header to include the padding
3301 length. Affected file lib/silccore/silcpacket.[ch].
3303 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3304 length for maximum padding up to 128 bytes). Affected
3305 file lib/silccore/silcpacket.h.
3307 * Removed all backwards support for old 0.5.x MAC thingies.
3308 The SILC packet header change makes it impossible to be
3309 backwards compatible.
3311 * Send the ENDING packet with timeout in the backup resuming
3312 protocol. This is to assure that all routers has connected
3313 to the primary router. Affected file silcd/server_backup.c.
3315 * Changed the RNG to take the first IV from random data. It
3316 used to take it from zero actually. Changed the RNG also
3317 to use /dev/urandom during session. /dev/random is used
3318 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3320 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Changed the SILC packet header to have the first two bytes
3323 (the packet length) encrypted. Affected files aroung the
3324 code tree, lib/silccore/silcpacket.[ch]. Removed the
3325 SilcPacketCheckDecrypt callback. It is not needed anymore
3326 since the silc_packet_receive_process will determine now
3327 whether the packet is normal or special.
3329 * Implemented the unidirectional MAC keys. Affected files
3330 lib/silcske/silcske.c, silcd/protocol.c and
3331 lib/silcclient/protocol.c.
3333 * Implemented the packet sequence number to the MAC computation.
3334 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3335 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3336 lib/silcclient/protocol.c.
3338 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Allow backup router to announce servers. All servers
3341 announced by backup router are added to the global list
3342 automatically. Update hte server's socket to our primary
3343 router also when backup router announces a server.
3344 Affected file silcd/packet_receive.c.
3346 * Do not update the client->router in the function
3347 silc_server_udpate_clients_by_server if the client is on
3348 global list. We might fail to find any specific server
3349 for locally connected clients and local cell clients. They
3350 should still use the `from' and not `to' as client->router.
3351 This fixes backup router resuming protocol. Affected file
3352 silcd/server_util.c.
3354 * Decrease channel statistics count only if the channel
3355 deletion worked. Affected files are silcd/server.c and
3356 silcd/server_util.c.
3358 * Added silc_server_update_servers_by_server to update origin
3359 of all server entries. Used during backup router protocol.
3360 Affected files silcd/server_util.[ch], silcd/server.c. and
3361 silcd/backup_router.c.
3363 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3364 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3365 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3366 lib/silccrypt/silchmac.c.
3368 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Assure that router cannot reroute the same channel message
3371 to the sender. Affected file silcd/packet_receive.c.
3373 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Made better checks that the channel message is not sent
3376 to the router it came from. Affected file is
3377 silcd/packet_send.c. Fixed memory leak too.
3379 * Announce informations for incoming router connection, but
3380 only after checking if it is replaced by backup router.
3381 Affected file silcd/packet_receive.c.
3383 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Fixed the backup resuming protocol to work in multiple
3386 router environment. Affected file silcd/server_backup.c.
3388 * Route packet only to one router in the function
3389 silc_server_packet_send_to_channel. Affected file is
3390 silcd/packet_send.c.
3392 * Fixed silc_server_send_notify_dest to set the broadcast
3393 flag. Fixed the silc_server_send_notify_topic to actually
3394 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3395 Affected file silcd/packet_send.c.
3397 * Changed the SFTP Filesystem interface. Changed the
3398 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3399 the filesystem operation function. The SilcSFTPFilesystem
3400 is now a context that is allocated by all filesystem allocation
3401 functions and it already includes the operations structure
3402 and filesystem specific context. It is given as argument
3403 now to the silc_sftp_server_start. This made the interface
3404 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3405 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3407 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Changed the backup router adding and getting interfaces
3410 in the server. The router that will be replaced by the
3411 specified backup router is now sent as argument. Affected
3412 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3415 * Added silc_net_addr2bin_ne to return the binary form of
3416 the IP address in network byte order. Affected files
3417 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3419 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Check for existing server ID in silc_server_new_server
3422 and in silc_server_connect_to_router_final and remove the
3423 old entry if it exists. Affected file silcd/packet_receive.c,
3426 * Send the channel message always to only one router, either
3427 in upstream or downstream. Affected file is
3428 silcd/packet_send.c.
3430 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Wrote the definition of the backup resuming protocol to the
3433 protocol specification.
3435 * Removed one redundant channel key generation from normal
3436 server during joining procedure. Removed one redundant
3437 channel key sending from server to router during joining
3438 procedure. Affected file silcd/command.c.
3440 * Made minor bugfixes to the backup router resuming protocol.
3441 Affected file silcd/server_backup.c, server.c.

3446 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3449 * Implemented the backup resuming protocol that is used to
3450 resume the primary router position in the cell after the
3451 primary router comes back online. Affected files
3452 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3453 and silcd/server_util.[ch].
3455 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3457 * Sleep two (2) seconds after sending QUIT command to server.
3458 Affected file lib/silcclient/command.c.
3460 * Assure that if outgoing data buffer is pending do not force
3461 send any data. Affected file silcd/packet_send.c.
3463 * Assure that if outgoing data buffer is pending do not force
3464 send any data. Affected file lib/silcclient/client.c.
3466 * Implemented the backup router support when the primary router
3467 goes down. The servers and routers can now use the backup
3468 router as new primary router without loosing connectivity.
3470 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3473 in the server to indicate disabled entry. All data read
3474 from the connection will be ignored and no data is sent
3475 for entry that is disabled. Affected files are
3476 silcd/idlist.h, silcd/server.c.
3478 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Created SFTP client and server test programs in the
3481 lib/silcsftp/tests directory.
3483 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3485 * Implemented memory filesystem (virtual filesystem) for
3486 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3489 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Implemented the SFTP (SSH File Transfer Protocol) to the
3492 lib/silcsftp. It includes SFTP client and SFTP server
3495 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Moved lib/silccore/silcprotocol.[ch] to the
3498 lib/silcutil library.
3500 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3501 take variable argument list pointer as argument. Affected
3502 file lib/silcutil/silcbuffmt.[ch].
3504 * Added silc_buffer_set function that is used to set data
3505 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3506 Affected file lib/silcutil/silcbuffer.h.
3508 * Changed various routines in the core library to use the new
3509 silc_buffer_set instead of allocating new buffer only for
3512 * Added 64-bit value formatting and unformatting support to the
3513 silc_buffer_[un]format routines. Affected file is
3514 lib/silcutil/silcbuffmt.[ch].
3516 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3517 to includes/bitmove.h.
3519 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Fixed channel user mode saving in client library. Affected
3522 file lib/silcclient/command[_reply].c.
3524 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3526 * Defined the file transfer to the SILC Protocol. Added
3527 new packet type SILC_PACKET_FTP and defined File Transfer
3528 Payload. The mandatory file transfer protocol is SFTP
3529 (SSH File Transfer Protocol). Affected file in addition
3530 of the internet draft is lib/silccore/silcpacket.h.
3532 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3533 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3534 is used as part of backup router protocol when the primary
3535 router of the cell is back online and wishes to resume
3536 the position as primary router.
3538 * Redefined the MAC generation keys in the protocol. The
3539 same key is not used anymore in both direction. Both
3540 direction will now use different keys for sending and
3541 receiving. This fixes a potential security flaw. This
3542 change causes incompatibilities in the protocol.
3544 * Redefined also the MAC computation from the packet.
3545 An packet sequence number is now added to the MAC
3546 computation. This prevents possible replay attacks against
3547 the protocol. This change too causes incompatibilities
3550 Added `sequence' field to the SilcPacketContext to hold
3551 the current sequence number for the packet.
3553 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Added `created' field to the SilcIDListData in the file
3556 silcd/idlist.h to indicate the time when the entry was
3559 * Added `created' field to the SilcChannelEntry too. Affected
3560 file silcd/idlist.h.
3562 * Added `creation_time' aguments to all the announcement functions
3563 in the server. If it is provided then only the entries that
3564 was created after the provided time frame are actually
3565 announced. Affected file silcd/server.[ch].
3567 * The protocol says that the Channel ID's IP address must be
3568 based on the router's IP address. Added check for this in
3569 the silc_server_new_channel when processing incoming New Channel
3570 Payload. Affected file silcd/packet_receive.c.
3572 * Print out the correct version with --version in SILC client.
3573 Affected file irssi/src/silc/core/silc-core.c.
3575 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Fixed WHOWAS command to check for completnes of the client
3578 entry always, not just when the command is coming from client.
3579 Affected file silcd/command.c.
3581 * Added new function silc_server_packet_queue_purge to purge the
3582 outgoing data queue to the network. After the function returns
3583 it is guaranteed that the outgoing packet queue is empty.
3584 Affected file silcd/packet_send.[ch].
3586 * Purge the outgoing packet queue in the rekey protocol's final
3587 callback to assure that all rekey packets go to the network
3588 before quitting the protocol. Affected file silcd/server.c.
3590 * Added silc_client_packet_queue_parse as similar function as
3591 in server to the client library. The affected file is
3592 lib/silcclient/client.c.
3594 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Splitted silcd/server.c and created silcd/server_util.[ch]
3597 for utility functions.
3599 * Added new socket flag SILC_SF_DISABLED to indicate that the
3600 connection is open but nothing can be sent to or received from
3601 the connection. Affected file lib/silcutil/silsockconn.[ch].
3602 The checking for disabled socket is checked in the low level
3603 silc_socket_write and silc_socket_read functions.
3605 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Allow only nicknames and channel names that fits into the
3608 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3610 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * When processing JOIN command reply in server check that if
3613 the channel exists in our global list we'll move it the local
3614 list. Affected file silcd/command_reply.c.
3616 * Fixed the check whether client is joined on the channel already
3617 in JOIN command. Affected file lib/silcclient/command.c.
3619 * Fixed the JOIN command reply to check whether the channel
3620 already exists. Affected file lib/silcclient/command_reply.c.
3622 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3624 * Added silc_ske_status_string to map the SKE error numbers
3625 to readable strings. The affected files are
3626 lib/silcske/silcske[_status].[ch].
3628 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Do not show the private channels on the WHOIS channel list
3631 as it is not allowed by the protocol. The affected file is
3634 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Assure that the packet length digged from the actual packet
3637 is something sensible in the silc_packet_decrypt_rest_special
3638 in lib/silccrypt/silcpacket.c.
3640 * Free and NULL the allocated pointer in silc_hmac_alloc if
3641 the HMAC allocation fails. The affected file is
3642 lib/silccrypt/silchmac.c.
3644 * Print the selected security properties to the log files in
3645 the server. Affected file silcd/protocol.c.
3647 * Add SKE's reference counter even if calling the completion
3648 callback manually. Otherwise it goes negative, although it
3649 does not cause any problems. The affected file is
3650 lib/silcske/silcske.c.
3652 * Remove the client entry with short timeout after giving the
3653 KILL command. Affected file lib/silcclient/command.c.
3655 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3656 case all found clients are already disconnected (WHOWAS would
3657 found them) in the server. Affected file silcd/command.c.
3659 * Update the last_receive (time of last data received) to be
3660 updated only when received private or channel message so that
3661 the idle time showed in WHOIS makes more sense.
3663 * Added boolean field `valid' in to the SilcClientEntry in the
3664 client library to indicate whether the entry is valid or not.
3665 This fixes the nickname change bug on channel when changing
3666 the nickname to be same than the old (like nick to Nick) the
3667 nickname formatter doesn't set the new nick anymore to Nick@host.
3668 Affected file lib/silcclient/idlist.[ch].
3670 * Now actually fixed the nickname changing on disconnection.
3671 Added new function silc_change_nick to the Irssi SILC Client.
3672 Affected file irssi/src/silc/core/client_ops.c,
3673 irssi/src/silc/core/silc-nicklist.[ch].
3675 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Check that the public key exists in the GETKEY command before
3678 trying to encode it. Affected file silcd/command.c.
3680 * Print some notifications on received public keys with GETKEY
3681 command in the Irssi SILC Client. Affected files are
3682 irssi/src/fe-common/silc/module-formats.[ch],
3683 irssi/src/silc/core/client_ops.c.
3685 * Use IDENTIFY command to resolve the server information in the
3686 GETKEY command instead of INFO command. Affected file
3687 lib/silcclient/command.c.
3689 * All command reply functions in the client library now calls
3690 the pending command reply callbacks even if an error has
3691 occurred. The server has done this a long time and now it was
3692 time to move the client library to this as well. Now all
3693 errors can be delivered back to the pending command reply
3694 callbacks if necessary. Affected files are
3695 lib/silcclient/command[_reply].[ch].
3697 * Change the nickname on disconnection back to the username
3698 because in reconnect the server will enforce it to it anyway.
3699 Affected file irssi/src/silc/core/silc-servers.c.
3701 * Fixed a config file parsing bug in the Irssi SILC client.
3702 Affected file irssi/src/silc/core/clientconfig.c.
3704 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * When printing the channel mode on JOIN, verify that the
3707 channel key and channel's HMAC are valid. Affected file
3708 irssi/src/silc/core/client_ops.c.
3710 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3713 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3714 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3716 * Removed channel key rekey task deleting from the function
3717 silc_server_save_channel_key. Affected file silcd/server.c.
3718 Added explicit timeout task context instead that is used to
3719 delete the task if we are registering a new task before the
3720 new task has elapsed.
3722 * When channel key rekey occurs the client library now saves
3723 the old channel key for a short period of time (10 seconds) and
3724 is able to use it in case some is still sending channel
3725 messages encrypted with the old key after the rekey. Affected
3726 file lib/silcclient/[idlist.h|client_channel.c].
3728 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Added check to the silc_server_new_id_real to not accept
3731 new ID if it is the sender's own ID. Affected file is
3732 silcd/packet_receive.c.
3734 * Assure that we do not announce ourself or the one we've
3735 sending our announcements when we're router and are announcing
3736 servers to our primary router. Affected file silcd/server.c.
3738 * Fixed silc_server_command_identify_check_client to assemble
3739 correct WHOIS packet. It send corrupted WHOIS packet and
3740 caused problem with router to router connections. Affected
3741 file silcd/command.c.
3743 Fixed also silc_server_command_whois_check the same way
3744 as for the IDENTIFY command.
3746 * Added new SilcIDListStatus to the server in the SilcIDListData
3747 structure. The status now includes the current status of
3748 the entry (like registered, resolved etc.). Affected file
3749 silcd/idlist.[ch]. Defined a bunch of different status types
3750 as well. This replaced the old boolean registered field as well.
3752 Added resolve_cmd_ident field to the SilcClientEntry structure
3753 too so that if the entry is for example being resolved so
3754 another command may attach to the same pending command reply
3755 without requiring to resolve the same entry again. This concept
3756 should optimize the WHOIS and the IDENTIFY resolving under
3757 heavy load by taking away unnecessary resolving for entries
3758 that are being resolved already.
3760 Added support for adding multiple pending commands for one
3761 command idenfier. Affected file silcd/command[_reply].[ch].
3763 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3764 before deleting the data. Otherwise the hash table will have
3765 freed data in comparison functions. Affected file is
3766 silcd/command_reply.c.
3768 * Fixed silc_idlist_replace_client_id to add the new entry to
3769 the cache with NULL nickname. Otherwise there will be invalid
3770 memory as the nickname after the nickname is freed. Affected
3771 file silcd/packet_receive.c.
3773 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3774 saved into wrong slots because the previous number of entries
3775 was not taken into account. Affected file silcd/idlist.c.
3776 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3778 * If we are router and we receive JOIN notify to a channel that
3779 does not have any users then notified client is marked as the
3780 channel founder, as it is it. The affected file is
3781 silcd/packet_receive.c
3783 * Added to the extended hash table API's table_del_*ext functions
3784 the destructor as argument too, so that the caller can decide
3785 which destructor to use or whether to use destructor at all.
3786 Affected file lib/silcutil/silchashtable.[ch].
3788 * Fixed ID Cache purging. It actually deleted the entries from
3789 the hash table after the data was freed. The hash table ended
3790 up comparing freed memory. The affected file is
3791 lib/silccore/silcidcache.c.
3793 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Fixed Irssi SILC client's KILL command's HELP syntax.
3797 * The USERS command now resolves the detailed user information
3798 if the userinfo field is missing. Affected file is
3799 lib/silcclient/command_reply.c.
3801 * Do not print error in silc_file_read if the read file does
3802 not exist. Just silently return NULL. Affected file is
3803 lib/silcutil/silcutil.c.
3805 * Fixed the silc_log_output to not wine about NULL filename
3806 and to not create some bogus " " filename. Affected file is
3807 lib/silcutil/silclog.c.
3809 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Fixed various printing bugs on the user interface in the
3812 Irssi SILC Client. Minor changes that were forgotten from
3815 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Fixed the configure.in.pre and the compilation and distribution
3818 environment to support the new autoconf 2.52. That version is
3819 now required to compile the CVS trunk.
3821 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3824 to generally parse user@fqdn format strings. Affected file
3825 lib/silcutil/silcutil.c.
3827 * Added nickname_format and nickname_force_format fields to the
3828 SilcClientParams structure. The first one defines the format
3829 for the nicknames that the library will enforce if the receives
3830 multiple same nicknames. The second one is boolean value and
3831 can be used to force the library to always enforce the format
3832 to the nicknames regardles whether there are multiple nicknames
3833 or not. This configurable formatting was employed to flexibly
3834 support accessing multiple nicknames from the user interface.
3835 The userinterface can now set the nicknames to what ever format
3836 they prefer. Affected file lib/silcclient/silcapi.h.
3838 Added function silc_client_nickname_format to the file
3839 lib/silcclient/idlist.c. It performs the nickname formatting.
3841 Added new field `hostname´ to the SilcClientEntry context.
3842 It holds the hostname of the client. Affected file is
3843 lib/silcclient/idlist.h.
3845 * Irssi SILC Client sets the nicknames in nick@hostn format.
3846 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3847 irssi/src/silc/core/silc-core.c.
3849 The WHOIS printing now also shows both the real nickname and
3850 the formatted nickname so that user knows how to access the
3851 user if there are multiple same nicknames cached. Affected
3852 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3853 printing formatting too to take the hostname now as a separate
3854 argument. The Affected file is
3855 irssi/src/fe-common/silc/modules-formats.[ch].
3857 * Changed the silc_client_get_clients_local to accept the formatted
3858 nickname as argument. It accepts the real nickname too but the
3859 formatted nickname can be used to find the true entry from
3860 multiple entries. Affected file lib/silcclient/silcapi.h and
3861 lib/silcclient/idlist.c.
3863 * Added nickname_format_parse field to the SilcClientParams.
3864 It is a callback function provided by the application to parse
3865 the nickname out of the formatted nickname string. The library
3866 calls it to get the nickname from the formatted string. Since
3867 the application generally knows better the format of the nickname
3868 string it parses it instead of the library, even though library
3869 encodes the formatted string. If the callback function is not
3870 provided then the library will use the string as is. The
3871 affected file is lib/silcclient/silcapi.h.
3873 * All the nickname strings passed to the client library in
3874 commands are now expected to be formatted nickname strings.
3875 If the command does not support the formatted nickname string
3876 it will assume that the sent string is the actual nickname.
3877 Affected file lib/silcclient/command.c.
3879 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Added public key authentication support to OPER and SILCOPER
3882 commands in the client library. Affected file is
3883 lib/silcclient/command.c.
3885 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * Changed the get_auth_methdod client operation to be asynchronous.
3888 It can be async if the application resolves the authentication
3889 method from the server during the negotiation. Added new
3890 SilcGetAuthMeth completion callback that the application will
3891 call after resolving the authentication method.
3893 Added function silc_client_request_authentication_method that
3894 the application can use to resolve the authentication method
3895 from the server. Added also SilcConnectionAuthRequest callback
3896 that the library will call after the server has replied. The
3897 application can call this function if it does not know the
3898 current authentication method.
3900 Affected files are lib/silcclient/client.c and
3901 lib/silcclient/silcapi.h.
3903 * The Irssi SILC client now automatically resolves the authentication
3904 method incase any configuration information is not present (and
3905 currently there never is). The affected file is
3906 irssi/src/silc/core/client_ops.c.
3908 * Fixed public key authentication from the client library.
3909 Affected file lib/silcclient/protocol.c. Changed also the
3910 protocol specification about the public key authentication in
3911 the connection authentication protocol. The actual data to be
3912 signed is now computed with a hash function before signing.
3914 * Fixed the public key authentication from the server as well.
3915 Affected file silcd/protocol.c.
3917 * Removed the mlock()'s from the memory allocation routines.
3918 Affected file lib/silcutil/silcmemory.c. The ./configure does
3919 not check anymore for the mlock(). Affected file is
3922 * Fixed USERS command in server to allow the execution of the
3923 command for private and secret channels if the client sending
3924 the command is on the channel. Affected file silcd/command.c.
3926 * Fixed silc_client_get_clients_local to return the clients
3927 count correctly. It could return wrong value. Affected file
3928 lib/silcclient/idlist.c.
3930 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3932 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3933 types. The assembler optimizations seemed not to like 64-bit
3934 data types. The assmebler optimizations thus are now enabled
3935 also for BSD systems as opposed to only enable them for Linux.
3937 * Do not check for threads at all on BSD systems. Affected
3938 file configure.in.pre.
3940 * Removed -n and -h options from the Irssi SILC Client since
3941 they are not used in silc.
3943 * Fixed the prime generation to assure that the first digit
3944 of the generated random number is not zero since our conversion
3945 routines does not like number strings that starts with zero
3946 digit. If zero digit is seen the random number is regenerated.
3947 This caused some corrupted RSA keys when the zero first digit
3948 was met. Affected file lib/silcmath/silcprimegen.c.
3950 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Fixed WIN32 configuration in the ./configure script.
3953 Fixed to include xti.h on environments that has it.
3954 Patches by Carsten Ilchmann and andrew.
3956 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Changed the silc_id_create_client_id to be collision
3959 resistant. It is now assured that there cannot be created
3960 two same client ID's. I suspect that some weird bugs in
3961 the server were actually caused by duplicate Client IDs.
3962 Affected file silcd/serverid.[ch]. A router receiving
3963 new ID now also assures and informs the sending server
3964 if the ID caused collision.
3966 * Changed the silc_id_create_channel_id to also assure that
3967 there are no collisions.
3969 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3971 * Statement about ignoring the Mutual Authentication flag when
3972 performing rekey with PFS was a bit misleading. It is ignored
3973 if it was set in the initial negotiation, it cannot be even
3974 set in the rekey. Fixed in the ke-auth draft. Started the
3975 new versions of the protocol drafts in the doc/.
3977 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Fixed a bug in silc_client_command_identify_save when saving
3980 new channel information. The channel name was no duplicated
3981 and caused crash on exit. Affected file is
3982 lib/silcclient/command_reply.c.
3984 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Fixed the getkey command handling in the server. Send just
3987 empty OK reply to the sender if the key could not be fetched
3988 (but everything else was ok, like the key just was not available).
3989 Changed the public key parameter to optional in the protocol
3990 specs so that empty OK reply can be sent. Affected file
3993 Added a message to Irssi SILC client to tell to user if the
3994 server did not return a public key.
3996 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Fixed a channel key regeneration bug. It registered new
3999 timeout tasks exponentially until all system resources were
4000 used. Affected file silcd/server.c.
4002 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Added the SILC Document generator to the scripts/silcdoc.
4005 It can be used to generate the Toolkit Reference Manual out
4006 of the source tree. Internally it will also use the RoboDoc
4007 generator now imported in util/robodoc.
4009 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Added couple of return's in rekey protocol if error orccurred
4012 during the protocol. The execution must be terminated.
4013 Affected file silcd/protocol.c. Also, terminate the protocol
4014 always with timeout.
4016 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4018 * The client's Client ID was created initally from the wrong
4019 nickname (it could have been in format nick@host) in the
4020 silc_server_new_client. Affected file silcd/packet_receive.c
4022 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4024 * Added some SILC_LOG_ERROR's to various error conditions
4025 if client could not be added to ID cache. Affected files
4026 silcd/packet_receive.c and silcd/server.c.
4028 * When client's sock->user_data is freed, NULL also the
4029 client->router and client->connection pointers. Added check
4030 for these pointers being NULL to various places around the
4031 code. Affected file silcd/server.c.
4033 * Added client->data.registered == TRUE checks to various
4034 places around the code to assure that unregistered client's
4035 are not handled when it is not allowed. Affected file
4038 * Added `bool registered' fields to all
4039 silc_idlist_[server|client]_get_* routines to indicate whether
4040 the fetched client needs to be registered or not. Affected
4041 file silcd/idlist.[ch].
4043 * Add your own entry as registered to the ID cache in the
4044 server. Affected file server.c.
4046 * Fixed a bug in silc_server_new_server. The SilcServer was
4047 set as the new server's context instead of SilcServerEntry.
4048 This naturally caused some weird bugs.
4050 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Do not delete the channel rekey task when adding it
4053 for in silc_server_create_channel_key.
4055 * Changed the silc_server_create_channel_key to return
4056 TRUE or FALSE to indicate the success of the channel key
4059 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Fixed MSVC++ project files and added missing files to
4062 Makefiles under win32/.
4064 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4066 * Do not add TCP_NODELAY flag if the operating system
4067 does not have it defined. Affected files are
4068 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4070 * Fixed buffer overflow from Irssi SILC Client. Affected
4071 file irssi/src/fe-common/core/themes.c.
4073 * Fixed double free in client library in the file
4074 lib/silcclient/client.c when disconnecting from server.
4076 * Applied double free patch from cras to Irssi SILC client.
4077 Affected files irssi/src/core/[modules/expandos].c
4079 * Fixed the disconnection handling to Irssi SILC Client.
4080 The application must call silc_client_close_connection
4081 in ops->connect client operation in case of failure of
4082 the connection. Affected file is
4083 irssi/src/silc/core/client_ops.c.
4085 * Do not set sock->protocol to NULL in the function
4086 silc_client_close_connection after executing the protocol's
4087 final callback since the sock might not be valid anymore.
4088 Affected file lib/silcclient/client.c.
4090 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Do not enable SILC_THREADS if the linking with libpthread
4093 did not happen. Affected file configure.in.pre.
4095 * Added notion to protocol specification that server must
4096 verify the sent authentication payload with CMODE when
4097 setting the channel founder key. Implemented it to the
4098 server. Affected file silcd/command.c.
4100 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4102 * Added _EXTRA_DIST SILC distribution variable to the
4103 distributions file. It is used to conditionally add extra
4104 files or directories to the specific distribution. Affected
4105 files ./prepare, Makefile.am.pre and distributions.
4107 Removed the `_' from the start of the distribution names.
4110 * Added README.WIN32 for instructions to compile the Toolkit
4113 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4115 * Fixed a double free in disconnection in the server. Affected
4116 file is silcd/server.c.
4118 * Fixed the lib/silcske/groups.c to work now also with GMP
4119 MP library. The string conversion did not work when using
4120 specific base and the base is indicated in the string as well.
4122 * Created win32/ directory which now includes MSVC++ specific
4123 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4124 It will appear only in the toolkit distribution
4126 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4128 * Changed the key material distribution function in case when
4129 the hash output is too short. The data is now concatenated
4130 a bit differently than it used to. Made the change to the
4131 SKE protocol specification.
4133 * Added better GMP detection to configure.in.pre. A patch
4136 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4138 * Fixed a minor bug in SKE that might cause some problem on
4139 some platforms. Affected file lib/silcske/silcske.c.
4141 * Added the cookie checking for initiator in the SKE. It checks
4142 that the responder returns the sent cookie unmodified. The
4143 affected file is lib/silcske/silcske.c. Added new SKE
4144 error type INVALID_COOKIE that can be sent during the
4145 negotiation. Fixed some memory leaks as well.
4147 * Added the "invalid cookie" error message to Irssi SILC client's
4150 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Added `task_max' field to the SilcClientParams to indicate
4153 the maximum tasks the scheduler can handle. If set to zero,
4154 default values are used. Affected file lib/silcclient/silcapi.h.
4156 * Fixed memory leaks in silc_client_close_connection. Affected
4157 file lib/silcclient/client.c.
4159 * Added silc_client_del_client_entry to client library to free
4160 all memory of given client entry. Affected file is
4161 lib/silcclient/idlist.[ch].
4163 * Added new functions silc_client_del_channel and
4164 silc_client_del_server to delete channel and server entries.
4165 Affected file lib/silcclient/[silcapi.h/idlist.c].
4167 * Removed silc_client_del_client_by_id from silcapi.h.
4169 * Fixed the INFO command to return the server's own info
4170 correctly when querying by Server ID. Affected file is
4173 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Removed the non-blocking settings in WIN32 code in the
4176 silc_sock_[read/write] and added SleepEx instead. Affected
4177 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4178 of input data is now checked with FIONREAD and ioctlsocket.
4180 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Call silc_schedule_task_del_by_context in the
4183 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4184 Affected file lib/silccore/silcprotocol.c.
4186 * Call silc_protocol_cancel for active protocols in the
4187 silc_server_close_connection if the funtion
4188 silc_server_free_sock_user_data has not been called.
4189 Affected file silcd/server.c.
4191 * Generic tasks cannot be deleted using the del_by_fd
4192 task deleting function since generic tasks does not match
4193 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4195 * Added a notion to SILCOPER help file that the SILCOPER works
4196 only on router server, not on normal server.
4198 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4200 * Added for WIN32 support for the new scheduler as well.
4201 Affected file lib/silcutil/win32/silcwin32schedule.c.
4203 * Fixed the SHA1 implementation to work on various platforms.
4205 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4208 API. It is part of the scheduler now. Everything else is
4209 as previously but some functions has changed their names.
4210 Checkout the lib/silcutil/silcschedule.h for the interface.
4211 Updated all applications to use the new interface. Affected
4212 files are lib/silcutil/silcschedule.[ch].
4214 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4216 * Found a bug in the SKE implementation. The HASH value,
4217 specified by the protocol, was not computed correctly. The
4218 public key of the responder was not added to the computation
4219 even though it is mandatory. Affected file lib/silcske/silcske.c.
4220 This unfortunately causes incompatibilities with older
4221 clients and servers.
4223 * Added WIN32 specific network init and uninit functions:
4224 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4225 the Winsock2. Affected file lib/silcutil/silcnet.h and
4226 lib/silcutil/win32/silcwin32net.c.
4228 * Set the socket always to nonblocking mode on WIN32 after
4229 reading data or writing data. Affected file is
4230 lib/silcutil/win32/silcwin32sockconn.c.
4232 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Fixed various compilation problems under WIN32. Affected
4235 files lib/silcutil/win32/silcwin32thread.c and
4236 lib/silcutil/win32/silcwin32schedule.c.
4238 * Removed all _internal.h #includes from public header
4239 files. Internal headers must never be included from
4242 Removed also the lib/silcske/payload_internal.h file.
4244 * All include files that may be needed (public and some others
4245 included by the public headers) by application developers are
4246 now copied to the ./includes directory. It does not copy any
4247 internal headers. Affected file Makefile.defines.pre and all
4248 Makefile.am's under lib/ and subdirs.
4250 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4252 * Do not change the ~/.silc directory's permissions automatically.
4253 Affected file irssi/src/silc/core/clientutil.c.
4255 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4257 * Do not cancel the protocol in silc_server_close_connection
4258 it might cause recursion. Now cancelled in the function
4259 silc_server_free_sock_user_data. Affected file silcd/server.c.
4261 * Fixed the silc_server_remove_clients_by_server to regenerate
4262 the channel keys correctly finally. Added also new function
4263 silc_server_remove_clients_channels to actually do it.
4264 Affected file silcd/server.c.
4266 * Fixed the silc_server_new_channel to not crash by giving
4267 wrong router to the new channel. Affected file is
4268 silcd/packet_receive.c.
4270 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4272 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4273 which is given as argument to the silc_client_alloc now.
4274 It can be used to configure the client and set various parameters
4275 that affect the function of the client.
4277 * The USERS command in server did not check whether the channel
4278 is private or secret. Affected file silcd/command.c.
4280 * Added new argument to the USERS command in protocol specification.
4281 The USERS command now can take the channel name as argument
4282 as well. Added support for this in client and server and
4283 updated the protocol specs.
4285 * Completed the GETKEY command in client. It can be now used
4286 to fetch also servers public key not only some clients.
4287 Affected files lib/silcclient/command[_reply].c.
4289 * Added silc_client_get_server to return server entry by the
4290 server name. Affected files lib/silcclient/silcapi.h and
4293 * Redefined the IDENTIFY command in protocol specification to be
4294 more generic. It now can be used to query information about
4295 any entity in the SILC Network, including clients, servers and
4296 channels. The query may be based either the entity's name
4297 or the ID. Added support for this in both client and server.
4299 Affected files silcd/command.c and lib/silcclient/command.c
4300 and command_reply.c.
4302 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4303 the _from_client and _from_server functions. Affected file
4306 * Added silc_client_get_channel_by_id_resolve to the file
4307 lib/silcclient/silcapi.h to resolve channel information by
4308 its ID. Added also silc_client_get_channel_by_id that
4309 does not resolve it from the server.
4311 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4313 * Added SilcServerEntry context into the client library
4314 to represent one server. The INFO command now allocates
4315 these to save the resolved server info. For now on the
4316 client library will also keep information about servers,
4317 connected and resolved with INFO.
4319 The INFO command now allocates the SilcServerEntry context
4320 and saves the server info there. The COMMAND_REPLY in
4321 the INFO now returns the parameters to application in
4322 same order as defined in the protocol specification.
4324 The entries are cached in the client->server_cache.
4326 * The INFO command is now issued after received the Client ID
4327 from the server. Affected file lib/silcclient/client.c.
4329 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4330 to the application as the mode changer might be server.
4331 It is guaranteed that NULL is not returned anymore to the
4332 application. Affected file lib/silcclient/client_notify.c.
4334 The ID Type is now also passed to the application so that
4335 it can check whether the returned entry is SilcClientEntry
4338 Added new function silc_client_get_server_by_id to return
4339 the server entry by ID. Affected files are the
4340 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4342 * Do not create the channel in the Irssi SILC Client when issuing
4343 the JOIN command but when received the sucessful JOIN command
4344 reply. Otherwise the channel might get created even though we
4345 could not join it. The Affected file is
4346 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4348 * Fixed a channel joining bug in router. The router must also
4349 check the channel modes, invite and ban lists etc. when serving
4350 the JOIN command sent by normal server. Affected file is
4351 silcd/command.c. The router now resolves the client's
4352 information from the server who sent the JOIN command if it
4353 does not know it, and processes the JOIN command only after
4356 * Changed the SilcCommandCb to take new argument; void *context2.
4357 Affected file lib/silccore/silccommand.h
4359 The second argument in the command callbacks in the server now
4360 includes the SilcServerCommandReplyContext if the command was
4361 called as pending command callback from the command reply.
4362 Otherwise it is NULL. When called as pending the status of the
4363 command reply will be checked and if it was erronous the
4364 error will be sent to the original sender of the command.
4365 This way the client always receives the error messages even
4366 though the server was actually the one who received the error
4367 when it resent the command to router, for example. Affected
4368 files silcd/command[_reply].[ch].
4370 * Fixed sending WHOWAS command's error message to client if
4371 the requested client could not be found. It was missing.
4374 * Changed the CMODE and CUMODE commands reply arguments in the
4375 protocol specification. The Channel ID is now sent in both
4376 of the commands to identify the channel. Implemented this
4377 new feature to the client and server. Affected files
4378 lib/silcclient/command_reply.c and silcd/command.c.
4380 * Made better checks for invite and ban lists in the JOIN
4381 command in server. Affected file silcd/command.c.
4383 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4385 * The server now performs the incoming host IP/DNS lookup
4386 using the silc_socket_host_lookup and thus does not block
4387 the server anymore. Affected file silcd/server.c.
4389 * Completed the multi-thread support for SILC Scheduler in
4390 the lib/silcutil/silcschedule.c.
4392 * Fixed the configure.in.pre to detect the pthread correctly
4395 * Fixed a deadlock in silc_task_queue_wakeup in the file
4396 lib/silcutil/silctask.c.
4398 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Added new function silc_schedule_wakeup that is used in
4401 multi-threaded environment to wakeup the main thread's
4402 schduler. It needs to be used when a thread adds a new task
4403 or removes a task from task queues. After waking up, the
4404 scheduler will detect the task queue changes. If threads
4405 support is not compiled in this function has no effect.
4406 Implemented the wakeup mechanism to both Unix and WIN32
4407 systems. Affected files are lib/silcutil/silcschedule.[ch],
4408 lib/silcutil/unix/silcunixschedule.c and the
4409 lib/silcutil/win32/silcwin32schedule.c.
4411 * Added new function silc_task_queue_wakeup to wakeup the
4412 scheduler by the specified task queue. Affected file
4413 lib/silcutil/silctask.[ch].
4415 * The silc_socket_host_lookup_start now wakes up the scheduler
4416 after adding the timeout task. Affected file is
4417 lib/silcutil/silcsockconn.c.
4419 * The silc_socket_host_lookup is synchronous now if the threads
4420 support is not compiled in. However, the callback is still
4421 called asyncronously through the scheduler, anyway. Affected
4422 file lib/silcutil/silcsockconn.c.
4424 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4426 * Added new function silc_socket_host_lookup to perform
4427 asynchronous IP and FQDN lookups for the socket connection.
4428 Affected files lib/silcutil/silcsockconn.[ch].
4430 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4432 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4433 that may or may not compile the mutex support in.
4435 Changed the silc_mutex_alloc interface. It allocates the
4436 mutex now to the sent pointer and returns TRUE or FALSE.
4438 Affected file lib/silcutil/silcmutex.h.
4440 * Wrote the SILC Task Queue interface to support multi-threads.
4441 Affected file lib/silcutil/silctask.[ch].
4443 * Wrote the SILC Scheduler to support multi-threads. Affected
4444 file lib/silcutil/silcschedule.c.
4446 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4448 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4449 in lib/silcutil/win32/.
4451 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4453 * Defined SILC Mutex API and SILC Thread API and implemented
4454 them for Unix. Affected files are
4455 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4456 lib/silcutil/unix/silcunixmutex.c and
4457 lib/silcutil/unix/silcunixthread.c.
4459 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4461 * Fixed the silc_server_remove_clients_by_server's channel
4462 key re-generation. The hash table handling was incorrect
4463 and would not work with many channels. Affected file is
4466 * Fixed some memory leaks around the server code.
4468 * Rewrote the silc_server_get_users_on_channel to support IPv6
4469 based Client ID's. Affected file silcd/server.c.
4471 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4472 specification. However, a separate document must be written
4473 to define the detailed signing procedure and the payload
4474 associated with the flag. Defined the flag to the
4475 lib/silccore/silcchannel.h as well.
4477 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Changed the dynamic tables to static size tables in the
4480 lib/silccrypt/silchmac.c.
4482 * Removed GCC dependencies from the code. A patch by cras.
4484 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4486 * Do not show the error "Error receiving packet bla bla"
4487 in server if it really was not an error (-2 means that reading
4488 is pending). Affected file silcd/server.c.
4490 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4492 * Fixed a possible crash in silc_server_remove_clients_by_server
4493 in silcd/server.c. Fixed there also some memory leaks.
4495 * Fixed the silc_idlist_replace_client_id. It could replace
4496 wrong key in the hash table. Affected file silcd/idlist.c.
4498 * Do not check whether there are global users on the channel
4499 if the channel->global_users is FALSE. Affected functions
4500 silc_server_remove_from_one_channel and
4501 silc_server_remove_from_channels in silcd/server.c. Also,
4502 do not check if the removed client is local as we can be
4503 sure that global client was not removed from the channel
4504 and checking for global users is not needed.
4506 * The silc_server_remove_clients_by_server now re-generates
4507 the channel keys correctly for those channels that had
4508 clients removed from them. Affected file silcd/server.c.
4510 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * Found the reason of random crashes in the server. We weren't
4513 ignoring the SIGPIPE signal (which can be sent in write())
4514 and it crashed the server. Affected file silcd/silcd.c.
4516 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4518 * Assure that sock->user_data is not NULL in the function
4519 silc_server_packet_send in silcd/packet_send.c.
4521 * Disconnect the remote connection if it could not be added
4522 to any ID lists in the server. The affected file is
4525 * Check in silc_server_packet_send[_real/dest] that the
4526 socket is not disconnecting and ignore the data if it is.
4527 Affected file silcd/packet_send.c.
4529 * Define inline to __inline on native WIN32 compilation.
4530 Affected file includes/silcwin32.h.
4532 * Added some explicit type casts for inline code since MSVC
4533 require them. Affected files lib/silcutil/silcbuffer.h,
4534 lib/trq/silcdlist.h and lib/trq/silclist.h.
4536 * Print warning in log files from now on if the packet
4537 decryption fails. Affected file silcd/server.c.
4539 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4541 * Changed the `say' client operation's interface to accept
4542 new `type' argument to indicate the type of the message sent
4543 by the library. The application may filter the library's
4544 messages according the type. The affected file is the
4545 lib/silcclient/silcapi.h.
4547 * Added two new functions to lib/silcclient/silcapi.h:
4548 silc_client_del_client and silc_client_del_client_by_id.
4549 Affected file lib/silcclient/idlist.c.
4551 * Moved the clientincludes.h from includes/ to silc/ and
4552 serverincludes.h from includes/ to silcd/.
4554 * The modes for the CMODE and CUMODE are now passed as
4555 uint32 for application with COMMAND_REPLY. The affected
4556 file is lib/silcclient/command_reply.c.
4558 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4560 * /WHOIS without arguments shows client's own information.
4561 Affected file lib/silcclient/command.c.
4563 * Changed PING to not accept any arguments. The specs
4564 says that client can ping only the connected server so
4565 requiring an argument is not needed. Affected file is
4566 lib/silcclient/command.c.
4568 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4570 * Fixed a fatal bug in private message sending and reception
4571 encryption and decryption when using private message keys.
4572 The implementation was incorrect and did not follow the
4573 specification. It causd that some of the message were
4574 lost since it did not use the sending and receiving keys
4575 as the protocol suggests. This has been fixed and will cause
4576 incompatibilities with older clients when sending private
4577 message encrypted with private message keys. Affected files
4578 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4579 and various other in Irssi SILC Client.
4581 Added `responder' boolean argument to the functions
4582 silc_client_add_private_message_key[_ske] to indicate when
4583 the key is added as responder or initiator of the key
4586 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4588 * Removed the silc_ske_check_version function and created
4589 a SilcSKECheckVersion callback. Added also a function
4590 silc_ske_set_callbacks that is now used to set all SKE
4591 callbacks. The callback functions are not given to
4592 the SKE functions anymore, but this function is used to
4595 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4597 * Added `silc_version' argument to the silc_client_alloc
4598 to define the version of the application for the library.
4599 The library will use the version string to compare it
4600 against the remote host's (usually a server) version
4601 string. Affected file lib/silcclient/silcapi.h
4603 * Added the KE protocol context to Key Agreement context
4604 in client library so that we can abort the SKE if it
4605 is in process when we get timeout. Affected file is
4606 lib/silcclient/client_keyagr.c.
4608 * Do not resolve the client ID forever if it returns in the
4609 first time that such client does not exist. This was done
4610 for example with private message. Affected file is
4611 lib/silcclient/client_prvmsg.c.
4613 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4615 * Do not add regex.h for WIN32. The affected file
4616 includes/silcincludes.h.
4618 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4619 not work yet 100%. It generates the DLL's automatically
4620 when compiling with --with-win32 under cygwin.
4622 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4624 * lib/contrib/regex.c is not compiled on WIN32.
4626 * Added silc_net_get_socket_opt function to the
4627 lib/silcutil/silcnet.h.
4629 * Added includes/silcwin32.h for WIN32 specific includes
4632 * Do not use ptime structure or any of the posix process
4633 functions on WIN32 in lib/silccrypt/silrng.c.
4635 * Added silc_gettimeofday to provide generic function
4636 for struct timeval on all platforms. Added the function
4637 to lib/silcutil/silcutil.h.
4639 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4641 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4642 library as they clearly belong there. As a plus side we
4643 can make the actual socket connection routines platform
4646 Added also new generic function silc_socket_read and
4647 silc_socket_write (that used to be silc_packet_[read/write].
4648 The implementation of these are platform specific.
4650 * Added WIN32 specific routines of silc_socket_[read/write]
4651 to lib/silcutil/win32/silcwin32sockconn.c.
4653 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4655 * Added preliminary support for native WIN32 compilation under
4656 cygwin (using the -mno-cygwin option for GCC) to the
4657 ./configure.in.pre. The --with-win32 now prepares the
4658 compilation for native WIN32.
4660 * Rewrote the SILC Scheduler interface in the file
4661 lib/silcutil/silcschedule.h. The scheduler is now context
4662 based and does not have anymore any global static scheduler.
4663 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4664 and created lib/silcutil/win32 directory for WIN32 based
4667 * Added Unix specific network routines to the
4668 lib/silcutil/unix/silcunixnet.c and the old
4669 lib/silcutil/silcnet.c includes now only generic routines.
4671 Added WIN32 specific network routines to the
4672 lib/silcutil/win32/silcwin32net.c.
4674 * Added Unix specific utility functions from the
4675 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4677 * Added WIN32 SILC Scheduler to the file
4678 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4681 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4683 * Do not handle JOIN notify in the server if the target client
4684 is not registered (idata->registered == FALSE). The affected
4685 file is silcd/packet_receive.c.
4687 * Update the nickrec->founder in event_cumode in the Irssi SILC
4688 client. Affected file irssi/src/silc/core/silc-channels.c.
4690 * Fixed the CUMODE_CHANGE notify handling in the server when
4691 server and router are announcing their clients on channels.
4692 Now the mode changes are saved and notified correctly. The
4693 affected file is /silcd/packet_receive.c.
4695 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4696 They really did not replace the cache entry in the ID Cache.
4697 Now they do that. Affected file silcd/idlist.c.
4699 * Fixed the KICK notify handling in the Irssi SILC client to
4700 update the channel records so that the kicked client does not
4701 appear to be on the channel. The affected file is
4702 irssi/src/silc/core/silc-channels.c.
4704 * Always update the conn->current_channel when executing command
4705 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4707 * Fixed the KILL notify handling in Irssi SILC client to remove
4708 the killed client on all channels.
4710 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed the silc_parse_command_line to remove extra spaces
4713 from the start and end of the arguments. Affected file is
4714 lib/silcutil/silcutil.c.
4716 * Cancel and free any active protocol in the function
4717 silc_server_close_connection. Affected file silcd/server.c.
4719 * Cancel and free any active protocol in the function
4720 silc_client_close_connction. Affected file is
4721 lib/silcclient/client.c.
4723 * Do not execute the KILL command for clients that are in
4724 history (ie. they are not in the network). Affected file is
4727 * Fixed KILL notify handling, client does not crash anymore.
4728 Affected file irssi/src/silc/core/silc-channels.c.
4730 * Reduced the default packet buffer size from 2048 to 1024 in
4731 lib/silccore/silcpacket.c.
4733 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4734 counter to the SKE context that is incresed when the SKE library
4735 performs async operation outside the library. If the outside
4736 process frees the SKE context and FREED status will be set
4737 and the library will detect after the sync operation that the
4738 libary is freed. The affected files are
4739 lib/silcske/silcske[_status].[ch].
4741 * Resolve the client entry information in the function
4742 silc_client_channel_message to assure that NULL pointer is not
4743 passed as client entry to the application. */
4745 * Fixed the task timeout calculation to assure that there is
4746 never negative timeouts. The affected file is
4747 lib/silcutil/silcschedule.c.
4749 * Fixed the channel user mode notification sending in server.
4750 It was sent point-to-point to the router (or to server by router)
4751 but it needs to be destined to a channel. The routines now
4752 supports sending the channel user mode notifys to the channels
4753 when announcing clients and channels. Affected files are
4754 silcd/server.c and silcd/packet_receive.c.
4756 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4757 It did not actually replace the old channel entry in the cache.
4758 Affected file lib/silcclient/client_notify.c.
4760 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Fixed a possible crash in silc_packet_send_prepare. It now
4763 assures always that there is enough space in the buffer and
4764 at the tail area of the buffer (for MAC).
4766 Fixed the inbound buffer reallocation in silc_packet_read.
4767 It was old code and did not handle the reallocation correctly.
4770 The affected file is lib/silccore/silcpacket.c.
4772 * Fixed buffer overflow in silc_parse_nickname in the file
4773 lib/silcutil/silcutil.c.
4775 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * make install generates new server keys only if there is not
4780 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4783 Added check that if the NOREPLY is set then we will not send
4784 the away message. This avoids infinite loop of away messages
4785 if both clients are away. The affected file is
4786 lib/silcclient/client_prvmsg.c.
4788 * Fixed client crash if /NICK was given without arguments.
4789 Affected file lib/silcclient/command.c.
4791 * Server does not send the invite list in INVITE command back
4792 to the client if the list was not altered. Added this notion
4793 to the protocol spec as well. Affected file silcd/command.c.
4795 Fixed possible crash in INVITE command by checking the
4796 value of silc_server_get_client_route command.
4798 * Fixed the INVITE notify type handling. The arguments are now
4799 taken in correct order and client does not crash. The affected
4800 file is irssi/src/silc/core/silc-channels.c.
4802 Removed the "Inviting xxx to channel" message from the
4803 client library away and let the application handle it.
4804 Affected file lib/silcclient/command.c. Added that message
4805 to Irssi SILC client's message formats.
4807 * Fixed CMODE command crash in client. It now checks the
4808 amount of arguments correctly and does not crash. The affected
4809 file is lib/silcclient/command.c.
4811 * Do not create new channel automatically in silc_channels_join
4812 but check whether the channel by that name already exists.
4813 Affected file irssi/silc/core/silc-channels.c.
4815 * Do not send the SERVER_SIGNOFF to router if the disconnected
4816 entity was the router. Affected file silcd/server.c.
4818 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4819 SILC client as it was missing from there.
4821 Added the handling of the KICK notify to the Irssi SILC client
4822 as it was missing. Added "you have been kicked" message to
4823 Irssi SILC client's message modules formats.
4825 Added the handing of the KILL notify to the Irssi SILC client
4826 as it was missing. Added the kill message module formats
4829 The affected file is irssi/src/silc/core/silc-channels.c.
4831 * The router did not save the channel mode the server announced.
4832 Affected file silcd/packet_receive.c.
4834 * Fixed a possible crash in INFO command in server. If the
4835 server did not provide the server info it crashed. Affected
4836 file silcd/command.c.
4838 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Fixed the GETKEY command in the server to check also the
4841 global list. Otherwise the GETKEY would not work correctly
4842 in normal SILC server. Affected file silcd/command.c.
4844 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Fixed GETKEY crash, it crashed if the command did not succseed.
4848 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4851 is now real and not just an macro interface to GMP.
4853 Removed the entire GMP from the source tree and imported new
4854 NSS MPI library instead. Reason for removing GMP is that it is
4855 extremely large and compiles extremely slow. The NSS MPI
4856 is only a few files and compiles in less than 10 seconds.
4857 The speed is also about the same as GMP. The MPI is imported
4858 to lib/silcmath/mpi.
4860 If the system has GMP installed we will still use the GMP.
4861 If it is not then the NSS MPI will be compiled.
4863 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Merged a long nickname (127 characters long) crash bugfix from
4866 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4868 * Merged a freed memory reference bugfix from Irssi CVS tree.
4869 Affected file irssi/src/core/commands.c.
4871 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added the server's public key sving and verification to the
4874 server when performing the SKE. This was missing and the
4875 remote server's (or router's) public key was accepted without
4876 checking whether we have it previously or trust it at all.
4877 Affected file silcd/protocol.c.
4879 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Check in the silc_server_timeout_remote if protocol is active
4882 and make sure that the protocol's final callback is called so
4883 that all memory if freed. Affected file silcd/server.c.
4885 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * silc_server_whois_send_reply crashed the server if the nickname
4888 was 127 characters long. Affected file silcd/command.c.
4890 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added sanity check to the silc_server_new_client. If the hostname
4893 is provided inside username then check that the provided hostname
4894 really is the same as the resolved one. If the hostname was not
4895 resolved then check it from the public key. Affected file is
4896 silcd/packet_receive.c.
4898 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4899 if the server disconnected us and the connection is not valid
4900 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4902 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4903 the library to the lib/silcutil/silcutil.[ch].
4905 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Close log file after open. Affected file
4908 lib/silcutil/silclog.c.
4910 * Check whether sock == NULL in silc_client_send_packet and return
4911 if it is. Affected file lib/silcclient/silcclient.c.
4913 * Check rec->entry == NULL in the Irssi SILC Client before
4914 sending the channel message. Affecte file is
4915 irssi/src/silc/core/silc-servers.c.
4917 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Merged a splitted window bugfix from Irssi CVS tree. The
4920 affected file is irssi/src/fe-text/textbuffer-view.c.
4922 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4923 It did not print nickname.
4925 * Improved the distributions system a bit.
4927 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4930 irssi/src/fe-text/gui-window.c.
4932 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4933 to in-active server. The affected file is
4934 irssi/src/silc/core/client_ops.c.
4936 * Resolve the client in USERS command reply if the entry does
4937 not have username resolved. The affected file is
4938 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4939 command to WHOIS command to really resolve stuff. The USERS
4940 is not used any more in any critical section so WHOIS can
4941 be used even though it might be slower than IDENTIFY.
4943 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4946 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Changed the protocol API a bit more consistent in the
4949 lib/silccore/silcprotocol.[ch].
4951 * Changed the following headers to ROBODoc format:
4953 lib/silccore/silcpayload.h
4954 lib/silccore/silcprotocol.h
4955 lib/silccore/silcsockconn.h
4957 All core library headers are now formatted.
4959 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Fixed a bug in Irssi SILC client; do not show that you are
4962 server/router operator if you really are not. Affected file is
4963 irssi/src/silc/core/client_ops.c.
4965 * Renamed silc_command_free_payload to silc_command_payload_free.
4966 Affected file lib/silccore/silccommand.h
4968 * Added silcmath.h to include the prototoypes of various routines
4969 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4972 * Changed the following headers to ROBODoc format:
4974 lib/silccore/silcchannel.h
4975 lib/silccore/silccommand.h
4976 lib/silccore/silcid.h
4977 lib/silccore/silcidcache.h
4978 lib/silccore/silcmode.h
4979 lib/silccore/silcnotify.h
4980 lib/silccore/silcpacket.h
4981 lib/silcmath/silcmath.h
4983 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added checking to the server code not to start the server if
4986 ciphers and stuff are not configured properly. Affected files
4987 silcd/serverconfig.[h] and silcd/server.c.
4989 * Changed the layout of the header files of the public interfaces
4990 in the SILC libraries. The new layout supports ROBODoc
4991 documentation tool (and some others) so that it is easy to create
4992 a library reference manual. All the other headers and source
4993 code must still follow the CodingStyle document. Also source
4994 code must not include these ROBODoc stuffs, only the headers.
4995 Furthermore, all public interface headers must now be named
4996 by using `silc' prefix, example: silcapi.h, silccipher.h.
4997 Some files were renamed due to this. All the other headers
4998 must not be used as public interfaces. I will update the
4999 CodingStyle document later. Changed following headers, so far:
5001 lib/silcclient/silcapi.h
5002 lib/silccore/silcauth.h
5003 lib/silccore/silcprivate.h
5004 lib/silccrypt/silcdh.h
5006 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Removed silc_client_packet_send_flush from the client library
5011 as it is not needed. Affected file lib/silcclient/client.[ch].
5013 * Added printing of message of unresolved authentication method
5014 to the Irssi SILC client. Added it to the module formats.
5015 Removed the same message from the client library.
5017 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added new distribution feature, DISTLABEL. Every distribution
5020 can define own preprocessor label that can be used in the
5021 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5022 file distributions, acconfig.h.pre and prepare.
5024 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added Makefile.defines_int to include the actual definitions
5027 for Makefile.defines.in. Tested the new distribution system,
5028 created distributions and tested installation.
5030 * Added AWAY message printing to the Irssi SILC client. Added
5031 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5033 * Added SCONNECT command to call the SILC's CONNECT command.
5034 Cannot use CONNECT directly since Irssi uses that internally.
5035 Affected file irssi/src/silc/core/silc-servers.c.
5037 Added ACTION local command. It is same as ME command but takes
5038 the channel as mandatory argument.
5040 Rewrote some of the Irssi's help files to suite for SILC
5043 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Added Makefile.defines[.in] that should for now on be included
5046 in all Makefile.am file in the source tree. That file includes
5047 all common compilation definitions for SILC source tree.
5049 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Minor changes to the ./prepare script to change the package
5052 name according the distribution name to the configure.in.
5054 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Created new distribution system. Added file `distributions'
5057 that defines all the distributions that can be created out of
5058 the SILC source tree. The ./prepare script now reads that
5059 file to determine how to prepare the distributions. The
5060 first argument to the ./prepare is the name of the distribution
5061 and second is the version of the distribution. If given
5062 without arguments it creates the default (toolkit) distribution
5063 with the default version (defined in ./prepare).
5065 All Makefile.am files that are subject to the distributions
5066 are now named as Makefile.am.pre. These are ./Makefile.am
5067 and lib/Makefile.am. Others may be changed later.
5069 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Added invite list, ban list, some key management and connection
5072 error message printing to module formats in the Irssi SILC client.
5074 * Added new silc_client_set_away_message to set the away message
5075 that is back to the person who sent private message. The
5076 affected file lib/silcclient/silcapi.h and the
5077 lib/silcclient/client_prvmsg.c.
5079 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Fixed the private message sending in the Irssi SILC client,
5082 added local command KEY to the Irssi SILC client.
5084 Added key management and key agreement message formats to the
5085 irssi/src/fe-common/silc/module-formats.[ch].
5087 Added USERS (alias WHO) printing, server/router operator
5088 indication and LIST command printing to the module formats.
5090 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Fixed channel joining notify handling, cumode notify handling
5093 from Irssi SILC client.
5095 * Added SILC specific module-formats to the Irssi SILC client so
5096 that SILC specific message hilighting, colors etc is possible.
5097 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5099 Added channel mode, channel user mode, actions, notices,
5100 whois and whowas printing to the the module-formats.c.
5102 * Fixed a bug in channel deletion in the server. The channel
5103 is not left to the cache even if the channel founder auth mode
5104 is set when there are no users anymore on the channel. Affected
5105 file silcd/server.c.
5107 * The silc_net_localhost now resolves the entire hostname including
5108 the domain name. Affected file lib/silcutil/silcnet.c.
5110 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Changed the ask_passphrase client operation to be ascynchronous.
5113 It has now a completion callback and a context that the
5114 application must call after it has got the passphrase from
5115 the user. Affected files lib/silcclient/silcapi.h,
5116 lib/silcclient/protocol.c, lib/silcclient/command.c and
5119 Added SilcAskPassphrase callback that the application calls
5120 to deliver the passphrase to the library.
5122 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5123 The public key verification and especially a certificate
5124 verification is asynchronous procedure.
5126 Added new SILC_SKE_STATUS_PENDING status to indicate the
5127 request is pending and a callback will be called to finalize
5130 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5131 indicate that remote end did not send its public key (or
5132 certificate), even though we require it. Added check for this
5133 condition in the SKE. This was a security bug, now fixed.
5135 Defined new SilcSKEVerifyCbCompletion callback that is called
5136 when the verification process is completed.
5138 The affected files lib/silcske/silcske_status.h and
5139 lib/silcske/silcske.[ch].
5141 * Changed the verify_public_key client operation to be async
5142 as well. Defined SilcVerifyPublicKey callback that is used to
5143 indicate the success of the public key verification process.
5145 Changed the server and client to use the new async client
5148 * Changed the Irssi SILC client's internal scheduler to be called
5149 twice as many times as it used to be. As a result the client
5150 should be a bit faster now. Affected file is
5151 irssi/src/silc/core/silc-core.c.
5153 * Added support to Irssi SILC client of asynchronous public key
5154 verification and passphrase inquiry. Affected file is
5155 irssi/src/silc/core/silc-core.c.
5157 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Do not say "You have left channel %s" in client library.
5160 Moved it to the application. Affected files are
5161 lib/silcclient/command.c and silc/client_ops.c.
5163 * Fixed silc_client_get_clients. Command context was not
5164 duplicated and was freed memory in the callback. Affected
5165 file lib/silcclient/idlist.c.
5167 * Do not say "you are now talking..." on JOIN command in the
5168 client library. The appliation must handle it.
5170 * Do not say ".. changed topic to" in command reply in the
5171 client libary. The application must handle it.
5173 * Fixed TOPIC command sending in the client library.
5175 * Fixed a memory leak in silc_client_command_free in the file
5176 lib/silcclient/command.c.
5178 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Imported a modified version of Irssi client to the source tree.
5181 The Irssi will be used to create a new client called
5182 Irssi SILC. Imported to irssi/.
5184 Added silc_core_init_finish function to the Irssi. Affected
5185 file irssi/configure.in.
5187 A lot changes in the Makefile.ams around the irssi tree.
5189 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Do not rehash if the new size is same as the old size of the
5192 hash table, in the silc_hash_table_rehash*. The affected file
5193 lib/silcutil/silchashtable.c.
5195 * Replaced hash_table_del_by_context calls from the server
5196 (when channel->user_list and client->channels) to the
5197 hash_table_del as it is sufficient and faster.
5199 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added silc_hash_table_list, silc_hash_table_get and the
5202 SilcHashTableList structure to provide an alternative way to
5203 traverse the hash table. The affected files are
5204 lib/silcutil/silchashtable.[ch].
5206 * Changed the server's idlist routines to use the hash table
5207 routines to optimize the code.
5209 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Replaced the client entry's `channel' list and channel entry's
5212 `user_list' list to hash tables for optimized lookup. Changed
5213 the code to use the hash table interface around the code.
5214 Affected file lib/silcd/idlist.[ch].
5216 * Added `auto_rehash' boolean argument to the function
5217 silc_hash_table_alloc to indicate whether the hash table should
5218 auto-rehash when it thinks is appropriate time. It will
5219 increase the hash table size if the there is twice as much
5220 entries in the table than the size of the table, and will
5221 decrease the size if there are twice as less entries than
5222 the size of the table.
5224 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5228 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * silc_idcache_purge_by_context deletes the entry now by context
5231 as it is supposed to do. Affected file lib/silccore/idcache.c.
5233 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5234 client is not anymore valid (WHOWAS givens the info) and not
5235 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5237 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Removed the `data' and `data_len' arguments from the ID Cache
5240 interfaces and added `name' argument. ID Cache does not handle
5241 anymore the binary data only a names associated with given ID.
5243 * When hashing a Client ID with silc_hash_id the entire ID is
5244 not hashed anymore, instead only the hash of the Client ID is
5245 hashed. This way we can access the Client ID from the cache
5246 with Client ID but with the hash of the ID (which is a hash of
5247 the nickname) as well without any difference in performance.
5249 Added also silc_idcache_find_by_id_one_ext to do one on one
5250 searching when we have the actual ID. Added also function
5251 silc_hash_client_id_compare. The affected files are
5252 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5254 * When hashing the name associated with a ID it is always done
5255 in lowercase. This way we can access the cache without worrying
5256 about case-sensitivity, even though, for example nicknames are
5259 * Fixed a bug in server with channel message sending. It put
5260 wrong ID type as destination ID. The affected file
5261 silcd/packet_send.c.
5263 * silc_idcache_del_by_context now deletes from all hash tables
5264 by context. Affected file lib/silccore/idcache.c.
5266 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Changed the client library to use the new ID Cache interface.
5269 Changes around the source tree.
5271 * Added silc_hash_table_rehash_ext to rehash with specific
5272 hash function. Affected file lib/silcutil/silchashtable.[ch].
5274 * Added silc_hash_string_compare to compare two strings in the
5275 hash table. Affected file lib/silcutil/silcutil.[ch].
5277 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Added new function silc_idcache_del_by_context into the
5280 lib/silccore/idcache.[ch].
5282 * Changed the server's ID list routines to use the new ID Cache
5283 interface. Changes around the source tree.
5285 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Added silc_hash_table_del[_by_context]_ext functions in to the
5288 lib/silcutil/silchashtable.[ch].
5290 Removed silc_hash_table_find_all* routines and added new
5291 silc_hash_table_find_foreach to replace them.
5293 Added silc_hash_table_replace_ext function as extended
5294 replacing function. Separated the simple hash table interface
5295 from the extended hash table interface in the file
5296 lib/silcutil/silchashtable.h.
5298 * Fixed minor bugs and changed it to use some of the new
5299 hash table functions in lib/silccore/idcache.c
5301 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added new function silc_hash_table_find_all to return all keys
5304 in the hash table by the specified key. As the hash table is
5305 collision resistant it also makes it possible to have several
5306 duplicate keys in the hash table. This function may be used to
5307 find all of the keys from the hash.
5309 Added user_context arguments to the SilcHashFunction,
5310 SilcHashCompare and SilcHashDestructor to deliver user specified
5313 Added new fuctions silc_hash_table_find[_all]_ext to do
5314 extended lookup with specified hash and compare functions and
5315 specified user contexts.
5317 Added new function silc_hash_table_add_ext to add the key
5318 with specified hash function and user context.
5320 Added new function silc_hash_table_foreach to traverse all
5321 entrys in the hash table. Added SilcHashForeach callback
5324 Added new function silc_hash_table_del_by_context to delete
5325 the entry only if the context associated with the key matches.
5327 Affected files are lib/silcutil/silchashtable.[ch].
5329 * Removed silc_hash_[server/client/channel]_id and added just
5330 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5331 silc_hash_id_compare to compare two ID's using as the hash table
5332 comparison function. Added also silc_hash_data to hash
5333 binary data and silc_hash_data_compare to compare it.
5335 * Removed silc_idlist_find_client_by_hash as it is not needed
5336 anymore. Affected file silcd/idlist.[ch].
5338 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5339 to use internally the SilcHashTable. The new ID Cache is a lot
5340 faster than the old one. Some of the ID Cache interface was also
5341 rewritten and obsolete and stupid functions were removed.
5343 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Added entry_count field to the SilcHashTable to keep the number
5346 of the entries in the table. Implemented the function
5347 silc_hash_table_rehash. Added new function
5348 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5350 Fixed a minor bug in silc_hash_table_free.
5352 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5353 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5354 into the lib/silcutil/silcutil.[ch].
5356 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Implemented a collision resistant hash table into the
5359 lib/silcutil/silchashtable[ch]. See the header and the source
5360 for the SilcHashTable API.
5362 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Merged dotconf version 1.0.2 into lib/dotconf.
5366 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Do not compile anything in lib/silcsim/* if the SIM support
5369 is not enabled. The tree should now compile without problems
5372 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Compiled the SILC under cygwin. Compiled and tested briefly
5375 without problems. More tests needed. The SIMs didn't compile
5378 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5380 * Fixed possible crash in silc_get_username in the
5381 lib/silcutil/silcutil.c.
5383 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Fixed a va_arg in silc/client_ops.c.
5387 * Oops, RC5 routines were named AES and caused some problems
5388 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5390 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Added new SilcIDIP structure into the lib/silccore/id.h and
5393 replaced the old `ip' fields from all SILC ID's to that type.
5394 This is a step towards IPv6 support.
5396 The silc_id_get_len takes now the ID as an extra argument.
5397 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5398 both IPv4 and IPv6 based ID's.
5400 The affected files are lib/silccore/id.[ch] and other files
5401 around the tree using these routines.
5403 * Removed the ID length arguments in server from various
5404 silc_server_send_notify_* routines -> they are not needed
5407 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Fixed memory leak in silc_encode_pem_file in the file
5410 lib/silcutil/silcutil.c.
5412 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Check minor version as well in the SKE. Affected files are
5415 silcd/protocol.c and lib/silcclient/protocol.c.
5417 * Added --identifier option to the server so that an identifier
5418 can be when creating the public key for the server. Affected
5419 file is silcd/silcd.c.
5421 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5422 lib/silccrypt/silcpkcs.c.
5424 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Register default ciphers and stuff when using -C option with
5427 the server. Affected file sildc/silcd.c.
5429 * Put back the servers public key filename format, it is better
5430 than the new one. For now, the client keys are saved with the
5431 new filename format. The affected file silc/client_ops.c.
5433 * Implemented the Cipher API for the rest of the ciphers that
5434 did not implement it or implemented it the wrong way.
5436 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Register default ciphers and stuff when using the -S option
5439 in the client. Affected file silc/silc.c. Same also when
5440 creating new key pair with -C option.
5442 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Fixed the silc_verify_public_key client operation function to
5445 save the public keys differently. The fingerprint is now
5446 used as filename and not the hostname. This way also the
5447 client keys are saved uniquely and not with hostnames. The
5448 affected file is silc/client_ops.c.
5450 * Trimmed the silc_hash_fingerprint function to remove extra
5451 whitespaces from the end of the fingerprint. The affected
5452 file is lib/silccrypt/silchash.c.
5456 * Added silc_cipher_register_default function to register all
5457 default ciphers. It can be used when configuration files
5458 does not exist and the application does not want any specific
5459 ciphers in any specific order.
5461 The SilcDList is now used as silc_cipher_list dynamically
5462 allocated cipher list. Removed the static list all together
5463 and now all ciphers must be allocated to the dynamic list.
5464 The silc_cipher_alloc routine was changed to check only the
5467 All silc_cipher_* routines that used to return int returns
5470 The affected files lib/silccrypt/silccrypt.[ch].
5472 * The same thing was done to silc_hash_* as for silc_cipher_*
5473 routines. Affected files lib/silccrypt/silchash.[ch].
5475 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5476 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5477 Added also silc_pkcs_[un]register[_default] functions.
5478 Removed the data_context from the PKCS API.
5480 * Added silc_hmac_register_default function to register default
5481 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5482 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5483 to unregister all hmacs at once.
5485 * Register the default ciphers, hash functions, PKCSs and HMACs
5486 if client's configuration file does not exist. The affected
5489 * The client did not load the hash functions from the SIM
5490 modules at all. Added support for this. Affected file is
5491 silc/clientconfig.c.
5493 * When decoding public key with silc_pkcs_public_key_decode, check
5494 the supported algorithm only if PKCS are registered. Affected
5495 file lib/silccrypt/silcpkcs.c. The same was done with the
5496 silc_pkcs_private_key_decode.
5498 * Fixed the SILC List routines to keep the list always in order.
5499 It used to change the list's order when traversing the list but
5500 not it preserves the order. Affected file lib/trq/silclist.h.
5502 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added the client library to use the SilcSocketConnection's
5505 reference counter (by silc_socket_dup) to prevent the bug that
5506 the socket object may be freed underneath async operation.
5508 * The name resolv library checking fixes in the configure.in.pre.
5511 * Created new version of the protocol drafts for future
5512 development. The -03 drafts are the ones that will be changed
5513 in the trunk now and the -02 will remain as they are.
5515 * Send list of CUMODE notifys to the router when announcing
5516 the channel users to the router. Affected file silcd/server.c.
5517 If the router receiving channel founder CUMODE for a channel
5518 that already has channel founder it will send CUMODE notify
5519 to the sender to remove the channel founder rights from the
5520 announced client. Affected file silcd/packet_receive.c.
5522 * The CUMODE notify may now use Server ID as well as the entity
5523 who changes the mode. Updated protocool specs.
5525 * Updated INSTALL and README files.
5527 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * New web pages in the http://silc.pspt.fi. The pages was
5534 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Implemented the [DenyConnectin] config section in the server.
5537 Added silc_server_config_denied_conn to check whether incoming
5538 connection is denied. Affected file silcd/serverconfig.[ch].
5540 * Do not check the ports when checking the incoming configuration
5541 data if the port is 0, meaning any. Affected file is
5542 silcd/serverconfig.c.
5544 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed buffer overflow in silc_string_compare in the file
5547 lib/silcutil/silcutil.c.
5549 * Fixed double free in silc_server_command_leave in the file
5552 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Fixed the version checking in the server. Affected file is
5557 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Fixed the configuration data fetching when accepting new
5560 connections in the server. Affected file silcd/server.c.
5562 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Added `sender_entry' argument to the function
5565 silc_server_packet_relay_to_channel so that we can check
5566 whether some destination actually belongs to the same route
5567 the sender belongs (ie, we must not resend the packet to the
5568 sender). Affected file silcd/packet_send.[ch].
5570 * Added `servername' field to the SilcClientEntry in the server
5571 to hold the name of the server where client is from. Affected
5572 file is silcd/idlist.h.
5574 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Moved the channel message encrypting in the router betwen
5577 router connections from silc_server_channel_message to the
5578 silc_server_packet_relay_to_channel since we want to check
5579 whether we have anybody channel before encrypting anything.
5580 Affected files silcd/packet_[receive/send].c.
5582 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Fixed the [AdminConnection] server config section to support
5585 multiple entries. Affected file silcd/serverconfig.c.
5587 * Added support into the server to check the validity of the
5588 incoming connection before executing any KE or authentication
5591 * The connection configuration is now saved to the KE and
5592 connection auth protocol contexts and not fetched anymore in
5593 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5595 * The local hosts listenning address and port is also resolved
5596 now when starting the server. We want to have the socket object
5597 to include the real address and port for the listener. Added
5598 new function silc_net_check_local_by_sock into the files
5599 lib/silcutil/silcnet.[ch].
5601 * Fixed a broadcast bug in server -> do not broadcast if we
5604 * Fixed a routing bug. Do not route broadcast packets ever.
5605 Broadcast packets must be processed always and not routed since
5606 they may be destined to some other host than yourself and thus
5607 would get routed without no good reason. Affected file is
5610 * Added function silc_server_config_is_primary_route to check
5611 whether primary router connection has been configured (a router
5612 configuration that we are initiating). If there is not, we
5613 will assume that there is only two routers in the SILC network
5614 and we will use the incoming router connection as our primary
5615 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5617 * Changed the order of the broadcasting. Broadcast _after_ the
5618 packet has been processed not before. Affected file is
5621 * Fixed a [ClientConnection] parsing bug. The port was never
5622 parsed correctly thus resulting to port 0. Affected file
5623 silcd/serverconfig.c.
5625 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5626 argument and did not set the broadcast packet flag. Affected
5627 file silcd/packet_send.c. Fixed same bug in the function
5628 silc_server_send_notify as well.
5630 * If we receive NEW_ID packet for our own ID in the server, ignore
5633 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Removed the nickname from the Private Message Payload.
5638 Updated the code and the protocol specs.
5640 * Updated protocol specs for submitting to the IETF.
5642 * Tweaked the Random Number Generator a bit. Affected file
5643 lib/silccrypt/silcrng.c. Exported a new function
5644 silc_rng_[global]_add_noise which can be used to add more
5647 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Do not parse packets with different timeout when protocol
5650 is active -> may cause problem with rekey. Affected file
5653 * When server receives signoff notify it must not create
5654 new channel key if the client is on any channels since the
5655 sender of the signoff notify will create it.
5657 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added printing of error messages during SKE protocol from the
5660 failure packet sent by server during SKE. Affected file
5663 * Removed the client's failure_callback handling with timeout
5664 and handle it immediately when received.
5666 * The SKE library returned wrong type in SUCCESS and FAILURE
5667 packets. They must be 32 bit MSB not 16 bit MSB.
5669 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Ok, rewrote the logic of the re-key and now it seems to work.
5672 I tested it on high traffic with frequent re-keys without
5673 problems. Added hmac_receive (and renamed hmac to hmac_send)
5674 in SilcClientConnection in lib/silcclient/client.h and
5675 in SilcIDListData in silcd/idlist.h. Also, removed the
5676 SilcPacketParserContext's cipher and hmac fields as they are
5677 not needed anymore and actually caused some problems when
5678 the ciphers and hmac's changed underneath the packet parser.
5680 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * If re-key protocol is active then process the incoming packets
5683 synchronously since we must assure that icoming packets encrypted
5684 with the old key is processed before the new keys is set to
5685 use. This is true other packets than for REKEY packets.
5686 Affected file silcd/server.c. The same was done to client library
5687 as well, affected file lib/silcclient/client.c.
5689 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Fixed bug in client and server to accept the force send if
5692 the packet is send from silc_[server/client]_packet_process
5693 function. Otherwise the packets are never delivered, oops.
5695 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Disable force sending of packets when REKEY protocol is active.
5698 We must assure that no packet is sent directly when rekey is
5699 performed. All packets must be sent through packet queue.
5700 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5701 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5702 function is silc_[server/client]_packet_send_real to check
5705 * Replaced the SIM paths from example config files to
5706 /usr/local/modules. Also, make install creates now
5707 /usr/local/silc/logs directory to hold all the SILC server
5710 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Made the configure.in.pre work on Solaris. Patch by salo.
5714 * Made all ciphers compatible with non-x86 machines. Defined
5715 CBC mode macros into lib/silccrypt/ciphers_def.h.
5717 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed the make install.
5721 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * When MAC computation fails the silc_packet_decrypt returned 0
5724 even though it was supposed to return -1. Fixed this. The
5725 affected file is lib/silccore/silcpacket.c.
5727 * Do not replace the config files in /etc/silc (in make install)
5728 if they already exist. Affected file ./Makefile.am.
5730 * Do not send re-key packets immediately but through packet queue.
5731 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5733 * Changed silc_net_check_host_by_sock to return FALSE if the
5734 IP/DNS could not be resolved. Though, it returns the IP address
5735 now even if it could not resolve it (but returns also FALSE).
5736 Affected file lib/silcutil/silcnet.[ch].
5738 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Added silc_pkcs_decode_identifier to decode the public key's
5741 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5742 Added also silc_pkcs_free_identifier. Added also new context
5743 SilcPublicKeyIdentifier.
5745 * Added -S option to the silc client. It is used to dump the
5746 contents of the specified public key file.
5748 * Changed the PKCS api to return the public key length when
5749 setting the public key.
5751 * Fixed a fatal bug in the public and private key file loading.
5752 Affected file lib/silccrypt/silcpkcs.c.
5754 * Execute the packet parsing for client with zero (0) timeout
5755 if the protocol is active. Affected file silcd/server.c.
5757 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Made the key generation options to the silcd program. Added
5760 -C option, equivalent to client's option.
5762 * Added new [ServerKeys] config section to the server. It
5763 configures the server's public and private key.
5765 * Defined generic Public Key Payload into the protocol
5766 specification to send specific type of public keys and
5769 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5770 public key or certificate.
5772 * Implemented the GETKEY command to the server and to the
5773 client library and on user interface.
5775 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Made preliminary `make install' work.
5779 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Added SilcServerRekey context into silcd/idlist.h.
5783 * Added the PFS support as defined in the specification to the
5784 SKE protocol. Affected files lib/silcske/*.c.
5786 * Added `ske_group' field to the SilcServerRekey context to hold
5787 the number of the SKE group that is used with PFS in re-key.
5788 Affected file silcd/idlist.h.
5790 * Added PFS re-key support to the server. Affected file is
5793 * Added silc_protocol_cancel to cancel execution of the next
5794 state of the protocol. Affected file is
5795 lib/silccore/silcprotocol.[ch].
5797 * Added the re-key support with and without PFS to the client
5798 library. Re-key is performed once in an hour, by default.
5800 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5801 Added silc_client_rekey_callback and silc_client_rekey_final.
5802 Affected files are lib/silcclient/protocol.[ch] and
5803 lib/silcclient/client.[ch].
5805 * Removed the `hmac_key' and `hmac_key_len' fields from the
5806 SilcClientConnection structure; not needed. Affected file is
5807 lib/silcclient/client.h.
5811 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Do not ask whether user wants to use the negotiated private key
5814 for private messages, just use it. Affected file is
5815 silc/local_command.c.
5817 * Added `send_enc_key' and `enc_key_len' fields to the
5818 SilcIDListData structure since they are needed in the re-key
5819 phase. Affected file is silcd/idlist.[ch].
5821 * Implemented the simple re-key protocol into the server.
5822 Affected files silcd/server.c and silcd/protocol.[ch]. The
5823 re-key will be performed once in an hour, by default.
5825 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5826 Added silc_server_rekey, silc_server_rekey_callback and
5827 silc_server_rekey_final.
5829 * Removed Tunneled flag from the protocol. Updated the code
5830 and the specifications.
5832 * Adde `pfs' field to the SilcIDListData to indicate whether
5833 the PFS is to be performed in the re-key. Affected file is
5836 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5839 int64 of at least the xintXX size. If void * is less that 4
5840 bytes uint32 * will be used. Defined bool as boolean.
5842 * Changed _ALL_ unsigned long and unsigned int to uint32,
5843 unsgined short to uint16 in the source tree.
5845 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5846 not handle clients that has entry->data.registered == FALSE.
5847 They are not in the network anymore. Affected file is
5850 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Implemented the sending of the SERVER_SIGNOFF notify in the
5853 server. Affected file is silcd/server.c.
5855 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5856 Added also silc_notify_payload_encode_args into the
5857 lib/silccore/silcnotify.[ch].
5859 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5860 Affected file silcd/packet_receive.c.
5862 * Implemented the SERVER_SIGNOFF notify handling in the client
5863 library. Affected file lib/silcclient/client_notify.c. Also,
5864 implemnted the printing of the SERVER_SIGNOFF info to the
5865 application. Affected file silc/client_ops.c.
5867 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5868 if the deleting was successful. Affected file silcd/idlist.[ch].
5870 * Added support for public key authentication in the connection
5871 authentication protocol in the client library. Affected file
5872 lib/silcclient/protocol.c.
5874 * Changed the server's silc_idlist_get_clients_by_* interface
5875 to support already allocated array so that new entries may be
5876 added to pre-allocated array. Affected file silcd/idlist.[ch].
5877 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5878 and command replies.
5880 * All command reply functions in the server now calls the
5881 pending command callback even if error occured. This way the
5882 error will be delivered to the client as well. Affected files
5883 silcd/command.c and silcd/command_reply.c.
5885 * Fixed INFO command to return local server's info if no server
5886 was provided. Affected file lib/silcclient/command.c.
5888 * Removed RESTART command for good. Updated the code and the
5891 * Rewrote parts of the task system. It is a bit simpler now.
5892 Removed unsued task priorities. The affected files are
5893 lib/silcutil/silctask.[ch].
5895 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Moved the USERS printing from the library to the application.
5898 Affected files lib/silcclient/command.c and silc/client_ops.c.
5900 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Added channel key re-key support. The re-key is perfomed
5905 only by the router and is done once in an hour. Added `rekey'
5906 field to the SilcChannelEntry in the server. Affected files
5907 silcd/server.c and silcd/idlist.h.
5909 * Added silc_task_unregister_by_context into the file
5910 lib/silcutil/silctask.[ch].
5912 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Added SILC_UMODE_GONE mode to indicate when the client is not
5915 present in the SILC network. Added also support to the local
5916 command AWAY that will set this mode. Added support of showing
5917 "xxx is gone" in WHOIS command. The USERS command shows the
5918 gone status as well.
5920 * Fixed setting server and router operator privileges in the
5921 server's UMODE command. Affected file silcd/command.c.
5923 * Merged the SKE KE1 and KE2 payloads into one payload. The
5924 new KE payload is equivalent to the old KE2 payload.
5926 Cleaned up the SKE Start Payload parsing. It now uses the
5927 simple buffer unformatting to do the parsing. A lot faster
5930 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5931 to the SKE that is used to indicate whether both of the SKE
5932 parties should perform authentication. By default only the
5933 responder performs authentication. By setting this flag also
5934 the initiator must do authentication. By default it is unset
5935 since in normal SKE case, client to server connection, only
5936 the responder should do authentication. When doing SKE between
5937 two clients both should perform authentication. Updated the
5938 code and the protocol specs.
5940 * A little fix to IDENTIFY command in the server. Search the
5941 client first by hash not nickname. Affected file is
5944 * Fixed the silc_client_close_connection to support closing
5945 the client to client connections wihtout deleting too much
5946 data. Affected file lib/silcclient/client.c.
5948 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5949 are received if protocol used to be active but is not anymore
5950 the application would crash due to NULL pointer dereference.
5951 Affected files silcd/server.c and lib/silcclient/client.c.
5953 * Added `hash' field to the SilcClientConnection to include
5954 the hash function negotiated in the SKE protocol.
5956 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5957 to set the channel founder authentication data. A client can
5958 claim the founder rights later by providing the authentication
5959 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5960 This way the channel founder can regain the channel founder
5961 privileges even it is left the channel. This works only on
5962 local server and the client must be connected to the same
5963 server to be able to regain the founder rights. Updated the
5964 protocol specs accordingly.
5966 Added support to the CMODE command in the client to set the
5967 founder auth data. Read the README to see how to set it.
5969 Added support to the CUMODE command to claim the founder
5970 rights. Read the README to see how to do it.
5972 Added support for the founder authentication to the Channel
5973 Entry in the server. Affected file silcd/idlist.h.
5975 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5976 server's CMODE command. Affected file silcd/command.c.
5978 * Added the following new functions into lib/silccore/silcauth.[ch]:
5979 silc_auth_get_method and silc_auth_get_data.
5981 * The server now saves the remote hosts public key to the
5982 SilcIDListData pointer. Affected file silcd/protocol.c.
5984 * The normal server now does not remove the channel entry from
5985 the cache if the founder authentication data is set. It used
5986 to remove it if the founder was the last one on the channel on
5987 the server and left the channel. The auth data is saved and
5988 if the channel is re-joined later the old entry is used with
5989 the old auth data. Affected files silcd/command_reply.c and
5992 * Removed the `pkcs' field from the SilcIDListData structure
5993 in the server; it is not used. Affected file silcd/idlist.h.
5995 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Fixed packet processing on slow links. Partial packets were
5998 never re-processed because the incoming data buffer was cleared
5999 by the application. Application must not directly clear the
6000 sock->inbuf, the packet processing routines handle it. Fixed
6001 this in client library and in server.
6003 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Fixed the WHOIS and IDENTIFY send reply function to really
6006 check whether to send list or just one entry. Affected file
6009 * Cleaned up the LEAVE command's channel key distribution. The
6010 affected file silcd/command.c.
6012 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6013 can enforce the channel mode as well. In that case the ID
6014 includes the ID of the server. The code now enforces the
6015 mode change if the router have different mode than the server.
6017 * The notify client operation with CMODE_CHANGE notify can now
6018 return NULL client_entry pointer if the CMODE was not changed
6019 by client. Application must check for this.
6021 * Added <Server ID> argument to INFO command to support server
6022 info fetching by Server ID.
6024 * Added silc_server_announce_get_channel_users to get assembled
6025 packets of channel users of the specified channel. Affected
6026 file silcd/server.[ch].
6028 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6029 was freed underneath the ID Cache.
6031 * Re-announce clients when the server received CHANNEL_CHANGE
6032 notify from the router. Affected file silcd/packet_send.c.
6034 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6037 crashed since it did not handle the fact that there is no cipher
6038 called "3" and didn't check the error condition. Now fixed.
6040 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6041 flag. It can be used to send message requests.
6043 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Implemented the RESTART command in the client.
6047 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6048 notice type messages. Added notice printing to the user
6051 * The channel keys are not re-generated if the channel's mode
6052 is PRIVKEY, ie private key on the channel exists. Affected
6053 files silcd/server.c and silcd/command.c.
6055 * Fixed a little bug in channel message delivery when channel
6056 private keys are set in the server. Affected file is
6057 silcd/packet_send.c.
6059 * Changed the setting on channel->on_channel = TRUE from the
6060 silc_client_save_channel_key to the JOIN command reply. The
6061 key payload is not received if the private channel key is set.
6062 Affected file lib/silcclient/command_reply.c and the
6063 lib/silcclient/client_channel.c.
6065 * When the CMODE_CHANGE notify is sent and the channel private
6066 key mode is removed the channel key must be re-generated in
6067 other cells as well. Added this support for the router in the
6068 silcd/packet_receive.c.
6070 * Added new local command NOTICE to send notice message on
6071 channel. Affected file silc/local_command.[ch].
6073 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Added new local command ME to the client. It is used to send
6076 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6077 some action. Affected file silc/local_command.[ch].
6079 * Changed channel_message and private_message client operations
6080 to deliver the message flags to the application. Added also
6081 the `flags' arguments to the silc_client_send_channel_message
6082 and silc_client_send_private_message functions. Affected file
6085 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Redefined the Private Message Payload to support private message
6088 keys and to support the new private message flags. Updated
6089 the protocol specs. Flags makes it possible to have for example
6090 CTCP style messages.
6092 * Added new type SilcPrivateMessagePayload and defined an API
6093 for it in the lib/silcclient/silcprivate.[ch].
6095 * Tested private message private keys successfully. Tested the
6096 private message key set, unset and list commands with the new
6099 * Redefined the Channel Message Payload to include the channel
6100 message flags (equal with private message flags) to support
6101 for example CTCP style messages.
6103 * Defined some of the message (for channel and private message)
6104 flags. Updated the protocol specs and added the flags to the
6105 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6107 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Added SilcKeyAgreementStatus type to the key agreement routines
6110 to indicate the current status and error if one occured.
6111 The status types are defined in the lib/silcclient/silcapi.h.
6113 * Added new local command KEY that is used to set and unset private
6114 keys for channels, set and unset private keys for private messages
6115 with remote clients and to send key agreement requests and
6116 negotiate the key agreement protocol with remote client. The
6117 key agreement is supported only to negotiate private message keys,
6118 it currently cannot be used to negotiate private keys for channels,
6119 as it is not convenient for that purpose.
6121 * Fixed a minor pending callback setting bug in the function
6122 silc_client_get_client_by_id_resolve, now the function works.
6123 Affected file lib/silcclient/idlist.c.
6125 * Added function silc_net_get_local_port to get local bound
6126 port by socket. Added to lib/silcutil/silcnet.[ch].
6128 * Added `sockets' and `sockets_count' fields to the SilcClient
6129 object. They hold the sockets of the listenning sockets in
6130 the client. Listenning sockets may be for example the key
6131 agreement server. Affected file lib/silcclient/client.[ch].
6132 Added functions the silc_client_add_socket and the
6133 silc_client_del_socket. They are exported to the application
6136 * Added ~./silc/clientkeys to support other client's public keys.
6138 * Renamed verify_server_key client operation to verify_public_key
6139 and added one argument to indicate the type of the connection
6140 (server, client etc.).
6142 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added silc_server_connection_auth_request to handle the
6145 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6146 silcd/packet_receive.[ch].
6148 * Added silc_server_send_connection_auth_request into the
6149 silcd/packet_send.c to send the connection auth request packet.
6151 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6154 * Fixed the public key authentication in responder side in the
6155 server. The `auth_data' pointer includes the SilcPublicKey
6156 not the path to the public key. Affected file silcd/protocol.c.
6158 * Implemented the public key authentication in the initiator side
6159 in the server. Affected file silcd/protocol.c.
6161 * Removed the [RedirectClient] config section from the server
6162 configuration. Is not needed and I don't want to implement it.
6164 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Cleaned up the CMODE command in the server. It now works
6167 correctly and supports all the modes defined in the protocol.
6168 Affected file is silcd/command.c.
6170 * Added `hmac_name' field to the SilcChannelEntry in the server
6171 to hold the default HMAC of the channel. It can be set when
6172 creating the channel (with JOIN command). Affected files
6175 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6176 type to indicate the change of the current cipher and hmac
6177 on the channel. Client can safely ignore the <cipher> argument
6178 (if it chooses to do so) since the CHANNEL_KEY packet will
6179 force the channel key change anyway. The <hmac> argument is
6180 important since the client is responsible of setting the new
6181 HMAC and the hmac key into use.
6183 * Fixed the CMODE command in the client library as well.
6185 * Tested CMODE command in router environment successfully.
6187 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Show the version of the remote client (or server) when connecting
6190 to the server. It is logged to the log file. Affected file
6191 is silcd/protocol.c.
6193 * Fixed the KILLED notify handling in the client library. The
6194 client must be removed from all channels when receiving the
6197 Also, do not remove the client entry when giving the KILL
6198 command but when the KILLED notify is received.
6200 * Removed silc_idlist_find_client_by_nickname from the server.
6201 Not needed anymore. Affected files silcd/idlist.[ch].
6203 * Implemented the CHANNEL_CHANGE notify type handling to the
6204 server. Affected file silcd/server.c.
6208 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Added silc_server_send_notify_invite to send the INVITE
6211 notify between routers.
6213 * Implemented the INVITE command correctly to the server.
6215 * Implemented the INVITE notify type handling in the server.
6217 * Implemented the INVITE command to the client library and on the
6220 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Added function silc_server_get_client_resolve to find the
6223 client entry by ID from all ID lists and then resolve it
6224 (using WHOIS) if it cannot be found. Affected file is
6227 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Implemented the BAN command to the client library.
6231 * The JOIN command in the server now checks the invite list
6234 * Changed the silc_command_reply_payload_encode_va and the
6235 silc_command_payload_encode_va to support that if argument is
6236 NULL it ignores and checks the next argument. Affected file
6237 lib/silccore/silccommand.c.
6239 * Added silc_server_send_notify_ban to send the BAN notify
6240 type between routers.
6242 * Chaned the silc_notify_payload_encode to support that if
6243 argument is NULL it ignores and checks the next argument.
6244 Affected file lib/silccore/silcnotify.c.
6246 * Tested ban lists in router environment successfully.
6248 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Implemented BAN command to the server, in silcd/command.[ch].
6252 * Removed the BAN and INVITE_LIST modes from the CMODE command
6255 * Added function silc_string_match to regex match two strings.
6256 Affected files lib/silcutil/silcutil.[ch].
6258 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Redefined parts of the SilcChannelEntry in the server to support
6261 the new ban and invite lists.
6263 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Redefined the INVITE command. The same command can be used to
6266 invite individuals to the channel but also to manage the invite
6267 list of the channel (to add to and remove from the invite list).
6268 Updated the protocol specs.
6270 * Added new command SILC_COMMAND_BAN that can be used to manage
6271 the ban list of the channel. Updated the protocol specs.
6273 * Removed the channel modes: the SILC_CMODE_BAN and the
6274 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6275 in the CMODE command. The equivalent features are now available
6276 using INVITE and BAN commands. Updated the protocol specs.
6278 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6279 in the network about change in the current ban list. The notify
6280 type is not used by the client.
6282 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6283 support the invite lists.
6285 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added new function silc_string_regexify that converts string
6288 including wildcard characters into regex string that can
6289 be used by the GNU regex library. Added into the file
6290 lib/silcutil/silcutil.[ch].
6292 Added silc_string_regex_combine to combine to regex strings
6293 into one so that they can be used as one regex string by
6294 the GNU regex library. Added into the file
6295 lib/silcutil/silcutil.[ch].
6297 Added silc_string_regex_match to match two strings. It returns
6298 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6300 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Imported GNU regex to the soruce tree into lib/contrib.
6303 Fixed some compiler warning from the regex.c.
6305 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Fixed MOTD command in the server to work in router environment.
6309 * Fixed the MOTD command in the client library to support
6310 the server argument in the command.
6312 * Added `nickname_len' argument to the silc_idlist_add_client
6313 in the server, as the `nickname' argument may be binary data
6316 * Added silc_idlist_get_channels to return all channels from
6319 * Implemented LIST command to the server. Affected file is
6322 * Implemented the LIST command to the client library and on the
6325 * Added [<user count>] argument to the LIST command reply.
6326 With private channels the user count is not shown.
6328 * Updated TODO and README.
6330 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * The client entry's data.registered must be TRUE even with
6333 global client entry on global client list. The data.registered
6334 is used to check whether the client is anymore in the network,
6335 for example with WHOWAS command so it must be valid.
6337 * Fixed the WHOWAS command in the server. It now actually works
6338 in router environment. Added function into silcd/command_reply.c
6339 silc_server_command_reply_whowas_save.
6341 * Added silc_idlist_purge function to the silcd/idlist.c
6342 to periodically purge the ID Cache.
6344 * Fixed INFO command in the server. It works now in router
6345 environment. Added <server name> argument to the INFO command
6346 reply. Updated the protocol specs.
6348 * Fixed minor bug in silc_idcache_purge to not purge if the
6349 expire value is zero.
6351 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6352 they were buggy because of the WHOWAS information.
6354 * Fixed local command MSG to handle the async resolving of
6355 the remote client properly. It used to fail the first MSG.
6356 Affected file silc/local_command.c.
6358 * Added `data_len' field to SilcIDCache context.
6360 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Update TODO. Todo in commands in the server.
6364 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6367 used by routers as broadcast packet to inform other routers
6368 about the changed user mode.
6370 Implemented the notify handling in the server. Affected file is
6371 silcd/packet_receive.c. Added the function
6372 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6374 * Added new generic Channel Payload and deprecated the New Channel
6375 Payload. The New Channel Payload is now the generic Channel
6378 * Added new argument `mode' to the silc_server_send_new_channel
6379 as it is required in the Channel Payload now.
6381 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6382 and created a new and real SilChannelPayload to represent the
6383 new generic Channel Payload. Implemented the encode/decode
6384 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6386 * Added silc_server_get_client_channel_list to return the list
6387 of channels the client has joined for WHOIS command reply.
6388 Affected file silcd/server.[ch].
6390 * Implemented the channel list sending in the WHOIS command reply
6391 in server and in the client.
6393 Implemented the channel list displaying on the user interface
6394 as well. Affected file silc/client_ops.c.
6396 * Added silc_channel_payload_parse_list to parse list of Channel
6397 Payloads. It returns SilcDList list of SilcChannelPayloads.
6398 Client for example can use this function to parse the list of
6399 channels it receives in the WHOIS command reply. The caller
6400 must free the list by calling silc_channel_payload_list_free.
6401 Affected files lib/silccore/silcchannel.[ch].
6403 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Added one new argument <user mode> to the WHOIS command reply
6406 to return the mode of the user in SILC. Updated the protocol
6409 Implemented it to the server and client.
6411 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Fixed the mode printing on the user interface on joining.
6414 Affected file silc/client_ops.c.
6416 * Implemented the UMODE command and user modes in general to the
6417 client library and to the user interface.
6419 * Implemented the UMODE command to the server.
6421 * The server now sends UNKNOWN_COMMAND error status if client sends
6422 unknown command. Affected file silcd/command.c.
6424 * All server commands now handle the command identifier the right
6425 way when sending the command reply to the client. The client can
6426 use to identify the command replies with the identifier.
6428 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Added silc_server_get_client_route to resolve the route to
6431 the client indicated by the client ID. Affected file is
6434 * Added silc_server_relay_packet as general function to relay
6435 packet to arbitrary destination. This deprecates functions
6436 like _send_private_message_key, _relay_notify etc. Affected
6437 file is silcd/packet_send.[ch].
6439 Removed silc_server_send_key_agreement,
6440 silc_server_send_private_message_key and
6441 silc_server_packet_relay_notify functions from the file
6442 silcd/packet_send.[ch].
6446 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6447 server. Affected file silcd/packet_receive.[ch].
6449 * Implemented the KILL command to the client. Implemented the
6450 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6451 Affected files lib/silcclient/command[_reply].c and
6452 lib/silcclient/client_notify.c. Implemented the KILL notify
6453 printing in the user inteface.
6455 * Fixed a lot silc_parse_nick memory leaks from the client
6456 library in the file lib/silcclient/command.c.
6458 * Changed the silc_server_send_notify_on_channels's `sender'
6459 argument from SilcSocketConnection to SilcClientEntry to
6460 check the sender as entry and not as connection object and not
6461 to send to the client provided as argument. The affected file
6462 is silcd/packet_send.[ch].
6464 * The notify packets that are destined directly to the client used
6465 to not to be processed by the server. Now changed that and the
6466 server processes all notify packets. After relaying the packet
6467 to the client the notify packet is processed in the server.
6469 * The silc_server_free_client_data now checks whether there is
6470 pending outgoing traffic for the client and purges the data to
6471 the network before removing the client entry.
6473 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6476 an client is killed from the SILC Network. Updated the protocol
6479 Added new function silc_server_send_notify_killed to the
6480 silcd/packet_send.[ch].
6482 * Added function silc_server_packet_relay_notify to relay notify
6483 packets that are destined directly to a client. In this case
6484 the server does not process the notify packets but merely relays
6485 it to the client. Affected file silcd/packet_send.[ch].
6487 Added also silc_server_packet_process_relay_notify to check
6488 whereto relay the notify. Affected file is
6489 silcd/packet_receive.[ch].
6491 * Implemented the KILL command to the server.
6495 * Added the backup schema desgined last fall to the protocol
6496 specs for everyone to see. The specification is in the
6497 *-spec-xx.txt draft and the packet type definitions for the
6498 backup routers is in *-pp-xx.txt draft. Thusly, added also
6499 new packet type SILC_PACKET_CELL_ROUTERS.
6501 * A big security problem in the implementation discovered. The
6502 signoff of an client did not cause new channel key generation
6503 which it of course should've done. The channel keys must be
6504 always re-generated when client leaves (or signoffs) the channel.
6505 The silc_server_remove_from_channels funtion now handles
6506 the channel key re-generation.
6508 * Added `sender' argument to the silc_server_send_notify_on_channels
6509 to not to send the client provided as argument. Affected file
6510 silcd/packet_send.[ch].
6512 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Implemented OPER and SILCOPER commands into the server and
6517 * Added silc_auth_verify and silc_auth_verify_data to verify
6518 the authentication directly from the authentication payload.
6519 It supports verifying both passphrase and public key based
6520 authentication. Affected file lib/silccore/silcauth.[ch].
6522 * Added `hash' field to the SilcIDListData structure. It is the
6523 hash negotiated in the SKE protocol. Affected file is
6526 * Slight redesigning of the SilcAuthPayload handling routines.
6527 Do not send SilcPKCS but SilcPublicKey as argument.
6529 * Implemented the public key authentication support to the
6530 serverconfig. The public key is loaded from the provided path
6531 and saved as authentication data to void * pointer. Thus,
6532 changed the unsigned char *auth_data to void *auth_data;
6534 * Fixed SHUTDOWN command to send the reply before the server
6535 is shutdown. :) Affected file silcd/command.c.
6537 * Fixed fatal bug in CONNECT command. The hostname was invalid
6538 memory and server crashed. Affected file silcd/command.c.
6540 * Fixed fatal bug in CLOSE command. The server_entry became
6541 invalid but was referenced later in the command. Affected file
6544 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Fixed fatal bug in failure packet handling. Server ignored
6547 the failure and thus crashed when it came.
6551 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6554 that the command may be executed only once in (about) 2 seconds.
6555 The old SILC_CF_LAG flag is same but allows command bursts up
6556 to five before limiting.
6558 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6559 server code. Various commands now includes the CF_LAG_STRICT
6560 flag to disallow any kind of miss-use of the command.
6562 * Fixed the silc_buffer_unformat to not to allocate any data
6563 if the length of the data is zero. It used to allocate the
6564 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6566 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Changed the format of AdminConnection configuration section
6569 in the server. Added username of the admin to the format.
6570 Affected files silcd/serverconfig.[ch].
6572 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6573 to return admin configuration data by host, username and/or
6576 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Implemented WHOWAS command to the server. Added the functions:
6580 silc_server_command_whowas_parse,
6581 silc_server_command_whowas_send_reply,
6582 silc_server_command_whowas_from_client and
6583 silc_server_command_whowas_from_server
6585 * Added <Client ID> argument to the WHOWAS command reply. Updated
6586 the protocol specs accordingly.
6588 * Implemented WHOWAS command and command_reply to the client
6591 Implemented the WHOWAS printing on the user interface.
6593 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Added new argument to the WHOWAS command reply, the real name.
6596 It is an optional argument. Updated the protocol specs.
6598 * Added SilcIDCacheDestructor callback that is registered when
6599 the SilcIDCache is allocated. The callback is called when
6600 an cache entry in the ID Cache expires, or is purged from the
6601 cache. Added into lib/silccore/idcache.[ch].
6603 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6604 to destruct the client entries when the cache entry expires.
6605 Other ID Cache's in server and in the client library ignores
6608 * If the ID Cache entry's `expire' field is zero then the entry
6609 never expires. Added boolean `expire' argument to the
6610 silc_idcache_add function in the lib/silccore/idcache.[ch].
6611 If it is TRUE the default expiry value is used.
6613 * Added silc_server_free_client_data_timeout that is registered
6614 when client disconnects. By default for 5 minutes we preserve
6615 the client entry for history - for WHOWAS command.
6617 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Added support to the server to enforce that commands are not
6620 executed more than once in 2 seconds. If server receives
6621 commands from client more frequently, timeout is registered
6622 to process the commands. Affected file silcd/command.c.
6623 Added new function silc_server_command_process_timeout.
6625 * Changed NICK_NOTIFY handling in client library to check that
6626 if the client's nickname was changed, so there is no need to
6627 resolve anything from the server.
6629 * Removed error printing from the WHOIS and IDENTIFY commands.
6630 If error occurs then it is ignored silently in the client library.
6631 The application, however, may map the received error to
6632 human readable error string. The application currently maps
6633 the NO_SUCH_NICKNAME error to string.
6635 * Made the command status message public to the application. Moved
6636 them from lib/silcclient/command_reply.c to
6637 lib/silcclient/command_reply.h. The application can map the
6638 received command status to the string with the
6639 silc_client_command_status_message function.
6641 * Added check to the server to check that client's ID is same
6642 as the Source ID in the packet the client sent. They must
6645 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added dist-bzip hook to the Makefile.am to make bzip2
6648 compressed distributions.
6650 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Server now enforces the maximum length for the nickname and
6653 the channel as protocol specification dictates. 128 bytes for
6654 nickname and 256 bytes for channel name.
6656 * Moved the WHOIS printing to the application. The client libary
6657 does not print out the WHOIS information anymore, the application
6658 must do it. Renamed silc_client_command_reply_whois_print to
6659 the silc_client_command_reply_whois_save.
6661 The client's idle time is also sent to the application now, and
6662 the idle is shown on screen.
6664 * Added silc_client_command_reply_identify_save to save the
6665 received IDENTIFY entries.
6667 * Do not check for channel private keys in message sending and
6668 reception if the channel does not have the PRIVKEY mode set.
6669 Affected file lib/silclient/client_channel.c.
6671 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6674 just surfaced after chaning the JOIN procedure.
6676 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Added silc_client_get_clients_by_list to get client entries
6679 from Client ID list, that is returned for example by JOIN
6680 and USERS command replies. The application should use this
6681 function for example when JOIN command reply is received to
6682 resolve the clients already on the channel (library does not
6683 do that anymore as USERS command reply is not used in the JOIN
6684 procedure anymore). Affected files lib/silcclient/silcapi.h and
6685 lib/silcclient/idlist.c.
6687 * JOIN command reply and USERS command reply returns now SilcBuffer
6688 pointers instead of unsigned char pointers when returning
6689 the client list and mode list.
6691 * Added <Client ID> argument to the JOIN command reply, mainly
6692 for the server to identify for which client the command was
6693 originally sent. Updated protocol specs accordingly.
6695 * Added SilcDlist private_key pointer to the SilcChannelEntry
6696 in the client to support the channel private keys. Affected
6697 file is lib/silcclient/idlist.h.
6699 * Added SilcChannelPrivateKey argument to the function
6700 silc_client_send_channel_message so that application can choose
6701 to use specific private ke if it wants to. If it is not provided,
6702 the normal channel key is used, unless private keys are set.
6703 In this case the first (key that was added first) is used
6704 as the encryption key.
6706 * Implemented the support for channel private key handling.
6707 Implemented the following functions:
6709 silc_client_add_channel_private_key,
6710 silc_client_del_channel_private_keys,
6711 silc_client_del_channel_private_key,
6712 silc_client_list_channel_private_keys and
6713 silc_client_free_channel_private_keys
6715 Affected file lib/silcclient/client_channel.c.
6717 * Added the support for the private keys in the channel message
6718 sending and encryption and in the message reception and
6719 decryption. Affected funtions are
6720 silc_client_send_channel_message and silc_client_channel_message.
6722 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Added SKE's key verify callback to the client library's
6725 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6727 * Removed the statement that server (or router) must send USERS
6728 command reply when joining to the channel so that the client
6729 knows who are on the channel. Instead, the client list and
6730 client's mode list is now sent in the JOIN command reply to the
6731 client who joined channel. This is better solution.
6733 * Added function silc_server_get_users_on_channel and function
6734 silc_server_save_users_on_channel to the silcd/server.[ch].
6736 * Removed function silc_server_command_send_users from the
6739 * Do not show topic on the client library anymore. The topic is
6740 sent in the command reply notify to the application and the
6741 application must show the topic now.
6743 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Added client searching by nickname hash into the IDENTIFY and
6746 WHOIS commands in the server as they were clearly missing from
6747 them. Affected file is silcd/command.c.
6749 * Fixed a bug in private message receiving in the client library.
6750 The remote ID was freed and it wasn't supposed, now it is
6753 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Minor fix to the channel payload; allocate the data area, as it
6756 needs to be of specific length.
6758 * If the key agreement port is zero then the operating
6759 system will define the bound port. Affected files are
6760 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6762 * Added new function silc_channel_payload_decrypt into the file
6763 lib/silccore/silcchannel.[ch].
6765 * Moved the channel message etc, check from silc_packet_decrypt
6766 to applications. The library calls now a generic
6767 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6768 when the packet is either normal or special. This was done to
6769 allow more wide range of checking that was not allowed when
6770 the code was in library. Now applications can do virtually any
6771 checks to the packet and return to the library the decision how
6772 the packet should be processed. Affected files are
6773 lib/silccore/silcpacket.[ch].
6775 Added silc_server_packet_decrypt_check to the server and
6776 silc_client_packet_decrypt_check to the client library.
6778 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6779 to send with specified source and destination information.
6781 * Channel message delivery between routers was broken after the
6782 channel key distribution was fixed earlier. The channel key
6783 was used be to distributed to other routers as well which is not
6784 allowed by the protocol. Now this is fixed and channel keys
6785 really are cell specific and the channel message delivery between
6786 routers comply with the protocol specification.
6788 * Fixed various commands in server to check also the global list
6789 for the channel entry and not just the local list. The affected
6790 file silcd/command.c.
6792 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Added assert()s to buffer formatting and unformatting routines
6795 to assert (if --enable-debug) when error occurs. Affected
6796 file: lib/silcutil/silcbuffmt.c.
6798 * Changed to auto-reconnect to check whether the remote host is
6799 router and register the re-connect timeout if it is. It used
6800 to check that whether we are normal server, but router must do
6801 auto-reconnect with another router as well. Affected file
6804 * Removed the [<key len>] option from CMODE command as the cipher
6805 name decides the key length, nowadays. See the defined ciphers
6806 from the protocol specification.
6808 * Added [<hmac>] option to the CMODE command to define the HMAC
6809 for the channel. Added SILC_CMODE_HMAC channel mode.
6811 * Added [<hmac>] option for the JOIN command so that user can
6812 select which HMAC is used to compute the MACs of the channel
6815 * Added Hmac field to the Channel Message Payload. The integrity
6816 of plaintext channel messages are now protected by computing
6817 MAC of the message and attaching the MAC to the payload. The
6818 MAC is encrypted. Now, it is clear that this causes some
6819 overhead to the size of the packet but rationale for this is that
6820 now the receiver can verify whether the channel message decrypted
6821 correctly and also when private keys are set for the channel the
6822 receiver can decrypt the packet with several keys and check from
6823 the MAC which key decrypted the message correctly.
6825 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6826 lib/silccrypt/silccipher.[ch].
6828 * Added silc_hash_len to return the digest length into the
6829 lib/silcrypt/silchash.[ch].
6831 * Rewrote parts of Silc Channel Payload interface in the
6832 lib/silccore/silcchannel.[ch]. The encode function now also
6833 encrypts the packet and parse function decrypts it.
6835 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Fixed a minor formatting bug in the SKE's key material processing.
6838 It actually might have processed the keys wrong way resulting
6841 * Redefined the mandatory HMAC algorithms and added new algorithms.
6842 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6843 and hmac-md5 truncated to 96 bits. The mandatory is now
6844 hmac-sha1-96. Rest are optional (including the one that used
6845 to be mandatory). Rationale for this is that the truncated HMAC
6846 length is sufficient from security point of view and can actually
6847 make the attack against the HMAC harder. Also, the truncated
6848 HMAC causes less overhead to the packets. See the RFC2104 for
6851 * Added new [hmac] configuration section. The SKE used to use
6852 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6853 is of course wrong. The official names that must be proposed in
6854 the SKE are the ones defined in the protocol specification
6855 (hmac-sha1-96 for example). The user can configure any hmac
6856 using any hash function configured in the [hash] section. At
6857 least, the mandatory must be configured.
6859 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6861 * Added HMAC list to the SKE proposal list. It has now both
6862 hash algorithm list and HMAC list. This makes the protocol
6863 incompatible with previous versions. The SKE now seems to work
6864 the way it is supposed to work, for the first time actually.
6866 * Defined plain Hash algorithms to the protocol specification.
6869 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Implemented support for key agreement packets into the server.
6872 Added functions silc_server_key_agreement and
6873 silc_server_send_key_agreement. Other than these functions,
6874 server has nothing to do with this packet.
6876 * Added support for private message key packets into the server.
6877 Added functions silc_server_private_message_key and
6878 silc_server_send_private_message_key.
6882 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6883 called in the protocol's final callback instead in the END
6884 protocol state. This makes a little more sense and in the same
6885 time in client we can use the same protocol routines for normal
6886 key exchange and to key agreement packet handling as well.
6888 * Added to both client's and server's KE protocol context the
6889 SilcSKEKeyMaterial pointer to save the key material. We will
6890 bring the key material to the protocol's final callback by doing
6891 this. The final callback must free the key material.
6893 * Added SKE's packet_send callback into client's KE protocol
6894 context so that the caller can choose what packet sending function
6895 is used. This way we can use different packet sending when
6896 doing normal SKE when doing key agreement packet handling (in
6897 the key agreement packet handling we do not want to encrypt
6900 * Implemented the responder side of the key agreement routines
6901 in the client. The client can now bind to specified port and
6902 accept incoming key negotiation. The key material is passed
6903 to the application after the protocol is over.
6905 * Implemented the processing of incoming Key Agreement packet
6906 in the client. Added function silc_client_key_agreement to
6909 * Implemented the intiator side of the key agreement routines
6910 in the client. The client can now initiate key agreement with
6911 another remote client. The key material is passed to the
6912 application after the protocol is over.
6914 * Created client_keyagr.c to include all the key agreement
6917 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6918 SILC_TASK_CALLBACK except that it is not static.
6920 * Created client_notify.c and moved the Notify packet handling
6921 from the client.[ch] into that file.
6923 * Created client_prvmsg.c and moved all private message and
6924 private message key routines from the client.[ch] into that file.
6926 * Create client_channel.c and moved all channel message and
6927 channel private key routines from the client.[ch] into that file.
6929 * Changed silc_client_get_client_by_id_resolve to resolve with
6930 WHOIS command instead of IDENTIFY command, in the file
6931 lib/silclient/idlist.c.
6933 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Implemented the SKE's responder side to the Client library.
6937 * When FAILURE is received to the protocol do not trust it
6938 blindly. Register a timeout to wait whether the remote closes
6939 the connection as it should do it, only after that process the
6940 actual failure. This was changed to both client and server.
6942 * Added client_internal.h to include some of the structures
6943 there instead of client.h in lib/silcclient/.
6945 * Added function silc_task_unregister_by_callback to unregister
6946 timeouts by the callback function.
6948 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Some "Incomplete WHOIS info" errors has been appearing on the
6951 log files. Took away the entry->userinfo check from WHOIS
6952 reply sending. The entry->userinfo is now " " if client did not
6953 provide one. I thought this was fixed earlier but something
6954 is wrong still. Let's see if the error still appears.
6956 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Fixed a minor bug in the login when the channel key is
6959 re-generated in the server. It used to generate the key in
6960 wrong order and thus caused problems in the channel traffic.
6962 * Fixed a minor bug in channel key distsribution after
6963 KICK command. The key was not sent to the router even though
6966 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Added silc_ske_process_key_material_data as generic routine
6969 to process any key material as the SILC protocol dictates. The
6970 function is used by the actual SKE library but can be used by
6971 applications as well. This relates to the private message keys
6972 and the channel private keys since they must be processed the
6973 same way the normal SILC session keys. The protocol dictates
6974 this. Affected files: lib/silcske/silcske.[ch].
6976 Added also silc_ske_free_key_material to free the
6977 SilcSKEKeyMaterial structure.
6979 * Defined silc_cipher_set_key function to set the key for
6980 cipher without using the object's method function. The affected
6981 files: lib/silccrypt/silccipher.[ch].
6983 * Implemented silc silc_client_add_private_message_key,
6984 silc_client_add_private_message_key_ske,
6985 silc_client_del_private_message_key,
6986 silc_client_list_private_message_keys and
6987 silc_client_free_private_message_keys functions in the
6990 Added functions silc_client_send_private_message_key to send
6991 the Private Message Key payload and silc_client_private_message_key
6992 to handle incoming Private Message Key payload.
6994 * Added Cipher field to the Private Message Key payload to set
6995 the cipher to be used. If ignored, the default cipher defined
6996 in the SILC protocol (aes-256-cbc) is used.
6998 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7000 * Removed lib/silcclient/ops.h file.
7002 Redefined parts of the SILC Client Library API. Created new
7003 file silcapi.h that deprecates the ops.h file and defines the
7004 published Client Library API. Defined also private message key
7005 API and channel private key API into the file.
7007 This is the file that the application must include from the
7008 SILC Client Library. Other files need not be included by
7009 the application anymore.
7011 * Added new key_agreement client operation callback and also
7012 defined the Key Agreement library API for the application.
7014 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7017 is used by clients to request key negotiation between another
7018 client in the SILC network. If the negotiation is started it
7019 is performed using the SKE protocol. The result of the
7020 negotiation, the secret key material, can be used for example
7021 as private message key.
7023 Implemented the Key Agreement payload into the files
7024 lib/silccore/silauth.[ch].
7026 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Redefined ciphers for the SILC protocol. Added some new ciphers
7029 and defined the key lengths for the algorithms. Changed the
7030 code accordingly. The default key length is now 256 bits.
7032 * Fixed SKE key distribution function silc_ske_process_key_material
7033 when the key length is more than 128 bits. The default key
7034 length in SILC is now 256 bits.
7036 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7037 to indicate unsupported algorithm.
7039 * Renamed rijndael.c to aes.c and all functions as well.
7041 * Fixed a long standing channel key setting bug in client library.
7042 Weird that it has never surfaced before.
7044 * Fixed bug in channel deletion. If the entire channel is removed
7045 then it must also delete the references of the channel entry
7046 from the client's channel list as the client's channel entry and
7047 the channel's client entry share same memory.
7049 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Implemented CONNECT and SHUTDOWN commands in the client.
7053 * Implemented CLOSE command to the client.
7055 * Added the function silc_idlist_find_server_by_name into the
7056 files silcd/idlist.[ch].
7058 Added the function silc_idlist_find_server_by_conn into the
7059 files silcd/idlist.[ch].
7061 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * DIE command was renamed to SHUTDOWN. Updated the both code
7066 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7067 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7069 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7072 * Added function silc_server_create_connection function to create
7073 connection to remote router. My server implementation actually
7074 does not allow router to connect to normal server (it expects
7075 that normal server always initiates the connection to the router)
7076 so the CONNECT command is only good for connecting to another
7079 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7081 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7082 or some other client was kicked from the channel.
7084 Implemented the handling of the notify type to both client
7087 Implemented silc_server_send_notify_kicked to send the KICKED
7088 notify. It is used to send it to the server's primary router.
7090 * Implemented the KICK command into server and client.
7092 * Added `query' argument to the silc_idlist_get_client function
7093 to indicate whether to query the client from server or not if
7096 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7097 to indicate that the client is not channel founder.
7101 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Removed the rng context from SilcPacketContext structure and
7104 changed that the packet routine uses the Global RNG API.
7106 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Added support for quit message that client can "leave" on the
7109 channel when it quits the SILC. It is ditributed inside the
7110 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7112 Added silc_server_free_client_data that will take the
7113 signoff message as argument.
7115 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7117 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Updated parts of the protocol specification to keep it up
7122 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7125 payloads in one packet.
7127 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7128 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7129 use now the new List flag.
7131 * Also deprecated the following packet types: REPLACE_ID,
7132 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7134 * Added list support for Notify packet in server.
7136 * Added silc_server_send_notify_channel_change to send the
7137 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7138 the silc_server_send_replace_id.
7140 * Added silc_server_send_notify_nick_change to send the
7141 NICK_CHANGE notify type. Deprecates the function
7142 silc_server_send_replace_id.
7144 * Added silc_server_send_notify_join to send the JOIN notify type.
7145 Deprecates the function silc_server_send_new_channel_user.
7147 * Added silc_server_send_notify_leave to send LEAVE notify type.
7148 Deprecates the function silc_server_send_remove_channel_user.
7150 * Added silc_server_send_notify_cmode and
7151 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7152 types. Deprecates the silc_server_send_set_mode function.
7154 * Added SERVER_SIGNOFF notify type to indicate that server has
7155 quit. This means that all clients on the channel from that
7156 server will drop. This can be also used when netsplit happens.
7158 Deprecated REMOVE_ID packet type since it is not needed anymore
7161 Added silc_server_send_notify_server_signoff to send the
7162 SERVER_SIGNOFF notify type. Deprecates the function
7163 silc_server_send_remove_id.
7165 Added also silc_server_send_notify_signoff to send the
7166 SIGNOFF notify type.
7168 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7169 SILC protocol from this day on. Changed the protocol
7170 specification as well.
7172 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7173 notify type. It is used between routers to notify about
7174 topic changes on a channel.
7176 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7179 * Partly updated the protocol specification to comply with the
7180 changes now made. It is still though a bit outdated.
7182 * The JOIN notify type now takes one extra argument <Channel ID>.
7183 The packet used to be destined to the channel but now the
7184 JOIN type may be sent as list thus it is impossible to
7185 destine it to any specific channel. By adding this argument
7186 it is again possible.
7188 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Added CREDITS file. The CHANGES and CREDITS file will appear
7191 in the distribution as well.
7193 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7196 types in the server's silcd/packet_receive.c.
7198 * Implemented CMODE and CUMODE to work in router environment.
7200 * Fixed minor encoding and decoding buglet from the
7201 lib/silccore/silcmode.c.
7203 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7206 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7208 * Changed all SilcConfigServer* and silc_config_server* to
7209 SilcServerConfig* and silc_server_config*, respectively.
7212 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7214 * Associated the ID (client or server ID) to the Authentication
7215 Payload to avoid any possibility of forging. Updated the
7216 protocol specification and the code accordingly.
7218 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * The RSA key length is now save to the RsaKey context in the
7221 key generation process in lib/silccrypt/rsa.c. The key length
7222 is now used to figure out the maximum size of the block allowed
7223 to be encrypted/signed.
7225 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7226 is equivalent to the silc_mp_mp2bin but does not allocate any
7229 * Changed silc_mp_mp2bin API to take length argument. If it is
7230 non-zero then the buffer is allocated that large. If zero, then
7231 the size is approximated using silc_mp_sizeinbase, which however
7234 * Created Global RNG API which is global RNG that application can
7235 initialize. After initializing, any routine anywhere in the
7236 code (including library) can use RNG without allocating a new
7237 RNG object. This was done to allow this sort of use of the
7238 RNG in code that has no chance to allocate RNG object. All
7239 applications currently allocate this and many routines in the
7240 library use this. Affected file lib/silccrypt/silcrng.[ch].
7242 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7243 it to use the Global RNG API.
7245 * Defined Authentication Payload into protocol specification that
7246 is used during SILC session to authenticate entities. It is
7247 used for example by client to authenticate itself to the server
7248 to obtain server operator privileges.
7250 Implemented this payload into the lib/silccore/silcauth.[ch].
7251 Implemented also routines for public key based authentication
7252 as the new protocol specification dictates.
7254 Moved definitions of different authentication methods from
7255 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7257 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7258 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7259 silc_pkcs_verify_with_hash functions into the file
7260 lib/silccrypt/silcpkcs.[ch].
7262 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * The client entry's userinfo pointer must be always valid.
7265 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7266 will fail since it requires the userinfo. Now, the userinfo
7267 is allocated as "" if actual userinfo does not exist. Actually,
7268 it must exist and it is totally Ok to drop client connections
7269 that does not announce the userinfo. However, we will make
7270 this workaround for now.
7272 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7273 to return the remote port by socket.
7275 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7278 SILC_SERVER_PENDING_EXEC and added an new macro
7279 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7280 data or when error occurs while processing the pending command.
7282 Added new argument `destructor' into silc_server_command_pending
7283 and to the SilcServerCommandPending object. This destructor is
7284 now called after calling the pending callback or if error occurs
7285 immediately. If error occurs the actual pending callback won't
7286 be called at all - only the destructor. The destructor may be
7287 NULL if destructor is not needed.
7289 All this applies for client library code as well. Similar
7290 changes were made there as well for the pending commands.
7292 In the client, the application must now allocate the
7293 SilcClientCommandContext with the silc_client_command_alloc
7296 * Added reference counter to the SilcServerCommandContext. Added
7297 function silc_server_command_alloc and silc_server_command_dup
7300 Same type of functions added to the client library for the same
7303 * Removed the cmd_ident from IDListData away since it is now
7304 global for all connections. It is the command identifier used
7305 in command sending and with pending commands. The affected file
7308 * Added reference counter to the SilcSocketConnection objecet to
7309 indicate the usage count of the object. The object won't be
7310 freed untill the reference counter hits zero. Currently only
7311 server uses this, and client ignores it. The client must be
7312 set to use this too later. The affected files are
7313 lib/silccore/silcsockconn.[ch]. Added also the function
7314 silc_socket_dup to increase the reference counter.
7316 This was mainly added because it is possible that the socket
7317 is removed underneath of pending command or other async
7318 operation. Now it won't be free'd and proper DISCONNECTING
7319 flags, etc. can be set to avoid sending data to connection that
7320 is not valid anymore.
7322 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7323 the connection. After that it sets SILC_SET_DISCONNECTED.
7324 It is, however, possible that the socket data is not still freed.
7325 The silc_server_packet_process now checks that data is not
7326 read or written to connection that is DISCONNECTED. The socket
7327 get's freed when the reference counter hits zero.
7329 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Changed the client operation API: channel_message operation's
7332 `sender' is now the client entry of the sender, not the nickname
7333 and the `channel' is the channel entry, not the channel name.
7335 In the private_message operation the `sender' is now also the
7336 client entry of the sender not the nickname.
7338 Affected file is lib/silcclient/ops.h and all applications
7339 using the client operations.
7341 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Moved the calling of ops->connect() from connect_to_server_final
7344 into receive_new_id functin since that is the point when the
7345 client is actually allowed to send traffic to network. The
7346 affected file is lib/silcclient/client.c.
7348 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7351 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7352 (if needs broadcasting) instead of broadcasting the packets one
7353 by one which would make a burst in the network traffic.
7355 * Added `broadcast' argument to the functions in silcd/server.[ch]
7356 silc_server_create_new_channel[_with_id] to indicate whether
7357 to send New Channel packet to primary router.
7359 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added new function into the silcd/server.[ch] files:
7362 silc_server_create_new_channel_with_id to create new channel with
7363 already existing Channel ID.
7365 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7366 lib/silccore/silcpacket.h. This packet is used t send list of
7367 Set Mode payloads inside one packet. Server uses this to set
7368 the modes for the channels and clients on those channels, that it
7369 announced to the router when it connected to it. The protocol
7370 specification has been updated accordingly.
7372 * The silc_server_new_channel did not handle the packet coming
7373 from normal server as it normally does not send that. However,
7374 when it announces its channels it does send it. Implemented
7375 the support for that.
7377 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7378 into the file lib/silccore/id.h.
7380 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Fixed memory leaks in the functions silc_idlist_del_client,
7383 silc_idlist_del_channel and silc_idlist_del_server in the file
7384 silcd/idlist.c. All of those leaked like a sieve.
7386 * Fixed some small memory leaks in the client's function
7387 silc_client_notify_by_server.
7389 * Added functions into silcd/server.c: silc_server_announce_clients,
7390 silc_server_announce_channels and silc_server_announce_server.
7391 These functions are used by normal and router server to announce
7392 to its primary router about clients, channels and servers (when
7393 router) that we own. This is done after we've connected to the
7396 These functions effectively implements the following packet types:
7397 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7398 and SILC_PACKET_NEW_ID_LIST.
7400 * Added new functions into the silcd/packet_receive.[ch]:
7401 silc_server_new_id_list, silc_server_new_channel_list and
7402 silc_server_new_channel_user_list to handle the incoming
7403 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7405 * Added support of changing Channel ID in the function
7406 silc_server_replace_id. If the server that announces a channel
7407 to the router already exists in the router (with same name but
7408 with different Channel ID), router is responsible to send
7409 Replace ID packet to the server and force the server to change
7410 the Channel ID to the one router has.
7412 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7413 client that the Channel ID has been changed by the router. The
7414 normal server sends this to the client. Client must start using
7415 the new Channel ID as the channel's ID.
7417 Implemented handling of this new type into lib/silcclient/client.c
7418 into the function silc_client_notify_by_server.
7420 * Added new function silc_idlist_replace_channel_id into the files
7421 silcd/idlist.[ch] to replace the Channel ID.
7423 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Call silc_server_command_identify_check always when processing
7426 the IDENTIFY command in silcd/command.c
7428 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7430 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7431 send keepalive packets. The packet can be sent by clients,
7432 servers and routers.
7434 Added function silc_socket_set_heartbeat into the file
7435 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7436 If not set, the heartbeat is not performed. The actual
7437 heartbeat is implemented in the low level socket connection
7438 library. However, application is responsible of actually
7441 Added silc_server_send_heartbeat to send the actual heartbeat
7442 packet into silcd/packet_send.[ch]. Server now performs
7443 keepalive with all connections.
7445 * Added silc_task_get_first function into lib/silcutil/silctask.c
7446 to return the timeout task with shortest timeout. There was a bug
7447 in task unregistration that caused problems. TODO has been
7448 updated to include that task system must be rewritten.
7450 * The client library will now resolve the client information when
7451 receiving JOIN notify from server for client that we know but
7452 have incomplete information.
7454 * Rewrote parts of silc_server_remove_from_channels and
7455 silc_server_remove_from_one_channel as they did not remove the
7456 channel in some circumstances even though they should've.
7458 * Encryption problem encountered in server:
7460 The LEAVE command used to send the Channel Key packet to the
7461 router immediately after generating it. However, the code
7462 had earlier sent Remove Channel user packet but not immediately,
7463 ie. it was put to queue. The order of packets in the router
7464 was that Channel Key packet was first and Remove Channel User
7465 packet was second, even though they were encrypted in the
7466 reverse order. For this reason, MAC check failed. Now, this
7467 is fixed by not sending the Channel Key packet immediately but
7468 putting it to queue. However, this is more fundamental problem:
7469 packets that are in queue should actually not be encrypted
7470 because packets that are sent immediately gets encrypted
7471 actually with wrong IV (and thus MAC check fails). So, packets
7472 that are in queue should be encrypted when they are sent to
7473 the wire and not when they put to the queue.
7475 However, the problem is that the current system has not been
7476 designed to work that way. Instead, the packet is encrypted
7477 as soon as possible and left to the queue. The queue is then
7478 just purged into wire. There won't be any fixes for this
7479 any time soon. So, the current semantic for packet sending
7482 o If you send packet to remote host and do not force the send
7483 (the packet will be in queue) then all subsequent packets to the
7484 same remote host must also be put to the queue. Only after the
7485 queue has been purged is it safe again to force the packet
7488 o If you send all packets immediately then it safe to send
7489 any of subsequent packets through the queue, however, after
7490 the first packet is put to queue then any subsequent packets
7491 must also be put to the queue.
7493 Follow these rules and everything works fine.
7495 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Added new function silc_server_remove_clients_by_server to
7498 remove all client entries from ID list when the server connection
7499 is lost. In this case it is also important to invalidate all
7500 client entires as they hold the invalid server entry. This
7501 fixes fatal bug when server has lost connection and will reconnect
7504 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Made some sanity checks to silc_server_daemonise like to check
7507 whether the requested user and group actually exists.
7509 * Added sanity check to SKE's silc_ske_responder_finish to check
7510 that the public and private key actually is valid.
7512 * Invalidate the client's nickname when receiving Replace ID
7513 packet and the Client ID is being replaced. This means that the
7514 server will query the nickname if someone needs it (client)
7517 * Sort the ID Cache in client library when the ID Cache data
7518 has changed (needs sorting).
7520 * Do not allow for SILC client to create several connections to
7521 several servers. The client does not support windows right now
7522 and generating multiple connections causes weird behaviour.
7524 Irssi-silc client does support windows and can handle several
7525 connections without problems, see: www.irssi.org and SILC plugin.
7527 * Fixed some places where client was added to the IDList. The
7528 rule of thumb is following (in order to get everything right):
7529 If the client is directly connected local client then the
7530 `connection' argument must be set and `router' argument must be
7531 NULL to silc_idlist_add_client function. If the client is not
7532 directly connected client then the `router' argument must
7533 bet set and the `connection' argument must be NULL to the
7534 silc_idlist_add_client function.
7536 * The funtion silc_server_packet_send_local_channel actually did
7537 not check whether the client was locally connected or not. It
7538 does that now. Fixed a bug related to LEAVE command.
7540 * Fixed Remove Channel User payload parsing bug in server's
7541 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7543 * The server's silc_server_save_channel_key now checks also the
7544 global ID list for the channel as it might not be in the local
7545 list. Fixed a bug related to LEAVE command.
7547 * Is this the end of the [<unknown>] buglet that has been lurking
7548 around for a long time? A little for loop fix in server's
7549 silc_server_command_whois_parse that is used by both IDENTIFY
7550 and WHOIS command. At least, this was a clear bug and a cause
7551 of one type of [<unknown>] buglet.
7553 * WHOIS and IDENTIFY commands call the function
7554 silc_server_command_[whois/identify]_check function even if
7555 we are not router server.
7557 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Added --with-gmp configuration option. If set the GMP
7560 is always compiled in the SILC source tree. If not set then
7561 it is checked whether the system has the GMP3 installed. If
7562 it has then the GMP won't be compiled (the system's headers
7563 and library is used), if it doesn't have it then the GMP is
7564 compiled in the SILC source tree.
7566 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7568 * Changed RSA private exponent generation to what PKCS #1
7569 suggests. We try to find the smallest possible d by doing
7570 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7571 not security fix but optimization.
7573 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Added new config entry [Identity] to fork the server and run
7576 it as specific user and group. A patch from Bostik.
7578 * Imported Dotconf configuration library into lib/dotconf.
7579 This will be used to create the SILC configuration files later.
7580 It will appear in the distsribution after this commit.
7582 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * A big code auditing weekend happening. Auditing code for
7585 obvious mistakes, bugs and errors. Also, removing any code
7588 Removed files for being obsolete:
7590 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7591 inline in the file lib/silcutil/silcbuffer.h)
7593 o lib/silcutil/silcbufutil.c (the header has inline versions)
7595 Changed code to fix possible error conditions:
7597 o The buffer formatting routines now check that the destination
7598 buffer really has enough space to add the data. This applies for
7599 both buffer formatting and unformatting
7600 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7601 unformatting was changed to accomodate following rules:
7602 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7603 sent to the function while XXX_*STRING will not allocate or copy
7604 the data into the buffer. Instead it sets the pointer from the
7605 buffer into the pointer sent as argument (XXX_*STRING used to
7606 require that the pointer must be allocated already). This change
7607 makes this whole thing a bit more consistent and more optimized
7608 (note that the data returned in the unformatting with XXX_*STRING
7609 must not be freed now). The routines return now -1 on error.
7611 o Tried to find all code that use buffer_format and buffer_unformat
7612 and added return value checking to prevent formatting and
7613 especially unformatting errors and possible subsequent fatal
7616 o Changed ske->x and ske->KEY to mallocated pointers in
7617 lib/silcske/silcske.h. Fixed possible data and memory leak.
7619 o Added return value checking to all *_parse* functions. Fixed
7620 many memory leaks as well.
7622 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7623 so that buffer overflows would not happen. All code now also
7624 checks the return value as it can fail.
7626 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Added reconnection support to server if the normal server looses
7629 its connection to the router (for example if router is rebooted).
7630 The server performs normal reconnection strategy implemented
7631 to the server. Affected file silcd/server.c.
7633 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7635 * Added new packet type SILC_PACKET_SET_MODE that is used to
7636 distribute the information about changed modes (for clients,
7637 channels and clients channel modes) to all routers in the
7638 network. Updated the protocol specification accordingly.
7640 Added functions into silcd/packet_send.c and
7641 silcd/packet_receive.c: silc_server_send_set_mode,
7642 silc_server_set_mode.
7644 Added new files silcmode.[ch] into lib/silccore that implements
7645 the encoding and decoding of Set Mode Payload. Added new type
7646 SilcSetModePayload. Moved the definitions of different modes
7647 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7649 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * Oops, a little mistake in server's connection authentication
7652 protocol. The protocol is not ended with FAILURE but with
7653 SUCCESS if the authentication is Ok. :) Affected file is
7656 * Implemented NICK_CHANGE notify handling in server in the file
7657 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7658 the local clients on the channel. After the changing nickname
7659 in router environment snhould work and the [<unknown>] nickname
7660 should appear no more.
7662 The silc_server_replace_id function that receives the Replace ID
7663 payload now sends the NICK_CHANGE notify type also in the file
7664 silcd/packet_receive.c
7666 * Changed WHOIS and IDENTIFY command to support the maximum amount
7667 of arguments defined in protocol specs (3328 arguments). This
7668 fixed a bug that caused problems when there were more than three
7671 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Added extra parameter, command identifier, to the
7674 silc_client_send_command so that explicit command identifier
7677 Changed that ID list routines uses specific command identifier
7678 when sending WHOIS/IDENTIFY requests to the server so that they
7679 can be identified when the reply comes back.
7681 Affected files lib/silcclient/command.[ch],
7682 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7684 * Added `sender' argument to silc_server_packet_send_to_channel
7685 to indicaet the sender who originally sent the packet to us
7686 that we are now re-sending. Ignored if NULL. Affected file
7687 silcd/packet_send.[ch].
7689 * Added some server statistics support in silcd/server_internal.h
7690 SilcServerStatistics structure and around the server code. Also
7691 send some nice statistics information when client is connecting
7694 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Fixed channel ID decoding in server's JOIN command reply in
7697 silcd/command_reply.c
7699 * Fixed braodcasting of replace ID payload to not to send it if
7700 we are standalone server in silcd/packet_receive.c.
7702 * Fixed all channel message sending routines to not to send
7703 packets to clients that has router set, since they are routed
7704 separately in the same function earlier. Affects file
7705 silcd/packet_send.c and all channel packet sending functions.
7707 * In USERS reply, res_argv[i] are not allocated, the table
7708 is allocated. Thus changed that free the table, not its
7711 * In server's whois_check and identify_check if the client is
7712 locally connected do not send any WHOIS commands - they are not
7715 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7717 * Fixed some minor bugs in client when sending WHOIS command. The
7718 arguments was in wrong order.
7720 * Removed statis function add_to_channel from server in
7721 silcd/command.c that was previously used with the joining but
7724 * Tested USERS command in router environment successfully with two
7725 routers, two servers and two clients.
7727 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Reorganized the USERS command and command reply in client library
7730 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7731 When the command is given by user we register a pending command
7732 callback that will reprocess the command after the reply has been
7733 received from the server. When reprocessing the packet we then
7734 display the information. Thus, the USERS information is displayed
7735 now in the command callback instead of in the command reply
7736 callback. The processing of the command is same as previously
7737 when server has sent the command reply in the JOINing process.
7739 * Added to USERS command in silcd/command_reply.c to join the client,
7740 we didn't use to know about, to the channel after we've created
7741 a client entry for it. Also, for clienet we did know already still
7742 check whether it is on the channel or not and add it if not.
7744 * Removed silc_server_command_join_notify as the function and its
7747 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Changed the client's pending command handling to the same as the
7750 server's pending command handling. It is also now possible to
7751 execute command reply functions from other command reply
7752 function as the function callbacks for commands and command
7753 replies are one and same. The pending commands are not static
7754 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7755 in client connection context. Thus, pending commands are server
7756 connection specific as it is convenient.
7758 Changed the function silc_client_command_pending and
7759 silc_client_command_pending_del and added new function
7760 silc_client_command_pending_check. Removed the
7761 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7764 * Added cmd_ident, current command identifier, to the client
7765 connection context in lib/silcclient/client.h to keep track on
7766 command identifiers used in command sending. Client's command reply
7767 function handling now supports the mandatory command identifiers.
7769 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7770 funtions in client to fully support pending command callbacks.
7772 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7773 as one of the arguments to the application in the command reply
7776 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7777 before first releasing SILC but came back. Now it is removed again
7778 and should come back nomore. The FORWARDED flag was used only
7779 by the JOINing procedure by forwarding the command packet to router.
7780 Now, the JOINing procedure has been changed to more generic (due
7781 to various router environment issues) and FORWARDED is not needed
7782 anymore for anything. The protocol specification is yet to be
7785 Now, removed silc_server_packet_forward from server and the flag
7786 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7788 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7790 * Renamed NAMES command to USERS command. The NAMES was named that
7791 due to historical reasons. Now it is renamed. Also, rewrote
7792 parts of the USERS command. The nickname list is not sent anymore
7793 by the server. Only Client ID and mode lists are sent in the USERS
7794 command. Changed this also to the protocol specification.
7796 The client now resolves the names and stuff after it receives
7797 the USERS list from the server when joining to the channel.
7799 * WHOIS and IDENTIFY commands has been changed to support multiple
7800 Client ID's per command. One can now search for multiple users
7801 in the network by sending only one WHOIS or IDENTIFY command.
7802 Changed the code and the protocol specifications.
7804 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7805 uses silc_server_command_whois_parse to parse the request. */
7807 * If normal server, do not parse the WHOIS and IDENTIFY requests
7808 before sending it to the router. Saves some time.
7810 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Fixed JOIN command on client library. Wrong number of arguments
7813 used to crash the client.
7815 * Added silc_server_channel_has_global function to check whether
7816 channel has global users or not.
7818 * Added silc_server_channel_has_local function to check whether channel
7819 has locally connected clients on the channel.
7821 * The silc_server_remove_from_one_channel now checks whether the
7822 channel has global users or not after given client was removed from
7823 the channel. It also checks whether the channel has local clients
7824 on the channel anymore. If it does not have then the channel entry
7825 is removed as it is not needed anymore.
7827 * The silc_server_notify now checks on JOIN notify whether the joining
7828 client is one of locally connected or global. If it is global then
7829 the channel has now global users on the channel and that is marked
7830 to the channel entry. Also, it now saves the global client to
7831 global list who is joining and JOINs it to the channel. This is
7832 for normal server, that is.
7834 Changed silc_server_send_notify_on_channel,
7835 silc_server_packet_relay_to_channel and
7836 silc_server_packet_send_to_channel check if we are normal server
7837 and client has router set (ie. global client) do not send the
7838 message to that client, as it is already routed to our router.
7840 * Implemented LEAVE notify type handling in silc_server_notify
7843 * Tested LEAVE command in router environment successfully. Tested
7844 with two routers, two servers and two clients.
7848 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7850 * Implemented SIGNOFF notify type handling in silc_server_notify
7853 * silc_server_remove_id now removes the client entry from all channels
7854 it has joined and thusly sends SIGNOFF notify type.
7856 * Rewrote the NAMES list generation in server by removing two excess
7857 loops. The lists are created now inside one loop.
7859 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7861 * silc_server_remove_channel_user checks now also global list
7862 for channel and client.
7864 * silc_server_new_channel_user checks now both local and global
7865 list for channel and client. Fixed a bug in client id decoding.
7866 Used to decode wrong buffer.
7868 * silc_server_channel_message checks now both local and global
7869 list for channel entry.
7871 * Tested channel joining (hence JOIN) in router environment
7872 successfully. Tested with two routers, two servers and two
7875 * Tested channel message sending in router environment successfully.
7877 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * Added silc_server_save_channel_key into server.[ch] to save the
7880 received channel key in Channel Key payload processing. It is
7881 also used in JOIN command reply handling.
7883 Equivalent function silc_client_save_channel_key added into
7884 client.[ch] into client library.
7886 * Changed JOIN command reply to send information whether the channel
7887 was created or not (is existing already) and the channel key
7888 payload. Changed protocol specs accordingly.
7890 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7891 the request was sent by ID and not by nickname. Crashed on
7894 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7897 now correctly save the received data.
7899 * silc_server_free_sock_user_data now notifies routers in the
7900 network about entities leaving the network.
7902 At the same time implemented functions silc_server_remove_id
7903 and silc_server_send_remove_id to receive and send REMOVE_ID
7904 packets. The packet is used to notify routers in the network
7905 about leaving entities. The ID removed will become invalid in
7908 * Added function silc_idlist_del_server into server. Removes and
7909 free's server entry from ID list.
7911 * silc_server_private_message function now checks, if we are router,
7912 that the destination ID really is valid ID, naturally.
7914 * In router when NEW_ID packet is received (for new client) the
7915 hash of the Client ID is saved in the ID Cache but the
7916 client->nickname is set to NULL, instead of putting the hash
7919 IDENTIFY command now also checks that client->nickname must be
7920 valid. If it is not if will request the data from the server who
7921 owns the client. Added new function
7922 silc_server_command_identify_check.
7924 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7925 to set the command to already allocated Command Payload.
7927 * Tested private message sending in router environment with two
7928 routers, two servers and two clients. Fixed minor bugs and now
7931 * Fixed segfault from client's NAMES command. Used to crash if
7934 * Forwarded packets must not be routed even if it is not destined
7935 to the receiver. Changed server code comply with this.
7937 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7939 * Added `require_reverse_mapping' boolean value to ServerParams
7940 structure. If TRUE (not default) the server will require that
7941 the connecting host has fully qualified domain name.
7943 If the reverse mapping is not required and hostname could not be
7944 found the IP address is used as hostname.
7946 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7948 * Implemented version string checking to both client and server.
7949 The check is incomplete currently due to the abnormal version
7950 strings used in development version of SILC.
7952 * Changed all command functions in server to use the new
7955 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7957 * Changed char *data to unsigned char *data in ID Cache system to
7958 support binary data as ID Cache data. Changed code to support
7959 binary data in lib/silccore/idcache.c.
7961 * Renamed silc_server_packet_relay_command_reply to
7962 silc_server_command_reply as it is normal packet receiving
7963 function. Rewrote the function to accept command replys for
7964 servers and not only for clients.
7966 * Mark remote router always as registered server if we are connecting
7967 to it. Otherwise, commands sent by the router to us are ignored.
7969 * All ID List find routines now returns the ID Cache Entry pointer
7970 as well if requested.
7972 * WHOIS command works now in router environment, tested with two
7973 routers, two servers and two clients.
7975 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7976 in router environment (as it is almost equivalent to WHOIS) but
7977 hasn't been tested thoroughly. Added new functions:
7979 silc_server_command_identify_parse
7980 silc_server_command_identify_send_reply
7981 silc_server_command_identify_from_client
7982 silc_server_command_identify_from_server
7984 * Disabled route cache adding because adding two different ID's with
7985 same IP replaces the old cache entry thus giving wrong route.
7986 The entry->router->connection is always the fastest route anyway
7987 so route cache may not be needed. Of course, new routes maybe
7988 established after receiving the ID when the entry->router->connection
7989 might not be anymore the most optimal.
7991 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7993 * Add route cache for received ID for fast routing.
7995 * Added silc_server_packet_route to route received packet on router
7996 that is not destined to us.
7998 * Renamed silc_server_get_route to silc_server_route_get.
8000 * Added id_string and id_string_len fields into SilcServer to
8001 include encoded ServerID for fast comparing without excess
8002 encoding of the ID's.
8004 * Cleaned up WHOIS command on server side. Added following static
8007 silc_server_command_whois_parse
8008 silc_server_command_whois_check
8009 silc_server_command_whois_send_reply
8010 silc_server_command_whois_from_client
8011 silc_server_command_whois_from_server
8013 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8014 arguments in command replies. All command functions should be
8015 updated to use this macro.
8017 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Minor typo fixes on command reply handling on server.
8021 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * Added silc_server_command_add_to_channel internal routine to add
8024 the client to the channel after router has created the channel and
8025 sent command reply to the server.
8027 * Added generic silc_server_send_command to send any command from
8030 * Use static buffer with ID rendering instead of duplicating data.
8032 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8034 * Fixed a channel user mode bug when joining to a channel server gave
8035 everybody channel founder rights, oops.
8037 * We mark ourselves as the router of the incoming server connection
8038 if we are router ourselves. This way we can check in some packet
8039 sending functions whether it is locally connected server. For
8040 incoming router connections we put NULL.
8042 * For router sending packets locally means now always sending the
8043 packet cell wide; to local clients and local servers. For normal
8044 server sending packet locally means sending it to only local
8047 * Fixed the JOIN command to really work in router environment. If the
8048 channel is created it is always created by the router. Router is
8049 also responsible of making the initial joining to the channel,
8050 sending JOIN notify to the sending server and distributing
8051 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8052 does not exist server doesn't do anything else but forward the
8053 command to the router which performs everything.
8055 * Added silc_server_send_channel_key function to send the Channel Key
8058 * Added silc_server_create_channel_key to create new channel key. The
8059 channel key is now re-generated everytime someone joins or leaves
8060 a channel, as protocol dictates. Note: channel->key_len is the
8063 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8065 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8066 packet_receive.[ch] to separate packet sending and receiving
8067 routines. The server.[ch] now includes everything else including
8068 actual packet processing (writing and reading data) and other
8071 Renamed silc_server_private_message_send_internal to
8072 silc_server_send_private_message. The routine is still though
8073 used only to relay private messages as server does not send
8074 private messages itself.
8076 Renamed silc_server_new_channel to silc_server_create_new_channel
8077 and added new function sicl_server_new_channel that handles the
8078 incoming New Channel packet. Added also new sending function
8079 silc_server_send_new_channel to send New Channel Payload.
8081 * Added new function silc_server_notify to process incoming notify
8082 packet to the server/router. Server may then relay the notify
8083 to clients if needed.
8085 * Added new function silc_server_new_channel_user to process incoming
8086 New Channel User packet. Router will redistribute the packet and
8087 send JOIN notify to its local clients and locally connected servers
8088 if needed. Normal server will send JOIN notify to its local client
8089 on same channel when received this packet. Added also corresponding
8090 sending function silc_server_send_new_channel_user to sent the
8093 * Added boolean route argument to send_notif_to_channel and
8094 packet_send_to_channel functions to attempt to route the packet
8095 if it is TRUE and send only locally if it is FALSE.
8097 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8099 * silc_server_replace_id now broadcasts the received replace ID
8100 packet if it is not broadcast packet already. The router must
8101 broadcast to inform other routers about changed ID.
8103 * Added backpointer to server's router into SilcServer context in
8104 silcd/server_internal.h.
8106 * Fixed silc_server_packet_broadcast to send correct broadcast
8109 * The channel key is now distributed to the local client as soon
8110 as it is received from the router (in router environment) so that
8111 no other packet may be sent for the channel until client has
8114 * silc_server_remove_channel_user now broadcasts the received
8115 Remove Channel User packet if it is not broadcast packet already.
8116 The router must broadcast to inform other routers about removed
8119 * Added users field into SilcPacketContext that is a reference count
8120 of the context. One can increase the reference count by calling
8121 silc_packet_context_dup which is now changed to just increase the
8122 reference count instead of duplicating the data. The reference
8123 count is decresed by calling silc_packet_context_free that will
8124 free the data after the reference count hits zero.
8126 For now on the packet context and everything allocated into it
8127 (including the raw packet from network) must be freed by calling
8128 the new silc_packet_context_free function. Added also new function
8129 silc_packet_context_alloc that must be used now to allocate the
8130 context. This also means that if a routine is asynchronous from
8131 silc_[client/server]_packet_parse_type the packet context must
8132 be duplicated by calling silc_packet_context_dup. Otherwise it
8133 gets free'd after silc_[client/server]_packet_parse_type returns.
8134 Also, one must remember that if packet is duplicated then its
8135 reference count must be decresed by calling the free function as
8136 many times as it was duplicated.
8138 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8139 from both client and server.
8141 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8143 * Made joining to a channel working in router environment.
8145 * Cleaned up JOIN command on server side and create function
8146 silc_server_command_join_channel internal routine to make the
8149 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8151 * Changed silc_command_pending list to SilcDList. Also, added
8152 `ident' field to SilcServerCommandPending structure to identify
8153 the reply and to call correct callback.
8155 Added silc_server_command_pending_check function to replace the
8156 corresnponding macro. The silc_command_pending list is not
8159 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8160 to set identifier to previously allocated Command Payload. It
8161 is used to set identifier for command when resending Command
8164 * Added silc_command_payload_encode_payload to encode Command
8165 Payload buffer from SilcCommandPayload structure.
8167 * Added silc_argument_payload_encode_payload to encode Argument
8168 payload buffer from SilcArgumentPayload structure.
8170 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Changed WHOIS command to support router connection on server side.
8173 The whois request is always sent to router unless the server is
8174 standalone server. After server has received the reply from the
8175 router will it send the reply to the client.
8177 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8178 broadcast received broadcast packet. The function is used only
8179 by router. The broadcast packet is always sent to the router's
8182 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8183 render given ID to printable string, for log files for example.
8185 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Made basic router to router connections working. At least they
8188 can now connect to each other but nothing really works the way
8189 they are supposed - yet.
8191 * Added new initiator token to RouterConnection configuration
8192 file in silcd/serverconfig.[ch]. It is used to tell whether we
8193 are the initiator to the remote router or whether we'll expect
8194 the other end to connect.
8196 * Moved registering of listener task to silc_server_init, hence
8197 the server starts listenning as soon as it is run, even if it
8198 does not have connections to other routers. Let's see how well
8201 * Changed default connection retry timeouts for more suitable in
8204 * Removed cipher and such arguments from silc_idlist_add_client
8205 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8206 Added new function silc_idlist_add_data to add the keys and stuff
8209 * Added SilcIDListData structure and added it to SilcClientEntry
8210 and SilcServerEntry as their first field in the structure. This
8211 way we can explicitly cast the ID entries to the SilcIDListData
8212 structure and get common data for the entries. In past, we had
8213 to first check what type of connection it is and then cast it to
8214 correct ID entry type. Now, we can directly cast the opaque
8215 pointer to the SilcIDListData (no matter what ID entry it actually
8216 is) and get the data needed.
8218 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8221 in some circumstances even if threre were timeout tasks, though not
8222 IO tasks, but tasks anyway. Now fixed.
8224 * Defined SilcServerConnection structure to hold connection specific
8225 stuff about directly connected servers and routers. The definition
8226 is currently in silcd/server_internal.h. I thought about having
8227 a bit more important role fro this struct but for now it is used
8228 only when connecting to other server (or router actually).
8230 * Added connecting retry support in server when connecting to
8231 router(s). The retry feature implement exponential backoff
8232 algorithm. Also, added SilcServerParams structure to hold default
8233 parameters for server. For now, it include these retry settings
8234 and are hard coded. After server is moded to be as Silc Server
8235 Library this structure will be more important.
8237 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8239 * Changed client librarys channel->clients table to SilcList and
8240 changed code accordingly.
8242 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8244 * Changed client's channel table to SilcList and changed code
8245 accordingly. Also changed SilcChannelClientEntry to include back-
8246 pointer to the channel so that client entry can use that structure
8247 as list as well and we have fast cross-reference to the channel.
8248 This change dramatically decreased the complexity of channel
8249 handling with client entry and vice versa (removed one extra
8250 loop when searching for channel entry from many functions).
8252 * Changed server->sim from table to SilcDList and changed code
8255 * NAMES command can now be used from user interface. It will show
8256 the user list on the channel, neatly.
8258 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8259 Code now saves realname of the user if it becomes available.
8261 * Renamed configure.in to configure.in.pre and made ./prepare
8262 script to automatically add correct version string to
8263 configure.in which it creates from configure.in.pre.
8265 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * NAMES command reply now shows users mode with the nickname when
8270 * Moved silc_client_ch[u]mode[_char] functions from
8271 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8272 place sucks, they are utility functions and should be in some
8275 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8277 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8280 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8284 * Added TRQ (efficient deque and list library) into lib/trq. This is
8285 a very good list library that is currently used in the SILC. Defined
8286 SilcList API over the library because I didn't like the API very
8287 much. See lib/trq/silclist.h for the API and examples of how to
8288 use the API. Fixed various places in the code to use the new
8289 SilcList API. The SilcList is meant for lists that has a structure
8290 already defined as a list. It is not suitable to add just some
8291 context to the list (in TRQ, the context is the list actually).
8293 So, I defined SilcDList that can be used for the purpose where
8294 predefined list structure does not exit. This can be used as
8295 such list. Now some context just can be added to the SilcDList.
8296 Currently this list is not used in the SILC just yet, though there
8297 are a lot places where this can replace dynamically allocated
8298 tables and I will fix these places, later, to use SilcDList.
8299 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8300 and use TRQ internally).
8302 Also fixed some annoying warning messages that the original TRQ
8303 code generated. Also minor changes to TRQ's Makefile.in.
8305 * Added support for querying by Client ID to both WHOIS and
8306 IDENTIFY commands into server, as required by the protocol.
8308 * Removed method function pointers from SilcBuffer structure. They
8309 weren't used to anything and just increased the context size for
8310 no good reason. This change also made silc_buffer_alloc and
8311 silc_buffer_free functions inline functions.
8313 * Disabled command flooding detection support until it's fixed so
8314 that it accepts commands in but does not execute them more than once
8317 * Added silc_net_localhost(), to return local hostname, into
8318 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8319 that must be initialized before calling silc_client_init.
8321 * Added new function: silc_server_send_notify_on_channels to send
8322 notify messages to all channels client has joined. It is assured
8323 that the message is sent only once per client.
8325 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8326 lib/silcutil/silcutil.[ch] as silc_format function. The new
8327 function is generic and is used by server as well, not only by
8328 the logging routines.
8330 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8331 the provided version string was not acceptable. Added new function:
8332 silc_ske_check_version into lib/silcske/silcske.h. The function
8333 must be implemented by the application (client or server) and it
8334 does not reside in the SKE library. The function checks the version
8335 string remote end sent.
8337 * Added back pointers (to opaque context and to SilcSocketConnection)
8338 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8340 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8341 duplicate packet context structure.
8343 * Changed `notify' client operation to send same arguments as client
8344 receives from server except for ID's. ID's are mapped to correct
8345 ID entry and that is returned. Also, if channel entry is not sent
8346 by server but the notify is for channel the channel entry is sent
8347 to application (otherwise application doesn't know that it is for
8348 channel (library gets it from packet's Destination ID)).
8350 * Added silc_client_remove_from_channels into client library to
8351 remove a client from all channels it has joined to. Used when
8352 received SIGNOFF notify from server. Added also new function
8353 silc_client_replace_from_channels to replace old ID entry with
8354 new ID entry on all channels. Used when received NICK_CHANGE
8357 * Fixed ID Cache list handling in silc_idlist_get_client in
8358 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8359 to get (or query) client by ID.
8361 * Updated TODO list.
8363 * Added connection authentication status message defined by the
8364 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8365 support for these into the code in client and server side.
8367 * Added generic function silc_client_send_command to send any command
8368 with variable argument list. Application should use this function
8369 to send commands if the command functions provided by the library
8370 does not suite for the application's user interface needs.
8372 * Added new `failure' client operation. Application is notified about
8373 received failure packet if client is executing a protocol. In this
8374 case the protocol's execution has failed.
8376 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8377 is required by the protocol.
8379 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8380 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8383 * Added status flag to SilcSKE object to indicate realtime status
8384 of the SKE protocol.
8386 * Application receives now exactly same command reply arguments as
8387 the library receives from server. However, if ID is received the
8388 corresponding ID entry is returned to the application (eg. Client
8389 ID is mapped to correct SilcClientEntry entry and that is returned).
8390 Changed command_reply client operation due to this change.
8392 * Changed all ID's in commands and in command replys as ID Payloads.
8393 Change affected both client and server side codes.
8395 All ID's sent in SILC network (with execption of ID's in SILC
8396 Packet header) are sent in ID Payload to support variable length
8399 * Server now notifies nick changes and notifies all clients on
8400 the channels about the new nickname (about the new Client ID,
8403 * Implemented CMODE command to change channel modes. Supports all
8404 channel modes defined by the protocol specs except ban and invite
8405 lists. (Also, private channel key mode is supported but support for
8406 setting private channel key in client is missing, thus, this mode
8407 has no effect on client side (except that server requires that the
8408 client uses private channel key and normal channel traffic does not
8411 Also, invite mode works per se, but INVITE command does not work
8412 yet correctly, so you can set channel as invite only channel but
8413 inviting clients to the channel does not work (it is yet to be
8414 thought what's the best way to do it).
8416 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8417 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8418 Implemented CUMODE command to change user's mode on the channel.
8419 Supports all modes defined by the protocol specs.
8421 * Added NAMES command reply to return users modes on the channel.
8423 * Removed unnecessary and slow ciphers from lib/silccrypt.
8425 * Set SO_KEEPALIVE option to connection sockets by default.
8427 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8429 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8430 redefined the Notify Payload into protocol specs.
8432 * Added silc_id_payload_parse_id to get ID directly from raw
8435 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8438 accept searching by Client ID as well.
8440 * Added support for LEAVE and SIGNOFF notify types in client library.
8442 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8443 to parse ID Payload from raw data.
8445 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8447 * Added flags parameter into silc_ske_assemble_security_properties
8448 function in lib/silcske/silcske.[ch].
8450 * Changed notify client operation to fit better for notify messages
8451 sent by server. The notify payload received from server is now
8452 passed to the application (after parsing it to SilcNotifyPayload).
8453 It is application's responsibility to retrieve the arguments
8454 from the payload and show the message the way it wants. The message
8455 sent by server is implementation specific.
8457 * Changed public keys to comply with the protocol specification.
8458 Old public keys are not supported anymore and are not compatible.
8460 * Removed nickname from Channel Payload as the latest draft removed
8461 it. The client must resolve the nickname from the NAMES command
8462 reply received when it joined the channel.
8464 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8466 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Fixed some errors in protocol specification drafts.
8470 * Created lib/silccore/silcnotify.c to implement Notify Payload
8471 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8472 generic payloads described by protocol specifications. The file
8473 includes implementations for ID Payload and Argument Payload.
8475 * Changed Command Payload implementation to use the new Argument
8476 Payload. Changed command_xxxx_payload to command_payload_xxxx
8477 to comply with SILC coding conventions.
8479 * Added suppport for Argument Payload handling in Notify Payload
8480 implementation as protocol requires it. Added the new support
8481 into server and client lib as well.
8483 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8485 * Added support for multiple nicknames on same channel. [n] is
8486 added locally to the nickname if there are more than one same
8487 nicknames on the channel.
8489 * Server now sends all nicknames that matched WHOIS request.
8490 Client also shows the list received from server.
8492 * Added TOPIC command to client side. User can now set and show
8493 current topic on channel.
8495 * Added MOTD command to client and server. Also, server sends the
8496 motd when client connects to the server.
8498 * Changed version strings to comply ISO 8601.
8500 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8502 * Fixed protocol error handling in client library. It should now
8503 cope even if the SKE fails for some reason.
8505 * Made new protocol specification drafts for submitting to IETF.
8507 * Implemented TOPIC command to server in silcd/command.c.
8509 * Added two new notify types into lib/silccore/silcnotify.h:
8510 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8511 notify nickname change and topic setting/change on a channel.
8513 * API change of command_reply operation in client library. The
8514 application gets now the status type received from server as well.
8516 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8518 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8520 * Cras fixed and optimized the packet handling even further and
8521 it should work now. Minor change to the prototype of function
8522 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8524 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8526 * Added new function into lib/silcutil/silcschedule.[ch]:
8527 silc_schedule_with_fd to select() a specified fd. The function
8528 returns after timeout expires or data arrives or goes. The
8529 function is used by packet routines to wait that all data is
8530 received from network.
8532 * Fixed data reading from network in lib/silccore/silcpacket.c.
8533 The code now assures that all data is read from the fd and then
8534 continues packet processing. This was a bug fix since the code
8535 used to drop some data in some circumstances.
8537 * Added new function into lib/silcclient/client.[ch]:
8538 silc_client_start_key_exchange to start key exchange after
8539 connection has been established to server. The code internally
8540 now uses this funtion but its main purpose was to provide it
8541 for applications that perform their own connecting. After
8542 application has created a connection it merely calls this
8543 function to start the key exchange between client and server.
8544 The library takes care of everything else after that.
8546 Updated also lib/silcclient/README to explain the usage of
8549 * Do not send to application information that connection has
8550 been established. Application gets notified it by connect
8553 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8555 * Applied cras's patch to add silc_schedule_one function. The
8556 function runs scheduler once and returns.
8558 * Fixed the scheduler after cras messed it up. The timeout
8559 handling works now as it's supposed to work.
8561 * Added into lib/silccore/ silcnotify.h to include notify
8562 message types support. Changed silc_server_send_notify*
8563 functions, in server.[ch], to support those new notify types.
8564 Added the support for the notify types into client library,
8565 as well. Added new notify client operation into ops.h in
8568 * Changed silc_server_packet_send_to_channel to send normal
8569 packets instead of just channel message packets. The function
8570 is now used to send the notify packets to channels. It is not
8571 used to send channel message packets anymore, as server never
8574 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8575 va_arg()s as it seems to require it nowadays. I guess, if SILC
8576 is compiled with older va_arg() the new code should work anyway.
8578 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8580 * Splitted core library. Core library (lib/silccore) includes
8581 now only SILC protocol specific core (and common) components.
8582 Created new utility library (lib/silcutil) that includes more
8583 generic purpose stuff. The stuff for util library was taken
8584 from the old core library. This was minor and easy split.
8586 * Created SILC Client Library (lib/silcclient) that includes
8587 implementation of the SILC client without user interface. This
8588 was major move from silc/ directory. The code has been changed
8589 so that it is transparent towards the user interface. The
8590 silc/ directory includes now the same user interface as before
8591 and it uses the new client library. Read lib/silcclient/README.
8592 Basicly, the client library performs everything else related
8593 to SILC except user interface handling. Also, configuration
8594 files are considered to be part of user interface and library
8595 does not handle them.
8597 This change also changed a lot of structures, function naming etc.
8598 Most important change was that SilcClientWindow object was
8599 renamed to SilcClientConnection in the client library. Created
8600 also new file lib/silcclient/ops.h. Also added new files
8601 silc/local_command.[ch] and silc/client_ops.[ch].
8603 All these changes were made to make it easier for user interface
8604 designers to create what ever user interface for the SILC client
8607 It is also expected that the server will be moved to lib
8608 directory as well and SILC Server Library will be created;
8609 sometimes in the future.
8611 * Removed Local commands from lib/silccore/silccommand.h as
8612 they are application specific and new client library does not
8613 handle any of those anymore.
8615 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8616 old client implementation in silc/.
8618 * Added support for callback functions in SILC_LOG_* macros.
8619 Application can now set its own callbacks that will be called
8620 instead of using the default functions that will always print
8621 the debug messages to stderr (or stdout). Also, debugging can
8622 now be disabled by setting silc_debug to FALSE and re-enabled by
8623 setting it to TRUE. Note, that logging will still work even
8624 if debugging is disabled.
8626 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8627 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8628 silc_log_reset_debug_callbacks.
8630 * To enable debugging in silc client one must give now -d
8631 option on command line.
8633 * Changed silc_schedule_init to automatically allocate task queues
8634 if they are not allocated before calling it.
8636 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8638 * Added GMP 3.1 into math library.
8640 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8642 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8643 a channel in SILC network. The packet is used by servers and
8644 routers to notify other routers that user has left a channel.
8645 This little feature was missing until now. Added the feature
8646 to protocol specification as well.
8648 Added functions: silc_server_send_remove_channel_user and
8649 silc_server_remove_channel_user into server.[ch].
8651 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8652 lib/silccore/silcpacket.h. However, they are not implemented
8655 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8657 * Fixed joining to a channel and sending channel messages
8658 between server and router. The channel message sending should
8659 now work inside a cell.
8661 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8663 * Fixed the private message sending between server and router.
8664 The private message sending should now work inside a cell.
8666 * Added silc_server_replace_id into server.[ch] to replace
8667 existing ID in the SILC network.
8669 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8670 and silc_idlist_replace_server_id into idlist.[ch] in server.
8672 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8674 * Fixed the server to server connections. Server can again now
8675 connect to router. Router to router connections probably does
8678 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8680 * Added dynamic protocol registering support. Now protocols can
8681 registered and unregistered on the fly. Patch by cras.
8683 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Added lib/contrib directory to hold routines that some platforms
8686 don't have but are needed by SILC.
8688 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8689 into lin/contrib to provide getopt() and getopt_long() for
8690 those who don't have it.
8692 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8694 * Added AWAY command to client. When away message is set and
8695 client receives a private message packet the client automatically
8696 replies to the sender with the away message.
8698 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8699 bug seemed to be the cause of recent problems when compiling
8702 * Added version detection support to SKE protocol specification
8703 and added the new changes to the SKE implementation as well.
8704 There were other minor changes in the SKE protocol as well.
8706 Many changes in lib/silcske/silcske.[ch] and in
8707 lib/silcske/payload.[ch].
8709 * Added ^U functionality, clear input line. Patch from cras.
8711 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8713 * Mainly small bugfixes on core library. Fixed some debugging
8714 logging and buffer overflow in silclog.c.
8716 * Updated config.sub and config.guess on the distribution tree.
8718 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8720 * Added command lagging support in server. Client may execute
8721 commands now only once in two seconds.
8723 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8725 * Optimized packet reception. MAC computation and checking is now
8726 also more optimized. A lot previously duplicated code is now
8727 used as generic by both client and server.
8729 * Fixed key pair generation in clientutil.c
8731 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8733 * Added into lib/silccore/silcbufutil.[ch] new function;
8734 silc_buffer_realloc.
8736 * Moved generic packet sending/encryption functions to
8737 lib/silccore/silcpacket.[ch] from client and server. Some
8738 rewriting of the functions.
8740 * Moved all generic packet reception/decryption functions to
8741 lib/silccore/silcpacket.[ch] from client and server. The
8742 packet processing is now much cleaner in both client and server.
8743 These were major changes in both client and server.
8745 * Created many common functions in server to do packet sending.
8746 Previously code were duplicated a lot, this has been removed
8749 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8751 * Rewrote major parts of the ID cache system. Don't know
8752 whether it is better now or not but at least the API is more
8755 * Major rewrite on ID cache stuff on client because of the ID
8756 cache API changes. Added idlist.c to client.
8758 * Also major rewrite on ID cache stuff on server as well.
8759 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8760 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8761 in hand, instead they are all put into the ID cache system now.
8762 All server_idlist_* routines uses ID cache now instead of
8763 traversing its own lists (those lists does not exist anymore).
8764 SilcIDList though still exists. Also, SilcXXXEntry's are
8767 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8769 * Finally made the SKE implementation compliant to the protocol
8770 specification. All mp integers are now binary encoded as
8771 opposed being HEX encoded.
8773 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8776 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8777 functions: silc_[encode/decode]_pem. Also added function
8778 silc_encode_pem_file to PEM encode with newlines ('\n') for
8781 * SILC public keys are now encoded either PEM or binary. Same
8782 option is for private keys as well. By default private keys
8783 are binary encoded and public keys PEM encoded. Silly HEX
8784 encoding were removed.
8786 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8787 function to create fingerprints.
8789 * Fixed a bug in SHA1; does not change the original data anymore.
8791 * Partly implemented INFO command on client and server side.
8792 Fixed CLEAR command. Changes to SERVER command; show current
8793 server(s) when giving command without arguments. Added
8794 VERSION command to client.
8796 * Added check to server that unregistered connections cannot
8797 execute commands (unless it is specificly allowed).
8799 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * Fixed screen refresh.
8803 * Fixed channel joining bug from client. On some circumstances
8804 client tried to join to a channel it had already joined.
8806 * Added public key verification process into client's protocol.c.
8807 The client now verifies the public key from user and saves
8808 it into ~./silc/serverkeys/ directory.
8810 Added into: clientutil.[ch]: silc_client_verify_server_key.
8812 * Changed SKE protocol's silc_ske_initiator_finish function
8813 to accept callback function that verifies the received public
8814 key. Removed old silc_ske_verify_public_key function.
8816 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8818 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8819 silc_pkcs_private_key[_data]_set.
8821 * Made the password and public authentication more cleaner in
8822 server's protocol.c.
8824 * Removed historic and obsolete protocol `channel_auth' from
8825 both client and server.
8827 * Removed wrong way of sending command status messages from
8828 server to client in server's command.c. The old way violated
8829 protocol specification.
8831 Changes to silccore/silccommand.[ch]: removed
8832 silc_command_encode_status_payload -> not needed anymore,
8833 changed silc_command_encode_payload_va to accept extra
8834 argument on variable argument list. The argument type must
8835 now be provided to the function. Also, added new function:
8836 silc_command_encode_reply_payload_va which is same as
8837 normal command_encode_payload_va except command status type
8838 is provided as extra argument.
8840 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8842 * Added ~./silc directory handling. The directory includes the
8843 public and private keys for the client.
8845 Added silc_client_check_silc_dir, silc_client_create_identifier
8846 and silc_client_load_keys.
8848 * Implemented SILC protocol compliant public key. Added public
8849 and private key saving to and loading from files.
8851 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8852 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8853 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8854 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8855 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8857 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8858 silc_pkcs_load_[public/private]_key.
8860 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8862 * Added silc_server_get_route (route.[ch]) to get connection
8863 data for the fastest route for given ID.
8865 * Implemented INVITE command on client and server. The command
8866 were re-defined in the SILC Protocol Specification and the
8867 implementation now complies with the specification.
8869 * Implemented PING command on client and server.
8871 * Implemented NAMES command on client and server. The server side
8872 supports currently only normal server not router server yet.
8873 Some changes to NAMES definition in SILC protocol specification.
8875 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8877 * Implemented LEAVE command on client and server.
8879 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8880 again. This change was made to the protocol as well. Server
8881 should not violate the protocol specification anymore.
8883 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8885 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8886 was tested. SOCKS4 was not but should work anyway.
