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

143 Affected files configure.in.pre, lib/contrib/Makefile.am.
145 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
147 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
148 to the sender of the notify too, to avoid situation where two
149 notifys are in the network at the same time going to oppsite
150 directions. Affected file silcd/packet_receice.c.
152 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
154 * Delete the client from channel even if the cilent->id is
155 NULL. It was possible that client was deleted without
156 removing from channels (theoretically at least). Affected
157 file silcd/server.c and silcd/server_util.c.
159 * Free the client data too when resuming is not successful.
160 Affected file silcd/packet_receive.c.
162 * Merged some code from c0ffee's silc-plugin. Affected files
163 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
165 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
166 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
167 to the primary router connection, the other one returns
168 TRUE if packet must be broadcasted to network.
170 * All notifys that are destined to primary router (to network)
171 are now automatically sent to backup routers even if the
172 router is standalone (and has backup router). Affected files
175 * Added --without-irssi and --without-silcd configuration
176 options for disabling the compilation of these applications.
177 Affected file configure.in.pre and prepare.
179 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

182 UTF-8 encoding and decoding. Added also new encodings
183 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
185 Added also SILC_STRING_LANGUAGE which is language and charset
186 specific encoder and decoer for those platforms that support
187 iconv(). It can convert the UTF-8 to and from the locale
188 specific character set.
190 Affected file lib/silcutil/silcstrutil.[ch].
192 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
194 * Added function silc_get_command_name to the file
195 lib/silcutil/silcutil.[ch].

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

242 * When authenticating as founder during JOIN command, check
243 that the one authenticating becomes the only founder on the
244 channel. Affected file silcd/command.c.
246 * Better checking for founder mode setting when CUMODE_CHANGE
247 notify is received. Affected file silcd/packet_receive.c.
249 * Close all connections when shutting down the server by sending
250 DISCONNECT packet. Close all listeners too when shutting
251 down the server. Affected file silcd/server.c.

326 The one that authenticated will become founder and anyone
327 else is demoted. Affected file silcd/command.c.
329 * Added error printing of any error that has occurred during
330 any command in client library. Affected file is
331 irssi/src/silc/core/client_ops.c.

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

873 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
875 * Added STATS command to the protocol after all, to return
876 various statistical information about the network. It can
877 be used by clients to retrieve statistical information, and
878 servers may use it to to fetch cell and network wide
879 statistics from router. Updated the protocol specs and
880 implemented it to the server. Protocol TODO #16.
881 Affected files are lib/silccore/silccommand, silcd/command.[ch],
882 silcd/command_reply.[ch].
884 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
886 * The LIST command reply in client libary now adds new channel
887 entry if the returned channel doesn't exist yet in cache,
888 and returns the channel entry to the application in the
889 command_reply client operation. Affected file is
890 lib/silcclient/command_reply.c.
892 * Changed the channel message payload's MAC generation to
893 include the IV in the MAC as well. This way all relevant
894 parts of the channel message payload are authenticated also
895 with the channel message MAC (and not only by packet MAC).
896 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
897 Affected file is lib/silccore/silcchannel.c.
899 * Fixed the SKE to save the remote version, since the
900 silc_ske_parse_version mistakenly checked wrong version,
901 after it replaced the start payload. Affected files are
902 lib/silcske/silcske.[ch].
904 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

948 The killer's client entry is now returned to application in
949 the `notify' client operation.
951 * Fixed the Max Argument fields that had too large value set
952 in the protocol specs. Protocol TODO #14.
954 * Added the LEAVE command reply to return the ID of parted
955 channel. Updated protocol specs and implemented it to the
956 client and server. Protocol TODO #15. Affected files are

968 file is silcd/command.c.
970 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
971 generic reply to a generic request (REQUEST flag), and
972 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
973 way. A draft-riikonen-silc-flags-payloads-00.txt is written
974 to define the payload for DATA flag. Added the flags to
975 the implementation. Protocol TODO #9. Affected file is

983 and lib/silcclient/client_ops_example.c.
985 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
986 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
987 the channel. Updated protocol specs and impelemented this
988 to client and server. Protocol TODO #6. Affected files are
989 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

995 * Deprecated all administrative commands from SILC protocol
996 since they are highly implementation specific commands.
997 Updated protocol specs. Moved the old commands in
998 implementations to private range of command types. Affected
999 files are silcd/command.c, lib/silcclient/command.c and
1000 lib/silcclient/command_reply.c. Protocol TODO #8.

1018 Affected file silcd/protocol.c.
1020 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Some client implementations quit network by doing first LEAVE
1023 and then immediately SIGNOFF (like Bombyx). We now do check
1024 after a short time after LEAVE notify and check whether the
1025 client is still valid after LEAVE, and if not we remove it from
1026 cache. Affected file is lib/silcclient/client_notify.c.
1028 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1053 to const. Affected files are lib/silccrypt/silccipher.[ch],
1054 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1056 * Changed the silc_get_username and silc_get_real_name to
1057 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1059 * Fixed the Irssi SILC Client to use the silc_get_username and
1060 silc_get_real_name insted of glib routines since the glib
1061 routines only corrupt stack. Fixes the Irssi SILC to work in
1062 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1064 * Fixed the Irssi to not use g_get_home_dir since it crashes
1065 or returns garbage on cygwin and corrupts stack. Added function
1066 get_home_dir to Irssi routines. Affected files are
1067 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1069 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1071 * Made some structure optimizations. SFTP memory FS MemFSEntry
1072 entry structure. Optimized SilcTask structure. Optimized
1073 SilcPacketContext structure.
1075 Affected files lib/silcsftp/sftp_fs_memory.c,
1076 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1078 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1080 * And yet again reverted back the config thing since Johnny
1081 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1084 * Fixed memory leaks from config object. Affected files are
1085 silcd/serverconfig.[ch].
1087 * Added support for adding new connections to the server in rehash.
1088 After rehash they take effect.
1090 Added support for changing the maximum allowed connections in
1091 rehash. The number can grow but going smaller is not supported.
1093 Added function silc_server_num_sockets_by_remote to the
1094 silcd/server_util.[ch].
1096 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1098 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1100 * Added preliminary checking during config parsing for a valid
1101 public/private key and removed further checks in the code.
1102 Affected files are silcd/serverconfig.[ch], server.c.
1104 * Moved functions silc_server_drop() and silc_server_daemonise()
1105 from server.c to silcd.c since they are stricly related to
1106 the application activity.
1108 * Reverted a small part of the automatic ref/unref since
1109 it caused a double unref in some situations. Affected
1110 files are silcd/silcd.[ch], server.c, serverconfig.c.
1112 * Added some .cvsignore files in the lib directory.
1114 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Fixed silc_net_gethostbyaddr to correctly resolve by
1117 address. Affected file lib/silcutil/silcnet.c.
1119 * Fixed the notify relaying to client. The HMAC to be used
1120 with relayed packets ws wrong and caused decryption failure
1121 at the client end. Affected file is silcd/packet_receive.c.
1123 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1125 * Created new branch silc_protocol_1_0_branch.
1127 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1129 * Changed the silc_server_config_* routines to be SilcServer
1130 independent. They are now officially application specific code
1131 and not part of generic server implementation. Affected files
1132 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1134 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1136 * Added automatic referencing of config context in the
1137 silc_server_config_alloc, and automatic unreferencing in the
1138 silc_server_config_destroy. Affected files are
1139 silcd/serverconfig.[ch], silcd/silcd.c.
1141 * Fixed the silc_log_quick handling in the logging routines.
1142 It didn't log quickly when it was TRUE. Affected file is
1143 lib/silcutil/silclog.c. Also the flush delay was set even
1144 if it was 0 in config file. Affected file is
1145 silcd/serverconfig.c.
1147 * Added support for changing key pair of the server in rehash.
1148 Affected file silcd/server.c.
1150 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1153 too early, before getting the channel entry. Affected file
1154 is silcd/packet_receive.c.
1156 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1158 * Added functions silc_server_config_[ref/unref], these are used
1159 to prevent that the config object is destroyed.
1161 No longer directly affect global variables silc_log_quick and
1162 silc_log_delay, they are first cached inside the config object
1163 and then applied with silc_server_config_setlogfiles().
1165 silc_server_config_set_defaults() is now internal to
1166 serverconfig.c, there are no reasons to show this internal stuff
1169 Affected files are silcd/serverconfig.[ch].
1171 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1172 fprintf's to stderr, since some code may be executed again after
1173 the server went into the background. Affected files are
1176 * Added rehash support. Added function silc_server_rehash() that
1177 will perform all the basic tasks of the rehashing procedure.
1179 * Added command line option `-x, --hexdump'. This will enable the
1180 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1181 The option `--hexdump' implies `--debug'.
1183 * Fixed a bad bug in the logging APIs (silcutil library) where
1184 the application would crash after calling silc_log_reset_all().
1186 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1188 * Fixed the KICKED notify handling in client library to
1189 correctly remove the channel and all entries from the
1190 channel when I was kicked. This bug crashed the client.
1192 Fixed yet another but in KICKED notify handling to remove
1193 the kicked client correctly from the channel.
1195 Affected file is lib/silcclient/client_notify.c.
1197 * Fixed a minor bug in looking up correct client entry
1198 in KICKED notify in server. Affected file is
1199 silcd/packet_receive.c.
1201 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1202 sources correctly to distribution. Fixes --with-gmp option.
1204 * Removed the manual rehashing from ID Cache, and changed it
1205 to use the SILC Hash Table's auto rehash feature. Affected
1206 file is lib/silccore/silcidcache.c.
1208 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed a bug in the silc_client_nickname_format function that
1211 handles the multiple same nickname formatting. Two clients
1212 with same nickname caused problems after the first one left
1213 and rejoined. It didn't format the nickname correctly.
1214 Affected file is lib/silcclient/idlist.c.
1216 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1218 * Don't change the topic if olod topic is same as new one.
1219 Affected file is silcd/packet_receive.c.
1221 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1223 * Added cross-reference support to the SILC Documentation
1224 generator. All types across all HTML files are now cross-
1225 referenced. Affected files util/robodoc/generator.c and
1226 scripts/silcdoc/silcdoc.
1228 * Added file lib/silcutil/silctypes.h to include all the
1229 arithmetic type definitions and some macros. Removed
1230 includes/bitmove.h and moved macros to silctypes.h.
1232 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1234 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1236 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1238 * Added `type' argument to silc_id_payload_parse_id function which
1239 now returns the type of the ID to the sent pointer. Affected
1240 file is lib/silccore/silcid.[ch].
1242 * Added check for CMODE_CHANGE notify type that mode change is
1243 allowed by the sender. Affected file silcd/packet_receive.c.
1245 * Added check for CUMODE_CHANGE notify type that mode change is
1246 allowed by the sender. Affected file silcd/packet_receive.c.
1247 Added the ID type as CUMODE_CHANGE notify type as argument
1248 to the `notify' client operation. Affected files are
1249 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1251 * Added function silc_client_add_server to the client library.
1252 Added support for resolving also channel and server info when
1253 received unknown entity in notify packet. Affected files are
1254 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1256 * Added function silc_command_get_status to return the command
1257 status from the command reply's argument payload. Affected files
1258 are lib/silccore/silccommand.[ch].
1260 * Added check for KICKED notify type that the kicking is
1261 allowed by the client. Affected file silcd/packet_receive.c.
1263 * Created function silc_get_input which can be used to get input
1264 (echo on or off) from user on command line. Affected files are
1265 lib/silcutil/silcutil.[ch].
1267 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1269 * Optimized silc_server_packet_relay_to_channel function.
1270 Added new function silc_channel_message_payload_encrypt which
1271 can be called directly if channel message payload needs to
1272 be encrypted and is already encoded (no need to call _encode
1273 function). Packet relaying is now done by router without any
1274 extra memory allocations. Affected files are
1275 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1276 silcd/packet_send.c.
1278 * Fixed the INVITE notify handling. It took wrong arguments
1279 as invite list and invite delete. Affected file is
1280 silcd/packet_receive.c.
1282 * Added check for TOPIC_SET notify type that the topic change is
1283 allowed by the client. Affected file silcd/packet_receive.c.
1285 * Added check for INVITE notify type that inviting is allowed by
1286 the client. Affected file silcd/packet_receive.c.
1288 * Changed the silc_server_client_on_channel to return the
1289 SilcChannelClientEntry as well. Moved the function
1290 silc_server_check_cmode_rights to server_util.[ch].
1291 Affected files are silcd/server_util.[ch], silcd/command.c.
1293 * Added function silc_server_check_umode_rights to check whether
1294 changing client's user mode is allowed. Added check for
1295 UMODE_CHANGE notify type that the umode change is allowed
1296 by the client. Affected files are silcd/server_util.[ch],
1297 silcd/packet_receive.c and silcd/command.c.
1299 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1302 ID length. It ignored that ID can be IPv6 based as well.
1303 Affected file lib/silccore/silcpacket.h.
1305 * Fixed the silc_id_id2str and silc_id_str2id to take the
1306 IPv6 address offset's into consideration. Affecte file is
1307 lib/silccore/silcid.c.
1309 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed the internal Unix scheduler functions to check for
1312 NULL context they may receive. The affected file is
1313 lib/silcutil/unix/silcunixschedule.c.
1315 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1317 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1318 can specify different directory with --home command line
1319 parameter. Affected files irssi/src/silc/core/client_ops.c,
1322 * SILC-specific commands aren't now executed if the active server
1323 isn't of SILC-type, so there won't be problems with having
1324 IRC and SILC protocol support in same client. Affected files
1325 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1328 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1330 * Improved the signal support in SILC Schedule. Added new
1331 function silc_schedule_signal_call which is used by application
1332 to mark a signal to be called. It is now safe to perform
1333 any kind of tasks in signal callbacks since it is guaranteed
1334 that the application specified signal callback is called
1335 after the signal is over. Affected files are
1336 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1338 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Added `name' field to SilcChannelPrivateKey to represent
1341 application given name for the key. Moved also the context from
1342 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1343 Added the `name' argument also to the function
1344 silc_client_add_channel_private_key.
1346 Added function silc_client_current_channel_private_key to set the
1347 current channel private key in use.
1349 Added "change" command to KEY command which can be used to change
1350 the current channel private key. Bound the command also to
1351 alt+K (Alt+Shift+k).
1353 Also affected files lib/silcclient/client_channel.c,
1354 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1356 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Added silc_rng_get_byte_fast function in to the
1359 lib/silccrypt/silcrng.[ch].
1361 * Changed the interface of silc_packet_assemble and the
1362 silc_packet_send_prepare. If silc_packet_assmble is now
1363 called the application does not call silc_packet_send_prepare
1364 because the library will call it automatically. These
1365 interfaces now also return a reference to the outgoing buffer
1366 which includes the assembled packet, which the application can
1367 use to encrypt the packet.
1369 Affected files are lib/silccore/silcpacket.[ch],
1370 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1371 silcd/packet_send.c, server_backup.c and packet_receive.c.
1373 * Fixed a packet sending bug on very high load, where outgoing
1374 packet queue wasn't handled correctly and packets got corrupted.
1375 Affected files are lib/silcutil/*/silc*sockconn.c,
1376 lib/silcclient/client.c and silcd/server.c.
1378 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * Added macro SILC_PACKET_DATALEN which can be used during
1381 packet assembling to check whether the data to be added to
1382 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1383 len is truncated until it fits it.
1385 Added checks for maximum length of channel message payload and
1386 private message payload also.
1388 Added checks for maximum packet length in server and in
1391 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1392 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1393 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1394 lib/silcclient/client_prvmsg.c.
1396 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1398 * Added silc_server_packet_queue_purge call to the
1399 silc_server_disconnect_remote to assure that all data in the
1400 queue before disconnecting is sent to the network. Affected
1401 file silcd/server.c.
1403 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1405 * Added the deleting of server's own ID cache entry to the
1406 silc_server_free function. Free also everything else that
1407 has been allocated in silc_server_init. The affected file
1410 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1412 * Added functions silc_parse_version_string, silc_version_to_num,
1413 and silc_ske_parse_version to parse SILC protocol style version
1414 strings. Affected files lib/silcutil/silcutil.[ch] and
1415 lib/silcske/silcske.[ch].
1417 * Added new configuration params: version_protocol, version_software
1418 and version_software_vendor to specify what version the remote
1419 host must at least be to be able to connect to server. The vendor
1420 string can be regex matched too. Added new function
1421 silc_server_connection_allowed to check maximum number of allowed
1422 connections, and allowed versions for incoming connections.
1423 Affected files are silcd/server.c, server_util.[ch] and
1426 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Added preliminary support for signals in scheduler. The
1429 signals we care about are now blocked always when the scheduler
1430 is locked. This way we can synchronise the use of signal with
1431 scheduler. It is guaranteed that when signal occurs the scheduler
1432 is not locked, and thus new tasks can be safely added to the
1435 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1436 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1437 Added new platform specific routines
1438 silc_schedule_internal_signals_[un]block and
1439 silc_schedule_internal_signal_[un]register.
1441 Added new functions to SILC Schedule API:
1442 silc_schedule_signal_[un]register. Each signal that application
1443 is going to use should be registered to the scheduler.
1445 Affected files are lib/silcutil/silcschedule.[ch],
1446 lib/silcutil/*/silc*schedule.c.
1448 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1450 * Check for unauthenticated client and server in the
1451 silc_server_new_client and silc_server_new_server functions.
1452 Affected file silcd/packet_receive.c.
1454 * Added function silc_string_is_ascii to check whether given
1455 string is 7-bit ASCII string. Affected files are
1456 lib/silcutil/silcutil.[ch].
1458 * Added function silc_id_is_valid_server_id into the
1459 silcd/serverid.c and added checking for valid Server ID's in
1460 silc_server_new_server. The Server ID must always be based
1461 on the server's public IP address.
1463 * Added logging of DISCONNECT packet message in the server.
1464 Affected file silcd/server.c.
1466 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * Changed all library interfaces that use Global RNG to also
1469 accept SilcRng as argument. Affected files are
1470 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1471 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1472 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1473 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1474 lib/silccrypt/rsa.c.
1476 * Added function silc_pkcs_generate_key to the
1477 lib/silccrypt/silcpkcs.[ch] for applications so that they
1478 don't need to do pkcs->pkcs->init calls anymore.
1480 * Remove SilcSocketConnection from the SFTP API since it really
1481 wasn't needed there. The application has the information
1482 saved in its contexts anyway and the SFTP layer doesn't need
1483 know about it. Affected files lib/silcsft/silcsftp.h and
1484 lib/silcsftp/sftp_[server/client].c.
1486 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1487 The SilcSimContext is not SilcSim.
1489 * Fixed possible buffer overflows in silc_id_render in the
1490 lib/silcutil/silcutil.c.
1492 * On EPOC the global crypto module lists are not used at all
1493 in the crypto library. Added support for using the constant
1494 algorithm list on EPOC. Affected files are
1495 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1498 * Fixed the handling of third parameter of KICKED notify, since
1499 it was mistakenly updated to SILC Protocol 1.0 even though it
1500 is to be included in 1.1. Since it is not in 1.0 it is not
1501 mandatory, and this fix now handles it only if it is provided,
1502 and it is not error if it is not provided. Affected file
1503 lib/silcclient/client_notify.c.
1505 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1507 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1508 client. Affected file irssi/src/silc/core/client_ops.c.
1510 * Merged with Irssi 0.8.4 from irssi.org CVS.
1512 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1514 * Check for valid socket connection in client entries before
1515 sending any messages. Fixes a crash, but doesn't fix some
1516 other underlaying bug that is lurking there. Affected
1517 file silcd/packet_send.c.
1519 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1521 * $usermode, $cumode and $cumode_space expandos shouldn't do
1522 anything with non-SILC server records. Affected file
1523 irssi/src/silc/core/silc-expandos.c
1525 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1527 * Fixed the silc_net_check_[host/local]_by_sock to support
1528 IPv6 bound sockets as well. Now they can return IPv6 addresses
1529 as well. Affected file lib/silcutil/silcnet.c.
1531 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1532 Affected lib/silcutil/unix/silcunixnet.c.
1534 * Fixed ID rendering (at least on some platforms, not NetBSD)
1535 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1537 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1539 * Added silc_hash_public_key and silc_hash_public_key_compare
1540 functions to be used with SilcHashTable. They can be used to
1541 hash public keys and compare public keys in hash table. Affected
1542 file lib/silcutil/silcutil.[ch].
1544 * Added support for specifying multiple public keys for Client
1545 connection section in server configuration file. This makes it
1546 possible to accept multiple public keys from same host, or to
1547 make a section that accepts any incoming host, and have the
1548 accepted public keys listed in the section.
1550 Added functions silc_sever_[find/get]_public_key, added the
1551 support for this actually to all connection sections but only
1552 the Client section is currently allowed to specify multiple
1555 Affected files are silcd/server.c, server_internal.h,
1556 command.c, protocol.c, server_util.[ch], packet_receive.c.
1558 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1560 * Merged Irssi 0.8.2 from irssi.org CVS.

1727 the SKE interface a bit.
1729 * Fixed padding problem in PKCS#1. The padding was not actually
1730 random since the random number generator was used incorrectly.
1731 This security bug affects only when encrypting with PKCS#1, and
1732 it is not currently used at all in SILC. SILC only use signing
1733 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1818 the connection configuration object from the SilcServerConnection
1819 object instead of finding it during the connecting phase.
1820 Added the configuration object to SilcServerConnection struct.
1821 Affected files silcd/server_internal.h, server.c.
1823 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1825 * Add the client on channel after it was resolved at the
1826 channel message receiving, and it was not already on the
1827 channel. Affected file lib/silcclient/client_channel.c.

1849 public key is set. If not set, public key is preferred.
1850 This has effect only when being initiator (responder will try
1853 Added support for authentication with passphrase and public key
1854 at the same time. The passphrase is tried first always since
1855 it is faster to check.
1857 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1859 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1905 * Fixed the file transfer's key agreement payload to include
1906 zero port also if the hostname is NULL because it could not
1909 Call file transfer monitor callback now also if error occurs
1910 during key agreement protocol.
1912 Changed the silc_client_file_send interface to return the
1913 SilcClientFileError instead of session id. The session ID
1914 is returned into pointer provided as argument.

1955 the callback returned.
1957 Do not allow auto rehashing of hash table during the
1958 silc_hash_table_foreach operation, for same reasons as it is
1959 not allowed for SilcHashTableList. Affected files are
1960 lib/silcutil/silchashtable.[ch].

1986 * Fixed a bug in hash table tarversing. While the hash table
1987 is traversed with SilcHashTableList the table must not be
1988 rehashed. It is now guaranteed that auto rehashable tables
1989 are not rehashed while tarversing the list. Also defined that
1990 silc_hash_table_rehash must not be called while tarversing
1991 the table. Added function silc_hash_table_list_reset that must
1992 be called after the tarversing is over. The affected files are
1993 lib/silcutil/silchashtable.[ch].
1995 * Changed all hash table traversing to call the new
1996 silc_hash_table_list_reset in server and in client library.
1998 * Added function silc_client_on_channel to return the
1999 SilcChannelUser entry if the specified client entry is joined
2000 on the specified channel. This is exported to application as
2001 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2010 lists correctly. Affected file silcd/command.c.
2012 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2014 * When sending JOIN command to router for processing the
2015 sender's old command identifier was not saved back to the
2016 sender's command context, fixed now. The affected file is
2019 * Create the key in JOIN command of the router did not return
2020 the channel key, added check for this. Affected file is
2023 * Fixed a channel ID update bug in JOIN command reply. Do
2024 not directly upgrade the ID but call the function
2025 silc_idlist_replace_channel_id if the ID was changed.
2026 Affected file silcd/command_reply.c.
2028 * Fixed memory leaks from command calling if it would fail.
2029 Affected file silcd/command.c.

2060 user list for the channel again, and server won't be in
2061 desync in some rare circumstances. Affected file is
2062 silcd/packet_receive.c.
2064 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2090 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2092 * Added server & router operator statistics updating. Affected
2093 file silcd/packet_receive.c and silcd/command.c.
2095 * Fixed the SERVER_SIGNOFF notify handling on normal server
2096 not to save the history information for clients. Same was
2097 fixed earlier in remove_clients_by_server function, but not
2098 here. Affected file silcd/packet_receive.c.
2100 * Raised the default connection-retry count from 4 to 7 in
2101 server. Affected file silcd/server.h.
2103 * Cancel any possible reconnect timeouts when we start the
2104 key exchange. Affected file silcd/server.c.
2106 * Do not reconnect on connection failure when SCONNECT was
2107 given. Affected files silcd/server.[ch].
2109 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2111 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2113 * Fixed the NICK command to always give the unformatted
2114 nickname to the one giving the NICK command. If unformatted
2115 nickname is cached already it will be formatted and the
2116 local entry will always get the unformatted nickname.
2117 Affected file lib/silcclient/idlist.c.
2119 * Fixed some double frees from client library commands.
2120 Affected file is lib/silcclient/command.c.
2122 * Fixed CUMODE command in server to assure that no one can
2123 change founder's mode than the founder itself, there was a
2124 little bug. Affected file silcd/command.c.
2126 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2128 * Removed the SilcClientCommandDestructor from the client
2129 libary, it is not needed anymore. Affected files are
2130 lib/silcclient/silcapi.h, command[_reply].[ch],
2131 client_notify, idlist.c.
2133 * Fixed GETKEY command to first resolve client, and then
2134 resolve the server only if the client was not found, instead
2135 of resolving both at the same time. Affected file is
2136 lib/silcclient/command.c.
2138 * Added silc_client_start_key_exchange_cb and lookup the
2139 remote hostname and IP address before starting the key
2140 exchange with server. The affected file is
2141 lib/silcclient/client.c.
2143 * The server's public key is now saved using the IP address
2144 of the server and not the servername for the filename.
2145 The hostname public key filename is checked as an fall back
2146 method if the IP address based filename is not found.
2148 Fixed the GETKEY command to save the fetched server key
2149 in correct filename.
2151 Print the remote server's hostname now when new key is
2152 received during connection process. Affected file is
2153 irssi/src/silc/core/client_ops.c.
2155 * Return always our own public key to the client if it asks
2156 for it with GETKEY command. Affected file silcd/command.c.
2158 * Removed the use_auto_addr variable from default config
2159 file since it was in wrong section. Affected file is
2162 * Fixed TOPIC_CHANGE notification to not route it when it
2163 was sent using silc_server_send_notify_to_channel function.
2164 Affected file silcd/command.c.
2166 * Fixed silc_server_send_notify_kicked to send the kicker's
2167 Client ID also, it was missing. Affected files are
2168 silcd/command.c, silcd/packet_send.[ch].
2170 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2172 * Do not save client history information in SERVER_SIGNOFF.
2173 Fixes the bug in normal server that it does not detect
2174 the client becoming valid after the server becomes back
2175 online. Affected file silcd/server_util.c.
2177 * Added `sock_error' field into the SilcSocketConnection
2178 context. When error occurs during socket operation (read
2179 or write) the error is saved. Added also new function
2180 silc_socket_get_error to return human readable socket error
2181 message. Affected files are lib/silcutil/silcsockconn.[ch],
2182 lib/silcutil/unix/silcunixsockconn.c, and
2183 lib/silcutil/win32/silcwin32sockconn.c.
2185 * The server now prints the socket error message in the
2186 signoff for client. Affected file silcd/server.c.
2188 * Fixed the `created' channel information sending from router
2189 to server in JOIN command. Checks now whether the channel
2190 really was created or not and set it according that.
2192 Fixed the JOIN command to use the client entry's current
2193 ID during the joining procedure instead of the one it sent
2194 in the command (it is checked though), since it can change
2195 between the packet processing and command processing, and
2196 would just case unnecessary pain in the client end. Affected
2197 file silcd/command.c.
2199 * Fixed a channel key payload sending to use correct channel
2200 ID when the server was forced to change the channel's ID by
2201 router. Router sent the key payload with the old Channel ID.
2202 Affected file silcd/packet_receive.c.
2204 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2206 * Call silc_server_save_channel_key only if the key payload
2207 was provided in the JOIN command's command reply. Affected
2208 file silcd/command_reply.c.
2210 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2212 * Fixed silc_mp_sizeinbase to return the value correctly with
2213 MPI. Affected file lib/silcmath/mp_mpi.c.
2215 * Fixed the stop_server signal to correctly stop the scheduler
2216 and gracefully stop the server when SIGTERM or SIGINT signals
2217 are received. Affected file silcd/silcd.c.
2219 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2221 * Simple handling of TERM and HUP signals. Also added some log
2222 flushing call around. Affected file is
2225 * Fixed small bugs in silclog.c. Now buffering output will take
2226 effect after 10 seconds since startup: This will ensure that
2227 no important startup messages are lost. Also output redirection
2228 will preserve original format ([Date] [Type] message).
2229 Affected file is lib/silcutil/silclog.c.
2231 * Added two options to the config file, in the logging section:
2232 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2233 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2235 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Do not print the warning about log files not being initialized
2238 more than once to avoid excess logging. Affected file is
2239 lib/silcutil/silclog.c.
2241 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2242 the SIM copying in make install in Makefile.am.pre.
2244 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2246 * Rewritten silclog APIs. Globally interesting changes follows:
2247 silc_log_set_files() changed to silc_log_set_file().
2248 silc_log_set_callbacks() changed to silc_log_set_callback().
2249 ROBOdoc documented silclog header file.
2250 SilcLogCb now returns bool to wether inihibit the default
2251 handler or not (to keep the old behaviour return always TRUE).
2252 The new APIs should also fix the problem of the
2253 silcd_error.log file that was written in the current directory.
2256 Log files streams will remain opened after silc_log_set_file()
2257 call, means less CPU usage notably on high traffic servers.
2258 File streams are now full buffered, and flushed to the disk
2259 every 5 minutes, lesses HD activity and CPU usage.
2260 Messages can be redirected, allowing admins to configure
2261 one single logfile for all server messages.
2262 the silc_log_quick global variable to activate fast-logging.
2263 Affected files lib/silcutil/silclog.[ch]
2265 * Changed some code to conform new silclog APIs. Affected
2266 files are doc/example_silcd.conf.in, silcd/server.c
2267 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2270 * Fixed a memory leak that could occur in some situations.
2271 Affected file silcd/serverconfig.c.
2273 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2275 * Added the silc_client_del_client to remove the client from
2276 all channels as well. Affected file lib/silcclient/idlist.c.
2278 * Fixed the client library to correctly remove the client
2279 from all channels when the client entry is being destroyed.
2280 Affected file lib/silcclient/client_notify.c, command.c.
2282 * Added auto-nicking support to the client library. If the
2283 applicatio now sets client->nickname it will be sent to the
2284 server after connecting by the library. This way for example
2285 SILCNICK (or IRCNICK) environment variables will have effect
2286 and always change the nickname automatically to whatever
2287 it is wanted. Affected file lib/silcclient/client.[ch].
2289 * Renamed silc_server_command_bad_chars to the
2290 silc_server_name_bad_chars and moved it to the
2291 silcd/server_util.[ch]. Added also new function
2292 silc_server_name_modify_bad to return nickname that
2293 includes bad characters as new nickname without those
2294 bad characters. This check and modify is now used in
2295 silc_server_new_client when the username is initially set
2296 as nickname, so it must be checked to be valid nickname.
2297 Affected file silcd/packet_receive.c.
2299 * The nickname length is now taken from the packet for real
2300 and not trusted to strlen() since it clearly can return
2301 wrong length for nickname including bad characters. This
2302 also applies to channel names. Affected file silcd/command.c.
2304 * Removed the lib/silcsilm/modules directory. Modules are now
2305 compiled into the lib/silcsim. Fixed the copying of the
2306 modules to follow symbolic links in Makefile.am.pre.
2308 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2310 * Fixed silc_string_regexify list creation. Fixes bugs with
2311 BAN and INVITE commands in server. The affected file is
2312 lib/silcutil/unix/silcunixutil.c.
2314 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Removed the command destructor entirely from the server's
2317 command and command reply routines. It is not needed, and
2318 its usage was buggy and caused crashes. Affected files are
2319 silcd/command[_reply].[ch].
2321 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Cancel protocol and NULL sock->protocol if timeout
2324 occurred during protocol. Affected file silcd/server.c.
2326 * Cancel protocol timeouts always before calling the final
2327 callback, to assure that after final callback is called
2328 no other state will be called for the protocol anymore.
2329 Affected file silcd/protocol.c.
2331 * Print error log if incoming connection configuration could
2332 not be found. Affected file silcd/server.c.
2334 * Fixed JOIN command to correctly save the founder mode
2335 to the client on normal SILC server, when the channel
2336 was created by the router. Affected file silcd/command.c.
2338 * Fixed LIST command (hopefully) to send correct reply
2339 packets. Affected file silcd/command.c.
2341 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * The silc_packet_receive_process now returns FALSE if the
2344 read data was invalid packet, and TRUE if it was ok.
2346 The server now checks that if unauthenticated connection
2347 sends data and its processing fails the server will close
2348 the connection since it could be a malicious flooder.
2350 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2352 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Make sure the warning about error opening a log file is
2355 printed only once and not everytime it fails (produces
2356 too much useless log). Affected file lib/silcutil/silclog.c.
2358 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2360 * Made the silc_server_daemonise() function more readable.
2361 Affected file silcd/server.c.
2363 * Pid file is now optional, the user may comment it out from
2364 the config file. Removed define SILC_SERVER_PID_FILE, we
2365 don't need a default any longer. Affected file
2366 configure.in.pre, lib/Makefile.am.pre.
2368 * Make some use of the pid file. The server now dies at startup
2369 if it detects a valid pid file on his path. The server would
2370 die anyway in this circumstance, because of the bind() failure.
2371 Affected file silcd/silcd.c.
2373 * No longer compiling lib/dotconf.
2375 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Fixed JOIN command parsing not to crash. Affected file
2378 lib/silcclient/command.c.
2380 * Fied the NICK_CHANGE notify to add the new client entry
2381 even it is resolved. This removes an <[unknown]> nick
2382 thingy bug in the client. Affected file is
2383 lib/silcclient/client_notify.c.
2385 * Do not try to allocate 0 bytes (efence does not like it)
2386 in lib/silccore/silccomand.c when encoding payload.
2388 * Do not take IRCNICK as nickname in Irssi SILC client since
2389 it is not possible to set nickname before hand connecting
2390 the server (TODO has an entry about adding auto-nicking
2393 * Changed the silc_server_command_pending to check whether
2394 there already exists an pending entry with the specified
2395 command, command identifier and pending callback. This is
2396 to fix IDENTIFY and WHOIS related crashes that may register
2397 multiple pending commands with same identifier. Affected
2398 file silcd/command.c.
2400 * Fixed the server to reconnect to the router even if it
2401 was already reconnecting and EOF was received. This to
2402 fix a possibility that the server wouldn't ever try to
2403 auto-reconnect to the router. Affected file silcd/server.c.
2405 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Fixed the server's password authentication to use the
2408 length of the locally saved password, and not the one
2409 sent in the packet. Affected file silcd/protocol.c.
2411 * Fixed same password authentication problem in the
2412 Authentication Payload handling routines in
2413 lib/silccore/silcauth.c.
2415 * Yet another password authentication problem fixed with
2416 channel password handling in silcd/command.c.
2418 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * If first character of string in silc_parse_userfqdn is '@'
2421 then do not parse it. Affected file is
2422 lib/silcutil/silcutil.c.
2424 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Fixed minor bug in IDENTIFY command reply sending, which
2427 caused various weird problems during JOIN when it was
2428 resolving names for users. Affected file silcd/command.c.
2430 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Fixed the IDENTIFY command reply sending to chech better valid
2433 clients. It was possible to send incomplete list of replies.
2434 Affected file silcd/command.c.
2436 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Added silc_client_command[s]_[un]register functions now to
2439 dynamically register the commands in client library. Removed
2440 the static table of commands. This allows the client library
2441 to call commands without causing the application to know about
2442 what commands library has called.
2444 Removed the INFO command reply kludge to detect when the command
2445 was called by library. Now library use its own command reply
2446 function for INFO command.
2448 Added function silc_client_command_call to call a command.
2449 Application can use it to call command, not access the structure
2452 Now all commands that are sent by the client library (not
2453 explicitly sent by application) use own command reply functions.
2455 Affected files around lib/silcclient/ and in
2456 irssi/src/silc/core/.
2458 * Fixed the WHOIS command reply sending to chech better valid
2459 clients. It was possible to send incomplete list of replies.
2461 Fixed the WHOIS and IDENTIFY to send the request to router
2462 if normal server did not do it and did not find any results.
2464 Affected file silcd/command.c.
2466 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Moved the internal data from SilcClient context into its
2469 own file, not accesible to application. Affected files
2470 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2471 and other files in client library.
2473 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Added doc/examples installation target in Makefile.am.pre.
2478 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2481 commands the found client entry will be removed from the
2482 cache, after notifying application about the error. Affected
2483 file lib/silcclient/command_reply.c.
2485 * Changed the /MSG to check for exact nickname user gave, and
2486 not let `nick' match `nick@host' if it is only one found. Now,
2487 user must type the exact nickname (like nick@host2) even if
2488 there are no more than one same nicks found. This is to avoid
2489 a possibility of sending nickname to wrong nickname since
2490 `nick' could match `nick@host'. Affected file is
2491 irssi/src/core/silc-servers.c.
2493 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Do not print "you are now server operator" or similar when
2496 giving /away command. Affected files are
2497 irssi/src/silc/core/client_ops.c, silc-servers.h.
2499 * Made the silc_server_command_pending_error_check to send
2500 the same command reply payload it received back to the
2501 original sender of the command. This way all arguments
2502 that was received by the server will be received by the
2503 client too. Affected file silcd/command.c.
2505 * Added the silc_idcache_add to return the created cache entry
2506 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2508 * Add global clients to expire if they are not on any channel.
2509 This is because normal server will never know if they signoff
2510 if they are not on any channel. The cache expiry will take
2511 case of these entries. This is done by normal servers only.
2512 The affected files are silcd/command_reply.c,
2513 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2515 * If server receives invalid ID notification for WHOIS or
2516 IDENTIFY and the ID exists in the lists, it is removed.
2517 Affected file silcd/command_reply.c.
2519 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2520 in client then client entry that it matches is searched and
2521 the nickname is printed on the screen for user. Affected
2522 file irssi/src/silc/core/client_ops.c.
2524 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Use cache entry expire time in the LIST command reply to
2527 purge old entries from the cache after the LIST command
2528 reply has been received. This way we don't have non-existent
2529 entries in the cache for too long. Affected file is
2530 silcd/command_reply.c.
2532 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * If we are normal server, and we've not resolved client info
2535 in WHOIS or IDENTIFY from router, and it is global client,
2536 we'll check whether it is on some channel. If it is not
2537 then we cannot be sure about its validity and will resolve it
2538 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2539 file silcd/command.c.
2541 * Search channel by name (if possible) rather than by ID
2542 in IDENTIFY command's command reply. Affected file is
2543 silcd/command_reply.c.
2545 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2548 Updated specs and implemented it. Affected file silcd/command.c,
2549 silcd/packet_send.c and silcd/packet_receive.c.
2551 * Implemented the <founder auth> payload handling in the JOIN
2552 command. If provided all conditions for channel joining
2553 except requirement to provide correct passphrase can be
2554 overrided by the channel founder. Updated the protocol specs.
2555 Affected file silcd/command.c.
2557 Added support for founder auth in JOIN command in client
2558 library. Fixed the parsing of the JOIN command now to support
2559 all options as they should be. The affected file is
2560 lib/silcclient/command.c.
2562 * Optimized the WHOIS and IDENTIFY commands to send the request
2563 to router only if it includes nicknames or other names. If
2564 they include only IDs then check the local cache first before
2565 routing. Affected file is silcd/command.c.
2567 * Added channels topic announcements. Affected file is
2568 silcd/packet_receive.c and silcd/server.c.
2570 * Fixed the silc_server_send_notify_topic_set to really destine
2571 the packet to channel. Affected file silcd/packet_send.c.
2573 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2574 library. Affected file lib/silcclient/client_notify.c.
2576 * Added UMODE announcements. Affected file silcd/server.c.
2578 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Memory leak fixes in:
2582 lib/silcutil/silcsockconn.c
2583 lib/silcske/silcske.c
2584 lib/silcske/groups.c
2586 lib/silccrypt/silcpkcs.c
2587 lib/silccore/silccommand.c
2588 lib/silccore/silcidcache.c
2593 * ROBOdoc documented the lib/silcske/groups.h file and a
2594 bit changed the interface for better.
2596 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2598 * Update the client entry context in the ID cache after
2599 nick change. Affected file lib/silcclient/command.c.
2600 Fixes the CUMODE command when regaining founder privileges,
2601 and a little WHOIS problem.
2603 * Fixed silc_net_gethostbyname to correctly call the
2604 inet_ntop. Affected file lib/silcutil/silcnet.c.
2606 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2608 * Added IPv6 support checking to the configure.in.pre, added
2609 also --enable-ipv6 option to override the check. Affected
2610 file configure.in.pre.
2612 * The silc_thread_create now calls the start function
2613 directly if threads support is not compiled in. Removes
2614 ugly #ifdef's from generic code. Affected files are
2615 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.

2629 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2630 routines. Added silc_net_is_ip[4/6]. Affected file is
2631 lib/silcutil/unix/silcunixnet.c. All routines that take
2632 address as argument now supports both IPv4 and IPv6 addresses.
2634 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2636 * Fixed LIST command reply sending in server. Affected file
2639 * Server now sends the kicker's client ID in the KICK notify
2640 to the kicked client. Affected file silcd/command.c.
2642 * The client library now parses the kickers client ID and
2643 UI displays it. Affected files lib/silcclient/client_notify.c
2644 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2646 * Made all payload parsing function prototypes consistent.
2647 They all take now const unsigned char * and uint32 pair as
2648 the payload data instead of SilcBuffer. Changes all around
2649 the source tree. Other unsigned char* -> const unsigned char*
2650 changes around the tree as well.
2652 * Optimized SFTP client and server packet sending not to
2653 allocate new buffer for each packet but to recycle the
2654 first allocated buffer. Affected files are
2655 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2657 * Optimized the SFTP client to use SilcList instead of
2658 SilcDList for requests, because it is faster. Affected file
2659 is lib/silcsftp/sftp_client.c.
2661 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2662 into lib/silccore/silcid.[ch].
2664 Renamed silcpayload.[ch] into silcargument.[ch].
2666 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * If client entry is deleted with active key agreement
2669 session, abort the session.
2671 The silc_client_abort_key_agreement now calls the completion
2672 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2674 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2677 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Don't use __restrict in older GCC's. Affected file is
2680 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2682 * silc_net_localhost now attempts to reverse lookup the
2683 IP/hostname. Affected file lib/silcutil/silcnet.c.
2685 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2686 command. It can be used to gain founder privileges at
2687 the same time when joining the channel.
2689 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2690 kicker's client ID as well. Updated protocol specs.
2692 Defined that the server must send SILC_COMMAND_IDENTIFY
2693 command reply with error status to client who sent
2694 private message with invalid client ID.
2696 Updated the protocol specification.
2698 * Added silc_server_send_command_reply to send any
2699 command reply. Affected file silcd/packet_send.[ch].
2701 * Added silc_id_payload_encode_data to encode ID payload
2702 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2704 * The server now send IDENTIFY command reply with error
2705 status if client ID in private message is invalid. Affected
2706 file silcd/packet_receive.c.
2708 * Save the server key file with server's IP address in
2709 the filename instead of hostname. The affected file is
2710 irssi/src/silc/core/client_ops.c.
2712 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2717 * Added libtool support for compiling shared objects in
2718 lib/silcsim. Affected file configure.in.pre and
2719 lib/silcsim/Makefile.am. Original patch by cras.
2721 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Pid file configuration, and server's config file fixes
2724 patch by toma. Updated CREDITS file.
2726 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Fixed silc_client_channel_message to not try to decrypt
2729 the message twice if it resolved the destination client
2730 information. This could cause of dropping one channel
2731 message. Affected file lib/silcclient/client_channel.c.
2733 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2736 lib/silcclient/client.c. This function is used when the SILC
2737 Client is run under some other scheduler, or event loop or
2738 main loop. On GUI applications, for example this may be
2739 desired to used to run the client under the GUI application's
2740 main loop. Typically the GUI application would register an
2741 idle task that calls this function multiple times in a second
2742 to quickly process the SILC specific data.
2744 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2746 * Fixed silc_server_drop() for dropping the supplementary
2747 groups as well, this could cause a security hole on some
2750 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2755 * Write PID file after dropping privileges. Added -F option
2756 to run server on foreground. A patch by debolaz.
2757 Affected files silcd/server.c, silcd/silcd.c.
2759 * Fixed MOTD to return the MOTD file server name. Affected
2760 file silcd/command.c.
2762 * Added INFO command reply handling to the Irssi SILC Client.
2763 Affected file irssi/src/silc/core/client_ops.c.
2765 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Fixed the silc_idcache_list_* routines to really support
2768 the dynamic list. Fixes a crash. Affected file is
2769 lib/silccore/silcidcache.c.
2771 * Fixed the LIST command reply to really call LIST command's
2772 pending callbacks. Affected file silcd/command_reply.c.
2774 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2776 * Update conn->local_entry->nickname after giving NICK
2777 command. Affected file lib/silcclient/command.c.
2779 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2781 * Added the [pid] option to the silcd configuration file
2783 Affected files: serverconfig.[ch] and silcd.c
2785 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Save fingerprint in WHOIS command reply in server.
2788 Affected file silcd/command_reply.c.
2790 * Fixed NICK commands pending callback registration.
2791 Affected file lib/silcclient/command.c.
2793 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Use ++server->cmd_ident when sending commands in server,
2796 instead of random number. Affected file silcd/command.c.
2798 * Fixed GETKEY command reply to call actually GETKEY pending
2799 command callbacks. Affected file silcd/command_reply.c.
2801 * A bit stricter check for nicknames. Check for same nickname
2802 in NICK command also. Affected file silcd/command.c.
2804 * Do not call INFO command everytime client ID changes, only
2805 during first connecting. Affected file lib/silcclient/client.c.
2807 * Set the new nickname only after successful command reply for
2808 NICK command is returned by server. Affected file
2809 lib/silcclient/command.c.
2811 * Remove nicknames from nicklist during server_signoff notify.
2812 Should fix /NAMES bit more. The affected file is
2813 irssi/src/silc/core/silc-channels.c.
2815 * Added `fingerprint' field to the SilcIDListData in the
2816 silcd/idlist.h to hold the fingerprint of the client's
2819 Send the fingerprint of the client's public key in WHOIS
2822 Affected files silcd/command.c, and silcd/idlist.[ch].
2824 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2825 create fingerprint from given data.
2827 * Show the fingerprint of the client's public key in WHOIS.
2828 Affected files irssi/src/module-formats.[ch] and
2829 irssi/src/silc/core/client_ops.c.
2831 * Format the multiple same nicknames also during JOIN and
2832 NICK_CHANGE notifys. Affected file is
2833 lib/silcclient/client_notify.c.
2835 * Do not print error on screen for invalid private message
2836 payload since it can come if someone is sending private
2837 messages with wrong key. Affected file
2838 lib/silccore/silcprivate.c.
2840 * Fixed multiple concurrent /PING crash. Affected file
2841 lib/silcclient/command.c.
2843 * Changed the wrong ID encoding. All IP addresses must be
2844 in MSB first order in encoded format. They were encoded
2845 wrong and was in LSB format. Affected files are
2846 silcd/serverid.c, lib/silcutil/silcutil.c.
2848 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2850 * Call the `connect' client operation through the scheduler
2851 in case of error. Affected file lib/silcclient/client.c.
2853 * Call the `failure' client operation even if the error
2854 occurred locally during a protocol. Affected file is
2855 lib/silcclient/protocol.c.
2857 * Added support of sending LIST command to router from normal
2858 server. This way normal server can get list of all channels
2859 in the network too. Fixed the channel list sending in the
2860 server too. Affected files are silcd/command.c, and
2861 silcd/command_reply.[ch].
2863 * Added silc_server_update_channels_by_server and
2864 silc_server_remove_channels_by_server. They are used during
2865 disconnection of primary router and in backup router protocol.
2866 Affected file silcd/server_util.[ch], silcd/server.c and
2867 silcd/server_backup.c.
2869 * Fixed channel adding to global list in IDENTIFY command
2870 reply in server. Affected file silcd/command_reply.c.
2872 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * If the incoming packet type is REKEY or REKEY_DONE process
2875 that packet always synchronously. Fixes yet another MAC
2876 failed error on slow (dialup) connections. Affected file
2877 lib/silcclient/client.c and silcd/server.c.
2879 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Call check_version SKE callback for initiator too. Affected
2882 file lib/silcske/silcske.c.
2884 * Implemented fix for security hole found in the SKE that was
2885 fixed in the specification few days back; the initiator's
2886 public key is now added to the HASH value computation.
2887 Added backwards support for the old way of doing it too, for
2888 old clients and old servers. Affected file is
2889 lib/silcske/silcske.c.
2891 * Enabled mutual authentication by default in SKE. If initiator
2892 is not providing mutual authentication the responder will
2893 force it. This will provide the proof of posession of the
2894 private key for responder. The affected files are
2895 lib/silcclient/protocol.c and silcd/protocol.c.
2897 * Do not cache anymore the server's public key during SKE.
2898 We do mutual authentication so the proof of posession of
2899 private key is done, and if the server is authenticated in
2900 conn auth protocol with public key we must have the public
2901 key already. Affected file silcd/protocol.c.
2903 * Added new global debug variable: silc_debug_hexdump. If
2904 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2905 file lib/silcutil/silclog.[ch].
2907 * Fixed compilation warning due to char * -> const char *.
2908 Affected files lib/silcutil/silcnet.h, and
2909 lib/silccore/silcauth.[ch].
2911 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Fixed CMODE command when new channel key was created. If
2914 the creation failed the old key was removed. Next time giving
2915 same command would crash the server since the old key was
2916 freed already. Affected file silcd/command.c.
2918 * Fixed the silc_server_announce_get_channels to not crash
2919 on reconnect. Affected file silcd/server.c.
2921 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Added silc_log_set_debug_string function to set a regex
2924 string to match for debug output. Only the function names,
2925 or filenames matching the given debug string is actually
2926 printed. This way it is possible to filter out those debug
2927 strings that user is not interested in.
2929 Fixed a bug in silc_string_regexify.
2931 Affected files lib/silcutil/silclog.[ch], and
2932 lib/silcutil/unix/silcunixutil.c.
2934 * Changed the -d options in both server and Irssi SILC client
2935 to take the debug string as argument. Affected files
2936 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2938 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Added silc_hash_babbleprint to create a Bubble Babble
2941 Encoded fingerprint. The encoding is developed by Antti
2942 Huima (draft-huima-babble-01.txt), and it creates human
2943 readable strings out of binary data. Affected file
2944 lib/silccrypt/silchash.[ch].
2946 * Print the babble print now in addition of fingerprint as well
2947 in Irssi SILC client. Affected files are
2948 irssi/src/fe-common/silc/module-formats.[ch],
2949 irssi/src/fe-common/silc/core/client_ops.c.
2951 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Fixed a security problem found in SKE. The initiator's
2954 public key too is now added to the HASH hash value creation
2955 which is signed by the responder to create the SIGN value.
2956 This will prevent anyone in the middle to lie to the responder
2957 about the initiator's public key. If this is done now, the
2958 man in the middle will get caught. Updated the protocol
2961 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Better installation directory handling. Configure module
2964 paths and other paths automatically to example_silc* files
2965 in doc/. A patch by toma.
2967 * Fixed compiler warning from MPI library, and from SILC RNG.
2970 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2971 It can be configured with ./configure. A patch by toma.
2973 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Find correct make to use in prepare-clean. A patch by
2976 toma. Affected file prepare-clean.
2978 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2980 * Added irssi variables use_auto_addr, auto_bind_ip,
2981 auto_bind_port and auto_public_ip.
2983 * Changed the interface for silc_client_send_key_agreement
2984 in lib/silcclient/silcapi.h
2988 irssi/src/silc/core/silc-core.c
2990 lib/silcclient/silcapi.h
2991 irssi/src/silc/core/silc-channels.c
2992 lib/silcclient/client_keyagr.c
2995 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Added silc_pkcs_public_key_compare to compare two
2998 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3000 * Check that the client who set the founder mode on the
3001 channel is the same client that is giving the founder
3002 mode to itself. It is done by comparing the saved public
3003 key (it is saved even in the authentication is passphrase).
3004 Affected file silcd/command.c.
3006 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Do not process packet for disconnected socket connection.
3009 Affected file lib/silccore/silcpacket.c.
3011 * Process the DISCONNECT packet through scheduler in the
3012 client library. Affected file lib/silcclient/client.c.
3014 * Fixed the silc_client_packet_parse to not to increase
3015 the packet sequence number if the conn->sock and the
3016 current socket connection is not same. This can happen
3017 for example during key agreement when the conn includes
3018 multiple socket connections (listeners). Affected file
3019 lib/silcclient/client.c.
3021 * The sender of the file transfer request now provides also
3022 the pointer (listener) for the key exchange protocol. If
3023 the listener cannot be created then it sends empty key
3024 agreement and lets the receiver provide the listener.
3026 Added `local_ip' and `local_port' arguments to the
3027 silc_client_file_send. If they are provided they are used,
3028 if not then it will attempt to find local IP address, if
3029 not found or bind fails then the remote client will provide
3032 Affected files are lib/silcclient/client_ftp.c and
3033 lib/silcclient/silcapi.h.
3035 * Extended the FILE SEND command to support defining the
3036 local IP and port for key exchange listener. They are
3037 optional. Affected file irssi/src/silc/core/silc-servers.c.
3039 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Defined to WHOIS command reply the sending of fingerprint
3042 of the client's public key (if the proof of posession of the
3043 corresponding private key is verified by the server).
3044 Updated to the protocol specification.
3046 * Added support of receiving the client's public key's
3047 fingerprint in command reply in client library. Affected
3048 file is lib/silcclient/command_reply.c, and
3049 lib/silcclient/idlist.[ch].
3051 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Do not send over 128 chars long nickname to the server
3054 in NICK command. Affected file lib/silcclient/command.c.
3056 * Do not send over 256 chars long channel names to the server
3057 in JOIN command. Affected file lib/silcclient/command.c.
3059 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Assure that silc_server_close_connection cannot be called
3062 twice for same socket context. Affected file is
3065 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Send error message to application if opening file for
3068 writing during file transfer fails. Affected file is
3069 lib/silcclient/client_ftp.c.
3071 Remove all file transfer sessions for a client that we're
3072 removing from ID cache.
3074 Affected file is lib/silcclient/client_ftp.c.
3076 * Fixed silc_net_addr2bin to return correct address. Affected
3077 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3079 * Fixed file transfer session removing on signoff notify.
3080 Affected file irssi/src/silc/core/silc-servers.c.
3082 * Added the SilcClientFileError to be returned in the monitor
3083 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3084 Affected file lib/silcclient/silcapi.h.
3086 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Fixed a crash in silc_client_ftp_free_sessions and
3089 silc_client_ftp_session_free_client. Affected file
3090 lib/silcclient/client_ftp.c.
3092 * Added `disabled' field in the SilcChannelEntry in the server
3093 to indicate if the server entry is disabled. Affected file
3094 silcd/idlist.h, silcd/command[_reply].c.
3096 * SILC server adds now /var/run/silcd.pid everytime it is
3097 started. Affected file silcd/silcd.c.
3099 * Added silc_server_packet_send_clients to send a packet to
3100 the provided table of client entries. Affected file
3101 silcd/packet_send.[ch].
3103 * Fixed a crash in client resolving in client_prvmsg.c in
3104 client library. Affected file lib/silcclient/client_prvmsg.c.
3106 * Do not actually remove the client directly from ID cache
3107 during SERVER_SIGNOFF, but invalidate it. This way we
3108 preserve the WHOWAS info for the client. Affected file
3109 silcd/server_util.c.
3111 * Fixed SERVER_SIGNOFF notify handling in the server. The
3112 server is now able to process incoming SERVER_SIGNOFF notify
3113 for a server that it doesn't even know about. It will remove
3114 the clients provided in the notify. Affected file
3115 silcd/packet_receive.c.
3117 * Check for partial packet in data queue after every packet that
3118 was found from the queue. Return and wait for more data if
3119 there is partial data in queue. Affected file is
3120 lib/silccore/silcpacket.c.
3122 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Added SilcClietFileError enum to indicate error in
3125 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3126 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3127 Affected files lib/silcclient/silcapi.h and
3128 lib/silcclient/client_ftp.c.
3130 * Check that newsize in silc_buffer_realloc is larger than
3131 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3133 * Added better monitor of file transfers. It now monitors
3134 key agreement protocol during the file transfer too. Added
3135 error reporting too. Affected files
3136 irssi/src/silc/core/silc-servers.c,
3137 irssi/src/fe-common/silc/module-formats.[ch].
3139 * Wrote a help file for FILE command.
3141 * Added silc_rng_global_get_byte_fast to get not-so-secure
3142 random data as fast as possible. Random data is read from
3143 /dev/urandom if available and from the SILC RNG if not
3144 available. It is used in padding generation. Affected file
3145 lib/silccrypt/silcrng.[ch].
3147 * All packets in client library are now processed synchronously.
3148 Optimized packet processing a lot. Affected file
3149 lib/silcclient/client.c.
3151 * All server connection packets are processing synchronously
3152 now in server, to optimize packet processing. Affected file

3156 if make install is given. Affected files: all Makefile.am's.
3158 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Assure that silc_client_notify_by_server_resolve does not
3161 resolve the client information multiple times. If it cannot
3162 be found by the first it cannot be found at all. Affected
3163 file lib/silcclient/client_notify.c.
3165 * Fixed WHOWAS command reply calling. Affected file
3166 lib/silcclient/command_reply.c.
3168 * Removed all references to silc_idlist_get_client from the
3169 Irssi SILC client since that call is internal call used by
3170 the library. The Irssi SILC client will use now client
3171 retrieval functions found in silcapi.h.
3173 * Fixed a bug in resolving nickname info before sending
3174 private message. It used freed memory. Affected file
3175 irssi/src/silc/core/silc-servers.c.

3196 * Added silc_net_localip to return local host's IP address.
3197 Affected file lib/silcutil/silcnet.[ch].
3199 * If key exchange or rekey protocol is active for a connection
3200 parse all packets syncronously since there might be packets
3201 in packet queue that we are not able to process without first
3202 processing packets before them. Affected file silcd/server,
3203 lib/silcclient/client.c.
3205 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3206 whether library should continue processing the packet.
3207 Affected file lib/silccore/silcpacket.h.
3209 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3242 * Resolve the client info when received private message or
3243 channel message for a client which nickname we don't know.
3244 Affected files lib/silcclient/client_prvmsg.c and
3245 lib/silcclient/client_channel.c.
3247 * Do not crash in /KEY if client is not connected. Affected
3248 file irssi/src/silc/core/silc-channels.c.
3250 * Added SilcClientStatus field to the SilcClientEntry in the

3253 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3254 is incomplete and is being resolved, it won't be resolved
3257 Make sure also that USERS command reply does not resolve
3258 twice information. Affected file is
3259 lib/silcclient/command_reply.c.
3261 Make sure that silc_client_get_clients_by_list does not
3262 resolve twice same information.
3264 * Check for valid client->id in the silc_server_free_client_data.
3265 Affected file silcd/server.c.
3267 * Fixed /GETKEY nick@server not to crash if the server entry
3268 is not found. Affected file lib/silcclient/command.c.
3270 * Fixed the silc_server_check_cmode_rights to check the
3271 requested modes correctly. Affected file silcd/command.c.

3275 * Better checks for non-printable chars in nick added.
3276 Affected file silcd/command.c.
3278 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Call the silc_server_udpate_servers_by_server in the
3281 primary router that comes back online in the backup resuming
3282 protocol. Otherwise it routes packets wrong. Affected file
3283 silcd/server_util.[ch], silcd/server_backup.c.
3285 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3288 lib/silcutil/silcbuffmt.[ch].
3290 * Redefined the SILC packet header to include the padding
3291 length. Affected file lib/silccore/silcpacket.[ch].
3293 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3294 length for maximum padding up to 128 bytes). Affected
3295 file lib/silccore/silcpacket.h.
3297 * Removed all backwards support for old 0.5.x MAC thingies.
3298 The SILC packet header change makes it impossible to be
3299 backwards compatible.
3301 * Send the ENDING packet with timeout in the backup resuming
3302 protocol. This is to assure that all routers has connected
3303 to the primary router. Affected file silcd/server_backup.c.
3305 * Changed the RNG to take the first IV from random data. It
3306 used to take it from zero actually. Changed the RNG also
3307 to use /dev/urandom during session. /dev/random is used
3308 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3310 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Changed the SILC packet header to have the first two bytes
3313 (the packet length) encrypted. Affected files aroung the
3314 code tree, lib/silccore/silcpacket.[ch]. Removed the
3315 SilcPacketCheckDecrypt callback. It is not needed anymore
3316 since the silc_packet_receive_process will determine now
3317 whether the packet is normal or special.
3319 * Implemented the unidirectional MAC keys. Affected files
3320 lib/silcske/silcske.c, silcd/protocol.c and
3321 lib/silcclient/protocol.c.
3323 * Implemented the packet sequence number to the MAC computation.
3324 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3325 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3326 lib/silcclient/protocol.c.
3328 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Allow backup router to announce servers. All servers
3331 announced by backup router are added to the global list
3332 automatically. Update hte server's socket to our primary
3333 router also when backup router announces a server.
3334 Affected file silcd/packet_receive.c.
3336 * Do not update the client->router in the function
3337 silc_server_udpate_clients_by_server if the client is on
3338 global list. We might fail to find any specific server
3339 for locally connected clients and local cell clients. They
3340 should still use the `from' and not `to' as client->router.
3341 This fixes backup router resuming protocol. Affected file
3342 silcd/server_util.c.
3344 * Decrease channel statistics count only if the channel
3345 deletion worked. Affected files are silcd/server.c and
3346 silcd/server_util.c.
3348 * Added silc_server_update_servers_by_server to update origin
3349 of all server entries. Used during backup router protocol.
3350 Affected files silcd/server_util.[ch], silcd/server.c. and
3351 silcd/backup_router.c.
3353 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3354 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3355 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3356 lib/silccrypt/silchmac.c.
3358 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Assure that router cannot reroute the same channel message
3361 to the sender. Affected file silcd/packet_receive.c.
3363 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * Made better checks that the channel message is not sent
3366 to the router it came from. Affected file is
3367 silcd/packet_send.c. Fixed memory leak too.
3369 * Announce informations for incoming router connection, but
3370 only after checking if it is replaced by backup router.
3371 Affected file silcd/packet_receive.c.
3373 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Fixed the backup resuming protocol to work in multiple
3376 router environment. Affected file silcd/server_backup.c.
3378 * Route packet only to one router in the function
3379 silc_server_packet_send_to_channel. Affected file is
3380 silcd/packet_send.c.
3382 * Fixed silc_server_send_notify_dest to set the broadcast
3383 flag. Fixed the silc_server_send_notify_topic to actually
3384 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3385 Affected file silcd/packet_send.c.
3387 * Changed the SFTP Filesystem interface. Changed the
3388 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3389 the filesystem operation function. The SilcSFTPFilesystem
3390 is now a context that is allocated by all filesystem allocation
3391 functions and it already includes the operations structure
3392 and filesystem specific context. It is given as argument
3393 now to the silc_sftp_server_start. This made the interface
3394 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3395 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3397 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * Changed the backup router adding and getting interfaces
3400 in the server. The router that will be replaced by the
3401 specified backup router is now sent as argument. Affected
3402 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3405 * Added silc_net_addr2bin_ne to return the binary form of
3406 the IP address in network byte order. Affected files
3407 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3409 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Check for existing server ID in silc_server_new_server
3412 and in silc_server_connect_to_router_final and remove the
3413 old entry if it exists. Affected file silcd/packet_receive.c,
3416 * Send the channel message always to only one router, either
3417 in upstream or downstream. Affected file is
3418 silcd/packet_send.c.
3420 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Wrote the definition of the backup resuming protocol to the
3423 protocol specification.
3425 * Removed one redundant channel key generation from normal
3426 server during joining procedure. Removed one redundant
3427 channel key sending from server to router during joining
3428 procedure. Affected file silcd/command.c.
3430 * Made minor bugfixes to the backup router resuming protocol.
3431 Affected file silcd/server_backup.c, server.c.

3436 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3439 * Implemented the backup resuming protocol that is used to
3440 resume the primary router position in the cell after the
3441 primary router comes back online. Affected files
3442 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3443 and silcd/server_util.[ch].
3445 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Sleep two (2) seconds after sending QUIT command to server.
3448 Affected file lib/silcclient/command.c.
3450 * Assure that if outgoing data buffer is pending do not force
3451 send any data. Affected file silcd/packet_send.c.
3453 * Assure that if outgoing data buffer is pending do not force
3454 send any data. Affected file lib/silcclient/client.c.
3456 * Implemented the backup router support when the primary router
3457 goes down. The servers and routers can now use the backup
3458 router as new primary router without loosing connectivity.
3460 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3463 in the server to indicate disabled entry. All data read
3464 from the connection will be ignored and no data is sent
3465 for entry that is disabled. Affected files are
3466 silcd/idlist.h, silcd/server.c.
3468 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3470 * Created SFTP client and server test programs in the
3471 lib/silcsftp/tests directory.
3473 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Implemented memory filesystem (virtual filesystem) for
3476 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3479 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Implemented the SFTP (SSH File Transfer Protocol) to the
3482 lib/silcsftp. It includes SFTP client and SFTP server
3485 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Moved lib/silccore/silcprotocol.[ch] to the
3488 lib/silcutil library.
3490 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3491 take variable argument list pointer as argument. Affected
3492 file lib/silcutil/silcbuffmt.[ch].
3494 * Added silc_buffer_set function that is used to set data
3495 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3496 Affected file lib/silcutil/silcbuffer.h.
3498 * Changed various routines in the core library to use the new
3499 silc_buffer_set instead of allocating new buffer only for
3502 * Added 64-bit value formatting and unformatting support to the
3503 silc_buffer_[un]format routines. Affected file is
3504 lib/silcutil/silcbuffmt.[ch].
3506 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3507 to includes/bitmove.h.
3509 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * Fixed channel user mode saving in client library. Affected
3512 file lib/silcclient/command[_reply].c.
3514 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Defined the file transfer to the SILC Protocol. Added
3517 new packet type SILC_PACKET_FTP and defined File Transfer
3518 Payload. The mandatory file transfer protocol is SFTP
3519 (SSH File Transfer Protocol). Affected file in addition
3520 of the internet draft is lib/silccore/silcpacket.h.
3522 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3523 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3524 is used as part of backup router protocol when the primary
3525 router of the cell is back online and wishes to resume
3526 the position as primary router.
3528 * Redefined the MAC generation keys in the protocol. The
3529 same key is not used anymore in both direction. Both
3530 direction will now use different keys for sending and
3531 receiving. This fixes a potential security flaw. This
3532 change causes incompatibilities in the protocol.
3534 * Redefined also the MAC computation from the packet.
3535 An packet sequence number is now added to the MAC
3536 computation. This prevents possible replay attacks against
3537 the protocol. This change too causes incompatibilities
3540 Added `sequence' field to the SilcPacketContext to hold
3541 the current sequence number for the packet.
3543 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Added `created' field to the SilcIDListData in the file
3546 silcd/idlist.h to indicate the time when the entry was
3549 * Added `created' field to the SilcChannelEntry too. Affected
3550 file silcd/idlist.h.
3552 * Added `creation_time' aguments to all the announcement functions
3553 in the server. If it is provided then only the entries that
3554 was created after the provided time frame are actually
3555 announced. Affected file silcd/server.[ch].
3557 * The protocol says that the Channel ID's IP address must be
3558 based on the router's IP address. Added check for this in
3559 the silc_server_new_channel when processing incoming New Channel
3560 Payload. Affected file silcd/packet_receive.c.
3562 * Print out the correct version with --version in SILC client.
3563 Affected file irssi/src/silc/core/silc-core.c.
3565 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Fixed WHOWAS command to check for completnes of the client
3568 entry always, not just when the command is coming from client.
3569 Affected file silcd/command.c.
3571 * Added new function silc_server_packet_queue_purge to purge the
3572 outgoing data queue to the network. After the function returns
3573 it is guaranteed that the outgoing packet queue is empty.
3574 Affected file silcd/packet_send.[ch].
3576 * Purge the outgoing packet queue in the rekey protocol's final
3577 callback to assure that all rekey packets go to the network
3578 before quitting the protocol. Affected file silcd/server.c.
3580 * Added silc_client_packet_queue_parse as similar function as
3581 in server to the client library. The affected file is
3582 lib/silcclient/client.c.
3584 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Splitted silcd/server.c and created silcd/server_util.[ch]
3587 for utility functions.
3589 * Added new socket flag SILC_SF_DISABLED to indicate that the
3590 connection is open but nothing can be sent to or received from
3591 the connection. Affected file lib/silcutil/silsockconn.[ch].
3592 The checking for disabled socket is checked in the low level
3593 silc_socket_write and silc_socket_read functions.
3595 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Allow only nicknames and channel names that fits into the
3598 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3600 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * When processing JOIN command reply in server check that if
3603 the channel exists in our global list we'll move it the local
3604 list. Affected file silcd/command_reply.c.
3606 * Fixed the check whether client is joined on the channel already
3607 in JOIN command. Affected file lib/silcclient/command.c.
3609 * Fixed the JOIN command reply to check whether the channel
3610 already exists. Affected file lib/silcclient/command_reply.c.
3612 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3614 * Added silc_ske_status_string to map the SKE error numbers
3615 to readable strings. The affected files are
3616 lib/silcske/silcske[_status].[ch].
3618 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Do not show the private channels on the WHOIS channel list
3621 as it is not allowed by the protocol. The affected file is
3624 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Assure that the packet length digged from the actual packet
3627 is something sensible in the silc_packet_decrypt_rest_special
3628 in lib/silccrypt/silcpacket.c.
3630 * Free and NULL the allocated pointer in silc_hmac_alloc if
3631 the HMAC allocation fails. The affected file is
3632 lib/silccrypt/silchmac.c.
3634 * Print the selected security properties to the log files in
3635 the server. Affected file silcd/protocol.c.
3637 * Add SKE's reference counter even if calling the completion
3638 callback manually. Otherwise it goes negative, although it
3639 does not cause any problems. The affected file is
3640 lib/silcske/silcske.c.
3642 * Remove the client entry with short timeout after giving the
3643 KILL command. Affected file lib/silcclient/command.c.
3645 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3646 case all found clients are already disconnected (WHOWAS would
3647 found them) in the server. Affected file silcd/command.c.
3649 * Update the last_receive (time of last data received) to be
3650 updated only when received private or channel message so that
3651 the idle time showed in WHOIS makes more sense.
3653 * Added boolean field `valid' in to the SilcClientEntry in the
3654 client library to indicate whether the entry is valid or not.
3655 This fixes the nickname change bug on channel when changing
3656 the nickname to be same than the old (like nick to Nick) the
3657 nickname formatter doesn't set the new nick anymore to Nick@host.
3658 Affected file lib/silcclient/idlist.[ch].
3660 * Now actually fixed the nickname changing on disconnection.
3661 Added new function silc_change_nick to the Irssi SILC Client.
3662 Affected file irssi/src/silc/core/client_ops.c,
3663 irssi/src/silc/core/silc-nicklist.[ch].
3665 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Check that the public key exists in the GETKEY command before
3668 trying to encode it. Affected file silcd/command.c.
3670 * Print some notifications on received public keys with GETKEY
3671 command in the Irssi SILC Client. Affected files are
3672 irssi/src/fe-common/silc/module-formats.[ch],
3673 irssi/src/silc/core/client_ops.c.
3675 * Use IDENTIFY command to resolve the server information in the
3676 GETKEY command instead of INFO command. Affected file
3677 lib/silcclient/command.c.
3679 * All command reply functions in the client library now calls
3680 the pending command reply callbacks even if an error has
3681 occurred. The server has done this a long time and now it was
3682 time to move the client library to this as well. Now all
3683 errors can be delivered back to the pending command reply
3684 callbacks if necessary. Affected files are
3685 lib/silcclient/command[_reply].[ch].
3687 * Change the nickname on disconnection back to the username
3688 because in reconnect the server will enforce it to it anyway.
3689 Affected file irssi/src/silc/core/silc-servers.c.
3691 * Fixed a config file parsing bug in the Irssi SILC client.
3692 Affected file irssi/src/silc/core/clientconfig.c.
3694 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * When printing the channel mode on JOIN, verify that the
3697 channel key and channel's HMAC are valid. Affected file
3698 irssi/src/silc/core/client_ops.c.
3700 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3703 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3704 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3706 * Removed channel key rekey task deleting from the function
3707 silc_server_save_channel_key. Affected file silcd/server.c.
3708 Added explicit timeout task context instead that is used to
3709 delete the task if we are registering a new task before the
3710 new task has elapsed.
3712 * When channel key rekey occurs the client library now saves
3713 the old channel key for a short period of time (10 seconds) and
3714 is able to use it in case some is still sending channel
3715 messages encrypted with the old key after the rekey. Affected
3716 file lib/silcclient/[idlist.h|client_channel.c].
3718 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Added check to the silc_server_new_id_real to not accept
3721 new ID if it is the sender's own ID. Affected file is
3722 silcd/packet_receive.c.
3724 * Assure that we do not announce ourself or the one we've
3725 sending our announcements when we're router and are announcing
3726 servers to our primary router. Affected file silcd/server.c.
3728 * Fixed silc_server_command_identify_check_client to assemble
3729 correct WHOIS packet. It send corrupted WHOIS packet and
3730 caused problem with router to router connections. Affected
3731 file silcd/command.c.
3733 Fixed also silc_server_command_whois_check the same way
3734 as for the IDENTIFY command.
3736 * Added new SilcIDListStatus to the server in the SilcIDListData
3737 structure. The status now includes the current status of
3738 the entry (like registered, resolved etc.). Affected file
3739 silcd/idlist.[ch]. Defined a bunch of different status types
3740 as well. This replaced the old boolean registered field as well.
3742 Added resolve_cmd_ident field to the SilcClientEntry structure
3743 too so that if the entry is for example being resolved so
3744 another command may attach to the same pending command reply
3745 without requiring to resolve the same entry again. This concept
3746 should optimize the WHOIS and the IDENTIFY resolving under
3747 heavy load by taking away unnecessary resolving for entries
3748 that are being resolved already.
3750 Added support for adding multiple pending commands for one
3751 command idenfier. Affected file silcd/command[_reply].[ch].
3753 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3754 before deleting the data. Otherwise the hash table will have
3755 freed data in comparison functions. Affected file is
3756 silcd/command_reply.c.
3758 * Fixed silc_idlist_replace_client_id to add the new entry to
3759 the cache with NULL nickname. Otherwise there will be invalid
3760 memory as the nickname after the nickname is freed. Affected
3761 file silcd/packet_receive.c.
3763 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3764 saved into wrong slots because the previous number of entries
3765 was not taken into account. Affected file silcd/idlist.c.
3766 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3768 * If we are router and we receive JOIN notify to a channel that
3769 does not have any users then notified client is marked as the
3770 channel founder, as it is it. The affected file is
3771 silcd/packet_receive.c
3773 * Added to the extended hash table API's table_del_*ext functions
3774 the destructor as argument too, so that the caller can decide
3775 which destructor to use or whether to use destructor at all.
3776 Affected file lib/silcutil/silchashtable.[ch].
3778 * Fixed ID Cache purging. It actually deleted the entries from
3779 the hash table after the data was freed. The hash table ended
3780 up comparing freed memory. The affected file is
3781 lib/silccore/silcidcache.c.
3783 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3785 * Fixed Irssi SILC client's KILL command's HELP syntax.
3787 * The USERS command now resolves the detailed user information
3788 if the userinfo field is missing. Affected file is
3789 lib/silcclient/command_reply.c.
3791 * Do not print error in silc_file_read if the read file does
3792 not exist. Just silently return NULL. Affected file is
3793 lib/silcutil/silcutil.c.
3795 * Fixed the silc_log_output to not wine about NULL filename
3796 and to not create some bogus " " filename. Affected file is
3797 lib/silcutil/silclog.c.
3799 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Fixed various printing bugs on the user interface in the
3802 Irssi SILC Client. Minor changes that were forgotten from
3805 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3807 * Fixed the configure.in.pre and the compilation and distribution
3808 environment to support the new autoconf 2.52. That version is
3809 now required to compile the CVS trunk.
3811 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3813 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3814 to generally parse user@fqdn format strings. Affected file
3815 lib/silcutil/silcutil.c.
3817 * Added nickname_format and nickname_force_format fields to the
3818 SilcClientParams structure. The first one defines the format
3819 for the nicknames that the library will enforce if the receives
3820 multiple same nicknames. The second one is boolean value and
3821 can be used to force the library to always enforce the format
3822 to the nicknames regardles whether there are multiple nicknames
3823 or not. This configurable formatting was employed to flexibly
3824 support accessing multiple nicknames from the user interface.
3825 The userinterface can now set the nicknames to what ever format
3826 they prefer. Affected file lib/silcclient/silcapi.h.
3828 Added function silc_client_nickname_format to the file
3829 lib/silcclient/idlist.c. It performs the nickname formatting.
3831 Added new field `hostname´ to the SilcClientEntry context.
3832 It holds the hostname of the client. Affected file is
3833 lib/silcclient/idlist.h.
3835 * Irssi SILC Client sets the nicknames in nick@hostn format.
3836 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3837 irssi/src/silc/core/silc-core.c.
3839 The WHOIS printing now also shows both the real nickname and
3840 the formatted nickname so that user knows how to access the
3841 user if there are multiple same nicknames cached. Affected
3842 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3843 printing formatting too to take the hostname now as a separate
3844 argument. The Affected file is
3845 irssi/src/fe-common/silc/modules-formats.[ch].
3847 * Changed the silc_client_get_clients_local to accept the formatted
3848 nickname as argument. It accepts the real nickname too but the
3849 formatted nickname can be used to find the true entry from
3850 multiple entries. Affected file lib/silcclient/silcapi.h and
3851 lib/silcclient/idlist.c.
3853 * Added nickname_format_parse field to the SilcClientParams.
3854 It is a callback function provided by the application to parse
3855 the nickname out of the formatted nickname string. The library
3856 calls it to get the nickname from the formatted string. Since
3857 the application generally knows better the format of the nickname
3858 string it parses it instead of the library, even though library
3859 encodes the formatted string. If the callback function is not
3860 provided then the library will use the string as is. The
3861 affected file is lib/silcclient/silcapi.h.
3863 * All the nickname strings passed to the client library in
3864 commands are now expected to be formatted nickname strings.
3865 If the command does not support the formatted nickname string
3866 it will assume that the sent string is the actual nickname.
3867 Affected file lib/silcclient/command.c.
3869 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Added public key authentication support to OPER and SILCOPER
3872 commands in the client library. Affected file is
3873 lib/silcclient/command.c.
3875 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3877 * Changed the get_auth_methdod client operation to be asynchronous.
3878 It can be async if the application resolves the authentication
3879 method from the server during the negotiation. Added new
3880 SilcGetAuthMeth completion callback that the application will
3881 call after resolving the authentication method.
3883 Added function silc_client_request_authentication_method that
3884 the application can use to resolve the authentication method
3885 from the server. Added also SilcConnectionAuthRequest callback
3886 that the library will call after the server has replied. The
3887 application can call this function if it does not know the
3888 current authentication method.
3890 Affected files are lib/silcclient/client.c and
3891 lib/silcclient/silcapi.h.
3893 * The Irssi SILC client now automatically resolves the authentication
3894 method incase any configuration information is not present (and
3895 currently there never is). The affected file is
3896 irssi/src/silc/core/client_ops.c.
3898 * Fixed public key authentication from the client library.
3899 Affected file lib/silcclient/protocol.c. Changed also the
3900 protocol specification about the public key authentication in
3901 the connection authentication protocol. The actual data to be
3902 signed is now computed with a hash function before signing.
3904 * Fixed the public key authentication from the server as well.
3905 Affected file silcd/protocol.c.
3907 * Removed the mlock()'s from the memory allocation routines.
3908 Affected file lib/silcutil/silcmemory.c. The ./configure does
3909 not check anymore for the mlock(). Affected file is
3912 * Fixed USERS command in server to allow the execution of the
3913 command for private and secret channels if the client sending
3914 the command is on the channel. Affected file silcd/command.c.
3916 * Fixed silc_client_get_clients_local to return the clients
3917 count correctly. It could return wrong value. Affected file
3918 lib/silcclient/idlist.c.
3920 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3923 types. The assembler optimizations seemed not to like 64-bit
3924 data types. The assmebler optimizations thus are now enabled
3925 also for BSD systems as opposed to only enable them for Linux.
3927 * Do not check for threads at all on BSD systems. Affected
3928 file configure.in.pre.
3930 * Removed -n and -h options from the Irssi SILC Client since
3931 they are not used in silc.
3933 * Fixed the prime generation to assure that the first digit
3934 of the generated random number is not zero since our conversion
3935 routines does not like number strings that starts with zero
3936 digit. If zero digit is seen the random number is regenerated.
3937 This caused some corrupted RSA keys when the zero first digit
3938 was met. Affected file lib/silcmath/silcprimegen.c.
3940 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3942 * Fixed WIN32 configuration in the ./configure script.
3943 Fixed to include xti.h on environments that has it.
3944 Patches by Carsten Ilchmann and andrew.
3946 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Changed the silc_id_create_client_id to be collision
3949 resistant. It is now assured that there cannot be created
3950 two same client ID's. I suspect that some weird bugs in
3951 the server were actually caused by duplicate Client IDs.
3952 Affected file silcd/serverid.[ch]. A router receiving
3953 new ID now also assures and informs the sending server
3954 if the ID caused collision.
3956 * Changed the silc_id_create_channel_id to also assure that
3957 there are no collisions.
3959 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Statement about ignoring the Mutual Authentication flag when
3962 performing rekey with PFS was a bit misleading. It is ignored
3963 if it was set in the initial negotiation, it cannot be even
3964 set in the rekey. Fixed in the ke-auth draft. Started the
3965 new versions of the protocol drafts in the doc/.
3967 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3969 * Fixed a bug in silc_client_command_identify_save when saving
3970 new channel information. The channel name was no duplicated
3971 and caused crash on exit. Affected file is
3972 lib/silcclient/command_reply.c.
3974 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Fixed the getkey command handling in the server. Send just
3977 empty OK reply to the sender if the key could not be fetched
3978 (but everything else was ok, like the key just was not available).
3979 Changed the public key parameter to optional in the protocol
3980 specs so that empty OK reply can be sent. Affected file
3983 Added a message to Irssi SILC client to tell to user if the
3984 server did not return a public key.
3986 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3988 * Fixed a channel key regeneration bug. It registered new
3989 timeout tasks exponentially until all system resources were
3990 used. Affected file silcd/server.c.
3992 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Added the SILC Document generator to the scripts/silcdoc.
3995 It can be used to generate the Toolkit Reference Manual out
3996 of the source tree. Internally it will also use the RoboDoc
3997 generator now imported in util/robodoc.
3999 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4001 * Added couple of return's in rekey protocol if error orccurred
4002 during the protocol. The execution must be terminated.
4003 Affected file silcd/protocol.c. Also, terminate the protocol
4004 always with timeout.
4006 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * The client's Client ID was created initally from the wrong
4009 nickname (it could have been in format nick@host) in the
4010 silc_server_new_client. Affected file silcd/packet_receive.c
4012 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Added some SILC_LOG_ERROR's to various error conditions
4015 if client could not be added to ID cache. Affected files
4016 silcd/packet_receive.c and silcd/server.c.
4018 * When client's sock->user_data is freed, NULL also the
4019 client->router and client->connection pointers. Added check
4020 for these pointers being NULL to various places around the
4021 code. Affected file silcd/server.c.
4023 * Added client->data.registered == TRUE checks to various
4024 places around the code to assure that unregistered client's
4025 are not handled when it is not allowed. Affected file
4028 * Added `bool registered' fields to all
4029 silc_idlist_[server|client]_get_* routines to indicate whether
4030 the fetched client needs to be registered or not. Affected
4031 file silcd/idlist.[ch].
4033 * Add your own entry as registered to the ID cache in the
4034 server. Affected file server.c.
4036 * Fixed a bug in silc_server_new_server. The SilcServer was
4037 set as the new server's context instead of SilcServerEntry.
4038 This naturally caused some weird bugs.
4040 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Do not delete the channel rekey task when adding it
4043 for in silc_server_create_channel_key.
4045 * Changed the silc_server_create_channel_key to return
4046 TRUE or FALSE to indicate the success of the channel key
4049 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4051 * Fixed MSVC++ project files and added missing files to
4052 Makefiles under win32/.
4054 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4056 * Do not add TCP_NODELAY flag if the operating system
4057 does not have it defined. Affected files are
4058 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4060 * Fixed buffer overflow from Irssi SILC Client. Affected
4061 file irssi/src/fe-common/core/themes.c.
4063 * Fixed double free in client library in the file
4064 lib/silcclient/client.c when disconnecting from server.
4066 * Applied double free patch from cras to Irssi SILC client.
4067 Affected files irssi/src/core/[modules/expandos].c
4069 * Fixed the disconnection handling to Irssi SILC Client.
4070 The application must call silc_client_close_connection
4071 in ops->connect client operation in case of failure of
4072 the connection. Affected file is
4073 irssi/src/silc/core/client_ops.c.
4075 * Do not set sock->protocol to NULL in the function
4076 silc_client_close_connection after executing the protocol's
4077 final callback since the sock might not be valid anymore.
4078 Affected file lib/silcclient/client.c.
4080 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4082 * Do not enable SILC_THREADS if the linking with libpthread
4083 did not happen. Affected file configure.in.pre.
4085 * Added notion to protocol specification that server must
4086 verify the sent authentication payload with CMODE when
4087 setting the channel founder key. Implemented it to the
4088 server. Affected file silcd/command.c.
4090 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Added _EXTRA_DIST SILC distribution variable to the
4093 distributions file. It is used to conditionally add extra
4094 files or directories to the specific distribution. Affected
4095 files ./prepare, Makefile.am.pre and distributions.
4097 Removed the `_' from the start of the distribution names.
4100 * Added README.WIN32 for instructions to compile the Toolkit
4103 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * Fixed a double free in disconnection in the server. Affected
4106 file is silcd/server.c.
4108 * Fixed the lib/silcske/groups.c to work now also with GMP
4109 MP library. The string conversion did not work when using
4110 specific base and the base is indicated in the string as well.
4112 * Created win32/ directory which now includes MSVC++ specific
4113 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4114 It will appear only in the toolkit distribution
4116 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4118 * Changed the key material distribution function in case when
4119 the hash output is too short. The data is now concatenated
4120 a bit differently than it used to. Made the change to the
4121 SKE protocol specification.
4123 * Added better GMP detection to configure.in.pre. A patch
4126 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4128 * Fixed a minor bug in SKE that might cause some problem on
4129 some platforms. Affected file lib/silcske/silcske.c.
4131 * Added the cookie checking for initiator in the SKE. It checks
4132 that the responder returns the sent cookie unmodified. The
4133 affected file is lib/silcske/silcske.c. Added new SKE
4134 error type INVALID_COOKIE that can be sent during the
4135 negotiation. Fixed some memory leaks as well.
4137 * Added the "invalid cookie" error message to Irssi SILC client's
4140 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4142 * Added `task_max' field to the SilcClientParams to indicate
4143 the maximum tasks the scheduler can handle. If set to zero,
4144 default values are used. Affected file lib/silcclient/silcapi.h.
4146 * Fixed memory leaks in silc_client_close_connection. Affected
4147 file lib/silcclient/client.c.
4149 * Added silc_client_del_client_entry to client library to free
4150 all memory of given client entry. Affected file is
4151 lib/silcclient/idlist.[ch].
4153 * Added new functions silc_client_del_channel and
4154 silc_client_del_server to delete channel and server entries.
4155 Affected file lib/silcclient/[silcapi.h/idlist.c].
4157 * Removed silc_client_del_client_by_id from silcapi.h.
4159 * Fixed the INFO command to return the server's own info
4160 correctly when querying by Server ID. Affected file is
4163 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * Removed the non-blocking settings in WIN32 code in the
4166 silc_sock_[read/write] and added SleepEx instead. Affected
4167 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4168 of input data is now checked with FIONREAD and ioctlsocket.
4170 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4172 * Call silc_schedule_task_del_by_context in the
4173 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4174 Affected file lib/silccore/silcprotocol.c.
4176 * Call silc_protocol_cancel for active protocols in the
4177 silc_server_close_connection if the funtion
4178 silc_server_free_sock_user_data has not been called.
4179 Affected file silcd/server.c.
4181 * Generic tasks cannot be deleted using the del_by_fd
4182 task deleting function since generic tasks does not match
4183 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4185 * Added a notion to SILCOPER help file that the SILCOPER works
4186 only on router server, not on normal server.
4188 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4190 * Added for WIN32 support for the new scheduler as well.
4191 Affected file lib/silcutil/win32/silcwin32schedule.c.
4193 * Fixed the SHA1 implementation to work on various platforms.
4195 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4197 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4198 API. It is part of the scheduler now. Everything else is
4199 as previously but some functions has changed their names.
4200 Checkout the lib/silcutil/silcschedule.h for the interface.
4201 Updated all applications to use the new interface. Affected
4202 files are lib/silcutil/silcschedule.[ch].
4204 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4206 * Found a bug in the SKE implementation. The HASH value,
4207 specified by the protocol, was not computed correctly. The
4208 public key of the responder was not added to the computation
4209 even though it is mandatory. Affected file lib/silcske/silcske.c.
4210 This unfortunately causes incompatibilities with older
4211 clients and servers.
4213 * Added WIN32 specific network init and uninit functions:
4214 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4215 the Winsock2. Affected file lib/silcutil/silcnet.h and
4216 lib/silcutil/win32/silcwin32net.c.
4218 * Set the socket always to nonblocking mode on WIN32 after
4219 reading data or writing data. Affected file is
4220 lib/silcutil/win32/silcwin32sockconn.c.
4222 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4224 * Fixed various compilation problems under WIN32. Affected
4225 files lib/silcutil/win32/silcwin32thread.c and
4226 lib/silcutil/win32/silcwin32schedule.c.
4228 * Removed all _internal.h #includes from public header
4229 files. Internal headers must never be included from
4232 Removed also the lib/silcske/payload_internal.h file.
4234 * All include files that may be needed (public and some others
4235 included by the public headers) by application developers are
4236 now copied to the ./includes directory. It does not copy any
4237 internal headers. Affected file Makefile.defines.pre and all
4238 Makefile.am's under lib/ and subdirs.
4240 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4242 * Do not change the ~/.silc directory's permissions automatically.
4243 Affected file irssi/src/silc/core/clientutil.c.
4245 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * Do not cancel the protocol in silc_server_close_connection
4248 it might cause recursion. Now cancelled in the function
4249 silc_server_free_sock_user_data. Affected file silcd/server.c.
4251 * Fixed the silc_server_remove_clients_by_server to regenerate
4252 the channel keys correctly finally. Added also new function
4253 silc_server_remove_clients_channels to actually do it.
4254 Affected file silcd/server.c.
4256 * Fixed the silc_server_new_channel to not crash by giving
4257 wrong router to the new channel. Affected file is
4258 silcd/packet_receive.c.
4260 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4262 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4263 which is given as argument to the silc_client_alloc now.
4264 It can be used to configure the client and set various parameters
4265 that affect the function of the client.
4267 * The USERS command in server did not check whether the channel
4268 is private or secret. Affected file silcd/command.c.
4270 * Added new argument to the USERS command in protocol specification.
4271 The USERS command now can take the channel name as argument
4272 as well. Added support for this in client and server and
4273 updated the protocol specs.
4275 * Completed the GETKEY command in client. It can be now used
4276 to fetch also servers public key not only some clients.
4277 Affected files lib/silcclient/command[_reply].c.
4279 * Added silc_client_get_server to return server entry by the
4280 server name. Affected files lib/silcclient/silcapi.h and
4283 * Redefined the IDENTIFY command in protocol specification to be
4284 more generic. It now can be used to query information about
4285 any entity in the SILC Network, including clients, servers and
4286 channels. The query may be based either the entity's name
4287 or the ID. Added support for this in both client and server.
4289 Affected files silcd/command.c and lib/silcclient/command.c
4290 and command_reply.c.
4292 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4293 the _from_client and _from_server functions. Affected file
4296 * Added silc_client_get_channel_by_id_resolve to the file
4297 lib/silcclient/silcapi.h to resolve channel information by
4298 its ID. Added also silc_client_get_channel_by_id that
4299 does not resolve it from the server.
4301 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4303 * Added SilcServerEntry context into the client library
4304 to represent one server. The INFO command now allocates
4305 these to save the resolved server info. For now on the
4306 client library will also keep information about servers,
4307 connected and resolved with INFO.
4309 The INFO command now allocates the SilcServerEntry context
4310 and saves the server info there. The COMMAND_REPLY in
4311 the INFO now returns the parameters to application in
4312 same order as defined in the protocol specification.
4314 The entries are cached in the client->server_cache.
4316 * The INFO command is now issued after received the Client ID
4317 from the server. Affected file lib/silcclient/client.c.
4319 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4320 to the application as the mode changer might be server.
4321 It is guaranteed that NULL is not returned anymore to the
4322 application. Affected file lib/silcclient/client_notify.c.
4324 The ID Type is now also passed to the application so that
4325 it can check whether the returned entry is SilcClientEntry
4328 Added new function silc_client_get_server_by_id to return
4329 the server entry by ID. Affected files are the
4330 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4332 * Do not create the channel in the Irssi SILC Client when issuing
4333 the JOIN command but when received the sucessful JOIN command
4334 reply. Otherwise the channel might get created even though we
4335 could not join it. The Affected file is
4336 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4338 * Fixed a channel joining bug in router. The router must also
4339 check the channel modes, invite and ban lists etc. when serving
4340 the JOIN command sent by normal server. Affected file is
4341 silcd/command.c. The router now resolves the client's
4342 information from the server who sent the JOIN command if it
4343 does not know it, and processes the JOIN command only after
4346 * Changed the SilcCommandCb to take new argument; void *context2.
4347 Affected file lib/silccore/silccommand.h
4349 The second argument in the command callbacks in the server now
4350 includes the SilcServerCommandReplyContext if the command was
4351 called as pending command callback from the command reply.
4352 Otherwise it is NULL. When called as pending the status of the
4353 command reply will be checked and if it was erronous the
4354 error will be sent to the original sender of the command.
4355 This way the client always receives the error messages even
4356 though the server was actually the one who received the error
4357 when it resent the command to router, for example. Affected
4358 files silcd/command[_reply].[ch].
4360 * Fixed sending WHOWAS command's error message to client if
4361 the requested client could not be found. It was missing.
4364 * Changed the CMODE and CUMODE commands reply arguments in the
4365 protocol specification. The Channel ID is now sent in both
4366 of the commands to identify the channel. Implemented this
4367 new feature to the client and server. Affected files
4368 lib/silcclient/command_reply.c and silcd/command.c.
4370 * Made better checks for invite and ban lists in the JOIN
4371 command in server. Affected file silcd/command.c.
4373 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4375 * The server now performs the incoming host IP/DNS lookup
4376 using the silc_socket_host_lookup and thus does not block
4377 the server anymore. Affected file silcd/server.c.
4379 * Completed the multi-thread support for SILC Scheduler in
4380 the lib/silcutil/silcschedule.c.
4382 * Fixed the configure.in.pre to detect the pthread correctly
4385 * Fixed a deadlock in silc_task_queue_wakeup in the file
4386 lib/silcutil/silctask.c.
4388 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4390 * Added new function silc_schedule_wakeup that is used in
4391 multi-threaded environment to wakeup the main thread's
4392 schduler. It needs to be used when a thread adds a new task
4393 or removes a task from task queues. After waking up, the
4394 scheduler will detect the task queue changes. If threads
4395 support is not compiled in this function has no effect.
4396 Implemented the wakeup mechanism to both Unix and WIN32
4397 systems. Affected files are lib/silcutil/silcschedule.[ch],
4398 lib/silcutil/unix/silcunixschedule.c and the
4399 lib/silcutil/win32/silcwin32schedule.c.
4401 * Added new function silc_task_queue_wakeup to wakeup the
4402 scheduler by the specified task queue. Affected file
4403 lib/silcutil/silctask.[ch].
4405 * The silc_socket_host_lookup_start now wakes up the scheduler
4406 after adding the timeout task. Affected file is
4407 lib/silcutil/silcsockconn.c.
4409 * The silc_socket_host_lookup is synchronous now if the threads
4410 support is not compiled in. However, the callback is still
4411 called asyncronously through the scheduler, anyway. Affected
4412 file lib/silcutil/silcsockconn.c.
4414 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4416 * Added new function silc_socket_host_lookup to perform
4417 asynchronous IP and FQDN lookups for the socket connection.
4418 Affected files lib/silcutil/silcsockconn.[ch].
4420 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4422 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4423 that may or may not compile the mutex support in.
4425 Changed the silc_mutex_alloc interface. It allocates the
4426 mutex now to the sent pointer and returns TRUE or FALSE.
4428 Affected file lib/silcutil/silcmutex.h.
4430 * Wrote the SILC Task Queue interface to support multi-threads.
4431 Affected file lib/silcutil/silctask.[ch].
4433 * Wrote the SILC Scheduler to support multi-threads. Affected
4434 file lib/silcutil/silcschedule.c.
4436 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4438 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4439 in lib/silcutil/win32/.
4441 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4443 * Defined SILC Mutex API and SILC Thread API and implemented
4444 them for Unix. Affected files are
4445 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4446 lib/silcutil/unix/silcunixmutex.c and
4447 lib/silcutil/unix/silcunixthread.c.
4449 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4451 * Fixed the silc_server_remove_clients_by_server's channel
4452 key re-generation. The hash table handling was incorrect
4453 and would not work with many channels. Affected file is
4456 * Fixed some memory leaks around the server code.
4458 * Rewrote the silc_server_get_users_on_channel to support IPv6
4459 based Client ID's. Affected file silcd/server.c.
4461 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4462 specification. However, a separate document must be written
4463 to define the detailed signing procedure and the payload
4464 associated with the flag. Defined the flag to the
4465 lib/silccore/silcchannel.h as well.
4467 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4469 * Changed the dynamic tables to static size tables in the
4470 lib/silccrypt/silchmac.c.
4472 * Removed GCC dependencies from the code. A patch by cras.
4474 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4476 * Do not show the error "Error receiving packet bla bla"
4477 in server if it really was not an error (-2 means that reading
4478 is pending). Affected file silcd/server.c.
4480 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4482 * Fixed a possible crash in silc_server_remove_clients_by_server
4483 in silcd/server.c. Fixed there also some memory leaks.
4485 * Fixed the silc_idlist_replace_client_id. It could replace
4486 wrong key in the hash table. Affected file silcd/idlist.c.
4488 * Do not check whether there are global users on the channel
4489 if the channel->global_users is FALSE. Affected functions
4490 silc_server_remove_from_one_channel and
4491 silc_server_remove_from_channels in silcd/server.c. Also,
4492 do not check if the removed client is local as we can be
4493 sure that global client was not removed from the channel
4494 and checking for global users is not needed.
4496 * The silc_server_remove_clients_by_server now re-generates
4497 the channel keys correctly for those channels that had
4498 clients removed from them. Affected file silcd/server.c.
4500 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Found the reason of random crashes in the server. We weren't
4503 ignoring the SIGPIPE signal (which can be sent in write())
4504 and it crashed the server. Affected file silcd/silcd.c.
4506 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4508 * Assure that sock->user_data is not NULL in the function
4509 silc_server_packet_send in silcd/packet_send.c.
4511 * Disconnect the remote connection if it could not be added
4512 to any ID lists in the server. The affected file is
4515 * Check in silc_server_packet_send[_real/dest] that the
4516 socket is not disconnecting and ignore the data if it is.
4517 Affected file silcd/packet_send.c.
4519 * Define inline to __inline on native WIN32 compilation.
4520 Affected file includes/silcwin32.h.
4522 * Added some explicit type casts for inline code since MSVC
4523 require them. Affected files lib/silcutil/silcbuffer.h,
4524 lib/trq/silcdlist.h and lib/trq/silclist.h.
4526 * Print warning in log files from now on if the packet
4527 decryption fails. Affected file silcd/server.c.
4529 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4531 * Changed the `say' client operation's interface to accept
4532 new `type' argument to indicate the type of the message sent
4533 by the library. The application may filter the library's
4534 messages according the type. The affected file is the
4535 lib/silcclient/silcapi.h.
4537 * Added two new functions to lib/silcclient/silcapi.h:
4538 silc_client_del_client and silc_client_del_client_by_id.
4539 Affected file lib/silcclient/idlist.c.
4541 * Moved the clientincludes.h from includes/ to silc/ and
4542 serverincludes.h from includes/ to silcd/.
4544 * The modes for the CMODE and CUMODE are now passed as
4545 uint32 for application with COMMAND_REPLY. The affected
4546 file is lib/silcclient/command_reply.c.
4548 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4550 * /WHOIS without arguments shows client's own information.
4551 Affected file lib/silcclient/command.c.
4553 * Changed PING to not accept any arguments. The specs
4554 says that client can ping only the connected server so
4555 requiring an argument is not needed. Affected file is
4556 lib/silcclient/command.c.
4558 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4560 * Fixed a fatal bug in private message sending and reception
4561 encryption and decryption when using private message keys.
4562 The implementation was incorrect and did not follow the
4563 specification. It causd that some of the message were
4564 lost since it did not use the sending and receiving keys
4565 as the protocol suggests. This has been fixed and will cause
4566 incompatibilities with older clients when sending private
4567 message encrypted with private message keys. Affected files
4568 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4569 and various other in Irssi SILC Client.
4571 Added `responder' boolean argument to the functions
4572 silc_client_add_private_message_key[_ske] to indicate when
4573 the key is added as responder or initiator of the key
4576 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4578 * Removed the silc_ske_check_version function and created
4579 a SilcSKECheckVersion callback. Added also a function
4580 silc_ske_set_callbacks that is now used to set all SKE
4581 callbacks. The callback functions are not given to
4582 the SKE functions anymore, but this function is used to
4585 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4587 * Added `silc_version' argument to the silc_client_alloc
4588 to define the version of the application for the library.
4589 The library will use the version string to compare it
4590 against the remote host's (usually a server) version
4591 string. Affected file lib/silcclient/silcapi.h
4593 * Added the KE protocol context to Key Agreement context
4594 in client library so that we can abort the SKE if it
4595 is in process when we get timeout. Affected file is
4596 lib/silcclient/client_keyagr.c.
4598 * Do not resolve the client ID forever if it returns in the
4599 first time that such client does not exist. This was done
4600 for example with private message. Affected file is
4601 lib/silcclient/client_prvmsg.c.
4603 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4605 * Do not add regex.h for WIN32. The affected file
4606 includes/silcincludes.h.
4608 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4609 not work yet 100%. It generates the DLL's automatically
4610 when compiling with --with-win32 under cygwin.
4612 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4614 * lib/contrib/regex.c is not compiled on WIN32.
4616 * Added silc_net_get_socket_opt function to the
4617 lib/silcutil/silcnet.h.
4619 * Added includes/silcwin32.h for WIN32 specific includes
4622 * Do not use ptime structure or any of the posix process
4623 functions on WIN32 in lib/silccrypt/silrng.c.
4625 * Added silc_gettimeofday to provide generic function
4626 for struct timeval on all platforms. Added the function
4627 to lib/silcutil/silcutil.h.
4629 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4631 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4632 library as they clearly belong there. As a plus side we
4633 can make the actual socket connection routines platform
4636 Added also new generic function silc_socket_read and
4637 silc_socket_write (that used to be silc_packet_[read/write].
4638 The implementation of these are platform specific.
4640 * Added WIN32 specific routines of silc_socket_[read/write]
4641 to lib/silcutil/win32/silcwin32sockconn.c.
4643 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4645 * Added preliminary support for native WIN32 compilation under
4646 cygwin (using the -mno-cygwin option for GCC) to the
4647 ./configure.in.pre. The --with-win32 now prepares the
4648 compilation for native WIN32.
4650 * Rewrote the SILC Scheduler interface in the file
4651 lib/silcutil/silcschedule.h. The scheduler is now context
4652 based and does not have anymore any global static scheduler.
4653 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4654 and created lib/silcutil/win32 directory for WIN32 based
4657 * Added Unix specific network routines to the
4658 lib/silcutil/unix/silcunixnet.c and the old
4659 lib/silcutil/silcnet.c includes now only generic routines.
4661 Added WIN32 specific network routines to the
4662 lib/silcutil/win32/silcwin32net.c.
4664 * Added Unix specific utility functions from the
4665 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4667 * Added WIN32 SILC Scheduler to the file
4668 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4671 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Do not handle JOIN notify in the server if the target client
4674 is not registered (idata->registered == FALSE). The affected
4675 file is silcd/packet_receive.c.
4677 * Update the nickrec->founder in event_cumode in the Irssi SILC
4678 client. Affected file irssi/src/silc/core/silc-channels.c.
4680 * Fixed the CUMODE_CHANGE notify handling in the server when
4681 server and router are announcing their clients on channels.
4682 Now the mode changes are saved and notified correctly. The
4683 affected file is /silcd/packet_receive.c.
4685 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4686 They really did not replace the cache entry in the ID Cache.
4687 Now they do that. Affected file silcd/idlist.c.
4689 * Fixed the KICK notify handling in the Irssi SILC client to
4690 update the channel records so that the kicked client does not
4691 appear to be on the channel. The affected file is
4692 irssi/src/silc/core/silc-channels.c.
4694 * Always update the conn->current_channel when executing command
4695 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4697 * Fixed the KILL notify handling in Irssi SILC client to remove
4698 the killed client on all channels.
4700 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed the silc_parse_command_line to remove extra spaces
4703 from the start and end of the arguments. Affected file is
4704 lib/silcutil/silcutil.c.
4706 * Cancel and free any active protocol in the function
4707 silc_server_close_connection. Affected file silcd/server.c.
4709 * Cancel and free any active protocol in the function
4710 silc_client_close_connction. Affected file is
4711 lib/silcclient/client.c.
4713 * Do not execute the KILL command for clients that are in
4714 history (ie. they are not in the network). Affected file is
4717 * Fixed KILL notify handling, client does not crash anymore.
4718 Affected file irssi/src/silc/core/silc-channels.c.
4720 * Reduced the default packet buffer size from 2048 to 1024 in
4721 lib/silccore/silcpacket.c.
4723 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4724 counter to the SKE context that is incresed when the SKE library
4725 performs async operation outside the library. If the outside
4726 process frees the SKE context and FREED status will be set
4727 and the library will detect after the sync operation that the
4728 libary is freed. The affected files are
4729 lib/silcske/silcske[_status].[ch].
4731 * Resolve the client entry information in the function
4732 silc_client_channel_message to assure that NULL pointer is not
4733 passed as client entry to the application. */
4735 * Fixed the task timeout calculation to assure that there is
4736 never negative timeouts. The affected file is
4737 lib/silcutil/silcschedule.c.
4739 * Fixed the channel user mode notification sending in server.
4740 It was sent point-to-point to the router (or to server by router)
4741 but it needs to be destined to a channel. The routines now
4742 supports sending the channel user mode notifys to the channels
4743 when announcing clients and channels. Affected files are
4744 silcd/server.c and silcd/packet_receive.c.
4746 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4747 It did not actually replace the old channel entry in the cache.
4748 Affected file lib/silcclient/client_notify.c.
4750 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed a possible crash in silc_packet_send_prepare. It now
4753 assures always that there is enough space in the buffer and
4754 at the tail area of the buffer (for MAC).
4756 Fixed the inbound buffer reallocation in silc_packet_read.
4757 It was old code and did not handle the reallocation correctly.
4760 The affected file is lib/silccore/silcpacket.c.
4762 * Fixed buffer overflow in silc_parse_nickname in the file
4763 lib/silcutil/silcutil.c.
4765 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * make install generates new server keys only if there is not
4770 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4773 Added check that if the NOREPLY is set then we will not send
4774 the away message. This avoids infinite loop of away messages
4775 if both clients are away. The affected file is
4776 lib/silcclient/client_prvmsg.c.
4778 * Fixed client crash if /NICK was given without arguments.
4779 Affected file lib/silcclient/command.c.
4781 * Server does not send the invite list in INVITE command back
4782 to the client if the list was not altered. Added this notion
4783 to the protocol spec as well. Affected file silcd/command.c.
4785 Fixed possible crash in INVITE command by checking the
4786 value of silc_server_get_client_route command.
4788 * Fixed the INVITE notify type handling. The arguments are now
4789 taken in correct order and client does not crash. The affected
4790 file is irssi/src/silc/core/silc-channels.c.
4792 Removed the "Inviting xxx to channel" message from the
4793 client library away and let the application handle it.
4794 Affected file lib/silcclient/command.c. Added that message
4795 to Irssi SILC client's message formats.
4797 * Fixed CMODE command crash in client. It now checks the
4798 amount of arguments correctly and does not crash. The affected
4799 file is lib/silcclient/command.c.
4801 * Do not create new channel automatically in silc_channels_join
4802 but check whether the channel by that name already exists.
4803 Affected file irssi/silc/core/silc-channels.c.
4805 * Do not send the SERVER_SIGNOFF to router if the disconnected
4806 entity was the router. Affected file silcd/server.c.
4808 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4809 SILC client as it was missing from there.
4811 Added the handling of the KICK notify to the Irssi SILC client
4812 as it was missing. Added "you have been kicked" message to
4813 Irssi SILC client's message modules formats.
4815 Added the handing of the KILL notify to the Irssi SILC client
4816 as it was missing. Added the kill message module formats
4819 The affected file is irssi/src/silc/core/silc-channels.c.
4821 * The router did not save the channel mode the server announced.
4822 Affected file silcd/packet_receive.c.
4824 * Fixed a possible crash in INFO command in server. If the
4825 server did not provide the server info it crashed. Affected
4826 file silcd/command.c.
4828 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Fixed the GETKEY command in the server to check also the
4831 global list. Otherwise the GETKEY would not work correctly
4832 in normal SILC server. Affected file silcd/command.c.
4834 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Fixed GETKEY crash, it crashed if the command did not succseed.
4838 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4841 is now real and not just an macro interface to GMP.
4843 Removed the entire GMP from the source tree and imported new
4844 NSS MPI library instead. Reason for removing GMP is that it is
4845 extremely large and compiles extremely slow. The NSS MPI
4846 is only a few files and compiles in less than 10 seconds.
4847 The speed is also about the same as GMP. The MPI is imported
4848 to lib/silcmath/mpi.
4850 If the system has GMP installed we will still use the GMP.
4851 If it is not then the NSS MPI will be compiled.
4853 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Merged a long nickname (127 characters long) crash bugfix from
4856 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4858 * Merged a freed memory reference bugfix from Irssi CVS tree.
4859 Affected file irssi/src/core/commands.c.
4861 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added the server's public key sving and verification to the
4864 server when performing the SKE. This was missing and the
4865 remote server's (or router's) public key was accepted without
4866 checking whether we have it previously or trust it at all.
4867 Affected file silcd/protocol.c.
4869 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Check in the silc_server_timeout_remote if protocol is active
4872 and make sure that the protocol's final callback is called so
4873 that all memory if freed. Affected file silcd/server.c.
4875 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * silc_server_whois_send_reply crashed the server if the nickname
4878 was 127 characters long. Affected file silcd/command.c.
4880 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added sanity check to the silc_server_new_client. If the hostname
4883 is provided inside username then check that the provided hostname
4884 really is the same as the resolved one. If the hostname was not
4885 resolved then check it from the public key. Affected file is
4886 silcd/packet_receive.c.
4888 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4889 if the server disconnected us and the connection is not valid
4890 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4892 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4893 the library to the lib/silcutil/silcutil.[ch].
4895 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Close log file after open. Affected file
4898 lib/silcutil/silclog.c.
4900 * Check whether sock == NULL in silc_client_send_packet and return
4901 if it is. Affected file lib/silcclient/silcclient.c.
4903 * Check rec->entry == NULL in the Irssi SILC Client before
4904 sending the channel message. Affecte file is
4905 irssi/src/silc/core/silc-servers.c.
4907 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Merged a splitted window bugfix from Irssi CVS tree. The
4910 affected file is irssi/src/fe-text/textbuffer-view.c.
4912 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4913 It did not print nickname.
4915 * Improved the distributions system a bit.
4917 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4920 irssi/src/fe-text/gui-window.c.
4922 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4923 to in-active server. The affected file is
4924 irssi/src/silc/core/client_ops.c.
4926 * Resolve the client in USERS command reply if the entry does
4927 not have username resolved. The affected file is
4928 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4929 command to WHOIS command to really resolve stuff. The USERS
4930 is not used any more in any critical section so WHOIS can
4931 be used even though it might be slower than IDENTIFY.
4933 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4936 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Changed the protocol API a bit more consistent in the
4939 lib/silccore/silcprotocol.[ch].
4941 * Changed the following headers to ROBODoc format:
4943 lib/silccore/silcpayload.h
4944 lib/silccore/silcprotocol.h
4945 lib/silccore/silcsockconn.h
4947 All core library headers are now formatted.
4949 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Fixed a bug in Irssi SILC client; do not show that you are
4952 server/router operator if you really are not. Affected file is
4953 irssi/src/silc/core/client_ops.c.
4955 * Renamed silc_command_free_payload to silc_command_payload_free.
4956 Affected file lib/silccore/silccommand.h
4958 * Added silcmath.h to include the prototoypes of various routines
4959 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4962 * Changed the following headers to ROBODoc format:
4964 lib/silccore/silcchannel.h
4965 lib/silccore/silccommand.h
4966 lib/silccore/silcid.h
4967 lib/silccore/silcidcache.h
4968 lib/silccore/silcmode.h
4969 lib/silccore/silcnotify.h
4970 lib/silccore/silcpacket.h
4971 lib/silcmath/silcmath.h
4973 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Added checking to the server code not to start the server if
4976 ciphers and stuff are not configured properly. Affected files
4977 silcd/serverconfig.[h] and silcd/server.c.
4979 * Changed the layout of the header files of the public interfaces
4980 in the SILC libraries. The new layout supports ROBODoc
4981 documentation tool (and some others) so that it is easy to create
4982 a library reference manual. All the other headers and source
4983 code must still follow the CodingStyle document. Also source
4984 code must not include these ROBODoc stuffs, only the headers.
4985 Furthermore, all public interface headers must now be named
4986 by using `silc' prefix, example: silcapi.h, silccipher.h.
4987 Some files were renamed due to this. All the other headers
4988 must not be used as public interfaces. I will update the
4989 CodingStyle document later. Changed following headers, so far:
4991 lib/silcclient/silcapi.h
4992 lib/silccore/silcauth.h
4993 lib/silccore/silcprivate.h
4994 lib/silccrypt/silcdh.h
4996 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Removed silc_client_packet_send_flush from the client library
5001 as it is not needed. Affected file lib/silcclient/client.[ch].
5003 * Added printing of message of unresolved authentication method
5004 to the Irssi SILC client. Added it to the module formats.
5005 Removed the same message from the client library.
5007 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added new distribution feature, DISTLABEL. Every distribution
5010 can define own preprocessor label that can be used in the
5011 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5012 file distributions, acconfig.h.pre and prepare.
5014 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Added Makefile.defines_int to include the actual definitions
5017 for Makefile.defines.in. Tested the new distribution system,
5018 created distributions and tested installation.
5020 * Added AWAY message printing to the Irssi SILC client. Added
5021 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5023 * Added SCONNECT command to call the SILC's CONNECT command.
5024 Cannot use CONNECT directly since Irssi uses that internally.
5025 Affected file irssi/src/silc/core/silc-servers.c.
5027 Added ACTION local command. It is same as ME command but takes
5028 the channel as mandatory argument.
5030 Rewrote some of the Irssi's help files to suite for SILC
5033 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Added Makefile.defines[.in] that should for now on be included
5036 in all Makefile.am file in the source tree. That file includes
5037 all common compilation definitions for SILC source tree.
5039 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Minor changes to the ./prepare script to change the package
5042 name according the distribution name to the configure.in.
5044 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Created new distribution system. Added file `distributions'
5047 that defines all the distributions that can be created out of
5048 the SILC source tree. The ./prepare script now reads that
5049 file to determine how to prepare the distributions. The
5050 first argument to the ./prepare is the name of the distribution
5051 and second is the version of the distribution. If given
5052 without arguments it creates the default (toolkit) distribution
5053 with the default version (defined in ./prepare).
5055 All Makefile.am files that are subject to the distributions
5056 are now named as Makefile.am.pre. These are ./Makefile.am
5057 and lib/Makefile.am. Others may be changed later.
5059 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added invite list, ban list, some key management and connection
5062 error message printing to module formats in the Irssi SILC client.
5064 * Added new silc_client_set_away_message to set the away message
5065 that is back to the person who sent private message. The
5066 affected file lib/silcclient/silcapi.h and the
5067 lib/silcclient/client_prvmsg.c.
5069 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Fixed the private message sending in the Irssi SILC client,
5072 added local command KEY to the Irssi SILC client.
5074 Added key management and key agreement message formats to the
5075 irssi/src/fe-common/silc/module-formats.[ch].
5077 Added USERS (alias WHO) printing, server/router operator
5078 indication and LIST command printing to the module formats.
5080 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Fixed channel joining notify handling, cumode notify handling
5083 from Irssi SILC client.
5085 * Added SILC specific module-formats to the Irssi SILC client so
5086 that SILC specific message hilighting, colors etc is possible.
5087 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5089 Added channel mode, channel user mode, actions, notices,
5090 whois and whowas printing to the the module-formats.c.
5092 * Fixed a bug in channel deletion in the server. The channel
5093 is not left to the cache even if the channel founder auth mode
5094 is set when there are no users anymore on the channel. Affected
5095 file silcd/server.c.
5097 * The silc_net_localhost now resolves the entire hostname including
5098 the domain name. Affected file lib/silcutil/silcnet.c.
5100 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Changed the ask_passphrase client operation to be ascynchronous.
5103 It has now a completion callback and a context that the
5104 application must call after it has got the passphrase from
5105 the user. Affected files lib/silcclient/silcapi.h,
5106 lib/silcclient/protocol.c, lib/silcclient/command.c and
5109 Added SilcAskPassphrase callback that the application calls
5110 to deliver the passphrase to the library.
5112 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5113 The public key verification and especially a certificate
5114 verification is asynchronous procedure.
5116 Added new SILC_SKE_STATUS_PENDING status to indicate the
5117 request is pending and a callback will be called to finalize
5120 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5121 indicate that remote end did not send its public key (or
5122 certificate), even though we require it. Added check for this
5123 condition in the SKE. This was a security bug, now fixed.
5125 Defined new SilcSKEVerifyCbCompletion callback that is called
5126 when the verification process is completed.
5128 The affected files lib/silcske/silcske_status.h and
5129 lib/silcske/silcske.[ch].
5131 * Changed the verify_public_key client operation to be async
5132 as well. Defined SilcVerifyPublicKey callback that is used to
5133 indicate the success of the public key verification process.
5135 Changed the server and client to use the new async client
5138 * Changed the Irssi SILC client's internal scheduler to be called
5139 twice as many times as it used to be. As a result the client
5140 should be a bit faster now. Affected file is
5141 irssi/src/silc/core/silc-core.c.
5143 * Added support to Irssi SILC client of asynchronous public key
5144 verification and passphrase inquiry. Affected file is
5145 irssi/src/silc/core/silc-core.c.
5147 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Do not say "You have left channel %s" in client library.
5150 Moved it to the application. Affected files are
5151 lib/silcclient/command.c and silc/client_ops.c.
5153 * Fixed silc_client_get_clients. Command context was not
5154 duplicated and was freed memory in the callback. Affected
5155 file lib/silcclient/idlist.c.
5157 * Do not say "you are now talking..." on JOIN command in the
5158 client library. The appliation must handle it.
5160 * Do not say ".. changed topic to" in command reply in the
5161 client libary. The application must handle it.
5163 * Fixed TOPIC command sending in the client library.
5165 * Fixed a memory leak in silc_client_command_free in the file
5166 lib/silcclient/command.c.
5168 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Imported a modified version of Irssi client to the source tree.
5171 The Irssi will be used to create a new client called
5172 Irssi SILC. Imported to irssi/.
5174 Added silc_core_init_finish function to the Irssi. Affected
5175 file irssi/configure.in.
5177 A lot changes in the Makefile.ams around the irssi tree.
5179 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Do not rehash if the new size is same as the old size of the
5182 hash table, in the silc_hash_table_rehash*. The affected file
5183 lib/silcutil/silchashtable.c.
5185 * Replaced hash_table_del_by_context calls from the server
5186 (when channel->user_list and client->channels) to the
5187 hash_table_del as it is sufficient and faster.
5189 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Added silc_hash_table_list, silc_hash_table_get and the
5192 SilcHashTableList structure to provide an alternative way to
5193 traverse the hash table. The affected files are
5194 lib/silcutil/silchashtable.[ch].
5196 * Changed the server's idlist routines to use the hash table
5197 routines to optimize the code.
5199 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Replaced the client entry's `channel' list and channel entry's
5202 `user_list' list to hash tables for optimized lookup. Changed
5203 the code to use the hash table interface around the code.
5204 Affected file lib/silcd/idlist.[ch].
5206 * Added `auto_rehash' boolean argument to the function
5207 silc_hash_table_alloc to indicate whether the hash table should
5208 auto-rehash when it thinks is appropriate time. It will
5209 increase the hash table size if the there is twice as much
5210 entries in the table than the size of the table, and will
5211 decrease the size if there are twice as less entries than
5212 the size of the table.
5214 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5218 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * silc_idcache_purge_by_context deletes the entry now by context
5221 as it is supposed to do. Affected file lib/silccore/idcache.c.
5223 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5224 client is not anymore valid (WHOWAS givens the info) and not
5225 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5227 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Removed the `data' and `data_len' arguments from the ID Cache
5230 interfaces and added `name' argument. ID Cache does not handle
5231 anymore the binary data only a names associated with given ID.
5233 * When hashing a Client ID with silc_hash_id the entire ID is
5234 not hashed anymore, instead only the hash of the Client ID is
5235 hashed. This way we can access the Client ID from the cache
5236 with Client ID but with the hash of the ID (which is a hash of
5237 the nickname) as well without any difference in performance.
5239 Added also silc_idcache_find_by_id_one_ext to do one on one
5240 searching when we have the actual ID. Added also function
5241 silc_hash_client_id_compare. The affected files are
5242 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5244 * When hashing the name associated with a ID it is always done
5245 in lowercase. This way we can access the cache without worrying
5246 about case-sensitivity, even though, for example nicknames are
5249 * Fixed a bug in server with channel message sending. It put
5250 wrong ID type as destination ID. The affected file
5251 silcd/packet_send.c.
5253 * silc_idcache_del_by_context now deletes from all hash tables
5254 by context. Affected file lib/silccore/idcache.c.
5256 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Changed the client library to use the new ID Cache interface.
5259 Changes around the source tree.
5261 * Added silc_hash_table_rehash_ext to rehash with specific
5262 hash function. Affected file lib/silcutil/silchashtable.[ch].
5264 * Added silc_hash_string_compare to compare two strings in the
5265 hash table. Affected file lib/silcutil/silcutil.[ch].
5267 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added new function silc_idcache_del_by_context into the
5270 lib/silccore/idcache.[ch].
5272 * Changed the server's ID list routines to use the new ID Cache
5273 interface. Changes around the source tree.
5275 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Added silc_hash_table_del[_by_context]_ext functions in to the
5278 lib/silcutil/silchashtable.[ch].
5280 Removed silc_hash_table_find_all* routines and added new
5281 silc_hash_table_find_foreach to replace them.
5283 Added silc_hash_table_replace_ext function as extended
5284 replacing function. Separated the simple hash table interface
5285 from the extended hash table interface in the file
5286 lib/silcutil/silchashtable.h.
5288 * Fixed minor bugs and changed it to use some of the new
5289 hash table functions in lib/silccore/idcache.c
5291 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added new function silc_hash_table_find_all to return all keys
5294 in the hash table by the specified key. As the hash table is
5295 collision resistant it also makes it possible to have several
5296 duplicate keys in the hash table. This function may be used to
5297 find all of the keys from the hash.
5299 Added user_context arguments to the SilcHashFunction,
5300 SilcHashCompare and SilcHashDestructor to deliver user specified
5303 Added new fuctions silc_hash_table_find[_all]_ext to do
5304 extended lookup with specified hash and compare functions and
5305 specified user contexts.
5307 Added new function silc_hash_table_add_ext to add the key
5308 with specified hash function and user context.
5310 Added new function silc_hash_table_foreach to traverse all
5311 entrys in the hash table. Added SilcHashForeach callback
5314 Added new function silc_hash_table_del_by_context to delete
5315 the entry only if the context associated with the key matches.
5317 Affected files are lib/silcutil/silchashtable.[ch].
5319 * Removed silc_hash_[server/client/channel]_id and added just
5320 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5321 silc_hash_id_compare to compare two ID's using as the hash table
5322 comparison function. Added also silc_hash_data to hash
5323 binary data and silc_hash_data_compare to compare it.
5325 * Removed silc_idlist_find_client_by_hash as it is not needed
5326 anymore. Affected file silcd/idlist.[ch].
5328 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5329 to use internally the SilcHashTable. The new ID Cache is a lot
5330 faster than the old one. Some of the ID Cache interface was also
5331 rewritten and obsolete and stupid functions were removed.
5333 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Added entry_count field to the SilcHashTable to keep the number
5336 of the entries in the table. Implemented the function
5337 silc_hash_table_rehash. Added new function
5338 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5340 Fixed a minor bug in silc_hash_table_free.
5342 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5343 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5344 into the lib/silcutil/silcutil.[ch].
5346 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Implemented a collision resistant hash table into the
5349 lib/silcutil/silchashtable[ch]. See the header and the source
5350 for the SilcHashTable API.
5352 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Merged dotconf version 1.0.2 into lib/dotconf.
5356 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Do not compile anything in lib/silcsim/* if the SIM support
5359 is not enabled. The tree should now compile without problems
5362 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Compiled the SILC under cygwin. Compiled and tested briefly
5365 without problems. More tests needed. The SIMs didn't compile
5368 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5370 * Fixed possible crash in silc_get_username in the
5371 lib/silcutil/silcutil.c.
5373 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Fixed a va_arg in silc/client_ops.c.
5377 * Oops, RC5 routines were named AES and caused some problems
5378 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5380 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added new SilcIDIP structure into the lib/silccore/id.h and
5383 replaced the old `ip' fields from all SILC ID's to that type.
5384 This is a step towards IPv6 support.
5386 The silc_id_get_len takes now the ID as an extra argument.
5387 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5388 both IPv4 and IPv6 based ID's.
5390 The affected files are lib/silccore/id.[ch] and other files
5391 around the tree using these routines.
5393 * Removed the ID length arguments in server from various
5394 silc_server_send_notify_* routines -> they are not needed
5397 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Fixed memory leak in silc_encode_pem_file in the file
5400 lib/silcutil/silcutil.c.
5402 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Check minor version as well in the SKE. Affected files are
5405 silcd/protocol.c and lib/silcclient/protocol.c.
5407 * Added --identifier option to the server so that an identifier
5408 can be when creating the public key for the server. Affected
5409 file is silcd/silcd.c.
5411 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5412 lib/silccrypt/silcpkcs.c.
5414 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Register default ciphers and stuff when using -C option with
5417 the server. Affected file sildc/silcd.c.
5419 * Put back the servers public key filename format, it is better
5420 than the new one. For now, the client keys are saved with the
5421 new filename format. The affected file silc/client_ops.c.
5423 * Implemented the Cipher API for the rest of the ciphers that
5424 did not implement it or implemented it the wrong way.
5426 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Register default ciphers and stuff when using the -S option
5429 in the client. Affected file silc/silc.c. Same also when
5430 creating new key pair with -C option.
5432 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Fixed the silc_verify_public_key client operation function to
5435 save the public keys differently. The fingerprint is now
5436 used as filename and not the hostname. This way also the
5437 client keys are saved uniquely and not with hostnames. The
5438 affected file is silc/client_ops.c.
5440 * Trimmed the silc_hash_fingerprint function to remove extra
5441 whitespaces from the end of the fingerprint. The affected
5442 file is lib/silccrypt/silchash.c.
5446 * Added silc_cipher_register_default function to register all
5447 default ciphers. It can be used when configuration files
5448 does not exist and the application does not want any specific
5449 ciphers in any specific order.
5451 The SilcDList is now used as silc_cipher_list dynamically
5452 allocated cipher list. Removed the static list all together
5453 and now all ciphers must be allocated to the dynamic list.
5454 The silc_cipher_alloc routine was changed to check only the
5457 All silc_cipher_* routines that used to return int returns
5460 The affected files lib/silccrypt/silccrypt.[ch].
5462 * The same thing was done to silc_hash_* as for silc_cipher_*
5463 routines. Affected files lib/silccrypt/silchash.[ch].
5465 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5466 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5467 Added also silc_pkcs_[un]register[_default] functions.
5468 Removed the data_context from the PKCS API.
5470 * Added silc_hmac_register_default function to register default
5471 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5472 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5473 to unregister all hmacs at once.
5475 * Register the default ciphers, hash functions, PKCSs and HMACs
5476 if client's configuration file does not exist. The affected
5479 * The client did not load the hash functions from the SIM
5480 modules at all. Added support for this. Affected file is
5481 silc/clientconfig.c.
5483 * When decoding public key with silc_pkcs_public_key_decode, check
5484 the supported algorithm only if PKCS are registered. Affected
5485 file lib/silccrypt/silcpkcs.c. The same was done with the
5486 silc_pkcs_private_key_decode.
5488 * Fixed the SILC List routines to keep the list always in order.
5489 It used to change the list's order when traversing the list but
5490 not it preserves the order. Affected file lib/trq/silclist.h.
5492 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Added the client library to use the SilcSocketConnection's
5495 reference counter (by silc_socket_dup) to prevent the bug that
5496 the socket object may be freed underneath async operation.
5498 * The name resolv library checking fixes in the configure.in.pre.
5501 * Created new version of the protocol drafts for future
5502 development. The -03 drafts are the ones that will be changed
5503 in the trunk now and the -02 will remain as they are.
5505 * Send list of CUMODE notifys to the router when announcing
5506 the channel users to the router. Affected file silcd/server.c.
5507 If the router receiving channel founder CUMODE for a channel
5508 that already has channel founder it will send CUMODE notify
5509 to the sender to remove the channel founder rights from the
5510 announced client. Affected file silcd/packet_receive.c.
5512 * The CUMODE notify may now use Server ID as well as the entity
5513 who changes the mode. Updated protocool specs.
5515 * Updated INSTALL and README files.
5517 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * New web pages in the http://silc.pspt.fi. The pages was
5524 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Implemented the [DenyConnectin] config section in the server.
5527 Added silc_server_config_denied_conn to check whether incoming
5528 connection is denied. Affected file silcd/serverconfig.[ch].
5530 * Do not check the ports when checking the incoming configuration
5531 data if the port is 0, meaning any. Affected file is
5532 silcd/serverconfig.c.
5534 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Fixed buffer overflow in silc_string_compare in the file
5537 lib/silcutil/silcutil.c.
5539 * Fixed double free in silc_server_command_leave in the file
5542 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Fixed the version checking in the server. Affected file is
5547 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Fixed the configuration data fetching when accepting new
5550 connections in the server. Affected file silcd/server.c.
5552 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Added `sender_entry' argument to the function
5555 silc_server_packet_relay_to_channel so that we can check
5556 whether some destination actually belongs to the same route
5557 the sender belongs (ie, we must not resend the packet to the
5558 sender). Affected file silcd/packet_send.[ch].
5560 * Added `servername' field to the SilcClientEntry in the server
5561 to hold the name of the server where client is from. Affected
5562 file is silcd/idlist.h.
5564 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Moved the channel message encrypting in the router betwen
5567 router connections from silc_server_channel_message to the
5568 silc_server_packet_relay_to_channel since we want to check
5569 whether we have anybody channel before encrypting anything.
5570 Affected files silcd/packet_[receive/send].c.
5572 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Fixed the [AdminConnection] server config section to support
5575 multiple entries. Affected file silcd/serverconfig.c.
5577 * Added support into the server to check the validity of the
5578 incoming connection before executing any KE or authentication
5581 * The connection configuration is now saved to the KE and
5582 connection auth protocol contexts and not fetched anymore in
5583 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5585 * The local hosts listenning address and port is also resolved
5586 now when starting the server. We want to have the socket object
5587 to include the real address and port for the listener. Added
5588 new function silc_net_check_local_by_sock into the files
5589 lib/silcutil/silcnet.[ch].
5591 * Fixed a broadcast bug in server -> do not broadcast if we
5594 * Fixed a routing bug. Do not route broadcast packets ever.
5595 Broadcast packets must be processed always and not routed since
5596 they may be destined to some other host than yourself and thus
5597 would get routed without no good reason. Affected file is
5600 * Added function silc_server_config_is_primary_route to check
5601 whether primary router connection has been configured (a router
5602 configuration that we are initiating). If there is not, we
5603 will assume that there is only two routers in the SILC network
5604 and we will use the incoming router connection as our primary
5605 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5607 * Changed the order of the broadcasting. Broadcast _after_ the
5608 packet has been processed not before. Affected file is
5611 * Fixed a [ClientConnection] parsing bug. The port was never
5612 parsed correctly thus resulting to port 0. Affected file
5613 silcd/serverconfig.c.
5615 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5616 argument and did not set the broadcast packet flag. Affected
5617 file silcd/packet_send.c. Fixed same bug in the function
5618 silc_server_send_notify as well.
5620 * If we receive NEW_ID packet for our own ID in the server, ignore
5623 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Removed the nickname from the Private Message Payload.
5628 Updated the code and the protocol specs.
5630 * Updated protocol specs for submitting to the IETF.
5632 * Tweaked the Random Number Generator a bit. Affected file
5633 lib/silccrypt/silcrng.c. Exported a new function
5634 silc_rng_[global]_add_noise which can be used to add more
5637 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Do not parse packets with different timeout when protocol
5640 is active -> may cause problem with rekey. Affected file
5643 * When server receives signoff notify it must not create
5644 new channel key if the client is on any channels since the
5645 sender of the signoff notify will create it.
5647 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added printing of error messages during SKE protocol from the
5650 failure packet sent by server during SKE. Affected file
5653 * Removed the client's failure_callback handling with timeout
5654 and handle it immediately when received.
5656 * The SKE library returned wrong type in SUCCESS and FAILURE
5657 packets. They must be 32 bit MSB not 16 bit MSB.
5659 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Ok, rewrote the logic of the re-key and now it seems to work.
5662 I tested it on high traffic with frequent re-keys without
5663 problems. Added hmac_receive (and renamed hmac to hmac_send)
5664 in SilcClientConnection in lib/silcclient/client.h and
5665 in SilcIDListData in silcd/idlist.h. Also, removed the
5666 SilcPacketParserContext's cipher and hmac fields as they are
5667 not needed anymore and actually caused some problems when
5668 the ciphers and hmac's changed underneath the packet parser.
5670 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * If re-key protocol is active then process the incoming packets
5673 synchronously since we must assure that icoming packets encrypted
5674 with the old key is processed before the new keys is set to
5675 use. This is true other packets than for REKEY packets.
5676 Affected file silcd/server.c. The same was done to client library
5677 as well, affected file lib/silcclient/client.c.
5679 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Fixed bug in client and server to accept the force send if
5682 the packet is send from silc_[server/client]_packet_process
5683 function. Otherwise the packets are never delivered, oops.
5685 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Disable force sending of packets when REKEY protocol is active.
5688 We must assure that no packet is sent directly when rekey is
5689 performed. All packets must be sent through packet queue.
5690 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5691 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5692 function is silc_[server/client]_packet_send_real to check
5695 * Replaced the SIM paths from example config files to
5696 /usr/local/modules. Also, make install creates now
5697 /usr/local/silc/logs directory to hold all the SILC server
5700 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Made the configure.in.pre work on Solaris. Patch by salo.
5704 * Made all ciphers compatible with non-x86 machines. Defined
5705 CBC mode macros into lib/silccrypt/ciphers_def.h.
5707 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Fixed the make install.
5711 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * When MAC computation fails the silc_packet_decrypt returned 0
5714 even though it was supposed to return -1. Fixed this. The
5715 affected file is lib/silccore/silcpacket.c.
5717 * Do not replace the config files in /etc/silc (in make install)
5718 if they already exist. Affected file ./Makefile.am.
5720 * Do not send re-key packets immediately but through packet queue.
5721 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5723 * Changed silc_net_check_host_by_sock to return FALSE if the
5724 IP/DNS could not be resolved. Though, it returns the IP address
5725 now even if it could not resolve it (but returns also FALSE).
5726 Affected file lib/silcutil/silcnet.[ch].
5728 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Added silc_pkcs_decode_identifier to decode the public key's
5731 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5732 Added also silc_pkcs_free_identifier. Added also new context
5733 SilcPublicKeyIdentifier.
5735 * Added -S option to the silc client. It is used to dump the
5736 contents of the specified public key file.
5738 * Changed the PKCS api to return the public key length when
5739 setting the public key.
5741 * Fixed a fatal bug in the public and private key file loading.
5742 Affected file lib/silccrypt/silcpkcs.c.
5744 * Execute the packet parsing for client with zero (0) timeout
5745 if the protocol is active. Affected file silcd/server.c.
5747 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Made the key generation options to the silcd program. Added
5750 -C option, equivalent to client's option.
5752 * Added new [ServerKeys] config section to the server. It
5753 configures the server's public and private key.
5755 * Defined generic Public Key Payload into the protocol
5756 specification to send specific type of public keys and
5759 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5760 public key or certificate.
5762 * Implemented the GETKEY command to the server and to the

5771 * Added SilcServerRekey context into silcd/idlist.h.
5773 * Added the PFS support as defined in the specification to the
5774 SKE protocol. Affected files lib/silcske/*.c.
5776 * Added `ske_group' field to the SilcServerRekey context to hold
5777 the number of the SKE group that is used with PFS in re-key.
5778 Affected file silcd/idlist.h.
5780 * Added PFS re-key support to the server. Affected file is
5783 * Added silc_protocol_cancel to cancel execution of the next
5784 state of the protocol. Affected file is
5785 lib/silccore/silcprotocol.[ch].
5787 * Added the re-key support with and without PFS to the client
5788 library. Re-key is performed once in an hour, by default.
5790 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5791 Added silc_client_rekey_callback and silc_client_rekey_final.
5792 Affected files are lib/silcclient/protocol.[ch] and
5793 lib/silcclient/client.[ch].
5795 * Removed the `hmac_key' and `hmac_key_len' fields from the
5796 SilcClientConnection structure; not needed. Affected file is
5797 lib/silcclient/client.h.
5801 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Do not ask whether user wants to use the negotiated private key
5804 for private messages, just use it. Affected file is
5805 silc/local_command.c.
5807 * Added `send_enc_key' and `enc_key_len' fields to the
5808 SilcIDListData structure since they are needed in the re-key
5809 phase. Affected file is silcd/idlist.[ch].
5811 * Implemented the simple re-key protocol into the server.
5812 Affected files silcd/server.c and silcd/protocol.[ch]. The
5813 re-key will be performed once in an hour, by default.
5815 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5816 Added silc_server_rekey, silc_server_rekey_callback and
5817 silc_server_rekey_final.
5819 * Removed Tunneled flag from the protocol. Updated the code
5820 and the specifications.
5822 * Adde `pfs' field to the SilcIDListData to indicate whether
5823 the PFS is to be performed in the re-key. Affected file is
5826 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5829 int64 of at least the xintXX size. If void * is less that 4
5830 bytes uint32 * will be used. Defined bool as boolean.
5832 * Changed _ALL_ unsigned long and unsigned int to uint32,
5833 unsgined short to uint16 in the source tree.
5835 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5836 not handle clients that has entry->data.registered == FALSE.
5837 They are not in the network anymore. Affected file is
5840 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Implemented the sending of the SERVER_SIGNOFF notify in the
5843 server. Affected file is silcd/server.c.
5845 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5846 Added also silc_notify_payload_encode_args into the
5847 lib/silccore/silcnotify.[ch].
5849 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5850 Affected file silcd/packet_receive.c.
5852 * Implemented the SERVER_SIGNOFF notify handling in the client
5853 library. Affected file lib/silcclient/client_notify.c. Also,
5854 implemnted the printing of the SERVER_SIGNOFF info to the
5855 application. Affected file silc/client_ops.c.
5857 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5858 if the deleting was successful. Affected file silcd/idlist.[ch].
5860 * Added support for public key authentication in the connection
5861 authentication protocol in the client library. Affected file
5862 lib/silcclient/protocol.c.
5864 * Changed the server's silc_idlist_get_clients_by_* interface
5865 to support already allocated array so that new entries may be
5866 added to pre-allocated array. Affected file silcd/idlist.[ch].
5867 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5868 and command replies.
5870 * All command reply functions in the server now calls the
5871 pending command callback even if error occured. This way the
5872 error will be delivered to the client as well. Affected files
5873 silcd/command.c and silcd/command_reply.c.
5875 * Fixed INFO command to return local server's info if no server
5876 was provided. Affected file lib/silcclient/command.c.
5878 * Removed RESTART command for good. Updated the code and the
5881 * Rewrote parts of the task system. It is a bit simpler now.
5882 Removed unsued task priorities. The affected files are
5883 lib/silcutil/silctask.[ch].
5885 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Moved the USERS printing from the library to the application.
5888 Affected files lib/silcclient/command.c and silc/client_ops.c.
5890 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added channel key re-key support. The re-key is perfomed
5895 only by the router and is done once in an hour. Added `rekey'
5896 field to the SilcChannelEntry in the server. Affected files
5897 silcd/server.c and silcd/idlist.h.
5899 * Added silc_task_unregister_by_context into the file
5900 lib/silcutil/silctask.[ch].
5902 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Added SILC_UMODE_GONE mode to indicate when the client is not
5905 present in the SILC network. Added also support to the local
5906 command AWAY that will set this mode. Added support of showing
5907 "xxx is gone" in WHOIS command. The USERS command shows the
5908 gone status as well.
5910 * Fixed setting server and router operator privileges in the
5911 server's UMODE command. Affected file silcd/command.c.
5913 * Merged the SKE KE1 and KE2 payloads into one payload. The
5914 new KE payload is equivalent to the old KE2 payload.
5916 Cleaned up the SKE Start Payload parsing. It now uses the
5917 simple buffer unformatting to do the parsing. A lot faster
5920 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5921 to the SKE that is used to indicate whether both of the SKE
5922 parties should perform authentication. By default only the
5923 responder performs authentication. By setting this flag also
5924 the initiator must do authentication. By default it is unset
5925 since in normal SKE case, client to server connection, only
5926 the responder should do authentication. When doing SKE between
5927 two clients both should perform authentication. Updated the
5928 code and the protocol specs.
5930 * A little fix to IDENTIFY command in the server. Search the
5931 client first by hash not nickname. Affected file is
5934 * Fixed the silc_client_close_connection to support closing
5935 the client to client connections wihtout deleting too much
5936 data. Affected file lib/silcclient/client.c.
5938 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5939 are received if protocol used to be active but is not anymore
5940 the application would crash due to NULL pointer dereference.
5941 Affected files silcd/server.c and lib/silcclient/client.c.
5943 * Added `hash' field to the SilcClientConnection to include
5944 the hash function negotiated in the SKE protocol.
5946 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5947 to set the channel founder authentication data. A client can
5948 claim the founder rights later by providing the authentication
5949 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5950 This way the channel founder can regain the channel founder
5951 privileges even it is left the channel. This works only on
5952 local server and the client must be connected to the same
5953 server to be able to regain the founder rights. Updated the
5954 protocol specs accordingly.
5956 Added support to the CMODE command in the client to set the
5957 founder auth data. Read the README to see how to set it.
5959 Added support to the CUMODE command to claim the founder
5960 rights. Read the README to see how to do it.
5962 Added support for the founder authentication to the Channel
5963 Entry in the server. Affected file silcd/idlist.h.
5965 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5966 server's CMODE command. Affected file silcd/command.c.
5968 * Added the following new functions into lib/silccore/silcauth.[ch]:
5969 silc_auth_get_method and silc_auth_get_data.
5971 * The server now saves the remote hosts public key to the
5972 SilcIDListData pointer. Affected file silcd/protocol.c.
5974 * The normal server now does not remove the channel entry from
5975 the cache if the founder authentication data is set. It used
5976 to remove it if the founder was the last one on the channel on
5977 the server and left the channel. The auth data is saved and
5978 if the channel is re-joined later the old entry is used with
5979 the old auth data. Affected files silcd/command_reply.c and
5982 * Removed the `pkcs' field from the SilcIDListData structure
5983 in the server; it is not used. Affected file silcd/idlist.h.
5985 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Fixed packet processing on slow links. Partial packets were
5988 never re-processed because the incoming data buffer was cleared
5989 by the application. Application must not directly clear the
5990 sock->inbuf, the packet processing routines handle it. Fixed
5991 this in client library and in server.
5993 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Fixed the WHOIS and IDENTIFY send reply function to really
5996 check whether to send list or just one entry. Affected file
5999 * Cleaned up the LEAVE command's channel key distribution. The
6000 affected file silcd/command.c.
6002 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6003 can enforce the channel mode as well. In that case the ID
6004 includes the ID of the server. The code now enforces the
6005 mode change if the router have different mode than the server.
6007 * The notify client operation with CMODE_CHANGE notify can now
6008 return NULL client_entry pointer if the CMODE was not changed
6009 by client. Application must check for this.
6011 * Added <Server ID> argument to INFO command to support server
6012 info fetching by Server ID.
6014 * Added silc_server_announce_get_channel_users to get assembled
6015 packets of channel users of the specified channel. Affected
6016 file silcd/server.[ch].
6018 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6019 was freed underneath the ID Cache.
6021 * Re-announce clients when the server received CHANNEL_CHANGE
6022 notify from the router. Affected file silcd/packet_send.c.
6024 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6027 crashed since it did not handle the fact that there is no cipher
6028 called "3" and didn't check the error condition. Now fixed.
6030 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6031 flag. It can be used to send message requests.
6033 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Implemented the RESTART command in the client.
6037 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6038 notice type messages. Added notice printing to the user
6041 * The channel keys are not re-generated if the channel's mode
6042 is PRIVKEY, ie private key on the channel exists. Affected
6043 files silcd/server.c and silcd/command.c.
6045 * Fixed a little bug in channel message delivery when channel
6046 private keys are set in the server. Affected file is
6047 silcd/packet_send.c.
6049 * Changed the setting on channel->on_channel = TRUE from the
6050 silc_client_save_channel_key to the JOIN command reply. The
6051 key payload is not received if the private channel key is set.
6052 Affected file lib/silcclient/command_reply.c and the
6053 lib/silcclient/client_channel.c.
6055 * When the CMODE_CHANGE notify is sent and the channel private
6056 key mode is removed the channel key must be re-generated in
6057 other cells as well. Added this support for the router in the
6058 silcd/packet_receive.c.
6060 * Added new local command NOTICE to send notice message on
6061 channel. Affected file silc/local_command.[ch].
6063 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Added new local command ME to the client. It is used to send
6066 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6067 some action. Affected file silc/local_command.[ch].
6069 * Changed channel_message and private_message client operations
6070 to deliver the message flags to the application. Added also
6071 the `flags' arguments to the silc_client_send_channel_message
6072 and silc_client_send_private_message functions. Affected file
6075 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Redefined the Private Message Payload to support private message
6078 keys and to support the new private message flags. Updated
6079 the protocol specs. Flags makes it possible to have for example
6080 CTCP style messages.
6082 * Added new type SilcPrivateMessagePayload and defined an API
6083 for it in the lib/silcclient/silcprivate.[ch].
6085 * Tested private message private keys successfully. Tested the
6086 private message key set, unset and list commands with the new
6089 * Redefined the Channel Message Payload to include the channel
6090 message flags (equal with private message flags) to support
6091 for example CTCP style messages.
6093 * Defined some of the message (for channel and private message)
6094 flags. Updated the protocol specs and added the flags to the
6095 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6097 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Added SilcKeyAgreementStatus type to the key agreement routines
6100 to indicate the current status and error if one occured.
6101 The status types are defined in the lib/silcclient/silcapi.h.
6103 * Added new local command KEY that is used to set and unset private
6104 keys for channels, set and unset private keys for private messages
6105 with remote clients and to send key agreement requests and
6106 negotiate the key agreement protocol with remote client. The
6107 key agreement is supported only to negotiate private message keys,
6108 it currently cannot be used to negotiate private keys for channels,
6109 as it is not convenient for that purpose.
6111 * Fixed a minor pending callback setting bug in the function
6112 silc_client_get_client_by_id_resolve, now the function works.
6113 Affected file lib/silcclient/idlist.c.
6115 * Added function silc_net_get_local_port to get local bound
6116 port by socket. Added to lib/silcutil/silcnet.[ch].
6118 * Added `sockets' and `sockets_count' fields to the SilcClient
6119 object. They hold the sockets of the listenning sockets in
6120 the client. Listenning sockets may be for example the key
6121 agreement server. Affected file lib/silcclient/client.[ch].
6122 Added functions the silc_client_add_socket and the
6123 silc_client_del_socket. They are exported to the application
6126 * Added ~./silc/clientkeys to support other client's public keys.
6128 * Renamed verify_server_key client operation to verify_public_key
6129 and added one argument to indicate the type of the connection
6130 (server, client etc.).
6132 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Added silc_server_connection_auth_request to handle the
6135 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6136 silcd/packet_receive.[ch].
6138 * Added silc_server_send_connection_auth_request into the
6139 silcd/packet_send.c to send the connection auth request packet.
6141 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6144 * Fixed the public key authentication in responder side in the
6145 server. The `auth_data' pointer includes the SilcPublicKey
6146 not the path to the public key. Affected file silcd/protocol.c.
6148 * Implemented the public key authentication in the initiator side
6149 in the server. Affected file silcd/protocol.c.
6151 * Removed the [RedirectClient] config section from the server
6152 configuration. Is not needed and I don't want to implement it.
6154 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Cleaned up the CMODE command in the server. It now works
6157 correctly and supports all the modes defined in the protocol.
6158 Affected file is silcd/command.c.
6160 * Added `hmac_name' field to the SilcChannelEntry in the server
6161 to hold the default HMAC of the channel. It can be set when
6162 creating the channel (with JOIN command). Affected files
6165 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6166 type to indicate the change of the current cipher and hmac
6167 on the channel. Client can safely ignore the <cipher> argument
6168 (if it chooses to do so) since the CHANNEL_KEY packet will
6169 force the channel key change anyway. The <hmac> argument is
6170 important since the client is responsible of setting the new
6171 HMAC and the hmac key into use.
6173 * Fixed the CMODE command in the client library as well.
6175 * Tested CMODE command in router environment successfully.
6177 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Show the version of the remote client (or server) when connecting
6180 to the server. It is logged to the log file. Affected file
6181 is silcd/protocol.c.
6183 * Fixed the KILLED notify handling in the client library. The
6184 client must be removed from all channels when receiving the
6187 Also, do not remove the client entry when giving the KILL
6188 command but when the KILLED notify is received.
6190 * Removed silc_idlist_find_client_by_nickname from the server.
6191 Not needed anymore. Affected files silcd/idlist.[ch].
6193 * Implemented the CHANNEL_CHANGE notify type handling to the
6194 server. Affected file silcd/server.c.
6198 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added silc_server_send_notify_invite to send the INVITE
6201 notify between routers.
6203 * Implemented the INVITE command correctly to the server.
6205 * Implemented the INVITE notify type handling in the server.
6207 * Implemented the INVITE command to the client library and on the
6210 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Added function silc_server_get_client_resolve to find the
6213 client entry by ID from all ID lists and then resolve it
6214 (using WHOIS) if it cannot be found. Affected file is
6217 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Implemented the BAN command to the client library.
6221 * The JOIN command in the server now checks the invite list
6224 * Changed the silc_command_reply_payload_encode_va and the
6225 silc_command_payload_encode_va to support that if argument is
6226 NULL it ignores and checks the next argument. Affected file
6227 lib/silccore/silccommand.c.
6229 * Added silc_server_send_notify_ban to send the BAN notify
6230 type between routers.
6232 * Chaned the silc_notify_payload_encode to support that if
6233 argument is NULL it ignores and checks the next argument.
6234 Affected file lib/silccore/silcnotify.c.
6236 * Tested ban lists in router environment successfully.
6238 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Implemented BAN command to the server, in silcd/command.[ch].
6242 * Removed the BAN and INVITE_LIST modes from the CMODE command
6245 * Added function silc_string_match to regex match two strings.
6246 Affected files lib/silcutil/silcutil.[ch].
6248 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Redefined parts of the SilcChannelEntry in the server to support
6251 the new ban and invite lists.
6253 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Redefined the INVITE command. The same command can be used to
6256 invite individuals to the channel but also to manage the invite
6257 list of the channel (to add to and remove from the invite list).
6258 Updated the protocol specs.
6260 * Added new command SILC_COMMAND_BAN that can be used to manage
6261 the ban list of the channel. Updated the protocol specs.
6263 * Removed the channel modes: the SILC_CMODE_BAN and the
6264 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6265 in the CMODE command. The equivalent features are now available
6266 using INVITE and BAN commands. Updated the protocol specs.
6268 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6269 in the network about change in the current ban list. The notify
6270 type is not used by the client.
6272 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6273 support the invite lists.
6275 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Added new function silc_string_regexify that converts string
6278 including wildcard characters into regex string that can
6279 be used by the GNU regex library. Added into the file
6280 lib/silcutil/silcutil.[ch].
6282 Added silc_string_regex_combine to combine to regex strings
6283 into one so that they can be used as one regex string by
6284 the GNU regex library. Added into the file
6285 lib/silcutil/silcutil.[ch].
6287 Added silc_string_regex_match to match two strings. It returns
6288 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6290 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Imported GNU regex to the soruce tree into lib/contrib.
6293 Fixed some compiler warning from the regex.c.
6295 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Fixed MOTD command in the server to work in router environment.
6299 * Fixed the MOTD command in the client library to support
6300 the server argument in the command.
6302 * Added `nickname_len' argument to the silc_idlist_add_client
6303 in the server, as the `nickname' argument may be binary data
6306 * Added silc_idlist_get_channels to return all channels from
6309 * Implemented LIST command to the server. Affected file is
6312 * Implemented the LIST command to the client library and on the
6315 * Added [<user count>] argument to the LIST command reply.
6316 With private channels the user count is not shown.
6318 * Updated TODO and README.
6320 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * The client entry's data.registered must be TRUE even with
6323 global client entry on global client list. The data.registered
6324 is used to check whether the client is anymore in the network,
6325 for example with WHOWAS command so it must be valid.
6327 * Fixed the WHOWAS command in the server. It now actually works
6328 in router environment. Added function into silcd/command_reply.c
6329 silc_server_command_reply_whowas_save.
6331 * Added silc_idlist_purge function to the silcd/idlist.c
6332 to periodically purge the ID Cache.
6334 * Fixed INFO command in the server. It works now in router
6335 environment. Added <server name> argument to the INFO command
6336 reply. Updated the protocol specs.
6338 * Fixed minor bug in silc_idcache_purge to not purge if the
6339 expire value is zero.
6341 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6342 they were buggy because of the WHOWAS information.
6344 * Fixed local command MSG to handle the async resolving of
6345 the remote client properly. It used to fail the first MSG.
6346 Affected file silc/local_command.c.
6348 * Added `data_len' field to SilcIDCache context.
6350 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Update TODO. Todo in commands in the server.
6354 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6357 used by routers as broadcast packet to inform other routers
6358 about the changed user mode.
6360 Implemented the notify handling in the server. Affected file is
6361 silcd/packet_receive.c. Added the function
6362 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6364 * Added new generic Channel Payload and deprecated the New Channel
6365 Payload. The New Channel Payload is now the generic Channel
6368 * Added new argument `mode' to the silc_server_send_new_channel
6369 as it is required in the Channel Payload now.
6371 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6372 and created a new and real SilChannelPayload to represent the
6373 new generic Channel Payload. Implemented the encode/decode
6374 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6376 * Added silc_server_get_client_channel_list to return the list
6377 of channels the client has joined for WHOIS command reply.
6378 Affected file silcd/server.[ch].
6380 * Implemented the channel list sending in the WHOIS command reply
6381 in server and in the client.
6383 Implemented the channel list displaying on the user interface
6384 as well. Affected file silc/client_ops.c.
6386 * Added silc_channel_payload_parse_list to parse list of Channel
6387 Payloads. It returns SilcDList list of SilcChannelPayloads.
6388 Client for example can use this function to parse the list of
6389 channels it receives in the WHOIS command reply. The caller
6390 must free the list by calling silc_channel_payload_list_free.
6391 Affected files lib/silccore/silcchannel.[ch].
6393 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Added one new argument <user mode> to the WHOIS command reply
6396 to return the mode of the user in SILC. Updated the protocol
6399 Implemented it to the server and client.
6401 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Fixed the mode printing on the user interface on joining.
6404 Affected file silc/client_ops.c.
6406 * Implemented the UMODE command and user modes in general to the
6407 client library and to the user interface.
6409 * Implemented the UMODE command to the server.
6411 * The server now sends UNKNOWN_COMMAND error status if client sends
6412 unknown command. Affected file silcd/command.c.
6414 * All server commands now handle the command identifier the right
6415 way when sending the command reply to the client. The client can
6416 use to identify the command replies with the identifier.
6418 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Added silc_server_get_client_route to resolve the route to
6421 the client indicated by the client ID. Affected file is
6424 * Added silc_server_relay_packet as general function to relay
6425 packet to arbitrary destination. This deprecates functions
6426 like _send_private_message_key, _relay_notify etc. Affected
6427 file is silcd/packet_send.[ch].
6429 Removed silc_server_send_key_agreement,
6430 silc_server_send_private_message_key and
6431 silc_server_packet_relay_notify functions from the file
6432 silcd/packet_send.[ch].
6436 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6437 server. Affected file silcd/packet_receive.[ch].
6439 * Implemented the KILL command to the client. Implemented the
6440 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6441 Affected files lib/silcclient/command[_reply].c and
6442 lib/silcclient/client_notify.c. Implemented the KILL notify
6443 printing in the user inteface.
6445 * Fixed a lot silc_parse_nick memory leaks from the client
6446 library in the file lib/silcclient/command.c.
6448 * Changed the silc_server_send_notify_on_channels's `sender'
6449 argument from SilcSocketConnection to SilcClientEntry to
6450 check the sender as entry and not as connection object and not
6451 to send to the client provided as argument. The affected file
6452 is silcd/packet_send.[ch].
6454 * The notify packets that are destined directly to the client used
6455 to not to be processed by the server. Now changed that and the
6456 server processes all notify packets. After relaying the packet
6457 to the client the notify packet is processed in the server.
6459 * The silc_server_free_client_data now checks whether there is
6460 pending outgoing traffic for the client and purges the data to
6461 the network before removing the client entry.
6463 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6466 an client is killed from the SILC Network. Updated the protocol
6469 Added new function silc_server_send_notify_killed to the
6470 silcd/packet_send.[ch].
6472 * Added function silc_server_packet_relay_notify to relay notify
6473 packets that are destined directly to a client. In this case
6474 the server does not process the notify packets but merely relays
6475 it to the client. Affected file silcd/packet_send.[ch].
6477 Added also silc_server_packet_process_relay_notify to check
6478 whereto relay the notify. Affected file is
6479 silcd/packet_receive.[ch].
6481 * Implemented the KILL command to the server.
6485 * Added the backup schema desgined last fall to the protocol
6486 specs for everyone to see. The specification is in the
6487 *-spec-xx.txt draft and the packet type definitions for the
6488 backup routers is in *-pp-xx.txt draft. Thusly, added also
6489 new packet type SILC_PACKET_CELL_ROUTERS.
6491 * A big security problem in the implementation discovered. The
6492 signoff of an client did not cause new channel key generation
6493 which it of course should've done. The channel keys must be
6494 always re-generated when client leaves (or signoffs) the channel.
6495 The silc_server_remove_from_channels funtion now handles
6496 the channel key re-generation.
6498 * Added `sender' argument to the silc_server_send_notify_on_channels
6499 to not to send the client provided as argument. Affected file
6500 silcd/packet_send.[ch].
6502 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Implemented OPER and SILCOPER commands into the server and
6507 * Added silc_auth_verify and silc_auth_verify_data to verify
6508 the authentication directly from the authentication payload.
6509 It supports verifying both passphrase and public key based
6510 authentication. Affected file lib/silccore/silcauth.[ch].
6512 * Added `hash' field to the SilcIDListData structure. It is the
6513 hash negotiated in the SKE protocol. Affected file is
6516 * Slight redesigning of the SilcAuthPayload handling routines.
6517 Do not send SilcPKCS but SilcPublicKey as argument.
6519 * Implemented the public key authentication support to the
6520 serverconfig. The public key is loaded from the provided path
6521 and saved as authentication data to void * pointer. Thus,
6522 changed the unsigned char *auth_data to void *auth_data;
6524 * Fixed SHUTDOWN command to send the reply before the server
6525 is shutdown. :) Affected file silcd/command.c.
6527 * Fixed fatal bug in CONNECT command. The hostname was invalid
6528 memory and server crashed. Affected file silcd/command.c.
6530 * Fixed fatal bug in CLOSE command. The server_entry became
6531 invalid but was referenced later in the command. Affected file
6534 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Fixed fatal bug in failure packet handling. Server ignored
6537 the failure and thus crashed when it came.
6541 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6544 that the command may be executed only once in (about) 2 seconds.
6545 The old SILC_CF_LAG flag is same but allows command bursts up
6546 to five before limiting.
6548 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6549 server code. Various commands now includes the CF_LAG_STRICT
6550 flag to disallow any kind of miss-use of the command.
6552 * Fixed the silc_buffer_unformat to not to allocate any data
6553 if the length of the data is zero. It used to allocate the
6554 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6556 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Changed the format of AdminConnection configuration section
6559 in the server. Added username of the admin to the format.
6560 Affected files silcd/serverconfig.[ch].
6562 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6563 to return admin configuration data by host, username and/or
6566 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Implemented WHOWAS command to the server. Added the functions:
6570 silc_server_command_whowas_parse,
6571 silc_server_command_whowas_send_reply,
6572 silc_server_command_whowas_from_client and
6573 silc_server_command_whowas_from_server
6575 * Added <Client ID> argument to the WHOWAS command reply. Updated
6576 the protocol specs accordingly.
6578 * Implemented WHOWAS command and command_reply to the client
6581 Implemented the WHOWAS printing on the user interface.
6583 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added new argument to the WHOWAS command reply, the real name.
6586 It is an optional argument. Updated the protocol specs.
6588 * Added SilcIDCacheDestructor callback that is registered when
6589 the SilcIDCache is allocated. The callback is called when
6590 an cache entry in the ID Cache expires, or is purged from the
6591 cache. Added into lib/silccore/idcache.[ch].
6593 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6594 to destruct the client entries when the cache entry expires.
6595 Other ID Cache's in server and in the client library ignores
6598 * If the ID Cache entry's `expire' field is zero then the entry
6599 never expires. Added boolean `expire' argument to the
6600 silc_idcache_add function in the lib/silccore/idcache.[ch].
6601 If it is TRUE the default expiry value is used.
6603 * Added silc_server_free_client_data_timeout that is registered
6604 when client disconnects. By default for 5 minutes we preserve
6605 the client entry for history - for WHOWAS command.
6607 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added support to the server to enforce that commands are not
6610 executed more than once in 2 seconds. If server receives
6611 commands from client more frequently, timeout is registered
6612 to process the commands. Affected file silcd/command.c.
6613 Added new function silc_server_command_process_timeout.
6615 * Changed NICK_NOTIFY handling in client library to check that
6616 if the client's nickname was changed, so there is no need to
6617 resolve anything from the server.
6619 * Removed error printing from the WHOIS and IDENTIFY commands.
6620 If error occurs then it is ignored silently in the client library.
6621 The application, however, may map the received error to
6622 human readable error string. The application currently maps
6623 the NO_SUCH_NICKNAME error to string.
6625 * Made the command status message public to the application. Moved
6626 them from lib/silcclient/command_reply.c to
6627 lib/silcclient/command_reply.h. The application can map the
6628 received command status to the string with the
6629 silc_client_command_status_message function.
6631 * Added check to the server to check that client's ID is same
6632 as the Source ID in the packet the client sent. They must
6635 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Added dist-bzip hook to the Makefile.am to make bzip2
6638 compressed distributions.
6640 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Server now enforces the maximum length for the nickname and
6643 the channel as protocol specification dictates. 128 bytes for
6644 nickname and 256 bytes for channel name.
6646 * Moved the WHOIS printing to the application. The client libary
6647 does not print out the WHOIS information anymore, the application
6648 must do it. Renamed silc_client_command_reply_whois_print to
6649 the silc_client_command_reply_whois_save.
6651 The client's idle time is also sent to the application now, and
6652 the idle is shown on screen.
6654 * Added silc_client_command_reply_identify_save to save the
6655 received IDENTIFY entries.
6657 * Do not check for channel private keys in message sending and
6658 reception if the channel does not have the PRIVKEY mode set.
6659 Affected file lib/silclient/client_channel.c.
6661 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6664 just surfaced after chaning the JOIN procedure.
6666 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Added silc_client_get_clients_by_list to get client entries
6669 from Client ID list, that is returned for example by JOIN
6670 and USERS command replies. The application should use this
6671 function for example when JOIN command reply is received to
6672 resolve the clients already on the channel (library does not
6673 do that anymore as USERS command reply is not used in the JOIN
6674 procedure anymore). Affected files lib/silcclient/silcapi.h and
6675 lib/silcclient/idlist.c.
6677 * JOIN command reply and USERS command reply returns now SilcBuffer
6678 pointers instead of unsigned char pointers when returning
6679 the client list and mode list.
6681 * Added <Client ID> argument to the JOIN command reply, mainly
6682 for the server to identify for which client the command was
6683 originally sent. Updated protocol specs accordingly.
6685 * Added SilcDlist private_key pointer to the SilcChannelEntry
6686 in the client to support the channel private keys. Affected
6687 file is lib/silcclient/idlist.h.
6689 * Added SilcChannelPrivateKey argument to the function
6690 silc_client_send_channel_message so that application can choose
6691 to use specific private ke if it wants to. If it is not provided,
6692 the normal channel key is used, unless private keys are set.
6693 In this case the first (key that was added first) is used
6694 as the encryption key.
6696 * Implemented the support for channel private key handling.
6697 Implemented the following functions:
6699 silc_client_add_channel_private_key,
6700 silc_client_del_channel_private_keys,
6701 silc_client_del_channel_private_key,
6702 silc_client_list_channel_private_keys and
6703 silc_client_free_channel_private_keys
6705 Affected file lib/silcclient/client_channel.c.
6707 * Added the support for the private keys in the channel message
6708 sending and encryption and in the message reception and
6709 decryption. Affected funtions are
6710 silc_client_send_channel_message and silc_client_channel_message.
6712 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added SKE's key verify callback to the client library's
6715 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6717 * Removed the statement that server (or router) must send USERS
6718 command reply when joining to the channel so that the client
6719 knows who are on the channel. Instead, the client list and
6720 client's mode list is now sent in the JOIN command reply to the
6721 client who joined channel. This is better solution.
6723 * Added function silc_server_get_users_on_channel and function
6724 silc_server_save_users_on_channel to the silcd/server.[ch].
6726 * Removed function silc_server_command_send_users from the
6729 * Do not show topic on the client library anymore. The topic is
6730 sent in the command reply notify to the application and the
6731 application must show the topic now.
6733 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added client searching by nickname hash into the IDENTIFY and
6736 WHOIS commands in the server as they were clearly missing from
6737 them. Affected file is silcd/command.c.
6739 * Fixed a bug in private message receiving in the client library.
6740 The remote ID was freed and it wasn't supposed, now it is
6743 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Minor fix to the channel payload; allocate the data area, as it
6746 needs to be of specific length.
6748 * If the key agreement port is zero then the operating
6749 system will define the bound port. Affected files are
6750 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6752 * Added new function silc_channel_payload_decrypt into the file
6753 lib/silccore/silcchannel.[ch].
6755 * Moved the channel message etc, check from silc_packet_decrypt
6756 to applications. The library calls now a generic
6757 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6758 when the packet is either normal or special. This was done to
6759 allow more wide range of checking that was not allowed when
6760 the code was in library. Now applications can do virtually any
6761 checks to the packet and return to the library the decision how
6762 the packet should be processed. Affected files are
6763 lib/silccore/silcpacket.[ch].
6765 Added silc_server_packet_decrypt_check to the server and
6766 silc_client_packet_decrypt_check to the client library.
6768 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6769 to send with specified source and destination information.
6771 * Channel message delivery between routers was broken after the
6772 channel key distribution was fixed earlier. The channel key
6773 was used be to distributed to other routers as well which is not
6774 allowed by the protocol. Now this is fixed and channel keys
6775 really are cell specific and the channel message delivery between
6776 routers comply with the protocol specification.
6778 * Fixed various commands in server to check also the global list
6779 for the channel entry and not just the local list. The affected
6780 file silcd/command.c.
6782 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * Added assert()s to buffer formatting and unformatting routines
6785 to assert (if --enable-debug) when error occurs. Affected
6786 file: lib/silcutil/silcbuffmt.c.
6788 * Changed to auto-reconnect to check whether the remote host is
6789 router and register the re-connect timeout if it is. It used
6790 to check that whether we are normal server, but router must do
6791 auto-reconnect with another router as well. Affected file
6794 * Removed the [<key len>] option from CMODE command as the cipher
6795 name decides the key length, nowadays. See the defined ciphers
6796 from the protocol specification.
6798 * Added [<hmac>] option to the CMODE command to define the HMAC
6799 for the channel. Added SILC_CMODE_HMAC channel mode.
6801 * Added [<hmac>] option for the JOIN command so that user can
6802 select which HMAC is used to compute the MACs of the channel
6805 * Added Hmac field to the Channel Message Payload. The integrity
6806 of plaintext channel messages are now protected by computing
6807 MAC of the message and attaching the MAC to the payload. The
6808 MAC is encrypted. Now, it is clear that this causes some
6809 overhead to the size of the packet but rationale for this is that
6810 now the receiver can verify whether the channel message decrypted
6811 correctly and also when private keys are set for the channel the
6812 receiver can decrypt the packet with several keys and check from
6813 the MAC which key decrypted the message correctly.
6815 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6816 lib/silccrypt/silccipher.[ch].
6818 * Added silc_hash_len to return the digest length into the
6819 lib/silcrypt/silchash.[ch].
6821 * Rewrote parts of Silc Channel Payload interface in the
6822 lib/silccore/silcchannel.[ch]. The encode function now also
6823 encrypts the packet and parse function decrypts it.
6825 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Fixed a minor formatting bug in the SKE's key material processing.
6828 It actually might have processed the keys wrong way resulting
6831 * Redefined the mandatory HMAC algorithms and added new algorithms.
6832 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6833 and hmac-md5 truncated to 96 bits. The mandatory is now
6834 hmac-sha1-96. Rest are optional (including the one that used
6835 to be mandatory). Rationale for this is that the truncated HMAC
6836 length is sufficient from security point of view and can actually
6837 make the attack against the HMAC harder. Also, the truncated
6838 HMAC causes less overhead to the packets. See the RFC2104 for
6841 * Added new [hmac] configuration section. The SKE used to use
6842 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6843 is of course wrong. The official names that must be proposed in
6844 the SKE are the ones defined in the protocol specification
6845 (hmac-sha1-96 for example). The user can configure any hmac
6846 using any hash function configured in the [hash] section. At
6847 least, the mandatory must be configured.
6849 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6851 * Added HMAC list to the SKE proposal list. It has now both
6852 hash algorithm list and HMAC list. This makes the protocol
6853 incompatible with previous versions. The SKE now seems to work
6854 the way it is supposed to work, for the first time actually.
6856 * Defined plain Hash algorithms to the protocol specification.
6859 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Implemented support for key agreement packets into the server.
6862 Added functions silc_server_key_agreement and
6863 silc_server_send_key_agreement. Other than these functions,
6864 server has nothing to do with this packet.
6866 * Added support for private message key packets into the server.
6867 Added functions silc_server_private_message_key and
6868 silc_server_send_private_message_key.
6872 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6873 called in the protocol's final callback instead in the END
6874 protocol state. This makes a little more sense and in the same
6875 time in client we can use the same protocol routines for normal
6876 key exchange and to key agreement packet handling as well.
6878 * Added to both client's and server's KE protocol context the
6879 SilcSKEKeyMaterial pointer to save the key material. We will
6880 bring the key material to the protocol's final callback by doing
6881 this. The final callback must free the key material.
6883 * Added SKE's packet_send callback into client's KE protocol
6884 context so that the caller can choose what packet sending function
6885 is used. This way we can use different packet sending when
6886 doing normal SKE when doing key agreement packet handling (in
6887 the key agreement packet handling we do not want to encrypt
6890 * Implemented the responder side of the key agreement routines
6891 in the client. The client can now bind to specified port and
6892 accept incoming key negotiation. The key material is passed
6893 to the application after the protocol is over.
6895 * Implemented the processing of incoming Key Agreement packet
6896 in the client. Added function silc_client_key_agreement to
6899 * Implemented the intiator side of the key agreement routines
6900 in the client. The client can now initiate key agreement with
6901 another remote client. The key material is passed to the
6902 application after the protocol is over.
6904 * Created client_keyagr.c to include all the key agreement
6907 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6908 SILC_TASK_CALLBACK except that it is not static.
6910 * Created client_notify.c and moved the Notify packet handling
6911 from the client.[ch] into that file.
6913 * Created client_prvmsg.c and moved all private message and
6914 private message key routines from the client.[ch] into that file.
6916 * Create client_channel.c and moved all channel message and
6917 channel private key routines from the client.[ch] into that file.
6919 * Changed silc_client_get_client_by_id_resolve to resolve with
6920 WHOIS command instead of IDENTIFY command, in the file
6921 lib/silclient/idlist.c.
6923 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Implemented the SKE's responder side to the Client library.
6927 * When FAILURE is received to the protocol do not trust it
6928 blindly. Register a timeout to wait whether the remote closes
6929 the connection as it should do it, only after that process the
6930 actual failure. This was changed to both client and server.
6932 * Added client_internal.h to include some of the structures
6933 there instead of client.h in lib/silcclient/.
6935 * Added function silc_task_unregister_by_callback to unregister
6936 timeouts by the callback function.
6938 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Some "Incomplete WHOIS info" errors has been appearing on the
6941 log files. Took away the entry->userinfo check from WHOIS
6942 reply sending. The entry->userinfo is now " " if client did not
6943 provide one. I thought this was fixed earlier but something
6944 is wrong still. Let's see if the error still appears.
6946 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Fixed a minor bug in the login when the channel key is
6949 re-generated in the server. It used to generate the key in
6950 wrong order and thus caused problems in the channel traffic.
6952 * Fixed a minor bug in channel key distsribution after
6953 KICK command. The key was not sent to the router even though
6956 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Added silc_ske_process_key_material_data as generic routine
6959 to process any key material as the SILC protocol dictates. The
6960 function is used by the actual SKE library but can be used by
6961 applications as well. This relates to the private message keys
6962 and the channel private keys since they must be processed the
6963 same way the normal SILC session keys. The protocol dictates
6964 this. Affected files: lib/silcske/silcske.[ch].
6966 Added also silc_ske_free_key_material to free the
6967 SilcSKEKeyMaterial structure.
6969 * Defined silc_cipher_set_key function to set the key for
6970 cipher without using the object's method function. The affected
6971 files: lib/silccrypt/silccipher.[ch].
6973 * Implemented silc silc_client_add_private_message_key,
6974 silc_client_add_private_message_key_ske,
6975 silc_client_del_private_message_key,
6976 silc_client_list_private_message_keys and
6977 silc_client_free_private_message_keys functions in the
6980 Added functions silc_client_send_private_message_key to send
6981 the Private Message Key payload and silc_client_private_message_key
6982 to handle incoming Private Message Key payload.
6984 * Added Cipher field to the Private Message Key payload to set
6985 the cipher to be used. If ignored, the default cipher defined
6986 in the SILC protocol (aes-256-cbc) is used.
6988 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Removed lib/silcclient/ops.h file.
6992 Redefined parts of the SILC Client Library API. Created new
6993 file silcapi.h that deprecates the ops.h file and defines the
6994 published Client Library API. Defined also private message key
6995 API and channel private key API into the file.
6997 This is the file that the application must include from the
6998 SILC Client Library. Other files need not be included by
6999 the application anymore.
7001 * Added new key_agreement client operation callback and also
7002 defined the Key Agreement library API for the application.
7004 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7007 is used by clients to request key negotiation between another
7008 client in the SILC network. If the negotiation is started it
7009 is performed using the SKE protocol. The result of the
7010 negotiation, the secret key material, can be used for example
7011 as private message key.
7013 Implemented the Key Agreement payload into the files
7014 lib/silccore/silauth.[ch].
7016 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Redefined ciphers for the SILC protocol. Added some new ciphers
7019 and defined the key lengths for the algorithms. Changed the
7020 code accordingly. The default key length is now 256 bits.
7022 * Fixed SKE key distribution function silc_ske_process_key_material
7023 when the key length is more than 128 bits. The default key
7024 length in SILC is now 256 bits.
7026 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7027 to indicate unsupported algorithm.
7029 * Renamed rijndael.c to aes.c and all functions as well.
7031 * Fixed a long standing channel key setting bug in client library.
7032 Weird that it has never surfaced before.
7034 * Fixed bug in channel deletion. If the entire channel is removed
7035 then it must also delete the references of the channel entry
7036 from the client's channel list as the client's channel entry and
7037 the channel's client entry share same memory.
7039 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7041 * Implemented CONNECT and SHUTDOWN commands in the client.
7043 * Implemented CLOSE command to the client.
7045 * Added the function silc_idlist_find_server_by_name into the
7046 files silcd/idlist.[ch].
7048 Added the function silc_idlist_find_server_by_conn into the
7049 files silcd/idlist.[ch].
7051 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * DIE command was renamed to SHUTDOWN. Updated the both code
7056 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7057 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7059 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7062 * Added function silc_server_create_connection function to create
7063 connection to remote router. My server implementation actually
7064 does not allow router to connect to normal server (it expects
7065 that normal server always initiates the connection to the router)
7066 so the CONNECT command is only good for connecting to another
7069 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7072 or some other client was kicked from the channel.
7074 Implemented the handling of the notify type to both client
7077 Implemented silc_server_send_notify_kicked to send the KICKED
7078 notify. It is used to send it to the server's primary router.
7080 * Implemented the KICK command into server and client.
7082 * Added `query' argument to the silc_idlist_get_client function
7083 to indicate whether to query the client from server or not if
7086 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7087 to indicate that the client is not channel founder.
7091 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Removed the rng context from SilcPacketContext structure and
7094 changed that the packet routine uses the Global RNG API.
7096 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Added support for quit message that client can "leave" on the
7099 channel when it quits the SILC. It is ditributed inside the
7100 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7102 Added silc_server_free_client_data that will take the
7103 signoff message as argument.
7105 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7107 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Updated parts of the protocol specification to keep it up
7112 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7115 payloads in one packet.
7117 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7118 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7119 use now the new List flag.
7121 * Also deprecated the following packet types: REPLACE_ID,
7122 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7124 * Added list support for Notify packet in server.
7126 * Added silc_server_send_notify_channel_change to send the
7127 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7128 the silc_server_send_replace_id.
7130 * Added silc_server_send_notify_nick_change to send the
7131 NICK_CHANGE notify type. Deprecates the function
7132 silc_server_send_replace_id.
7134 * Added silc_server_send_notify_join to send the JOIN notify type.
7135 Deprecates the function silc_server_send_new_channel_user.
7137 * Added silc_server_send_notify_leave to send LEAVE notify type.
7138 Deprecates the function silc_server_send_remove_channel_user.
7140 * Added silc_server_send_notify_cmode and
7141 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7142 types. Deprecates the silc_server_send_set_mode function.
7144 * Added SERVER_SIGNOFF notify type to indicate that server has
7145 quit. This means that all clients on the channel from that
7146 server will drop. This can be also used when netsplit happens.
7148 Deprecated REMOVE_ID packet type since it is not needed anymore
7151 Added silc_server_send_notify_server_signoff to send the
7152 SERVER_SIGNOFF notify type. Deprecates the function
7153 silc_server_send_remove_id.
7155 Added also silc_server_send_notify_signoff to send the
7156 SIGNOFF notify type.
7158 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7159 SILC protocol from this day on. Changed the protocol
7160 specification as well.
7162 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7163 notify type. It is used between routers to notify about
7164 topic changes on a channel.
7166 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7169 * Partly updated the protocol specification to comply with the
7170 changes now made. It is still though a bit outdated.
7172 * The JOIN notify type now takes one extra argument <Channel ID>.
7173 The packet used to be destined to the channel but now the
7174 JOIN type may be sent as list thus it is impossible to
7175 destine it to any specific channel. By adding this argument
7176 it is again possible.
7178 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Added CREDITS file. The CHANGES and CREDITS file will appear
7181 in the distribution as well.
7183 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7186 types in the server's silcd/packet_receive.c.
7188 * Implemented CMODE and CUMODE to work in router environment.
7190 * Fixed minor encoding and decoding buglet from the
7191 lib/silccore/silcmode.c.
7193 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7196 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7198 * Changed all SilcConfigServer* and silc_config_server* to
7199 SilcServerConfig* and silc_server_config*, respectively.
7202 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Associated the ID (client or server ID) to the Authentication
7205 Payload to avoid any possibility of forging. Updated the
7206 protocol specification and the code accordingly.
7208 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * The RSA key length is now save to the RsaKey context in the
7211 key generation process in lib/silccrypt/rsa.c. The key length
7212 is now used to figure out the maximum size of the block allowed
7213 to be encrypted/signed.
7215 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7216 is equivalent to the silc_mp_mp2bin but does not allocate any
7219 * Changed silc_mp_mp2bin API to take length argument. If it is
7220 non-zero then the buffer is allocated that large. If zero, then
7221 the size is approximated using silc_mp_sizeinbase, which however
7224 * Created Global RNG API which is global RNG that application can
7225 initialize. After initializing, any routine anywhere in the
7226 code (including library) can use RNG without allocating a new
7227 RNG object. This was done to allow this sort of use of the
7228 RNG in code that has no chance to allocate RNG object. All
7229 applications currently allocate this and many routines in the
7230 library use this. Affected file lib/silccrypt/silcrng.[ch].
7232 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7233 it to use the Global RNG API.
7235 * Defined Authentication Payload into protocol specification that
7236 is used during SILC session to authenticate entities. It is
7237 used for example by client to authenticate itself to the server
7238 to obtain server operator privileges.
7240 Implemented this payload into the lib/silccore/silcauth.[ch].
7241 Implemented also routines for public key based authentication
7242 as the new protocol specification dictates.
7244 Moved definitions of different authentication methods from
7245 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7247 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7248 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7249 silc_pkcs_verify_with_hash functions into the file
7250 lib/silccrypt/silcpkcs.[ch].
7252 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * The client entry's userinfo pointer must be always valid.
7255 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7256 will fail since it requires the userinfo. Now, the userinfo
7257 is allocated as "" if actual userinfo does not exist. Actually,
7258 it must exist and it is totally Ok to drop client connections
7259 that does not announce the userinfo. However, we will make
7260 this workaround for now.
7262 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7263 to return the remote port by socket.
7265 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7268 SILC_SERVER_PENDING_EXEC and added an new macro
7269 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7270 data or when error occurs while processing the pending command.
7272 Added new argument `destructor' into silc_server_command_pending
7273 and to the SilcServerCommandPending object. This destructor is
7274 now called after calling the pending callback or if error occurs
7275 immediately. If error occurs the actual pending callback won't
7276 be called at all - only the destructor. The destructor may be
7277 NULL if destructor is not needed.
7279 All this applies for client library code as well. Similar
7280 changes were made there as well for the pending commands.
7282 In the client, the application must now allocate the
7283 SilcClientCommandContext with the silc_client_command_alloc
7286 * Added reference counter to the SilcServerCommandContext. Added
7287 function silc_server_command_alloc and silc_server_command_dup
7290 Same type of functions added to the client library for the same
7293 * Removed the cmd_ident from IDListData away since it is now
7294 global for all connections. It is the command identifier used
7295 in command sending and with pending commands. The affected file
7298 * Added reference counter to the SilcSocketConnection objecet to
7299 indicate the usage count of the object. The object won't be
7300 freed untill the reference counter hits zero. Currently only
7301 server uses this, and client ignores it. The client must be
7302 set to use this too later. The affected files are
7303 lib/silccore/silcsockconn.[ch]. Added also the function
7304 silc_socket_dup to increase the reference counter.
7306 This was mainly added because it is possible that the socket
7307 is removed underneath of pending command or other async
7308 operation. Now it won't be free'd and proper DISCONNECTING
7309 flags, etc. can be set to avoid sending data to connection that
7310 is not valid anymore.
7312 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7313 the connection. After that it sets SILC_SET_DISCONNECTED.
7314 It is, however, possible that the socket data is not still freed.
7315 The silc_server_packet_process now checks that data is not
7316 read or written to connection that is DISCONNECTED. The socket
7317 get's freed when the reference counter hits zero.
7319 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Changed the client operation API: channel_message operation's
7322 `sender' is now the client entry of the sender, not the nickname
7323 and the `channel' is the channel entry, not the channel name.
7325 In the private_message operation the `sender' is now also the
7326 client entry of the sender not the nickname.
7328 Affected file is lib/silcclient/ops.h and all applications
7329 using the client operations.
7331 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Moved the calling of ops->connect() from connect_to_server_final
7334 into receive_new_id functin since that is the point when the
7335 client is actually allowed to send traffic to network. The
7336 affected file is lib/silcclient/client.c.
7338 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7340 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7341 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7342 (if needs broadcasting) instead of broadcasting the packets one
7343 by one which would make a burst in the network traffic.
7345 * Added `broadcast' argument to the functions in silcd/server.[ch]
7346 silc_server_create_new_channel[_with_id] to indicate whether
7347 to send New Channel packet to primary router.
7349 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Added new function into the silcd/server.[ch] files:
7352 silc_server_create_new_channel_with_id to create new channel with
7353 already existing Channel ID.
7355 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7356 lib/silccore/silcpacket.h. This packet is used t send list of
7357 Set Mode payloads inside one packet. Server uses this to set
7358 the modes for the channels and clients on those channels, that it
7359 announced to the router when it connected to it. The protocol
7360 specification has been updated accordingly.
7362 * The silc_server_new_channel did not handle the packet coming
7363 from normal server as it normally does not send that. However,
7364 when it announces its channels it does send it. Implemented
7365 the support for that.
7367 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7368 into the file lib/silccore/id.h.
7370 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Fixed memory leaks in the functions silc_idlist_del_client,
7373 silc_idlist_del_channel and silc_idlist_del_server in the file
7374 silcd/idlist.c. All of those leaked like a sieve.
7376 * Fixed some small memory leaks in the client's function
7377 silc_client_notify_by_server.
7379 * Added functions into silcd/server.c: silc_server_announce_clients,
7380 silc_server_announce_channels and silc_server_announce_server.
7381 These functions are used by normal and router server to announce
7382 to its primary router about clients, channels and servers (when
7383 router) that we own. This is done after we've connected to the
7386 These functions effectively implements the following packet types:
7387 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7388 and SILC_PACKET_NEW_ID_LIST.
7390 * Added new functions into the silcd/packet_receive.[ch]:
7391 silc_server_new_id_list, silc_server_new_channel_list and
7392 silc_server_new_channel_user_list to handle the incoming
7393 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7395 * Added support of changing Channel ID in the function
7396 silc_server_replace_id. If the server that announces a channel
7397 to the router already exists in the router (with same name but
7398 with different Channel ID), router is responsible to send
7399 Replace ID packet to the server and force the server to change
7400 the Channel ID to the one router has.
7402 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7403 client that the Channel ID has been changed by the router. The
7404 normal server sends this to the client. Client must start using
7405 the new Channel ID as the channel's ID.
7407 Implemented handling of this new type into lib/silcclient/client.c
7408 into the function silc_client_notify_by_server.
7410 * Added new function silc_idlist_replace_channel_id into the files
7411 silcd/idlist.[ch] to replace the Channel ID.
7413 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Call silc_server_command_identify_check always when processing
7416 the IDENTIFY command in silcd/command.c
7418 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7421 send keepalive packets. The packet can be sent by clients,
7422 servers and routers.
7424 Added function silc_socket_set_heartbeat into the file
7425 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7426 If not set, the heartbeat is not performed. The actual
7427 heartbeat is implemented in the low level socket connection
7428 library. However, application is responsible of actually
7431 Added silc_server_send_heartbeat to send the actual heartbeat
7432 packet into silcd/packet_send.[ch]. Server now performs
7433 keepalive with all connections.
7435 * Added silc_task_get_first function into lib/silcutil/silctask.c
7436 to return the timeout task with shortest timeout. There was a bug
7437 in task unregistration that caused problems. TODO has been
7438 updated to include that task system must be rewritten.
7440 * The client library will now resolve the client information when
7441 receiving JOIN notify from server for client that we know but
7442 have incomplete information.
7444 * Rewrote parts of silc_server_remove_from_channels and
7445 silc_server_remove_from_one_channel as they did not remove the
7446 channel in some circumstances even though they should've.
7448 * Encryption problem encountered in server:
7450 The LEAVE command used to send the Channel Key packet to the
7451 router immediately after generating it. However, the code
7452 had earlier sent Remove Channel user packet but not immediately,
7453 ie. it was put to queue. The order of packets in the router
7454 was that Channel Key packet was first and Remove Channel User
7455 packet was second, even though they were encrypted in the
7456 reverse order. For this reason, MAC check failed. Now, this
7457 is fixed by not sending the Channel Key packet immediately but
7458 putting it to queue. However, this is more fundamental problem:
7459 packets that are in queue should actually not be encrypted
7460 because packets that are sent immediately gets encrypted
7461 actually with wrong IV (and thus MAC check fails). So, packets
7462 that are in queue should be encrypted when they are sent to
7463 the wire and not when they put to the queue.
7465 However, the problem is that the current system has not been
7466 designed to work that way. Instead, the packet is encrypted
7467 as soon as possible and left to the queue. The queue is then
7468 just purged into wire. There won't be any fixes for this
7469 any time soon. So, the current semantic for packet sending
7472 o If you send packet to remote host and do not force the send
7473 (the packet will be in queue) then all subsequent packets to the
7474 same remote host must also be put to the queue. Only after the
7475 queue has been purged is it safe again to force the packet
7478 o If you send all packets immediately then it safe to send
7479 any of subsequent packets through the queue, however, after
7480 the first packet is put to queue then any subsequent packets
7481 must also be put to the queue.
7483 Follow these rules and everything works fine.
7485 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Added new function silc_server_remove_clients_by_server to
7488 remove all client entries from ID list when the server connection
7489 is lost. In this case it is also important to invalidate all
7490 client entires as they hold the invalid server entry. This
7491 fixes fatal bug when server has lost connection and will reconnect
7494 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7496 * Made some sanity checks to silc_server_daemonise like to check
7497 whether the requested user and group actually exists.
7499 * Added sanity check to SKE's silc_ske_responder_finish to check
7500 that the public and private key actually is valid.
7502 * Invalidate the client's nickname when receiving Replace ID
7503 packet and the Client ID is being replaced. This means that the
7504 server will query the nickname if someone needs it (client)
7507 * Sort the ID Cache in client library when the ID Cache data
7508 has changed (needs sorting).
7510 * Do not allow for SILC client to create several connections to
7511 several servers. The client does not support windows right now
7512 and generating multiple connections causes weird behaviour.
7514 Irssi-silc client does support windows and can handle several
7515 connections without problems, see: www.irssi.org and SILC plugin.
7517 * Fixed some places where client was added to the IDList. The
7518 rule of thumb is following (in order to get everything right):
7519 If the client is directly connected local client then the
7520 `connection' argument must be set and `router' argument must be
7521 NULL to silc_idlist_add_client function. If the client is not
7522 directly connected client then the `router' argument must
7523 bet set and the `connection' argument must be NULL to the
7524 silc_idlist_add_client function.
7526 * The funtion silc_server_packet_send_local_channel actually did
7527 not check whether the client was locally connected or not. It
7528 does that now. Fixed a bug related to LEAVE command.
7530 * Fixed Remove Channel User payload parsing bug in server's
7531 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7533 * The server's silc_server_save_channel_key now checks also the
7534 global ID list for the channel as it might not be in the local
7535 list. Fixed a bug related to LEAVE command.
7537 * Is this the end of the [<unknown>] buglet that has been lurking
7538 around for a long time? A little for loop fix in server's
7539 silc_server_command_whois_parse that is used by both IDENTIFY
7540 and WHOIS command. At least, this was a clear bug and a cause
7541 of one type of [<unknown>] buglet.
7543 * WHOIS and IDENTIFY commands call the function
7544 silc_server_command_[whois/identify]_check function even if
7545 we are not router server.
7547 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Added --with-gmp configuration option. If set the GMP
7550 is always compiled in the SILC source tree. If not set then
7551 it is checked whether the system has the GMP3 installed. If
7552 it has then the GMP won't be compiled (the system's headers
7553 and library is used), if it doesn't have it then the GMP is
7554 compiled in the SILC source tree.
7556 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Changed RSA private exponent generation to what PKCS #1
7559 suggests. We try to find the smallest possible d by doing
7560 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7561 not security fix but optimization.
7563 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * Added new config entry [Identity] to fork the server and run
7566 it as specific user and group. A patch from Bostik.
7568 * Imported Dotconf configuration library into lib/dotconf.
7569 This will be used to create the SILC configuration files later.
7570 It will appear in the distsribution after this commit.
7572 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * A big code auditing weekend happening. Auditing code for
7575 obvious mistakes, bugs and errors. Also, removing any code
7578 Removed files for being obsolete:
7580 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7581 inline in the file lib/silcutil/silcbuffer.h)
7583 o lib/silcutil/silcbufutil.c (the header has inline versions)
7585 Changed code to fix possible error conditions:
7587 o The buffer formatting routines now check that the destination
7588 buffer really has enough space to add the data. This applies for
7589 both buffer formatting and unformatting
7590 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7591 unformatting was changed to accomodate following rules:
7592 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7593 sent to the function while XXX_*STRING will not allocate or copy
7594 the data into the buffer. Instead it sets the pointer from the
7595 buffer into the pointer sent as argument (XXX_*STRING used to
7596 require that the pointer must be allocated already). This change
7597 makes this whole thing a bit more consistent and more optimized
7598 (note that the data returned in the unformatting with XXX_*STRING
7599 must not be freed now). The routines return now -1 on error.
7601 o Tried to find all code that use buffer_format and buffer_unformat
7602 and added return value checking to prevent formatting and
7603 especially unformatting errors and possible subsequent fatal
7606 o Changed ske->x and ske->KEY to mallocated pointers in
7607 lib/silcske/silcske.h. Fixed possible data and memory leak.
7609 o Added return value checking to all *_parse* functions. Fixed
7610 many memory leaks as well.
7612 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7613 so that buffer overflows would not happen. All code now also
7614 checks the return value as it can fail.
7616 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Added reconnection support to server if the normal server looses
7619 its connection to the router (for example if router is rebooted).
7620 The server performs normal reconnection strategy implemented
7621 to the server. Affected file silcd/server.c.
7623 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Added new packet type SILC_PACKET_SET_MODE that is used to
7626 distribute the information about changed modes (for clients,
7627 channels and clients channel modes) to all routers in the
7628 network. Updated the protocol specification accordingly.
7630 Added functions into silcd/packet_send.c and
7631 silcd/packet_receive.c: silc_server_send_set_mode,
7632 silc_server_set_mode.
7634 Added new files silcmode.[ch] into lib/silccore that implements
7635 the encoding and decoding of Set Mode Payload. Added new type
7636 SilcSetModePayload. Moved the definitions of different modes
7637 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7639 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Oops, a little mistake in server's connection authentication
7642 protocol. The protocol is not ended with FAILURE but with
7643 SUCCESS if the authentication is Ok. :) Affected file is
7646 * Implemented NICK_CHANGE notify handling in server in the file
7647 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7648 the local clients on the channel. After the changing nickname
7649 in router environment snhould work and the [<unknown>] nickname
7650 should appear no more.
7652 The silc_server_replace_id function that receives the Replace ID
7653 payload now sends the NICK_CHANGE notify type also in the file
7654 silcd/packet_receive.c
7656 * Changed WHOIS and IDENTIFY command to support the maximum amount
7657 of arguments defined in protocol specs (3328 arguments). This
7658 fixed a bug that caused problems when there were more than three
7661 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Added extra parameter, command identifier, to the
7664 silc_client_send_command so that explicit command identifier
7667 Changed that ID list routines uses specific command identifier
7668 when sending WHOIS/IDENTIFY requests to the server so that they
7669 can be identified when the reply comes back.
7671 Affected files lib/silcclient/command.[ch],
7672 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7674 * Added `sender' argument to silc_server_packet_send_to_channel
7675 to indicaet the sender who originally sent the packet to us
7676 that we are now re-sending. Ignored if NULL. Affected file
7677 silcd/packet_send.[ch].
7679 * Added some server statistics support in silcd/server_internal.h
7680 SilcServerStatistics structure and around the server code. Also
7681 send some nice statistics information when client is connecting
7684 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Fixed channel ID decoding in server's JOIN command reply in
7687 silcd/command_reply.c
7689 * Fixed braodcasting of replace ID payload to not to send it if
7690 we are standalone server in silcd/packet_receive.c.
7692 * Fixed all channel message sending routines to not to send
7693 packets to clients that has router set, since they are routed
7694 separately in the same function earlier. Affects file
7695 silcd/packet_send.c and all channel packet sending functions.
7697 * In USERS reply, res_argv[i] are not allocated, the table
7698 is allocated. Thus changed that free the table, not its
7701 * In server's whois_check and identify_check if the client is
7702 locally connected do not send any WHOIS commands - they are not
7705 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Fixed some minor bugs in client when sending WHOIS command. The
7708 arguments was in wrong order.
7710 * Removed statis function add_to_channel from server in
7711 silcd/command.c that was previously used with the joining but
7714 * Tested USERS command in router environment successfully with two
7715 routers, two servers and two clients.
7717 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Reorganized the USERS command and command reply in client library
7720 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7721 When the command is given by user we register a pending command
7722 callback that will reprocess the command after the reply has been
7723 received from the server. When reprocessing the packet we then
7724 display the information. Thus, the USERS information is displayed
7725 now in the command callback instead of in the command reply
7726 callback. The processing of the command is same as previously
7727 when server has sent the command reply in the JOINing process.
7729 * Added to USERS command in silcd/command_reply.c to join the client,
7730 we didn't use to know about, to the channel after we've created
7731 a client entry for it. Also, for clienet we did know already still
7732 check whether it is on the channel or not and add it if not.
7734 * Removed silc_server_command_join_notify as the function and its
7737 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Changed the client's pending command handling to the same as the
7740 server's pending command handling. It is also now possible to
7741 execute command reply functions from other command reply
7742 function as the function callbacks for commands and command
7743 replies are one and same. The pending commands are not static
7744 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7745 in client connection context. Thus, pending commands are server
7746 connection specific as it is convenient.
7748 Changed the function silc_client_command_pending and
7749 silc_client_command_pending_del and added new function
7750 silc_client_command_pending_check. Removed the
7751 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7754 * Added cmd_ident, current command identifier, to the client
7755 connection context in lib/silcclient/client.h to keep track on
7756 command identifiers used in command sending. Client's command reply
7757 function handling now supports the mandatory command identifiers.
7759 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7760 funtions in client to fully support pending command callbacks.
7762 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7763 as one of the arguments to the application in the command reply
7766 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7767 before first releasing SILC but came back. Now it is removed again
7768 and should come back nomore. The FORWARDED flag was used only
7769 by the JOINing procedure by forwarding the command packet to router.
7770 Now, the JOINing procedure has been changed to more generic (due
7771 to various router environment issues) and FORWARDED is not needed
7772 anymore for anything. The protocol specification is yet to be
7775 Now, removed silc_server_packet_forward from server and the flag
7776 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7778 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7780 * Renamed NAMES command to USERS command. The NAMES was named that
7781 due to historical reasons. Now it is renamed. Also, rewrote
7782 parts of the USERS command. The nickname list is not sent anymore
7783 by the server. Only Client ID and mode lists are sent in the USERS
7784 command. Changed this also to the protocol specification.
7786 The client now resolves the names and stuff after it receives
7787 the USERS list from the server when joining to the channel.
7789 * WHOIS and IDENTIFY commands has been changed to support multiple
7790 Client ID's per command. One can now search for multiple users
7791 in the network by sending only one WHOIS or IDENTIFY command.
7792 Changed the code and the protocol specifications.
7794 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7795 uses silc_server_command_whois_parse to parse the request. */
7797 * If normal server, do not parse the WHOIS and IDENTIFY requests
7798 before sending it to the router. Saves some time.
7800 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7802 * Fixed JOIN command on client library. Wrong number of arguments
7803 used to crash the client.
7805 * Added silc_server_channel_has_global function to check whether
7806 channel has global users or not.
7808 * Added silc_server_channel_has_local function to check whether channel
7809 has locally connected clients on the channel.
7811 * The silc_server_remove_from_one_channel now checks whether the
7812 channel has global users or not after given client was removed from
7813 the channel. It also checks whether the channel has local clients
7814 on the channel anymore. If it does not have then the channel entry
7815 is removed as it is not needed anymore.
7817 * The silc_server_notify now checks on JOIN notify whether the joining
7818 client is one of locally connected or global. If it is global then
7819 the channel has now global users on the channel and that is marked
7820 to the channel entry. Also, it now saves the global client to
7821 global list who is joining and JOINs it to the channel. This is
7822 for normal server, that is.
7824 Changed silc_server_send_notify_on_channel,
7825 silc_server_packet_relay_to_channel and
7826 silc_server_packet_send_to_channel check if we are normal server
7827 and client has router set (ie. global client) do not send the
7828 message to that client, as it is already routed to our router.
7830 * Implemented LEAVE notify type handling in silc_server_notify
7833 * Tested LEAVE command in router environment successfully. Tested
7834 with two routers, two servers and two clients.
7838 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7840 * Implemented SIGNOFF notify type handling in silc_server_notify
7843 * silc_server_remove_id now removes the client entry from all channels
7844 it has joined and thusly sends SIGNOFF notify type.
7846 * Rewrote the NAMES list generation in server by removing two excess
7847 loops. The lists are created now inside one loop.
7849 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * silc_server_remove_channel_user checks now also global list
7852 for channel and client.
7854 * silc_server_new_channel_user checks now both local and global
7855 list for channel and client. Fixed a bug in client id decoding.
7856 Used to decode wrong buffer.
7858 * silc_server_channel_message checks now both local and global
7859 list for channel entry.
7861 * Tested channel joining (hence JOIN) in router environment
7862 successfully. Tested with two routers, two servers and two
7865 * Tested channel message sending in router environment successfully.
7867 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Added silc_server_save_channel_key into server.[ch] to save the
7870 received channel key in Channel Key payload processing. It is
7871 also used in JOIN command reply handling.
7873 Equivalent function silc_client_save_channel_key added into
7874 client.[ch] into client library.
7876 * Changed JOIN command reply to send information whether the channel
7877 was created or not (is existing already) and the channel key
7878 payload. Changed protocol specs accordingly.
7880 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7881 the request was sent by ID and not by nickname. Crashed on
7884 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7886 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7887 now correctly save the received data.
7889 * silc_server_free_sock_user_data now notifies routers in the
7890 network about entities leaving the network.
7892 At the same time implemented functions silc_server_remove_id
7893 and silc_server_send_remove_id to receive and send REMOVE_ID
7894 packets. The packet is used to notify routers in the network
7895 about leaving entities. The ID removed will become invalid in
7898 * Added function silc_idlist_del_server into server. Removes and
7899 free's server entry from ID list.
7901 * silc_server_private_message function now checks, if we are router,
7902 that the destination ID really is valid ID, naturally.
7904 * In router when NEW_ID packet is received (for new client) the
7905 hash of the Client ID is saved in the ID Cache but the
7906 client->nickname is set to NULL, instead of putting the hash
7909 IDENTIFY command now also checks that client->nickname must be
7910 valid. If it is not if will request the data from the server who
7911 owns the client. Added new function
7912 silc_server_command_identify_check.
7914 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7915 to set the command to already allocated Command Payload.
7917 * Tested private message sending in router environment with two
7918 routers, two servers and two clients. Fixed minor bugs and now
7921 * Fixed segfault from client's NAMES command. Used to crash if
7924 * Forwarded packets must not be routed even if it is not destined
7925 to the receiver. Changed server code comply with this.
7927 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Added `require_reverse_mapping' boolean value to ServerParams
7930 structure. If TRUE (not default) the server will require that
7931 the connecting host has fully qualified domain name.
7933 If the reverse mapping is not required and hostname could not be
7934 found the IP address is used as hostname.
7936 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Implemented version string checking to both client and server.
7939 The check is incomplete currently due to the abnormal version
7940 strings used in development version of SILC.
7942 * Changed all command functions in server to use the new
7945 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7947 * Changed char *data to unsigned char *data in ID Cache system to
7948 support binary data as ID Cache data. Changed code to support
7949 binary data in lib/silccore/idcache.c.
7951 * Renamed silc_server_packet_relay_command_reply to
7952 silc_server_command_reply as it is normal packet receiving
7953 function. Rewrote the function to accept command replys for
7954 servers and not only for clients.
7956 * Mark remote router always as registered server if we are connecting
7957 to it. Otherwise, commands sent by the router to us are ignored.
7959 * All ID List find routines now returns the ID Cache Entry pointer
7960 as well if requested.
7962 * WHOIS command works now in router environment, tested with two
7963 routers, two servers and two clients.
7965 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7966 in router environment (as it is almost equivalent to WHOIS) but
7967 hasn't been tested thoroughly. Added new functions:
7969 silc_server_command_identify_parse
7970 silc_server_command_identify_send_reply
7971 silc_server_command_identify_from_client
7972 silc_server_command_identify_from_server
7974 * Disabled route cache adding because adding two different ID's with
7975 same IP replaces the old cache entry thus giving wrong route.
7976 The entry->router->connection is always the fastest route anyway
7977 so route cache may not be needed. Of course, new routes maybe
7978 established after receiving the ID when the entry->router->connection
7979 might not be anymore the most optimal.
7981 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * Add route cache for received ID for fast routing.
7985 * Added silc_server_packet_route to route received packet on router
7986 that is not destined to us.
7988 * Renamed silc_server_get_route to silc_server_route_get.
7990 * Added id_string and id_string_len fields into SilcServer to
7991 include encoded ServerID for fast comparing without excess
7992 encoding of the ID's.
7994 * Cleaned up WHOIS command on server side. Added following static
7997 silc_server_command_whois_parse
7998 silc_server_command_whois_check
7999 silc_server_command_whois_send_reply
8000 silc_server_command_whois_from_client
8001 silc_server_command_whois_from_server
8003 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8004 arguments in command replies. All command functions should be
8005 updated to use this macro.
8007 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8009 * Minor typo fixes on command reply handling on server.
8011 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Added silc_server_command_add_to_channel internal routine to add
8014 the client to the channel after router has created the channel and
8015 sent command reply to the server.
8017 * Added generic silc_server_send_command to send any command from
8020 * Use static buffer with ID rendering instead of duplicating data.
8022 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8024 * Fixed a channel user mode bug when joining to a channel server gave
8025 everybody channel founder rights, oops.
8027 * We mark ourselves as the router of the incoming server connection
8028 if we are router ourselves. This way we can check in some packet
8029 sending functions whether it is locally connected server. For
8030 incoming router connections we put NULL.
8032 * For router sending packets locally means now always sending the
8033 packet cell wide; to local clients and local servers. For normal
8034 server sending packet locally means sending it to only local
8037 * Fixed the JOIN command to really work in router environment. If the
8038 channel is created it is always created by the router. Router is
8039 also responsible of making the initial joining to the channel,
8040 sending JOIN notify to the sending server and distributing
8041 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8042 does not exist server doesn't do anything else but forward the
8043 command to the router which performs everything.
8045 * Added silc_server_send_channel_key function to send the Channel Key
8048 * Added silc_server_create_channel_key to create new channel key. The
8049 channel key is now re-generated everytime someone joins or leaves
8050 a channel, as protocol dictates. Note: channel->key_len is the
8053 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8056 packet_receive.[ch] to separate packet sending and receiving
8057 routines. The server.[ch] now includes everything else including
8058 actual packet processing (writing and reading data) and other
8061 Renamed silc_server_private_message_send_internal to
8062 silc_server_send_private_message. The routine is still though
8063 used only to relay private messages as server does not send
8064 private messages itself.
8066 Renamed silc_server_new_channel to silc_server_create_new_channel
8067 and added new function sicl_server_new_channel that handles the
8068 incoming New Channel packet. Added also new sending function
8069 silc_server_send_new_channel to send New Channel Payload.
8071 * Added new function silc_server_notify to process incoming notify
8072 packet to the server/router. Server may then relay the notify
8073 to clients if needed.
8075 * Added new function silc_server_new_channel_user to process incoming
8076 New Channel User packet. Router will redistribute the packet and
8077 send JOIN notify to its local clients and locally connected servers
8078 if needed. Normal server will send JOIN notify to its local client
8079 on same channel when received this packet. Added also corresponding
8080 sending function silc_server_send_new_channel_user to sent the
8083 * Added boolean route argument to send_notif_to_channel and
8084 packet_send_to_channel functions to attempt to route the packet
8085 if it is TRUE and send only locally if it is FALSE.
8087 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * silc_server_replace_id now broadcasts the received replace ID
8090 packet if it is not broadcast packet already. The router must
8091 broadcast to inform other routers about changed ID.
8093 * Added backpointer to server's router into SilcServer context in
8094 silcd/server_internal.h.
8096 * Fixed silc_server_packet_broadcast to send correct broadcast
8099 * The channel key is now distributed to the local client as soon
8100 as it is received from the router (in router environment) so that
8101 no other packet may be sent for the channel until client has
8104 * silc_server_remove_channel_user now broadcasts the received
8105 Remove Channel User packet if it is not broadcast packet already.
8106 The router must broadcast to inform other routers about removed
8109 * Added users field into SilcPacketContext that is a reference count
8110 of the context. One can increase the reference count by calling
8111 silc_packet_context_dup which is now changed to just increase the
8112 reference count instead of duplicating the data. The reference
8113 count is decresed by calling silc_packet_context_free that will
8114 free the data after the reference count hits zero.
8116 For now on the packet context and everything allocated into it
8117 (including the raw packet from network) must be freed by calling
8118 the new silc_packet_context_free function. Added also new function
8119 silc_packet_context_alloc that must be used now to allocate the
8120 context. This also means that if a routine is asynchronous from
8121 silc_[client/server]_packet_parse_type the packet context must
8122 be duplicated by calling silc_packet_context_dup. Otherwise it
8123 gets free'd after silc_[client/server]_packet_parse_type returns.
8124 Also, one must remember that if packet is duplicated then its
8125 reference count must be decresed by calling the free function as
8126 many times as it was duplicated.
8128 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8129 from both client and server.
8131 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Made joining to a channel working in router environment.
8135 * Cleaned up JOIN command on server side and create function
8136 silc_server_command_join_channel internal routine to make the
8139 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8141 * Changed silc_command_pending list to SilcDList. Also, added
8142 `ident' field to SilcServerCommandPending structure to identify
8143 the reply and to call correct callback.
8145 Added silc_server_command_pending_check function to replace the
8146 corresnponding macro. The silc_command_pending list is not
8149 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8150 to set identifier to previously allocated Command Payload. It
8151 is used to set identifier for command when resending Command
8154 * Added silc_command_payload_encode_payload to encode Command
8155 Payload buffer from SilcCommandPayload structure.
8157 * Added silc_argument_payload_encode_payload to encode Argument
8158 payload buffer from SilcArgumentPayload structure.
8160 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Changed WHOIS command to support router connection on server side.
8163 The whois request is always sent to router unless the server is
8164 standalone server. After server has received the reply from the
8165 router will it send the reply to the client.
8167 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8168 broadcast received broadcast packet. The function is used only
8169 by router. The broadcast packet is always sent to the router's
8172 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8173 render given ID to printable string, for log files for example.
8175 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8177 * Made basic router to router connections working. At least they
8178 can now connect to each other but nothing really works the way
8179 they are supposed - yet.
8181 * Added new initiator token to RouterConnection configuration
8182 file in silcd/serverconfig.[ch]. It is used to tell whether we
8183 are the initiator to the remote router or whether we'll expect
8184 the other end to connect.
8186 * Moved registering of listener task to silc_server_init, hence
8187 the server starts listenning as soon as it is run, even if it
8188 does not have connections to other routers. Let's see how well
8191 * Changed default connection retry timeouts for more suitable in
8194 * Removed cipher and such arguments from silc_idlist_add_client
8195 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8196 Added new function silc_idlist_add_data to add the keys and stuff
8199 * Added SilcIDListData structure and added it to SilcClientEntry
8200 and SilcServerEntry as their first field in the structure. This
8201 way we can explicitly cast the ID entries to the SilcIDListData
8202 structure and get common data for the entries. In past, we had
8203 to first check what type of connection it is and then cast it to
8204 correct ID entry type. Now, we can directly cast the opaque
8205 pointer to the SilcIDListData (no matter what ID entry it actually
8206 is) and get the data needed.
8208 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8211 in some circumstances even if threre were timeout tasks, though not
8212 IO tasks, but tasks anyway. Now fixed.
8214 * Defined SilcServerConnection structure to hold connection specific
8215 stuff about directly connected servers and routers. The definition
8216 is currently in silcd/server_internal.h. I thought about having
8217 a bit more important role fro this struct but for now it is used
8218 only when connecting to other server (or router actually).
8220 * Added connecting retry support in server when connecting to
8221 router(s). The retry feature implement exponential backoff
8222 algorithm. Also, added SilcServerParams structure to hold default
8223 parameters for server. For now, it include these retry settings
8224 and are hard coded. After server is moded to be as Silc Server
8225 Library this structure will be more important.
8227 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8229 * Changed client librarys channel->clients table to SilcList and
8230 changed code accordingly.
8232 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Changed client's channel table to SilcList and changed code
8235 accordingly. Also changed SilcChannelClientEntry to include back-
8236 pointer to the channel so that client entry can use that structure
8237 as list as well and we have fast cross-reference to the channel.
8238 This change dramatically decreased the complexity of channel
8239 handling with client entry and vice versa (removed one extra
8240 loop when searching for channel entry from many functions).
8242 * Changed server->sim from table to SilcDList and changed code
8245 * NAMES command can now be used from user interface. It will show
8246 the user list on the channel, neatly.
8248 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8249 Code now saves realname of the user if it becomes available.
8251 * Renamed configure.in to configure.in.pre and made ./prepare
8252 script to automatically add correct version string to
8253 configure.in which it creates from configure.in.pre.
8255 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8257 * NAMES command reply now shows users mode with the nickname when
8260 * Moved silc_client_ch[u]mode[_char] functions from
8261 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8262 place sucks, they are utility functions and should be in some
8265 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8267 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8270 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Added TRQ (efficient deque and list library) into lib/trq. This is
8275 a very good list library that is currently used in the SILC. Defined
8276 SilcList API over the library because I didn't like the API very
8277 much. See lib/trq/silclist.h for the API and examples of how to
8278 use the API. Fixed various places in the code to use the new
8279 SilcList API. The SilcList is meant for lists that has a structure
8280 already defined as a list. It is not suitable to add just some
8281 context to the list (in TRQ, the context is the list actually).
8283 So, I defined SilcDList that can be used for the purpose where
8284 predefined list structure does not exit. This can be used as
8285 such list. Now some context just can be added to the SilcDList.
8286 Currently this list is not used in the SILC just yet, though there
8287 are a lot places where this can replace dynamically allocated
8288 tables and I will fix these places, later, to use SilcDList.
8289 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8290 and use TRQ internally).
8292 Also fixed some annoying warning messages that the original TRQ
8293 code generated. Also minor changes to TRQ's Makefile.in.
8295 * Added support for querying by Client ID to both WHOIS and
8296 IDENTIFY commands into server, as required by the protocol.
8298 * Removed method function pointers from SilcBuffer structure. They
8299 weren't used to anything and just increased the context size for
8300 no good reason. This change also made silc_buffer_alloc and
8301 silc_buffer_free functions inline functions.
8303 * Disabled command flooding detection support until it's fixed so
8304 that it accepts commands in but does not execute them more than once
8307 * Added silc_net_localhost(), to return local hostname, into
8308 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8309 that must be initialized before calling silc_client_init.
8311 * Added new function: silc_server_send_notify_on_channels to send
8312 notify messages to all channels client has joined. It is assured
8313 that the message is sent only once per client.
8315 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8316 lib/silcutil/silcutil.[ch] as silc_format function. The new
8317 function is generic and is used by server as well, not only by
8318 the logging routines.
8320 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8321 the provided version string was not acceptable. Added new function:
8322 silc_ske_check_version into lib/silcske/silcske.h. The function
8323 must be implemented by the application (client or server) and it
8324 does not reside in the SKE library. The function checks the version
8325 string remote end sent.
8327 * Added back pointers (to opaque context and to SilcSocketConnection)
8328 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8330 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8331 duplicate packet context structure.
8333 * Changed `notify' client operation to send same arguments as client
8334 receives from server except for ID's. ID's are mapped to correct
8335 ID entry and that is returned. Also, if channel entry is not sent
8336 by server but the notify is for channel the channel entry is sent
8337 to application (otherwise application doesn't know that it is for
8338 channel (library gets it from packet's Destination ID)).
8340 * Added silc_client_remove_from_channels into client library to
8341 remove a client from all channels it has joined to. Used when
8342 received SIGNOFF notify from server. Added also new function
8343 silc_client_replace_from_channels to replace old ID entry with
8344 new ID entry on all channels. Used when received NICK_CHANGE
8347 * Fixed ID Cache list handling in silc_idlist_get_client in
8348 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8349 to get (or query) client by ID.
8351 * Updated TODO list.
8353 * Added connection authentication status message defined by the
8354 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8355 support for these into the code in client and server side.
8357 * Added generic function silc_client_send_command to send any command
8358 with variable argument list. Application should use this function
8359 to send commands if the command functions provided by the library
8360 does not suite for the application's user interface needs.
8362 * Added new `failure' client operation. Application is notified about
8363 received failure packet if client is executing a protocol. In this
8364 case the protocol's execution has failed.
8366 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8367 is required by the protocol.
8369 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8370 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8373 * Added status flag to SilcSKE object to indicate realtime status
8374 of the SKE protocol.
8376 * Application receives now exactly same command reply arguments as
8377 the library receives from server. However, if ID is received the
8378 corresponding ID entry is returned to the application (eg. Client
8379 ID is mapped to correct SilcClientEntry entry and that is returned).
8380 Changed command_reply client operation due to this change.
8382 * Changed all ID's in commands and in command replys as ID Payloads.
8383 Change affected both client and server side codes.
8385 All ID's sent in SILC network (with execption of ID's in SILC
8386 Packet header) are sent in ID Payload to support variable length
8389 * Server now notifies nick changes and notifies all clients on
8390 the channels about the new nickname (about the new Client ID,
8393 * Implemented CMODE command to change channel modes. Supports all
8394 channel modes defined by the protocol specs except ban and invite
8395 lists. (Also, private channel key mode is supported but support for
8396 setting private channel key in client is missing, thus, this mode
8397 has no effect on client side (except that server requires that the
8398 client uses private channel key and normal channel traffic does not
8401 Also, invite mode works per se, but INVITE command does not work
8402 yet correctly, so you can set channel as invite only channel but
8403 inviting clients to the channel does not work (it is yet to be
8404 thought what's the best way to do it).
8406 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8407 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8408 Implemented CUMODE command to change user's mode on the channel.
8409 Supports all modes defined by the protocol specs.
8411 * Added NAMES command reply to return users modes on the channel.
8413 * Removed unnecessary and slow ciphers from lib/silccrypt.
8415 * Set SO_KEEPALIVE option to connection sockets by default.
8417 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8419 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8420 redefined the Notify Payload into protocol specs.
8422 * Added silc_id_payload_parse_id to get ID directly from raw
8425 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8427 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8428 accept searching by Client ID as well.
8430 * Added support for LEAVE and SIGNOFF notify types in client library.
8432 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8433 to parse ID Payload from raw data.
8435 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Added flags parameter into silc_ske_assemble_security_properties
8438 function in lib/silcske/silcske.[ch].
8440 * Changed notify client operation to fit better for notify messages
8441 sent by server. The notify payload received from server is now
8442 passed to the application (after parsing it to SilcNotifyPayload).
8443 It is application's responsibility to retrieve the arguments
8444 from the payload and show the message the way it wants. The message
8445 sent by server is implementation specific.
8447 * Changed public keys to comply with the protocol specification.
8448 Old public keys are not supported anymore and are not compatible.
8450 * Removed nickname from Channel Payload as the latest draft removed
8451 it. The client must resolve the nickname from the NAMES command
8452 reply received when it joined the channel.
8454 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8456 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8458 * Fixed some errors in protocol specification drafts.
8460 * Created lib/silccore/silcnotify.c to implement Notify Payload
8461 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8462 generic payloads described by protocol specifications. The file
8463 includes implementations for ID Payload and Argument Payload.
8465 * Changed Command Payload implementation to use the new Argument
8466 Payload. Changed command_xxxx_payload to command_payload_xxxx
8467 to comply with SILC coding conventions.
8469 * Added suppport for Argument Payload handling in Notify Payload
8470 implementation as protocol requires it. Added the new support
8471 into server and client lib as well.
8473 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8475 * Added support for multiple nicknames on same channel. [n] is
8476 added locally to the nickname if there are more than one same
8477 nicknames on the channel.
8479 * Server now sends all nicknames that matched WHOIS request.
8480 Client also shows the list received from server.
8482 * Added TOPIC command to client side. User can now set and show
8483 current topic on channel.
8485 * Added MOTD command to client and server. Also, server sends the
8486 motd when client connects to the server.
8488 * Changed version strings to comply ISO 8601.
8490 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8492 * Fixed protocol error handling in client library. It should now
8493 cope even if the SKE fails for some reason.
8495 * Made new protocol specification drafts for submitting to IETF.
8497 * Implemented TOPIC command to server in silcd/command.c.
8499 * Added two new notify types into lib/silccore/silcnotify.h:
8500 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8501 notify nickname change and topic setting/change on a channel.
8503 * API change of command_reply operation in client library. The
8504 application gets now the status type received from server as well.
8506 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8508 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8510 * Cras fixed and optimized the packet handling even further and
8511 it should work now. Minor change to the prototype of function
8512 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8514 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8516 * Added new function into lib/silcutil/silcschedule.[ch]:
8517 silc_schedule_with_fd to select() a specified fd. The function
8518 returns after timeout expires or data arrives or goes. The
8519 function is used by packet routines to wait that all data is
8520 received from network.
8522 * Fixed data reading from network in lib/silccore/silcpacket.c.
8523 The code now assures that all data is read from the fd and then
8524 continues packet processing. This was a bug fix since the code
8525 used to drop some data in some circumstances.
8527 * Added new function into lib/silcclient/client.[ch]:
8528 silc_client_start_key_exchange to start key exchange after
8529 connection has been established to server. The code internally
8530 now uses this funtion but its main purpose was to provide it
8531 for applications that perform their own connecting. After
8532 application has created a connection it merely calls this
8533 function to start the key exchange between client and server.
8534 The library takes care of everything else after that.
8536 Updated also lib/silcclient/README to explain the usage of
8539 * Do not send to application information that connection has
8540 been established. Application gets notified it by connect
8543 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8545 * Applied cras's patch to add silc_schedule_one function. The
8546 function runs scheduler once and returns.
8548 * Fixed the scheduler after cras messed it up. The timeout
8549 handling works now as it's supposed to work.
8551 * Added into lib/silccore/ silcnotify.h to include notify
8552 message types support. Changed silc_server_send_notify*
8553 functions, in server.[ch], to support those new notify types.
8554 Added the support for the notify types into client library,
8555 as well. Added new notify client operation into ops.h in
8558 * Changed silc_server_packet_send_to_channel to send normal
8559 packets instead of just channel message packets. The function
8560 is now used to send the notify packets to channels. It is not
8561 used to send channel message packets anymore, as server never
8564 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8565 va_arg()s as it seems to require it nowadays. I guess, if SILC
8566 is compiled with older va_arg() the new code should work anyway.
8568 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8570 * Splitted core library. Core library (lib/silccore) includes
8571 now only SILC protocol specific core (and common) components.
8572 Created new utility library (lib/silcutil) that includes more
8573 generic purpose stuff. The stuff for util library was taken
8574 from the old core library. This was minor and easy split.
8576 * Created SILC Client Library (lib/silcclient) that includes
8577 implementation of the SILC client without user interface. This
8578 was major move from silc/ directory. The code has been changed
8579 so that it is transparent towards the user interface. The
8580 silc/ directory includes now the same user interface as before
8581 and it uses the new client library. Read lib/silcclient/README.
8582 Basicly, the client library performs everything else related
8583 to SILC except user interface handling. Also, configuration
8584 files are considered to be part of user interface and library
8585 does not handle them.
8587 This change also changed a lot of structures, function naming etc.
8588 Most important change was that SilcClientWindow object was
8589 renamed to SilcClientConnection in the client library. Created
8590 also new file lib/silcclient/ops.h. Also added new files
8591 silc/local_command.[ch] and silc/client_ops.[ch].
8593 All these changes were made to make it easier for user interface
8594 designers to create what ever user interface for the SILC client
8597 It is also expected that the server will be moved to lib
8598 directory as well and SILC Server Library will be created;
8599 sometimes in the future.
8601 * Removed Local commands from lib/silccore/silccommand.h as
8602 they are application specific and new client library does not
8603 handle any of those anymore.
8605 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8606 old client implementation in silc/.
8608 * Added support for callback functions in SILC_LOG_* macros.
8609 Application can now set its own callbacks that will be called
8610 instead of using the default functions that will always print
8611 the debug messages to stderr (or stdout). Also, debugging can
8612 now be disabled by setting silc_debug to FALSE and re-enabled by
8613 setting it to TRUE. Note, that logging will still work even
8614 if debugging is disabled.
8616 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8617 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8618 silc_log_reset_debug_callbacks.
8620 * To enable debugging in silc client one must give now -d
8621 option on command line.
8623 * Changed silc_schedule_init to automatically allocate task queues
8624 if they are not allocated before calling it.
8626 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8628 * Added GMP 3.1 into math library.
8630 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8632 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8633 a channel in SILC network. The packet is used by servers and
8634 routers to notify other routers that user has left a channel.
8635 This little feature was missing until now. Added the feature
8636 to protocol specification as well.
8638 Added functions: silc_server_send_remove_channel_user and
8639 silc_server_remove_channel_user into server.[ch].
8641 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8642 lib/silccore/silcpacket.h. However, they are not implemented
8645 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8647 * Fixed joining to a channel and sending channel messages
8648 between server and router. The channel message sending should
8649 now work inside a cell.
8651 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8653 * Fixed the private message sending between server and router.
8654 The private message sending should now work inside a cell.
8656 * Added silc_server_replace_id into server.[ch] to replace
8657 existing ID in the SILC network.
8659 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8660 and silc_idlist_replace_server_id into idlist.[ch] in server.
8662 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8664 * Fixed the server to server connections. Server can again now
8665 connect to router. Router to router connections probably does
8668 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8670 * Added dynamic protocol registering support. Now protocols can
8671 registered and unregistered on the fly. Patch by cras.
8673 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Added lib/contrib directory to hold routines that some platforms
8676 don't have but are needed by SILC.
8678 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8679 into lin/contrib to provide getopt() and getopt_long() for
8680 those who don't have it.
8682 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8684 * Added AWAY command to client. When away message is set and
8685 client receives a private message packet the client automatically
8686 replies to the sender with the away message.
8688 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8689 bug seemed to be the cause of recent problems when compiling
8692 * Added version detection support to SKE protocol specification
8693 and added the new changes to the SKE implementation as well.
8694 There were other minor changes in the SKE protocol as well.
8696 Many changes in lib/silcske/silcske.[ch] and in
8697 lib/silcske/payload.[ch].
8699 * Added ^U functionality, clear input line. Patch from cras.
8701 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8703 * Mainly small bugfixes on core library. Fixed some debugging
8704 logging and buffer overflow in silclog.c.
8706 * Updated config.sub and config.guess on the distribution tree.
8708 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8710 * Added command lagging support in server. Client may execute
8711 commands now only once in two seconds.
8713 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8715 * Optimized packet reception. MAC computation and checking is now
8716 also more optimized. A lot previously duplicated code is now
8717 used as generic by both client and server.
8719 * Fixed key pair generation in clientutil.c
8721 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8723 * Added into lib/silccore/silcbufutil.[ch] new function;
8724 silc_buffer_realloc.
8726 * Moved generic packet sending/encryption functions to
8727 lib/silccore/silcpacket.[ch] from client and server. Some
8728 rewriting of the functions.
8730 * Moved all generic packet reception/decryption functions to
8731 lib/silccore/silcpacket.[ch] from client and server. The
8732 packet processing is now much cleaner in both client and server.
8733 These were major changes in both client and server.
8735 * Created many common functions in server to do packet sending.
8736 Previously code were duplicated a lot, this has been removed
8739 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8741 * Rewrote major parts of the ID cache system. Don't know
8742 whether it is better now or not but at least the API is more
8745 * Major rewrite on ID cache stuff on client because of the ID
8746 cache API changes. Added idlist.c to client.
8748 * Also major rewrite on ID cache stuff on server as well.
8749 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8750 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8751 in hand, instead they are all put into the ID cache system now.
8752 All server_idlist_* routines uses ID cache now instead of
8753 traversing its own lists (those lists does not exist anymore).
8754 SilcIDList though still exists. Also, SilcXXXEntry's are
8757 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8759 * Finally made the SKE implementation compliant to the protocol
8760 specification. All mp integers are now binary encoded as
8761 opposed being HEX encoded.
8763 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8766 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8767 functions: silc_[encode/decode]_pem. Also added function
8768 silc_encode_pem_file to PEM encode with newlines ('\n') for
8771 * SILC public keys are now encoded either PEM or binary. Same
8772 option is for private keys as well. By default private keys
8773 are binary encoded and public keys PEM encoded. Silly HEX
8774 encoding were removed.
8776 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8777 function to create fingerprints.
8779 * Fixed a bug in SHA1; does not change the original data anymore.
8781 * Partly implemented INFO command on client and server side.
8782 Fixed CLEAR command. Changes to SERVER command; show current
8783 server(s) when giving command without arguments. Added
8784 VERSION command to client.
8786 * Added check to server that unregistered connections cannot
8787 execute commands (unless it is specificly allowed).
8789 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8791 * Fixed screen refresh.
8793 * Fixed channel joining bug from client. On some circumstances
8794 client tried to join to a channel it had already joined.
8796 * Added public key verification process into client's protocol.c.
8797 The client now verifies the public key from user and saves
8798 it into ~./silc/serverkeys/ directory.
8800 Added into: clientutil.[ch]: silc_client_verify_server_key.
8802 * Changed SKE protocol's silc_ske_initiator_finish function
8803 to accept callback function that verifies the received public
8804 key. Removed old silc_ske_verify_public_key function.
8806 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8808 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8809 silc_pkcs_private_key[_data]_set.
8811 * Made the password and public authentication more cleaner in
8812 server's protocol.c.
8814 * Removed historic and obsolete protocol `channel_auth' from
8815 both client and server.
8817 * Removed wrong way of sending command status messages from
8818 server to client in server's command.c. The old way violated
8819 protocol specification.
8821 Changes to silccore/silccommand.[ch]: removed
8822 silc_command_encode_status_payload -> not needed anymore,
8823 changed silc_command_encode_payload_va to accept extra
8824 argument on variable argument list. The argument type must
8825 now be provided to the function. Also, added new function:
8826 silc_command_encode_reply_payload_va which is same as
8827 normal command_encode_payload_va except command status type
8828 is provided as extra argument.
8830 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8832 * Added ~./silc directory handling. The directory includes the
8833 public and private keys for the client.
8835 Added silc_client_check_silc_dir, silc_client_create_identifier
8836 and silc_client_load_keys.
8838 * Implemented SILC protocol compliant public key. Added public
8839 and private key saving to and loading from files.
8841 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8842 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8843 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8844 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8845 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8847 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8848 silc_pkcs_load_[public/private]_key.
8850 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8852 * Added silc_server_get_route (route.[ch]) to get connection
8853 data for the fastest route for given ID.
8855 * Implemented INVITE command on client and server. The command
8856 were re-defined in the SILC Protocol Specification and the
8857 implementation now complies with the specification.
8859 * Implemented PING command on client and server.
8861 * Implemented NAMES command on client and server. The server side
8862 supports currently only normal server not router server yet.
8863 Some changes to NAMES definition in SILC protocol specification.
8865 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8867 * Implemented LEAVE command on client and server.
8869 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8870 again. This change was made to the protocol as well. Server
8871 should not violate the protocol specification anymore.
8873 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8875 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8876 was tested. SOCKS4 was not but should work anyway.
