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

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

50 backup router does not have connection to primary router yet.
52 Affected file is silcd/server.c.
54 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Added silc_client_udpate_server function to update changed
57 server info. Affected file lib/silcclient/idlist.[ch].
59 * Added check for server entries that are being resolved when
60 notify is received. If being resolved, handle the received
61 notify only after it's resolved so that all notifys are
62 handled in same order as received from the server.
64 Added similar resolver check to channel entries. Every
65 notify that cause resolving of any information that affects
66 channel entry marks the channel entry in waiting state.
67 After whatever resolving is over the waiters are signalled
68 and only then the notifys are handled in the same order
69 as delivered from the server.
71 Affected files are lib/silcclient/idlist.[ch], and
74 * Fixed KILLED notify handling in normal server. Affected
75 file silcd/packet_receive.c.
77 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
78 is locally connected, or was locally connected (but may

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

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

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

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

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

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

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

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

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

766 mask to the client. Updated protocol specs and the server.
767 Affected file is silcd/command.c.
769 * Changed the Killer's Client ID in KILLED notify to be just
770 any ID payload since router server is allowed to kill as well.
771 Updated protocol specs, client libary and server. Affected
772 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
773 and irssi/src/silc/core/client_ops.c.

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

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

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

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

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

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

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

978 Affected file silcd/protocol.c.
980 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
982 * Some client implementations quit network by doing first LEAVE
983 and then immediately SIGNOFF (like Bombyx). We now do check
984 after a short time after LEAVE notify and check whether the
985 client is still valid after LEAVE, and if not we remove it from
986 cache. Affected file is lib/silcclient/client_notify.c.
988 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
990 * Merged version 1.1.4 of zlib. Even if it not currently in use,

1003 totally saved 16 bytes of memory per context after optimization.
1004 Affected files are lib/silccore/silcpacket.[ch].
1006 * Made strict checks for valid SILC IDs. Affected file is
1007 lib/silccore/silcid.c.
1009 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1012 silc_hash_register, silc_hmac_register and silc_pkcs_register
1013 to const. Affected files are lib/silccrypt/silccipher.[ch],
1014 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1016 * Changed the silc_get_username and silc_get_real_name to
1017 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1019 * Fixed the Irssi SILC Client to use the silc_get_username and
1020 silc_get_real_name insted of glib routines since the glib
1021 routines only corrupt stack. Fixes the Irssi SILC to work in
1022 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1024 * Fixed the Irssi to not use g_get_home_dir since it crashes
1025 or returns garbage on cygwin and corrupts stack. Added function
1026 get_home_dir to Irssi routines. Affected files are
1027 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

1031 * Made some structure optimizations. SFTP memory FS MemFSEntry
1032 entry structure. Optimized SilcTask structure. Optimized
1033 SilcPacketContext structure.
1035 Affected files lib/silcsftp/sftp_fs_memory.c,
1036 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1038 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1040 * And yet again reverted back the config thing since Johnny

1044 * Fixed memory leaks from config object. Affected files are
1045 silcd/serverconfig.[ch].
1047 * Added support for adding new connections to the server in rehash.
1048 After rehash they take effect.
1050 Added support for changing the maximum allowed connections in
1051 rehash. The number can grow but going smaller is not supported.

1062 Affected files are silcd/serverconfig.[ch], server.c.
1064 * Moved functions silc_server_drop() and silc_server_daemonise()
1065 from server.c to silcd.c since they are stricly related to
1066 the application activity.
1068 * Reverted a small part of the automatic ref/unref since
1069 it caused a double unref in some situations. Affected
1070 files are silcd/silcd.[ch], server.c, serverconfig.c.
1072 * Added some .cvsignore files in the lib directory.
1074 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1076 * Fixed silc_net_gethostbyaddr to correctly resolve by
1077 address. Affected file lib/silcutil/silcnet.c.
1079 * Fixed the notify relaying to client. The HMAC to be used
1080 with relayed packets ws wrong and caused decryption failure
1081 at the client end. Affected file is silcd/packet_receive.c.
1083 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1085 * Created new branch silc_protocol_1_0_branch.
1087 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1089 * Changed the silc_server_config_* routines to be SilcServer
1090 independent. They are now officially application specific code
1091 and not part of generic server implementation. Affected files
1092 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1094 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1096 * Added automatic referencing of config context in the
1097 silc_server_config_alloc, and automatic unreferencing in the
1098 silc_server_config_destroy. Affected files are
1099 silcd/serverconfig.[ch], silcd/silcd.c.
1101 * Fixed the silc_log_quick handling in the logging routines.
1102 It didn't log quickly when it was TRUE. Affected file is
1103 lib/silcutil/silclog.c. Also the flush delay was set even
1104 if it was 0 in config file. Affected file is
1105 silcd/serverconfig.c.
1107 * Added support for changing key pair of the server in rehash.
1108 Affected file silcd/server.c.
1110 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1113 too early, before getting the channel entry. Affected file
1114 is silcd/packet_receive.c.
1116 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1118 * Added functions silc_server_config_[ref/unref], these are used
1119 to prevent that the config object is destroyed.
1121 No longer directly affect global variables silc_log_quick and
1122 silc_log_delay, they are first cached inside the config object
1123 and then applied with silc_server_config_setlogfiles().
1125 silc_server_config_set_defaults() is now internal to
1126 serverconfig.c, there are no reasons to show this internal stuff
1129 Affected files are silcd/serverconfig.[ch].
1131 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1132 fprintf's to stderr, since some code may be executed again after
1133 the server went into the background. Affected files are
1136 * Added rehash support. Added function silc_server_rehash() that
1137 will perform all the basic tasks of the rehashing procedure.
1139 * Added command line option `-x, --hexdump'. This will enable the
1140 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1141 The option `--hexdump' implies `--debug'.
1143 * Fixed a bad bug in the logging APIs (silcutil library) where
1144 the application would crash after calling silc_log_reset_all().
1146 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1148 * Fixed the KICKED notify handling in client library to
1149 correctly remove the channel and all entries from the
1150 channel when I was kicked. This bug crashed the client.
1152 Fixed yet another but in KICKED notify handling to remove
1153 the kicked client correctly from the channel.
1155 Affected file is lib/silcclient/client_notify.c.
1157 * Fixed a minor bug in looking up correct client entry
1158 in KICKED notify in server. Affected file is
1159 silcd/packet_receive.c.
1161 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1162 sources correctly to distribution. Fixes --with-gmp option.
1164 * Removed the manual rehashing from ID Cache, and changed it
1165 to use the SILC Hash Table's auto rehash feature. Affected
1166 file is lib/silccore/silcidcache.c.
1168 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1170 * Fixed a bug in the silc_client_nickname_format function that
1171 handles the multiple same nickname formatting. Two clients
1172 with same nickname caused problems after the first one left
1173 and rejoined. It didn't format the nickname correctly.
1174 Affected file is lib/silcclient/idlist.c.
1176 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1178 * Don't change the topic if olod topic is same as new one.
1179 Affected file is silcd/packet_receive.c.
1181 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1183 * Added cross-reference support to the SILC Documentation
1184 generator. All types across all HTML files are now cross-
1185 referenced. Affected files util/robodoc/generator.c and
1186 scripts/silcdoc/silcdoc.
1188 * Added file lib/silcutil/silctypes.h to include all the
1189 arithmetic type definitions and some macros. Removed
1190 includes/bitmove.h and moved macros to silctypes.h.
1192 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1194 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1196 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Added `type' argument to silc_id_payload_parse_id function which
1199 now returns the type of the ID to the sent pointer. Affected
1200 file is lib/silccore/silcid.[ch].
1202 * Added check for CMODE_CHANGE notify type that mode change is
1203 allowed by the sender. Affected file silcd/packet_receive.c.
1205 * Added check for CUMODE_CHANGE notify type that mode change is
1206 allowed by the sender. Affected file silcd/packet_receive.c.
1207 Added the ID type as CUMODE_CHANGE notify type as argument
1208 to the `notify' client operation. Affected files are
1209 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1211 * Added function silc_client_add_server to the client library.
1212 Added support for resolving also channel and server info when
1213 received unknown entity in notify packet. Affected files are
1214 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1216 * Added function silc_command_get_status to return the command
1217 status from the command reply's argument payload. Affected files
1218 are lib/silccore/silccommand.[ch].
1220 * Added check for KICKED notify type that the kicking is
1221 allowed by the client. Affected file silcd/packet_receive.c.
1223 * Created function silc_get_input which can be used to get input
1224 (echo on or off) from user on command line. Affected files are
1225 lib/silcutil/silcutil.[ch].
1227 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1229 * Optimized silc_server_packet_relay_to_channel function.
1230 Added new function silc_channel_message_payload_encrypt which
1231 can be called directly if channel message payload needs to
1232 be encrypted and is already encoded (no need to call _encode
1233 function). Packet relaying is now done by router without any
1234 extra memory allocations. Affected files are
1235 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1236 silcd/packet_send.c.
1238 * Fixed the INVITE notify handling. It took wrong arguments
1239 as invite list and invite delete. Affected file is
1240 silcd/packet_receive.c.
1242 * Added check for TOPIC_SET notify type that the topic change is
1243 allowed by the client. Affected file silcd/packet_receive.c.
1245 * Added check for INVITE notify type that inviting is allowed by
1246 the client. Affected file silcd/packet_receive.c.
1248 * Changed the silc_server_client_on_channel to return the
1249 SilcChannelClientEntry as well. Moved the function
1250 silc_server_check_cmode_rights to server_util.[ch].
1251 Affected files are silcd/server_util.[ch], silcd/command.c.
1253 * Added function silc_server_check_umode_rights to check whether
1254 changing client's user mode is allowed. Added check for
1255 UMODE_CHANGE notify type that the umode change is allowed
1256 by the client. Affected files are silcd/server_util.[ch],
1257 silcd/packet_receive.c and silcd/command.c.
1259 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1262 ID length. It ignored that ID can be IPv6 based as well.
1263 Affected file lib/silccore/silcpacket.h.
1265 * Fixed the silc_id_id2str and silc_id_str2id to take the
1266 IPv6 address offset's into consideration. Affecte file is
1267 lib/silccore/silcid.c.
1269 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * Fixed the internal Unix scheduler functions to check for
1272 NULL context they may receive. The affected file is
1273 lib/silcutil/unix/silcunixschedule.c.
1275 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1277 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1278 can specify different directory with --home command line
1279 parameter. Affected files irssi/src/silc/core/client_ops.c,
1282 * SILC-specific commands aren't now executed if the active server
1283 isn't of SILC-type, so there won't be problems with having
1284 IRC and SILC protocol support in same client. Affected files
1285 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1288 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1290 * Improved the signal support in SILC Schedule. Added new
1291 function silc_schedule_signal_call which is used by application
1292 to mark a signal to be called. It is now safe to perform
1293 any kind of tasks in signal callbacks since it is guaranteed
1294 that the application specified signal callback is called
1295 after the signal is over. Affected files are
1296 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1298 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1300 * Added `name' field to SilcChannelPrivateKey to represent
1301 application given name for the key. Moved also the context from
1302 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1303 Added the `name' argument also to the function
1304 silc_client_add_channel_private_key.
1306 Added function silc_client_current_channel_private_key to set the
1307 current channel private key in use.
1309 Added "change" command to KEY command which can be used to change
1310 the current channel private key. Bound the command also to
1311 alt+K (Alt+Shift+k).
1313 Also affected files lib/silcclient/client_channel.c,
1314 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1316 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1318 * Added silc_rng_get_byte_fast function in to the
1319 lib/silccrypt/silcrng.[ch].
1321 * Changed the interface of silc_packet_assemble and the
1322 silc_packet_send_prepare. If silc_packet_assmble is now
1323 called the application does not call silc_packet_send_prepare
1324 because the library will call it automatically. These
1325 interfaces now also return a reference to the outgoing buffer
1326 which includes the assembled packet, which the application can
1327 use to encrypt the packet.
1329 Affected files are lib/silccore/silcpacket.[ch],
1330 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1331 silcd/packet_send.c, server_backup.c and packet_receive.c.
1333 * Fixed a packet sending bug on very high load, where outgoing
1334 packet queue wasn't handled correctly and packets got corrupted.
1335 Affected files are lib/silcutil/*/silc*sockconn.c,
1336 lib/silcclient/client.c and silcd/server.c.
1338 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Added macro SILC_PACKET_DATALEN which can be used during
1341 packet assembling to check whether the data to be added to
1342 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1343 len is truncated until it fits it.
1345 Added checks for maximum length of channel message payload and
1346 private message payload also.
1348 Added checks for maximum packet length in server and in
1351 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1352 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1353 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1354 lib/silcclient/client_prvmsg.c.
1356 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Added silc_server_packet_queue_purge call to the
1359 silc_server_disconnect_remote to assure that all data in the
1360 queue before disconnecting is sent to the network. Affected
1361 file silcd/server.c.
1363 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1365 * Added the deleting of server's own ID cache entry to the
1366 silc_server_free function. Free also everything else that
1367 has been allocated in silc_server_init. The affected file
1370 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1372 * Added functions silc_parse_version_string, silc_version_to_num,
1373 and silc_ske_parse_version to parse SILC protocol style version
1374 strings. Affected files lib/silcutil/silcutil.[ch] and
1375 lib/silcske/silcske.[ch].
1377 * Added new configuration params: version_protocol, version_software
1378 and version_software_vendor to specify what version the remote
1379 host must at least be to be able to connect to server. The vendor
1380 string can be regex matched too. Added new function
1381 silc_server_connection_allowed to check maximum number of allowed
1382 connections, and allowed versions for incoming connections.
1383 Affected files are silcd/server.c, server_util.[ch] and
1386 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1388 * Added preliminary support for signals in scheduler. The
1389 signals we care about are now blocked always when the scheduler
1390 is locked. This way we can synchronise the use of signal with
1391 scheduler. It is guaranteed that when signal occurs the scheduler
1392 is not locked, and thus new tasks can be safely added to the
1395 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1396 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1397 Added new platform specific routines
1398 silc_schedule_internal_signals_[un]block and
1399 silc_schedule_internal_signal_[un]register.
1401 Added new functions to SILC Schedule API:
1402 silc_schedule_signal_[un]register. Each signal that application
1403 is going to use should be registered to the scheduler.
1405 Affected files are lib/silcutil/silcschedule.[ch],
1406 lib/silcutil/*/silc*schedule.c.
1408 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Check for unauthenticated client and server in the
1411 silc_server_new_client and silc_server_new_server functions.
1412 Affected file silcd/packet_receive.c.
1414 * Added function silc_string_is_ascii to check whether given
1415 string is 7-bit ASCII string. Affected files are
1416 lib/silcutil/silcutil.[ch].
1418 * Added function silc_id_is_valid_server_id into the
1419 silcd/serverid.c and added checking for valid Server ID's in
1420 silc_server_new_server. The Server ID must always be based
1421 on the server's public IP address.
1423 * Added logging of DISCONNECT packet message in the server.
1424 Affected file silcd/server.c.
1426 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Changed all library interfaces that use Global RNG to also
1429 accept SilcRng as argument. Affected files are
1430 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1431 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1432 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1433 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1434 lib/silccrypt/rsa.c.
1436 * Added function silc_pkcs_generate_key to the
1437 lib/silccrypt/silcpkcs.[ch] for applications so that they
1438 don't need to do pkcs->pkcs->init calls anymore.
1440 * Remove SilcSocketConnection from the SFTP API since it really
1441 wasn't needed there. The application has the information
1442 saved in its contexts anyway and the SFTP layer doesn't need
1443 know about it. Affected files lib/silcsft/silcsftp.h and
1444 lib/silcsftp/sftp_[server/client].c.
1446 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1447 The SilcSimContext is not SilcSim.
1449 * Fixed possible buffer overflows in silc_id_render in the
1450 lib/silcutil/silcutil.c.
1452 * On EPOC the global crypto module lists are not used at all
1453 in the crypto library. Added support for using the constant
1454 algorithm list on EPOC. Affected files are
1455 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1458 * Fixed the handling of third parameter of KICKED notify, since
1459 it was mistakenly updated to SILC Protocol 1.0 even though it
1460 is to be included in 1.1. Since it is not in 1.0 it is not
1461 mandatory, and this fix now handles it only if it is provided,
1462 and it is not error if it is not provided. Affected file
1463 lib/silcclient/client_notify.c.
1465 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1467 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1468 client. Affected file irssi/src/silc/core/client_ops.c.
1470 * Merged with Irssi 0.8.4 from irssi.org CVS.
1472 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1474 * Check for valid socket connection in client entries before
1475 sending any messages. Fixes a crash, but doesn't fix some
1476 other underlaying bug that is lurking there. Affected
1477 file silcd/packet_send.c.
1479 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1481 * $usermode, $cumode and $cumode_space expandos shouldn't do
1482 anything with non-SILC server records. Affected file
1483 irssi/src/silc/core/silc-expandos.c
1485 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1487 * Fixed the silc_net_check_[host/local]_by_sock to support
1488 IPv6 bound sockets as well. Now they can return IPv6 addresses
1489 as well. Affected file lib/silcutil/silcnet.c.
1491 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1492 Affected lib/silcutil/unix/silcunixnet.c.
1494 * Fixed ID rendering (at least on some platforms, not NetBSD)
1495 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1497 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1499 * Added silc_hash_public_key and silc_hash_public_key_compare
1500 functions to be used with SilcHashTable. They can be used to
1501 hash public keys and compare public keys in hash table. Affected
1502 file lib/silcutil/silcutil.[ch].
1504 * Added support for specifying multiple public keys for Client
1505 connection section in server configuration file. This makes it
1506 possible to accept multiple public keys from same host, or to
1507 make a section that accepts any incoming host, and have the
1508 accepted public keys listed in the section.
1510 Added functions silc_sever_[find/get]_public_key, added the
1511 support for this actually to all connection sections but only
1512 the Client section is currently allowed to specify multiple
1515 Affected files are silcd/server.c, server_internal.h,
1516 command.c, protocol.c, server_util.[ch], packet_receive.c.
1518 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1520 * Merged Irssi 0.8.2 from irssi.org CVS.
1522 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1524 * If silc_debug is TRUE, also output standard logging messages
1525 to stderr with the debug output.
1527 Made silc_log_reset_all() flushing all channels before returning.
1528 Also fixed some documentation typos.
1530 Affected files are lib/silcutil/silclog.[ch].
1532 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * Fixed the server to check correctly the amount of connections
1535 from single host, by checking also the type of the connection.
1536 Fixed also the comparison of number of connections and number
1537 of allowed connections. Affected files are silcd/server.c,
1540 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1542 * Fixed the USERS command reply to save the user's mode on the
1543 channel as well. Fixed JOIN command reply to check whether a
1544 client is on channel already and not join it twice. Affected
1545 file lib/silcclient/command_reply.c.
1547 * Added new file silc-expandos.c into irssi/silc/core/ to return
1548 various stuff for various signal for the statusbar etc. updating.
1549 Now Irssi SILC client prints channel user modes etc. on the
1552 * The user mode (like server/router operator changes) is now shown
1553 on the Irssi SILC client's statusbar. The affected files are
1554 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1556 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1558 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1559 to SILC_SCHEDULE_[UN]LOCK macros.

1619 application does not need to define them. Affected file
1620 includes/silcincludes.h.
1622 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1623 old name went against naming convention. Applications now
1624 include "silcclient.h" instead of "clientlibincludes.h".
1625 Removed includes/clientlibincludes.h, it is redundant now.
1627 * Renamed includes/version.h to silcversion.h.
1629 * Added really preliminary support for OS/2 into the util

1687 the SKE interface a bit.
1689 * Fixed padding problem in PKCS#1. The padding was not actually
1690 random since the random number generator was used incorrectly.
1691 This security bug affects only when encrypting with PKCS#1, and
1692 it is not currently used at all in SILC. SILC only use signing
1693 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1778 the connection configuration object from the SilcServerConnection
1779 object instead of finding it during the connecting phase.
1780 Added the configuration object to SilcServerConnection struct.
1781 Affected files silcd/server_internal.h, server.c.
1783 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1809 public key is set. If not set, public key is preferred.
1810 This has effect only when being initiator (responder will try
1813 Added support for authentication with passphrase and public key
1814 at the same time. The passphrase is tried first always since
1815 it is faster to check.
1817 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1819 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1866 zero port also if the hostname is NULL because it could not
1869 Call file transfer monitor callback now also if error occurs
1870 during key agreement protocol.
1872 Changed the silc_client_file_send interface to return the
1873 SilcClientFileError instead of session id. The session ID
1874 is returned into pointer provided as argument.

1946 * Fixed a bug in hash table tarversing. While the hash table
1947 is traversed with SilcHashTableList the table must not be
1948 rehashed. It is now guaranteed that auto rehashable tables
1949 are not rehashed while tarversing the list. Also defined that
1950 silc_hash_table_rehash must not be called while tarversing
1951 the table. Added function silc_hash_table_list_reset that must
1952 be called after the tarversing is over. The affected files are
1953 lib/silcutil/silchashtable.[ch].
1955 * Changed all hash table traversing to call the new
1956 silc_hash_table_list_reset in server and in client library.
1958 * Added function silc_client_on_channel to return the
1959 SilcChannelUser entry if the specified client entry is joined

1974 * When sending JOIN command to router for processing the
1975 sender's old command identifier was not saved back to the
1976 sender's command context, fixed now. The affected file is
1979 * Create the key in JOIN command of the router did not return
1980 the channel key, added check for this. Affected file is
1983 * Fixed a channel ID update bug in JOIN command reply. Do
1984 not directly upgrade the ID but call the function
1985 silc_idlist_replace_channel_id if the ID was changed.
1986 Affected file silcd/command_reply.c.
1988 * Fixed memory leaks from command calling if it would fail.

2088 * Removed the SilcClientCommandDestructor from the client
2089 libary, it is not needed anymore. Affected files are
2090 lib/silcclient/silcapi.h, command[_reply].[ch],
2091 client_notify, idlist.c.
2093 * Fixed GETKEY command to first resolve client, and then
2094 resolve the server only if the client was not found, instead
2095 of resolving both at the same time. Affected file is
2096 lib/silcclient/command.c.
2098 * Added silc_client_start_key_exchange_cb and lookup the
2099 remote hostname and IP address before starting the key
2100 exchange with server. The affected file is
2101 lib/silcclient/client.c.
2103 * The server's public key is now saved using the IP address
2104 of the server and not the servername for the filename.
2105 The hostname public key filename is checked as an fall back
2106 method if the IP address based filename is not found.
2108 Fixed the GETKEY command to save the fetched server key
2109 in correct filename.
2111 Print the remote server's hostname now when new key is
2112 received during connection process. Affected file is
2113 irssi/src/silc/core/client_ops.c.
2115 * Return always our own public key to the client if it asks
2116 for it with GETKEY command. Affected file silcd/command.c.
2118 * Removed the use_auto_addr variable from default config
2119 file since it was in wrong section. Affected file is
2122 * Fixed TOPIC_CHANGE notification to not route it when it
2123 was sent using silc_server_send_notify_to_channel function.
2124 Affected file silcd/command.c.
2126 * Fixed silc_server_send_notify_kicked to send the kicker's
2127 Client ID also, it was missing. Affected files are
2128 silcd/command.c, silcd/packet_send.[ch].
2130 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2132 * Do not save client history information in SERVER_SIGNOFF.
2133 Fixes the bug in normal server that it does not detect
2134 the client becoming valid after the server becomes back
2135 online. Affected file silcd/server_util.c.
2137 * Added `sock_error' field into the SilcSocketConnection
2138 context. When error occurs during socket operation (read
2139 or write) the error is saved. Added also new function
2140 silc_socket_get_error to return human readable socket error
2141 message. Affected files are lib/silcutil/silcsockconn.[ch],
2142 lib/silcutil/unix/silcunixsockconn.c, and
2143 lib/silcutil/win32/silcwin32sockconn.c.
2145 * The server now prints the socket error message in the
2146 signoff for client. Affected file silcd/server.c.
2148 * Fixed the `created' channel information sending from router
2149 to server in JOIN command. Checks now whether the channel
2150 really was created or not and set it according that.
2152 Fixed the JOIN command to use the client entry's current
2153 ID during the joining procedure instead of the one it sent
2154 in the command (it is checked though), since it can change
2155 between the packet processing and command processing, and
2156 would just case unnecessary pain in the client end. Affected
2157 file silcd/command.c.
2159 * Fixed a channel key payload sending to use correct channel
2160 ID when the server was forced to change the channel's ID by
2161 router. Router sent the key payload with the old Channel ID.
2162 Affected file silcd/packet_receive.c.
2164 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2166 * Call silc_server_save_channel_key only if the key payload
2167 was provided in the JOIN command's command reply. Affected
2168 file silcd/command_reply.c.
2170 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2172 * Fixed silc_mp_sizeinbase to return the value correctly with
2173 MPI. Affected file lib/silcmath/mp_mpi.c.
2175 * Fixed the stop_server signal to correctly stop the scheduler
2176 and gracefully stop the server when SIGTERM or SIGINT signals
2177 are received. Affected file silcd/silcd.c.
2179 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2181 * Simple handling of TERM and HUP signals. Also added some log
2182 flushing call around. Affected file is
2185 * Fixed small bugs in silclog.c. Now buffering output will take
2186 effect after 10 seconds since startup: This will ensure that
2187 no important startup messages are lost. Also output redirection
2188 will preserve original format ([Date] [Type] message).
2189 Affected file is lib/silcutil/silclog.c.
2191 * Added two options to the config file, in the logging section:
2192 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2193 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2195 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2197 * Do not print the warning about log files not being initialized
2198 more than once to avoid excess logging. Affected file is
2199 lib/silcutil/silclog.c.
2201 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2202 the SIM copying in make install in Makefile.am.pre.
2204 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2206 * Rewritten silclog APIs. Globally interesting changes follows:
2207 silc_log_set_files() changed to silc_log_set_file().
2208 silc_log_set_callbacks() changed to silc_log_set_callback().
2209 ROBOdoc documented silclog header file.
2210 SilcLogCb now returns bool to wether inihibit the default
2211 handler or not (to keep the old behaviour return always TRUE).
2212 The new APIs should also fix the problem of the
2213 silcd_error.log file that was written in the current directory.
2216 Log files streams will remain opened after silc_log_set_file()
2217 call, means less CPU usage notably on high traffic servers.
2218 File streams are now full buffered, and flushed to the disk
2219 every 5 minutes, lesses HD activity and CPU usage.
2220 Messages can be redirected, allowing admins to configure
2221 one single logfile for all server messages.
2222 the silc_log_quick global variable to activate fast-logging.
2223 Affected files lib/silcutil/silclog.[ch]
2225 * Changed some code to conform new silclog APIs. Affected
2226 files are doc/example_silcd.conf.in, silcd/server.c
2227 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2230 * Fixed a memory leak that could occur in some situations.
2231 Affected file silcd/serverconfig.c.
2233 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2235 * Added the silc_client_del_client to remove the client from
2236 all channels as well. Affected file lib/silcclient/idlist.c.
2238 * Fixed the client library to correctly remove the client
2239 from all channels when the client entry is being destroyed.
2240 Affected file lib/silcclient/client_notify.c, command.c.
2242 * Added auto-nicking support to the client library. If the
2243 applicatio now sets client->nickname it will be sent to the
2244 server after connecting by the library. This way for example
2245 SILCNICK (or IRCNICK) environment variables will have effect
2246 and always change the nickname automatically to whatever
2247 it is wanted. Affected file lib/silcclient/client.[ch].
2249 * Renamed silc_server_command_bad_chars to the
2250 silc_server_name_bad_chars and moved it to the
2251 silcd/server_util.[ch]. Added also new function
2252 silc_server_name_modify_bad to return nickname that
2253 includes bad characters as new nickname without those
2254 bad characters. This check and modify is now used in
2255 silc_server_new_client when the username is initially set
2256 as nickname, so it must be checked to be valid nickname.
2257 Affected file silcd/packet_receive.c.
2259 * The nickname length is now taken from the packet for real
2260 and not trusted to strlen() since it clearly can return
2261 wrong length for nickname including bad characters. This
2262 also applies to channel names. Affected file silcd/command.c.
2264 * Removed the lib/silcsilm/modules directory. Modules are now
2265 compiled into the lib/silcsim. Fixed the copying of the
2266 modules to follow symbolic links in Makefile.am.pre.
2268 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2270 * Fixed silc_string_regexify list creation. Fixes bugs with
2271 BAN and INVITE commands in server. The affected file is
2272 lib/silcutil/unix/silcunixutil.c.
2274 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Removed the command destructor entirely from the server's
2277 command and command reply routines. It is not needed, and
2278 its usage was buggy and caused crashes. Affected files are
2279 silcd/command[_reply].[ch].
2281 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Cancel protocol and NULL sock->protocol if timeout
2284 occurred during protocol. Affected file silcd/server.c.
2286 * Cancel protocol timeouts always before calling the final
2287 callback, to assure that after final callback is called
2288 no other state will be called for the protocol anymore.
2289 Affected file silcd/protocol.c.
2291 * Print error log if incoming connection configuration could
2292 not be found. Affected file silcd/server.c.
2294 * Fixed JOIN command to correctly save the founder mode
2295 to the client on normal SILC server, when the channel
2296 was created by the router. Affected file silcd/command.c.
2298 * Fixed LIST command (hopefully) to send correct reply
2299 packets. Affected file silcd/command.c.
2301 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * The silc_packet_receive_process now returns FALSE if the
2304 read data was invalid packet, and TRUE if it was ok.
2306 The server now checks that if unauthenticated connection
2307 sends data and its processing fails the server will close
2308 the connection since it could be a malicious flooder.
2310 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2312 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Make sure the warning about error opening a log file is
2315 printed only once and not everytime it fails (produces
2316 too much useless log). Affected file lib/silcutil/silclog.c.
2318 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2320 * Made the silc_server_daemonise() function more readable.
2321 Affected file silcd/server.c.
2323 * Pid file is now optional, the user may comment it out from
2324 the config file. Removed define SILC_SERVER_PID_FILE, we
2325 don't need a default any longer. Affected file
2326 configure.in.pre, lib/Makefile.am.pre.
2328 * Make some use of the pid file. The server now dies at startup
2329 if it detects a valid pid file on his path. The server would
2330 die anyway in this circumstance, because of the bind() failure.
2331 Affected file silcd/silcd.c.
2333 * No longer compiling lib/dotconf.
2335 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Fixed JOIN command parsing not to crash. Affected file
2338 lib/silcclient/command.c.
2340 * Fied the NICK_CHANGE notify to add the new client entry
2341 even it is resolved. This removes an <[unknown]> nick
2342 thingy bug in the client. Affected file is
2343 lib/silcclient/client_notify.c.
2345 * Do not try to allocate 0 bytes (efence does not like it)
2346 in lib/silccore/silccomand.c when encoding payload.
2348 * Do not take IRCNICK as nickname in Irssi SILC client since
2349 it is not possible to set nickname before hand connecting
2350 the server (TODO has an entry about adding auto-nicking
2353 * Changed the silc_server_command_pending to check whether
2354 there already exists an pending entry with the specified
2355 command, command identifier and pending callback. This is
2356 to fix IDENTIFY and WHOIS related crashes that may register
2357 multiple pending commands with same identifier. Affected
2358 file silcd/command.c.
2360 * Fixed the server to reconnect to the router even if it
2361 was already reconnecting and EOF was received. This to
2362 fix a possibility that the server wouldn't ever try to
2363 auto-reconnect to the router. Affected file silcd/server.c.
2365 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Fixed the server's password authentication to use the
2368 length of the locally saved password, and not the one
2369 sent in the packet. Affected file silcd/protocol.c.
2371 * Fixed same password authentication problem in the
2372 Authentication Payload handling routines in
2373 lib/silccore/silcauth.c.
2375 * Yet another password authentication problem fixed with
2376 channel password handling in silcd/command.c.
2378 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * If first character of string in silc_parse_userfqdn is '@'
2381 then do not parse it. Affected file is
2382 lib/silcutil/silcutil.c.
2384 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Fixed minor bug in IDENTIFY command reply sending, which
2387 caused various weird problems during JOIN when it was
2388 resolving names for users. Affected file silcd/command.c.
2390 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Fixed the IDENTIFY command reply sending to chech better valid
2393 clients. It was possible to send incomplete list of replies.
2394 Affected file silcd/command.c.
2396 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Added silc_client_command[s]_[un]register functions now to
2399 dynamically register the commands in client library. Removed
2400 the static table of commands. This allows the client library
2401 to call commands without causing the application to know about
2402 what commands library has called.
2404 Removed the INFO command reply kludge to detect when the command
2405 was called by library. Now library use its own command reply
2406 function for INFO command.
2408 Added function silc_client_command_call to call a command.
2409 Application can use it to call command, not access the structure
2412 Now all commands that are sent by the client library (not
2413 explicitly sent by application) use own command reply functions.
2415 Affected files around lib/silcclient/ and in
2416 irssi/src/silc/core/.
2418 * Fixed the WHOIS command reply sending to chech better valid
2419 clients. It was possible to send incomplete list of replies.
2421 Fixed the WHOIS and IDENTIFY to send the request to router
2422 if normal server did not do it and did not find any results.
2424 Affected file silcd/command.c.
2426 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Moved the internal data from SilcClient context into its
2429 own file, not accesible to application. Affected files
2430 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2431 and other files in client library.
2433 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Added doc/examples installation target in Makefile.am.pre.
2438 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2441 commands the found client entry will be removed from the
2442 cache, after notifying application about the error. Affected
2443 file lib/silcclient/command_reply.c.
2445 * Changed the /MSG to check for exact nickname user gave, and
2446 not let `nick' match `nick@host' if it is only one found. Now,
2447 user must type the exact nickname (like nick@host2) even if
2448 there are no more than one same nicks found. This is to avoid
2449 a possibility of sending nickname to wrong nickname since
2450 `nick' could match `nick@host'. Affected file is
2451 irssi/src/core/silc-servers.c.
2453 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Do not print "you are now server operator" or similar when
2456 giving /away command. Affected files are
2457 irssi/src/silc/core/client_ops.c, silc-servers.h.
2459 * Made the silc_server_command_pending_error_check to send
2460 the same command reply payload it received back to the
2461 original sender of the command. This way all arguments
2462 that was received by the server will be received by the
2463 client too. Affected file silcd/command.c.
2465 * Added the silc_idcache_add to return the created cache entry
2466 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2468 * Add global clients to expire if they are not on any channel.
2469 This is because normal server will never know if they signoff
2470 if they are not on any channel. The cache expiry will take
2471 case of these entries. This is done by normal servers only.
2472 The affected files are silcd/command_reply.c,
2473 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2475 * If server receives invalid ID notification for WHOIS or
2476 IDENTIFY and the ID exists in the lists, it is removed.
2477 Affected file silcd/command_reply.c.
2479 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2480 in client then client entry that it matches is searched and
2481 the nickname is printed on the screen for user. Affected
2482 file irssi/src/silc/core/client_ops.c.
2484 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Use cache entry expire time in the LIST command reply to
2487 purge old entries from the cache after the LIST command
2488 reply has been received. This way we don't have non-existent
2489 entries in the cache for too long. Affected file is
2490 silcd/command_reply.c.
2492 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * If we are normal server, and we've not resolved client info
2495 in WHOIS or IDENTIFY from router, and it is global client,
2496 we'll check whether it is on some channel. If it is not
2497 then we cannot be sure about its validity and will resolve it
2498 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2499 file silcd/command.c.
2501 * Search channel by name (if possible) rather than by ID
2502 in IDENTIFY command's command reply. Affected file is
2503 silcd/command_reply.c.
2505 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2508 Updated specs and implemented it. Affected file silcd/command.c,
2509 silcd/packet_send.c and silcd/packet_receive.c.
2511 * Implemented the <founder auth> payload handling in the JOIN
2512 command. If provided all conditions for channel joining
2513 except requirement to provide correct passphrase can be
2514 overrided by the channel founder. Updated the protocol specs.
2515 Affected file silcd/command.c.
2517 Added support for founder auth in JOIN command in client
2518 library. Fixed the parsing of the JOIN command now to support
2519 all options as they should be. The affected file is
2520 lib/silcclient/command.c.
2522 * Optimized the WHOIS and IDENTIFY commands to send the request
2523 to router only if it includes nicknames or other names. If
2524 they include only IDs then check the local cache first before
2525 routing. Affected file is silcd/command.c.
2527 * Added channels topic announcements. Affected file is
2528 silcd/packet_receive.c and silcd/server.c.
2530 * Fixed the silc_server_send_notify_topic_set to really destine
2531 the packet to channel. Affected file silcd/packet_send.c.
2533 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2534 library. Affected file lib/silcclient/client_notify.c.
2536 * Added UMODE announcements. Affected file silcd/server.c.
2538 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Memory leak fixes in:
2542 lib/silcutil/silcsockconn.c
2543 lib/silcske/silcske.c
2544 lib/silcske/groups.c
2546 lib/silccrypt/silcpkcs.c
2547 lib/silccore/silccommand.c
2548 lib/silccore/silcidcache.c
2553 * ROBOdoc documented the lib/silcske/groups.h file and a
2554 bit changed the interface for better.
2556 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2558 * Update the client entry context in the ID cache after
2559 nick change. Affected file lib/silcclient/command.c.
2560 Fixes the CUMODE command when regaining founder privileges,
2561 and a little WHOIS problem.
2563 * Fixed silc_net_gethostbyname to correctly call the
2564 inet_ntop. Affected file lib/silcutil/silcnet.c.
2566 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2568 * Added IPv6 support checking to the configure.in.pre, added
2569 also --enable-ipv6 option to override the check. Affected
2570 file configure.in.pre.
2572 * The silc_thread_create now calls the start function
2573 directly if threads support is not compiled in. Removes
2574 ugly #ifdef's from generic code. Affected files are
2575 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2577 * Added silc_net_gethostby[name/addr]_async to asynchronously
2578 resolve. Affected files are lib/silcutil/silcnet.[ch].
2580 * Added support for rendering IPv6 based server, client and
2581 channel IDs. Affected file lib/silcutil/silcutil.c.
2583 * Added support for creating IPv6 based server IDs. Affected
2584 file is silcd/serverid.c.
2586 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2588 * Added silc_net_gethostby[addr/name] into the
2589 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2590 routines. Added silc_net_is_ip[4/6]. Affected file is
2591 lib/silcutil/unix/silcunixnet.c. All routines that take
2592 address as argument now supports both IPv4 and IPv6 addresses.
2594 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2596 * Fixed LIST command reply sending in server. Affected file
2599 * Server now sends the kicker's client ID in the KICK notify
2600 to the kicked client. Affected file silcd/command.c.
2602 * The client library now parses the kickers client ID and
2603 UI displays it. Affected files lib/silcclient/client_notify.c
2604 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2606 * Made all payload parsing function prototypes consistent.
2607 They all take now const unsigned char * and uint32 pair as
2608 the payload data instead of SilcBuffer. Changes all around
2609 the source tree. Other unsigned char* -> const unsigned char*
2610 changes around the tree as well.
2612 * Optimized SFTP client and server packet sending not to
2613 allocate new buffer for each packet but to recycle the
2614 first allocated buffer. Affected files are
2615 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2617 * Optimized the SFTP client to use SilcList instead of
2618 SilcDList for requests, because it is faster. Affected file
2619 is lib/silcsftp/sftp_client.c.
2621 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2622 into lib/silccore/silcid.[ch].
2624 Renamed silcpayload.[ch] into silcargument.[ch].
2626 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * If client entry is deleted with active key agreement
2629 session, abort the session.
2631 The silc_client_abort_key_agreement now calls the completion
2632 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2634 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2637 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Don't use __restrict in older GCC's. Affected file is
2640 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2642 * silc_net_localhost now attempts to reverse lookup the
2643 IP/hostname. Affected file lib/silcutil/silcnet.c.
2645 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2646 command. It can be used to gain founder privileges at
2647 the same time when joining the channel.
2649 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2650 kicker's client ID as well. Updated protocol specs.
2652 Defined that the server must send SILC_COMMAND_IDENTIFY
2653 command reply with error status to client who sent
2654 private message with invalid client ID.
2656 Updated the protocol specification.
2658 * Added silc_server_send_command_reply to send any
2659 command reply. Affected file silcd/packet_send.[ch].
2661 * Added silc_id_payload_encode_data to encode ID payload
2662 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2664 * The server now send IDENTIFY command reply with error
2665 status if client ID in private message is invalid. Affected
2666 file silcd/packet_receive.c.
2668 * Save the server key file with server's IP address in
2669 the filename instead of hostname. The affected file is
2670 irssi/src/silc/core/client_ops.c.
2672 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2677 * Added libtool support for compiling shared objects in
2678 lib/silcsim. Affected file configure.in.pre and
2679 lib/silcsim/Makefile.am. Original patch by cras.
2681 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Pid file configuration, and server's config file fixes
2684 patch by toma. Updated CREDITS file.
2686 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Fixed silc_client_channel_message to not try to decrypt
2689 the message twice if it resolved the destination client
2690 information. This could cause of dropping one channel
2691 message. Affected file lib/silcclient/client_channel.c.
2693 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2696 lib/silcclient/client.c. This function is used when the SILC
2697 Client is run under some other scheduler, or event loop or
2698 main loop. On GUI applications, for example this may be
2699 desired to used to run the client under the GUI application's
2700 main loop. Typically the GUI application would register an
2701 idle task that calls this function multiple times in a second
2702 to quickly process the SILC specific data.
2704 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2706 * Fixed silc_server_drop() for dropping the supplementary
2707 groups as well, this could cause a security hole on some
2710 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2715 * Write PID file after dropping privileges. Added -F option
2716 to run server on foreground. A patch by debolaz.
2717 Affected files silcd/server.c, silcd/silcd.c.
2719 * Fixed MOTD to return the MOTD file server name. Affected
2720 file silcd/command.c.
2722 * Added INFO command reply handling to the Irssi SILC Client.
2723 Affected file irssi/src/silc/core/client_ops.c.
2725 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Fixed the silc_idcache_list_* routines to really support
2728 the dynamic list. Fixes a crash. Affected file is
2729 lib/silccore/silcidcache.c.
2731 * Fixed the LIST command reply to really call LIST command's
2732 pending callbacks. Affected file silcd/command_reply.c.
2734 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Update conn->local_entry->nickname after giving NICK
2737 command. Affected file lib/silcclient/command.c.
2739 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2741 * Added the [pid] option to the silcd configuration file
2743 Affected files: serverconfig.[ch] and silcd.c
2745 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Save fingerprint in WHOIS command reply in server.
2748 Affected file silcd/command_reply.c.
2750 * Fixed NICK commands pending callback registration.
2751 Affected file lib/silcclient/command.c.
2753 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Use ++server->cmd_ident when sending commands in server,
2756 instead of random number. Affected file silcd/command.c.
2758 * Fixed GETKEY command reply to call actually GETKEY pending
2759 command callbacks. Affected file silcd/command_reply.c.
2761 * A bit stricter check for nicknames. Check for same nickname
2762 in NICK command also. Affected file silcd/command.c.
2764 * Do not call INFO command everytime client ID changes, only
2765 during first connecting. Affected file lib/silcclient/client.c.
2767 * Set the new nickname only after successful command reply for
2768 NICK command is returned by server. Affected file
2769 lib/silcclient/command.c.
2771 * Remove nicknames from nicklist during server_signoff notify.
2772 Should fix /NAMES bit more. The affected file is
2773 irssi/src/silc/core/silc-channels.c.
2775 * Added `fingerprint' field to the SilcIDListData in the
2776 silcd/idlist.h to hold the fingerprint of the client's
2779 Send the fingerprint of the client's public key in WHOIS
2782 Affected files silcd/command.c, and silcd/idlist.[ch].
2784 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2785 create fingerprint from given data.
2787 * Show the fingerprint of the client's public key in WHOIS.
2788 Affected files irssi/src/module-formats.[ch] and
2789 irssi/src/silc/core/client_ops.c.
2791 * Format the multiple same nicknames also during JOIN and
2792 NICK_CHANGE notifys. Affected file is
2793 lib/silcclient/client_notify.c.
2795 * Do not print error on screen for invalid private message
2796 payload since it can come if someone is sending private
2797 messages with wrong key. Affected file
2798 lib/silccore/silcprivate.c.
2800 * Fixed multiple concurrent /PING crash. Affected file
2801 lib/silcclient/command.c.
2803 * Changed the wrong ID encoding. All IP addresses must be
2804 in MSB first order in encoded format. They were encoded
2805 wrong and was in LSB format. Affected files are
2806 silcd/serverid.c, lib/silcutil/silcutil.c.
2808 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2810 * Call the `connect' client operation through the scheduler
2811 in case of error. Affected file lib/silcclient/client.c.
2813 * Call the `failure' client operation even if the error
2814 occurred locally during a protocol. Affected file is
2815 lib/silcclient/protocol.c.
2817 * Added support of sending LIST command to router from normal
2818 server. This way normal server can get list of all channels
2819 in the network too. Fixed the channel list sending in the
2820 server too. Affected files are silcd/command.c, and
2821 silcd/command_reply.[ch].
2823 * Added silc_server_update_channels_by_server and
2824 silc_server_remove_channels_by_server. They are used during
2825 disconnection of primary router and in backup router protocol.
2826 Affected file silcd/server_util.[ch], silcd/server.c and
2827 silcd/server_backup.c.
2829 * Fixed channel adding to global list in IDENTIFY command
2830 reply in server. Affected file silcd/command_reply.c.
2832 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * If the incoming packet type is REKEY or REKEY_DONE process
2835 that packet always synchronously. Fixes yet another MAC
2836 failed error on slow (dialup) connections. Affected file
2837 lib/silcclient/client.c and silcd/server.c.
2839 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Call check_version SKE callback for initiator too. Affected
2842 file lib/silcske/silcske.c.
2844 * Implemented fix for security hole found in the SKE that was
2845 fixed in the specification few days back; the initiator's
2846 public key is now added to the HASH value computation.
2847 Added backwards support for the old way of doing it too, for
2848 old clients and old servers. Affected file is
2849 lib/silcske/silcske.c.
2851 * Enabled mutual authentication by default in SKE. If initiator
2852 is not providing mutual authentication the responder will
2853 force it. This will provide the proof of posession of the
2854 private key for responder. The affected files are
2855 lib/silcclient/protocol.c and silcd/protocol.c.
2857 * Do not cache anymore the server's public key during SKE.
2858 We do mutual authentication so the proof of posession of
2859 private key is done, and if the server is authenticated in
2860 conn auth protocol with public key we must have the public
2861 key already. Affected file silcd/protocol.c.
2863 * Added new global debug variable: silc_debug_hexdump. If
2864 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2865 file lib/silcutil/silclog.[ch].
2867 * Fixed compilation warning due to char * -> const char *.
2868 Affected files lib/silcutil/silcnet.h, and
2869 lib/silccore/silcauth.[ch].
2871 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Fixed CMODE command when new channel key was created. If
2874 the creation failed the old key was removed. Next time giving
2875 same command would crash the server since the old key was
2876 freed already. Affected file silcd/command.c.
2878 * Fixed the silc_server_announce_get_channels to not crash
2879 on reconnect. Affected file silcd/server.c.
2881 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Added silc_log_set_debug_string function to set a regex
2884 string to match for debug output. Only the function names,
2885 or filenames matching the given debug string is actually
2886 printed. This way it is possible to filter out those debug
2887 strings that user is not interested in.
2889 Fixed a bug in silc_string_regexify.
2891 Affected files lib/silcutil/silclog.[ch], and
2892 lib/silcutil/unix/silcunixutil.c.
2894 * Changed the -d options in both server and Irssi SILC client
2895 to take the debug string as argument. Affected files
2896 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2898 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Added silc_hash_babbleprint to create a Bubble Babble
2901 Encoded fingerprint. The encoding is developed by Antti
2902 Huima (draft-huima-babble-01.txt), and it creates human
2903 readable strings out of binary data. Affected file
2904 lib/silccrypt/silchash.[ch].
2906 * Print the babble print now in addition of fingerprint as well
2907 in Irssi SILC client. Affected files are
2908 irssi/src/fe-common/silc/module-formats.[ch],
2909 irssi/src/fe-common/silc/core/client_ops.c.
2911 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Fixed a security problem found in SKE. The initiator's
2914 public key too is now added to the HASH hash value creation
2915 which is signed by the responder to create the SIGN value.
2916 This will prevent anyone in the middle to lie to the responder
2917 about the initiator's public key. If this is done now, the
2918 man in the middle will get caught. Updated the protocol
2921 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Better installation directory handling. Configure module
2924 paths and other paths automatically to example_silc* files
2925 in doc/. A patch by toma.
2927 * Fixed compiler warning from MPI library, and from SILC RNG.
2930 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2931 It can be configured with ./configure. A patch by toma.
2933 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Find correct make to use in prepare-clean. A patch by
2936 toma. Affected file prepare-clean.
2938 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2940 * Added irssi variables use_auto_addr, auto_bind_ip,
2941 auto_bind_port and auto_public_ip.
2943 * Changed the interface for silc_client_send_key_agreement
2944 in lib/silcclient/silcapi.h
2948 irssi/src/silc/core/silc-core.c
2950 lib/silcclient/silcapi.h
2951 irssi/src/silc/core/silc-channels.c
2952 lib/silcclient/client_keyagr.c
2955 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Added silc_pkcs_public_key_compare to compare two
2958 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2960 * Check that the client who set the founder mode on the
2961 channel is the same client that is giving the founder
2962 mode to itself. It is done by comparing the saved public
2963 key (it is saved even in the authentication is passphrase).
2964 Affected file silcd/command.c.
2966 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Do not process packet for disconnected socket connection.
2969 Affected file lib/silccore/silcpacket.c.
2971 * Process the DISCONNECT packet through scheduler in the
2972 client library. Affected file lib/silcclient/client.c.
2974 * Fixed the silc_client_packet_parse to not to increase
2975 the packet sequence number if the conn->sock and the
2976 current socket connection is not same. This can happen
2977 for example during key agreement when the conn includes
2978 multiple socket connections (listeners). Affected file
2979 lib/silcclient/client.c.
2981 * The sender of the file transfer request now provides also
2982 the pointer (listener) for the key exchange protocol. If
2983 the listener cannot be created then it sends empty key
2984 agreement and lets the receiver provide the listener.
2986 Added `local_ip' and `local_port' arguments to the
2987 silc_client_file_send. If they are provided they are used,
2988 if not then it will attempt to find local IP address, if
2989 not found or bind fails then the remote client will provide
2992 Affected files are lib/silcclient/client_ftp.c and
2993 lib/silcclient/silcapi.h.
2995 * Extended the FILE SEND command to support defining the
2996 local IP and port for key exchange listener. They are
2997 optional. Affected file irssi/src/silc/core/silc-servers.c.
2999 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Defined to WHOIS command reply the sending of fingerprint
3002 of the client's public key (if the proof of posession of the
3003 corresponding private key is verified by the server).
3004 Updated to the protocol specification.
3006 * Added support of receiving the client's public key's
3007 fingerprint in command reply in client library. Affected
3008 file is lib/silcclient/command_reply.c, and
3009 lib/silcclient/idlist.[ch].
3011 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Do not send over 128 chars long nickname to the server
3014 in NICK command. Affected file lib/silcclient/command.c.
3016 * Do not send over 256 chars long channel names to the server
3017 in JOIN command. Affected file lib/silcclient/command.c.
3019 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Assure that silc_server_close_connection cannot be called
3022 twice for same socket context. Affected file is
3025 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Send error message to application if opening file for
3028 writing during file transfer fails. Affected file is
3029 lib/silcclient/client_ftp.c.
3031 Remove all file transfer sessions for a client that we're
3032 removing from ID cache.
3034 Affected file is lib/silcclient/client_ftp.c.
3036 * Fixed silc_net_addr2bin to return correct address. Affected
3037 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3039 * Fixed file transfer session removing on signoff notify.
3040 Affected file irssi/src/silc/core/silc-servers.c.
3042 * Added the SilcClientFileError to be returned in the monitor
3043 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3044 Affected file lib/silcclient/silcapi.h.
3046 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Fixed a crash in silc_client_ftp_free_sessions and
3049 silc_client_ftp_session_free_client. Affected file
3050 lib/silcclient/client_ftp.c.
3052 * Added `disabled' field in the SilcChannelEntry in the server
3053 to indicate if the server entry is disabled. Affected file
3054 silcd/idlist.h, silcd/command[_reply].c.
3056 * SILC server adds now /var/run/silcd.pid everytime it is
3057 started. Affected file silcd/silcd.c.
3059 * Added silc_server_packet_send_clients to send a packet to
3060 the provided table of client entries. Affected file
3061 silcd/packet_send.[ch].
3063 * Fixed a crash in client resolving in client_prvmsg.c in
3064 client library. Affected file lib/silcclient/client_prvmsg.c.
3066 * Do not actually remove the client directly from ID cache
3067 during SERVER_SIGNOFF, but invalidate it. This way we
3068 preserve the WHOWAS info for the client. Affected file
3069 silcd/server_util.c.
3071 * Fixed SERVER_SIGNOFF notify handling in the server. The
3072 server is now able to process incoming SERVER_SIGNOFF notify
3073 for a server that it doesn't even know about. It will remove
3074 the clients provided in the notify. Affected file
3075 silcd/packet_receive.c.
3077 * Check for partial packet in data queue after every packet that
3078 was found from the queue. Return and wait for more data if
3079 there is partial data in queue. Affected file is
3080 lib/silccore/silcpacket.c.
3082 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Added SilcClietFileError enum to indicate error in
3085 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3086 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3087 Affected files lib/silcclient/silcapi.h and
3088 lib/silcclient/client_ftp.c.
3090 * Check that newsize in silc_buffer_realloc is larger than
3091 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3093 * Added better monitor of file transfers. It now monitors
3094 key agreement protocol during the file transfer too. Added
3095 error reporting too. Affected files
3096 irssi/src/silc/core/silc-servers.c,
3097 irssi/src/fe-common/silc/module-formats.[ch].
3099 * Wrote a help file for FILE command.
3101 * Added silc_rng_global_get_byte_fast to get not-so-secure
3102 random data as fast as possible. Random data is read from
3103 /dev/urandom if available and from the SILC RNG if not
3104 available. It is used in padding generation. Affected file
3105 lib/silccrypt/silcrng.[ch].
3107 * All packets in client library are now processed synchronously.
3108 Optimized packet processing a lot. Affected file
3109 lib/silcclient/client.c.
3111 * All server connection packets are processing synchronously
3112 now in server, to optimize packet processing. Affected file
3115 * Include files are installed now only in Toolkit distribution
3116 if make install is given. Affected files: all Makefile.am's.
3118 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Assure that silc_client_notify_by_server_resolve does not
3121 resolve the client information multiple times. If it cannot
3122 be found by the first it cannot be found at all. Affected
3123 file lib/silcclient/client_notify.c.
3125 * Fixed WHOWAS command reply calling. Affected file
3126 lib/silcclient/command_reply.c.
3128 * Removed all references to silc_idlist_get_client from the
3129 Irssi SILC client since that call is internal call used by
3130 the library. The Irssi SILC client will use now client
3131 retrieval functions found in silcapi.h.
3133 * Fixed a bug in resolving nickname info before sending
3134 private message. It used freed memory. Affected file
3135 irssi/src/silc/core/silc-servers.c.
3137 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Assure my_channels statistics cannot go negative in server.
3140 Affected files silcd/server.c, silcd/server_util.c.
3142 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3146 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3156 * Added silc_net_localip to return local host's IP address.
3157 Affected file lib/silcutil/silcnet.[ch].
3159 * If key exchange or rekey protocol is active for a connection
3160 parse all packets syncronously since there might be packets
3161 in packet queue that we are not able to process without first
3162 processing packets before them. Affected file silcd/server,
3163 lib/silcclient/client.c.
3165 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3166 whether library should continue processing the packet.
3167 Affected file lib/silccore/silcpacket.h.
3169 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3170 SilcSFTPMonitorData to SFTP server to monitor various

3213 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3214 is incomplete and is being resolved, it won't be resolved
3217 Make sure also that USERS command reply does not resolve
3218 twice information. Affected file is
3219 lib/silcclient/command_reply.c.
3221 Make sure that silc_client_get_clients_by_list does not
3222 resolve twice same information.
3224 * Check for valid client->id in the silc_server_free_client_data.
3225 Affected file silcd/server.c.
3227 * Fixed /GETKEY nick@server not to crash if the server entry
3228 is not found. Affected file lib/silcclient/command.c.
3230 * Fixed the silc_server_check_cmode_rights to check the

3236 Affected file silcd/command.c.
3238 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3240 * Call the silc_server_udpate_servers_by_server in the
3241 primary router that comes back online in the backup resuming
3242 protocol. Otherwise it routes packets wrong. Affected file
3243 silcd/server_util.[ch], silcd/server_backup.c.
3245 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3247 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3248 lib/silcutil/silcbuffmt.[ch].
3250 * Redefined the SILC packet header to include the padding
3251 length. Affected file lib/silccore/silcpacket.[ch].
3253 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3254 length for maximum padding up to 128 bytes). Affected
3255 file lib/silccore/silcpacket.h.
3257 * Removed all backwards support for old 0.5.x MAC thingies.
3258 The SILC packet header change makes it impossible to be
3259 backwards compatible.
3261 * Send the ENDING packet with timeout in the backup resuming
3262 protocol. This is to assure that all routers has connected
3263 to the primary router. Affected file silcd/server_backup.c.
3265 * Changed the RNG to take the first IV from random data. It
3266 used to take it from zero actually. Changed the RNG also
3267 to use /dev/urandom during session. /dev/random is used
3268 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3270 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Changed the SILC packet header to have the first two bytes
3273 (the packet length) encrypted. Affected files aroung the
3274 code tree, lib/silccore/silcpacket.[ch]. Removed the
3275 SilcPacketCheckDecrypt callback. It is not needed anymore
3276 since the silc_packet_receive_process will determine now
3277 whether the packet is normal or special.
3279 * Implemented the unidirectional MAC keys. Affected files
3280 lib/silcske/silcske.c, silcd/protocol.c and
3281 lib/silcclient/protocol.c.

3285 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3286 lib/silcclient/protocol.c.
3288 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Allow backup router to announce servers. All servers
3291 announced by backup router are added to the global list
3292 automatically. Update hte server's socket to our primary
3293 router also when backup router announces a server.
3294 Affected file silcd/packet_receive.c.
3296 * Do not update the client->router in the function
3297 silc_server_udpate_clients_by_server if the client is on
3298 global list. We might fail to find any specific server
3299 for locally connected clients and local cell clients. They
3300 should still use the `from' and not `to' as client->router.
3301 This fixes backup router resuming protocol. Affected file
3302 silcd/server_util.c.
3304 * Decrease channel statistics count only if the channel
3305 deletion worked. Affected files are silcd/server.c and
3306 silcd/server_util.c.
3308 * Added silc_server_update_servers_by_server to update origin
3309 of all server entries. Used during backup router protocol.
3310 Affected files silcd/server_util.[ch], silcd/server.c. and
3311 silcd/backup_router.c.
3313 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3314 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3315 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3316 lib/silccrypt/silchmac.c.
3318 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Assure that router cannot reroute the same channel message
3321 to the sender. Affected file silcd/packet_receive.c.
3323 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Made better checks that the channel message is not sent
3326 to the router it came from. Affected file is
3327 silcd/packet_send.c. Fixed memory leak too.
3329 * Announce informations for incoming router connection, but
3330 only after checking if it is replaced by backup router.
3331 Affected file silcd/packet_receive.c.
3333 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3335 * Fixed the backup resuming protocol to work in multiple
3336 router environment. Affected file silcd/server_backup.c.
3338 * Route packet only to one router in the function
3339 silc_server_packet_send_to_channel. Affected file is
3340 silcd/packet_send.c.
3342 * Fixed silc_server_send_notify_dest to set the broadcast
3343 flag. Fixed the silc_server_send_notify_topic to actually
3344 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3345 Affected file silcd/packet_send.c.
3347 * Changed the SFTP Filesystem interface. Changed the
3348 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3349 the filesystem operation function. The SilcSFTPFilesystem
3350 is now a context that is allocated by all filesystem allocation
3351 functions and it already includes the operations structure
3352 and filesystem specific context. It is given as argument
3353 now to the silc_sftp_server_start. This made the interface
3354 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3355 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3357 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Changed the backup router adding and getting interfaces
3360 in the server. The router that will be replaced by the
3361 specified backup router is now sent as argument. Affected
3362 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3365 * Added silc_net_addr2bin_ne to return the binary form of
3366 the IP address in network byte order. Affected files
3367 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3369 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Check for existing server ID in silc_server_new_server
3372 and in silc_server_connect_to_router_final and remove the
3373 old entry if it exists. Affected file silcd/packet_receive.c,
3376 * Send the channel message always to only one router, either
3377 in upstream or downstream. Affected file is
3378 silcd/packet_send.c.
3380 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Wrote the definition of the backup resuming protocol to the
3383 protocol specification.
3385 * Removed one redundant channel key generation from normal
3386 server during joining procedure. Removed one redundant
3387 channel key sending from server to router during joining
3388 procedure. Affected file silcd/command.c.
3390 * Made minor bugfixes to the backup router resuming protocol.
3391 Affected file silcd/server_backup.c, server.c.

3396 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3399 * Implemented the backup resuming protocol that is used to
3400 resume the primary router position in the cell after the
3401 primary router comes back online. Affected files
3402 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3403 and silcd/server_util.[ch].
3405 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Sleep two (2) seconds after sending QUIT command to server.
3408 Affected file lib/silcclient/command.c.
3410 * Assure that if outgoing data buffer is pending do not force
3411 send any data. Affected file silcd/packet_send.c.
3413 * Assure that if outgoing data buffer is pending do not force
3414 send any data. Affected file lib/silcclient/client.c.
3416 * Implemented the backup router support when the primary router
3417 goes down. The servers and routers can now use the backup
3418 router as new primary router without loosing connectivity.
3420 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3423 in the server to indicate disabled entry. All data read
3424 from the connection will be ignored and no data is sent
3425 for entry that is disabled. Affected files are
3426 silcd/idlist.h, silcd/server.c.
3428 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Created SFTP client and server test programs in the
3431 lib/silcsftp/tests directory.
3433 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3435 * Implemented memory filesystem (virtual filesystem) for
3436 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3439 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Implemented the SFTP (SSH File Transfer Protocol) to the
3442 lib/silcsftp. It includes SFTP client and SFTP server
3445 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Moved lib/silccore/silcprotocol.[ch] to the
3448 lib/silcutil library.
3450 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3451 take variable argument list pointer as argument. Affected
3452 file lib/silcutil/silcbuffmt.[ch].
3454 * Added silc_buffer_set function that is used to set data
3455 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3456 Affected file lib/silcutil/silcbuffer.h.
3458 * Changed various routines in the core library to use the new
3459 silc_buffer_set instead of allocating new buffer only for
3462 * Added 64-bit value formatting and unformatting support to the
3463 silc_buffer_[un]format routines. Affected file is
3464 lib/silcutil/silcbuffmt.[ch].
3466 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3467 to includes/bitmove.h.
3469 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Fixed channel user mode saving in client library. Affected
3472 file lib/silcclient/command[_reply].c.
3474 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Defined the file transfer to the SILC Protocol. Added
3477 new packet type SILC_PACKET_FTP and defined File Transfer
3478 Payload. The mandatory file transfer protocol is SFTP
3479 (SSH File Transfer Protocol). Affected file in addition
3480 of the internet draft is lib/silccore/silcpacket.h.
3482 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3483 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3484 is used as part of backup router protocol when the primary
3485 router of the cell is back online and wishes to resume
3486 the position as primary router.
3488 * Redefined the MAC generation keys in the protocol. The
3489 same key is not used anymore in both direction. Both
3490 direction will now use different keys for sending and
3491 receiving. This fixes a potential security flaw. This
3492 change causes incompatibilities in the protocol.
3494 * Redefined also the MAC computation from the packet.
3495 An packet sequence number is now added to the MAC
3496 computation. This prevents possible replay attacks against
3497 the protocol. This change too causes incompatibilities
3500 Added `sequence' field to the SilcPacketContext to hold
3501 the current sequence number for the packet.
3503 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Added `created' field to the SilcIDListData in the file
3506 silcd/idlist.h to indicate the time when the entry was
3509 * Added `created' field to the SilcChannelEntry too. Affected
3510 file silcd/idlist.h.
3512 * Added `creation_time' aguments to all the announcement functions
3513 in the server. If it is provided then only the entries that
3514 was created after the provided time frame are actually
3515 announced. Affected file silcd/server.[ch].
3517 * The protocol says that the Channel ID's IP address must be
3518 based on the router's IP address. Added check for this in
3519 the silc_server_new_channel when processing incoming New Channel
3520 Payload. Affected file silcd/packet_receive.c.
3522 * Print out the correct version with --version in SILC client.
3523 Affected file irssi/src/silc/core/silc-core.c.
3525 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Fixed WHOWAS command to check for completnes of the client
3528 entry always, not just when the command is coming from client.
3529 Affected file silcd/command.c.
3531 * Added new function silc_server_packet_queue_purge to purge the
3532 outgoing data queue to the network. After the function returns
3533 it is guaranteed that the outgoing packet queue is empty.
3534 Affected file silcd/packet_send.[ch].
3536 * Purge the outgoing packet queue in the rekey protocol's final
3537 callback to assure that all rekey packets go to the network
3538 before quitting the protocol. Affected file silcd/server.c.
3540 * Added silc_client_packet_queue_parse as similar function as
3541 in server to the client library. The affected file is
3542 lib/silcclient/client.c.
3544 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Splitted silcd/server.c and created silcd/server_util.[ch]
3547 for utility functions.
3549 * Added new socket flag SILC_SF_DISABLED to indicate that the
3550 connection is open but nothing can be sent to or received from
3551 the connection. Affected file lib/silcutil/silsockconn.[ch].
3552 The checking for disabled socket is checked in the low level
3553 silc_socket_write and silc_socket_read functions.
3555 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Allow only nicknames and channel names that fits into the
3558 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3560 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * When processing JOIN command reply in server check that if
3563 the channel exists in our global list we'll move it the local
3564 list. Affected file silcd/command_reply.c.
3566 * Fixed the check whether client is joined on the channel already
3567 in JOIN command. Affected file lib/silcclient/command.c.
3569 * Fixed the JOIN command reply to check whether the channel
3570 already exists. Affected file lib/silcclient/command_reply.c.
3572 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Added silc_ske_status_string to map the SKE error numbers
3575 to readable strings. The affected files are
3576 lib/silcske/silcske[_status].[ch].
3578 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3580 * Do not show the private channels on the WHOIS channel list
3581 as it is not allowed by the protocol. The affected file is
3584 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Assure that the packet length digged from the actual packet
3587 is something sensible in the silc_packet_decrypt_rest_special
3588 in lib/silccrypt/silcpacket.c.
3590 * Free and NULL the allocated pointer in silc_hmac_alloc if
3591 the HMAC allocation fails. The affected file is
3592 lib/silccrypt/silchmac.c.
3594 * Print the selected security properties to the log files in
3595 the server. Affected file silcd/protocol.c.
3597 * Add SKE's reference counter even if calling the completion
3598 callback manually. Otherwise it goes negative, although it
3599 does not cause any problems. The affected file is
3600 lib/silcske/silcske.c.
3602 * Remove the client entry with short timeout after giving the
3603 KILL command. Affected file lib/silcclient/command.c.
3605 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3606 case all found clients are already disconnected (WHOWAS would
3607 found them) in the server. Affected file silcd/command.c.
3609 * Update the last_receive (time of last data received) to be
3610 updated only when received private or channel message so that
3611 the idle time showed in WHOIS makes more sense.
3613 * Added boolean field `valid' in to the SilcClientEntry in the
3614 client library to indicate whether the entry is valid or not.
3615 This fixes the nickname change bug on channel when changing
3616 the nickname to be same than the old (like nick to Nick) the
3617 nickname formatter doesn't set the new nick anymore to Nick@host.
3618 Affected file lib/silcclient/idlist.[ch].
3620 * Now actually fixed the nickname changing on disconnection.
3621 Added new function silc_change_nick to the Irssi SILC Client.
3622 Affected file irssi/src/silc/core/client_ops.c,
3623 irssi/src/silc/core/silc-nicklist.[ch].
3625 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Check that the public key exists in the GETKEY command before
3628 trying to encode it. Affected file silcd/command.c.
3630 * Print some notifications on received public keys with GETKEY
3631 command in the Irssi SILC Client. Affected files are
3632 irssi/src/fe-common/silc/module-formats.[ch],
3633 irssi/src/silc/core/client_ops.c.
3635 * Use IDENTIFY command to resolve the server information in the
3636 GETKEY command instead of INFO command. Affected file
3637 lib/silcclient/command.c.
3639 * All command reply functions in the client library now calls
3640 the pending command reply callbacks even if an error has
3641 occurred. The server has done this a long time and now it was
3642 time to move the client library to this as well. Now all
3643 errors can be delivered back to the pending command reply
3644 callbacks if necessary. Affected files are
3645 lib/silcclient/command[_reply].[ch].
3647 * Change the nickname on disconnection back to the username
3648 because in reconnect the server will enforce it to it anyway.
3649 Affected file irssi/src/silc/core/silc-servers.c.
3651 * Fixed a config file parsing bug in the Irssi SILC client.
3652 Affected file irssi/src/silc/core/clientconfig.c.
3654 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3656 * When printing the channel mode on JOIN, verify that the
3657 channel key and channel's HMAC are valid. Affected file
3658 irssi/src/silc/core/client_ops.c.
3660 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3663 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3664 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3666 * Removed channel key rekey task deleting from the function
3667 silc_server_save_channel_key. Affected file silcd/server.c.
3668 Added explicit timeout task context instead that is used to
3669 delete the task if we are registering a new task before the
3670 new task has elapsed.
3672 * When channel key rekey occurs the client library now saves
3673 the old channel key for a short period of time (10 seconds) and
3674 is able to use it in case some is still sending channel
3675 messages encrypted with the old key after the rekey. Affected
3676 file lib/silcclient/[idlist.h|client_channel.c].
3678 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Added check to the silc_server_new_id_real to not accept
3681 new ID if it is the sender's own ID. Affected file is
3682 silcd/packet_receive.c.
3684 * Assure that we do not announce ourself or the one we've
3685 sending our announcements when we're router and are announcing
3686 servers to our primary router. Affected file silcd/server.c.
3688 * Fixed silc_server_command_identify_check_client to assemble
3689 correct WHOIS packet. It send corrupted WHOIS packet and
3690 caused problem with router to router connections. Affected
3691 file silcd/command.c.
3693 Fixed also silc_server_command_whois_check the same way
3694 as for the IDENTIFY command.
3696 * Added new SilcIDListStatus to the server in the SilcIDListData
3697 structure. The status now includes the current status of
3698 the entry (like registered, resolved etc.). Affected file
3699 silcd/idlist.[ch]. Defined a bunch of different status types
3700 as well. This replaced the old boolean registered field as well.
3702 Added resolve_cmd_ident field to the SilcClientEntry structure
3703 too so that if the entry is for example being resolved so
3704 another command may attach to the same pending command reply
3705 without requiring to resolve the same entry again. This concept
3706 should optimize the WHOIS and the IDENTIFY resolving under
3707 heavy load by taking away unnecessary resolving for entries
3708 that are being resolved already.
3710 Added support for adding multiple pending commands for one
3711 command idenfier. Affected file silcd/command[_reply].[ch].
3713 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3714 before deleting the data. Otherwise the hash table will have
3715 freed data in comparison functions. Affected file is
3716 silcd/command_reply.c.
3718 * Fixed silc_idlist_replace_client_id to add the new entry to
3719 the cache with NULL nickname. Otherwise there will be invalid
3720 memory as the nickname after the nickname is freed. Affected
3721 file silcd/packet_receive.c.
3723 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3724 saved into wrong slots because the previous number of entries
3725 was not taken into account. Affected file silcd/idlist.c.
3726 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3728 * If we are router and we receive JOIN notify to a channel that
3729 does not have any users then notified client is marked as the
3730 channel founder, as it is it. The affected file is
3731 silcd/packet_receive.c
3733 * Added to the extended hash table API's table_del_*ext functions
3734 the destructor as argument too, so that the caller can decide
3735 which destructor to use or whether to use destructor at all.
3736 Affected file lib/silcutil/silchashtable.[ch].
3738 * Fixed ID Cache purging. It actually deleted the entries from
3739 the hash table after the data was freed. The hash table ended
3740 up comparing freed memory. The affected file is
3741 lib/silccore/silcidcache.c.
3743 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Fixed Irssi SILC client's KILL command's HELP syntax.
3747 * The USERS command now resolves the detailed user information
3748 if the userinfo field is missing. Affected file is
3749 lib/silcclient/command_reply.c.
3751 * Do not print error in silc_file_read if the read file does
3752 not exist. Just silently return NULL. Affected file is
3753 lib/silcutil/silcutil.c.
3755 * Fixed the silc_log_output to not wine about NULL filename
3756 and to not create some bogus " " filename. Affected file is
3757 lib/silcutil/silclog.c.
3759 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3761 * Fixed various printing bugs on the user interface in the
3762 Irssi SILC Client. Minor changes that were forgotten from
3765 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Fixed the configure.in.pre and the compilation and distribution
3768 environment to support the new autoconf 2.52. That version is
3769 now required to compile the CVS trunk.
3771 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3773 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3774 to generally parse user@fqdn format strings. Affected file
3775 lib/silcutil/silcutil.c.
3777 * Added nickname_format and nickname_force_format fields to the
3778 SilcClientParams structure. The first one defines the format
3779 for the nicknames that the library will enforce if the receives
3780 multiple same nicknames. The second one is boolean value and
3781 can be used to force the library to always enforce the format
3782 to the nicknames regardles whether there are multiple nicknames
3783 or not. This configurable formatting was employed to flexibly
3784 support accessing multiple nicknames from the user interface.
3785 The userinterface can now set the nicknames to what ever format
3786 they prefer. Affected file lib/silcclient/silcapi.h.
3788 Added function silc_client_nickname_format to the file
3789 lib/silcclient/idlist.c. It performs the nickname formatting.
3791 Added new field `hostname´ to the SilcClientEntry context.
3792 It holds the hostname of the client. Affected file is
3793 lib/silcclient/idlist.h.
3795 * Irssi SILC Client sets the nicknames in nick@hostn format.
3796 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3797 irssi/src/silc/core/silc-core.c.
3799 The WHOIS printing now also shows both the real nickname and
3800 the formatted nickname so that user knows how to access the
3801 user if there are multiple same nicknames cached. Affected
3802 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3803 printing formatting too to take the hostname now as a separate
3804 argument. The Affected file is
3805 irssi/src/fe-common/silc/modules-formats.[ch].
3807 * Changed the silc_client_get_clients_local to accept the formatted
3808 nickname as argument. It accepts the real nickname too but the
3809 formatted nickname can be used to find the true entry from
3810 multiple entries. Affected file lib/silcclient/silcapi.h and
3811 lib/silcclient/idlist.c.
3813 * Added nickname_format_parse field to the SilcClientParams.
3814 It is a callback function provided by the application to parse
3815 the nickname out of the formatted nickname string. The library
3816 calls it to get the nickname from the formatted string. Since
3817 the application generally knows better the format of the nickname
3818 string it parses it instead of the library, even though library
3819 encodes the formatted string. If the callback function is not
3820 provided then the library will use the string as is. The
3821 affected file is lib/silcclient/silcapi.h.
3823 * All the nickname strings passed to the client library in
3824 commands are now expected to be formatted nickname strings.
3825 If the command does not support the formatted nickname string
3826 it will assume that the sent string is the actual nickname.
3827 Affected file lib/silcclient/command.c.
3829 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Added public key authentication support to OPER and SILCOPER
3832 commands in the client library. Affected file is
3833 lib/silcclient/command.c.
3835 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Changed the get_auth_methdod client operation to be asynchronous.
3838 It can be async if the application resolves the authentication
3839 method from the server during the negotiation. Added new
3840 SilcGetAuthMeth completion callback that the application will
3841 call after resolving the authentication method.
3843 Added function silc_client_request_authentication_method that
3844 the application can use to resolve the authentication method
3845 from the server. Added also SilcConnectionAuthRequest callback
3846 that the library will call after the server has replied. The
3847 application can call this function if it does not know the
3848 current authentication method.
3850 Affected files are lib/silcclient/client.c and
3851 lib/silcclient/silcapi.h.
3853 * The Irssi SILC client now automatically resolves the authentication
3854 method incase any configuration information is not present (and
3855 currently there never is). The affected file is
3856 irssi/src/silc/core/client_ops.c.
3858 * Fixed public key authentication from the client library.
3859 Affected file lib/silcclient/protocol.c. Changed also the
3860 protocol specification about the public key authentication in
3861 the connection authentication protocol. The actual data to be
3862 signed is now computed with a hash function before signing.
3864 * Fixed the public key authentication from the server as well.
3865 Affected file silcd/protocol.c.
3867 * Removed the mlock()'s from the memory allocation routines.
3868 Affected file lib/silcutil/silcmemory.c. The ./configure does
3869 not check anymore for the mlock(). Affected file is
3872 * Fixed USERS command in server to allow the execution of the
3873 command for private and secret channels if the client sending
3874 the command is on the channel. Affected file silcd/command.c.
3876 * Fixed silc_client_get_clients_local to return the clients
3877 count correctly. It could return wrong value. Affected file
3878 lib/silcclient/idlist.c.
3880 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3883 types. The assembler optimizations seemed not to like 64-bit
3884 data types. The assmebler optimizations thus are now enabled
3885 also for BSD systems as opposed to only enable them for Linux.
3887 * Do not check for threads at all on BSD systems. Affected
3888 file configure.in.pre.
3890 * Removed -n and -h options from the Irssi SILC Client since
3891 they are not used in silc.
3893 * Fixed the prime generation to assure that the first digit
3894 of the generated random number is not zero since our conversion
3895 routines does not like number strings that starts with zero
3896 digit. If zero digit is seen the random number is regenerated.
3897 This caused some corrupted RSA keys when the zero first digit
3898 was met. Affected file lib/silcmath/silcprimegen.c.
3900 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3902 * Fixed WIN32 configuration in the ./configure script.
3903 Fixed to include xti.h on environments that has it.
3904 Patches by Carsten Ilchmann and andrew.
3906 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3908 * Changed the silc_id_create_client_id to be collision
3909 resistant. It is now assured that there cannot be created
3910 two same client ID's. I suspect that some weird bugs in
3911 the server were actually caused by duplicate Client IDs.
3912 Affected file silcd/serverid.[ch]. A router receiving
3913 new ID now also assures and informs the sending server
3914 if the ID caused collision.
3916 * Changed the silc_id_create_channel_id to also assure that
3917 there are no collisions.
3919 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Statement about ignoring the Mutual Authentication flag when
3922 performing rekey with PFS was a bit misleading. It is ignored
3923 if it was set in the initial negotiation, it cannot be even
3924 set in the rekey. Fixed in the ke-auth draft. Started the
3925 new versions of the protocol drafts in the doc/.
3927 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Fixed a bug in silc_client_command_identify_save when saving
3930 new channel information. The channel name was no duplicated
3931 and caused crash on exit. Affected file is
3932 lib/silcclient/command_reply.c.
3934 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Fixed the getkey command handling in the server. Send just
3937 empty OK reply to the sender if the key could not be fetched
3938 (but everything else was ok, like the key just was not available).
3939 Changed the public key parameter to optional in the protocol
3940 specs so that empty OK reply can be sent. Affected file
3943 Added a message to Irssi SILC client to tell to user if the
3944 server did not return a public key.
3946 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Fixed a channel key regeneration bug. It registered new
3949 timeout tasks exponentially until all system resources were
3950 used. Affected file silcd/server.c.
3952 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Added the SILC Document generator to the scripts/silcdoc.
3955 It can be used to generate the Toolkit Reference Manual out
3956 of the source tree. Internally it will also use the RoboDoc
3957 generator now imported in util/robodoc.
3959 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Added couple of return's in rekey protocol if error orccurred
3962 during the protocol. The execution must be terminated.
3963 Affected file silcd/protocol.c. Also, terminate the protocol
3964 always with timeout.
3966 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * The client's Client ID was created initally from the wrong
3969 nickname (it could have been in format nick@host) in the
3970 silc_server_new_client. Affected file silcd/packet_receive.c
3972 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3974 * Added some SILC_LOG_ERROR's to various error conditions
3975 if client could not be added to ID cache. Affected files
3976 silcd/packet_receive.c and silcd/server.c.
3978 * When client's sock->user_data is freed, NULL also the
3979 client->router and client->connection pointers. Added check
3980 for these pointers being NULL to various places around the
3981 code. Affected file silcd/server.c.
3983 * Added client->data.registered == TRUE checks to various
3984 places around the code to assure that unregistered client's
3985 are not handled when it is not allowed. Affected file
3988 * Added `bool registered' fields to all
3989 silc_idlist_[server|client]_get_* routines to indicate whether
3990 the fetched client needs to be registered or not. Affected
3991 file silcd/idlist.[ch].
3993 * Add your own entry as registered to the ID cache in the
3994 server. Affected file server.c.
3996 * Fixed a bug in silc_server_new_server. The SilcServer was
3997 set as the new server's context instead of SilcServerEntry.
3998 This naturally caused some weird bugs.
4000 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Do not delete the channel rekey task when adding it
4003 for in silc_server_create_channel_key.
4005 * Changed the silc_server_create_channel_key to return
4006 TRUE or FALSE to indicate the success of the channel key
4009 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Fixed MSVC++ project files and added missing files to
4012 Makefiles under win32/.
4014 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Do not add TCP_NODELAY flag if the operating system
4017 does not have it defined. Affected files are
4018 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4020 * Fixed buffer overflow from Irssi SILC Client. Affected
4021 file irssi/src/fe-common/core/themes.c.
4023 * Fixed double free in client library in the file
4024 lib/silcclient/client.c when disconnecting from server.
4026 * Applied double free patch from cras to Irssi SILC client.
4027 Affected files irssi/src/core/[modules/expandos].c
4029 * Fixed the disconnection handling to Irssi SILC Client.
4030 The application must call silc_client_close_connection
4031 in ops->connect client operation in case of failure of
4032 the connection. Affected file is
4033 irssi/src/silc/core/client_ops.c.
4035 * Do not set sock->protocol to NULL in the function
4036 silc_client_close_connection after executing the protocol's
4037 final callback since the sock might not be valid anymore.
4038 Affected file lib/silcclient/client.c.
4040 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Do not enable SILC_THREADS if the linking with libpthread
4043 did not happen. Affected file configure.in.pre.
4045 * Added notion to protocol specification that server must
4046 verify the sent authentication payload with CMODE when
4047 setting the channel founder key. Implemented it to the
4048 server. Affected file silcd/command.c.
4050 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Added _EXTRA_DIST SILC distribution variable to the
4053 distributions file. It is used to conditionally add extra
4054 files or directories to the specific distribution. Affected
4055 files ./prepare, Makefile.am.pre and distributions.
4057 Removed the `_' from the start of the distribution names.
4060 * Added README.WIN32 for instructions to compile the Toolkit
4063 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Fixed a double free in disconnection in the server. Affected
4066 file is silcd/server.c.
4068 * Fixed the lib/silcske/groups.c to work now also with GMP
4069 MP library. The string conversion did not work when using
4070 specific base and the base is indicated in the string as well.
4072 * Created win32/ directory which now includes MSVC++ specific
4073 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4074 It will appear only in the toolkit distribution
4076 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Changed the key material distribution function in case when
4079 the hash output is too short. The data is now concatenated
4080 a bit differently than it used to. Made the change to the
4081 SKE protocol specification.
4083 * Added better GMP detection to configure.in.pre. A patch
4086 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4088 * Fixed a minor bug in SKE that might cause some problem on
4089 some platforms. Affected file lib/silcske/silcske.c.
4091 * Added the cookie checking for initiator in the SKE. It checks
4092 that the responder returns the sent cookie unmodified. The
4093 affected file is lib/silcske/silcske.c. Added new SKE
4094 error type INVALID_COOKIE that can be sent during the
4095 negotiation. Fixed some memory leaks as well.
4097 * Added the "invalid cookie" error message to Irssi SILC client's
4100 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4102 * Added `task_max' field to the SilcClientParams to indicate
4103 the maximum tasks the scheduler can handle. If set to zero,
4104 default values are used. Affected file lib/silcclient/silcapi.h.
4106 * Fixed memory leaks in silc_client_close_connection. Affected
4107 file lib/silcclient/client.c.
4109 * Added silc_client_del_client_entry to client library to free
4110 all memory of given client entry. Affected file is
4111 lib/silcclient/idlist.[ch].
4113 * Added new functions silc_client_del_channel and
4114 silc_client_del_server to delete channel and server entries.
4115 Affected file lib/silcclient/[silcapi.h/idlist.c].
4117 * Removed silc_client_del_client_by_id from silcapi.h.
4119 * Fixed the INFO command to return the server's own info
4120 correctly when querying by Server ID. Affected file is
4123 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * Removed the non-blocking settings in WIN32 code in the
4126 silc_sock_[read/write] and added SleepEx instead. Affected
4127 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4128 of input data is now checked with FIONREAD and ioctlsocket.
4130 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Call silc_schedule_task_del_by_context in the
4133 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4134 Affected file lib/silccore/silcprotocol.c.
4136 * Call silc_protocol_cancel for active protocols in the
4137 silc_server_close_connection if the funtion
4138 silc_server_free_sock_user_data has not been called.
4139 Affected file silcd/server.c.
4141 * Generic tasks cannot be deleted using the del_by_fd
4142 task deleting function since generic tasks does not match
4143 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4145 * Added a notion to SILCOPER help file that the SILCOPER works
4146 only on router server, not on normal server.
4148 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4150 * Added for WIN32 support for the new scheduler as well.
4151 Affected file lib/silcutil/win32/silcwin32schedule.c.
4153 * Fixed the SHA1 implementation to work on various platforms.
4155 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4157 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4158 API. It is part of the scheduler now. Everything else is
4159 as previously but some functions has changed their names.
4160 Checkout the lib/silcutil/silcschedule.h for the interface.
4161 Updated all applications to use the new interface. Affected
4162 files are lib/silcutil/silcschedule.[ch].
4164 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4166 * Found a bug in the SKE implementation. The HASH value,
4167 specified by the protocol, was not computed correctly. The
4168 public key of the responder was not added to the computation
4169 even though it is mandatory. Affected file lib/silcske/silcske.c.
4170 This unfortunately causes incompatibilities with older
4171 clients and servers.
4173 * Added WIN32 specific network init and uninit functions:
4174 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4175 the Winsock2. Affected file lib/silcutil/silcnet.h and
4176 lib/silcutil/win32/silcwin32net.c.
4178 * Set the socket always to nonblocking mode on WIN32 after
4179 reading data or writing data. Affected file is
4180 lib/silcutil/win32/silcwin32sockconn.c.
4182 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * Fixed various compilation problems under WIN32. Affected
4185 files lib/silcutil/win32/silcwin32thread.c and
4186 lib/silcutil/win32/silcwin32schedule.c.
4188 * Removed all _internal.h #includes from public header
4189 files. Internal headers must never be included from
4192 Removed also the lib/silcske/payload_internal.h file.
4194 * All include files that may be needed (public and some others
4195 included by the public headers) by application developers are
4196 now copied to the ./includes directory. It does not copy any
4197 internal headers. Affected file Makefile.defines.pre and all
4198 Makefile.am's under lib/ and subdirs.
4200 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4202 * Do not change the ~/.silc directory's permissions automatically.
4203 Affected file irssi/src/silc/core/clientutil.c.
4205 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * Do not cancel the protocol in silc_server_close_connection
4208 it might cause recursion. Now cancelled in the function
4209 silc_server_free_sock_user_data. Affected file silcd/server.c.
4211 * Fixed the silc_server_remove_clients_by_server to regenerate
4212 the channel keys correctly finally. Added also new function
4213 silc_server_remove_clients_channels to actually do it.
4214 Affected file silcd/server.c.
4216 * Fixed the silc_server_new_channel to not crash by giving
4217 wrong router to the new channel. Affected file is
4218 silcd/packet_receive.c.
4220 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4222 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4223 which is given as argument to the silc_client_alloc now.
4224 It can be used to configure the client and set various parameters
4225 that affect the function of the client.
4227 * The USERS command in server did not check whether the channel
4228 is private or secret. Affected file silcd/command.c.
4230 * Added new argument to the USERS command in protocol specification.
4231 The USERS command now can take the channel name as argument
4232 as well. Added support for this in client and server and
4233 updated the protocol specs.
4235 * Completed the GETKEY command in client. It can be now used
4236 to fetch also servers public key not only some clients.
4237 Affected files lib/silcclient/command[_reply].c.
4239 * Added silc_client_get_server to return server entry by the
4240 server name. Affected files lib/silcclient/silcapi.h and
4243 * Redefined the IDENTIFY command in protocol specification to be
4244 more generic. It now can be used to query information about
4245 any entity in the SILC Network, including clients, servers and
4246 channels. The query may be based either the entity's name
4247 or the ID. Added support for this in both client and server.
4249 Affected files silcd/command.c and lib/silcclient/command.c
4250 and command_reply.c.
4252 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4253 the _from_client and _from_server functions. Affected file
4256 * Added silc_client_get_channel_by_id_resolve to the file
4257 lib/silcclient/silcapi.h to resolve channel information by
4258 its ID. Added also silc_client_get_channel_by_id that
4259 does not resolve it from the server.
4261 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4263 * Added SilcServerEntry context into the client library
4264 to represent one server. The INFO command now allocates
4265 these to save the resolved server info. For now on the
4266 client library will also keep information about servers,
4267 connected and resolved with INFO.
4269 The INFO command now allocates the SilcServerEntry context
4270 and saves the server info there. The COMMAND_REPLY in
4271 the INFO now returns the parameters to application in
4272 same order as defined in the protocol specification.
4274 The entries are cached in the client->server_cache.
4276 * The INFO command is now issued after received the Client ID
4277 from the server. Affected file lib/silcclient/client.c.
4279 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4280 to the application as the mode changer might be server.
4281 It is guaranteed that NULL is not returned anymore to the
4282 application. Affected file lib/silcclient/client_notify.c.
4284 The ID Type is now also passed to the application so that
4285 it can check whether the returned entry is SilcClientEntry
4288 Added new function silc_client_get_server_by_id to return
4289 the server entry by ID. Affected files are the
4290 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4292 * Do not create the channel in the Irssi SILC Client when issuing
4293 the JOIN command but when received the sucessful JOIN command
4294 reply. Otherwise the channel might get created even though we
4295 could not join it. The Affected file is
4296 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4298 * Fixed a channel joining bug in router. The router must also
4299 check the channel modes, invite and ban lists etc. when serving
4300 the JOIN command sent by normal server. Affected file is
4301 silcd/command.c. The router now resolves the client's
4302 information from the server who sent the JOIN command if it
4303 does not know it, and processes the JOIN command only after
4306 * Changed the SilcCommandCb to take new argument; void *context2.
4307 Affected file lib/silccore/silccommand.h
4309 The second argument in the command callbacks in the server now
4310 includes the SilcServerCommandReplyContext if the command was
4311 called as pending command callback from the command reply.
4312 Otherwise it is NULL. When called as pending the status of the
4313 command reply will be checked and if it was erronous the
4314 error will be sent to the original sender of the command.
4315 This way the client always receives the error messages even
4316 though the server was actually the one who received the error
4317 when it resent the command to router, for example. Affected
4318 files silcd/command[_reply].[ch].
4320 * Fixed sending WHOWAS command's error message to client if
4321 the requested client could not be found. It was missing.
4324 * Changed the CMODE and CUMODE commands reply arguments in the
4325 protocol specification. The Channel ID is now sent in both
4326 of the commands to identify the channel. Implemented this
4327 new feature to the client and server. Affected files
4328 lib/silcclient/command_reply.c and silcd/command.c.
4330 * Made better checks for invite and ban lists in the JOIN
4331 command in server. Affected file silcd/command.c.
4333 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4335 * The server now performs the incoming host IP/DNS lookup
4336 using the silc_socket_host_lookup and thus does not block
4337 the server anymore. Affected file silcd/server.c.
4339 * Completed the multi-thread support for SILC Scheduler in
4340 the lib/silcutil/silcschedule.c.
4342 * Fixed the configure.in.pre to detect the pthread correctly
4345 * Fixed a deadlock in silc_task_queue_wakeup in the file
4346 lib/silcutil/silctask.c.
4348 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Added new function silc_schedule_wakeup that is used in
4351 multi-threaded environment to wakeup the main thread's
4352 schduler. It needs to be used when a thread adds a new task
4353 or removes a task from task queues. After waking up, the
4354 scheduler will detect the task queue changes. If threads
4355 support is not compiled in this function has no effect.
4356 Implemented the wakeup mechanism to both Unix and WIN32
4357 systems. Affected files are lib/silcutil/silcschedule.[ch],
4358 lib/silcutil/unix/silcunixschedule.c and the
4359 lib/silcutil/win32/silcwin32schedule.c.
4361 * Added new function silc_task_queue_wakeup to wakeup the
4362 scheduler by the specified task queue. Affected file
4363 lib/silcutil/silctask.[ch].
4365 * The silc_socket_host_lookup_start now wakes up the scheduler
4366 after adding the timeout task. Affected file is
4367 lib/silcutil/silcsockconn.c.
4369 * The silc_socket_host_lookup is synchronous now if the threads
4370 support is not compiled in. However, the callback is still
4371 called asyncronously through the scheduler, anyway. Affected
4372 file lib/silcutil/silcsockconn.c.
4374 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Added new function silc_socket_host_lookup to perform
4377 asynchronous IP and FQDN lookups for the socket connection.
4378 Affected files lib/silcutil/silcsockconn.[ch].
4380 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4383 that may or may not compile the mutex support in.
4385 Changed the silc_mutex_alloc interface. It allocates the
4386 mutex now to the sent pointer and returns TRUE or FALSE.
4388 Affected file lib/silcutil/silcmutex.h.
4390 * Wrote the SILC Task Queue interface to support multi-threads.
4391 Affected file lib/silcutil/silctask.[ch].
4393 * Wrote the SILC Scheduler to support multi-threads. Affected
4394 file lib/silcutil/silcschedule.c.
4396 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4398 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4399 in lib/silcutil/win32/.
4401 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4403 * Defined SILC Mutex API and SILC Thread API and implemented
4404 them for Unix. Affected files are
4405 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4406 lib/silcutil/unix/silcunixmutex.c and
4407 lib/silcutil/unix/silcunixthread.c.
4409 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4411 * Fixed the silc_server_remove_clients_by_server's channel
4412 key re-generation. The hash table handling was incorrect
4413 and would not work with many channels. Affected file is
4416 * Fixed some memory leaks around the server code.
4418 * Rewrote the silc_server_get_users_on_channel to support IPv6
4419 based Client ID's. Affected file silcd/server.c.
4421 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4422 specification. However, a separate document must be written
4423 to define the detailed signing procedure and the payload
4424 associated with the flag. Defined the flag to the
4425 lib/silccore/silcchannel.h as well.
4427 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4429 * Changed the dynamic tables to static size tables in the
4430 lib/silccrypt/silchmac.c.
4432 * Removed GCC dependencies from the code. A patch by cras.
4434 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4436 * Do not show the error "Error receiving packet bla bla"
4437 in server if it really was not an error (-2 means that reading
4438 is pending). Affected file silcd/server.c.
4440 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4442 * Fixed a possible crash in silc_server_remove_clients_by_server
4443 in silcd/server.c. Fixed there also some memory leaks.
4445 * Fixed the silc_idlist_replace_client_id. It could replace
4446 wrong key in the hash table. Affected file silcd/idlist.c.
4448 * Do not check whether there are global users on the channel
4449 if the channel->global_users is FALSE. Affected functions
4450 silc_server_remove_from_one_channel and
4451 silc_server_remove_from_channels in silcd/server.c. Also,
4452 do not check if the removed client is local as we can be
4453 sure that global client was not removed from the channel
4454 and checking for global users is not needed.
4456 * The silc_server_remove_clients_by_server now re-generates
4457 the channel keys correctly for those channels that had
4458 clients removed from them. Affected file silcd/server.c.
4460 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4462 * Found the reason of random crashes in the server. We weren't
4463 ignoring the SIGPIPE signal (which can be sent in write())
4464 and it crashed the server. Affected file silcd/silcd.c.
4466 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4468 * Assure that sock->user_data is not NULL in the function
4469 silc_server_packet_send in silcd/packet_send.c.
4471 * Disconnect the remote connection if it could not be added
4472 to any ID lists in the server. The affected file is
4475 * Check in silc_server_packet_send[_real/dest] that the
4476 socket is not disconnecting and ignore the data if it is.
4477 Affected file silcd/packet_send.c.
4479 * Define inline to __inline on native WIN32 compilation.
4480 Affected file includes/silcwin32.h.
4482 * Added some explicit type casts for inline code since MSVC
4483 require them. Affected files lib/silcutil/silcbuffer.h,
4484 lib/trq/silcdlist.h and lib/trq/silclist.h.
4486 * Print warning in log files from now on if the packet
4487 decryption fails. Affected file silcd/server.c.
4489 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4491 * Changed the `say' client operation's interface to accept
4492 new `type' argument to indicate the type of the message sent
4493 by the library. The application may filter the library's
4494 messages according the type. The affected file is the
4495 lib/silcclient/silcapi.h.
4497 * Added two new functions to lib/silcclient/silcapi.h:
4498 silc_client_del_client and silc_client_del_client_by_id.
4499 Affected file lib/silcclient/idlist.c.
4501 * Moved the clientincludes.h from includes/ to silc/ and
4502 serverincludes.h from includes/ to silcd/.
4504 * The modes for the CMODE and CUMODE are now passed as
4505 uint32 for application with COMMAND_REPLY. The affected
4506 file is lib/silcclient/command_reply.c.
4508 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4510 * /WHOIS without arguments shows client's own information.
4511 Affected file lib/silcclient/command.c.
4513 * Changed PING to not accept any arguments. The specs
4514 says that client can ping only the connected server so
4515 requiring an argument is not needed. Affected file is
4516 lib/silcclient/command.c.
4518 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4520 * Fixed a fatal bug in private message sending and reception
4521 encryption and decryption when using private message keys.
4522 The implementation was incorrect and did not follow the
4523 specification. It causd that some of the message were
4524 lost since it did not use the sending and receiving keys
4525 as the protocol suggests. This has been fixed and will cause
4526 incompatibilities with older clients when sending private
4527 message encrypted with private message keys. Affected files
4528 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4529 and various other in Irssi SILC Client.
4531 Added `responder' boolean argument to the functions
4532 silc_client_add_private_message_key[_ske] to indicate when
4533 the key is added as responder or initiator of the key
4536 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4538 * Removed the silc_ske_check_version function and created
4539 a SilcSKECheckVersion callback. Added also a function
4540 silc_ske_set_callbacks that is now used to set all SKE
4541 callbacks. The callback functions are not given to
4542 the SKE functions anymore, but this function is used to
4545 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4547 * Added `silc_version' argument to the silc_client_alloc
4548 to define the version of the application for the library.
4549 The library will use the version string to compare it
4550 against the remote host's (usually a server) version
4551 string. Affected file lib/silcclient/silcapi.h
4553 * Added the KE protocol context to Key Agreement context
4554 in client library so that we can abort the SKE if it
4555 is in process when we get timeout. Affected file is
4556 lib/silcclient/client_keyagr.c.
4558 * Do not resolve the client ID forever if it returns in the
4559 first time that such client does not exist. This was done
4560 for example with private message. Affected file is
4561 lib/silcclient/client_prvmsg.c.
4563 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4565 * Do not add regex.h for WIN32. The affected file
4566 includes/silcincludes.h.
4568 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4569 not work yet 100%. It generates the DLL's automatically
4570 when compiling with --with-win32 under cygwin.
4572 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4574 * lib/contrib/regex.c is not compiled on WIN32.
4576 * Added silc_net_get_socket_opt function to the
4577 lib/silcutil/silcnet.h.
4579 * Added includes/silcwin32.h for WIN32 specific includes
4582 * Do not use ptime structure or any of the posix process
4583 functions on WIN32 in lib/silccrypt/silrng.c.
4585 * Added silc_gettimeofday to provide generic function
4586 for struct timeval on all platforms. Added the function
4587 to lib/silcutil/silcutil.h.
4589 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4591 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4592 library as they clearly belong there. As a plus side we
4593 can make the actual socket connection routines platform
4596 Added also new generic function silc_socket_read and
4597 silc_socket_write (that used to be silc_packet_[read/write].
4598 The implementation of these are platform specific.
4600 * Added WIN32 specific routines of silc_socket_[read/write]
4601 to lib/silcutil/win32/silcwin32sockconn.c.
4603 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4605 * Added preliminary support for native WIN32 compilation under
4606 cygwin (using the -mno-cygwin option for GCC) to the
4607 ./configure.in.pre. The --with-win32 now prepares the
4608 compilation for native WIN32.
4610 * Rewrote the SILC Scheduler interface in the file
4611 lib/silcutil/silcschedule.h. The scheduler is now context
4612 based and does not have anymore any global static scheduler.
4613 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4614 and created lib/silcutil/win32 directory for WIN32 based
4617 * Added Unix specific network routines to the
4618 lib/silcutil/unix/silcunixnet.c and the old
4619 lib/silcutil/silcnet.c includes now only generic routines.
4621 Added WIN32 specific network routines to the
4622 lib/silcutil/win32/silcwin32net.c.
4624 * Added Unix specific utility functions from the
4625 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4627 * Added WIN32 SILC Scheduler to the file
4628 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4631 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4633 * Do not handle JOIN notify in the server if the target client
4634 is not registered (idata->registered == FALSE). The affected
4635 file is silcd/packet_receive.c.
4637 * Update the nickrec->founder in event_cumode in the Irssi SILC
4638 client. Affected file irssi/src/silc/core/silc-channels.c.
4640 * Fixed the CUMODE_CHANGE notify handling in the server when
4641 server and router are announcing their clients on channels.
4642 Now the mode changes are saved and notified correctly. The
4643 affected file is /silcd/packet_receive.c.
4645 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4646 They really did not replace the cache entry in the ID Cache.
4647 Now they do that. Affected file silcd/idlist.c.
4649 * Fixed the KICK notify handling in the Irssi SILC client to
4650 update the channel records so that the kicked client does not
4651 appear to be on the channel. The affected file is
4652 irssi/src/silc/core/silc-channels.c.
4654 * Always update the conn->current_channel when executing command
4655 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4657 * Fixed the KILL notify handling in Irssi SILC client to remove
4658 the killed client on all channels.
4660 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Fixed the silc_parse_command_line to remove extra spaces
4663 from the start and end of the arguments. Affected file is
4664 lib/silcutil/silcutil.c.
4666 * Cancel and free any active protocol in the function
4667 silc_server_close_connection. Affected file silcd/server.c.
4669 * Cancel and free any active protocol in the function
4670 silc_client_close_connction. Affected file is
4671 lib/silcclient/client.c.
4673 * Do not execute the KILL command for clients that are in
4674 history (ie. they are not in the network). Affected file is
4677 * Fixed KILL notify handling, client does not crash anymore.
4678 Affected file irssi/src/silc/core/silc-channels.c.
4680 * Reduced the default packet buffer size from 2048 to 1024 in
4681 lib/silccore/silcpacket.c.
4683 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4684 counter to the SKE context that is incresed when the SKE library
4685 performs async operation outside the library. If the outside
4686 process frees the SKE context and FREED status will be set
4687 and the library will detect after the sync operation that the
4688 libary is freed. The affected files are
4689 lib/silcske/silcske[_status].[ch].
4691 * Resolve the client entry information in the function
4692 silc_client_channel_message to assure that NULL pointer is not
4693 passed as client entry to the application. */
4695 * Fixed the task timeout calculation to assure that there is
4696 never negative timeouts. The affected file is
4697 lib/silcutil/silcschedule.c.
4699 * Fixed the channel user mode notification sending in server.
4700 It was sent point-to-point to the router (or to server by router)
4701 but it needs to be destined to a channel. The routines now
4702 supports sending the channel user mode notifys to the channels
4703 when announcing clients and channels. Affected files are
4704 silcd/server.c and silcd/packet_receive.c.
4706 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4707 It did not actually replace the old channel entry in the cache.
4708 Affected file lib/silcclient/client_notify.c.
4710 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed a possible crash in silc_packet_send_prepare. It now
4713 assures always that there is enough space in the buffer and
4714 at the tail area of the buffer (for MAC).
4716 Fixed the inbound buffer reallocation in silc_packet_read.
4717 It was old code and did not handle the reallocation correctly.
4720 The affected file is lib/silccore/silcpacket.c.
4722 * Fixed buffer overflow in silc_parse_nickname in the file
4723 lib/silcutil/silcutil.c.
4725 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * make install generates new server keys only if there is not
4730 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4733 Added check that if the NOREPLY is set then we will not send
4734 the away message. This avoids infinite loop of away messages
4735 if both clients are away. The affected file is
4736 lib/silcclient/client_prvmsg.c.
4738 * Fixed client crash if /NICK was given without arguments.
4739 Affected file lib/silcclient/command.c.
4741 * Server does not send the invite list in INVITE command back
4742 to the client if the list was not altered. Added this notion
4743 to the protocol spec as well. Affected file silcd/command.c.
4745 Fixed possible crash in INVITE command by checking the
4746 value of silc_server_get_client_route command.
4748 * Fixed the INVITE notify type handling. The arguments are now
4749 taken in correct order and client does not crash. The affected
4750 file is irssi/src/silc/core/silc-channels.c.
4752 Removed the "Inviting xxx to channel" message from the
4753 client library away and let the application handle it.
4754 Affected file lib/silcclient/command.c. Added that message
4755 to Irssi SILC client's message formats.
4757 * Fixed CMODE command crash in client. It now checks the
4758 amount of arguments correctly and does not crash. The affected
4759 file is lib/silcclient/command.c.
4761 * Do not create new channel automatically in silc_channels_join
4762 but check whether the channel by that name already exists.
4763 Affected file irssi/silc/core/silc-channels.c.
4765 * Do not send the SERVER_SIGNOFF to router if the disconnected
4766 entity was the router. Affected file silcd/server.c.
4768 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4769 SILC client as it was missing from there.
4771 Added the handling of the KICK notify to the Irssi SILC client
4772 as it was missing. Added "you have been kicked" message to
4773 Irssi SILC client's message modules formats.
4775 Added the handing of the KILL notify to the Irssi SILC client
4776 as it was missing. Added the kill message module formats
4779 The affected file is irssi/src/silc/core/silc-channels.c.
4781 * The router did not save the channel mode the server announced.
4782 Affected file silcd/packet_receive.c.
4784 * Fixed a possible crash in INFO command in server. If the
4785 server did not provide the server info it crashed. Affected
4786 file silcd/command.c.
4788 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Fixed the GETKEY command in the server to check also the
4791 global list. Otherwise the GETKEY would not work correctly
4792 in normal SILC server. Affected file silcd/command.c.
4794 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Fixed GETKEY crash, it crashed if the command did not succseed.
4798 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4801 is now real and not just an macro interface to GMP.
4803 Removed the entire GMP from the source tree and imported new
4804 NSS MPI library instead. Reason for removing GMP is that it is
4805 extremely large and compiles extremely slow. The NSS MPI
4806 is only a few files and compiles in less than 10 seconds.
4807 The speed is also about the same as GMP. The MPI is imported
4808 to lib/silcmath/mpi.
4810 If the system has GMP installed we will still use the GMP.
4811 If it is not then the NSS MPI will be compiled.
4813 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Merged a long nickname (127 characters long) crash bugfix from
4816 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4818 * Merged a freed memory reference bugfix from Irssi CVS tree.
4819 Affected file irssi/src/core/commands.c.
4821 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added the server's public key sving and verification to the
4824 server when performing the SKE. This was missing and the
4825 remote server's (or router's) public key was accepted without
4826 checking whether we have it previously or trust it at all.
4827 Affected file silcd/protocol.c.
4829 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Check in the silc_server_timeout_remote if protocol is active
4832 and make sure that the protocol's final callback is called so
4833 that all memory if freed. Affected file silcd/server.c.
4835 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * silc_server_whois_send_reply crashed the server if the nickname
4838 was 127 characters long. Affected file silcd/command.c.
4840 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Added sanity check to the silc_server_new_client. If the hostname
4843 is provided inside username then check that the provided hostname
4844 really is the same as the resolved one. If the hostname was not
4845 resolved then check it from the public key. Affected file is
4846 silcd/packet_receive.c.
4848 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4849 if the server disconnected us and the connection is not valid
4850 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4852 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4853 the library to the lib/silcutil/silcutil.[ch].
4855 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Close log file after open. Affected file
4858 lib/silcutil/silclog.c.
4860 * Check whether sock == NULL in silc_client_send_packet and return
4861 if it is. Affected file lib/silcclient/silcclient.c.
4863 * Check rec->entry == NULL in the Irssi SILC Client before
4864 sending the channel message. Affecte file is
4865 irssi/src/silc/core/silc-servers.c.
4867 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Merged a splitted window bugfix from Irssi CVS tree. The
4870 affected file is irssi/src/fe-text/textbuffer-view.c.
4872 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4873 It did not print nickname.
4875 * Improved the distributions system a bit.
4877 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4880 irssi/src/fe-text/gui-window.c.
4882 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4883 to in-active server. The affected file is
4884 irssi/src/silc/core/client_ops.c.
4886 * Resolve the client in USERS command reply if the entry does
4887 not have username resolved. The affected file is
4888 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4889 command to WHOIS command to really resolve stuff. The USERS
4890 is not used any more in any critical section so WHOIS can
4891 be used even though it might be slower than IDENTIFY.
4893 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4896 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Changed the protocol API a bit more consistent in the
4899 lib/silccore/silcprotocol.[ch].
4901 * Changed the following headers to ROBODoc format:
4903 lib/silccore/silcpayload.h
4904 lib/silccore/silcprotocol.h
4905 lib/silccore/silcsockconn.h
4907 All core library headers are now formatted.
4909 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Fixed a bug in Irssi SILC client; do not show that you are
4912 server/router operator if you really are not. Affected file is
4913 irssi/src/silc/core/client_ops.c.
4915 * Renamed silc_command_free_payload to silc_command_payload_free.
4916 Affected file lib/silccore/silccommand.h
4918 * Added silcmath.h to include the prototoypes of various routines
4919 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4922 * Changed the following headers to ROBODoc format:
4924 lib/silccore/silcchannel.h
4925 lib/silccore/silccommand.h
4926 lib/silccore/silcid.h
4927 lib/silccore/silcidcache.h
4928 lib/silccore/silcmode.h
4929 lib/silccore/silcnotify.h
4930 lib/silccore/silcpacket.h
4931 lib/silcmath/silcmath.h
4933 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added checking to the server code not to start the server if
4936 ciphers and stuff are not configured properly. Affected files
4937 silcd/serverconfig.[h] and silcd/server.c.
4939 * Changed the layout of the header files of the public interfaces
4940 in the SILC libraries. The new layout supports ROBODoc
4941 documentation tool (and some others) so that it is easy to create
4942 a library reference manual. All the other headers and source
4943 code must still follow the CodingStyle document. Also source
4944 code must not include these ROBODoc stuffs, only the headers.
4945 Furthermore, all public interface headers must now be named
4946 by using `silc' prefix, example: silcapi.h, silccipher.h.
4947 Some files were renamed due to this. All the other headers
4948 must not be used as public interfaces. I will update the
4949 CodingStyle document later. Changed following headers, so far:
4951 lib/silcclient/silcapi.h
4952 lib/silccore/silcauth.h
4953 lib/silccore/silcprivate.h
4954 lib/silccrypt/silcdh.h
4956 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Removed silc_client_packet_send_flush from the client library
4961 as it is not needed. Affected file lib/silcclient/client.[ch].
4963 * Added printing of message of unresolved authentication method
4964 to the Irssi SILC client. Added it to the module formats.
4965 Removed the same message from the client library.
4967 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Added new distribution feature, DISTLABEL. Every distribution
4970 can define own preprocessor label that can be used in the
4971 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4972 file distributions, acconfig.h.pre and prepare.
4974 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added Makefile.defines_int to include the actual definitions
4977 for Makefile.defines.in. Tested the new distribution system,
4978 created distributions and tested installation.
4980 * Added AWAY message printing to the Irssi SILC client. Added
4981 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4983 * Added SCONNECT command to call the SILC's CONNECT command.
4984 Cannot use CONNECT directly since Irssi uses that internally.
4985 Affected file irssi/src/silc/core/silc-servers.c.
4987 Added ACTION local command. It is same as ME command but takes
4988 the channel as mandatory argument.
4990 Rewrote some of the Irssi's help files to suite for SILC
4993 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added Makefile.defines[.in] that should for now on be included
4996 in all Makefile.am file in the source tree. That file includes
4997 all common compilation definitions for SILC source tree.
4999 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Minor changes to the ./prepare script to change the package
5002 name according the distribution name to the configure.in.
5004 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Created new distribution system. Added file `distributions'
5007 that defines all the distributions that can be created out of
5008 the SILC source tree. The ./prepare script now reads that
5009 file to determine how to prepare the distributions. The
5010 first argument to the ./prepare is the name of the distribution
5011 and second is the version of the distribution. If given
5012 without arguments it creates the default (toolkit) distribution
5013 with the default version (defined in ./prepare).
5015 All Makefile.am files that are subject to the distributions
5016 are now named as Makefile.am.pre. These are ./Makefile.am
5017 and lib/Makefile.am. Others may be changed later.
5019 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Added invite list, ban list, some key management and connection
5022 error message printing to module formats in the Irssi SILC client.
5024 * Added new silc_client_set_away_message to set the away message
5025 that is back to the person who sent private message. The
5026 affected file lib/silcclient/silcapi.h and the
5027 lib/silcclient/client_prvmsg.c.
5029 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Fixed the private message sending in the Irssi SILC client,
5032 added local command KEY to the Irssi SILC client.
5034 Added key management and key agreement message formats to the
5035 irssi/src/fe-common/silc/module-formats.[ch].
5037 Added USERS (alias WHO) printing, server/router operator
5038 indication and LIST command printing to the module formats.
5040 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Fixed channel joining notify handling, cumode notify handling
5043 from Irssi SILC client.
5045 * Added SILC specific module-formats to the Irssi SILC client so
5046 that SILC specific message hilighting, colors etc is possible.
5047 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5049 Added channel mode, channel user mode, actions, notices,
5050 whois and whowas printing to the the module-formats.c.
5052 * Fixed a bug in channel deletion in the server. The channel
5053 is not left to the cache even if the channel founder auth mode
5054 is set when there are no users anymore on the channel. Affected
5055 file silcd/server.c.
5057 * The silc_net_localhost now resolves the entire hostname including
5058 the domain name. Affected file lib/silcutil/silcnet.c.
5060 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Changed the ask_passphrase client operation to be ascynchronous.
5063 It has now a completion callback and a context that the
5064 application must call after it has got the passphrase from
5065 the user. Affected files lib/silcclient/silcapi.h,
5066 lib/silcclient/protocol.c, lib/silcclient/command.c and
5069 Added SilcAskPassphrase callback that the application calls
5070 to deliver the passphrase to the library.
5072 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5073 The public key verification and especially a certificate
5074 verification is asynchronous procedure.
5076 Added new SILC_SKE_STATUS_PENDING status to indicate the
5077 request is pending and a callback will be called to finalize
5080 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5081 indicate that remote end did not send its public key (or
5082 certificate), even though we require it. Added check for this
5083 condition in the SKE. This was a security bug, now fixed.
5085 Defined new SilcSKEVerifyCbCompletion callback that is called
5086 when the verification process is completed.
5088 The affected files lib/silcske/silcske_status.h and
5089 lib/silcske/silcske.[ch].
5091 * Changed the verify_public_key client operation to be async
5092 as well. Defined SilcVerifyPublicKey callback that is used to
5093 indicate the success of the public key verification process.
5095 Changed the server and client to use the new async client
5098 * Changed the Irssi SILC client's internal scheduler to be called
5099 twice as many times as it used to be. As a result the client
5100 should be a bit faster now. Affected file is
5101 irssi/src/silc/core/silc-core.c.
5103 * Added support to Irssi SILC client of asynchronous public key
5104 verification and passphrase inquiry. Affected file is
5105 irssi/src/silc/core/silc-core.c.
5107 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Do not say "You have left channel %s" in client library.
5110 Moved it to the application. Affected files are
5111 lib/silcclient/command.c and silc/client_ops.c.
5113 * Fixed silc_client_get_clients. Command context was not
5114 duplicated and was freed memory in the callback. Affected
5115 file lib/silcclient/idlist.c.
5117 * Do not say "you are now talking..." on JOIN command in the
5118 client library. The appliation must handle it.
5120 * Do not say ".. changed topic to" in command reply in the
5121 client libary. The application must handle it.
5123 * Fixed TOPIC command sending in the client library.
5125 * Fixed a memory leak in silc_client_command_free in the file
5126 lib/silcclient/command.c.
5128 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Imported a modified version of Irssi client to the source tree.
5131 The Irssi will be used to create a new client called
5132 Irssi SILC. Imported to irssi/.
5134 Added silc_core_init_finish function to the Irssi. Affected
5135 file irssi/configure.in.
5137 A lot changes in the Makefile.ams around the irssi tree.
5139 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Do not rehash if the new size is same as the old size of the
5142 hash table, in the silc_hash_table_rehash*. The affected file
5143 lib/silcutil/silchashtable.c.
5145 * Replaced hash_table_del_by_context calls from the server
5146 (when channel->user_list and client->channels) to the
5147 hash_table_del as it is sufficient and faster.
5149 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Added silc_hash_table_list, silc_hash_table_get and the
5152 SilcHashTableList structure to provide an alternative way to
5153 traverse the hash table. The affected files are
5154 lib/silcutil/silchashtable.[ch].
5156 * Changed the server's idlist routines to use the hash table
5157 routines to optimize the code.
5159 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Replaced the client entry's `channel' list and channel entry's
5162 `user_list' list to hash tables for optimized lookup. Changed
5163 the code to use the hash table interface around the code.
5164 Affected file lib/silcd/idlist.[ch].
5166 * Added `auto_rehash' boolean argument to the function
5167 silc_hash_table_alloc to indicate whether the hash table should
5168 auto-rehash when it thinks is appropriate time. It will
5169 increase the hash table size if the there is twice as much
5170 entries in the table than the size of the table, and will
5171 decrease the size if there are twice as less entries than
5172 the size of the table.
5174 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5178 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * silc_idcache_purge_by_context deletes the entry now by context
5181 as it is supposed to do. Affected file lib/silccore/idcache.c.
5183 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5184 client is not anymore valid (WHOWAS givens the info) and not
5185 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5187 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Removed the `data' and `data_len' arguments from the ID Cache
5190 interfaces and added `name' argument. ID Cache does not handle
5191 anymore the binary data only a names associated with given ID.
5193 * When hashing a Client ID with silc_hash_id the entire ID is
5194 not hashed anymore, instead only the hash of the Client ID is
5195 hashed. This way we can access the Client ID from the cache
5196 with Client ID but with the hash of the ID (which is a hash of
5197 the nickname) as well without any difference in performance.
5199 Added also silc_idcache_find_by_id_one_ext to do one on one
5200 searching when we have the actual ID. Added also function
5201 silc_hash_client_id_compare. The affected files are
5202 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5204 * When hashing the name associated with a ID it is always done
5205 in lowercase. This way we can access the cache without worrying
5206 about case-sensitivity, even though, for example nicknames are
5209 * Fixed a bug in server with channel message sending. It put
5210 wrong ID type as destination ID. The affected file
5211 silcd/packet_send.c.
5213 * silc_idcache_del_by_context now deletes from all hash tables
5214 by context. Affected file lib/silccore/idcache.c.
5216 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Changed the client library to use the new ID Cache interface.
5219 Changes around the source tree.
5221 * Added silc_hash_table_rehash_ext to rehash with specific
5222 hash function. Affected file lib/silcutil/silchashtable.[ch].
5224 * Added silc_hash_string_compare to compare two strings in the
5225 hash table. Affected file lib/silcutil/silcutil.[ch].
5227 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added new function silc_idcache_del_by_context into the
5230 lib/silccore/idcache.[ch].
5232 * Changed the server's ID list routines to use the new ID Cache
5233 interface. Changes around the source tree.
5235 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added silc_hash_table_del[_by_context]_ext functions in to the
5238 lib/silcutil/silchashtable.[ch].
5240 Removed silc_hash_table_find_all* routines and added new
5241 silc_hash_table_find_foreach to replace them.
5243 Added silc_hash_table_replace_ext function as extended
5244 replacing function. Separated the simple hash table interface
5245 from the extended hash table interface in the file
5246 lib/silcutil/silchashtable.h.
5248 * Fixed minor bugs and changed it to use some of the new
5249 hash table functions in lib/silccore/idcache.c
5251 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Added new function silc_hash_table_find_all to return all keys
5254 in the hash table by the specified key. As the hash table is
5255 collision resistant it also makes it possible to have several
5256 duplicate keys in the hash table. This function may be used to
5257 find all of the keys from the hash.
5259 Added user_context arguments to the SilcHashFunction,
5260 SilcHashCompare and SilcHashDestructor to deliver user specified
5263 Added new fuctions silc_hash_table_find[_all]_ext to do
5264 extended lookup with specified hash and compare functions and
5265 specified user contexts.
5267 Added new function silc_hash_table_add_ext to add the key
5268 with specified hash function and user context.
5270 Added new function silc_hash_table_foreach to traverse all
5271 entrys in the hash table. Added SilcHashForeach callback
5274 Added new function silc_hash_table_del_by_context to delete
5275 the entry only if the context associated with the key matches.
5277 Affected files are lib/silcutil/silchashtable.[ch].
5279 * Removed silc_hash_[server/client/channel]_id and added just
5280 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5281 silc_hash_id_compare to compare two ID's using as the hash table
5282 comparison function. Added also silc_hash_data to hash
5283 binary data and silc_hash_data_compare to compare it.
5285 * Removed silc_idlist_find_client_by_hash as it is not needed
5286 anymore. Affected file silcd/idlist.[ch].
5288 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5289 to use internally the SilcHashTable. The new ID Cache is a lot
5290 faster than the old one. Some of the ID Cache interface was also
5291 rewritten and obsolete and stupid functions were removed.
5293 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added entry_count field to the SilcHashTable to keep the number
5296 of the entries in the table. Implemented the function
5297 silc_hash_table_rehash. Added new function
5298 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5300 Fixed a minor bug in silc_hash_table_free.
5302 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5303 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5304 into the lib/silcutil/silcutil.[ch].
5306 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Implemented a collision resistant hash table into the
5309 lib/silcutil/silchashtable[ch]. See the header and the source
5310 for the SilcHashTable API.
5312 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Merged dotconf version 1.0.2 into lib/dotconf.
5316 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Do not compile anything in lib/silcsim/* if the SIM support
5319 is not enabled. The tree should now compile without problems
5322 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Compiled the SILC under cygwin. Compiled and tested briefly
5325 without problems. More tests needed. The SIMs didn't compile
5328 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5330 * Fixed possible crash in silc_get_username in the
5331 lib/silcutil/silcutil.c.
5333 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Fixed a va_arg in silc/client_ops.c.
5337 * Oops, RC5 routines were named AES and caused some problems
5338 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5340 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Added new SilcIDIP structure into the lib/silccore/id.h and
5343 replaced the old `ip' fields from all SILC ID's to that type.
5344 This is a step towards IPv6 support.
5346 The silc_id_get_len takes now the ID as an extra argument.
5347 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5348 both IPv4 and IPv6 based ID's.
5350 The affected files are lib/silccore/id.[ch] and other files
5351 around the tree using these routines.
5353 * Removed the ID length arguments in server from various
5354 silc_server_send_notify_* routines -> they are not needed
5357 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Fixed memory leak in silc_encode_pem_file in the file
5360 lib/silcutil/silcutil.c.
5362 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Check minor version as well in the SKE. Affected files are
5365 silcd/protocol.c and lib/silcclient/protocol.c.
5367 * Added --identifier option to the server so that an identifier
5368 can be when creating the public key for the server. Affected
5369 file is silcd/silcd.c.
5371 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5372 lib/silccrypt/silcpkcs.c.
5374 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Register default ciphers and stuff when using -C option with
5377 the server. Affected file sildc/silcd.c.
5379 * Put back the servers public key filename format, it is better
5380 than the new one. For now, the client keys are saved with the
5381 new filename format. The affected file silc/client_ops.c.
5383 * Implemented the Cipher API for the rest of the ciphers that
5384 did not implement it or implemented it the wrong way.
5386 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Register default ciphers and stuff when using the -S option
5389 in the client. Affected file silc/silc.c. Same also when
5390 creating new key pair with -C option.
5392 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed the silc_verify_public_key client operation function to
5395 save the public keys differently. The fingerprint is now
5396 used as filename and not the hostname. This way also the
5397 client keys are saved uniquely and not with hostnames. The
5398 affected file is silc/client_ops.c.
5400 * Trimmed the silc_hash_fingerprint function to remove extra
5401 whitespaces from the end of the fingerprint. The affected
5402 file is lib/silccrypt/silchash.c.
5406 * Added silc_cipher_register_default function to register all
5407 default ciphers. It can be used when configuration files
5408 does not exist and the application does not want any specific
5409 ciphers in any specific order.
5411 The SilcDList is now used as silc_cipher_list dynamically
5412 allocated cipher list. Removed the static list all together
5413 and now all ciphers must be allocated to the dynamic list.
5414 The silc_cipher_alloc routine was changed to check only the
5417 All silc_cipher_* routines that used to return int returns
5420 The affected files lib/silccrypt/silccrypt.[ch].
5422 * The same thing was done to silc_hash_* as for silc_cipher_*
5423 routines. Affected files lib/silccrypt/silchash.[ch].
5425 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5426 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5427 Added also silc_pkcs_[un]register[_default] functions.
5428 Removed the data_context from the PKCS API.
5430 * Added silc_hmac_register_default function to register default
5431 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5432 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5433 to unregister all hmacs at once.
5435 * Register the default ciphers, hash functions, PKCSs and HMACs
5436 if client's configuration file does not exist. The affected
5439 * The client did not load the hash functions from the SIM
5440 modules at all. Added support for this. Affected file is
5441 silc/clientconfig.c.
5443 * When decoding public key with silc_pkcs_public_key_decode, check
5444 the supported algorithm only if PKCS are registered. Affected
5445 file lib/silccrypt/silcpkcs.c. The same was done with the
5446 silc_pkcs_private_key_decode.
5448 * Fixed the SILC List routines to keep the list always in order.
5449 It used to change the list's order when traversing the list but
5450 not it preserves the order. Affected file lib/trq/silclist.h.
5452 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added the client library to use the SilcSocketConnection's
5455 reference counter (by silc_socket_dup) to prevent the bug that
5456 the socket object may be freed underneath async operation.
5458 * The name resolv library checking fixes in the configure.in.pre.
5461 * Created new version of the protocol drafts for future
5462 development. The -03 drafts are the ones that will be changed
5463 in the trunk now and the -02 will remain as they are.
5465 * Send list of CUMODE notifys to the router when announcing
5466 the channel users to the router. Affected file silcd/server.c.
5467 If the router receiving channel founder CUMODE for a channel
5468 that already has channel founder it will send CUMODE notify
5469 to the sender to remove the channel founder rights from the
5470 announced client. Affected file silcd/packet_receive.c.
5472 * The CUMODE notify may now use Server ID as well as the entity
5473 who changes the mode. Updated protocool specs.
5475 * Updated INSTALL and README files.
5477 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * New web pages in the http://silc.pspt.fi. The pages was
5484 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Implemented the [DenyConnectin] config section in the server.
5487 Added silc_server_config_denied_conn to check whether incoming
5488 connection is denied. Affected file silcd/serverconfig.[ch].
5490 * Do not check the ports when checking the incoming configuration
5491 data if the port is 0, meaning any. Affected file is
5492 silcd/serverconfig.c.
5494 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Fixed buffer overflow in silc_string_compare in the file
5497 lib/silcutil/silcutil.c.
5499 * Fixed double free in silc_server_command_leave in the file
5502 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Fixed the version checking in the server. Affected file is
5507 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Fixed the configuration data fetching when accepting new
5510 connections in the server. Affected file silcd/server.c.
5512 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Added `sender_entry' argument to the function
5515 silc_server_packet_relay_to_channel so that we can check
5516 whether some destination actually belongs to the same route
5517 the sender belongs (ie, we must not resend the packet to the
5518 sender). Affected file silcd/packet_send.[ch].
5520 * Added `servername' field to the SilcClientEntry in the server
5521 to hold the name of the server where client is from. Affected
5522 file is silcd/idlist.h.
5524 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Moved the channel message encrypting in the router betwen
5527 router connections from silc_server_channel_message to the
5528 silc_server_packet_relay_to_channel since we want to check
5529 whether we have anybody channel before encrypting anything.
5530 Affected files silcd/packet_[receive/send].c.
5532 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Fixed the [AdminConnection] server config section to support
5535 multiple entries. Affected file silcd/serverconfig.c.
5537 * Added support into the server to check the validity of the
5538 incoming connection before executing any KE or authentication
5541 * The connection configuration is now saved to the KE and
5542 connection auth protocol contexts and not fetched anymore in
5543 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5545 * The local hosts listenning address and port is also resolved
5546 now when starting the server. We want to have the socket object
5547 to include the real address and port for the listener. Added
5548 new function silc_net_check_local_by_sock into the files
5549 lib/silcutil/silcnet.[ch].
5551 * Fixed a broadcast bug in server -> do not broadcast if we
5554 * Fixed a routing bug. Do not route broadcast packets ever.
5555 Broadcast packets must be processed always and not routed since
5556 they may be destined to some other host than yourself and thus
5557 would get routed without no good reason. Affected file is
5560 * Added function silc_server_config_is_primary_route to check
5561 whether primary router connection has been configured (a router
5562 configuration that we are initiating). If there is not, we
5563 will assume that there is only two routers in the SILC network
5564 and we will use the incoming router connection as our primary
5565 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5567 * Changed the order of the broadcasting. Broadcast _after_ the
5568 packet has been processed not before. Affected file is
5571 * Fixed a [ClientConnection] parsing bug. The port was never
5572 parsed correctly thus resulting to port 0. Affected file
5573 silcd/serverconfig.c.
5575 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5576 argument and did not set the broadcast packet flag. Affected
5577 file silcd/packet_send.c. Fixed same bug in the function
5578 silc_server_send_notify as well.
5580 * If we receive NEW_ID packet for our own ID in the server, ignore
5583 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Removed the nickname from the Private Message Payload.
5588 Updated the code and the protocol specs.
5590 * Updated protocol specs for submitting to the IETF.
5592 * Tweaked the Random Number Generator a bit. Affected file
5593 lib/silccrypt/silcrng.c. Exported a new function
5594 silc_rng_[global]_add_noise which can be used to add more
5597 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Do not parse packets with different timeout when protocol
5600 is active -> may cause problem with rekey. Affected file
5603 * When server receives signoff notify it must not create
5604 new channel key if the client is on any channels since the
5605 sender of the signoff notify will create it.
5607 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added printing of error messages during SKE protocol from the
5610 failure packet sent by server during SKE. Affected file
5613 * Removed the client's failure_callback handling with timeout
5614 and handle it immediately when received.
5616 * The SKE library returned wrong type in SUCCESS and FAILURE
5617 packets. They must be 32 bit MSB not 16 bit MSB.
5619 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Ok, rewrote the logic of the re-key and now it seems to work.
5622 I tested it on high traffic with frequent re-keys without
5623 problems. Added hmac_receive (and renamed hmac to hmac_send)
5624 in SilcClientConnection in lib/silcclient/client.h and
5625 in SilcIDListData in silcd/idlist.h. Also, removed the
5626 SilcPacketParserContext's cipher and hmac fields as they are
5627 not needed anymore and actually caused some problems when
5628 the ciphers and hmac's changed underneath the packet parser.
5630 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * If re-key protocol is active then process the incoming packets
5633 synchronously since we must assure that icoming packets encrypted
5634 with the old key is processed before the new keys is set to
5635 use. This is true other packets than for REKEY packets.
5636 Affected file silcd/server.c. The same was done to client library
5637 as well, affected file lib/silcclient/client.c.
5639 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Fixed bug in client and server to accept the force send if
5642 the packet is send from silc_[server/client]_packet_process
5643 function. Otherwise the packets are never delivered, oops.
5645 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Disable force sending of packets when REKEY protocol is active.
5648 We must assure that no packet is sent directly when rekey is
5649 performed. All packets must be sent through packet queue.
5650 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5651 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5652 function is silc_[server/client]_packet_send_real to check
5655 * Replaced the SIM paths from example config files to
5656 /usr/local/modules. Also, make install creates now
5657 /usr/local/silc/logs directory to hold all the SILC server
5660 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Made the configure.in.pre work on Solaris. Patch by salo.
5664 * Made all ciphers compatible with non-x86 machines. Defined
5665 CBC mode macros into lib/silccrypt/ciphers_def.h.
5667 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Fixed the make install.
5671 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * When MAC computation fails the silc_packet_decrypt returned 0
5674 even though it was supposed to return -1. Fixed this. The
5675 affected file is lib/silccore/silcpacket.c.
5677 * Do not replace the config files in /etc/silc (in make install)
5678 if they already exist. Affected file ./Makefile.am.
5680 * Do not send re-key packets immediately but through packet queue.
5681 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5683 * Changed silc_net_check_host_by_sock to return FALSE if the
5684 IP/DNS could not be resolved. Though, it returns the IP address
5685 now even if it could not resolve it (but returns also FALSE).
5686 Affected file lib/silcutil/silcnet.[ch].
5688 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added silc_pkcs_decode_identifier to decode the public key's
5691 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5692 Added also silc_pkcs_free_identifier. Added also new context
5693 SilcPublicKeyIdentifier.
5695 * Added -S option to the silc client. It is used to dump the
5696 contents of the specified public key file.
5698 * Changed the PKCS api to return the public key length when
5699 setting the public key.
5701 * Fixed a fatal bug in the public and private key file loading.
5702 Affected file lib/silccrypt/silcpkcs.c.
5704 * Execute the packet parsing for client with zero (0) timeout
5705 if the protocol is active. Affected file silcd/server.c.
5707 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Made the key generation options to the silcd program. Added
5710 -C option, equivalent to client's option.
5712 * Added new [ServerKeys] config section to the server. It
5713 configures the server's public and private key.
5715 * Defined generic Public Key Payload into the protocol
5716 specification to send specific type of public keys and
5719 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5720 public key or certificate.
5722 * Implemented the GETKEY command to the server and to the
5723 client library and on user interface.
5725 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Made preliminary `make install' work.
5729 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added SilcServerRekey context into silcd/idlist.h.
5733 * Added the PFS support as defined in the specification to the
5734 SKE protocol. Affected files lib/silcske/*.c.
5736 * Added `ske_group' field to the SilcServerRekey context to hold
5737 the number of the SKE group that is used with PFS in re-key.
5738 Affected file silcd/idlist.h.
5740 * Added PFS re-key support to the server. Affected file is
5743 * Added silc_protocol_cancel to cancel execution of the next
5744 state of the protocol. Affected file is
5745 lib/silccore/silcprotocol.[ch].
5747 * Added the re-key support with and without PFS to the client
5748 library. Re-key is performed once in an hour, by default.
5750 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5751 Added silc_client_rekey_callback and silc_client_rekey_final.
5752 Affected files are lib/silcclient/protocol.[ch] and
5753 lib/silcclient/client.[ch].
5755 * Removed the `hmac_key' and `hmac_key_len' fields from the
5756 SilcClientConnection structure; not needed. Affected file is
5757 lib/silcclient/client.h.
5761 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Do not ask whether user wants to use the negotiated private key
5764 for private messages, just use it. Affected file is
5765 silc/local_command.c.
5767 * Added `send_enc_key' and `enc_key_len' fields to the
5768 SilcIDListData structure since they are needed in the re-key
5769 phase. Affected file is silcd/idlist.[ch].
5771 * Implemented the simple re-key protocol into the server.
5772 Affected files silcd/server.c and silcd/protocol.[ch]. The
5773 re-key will be performed once in an hour, by default.
5775 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5776 Added silc_server_rekey, silc_server_rekey_callback and
5777 silc_server_rekey_final.
5779 * Removed Tunneled flag from the protocol. Updated the code
5780 and the specifications.
5782 * Adde `pfs' field to the SilcIDListData to indicate whether
5783 the PFS is to be performed in the re-key. Affected file is
5786 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5789 int64 of at least the xintXX size. If void * is less that 4
5790 bytes uint32 * will be used. Defined bool as boolean.
5792 * Changed _ALL_ unsigned long and unsigned int to uint32,
5793 unsgined short to uint16 in the source tree.
5795 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5796 not handle clients that has entry->data.registered == FALSE.
5797 They are not in the network anymore. Affected file is
5800 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Implemented the sending of the SERVER_SIGNOFF notify in the
5803 server. Affected file is silcd/server.c.
5805 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5806 Added also silc_notify_payload_encode_args into the
5807 lib/silccore/silcnotify.[ch].
5809 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5810 Affected file silcd/packet_receive.c.
5812 * Implemented the SERVER_SIGNOFF notify handling in the client
5813 library. Affected file lib/silcclient/client_notify.c. Also,
5814 implemnted the printing of the SERVER_SIGNOFF info to the
5815 application. Affected file silc/client_ops.c.
5817 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5818 if the deleting was successful. Affected file silcd/idlist.[ch].
5820 * Added support for public key authentication in the connection
5821 authentication protocol in the client library. Affected file
5822 lib/silcclient/protocol.c.
5824 * Changed the server's silc_idlist_get_clients_by_* interface
5825 to support already allocated array so that new entries may be
5826 added to pre-allocated array. Affected file silcd/idlist.[ch].
5827 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5828 and command replies.
5830 * All command reply functions in the server now calls the
5831 pending command callback even if error occured. This way the
5832 error will be delivered to the client as well. Affected files
5833 silcd/command.c and silcd/command_reply.c.
5835 * Fixed INFO command to return local server's info if no server
5836 was provided. Affected file lib/silcclient/command.c.
5838 * Removed RESTART command for good. Updated the code and the
5841 * Rewrote parts of the task system. It is a bit simpler now.
5842 Removed unsued task priorities. The affected files are
5843 lib/silcutil/silctask.[ch].
5845 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Moved the USERS printing from the library to the application.
5848 Affected files lib/silcclient/command.c and silc/client_ops.c.
5850 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Added channel key re-key support. The re-key is perfomed
5855 only by the router and is done once in an hour. Added `rekey'
5856 field to the SilcChannelEntry in the server. Affected files
5857 silcd/server.c and silcd/idlist.h.
5859 * Added silc_task_unregister_by_context into the file
5860 lib/silcutil/silctask.[ch].
5862 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Added SILC_UMODE_GONE mode to indicate when the client is not
5865 present in the SILC network. Added also support to the local
5866 command AWAY that will set this mode. Added support of showing
5867 "xxx is gone" in WHOIS command. The USERS command shows the
5868 gone status as well.
5870 * Fixed setting server and router operator privileges in the
5871 server's UMODE command. Affected file silcd/command.c.
5873 * Merged the SKE KE1 and KE2 payloads into one payload. The
5874 new KE payload is equivalent to the old KE2 payload.
5876 Cleaned up the SKE Start Payload parsing. It now uses the
5877 simple buffer unformatting to do the parsing. A lot faster
5880 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5881 to the SKE that is used to indicate whether both of the SKE
5882 parties should perform authentication. By default only the
5883 responder performs authentication. By setting this flag also
5884 the initiator must do authentication. By default it is unset
5885 since in normal SKE case, client to server connection, only
5886 the responder should do authentication. When doing SKE between
5887 two clients both should perform authentication. Updated the
5888 code and the protocol specs.
5890 * A little fix to IDENTIFY command in the server. Search the
5891 client first by hash not nickname. Affected file is
5894 * Fixed the silc_client_close_connection to support closing
5895 the client to client connections wihtout deleting too much
5896 data. Affected file lib/silcclient/client.c.
5898 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5899 are received if protocol used to be active but is not anymore
5900 the application would crash due to NULL pointer dereference.
5901 Affected files silcd/server.c and lib/silcclient/client.c.
5903 * Added `hash' field to the SilcClientConnection to include
5904 the hash function negotiated in the SKE protocol.
5906 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5907 to set the channel founder authentication data. A client can
5908 claim the founder rights later by providing the authentication
5909 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5910 This way the channel founder can regain the channel founder
5911 privileges even it is left the channel. This works only on
5912 local server and the client must be connected to the same
5913 server to be able to regain the founder rights. Updated the
5914 protocol specs accordingly.
5916 Added support to the CMODE command in the client to set the
5917 founder auth data. Read the README to see how to set it.
5919 Added support to the CUMODE command to claim the founder
5920 rights. Read the README to see how to do it.
5922 Added support for the founder authentication to the Channel
5923 Entry in the server. Affected file silcd/idlist.h.
5925 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5926 server's CMODE command. Affected file silcd/command.c.
5928 * Added the following new functions into lib/silccore/silcauth.[ch]:
5929 silc_auth_get_method and silc_auth_get_data.
5931 * The server now saves the remote hosts public key to the
5932 SilcIDListData pointer. Affected file silcd/protocol.c.
5934 * The normal server now does not remove the channel entry from
5935 the cache if the founder authentication data is set. It used
5936 to remove it if the founder was the last one on the channel on
5937 the server and left the channel. The auth data is saved and
5938 if the channel is re-joined later the old entry is used with
5939 the old auth data. Affected files silcd/command_reply.c and
5942 * Removed the `pkcs' field from the SilcIDListData structure
5943 in the server; it is not used. Affected file silcd/idlist.h.
5945 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Fixed packet processing on slow links. Partial packets were
5948 never re-processed because the incoming data buffer was cleared
5949 by the application. Application must not directly clear the
5950 sock->inbuf, the packet processing routines handle it. Fixed
5951 this in client library and in server.
5953 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Fixed the WHOIS and IDENTIFY send reply function to really
5956 check whether to send list or just one entry. Affected file
5959 * Cleaned up the LEAVE command's channel key distribution. The
5960 affected file silcd/command.c.
5962 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5963 can enforce the channel mode as well. In that case the ID
5964 includes the ID of the server. The code now enforces the
5965 mode change if the router have different mode than the server.
5967 * The notify client operation with CMODE_CHANGE notify can now
5968 return NULL client_entry pointer if the CMODE was not changed
5969 by client. Application must check for this.
5971 * Added <Server ID> argument to INFO command to support server
5972 info fetching by Server ID.
5974 * Added silc_server_announce_get_channel_users to get assembled
5975 packets of channel users of the specified channel. Affected
5976 file silcd/server.[ch].
5978 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5979 was freed underneath the ID Cache.
5981 * Re-announce clients when the server received CHANNEL_CHANGE
5982 notify from the router. Affected file silcd/packet_send.c.
5984 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5987 crashed since it did not handle the fact that there is no cipher
5988 called "3" and didn't check the error condition. Now fixed.
5990 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5991 flag. It can be used to send message requests.
5993 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Implemented the RESTART command in the client.
5997 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5998 notice type messages. Added notice printing to the user
6001 * The channel keys are not re-generated if the channel's mode
6002 is PRIVKEY, ie private key on the channel exists. Affected
6003 files silcd/server.c and silcd/command.c.
6005 * Fixed a little bug in channel message delivery when channel
6006 private keys are set in the server. Affected file is
6007 silcd/packet_send.c.
6009 * Changed the setting on channel->on_channel = TRUE from the
6010 silc_client_save_channel_key to the JOIN command reply. The
6011 key payload is not received if the private channel key is set.
6012 Affected file lib/silcclient/command_reply.c and the
6013 lib/silcclient/client_channel.c.
6015 * When the CMODE_CHANGE notify is sent and the channel private
6016 key mode is removed the channel key must be re-generated in
6017 other cells as well. Added this support for the router in the
6018 silcd/packet_receive.c.
6020 * Added new local command NOTICE to send notice message on
6021 channel. Affected file silc/local_command.[ch].
6023 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added new local command ME to the client. It is used to send
6026 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6027 some action. Affected file silc/local_command.[ch].
6029 * Changed channel_message and private_message client operations
6030 to deliver the message flags to the application. Added also
6031 the `flags' arguments to the silc_client_send_channel_message
6032 and silc_client_send_private_message functions. Affected file
6035 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Redefined the Private Message Payload to support private message
6038 keys and to support the new private message flags. Updated
6039 the protocol specs. Flags makes it possible to have for example
6040 CTCP style messages.
6042 * Added new type SilcPrivateMessagePayload and defined an API
6043 for it in the lib/silcclient/silcprivate.[ch].
6045 * Tested private message private keys successfully. Tested the
6046 private message key set, unset and list commands with the new
6049 * Redefined the Channel Message Payload to include the channel
6050 message flags (equal with private message flags) to support
6051 for example CTCP style messages.
6053 * Defined some of the message (for channel and private message)
6054 flags. Updated the protocol specs and added the flags to the
6055 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6057 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added SilcKeyAgreementStatus type to the key agreement routines
6060 to indicate the current status and error if one occured.
6061 The status types are defined in the lib/silcclient/silcapi.h.
6063 * Added new local command KEY that is used to set and unset private
6064 keys for channels, set and unset private keys for private messages
6065 with remote clients and to send key agreement requests and
6066 negotiate the key agreement protocol with remote client. The
6067 key agreement is supported only to negotiate private message keys,
6068 it currently cannot be used to negotiate private keys for channels,
6069 as it is not convenient for that purpose.
6071 * Fixed a minor pending callback setting bug in the function
6072 silc_client_get_client_by_id_resolve, now the function works.
6073 Affected file lib/silcclient/idlist.c.
6075 * Added function silc_net_get_local_port to get local bound
6076 port by socket. Added to lib/silcutil/silcnet.[ch].
6078 * Added `sockets' and `sockets_count' fields to the SilcClient
6079 object. They hold the sockets of the listenning sockets in
6080 the client. Listenning sockets may be for example the key
6081 agreement server. Affected file lib/silcclient/client.[ch].
6082 Added functions the silc_client_add_socket and the
6083 silc_client_del_socket. They are exported to the application
6086 * Added ~./silc/clientkeys to support other client's public keys.
6088 * Renamed verify_server_key client operation to verify_public_key
6089 and added one argument to indicate the type of the connection
6090 (server, client etc.).
6092 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Added silc_server_connection_auth_request to handle the
6095 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6096 silcd/packet_receive.[ch].
6098 * Added silc_server_send_connection_auth_request into the
6099 silcd/packet_send.c to send the connection auth request packet.
6101 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6104 * Fixed the public key authentication in responder side in the
6105 server. The `auth_data' pointer includes the SilcPublicKey
6106 not the path to the public key. Affected file silcd/protocol.c.
6108 * Implemented the public key authentication in the initiator side
6109 in the server. Affected file silcd/protocol.c.
6111 * Removed the [RedirectClient] config section from the server
6112 configuration. Is not needed and I don't want to implement it.
6114 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Cleaned up the CMODE command in the server. It now works
6117 correctly and supports all the modes defined in the protocol.
6118 Affected file is silcd/command.c.
6120 * Added `hmac_name' field to the SilcChannelEntry in the server
6121 to hold the default HMAC of the channel. It can be set when
6122 creating the channel (with JOIN command). Affected files
6125 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6126 type to indicate the change of the current cipher and hmac
6127 on the channel. Client can safely ignore the <cipher> argument
6128 (if it chooses to do so) since the CHANNEL_KEY packet will
6129 force the channel key change anyway. The <hmac> argument is
6130 important since the client is responsible of setting the new
6131 HMAC and the hmac key into use.
6133 * Fixed the CMODE command in the client library as well.
6135 * Tested CMODE command in router environment successfully.
6137 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Show the version of the remote client (or server) when connecting
6140 to the server. It is logged to the log file. Affected file
6141 is silcd/protocol.c.
6143 * Fixed the KILLED notify handling in the client library. The
6144 client must be removed from all channels when receiving the
6147 Also, do not remove the client entry when giving the KILL
6148 command but when the KILLED notify is received.
6150 * Removed silc_idlist_find_client_by_nickname from the server.
6151 Not needed anymore. Affected files silcd/idlist.[ch].
6153 * Implemented the CHANNEL_CHANGE notify type handling to the
6154 server. Affected file silcd/server.c.
6158 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Added silc_server_send_notify_invite to send the INVITE
6161 notify between routers.
6163 * Implemented the INVITE command correctly to the server.
6165 * Implemented the INVITE notify type handling in the server.
6167 * Implemented the INVITE command to the client library and on the
6170 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Added function silc_server_get_client_resolve to find the
6173 client entry by ID from all ID lists and then resolve it
6174 (using WHOIS) if it cannot be found. Affected file is
6177 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Implemented the BAN command to the client library.
6181 * The JOIN command in the server now checks the invite list
6184 * Changed the silc_command_reply_payload_encode_va and the
6185 silc_command_payload_encode_va to support that if argument is
6186 NULL it ignores and checks the next argument. Affected file
6187 lib/silccore/silccommand.c.
6189 * Added silc_server_send_notify_ban to send the BAN notify
6190 type between routers.
6192 * Chaned the silc_notify_payload_encode to support that if
6193 argument is NULL it ignores and checks the next argument.
6194 Affected file lib/silccore/silcnotify.c.
6196 * Tested ban lists in router environment successfully.
6198 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Implemented BAN command to the server, in silcd/command.[ch].
6202 * Removed the BAN and INVITE_LIST modes from the CMODE command
6205 * Added function silc_string_match to regex match two strings.
6206 Affected files lib/silcutil/silcutil.[ch].
6208 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Redefined parts of the SilcChannelEntry in the server to support
6211 the new ban and invite lists.
6213 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Redefined the INVITE command. The same command can be used to
6216 invite individuals to the channel but also to manage the invite
6217 list of the channel (to add to and remove from the invite list).
6218 Updated the protocol specs.
6220 * Added new command SILC_COMMAND_BAN that can be used to manage
6221 the ban list of the channel. Updated the protocol specs.
6223 * Removed the channel modes: the SILC_CMODE_BAN and the
6224 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6225 in the CMODE command. The equivalent features are now available
6226 using INVITE and BAN commands. Updated the protocol specs.
6228 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6229 in the network about change in the current ban list. The notify
6230 type is not used by the client.
6232 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6233 support the invite lists.
6235 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Added new function silc_string_regexify that converts string
6238 including wildcard characters into regex string that can
6239 be used by the GNU regex library. Added into the file
6240 lib/silcutil/silcutil.[ch].
6242 Added silc_string_regex_combine to combine to regex strings
6243 into one so that they can be used as one regex string by
6244 the GNU regex library. Added into the file
6245 lib/silcutil/silcutil.[ch].
6247 Added silc_string_regex_match to match two strings. It returns
6248 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6250 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Imported GNU regex to the soruce tree into lib/contrib.
6253 Fixed some compiler warning from the regex.c.
6255 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Fixed MOTD command in the server to work in router environment.
6259 * Fixed the MOTD command in the client library to support
6260 the server argument in the command.
6262 * Added `nickname_len' argument to the silc_idlist_add_client
6263 in the server, as the `nickname' argument may be binary data
6266 * Added silc_idlist_get_channels to return all channels from
6269 * Implemented LIST command to the server. Affected file is
6272 * Implemented the LIST command to the client library and on the
6275 * Added [<user count>] argument to the LIST command reply.
6276 With private channels the user count is not shown.
6278 * Updated TODO and README.
6280 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * The client entry's data.registered must be TRUE even with
6283 global client entry on global client list. The data.registered
6284 is used to check whether the client is anymore in the network,
6285 for example with WHOWAS command so it must be valid.
6287 * Fixed the WHOWAS command in the server. It now actually works
6288 in router environment. Added function into silcd/command_reply.c
6289 silc_server_command_reply_whowas_save.
6291 * Added silc_idlist_purge function to the silcd/idlist.c
6292 to periodically purge the ID Cache.
6294 * Fixed INFO command in the server. It works now in router
6295 environment. Added <server name> argument to the INFO command
6296 reply. Updated the protocol specs.
6298 * Fixed minor bug in silc_idcache_purge to not purge if the
6299 expire value is zero.
6301 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6302 they were buggy because of the WHOWAS information.
6304 * Fixed local command MSG to handle the async resolving of
6305 the remote client properly. It used to fail the first MSG.
6306 Affected file silc/local_command.c.
6308 * Added `data_len' field to SilcIDCache context.
6310 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Update TODO. Todo in commands in the server.
6314 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6317 used by routers as broadcast packet to inform other routers
6318 about the changed user mode.
6320 Implemented the notify handling in the server. Affected file is
6321 silcd/packet_receive.c. Added the function
6322 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6324 * Added new generic Channel Payload and deprecated the New Channel
6325 Payload. The New Channel Payload is now the generic Channel
6328 * Added new argument `mode' to the silc_server_send_new_channel
6329 as it is required in the Channel Payload now.
6331 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6332 and created a new and real SilChannelPayload to represent the
6333 new generic Channel Payload. Implemented the encode/decode
6334 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6336 * Added silc_server_get_client_channel_list to return the list
6337 of channels the client has joined for WHOIS command reply.
6338 Affected file silcd/server.[ch].
6340 * Implemented the channel list sending in the WHOIS command reply
6341 in server and in the client.
6343 Implemented the channel list displaying on the user interface
6344 as well. Affected file silc/client_ops.c.
6346 * Added silc_channel_payload_parse_list to parse list of Channel
6347 Payloads. It returns SilcDList list of SilcChannelPayloads.
6348 Client for example can use this function to parse the list of
6349 channels it receives in the WHOIS command reply. The caller
6350 must free the list by calling silc_channel_payload_list_free.
6351 Affected files lib/silccore/silcchannel.[ch].
6353 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Added one new argument <user mode> to the WHOIS command reply
6356 to return the mode of the user in SILC. Updated the protocol
6359 Implemented it to the server and client.
6361 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Fixed the mode printing on the user interface on joining.
6364 Affected file silc/client_ops.c.
6366 * Implemented the UMODE command and user modes in general to the
6367 client library and to the user interface.
6369 * Implemented the UMODE command to the server.
6371 * The server now sends UNKNOWN_COMMAND error status if client sends
6372 unknown command. Affected file silcd/command.c.
6374 * All server commands now handle the command identifier the right
6375 way when sending the command reply to the client. The client can
6376 use to identify the command replies with the identifier.
6378 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Added silc_server_get_client_route to resolve the route to
6381 the client indicated by the client ID. Affected file is
6384 * Added silc_server_relay_packet as general function to relay
6385 packet to arbitrary destination. This deprecates functions
6386 like _send_private_message_key, _relay_notify etc. Affected
6387 file is silcd/packet_send.[ch].
6389 Removed silc_server_send_key_agreement,
6390 silc_server_send_private_message_key and
6391 silc_server_packet_relay_notify functions from the file
6392 silcd/packet_send.[ch].
6396 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6397 server. Affected file silcd/packet_receive.[ch].
6399 * Implemented the KILL command to the client. Implemented the
6400 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6401 Affected files lib/silcclient/command[_reply].c and
6402 lib/silcclient/client_notify.c. Implemented the KILL notify
6403 printing in the user inteface.
6405 * Fixed a lot silc_parse_nick memory leaks from the client
6406 library in the file lib/silcclient/command.c.
6408 * Changed the silc_server_send_notify_on_channels's `sender'
6409 argument from SilcSocketConnection to SilcClientEntry to
6410 check the sender as entry and not as connection object and not
6411 to send to the client provided as argument. The affected file
6412 is silcd/packet_send.[ch].
6414 * The notify packets that are destined directly to the client used
6415 to not to be processed by the server. Now changed that and the
6416 server processes all notify packets. After relaying the packet
6417 to the client the notify packet is processed in the server.
6419 * The silc_server_free_client_data now checks whether there is
6420 pending outgoing traffic for the client and purges the data to
6421 the network before removing the client entry.
6423 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6426 an client is killed from the SILC Network. Updated the protocol
6429 Added new function silc_server_send_notify_killed to the
6430 silcd/packet_send.[ch].
6432 * Added function silc_server_packet_relay_notify to relay notify
6433 packets that are destined directly to a client. In this case
6434 the server does not process the notify packets but merely relays
6435 it to the client. Affected file silcd/packet_send.[ch].
6437 Added also silc_server_packet_process_relay_notify to check
6438 whereto relay the notify. Affected file is
6439 silcd/packet_receive.[ch].
6441 * Implemented the KILL command to the server.
6445 * Added the backup schema desgined last fall to the protocol
6446 specs for everyone to see. The specification is in the
6447 *-spec-xx.txt draft and the packet type definitions for the
6448 backup routers is in *-pp-xx.txt draft. Thusly, added also
6449 new packet type SILC_PACKET_CELL_ROUTERS.
6451 * A big security problem in the implementation discovered. The
6452 signoff of an client did not cause new channel key generation
6453 which it of course should've done. The channel keys must be
6454 always re-generated when client leaves (or signoffs) the channel.
6455 The silc_server_remove_from_channels funtion now handles
6456 the channel key re-generation.
6458 * Added `sender' argument to the silc_server_send_notify_on_channels
6459 to not to send the client provided as argument. Affected file
6460 silcd/packet_send.[ch].
6462 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Implemented OPER and SILCOPER commands into the server and
6467 * Added silc_auth_verify and silc_auth_verify_data to verify
6468 the authentication directly from the authentication payload.
6469 It supports verifying both passphrase and public key based
6470 authentication. Affected file lib/silccore/silcauth.[ch].
6472 * Added `hash' field to the SilcIDListData structure. It is the
6473 hash negotiated in the SKE protocol. Affected file is
6476 * Slight redesigning of the SilcAuthPayload handling routines.
6477 Do not send SilcPKCS but SilcPublicKey as argument.
6479 * Implemented the public key authentication support to the
6480 serverconfig. The public key is loaded from the provided path
6481 and saved as authentication data to void * pointer. Thus,
6482 changed the unsigned char *auth_data to void *auth_data;
6484 * Fixed SHUTDOWN command to send the reply before the server
6485 is shutdown. :) Affected file silcd/command.c.
6487 * Fixed fatal bug in CONNECT command. The hostname was invalid
6488 memory and server crashed. Affected file silcd/command.c.
6490 * Fixed fatal bug in CLOSE command. The server_entry became
6491 invalid but was referenced later in the command. Affected file
6494 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Fixed fatal bug in failure packet handling. Server ignored
6497 the failure and thus crashed when it came.
6501 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6504 that the command may be executed only once in (about) 2 seconds.
6505 The old SILC_CF_LAG flag is same but allows command bursts up
6506 to five before limiting.
6508 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6509 server code. Various commands now includes the CF_LAG_STRICT
6510 flag to disallow any kind of miss-use of the command.
6512 * Fixed the silc_buffer_unformat to not to allocate any data
6513 if the length of the data is zero. It used to allocate the
6514 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6516 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Changed the format of AdminConnection configuration section
6519 in the server. Added username of the admin to the format.
6520 Affected files silcd/serverconfig.[ch].
6522 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6523 to return admin configuration data by host, username and/or
6526 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Implemented WHOWAS command to the server. Added the functions:
6530 silc_server_command_whowas_parse,
6531 silc_server_command_whowas_send_reply,
6532 silc_server_command_whowas_from_client and
6533 silc_server_command_whowas_from_server
6535 * Added <Client ID> argument to the WHOWAS command reply. Updated
6536 the protocol specs accordingly.
6538 * Implemented WHOWAS command and command_reply to the client
6541 Implemented the WHOWAS printing on the user interface.
6543 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added new argument to the WHOWAS command reply, the real name.
6546 It is an optional argument. Updated the protocol specs.
6548 * Added SilcIDCacheDestructor callback that is registered when
6549 the SilcIDCache is allocated. The callback is called when
6550 an cache entry in the ID Cache expires, or is purged from the
6551 cache. Added into lib/silccore/idcache.[ch].
6553 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6554 to destruct the client entries when the cache entry expires.
6555 Other ID Cache's in server and in the client library ignores
6558 * If the ID Cache entry's `expire' field is zero then the entry
6559 never expires. Added boolean `expire' argument to the
6560 silc_idcache_add function in the lib/silccore/idcache.[ch].
6561 If it is TRUE the default expiry value is used.
6563 * Added silc_server_free_client_data_timeout that is registered
6564 when client disconnects. By default for 5 minutes we preserve
6565 the client entry for history - for WHOWAS command.
6567 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Added support to the server to enforce that commands are not
6570 executed more than once in 2 seconds. If server receives
6571 commands from client more frequently, timeout is registered
6572 to process the commands. Affected file silcd/command.c.
6573 Added new function silc_server_command_process_timeout.
6575 * Changed NICK_NOTIFY handling in client library to check that
6576 if the client's nickname was changed, so there is no need to
6577 resolve anything from the server.
6579 * Removed error printing from the WHOIS and IDENTIFY commands.
6580 If error occurs then it is ignored silently in the client library.
6581 The application, however, may map the received error to
6582 human readable error string. The application currently maps
6583 the NO_SUCH_NICKNAME error to string.
6585 * Made the command status message public to the application. Moved
6586 them from lib/silcclient/command_reply.c to
6587 lib/silcclient/command_reply.h. The application can map the
6588 received command status to the string with the
6589 silc_client_command_status_message function.
6591 * Added check to the server to check that client's ID is same
6592 as the Source ID in the packet the client sent. They must
6595 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Added dist-bzip hook to the Makefile.am to make bzip2
6598 compressed distributions.
6600 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Server now enforces the maximum length for the nickname and
6603 the channel as protocol specification dictates. 128 bytes for
6604 nickname and 256 bytes for channel name.
6606 * Moved the WHOIS printing to the application. The client libary
6607 does not print out the WHOIS information anymore, the application
6608 must do it. Renamed silc_client_command_reply_whois_print to
6609 the silc_client_command_reply_whois_save.
6611 The client's idle time is also sent to the application now, and
6612 the idle is shown on screen.
6614 * Added silc_client_command_reply_identify_save to save the
6615 received IDENTIFY entries.
6617 * Do not check for channel private keys in message sending and
6618 reception if the channel does not have the PRIVKEY mode set.
6619 Affected file lib/silclient/client_channel.c.
6621 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6624 just surfaced after chaning the JOIN procedure.
6626 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added silc_client_get_clients_by_list to get client entries
6629 from Client ID list, that is returned for example by JOIN
6630 and USERS command replies. The application should use this
6631 function for example when JOIN command reply is received to
6632 resolve the clients already on the channel (library does not
6633 do that anymore as USERS command reply is not used in the JOIN
6634 procedure anymore). Affected files lib/silcclient/silcapi.h and
6635 lib/silcclient/idlist.c.
6637 * JOIN command reply and USERS command reply returns now SilcBuffer
6638 pointers instead of unsigned char pointers when returning
6639 the client list and mode list.
6641 * Added <Client ID> argument to the JOIN command reply, mainly
6642 for the server to identify for which client the command was
6643 originally sent. Updated protocol specs accordingly.
6645 * Added SilcDlist private_key pointer to the SilcChannelEntry
6646 in the client to support the channel private keys. Affected
6647 file is lib/silcclient/idlist.h.
6649 * Added SilcChannelPrivateKey argument to the function
6650 silc_client_send_channel_message so that application can choose
6651 to use specific private ke if it wants to. If it is not provided,
6652 the normal channel key is used, unless private keys are set.
6653 In this case the first (key that was added first) is used
6654 as the encryption key.
6656 * Implemented the support for channel private key handling.
6657 Implemented the following functions:
6659 silc_client_add_channel_private_key,
6660 silc_client_del_channel_private_keys,
6661 silc_client_del_channel_private_key,
6662 silc_client_list_channel_private_keys and
6663 silc_client_free_channel_private_keys
6665 Affected file lib/silcclient/client_channel.c.
6667 * Added the support for the private keys in the channel message
6668 sending and encryption and in the message reception and
6669 decryption. Affected funtions are
6670 silc_client_send_channel_message and silc_client_channel_message.
6672 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Added SKE's key verify callback to the client library's
6675 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6677 * Removed the statement that server (or router) must send USERS
6678 command reply when joining to the channel so that the client
6679 knows who are on the channel. Instead, the client list and
6680 client's mode list is now sent in the JOIN command reply to the
6681 client who joined channel. This is better solution.
6683 * Added function silc_server_get_users_on_channel and function
6684 silc_server_save_users_on_channel to the silcd/server.[ch].
6686 * Removed function silc_server_command_send_users from the
6689 * Do not show topic on the client library anymore. The topic is
6690 sent in the command reply notify to the application and the
6691 application must show the topic now.
6693 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Added client searching by nickname hash into the IDENTIFY and
6696 WHOIS commands in the server as they were clearly missing from
6697 them. Affected file is silcd/command.c.
6699 * Fixed a bug in private message receiving in the client library.
6700 The remote ID was freed and it wasn't supposed, now it is
6703 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Minor fix to the channel payload; allocate the data area, as it
6706 needs to be of specific length.
6708 * If the key agreement port is zero then the operating
6709 system will define the bound port. Affected files are
6710 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6712 * Added new function silc_channel_payload_decrypt into the file
6713 lib/silccore/silcchannel.[ch].
6715 * Moved the channel message etc, check from silc_packet_decrypt
6716 to applications. The library calls now a generic
6717 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6718 when the packet is either normal or special. This was done to
6719 allow more wide range of checking that was not allowed when
6720 the code was in library. Now applications can do virtually any
6721 checks to the packet and return to the library the decision how
6722 the packet should be processed. Affected files are
6723 lib/silccore/silcpacket.[ch].
6725 Added silc_server_packet_decrypt_check to the server and
6726 silc_client_packet_decrypt_check to the client library.
6728 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6729 to send with specified source and destination information.
6731 * Channel message delivery between routers was broken after the
6732 channel key distribution was fixed earlier. The channel key
6733 was used be to distributed to other routers as well which is not
6734 allowed by the protocol. Now this is fixed and channel keys
6735 really are cell specific and the channel message delivery between
6736 routers comply with the protocol specification.
6738 * Fixed various commands in server to check also the global list
6739 for the channel entry and not just the local list. The affected
6740 file silcd/command.c.
6742 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Added assert()s to buffer formatting and unformatting routines
6745 to assert (if --enable-debug) when error occurs. Affected
6746 file: lib/silcutil/silcbuffmt.c.
6748 * Changed to auto-reconnect to check whether the remote host is
6749 router and register the re-connect timeout if it is. It used
6750 to check that whether we are normal server, but router must do
6751 auto-reconnect with another router as well. Affected file
6754 * Removed the [<key len>] option from CMODE command as the cipher
6755 name decides the key length, nowadays. See the defined ciphers
6756 from the protocol specification.
6758 * Added [<hmac>] option to the CMODE command to define the HMAC
6759 for the channel. Added SILC_CMODE_HMAC channel mode.
6761 * Added [<hmac>] option for the JOIN command so that user can
6762 select which HMAC is used to compute the MACs of the channel
6765 * Added Hmac field to the Channel Message Payload. The integrity
6766 of plaintext channel messages are now protected by computing
6767 MAC of the message and attaching the MAC to the payload. The
6768 MAC is encrypted. Now, it is clear that this causes some
6769 overhead to the size of the packet but rationale for this is that
6770 now the receiver can verify whether the channel message decrypted
6771 correctly and also when private keys are set for the channel the
6772 receiver can decrypt the packet with several keys and check from
6773 the MAC which key decrypted the message correctly.
6775 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6776 lib/silccrypt/silccipher.[ch].
6778 * Added silc_hash_len to return the digest length into the
6779 lib/silcrypt/silchash.[ch].
6781 * Rewrote parts of Silc Channel Payload interface in the
6782 lib/silccore/silcchannel.[ch]. The encode function now also
6783 encrypts the packet and parse function decrypts it.
6785 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Fixed a minor formatting bug in the SKE's key material processing.
6788 It actually might have processed the keys wrong way resulting
6791 * Redefined the mandatory HMAC algorithms and added new algorithms.
6792 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6793 and hmac-md5 truncated to 96 bits. The mandatory is now
6794 hmac-sha1-96. Rest are optional (including the one that used
6795 to be mandatory). Rationale for this is that the truncated HMAC
6796 length is sufficient from security point of view and can actually
6797 make the attack against the HMAC harder. Also, the truncated
6798 HMAC causes less overhead to the packets. See the RFC2104 for
6801 * Added new [hmac] configuration section. The SKE used to use
6802 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6803 is of course wrong. The official names that must be proposed in
6804 the SKE are the ones defined in the protocol specification
6805 (hmac-sha1-96 for example). The user can configure any hmac
6806 using any hash function configured in the [hash] section. At
6807 least, the mandatory must be configured.
6809 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6811 * Added HMAC list to the SKE proposal list. It has now both
6812 hash algorithm list and HMAC list. This makes the protocol
6813 incompatible with previous versions. The SKE now seems to work
6814 the way it is supposed to work, for the first time actually.
6816 * Defined plain Hash algorithms to the protocol specification.
6819 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Implemented support for key agreement packets into the server.
6822 Added functions silc_server_key_agreement and
6823 silc_server_send_key_agreement. Other than these functions,
6824 server has nothing to do with this packet.
6826 * Added support for private message key packets into the server.
6827 Added functions silc_server_private_message_key and
6828 silc_server_send_private_message_key.
6832 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6833 called in the protocol's final callback instead in the END
6834 protocol state. This makes a little more sense and in the same
6835 time in client we can use the same protocol routines for normal
6836 key exchange and to key agreement packet handling as well.
6838 * Added to both client's and server's KE protocol context the
6839 SilcSKEKeyMaterial pointer to save the key material. We will
6840 bring the key material to the protocol's final callback by doing
6841 this. The final callback must free the key material.
6843 * Added SKE's packet_send callback into client's KE protocol
6844 context so that the caller can choose what packet sending function
6845 is used. This way we can use different packet sending when
6846 doing normal SKE when doing key agreement packet handling (in
6847 the key agreement packet handling we do not want to encrypt
6850 * Implemented the responder side of the key agreement routines
6851 in the client. The client can now bind to specified port and
6852 accept incoming key negotiation. The key material is passed
6853 to the application after the protocol is over.
6855 * Implemented the processing of incoming Key Agreement packet
6856 in the client. Added function silc_client_key_agreement to
6859 * Implemented the intiator side of the key agreement routines
6860 in the client. The client can now initiate key agreement with
6861 another remote client. The key material is passed to the
6862 application after the protocol is over.
6864 * Created client_keyagr.c to include all the key agreement
6867 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6868 SILC_TASK_CALLBACK except that it is not static.
6870 * Created client_notify.c and moved the Notify packet handling
6871 from the client.[ch] into that file.
6873 * Created client_prvmsg.c and moved all private message and
6874 private message key routines from the client.[ch] into that file.
6876 * Create client_channel.c and moved all channel message and
6877 channel private key routines from the client.[ch] into that file.
6879 * Changed silc_client_get_client_by_id_resolve to resolve with
6880 WHOIS command instead of IDENTIFY command, in the file
6881 lib/silclient/idlist.c.
6883 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6885 * Implemented the SKE's responder side to the Client library.
6887 * When FAILURE is received to the protocol do not trust it
6888 blindly. Register a timeout to wait whether the remote closes
6889 the connection as it should do it, only after that process the
6890 actual failure. This was changed to both client and server.
6892 * Added client_internal.h to include some of the structures
6893 there instead of client.h in lib/silcclient/.
6895 * Added function silc_task_unregister_by_callback to unregister
6896 timeouts by the callback function.
6898 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Some "Incomplete WHOIS info" errors has been appearing on the
6901 log files. Took away the entry->userinfo check from WHOIS
6902 reply sending. The entry->userinfo is now " " if client did not
6903 provide one. I thought this was fixed earlier but something
6904 is wrong still. Let's see if the error still appears.
6906 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Fixed a minor bug in the login when the channel key is
6909 re-generated in the server. It used to generate the key in
6910 wrong order and thus caused problems in the channel traffic.
6912 * Fixed a minor bug in channel key distsribution after
6913 KICK command. The key was not sent to the router even though
6916 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Added silc_ske_process_key_material_data as generic routine
6919 to process any key material as the SILC protocol dictates. The
6920 function is used by the actual SKE library but can be used by
6921 applications as well. This relates to the private message keys
6922 and the channel private keys since they must be processed the
6923 same way the normal SILC session keys. The protocol dictates
6924 this. Affected files: lib/silcske/silcske.[ch].
6926 Added also silc_ske_free_key_material to free the
6927 SilcSKEKeyMaterial structure.
6929 * Defined silc_cipher_set_key function to set the key for
6930 cipher without using the object's method function. The affected
6931 files: lib/silccrypt/silccipher.[ch].
6933 * Implemented silc silc_client_add_private_message_key,
6934 silc_client_add_private_message_key_ske,
6935 silc_client_del_private_message_key,
6936 silc_client_list_private_message_keys and
6937 silc_client_free_private_message_keys functions in the
6940 Added functions silc_client_send_private_message_key to send
6941 the Private Message Key payload and silc_client_private_message_key
6942 to handle incoming Private Message Key payload.
6944 * Added Cipher field to the Private Message Key payload to set
6945 the cipher to be used. If ignored, the default cipher defined
6946 in the SILC protocol (aes-256-cbc) is used.
6948 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Removed lib/silcclient/ops.h file.
6952 Redefined parts of the SILC Client Library API. Created new
6953 file silcapi.h that deprecates the ops.h file and defines the
6954 published Client Library API. Defined also private message key
6955 API and channel private key API into the file.
6957 This is the file that the application must include from the
6958 SILC Client Library. Other files need not be included by
6959 the application anymore.
6961 * Added new key_agreement client operation callback and also
6962 defined the Key Agreement library API for the application.
6964 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6967 is used by clients to request key negotiation between another
6968 client in the SILC network. If the negotiation is started it
6969 is performed using the SKE protocol. The result of the
6970 negotiation, the secret key material, can be used for example
6971 as private message key.
6973 Implemented the Key Agreement payload into the files
6974 lib/silccore/silauth.[ch].
6976 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Redefined ciphers for the SILC protocol. Added some new ciphers
6979 and defined the key lengths for the algorithms. Changed the
6980 code accordingly. The default key length is now 256 bits.
6982 * Fixed SKE key distribution function silc_ske_process_key_material
6983 when the key length is more than 128 bits. The default key
6984 length in SILC is now 256 bits.
6986 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6987 to indicate unsupported algorithm.
6989 * Renamed rijndael.c to aes.c and all functions as well.
6991 * Fixed a long standing channel key setting bug in client library.
6992 Weird that it has never surfaced before.
6994 * Fixed bug in channel deletion. If the entire channel is removed
6995 then it must also delete the references of the channel entry
6996 from the client's channel list as the client's channel entry and
6997 the channel's client entry share same memory.
6999 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Implemented CONNECT and SHUTDOWN commands in the client.
7003 * Implemented CLOSE command to the client.
7005 * Added the function silc_idlist_find_server_by_name into the
7006 files silcd/idlist.[ch].
7008 Added the function silc_idlist_find_server_by_conn into the
7009 files silcd/idlist.[ch].
7011 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * DIE command was renamed to SHUTDOWN. Updated the both code
7016 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7017 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7019 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7022 * Added function silc_server_create_connection function to create
7023 connection to remote router. My server implementation actually
7024 does not allow router to connect to normal server (it expects
7025 that normal server always initiates the connection to the router)
7026 so the CONNECT command is only good for connecting to another
7029 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7031 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7032 or some other client was kicked from the channel.
7034 Implemented the handling of the notify type to both client
7037 Implemented silc_server_send_notify_kicked to send the KICKED
7038 notify. It is used to send it to the server's primary router.
7040 * Implemented the KICK command into server and client.
7042 * Added `query' argument to the silc_idlist_get_client function
7043 to indicate whether to query the client from server or not if
7046 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7047 to indicate that the client is not channel founder.
7051 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * Removed the rng context from SilcPacketContext structure and
7054 changed that the packet routine uses the Global RNG API.
7056 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Added support for quit message that client can "leave" on the
7059 channel when it quits the SILC. It is ditributed inside the
7060 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7062 Added silc_server_free_client_data that will take the
7063 signoff message as argument.
7065 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7067 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Updated parts of the protocol specification to keep it up
7072 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7075 payloads in one packet.
7077 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7078 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7079 use now the new List flag.
7081 * Also deprecated the following packet types: REPLACE_ID,
7082 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7084 * Added list support for Notify packet in server.
7086 * Added silc_server_send_notify_channel_change to send the
7087 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7088 the silc_server_send_replace_id.
7090 * Added silc_server_send_notify_nick_change to send the
7091 NICK_CHANGE notify type. Deprecates the function
7092 silc_server_send_replace_id.
7094 * Added silc_server_send_notify_join to send the JOIN notify type.
7095 Deprecates the function silc_server_send_new_channel_user.
7097 * Added silc_server_send_notify_leave to send LEAVE notify type.
7098 Deprecates the function silc_server_send_remove_channel_user.
7100 * Added silc_server_send_notify_cmode and
7101 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7102 types. Deprecates the silc_server_send_set_mode function.
7104 * Added SERVER_SIGNOFF notify type to indicate that server has
7105 quit. This means that all clients on the channel from that
7106 server will drop. This can be also used when netsplit happens.
7108 Deprecated REMOVE_ID packet type since it is not needed anymore
7111 Added silc_server_send_notify_server_signoff to send the
7112 SERVER_SIGNOFF notify type. Deprecates the function
7113 silc_server_send_remove_id.
7115 Added also silc_server_send_notify_signoff to send the
7116 SIGNOFF notify type.
7118 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7119 SILC protocol from this day on. Changed the protocol
7120 specification as well.
7122 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7123 notify type. It is used between routers to notify about
7124 topic changes on a channel.
7126 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7129 * Partly updated the protocol specification to comply with the
7130 changes now made. It is still though a bit outdated.
7132 * The JOIN notify type now takes one extra argument <Channel ID>.
7133 The packet used to be destined to the channel but now the
7134 JOIN type may be sent as list thus it is impossible to
7135 destine it to any specific channel. By adding this argument
7136 it is again possible.
7138 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Added CREDITS file. The CHANGES and CREDITS file will appear
7141 in the distribution as well.
7143 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7146 types in the server's silcd/packet_receive.c.
7148 * Implemented CMODE and CUMODE to work in router environment.
7150 * Fixed minor encoding and decoding buglet from the
7151 lib/silccore/silcmode.c.
7153 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7156 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7158 * Changed all SilcConfigServer* and silc_config_server* to
7159 SilcServerConfig* and silc_server_config*, respectively.
7162 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Associated the ID (client or server ID) to the Authentication
7165 Payload to avoid any possibility of forging. Updated the
7166 protocol specification and the code accordingly.
7168 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7170 * The RSA key length is now save to the RsaKey context in the
7171 key generation process in lib/silccrypt/rsa.c. The key length
7172 is now used to figure out the maximum size of the block allowed
7173 to be encrypted/signed.
7175 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7176 is equivalent to the silc_mp_mp2bin but does not allocate any
7179 * Changed silc_mp_mp2bin API to take length argument. If it is
7180 non-zero then the buffer is allocated that large. If zero, then
7181 the size is approximated using silc_mp_sizeinbase, which however
7184 * Created Global RNG API which is global RNG that application can
7185 initialize. After initializing, any routine anywhere in the
7186 code (including library) can use RNG without allocating a new
7187 RNG object. This was done to allow this sort of use of the
7188 RNG in code that has no chance to allocate RNG object. All
7189 applications currently allocate this and many routines in the
7190 library use this. Affected file lib/silccrypt/silcrng.[ch].
7192 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7193 it to use the Global RNG API.
7195 * Defined Authentication Payload into protocol specification that
7196 is used during SILC session to authenticate entities. It is
7197 used for example by client to authenticate itself to the server
7198 to obtain server operator privileges.
7200 Implemented this payload into the lib/silccore/silcauth.[ch].
7201 Implemented also routines for public key based authentication
7202 as the new protocol specification dictates.
7204 Moved definitions of different authentication methods from
7205 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7207 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7208 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7209 silc_pkcs_verify_with_hash functions into the file
7210 lib/silccrypt/silcpkcs.[ch].
7212 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7214 * The client entry's userinfo pointer must be always valid.
7215 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7216 will fail since it requires the userinfo. Now, the userinfo
7217 is allocated as "" if actual userinfo does not exist. Actually,
7218 it must exist and it is totally Ok to drop client connections
7219 that does not announce the userinfo. However, we will make
7220 this workaround for now.
7222 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7223 to return the remote port by socket.
7225 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7228 SILC_SERVER_PENDING_EXEC and added an new macro
7229 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7230 data or when error occurs while processing the pending command.
7232 Added new argument `destructor' into silc_server_command_pending
7233 and to the SilcServerCommandPending object. This destructor is
7234 now called after calling the pending callback or if error occurs
7235 immediately. If error occurs the actual pending callback won't
7236 be called at all - only the destructor. The destructor may be
7237 NULL if destructor is not needed.
7239 All this applies for client library code as well. Similar
7240 changes were made there as well for the pending commands.
7242 In the client, the application must now allocate the
7243 SilcClientCommandContext with the silc_client_command_alloc
7246 * Added reference counter to the SilcServerCommandContext. Added
7247 function silc_server_command_alloc and silc_server_command_dup
7250 Same type of functions added to the client library for the same
7253 * Removed the cmd_ident from IDListData away since it is now
7254 global for all connections. It is the command identifier used
7255 in command sending and with pending commands. The affected file
7258 * Added reference counter to the SilcSocketConnection objecet to
7259 indicate the usage count of the object. The object won't be
7260 freed untill the reference counter hits zero. Currently only
7261 server uses this, and client ignores it. The client must be
7262 set to use this too later. The affected files are
7263 lib/silccore/silcsockconn.[ch]. Added also the function
7264 silc_socket_dup to increase the reference counter.
7266 This was mainly added because it is possible that the socket
7267 is removed underneath of pending command or other async
7268 operation. Now it won't be free'd and proper DISCONNECTING
7269 flags, etc. can be set to avoid sending data to connection that
7270 is not valid anymore.
7272 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7273 the connection. After that it sets SILC_SET_DISCONNECTED.
7274 It is, however, possible that the socket data is not still freed.
7275 The silc_server_packet_process now checks that data is not
7276 read or written to connection that is DISCONNECTED. The socket
7277 get's freed when the reference counter hits zero.
7279 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Changed the client operation API: channel_message operation's
7282 `sender' is now the client entry of the sender, not the nickname
7283 and the `channel' is the channel entry, not the channel name.
7285 In the private_message operation the `sender' is now also the
7286 client entry of the sender not the nickname.
7288 Affected file is lib/silcclient/ops.h and all applications
7289 using the client operations.
7291 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Moved the calling of ops->connect() from connect_to_server_final
7294 into receive_new_id functin since that is the point when the
7295 client is actually allowed to send traffic to network. The
7296 affected file is lib/silcclient/client.c.
7298 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7301 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7302 (if needs broadcasting) instead of broadcasting the packets one
7303 by one which would make a burst in the network traffic.
7305 * Added `broadcast' argument to the functions in silcd/server.[ch]
7306 silc_server_create_new_channel[_with_id] to indicate whether
7307 to send New Channel packet to primary router.
7309 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * Added new function into the silcd/server.[ch] files:
7312 silc_server_create_new_channel_with_id to create new channel with
7313 already existing Channel ID.
7315 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7316 lib/silccore/silcpacket.h. This packet is used t send list of
7317 Set Mode payloads inside one packet. Server uses this to set
7318 the modes for the channels and clients on those channels, that it
7319 announced to the router when it connected to it. The protocol
7320 specification has been updated accordingly.
7322 * The silc_server_new_channel did not handle the packet coming
7323 from normal server as it normally does not send that. However,
7324 when it announces its channels it does send it. Implemented
7325 the support for that.
7327 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7328 into the file lib/silccore/id.h.
7330 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Fixed memory leaks in the functions silc_idlist_del_client,
7333 silc_idlist_del_channel and silc_idlist_del_server in the file
7334 silcd/idlist.c. All of those leaked like a sieve.
7336 * Fixed some small memory leaks in the client's function
7337 silc_client_notify_by_server.
7339 * Added functions into silcd/server.c: silc_server_announce_clients,
7340 silc_server_announce_channels and silc_server_announce_server.
7341 These functions are used by normal and router server to announce
7342 to its primary router about clients, channels and servers (when
7343 router) that we own. This is done after we've connected to the
7346 These functions effectively implements the following packet types:
7347 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7348 and SILC_PACKET_NEW_ID_LIST.
7350 * Added new functions into the silcd/packet_receive.[ch]:
7351 silc_server_new_id_list, silc_server_new_channel_list and
7352 silc_server_new_channel_user_list to handle the incoming
7353 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7355 * Added support of changing Channel ID in the function
7356 silc_server_replace_id. If the server that announces a channel
7357 to the router already exists in the router (with same name but
7358 with different Channel ID), router is responsible to send
7359 Replace ID packet to the server and force the server to change
7360 the Channel ID to the one router has.
7362 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7363 client that the Channel ID has been changed by the router. The
7364 normal server sends this to the client. Client must start using
7365 the new Channel ID as the channel's ID.
7367 Implemented handling of this new type into lib/silcclient/client.c
7368 into the function silc_client_notify_by_server.
7370 * Added new function silc_idlist_replace_channel_id into the files
7371 silcd/idlist.[ch] to replace the Channel ID.
7373 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Call silc_server_command_identify_check always when processing
7376 the IDENTIFY command in silcd/command.c
7378 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7381 send keepalive packets. The packet can be sent by clients,
7382 servers and routers.
7384 Added function silc_socket_set_heartbeat into the file
7385 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7386 If not set, the heartbeat is not performed. The actual
7387 heartbeat is implemented in the low level socket connection
7388 library. However, application is responsible of actually
7391 Added silc_server_send_heartbeat to send the actual heartbeat
7392 packet into silcd/packet_send.[ch]. Server now performs
7393 keepalive with all connections.
7395 * Added silc_task_get_first function into lib/silcutil/silctask.c
7396 to return the timeout task with shortest timeout. There was a bug
7397 in task unregistration that caused problems. TODO has been
7398 updated to include that task system must be rewritten.
7400 * The client library will now resolve the client information when
7401 receiving JOIN notify from server for client that we know but
7402 have incomplete information.
7404 * Rewrote parts of silc_server_remove_from_channels and
7405 silc_server_remove_from_one_channel as they did not remove the
7406 channel in some circumstances even though they should've.
7408 * Encryption problem encountered in server:
7410 The LEAVE command used to send the Channel Key packet to the
7411 router immediately after generating it. However, the code
7412 had earlier sent Remove Channel user packet but not immediately,
7413 ie. it was put to queue. The order of packets in the router
7414 was that Channel Key packet was first and Remove Channel User
7415 packet was second, even though they were encrypted in the
7416 reverse order. For this reason, MAC check failed. Now, this
7417 is fixed by not sending the Channel Key packet immediately but
7418 putting it to queue. However, this is more fundamental problem:
7419 packets that are in queue should actually not be encrypted
7420 because packets that are sent immediately gets encrypted
7421 actually with wrong IV (and thus MAC check fails). So, packets
7422 that are in queue should be encrypted when they are sent to
7423 the wire and not when they put to the queue.
7425 However, the problem is that the current system has not been
7426 designed to work that way. Instead, the packet is encrypted
7427 as soon as possible and left to the queue. The queue is then
7428 just purged into wire. There won't be any fixes for this
7429 any time soon. So, the current semantic for packet sending
7432 o If you send packet to remote host and do not force the send
7433 (the packet will be in queue) then all subsequent packets to the
7434 same remote host must also be put to the queue. Only after the
7435 queue has been purged is it safe again to force the packet
7438 o If you send all packets immediately then it safe to send
7439 any of subsequent packets through the queue, however, after
7440 the first packet is put to queue then any subsequent packets
7441 must also be put to the queue.
7443 Follow these rules and everything works fine.
7445 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Added new function silc_server_remove_clients_by_server to
7448 remove all client entries from ID list when the server connection
7449 is lost. In this case it is also important to invalidate all
7450 client entires as they hold the invalid server entry. This
7451 fixes fatal bug when server has lost connection and will reconnect
7454 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7456 * Made some sanity checks to silc_server_daemonise like to check
7457 whether the requested user and group actually exists.
7459 * Added sanity check to SKE's silc_ske_responder_finish to check
7460 that the public and private key actually is valid.
7462 * Invalidate the client's nickname when receiving Replace ID
7463 packet and the Client ID is being replaced. This means that the
7464 server will query the nickname if someone needs it (client)
7467 * Sort the ID Cache in client library when the ID Cache data
7468 has changed (needs sorting).
7470 * Do not allow for SILC client to create several connections to
7471 several servers. The client does not support windows right now
7472 and generating multiple connections causes weird behaviour.
7474 Irssi-silc client does support windows and can handle several
7475 connections without problems, see: www.irssi.org and SILC plugin.
7477 * Fixed some places where client was added to the IDList. The
7478 rule of thumb is following (in order to get everything right):
7479 If the client is directly connected local client then the
7480 `connection' argument must be set and `router' argument must be
7481 NULL to silc_idlist_add_client function. If the client is not
7482 directly connected client then the `router' argument must
7483 bet set and the `connection' argument must be NULL to the
7484 silc_idlist_add_client function.
7486 * The funtion silc_server_packet_send_local_channel actually did
7487 not check whether the client was locally connected or not. It
7488 does that now. Fixed a bug related to LEAVE command.
7490 * Fixed Remove Channel User payload parsing bug in server's
7491 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7493 * The server's silc_server_save_channel_key now checks also the
7494 global ID list for the channel as it might not be in the local
7495 list. Fixed a bug related to LEAVE command.
7497 * Is this the end of the [<unknown>] buglet that has been lurking
7498 around for a long time? A little for loop fix in server's
7499 silc_server_command_whois_parse that is used by both IDENTIFY
7500 and WHOIS command. At least, this was a clear bug and a cause
7501 of one type of [<unknown>] buglet.
7503 * WHOIS and IDENTIFY commands call the function
7504 silc_server_command_[whois/identify]_check function even if
7505 we are not router server.
7507 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Added --with-gmp configuration option. If set the GMP
7510 is always compiled in the SILC source tree. If not set then
7511 it is checked whether the system has the GMP3 installed. If
7512 it has then the GMP won't be compiled (the system's headers
7513 and library is used), if it doesn't have it then the GMP is
7514 compiled in the SILC source tree.
7516 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Changed RSA private exponent generation to what PKCS #1
7519 suggests. We try to find the smallest possible d by doing
7520 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7521 not security fix but optimization.
7523 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Added new config entry [Identity] to fork the server and run
7526 it as specific user and group. A patch from Bostik.
7528 * Imported Dotconf configuration library into lib/dotconf.
7529 This will be used to create the SILC configuration files later.
7530 It will appear in the distsribution after this commit.
7532 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * A big code auditing weekend happening. Auditing code for
7535 obvious mistakes, bugs and errors. Also, removing any code
7538 Removed files for being obsolete:
7540 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7541 inline in the file lib/silcutil/silcbuffer.h)
7543 o lib/silcutil/silcbufutil.c (the header has inline versions)
7545 Changed code to fix possible error conditions:
7547 o The buffer formatting routines now check that the destination
7548 buffer really has enough space to add the data. This applies for
7549 both buffer formatting and unformatting
7550 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7551 unformatting was changed to accomodate following rules:
7552 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7553 sent to the function while XXX_*STRING will not allocate or copy
7554 the data into the buffer. Instead it sets the pointer from the
7555 buffer into the pointer sent as argument (XXX_*STRING used to
7556 require that the pointer must be allocated already). This change
7557 makes this whole thing a bit more consistent and more optimized
7558 (note that the data returned in the unformatting with XXX_*STRING
7559 must not be freed now). The routines return now -1 on error.
7561 o Tried to find all code that use buffer_format and buffer_unformat
7562 and added return value checking to prevent formatting and
7563 especially unformatting errors and possible subsequent fatal
7566 o Changed ske->x and ske->KEY to mallocated pointers in
7567 lib/silcske/silcske.h. Fixed possible data and memory leak.
7569 o Added return value checking to all *_parse* functions. Fixed
7570 many memory leaks as well.
7572 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7573 so that buffer overflows would not happen. All code now also
7574 checks the return value as it can fail.
7576 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Added reconnection support to server if the normal server looses
7579 its connection to the router (for example if router is rebooted).
7580 The server performs normal reconnection strategy implemented
7581 to the server. Affected file silcd/server.c.
7583 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Added new packet type SILC_PACKET_SET_MODE that is used to
7586 distribute the information about changed modes (for clients,
7587 channels and clients channel modes) to all routers in the
7588 network. Updated the protocol specification accordingly.
7590 Added functions into silcd/packet_send.c and
7591 silcd/packet_receive.c: silc_server_send_set_mode,
7592 silc_server_set_mode.
7594 Added new files silcmode.[ch] into lib/silccore that implements
7595 the encoding and decoding of Set Mode Payload. Added new type
7596 SilcSetModePayload. Moved the definitions of different modes
7597 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7599 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Oops, a little mistake in server's connection authentication
7602 protocol. The protocol is not ended with FAILURE but with
7603 SUCCESS if the authentication is Ok. :) Affected file is
7606 * Implemented NICK_CHANGE notify handling in server in the file
7607 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7608 the local clients on the channel. After the changing nickname
7609 in router environment snhould work and the [<unknown>] nickname
7610 should appear no more.
7612 The silc_server_replace_id function that receives the Replace ID
7613 payload now sends the NICK_CHANGE notify type also in the file
7614 silcd/packet_receive.c
7616 * Changed WHOIS and IDENTIFY command to support the maximum amount
7617 of arguments defined in protocol specs (3328 arguments). This
7618 fixed a bug that caused problems when there were more than three
7621 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added extra parameter, command identifier, to the
7624 silc_client_send_command so that explicit command identifier
7627 Changed that ID list routines uses specific command identifier
7628 when sending WHOIS/IDENTIFY requests to the server so that they
7629 can be identified when the reply comes back.
7631 Affected files lib/silcclient/command.[ch],
7632 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7634 * Added `sender' argument to silc_server_packet_send_to_channel
7635 to indicaet the sender who originally sent the packet to us
7636 that we are now re-sending. Ignored if NULL. Affected file
7637 silcd/packet_send.[ch].
7639 * Added some server statistics support in silcd/server_internal.h
7640 SilcServerStatistics structure and around the server code. Also
7641 send some nice statistics information when client is connecting
7644 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Fixed channel ID decoding in server's JOIN command reply in
7647 silcd/command_reply.c
7649 * Fixed braodcasting of replace ID payload to not to send it if
7650 we are standalone server in silcd/packet_receive.c.
7652 * Fixed all channel message sending routines to not to send
7653 packets to clients that has router set, since they are routed
7654 separately in the same function earlier. Affects file
7655 silcd/packet_send.c and all channel packet sending functions.
7657 * In USERS reply, res_argv[i] are not allocated, the table
7658 is allocated. Thus changed that free the table, not its
7661 * In server's whois_check and identify_check if the client is
7662 locally connected do not send any WHOIS commands - they are not
7665 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Fixed some minor bugs in client when sending WHOIS command. The
7668 arguments was in wrong order.
7670 * Removed statis function add_to_channel from server in
7671 silcd/command.c that was previously used with the joining but
7674 * Tested USERS command in router environment successfully with two
7675 routers, two servers and two clients.
7677 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * Reorganized the USERS command and command reply in client library
7680 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7681 When the command is given by user we register a pending command
7682 callback that will reprocess the command after the reply has been
7683 received from the server. When reprocessing the packet we then
7684 display the information. Thus, the USERS information is displayed
7685 now in the command callback instead of in the command reply
7686 callback. The processing of the command is same as previously
7687 when server has sent the command reply in the JOINing process.
7689 * Added to USERS command in silcd/command_reply.c to join the client,
7690 we didn't use to know about, to the channel after we've created
7691 a client entry for it. Also, for clienet we did know already still
7692 check whether it is on the channel or not and add it if not.
7694 * Removed silc_server_command_join_notify as the function and its
7697 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7699 * Changed the client's pending command handling to the same as the
7700 server's pending command handling. It is also now possible to
7701 execute command reply functions from other command reply
7702 function as the function callbacks for commands and command
7703 replies are one and same. The pending commands are not static
7704 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7705 in client connection context. Thus, pending commands are server
7706 connection specific as it is convenient.
7708 Changed the function silc_client_command_pending and
7709 silc_client_command_pending_del and added new function
7710 silc_client_command_pending_check. Removed the
7711 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7714 * Added cmd_ident, current command identifier, to the client
7715 connection context in lib/silcclient/client.h to keep track on
7716 command identifiers used in command sending. Client's command reply
7717 function handling now supports the mandatory command identifiers.
7719 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7720 funtions in client to fully support pending command callbacks.
7722 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7723 as one of the arguments to the application in the command reply
7726 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7727 before first releasing SILC but came back. Now it is removed again
7728 and should come back nomore. The FORWARDED flag was used only
7729 by the JOINing procedure by forwarding the command packet to router.
7730 Now, the JOINing procedure has been changed to more generic (due
7731 to various router environment issues) and FORWARDED is not needed
7732 anymore for anything. The protocol specification is yet to be
7735 Now, removed silc_server_packet_forward from server and the flag
7736 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7738 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Renamed NAMES command to USERS command. The NAMES was named that
7741 due to historical reasons. Now it is renamed. Also, rewrote
7742 parts of the USERS command. The nickname list is not sent anymore
7743 by the server. Only Client ID and mode lists are sent in the USERS
7744 command. Changed this also to the protocol specification.
7746 The client now resolves the names and stuff after it receives
7747 the USERS list from the server when joining to the channel.
7749 * WHOIS and IDENTIFY commands has been changed to support multiple
7750 Client ID's per command. One can now search for multiple users
7751 in the network by sending only one WHOIS or IDENTIFY command.
7752 Changed the code and the protocol specifications.
7754 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7755 uses silc_server_command_whois_parse to parse the request. */
7757 * If normal server, do not parse the WHOIS and IDENTIFY requests
7758 before sending it to the router. Saves some time.
7760 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7762 * Fixed JOIN command on client library. Wrong number of arguments
7763 used to crash the client.
7765 * Added silc_server_channel_has_global function to check whether
7766 channel has global users or not.
7768 * Added silc_server_channel_has_local function to check whether channel
7769 has locally connected clients on the channel.
7771 * The silc_server_remove_from_one_channel now checks whether the
7772 channel has global users or not after given client was removed from
7773 the channel. It also checks whether the channel has local clients
7774 on the channel anymore. If it does not have then the channel entry
7775 is removed as it is not needed anymore.
7777 * The silc_server_notify now checks on JOIN notify whether the joining
7778 client is one of locally connected or global. If it is global then
7779 the channel has now global users on the channel and that is marked
7780 to the channel entry. Also, it now saves the global client to
7781 global list who is joining and JOINs it to the channel. This is
7782 for normal server, that is.
7784 Changed silc_server_send_notify_on_channel,
7785 silc_server_packet_relay_to_channel and
7786 silc_server_packet_send_to_channel check if we are normal server
7787 and client has router set (ie. global client) do not send the
7788 message to that client, as it is already routed to our router.
7790 * Implemented LEAVE notify type handling in silc_server_notify
7793 * Tested LEAVE command in router environment successfully. Tested
7794 with two routers, two servers and two clients.
7798 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7800 * Implemented SIGNOFF notify type handling in silc_server_notify
7803 * silc_server_remove_id now removes the client entry from all channels
7804 it has joined and thusly sends SIGNOFF notify type.
7806 * Rewrote the NAMES list generation in server by removing two excess
7807 loops. The lists are created now inside one loop.
7809 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7811 * silc_server_remove_channel_user checks now also global list
7812 for channel and client.
7814 * silc_server_new_channel_user checks now both local and global
7815 list for channel and client. Fixed a bug in client id decoding.
7816 Used to decode wrong buffer.
7818 * silc_server_channel_message checks now both local and global
7819 list for channel entry.
7821 * Tested channel joining (hence JOIN) in router environment
7822 successfully. Tested with two routers, two servers and two
7825 * Tested channel message sending in router environment successfully.
7827 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * Added silc_server_save_channel_key into server.[ch] to save the
7830 received channel key in Channel Key payload processing. It is
7831 also used in JOIN command reply handling.
7833 Equivalent function silc_client_save_channel_key added into
7834 client.[ch] into client library.
7836 * Changed JOIN command reply to send information whether the channel
7837 was created or not (is existing already) and the channel key
7838 payload. Changed protocol specs accordingly.
7840 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7841 the request was sent by ID and not by nickname. Crashed on
7844 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7847 now correctly save the received data.
7849 * silc_server_free_sock_user_data now notifies routers in the
7850 network about entities leaving the network.
7852 At the same time implemented functions silc_server_remove_id
7853 and silc_server_send_remove_id to receive and send REMOVE_ID
7854 packets. The packet is used to notify routers in the network
7855 about leaving entities. The ID removed will become invalid in
7858 * Added function silc_idlist_del_server into server. Removes and
7859 free's server entry from ID list.
7861 * silc_server_private_message function now checks, if we are router,
7862 that the destination ID really is valid ID, naturally.
7864 * In router when NEW_ID packet is received (for new client) the
7865 hash of the Client ID is saved in the ID Cache but the
7866 client->nickname is set to NULL, instead of putting the hash
7869 IDENTIFY command now also checks that client->nickname must be
7870 valid. If it is not if will request the data from the server who
7871 owns the client. Added new function
7872 silc_server_command_identify_check.
7874 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7875 to set the command to already allocated Command Payload.
7877 * Tested private message sending in router environment with two
7878 routers, two servers and two clients. Fixed minor bugs and now
7881 * Fixed segfault from client's NAMES command. Used to crash if
7884 * Forwarded packets must not be routed even if it is not destined
7885 to the receiver. Changed server code comply with this.
7887 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7889 * Added `require_reverse_mapping' boolean value to ServerParams
7890 structure. If TRUE (not default) the server will require that
7891 the connecting host has fully qualified domain name.
7893 If the reverse mapping is not required and hostname could not be
7894 found the IP address is used as hostname.
7896 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7898 * Implemented version string checking to both client and server.
7899 The check is incomplete currently due to the abnormal version
7900 strings used in development version of SILC.
7902 * Changed all command functions in server to use the new
7905 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7907 * Changed char *data to unsigned char *data in ID Cache system to
7908 support binary data as ID Cache data. Changed code to support
7909 binary data in lib/silccore/idcache.c.
7911 * Renamed silc_server_packet_relay_command_reply to
7912 silc_server_command_reply as it is normal packet receiving
7913 function. Rewrote the function to accept command replys for
7914 servers and not only for clients.
7916 * Mark remote router always as registered server if we are connecting
7917 to it. Otherwise, commands sent by the router to us are ignored.
7919 * All ID List find routines now returns the ID Cache Entry pointer
7920 as well if requested.
7922 * WHOIS command works now in router environment, tested with two
7923 routers, two servers and two clients.
7925 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7926 in router environment (as it is almost equivalent to WHOIS) but
7927 hasn't been tested thoroughly. Added new functions:
7929 silc_server_command_identify_parse
7930 silc_server_command_identify_send_reply
7931 silc_server_command_identify_from_client
7932 silc_server_command_identify_from_server
7934 * Disabled route cache adding because adding two different ID's with
7935 same IP replaces the old cache entry thus giving wrong route.
7936 The entry->router->connection is always the fastest route anyway
7937 so route cache may not be needed. Of course, new routes maybe
7938 established after receiving the ID when the entry->router->connection
7939 might not be anymore the most optimal.
7941 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7943 * Add route cache for received ID for fast routing.
7945 * Added silc_server_packet_route to route received packet on router
7946 that is not destined to us.
7948 * Renamed silc_server_get_route to silc_server_route_get.
7950 * Added id_string and id_string_len fields into SilcServer to
7951 include encoded ServerID for fast comparing without excess
7952 encoding of the ID's.
7954 * Cleaned up WHOIS command on server side. Added following static
7957 silc_server_command_whois_parse
7958 silc_server_command_whois_check
7959 silc_server_command_whois_send_reply
7960 silc_server_command_whois_from_client
7961 silc_server_command_whois_from_server
7963 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7964 arguments in command replies. All command functions should be
7965 updated to use this macro.
7967 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7969 * Minor typo fixes on command reply handling on server.
7971 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added silc_server_command_add_to_channel internal routine to add
7974 the client to the channel after router has created the channel and
7975 sent command reply to the server.
7977 * Added generic silc_server_send_command to send any command from
7980 * Use static buffer with ID rendering instead of duplicating data.
7982 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7984 * Fixed a channel user mode bug when joining to a channel server gave
7985 everybody channel founder rights, oops.
7987 * We mark ourselves as the router of the incoming server connection
7988 if we are router ourselves. This way we can check in some packet
7989 sending functions whether it is locally connected server. For
7990 incoming router connections we put NULL.
7992 * For router sending packets locally means now always sending the
7993 packet cell wide; to local clients and local servers. For normal
7994 server sending packet locally means sending it to only local
7997 * Fixed the JOIN command to really work in router environment. If the
7998 channel is created it is always created by the router. Router is
7999 also responsible of making the initial joining to the channel,
8000 sending JOIN notify to the sending server and distributing
8001 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8002 does not exist server doesn't do anything else but forward the
8003 command to the router which performs everything.
8005 * Added silc_server_send_channel_key function to send the Channel Key
8008 * Added silc_server_create_channel_key to create new channel key. The
8009 channel key is now re-generated everytime someone joins or leaves
8010 a channel, as protocol dictates. Note: channel->key_len is the
8013 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8016 packet_receive.[ch] to separate packet sending and receiving
8017 routines. The server.[ch] now includes everything else including
8018 actual packet processing (writing and reading data) and other
8021 Renamed silc_server_private_message_send_internal to
8022 silc_server_send_private_message. The routine is still though
8023 used only to relay private messages as server does not send
8024 private messages itself.
8026 Renamed silc_server_new_channel to silc_server_create_new_channel
8027 and added new function sicl_server_new_channel that handles the
8028 incoming New Channel packet. Added also new sending function
8029 silc_server_send_new_channel to send New Channel Payload.
8031 * Added new function silc_server_notify to process incoming notify
8032 packet to the server/router. Server may then relay the notify
8033 to clients if needed.
8035 * Added new function silc_server_new_channel_user to process incoming
8036 New Channel User packet. Router will redistribute the packet and
8037 send JOIN notify to its local clients and locally connected servers
8038 if needed. Normal server will send JOIN notify to its local client
8039 on same channel when received this packet. Added also corresponding
8040 sending function silc_server_send_new_channel_user to sent the
8043 * Added boolean route argument to send_notif_to_channel and
8044 packet_send_to_channel functions to attempt to route the packet
8045 if it is TRUE and send only locally if it is FALSE.
8047 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8049 * silc_server_replace_id now broadcasts the received replace ID
8050 packet if it is not broadcast packet already. The router must
8051 broadcast to inform other routers about changed ID.
8053 * Added backpointer to server's router into SilcServer context in
8054 silcd/server_internal.h.
8056 * Fixed silc_server_packet_broadcast to send correct broadcast
8059 * The channel key is now distributed to the local client as soon
8060 as it is received from the router (in router environment) so that
8061 no other packet may be sent for the channel until client has
8064 * silc_server_remove_channel_user now broadcasts the received
8065 Remove Channel User packet if it is not broadcast packet already.
8066 The router must broadcast to inform other routers about removed
8069 * Added users field into SilcPacketContext that is a reference count
8070 of the context. One can increase the reference count by calling
8071 silc_packet_context_dup which is now changed to just increase the
8072 reference count instead of duplicating the data. The reference
8073 count is decresed by calling silc_packet_context_free that will
8074 free the data after the reference count hits zero.
8076 For now on the packet context and everything allocated into it
8077 (including the raw packet from network) must be freed by calling
8078 the new silc_packet_context_free function. Added also new function
8079 silc_packet_context_alloc that must be used now to allocate the
8080 context. This also means that if a routine is asynchronous from
8081 silc_[client/server]_packet_parse_type the packet context must
8082 be duplicated by calling silc_packet_context_dup. Otherwise it
8083 gets free'd after silc_[client/server]_packet_parse_type returns.
8084 Also, one must remember that if packet is duplicated then its
8085 reference count must be decresed by calling the free function as
8086 many times as it was duplicated.
8088 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8089 from both client and server.
8091 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8093 * Made joining to a channel working in router environment.
8095 * Cleaned up JOIN command on server side and create function
8096 silc_server_command_join_channel internal routine to make the
8099 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8101 * Changed silc_command_pending list to SilcDList. Also, added
8102 `ident' field to SilcServerCommandPending structure to identify
8103 the reply and to call correct callback.
8105 Added silc_server_command_pending_check function to replace the
8106 corresnponding macro. The silc_command_pending list is not
8109 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8110 to set identifier to previously allocated Command Payload. It
8111 is used to set identifier for command when resending Command
8114 * Added silc_command_payload_encode_payload to encode Command
8115 Payload buffer from SilcCommandPayload structure.
8117 * Added silc_argument_payload_encode_payload to encode Argument
8118 payload buffer from SilcArgumentPayload structure.
8120 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Changed WHOIS command to support router connection on server side.
8123 The whois request is always sent to router unless the server is
8124 standalone server. After server has received the reply from the
8125 router will it send the reply to the client.
8127 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8128 broadcast received broadcast packet. The function is used only
8129 by router. The broadcast packet is always sent to the router's
8132 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8133 render given ID to printable string, for log files for example.
8135 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8137 * Made basic router to router connections working. At least they
8138 can now connect to each other but nothing really works the way
8139 they are supposed - yet.
8141 * Added new initiator token to RouterConnection configuration
8142 file in silcd/serverconfig.[ch]. It is used to tell whether we
8143 are the initiator to the remote router or whether we'll expect
8144 the other end to connect.
8146 * Moved registering of listener task to silc_server_init, hence
8147 the server starts listenning as soon as it is run, even if it
8148 does not have connections to other routers. Let's see how well
8151 * Changed default connection retry timeouts for more suitable in
8154 * Removed cipher and such arguments from silc_idlist_add_client
8155 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8156 Added new function silc_idlist_add_data to add the keys and stuff
8159 * Added SilcIDListData structure and added it to SilcClientEntry
8160 and SilcServerEntry as their first field in the structure. This
8161 way we can explicitly cast the ID entries to the SilcIDListData
8162 structure and get common data for the entries. In past, we had
8163 to first check what type of connection it is and then cast it to
8164 correct ID entry type. Now, we can directly cast the opaque
8165 pointer to the SilcIDListData (no matter what ID entry it actually
8166 is) and get the data needed.
8168 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8170 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8171 in some circumstances even if threre were timeout tasks, though not
8172 IO tasks, but tasks anyway. Now fixed.
8174 * Defined SilcServerConnection structure to hold connection specific
8175 stuff about directly connected servers and routers. The definition
8176 is currently in silcd/server_internal.h. I thought about having
8177 a bit more important role fro this struct but for now it is used
8178 only when connecting to other server (or router actually).
8180 * Added connecting retry support in server when connecting to
8181 router(s). The retry feature implement exponential backoff
8182 algorithm. Also, added SilcServerParams structure to hold default
8183 parameters for server. For now, it include these retry settings
8184 and are hard coded. After server is moded to be as Silc Server
8185 Library this structure will be more important.
8187 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8189 * Changed client librarys channel->clients table to SilcList and
8190 changed code accordingly.
8192 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8194 * Changed client's channel table to SilcList and changed code
8195 accordingly. Also changed SilcChannelClientEntry to include back-
8196 pointer to the channel so that client entry can use that structure
8197 as list as well and we have fast cross-reference to the channel.
8198 This change dramatically decreased the complexity of channel
8199 handling with client entry and vice versa (removed one extra
8200 loop when searching for channel entry from many functions).
8202 * Changed server->sim from table to SilcDList and changed code
8205 * NAMES command can now be used from user interface. It will show
8206 the user list on the channel, neatly.
8208 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8209 Code now saves realname of the user if it becomes available.
8211 * Renamed configure.in to configure.in.pre and made ./prepare
8212 script to automatically add correct version string to
8213 configure.in which it creates from configure.in.pre.
8215 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8217 * NAMES command reply now shows users mode with the nickname when
8220 * Moved silc_client_ch[u]mode[_char] functions from
8221 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8222 place sucks, they are utility functions and should be in some
8225 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8227 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8230 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Added TRQ (efficient deque and list library) into lib/trq. This is
8235 a very good list library that is currently used in the SILC. Defined
8236 SilcList API over the library because I didn't like the API very
8237 much. See lib/trq/silclist.h for the API and examples of how to
8238 use the API. Fixed various places in the code to use the new
8239 SilcList API. The SilcList is meant for lists that has a structure
8240 already defined as a list. It is not suitable to add just some
8241 context to the list (in TRQ, the context is the list actually).
8243 So, I defined SilcDList that can be used for the purpose where
8244 predefined list structure does not exit. This can be used as
8245 such list. Now some context just can be added to the SilcDList.
8246 Currently this list is not used in the SILC just yet, though there
8247 are a lot places where this can replace dynamically allocated
8248 tables and I will fix these places, later, to use SilcDList.
8249 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8250 and use TRQ internally).
8252 Also fixed some annoying warning messages that the original TRQ
8253 code generated. Also minor changes to TRQ's Makefile.in.
8255 * Added support for querying by Client ID to both WHOIS and
8256 IDENTIFY commands into server, as required by the protocol.
8258 * Removed method function pointers from SilcBuffer structure. They
8259 weren't used to anything and just increased the context size for
8260 no good reason. This change also made silc_buffer_alloc and
8261 silc_buffer_free functions inline functions.
8263 * Disabled command flooding detection support until it's fixed so
8264 that it accepts commands in but does not execute them more than once
8267 * Added silc_net_localhost(), to return local hostname, into
8268 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8269 that must be initialized before calling silc_client_init.
8271 * Added new function: silc_server_send_notify_on_channels to send
8272 notify messages to all channels client has joined. It is assured
8273 that the message is sent only once per client.
8275 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8276 lib/silcutil/silcutil.[ch] as silc_format function. The new
8277 function is generic and is used by server as well, not only by
8278 the logging routines.
8280 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8281 the provided version string was not acceptable. Added new function:
8282 silc_ske_check_version into lib/silcske/silcske.h. The function
8283 must be implemented by the application (client or server) and it
8284 does not reside in the SKE library. The function checks the version
8285 string remote end sent.
8287 * Added back pointers (to opaque context and to SilcSocketConnection)
8288 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8290 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8291 duplicate packet context structure.
8293 * Changed `notify' client operation to send same arguments as client
8294 receives from server except for ID's. ID's are mapped to correct
8295 ID entry and that is returned. Also, if channel entry is not sent
8296 by server but the notify is for channel the channel entry is sent
8297 to application (otherwise application doesn't know that it is for
8298 channel (library gets it from packet's Destination ID)).
8300 * Added silc_client_remove_from_channels into client library to
8301 remove a client from all channels it has joined to. Used when
8302 received SIGNOFF notify from server. Added also new function
8303 silc_client_replace_from_channels to replace old ID entry with
8304 new ID entry on all channels. Used when received NICK_CHANGE
8307 * Fixed ID Cache list handling in silc_idlist_get_client in
8308 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8309 to get (or query) client by ID.
8311 * Updated TODO list.
8313 * Added connection authentication status message defined by the
8314 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8315 support for these into the code in client and server side.
8317 * Added generic function silc_client_send_command to send any command
8318 with variable argument list. Application should use this function
8319 to send commands if the command functions provided by the library
8320 does not suite for the application's user interface needs.
8322 * Added new `failure' client operation. Application is notified about
8323 received failure packet if client is executing a protocol. In this
8324 case the protocol's execution has failed.
8326 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8327 is required by the protocol.
8329 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8330 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8333 * Added status flag to SilcSKE object to indicate realtime status
8334 of the SKE protocol.
8336 * Application receives now exactly same command reply arguments as
8337 the library receives from server. However, if ID is received the
8338 corresponding ID entry is returned to the application (eg. Client
8339 ID is mapped to correct SilcClientEntry entry and that is returned).
8340 Changed command_reply client operation due to this change.
8342 * Changed all ID's in commands and in command replys as ID Payloads.
8343 Change affected both client and server side codes.
8345 All ID's sent in SILC network (with execption of ID's in SILC
8346 Packet header) are sent in ID Payload to support variable length
8349 * Server now notifies nick changes and notifies all clients on
8350 the channels about the new nickname (about the new Client ID,
8353 * Implemented CMODE command to change channel modes. Supports all
8354 channel modes defined by the protocol specs except ban and invite
8355 lists. (Also, private channel key mode is supported but support for
8356 setting private channel key in client is missing, thus, this mode
8357 has no effect on client side (except that server requires that the
8358 client uses private channel key and normal channel traffic does not
8361 Also, invite mode works per se, but INVITE command does not work
8362 yet correctly, so you can set channel as invite only channel but
8363 inviting clients to the channel does not work (it is yet to be
8364 thought what's the best way to do it).
8366 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8367 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8368 Implemented CUMODE command to change user's mode on the channel.
8369 Supports all modes defined by the protocol specs.
8371 * Added NAMES command reply to return users modes on the channel.
8373 * Removed unnecessary and slow ciphers from lib/silccrypt.
8375 * Set SO_KEEPALIVE option to connection sockets by default.
8377 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8379 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8380 redefined the Notify Payload into protocol specs.
8382 * Added silc_id_payload_parse_id to get ID directly from raw
8385 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8387 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8388 accept searching by Client ID as well.
8390 * Added support for LEAVE and SIGNOFF notify types in client library.
8392 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8393 to parse ID Payload from raw data.
8395 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8397 * Added flags parameter into silc_ske_assemble_security_properties
8398 function in lib/silcske/silcske.[ch].
8400 * Changed notify client operation to fit better for notify messages
8401 sent by server. The notify payload received from server is now
8402 passed to the application (after parsing it to SilcNotifyPayload).
8403 It is application's responsibility to retrieve the arguments
8404 from the payload and show the message the way it wants. The message
8405 sent by server is implementation specific.
8407 * Changed public keys to comply with the protocol specification.
8408 Old public keys are not supported anymore and are not compatible.
8410 * Removed nickname from Channel Payload as the latest draft removed
8411 it. The client must resolve the nickname from the NAMES command
8412 reply received when it joined the channel.
8414 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8416 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8418 * Fixed some errors in protocol specification drafts.
8420 * Created lib/silccore/silcnotify.c to implement Notify Payload
8421 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8422 generic payloads described by protocol specifications. The file
8423 includes implementations for ID Payload and Argument Payload.
8425 * Changed Command Payload implementation to use the new Argument
8426 Payload. Changed command_xxxx_payload to command_payload_xxxx
8427 to comply with SILC coding conventions.
8429 * Added suppport for Argument Payload handling in Notify Payload
8430 implementation as protocol requires it. Added the new support
8431 into server and client lib as well.
8433 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Added support for multiple nicknames on same channel. [n] is
8436 added locally to the nickname if there are more than one same
8437 nicknames on the channel.
8439 * Server now sends all nicknames that matched WHOIS request.
8440 Client also shows the list received from server.
8442 * Added TOPIC command to client side. User can now set and show
8443 current topic on channel.
8445 * Added MOTD command to client and server. Also, server sends the
8446 motd when client connects to the server.
8448 * Changed version strings to comply ISO 8601.
8450 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8452 * Fixed protocol error handling in client library. It should now
8453 cope even if the SKE fails for some reason.
8455 * Made new protocol specification drafts for submitting to IETF.
8457 * Implemented TOPIC command to server in silcd/command.c.
8459 * Added two new notify types into lib/silccore/silcnotify.h:
8460 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8461 notify nickname change and topic setting/change on a channel.
8463 * API change of command_reply operation in client library. The
8464 application gets now the status type received from server as well.
8466 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8470 * Cras fixed and optimized the packet handling even further and
8471 it should work now. Minor change to the prototype of function
8472 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8474 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8476 * Added new function into lib/silcutil/silcschedule.[ch]:
8477 silc_schedule_with_fd to select() a specified fd. The function
8478 returns after timeout expires or data arrives or goes. The
8479 function is used by packet routines to wait that all data is
8480 received from network.
8482 * Fixed data reading from network in lib/silccore/silcpacket.c.
8483 The code now assures that all data is read from the fd and then
8484 continues packet processing. This was a bug fix since the code
8485 used to drop some data in some circumstances.
8487 * Added new function into lib/silcclient/client.[ch]:
8488 silc_client_start_key_exchange to start key exchange after
8489 connection has been established to server. The code internally
8490 now uses this funtion but its main purpose was to provide it
8491 for applications that perform their own connecting. After
8492 application has created a connection it merely calls this
8493 function to start the key exchange between client and server.
8494 The library takes care of everything else after that.
8496 Updated also lib/silcclient/README to explain the usage of
8499 * Do not send to application information that connection has
8500 been established. Application gets notified it by connect
8503 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8505 * Applied cras's patch to add silc_schedule_one function. The
8506 function runs scheduler once and returns.
8508 * Fixed the scheduler after cras messed it up. The timeout
8509 handling works now as it's supposed to work.
8511 * Added into lib/silccore/ silcnotify.h to include notify
8512 message types support. Changed silc_server_send_notify*
8513 functions, in server.[ch], to support those new notify types.
8514 Added the support for the notify types into client library,
8515 as well. Added new notify client operation into ops.h in
8518 * Changed silc_server_packet_send_to_channel to send normal
8519 packets instead of just channel message packets. The function
8520 is now used to send the notify packets to channels. It is not
8521 used to send channel message packets anymore, as server never
8524 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8525 va_arg()s as it seems to require it nowadays. I guess, if SILC
8526 is compiled with older va_arg() the new code should work anyway.
8528 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8530 * Splitted core library. Core library (lib/silccore) includes
8531 now only SILC protocol specific core (and common) components.
8532 Created new utility library (lib/silcutil) that includes more
8533 generic purpose stuff. The stuff for util library was taken
8534 from the old core library. This was minor and easy split.
8536 * Created SILC Client Library (lib/silcclient) that includes
8537 implementation of the SILC client without user interface. This
8538 was major move from silc/ directory. The code has been changed
8539 so that it is transparent towards the user interface. The
8540 silc/ directory includes now the same user interface as before
8541 and it uses the new client library. Read lib/silcclient/README.
8542 Basicly, the client library performs everything else related
8543 to SILC except user interface handling. Also, configuration
8544 files are considered to be part of user interface and library
8545 does not handle them.
8547 This change also changed a lot of structures, function naming etc.
8548 Most important change was that SilcClientWindow object was
8549 renamed to SilcClientConnection in the client library. Created
8550 also new file lib/silcclient/ops.h. Also added new files
8551 silc/local_command.[ch] and silc/client_ops.[ch].
8553 All these changes were made to make it easier for user interface
8554 designers to create what ever user interface for the SILC client
8557 It is also expected that the server will be moved to lib
8558 directory as well and SILC Server Library will be created;
8559 sometimes in the future.
8561 * Removed Local commands from lib/silccore/silccommand.h as
8562 they are application specific and new client library does not
8563 handle any of those anymore.
8565 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8566 old client implementation in silc/.
8568 * Added support for callback functions in SILC_LOG_* macros.
8569 Application can now set its own callbacks that will be called
8570 instead of using the default functions that will always print
8571 the debug messages to stderr (or stdout). Also, debugging can
8572 now be disabled by setting silc_debug to FALSE and re-enabled by
8573 setting it to TRUE. Note, that logging will still work even
8574 if debugging is disabled.
8576 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8577 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8578 silc_log_reset_debug_callbacks.
8580 * To enable debugging in silc client one must give now -d
8581 option on command line.
8583 * Changed silc_schedule_init to automatically allocate task queues
8584 if they are not allocated before calling it.
8586 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8588 * Added GMP 3.1 into math library.
8590 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8592 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8593 a channel in SILC network. The packet is used by servers and
8594 routers to notify other routers that user has left a channel.
8595 This little feature was missing until now. Added the feature
8596 to protocol specification as well.
8598 Added functions: silc_server_send_remove_channel_user and
8599 silc_server_remove_channel_user into server.[ch].
8601 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8602 lib/silccore/silcpacket.h. However, they are not implemented
8605 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Fixed joining to a channel and sending channel messages
8608 between server and router. The channel message sending should
8609 now work inside a cell.
8611 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8613 * Fixed the private message sending between server and router.
8614 The private message sending should now work inside a cell.
8616 * Added silc_server_replace_id into server.[ch] to replace
8617 existing ID in the SILC network.
8619 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8620 and silc_idlist_replace_server_id into idlist.[ch] in server.
8622 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8624 * Fixed the server to server connections. Server can again now
8625 connect to router. Router to router connections probably does
8628 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8630 * Added dynamic protocol registering support. Now protocols can
8631 registered and unregistered on the fly. Patch by cras.
8633 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8635 * Added lib/contrib directory to hold routines that some platforms
8636 don't have but are needed by SILC.
8638 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8639 into lin/contrib to provide getopt() and getopt_long() for
8640 those who don't have it.
8642 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8644 * Added AWAY command to client. When away message is set and
8645 client receives a private message packet the client automatically
8646 replies to the sender with the away message.
8648 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8649 bug seemed to be the cause of recent problems when compiling
8652 * Added version detection support to SKE protocol specification
8653 and added the new changes to the SKE implementation as well.
8654 There were other minor changes in the SKE protocol as well.
8656 Many changes in lib/silcske/silcske.[ch] and in
8657 lib/silcske/payload.[ch].
8659 * Added ^U functionality, clear input line. Patch from cras.
8661 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8663 * Mainly small bugfixes on core library. Fixed some debugging
8664 logging and buffer overflow in silclog.c.
8666 * Updated config.sub and config.guess on the distribution tree.
8668 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8670 * Added command lagging support in server. Client may execute
8671 commands now only once in two seconds.
8673 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Optimized packet reception. MAC computation and checking is now
8676 also more optimized. A lot previously duplicated code is now
8677 used as generic by both client and server.
8679 * Fixed key pair generation in clientutil.c
8681 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8683 * Added into lib/silccore/silcbufutil.[ch] new function;
8684 silc_buffer_realloc.
8686 * Moved generic packet sending/encryption functions to
8687 lib/silccore/silcpacket.[ch] from client and server. Some
8688 rewriting of the functions.
8690 * Moved all generic packet reception/decryption functions to
8691 lib/silccore/silcpacket.[ch] from client and server. The
8692 packet processing is now much cleaner in both client and server.
8693 These were major changes in both client and server.
8695 * Created many common functions in server to do packet sending.
8696 Previously code were duplicated a lot, this has been removed
8699 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8701 * Rewrote major parts of the ID cache system. Don't know
8702 whether it is better now or not but at least the API is more
8705 * Major rewrite on ID cache stuff on client because of the ID
8706 cache API changes. Added idlist.c to client.
8708 * Also major rewrite on ID cache stuff on server as well.
8709 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8710 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8711 in hand, instead they are all put into the ID cache system now.
8712 All server_idlist_* routines uses ID cache now instead of
8713 traversing its own lists (those lists does not exist anymore).
8714 SilcIDList though still exists. Also, SilcXXXEntry's are
8717 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Finally made the SKE implementation compliant to the protocol
8720 specification. All mp integers are now binary encoded as
8721 opposed being HEX encoded.
8723 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8726 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8727 functions: silc_[encode/decode]_pem. Also added function
8728 silc_encode_pem_file to PEM encode with newlines ('\n') for
8731 * SILC public keys are now encoded either PEM or binary. Same
8732 option is for private keys as well. By default private keys
8733 are binary encoded and public keys PEM encoded. Silly HEX
8734 encoding were removed.
8736 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8737 function to create fingerprints.
8739 * Fixed a bug in SHA1; does not change the original data anymore.
8741 * Partly implemented INFO command on client and server side.
8742 Fixed CLEAR command. Changes to SERVER command; show current
8743 server(s) when giving command without arguments. Added
8744 VERSION command to client.
8746 * Added check to server that unregistered connections cannot
8747 execute commands (unless it is specificly allowed).
8749 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8751 * Fixed screen refresh.
8753 * Fixed channel joining bug from client. On some circumstances
8754 client tried to join to a channel it had already joined.
8756 * Added public key verification process into client's protocol.c.
8757 The client now verifies the public key from user and saves
8758 it into ~./silc/serverkeys/ directory.
8760 Added into: clientutil.[ch]: silc_client_verify_server_key.
8762 * Changed SKE protocol's silc_ske_initiator_finish function
8763 to accept callback function that verifies the received public
8764 key. Removed old silc_ske_verify_public_key function.
8766 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8768 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8769 silc_pkcs_private_key[_data]_set.
8771 * Made the password and public authentication more cleaner in
8772 server's protocol.c.
8774 * Removed historic and obsolete protocol `channel_auth' from
8775 both client and server.
8777 * Removed wrong way of sending command status messages from
8778 server to client in server's command.c. The old way violated
8779 protocol specification.
8781 Changes to silccore/silccommand.[ch]: removed
8782 silc_command_encode_status_payload -> not needed anymore,
8783 changed silc_command_encode_payload_va to accept extra
8784 argument on variable argument list. The argument type must
8785 now be provided to the function. Also, added new function:
8786 silc_command_encode_reply_payload_va which is same as
8787 normal command_encode_payload_va except command status type
8788 is provided as extra argument.
8790 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8792 * Added ~./silc directory handling. The directory includes the
8793 public and private keys for the client.
8795 Added silc_client_check_silc_dir, silc_client_create_identifier
8796 and silc_client_load_keys.
8798 * Implemented SILC protocol compliant public key. Added public
8799 and private key saving to and loading from files.
8801 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8802 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8803 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8804 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8805 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8807 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8808 silc_pkcs_load_[public/private]_key.
8810 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8812 * Added silc_server_get_route (route.[ch]) to get connection
8813 data for the fastest route for given ID.
8815 * Implemented INVITE command on client and server. The command
8816 were re-defined in the SILC Protocol Specification and the
8817 implementation now complies with the specification.
8819 * Implemented PING command on client and server.
8821 * Implemented NAMES command on client and server. The server side
8822 supports currently only normal server not router server yet.
8823 Some changes to NAMES definition in SILC protocol specification.
8825 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8827 * Implemented LEAVE command on client and server.
8829 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8830 again. This change was made to the protocol as well. Server
8831 should not violate the protocol specification anymore.
8833 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8835 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8836 was tested. SOCKS4 was not but should work anyway.
