3 * Made preliminary `make install' work.
5 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7 * Added SilcServerRekey context into silcd/idlist.h.
9 * Added the PFS support as defined in the specification to the
10 SKE protocol. Affected files lib/silcske/*.c.

24 library. Re-key is performed once in an hour, by default.
26 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
27 Added silc_client_rekey_callback and silc_client_rekey_final.
28 Affected files are lib/silcclient/protocol.[ch] and
29 lib/silcclient/client.[ch].
31 * Removed the `hmac_key' and `hmac_key_len' fields from the
32 SilcClientConnection structure; not needed. Affected file is
33 lib/silcclient/client.h.
37 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Do not ask whether user wants to use the negotiated private key
40 for private messages, just use it. Affected file is
43 * Added `send_enc_key' and `enc_key_len' fields to the
44 SilcIDListData structure since they are needed in the re-key
45 phase. Affected file is silcd/idlist.[ch].
47 * Implemented the simple re-key protocol into the server.
48 Affected files silcd/server.c and silcd/protocol.[ch]. The
49 re-key will be performed once in an hour, by default.
51 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
52 Added silc_server_rekey, silc_server_rekey_callback and
53 silc_server_rekey_final.
55 * Removed Tunneled flag from the protocol. Updated the code
56 and the specifications.
58 * Adde `pfs' field to the SilcIDListData to indicate whether
59 the PFS is to be performed in the re-key. Affected file is
62 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
65 int64 of at least the xintXX size. If void * is less that 4
66 bytes uint32 * will be used. Defined bool as boolean.
68 * Changed _ALL_ unsigned long and unsigned int to uint32,
69 unsgined short to uint16 in the source tree.
71 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
72 not handle clients that has entry->data.registered == FALSE.
73 They are not in the network anymore. Affected file is
76 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
78 * Implemented the sending of the SERVER_SIGNOFF notify in the
79 server. Affected file is silcd/server.c.
81 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
82 Added also silc_notify_payload_encode_args into the
83 lib/silccore/silcnotify.[ch].
85 * Implemented ther SERVER_SIGNOFF notify handling in the server.
86 Affected file silcd/packet_receive.c.
88 * Implemented the SERVER_SIGNOFF notify handling in the client
89 library. Affected file lib/silcclient/client_notify.c. Also,
90 implemnted the printing of the SERVER_SIGNOFF info to the
91 application. Affected file silc/client_ops.c.
93 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
94 if the deleting was successful. Affected file silcd/idlist.[ch].
96 * Added support for public key authentication in the connection
97 authentication protocol in the client library. Affected file
98 lib/silcclient/protocol.c.
100 * Changed the server's silc_idlist_get_clients_by_* interface
101 to support already allocated array so that new entries may be
102 added to pre-allocated array. Affected file silcd/idlist.[ch].
103 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
106 * All command reply functions in the server now calls the
107 pending command callback even if error occured. This way the
108 error will be delivered to the client as well. Affected files
109 silcd/command.c and silcd/command_reply.c.
111 * Fixed INFO command to return local server's info if no server
112 was provided. Affected file lib/silcclient/command.c.
114 * Removed RESTART command for good. Updated the code and the
117 * Rewrote parts of the task system. It is a bit simpler now.
118 Removed unsued task priorities. The affected files are
119 lib/silcutil/silctask.[ch].
121 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Moved the USERS printing from the library to the application.
124 Affected files lib/silcclient/command.c and silc/client_ops.c.
126 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Added channel key re-key support. The re-key is perfomed
131 only by the router and is done once in an hour. Added `rekey'
132 field to the SilcChannelEntry in the server. Affected files
133 silcd/server.c and silcd/idlist.h.
135 * Added silc_task_unregister_by_context into the file
136 lib/silcutil/silctask.[ch].
138 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Added SILC_UMODE_GONE mode to indicate when the client is not
141 present in the SILC network. Added also support to the local
142 command AWAY that will set this mode. Added support of showing
143 "xxx is gone" in WHOIS command. The USERS command shows the
146 * Fixed setting server and router operator privileges in the
147 server's UMODE command. Affected file silcd/command.c.
149 * Merged the SKE KE1 and KE2 payloads into one payload. The
150 new KE payload is equivalent to the old KE2 payload.
152 Cleaned up the SKE Start Payload parsing. It now uses the
153 simple buffer unformatting to do the parsing. A lot faster
156 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
157 to the SKE that is used to indicate whether both of the SKE
158 parties should perform authentication. By default only the
159 responder performs authentication. By setting this flag also
160 the initiator must do authentication. By default it is unset
161 since in normal SKE case, client to server connection, only
162 the responder should do authentication. When doing SKE between
163 two clients both should perform authentication. Updated the
164 code and the protocol specs.
166 * A little fix to IDENTIFY command in the server. Search the
167 client first by hash not nickname. Affected file is
170 * Fixed the silc_client_close_connection to support closing
171 the client to client connections wihtout deleting too much
172 data. Affected file lib/silcclient/client.c.
174 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
175 are received if protocol used to be active but is not anymore
176 the application would crash due to NULL pointer dereference.
177 Affected files silcd/server.c and lib/silcclient/client.c.
179 * Added `hash' field to the SilcClientConnection to include
180 the hash function negotiated in the SKE protocol.
182 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
183 to set the channel founder authentication data. A client can
184 claim the founder rights later by providing the authentication
185 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
186 This way the channel founder can regain the channel founder
187 privileges even it is left the channel. This works only on
188 local server and the client must be connected to the same
189 server to be able to regain the founder rights. Updated the
190 protocol specs accordingly.
192 Added support to the CMODE command in the client to set the
193 founder auth data. Read the README to see how to set it.
195 Added support to the CUMODE command to claim the founder
196 rights. Read the README to see how to do it.
198 Added support for the founder authentication to the Channel
199 Entry in the server. Affected file silcd/idlist.h.
201 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
202 server's CMODE command. Affected file silcd/command.c.
204 * Added the following new functions into lib/silccore/silcauth.[ch]:
205 silc_auth_get_method and silc_auth_get_data.
207 * The server now saves the remote hosts public key to the
208 SilcIDListData pointer. Affected file silcd/protocol.c.
210 * The normal server now does not remove the channel entry from
211 the cache if the founder authentication data is set. It used
212 to remove it if the founder was the last one on the channel on
213 the server and left the channel. The auth data is saved and
214 if the channel is re-joined later the old entry is used with
215 the old auth data. Affected files silcd/command_reply.c and
218 * Removed the `pkcs' field from the SilcIDListData structure
219 in the server; it is not used. Affected file silcd/idlist.h.
221 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Fixed packet processing on slow links. Partial packets were
224 never re-processed because the incoming data buffer was cleared
225 by the application. Application must not directly clear the
226 sock->inbuf, the packet processing routines handle it. Fixed
227 this in client library and in server.
229 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Fixed the WHOIS and IDENTIFY send reply function to really
232 check whether to send list or just one entry. Affected file
235 * Cleaned up the LEAVE command's channel key distribution. The
236 affected file silcd/command.c.
238 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
239 can enforce the channel mode as well. In that case the ID
240 includes the ID of the server. The code now enforces the
241 mode change if the router have different mode than the server.
243 * The notify client operation with CMODE_CHANGE notify can now
244 return NULL client_entry pointer if the CMODE was not changed
245 by client. Application must check for this.
247 * Added <Server ID> argument to INFO command to support server
248 info fetching by Server ID.
250 * Added silc_server_announce_get_channel_users to get assembled
251 packets of channel users of the specified channel. Affected
252 file silcd/server.[ch].
254 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
255 was freed underneath the ID Cache.
257 * Re-announce clients when the server received CHANNEL_CHANGE
258 notify from the router. Affected file silcd/packet_send.c.
260 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
263 crashed since it did not handle the fact that there is no cipher
264 called "3" and didn't check the error condition. Now fixed.
266 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
267 flag. It can be used to send message requests.
269 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Implemented the RESTART command in the client.
273 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
274 notice type messages. Added notice printing to the user
277 * The channel keys are not re-generated if the channel's mode
278 is PRIVKEY, ie private key on the channel exists. Affected
279 files silcd/server.c and silcd/command.c.
281 * Fixed a little bug in channel message delivery when channel
282 private keys are set in the server. Affected file is
285 * Changed the setting on channel->on_channel = TRUE from the
286 silc_client_save_channel_key to the JOIN command reply. The
287 key payload is not received if the private channel key is set.
288 Affected file lib/silcclient/command_reply.c and the
289 lib/silcclient/client_channel.c.
291 * When the CMODE_CHANGE notify is sent and the channel private
292 key mode is removed the channel key must be re-generated in
293 other cells as well. Added this support for the router in the
294 silcd/packet_receive.c.
296 * Added new local command NOTICE to send notice message on
297 channel. Affected file silc/local_command.[ch].
299 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Added new local command ME to the client. It is used to send
302 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
303 some action. Affected file silc/local_command.[ch].
305 * Changed channel_message and private_message client operations
306 to deliver the message flags to the application. Added also
307 the `flags' arguments to the silc_client_send_channel_message
308 and silc_client_send_private_message functions. Affected file
311 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * Redefined the Private Message Payload to support private message
314 keys and to support the new private message flags. Updated
315 the protocol specs. Flags makes it possible to have for example
318 * Added new type SilcPrivateMessagePayload and defined an API
319 for it in the lib/silcclient/silcprivate.[ch].
321 * Tested private message private keys successfully. Tested the
322 private message key set, unset and list commands with the new
325 * Redefined the Channel Message Payload to include the channel
326 message flags (equal with private message flags) to support
327 for example CTCP style messages.
329 * Defined some of the message (for channel and private message)
330 flags. Updated the protocol specs and added the flags to the
331 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
333 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Added SilcKeyAgreementStatus type to the key agreement routines
336 to indicate the current status and error if one occured.
337 The status types are defined in the lib/silcclient/silcapi.h.
339 * Added new local command KEY that is used to set and unset private
340 keys for channels, set and unset private keys for private messages
341 with remote clients and to send key agreement requests and
342 negotiate the key agreement protocol with remote client. The
343 key agreement is supported only to negotiate private message keys,
344 it currently cannot be used to negotiate private keys for channels,
345 as it is not convenient for that purpose.
347 * Fixed a minor pending callback setting bug in the function
348 silc_client_get_client_by_id_resolve, now the function works.
349 Affected file lib/silcclient/idlist.c.
351 * Added function silc_net_get_local_port to get local bound
352 port by socket. Added to lib/silcutil/silcnet.[ch].
354 * Added `sockets' and `sockets_count' fields to the SilcClient
355 object. They hold the sockets of the listenning sockets in
356 the client. Listenning sockets may be for example the key
357 agreement server. Affected file lib/silcclient/client.[ch].
358 Added functions the silc_client_add_socket and the
359 silc_client_del_socket. They are exported to the application
362 * Added ~./silc/clientkeys to support other client's public keys.
364 * Renamed verify_server_key client operation to verify_public_key
365 and added one argument to indicate the type of the connection
366 (server, client etc.).
368 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Added silc_server_connection_auth_request to handle the
371 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
372 silcd/packet_receive.[ch].
374 * Added silc_server_send_connection_auth_request into the
375 silcd/packet_send.c to send the connection auth request packet.
377 * Cleaned up the silcd/protocol.c a bit and fixed some memory
380 * Fixed the public key authentication in responder side in the
381 server. The `auth_data' pointer includes the SilcPublicKey
382 not the path to the public key. Affected file silcd/protocol.c.
384 * Implemented the public key authentication in the initiator side
385 in the server. Affected file silcd/protocol.c.
387 * Removed the [RedirectClient] config section from the server
388 configuration. Is not needed and I don't want to implement it.
390 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Cleaned up the CMODE command in the server. It now works
393 correctly and supports all the modes defined in the protocol.
394 Affected file is silcd/command.c.
396 * Added `hmac_name' field to the SilcChannelEntry in the server
397 to hold the default HMAC of the channel. It can be set when
398 creating the channel (with JOIN command). Affected files
401 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
402 type to indicate the change of the current cipher and hmac
403 on the channel. Client can safely ignore the <cipher> argument
404 (if it chooses to do so) since the CHANNEL_KEY packet will
405 force the channel key change anyway. The <hmac> argument is
406 important since the client is responsible of setting the new
407 HMAC and the hmac key into use.
409 * Fixed the CMODE command in the client library as well.
411 * Tested CMODE command in router environment successfully.
413 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Show the version of the remote client (or server) when connecting
416 to the server. It is logged to the log file. Affected file
419 * Fixed the KILLED notify handling in the client library. The
420 client must be removed from all channels when receiving the
423 Also, do not remove the client entry when giving the KILL
424 command but when the KILLED notify is received.
426 * Removed silc_idlist_find_client_by_nickname from the server.
427 Not needed anymore. Affected files silcd/idlist.[ch].
429 * Implemented the CHANNEL_CHANGE notify type handling to the
430 server. Affected file silcd/server.c.
434 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added silc_server_send_notify_invite to send the INVITE
437 notify between routers.
439 * Implemented the INVITE command correctly to the server.
441 * Implemented the INVITE notify type handling in the server.
443 * Implemented the INVITE command to the client library and on the
446 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Added function silc_server_get_client_resolve to find the
449 client entry by ID from all ID lists and then resolve it
450 (using WHOIS) if it cannot be found. Affected file is
453 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Implemented the BAN command to the client library.
457 * The JOIN command in the server now checks the invite list
460 * Changed the silc_command_reply_payload_encode_va and the
461 silc_command_payload_encode_va to support that if argument is
462 NULL it ignores and checks the next argument. Affected file
463 lib/silccore/silccommand.c.
465 * Added silc_server_send_notify_ban to send the BAN notify
466 type between routers.
468 * Chaned the silc_notify_payload_encode to support that if
469 argument is NULL it ignores and checks the next argument.
470 Affected file lib/silccore/silcnotify.c.
472 * Tested ban lists in router environment successfully.
474 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Implemented BAN command to the server, in silcd/command.[ch].
478 * Removed the BAN and INVITE_LIST modes from the CMODE command
481 * Added function silc_string_match to regex match two strings.
482 Affected files lib/silcutil/silcutil.[ch].
484 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Redefined parts of the SilcChannelEntry in the server to support
487 the new ban and invite lists.
489 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
491 * Redefined the INVITE command. The same command can be used to
492 invite individuals to the channel but also to manage the invite
493 list of the channel (to add to and remove from the invite list).
494 Updated the protocol specs.
496 * Added new command SILC_COMMAND_BAN that can be used to manage
497 the ban list of the channel. Updated the protocol specs.
499 * Removed the channel modes: the SILC_CMODE_BAN and the
500 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
501 in the CMODE command. The equivalent features are now available
502 using INVITE and BAN commands. Updated the protocol specs.
504 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
505 in the network about change in the current ban list. The notify
506 type is not used by the client.
508 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
509 support the invite lists.
511 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Added new function silc_string_regexify that converts string
514 including wildcard characters into regex string that can
515 be used by the GNU regex library. Added into the file
516 lib/silcutil/silcutil.[ch].
518 Added silc_string_regex_combine to combine to regex strings
519 into one so that they can be used as one regex string by
520 the GNU regex library. Added into the file
521 lib/silcutil/silcutil.[ch].
523 Added silc_string_regex_match to match two strings. It returns
524 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
526 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Imported GNU regex to the soruce tree into lib/contrib.
529 Fixed some compiler warning from the regex.c.
531 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Fixed MOTD command in the server to work in router environment.
535 * Fixed the MOTD command in the client library to support
536 the server argument in the command.
538 * Added `nickname_len' argument to the silc_idlist_add_client
539 in the server, as the `nickname' argument may be binary data
542 * Added silc_idlist_get_channels to return all channels from
545 * Implemented LIST command to the server. Affected file is
548 * Implemented the LIST command to the client library and on the
551 * Added [<user count>] argument to the LIST command reply.
552 With private channels the user count is not shown.
554 * Updated TODO and README.
556 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * The client entry's data.registered must be TRUE even with
559 global client entry on global client list. The data.registered
560 is used to check whether the client is anymore in the network,
561 for example with WHOWAS command so it must be valid.
563 * Fixed the WHOWAS command in the server. It now actually works
564 in router environment. Added function into silcd/command_reply.c
565 silc_server_command_reply_whowas_save.
567 * Added silc_idlist_purge function to the silcd/idlist.c
568 to periodically purge the ID Cache.
570 * Fixed INFO command in the server. It works now in router
571 environment. Added <server name> argument to the INFO command
572 reply. Updated the protocol specs.
574 * Fixed minor bug in silc_idcache_purge to not purge if the
575 expire value is zero.
577 * Fixed various bugs in WHOIS and IDENTIFY command handling as
578 they were buggy because of the WHOWAS information.
580 * Fixed local command MSG to handle the async resolving of
581 the remote client properly. It used to fail the first MSG.
582 Affected file silc/local_command.c.
584 * Added `data_len' field to SilcIDCache context.
586 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Update TODO. Todo in commands in the server.
590 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
593 used by routers as broadcast packet to inform other routers
594 about the changed user mode.
596 Implemented the notify handling in the server. Affected file is
597 silcd/packet_receive.c. Added the function
598 silc_server_send_notify_umode to the silcd/packet_send.[ch].
600 * Added new generic Channel Payload and deprecated the New Channel
601 Payload. The New Channel Payload is now the generic Channel
604 * Added new argument `mode' to the silc_server_send_new_channel
605 as it is required in the Channel Payload now.
607 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
608 and created a new and real SilChannelPayload to represent the
609 new generic Channel Payload. Implemented the encode/decode
610 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
612 * Added silc_server_get_client_channel_list to return the list
613 of channels the client has joined for WHOIS command reply.
614 Affected file silcd/server.[ch].
616 * Implemented the channel list sending in the WHOIS command reply
617 in server and in the client.
619 Implemented the channel list displaying on the user interface
620 as well. Affected file silc/client_ops.c.
622 * Added silc_channel_payload_parse_list to parse list of Channel
623 Payloads. It returns SilcDList list of SilcChannelPayloads.
624 Client for example can use this function to parse the list of
625 channels it receives in the WHOIS command reply. The caller
626 must free the list by calling silc_channel_payload_list_free.
627 Affected files lib/silccore/silcchannel.[ch].
629 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added one new argument <user mode> to the WHOIS command reply
632 to return the mode of the user in SILC. Updated the protocol
635 Implemented it to the server and client.
637 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Fixed the mode printing on the user interface on joining.
640 Affected file silc/client_ops.c.
642 * Implemented the UMODE command and user modes in general to the
643 client library and to the user interface.
645 * Implemented the UMODE command to the server.
647 * The server now sends UNKNOWN_COMMAND error status if client sends
648 unknown command. Affected file silcd/command.c.
650 * All server commands now handle the command identifier the right
651 way when sending the command reply to the client. The client can
652 use to identify the command replies with the identifier.
654 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Added silc_server_get_client_route to resolve the route to
657 the client indicated by the client ID. Affected file is
660 * Added silc_server_relay_packet as general function to relay
661 packet to arbitrary destination. This deprecates functions
662 like _send_private_message_key, _relay_notify etc. Affected
663 file is silcd/packet_send.[ch].
665 Removed silc_server_send_key_agreement,
666 silc_server_send_private_message_key and
667 silc_server_packet_relay_notify functions from the file
668 silcd/packet_send.[ch].
672 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
673 server. Affected file silcd/packet_receive.[ch].
675 * Implemented the KILL command to the client. Implemented the
676 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
677 Affected files lib/silcclient/command[_reply].c and
678 lib/silcclient/client_notify.c. Implemented the KILL notify
679 printing in the user inteface.
681 * Fixed a lot silc_parse_nick memory leaks from the client
682 library in the file lib/silcclient/command.c.
684 * Changed the silc_server_send_notify_on_channels's `sender'
685 argument from SilcSocketConnection to SilcClientEntry to
686 check the sender as entry and not as connection object and not
687 to send to the client provided as argument. The affected file
688 is silcd/packet_send.[ch].
690 * The notify packets that are destined directly to the client used
691 to not to be processed by the server. Now changed that and the
692 server processes all notify packets. After relaying the packet
693 to the client the notify packet is processed in the server.
695 * The silc_server_free_client_data now checks whether there is
696 pending outgoing traffic for the client and purges the data to
697 the network before removing the client entry.
699 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
702 an client is killed from the SILC Network. Updated the protocol
705 Added new function silc_server_send_notify_killed to the
706 silcd/packet_send.[ch].
708 * Added function silc_server_packet_relay_notify to relay notify
709 packets that are destined directly to a client. In this case
710 the server does not process the notify packets but merely relays
711 it to the client. Affected file silcd/packet_send.[ch].
713 Added also silc_server_packet_process_relay_notify to check
714 whereto relay the notify. Affected file is
715 silcd/packet_receive.[ch].
717 * Implemented the KILL command to the server.
721 * Added the backup schema desgined last fall to the protocol
722 specs for everyone to see. The specification is in the
723 *-spec-xx.txt draft and the packet type definitions for the
724 backup routers is in *-pp-xx.txt draft. Thusly, added also
725 new packet type SILC_PACKET_CELL_ROUTERS.
727 * A big security problem in the implementation discovered. The
728 signoff of an client did not cause new channel key generation
729 which it of course should've done. The channel keys must be
730 always re-generated when client leaves (or signoffs) the channel.
731 The silc_server_remove_from_channels funtion now handles
732 the channel key re-generation.
734 * Added `sender' argument to the silc_server_send_notify_on_channels
735 to not to send the client provided as argument. Affected file
736 silcd/packet_send.[ch].
738 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
740 * Implemented OPER and SILCOPER commands into the server and
743 * Added silc_auth_verify and silc_auth_verify_data to verify
744 the authentication directly from the authentication payload.
745 It supports verifying both passphrase and public key based
746 authentication. Affected file lib/silccore/silcauth.[ch].
748 * Added `hash' field to the SilcIDListData structure. It is the
749 hash negotiated in the SKE protocol. Affected file is
752 * Slight redesigning of the SilcAuthPayload handling routines.
753 Do not send SilcPKCS but SilcPublicKey as argument.
755 * Implemented the public key authentication support to the
756 serverconfig. The public key is loaded from the provided path
757 and saved as authentication data to void * pointer. Thus,
758 changed the unsigned char *auth_data to void *auth_data;
760 * Fixed SHUTDOWN command to send the reply before the server
761 is shutdown. :) Affected file silcd/command.c.
763 * Fixed fatal bug in CONNECT command. The hostname was invalid
764 memory and server crashed. Affected file silcd/command.c.
766 * Fixed fatal bug in CLOSE command. The server_entry became
767 invalid but was referenced later in the command. Affected file
770 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Fixed fatal bug in failure packet handling. Server ignored
773 the failure and thus crashed when it came.
777 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
780 that the command may be executed only once in (about) 2 seconds.
781 The old SILC_CF_LAG flag is same but allows command bursts up
782 to five before limiting.
784 Added the support for CF_LAG and CF_LAG_STRICT flags to the
785 server code. Various commands now includes the CF_LAG_STRICT
786 flag to disallow any kind of miss-use of the command.
788 * Fixed the silc_buffer_unformat to not to allocate any data
789 if the length of the data is zero. It used to allocate the
790 length + 1. Affected file lib/silcutil/silcbuffmt.c.
792 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
794 * Changed the format of AdminConnection configuration section
795 in the server. Added username of the admin to the format.
796 Affected files silcd/serverconfig.[ch].
798 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
799 to return admin configuration data by host, username and/or
802 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Implemented WHOWAS command to the server. Added the functions:
806 silc_server_command_whowas_parse,
807 silc_server_command_whowas_send_reply,
808 silc_server_command_whowas_from_client and
809 silc_server_command_whowas_from_server
811 * Added <Client ID> argument to the WHOWAS command reply. Updated
812 the protocol specs accordingly.
814 * Implemented WHOWAS command and command_reply to the client
817 Implemented the WHOWAS printing on the user interface.
819 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
821 * Added new argument to the WHOWAS command reply, the real name.
822 It is an optional argument. Updated the protocol specs.
824 * Added SilcIDCacheDestructor callback that is registered when
825 the SilcIDCache is allocated. The callback is called when
826 an cache entry in the ID Cache expires, or is purged from the
827 cache. Added into lib/silccore/idcache.[ch].
829 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
830 to destruct the client entries when the cache entry expires.
831 Other ID Cache's in server and in the client library ignores
834 * If the ID Cache entry's `expire' field is zero then the entry
835 never expires. Added boolean `expire' argument to the
836 silc_idcache_add function in the lib/silccore/idcache.[ch].
837 If it is TRUE the default expiry value is used.
839 * Added silc_server_free_client_data_timeout that is registered
840 when client disconnects. By default for 5 minutes we preserve
841 the client entry for history - for WHOWAS command.
843 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Added support to the server to enforce that commands are not
846 executed more than once in 2 seconds. If server receives
847 commands from client more frequently, timeout is registered
848 to process the commands. Affected file silcd/command.c.
849 Added new function silc_server_command_process_timeout.
851 * Changed NICK_NOTIFY handling in client library to check that
852 if the client's nickname was changed, so there is no need to
853 resolve anything from the server.
855 * Removed error printing from the WHOIS and IDENTIFY commands.
856 If error occurs then it is ignored silently in the client library.
857 The application, however, may map the received error to
858 human readable error string. The application currently maps
859 the NO_SUCH_NICKNAME error to string.
861 * Made the command status message public to the application. Moved
862 them from lib/silcclient/command_reply.c to
863 lib/silcclient/command_reply.h. The application can map the
864 received command status to the string with the
865 silc_client_command_status_message function.
867 * Added check to the server to check that client's ID is same
868 as the Source ID in the packet the client sent. They must
871 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Added dist-bzip hook to the Makefile.am to make bzip2
874 compressed distributions.
876 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Server now enforces the maximum length for the nickname and
879 the channel as protocol specification dictates. 128 bytes for
880 nickname and 256 bytes for channel name.
882 * Moved the WHOIS printing to the application. The client libary
883 does not print out the WHOIS information anymore, the application
884 must do it. Renamed silc_client_command_reply_whois_print to
885 the silc_client_command_reply_whois_save.
887 The client's idle time is also sent to the application now, and
888 the idle is shown on screen.
890 * Added silc_client_command_reply_identify_save to save the
891 received IDENTIFY entries.
893 * Do not check for channel private keys in message sending and
894 reception if the channel does not have the PRIVKEY mode set.
895 Affected file lib/silclient/client_channel.c.
897 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
900 just surfaced after chaning the JOIN procedure.
902 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Added silc_client_get_clients_by_list to get client entries
905 from Client ID list, that is returned for example by JOIN
906 and USERS command replies. The application should use this
907 function for example when JOIN command reply is received to
908 resolve the clients already on the channel (library does not
909 do that anymore as USERS command reply is not used in the JOIN
910 procedure anymore). Affected files lib/silcclient/silcapi.h and
911 lib/silcclient/idlist.c.
913 * JOIN command reply and USERS command reply returns now SilcBuffer
914 pointers instead of unsigned char pointers when returning
915 the client list and mode list.
917 * Added <Client ID> argument to the JOIN command reply, mainly
918 for the server to identify for which client the command was
919 originally sent. Updated protocol specs accordingly.
921 * Added SilcDlist private_key pointer to the SilcChannelEntry
922 in the client to support the channel private keys. Affected
923 file is lib/silcclient/idlist.h.
925 * Added SilcChannelPrivateKey argument to the function
926 silc_client_send_channel_message so that application can choose
927 to use specific private ke if it wants to. If it is not provided,
928 the normal channel key is used, unless private keys are set.
929 In this case the first (key that was added first) is used
930 as the encryption key.
932 * Implemented the support for channel private key handling.
933 Implemented the following functions:
935 silc_client_add_channel_private_key,
936 silc_client_del_channel_private_keys,
937 silc_client_del_channel_private_key,
938 silc_client_list_channel_private_keys and
939 silc_client_free_channel_private_keys
941 Affected file lib/silcclient/client_channel.c.
943 * Added the support for the private keys in the channel message
944 sending and encryption and in the message reception and
945 decryption. Affected funtions are
946 silc_client_send_channel_message and silc_client_channel_message.
948 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Added SKE's key verify callback to the client library's
951 KE protocol context. Affected files lib/silcclient/protocol.[ch].
953 * Removed the statement that server (or router) must send USERS
954 command reply when joining to the channel so that the client
955 knows who are on the channel. Instead, the client list and
956 client's mode list is now sent in the JOIN command reply to the
957 client who joined channel. This is better solution.
959 * Added function silc_server_get_users_on_channel and function
960 silc_server_save_users_on_channel to the silcd/server.[ch].
962 * Removed function silc_server_command_send_users from the
965 * Do not show topic on the client library anymore. The topic is
966 sent in the command reply notify to the application and the
967 application must show the topic now.
969 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Added client searching by nickname hash into the IDENTIFY and
972 WHOIS commands in the server as they were clearly missing from
973 them. Affected file is silcd/command.c.
975 * Fixed a bug in private message receiving in the client library.
976 The remote ID was freed and it wasn't supposed, now it is
979 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Minor fix to the channel payload; allocate the data area, as it
982 needs to be of specific length.
984 * If the key agreement port is zero then the operating
985 system will define the bound port. Affected files are
986 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
988 * Added new function silc_channel_payload_decrypt into the file
989 lib/silccore/silcchannel.[ch].
991 * Moved the channel message etc, check from silc_packet_decrypt
992 to applications. The library calls now a generic
993 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
994 when the packet is either normal or special. This was done to
995 allow more wide range of checking that was not allowed when
996 the code was in library. Now applications can do virtually any
997 checks to the packet and return to the library the decision how
998 the packet should be processed. Affected files are
999 lib/silccore/silcpacket.[ch].
1001 Added silc_server_packet_decrypt_check to the server and
1002 silc_client_packet_decrypt_check to the client library.
1004 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1005 to send with specified source and destination information.
1007 * Channel message delivery between routers was broken after the
1008 channel key distribution was fixed earlier. The channel key
1009 was used be to distributed to other routers as well which is not
1010 allowed by the protocol. Now this is fixed and channel keys
1011 really are cell specific and the channel message delivery between
1012 routers comply with the protocol specification.
1014 * Fixed various commands in server to check also the global list
1015 for the channel entry and not just the local list. The affected
1016 file silcd/command.c.
1018 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Added assert()s to buffer formatting and unformatting routines
1021 to assert (if --enable-debug) when error occurs. Affected
1022 file: lib/silcutil/silcbuffmt.c.
1024 * Changed to auto-reconnect to check whether the remote host is
1025 router and register the re-connect timeout if it is. It used
1026 to check that whether we are normal server, but router must do
1027 auto-reconnect with another router as well. Affected file
1030 * Removed the [<key len>] option from CMODE command as the cipher
1031 name decides the key length, nowadays. See the defined ciphers
1032 from the protocol specification.
1034 * Added [<hmac>] option to the CMODE command to define the HMAC
1035 for the channel. Added SILC_CMODE_HMAC channel mode.
1037 * Added [<hmac>] option for the JOIN command so that user can
1038 select which HMAC is used to compute the MACs of the channel
1041 * Added Hmac field to the Channel Message Payload. The integrity
1042 of plaintext channel messages are now protected by computing
1043 MAC of the message and attaching the MAC to the payload. The
1044 MAC is encrypted. Now, it is clear that this causes some
1045 overhead to the size of the packet but rationale for this is that
1046 now the receiver can verify whether the channel message decrypted
1047 correctly and also when private keys are set for the channel the
1048 receiver can decrypt the packet with several keys and check from
1049 the MAC which key decrypted the message correctly.
1051 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1052 lib/silccrypt/silccipher.[ch].
1054 * Added silc_hash_len to return the digest length into the
1055 lib/silcrypt/silchash.[ch].
1057 * Rewrote parts of Silc Channel Payload interface in the
1058 lib/silccore/silcchannel.[ch]. The encode function now also
1059 encrypts the packet and parse function decrypts it.
1061 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Fixed a minor formatting bug in the SKE's key material processing.
1064 It actually might have processed the keys wrong way resulting
1067 * Redefined the mandatory HMAC algorithms and added new algorithms.
1068 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1069 and hmac-md5 truncated to 96 bits. The mandatory is now
1070 hmac-sha1-96. Rest are optional (including the one that used
1071 to be mandatory). Rationale for this is that the truncated HMAC
1072 length is sufficient from security point of view and can actually
1073 make the attack against the HMAC harder. Also, the truncated
1074 HMAC causes less overhead to the packets. See the RFC2104 for
1077 * Added new [hmac] configuration section. The SKE used to use
1078 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1079 is of course wrong. The official names that must be proposed in
1080 the SKE are the ones defined in the protocol specification
1081 (hmac-sha1-96 for example). The user can configure any hmac
1082 using any hash function configured in the [hash] section. At
1083 least, the mandatory must be configured.
1085 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1087 * Added HMAC list to the SKE proposal list. It has now both
1088 hash algorithm list and HMAC list. This makes the protocol
1089 incompatible with previous versions. The SKE now seems to work
1090 the way it is supposed to work, for the first time actually.
1092 * Defined plain Hash algorithms to the protocol specification.
1095 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Implemented support for key agreement packets into the server.
1098 Added functions silc_server_key_agreement and
1099 silc_server_send_key_agreement. Other than these functions,
1100 server has nothing to do with this packet.
1102 * Added support for private message key packets into the server.
1103 Added functions silc_server_private_message_key and
1104 silc_server_send_private_message_key.
1108 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1109 called in the protocol's final callback instead in the END
1110 protocol state. This makes a little more sense and in the same
1111 time in client we can use the same protocol routines for normal
1112 key exchange and to key agreement packet handling as well.
1114 * Added to both client's and server's KE protocol context the
1115 SilcSKEKeyMaterial pointer to save the key material. We will
1116 bring the key material to the protocol's final callback by doing
1117 this. The final callback must free the key material.
1119 * Added SKE's packet_send callback into client's KE protocol
1120 context so that the caller can choose what packet sending function
1121 is used. This way we can use different packet sending when
1122 doing normal SKE when doing key agreement packet handling (in
1123 the key agreement packet handling we do not want to encrypt
1126 * Implemented the responder side of the key agreement routines
1127 in the client. The client can now bind to specified port and
1128 accept incoming key negotiation. The key material is passed
1129 to the application after the protocol is over.
1131 * Implemented the processing of incoming Key Agreement packet
1132 in the client. Added function silc_client_key_agreement to
1135 * Implemented the intiator side of the key agreement routines
1136 in the client. The client can now initiate key agreement with
1137 another remote client. The key material is passed to the
1138 application after the protocol is over.
1140 * Created client_keyagr.c to include all the key agreement
1143 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1144 SILC_TASK_CALLBACK except that it is not static.
1146 * Created client_notify.c and moved the Notify packet handling
1147 from the client.[ch] into that file.
1149 * Created client_prvmsg.c and moved all private message and
1150 private message key routines from the client.[ch] into that file.
1152 * Create client_channel.c and moved all channel message and
1153 channel private key routines from the client.[ch] into that file.
1155 * Changed silc_client_get_client_by_id_resolve to resolve with
1156 WHOIS command instead of IDENTIFY command, in the file
1157 lib/silclient/idlist.c.
1159 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Implemented the SKE's responder side to the Client library.
1163 * When FAILURE is received to the protocol do not trust it
1164 blindly. Register a timeout to wait whether the remote closes
1165 the connection as it should do it, only after that process the
1166 actual failure. This was changed to both client and server.
1168 * Added client_internal.h to include some of the structures
1169 there instead of client.h in lib/silcclient/.
1171 * Added function silc_task_unregister_by_callback to unregister
1172 timeouts by the callback function.
1174 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Some "Incomplete WHOIS info" errors has been appearing on the
1177 log files. Took away the entry->userinfo check from WHOIS
1178 reply sending. The entry->userinfo is now " " if client did not
1179 provide one. I thought this was fixed earlier but something
1180 is wrong still. Let's see if the error still appears.
1182 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Fixed a minor bug in the login when the channel key is
1185 re-generated in the server. It used to generate the key in
1186 wrong order and thus caused problems in the channel traffic.
1188 * Fixed a minor bug in channel key distsribution after
1189 KICK command. The key was not sent to the router even though
1192 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added silc_ske_process_key_material_data as generic routine
1195 to process any key material as the SILC protocol dictates. The
1196 function is used by the actual SKE library but can be used by
1197 applications as well. This relates to the private message keys
1198 and the channel private keys since they must be processed the
1199 same way the normal SILC session keys. The protocol dictates
1200 this. Affected files: lib/silcske/silcske.[ch].
1202 Added also silc_ske_free_key_material to free the
1203 SilcSKEKeyMaterial structure.
1205 * Defined silc_cipher_set_key function to set the key for
1206 cipher without using the object's method function. The affected
1207 files: lib/silccrypt/silccipher.[ch].
1209 * Implemented silc silc_client_add_private_message_key,
1210 silc_client_add_private_message_key_ske,
1211 silc_client_del_private_message_key,
1212 silc_client_list_private_message_keys and
1213 silc_client_free_private_message_keys functions in the
1216 Added functions silc_client_send_private_message_key to send
1217 the Private Message Key payload and silc_client_private_message_key
1218 to handle incoming Private Message Key payload.
1220 * Added Cipher field to the Private Message Key payload to set
1221 the cipher to be used. If ignored, the default cipher defined
1222 in the SILC protocol (aes-256-cbc) is used.
1224 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Removed lib/silcclient/ops.h file.
1228 Redefined parts of the SILC Client Library API. Created new
1229 file silcapi.h that deprecates the ops.h file and defines the
1230 published Client Library API. Defined also private message key
1231 API and channel private key API into the file.
1233 This is the file that the application must include from the
1234 SILC Client Library. Other files need not be included by
1235 the application anymore.
1237 * Added new key_agreement client operation callback and also
1238 defined the Key Agreement library API for the application.
1240 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1243 is used by clients to request key negotiation between another
1244 client in the SILC network. If the negotiation is started it
1245 is performed using the SKE protocol. The result of the
1246 negotiation, the secret key material, can be used for example
1247 as private message key.
1249 Implemented the Key Agreement payload into the files
1250 lib/silccore/silauth.[ch].
1252 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Redefined ciphers for the SILC protocol. Added some new ciphers
1255 and defined the key lengths for the algorithms. Changed the
1256 code accordingly. The default key length is now 256 bits.
1258 * Fixed SKE key distribution function silc_ske_process_key_material
1259 when the key length is more than 128 bits. The default key
1260 length in SILC is now 256 bits.
1262 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1263 to indicate unsupported algorithm.
1265 * Renamed rijndael.c to aes.c and all functions as well.
1267 * Fixed a long standing channel key setting bug in client library.
1268 Weird that it has never surfaced before.
1270 * Fixed bug in channel deletion. If the entire channel is removed
1271 then it must also delete the references of the channel entry
1272 from the client's channel list as the client's channel entry and
1273 the channel's client entry share same memory.
1275 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Implemented CONNECT and SHUTDOWN commands in the client.
1279 * Implemented CLOSE command to the client.
1281 * Added the function silc_idlist_find_server_by_name into the
1282 files silcd/idlist.[ch].
1284 Added the function silc_idlist_find_server_by_conn into the
1285 files silcd/idlist.[ch].
1287 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * DIE command was renamed to SHUTDOWN. Updated the both code
1292 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1293 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1295 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1298 * Added function silc_server_create_connection function to create
1299 connection to remote router. My server implementation actually
1300 does not allow router to connect to normal server (it expects
1301 that normal server always initiates the connection to the router)
1302 so the CONNECT command is only good for connecting to another
1305 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1308 or some other client was kicked from the channel.
1310 Implemented the handling of the notify type to both client
1313 Implemented silc_server_send_notify_kicked to send the KICKED
1314 notify. It is used to send it to the server's primary router.
1316 * Implemented the KICK command into server and client.
1318 * Added `query' argument to the silc_idlist_get_client function
1319 to indicate whether to query the client from server or not if
1322 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1323 to indicate that the client is not channel founder.
1327 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Removed the rng context from SilcPacketContext structure and
1330 changed that the packet routine uses the Global RNG API.
1332 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added support for quit message that client can "leave" on the
1335 channel when it quits the SILC. It is ditributed inside the
1336 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1338 Added silc_server_free_client_data that will take the
1339 signoff message as argument.
1341 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1343 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Updated parts of the protocol specification to keep it up
1348 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1351 payloads in one packet.
1353 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1354 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1355 use now the new List flag.
1357 * Also deprecated the following packet types: REPLACE_ID,
1358 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1360 * Added list support for Notify packet in server.
1362 * Added silc_server_send_notify_channel_change to send the
1363 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1364 the silc_server_send_replace_id.
1366 * Added silc_server_send_notify_nick_change to send the
1367 NICK_CHANGE notify type. Deprecates the function
1368 silc_server_send_replace_id.
1370 * Added silc_server_send_notify_join to send the JOIN notify type.
1371 Deprecates the function silc_server_send_new_channel_user.
1373 * Added silc_server_send_notify_leave to send LEAVE notify type.
1374 Deprecates the function silc_server_send_remove_channel_user.
1376 * Added silc_server_send_notify_cmode and
1377 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1378 types. Deprecates the silc_server_send_set_mode function.
1380 * Added SERVER_SIGNOFF notify type to indicate that server has
1381 quit. This means that all clients on the channel from that
1382 server will drop. This can be also used when netsplit happens.
1384 Deprecated REMOVE_ID packet type since it is not needed anymore
1387 Added silc_server_send_notify_server_signoff to send the
1388 SERVER_SIGNOFF notify type. Deprecates the function
1389 silc_server_send_remove_id.
1391 Added also silc_server_send_notify_signoff to send the
1392 SIGNOFF notify type.
1394 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1395 SILC protocol from this day on. Changed the protocol
1396 specification as well.
1398 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1399 notify type. It is used between routers to notify about
1400 topic changes on a channel.
1402 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1405 * Partly updated the protocol specification to comply with the
1406 changes now made. It is still though a bit outdated.
1408 * The JOIN notify type now takes one extra argument <Channel ID>.
1409 The packet used to be destined to the channel but now the
1410 JOIN type may be sent as list thus it is impossible to
1411 destine it to any specific channel. By adding this argument
1412 it is again possible.
1414 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Added CREDITS file. The CHANGES and CREDITS file will appear
1417 in the distribution as well.
1419 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1422 types in the server's silcd/packet_receive.c.
1424 * Implemented CMODE and CUMODE to work in router environment.
1426 * Fixed minor encoding and decoding buglet from the
1427 lib/silccore/silcmode.c.
1429 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1432 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1434 * Changed all SilcConfigServer* and silc_config_server* to
1435 SilcServerConfig* and silc_server_config*, respectively.
1438 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Associated the ID (client or server ID) to the Authentication
1441 Payload to avoid any possibility of forging. Updated the
1442 protocol specification and the code accordingly.
1444 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * The RSA key length is now save to the RsaKey context in the
1447 key generation process in lib/silccrypt/rsa.c. The key length
1448 is now used to figure out the maximum size of the block allowed
1449 to be encrypted/signed.
1451 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1452 is equivalent to the silc_mp_mp2bin but does not allocate any
1455 * Changed silc_mp_mp2bin API to take length argument. If it is
1456 non-zero then the buffer is allocated that large. If zero, then
1457 the size is approximated using silc_mp_sizeinbase, which however
1460 * Created Global RNG API which is global RNG that application can
1461 initialize. After initializing, any routine anywhere in the
1462 code (including library) can use RNG without allocating a new
1463 RNG object. This was done to allow this sort of use of the
1464 RNG in code that has no chance to allocate RNG object. All
1465 applications currently allocate this and many routines in the
1466 library use this. Affected file lib/silccrypt/silcrng.[ch].
1468 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1469 it to use the Global RNG API.
1471 * Defined Authentication Payload into protocol specification that
1472 is used during SILC session to authenticate entities. It is
1473 used for example by client to authenticate itself to the server
1474 to obtain server operator privileges.
1476 Implemented this payload into the lib/silccore/silcauth.[ch].
1477 Implemented also routines for public key based authentication
1478 as the new protocol specification dictates.
1480 Moved definitions of different authentication methods from
1481 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1483 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1484 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1485 silc_pkcs_verify_with_hash functions into the file
1486 lib/silccrypt/silcpkcs.[ch].
1488 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * The client entry's userinfo pointer must be always valid.
1491 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1492 will fail since it requires the userinfo. Now, the userinfo
1493 is allocated as "" if actual userinfo does not exist. Actually,
1494 it must exist and it is totally Ok to drop client connections
1495 that does not announce the userinfo. However, we will make
1496 this workaround for now.
1498 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1499 to return the remote port by socket.
1501 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1504 SILC_SERVER_PENDING_EXEC and added an new macro
1505 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1506 data or when error occurs while processing the pending command.
1508 Added new argument `destructor' into silc_server_command_pending
1509 and to the SilcServerCommandPending object. This destructor is
1510 now called after calling the pending callback or if error occurs
1511 immediately. If error occurs the actual pending callback won't
1512 be called at all - only the destructor. The destructor may be
1513 NULL if destructor is not needed.
1515 All this applies for client library code as well. Similar
1516 changes were made there as well for the pending commands.
1518 In the client, the application must now allocate the
1519 SilcClientCommandContext with the silc_client_command_alloc
1522 * Added reference counter to the SilcServerCommandContext. Added
1523 function silc_server_command_alloc and silc_server_command_dup
1526 Same type of functions added to the client library for the same
1529 * Removed the cmd_ident from IDListData away since it is now
1530 global for all connections. It is the command identifier used
1531 in command sending and with pending commands. The affected file
1534 * Added reference counter to the SilcSocketConnection objecet to
1535 indicate the usage count of the object. The object won't be
1536 freed untill the reference counter hits zero. Currently only
1537 server uses this, and client ignores it. The client must be
1538 set to use this too later. The affected files are
1539 lib/silccore/silcsockconn.[ch]. Added also the function
1540 silc_socket_dup to increase the reference counter.
1542 This was mainly added because it is possible that the socket
1543 is removed underneath of pending command or other async
1544 operation. Now it won't be free'd and proper DISCONNECTING
1545 flags, etc. can be set to avoid sending data to connection that
1546 is not valid anymore.
1548 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1549 the connection. After that it sets SILC_SET_DISCONNECTED.
1550 It is, however, possible that the socket data is not still freed.
1551 The silc_server_packet_process now checks that data is not
1552 read or written to connection that is DISCONNECTED. The socket
1553 get's freed when the reference counter hits zero.
1555 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * Changed the client operation API: channel_message operation's
1558 `sender' is now the client entry of the sender, not the nickname
1559 and the `channel' is the channel entry, not the channel name.
1561 In the private_message operation the `sender' is now also the
1562 client entry of the sender not the nickname.
1564 Affected file is lib/silcclient/ops.h and all applications
1565 using the client operations.
1567 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Moved the calling of ops->connect() from connect_to_server_final
1570 into receive_new_id functin since that is the point when the
1571 client is actually allowed to send traffic to network. The
1572 affected file is lib/silcclient/client.c.
1574 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1577 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1578 (if needs broadcasting) instead of broadcasting the packets one
1579 by one which would make a burst in the network traffic.
1581 * Added `broadcast' argument to the functions in silcd/server.[ch]
1582 silc_server_create_new_channel[_with_id] to indicate whether
1583 to send New Channel packet to primary router.
1585 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Added new function into the silcd/server.[ch] files:
1588 silc_server_create_new_channel_with_id to create new channel with
1589 already existing Channel ID.
1591 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1592 lib/silccore/silcpacket.h. This packet is used t send list of
1593 Set Mode payloads inside one packet. Server uses this to set
1594 the modes for the channels and clients on those channels, that it
1595 announced to the router when it connected to it. The protocol
1596 specification has been updated accordingly.
1598 * The silc_server_new_channel did not handle the packet coming
1599 from normal server as it normally does not send that. However,
1600 when it announces its channels it does send it. Implemented
1601 the support for that.
1603 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1604 into the file lib/silccore/id.h.
1606 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Fixed memory leaks in the functions silc_idlist_del_client,
1609 silc_idlist_del_channel and silc_idlist_del_server in the file
1610 silcd/idlist.c. All of those leaked like a sieve.
1612 * Fixed some small memory leaks in the client's function
1613 silc_client_notify_by_server.
1615 * Added functions into silcd/server.c: silc_server_announce_clients,
1616 silc_server_announce_channels and silc_server_announce_server.
1617 These functions are used by normal and router server to announce
1618 to its primary router about clients, channels and servers (when
1619 router) that we own. This is done after we've connected to the
1622 These functions effectively implements the following packet types:
1623 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1624 and SILC_PACKET_NEW_ID_LIST.
1626 * Added new functions into the silcd/packet_receive.[ch]:
1627 silc_server_new_id_list, silc_server_new_channel_list and
1628 silc_server_new_channel_user_list to handle the incoming
1629 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1631 * Added support of changing Channel ID in the function
1632 silc_server_replace_id. If the server that announces a channel
1633 to the router already exists in the router (with same name but
1634 with different Channel ID), router is responsible to send
1635 Replace ID packet to the server and force the server to change
1636 the Channel ID to the one router has.
1638 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1639 client that the Channel ID has been changed by the router. The
1640 normal server sends this to the client. Client must start using
1641 the new Channel ID as the channel's ID.
1643 Implemented handling of this new type into lib/silcclient/client.c
1644 into the function silc_client_notify_by_server.
1646 * Added new function silc_idlist_replace_channel_id into the files
1647 silcd/idlist.[ch] to replace the Channel ID.
1649 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Call silc_server_command_identify_check always when processing
1652 the IDENTIFY command in silcd/command.c
1654 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1656 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1657 send keepalive packets. The packet can be sent by clients,
1658 servers and routers.
1660 Added function silc_socket_set_heartbeat into the file
1661 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1662 If not set, the heartbeat is not performed. The actual
1663 heartbeat is implemented in the low level socket connection
1664 library. However, application is responsible of actually
1667 Added silc_server_send_heartbeat to send the actual heartbeat
1668 packet into silcd/packet_send.[ch]. Server now performs
1669 keepalive with all connections.
1671 * Added silc_task_get_first function into lib/silcutil/silctask.c
1672 to return the timeout task with shortest timeout. There was a bug
1673 in task unregistration that caused problems. TODO has been
1674 updated to include that task system must be rewritten.
1676 * The client library will now resolve the client information when
1677 receiving JOIN notify from server for client that we know but
1678 have incomplete information.
1680 * Rewrote parts of silc_server_remove_from_channels and
1681 silc_server_remove_from_one_channel as they did not remove the
1682 channel in some circumstances even though they should've.
1684 * Encryption problem encountered in server:
1686 The LEAVE command used to send the Channel Key packet to the
1687 router immediately after generating it. However, the code
1688 had earlier sent Remove Channel user packet but not immediately,
1689 ie. it was put to queue. The order of packets in the router
1690 was that Channel Key packet was first and Remove Channel User
1691 packet was second, even though they were encrypted in the
1692 reverse order. For this reason, MAC check failed. Now, this
1693 is fixed by not sending the Channel Key packet immediately but
1694 putting it to queue. However, this is more fundamental problem:
1695 packets that are in queue should actually not be encrypted
1696 because packets that are sent immediately gets encrypted
1697 actually with wrong IV (and thus MAC check fails). So, packets
1698 that are in queue should be encrypted when they are sent to
1699 the wire and not when they put to the queue.
1701 However, the problem is that the current system has not been
1702 designed to work that way. Instead, the packet is encrypted
1703 as soon as possible and left to the queue. The queue is then
1704 just purged into wire. There won't be any fixes for this
1705 any time soon. So, the current semantic for packet sending
1708 o If you send packet to remote host and do not force the send
1709 (the packet will be in queue) then all subsequent packets to the
1710 same remote host must also be put to the queue. Only after the
1711 queue has been purged is it safe again to force the packet
1714 o If you send all packets immediately then it safe to send
1715 any of subsequent packets through the queue, however, after
1716 the first packet is put to queue then any subsequent packets
1717 must also be put to the queue.
1719 Follow these rules and everything works fine.
1721 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Added new function silc_server_remove_clients_by_server to
1724 remove all client entries from ID list when the server connection
1725 is lost. In this case it is also important to invalidate all
1726 client entires as they hold the invalid server entry. This
1727 fixes fatal bug when server has lost connection and will reconnect
1730 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Made some sanity checks to silc_server_daemonise like to check
1733 whether the requested user and group actually exists.
1735 * Added sanity check to SKE's silc_ske_responder_finish to check
1736 that the public and private key actually is valid.
1738 * Invalidate the client's nickname when receiving Replace ID
1739 packet and the Client ID is being replaced. This means that the
1740 server will query the nickname if someone needs it (client)
1743 * Sort the ID Cache in client library when the ID Cache data
1744 has changed (needs sorting).
1746 * Do not allow for SILC client to create several connections to
1747 several servers. The client does not support windows right now
1748 and generating multiple connections causes weird behaviour.
1750 Irssi-silc client does support windows and can handle several
1751 connections without problems, see: www.irssi.org and SILC plugin.
1753 * Fixed some places where client was added to the IDList. The
1754 rule of thumb is following (in order to get everything right):
1755 If the client is directly connected local client then the
1756 `connection' argument must be set and `router' argument must be
1757 NULL to silc_idlist_add_client function. If the client is not
1758 directly connected client then the `router' argument must
1759 bet set and the `connection' argument must be NULL to the
1760 silc_idlist_add_client function.
1762 * The funtion silc_server_packet_send_local_channel actually did
1763 not check whether the client was locally connected or not. It
1764 does that now. Fixed a bug related to LEAVE command.
1766 * Fixed Remove Channel User payload parsing bug in server's
1767 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1769 * The server's silc_server_save_channel_key now checks also the
1770 global ID list for the channel as it might not be in the local
1771 list. Fixed a bug related to LEAVE command.
1773 * Is this the end of the [<unknown>] buglet that has been lurking
1774 around for a long time? A little for loop fix in server's
1775 silc_server_command_whois_parse that is used by both IDENTIFY
1776 and WHOIS command. At least, this was a clear bug and a cause
1777 of one type of [<unknown>] buglet.
1779 * WHOIS and IDENTIFY commands call the function
1780 silc_server_command_[whois/identify]_check function even if
1781 we are not router server.
1783 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Added --with-gmp configuration option. If set the GMP
1786 is always compiled in the SILC source tree. If not set then
1787 it is checked whether the system has the GMP3 installed. If
1788 it has then the GMP won't be compiled (the system's headers
1789 and library is used), if it doesn't have it then the GMP is
1790 compiled in the SILC source tree.
1792 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Changed RSA private exponent generation to what PKCS #1
1795 suggests. We try to find the smallest possible d by doing
1796 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1797 not security fix but optimization.
1799 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Added new config entry [Identity] to fork the server and run
1802 it as specific user and group. A patch from Bostik.
1804 * Imported Dotconf configuration library into lib/dotconf.
1805 This will be used to create the SILC configuration files later.
1806 It will appear in the distsribution after this commit.
1808 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * A big code auditing weekend happening. Auditing code for
1811 obvious mistakes, bugs and errors. Also, removing any code
1814 Removed files for being obsolete:
1816 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1817 inline in the file lib/silcutil/silcbuffer.h)
1819 o lib/silcutil/silcbufutil.c (the header has inline versions)
1821 Changed code to fix possible error conditions:
1823 o The buffer formatting routines now check that the destination
1824 buffer really has enough space to add the data. This applies for
1825 both buffer formatting and unformatting
1826 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1827 unformatting was changed to accomodate following rules:
1828 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1829 sent to the function while XXX_*STRING will not allocate or copy
1830 the data into the buffer. Instead it sets the pointer from the
1831 buffer into the pointer sent as argument (XXX_*STRING used to
1832 require that the pointer must be allocated already). This change
1833 makes this whole thing a bit more consistent and more optimized
1834 (note that the data returned in the unformatting with XXX_*STRING
1835 must not be freed now). The routines return now -1 on error.
1837 o Tried to find all code that use buffer_format and buffer_unformat
1838 and added return value checking to prevent formatting and
1839 especially unformatting errors and possible subsequent fatal
1842 o Changed ske->x and ske->KEY to mallocated pointers in
1843 lib/silcske/silcske.h. Fixed possible data and memory leak.
1845 o Added return value checking to all *_parse* functions. Fixed
1846 many memory leaks as well.
1848 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1849 so that buffer overflows would not happen. All code now also
1850 checks the return value as it can fail.
1852 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Added reconnection support to server if the normal server looses
1855 its connection to the router (for example if router is rebooted).
1856 The server performs normal reconnection strategy implemented
1857 to the server. Affected file silcd/server.c.
1859 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Added new packet type SILC_PACKET_SET_MODE that is used to
1862 distribute the information about changed modes (for clients,
1863 channels and clients channel modes) to all routers in the
1864 network. Updated the protocol specification accordingly.
1866 Added functions into silcd/packet_send.c and
1867 silcd/packet_receive.c: silc_server_send_set_mode,
1868 silc_server_set_mode.
1870 Added new files silcmode.[ch] into lib/silccore that implements
1871 the encoding and decoding of Set Mode Payload. Added new type
1872 SilcSetModePayload. Moved the definitions of different modes
1873 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1875 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Oops, a little mistake in server's connection authentication
1878 protocol. The protocol is not ended with FAILURE but with
1879 SUCCESS if the authentication is Ok. :) Affected file is
1882 * Implemented NICK_CHANGE notify handling in server in the file
1883 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1884 the local clients on the channel. After the changing nickname
1885 in router environment snhould work and the [<unknown>] nickname
1886 should appear no more.
1888 The silc_server_replace_id function that receives the Replace ID
1889 payload now sends the NICK_CHANGE notify type also in the file
1890 silcd/packet_receive.c
1892 * Changed WHOIS and IDENTIFY command to support the maximum amount
1893 of arguments defined in protocol specs (3328 arguments). This
1894 fixed a bug that caused problems when there were more than three
1897 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Added extra parameter, command identifier, to the
1900 silc_client_send_command so that explicit command identifier
1903 Changed that ID list routines uses specific command identifier
1904 when sending WHOIS/IDENTIFY requests to the server so that they
1905 can be identified when the reply comes back.
1907 Affected files lib/silcclient/command.[ch],
1908 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1910 * Added `sender' argument to silc_server_packet_send_to_channel
1911 to indicaet the sender who originally sent the packet to us
1912 that we are now re-sending. Ignored if NULL. Affected file
1913 silcd/packet_send.[ch].
1915 * Added some server statistics support in silcd/server_internal.h
1916 SilcServerStatistics structure and around the server code. Also
1917 send some nice statistics information when client is connecting
1920 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Fixed channel ID decoding in server's JOIN command reply in
1923 silcd/command_reply.c
1925 * Fixed braodcasting of replace ID payload to not to send it if
1926 we are standalone server in silcd/packet_receive.c.
1928 * Fixed all channel message sending routines to not to send
1929 packets to clients that has router set, since they are routed
1930 separately in the same function earlier. Affects file
1931 silcd/packet_send.c and all channel packet sending functions.
1933 * In USERS reply, res_argv[i] are not allocated, the table
1934 is allocated. Thus changed that free the table, not its
1937 * In server's whois_check and identify_check if the client is
1938 locally connected do not send any WHOIS commands - they are not
1941 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Fixed some minor bugs in client when sending WHOIS command. The
1944 arguments was in wrong order.
1946 * Removed statis function add_to_channel from server in
1947 silcd/command.c that was previously used with the joining but
1950 * Tested USERS command in router environment successfully with two
1951 routers, two servers and two clients.
1953 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Reorganized the USERS command and command reply in client library
1956 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1957 When the command is given by user we register a pending command
1958 callback that will reprocess the command after the reply has been
1959 received from the server. When reprocessing the packet we then
1960 display the information. Thus, the USERS information is displayed
1961 now in the command callback instead of in the command reply
1962 callback. The processing of the command is same as previously
1963 when server has sent the command reply in the JOINing process.
1965 * Added to USERS command in silcd/command_reply.c to join the client,
1966 we didn't use to know about, to the channel after we've created
1967 a client entry for it. Also, for clienet we did know already still
1968 check whether it is on the channel or not and add it if not.
1970 * Removed silc_server_command_join_notify as the function and its
1973 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Changed the client's pending command handling to the same as the
1976 server's pending command handling. It is also now possible to
1977 execute command reply functions from other command reply
1978 function as the function callbacks for commands and command
1979 replies are one and same. The pending commands are not static
1980 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1981 in client connection context. Thus, pending commands are server
1982 connection specific as it is convenient.
1984 Changed the function silc_client_command_pending and
1985 silc_client_command_pending_del and added new function
1986 silc_client_command_pending_check. Removed the
1987 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1990 * Added cmd_ident, current command identifier, to the client
1991 connection context in lib/silcclient/client.h to keep track on
1992 command identifiers used in command sending. Client's command reply
1993 function handling now supports the mandatory command identifiers.
1995 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1996 funtions in client to fully support pending command callbacks.
1998 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1999 as one of the arguments to the application in the command reply
2002 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2003 before first releasing SILC but came back. Now it is removed again
2004 and should come back nomore. The FORWARDED flag was used only
2005 by the JOINing procedure by forwarding the command packet to router.
2006 Now, the JOINing procedure has been changed to more generic (due
2007 to various router environment issues) and FORWARDED is not needed
2008 anymore for anything. The protocol specification is yet to be
2011 Now, removed silc_server_packet_forward from server and the flag
2012 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2014 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Renamed NAMES command to USERS command. The NAMES was named that
2017 due to historical reasons. Now it is renamed. Also, rewrote
2018 parts of the USERS command. The nickname list is not sent anymore
2019 by the server. Only Client ID and mode lists are sent in the USERS
2020 command. Changed this also to the protocol specification.
2022 The client now resolves the names and stuff after it receives
2023 the USERS list from the server when joining to the channel.
2025 * WHOIS and IDENTIFY commands has been changed to support multiple
2026 Client ID's per command. One can now search for multiple users
2027 in the network by sending only one WHOIS or IDENTIFY command.
2028 Changed the code and the protocol specifications.
2030 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2031 uses silc_server_command_whois_parse to parse the request. */
2033 * If normal server, do not parse the WHOIS and IDENTIFY requests
2034 before sending it to the router. Saves some time.
2036 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed JOIN command on client library. Wrong number of arguments
2039 used to crash the client.
2041 * Added silc_server_channel_has_global function to check whether
2042 channel has global users or not.
2044 * Added silc_server_channel_has_local function to check whether channel
2045 has locally connected clients on the channel.
2047 * The silc_server_remove_from_one_channel now checks whether the
2048 channel has global users or not after given client was removed from
2049 the channel. It also checks whether the channel has local clients
2050 on the channel anymore. If it does not have then the channel entry
2051 is removed as it is not needed anymore.
2053 * The silc_server_notify now checks on JOIN notify whether the joining
2054 client is one of locally connected or global. If it is global then
2055 the channel has now global users on the channel and that is marked
2056 to the channel entry. Also, it now saves the global client to
2057 global list who is joining and JOINs it to the channel. This is
2058 for normal server, that is.
2060 Changed silc_server_send_notify_on_channel,
2061 silc_server_packet_relay_to_channel and
2062 silc_server_packet_send_to_channel check if we are normal server
2063 and client has router set (ie. global client) do not send the
2064 message to that client, as it is already routed to our router.
2066 * Implemented LEAVE notify type handling in silc_server_notify
2069 * Tested LEAVE command in router environment successfully. Tested
2070 with two routers, two servers and two clients.
2074 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2076 * Implemented SIGNOFF notify type handling in silc_server_notify
2079 * silc_server_remove_id now removes the client entry from all channels
2080 it has joined and thusly sends SIGNOFF notify type.
2082 * Rewrote the NAMES list generation in server by removing two excess
2083 loops. The lists are created now inside one loop.
2085 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * silc_server_remove_channel_user checks now also global list
2088 for channel and client.
2090 * silc_server_new_channel_user checks now both local and global
2091 list for channel and client. Fixed a bug in client id decoding.
2092 Used to decode wrong buffer.
2094 * silc_server_channel_message checks now both local and global
2095 list for channel entry.
2097 * Tested channel joining (hence JOIN) in router environment
2098 successfully. Tested with two routers, two servers and two
2101 * Tested channel message sending in router environment successfully.
2103 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Added silc_server_save_channel_key into server.[ch] to save the
2106 received channel key in Channel Key payload processing. It is
2107 also used in JOIN command reply handling.
2109 Equivalent function silc_client_save_channel_key added into
2110 client.[ch] into client library.
2112 * Changed JOIN command reply to send information whether the channel
2113 was created or not (is existing already) and the channel key
2114 payload. Changed protocol specs accordingly.
2116 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2117 the request was sent by ID and not by nickname. Crashed on
2120 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2123 now correctly save the received data.
2125 * silc_server_free_sock_user_data now notifies routers in the
2126 network about entities leaving the network.
2128 At the same time implemented functions silc_server_remove_id
2129 and silc_server_send_remove_id to receive and send REMOVE_ID
2130 packets. The packet is used to notify routers in the network
2131 about leaving entities. The ID removed will become invalid in
2134 * Added function silc_idlist_del_server into server. Removes and
2135 free's server entry from ID list.
2137 * silc_server_private_message function now checks, if we are router,
2138 that the destination ID really is valid ID, naturally.
2140 * In router when NEW_ID packet is received (for new client) the
2141 hash of the Client ID is saved in the ID Cache but the
2142 client->nickname is set to NULL, instead of putting the hash
2145 IDENTIFY command now also checks that client->nickname must be
2146 valid. If it is not if will request the data from the server who
2147 owns the client. Added new function
2148 silc_server_command_identify_check.
2150 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2151 to set the command to already allocated Command Payload.
2153 * Tested private message sending in router environment with two
2154 routers, two servers and two clients. Fixed minor bugs and now
2157 * Fixed segfault from client's NAMES command. Used to crash if
2160 * Forwarded packets must not be routed even if it is not destined
2161 to the receiver. Changed server code comply with this.
2163 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Added `require_reverse_mapping' boolean value to ServerParams
2166 structure. If TRUE (not default) the server will require that
2167 the connecting host has fully qualified domain name.
2169 If the reverse mapping is not required and hostname could not be
2170 found the IP address is used as hostname.
2172 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Implemented version string checking to both client and server.
2175 The check is incomplete currently due to the abnormal version
2176 strings used in development version of SILC.
2178 * Changed all command functions in server to use the new
2181 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Changed char *data to unsigned char *data in ID Cache system to
2184 support binary data as ID Cache data. Changed code to support
2185 binary data in lib/silccore/idcache.c.
2187 * Renamed silc_server_packet_relay_command_reply to
2188 silc_server_command_reply as it is normal packet receiving
2189 function. Rewrote the function to accept command replys for
2190 servers and not only for clients.
2192 * Mark remote router always as registered server if we are connecting
2193 to it. Otherwise, commands sent by the router to us are ignored.
2195 * All ID List find routines now returns the ID Cache Entry pointer
2196 as well if requested.
2198 * WHOIS command works now in router environment, tested with two
2199 routers, two servers and two clients.
2201 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2202 in router environment (as it is almost equivalent to WHOIS) but
2203 hasn't been tested thoroughly. Added new functions:
2205 silc_server_command_identify_parse
2206 silc_server_command_identify_send_reply
2207 silc_server_command_identify_from_client
2208 silc_server_command_identify_from_server
2210 * Disabled route cache adding because adding two different ID's with
2211 same IP replaces the old cache entry thus giving wrong route.
2212 The entry->router->connection is always the fastest route anyway
2213 so route cache may not be needed. Of course, new routes maybe
2214 established after receiving the ID when the entry->router->connection
2215 might not be anymore the most optimal.
2217 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Add route cache for received ID for fast routing.
2221 * Added silc_server_packet_route to route received packet on router
2222 that is not destined to us.
2224 * Renamed silc_server_get_route to silc_server_route_get.
2226 * Added id_string and id_string_len fields into SilcServer to
2227 include encoded ServerID for fast comparing without excess
2228 encoding of the ID's.
2230 * Cleaned up WHOIS command on server side. Added following static
2233 silc_server_command_whois_parse
2234 silc_server_command_whois_check
2235 silc_server_command_whois_send_reply
2236 silc_server_command_whois_from_client
2237 silc_server_command_whois_from_server
2239 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2240 arguments in command replies. All command functions should be
2241 updated to use this macro.
2243 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Minor typo fixes on command reply handling on server.
2247 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Added silc_server_command_add_to_channel internal routine to add
2250 the client to the channel after router has created the channel and
2251 sent command reply to the server.
2253 * Added generic silc_server_send_command to send any command from
2256 * Use static buffer with ID rendering instead of duplicating data.
2258 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Fixed a channel user mode bug when joining to a channel server gave
2261 everybody channel founder rights, oops.
2263 * We mark ourselves as the router of the incoming server connection
2264 if we are router ourselves. This way we can check in some packet
2265 sending functions whether it is locally connected server. For
2266 incoming router connections we put NULL.
2268 * For router sending packets locally means now always sending the
2269 packet cell wide; to local clients and local servers. For normal
2270 server sending packet locally means sending it to only local
2273 * Fixed the JOIN command to really work in router environment. If the
2274 channel is created it is always created by the router. Router is
2275 also responsible of making the initial joining to the channel,
2276 sending JOIN notify to the sending server and distributing
2277 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2278 does not exist server doesn't do anything else but forward the
2279 command to the router which performs everything.
2281 * Added silc_server_send_channel_key function to send the Channel Key
2284 * Added silc_server_create_channel_key to create new channel key. The
2285 channel key is now re-generated everytime someone joins or leaves
2286 a channel, as protocol dictates. Note: channel->key_len is the
2289 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2292 packet_receive.[ch] to separate packet sending and receiving
2293 routines. The server.[ch] now includes everything else including
2294 actual packet processing (writing and reading data) and other
2297 Renamed silc_server_private_message_send_internal to
2298 silc_server_send_private_message. The routine is still though
2299 used only to relay private messages as server does not send
2300 private messages itself.
2302 Renamed silc_server_new_channel to silc_server_create_new_channel
2303 and added new function sicl_server_new_channel that handles the
2304 incoming New Channel packet. Added also new sending function
2305 silc_server_send_new_channel to send New Channel Payload.
2307 * Added new function silc_server_notify to process incoming notify
2308 packet to the server/router. Server may then relay the notify
2309 to clients if needed.
2311 * Added new function silc_server_new_channel_user to process incoming
2312 New Channel User packet. Router will redistribute the packet and
2313 send JOIN notify to its local clients and locally connected servers
2314 if needed. Normal server will send JOIN notify to its local client
2315 on same channel when received this packet. Added also corresponding
2316 sending function silc_server_send_new_channel_user to sent the
2319 * Added boolean route argument to send_notif_to_channel and
2320 packet_send_to_channel functions to attempt to route the packet
2321 if it is TRUE and send only locally if it is FALSE.
2323 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * silc_server_replace_id now broadcasts the received replace ID
2326 packet if it is not broadcast packet already. The router must
2327 broadcast to inform other routers about changed ID.
2329 * Added backpointer to server's router into SilcServer context in
2330 silcd/server_internal.h.
2332 * Fixed silc_server_packet_broadcast to send correct broadcast
2335 * The channel key is now distributed to the local client as soon
2336 as it is received from the router (in router environment) so that
2337 no other packet may be sent for the channel until client has
2340 * silc_server_remove_channel_user now broadcasts the received
2341 Remove Channel User packet if it is not broadcast packet already.
2342 The router must broadcast to inform other routers about removed
2345 * Added users field into SilcPacketContext that is a reference count
2346 of the context. One can increase the reference count by calling
2347 silc_packet_context_dup which is now changed to just increase the
2348 reference count instead of duplicating the data. The reference
2349 count is decresed by calling silc_packet_context_free that will
2350 free the data after the reference count hits zero.
2352 For now on the packet context and everything allocated into it
2353 (including the raw packet from network) must be freed by calling
2354 the new silc_packet_context_free function. Added also new function
2355 silc_packet_context_alloc that must be used now to allocate the
2356 context. This also means that if a routine is asynchronous from
2357 silc_[client/server]_packet_parse_type the packet context must
2358 be duplicated by calling silc_packet_context_dup. Otherwise it
2359 gets free'd after silc_[client/server]_packet_parse_type returns.
2360 Also, one must remember that if packet is duplicated then its
2361 reference count must be decresed by calling the free function as
2362 many times as it was duplicated.
2364 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2365 from both client and server.
2367 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Made joining to a channel working in router environment.
2371 * Cleaned up JOIN command on server side and create function
2372 silc_server_command_join_channel internal routine to make the
2375 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Changed silc_command_pending list to SilcDList. Also, added
2378 `ident' field to SilcServerCommandPending structure to identify
2379 the reply and to call correct callback.
2381 Added silc_server_command_pending_check function to replace the
2382 corresnponding macro. The silc_command_pending list is not
2385 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2386 to set identifier to previously allocated Command Payload. It
2387 is used to set identifier for command when resending Command
2390 * Added silc_command_payload_encode_payload to encode Command
2391 Payload buffer from SilcCommandPayload structure.
2393 * Added silc_argument_payload_encode_payload to encode Argument
2394 payload buffer from SilcArgumentPayload structure.
2396 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Changed WHOIS command to support router connection on server side.
2399 The whois request is always sent to router unless the server is
2400 standalone server. After server has received the reply from the
2401 router will it send the reply to the client.
2403 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2404 broadcast received broadcast packet. The function is used only
2405 by router. The broadcast packet is always sent to the router's
2408 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2409 render given ID to printable string, for log files for example.
2411 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Made basic router to router connections working. At least they
2414 can now connect to each other but nothing really works the way
2415 they are supposed - yet.
2417 * Added new initiator token to RouterConnection configuration
2418 file in silcd/serverconfig.[ch]. It is used to tell whether we
2419 are the initiator to the remote router or whether we'll expect
2420 the other end to connect.
2422 * Moved registering of listener task to silc_server_init, hence
2423 the server starts listenning as soon as it is run, even if it
2424 does not have connections to other routers. Let's see how well
2427 * Changed default connection retry timeouts for more suitable in
2430 * Removed cipher and such arguments from silc_idlist_add_client
2431 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2432 Added new function silc_idlist_add_data to add the keys and stuff
2435 * Added SilcIDListData structure and added it to SilcClientEntry
2436 and SilcServerEntry as their first field in the structure. This
2437 way we can explicitly cast the ID entries to the SilcIDListData
2438 structure and get common data for the entries. In past, we had
2439 to first check what type of connection it is and then cast it to
2440 correct ID entry type. Now, we can directly cast the opaque
2441 pointer to the SilcIDListData (no matter what ID entry it actually
2442 is) and get the data needed.
2444 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2447 in some circumstances even if threre were timeout tasks, though not
2448 IO tasks, but tasks anyway. Now fixed.
2450 * Defined SilcServerConnection structure to hold connection specific
2451 stuff about directly connected servers and routers. The definition
2452 is currently in silcd/server_internal.h. I thought about having
2453 a bit more important role fro this struct but for now it is used
2454 only when connecting to other server (or router actually).
2456 * Added connecting retry support in server when connecting to
2457 router(s). The retry feature implement exponential backoff
2458 algorithm. Also, added SilcServerParams structure to hold default
2459 parameters for server. For now, it include these retry settings
2460 and are hard coded. After server is moded to be as Silc Server
2461 Library this structure will be more important.
2463 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Changed client librarys channel->clients table to SilcList and
2466 changed code accordingly.
2468 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Changed client's channel table to SilcList and changed code
2471 accordingly. Also changed SilcChannelClientEntry to include back-
2472 pointer to the channel so that client entry can use that structure
2473 as list as well and we have fast cross-reference to the channel.
2474 This change dramatically decreased the complexity of channel
2475 handling with client entry and vice versa (removed one extra
2476 loop when searching for channel entry from many functions).
2478 * Changed server->sim from table to SilcDList and changed code
2481 * NAMES command can now be used from user interface. It will show
2482 the user list on the channel, neatly.
2484 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2485 Code now saves realname of the user if it becomes available.
2487 * Renamed configure.in to configure.in.pre and made ./prepare
2488 script to automatically add correct version string to
2489 configure.in which it creates from configure.in.pre.
2491 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * NAMES command reply now shows users mode with the nickname when
2496 * Moved silc_client_ch[u]mode[_char] functions from
2497 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2498 place sucks, they are utility functions and should be in some
2501 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2503 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2506 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Added TRQ (efficient deque and list library) into lib/trq. This is
2511 a very good list library that is currently used in the SILC. Defined
2512 SilcList API over the library because I didn't like the API very
2513 much. See lib/trq/silclist.h for the API and examples of how to
2514 use the API. Fixed various places in the code to use the new
2515 SilcList API. The SilcList is meant for lists that has a structure
2516 already defined as a list. It is not suitable to add just some
2517 context to the list (in TRQ, the context is the list actually).
2519 So, I defined SilcDList that can be used for the purpose where
2520 predefined list structure does not exit. This can be used as
2521 such list. Now some context just can be added to the SilcDList.
2522 Currently this list is not used in the SILC just yet, though there
2523 are a lot places where this can replace dynamically allocated
2524 tables and I will fix these places, later, to use SilcDList.
2525 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2526 and use TRQ internally).
2528 Also fixed some annoying warning messages that the original TRQ
2529 code generated. Also minor changes to TRQ's Makefile.in.
2531 * Added support for querying by Client ID to both WHOIS and
2532 IDENTIFY commands into server, as required by the protocol.
2534 * Removed method function pointers from SilcBuffer structure. They
2535 weren't used to anything and just increased the context size for
2536 no good reason. This change also made silc_buffer_alloc and
2537 silc_buffer_free functions inline functions.
2539 * Disabled command flooding detection support until it's fixed so
2540 that it accepts commands in but does not execute them more than once
2543 * Added silc_net_localhost(), to return local hostname, into
2544 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2545 that must be initialized before calling silc_client_init.
2547 * Added new function: silc_server_send_notify_on_channels to send
2548 notify messages to all channels client has joined. It is assured
2549 that the message is sent only once per client.
2551 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2552 lib/silcutil/silcutil.[ch] as silc_format function. The new
2553 function is generic and is used by server as well, not only by
2554 the logging routines.
2556 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2557 the provided version string was not acceptable. Added new function:
2558 silc_ske_check_version into lib/silcske/silcske.h. The function
2559 must be implemented by the application (client or server) and it
2560 does not reside in the SKE library. The function checks the version
2561 string remote end sent.
2563 * Added back pointers (to opaque context and to SilcSocketConnection)
2564 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2566 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2567 duplicate packet context structure.
2569 * Changed `notify' client operation to send same arguments as client
2570 receives from server except for ID's. ID's are mapped to correct
2571 ID entry and that is returned. Also, if channel entry is not sent
2572 by server but the notify is for channel the channel entry is sent
2573 to application (otherwise application doesn't know that it is for
2574 channel (library gets it from packet's Destination ID)).
2576 * Added silc_client_remove_from_channels into client library to
2577 remove a client from all channels it has joined to. Used when
2578 received SIGNOFF notify from server. Added also new function
2579 silc_client_replace_from_channels to replace old ID entry with
2580 new ID entry on all channels. Used when received NICK_CHANGE
2583 * Fixed ID Cache list handling in silc_idlist_get_client in
2584 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2585 to get (or query) client by ID.
2587 * Updated TODO list.
2589 * Added connection authentication status message defined by the
2590 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2591 support for these into the code in client and server side.
2593 * Added generic function silc_client_send_command to send any command
2594 with variable argument list. Application should use this function
2595 to send commands if the command functions provided by the library
2596 does not suite for the application's user interface needs.
2598 * Added new `failure' client operation. Application is notified about
2599 received failure packet if client is executing a protocol. In this
2600 case the protocol's execution has failed.
2602 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2603 is required by the protocol.
2605 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2606 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2609 * Added status flag to SilcSKE object to indicate realtime status
2610 of the SKE protocol.
2612 * Application receives now exactly same command reply arguments as
2613 the library receives from server. However, if ID is received the
2614 corresponding ID entry is returned to the application (eg. Client
2615 ID is mapped to correct SilcClientEntry entry and that is returned).
2616 Changed command_reply client operation due to this change.
2618 * Changed all ID's in commands and in command replys as ID Payloads.
2619 Change affected both client and server side codes.
2621 All ID's sent in SILC network (with execption of ID's in SILC
2622 Packet header) are sent in ID Payload to support variable length
2625 * Server now notifies nick changes and notifies all clients on
2626 the channels about the new nickname (about the new Client ID,
2629 * Implemented CMODE command to change channel modes. Supports all
2630 channel modes defined by the protocol specs except ban and invite
2631 lists. (Also, private channel key mode is supported but support for
2632 setting private channel key in client is missing, thus, this mode
2633 has no effect on client side (except that server requires that the
2634 client uses private channel key and normal channel traffic does not
2637 Also, invite mode works per se, but INVITE command does not work
2638 yet correctly, so you can set channel as invite only channel but
2639 inviting clients to the channel does not work (it is yet to be
2640 thought what's the best way to do it).
2642 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2643 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2644 Implemented CUMODE command to change user's mode on the channel.
2645 Supports all modes defined by the protocol specs.
2647 * Added NAMES command reply to return users modes on the channel.
2649 * Removed unnecessary and slow ciphers from lib/silccrypt.
2651 * Set SO_KEEPALIVE option to connection sockets by default.
2653 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2655 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2656 redefined the Notify Payload into protocol specs.
2658 * Added silc_id_payload_parse_id to get ID directly from raw
2661 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2664 accept searching by Client ID as well.
2666 * Added support for LEAVE and SIGNOFF notify types in client library.
2668 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2669 to parse ID Payload from raw data.
2671 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Added flags parameter into silc_ske_assemble_security_properties
2674 function in lib/silcske/silcske.[ch].
2676 * Changed notify client operation to fit better for notify messages
2677 sent by server. The notify payload received from server is now
2678 passed to the application (after parsing it to SilcNotifyPayload).
2679 It is application's responsibility to retrieve the arguments
2680 from the payload and show the message the way it wants. The message
2681 sent by server is implementation specific.
2683 * Changed public keys to comply with the protocol specification.
2684 Old public keys are not supported anymore and are not compatible.
2686 * Removed nickname from Channel Payload as the latest draft removed
2687 it. The client must resolve the nickname from the NAMES command
2688 reply received when it joined the channel.
2690 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2692 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Fixed some errors in protocol specification drafts.
2696 * Created lib/silccore/silcnotify.c to implement Notify Payload
2697 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2698 generic payloads described by protocol specifications. The file
2699 includes implementations for ID Payload and Argument Payload.
2701 * Changed Command Payload implementation to use the new Argument
2702 Payload. Changed command_xxxx_payload to command_payload_xxxx
2703 to comply with SILC coding conventions.
2705 * Added suppport for Argument Payload handling in Notify Payload
2706 implementation as protocol requires it. Added the new support
2707 into server and client lib as well.
2709 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Added support for multiple nicknames on same channel. [n] is
2712 added locally to the nickname if there are more than one same
2713 nicknames on the channel.
2715 * Server now sends all nicknames that matched WHOIS request.
2716 Client also shows the list received from server.
2718 * Added TOPIC command to client side. User can now set and show
2719 current topic on channel.
2721 * Added MOTD command to client and server. Also, server sends the
2722 motd when client connects to the server.
2724 * Changed version strings to comply ISO 8601.
2726 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Fixed protocol error handling in client library. It should now
2729 cope even if the SKE fails for some reason.
2731 * Made new protocol specification drafts for submitting to IETF.
2733 * Implemented TOPIC command to server in silcd/command.c.
2735 * Added two new notify types into lib/silccore/silcnotify.h:
2736 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2737 notify nickname change and topic setting/change on a channel.
2739 * API change of command_reply operation in client library. The
2740 application gets now the status type received from server as well.
2742 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2746 * Cras fixed and optimized the packet handling even further and
2747 it should work now. Minor change to the prototype of function
2748 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2750 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Added new function into lib/silcutil/silcschedule.[ch]:
2753 silc_schedule_with_fd to select() a specified fd. The function
2754 returns after timeout expires or data arrives or goes. The
2755 function is used by packet routines to wait that all data is
2756 received from network.
2758 * Fixed data reading from network in lib/silccore/silcpacket.c.
2759 The code now assures that all data is read from the fd and then
2760 continues packet processing. This was a bug fix since the code
2761 used to drop some data in some circumstances.
2763 * Added new function into lib/silcclient/client.[ch]:
2764 silc_client_start_key_exchange to start key exchange after
2765 connection has been established to server. The code internally
2766 now uses this funtion but its main purpose was to provide it
2767 for applications that perform their own connecting. After
2768 application has created a connection it merely calls this
2769 function to start the key exchange between client and server.
2770 The library takes care of everything else after that.
2772 Updated also lib/silcclient/README to explain the usage of
2775 * Do not send to application information that connection has
2776 been established. Application gets notified it by connect
2779 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Applied cras's patch to add silc_schedule_one function. The
2782 function runs scheduler once and returns.
2784 * Fixed the scheduler after cras messed it up. The timeout
2785 handling works now as it's supposed to work.
2787 * Added into lib/silccore/ silcnotify.h to include notify
2788 message types support. Changed silc_server_send_notify*
2789 functions, in server.[ch], to support those new notify types.
2790 Added the support for the notify types into client library,
2791 as well. Added new notify client operation into ops.h in
2794 * Changed silc_server_packet_send_to_channel to send normal
2795 packets instead of just channel message packets. The function
2796 is now used to send the notify packets to channels. It is not
2797 used to send channel message packets anymore, as server never
2800 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2801 va_arg()s as it seems to require it nowadays. I guess, if SILC
2802 is compiled with older va_arg() the new code should work anyway.
2804 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Splitted core library. Core library (lib/silccore) includes
2807 now only SILC protocol specific core (and common) components.
2808 Created new utility library (lib/silcutil) that includes more
2809 generic purpose stuff. The stuff for util library was taken
2810 from the old core library. This was minor and easy split.
2812 * Created SILC Client Library (lib/silcclient) that includes
2813 implementation of the SILC client without user interface. This
2814 was major move from silc/ directory. The code has been changed
2815 so that it is transparent towards the user interface. The
2816 silc/ directory includes now the same user interface as before
2817 and it uses the new client library. Read lib/silcclient/README.
2818 Basicly, the client library performs everything else related
2819 to SILC except user interface handling. Also, configuration
2820 files are considered to be part of user interface and library
2821 does not handle them.
2823 This change also changed a lot of structures, function naming etc.
2824 Most important change was that SilcClientWindow object was
2825 renamed to SilcClientConnection in the client library. Created
2826 also new file lib/silcclient/ops.h. Also added new files
2827 silc/local_command.[ch] and silc/client_ops.[ch].
2829 All these changes were made to make it easier for user interface
2830 designers to create what ever user interface for the SILC client
2833 It is also expected that the server will be moved to lib
2834 directory as well and SILC Server Library will be created;
2835 sometimes in the future.
2837 * Removed Local commands from lib/silccore/silccommand.h as
2838 they are application specific and new client library does not
2839 handle any of those anymore.
2841 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2842 old client implementation in silc/.
2844 * Added support for callback functions in SILC_LOG_* macros.
2845 Application can now set its own callbacks that will be called
2846 instead of using the default functions that will always print
2847 the debug messages to stderr (or stdout). Also, debugging can
2848 now be disabled by setting silc_debug to FALSE and re-enabled by
2849 setting it to TRUE. Note, that logging will still work even
2850 if debugging is disabled.
2852 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2853 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2854 silc_log_reset_debug_callbacks.
2856 * To enable debugging in silc client one must give now -d
2857 option on command line.
2859 * Changed silc_schedule_init to automatically allocate task queues
2860 if they are not allocated before calling it.
2862 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Added GMP 3.1 into math library.
2866 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2869 a channel in SILC network. The packet is used by servers and
2870 routers to notify other routers that user has left a channel.
2871 This little feature was missing until now. Added the feature
2872 to protocol specification as well.
2874 Added functions: silc_server_send_remove_channel_user and
2875 silc_server_remove_channel_user into server.[ch].
2877 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2878 lib/silccore/silcpacket.h. However, they are not implemented
2881 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Fixed joining to a channel and sending channel messages
2884 between server and router. The channel message sending should
2885 now work inside a cell.
2887 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Fixed the private message sending between server and router.
2890 The private message sending should now work inside a cell.
2892 * Added silc_server_replace_id into server.[ch] to replace
2893 existing ID in the SILC network.
2895 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2896 and silc_idlist_replace_server_id into idlist.[ch] in server.
2898 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Fixed the server to server connections. Server can again now
2901 connect to router. Router to router connections probably does
2904 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Added dynamic protocol registering support. Now protocols can
2907 registered and unregistered on the fly. Patch by cras.
2909 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Added lib/contrib directory to hold routines that some platforms
2912 don't have but are needed by SILC.
2914 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2915 into lin/contrib to provide getopt() and getopt_long() for
2916 those who don't have it.
2918 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Added AWAY command to client. When away message is set and
2921 client receives a private message packet the client automatically
2922 replies to the sender with the away message.
2924 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2925 bug seemed to be the cause of recent problems when compiling
2928 * Added version detection support to SKE protocol specification
2929 and added the new changes to the SKE implementation as well.
2930 There were other minor changes in the SKE protocol as well.
2932 Many changes in lib/silcske/silcske.[ch] and in
2933 lib/silcske/payload.[ch].
2935 * Added ^U functionality, clear input line. Patch from cras.
2937 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Mainly small bugfixes on core library. Fixed some debugging
2940 logging and buffer overflow in silclog.c.
2942 * Updated config.sub and config.guess on the distribution tree.
2944 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Added command lagging support in server. Client may execute
2947 commands now only once in two seconds.
2949 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Optimized packet reception. MAC computation and checking is now
2952 also more optimized. A lot previously duplicated code is now
2953 used as generic by both client and server.
2955 * Fixed key pair generation in clientutil.c
2957 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added into lib/silccore/silcbufutil.[ch] new function;
2960 silc_buffer_realloc.
2962 * Moved generic packet sending/encryption functions to
2963 lib/silccore/silcpacket.[ch] from client and server. Some
2964 rewriting of the functions.
2966 * Moved all generic packet reception/decryption functions to
2967 lib/silccore/silcpacket.[ch] from client and server. The
2968 packet processing is now much cleaner in both client and server.
2969 These were major changes in both client and server.
2971 * Created many common functions in server to do packet sending.
2972 Previously code were duplicated a lot, this has been removed
2975 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Rewrote major parts of the ID cache system. Don't know
2978 whether it is better now or not but at least the API is more
2981 * Major rewrite on ID cache stuff on client because of the ID
2982 cache API changes. Added idlist.c to client.
2984 * Also major rewrite on ID cache stuff on server as well.
2985 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2986 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2987 in hand, instead they are all put into the ID cache system now.
2988 All server_idlist_* routines uses ID cache now instead of
2989 traversing its own lists (those lists does not exist anymore).
2990 SilcIDList though still exists. Also, SilcXXXEntry's are
2993 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Finally made the SKE implementation compliant to the protocol
2996 specification. All mp integers are now binary encoded as
2997 opposed being HEX encoded.
2999 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3002 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3003 functions: silc_[encode/decode]_pem. Also added function
3004 silc_encode_pem_file to PEM encode with newlines ('\n') for
3007 * SILC public keys are now encoded either PEM or binary. Same
3008 option is for private keys as well. By default private keys
3009 are binary encoded and public keys PEM encoded. Silly HEX
3010 encoding were removed.
3012 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3013 function to create fingerprints.
3015 * Fixed a bug in SHA1; does not change the original data anymore.
3017 * Partly implemented INFO command on client and server side.
3018 Fixed CLEAR command. Changes to SERVER command; show current
3019 server(s) when giving command without arguments. Added
3020 VERSION command to client.
3022 * Added check to server that unregistered connections cannot
3023 execute commands (unless it is specificly allowed).
3025 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Fixed screen refresh.
3029 * Fixed channel joining bug from client. On some circumstances
3030 client tried to join to a channel it had already joined.
3032 * Added public key verification process into client's protocol.c.
3033 The client now verifies the public key from user and saves
3034 it into ~./silc/serverkeys/ directory.
3036 Added into: clientutil.[ch]: silc_client_verify_server_key.
3038 * Changed SKE protocol's silc_ske_initiator_finish function
3039 to accept callback function that verifies the received public
3040 key. Removed old silc_ske_verify_public_key function.
3042 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3045 silc_pkcs_private_key[_data]_set.
3047 * Made the password and public authentication more cleaner in
3048 server's protocol.c.
3050 * Removed historic and obsolete protocol `channel_auth' from
3051 both client and server.
3053 * Removed wrong way of sending command status messages from
3054 server to client in server's command.c. The old way violated
3055 protocol specification.
3057 Changes to silccore/silccommand.[ch]: removed
3058 silc_command_encode_status_payload -> not needed anymore,
3059 changed silc_command_encode_payload_va to accept extra
3060 argument on variable argument list. The argument type must
3061 now be provided to the function. Also, added new function:
3062 silc_command_encode_reply_payload_va which is same as
3063 normal command_encode_payload_va except command status type
3064 is provided as extra argument.
3066 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Added ~./silc directory handling. The directory includes the
3069 public and private keys for the client.
3071 Added silc_client_check_silc_dir, silc_client_create_identifier
3072 and silc_client_load_keys.
3074 * Implemented SILC protocol compliant public key. Added public
3075 and private key saving to and loading from files.
3077 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3078 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3079 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3080 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3081 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3083 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3084 silc_pkcs_load_[public/private]_key.
3086 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Added silc_server_get_route (route.[ch]) to get connection
3089 data for the fastest route for given ID.
3091 * Implemented INVITE command on client and server. The command
3092 were re-defined in the SILC Protocol Specification and the
3093 implementation now complies with the specification.
3095 * Implemented PING command on client and server.
3097 * Implemented NAMES command on client and server. The server side
3098 supports currently only normal server not router server yet.
3099 Some changes to NAMES definition in SILC protocol specification.
3101 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Implemented LEAVE command on client and server.
3105 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3106 again. This change was made to the protocol as well. Server
3107 should not violate the protocol specification anymore.
3109 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3112 was tested. SOCKS4 was not but should work anyway.
