3 * Fixed packet processing on slow links. Partial packets were
4 never re-processed because the incoming data buffer was cleared
5 by the application. Application must not directly clear the
6 sock->inbuf, the packet processing routines handle it. Fixed
7 this in client library and in server.
9 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Fixed the WHOIS and IDENTIFY send reply function to really
12 check whether to send list or just one entry. Affected file
15 * Cleaned up the LEAVE command's channel key distribution. The
16 affected file silcd/command.c.
18 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
19 can enforce the channel mode as well. In that case the ID
20 includes the ID of the server. The code now enforces the
21 mode change if the router have different mode than the server.
23 * The notify client operation with CMODE_CHANGE notify can now
24 return NULL client_entry pointer if the CMODE was not changed
25 by client. Application must check for this.
27 * Added <Server ID> argument to INFO command to support server
28 info fetching by Server ID.
30 * Added silc_server_announce_get_channel_users to get assembled
31 packets of channel users of the specified channel. Affected
32 file silcd/server.[ch].
34 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
35 was freed underneath the ID Cache.
37 * Re-announce clients when the server received CHANNEL_CHANGE
38 notify from the router. Affected file silcd/packet_send.c.
40 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
43 crashed since it did not handle the fact that there is no cipher
44 called "3" and didn't check the error condition. Now fixed.
46 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
47 flag. It can be used to send message requests.
49 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Implemented the RESTART command in the client.
53 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
54 notice type messages. Added notice printing to the user
57 * The channel keys are not re-generated if the channel's mode
58 is PRIVKEY, ie private key on the channel exists. Affected
59 files silcd/server.c and silcd/command.c.
61 * Fixed a little bug in channel message delivery when channel
62 private keys are set in the server. Affected file is
65 * Changed the setting on channel->on_channel = TRUE from the
66 silc_client_save_channel_key to the JOIN command reply. The
67 key payload is not received if the private channel key is set.
68 Affected file lib/silcclient/command_reply.c and the
69 lib/silcclient/client_channel.c.
71 * When the CMODE_CHANGE notify is sent and the channel private
72 key mode is removed the channel key must be re-generated in
73 other cells as well. Added this support for the router in the
74 silcd/packet_receive.c.
76 * Added new local command NOTICE to send notice message on
77 channel. Affected file silc/local_command.[ch].
79 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added new local command ME to the client. It is used to send
82 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
83 some action. Affected file silc/local_command.[ch].
85 * Changed channel_message and private_message client operations
86 to deliver the message flags to the application. Added also
87 the `flags' arguments to the silc_client_send_channel_message
88 and silc_client_send_private_message functions. Affected file
91 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * Redefined the Private Message Payload to support private message
94 keys and to support the new private message flags. Updated
95 the protocol specs. Flags makes it possible to have for example
98 * Added new type SilcPrivateMessagePayload and defined an API
99 for it in the lib/silcclient/silcprivate.[ch].
101 * Tested private message private keys successfully. Tested the
102 private message key set, unset and list commands with the new
105 * Redefined the Channel Message Payload to include the channel
106 message flags (equal with private message flags) to support
107 for example CTCP style messages.
109 * Defined some of the message (for channel and private message)
110 flags. Updated the protocol specs and added the flags to the
111 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
113 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Added SilcKeyAgreementStatus type to the key agreement routines
116 to indicate the current status and error if one occured.
117 The status types are defined in the lib/silcclient/silcapi.h.
119 * Added new local command KEY that is used to set and unset private
120 keys for channels, set and unset private keys for private messages
121 with remote clients and to send key agreement requests and
122 negotiate the key agreement protocol with remote client. The
123 key agreement is supported only to negotiate private message keys,
124 it currently cannot be used to negotiate private keys for channels,
125 as it is not convenient for that purpose.
127 * Fixed a minor pending callback setting bug in the function
128 silc_client_get_client_by_id_resolve, now the function works.
129 Affected file lib/silcclient/idlist.c.
131 * Added function silc_net_get_local_port to get local bound
132 port by socket. Added to lib/silcutil/silcnet.[ch].
134 * Added `sockets' and `sockets_count' fields to the SilcClient
135 object. They hold the sockets of the listenning sockets in
136 the client. Listenning sockets may be for example the key
137 agreement server. Affected file lib/silcclient/client.[ch].
138 Added functions the silc_client_add_socket and the
139 silc_client_del_socket. They are exported to the application
142 * Added ~./silc/clientkeys to support other client's public keys.
144 * Renamed verify_server_key client operation to verify_public_key
145 and added one argument to indicate the type of the connection
146 (server, client etc.).
148 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Added silc_server_connection_auth_request to handle the
151 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
152 silcd/packet_receive.[ch].
154 * Added silc_server_send_connection_auth_request into the
155 silcd/packet_send.c to send the connection auth request packet.
157 * Cleaned up the silcd/protocol.c a bit and fixed some memory
160 * Fixed the public key authentication in responder side in the
161 server. The `auth_data' pointer includes the SilcPublicKey
162 not the path to the public key. Affected file silcd/protocol.c.
164 * Implemented the public key authentication in the initiator side
165 in the server. Affected file silcd/protocol.c.
167 * Removed the [RedirectClient] config section from the server
168 configuration. Is not needed and I don't want to implement it.
170 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Cleaned up the CMODE command in the server. It now works
173 correctly and supports all the modes defined in the protocol.
174 Affected file is silcd/command.c.
176 * Added `hmac_name' field to the SilcChannelEntry in the server
177 to hold the default HMAC of the channel. It can be set when
178 creating the channel (with JOIN command). Affected files
181 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
182 type to indicate the change of the current cipher and hmac
183 on the channel. Client can safely ignore the <cipher> argument
184 (if it chooses to do so) since the CHANNEL_KEY packet will
185 force the channel key change anyway. The <hmac> argument is
186 important since the client is responsible of setting the new
187 HMAC and the hmac key into use.
189 * Fixed the CMODE command in the client library as well.
191 * Tested CMODE command in router environment successfully.
193 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Show the version of the remote client (or server) when connecting
196 to the server. It is logged to the log file. Affected file
199 * Fixed the KILLED notify handling in the client library. The
200 client must be removed from all channels when receiving the
203 Also, do not remove the client entry when giving the KILL
204 command but when the KILLED notify is received.
206 * Removed silc_idlist_find_client_by_nickname from the server.
207 Not needed anymore. Affected files silcd/idlist.[ch].
209 * Implemented the CHANNEL_CHANGE notify type handling to the
210 server. Affected file silcd/server.c.
214 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

217 notify between routers.
219 * Implemented the INVITE command correctly to the server.
221 * Implemented the INVITE notify type handling in the server.
223 * Implemented the INVITE command to the client library and on the
226 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
228 * Added function silc_server_get_client_resolve to find the
229 client entry by ID from all ID lists and then resolve it
230 (using WHOIS) if it cannot be found. Affected file is
233 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Implemented the BAN command to the client library.
237 * The JOIN command in the server now checks the invite list
240 * Changed the silc_command_reply_payload_encode_va and the
241 silc_command_payload_encode_va to support that if argument is
242 NULL it ignores and checks the next argument. Affected file
243 lib/silccore/silccommand.c.
245 * Added silc_server_send_notify_ban to send the BAN notify
246 type between routers.
248 * Chaned the silc_notify_payload_encode to support that if
249 argument is NULL it ignores and checks the next argument.
250 Affected file lib/silccore/silcnotify.c.
252 * Tested ban lists in router environment successfully.
254 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Implemented BAN command to the server, in silcd/command.[ch].
258 * Removed the BAN and INVITE_LIST modes from the CMODE command
261 * Added function silc_string_match to regex match two strings.
262 Affected files lib/silcutil/silcutil.[ch].
264 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Redefined parts of the SilcChannelEntry in the server to support
267 the new ban and invite lists.
269 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Redefined the INVITE command. The same command can be used to
272 invite individuals to the channel but also to manage the invite
273 list of the channel (to add to and remove from the invite list).
274 Updated the protocol specs.
276 * Added new command SILC_COMMAND_BAN that can be used to manage
277 the ban list of the channel. Updated the protocol specs.
279 * Removed the channel modes: the SILC_CMODE_BAN and the
280 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
281 in the CMODE command. The equivalent features are now available
282 using INVITE and BAN commands. Updated the protocol specs.
284 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
285 in the network about change in the current ban list. The notify
286 type is not used by the client.
288 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
289 support the invite lists.
291 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Added new function silc_string_regexify that converts string
294 including wildcard characters into regex string that can
295 be used by the GNU regex library. Added into the file
296 lib/silcutil/silcutil.[ch].
298 Added silc_string_regex_combine to combine to regex strings
299 into one so that they can be used as one regex string by
300 the GNU regex library. Added into the file
301 lib/silcutil/silcutil.[ch].
303 Added silc_string_regex_match to match two strings. It returns
304 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
306 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Imported GNU regex to the soruce tree into lib/contrib.
309 Fixed some compiler warning from the regex.c.
311 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * Fixed MOTD command in the server to work in router environment.
315 * Fixed the MOTD command in the client library to support
316 the server argument in the command.
318 * Added `nickname_len' argument to the silc_idlist_add_client
319 in the server, as the `nickname' argument may be binary data
322 * Added silc_idlist_get_channels to return all channels from
325 * Implemented LIST command to the server. Affected file is
328 * Implemented the LIST command to the client library and on the
331 * Added [<user count>] argument to the LIST command reply.
332 With private channels the user count is not shown.
334 * Updated TODO and README.
336 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
338 * The client entry's data.registered must be TRUE even with
339 global client entry on global client list. The data.registered
340 is used to check whether the client is anymore in the network,
341 for example with WHOWAS command so it must be valid.
343 * Fixed the WHOWAS command in the server. It now actually works
344 in router environment. Added function into silcd/command_reply.c
345 silc_server_command_reply_whowas_save.
347 * Added silc_idlist_purge function to the silcd/idlist.c
348 to periodically purge the ID Cache.
350 * Fixed INFO command in the server. It works now in router
351 environment. Added <server name> argument to the INFO command
352 reply. Updated the protocol specs.
354 * Fixed minor bug in silc_idcache_purge to not purge if the
355 expire value is zero.
357 * Fixed various bugs in WHOIS and IDENTIFY command handling as
358 they were buggy because of the WHOWAS information.
360 * Fixed local command MSG to handle the async resolving of
361 the remote client properly. It used to fail the first MSG.
362 Affected file silc/local_command.c.
364 * Added `data_len' field to SilcIDCache context.
366 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Update TODO. Todo in commands in the server.
370 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
373 used by routers as broadcast packet to inform other routers
374 about the changed user mode.
376 Implemented the notify handling in the server. Affected file is
377 silcd/packet_receive.c. Added the function
378 silc_server_send_notify_umode to the silcd/packet_send.[ch].
380 * Added new generic Channel Payload and deprecated the New Channel
381 Payload. The New Channel Payload is now the generic Channel
384 * Added new argument `mode' to the silc_server_send_new_channel
385 as it is required in the Channel Payload now.
387 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
388 and created a new and real SilChannelPayload to represent the
389 new generic Channel Payload. Implemented the encode/decode
390 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
392 * Added silc_server_get_client_channel_list to return the list
393 of channels the client has joined for WHOIS command reply.
394 Affected file silcd/server.[ch].
396 * Implemented the channel list sending in the WHOIS command reply
397 in server and in the client.
399 Implemented the channel list displaying on the user interface
400 as well. Affected file silc/client_ops.c.
402 * Added silc_channel_payload_parse_list to parse list of Channel
403 Payloads. It returns SilcDList list of SilcChannelPayloads.
404 Client for example can use this function to parse the list of
405 channels it receives in the WHOIS command reply. The caller
406 must free the list by calling silc_channel_payload_list_free.
407 Affected files lib/silccore/silcchannel.[ch].
409 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Added one new argument <user mode> to the WHOIS command reply
412 to return the mode of the user in SILC. Updated the protocol
415 Implemented it to the server and client.
417 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Fixed the mode printing on the user interface on joining.
420 Affected file silc/client_ops.c.
422 * Implemented the UMODE command and user modes in general to the
423 client library and to the user interface.
425 * Implemented the UMODE command to the server.
427 * The server now sends UNKNOWN_COMMAND error status if client sends
428 unknown command. Affected file silcd/command.c.
430 * All server commands now handle the command identifier the right
431 way when sending the command reply to the client. The client can
432 use to identify the command replies with the identifier.
434 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added silc_server_get_client_route to resolve the route to
437 the client indicated by the client ID. Affected file is
440 * Added silc_server_relay_packet as general function to relay
441 packet to arbitrary destination. This deprecates functions
442 like _send_private_message_key, _relay_notify etc. Affected
443 file is silcd/packet_send.[ch].
445 Removed silc_server_send_key_agreement,
446 silc_server_send_private_message_key and
447 silc_server_packet_relay_notify functions from the file
448 silcd/packet_send.[ch].
452 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
453 server. Affected file silcd/packet_receive.[ch].
455 * Implemented the KILL command to the client. Implemented the
456 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
457 Affected files lib/silcclient/command[_reply].c and
458 lib/silcclient/client_notify.c. Implemented the KILL notify
459 printing in the user inteface.
461 * Fixed a lot silc_parse_nick memory leaks from the client
462 library in the file lib/silcclient/command.c.
464 * Changed the silc_server_send_notify_on_channels's `sender'
465 argument from SilcSocketConnection to SilcClientEntry to
466 check the sender as entry and not as connection object and not
467 to send to the client provided as argument. The affected file
468 is silcd/packet_send.[ch].
470 * The notify packets that are destined directly to the client used
471 to not to be processed by the server. Now changed that and the
472 server processes all notify packets. After relaying the packet
473 to the client the notify packet is processed in the server.
475 * The silc_server_free_client_data now checks whether there is
476 pending outgoing traffic for the client and purges the data to
477 the network before removing the client entry.
479 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
482 an client is killed from the SILC Network. Updated the protocol
485 Added new function silc_server_send_notify_killed to the
486 silcd/packet_send.[ch].
488 * Added function silc_server_packet_relay_notify to relay notify
489 packets that are destined directly to a client. In this case
490 the server does not process the notify packets but merely relays
491 it to the client. Affected file silcd/packet_send.[ch].
493 Added also silc_server_packet_process_relay_notify to check
494 whereto relay the notify. Affected file is
495 silcd/packet_receive.[ch].
497 * Implemented the KILL command to the server.
501 * Added the backup schema desgined last fall to the protocol
502 specs for everyone to see. The specification is in the
503 *-spec-xx.txt draft and the packet type definitions for the
504 backup routers is in *-pp-xx.txt draft. Thusly, added also
505 new packet type SILC_PACKET_CELL_ROUTERS.
507 * A big security problem in the implementation discovered. The
508 signoff of an client did not cause new channel key generation
509 which it of course should've done. The channel keys must be
510 always re-generated when client leaves (or signoffs) the channel.
511 The silc_server_remove_from_channels funtion now handles
512 the channel key re-generation.
514 * Added `sender' argument to the silc_server_send_notify_on_channels
515 to not to send the client provided as argument. Affected file
516 silcd/packet_send.[ch].
518 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Implemented OPER and SILCOPER commands into the server and
523 * Added silc_auth_verify and silc_auth_verify_data to verify
524 the authentication directly from the authentication payload.
525 It supports verifying both passphrase and public key based
526 authentication. Affected file lib/silccore/silcauth.[ch].
528 * Added `hash' field to the SilcIDListData structure. It is the
529 hash negotiated in the SKE protocol. Affected file is
532 * Slight redesigning of the SilcAuthPayload handling routines.
533 Do not send SilcPKCS but SilcPublicKey as argument.
535 * Implemented the public key authentication support to the
536 serverconfig. The public key is loaded from the provided path
537 and saved as authentication data to void * pointer. Thus,
538 changed the unsigned char *auth_data to void *auth_data;
540 * Fixed SHUTDOWN command to send the reply before the server
541 is shutdown. :) Affected file silcd/command.c.
543 * Fixed fatal bug in CONNECT command. The hostname was invalid
544 memory and server crashed. Affected file silcd/command.c.
546 * Fixed fatal bug in CLOSE command. The server_entry became
547 invalid but was referenced later in the command. Affected file
550 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Fixed fatal bug in failure packet handling. Server ignored
553 the failure and thus crashed when it came.
557 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
560 that the command may be executed only once in (about) 2 seconds.
561 The old SILC_CF_LAG flag is same but allows command bursts up
562 to five before limiting.
564 Added the support for CF_LAG and CF_LAG_STRICT flags to the
565 server code. Various commands now includes the CF_LAG_STRICT
566 flag to disallow any kind of miss-use of the command.
568 * Fixed the silc_buffer_unformat to not to allocate any data
569 if the length of the data is zero. It used to allocate the
570 length + 1. Affected file lib/silcutil/silcbuffmt.c.
572 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Changed the format of AdminConnection configuration section
575 in the server. Added username of the admin to the format.
576 Affected files silcd/serverconfig.[ch].
578 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
579 to return admin configuration data by host, username and/or
582 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * Implemented WHOWAS command to the server. Added the functions:
586 silc_server_command_whowas_parse,
587 silc_server_command_whowas_send_reply,
588 silc_server_command_whowas_from_client and
589 silc_server_command_whowas_from_server
591 * Added <Client ID> argument to the WHOWAS command reply. Updated
592 the protocol specs accordingly.
594 * Implemented WHOWAS command and command_reply to the client
597 Implemented the WHOWAS printing on the user interface.
599 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Added new argument to the WHOWAS command reply, the real name.
602 It is an optional argument. Updated the protocol specs.
604 * Added SilcIDCacheDestructor callback that is registered when
605 the SilcIDCache is allocated. The callback is called when
606 an cache entry in the ID Cache expires, or is purged from the
607 cache. Added into lib/silccore/idcache.[ch].
609 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
610 to destruct the client entries when the cache entry expires.
611 Other ID Cache's in server and in the client library ignores
614 * If the ID Cache entry's `expire' field is zero then the entry
615 never expires. Added boolean `expire' argument to the
616 silc_idcache_add function in the lib/silccore/idcache.[ch].
617 If it is TRUE the default expiry value is used.
619 * Added silc_server_free_client_data_timeout that is registered
620 when client disconnects. By default for 5 minutes we preserve
621 the client entry for history - for WHOWAS command.
623 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Added support to the server to enforce that commands are not
626 executed more than once in 2 seconds. If server receives
627 commands from client more frequently, timeout is registered
628 to process the commands. Affected file silcd/command.c.
629 Added new function silc_server_command_process_timeout.
631 * Changed NICK_NOTIFY handling in client library to check that
632 if the client's nickname was changed, so there is no need to
633 resolve anything from the server.
635 * Removed error printing from the WHOIS and IDENTIFY commands.
636 If error occurs then it is ignored silently in the client library.
637 The application, however, may map the received error to
638 human readable error string. The application currently maps
639 the NO_SUCH_NICKNAME error to string.
641 * Made the command status message public to the application. Moved
642 them from lib/silcclient/command_reply.c to
643 lib/silcclient/command_reply.h. The application can map the
644 received command status to the string with the
645 silc_client_command_status_message function.
647 * Added check to the server to check that client's ID is same
648 as the Source ID in the packet the client sent. They must
651 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * Added dist-bzip hook to the Makefile.am to make bzip2
654 compressed distributions.
656 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
658 * Server now enforces the maximum length for the nickname and
659 the channel as protocol specification dictates. 128 bytes for
660 nickname and 256 bytes for channel name.
662 * Moved the WHOIS printing to the application. The client libary
663 does not print out the WHOIS information anymore, the application
664 must do it. Renamed silc_client_command_reply_whois_print to
665 the silc_client_command_reply_whois_save.
667 The client's idle time is also sent to the application now, and
668 the idle is shown on screen.
670 * Added silc_client_command_reply_identify_save to save the
671 received IDENTIFY entries.
673 * Do not check for channel private keys in message sending and
674 reception if the channel does not have the PRIVKEY mode set.
675 Affected file lib/silclient/client_channel.c.
677 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
680 just surfaced after chaning the JOIN procedure.
682 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Added silc_client_get_clients_by_list to get client entries
685 from Client ID list, that is returned for example by JOIN
686 and USERS command replies. The application should use this
687 function for example when JOIN command reply is received to
688 resolve the clients already on the channel (library does not
689 do that anymore as USERS command reply is not used in the JOIN
690 procedure anymore). Affected files lib/silcclient/silcapi.h and
691 lib/silcclient/idlist.c.
693 * JOIN command reply and USERS command reply returns now SilcBuffer
694 pointers instead of unsigned char pointers when returning
695 the client list and mode list.
697 * Added <Client ID> argument to the JOIN command reply, mainly
698 for the server to identify for which client the command was
699 originally sent. Updated protocol specs accordingly.
701 * Added SilcDlist private_key pointer to the SilcChannelEntry
702 in the client to support the channel private keys. Affected
703 file is lib/silcclient/idlist.h.
705 * Added SilcChannelPrivateKey argument to the function
706 silc_client_send_channel_message so that application can choose
707 to use specific private ke if it wants to. If it is not provided,
708 the normal channel key is used, unless private keys are set.
709 In this case the first (key that was added first) is used
710 as the encryption key.
712 * Implemented the support for channel private key handling.
713 Implemented the following functions:
715 silc_client_add_channel_private_key,
716 silc_client_del_channel_private_keys,
717 silc_client_del_channel_private_key,
718 silc_client_list_channel_private_keys and
719 silc_client_free_channel_private_keys
721 Affected file lib/silcclient/client_channel.c.
723 * Added the support for the private keys in the channel message
724 sending and encryption and in the message reception and
725 decryption. Affected funtions are
726 silc_client_send_channel_message and silc_client_channel_message.
728 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Added SKE's key verify callback to the client library's
731 KE protocol context. Affected files lib/silcclient/protocol.[ch].
733 * Removed the statement that server (or router) must send USERS
734 command reply when joining to the channel so that the client
735 knows who are on the channel. Instead, the client list and
736 client's mode list is now sent in the JOIN command reply to the
737 client who joined channel. This is better solution.
739 * Added function silc_server_get_users_on_channel and function
740 silc_server_save_users_on_channel to the silcd/server.[ch].
742 * Removed function silc_server_command_send_users from the
745 * Do not show topic on the client library anymore. The topic is
746 sent in the command reply notify to the application and the
747 application must show the topic now.
749 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Added client searching by nickname hash into the IDENTIFY and
752 WHOIS commands in the server as they were clearly missing from
753 them. Affected file is silcd/command.c.
755 * Fixed a bug in private message receiving in the client library.
756 The remote ID was freed and it wasn't supposed, now it is
759 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Minor fix to the channel payload; allocate the data area, as it
762 needs to be of specific length.
764 * If the key agreement port is zero then the operating
765 system will define the bound port. Affected files are
766 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
768 * Added new function silc_channel_payload_decrypt into the file
769 lib/silccore/silcchannel.[ch].
771 * Moved the channel message etc, check from silc_packet_decrypt
772 to applications. The library calls now a generic
773 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
774 when the packet is either normal or special. This was done to
775 allow more wide range of checking that was not allowed when
776 the code was in library. Now applications can do virtually any
777 checks to the packet and return to the library the decision how
778 the packet should be processed. Affected files are
779 lib/silccore/silcpacket.[ch].
781 Added silc_server_packet_decrypt_check to the server and
782 silc_client_packet_decrypt_check to the client library.
784 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
785 to send with specified source and destination information.
787 * Channel message delivery between routers was broken after the
788 channel key distribution was fixed earlier. The channel key
789 was used be to distributed to other routers as well which is not
790 allowed by the protocol. Now this is fixed and channel keys
791 really are cell specific and the channel message delivery between
792 routers comply with the protocol specification.
794 * Fixed various commands in server to check also the global list
795 for the channel entry and not just the local list. The affected
796 file silcd/command.c.
798 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Added assert()s to buffer formatting and unformatting routines
801 to assert (if --enable-debug) when error occurs. Affected
802 file: lib/silcutil/silcbuffmt.c.
804 * Changed to auto-reconnect to check whether the remote host is
805 router and register the re-connect timeout if it is. It used
806 to check that whether we are normal server, but router must do
807 auto-reconnect with another router as well. Affected file
810 * Removed the [<key len>] option from CMODE command as the cipher
811 name decides the key length, nowadays. See the defined ciphers
812 from the protocol specification.
814 * Added [<hmac>] option to the CMODE command to define the HMAC
815 for the channel. Added SILC_CMODE_HMAC channel mode.
817 * Added [<hmac>] option for the JOIN command so that user can
818 select which HMAC is used to compute the MACs of the channel
821 * Added Hmac field to the Channel Message Payload. The integrity
822 of plaintext channel messages are now protected by computing
823 MAC of the message and attaching the MAC to the payload. The
824 MAC is encrypted. Now, it is clear that this causes some
825 overhead to the size of the packet but rationale for this is that
826 now the receiver can verify whether the channel message decrypted
827 correctly and also when private keys are set for the channel the
828 receiver can decrypt the packet with several keys and check from
829 the MAC which key decrypted the message correctly.
831 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
832 lib/silccrypt/silccipher.[ch].
834 * Added silc_hash_len to return the digest length into the
835 lib/silcrypt/silchash.[ch].
837 * Rewrote parts of Silc Channel Payload interface in the
838 lib/silccore/silcchannel.[ch]. The encode function now also
839 encrypts the packet and parse function decrypts it.
841 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Fixed a minor formatting bug in the SKE's key material processing.
844 It actually might have processed the keys wrong way resulting
847 * Redefined the mandatory HMAC algorithms and added new algorithms.
848 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
849 and hmac-md5 truncated to 96 bits. The mandatory is now
850 hmac-sha1-96. Rest are optional (including the one that used
851 to be mandatory). Rationale for this is that the truncated HMAC
852 length is sufficient from security point of view and can actually
853 make the attack against the HMAC harder. Also, the truncated
854 HMAC causes less overhead to the packets. See the RFC2104 for
857 * Added new [hmac] configuration section. The SKE used to use
858 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
859 is of course wrong. The official names that must be proposed in
860 the SKE are the ones defined in the protocol specification
861 (hmac-sha1-96 for example). The user can configure any hmac
862 using any hash function configured in the [hash] section. At
863 least, the mandatory must be configured.
865 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
867 * Added HMAC list to the SKE proposal list. It has now both
868 hash algorithm list and HMAC list. This makes the protocol
869 incompatible with previous versions. The SKE now seems to work
870 the way it is supposed to work, for the first time actually.
872 * Defined plain Hash algorithms to the protocol specification.
875 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Implemented support for key agreement packets into the server.
878 Added functions silc_server_key_agreement and
879 silc_server_send_key_agreement. Other than these functions,
880 server has nothing to do with this packet.
882 * Added support for private message key packets into the server.
883 Added functions silc_server_private_message_key and
884 silc_server_send_private_message_key.
888 * Changed the silc_[client|server]_protocol_ke_set_keys to be
889 called in the protocol's final callback instead in the END
890 protocol state. This makes a little more sense and in the same
891 time in client we can use the same protocol routines for normal
892 key exchange and to key agreement packet handling as well.
894 * Added to both client's and server's KE protocol context the
895 SilcSKEKeyMaterial pointer to save the key material. We will
896 bring the key material to the protocol's final callback by doing
897 this. The final callback must free the key material.
899 * Added SKE's packet_send callback into client's KE protocol
900 context so that the caller can choose what packet sending function
901 is used. This way we can use different packet sending when
902 doing normal SKE when doing key agreement packet handling (in
903 the key agreement packet handling we do not want to encrypt
906 * Implemented the responder side of the key agreement routines
907 in the client. The client can now bind to specified port and
908 accept incoming key negotiation. The key material is passed
909 to the application after the protocol is over.
911 * Implemented the processing of incoming Key Agreement packet
912 in the client. Added function silc_client_key_agreement to
915 * Implemented the intiator side of the key agreement routines
916 in the client. The client can now initiate key agreement with
917 another remote client. The key material is passed to the
918 application after the protocol is over.
920 * Created client_keyagr.c to include all the key agreement
923 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
924 SILC_TASK_CALLBACK except that it is not static.
926 * Created client_notify.c and moved the Notify packet handling
927 from the client.[ch] into that file.
929 * Created client_prvmsg.c and moved all private message and
930 private message key routines from the client.[ch] into that file.
932 * Create client_channel.c and moved all channel message and
933 channel private key routines from the client.[ch] into that file.
935 * Changed silc_client_get_client_by_id_resolve to resolve with
936 WHOIS command instead of IDENTIFY command, in the file
937 lib/silclient/idlist.c.
939 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Implemented the SKE's responder side to the Client library.
943 * When FAILURE is received to the protocol do not trust it
944 blindly. Register a timeout to wait whether the remote closes
945 the connection as it should do it, only after that process the
946 actual failure. This was changed to both client and server.
948 * Added client_internal.h to include some of the structures
949 there instead of client.h in lib/silcclient/.
951 * Added function silc_task_unregister_by_callback to unregister
952 timeouts by the callback function.
954 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Some "Incomplete WHOIS info" errors has been appearing on the
957 log files. Took away the entry->userinfo check from WHOIS
958 reply sending. The entry->userinfo is now " " if client did not
959 provide one. I thought this was fixed earlier but something
960 is wrong still. Let's see if the error still appears.
962 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Fixed a minor bug in the login when the channel key is
965 re-generated in the server. It used to generate the key in
966 wrong order and thus caused problems in the channel traffic.
968 * Fixed a minor bug in channel key distsribution after
969 KICK command. The key was not sent to the router even though
972 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Added silc_ske_process_key_material_data as generic routine
975 to process any key material as the SILC protocol dictates. The
976 function is used by the actual SKE library but can be used by
977 applications as well. This relates to the private message keys
978 and the channel private keys since they must be processed the
979 same way the normal SILC session keys. The protocol dictates
980 this. Affected files: lib/silcske/silcske.[ch].
982 Added also silc_ske_free_key_material to free the
983 SilcSKEKeyMaterial structure.
985 * Defined silc_cipher_set_key function to set the key for
986 cipher without using the object's method function. The affected
987 files: lib/silccrypt/silccipher.[ch].
989 * Implemented silc silc_client_add_private_message_key,
990 silc_client_add_private_message_key_ske,
991 silc_client_del_private_message_key,
992 silc_client_list_private_message_keys and
993 silc_client_free_private_message_keys functions in the
996 Added functions silc_client_send_private_message_key to send
997 the Private Message Key payload and silc_client_private_message_key
998 to handle incoming Private Message Key payload.
1000 * Added Cipher field to the Private Message Key payload to set
1001 the cipher to be used. If ignored, the default cipher defined
1002 in the SILC protocol (aes-256-cbc) is used.
1004 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Removed lib/silcclient/ops.h file.
1008 Redefined parts of the SILC Client Library API. Created new
1009 file silcapi.h that deprecates the ops.h file and defines the
1010 published Client Library API. Defined also private message key
1011 API and channel private key API into the file.
1013 This is the file that the application must include from the
1014 SILC Client Library. Other files need not be included by
1015 the application anymore.
1017 * Added new key_agreement client operation callback and also
1018 defined the Key Agreement library API for the application.
1020 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1023 is used by clients to request key negotiation between another
1024 client in the SILC network. If the negotiation is started it
1025 is performed using the SKE protocol. The result of the
1026 negotiation, the secret key material, can be used for example
1027 as private message key.
1029 Implemented the Key Agreement payload into the files
1030 lib/silccore/silauth.[ch].
1032 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Redefined ciphers for the SILC protocol. Added some new ciphers
1035 and defined the key lengths for the algorithms. Changed the
1036 code accordingly. The default key length is now 256 bits.
1038 * Fixed SKE key distribution function silc_ske_process_key_material
1039 when the key length is more than 128 bits. The default key
1040 length in SILC is now 256 bits.
1042 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1043 to indicate unsupported algorithm.
1045 * Renamed rijndael.c to aes.c and all functions as well.
1047 * Fixed a long standing channel key setting bug in client library.
1048 Weird that it has never surfaced before.
1050 * Fixed bug in channel deletion. If the entire channel is removed
1051 then it must also delete the references of the channel entry
1052 from the client's channel list as the client's channel entry and
1053 the channel's client entry share same memory.
1055 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Implemented CONNECT and SHUTDOWN commands in the client.
1059 * Implemented CLOSE command to the client.
1061 * Added the function silc_idlist_find_server_by_name into the
1062 files silcd/idlist.[ch].
1064 Added the function silc_idlist_find_server_by_conn into the
1065 files silcd/idlist.[ch].
1067 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * DIE command was renamed to SHUTDOWN. Updated the both code
1072 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1073 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1075 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1078 * Added function silc_server_create_connection function to create
1079 connection to remote router. My server implementation actually
1080 does not allow router to connect to normal server (it expects
1081 that normal server always initiates the connection to the router)
1082 so the CONNECT command is only good for connecting to another
1085 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1088 or some other client was kicked from the channel.
1090 Implemented the handling of the notify type to both client
1093 Implemented silc_server_send_notify_kicked to send the KICKED
1094 notify. It is used to send it to the server's primary router.
1096 * Implemented the KICK command into server and client.
1098 * Added `query' argument to the silc_idlist_get_client function
1099 to indicate whether to query the client from server or not if
1102 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1103 to indicate that the client is not channel founder.
1107 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Removed the rng context from SilcPacketContext structure and
1110 changed that the packet routine uses the Global RNG API.
1112 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Added support for quit message that client can "leave" on the
1115 channel when it quits the SILC. It is ditributed inside the
1116 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1118 Added silc_server_free_client_data that will take the
1119 signoff message as argument.
1121 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1123 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Updated parts of the protocol specification to keep it up
1128 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1131 payloads in one packet.
1133 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1134 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1135 use now the new List flag.
1137 * Also deprecated the following packet types: REPLACE_ID,
1138 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1140 * Added list support for Notify packet in server.
1142 * Added silc_server_send_notify_channel_change to send the
1143 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1144 the silc_server_send_replace_id.
1146 * Added silc_server_send_notify_nick_change to send the
1147 NICK_CHANGE notify type. Deprecates the function
1148 silc_server_send_replace_id.
1150 * Added silc_server_send_notify_join to send the JOIN notify type.
1151 Deprecates the function silc_server_send_new_channel_user.
1153 * Added silc_server_send_notify_leave to send LEAVE notify type.
1154 Deprecates the function silc_server_send_remove_channel_user.
1156 * Added silc_server_send_notify_cmode and
1157 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1158 types. Deprecates the silc_server_send_set_mode function.
1160 * Added SERVER_SIGNOFF notify type to indicate that server has
1161 quit. This means that all clients on the channel from that
1162 server will drop. This can be also used when netsplit happens.
1164 Deprecated REMOVE_ID packet type since it is not needed anymore
1167 Added silc_server_send_notify_server_signoff to send the
1168 SERVER_SIGNOFF notify type. Deprecates the function
1169 silc_server_send_remove_id.
1171 Added also silc_server_send_notify_signoff to send the
1172 SIGNOFF notify type.
1174 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1175 SILC protocol from this day on. Changed the protocol
1176 specification as well.
1178 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1179 notify type. It is used between routers to notify about
1180 topic changes on a channel.
1182 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1185 * Partly updated the protocol specification to comply with the
1186 changes now made. It is still though a bit outdated.
1188 * The JOIN notify type now takes one extra argument <Channel ID>.
1189 The packet used to be destined to the channel but now the
1190 JOIN type may be sent as list thus it is impossible to
1191 destine it to any specific channel. By adding this argument
1192 it is again possible.
1194 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Added CREDITS file. The CHANGES and CREDITS file will appear
1197 in the distribution as well.
1199 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1201 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1202 types in the server's silcd/packet_receive.c.
1204 * Implemented CMODE and CUMODE to work in router environment.
1206 * Fixed minor encoding and decoding buglet from the
1207 lib/silccore/silcmode.c.
1209 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1212 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1214 * Changed all SilcConfigServer* and silc_config_server* to
1215 SilcServerConfig* and silc_server_config*, respectively.
1218 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Associated the ID (client or server ID) to the Authentication
1221 Payload to avoid any possibility of forging. Updated the
1222 protocol specification and the code accordingly.
1224 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * The RSA key length is now save to the RsaKey context in the
1227 key generation process in lib/silccrypt/rsa.c. The key length
1228 is now used to figure out the maximum size of the block allowed
1229 to be encrypted/signed.
1231 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1232 is equivalent to the silc_mp_mp2bin but does not allocate any
1235 * Changed silc_mp_mp2bin API to take length argument. If it is
1236 non-zero then the buffer is allocated that large. If zero, then
1237 the size is approximated using silc_mp_sizeinbase, which however
1240 * Created Global RNG API which is global RNG that application can
1241 initialize. After initializing, any routine anywhere in the
1242 code (including library) can use RNG without allocating a new
1243 RNG object. This was done to allow this sort of use of the
1244 RNG in code that has no chance to allocate RNG object. All
1245 applications currently allocate this and many routines in the
1246 library use this. Affected file lib/silccrypt/silcrng.[ch].
1248 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1249 it to use the Global RNG API.
1251 * Defined Authentication Payload into protocol specification that
1252 is used during SILC session to authenticate entities. It is
1253 used for example by client to authenticate itself to the server
1254 to obtain server operator privileges.
1256 Implemented this payload into the lib/silccore/silcauth.[ch].
1257 Implemented also routines for public key based authentication
1258 as the new protocol specification dictates.
1260 Moved definitions of different authentication methods from
1261 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1263 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1264 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1265 silc_pkcs_verify_with_hash functions into the file
1266 lib/silccrypt/silcpkcs.[ch].
1268 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * The client entry's userinfo pointer must be always valid.
1271 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1272 will fail since it requires the userinfo. Now, the userinfo
1273 is allocated as "" if actual userinfo does not exist. Actually,
1274 it must exist and it is totally Ok to drop client connections
1275 that does not announce the userinfo. However, we will make
1276 this workaround for now.
1278 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1279 to return the remote port by socket.
1281 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1284 SILC_SERVER_PENDING_EXEC and added an new macro
1285 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1286 data or when error occurs while processing the pending command.
1288 Added new argument `destructor' into silc_server_command_pending
1289 and to the SilcServerCommandPending object. This destructor is
1290 now called after calling the pending callback or if error occurs
1291 immediately. If error occurs the actual pending callback won't
1292 be called at all - only the destructor. The destructor may be
1293 NULL if destructor is not needed.
1295 All this applies for client library code as well. Similar
1296 changes were made there as well for the pending commands.
1298 In the client, the application must now allocate the
1299 SilcClientCommandContext with the silc_client_command_alloc
1302 * Added reference counter to the SilcServerCommandContext. Added
1303 function silc_server_command_alloc and silc_server_command_dup
1306 Same type of functions added to the client library for the same
1309 * Removed the cmd_ident from IDListData away since it is now
1310 global for all connections. It is the command identifier used
1311 in command sending and with pending commands. The affected file
1314 * Added reference counter to the SilcSocketConnection objecet to
1315 indicate the usage count of the object. The object won't be
1316 freed untill the reference counter hits zero. Currently only
1317 server uses this, and client ignores it. The client must be
1318 set to use this too later. The affected files are
1319 lib/silccore/silcsockconn.[ch]. Added also the function
1320 silc_socket_dup to increase the reference counter.
1322 This was mainly added because it is possible that the socket
1323 is removed underneath of pending command or other async
1324 operation. Now it won't be free'd and proper DISCONNECTING
1325 flags, etc. can be set to avoid sending data to connection that
1326 is not valid anymore.
1328 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1329 the connection. After that it sets SILC_SET_DISCONNECTED.
1330 It is, however, possible that the socket data is not still freed.
1331 The silc_server_packet_process now checks that data is not
1332 read or written to connection that is DISCONNECTED. The socket
1333 get's freed when the reference counter hits zero.
1335 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Changed the client operation API: channel_message operation's
1338 `sender' is now the client entry of the sender, not the nickname
1339 and the `channel' is the channel entry, not the channel name.
1341 In the private_message operation the `sender' is now also the
1342 client entry of the sender not the nickname.
1344 Affected file is lib/silcclient/ops.h and all applications
1345 using the client operations.
1347 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Moved the calling of ops->connect() from connect_to_server_final
1350 into receive_new_id functin since that is the point when the
1351 client is actually allowed to send traffic to network. The
1352 affected file is lib/silcclient/client.c.
1354 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1357 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1358 (if needs broadcasting) instead of broadcasting the packets one
1359 by one which would make a burst in the network traffic.
1361 * Added `broadcast' argument to the functions in silcd/server.[ch]
1362 silc_server_create_new_channel[_with_id] to indicate whether
1363 to send New Channel packet to primary router.
1365 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Added new function into the silcd/server.[ch] files:
1368 silc_server_create_new_channel_with_id to create new channel with
1369 already existing Channel ID.
1371 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1372 lib/silccore/silcpacket.h. This packet is used t send list of
1373 Set Mode payloads inside one packet. Server uses this to set
1374 the modes for the channels and clients on those channels, that it
1375 announced to the router when it connected to it. The protocol
1376 specification has been updated accordingly.
1378 * The silc_server_new_channel did not handle the packet coming
1379 from normal server as it normally does not send that. However,
1380 when it announces its channels it does send it. Implemented
1381 the support for that.
1383 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1384 into the file lib/silccore/id.h.
1386 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Fixed memory leaks in the functions silc_idlist_del_client,
1389 silc_idlist_del_channel and silc_idlist_del_server in the file
1390 silcd/idlist.c. All of those leaked like a sieve.
1392 * Fixed some small memory leaks in the client's function
1393 silc_client_notify_by_server.
1395 * Added functions into silcd/server.c: silc_server_announce_clients,
1396 silc_server_announce_channels and silc_server_announce_server.
1397 These functions are used by normal and router server to announce
1398 to its primary router about clients, channels and servers (when
1399 router) that we own. This is done after we've connected to the
1402 These functions effectively implements the following packet types:
1403 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1404 and SILC_PACKET_NEW_ID_LIST.
1406 * Added new functions into the silcd/packet_receive.[ch]:
1407 silc_server_new_id_list, silc_server_new_channel_list and
1408 silc_server_new_channel_user_list to handle the incoming
1409 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1411 * Added support of changing Channel ID in the function
1412 silc_server_replace_id. If the server that announces a channel
1413 to the router already exists in the router (with same name but
1414 with different Channel ID), router is responsible to send
1415 Replace ID packet to the server and force the server to change
1416 the Channel ID to the one router has.
1418 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1419 client that the Channel ID has been changed by the router. The
1420 normal server sends this to the client. Client must start using
1421 the new Channel ID as the channel's ID.
1423 Implemented handling of this new type into lib/silcclient/client.c
1424 into the function silc_client_notify_by_server.
1426 * Added new function silc_idlist_replace_channel_id into the files
1427 silcd/idlist.[ch] to replace the Channel ID.
1429 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Call silc_server_command_identify_check always when processing
1432 the IDENTIFY command in silcd/command.c
1434 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1437 send keepalive packets. The packet can be sent by clients,
1438 servers and routers.
1440 Added function silc_socket_set_heartbeat into the file
1441 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1442 If not set, the heartbeat is not performed. The actual
1443 heartbeat is implemented in the low level socket connection
1444 library. However, application is responsible of actually
1447 Added silc_server_send_heartbeat to send the actual heartbeat
1448 packet into silcd/packet_send.[ch]. Server now performs
1449 keepalive with all connections.
1451 * Added silc_task_get_first function into lib/silcutil/silctask.c
1452 to return the timeout task with shortest timeout. There was a bug
1453 in task unregistration that caused problems. TODO has been
1454 updated to include that task system must be rewritten.
1456 * The client library will now resolve the client information when
1457 receiving JOIN notify from server for client that we know but
1458 have incomplete information.
1460 * Rewrote parts of silc_server_remove_from_channels and
1461 silc_server_remove_from_one_channel as they did not remove the
1462 channel in some circumstances even though they should've.
1464 * Encryption problem encountered in server:
1466 The LEAVE command used to send the Channel Key packet to the
1467 router immediately after generating it. However, the code
1468 had earlier sent Remove Channel user packet but not immediately,
1469 ie. it was put to queue. The order of packets in the router
1470 was that Channel Key packet was first and Remove Channel User
1471 packet was second, even though they were encrypted in the
1472 reverse order. For this reason, MAC check failed. Now, this
1473 is fixed by not sending the Channel Key packet immediately but
1474 putting it to queue. However, this is more fundamental problem:
1475 packets that are in queue should actually not be encrypted
1476 because packets that are sent immediately gets encrypted
1477 actually with wrong IV (and thus MAC check fails). So, packets
1478 that are in queue should be encrypted when they are sent to
1479 the wire and not when they put to the queue.
1481 However, the problem is that the current system has not been
1482 designed to work that way. Instead, the packet is encrypted
1483 as soon as possible and left to the queue. The queue is then
1484 just purged into wire. There won't be any fixes for this
1485 any time soon. So, the current semantic for packet sending
1488 o If you send packet to remote host and do not force the send
1489 (the packet will be in queue) then all subsequent packets to the
1490 same remote host must also be put to the queue. Only after the
1491 queue has been purged is it safe again to force the packet
1494 o If you send all packets immediately then it safe to send
1495 any of subsequent packets through the queue, however, after
1496 the first packet is put to queue then any subsequent packets
1497 must also be put to the queue.
1499 Follow these rules and everything works fine.
1501 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Added new function silc_server_remove_clients_by_server to
1504 remove all client entries from ID list when the server connection
1505 is lost. In this case it is also important to invalidate all
1506 client entires as they hold the invalid server entry. This
1507 fixes fatal bug when server has lost connection and will reconnect
1510 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * Made some sanity checks to silc_server_daemonise like to check
1513 whether the requested user and group actually exists.
1515 * Added sanity check to SKE's silc_ske_responder_finish to check
1516 that the public and private key actually is valid.
1518 * Invalidate the client's nickname when receiving Replace ID
1519 packet and the Client ID is being replaced. This means that the
1520 server will query the nickname if someone needs it (client)
1523 * Sort the ID Cache in client library when the ID Cache data
1524 has changed (needs sorting).
1526 * Do not allow for SILC client to create several connections to
1527 several servers. The client does not support windows right now
1528 and generating multiple connections causes weird behaviour.
1530 Irssi-silc client does support windows and can handle several
1531 connections without problems, see: www.irssi.org and SILC plugin.
1533 * Fixed some places where client was added to the IDList. The
1534 rule of thumb is following (in order to get everything right):
1535 If the client is directly connected local client then the
1536 `connection' argument must be set and `router' argument must be
1537 NULL to silc_idlist_add_client function. If the client is not
1538 directly connected client then the `router' argument must
1539 bet set and the `connection' argument must be NULL to the
1540 silc_idlist_add_client function.
1542 * The funtion silc_server_packet_send_local_channel actually did
1543 not check whether the client was locally connected or not. It
1544 does that now. Fixed a bug related to LEAVE command.
1546 * Fixed Remove Channel User payload parsing bug in server's
1547 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1549 * The server's silc_server_save_channel_key now checks also the
1550 global ID list for the channel as it might not be in the local
1551 list. Fixed a bug related to LEAVE command.
1553 * Is this the end of the [<unknown>] buglet that has been lurking
1554 around for a long time? A little for loop fix in server's
1555 silc_server_command_whois_parse that is used by both IDENTIFY
1556 and WHOIS command. At least, this was a clear bug and a cause
1557 of one type of [<unknown>] buglet.
1559 * WHOIS and IDENTIFY commands call the function
1560 silc_server_command_[whois/identify]_check function even if
1561 we are not router server.
1563 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Added --with-gmp configuration option. If set the GMP
1566 is always compiled in the SILC source tree. If not set then
1567 it is checked whether the system has the GMP3 installed. If
1568 it has then the GMP won't be compiled (the system's headers
1569 and library is used), if it doesn't have it then the GMP is
1570 compiled in the SILC source tree.
1572 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Changed RSA private exponent generation to what PKCS #1
1575 suggests. We try to find the smallest possible d by doing
1576 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1577 not security fix but optimization.
1579 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Added new config entry [Identity] to fork the server and run
1582 it as specific user and group. A patch from Bostik.
1584 * Imported Dotconf configuration library into lib/dotconf.
1585 This will be used to create the SILC configuration files later.
1586 It will appear in the distsribution after this commit.
1588 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * A big code auditing weekend happening. Auditing code for
1591 obvious mistakes, bugs and errors. Also, removing any code
1594 Removed files for being obsolete:
1596 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1597 inline in the file lib/silcutil/silcbuffer.h)
1599 o lib/silcutil/silcbufutil.c (the header has inline versions)
1601 Changed code to fix possible error conditions:
1603 o The buffer formatting routines now check that the destination
1604 buffer really has enough space to add the data. This applies for
1605 both buffer formatting and unformatting
1606 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1607 unformatting was changed to accomodate following rules:
1608 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1609 sent to the function while XXX_*STRING will not allocate or copy
1610 the data into the buffer. Instead it sets the pointer from the
1611 buffer into the pointer sent as argument (XXX_*STRING used to
1612 require that the pointer must be allocated already). This change
1613 makes this whole thing a bit more consistent and more optimized
1614 (note that the data returned in the unformatting with XXX_*STRING
1615 must not be freed now). The routines return now -1 on error.
1617 o Tried to find all code that use buffer_format and buffer_unformat
1618 and added return value checking to prevent formatting and
1619 especially unformatting errors and possible subsequent fatal
1622 o Changed ske->x and ske->KEY to mallocated pointers in
1623 lib/silcske/silcske.h. Fixed possible data and memory leak.
1625 o Added return value checking to all *_parse* functions. Fixed
1626 many memory leaks as well.
1628 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1629 so that buffer overflows would not happen. All code now also
1630 checks the return value as it can fail.
1632 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Added reconnection support to server if the normal server looses
1635 its connection to the router (for example if router is rebooted).
1636 The server performs normal reconnection strategy implemented
1637 to the server. Affected file silcd/server.c.
1639 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Added new packet type SILC_PACKET_SET_MODE that is used to
1642 distribute the information about changed modes (for clients,
1643 channels and clients channel modes) to all routers in the
1644 network. Updated the protocol specification accordingly.
1646 Added functions into silcd/packet_send.c and
1647 silcd/packet_receive.c: silc_server_send_set_mode,
1648 silc_server_set_mode.
1650 Added new files silcmode.[ch] into lib/silccore that implements
1651 the encoding and decoding of Set Mode Payload. Added new type
1652 SilcSetModePayload. Moved the definitions of different modes
1653 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1655 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Oops, a little mistake in server's connection authentication
1658 protocol. The protocol is not ended with FAILURE but with
1659 SUCCESS if the authentication is Ok. :) Affected file is
1662 * Implemented NICK_CHANGE notify handling in server in the file
1663 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1664 the local clients on the channel. After the changing nickname
1665 in router environment snhould work and the [<unknown>] nickname
1666 should appear no more.
1668 The silc_server_replace_id function that receives the Replace ID
1669 payload now sends the NICK_CHANGE notify type also in the file
1670 silcd/packet_receive.c
1672 * Changed WHOIS and IDENTIFY command to support the maximum amount
1673 of arguments defined in protocol specs (3328 arguments). This
1674 fixed a bug that caused problems when there were more than three
1677 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1679 * Added extra parameter, command identifier, to the
1680 silc_client_send_command so that explicit command identifier
1683 Changed that ID list routines uses specific command identifier
1684 when sending WHOIS/IDENTIFY requests to the server so that they
1685 can be identified when the reply comes back.
1687 Affected files lib/silcclient/command.[ch],
1688 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1690 * Added `sender' argument to silc_server_packet_send_to_channel
1691 to indicaet the sender who originally sent the packet to us
1692 that we are now re-sending. Ignored if NULL. Affected file
1693 silcd/packet_send.[ch].
1695 * Added some server statistics support in silcd/server_internal.h
1696 SilcServerStatistics structure and around the server code. Also
1697 send some nice statistics information when client is connecting
1700 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Fixed channel ID decoding in server's JOIN command reply in
1703 silcd/command_reply.c
1705 * Fixed braodcasting of replace ID payload to not to send it if
1706 we are standalone server in silcd/packet_receive.c.
1708 * Fixed all channel message sending routines to not to send
1709 packets to clients that has router set, since they are routed
1710 separately in the same function earlier. Affects file
1711 silcd/packet_send.c and all channel packet sending functions.
1713 * In USERS reply, res_argv[i] are not allocated, the table
1714 is allocated. Thus changed that free the table, not its
1717 * In server's whois_check and identify_check if the client is
1718 locally connected do not send any WHOIS commands - they are not
1721 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Fixed some minor bugs in client when sending WHOIS command. The
1724 arguments was in wrong order.
1726 * Removed statis function add_to_channel from server in
1727 silcd/command.c that was previously used with the joining but
1730 * Tested USERS command in router environment successfully with two
1731 routers, two servers and two clients.
1733 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Reorganized the USERS command and command reply in client library
1736 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1737 When the command is given by user we register a pending command
1738 callback that will reprocess the command after the reply has been
1739 received from the server. When reprocessing the packet we then
1740 display the information. Thus, the USERS information is displayed
1741 now in the command callback instead of in the command reply
1742 callback. The processing of the command is same as previously
1743 when server has sent the command reply in the JOINing process.
1745 * Added to USERS command in silcd/command_reply.c to join the client,
1746 we didn't use to know about, to the channel after we've created
1747 a client entry for it. Also, for clienet we did know already still
1748 check whether it is on the channel or not and add it if not.
1750 * Removed silc_server_command_join_notify as the function and its
1753 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Changed the client's pending command handling to the same as the
1756 server's pending command handling. It is also now possible to
1757 execute command reply functions from other command reply
1758 function as the function callbacks for commands and command
1759 replies are one and same. The pending commands are not static
1760 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1761 in client connection context. Thus, pending commands are server
1762 connection specific as it is convenient.
1764 Changed the function silc_client_command_pending and
1765 silc_client_command_pending_del and added new function
1766 silc_client_command_pending_check. Removed the
1767 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1770 * Added cmd_ident, current command identifier, to the client
1771 connection context in lib/silcclient/client.h to keep track on
1772 command identifiers used in command sending. Client's command reply
1773 function handling now supports the mandatory command identifiers.
1775 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1776 funtions in client to fully support pending command callbacks.
1778 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1779 as one of the arguments to the application in the command reply
1782 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1783 before first releasing SILC but came back. Now it is removed again
1784 and should come back nomore. The FORWARDED flag was used only
1785 by the JOINing procedure by forwarding the command packet to router.
1786 Now, the JOINing procedure has been changed to more generic (due
1787 to various router environment issues) and FORWARDED is not needed
1788 anymore for anything. The protocol specification is yet to be
1791 Now, removed silc_server_packet_forward from server and the flag
1792 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1794 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1796 * Renamed NAMES command to USERS command. The NAMES was named that
1797 due to historical reasons. Now it is renamed. Also, rewrote
1798 parts of the USERS command. The nickname list is not sent anymore
1799 by the server. Only Client ID and mode lists are sent in the USERS
1800 command. Changed this also to the protocol specification.
1802 The client now resolves the names and stuff after it receives
1803 the USERS list from the server when joining to the channel.
1805 * WHOIS and IDENTIFY commands has been changed to support multiple
1806 Client ID's per command. One can now search for multiple users
1807 in the network by sending only one WHOIS or IDENTIFY command.
1808 Changed the code and the protocol specifications.
1810 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1811 uses silc_server_command_whois_parse to parse the request. */
1813 * If normal server, do not parse the WHOIS and IDENTIFY requests
1814 before sending it to the router. Saves some time.
1816 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Fixed JOIN command on client library. Wrong number of arguments
1819 used to crash the client.
1821 * Added silc_server_channel_has_global function to check whether
1822 channel has global users or not.
1824 * Added silc_server_channel_has_local function to check whether channel
1825 has locally connected clients on the channel.
1827 * The silc_server_remove_from_one_channel now checks whether the
1828 channel has global users or not after given client was removed from
1829 the channel. It also checks whether the channel has local clients
1830 on the channel anymore. If it does not have then the channel entry
1831 is removed as it is not needed anymore.
1833 * The silc_server_notify now checks on JOIN notify whether the joining
1834 client is one of locally connected or global. If it is global then
1835 the channel has now global users on the channel and that is marked
1836 to the channel entry. Also, it now saves the global client to
1837 global list who is joining and JOINs it to the channel. This is
1838 for normal server, that is.
1840 Changed silc_server_send_notify_on_channel,
1841 silc_server_packet_relay_to_channel and
1842 silc_server_packet_send_to_channel check if we are normal server
1843 and client has router set (ie. global client) do not send the
1844 message to that client, as it is already routed to our router.
1846 * Implemented LEAVE notify type handling in silc_server_notify
1849 * Tested LEAVE command in router environment successfully. Tested
1850 with two routers, two servers and two clients.
1854 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1856 * Implemented SIGNOFF notify type handling in silc_server_notify
1859 * silc_server_remove_id now removes the client entry from all channels
1860 it has joined and thusly sends SIGNOFF notify type.
1862 * Rewrote the NAMES list generation in server by removing two excess
1863 loops. The lists are created now inside one loop.
1865 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * silc_server_remove_channel_user checks now also global list
1868 for channel and client.
1870 * silc_server_new_channel_user checks now both local and global
1871 list for channel and client. Fixed a bug in client id decoding.
1872 Used to decode wrong buffer.
1874 * silc_server_channel_message checks now both local and global
1875 list for channel entry.
1877 * Tested channel joining (hence JOIN) in router environment
1878 successfully. Tested with two routers, two servers and two
1881 * Tested channel message sending in router environment successfully.
1883 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Added silc_server_save_channel_key into server.[ch] to save the
1886 received channel key in Channel Key payload processing. It is
1887 also used in JOIN command reply handling.
1889 Equivalent function silc_client_save_channel_key added into
1890 client.[ch] into client library.
1892 * Changed JOIN command reply to send information whether the channel
1893 was created or not (is existing already) and the channel key
1894 payload. Changed protocol specs accordingly.
1896 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1897 the request was sent by ID and not by nickname. Crashed on
1900 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1903 now correctly save the received data.
1905 * silc_server_free_sock_user_data now notifies routers in the
1906 network about entities leaving the network.
1908 At the same time implemented functions silc_server_remove_id
1909 and silc_server_send_remove_id to receive and send REMOVE_ID
1910 packets. The packet is used to notify routers in the network
1911 about leaving entities. The ID removed will become invalid in
1914 * Added function silc_idlist_del_server into server. Removes and
1915 free's server entry from ID list.
1917 * silc_server_private_message function now checks, if we are router,
1918 that the destination ID really is valid ID, naturally.
1920 * In router when NEW_ID packet is received (for new client) the
1921 hash of the Client ID is saved in the ID Cache but the
1922 client->nickname is set to NULL, instead of putting the hash
1925 IDENTIFY command now also checks that client->nickname must be
1926 valid. If it is not if will request the data from the server who
1927 owns the client. Added new function
1928 silc_server_command_identify_check.
1930 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1931 to set the command to already allocated Command Payload.
1933 * Tested private message sending in router environment with two
1934 routers, two servers and two clients. Fixed minor bugs and now
1937 * Fixed segfault from client's NAMES command. Used to crash if
1940 * Forwarded packets must not be routed even if it is not destined
1941 to the receiver. Changed server code comply with this.
1943 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added `require_reverse_mapping' boolean value to ServerParams
1946 structure. If TRUE (not default) the server will require that
1947 the connecting host has fully qualified domain name.
1949 If the reverse mapping is not required and hostname could not be
1950 found the IP address is used as hostname.
1952 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Implemented version string checking to both client and server.
1955 The check is incomplete currently due to the abnormal version
1956 strings used in development version of SILC.
1958 * Changed all command functions in server to use the new
1961 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Changed char *data to unsigned char *data in ID Cache system to
1964 support binary data as ID Cache data. Changed code to support
1965 binary data in lib/silccore/idcache.c.
1967 * Renamed silc_server_packet_relay_command_reply to
1968 silc_server_command_reply as it is normal packet receiving
1969 function. Rewrote the function to accept command replys for
1970 servers and not only for clients.
1972 * Mark remote router always as registered server if we are connecting
1973 to it. Otherwise, commands sent by the router to us are ignored.
1975 * All ID List find routines now returns the ID Cache Entry pointer
1976 as well if requested.
1978 * WHOIS command works now in router environment, tested with two
1979 routers, two servers and two clients.
1981 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1982 in router environment (as it is almost equivalent to WHOIS) but
1983 hasn't been tested thoroughly. Added new functions:
1985 silc_server_command_identify_parse
1986 silc_server_command_identify_send_reply
1987 silc_server_command_identify_from_client
1988 silc_server_command_identify_from_server
1990 * Disabled route cache adding because adding two different ID's with
1991 same IP replaces the old cache entry thus giving wrong route.
1992 The entry->router->connection is always the fastest route anyway
1993 so route cache may not be needed. Of course, new routes maybe
1994 established after receiving the ID when the entry->router->connection
1995 might not be anymore the most optimal.
1997 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Add route cache for received ID for fast routing.
2001 * Added silc_server_packet_route to route received packet on router
2002 that is not destined to us.
2004 * Renamed silc_server_get_route to silc_server_route_get.
2006 * Added id_string and id_string_len fields into SilcServer to
2007 include encoded ServerID for fast comparing without excess
2008 encoding of the ID's.
2010 * Cleaned up WHOIS command on server side. Added following static
2013 silc_server_command_whois_parse
2014 silc_server_command_whois_check
2015 silc_server_command_whois_send_reply
2016 silc_server_command_whois_from_client
2017 silc_server_command_whois_from_server
2019 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2020 arguments in command replies. All command functions should be
2021 updated to use this macro.
2023 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Minor typo fixes on command reply handling on server.
2027 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Added silc_server_command_add_to_channel internal routine to add
2030 the client to the channel after router has created the channel and
2031 sent command reply to the server.
2033 * Added generic silc_server_send_command to send any command from
2036 * Use static buffer with ID rendering instead of duplicating data.
2038 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Fixed a channel user mode bug when joining to a channel server gave
2041 everybody channel founder rights, oops.
2043 * We mark ourselves as the router of the incoming server connection
2044 if we are router ourselves. This way we can check in some packet
2045 sending functions whether it is locally connected server. For
2046 incoming router connections we put NULL.
2048 * For router sending packets locally means now always sending the
2049 packet cell wide; to local clients and local servers. For normal
2050 server sending packet locally means sending it to only local
2053 * Fixed the JOIN command to really work in router environment. If the
2054 channel is created it is always created by the router. Router is
2055 also responsible of making the initial joining to the channel,
2056 sending JOIN notify to the sending server and distributing
2057 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2058 does not exist server doesn't do anything else but forward the
2059 command to the router which performs everything.
2061 * Added silc_server_send_channel_key function to send the Channel Key
2064 * Added silc_server_create_channel_key to create new channel key. The
2065 channel key is now re-generated everytime someone joins or leaves
2066 a channel, as protocol dictates. Note: channel->key_len is the
2069 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2072 packet_receive.[ch] to separate packet sending and receiving
2073 routines. The server.[ch] now includes everything else including
2074 actual packet processing (writing and reading data) and other
2077 Renamed silc_server_private_message_send_internal to
2078 silc_server_send_private_message. The routine is still though
2079 used only to relay private messages as server does not send
2080 private messages itself.
2082 Renamed silc_server_new_channel to silc_server_create_new_channel
2083 and added new function sicl_server_new_channel that handles the
2084 incoming New Channel packet. Added also new sending function
2085 silc_server_send_new_channel to send New Channel Payload.
2087 * Added new function silc_server_notify to process incoming notify
2088 packet to the server/router. Server may then relay the notify
2089 to clients if needed.
2091 * Added new function silc_server_new_channel_user to process incoming
2092 New Channel User packet. Router will redistribute the packet and
2093 send JOIN notify to its local clients and locally connected servers
2094 if needed. Normal server will send JOIN notify to its local client
2095 on same channel when received this packet. Added also corresponding
2096 sending function silc_server_send_new_channel_user to sent the
2099 * Added boolean route argument to send_notif_to_channel and
2100 packet_send_to_channel functions to attempt to route the packet
2101 if it is TRUE and send only locally if it is FALSE.
2103 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * silc_server_replace_id now broadcasts the received replace ID
2106 packet if it is not broadcast packet already. The router must
2107 broadcast to inform other routers about changed ID.
2109 * Added backpointer to server's router into SilcServer context in
2110 silcd/server_internal.h.
2112 * Fixed silc_server_packet_broadcast to send correct broadcast
2115 * The channel key is now distributed to the local client as soon
2116 as it is received from the router (in router environment) so that
2117 no other packet may be sent for the channel until client has
2120 * silc_server_remove_channel_user now broadcasts the received
2121 Remove Channel User packet if it is not broadcast packet already.
2122 The router must broadcast to inform other routers about removed
2125 * Added users field into SilcPacketContext that is a reference count
2126 of the context. One can increase the reference count by calling
2127 silc_packet_context_dup which is now changed to just increase the
2128 reference count instead of duplicating the data. The reference
2129 count is decresed by calling silc_packet_context_free that will
2130 free the data after the reference count hits zero.
2132 For now on the packet context and everything allocated into it
2133 (including the raw packet from network) must be freed by calling
2134 the new silc_packet_context_free function. Added also new function
2135 silc_packet_context_alloc that must be used now to allocate the
2136 context. This also means that if a routine is asynchronous from
2137 silc_[client/server]_packet_parse_type the packet context must
2138 be duplicated by calling silc_packet_context_dup. Otherwise it
2139 gets free'd after silc_[client/server]_packet_parse_type returns.
2140 Also, one must remember that if packet is duplicated then its
2141 reference count must be decresed by calling the free function as
2142 many times as it was duplicated.
2144 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2145 from both client and server.
2147 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Made joining to a channel working in router environment.
2151 * Cleaned up JOIN command on server side and create function
2152 silc_server_command_join_channel internal routine to make the
2155 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Changed silc_command_pending list to SilcDList. Also, added
2158 `ident' field to SilcServerCommandPending structure to identify
2159 the reply and to call correct callback.
2161 Added silc_server_command_pending_check function to replace the
2162 corresnponding macro. The silc_command_pending list is not
2165 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2166 to set identifier to previously allocated Command Payload. It
2167 is used to set identifier for command when resending Command
2170 * Added silc_command_payload_encode_payload to encode Command
2171 Payload buffer from SilcCommandPayload structure.
2173 * Added silc_argument_payload_encode_payload to encode Argument
2174 payload buffer from SilcArgumentPayload structure.
2176 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Changed WHOIS command to support router connection on server side.
2179 The whois request is always sent to router unless the server is
2180 standalone server. After server has received the reply from the
2181 router will it send the reply to the client.
2183 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2184 broadcast received broadcast packet. The function is used only
2185 by router. The broadcast packet is always sent to the router's
2188 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2189 render given ID to printable string, for log files for example.
2191 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Made basic router to router connections working. At least they
2194 can now connect to each other but nothing really works the way
2195 they are supposed - yet.
2197 * Added new initiator token to RouterConnection configuration
2198 file in silcd/serverconfig.[ch]. It is used to tell whether we
2199 are the initiator to the remote router or whether we'll expect
2200 the other end to connect.
2202 * Moved registering of listener task to silc_server_init, hence
2203 the server starts listenning as soon as it is run, even if it
2204 does not have connections to other routers. Let's see how well
2207 * Changed default connection retry timeouts for more suitable in
2210 * Removed cipher and such arguments from silc_idlist_add_client
2211 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2212 Added new function silc_idlist_add_data to add the keys and stuff
2215 * Added SilcIDListData structure and added it to SilcClientEntry
2216 and SilcServerEntry as their first field in the structure. This
2217 way we can explicitly cast the ID entries to the SilcIDListData
2218 structure and get common data for the entries. In past, we had
2219 to first check what type of connection it is and then cast it to
2220 correct ID entry type. Now, we can directly cast the opaque
2221 pointer to the SilcIDListData (no matter what ID entry it actually
2222 is) and get the data needed.
2224 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2227 in some circumstances even if threre were timeout tasks, though not
2228 IO tasks, but tasks anyway. Now fixed.
2230 * Defined SilcServerConnection structure to hold connection specific
2231 stuff about directly connected servers and routers. The definition
2232 is currently in silcd/server_internal.h. I thought about having
2233 a bit more important role fro this struct but for now it is used
2234 only when connecting to other server (or router actually).
2236 * Added connecting retry support in server when connecting to
2237 router(s). The retry feature implement exponential backoff
2238 algorithm. Also, added SilcServerParams structure to hold default
2239 parameters for server. For now, it include these retry settings
2240 and are hard coded. After server is moded to be as Silc Server
2241 Library this structure will be more important.
2243 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Changed client librarys channel->clients table to SilcList and
2246 changed code accordingly.
2248 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Changed client's channel table to SilcList and changed code
2251 accordingly. Also changed SilcChannelClientEntry to include back-
2252 pointer to the channel so that client entry can use that structure
2253 as list as well and we have fast cross-reference to the channel.
2254 This change dramatically decreased the complexity of channel
2255 handling with client entry and vice versa (removed one extra
2256 loop when searching for channel entry from many functions).
2258 * Changed server->sim from table to SilcDList and changed code
2261 * NAMES command can now be used from user interface. It will show
2262 the user list on the channel, neatly.
2264 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2265 Code now saves realname of the user if it becomes available.
2267 * Renamed configure.in to configure.in.pre and made ./prepare
2268 script to automatically add correct version string to
2269 configure.in which it creates from configure.in.pre.
2271 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * NAMES command reply now shows users mode with the nickname when
2276 * Moved silc_client_ch[u]mode[_char] functions from
2277 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2278 place sucks, they are utility functions and should be in some
2281 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2283 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2286 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Added TRQ (efficient deque and list library) into lib/trq. This is
2291 a very good list library that is currently used in the SILC. Defined
2292 SilcList API over the library because I didn't like the API very
2293 much. See lib/trq/silclist.h for the API and examples of how to
2294 use the API. Fixed various places in the code to use the new
2295 SilcList API. The SilcList is meant for lists that has a structure
2296 already defined as a list. It is not suitable to add just some
2297 context to the list (in TRQ, the context is the list actually).
2299 So, I defined SilcDList that can be used for the purpose where
2300 predefined list structure does not exit. This can be used as
2301 such list. Now some context just can be added to the SilcDList.
2302 Currently this list is not used in the SILC just yet, though there
2303 are a lot places where this can replace dynamically allocated
2304 tables and I will fix these places, later, to use SilcDList.
2305 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2306 and use TRQ internally).
2308 Also fixed some annoying warning messages that the original TRQ
2309 code generated. Also minor changes to TRQ's Makefile.in.
2311 * Added support for querying by Client ID to both WHOIS and
2312 IDENTIFY commands into server, as required by the protocol.
2314 * Removed method function pointers from SilcBuffer structure. They
2315 weren't used to anything and just increased the context size for
2316 no good reason. This change also made silc_buffer_alloc and
2317 silc_buffer_free functions inline functions.
2319 * Disabled command flooding detection support until it's fixed so
2320 that it accepts commands in but does not execute them more than once
2323 * Added silc_net_localhost(), to return local hostname, into
2324 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2325 that must be initialized before calling silc_client_init.
2327 * Added new function: silc_server_send_notify_on_channels to send
2328 notify messages to all channels client has joined. It is assured
2329 that the message is sent only once per client.
2331 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2332 lib/silcutil/silcutil.[ch] as silc_format function. The new
2333 function is generic and is used by server as well, not only by
2334 the logging routines.
2336 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2337 the provided version string was not acceptable. Added new function:
2338 silc_ske_check_version into lib/silcske/silcske.h. The function
2339 must be implemented by the application (client or server) and it
2340 does not reside in the SKE library. The function checks the version
2341 string remote end sent.
2343 * Added back pointers (to opaque context and to SilcSocketConnection)
2344 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2346 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2347 duplicate packet context structure.
2349 * Changed `notify' client operation to send same arguments as client
2350 receives from server except for ID's. ID's are mapped to correct
2351 ID entry and that is returned. Also, if channel entry is not sent
2352 by server but the notify is for channel the channel entry is sent
2353 to application (otherwise application doesn't know that it is for
2354 channel (library gets it from packet's Destination ID)).
2356 * Added silc_client_remove_from_channels into client library to
2357 remove a client from all channels it has joined to. Used when
2358 received SIGNOFF notify from server. Added also new function
2359 silc_client_replace_from_channels to replace old ID entry with
2360 new ID entry on all channels. Used when received NICK_CHANGE
2363 * Fixed ID Cache list handling in silc_idlist_get_client in
2364 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2365 to get (or query) client by ID.
2367 * Updated TODO list.
2369 * Added connection authentication status message defined by the
2370 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2371 support for these into the code in client and server side.
2373 * Added generic function silc_client_send_command to send any command
2374 with variable argument list. Application should use this function
2375 to send commands if the command functions provided by the library
2376 does not suite for the application's user interface needs.
2378 * Added new `failure' client operation. Application is notified about
2379 received failure packet if client is executing a protocol. In this
2380 case the protocol's execution has failed.
2382 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2383 is required by the protocol.
2385 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2386 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2389 * Added status flag to SilcSKE object to indicate realtime status
2390 of the SKE protocol.
2392 * Application receives now exactly same command reply arguments as
2393 the library receives from server. However, if ID is received the
2394 corresponding ID entry is returned to the application (eg. Client
2395 ID is mapped to correct SilcClientEntry entry and that is returned).
2396 Changed command_reply client operation due to this change.
2398 * Changed all ID's in commands and in command replys as ID Payloads.
2399 Change affected both client and server side codes.
2401 All ID's sent in SILC network (with execption of ID's in SILC
2402 Packet header) are sent in ID Payload to support variable length
2405 * Server now notifies nick changes and notifies all clients on
2406 the channels about the new nickname (about the new Client ID,
2409 * Implemented CMODE command to change channel modes. Supports all
2410 channel modes defined by the protocol specs except ban and invite
2411 lists. (Also, private channel key mode is supported but support for
2412 setting private channel key in client is missing, thus, this mode
2413 has no effect on client side (except that server requires that the
2414 client uses private channel key and normal channel traffic does not
2417 Also, invite mode works per se, but INVITE command does not work
2418 yet correctly, so you can set channel as invite only channel but
2419 inviting clients to the channel does not work (it is yet to be
2420 thought what's the best way to do it).
2422 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2423 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2424 Implemented CUMODE command to change user's mode on the channel.
2425 Supports all modes defined by the protocol specs.
2427 * Added NAMES command reply to return users modes on the channel.
2429 * Removed unnecessary and slow ciphers from lib/silccrypt.
2431 * Set SO_KEEPALIVE option to connection sockets by default.
2433 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2435 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2436 redefined the Notify Payload into protocol specs.
2438 * Added silc_id_payload_parse_id to get ID directly from raw
2441 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2444 accept searching by Client ID as well.
2446 * Added support for LEAVE and SIGNOFF notify types in client library.
2448 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2449 to parse ID Payload from raw data.
2451 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Added flags parameter into silc_ske_assemble_security_properties
2454 function in lib/silcske/silcske.[ch].
2456 * Changed notify client operation to fit better for notify messages
2457 sent by server. The notify payload received from server is now
2458 passed to the application (after parsing it to SilcNotifyPayload).
2459 It is application's responsibility to retrieve the arguments
2460 from the payload and show the message the way it wants. The message
2461 sent by server is implementation specific.
2463 * Changed public keys to comply with the protocol specification.
2464 Old public keys are not supported anymore and are not compatible.
2466 * Removed nickname from Channel Payload as the latest draft removed
2467 it. The client must resolve the nickname from the NAMES command
2468 reply received when it joined the channel.
2470 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2472 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Fixed some errors in protocol specification drafts.
2476 * Created lib/silccore/silcnotify.c to implement Notify Payload
2477 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2478 generic payloads described by protocol specifications. The file
2479 includes implementations for ID Payload and Argument Payload.
2481 * Changed Command Payload implementation to use the new Argument
2482 Payload. Changed command_xxxx_payload to command_payload_xxxx
2483 to comply with SILC coding conventions.
2485 * Added suppport for Argument Payload handling in Notify Payload
2486 implementation as protocol requires it. Added the new support
2487 into server and client lib as well.
2489 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added support for multiple nicknames on same channel. [n] is
2492 added locally to the nickname if there are more than one same
2493 nicknames on the channel.
2495 * Server now sends all nicknames that matched WHOIS request.
2496 Client also shows the list received from server.
2498 * Added TOPIC command to client side. User can now set and show
2499 current topic on channel.
2501 * Added MOTD command to client and server. Also, server sends the
2502 motd when client connects to the server.
2504 * Changed version strings to comply ISO 8601.
2506 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Fixed protocol error handling in client library. It should now
2509 cope even if the SKE fails for some reason.
2511 * Made new protocol specification drafts for submitting to IETF.
2513 * Implemented TOPIC command to server in silcd/command.c.
2515 * Added two new notify types into lib/silccore/silcnotify.h:
2516 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2517 notify nickname change and topic setting/change on a channel.
2519 * API change of command_reply operation in client library. The
2520 application gets now the status type received from server as well.
2522 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2526 * Cras fixed and optimized the packet handling even further and
2527 it should work now. Minor change to the prototype of function
2528 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2530 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Added new function into lib/silcutil/silcschedule.[ch]:
2533 silc_schedule_with_fd to select() a specified fd. The function
2534 returns after timeout expires or data arrives or goes. The
2535 function is used by packet routines to wait that all data is
2536 received from network.
2538 * Fixed data reading from network in lib/silccore/silcpacket.c.
2539 The code now assures that all data is read from the fd and then
2540 continues packet processing. This was a bug fix since the code
2541 used to drop some data in some circumstances.
2543 * Added new function into lib/silcclient/client.[ch]:
2544 silc_client_start_key_exchange to start key exchange after
2545 connection has been established to server. The code internally
2546 now uses this funtion but its main purpose was to provide it
2547 for applications that perform their own connecting. After
2548 application has created a connection it merely calls this
2549 function to start the key exchange between client and server.
2550 The library takes care of everything else after that.
2552 Updated also lib/silcclient/README to explain the usage of
2555 * Do not send to application information that connection has
2556 been established. Application gets notified it by connect
2559 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Applied cras's patch to add silc_schedule_one function. The
2562 function runs scheduler once and returns.
2564 * Fixed the scheduler after cras messed it up. The timeout
2565 handling works now as it's supposed to work.
2567 * Added into lib/silccore/ silcnotify.h to include notify
2568 message types support. Changed silc_server_send_notify*
2569 functions, in server.[ch], to support those new notify types.
2570 Added the support for the notify types into client library,
2571 as well. Added new notify client operation into ops.h in
2574 * Changed silc_server_packet_send_to_channel to send normal
2575 packets instead of just channel message packets. The function
2576 is now used to send the notify packets to channels. It is not
2577 used to send channel message packets anymore, as server never
2580 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2581 va_arg()s as it seems to require it nowadays. I guess, if SILC
2582 is compiled with older va_arg() the new code should work anyway.
2584 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Splitted core library. Core library (lib/silccore) includes
2587 now only SILC protocol specific core (and common) components.
2588 Created new utility library (lib/silcutil) that includes more
2589 generic purpose stuff. The stuff for util library was taken
2590 from the old core library. This was minor and easy split.
2592 * Created SILC Client Library (lib/silcclient) that includes
2593 implementation of the SILC client without user interface. This
2594 was major move from silc/ directory. The code has been changed
2595 so that it is transparent towards the user interface. The
2596 silc/ directory includes now the same user interface as before
2597 and it uses the new client library. Read lib/silcclient/README.
2598 Basicly, the client library performs everything else related
2599 to SILC except user interface handling. Also, configuration
2600 files are considered to be part of user interface and library
2601 does not handle them.
2603 This change also changed a lot of structures, function naming etc.
2604 Most important change was that SilcClientWindow object was
2605 renamed to SilcClientConnection in the client library. Created
2606 also new file lib/silcclient/ops.h. Also added new files
2607 silc/local_command.[ch] and silc/client_ops.[ch].
2609 All these changes were made to make it easier for user interface
2610 designers to create what ever user interface for the SILC client
2613 It is also expected that the server will be moved to lib
2614 directory as well and SILC Server Library will be created;
2615 sometimes in the future.
2617 * Removed Local commands from lib/silccore/silccommand.h as
2618 they are application specific and new client library does not
2619 handle any of those anymore.
2621 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2622 old client implementation in silc/.
2624 * Added support for callback functions in SILC_LOG_* macros.
2625 Application can now set its own callbacks that will be called
2626 instead of using the default functions that will always print
2627 the debug messages to stderr (or stdout). Also, debugging can
2628 now be disabled by setting silc_debug to FALSE and re-enabled by
2629 setting it to TRUE. Note, that logging will still work even
2630 if debugging is disabled.
2632 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2633 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2634 silc_log_reset_debug_callbacks.
2636 * To enable debugging in silc client one must give now -d
2637 option on command line.
2639 * Changed silc_schedule_init to automatically allocate task queues
2640 if they are not allocated before calling it.
2642 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added GMP 3.1 into math library.
2646 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2649 a channel in SILC network. The packet is used by servers and
2650 routers to notify other routers that user has left a channel.
2651 This little feature was missing until now. Added the feature
2652 to protocol specification as well.
2654 Added functions: silc_server_send_remove_channel_user and
2655 silc_server_remove_channel_user into server.[ch].
2657 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2658 lib/silccore/silcpacket.h. However, they are not implemented
2661 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Fixed joining to a channel and sending channel messages
2664 between server and router. The channel message sending should
2665 now work inside a cell.
2667 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed the private message sending between server and router.
2670 The private message sending should now work inside a cell.
2672 * Added silc_server_replace_id into server.[ch] to replace
2673 existing ID in the SILC network.
2675 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2676 and silc_idlist_replace_server_id into idlist.[ch] in server.
2678 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Fixed the server to server connections. Server can again now
2681 connect to router. Router to router connections probably does
2684 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Added dynamic protocol registering support. Now protocols can
2687 registered and unregistered on the fly. Patch by cras.
2689 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added lib/contrib directory to hold routines that some platforms
2692 don't have but are needed by SILC.
2694 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2695 into lin/contrib to provide getopt() and getopt_long() for
2696 those who don't have it.
2698 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Added AWAY command to client. When away message is set and
2701 client receives a private message packet the client automatically
2702 replies to the sender with the away message.
2704 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2705 bug seemed to be the cause of recent problems when compiling
2708 * Added version detection support to SKE protocol specification
2709 and added the new changes to the SKE implementation as well.
2710 There were other minor changes in the SKE protocol as well.
2712 Many changes in lib/silcske/silcske.[ch] and in
2713 lib/silcske/payload.[ch].
2715 * Added ^U functionality, clear input line. Patch from cras.
2717 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Mainly small bugfixes on core library. Fixed some debugging
2720 logging and buffer overflow in silclog.c.
2722 * Updated config.sub and config.guess on the distribution tree.
2724 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Added command lagging support in server. Client may execute
2727 commands now only once in two seconds.
2729 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Optimized packet reception. MAC computation and checking is now
2732 also more optimized. A lot previously duplicated code is now
2733 used as generic by both client and server.
2735 * Fixed key pair generation in clientutil.c
2737 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added into lib/silccore/silcbufutil.[ch] new function;
2740 silc_buffer_realloc.
2742 * Moved generic packet sending/encryption functions to
2743 lib/silccore/silcpacket.[ch] from client and server. Some
2744 rewriting of the functions.
2746 * Moved all generic packet reception/decryption functions to
2747 lib/silccore/silcpacket.[ch] from client and server. The
2748 packet processing is now much cleaner in both client and server.
2749 These were major changes in both client and server.
2751 * Created many common functions in server to do packet sending.
2752 Previously code were duplicated a lot, this has been removed
2755 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Rewrote major parts of the ID cache system. Don't know
2758 whether it is better now or not but at least the API is more
2761 * Major rewrite on ID cache stuff on client because of the ID
2762 cache API changes. Added idlist.c to client.
2764 * Also major rewrite on ID cache stuff on server as well.
2765 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2766 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2767 in hand, instead they are all put into the ID cache system now.
2768 All server_idlist_* routines uses ID cache now instead of
2769 traversing its own lists (those lists does not exist anymore).
2770 SilcIDList though still exists. Also, SilcXXXEntry's are
2773 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Finally made the SKE implementation compliant to the protocol
2776 specification. All mp integers are now binary encoded as
2777 opposed being HEX encoded.
2779 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2782 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2783 functions: silc_[encode/decode]_pem. Also added function
2784 silc_encode_pem_file to PEM encode with newlines ('\n') for
2787 * SILC public keys are now encoded either PEM or binary. Same
2788 option is for private keys as well. By default private keys
2789 are binary encoded and public keys PEM encoded. Silly HEX
2790 encoding were removed.
2792 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2793 function to create fingerprints.
2795 * Fixed a bug in SHA1; does not change the original data anymore.
2797 * Partly implemented INFO command on client and server side.
2798 Fixed CLEAR command. Changes to SERVER command; show current
2799 server(s) when giving command without arguments. Added
2800 VERSION command to client.
2802 * Added check to server that unregistered connections cannot
2803 execute commands (unless it is specificly allowed).

2807 * Fixed screen refresh.
2809 * Fixed channel joining bug from client. On some circumstances
2810 client tried to join to a channel it had already joined.
2812 * Added public key verification process into client's protocol.c.
2813 The client now verifies the public key from user and saves
2814 it into ~./silc/serverkeys/ directory.
2816 Added into: clientutil.[ch]: silc_client_verify_server_key.
2818 * Changed SKE protocol's silc_ske_initiator_finish function
2819 to accept callback function that verifies the received public
2820 key. Removed old silc_ske_verify_public_key function.
2822 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2825 silc_pkcs_private_key[_data]_set.
2827 * Made the password and public authentication more cleaner in
2828 server's protocol.c.
2830 * Removed historic and obsolete protocol `channel_auth' from
2831 both client and server.
2833 * Removed wrong way of sending command status messages from
2834 server to client in server's command.c. The old way violated
2835 protocol specification.
2837 Changes to silccore/silccommand.[ch]: removed
2838 silc_command_encode_status_payload -> not needed anymore,
2839 changed silc_command_encode_payload_va to accept extra
2840 argument on variable argument list. The argument type must
2841 now be provided to the function. Also, added new function:
2842 silc_command_encode_reply_payload_va which is same as
2843 normal command_encode_payload_va except command status type
2844 is provided as extra argument.
2846 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Added ~./silc directory handling. The directory includes the
2849 public and private keys for the client.
2851 Added silc_client_check_silc_dir, silc_client_create_identifier
2852 and silc_client_load_keys.
2854 * Implemented SILC protocol compliant public key. Added public
2855 and private key saving to and loading from files.
2857 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2858 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2859 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2860 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2861 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2863 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2864 silc_pkcs_load_[public/private]_key.
2866 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Added silc_server_get_route (route.[ch]) to get connection
2869 data for the fastest route for given ID.
2871 * Implemented INVITE command on client and server. The command
2872 were re-defined in the SILC Protocol Specification and the
2873 implementation now complies with the specification.
2875 * Implemented PING command on client and server.
2877 * Implemented NAMES command on client and server. The server side
2878 supports currently only normal server not router server yet.
2879 Some changes to NAMES definition in SILC protocol specification.
2881 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Implemented LEAVE command on client and server.
2885 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2886 again. This change was made to the protocol as well. Server
2887 should not violate the protocol specification anymore.
2889 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2892 was tested. SOCKS4 was not but should work anyway.
