1 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4 crashed since it did not handle the fact that there is no cipher
5 called "3" and didn't check the error condition. Now fixed.
7 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
8 flag. It can be used to send message requests.
10 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Implemented the RESTART command in the client.
14 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
15 notice type messages. Added notice printing to the user
18 * The channel keys are not re-generated if the channel's mode
19 is PRIVKEY, ie private key on the channel exists. Affected
20 files silcd/server.c and silcd/command.c.
22 * Fixed a little bug in channel message delivery when channel
23 private keys are set in the server. Affected file is
26 * Changed the setting on channel->on_channel = TRUE from the
27 silc_client_save_channel_key to the JOIN command reply. The
28 key payload is not received if the private channel key is set.
29 Affected file lib/silcclient/command_reply.c and the
30 lib/silcclient/client_channel.c.
32 * When the CMODE_CHANGE notify is sent and the channel private
33 key mode is removed the channel key must be re-generated in
34 other cells as well. Added this support for the router in the
35 silcd/packet_receive.c.
37 * Added new local command NOTICE to send notice message on
38 channel. Affected file silc/local_command.[ch].
40 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Added new local command ME to the client. It is used to send
43 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
44 some action. Affected file silc/local_command.[ch].
46 * Changed channel_message and private_message client operations
47 to deliver the message flags to the application. Added also
48 the `flags' arguments to the silc_client_send_channel_message
49 and silc_client_send_private_message functions. Affected file
52 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Redefined the Private Message Payload to support private message
55 keys and to support the new private message flags. Updated
56 the protocol specs. Flags makes it possible to have for example
59 * Added new type SilcPrivateMessagePayload and defined an API
60 for it in the lib/silcclient/silcprivate.[ch].
62 * Tested private message private keys successfully. Tested the
63 private message key set, unset and list commands with the new
66 * Redefined the Channel Message Payload to include the channel
67 message flags (equal with private message flags) to support
68 for example CTCP style messages.
70 * Defined some of the message (for channel and private message)
71 flags. Updated the protocol specs and added the flags to the
72 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
74 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Added SilcKeyAgreementStatus type to the key agreement routines
77 to indicate the current status and error if one occured.
78 The status types are defined in the lib/silcclient/silcapi.h.
80 * Added new local command KEY that is used to set and unset private
81 keys for channels, set and unset private keys for private messages
82 with remote clients and to send key agreement requests and
83 negotiate the key agreement protocol with remote client. The
84 key agreement is supported only to negotiate private message keys,
85 it currently cannot be used to negotiate private keys for channels,
86 as it is not convenient for that purpose.
88 * Fixed a minor pending callback setting bug in the function
89 silc_client_get_client_by_id_resolve, now the function works.
90 Affected file lib/silcclient/idlist.c.
92 * Added function silc_net_get_local_port to get local bound
93 port by socket. Added to lib/silcutil/silcnet.[ch].
95 * Added `sockets' and `sockets_count' fields to the SilcClient
96 object. They hold the sockets of the listenning sockets in
97 the client. Listenning sockets may be for example the key
98 agreement server. Affected file lib/silcclient/client.[ch].
99 Added functions the silc_client_add_socket and the
100 silc_client_del_socket. They are exported to the application
103 * Added ~./silc/clientkeys to support other client's public keys.
105 * Renamed verify_server_key client operation to verify_public_key
106 and added one argument to indicate the type of the connection
107 (server, client etc.).
109 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Added silc_server_connection_auth_request to handle the
112 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
113 silcd/packet_receive.[ch].
115 * Added silc_server_send_connection_auth_request into the
116 silcd/packet_send.c to send the connection auth request packet.
118 * Cleaned up the silcd/protocol.c a bit and fixed some memory
121 * Fixed the public key authentication in responder side in the
122 server. The `auth_data' pointer includes the SilcPublicKey
123 not the path to the public key. Affected file silcd/protocol.c.
125 * Implemented the public key authentication in the initiator side
126 in the server. Affected file silcd/protocol.c.
128 * Removed the [RedirectClient] config section from the server
129 configuration. Is not needed and I don't want to implement it.
131 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Cleaned up the CMODE command in the server. It now works
134 correctly and supports all the modes defined in the protocol.
135 Affected file is silcd/command.c.
137 * Added `hmac_name' field to the SilcChannelEntry in the server
138 to hold the default HMAC of the channel. It can be set when
139 creating the channel (with JOIN command). Affected files
142 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
143 type to indicate the change of the current cipher and hmac
144 on the channel. Client can safely ignore the <cipher> argument
145 (if it chooses to do so) since the CHANNEL_KEY packet will
146 force the channel key change anyway. The <hmac> argument is
147 important since the client is responsible of setting the new
148 HMAC and the hmac key into use.
150 * Fixed the CMODE command in the client library as well.
152 * Tested CMODE command in router environment successfully.
154 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Show the version of the remote client (or server) when connecting
157 to the server. It is logged to the log file. Affected file
160 * Fixed the KILLED notify handling in the client library. The
161 client must be removed from all channels when receiving the
164 Also, do not remove the client entry when giving the KILL
165 command but when the KILLED notify is received.
167 * Removed silc_idlist_find_client_by_nickname from the server.
168 Not needed anymore. Affected files silcd/idlist.[ch].
170 * Implemented the CHANNEL_CHANGE notify type handling to the
171 server. Affected file silcd/server.c.
175 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

178 notify between routers.
180 * Implemented the INVITE command correctly to the server.
182 * Implemented the INVITE notify type handling in the server.
184 * Implemented the INVITE command to the client library and on the
187 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Added function silc_server_get_client_resolve to find the
190 client entry by ID from all ID lists and then resolve it
191 (using WHOIS) if it cannot be found. Affected file is
194 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Implemented the BAN command to the client library.
198 * The JOIN command in the server now checks the invite list
201 * Changed the silc_command_reply_payload_encode_va and the
202 silc_command_payload_encode_va to support that if argument is
203 NULL it ignores and checks the next argument. Affected file
204 lib/silccore/silccommand.c.
206 * Added silc_server_send_notify_ban to send the BAN notify
207 type between routers.
209 * Chaned the silc_notify_payload_encode to support that if
210 argument is NULL it ignores and checks the next argument.
211 Affected file lib/silccore/silcnotify.c.
213 * Tested ban lists in router environment successfully.
215 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Implemented BAN command to the server, in silcd/command.[ch].
219 * Removed the BAN and INVITE_LIST modes from the CMODE command
222 * Added function silc_string_match to regex match two strings.
223 Affected files lib/silcutil/silcutil.[ch].
225 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Redefined parts of the SilcChannelEntry in the server to support
228 the new ban and invite lists.
230 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
232 * Redefined the INVITE command. The same command can be used to
233 invite individuals to the channel but also to manage the invite
234 list of the channel (to add to and remove from the invite list).
235 Updated the protocol specs.
237 * Added new command SILC_COMMAND_BAN that can be used to manage
238 the ban list of the channel. Updated the protocol specs.
240 * Removed the channel modes: the SILC_CMODE_BAN and the
241 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
242 in the CMODE command. The equivalent features are now available
243 using INVITE and BAN commands. Updated the protocol specs.
245 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
246 in the network about change in the current ban list. The notify
247 type is not used by the client.
249 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
250 support the invite lists.
252 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added new function silc_string_regexify that converts string
255 including wildcard characters into regex string that can
256 be used by the GNU regex library. Added into the file
257 lib/silcutil/silcutil.[ch].
259 Added silc_string_regex_combine to combine to regex strings
260 into one so that they can be used as one regex string by
261 the GNU regex library. Added into the file
262 lib/silcutil/silcutil.[ch].
264 Added silc_string_regex_match to match two strings. It returns
265 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
267 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Imported GNU regex to the soruce tree into lib/contrib.
270 Fixed some compiler warning from the regex.c.
272 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Fixed MOTD command in the server to work in router environment.
276 * Fixed the MOTD command in the client library to support
277 the server argument in the command.
279 * Added `nickname_len' argument to the silc_idlist_add_client
280 in the server, as the `nickname' argument may be binary data
283 * Added silc_idlist_get_channels to return all channels from
286 * Implemented LIST command to the server. Affected file is
289 * Implemented the LIST command to the client library and on the
292 * Added [<user count>] argument to the LIST command reply.
293 With private channels the user count is not shown.
295 * Updated TODO and README.
297 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * The client entry's data.registered must be TRUE even with
300 global client entry on global client list. The data.registered
301 is used to check whether the client is anymore in the network,
302 for example with WHOWAS command so it must be valid.
304 * Fixed the WHOWAS command in the server. It now actually works
305 in router environment. Added function into silcd/command_reply.c
306 silc_server_command_reply_whowas_save.
308 * Added silc_idlist_purge function to the silcd/idlist.c
309 to periodically purge the ID Cache.
311 * Fixed INFO command in the server. It works now in router
312 environment. Added <server name> argument to the INFO command
313 reply. Updated the protocol specs.
315 * Fixed minor bug in silc_idcache_purge to not purge if the
316 expire value is zero.
318 * Fixed various bugs in WHOIS and IDENTIFY command handling as
319 they were buggy because of the WHOWAS information.
321 * Fixed local command MSG to handle the async resolving of
322 the remote client properly. It used to fail the first MSG.
323 Affected file silc/local_command.c.
325 * Added `data_len' field to SilcIDCache context.
327 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Update TODO. Todo in commands in the server.
331 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
334 used by routers as broadcast packet to inform other routers
335 about the changed user mode.
337 Implemented the notify handling in the server. Affected file is
338 silcd/packet_receive.c. Added the function
339 silc_server_send_notify_umode to the silcd/packet_send.[ch].
341 * Added new generic Channel Payload and deprecated the New Channel
342 Payload. The New Channel Payload is now the generic Channel
345 * Added new argument `mode' to the silc_server_send_new_channel
346 as it is required in the Channel Payload now.
348 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
349 and created a new and real SilChannelPayload to represent the
350 new generic Channel Payload. Implemented the encode/decode
351 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
353 * Added silc_server_get_client_channel_list to return the list
354 of channels the client has joined for WHOIS command reply.
355 Affected file silcd/server.[ch].
357 * Implemented the channel list sending in the WHOIS command reply
358 in server and in the client.
360 Implemented the channel list displaying on the user interface
361 as well. Affected file silc/client_ops.c.
363 * Added silc_channel_payload_parse_list to parse list of Channel
364 Payloads. It returns SilcDList list of SilcChannelPayloads.
365 Client for example can use this function to parse the list of
366 channels it receives in the WHOIS command reply. The caller
367 must free the list by calling silc_channel_payload_list_free.
368 Affected files lib/silccore/silcchannel.[ch].
370 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Added one new argument <user mode> to the WHOIS command reply
373 to return the mode of the user in SILC. Updated the protocol
376 Implemented it to the server and client.
378 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
380 * Fixed the mode printing on the user interface on joining.
381 Affected file silc/client_ops.c.
383 * Implemented the UMODE command and user modes in general to the
384 client library and to the user interface.
386 * Implemented the UMODE command to the server.
388 * The server now sends UNKNOWN_COMMAND error status if client sends
389 unknown command. Affected file silcd/command.c.
391 * All server commands now handle the command identifier the right
392 way when sending the command reply to the client. The client can
393 use to identify the command replies with the identifier.
395 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Added silc_server_get_client_route to resolve the route to
398 the client indicated by the client ID. Affected file is
401 * Added silc_server_relay_packet as general function to relay
402 packet to arbitrary destination. This deprecates functions
403 like _send_private_message_key, _relay_notify etc. Affected
404 file is silcd/packet_send.[ch].
406 Removed silc_server_send_key_agreement,
407 silc_server_send_private_message_key and
408 silc_server_packet_relay_notify functions from the file
409 silcd/packet_send.[ch].
413 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
414 server. Affected file silcd/packet_receive.[ch].
416 * Implemented the KILL command to the client. Implemented the
417 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
418 Affected files lib/silcclient/command[_reply].c and
419 lib/silcclient/client_notify.c. Implemented the KILL notify
420 printing in the user inteface.
422 * Fixed a lot silc_parse_nick memory leaks from the client
423 library in the file lib/silcclient/command.c.
425 * Changed the silc_server_send_notify_on_channels's `sender'
426 argument from SilcSocketConnection to SilcClientEntry to
427 check the sender as entry and not as connection object and not
428 to send to the client provided as argument. The affected file
429 is silcd/packet_send.[ch].
431 * The notify packets that are destined directly to the client used
432 to not to be processed by the server. Now changed that and the
433 server processes all notify packets. After relaying the packet
434 to the client the notify packet is processed in the server.
436 * The silc_server_free_client_data now checks whether there is
437 pending outgoing traffic for the client and purges the data to
438 the network before removing the client entry.
440 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
443 an client is killed from the SILC Network. Updated the protocol
446 Added new function silc_server_send_notify_killed to the
447 silcd/packet_send.[ch].
449 * Added function silc_server_packet_relay_notify to relay notify
450 packets that are destined directly to a client. In this case
451 the server does not process the notify packets but merely relays
452 it to the client. Affected file silcd/packet_send.[ch].
454 Added also silc_server_packet_process_relay_notify to check
455 whereto relay the notify. Affected file is
456 silcd/packet_receive.[ch].
458 * Implemented the KILL command to the server.
462 * Added the backup schema desgined last fall to the protocol
463 specs for everyone to see. The specification is in the
464 *-spec-xx.txt draft and the packet type definitions for the
465 backup routers is in *-pp-xx.txt draft. Thusly, added also
466 new packet type SILC_PACKET_CELL_ROUTERS.
468 * A big security problem in the implementation discovered. The
469 signoff of an client did not cause new channel key generation
470 which it of course should've done. The channel keys must be
471 always re-generated when client leaves (or signoffs) the channel.
472 The silc_server_remove_from_channels funtion now handles
473 the channel key re-generation.
475 * Added `sender' argument to the silc_server_send_notify_on_channels
476 to not to send the client provided as argument. Affected file
477 silcd/packet_send.[ch].
479 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Implemented OPER and SILCOPER commands into the server and
484 * Added silc_auth_verify and silc_auth_verify_data to verify
485 the authentication directly from the authentication payload.
486 It supports verifying both passphrase and public key based
487 authentication. Affected file lib/silccore/silcauth.[ch].
489 * Added `hash' field to the SilcIDListData structure. It is the
490 hash negotiated in the SKE protocol. Affected file is
493 * Slight redesigning of the SilcAuthPayload handling routines.
494 Do not send SilcPKCS but SilcPublicKey as argument.
496 * Implemented the public key authentication support to the
497 serverconfig. The public key is loaded from the provided path
498 and saved as authentication data to void * pointer. Thus,
499 changed the unsigned char *auth_data to void *auth_data;
501 * Fixed SHUTDOWN command to send the reply before the server
502 is shutdown. :) Affected file silcd/command.c.
504 * Fixed fatal bug in CONNECT command. The hostname was invalid
505 memory and server crashed. Affected file silcd/command.c.
507 * Fixed fatal bug in CLOSE command. The server_entry became
508 invalid but was referenced later in the command. Affected file
511 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Fixed fatal bug in failure packet handling. Server ignored
514 the failure and thus crashed when it came.
518 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
521 that the command may be executed only once in (about) 2 seconds.
522 The old SILC_CF_LAG flag is same but allows command bursts up
523 to five before limiting.
525 Added the support for CF_LAG and CF_LAG_STRICT flags to the
526 server code. Various commands now includes the CF_LAG_STRICT
527 flag to disallow any kind of miss-use of the command.
529 * Fixed the silc_buffer_unformat to not to allocate any data
530 if the length of the data is zero. It used to allocate the
531 length + 1. Affected file lib/silcutil/silcbuffmt.c.
533 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Changed the format of AdminConnection configuration section
536 in the server. Added username of the admin to the format.
537 Affected files silcd/serverconfig.[ch].
539 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
540 to return admin configuration data by host, username and/or
543 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * Implemented WHOWAS command to the server. Added the functions:
547 silc_server_command_whowas_parse,
548 silc_server_command_whowas_send_reply,
549 silc_server_command_whowas_from_client and
550 silc_server_command_whowas_from_server
552 * Added <Client ID> argument to the WHOWAS command reply. Updated
553 the protocol specs accordingly.
555 * Implemented WHOWAS command and command_reply to the client
558 Implemented the WHOWAS printing on the user interface.
560 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Added new argument to the WHOWAS command reply, the real name.
563 It is an optional argument. Updated the protocol specs.
565 * Added SilcIDCacheDestructor callback that is registered when
566 the SilcIDCache is allocated. The callback is called when
567 an cache entry in the ID Cache expires, or is purged from the
568 cache. Added into lib/silccore/idcache.[ch].
570 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
571 to destruct the client entries when the cache entry expires.
572 Other ID Cache's in server and in the client library ignores
575 * If the ID Cache entry's `expire' field is zero then the entry
576 never expires. Added boolean `expire' argument to the
577 silc_idcache_add function in the lib/silccore/idcache.[ch].
578 If it is TRUE the default expiry value is used.
580 * Added silc_server_free_client_data_timeout that is registered
581 when client disconnects. By default for 5 minutes we preserve
582 the client entry for history - for WHOWAS command.
584 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Added support to the server to enforce that commands are not
587 executed more than once in 2 seconds. If server receives
588 commands from client more frequently, timeout is registered
589 to process the commands. Affected file silcd/command.c.
590 Added new function silc_server_command_process_timeout.
592 * Changed NICK_NOTIFY handling in client library to check that
593 if the client's nickname was changed, so there is no need to
594 resolve anything from the server.
596 * Removed error printing from the WHOIS and IDENTIFY commands.
597 If error occurs then it is ignored silently in the client library.
598 The application, however, may map the received error to
599 human readable error string. The application currently maps
600 the NO_SUCH_NICKNAME error to string.
602 * Made the command status message public to the application. Moved
603 them from lib/silcclient/command_reply.c to
604 lib/silcclient/command_reply.h. The application can map the
605 received command status to the string with the
606 silc_client_command_status_message function.
608 * Added check to the server to check that client's ID is same
609 as the Source ID in the packet the client sent. They must
612 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Added dist-bzip hook to the Makefile.am to make bzip2
615 compressed distributions.
617 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Server now enforces the maximum length for the nickname and
620 the channel as protocol specification dictates. 128 bytes for
621 nickname and 256 bytes for channel name.
623 * Moved the WHOIS printing to the application. The client libary
624 does not print out the WHOIS information anymore, the application
625 must do it. Renamed silc_client_command_reply_whois_print to
626 the silc_client_command_reply_whois_save.
628 The client's idle time is also sent to the application now, and
629 the idle is shown on screen.
631 * Added silc_client_command_reply_identify_save to save the
632 received IDENTIFY entries.
634 * Do not check for channel private keys in message sending and
635 reception if the channel does not have the PRIVKEY mode set.
636 Affected file lib/silclient/client_channel.c.
638 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
641 just surfaced after chaning the JOIN procedure.
643 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Added silc_client_get_clients_by_list to get client entries
646 from Client ID list, that is returned for example by JOIN
647 and USERS command replies. The application should use this
648 function for example when JOIN command reply is received to
649 resolve the clients already on the channel (library does not
650 do that anymore as USERS command reply is not used in the JOIN
651 procedure anymore). Affected files lib/silcclient/silcapi.h and
652 lib/silcclient/idlist.c.
654 * JOIN command reply and USERS command reply returns now SilcBuffer
655 pointers instead of unsigned char pointers when returning
656 the client list and mode list.
658 * Added <Client ID> argument to the JOIN command reply, mainly
659 for the server to identify for which client the command was
660 originally sent. Updated protocol specs accordingly.
662 * Added SilcDlist private_key pointer to the SilcChannelEntry
663 in the client to support the channel private keys. Affected
664 file is lib/silcclient/idlist.h.
666 * Added SilcChannelPrivateKey argument to the function
667 silc_client_send_channel_message so that application can choose
668 to use specific private ke if it wants to. If it is not provided,
669 the normal channel key is used, unless private keys are set.
670 In this case the first (key that was added first) is used
671 as the encryption key.
673 * Implemented the support for channel private key handling.
674 Implemented the following functions:
676 silc_client_add_channel_private_key,
677 silc_client_del_channel_private_keys,
678 silc_client_del_channel_private_key,
679 silc_client_list_channel_private_keys and
680 silc_client_free_channel_private_keys
682 Affected file lib/silcclient/client_channel.c.
684 * Added the support for the private keys in the channel message
685 sending and encryption and in the message reception and
686 decryption. Affected funtions are
687 silc_client_send_channel_message and silc_client_channel_message.
689 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Added SKE's key verify callback to the client library's
692 KE protocol context. Affected files lib/silcclient/protocol.[ch].
694 * Removed the statement that server (or router) must send USERS
695 command reply when joining to the channel so that the client
696 knows who are on the channel. Instead, the client list and
697 client's mode list is now sent in the JOIN command reply to the
698 client who joined channel. This is better solution.
700 * Added function silc_server_get_users_on_channel and function
701 silc_server_save_users_on_channel to the silcd/server.[ch].
703 * Removed function silc_server_command_send_users from the
706 * Do not show topic on the client library anymore. The topic is
707 sent in the command reply notify to the application and the
708 application must show the topic now.
710 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Added client searching by nickname hash into the IDENTIFY and
713 WHOIS commands in the server as they were clearly missing from
714 them. Affected file is silcd/command.c.
716 * Fixed a bug in private message receiving in the client library.
717 The remote ID was freed and it wasn't supposed, now it is
720 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Minor fix to the channel payload; allocate the data area, as it
723 needs to be of specific length.
725 * If the key agreement port is zero then the operating
726 system will define the bound port. Affected files are
727 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
729 * Added new function silc_channel_payload_decrypt into the file
730 lib/silccore/silcchannel.[ch].
732 * Moved the channel message etc, check from silc_packet_decrypt
733 to applications. The library calls now a generic
734 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
735 when the packet is either normal or special. This was done to
736 allow more wide range of checking that was not allowed when
737 the code was in library. Now applications can do virtually any
738 checks to the packet and return to the library the decision how
739 the packet should be processed. Affected files are
740 lib/silccore/silcpacket.[ch].
742 Added silc_server_packet_decrypt_check to the server and
743 silc_client_packet_decrypt_check to the client library.
745 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
746 to send with specified source and destination information.
748 * Channel message delivery between routers was broken after the
749 channel key distribution was fixed earlier. The channel key
750 was used be to distributed to other routers as well which is not
751 allowed by the protocol. Now this is fixed and channel keys
752 really are cell specific and the channel message delivery between
753 routers comply with the protocol specification.
755 * Fixed various commands in server to check also the global list
756 for the channel entry and not just the local list. The affected
757 file silcd/command.c.
759 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Added assert()s to buffer formatting and unformatting routines
762 to assert (if --enable-debug) when error occurs. Affected
763 file: lib/silcutil/silcbuffmt.c.
765 * Changed to auto-reconnect to check whether the remote host is
766 router and register the re-connect timeout if it is. It used
767 to check that whether we are normal server, but router must do
768 auto-reconnect with another router as well. Affected file
771 * Removed the [<key len>] option from CMODE command as the cipher
772 name decides the key length, nowadays. See the defined ciphers
773 from the protocol specification.
775 * Added [<hmac>] option to the CMODE command to define the HMAC
776 for the channel. Added SILC_CMODE_HMAC channel mode.
778 * Added [<hmac>] option for the JOIN command so that user can
779 select which HMAC is used to compute the MACs of the channel
782 * Added Hmac field to the Channel Message Payload. The integrity
783 of plaintext channel messages are now protected by computing
784 MAC of the message and attaching the MAC to the payload. The
785 MAC is encrypted. Now, it is clear that this causes some
786 overhead to the size of the packet but rationale for this is that
787 now the receiver can verify whether the channel message decrypted
788 correctly and also when private keys are set for the channel the
789 receiver can decrypt the packet with several keys and check from
790 the MAC which key decrypted the message correctly.
792 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
793 lib/silccrypt/silccipher.[ch].
795 * Added silc_hash_len to return the digest length into the
796 lib/silcrypt/silchash.[ch].
798 * Rewrote parts of Silc Channel Payload interface in the
799 lib/silccore/silcchannel.[ch]. The encode function now also
800 encrypts the packet and parse function decrypts it.
802 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Fixed a minor formatting bug in the SKE's key material processing.
805 It actually might have processed the keys wrong way resulting
808 * Redefined the mandatory HMAC algorithms and added new algorithms.
809 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
810 and hmac-md5 truncated to 96 bits. The mandatory is now
811 hmac-sha1-96. Rest are optional (including the one that used
812 to be mandatory). Rationale for this is that the truncated HMAC
813 length is sufficient from security point of view and can actually
814 make the attack against the HMAC harder. Also, the truncated
815 HMAC causes less overhead to the packets. See the RFC2104 for
818 * Added new [hmac] configuration section. The SKE used to use
819 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
820 is of course wrong. The official names that must be proposed in
821 the SKE are the ones defined in the protocol specification
822 (hmac-sha1-96 for example). The user can configure any hmac
823 using any hash function configured in the [hash] section. At
824 least, the mandatory must be configured.
826 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
828 * Added HMAC list to the SKE proposal list. It has now both
829 hash algorithm list and HMAC list. This makes the protocol
830 incompatible with previous versions. The SKE now seems to work
831 the way it is supposed to work, for the first time actually.
833 * Defined plain Hash algorithms to the protocol specification.
836 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Implemented support for key agreement packets into the server.
839 Added functions silc_server_key_agreement and
840 silc_server_send_key_agreement. Other than these functions,
841 server has nothing to do with this packet.
843 * Added support for private message key packets into the server.
844 Added functions silc_server_private_message_key and
845 silc_server_send_private_message_key.
849 * Changed the silc_[client|server]_protocol_ke_set_keys to be
850 called in the protocol's final callback instead in the END
851 protocol state. This makes a little more sense and in the same
852 time in client we can use the same protocol routines for normal
853 key exchange and to key agreement packet handling as well.
855 * Added to both client's and server's KE protocol context the
856 SilcSKEKeyMaterial pointer to save the key material. We will
857 bring the key material to the protocol's final callback by doing
858 this. The final callback must free the key material.
860 * Added SKE's packet_send callback into client's KE protocol
861 context so that the caller can choose what packet sending function
862 is used. This way we can use different packet sending when
863 doing normal SKE when doing key agreement packet handling (in
864 the key agreement packet handling we do not want to encrypt
867 * Implemented the responder side of the key agreement routines
868 in the client. The client can now bind to specified port and
869 accept incoming key negotiation. The key material is passed
870 to the application after the protocol is over.
872 * Implemented the processing of incoming Key Agreement packet
873 in the client. Added function silc_client_key_agreement to
876 * Implemented the intiator side of the key agreement routines
877 in the client. The client can now initiate key agreement with
878 another remote client. The key material is passed to the
879 application after the protocol is over.
881 * Created client_keyagr.c to include all the key agreement
884 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
885 SILC_TASK_CALLBACK except that it is not static.
887 * Created client_notify.c and moved the Notify packet handling
888 from the client.[ch] into that file.
890 * Created client_prvmsg.c and moved all private message and
891 private message key routines from the client.[ch] into that file.
893 * Create client_channel.c and moved all channel message and
894 channel private key routines from the client.[ch] into that file.
896 * Changed silc_client_get_client_by_id_resolve to resolve with
897 WHOIS command instead of IDENTIFY command, in the file
898 lib/silclient/idlist.c.
900 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Implemented the SKE's responder side to the Client library.
904 * When FAILURE is received to the protocol do not trust it
905 blindly. Register a timeout to wait whether the remote closes
906 the connection as it should do it, only after that process the
907 actual failure. This was changed to both client and server.
909 * Added client_internal.h to include some of the structures
910 there instead of client.h in lib/silcclient/.
912 * Added function silc_task_unregister_by_callback to unregister
913 timeouts by the callback function.
915 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Some "Incomplete WHOIS info" errors has been appearing on the
918 log files. Took away the entry->userinfo check from WHOIS
919 reply sending. The entry->userinfo is now " " if client did not
920 provide one. I thought this was fixed earlier but something
921 is wrong still. Let's see if the error still appears.
923 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Fixed a minor bug in the login when the channel key is
926 re-generated in the server. It used to generate the key in
927 wrong order and thus caused problems in the channel traffic.
929 * Fixed a minor bug in channel key distsribution after
930 KICK command. The key was not sent to the router even though
933 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Added silc_ske_process_key_material_data as generic routine
936 to process any key material as the SILC protocol dictates. The
937 function is used by the actual SKE library but can be used by
938 applications as well. This relates to the private message keys
939 and the channel private keys since they must be processed the
940 same way the normal SILC session keys. The protocol dictates
941 this. Affected files: lib/silcske/silcske.[ch].
943 Added also silc_ske_free_key_material to free the
944 SilcSKEKeyMaterial structure.
946 * Defined silc_cipher_set_key function to set the key for
947 cipher without using the object's method function. The affected
948 files: lib/silccrypt/silccipher.[ch].
950 * Implemented silc silc_client_add_private_message_key,
951 silc_client_add_private_message_key_ske,
952 silc_client_del_private_message_key,
953 silc_client_list_private_message_keys and
954 silc_client_free_private_message_keys functions in the
957 Added functions silc_client_send_private_message_key to send
958 the Private Message Key payload and silc_client_private_message_key
959 to handle incoming Private Message Key payload.
961 * Added Cipher field to the Private Message Key payload to set
962 the cipher to be used. If ignored, the default cipher defined
963 in the SILC protocol (aes-256-cbc) is used.
965 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Removed lib/silcclient/ops.h file.
969 Redefined parts of the SILC Client Library API. Created new
970 file silcapi.h that deprecates the ops.h file and defines the
971 published Client Library API. Defined also private message key
972 API and channel private key API into the file.
974 This is the file that the application must include from the
975 SILC Client Library. Other files need not be included by
976 the application anymore.
978 * Added new key_agreement client operation callback and also
979 defined the Key Agreement library API for the application.
981 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
984 is used by clients to request key negotiation between another
985 client in the SILC network. If the negotiation is started it
986 is performed using the SKE protocol. The result of the
987 negotiation, the secret key material, can be used for example
988 as private message key.
990 Implemented the Key Agreement payload into the files
991 lib/silccore/silauth.[ch].
993 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Redefined ciphers for the SILC protocol. Added some new ciphers
996 and defined the key lengths for the algorithms. Changed the
997 code accordingly. The default key length is now 256 bits.
999 * Fixed SKE key distribution function silc_ske_process_key_material
1000 when the key length is more than 128 bits. The default key
1001 length in SILC is now 256 bits.
1003 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1004 to indicate unsupported algorithm.
1006 * Renamed rijndael.c to aes.c and all functions as well.
1008 * Fixed a long standing channel key setting bug in client library.
1009 Weird that it has never surfaced before.
1011 * Fixed bug in channel deletion. If the entire channel is removed
1012 then it must also delete the references of the channel entry
1013 from the client's channel list as the client's channel entry and
1014 the channel's client entry share same memory.
1016 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Implemented CONNECT and SHUTDOWN commands in the client.
1020 * Implemented CLOSE command to the client.
1022 * Added the function silc_idlist_find_server_by_name into the
1023 files silcd/idlist.[ch].
1025 Added the function silc_idlist_find_server_by_conn into the
1026 files silcd/idlist.[ch].
1028 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1030 * DIE command was renamed to SHUTDOWN. Updated the both code
1033 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1034 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1036 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1039 * Added function silc_server_create_connection function to create
1040 connection to remote router. My server implementation actually
1041 does not allow router to connect to normal server (it expects
1042 that normal server always initiates the connection to the router)
1043 so the CONNECT command is only good for connecting to another
1046 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1049 or some other client was kicked from the channel.
1051 Implemented the handling of the notify type to both client
1054 Implemented silc_server_send_notify_kicked to send the KICKED
1055 notify. It is used to send it to the server's primary router.
1057 * Implemented the KICK command into server and client.
1059 * Added `query' argument to the silc_idlist_get_client function
1060 to indicate whether to query the client from server or not if
1063 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1064 to indicate that the client is not channel founder.
1068 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Removed the rng context from SilcPacketContext structure and
1071 changed that the packet routine uses the Global RNG API.
1073 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added support for quit message that client can "leave" on the
1076 channel when it quits the SILC. It is ditributed inside the
1077 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1079 Added silc_server_free_client_data that will take the
1080 signoff message as argument.
1082 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1084 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Updated parts of the protocol specification to keep it up
1089 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1092 payloads in one packet.
1094 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1095 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1096 use now the new List flag.
1098 * Also deprecated the following packet types: REPLACE_ID,
1099 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1101 * Added list support for Notify packet in server.
1103 * Added silc_server_send_notify_channel_change to send the
1104 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1105 the silc_server_send_replace_id.
1107 * Added silc_server_send_notify_nick_change to send the
1108 NICK_CHANGE notify type. Deprecates the function
1109 silc_server_send_replace_id.
1111 * Added silc_server_send_notify_join to send the JOIN notify type.
1112 Deprecates the function silc_server_send_new_channel_user.
1114 * Added silc_server_send_notify_leave to send LEAVE notify type.
1115 Deprecates the function silc_server_send_remove_channel_user.
1117 * Added silc_server_send_notify_cmode and
1118 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1119 types. Deprecates the silc_server_send_set_mode function.
1121 * Added SERVER_SIGNOFF notify type to indicate that server has
1122 quit. This means that all clients on the channel from that
1123 server will drop. This can be also used when netsplit happens.
1125 Deprecated REMOVE_ID packet type since it is not needed anymore
1128 Added silc_server_send_notify_server_signoff to send the
1129 SERVER_SIGNOFF notify type. Deprecates the function
1130 silc_server_send_remove_id.
1132 Added also silc_server_send_notify_signoff to send the
1133 SIGNOFF notify type.
1135 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1136 SILC protocol from this day on. Changed the protocol
1137 specification as well.
1139 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1140 notify type. It is used between routers to notify about
1141 topic changes on a channel.
1143 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1146 * Partly updated the protocol specification to comply with the
1147 changes now made. It is still though a bit outdated.
1149 * The JOIN notify type now takes one extra argument <Channel ID>.
1150 The packet used to be destined to the channel but now the
1151 JOIN type may be sent as list thus it is impossible to
1152 destine it to any specific channel. By adding this argument
1153 it is again possible.
1155 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Added CREDITS file. The CHANGES and CREDITS file will appear
1158 in the distribution as well.
1160 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1163 types in the server's silcd/packet_receive.c.
1165 * Implemented CMODE and CUMODE to work in router environment.
1167 * Fixed minor encoding and decoding buglet from the
1168 lib/silccore/silcmode.c.
1170 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1173 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1175 * Changed all SilcConfigServer* and silc_config_server* to
1176 SilcServerConfig* and silc_server_config*, respectively.
1179 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Associated the ID (client or server ID) to the Authentication
1182 Payload to avoid any possibility of forging. Updated the
1183 protocol specification and the code accordingly.
1185 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * The RSA key length is now save to the RsaKey context in the
1188 key generation process in lib/silccrypt/rsa.c. The key length
1189 is now used to figure out the maximum size of the block allowed
1190 to be encrypted/signed.
1192 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1193 is equivalent to the silc_mp_mp2bin but does not allocate any
1196 * Changed silc_mp_mp2bin API to take length argument. If it is
1197 non-zero then the buffer is allocated that large. If zero, then
1198 the size is approximated using silc_mp_sizeinbase, which however
1201 * Created Global RNG API which is global RNG that application can
1202 initialize. After initializing, any routine anywhere in the
1203 code (including library) can use RNG without allocating a new
1204 RNG object. This was done to allow this sort of use of the
1205 RNG in code that has no chance to allocate RNG object. All
1206 applications currently allocate this and many routines in the
1207 library use this. Affected file lib/silccrypt/silcrng.[ch].
1209 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1210 it to use the Global RNG API.
1212 * Defined Authentication Payload into protocol specification that
1213 is used during SILC session to authenticate entities. It is
1214 used for example by client to authenticate itself to the server
1215 to obtain server operator privileges.
1217 Implemented this payload into the lib/silccore/silcauth.[ch].
1218 Implemented also routines for public key based authentication
1219 as the new protocol specification dictates.
1221 Moved definitions of different authentication methods from
1222 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1224 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1225 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1226 silc_pkcs_verify_with_hash functions into the file
1227 lib/silccrypt/silcpkcs.[ch].
1229 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * The client entry's userinfo pointer must be always valid.
1232 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1233 will fail since it requires the userinfo. Now, the userinfo
1234 is allocated as "" if actual userinfo does not exist. Actually,
1235 it must exist and it is totally Ok to drop client connections
1236 that does not announce the userinfo. However, we will make
1237 this workaround for now.
1239 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1240 to return the remote port by socket.
1242 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1245 SILC_SERVER_PENDING_EXEC and added an new macro
1246 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1247 data or when error occurs while processing the pending command.
1249 Added new argument `destructor' into silc_server_command_pending
1250 and to the SilcServerCommandPending object. This destructor is
1251 now called after calling the pending callback or if error occurs
1252 immediately. If error occurs the actual pending callback won't
1253 be called at all - only the destructor. The destructor may be
1254 NULL if destructor is not needed.
1256 All this applies for client library code as well. Similar
1257 changes were made there as well for the pending commands.
1259 In the client, the application must now allocate the
1260 SilcClientCommandContext with the silc_client_command_alloc
1263 * Added reference counter to the SilcServerCommandContext. Added
1264 function silc_server_command_alloc and silc_server_command_dup
1267 Same type of functions added to the client library for the same
1270 * Removed the cmd_ident from IDListData away since it is now
1271 global for all connections. It is the command identifier used
1272 in command sending and with pending commands. The affected file
1275 * Added reference counter to the SilcSocketConnection objecet to
1276 indicate the usage count of the object. The object won't be
1277 freed untill the reference counter hits zero. Currently only
1278 server uses this, and client ignores it. The client must be
1279 set to use this too later. The affected files are
1280 lib/silccore/silcsockconn.[ch]. Added also the function
1281 silc_socket_dup to increase the reference counter.
1283 This was mainly added because it is possible that the socket
1284 is removed underneath of pending command or other async
1285 operation. Now it won't be free'd and proper DISCONNECTING
1286 flags, etc. can be set to avoid sending data to connection that
1287 is not valid anymore.
1289 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1290 the connection. After that it sets SILC_SET_DISCONNECTED.
1291 It is, however, possible that the socket data is not still freed.
1292 The silc_server_packet_process now checks that data is not
1293 read or written to connection that is DISCONNECTED. The socket
1294 get's freed when the reference counter hits zero.
1296 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Changed the client operation API: channel_message operation's
1299 `sender' is now the client entry of the sender, not the nickname
1300 and the `channel' is the channel entry, not the channel name.
1302 In the private_message operation the `sender' is now also the
1303 client entry of the sender not the nickname.
1305 Affected file is lib/silcclient/ops.h and all applications
1306 using the client operations.
1308 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Moved the calling of ops->connect() from connect_to_server_final
1311 into receive_new_id functin since that is the point when the
1312 client is actually allowed to send traffic to network. The
1313 affected file is lib/silcclient/client.c.
1315 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1318 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1319 (if needs broadcasting) instead of broadcasting the packets one
1320 by one which would make a burst in the network traffic.
1322 * Added `broadcast' argument to the functions in silcd/server.[ch]
1323 silc_server_create_new_channel[_with_id] to indicate whether
1324 to send New Channel packet to primary router.
1326 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Added new function into the silcd/server.[ch] files:
1329 silc_server_create_new_channel_with_id to create new channel with
1330 already existing Channel ID.
1332 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1333 lib/silccore/silcpacket.h. This packet is used t send list of
1334 Set Mode payloads inside one packet. Server uses this to set
1335 the modes for the channels and clients on those channels, that it
1336 announced to the router when it connected to it. The protocol
1337 specification has been updated accordingly.
1339 * The silc_server_new_channel did not handle the packet coming
1340 from normal server as it normally does not send that. However,
1341 when it announces its channels it does send it. Implemented
1342 the support for that.
1344 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1345 into the file lib/silccore/id.h.
1347 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Fixed memory leaks in the functions silc_idlist_del_client,
1350 silc_idlist_del_channel and silc_idlist_del_server in the file
1351 silcd/idlist.c. All of those leaked like a sieve.
1353 * Fixed some small memory leaks in the client's function
1354 silc_client_notify_by_server.
1356 * Added functions into silcd/server.c: silc_server_announce_clients,
1357 silc_server_announce_channels and silc_server_announce_server.
1358 These functions are used by normal and router server to announce
1359 to its primary router about clients, channels and servers (when
1360 router) that we own. This is done after we've connected to the
1363 These functions effectively implements the following packet types:
1364 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1365 and SILC_PACKET_NEW_ID_LIST.
1367 * Added new functions into the silcd/packet_receive.[ch]:
1368 silc_server_new_id_list, silc_server_new_channel_list and
1369 silc_server_new_channel_user_list to handle the incoming
1370 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1372 * Added support of changing Channel ID in the function
1373 silc_server_replace_id. If the server that announces a channel
1374 to the router already exists in the router (with same name but
1375 with different Channel ID), router is responsible to send
1376 Replace ID packet to the server and force the server to change
1377 the Channel ID to the one router has.
1379 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1380 client that the Channel ID has been changed by the router. The
1381 normal server sends this to the client. Client must start using
1382 the new Channel ID as the channel's ID.
1384 Implemented handling of this new type into lib/silcclient/client.c
1385 into the function silc_client_notify_by_server.
1387 * Added new function silc_idlist_replace_channel_id into the files
1388 silcd/idlist.[ch] to replace the Channel ID.
1390 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Call silc_server_command_identify_check always when processing
1393 the IDENTIFY command in silcd/command.c
1395 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1398 send keepalive packets. The packet can be sent by clients,
1399 servers and routers.
1401 Added function silc_socket_set_heartbeat into the file
1402 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1403 If not set, the heartbeat is not performed. The actual
1404 heartbeat is implemented in the low level socket connection
1405 library. However, application is responsible of actually
1408 Added silc_server_send_heartbeat to send the actual heartbeat
1409 packet into silcd/packet_send.[ch]. Server now performs
1410 keepalive with all connections.
1412 * Added silc_task_get_first function into lib/silcutil/silctask.c
1413 to return the timeout task with shortest timeout. There was a bug
1414 in task unregistration that caused problems. TODO has been
1415 updated to include that task system must be rewritten.
1417 * The client library will now resolve the client information when
1418 receiving JOIN notify from server for client that we know but
1419 have incomplete information.
1421 * Rewrote parts of silc_server_remove_from_channels and
1422 silc_server_remove_from_one_channel as they did not remove the
1423 channel in some circumstances even though they should've.
1425 * Encryption problem encountered in server:
1427 The LEAVE command used to send the Channel Key packet to the
1428 router immediately after generating it. However, the code
1429 had earlier sent Remove Channel user packet but not immediately,
1430 ie. it was put to queue. The order of packets in the router
1431 was that Channel Key packet was first and Remove Channel User
1432 packet was second, even though they were encrypted in the
1433 reverse order. For this reason, MAC check failed. Now, this
1434 is fixed by not sending the Channel Key packet immediately but
1435 putting it to queue. However, this is more fundamental problem:
1436 packets that are in queue should actually not be encrypted
1437 because packets that are sent immediately gets encrypted
1438 actually with wrong IV (and thus MAC check fails). So, packets
1439 that are in queue should be encrypted when they are sent to
1440 the wire and not when they put to the queue.
1442 However, the problem is that the current system has not been
1443 designed to work that way. Instead, the packet is encrypted
1444 as soon as possible and left to the queue. The queue is then
1445 just purged into wire. There won't be any fixes for this
1446 any time soon. So, the current semantic for packet sending
1449 o If you send packet to remote host and do not force the send
1450 (the packet will be in queue) then all subsequent packets to the
1451 same remote host must also be put to the queue. Only after the
1452 queue has been purged is it safe again to force the packet
1455 o If you send all packets immediately then it safe to send
1456 any of subsequent packets through the queue, however, after
1457 the first packet is put to queue then any subsequent packets
1458 must also be put to the queue.
1460 Follow these rules and everything works fine.
1462 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Added new function silc_server_remove_clients_by_server to
1465 remove all client entries from ID list when the server connection
1466 is lost. In this case it is also important to invalidate all
1467 client entires as they hold the invalid server entry. This
1468 fixes fatal bug when server has lost connection and will reconnect
1471 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Made some sanity checks to silc_server_daemonise like to check
1474 whether the requested user and group actually exists.
1476 * Added sanity check to SKE's silc_ske_responder_finish to check
1477 that the public and private key actually is valid.
1479 * Invalidate the client's nickname when receiving Replace ID
1480 packet and the Client ID is being replaced. This means that the
1481 server will query the nickname if someone needs it (client)
1484 * Sort the ID Cache in client library when the ID Cache data
1485 has changed (needs sorting).
1487 * Do not allow for SILC client to create several connections to
1488 several servers. The client does not support windows right now
1489 and generating multiple connections causes weird behaviour.
1491 Irssi-silc client does support windows and can handle several
1492 connections without problems, see: www.irssi.org and SILC plugin.
1494 * Fixed some places where client was added to the IDList. The
1495 rule of thumb is following (in order to get everything right):
1496 If the client is directly connected local client then the
1497 `connection' argument must be set and `router' argument must be
1498 NULL to silc_idlist_add_client function. If the client is not
1499 directly connected client then the `router' argument must
1500 bet set and the `connection' argument must be NULL to the
1501 silc_idlist_add_client function.
1503 * The funtion silc_server_packet_send_local_channel actually did
1504 not check whether the client was locally connected or not. It
1505 does that now. Fixed a bug related to LEAVE command.
1507 * Fixed Remove Channel User payload parsing bug in server's
1508 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1510 * The server's silc_server_save_channel_key now checks also the
1511 global ID list for the channel as it might not be in the local
1512 list. Fixed a bug related to LEAVE command.
1514 * Is this the end of the [<unknown>] buglet that has been lurking
1515 around for a long time? A little for loop fix in server's
1516 silc_server_command_whois_parse that is used by both IDENTIFY
1517 and WHOIS command. At least, this was a clear bug and a cause
1518 of one type of [<unknown>] buglet.
1520 * WHOIS and IDENTIFY commands call the function
1521 silc_server_command_[whois/identify]_check function even if
1522 we are not router server.
1524 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Added --with-gmp configuration option. If set the GMP
1527 is always compiled in the SILC source tree. If not set then
1528 it is checked whether the system has the GMP3 installed. If
1529 it has then the GMP won't be compiled (the system's headers
1530 and library is used), if it doesn't have it then the GMP is
1531 compiled in the SILC source tree.
1533 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Changed RSA private exponent generation to what PKCS #1
1536 suggests. We try to find the smallest possible d by doing
1537 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1538 not security fix but optimization.
1540 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Added new config entry [Identity] to fork the server and run
1543 it as specific user and group. A patch from Bostik.
1545 * Imported Dotconf configuration library into lib/dotconf.
1546 This will be used to create the SILC configuration files later.
1547 It will appear in the distsribution after this commit.
1549 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * A big code auditing weekend happening. Auditing code for
1552 obvious mistakes, bugs and errors. Also, removing any code
1555 Removed files for being obsolete:
1557 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1558 inline in the file lib/silcutil/silcbuffer.h)
1560 o lib/silcutil/silcbufutil.c (the header has inline versions)
1562 Changed code to fix possible error conditions:
1564 o The buffer formatting routines now check that the destination
1565 buffer really has enough space to add the data. This applies for
1566 both buffer formatting and unformatting
1567 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1568 unformatting was changed to accomodate following rules:
1569 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1570 sent to the function while XXX_*STRING will not allocate or copy
1571 the data into the buffer. Instead it sets the pointer from the
1572 buffer into the pointer sent as argument (XXX_*STRING used to
1573 require that the pointer must be allocated already). This change
1574 makes this whole thing a bit more consistent and more optimized
1575 (note that the data returned in the unformatting with XXX_*STRING
1576 must not be freed now). The routines return now -1 on error.
1578 o Tried to find all code that use buffer_format and buffer_unformat
1579 and added return value checking to prevent formatting and
1580 especially unformatting errors and possible subsequent fatal
1583 o Changed ske->x and ske->KEY to mallocated pointers in
1584 lib/silcske/silcske.h. Fixed possible data and memory leak.
1586 o Added return value checking to all *_parse* functions. Fixed
1587 many memory leaks as well.
1589 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1590 so that buffer overflows would not happen. All code now also
1591 checks the return value as it can fail.
1593 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Added reconnection support to server if the normal server looses
1596 its connection to the router (for example if router is rebooted).
1597 The server performs normal reconnection strategy implemented
1598 to the server. Affected file silcd/server.c.
1600 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1602 * Added new packet type SILC_PACKET_SET_MODE that is used to
1603 distribute the information about changed modes (for clients,
1604 channels and clients channel modes) to all routers in the
1605 network. Updated the protocol specification accordingly.
1607 Added functions into silcd/packet_send.c and
1608 silcd/packet_receive.c: silc_server_send_set_mode,
1609 silc_server_set_mode.
1611 Added new files silcmode.[ch] into lib/silccore that implements
1612 the encoding and decoding of Set Mode Payload. Added new type
1613 SilcSetModePayload. Moved the definitions of different modes
1614 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1616 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Oops, a little mistake in server's connection authentication
1619 protocol. The protocol is not ended with FAILURE but with
1620 SUCCESS if the authentication is Ok. :) Affected file is
1623 * Implemented NICK_CHANGE notify handling in server in the file
1624 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1625 the local clients on the channel. After the changing nickname
1626 in router environment snhould work and the [<unknown>] nickname
1627 should appear no more.
1629 The silc_server_replace_id function that receives the Replace ID
1630 payload now sends the NICK_CHANGE notify type also in the file
1631 silcd/packet_receive.c
1633 * Changed WHOIS and IDENTIFY command to support the maximum amount
1634 of arguments defined in protocol specs (3328 arguments). This
1635 fixed a bug that caused problems when there were more than three
1638 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Added extra parameter, command identifier, to the
1641 silc_client_send_command so that explicit command identifier
1644 Changed that ID list routines uses specific command identifier
1645 when sending WHOIS/IDENTIFY requests to the server so that they
1646 can be identified when the reply comes back.
1648 Affected files lib/silcclient/command.[ch],
1649 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1651 * Added `sender' argument to silc_server_packet_send_to_channel
1652 to indicaet the sender who originally sent the packet to us
1653 that we are now re-sending. Ignored if NULL. Affected file
1654 silcd/packet_send.[ch].
1656 * Added some server statistics support in silcd/server_internal.h
1657 SilcServerStatistics structure and around the server code. Also
1658 send some nice statistics information when client is connecting
1661 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Fixed channel ID decoding in server's JOIN command reply in
1664 silcd/command_reply.c
1666 * Fixed braodcasting of replace ID payload to not to send it if
1667 we are standalone server in silcd/packet_receive.c.
1669 * Fixed all channel message sending routines to not to send
1670 packets to clients that has router set, since they are routed
1671 separately in the same function earlier. Affects file
1672 silcd/packet_send.c and all channel packet sending functions.
1674 * In USERS reply, res_argv[i] are not allocated, the table
1675 is allocated. Thus changed that free the table, not its
1678 * In server's whois_check and identify_check if the client is
1679 locally connected do not send any WHOIS commands - they are not
1682 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Fixed some minor bugs in client when sending WHOIS command. The
1685 arguments was in wrong order.
1687 * Removed statis function add_to_channel from server in
1688 silcd/command.c that was previously used with the joining but
1691 * Tested USERS command in router environment successfully with two
1692 routers, two servers and two clients.
1694 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Reorganized the USERS command and command reply in client library
1697 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1698 When the command is given by user we register a pending command
1699 callback that will reprocess the command after the reply has been
1700 received from the server. When reprocessing the packet we then
1701 display the information. Thus, the USERS information is displayed
1702 now in the command callback instead of in the command reply
1703 callback. The processing of the command is same as previously
1704 when server has sent the command reply in the JOINing process.
1706 * Added to USERS command in silcd/command_reply.c to join the client,
1707 we didn't use to know about, to the channel after we've created
1708 a client entry for it. Also, for clienet we did know already still
1709 check whether it is on the channel or not and add it if not.
1711 * Removed silc_server_command_join_notify as the function and its
1714 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Changed the client's pending command handling to the same as the
1717 server's pending command handling. It is also now possible to
1718 execute command reply functions from other command reply
1719 function as the function callbacks for commands and command
1720 replies are one and same. The pending commands are not static
1721 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1722 in client connection context. Thus, pending commands are server
1723 connection specific as it is convenient.
1725 Changed the function silc_client_command_pending and
1726 silc_client_command_pending_del and added new function
1727 silc_client_command_pending_check. Removed the
1728 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1731 * Added cmd_ident, current command identifier, to the client
1732 connection context in lib/silcclient/client.h to keep track on
1733 command identifiers used in command sending. Client's command reply
1734 function handling now supports the mandatory command identifiers.
1736 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1737 funtions in client to fully support pending command callbacks.
1739 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1740 as one of the arguments to the application in the command reply
1743 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1744 before first releasing SILC but came back. Now it is removed again
1745 and should come back nomore. The FORWARDED flag was used only
1746 by the JOINing procedure by forwarding the command packet to router.
1747 Now, the JOINing procedure has been changed to more generic (due
1748 to various router environment issues) and FORWARDED is not needed
1749 anymore for anything. The protocol specification is yet to be
1752 Now, removed silc_server_packet_forward from server and the flag
1753 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1755 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Renamed NAMES command to USERS command. The NAMES was named that
1758 due to historical reasons. Now it is renamed. Also, rewrote
1759 parts of the USERS command. The nickname list is not sent anymore
1760 by the server. Only Client ID and mode lists are sent in the USERS
1761 command. Changed this also to the protocol specification.
1763 The client now resolves the names and stuff after it receives
1764 the USERS list from the server when joining to the channel.
1766 * WHOIS and IDENTIFY commands has been changed to support multiple
1767 Client ID's per command. One can now search for multiple users
1768 in the network by sending only one WHOIS or IDENTIFY command.
1769 Changed the code and the protocol specifications.
1771 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1772 uses silc_server_command_whois_parse to parse the request. */
1774 * If normal server, do not parse the WHOIS and IDENTIFY requests
1775 before sending it to the router. Saves some time.
1777 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Fixed JOIN command on client library. Wrong number of arguments
1780 used to crash the client.
1782 * Added silc_server_channel_has_global function to check whether
1783 channel has global users or not.
1785 * Added silc_server_channel_has_local function to check whether channel
1786 has locally connected clients on the channel.
1788 * The silc_server_remove_from_one_channel now checks whether the
1789 channel has global users or not after given client was removed from
1790 the channel. It also checks whether the channel has local clients
1791 on the channel anymore. If it does not have then the channel entry
1792 is removed as it is not needed anymore.
1794 * The silc_server_notify now checks on JOIN notify whether the joining
1795 client is one of locally connected or global. If it is global then
1796 the channel has now global users on the channel and that is marked
1797 to the channel entry. Also, it now saves the global client to
1798 global list who is joining and JOINs it to the channel. This is
1799 for normal server, that is.
1801 Changed silc_server_send_notify_on_channel,
1802 silc_server_packet_relay_to_channel and
1803 silc_server_packet_send_to_channel check if we are normal server
1804 and client has router set (ie. global client) do not send the
1805 message to that client, as it is already routed to our router.
1807 * Implemented LEAVE notify type handling in silc_server_notify
1810 * Tested LEAVE command in router environment successfully. Tested
1811 with two routers, two servers and two clients.
1815 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1817 * Implemented SIGNOFF notify type handling in silc_server_notify
1820 * silc_server_remove_id now removes the client entry from all channels
1821 it has joined and thusly sends SIGNOFF notify type.
1823 * Rewrote the NAMES list generation in server by removing two excess
1824 loops. The lists are created now inside one loop.
1826 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1828 * silc_server_remove_channel_user checks now also global list
1829 for channel and client.
1831 * silc_server_new_channel_user checks now both local and global
1832 list for channel and client. Fixed a bug in client id decoding.
1833 Used to decode wrong buffer.
1835 * silc_server_channel_message checks now both local and global
1836 list for channel entry.
1838 * Tested channel joining (hence JOIN) in router environment
1839 successfully. Tested with two routers, two servers and two
1842 * Tested channel message sending in router environment successfully.
1844 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Added silc_server_save_channel_key into server.[ch] to save the
1847 received channel key in Channel Key payload processing. It is
1848 also used in JOIN command reply handling.
1850 Equivalent function silc_client_save_channel_key added into
1851 client.[ch] into client library.
1853 * Changed JOIN command reply to send information whether the channel
1854 was created or not (is existing already) and the channel key
1855 payload. Changed protocol specs accordingly.
1857 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1858 the request was sent by ID and not by nickname. Crashed on
1861 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1864 now correctly save the received data.
1866 * silc_server_free_sock_user_data now notifies routers in the
1867 network about entities leaving the network.
1869 At the same time implemented functions silc_server_remove_id
1870 and silc_server_send_remove_id to receive and send REMOVE_ID
1871 packets. The packet is used to notify routers in the network
1872 about leaving entities. The ID removed will become invalid in
1875 * Added function silc_idlist_del_server into server. Removes and
1876 free's server entry from ID list.
1878 * silc_server_private_message function now checks, if we are router,
1879 that the destination ID really is valid ID, naturally.
1881 * In router when NEW_ID packet is received (for new client) the
1882 hash of the Client ID is saved in the ID Cache but the
1883 client->nickname is set to NULL, instead of putting the hash
1886 IDENTIFY command now also checks that client->nickname must be
1887 valid. If it is not if will request the data from the server who
1888 owns the client. Added new function
1889 silc_server_command_identify_check.
1891 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1892 to set the command to already allocated Command Payload.
1894 * Tested private message sending in router environment with two
1895 routers, two servers and two clients. Fixed minor bugs and now
1898 * Fixed segfault from client's NAMES command. Used to crash if
1901 * Forwarded packets must not be routed even if it is not destined
1902 to the receiver. Changed server code comply with this.
1904 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Added `require_reverse_mapping' boolean value to ServerParams
1907 structure. If TRUE (not default) the server will require that
1908 the connecting host has fully qualified domain name.
1910 If the reverse mapping is not required and hostname could not be
1911 found the IP address is used as hostname.
1913 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Implemented version string checking to both client and server.
1916 The check is incomplete currently due to the abnormal version
1917 strings used in development version of SILC.
1919 * Changed all command functions in server to use the new
1922 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Changed char *data to unsigned char *data in ID Cache system to
1925 support binary data as ID Cache data. Changed code to support
1926 binary data in lib/silccore/idcache.c.
1928 * Renamed silc_server_packet_relay_command_reply to
1929 silc_server_command_reply as it is normal packet receiving
1930 function. Rewrote the function to accept command replys for
1931 servers and not only for clients.
1933 * Mark remote router always as registered server if we are connecting
1934 to it. Otherwise, commands sent by the router to us are ignored.
1936 * All ID List find routines now returns the ID Cache Entry pointer
1937 as well if requested.
1939 * WHOIS command works now in router environment, tested with two
1940 routers, two servers and two clients.
1942 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1943 in router environment (as it is almost equivalent to WHOIS) but
1944 hasn't been tested thoroughly. Added new functions:
1946 silc_server_command_identify_parse
1947 silc_server_command_identify_send_reply
1948 silc_server_command_identify_from_client
1949 silc_server_command_identify_from_server
1951 * Disabled route cache adding because adding two different ID's with
1952 same IP replaces the old cache entry thus giving wrong route.
1953 The entry->router->connection is always the fastest route anyway
1954 so route cache may not be needed. Of course, new routes maybe
1955 established after receiving the ID when the entry->router->connection
1956 might not be anymore the most optimal.
1958 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Add route cache for received ID for fast routing.
1962 * Added silc_server_packet_route to route received packet on router
1963 that is not destined to us.
1965 * Renamed silc_server_get_route to silc_server_route_get.
1967 * Added id_string and id_string_len fields into SilcServer to
1968 include encoded ServerID for fast comparing without excess
1969 encoding of the ID's.
1971 * Cleaned up WHOIS command on server side. Added following static
1974 silc_server_command_whois_parse
1975 silc_server_command_whois_check
1976 silc_server_command_whois_send_reply
1977 silc_server_command_whois_from_client
1978 silc_server_command_whois_from_server
1980 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1981 arguments in command replies. All command functions should be
1982 updated to use this macro.
1984 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Minor typo fixes on command reply handling on server.
1988 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Added silc_server_command_add_to_channel internal routine to add
1991 the client to the channel after router has created the channel and
1992 sent command reply to the server.
1994 * Added generic silc_server_send_command to send any command from
1997 * Use static buffer with ID rendering instead of duplicating data.
1999 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Fixed a channel user mode bug when joining to a channel server gave
2002 everybody channel founder rights, oops.
2004 * We mark ourselves as the router of the incoming server connection
2005 if we are router ourselves. This way we can check in some packet
2006 sending functions whether it is locally connected server. For
2007 incoming router connections we put NULL.
2009 * For router sending packets locally means now always sending the
2010 packet cell wide; to local clients and local servers. For normal
2011 server sending packet locally means sending it to only local
2014 * Fixed the JOIN command to really work in router environment. If the
2015 channel is created it is always created by the router. Router is
2016 also responsible of making the initial joining to the channel,
2017 sending JOIN notify to the sending server and distributing
2018 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2019 does not exist server doesn't do anything else but forward the
2020 command to the router which performs everything.
2022 * Added silc_server_send_channel_key function to send the Channel Key
2025 * Added silc_server_create_channel_key to create new channel key. The
2026 channel key is now re-generated everytime someone joins or leaves
2027 a channel, as protocol dictates. Note: channel->key_len is the
2030 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2033 packet_receive.[ch] to separate packet sending and receiving
2034 routines. The server.[ch] now includes everything else including
2035 actual packet processing (writing and reading data) and other
2038 Renamed silc_server_private_message_send_internal to
2039 silc_server_send_private_message. The routine is still though
2040 used only to relay private messages as server does not send
2041 private messages itself.
2043 Renamed silc_server_new_channel to silc_server_create_new_channel
2044 and added new function sicl_server_new_channel that handles the
2045 incoming New Channel packet. Added also new sending function
2046 silc_server_send_new_channel to send New Channel Payload.
2048 * Added new function silc_server_notify to process incoming notify
2049 packet to the server/router. Server may then relay the notify
2050 to clients if needed.
2052 * Added new function silc_server_new_channel_user to process incoming
2053 New Channel User packet. Router will redistribute the packet and
2054 send JOIN notify to its local clients and locally connected servers
2055 if needed. Normal server will send JOIN notify to its local client
2056 on same channel when received this packet. Added also corresponding
2057 sending function silc_server_send_new_channel_user to sent the
2060 * Added boolean route argument to send_notif_to_channel and
2061 packet_send_to_channel functions to attempt to route the packet
2062 if it is TRUE and send only locally if it is FALSE.
2064 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * silc_server_replace_id now broadcasts the received replace ID
2067 packet if it is not broadcast packet already. The router must
2068 broadcast to inform other routers about changed ID.
2070 * Added backpointer to server's router into SilcServer context in
2071 silcd/server_internal.h.
2073 * Fixed silc_server_packet_broadcast to send correct broadcast
2076 * The channel key is now distributed to the local client as soon
2077 as it is received from the router (in router environment) so that
2078 no other packet may be sent for the channel until client has
2081 * silc_server_remove_channel_user now broadcasts the received
2082 Remove Channel User packet if it is not broadcast packet already.
2083 The router must broadcast to inform other routers about removed
2086 * Added users field into SilcPacketContext that is a reference count
2087 of the context. One can increase the reference count by calling
2088 silc_packet_context_dup which is now changed to just increase the
2089 reference count instead of duplicating the data. The reference
2090 count is decresed by calling silc_packet_context_free that will
2091 free the data after the reference count hits zero.
2093 For now on the packet context and everything allocated into it
2094 (including the raw packet from network) must be freed by calling
2095 the new silc_packet_context_free function. Added also new function
2096 silc_packet_context_alloc that must be used now to allocate the
2097 context. This also means that if a routine is asynchronous from
2098 silc_[client/server]_packet_parse_type the packet context must
2099 be duplicated by calling silc_packet_context_dup. Otherwise it
2100 gets free'd after silc_[client/server]_packet_parse_type returns.
2101 Also, one must remember that if packet is duplicated then its
2102 reference count must be decresed by calling the free function as
2103 many times as it was duplicated.
2105 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2106 from both client and server.
2108 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Made joining to a channel working in router environment.
2112 * Cleaned up JOIN command on server side and create function
2113 silc_server_command_join_channel internal routine to make the
2116 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Changed silc_command_pending list to SilcDList. Also, added
2119 `ident' field to SilcServerCommandPending structure to identify
2120 the reply and to call correct callback.
2122 Added silc_server_command_pending_check function to replace the
2123 corresnponding macro. The silc_command_pending list is not
2126 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2127 to set identifier to previously allocated Command Payload. It
2128 is used to set identifier for command when resending Command
2131 * Added silc_command_payload_encode_payload to encode Command
2132 Payload buffer from SilcCommandPayload structure.
2134 * Added silc_argument_payload_encode_payload to encode Argument
2135 payload buffer from SilcArgumentPayload structure.
2137 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Changed WHOIS command to support router connection on server side.
2140 The whois request is always sent to router unless the server is
2141 standalone server. After server has received the reply from the
2142 router will it send the reply to the client.
2144 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2145 broadcast received broadcast packet. The function is used only
2146 by router. The broadcast packet is always sent to the router's
2149 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2150 render given ID to printable string, for log files for example.
2152 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Made basic router to router connections working. At least they
2155 can now connect to each other but nothing really works the way
2156 they are supposed - yet.
2158 * Added new initiator token to RouterConnection configuration
2159 file in silcd/serverconfig.[ch]. It is used to tell whether we
2160 are the initiator to the remote router or whether we'll expect
2161 the other end to connect.
2163 * Moved registering of listener task to silc_server_init, hence
2164 the server starts listenning as soon as it is run, even if it
2165 does not have connections to other routers. Let's see how well
2168 * Changed default connection retry timeouts for more suitable in
2171 * Removed cipher and such arguments from silc_idlist_add_client
2172 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2173 Added new function silc_idlist_add_data to add the keys and stuff
2176 * Added SilcIDListData structure and added it to SilcClientEntry
2177 and SilcServerEntry as their first field in the structure. This
2178 way we can explicitly cast the ID entries to the SilcIDListData
2179 structure and get common data for the entries. In past, we had
2180 to first check what type of connection it is and then cast it to
2181 correct ID entry type. Now, we can directly cast the opaque
2182 pointer to the SilcIDListData (no matter what ID entry it actually
2183 is) and get the data needed.
2185 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2188 in some circumstances even if threre were timeout tasks, though not
2189 IO tasks, but tasks anyway. Now fixed.
2191 * Defined SilcServerConnection structure to hold connection specific
2192 stuff about directly connected servers and routers. The definition
2193 is currently in silcd/server_internal.h. I thought about having
2194 a bit more important role fro this struct but for now it is used
2195 only when connecting to other server (or router actually).
2197 * Added connecting retry support in server when connecting to
2198 router(s). The retry feature implement exponential backoff
2199 algorithm. Also, added SilcServerParams structure to hold default
2200 parameters for server. For now, it include these retry settings
2201 and are hard coded. After server is moded to be as Silc Server
2202 Library this structure will be more important.
2204 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Changed client librarys channel->clients table to SilcList and
2207 changed code accordingly.
2209 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Changed client's channel table to SilcList and changed code
2212 accordingly. Also changed SilcChannelClientEntry to include back-
2213 pointer to the channel so that client entry can use that structure
2214 as list as well and we have fast cross-reference to the channel.
2215 This change dramatically decreased the complexity of channel
2216 handling with client entry and vice versa (removed one extra
2217 loop when searching for channel entry from many functions).
2219 * Changed server->sim from table to SilcDList and changed code
2222 * NAMES command can now be used from user interface. It will show
2223 the user list on the channel, neatly.
2225 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2226 Code now saves realname of the user if it becomes available.
2228 * Renamed configure.in to configure.in.pre and made ./prepare
2229 script to automatically add correct version string to
2230 configure.in which it creates from configure.in.pre.
2232 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * NAMES command reply now shows users mode with the nickname when
2237 * Moved silc_client_ch[u]mode[_char] functions from
2238 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2239 place sucks, they are utility functions and should be in some
2242 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2244 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2247 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Added TRQ (efficient deque and list library) into lib/trq. This is
2252 a very good list library that is currently used in the SILC. Defined
2253 SilcList API over the library because I didn't like the API very
2254 much. See lib/trq/silclist.h for the API and examples of how to
2255 use the API. Fixed various places in the code to use the new
2256 SilcList API. The SilcList is meant for lists that has a structure
2257 already defined as a list. It is not suitable to add just some
2258 context to the list (in TRQ, the context is the list actually).
2260 So, I defined SilcDList that can be used for the purpose where
2261 predefined list structure does not exit. This can be used as
2262 such list. Now some context just can be added to the SilcDList.
2263 Currently this list is not used in the SILC just yet, though there
2264 are a lot places where this can replace dynamically allocated
2265 tables and I will fix these places, later, to use SilcDList.
2266 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2267 and use TRQ internally).
2269 Also fixed some annoying warning messages that the original TRQ
2270 code generated. Also minor changes to TRQ's Makefile.in.
2272 * Added support for querying by Client ID to both WHOIS and
2273 IDENTIFY commands into server, as required by the protocol.
2275 * Removed method function pointers from SilcBuffer structure. They
2276 weren't used to anything and just increased the context size for
2277 no good reason. This change also made silc_buffer_alloc and
2278 silc_buffer_free functions inline functions.
2280 * Disabled command flooding detection support until it's fixed so
2281 that it accepts commands in but does not execute them more than once
2284 * Added silc_net_localhost(), to return local hostname, into
2285 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2286 that must be initialized before calling silc_client_init.
2288 * Added new function: silc_server_send_notify_on_channels to send
2289 notify messages to all channels client has joined. It is assured
2290 that the message is sent only once per client.
2292 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2293 lib/silcutil/silcutil.[ch] as silc_format function. The new
2294 function is generic and is used by server as well, not only by
2295 the logging routines.
2297 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2298 the provided version string was not acceptable. Added new function:
2299 silc_ske_check_version into lib/silcske/silcske.h. The function
2300 must be implemented by the application (client or server) and it
2301 does not reside in the SKE library. The function checks the version
2302 string remote end sent.
2304 * Added back pointers (to opaque context and to SilcSocketConnection)
2305 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2307 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2308 duplicate packet context structure.
2310 * Changed `notify' client operation to send same arguments as client
2311 receives from server except for ID's. ID's are mapped to correct
2312 ID entry and that is returned. Also, if channel entry is not sent
2313 by server but the notify is for channel the channel entry is sent
2314 to application (otherwise application doesn't know that it is for
2315 channel (library gets it from packet's Destination ID)).
2317 * Added silc_client_remove_from_channels into client library to
2318 remove a client from all channels it has joined to. Used when
2319 received SIGNOFF notify from server. Added also new function
2320 silc_client_replace_from_channels to replace old ID entry with
2321 new ID entry on all channels. Used when received NICK_CHANGE
2324 * Fixed ID Cache list handling in silc_idlist_get_client in
2325 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2326 to get (or query) client by ID.
2328 * Updated TODO list.
2330 * Added connection authentication status message defined by the
2331 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2332 support for these into the code in client and server side.
2334 * Added generic function silc_client_send_command to send any command
2335 with variable argument list. Application should use this function
2336 to send commands if the command functions provided by the library
2337 does not suite for the application's user interface needs.
2339 * Added new `failure' client operation. Application is notified about
2340 received failure packet if client is executing a protocol. In this
2341 case the protocol's execution has failed.
2343 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2344 is required by the protocol.
2346 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2347 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2350 * Added status flag to SilcSKE object to indicate realtime status
2351 of the SKE protocol.
2353 * Application receives now exactly same command reply arguments as
2354 the library receives from server. However, if ID is received the
2355 corresponding ID entry is returned to the application (eg. Client
2356 ID is mapped to correct SilcClientEntry entry and that is returned).
2357 Changed command_reply client operation due to this change.
2359 * Changed all ID's in commands and in command replys as ID Payloads.
2360 Change affected both client and server side codes.
2362 All ID's sent in SILC network (with execption of ID's in SILC
2363 Packet header) are sent in ID Payload to support variable length
2366 * Server now notifies nick changes and notifies all clients on
2367 the channels about the new nickname (about the new Client ID,
2370 * Implemented CMODE command to change channel modes. Supports all
2371 channel modes defined by the protocol specs except ban and invite
2372 lists. (Also, private channel key mode is supported but support for
2373 setting private channel key in client is missing, thus, this mode
2374 has no effect on client side (except that server requires that the
2375 client uses private channel key and normal channel traffic does not
2378 Also, invite mode works per se, but INVITE command does not work
2379 yet correctly, so you can set channel as invite only channel but
2380 inviting clients to the channel does not work (it is yet to be
2381 thought what's the best way to do it).
2383 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2384 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2385 Implemented CUMODE command to change user's mode on the channel.
2386 Supports all modes defined by the protocol specs.
2388 * Added NAMES command reply to return users modes on the channel.
2390 * Removed unnecessary and slow ciphers from lib/silccrypt.
2392 * Set SO_KEEPALIVE option to connection sockets by default.
2394 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2396 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2397 redefined the Notify Payload into protocol specs.
2399 * Added silc_id_payload_parse_id to get ID directly from raw
2402 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2405 accept searching by Client ID as well.
2407 * Added support for LEAVE and SIGNOFF notify types in client library.
2409 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2410 to parse ID Payload from raw data.
2412 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Added flags parameter into silc_ske_assemble_security_properties
2415 function in lib/silcske/silcske.[ch].
2417 * Changed notify client operation to fit better for notify messages
2418 sent by server. The notify payload received from server is now
2419 passed to the application (after parsing it to SilcNotifyPayload).
2420 It is application's responsibility to retrieve the arguments
2421 from the payload and show the message the way it wants. The message
2422 sent by server is implementation specific.
2424 * Changed public keys to comply with the protocol specification.
2425 Old public keys are not supported anymore and are not compatible.
2427 * Removed nickname from Channel Payload as the latest draft removed
2428 it. The client must resolve the nickname from the NAMES command
2429 reply received when it joined the channel.
2431 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2433 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Fixed some errors in protocol specification drafts.
2437 * Created lib/silccore/silcnotify.c to implement Notify Payload
2438 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2439 generic payloads described by protocol specifications. The file
2440 includes implementations for ID Payload and Argument Payload.
2442 * Changed Command Payload implementation to use the new Argument
2443 Payload. Changed command_xxxx_payload to command_payload_xxxx
2444 to comply with SILC coding conventions.
2446 * Added suppport for Argument Payload handling in Notify Payload
2447 implementation as protocol requires it. Added the new support
2448 into server and client lib as well.
2450 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Added support for multiple nicknames on same channel. [n] is
2453 added locally to the nickname if there are more than one same
2454 nicknames on the channel.
2456 * Server now sends all nicknames that matched WHOIS request.
2457 Client also shows the list received from server.
2459 * Added TOPIC command to client side. User can now set and show
2460 current topic on channel.
2462 * Added MOTD command to client and server. Also, server sends the
2463 motd when client connects to the server.
2465 * Changed version strings to comply ISO 8601.
2467 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Fixed protocol error handling in client library. It should now
2470 cope even if the SKE fails for some reason.
2472 * Made new protocol specification drafts for submitting to IETF.
2474 * Implemented TOPIC command to server in silcd/command.c.
2476 * Added two new notify types into lib/silccore/silcnotify.h:
2477 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2478 notify nickname change and topic setting/change on a channel.
2480 * API change of command_reply operation in client library. The
2481 application gets now the status type received from server as well.
2483 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2487 * Cras fixed and optimized the packet handling even further and
2488 it should work now. Minor change to the prototype of function
2489 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2491 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Added new function into lib/silcutil/silcschedule.[ch]:
2494 silc_schedule_with_fd to select() a specified fd. The function
2495 returns after timeout expires or data arrives or goes. The
2496 function is used by packet routines to wait that all data is
2497 received from network.
2499 * Fixed data reading from network in lib/silccore/silcpacket.c.
2500 The code now assures that all data is read from the fd and then
2501 continues packet processing. This was a bug fix since the code
2502 used to drop some data in some circumstances.
2504 * Added new function into lib/silcclient/client.[ch]:
2505 silc_client_start_key_exchange to start key exchange after
2506 connection has been established to server. The code internally
2507 now uses this funtion but its main purpose was to provide it
2508 for applications that perform their own connecting. After
2509 application has created a connection it merely calls this
2510 function to start the key exchange between client and server.
2511 The library takes care of everything else after that.
2513 Updated also lib/silcclient/README to explain the usage of
2516 * Do not send to application information that connection has
2517 been established. Application gets notified it by connect
2520 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Applied cras's patch to add silc_schedule_one function. The
2523 function runs scheduler once and returns.
2525 * Fixed the scheduler after cras messed it up. The timeout
2526 handling works now as it's supposed to work.
2528 * Added into lib/silccore/ silcnotify.h to include notify
2529 message types support. Changed silc_server_send_notify*
2530 functions, in server.[ch], to support those new notify types.
2531 Added the support for the notify types into client library,
2532 as well. Added new notify client operation into ops.h in
2535 * Changed silc_server_packet_send_to_channel to send normal
2536 packets instead of just channel message packets. The function
2537 is now used to send the notify packets to channels. It is not
2538 used to send channel message packets anymore, as server never
2541 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2542 va_arg()s as it seems to require it nowadays. I guess, if SILC
2543 is compiled with older va_arg() the new code should work anyway.
2545 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Splitted core library. Core library (lib/silccore) includes
2548 now only SILC protocol specific core (and common) components.
2549 Created new utility library (lib/silcutil) that includes more
2550 generic purpose stuff. The stuff for util library was taken
2551 from the old core library. This was minor and easy split.
2553 * Created SILC Client Library (lib/silcclient) that includes
2554 implementation of the SILC client without user interface. This
2555 was major move from silc/ directory. The code has been changed
2556 so that it is transparent towards the user interface. The
2557 silc/ directory includes now the same user interface as before
2558 and it uses the new client library. Read lib/silcclient/README.
2559 Basicly, the client library performs everything else related
2560 to SILC except user interface handling. Also, configuration
2561 files are considered to be part of user interface and library
2562 does not handle them.
2564 This change also changed a lot of structures, function naming etc.
2565 Most important change was that SilcClientWindow object was
2566 renamed to SilcClientConnection in the client library. Created
2567 also new file lib/silcclient/ops.h. Also added new files
2568 silc/local_command.[ch] and silc/client_ops.[ch].
2570 All these changes were made to make it easier for user interface
2571 designers to create what ever user interface for the SILC client
2574 It is also expected that the server will be moved to lib
2575 directory as well and SILC Server Library will be created;
2576 sometimes in the future.
2578 * Removed Local commands from lib/silccore/silccommand.h as
2579 they are application specific and new client library does not
2580 handle any of those anymore.
2582 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2583 old client implementation in silc/.
2585 * Added support for callback functions in SILC_LOG_* macros.
2586 Application can now set its own callbacks that will be called
2587 instead of using the default functions that will always print
2588 the debug messages to stderr (or stdout). Also, debugging can
2589 now be disabled by setting silc_debug to FALSE and re-enabled by
2590 setting it to TRUE. Note, that logging will still work even
2591 if debugging is disabled.
2593 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2594 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2595 silc_log_reset_debug_callbacks.
2597 * To enable debugging in silc client one must give now -d
2598 option on command line.
2600 * Changed silc_schedule_init to automatically allocate task queues
2601 if they are not allocated before calling it.
2603 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added GMP 3.1 into math library.
2607 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2610 a channel in SILC network. The packet is used by servers and
2611 routers to notify other routers that user has left a channel.
2612 This little feature was missing until now. Added the feature
2613 to protocol specification as well.
2615 Added functions: silc_server_send_remove_channel_user and
2616 silc_server_remove_channel_user into server.[ch].
2618 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2619 lib/silccore/silcpacket.h. However, they are not implemented
2622 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Fixed joining to a channel and sending channel messages
2625 between server and router. The channel message sending should
2626 now work inside a cell.
2628 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Fixed the private message sending between server and router.
2631 The private message sending should now work inside a cell.
2633 * Added silc_server_replace_id into server.[ch] to replace
2634 existing ID in the SILC network.
2636 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2637 and silc_idlist_replace_server_id into idlist.[ch] in server.
2639 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Fixed the server to server connections. Server can again now
2642 connect to router. Router to router connections probably does
2645 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Added dynamic protocol registering support. Now protocols can
2648 registered and unregistered on the fly. Patch by cras.
2650 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added lib/contrib directory to hold routines that some platforms
2653 don't have but are needed by SILC.
2655 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2656 into lin/contrib to provide getopt() and getopt_long() for
2657 those who don't have it.
2659 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added AWAY command to client. When away message is set and
2662 client receives a private message packet the client automatically
2663 replies to the sender with the away message.
2665 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2666 bug seemed to be the cause of recent problems when compiling
2669 * Added version detection support to SKE protocol specification
2670 and added the new changes to the SKE implementation as well.
2671 There were other minor changes in the SKE protocol as well.
2673 Many changes in lib/silcske/silcske.[ch] and in
2674 lib/silcske/payload.[ch].
2676 * Added ^U functionality, clear input line. Patch from cras.
2678 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Mainly small bugfixes on core library. Fixed some debugging
2681 logging and buffer overflow in silclog.c.
2683 * Updated config.sub and config.guess on the distribution tree.
2685 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Added command lagging support in server. Client may execute
2688 commands now only once in two seconds.
2690 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Optimized packet reception. MAC computation and checking is now
2693 also more optimized. A lot previously duplicated code is now
2694 used as generic by both client and server.
2696 * Fixed key pair generation in clientutil.c
2698 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Added into lib/silccore/silcbufutil.[ch] new function;
2701 silc_buffer_realloc.
2703 * Moved generic packet sending/encryption functions to
2704 lib/silccore/silcpacket.[ch] from client and server. Some
2705 rewriting of the functions.
2707 * Moved all generic packet reception/decryption functions to
2708 lib/silccore/silcpacket.[ch] from client and server. The
2709 packet processing is now much cleaner in both client and server.
2710 These were major changes in both client and server.
2712 * Created many common functions in server to do packet sending.
2713 Previously code were duplicated a lot, this has been removed
2716 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2718 * Rewrote major parts of the ID cache system. Don't know
2719 whether it is better now or not but at least the API is more
2722 * Major rewrite on ID cache stuff on client because of the ID
2723 cache API changes. Added idlist.c to client.
2725 * Also major rewrite on ID cache stuff on server as well.
2726 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2727 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2728 in hand, instead they are all put into the ID cache system now.
2729 All server_idlist_* routines uses ID cache now instead of
2730 traversing its own lists (those lists does not exist anymore).
2731 SilcIDList though still exists. Also, SilcXXXEntry's are
2734 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Finally made the SKE implementation compliant to the protocol
2737 specification. All mp integers are now binary encoded as
2738 opposed being HEX encoded.
2740 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2743 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2744 functions: silc_[encode/decode]_pem. Also added function
2745 silc_encode_pem_file to PEM encode with newlines ('\n') for
2748 * SILC public keys are now encoded either PEM or binary. Same
2749 option is for private keys as well. By default private keys
2750 are binary encoded and public keys PEM encoded. Silly HEX
2751 encoding were removed.
2753 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2754 function to create fingerprints.
2756 * Fixed a bug in SHA1; does not change the original data anymore.
2758 * Partly implemented INFO command on client and server side.
2759 Fixed CLEAR command. Changes to SERVER command; show current
2760 server(s) when giving command without arguments. Added
2761 VERSION command to client.
2763 * Added check to server that unregistered connections cannot
2764 execute commands (unless it is specificly allowed).
2766 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Fixed screen refresh.
2770 * Fixed channel joining bug from client. On some circumstances
2771 client tried to join to a channel it had already joined.
2773 * Added public key verification process into client's protocol.c.
2774 The client now verifies the public key from user and saves
2775 it into ~./silc/serverkeys/ directory.
2777 Added into: clientutil.[ch]: silc_client_verify_server_key.
2779 * Changed SKE protocol's silc_ske_initiator_finish function
2780 to accept callback function that verifies the received public
2781 key. Removed old silc_ske_verify_public_key function.
2783 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2786 silc_pkcs_private_key[_data]_set.
2788 * Made the password and public authentication more cleaner in
2789 server's protocol.c.
2791 * Removed historic and obsolete protocol `channel_auth' from
2792 both client and server.
2794 * Removed wrong way of sending command status messages from
2795 server to client in server's command.c. The old way violated
2796 protocol specification.
2798 Changes to silccore/silccommand.[ch]: removed
2799 silc_command_encode_status_payload -> not needed anymore,
2800 changed silc_command_encode_payload_va to accept extra
2801 argument on variable argument list. The argument type must
