3 * Redefined the Private Message Payload to support private message
4 keys and to support the new private message flags. Updated
7 * Added new type SilcPrivateMessagePayload and defined an API
8 for it in the lib/silcclient/silcprivate.[ch].
10 * Tested private message private keys successfully. Tested the
11 private message key set, unset and list commands with the new
14 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Added SilcKeyAgreementStatus type to the key agreement routines
17 to indicate the current status and error if one occured.
18 The status types are defined in the lib/silcclient/silcapi.h.
20 * Added new local command KEY that is used to set and unset private
21 keys for channels, set and unset private keys for private messages
22 with remote clients and to send key agreement requests and
23 negotiate the key agreement protocol with remote client. The
24 key agreement is supported only to negotiate private message keys,
25 it currently cannot be used to negotiate private keys for channels,
26 as it is not convenient for that purpose.
28 * Fixed a minor pending callback setting bug in the function
29 silc_client_get_client_by_id_resolve, now the function works.
30 Affected file lib/silcclient/idlist.c.
32 * Added function silc_net_get_local_port to get local bound
33 port by socket. Added to lib/silcutil/silcnet.[ch].
35 * Added `sockets' and `sockets_count' fields to the SilcClient
36 object. They hold the sockets of the listenning sockets in
37 the client. Listenning sockets may be for example the key
38 agreement server. Affected file lib/silcclient/client.[ch].
39 Added functions the silc_client_add_socket and the
40 silc_client_del_socket. They are exported to the application
43 * Added ~./silc/clientkeys to support other client's public keys.
45 * Renamed verify_server_key client operation to verify_public_key
46 and added one argument to indicate the type of the connection
47 (server, client etc.).
49 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Added silc_server_connection_auth_request to handle the
52 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
53 silcd/packet_receive.[ch].
55 * Added silc_server_send_connection_auth_request into the
56 silcd/packet_send.c to send the connection auth request packet.
58 * Cleaned up the silcd/protocol.c a bit and fixed some memory
61 * Fixed the public key authentication in responder side in the
62 server. The `auth_data' pointer includes the SilcPublicKey
63 not the path to the public key. Affected file silcd/protocol.c.
65 * Implemented the public key authentication in the initiator side
66 in the server. Affected file silcd/protocol.c.
68 * Removed the [RedirectClient] config section from the server
69 configuration. Is not needed and I don't want to implement it.
71 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Cleaned up the CMODE command in the server. It now works
74 correctly and supports all the modes defined in the protocol.
75 Affected file is silcd/command.c.
77 * Added `hmac_name' field to the SilcChannelEntry in the server
78 to hold the default HMAC of the channel. It can be set when
79 creating the channel (with JOIN command). Affected files
82 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
83 type to indicate the change of the current cipher and hmac
84 on the channel. Client can safely ignore the <cipher> argument
85 (if it chooses to do so) since the CHANNEL_KEY packet will
86 force the channel key change anyway. The <hmac> argument is
87 important since the client is responsible of setting the new
88 HMAC and the hmac key into use.
90 * Fixed the CMODE command in the client library as well.
92 * Tested CMODE command in router environment successfully.
94 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
96 * Show the version of the remote client (or server) when connecting
97 to the server. It is logged to the log file. Affected file
100 * Fixed the KILLED notify handling in the client library. The
101 client must be removed from all channels when receiving the
104 Also, do not remove the client entry when giving the KILL
105 command but when the KILLED notify is received.
107 * Removed silc_idlist_find_client_by_nickname from the server.
108 Not needed anymore. Affected files silcd/idlist.[ch].
110 * Implemented the CHANNEL_CHANGE notify type handling to the
111 server. Affected file silcd/server.c.
115 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Added silc_server_send_notify_invite to send the INVITE
118 notify between routers.
120 * Implemented the INVITE command correctly to the server.
122 * Implemented the INVITE notify type handling in the server.
124 * Implemented the INVITE command to the client library and on the
127 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Added function silc_server_get_client_resolve to find the
130 client entry by ID from all ID lists and then resolve it
131 (using WHOIS) if it cannot be found. Affected file is
134 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Implemented the BAN command to the client library.
138 * The JOIN command in the server now checks the invite list
141 * Changed the silc_command_reply_payload_encode_va and the
142 silc_command_payload_encode_va to support that if argument is
143 NULL it ignores and checks the next argument. Affected file
144 lib/silccore/silccommand.c.
146 * Added silc_server_send_notify_ban to send the BAN notify
147 type between routers.
149 * Chaned the silc_notify_payload_encode to support that if
150 argument is NULL it ignores and checks the next argument.
151 Affected file lib/silccore/silcnotify.c.
153 * Tested ban lists in router environment successfully.
155 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Implemented BAN command to the server, in silcd/command.[ch].
159 * Removed the BAN and INVITE_LIST modes from the CMODE command
162 * Added function silc_string_match to regex match two strings.
163 Affected files lib/silcutil/silcutil.[ch].
165 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Redefined parts of the SilcChannelEntry in the server to support
168 the new ban and invite lists.
170 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Redefined the INVITE command. The same command can be used to
173 invite individuals to the channel but also to manage the invite
174 list of the channel (to add to and remove from the invite list).
175 Updated the protocol specs.
177 * Added new command SILC_COMMAND_BAN that can be used to manage
178 the ban list of the channel. Updated the protocol specs.
180 * Removed the channel modes: the SILC_CMODE_BAN and the
181 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
182 in the CMODE command. The equivalent features are now available
183 using INVITE and BAN commands. Updated the protocol specs.
185 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
186 in the network about change in the current ban list. The notify
187 type is not used by the client.
189 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
190 support the invite lists.
192 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Added new function silc_string_regexify that converts string
195 including wildcard characters into regex string that can
196 be used by the GNU regex library. Added into the file
197 lib/silcutil/silcutil.[ch].
199 Added silc_string_regex_combine to combine to regex strings
200 into one so that they can be used as one regex string by
201 the GNU regex library. Added into the file
202 lib/silcutil/silcutil.[ch].
204 Added silc_string_regex_match to match two strings. It returns
205 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
207 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Imported GNU regex to the soruce tree into lib/contrib.
210 Fixed some compiler warning from the regex.c.
212 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Fixed MOTD command in the server to work in router environment.
216 * Fixed the MOTD command in the client library to support
217 the server argument in the command.
219 * Added `nickname_len' argument to the silc_idlist_add_client
220 in the server, as the `nickname' argument may be binary data
223 * Added silc_idlist_get_channels to return all channels from
226 * Implemented LIST command to the server. Affected file is
229 * Implemented the LIST command to the client library and on the
232 * Added [<user count>] argument to the LIST command reply.
233 With private channels the user count is not shown.
235 * Updated TODO and README.
237 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * The client entry's data.registered must be TRUE even with
240 global client entry on global client list. The data.registered
241 is used to check whether the client is anymore in the network,
242 for example with WHOWAS command so it must be valid.
244 * Fixed the WHOWAS command in the server. It now actually works
245 in router environment. Added function into silcd/command_reply.c
246 silc_server_command_reply_whowas_save.
248 * Added silc_idlist_purge function to the silcd/idlist.c
249 to periodically purge the ID Cache.
251 * Fixed INFO command in the server. It works now in router
252 environment. Added <server name> argument to the INFO command
253 reply. Updated the protocol specs.
255 * Fixed minor bug in silc_idcache_purge to not purge if the
256 expire value is zero.
258 * Fixed various bugs in WHOIS and IDENTIFY command handling as
259 they were buggy because of the WHOWAS information.
261 * Fixed local command MSG to handle the async resolving of
262 the remote client properly. It used to fail the first MSG.
263 Affected file silc/local_command.c.
265 * Added `data_len' field to SilcIDCache context.
267 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Update TODO. Todo in commands in the server.
271 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
274 used by routers as broadcast packet to inform other routers
275 about the changed user mode.
277 Implemented the notify handling in the server. Affected file is
278 silcd/packet_receive.c. Added the function
279 silc_server_send_notify_umode to the silcd/packet_send.[ch].
281 * Added new generic Channel Payload and deprecated the New Channel
282 Payload. The New Channel Payload is now the generic Channel
285 * Added new argument `mode' to the silc_server_send_new_channel
286 as it is required in the Channel Payload now.
288 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
289 and created a new and real SilChannelPayload to represent the
290 new generic Channel Payload. Implemented the encode/decode
291 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
293 * Added silc_server_get_client_channel_list to return the list
294 of channels the client has joined for WHOIS command reply.
295 Affected file silcd/server.[ch].
297 * Implemented the channel list sending in the WHOIS command reply
298 in server and in the client.
300 Implemented the channel list displaying on the user interface
301 as well. Affected file silc/client_ops.c.
303 * Added silc_channel_payload_parse_list to parse list of Channel
304 Payloads. It returns SilcDList list of SilcChannelPayloads.
305 Client for example can use this function to parse the list of
306 channels it receives in the WHOIS command reply. The caller
307 must free the list by calling silc_channel_payload_list_free.
308 Affected files lib/silccore/silcchannel.[ch].
310 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Added one new argument <user mode> to the WHOIS command reply
313 to return the mode of the user in SILC. Updated the protocol
316 Implemented it to the server and client.
318 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Fixed the mode printing on the user interface on joining.
321 Affected file silc/client_ops.c.
323 * Implemented the UMODE command and user modes in general to the
324 client library and to the user interface.
326 * Implemented the UMODE command to the server.
328 * The server now sends UNKNOWN_COMMAND error status if client sends
329 unknown command. Affected file silcd/command.c.
331 * All server commands now handle the command identifier the right
332 way when sending the command reply to the client. The client can
333 use to identify the command replies with the identifier.
335 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Added silc_server_get_client_route to resolve the route to
338 the client indicated by the client ID. Affected file is
341 * Added silc_server_relay_packet as general function to relay
342 packet to arbitrary destination. This deprecates functions
343 like _send_private_message_key, _relay_notify etc. Affected
344 file is silcd/packet_send.[ch].
346 Removed silc_server_send_key_agreement,
347 silc_server_send_private_message_key and
348 silc_server_packet_relay_notify functions from the file
349 silcd/packet_send.[ch].
353 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
354 server. Affected file silcd/packet_receive.[ch].
356 * Implemented the KILL command to the client. Implemented the
357 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
358 Affected files lib/silcclient/command[_reply].c and
359 lib/silcclient/client_notify.c. Implemented the KILL notify
360 printing in the user inteface.
362 * Fixed a lot silc_parse_nick memory leaks from the client
363 library in the file lib/silcclient/command.c.
365 * Changed the silc_server_send_notify_on_channels's `sender'
366 argument from SilcSocketConnection to SilcClientEntry to
367 check the sender as entry and not as connection object and not
368 to send to the client provided as argument. The affected file
369 is silcd/packet_send.[ch].
371 * The notify packets that are destined directly to the client used
372 to not to be processed by the server. Now changed that and the
373 server processes all notify packets. After relaying the packet
374 to the client the notify packet is processed in the server.
376 * The silc_server_free_client_data now checks whether there is
377 pending outgoing traffic for the client and purges the data to
378 the network before removing the client entry.
380 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
383 an client is killed from the SILC Network. Updated the protocol
386 Added new function silc_server_send_notify_killed to the
387 silcd/packet_send.[ch].
389 * Added function silc_server_packet_relay_notify to relay notify
390 packets that are destined directly to a client. In this case
391 the server does not process the notify packets but merely relays
392 it to the client. Affected file silcd/packet_send.[ch].
394 Added also silc_server_packet_process_relay_notify to check
395 whereto relay the notify. Affected file is
396 silcd/packet_receive.[ch].
398 * Implemented the KILL command to the server.
402 * Added the backup schema desgined last fall to the protocol
403 specs for everyone to see. The specification is in the
404 *-spec-xx.txt draft and the packet type definitions for the
405 backup routers is in *-pp-xx.txt draft. Thusly, added also
406 new packet type SILC_PACKET_CELL_ROUTERS.
408 * A big security problem in the implementation discovered. The
409 signoff of an client did not cause new channel key generation
410 which it of course should've done. The channel keys must be
411 always re-generated when client leaves (or signoffs) the channel.
412 The silc_server_remove_from_channels funtion now handles
413 the channel key re-generation.
415 * Added `sender' argument to the silc_server_send_notify_on_channels
416 to not to send the client provided as argument. Affected file
417 silcd/packet_send.[ch].
419 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
421 * Implemented OPER and SILCOPER commands into the server and
424 * Added silc_auth_verify and silc_auth_verify_data to verify
425 the authentication directly from the authentication payload.
426 It supports verifying both passphrase and public key based
427 authentication. Affected file lib/silccore/silcauth.[ch].
429 * Added `hash' field to the SilcIDListData structure. It is the
430 hash negotiated in the SKE protocol. Affected file is
433 * Slight redesigning of the SilcAuthPayload handling routines.
434 Do not send SilcPKCS but SilcPublicKey as argument.
436 * Implemented the public key authentication support to the
437 serverconfig. The public key is loaded from the provided path
438 and saved as authentication data to void * pointer. Thus,
439 changed the unsigned char *auth_data to void *auth_data;
441 * Fixed SHUTDOWN command to send the reply before the server
442 is shutdown. :) Affected file silcd/command.c.
444 * Fixed fatal bug in CONNECT command. The hostname was invalid
445 memory and server crashed. Affected file silcd/command.c.
447 * Fixed fatal bug in CLOSE command. The server_entry became
448 invalid but was referenced later in the command. Affected file
451 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Fixed fatal bug in failure packet handling. Server ignored
454 the failure and thus crashed when it came.
458 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
460 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
461 that the command may be executed only once in (about) 2 seconds.
462 The old SILC_CF_LAG flag is same but allows command bursts up
463 to five before limiting.
465 Added the support for CF_LAG and CF_LAG_STRICT flags to the
466 server code. Various commands now includes the CF_LAG_STRICT
467 flag to disallow any kind of miss-use of the command.
469 * Fixed the silc_buffer_unformat to not to allocate any data
470 if the length of the data is zero. It used to allocate the
471 length + 1. Affected file lib/silcutil/silcbuffmt.c.
473 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Changed the format of AdminConnection configuration section
476 in the server. Added username of the admin to the format.
477 Affected files silcd/serverconfig.[ch].
479 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
480 to return admin configuration data by host, username and/or
483 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
485 * Implemented WHOWAS command to the server. Added the functions:
487 silc_server_command_whowas_parse,
488 silc_server_command_whowas_send_reply,
489 silc_server_command_whowas_from_client and
490 silc_server_command_whowas_from_server
492 * Added <Client ID> argument to the WHOWAS command reply. Updated
493 the protocol specs accordingly.
495 * Implemented WHOWAS command and command_reply to the client
498 Implemented the WHOWAS printing on the user interface.
500 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Added new argument to the WHOWAS command reply, the real name.
503 It is an optional argument. Updated the protocol specs.
505 * Added SilcIDCacheDestructor callback that is registered when
506 the SilcIDCache is allocated. The callback is called when
507 an cache entry in the ID Cache expires, or is purged from the
508 cache. Added into lib/silccore/idcache.[ch].
510 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
511 to destruct the client entries when the cache entry expires.
512 Other ID Cache's in server and in the client library ignores
515 * If the ID Cache entry's `expire' field is zero then the entry
516 never expires. Added boolean `expire' argument to the
517 silc_idcache_add function in the lib/silccore/idcache.[ch].
518 If it is TRUE the default expiry value is used.
520 * Added silc_server_free_client_data_timeout that is registered
521 when client disconnects. By default for 5 minutes we preserve
522 the client entry for history - for WHOWAS command.
524 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Added support to the server to enforce that commands are not
527 executed more than once in 2 seconds. If server receives
528 commands from client more frequently, timeout is registered
529 to process the commands. Affected file silcd/command.c.
530 Added new function silc_server_command_process_timeout.
532 * Changed NICK_NOTIFY handling in client library to check that
533 if the client's nickname was changed, so there is no need to
534 resolve anything from the server.
536 * Removed error printing from the WHOIS and IDENTIFY commands.
537 If error occurs then it is ignored silently in the client library.
538 The application, however, may map the received error to
539 human readable error string. The application currently maps
540 the NO_SUCH_NICKNAME error to string.
542 * Made the command status message public to the application. Moved
543 them from lib/silcclient/command_reply.c to
544 lib/silcclient/command_reply.h. The application can map the
545 received command status to the string with the
546 silc_client_command_status_message function.
548 * Added check to the server to check that client's ID is same
549 as the Source ID in the packet the client sent. They must
552 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Added dist-bzip hook to the Makefile.am to make bzip2
555 compressed distributions.
557 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Server now enforces the maximum length for the nickname and
560 the channel as protocol specification dictates. 128 bytes for
561 nickname and 256 bytes for channel name.
563 * Moved the WHOIS printing to the application. The client libary
564 does not print out the WHOIS information anymore, the application
565 must do it. Renamed silc_client_command_reply_whois_print to
566 the silc_client_command_reply_whois_save.
568 The client's idle time is also sent to the application now, and
569 the idle is shown on screen.
571 * Added silc_client_command_reply_identify_save to save the
572 received IDENTIFY entries.
574 * Do not check for channel private keys in message sending and
575 reception if the channel does not have the PRIVKEY mode set.
576 Affected file lib/silclient/client_channel.c.
578 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
580 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
581 just surfaced after chaning the JOIN procedure.
583 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
585 * Added silc_client_get_clients_by_list to get client entries
586 from Client ID list, that is returned for example by JOIN
587 and USERS command replies. The application should use this
588 function for example when JOIN command reply is received to
589 resolve the clients already on the channel (library does not
590 do that anymore as USERS command reply is not used in the JOIN
591 procedure anymore). Affected files lib/silcclient/silcapi.h and
592 lib/silcclient/idlist.c.
594 * JOIN command reply and USERS command reply returns now SilcBuffer
595 pointers instead of unsigned char pointers when returning
596 the client list and mode list.
598 * Added <Client ID> argument to the JOIN command reply, mainly
599 for the server to identify for which client the command was
600 originally sent. Updated protocol specs accordingly.
602 * Added SilcDlist private_key pointer to the SilcChannelEntry
603 in the client to support the channel private keys. Affected
604 file is lib/silcclient/idlist.h.
606 * Added SilcChannelPrivateKey argument to the function
607 silc_client_send_channel_message so that application can choose
608 to use specific private ke if it wants to. If it is not provided,
609 the normal channel key is used, unless private keys are set.
610 In this case the first (key that was added first) is used
611 as the encryption key.
613 * Implemented the support for channel private key handling.
614 Implemented the following functions:
616 silc_client_add_channel_private_key,
617 silc_client_del_channel_private_keys,
618 silc_client_del_channel_private_key,
619 silc_client_list_channel_private_keys and
620 silc_client_free_channel_private_keys
622 Affected file lib/silcclient/client_channel.c.
624 * Added the support for the private keys in the channel message
625 sending and encryption and in the message reception and
626 decryption. Affected funtions are
627 silc_client_send_channel_message and silc_client_channel_message.
629 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added SKE's key verify callback to the client library's
632 KE protocol context. Affected files lib/silcclient/protocol.[ch].
634 * Removed the statement that server (or router) must send USERS
635 command reply when joining to the channel so that the client
636 knows who are on the channel. Instead, the client list and
637 client's mode list is now sent in the JOIN command reply to the
638 client who joined channel. This is better solution.
640 * Added function silc_server_get_users_on_channel and function
641 silc_server_save_users_on_channel to the silcd/server.[ch].
643 * Removed function silc_server_command_send_users from the
646 * Do not show topic on the client library anymore. The topic is
647 sent in the command reply notify to the application and the
648 application must show the topic now.
650 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Added client searching by nickname hash into the IDENTIFY and
653 WHOIS commands in the server as they were clearly missing from
654 them. Affected file is silcd/command.c.
656 * Fixed a bug in private message receiving in the client library.
657 The remote ID was freed and it wasn't supposed, now it is
660 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Minor fix to the channel payload; allocate the data area, as it
663 needs to be of specific length.
665 * If the key agreement port is zero then the operating
666 system will define the bound port. Affected files are
667 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
669 * Added new function silc_channel_payload_decrypt into the file
670 lib/silccore/silcchannel.[ch].
672 * Moved the channel message etc, check from silc_packet_decrypt
673 to applications. The library calls now a generic
674 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
675 when the packet is either normal or special. This was done to
676 allow more wide range of checking that was not allowed when
677 the code was in library. Now applications can do virtually any
678 checks to the packet and return to the library the decision how
679 the packet should be processed. Affected files are
680 lib/silccore/silcpacket.[ch].
682 Added silc_server_packet_decrypt_check to the server and
683 silc_client_packet_decrypt_check to the client library.
685 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
686 to send with specified source and destination information.
688 * Channel message delivery between routers was broken after the
689 channel key distribution was fixed earlier. The channel key
690 was used be to distributed to other routers as well which is not
691 allowed by the protocol. Now this is fixed and channel keys
692 really are cell specific and the channel message delivery between
693 routers comply with the protocol specification.
695 * Fixed various commands in server to check also the global list
696 for the channel entry and not just the local list. The affected
697 file silcd/command.c.
699 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added assert()s to buffer formatting and unformatting routines
702 to assert (if --enable-debug) when error occurs. Affected
703 file: lib/silcutil/silcbuffmt.c.
705 * Changed to auto-reconnect to check whether the remote host is
706 router and register the re-connect timeout if it is. It used
707 to check that whether we are normal server, but router must do
708 auto-reconnect with another router as well. Affected file
711 * Removed the [<key len>] option from CMODE command as the cipher
712 name decides the key length, nowadays. See the defined ciphers
713 from the protocol specification.
715 * Added [<hmac>] option to the CMODE command to define the HMAC
716 for the channel. Added SILC_CMODE_HMAC channel mode.
718 * Added [<hmac>] option for the JOIN command so that user can
719 select which HMAC is used to compute the MACs of the channel
722 * Added Hmac field to the Channel Message Payload. The integrity
723 of plaintext channel messages are now protected by computing
724 MAC of the message and attaching the MAC to the payload. The
725 MAC is encrypted. Now, it is clear that this causes some
726 overhead to the size of the packet but rationale for this is that
727 now the receiver can verify whether the channel message decrypted
728 correctly and also when private keys are set for the channel the
729 receiver can decrypt the packet with several keys and check from
730 the MAC which key decrypted the message correctly.
732 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
733 lib/silccrypt/silccipher.[ch].
735 * Added silc_hash_len to return the digest length into the
736 lib/silcrypt/silchash.[ch].
738 * Rewrote parts of Silc Channel Payload interface in the
739 lib/silccore/silcchannel.[ch]. The encode function now also
740 encrypts the packet and parse function decrypts it.
742 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Fixed a minor formatting bug in the SKE's key material processing.
745 It actually might have processed the keys wrong way resulting
748 * Redefined the mandatory HMAC algorithms and added new algorithms.
749 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
750 and hmac-md5 truncated to 96 bits. The mandatory is now
751 hmac-sha1-96. Rest are optional (including the one that used
752 to be mandatory). Rationale for this is that the truncated HMAC
753 length is sufficient from security point of view and can actually
754 make the attack against the HMAC harder. Also, the truncated
755 HMAC causes less overhead to the packets. See the RFC2104 for
758 * Added new [hmac] configuration section. The SKE used to use
759 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
760 is of course wrong. The official names that must be proposed in
761 the SKE are the ones defined in the protocol specification
762 (hmac-sha1-96 for example). The user can configure any hmac
763 using any hash function configured in the [hash] section. At
764 least, the mandatory must be configured.
766 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
768 * Added HMAC list to the SKE proposal list. It has now both
769 hash algorithm list and HMAC list. This makes the protocol
770 incompatible with previous versions. The SKE now seems to work
771 the way it is supposed to work, for the first time actually.
773 * Defined plain Hash algorithms to the protocol specification.
776 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Implemented support for key agreement packets into the server.
779 Added functions silc_server_key_agreement and
780 silc_server_send_key_agreement. Other than these functions,
781 server has nothing to do with this packet.
783 * Added support for private message key packets into the server.
784 Added functions silc_server_private_message_key and
785 silc_server_send_private_message_key.
789 * Changed the silc_[client|server]_protocol_ke_set_keys to be
790 called in the protocol's final callback instead in the END
791 protocol state. This makes a little more sense and in the same
792 time in client we can use the same protocol routines for normal
793 key exchange and to key agreement packet handling as well.
795 * Added to both client's and server's KE protocol context the
796 SilcSKEKeyMaterial pointer to save the key material. We will
797 bring the key material to the protocol's final callback by doing
798 this. The final callback must free the key material.
800 * Added SKE's packet_send callback into client's KE protocol
801 context so that the caller can choose what packet sending function
802 is used. This way we can use different packet sending when
803 doing normal SKE when doing key agreement packet handling (in
804 the key agreement packet handling we do not want to encrypt
807 * Implemented the responder side of the key agreement routines
808 in the client. The client can now bind to specified port and
809 accept incoming key negotiation. The key material is passed
810 to the application after the protocol is over.
812 * Implemented the processing of incoming Key Agreement packet
813 in the client. Added function silc_client_key_agreement to
816 * Implemented the intiator side of the key agreement routines
817 in the client. The client can now initiate key agreement with
818 another remote client. The key material is passed to the
819 application after the protocol is over.
821 * Created client_keyagr.c to include all the key agreement
824 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
825 SILC_TASK_CALLBACK except that it is not static.
827 * Created client_notify.c and moved the Notify packet handling
828 from the client.[ch] into that file.
830 * Created client_prvmsg.c and moved all private message and
831 private message key routines from the client.[ch] into that file.
833 * Create client_channel.c and moved all channel message and
834 channel private key routines from the client.[ch] into that file.
836 * Changed silc_client_get_client_by_id_resolve to resolve with
837 WHOIS command instead of IDENTIFY command, in the file
838 lib/silclient/idlist.c.
840 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * Implemented the SKE's responder side to the Client library.
844 * When FAILURE is received to the protocol do not trust it
845 blindly. Register a timeout to wait whether the remote closes
846 the connection as it should do it, only after that process the
847 actual failure. This was changed to both client and server.
849 * Added client_internal.h to include some of the structures
850 there instead of client.h in lib/silcclient/.
852 * Added function silc_task_unregister_by_callback to unregister
853 timeouts by the callback function.
855 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Some "Incomplete WHOIS info" errors has been appearing on the
858 log files. Took away the entry->userinfo check from WHOIS
859 reply sending. The entry->userinfo is now " " if client did not
860 provide one. I thought this was fixed earlier but something
861 is wrong still. Let's see if the error still appears.
863 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Fixed a minor bug in the login when the channel key is
866 re-generated in the server. It used to generate the key in
867 wrong order and thus caused problems in the channel traffic.
869 * Fixed a minor bug in channel key distsribution after
870 KICK command. The key was not sent to the router even though
873 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Added silc_ske_process_key_material_data as generic routine
876 to process any key material as the SILC protocol dictates. The
877 function is used by the actual SKE library but can be used by
878 applications as well. This relates to the private message keys
879 and the channel private keys since they must be processed the
880 same way the normal SILC session keys. The protocol dictates
881 this. Affected files: lib/silcske/silcske.[ch].
883 Added also silc_ske_free_key_material to free the
884 SilcSKEKeyMaterial structure.
886 * Defined silc_cipher_set_key function to set the key for
887 cipher without using the object's method function. The affected
888 files: lib/silccrypt/silccipher.[ch].
890 * Implemented silc silc_client_add_private_message_key,
891 silc_client_add_private_message_key_ske,
892 silc_client_del_private_message_key,
893 silc_client_list_private_message_keys and
894 silc_client_free_private_message_keys functions in the
897 Added functions silc_client_send_private_message_key to send
898 the Private Message Key payload and silc_client_private_message_key
899 to handle incoming Private Message Key payload.
901 * Added Cipher field to the Private Message Key payload to set
902 the cipher to be used. If ignored, the default cipher defined
903 in the SILC protocol (aes-256-cbc) is used.
905 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Removed lib/silcclient/ops.h file.
909 Redefined parts of the SILC Client Library API. Created new
910 file silcapi.h that deprecates the ops.h file and defines the
911 published Client Library API. Defined also private message key
912 API and channel private key API into the file.
914 This is the file that the application must include from the
915 SILC Client Library. Other files need not be included by
916 the application anymore.
918 * Added new key_agreement client operation callback and also
919 defined the Key Agreement library API for the application.
921 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
924 is used by clients to request key negotiation between another
925 client in the SILC network. If the negotiation is started it
926 is performed using the SKE protocol. The result of the
927 negotiation, the secret key material, can be used for example
928 as private message key.
930 Implemented the Key Agreement payload into the files
931 lib/silccore/silauth.[ch].
933 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Redefined ciphers for the SILC protocol. Added some new ciphers
936 and defined the key lengths for the algorithms. Changed the
937 code accordingly. The default key length is now 256 bits.
939 * Fixed SKE key distribution function silc_ske_process_key_material
940 when the key length is more than 128 bits. The default key
941 length in SILC is now 256 bits.
943 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
944 to indicate unsupported algorithm.
946 * Renamed rijndael.c to aes.c and all functions as well.
948 * Fixed a long standing channel key setting bug in client library.
949 Weird that it has never surfaced before.
951 * Fixed bug in channel deletion. If the entire channel is removed
952 then it must also delete the references of the channel entry
953 from the client's channel list as the client's channel entry and
954 the channel's client entry share same memory.
956 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Implemented CONNECT and SHUTDOWN commands in the client.
960 * Implemented CLOSE command to the client.
962 * Added the function silc_idlist_find_server_by_name into the
963 files silcd/idlist.[ch].
965 Added the function silc_idlist_find_server_by_conn into the
966 files silcd/idlist.[ch].
968 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * DIE command was renamed to SHUTDOWN. Updated the both code
973 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
974 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
976 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
979 * Added function silc_server_create_connection function to create
980 connection to remote router. My server implementation actually
981 does not allow router to connect to normal server (it expects
982 that normal server always initiates the connection to the router)
983 so the CONNECT command is only good for connecting to another
986 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
989 or some other client was kicked from the channel.
991 Implemented the handling of the notify type to both client
994 Implemented silc_server_send_notify_kicked to send the KICKED
995 notify. It is used to send it to the server's primary router.
997 * Implemented the KICK command into server and client.
999 * Added `query' argument to the silc_idlist_get_client function
1000 to indicate whether to query the client from server or not if
1003 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1004 to indicate that the client is not channel founder.
1008 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Removed the rng context from SilcPacketContext structure and
1011 changed that the packet routine uses the Global RNG API.
1013 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Added support for quit message that client can "leave" on the
1016 channel when it quits the SILC. It is ditributed inside the
1017 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1019 Added silc_server_free_client_data that will take the
1020 signoff message as argument.
1022 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1024 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Updated parts of the protocol specification to keep it up
1029 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1032 payloads in one packet.
1034 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1035 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1036 use now the new List flag.
1038 * Also deprecated the following packet types: REPLACE_ID,
1039 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1041 * Added list support for Notify packet in server.
1043 * Added silc_server_send_notify_channel_change to send the
1044 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1045 the silc_server_send_replace_id.
1047 * Added silc_server_send_notify_nick_change to send the
1048 NICK_CHANGE notify type. Deprecates the function
1049 silc_server_send_replace_id.
1051 * Added silc_server_send_notify_join to send the JOIN notify type.
1052 Deprecates the function silc_server_send_new_channel_user.
1054 * Added silc_server_send_notify_leave to send LEAVE notify type.
1055 Deprecates the function silc_server_send_remove_channel_user.
1057 * Added silc_server_send_notify_cmode and
1058 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1059 types. Deprecates the silc_server_send_set_mode function.
1061 * Added SERVER_SIGNOFF notify type to indicate that server has
1062 quit. This means that all clients on the channel from that
1063 server will drop. This can be also used when netsplit happens.
1065 Deprecated REMOVE_ID packet type since it is not needed anymore
1068 Added silc_server_send_notify_server_signoff to send the
1069 SERVER_SIGNOFF notify type. Deprecates the function
1070 silc_server_send_remove_id.
1072 Added also silc_server_send_notify_signoff to send the
1073 SIGNOFF notify type.
1075 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1076 SILC protocol from this day on. Changed the protocol
1077 specification as well.
1079 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1080 notify type. It is used between routers to notify about
1081 topic changes on a channel.
1083 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1086 * Partly updated the protocol specification to comply with the
1087 changes now made. It is still though a bit outdated.
1089 * The JOIN notify type now takes one extra argument <Channel ID>.
1090 The packet used to be destined to the channel but now the
1091 JOIN type may be sent as list thus it is impossible to
1092 destine it to any specific channel. By adding this argument
1093 it is again possible.
1095 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Added CREDITS file. The CHANGES and CREDITS file will appear
1098 in the distribution as well.
1100 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1102 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1103 types in the server's silcd/packet_receive.c.
1105 * Implemented CMODE and CUMODE to work in router environment.
1107 * Fixed minor encoding and decoding buglet from the
1108 lib/silccore/silcmode.c.
1110 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1113 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1115 * Changed all SilcConfigServer* and silc_config_server* to
1116 SilcServerConfig* and silc_server_config*, respectively.
1119 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Associated the ID (client or server ID) to the Authentication
1122 Payload to avoid any possibility of forging. Updated the
1123 protocol specification and the code accordingly.
1125 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * The RSA key length is now save to the RsaKey context in the
1128 key generation process in lib/silccrypt/rsa.c. The key length
1129 is now used to figure out the maximum size of the block allowed
1130 to be encrypted/signed.
1132 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1133 is equivalent to the silc_mp_mp2bin but does not allocate any
1136 * Changed silc_mp_mp2bin API to take length argument. If it is
1137 non-zero then the buffer is allocated that large. If zero, then
1138 the size is approximated using silc_mp_sizeinbase, which however
1141 * Created Global RNG API which is global RNG that application can
1142 initialize. After initializing, any routine anywhere in the
1143 code (including library) can use RNG without allocating a new
1144 RNG object. This was done to allow this sort of use of the
1145 RNG in code that has no chance to allocate RNG object. All
1146 applications currently allocate this and many routines in the
1147 library use this. Affected file lib/silccrypt/silcrng.[ch].
1149 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1150 it to use the Global RNG API.
1152 * Defined Authentication Payload into protocol specification that
1153 is used during SILC session to authenticate entities. It is
1154 used for example by client to authenticate itself to the server
1155 to obtain server operator privileges.
1157 Implemented this payload into the lib/silccore/silcauth.[ch].
1158 Implemented also routines for public key based authentication
1159 as the new protocol specification dictates.
1161 Moved definitions of different authentication methods from
1162 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1164 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1165 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1166 silc_pkcs_verify_with_hash functions into the file
1167 lib/silccrypt/silcpkcs.[ch].
1169 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * The client entry's userinfo pointer must be always valid.
1172 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1173 will fail since it requires the userinfo. Now, the userinfo
1174 is allocated as "" if actual userinfo does not exist. Actually,
1175 it must exist and it is totally Ok to drop client connections
1176 that does not announce the userinfo. However, we will make
1177 this workaround for now.
1179 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1180 to return the remote port by socket.
1182 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1185 SILC_SERVER_PENDING_EXEC and added an new macro
1186 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1187 data or when error occurs while processing the pending command.
1189 Added new argument `destructor' into silc_server_command_pending
1190 and to the SilcServerCommandPending object. This destructor is
1191 now called after calling the pending callback or if error occurs
1192 immediately. If error occurs the actual pending callback won't
1193 be called at all - only the destructor. The destructor may be
1194 NULL if destructor is not needed.
1196 All this applies for client library code as well. Similar
1197 changes were made there as well for the pending commands.
1199 In the client, the application must now allocate the
1200 SilcClientCommandContext with the silc_client_command_alloc
1203 * Added reference counter to the SilcServerCommandContext. Added
1204 function silc_server_command_alloc and silc_server_command_dup
1207 Same type of functions added to the client library for the same
1210 * Removed the cmd_ident from IDListData away since it is now
1211 global for all connections. It is the command identifier used
1212 in command sending and with pending commands. The affected file
1215 * Added reference counter to the SilcSocketConnection objecet to
1216 indicate the usage count of the object. The object won't be
1217 freed untill the reference counter hits zero. Currently only
1218 server uses this, and client ignores it. The client must be
1219 set to use this too later. The affected files are
1220 lib/silccore/silcsockconn.[ch]. Added also the function
1221 silc_socket_dup to increase the reference counter.
1223 This was mainly added because it is possible that the socket
1224 is removed underneath of pending command or other async
1225 operation. Now it won't be free'd and proper DISCONNECTING
1226 flags, etc. can be set to avoid sending data to connection that
1227 is not valid anymore.
1229 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1230 the connection. After that it sets SILC_SET_DISCONNECTED.
1231 It is, however, possible that the socket data is not still freed.
1232 The silc_server_packet_process now checks that data is not
1233 read or written to connection that is DISCONNECTED. The socket
1234 get's freed when the reference counter hits zero.
1236 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Changed the client operation API: channel_message operation's
1239 `sender' is now the client entry of the sender, not the nickname
1240 and the `channel' is the channel entry, not the channel name.
1242 In the private_message operation the `sender' is now also the
1243 client entry of the sender not the nickname.
1245 Affected file is lib/silcclient/ops.h and all applications
1246 using the client operations.
1248 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Moved the calling of ops->connect() from connect_to_server_final
1251 into receive_new_id functin since that is the point when the
1252 client is actually allowed to send traffic to network. The
1253 affected file is lib/silcclient/client.c.
1255 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1258 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1259 (if needs broadcasting) instead of broadcasting the packets one
1260 by one which would make a burst in the network traffic.
1262 * Added `broadcast' argument to the functions in silcd/server.[ch]
1263 silc_server_create_new_channel[_with_id] to indicate whether
1264 to send New Channel packet to primary router.
1266 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Added new function into the silcd/server.[ch] files:
1269 silc_server_create_new_channel_with_id to create new channel with
1270 already existing Channel ID.
1272 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1273 lib/silccore/silcpacket.h. This packet is used t send list of
1274 Set Mode payloads inside one packet. Server uses this to set
1275 the modes for the channels and clients on those channels, that it
1276 announced to the router when it connected to it. The protocol
1277 specification has been updated accordingly.
1279 * The silc_server_new_channel did not handle the packet coming
1280 from normal server as it normally does not send that. However,
1281 when it announces its channels it does send it. Implemented
1282 the support for that.
1284 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1285 into the file lib/silccore/id.h.
1287 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Fixed memory leaks in the functions silc_idlist_del_client,
1290 silc_idlist_del_channel and silc_idlist_del_server in the file
1291 silcd/idlist.c. All of those leaked like a sieve.
1293 * Fixed some small memory leaks in the client's function
1294 silc_client_notify_by_server.
1296 * Added functions into silcd/server.c: silc_server_announce_clients,
1297 silc_server_announce_channels and silc_server_announce_server.
1298 These functions are used by normal and router server to announce
1299 to its primary router about clients, channels and servers (when
1300 router) that we own. This is done after we've connected to the
1303 These functions effectively implements the following packet types:
1304 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1305 and SILC_PACKET_NEW_ID_LIST.
1307 * Added new functions into the silcd/packet_receive.[ch]:
1308 silc_server_new_id_list, silc_server_new_channel_list and
1309 silc_server_new_channel_user_list to handle the incoming
1310 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1312 * Added support of changing Channel ID in the function
1313 silc_server_replace_id. If the server that announces a channel
1314 to the router already exists in the router (with same name but
1315 with different Channel ID), router is responsible to send
1316 Replace ID packet to the server and force the server to change
1317 the Channel ID to the one router has.
1319 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1320 client that the Channel ID has been changed by the router. The
1321 normal server sends this to the client. Client must start using
1322 the new Channel ID as the channel's ID.
1324 Implemented handling of this new type into lib/silcclient/client.c
1325 into the function silc_client_notify_by_server.
1327 * Added new function silc_idlist_replace_channel_id into the files
1328 silcd/idlist.[ch] to replace the Channel ID.
1330 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Call silc_server_command_identify_check always when processing
1333 the IDENTIFY command in silcd/command.c
1335 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1338 send keepalive packets. The packet can be sent by clients,
1339 servers and routers.
1341 Added function silc_socket_set_heartbeat into the file
1342 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1343 If not set, the heartbeat is not performed. The actual
1344 heartbeat is implemented in the low level socket connection
1345 library. However, application is responsible of actually
1348 Added silc_server_send_heartbeat to send the actual heartbeat
1349 packet into silcd/packet_send.[ch]. Server now performs
1350 keepalive with all connections.
1352 * Added silc_task_get_first function into lib/silcutil/silctask.c
1353 to return the timeout task with shortest timeout. There was a bug
1354 in task unregistration that caused problems. TODO has been
1355 updated to include that task system must be rewritten.
1357 * The client library will now resolve the client information when
1358 receiving JOIN notify from server for client that we know but
1359 have incomplete information.
1361 * Rewrote parts of silc_server_remove_from_channels and
1362 silc_server_remove_from_one_channel as they did not remove the
1363 channel in some circumstances even though they should've.
1365 * Encryption problem encountered in server:
1367 The LEAVE command used to send the Channel Key packet to the
1368 router immediately after generating it. However, the code
1369 had earlier sent Remove Channel user packet but not immediately,
1370 ie. it was put to queue. The order of packets in the router
1371 was that Channel Key packet was first and Remove Channel User
1372 packet was second, even though they were encrypted in the
1373 reverse order. For this reason, MAC check failed. Now, this
1374 is fixed by not sending the Channel Key packet immediately but
1375 putting it to queue. However, this is more fundamental problem:
1376 packets that are in queue should actually not be encrypted
1377 because packets that are sent immediately gets encrypted
1378 actually with wrong IV (and thus MAC check fails). So, packets
1379 that are in queue should be encrypted when they are sent to
1380 the wire and not when they put to the queue.
1382 However, the problem is that the current system has not been
1383 designed to work that way. Instead, the packet is encrypted
1384 as soon as possible and left to the queue. The queue is then
1385 just purged into wire. There won't be any fixes for this
1386 any time soon. So, the current semantic for packet sending
1389 o If you send packet to remote host and do not force the send
1390 (the packet will be in queue) then all subsequent packets to the
1391 same remote host must also be put to the queue. Only after the
1392 queue has been purged is it safe again to force the packet
1395 o If you send all packets immediately then it safe to send
1396 any of subsequent packets through the queue, however, after
1397 the first packet is put to queue then any subsequent packets
1398 must also be put to the queue.
1400 Follow these rules and everything works fine.
1402 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1404 * Added new function silc_server_remove_clients_by_server to
1405 remove all client entries from ID list when the server connection
1406 is lost. In this case it is also important to invalidate all
1407 client entires as they hold the invalid server entry. This
1408 fixes fatal bug when server has lost connection and will reconnect
1411 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Made some sanity checks to silc_server_daemonise like to check
1414 whether the requested user and group actually exists.
1416 * Added sanity check to SKE's silc_ske_responder_finish to check
1417 that the public and private key actually is valid.
1419 * Invalidate the client's nickname when receiving Replace ID
1420 packet and the Client ID is being replaced. This means that the
1421 server will query the nickname if someone needs it (client)
1424 * Sort the ID Cache in client library when the ID Cache data
1425 has changed (needs sorting).
1427 * Do not allow for SILC client to create several connections to
1428 several servers. The client does not support windows right now
1429 and generating multiple connections causes weird behaviour.
1431 Irssi-silc client does support windows and can handle several
1432 connections without problems, see: www.irssi.org and SILC plugin.
1434 * Fixed some places where client was added to the IDList. The
1435 rule of thumb is following (in order to get everything right):
1436 If the client is directly connected local client then the
1437 `connection' argument must be set and `router' argument must be
1438 NULL to silc_idlist_add_client function. If the client is not
1439 directly connected client then the `router' argument must
1440 bet set and the `connection' argument must be NULL to the
1441 silc_idlist_add_client function.
1443 * The funtion silc_server_packet_send_local_channel actually did
1444 not check whether the client was locally connected or not. It
1445 does that now. Fixed a bug related to LEAVE command.
1447 * Fixed Remove Channel User payload parsing bug in server's
1448 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1450 * The server's silc_server_save_channel_key now checks also the
1451 global ID list for the channel as it might not be in the local
1452 list. Fixed a bug related to LEAVE command.
1454 * Is this the end of the [<unknown>] buglet that has been lurking
1455 around for a long time? A little for loop fix in server's
1456 silc_server_command_whois_parse that is used by both IDENTIFY
1457 and WHOIS command. At least, this was a clear bug and a cause
1458 of one type of [<unknown>] buglet.
1460 * WHOIS and IDENTIFY commands call the function
1461 silc_server_command_[whois/identify]_check function even if
1462 we are not router server.
1464 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1466 * Added --with-gmp configuration option. If set the GMP
1467 is always compiled in the SILC source tree. If not set then
1468 it is checked whether the system has the GMP3 installed. If
1469 it has then the GMP won't be compiled (the system's headers
1470 and library is used), if it doesn't have it then the GMP is
1471 compiled in the SILC source tree.
1473 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Changed RSA private exponent generation to what PKCS #1
1476 suggests. We try to find the smallest possible d by doing
1477 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1478 not security fix but optimization.
1480 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Added new config entry [Identity] to fork the server and run
1483 it as specific user and group. A patch from Bostik.
1485 * Imported Dotconf configuration library into lib/dotconf.
1486 This will be used to create the SILC configuration files later.
1487 It will appear in the distsribution after this commit.
1489 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * A big code auditing weekend happening. Auditing code for
1492 obvious mistakes, bugs and errors. Also, removing any code
1495 Removed files for being obsolete:
1497 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1498 inline in the file lib/silcutil/silcbuffer.h)
1500 o lib/silcutil/silcbufutil.c (the header has inline versions)
1502 Changed code to fix possible error conditions:
1504 o The buffer formatting routines now check that the destination
1505 buffer really has enough space to add the data. This applies for
1506 both buffer formatting and unformatting
1507 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1508 unformatting was changed to accomodate following rules:
1509 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1510 sent to the function while XXX_*STRING will not allocate or copy
1511 the data into the buffer. Instead it sets the pointer from the
1512 buffer into the pointer sent as argument (XXX_*STRING used to
1513 require that the pointer must be allocated already). This change
1514 makes this whole thing a bit more consistent and more optimized
1515 (note that the data returned in the unformatting with XXX_*STRING
1516 must not be freed now). The routines return now -1 on error.
1518 o Tried to find all code that use buffer_format and buffer_unformat
1519 and added return value checking to prevent formatting and
1520 especially unformatting errors and possible subsequent fatal
1523 o Changed ske->x and ske->KEY to mallocated pointers in
1524 lib/silcske/silcske.h. Fixed possible data and memory leak.
1526 o Added return value checking to all *_parse* functions. Fixed
1527 many memory leaks as well.
1529 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1530 so that buffer overflows would not happen. All code now also
1531 checks the return value as it can fail.
1533 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Added reconnection support to server if the normal server looses
1536 its connection to the router (for example if router is rebooted).
1537 The server performs normal reconnection strategy implemented
1538 to the server. Affected file silcd/server.c.
1540 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Added new packet type SILC_PACKET_SET_MODE that is used to
1543 distribute the information about changed modes (for clients,
1544 channels and clients channel modes) to all routers in the
1545 network. Updated the protocol specification accordingly.
1547 Added functions into silcd/packet_send.c and
1548 silcd/packet_receive.c: silc_server_send_set_mode,
1549 silc_server_set_mode.
1551 Added new files silcmode.[ch] into lib/silccore that implements
1552 the encoding and decoding of Set Mode Payload. Added new type
1553 SilcSetModePayload. Moved the definitions of different modes
1554 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1556 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Oops, a little mistake in server's connection authentication
1559 protocol. The protocol is not ended with FAILURE but with
1560 SUCCESS if the authentication is Ok. :) Affected file is
1563 * Implemented NICK_CHANGE notify handling in server in the file
1564 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1565 the local clients on the channel. After the changing nickname
1566 in router environment snhould work and the [<unknown>] nickname
1567 should appear no more.
1569 The silc_server_replace_id function that receives the Replace ID
1570 payload now sends the NICK_CHANGE notify type also in the file
1571 silcd/packet_receive.c
1573 * Changed WHOIS and IDENTIFY command to support the maximum amount
1574 of arguments defined in protocol specs (3328 arguments). This
1575 fixed a bug that caused problems when there were more than three
1578 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added extra parameter, command identifier, to the
1581 silc_client_send_command so that explicit command identifier
1584 Changed that ID list routines uses specific command identifier
1585 when sending WHOIS/IDENTIFY requests to the server so that they
1586 can be identified when the reply comes back.
1588 Affected files lib/silcclient/command.[ch],
1589 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1591 * Added `sender' argument to silc_server_packet_send_to_channel
1592 to indicaet the sender who originally sent the packet to us
1593 that we are now re-sending. Ignored if NULL. Affected file
1594 silcd/packet_send.[ch].
1596 * Added some server statistics support in silcd/server_internal.h
1597 SilcServerStatistics structure and around the server code. Also
1598 send some nice statistics information when client is connecting
1601 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Fixed channel ID decoding in server's JOIN command reply in
1604 silcd/command_reply.c
1606 * Fixed braodcasting of replace ID payload to not to send it if
1607 we are standalone server in silcd/packet_receive.c.
1609 * Fixed all channel message sending routines to not to send
1610 packets to clients that has router set, since they are routed
1611 separately in the same function earlier. Affects file
1612 silcd/packet_send.c and all channel packet sending functions.
1614 * In USERS reply, res_argv[i] are not allocated, the table
1615 is allocated. Thus changed that free the table, not its
1618 * In server's whois_check and identify_check if the client is
1619 locally connected do not send any WHOIS commands - they are not
1622 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Fixed some minor bugs in client when sending WHOIS command. The
1625 arguments was in wrong order.
1627 * Removed statis function add_to_channel from server in
1628 silcd/command.c that was previously used with the joining but
1631 * Tested USERS command in router environment successfully with two
1632 routers, two servers and two clients.
1634 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1636 * Reorganized the USERS command and command reply in client library
1637 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1638 When the command is given by user we register a pending command
1639 callback that will reprocess the command after the reply has been
1640 received from the server. When reprocessing the packet we then
1641 display the information. Thus, the USERS information is displayed
1642 now in the command callback instead of in the command reply
1643 callback. The processing of the command is same as previously
1644 when server has sent the command reply in the JOINing process.
1646 * Added to USERS command in silcd/command_reply.c to join the client,
1647 we didn't use to know about, to the channel after we've created
1648 a client entry for it. Also, for clienet we did know already still
1649 check whether it is on the channel or not and add it if not.
1651 * Removed silc_server_command_join_notify as the function and its
1654 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1656 * Changed the client's pending command handling to the same as the
1657 server's pending command handling. It is also now possible to
1658 execute command reply functions from other command reply
1659 function as the function callbacks for commands and command
1660 replies are one and same. The pending commands are not static
1661 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1662 in client connection context. Thus, pending commands are server
1663 connection specific as it is convenient.
1665 Changed the function silc_client_command_pending and
1666 silc_client_command_pending_del and added new function
1667 silc_client_command_pending_check. Removed the
1668 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1671 * Added cmd_ident, current command identifier, to the client
1672 connection context in lib/silcclient/client.h to keep track on
1673 command identifiers used in command sending. Client's command reply
1674 function handling now supports the mandatory command identifiers.
1676 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1677 funtions in client to fully support pending command callbacks.
1679 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1680 as one of the arguments to the application in the command reply
1683 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1684 before first releasing SILC but came back. Now it is removed again
1685 and should come back nomore. The FORWARDED flag was used only
1686 by the JOINing procedure by forwarding the command packet to router.
1687 Now, the JOINing procedure has been changed to more generic (due
1688 to various router environment issues) and FORWARDED is not needed
1689 anymore for anything. The protocol specification is yet to be
1692 Now, removed silc_server_packet_forward from server and the flag
1693 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1695 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Renamed NAMES command to USERS command. The NAMES was named that
1698 due to historical reasons. Now it is renamed. Also, rewrote
1699 parts of the USERS command. The nickname list is not sent anymore
1700 by the server. Only Client ID and mode lists are sent in the USERS
1701 command. Changed this also to the protocol specification.
1703 The client now resolves the names and stuff after it receives
1704 the USERS list from the server when joining to the channel.
1706 * WHOIS and IDENTIFY commands has been changed to support multiple
1707 Client ID's per command. One can now search for multiple users
1708 in the network by sending only one WHOIS or IDENTIFY command.
1709 Changed the code and the protocol specifications.
1711 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1712 uses silc_server_command_whois_parse to parse the request. */
1714 * If normal server, do not parse the WHOIS and IDENTIFY requests
1715 before sending it to the router. Saves some time.
1717 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Fixed JOIN command on client library. Wrong number of arguments
1720 used to crash the client.
1722 * Added silc_server_channel_has_global function to check whether
1723 channel has global users or not.
1725 * Added silc_server_channel_has_local function to check whether channel
1726 has locally connected clients on the channel.
1728 * The silc_server_remove_from_one_channel now checks whether the
1729 channel has global users or not after given client was removed from
1730 the channel. It also checks whether the channel has local clients
1731 on the channel anymore. If it does not have then the channel entry
1732 is removed as it is not needed anymore.
1734 * The silc_server_notify now checks on JOIN notify whether the joining
1735 client is one of locally connected or global. If it is global then
1736 the channel has now global users on the channel and that is marked
1737 to the channel entry. Also, it now saves the global client to
1738 global list who is joining and JOINs it to the channel. This is
1739 for normal server, that is.
1741 Changed silc_server_send_notify_on_channel,
1742 silc_server_packet_relay_to_channel and
1743 silc_server_packet_send_to_channel check if we are normal server
1744 and client has router set (ie. global client) do not send the
1745 message to that client, as it is already routed to our router.
1747 * Implemented LEAVE notify type handling in silc_server_notify
1750 * Tested LEAVE command in router environment successfully. Tested
1751 with two routers, two servers and two clients.
1755 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1757 * Implemented SIGNOFF notify type handling in silc_server_notify
1760 * silc_server_remove_id now removes the client entry from all channels
1761 it has joined and thusly sends SIGNOFF notify type.
1763 * Rewrote the NAMES list generation in server by removing two excess
1764 loops. The lists are created now inside one loop.
1766 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1768 * silc_server_remove_channel_user checks now also global list
1769 for channel and client.
1771 * silc_server_new_channel_user checks now both local and global
1772 list for channel and client. Fixed a bug in client id decoding.
1773 Used to decode wrong buffer.
1775 * silc_server_channel_message checks now both local and global
1776 list for channel entry.
1778 * Tested channel joining (hence JOIN) in router environment
1779 successfully. Tested with two routers, two servers and two
1782 * Tested channel message sending in router environment successfully.
1784 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Added silc_server_save_channel_key into server.[ch] to save the
1787 received channel key in Channel Key payload processing. It is
1788 also used in JOIN command reply handling.
1790 Equivalent function silc_client_save_channel_key added into
1791 client.[ch] into client library.
1793 * Changed JOIN command reply to send information whether the channel
1794 was created or not (is existing already) and the channel key
1795 payload. Changed protocol specs accordingly.
1797 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1798 the request was sent by ID and not by nickname. Crashed on
1801 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1804 now correctly save the received data.
1806 * silc_server_free_sock_user_data now notifies routers in the
1807 network about entities leaving the network.
1809 At the same time implemented functions silc_server_remove_id
1810 and silc_server_send_remove_id to receive and send REMOVE_ID
1811 packets. The packet is used to notify routers in the network
1812 about leaving entities. The ID removed will become invalid in
1815 * Added function silc_idlist_del_server into server. Removes and
1816 free's server entry from ID list.
1818 * silc_server_private_message function now checks, if we are router,
1819 that the destination ID really is valid ID, naturally.
1821 * In router when NEW_ID packet is received (for new client) the
1822 hash of the Client ID is saved in the ID Cache but the
1823 client->nickname is set to NULL, instead of putting the hash
1826 IDENTIFY command now also checks that client->nickname must be
1827 valid. If it is not if will request the data from the server who
1828 owns the client. Added new function
1829 silc_server_command_identify_check.
1831 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1832 to set the command to already allocated Command Payload.
1834 * Tested private message sending in router environment with two
1835 routers, two servers and two clients. Fixed minor bugs and now
1838 * Fixed segfault from client's NAMES command. Used to crash if
1841 * Forwarded packets must not be routed even if it is not destined
1842 to the receiver. Changed server code comply with this.
1844 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Added `require_reverse_mapping' boolean value to ServerParams
1847 structure. If TRUE (not default) the server will require that
1848 the connecting host has fully qualified domain name.
1850 If the reverse mapping is not required and hostname could not be
1851 found the IP address is used as hostname.
1853 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Implemented version string checking to both client and server.
1856 The check is incomplete currently due to the abnormal version
1857 strings used in development version of SILC.
1859 * Changed all command functions in server to use the new
1862 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Changed char *data to unsigned char *data in ID Cache system to
1865 support binary data as ID Cache data. Changed code to support
1866 binary data in lib/silccore/idcache.c.
1868 * Renamed silc_server_packet_relay_command_reply to
1869 silc_server_command_reply as it is normal packet receiving
1870 function. Rewrote the function to accept command replys for
1871 servers and not only for clients.
1873 * Mark remote router always as registered server if we are connecting
1874 to it. Otherwise, commands sent by the router to us are ignored.
1876 * All ID List find routines now returns the ID Cache Entry pointer
1877 as well if requested.
1879 * WHOIS command works now in router environment, tested with two
1880 routers, two servers and two clients.
1882 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1883 in router environment (as it is almost equivalent to WHOIS) but
1884 hasn't been tested thoroughly. Added new functions:
1886 silc_server_command_identify_parse
1887 silc_server_command_identify_send_reply
1888 silc_server_command_identify_from_client
1889 silc_server_command_identify_from_server
1891 * Disabled route cache adding because adding two different ID's with
1892 same IP replaces the old cache entry thus giving wrong route.
1893 The entry->router->connection is always the fastest route anyway
1894 so route cache may not be needed. Of course, new routes maybe
1895 established after receiving the ID when the entry->router->connection
1896 might not be anymore the most optimal.
1898 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Add route cache for received ID for fast routing.
1902 * Added silc_server_packet_route to route received packet on router
1903 that is not destined to us.
1905 * Renamed silc_server_get_route to silc_server_route_get.
1907 * Added id_string and id_string_len fields into SilcServer to
1908 include encoded ServerID for fast comparing without excess
1909 encoding of the ID's.
1911 * Cleaned up WHOIS command on server side. Added following static
1914 silc_server_command_whois_parse
1915 silc_server_command_whois_check
1916 silc_server_command_whois_send_reply
1917 silc_server_command_whois_from_client
1918 silc_server_command_whois_from_server
1920 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1921 arguments in command replies. All command functions should be
1922 updated to use this macro.
1924 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Minor typo fixes on command reply handling on server.
1928 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Added silc_server_command_add_to_channel internal routine to add
1931 the client to the channel after router has created the channel and
1932 sent command reply to the server.
1934 * Added generic silc_server_send_command to send any command from
1937 * Use static buffer with ID rendering instead of duplicating data.
1939 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Fixed a channel user mode bug when joining to a channel server gave
1942 everybody channel founder rights, oops.
1944 * We mark ourselves as the router of the incoming server connection
1945 if we are router ourselves. This way we can check in some packet
1946 sending functions whether it is locally connected server. For
1947 incoming router connections we put NULL.
1949 * For router sending packets locally means now always sending the
1950 packet cell wide; to local clients and local servers. For normal
1951 server sending packet locally means sending it to only local
1954 * Fixed the JOIN command to really work in router environment. If the
1955 channel is created it is always created by the router. Router is
1956 also responsible of making the initial joining to the channel,
1957 sending JOIN notify to the sending server and distributing
1958 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1959 does not exist server doesn't do anything else but forward the
1960 command to the router which performs everything.
1962 * Added silc_server_send_channel_key function to send the Channel Key
1965 * Added silc_server_create_channel_key to create new channel key. The
1966 channel key is now re-generated everytime someone joins or leaves
1967 a channel, as protocol dictates. Note: channel->key_len is the
1970 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1973 packet_receive.[ch] to separate packet sending and receiving
1974 routines. The server.[ch] now includes everything else including
1975 actual packet processing (writing and reading data) and other
1978 Renamed silc_server_private_message_send_internal to
1979 silc_server_send_private_message. The routine is still though
1980 used only to relay private messages as server does not send
1981 private messages itself.
1983 Renamed silc_server_new_channel to silc_server_create_new_channel
1984 and added new function sicl_server_new_channel that handles the
1985 incoming New Channel packet. Added also new sending function
1986 silc_server_send_new_channel to send New Channel Payload.
1988 * Added new function silc_server_notify to process incoming notify
1989 packet to the server/router. Server may then relay the notify
1990 to clients if needed.
1992 * Added new function silc_server_new_channel_user to process incoming
1993 New Channel User packet. Router will redistribute the packet and
1994 send JOIN notify to its local clients and locally connected servers
1995 if needed. Normal server will send JOIN notify to its local client
1996 on same channel when received this packet. Added also corresponding
1997 sending function silc_server_send_new_channel_user to sent the
2000 * Added boolean route argument to send_notif_to_channel and
2001 packet_send_to_channel functions to attempt to route the packet
2002 if it is TRUE and send only locally if it is FALSE.
2004 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * silc_server_replace_id now broadcasts the received replace ID
2007 packet if it is not broadcast packet already. The router must
2008 broadcast to inform other routers about changed ID.
2010 * Added backpointer to server's router into SilcServer context in
2011 silcd/server_internal.h.
2013 * Fixed silc_server_packet_broadcast to send correct broadcast
2016 * The channel key is now distributed to the local client as soon
2017 as it is received from the router (in router environment) so that
2018 no other packet may be sent for the channel until client has
2021 * silc_server_remove_channel_user now broadcasts the received
2022 Remove Channel User packet if it is not broadcast packet already.
2023 The router must broadcast to inform other routers about removed
2026 * Added users field into SilcPacketContext that is a reference count
2027 of the context. One can increase the reference count by calling
2028 silc_packet_context_dup which is now changed to just increase the
2029 reference count instead of duplicating the data. The reference
2030 count is decresed by calling silc_packet_context_free that will
2031 free the data after the reference count hits zero.
2033 For now on the packet context and everything allocated into it
2034 (including the raw packet from network) must be freed by calling
2035 the new silc_packet_context_free function. Added also new function
2036 silc_packet_context_alloc that must be used now to allocate the
2037 context. This also means that if a routine is asynchronous from
2038 silc_[client/server]_packet_parse_type the packet context must
2039 be duplicated by calling silc_packet_context_dup. Otherwise it
2040 gets free'd after silc_[client/server]_packet_parse_type returns.
2041 Also, one must remember that if packet is duplicated then its
2042 reference count must be decresed by calling the free function as
2043 many times as it was duplicated.
2045 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2046 from both client and server.
2048 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Made joining to a channel working in router environment.
2052 * Cleaned up JOIN command on server side and create function
2053 silc_server_command_join_channel internal routine to make the
2056 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Changed silc_command_pending list to SilcDList. Also, added
2059 `ident' field to SilcServerCommandPending structure to identify
2060 the reply and to call correct callback.
2062 Added silc_server_command_pending_check function to replace the
2063 corresnponding macro. The silc_command_pending list is not
2066 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2067 to set identifier to previously allocated Command Payload. It
2068 is used to set identifier for command when resending Command
2071 * Added silc_command_payload_encode_payload to encode Command
2072 Payload buffer from SilcCommandPayload structure.
2074 * Added silc_argument_payload_encode_payload to encode Argument
2075 payload buffer from SilcArgumentPayload structure.
2077 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Changed WHOIS command to support router connection on server side.
2080 The whois request is always sent to router unless the server is
2081 standalone server. After server has received the reply from the
2082 router will it send the reply to the client.
2084 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2085 broadcast received broadcast packet. The function is used only
2086 by router. The broadcast packet is always sent to the router's
2089 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2090 render given ID to printable string, for log files for example.
2092 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Made basic router to router connections working. At least they
2095 can now connect to each other but nothing really works the way
2096 they are supposed - yet.
2098 * Added new initiator token to RouterConnection configuration
2099 file in silcd/serverconfig.[ch]. It is used to tell whether we
2100 are the initiator to the remote router or whether we'll expect
2101 the other end to connect.
2103 * Moved registering of listener task to silc_server_init, hence
2104 the server starts listenning as soon as it is run, even if it
2105 does not have connections to other routers. Let's see how well
2108 * Changed default connection retry timeouts for more suitable in
2111 * Removed cipher and such arguments from silc_idlist_add_client
2112 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2113 Added new function silc_idlist_add_data to add the keys and stuff
2116 * Added SilcIDListData structure and added it to SilcClientEntry
2117 and SilcServerEntry as their first field in the structure. This
2118 way we can explicitly cast the ID entries to the SilcIDListData
2119 structure and get common data for the entries. In past, we had
2120 to first check what type of connection it is and then cast it to
2121 correct ID entry type. Now, we can directly cast the opaque
2122 pointer to the SilcIDListData (no matter what ID entry it actually
2123 is) and get the data needed.
2125 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2128 in some circumstances even if threre were timeout tasks, though not
2129 IO tasks, but tasks anyway. Now fixed.
2131 * Defined SilcServerConnection structure to hold connection specific
2132 stuff about directly connected servers and routers. The definition
2133 is currently in silcd/server_internal.h. I thought about having
2134 a bit more important role fro this struct but for now it is used
2135 only when connecting to other server (or router actually).
2137 * Added connecting retry support in server when connecting to
2138 router(s). The retry feature implement exponential backoff
2139 algorithm. Also, added SilcServerParams structure to hold default
2140 parameters for server. For now, it include these retry settings
2141 and are hard coded. After server is moded to be as Silc Server
2142 Library this structure will be more important.
2144 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Changed client librarys channel->clients table to SilcList and
2147 changed code accordingly.
2149 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Changed client's channel table to SilcList and changed code
2152 accordingly. Also changed SilcChannelClientEntry to include back-
2153 pointer to the channel so that client entry can use that structure
2154 as list as well and we have fast cross-reference to the channel.
2155 This change dramatically decreased the complexity of channel
2156 handling with client entry and vice versa (removed one extra
2157 loop when searching for channel entry from many functions).
2159 * Changed server->sim from table to SilcDList and changed code
2162 * NAMES command can now be used from user interface. It will show
2163 the user list on the channel, neatly.
2165 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2166 Code now saves realname of the user if it becomes available.
2168 * Renamed configure.in to configure.in.pre and made ./prepare
2169 script to automatically add correct version string to
2170 configure.in which it creates from configure.in.pre.
2172 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * NAMES command reply now shows users mode with the nickname when
2177 * Moved silc_client_ch[u]mode[_char] functions from
2178 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2179 place sucks, they are utility functions and should be in some
2182 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2184 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2187 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Added TRQ (efficient deque and list library) into lib/trq. This is
2192 a very good list library that is currently used in the SILC. Defined
2193 SilcList API over the library because I didn't like the API very
2194 much. See lib/trq/silclist.h for the API and examples of how to
2195 use the API. Fixed various places in the code to use the new
2196 SilcList API. The SilcList is meant for lists that has a structure
2197 already defined as a list. It is not suitable to add just some
2198 context to the list (in TRQ, the context is the list actually).
2200 So, I defined SilcDList that can be used for the purpose where
2201 predefined list structure does not exit. This can be used as
2202 such list. Now some context just can be added to the SilcDList.
2203 Currently this list is not used in the SILC just yet, though there
2204 are a lot places where this can replace dynamically allocated
2205 tables and I will fix these places, later, to use SilcDList.
2206 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2207 and use TRQ internally).
2209 Also fixed some annoying warning messages that the original TRQ
2210 code generated. Also minor changes to TRQ's Makefile.in.
2212 * Added support for querying by Client ID to both WHOIS and
2213 IDENTIFY commands into server, as required by the protocol.
2215 * Removed method function pointers from SilcBuffer structure. They
2216 weren't used to anything and just increased the context size for
2217 no good reason. This change also made silc_buffer_alloc and
2218 silc_buffer_free functions inline functions.
2220 * Disabled command flooding detection support until it's fixed so
2221 that it accepts commands in but does not execute them more than once
2224 * Added silc_net_localhost(), to return local hostname, into
2225 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2226 that must be initialized before calling silc_client_init.
2228 * Added new function: silc_server_send_notify_on_channels to send
2229 notify messages to all channels client has joined. It is assured
2230 that the message is sent only once per client.
2232 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2233 lib/silcutil/silcutil.[ch] as silc_format function. The new
2234 function is generic and is used by server as well, not only by
2235 the logging routines.
2237 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2238 the provided version string was not acceptable. Added new function:
2239 silc_ske_check_version into lib/silcske/silcske.h. The function
2240 must be implemented by the application (client or server) and it
2241 does not reside in the SKE library. The function checks the version
2242 string remote end sent.
2244 * Added back pointers (to opaque context and to SilcSocketConnection)
2245 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2247 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2248 duplicate packet context structure.
2250 * Changed `notify' client operation to send same arguments as client
2251 receives from server except for ID's. ID's are mapped to correct
2252 ID entry and that is returned. Also, if channel entry is not sent
2253 by server but the notify is for channel the channel entry is sent
2254 to application (otherwise application doesn't know that it is for
2255 channel (library gets it from packet's Destination ID)).
2257 * Added silc_client_remove_from_channels into client library to
2258 remove a client from all channels it has joined to. Used when
2259 received SIGNOFF notify from server. Added also new function
2260 silc_client_replace_from_channels to replace old ID entry with
2261 new ID entry on all channels. Used when received NICK_CHANGE
2264 * Fixed ID Cache list handling in silc_idlist_get_client in
2265 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2266 to get (or query) client by ID.
2268 * Updated TODO list.
2270 * Added connection authentication status message defined by the
2271 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2272 support for these into the code in client and server side.
2274 * Added generic function silc_client_send_command to send any command
2275 with variable argument list. Application should use this function
2276 to send commands if the command functions provided by the library
2277 does not suite for the application's user interface needs.
2279 * Added new `failure' client operation. Application is notified about
2280 received failure packet if client is executing a protocol. In this
2281 case the protocol's execution has failed.
2283 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2284 is required by the protocol.
2286 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2287 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2290 * Added status flag to SilcSKE object to indicate realtime status
2291 of the SKE protocol.
2293 * Application receives now exactly same command reply arguments as
2294 the library receives from server. However, if ID is received the
2295 corresponding ID entry is returned to the application (eg. Client
2296 ID is mapped to correct SilcClientEntry entry and that is returned).
2297 Changed command_reply client operation due to this change.
2299 * Changed all ID's in commands and in command replys as ID Payloads.
2300 Change affected both client and server side codes.
2302 All ID's sent in SILC network (with execption of ID's in SILC
2303 Packet header) are sent in ID Payload to support variable length
2306 * Server now notifies nick changes and notifies all clients on
2307 the channels about the new nickname (about the new Client ID,
2310 * Implemented CMODE command to change channel modes. Supports all
2311 channel modes defined by the protocol specs except ban and invite
2312 lists. (Also, private channel key mode is supported but support for
2313 setting private channel key in client is missing, thus, this mode
2314 has no effect on client side (except that server requires that the
2315 client uses private channel key and normal channel traffic does not
2318 Also, invite mode works per se, but INVITE command does not work
2319 yet correctly, so you can set channel as invite only channel but
2320 inviting clients to the channel does not work (it is yet to be
2321 thought what's the best way to do it).
2323 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2324 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2325 Implemented CUMODE command to change user's mode on the channel.
2326 Supports all modes defined by the protocol specs.
2328 * Added NAMES command reply to return users modes on the channel.
2330 * Removed unnecessary and slow ciphers from lib/silccrypt.
2332 * Set SO_KEEPALIVE option to connection sockets by default.
2334 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2336 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2337 redefined the Notify Payload into protocol specs.
2339 * Added silc_id_payload_parse_id to get ID directly from raw
2342 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2345 accept searching by Client ID as well.
2347 * Added support for LEAVE and SIGNOFF notify types in client library.
2349 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2350 to parse ID Payload from raw data.
2352 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Added flags parameter into silc_ske_assemble_security_properties
2355 function in lib/silcske/silcske.[ch].
2357 * Changed notify client operation to fit better for notify messages
2358 sent by server. The notify payload received from server is now
2359 passed to the application (after parsing it to SilcNotifyPayload).
2360 It is application's responsibility to retrieve the arguments
2361 from the payload and show the message the way it wants. The message
2362 sent by server is implementation specific.
2364 * Changed public keys to comply with the protocol specification.
2365 Old public keys are not supported anymore and are not compatible.
2367 * Removed nickname from Channel Payload as the latest draft removed
2368 it. The client must resolve the nickname from the NAMES command
2369 reply received when it joined the channel.
2371 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2373 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Fixed some errors in protocol specification drafts.
2377 * Created lib/silccore/silcnotify.c to implement Notify Payload
2378 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2379 generic payloads described by protocol specifications. The file
2380 includes implementations for ID Payload and Argument Payload.
2382 * Changed Command Payload implementation to use the new Argument
2383 Payload. Changed command_xxxx_payload to command_payload_xxxx
2384 to comply with SILC coding conventions.
2386 * Added suppport for Argument Payload handling in Notify Payload
2387 implementation as protocol requires it. Added the new support
2388 into server and client lib as well.
2390 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Added support for multiple nicknames on same channel. [n] is
2393 added locally to the nickname if there are more than one same
2394 nicknames on the channel.
2396 * Server now sends all nicknames that matched WHOIS request.
2397 Client also shows the list received from server.
2399 * Added TOPIC command to client side. User can now set and show
2400 current topic on channel.
2402 * Added MOTD command to client and server. Also, server sends the
2403 motd when client connects to the server.
2405 * Changed version strings to comply ISO 8601.
2407 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Fixed protocol error handling in client library. It should now
2410 cope even if the SKE fails for some reason.
2412 * Made new protocol specification drafts for submitting to IETF.
2414 * Implemented TOPIC command to server in silcd/command.c.
2416 * Added two new notify types into lib/silccore/silcnotify.h:
2417 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2418 notify nickname change and topic setting/change on a channel.
2420 * API change of command_reply operation in client library. The
2421 application gets now the status type received from server as well.
2423 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2427 * Cras fixed and optimized the packet handling even further and
2428 it should work now. Minor change to the prototype of function
2429 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2431 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Added new function into lib/silcutil/silcschedule.[ch]:
2434 silc_schedule_with_fd to select() a specified fd. The function
2435 returns after timeout expires or data arrives or goes. The
2436 function is used by packet routines to wait that all data is
2437 received from network.
2439 * Fixed data reading from network in lib/silccore/silcpacket.c.
2440 The code now assures that all data is read from the fd and then
2441 continues packet processing. This was a bug fix since the code
2442 used to drop some data in some circumstances.
2444 * Added new function into lib/silcclient/client.[ch]:
2445 silc_client_start_key_exchange to start key exchange after
2446 connection has been established to server. The code internally
2447 now uses this funtion but its main purpose was to provide it
2448 for applications that perform their own connecting. After
2449 application has created a connection it merely calls this
2450 function to start the key exchange between client and server.
2451 The library takes care of everything else after that.
2453 Updated also lib/silcclient/README to explain the usage of
2456 * Do not send to application information that connection has
2457 been established. Application gets notified it by connect
2460 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Applied cras's patch to add silc_schedule_one function. The
2463 function runs scheduler once and returns.
2465 * Fixed the scheduler after cras messed it up. The timeout
2466 handling works now as it's supposed to work.
2468 * Added into lib/silccore/ silcnotify.h to include notify
2469 message types support. Changed silc_server_send_notify*
2470 functions, in server.[ch], to support those new notify types.
2471 Added the support for the notify types into client library,
2472 as well. Added new notify client operation into ops.h in
2475 * Changed silc_server_packet_send_to_channel to send normal
2476 packets instead of just channel message packets. The function
2477 is now used to send the notify packets to channels. It is not
2478 used to send channel message packets anymore, as server never
2481 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2482 va_arg()s as it seems to require it nowadays. I guess, if SILC
2483 is compiled with older va_arg() the new code should work anyway.
2485 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Splitted core library. Core library (lib/silccore) includes
2488 now only SILC protocol specific core (and common) components.
2489 Created new utility library (lib/silcutil) that includes more
2490 generic purpose stuff. The stuff for util library was taken
2491 from the old core library. This was minor and easy split.
2493 * Created SILC Client Library (lib/silcclient) that includes
2494 implementation of the SILC client without user interface. This
2495 was major move from silc/ directory. The code has been changed
2496 so that it is transparent towards the user interface. The
2497 silc/ directory includes now the same user interface as before
2498 and it uses the new client library. Read lib/silcclient/README.
2499 Basicly, the client library performs everything else related
2500 to SILC except user interface handling. Also, configuration
2501 files are considered to be part of user interface and library
2502 does not handle them.
2504 This change also changed a lot of structures, function naming etc.
2505 Most important change was that SilcClientWindow object was
2506 renamed to SilcClientConnection in the client library. Created
2507 also new file lib/silcclient/ops.h. Also added new files
2508 silc/local_command.[ch] and silc/client_ops.[ch].
2510 All these changes were made to make it easier for user interface
2511 designers to create what ever user interface for the SILC client
2514 It is also expected that the server will be moved to lib
2515 directory as well and SILC Server Library will be created;
2516 sometimes in the future.
2518 * Removed Local commands from lib/silccore/silccommand.h as
2519 they are application specific and new client library does not
2520 handle any of those anymore.
2522 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2523 old client implementation in silc/.
2525 * Added support for callback functions in SILC_LOG_* macros.
2526 Application can now set its own callbacks that will be called
2527 instead of using the default functions that will always print
2528 the debug messages to stderr (or stdout). Also, debugging can
2529 now be disabled by setting silc_debug to FALSE and re-enabled by
2530 setting it to TRUE. Note, that logging will still work even
2531 if debugging is disabled.
2533 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2534 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2535 silc_log_reset_debug_callbacks.
2537 * To enable debugging in silc client one must give now -d
2538 option on command line.
2540 * Changed silc_schedule_init to automatically allocate task queues
2541 if they are not allocated before calling it.
2543 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Added GMP 3.1 into math library.
2547 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2550 a channel in SILC network. The packet is used by servers and
2551 routers to notify other routers that user has left a channel.
2552 This little feature was missing until now. Added the feature
2553 to protocol specification as well.
2555 Added functions: silc_server_send_remove_channel_user and
2556 silc_server_remove_channel_user into server.[ch].
2558 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2559 lib/silccore/silcpacket.h. However, they are not implemented
2562 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Fixed joining to a channel and sending channel messages
2565 between server and router. The channel message sending should
2566 now work inside a cell.
2568 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Fixed the private message sending between server and router.
2571 The private message sending should now work inside a cell.
2573 * Added silc_server_replace_id into server.[ch] to replace
2574 existing ID in the SILC network.
2576 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2577 and silc_idlist_replace_server_id into idlist.[ch] in server.
2579 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Fixed the server to server connections. Server can again now
2582 connect to router. Router to router connections probably does
2585 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added dynamic protocol registering support. Now protocols can
2588 registered and unregistered on the fly. Patch by cras.
2590 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Added lib/contrib directory to hold routines that some platforms
2593 don't have but are needed by SILC.
2595 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2596 into lin/contrib to provide getopt() and getopt_long() for
2597 those who don't have it.
2599 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added AWAY command to client. When away message is set and
2602 client receives a private message packet the client automatically
2603 replies to the sender with the away message.
2605 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2606 bug seemed to be the cause of recent problems when compiling
2609 * Added version detection support to SKE protocol specification
2610 and added the new changes to the SKE implementation as well.
2611 There were other minor changes in the SKE protocol as well.
2613 Many changes in lib/silcske/silcske.[ch] and in
2614 lib/silcske/payload.[ch].
2616 * Added ^U functionality, clear input line. Patch from cras.
2618 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Mainly small bugfixes on core library. Fixed some debugging
2621 logging and buffer overflow in silclog.c.
2623 * Updated config.sub and config.guess on the distribution tree.
2625 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Added command lagging support in server. Client may execute
2628 commands now only once in two seconds.
2630 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Optimized packet reception. MAC computation and checking is now
2633 also more optimized. A lot previously duplicated code is now
2634 used as generic by both client and server.
2636 * Fixed key pair generation in clientutil.c
2638 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Added into lib/silccore/silcbufutil.[ch] new function;
2641 silc_buffer_realloc.
2643 * Moved generic packet sending/encryption functions to
2644 lib/silccore/silcpacket.[ch] from client and server. Some
2645 rewriting of the functions.
2647 * Moved all generic packet reception/decryption functions to
2648 lib/silccore/silcpacket.[ch] from client and server. The
2649 packet processing is now much cleaner in both client and server.
2650 These were major changes in both client and server.
2652 * Created many common functions in server to do packet sending.
2653 Previously code were duplicated a lot, this has been removed
2656 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Rewrote major parts of the ID cache system. Don't know
2659 whether it is better now or not but at least the API is more
2662 * Major rewrite on ID cache stuff on client because of the ID
2663 cache API changes. Added idlist.c to client.
2665 * Also major rewrite on ID cache stuff on server as well.
2666 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2667 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2668 in hand, instead they are all put into the ID cache system now.
2669 All server_idlist_* routines uses ID cache now instead of
2670 traversing its own lists (those lists does not exist anymore).
2671 SilcIDList though still exists. Also, SilcXXXEntry's are
2674 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Finally made the SKE implementation compliant to the protocol
2677 specification. All mp integers are now binary encoded as
2678 opposed being HEX encoded.
2680 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2683 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2684 functions: silc_[encode/decode]_pem. Also added function
2685 silc_encode_pem_file to PEM encode with newlines ('\n') for
2688 * SILC public keys are now encoded either PEM or binary. Same
2689 option is for private keys as well. By default private keys
2690 are binary encoded and public keys PEM encoded. Silly HEX
2691 encoding were removed.
2693 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2694 function to create fingerprints.
2696 * Fixed a bug in SHA1; does not change the original data anymore.
2698 * Partly implemented INFO command on client and server side.
2699 Fixed CLEAR command. Changes to SERVER command; show current
2700 server(s) when giving command without arguments. Added
2701 VERSION command to client.
2703 * Added check to server that unregistered connections cannot
2704 execute commands (unless it is specificly allowed).
2706 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Fixed screen refresh.
2710 * Fixed channel joining bug from client. On some circumstances
2711 client tried to join to a channel it had already joined.
2713 * Added public key verification process into client's protocol.c.
2714 The client now verifies the public key from user and saves
2715 it into ~./silc/serverkeys/ directory.
2717 Added into: clientutil.[ch]: silc_client_verify_server_key.
2719 * Changed SKE protocol's silc_ske_initiator_finish function
2720 to accept callback function that verifies the received public
2721 key. Removed old silc_ske_verify_public_key function.
2723 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2726 silc_pkcs_private_key[_data]_set.
2728 * Made the password and public authentication more cleaner in
2729 server's protocol.c.
2731 * Removed historic and obsolete protocol `channel_auth' from
2732 both client and server.
2734 * Removed wrong way of sending command status messages from
2735 server to client in server's command.c. The old way violated
2736 protocol specification.
2738 Changes to silccore/silccommand.[ch]: removed
2739 silc_command_encode_status_payload -> not needed anymore,
2740 changed silc_command_encode_payload_va to accept extra
2741 argument on variable argument list. The argument type must
2742 now be provided to the function. Also, added new function:
2743 silc_command_encode_reply_payload_va which is same as
2744 normal command_encode_payload_va except command status type
2745 is provided as extra argument.
2747 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Added ~./silc directory handling. The directory includes the
2750 public and private keys for the client.
2752 Added silc_client_check_silc_dir, silc_client_create_identifier
2753 and silc_client_load_keys.
2755 * Implemented SILC protocol compliant public key. Added public
2756 and private key saving to and loading from files.
2758 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2759 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2760 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2761 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2762 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2764 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2765 silc_pkcs_load_[public/private]_key.
2767 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added silc_server_get_route (route.[ch]) to get connection
2770 data for the fastest route for given ID.
2772 * Implemented INVITE command on client and server. The command
2773 were re-defined in the SILC Protocol Specification and the
2774 implementation now complies with the specification.
2776 * Implemented PING command on client and server.
2778 * Implemented NAMES command on client and server. The server side
2779 supports currently only normal server not router server yet.
2780 Some changes to NAMES definition in SILC protocol specification.
2782 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Implemented LEAVE command on client and server.
2786 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2787 again. This change was made to the protocol as well. Server
2788 should not violate the protocol specification anymore.
2790 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2793 was tested. SOCKS4 was not but should work anyway.
