1 Thu Mar 29 15:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented the RESTART command in the client.
5 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6 notice type messages. Added notice printing to the user
9 * The channel keys are not re-generated if the channel's mode
10 is PRIVKEY, ie private key on the channel exists. Affected
11 files silcd/server.c and silcd/command.c.
13 * Fixed a little bug in channel message delivery when channel
14 private keys are set in the server. Affected file is
17 * Changed the setting on channel->on_channel = TRUE from the
18 silc_client_save_channel_key to the JOIN command reply. The
19 key payload is not received if the private channel key is set.
20 Affected file lib/silcclient/command_reply.c and the
21 lib/silcclient/client_channel.c.
23 * When the CMODE_CHANGE notify is sent and the channel private
24 key mode is removed the channel key must be re-generated in
25 other cells as well. Added this support for the router in the
26 silcd/packet_receive.c.
28 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * Added new local command ME to the client. It is used to send
31 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
32 some action. Affected file silc/local_command.[ch].
34 * Changed channel_message and private_message client operations
35 to deliver the message flags to the application. Added also
36 the `flags' arguments to the silc_client_send_channel_message
37 and silc_client_send_private_message functions. Affected file
40 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Redefined the Private Message Payload to support private message
43 keys and to support the new private message flags. Updated
44 the protocol specs. Flags makes it possible to have for example
47 * Added new type SilcPrivateMessagePayload and defined an API
48 for it in the lib/silcclient/silcprivate.[ch].
50 * Tested private message private keys successfully. Tested the
51 private message key set, unset and list commands with the new
54 * Redefined the Channel Message Payload to include the channel
55 message flags (equal with private message flags) to support
56 for example CTCP style messages.
58 * Defined some of the message (for channel and private message)
59 flags. Updated the protocol specs and added the flags to the
60 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
62 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Added SilcKeyAgreementStatus type to the key agreement routines
65 to indicate the current status and error if one occured.
66 The status types are defined in the lib/silcclient/silcapi.h.
68 * Added new local command KEY that is used to set and unset private
69 keys for channels, set and unset private keys for private messages
70 with remote clients and to send key agreement requests and
71 negotiate the key agreement protocol with remote client. The
72 key agreement is supported only to negotiate private message keys,
73 it currently cannot be used to negotiate private keys for channels,
74 as it is not convenient for that purpose.
76 * Fixed a minor pending callback setting bug in the function
77 silc_client_get_client_by_id_resolve, now the function works.
78 Affected file lib/silcclient/idlist.c.
80 * Added function silc_net_get_local_port to get local bound
81 port by socket. Added to lib/silcutil/silcnet.[ch].
83 * Added `sockets' and `sockets_count' fields to the SilcClient
84 object. They hold the sockets of the listenning sockets in
85 the client. Listenning sockets may be for example the key
86 agreement server. Affected file lib/silcclient/client.[ch].
87 Added functions the silc_client_add_socket and the
88 silc_client_del_socket. They are exported to the application
91 * Added ~./silc/clientkeys to support other client's public keys.
93 * Renamed verify_server_key client operation to verify_public_key
94 and added one argument to indicate the type of the connection
95 (server, client etc.).
97 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Added silc_server_connection_auth_request to handle the
100 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
101 silcd/packet_receive.[ch].
103 * Added silc_server_send_connection_auth_request into the
104 silcd/packet_send.c to send the connection auth request packet.
106 * Cleaned up the silcd/protocol.c a bit and fixed some memory
109 * Fixed the public key authentication in responder side in the
110 server. The `auth_data' pointer includes the SilcPublicKey
111 not the path to the public key. Affected file silcd/protocol.c.
113 * Implemented the public key authentication in the initiator side
114 in the server. Affected file silcd/protocol.c.
116 * Removed the [RedirectClient] config section from the server
117 configuration. Is not needed and I don't want to implement it.
119 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Cleaned up the CMODE command in the server. It now works
122 correctly and supports all the modes defined in the protocol.
123 Affected file is silcd/command.c.
125 * Added `hmac_name' field to the SilcChannelEntry in the server
126 to hold the default HMAC of the channel. It can be set when
127 creating the channel (with JOIN command). Affected files
130 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
131 type to indicate the change of the current cipher and hmac
132 on the channel. Client can safely ignore the <cipher> argument
133 (if it chooses to do so) since the CHANNEL_KEY packet will
134 force the channel key change anyway. The <hmac> argument is
135 important since the client is responsible of setting the new
136 HMAC and the hmac key into use.
138 * Fixed the CMODE command in the client library as well.
140 * Tested CMODE command in router environment successfully.
142 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Show the version of the remote client (or server) when connecting
145 to the server. It is logged to the log file. Affected file
148 * Fixed the KILLED notify handling in the client library. The
149 client must be removed from all channels when receiving the
152 Also, do not remove the client entry when giving the KILL
153 command but when the KILLED notify is received.
155 * Removed silc_idlist_find_client_by_nickname from the server.
156 Not needed anymore. Affected files silcd/idlist.[ch].
158 * Implemented the CHANNEL_CHANGE notify type handling to the
159 server. Affected file silcd/server.c.
163 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

166 notify between routers.
168 * Implemented the INVITE command correctly to the server.
170 * Implemented the INVITE notify type handling in the server.
172 * Implemented the INVITE command to the client library and on the
175 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Added function silc_server_get_client_resolve to find the
178 client entry by ID from all ID lists and then resolve it
179 (using WHOIS) if it cannot be found. Affected file is
182 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Implemented the BAN command to the client library.
186 * The JOIN command in the server now checks the invite list
189 * Changed the silc_command_reply_payload_encode_va and the
190 silc_command_payload_encode_va to support that if argument is
191 NULL it ignores and checks the next argument. Affected file
192 lib/silccore/silccommand.c.
194 * Added silc_server_send_notify_ban to send the BAN notify
195 type between routers.
197 * Chaned the silc_notify_payload_encode to support that if
198 argument is NULL it ignores and checks the next argument.
199 Affected file lib/silccore/silcnotify.c.
201 * Tested ban lists in router environment successfully.
203 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Implemented BAN command to the server, in silcd/command.[ch].
207 * Removed the BAN and INVITE_LIST modes from the CMODE command
210 * Added function silc_string_match to regex match two strings.
211 Affected files lib/silcutil/silcutil.[ch].
213 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Redefined parts of the SilcChannelEntry in the server to support
216 the new ban and invite lists.
218 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Redefined the INVITE command. The same command can be used to
221 invite individuals to the channel but also to manage the invite
222 list of the channel (to add to and remove from the invite list).
223 Updated the protocol specs.
225 * Added new command SILC_COMMAND_BAN that can be used to manage
226 the ban list of the channel. Updated the protocol specs.
228 * Removed the channel modes: the SILC_CMODE_BAN and the
229 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
230 in the CMODE command. The equivalent features are now available
231 using INVITE and BAN commands. Updated the protocol specs.
233 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
234 in the network about change in the current ban list. The notify
235 type is not used by the client.
237 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
238 support the invite lists.
240 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
242 * Added new function silc_string_regexify that converts string
243 including wildcard characters into regex string that can
244 be used by the GNU regex library. Added into the file
245 lib/silcutil/silcutil.[ch].
247 Added silc_string_regex_combine to combine to regex strings
248 into one so that they can be used as one regex string by
249 the GNU regex library. Added into the file
250 lib/silcutil/silcutil.[ch].
252 Added silc_string_regex_match to match two strings. It returns
253 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
255 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Imported GNU regex to the soruce tree into lib/contrib.
258 Fixed some compiler warning from the regex.c.
260 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed MOTD command in the server to work in router environment.
264 * Fixed the MOTD command in the client library to support
265 the server argument in the command.
267 * Added `nickname_len' argument to the silc_idlist_add_client
268 in the server, as the `nickname' argument may be binary data
271 * Added silc_idlist_get_channels to return all channels from
274 * Implemented LIST command to the server. Affected file is
277 * Implemented the LIST command to the client library and on the
280 * Added [<user count>] argument to the LIST command reply.
281 With private channels the user count is not shown.
283 * Updated TODO and README.
285 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * The client entry's data.registered must be TRUE even with
288 global client entry on global client list. The data.registered
289 is used to check whether the client is anymore in the network,
290 for example with WHOWAS command so it must be valid.
292 * Fixed the WHOWAS command in the server. It now actually works
293 in router environment. Added function into silcd/command_reply.c
294 silc_server_command_reply_whowas_save.
296 * Added silc_idlist_purge function to the silcd/idlist.c
297 to periodically purge the ID Cache.
299 * Fixed INFO command in the server. It works now in router
300 environment. Added <server name> argument to the INFO command
301 reply. Updated the protocol specs.
303 * Fixed minor bug in silc_idcache_purge to not purge if the
304 expire value is zero.
306 * Fixed various bugs in WHOIS and IDENTIFY command handling as
307 they were buggy because of the WHOWAS information.
309 * Fixed local command MSG to handle the async resolving of
310 the remote client properly. It used to fail the first MSG.
311 Affected file silc/local_command.c.
313 * Added `data_len' field to SilcIDCache context.
315 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * Update TODO. Todo in commands in the server.
319 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
322 used by routers as broadcast packet to inform other routers
323 about the changed user mode.
325 Implemented the notify handling in the server. Affected file is
326 silcd/packet_receive.c. Added the function
327 silc_server_send_notify_umode to the silcd/packet_send.[ch].
329 * Added new generic Channel Payload and deprecated the New Channel
330 Payload. The New Channel Payload is now the generic Channel
333 * Added new argument `mode' to the silc_server_send_new_channel
334 as it is required in the Channel Payload now.
336 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
337 and created a new and real SilChannelPayload to represent the
338 new generic Channel Payload. Implemented the encode/decode
339 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
341 * Added silc_server_get_client_channel_list to return the list
342 of channels the client has joined for WHOIS command reply.
343 Affected file silcd/server.[ch].
345 * Implemented the channel list sending in the WHOIS command reply
346 in server and in the client.
348 Implemented the channel list displaying on the user interface
349 as well. Affected file silc/client_ops.c.
351 * Added silc_channel_payload_parse_list to parse list of Channel
352 Payloads. It returns SilcDList list of SilcChannelPayloads.
353 Client for example can use this function to parse the list of
354 channels it receives in the WHOIS command reply. The caller
355 must free the list by calling silc_channel_payload_list_free.
356 Affected files lib/silccore/silcchannel.[ch].
358 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Added one new argument <user mode> to the WHOIS command reply
361 to return the mode of the user in SILC. Updated the protocol
364 Implemented it to the server and client.
366 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Fixed the mode printing on the user interface on joining.
369 Affected file silc/client_ops.c.
371 * Implemented the UMODE command and user modes in general to the
372 client library and to the user interface.
374 * Implemented the UMODE command to the server.
376 * The server now sends UNKNOWN_COMMAND error status if client sends
377 unknown command. Affected file silcd/command.c.
379 * All server commands now handle the command identifier the right
380 way when sending the command reply to the client. The client can
381 use to identify the command replies with the identifier.
383 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Added silc_server_get_client_route to resolve the route to
386 the client indicated by the client ID. Affected file is
389 * Added silc_server_relay_packet as general function to relay
390 packet to arbitrary destination. This deprecates functions
391 like _send_private_message_key, _relay_notify etc. Affected
392 file is silcd/packet_send.[ch].
394 Removed silc_server_send_key_agreement,
395 silc_server_send_private_message_key and
396 silc_server_packet_relay_notify functions from the file
397 silcd/packet_send.[ch].
401 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
402 server. Affected file silcd/packet_receive.[ch].
404 * Implemented the KILL command to the client. Implemented the
405 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
406 Affected files lib/silcclient/command[_reply].c and
407 lib/silcclient/client_notify.c. Implemented the KILL notify
408 printing in the user inteface.
410 * Fixed a lot silc_parse_nick memory leaks from the client
411 library in the file lib/silcclient/command.c.
413 * Changed the silc_server_send_notify_on_channels's `sender'
414 argument from SilcSocketConnection to SilcClientEntry to
415 check the sender as entry and not as connection object and not
416 to send to the client provided as argument. The affected file
417 is silcd/packet_send.[ch].
419 * The notify packets that are destined directly to the client used
420 to not to be processed by the server. Now changed that and the
421 server processes all notify packets. After relaying the packet
422 to the client the notify packet is processed in the server.
424 * The silc_server_free_client_data now checks whether there is
425 pending outgoing traffic for the client and purges the data to
426 the network before removing the client entry.
428 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
431 an client is killed from the SILC Network. Updated the protocol
434 Added new function silc_server_send_notify_killed to the
435 silcd/packet_send.[ch].
437 * Added function silc_server_packet_relay_notify to relay notify
438 packets that are destined directly to a client. In this case
439 the server does not process the notify packets but merely relays
440 it to the client. Affected file silcd/packet_send.[ch].
442 Added also silc_server_packet_process_relay_notify to check
443 whereto relay the notify. Affected file is
444 silcd/packet_receive.[ch].
446 * Implemented the KILL command to the server.
450 * Added the backup schema desgined last fall to the protocol
451 specs for everyone to see. The specification is in the
452 *-spec-xx.txt draft and the packet type definitions for the
453 backup routers is in *-pp-xx.txt draft. Thusly, added also
454 new packet type SILC_PACKET_CELL_ROUTERS.
456 * A big security problem in the implementation discovered. The
457 signoff of an client did not cause new channel key generation
458 which it of course should've done. The channel keys must be
459 always re-generated when client leaves (or signoffs) the channel.
460 The silc_server_remove_from_channels funtion now handles
461 the channel key re-generation.
463 * Added `sender' argument to the silc_server_send_notify_on_channels
464 to not to send the client provided as argument. Affected file
465 silcd/packet_send.[ch].
467 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Implemented OPER and SILCOPER commands into the server and
472 * Added silc_auth_verify and silc_auth_verify_data to verify
473 the authentication directly from the authentication payload.
474 It supports verifying both passphrase and public key based
475 authentication. Affected file lib/silccore/silcauth.[ch].
477 * Added `hash' field to the SilcIDListData structure. It is the
478 hash negotiated in the SKE protocol. Affected file is
481 * Slight redesigning of the SilcAuthPayload handling routines.
482 Do not send SilcPKCS but SilcPublicKey as argument.
484 * Implemented the public key authentication support to the
485 serverconfig. The public key is loaded from the provided path
486 and saved as authentication data to void * pointer. Thus,
487 changed the unsigned char *auth_data to void *auth_data;
489 * Fixed SHUTDOWN command to send the reply before the server
490 is shutdown. :) Affected file silcd/command.c.
492 * Fixed fatal bug in CONNECT command. The hostname was invalid
493 memory and server crashed. Affected file silcd/command.c.
495 * Fixed fatal bug in CLOSE command. The server_entry became
496 invalid but was referenced later in the command. Affected file
499 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Fixed fatal bug in failure packet handling. Server ignored
502 the failure and thus crashed when it came.
506 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
509 that the command may be executed only once in (about) 2 seconds.
510 The old SILC_CF_LAG flag is same but allows command bursts up
511 to five before limiting.
513 Added the support for CF_LAG and CF_LAG_STRICT flags to the
514 server code. Various commands now includes the CF_LAG_STRICT
515 flag to disallow any kind of miss-use of the command.
517 * Fixed the silc_buffer_unformat to not to allocate any data
518 if the length of the data is zero. It used to allocate the
519 length + 1. Affected file lib/silcutil/silcbuffmt.c.
521 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Changed the format of AdminConnection configuration section
524 in the server. Added username of the admin to the format.
525 Affected files silcd/serverconfig.[ch].
527 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
528 to return admin configuration data by host, username and/or
531 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Implemented WHOWAS command to the server. Added the functions:
535 silc_server_command_whowas_parse,
536 silc_server_command_whowas_send_reply,
537 silc_server_command_whowas_from_client and
538 silc_server_command_whowas_from_server
540 * Added <Client ID> argument to the WHOWAS command reply. Updated
541 the protocol specs accordingly.
543 * Implemented WHOWAS command and command_reply to the client
546 Implemented the WHOWAS printing on the user interface.
548 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Added new argument to the WHOWAS command reply, the real name.
551 It is an optional argument. Updated the protocol specs.
553 * Added SilcIDCacheDestructor callback that is registered when
554 the SilcIDCache is allocated. The callback is called when
555 an cache entry in the ID Cache expires, or is purged from the
556 cache. Added into lib/silccore/idcache.[ch].
558 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
559 to destruct the client entries when the cache entry expires.
560 Other ID Cache's in server and in the client library ignores
563 * If the ID Cache entry's `expire' field is zero then the entry
564 never expires. Added boolean `expire' argument to the
565 silc_idcache_add function in the lib/silccore/idcache.[ch].
566 If it is TRUE the default expiry value is used.
568 * Added silc_server_free_client_data_timeout that is registered
569 when client disconnects. By default for 5 minutes we preserve
570 the client entry for history - for WHOWAS command.
572 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Added support to the server to enforce that commands are not
575 executed more than once in 2 seconds. If server receives
576 commands from client more frequently, timeout is registered
577 to process the commands. Affected file silcd/command.c.
578 Added new function silc_server_command_process_timeout.
580 * Changed NICK_NOTIFY handling in client library to check that
581 if the client's nickname was changed, so there is no need to
582 resolve anything from the server.
584 * Removed error printing from the WHOIS and IDENTIFY commands.
585 If error occurs then it is ignored silently in the client library.
586 The application, however, may map the received error to
587 human readable error string. The application currently maps
588 the NO_SUCH_NICKNAME error to string.
590 * Made the command status message public to the application. Moved
591 them from lib/silcclient/command_reply.c to
592 lib/silcclient/command_reply.h. The application can map the
593 received command status to the string with the
594 silc_client_command_status_message function.
596 * Added check to the server to check that client's ID is same
597 as the Source ID in the packet the client sent. They must
600 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
602 * Added dist-bzip hook to the Makefile.am to make bzip2
603 compressed distributions.
605 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Server now enforces the maximum length for the nickname and
608 the channel as protocol specification dictates. 128 bytes for
609 nickname and 256 bytes for channel name.
611 * Moved the WHOIS printing to the application. The client libary
612 does not print out the WHOIS information anymore, the application
613 must do it. Renamed silc_client_command_reply_whois_print to
614 the silc_client_command_reply_whois_save.
616 The client's idle time is also sent to the application now, and
617 the idle is shown on screen.
619 * Added silc_client_command_reply_identify_save to save the
620 received IDENTIFY entries.
622 * Do not check for channel private keys in message sending and
623 reception if the channel does not have the PRIVKEY mode set.
624 Affected file lib/silclient/client_channel.c.
626 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
629 just surfaced after chaning the JOIN procedure.
631 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Added silc_client_get_clients_by_list to get client entries
634 from Client ID list, that is returned for example by JOIN
635 and USERS command replies. The application should use this
636 function for example when JOIN command reply is received to
637 resolve the clients already on the channel (library does not
638 do that anymore as USERS command reply is not used in the JOIN
639 procedure anymore). Affected files lib/silcclient/silcapi.h and
640 lib/silcclient/idlist.c.
642 * JOIN command reply and USERS command reply returns now SilcBuffer
643 pointers instead of unsigned char pointers when returning
644 the client list and mode list.
646 * Added <Client ID> argument to the JOIN command reply, mainly
647 for the server to identify for which client the command was
648 originally sent. Updated protocol specs accordingly.
650 * Added SilcDlist private_key pointer to the SilcChannelEntry
651 in the client to support the channel private keys. Affected
652 file is lib/silcclient/idlist.h.
654 * Added SilcChannelPrivateKey argument to the function
655 silc_client_send_channel_message so that application can choose
656 to use specific private ke if it wants to. If it is not provided,
657 the normal channel key is used, unless private keys are set.
658 In this case the first (key that was added first) is used
659 as the encryption key.
661 * Implemented the support for channel private key handling.
662 Implemented the following functions:
664 silc_client_add_channel_private_key,
665 silc_client_del_channel_private_keys,
666 silc_client_del_channel_private_key,
667 silc_client_list_channel_private_keys and
668 silc_client_free_channel_private_keys
670 Affected file lib/silcclient/client_channel.c.
672 * Added the support for the private keys in the channel message
673 sending and encryption and in the message reception and
674 decryption. Affected funtions are
675 silc_client_send_channel_message and silc_client_channel_message.
677 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Added SKE's key verify callback to the client library's
680 KE protocol context. Affected files lib/silcclient/protocol.[ch].
682 * Removed the statement that server (or router) must send USERS
683 command reply when joining to the channel so that the client
684 knows who are on the channel. Instead, the client list and
685 client's mode list is now sent in the JOIN command reply to the
686 client who joined channel. This is better solution.
688 * Added function silc_server_get_users_on_channel and function
689 silc_server_save_users_on_channel to the silcd/server.[ch].
691 * Removed function silc_server_command_send_users from the
694 * Do not show topic on the client library anymore. The topic is
695 sent in the command reply notify to the application and the
696 application must show the topic now.
698 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Added client searching by nickname hash into the IDENTIFY and
701 WHOIS commands in the server as they were clearly missing from
702 them. Affected file is silcd/command.c.
704 * Fixed a bug in private message receiving in the client library.
705 The remote ID was freed and it wasn't supposed, now it is
708 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
710 * Minor fix to the channel payload; allocate the data area, as it
711 needs to be of specific length.
713 * If the key agreement port is zero then the operating
714 system will define the bound port. Affected files are
715 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
717 * Added new function silc_channel_payload_decrypt into the file
718 lib/silccore/silcchannel.[ch].
720 * Moved the channel message etc, check from silc_packet_decrypt
721 to applications. The library calls now a generic
722 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
723 when the packet is either normal or special. This was done to
724 allow more wide range of checking that was not allowed when
725 the code was in library. Now applications can do virtually any
726 checks to the packet and return to the library the decision how
727 the packet should be processed. Affected files are
728 lib/silccore/silcpacket.[ch].
730 Added silc_server_packet_decrypt_check to the server and
731 silc_client_packet_decrypt_check to the client library.
733 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
734 to send with specified source and destination information.
736 * Channel message delivery between routers was broken after the
737 channel key distribution was fixed earlier. The channel key
738 was used be to distributed to other routers as well which is not
739 allowed by the protocol. Now this is fixed and channel keys
740 really are cell specific and the channel message delivery between
741 routers comply with the protocol specification.
743 * Fixed various commands in server to check also the global list
744 for the channel entry and not just the local list. The affected
745 file silcd/command.c.
747 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added assert()s to buffer formatting and unformatting routines
750 to assert (if --enable-debug) when error occurs. Affected
751 file: lib/silcutil/silcbuffmt.c.
753 * Changed to auto-reconnect to check whether the remote host is
754 router and register the re-connect timeout if it is. It used
755 to check that whether we are normal server, but router must do
756 auto-reconnect with another router as well. Affected file
759 * Removed the [<key len>] option from CMODE command as the cipher
760 name decides the key length, nowadays. See the defined ciphers
761 from the protocol specification.
763 * Added [<hmac>] option to the CMODE command to define the HMAC
764 for the channel. Added SILC_CMODE_HMAC channel mode.
766 * Added [<hmac>] option for the JOIN command so that user can
767 select which HMAC is used to compute the MACs of the channel
770 * Added Hmac field to the Channel Message Payload. The integrity
771 of plaintext channel messages are now protected by computing
772 MAC of the message and attaching the MAC to the payload. The
773 MAC is encrypted. Now, it is clear that this causes some
774 overhead to the size of the packet but rationale for this is that
775 now the receiver can verify whether the channel message decrypted
776 correctly and also when private keys are set for the channel the
777 receiver can decrypt the packet with several keys and check from
778 the MAC which key decrypted the message correctly.
780 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
781 lib/silccrypt/silccipher.[ch].
783 * Added silc_hash_len to return the digest length into the
784 lib/silcrypt/silchash.[ch].
786 * Rewrote parts of Silc Channel Payload interface in the
787 lib/silccore/silcchannel.[ch]. The encode function now also
788 encrypts the packet and parse function decrypts it.
790 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Fixed a minor formatting bug in the SKE's key material processing.
793 It actually might have processed the keys wrong way resulting
796 * Redefined the mandatory HMAC algorithms and added new algorithms.
797 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
798 and hmac-md5 truncated to 96 bits. The mandatory is now
799 hmac-sha1-96. Rest are optional (including the one that used
800 to be mandatory). Rationale for this is that the truncated HMAC
801 length is sufficient from security point of view and can actually
802 make the attack against the HMAC harder. Also, the truncated
803 HMAC causes less overhead to the packets. See the RFC2104 for
806 * Added new [hmac] configuration section. The SKE used to use
807 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
808 is of course wrong. The official names that must be proposed in
809 the SKE are the ones defined in the protocol specification
810 (hmac-sha1-96 for example). The user can configure any hmac
811 using any hash function configured in the [hash] section. At
812 least, the mandatory must be configured.
814 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
816 * Added HMAC list to the SKE proposal list. It has now both
817 hash algorithm list and HMAC list. This makes the protocol
818 incompatible with previous versions. The SKE now seems to work
819 the way it is supposed to work, for the first time actually.
821 * Defined plain Hash algorithms to the protocol specification.
824 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Implemented support for key agreement packets into the server.
827 Added functions silc_server_key_agreement and
828 silc_server_send_key_agreement. Other than these functions,
829 server has nothing to do with this packet.
831 * Added support for private message key packets into the server.
832 Added functions silc_server_private_message_key and
833 silc_server_send_private_message_key.
837 * Changed the silc_[client|server]_protocol_ke_set_keys to be
838 called in the protocol's final callback instead in the END
839 protocol state. This makes a little more sense and in the same
840 time in client we can use the same protocol routines for normal
841 key exchange and to key agreement packet handling as well.
843 * Added to both client's and server's KE protocol context the
844 SilcSKEKeyMaterial pointer to save the key material. We will
845 bring the key material to the protocol's final callback by doing
846 this. The final callback must free the key material.
848 * Added SKE's packet_send callback into client's KE protocol
849 context so that the caller can choose what packet sending function
850 is used. This way we can use different packet sending when
851 doing normal SKE when doing key agreement packet handling (in
852 the key agreement packet handling we do not want to encrypt
855 * Implemented the responder side of the key agreement routines
856 in the client. The client can now bind to specified port and
857 accept incoming key negotiation. The key material is passed
858 to the application after the protocol is over.
860 * Implemented the processing of incoming Key Agreement packet
861 in the client. Added function silc_client_key_agreement to
864 * Implemented the intiator side of the key agreement routines
865 in the client. The client can now initiate key agreement with
866 another remote client. The key material is passed to the
867 application after the protocol is over.
869 * Created client_keyagr.c to include all the key agreement
872 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
873 SILC_TASK_CALLBACK except that it is not static.
875 * Created client_notify.c and moved the Notify packet handling
876 from the client.[ch] into that file.
878 * Created client_prvmsg.c and moved all private message and
879 private message key routines from the client.[ch] into that file.
881 * Create client_channel.c and moved all channel message and
882 channel private key routines from the client.[ch] into that file.
884 * Changed silc_client_get_client_by_id_resolve to resolve with
885 WHOIS command instead of IDENTIFY command, in the file
886 lib/silclient/idlist.c.
888 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Implemented the SKE's responder side to the Client library.
892 * When FAILURE is received to the protocol do not trust it
893 blindly. Register a timeout to wait whether the remote closes
894 the connection as it should do it, only after that process the
895 actual failure. This was changed to both client and server.
897 * Added client_internal.h to include some of the structures
898 there instead of client.h in lib/silcclient/.
900 * Added function silc_task_unregister_by_callback to unregister
901 timeouts by the callback function.
903 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Some "Incomplete WHOIS info" errors has been appearing on the
906 log files. Took away the entry->userinfo check from WHOIS
907 reply sending. The entry->userinfo is now " " if client did not
908 provide one. I thought this was fixed earlier but something
909 is wrong still. Let's see if the error still appears.
911 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
913 * Fixed a minor bug in the login when the channel key is
914 re-generated in the server. It used to generate the key in
915 wrong order and thus caused problems in the channel traffic.
917 * Fixed a minor bug in channel key distsribution after
918 KICK command. The key was not sent to the router even though
921 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Added silc_ske_process_key_material_data as generic routine
924 to process any key material as the SILC protocol dictates. The
925 function is used by the actual SKE library but can be used by
926 applications as well. This relates to the private message keys
927 and the channel private keys since they must be processed the
928 same way the normal SILC session keys. The protocol dictates
929 this. Affected files: lib/silcske/silcske.[ch].
931 Added also silc_ske_free_key_material to free the
932 SilcSKEKeyMaterial structure.
934 * Defined silc_cipher_set_key function to set the key for
935 cipher without using the object's method function. The affected
936 files: lib/silccrypt/silccipher.[ch].
938 * Implemented silc silc_client_add_private_message_key,
939 silc_client_add_private_message_key_ske,
940 silc_client_del_private_message_key,
941 silc_client_list_private_message_keys and
942 silc_client_free_private_message_keys functions in the
945 Added functions silc_client_send_private_message_key to send
946 the Private Message Key payload and silc_client_private_message_key
947 to handle incoming Private Message Key payload.
949 * Added Cipher field to the Private Message Key payload to set
950 the cipher to be used. If ignored, the default cipher defined
951 in the SILC protocol (aes-256-cbc) is used.
953 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Removed lib/silcclient/ops.h file.
957 Redefined parts of the SILC Client Library API. Created new
958 file silcapi.h that deprecates the ops.h file and defines the
959 published Client Library API. Defined also private message key
960 API and channel private key API into the file.
962 This is the file that the application must include from the
963 SILC Client Library. Other files need not be included by
964 the application anymore.
966 * Added new key_agreement client operation callback and also
967 defined the Key Agreement library API for the application.
969 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
972 is used by clients to request key negotiation between another
973 client in the SILC network. If the negotiation is started it
974 is performed using the SKE protocol. The result of the
975 negotiation, the secret key material, can be used for example
976 as private message key.
978 Implemented the Key Agreement payload into the files
979 lib/silccore/silauth.[ch].
981 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Redefined ciphers for the SILC protocol. Added some new ciphers
984 and defined the key lengths for the algorithms. Changed the
985 code accordingly. The default key length is now 256 bits.
987 * Fixed SKE key distribution function silc_ske_process_key_material
988 when the key length is more than 128 bits. The default key
989 length in SILC is now 256 bits.
991 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
992 to indicate unsupported algorithm.
994 * Renamed rijndael.c to aes.c and all functions as well.
996 * Fixed a long standing channel key setting bug in client library.
997 Weird that it has never surfaced before.
999 * Fixed bug in channel deletion. If the entire channel is removed
1000 then it must also delete the references of the channel entry
1001 from the client's channel list as the client's channel entry and
1002 the channel's client entry share same memory.
1004 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Implemented CONNECT and SHUTDOWN commands in the client.
1008 * Implemented CLOSE command to the client.
1010 * Added the function silc_idlist_find_server_by_name into the
1011 files silcd/idlist.[ch].
1013 Added the function silc_idlist_find_server_by_conn into the
1014 files silcd/idlist.[ch].
1016 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * DIE command was renamed to SHUTDOWN. Updated the both code
1021 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1022 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1024 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1027 * Added function silc_server_create_connection function to create
1028 connection to remote router. My server implementation actually
1029 does not allow router to connect to normal server (it expects
1030 that normal server always initiates the connection to the router)
1031 so the CONNECT command is only good for connecting to another
1034 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1037 or some other client was kicked from the channel.
1039 Implemented the handling of the notify type to both client
1042 Implemented silc_server_send_notify_kicked to send the KICKED
1043 notify. It is used to send it to the server's primary router.
1045 * Implemented the KICK command into server and client.
1047 * Added `query' argument to the silc_idlist_get_client function
1048 to indicate whether to query the client from server or not if
1051 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1052 to indicate that the client is not channel founder.
1056 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Removed the rng context from SilcPacketContext structure and
1059 changed that the packet routine uses the Global RNG API.
1061 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Added support for quit message that client can "leave" on the
1064 channel when it quits the SILC. It is ditributed inside the
1065 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1067 Added silc_server_free_client_data that will take the
1068 signoff message as argument.
1070 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1072 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Updated parts of the protocol specification to keep it up
1077 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1080 payloads in one packet.
1082 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1083 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1084 use now the new List flag.
1086 * Also deprecated the following packet types: REPLACE_ID,
1087 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1089 * Added list support for Notify packet in server.
1091 * Added silc_server_send_notify_channel_change to send the
1092 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1093 the silc_server_send_replace_id.
1095 * Added silc_server_send_notify_nick_change to send the
1096 NICK_CHANGE notify type. Deprecates the function
1097 silc_server_send_replace_id.
1099 * Added silc_server_send_notify_join to send the JOIN notify type.
1100 Deprecates the function silc_server_send_new_channel_user.
1102 * Added silc_server_send_notify_leave to send LEAVE notify type.
1103 Deprecates the function silc_server_send_remove_channel_user.
1105 * Added silc_server_send_notify_cmode and
1106 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1107 types. Deprecates the silc_server_send_set_mode function.
1109 * Added SERVER_SIGNOFF notify type to indicate that server has
1110 quit. This means that all clients on the channel from that
1111 server will drop. This can be also used when netsplit happens.
1113 Deprecated REMOVE_ID packet type since it is not needed anymore
1116 Added silc_server_send_notify_server_signoff to send the
1117 SERVER_SIGNOFF notify type. Deprecates the function
1118 silc_server_send_remove_id.
1120 Added also silc_server_send_notify_signoff to send the
1121 SIGNOFF notify type.
1123 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1124 SILC protocol from this day on. Changed the protocol
1125 specification as well.
1127 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1128 notify type. It is used between routers to notify about
1129 topic changes on a channel.
1131 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1134 * Partly updated the protocol specification to comply with the
1135 changes now made. It is still though a bit outdated.
1137 * The JOIN notify type now takes one extra argument <Channel ID>.
1138 The packet used to be destined to the channel but now the
1139 JOIN type may be sent as list thus it is impossible to
1140 destine it to any specific channel. By adding this argument
1141 it is again possible.
1143 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Added CREDITS file. The CHANGES and CREDITS file will appear
1146 in the distribution as well.
1148 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1151 types in the server's silcd/packet_receive.c.
1153 * Implemented CMODE and CUMODE to work in router environment.
1155 * Fixed minor encoding and decoding buglet from the
1156 lib/silccore/silcmode.c.
1158 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1161 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1163 * Changed all SilcConfigServer* and silc_config_server* to
1164 SilcServerConfig* and silc_server_config*, respectively.
1167 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Associated the ID (client or server ID) to the Authentication
1170 Payload to avoid any possibility of forging. Updated the
1171 protocol specification and the code accordingly.
1173 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * The RSA key length is now save to the RsaKey context in the
1176 key generation process in lib/silccrypt/rsa.c. The key length
1177 is now used to figure out the maximum size of the block allowed
1178 to be encrypted/signed.
1180 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1181 is equivalent to the silc_mp_mp2bin but does not allocate any
1184 * Changed silc_mp_mp2bin API to take length argument. If it is
1185 non-zero then the buffer is allocated that large. If zero, then
1186 the size is approximated using silc_mp_sizeinbase, which however
1189 * Created Global RNG API which is global RNG that application can
1190 initialize. After initializing, any routine anywhere in the
1191 code (including library) can use RNG without allocating a new
1192 RNG object. This was done to allow this sort of use of the
1193 RNG in code that has no chance to allocate RNG object. All
1194 applications currently allocate this and many routines in the
1195 library use this. Affected file lib/silccrypt/silcrng.[ch].
1197 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1198 it to use the Global RNG API.
1200 * Defined Authentication Payload into protocol specification that
1201 is used during SILC session to authenticate entities. It is
1202 used for example by client to authenticate itself to the server
1203 to obtain server operator privileges.
1205 Implemented this payload into the lib/silccore/silcauth.[ch].
1206 Implemented also routines for public key based authentication
1207 as the new protocol specification dictates.
1209 Moved definitions of different authentication methods from
1210 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1212 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1213 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1214 silc_pkcs_verify_with_hash functions into the file
1215 lib/silccrypt/silcpkcs.[ch].
1217 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * The client entry's userinfo pointer must be always valid.
1220 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1221 will fail since it requires the userinfo. Now, the userinfo
1222 is allocated as "" if actual userinfo does not exist. Actually,
1223 it must exist and it is totally Ok to drop client connections
1224 that does not announce the userinfo. However, we will make
1225 this workaround for now.
1227 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1228 to return the remote port by socket.
1230 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1233 SILC_SERVER_PENDING_EXEC and added an new macro
1234 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1235 data or when error occurs while processing the pending command.
1237 Added new argument `destructor' into silc_server_command_pending
1238 and to the SilcServerCommandPending object. This destructor is
1239 now called after calling the pending callback or if error occurs
1240 immediately. If error occurs the actual pending callback won't
1241 be called at all - only the destructor. The destructor may be
1242 NULL if destructor is not needed.
1244 All this applies for client library code as well. Similar
1245 changes were made there as well for the pending commands.
1247 In the client, the application must now allocate the
1248 SilcClientCommandContext with the silc_client_command_alloc
1251 * Added reference counter to the SilcServerCommandContext. Added
1252 function silc_server_command_alloc and silc_server_command_dup
1255 Same type of functions added to the client library for the same
1258 * Removed the cmd_ident from IDListData away since it is now
1259 global for all connections. It is the command identifier used
1260 in command sending and with pending commands. The affected file
1263 * Added reference counter to the SilcSocketConnection objecet to
1264 indicate the usage count of the object. The object won't be
1265 freed untill the reference counter hits zero. Currently only
1266 server uses this, and client ignores it. The client must be
1267 set to use this too later. The affected files are
1268 lib/silccore/silcsockconn.[ch]. Added also the function
1269 silc_socket_dup to increase the reference counter.
1271 This was mainly added because it is possible that the socket
1272 is removed underneath of pending command or other async
1273 operation. Now it won't be free'd and proper DISCONNECTING
1274 flags, etc. can be set to avoid sending data to connection that
1275 is not valid anymore.
1277 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1278 the connection. After that it sets SILC_SET_DISCONNECTED.
1279 It is, however, possible that the socket data is not still freed.
1280 The silc_server_packet_process now checks that data is not
1281 read or written to connection that is DISCONNECTED. The socket
1282 get's freed when the reference counter hits zero.
1284 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Changed the client operation API: channel_message operation's
1287 `sender' is now the client entry of the sender, not the nickname
1288 and the `channel' is the channel entry, not the channel name.
1290 In the private_message operation the `sender' is now also the
1291 client entry of the sender not the nickname.
1293 Affected file is lib/silcclient/ops.h and all applications
1294 using the client operations.
1296 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Moved the calling of ops->connect() from connect_to_server_final
1299 into receive_new_id functin since that is the point when the
1300 client is actually allowed to send traffic to network. The
1301 affected file is lib/silcclient/client.c.
1303 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1306 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1307 (if needs broadcasting) instead of broadcasting the packets one
1308 by one which would make a burst in the network traffic.
1310 * Added `broadcast' argument to the functions in silcd/server.[ch]
1311 silc_server_create_new_channel[_with_id] to indicate whether
1312 to send New Channel packet to primary router.
1314 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Added new function into the silcd/server.[ch] files:
1317 silc_server_create_new_channel_with_id to create new channel with
1318 already existing Channel ID.
1320 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1321 lib/silccore/silcpacket.h. This packet is used t send list of
1322 Set Mode payloads inside one packet. Server uses this to set
1323 the modes for the channels and clients on those channels, that it
1324 announced to the router when it connected to it. The protocol
1325 specification has been updated accordingly.
1327 * The silc_server_new_channel did not handle the packet coming
1328 from normal server as it normally does not send that. However,
1329 when it announces its channels it does send it. Implemented
1330 the support for that.
1332 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1333 into the file lib/silccore/id.h.
1335 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Fixed memory leaks in the functions silc_idlist_del_client,
1338 silc_idlist_del_channel and silc_idlist_del_server in the file
1339 silcd/idlist.c. All of those leaked like a sieve.
1341 * Fixed some small memory leaks in the client's function
1342 silc_client_notify_by_server.
1344 * Added functions into silcd/server.c: silc_server_announce_clients,
1345 silc_server_announce_channels and silc_server_announce_server.
1346 These functions are used by normal and router server to announce
1347 to its primary router about clients, channels and servers (when
1348 router) that we own. This is done after we've connected to the
1351 These functions effectively implements the following packet types:
1352 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1353 and SILC_PACKET_NEW_ID_LIST.
1355 * Added new functions into the silcd/packet_receive.[ch]:
1356 silc_server_new_id_list, silc_server_new_channel_list and
1357 silc_server_new_channel_user_list to handle the incoming
1358 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1360 * Added support of changing Channel ID in the function
1361 silc_server_replace_id. If the server that announces a channel
1362 to the router already exists in the router (with same name but
1363 with different Channel ID), router is responsible to send
1364 Replace ID packet to the server and force the server to change
1365 the Channel ID to the one router has.
1367 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1368 client that the Channel ID has been changed by the router. The
1369 normal server sends this to the client. Client must start using
1370 the new Channel ID as the channel's ID.
1372 Implemented handling of this new type into lib/silcclient/client.c
1373 into the function silc_client_notify_by_server.
1375 * Added new function silc_idlist_replace_channel_id into the files
1376 silcd/idlist.[ch] to replace the Channel ID.
1378 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Call silc_server_command_identify_check always when processing
1381 the IDENTIFY command in silcd/command.c
1383 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1386 send keepalive packets. The packet can be sent by clients,
1387 servers and routers.
1389 Added function silc_socket_set_heartbeat into the file
1390 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1391 If not set, the heartbeat is not performed. The actual
1392 heartbeat is implemented in the low level socket connection
1393 library. However, application is responsible of actually
1396 Added silc_server_send_heartbeat to send the actual heartbeat
1397 packet into silcd/packet_send.[ch]. Server now performs
1398 keepalive with all connections.
1400 * Added silc_task_get_first function into lib/silcutil/silctask.c
1401 to return the timeout task with shortest timeout. There was a bug
1402 in task unregistration that caused problems. TODO has been
1403 updated to include that task system must be rewritten.
1405 * The client library will now resolve the client information when
1406 receiving JOIN notify from server for client that we know but
1407 have incomplete information.
1409 * Rewrote parts of silc_server_remove_from_channels and
1410 silc_server_remove_from_one_channel as they did not remove the
1411 channel in some circumstances even though they should've.
1413 * Encryption problem encountered in server:
1415 The LEAVE command used to send the Channel Key packet to the
1416 router immediately after generating it. However, the code
1417 had earlier sent Remove Channel user packet but not immediately,
1418 ie. it was put to queue. The order of packets in the router
1419 was that Channel Key packet was first and Remove Channel User
1420 packet was second, even though they were encrypted in the
1421 reverse order. For this reason, MAC check failed. Now, this
1422 is fixed by not sending the Channel Key packet immediately but
1423 putting it to queue. However, this is more fundamental problem:
1424 packets that are in queue should actually not be encrypted
1425 because packets that are sent immediately gets encrypted
1426 actually with wrong IV (and thus MAC check fails). So, packets
1427 that are in queue should be encrypted when they are sent to
1428 the wire and not when they put to the queue.
1430 However, the problem is that the current system has not been
1431 designed to work that way. Instead, the packet is encrypted
1432 as soon as possible and left to the queue. The queue is then
1433 just purged into wire. There won't be any fixes for this
1434 any time soon. So, the current semantic for packet sending
1437 o If you send packet to remote host and do not force the send
1438 (the packet will be in queue) then all subsequent packets to the
1439 same remote host must also be put to the queue. Only after the
1440 queue has been purged is it safe again to force the packet
1443 o If you send all packets immediately then it safe to send
1444 any of subsequent packets through the queue, however, after
1445 the first packet is put to queue then any subsequent packets
1446 must also be put to the queue.
1448 Follow these rules and everything works fine.
1450 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1452 * Added new function silc_server_remove_clients_by_server to
1453 remove all client entries from ID list when the server connection
1454 is lost. In this case it is also important to invalidate all
1455 client entires as they hold the invalid server entry. This
1456 fixes fatal bug when server has lost connection and will reconnect
1459 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Made some sanity checks to silc_server_daemonise like to check
1462 whether the requested user and group actually exists.
1464 * Added sanity check to SKE's silc_ske_responder_finish to check
1465 that the public and private key actually is valid.
1467 * Invalidate the client's nickname when receiving Replace ID
1468 packet and the Client ID is being replaced. This means that the
1469 server will query the nickname if someone needs it (client)
1472 * Sort the ID Cache in client library when the ID Cache data
1473 has changed (needs sorting).
1475 * Do not allow for SILC client to create several connections to
1476 several servers. The client does not support windows right now
1477 and generating multiple connections causes weird behaviour.
1479 Irssi-silc client does support windows and can handle several
1480 connections without problems, see: www.irssi.org and SILC plugin.
1482 * Fixed some places where client was added to the IDList. The
1483 rule of thumb is following (in order to get everything right):
1484 If the client is directly connected local client then the
1485 `connection' argument must be set and `router' argument must be
1486 NULL to silc_idlist_add_client function. If the client is not
1487 directly connected client then the `router' argument must
1488 bet set and the `connection' argument must be NULL to the
1489 silc_idlist_add_client function.
1491 * The funtion silc_server_packet_send_local_channel actually did
1492 not check whether the client was locally connected or not. It
1493 does that now. Fixed a bug related to LEAVE command.
1495 * Fixed Remove Channel User payload parsing bug in server's
1496 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1498 * The server's silc_server_save_channel_key now checks also the
1499 global ID list for the channel as it might not be in the local
1500 list. Fixed a bug related to LEAVE command.
1502 * Is this the end of the [<unknown>] buglet that has been lurking
1503 around for a long time? A little for loop fix in server's
1504 silc_server_command_whois_parse that is used by both IDENTIFY
1505 and WHOIS command. At least, this was a clear bug and a cause
1506 of one type of [<unknown>] buglet.
1508 * WHOIS and IDENTIFY commands call the function
1509 silc_server_command_[whois/identify]_check function even if
1510 we are not router server.
1512 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1514 * Added --with-gmp configuration option. If set the GMP
1515 is always compiled in the SILC source tree. If not set then
1516 it is checked whether the system has the GMP3 installed. If
1517 it has then the GMP won't be compiled (the system's headers
1518 and library is used), if it doesn't have it then the GMP is
1519 compiled in the SILC source tree.
1521 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Changed RSA private exponent generation to what PKCS #1
1524 suggests. We try to find the smallest possible d by doing
1525 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1526 not security fix but optimization.
1528 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Added new config entry [Identity] to fork the server and run
1531 it as specific user and group. A patch from Bostik.
1533 * Imported Dotconf configuration library into lib/dotconf.
1534 This will be used to create the SILC configuration files later.
1535 It will appear in the distsribution after this commit.
1537 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1539 * A big code auditing weekend happening. Auditing code for
1540 obvious mistakes, bugs and errors. Also, removing any code
1543 Removed files for being obsolete:
1545 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1546 inline in the file lib/silcutil/silcbuffer.h)
1548 o lib/silcutil/silcbufutil.c (the header has inline versions)
1550 Changed code to fix possible error conditions:
1552 o The buffer formatting routines now check that the destination
1553 buffer really has enough space to add the data. This applies for
1554 both buffer formatting and unformatting
1555 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1556 unformatting was changed to accomodate following rules:
1557 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1558 sent to the function while XXX_*STRING will not allocate or copy
1559 the data into the buffer. Instead it sets the pointer from the
1560 buffer into the pointer sent as argument (XXX_*STRING used to
1561 require that the pointer must be allocated already). This change
1562 makes this whole thing a bit more consistent and more optimized
1563 (note that the data returned in the unformatting with XXX_*STRING
1564 must not be freed now). The routines return now -1 on error.
1566 o Tried to find all code that use buffer_format and buffer_unformat
1567 and added return value checking to prevent formatting and
1568 especially unformatting errors and possible subsequent fatal
1571 o Changed ske->x and ske->KEY to mallocated pointers in
1572 lib/silcske/silcske.h. Fixed possible data and memory leak.
1574 o Added return value checking to all *_parse* functions. Fixed
1575 many memory leaks as well.
1577 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1578 so that buffer overflows would not happen. All code now also
1579 checks the return value as it can fail.
1581 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Added reconnection support to server if the normal server looses
1584 its connection to the router (for example if router is rebooted).
1585 The server performs normal reconnection strategy implemented
1586 to the server. Affected file silcd/server.c.
1588 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Added new packet type SILC_PACKET_SET_MODE that is used to
1591 distribute the information about changed modes (for clients,
1592 channels and clients channel modes) to all routers in the
1593 network. Updated the protocol specification accordingly.
1595 Added functions into silcd/packet_send.c and
1596 silcd/packet_receive.c: silc_server_send_set_mode,
1597 silc_server_set_mode.
1599 Added new files silcmode.[ch] into lib/silccore that implements
1600 the encoding and decoding of Set Mode Payload. Added new type
1601 SilcSetModePayload. Moved the definitions of different modes
1602 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1604 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Oops, a little mistake in server's connection authentication
1607 protocol. The protocol is not ended with FAILURE but with
1608 SUCCESS if the authentication is Ok. :) Affected file is
1611 * Implemented NICK_CHANGE notify handling in server in the file
1612 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1613 the local clients on the channel. After the changing nickname
1614 in router environment snhould work and the [<unknown>] nickname
1615 should appear no more.
1617 The silc_server_replace_id function that receives the Replace ID
1618 payload now sends the NICK_CHANGE notify type also in the file
1619 silcd/packet_receive.c
1621 * Changed WHOIS and IDENTIFY command to support the maximum amount
1622 of arguments defined in protocol specs (3328 arguments). This
1623 fixed a bug that caused problems when there were more than three
1626 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added extra parameter, command identifier, to the
1629 silc_client_send_command so that explicit command identifier
1632 Changed that ID list routines uses specific command identifier
1633 when sending WHOIS/IDENTIFY requests to the server so that they
1634 can be identified when the reply comes back.
1636 Affected files lib/silcclient/command.[ch],
1637 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1639 * Added `sender' argument to silc_server_packet_send_to_channel
1640 to indicaet the sender who originally sent the packet to us
1641 that we are now re-sending. Ignored if NULL. Affected file
1642 silcd/packet_send.[ch].
1644 * Added some server statistics support in silcd/server_internal.h
1645 SilcServerStatistics structure and around the server code. Also
1646 send some nice statistics information when client is connecting
1649 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Fixed channel ID decoding in server's JOIN command reply in
1652 silcd/command_reply.c
1654 * Fixed braodcasting of replace ID payload to not to send it if
1655 we are standalone server in silcd/packet_receive.c.
1657 * Fixed all channel message sending routines to not to send
1658 packets to clients that has router set, since they are routed
1659 separately in the same function earlier. Affects file
1660 silcd/packet_send.c and all channel packet sending functions.
1662 * In USERS reply, res_argv[i] are not allocated, the table
1663 is allocated. Thus changed that free the table, not its
1666 * In server's whois_check and identify_check if the client is
1667 locally connected do not send any WHOIS commands - they are not
1670 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Fixed some minor bugs in client when sending WHOIS command. The
1673 arguments was in wrong order.
1675 * Removed statis function add_to_channel from server in
1676 silcd/command.c that was previously used with the joining but
1679 * Tested USERS command in router environment successfully with two
1680 routers, two servers and two clients.
1682 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Reorganized the USERS command and command reply in client library
1685 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1686 When the command is given by user we register a pending command
1687 callback that will reprocess the command after the reply has been
1688 received from the server. When reprocessing the packet we then
1689 display the information. Thus, the USERS information is displayed
1690 now in the command callback instead of in the command reply
1691 callback. The processing of the command is same as previously
1692 when server has sent the command reply in the JOINing process.
1694 * Added to USERS command in silcd/command_reply.c to join the client,
1695 we didn't use to know about, to the channel after we've created
1696 a client entry for it. Also, for clienet we did know already still
1697 check whether it is on the channel or not and add it if not.
1699 * Removed silc_server_command_join_notify as the function and its
1702 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Changed the client's pending command handling to the same as the
1705 server's pending command handling. It is also now possible to
1706 execute command reply functions from other command reply
1707 function as the function callbacks for commands and command
1708 replies are one and same. The pending commands are not static
1709 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1710 in client connection context. Thus, pending commands are server
1711 connection specific as it is convenient.
1713 Changed the function silc_client_command_pending and
1714 silc_client_command_pending_del and added new function
1715 silc_client_command_pending_check. Removed the
1716 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1719 * Added cmd_ident, current command identifier, to the client
1720 connection context in lib/silcclient/client.h to keep track on
1721 command identifiers used in command sending. Client's command reply
1722 function handling now supports the mandatory command identifiers.
1724 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1725 funtions in client to fully support pending command callbacks.
1727 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1728 as one of the arguments to the application in the command reply
1731 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1732 before first releasing SILC but came back. Now it is removed again
1733 and should come back nomore. The FORWARDED flag was used only
1734 by the JOINing procedure by forwarding the command packet to router.
1735 Now, the JOINing procedure has been changed to more generic (due
1736 to various router environment issues) and FORWARDED is not needed
1737 anymore for anything. The protocol specification is yet to be
1740 Now, removed silc_server_packet_forward from server and the flag
1741 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1743 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Renamed NAMES command to USERS command. The NAMES was named that
1746 due to historical reasons. Now it is renamed. Also, rewrote
1747 parts of the USERS command. The nickname list is not sent anymore
1748 by the server. Only Client ID and mode lists are sent in the USERS
1749 command. Changed this also to the protocol specification.
1751 The client now resolves the names and stuff after it receives
1752 the USERS list from the server when joining to the channel.
1754 * WHOIS and IDENTIFY commands has been changed to support multiple
1755 Client ID's per command. One can now search for multiple users
1756 in the network by sending only one WHOIS or IDENTIFY command.
1757 Changed the code and the protocol specifications.
1759 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1760 uses silc_server_command_whois_parse to parse the request. */
1762 * If normal server, do not parse the WHOIS and IDENTIFY requests
1763 before sending it to the router. Saves some time.
1765 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Fixed JOIN command on client library. Wrong number of arguments
1768 used to crash the client.
1770 * Added silc_server_channel_has_global function to check whether
1771 channel has global users or not.
1773 * Added silc_server_channel_has_local function to check whether channel
1774 has locally connected clients on the channel.
1776 * The silc_server_remove_from_one_channel now checks whether the
1777 channel has global users or not after given client was removed from
1778 the channel. It also checks whether the channel has local clients
1779 on the channel anymore. If it does not have then the channel entry
1780 is removed as it is not needed anymore.
1782 * The silc_server_notify now checks on JOIN notify whether the joining
1783 client is one of locally connected or global. If it is global then
1784 the channel has now global users on the channel and that is marked
1785 to the channel entry. Also, it now saves the global client to
1786 global list who is joining and JOINs it to the channel. This is
1787 for normal server, that is.
1789 Changed silc_server_send_notify_on_channel,
1790 silc_server_packet_relay_to_channel and
1791 silc_server_packet_send_to_channel check if we are normal server
1792 and client has router set (ie. global client) do not send the
1793 message to that client, as it is already routed to our router.
1795 * Implemented LEAVE notify type handling in silc_server_notify
1798 * Tested LEAVE command in router environment successfully. Tested
1799 with two routers, two servers and two clients.
1803 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1805 * Implemented SIGNOFF notify type handling in silc_server_notify
1808 * silc_server_remove_id now removes the client entry from all channels
1809 it has joined and thusly sends SIGNOFF notify type.
1811 * Rewrote the NAMES list generation in server by removing two excess
1812 loops. The lists are created now inside one loop.
1814 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * silc_server_remove_channel_user checks now also global list
1817 for channel and client.
1819 * silc_server_new_channel_user checks now both local and global
1820 list for channel and client. Fixed a bug in client id decoding.
1821 Used to decode wrong buffer.
1823 * silc_server_channel_message checks now both local and global
1824 list for channel entry.
1826 * Tested channel joining (hence JOIN) in router environment
1827 successfully. Tested with two routers, two servers and two
1830 * Tested channel message sending in router environment successfully.
1832 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Added silc_server_save_channel_key into server.[ch] to save the
1835 received channel key in Channel Key payload processing. It is
1836 also used in JOIN command reply handling.
1838 Equivalent function silc_client_save_channel_key added into
1839 client.[ch] into client library.
1841 * Changed JOIN command reply to send information whether the channel
1842 was created or not (is existing already) and the channel key
1843 payload. Changed protocol specs accordingly.
1845 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1846 the request was sent by ID and not by nickname. Crashed on
1849 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1852 now correctly save the received data.
1854 * silc_server_free_sock_user_data now notifies routers in the
1855 network about entities leaving the network.
1857 At the same time implemented functions silc_server_remove_id
1858 and silc_server_send_remove_id to receive and send REMOVE_ID
1859 packets. The packet is used to notify routers in the network
1860 about leaving entities. The ID removed will become invalid in
1863 * Added function silc_idlist_del_server into server. Removes and
1864 free's server entry from ID list.
1866 * silc_server_private_message function now checks, if we are router,
1867 that the destination ID really is valid ID, naturally.
1869 * In router when NEW_ID packet is received (for new client) the
1870 hash of the Client ID is saved in the ID Cache but the
1871 client->nickname is set to NULL, instead of putting the hash
1874 IDENTIFY command now also checks that client->nickname must be
1875 valid. If it is not if will request the data from the server who
1876 owns the client. Added new function
1877 silc_server_command_identify_check.
1879 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1880 to set the command to already allocated Command Payload.
1882 * Tested private message sending in router environment with two
1883 routers, two servers and two clients. Fixed minor bugs and now
1886 * Fixed segfault from client's NAMES command. Used to crash if
1889 * Forwarded packets must not be routed even if it is not destined
1890 to the receiver. Changed server code comply with this.
1892 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Added `require_reverse_mapping' boolean value to ServerParams
1895 structure. If TRUE (not default) the server will require that
1896 the connecting host has fully qualified domain name.
1898 If the reverse mapping is not required and hostname could not be
1899 found the IP address is used as hostname.
1901 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Implemented version string checking to both client and server.
1904 The check is incomplete currently due to the abnormal version
1905 strings used in development version of SILC.
1907 * Changed all command functions in server to use the new
1910 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Changed char *data to unsigned char *data in ID Cache system to
1913 support binary data as ID Cache data. Changed code to support
1914 binary data in lib/silccore/idcache.c.
1916 * Renamed silc_server_packet_relay_command_reply to
1917 silc_server_command_reply as it is normal packet receiving
1918 function. Rewrote the function to accept command replys for
1919 servers and not only for clients.
1921 * Mark remote router always as registered server if we are connecting
1922 to it. Otherwise, commands sent by the router to us are ignored.
1924 * All ID List find routines now returns the ID Cache Entry pointer
1925 as well if requested.
1927 * WHOIS command works now in router environment, tested with two
1928 routers, two servers and two clients.
1930 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1931 in router environment (as it is almost equivalent to WHOIS) but
1932 hasn't been tested thoroughly. Added new functions:
1934 silc_server_command_identify_parse
1935 silc_server_command_identify_send_reply
1936 silc_server_command_identify_from_client
1937 silc_server_command_identify_from_server
1939 * Disabled route cache adding because adding two different ID's with
1940 same IP replaces the old cache entry thus giving wrong route.
1941 The entry->router->connection is always the fastest route anyway
1942 so route cache may not be needed. Of course, new routes maybe
1943 established after receiving the ID when the entry->router->connection
1944 might not be anymore the most optimal.
1946 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1948 * Add route cache for received ID for fast routing.
1950 * Added silc_server_packet_route to route received packet on router
1951 that is not destined to us.
1953 * Renamed silc_server_get_route to silc_server_route_get.
1955 * Added id_string and id_string_len fields into SilcServer to
1956 include encoded ServerID for fast comparing without excess
1957 encoding of the ID's.
1959 * Cleaned up WHOIS command on server side. Added following static
1962 silc_server_command_whois_parse
1963 silc_server_command_whois_check
1964 silc_server_command_whois_send_reply
1965 silc_server_command_whois_from_client
1966 silc_server_command_whois_from_server
1968 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1969 arguments in command replies. All command functions should be
1970 updated to use this macro.
1972 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1974 * Minor typo fixes on command reply handling on server.
1976 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added silc_server_command_add_to_channel internal routine to add
1979 the client to the channel after router has created the channel and
1980 sent command reply to the server.
1982 * Added generic silc_server_send_command to send any command from
1985 * Use static buffer with ID rendering instead of duplicating data.
1987 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Fixed a channel user mode bug when joining to a channel server gave
1990 everybody channel founder rights, oops.
1992 * We mark ourselves as the router of the incoming server connection
1993 if we are router ourselves. This way we can check in some packet
1994 sending functions whether it is locally connected server. For
1995 incoming router connections we put NULL.
1997 * For router sending packets locally means now always sending the
1998 packet cell wide; to local clients and local servers. For normal
1999 server sending packet locally means sending it to only local
2002 * Fixed the JOIN command to really work in router environment. If the
2003 channel is created it is always created by the router. Router is
2004 also responsible of making the initial joining to the channel,
2005 sending JOIN notify to the sending server and distributing
2006 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2007 does not exist server doesn't do anything else but forward the
2008 command to the router which performs everything.
2010 * Added silc_server_send_channel_key function to send the Channel Key
2013 * Added silc_server_create_channel_key to create new channel key. The
2014 channel key is now re-generated everytime someone joins or leaves
2015 a channel, as protocol dictates. Note: channel->key_len is the
2018 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2021 packet_receive.[ch] to separate packet sending and receiving
2022 routines. The server.[ch] now includes everything else including
2023 actual packet processing (writing and reading data) and other
2026 Renamed silc_server_private_message_send_internal to
2027 silc_server_send_private_message. The routine is still though
2028 used only to relay private messages as server does not send
2029 private messages itself.
2031 Renamed silc_server_new_channel to silc_server_create_new_channel
2032 and added new function sicl_server_new_channel that handles the
2033 incoming New Channel packet. Added also new sending function
2034 silc_server_send_new_channel to send New Channel Payload.
2036 * Added new function silc_server_notify to process incoming notify
2037 packet to the server/router. Server may then relay the notify
2038 to clients if needed.
2040 * Added new function silc_server_new_channel_user to process incoming
2041 New Channel User packet. Router will redistribute the packet and
2042 send JOIN notify to its local clients and locally connected servers
2043 if needed. Normal server will send JOIN notify to its local client
2044 on same channel when received this packet. Added also corresponding
2045 sending function silc_server_send_new_channel_user to sent the
2048 * Added boolean route argument to send_notif_to_channel and
2049 packet_send_to_channel functions to attempt to route the packet
2050 if it is TRUE and send only locally if it is FALSE.
2052 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * silc_server_replace_id now broadcasts the received replace ID
2055 packet if it is not broadcast packet already. The router must
2056 broadcast to inform other routers about changed ID.
2058 * Added backpointer to server's router into SilcServer context in
2059 silcd/server_internal.h.
2061 * Fixed silc_server_packet_broadcast to send correct broadcast
2064 * The channel key is now distributed to the local client as soon
2065 as it is received from the router (in router environment) so that
2066 no other packet may be sent for the channel until client has
2069 * silc_server_remove_channel_user now broadcasts the received
2070 Remove Channel User packet if it is not broadcast packet already.
2071 The router must broadcast to inform other routers about removed
2074 * Added users field into SilcPacketContext that is a reference count
2075 of the context. One can increase the reference count by calling
2076 silc_packet_context_dup which is now changed to just increase the
2077 reference count instead of duplicating the data. The reference
2078 count is decresed by calling silc_packet_context_free that will
2079 free the data after the reference count hits zero.
2081 For now on the packet context and everything allocated into it
2082 (including the raw packet from network) must be freed by calling
2083 the new silc_packet_context_free function. Added also new function
2084 silc_packet_context_alloc that must be used now to allocate the
2085 context. This also means that if a routine is asynchronous from
2086 silc_[client/server]_packet_parse_type the packet context must
2087 be duplicated by calling silc_packet_context_dup. Otherwise it
2088 gets free'd after silc_[client/server]_packet_parse_type returns.
2089 Also, one must remember that if packet is duplicated then its
2090 reference count must be decresed by calling the free function as
2091 many times as it was duplicated.
2093 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2094 from both client and server.
2096 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Made joining to a channel working in router environment.
2100 * Cleaned up JOIN command on server side and create function
2101 silc_server_command_join_channel internal routine to make the
2104 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Changed silc_command_pending list to SilcDList. Also, added
2107 `ident' field to SilcServerCommandPending structure to identify
2108 the reply and to call correct callback.
2110 Added silc_server_command_pending_check function to replace the
2111 corresnponding macro. The silc_command_pending list is not
2114 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2115 to set identifier to previously allocated Command Payload. It
2116 is used to set identifier for command when resending Command
2119 * Added silc_command_payload_encode_payload to encode Command
2120 Payload buffer from SilcCommandPayload structure.
2122 * Added silc_argument_payload_encode_payload to encode Argument
2123 payload buffer from SilcArgumentPayload structure.
2125 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Changed WHOIS command to support router connection on server side.
2128 The whois request is always sent to router unless the server is
2129 standalone server. After server has received the reply from the
2130 router will it send the reply to the client.
2132 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2133 broadcast received broadcast packet. The function is used only
2134 by router. The broadcast packet is always sent to the router's
2137 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2138 render given ID to printable string, for log files for example.
2140 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Made basic router to router connections working. At least they
2143 can now connect to each other but nothing really works the way
2144 they are supposed - yet.
2146 * Added new initiator token to RouterConnection configuration
2147 file in silcd/serverconfig.[ch]. It is used to tell whether we
2148 are the initiator to the remote router or whether we'll expect
2149 the other end to connect.
2151 * Moved registering of listener task to silc_server_init, hence
2152 the server starts listenning as soon as it is run, even if it
2153 does not have connections to other routers. Let's see how well
2156 * Changed default connection retry timeouts for more suitable in
2159 * Removed cipher and such arguments from silc_idlist_add_client
2160 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2161 Added new function silc_idlist_add_data to add the keys and stuff
2164 * Added SilcIDListData structure and added it to SilcClientEntry
2165 and SilcServerEntry as their first field in the structure. This
2166 way we can explicitly cast the ID entries to the SilcIDListData
2167 structure and get common data for the entries. In past, we had
2168 to first check what type of connection it is and then cast it to
2169 correct ID entry type. Now, we can directly cast the opaque
2170 pointer to the SilcIDListData (no matter what ID entry it actually
2171 is) and get the data needed.
2173 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2176 in some circumstances even if threre were timeout tasks, though not
2177 IO tasks, but tasks anyway. Now fixed.
2179 * Defined SilcServerConnection structure to hold connection specific
2180 stuff about directly connected servers and routers. The definition
2181 is currently in silcd/server_internal.h. I thought about having
2182 a bit more important role fro this struct but for now it is used
2183 only when connecting to other server (or router actually).
2185 * Added connecting retry support in server when connecting to
2186 router(s). The retry feature implement exponential backoff
2187 algorithm. Also, added SilcServerParams structure to hold default
2188 parameters for server. For now, it include these retry settings
2189 and are hard coded. After server is moded to be as Silc Server
2190 Library this structure will be more important.
2192 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Changed client librarys channel->clients table to SilcList and
2195 changed code accordingly.
2197 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Changed client's channel table to SilcList and changed code
2200 accordingly. Also changed SilcChannelClientEntry to include back-
2201 pointer to the channel so that client entry can use that structure
2202 as list as well and we have fast cross-reference to the channel.
2203 This change dramatically decreased the complexity of channel
2204 handling with client entry and vice versa (removed one extra
2205 loop when searching for channel entry from many functions).
2207 * Changed server->sim from table to SilcDList and changed code
2210 * NAMES command can now be used from user interface. It will show
2211 the user list on the channel, neatly.
2213 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2214 Code now saves realname of the user if it becomes available.
2216 * Renamed configure.in to configure.in.pre and made ./prepare
2217 script to automatically add correct version string to
2218 configure.in which it creates from configure.in.pre.
2220 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * NAMES command reply now shows users mode with the nickname when
2225 * Moved silc_client_ch[u]mode[_char] functions from
2226 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2227 place sucks, they are utility functions and should be in some
2230 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2232 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2235 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added TRQ (efficient deque and list library) into lib/trq. This is
2240 a very good list library that is currently used in the SILC. Defined
2241 SilcList API over the library because I didn't like the API very
2242 much. See lib/trq/silclist.h for the API and examples of how to
2243 use the API. Fixed various places in the code to use the new
2244 SilcList API. The SilcList is meant for lists that has a structure
2245 already defined as a list. It is not suitable to add just some
2246 context to the list (in TRQ, the context is the list actually).
2248 So, I defined SilcDList that can be used for the purpose where
2249 predefined list structure does not exit. This can be used as
2250 such list. Now some context just can be added to the SilcDList.
2251 Currently this list is not used in the SILC just yet, though there
2252 are a lot places where this can replace dynamically allocated
2253 tables and I will fix these places, later, to use SilcDList.
2254 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2255 and use TRQ internally).
2257 Also fixed some annoying warning messages that the original TRQ
2258 code generated. Also minor changes to TRQ's Makefile.in.
2260 * Added support for querying by Client ID to both WHOIS and
2261 IDENTIFY commands into server, as required by the protocol.
2263 * Removed method function pointers from SilcBuffer structure. They
2264 weren't used to anything and just increased the context size for
2265 no good reason. This change also made silc_buffer_alloc and
2266 silc_buffer_free functions inline functions.
2268 * Disabled command flooding detection support until it's fixed so
2269 that it accepts commands in but does not execute them more than once
2272 * Added silc_net_localhost(), to return local hostname, into
2273 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2274 that must be initialized before calling silc_client_init.
2276 * Added new function: silc_server_send_notify_on_channels to send
2277 notify messages to all channels client has joined. It is assured
2278 that the message is sent only once per client.
2280 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2281 lib/silcutil/silcutil.[ch] as silc_format function. The new
2282 function is generic and is used by server as well, not only by
2283 the logging routines.
2285 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2286 the provided version string was not acceptable. Added new function:
2287 silc_ske_check_version into lib/silcske/silcske.h. The function
2288 must be implemented by the application (client or server) and it
2289 does not reside in the SKE library. The function checks the version
2290 string remote end sent.
2292 * Added back pointers (to opaque context and to SilcSocketConnection)
2293 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2295 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2296 duplicate packet context structure.
2298 * Changed `notify' client operation to send same arguments as client
2299 receives from server except for ID's. ID's are mapped to correct
2300 ID entry and that is returned. Also, if channel entry is not sent
2301 by server but the notify is for channel the channel entry is sent
2302 to application (otherwise application doesn't know that it is for
2303 channel (library gets it from packet's Destination ID)).
2305 * Added silc_client_remove_from_channels into client library to
2306 remove a client from all channels it has joined to. Used when
2307 received SIGNOFF notify from server. Added also new function
2308 silc_client_replace_from_channels to replace old ID entry with
2309 new ID entry on all channels. Used when received NICK_CHANGE
2312 * Fixed ID Cache list handling in silc_idlist_get_client in
2313 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2314 to get (or query) client by ID.
2316 * Updated TODO list.
2318 * Added connection authentication status message defined by the
2319 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2320 support for these into the code in client and server side.
2322 * Added generic function silc_client_send_command to send any command
2323 with variable argument list. Application should use this function
2324 to send commands if the command functions provided by the library
2325 does not suite for the application's user interface needs.
2327 * Added new `failure' client operation. Application is notified about
2328 received failure packet if client is executing a protocol. In this
2329 case the protocol's execution has failed.
2331 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2332 is required by the protocol.
2334 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2335 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2338 * Added status flag to SilcSKE object to indicate realtime status
2339 of the SKE protocol.
2341 * Application receives now exactly same command reply arguments as
2342 the library receives from server. However, if ID is received the
2343 corresponding ID entry is returned to the application (eg. Client
2344 ID is mapped to correct SilcClientEntry entry and that is returned).
2345 Changed command_reply client operation due to this change.
2347 * Changed all ID's in commands and in command replys as ID Payloads.
2348 Change affected both client and server side codes.
2350 All ID's sent in SILC network (with execption of ID's in SILC
2351 Packet header) are sent in ID Payload to support variable length
2354 * Server now notifies nick changes and notifies all clients on
2355 the channels about the new nickname (about the new Client ID,
2358 * Implemented CMODE command to change channel modes. Supports all
2359 channel modes defined by the protocol specs except ban and invite
2360 lists. (Also, private channel key mode is supported but support for
2361 setting private channel key in client is missing, thus, this mode
2362 has no effect on client side (except that server requires that the
2363 client uses private channel key and normal channel traffic does not
2366 Also, invite mode works per se, but INVITE command does not work
2367 yet correctly, so you can set channel as invite only channel but
2368 inviting clients to the channel does not work (it is yet to be
2369 thought what's the best way to do it).
2371 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2372 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2373 Implemented CUMODE command to change user's mode on the channel.
2374 Supports all modes defined by the protocol specs.
2376 * Added NAMES command reply to return users modes on the channel.
2378 * Removed unnecessary and slow ciphers from lib/silccrypt.
2380 * Set SO_KEEPALIVE option to connection sockets by default.
2382 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2384 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2385 redefined the Notify Payload into protocol specs.
2387 * Added silc_id_payload_parse_id to get ID directly from raw
2390 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2393 accept searching by Client ID as well.
2395 * Added support for LEAVE and SIGNOFF notify types in client library.
2397 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2398 to parse ID Payload from raw data.
2400 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Added flags parameter into silc_ske_assemble_security_properties
2403 function in lib/silcske/silcske.[ch].
2405 * Changed notify client operation to fit better for notify messages
2406 sent by server. The notify payload received from server is now
2407 passed to the application (after parsing it to SilcNotifyPayload).
2408 It is application's responsibility to retrieve the arguments
2409 from the payload and show the message the way it wants. The message
2410 sent by server is implementation specific.
2412 * Changed public keys to comply with the protocol specification.
2413 Old public keys are not supported anymore and are not compatible.
2415 * Removed nickname from Channel Payload as the latest draft removed
2416 it. The client must resolve the nickname from the NAMES command
2417 reply received when it joined the channel.
2419 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2421 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Fixed some errors in protocol specification drafts.
2425 * Created lib/silccore/silcnotify.c to implement Notify Payload
2426 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2427 generic payloads described by protocol specifications. The file
2428 includes implementations for ID Payload and Argument Payload.
2430 * Changed Command Payload implementation to use the new Argument
2431 Payload. Changed command_xxxx_payload to command_payload_xxxx
2432 to comply with SILC coding conventions.
2434 * Added suppport for Argument Payload handling in Notify Payload
2435 implementation as protocol requires it. Added the new support
2436 into server and client lib as well.
2438 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added support for multiple nicknames on same channel. [n] is
2441 added locally to the nickname if there are more than one same
2442 nicknames on the channel.
2444 * Server now sends all nicknames that matched WHOIS request.
2445 Client also shows the list received from server.
2447 * Added TOPIC command to client side. User can now set and show
2448 current topic on channel.
2450 * Added MOTD command to client and server. Also, server sends the
2451 motd when client connects to the server.
2453 * Changed version strings to comply ISO 8601.
2455 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Fixed protocol error handling in client library. It should now
2458 cope even if the SKE fails for some reason.
2460 * Made new protocol specification drafts for submitting to IETF.
2462 * Implemented TOPIC command to server in silcd/command.c.
2464 * Added two new notify types into lib/silccore/silcnotify.h:
2465 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2466 notify nickname change and topic setting/change on a channel.
2468 * API change of command_reply operation in client library. The
2469 application gets now the status type received from server as well.
2471 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2475 * Cras fixed and optimized the packet handling even further and
2476 it should work now. Minor change to the prototype of function
2477 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2479 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Added new function into lib/silcutil/silcschedule.[ch]:
2482 silc_schedule_with_fd to select() a specified fd. The function
2483 returns after timeout expires or data arrives or goes. The
2484 function is used by packet routines to wait that all data is
2485 received from network.
2487 * Fixed data reading from network in lib/silccore/silcpacket.c.
2488 The code now assures that all data is read from the fd and then
2489 continues packet processing. This was a bug fix since the code
2490 used to drop some data in some circumstances.
2492 * Added new function into lib/silcclient/client.[ch]:
2493 silc_client_start_key_exchange to start key exchange after
2494 connection has been established to server. The code internally
2495 now uses this funtion but its main purpose was to provide it
2496 for applications that perform their own connecting. After
2497 application has created a connection it merely calls this
2498 function to start the key exchange between client and server.
2499 The library takes care of everything else after that.
2501 Updated also lib/silcclient/README to explain the usage of
2504 * Do not send to application information that connection has
2505 been established. Application gets notified it by connect
2508 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Applied cras's patch to add silc_schedule_one function. The
2511 function runs scheduler once and returns.
2513 * Fixed the scheduler after cras messed it up. The timeout
2514 handling works now as it's supposed to work.
2516 * Added into lib/silccore/ silcnotify.h to include notify
2517 message types support. Changed silc_server_send_notify*
2518 functions, in server.[ch], to support those new notify types.
2519 Added the support for the notify types into client library,
2520 as well. Added new notify client operation into ops.h in
2523 * Changed silc_server_packet_send_to_channel to send normal
2524 packets instead of just channel message packets. The function
2525 is now used to send the notify packets to channels. It is not
2526 used to send channel message packets anymore, as server never
2529 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2530 va_arg()s as it seems to require it nowadays. I guess, if SILC
2531 is compiled with older va_arg() the new code should work anyway.
2533 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Splitted core library. Core library (lib/silccore) includes
2536 now only SILC protocol specific core (and common) components.
2537 Created new utility library (lib/silcutil) that includes more
2538 generic purpose stuff. The stuff for util library was taken
2539 from the old core library. This was minor and easy split.
2541 * Created SILC Client Library (lib/silcclient) that includes
2542 implementation of the SILC client without user interface. This
2543 was major move from silc/ directory. The code has been changed
2544 so that it is transparent towards the user interface. The
2545 silc/ directory includes now the same user interface as before
2546 and it uses the new client library. Read lib/silcclient/README.
2547 Basicly, the client library performs everything else related
2548 to SILC except user interface handling. Also, configuration
2549 files are considered to be part of user interface and library
2550 does not handle them.
2552 This change also changed a lot of structures, function naming etc.
2553 Most important change was that SilcClientWindow object was
2554 renamed to SilcClientConnection in the client library. Created
2555 also new file lib/silcclient/ops.h. Also added new files
2556 silc/local_command.[ch] and silc/client_ops.[ch].
2558 All these changes were made to make it easier for user interface
2559 designers to create what ever user interface for the SILC client
2562 It is also expected that the server will be moved to lib
2563 directory as well and SILC Server Library will be created;
2564 sometimes in the future.
2566 * Removed Local commands from lib/silccore/silccommand.h as
2567 they are application specific and new client library does not
2568 handle any of those anymore.
2570 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2571 old client implementation in silc/.
2573 * Added support for callback functions in SILC_LOG_* macros.
2574 Application can now set its own callbacks that will be called
2575 instead of using the default functions that will always print
2576 the debug messages to stderr (or stdout). Also, debugging can
2577 now be disabled by setting silc_debug to FALSE and re-enabled by
2578 setting it to TRUE. Note, that logging will still work even
2579 if debugging is disabled.
2581 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2582 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2583 silc_log_reset_debug_callbacks.
2585 * To enable debugging in silc client one must give now -d
2586 option on command line.
2588 * Changed silc_schedule_init to automatically allocate task queues
2589 if they are not allocated before calling it.
2591 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added GMP 3.1 into math library.
2595 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2597 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2598 a channel in SILC network. The packet is used by servers and
2599 routers to notify other routers that user has left a channel.
2600 This little feature was missing until now. Added the feature
2601 to protocol specification as well.
2603 Added functions: silc_server_send_remove_channel_user and
2604 silc_server_remove_channel_user into server.[ch].
2606 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2607 lib/silccore/silcpacket.h. However, they are not implemented
2610 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Fixed joining to a channel and sending channel messages
2613 between server and router. The channel message sending should
2614 now work inside a cell.
2616 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Fixed the private message sending between server and router.
2619 The private message sending should now work inside a cell.
2621 * Added silc_server_replace_id into server.[ch] to replace
2622 existing ID in the SILC network.
2624 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2625 and silc_idlist_replace_server_id into idlist.[ch] in server.
2627 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Fixed the server to server connections. Server can again now
2630 connect to router. Router to router connections probably does
2633 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added dynamic protocol registering support. Now protocols can
2636 registered and unregistered on the fly. Patch by cras.
2638 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Added lib/contrib directory to hold routines that some platforms
2641 don't have but are needed by SILC.
2643 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2644 into lin/contrib to provide getopt() and getopt_long() for
2645 those who don't have it.
2647 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Added AWAY command to client. When away message is set and
2650 client receives a private message packet the client automatically
2651 replies to the sender with the away message.
2653 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2654 bug seemed to be the cause of recent problems when compiling
2657 * Added version detection support to SKE protocol specification
2658 and added the new changes to the SKE implementation as well.
2659 There were other minor changes in the SKE protocol as well.
2661 Many changes in lib/silcske/silcske.[ch] and in
2662 lib/silcske/payload.[ch].
2664 * Added ^U functionality, clear input line. Patch from cras.
2666 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Mainly small bugfixes on core library. Fixed some debugging
2669 logging and buffer overflow in silclog.c.
2671 * Updated config.sub and config.guess on the distribution tree.
2673 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Added command lagging support in server. Client may execute
2676 commands now only once in two seconds.
2678 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Optimized packet reception. MAC computation and checking is now
2681 also more optimized. A lot previously duplicated code is now
2682 used as generic by both client and server.
2684 * Fixed key pair generation in clientutil.c
2686 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Added into lib/silccore/silcbufutil.[ch] new function;
2689 silc_buffer_realloc.
2691 * Moved generic packet sending/encryption functions to
2692 lib/silccore/silcpacket.[ch] from client and server. Some
2693 rewriting of the functions.
2695 * Moved all generic packet reception/decryption functions to
2696 lib/silccore/silcpacket.[ch] from client and server. The
2697 packet processing is now much cleaner in both client and server.
2698 These were major changes in both client and server.
2700 * Created many common functions in server to do packet sending.
2701 Previously code were duplicated a lot, this has been removed
2704 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Rewrote major parts of the ID cache system. Don't know
2707 whether it is better now or not but at least the API is more
2710 * Major rewrite on ID cache stuff on client because of the ID
2711 cache API changes. Added idlist.c to client.
2713 * Also major rewrite on ID cache stuff on server as well.
2714 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2715 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2716 in hand, instead they are all put into the ID cache system now.
2717 All server_idlist_* routines uses ID cache now instead of
2718 traversing its own lists (those lists does not exist anymore).
2719 SilcIDList though still exists. Also, SilcXXXEntry's are
2722 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Finally made the SKE implementation compliant to the protocol
2725 specification. All mp integers are now binary encoded as
2726 opposed being HEX encoded.
2728 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2731 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2732 functions: silc_[encode/decode]_pem. Also added function
2733 silc_encode_pem_file to PEM encode with newlines ('\n') for
2736 * SILC public keys are now encoded either PEM or binary. Same
2737 option is for private keys as well. By default private keys
2738 are binary encoded and public keys PEM encoded. Silly HEX
2739 encoding were removed.
2741 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2742 function to create fingerprints.
2744 * Fixed a bug in SHA1; does not change the original data anymore.
2746 * Partly implemented INFO command on client and server side.
2747 Fixed CLEAR command. Changes to SERVER command; show current
2748 server(s) when giving command without arguments. Added
2749 VERSION command to client.
2751 * Added check to server that unregistered connections cannot
2752 execute commands (unless it is specificly allowed).
2754 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Fixed screen refresh.
2758 * Fixed channel joining bug from client. On some circumstances
2759 client tried to join to a channel it had already joined.
2761 * Added public key verification process into client's protocol.c.
2762 The client now verifies the public key from user and saves
2763 it into ~./silc/serverkeys/ directory.
2765 Added into: clientutil.[ch]: silc_client_verify_server_key.
2767 * Changed SKE protocol's silc_ske_initiator_finish function
2768 to accept callback function that verifies the received public
2769 key. Removed old silc_ske_verify_public_key function.
2771 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2774 silc_pkcs_private_key[_data]_set.
2776 * Made the password and public authentication more cleaner in
2777 server's protocol.c.
2779 * Removed historic and obsolete protocol `channel_auth' from
2780 both client and server.
2782 * Removed wrong way of sending command status messages from
2783 server to client in server's command.c. The old way violated
2784 protocol specification.
2786 Changes to silccore/silccommand.[ch]: removed
2787 silc_command_encode_status_payload -> not needed anymore,
2788 changed silc_command_encode_payload_va to accept extra
2789 argument on variable argument list. The argument type must
2790 now be provided to the function. Also, added new function:
2791 silc_command_encode_reply_payload_va which is same as
2792 normal command_encode_payload_va except command status type
2793 is provided as extra argument.
2795 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Added ~./silc directory handling. The directory includes the
2798 public and private keys for the client.
2800 Added silc_client_check_silc_dir, silc_client_create_identifier
2801 and silc_client_load_keys.
