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

175 notify between routers.
177 * Implemented the INVITE command correctly to the server.
179 * Implemented the INVITE notify type handling in the server.
181 * Implemented the INVITE command to the client library and on the
184 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Added function silc_server_get_client_resolve to find the
187 client entry by ID from all ID lists and then resolve it
188 (using WHOIS) if it cannot be found. Affected file is
191 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Implemented the BAN command to the client library.
195 * The JOIN command in the server now checks the invite list
198 * Changed the silc_command_reply_payload_encode_va and the
199 silc_command_payload_encode_va to support that if argument is
200 NULL it ignores and checks the next argument. Affected file
201 lib/silccore/silccommand.c.
203 * Added silc_server_send_notify_ban to send the BAN notify
204 type between routers.
206 * Chaned the silc_notify_payload_encode to support that if
207 argument is NULL it ignores and checks the next argument.
208 Affected file lib/silccore/silcnotify.c.
210 * Tested ban lists in router environment successfully.
212 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Implemented BAN command to the server, in silcd/command.[ch].
216 * Removed the BAN and INVITE_LIST modes from the CMODE command
219 * Added function silc_string_match to regex match two strings.
220 Affected files lib/silcutil/silcutil.[ch].
222 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
224 * Redefined parts of the SilcChannelEntry in the server to support
225 the new ban and invite lists.
227 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Redefined the INVITE command. The same command can be used to
230 invite individuals to the channel but also to manage the invite
231 list of the channel (to add to and remove from the invite list).
232 Updated the protocol specs.
234 * Added new command SILC_COMMAND_BAN that can be used to manage
235 the ban list of the channel. Updated the protocol specs.
237 * Removed the channel modes: the SILC_CMODE_BAN and the
238 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
239 in the CMODE command. The equivalent features are now available
240 using INVITE and BAN commands. Updated the protocol specs.
242 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
243 in the network about change in the current ban list. The notify
244 type is not used by the client.
246 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
247 support the invite lists.
249 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Added new function silc_string_regexify that converts string
252 including wildcard characters into regex string that can
253 be used by the GNU regex library. Added into the file
254 lib/silcutil/silcutil.[ch].
256 Added silc_string_regex_combine to combine to regex strings
257 into one so that they can be used as one regex string by
258 the GNU regex library. Added into the file
259 lib/silcutil/silcutil.[ch].
261 Added silc_string_regex_match to match two strings. It returns
262 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
264 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Imported GNU regex to the soruce tree into lib/contrib.
267 Fixed some compiler warning from the regex.c.
269 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Fixed MOTD command in the server to work in router environment.
273 * Fixed the MOTD command in the client library to support
274 the server argument in the command.
276 * Added `nickname_len' argument to the silc_idlist_add_client
277 in the server, as the `nickname' argument may be binary data
280 * Added silc_idlist_get_channels to return all channels from
283 * Implemented LIST command to the server. Affected file is
286 * Implemented the LIST command to the client library and on the
289 * Added [<user count>] argument to the LIST command reply.
290 With private channels the user count is not shown.
292 * Updated TODO and README.
294 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * The client entry's data.registered must be TRUE even with
297 global client entry on global client list. The data.registered
298 is used to check whether the client is anymore in the network,
299 for example with WHOWAS command so it must be valid.
301 * Fixed the WHOWAS command in the server. It now actually works
302 in router environment. Added function into silcd/command_reply.c
303 silc_server_command_reply_whowas_save.
305 * Added silc_idlist_purge function to the silcd/idlist.c
306 to periodically purge the ID Cache.
308 * Fixed INFO command in the server. It works now in router
309 environment. Added <server name> argument to the INFO command
310 reply. Updated the protocol specs.
312 * Fixed minor bug in silc_idcache_purge to not purge if the
313 expire value is zero.
315 * Fixed various bugs in WHOIS and IDENTIFY command handling as
316 they were buggy because of the WHOWAS information.
318 * Fixed local command MSG to handle the async resolving of
319 the remote client properly. It used to fail the first MSG.
320 Affected file silc/local_command.c.
322 * Added `data_len' field to SilcIDCache context.
324 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Update TODO. Todo in commands in the server.
328 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
331 used by routers as broadcast packet to inform other routers
332 about the changed user mode.
334 Implemented the notify handling in the server. Affected file is
335 silcd/packet_receive.c. Added the function
336 silc_server_send_notify_umode to the silcd/packet_send.[ch].
338 * Added new generic Channel Payload and deprecated the New Channel
339 Payload. The New Channel Payload is now the generic Channel
342 * Added new argument `mode' to the silc_server_send_new_channel
343 as it is required in the Channel Payload now.
345 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
346 and created a new and real SilChannelPayload to represent the
347 new generic Channel Payload. Implemented the encode/decode
348 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
350 * Added silc_server_get_client_channel_list to return the list
351 of channels the client has joined for WHOIS command reply.
352 Affected file silcd/server.[ch].
354 * Implemented the channel list sending in the WHOIS command reply
355 in server and in the client.
357 Implemented the channel list displaying on the user interface
358 as well. Affected file silc/client_ops.c.
360 * Added silc_channel_payload_parse_list to parse list of Channel
361 Payloads. It returns SilcDList list of SilcChannelPayloads.
362 Client for example can use this function to parse the list of
363 channels it receives in the WHOIS command reply. The caller
364 must free the list by calling silc_channel_payload_list_free.
365 Affected files lib/silccore/silcchannel.[ch].
367 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Added one new argument <user mode> to the WHOIS command reply
370 to return the mode of the user in SILC. Updated the protocol
373 Implemented it to the server and client.
375 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Fixed the mode printing on the user interface on joining.
378 Affected file silc/client_ops.c.
380 * Implemented the UMODE command and user modes in general to the
381 client library and to the user interface.
383 * Implemented the UMODE command to the server.
385 * The server now sends UNKNOWN_COMMAND error status if client sends
386 unknown command. Affected file silcd/command.c.
388 * All server commands now handle the command identifier the right
389 way when sending the command reply to the client. The client can
390 use to identify the command replies with the identifier.
392 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Added silc_server_get_client_route to resolve the route to
395 the client indicated by the client ID. Affected file is
398 * Added silc_server_relay_packet as general function to relay
399 packet to arbitrary destination. This deprecates functions
400 like _send_private_message_key, _relay_notify etc. Affected
401 file is silcd/packet_send.[ch].
403 Removed silc_server_send_key_agreement,
404 silc_server_send_private_message_key and
405 silc_server_packet_relay_notify functions from the file
406 silcd/packet_send.[ch].
410 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
411 server. Affected file silcd/packet_receive.[ch].
413 * Implemented the KILL command to the client. Implemented the
414 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
415 Affected files lib/silcclient/command[_reply].c and
416 lib/silcclient/client_notify.c. Implemented the KILL notify
417 printing in the user inteface.
419 * Fixed a lot silc_parse_nick memory leaks from the client
420 library in the file lib/silcclient/command.c.
422 * Changed the silc_server_send_notify_on_channels's `sender'
423 argument from SilcSocketConnection to SilcClientEntry to
424 check the sender as entry and not as connection object and not
425 to send to the client provided as argument. The affected file
426 is silcd/packet_send.[ch].
428 * The notify packets that are destined directly to the client used
429 to not to be processed by the server. Now changed that and the
430 server processes all notify packets. After relaying the packet
431 to the client the notify packet is processed in the server.
433 * The silc_server_free_client_data now checks whether there is
434 pending outgoing traffic for the client and purges the data to
435 the network before removing the client entry.
437 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
440 an client is killed from the SILC Network. Updated the protocol
443 Added new function silc_server_send_notify_killed to the
444 silcd/packet_send.[ch].
446 * Added function silc_server_packet_relay_notify to relay notify
447 packets that are destined directly to a client. In this case
448 the server does not process the notify packets but merely relays
449 it to the client. Affected file silcd/packet_send.[ch].
451 Added also silc_server_packet_process_relay_notify to check
452 whereto relay the notify. Affected file is
453 silcd/packet_receive.[ch].
455 * Implemented the KILL command to the server.
459 * Added the backup schema desgined last fall to the protocol
460 specs for everyone to see. The specification is in the
461 *-spec-xx.txt draft and the packet type definitions for the
462 backup routers is in *-pp-xx.txt draft. Thusly, added also
463 new packet type SILC_PACKET_CELL_ROUTERS.
465 * A big security problem in the implementation discovered. The
466 signoff of an client did not cause new channel key generation
467 which it of course should've done. The channel keys must be
468 always re-generated when client leaves (or signoffs) the channel.
469 The silc_server_remove_from_channels funtion now handles
470 the channel key re-generation.
472 * Added `sender' argument to the silc_server_send_notify_on_channels
473 to not to send the client provided as argument. Affected file
474 silcd/packet_send.[ch].
476 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Implemented OPER and SILCOPER commands into the server and
481 * Added silc_auth_verify and silc_auth_verify_data to verify
482 the authentication directly from the authentication payload.
483 It supports verifying both passphrase and public key based
484 authentication. Affected file lib/silccore/silcauth.[ch].
486 * Added `hash' field to the SilcIDListData structure. It is the
487 hash negotiated in the SKE protocol. Affected file is
490 * Slight redesigning of the SilcAuthPayload handling routines.
491 Do not send SilcPKCS but SilcPublicKey as argument.
493 * Implemented the public key authentication support to the
494 serverconfig. The public key is loaded from the provided path
495 and saved as authentication data to void * pointer. Thus,
496 changed the unsigned char *auth_data to void *auth_data;
498 * Fixed SHUTDOWN command to send the reply before the server
499 is shutdown. :) Affected file silcd/command.c.
501 * Fixed fatal bug in CONNECT command. The hostname was invalid
502 memory and server crashed. Affected file silcd/command.c.
504 * Fixed fatal bug in CLOSE command. The server_entry became
505 invalid but was referenced later in the command. Affected file
508 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Fixed fatal bug in failure packet handling. Server ignored
511 the failure and thus crashed when it came.
515 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
518 that the command may be executed only once in (about) 2 seconds.
519 The old SILC_CF_LAG flag is same but allows command bursts up
520 to five before limiting.
522 Added the support for CF_LAG and CF_LAG_STRICT flags to the
523 server code. Various commands now includes the CF_LAG_STRICT
524 flag to disallow any kind of miss-use of the command.
526 * Fixed the silc_buffer_unformat to not to allocate any data
527 if the length of the data is zero. It used to allocate the
528 length + 1. Affected file lib/silcutil/silcbuffmt.c.
530 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Changed the format of AdminConnection configuration section
533 in the server. Added username of the admin to the format.
534 Affected files silcd/serverconfig.[ch].
536 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
537 to return admin configuration data by host, username and/or
540 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Implemented WHOWAS command to the server. Added the functions:
544 silc_server_command_whowas_parse,
545 silc_server_command_whowas_send_reply,
546 silc_server_command_whowas_from_client and
547 silc_server_command_whowas_from_server
549 * Added <Client ID> argument to the WHOWAS command reply. Updated
550 the protocol specs accordingly.
552 * Implemented WHOWAS command and command_reply to the client
555 Implemented the WHOWAS printing on the user interface.
557 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added new argument to the WHOWAS command reply, the real name.
560 It is an optional argument. Updated the protocol specs.
562 * Added SilcIDCacheDestructor callback that is registered when
563 the SilcIDCache is allocated. The callback is called when
564 an cache entry in the ID Cache expires, or is purged from the
565 cache. Added into lib/silccore/idcache.[ch].
567 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
568 to destruct the client entries when the cache entry expires.
569 Other ID Cache's in server and in the client library ignores
572 * If the ID Cache entry's `expire' field is zero then the entry
573 never expires. Added boolean `expire' argument to the
574 silc_idcache_add function in the lib/silccore/idcache.[ch].
575 If it is TRUE the default expiry value is used.
577 * Added silc_server_free_client_data_timeout that is registered
578 when client disconnects. By default for 5 minutes we preserve
579 the client entry for history - for WHOWAS command.
581 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added support to the server to enforce that commands are not
584 executed more than once in 2 seconds. If server receives
585 commands from client more frequently, timeout is registered
586 to process the commands. Affected file silcd/command.c.
587 Added new function silc_server_command_process_timeout.
589 * Changed NICK_NOTIFY handling in client library to check that
590 if the client's nickname was changed, so there is no need to
591 resolve anything from the server.
593 * Removed error printing from the WHOIS and IDENTIFY commands.
594 If error occurs then it is ignored silently in the client library.
595 The application, however, may map the received error to
596 human readable error string. The application currently maps
597 the NO_SUCH_NICKNAME error to string.
599 * Made the command status message public to the application. Moved
600 them from lib/silcclient/command_reply.c to
601 lib/silcclient/command_reply.h. The application can map the
602 received command status to the string with the
603 silc_client_command_status_message function.
605 * Added check to the server to check that client's ID is same
606 as the Source ID in the packet the client sent. They must
609 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Added dist-bzip hook to the Makefile.am to make bzip2
612 compressed distributions.
614 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Server now enforces the maximum length for the nickname and
617 the channel as protocol specification dictates. 128 bytes for
618 nickname and 256 bytes for channel name.
620 * Moved the WHOIS printing to the application. The client libary
621 does not print out the WHOIS information anymore, the application
622 must do it. Renamed silc_client_command_reply_whois_print to
623 the silc_client_command_reply_whois_save.
625 The client's idle time is also sent to the application now, and
626 the idle is shown on screen.
628 * Added silc_client_command_reply_identify_save to save the
629 received IDENTIFY entries.
631 * Do not check for channel private keys in message sending and
632 reception if the channel does not have the PRIVKEY mode set.
633 Affected file lib/silclient/client_channel.c.
635 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
637 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
638 just surfaced after chaning the JOIN procedure.
640 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Added silc_client_get_clients_by_list to get client entries
643 from Client ID list, that is returned for example by JOIN
644 and USERS command replies. The application should use this
645 function for example when JOIN command reply is received to
646 resolve the clients already on the channel (library does not
647 do that anymore as USERS command reply is not used in the JOIN
648 procedure anymore). Affected files lib/silcclient/silcapi.h and
649 lib/silcclient/idlist.c.
651 * JOIN command reply and USERS command reply returns now SilcBuffer
652 pointers instead of unsigned char pointers when returning
653 the client list and mode list.
655 * Added <Client ID> argument to the JOIN command reply, mainly
656 for the server to identify for which client the command was
657 originally sent. Updated protocol specs accordingly.
659 * Added SilcDlist private_key pointer to the SilcChannelEntry
660 in the client to support the channel private keys. Affected
661 file is lib/silcclient/idlist.h.
663 * Added SilcChannelPrivateKey argument to the function
664 silc_client_send_channel_message so that application can choose
665 to use specific private ke if it wants to. If it is not provided,
666 the normal channel key is used, unless private keys are set.
667 In this case the first (key that was added first) is used
668 as the encryption key.
670 * Implemented the support for channel private key handling.
671 Implemented the following functions:
673 silc_client_add_channel_private_key,
674 silc_client_del_channel_private_keys,
675 silc_client_del_channel_private_key,
676 silc_client_list_channel_private_keys and
677 silc_client_free_channel_private_keys
679 Affected file lib/silcclient/client_channel.c.
681 * Added the support for the private keys in the channel message
682 sending and encryption and in the message reception and
683 decryption. Affected funtions are
684 silc_client_send_channel_message and silc_client_channel_message.
686 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Added SKE's key verify callback to the client library's
689 KE protocol context. Affected files lib/silcclient/protocol.[ch].
691 * Removed the statement that server (or router) must send USERS
692 command reply when joining to the channel so that the client
693 knows who are on the channel. Instead, the client list and
694 client's mode list is now sent in the JOIN command reply to the
695 client who joined channel. This is better solution.
697 * Added function silc_server_get_users_on_channel and function
698 silc_server_save_users_on_channel to the silcd/server.[ch].
700 * Removed function silc_server_command_send_users from the
703 * Do not show topic on the client library anymore. The topic is
704 sent in the command reply notify to the application and the
705 application must show the topic now.
707 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Added client searching by nickname hash into the IDENTIFY and
710 WHOIS commands in the server as they were clearly missing from
711 them. Affected file is silcd/command.c.
713 * Fixed a bug in private message receiving in the client library.
714 The remote ID was freed and it wasn't supposed, now it is
717 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Minor fix to the channel payload; allocate the data area, as it
720 needs to be of specific length.
722 * If the key agreement port is zero then the operating
723 system will define the bound port. Affected files are
724 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
726 * Added new function silc_channel_payload_decrypt into the file
727 lib/silccore/silcchannel.[ch].
729 * Moved the channel message etc, check from silc_packet_decrypt
730 to applications. The library calls now a generic
731 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
732 when the packet is either normal or special. This was done to
733 allow more wide range of checking that was not allowed when
734 the code was in library. Now applications can do virtually any
735 checks to the packet and return to the library the decision how
736 the packet should be processed. Affected files are
737 lib/silccore/silcpacket.[ch].
739 Added silc_server_packet_decrypt_check to the server and
740 silc_client_packet_decrypt_check to the client library.
742 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
743 to send with specified source and destination information.
745 * Channel message delivery between routers was broken after the
746 channel key distribution was fixed earlier. The channel key
747 was used be to distributed to other routers as well which is not
748 allowed by the protocol. Now this is fixed and channel keys
749 really are cell specific and the channel message delivery between
750 routers comply with the protocol specification.
752 * Fixed various commands in server to check also the global list
753 for the channel entry and not just the local list. The affected
754 file silcd/command.c.
756 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Added assert()s to buffer formatting and unformatting routines
759 to assert (if --enable-debug) when error occurs. Affected
760 file: lib/silcutil/silcbuffmt.c.
762 * Changed to auto-reconnect to check whether the remote host is
763 router and register the re-connect timeout if it is. It used
764 to check that whether we are normal server, but router must do
765 auto-reconnect with another router as well. Affected file
768 * Removed the [<key len>] option from CMODE command as the cipher
769 name decides the key length, nowadays. See the defined ciphers
770 from the protocol specification.
772 * Added [<hmac>] option to the CMODE command to define the HMAC
773 for the channel. Added SILC_CMODE_HMAC channel mode.
775 * Added [<hmac>] option for the JOIN command so that user can
776 select which HMAC is used to compute the MACs of the channel
779 * Added Hmac field to the Channel Message Payload. The integrity
780 of plaintext channel messages are now protected by computing
781 MAC of the message and attaching the MAC to the payload. The
782 MAC is encrypted. Now, it is clear that this causes some
783 overhead to the size of the packet but rationale for this is that
784 now the receiver can verify whether the channel message decrypted
785 correctly and also when private keys are set for the channel the
786 receiver can decrypt the packet with several keys and check from
787 the MAC which key decrypted the message correctly.
789 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
790 lib/silccrypt/silccipher.[ch].
792 * Added silc_hash_len to return the digest length into the
793 lib/silcrypt/silchash.[ch].
795 * Rewrote parts of Silc Channel Payload interface in the
796 lib/silccore/silcchannel.[ch]. The encode function now also
797 encrypts the packet and parse function decrypts it.
799 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Fixed a minor formatting bug in the SKE's key material processing.
802 It actually might have processed the keys wrong way resulting
805 * Redefined the mandatory HMAC algorithms and added new algorithms.
806 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
807 and hmac-md5 truncated to 96 bits. The mandatory is now
808 hmac-sha1-96. Rest are optional (including the one that used
809 to be mandatory). Rationale for this is that the truncated HMAC
810 length is sufficient from security point of view and can actually
811 make the attack against the HMAC harder. Also, the truncated
812 HMAC causes less overhead to the packets. See the RFC2104 for
815 * Added new [hmac] configuration section. The SKE used to use
816 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
817 is of course wrong. The official names that must be proposed in
818 the SKE are the ones defined in the protocol specification
819 (hmac-sha1-96 for example). The user can configure any hmac
820 using any hash function configured in the [hash] section. At
821 least, the mandatory must be configured.
823 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
825 * Added HMAC list to the SKE proposal list. It has now both
826 hash algorithm list and HMAC list. This makes the protocol
827 incompatible with previous versions. The SKE now seems to work
828 the way it is supposed to work, for the first time actually.
830 * Defined plain Hash algorithms to the protocol specification.
833 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Implemented support for key agreement packets into the server.
836 Added functions silc_server_key_agreement and
837 silc_server_send_key_agreement. Other than these functions,
838 server has nothing to do with this packet.
840 * Added support for private message key packets into the server.
841 Added functions silc_server_private_message_key and
842 silc_server_send_private_message_key.
846 * Changed the silc_[client|server]_protocol_ke_set_keys to be
847 called in the protocol's final callback instead in the END
848 protocol state. This makes a little more sense and in the same
849 time in client we can use the same protocol routines for normal
850 key exchange and to key agreement packet handling as well.
852 * Added to both client's and server's KE protocol context the
853 SilcSKEKeyMaterial pointer to save the key material. We will
854 bring the key material to the protocol's final callback by doing
855 this. The final callback must free the key material.
857 * Added SKE's packet_send callback into client's KE protocol
858 context so that the caller can choose what packet sending function
859 is used. This way we can use different packet sending when
860 doing normal SKE when doing key agreement packet handling (in
861 the key agreement packet handling we do not want to encrypt
864 * Implemented the responder side of the key agreement routines
865 in the client. The client can now bind to specified port and
866 accept incoming key negotiation. The key material is passed
867 to the application after the protocol is over.
869 * Implemented the processing of incoming Key Agreement packet
870 in the client. Added function silc_client_key_agreement to
873 * Implemented the intiator side of the key agreement routines
874 in the client. The client can now initiate key agreement with
875 another remote client. The key material is passed to the
876 application after the protocol is over.
878 * Created client_keyagr.c to include all the key agreement
881 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
882 SILC_TASK_CALLBACK except that it is not static.
884 * Created client_notify.c and moved the Notify packet handling
885 from the client.[ch] into that file.
887 * Created client_prvmsg.c and moved all private message and
888 private message key routines from the client.[ch] into that file.
890 * Create client_channel.c and moved all channel message and
891 channel private key routines from the client.[ch] into that file.
893 * Changed silc_client_get_client_by_id_resolve to resolve with
894 WHOIS command instead of IDENTIFY command, in the file
895 lib/silclient/idlist.c.
897 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Implemented the SKE's responder side to the Client library.
901 * When FAILURE is received to the protocol do not trust it
902 blindly. Register a timeout to wait whether the remote closes
903 the connection as it should do it, only after that process the
904 actual failure. This was changed to both client and server.
906 * Added client_internal.h to include some of the structures
907 there instead of client.h in lib/silcclient/.
909 * Added function silc_task_unregister_by_callback to unregister
910 timeouts by the callback function.
912 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Some "Incomplete WHOIS info" errors has been appearing on the
915 log files. Took away the entry->userinfo check from WHOIS
916 reply sending. The entry->userinfo is now " " if client did not
917 provide one. I thought this was fixed earlier but something
918 is wrong still. Let's see if the error still appears.
920 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Fixed a minor bug in the login when the channel key is
923 re-generated in the server. It used to generate the key in
924 wrong order and thus caused problems in the channel traffic.
926 * Fixed a minor bug in channel key distsribution after
927 KICK command. The key was not sent to the router even though
930 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added silc_ske_process_key_material_data as generic routine
933 to process any key material as the SILC protocol dictates. The
934 function is used by the actual SKE library but can be used by
935 applications as well. This relates to the private message keys
936 and the channel private keys since they must be processed the
937 same way the normal SILC session keys. The protocol dictates
938 this. Affected files: lib/silcske/silcske.[ch].
940 Added also silc_ske_free_key_material to free the
941 SilcSKEKeyMaterial structure.
943 * Defined silc_cipher_set_key function to set the key for
944 cipher without using the object's method function. The affected
945 files: lib/silccrypt/silccipher.[ch].
947 * Implemented silc silc_client_add_private_message_key,
948 silc_client_add_private_message_key_ske,
949 silc_client_del_private_message_key,
950 silc_client_list_private_message_keys and
951 silc_client_free_private_message_keys functions in the
954 Added functions silc_client_send_private_message_key to send
955 the Private Message Key payload and silc_client_private_message_key
956 to handle incoming Private Message Key payload.
958 * Added Cipher field to the Private Message Key payload to set
959 the cipher to be used. If ignored, the default cipher defined
960 in the SILC protocol (aes-256-cbc) is used.
962 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Removed lib/silcclient/ops.h file.
966 Redefined parts of the SILC Client Library API. Created new
967 file silcapi.h that deprecates the ops.h file and defines the
968 published Client Library API. Defined also private message key
969 API and channel private key API into the file.
971 This is the file that the application must include from the
972 SILC Client Library. Other files need not be included by
973 the application anymore.
975 * Added new key_agreement client operation callback and also
976 defined the Key Agreement library API for the application.
978 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
981 is used by clients to request key negotiation between another
982 client in the SILC network. If the negotiation is started it
983 is performed using the SKE protocol. The result of the
984 negotiation, the secret key material, can be used for example
985 as private message key.
987 Implemented the Key Agreement payload into the files
988 lib/silccore/silauth.[ch].
990 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Redefined ciphers for the SILC protocol. Added some new ciphers
993 and defined the key lengths for the algorithms. Changed the
994 code accordingly. The default key length is now 256 bits.
996 * Fixed SKE key distribution function silc_ske_process_key_material
997 when the key length is more than 128 bits. The default key
998 length in SILC is now 256 bits.
1000 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1001 to indicate unsupported algorithm.
1003 * Renamed rijndael.c to aes.c and all functions as well.
1005 * Fixed a long standing channel key setting bug in client library.
1006 Weird that it has never surfaced before.
1008 * Fixed bug in channel deletion. If the entire channel is removed
1009 then it must also delete the references of the channel entry
1010 from the client's channel list as the client's channel entry and
1011 the channel's client entry share same memory.
1013 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Implemented CONNECT and SHUTDOWN commands in the client.
1017 * Implemented CLOSE command to the client.
1019 * Added the function silc_idlist_find_server_by_name into the
1020 files silcd/idlist.[ch].
1022 Added the function silc_idlist_find_server_by_conn into the
1023 files silcd/idlist.[ch].
1025 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * DIE command was renamed to SHUTDOWN. Updated the both code
1030 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1031 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1033 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1036 * Added function silc_server_create_connection function to create
1037 connection to remote router. My server implementation actually
1038 does not allow router to connect to normal server (it expects
1039 that normal server always initiates the connection to the router)
1040 so the CONNECT command is only good for connecting to another
1043 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1046 or some other client was kicked from the channel.
1048 Implemented the handling of the notify type to both client
1051 Implemented silc_server_send_notify_kicked to send the KICKED
1052 notify. It is used to send it to the server's primary router.
1054 * Implemented the KICK command into server and client.
1056 * Added `query' argument to the silc_idlist_get_client function
1057 to indicate whether to query the client from server or not if
1060 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1061 to indicate that the client is not channel founder.
1065 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Removed the rng context from SilcPacketContext structure and
1068 changed that the packet routine uses the Global RNG API.
1070 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Added support for quit message that client can "leave" on the
1073 channel when it quits the SILC. It is ditributed inside the
1074 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1076 Added silc_server_free_client_data that will take the
1077 signoff message as argument.
1079 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1081 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1083 * Updated parts of the protocol specification to keep it up
1086 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1089 payloads in one packet.
1091 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1092 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1093 use now the new List flag.
1095 * Also deprecated the following packet types: REPLACE_ID,
1096 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1098 * Added list support for Notify packet in server.
1100 * Added silc_server_send_notify_channel_change to send the
1101 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1102 the silc_server_send_replace_id.
1104 * Added silc_server_send_notify_nick_change to send the
1105 NICK_CHANGE notify type. Deprecates the function
1106 silc_server_send_replace_id.
1108 * Added silc_server_send_notify_join to send the JOIN notify type.
1109 Deprecates the function silc_server_send_new_channel_user.
1111 * Added silc_server_send_notify_leave to send LEAVE notify type.
1112 Deprecates the function silc_server_send_remove_channel_user.
1114 * Added silc_server_send_notify_cmode and
1115 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1116 types. Deprecates the silc_server_send_set_mode function.
1118 * Added SERVER_SIGNOFF notify type to indicate that server has
1119 quit. This means that all clients on the channel from that
1120 server will drop. This can be also used when netsplit happens.
1122 Deprecated REMOVE_ID packet type since it is not needed anymore
1125 Added silc_server_send_notify_server_signoff to send the
1126 SERVER_SIGNOFF notify type. Deprecates the function
1127 silc_server_send_remove_id.
1129 Added also silc_server_send_notify_signoff to send the
1130 SIGNOFF notify type.
1132 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1133 SILC protocol from this day on. Changed the protocol
1134 specification as well.
1136 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1137 notify type. It is used between routers to notify about
1138 topic changes on a channel.
1140 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1143 * Partly updated the protocol specification to comply with the
1144 changes now made. It is still though a bit outdated.
1146 * The JOIN notify type now takes one extra argument <Channel ID>.
1147 The packet used to be destined to the channel but now the
1148 JOIN type may be sent as list thus it is impossible to
1149 destine it to any specific channel. By adding this argument
1150 it is again possible.
1152 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added CREDITS file. The CHANGES and CREDITS file will appear
1155 in the distribution as well.
1157 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1160 types in the server's silcd/packet_receive.c.
1162 * Implemented CMODE and CUMODE to work in router environment.
1164 * Fixed minor encoding and decoding buglet from the
1165 lib/silccore/silcmode.c.
1167 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1170 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1172 * Changed all SilcConfigServer* and silc_config_server* to
1173 SilcServerConfig* and silc_server_config*, respectively.
1176 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Associated the ID (client or server ID) to the Authentication
1179 Payload to avoid any possibility of forging. Updated the
1180 protocol specification and the code accordingly.
1182 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * The RSA key length is now save to the RsaKey context in the
1185 key generation process in lib/silccrypt/rsa.c. The key length
1186 is now used to figure out the maximum size of the block allowed
1187 to be encrypted/signed.
1189 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1190 is equivalent to the silc_mp_mp2bin but does not allocate any
1193 * Changed silc_mp_mp2bin API to take length argument. If it is
1194 non-zero then the buffer is allocated that large. If zero, then
1195 the size is approximated using silc_mp_sizeinbase, which however
1198 * Created Global RNG API which is global RNG that application can
1199 initialize. After initializing, any routine anywhere in the
1200 code (including library) can use RNG without allocating a new
1201 RNG object. This was done to allow this sort of use of the
1202 RNG in code that has no chance to allocate RNG object. All
1203 applications currently allocate this and many routines in the
1204 library use this. Affected file lib/silccrypt/silcrng.[ch].
1206 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1207 it to use the Global RNG API.
1209 * Defined Authentication Payload into protocol specification that
1210 is used during SILC session to authenticate entities. It is
1211 used for example by client to authenticate itself to the server
1212 to obtain server operator privileges.
1214 Implemented this payload into the lib/silccore/silcauth.[ch].
1215 Implemented also routines for public key based authentication
1216 as the new protocol specification dictates.
1218 Moved definitions of different authentication methods from
1219 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1221 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1222 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1223 silc_pkcs_verify_with_hash functions into the file
1224 lib/silccrypt/silcpkcs.[ch].
1226 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * The client entry's userinfo pointer must be always valid.
1229 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1230 will fail since it requires the userinfo. Now, the userinfo
1231 is allocated as "" if actual userinfo does not exist. Actually,
1232 it must exist and it is totally Ok to drop client connections
1233 that does not announce the userinfo. However, we will make
1234 this workaround for now.
1236 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1237 to return the remote port by socket.
1239 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1242 SILC_SERVER_PENDING_EXEC and added an new macro
1243 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1244 data or when error occurs while processing the pending command.
1246 Added new argument `destructor' into silc_server_command_pending
1247 and to the SilcServerCommandPending object. This destructor is
1248 now called after calling the pending callback or if error occurs
1249 immediately. If error occurs the actual pending callback won't
1250 be called at all - only the destructor. The destructor may be
1251 NULL if destructor is not needed.
1253 All this applies for client library code as well. Similar
1254 changes were made there as well for the pending commands.
1256 In the client, the application must now allocate the
1257 SilcClientCommandContext with the silc_client_command_alloc
1260 * Added reference counter to the SilcServerCommandContext. Added
1261 function silc_server_command_alloc and silc_server_command_dup
1264 Same type of functions added to the client library for the same
1267 * Removed the cmd_ident from IDListData away since it is now
1268 global for all connections. It is the command identifier used
1269 in command sending and with pending commands. The affected file
1272 * Added reference counter to the SilcSocketConnection objecet to
1273 indicate the usage count of the object. The object won't be
1274 freed untill the reference counter hits zero. Currently only
1275 server uses this, and client ignores it. The client must be
1276 set to use this too later. The affected files are
1277 lib/silccore/silcsockconn.[ch]. Added also the function
1278 silc_socket_dup to increase the reference counter.
1280 This was mainly added because it is possible that the socket
1281 is removed underneath of pending command or other async
1282 operation. Now it won't be free'd and proper DISCONNECTING
1283 flags, etc. can be set to avoid sending data to connection that
1284 is not valid anymore.
1286 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1287 the connection. After that it sets SILC_SET_DISCONNECTED.
1288 It is, however, possible that the socket data is not still freed.
1289 The silc_server_packet_process now checks that data is not
1290 read or written to connection that is DISCONNECTED. The socket
1291 get's freed when the reference counter hits zero.
1293 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Changed the client operation API: channel_message operation's
1296 `sender' is now the client entry of the sender, not the nickname
1297 and the `channel' is the channel entry, not the channel name.
1299 In the private_message operation the `sender' is now also the
1300 client entry of the sender not the nickname.
1302 Affected file is lib/silcclient/ops.h and all applications
1303 using the client operations.
1305 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Moved the calling of ops->connect() from connect_to_server_final
1308 into receive_new_id functin since that is the point when the
1309 client is actually allowed to send traffic to network. The
1310 affected file is lib/silcclient/client.c.
1312 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1315 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1316 (if needs broadcasting) instead of broadcasting the packets one
1317 by one which would make a burst in the network traffic.
1319 * Added `broadcast' argument to the functions in silcd/server.[ch]
1320 silc_server_create_new_channel[_with_id] to indicate whether
1321 to send New Channel packet to primary router.
1323 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1325 * Added new function into the silcd/server.[ch] files:
1326 silc_server_create_new_channel_with_id to create new channel with
1327 already existing Channel ID.
1329 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1330 lib/silccore/silcpacket.h. This packet is used t send list of
1331 Set Mode payloads inside one packet. Server uses this to set
1332 the modes for the channels and clients on those channels, that it
1333 announced to the router when it connected to it. The protocol
1334 specification has been updated accordingly.
1336 * The silc_server_new_channel did not handle the packet coming
1337 from normal server as it normally does not send that. However,
1338 when it announces its channels it does send it. Implemented
1339 the support for that.
1341 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1342 into the file lib/silccore/id.h.
1344 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Fixed memory leaks in the functions silc_idlist_del_client,
1347 silc_idlist_del_channel and silc_idlist_del_server in the file
1348 silcd/idlist.c. All of those leaked like a sieve.
1350 * Fixed some small memory leaks in the client's function
1351 silc_client_notify_by_server.
1353 * Added functions into silcd/server.c: silc_server_announce_clients,
1354 silc_server_announce_channels and silc_server_announce_server.
1355 These functions are used by normal and router server to announce
1356 to its primary router about clients, channels and servers (when
1357 router) that we own. This is done after we've connected to the
1360 These functions effectively implements the following packet types:
1361 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1362 and SILC_PACKET_NEW_ID_LIST.
1364 * Added new functions into the silcd/packet_receive.[ch]:
1365 silc_server_new_id_list, silc_server_new_channel_list and
1366 silc_server_new_channel_user_list to handle the incoming
1367 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1369 * Added support of changing Channel ID in the function
1370 silc_server_replace_id. If the server that announces a channel
1371 to the router already exists in the router (with same name but
1372 with different Channel ID), router is responsible to send
1373 Replace ID packet to the server and force the server to change
1374 the Channel ID to the one router has.
1376 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1377 client that the Channel ID has been changed by the router. The
1378 normal server sends this to the client. Client must start using
1379 the new Channel ID as the channel's ID.
1381 Implemented handling of this new type into lib/silcclient/client.c
1382 into the function silc_client_notify_by_server.
1384 * Added new function silc_idlist_replace_channel_id into the files
1385 silcd/idlist.[ch] to replace the Channel ID.
1387 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Call silc_server_command_identify_check always when processing
1390 the IDENTIFY command in silcd/command.c
1392 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1395 send keepalive packets. The packet can be sent by clients,
1396 servers and routers.
1398 Added function silc_socket_set_heartbeat into the file
1399 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1400 If not set, the heartbeat is not performed. The actual
1401 heartbeat is implemented in the low level socket connection
1402 library. However, application is responsible of actually
1405 Added silc_server_send_heartbeat to send the actual heartbeat
1406 packet into silcd/packet_send.[ch]. Server now performs
1407 keepalive with all connections.
1409 * Added silc_task_get_first function into lib/silcutil/silctask.c
1410 to return the timeout task with shortest timeout. There was a bug
1411 in task unregistration that caused problems. TODO has been
1412 updated to include that task system must be rewritten.
1414 * The client library will now resolve the client information when
1415 receiving JOIN notify from server for client that we know but
1416 have incomplete information.
1418 * Rewrote parts of silc_server_remove_from_channels and
1419 silc_server_remove_from_one_channel as they did not remove the
1420 channel in some circumstances even though they should've.
1422 * Encryption problem encountered in server:
1424 The LEAVE command used to send the Channel Key packet to the
1425 router immediately after generating it. However, the code
1426 had earlier sent Remove Channel user packet but not immediately,
1427 ie. it was put to queue. The order of packets in the router
1428 was that Channel Key packet was first and Remove Channel User
1429 packet was second, even though they were encrypted in the
1430 reverse order. For this reason, MAC check failed. Now, this
1431 is fixed by not sending the Channel Key packet immediately but
1432 putting it to queue. However, this is more fundamental problem:
1433 packets that are in queue should actually not be encrypted
1434 because packets that are sent immediately gets encrypted
1435 actually with wrong IV (and thus MAC check fails). So, packets
1436 that are in queue should be encrypted when they are sent to
1437 the wire and not when they put to the queue.
1439 However, the problem is that the current system has not been
1440 designed to work that way. Instead, the packet is encrypted
1441 as soon as possible and left to the queue. The queue is then
1442 just purged into wire. There won't be any fixes for this
1443 any time soon. So, the current semantic for packet sending
1446 o If you send packet to remote host and do not force the send
1447 (the packet will be in queue) then all subsequent packets to the
1448 same remote host must also be put to the queue. Only after the
1449 queue has been purged is it safe again to force the packet
1452 o If you send all packets immediately then it safe to send
1453 any of subsequent packets through the queue, however, after
1454 the first packet is put to queue then any subsequent packets
1455 must also be put to the queue.
1457 Follow these rules and everything works fine.
1459 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Added new function silc_server_remove_clients_by_server to
1462 remove all client entries from ID list when the server connection
1463 is lost. In this case it is also important to invalidate all
1464 client entires as they hold the invalid server entry. This
1465 fixes fatal bug when server has lost connection and will reconnect
1468 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Made some sanity checks to silc_server_daemonise like to check
1471 whether the requested user and group actually exists.
1473 * Added sanity check to SKE's silc_ske_responder_finish to check
1474 that the public and private key actually is valid.
1476 * Invalidate the client's nickname when receiving Replace ID
1477 packet and the Client ID is being replaced. This means that the
1478 server will query the nickname if someone needs it (client)
1481 * Sort the ID Cache in client library when the ID Cache data
1482 has changed (needs sorting).
1484 * Do not allow for SILC client to create several connections to
1485 several servers. The client does not support windows right now
1486 and generating multiple connections causes weird behaviour.
1488 Irssi-silc client does support windows and can handle several
1489 connections without problems, see: www.irssi.org and SILC plugin.
1491 * Fixed some places where client was added to the IDList. The
1492 rule of thumb is following (in order to get everything right):
1493 If the client is directly connected local client then the
1494 `connection' argument must be set and `router' argument must be
1495 NULL to silc_idlist_add_client function. If the client is not
1496 directly connected client then the `router' argument must
1497 bet set and the `connection' argument must be NULL to the
1498 silc_idlist_add_client function.
1500 * The funtion silc_server_packet_send_local_channel actually did
1501 not check whether the client was locally connected or not. It
1502 does that now. Fixed a bug related to LEAVE command.
1504 * Fixed Remove Channel User payload parsing bug in server's
1505 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1507 * The server's silc_server_save_channel_key now checks also the
1508 global ID list for the channel as it might not be in the local
1509 list. Fixed a bug related to LEAVE command.
1511 * Is this the end of the [<unknown>] buglet that has been lurking
1512 around for a long time? A little for loop fix in server's
1513 silc_server_command_whois_parse that is used by both IDENTIFY
1514 and WHOIS command. At least, this was a clear bug and a cause
1515 of one type of [<unknown>] buglet.
1517 * WHOIS and IDENTIFY commands call the function
1518 silc_server_command_[whois/identify]_check function even if
1519 we are not router server.
1521 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Added --with-gmp configuration option. If set the GMP
1524 is always compiled in the SILC source tree. If not set then
1525 it is checked whether the system has the GMP3 installed. If
1526 it has then the GMP won't be compiled (the system's headers
1527 and library is used), if it doesn't have it then the GMP is
1528 compiled in the SILC source tree.
1530 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Changed RSA private exponent generation to what PKCS #1
1533 suggests. We try to find the smallest possible d by doing
1534 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1535 not security fix but optimization.
1537 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1539 * Added new config entry [Identity] to fork the server and run
1540 it as specific user and group. A patch from Bostik.
1542 * Imported Dotconf configuration library into lib/dotconf.
1543 This will be used to create the SILC configuration files later.
1544 It will appear in the distsribution after this commit.
1546 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1548 * A big code auditing weekend happening. Auditing code for
1549 obvious mistakes, bugs and errors. Also, removing any code
1552 Removed files for being obsolete:
1554 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1555 inline in the file lib/silcutil/silcbuffer.h)
1557 o lib/silcutil/silcbufutil.c (the header has inline versions)
1559 Changed code to fix possible error conditions:
1561 o The buffer formatting routines now check that the destination
1562 buffer really has enough space to add the data. This applies for
1563 both buffer formatting and unformatting
1564 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1565 unformatting was changed to accomodate following rules:
1566 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1567 sent to the function while XXX_*STRING will not allocate or copy
1568 the data into the buffer. Instead it sets the pointer from the
1569 buffer into the pointer sent as argument (XXX_*STRING used to
1570 require that the pointer must be allocated already). This change
1571 makes this whole thing a bit more consistent and more optimized
1572 (note that the data returned in the unformatting with XXX_*STRING
1573 must not be freed now). The routines return now -1 on error.
1575 o Tried to find all code that use buffer_format and buffer_unformat
1576 and added return value checking to prevent formatting and
1577 especially unformatting errors and possible subsequent fatal
1580 o Changed ske->x and ske->KEY to mallocated pointers in
1581 lib/silcske/silcske.h. Fixed possible data and memory leak.
1583 o Added return value checking to all *_parse* functions. Fixed
1584 many memory leaks as well.
1586 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1587 so that buffer overflows would not happen. All code now also
1588 checks the return value as it can fail.
1590 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * Added reconnection support to server if the normal server looses
1593 its connection to the router (for example if router is rebooted).
1594 The server performs normal reconnection strategy implemented
1595 to the server. Affected file silcd/server.c.
1597 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Added new packet type SILC_PACKET_SET_MODE that is used to
1600 distribute the information about changed modes (for clients,
1601 channels and clients channel modes) to all routers in the
1602 network. Updated the protocol specification accordingly.
1604 Added functions into silcd/packet_send.c and
1605 silcd/packet_receive.c: silc_server_send_set_mode,
1606 silc_server_set_mode.
1608 Added new files silcmode.[ch] into lib/silccore that implements
1609 the encoding and decoding of Set Mode Payload. Added new type
1610 SilcSetModePayload. Moved the definitions of different modes
1611 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1613 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Oops, a little mistake in server's connection authentication
1616 protocol. The protocol is not ended with FAILURE but with
1617 SUCCESS if the authentication is Ok. :) Affected file is
1620 * Implemented NICK_CHANGE notify handling in server in the file
1621 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1622 the local clients on the channel. After the changing nickname
1623 in router environment snhould work and the [<unknown>] nickname
1624 should appear no more.
1626 The silc_server_replace_id function that receives the Replace ID
1627 payload now sends the NICK_CHANGE notify type also in the file
1628 silcd/packet_receive.c
1630 * Changed WHOIS and IDENTIFY command to support the maximum amount
1631 of arguments defined in protocol specs (3328 arguments). This
1632 fixed a bug that caused problems when there were more than three
1635 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Added extra parameter, command identifier, to the
1638 silc_client_send_command so that explicit command identifier
1641 Changed that ID list routines uses specific command identifier
1642 when sending WHOIS/IDENTIFY requests to the server so that they
1643 can be identified when the reply comes back.
1645 Affected files lib/silcclient/command.[ch],
1646 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1648 * Added `sender' argument to silc_server_packet_send_to_channel
1649 to indicaet the sender who originally sent the packet to us
1650 that we are now re-sending. Ignored if NULL. Affected file
1651 silcd/packet_send.[ch].
1653 * Added some server statistics support in silcd/server_internal.h
1654 SilcServerStatistics structure and around the server code. Also
1655 send some nice statistics information when client is connecting
1658 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Fixed channel ID decoding in server's JOIN command reply in
1661 silcd/command_reply.c
1663 * Fixed braodcasting of replace ID payload to not to send it if
1664 we are standalone server in silcd/packet_receive.c.
1666 * Fixed all channel message sending routines to not to send
1667 packets to clients that has router set, since they are routed
1668 separately in the same function earlier. Affects file
1669 silcd/packet_send.c and all channel packet sending functions.
1671 * In USERS reply, res_argv[i] are not allocated, the table
1672 is allocated. Thus changed that free the table, not its
1675 * In server's whois_check and identify_check if the client is
1676 locally connected do not send any WHOIS commands - they are not
1679 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Fixed some minor bugs in client when sending WHOIS command. The
1682 arguments was in wrong order.
1684 * Removed statis function add_to_channel from server in
1685 silcd/command.c that was previously used with the joining but
1688 * Tested USERS command in router environment successfully with two
1689 routers, two servers and two clients.
1691 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Reorganized the USERS command and command reply in client library
1694 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1695 When the command is given by user we register a pending command
1696 callback that will reprocess the command after the reply has been
1697 received from the server. When reprocessing the packet we then
1698 display the information. Thus, the USERS information is displayed
1699 now in the command callback instead of in the command reply
1700 callback. The processing of the command is same as previously
1701 when server has sent the command reply in the JOINing process.
1703 * Added to USERS command in silcd/command_reply.c to join the client,
1704 we didn't use to know about, to the channel after we've created
1705 a client entry for it. Also, for clienet we did know already still
1706 check whether it is on the channel or not and add it if not.
1708 * Removed silc_server_command_join_notify as the function and its
1711 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Changed the client's pending command handling to the same as the
1714 server's pending command handling. It is also now possible to
1715 execute command reply functions from other command reply
1716 function as the function callbacks for commands and command
1717 replies are one and same. The pending commands are not static
1718 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1719 in client connection context. Thus, pending commands are server
1720 connection specific as it is convenient.
1722 Changed the function silc_client_command_pending and
1723 silc_client_command_pending_del and added new function
1724 silc_client_command_pending_check. Removed the
1725 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1728 * Added cmd_ident, current command identifier, to the client
1729 connection context in lib/silcclient/client.h to keep track on
1730 command identifiers used in command sending. Client's command reply
1731 function handling now supports the mandatory command identifiers.
1733 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1734 funtions in client to fully support pending command callbacks.
1736 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1737 as one of the arguments to the application in the command reply
1740 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1741 before first releasing SILC but came back. Now it is removed again
1742 and should come back nomore. The FORWARDED flag was used only
1743 by the JOINing procedure by forwarding the command packet to router.
1744 Now, the JOINing procedure has been changed to more generic (due
1745 to various router environment issues) and FORWARDED is not needed
1746 anymore for anything. The protocol specification is yet to be
1749 Now, removed silc_server_packet_forward from server and the flag
1750 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1752 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Renamed NAMES command to USERS command. The NAMES was named that
1755 due to historical reasons. Now it is renamed. Also, rewrote
1756 parts of the USERS command. The nickname list is not sent anymore
1757 by the server. Only Client ID and mode lists are sent in the USERS
1758 command. Changed this also to the protocol specification.
1760 The client now resolves the names and stuff after it receives
1761 the USERS list from the server when joining to the channel.
1763 * WHOIS and IDENTIFY commands has been changed to support multiple
1764 Client ID's per command. One can now search for multiple users
1765 in the network by sending only one WHOIS or IDENTIFY command.
1766 Changed the code and the protocol specifications.
1768 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1769 uses silc_server_command_whois_parse to parse the request. */
1771 * If normal server, do not parse the WHOIS and IDENTIFY requests
1772 before sending it to the router. Saves some time.
1774 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Fixed JOIN command on client library. Wrong number of arguments
1777 used to crash the client.
1779 * Added silc_server_channel_has_global function to check whether
1780 channel has global users or not.
1782 * Added silc_server_channel_has_local function to check whether channel
1783 has locally connected clients on the channel.
1785 * The silc_server_remove_from_one_channel now checks whether the
1786 channel has global users or not after given client was removed from
1787 the channel. It also checks whether the channel has local clients
1788 on the channel anymore. If it does not have then the channel entry
1789 is removed as it is not needed anymore.
1791 * The silc_server_notify now checks on JOIN notify whether the joining
1792 client is one of locally connected or global. If it is global then
1793 the channel has now global users on the channel and that is marked
1794 to the channel entry. Also, it now saves the global client to
1795 global list who is joining and JOINs it to the channel. This is
1796 for normal server, that is.
1798 Changed silc_server_send_notify_on_channel,
1799 silc_server_packet_relay_to_channel and
1800 silc_server_packet_send_to_channel check if we are normal server
1801 and client has router set (ie. global client) do not send the
1802 message to that client, as it is already routed to our router.
1804 * Implemented LEAVE notify type handling in silc_server_notify
1807 * Tested LEAVE command in router environment successfully. Tested
1808 with two routers, two servers and two clients.
1812 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1814 * Implemented SIGNOFF notify type handling in silc_server_notify
1817 * silc_server_remove_id now removes the client entry from all channels
1818 it has joined and thusly sends SIGNOFF notify type.
1820 * Rewrote the NAMES list generation in server by removing two excess
1821 loops. The lists are created now inside one loop.
1823 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * silc_server_remove_channel_user checks now also global list
1826 for channel and client.
1828 * silc_server_new_channel_user checks now both local and global
1829 list for channel and client. Fixed a bug in client id decoding.
1830 Used to decode wrong buffer.
1832 * silc_server_channel_message checks now both local and global
1833 list for channel entry.
1835 * Tested channel joining (hence JOIN) in router environment
1836 successfully. Tested with two routers, two servers and two
1839 * Tested channel message sending in router environment successfully.
1841 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Added silc_server_save_channel_key into server.[ch] to save the
1844 received channel key in Channel Key payload processing. It is
1845 also used in JOIN command reply handling.
1847 Equivalent function silc_client_save_channel_key added into
1848 client.[ch] into client library.
1850 * Changed JOIN command reply to send information whether the channel
1851 was created or not (is existing already) and the channel key
1852 payload. Changed protocol specs accordingly.
1854 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1855 the request was sent by ID and not by nickname. Crashed on
1858 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1861 now correctly save the received data.
1863 * silc_server_free_sock_user_data now notifies routers in the
1864 network about entities leaving the network.
1866 At the same time implemented functions silc_server_remove_id
1867 and silc_server_send_remove_id to receive and send REMOVE_ID
1868 packets. The packet is used to notify routers in the network
1869 about leaving entities. The ID removed will become invalid in
1872 * Added function silc_idlist_del_server into server. Removes and
1873 free's server entry from ID list.
1875 * silc_server_private_message function now checks, if we are router,
1876 that the destination ID really is valid ID, naturally.
1878 * In router when NEW_ID packet is received (for new client) the
1879 hash of the Client ID is saved in the ID Cache but the
1880 client->nickname is set to NULL, instead of putting the hash
1883 IDENTIFY command now also checks that client->nickname must be
1884 valid. If it is not if will request the data from the server who
1885 owns the client. Added new function
1886 silc_server_command_identify_check.
1888 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1889 to set the command to already allocated Command Payload.
1891 * Tested private message sending in router environment with two
1892 routers, two servers and two clients. Fixed minor bugs and now
1895 * Fixed segfault from client's NAMES command. Used to crash if
1898 * Forwarded packets must not be routed even if it is not destined
1899 to the receiver. Changed server code comply with this.
1901 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Added `require_reverse_mapping' boolean value to ServerParams
1904 structure. If TRUE (not default) the server will require that
1905 the connecting host has fully qualified domain name.
1907 If the reverse mapping is not required and hostname could not be
1908 found the IP address is used as hostname.
1910 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Implemented version string checking to both client and server.
1913 The check is incomplete currently due to the abnormal version
1914 strings used in development version of SILC.
1916 * Changed all command functions in server to use the new
1919 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Changed char *data to unsigned char *data in ID Cache system to
1922 support binary data as ID Cache data. Changed code to support
1923 binary data in lib/silccore/idcache.c.
1925 * Renamed silc_server_packet_relay_command_reply to
1926 silc_server_command_reply as it is normal packet receiving
1927 function. Rewrote the function to accept command replys for
1928 servers and not only for clients.
1930 * Mark remote router always as registered server if we are connecting
1931 to it. Otherwise, commands sent by the router to us are ignored.
1933 * All ID List find routines now returns the ID Cache Entry pointer
1934 as well if requested.
1936 * WHOIS command works now in router environment, tested with two
1937 routers, two servers and two clients.
1939 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1940 in router environment (as it is almost equivalent to WHOIS) but
1941 hasn't been tested thoroughly. Added new functions:
1943 silc_server_command_identify_parse
1944 silc_server_command_identify_send_reply
1945 silc_server_command_identify_from_client
1946 silc_server_command_identify_from_server
1948 * Disabled route cache adding because adding two different ID's with
1949 same IP replaces the old cache entry thus giving wrong route.
1950 The entry->router->connection is always the fastest route anyway
1951 so route cache may not be needed. Of course, new routes maybe
1952 established after receiving the ID when the entry->router->connection
1953 might not be anymore the most optimal.
1955 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Add route cache for received ID for fast routing.
1959 * Added silc_server_packet_route to route received packet on router
1960 that is not destined to us.
1962 * Renamed silc_server_get_route to silc_server_route_get.
1964 * Added id_string and id_string_len fields into SilcServer to
1965 include encoded ServerID for fast comparing without excess
1966 encoding of the ID's.
1968 * Cleaned up WHOIS command on server side. Added following static
1971 silc_server_command_whois_parse
1972 silc_server_command_whois_check
1973 silc_server_command_whois_send_reply
1974 silc_server_command_whois_from_client
1975 silc_server_command_whois_from_server
1977 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1978 arguments in command replies. All command functions should be
1979 updated to use this macro.
1981 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Minor typo fixes on command reply handling on server.
1985 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Added silc_server_command_add_to_channel internal routine to add
1988 the client to the channel after router has created the channel and
1989 sent command reply to the server.
1991 * Added generic silc_server_send_command to send any command from
1994 * Use static buffer with ID rendering instead of duplicating data.
1996 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1998 * Fixed a channel user mode bug when joining to a channel server gave
1999 everybody channel founder rights, oops.
2001 * We mark ourselves as the router of the incoming server connection
2002 if we are router ourselves. This way we can check in some packet
2003 sending functions whether it is locally connected server. For
2004 incoming router connections we put NULL.
2006 * For router sending packets locally means now always sending the
2007 packet cell wide; to local clients and local servers. For normal
2008 server sending packet locally means sending it to only local
2011 * Fixed the JOIN command to really work in router environment. If the
2012 channel is created it is always created by the router. Router is
2013 also responsible of making the initial joining to the channel,
2014 sending JOIN notify to the sending server and distributing
2015 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2016 does not exist server doesn't do anything else but forward the
2017 command to the router which performs everything.
2019 * Added silc_server_send_channel_key function to send the Channel Key
2022 * Added silc_server_create_channel_key to create new channel key. The
2023 channel key is now re-generated everytime someone joins or leaves
2024 a channel, as protocol dictates. Note: channel->key_len is the
2027 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2030 packet_receive.[ch] to separate packet sending and receiving
2031 routines. The server.[ch] now includes everything else including
2032 actual packet processing (writing and reading data) and other
2035 Renamed silc_server_private_message_send_internal to
2036 silc_server_send_private_message. The routine is still though
2037 used only to relay private messages as server does not send
2038 private messages itself.
2040 Renamed silc_server_new_channel to silc_server_create_new_channel
2041 and added new function sicl_server_new_channel that handles the
2042 incoming New Channel packet. Added also new sending function
2043 silc_server_send_new_channel to send New Channel Payload.
2045 * Added new function silc_server_notify to process incoming notify
2046 packet to the server/router. Server may then relay the notify
2047 to clients if needed.
2049 * Added new function silc_server_new_channel_user to process incoming
2050 New Channel User packet. Router will redistribute the packet and
2051 send JOIN notify to its local clients and locally connected servers
2052 if needed. Normal server will send JOIN notify to its local client
2053 on same channel when received this packet. Added also corresponding
2054 sending function silc_server_send_new_channel_user to sent the
2057 * Added boolean route argument to send_notif_to_channel and
2058 packet_send_to_channel functions to attempt to route the packet
2059 if it is TRUE and send only locally if it is FALSE.
2061 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * silc_server_replace_id now broadcasts the received replace ID
2064 packet if it is not broadcast packet already. The router must
2065 broadcast to inform other routers about changed ID.
2067 * Added backpointer to server's router into SilcServer context in
2068 silcd/server_internal.h.
2070 * Fixed silc_server_packet_broadcast to send correct broadcast
2073 * The channel key is now distributed to the local client as soon
2074 as it is received from the router (in router environment) so that
2075 no other packet may be sent for the channel until client has
2078 * silc_server_remove_channel_user now broadcasts the received
2079 Remove Channel User packet if it is not broadcast packet already.
2080 The router must broadcast to inform other routers about removed
2083 * Added users field into SilcPacketContext that is a reference count
2084 of the context. One can increase the reference count by calling
2085 silc_packet_context_dup which is now changed to just increase the
2086 reference count instead of duplicating the data. The reference
2087 count is decresed by calling silc_packet_context_free that will
2088 free the data after the reference count hits zero.
2090 For now on the packet context and everything allocated into it
2091 (including the raw packet from network) must be freed by calling
2092 the new silc_packet_context_free function. Added also new function
2093 silc_packet_context_alloc that must be used now to allocate the
2094 context. This also means that if a routine is asynchronous from
2095 silc_[client/server]_packet_parse_type the packet context must
2096 be duplicated by calling silc_packet_context_dup. Otherwise it
2097 gets free'd after silc_[client/server]_packet_parse_type returns.
2098 Also, one must remember that if packet is duplicated then its
2099 reference count must be decresed by calling the free function as
2100 many times as it was duplicated.
2102 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2103 from both client and server.
2105 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Made joining to a channel working in router environment.
2109 * Cleaned up JOIN command on server side and create function
2110 silc_server_command_join_channel internal routine to make the
2113 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Changed silc_command_pending list to SilcDList. Also, added
2116 `ident' field to SilcServerCommandPending structure to identify
2117 the reply and to call correct callback.
2119 Added silc_server_command_pending_check function to replace the
2120 corresnponding macro. The silc_command_pending list is not
2123 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2124 to set identifier to previously allocated Command Payload. It
2125 is used to set identifier for command when resending Command
2128 * Added silc_command_payload_encode_payload to encode Command
2129 Payload buffer from SilcCommandPayload structure.
2131 * Added silc_argument_payload_encode_payload to encode Argument
2132 payload buffer from SilcArgumentPayload structure.
2134 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Changed WHOIS command to support router connection on server side.
2137 The whois request is always sent to router unless the server is
2138 standalone server. After server has received the reply from the
2139 router will it send the reply to the client.
2141 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2142 broadcast received broadcast packet. The function is used only
2143 by router. The broadcast packet is always sent to the router's
2146 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2147 render given ID to printable string, for log files for example.
2149 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Made basic router to router connections working. At least they
2152 can now connect to each other but nothing really works the way
2153 they are supposed - yet.
2155 * Added new initiator token to RouterConnection configuration
2156 file in silcd/serverconfig.[ch]. It is used to tell whether we
2157 are the initiator to the remote router or whether we'll expect
2158 the other end to connect.
2160 * Moved registering of listener task to silc_server_init, hence
2161 the server starts listenning as soon as it is run, even if it
2162 does not have connections to other routers. Let's see how well
2165 * Changed default connection retry timeouts for more suitable in
2168 * Removed cipher and such arguments from silc_idlist_add_client
2169 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2170 Added new function silc_idlist_add_data to add the keys and stuff
2173 * Added SilcIDListData structure and added it to SilcClientEntry
2174 and SilcServerEntry as their first field in the structure. This
2175 way we can explicitly cast the ID entries to the SilcIDListData
2176 structure and get common data for the entries. In past, we had
2177 to first check what type of connection it is and then cast it to
2178 correct ID entry type. Now, we can directly cast the opaque
2179 pointer to the SilcIDListData (no matter what ID entry it actually
2180 is) and get the data needed.
2182 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2185 in some circumstances even if threre were timeout tasks, though not
2186 IO tasks, but tasks anyway. Now fixed.
2188 * Defined SilcServerConnection structure to hold connection specific
2189 stuff about directly connected servers and routers. The definition
2190 is currently in silcd/server_internal.h. I thought about having
2191 a bit more important role fro this struct but for now it is used
2192 only when connecting to other server (or router actually).
2194 * Added connecting retry support in server when connecting to
2195 router(s). The retry feature implement exponential backoff
2196 algorithm. Also, added SilcServerParams structure to hold default
2197 parameters for server. For now, it include these retry settings
2198 and are hard coded. After server is moded to be as Silc Server
2199 Library this structure will be more important.
2201 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Changed client librarys channel->clients table to SilcList and
2204 changed code accordingly.
2206 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Changed client's channel table to SilcList and changed code
2209 accordingly. Also changed SilcChannelClientEntry to include back-
2210 pointer to the channel so that client entry can use that structure
2211 as list as well and we have fast cross-reference to the channel.
2212 This change dramatically decreased the complexity of channel
2213 handling with client entry and vice versa (removed one extra
2214 loop when searching for channel entry from many functions).
2216 * Changed server->sim from table to SilcDList and changed code
2219 * NAMES command can now be used from user interface. It will show
2220 the user list on the channel, neatly.
2222 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2223 Code now saves realname of the user if it becomes available.
2225 * Renamed configure.in to configure.in.pre and made ./prepare
2226 script to automatically add correct version string to
2227 configure.in which it creates from configure.in.pre.
2229 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * NAMES command reply now shows users mode with the nickname when
2234 * Moved silc_client_ch[u]mode[_char] functions from
2235 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2236 place sucks, they are utility functions and should be in some
2239 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2241 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2244 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2248 * Added TRQ (efficient deque and list library) into lib/trq. This is
2249 a very good list library that is currently used in the SILC. Defined
2250 SilcList API over the library because I didn't like the API very
2251 much. See lib/trq/silclist.h for the API and examples of how to
2252 use the API. Fixed various places in the code to use the new
2253 SilcList API. The SilcList is meant for lists that has a structure
2254 already defined as a list. It is not suitable to add just some
2255 context to the list (in TRQ, the context is the list actually).
2257 So, I defined SilcDList that can be used for the purpose where
2258 predefined list structure does not exit. This can be used as
2259 such list. Now some context just can be added to the SilcDList.
2260 Currently this list is not used in the SILC just yet, though there
2261 are a lot places where this can replace dynamically allocated
2262 tables and I will fix these places, later, to use SilcDList.
2263 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2264 and use TRQ internally).
2266 Also fixed some annoying warning messages that the original TRQ
2267 code generated. Also minor changes to TRQ's Makefile.in.
2269 * Added support for querying by Client ID to both WHOIS and
2270 IDENTIFY commands into server, as required by the protocol.
2272 * Removed method function pointers from SilcBuffer structure. They
2273 weren't used to anything and just increased the context size for
2274 no good reason. This change also made silc_buffer_alloc and
2275 silc_buffer_free functions inline functions.
2277 * Disabled command flooding detection support until it's fixed so
2278 that it accepts commands in but does not execute them more than once
2281 * Added silc_net_localhost(), to return local hostname, into
2282 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2283 that must be initialized before calling silc_client_init.
2285 * Added new function: silc_server_send_notify_on_channels to send
2286 notify messages to all channels client has joined. It is assured
2287 that the message is sent only once per client.
2289 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2290 lib/silcutil/silcutil.[ch] as silc_format function. The new
2291 function is generic and is used by server as well, not only by
2292 the logging routines.
2294 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2295 the provided version string was not acceptable. Added new function:
2296 silc_ske_check_version into lib/silcske/silcske.h. The function
2297 must be implemented by the application (client or server) and it
2298 does not reside in the SKE library. The function checks the version
2299 string remote end sent.
2301 * Added back pointers (to opaque context and to SilcSocketConnection)
2302 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2304 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2305 duplicate packet context structure.
2307 * Changed `notify' client operation to send same arguments as client
2308 receives from server except for ID's. ID's are mapped to correct
2309 ID entry and that is returned. Also, if channel entry is not sent
2310 by server but the notify is for channel the channel entry is sent
2311 to application (otherwise application doesn't know that it is for
2312 channel (library gets it from packet's Destination ID)).
2314 * Added silc_client_remove_from_channels into client library to
2315 remove a client from all channels it has joined to. Used when
2316 received SIGNOFF notify from server. Added also new function
2317 silc_client_replace_from_channels to replace old ID entry with
2318 new ID entry on all channels. Used when received NICK_CHANGE
2321 * Fixed ID Cache list handling in silc_idlist_get_client in
2322 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2323 to get (or query) client by ID.
2325 * Updated TODO list.
2327 * Added connection authentication status message defined by the
2328 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2329 support for these into the code in client and server side.
2331 * Added generic function silc_client_send_command to send any command
2332 with variable argument list. Application should use this function
2333 to send commands if the command functions provided by the library
2334 does not suite for the application's user interface needs.
2336 * Added new `failure' client operation. Application is notified about
2337 received failure packet if client is executing a protocol. In this
2338 case the protocol's execution has failed.
2340 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2341 is required by the protocol.
2343 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2344 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2347 * Added status flag to SilcSKE object to indicate realtime status
2348 of the SKE protocol.
2350 * Application receives now exactly same command reply arguments as
2351 the library receives from server. However, if ID is received the
2352 corresponding ID entry is returned to the application (eg. Client
2353 ID is mapped to correct SilcClientEntry entry and that is returned).
2354 Changed command_reply client operation due to this change.
2356 * Changed all ID's in commands and in command replys as ID Payloads.
2357 Change affected both client and server side codes.
2359 All ID's sent in SILC network (with execption of ID's in SILC
2360 Packet header) are sent in ID Payload to support variable length
2363 * Server now notifies nick changes and notifies all clients on
2364 the channels about the new nickname (about the new Client ID,
2367 * Implemented CMODE command to change channel modes. Supports all
2368 channel modes defined by the protocol specs except ban and invite
2369 lists. (Also, private channel key mode is supported but support for
2370 setting private channel key in client is missing, thus, this mode
2371 has no effect on client side (except that server requires that the
2372 client uses private channel key and normal channel traffic does not
2375 Also, invite mode works per se, but INVITE command does not work
2376 yet correctly, so you can set channel as invite only channel but
2377 inviting clients to the channel does not work (it is yet to be
2378 thought what's the best way to do it).
2380 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2381 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2382 Implemented CUMODE command to change user's mode on the channel.
2383 Supports all modes defined by the protocol specs.
2385 * Added NAMES command reply to return users modes on the channel.
2387 * Removed unnecessary and slow ciphers from lib/silccrypt.
2389 * Set SO_KEEPALIVE option to connection sockets by default.
2391 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2393 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2394 redefined the Notify Payload into protocol specs.
2396 * Added silc_id_payload_parse_id to get ID directly from raw
2399 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2402 accept searching by Client ID as well.
2404 * Added support for LEAVE and SIGNOFF notify types in client library.
2406 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2407 to parse ID Payload from raw data.
2409 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Added flags parameter into silc_ske_assemble_security_properties
2412 function in lib/silcske/silcske.[ch].
2414 * Changed notify client operation to fit better for notify messages
2415 sent by server. The notify payload received from server is now
2416 passed to the application (after parsing it to SilcNotifyPayload).
2417 It is application's responsibility to retrieve the arguments
2418 from the payload and show the message the way it wants. The message
2419 sent by server is implementation specific.
2421 * Changed public keys to comply with the protocol specification.
2422 Old public keys are not supported anymore and are not compatible.
2424 * Removed nickname from Channel Payload as the latest draft removed
2425 it. The client must resolve the nickname from the NAMES command
2426 reply received when it joined the channel.
2428 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2430 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Fixed some errors in protocol specification drafts.
2434 * Created lib/silccore/silcnotify.c to implement Notify Payload
2435 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2436 generic payloads described by protocol specifications. The file
2437 includes implementations for ID Payload and Argument Payload.
2439 * Changed Command Payload implementation to use the new Argument
2440 Payload. Changed command_xxxx_payload to command_payload_xxxx
2441 to comply with SILC coding conventions.
2443 * Added suppport for Argument Payload handling in Notify Payload
2444 implementation as protocol requires it. Added the new support
2445 into server and client lib as well.
2447 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Added support for multiple nicknames on same channel. [n] is
2450 added locally to the nickname if there are more than one same
2451 nicknames on the channel.
2453 * Server now sends all nicknames that matched WHOIS request.
2454 Client also shows the list received from server.
2456 * Added TOPIC command to client side. User can now set and show
2457 current topic on channel.
2459 * Added MOTD command to client and server. Also, server sends the
2460 motd when client connects to the server.
2462 * Changed version strings to comply ISO 8601.
2464 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Fixed protocol error handling in client library. It should now
2467 cope even if the SKE fails for some reason.
2469 * Made new protocol specification drafts for submitting to IETF.
2471 * Implemented TOPIC command to server in silcd/command.c.
2473 * Added two new notify types into lib/silccore/silcnotify.h:
2474 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2475 notify nickname change and topic setting/change on a channel.
2477 * API change of command_reply operation in client library. The
2478 application gets now the status type received from server as well.
2480 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2482 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2484 * Cras fixed and optimized the packet handling even further and
2485 it should work now. Minor change to the prototype of function
2486 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2488 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Added new function into lib/silcutil/silcschedule.[ch]:
2491 silc_schedule_with_fd to select() a specified fd. The function
2492 returns after timeout expires or data arrives or goes. The
2493 function is used by packet routines to wait that all data is
2494 received from network.
2496 * Fixed data reading from network in lib/silccore/silcpacket.c.
2497 The code now assures that all data is read from the fd and then
2498 continues packet processing. This was a bug fix since the code
2499 used to drop some data in some circumstances.
2501 * Added new function into lib/silcclient/client.[ch]:
2502 silc_client_start_key_exchange to start key exchange after
2503 connection has been established to server. The code internally
2504 now uses this funtion but its main purpose was to provide it
2505 for applications that perform their own connecting. After
2506 application has created a connection it merely calls this
2507 function to start the key exchange between client and server.
2508 The library takes care of everything else after that.
2510 Updated also lib/silcclient/README to explain the usage of
2513 * Do not send to application information that connection has
2514 been established. Application gets notified it by connect
2517 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Applied cras's patch to add silc_schedule_one function. The
2520 function runs scheduler once and returns.
2522 * Fixed the scheduler after cras messed it up. The timeout
2523 handling works now as it's supposed to work.
2525 * Added into lib/silccore/ silcnotify.h to include notify
2526 message types support. Changed silc_server_send_notify*
2527 functions, in server.[ch], to support those new notify types.
2528 Added the support for the notify types into client library,
2529 as well. Added new notify client operation into ops.h in
2532 * Changed silc_server_packet_send_to_channel to send normal
2533 packets instead of just channel message packets. The function
2534 is now used to send the notify packets to channels. It is not
2535 used to send channel message packets anymore, as server never
2538 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2539 va_arg()s as it seems to require it nowadays. I guess, if SILC
2540 is compiled with older va_arg() the new code should work anyway.
2542 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Splitted core library. Core library (lib/silccore) includes
2545 now only SILC protocol specific core (and common) components.
2546 Created new utility library (lib/silcutil) that includes more
2547 generic purpose stuff. The stuff for util library was taken
2548 from the old core library. This was minor and easy split.
2550 * Created SILC Client Library (lib/silcclient) that includes
2551 implementation of the SILC client without user interface. This
2552 was major move from silc/ directory. The code has been changed
2553 so that it is transparent towards the user interface. The
2554 silc/ directory includes now the same user interface as before
2555 and it uses the new client library. Read lib/silcclient/README.
2556 Basicly, the client library performs everything else related
2557 to SILC except user interface handling. Also, configuration
2558 files are considered to be part of user interface and library
2559 does not handle them.
2561 This change also changed a lot of structures, function naming etc.
2562 Most important change was that SilcClientWindow object was
2563 renamed to SilcClientConnection in the client library. Created
2564 also new file lib/silcclient/ops.h. Also added new files
2565 silc/local_command.[ch] and silc/client_ops.[ch].
2567 All these changes were made to make it easier for user interface
2568 designers to create what ever user interface for the SILC client
2571 It is also expected that the server will be moved to lib
2572 directory as well and SILC Server Library will be created;
2573 sometimes in the future.
2575 * Removed Local commands from lib/silccore/silccommand.h as
2576 they are application specific and new client library does not
2577 handle any of those anymore.
2579 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2580 old client implementation in silc/.
2582 * Added support for callback functions in SILC_LOG_* macros.
2583 Application can now set its own callbacks that will be called
2584 instead of using the default functions that will always print
2585 the debug messages to stderr (or stdout). Also, debugging can
2586 now be disabled by setting silc_debug to FALSE and re-enabled by
2587 setting it to TRUE. Note, that logging will still work even
2588 if debugging is disabled.
2590 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2591 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2592 silc_log_reset_debug_callbacks.
2594 * To enable debugging in silc client one must give now -d
2595 option on command line.
2597 * Changed silc_schedule_init to automatically allocate task queues
2598 if they are not allocated before calling it.
2600 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Added GMP 3.1 into math library.
2604 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2607 a channel in SILC network. The packet is used by servers and
2608 routers to notify other routers that user has left a channel.
2609 This little feature was missing until now. Added the feature
2610 to protocol specification as well.
2612 Added functions: silc_server_send_remove_channel_user and
2613 silc_server_remove_channel_user into server.[ch].
2615 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2616 lib/silccore/silcpacket.h. However, they are not implemented
2619 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Fixed joining to a channel and sending channel messages
2622 between server and router. The channel message sending should
2623 now work inside a cell.
2625 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Fixed the private message sending between server and router.
2628 The private message sending should now work inside a cell.
2630 * Added silc_server_replace_id into server.[ch] to replace
2631 existing ID in the SILC network.
2633 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2634 and silc_idlist_replace_server_id into idlist.[ch] in server.
2636 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Fixed the server to server connections. Server can again now
2639 connect to router. Router to router connections probably does
2642 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added dynamic protocol registering support. Now protocols can
2645 registered and unregistered on the fly. Patch by cras.
2647 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Added lib/contrib directory to hold routines that some platforms
2650 don't have but are needed by SILC.
2652 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2653 into lin/contrib to provide getopt() and getopt_long() for
2654 those who don't have it.
2656 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Added AWAY command to client. When away message is set and
2659 client receives a private message packet the client automatically
2660 replies to the sender with the away message.
2662 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2663 bug seemed to be the cause of recent problems when compiling
2666 * Added version detection support to SKE protocol specification
2667 and added the new changes to the SKE implementation as well.
2668 There were other minor changes in the SKE protocol as well.
2670 Many changes in lib/silcske/silcske.[ch] and in
2671 lib/silcske/payload.[ch].
2673 * Added ^U functionality, clear input line. Patch from cras.
2675 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Mainly small bugfixes on core library. Fixed some debugging
2678 logging and buffer overflow in silclog.c.
2680 * Updated config.sub and config.guess on the distribution tree.
2682 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Added command lagging support in server. Client may execute
2685 commands now only once in two seconds.
2687 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Optimized packet reception. MAC computation and checking is now
2690 also more optimized. A lot previously duplicated code is now
2691 used as generic by both client and server.
2693 * Fixed key pair generation in clientutil.c
2695 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Added into lib/silccore/silcbufutil.[ch] new function;
2698 silc_buffer_realloc.
2700 * Moved generic packet sending/encryption functions to
2701 lib/silccore/silcpacket.[ch] from client and server. Some
2702 rewriting of the functions.
2704 * Moved all generic packet reception/decryption functions to
2705 lib/silccore/silcpacket.[ch] from client and server. The
2706 packet processing is now much cleaner in both client and server.
2707 These were major changes in both client and server.
2709 * Created many common functions in server to do packet sending.
2710 Previously code were duplicated a lot, this has been removed
2713 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Rewrote major parts of the ID cache system. Don't know
2716 whether it is better now or not but at least the API is more
2719 * Major rewrite on ID cache stuff on client because of the ID
2720 cache API changes. Added idlist.c to client.
2722 * Also major rewrite on ID cache stuff on server as well.
2723 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2724 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2725 in hand, instead they are all put into the ID cache system now.
2726 All server_idlist_* routines uses ID cache now instead of
2727 traversing its own lists (those lists does not exist anymore).
2728 SilcIDList though still exists. Also, SilcXXXEntry's are
2731 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Finally made the SKE implementation compliant to the protocol
2734 specification. All mp integers are now binary encoded as
2735 opposed being HEX encoded.
2737 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2740 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2741 functions: silc_[encode/decode]_pem. Also added function
2742 silc_encode_pem_file to PEM encode with newlines ('\n') for
2745 * SILC public keys are now encoded either PEM or binary. Same
2746 option is for private keys as well. By default private keys
2747 are binary encoded and public keys PEM encoded. Silly HEX
2748 encoding were removed.
2750 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2751 function to create fingerprints.
2753 * Fixed a bug in SHA1; does not change the original data anymore.
2755 * Partly implemented INFO command on client and server side.
2756 Fixed CLEAR command. Changes to SERVER command; show current
2757 server(s) when giving command without arguments. Added
2758 VERSION command to client.
2760 * Added check to server that unregistered connections cannot
2761 execute commands (unless it is specificly allowed).
2763 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Fixed screen refresh.
2767 * Fixed channel joining bug from client. On some circumstances
2768 client tried to join to a channel it had already joined.
2770 * Added public key verification process into client's protocol.c.
2771 The client now verifies the public key from user and saves
2772 it into ~./silc/serverkeys/ directory.
2774 Added into: clientutil.[ch]: silc_client_verify_server_key.
2776 * Changed SKE protocol's silc_ske_initiator_finish function
2777 to accept callback function that verifies the received public
2778 key. Removed old silc_ske_verify_public_key function.
2780 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2783 silc_pkcs_private_key[_data]_set.
2785 * Made the password and public authentication more cleaner in
2786 server's protocol.c.
2788 * Removed historic and obsolete protocol `channel_auth' from
2789 both client and server.
2791 * Removed wrong way of sending command status messages from
2792 server to client in server's command.c. The old way violated
2793 protocol specification.
2795 Changes to silccore/silccommand.[ch]: removed
2796 silc_command_encode_status_payload -> not needed anymore,
2797 changed silc_command_encode_payload_va to accept extra
2798 argument on variable argument list. The argument type must
2799 now be provided to the function. Also, added new function:
2800 silc_command_encode_reply_payload_va which is same as
