1 Fri Mar 30 13:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the WHOIS and IDENTIFY send reply function to really
4 check whether to send list or just one entry. Affected file
7 * Cleaned up the LEAVE command's channel key distribution. The
8 affected file silcd/command.c.
10 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
13 crashed since it did not handle the fact that there is no cipher
14 called "3" and didn't check the error condition. Now fixed.
16 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
17 flag. It can be used to send message requests.
19 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Implemented the RESTART command in the client.
23 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
24 notice type messages. Added notice printing to the user
27 * The channel keys are not re-generated if the channel's mode
28 is PRIVKEY, ie private key on the channel exists. Affected
29 files silcd/server.c and silcd/command.c.
31 * Fixed a little bug in channel message delivery when channel
32 private keys are set in the server. Affected file is
35 * Changed the setting on channel->on_channel = TRUE from the
36 silc_client_save_channel_key to the JOIN command reply. The
37 key payload is not received if the private channel key is set.
38 Affected file lib/silcclient/command_reply.c and the
39 lib/silcclient/client_channel.c.
41 * When the CMODE_CHANGE notify is sent and the channel private
42 key mode is removed the channel key must be re-generated in
43 other cells as well. Added this support for the router in the
44 silcd/packet_receive.c.
46 * Added new local command NOTICE to send notice message on
47 channel. Affected file silc/local_command.[ch].
49 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Added new local command ME to the client. It is used to send
52 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
53 some action. Affected file silc/local_command.[ch].
55 * Changed channel_message and private_message client operations
56 to deliver the message flags to the application. Added also
57 the `flags' arguments to the silc_client_send_channel_message
58 and silc_client_send_private_message functions. Affected file
61 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Redefined the Private Message Payload to support private message
64 keys and to support the new private message flags. Updated
65 the protocol specs. Flags makes it possible to have for example
68 * Added new type SilcPrivateMessagePayload and defined an API
69 for it in the lib/silcclient/silcprivate.[ch].
71 * Tested private message private keys successfully. Tested the
72 private message key set, unset and list commands with the new
75 * Redefined the Channel Message Payload to include the channel
76 message flags (equal with private message flags) to support
77 for example CTCP style messages.
79 * Defined some of the message (for channel and private message)
80 flags. Updated the protocol specs and added the flags to the
81 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
83 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Added SilcKeyAgreementStatus type to the key agreement routines
86 to indicate the current status and error if one occured.
87 The status types are defined in the lib/silcclient/silcapi.h.
89 * Added new local command KEY that is used to set and unset private
90 keys for channels, set and unset private keys for private messages
91 with remote clients and to send key agreement requests and
92 negotiate the key agreement protocol with remote client. The
93 key agreement is supported only to negotiate private message keys,
94 it currently cannot be used to negotiate private keys for channels,
95 as it is not convenient for that purpose.
97 * Fixed a minor pending callback setting bug in the function
98 silc_client_get_client_by_id_resolve, now the function works.
99 Affected file lib/silcclient/idlist.c.
101 * Added function silc_net_get_local_port to get local bound
102 port by socket. Added to lib/silcutil/silcnet.[ch].
104 * Added `sockets' and `sockets_count' fields to the SilcClient
105 object. They hold the sockets of the listenning sockets in
106 the client. Listenning sockets may be for example the key
107 agreement server. Affected file lib/silcclient/client.[ch].
108 Added functions the silc_client_add_socket and the
109 silc_client_del_socket. They are exported to the application
112 * Added ~./silc/clientkeys to support other client's public keys.
114 * Renamed verify_server_key client operation to verify_public_key
115 and added one argument to indicate the type of the connection
116 (server, client etc.).
118 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Added silc_server_connection_auth_request to handle the
121 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
122 silcd/packet_receive.[ch].
124 * Added silc_server_send_connection_auth_request into the
125 silcd/packet_send.c to send the connection auth request packet.
127 * Cleaned up the silcd/protocol.c a bit and fixed some memory
130 * Fixed the public key authentication in responder side in the
131 server. The `auth_data' pointer includes the SilcPublicKey
132 not the path to the public key. Affected file silcd/protocol.c.
134 * Implemented the public key authentication in the initiator side
135 in the server. Affected file silcd/protocol.c.
137 * Removed the [RedirectClient] config section from the server
138 configuration. Is not needed and I don't want to implement it.
140 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * Cleaned up the CMODE command in the server. It now works
143 correctly and supports all the modes defined in the protocol.
144 Affected file is silcd/command.c.
146 * Added `hmac_name' field to the SilcChannelEntry in the server
147 to hold the default HMAC of the channel. It can be set when
148 creating the channel (with JOIN command). Affected files
151 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
152 type to indicate the change of the current cipher and hmac
153 on the channel. Client can safely ignore the <cipher> argument
154 (if it chooses to do so) since the CHANNEL_KEY packet will
155 force the channel key change anyway. The <hmac> argument is
156 important since the client is responsible of setting the new
157 HMAC and the hmac key into use.
159 * Fixed the CMODE command in the client library as well.
161 * Tested CMODE command in router environment successfully.
163 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Show the version of the remote client (or server) when connecting
166 to the server. It is logged to the log file. Affected file
169 * Fixed the KILLED notify handling in the client library. The
170 client must be removed from all channels when receiving the
173 Also, do not remove the client entry when giving the KILL
174 command but when the KILLED notify is received.
176 * Removed silc_idlist_find_client_by_nickname from the server.
177 Not needed anymore. Affected files silcd/idlist.[ch].
179 * Implemented the CHANNEL_CHANGE notify type handling to the
180 server. Affected file silcd/server.c.
184 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

198 * Added function silc_server_get_client_resolve to find the
199 client entry by ID from all ID lists and then resolve it
200 (using WHOIS) if it cannot be found. Affected file is
203 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Implemented the BAN command to the client library.
207 * The JOIN command in the server now checks the invite list
210 * Changed the silc_command_reply_payload_encode_va and the
211 silc_command_payload_encode_va to support that if argument is
212 NULL it ignores and checks the next argument. Affected file
213 lib/silccore/silccommand.c.
215 * Added silc_server_send_notify_ban to send the BAN notify
216 type between routers.
218 * Chaned the silc_notify_payload_encode to support that if
219 argument is NULL it ignores and checks the next argument.
220 Affected file lib/silccore/silcnotify.c.
222 * Tested ban lists in router environment successfully.
224 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Implemented BAN command to the server, in silcd/command.[ch].
228 * Removed the BAN and INVITE_LIST modes from the CMODE command
231 * Added function silc_string_match to regex match two strings.
232 Affected files lib/silcutil/silcutil.[ch].
234 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Redefined parts of the SilcChannelEntry in the server to support
237 the new ban and invite lists.
239 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * Redefined the INVITE command. The same command can be used to
242 invite individuals to the channel but also to manage the invite
243 list of the channel (to add to and remove from the invite list).
244 Updated the protocol specs.
246 * Added new command SILC_COMMAND_BAN that can be used to manage
247 the ban list of the channel. Updated the protocol specs.
249 * Removed the channel modes: the SILC_CMODE_BAN and the
250 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
251 in the CMODE command. The equivalent features are now available
252 using INVITE and BAN commands. Updated the protocol specs.
254 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
255 in the network about change in the current ban list. The notify
256 type is not used by the client.
258 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
259 support the invite lists.
261 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Added new function silc_string_regexify that converts string
264 including wildcard characters into regex string that can
265 be used by the GNU regex library. Added into the file
266 lib/silcutil/silcutil.[ch].
268 Added silc_string_regex_combine to combine to regex strings
269 into one so that they can be used as one regex string by
270 the GNU regex library. Added into the file
271 lib/silcutil/silcutil.[ch].
273 Added silc_string_regex_match to match two strings. It returns
274 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
276 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Imported GNU regex to the soruce tree into lib/contrib.
279 Fixed some compiler warning from the regex.c.
281 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Fixed MOTD command in the server to work in router environment.
285 * Fixed the MOTD command in the client library to support
286 the server argument in the command.
288 * Added `nickname_len' argument to the silc_idlist_add_client
289 in the server, as the `nickname' argument may be binary data
292 * Added silc_idlist_get_channels to return all channels from
295 * Implemented LIST command to the server. Affected file is
298 * Implemented the LIST command to the client library and on the
301 * Added [<user count>] argument to the LIST command reply.
302 With private channels the user count is not shown.
304 * Updated TODO and README.
306 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * The client entry's data.registered must be TRUE even with
309 global client entry on global client list. The data.registered
310 is used to check whether the client is anymore in the network,
311 for example with WHOWAS command so it must be valid.
313 * Fixed the WHOWAS command in the server. It now actually works
314 in router environment. Added function into silcd/command_reply.c
315 silc_server_command_reply_whowas_save.
317 * Added silc_idlist_purge function to the silcd/idlist.c
318 to periodically purge the ID Cache.
320 * Fixed INFO command in the server. It works now in router
321 environment. Added <server name> argument to the INFO command
322 reply. Updated the protocol specs.
324 * Fixed minor bug in silc_idcache_purge to not purge if the
325 expire value is zero.
327 * Fixed various bugs in WHOIS and IDENTIFY command handling as
328 they were buggy because of the WHOWAS information.
330 * Fixed local command MSG to handle the async resolving of
331 the remote client properly. It used to fail the first MSG.
332 Affected file silc/local_command.c.
334 * Added `data_len' field to SilcIDCache context.
336 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
338 * Update TODO. Todo in commands in the server.
340 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
343 used by routers as broadcast packet to inform other routers
344 about the changed user mode.
346 Implemented the notify handling in the server. Affected file is
347 silcd/packet_receive.c. Added the function
348 silc_server_send_notify_umode to the silcd/packet_send.[ch].
350 * Added new generic Channel Payload and deprecated the New Channel
351 Payload. The New Channel Payload is now the generic Channel
354 * Added new argument `mode' to the silc_server_send_new_channel
355 as it is required in the Channel Payload now.
357 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
358 and created a new and real SilChannelPayload to represent the
359 new generic Channel Payload. Implemented the encode/decode
360 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
362 * Added silc_server_get_client_channel_list to return the list
363 of channels the client has joined for WHOIS command reply.
364 Affected file silcd/server.[ch].
366 * Implemented the channel list sending in the WHOIS command reply
367 in server and in the client.
369 Implemented the channel list displaying on the user interface
370 as well. Affected file silc/client_ops.c.
372 * Added silc_channel_payload_parse_list to parse list of Channel
373 Payloads. It returns SilcDList list of SilcChannelPayloads.
374 Client for example can use this function to parse the list of
375 channels it receives in the WHOIS command reply. The caller
376 must free the list by calling silc_channel_payload_list_free.
377 Affected files lib/silccore/silcchannel.[ch].
379 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Added one new argument <user mode> to the WHOIS command reply
382 to return the mode of the user in SILC. Updated the protocol
385 Implemented it to the server and client.
387 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Fixed the mode printing on the user interface on joining.
390 Affected file silc/client_ops.c.
392 * Implemented the UMODE command and user modes in general to the
393 client library and to the user interface.
395 * Implemented the UMODE command to the server.
397 * The server now sends UNKNOWN_COMMAND error status if client sends
398 unknown command. Affected file silcd/command.c.
400 * All server commands now handle the command identifier the right
401 way when sending the command reply to the client. The client can
402 use to identify the command replies with the identifier.
404 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Added silc_server_get_client_route to resolve the route to
407 the client indicated by the client ID. Affected file is
410 * Added silc_server_relay_packet as general function to relay
411 packet to arbitrary destination. This deprecates functions
412 like _send_private_message_key, _relay_notify etc. Affected
413 file is silcd/packet_send.[ch].
415 Removed silc_server_send_key_agreement,
416 silc_server_send_private_message_key and
417 silc_server_packet_relay_notify functions from the file
418 silcd/packet_send.[ch].
422 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
423 server. Affected file silcd/packet_receive.[ch].
425 * Implemented the KILL command to the client. Implemented the
426 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
427 Affected files lib/silcclient/command[_reply].c and
428 lib/silcclient/client_notify.c. Implemented the KILL notify
429 printing in the user inteface.
431 * Fixed a lot silc_parse_nick memory leaks from the client
432 library in the file lib/silcclient/command.c.
434 * Changed the silc_server_send_notify_on_channels's `sender'
435 argument from SilcSocketConnection to SilcClientEntry to
436 check the sender as entry and not as connection object and not
437 to send to the client provided as argument. The affected file
438 is silcd/packet_send.[ch].
440 * The notify packets that are destined directly to the client used
441 to not to be processed by the server. Now changed that and the
442 server processes all notify packets. After relaying the packet
443 to the client the notify packet is processed in the server.
445 * The silc_server_free_client_data now checks whether there is
446 pending outgoing traffic for the client and purges the data to
447 the network before removing the client entry.
449 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
452 an client is killed from the SILC Network. Updated the protocol
455 Added new function silc_server_send_notify_killed to the
456 silcd/packet_send.[ch].
458 * Added function silc_server_packet_relay_notify to relay notify
459 packets that are destined directly to a client. In this case
460 the server does not process the notify packets but merely relays
461 it to the client. Affected file silcd/packet_send.[ch].
463 Added also silc_server_packet_process_relay_notify to check
464 whereto relay the notify. Affected file is
465 silcd/packet_receive.[ch].
467 * Implemented the KILL command to the server.
471 * Added the backup schema desgined last fall to the protocol
472 specs for everyone to see. The specification is in the
473 *-spec-xx.txt draft and the packet type definitions for the
474 backup routers is in *-pp-xx.txt draft. Thusly, added also
475 new packet type SILC_PACKET_CELL_ROUTERS.
477 * A big security problem in the implementation discovered. The
478 signoff of an client did not cause new channel key generation
479 which it of course should've done. The channel keys must be
480 always re-generated when client leaves (or signoffs) the channel.
481 The silc_server_remove_from_channels funtion now handles
482 the channel key re-generation.
484 * Added `sender' argument to the silc_server_send_notify_on_channels
485 to not to send the client provided as argument. Affected file
486 silcd/packet_send.[ch].
488 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Implemented OPER and SILCOPER commands into the server and
493 * Added silc_auth_verify and silc_auth_verify_data to verify
494 the authentication directly from the authentication payload.
495 It supports verifying both passphrase and public key based
496 authentication. Affected file lib/silccore/silcauth.[ch].
498 * Added `hash' field to the SilcIDListData structure. It is the
499 hash negotiated in the SKE protocol. Affected file is
502 * Slight redesigning of the SilcAuthPayload handling routines.
503 Do not send SilcPKCS but SilcPublicKey as argument.
505 * Implemented the public key authentication support to the
506 serverconfig. The public key is loaded from the provided path
507 and saved as authentication data to void * pointer. Thus,
508 changed the unsigned char *auth_data to void *auth_data;
510 * Fixed SHUTDOWN command to send the reply before the server
511 is shutdown. :) Affected file silcd/command.c.
513 * Fixed fatal bug in CONNECT command. The hostname was invalid
514 memory and server crashed. Affected file silcd/command.c.
516 * Fixed fatal bug in CLOSE command. The server_entry became
517 invalid but was referenced later in the command. Affected file
520 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Fixed fatal bug in failure packet handling. Server ignored
523 the failure and thus crashed when it came.
527 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
530 that the command may be executed only once in (about) 2 seconds.
531 The old SILC_CF_LAG flag is same but allows command bursts up
532 to five before limiting.
534 Added the support for CF_LAG and CF_LAG_STRICT flags to the
535 server code. Various commands now includes the CF_LAG_STRICT
536 flag to disallow any kind of miss-use of the command.
538 * Fixed the silc_buffer_unformat to not to allocate any data
539 if the length of the data is zero. It used to allocate the
540 length + 1. Affected file lib/silcutil/silcbuffmt.c.
542 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Changed the format of AdminConnection configuration section
545 in the server. Added username of the admin to the format.
546 Affected files silcd/serverconfig.[ch].
548 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
549 to return admin configuration data by host, username and/or
552 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Implemented WHOWAS command to the server. Added the functions:
556 silc_server_command_whowas_parse,
557 silc_server_command_whowas_send_reply,
558 silc_server_command_whowas_from_client and
559 silc_server_command_whowas_from_server
561 * Added <Client ID> argument to the WHOWAS command reply. Updated
562 the protocol specs accordingly.
564 * Implemented WHOWAS command and command_reply to the client
567 Implemented the WHOWAS printing on the user interface.
569 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Added new argument to the WHOWAS command reply, the real name.
572 It is an optional argument. Updated the protocol specs.
574 * Added SilcIDCacheDestructor callback that is registered when
575 the SilcIDCache is allocated. The callback is called when
576 an cache entry in the ID Cache expires, or is purged from the
577 cache. Added into lib/silccore/idcache.[ch].
579 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
580 to destruct the client entries when the cache entry expires.
581 Other ID Cache's in server and in the client library ignores
584 * If the ID Cache entry's `expire' field is zero then the entry
585 never expires. Added boolean `expire' argument to the
586 silc_idcache_add function in the lib/silccore/idcache.[ch].
587 If it is TRUE the default expiry value is used.
589 * Added silc_server_free_client_data_timeout that is registered
590 when client disconnects. By default for 5 minutes we preserve
591 the client entry for history - for WHOWAS command.
593 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Added support to the server to enforce that commands are not
596 executed more than once in 2 seconds. If server receives
597 commands from client more frequently, timeout is registered
598 to process the commands. Affected file silcd/command.c.
599 Added new function silc_server_command_process_timeout.
601 * Changed NICK_NOTIFY handling in client library to check that
602 if the client's nickname was changed, so there is no need to
603 resolve anything from the server.
605 * Removed error printing from the WHOIS and IDENTIFY commands.
606 If error occurs then it is ignored silently in the client library.
607 The application, however, may map the received error to
608 human readable error string. The application currently maps
609 the NO_SUCH_NICKNAME error to string.
611 * Made the command status message public to the application. Moved
612 them from lib/silcclient/command_reply.c to
613 lib/silcclient/command_reply.h. The application can map the
614 received command status to the string with the
615 silc_client_command_status_message function.
617 * Added check to the server to check that client's ID is same
618 as the Source ID in the packet the client sent. They must
621 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Added dist-bzip hook to the Makefile.am to make bzip2
624 compressed distributions.
626 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Server now enforces the maximum length for the nickname and
629 the channel as protocol specification dictates. 128 bytes for
630 nickname and 256 bytes for channel name.
632 * Moved the WHOIS printing to the application. The client libary
633 does not print out the WHOIS information anymore, the application
634 must do it. Renamed silc_client_command_reply_whois_print to
635 the silc_client_command_reply_whois_save.
637 The client's idle time is also sent to the application now, and
638 the idle is shown on screen.
640 * Added silc_client_command_reply_identify_save to save the
641 received IDENTIFY entries.
643 * Do not check for channel private keys in message sending and
644 reception if the channel does not have the PRIVKEY mode set.
645 Affected file lib/silclient/client_channel.c.
647 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
650 just surfaced after chaning the JOIN procedure.
652 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Added silc_client_get_clients_by_list to get client entries
655 from Client ID list, that is returned for example by JOIN
656 and USERS command replies. The application should use this
657 function for example when JOIN command reply is received to
658 resolve the clients already on the channel (library does not
659 do that anymore as USERS command reply is not used in the JOIN
660 procedure anymore). Affected files lib/silcclient/silcapi.h and
661 lib/silcclient/idlist.c.
663 * JOIN command reply and USERS command reply returns now SilcBuffer
664 pointers instead of unsigned char pointers when returning
665 the client list and mode list.
667 * Added <Client ID> argument to the JOIN command reply, mainly
668 for the server to identify for which client the command was
669 originally sent. Updated protocol specs accordingly.
671 * Added SilcDlist private_key pointer to the SilcChannelEntry
672 in the client to support the channel private keys. Affected
673 file is lib/silcclient/idlist.h.
675 * Added SilcChannelPrivateKey argument to the function
676 silc_client_send_channel_message so that application can choose
677 to use specific private ke if it wants to. If it is not provided,
678 the normal channel key is used, unless private keys are set.
679 In this case the first (key that was added first) is used
680 as the encryption key.
682 * Implemented the support for channel private key handling.
683 Implemented the following functions:
685 silc_client_add_channel_private_key,
686 silc_client_del_channel_private_keys,
687 silc_client_del_channel_private_key,
688 silc_client_list_channel_private_keys and
689 silc_client_free_channel_private_keys
691 Affected file lib/silcclient/client_channel.c.
693 * Added the support for the private keys in the channel message
694 sending and encryption and in the message reception and
695 decryption. Affected funtions are
696 silc_client_send_channel_message and silc_client_channel_message.
698 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Added SKE's key verify callback to the client library's
701 KE protocol context. Affected files lib/silcclient/protocol.[ch].
703 * Removed the statement that server (or router) must send USERS
704 command reply when joining to the channel so that the client
705 knows who are on the channel. Instead, the client list and
706 client's mode list is now sent in the JOIN command reply to the
707 client who joined channel. This is better solution.
709 * Added function silc_server_get_users_on_channel and function
710 silc_server_save_users_on_channel to the silcd/server.[ch].
712 * Removed function silc_server_command_send_users from the
715 * Do not show topic on the client library anymore. The topic is
716 sent in the command reply notify to the application and the
717 application must show the topic now.
719 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Added client searching by nickname hash into the IDENTIFY and
722 WHOIS commands in the server as they were clearly missing from
723 them. Affected file is silcd/command.c.
725 * Fixed a bug in private message receiving in the client library.
726 The remote ID was freed and it wasn't supposed, now it is
729 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Minor fix to the channel payload; allocate the data area, as it
732 needs to be of specific length.
734 * If the key agreement port is zero then the operating
735 system will define the bound port. Affected files are
736 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
738 * Added new function silc_channel_payload_decrypt into the file
739 lib/silccore/silcchannel.[ch].
741 * Moved the channel message etc, check from silc_packet_decrypt
742 to applications. The library calls now a generic
743 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
744 when the packet is either normal or special. This was done to
745 allow more wide range of checking that was not allowed when
746 the code was in library. Now applications can do virtually any
747 checks to the packet and return to the library the decision how
748 the packet should be processed. Affected files are
749 lib/silccore/silcpacket.[ch].
751 Added silc_server_packet_decrypt_check to the server and
752 silc_client_packet_decrypt_check to the client library.
754 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
755 to send with specified source and destination information.
757 * Channel message delivery between routers was broken after the
758 channel key distribution was fixed earlier. The channel key
759 was used be to distributed to other routers as well which is not
760 allowed by the protocol. Now this is fixed and channel keys
761 really are cell specific and the channel message delivery between
762 routers comply with the protocol specification.
764 * Fixed various commands in server to check also the global list
765 for the channel entry and not just the local list. The affected
766 file silcd/command.c.
768 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Added assert()s to buffer formatting and unformatting routines
771 to assert (if --enable-debug) when error occurs. Affected
772 file: lib/silcutil/silcbuffmt.c.
774 * Changed to auto-reconnect to check whether the remote host is
775 router and register the re-connect timeout if it is. It used
776 to check that whether we are normal server, but router must do
777 auto-reconnect with another router as well. Affected file
780 * Removed the [<key len>] option from CMODE command as the cipher
781 name decides the key length, nowadays. See the defined ciphers
782 from the protocol specification.
784 * Added [<hmac>] option to the CMODE command to define the HMAC
785 for the channel. Added SILC_CMODE_HMAC channel mode.
787 * Added [<hmac>] option for the JOIN command so that user can
788 select which HMAC is used to compute the MACs of the channel
791 * Added Hmac field to the Channel Message Payload. The integrity
792 of plaintext channel messages are now protected by computing
793 MAC of the message and attaching the MAC to the payload. The
794 MAC is encrypted. Now, it is clear that this causes some
795 overhead to the size of the packet but rationale for this is that
796 now the receiver can verify whether the channel message decrypted
797 correctly and also when private keys are set for the channel the
798 receiver can decrypt the packet with several keys and check from
799 the MAC which key decrypted the message correctly.
801 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
802 lib/silccrypt/silccipher.[ch].
804 * Added silc_hash_len to return the digest length into the
805 lib/silcrypt/silchash.[ch].
807 * Rewrote parts of Silc Channel Payload interface in the
808 lib/silccore/silcchannel.[ch]. The encode function now also
809 encrypts the packet and parse function decrypts it.
811 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
813 * Fixed a minor formatting bug in the SKE's key material processing.
814 It actually might have processed the keys wrong way resulting
817 * Redefined the mandatory HMAC algorithms and added new algorithms.
818 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
819 and hmac-md5 truncated to 96 bits. The mandatory is now
820 hmac-sha1-96. Rest are optional (including the one that used
821 to be mandatory). Rationale for this is that the truncated HMAC
822 length is sufficient from security point of view and can actually
823 make the attack against the HMAC harder. Also, the truncated
824 HMAC causes less overhead to the packets. See the RFC2104 for
827 * Added new [hmac] configuration section. The SKE used to use
828 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
829 is of course wrong. The official names that must be proposed in
830 the SKE are the ones defined in the protocol specification
831 (hmac-sha1-96 for example). The user can configure any hmac
832 using any hash function configured in the [hash] section. At
833 least, the mandatory must be configured.
835 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
837 * Added HMAC list to the SKE proposal list. It has now both
838 hash algorithm list and HMAC list. This makes the protocol
839 incompatible with previous versions. The SKE now seems to work
840 the way it is supposed to work, for the first time actually.
842 * Defined plain Hash algorithms to the protocol specification.
845 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Implemented support for key agreement packets into the server.
848 Added functions silc_server_key_agreement and
849 silc_server_send_key_agreement. Other than these functions,
850 server has nothing to do with this packet.
852 * Added support for private message key packets into the server.
853 Added functions silc_server_private_message_key and
854 silc_server_send_private_message_key.
858 * Changed the silc_[client|server]_protocol_ke_set_keys to be
859 called in the protocol's final callback instead in the END
860 protocol state. This makes a little more sense and in the same
861 time in client we can use the same protocol routines for normal
862 key exchange and to key agreement packet handling as well.
864 * Added to both client's and server's KE protocol context the
865 SilcSKEKeyMaterial pointer to save the key material. We will
866 bring the key material to the protocol's final callback by doing
867 this. The final callback must free the key material.
869 * Added SKE's packet_send callback into client's KE protocol
870 context so that the caller can choose what packet sending function
871 is used. This way we can use different packet sending when
872 doing normal SKE when doing key agreement packet handling (in
873 the key agreement packet handling we do not want to encrypt
876 * Implemented the responder side of the key agreement routines
877 in the client. The client can now bind to specified port and
878 accept incoming key negotiation. The key material is passed
879 to the application after the protocol is over.
881 * Implemented the processing of incoming Key Agreement packet
882 in the client. Added function silc_client_key_agreement to
885 * Implemented the intiator side of the key agreement routines
886 in the client. The client can now initiate key agreement with
887 another remote client. The key material is passed to the
888 application after the protocol is over.
890 * Created client_keyagr.c to include all the key agreement
893 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
894 SILC_TASK_CALLBACK except that it is not static.
896 * Created client_notify.c and moved the Notify packet handling
897 from the client.[ch] into that file.
899 * Created client_prvmsg.c and moved all private message and
900 private message key routines from the client.[ch] into that file.
902 * Create client_channel.c and moved all channel message and
903 channel private key routines from the client.[ch] into that file.
905 * Changed silc_client_get_client_by_id_resolve to resolve with
906 WHOIS command instead of IDENTIFY command, in the file
907 lib/silclient/idlist.c.
909 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Implemented the SKE's responder side to the Client library.
913 * When FAILURE is received to the protocol do not trust it
914 blindly. Register a timeout to wait whether the remote closes
915 the connection as it should do it, only after that process the
916 actual failure. This was changed to both client and server.
918 * Added client_internal.h to include some of the structures
919 there instead of client.h in lib/silcclient/.
921 * Added function silc_task_unregister_by_callback to unregister
922 timeouts by the callback function.
924 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Some "Incomplete WHOIS info" errors has been appearing on the
927 log files. Took away the entry->userinfo check from WHOIS
928 reply sending. The entry->userinfo is now " " if client did not
929 provide one. I thought this was fixed earlier but something
930 is wrong still. Let's see if the error still appears.
932 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Fixed a minor bug in the login when the channel key is
935 re-generated in the server. It used to generate the key in
936 wrong order and thus caused problems in the channel traffic.
938 * Fixed a minor bug in channel key distsribution after
939 KICK command. The key was not sent to the router even though
942 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Added silc_ske_process_key_material_data as generic routine
945 to process any key material as the SILC protocol dictates. The
946 function is used by the actual SKE library but can be used by
947 applications as well. This relates to the private message keys
948 and the channel private keys since they must be processed the
949 same way the normal SILC session keys. The protocol dictates
950 this. Affected files: lib/silcske/silcske.[ch].
952 Added also silc_ske_free_key_material to free the
953 SilcSKEKeyMaterial structure.
955 * Defined silc_cipher_set_key function to set the key for
956 cipher without using the object's method function. The affected
957 files: lib/silccrypt/silccipher.[ch].
959 * Implemented silc silc_client_add_private_message_key,
960 silc_client_add_private_message_key_ske,
961 silc_client_del_private_message_key,
962 silc_client_list_private_message_keys and
963 silc_client_free_private_message_keys functions in the
966 Added functions silc_client_send_private_message_key to send
967 the Private Message Key payload and silc_client_private_message_key
968 to handle incoming Private Message Key payload.
970 * Added Cipher field to the Private Message Key payload to set
971 the cipher to be used. If ignored, the default cipher defined
972 in the SILC protocol (aes-256-cbc) is used.
974 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Removed lib/silcclient/ops.h file.
978 Redefined parts of the SILC Client Library API. Created new
979 file silcapi.h that deprecates the ops.h file and defines the
980 published Client Library API. Defined also private message key
981 API and channel private key API into the file.
983 This is the file that the application must include from the
984 SILC Client Library. Other files need not be included by
985 the application anymore.
987 * Added new key_agreement client operation callback and also
988 defined the Key Agreement library API for the application.
990 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
993 is used by clients to request key negotiation between another
994 client in the SILC network. If the negotiation is started it
995 is performed using the SKE protocol. The result of the
996 negotiation, the secret key material, can be used for example
997 as private message key.
999 Implemented the Key Agreement payload into the files
1000 lib/silccore/silauth.[ch].
1002 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1004 * Redefined ciphers for the SILC protocol. Added some new ciphers
1005 and defined the key lengths for the algorithms. Changed the
1006 code accordingly. The default key length is now 256 bits.
1008 * Fixed SKE key distribution function silc_ske_process_key_material
1009 when the key length is more than 128 bits. The default key
1010 length in SILC is now 256 bits.
1012 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1013 to indicate unsupported algorithm.
1015 * Renamed rijndael.c to aes.c and all functions as well.
1017 * Fixed a long standing channel key setting bug in client library.
1018 Weird that it has never surfaced before.
1020 * Fixed bug in channel deletion. If the entire channel is removed
1021 then it must also delete the references of the channel entry
1022 from the client's channel list as the client's channel entry and
1023 the channel's client entry share same memory.
1025 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Implemented CONNECT and SHUTDOWN commands in the client.
1029 * Implemented CLOSE command to the client.
1031 * Added the function silc_idlist_find_server_by_name into the
1032 files silcd/idlist.[ch].
1034 Added the function silc_idlist_find_server_by_conn into the
1035 files silcd/idlist.[ch].
1037 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * DIE command was renamed to SHUTDOWN. Updated the both code
1042 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1043 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1045 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1048 * Added function silc_server_create_connection function to create
1049 connection to remote router. My server implementation actually
1050 does not allow router to connect to normal server (it expects
1051 that normal server always initiates the connection to the router)
1052 so the CONNECT command is only good for connecting to another
1055 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1058 or some other client was kicked from the channel.
1060 Implemented the handling of the notify type to both client
1063 Implemented silc_server_send_notify_kicked to send the KICKED
1064 notify. It is used to send it to the server's primary router.
1066 * Implemented the KICK command into server and client.
1068 * Added `query' argument to the silc_idlist_get_client function
1069 to indicate whether to query the client from server or not if
1072 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1073 to indicate that the client is not channel founder.
1077 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Removed the rng context from SilcPacketContext structure and
1080 changed that the packet routine uses the Global RNG API.
1082 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1084 * Added support for quit message that client can "leave" on the
1085 channel when it quits the SILC. It is ditributed inside the
1086 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1088 Added silc_server_free_client_data that will take the
1089 signoff message as argument.
1091 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1093 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Updated parts of the protocol specification to keep it up
1098 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1101 payloads in one packet.
1103 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1104 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1105 use now the new List flag.
1107 * Also deprecated the following packet types: REPLACE_ID,
1108 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1110 * Added list support for Notify packet in server.
1112 * Added silc_server_send_notify_channel_change to send the
1113 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1114 the silc_server_send_replace_id.
1116 * Added silc_server_send_notify_nick_change to send the
1117 NICK_CHANGE notify type. Deprecates the function
1118 silc_server_send_replace_id.
1120 * Added silc_server_send_notify_join to send the JOIN notify type.
1121 Deprecates the function silc_server_send_new_channel_user.
1123 * Added silc_server_send_notify_leave to send LEAVE notify type.
1124 Deprecates the function silc_server_send_remove_channel_user.
1126 * Added silc_server_send_notify_cmode and
1127 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1128 types. Deprecates the silc_server_send_set_mode function.
1130 * Added SERVER_SIGNOFF notify type to indicate that server has
1131 quit. This means that all clients on the channel from that
1132 server will drop. This can be also used when netsplit happens.
1134 Deprecated REMOVE_ID packet type since it is not needed anymore
1137 Added silc_server_send_notify_server_signoff to send the
1138 SERVER_SIGNOFF notify type. Deprecates the function
1139 silc_server_send_remove_id.
1141 Added also silc_server_send_notify_signoff to send the
1142 SIGNOFF notify type.
1144 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1145 SILC protocol from this day on. Changed the protocol
1146 specification as well.
1148 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1149 notify type. It is used between routers to notify about
1150 topic changes on a channel.
1152 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1155 * Partly updated the protocol specification to comply with the
1156 changes now made. It is still though a bit outdated.
1158 * The JOIN notify type now takes one extra argument <Channel ID>.
1159 The packet used to be destined to the channel but now the
1160 JOIN type may be sent as list thus it is impossible to
1161 destine it to any specific channel. By adding this argument
1162 it is again possible.
1164 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1166 * Added CREDITS file. The CHANGES and CREDITS file will appear
1167 in the distribution as well.
1169 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1172 types in the server's silcd/packet_receive.c.
1174 * Implemented CMODE and CUMODE to work in router environment.
1176 * Fixed minor encoding and decoding buglet from the
1177 lib/silccore/silcmode.c.
1179 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1182 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1184 * Changed all SilcConfigServer* and silc_config_server* to
1185 SilcServerConfig* and silc_server_config*, respectively.
1188 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Associated the ID (client or server ID) to the Authentication
1191 Payload to avoid any possibility of forging. Updated the
1192 protocol specification and the code accordingly.
1194 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * The RSA key length is now save to the RsaKey context in the
1197 key generation process in lib/silccrypt/rsa.c. The key length
1198 is now used to figure out the maximum size of the block allowed
1199 to be encrypted/signed.
1201 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1202 is equivalent to the silc_mp_mp2bin but does not allocate any
1205 * Changed silc_mp_mp2bin API to take length argument. If it is
1206 non-zero then the buffer is allocated that large. If zero, then
1207 the size is approximated using silc_mp_sizeinbase, which however
1210 * Created Global RNG API which is global RNG that application can
1211 initialize. After initializing, any routine anywhere in the
1212 code (including library) can use RNG without allocating a new
1213 RNG object. This was done to allow this sort of use of the
1214 RNG in code that has no chance to allocate RNG object. All
1215 applications currently allocate this and many routines in the
1216 library use this. Affected file lib/silccrypt/silcrng.[ch].
1218 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1219 it to use the Global RNG API.
1221 * Defined Authentication Payload into protocol specification that
1222 is used during SILC session to authenticate entities. It is
1223 used for example by client to authenticate itself to the server
1224 to obtain server operator privileges.
1226 Implemented this payload into the lib/silccore/silcauth.[ch].
1227 Implemented also routines for public key based authentication
1228 as the new protocol specification dictates.
1230 Moved definitions of different authentication methods from
1231 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1233 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1234 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1235 silc_pkcs_verify_with_hash functions into the file
1236 lib/silccrypt/silcpkcs.[ch].
1238 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * The client entry's userinfo pointer must be always valid.
1241 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1242 will fail since it requires the userinfo. Now, the userinfo
1243 is allocated as "" if actual userinfo does not exist. Actually,
1244 it must exist and it is totally Ok to drop client connections
1245 that does not announce the userinfo. However, we will make
1246 this workaround for now.
1248 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1249 to return the remote port by socket.
1251 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1254 SILC_SERVER_PENDING_EXEC and added an new macro
1255 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1256 data or when error occurs while processing the pending command.
1258 Added new argument `destructor' into silc_server_command_pending
1259 and to the SilcServerCommandPending object. This destructor is
1260 now called after calling the pending callback or if error occurs
1261 immediately. If error occurs the actual pending callback won't
1262 be called at all - only the destructor. The destructor may be
1263 NULL if destructor is not needed.
1265 All this applies for client library code as well. Similar
1266 changes were made there as well for the pending commands.
1268 In the client, the application must now allocate the
1269 SilcClientCommandContext with the silc_client_command_alloc
1272 * Added reference counter to the SilcServerCommandContext. Added
1273 function silc_server_command_alloc and silc_server_command_dup
1276 Same type of functions added to the client library for the same
1279 * Removed the cmd_ident from IDListData away since it is now
1280 global for all connections. It is the command identifier used
1281 in command sending and with pending commands. The affected file
1284 * Added reference counter to the SilcSocketConnection objecet to
1285 indicate the usage count of the object. The object won't be
1286 freed untill the reference counter hits zero. Currently only
1287 server uses this, and client ignores it. The client must be
1288 set to use this too later. The affected files are
1289 lib/silccore/silcsockconn.[ch]. Added also the function
1290 silc_socket_dup to increase the reference counter.
1292 This was mainly added because it is possible that the socket
1293 is removed underneath of pending command or other async
1294 operation. Now it won't be free'd and proper DISCONNECTING
1295 flags, etc. can be set to avoid sending data to connection that
1296 is not valid anymore.
1298 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1299 the connection. After that it sets SILC_SET_DISCONNECTED.
1300 It is, however, possible that the socket data is not still freed.
1301 The silc_server_packet_process now checks that data is not
1302 read or written to connection that is DISCONNECTED. The socket
1303 get's freed when the reference counter hits zero.
1305 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Changed the client operation API: channel_message operation's
1308 `sender' is now the client entry of the sender, not the nickname
1309 and the `channel' is the channel entry, not the channel name.
1311 In the private_message operation the `sender' is now also the
1312 client entry of the sender not the nickname.
1314 Affected file is lib/silcclient/ops.h and all applications
1315 using the client operations.
1317 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Moved the calling of ops->connect() from connect_to_server_final
1320 into receive_new_id functin since that is the point when the
1321 client is actually allowed to send traffic to network. The
1322 affected file is lib/silcclient/client.c.
1324 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1327 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1328 (if needs broadcasting) instead of broadcasting the packets one
1329 by one which would make a burst in the network traffic.
1331 * Added `broadcast' argument to the functions in silcd/server.[ch]
1332 silc_server_create_new_channel[_with_id] to indicate whether
1333 to send New Channel packet to primary router.
1335 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Added new function into the silcd/server.[ch] files:
1338 silc_server_create_new_channel_with_id to create new channel with
1339 already existing Channel ID.
1341 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1342 lib/silccore/silcpacket.h. This packet is used t send list of
1343 Set Mode payloads inside one packet. Server uses this to set
1344 the modes for the channels and clients on those channels, that it
1345 announced to the router when it connected to it. The protocol
1346 specification has been updated accordingly.
1348 * The silc_server_new_channel did not handle the packet coming
1349 from normal server as it normally does not send that. However,
1350 when it announces its channels it does send it. Implemented
1351 the support for that.
1353 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1354 into the file lib/silccore/id.h.
1356 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Fixed memory leaks in the functions silc_idlist_del_client,
1359 silc_idlist_del_channel and silc_idlist_del_server in the file
1360 silcd/idlist.c. All of those leaked like a sieve.
1362 * Fixed some small memory leaks in the client's function
1363 silc_client_notify_by_server.
1365 * Added functions into silcd/server.c: silc_server_announce_clients,
1366 silc_server_announce_channels and silc_server_announce_server.
1367 These functions are used by normal and router server to announce
1368 to its primary router about clients, channels and servers (when
1369 router) that we own. This is done after we've connected to the
1372 These functions effectively implements the following packet types:
1373 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1374 and SILC_PACKET_NEW_ID_LIST.
1376 * Added new functions into the silcd/packet_receive.[ch]:
1377 silc_server_new_id_list, silc_server_new_channel_list and
1378 silc_server_new_channel_user_list to handle the incoming
1379 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1381 * Added support of changing Channel ID in the function
1382 silc_server_replace_id. If the server that announces a channel
1383 to the router already exists in the router (with same name but
1384 with different Channel ID), router is responsible to send
1385 Replace ID packet to the server and force the server to change
1386 the Channel ID to the one router has.
1388 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1389 client that the Channel ID has been changed by the router. The
1390 normal server sends this to the client. Client must start using
1391 the new Channel ID as the channel's ID.
1393 Implemented handling of this new type into lib/silcclient/client.c
1394 into the function silc_client_notify_by_server.
1396 * Added new function silc_idlist_replace_channel_id into the files
1397 silcd/idlist.[ch] to replace the Channel ID.
1399 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1401 * Call silc_server_command_identify_check always when processing
1402 the IDENTIFY command in silcd/command.c
1404 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1406 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1407 send keepalive packets. The packet can be sent by clients,
1408 servers and routers.
1410 Added function silc_socket_set_heartbeat into the file
1411 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1412 If not set, the heartbeat is not performed. The actual
1413 heartbeat is implemented in the low level socket connection
1414 library. However, application is responsible of actually
1417 Added silc_server_send_heartbeat to send the actual heartbeat
1418 packet into silcd/packet_send.[ch]. Server now performs
1419 keepalive with all connections.
1421 * Added silc_task_get_first function into lib/silcutil/silctask.c
1422 to return the timeout task with shortest timeout. There was a bug
1423 in task unregistration that caused problems. TODO has been
1424 updated to include that task system must be rewritten.
1426 * The client library will now resolve the client information when
1427 receiving JOIN notify from server for client that we know but
1428 have incomplete information.
1430 * Rewrote parts of silc_server_remove_from_channels and
1431 silc_server_remove_from_one_channel as they did not remove the
1432 channel in some circumstances even though they should've.
1434 * Encryption problem encountered in server:
1436 The LEAVE command used to send the Channel Key packet to the
1437 router immediately after generating it. However, the code
1438 had earlier sent Remove Channel user packet but not immediately,
1439 ie. it was put to queue. The order of packets in the router
1440 was that Channel Key packet was first and Remove Channel User
1441 packet was second, even though they were encrypted in the
1442 reverse order. For this reason, MAC check failed. Now, this
1443 is fixed by not sending the Channel Key packet immediately but
1444 putting it to queue. However, this is more fundamental problem:
1445 packets that are in queue should actually not be encrypted
1446 because packets that are sent immediately gets encrypted
1447 actually with wrong IV (and thus MAC check fails). So, packets
1448 that are in queue should be encrypted when they are sent to
1449 the wire and not when they put to the queue.
1451 However, the problem is that the current system has not been
1452 designed to work that way. Instead, the packet is encrypted
1453 as soon as possible and left to the queue. The queue is then
1454 just purged into wire. There won't be any fixes for this
1455 any time soon. So, the current semantic for packet sending
1458 o If you send packet to remote host and do not force the send
1459 (the packet will be in queue) then all subsequent packets to the
1460 same remote host must also be put to the queue. Only after the
1461 queue has been purged is it safe again to force the packet
1464 o If you send all packets immediately then it safe to send
1465 any of subsequent packets through the queue, however, after
1466 the first packet is put to queue then any subsequent packets
1467 must also be put to the queue.
1469 Follow these rules and everything works fine.
1471 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Added new function silc_server_remove_clients_by_server to
1474 remove all client entries from ID list when the server connection
1475 is lost. In this case it is also important to invalidate all
1476 client entires as they hold the invalid server entry. This
1477 fixes fatal bug when server has lost connection and will reconnect
1480 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Made some sanity checks to silc_server_daemonise like to check
1483 whether the requested user and group actually exists.
1485 * Added sanity check to SKE's silc_ske_responder_finish to check
1486 that the public and private key actually is valid.
1488 * Invalidate the client's nickname when receiving Replace ID
1489 packet and the Client ID is being replaced. This means that the
1490 server will query the nickname if someone needs it (client)
1493 * Sort the ID Cache in client library when the ID Cache data
1494 has changed (needs sorting).
1496 * Do not allow for SILC client to create several connections to
1497 several servers. The client does not support windows right now
1498 and generating multiple connections causes weird behaviour.
1500 Irssi-silc client does support windows and can handle several
1501 connections without problems, see: www.irssi.org and SILC plugin.
1503 * Fixed some places where client was added to the IDList. The
1504 rule of thumb is following (in order to get everything right):
1505 If the client is directly connected local client then the
1506 `connection' argument must be set and `router' argument must be
1507 NULL to silc_idlist_add_client function. If the client is not
1508 directly connected client then the `router' argument must
1509 bet set and the `connection' argument must be NULL to the
1510 silc_idlist_add_client function.
1512 * The funtion silc_server_packet_send_local_channel actually did
1513 not check whether the client was locally connected or not. It
1514 does that now. Fixed a bug related to LEAVE command.
1516 * Fixed Remove Channel User payload parsing bug in server's
1517 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1519 * The server's silc_server_save_channel_key now checks also the
1520 global ID list for the channel as it might not be in the local
1521 list. Fixed a bug related to LEAVE command.
1523 * Is this the end of the [<unknown>] buglet that has been lurking
1524 around for a long time? A little for loop fix in server's
1525 silc_server_command_whois_parse that is used by both IDENTIFY
1526 and WHOIS command. At least, this was a clear bug and a cause
1527 of one type of [<unknown>] buglet.
1529 * WHOIS and IDENTIFY commands call the function
1530 silc_server_command_[whois/identify]_check function even if
1531 we are not router server.
1533 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Added --with-gmp configuration option. If set the GMP
1536 is always compiled in the SILC source tree. If not set then
1537 it is checked whether the system has the GMP3 installed. If
1538 it has then the GMP won't be compiled (the system's headers
1539 and library is used), if it doesn't have it then the GMP is
1540 compiled in the SILC source tree.
1542 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Changed RSA private exponent generation to what PKCS #1
1545 suggests. We try to find the smallest possible d by doing
1546 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1547 not security fix but optimization.
1549 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added new config entry [Identity] to fork the server and run
1552 it as specific user and group. A patch from Bostik.
1554 * Imported Dotconf configuration library into lib/dotconf.
1555 This will be used to create the SILC configuration files later.
1556 It will appear in the distsribution after this commit.
1558 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * A big code auditing weekend happening. Auditing code for
1561 obvious mistakes, bugs and errors. Also, removing any code
1564 Removed files for being obsolete:
1566 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1567 inline in the file lib/silcutil/silcbuffer.h)
1569 o lib/silcutil/silcbufutil.c (the header has inline versions)
1571 Changed code to fix possible error conditions:
1573 o The buffer formatting routines now check that the destination
1574 buffer really has enough space to add the data. This applies for
1575 both buffer formatting and unformatting
1576 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1577 unformatting was changed to accomodate following rules:
1578 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1579 sent to the function while XXX_*STRING will not allocate or copy
1580 the data into the buffer. Instead it sets the pointer from the
1581 buffer into the pointer sent as argument (XXX_*STRING used to
1582 require that the pointer must be allocated already). This change
1583 makes this whole thing a bit more consistent and more optimized
1584 (note that the data returned in the unformatting with XXX_*STRING
1585 must not be freed now). The routines return now -1 on error.
1587 o Tried to find all code that use buffer_format and buffer_unformat
1588 and added return value checking to prevent formatting and
1589 especially unformatting errors and possible subsequent fatal
1592 o Changed ske->x and ske->KEY to mallocated pointers in
1593 lib/silcske/silcske.h. Fixed possible data and memory leak.
1595 o Added return value checking to all *_parse* functions. Fixed
1596 many memory leaks as well.
1598 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1599 so that buffer overflows would not happen. All code now also
1600 checks the return value as it can fail.
1602 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Added reconnection support to server if the normal server looses
1605 its connection to the router (for example if router is rebooted).
1606 The server performs normal reconnection strategy implemented
1607 to the server. Affected file silcd/server.c.
1609 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1611 * Added new packet type SILC_PACKET_SET_MODE that is used to
1612 distribute the information about changed modes (for clients,
1613 channels and clients channel modes) to all routers in the
1614 network. Updated the protocol specification accordingly.
1616 Added functions into silcd/packet_send.c and
1617 silcd/packet_receive.c: silc_server_send_set_mode,
1618 silc_server_set_mode.
1620 Added new files silcmode.[ch] into lib/silccore that implements
1621 the encoding and decoding of Set Mode Payload. Added new type
1622 SilcSetModePayload. Moved the definitions of different modes
1623 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1625 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Oops, a little mistake in server's connection authentication
1628 protocol. The protocol is not ended with FAILURE but with
1629 SUCCESS if the authentication is Ok. :) Affected file is
1632 * Implemented NICK_CHANGE notify handling in server in the file
1633 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1634 the local clients on the channel. After the changing nickname
1635 in router environment snhould work and the [<unknown>] nickname
1636 should appear no more.
1638 The silc_server_replace_id function that receives the Replace ID
1639 payload now sends the NICK_CHANGE notify type also in the file
1640 silcd/packet_receive.c
1642 * Changed WHOIS and IDENTIFY command to support the maximum amount
1643 of arguments defined in protocol specs (3328 arguments). This
1644 fixed a bug that caused problems when there were more than three
1647 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Added extra parameter, command identifier, to the
1650 silc_client_send_command so that explicit command identifier
1653 Changed that ID list routines uses specific command identifier
1654 when sending WHOIS/IDENTIFY requests to the server so that they
1655 can be identified when the reply comes back.
1657 Affected files lib/silcclient/command.[ch],
1658 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1660 * Added `sender' argument to silc_server_packet_send_to_channel
1661 to indicaet the sender who originally sent the packet to us
1662 that we are now re-sending. Ignored if NULL. Affected file
1663 silcd/packet_send.[ch].
1665 * Added some server statistics support in silcd/server_internal.h
1666 SilcServerStatistics structure and around the server code. Also
1667 send some nice statistics information when client is connecting
1670 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Fixed channel ID decoding in server's JOIN command reply in
1673 silcd/command_reply.c
1675 * Fixed braodcasting of replace ID payload to not to send it if
1676 we are standalone server in silcd/packet_receive.c.
1678 * Fixed all channel message sending routines to not to send
1679 packets to clients that has router set, since they are routed
1680 separately in the same function earlier. Affects file
1681 silcd/packet_send.c and all channel packet sending functions.
1683 * In USERS reply, res_argv[i] are not allocated, the table
1684 is allocated. Thus changed that free the table, not its
1687 * In server's whois_check and identify_check if the client is
1688 locally connected do not send any WHOIS commands - they are not
1691 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Fixed some minor bugs in client when sending WHOIS command. The
1694 arguments was in wrong order.
1696 * Removed statis function add_to_channel from server in
1697 silcd/command.c that was previously used with the joining but
1700 * Tested USERS command in router environment successfully with two
1701 routers, two servers and two clients.
1703 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Reorganized the USERS command and command reply in client library
1706 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1707 When the command is given by user we register a pending command
1708 callback that will reprocess the command after the reply has been
1709 received from the server. When reprocessing the packet we then
1710 display the information. Thus, the USERS information is displayed
1711 now in the command callback instead of in the command reply
1712 callback. The processing of the command is same as previously
1713 when server has sent the command reply in the JOINing process.
1715 * Added to USERS command in silcd/command_reply.c to join the client,
1716 we didn't use to know about, to the channel after we've created
1717 a client entry for it. Also, for clienet we did know already still
1718 check whether it is on the channel or not and add it if not.
1720 * Removed silc_server_command_join_notify as the function and its
1723 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Changed the client's pending command handling to the same as the
1726 server's pending command handling. It is also now possible to
1727 execute command reply functions from other command reply
1728 function as the function callbacks for commands and command
1729 replies are one and same. The pending commands are not static
1730 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1731 in client connection context. Thus, pending commands are server
1732 connection specific as it is convenient.
1734 Changed the function silc_client_command_pending and
1735 silc_client_command_pending_del and added new function
1736 silc_client_command_pending_check. Removed the
1737 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1740 * Added cmd_ident, current command identifier, to the client
1741 connection context in lib/silcclient/client.h to keep track on
1742 command identifiers used in command sending. Client's command reply
1743 function handling now supports the mandatory command identifiers.
1745 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1746 funtions in client to fully support pending command callbacks.
1748 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1749 as one of the arguments to the application in the command reply
1752 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1753 before first releasing SILC but came back. Now it is removed again
1754 and should come back nomore. The FORWARDED flag was used only
1755 by the JOINing procedure by forwarding the command packet to router.
1756 Now, the JOINing procedure has been changed to more generic (due
1757 to various router environment issues) and FORWARDED is not needed
1758 anymore for anything. The protocol specification is yet to be
1761 Now, removed silc_server_packet_forward from server and the flag
1762 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1764 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Renamed NAMES command to USERS command. The NAMES was named that
1767 due to historical reasons. Now it is renamed. Also, rewrote
1768 parts of the USERS command. The nickname list is not sent anymore
1769 by the server. Only Client ID and mode lists are sent in the USERS
1770 command. Changed this also to the protocol specification.
1772 The client now resolves the names and stuff after it receives
1773 the USERS list from the server when joining to the channel.
1775 * WHOIS and IDENTIFY commands has been changed to support multiple
1776 Client ID's per command. One can now search for multiple users
1777 in the network by sending only one WHOIS or IDENTIFY command.
1778 Changed the code and the protocol specifications.
1780 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1781 uses silc_server_command_whois_parse to parse the request. */
1783 * If normal server, do not parse the WHOIS and IDENTIFY requests
1784 before sending it to the router. Saves some time.
1786 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Fixed JOIN command on client library. Wrong number of arguments
1789 used to crash the client.
1791 * Added silc_server_channel_has_global function to check whether
1792 channel has global users or not.
1794 * Added silc_server_channel_has_local function to check whether channel
1795 has locally connected clients on the channel.
1797 * The silc_server_remove_from_one_channel now checks whether the
1798 channel has global users or not after given client was removed from
1799 the channel. It also checks whether the channel has local clients
1800 on the channel anymore. If it does not have then the channel entry
1801 is removed as it is not needed anymore.
1803 * The silc_server_notify now checks on JOIN notify whether the joining
1804 client is one of locally connected or global. If it is global then
1805 the channel has now global users on the channel and that is marked
1806 to the channel entry. Also, it now saves the global client to
1807 global list who is joining and JOINs it to the channel. This is
1808 for normal server, that is.
1810 Changed silc_server_send_notify_on_channel,
1811 silc_server_packet_relay_to_channel and
1812 silc_server_packet_send_to_channel check if we are normal server
1813 and client has router set (ie. global client) do not send the
1814 message to that client, as it is already routed to our router.
1816 * Implemented LEAVE notify type handling in silc_server_notify
1819 * Tested LEAVE command in router environment successfully. Tested
1820 with two routers, two servers and two clients.
1824 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1826 * Implemented SIGNOFF notify type handling in silc_server_notify
1829 * silc_server_remove_id now removes the client entry from all channels
1830 it has joined and thusly sends SIGNOFF notify type.
1832 * Rewrote the NAMES list generation in server by removing two excess
1833 loops. The lists are created now inside one loop.
1835 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * silc_server_remove_channel_user checks now also global list
1838 for channel and client.
1840 * silc_server_new_channel_user checks now both local and global
1841 list for channel and client. Fixed a bug in client id decoding.
1842 Used to decode wrong buffer.
1844 * silc_server_channel_message checks now both local and global
1845 list for channel entry.
1847 * Tested channel joining (hence JOIN) in router environment
1848 successfully. Tested with two routers, two servers and two
1851 * Tested channel message sending in router environment successfully.
1853 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Added silc_server_save_channel_key into server.[ch] to save the
1856 received channel key in Channel Key payload processing. It is
1857 also used in JOIN command reply handling.
1859 Equivalent function silc_client_save_channel_key added into
1860 client.[ch] into client library.
1862 * Changed JOIN command reply to send information whether the channel
1863 was created or not (is existing already) and the channel key
1864 payload. Changed protocol specs accordingly.
1866 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1867 the request was sent by ID and not by nickname. Crashed on
1870 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1873 now correctly save the received data.
1875 * silc_server_free_sock_user_data now notifies routers in the
1876 network about entities leaving the network.
1878 At the same time implemented functions silc_server_remove_id
1879 and silc_server_send_remove_id to receive and send REMOVE_ID
1880 packets. The packet is used to notify routers in the network
1881 about leaving entities. The ID removed will become invalid in
1884 * Added function silc_idlist_del_server into server. Removes and
1885 free's server entry from ID list.
1887 * silc_server_private_message function now checks, if we are router,
1888 that the destination ID really is valid ID, naturally.
1890 * In router when NEW_ID packet is received (for new client) the
1891 hash of the Client ID is saved in the ID Cache but the
1892 client->nickname is set to NULL, instead of putting the hash
1895 IDENTIFY command now also checks that client->nickname must be
1896 valid. If it is not if will request the data from the server who
1897 owns the client. Added new function
1898 silc_server_command_identify_check.
1900 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1901 to set the command to already allocated Command Payload.
1903 * Tested private message sending in router environment with two
1904 routers, two servers and two clients. Fixed minor bugs and now
1907 * Fixed segfault from client's NAMES command. Used to crash if
1910 * Forwarded packets must not be routed even if it is not destined
1911 to the receiver. Changed server code comply with this.
1913 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Added `require_reverse_mapping' boolean value to ServerParams
1916 structure. If TRUE (not default) the server will require that
1917 the connecting host has fully qualified domain name.
1919 If the reverse mapping is not required and hostname could not be
1920 found the IP address is used as hostname.
1922 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Implemented version string checking to both client and server.
1925 The check is incomplete currently due to the abnormal version
1926 strings used in development version of SILC.
1928 * Changed all command functions in server to use the new
1931 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Changed char *data to unsigned char *data in ID Cache system to
1934 support binary data as ID Cache data. Changed code to support
1935 binary data in lib/silccore/idcache.c.
1937 * Renamed silc_server_packet_relay_command_reply to
1938 silc_server_command_reply as it is normal packet receiving
1939 function. Rewrote the function to accept command replys for
1940 servers and not only for clients.
1942 * Mark remote router always as registered server if we are connecting
1943 to it. Otherwise, commands sent by the router to us are ignored.
1945 * All ID List find routines now returns the ID Cache Entry pointer
1946 as well if requested.
1948 * WHOIS command works now in router environment, tested with two
1949 routers, two servers and two clients.
1951 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1952 in router environment (as it is almost equivalent to WHOIS) but
1953 hasn't been tested thoroughly. Added new functions:
1955 silc_server_command_identify_parse
1956 silc_server_command_identify_send_reply
1957 silc_server_command_identify_from_client
1958 silc_server_command_identify_from_server
1960 * Disabled route cache adding because adding two different ID's with
1961 same IP replaces the old cache entry thus giving wrong route.
1962 The entry->router->connection is always the fastest route anyway
1963 so route cache may not be needed. Of course, new routes maybe
1964 established after receiving the ID when the entry->router->connection
1965 might not be anymore the most optimal.
1967 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Add route cache for received ID for fast routing.
1971 * Added silc_server_packet_route to route received packet on router
1972 that is not destined to us.
1974 * Renamed silc_server_get_route to silc_server_route_get.
1976 * Added id_string and id_string_len fields into SilcServer to
1977 include encoded ServerID for fast comparing without excess
1978 encoding of the ID's.
1980 * Cleaned up WHOIS command on server side. Added following static
1983 silc_server_command_whois_parse
1984 silc_server_command_whois_check
1985 silc_server_command_whois_send_reply
1986 silc_server_command_whois_from_client
1987 silc_server_command_whois_from_server
1989 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1990 arguments in command replies. All command functions should be
1991 updated to use this macro.
1993 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Minor typo fixes on command reply handling on server.
1997 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Added silc_server_command_add_to_channel internal routine to add
2000 the client to the channel after router has created the channel and
2001 sent command reply to the server.
2003 * Added generic silc_server_send_command to send any command from
2006 * Use static buffer with ID rendering instead of duplicating data.
2008 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Fixed a channel user mode bug when joining to a channel server gave
2011 everybody channel founder rights, oops.
2013 * We mark ourselves as the router of the incoming server connection
2014 if we are router ourselves. This way we can check in some packet
2015 sending functions whether it is locally connected server. For
2016 incoming router connections we put NULL.
2018 * For router sending packets locally means now always sending the
2019 packet cell wide; to local clients and local servers. For normal
2020 server sending packet locally means sending it to only local
2023 * Fixed the JOIN command to really work in router environment. If the
2024 channel is created it is always created by the router. Router is
2025 also responsible of making the initial joining to the channel,
2026 sending JOIN notify to the sending server and distributing
2027 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2028 does not exist server doesn't do anything else but forward the
2029 command to the router which performs everything.
2031 * Added silc_server_send_channel_key function to send the Channel Key
2034 * Added silc_server_create_channel_key to create new channel key. The
2035 channel key is now re-generated everytime someone joins or leaves
2036 a channel, as protocol dictates. Note: channel->key_len is the
2039 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2042 packet_receive.[ch] to separate packet sending and receiving
2043 routines. The server.[ch] now includes everything else including
2044 actual packet processing (writing and reading data) and other
2047 Renamed silc_server_private_message_send_internal to
2048 silc_server_send_private_message. The routine is still though
2049 used only to relay private messages as server does not send
2050 private messages itself.
2052 Renamed silc_server_new_channel to silc_server_create_new_channel
2053 and added new function sicl_server_new_channel that handles the
2054 incoming New Channel packet. Added also new sending function
2055 silc_server_send_new_channel to send New Channel Payload.
2057 * Added new function silc_server_notify to process incoming notify
2058 packet to the server/router. Server may then relay the notify
2059 to clients if needed.
2061 * Added new function silc_server_new_channel_user to process incoming
2062 New Channel User packet. Router will redistribute the packet and
2063 send JOIN notify to its local clients and locally connected servers
2064 if needed. Normal server will send JOIN notify to its local client
2065 on same channel when received this packet. Added also corresponding
2066 sending function silc_server_send_new_channel_user to sent the
2069 * Added boolean route argument to send_notif_to_channel and
2070 packet_send_to_channel functions to attempt to route the packet
2071 if it is TRUE and send only locally if it is FALSE.
2073 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * silc_server_replace_id now broadcasts the received replace ID
2076 packet if it is not broadcast packet already. The router must
2077 broadcast to inform other routers about changed ID.
2079 * Added backpointer to server's router into SilcServer context in
2080 silcd/server_internal.h.
2082 * Fixed silc_server_packet_broadcast to send correct broadcast
2085 * The channel key is now distributed to the local client as soon
2086 as it is received from the router (in router environment) so that
2087 no other packet may be sent for the channel until client has
2090 * silc_server_remove_channel_user now broadcasts the received
2091 Remove Channel User packet if it is not broadcast packet already.
2092 The router must broadcast to inform other routers about removed
2095 * Added users field into SilcPacketContext that is a reference count
2096 of the context. One can increase the reference count by calling
2097 silc_packet_context_dup which is now changed to just increase the
2098 reference count instead of duplicating the data. The reference
2099 count is decresed by calling silc_packet_context_free that will
2100 free the data after the reference count hits zero.
2102 For now on the packet context and everything allocated into it
2103 (including the raw packet from network) must be freed by calling
2104 the new silc_packet_context_free function. Added also new function
2105 silc_packet_context_alloc that must be used now to allocate the
2106 context. This also means that if a routine is asynchronous from
2107 silc_[client/server]_packet_parse_type the packet context must
2108 be duplicated by calling silc_packet_context_dup. Otherwise it
2109 gets free'd after silc_[client/server]_packet_parse_type returns.
2110 Also, one must remember that if packet is duplicated then its
2111 reference count must be decresed by calling the free function as
2112 many times as it was duplicated.
2114 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2115 from both client and server.
2117 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Made joining to a channel working in router environment.
2121 * Cleaned up JOIN command on server side and create function
2122 silc_server_command_join_channel internal routine to make the
2125 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Changed silc_command_pending list to SilcDList. Also, added
2128 `ident' field to SilcServerCommandPending structure to identify
2129 the reply and to call correct callback.
2131 Added silc_server_command_pending_check function to replace the
2132 corresnponding macro. The silc_command_pending list is not
2135 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2136 to set identifier to previously allocated Command Payload. It
2137 is used to set identifier for command when resending Command
2140 * Added silc_command_payload_encode_payload to encode Command
2141 Payload buffer from SilcCommandPayload structure.
2143 * Added silc_argument_payload_encode_payload to encode Argument
2144 payload buffer from SilcArgumentPayload structure.
2146 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Changed WHOIS command to support router connection on server side.
2149 The whois request is always sent to router unless the server is
2150 standalone server. After server has received the reply from the
2151 router will it send the reply to the client.
2153 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2154 broadcast received broadcast packet. The function is used only
2155 by router. The broadcast packet is always sent to the router's
2158 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2159 render given ID to printable string, for log files for example.
2161 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Made basic router to router connections working. At least they
2164 can now connect to each other but nothing really works the way
2165 they are supposed - yet.
2167 * Added new initiator token to RouterConnection configuration
2168 file in silcd/serverconfig.[ch]. It is used to tell whether we
2169 are the initiator to the remote router or whether we'll expect
2170 the other end to connect.
2172 * Moved registering of listener task to silc_server_init, hence
2173 the server starts listenning as soon as it is run, even if it
2174 does not have connections to other routers. Let's see how well
2177 * Changed default connection retry timeouts for more suitable in
2180 * Removed cipher and such arguments from silc_idlist_add_client
2181 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2182 Added new function silc_idlist_add_data to add the keys and stuff
2185 * Added SilcIDListData structure and added it to SilcClientEntry
2186 and SilcServerEntry as their first field in the structure. This
2187 way we can explicitly cast the ID entries to the SilcIDListData
2188 structure and get common data for the entries. In past, we had
2189 to first check what type of connection it is and then cast it to
2190 correct ID entry type. Now, we can directly cast the opaque
2191 pointer to the SilcIDListData (no matter what ID entry it actually
2192 is) and get the data needed.
2194 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2197 in some circumstances even if threre were timeout tasks, though not
2198 IO tasks, but tasks anyway. Now fixed.
2200 * Defined SilcServerConnection structure to hold connection specific
2201 stuff about directly connected servers and routers. The definition
2202 is currently in silcd/server_internal.h. I thought about having
2203 a bit more important role fro this struct but for now it is used
2204 only when connecting to other server (or router actually).
2206 * Added connecting retry support in server when connecting to
2207 router(s). The retry feature implement exponential backoff
2208 algorithm. Also, added SilcServerParams structure to hold default
2209 parameters for server. For now, it include these retry settings
2210 and are hard coded. After server is moded to be as Silc Server
2211 Library this structure will be more important.
2213 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Changed client librarys channel->clients table to SilcList and
2216 changed code accordingly.
2218 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Changed client's channel table to SilcList and changed code
2221 accordingly. Also changed SilcChannelClientEntry to include back-
2222 pointer to the channel so that client entry can use that structure
2223 as list as well and we have fast cross-reference to the channel.
2224 This change dramatically decreased the complexity of channel
2225 handling with client entry and vice versa (removed one extra
2226 loop when searching for channel entry from many functions).
2228 * Changed server->sim from table to SilcDList and changed code
2231 * NAMES command can now be used from user interface. It will show
2232 the user list on the channel, neatly.
2234 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2235 Code now saves realname of the user if it becomes available.
2237 * Renamed configure.in to configure.in.pre and made ./prepare
2238 script to automatically add correct version string to
2239 configure.in which it creates from configure.in.pre.
2241 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * NAMES command reply now shows users mode with the nickname when
2246 * Moved silc_client_ch[u]mode[_char] functions from
2247 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2248 place sucks, they are utility functions and should be in some
2251 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2253 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2256 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Added TRQ (efficient deque and list library) into lib/trq. This is
2261 a very good list library that is currently used in the SILC. Defined
2262 SilcList API over the library because I didn't like the API very
2263 much. See lib/trq/silclist.h for the API and examples of how to
2264 use the API. Fixed various places in the code to use the new
2265 SilcList API. The SilcList is meant for lists that has a structure
2266 already defined as a list. It is not suitable to add just some
2267 context to the list (in TRQ, the context is the list actually).
2269 So, I defined SilcDList that can be used for the purpose where
2270 predefined list structure does not exit. This can be used as
2271 such list. Now some context just can be added to the SilcDList.
2272 Currently this list is not used in the SILC just yet, though there
2273 are a lot places where this can replace dynamically allocated
2274 tables and I will fix these places, later, to use SilcDList.
2275 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2276 and use TRQ internally).
2278 Also fixed some annoying warning messages that the original TRQ
2279 code generated. Also minor changes to TRQ's Makefile.in.
2281 * Added support for querying by Client ID to both WHOIS and
2282 IDENTIFY commands into server, as required by the protocol.
2284 * Removed method function pointers from SilcBuffer structure. They
2285 weren't used to anything and just increased the context size for
2286 no good reason. This change also made silc_buffer_alloc and
2287 silc_buffer_free functions inline functions.
2289 * Disabled command flooding detection support until it's fixed so
2290 that it accepts commands in but does not execute them more than once
2293 * Added silc_net_localhost(), to return local hostname, into
2294 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2295 that must be initialized before calling silc_client_init.
2297 * Added new function: silc_server_send_notify_on_channels to send
2298 notify messages to all channels client has joined. It is assured
2299 that the message is sent only once per client.
2301 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2302 lib/silcutil/silcutil.[ch] as silc_format function. The new
2303 function is generic and is used by server as well, not only by
2304 the logging routines.
2306 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2307 the provided version string was not acceptable. Added new function:
2308 silc_ske_check_version into lib/silcske/silcske.h. The function
2309 must be implemented by the application (client or server) and it
2310 does not reside in the SKE library. The function checks the version
2311 string remote end sent.
2313 * Added back pointers (to opaque context and to SilcSocketConnection)
2314 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2316 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2317 duplicate packet context structure.
2319 * Changed `notify' client operation to send same arguments as client
2320 receives from server except for ID's. ID's are mapped to correct
2321 ID entry and that is returned. Also, if channel entry is not sent
2322 by server but the notify is for channel the channel entry is sent
2323 to application (otherwise application doesn't know that it is for
2324 channel (library gets it from packet's Destination ID)).
2326 * Added silc_client_remove_from_channels into client library to
2327 remove a client from all channels it has joined to. Used when
2328 received SIGNOFF notify from server. Added also new function
2329 silc_client_replace_from_channels to replace old ID entry with
2330 new ID entry on all channels. Used when received NICK_CHANGE
2333 * Fixed ID Cache list handling in silc_idlist_get_client in
2334 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2335 to get (or query) client by ID.
2337 * Updated TODO list.
2339 * Added connection authentication status message defined by the
2340 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2341 support for these into the code in client and server side.
2343 * Added generic function silc_client_send_command to send any command
2344 with variable argument list. Application should use this function
2345 to send commands if the command functions provided by the library
2346 does not suite for the application's user interface needs.
2348 * Added new `failure' client operation. Application is notified about
2349 received failure packet if client is executing a protocol. In this
2350 case the protocol's execution has failed.
2352 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2353 is required by the protocol.
2355 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2356 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2359 * Added status flag to SilcSKE object to indicate realtime status
2360 of the SKE protocol.
2362 * Application receives now exactly same command reply arguments as
2363 the library receives from server. However, if ID is received the
2364 corresponding ID entry is returned to the application (eg. Client
2365 ID is mapped to correct SilcClientEntry entry and that is returned).
2366 Changed command_reply client operation due to this change.
2368 * Changed all ID's in commands and in command replys as ID Payloads.
2369 Change affected both client and server side codes.
2371 All ID's sent in SILC network (with execption of ID's in SILC
2372 Packet header) are sent in ID Payload to support variable length
2375 * Server now notifies nick changes and notifies all clients on
2376 the channels about the new nickname (about the new Client ID,
2379 * Implemented CMODE command to change channel modes. Supports all
2380 channel modes defined by the protocol specs except ban and invite
2381 lists. (Also, private channel key mode is supported but support for
2382 setting private channel key in client is missing, thus, this mode
2383 has no effect on client side (except that server requires that the
2384 client uses private channel key and normal channel traffic does not
2387 Also, invite mode works per se, but INVITE command does not work
2388 yet correctly, so you can set channel as invite only channel but
2389 inviting clients to the channel does not work (it is yet to be
2390 thought what's the best way to do it).
2392 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2393 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2394 Implemented CUMODE command to change user's mode on the channel.
2395 Supports all modes defined by the protocol specs.
2397 * Added NAMES command reply to return users modes on the channel.
2399 * Removed unnecessary and slow ciphers from lib/silccrypt.
2401 * Set SO_KEEPALIVE option to connection sockets by default.
2403 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2405 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2406 redefined the Notify Payload into protocol specs.
2408 * Added silc_id_payload_parse_id to get ID directly from raw
2411 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2414 accept searching by Client ID as well.
2416 * Added support for LEAVE and SIGNOFF notify types in client library.
2418 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2419 to parse ID Payload from raw data.
2421 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Added flags parameter into silc_ske_assemble_security_properties
2424 function in lib/silcske/silcske.[ch].
2426 * Changed notify client operation to fit better for notify messages
2427 sent by server. The notify payload received from server is now
2428 passed to the application (after parsing it to SilcNotifyPayload).
2429 It is application's responsibility to retrieve the arguments
2430 from the payload and show the message the way it wants. The message
2431 sent by server is implementation specific.
2433 * Changed public keys to comply with the protocol specification.
2434 Old public keys are not supported anymore and are not compatible.
2436 * Removed nickname from Channel Payload as the latest draft removed
2437 it. The client must resolve the nickname from the NAMES command
2438 reply received when it joined the channel.
2440 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2442 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Fixed some errors in protocol specification drafts.
2446 * Created lib/silccore/silcnotify.c to implement Notify Payload
2447 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2448 generic payloads described by protocol specifications. The file
2449 includes implementations for ID Payload and Argument Payload.
2451 * Changed Command Payload implementation to use the new Argument
2452 Payload. Changed command_xxxx_payload to command_payload_xxxx
2453 to comply with SILC coding conventions.
2455 * Added suppport for Argument Payload handling in Notify Payload
2456 implementation as protocol requires it. Added the new support
2457 into server and client lib as well.
2459 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Added support for multiple nicknames on same channel. [n] is
2462 added locally to the nickname if there are more than one same
2463 nicknames on the channel.
2465 * Server now sends all nicknames that matched WHOIS request.
2466 Client also shows the list received from server.
2468 * Added TOPIC command to client side. User can now set and show
2469 current topic on channel.
2471 * Added MOTD command to client and server. Also, server sends the
2472 motd when client connects to the server.
2474 * Changed version strings to comply ISO 8601.
2476 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Fixed protocol error handling in client library. It should now
2479 cope even if the SKE fails for some reason.
2481 * Made new protocol specification drafts for submitting to IETF.
2483 * Implemented TOPIC command to server in silcd/command.c.
2485 * Added two new notify types into lib/silccore/silcnotify.h:
2486 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2487 notify nickname change and topic setting/change on a channel.
2489 * API change of command_reply operation in client library. The
2490 application gets now the status type received from server as well.
2492 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2496 * Cras fixed and optimized the packet handling even further and
2497 it should work now. Minor change to the prototype of function
2498 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2500 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Added new function into lib/silcutil/silcschedule.[ch]:
2503 silc_schedule_with_fd to select() a specified fd. The function
2504 returns after timeout expires or data arrives or goes. The
2505 function is used by packet routines to wait that all data is
2506 received from network.
2508 * Fixed data reading from network in lib/silccore/silcpacket.c.
2509 The code now assures that all data is read from the fd and then
2510 continues packet processing. This was a bug fix since the code
2511 used to drop some data in some circumstances.
2513 * Added new function into lib/silcclient/client.[ch]:
2514 silc_client_start_key_exchange to start key exchange after
2515 connection has been established to server. The code internally
2516 now uses this funtion but its main purpose was to provide it
2517 for applications that perform their own connecting. After
2518 application has created a connection it merely calls this
2519 function to start the key exchange between client and server.
2520 The library takes care of everything else after that.
2522 Updated also lib/silcclient/README to explain the usage of
2525 * Do not send to application information that connection has
2526 been established. Application gets notified it by connect
2529 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Applied cras's patch to add silc_schedule_one function. The
2532 function runs scheduler once and returns.
2534 * Fixed the scheduler after cras messed it up. The timeout
2535 handling works now as it's supposed to work.
2537 * Added into lib/silccore/ silcnotify.h to include notify
2538 message types support. Changed silc_server_send_notify*
2539 functions, in server.[ch], to support those new notify types.
2540 Added the support for the notify types into client library,
2541 as well. Added new notify client operation into ops.h in
2544 * Changed silc_server_packet_send_to_channel to send normal
2545 packets instead of just channel message packets. The function
2546 is now used to send the notify packets to channels. It is not
2547 used to send channel message packets anymore, as server never
2550 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2551 va_arg()s as it seems to require it nowadays. I guess, if SILC
2552 is compiled with older va_arg() the new code should work anyway.
2554 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Splitted core library. Core library (lib/silccore) includes
2557 now only SILC protocol specific core (and common) components.
2558 Created new utility library (lib/silcutil) that includes more
2559 generic purpose stuff. The stuff for util library was taken
2560 from the old core library. This was minor and easy split.
2562 * Created SILC Client Library (lib/silcclient) that includes
2563 implementation of the SILC client without user interface. This
2564 was major move from silc/ directory. The code has been changed
2565 so that it is transparent towards the user interface. The
2566 silc/ directory includes now the same user interface as before
2567 and it uses the new client library. Read lib/silcclient/README.
2568 Basicly, the client library performs everything else related
2569 to SILC except user interface handling. Also, configuration
2570 files are considered to be part of user interface and library
2571 does not handle them.
2573 This change also changed a lot of structures, function naming etc.
2574 Most important change was that SilcClientWindow object was
2575 renamed to SilcClientConnection in the client library. Created
2576 also new file lib/silcclient/ops.h. Also added new files
2577 silc/local_command.[ch] and silc/client_ops.[ch].
2579 All these changes were made to make it easier for user interface
2580 designers to create what ever user interface for the SILC client
2583 It is also expected that the server will be moved to lib
2584 directory as well and SILC Server Library will be created;
2585 sometimes in the future.
2587 * Removed Local commands from lib/silccore/silccommand.h as
2588 they are application specific and new client library does not
2589 handle any of those anymore.
2591 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2592 old client implementation in silc/.
2594 * Added support for callback functions in SILC_LOG_* macros.
2595 Application can now set its own callbacks that will be called
2596 instead of using the default functions that will always print
2597 the debug messages to stderr (or stdout). Also, debugging can
2598 now be disabled by setting silc_debug to FALSE and re-enabled by
2599 setting it to TRUE. Note, that logging will still work even
2600 if debugging is disabled.
2602 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2603 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2604 silc_log_reset_debug_callbacks.
2606 * To enable debugging in silc client one must give now -d
2607 option on command line.
2609 * Changed silc_schedule_init to automatically allocate task queues
2610 if they are not allocated before calling it.
2612 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Added GMP 3.1 into math library.
2616 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2619 a channel in SILC network. The packet is used by servers and
2620 routers to notify other routers that user has left a channel.
2621 This little feature was missing until now. Added the feature
2622 to protocol specification as well.
2624 Added functions: silc_server_send_remove_channel_user and
2625 silc_server_remove_channel_user into server.[ch].
2627 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2628 lib/silccore/silcpacket.h. However, they are not implemented
2631 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Fixed joining to a channel and sending channel messages
2634 between server and router. The channel message sending should
2635 now work inside a cell.
2637 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Fixed the private message sending between server and router.
2640 The private message sending should now work inside a cell.
2642 * Added silc_server_replace_id into server.[ch] to replace
2643 existing ID in the SILC network.
2645 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2646 and silc_idlist_replace_server_id into idlist.[ch] in server.
2648 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Fixed the server to server connections. Server can again now
2651 connect to router. Router to router connections probably does
2654 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Added dynamic protocol registering support. Now protocols can
2657 registered and unregistered on the fly. Patch by cras.
2659 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added lib/contrib directory to hold routines that some platforms
2662 don't have but are needed by SILC.
2664 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2665 into lin/contrib to provide getopt() and getopt_long() for
2666 those who don't have it.
2668 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2670 * Added AWAY command to client. When away message is set and
2671 client receives a private message packet the client automatically
2672 replies to the sender with the away message.
2674 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2675 bug seemed to be the cause of recent problems when compiling
2678 * Added version detection support to SKE protocol specification
2679 and added the new changes to the SKE implementation as well.
2680 There were other minor changes in the SKE protocol as well.
2682 Many changes in lib/silcske/silcske.[ch] and in
2683 lib/silcske/payload.[ch].
2685 * Added ^U functionality, clear input line. Patch from cras.
2687 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Mainly small bugfixes on core library. Fixed some debugging
2690 logging and buffer overflow in silclog.c.
2692 * Updated config.sub and config.guess on the distribution tree.
2694 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Added command lagging support in server. Client may execute
2697 commands now only once in two seconds.
2699 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Optimized packet reception. MAC computation and checking is now
2702 also more optimized. A lot previously duplicated code is now
2703 used as generic by both client and server.
2705 * Fixed key pair generation in clientutil.c
2707 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Added into lib/silccore/silcbufutil.[ch] new function;
2710 silc_buffer_realloc.
2712 * Moved generic packet sending/encryption functions to
2713 lib/silccore/silcpacket.[ch] from client and server. Some
2714 rewriting of the functions.
2716 * Moved all generic packet reception/decryption functions to
2717 lib/silccore/silcpacket.[ch] from client and server. The
2718 packet processing is now much cleaner in both client and server.
2719 These were major changes in both client and server.
2721 * Created many common functions in server to do packet sending.
2722 Previously code were duplicated a lot, this has been removed
2725 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Rewrote major parts of the ID cache system. Don't know
2728 whether it is better now or not but at least the API is more
2731 * Major rewrite on ID cache stuff on client because of the ID
2732 cache API changes. Added idlist.c to client.
2734 * Also major rewrite on ID cache stuff on server as well.
2735 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2736 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2737 in hand, instead they are all put into the ID cache system now.
2738 All server_idlist_* routines uses ID cache now instead of
2739 traversing its own lists (those lists does not exist anymore).
2740 SilcIDList though still exists. Also, SilcXXXEntry's are
2743 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Finally made the SKE implementation compliant to the protocol
2746 specification. All mp integers are now binary encoded as
2747 opposed being HEX encoded.
2749 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2752 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2753 functions: silc_[encode/decode]_pem. Also added function
2754 silc_encode_pem_file to PEM encode with newlines ('\n') for
2757 * SILC public keys are now encoded either PEM or binary. Same
2758 option is for private keys as well. By default private keys
2759 are binary encoded and public keys PEM encoded. Silly HEX
2760 encoding were removed.
2762 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2763 function to create fingerprints.
2765 * Fixed a bug in SHA1; does not change the original data anymore.
2767 * Partly implemented INFO command on client and server side.
2768 Fixed CLEAR command. Changes to SERVER command; show current
2769 server(s) when giving command without arguments. Added
2770 VERSION command to client.
2772 * Added check to server that unregistered connections cannot
2773 execute commands (unless it is specificly allowed).
2775 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Fixed screen refresh.
2779 * Fixed channel joining bug from client. On some circumstances
2780 client tried to join to a channel it had already joined.
2782 * Added public key verification process into client's protocol.c.
2783 The client now verifies the public key from user and saves
2784 it into ~./silc/serverkeys/ directory.
2786 Added into: clientutil.[ch]: silc_client_verify_server_key.
2788 * Changed SKE protocol's silc_ske_initiator_finish function
2789 to accept callback function that verifies the received public
2790 key. Removed old silc_ske_verify_public_key function.
2792 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2795 silc_pkcs_private_key[_data]_set.
2797 * Made the password and public authentication more cleaner in
2798 server's protocol.c.
2800 * Removed historic and obsolete protocol `channel_auth' from
2801 both client and server.
2803 * Removed wrong way of sending command status messages from
2804 server to client in server's command.c. The old way violated
2805 protocol specification.
2807 Changes to silccore/silccommand.[ch]: removed
2808 silc_command_encode_status_payload -> not needed anymore,
2809 changed silc_command_encode_payload_va to accept extra
2810 argument on variable argument list. The argument type must
2811 now be provided to the function. Also, added new function:
2812 silc_command_encode_reply_payload_va which is same as
2813 normal command_encode_payload_va except command status type
2814 is provided as extra argument.
2816 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Added ~./silc directory handling. The directory includes the
2819 public and private keys for the client.
2821 Added silc_client_check_silc_dir, silc_client_create_identifier
2822 and silc_client_load_keys.
2824 * Implemented SILC protocol compliant public key. Added public
2825 and private key saving to and loading from files.
2827 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2828 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2829 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2830 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

2838 * Added silc_server_get_route (route.[ch]) to get connection
2839 data for the fastest route for given ID.
2841 * Implemented INVITE command on client and server. The command
2842 were re-defined in the SILC Protocol Specification and the
2843 implementation now complies with the specification.
2845 * Implemented PING command on client and server.
2847 * Implemented NAMES command on client and server. The server side

2861 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
