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

169 notify between routers.
171 * Implemented the INVITE command correctly to the server.
173 * Implemented the INVITE notify type handling in the server.
175 * Implemented the INVITE command to the client library and on the
178 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Added function silc_server_get_client_resolve to find the
181 client entry by ID from all ID lists and then resolve it
182 (using WHOIS) if it cannot be found. Affected file is
185 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Implemented the BAN command to the client library.
189 * The JOIN command in the server now checks the invite list
192 * Changed the silc_command_reply_payload_encode_va and the
193 silc_command_payload_encode_va to support that if argument is
194 NULL it ignores and checks the next argument. Affected file
195 lib/silccore/silccommand.c.
197 * Added silc_server_send_notify_ban to send the BAN notify
198 type between routers.
200 * Chaned the silc_notify_payload_encode to support that if
201 argument is NULL it ignores and checks the next argument.
202 Affected file lib/silccore/silcnotify.c.
204 * Tested ban lists in router environment successfully.
206 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Implemented BAN command to the server, in silcd/command.[ch].
210 * Removed the BAN and INVITE_LIST modes from the CMODE command
213 * Added function silc_string_match to regex match two strings.
214 Affected files lib/silcutil/silcutil.[ch].
216 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Redefined parts of the SilcChannelEntry in the server to support
219 the new ban and invite lists.
221 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Redefined the INVITE command. The same command can be used to
224 invite individuals to the channel but also to manage the invite
225 list of the channel (to add to and remove from the invite list).
226 Updated the protocol specs.
228 * Added new command SILC_COMMAND_BAN that can be used to manage
229 the ban list of the channel. Updated the protocol specs.
231 * Removed the channel modes: the SILC_CMODE_BAN and the
232 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
233 in the CMODE command. The equivalent features are now available
234 using INVITE and BAN commands. Updated the protocol specs.
236 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
237 in the network about change in the current ban list. The notify
238 type is not used by the client.
240 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
241 support the invite lists.
243 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Added new function silc_string_regexify that converts string
246 including wildcard characters into regex string that can
247 be used by the GNU regex library. Added into the file
248 lib/silcutil/silcutil.[ch].
250 Added silc_string_regex_combine to combine to regex strings
251 into one so that they can be used as one regex string by
252 the GNU regex library. Added into the file
253 lib/silcutil/silcutil.[ch].
255 Added silc_string_regex_match to match two strings. It returns
256 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
258 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Imported GNU regex to the soruce tree into lib/contrib.
261 Fixed some compiler warning from the regex.c.
263 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Fixed MOTD command in the server to work in router environment.
267 * Fixed the MOTD command in the client library to support
268 the server argument in the command.
270 * Added `nickname_len' argument to the silc_idlist_add_client
271 in the server, as the `nickname' argument may be binary data
274 * Added silc_idlist_get_channels to return all channels from
277 * Implemented LIST command to the server. Affected file is
280 * Implemented the LIST command to the client library and on the
283 * Added [<user count>] argument to the LIST command reply.
284 With private channels the user count is not shown.
286 * Updated TODO and README.
288 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * The client entry's data.registered must be TRUE even with
291 global client entry on global client list. The data.registered
292 is used to check whether the client is anymore in the network,
293 for example with WHOWAS command so it must be valid.
295 * Fixed the WHOWAS command in the server. It now actually works
296 in router environment. Added function into silcd/command_reply.c
297 silc_server_command_reply_whowas_save.
299 * Added silc_idlist_purge function to the silcd/idlist.c
300 to periodically purge the ID Cache.
302 * Fixed INFO command in the server. It works now in router
303 environment. Added <server name> argument to the INFO command
304 reply. Updated the protocol specs.
306 * Fixed minor bug in silc_idcache_purge to not purge if the
307 expire value is zero.
309 * Fixed various bugs in WHOIS and IDENTIFY command handling as
310 they were buggy because of the WHOWAS information.
312 * Fixed local command MSG to handle the async resolving of
313 the remote client properly. It used to fail the first MSG.
314 Affected file silc/local_command.c.
316 * Added `data_len' field to SilcIDCache context.
318 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Update TODO. Todo in commands in the server.
322 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
325 used by routers as broadcast packet to inform other routers
326 about the changed user mode.
328 Implemented the notify handling in the server. Affected file is
329 silcd/packet_receive.c. Added the function
330 silc_server_send_notify_umode to the silcd/packet_send.[ch].
332 * Added new generic Channel Payload and deprecated the New Channel
333 Payload. The New Channel Payload is now the generic Channel
336 * Added new argument `mode' to the silc_server_send_new_channel
337 as it is required in the Channel Payload now.
339 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
340 and created a new and real SilChannelPayload to represent the
341 new generic Channel Payload. Implemented the encode/decode
342 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
344 * Added silc_server_get_client_channel_list to return the list
345 of channels the client has joined for WHOIS command reply.
346 Affected file silcd/server.[ch].
348 * Implemented the channel list sending in the WHOIS command reply
349 in server and in the client.
351 Implemented the channel list displaying on the user interface
352 as well. Affected file silc/client_ops.c.
354 * Added silc_channel_payload_parse_list to parse list of Channel
355 Payloads. It returns SilcDList list of SilcChannelPayloads.
356 Client for example can use this function to parse the list of
357 channels it receives in the WHOIS command reply. The caller
358 must free the list by calling silc_channel_payload_list_free.
359 Affected files lib/silccore/silcchannel.[ch].
361 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added one new argument <user mode> to the WHOIS command reply
364 to return the mode of the user in SILC. Updated the protocol
367 Implemented it to the server and client.
369 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Fixed the mode printing on the user interface on joining.
372 Affected file silc/client_ops.c.
374 * Implemented the UMODE command and user modes in general to the
375 client library and to the user interface.
377 * Implemented the UMODE command to the server.
379 * The server now sends UNKNOWN_COMMAND error status if client sends
380 unknown command. Affected file silcd/command.c.
382 * All server commands now handle the command identifier the right
383 way when sending the command reply to the client. The client can
384 use to identify the command replies with the identifier.
386 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Added silc_server_get_client_route to resolve the route to
389 the client indicated by the client ID. Affected file is
392 * Added silc_server_relay_packet as general function to relay
393 packet to arbitrary destination. This deprecates functions
394 like _send_private_message_key, _relay_notify etc. Affected
395 file is silcd/packet_send.[ch].
397 Removed silc_server_send_key_agreement,
398 silc_server_send_private_message_key and
399 silc_server_packet_relay_notify functions from the file
400 silcd/packet_send.[ch].
404 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
405 server. Affected file silcd/packet_receive.[ch].
407 * Implemented the KILL command to the client. Implemented the
408 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
409 Affected files lib/silcclient/command[_reply].c and
410 lib/silcclient/client_notify.c. Implemented the KILL notify
411 printing in the user inteface.
413 * Fixed a lot silc_parse_nick memory leaks from the client
414 library in the file lib/silcclient/command.c.
416 * Changed the silc_server_send_notify_on_channels's `sender'
417 argument from SilcSocketConnection to SilcClientEntry to
418 check the sender as entry and not as connection object and not
419 to send to the client provided as argument. The affected file
420 is silcd/packet_send.[ch].
422 * The notify packets that are destined directly to the client used
423 to not to be processed by the server. Now changed that and the
424 server processes all notify packets. After relaying the packet
425 to the client the notify packet is processed in the server.
427 * The silc_server_free_client_data now checks whether there is
428 pending outgoing traffic for the client and purges the data to
429 the network before removing the client entry.
431 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
434 an client is killed from the SILC Network. Updated the protocol
437 Added new function silc_server_send_notify_killed to the
438 silcd/packet_send.[ch].
440 * Added function silc_server_packet_relay_notify to relay notify
441 packets that are destined directly to a client. In this case
442 the server does not process the notify packets but merely relays
443 it to the client. Affected file silcd/packet_send.[ch].
445 Added also silc_server_packet_process_relay_notify to check
446 whereto relay the notify. Affected file is
447 silcd/packet_receive.[ch].
449 * Implemented the KILL command to the server.
453 * Added the backup schema desgined last fall to the protocol
454 specs for everyone to see. The specification is in the
455 *-spec-xx.txt draft and the packet type definitions for the
456 backup routers is in *-pp-xx.txt draft. Thusly, added also
457 new packet type SILC_PACKET_CELL_ROUTERS.
459 * A big security problem in the implementation discovered. The
460 signoff of an client did not cause new channel key generation
461 which it of course should've done. The channel keys must be
462 always re-generated when client leaves (or signoffs) the channel.
463 The silc_server_remove_from_channels funtion now handles
464 the channel key re-generation.
466 * Added `sender' argument to the silc_server_send_notify_on_channels
467 to not to send the client provided as argument. Affected file
468 silcd/packet_send.[ch].
470 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Implemented OPER and SILCOPER commands into the server and
475 * Added silc_auth_verify and silc_auth_verify_data to verify
476 the authentication directly from the authentication payload.
477 It supports verifying both passphrase and public key based
478 authentication. Affected file lib/silccore/silcauth.[ch].
480 * Added `hash' field to the SilcIDListData structure. It is the
481 hash negotiated in the SKE protocol. Affected file is
484 * Slight redesigning of the SilcAuthPayload handling routines.
485 Do not send SilcPKCS but SilcPublicKey as argument.
487 * Implemented the public key authentication support to the
488 serverconfig. The public key is loaded from the provided path
489 and saved as authentication data to void * pointer. Thus,
490 changed the unsigned char *auth_data to void *auth_data;
492 * Fixed SHUTDOWN command to send the reply before the server
493 is shutdown. :) Affected file silcd/command.c.
495 * Fixed fatal bug in CONNECT command. The hostname was invalid
496 memory and server crashed. Affected file silcd/command.c.
498 * Fixed fatal bug in CLOSE command. The server_entry became
499 invalid but was referenced later in the command. Affected file
502 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Fixed fatal bug in failure packet handling. Server ignored
505 the failure and thus crashed when it came.
509 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
512 that the command may be executed only once in (about) 2 seconds.
513 The old SILC_CF_LAG flag is same but allows command bursts up
514 to five before limiting.
516 Added the support for CF_LAG and CF_LAG_STRICT flags to the
517 server code. Various commands now includes the CF_LAG_STRICT
518 flag to disallow any kind of miss-use of the command.
520 * Fixed the silc_buffer_unformat to not to allocate any data
521 if the length of the data is zero. It used to allocate the
522 length + 1. Affected file lib/silcutil/silcbuffmt.c.
524 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Changed the format of AdminConnection configuration section
527 in the server. Added username of the admin to the format.
528 Affected files silcd/serverconfig.[ch].
530 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
531 to return admin configuration data by host, username and/or
534 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Implemented WHOWAS command to the server. Added the functions:
538 silc_server_command_whowas_parse,
539 silc_server_command_whowas_send_reply,
540 silc_server_command_whowas_from_client and
541 silc_server_command_whowas_from_server
543 * Added <Client ID> argument to the WHOWAS command reply. Updated
544 the protocol specs accordingly.
546 * Implemented WHOWAS command and command_reply to the client
549 Implemented the WHOWAS printing on the user interface.
551 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Added new argument to the WHOWAS command reply, the real name.
554 It is an optional argument. Updated the protocol specs.
556 * Added SilcIDCacheDestructor callback that is registered when
557 the SilcIDCache is allocated. The callback is called when
558 an cache entry in the ID Cache expires, or is purged from the
559 cache. Added into lib/silccore/idcache.[ch].
561 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
562 to destruct the client entries when the cache entry expires.
563 Other ID Cache's in server and in the client library ignores
566 * If the ID Cache entry's `expire' field is zero then the entry
567 never expires. Added boolean `expire' argument to the
568 silc_idcache_add function in the lib/silccore/idcache.[ch].
569 If it is TRUE the default expiry value is used.
571 * Added silc_server_free_client_data_timeout that is registered
572 when client disconnects. By default for 5 minutes we preserve
573 the client entry for history - for WHOWAS command.
575 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Added support to the server to enforce that commands are not
578 executed more than once in 2 seconds. If server receives
579 commands from client more frequently, timeout is registered
580 to process the commands. Affected file silcd/command.c.
581 Added new function silc_server_command_process_timeout.
583 * Changed NICK_NOTIFY handling in client library to check that
584 if the client's nickname was changed, so there is no need to
585 resolve anything from the server.
587 * Removed error printing from the WHOIS and IDENTIFY commands.
588 If error occurs then it is ignored silently in the client library.
589 The application, however, may map the received error to
590 human readable error string. The application currently maps
591 the NO_SUCH_NICKNAME error to string.
593 * Made the command status message public to the application. Moved
594 them from lib/silcclient/command_reply.c to
595 lib/silcclient/command_reply.h. The application can map the
596 received command status to the string with the
597 silc_client_command_status_message function.
599 * Added check to the server to check that client's ID is same
600 as the Source ID in the packet the client sent. They must
603 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
605 * Added dist-bzip hook to the Makefile.am to make bzip2
606 compressed distributions.
608 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Server now enforces the maximum length for the nickname and
611 the channel as protocol specification dictates. 128 bytes for
612 nickname and 256 bytes for channel name.
614 * Moved the WHOIS printing to the application. The client libary
615 does not print out the WHOIS information anymore, the application
616 must do it. Renamed silc_client_command_reply_whois_print to
617 the silc_client_command_reply_whois_save.
619 The client's idle time is also sent to the application now, and
620 the idle is shown on screen.
622 * Added silc_client_command_reply_identify_save to save the
623 received IDENTIFY entries.
625 * Do not check for channel private keys in message sending and
626 reception if the channel does not have the PRIVKEY mode set.
627 Affected file lib/silclient/client_channel.c.
629 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
632 just surfaced after chaning the JOIN procedure.
634 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Added silc_client_get_clients_by_list to get client entries
637 from Client ID list, that is returned for example by JOIN
638 and USERS command replies. The application should use this
639 function for example when JOIN command reply is received to
640 resolve the clients already on the channel (library does not
641 do that anymore as USERS command reply is not used in the JOIN
642 procedure anymore). Affected files lib/silcclient/silcapi.h and
643 lib/silcclient/idlist.c.
645 * JOIN command reply and USERS command reply returns now SilcBuffer
646 pointers instead of unsigned char pointers when returning
647 the client list and mode list.
649 * Added <Client ID> argument to the JOIN command reply, mainly
650 for the server to identify for which client the command was
651 originally sent. Updated protocol specs accordingly.
653 * Added SilcDlist private_key pointer to the SilcChannelEntry
654 in the client to support the channel private keys. Affected
655 file is lib/silcclient/idlist.h.
657 * Added SilcChannelPrivateKey argument to the function
658 silc_client_send_channel_message so that application can choose
659 to use specific private ke if it wants to. If it is not provided,
660 the normal channel key is used, unless private keys are set.
661 In this case the first (key that was added first) is used
662 as the encryption key.
664 * Implemented the support for channel private key handling.
665 Implemented the following functions:
667 silc_client_add_channel_private_key,
668 silc_client_del_channel_private_keys,
669 silc_client_del_channel_private_key,
670 silc_client_list_channel_private_keys and
671 silc_client_free_channel_private_keys
673 Affected file lib/silcclient/client_channel.c.
675 * Added the support for the private keys in the channel message
676 sending and encryption and in the message reception and
677 decryption. Affected funtions are
678 silc_client_send_channel_message and silc_client_channel_message.
680 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Added SKE's key verify callback to the client library's
683 KE protocol context. Affected files lib/silcclient/protocol.[ch].
685 * Removed the statement that server (or router) must send USERS
686 command reply when joining to the channel so that the client
687 knows who are on the channel. Instead, the client list and
688 client's mode list is now sent in the JOIN command reply to the
689 client who joined channel. This is better solution.
691 * Added function silc_server_get_users_on_channel and function
692 silc_server_save_users_on_channel to the silcd/server.[ch].
694 * Removed function silc_server_command_send_users from the
697 * Do not show topic on the client library anymore. The topic is
698 sent in the command reply notify to the application and the
699 application must show the topic now.
701 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Added client searching by nickname hash into the IDENTIFY and
704 WHOIS commands in the server as they were clearly missing from
705 them. Affected file is silcd/command.c.
707 * Fixed a bug in private message receiving in the client library.
708 The remote ID was freed and it wasn't supposed, now it is
711 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Minor fix to the channel payload; allocate the data area, as it
714 needs to be of specific length.
716 * If the key agreement port is zero then the operating
717 system will define the bound port. Affected files are
718 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
720 * Added new function silc_channel_payload_decrypt into the file
721 lib/silccore/silcchannel.[ch].
723 * Moved the channel message etc, check from silc_packet_decrypt
724 to applications. The library calls now a generic
725 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
726 when the packet is either normal or special. This was done to
727 allow more wide range of checking that was not allowed when
728 the code was in library. Now applications can do virtually any
729 checks to the packet and return to the library the decision how
730 the packet should be processed. Affected files are
731 lib/silccore/silcpacket.[ch].
733 Added silc_server_packet_decrypt_check to the server and
734 silc_client_packet_decrypt_check to the client library.
736 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
737 to send with specified source and destination information.
739 * Channel message delivery between routers was broken after the
740 channel key distribution was fixed earlier. The channel key
741 was used be to distributed to other routers as well which is not
742 allowed by the protocol. Now this is fixed and channel keys
743 really are cell specific and the channel message delivery between
744 routers comply with the protocol specification.
746 * Fixed various commands in server to check also the global list
747 for the channel entry and not just the local list. The affected
748 file silcd/command.c.
750 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Added assert()s to buffer formatting and unformatting routines
753 to assert (if --enable-debug) when error occurs. Affected
754 file: lib/silcutil/silcbuffmt.c.
756 * Changed to auto-reconnect to check whether the remote host is
757 router and register the re-connect timeout if it is. It used
758 to check that whether we are normal server, but router must do
759 auto-reconnect with another router as well. Affected file
762 * Removed the [<key len>] option from CMODE command as the cipher
763 name decides the key length, nowadays. See the defined ciphers
764 from the protocol specification.
766 * Added [<hmac>] option to the CMODE command to define the HMAC
767 for the channel. Added SILC_CMODE_HMAC channel mode.
769 * Added [<hmac>] option for the JOIN command so that user can
770 select which HMAC is used to compute the MACs of the channel
773 * Added Hmac field to the Channel Message Payload. The integrity
774 of plaintext channel messages are now protected by computing
775 MAC of the message and attaching the MAC to the payload. The
776 MAC is encrypted. Now, it is clear that this causes some
777 overhead to the size of the packet but rationale for this is that
778 now the receiver can verify whether the channel message decrypted
779 correctly and also when private keys are set for the channel the
780 receiver can decrypt the packet with several keys and check from
781 the MAC which key decrypted the message correctly.
783 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
784 lib/silccrypt/silccipher.[ch].
786 * Added silc_hash_len to return the digest length into the
787 lib/silcrypt/silchash.[ch].
789 * Rewrote parts of Silc Channel Payload interface in the
790 lib/silccore/silcchannel.[ch]. The encode function now also
791 encrypts the packet and parse function decrypts it.
793 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Fixed a minor formatting bug in the SKE's key material processing.
796 It actually might have processed the keys wrong way resulting
799 * Redefined the mandatory HMAC algorithms and added new algorithms.
800 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
801 and hmac-md5 truncated to 96 bits. The mandatory is now
802 hmac-sha1-96. Rest are optional (including the one that used
803 to be mandatory). Rationale for this is that the truncated HMAC
804 length is sufficient from security point of view and can actually
805 make the attack against the HMAC harder. Also, the truncated
806 HMAC causes less overhead to the packets. See the RFC2104 for
809 * Added new [hmac] configuration section. The SKE used to use
810 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
811 is of course wrong. The official names that must be proposed in
812 the SKE are the ones defined in the protocol specification
813 (hmac-sha1-96 for example). The user can configure any hmac
814 using any hash function configured in the [hash] section. At
815 least, the mandatory must be configured.
817 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
819 * Added HMAC list to the SKE proposal list. It has now both
820 hash algorithm list and HMAC list. This makes the protocol
821 incompatible with previous versions. The SKE now seems to work
822 the way it is supposed to work, for the first time actually.
824 * Defined plain Hash algorithms to the protocol specification.
827 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Implemented support for key agreement packets into the server.
830 Added functions silc_server_key_agreement and
831 silc_server_send_key_agreement. Other than these functions,
832 server has nothing to do with this packet.
834 * Added support for private message key packets into the server.
835 Added functions silc_server_private_message_key and
836 silc_server_send_private_message_key.
840 * Changed the silc_[client|server]_protocol_ke_set_keys to be
841 called in the protocol's final callback instead in the END
842 protocol state. This makes a little more sense and in the same
843 time in client we can use the same protocol routines for normal
844 key exchange and to key agreement packet handling as well.
846 * Added to both client's and server's KE protocol context the
847 SilcSKEKeyMaterial pointer to save the key material. We will
848 bring the key material to the protocol's final callback by doing
849 this. The final callback must free the key material.
851 * Added SKE's packet_send callback into client's KE protocol
852 context so that the caller can choose what packet sending function
853 is used. This way we can use different packet sending when
854 doing normal SKE when doing key agreement packet handling (in
855 the key agreement packet handling we do not want to encrypt
858 * Implemented the responder side of the key agreement routines
859 in the client. The client can now bind to specified port and
860 accept incoming key negotiation. The key material is passed
861 to the application after the protocol is over.
863 * Implemented the processing of incoming Key Agreement packet
864 in the client. Added function silc_client_key_agreement to
867 * Implemented the intiator side of the key agreement routines
868 in the client. The client can now initiate key agreement with
869 another remote client. The key material is passed to the
870 application after the protocol is over.
872 * Created client_keyagr.c to include all the key agreement
875 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
876 SILC_TASK_CALLBACK except that it is not static.
878 * Created client_notify.c and moved the Notify packet handling
879 from the client.[ch] into that file.
881 * Created client_prvmsg.c and moved all private message and
882 private message key routines from the client.[ch] into that file.
884 * Create client_channel.c and moved all channel message and
885 channel private key routines from the client.[ch] into that file.
887 * Changed silc_client_get_client_by_id_resolve to resolve with
888 WHOIS command instead of IDENTIFY command, in the file
889 lib/silclient/idlist.c.
891 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Implemented the SKE's responder side to the Client library.
895 * When FAILURE is received to the protocol do not trust it
896 blindly. Register a timeout to wait whether the remote closes
897 the connection as it should do it, only after that process the
898 actual failure. This was changed to both client and server.
900 * Added client_internal.h to include some of the structures
901 there instead of client.h in lib/silcclient/.
903 * Added function silc_task_unregister_by_callback to unregister
904 timeouts by the callback function.
906 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Some "Incomplete WHOIS info" errors has been appearing on the
909 log files. Took away the entry->userinfo check from WHOIS
910 reply sending. The entry->userinfo is now " " if client did not
911 provide one. I thought this was fixed earlier but something
912 is wrong still. Let's see if the error still appears.
914 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Fixed a minor bug in the login when the channel key is
917 re-generated in the server. It used to generate the key in
918 wrong order and thus caused problems in the channel traffic.
920 * Fixed a minor bug in channel key distsribution after
921 KICK command. The key was not sent to the router even though
924 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added silc_ske_process_key_material_data as generic routine
927 to process any key material as the SILC protocol dictates. The
928 function is used by the actual SKE library but can be used by
929 applications as well. This relates to the private message keys
930 and the channel private keys since they must be processed the
931 same way the normal SILC session keys. The protocol dictates
932 this. Affected files: lib/silcske/silcske.[ch].
934 Added also silc_ske_free_key_material to free the
935 SilcSKEKeyMaterial structure.
937 * Defined silc_cipher_set_key function to set the key for
938 cipher without using the object's method function. The affected
939 files: lib/silccrypt/silccipher.[ch].
941 * Implemented silc silc_client_add_private_message_key,
942 silc_client_add_private_message_key_ske,
943 silc_client_del_private_message_key,
944 silc_client_list_private_message_keys and
945 silc_client_free_private_message_keys functions in the
948 Added functions silc_client_send_private_message_key to send
949 the Private Message Key payload and silc_client_private_message_key
950 to handle incoming Private Message Key payload.
952 * Added Cipher field to the Private Message Key payload to set
953 the cipher to be used. If ignored, the default cipher defined
954 in the SILC protocol (aes-256-cbc) is used.
956 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Removed lib/silcclient/ops.h file.
960 Redefined parts of the SILC Client Library API. Created new
961 file silcapi.h that deprecates the ops.h file and defines the
962 published Client Library API. Defined also private message key
963 API and channel private key API into the file.
965 This is the file that the application must include from the
966 SILC Client Library. Other files need not be included by
967 the application anymore.
969 * Added new key_agreement client operation callback and also
970 defined the Key Agreement library API for the application.
972 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
975 is used by clients to request key negotiation between another
976 client in the SILC network. If the negotiation is started it
977 is performed using the SKE protocol. The result of the
978 negotiation, the secret key material, can be used for example
979 as private message key.
981 Implemented the Key Agreement payload into the files
982 lib/silccore/silauth.[ch].
984 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Redefined ciphers for the SILC protocol. Added some new ciphers
987 and defined the key lengths for the algorithms. Changed the
988 code accordingly. The default key length is now 256 bits.
990 * Fixed SKE key distribution function silc_ske_process_key_material
991 when the key length is more than 128 bits. The default key
992 length in SILC is now 256 bits.
994 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
995 to indicate unsupported algorithm.
997 * Renamed rijndael.c to aes.c and all functions as well.
999 * Fixed a long standing channel key setting bug in client library.
1000 Weird that it has never surfaced before.
1002 * Fixed bug in channel deletion. If the entire channel is removed
1003 then it must also delete the references of the channel entry
1004 from the client's channel list as the client's channel entry and
1005 the channel's client entry share same memory.
1007 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Implemented CONNECT and SHUTDOWN commands in the client.
1011 * Implemented CLOSE command to the client.
1013 * Added the function silc_idlist_find_server_by_name into the
1014 files silcd/idlist.[ch].
1016 Added the function silc_idlist_find_server_by_conn into the
1017 files silcd/idlist.[ch].
1019 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * DIE command was renamed to SHUTDOWN. Updated the both code
1024 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1025 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1027 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1030 * Added function silc_server_create_connection function to create
1031 connection to remote router. My server implementation actually
1032 does not allow router to connect to normal server (it expects
1033 that normal server always initiates the connection to the router)
1034 so the CONNECT command is only good for connecting to another
1037 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1040 or some other client was kicked from the channel.
1042 Implemented the handling of the notify type to both client
1045 Implemented silc_server_send_notify_kicked to send the KICKED
1046 notify. It is used to send it to the server's primary router.
1048 * Implemented the KICK command into server and client.
1050 * Added `query' argument to the silc_idlist_get_client function
1051 to indicate whether to query the client from server or not if
1054 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1055 to indicate that the client is not channel founder.
1059 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Removed the rng context from SilcPacketContext structure and
1062 changed that the packet routine uses the Global RNG API.
1064 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added support for quit message that client can "leave" on the
1067 channel when it quits the SILC. It is ditributed inside the
1068 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1070 Added silc_server_free_client_data that will take the
1071 signoff message as argument.
1073 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1075 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Updated parts of the protocol specification to keep it up
1080 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1082 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1083 payloads in one packet.
1085 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1086 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1087 use now the new List flag.
1089 * Also deprecated the following packet types: REPLACE_ID,
1090 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1092 * Added list support for Notify packet in server.
1094 * Added silc_server_send_notify_channel_change to send the
1095 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1096 the silc_server_send_replace_id.
1098 * Added silc_server_send_notify_nick_change to send the
1099 NICK_CHANGE notify type. Deprecates the function
1100 silc_server_send_replace_id.
1102 * Added silc_server_send_notify_join to send the JOIN notify type.
1103 Deprecates the function silc_server_send_new_channel_user.
1105 * Added silc_server_send_notify_leave to send LEAVE notify type.
1106 Deprecates the function silc_server_send_remove_channel_user.
1108 * Added silc_server_send_notify_cmode and
1109 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1110 types. Deprecates the silc_server_send_set_mode function.
1112 * Added SERVER_SIGNOFF notify type to indicate that server has
1113 quit. This means that all clients on the channel from that
1114 server will drop. This can be also used when netsplit happens.
1116 Deprecated REMOVE_ID packet type since it is not needed anymore
1119 Added silc_server_send_notify_server_signoff to send the
1120 SERVER_SIGNOFF notify type. Deprecates the function
1121 silc_server_send_remove_id.
1123 Added also silc_server_send_notify_signoff to send the
1124 SIGNOFF notify type.
1126 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1127 SILC protocol from this day on. Changed the protocol
1128 specification as well.
1130 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1131 notify type. It is used between routers to notify about
1132 topic changes on a channel.
1134 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1137 * Partly updated the protocol specification to comply with the
1138 changes now made. It is still though a bit outdated.
1140 * The JOIN notify type now takes one extra argument <Channel ID>.
1141 The packet used to be destined to the channel but now the
1142 JOIN type may be sent as list thus it is impossible to
1143 destine it to any specific channel. By adding this argument
1144 it is again possible.
1146 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Added CREDITS file. The CHANGES and CREDITS file will appear
1149 in the distribution as well.
1151 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1154 types in the server's silcd/packet_receive.c.
1156 * Implemented CMODE and CUMODE to work in router environment.
1158 * Fixed minor encoding and decoding buglet from the
1159 lib/silccore/silcmode.c.
1161 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1164 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1166 * Changed all SilcConfigServer* and silc_config_server* to
1167 SilcServerConfig* and silc_server_config*, respectively.
1170 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Associated the ID (client or server ID) to the Authentication
1173 Payload to avoid any possibility of forging. Updated the
1174 protocol specification and the code accordingly.
1176 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * The RSA key length is now save to the RsaKey context in the
1179 key generation process in lib/silccrypt/rsa.c. The key length
1180 is now used to figure out the maximum size of the block allowed
1181 to be encrypted/signed.
1183 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1184 is equivalent to the silc_mp_mp2bin but does not allocate any
1187 * Changed silc_mp_mp2bin API to take length argument. If it is
1188 non-zero then the buffer is allocated that large. If zero, then
1189 the size is approximated using silc_mp_sizeinbase, which however
1192 * Created Global RNG API which is global RNG that application can
1193 initialize. After initializing, any routine anywhere in the
1194 code (including library) can use RNG without allocating a new
1195 RNG object. This was done to allow this sort of use of the
1196 RNG in code that has no chance to allocate RNG object. All
1197 applications currently allocate this and many routines in the
1198 library use this. Affected file lib/silccrypt/silcrng.[ch].
1200 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1201 it to use the Global RNG API.
1203 * Defined Authentication Payload into protocol specification that
1204 is used during SILC session to authenticate entities. It is
1205 used for example by client to authenticate itself to the server
1206 to obtain server operator privileges.
1208 Implemented this payload into the lib/silccore/silcauth.[ch].
1209 Implemented also routines for public key based authentication
1210 as the new protocol specification dictates.
1212 Moved definitions of different authentication methods from
1213 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1215 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1216 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1217 silc_pkcs_verify_with_hash functions into the file
1218 lib/silccrypt/silcpkcs.[ch].
1220 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * The client entry's userinfo pointer must be always valid.
1223 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1224 will fail since it requires the userinfo. Now, the userinfo
1225 is allocated as "" if actual userinfo does not exist. Actually,
1226 it must exist and it is totally Ok to drop client connections
1227 that does not announce the userinfo. However, we will make
1228 this workaround for now.
1230 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1231 to return the remote port by socket.
1233 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1236 SILC_SERVER_PENDING_EXEC and added an new macro
1237 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1238 data or when error occurs while processing the pending command.
1240 Added new argument `destructor' into silc_server_command_pending
1241 and to the SilcServerCommandPending object. This destructor is
1242 now called after calling the pending callback or if error occurs
1243 immediately. If error occurs the actual pending callback won't
1244 be called at all - only the destructor. The destructor may be
1245 NULL if destructor is not needed.
1247 All this applies for client library code as well. Similar
1248 changes were made there as well for the pending commands.
1250 In the client, the application must now allocate the
1251 SilcClientCommandContext with the silc_client_command_alloc
1254 * Added reference counter to the SilcServerCommandContext. Added
1255 function silc_server_command_alloc and silc_server_command_dup
1258 Same type of functions added to the client library for the same
1261 * Removed the cmd_ident from IDListData away since it is now
1262 global for all connections. It is the command identifier used
1263 in command sending and with pending commands. The affected file
1266 * Added reference counter to the SilcSocketConnection objecet to
1267 indicate the usage count of the object. The object won't be
1268 freed untill the reference counter hits zero. Currently only
1269 server uses this, and client ignores it. The client must be
1270 set to use this too later. The affected files are
1271 lib/silccore/silcsockconn.[ch]. Added also the function
1272 silc_socket_dup to increase the reference counter.
1274 This was mainly added because it is possible that the socket
1275 is removed underneath of pending command or other async
1276 operation. Now it won't be free'd and proper DISCONNECTING
1277 flags, etc. can be set to avoid sending data to connection that
1278 is not valid anymore.
1280 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1281 the connection. After that it sets SILC_SET_DISCONNECTED.
1282 It is, however, possible that the socket data is not still freed.
1283 The silc_server_packet_process now checks that data is not
1284 read or written to connection that is DISCONNECTED. The socket
1285 get's freed when the reference counter hits zero.
1287 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Changed the client operation API: channel_message operation's
1290 `sender' is now the client entry of the sender, not the nickname
1291 and the `channel' is the channel entry, not the channel name.
1293 In the private_message operation the `sender' is now also the
1294 client entry of the sender not the nickname.
1296 Affected file is lib/silcclient/ops.h and all applications
1297 using the client operations.
1299 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Moved the calling of ops->connect() from connect_to_server_final
1302 into receive_new_id functin since that is the point when the
1303 client is actually allowed to send traffic to network. The
1304 affected file is lib/silcclient/client.c.
1306 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1309 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1310 (if needs broadcasting) instead of broadcasting the packets one
1311 by one which would make a burst in the network traffic.
1313 * Added `broadcast' argument to the functions in silcd/server.[ch]
1314 silc_server_create_new_channel[_with_id] to indicate whether
1315 to send New Channel packet to primary router.
1317 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added new function into the silcd/server.[ch] files:
1320 silc_server_create_new_channel_with_id to create new channel with
1321 already existing Channel ID.
1323 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1324 lib/silccore/silcpacket.h. This packet is used t send list of
1325 Set Mode payloads inside one packet. Server uses this to set
1326 the modes for the channels and clients on those channels, that it
1327 announced to the router when it connected to it. The protocol
1328 specification has been updated accordingly.
1330 * The silc_server_new_channel did not handle the packet coming
1331 from normal server as it normally does not send that. However,
1332 when it announces its channels it does send it. Implemented
1333 the support for that.
1335 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1336 into the file lib/silccore/id.h.
1338 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1340 * Fixed memory leaks in the functions silc_idlist_del_client,
1341 silc_idlist_del_channel and silc_idlist_del_server in the file
1342 silcd/idlist.c. All of those leaked like a sieve.
1344 * Fixed some small memory leaks in the client's function
1345 silc_client_notify_by_server.
1347 * Added functions into silcd/server.c: silc_server_announce_clients,
1348 silc_server_announce_channels and silc_server_announce_server.
1349 These functions are used by normal and router server to announce
1350 to its primary router about clients, channels and servers (when
1351 router) that we own. This is done after we've connected to the
1354 These functions effectively implements the following packet types:
1355 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1356 and SILC_PACKET_NEW_ID_LIST.
1358 * Added new functions into the silcd/packet_receive.[ch]:
1359 silc_server_new_id_list, silc_server_new_channel_list and
1360 silc_server_new_channel_user_list to handle the incoming
1361 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1363 * Added support of changing Channel ID in the function
1364 silc_server_replace_id. If the server that announces a channel
1365 to the router already exists in the router (with same name but
1366 with different Channel ID), router is responsible to send
1367 Replace ID packet to the server and force the server to change
1368 the Channel ID to the one router has.
1370 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1371 client that the Channel ID has been changed by the router. The
1372 normal server sends this to the client. Client must start using
1373 the new Channel ID as the channel's ID.
1375 Implemented handling of this new type into lib/silcclient/client.c
1376 into the function silc_client_notify_by_server.
1378 * Added new function silc_idlist_replace_channel_id into the files
1379 silcd/idlist.[ch] to replace the Channel ID.
1381 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Call silc_server_command_identify_check always when processing
1384 the IDENTIFY command in silcd/command.c
1386 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1389 send keepalive packets. The packet can be sent by clients,
1390 servers and routers.
1392 Added function silc_socket_set_heartbeat into the file
1393 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1394 If not set, the heartbeat is not performed. The actual
1395 heartbeat is implemented in the low level socket connection
1396 library. However, application is responsible of actually
1399 Added silc_server_send_heartbeat to send the actual heartbeat
1400 packet into silcd/packet_send.[ch]. Server now performs
1401 keepalive with all connections.
1403 * Added silc_task_get_first function into lib/silcutil/silctask.c
1404 to return the timeout task with shortest timeout. There was a bug
1405 in task unregistration that caused problems. TODO has been
1406 updated to include that task system must be rewritten.
1408 * The client library will now resolve the client information when
1409 receiving JOIN notify from server for client that we know but
1410 have incomplete information.
1412 * Rewrote parts of silc_server_remove_from_channels and
1413 silc_server_remove_from_one_channel as they did not remove the
1414 channel in some circumstances even though they should've.
1416 * Encryption problem encountered in server:
1418 The LEAVE command used to send the Channel Key packet to the
1419 router immediately after generating it. However, the code
1420 had earlier sent Remove Channel user packet but not immediately,
1421 ie. it was put to queue. The order of packets in the router
1422 was that Channel Key packet was first and Remove Channel User
1423 packet was second, even though they were encrypted in the
1424 reverse order. For this reason, MAC check failed. Now, this
1425 is fixed by not sending the Channel Key packet immediately but
1426 putting it to queue. However, this is more fundamental problem:
1427 packets that are in queue should actually not be encrypted
1428 because packets that are sent immediately gets encrypted
1429 actually with wrong IV (and thus MAC check fails). So, packets
1430 that are in queue should be encrypted when they are sent to
1431 the wire and not when they put to the queue.
1433 However, the problem is that the current system has not been
1434 designed to work that way. Instead, the packet is encrypted
1435 as soon as possible and left to the queue. The queue is then
1436 just purged into wire. There won't be any fixes for this
1437 any time soon. So, the current semantic for packet sending
1440 o If you send packet to remote host and do not force the send
1441 (the packet will be in queue) then all subsequent packets to the
1442 same remote host must also be put to the queue. Only after the
1443 queue has been purged is it safe again to force the packet
1446 o If you send all packets immediately then it safe to send
1447 any of subsequent packets through the queue, however, after
1448 the first packet is put to queue then any subsequent packets
1449 must also be put to the queue.
1451 Follow these rules and everything works fine.
1453 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added new function silc_server_remove_clients_by_server to
1456 remove all client entries from ID list when the server connection
1457 is lost. In this case it is also important to invalidate all
1458 client entires as they hold the invalid server entry. This
1459 fixes fatal bug when server has lost connection and will reconnect
1462 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Made some sanity checks to silc_server_daemonise like to check
1465 whether the requested user and group actually exists.
1467 * Added sanity check to SKE's silc_ske_responder_finish to check
1468 that the public and private key actually is valid.
1470 * Invalidate the client's nickname when receiving Replace ID
1471 packet and the Client ID is being replaced. This means that the
1472 server will query the nickname if someone needs it (client)
1475 * Sort the ID Cache in client library when the ID Cache data
1476 has changed (needs sorting).
1478 * Do not allow for SILC client to create several connections to
1479 several servers. The client does not support windows right now
1480 and generating multiple connections causes weird behaviour.
1482 Irssi-silc client does support windows and can handle several
1483 connections without problems, see: www.irssi.org and SILC plugin.
1485 * Fixed some places where client was added to the IDList. The
1486 rule of thumb is following (in order to get everything right):
1487 If the client is directly connected local client then the
1488 `connection' argument must be set and `router' argument must be
1489 NULL to silc_idlist_add_client function. If the client is not
1490 directly connected client then the `router' argument must
1491 bet set and the `connection' argument must be NULL to the
1492 silc_idlist_add_client function.
1494 * The funtion silc_server_packet_send_local_channel actually did
1495 not check whether the client was locally connected or not. It
1496 does that now. Fixed a bug related to LEAVE command.
1498 * Fixed Remove Channel User payload parsing bug in server's
1499 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1501 * The server's silc_server_save_channel_key now checks also the
1502 global ID list for the channel as it might not be in the local
1503 list. Fixed a bug related to LEAVE command.
1505 * Is this the end of the [<unknown>] buglet that has been lurking
1506 around for a long time? A little for loop fix in server's
1507 silc_server_command_whois_parse that is used by both IDENTIFY
1508 and WHOIS command. At least, this was a clear bug and a cause
1509 of one type of [<unknown>] buglet.
1511 * WHOIS and IDENTIFY commands call the function
1512 silc_server_command_[whois/identify]_check function even if
1513 we are not router server.
1515 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Added --with-gmp configuration option. If set the GMP
1518 is always compiled in the SILC source tree. If not set then
1519 it is checked whether the system has the GMP3 installed. If
1520 it has then the GMP won't be compiled (the system's headers
1521 and library is used), if it doesn't have it then the GMP is
1522 compiled in the SILC source tree.
1524 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Changed RSA private exponent generation to what PKCS #1
1527 suggests. We try to find the smallest possible d by doing
1528 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1529 not security fix but optimization.
1531 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Added new config entry [Identity] to fork the server and run
1534 it as specific user and group. A patch from Bostik.
1536 * Imported Dotconf configuration library into lib/dotconf.
1537 This will be used to create the SILC configuration files later.
1538 It will appear in the distsribution after this commit.
1540 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * A big code auditing weekend happening. Auditing code for
1543 obvious mistakes, bugs and errors. Also, removing any code
1546 Removed files for being obsolete:
1548 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1549 inline in the file lib/silcutil/silcbuffer.h)
1551 o lib/silcutil/silcbufutil.c (the header has inline versions)
1553 Changed code to fix possible error conditions:
1555 o The buffer formatting routines now check that the destination
1556 buffer really has enough space to add the data. This applies for
1557 both buffer formatting and unformatting
1558 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1559 unformatting was changed to accomodate following rules:
1560 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1561 sent to the function while XXX_*STRING will not allocate or copy
1562 the data into the buffer. Instead it sets the pointer from the
1563 buffer into the pointer sent as argument (XXX_*STRING used to
1564 require that the pointer must be allocated already). This change
1565 makes this whole thing a bit more consistent and more optimized
1566 (note that the data returned in the unformatting with XXX_*STRING
1567 must not be freed now). The routines return now -1 on error.
1569 o Tried to find all code that use buffer_format and buffer_unformat
1570 and added return value checking to prevent formatting and
1571 especially unformatting errors and possible subsequent fatal
1574 o Changed ske->x and ske->KEY to mallocated pointers in
1575 lib/silcske/silcske.h. Fixed possible data and memory leak.
1577 o Added return value checking to all *_parse* functions. Fixed
1578 many memory leaks as well.
1580 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1581 so that buffer overflows would not happen. All code now also
1582 checks the return value as it can fail.
1584 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Added reconnection support to server if the normal server looses
1587 its connection to the router (for example if router is rebooted).
1588 The server performs normal reconnection strategy implemented
1589 to the server. Affected file silcd/server.c.
1591 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Added new packet type SILC_PACKET_SET_MODE that is used to
1594 distribute the information about changed modes (for clients,
1595 channels and clients channel modes) to all routers in the
1596 network. Updated the protocol specification accordingly.
1598 Added functions into silcd/packet_send.c and
1599 silcd/packet_receive.c: silc_server_send_set_mode,
1600 silc_server_set_mode.
1602 Added new files silcmode.[ch] into lib/silccore that implements
1603 the encoding and decoding of Set Mode Payload. Added new type
1604 SilcSetModePayload. Moved the definitions of different modes
1605 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1607 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Oops, a little mistake in server's connection authentication
1610 protocol. The protocol is not ended with FAILURE but with
1611 SUCCESS if the authentication is Ok. :) Affected file is
1614 * Implemented NICK_CHANGE notify handling in server in the file
1615 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1616 the local clients on the channel. After the changing nickname
1617 in router environment snhould work and the [<unknown>] nickname
1618 should appear no more.
1620 The silc_server_replace_id function that receives the Replace ID
1621 payload now sends the NICK_CHANGE notify type also in the file
1622 silcd/packet_receive.c
1624 * Changed WHOIS and IDENTIFY command to support the maximum amount
1625 of arguments defined in protocol specs (3328 arguments). This
1626 fixed a bug that caused problems when there were more than three
1629 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added extra parameter, command identifier, to the
1632 silc_client_send_command so that explicit command identifier
1635 Changed that ID list routines uses specific command identifier
1636 when sending WHOIS/IDENTIFY requests to the server so that they
1637 can be identified when the reply comes back.
1639 Affected files lib/silcclient/command.[ch],
1640 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1642 * Added `sender' argument to silc_server_packet_send_to_channel
1643 to indicaet the sender who originally sent the packet to us
1644 that we are now re-sending. Ignored if NULL. Affected file
1645 silcd/packet_send.[ch].
1647 * Added some server statistics support in silcd/server_internal.h
1648 SilcServerStatistics structure and around the server code. Also
1649 send some nice statistics information when client is connecting
1652 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * Fixed channel ID decoding in server's JOIN command reply in
1655 silcd/command_reply.c
1657 * Fixed braodcasting of replace ID payload to not to send it if
1658 we are standalone server in silcd/packet_receive.c.
1660 * Fixed all channel message sending routines to not to send
1661 packets to clients that has router set, since they are routed
1662 separately in the same function earlier. Affects file
1663 silcd/packet_send.c and all channel packet sending functions.
1665 * In USERS reply, res_argv[i] are not allocated, the table
1666 is allocated. Thus changed that free the table, not its
1669 * In server's whois_check and identify_check if the client is
1670 locally connected do not send any WHOIS commands - they are not
1673 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Fixed some minor bugs in client when sending WHOIS command. The
1676 arguments was in wrong order.
1678 * Removed statis function add_to_channel from server in
1679 silcd/command.c that was previously used with the joining but
1682 * Tested USERS command in router environment successfully with two
1683 routers, two servers and two clients.
1685 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Reorganized the USERS command and command reply in client library
1688 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1689 When the command is given by user we register a pending command
1690 callback that will reprocess the command after the reply has been
1691 received from the server. When reprocessing the packet we then
1692 display the information. Thus, the USERS information is displayed
1693 now in the command callback instead of in the command reply
1694 callback. The processing of the command is same as previously
1695 when server has sent the command reply in the JOINing process.
1697 * Added to USERS command in silcd/command_reply.c to join the client,
1698 we didn't use to know about, to the channel after we've created
1699 a client entry for it. Also, for clienet we did know already still
1700 check whether it is on the channel or not and add it if not.
1702 * Removed silc_server_command_join_notify as the function and its
1705 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Changed the client's pending command handling to the same as the
1708 server's pending command handling. It is also now possible to
1709 execute command reply functions from other command reply
1710 function as the function callbacks for commands and command
1711 replies are one and same. The pending commands are not static
1712 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1713 in client connection context. Thus, pending commands are server
1714 connection specific as it is convenient.
1716 Changed the function silc_client_command_pending and
1717 silc_client_command_pending_del and added new function
1718 silc_client_command_pending_check. Removed the
1719 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1722 * Added cmd_ident, current command identifier, to the client
1723 connection context in lib/silcclient/client.h to keep track on
1724 command identifiers used in command sending. Client's command reply
1725 function handling now supports the mandatory command identifiers.
1727 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1728 funtions in client to fully support pending command callbacks.
1730 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1731 as one of the arguments to the application in the command reply
1734 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1735 before first releasing SILC but came back. Now it is removed again
1736 and should come back nomore. The FORWARDED flag was used only
1737 by the JOINing procedure by forwarding the command packet to router.
1738 Now, the JOINing procedure has been changed to more generic (due
1739 to various router environment issues) and FORWARDED is not needed
1740 anymore for anything. The protocol specification is yet to be
1743 Now, removed silc_server_packet_forward from server and the flag
1744 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1746 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Renamed NAMES command to USERS command. The NAMES was named that
1749 due to historical reasons. Now it is renamed. Also, rewrote
1750 parts of the USERS command. The nickname list is not sent anymore
1751 by the server. Only Client ID and mode lists are sent in the USERS
1752 command. Changed this also to the protocol specification.
1754 The client now resolves the names and stuff after it receives
1755 the USERS list from the server when joining to the channel.
1757 * WHOIS and IDENTIFY commands has been changed to support multiple
1758 Client ID's per command. One can now search for multiple users
1759 in the network by sending only one WHOIS or IDENTIFY command.
1760 Changed the code and the protocol specifications.
1762 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1763 uses silc_server_command_whois_parse to parse the request. */
1765 * If normal server, do not parse the WHOIS and IDENTIFY requests
1766 before sending it to the router. Saves some time.
1768 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Fixed JOIN command on client library. Wrong number of arguments
1771 used to crash the client.
1773 * Added silc_server_channel_has_global function to check whether
1774 channel has global users or not.
1776 * Added silc_server_channel_has_local function to check whether channel
1777 has locally connected clients on the channel.
1779 * The silc_server_remove_from_one_channel now checks whether the
1780 channel has global users or not after given client was removed from
1781 the channel. It also checks whether the channel has local clients
1782 on the channel anymore. If it does not have then the channel entry
1783 is removed as it is not needed anymore.
1785 * The silc_server_notify now checks on JOIN notify whether the joining
1786 client is one of locally connected or global. If it is global then
1787 the channel has now global users on the channel and that is marked
1788 to the channel entry. Also, it now saves the global client to
1789 global list who is joining and JOINs it to the channel. This is
1790 for normal server, that is.
1792 Changed silc_server_send_notify_on_channel,
1793 silc_server_packet_relay_to_channel and
1794 silc_server_packet_send_to_channel check if we are normal server
1795 and client has router set (ie. global client) do not send the
1796 message to that client, as it is already routed to our router.
1798 * Implemented LEAVE notify type handling in silc_server_notify
1801 * Tested LEAVE command in router environment successfully. Tested
1802 with two routers, two servers and two clients.
1806 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1808 * Implemented SIGNOFF notify type handling in silc_server_notify
1811 * silc_server_remove_id now removes the client entry from all channels
1812 it has joined and thusly sends SIGNOFF notify type.
1814 * Rewrote the NAMES list generation in server by removing two excess
1815 loops. The lists are created now inside one loop.
1817 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * silc_server_remove_channel_user checks now also global list
1820 for channel and client.
1822 * silc_server_new_channel_user checks now both local and global
1823 list for channel and client. Fixed a bug in client id decoding.
1824 Used to decode wrong buffer.
1826 * silc_server_channel_message checks now both local and global
1827 list for channel entry.
1829 * Tested channel joining (hence JOIN) in router environment
1830 successfully. Tested with two routers, two servers and two
1833 * Tested channel message sending in router environment successfully.
1835 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Added silc_server_save_channel_key into server.[ch] to save the
1838 received channel key in Channel Key payload processing. It is
1839 also used in JOIN command reply handling.
1841 Equivalent function silc_client_save_channel_key added into
1842 client.[ch] into client library.
1844 * Changed JOIN command reply to send information whether the channel
1845 was created or not (is existing already) and the channel key
1846 payload. Changed protocol specs accordingly.
1848 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1849 the request was sent by ID and not by nickname. Crashed on
1852 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1855 now correctly save the received data.
1857 * silc_server_free_sock_user_data now notifies routers in the
1858 network about entities leaving the network.
1860 At the same time implemented functions silc_server_remove_id
1861 and silc_server_send_remove_id to receive and send REMOVE_ID
1862 packets. The packet is used to notify routers in the network
1863 about leaving entities. The ID removed will become invalid in
1866 * Added function silc_idlist_del_server into server. Removes and
1867 free's server entry from ID list.
1869 * silc_server_private_message function now checks, if we are router,
1870 that the destination ID really is valid ID, naturally.
1872 * In router when NEW_ID packet is received (for new client) the
1873 hash of the Client ID is saved in the ID Cache but the
1874 client->nickname is set to NULL, instead of putting the hash
1877 IDENTIFY command now also checks that client->nickname must be
1878 valid. If it is not if will request the data from the server who
1879 owns the client. Added new function
1880 silc_server_command_identify_check.
1882 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1883 to set the command to already allocated Command Payload.
1885 * Tested private message sending in router environment with two
1886 routers, two servers and two clients. Fixed minor bugs and now
1889 * Fixed segfault from client's NAMES command. Used to crash if
1892 * Forwarded packets must not be routed even if it is not destined
1893 to the receiver. Changed server code comply with this.
1895 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added `require_reverse_mapping' boolean value to ServerParams
1898 structure. If TRUE (not default) the server will require that
1899 the connecting host has fully qualified domain name.
1901 If the reverse mapping is not required and hostname could not be
1902 found the IP address is used as hostname.
1904 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Implemented version string checking to both client and server.
1907 The check is incomplete currently due to the abnormal version
1908 strings used in development version of SILC.
1910 * Changed all command functions in server to use the new
1913 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Changed char *data to unsigned char *data in ID Cache system to
1916 support binary data as ID Cache data. Changed code to support
1917 binary data in lib/silccore/idcache.c.
1919 * Renamed silc_server_packet_relay_command_reply to
1920 silc_server_command_reply as it is normal packet receiving
1921 function. Rewrote the function to accept command replys for
1922 servers and not only for clients.
1924 * Mark remote router always as registered server if we are connecting
1925 to it. Otherwise, commands sent by the router to us are ignored.
1927 * All ID List find routines now returns the ID Cache Entry pointer
1928 as well if requested.
1930 * WHOIS command works now in router environment, tested with two
1931 routers, two servers and two clients.
1933 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1934 in router environment (as it is almost equivalent to WHOIS) but
1935 hasn't been tested thoroughly. Added new functions:
1937 silc_server_command_identify_parse
1938 silc_server_command_identify_send_reply
1939 silc_server_command_identify_from_client
1940 silc_server_command_identify_from_server
1942 * Disabled route cache adding because adding two different ID's with
1943 same IP replaces the old cache entry thus giving wrong route.
1944 The entry->router->connection is always the fastest route anyway
1945 so route cache may not be needed. Of course, new routes maybe
1946 established after receiving the ID when the entry->router->connection
1947 might not be anymore the most optimal.
1949 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Add route cache for received ID for fast routing.
1953 * Added silc_server_packet_route to route received packet on router
1954 that is not destined to us.
1956 * Renamed silc_server_get_route to silc_server_route_get.
1958 * Added id_string and id_string_len fields into SilcServer to
1959 include encoded ServerID for fast comparing without excess
1960 encoding of the ID's.
1962 * Cleaned up WHOIS command on server side. Added following static
1965 silc_server_command_whois_parse
1966 silc_server_command_whois_check
1967 silc_server_command_whois_send_reply
1968 silc_server_command_whois_from_client
1969 silc_server_command_whois_from_server
1971 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1972 arguments in command replies. All command functions should be
1973 updated to use this macro.
1975 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Minor typo fixes on command reply handling on server.
1979 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Added silc_server_command_add_to_channel internal routine to add
1982 the client to the channel after router has created the channel and
1983 sent command reply to the server.
1985 * Added generic silc_server_send_command to send any command from
1988 * Use static buffer with ID rendering instead of duplicating data.
1990 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Fixed a channel user mode bug when joining to a channel server gave
1993 everybody channel founder rights, oops.
1995 * We mark ourselves as the router of the incoming server connection
1996 if we are router ourselves. This way we can check in some packet
1997 sending functions whether it is locally connected server. For
1998 incoming router connections we put NULL.
2000 * For router sending packets locally means now always sending the
2001 packet cell wide; to local clients and local servers. For normal
2002 server sending packet locally means sending it to only local
2005 * Fixed the JOIN command to really work in router environment. If the
2006 channel is created it is always created by the router. Router is
2007 also responsible of making the initial joining to the channel,
2008 sending JOIN notify to the sending server and distributing
2009 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2010 does not exist server doesn't do anything else but forward the
2011 command to the router which performs everything.
2013 * Added silc_server_send_channel_key function to send the Channel Key
2016 * Added silc_server_create_channel_key to create new channel key. The
2017 channel key is now re-generated everytime someone joins or leaves
2018 a channel, as protocol dictates. Note: channel->key_len is the
2021 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2024 packet_receive.[ch] to separate packet sending and receiving
2025 routines. The server.[ch] now includes everything else including
2026 actual packet processing (writing and reading data) and other
2029 Renamed silc_server_private_message_send_internal to
2030 silc_server_send_private_message. The routine is still though
2031 used only to relay private messages as server does not send
2032 private messages itself.
2034 Renamed silc_server_new_channel to silc_server_create_new_channel
2035 and added new function sicl_server_new_channel that handles the
2036 incoming New Channel packet. Added also new sending function
2037 silc_server_send_new_channel to send New Channel Payload.
2039 * Added new function silc_server_notify to process incoming notify
2040 packet to the server/router. Server may then relay the notify
2041 to clients if needed.
2043 * Added new function silc_server_new_channel_user to process incoming
2044 New Channel User packet. Router will redistribute the packet and
2045 send JOIN notify to its local clients and locally connected servers
2046 if needed. Normal server will send JOIN notify to its local client
2047 on same channel when received this packet. Added also corresponding
2048 sending function silc_server_send_new_channel_user to sent the
2051 * Added boolean route argument to send_notif_to_channel and
2052 packet_send_to_channel functions to attempt to route the packet
2053 if it is TRUE and send only locally if it is FALSE.
2055 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * silc_server_replace_id now broadcasts the received replace ID
2058 packet if it is not broadcast packet already. The router must
2059 broadcast to inform other routers about changed ID.
2061 * Added backpointer to server's router into SilcServer context in
2062 silcd/server_internal.h.
2064 * Fixed silc_server_packet_broadcast to send correct broadcast
2067 * The channel key is now distributed to the local client as soon
2068 as it is received from the router (in router environment) so that
2069 no other packet may be sent for the channel until client has
2072 * silc_server_remove_channel_user now broadcasts the received
2073 Remove Channel User packet if it is not broadcast packet already.
2074 The router must broadcast to inform other routers about removed
2077 * Added users field into SilcPacketContext that is a reference count
2078 of the context. One can increase the reference count by calling
2079 silc_packet_context_dup which is now changed to just increase the
2080 reference count instead of duplicating the data. The reference
2081 count is decresed by calling silc_packet_context_free that will
2082 free the data after the reference count hits zero.
2084 For now on the packet context and everything allocated into it
2085 (including the raw packet from network) must be freed by calling
2086 the new silc_packet_context_free function. Added also new function
2087 silc_packet_context_alloc that must be used now to allocate the
2088 context. This also means that if a routine is asynchronous from
2089 silc_[client/server]_packet_parse_type the packet context must
2090 be duplicated by calling silc_packet_context_dup. Otherwise it
2091 gets free'd after silc_[client/server]_packet_parse_type returns.
2092 Also, one must remember that if packet is duplicated then its
2093 reference count must be decresed by calling the free function as
2094 many times as it was duplicated.
2096 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2097 from both client and server.
2099 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Made joining to a channel working in router environment.
2103 * Cleaned up JOIN command on server side and create function
2104 silc_server_command_join_channel internal routine to make the
2107 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Changed silc_command_pending list to SilcDList. Also, added
2110 `ident' field to SilcServerCommandPending structure to identify
2111 the reply and to call correct callback.
2113 Added silc_server_command_pending_check function to replace the
2114 corresnponding macro. The silc_command_pending list is not
2117 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2118 to set identifier to previously allocated Command Payload. It
2119 is used to set identifier for command when resending Command
2122 * Added silc_command_payload_encode_payload to encode Command
2123 Payload buffer from SilcCommandPayload structure.
2125 * Added silc_argument_payload_encode_payload to encode Argument
2126 payload buffer from SilcArgumentPayload structure.
2128 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Changed WHOIS command to support router connection on server side.
2131 The whois request is always sent to router unless the server is
2132 standalone server. After server has received the reply from the
2133 router will it send the reply to the client.
2135 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2136 broadcast received broadcast packet. The function is used only
2137 by router. The broadcast packet is always sent to the router's
2140 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2141 render given ID to printable string, for log files for example.
2143 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Made basic router to router connections working. At least they
2146 can now connect to each other but nothing really works the way
2147 they are supposed - yet.
2149 * Added new initiator token to RouterConnection configuration
2150 file in silcd/serverconfig.[ch]. It is used to tell whether we
2151 are the initiator to the remote router or whether we'll expect
2152 the other end to connect.
2154 * Moved registering of listener task to silc_server_init, hence
2155 the server starts listenning as soon as it is run, even if it
2156 does not have connections to other routers. Let's see how well
2159 * Changed default connection retry timeouts for more suitable in
2162 * Removed cipher and such arguments from silc_idlist_add_client
2163 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2164 Added new function silc_idlist_add_data to add the keys and stuff
2167 * Added SilcIDListData structure and added it to SilcClientEntry
2168 and SilcServerEntry as their first field in the structure. This
2169 way we can explicitly cast the ID entries to the SilcIDListData
2170 structure and get common data for the entries. In past, we had
2171 to first check what type of connection it is and then cast it to
2172 correct ID entry type. Now, we can directly cast the opaque
2173 pointer to the SilcIDListData (no matter what ID entry it actually
2174 is) and get the data needed.
2176 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2179 in some circumstances even if threre were timeout tasks, though not
2180 IO tasks, but tasks anyway. Now fixed.
2182 * Defined SilcServerConnection structure to hold connection specific
2183 stuff about directly connected servers and routers. The definition
2184 is currently in silcd/server_internal.h. I thought about having
2185 a bit more important role fro this struct but for now it is used
2186 only when connecting to other server (or router actually).
2188 * Added connecting retry support in server when connecting to
2189 router(s). The retry feature implement exponential backoff
2190 algorithm. Also, added SilcServerParams structure to hold default
2191 parameters for server. For now, it include these retry settings
2192 and are hard coded. After server is moded to be as Silc Server
2193 Library this structure will be more important.
2195 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Changed client librarys channel->clients table to SilcList and
2198 changed code accordingly.
2200 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Changed client's channel table to SilcList and changed code
2203 accordingly. Also changed SilcChannelClientEntry to include back-
2204 pointer to the channel so that client entry can use that structure
2205 as list as well and we have fast cross-reference to the channel.
2206 This change dramatically decreased the complexity of channel
2207 handling with client entry and vice versa (removed one extra
2208 loop when searching for channel entry from many functions).
2210 * Changed server->sim from table to SilcDList and changed code
2213 * NAMES command can now be used from user interface. It will show
2214 the user list on the channel, neatly.
2216 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2217 Code now saves realname of the user if it becomes available.
2219 * Renamed configure.in to configure.in.pre and made ./prepare
2220 script to automatically add correct version string to
2221 configure.in which it creates from configure.in.pre.
2223 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * NAMES command reply now shows users mode with the nickname when
2228 * Moved silc_client_ch[u]mode[_char] functions from
2229 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2230 place sucks, they are utility functions and should be in some
2233 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2235 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2238 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Added TRQ (efficient deque and list library) into lib/trq. This is
2243 a very good list library that is currently used in the SILC. Defined
2244 SilcList API over the library because I didn't like the API very
2245 much. See lib/trq/silclist.h for the API and examples of how to
2246 use the API. Fixed various places in the code to use the new
2247 SilcList API. The SilcList is meant for lists that has a structure
2248 already defined as a list. It is not suitable to add just some
2249 context to the list (in TRQ, the context is the list actually).
2251 So, I defined SilcDList that can be used for the purpose where
2252 predefined list structure does not exit. This can be used as
2253 such list. Now some context just can be added to the SilcDList.
2254 Currently this list is not used in the SILC just yet, though there
2255 are a lot places where this can replace dynamically allocated
2256 tables and I will fix these places, later, to use SilcDList.
2257 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2258 and use TRQ internally).
2260 Also fixed some annoying warning messages that the original TRQ
2261 code generated. Also minor changes to TRQ's Makefile.in.
2263 * Added support for querying by Client ID to both WHOIS and
2264 IDENTIFY commands into server, as required by the protocol.
2266 * Removed method function pointers from SilcBuffer structure. They
2267 weren't used to anything and just increased the context size for
2268 no good reason. This change also made silc_buffer_alloc and
2269 silc_buffer_free functions inline functions.
2271 * Disabled command flooding detection support until it's fixed so
2272 that it accepts commands in but does not execute them more than once
2275 * Added silc_net_localhost(), to return local hostname, into
2276 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2277 that must be initialized before calling silc_client_init.
2279 * Added new function: silc_server_send_notify_on_channels to send
2280 notify messages to all channels client has joined. It is assured
2281 that the message is sent only once per client.
2283 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2284 lib/silcutil/silcutil.[ch] as silc_format function. The new
2285 function is generic and is used by server as well, not only by
2286 the logging routines.
2288 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2289 the provided version string was not acceptable. Added new function:
2290 silc_ske_check_version into lib/silcske/silcske.h. The function
2291 must be implemented by the application (client or server) and it
2292 does not reside in the SKE library. The function checks the version
2293 string remote end sent.
2295 * Added back pointers (to opaque context and to SilcSocketConnection)
2296 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2298 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2299 duplicate packet context structure.
2301 * Changed `notify' client operation to send same arguments as client
2302 receives from server except for ID's. ID's are mapped to correct
2303 ID entry and that is returned. Also, if channel entry is not sent
2304 by server but the notify is for channel the channel entry is sent
2305 to application (otherwise application doesn't know that it is for
2306 channel (library gets it from packet's Destination ID)).
2308 * Added silc_client_remove_from_channels into client library to
2309 remove a client from all channels it has joined to. Used when
2310 received SIGNOFF notify from server. Added also new function
2311 silc_client_replace_from_channels to replace old ID entry with
2312 new ID entry on all channels. Used when received NICK_CHANGE
2315 * Fixed ID Cache list handling in silc_idlist_get_client in
2316 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2317 to get (or query) client by ID.
2319 * Updated TODO list.
2321 * Added connection authentication status message defined by the
2322 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2323 support for these into the code in client and server side.
2325 * Added generic function silc_client_send_command to send any command
2326 with variable argument list. Application should use this function
2327 to send commands if the command functions provided by the library
2328 does not suite for the application's user interface needs.
2330 * Added new `failure' client operation. Application is notified about
2331 received failure packet if client is executing a protocol. In this
2332 case the protocol's execution has failed.
2334 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2335 is required by the protocol.
2337 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2338 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2341 * Added status flag to SilcSKE object to indicate realtime status
2342 of the SKE protocol.
2344 * Application receives now exactly same command reply arguments as
2345 the library receives from server. However, if ID is received the
2346 corresponding ID entry is returned to the application (eg. Client
2347 ID is mapped to correct SilcClientEntry entry and that is returned).
2348 Changed command_reply client operation due to this change.
2350 * Changed all ID's in commands and in command replys as ID Payloads.
2351 Change affected both client and server side codes.
2353 All ID's sent in SILC network (with execption of ID's in SILC
2354 Packet header) are sent in ID Payload to support variable length
2357 * Server now notifies nick changes and notifies all clients on
2358 the channels about the new nickname (about the new Client ID,
2361 * Implemented CMODE command to change channel modes. Supports all
2362 channel modes defined by the protocol specs except ban and invite
2363 lists. (Also, private channel key mode is supported but support for
2364 setting private channel key in client is missing, thus, this mode
2365 has no effect on client side (except that server requires that the
2366 client uses private channel key and normal channel traffic does not
2369 Also, invite mode works per se, but INVITE command does not work
2370 yet correctly, so you can set channel as invite only channel but
2371 inviting clients to the channel does not work (it is yet to be
2372 thought what's the best way to do it).
2374 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2375 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2376 Implemented CUMODE command to change user's mode on the channel.
2377 Supports all modes defined by the protocol specs.
2379 * Added NAMES command reply to return users modes on the channel.
2381 * Removed unnecessary and slow ciphers from lib/silccrypt.
2383 * Set SO_KEEPALIVE option to connection sockets by default.
2385 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2387 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2388 redefined the Notify Payload into protocol specs.
2390 * Added silc_id_payload_parse_id to get ID directly from raw
2393 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2396 accept searching by Client ID as well.
2398 * Added support for LEAVE and SIGNOFF notify types in client library.
2400 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2401 to parse ID Payload from raw data.
2403 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Added flags parameter into silc_ske_assemble_security_properties
2406 function in lib/silcske/silcske.[ch].
2408 * Changed notify client operation to fit better for notify messages
2409 sent by server. The notify payload received from server is now
2410 passed to the application (after parsing it to SilcNotifyPayload).
2411 It is application's responsibility to retrieve the arguments
2412 from the payload and show the message the way it wants. The message
2413 sent by server is implementation specific.
2415 * Changed public keys to comply with the protocol specification.
2416 Old public keys are not supported anymore and are not compatible.
2418 * Removed nickname from Channel Payload as the latest draft removed
2419 it. The client must resolve the nickname from the NAMES command
2420 reply received when it joined the channel.
2422 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2424 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Fixed some errors in protocol specification drafts.
2428 * Created lib/silccore/silcnotify.c to implement Notify Payload
2429 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2430 generic payloads described by protocol specifications. The file
2431 includes implementations for ID Payload and Argument Payload.
2433 * Changed Command Payload implementation to use the new Argument
2434 Payload. Changed command_xxxx_payload to command_payload_xxxx
2435 to comply with SILC coding conventions.
2437 * Added suppport for Argument Payload handling in Notify Payload
2438 implementation as protocol requires it. Added the new support
2439 into server and client lib as well.
2441 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Added support for multiple nicknames on same channel. [n] is
2444 added locally to the nickname if there are more than one same
2445 nicknames on the channel.
2447 * Server now sends all nicknames that matched WHOIS request.
2448 Client also shows the list received from server.
2450 * Added TOPIC command to client side. User can now set and show
2451 current topic on channel.
2453 * Added MOTD command to client and server. Also, server sends the
2454 motd when client connects to the server.
2456 * Changed version strings to comply ISO 8601.
2458 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Fixed protocol error handling in client library. It should now
2461 cope even if the SKE fails for some reason.
2463 * Made new protocol specification drafts for submitting to IETF.
2465 * Implemented TOPIC command to server in silcd/command.c.
2467 * Added two new notify types into lib/silccore/silcnotify.h:
2468 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2469 notify nickname change and topic setting/change on a channel.
2471 * API change of command_reply operation in client library. The
2472 application gets now the status type received from server as well.
2474 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2478 * Cras fixed and optimized the packet handling even further and
2479 it should work now. Minor change to the prototype of function
2480 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2482 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Added new function into lib/silcutil/silcschedule.[ch]:
2485 silc_schedule_with_fd to select() a specified fd. The function
2486 returns after timeout expires or data arrives or goes. The
2487 function is used by packet routines to wait that all data is
2488 received from network.
2490 * Fixed data reading from network in lib/silccore/silcpacket.c.
2491 The code now assures that all data is read from the fd and then
2492 continues packet processing. This was a bug fix since the code
2493 used to drop some data in some circumstances.
2495 * Added new function into lib/silcclient/client.[ch]:
2496 silc_client_start_key_exchange to start key exchange after
2497 connection has been established to server. The code internally
2498 now uses this funtion but its main purpose was to provide it
2499 for applications that perform their own connecting. After
2500 application has created a connection it merely calls this
2501 function to start the key exchange between client and server.
2502 The library takes care of everything else after that.
2504 Updated also lib/silcclient/README to explain the usage of
2507 * Do not send to application information that connection has
2508 been established. Application gets notified it by connect
2511 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Applied cras's patch to add silc_schedule_one function. The
2514 function runs scheduler once and returns.
2516 * Fixed the scheduler after cras messed it up. The timeout
2517 handling works now as it's supposed to work.
2519 * Added into lib/silccore/ silcnotify.h to include notify
2520 message types support. Changed silc_server_send_notify*
2521 functions, in server.[ch], to support those new notify types.
2522 Added the support for the notify types into client library,
2523 as well. Added new notify client operation into ops.h in
2526 * Changed silc_server_packet_send_to_channel to send normal
2527 packets instead of just channel message packets. The function
2528 is now used to send the notify packets to channels. It is not
2529 used to send channel message packets anymore, as server never
2532 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2533 va_arg()s as it seems to require it nowadays. I guess, if SILC
2534 is compiled with older va_arg() the new code should work anyway.
2536 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Splitted core library. Core library (lib/silccore) includes
2539 now only SILC protocol specific core (and common) components.
2540 Created new utility library (lib/silcutil) that includes more
2541 generic purpose stuff. The stuff for util library was taken
2542 from the old core library. This was minor and easy split.
2544 * Created SILC Client Library (lib/silcclient) that includes
2545 implementation of the SILC client without user interface. This
2546 was major move from silc/ directory. The code has been changed
2547 so that it is transparent towards the user interface. The
2548 silc/ directory includes now the same user interface as before
2549 and it uses the new client library. Read lib/silcclient/README.
2550 Basicly, the client library performs everything else related
2551 to SILC except user interface handling. Also, configuration
2552 files are considered to be part of user interface and library
2553 does not handle them.
2555 This change also changed a lot of structures, function naming etc.
2556 Most important change was that SilcClientWindow object was
2557 renamed to SilcClientConnection in the client library. Created
2558 also new file lib/silcclient/ops.h. Also added new files
2559 silc/local_command.[ch] and silc/client_ops.[ch].
2561 All these changes were made to make it easier for user interface
2562 designers to create what ever user interface for the SILC client
2565 It is also expected that the server will be moved to lib
2566 directory as well and SILC Server Library will be created;
2567 sometimes in the future.
2569 * Removed Local commands from lib/silccore/silccommand.h as
2570 they are application specific and new client library does not
2571 handle any of those anymore.
2573 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2574 old client implementation in silc/.
2576 * Added support for callback functions in SILC_LOG_* macros.
2577 Application can now set its own callbacks that will be called
2578 instead of using the default functions that will always print
2579 the debug messages to stderr (or stdout). Also, debugging can
2580 now be disabled by setting silc_debug to FALSE and re-enabled by
2581 setting it to TRUE. Note, that logging will still work even
2582 if debugging is disabled.
2584 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2585 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2586 silc_log_reset_debug_callbacks.
2588 * To enable debugging in silc client one must give now -d
2589 option on command line.
2591 * Changed silc_schedule_init to automatically allocate task queues
2592 if they are not allocated before calling it.
2594 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Added GMP 3.1 into math library.
2598 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2600 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2601 a channel in SILC network. The packet is used by servers and
2602 routers to notify other routers that user has left a channel.
2603 This little feature was missing until now. Added the feature
2604 to protocol specification as well.
2606 Added functions: silc_server_send_remove_channel_user and
2607 silc_server_remove_channel_user into server.[ch].
2609 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2610 lib/silccore/silcpacket.h. However, they are not implemented
2613 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Fixed joining to a channel and sending channel messages
2616 between server and router. The channel message sending should
2617 now work inside a cell.
2619 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Fixed the private message sending between server and router.
2622 The private message sending should now work inside a cell.
2624 * Added silc_server_replace_id into server.[ch] to replace
2625 existing ID in the SILC network.
2627 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2628 and silc_idlist_replace_server_id into idlist.[ch] in server.
2630 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Fixed the server to server connections. Server can again now
2633 connect to router. Router to router connections probably does
2636 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Added dynamic protocol registering support. Now protocols can
2639 registered and unregistered on the fly. Patch by cras.
2641 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Added lib/contrib directory to hold routines that some platforms
2644 don't have but are needed by SILC.
2646 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2647 into lin/contrib to provide getopt() and getopt_long() for
2648 those who don't have it.
2650 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added AWAY command to client. When away message is set and
2653 client receives a private message packet the client automatically
2654 replies to the sender with the away message.
2656 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2657 bug seemed to be the cause of recent problems when compiling
2660 * Added version detection support to SKE protocol specification
2661 and added the new changes to the SKE implementation as well.
2662 There were other minor changes in the SKE protocol as well.
2664 Many changes in lib/silcske/silcske.[ch] and in
2665 lib/silcske/payload.[ch].
2667 * Added ^U functionality, clear input line. Patch from cras.
2669 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Mainly small bugfixes on core library. Fixed some debugging
2672 logging and buffer overflow in silclog.c.
2674 * Updated config.sub and config.guess on the distribution tree.
2676 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Added command lagging support in server. Client may execute
2679 commands now only once in two seconds.
2681 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Optimized packet reception. MAC computation and checking is now
2684 also more optimized. A lot previously duplicated code is now
2685 used as generic by both client and server.
2687 * Fixed key pair generation in clientutil.c
2689 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added into lib/silccore/silcbufutil.[ch] new function;
2692 silc_buffer_realloc.
2694 * Moved generic packet sending/encryption functions to
2695 lib/silccore/silcpacket.[ch] from client and server. Some
2696 rewriting of the functions.
2698 * Moved all generic packet reception/decryption functions to
2699 lib/silccore/silcpacket.[ch] from client and server. The
2700 packet processing is now much cleaner in both client and server.
2701 These were major changes in both client and server.
2703 * Created many common functions in server to do packet sending.
2704 Previously code were duplicated a lot, this has been removed
2707 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Rewrote major parts of the ID cache system. Don't know
2710 whether it is better now or not but at least the API is more
2713 * Major rewrite on ID cache stuff on client because of the ID
2714 cache API changes. Added idlist.c to client.
2716 * Also major rewrite on ID cache stuff on server as well.
2717 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2718 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2719 in hand, instead they are all put into the ID cache system now.
2720 All server_idlist_* routines uses ID cache now instead of
2721 traversing its own lists (those lists does not exist anymore).
2722 SilcIDList though still exists. Also, SilcXXXEntry's are
2725 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Finally made the SKE implementation compliant to the protocol
2728 specification. All mp integers are now binary encoded as
2729 opposed being HEX encoded.
2731 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2734 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2735 functions: silc_[encode/decode]_pem. Also added function
2736 silc_encode_pem_file to PEM encode with newlines ('\n') for
2739 * SILC public keys are now encoded either PEM or binary. Same
2740 option is for private keys as well. By default private keys
2741 are binary encoded and public keys PEM encoded. Silly HEX
2742 encoding were removed.
2744 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2745 function to create fingerprints.
2747 * Fixed a bug in SHA1; does not change the original data anymore.
2749 * Partly implemented INFO command on client and server side.
2750 Fixed CLEAR command. Changes to SERVER command; show current
2751 server(s) when giving command without arguments. Added
2752 VERSION command to client.
2754 * Added check to server that unregistered connections cannot
2755 execute commands (unless it is specificly allowed).
2757 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Fixed screen refresh.
2761 * Fixed channel joining bug from client. On some circumstances
2762 client tried to join to a channel it had already joined.
2764 * Added public key verification process into client's protocol.c.
2765 The client now verifies the public key from user and saves
2766 it into ~./silc/serverkeys/ directory.
2768 Added into: clientutil.[ch]: silc_client_verify_server_key.
2770 * Changed SKE protocol's silc_ske_initiator_finish function
2771 to accept callback function that verifies the received public
2772 key. Removed old silc_ske_verify_public_key function.
2774 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2777 silc_pkcs_private_key[_data]_set.
2779 * Made the password and public authentication more cleaner in
2780 server's protocol.c.
2782 * Removed historic and obsolete protocol `channel_auth' from
2783 both client and server.
2785 * Removed wrong way of sending command status messages from
2786 server to client in server's command.c. The old way violated
2787 protocol specification.
2789 Changes to silccore/silccommand.[ch]: removed
2790 silc_command_encode_status_payload -> not needed anymore,
2791 changed silc_command_encode_payload_va to accept extra
2792 argument on variable argument list. The argument type must
2793 now be provided to the function. Also, added new function:
2794 silc_command_encode_reply_payload_va which is same as
2795 normal command_encode_payload_va except command status type
2796 is provided as extra argument.
2798 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added ~./silc directory handling. The directory includes the
