1 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added silc_server_connection_auth_request to handle the
4 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5 silcd/packet_receive.[ch].
7 * Added silc_server_send_connection_auth_request into the
8 silcd/packet_send.c to send the connection auth request packet.
10 * Cleaned up the silcd/protocol.c a bit and fixed some memory
13 * Fixed the public key authentication in responder side in the
14 server. The `auth_data' pointer includes the SilcPublicKey
15 not the path to the public key. Affected file silcd/protocol.c.
17 * Implemented the public key authentication in the initiator side
18 in the server. Affected file silcd/protocol.c.
20 * Removed the [RedirectClient] config section from the server
21 configuration. Is not needed and I don't want to implement it.
23 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Cleaned up the CMODE command in the server. It now works
26 correctly and supports all the modes defined in the protocol.
27 Affected file is silcd/command.c.
29 * Added `hmac_name' field to the SilcChannelEntry in the server
30 to hold the default HMAC of the channel. It can be set when
31 creating the channel (with JOIN command). Affected files
34 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
35 type to indicate the change of the current cipher and hmac
36 on the channel. Client can safely ignore the <cipher> argument
37 (if it chooses to do so) since the CHANNEL_KEY packet will
38 force the channel key change anyway. The <hmac> argument is
39 important since the client is responsible of setting the new
40 HMAC and the hmac key into use.
42 * Fixed the CMODE command in the client library as well.
44 * Tested CMODE command in router environment successfully.
46 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Show the version of the remote client (or server) when connecting
49 to the server. It is logged to the log file. Affected file
52 * Fixed the KILLED notify handling in the client library. The
53 client must be removed from all channels when receiving the
56 Also, do not remove the client entry when giving the KILL
57 command but when the KILLED notify is received.
59 * Removed silc_idlist_find_client_by_nickname from the server.
60 Not needed anymore. Affected files silcd/idlist.[ch].
62 * Implemented the CHANNEL_CHANGE notify type handling to the
63 server. Affected file silcd/server.c.
67 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added silc_server_send_notify_invite to send the INVITE
70 notify between routers.
72 * Implemented the INVITE command correctly to the server.
74 * Implemented the INVITE notify type handling in the server.
76 * Implemented the INVITE command to the client library and on the
79 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added function silc_server_get_client_resolve to find the
82 client entry by ID from all ID lists and then resolve it
83 (using WHOIS) if it cannot be found. Affected file is
86 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * Implemented the BAN command to the client library.
90 * The JOIN command in the server now checks the invite list
93 * Changed the silc_command_reply_payload_encode_va and the
94 silc_command_payload_encode_va to support that if argument is
95 NULL it ignores and checks the next argument. Affected file
96 lib/silccore/silccommand.c.
98 * Added silc_server_send_notify_ban to send the BAN notify
101 * Chaned the silc_notify_payload_encode to support that if
102 argument is NULL it ignores and checks the next argument.
103 Affected file lib/silccore/silcnotify.c.
105 * Tested ban lists in router environment successfully.
107 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Implemented BAN command to the server, in silcd/command.[ch].
111 * Removed the BAN and INVITE_LIST modes from the CMODE command
114 * Added function silc_string_match to regex match two strings.
115 Affected files lib/silcutil/silcutil.[ch].
117 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Redefined parts of the SilcChannelEntry in the server to support
120 the new ban and invite lists.
122 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Redefined the INVITE command. The same command can be used to
125 invite individuals to the channel but also to manage the invite
126 list of the channel (to add to and remove from the invite list).
127 Updated the protocol specs.
129 * Added new command SILC_COMMAND_BAN that can be used to manage
130 the ban list of the channel. Updated the protocol specs.
132 * Removed the channel modes: the SILC_CMODE_BAN and the
133 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
134 in the CMODE command. The equivalent features are now available
135 using INVITE and BAN commands. Updated the protocol specs.
137 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
138 in the network about change in the current ban list. The notify
139 type is not used by the client.
141 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
142 support the invite lists.
144 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Added new function silc_string_regexify that converts string
147 including wildcard characters into regex string that can
148 be used by the GNU regex library. Added into the file
149 lib/silcutil/silcutil.[ch].
151 Added silc_string_regex_combine to combine to regex strings
152 into one so that they can be used as one regex string by
153 the GNU regex library. Added into the file
154 lib/silcutil/silcutil.[ch].
156 Added silc_string_regex_match to match two strings. It returns
157 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
159 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Imported GNU regex to the soruce tree into lib/contrib.
162 Fixed some compiler warning from the regex.c.
164 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Fixed MOTD command in the server to work in router environment.
168 * Fixed the MOTD command in the client library to support
169 the server argument in the command.
171 * Added `nickname_len' argument to the silc_idlist_add_client
172 in the server, as the `nickname' argument may be binary data
175 * Added silc_idlist_get_channels to return all channels from
178 * Implemented LIST command to the server. Affected file is
181 * Implemented the LIST command to the client library and on the
184 * Added [<user count>] argument to the LIST command reply.
185 With private channels the user count is not shown.
187 * Updated TODO and README.
189 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * The client entry's data.registered must be TRUE even with
192 global client entry on global client list. The data.registered
193 is used to check whether the client is anymore in the network,
194 for example with WHOWAS command so it must be valid.
196 * Fixed the WHOWAS command in the server. It now actually works
197 in router environment. Added function into silcd/command_reply.c
198 silc_server_command_reply_whowas_save.
200 * Added silc_idlist_purge function to the silcd/idlist.c
201 to periodically purge the ID Cache.
203 * Fixed INFO command in the server. It works now in router
204 environment. Added <server name> argument to the INFO command
205 reply. Updated the protocol specs.
207 * Fixed minor bug in silc_idcache_purge to not purge if the
208 expire value is zero.
210 * Fixed various bugs in WHOIS and IDENTIFY command handling as
211 they were buggy because of the WHOWAS information.
213 * Fixed local command MSG to handle the async resolving of
214 the remote client properly. It used to fail the first MSG.
215 Affected file silc/local_command.c.
217 * Added `data_len' field to SilcIDCache context.
219 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Update TODO. Todo in commands in the server.
223 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
226 used by routers as broadcast packet to inform other routers
227 about the changed user mode.
229 Implemented the notify handling in the server. Affected file is
230 silcd/packet_receive.c. Added the function
231 silc_server_send_notify_umode to the silcd/packet_send.[ch].
233 * Added new generic Channel Payload and deprecated the New Channel
234 Payload. The New Channel Payload is now the generic Channel
237 * Added new argument `mode' to the silc_server_send_new_channel
238 as it is required in the Channel Payload now.
240 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
241 and created a new and real SilChannelPayload to represent the
242 new generic Channel Payload. Implemented the encode/decode
243 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
245 * Added silc_server_get_client_channel_list to return the list
246 of channels the client has joined for WHOIS command reply.
247 Affected file silcd/server.[ch].
249 * Implemented the channel list sending in the WHOIS command reply
250 in server and in the client.
252 Implemented the channel list displaying on the user interface
253 as well. Affected file silc/client_ops.c.
255 * Added silc_channel_payload_parse_list to parse list of Channel
256 Payloads. It returns SilcDList list of SilcChannelPayloads.
257 Client for example can use this function to parse the list of
258 channels it receives in the WHOIS command reply. The caller
259 must free the list by calling silc_channel_payload_list_free.
260 Affected files lib/silccore/silcchannel.[ch].
262 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Added one new argument <user mode> to the WHOIS command reply
265 to return the mode of the user in SILC. Updated the protocol
268 Implemented it to the server and client.
270 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Fixed the mode printing on the user interface on joining.
273 Affected file silc/client_ops.c.
275 * Implemented the UMODE command and user modes in general to the
276 client library and to the user interface.
278 * Implemented the UMODE command to the server.
280 * The server now sends UNKNOWN_COMMAND error status if client sends
281 unknown command. Affected file silcd/command.c.
283 * All server commands now handle the command identifier the right
284 way when sending the command reply to the client. The client can
285 use to identify the command replies with the identifier.
287 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Added silc_server_get_client_route to resolve the route to
290 the client indicated by the client ID. Affected file is
293 * Added silc_server_relay_packet as general function to relay
294 packet to arbitrary destination. This deprecates functions
295 like _send_private_message_key, _relay_notify etc. Affected
296 file is silcd/packet_send.[ch].
298 Removed silc_server_send_key_agreement,
299 silc_server_send_private_message_key and
300 silc_server_packet_relay_notify functions from the file
301 silcd/packet_send.[ch].
305 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
306 server. Affected file silcd/packet_receive.[ch].
308 * Implemented the KILL command to the client. Implemented the
309 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
310 Affected files lib/silcclient/command[_reply].c and
311 lib/silcclient/client_notify.c. Implemented the KILL notify
312 printing in the user inteface.
314 * Fixed a lot silc_parse_nick memory leaks from the client
315 library in the file lib/silcclient/command.c.
317 * Changed the silc_server_send_notify_on_channels's `sender'
318 argument from SilcSocketConnection to SilcClientEntry to
319 check the sender as entry and not as connection object and not
320 to send to the client provided as argument. The affected file
321 is silcd/packet_send.[ch].
323 * The notify packets that are destined directly to the client used
324 to not to be processed by the server. Now changed that and the
325 server processes all notify packets. After relaying the packet
326 to the client the notify packet is processed in the server.
328 * The silc_server_free_client_data now checks whether there is
329 pending outgoing traffic for the client and purges the data to
330 the network before removing the client entry.
332 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
335 an client is killed from the SILC Network. Updated the protocol
338 Added new function silc_server_send_notify_killed to the
339 silcd/packet_send.[ch].
341 * Added function silc_server_packet_relay_notify to relay notify
342 packets that are destined directly to a client. In this case
343 the server does not process the notify packets but merely relays
344 it to the client. Affected file silcd/packet_send.[ch].
346 Added also silc_server_packet_process_relay_notify to check
347 whereto relay the notify. Affected file is
348 silcd/packet_receive.[ch].
350 * Implemented the KILL command to the server.
354 * Added the backup schema desgined last fall to the protocol
355 specs for everyone to see. The specification is in the
356 *-spec-xx.txt draft and the packet type definitions for the
357 backup routers is in *-pp-xx.txt draft. Thusly, added also
358 new packet type SILC_PACKET_CELL_ROUTERS.
360 * A big security problem in the implementation discovered. The
361 signoff of an client did not cause new channel key generation
362 which it of course should've done. The channel keys must be
363 always re-generated when client leaves (or signoffs) the channel.
364 The silc_server_remove_from_channels funtion now handles
365 the channel key re-generation.
367 * Added `sender' argument to the silc_server_send_notify_on_channels
368 to not to send the client provided as argument. Affected file
369 silcd/packet_send.[ch].
371 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
373 * Implemented OPER and SILCOPER commands into the server and
376 * Added silc_auth_verify and silc_auth_verify_data to verify
377 the authentication directly from the authentication payload.
378 It supports verifying both passphrase and public key based
379 authentication. Affected file lib/silccore/silcauth.[ch].
381 * Added `hash' field to the SilcIDListData structure. It is the
382 hash negotiated in the SKE protocol. Affected file is
385 * Slight redesigning of the SilcAuthPayload handling routines.
386 Do not send SilcPKCS but SilcPublicKey as argument.
388 * Implemented the public key authentication support to the
389 serverconfig. The public key is loaded from the provided path
390 and saved as authentication data to void * pointer. Thus,
391 changed the unsigned char *auth_data to void *auth_data;
393 * Fixed SHUTDOWN command to send the reply before the server
394 is shutdown. :) Affected file silcd/command.c.
396 * Fixed fatal bug in CONNECT command. The hostname was invalid
397 memory and server crashed. Affected file silcd/command.c.
399 * Fixed fatal bug in CLOSE command. The server_entry became
400 invalid but was referenced later in the command. Affected file
403 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Fixed fatal bug in failure packet handling. Server ignored
406 the failure and thus crashed when it came.
410 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
413 that the command may be executed only once in (about) 2 seconds.
414 The old SILC_CF_LAG flag is same but allows command bursts up
415 to five before limiting.
417 Added the support for CF_LAG and CF_LAG_STRICT flags to the
418 server code. Various commands now includes the CF_LAG_STRICT
419 flag to disallow any kind of miss-use of the command.
421 * Fixed the silc_buffer_unformat to not to allocate any data
422 if the length of the data is zero. It used to allocate the
423 length + 1. Affected file lib/silcutil/silcbuffmt.c.
425 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Changed the format of AdminConnection configuration section
428 in the server. Added username of the admin to the format.
429 Affected files silcd/serverconfig.[ch].
431 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
432 to return admin configuration data by host, username and/or
435 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Implemented WHOWAS command to the server. Added the functions:
439 silc_server_command_whowas_parse,
440 silc_server_command_whowas_send_reply,
441 silc_server_command_whowas_from_client and
442 silc_server_command_whowas_from_server
444 * Added <Client ID> argument to the WHOWAS command reply. Updated
445 the protocol specs accordingly.
447 * Implemented WHOWAS command and command_reply to the client
450 Implemented the WHOWAS printing on the user interface.
452 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Added new argument to the WHOWAS command reply, the real name.
455 It is an optional argument. Updated the protocol specs.
457 * Added SilcIDCacheDestructor callback that is registered when
458 the SilcIDCache is allocated. The callback is called when
459 an cache entry in the ID Cache expires, or is purged from the
460 cache. Added into lib/silccore/idcache.[ch].
462 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
463 to destruct the client entries when the cache entry expires.
464 Other ID Cache's in server and in the client library ignores
467 * If the ID Cache entry's `expire' field is zero then the entry
468 never expires. Added boolean `expire' argument to the
469 silc_idcache_add function in the lib/silccore/idcache.[ch].
470 If it is TRUE the default expiry value is used.
472 * Added silc_server_free_client_data_timeout that is registered
473 when client disconnects. By default for 5 minutes we preserve
474 the client entry for history - for WHOWAS command.
476 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Added support to the server to enforce that commands are not
479 executed more than once in 2 seconds. If server receives
480 commands from client more frequently, timeout is registered
481 to process the commands. Affected file silcd/command.c.
482 Added new function silc_server_command_process_timeout.
484 * Changed NICK_NOTIFY handling in client library to check that
485 if the client's nickname was changed, so there is no need to
486 resolve anything from the server.
488 * Removed error printing from the WHOIS and IDENTIFY commands.
489 If error occurs then it is ignored silently in the client library.
490 The application, however, may map the received error to
491 human readable error string. The application currently maps
492 the NO_SUCH_NICKNAME error to string.
494 * Made the command status message public to the application. Moved
495 them from lib/silcclient/command_reply.c to
496 lib/silcclient/command_reply.h. The application can map the
497 received command status to the string with the
498 silc_client_command_status_message function.
500 * Added check to the server to check that client's ID is same
501 as the Source ID in the packet the client sent. They must
504 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Added dist-bzip hook to the Makefile.am to make bzip2
507 compressed distributions.
509 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Server now enforces the maximum length for the nickname and
512 the channel as protocol specification dictates. 128 bytes for
513 nickname and 256 bytes for channel name.
515 * Moved the WHOIS printing to the application. The client libary
516 does not print out the WHOIS information anymore, the application
517 must do it. Renamed silc_client_command_reply_whois_print to
518 the silc_client_command_reply_whois_save.
520 The client's idle time is also sent to the application now, and
521 the idle is shown on screen.
523 * Added silc_client_command_reply_identify_save to save the
524 received IDENTIFY entries.
526 * Do not check for channel private keys in message sending and
527 reception if the channel does not have the PRIVKEY mode set.
528 Affected file lib/silclient/client_channel.c.
530 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
533 just surfaced after chaning the JOIN procedure.
535 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Added silc_client_get_clients_by_list to get client entries
538 from Client ID list, that is returned for example by JOIN
539 and USERS command replies. The application should use this
540 function for example when JOIN command reply is received to
541 resolve the clients already on the channel (library does not
542 do that anymore as USERS command reply is not used in the JOIN
543 procedure anymore). Affected files lib/silcclient/silcapi.h and
544 lib/silcclient/idlist.c.
546 * JOIN command reply and USERS command reply returns now SilcBuffer
547 pointers instead of unsigned char pointers when returning
548 the client list and mode list.
550 * Added <Client ID> argument to the JOIN command reply, mainly
551 for the server to identify for which client the command was
552 originally sent. Updated protocol specs accordingly.
554 * Added SilcDlist private_key pointer to the SilcChannelEntry
555 in the client to support the channel private keys. Affected
556 file is lib/silcclient/idlist.h.
558 * Added SilcChannelPrivateKey argument to the function
559 silc_client_send_channel_message so that application can choose
560 to use specific private ke if it wants to. If it is not provided,
561 the normal channel key is used, unless private keys are set.
562 In this case the first (key that was added first) is used
563 as the encryption key.
565 * Implemented the support for channel private key handling.
566 Implemented the following functions:
568 silc_client_add_channel_private_key,
569 silc_client_del_channel_private_keys,
570 silc_client_del_channel_private_key,
571 silc_client_list_channel_private_keys and
572 silc_client_free_channel_private_keys
574 Affected file lib/silcclient/client_channel.c.
576 * Added the support for the private keys in the channel message
577 sending and encryption and in the message reception and
578 decryption. Affected funtions are
579 silc_client_send_channel_message and silc_client_channel_message.
581 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added SKE's key verify callback to the client library's
584 KE protocol context. Affected files lib/silcclient/protocol.[ch].
586 * Removed the statement that server (or router) must send USERS
587 command reply when joining to the channel so that the client
588 knows who are on the channel. Instead, the client list and
589 client's mode list is now sent in the JOIN command reply to the
590 client who joined channel. This is better solution.
592 * Added function silc_server_get_users_on_channel and function
593 silc_server_save_users_on_channel to the silcd/server.[ch].
595 * Removed function silc_server_command_send_users from the
598 * Do not show topic on the client library anymore. The topic is
599 sent in the command reply notify to the application and the
600 application must show the topic now.
602 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Added client searching by nickname hash into the IDENTIFY and
605 WHOIS commands in the server as they were clearly missing from
606 them. Affected file is silcd/command.c.
608 * Fixed a bug in private message receiving in the client library.
609 The remote ID was freed and it wasn't supposed, now it is
612 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Minor fix to the channel payload; allocate the data area, as it
615 needs to be of specific length.
617 * If the key agreement port is zero then the operating
618 system will define the bound port. Affected files are
619 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
621 * Added new function silc_channel_payload_decrypt into the file
622 lib/silccore/silcchannel.[ch].
624 * Moved the channel message etc, check from silc_packet_decrypt
625 to applications. The library calls now a generic
626 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
627 when the packet is either normal or special. This was done to
628 allow more wide range of checking that was not allowed when
629 the code was in library. Now applications can do virtually any
630 checks to the packet and return to the library the decision how
631 the packet should be processed. Affected files are
632 lib/silccore/silcpacket.[ch].
634 Added silc_server_packet_decrypt_check to the server and
635 silc_client_packet_decrypt_check to the client library.
637 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
638 to send with specified source and destination information.
640 * Channel message delivery between routers was broken after the
641 channel key distribution was fixed earlier. The channel key
642 was used be to distributed to other routers as well which is not
643 allowed by the protocol. Now this is fixed and channel keys
644 really are cell specific and the channel message delivery between
645 routers comply with the protocol specification.
647 * Fixed various commands in server to check also the global list
648 for the channel entry and not just the local list. The affected
649 file silcd/command.c.
651 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * Added assert()s to buffer formatting and unformatting routines
654 to assert (if --enable-debug) when error occurs. Affected
655 file: lib/silcutil/silcbuffmt.c.
657 * Changed to auto-reconnect to check whether the remote host is
658 router and register the re-connect timeout if it is. It used
659 to check that whether we are normal server, but router must do
660 auto-reconnect with another router as well. Affected file
663 * Removed the [<key len>] option from CMODE command as the cipher
664 name decides the key length, nowadays. See the defined ciphers
665 from the protocol specification.
667 * Added [<hmac>] option to the CMODE command to define the HMAC
668 for the channel. Added SILC_CMODE_HMAC channel mode.
670 * Added [<hmac>] option for the JOIN command so that user can
671 select which HMAC is used to compute the MACs of the channel
674 * Added Hmac field to the Channel Message Payload. The integrity
675 of plaintext channel messages are now protected by computing
676 MAC of the message and attaching the MAC to the payload. The
677 MAC is encrypted. Now, it is clear that this causes some
678 overhead to the size of the packet but rationale for this is that
679 now the receiver can verify whether the channel message decrypted
680 correctly and also when private keys are set for the channel the
681 receiver can decrypt the packet with several keys and check from
682 the MAC which key decrypted the message correctly.
684 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
685 lib/silccrypt/silccipher.[ch].
687 * Added silc_hash_len to return the digest length into the
688 lib/silcrypt/silchash.[ch].
690 * Rewrote parts of Silc Channel Payload interface in the
691 lib/silccore/silcchannel.[ch]. The encode function now also
692 encrypts the packet and parse function decrypts it.
694 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Fixed a minor formatting bug in the SKE's key material processing.
697 It actually might have processed the keys wrong way resulting
700 * Redefined the mandatory HMAC algorithms and added new algorithms.
701 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
702 and hmac-md5 truncated to 96 bits. The mandatory is now
703 hmac-sha1-96. Rest are optional (including the one that used
704 to be mandatory). Rationale for this is that the truncated HMAC
705 length is sufficient from security point of view and can actually
706 make the attack against the HMAC harder. Also, the truncated
707 HMAC causes less overhead to the packets. See the RFC2104 for
710 * Added new [hmac] configuration section. The SKE used to use
711 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
712 is of course wrong. The official names that must be proposed in
713 the SKE are the ones defined in the protocol specification
714 (hmac-sha1-96 for example). The user can configure any hmac
715 using any hash function configured in the [hash] section. At
716 least, the mandatory must be configured.
718 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
720 * Added HMAC list to the SKE proposal list. It has now both
721 hash algorithm list and HMAC list. This makes the protocol
722 incompatible with previous versions. The SKE now seems to work
723 the way it is supposed to work, for the first time actually.
725 * Defined plain Hash algorithms to the protocol specification.
728 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Implemented support for key agreement packets into the server.
731 Added functions silc_server_key_agreement and
732 silc_server_send_key_agreement. Other than these functions,
733 server has nothing to do with this packet.
735 * Added support for private message key packets into the server.
736 Added functions silc_server_private_message_key and
737 silc_server_send_private_message_key.
741 * Changed the silc_[client|server]_protocol_ke_set_keys to be
742 called in the protocol's final callback instead in the END
743 protocol state. This makes a little more sense and in the same
744 time in client we can use the same protocol routines for normal
745 key exchange and to key agreement packet handling as well.
747 * Added to both client's and server's KE protocol context the
748 SilcSKEKeyMaterial pointer to save the key material. We will
749 bring the key material to the protocol's final callback by doing
750 this. The final callback must free the key material.
752 * Added SKE's packet_send callback into client's KE protocol
753 context so that the caller can choose what packet sending function
754 is used. This way we can use different packet sending when
755 doing normal SKE when doing key agreement packet handling (in
756 the key agreement packet handling we do not want to encrypt
759 * Implemented the responder side of the key agreement routines
760 in the client. The client can now bind to specified port and
761 accept incoming key negotiation. The key material is passed
762 to the application after the protocol is over.
764 * Implemented the processing of incoming Key Agreement packet
765 in the client. Added function silc_client_key_agreement to
768 * Implemented the intiator side of the key agreement routines
769 in the client. The client can now initiate key agreement with
770 another remote client. The key material is passed to the
771 application after the protocol is over.
773 * Created client_keyagr.c to include all the key agreement
776 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
777 SILC_TASK_CALLBACK except that it is not static.
779 * Created client_notify.c and moved the Notify packet handling
780 from the client.[ch] into that file.
782 * Created client_prvmsg.c and moved all private message and
783 private message key routines from the client.[ch] into that file.
785 * Create client_channel.c and moved all channel message and
786 channel private key routines from the client.[ch] into that file.
788 * Changed silc_client_get_client_by_id_resolve to resolve with
789 WHOIS command instead of IDENTIFY command, in the file
790 lib/silclient/idlist.c.
792 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
794 * Implemented the SKE's responder side to the Client library.
796 * When FAILURE is received to the protocol do not trust it
797 blindly. Register a timeout to wait whether the remote closes
798 the connection as it should do it, only after that process the
799 actual failure. This was changed to both client and server.
801 * Added client_internal.h to include some of the structures
802 there instead of client.h in lib/silcclient/.
804 * Added function silc_task_unregister_by_callback to unregister
805 timeouts by the callback function.
807 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Some "Incomplete WHOIS info" errors has been appearing on the
810 log files. Took away the entry->userinfo check from WHOIS
811 reply sending. The entry->userinfo is now " " if client did not
812 provide one. I thought this was fixed earlier but something
813 is wrong still. Let's see if the error still appears.
815 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Fixed a minor bug in the login when the channel key is
818 re-generated in the server. It used to generate the key in
819 wrong order and thus caused problems in the channel traffic.
821 * Fixed a minor bug in channel key distsribution after
822 KICK command. The key was not sent to the router even though
825 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added silc_ske_process_key_material_data as generic routine
828 to process any key material as the SILC protocol dictates. The
829 function is used by the actual SKE library but can be used by
830 applications as well. This relates to the private message keys
831 and the channel private keys since they must be processed the
832 same way the normal SILC session keys. The protocol dictates
833 this. Affected files: lib/silcske/silcske.[ch].
835 Added also silc_ske_free_key_material to free the
836 SilcSKEKeyMaterial structure.
838 * Defined silc_cipher_set_key function to set the key for
839 cipher without using the object's method function. The affected
840 files: lib/silccrypt/silccipher.[ch].
842 * Implemented silc silc_client_add_private_message_key,
843 silc_client_add_private_message_key_ske,
844 silc_client_del_private_message_key,
845 silc_client_list_private_message_keys and
846 silc_client_free_private_message_keys functions in the
849 Added functions silc_client_send_private_message_key to send
850 the Private Message Key payload and silc_client_private_message_key
851 to handle incoming Private Message Key payload.
853 * Added Cipher field to the Private Message Key payload to set
854 the cipher to be used. If ignored, the default cipher defined
855 in the SILC protocol (aes-256-cbc) is used.
857 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
859 * Removed lib/silcclient/ops.h file.
861 Redefined parts of the SILC Client Library API. Created new
862 file silcapi.h that deprecates the ops.h file and defines the
863 published Client Library API. Defined also private message key
864 API and channel private key API into the file.
866 This is the file that the application must include from the
867 SILC Client Library. Other files need not be included by
868 the application anymore.
870 * Added new key_agreement client operation callback and also
871 defined the Key Agreement library API for the application.
873 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
876 is used by clients to request key negotiation between another
877 client in the SILC network. If the negotiation is started it
878 is performed using the SKE protocol. The result of the
879 negotiation, the secret key material, can be used for example
880 as private message key.
882 Implemented the Key Agreement payload into the files
883 lib/silccore/silauth.[ch].
885 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Redefined ciphers for the SILC protocol. Added some new ciphers
888 and defined the key lengths for the algorithms. Changed the
889 code accordingly. The default key length is now 256 bits.
891 * Fixed SKE key distribution function silc_ske_process_key_material
892 when the key length is more than 128 bits. The default key
893 length in SILC is now 256 bits.
895 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
896 to indicate unsupported algorithm.
898 * Renamed rijndael.c to aes.c and all functions as well.
900 * Fixed a long standing channel key setting bug in client library.
901 Weird that it has never surfaced before.
903 * Fixed bug in channel deletion. If the entire channel is removed
904 then it must also delete the references of the channel entry
905 from the client's channel list as the client's channel entry and
906 the channel's client entry share same memory.
908 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Implemented CONNECT and SHUTDOWN commands in the client.
912 * Implemented CLOSE command to the client.
914 * Added the function silc_idlist_find_server_by_name into the
915 files silcd/idlist.[ch].
917 Added the function silc_idlist_find_server_by_conn into the
918 files silcd/idlist.[ch].
920 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * DIE command was renamed to SHUTDOWN. Updated the both code
925 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
926 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
928 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
931 * Added function silc_server_create_connection function to create
932 connection to remote router. My server implementation actually
933 does not allow router to connect to normal server (it expects
934 that normal server always initiates the connection to the router)
935 so the CONNECT command is only good for connecting to another
938 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
941 or some other client was kicked from the channel.
943 Implemented the handling of the notify type to both client
946 Implemented silc_server_send_notify_kicked to send the KICKED
947 notify. It is used to send it to the server's primary router.
949 * Implemented the KICK command into server and client.
951 * Added `query' argument to the silc_idlist_get_client function
952 to indicate whether to query the client from server or not if
955 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
956 to indicate that the client is not channel founder.
960 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Removed the rng context from SilcPacketContext structure and
963 changed that the packet routine uses the Global RNG API.
965 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Added support for quit message that client can "leave" on the
968 channel when it quits the SILC. It is ditributed inside the
969 SILC_NOTIFY_TYPE_SIGNOFF notify type.
971 Added silc_server_free_client_data that will take the
972 signoff message as argument.
974 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
976 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Updated parts of the protocol specification to keep it up
981 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
984 payloads in one packet.
986 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
987 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
988 use now the new List flag.
990 * Also deprecated the following packet types: REPLACE_ID,
991 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
993 * Added list support for Notify packet in server.
995 * Added silc_server_send_notify_channel_change to send the
996 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
997 the silc_server_send_replace_id.
999 * Added silc_server_send_notify_nick_change to send the
1000 NICK_CHANGE notify type. Deprecates the function
1001 silc_server_send_replace_id.
1003 * Added silc_server_send_notify_join to send the JOIN notify type.
1004 Deprecates the function silc_server_send_new_channel_user.
1006 * Added silc_server_send_notify_leave to send LEAVE notify type.
1007 Deprecates the function silc_server_send_remove_channel_user.
1009 * Added silc_server_send_notify_cmode and
1010 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1011 types. Deprecates the silc_server_send_set_mode function.
1013 * Added SERVER_SIGNOFF notify type to indicate that server has
1014 quit. This means that all clients on the channel from that
1015 server will drop. This can be also used when netsplit happens.
1017 Deprecated REMOVE_ID packet type since it is not needed anymore
1020 Added silc_server_send_notify_server_signoff to send the
1021 SERVER_SIGNOFF notify type. Deprecates the function
1022 silc_server_send_remove_id.
1024 Added also silc_server_send_notify_signoff to send the
1025 SIGNOFF notify type.
1027 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1028 SILC protocol from this day on. Changed the protocol
1029 specification as well.
1031 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1032 notify type. It is used between routers to notify about
1033 topic changes on a channel.
1035 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1038 * Partly updated the protocol specification to comply with the
1039 changes now made. It is still though a bit outdated.
1041 * The JOIN notify type now takes one extra argument <Channel ID>.
1042 The packet used to be destined to the channel but now the
1043 JOIN type may be sent as list thus it is impossible to
1044 destine it to any specific channel. By adding this argument
1045 it is again possible.
1047 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Added CREDITS file. The CHANGES and CREDITS file will appear
1050 in the distribution as well.
1052 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1055 types in the server's silcd/packet_receive.c.
1057 * Implemented CMODE and CUMODE to work in router environment.
1059 * Fixed minor encoding and decoding buglet from the
1060 lib/silccore/silcmode.c.
1062 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1065 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1067 * Changed all SilcConfigServer* and silc_config_server* to
1068 SilcServerConfig* and silc_server_config*, respectively.
1071 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Associated the ID (client or server ID) to the Authentication
1074 Payload to avoid any possibility of forging. Updated the
1075 protocol specification and the code accordingly.
1077 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * The RSA key length is now save to the RsaKey context in the
1080 key generation process in lib/silccrypt/rsa.c. The key length
1081 is now used to figure out the maximum size of the block allowed
1082 to be encrypted/signed.
1084 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1085 is equivalent to the silc_mp_mp2bin but does not allocate any
1088 * Changed silc_mp_mp2bin API to take length argument. If it is
1089 non-zero then the buffer is allocated that large. If zero, then
1090 the size is approximated using silc_mp_sizeinbase, which however
1093 * Created Global RNG API which is global RNG that application can
1094 initialize. After initializing, any routine anywhere in the
1095 code (including library) can use RNG without allocating a new
1096 RNG object. This was done to allow this sort of use of the
1097 RNG in code that has no chance to allocate RNG object. All
1098 applications currently allocate this and many routines in the
1099 library use this. Affected file lib/silccrypt/silcrng.[ch].
1101 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1102 it to use the Global RNG API.
1104 * Defined Authentication Payload into protocol specification that
1105 is used during SILC session to authenticate entities. It is
1106 used for example by client to authenticate itself to the server
1107 to obtain server operator privileges.
1109 Implemented this payload into the lib/silccore/silcauth.[ch].
1110 Implemented also routines for public key based authentication
1111 as the new protocol specification dictates.
1113 Moved definitions of different authentication methods from
1114 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1116 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1117 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1118 silc_pkcs_verify_with_hash functions into the file
1119 lib/silccrypt/silcpkcs.[ch].
1121 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * The client entry's userinfo pointer must be always valid.
1124 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1125 will fail since it requires the userinfo. Now, the userinfo
1126 is allocated as "" if actual userinfo does not exist. Actually,
1127 it must exist and it is totally Ok to drop client connections
1128 that does not announce the userinfo. However, we will make
1129 this workaround for now.
1131 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1132 to return the remote port by socket.
1134 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1136 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1137 SILC_SERVER_PENDING_EXEC and added an new macro
1138 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1139 data or when error occurs while processing the pending command.
1141 Added new argument `destructor' into silc_server_command_pending
1142 and to the SilcServerCommandPending object. This destructor is
1143 now called after calling the pending callback or if error occurs
1144 immediately. If error occurs the actual pending callback won't
1145 be called at all - only the destructor. The destructor may be
1146 NULL if destructor is not needed.
1148 All this applies for client library code as well. Similar
1149 changes were made there as well for the pending commands.
1151 In the client, the application must now allocate the
1152 SilcClientCommandContext with the silc_client_command_alloc
1155 * Added reference counter to the SilcServerCommandContext. Added
1156 function silc_server_command_alloc and silc_server_command_dup
1159 Same type of functions added to the client library for the same
1162 * Removed the cmd_ident from IDListData away since it is now
1163 global for all connections. It is the command identifier used
1164 in command sending and with pending commands. The affected file
1167 * Added reference counter to the SilcSocketConnection objecet to
1168 indicate the usage count of the object. The object won't be
1169 freed untill the reference counter hits zero. Currently only
1170 server uses this, and client ignores it. The client must be
1171 set to use this too later. The affected files are
1172 lib/silccore/silcsockconn.[ch]. Added also the function
1173 silc_socket_dup to increase the reference counter.
1175 This was mainly added because it is possible that the socket
1176 is removed underneath of pending command or other async
1177 operation. Now it won't be free'd and proper DISCONNECTING
1178 flags, etc. can be set to avoid sending data to connection that
1179 is not valid anymore.
1181 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1182 the connection. After that it sets SILC_SET_DISCONNECTED.
1183 It is, however, possible that the socket data is not still freed.
1184 The silc_server_packet_process now checks that data is not
1185 read or written to connection that is DISCONNECTED. The socket
1186 get's freed when the reference counter hits zero.
1188 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Changed the client operation API: channel_message operation's
1191 `sender' is now the client entry of the sender, not the nickname
1192 and the `channel' is the channel entry, not the channel name.
1194 In the private_message operation the `sender' is now also the
1195 client entry of the sender not the nickname.
1197 Affected file is lib/silcclient/ops.h and all applications
1198 using the client operations.
1200 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Moved the calling of ops->connect() from connect_to_server_final
1203 into receive_new_id functin since that is the point when the
1204 client is actually allowed to send traffic to network. The
1205 affected file is lib/silcclient/client.c.
1207 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1210 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1211 (if needs broadcasting) instead of broadcasting the packets one
1212 by one which would make a burst in the network traffic.
1214 * Added `broadcast' argument to the functions in silcd/server.[ch]
1215 silc_server_create_new_channel[_with_id] to indicate whether
1216 to send New Channel packet to primary router.
1218 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Added new function into the silcd/server.[ch] files:
1221 silc_server_create_new_channel_with_id to create new channel with
1222 already existing Channel ID.
1224 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1225 lib/silccore/silcpacket.h. This packet is used t send list of
1226 Set Mode payloads inside one packet. Server uses this to set
1227 the modes for the channels and clients on those channels, that it
1228 announced to the router when it connected to it. The protocol
1229 specification has been updated accordingly.
1231 * The silc_server_new_channel did not handle the packet coming
1232 from normal server as it normally does not send that. However,
1233 when it announces its channels it does send it. Implemented
1234 the support for that.
1236 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1237 into the file lib/silccore/id.h.
1239 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Fixed memory leaks in the functions silc_idlist_del_client,
1242 silc_idlist_del_channel and silc_idlist_del_server in the file
1243 silcd/idlist.c. All of those leaked like a sieve.
1245 * Fixed some small memory leaks in the client's function
1246 silc_client_notify_by_server.
1248 * Added functions into silcd/server.c: silc_server_announce_clients,
1249 silc_server_announce_channels and silc_server_announce_server.
1250 These functions are used by normal and router server to announce
1251 to its primary router about clients, channels and servers (when
1252 router) that we own. This is done after we've connected to the
1255 These functions effectively implements the following packet types:
1256 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1257 and SILC_PACKET_NEW_ID_LIST.
1259 * Added new functions into the silcd/packet_receive.[ch]:
1260 silc_server_new_id_list, silc_server_new_channel_list and
1261 silc_server_new_channel_user_list to handle the incoming
1262 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1264 * Added support of changing Channel ID in the function
1265 silc_server_replace_id. If the server that announces a channel
1266 to the router already exists in the router (with same name but
1267 with different Channel ID), router is responsible to send
1268 Replace ID packet to the server and force the server to change
1269 the Channel ID to the one router has.
1271 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1272 client that the Channel ID has been changed by the router. The
1273 normal server sends this to the client. Client must start using
1274 the new Channel ID as the channel's ID.
1276 Implemented handling of this new type into lib/silcclient/client.c
1277 into the function silc_client_notify_by_server.
1279 * Added new function silc_idlist_replace_channel_id into the files
1280 silcd/idlist.[ch] to replace the Channel ID.
1282 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Call silc_server_command_identify_check always when processing
1285 the IDENTIFY command in silcd/command.c
1287 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1290 send keepalive packets. The packet can be sent by clients,
1291 servers and routers.
1293 Added function silc_socket_set_heartbeat into the file
1294 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1295 If not set, the heartbeat is not performed. The actual
1296 heartbeat is implemented in the low level socket connection
1297 library. However, application is responsible of actually
1300 Added silc_server_send_heartbeat to send the actual heartbeat
1301 packet into silcd/packet_send.[ch]. Server now performs
1302 keepalive with all connections.
1304 * Added silc_task_get_first function into lib/silcutil/silctask.c
1305 to return the timeout task with shortest timeout. There was a bug
1306 in task unregistration that caused problems. TODO has been
1307 updated to include that task system must be rewritten.
1309 * The client library will now resolve the client information when
1310 receiving JOIN notify from server for client that we know but
1311 have incomplete information.
1313 * Rewrote parts of silc_server_remove_from_channels and
1314 silc_server_remove_from_one_channel as they did not remove the
1315 channel in some circumstances even though they should've.
1317 * Encryption problem encountered in server:
1319 The LEAVE command used to send the Channel Key packet to the
1320 router immediately after generating it. However, the code
1321 had earlier sent Remove Channel user packet but not immediately,
1322 ie. it was put to queue. The order of packets in the router
1323 was that Channel Key packet was first and Remove Channel User
1324 packet was second, even though they were encrypted in the
1325 reverse order. For this reason, MAC check failed. Now, this
1326 is fixed by not sending the Channel Key packet immediately but
1327 putting it to queue. However, this is more fundamental problem:
1328 packets that are in queue should actually not be encrypted
1329 because packets that are sent immediately gets encrypted
1330 actually with wrong IV (and thus MAC check fails). So, packets
1331 that are in queue should be encrypted when they are sent to
1332 the wire and not when they put to the queue.
1334 However, the problem is that the current system has not been
1335 designed to work that way. Instead, the packet is encrypted
1336 as soon as possible and left to the queue. The queue is then
1337 just purged into wire. There won't be any fixes for this
1338 any time soon. So, the current semantic for packet sending
1341 o If you send packet to remote host and do not force the send
1342 (the packet will be in queue) then all subsequent packets to the
1343 same remote host must also be put to the queue. Only after the
1344 queue has been purged is it safe again to force the packet
1347 o If you send all packets immediately then it safe to send
1348 any of subsequent packets through the queue, however, after
1349 the first packet is put to queue then any subsequent packets
1350 must also be put to the queue.
1352 Follow these rules and everything works fine.
1354 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Added new function silc_server_remove_clients_by_server to
1357 remove all client entries from ID list when the server connection
1358 is lost. In this case it is also important to invalidate all
1359 client entires as they hold the invalid server entry. This
1360 fixes fatal bug when server has lost connection and will reconnect
1363 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Made some sanity checks to silc_server_daemonise like to check
1366 whether the requested user and group actually exists.
1368 * Added sanity check to SKE's silc_ske_responder_finish to check
1369 that the public and private key actually is valid.
1371 * Invalidate the client's nickname when receiving Replace ID
1372 packet and the Client ID is being replaced. This means that the
1373 server will query the nickname if someone needs it (client)
1376 * Sort the ID Cache in client library when the ID Cache data
1377 has changed (needs sorting).
1379 * Do not allow for SILC client to create several connections to
1380 several servers. The client does not support windows right now
1381 and generating multiple connections causes weird behaviour.
1383 Irssi-silc client does support windows and can handle several
1384 connections without problems, see: www.irssi.org and SILC plugin.
1386 * Fixed some places where client was added to the IDList. The
1387 rule of thumb is following (in order to get everything right):
1388 If the client is directly connected local client then the
1389 `connection' argument must be set and `router' argument must be
1390 NULL to silc_idlist_add_client function. If the client is not
1391 directly connected client then the `router' argument must
1392 bet set and the `connection' argument must be NULL to the
1393 silc_idlist_add_client function.
1395 * The funtion silc_server_packet_send_local_channel actually did
1396 not check whether the client was locally connected or not. It
1397 does that now. Fixed a bug related to LEAVE command.
1399 * Fixed Remove Channel User payload parsing bug in server's
1400 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1402 * The server's silc_server_save_channel_key now checks also the
1403 global ID list for the channel as it might not be in the local
1404 list. Fixed a bug related to LEAVE command.
1406 * Is this the end of the [<unknown>] buglet that has been lurking
1407 around for a long time? A little for loop fix in server's
1408 silc_server_command_whois_parse that is used by both IDENTIFY
1409 and WHOIS command. At least, this was a clear bug and a cause
1410 of one type of [<unknown>] buglet.
1412 * WHOIS and IDENTIFY commands call the function
1413 silc_server_command_[whois/identify]_check function even if
1414 we are not router server.
1416 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Added --with-gmp configuration option. If set the GMP
1419 is always compiled in the SILC source tree. If not set then
1420 it is checked whether the system has the GMP3 installed. If
1421 it has then the GMP won't be compiled (the system's headers
1422 and library is used), if it doesn't have it then the GMP is
1423 compiled in the SILC source tree.
1425 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1427 * Changed RSA private exponent generation to what PKCS #1
1428 suggests. We try to find the smallest possible d by doing
1429 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1430 not security fix but optimization.
1432 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Added new config entry [Identity] to fork the server and run
1435 it as specific user and group. A patch from Bostik.
1437 * Imported Dotconf configuration library into lib/dotconf.
1438 This will be used to create the SILC configuration files later.
1439 It will appear in the distsribution after this commit.
1441 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * A big code auditing weekend happening. Auditing code for
1444 obvious mistakes, bugs and errors. Also, removing any code
1447 Removed files for being obsolete:
1449 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1450 inline in the file lib/silcutil/silcbuffer.h)
1452 o lib/silcutil/silcbufutil.c (the header has inline versions)
1454 Changed code to fix possible error conditions:
1456 o The buffer formatting routines now check that the destination
1457 buffer really has enough space to add the data. This applies for
1458 both buffer formatting and unformatting
1459 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1460 unformatting was changed to accomodate following rules:
1461 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1462 sent to the function while XXX_*STRING will not allocate or copy
1463 the data into the buffer. Instead it sets the pointer from the
1464 buffer into the pointer sent as argument (XXX_*STRING used to
1465 require that the pointer must be allocated already). This change
1466 makes this whole thing a bit more consistent and more optimized
1467 (note that the data returned in the unformatting with XXX_*STRING
1468 must not be freed now). The routines return now -1 on error.
1470 o Tried to find all code that use buffer_format and buffer_unformat
1471 and added return value checking to prevent formatting and
1472 especially unformatting errors and possible subsequent fatal
1475 o Changed ske->x and ske->KEY to mallocated pointers in
1476 lib/silcske/silcske.h. Fixed possible data and memory leak.
1478 o Added return value checking to all *_parse* functions. Fixed
1479 many memory leaks as well.
1481 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1482 so that buffer overflows would not happen. All code now also
1483 checks the return value as it can fail.
1485 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Added reconnection support to server if the normal server looses
1488 its connection to the router (for example if router is rebooted).
1489 The server performs normal reconnection strategy implemented
1490 to the server. Affected file silcd/server.c.
1492 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Added new packet type SILC_PACKET_SET_MODE that is used to
1495 distribute the information about changed modes (for clients,
1496 channels and clients channel modes) to all routers in the
1497 network. Updated the protocol specification accordingly.
1499 Added functions into silcd/packet_send.c and
1500 silcd/packet_receive.c: silc_server_send_set_mode,
1501 silc_server_set_mode.
1503 Added new files silcmode.[ch] into lib/silccore that implements
1504 the encoding and decoding of Set Mode Payload. Added new type
1505 SilcSetModePayload. Moved the definitions of different modes
1506 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1508 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Oops, a little mistake in server's connection authentication
1511 protocol. The protocol is not ended with FAILURE but with
1512 SUCCESS if the authentication is Ok. :) Affected file is
1515 * Implemented NICK_CHANGE notify handling in server in the file
1516 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1517 the local clients on the channel. After the changing nickname
1518 in router environment snhould work and the [<unknown>] nickname
1519 should appear no more.
1521 The silc_server_replace_id function that receives the Replace ID
1522 payload now sends the NICK_CHANGE notify type also in the file
1523 silcd/packet_receive.c
1525 * Changed WHOIS and IDENTIFY command to support the maximum amount
1526 of arguments defined in protocol specs (3328 arguments). This
1527 fixed a bug that caused problems when there were more than three
1530 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Added extra parameter, command identifier, to the
1533 silc_client_send_command so that explicit command identifier
1536 Changed that ID list routines uses specific command identifier
1537 when sending WHOIS/IDENTIFY requests to the server so that they
1538 can be identified when the reply comes back.
1540 Affected files lib/silcclient/command.[ch],
1541 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1543 * Added `sender' argument to silc_server_packet_send_to_channel
1544 to indicaet the sender who originally sent the packet to us
1545 that we are now re-sending. Ignored if NULL. Affected file
1546 silcd/packet_send.[ch].
1548 * Added some server statistics support in silcd/server_internal.h
1549 SilcServerStatistics structure and around the server code. Also
1550 send some nice statistics information when client is connecting
1553 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Fixed channel ID decoding in server's JOIN command reply in
1556 silcd/command_reply.c
1558 * Fixed braodcasting of replace ID payload to not to send it if
1559 we are standalone server in silcd/packet_receive.c.
1561 * Fixed all channel message sending routines to not to send
1562 packets to clients that has router set, since they are routed
1563 separately in the same function earlier. Affects file
1564 silcd/packet_send.c and all channel packet sending functions.
1566 * In USERS reply, res_argv[i] are not allocated, the table
1567 is allocated. Thus changed that free the table, not its
1570 * In server's whois_check and identify_check if the client is
1571 locally connected do not send any WHOIS commands - they are not
1574 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Fixed some minor bugs in client when sending WHOIS command. The
1577 arguments was in wrong order.
1579 * Removed statis function add_to_channel from server in
1580 silcd/command.c that was previously used with the joining but
1583 * Tested USERS command in router environment successfully with two
1584 routers, two servers and two clients.
1586 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Reorganized the USERS command and command reply in client library
1589 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1590 When the command is given by user we register a pending command
1591 callback that will reprocess the command after the reply has been
1592 received from the server. When reprocessing the packet we then
1593 display the information. Thus, the USERS information is displayed
1594 now in the command callback instead of in the command reply
1595 callback. The processing of the command is same as previously
1596 when server has sent the command reply in the JOINing process.
1598 * Added to USERS command in silcd/command_reply.c to join the client,
1599 we didn't use to know about, to the channel after we've created
1600 a client entry for it. Also, for clienet we did know already still
1601 check whether it is on the channel or not and add it if not.
1603 * Removed silc_server_command_join_notify as the function and its
1606 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Changed the client's pending command handling to the same as the
1609 server's pending command handling. It is also now possible to
1610 execute command reply functions from other command reply
1611 function as the function callbacks for commands and command
1612 replies are one and same. The pending commands are not static
1613 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1614 in client connection context. Thus, pending commands are server
1615 connection specific as it is convenient.
1617 Changed the function silc_client_command_pending and
1618 silc_client_command_pending_del and added new function
1619 silc_client_command_pending_check. Removed the
1620 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1623 * Added cmd_ident, current command identifier, to the client
1624 connection context in lib/silcclient/client.h to keep track on
1625 command identifiers used in command sending. Client's command reply
1626 function handling now supports the mandatory command identifiers.
1628 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1629 funtions in client to fully support pending command callbacks.
1631 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1632 as one of the arguments to the application in the command reply
1635 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1636 before first releasing SILC but came back. Now it is removed again
1637 and should come back nomore. The FORWARDED flag was used only
1638 by the JOINing procedure by forwarding the command packet to router.
1639 Now, the JOINing procedure has been changed to more generic (due
1640 to various router environment issues) and FORWARDED is not needed
1641 anymore for anything. The protocol specification is yet to be
1644 Now, removed silc_server_packet_forward from server and the flag
1645 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1647 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Renamed NAMES command to USERS command. The NAMES was named that
1650 due to historical reasons. Now it is renamed. Also, rewrote
1651 parts of the USERS command. The nickname list is not sent anymore
1652 by the server. Only Client ID and mode lists are sent in the USERS
1653 command. Changed this also to the protocol specification.
1655 The client now resolves the names and stuff after it receives
1656 the USERS list from the server when joining to the channel.
1658 * WHOIS and IDENTIFY commands has been changed to support multiple
1659 Client ID's per command. One can now search for multiple users
1660 in the network by sending only one WHOIS or IDENTIFY command.
1661 Changed the code and the protocol specifications.
1663 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1664 uses silc_server_command_whois_parse to parse the request. */
1666 * If normal server, do not parse the WHOIS and IDENTIFY requests
1667 before sending it to the router. Saves some time.
1669 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Fixed JOIN command on client library. Wrong number of arguments
1672 used to crash the client.
1674 * Added silc_server_channel_has_global function to check whether
1675 channel has global users or not.
1677 * Added silc_server_channel_has_local function to check whether channel
1678 has locally connected clients on the channel.
1680 * The silc_server_remove_from_one_channel now checks whether the
1681 channel has global users or not after given client was removed from
1682 the channel. It also checks whether the channel has local clients
1683 on the channel anymore. If it does not have then the channel entry
1684 is removed as it is not needed anymore.
1686 * The silc_server_notify now checks on JOIN notify whether the joining
1687 client is one of locally connected or global. If it is global then
1688 the channel has now global users on the channel and that is marked
1689 to the channel entry. Also, it now saves the global client to
1690 global list who is joining and JOINs it to the channel. This is
1691 for normal server, that is.
1693 Changed silc_server_send_notify_on_channel,
1694 silc_server_packet_relay_to_channel and
1695 silc_server_packet_send_to_channel check if we are normal server
1696 and client has router set (ie. global client) do not send the
1697 message to that client, as it is already routed to our router.
1699 * Implemented LEAVE notify type handling in silc_server_notify
1702 * Tested LEAVE command in router environment successfully. Tested
1703 with two routers, two servers and two clients.
1707 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1709 * Implemented SIGNOFF notify type handling in silc_server_notify
1712 * silc_server_remove_id now removes the client entry from all channels
1713 it has joined and thusly sends SIGNOFF notify type.
1715 * Rewrote the NAMES list generation in server by removing two excess
1716 loops. The lists are created now inside one loop.
1718 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * silc_server_remove_channel_user checks now also global list
1721 for channel and client.
1723 * silc_server_new_channel_user checks now both local and global
1724 list for channel and client. Fixed a bug in client id decoding.
1725 Used to decode wrong buffer.
1727 * silc_server_channel_message checks now both local and global
1728 list for channel entry.
1730 * Tested channel joining (hence JOIN) in router environment
1731 successfully. Tested with two routers, two servers and two
1734 * Tested channel message sending in router environment successfully.
1736 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * Added silc_server_save_channel_key into server.[ch] to save the
1739 received channel key in Channel Key payload processing. It is
1740 also used in JOIN command reply handling.
1742 Equivalent function silc_client_save_channel_key added into
1743 client.[ch] into client library.
1745 * Changed JOIN command reply to send information whether the channel
1746 was created or not (is existing already) and the channel key
1747 payload. Changed protocol specs accordingly.
1749 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1750 the request was sent by ID and not by nickname. Crashed on
1753 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1756 now correctly save the received data.
1758 * silc_server_free_sock_user_data now notifies routers in the
1759 network about entities leaving the network.
1761 At the same time implemented functions silc_server_remove_id
1762 and silc_server_send_remove_id to receive and send REMOVE_ID
1763 packets. The packet is used to notify routers in the network
1764 about leaving entities. The ID removed will become invalid in
1767 * Added function silc_idlist_del_server into server. Removes and
1768 free's server entry from ID list.
1770 * silc_server_private_message function now checks, if we are router,
1771 that the destination ID really is valid ID, naturally.
1773 * In router when NEW_ID packet is received (for new client) the
1774 hash of the Client ID is saved in the ID Cache but the
1775 client->nickname is set to NULL, instead of putting the hash
1778 IDENTIFY command now also checks that client->nickname must be
1779 valid. If it is not if will request the data from the server who
1780 owns the client. Added new function
1781 silc_server_command_identify_check.
1783 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1784 to set the command to already allocated Command Payload.
1786 * Tested private message sending in router environment with two
1787 routers, two servers and two clients. Fixed minor bugs and now
1790 * Fixed segfault from client's NAMES command. Used to crash if
1793 * Forwarded packets must not be routed even if it is not destined
1794 to the receiver. Changed server code comply with this.
1796 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added `require_reverse_mapping' boolean value to ServerParams
1799 structure. If TRUE (not default) the server will require that
1800 the connecting host has fully qualified domain name.
1802 If the reverse mapping is not required and hostname could not be
1803 found the IP address is used as hostname.
1805 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Implemented version string checking to both client and server.
1808 The check is incomplete currently due to the abnormal version
1809 strings used in development version of SILC.
1811 * Changed all command functions in server to use the new
1814 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * Changed char *data to unsigned char *data in ID Cache system to
1817 support binary data as ID Cache data. Changed code to support
1818 binary data in lib/silccore/idcache.c.
1820 * Renamed silc_server_packet_relay_command_reply to
1821 silc_server_command_reply as it is normal packet receiving
1822 function. Rewrote the function to accept command replys for
1823 servers and not only for clients.
1825 * Mark remote router always as registered server if we are connecting
1826 to it. Otherwise, commands sent by the router to us are ignored.
1828 * All ID List find routines now returns the ID Cache Entry pointer
1829 as well if requested.
1831 * WHOIS command works now in router environment, tested with two
1832 routers, two servers and two clients.
1834 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1835 in router environment (as it is almost equivalent to WHOIS) but
1836 hasn't been tested thoroughly. Added new functions:
1838 silc_server_command_identify_parse
1839 silc_server_command_identify_send_reply
1840 silc_server_command_identify_from_client
1841 silc_server_command_identify_from_server
1843 * Disabled route cache adding because adding two different ID's with
1844 same IP replaces the old cache entry thus giving wrong route.
1845 The entry->router->connection is always the fastest route anyway
1846 so route cache may not be needed. Of course, new routes maybe
1847 established after receiving the ID when the entry->router->connection
1848 might not be anymore the most optimal.
1850 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Add route cache for received ID for fast routing.
1854 * Added silc_server_packet_route to route received packet on router
1855 that is not destined to us.
1857 * Renamed silc_server_get_route to silc_server_route_get.
1859 * Added id_string and id_string_len fields into SilcServer to
1860 include encoded ServerID for fast comparing without excess
1861 encoding of the ID's.
1863 * Cleaned up WHOIS command on server side. Added following static
1866 silc_server_command_whois_parse
1867 silc_server_command_whois_check
1868 silc_server_command_whois_send_reply
1869 silc_server_command_whois_from_client
1870 silc_server_command_whois_from_server
1872 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1873 arguments in command replies. All command functions should be
1874 updated to use this macro.
1876 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Minor typo fixes on command reply handling on server.
1880 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Added silc_server_command_add_to_channel internal routine to add
1883 the client to the channel after router has created the channel and
1884 sent command reply to the server.
1886 * Added generic silc_server_send_command to send any command from
1889 * Use static buffer with ID rendering instead of duplicating data.
1891 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Fixed a channel user mode bug when joining to a channel server gave
1894 everybody channel founder rights, oops.
1896 * We mark ourselves as the router of the incoming server connection
1897 if we are router ourselves. This way we can check in some packet
1898 sending functions whether it is locally connected server. For
1899 incoming router connections we put NULL.
1901 * For router sending packets locally means now always sending the
1902 packet cell wide; to local clients and local servers. For normal
1903 server sending packet locally means sending it to only local
1906 * Fixed the JOIN command to really work in router environment. If the
1907 channel is created it is always created by the router. Router is
1908 also responsible of making the initial joining to the channel,
1909 sending JOIN notify to the sending server and distributing
1910 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1911 does not exist server doesn't do anything else but forward the
1912 command to the router which performs everything.
1914 * Added silc_server_send_channel_key function to send the Channel Key
1917 * Added silc_server_create_channel_key to create new channel key. The
1918 channel key is now re-generated everytime someone joins or leaves
1919 a channel, as protocol dictates. Note: channel->key_len is the
1922 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1925 packet_receive.[ch] to separate packet sending and receiving
1926 routines. The server.[ch] now includes everything else including
1927 actual packet processing (writing and reading data) and other
1930 Renamed silc_server_private_message_send_internal to
1931 silc_server_send_private_message. The routine is still though
1932 used only to relay private messages as server does not send
1933 private messages itself.
1935 Renamed silc_server_new_channel to silc_server_create_new_channel
1936 and added new function sicl_server_new_channel that handles the
1937 incoming New Channel packet. Added also new sending function
1938 silc_server_send_new_channel to send New Channel Payload.
1940 * Added new function silc_server_notify to process incoming notify
1941 packet to the server/router. Server may then relay the notify
1942 to clients if needed.
1944 * Added new function silc_server_new_channel_user to process incoming
1945 New Channel User packet. Router will redistribute the packet and
1946 send JOIN notify to its local clients and locally connected servers
1947 if needed. Normal server will send JOIN notify to its local client
1948 on same channel when received this packet. Added also corresponding
1949 sending function silc_server_send_new_channel_user to sent the
1952 * Added boolean route argument to send_notif_to_channel and
1953 packet_send_to_channel functions to attempt to route the packet
1954 if it is TRUE and send only locally if it is FALSE.
1956 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * silc_server_replace_id now broadcasts the received replace ID
1959 packet if it is not broadcast packet already. The router must
1960 broadcast to inform other routers about changed ID.
1962 * Added backpointer to server's router into SilcServer context in
1963 silcd/server_internal.h.
1965 * Fixed silc_server_packet_broadcast to send correct broadcast
1968 * The channel key is now distributed to the local client as soon
1969 as it is received from the router (in router environment) so that
1970 no other packet may be sent for the channel until client has
1973 * silc_server_remove_channel_user now broadcasts the received
1974 Remove Channel User packet if it is not broadcast packet already.
1975 The router must broadcast to inform other routers about removed
1978 * Added users field into SilcPacketContext that is a reference count
1979 of the context. One can increase the reference count by calling
1980 silc_packet_context_dup which is now changed to just increase the
1981 reference count instead of duplicating the data. The reference
1982 count is decresed by calling silc_packet_context_free that will
1983 free the data after the reference count hits zero.
1985 For now on the packet context and everything allocated into it
1986 (including the raw packet from network) must be freed by calling
1987 the new silc_packet_context_free function. Added also new function
1988 silc_packet_context_alloc that must be used now to allocate the
1989 context. This also means that if a routine is asynchronous from
1990 silc_[client/server]_packet_parse_type the packet context must
1991 be duplicated by calling silc_packet_context_dup. Otherwise it
1992 gets free'd after silc_[client/server]_packet_parse_type returns.
1993 Also, one must remember that if packet is duplicated then its
1994 reference count must be decresed by calling the free function as
1995 many times as it was duplicated.
1997 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1998 from both client and server.
2000 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Made joining to a channel working in router environment.
2004 * Cleaned up JOIN command on server side and create function
2005 silc_server_command_join_channel internal routine to make the
2008 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Changed silc_command_pending list to SilcDList. Also, added
2011 `ident' field to SilcServerCommandPending structure to identify
2012 the reply and to call correct callback.
2014 Added silc_server_command_pending_check function to replace the
2015 corresnponding macro. The silc_command_pending list is not
2018 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2019 to set identifier to previously allocated Command Payload. It
2020 is used to set identifier for command when resending Command
2023 * Added silc_command_payload_encode_payload to encode Command
2024 Payload buffer from SilcCommandPayload structure.
2026 * Added silc_argument_payload_encode_payload to encode Argument
2027 payload buffer from SilcArgumentPayload structure.
2029 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Changed WHOIS command to support router connection on server side.
2032 The whois request is always sent to router unless the server is
2033 standalone server. After server has received the reply from the
2034 router will it send the reply to the client.
2036 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2037 broadcast received broadcast packet. The function is used only
2038 by router. The broadcast packet is always sent to the router's
2041 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2042 render given ID to printable string, for log files for example.
2044 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Made basic router to router connections working. At least they
2047 can now connect to each other but nothing really works the way
2048 they are supposed - yet.
2050 * Added new initiator token to RouterConnection configuration
2051 file in silcd/serverconfig.[ch]. It is used to tell whether we
2052 are the initiator to the remote router or whether we'll expect
2053 the other end to connect.
2055 * Moved registering of listener task to silc_server_init, hence
2056 the server starts listenning as soon as it is run, even if it
2057 does not have connections to other routers. Let's see how well
2060 * Changed default connection retry timeouts for more suitable in
2063 * Removed cipher and such arguments from silc_idlist_add_client
2064 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2065 Added new function silc_idlist_add_data to add the keys and stuff
2068 * Added SilcIDListData structure and added it to SilcClientEntry
2069 and SilcServerEntry as their first field in the structure. This
2070 way we can explicitly cast the ID entries to the SilcIDListData
2071 structure and get common data for the entries. In past, we had
2072 to first check what type of connection it is and then cast it to
2073 correct ID entry type. Now, we can directly cast the opaque
2074 pointer to the SilcIDListData (no matter what ID entry it actually
2075 is) and get the data needed.
2077 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2080 in some circumstances even if threre were timeout tasks, though not
2081 IO tasks, but tasks anyway. Now fixed.
2083 * Defined SilcServerConnection structure to hold connection specific
2084 stuff about directly connected servers and routers. The definition
2085 is currently in silcd/server_internal.h. I thought about having
2086 a bit more important role fro this struct but for now it is used
2087 only when connecting to other server (or router actually).
2089 * Added connecting retry support in server when connecting to
2090 router(s). The retry feature implement exponential backoff
2091 algorithm. Also, added SilcServerParams structure to hold default
2092 parameters for server. For now, it include these retry settings
2093 and are hard coded. After server is moded to be as Silc Server
2094 Library this structure will be more important.
2096 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Changed client librarys channel->clients table to SilcList and
2099 changed code accordingly.
2101 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Changed client's channel table to SilcList and changed code
2104 accordingly. Also changed SilcChannelClientEntry to include back-
2105 pointer to the channel so that client entry can use that structure
2106 as list as well and we have fast cross-reference to the channel.
2107 This change dramatically decreased the complexity of channel
2108 handling with client entry and vice versa (removed one extra
2109 loop when searching for channel entry from many functions).
2111 * Changed server->sim from table to SilcDList and changed code
2114 * NAMES command can now be used from user interface. It will show
2115 the user list on the channel, neatly.
2117 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2118 Code now saves realname of the user if it becomes available.
2120 * Renamed configure.in to configure.in.pre and made ./prepare
2121 script to automatically add correct version string to
2122 configure.in which it creates from configure.in.pre.
2124 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * NAMES command reply now shows users mode with the nickname when
2129 * Moved silc_client_ch[u]mode[_char] functions from
2130 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2131 place sucks, they are utility functions and should be in some
2134 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2136 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2139 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added TRQ (efficient deque and list library) into lib/trq. This is
2144 a very good list library that is currently used in the SILC. Defined
2145 SilcList API over the library because I didn't like the API very
2146 much. See lib/trq/silclist.h for the API and examples of how to
2147 use the API. Fixed various places in the code to use the new
2148 SilcList API. The SilcList is meant for lists that has a structure
2149 already defined as a list. It is not suitable to add just some
2150 context to the list (in TRQ, the context is the list actually).
2152 So, I defined SilcDList that can be used for the purpose where
2153 predefined list structure does not exit. This can be used as
2154 such list. Now some context just can be added to the SilcDList.
2155 Currently this list is not used in the SILC just yet, though there
2156 are a lot places where this can replace dynamically allocated
2157 tables and I will fix these places, later, to use SilcDList.
2158 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2159 and use TRQ internally).
2161 Also fixed some annoying warning messages that the original TRQ
2162 code generated. Also minor changes to TRQ's Makefile.in.
2164 * Added support for querying by Client ID to both WHOIS and
2165 IDENTIFY commands into server, as required by the protocol.
2167 * Removed method function pointers from SilcBuffer structure. They
2168 weren't used to anything and just increased the context size for
2169 no good reason. This change also made silc_buffer_alloc and
2170 silc_buffer_free functions inline functions.
2172 * Disabled command flooding detection support until it's fixed so
2173 that it accepts commands in but does not execute them more than once
2176 * Added silc_net_localhost(), to return local hostname, into
2177 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2178 that must be initialized before calling silc_client_init.
2180 * Added new function: silc_server_send_notify_on_channels to send
2181 notify messages to all channels client has joined. It is assured
2182 that the message is sent only once per client.
2184 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2185 lib/silcutil/silcutil.[ch] as silc_format function. The new
2186 function is generic and is used by server as well, not only by
2187 the logging routines.
2189 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2190 the provided version string was not acceptable. Added new function:
2191 silc_ske_check_version into lib/silcske/silcske.h. The function
2192 must be implemented by the application (client or server) and it
2193 does not reside in the SKE library. The function checks the version
2194 string remote end sent.
2196 * Added back pointers (to opaque context and to SilcSocketConnection)
2197 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2199 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2200 duplicate packet context structure.
2202 * Changed `notify' client operation to send same arguments as client
2203 receives from server except for ID's. ID's are mapped to correct
2204 ID entry and that is returned. Also, if channel entry is not sent
2205 by server but the notify is for channel the channel entry is sent
2206 to application (otherwise application doesn't know that it is for
2207 channel (library gets it from packet's Destination ID)).
2209 * Added silc_client_remove_from_channels into client library to
2210 remove a client from all channels it has joined to. Used when
2211 received SIGNOFF notify from server. Added also new function
2212 silc_client_replace_from_channels to replace old ID entry with
2213 new ID entry on all channels. Used when received NICK_CHANGE
2216 * Fixed ID Cache list handling in silc_idlist_get_client in
2217 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2218 to get (or query) client by ID.
2220 * Updated TODO list.
2222 * Added connection authentication status message defined by the
2223 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2224 support for these into the code in client and server side.
2226 * Added generic function silc_client_send_command to send any command
2227 with variable argument list. Application should use this function
2228 to send commands if the command functions provided by the library
2229 does not suite for the application's user interface needs.
2231 * Added new `failure' client operation. Application is notified about
2232 received failure packet if client is executing a protocol. In this
2233 case the protocol's execution has failed.
2235 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2236 is required by the protocol.
2238 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2239 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2242 * Added status flag to SilcSKE object to indicate realtime status
2243 of the SKE protocol.
2245 * Application receives now exactly same command reply arguments as
2246 the library receives from server. However, if ID is received the
2247 corresponding ID entry is returned to the application (eg. Client
2248 ID is mapped to correct SilcClientEntry entry and that is returned).
2249 Changed command_reply client operation due to this change.
2251 * Changed all ID's in commands and in command replys as ID Payloads.
2252 Change affected both client and server side codes.
2254 All ID's sent in SILC network (with execption of ID's in SILC
2255 Packet header) are sent in ID Payload to support variable length
2258 * Server now notifies nick changes and notifies all clients on
2259 the channels about the new nickname (about the new Client ID,
2262 * Implemented CMODE command to change channel modes. Supports all
2263 channel modes defined by the protocol specs except ban and invite
2264 lists. (Also, private channel key mode is supported but support for
2265 setting private channel key in client is missing, thus, this mode
2266 has no effect on client side (except that server requires that the
2267 client uses private channel key and normal channel traffic does not
2270 Also, invite mode works per se, but INVITE command does not work
2271 yet correctly, so you can set channel as invite only channel but
2272 inviting clients to the channel does not work (it is yet to be
2273 thought what's the best way to do it).
2275 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2276 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2277 Implemented CUMODE command to change user's mode on the channel.
2278 Supports all modes defined by the protocol specs.
2280 * Added NAMES command reply to return users modes on the channel.
2282 * Removed unnecessary and slow ciphers from lib/silccrypt.
2284 * Set SO_KEEPALIVE option to connection sockets by default.
2286 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2288 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2289 redefined the Notify Payload into protocol specs.
2291 * Added silc_id_payload_parse_id to get ID directly from raw
2294 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2297 accept searching by Client ID as well.
2299 * Added support for LEAVE and SIGNOFF notify types in client library.
2301 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2302 to parse ID Payload from raw data.
2304 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Added flags parameter into silc_ske_assemble_security_properties
2307 function in lib/silcske/silcske.[ch].
2309 * Changed notify client operation to fit better for notify messages
2310 sent by server. The notify payload received from server is now
2311 passed to the application (after parsing it to SilcNotifyPayload).
2312 It is application's responsibility to retrieve the arguments
2313 from the payload and show the message the way it wants. The message
2314 sent by server is implementation specific.
2316 * Changed public keys to comply with the protocol specification.
2317 Old public keys are not supported anymore and are not compatible.
2319 * Removed nickname from Channel Payload as the latest draft removed
2320 it. The client must resolve the nickname from the NAMES command
2321 reply received when it joined the channel.
2323 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2325 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Fixed some errors in protocol specification drafts.
2329 * Created lib/silccore/silcnotify.c to implement Notify Payload
2330 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2331 generic payloads described by protocol specifications. The file
2332 includes implementations for ID Payload and Argument Payload.
2334 * Changed Command Payload implementation to use the new Argument
2335 Payload. Changed command_xxxx_payload to command_payload_xxxx
2336 to comply with SILC coding conventions.
2338 * Added suppport for Argument Payload handling in Notify Payload
2339 implementation as protocol requires it. Added the new support
2340 into server and client lib as well.
2342 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added support for multiple nicknames on same channel. [n] is
2345 added locally to the nickname if there are more than one same
2346 nicknames on the channel.
2348 * Server now sends all nicknames that matched WHOIS request.
2349 Client also shows the list received from server.
2351 * Added TOPIC command to client side. User can now set and show
2352 current topic on channel.
2354 * Added MOTD command to client and server. Also, server sends the
2355 motd when client connects to the server.
2357 * Changed version strings to comply ISO 8601.
2359 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Fixed protocol error handling in client library. It should now
2362 cope even if the SKE fails for some reason.
2364 * Made new protocol specification drafts for submitting to IETF.
2366 * Implemented TOPIC command to server in silcd/command.c.
2368 * Added two new notify types into lib/silccore/silcnotify.h:
2369 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2370 notify nickname change and topic setting/change on a channel.
2372 * API change of command_reply operation in client library. The
2373 application gets now the status type received from server as well.
2375 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2379 * Cras fixed and optimized the packet handling even further and
2380 it should work now. Minor change to the prototype of function
2381 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2383 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Added new function into lib/silcutil/silcschedule.[ch]:
2386 silc_schedule_with_fd to select() a specified fd. The function
2387 returns after timeout expires or data arrives or goes. The
2388 function is used by packet routines to wait that all data is
2389 received from network.
2391 * Fixed data reading from network in lib/silccore/silcpacket.c.
2392 The code now assures that all data is read from the fd and then
2393 continues packet processing. This was a bug fix since the code
2394 used to drop some data in some circumstances.
2396 * Added new function into lib/silcclient/client.[ch]:
2397 silc_client_start_key_exchange to start key exchange after
2398 connection has been established to server. The code internally
2399 now uses this funtion but its main purpose was to provide it
2400 for applications that perform their own connecting. After
2401 application has created a connection it merely calls this
2402 function to start the key exchange between client and server.
2403 The library takes care of everything else after that.
2405 Updated also lib/silcclient/README to explain the usage of
2408 * Do not send to application information that connection has
2409 been established. Application gets notified it by connect
2412 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Applied cras's patch to add silc_schedule_one function. The
2415 function runs scheduler once and returns.
2417 * Fixed the scheduler after cras messed it up. The timeout
2418 handling works now as it's supposed to work.
2420 * Added into lib/silccore/ silcnotify.h to include notify
2421 message types support. Changed silc_server_send_notify*
2422 functions, in server.[ch], to support those new notify types.
2423 Added the support for the notify types into client library,
2424 as well. Added new notify client operation into ops.h in
2427 * Changed silc_server_packet_send_to_channel to send normal
2428 packets instead of just channel message packets. The function
2429 is now used to send the notify packets to channels. It is not
2430 used to send channel message packets anymore, as server never
2433 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2434 va_arg()s as it seems to require it nowadays. I guess, if SILC
2435 is compiled with older va_arg() the new code should work anyway.
2437 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Splitted core library. Core library (lib/silccore) includes
2440 now only SILC protocol specific core (and common) components.
2441 Created new utility library (lib/silcutil) that includes more
2442 generic purpose stuff. The stuff for util library was taken
2443 from the old core library. This was minor and easy split.
2445 * Created SILC Client Library (lib/silcclient) that includes
2446 implementation of the SILC client without user interface. This
2447 was major move from silc/ directory. The code has been changed
2448 so that it is transparent towards the user interface. The
2449 silc/ directory includes now the same user interface as before
2450 and it uses the new client library. Read lib/silcclient/README.
2451 Basicly, the client library performs everything else related
2452 to SILC except user interface handling. Also, configuration
2453 files are considered to be part of user interface and library
2454 does not handle them.
2456 This change also changed a lot of structures, function naming etc.
2457 Most important change was that SilcClientWindow object was
2458 renamed to SilcClientConnection in the client library. Created
2459 also new file lib/silcclient/ops.h. Also added new files
2460 silc/local_command.[ch] and silc/client_ops.[ch].
2462 All these changes were made to make it easier for user interface
2463 designers to create what ever user interface for the SILC client
2466 It is also expected that the server will be moved to lib
2467 directory as well and SILC Server Library will be created;
2468 sometimes in the future.
2470 * Removed Local commands from lib/silccore/silccommand.h as
2471 they are application specific and new client library does not
2472 handle any of those anymore.
2474 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2475 old client implementation in silc/.
2477 * Added support for callback functions in SILC_LOG_* macros.
2478 Application can now set its own callbacks that will be called
2479 instead of using the default functions that will always print
2480 the debug messages to stderr (or stdout). Also, debugging can
2481 now be disabled by setting silc_debug to FALSE and re-enabled by
2482 setting it to TRUE. Note, that logging will still work even
2483 if debugging is disabled.
2485 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2486 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2487 silc_log_reset_debug_callbacks.
2489 * To enable debugging in silc client one must give now -d
2490 option on command line.
2492 * Changed silc_schedule_init to automatically allocate task queues
2493 if they are not allocated before calling it.
2495 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Added GMP 3.1 into math library.
2499 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2502 a channel in SILC network. The packet is used by servers and
2503 routers to notify other routers that user has left a channel.
2504 This little feature was missing until now. Added the feature
2505 to protocol specification as well.
2507 Added functions: silc_server_send_remove_channel_user and
2508 silc_server_remove_channel_user into server.[ch].
2510 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2511 lib/silccore/silcpacket.h. However, they are not implemented
2514 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Fixed joining to a channel and sending channel messages
2517 between server and router. The channel message sending should
2518 now work inside a cell.
2520 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Fixed the private message sending between server and router.
2523 The private message sending should now work inside a cell.
2525 * Added silc_server_replace_id into server.[ch] to replace
2526 existing ID in the SILC network.
2528 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2529 and silc_idlist_replace_server_id into idlist.[ch] in server.
2531 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Fixed the server to server connections. Server can again now
2534 connect to router. Router to router connections probably does
2537 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Added dynamic protocol registering support. Now protocols can
2540 registered and unregistered on the fly. Patch by cras.
2542 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Added lib/contrib directory to hold routines that some platforms
2545 don't have but are needed by SILC.
2547 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2548 into lin/contrib to provide getopt() and getopt_long() for
2549 those who don't have it.
2551 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2553 * Added AWAY command to client. When away message is set and
2554 client receives a private message packet the client automatically
2555 replies to the sender with the away message.
2557 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2558 bug seemed to be the cause of recent problems when compiling
2561 * Added version detection support to SKE protocol specification
2562 and added the new changes to the SKE implementation as well.
2563 There were other minor changes in the SKE protocol as well.
2565 Many changes in lib/silcske/silcske.[ch] and in
2566 lib/silcske/payload.[ch].
2568 * Added ^U functionality, clear input line. Patch from cras.
2570 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Mainly small bugfixes on core library. Fixed some debugging
2573 logging and buffer overflow in silclog.c.
2575 * Updated config.sub and config.guess on the distribution tree.
2577 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Added command lagging support in server. Client may execute
2580 commands now only once in two seconds.
2582 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Optimized packet reception. MAC computation and checking is now
2585 also more optimized. A lot previously duplicated code is now
2586 used as generic by both client and server.
2588 * Fixed key pair generation in clientutil.c
2590 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Added into lib/silccore/silcbufutil.[ch] new function;
2593 silc_buffer_realloc.
2595 * Moved generic packet sending/encryption functions to
2596 lib/silccore/silcpacket.[ch] from client and server. Some
2597 rewriting of the functions.
2599 * Moved all generic packet reception/decryption functions to
2600 lib/silccore/silcpacket.[ch] from client and server. The
2601 packet processing is now much cleaner in both client and server.
2602 These were major changes in both client and server.
2604 * Created many common functions in server to do packet sending.
2605 Previously code were duplicated a lot, this has been removed
2608 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Rewrote major parts of the ID cache system. Don't know
2611 whether it is better now or not but at least the API is more
2614 * Major rewrite on ID cache stuff on client because of the ID
2615 cache API changes. Added idlist.c to client.
2617 * Also major rewrite on ID cache stuff on server as well.
2618 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2619 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2620 in hand, instead they are all put into the ID cache system now.
2621 All server_idlist_* routines uses ID cache now instead of
2622 traversing its own lists (those lists does not exist anymore).
2623 SilcIDList though still exists. Also, SilcXXXEntry's are
2626 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Finally made the SKE implementation compliant to the protocol
2629 specification. All mp integers are now binary encoded as
2630 opposed being HEX encoded.
2632 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2635 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2636 functions: silc_[encode/decode]_pem. Also added function
2637 silc_encode_pem_file to PEM encode with newlines ('\n') for
2640 * SILC public keys are now encoded either PEM or binary. Same
2641 option is for private keys as well. By default private keys
2642 are binary encoded and public keys PEM encoded. Silly HEX
2643 encoding were removed.
2645 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2646 function to create fingerprints.
2648 * Fixed a bug in SHA1; does not change the original data anymore.
2650 * Partly implemented INFO command on client and server side.
2651 Fixed CLEAR command. Changes to SERVER command; show current
2652 server(s) when giving command without arguments. Added
2653 VERSION command to client.
2655 * Added check to server that unregistered connections cannot
2656 execute commands (unless it is specificly allowed).
2658 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Fixed screen refresh.
2662 * Fixed channel joining bug from client. On some circumstances
2663 client tried to join to a channel it had already joined.
2665 * Added public key verification process into client's protocol.c.
2666 The client now verifies the public key from user and saves
2667 it into ~./silc/serverkeys/ directory.
2669 Added into: clientutil.[ch]: silc_client_verify_server_key.
2671 * Changed SKE protocol's silc_ske_initiator_finish function
2672 to accept callback function that verifies the received public
2673 key. Removed old silc_ske_verify_public_key function.
2675 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2678 silc_pkcs_private_key[_data]_set.
2680 * Made the password and public authentication more cleaner in
2681 server's protocol.c.
2683 * Removed historic and obsolete protocol `channel_auth' from
2684 both client and server.
2686 * Removed wrong way of sending command status messages from
2687 server to client in server's command.c. The old way violated
2688 protocol specification.
2690 Changes to silccore/silccommand.[ch]: removed
2691 silc_command_encode_status_payload -> not needed anymore,
2692 changed silc_command_encode_payload_va to accept extra
2693 argument on variable argument list. The argument type must
2694 now be provided to the function. Also, added new function:
2695 silc_command_encode_reply_payload_va which is same as
2696 normal command_encode_payload_va except command status type
2697 is provided as extra argument.
2699 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Added ~./silc directory handling. The directory includes the
2702 public and private keys for the client.
2704 Added silc_client_check_silc_dir, silc_client_create_identifier
2705 and silc_client_load_keys.
2707 * Implemented SILC protocol compliant public key. Added public
2708 and private key saving to and loading from files.
2710 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2711 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2712 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2713 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2714 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2716 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2717 silc_pkcs_load_[public/private]_key.
2719 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added silc_server_get_route (route.[ch]) to get connection
2722 data for the fastest route for given ID.
2724 * Implemented INVITE command on client and server. The command
2725 were re-defined in the SILC Protocol Specification and the
2726 implementation now complies with the specification.
2728 * Implemented PING command on client and server.
2730 * Implemented NAMES command on client and server. The server side
2731 supports currently only normal server not router server yet.
2732 Some changes to NAMES definition in SILC protocol specification.
2734 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Implemented LEAVE command on client and server.
2738 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2739 again. This change was made to the protocol as well. Server
2740 should not violate the protocol specification anymore.
2742 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2745 was tested. SOCKS4 was not but should work anyway.
