16 state of the protocol. Affected file is
17 lib/silccore/silcprotocol.[ch].
19 * Added the re-key support with and without PFS to the client
20 library. Re-key is performed once in an hour, by default.
22 * Removed the `hmac_key' and `hmac_key_len' fields from the
23 SilcClientConnection structure; not needed. Affected file is
24 lib/silcclient/client.h.
28 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * Do not ask whether user wants to use the negotiated private key
31 for private messages, just use it. Affected file is
34 * Added `send_enc_key' and `enc_key_len' fields to the
35 SilcIDListData structure since they are needed in the re-key
36 phase. Affected file is silcd/idlist.[ch].
38 * Implemented the simple re-key protocol into the server.
39 Affected files silcd/server.c and silcd/protocol.[ch]. The
40 re-key will be performed once in an hour, by default.
42 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
43 Added silc_server_rekey, silc_server_rekey_callback and
44 silc_server_rekey_final.
46 * Removed Tunneled flag from the protocol. Updated the code
47 and the specifications.
49 * Adde `pfs' field to the SilcIDListData to indicate whether

53 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
56 int64 of at least the xintXX size. If void * is less that 4
57 bytes uint32 * will be used. Defined bool as boolean.
59 * Changed _ALL_ unsigned long and unsigned int to uint32,
60 unsgined short to uint16 in the source tree.
62 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
63 not handle clients that has entry->data.registered == FALSE.
64 They are not in the network anymore. Affected file is
67 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Implemented the sending of the SERVER_SIGNOFF notify in the
70 server. Affected file is silcd/server.c.
72 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
73 Added also silc_notify_payload_encode_args into the
74 lib/silccore/silcnotify.[ch].
76 * Implemented ther SERVER_SIGNOFF notify handling in the server.
77 Affected file silcd/packet_receive.c.
79 * Implemented the SERVER_SIGNOFF notify handling in the client
80 library. Affected file lib/silcclient/client_notify.c. Also,
81 implemnted the printing of the SERVER_SIGNOFF info to the
82 application. Affected file silc/client_ops.c.
84 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
85 if the deleting was successful. Affected file silcd/idlist.[ch].
87 * Added support for public key authentication in the connection
88 authentication protocol in the client library. Affected file
89 lib/silcclient/protocol.c.
91 * Changed the server's silc_idlist_get_clients_by_* interface
92 to support already allocated array so that new entries may be
93 added to pre-allocated array. Affected file silcd/idlist.[ch].
94 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
97 * All command reply functions in the server now calls the
98 pending command callback even if error occured. This way the
99 error will be delivered to the client as well. Affected files
100 silcd/command.c and silcd/command_reply.c.
102 * Fixed INFO command to return local server's info if no server
103 was provided. Affected file lib/silcclient/command.c.
105 * Removed RESTART command for good. Updated the code and the
108 * Rewrote parts of the task system. It is a bit simpler now.
109 Removed unsued task priorities. The affected files are
110 lib/silcutil/silctask.[ch].
112 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
114 * Moved the USERS printing from the library to the application.
115 Affected files lib/silcclient/command.c and silc/client_ops.c.
117 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Added channel key re-key support. The re-key is perfomed
122 only by the router and is done once in an hour. Added `rekey'
123 field to the SilcChannelEntry in the server. Affected files
124 silcd/server.c and silcd/idlist.h.
126 * Added silc_task_unregister_by_context into the file
127 lib/silcutil/silctask.[ch].
129 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Added SILC_UMODE_GONE mode to indicate when the client is not
132 present in the SILC network. Added also support to the local
133 command AWAY that will set this mode. Added support of showing
134 "xxx is gone" in WHOIS command. The USERS command shows the
137 * Fixed setting server and router operator privileges in the
138 server's UMODE command. Affected file silcd/command.c.
140 * Merged the SKE KE1 and KE2 payloads into one payload. The
141 new KE payload is equivalent to the old KE2 payload.
143 Cleaned up the SKE Start Payload parsing. It now uses the
144 simple buffer unformatting to do the parsing. A lot faster
147 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
148 to the SKE that is used to indicate whether both of the SKE
149 parties should perform authentication. By default only the
150 responder performs authentication. By setting this flag also
151 the initiator must do authentication. By default it is unset
152 since in normal SKE case, client to server connection, only
153 the responder should do authentication. When doing SKE between
154 two clients both should perform authentication. Updated the
155 code and the protocol specs.
157 * A little fix to IDENTIFY command in the server. Search the
158 client first by hash not nickname. Affected file is
161 * Fixed the silc_client_close_connection to support closing
162 the client to client connections wihtout deleting too much
163 data. Affected file lib/silcclient/client.c.
165 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
166 are received if protocol used to be active but is not anymore
167 the application would crash due to NULL pointer dereference.
168 Affected files silcd/server.c and lib/silcclient/client.c.
170 * Added `hash' field to the SilcClientConnection to include
171 the hash function negotiated in the SKE protocol.
173 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
174 to set the channel founder authentication data. A client can
175 claim the founder rights later by providing the authentication
176 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
177 This way the channel founder can regain the channel founder
178 privileges even it is left the channel. This works only on
179 local server and the client must be connected to the same
180 server to be able to regain the founder rights. Updated the
181 protocol specs accordingly.
183 Added support to the CMODE command in the client to set the
184 founder auth data. Read the README to see how to set it.
186 Added support to the CUMODE command to claim the founder
187 rights. Read the README to see how to do it.
189 Added support for the founder authentication to the Channel
190 Entry in the server. Affected file silcd/idlist.h.
192 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
193 server's CMODE command. Affected file silcd/command.c.
195 * Added the following new functions into lib/silccore/silcauth.[ch]:
196 silc_auth_get_method and silc_auth_get_data.
198 * The server now saves the remote hosts public key to the
199 SilcIDListData pointer. Affected file silcd/protocol.c.
201 * The normal server now does not remove the channel entry from
202 the cache if the founder authentication data is set. It used
203 to remove it if the founder was the last one on the channel on
204 the server and left the channel. The auth data is saved and
205 if the channel is re-joined later the old entry is used with
206 the old auth data. Affected files silcd/command_reply.c and
209 * Removed the `pkcs' field from the SilcIDListData structure
210 in the server; it is not used. Affected file silcd/idlist.h.
212 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Fixed packet processing on slow links. Partial packets were
215 never re-processed because the incoming data buffer was cleared
216 by the application. Application must not directly clear the
217 sock->inbuf, the packet processing routines handle it. Fixed
218 this in client library and in server.
220 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Fixed the WHOIS and IDENTIFY send reply function to really
223 check whether to send list or just one entry. Affected file
226 * Cleaned up the LEAVE command's channel key distribution. The
227 affected file silcd/command.c.
229 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
230 can enforce the channel mode as well. In that case the ID
231 includes the ID of the server. The code now enforces the
232 mode change if the router have different mode than the server.
234 * The notify client operation with CMODE_CHANGE notify can now
235 return NULL client_entry pointer if the CMODE was not changed
236 by client. Application must check for this.
238 * Added <Server ID> argument to INFO command to support server
239 info fetching by Server ID.
241 * Added silc_server_announce_get_channel_users to get assembled
242 packets of channel users of the specified channel. Affected
243 file silcd/server.[ch].
245 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
246 was freed underneath the ID Cache.
248 * Re-announce clients when the server received CHANNEL_CHANGE
249 notify from the router. Affected file silcd/packet_send.c.
251 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
254 crashed since it did not handle the fact that there is no cipher
255 called "3" and didn't check the error condition. Now fixed.
257 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
258 flag. It can be used to send message requests.
260 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Implemented the RESTART command in the client.
264 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
265 notice type messages. Added notice printing to the user
268 * The channel keys are not re-generated if the channel's mode
269 is PRIVKEY, ie private key on the channel exists. Affected
270 files silcd/server.c and silcd/command.c.
272 * Fixed a little bug in channel message delivery when channel
273 private keys are set in the server. Affected file is
276 * Changed the setting on channel->on_channel = TRUE from the
277 silc_client_save_channel_key to the JOIN command reply. The
278 key payload is not received if the private channel key is set.
279 Affected file lib/silcclient/command_reply.c and the
280 lib/silcclient/client_channel.c.
282 * When the CMODE_CHANGE notify is sent and the channel private
283 key mode is removed the channel key must be re-generated in
284 other cells as well. Added this support for the router in the
285 silcd/packet_receive.c.
287 * Added new local command NOTICE to send notice message on
288 channel. Affected file silc/local_command.[ch].
290 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Added new local command ME to the client. It is used to send
293 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
294 some action. Affected file silc/local_command.[ch].
296 * Changed channel_message and private_message client operations
297 to deliver the message flags to the application. Added also
298 the `flags' arguments to the silc_client_send_channel_message
299 and silc_client_send_private_message functions. Affected file
302 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
304 * Redefined the Private Message Payload to support private message
305 keys and to support the new private message flags. Updated
306 the protocol specs. Flags makes it possible to have for example
309 * Added new type SilcPrivateMessagePayload and defined an API
310 for it in the lib/silcclient/silcprivate.[ch].
312 * Tested private message private keys successfully. Tested the
313 private message key set, unset and list commands with the new
316 * Redefined the Channel Message Payload to include the channel
317 message flags (equal with private message flags) to support
318 for example CTCP style messages.
320 * Defined some of the message (for channel and private message)
321 flags. Updated the protocol specs and added the flags to the
322 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
324 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Added SilcKeyAgreementStatus type to the key agreement routines
327 to indicate the current status and error if one occured.
328 The status types are defined in the lib/silcclient/silcapi.h.
330 * Added new local command KEY that is used to set and unset private
331 keys for channels, set and unset private keys for private messages
332 with remote clients and to send key agreement requests and
333 negotiate the key agreement protocol with remote client. The
334 key agreement is supported only to negotiate private message keys,
335 it currently cannot be used to negotiate private keys for channels,
336 as it is not convenient for that purpose.
338 * Fixed a minor pending callback setting bug in the function
339 silc_client_get_client_by_id_resolve, now the function works.
340 Affected file lib/silcclient/idlist.c.
342 * Added function silc_net_get_local_port to get local bound
343 port by socket. Added to lib/silcutil/silcnet.[ch].
345 * Added `sockets' and `sockets_count' fields to the SilcClient
346 object. They hold the sockets of the listenning sockets in
347 the client. Listenning sockets may be for example the key
348 agreement server. Affected file lib/silcclient/client.[ch].
349 Added functions the silc_client_add_socket and the
350 silc_client_del_socket. They are exported to the application
353 * Added ~./silc/clientkeys to support other client's public keys.
355 * Renamed verify_server_key client operation to verify_public_key
356 and added one argument to indicate the type of the connection
357 (server, client etc.).
359 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Added silc_server_connection_auth_request to handle the
362 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
363 silcd/packet_receive.[ch].
365 * Added silc_server_send_connection_auth_request into the
366 silcd/packet_send.c to send the connection auth request packet.
368 * Cleaned up the silcd/protocol.c a bit and fixed some memory
371 * Fixed the public key authentication in responder side in the
372 server. The `auth_data' pointer includes the SilcPublicKey
373 not the path to the public key. Affected file silcd/protocol.c.
375 * Implemented the public key authentication in the initiator side
376 in the server. Affected file silcd/protocol.c.
378 * Removed the [RedirectClient] config section from the server
379 configuration. Is not needed and I don't want to implement it.
381 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Cleaned up the CMODE command in the server. It now works
384 correctly and supports all the modes defined in the protocol.
385 Affected file is silcd/command.c.
387 * Added `hmac_name' field to the SilcChannelEntry in the server
388 to hold the default HMAC of the channel. It can be set when
389 creating the channel (with JOIN command). Affected files
392 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
393 type to indicate the change of the current cipher and hmac
394 on the channel. Client can safely ignore the <cipher> argument
395 (if it chooses to do so) since the CHANNEL_KEY packet will
396 force the channel key change anyway. The <hmac> argument is
397 important since the client is responsible of setting the new
398 HMAC and the hmac key into use.
400 * Fixed the CMODE command in the client library as well.
402 * Tested CMODE command in router environment successfully.
404 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Show the version of the remote client (or server) when connecting
407 to the server. It is logged to the log file. Affected file
410 * Fixed the KILLED notify handling in the client library. The
411 client must be removed from all channels when receiving the
414 Also, do not remove the client entry when giving the KILL
415 command but when the KILLED notify is received.
417 * Removed silc_idlist_find_client_by_nickname from the server.
418 Not needed anymore. Affected files silcd/idlist.[ch].
420 * Implemented the CHANNEL_CHANGE notify type handling to the
421 server. Affected file silcd/server.c.
425 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Added silc_server_send_notify_invite to send the INVITE
428 notify between routers.
430 * Implemented the INVITE command correctly to the server.
432 * Implemented the INVITE notify type handling in the server.
434 * Implemented the INVITE command to the client library and on the
437 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Added function silc_server_get_client_resolve to find the
440 client entry by ID from all ID lists and then resolve it
441 (using WHOIS) if it cannot be found. Affected file is
444 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
446 * Implemented the BAN command to the client library.
448 * The JOIN command in the server now checks the invite list
451 * Changed the silc_command_reply_payload_encode_va and the
452 silc_command_payload_encode_va to support that if argument is
453 NULL it ignores and checks the next argument. Affected file
454 lib/silccore/silccommand.c.
456 * Added silc_server_send_notify_ban to send the BAN notify
457 type between routers.
459 * Chaned the silc_notify_payload_encode to support that if
460 argument is NULL it ignores and checks the next argument.
461 Affected file lib/silccore/silcnotify.c.
463 * Tested ban lists in router environment successfully.
465 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * Implemented BAN command to the server, in silcd/command.[ch].
469 * Removed the BAN and INVITE_LIST modes from the CMODE command
472 * Added function silc_string_match to regex match two strings.
473 Affected files lib/silcutil/silcutil.[ch].
475 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
477 * Redefined parts of the SilcChannelEntry in the server to support
478 the new ban and invite lists.
480 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
482 * Redefined the INVITE command. The same command can be used to
483 invite individuals to the channel but also to manage the invite
484 list of the channel (to add to and remove from the invite list).
485 Updated the protocol specs.
487 * Added new command SILC_COMMAND_BAN that can be used to manage
488 the ban list of the channel. Updated the protocol specs.
490 * Removed the channel modes: the SILC_CMODE_BAN and the
491 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
492 in the CMODE command. The equivalent features are now available
493 using INVITE and BAN commands. Updated the protocol specs.
495 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
496 in the network about change in the current ban list. The notify
497 type is not used by the client.
499 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
500 support the invite lists.
502 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Added new function silc_string_regexify that converts string
505 including wildcard characters into regex string that can
506 be used by the GNU regex library. Added into the file
507 lib/silcutil/silcutil.[ch].
509 Added silc_string_regex_combine to combine to regex strings
510 into one so that they can be used as one regex string by
511 the GNU regex library. Added into the file
512 lib/silcutil/silcutil.[ch].
514 Added silc_string_regex_match to match two strings. It returns
515 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
517 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Imported GNU regex to the soruce tree into lib/contrib.
520 Fixed some compiler warning from the regex.c.
522 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Fixed MOTD command in the server to work in router environment.
526 * Fixed the MOTD command in the client library to support
527 the server argument in the command.
529 * Added `nickname_len' argument to the silc_idlist_add_client
530 in the server, as the `nickname' argument may be binary data
533 * Added silc_idlist_get_channels to return all channels from
536 * Implemented LIST command to the server. Affected file is
539 * Implemented the LIST command to the client library and on the
542 * Added [<user count>] argument to the LIST command reply.
543 With private channels the user count is not shown.
545 * Updated TODO and README.
547 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * The client entry's data.registered must be TRUE even with
550 global client entry on global client list. The data.registered
551 is used to check whether the client is anymore in the network,
552 for example with WHOWAS command so it must be valid.
554 * Fixed the WHOWAS command in the server. It now actually works
555 in router environment. Added function into silcd/command_reply.c
556 silc_server_command_reply_whowas_save.
558 * Added silc_idlist_purge function to the silcd/idlist.c
559 to periodically purge the ID Cache.

568 * Fixed various bugs in WHOIS and IDENTIFY command handling as
569 they were buggy because of the WHOWAS information.
571 * Fixed local command MSG to handle the async resolving of
572 the remote client properly. It used to fail the first MSG.
573 Affected file silc/local_command.c.
575 * Added `data_len' field to SilcIDCache context.
577 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Update TODO. Todo in commands in the server.
581 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
584 used by routers as broadcast packet to inform other routers
585 about the changed user mode.

588 silcd/packet_receive.c. Added the function
589 silc_server_send_notify_umode to the silcd/packet_send.[ch].
591 * Added new generic Channel Payload and deprecated the New Channel
592 Payload. The New Channel Payload is now the generic Channel
595 * Added new argument `mode' to the silc_server_send_new_channel
596 as it is required in the Channel Payload now.
598 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
599 and created a new and real SilChannelPayload to represent the
600 new generic Channel Payload. Implemented the encode/decode
601 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
603 * Added silc_server_get_client_channel_list to return the list
604 of channels the client has joined for WHOIS command reply.
605 Affected file silcd/server.[ch].
607 * Implemented the channel list sending in the WHOIS command reply
608 in server and in the client.
610 Implemented the channel list displaying on the user interface
611 as well. Affected file silc/client_ops.c.
613 * Added silc_channel_payload_parse_list to parse list of Channel
614 Payloads. It returns SilcDList list of SilcChannelPayloads.
615 Client for example can use this function to parse the list of
616 channels it receives in the WHOIS command reply. The caller
617 must free the list by calling silc_channel_payload_list_free.
618 Affected files lib/silccore/silcchannel.[ch].
620 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Added one new argument <user mode> to the WHOIS command reply
623 to return the mode of the user in SILC. Updated the protocol
626 Implemented it to the server and client.
628 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Fixed the mode printing on the user interface on joining.
631 Affected file silc/client_ops.c.
633 * Implemented the UMODE command and user modes in general to the
634 client library and to the user interface.
636 * Implemented the UMODE command to the server.
638 * The server now sends UNKNOWN_COMMAND error status if client sends
639 unknown command. Affected file silcd/command.c.
641 * All server commands now handle the command identifier the right
642 way when sending the command reply to the client. The client can
643 use to identify the command replies with the identifier.
645 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Added silc_server_get_client_route to resolve the route to
648 the client indicated by the client ID. Affected file is
651 * Added silc_server_relay_packet as general function to relay
652 packet to arbitrary destination. This deprecates functions
653 like _send_private_message_key, _relay_notify etc. Affected
654 file is silcd/packet_send.[ch].
656 Removed silc_server_send_key_agreement,
657 silc_server_send_private_message_key and
658 silc_server_packet_relay_notify functions from the file
659 silcd/packet_send.[ch].
663 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
664 server. Affected file silcd/packet_receive.[ch].
666 * Implemented the KILL command to the client. Implemented the
667 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
668 Affected files lib/silcclient/command[_reply].c and
669 lib/silcclient/client_notify.c. Implemented the KILL notify
670 printing in the user inteface.
672 * Fixed a lot silc_parse_nick memory leaks from the client
673 library in the file lib/silcclient/command.c.
675 * Changed the silc_server_send_notify_on_channels's `sender'
676 argument from SilcSocketConnection to SilcClientEntry to
677 check the sender as entry and not as connection object and not
678 to send to the client provided as argument. The affected file
679 is silcd/packet_send.[ch].
681 * The notify packets that are destined directly to the client used
682 to not to be processed by the server. Now changed that and the
683 server processes all notify packets. After relaying the packet
684 to the client the notify packet is processed in the server.
686 * The silc_server_free_client_data now checks whether there is
687 pending outgoing traffic for the client and purges the data to
688 the network before removing the client entry.
690 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
693 an client is killed from the SILC Network. Updated the protocol
696 Added new function silc_server_send_notify_killed to the
697 silcd/packet_send.[ch].
699 * Added function silc_server_packet_relay_notify to relay notify
700 packets that are destined directly to a client. In this case
701 the server does not process the notify packets but merely relays
702 it to the client. Affected file silcd/packet_send.[ch].
704 Added also silc_server_packet_process_relay_notify to check
705 whereto relay the notify. Affected file is
706 silcd/packet_receive.[ch].
708 * Implemented the KILL command to the server.
712 * Added the backup schema desgined last fall to the protocol
713 specs for everyone to see. The specification is in the
714 *-spec-xx.txt draft and the packet type definitions for the
715 backup routers is in *-pp-xx.txt draft. Thusly, added also
716 new packet type SILC_PACKET_CELL_ROUTERS.
718 * A big security problem in the implementation discovered. The
719 signoff of an client did not cause new channel key generation
720 which it of course should've done. The channel keys must be
721 always re-generated when client leaves (or signoffs) the channel.
722 The silc_server_remove_from_channels funtion now handles
723 the channel key re-generation.
725 * Added `sender' argument to the silc_server_send_notify_on_channels
726 to not to send the client provided as argument. Affected file
727 silcd/packet_send.[ch].
729 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Implemented OPER and SILCOPER commands into the server and
734 * Added silc_auth_verify and silc_auth_verify_data to verify
735 the authentication directly from the authentication payload.
736 It supports verifying both passphrase and public key based
737 authentication. Affected file lib/silccore/silcauth.[ch].
739 * Added `hash' field to the SilcIDListData structure. It is the
740 hash negotiated in the SKE protocol. Affected file is
743 * Slight redesigning of the SilcAuthPayload handling routines.
744 Do not send SilcPKCS but SilcPublicKey as argument.
746 * Implemented the public key authentication support to the
747 serverconfig. The public key is loaded from the provided path
748 and saved as authentication data to void * pointer. Thus,
749 changed the unsigned char *auth_data to void *auth_data;
751 * Fixed SHUTDOWN command to send the reply before the server
752 is shutdown. :) Affected file silcd/command.c.
754 * Fixed fatal bug in CONNECT command. The hostname was invalid
755 memory and server crashed. Affected file silcd/command.c.
757 * Fixed fatal bug in CLOSE command. The server_entry became
758 invalid but was referenced later in the command. Affected file
761 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * Fixed fatal bug in failure packet handling. Server ignored
764 the failure and thus crashed when it came.
768 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
771 that the command may be executed only once in (about) 2 seconds.
772 The old SILC_CF_LAG flag is same but allows command bursts up
773 to five before limiting.
775 Added the support for CF_LAG and CF_LAG_STRICT flags to the
776 server code. Various commands now includes the CF_LAG_STRICT
777 flag to disallow any kind of miss-use of the command.
779 * Fixed the silc_buffer_unformat to not to allocate any data
780 if the length of the data is zero. It used to allocate the
781 length + 1. Affected file lib/silcutil/silcbuffmt.c.
783 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Changed the format of AdminConnection configuration section
786 in the server. Added username of the admin to the format.
787 Affected files silcd/serverconfig.[ch].
789 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
790 to return admin configuration data by host, username and/or
793 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Implemented WHOWAS command to the server. Added the functions:
797 silc_server_command_whowas_parse,
798 silc_server_command_whowas_send_reply,
799 silc_server_command_whowas_from_client and
800 silc_server_command_whowas_from_server
802 * Added <Client ID> argument to the WHOWAS command reply. Updated
803 the protocol specs accordingly.
805 * Implemented WHOWAS command and command_reply to the client
808 Implemented the WHOWAS printing on the user interface.
810 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Added new argument to the WHOWAS command reply, the real name.
813 It is an optional argument. Updated the protocol specs.
815 * Added SilcIDCacheDestructor callback that is registered when
816 the SilcIDCache is allocated. The callback is called when
817 an cache entry in the ID Cache expires, or is purged from the
818 cache. Added into lib/silccore/idcache.[ch].
820 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
821 to destruct the client entries when the cache entry expires.
822 Other ID Cache's in server and in the client library ignores
825 * If the ID Cache entry's `expire' field is zero then the entry
826 never expires. Added boolean `expire' argument to the
827 silc_idcache_add function in the lib/silccore/idcache.[ch].
828 If it is TRUE the default expiry value is used.
830 * Added silc_server_free_client_data_timeout that is registered
831 when client disconnects. By default for 5 minutes we preserve
832 the client entry for history - for WHOWAS command.
834 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added support to the server to enforce that commands are not
837 executed more than once in 2 seconds. If server receives
838 commands from client more frequently, timeout is registered
839 to process the commands. Affected file silcd/command.c.
840 Added new function silc_server_command_process_timeout.
842 * Changed NICK_NOTIFY handling in client library to check that
843 if the client's nickname was changed, so there is no need to
844 resolve anything from the server.
846 * Removed error printing from the WHOIS and IDENTIFY commands.
847 If error occurs then it is ignored silently in the client library.
848 The application, however, may map the received error to
849 human readable error string. The application currently maps
850 the NO_SUCH_NICKNAME error to string.
852 * Made the command status message public to the application. Moved
853 them from lib/silcclient/command_reply.c to
854 lib/silcclient/command_reply.h. The application can map the
855 received command status to the string with the
856 silc_client_command_status_message function.
858 * Added check to the server to check that client's ID is same
859 as the Source ID in the packet the client sent. They must
862 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Added dist-bzip hook to the Makefile.am to make bzip2
865 compressed distributions.
867 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Server now enforces the maximum length for the nickname and
870 the channel as protocol specification dictates. 128 bytes for
871 nickname and 256 bytes for channel name.
873 * Moved the WHOIS printing to the application. The client libary
874 does not print out the WHOIS information anymore, the application
875 must do it. Renamed silc_client_command_reply_whois_print to
876 the silc_client_command_reply_whois_save.
878 The client's idle time is also sent to the application now, and
879 the idle is shown on screen.
881 * Added silc_client_command_reply_identify_save to save the
882 received IDENTIFY entries.
884 * Do not check for channel private keys in message sending and
885 reception if the channel does not have the PRIVKEY mode set.
886 Affected file lib/silclient/client_channel.c.
888 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
891 just surfaced after chaning the JOIN procedure.
893 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Added silc_client_get_clients_by_list to get client entries
896 from Client ID list, that is returned for example by JOIN
897 and USERS command replies. The application should use this
898 function for example when JOIN command reply is received to
899 resolve the clients already on the channel (library does not
900 do that anymore as USERS command reply is not used in the JOIN
901 procedure anymore). Affected files lib/silcclient/silcapi.h and
902 lib/silcclient/idlist.c.
904 * JOIN command reply and USERS command reply returns now SilcBuffer
905 pointers instead of unsigned char pointers when returning
906 the client list and mode list.
908 * Added <Client ID> argument to the JOIN command reply, mainly
909 for the server to identify for which client the command was
910 originally sent. Updated protocol specs accordingly.
912 * Added SilcDlist private_key pointer to the SilcChannelEntry
913 in the client to support the channel private keys. Affected
914 file is lib/silcclient/idlist.h.
916 * Added SilcChannelPrivateKey argument to the function
917 silc_client_send_channel_message so that application can choose
918 to use specific private ke if it wants to. If it is not provided,
919 the normal channel key is used, unless private keys are set.
920 In this case the first (key that was added first) is used
921 as the encryption key.
923 * Implemented the support for channel private key handling.
924 Implemented the following functions:
926 silc_client_add_channel_private_key,
927 silc_client_del_channel_private_keys,
928 silc_client_del_channel_private_key,
929 silc_client_list_channel_private_keys and
930 silc_client_free_channel_private_keys
932 Affected file lib/silcclient/client_channel.c.
934 * Added the support for the private keys in the channel message
935 sending and encryption and in the message reception and
936 decryption. Affected funtions are
937 silc_client_send_channel_message and silc_client_channel_message.
939 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Added SKE's key verify callback to the client library's
942 KE protocol context. Affected files lib/silcclient/protocol.[ch].
944 * Removed the statement that server (or router) must send USERS
945 command reply when joining to the channel so that the client
946 knows who are on the channel. Instead, the client list and
947 client's mode list is now sent in the JOIN command reply to the
948 client who joined channel. This is better solution.
950 * Added function silc_server_get_users_on_channel and function
951 silc_server_save_users_on_channel to the silcd/server.[ch].
953 * Removed function silc_server_command_send_users from the
956 * Do not show topic on the client library anymore. The topic is
957 sent in the command reply notify to the application and the
958 application must show the topic now.
960 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Added client searching by nickname hash into the IDENTIFY and
963 WHOIS commands in the server as they were clearly missing from
964 them. Affected file is silcd/command.c.
966 * Fixed a bug in private message receiving in the client library.
967 The remote ID was freed and it wasn't supposed, now it is
970 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Minor fix to the channel payload; allocate the data area, as it
973 needs to be of specific length.
975 * If the key agreement port is zero then the operating
976 system will define the bound port. Affected files are
977 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
979 * Added new function silc_channel_payload_decrypt into the file
980 lib/silccore/silcchannel.[ch].
982 * Moved the channel message etc, check from silc_packet_decrypt
983 to applications. The library calls now a generic
984 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
985 when the packet is either normal or special. This was done to
986 allow more wide range of checking that was not allowed when
987 the code was in library. Now applications can do virtually any
988 checks to the packet and return to the library the decision how
989 the packet should be processed. Affected files are
990 lib/silccore/silcpacket.[ch].
992 Added silc_server_packet_decrypt_check to the server and
993 silc_client_packet_decrypt_check to the client library.
995 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
996 to send with specified source and destination information.
998 * Channel message delivery between routers was broken after the
999 channel key distribution was fixed earlier. The channel key
1000 was used be to distributed to other routers as well which is not
1001 allowed by the protocol. Now this is fixed and channel keys
1002 really are cell specific and the channel message delivery between
1003 routers comply with the protocol specification.
1005 * Fixed various commands in server to check also the global list
1006 for the channel entry and not just the local list. The affected
1007 file silcd/command.c.
1009 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Added assert()s to buffer formatting and unformatting routines
1012 to assert (if --enable-debug) when error occurs. Affected
1013 file: lib/silcutil/silcbuffmt.c.
1015 * Changed to auto-reconnect to check whether the remote host is
1016 router and register the re-connect timeout if it is. It used
1017 to check that whether we are normal server, but router must do
1018 auto-reconnect with another router as well. Affected file
1021 * Removed the [<key len>] option from CMODE command as the cipher
1022 name decides the key length, nowadays. See the defined ciphers
1023 from the protocol specification.
1025 * Added [<hmac>] option to the CMODE command to define the HMAC
1026 for the channel. Added SILC_CMODE_HMAC channel mode.
1028 * Added [<hmac>] option for the JOIN command so that user can
1029 select which HMAC is used to compute the MACs of the channel
1032 * Added Hmac field to the Channel Message Payload. The integrity
1033 of plaintext channel messages are now protected by computing
1034 MAC of the message and attaching the MAC to the payload. The
1035 MAC is encrypted. Now, it is clear that this causes some
1036 overhead to the size of the packet but rationale for this is that
1037 now the receiver can verify whether the channel message decrypted
1038 correctly and also when private keys are set for the channel the
1039 receiver can decrypt the packet with several keys and check from
1040 the MAC which key decrypted the message correctly.
1042 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1043 lib/silccrypt/silccipher.[ch].
1045 * Added silc_hash_len to return the digest length into the
1046 lib/silcrypt/silchash.[ch].
1048 * Rewrote parts of Silc Channel Payload interface in the
1049 lib/silccore/silcchannel.[ch]. The encode function now also
1050 encrypts the packet and parse function decrypts it.
1052 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Fixed a minor formatting bug in the SKE's key material processing.
1055 It actually might have processed the keys wrong way resulting
1058 * Redefined the mandatory HMAC algorithms and added new algorithms.
1059 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1060 and hmac-md5 truncated to 96 bits. The mandatory is now
1061 hmac-sha1-96. Rest are optional (including the one that used
1062 to be mandatory). Rationale for this is that the truncated HMAC
1063 length is sufficient from security point of view and can actually
1064 make the attack against the HMAC harder. Also, the truncated
1065 HMAC causes less overhead to the packets. See the RFC2104 for
1068 * Added new [hmac] configuration section. The SKE used to use
1069 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1070 is of course wrong. The official names that must be proposed in
1071 the SKE are the ones defined in the protocol specification
1072 (hmac-sha1-96 for example). The user can configure any hmac
1073 using any hash function configured in the [hash] section. At
1074 least, the mandatory must be configured.
1076 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1078 * Added HMAC list to the SKE proposal list. It has now both
1079 hash algorithm list and HMAC list. This makes the protocol
1080 incompatible with previous versions. The SKE now seems to work
1081 the way it is supposed to work, for the first time actually.
1083 * Defined plain Hash algorithms to the protocol specification.
1086 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Implemented support for key agreement packets into the server.
1089 Added functions silc_server_key_agreement and
1090 silc_server_send_key_agreement. Other than these functions,
1091 server has nothing to do with this packet.
1093 * Added support for private message key packets into the server.
1094 Added functions silc_server_private_message_key and
1095 silc_server_send_private_message_key.
1099 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1100 called in the protocol's final callback instead in the END
1101 protocol state. This makes a little more sense and in the same
1102 time in client we can use the same protocol routines for normal
1103 key exchange and to key agreement packet handling as well.
1105 * Added to both client's and server's KE protocol context the
1106 SilcSKEKeyMaterial pointer to save the key material. We will
1107 bring the key material to the protocol's final callback by doing
1108 this. The final callback must free the key material.
1110 * Added SKE's packet_send callback into client's KE protocol
1111 context so that the caller can choose what packet sending function
1112 is used. This way we can use different packet sending when
1113 doing normal SKE when doing key agreement packet handling (in
1114 the key agreement packet handling we do not want to encrypt
1117 * Implemented the responder side of the key agreement routines
1118 in the client. The client can now bind to specified port and
1119 accept incoming key negotiation. The key material is passed
1120 to the application after the protocol is over.
1122 * Implemented the processing of incoming Key Agreement packet
1123 in the client. Added function silc_client_key_agreement to
1126 * Implemented the intiator side of the key agreement routines
1127 in the client. The client can now initiate key agreement with
1128 another remote client. The key material is passed to the
1129 application after the protocol is over.
1131 * Created client_keyagr.c to include all the key agreement
1134 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1135 SILC_TASK_CALLBACK except that it is not static.
1137 * Created client_notify.c and moved the Notify packet handling
1138 from the client.[ch] into that file.
1140 * Created client_prvmsg.c and moved all private message and
1141 private message key routines from the client.[ch] into that file.
1143 * Create client_channel.c and moved all channel message and
1144 channel private key routines from the client.[ch] into that file.
1146 * Changed silc_client_get_client_by_id_resolve to resolve with
1147 WHOIS command instead of IDENTIFY command, in the file
1148 lib/silclient/idlist.c.
1150 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Implemented the SKE's responder side to the Client library.
1154 * When FAILURE is received to the protocol do not trust it
1155 blindly. Register a timeout to wait whether the remote closes
1156 the connection as it should do it, only after that process the
1157 actual failure. This was changed to both client and server.
1159 * Added client_internal.h to include some of the structures
1160 there instead of client.h in lib/silcclient/.
1162 * Added function silc_task_unregister_by_callback to unregister
1163 timeouts by the callback function.
1165 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Some "Incomplete WHOIS info" errors has been appearing on the
1168 log files. Took away the entry->userinfo check from WHOIS
1169 reply sending. The entry->userinfo is now " " if client did not
1170 provide one. I thought this was fixed earlier but something
1171 is wrong still. Let's see if the error still appears.
1173 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Fixed a minor bug in the login when the channel key is
1176 re-generated in the server. It used to generate the key in
1177 wrong order and thus caused problems in the channel traffic.
1179 * Fixed a minor bug in channel key distsribution after
1180 KICK command. The key was not sent to the router even though
1183 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Added silc_ske_process_key_material_data as generic routine
1186 to process any key material as the SILC protocol dictates. The
1187 function is used by the actual SKE library but can be used by
1188 applications as well. This relates to the private message keys
1189 and the channel private keys since they must be processed the
1190 same way the normal SILC session keys. The protocol dictates
1191 this. Affected files: lib/silcske/silcske.[ch].
1193 Added also silc_ske_free_key_material to free the
1194 SilcSKEKeyMaterial structure.
1196 * Defined silc_cipher_set_key function to set the key for
1197 cipher without using the object's method function. The affected
1198 files: lib/silccrypt/silccipher.[ch].
1200 * Implemented silc silc_client_add_private_message_key,
1201 silc_client_add_private_message_key_ske,
1202 silc_client_del_private_message_key,
1203 silc_client_list_private_message_keys and
1204 silc_client_free_private_message_keys functions in the
1207 Added functions silc_client_send_private_message_key to send
1208 the Private Message Key payload and silc_client_private_message_key
1209 to handle incoming Private Message Key payload.
1211 * Added Cipher field to the Private Message Key payload to set
1212 the cipher to be used. If ignored, the default cipher defined
1213 in the SILC protocol (aes-256-cbc) is used.
1215 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * Removed lib/silcclient/ops.h file.
1219 Redefined parts of the SILC Client Library API. Created new
1220 file silcapi.h that deprecates the ops.h file and defines the
1221 published Client Library API. Defined also private message key
1222 API and channel private key API into the file.
1224 This is the file that the application must include from the
1225 SILC Client Library. Other files need not be included by
1226 the application anymore.
1228 * Added new key_agreement client operation callback and also
1229 defined the Key Agreement library API for the application.
1231 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1233 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1234 is used by clients to request key negotiation between another
1235 client in the SILC network. If the negotiation is started it
1236 is performed using the SKE protocol. The result of the
1237 negotiation, the secret key material, can be used for example
1238 as private message key.
1240 Implemented the Key Agreement payload into the files
1241 lib/silccore/silauth.[ch].
1243 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Redefined ciphers for the SILC protocol. Added some new ciphers
1246 and defined the key lengths for the algorithms. Changed the
1247 code accordingly. The default key length is now 256 bits.
1249 * Fixed SKE key distribution function silc_ske_process_key_material
1250 when the key length is more than 128 bits. The default key
1251 length in SILC is now 256 bits.
1253 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1254 to indicate unsupported algorithm.
1256 * Renamed rijndael.c to aes.c and all functions as well.
1258 * Fixed a long standing channel key setting bug in client library.
1259 Weird that it has never surfaced before.
1261 * Fixed bug in channel deletion. If the entire channel is removed
1262 then it must also delete the references of the channel entry
1263 from the client's channel list as the client's channel entry and
1264 the channel's client entry share same memory.
1266 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Implemented CONNECT and SHUTDOWN commands in the client.
1270 * Implemented CLOSE command to the client.
1272 * Added the function silc_idlist_find_server_by_name into the
1273 files silcd/idlist.[ch].
1275 Added the function silc_idlist_find_server_by_conn into the
1276 files silcd/idlist.[ch].
1278 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * DIE command was renamed to SHUTDOWN. Updated the both code
1283 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1284 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1286 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1289 * Added function silc_server_create_connection function to create
1290 connection to remote router. My server implementation actually
1291 does not allow router to connect to normal server (it expects
1292 that normal server always initiates the connection to the router)
1293 so the CONNECT command is only good for connecting to another
1296 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1299 or some other client was kicked from the channel.
1301 Implemented the handling of the notify type to both client
1304 Implemented silc_server_send_notify_kicked to send the KICKED
1305 notify. It is used to send it to the server's primary router.
1307 * Implemented the KICK command into server and client.
1309 * Added `query' argument to the silc_idlist_get_client function
1310 to indicate whether to query the client from server or not if
1313 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1314 to indicate that the client is not channel founder.
1318 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Removed the rng context from SilcPacketContext structure and
1321 changed that the packet routine uses the Global RNG API.
1323 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1325 * Added support for quit message that client can "leave" on the
1326 channel when it quits the SILC. It is ditributed inside the
1327 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1329 Added silc_server_free_client_data that will take the
1330 signoff message as argument.
1332 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1334 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Updated parts of the protocol specification to keep it up
1339 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1342 payloads in one packet.
1344 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1345 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1346 use now the new List flag.
1348 * Also deprecated the following packet types: REPLACE_ID,
1349 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1351 * Added list support for Notify packet in server.
1353 * Added silc_server_send_notify_channel_change to send the
1354 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1355 the silc_server_send_replace_id.
1357 * Added silc_server_send_notify_nick_change to send the
1358 NICK_CHANGE notify type. Deprecates the function
1359 silc_server_send_replace_id.
1361 * Added silc_server_send_notify_join to send the JOIN notify type.
1362 Deprecates the function silc_server_send_new_channel_user.
1364 * Added silc_server_send_notify_leave to send LEAVE notify type.
1365 Deprecates the function silc_server_send_remove_channel_user.
1367 * Added silc_server_send_notify_cmode and
1368 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1369 types. Deprecates the silc_server_send_set_mode function.
1371 * Added SERVER_SIGNOFF notify type to indicate that server has
1372 quit. This means that all clients on the channel from that
1373 server will drop. This can be also used when netsplit happens.
1375 Deprecated REMOVE_ID packet type since it is not needed anymore
1378 Added silc_server_send_notify_server_signoff to send the
1379 SERVER_SIGNOFF notify type. Deprecates the function
1380 silc_server_send_remove_id.
1382 Added also silc_server_send_notify_signoff to send the
1383 SIGNOFF notify type.
1385 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1386 SILC protocol from this day on. Changed the protocol
1387 specification as well.
1389 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1390 notify type. It is used between routers to notify about
1391 topic changes on a channel.
1393 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1396 * Partly updated the protocol specification to comply with the
1397 changes now made. It is still though a bit outdated.
1399 * The JOIN notify type now takes one extra argument <Channel ID>.
1400 The packet used to be destined to the channel but now the
1401 JOIN type may be sent as list thus it is impossible to
1402 destine it to any specific channel. By adding this argument
1403 it is again possible.
1405 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Added CREDITS file. The CHANGES and CREDITS file will appear
1408 in the distribution as well.
1410 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1413 types in the server's silcd/packet_receive.c.
1415 * Implemented CMODE and CUMODE to work in router environment.
1417 * Fixed minor encoding and decoding buglet from the
1418 lib/silccore/silcmode.c.
1420 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1423 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1425 * Changed all SilcConfigServer* and silc_config_server* to
1426 SilcServerConfig* and silc_server_config*, respectively.
1429 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Associated the ID (client or server ID) to the Authentication
1432 Payload to avoid any possibility of forging. Updated the
1433 protocol specification and the code accordingly.
1435 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * The RSA key length is now save to the RsaKey context in the
1438 key generation process in lib/silccrypt/rsa.c. The key length
1439 is now used to figure out the maximum size of the block allowed
1440 to be encrypted/signed.
1442 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1443 is equivalent to the silc_mp_mp2bin but does not allocate any
1446 * Changed silc_mp_mp2bin API to take length argument. If it is
1447 non-zero then the buffer is allocated that large. If zero, then
1448 the size is approximated using silc_mp_sizeinbase, which however
1451 * Created Global RNG API which is global RNG that application can
1452 initialize. After initializing, any routine anywhere in the
1453 code (including library) can use RNG without allocating a new
1454 RNG object. This was done to allow this sort of use of the
1455 RNG in code that has no chance to allocate RNG object. All
1456 applications currently allocate this and many routines in the
1457 library use this. Affected file lib/silccrypt/silcrng.[ch].
1459 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1460 it to use the Global RNG API.
1462 * Defined Authentication Payload into protocol specification that
1463 is used during SILC session to authenticate entities. It is
1464 used for example by client to authenticate itself to the server
1465 to obtain server operator privileges.
1467 Implemented this payload into the lib/silccore/silcauth.[ch].
1468 Implemented also routines for public key based authentication
1469 as the new protocol specification dictates.
1471 Moved definitions of different authentication methods from
1472 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1474 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1475 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1476 silc_pkcs_verify_with_hash functions into the file
1477 lib/silccrypt/silcpkcs.[ch].
1479 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * The client entry's userinfo pointer must be always valid.
1482 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1483 will fail since it requires the userinfo. Now, the userinfo
1484 is allocated as "" if actual userinfo does not exist. Actually,
1485 it must exist and it is totally Ok to drop client connections
1486 that does not announce the userinfo. However, we will make
1487 this workaround for now.
1489 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1490 to return the remote port by socket.
1492 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1495 SILC_SERVER_PENDING_EXEC and added an new macro
1496 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1497 data or when error occurs while processing the pending command.
1499 Added new argument `destructor' into silc_server_command_pending
1500 and to the SilcServerCommandPending object. This destructor is
1501 now called after calling the pending callback or if error occurs
1502 immediately. If error occurs the actual pending callback won't
1503 be called at all - only the destructor. The destructor may be
1504 NULL if destructor is not needed.
1506 All this applies for client library code as well. Similar
1507 changes were made there as well for the pending commands.
1509 In the client, the application must now allocate the
1510 SilcClientCommandContext with the silc_client_command_alloc
1513 * Added reference counter to the SilcServerCommandContext. Added
1514 function silc_server_command_alloc and silc_server_command_dup
1517 Same type of functions added to the client library for the same
1520 * Removed the cmd_ident from IDListData away since it is now
1521 global for all connections. It is the command identifier used
1522 in command sending and with pending commands. The affected file
1525 * Added reference counter to the SilcSocketConnection objecet to
1526 indicate the usage count of the object. The object won't be
1527 freed untill the reference counter hits zero. Currently only
1528 server uses this, and client ignores it. The client must be
1529 set to use this too later. The affected files are
1530 lib/silccore/silcsockconn.[ch]. Added also the function
1531 silc_socket_dup to increase the reference counter.
1533 This was mainly added because it is possible that the socket
1534 is removed underneath of pending command or other async
1535 operation. Now it won't be free'd and proper DISCONNECTING
1536 flags, etc. can be set to avoid sending data to connection that
1537 is not valid anymore.
1539 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1540 the connection. After that it sets SILC_SET_DISCONNECTED.
1541 It is, however, possible that the socket data is not still freed.
1542 The silc_server_packet_process now checks that data is not
1543 read or written to connection that is DISCONNECTED. The socket
1544 get's freed when the reference counter hits zero.
1546 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1548 * Changed the client operation API: channel_message operation's
1549 `sender' is now the client entry of the sender, not the nickname
1550 and the `channel' is the channel entry, not the channel name.
1552 In the private_message operation the `sender' is now also the
1553 client entry of the sender not the nickname.
1555 Affected file is lib/silcclient/ops.h and all applications
1556 using the client operations.
1558 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Moved the calling of ops->connect() from connect_to_server_final
1561 into receive_new_id functin since that is the point when the
1562 client is actually allowed to send traffic to network. The
1563 affected file is lib/silcclient/client.c.
1565 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1568 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1569 (if needs broadcasting) instead of broadcasting the packets one
1570 by one which would make a burst in the network traffic.
1572 * Added `broadcast' argument to the functions in silcd/server.[ch]
1573 silc_server_create_new_channel[_with_id] to indicate whether
1574 to send New Channel packet to primary router.
1576 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added new function into the silcd/server.[ch] files:
1579 silc_server_create_new_channel_with_id to create new channel with
1580 already existing Channel ID.
1582 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1583 lib/silccore/silcpacket.h. This packet is used t send list of
1584 Set Mode payloads inside one packet. Server uses this to set
1585 the modes for the channels and clients on those channels, that it
1586 announced to the router when it connected to it. The protocol
1587 specification has been updated accordingly.
1589 * The silc_server_new_channel did not handle the packet coming
1590 from normal server as it normally does not send that. However,
1591 when it announces its channels it does send it. Implemented
1592 the support for that.
1594 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1595 into the file lib/silccore/id.h.
1597 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Fixed memory leaks in the functions silc_idlist_del_client,
1600 silc_idlist_del_channel and silc_idlist_del_server in the file
1601 silcd/idlist.c. All of those leaked like a sieve.
1603 * Fixed some small memory leaks in the client's function
1604 silc_client_notify_by_server.
1606 * Added functions into silcd/server.c: silc_server_announce_clients,
1607 silc_server_announce_channels and silc_server_announce_server.
1608 These functions are used by normal and router server to announce
1609 to its primary router about clients, channels and servers (when
1610 router) that we own. This is done after we've connected to the
1613 These functions effectively implements the following packet types:
1614 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1615 and SILC_PACKET_NEW_ID_LIST.
1617 * Added new functions into the silcd/packet_receive.[ch]:
1618 silc_server_new_id_list, silc_server_new_channel_list and
1619 silc_server_new_channel_user_list to handle the incoming
1620 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1622 * Added support of changing Channel ID in the function
1623 silc_server_replace_id. If the server that announces a channel
1624 to the router already exists in the router (with same name but
1625 with different Channel ID), router is responsible to send
1626 Replace ID packet to the server and force the server to change
1627 the Channel ID to the one router has.
1629 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1630 client that the Channel ID has been changed by the router. The
1631 normal server sends this to the client. Client must start using
1632 the new Channel ID as the channel's ID.
1634 Implemented handling of this new type into lib/silcclient/client.c
1635 into the function silc_client_notify_by_server.
1637 * Added new function silc_idlist_replace_channel_id into the files
1638 silcd/idlist.[ch] to replace the Channel ID.
1640 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Call silc_server_command_identify_check always when processing
1643 the IDENTIFY command in silcd/command.c
1645 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1648 send keepalive packets. The packet can be sent by clients,
1649 servers and routers.
1651 Added function silc_socket_set_heartbeat into the file
1652 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1653 If not set, the heartbeat is not performed. The actual
1654 heartbeat is implemented in the low level socket connection
1655 library. However, application is responsible of actually
1658 Added silc_server_send_heartbeat to send the actual heartbeat
1659 packet into silcd/packet_send.[ch]. Server now performs
1660 keepalive with all connections.
1662 * Added silc_task_get_first function into lib/silcutil/silctask.c
1663 to return the timeout task with shortest timeout. There was a bug
1664 in task unregistration that caused problems. TODO has been
1665 updated to include that task system must be rewritten.
1667 * The client library will now resolve the client information when
1668 receiving JOIN notify from server for client that we know but
1669 have incomplete information.
1671 * Rewrote parts of silc_server_remove_from_channels and
1672 silc_server_remove_from_one_channel as they did not remove the
1673 channel in some circumstances even though they should've.
1675 * Encryption problem encountered in server:
1677 The LEAVE command used to send the Channel Key packet to the
1678 router immediately after generating it. However, the code
1679 had earlier sent Remove Channel user packet but not immediately,
1680 ie. it was put to queue. The order of packets in the router
1681 was that Channel Key packet was first and Remove Channel User
1682 packet was second, even though they were encrypted in the
1683 reverse order. For this reason, MAC check failed. Now, this
1684 is fixed by not sending the Channel Key packet immediately but
1685 putting it to queue. However, this is more fundamental problem:
1686 packets that are in queue should actually not be encrypted
1687 because packets that are sent immediately gets encrypted
1688 actually with wrong IV (and thus MAC check fails). So, packets
1689 that are in queue should be encrypted when they are sent to
1690 the wire and not when they put to the queue.
1692 However, the problem is that the current system has not been
1693 designed to work that way. Instead, the packet is encrypted
1694 as soon as possible and left to the queue. The queue is then
1695 just purged into wire. There won't be any fixes for this
1696 any time soon. So, the current semantic for packet sending
1699 o If you send packet to remote host and do not force the send
1700 (the packet will be in queue) then all subsequent packets to the
1701 same remote host must also be put to the queue. Only after the
1702 queue has been purged is it safe again to force the packet
1705 o If you send all packets immediately then it safe to send
1706 any of subsequent packets through the queue, however, after
1707 the first packet is put to queue then any subsequent packets
1708 must also be put to the queue.
1710 Follow these rules and everything works fine.
1712 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Added new function silc_server_remove_clients_by_server to
1715 remove all client entries from ID list when the server connection
1716 is lost. In this case it is also important to invalidate all
1717 client entires as they hold the invalid server entry. This
1718 fixes fatal bug when server has lost connection and will reconnect
1721 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Made some sanity checks to silc_server_daemonise like to check
1724 whether the requested user and group actually exists.
1726 * Added sanity check to SKE's silc_ske_responder_finish to check
1727 that the public and private key actually is valid.
1729 * Invalidate the client's nickname when receiving Replace ID
1730 packet and the Client ID is being replaced. This means that the
1731 server will query the nickname if someone needs it (client)
1734 * Sort the ID Cache in client library when the ID Cache data
1735 has changed (needs sorting).
1737 * Do not allow for SILC client to create several connections to
1738 several servers. The client does not support windows right now
1739 and generating multiple connections causes weird behaviour.
1741 Irssi-silc client does support windows and can handle several
1742 connections without problems, see: www.irssi.org and SILC plugin.
1744 * Fixed some places where client was added to the IDList. The
1745 rule of thumb is following (in order to get everything right):
1746 If the client is directly connected local client then the
1747 `connection' argument must be set and `router' argument must be
1748 NULL to silc_idlist_add_client function. If the client is not
1749 directly connected client then the `router' argument must
1750 bet set and the `connection' argument must be NULL to the
1751 silc_idlist_add_client function.
1753 * The funtion silc_server_packet_send_local_channel actually did
1754 not check whether the client was locally connected or not. It
1755 does that now. Fixed a bug related to LEAVE command.
1757 * Fixed Remove Channel User payload parsing bug in server's
1758 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1760 * The server's silc_server_save_channel_key now checks also the
1761 global ID list for the channel as it might not be in the local
1762 list. Fixed a bug related to LEAVE command.
1764 * Is this the end of the [<unknown>] buglet that has been lurking
1765 around for a long time? A little for loop fix in server's
1766 silc_server_command_whois_parse that is used by both IDENTIFY
1767 and WHOIS command. At least, this was a clear bug and a cause
1768 of one type of [<unknown>] buglet.
1770 * WHOIS and IDENTIFY commands call the function
1771 silc_server_command_[whois/identify]_check function even if
1772 we are not router server.
1774 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Added --with-gmp configuration option. If set the GMP
1777 is always compiled in the SILC source tree. If not set then
1778 it is checked whether the system has the GMP3 installed. If
1779 it has then the GMP won't be compiled (the system's headers
1780 and library is used), if it doesn't have it then the GMP is
1781 compiled in the SILC source tree.
1783 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Changed RSA private exponent generation to what PKCS #1
1786 suggests. We try to find the smallest possible d by doing
1787 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1788 not security fix but optimization.
1790 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Added new config entry [Identity] to fork the server and run
1793 it as specific user and group. A patch from Bostik.
1795 * Imported Dotconf configuration library into lib/dotconf.
1796 This will be used to create the SILC configuration files later.
1797 It will appear in the distsribution after this commit.
1799 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * A big code auditing weekend happening. Auditing code for
1802 obvious mistakes, bugs and errors. Also, removing any code
1805 Removed files for being obsolete:
1807 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1808 inline in the file lib/silcutil/silcbuffer.h)
1810 o lib/silcutil/silcbufutil.c (the header has inline versions)
1812 Changed code to fix possible error conditions:
1814 o The buffer formatting routines now check that the destination
1815 buffer really has enough space to add the data. This applies for
1816 both buffer formatting and unformatting
1817 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1818 unformatting was changed to accomodate following rules:
1819 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1820 sent to the function while XXX_*STRING will not allocate or copy
1821 the data into the buffer. Instead it sets the pointer from the
1822 buffer into the pointer sent as argument (XXX_*STRING used to
1823 require that the pointer must be allocated already). This change
1824 makes this whole thing a bit more consistent and more optimized
1825 (note that the data returned in the unformatting with XXX_*STRING
1826 must not be freed now). The routines return now -1 on error.
1828 o Tried to find all code that use buffer_format and buffer_unformat
1829 and added return value checking to prevent formatting and
1830 especially unformatting errors and possible subsequent fatal
1833 o Changed ske->x and ske->KEY to mallocated pointers in
1834 lib/silcske/silcske.h. Fixed possible data and memory leak.
1836 o Added return value checking to all *_parse* functions. Fixed
1837 many memory leaks as well.
1839 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1840 so that buffer overflows would not happen. All code now also
1841 checks the return value as it can fail.
1843 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Added reconnection support to server if the normal server looses
1846 its connection to the router (for example if router is rebooted).
1847 The server performs normal reconnection strategy implemented
1848 to the server. Affected file silcd/server.c.
1850 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Added new packet type SILC_PACKET_SET_MODE that is used to
1853 distribute the information about changed modes (for clients,
1854 channels and clients channel modes) to all routers in the
1855 network. Updated the protocol specification accordingly.
1857 Added functions into silcd/packet_send.c and
1858 silcd/packet_receive.c: silc_server_send_set_mode,
1859 silc_server_set_mode.
1861 Added new files silcmode.[ch] into lib/silccore that implements
1862 the encoding and decoding of Set Mode Payload. Added new type
1863 SilcSetModePayload. Moved the definitions of different modes
1864 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1866 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1868 * Oops, a little mistake in server's connection authentication
1869 protocol. The protocol is not ended with FAILURE but with
1870 SUCCESS if the authentication is Ok. :) Affected file is
1873 * Implemented NICK_CHANGE notify handling in server in the file
1874 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1875 the local clients on the channel. After the changing nickname
1876 in router environment snhould work and the [<unknown>] nickname
1877 should appear no more.
1879 The silc_server_replace_id function that receives the Replace ID
1880 payload now sends the NICK_CHANGE notify type also in the file
1881 silcd/packet_receive.c
1883 * Changed WHOIS and IDENTIFY command to support the maximum amount
1884 of arguments defined in protocol specs (3328 arguments). This
1885 fixed a bug that caused problems when there were more than three
1888 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added extra parameter, command identifier, to the
1891 silc_client_send_command so that explicit command identifier
1894 Changed that ID list routines uses specific command identifier
1895 when sending WHOIS/IDENTIFY requests to the server so that they
1896 can be identified when the reply comes back.
1898 Affected files lib/silcclient/command.[ch],
1899 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1901 * Added `sender' argument to silc_server_packet_send_to_channel
1902 to indicaet the sender who originally sent the packet to us
1903 that we are now re-sending. Ignored if NULL. Affected file
1904 silcd/packet_send.[ch].
1906 * Added some server statistics support in silcd/server_internal.h
1907 SilcServerStatistics structure and around the server code. Also
1908 send some nice statistics information when client is connecting
1911 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Fixed channel ID decoding in server's JOIN command reply in
1914 silcd/command_reply.c
1916 * Fixed braodcasting of replace ID payload to not to send it if
1917 we are standalone server in silcd/packet_receive.c.
1919 * Fixed all channel message sending routines to not to send
1920 packets to clients that has router set, since they are routed
1921 separately in the same function earlier. Affects file
1922 silcd/packet_send.c and all channel packet sending functions.
1924 * In USERS reply, res_argv[i] are not allocated, the table
1925 is allocated. Thus changed that free the table, not its
1928 * In server's whois_check and identify_check if the client is
1929 locally connected do not send any WHOIS commands - they are not
1932 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Fixed some minor bugs in client when sending WHOIS command. The
1935 arguments was in wrong order.
1937 * Removed statis function add_to_channel from server in
1938 silcd/command.c that was previously used with the joining but
1941 * Tested USERS command in router environment successfully with two
1942 routers, two servers and two clients.
1944 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Reorganized the USERS command and command reply in client library
1947 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1948 When the command is given by user we register a pending command
1949 callback that will reprocess the command after the reply has been
1950 received from the server. When reprocessing the packet we then
1951 display the information. Thus, the USERS information is displayed
1952 now in the command callback instead of in the command reply
1953 callback. The processing of the command is same as previously
1954 when server has sent the command reply in the JOINing process.
1956 * Added to USERS command in silcd/command_reply.c to join the client,
1957 we didn't use to know about, to the channel after we've created
1958 a client entry for it. Also, for clienet we did know already still
1959 check whether it is on the channel or not and add it if not.
1961 * Removed silc_server_command_join_notify as the function and its
1964 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Changed the client's pending command handling to the same as the
1967 server's pending command handling. It is also now possible to
1968 execute command reply functions from other command reply
1969 function as the function callbacks for commands and command
1970 replies are one and same. The pending commands are not static
1971 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1972 in client connection context. Thus, pending commands are server
1973 connection specific as it is convenient.
1975 Changed the function silc_client_command_pending and
1976 silc_client_command_pending_del and added new function
1977 silc_client_command_pending_check. Removed the
1978 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1981 * Added cmd_ident, current command identifier, to the client
1982 connection context in lib/silcclient/client.h to keep track on
1983 command identifiers used in command sending. Client's command reply
1984 function handling now supports the mandatory command identifiers.
1986 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1987 funtions in client to fully support pending command callbacks.
1989 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1990 as one of the arguments to the application in the command reply
1993 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1994 before first releasing SILC but came back. Now it is removed again
1995 and should come back nomore. The FORWARDED flag was used only
1996 by the JOINing procedure by forwarding the command packet to router.
1997 Now, the JOINing procedure has been changed to more generic (due
1998 to various router environment issues) and FORWARDED is not needed
1999 anymore for anything. The protocol specification is yet to be
2002 Now, removed silc_server_packet_forward from server and the flag
2003 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2005 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Renamed NAMES command to USERS command. The NAMES was named that
2008 due to historical reasons. Now it is renamed. Also, rewrote
2009 parts of the USERS command. The nickname list is not sent anymore
2010 by the server. Only Client ID and mode lists are sent in the USERS
2011 command. Changed this also to the protocol specification.
2013 The client now resolves the names and stuff after it receives
2014 the USERS list from the server when joining to the channel.
2016 * WHOIS and IDENTIFY commands has been changed to support multiple
2017 Client ID's per command. One can now search for multiple users
2018 in the network by sending only one WHOIS or IDENTIFY command.
2019 Changed the code and the protocol specifications.
2021 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2022 uses silc_server_command_whois_parse to parse the request. */
2024 * If normal server, do not parse the WHOIS and IDENTIFY requests
2025 before sending it to the router. Saves some time.
2027 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Fixed JOIN command on client library. Wrong number of arguments
2030 used to crash the client.
2032 * Added silc_server_channel_has_global function to check whether
2033 channel has global users or not.
2035 * Added silc_server_channel_has_local function to check whether channel
2036 has locally connected clients on the channel.
2038 * The silc_server_remove_from_one_channel now checks whether the
2039 channel has global users or not after given client was removed from
2040 the channel. It also checks whether the channel has local clients
2041 on the channel anymore. If it does not have then the channel entry
2042 is removed as it is not needed anymore.
2044 * The silc_server_notify now checks on JOIN notify whether the joining
2045 client is one of locally connected or global. If it is global then
2046 the channel has now global users on the channel and that is marked
2047 to the channel entry. Also, it now saves the global client to
2048 global list who is joining and JOINs it to the channel. This is
2049 for normal server, that is.
2051 Changed silc_server_send_notify_on_channel,
2052 silc_server_packet_relay_to_channel and
2053 silc_server_packet_send_to_channel check if we are normal server
2054 and client has router set (ie. global client) do not send the
2055 message to that client, as it is already routed to our router.
2057 * Implemented LEAVE notify type handling in silc_server_notify
2060 * Tested LEAVE command in router environment successfully. Tested
2061 with two routers, two servers and two clients.
2065 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2067 * Implemented SIGNOFF notify type handling in silc_server_notify
2070 * silc_server_remove_id now removes the client entry from all channels
2071 it has joined and thusly sends SIGNOFF notify type.
2073 * Rewrote the NAMES list generation in server by removing two excess
2074 loops. The lists are created now inside one loop.
2076 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * silc_server_remove_channel_user checks now also global list
2079 for channel and client.
2081 * silc_server_new_channel_user checks now both local and global
2082 list for channel and client. Fixed a bug in client id decoding.
2083 Used to decode wrong buffer.
2085 * silc_server_channel_message checks now both local and global
2086 list for channel entry.
2088 * Tested channel joining (hence JOIN) in router environment
2089 successfully. Tested with two routers, two servers and two
2092 * Tested channel message sending in router environment successfully.
2094 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Added silc_server_save_channel_key into server.[ch] to save the
2097 received channel key in Channel Key payload processing. It is
2098 also used in JOIN command reply handling.
2100 Equivalent function silc_client_save_channel_key added into
2101 client.[ch] into client library.
2103 * Changed JOIN command reply to send information whether the channel
2104 was created or not (is existing already) and the channel key
2105 payload. Changed protocol specs accordingly.
2107 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2108 the request was sent by ID and not by nickname. Crashed on
2111 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2114 now correctly save the received data.
2116 * silc_server_free_sock_user_data now notifies routers in the
2117 network about entities leaving the network.
2119 At the same time implemented functions silc_server_remove_id
2120 and silc_server_send_remove_id to receive and send REMOVE_ID
2121 packets. The packet is used to notify routers in the network
2122 about leaving entities. The ID removed will become invalid in
2125 * Added function silc_idlist_del_server into server. Removes and
2126 free's server entry from ID list.
2128 * silc_server_private_message function now checks, if we are router,
2129 that the destination ID really is valid ID, naturally.
2131 * In router when NEW_ID packet is received (for new client) the
2132 hash of the Client ID is saved in the ID Cache but the
2133 client->nickname is set to NULL, instead of putting the hash
2136 IDENTIFY command now also checks that client->nickname must be
2137 valid. If it is not if will request the data from the server who
2138 owns the client. Added new function
2139 silc_server_command_identify_check.
2141 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2142 to set the command to already allocated Command Payload.
2144 * Tested private message sending in router environment with two
2145 routers, two servers and two clients. Fixed minor bugs and now
2148 * Fixed segfault from client's NAMES command. Used to crash if
2151 * Forwarded packets must not be routed even if it is not destined
2152 to the receiver. Changed server code comply with this.
2154 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Added `require_reverse_mapping' boolean value to ServerParams
2157 structure. If TRUE (not default) the server will require that
2158 the connecting host has fully qualified domain name.
2160 If the reverse mapping is not required and hostname could not be
2161 found the IP address is used as hostname.
2163 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Implemented version string checking to both client and server.
2166 The check is incomplete currently due to the abnormal version
2167 strings used in development version of SILC.
2169 * Changed all command functions in server to use the new
2172 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Changed char *data to unsigned char *data in ID Cache system to
2175 support binary data as ID Cache data. Changed code to support
2176 binary data in lib/silccore/idcache.c.
2178 * Renamed silc_server_packet_relay_command_reply to
2179 silc_server_command_reply as it is normal packet receiving
2180 function. Rewrote the function to accept command replys for
2181 servers and not only for clients.
2183 * Mark remote router always as registered server if we are connecting
2184 to it. Otherwise, commands sent by the router to us are ignored.
2186 * All ID List find routines now returns the ID Cache Entry pointer
2187 as well if requested.
2189 * WHOIS command works now in router environment, tested with two
2190 routers, two servers and two clients.
2192 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2193 in router environment (as it is almost equivalent to WHOIS) but
2194 hasn't been tested thoroughly. Added new functions:
2196 silc_server_command_identify_parse
2197 silc_server_command_identify_send_reply
2198 silc_server_command_identify_from_client
2199 silc_server_command_identify_from_server
2201 * Disabled route cache adding because adding two different ID's with
2202 same IP replaces the old cache entry thus giving wrong route.
2203 The entry->router->connection is always the fastest route anyway
2204 so route cache may not be needed. Of course, new routes maybe
2205 established after receiving the ID when the entry->router->connection
2206 might not be anymore the most optimal.
2208 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Add route cache for received ID for fast routing.
2212 * Added silc_server_packet_route to route received packet on router
2213 that is not destined to us.
2215 * Renamed silc_server_get_route to silc_server_route_get.
2217 * Added id_string and id_string_len fields into SilcServer to
2218 include encoded ServerID for fast comparing without excess
2219 encoding of the ID's.
2221 * Cleaned up WHOIS command on server side. Added following static
2224 silc_server_command_whois_parse
2225 silc_server_command_whois_check
2226 silc_server_command_whois_send_reply
2227 silc_server_command_whois_from_client
2228 silc_server_command_whois_from_server
2230 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2231 arguments in command replies. All command functions should be
2232 updated to use this macro.
2234 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Minor typo fixes on command reply handling on server.
2238 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added silc_server_command_add_to_channel internal routine to add
2241 the client to the channel after router has created the channel and
2242 sent command reply to the server.
2244 * Added generic silc_server_send_command to send any command from
2247 * Use static buffer with ID rendering instead of duplicating data.
2249 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Fixed a channel user mode bug when joining to a channel server gave
2252 everybody channel founder rights, oops.
2254 * We mark ourselves as the router of the incoming server connection
2255 if we are router ourselves. This way we can check in some packet
2256 sending functions whether it is locally connected server. For
2257 incoming router connections we put NULL.
2259 * For router sending packets locally means now always sending the
2260 packet cell wide; to local clients and local servers. For normal
2261 server sending packet locally means sending it to only local
2264 * Fixed the JOIN command to really work in router environment. If the
2265 channel is created it is always created by the router. Router is
2266 also responsible of making the initial joining to the channel,
2267 sending JOIN notify to the sending server and distributing
2268 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2269 does not exist server doesn't do anything else but forward the
2270 command to the router which performs everything.
2272 * Added silc_server_send_channel_key function to send the Channel Key
2275 * Added silc_server_create_channel_key to create new channel key. The
2276 channel key is now re-generated everytime someone joins or leaves
2277 a channel, as protocol dictates. Note: channel->key_len is the
2280 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2283 packet_receive.[ch] to separate packet sending and receiving
2284 routines. The server.[ch] now includes everything else including
2285 actual packet processing (writing and reading data) and other
2288 Renamed silc_server_private_message_send_internal to
2289 silc_server_send_private_message. The routine is still though
2290 used only to relay private messages as server does not send
2291 private messages itself.
2293 Renamed silc_server_new_channel to silc_server_create_new_channel
2294 and added new function sicl_server_new_channel that handles the
2295 incoming New Channel packet. Added also new sending function
2296 silc_server_send_new_channel to send New Channel Payload.
2298 * Added new function silc_server_notify to process incoming notify
2299 packet to the server/router. Server may then relay the notify
2300 to clients if needed.
2302 * Added new function silc_server_new_channel_user to process incoming
2303 New Channel User packet. Router will redistribute the packet and
2304 send JOIN notify to its local clients and locally connected servers
2305 if needed. Normal server will send JOIN notify to its local client
2306 on same channel when received this packet. Added also corresponding
2307 sending function silc_server_send_new_channel_user to sent the
2310 * Added boolean route argument to send_notif_to_channel and
2311 packet_send_to_channel functions to attempt to route the packet
2312 if it is TRUE and send only locally if it is FALSE.
2314 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * silc_server_replace_id now broadcasts the received replace ID
2317 packet if it is not broadcast packet already. The router must
2318 broadcast to inform other routers about changed ID.
2320 * Added backpointer to server's router into SilcServer context in
2321 silcd/server_internal.h.
2323 * Fixed silc_server_packet_broadcast to send correct broadcast
2326 * The channel key is now distributed to the local client as soon
2327 as it is received from the router (in router environment) so that
2328 no other packet may be sent for the channel until client has
2331 * silc_server_remove_channel_user now broadcasts the received
2332 Remove Channel User packet if it is not broadcast packet already.
2333 The router must broadcast to inform other routers about removed
2336 * Added users field into SilcPacketContext that is a reference count
2337 of the context. One can increase the reference count by calling
2338 silc_packet_context_dup which is now changed to just increase the
2339 reference count instead of duplicating the data. The reference
2340 count is decresed by calling silc_packet_context_free that will
2341 free the data after the reference count hits zero.
2343 For now on the packet context and everything allocated into it
2344 (including the raw packet from network) must be freed by calling
2345 the new silc_packet_context_free function. Added also new function
2346 silc_packet_context_alloc that must be used now to allocate the
2347 context. This also means that if a routine is asynchronous from
2348 silc_[client/server]_packet_parse_type the packet context must
2349 be duplicated by calling silc_packet_context_dup. Otherwise it
2350 gets free'd after silc_[client/server]_packet_parse_type returns.
2351 Also, one must remember that if packet is duplicated then its
2352 reference count must be decresed by calling the free function as
2353 many times as it was duplicated.
2355 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2356 from both client and server.
2358 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * Made joining to a channel working in router environment.
2362 * Cleaned up JOIN command on server side and create function
2363 silc_server_command_join_channel internal routine to make the
2366 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Changed silc_command_pending list to SilcDList. Also, added
2369 `ident' field to SilcServerCommandPending structure to identify
2370 the reply and to call correct callback.
2372 Added silc_server_command_pending_check function to replace the
2373 corresnponding macro. The silc_command_pending list is not
2376 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2377 to set identifier to previously allocated Command Payload. It
2378 is used to set identifier for command when resending Command
2381 * Added silc_command_payload_encode_payload to encode Command
2382 Payload buffer from SilcCommandPayload structure.
2384 * Added silc_argument_payload_encode_payload to encode Argument
2385 payload buffer from SilcArgumentPayload structure.
2387 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Changed WHOIS command to support router connection on server side.
2390 The whois request is always sent to router unless the server is
2391 standalone server. After server has received the reply from the
2392 router will it send the reply to the client.
2394 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2395 broadcast received broadcast packet. The function is used only
2396 by router. The broadcast packet is always sent to the router's
2399 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2400 render given ID to printable string, for log files for example.
2402 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Made basic router to router connections working. At least they
2405 can now connect to each other but nothing really works the way
2406 they are supposed - yet.
2408 * Added new initiator token to RouterConnection configuration
2409 file in silcd/serverconfig.[ch]. It is used to tell whether we
2410 are the initiator to the remote router or whether we'll expect
2411 the other end to connect.
2413 * Moved registering of listener task to silc_server_init, hence
2414 the server starts listenning as soon as it is run, even if it
2415 does not have connections to other routers. Let's see how well
2418 * Changed default connection retry timeouts for more suitable in
2421 * Removed cipher and such arguments from silc_idlist_add_client
2422 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2423 Added new function silc_idlist_add_data to add the keys and stuff
2426 * Added SilcIDListData structure and added it to SilcClientEntry
2427 and SilcServerEntry as their first field in the structure. This
2428 way we can explicitly cast the ID entries to the SilcIDListData
2429 structure and get common data for the entries. In past, we had
2430 to first check what type of connection it is and then cast it to
2431 correct ID entry type. Now, we can directly cast the opaque
2432 pointer to the SilcIDListData (no matter what ID entry it actually
2433 is) and get the data needed.
2435 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2438 in some circumstances even if threre were timeout tasks, though not
2439 IO tasks, but tasks anyway. Now fixed.
2441 * Defined SilcServerConnection structure to hold connection specific
2442 stuff about directly connected servers and routers. The definition
2443 is currently in silcd/server_internal.h. I thought about having
2444 a bit more important role fro this struct but for now it is used
2445 only when connecting to other server (or router actually).
2447 * Added connecting retry support in server when connecting to
2448 router(s). The retry feature implement exponential backoff
2449 algorithm. Also, added SilcServerParams structure to hold default
2450 parameters for server. For now, it include these retry settings
2451 and are hard coded. After server is moded to be as Silc Server
2452 Library this structure will be more important.
2454 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Changed client librarys channel->clients table to SilcList and
2457 changed code accordingly.
2459 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Changed client's channel table to SilcList and changed code
2462 accordingly. Also changed SilcChannelClientEntry to include back-
2463 pointer to the channel so that client entry can use that structure
2464 as list as well and we have fast cross-reference to the channel.
2465 This change dramatically decreased the complexity of channel
2466 handling with client entry and vice versa (removed one extra
2467 loop when searching for channel entry from many functions).
2469 * Changed server->sim from table to SilcDList and changed code
2472 * NAMES command can now be used from user interface. It will show
2473 the user list on the channel, neatly.
2475 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2476 Code now saves realname of the user if it becomes available.
2478 * Renamed configure.in to configure.in.pre and made ./prepare
2479 script to automatically add correct version string to
2480 configure.in which it creates from configure.in.pre.
2482 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * NAMES command reply now shows users mode with the nickname when
2487 * Moved silc_client_ch[u]mode[_char] functions from
2488 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2489 place sucks, they are utility functions and should be in some
2492 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2494 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2497 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added TRQ (efficient deque and list library) into lib/trq. This is
2502 a very good list library that is currently used in the SILC. Defined
2503 SilcList API over the library because I didn't like the API very
2504 much. See lib/trq/silclist.h for the API and examples of how to
2505 use the API. Fixed various places in the code to use the new
2506 SilcList API. The SilcList is meant for lists that has a structure
2507 already defined as a list. It is not suitable to add just some
2508 context to the list (in TRQ, the context is the list actually).
2510 So, I defined SilcDList that can be used for the purpose where
2511 predefined list structure does not exit. This can be used as
2512 such list. Now some context just can be added to the SilcDList.
2513 Currently this list is not used in the SILC just yet, though there
2514 are a lot places where this can replace dynamically allocated
2515 tables and I will fix these places, later, to use SilcDList.
2516 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2517 and use TRQ internally).
2519 Also fixed some annoying warning messages that the original TRQ
2520 code generated. Also minor changes to TRQ's Makefile.in.
2522 * Added support for querying by Client ID to both WHOIS and
2523 IDENTIFY commands into server, as required by the protocol.
2525 * Removed method function pointers from SilcBuffer structure. They
2526 weren't used to anything and just increased the context size for
2527 no good reason. This change also made silc_buffer_alloc and
2528 silc_buffer_free functions inline functions.
2530 * Disabled command flooding detection support until it's fixed so
2531 that it accepts commands in but does not execute them more than once
2534 * Added silc_net_localhost(), to return local hostname, into
2535 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2536 that must be initialized before calling silc_client_init.
2538 * Added new function: silc_server_send_notify_on_channels to send
2539 notify messages to all channels client has joined. It is assured
2540 that the message is sent only once per client.
2542 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2543 lib/silcutil/silcutil.[ch] as silc_format function. The new
2544 function is generic and is used by server as well, not only by
2545 the logging routines.
2547 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2548 the provided version string was not acceptable. Added new function:
2549 silc_ske_check_version into lib/silcske/silcske.h. The function
2550 must be implemented by the application (client or server) and it
2551 does not reside in the SKE library. The function checks the version
2552 string remote end sent.
2554 * Added back pointers (to opaque context and to SilcSocketConnection)
2555 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2557 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2558 duplicate packet context structure.
2560 * Changed `notify' client operation to send same arguments as client
2561 receives from server except for ID's. ID's are mapped to correct
2562 ID entry and that is returned. Also, if channel entry is not sent
2563 by server but the notify is for channel the channel entry is sent
2564 to application (otherwise application doesn't know that it is for
2565 channel (library gets it from packet's Destination ID)).
2567 * Added silc_client_remove_from_channels into client library to
2568 remove a client from all channels it has joined to. Used when
2569 received SIGNOFF notify from server. Added also new function
2570 silc_client_replace_from_channels to replace old ID entry with
2571 new ID entry on all channels. Used when received NICK_CHANGE
2574 * Fixed ID Cache list handling in silc_idlist_get_client in
2575 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2576 to get (or query) client by ID.
2578 * Updated TODO list.
2580 * Added connection authentication status message defined by the
2581 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2582 support for these into the code in client and server side.
2584 * Added generic function silc_client_send_command to send any command
2585 with variable argument list. Application should use this function
2586 to send commands if the command functions provided by the library
2587 does not suite for the application's user interface needs.
2589 * Added new `failure' client operation. Application is notified about
2590 received failure packet if client is executing a protocol. In this
2591 case the protocol's execution has failed.
2593 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2594 is required by the protocol.
2596 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2597 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2600 * Added status flag to SilcSKE object to indicate realtime status
2601 of the SKE protocol.
2603 * Application receives now exactly same command reply arguments as
2604 the library receives from server. However, if ID is received the
2605 corresponding ID entry is returned to the application (eg. Client
2606 ID is mapped to correct SilcClientEntry entry and that is returned).
2607 Changed command_reply client operation due to this change.
2609 * Changed all ID's in commands and in command replys as ID Payloads.
2610 Change affected both client and server side codes.
2612 All ID's sent in SILC network (with execption of ID's in SILC
2613 Packet header) are sent in ID Payload to support variable length
2616 * Server now notifies nick changes and notifies all clients on
2617 the channels about the new nickname (about the new Client ID,
2620 * Implemented CMODE command to change channel modes. Supports all
2621 channel modes defined by the protocol specs except ban and invite
2622 lists. (Also, private channel key mode is supported but support for
2623 setting private channel key in client is missing, thus, this mode
2624 has no effect on client side (except that server requires that the
2625 client uses private channel key and normal channel traffic does not
2628 Also, invite mode works per se, but INVITE command does not work
2629 yet correctly, so you can set channel as invite only channel but
2630 inviting clients to the channel does not work (it is yet to be
2631 thought what's the best way to do it).
2633 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2634 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2635 Implemented CUMODE command to change user's mode on the channel.
2636 Supports all modes defined by the protocol specs.
2638 * Added NAMES command reply to return users modes on the channel.
2640 * Removed unnecessary and slow ciphers from lib/silccrypt.
2642 * Set SO_KEEPALIVE option to connection sockets by default.
2644 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2646 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2647 redefined the Notify Payload into protocol specs.
2649 * Added silc_id_payload_parse_id to get ID directly from raw
2652 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2655 accept searching by Client ID as well.
2657 * Added support for LEAVE and SIGNOFF notify types in client library.
2659 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2660 to parse ID Payload from raw data.
2662 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Added flags parameter into silc_ske_assemble_security_properties
2665 function in lib/silcske/silcske.[ch].
2667 * Changed notify client operation to fit better for notify messages
2668 sent by server. The notify payload received from server is now
2669 passed to the application (after parsing it to SilcNotifyPayload).
2670 It is application's responsibility to retrieve the arguments
2671 from the payload and show the message the way it wants. The message
2672 sent by server is implementation specific.
2674 * Changed public keys to comply with the protocol specification.
2675 Old public keys are not supported anymore and are not compatible.
2677 * Removed nickname from Channel Payload as the latest draft removed
2678 it. The client must resolve the nickname from the NAMES command
2679 reply received when it joined the channel.
2681 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2683 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Fixed some errors in protocol specification drafts.
2687 * Created lib/silccore/silcnotify.c to implement Notify Payload
2688 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2689 generic payloads described by protocol specifications. The file
2690 includes implementations for ID Payload and Argument Payload.
2692 * Changed Command Payload implementation to use the new Argument
2693 Payload. Changed command_xxxx_payload to command_payload_xxxx
2694 to comply with SILC coding conventions.
2696 * Added suppport for Argument Payload handling in Notify Payload
2697 implementation as protocol requires it. Added the new support
2698 into server and client lib as well.
2700 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added support for multiple nicknames on same channel. [n] is
2703 added locally to the nickname if there are more than one same
2704 nicknames on the channel.
2706 * Server now sends all nicknames that matched WHOIS request.
2707 Client also shows the list received from server.
2709 * Added TOPIC command to client side. User can now set and show
2710 current topic on channel.
2712 * Added MOTD command to client and server. Also, server sends the
2713 motd when client connects to the server.
2715 * Changed version strings to comply ISO 8601.
2717 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Fixed protocol error handling in client library. It should now
2720 cope even if the SKE fails for some reason.
2722 * Made new protocol specification drafts for submitting to IETF.
2724 * Implemented TOPIC command to server in silcd/command.c.
2726 * Added two new notify types into lib/silccore/silcnotify.h:
2727 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2728 notify nickname change and topic setting/change on a channel.
2730 * API change of command_reply operation in client library. The
2731 application gets now the status type received from server as well.
2733 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2737 * Cras fixed and optimized the packet handling even further and
2738 it should work now. Minor change to the prototype of function
2739 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2741 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2743 * Added new function into lib/silcutil/silcschedule.[ch]:
2744 silc_schedule_with_fd to select() a specified fd. The function
2745 returns after timeout expires or data arrives or goes. The
2746 function is used by packet routines to wait that all data is
2747 received from network.
2749 * Fixed data reading from network in lib/silccore/silcpacket.c.
2750 The code now assures that all data is read from the fd and then
2751 continues packet processing. This was a bug fix since the code
2752 used to drop some data in some circumstances.
2754 * Added new function into lib/silcclient/client.[ch]:
2755 silc_client_start_key_exchange to start key exchange after
2756 connection has been established to server. The code internally
2757 now uses this funtion but its main purpose was to provide it
2758 for applications that perform their own connecting. After
2759 application has created a connection it merely calls this
2760 function to start the key exchange between client and server.
2761 The library takes care of everything else after that.
2763 Updated also lib/silcclient/README to explain the usage of
2766 * Do not send to application information that connection has
2767 been established. Application gets notified it by connect
2770 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Applied cras's patch to add silc_schedule_one function. The
2773 function runs scheduler once and returns.
2775 * Fixed the scheduler after cras messed it up. The timeout
2776 handling works now as it's supposed to work.
2778 * Added into lib/silccore/ silcnotify.h to include notify
2779 message types support. Changed silc_server_send_notify*
2780 functions, in server.[ch], to support those new notify types.
2781 Added the support for the notify types into client library,
2782 as well. Added new notify client operation into ops.h in
2785 * Changed silc_server_packet_send_to_channel to send normal
2786 packets instead of just channel message packets. The function
2787 is now used to send the notify packets to channels. It is not
2788 used to send channel message packets anymore, as server never
2791 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2792 va_arg()s as it seems to require it nowadays. I guess, if SILC
2793 is compiled with older va_arg() the new code should work anyway.
2795 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Splitted core library. Core library (lib/silccore) includes
2798 now only SILC protocol specific core (and common) components.
2799 Created new utility library (lib/silcutil) that includes more
2800 generic purpose stuff. The stuff for util library was taken
2801 from the old core library. This was minor and easy split.
2803 * Created SILC Client Library (lib/silcclient) that includes
2804 implementation of the SILC client without user interface. This
2805 was major move from silc/ directory. The code has been changed
2806 so that it is transparent towards the user interface. The
2807 silc/ directory includes now the same user interface as before
2808 and it uses the new client library. Read lib/silcclient/README.
2809 Basicly, the client library performs everything else related
2810 to SILC except user interface handling. Also, configuration
2811 files are considered to be part of user interface and library
2812 does not handle them.
2814 This change also changed a lot of structures, function naming etc.
2815 Most important change was that SilcClientWindow object was
2816 renamed to SilcClientConnection in the client library. Created
2817 also new file lib/silcclient/ops.h. Also added new files
2818 silc/local_command.[ch] and silc/client_ops.[ch].
2820 All these changes were made to make it easier for user interface
2821 designers to create what ever user interface for the SILC client
2824 It is also expected that the server will be moved to lib
2825 directory as well and SILC Server Library will be created;
2826 sometimes in the future.
2828 * Removed Local commands from lib/silccore/silccommand.h as
2829 they are application specific and new client library does not
2830 handle any of those anymore.
2832 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2833 old client implementation in silc/.
2835 * Added support for callback functions in SILC_LOG_* macros.
2836 Application can now set its own callbacks that will be called
2837 instead of using the default functions that will always print
2838 the debug messages to stderr (or stdout). Also, debugging can
2839 now be disabled by setting silc_debug to FALSE and re-enabled by
2840 setting it to TRUE. Note, that logging will still work even
2841 if debugging is disabled.
2843 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2844 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2845 silc_log_reset_debug_callbacks.
2847 * To enable debugging in silc client one must give now -d
2848 option on command line.
2850 * Changed silc_schedule_init to automatically allocate task queues
2851 if they are not allocated before calling it.
2853 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Added GMP 3.1 into math library.
2857 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2860 a channel in SILC network. The packet is used by servers and
2861 routers to notify other routers that user has left a channel.
2862 This little feature was missing until now. Added the feature
2863 to protocol specification as well.
2865 Added functions: silc_server_send_remove_channel_user and
2866 silc_server_remove_channel_user into server.[ch].
2868 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2869 lib/silccore/silcpacket.h. However, they are not implemented
2872 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Fixed joining to a channel and sending channel messages
2875 between server and router. The channel message sending should
2876 now work inside a cell.
2878 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Fixed the private message sending between server and router.
2881 The private message sending should now work inside a cell.
2883 * Added silc_server_replace_id into server.[ch] to replace
2884 existing ID in the SILC network.
2886 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2887 and silc_idlist_replace_server_id into idlist.[ch] in server.
2889 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Fixed the server to server connections. Server can again now
2892 connect to router. Router to router connections probably does
2895 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Added dynamic protocol registering support. Now protocols can
2898 registered and unregistered on the fly. Patch by cras.
2900 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Added lib/contrib directory to hold routines that some platforms
2903 don't have but are needed by SILC.
2905 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2906 into lin/contrib to provide getopt() and getopt_long() for
2907 those who don't have it.
2909 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Added AWAY command to client. When away message is set and
2912 client receives a private message packet the client automatically
2913 replies to the sender with the away message.
2915 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2916 bug seemed to be the cause of recent problems when compiling
2919 * Added version detection support to SKE protocol specification
2920 and added the new changes to the SKE implementation as well.
2921 There were other minor changes in the SKE protocol as well.
2923 Many changes in lib/silcske/silcske.[ch] and in
2924 lib/silcske/payload.[ch].
2926 * Added ^U functionality, clear input line. Patch from cras.
2928 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Mainly small bugfixes on core library. Fixed some debugging
2931 logging and buffer overflow in silclog.c.
2933 * Updated config.sub and config.guess on the distribution tree.
2935 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Added command lagging support in server. Client may execute
2938 commands now only once in two seconds.
2940 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Optimized packet reception. MAC computation and checking is now
2943 also more optimized. A lot previously duplicated code is now
2944 used as generic by both client and server.
2946 * Fixed key pair generation in clientutil.c
2948 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Added into lib/silccore/silcbufutil.[ch] new function;
2951 silc_buffer_realloc.
2953 * Moved generic packet sending/encryption functions to
2954 lib/silccore/silcpacket.[ch] from client and server. Some
2955 rewriting of the functions.
2957 * Moved all generic packet reception/decryption functions to
2958 lib/silccore/silcpacket.[ch] from client and server. The
2959 packet processing is now much cleaner in both client and server.
2960 These were major changes in both client and server.
2962 * Created many common functions in server to do packet sending.
2963 Previously code were duplicated a lot, this has been removed
2966 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Rewrote major parts of the ID cache system. Don't know
2969 whether it is better now or not but at least the API is more
2972 * Major rewrite on ID cache stuff on client because of the ID
2973 cache API changes. Added idlist.c to client.
2975 * Also major rewrite on ID cache stuff on server as well.
2976 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2977 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2978 in hand, instead they are all put into the ID cache system now.
2979 All server_idlist_* routines uses ID cache now instead of
2980 traversing its own lists (those lists does not exist anymore).
2981 SilcIDList though still exists. Also, SilcXXXEntry's are
2984 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Finally made the SKE implementation compliant to the protocol
2987 specification. All mp integers are now binary encoded as
2988 opposed being HEX encoded.
2990 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2993 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2994 functions: silc_[encode/decode]_pem. Also added function
2995 silc_encode_pem_file to PEM encode with newlines ('\n') for
2998 * SILC public keys are now encoded either PEM or binary. Same
2999 option is for private keys as well. By default private keys
3000 are binary encoded and public keys PEM encoded. Silly HEX
3001 encoding were removed.
3003 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3004 function to create fingerprints.
3006 * Fixed a bug in SHA1; does not change the original data anymore.
3008 * Partly implemented INFO command on client and server side.
3009 Fixed CLEAR command. Changes to SERVER command; show current
3010 server(s) when giving command without arguments. Added
3011 VERSION command to client.
3013 * Added check to server that unregistered connections cannot
3014 execute commands (unless it is specificly allowed).
3016 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed screen refresh.
3020 * Fixed channel joining bug from client. On some circumstances
3021 client tried to join to a channel it had already joined.
3023 * Added public key verification process into client's protocol.c.
3024 The client now verifies the public key from user and saves
3025 it into ~./silc/serverkeys/ directory.
3027 Added into: clientutil.[ch]: silc_client_verify_server_key.
3029 * Changed SKE protocol's silc_ske_initiator_finish function
3030 to accept callback function that verifies the received public
3031 key. Removed old silc_ske_verify_public_key function.
3033 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3036 silc_pkcs_private_key[_data]_set.
3038 * Made the password and public authentication more cleaner in
3039 server's protocol.c.
3041 * Removed historic and obsolete protocol `channel_auth' from
3042 both client and server.
3044 * Removed wrong way of sending command status messages from
3045 server to client in server's command.c. The old way violated
3046 protocol specification.
3048 Changes to silccore/silccommand.[ch]: removed
3049 silc_command_encode_status_payload -> not needed anymore,
3050 changed silc_command_encode_payload_va to accept extra
3051 argument on variable argument list. The argument type must
3052 now be provided to the function. Also, added new function:
3053 silc_command_encode_reply_payload_va which is same as
3054 normal command_encode_payload_va except command status type
3055 is provided as extra argument.
3057 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added ~./silc directory handling. The directory includes the
3060 public and private keys for the client.
3062 Added silc_client_check_silc_dir, silc_client_create_identifier
3063 and silc_client_load_keys.
3065 * Implemented SILC protocol compliant public key. Added public
3066 and private key saving to and loading from files.
3068 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3069 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3070 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3071 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3072 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3074 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3075 silc_pkcs_load_[public/private]_key.
3077 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Added silc_server_get_route (route.[ch]) to get connection
3080 data for the fastest route for given ID.
3082 * Implemented INVITE command on client and server. The command
3083 were re-defined in the SILC Protocol Specification and the
3084 implementation now complies with the specification.
3086 * Implemented PING command on client and server.
3088 * Implemented NAMES command on client and server. The server side
3089 supports currently only normal server not router server yet.
3090 Some changes to NAMES definition in SILC protocol specification.
3092 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Implemented LEAVE command on client and server.
3096 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3097 again. This change was made to the protocol as well. Server
3098 should not violate the protocol specification anymore.
3100 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3103 was tested. SOCKS4 was not but should work anyway.
