3 * Do not ask whether user wants to use the negotiated private key
4 for private messages, just use it. Affected file is
7 * Added `send_enc_key' and `enc_key_len' fields to the
8 SilcIDListData structure since they are needed in the re-key
9 phase. Affected file is silcd/idlist.[ch].
11 * Implemented the simple re-key protocol into the server.
12 Affected files silcd/server.c and silcd/protocol.[ch]. The
13 re-key will be performed once in an hour, by default.
15 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
16 Added silc_server_rekey, silc_server_rekey_callback and
17 silc_server_rekey_final.
19 * Removed Tunneled flag from the protocol. Updated the code
20 and the specifications.
22 * Adde `pfs' field to the SilcIDListData to indicate whether
23 the PFS is to be performed in the re-key. Affected file is
26 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
29 int64 of at least the xintXX size. If void * is less that 4
30 bytes uint32 * will be used. Defined bool as boolean.
32 * Changed _ALL_ unsigned long and unsigned int to uint32,
33 unsgined short to uint16 in the source tree.
35 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
36 not handle clients that has entry->data.registered == FALSE.
37 They are not in the network anymore. Affected file is
40 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Implemented the sending of the SERVER_SIGNOFF notify in the
43 server. Affected file is silcd/server.c.
45 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
46 Added also silc_notify_payload_encode_args into the
47 lib/silccore/silcnotify.[ch].
49 * Implemented ther SERVER_SIGNOFF notify handling in the server.
50 Affected file silcd/packet_receive.c.
52 * Implemented the SERVER_SIGNOFF notify handling in the client
53 library. Affected file lib/silcclient/client_notify.c. Also,
54 implemnted the printing of the SERVER_SIGNOFF info to the
55 application. Affected file silc/client_ops.c.
57 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
58 if the deleting was successful. Affected file silcd/idlist.[ch].
60 * Added support for public key authentication in the connection
61 authentication protocol in the client library. Affected file
62 lib/silcclient/protocol.c.
64 * Changed the server's silc_idlist_get_clients_by_* interface
65 to support already allocated array so that new entries may be
66 added to pre-allocated array. Affected file silcd/idlist.[ch].
67 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
70 * All command reply functions in the server now calls the
71 pending command callback even if error occured. This way the
72 error will be delivered to the client as well. Affected files
73 silcd/command.c and silcd/command_reply.c.
75 * Fixed INFO command to return local server's info if no server
76 was provided. Affected file lib/silcclient/command.c.
78 * Removed RESTART command for good. Updated the code and the
81 * Rewrote parts of the task system. It is a bit simpler now.
82 Removed unsued task priorities. The affected files are
83 lib/silcutil/silctask.[ch].
85 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Moved the USERS printing from the library to the application.
88 Affected files lib/silcclient/command.c and silc/client_ops.c.
90 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * Added channel key re-key support. The re-key is perfomed
95 only by the router and is done once in an hour. Added `rekey'
96 field to the SilcChannelEntry in the server. Affected files
97 silcd/server.c and silcd/idlist.h.
99 * Added silc_task_unregister_by_context into the file
100 lib/silcutil/silctask.[ch].
102 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
104 * Added SILC_UMODE_GONE mode to indicate when the client is not
105 present in the SILC network. Added also support to the local
106 command AWAY that will set this mode. Added support of showing
107 "xxx is gone" in WHOIS command. The USERS command shows the
110 * Fixed setting server and router operator privileges in the
111 server's UMODE command. Affected file silcd/command.c.
113 * Merged the SKE KE1 and KE2 payloads into one payload. The
114 new KE payload is equivalent to the old KE2 payload.
116 Cleaned up the SKE Start Payload parsing. It now uses the
117 simple buffer unformatting to do the parsing. A lot faster
120 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
121 to the SKE that is used to indicate whether both of the SKE
122 parties should perform authentication. By default only the
123 responder performs authentication. By setting this flag also
124 the initiator must do authentication. By default it is unset
125 since in normal SKE case, client to server connection, only
126 the responder should do authentication. When doing SKE between
127 two clients both should perform authentication. Updated the
128 code and the protocol specs.
130 * A little fix to IDENTIFY command in the server. Search the
131 client first by hash not nickname. Affected file is
134 * Fixed the silc_client_close_connection to support closing
135 the client to client connections wihtout deleting too much
136 data. Affected file lib/silcclient/client.c.
138 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
139 are received if protocol used to be active but is not anymore
140 the application would crash due to NULL pointer dereference.
141 Affected files silcd/server.c and lib/silcclient/client.c.
143 * Added `hash' field to the SilcClientConnection to include
144 the hash function negotiated in the SKE protocol.
146 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
147 to set the channel founder authentication data. A client can
148 claim the founder rights later by providing the authentication
149 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
150 This way the channel founder can regain the channel founder
151 privileges even it is left the channel. This works only on
152 local server and the client must be connected to the same
153 server to be able to regain the founder rights. Updated the
154 protocol specs accordingly.
156 Added support to the CMODE command in the client to set the
157 founder auth data. Read the README to see how to set it.
159 Added support to the CUMODE command to claim the founder
160 rights. Read the README to see how to do it.
162 Added support for the founder authentication to the Channel
163 Entry in the server. Affected file silcd/idlist.h.
165 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
166 server's CMODE command. Affected file silcd/command.c.
168 * Added the following new functions into lib/silccore/silcauth.[ch]:
169 silc_auth_get_method and silc_auth_get_data.
171 * The server now saves the remote hosts public key to the
172 SilcIDListData pointer. Affected file silcd/protocol.c.
174 * The normal server now does not remove the channel entry from
175 the cache if the founder authentication data is set. It used
176 to remove it if the founder was the last one on the channel on
177 the server and left the channel. The auth data is saved and
178 if the channel is re-joined later the old entry is used with
179 the old auth data. Affected files silcd/command_reply.c and
182 * Removed the `pkcs' field from the SilcIDListData structure
183 in the server; it is not used. Affected file silcd/idlist.h.
185 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed packet processing on slow links. Partial packets were
188 never re-processed because the incoming data buffer was cleared
189 by the application. Application must not directly clear the
190 sock->inbuf, the packet processing routines handle it. Fixed
191 this in client library and in server.
193 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Fixed the WHOIS and IDENTIFY send reply function to really
196 check whether to send list or just one entry. Affected file
199 * Cleaned up the LEAVE command's channel key distribution. The
200 affected file silcd/command.c.
202 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
203 can enforce the channel mode as well. In that case the ID
204 includes the ID of the server. The code now enforces the
205 mode change if the router have different mode than the server.
207 * The notify client operation with CMODE_CHANGE notify can now
208 return NULL client_entry pointer if the CMODE was not changed
209 by client. Application must check for this.
211 * Added <Server ID> argument to INFO command to support server
212 info fetching by Server ID.
214 * Added silc_server_announce_get_channel_users to get assembled
215 packets of channel users of the specified channel. Affected
216 file silcd/server.[ch].
218 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
219 was freed underneath the ID Cache.
221 * Re-announce clients when the server received CHANNEL_CHANGE
222 notify from the router. Affected file silcd/packet_send.c.
224 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
227 crashed since it did not handle the fact that there is no cipher
228 called "3" and didn't check the error condition. Now fixed.
230 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
231 flag. It can be used to send message requests.
233 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Implemented the RESTART command in the client.
237 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
238 notice type messages. Added notice printing to the user
241 * The channel keys are not re-generated if the channel's mode
242 is PRIVKEY, ie private key on the channel exists. Affected
243 files silcd/server.c and silcd/command.c.
245 * Fixed a little bug in channel message delivery when channel
246 private keys are set in the server. Affected file is
249 * Changed the setting on channel->on_channel = TRUE from the
250 silc_client_save_channel_key to the JOIN command reply. The
251 key payload is not received if the private channel key is set.
252 Affected file lib/silcclient/command_reply.c and the
253 lib/silcclient/client_channel.c.
255 * When the CMODE_CHANGE notify is sent and the channel private
256 key mode is removed the channel key must be re-generated in
257 other cells as well. Added this support for the router in the
258 silcd/packet_receive.c.
260 * Added new local command NOTICE to send notice message on
261 channel. Affected file silc/local_command.[ch].
263 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Added new local command ME to the client. It is used to send
266 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
267 some action. Affected file silc/local_command.[ch].
269 * Changed channel_message and private_message client operations
270 to deliver the message flags to the application. Added also
271 the `flags' arguments to the silc_client_send_channel_message
272 and silc_client_send_private_message functions. Affected file
275 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Redefined the Private Message Payload to support private message
278 keys and to support the new private message flags. Updated
279 the protocol specs. Flags makes it possible to have for example
282 * Added new type SilcPrivateMessagePayload and defined an API
283 for it in the lib/silcclient/silcprivate.[ch].
285 * Tested private message private keys successfully. Tested the
286 private message key set, unset and list commands with the new
289 * Redefined the Channel Message Payload to include the channel
290 message flags (equal with private message flags) to support
291 for example CTCP style messages.
293 * Defined some of the message (for channel and private message)
294 flags. Updated the protocol specs and added the flags to the
295 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
297 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * Added SilcKeyAgreementStatus type to the key agreement routines
300 to indicate the current status and error if one occured.
301 The status types are defined in the lib/silcclient/silcapi.h.
303 * Added new local command KEY that is used to set and unset private
304 keys for channels, set and unset private keys for private messages
305 with remote clients and to send key agreement requests and
306 negotiate the key agreement protocol with remote client. The
307 key agreement is supported only to negotiate private message keys,
308 it currently cannot be used to negotiate private keys for channels,
309 as it is not convenient for that purpose.
311 * Fixed a minor pending callback setting bug in the function
312 silc_client_get_client_by_id_resolve, now the function works.
313 Affected file lib/silcclient/idlist.c.
315 * Added function silc_net_get_local_port to get local bound
316 port by socket. Added to lib/silcutil/silcnet.[ch].
318 * Added `sockets' and `sockets_count' fields to the SilcClient
319 object. They hold the sockets of the listenning sockets in
320 the client. Listenning sockets may be for example the key
321 agreement server. Affected file lib/silcclient/client.[ch].
322 Added functions the silc_client_add_socket and the
323 silc_client_del_socket. They are exported to the application
326 * Added ~./silc/clientkeys to support other client's public keys.
328 * Renamed verify_server_key client operation to verify_public_key
329 and added one argument to indicate the type of the connection
330 (server, client etc.).
332 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Added silc_server_connection_auth_request to handle the
335 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
336 silcd/packet_receive.[ch].
338 * Added silc_server_send_connection_auth_request into the
339 silcd/packet_send.c to send the connection auth request packet.
341 * Cleaned up the silcd/protocol.c a bit and fixed some memory
344 * Fixed the public key authentication in responder side in the
345 server. The `auth_data' pointer includes the SilcPublicKey
346 not the path to the public key. Affected file silcd/protocol.c.
348 * Implemented the public key authentication in the initiator side
349 in the server. Affected file silcd/protocol.c.
351 * Removed the [RedirectClient] config section from the server
352 configuration. Is not needed and I don't want to implement it.
354 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Cleaned up the CMODE command in the server. It now works
357 correctly and supports all the modes defined in the protocol.
358 Affected file is silcd/command.c.
360 * Added `hmac_name' field to the SilcChannelEntry in the server
361 to hold the default HMAC of the channel. It can be set when
362 creating the channel (with JOIN command). Affected files
365 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
366 type to indicate the change of the current cipher and hmac
367 on the channel. Client can safely ignore the <cipher> argument
368 (if it chooses to do so) since the CHANNEL_KEY packet will
369 force the channel key change anyway. The <hmac> argument is
370 important since the client is responsible of setting the new
371 HMAC and the hmac key into use.
373 * Fixed the CMODE command in the client library as well.
375 * Tested CMODE command in router environment successfully.
377 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
379 * Show the version of the remote client (or server) when connecting
380 to the server. It is logged to the log file. Affected file
383 * Fixed the KILLED notify handling in the client library. The
384 client must be removed from all channels when receiving the
387 Also, do not remove the client entry when giving the KILL
388 command but when the KILLED notify is received.
390 * Removed silc_idlist_find_client_by_nickname from the server.
391 Not needed anymore. Affected files silcd/idlist.[ch].
393 * Implemented the CHANNEL_CHANGE notify type handling to the
394 server. Affected file silcd/server.c.
398 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Added silc_server_send_notify_invite to send the INVITE
401 notify between routers.
403 * Implemented the INVITE command correctly to the server.
405 * Implemented the INVITE notify type handling in the server.
407 * Implemented the INVITE command to the client library and on the
410 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Added function silc_server_get_client_resolve to find the
413 client entry by ID from all ID lists and then resolve it
414 (using WHOIS) if it cannot be found. Affected file is
417 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Implemented the BAN command to the client library.
421 * The JOIN command in the server now checks the invite list
424 * Changed the silc_command_reply_payload_encode_va and the
425 silc_command_payload_encode_va to support that if argument is
426 NULL it ignores and checks the next argument. Affected file
427 lib/silccore/silccommand.c.
429 * Added silc_server_send_notify_ban to send the BAN notify
430 type between routers.
432 * Chaned the silc_notify_payload_encode to support that if
433 argument is NULL it ignores and checks the next argument.
434 Affected file lib/silccore/silcnotify.c.
436 * Tested ban lists in router environment successfully.
438 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Implemented BAN command to the server, in silcd/command.[ch].
442 * Removed the BAN and INVITE_LIST modes from the CMODE command
445 * Added function silc_string_match to regex match two strings.
446 Affected files lib/silcutil/silcutil.[ch].
448 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Redefined parts of the SilcChannelEntry in the server to support
451 the new ban and invite lists.
453 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Redefined the INVITE command. The same command can be used to
456 invite individuals to the channel but also to manage the invite
457 list of the channel (to add to and remove from the invite list).
458 Updated the protocol specs.
460 * Added new command SILC_COMMAND_BAN that can be used to manage
461 the ban list of the channel. Updated the protocol specs.
463 * Removed the channel modes: the SILC_CMODE_BAN and the
464 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
465 in the CMODE command. The equivalent features are now available
466 using INVITE and BAN commands. Updated the protocol specs.
468 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
469 in the network about change in the current ban list. The notify
470 type is not used by the client.
472 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
473 support the invite lists.
475 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
477 * Added new function silc_string_regexify that converts string
478 including wildcard characters into regex string that can
479 be used by the GNU regex library. Added into the file
480 lib/silcutil/silcutil.[ch].
482 Added silc_string_regex_combine to combine to regex strings
483 into one so that they can be used as one regex string by
484 the GNU regex library. Added into the file
485 lib/silcutil/silcutil.[ch].
487 Added silc_string_regex_match to match two strings. It returns
488 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
490 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Imported GNU regex to the soruce tree into lib/contrib.
493 Fixed some compiler warning from the regex.c.
495 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Fixed MOTD command in the server to work in router environment.
499 * Fixed the MOTD command in the client library to support
500 the server argument in the command.
502 * Added `nickname_len' argument to the silc_idlist_add_client
503 in the server, as the `nickname' argument may be binary data
506 * Added silc_idlist_get_channels to return all channels from
509 * Implemented LIST command to the server. Affected file is
512 * Implemented the LIST command to the client library and on the
515 * Added [<user count>] argument to the LIST command reply.
516 With private channels the user count is not shown.
518 * Updated TODO and README.
520 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * The client entry's data.registered must be TRUE even with
523 global client entry on global client list. The data.registered
524 is used to check whether the client is anymore in the network,
525 for example with WHOWAS command so it must be valid.
527 * Fixed the WHOWAS command in the server. It now actually works
528 in router environment. Added function into silcd/command_reply.c
529 silc_server_command_reply_whowas_save.
531 * Added silc_idlist_purge function to the silcd/idlist.c
532 to periodically purge the ID Cache.
534 * Fixed INFO command in the server. It works now in router
535 environment. Added <server name> argument to the INFO command
536 reply. Updated the protocol specs.
538 * Fixed minor bug in silc_idcache_purge to not purge if the
539 expire value is zero.
541 * Fixed various bugs in WHOIS and IDENTIFY command handling as
542 they were buggy because of the WHOWAS information.
544 * Fixed local command MSG to handle the async resolving of
545 the remote client properly. It used to fail the first MSG.
546 Affected file silc/local_command.c.
548 * Added `data_len' field to SilcIDCache context.
550 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Update TODO. Todo in commands in the server.
554 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
557 used by routers as broadcast packet to inform other routers
558 about the changed user mode.
560 Implemented the notify handling in the server. Affected file is
561 silcd/packet_receive.c. Added the function
562 silc_server_send_notify_umode to the silcd/packet_send.[ch].
564 * Added new generic Channel Payload and deprecated the New Channel
565 Payload. The New Channel Payload is now the generic Channel
568 * Added new argument `mode' to the silc_server_send_new_channel
569 as it is required in the Channel Payload now.
571 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
572 and created a new and real SilChannelPayload to represent the
573 new generic Channel Payload. Implemented the encode/decode
574 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
576 * Added silc_server_get_client_channel_list to return the list
577 of channels the client has joined for WHOIS command reply.
578 Affected file silcd/server.[ch].
580 * Implemented the channel list sending in the WHOIS command reply
581 in server and in the client.
583 Implemented the channel list displaying on the user interface
584 as well. Affected file silc/client_ops.c.
586 * Added silc_channel_payload_parse_list to parse list of Channel
587 Payloads. It returns SilcDList list of SilcChannelPayloads.
588 Client for example can use this function to parse the list of
589 channels it receives in the WHOIS command reply. The caller
590 must free the list by calling silc_channel_payload_list_free.
591 Affected files lib/silccore/silcchannel.[ch].
593 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Added one new argument <user mode> to the WHOIS command reply
596 to return the mode of the user in SILC. Updated the protocol
599 Implemented it to the server and client.
601 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Fixed the mode printing on the user interface on joining.
604 Affected file silc/client_ops.c.
606 * Implemented the UMODE command and user modes in general to the
607 client library and to the user interface.
609 * Implemented the UMODE command to the server.
611 * The server now sends UNKNOWN_COMMAND error status if client sends
612 unknown command. Affected file silcd/command.c.
614 * All server commands now handle the command identifier the right
615 way when sending the command reply to the client. The client can
616 use to identify the command replies with the identifier.
618 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Added silc_server_get_client_route to resolve the route to
621 the client indicated by the client ID. Affected file is
624 * Added silc_server_relay_packet as general function to relay
625 packet to arbitrary destination. This deprecates functions
626 like _send_private_message_key, _relay_notify etc. Affected
627 file is silcd/packet_send.[ch].
629 Removed silc_server_send_key_agreement,
630 silc_server_send_private_message_key and
631 silc_server_packet_relay_notify functions from the file
632 silcd/packet_send.[ch].
636 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
637 server. Affected file silcd/packet_receive.[ch].
639 * Implemented the KILL command to the client. Implemented the
640 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
641 Affected files lib/silcclient/command[_reply].c and
642 lib/silcclient/client_notify.c. Implemented the KILL notify
643 printing in the user inteface.
645 * Fixed a lot silc_parse_nick memory leaks from the client
646 library in the file lib/silcclient/command.c.
648 * Changed the silc_server_send_notify_on_channels's `sender'
649 argument from SilcSocketConnection to SilcClientEntry to
650 check the sender as entry and not as connection object and not
651 to send to the client provided as argument. The affected file
652 is silcd/packet_send.[ch].
654 * The notify packets that are destined directly to the client used
655 to not to be processed by the server. Now changed that and the
656 server processes all notify packets. After relaying the packet
657 to the client the notify packet is processed in the server.
659 * The silc_server_free_client_data now checks whether there is
660 pending outgoing traffic for the client and purges the data to
661 the network before removing the client entry.
663 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
666 an client is killed from the SILC Network. Updated the protocol
669 Added new function silc_server_send_notify_killed to the
670 silcd/packet_send.[ch].
672 * Added function silc_server_packet_relay_notify to relay notify
673 packets that are destined directly to a client. In this case
674 the server does not process the notify packets but merely relays
675 it to the client. Affected file silcd/packet_send.[ch].
677 Added also silc_server_packet_process_relay_notify to check
678 whereto relay the notify. Affected file is
679 silcd/packet_receive.[ch].
681 * Implemented the KILL command to the server.
685 * Added the backup schema desgined last fall to the protocol
686 specs for everyone to see. The specification is in the
687 *-spec-xx.txt draft and the packet type definitions for the
688 backup routers is in *-pp-xx.txt draft. Thusly, added also
689 new packet type SILC_PACKET_CELL_ROUTERS.
691 * A big security problem in the implementation discovered. The
692 signoff of an client did not cause new channel key generation
693 which it of course should've done. The channel keys must be
694 always re-generated when client leaves (or signoffs) the channel.
695 The silc_server_remove_from_channels funtion now handles
696 the channel key re-generation.
698 * Added `sender' argument to the silc_server_send_notify_on_channels
699 to not to send the client provided as argument. Affected file
700 silcd/packet_send.[ch].
702 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Implemented OPER and SILCOPER commands into the server and
707 * Added silc_auth_verify and silc_auth_verify_data to verify
708 the authentication directly from the authentication payload.
709 It supports verifying both passphrase and public key based
710 authentication. Affected file lib/silccore/silcauth.[ch].
712 * Added `hash' field to the SilcIDListData structure. It is the
713 hash negotiated in the SKE protocol. Affected file is
716 * Slight redesigning of the SilcAuthPayload handling routines.
717 Do not send SilcPKCS but SilcPublicKey as argument.
719 * Implemented the public key authentication support to the
720 serverconfig. The public key is loaded from the provided path
721 and saved as authentication data to void * pointer. Thus,
722 changed the unsigned char *auth_data to void *auth_data;
724 * Fixed SHUTDOWN command to send the reply before the server
725 is shutdown. :) Affected file silcd/command.c.
727 * Fixed fatal bug in CONNECT command. The hostname was invalid
728 memory and server crashed. Affected file silcd/command.c.
730 * Fixed fatal bug in CLOSE command. The server_entry became
731 invalid but was referenced later in the command. Affected file
734 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Fixed fatal bug in failure packet handling. Server ignored
737 the failure and thus crashed when it came.
741 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
744 that the command may be executed only once in (about) 2 seconds.
745 The old SILC_CF_LAG flag is same but allows command bursts up
746 to five before limiting.
748 Added the support for CF_LAG and CF_LAG_STRICT flags to the
749 server code. Various commands now includes the CF_LAG_STRICT
750 flag to disallow any kind of miss-use of the command.
752 * Fixed the silc_buffer_unformat to not to allocate any data
753 if the length of the data is zero. It used to allocate the
754 length + 1. Affected file lib/silcutil/silcbuffmt.c.
756 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Changed the format of AdminConnection configuration section
759 in the server. Added username of the admin to the format.
760 Affected files silcd/serverconfig.[ch].
762 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
763 to return admin configuration data by host, username and/or
766 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
768 * Implemented WHOWAS command to the server. Added the functions:
770 silc_server_command_whowas_parse,
771 silc_server_command_whowas_send_reply,
772 silc_server_command_whowas_from_client and
773 silc_server_command_whowas_from_server
775 * Added <Client ID> argument to the WHOWAS command reply. Updated
776 the protocol specs accordingly.
778 * Implemented WHOWAS command and command_reply to the client
781 Implemented the WHOWAS printing on the user interface.
783 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Added new argument to the WHOWAS command reply, the real name.
786 It is an optional argument. Updated the protocol specs.
788 * Added SilcIDCacheDestructor callback that is registered when
789 the SilcIDCache is allocated. The callback is called when
790 an cache entry in the ID Cache expires, or is purged from the
791 cache. Added into lib/silccore/idcache.[ch].
793 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
794 to destruct the client entries when the cache entry expires.
795 Other ID Cache's in server and in the client library ignores
798 * If the ID Cache entry's `expire' field is zero then the entry
799 never expires. Added boolean `expire' argument to the
800 silc_idcache_add function in the lib/silccore/idcache.[ch].
801 If it is TRUE the default expiry value is used.
803 * Added silc_server_free_client_data_timeout that is registered
804 when client disconnects. By default for 5 minutes we preserve
805 the client entry for history - for WHOWAS command.
807 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Added support to the server to enforce that commands are not
810 executed more than once in 2 seconds. If server receives
811 commands from client more frequently, timeout is registered
812 to process the commands. Affected file silcd/command.c.
813 Added new function silc_server_command_process_timeout.
815 * Changed NICK_NOTIFY handling in client library to check that
816 if the client's nickname was changed, so there is no need to
817 resolve anything from the server.
819 * Removed error printing from the WHOIS and IDENTIFY commands.
820 If error occurs then it is ignored silently in the client library.
821 The application, however, may map the received error to
822 human readable error string. The application currently maps
823 the NO_SUCH_NICKNAME error to string.
825 * Made the command status message public to the application. Moved
826 them from lib/silcclient/command_reply.c to
827 lib/silcclient/command_reply.h. The application can map the
828 received command status to the string with the
829 silc_client_command_status_message function.
831 * Added check to the server to check that client's ID is same
832 as the Source ID in the packet the client sent. They must
835 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Added dist-bzip hook to the Makefile.am to make bzip2
838 compressed distributions.
840 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * Server now enforces the maximum length for the nickname and
843 the channel as protocol specification dictates. 128 bytes for
844 nickname and 256 bytes for channel name.
846 * Moved the WHOIS printing to the application. The client libary
847 does not print out the WHOIS information anymore, the application
848 must do it. Renamed silc_client_command_reply_whois_print to
849 the silc_client_command_reply_whois_save.
851 The client's idle time is also sent to the application now, and
852 the idle is shown on screen.
854 * Added silc_client_command_reply_identify_save to save the
855 received IDENTIFY entries.
857 * Do not check for channel private keys in message sending and
858 reception if the channel does not have the PRIVKEY mode set.
859 Affected file lib/silclient/client_channel.c.
861 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
863 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
864 just surfaced after chaning the JOIN procedure.
866 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Added silc_client_get_clients_by_list to get client entries
869 from Client ID list, that is returned for example by JOIN
870 and USERS command replies. The application should use this
871 function for example when JOIN command reply is received to
872 resolve the clients already on the channel (library does not
873 do that anymore as USERS command reply is not used in the JOIN
874 procedure anymore). Affected files lib/silcclient/silcapi.h and
875 lib/silcclient/idlist.c.
877 * JOIN command reply and USERS command reply returns now SilcBuffer
878 pointers instead of unsigned char pointers when returning
879 the client list and mode list.
881 * Added <Client ID> argument to the JOIN command reply, mainly
882 for the server to identify for which client the command was
883 originally sent. Updated protocol specs accordingly.
885 * Added SilcDlist private_key pointer to the SilcChannelEntry
886 in the client to support the channel private keys. Affected
887 file is lib/silcclient/idlist.h.
889 * Added SilcChannelPrivateKey argument to the function
890 silc_client_send_channel_message so that application can choose
891 to use specific private ke if it wants to. If it is not provided,
892 the normal channel key is used, unless private keys are set.
893 In this case the first (key that was added first) is used
894 as the encryption key.
896 * Implemented the support for channel private key handling.
897 Implemented the following functions:
899 silc_client_add_channel_private_key,
900 silc_client_del_channel_private_keys,
901 silc_client_del_channel_private_key,
902 silc_client_list_channel_private_keys and
903 silc_client_free_channel_private_keys
905 Affected file lib/silcclient/client_channel.c.
907 * Added the support for the private keys in the channel message
908 sending and encryption and in the message reception and
909 decryption. Affected funtions are
910 silc_client_send_channel_message and silc_client_channel_message.
912 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added SKE's key verify callback to the client library's
915 KE protocol context. Affected files lib/silcclient/protocol.[ch].
917 * Removed the statement that server (or router) must send USERS
918 command reply when joining to the channel so that the client
919 knows who are on the channel. Instead, the client list and
920 client's mode list is now sent in the JOIN command reply to the
921 client who joined channel. This is better solution.
923 * Added function silc_server_get_users_on_channel and function
924 silc_server_save_users_on_channel to the silcd/server.[ch].
926 * Removed function silc_server_command_send_users from the
929 * Do not show topic on the client library anymore. The topic is
930 sent in the command reply notify to the application and the
931 application must show the topic now.
933 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Added client searching by nickname hash into the IDENTIFY and
936 WHOIS commands in the server as they were clearly missing from
937 them. Affected file is silcd/command.c.
939 * Fixed a bug in private message receiving in the client library.
940 The remote ID was freed and it wasn't supposed, now it is
943 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Minor fix to the channel payload; allocate the data area, as it
946 needs to be of specific length.
948 * If the key agreement port is zero then the operating
949 system will define the bound port. Affected files are
950 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
952 * Added new function silc_channel_payload_decrypt into the file
953 lib/silccore/silcchannel.[ch].
955 * Moved the channel message etc, check from silc_packet_decrypt
956 to applications. The library calls now a generic
957 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
958 when the packet is either normal or special. This was done to
959 allow more wide range of checking that was not allowed when
960 the code was in library. Now applications can do virtually any
961 checks to the packet and return to the library the decision how
962 the packet should be processed. Affected files are
963 lib/silccore/silcpacket.[ch].
965 Added silc_server_packet_decrypt_check to the server and
966 silc_client_packet_decrypt_check to the client library.
968 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
969 to send with specified source and destination information.
971 * Channel message delivery between routers was broken after the
972 channel key distribution was fixed earlier. The channel key
973 was used be to distributed to other routers as well which is not
974 allowed by the protocol. Now this is fixed and channel keys
975 really are cell specific and the channel message delivery between
976 routers comply with the protocol specification.
978 * Fixed various commands in server to check also the global list
979 for the channel entry and not just the local list. The affected
980 file silcd/command.c.
982 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added assert()s to buffer formatting and unformatting routines
985 to assert (if --enable-debug) when error occurs. Affected
986 file: lib/silcutil/silcbuffmt.c.
988 * Changed to auto-reconnect to check whether the remote host is
989 router and register the re-connect timeout if it is. It used
990 to check that whether we are normal server, but router must do
991 auto-reconnect with another router as well. Affected file
994 * Removed the [<key len>] option from CMODE command as the cipher
995 name decides the key length, nowadays. See the defined ciphers
996 from the protocol specification.
998 * Added [<hmac>] option to the CMODE command to define the HMAC
999 for the channel. Added SILC_CMODE_HMAC channel mode.
1001 * Added [<hmac>] option for the JOIN command so that user can
1002 select which HMAC is used to compute the MACs of the channel
1005 * Added Hmac field to the Channel Message Payload. The integrity
1006 of plaintext channel messages are now protected by computing
1007 MAC of the message and attaching the MAC to the payload. The
1008 MAC is encrypted. Now, it is clear that this causes some
1009 overhead to the size of the packet but rationale for this is that
1010 now the receiver can verify whether the channel message decrypted
1011 correctly and also when private keys are set for the channel the
1012 receiver can decrypt the packet with several keys and check from
1013 the MAC which key decrypted the message correctly.
1015 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1016 lib/silccrypt/silccipher.[ch].
1018 * Added silc_hash_len to return the digest length into the
1019 lib/silcrypt/silchash.[ch].
1021 * Rewrote parts of Silc Channel Payload interface in the
1022 lib/silccore/silcchannel.[ch]. The encode function now also
1023 encrypts the packet and parse function decrypts it.
1025 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Fixed a minor formatting bug in the SKE's key material processing.
1028 It actually might have processed the keys wrong way resulting
1031 * Redefined the mandatory HMAC algorithms and added new algorithms.
1032 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1033 and hmac-md5 truncated to 96 bits. The mandatory is now
1034 hmac-sha1-96. Rest are optional (including the one that used
1035 to be mandatory). Rationale for this is that the truncated HMAC
1036 length is sufficient from security point of view and can actually
1037 make the attack against the HMAC harder. Also, the truncated
1038 HMAC causes less overhead to the packets. See the RFC2104 for
1041 * Added new [hmac] configuration section. The SKE used to use
1042 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1043 is of course wrong. The official names that must be proposed in
1044 the SKE are the ones defined in the protocol specification
1045 (hmac-sha1-96 for example). The user can configure any hmac
1046 using any hash function configured in the [hash] section. At
1047 least, the mandatory must be configured.
1049 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1051 * Added HMAC list to the SKE proposal list. It has now both
1052 hash algorithm list and HMAC list. This makes the protocol
1053 incompatible with previous versions. The SKE now seems to work
1054 the way it is supposed to work, for the first time actually.
1056 * Defined plain Hash algorithms to the protocol specification.
1059 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Implemented support for key agreement packets into the server.
1062 Added functions silc_server_key_agreement and
1063 silc_server_send_key_agreement. Other than these functions,
1064 server has nothing to do with this packet.
1066 * Added support for private message key packets into the server.
1067 Added functions silc_server_private_message_key and
1068 silc_server_send_private_message_key.
1072 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1073 called in the protocol's final callback instead in the END
1074 protocol state. This makes a little more sense and in the same
1075 time in client we can use the same protocol routines for normal
1076 key exchange and to key agreement packet handling as well.
1078 * Added to both client's and server's KE protocol context the
1079 SilcSKEKeyMaterial pointer to save the key material. We will
1080 bring the key material to the protocol's final callback by doing
1081 this. The final callback must free the key material.
1083 * Added SKE's packet_send callback into client's KE protocol
1084 context so that the caller can choose what packet sending function
1085 is used. This way we can use different packet sending when
1086 doing normal SKE when doing key agreement packet handling (in
1087 the key agreement packet handling we do not want to encrypt
1090 * Implemented the responder side of the key agreement routines
1091 in the client. The client can now bind to specified port and
1092 accept incoming key negotiation. The key material is passed
1093 to the application after the protocol is over.
1095 * Implemented the processing of incoming Key Agreement packet
1096 in the client. Added function silc_client_key_agreement to
1099 * Implemented the intiator side of the key agreement routines
1100 in the client. The client can now initiate key agreement with
1101 another remote client. The key material is passed to the
1102 application after the protocol is over.
1104 * Created client_keyagr.c to include all the key agreement
1107 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1108 SILC_TASK_CALLBACK except that it is not static.
1110 * Created client_notify.c and moved the Notify packet handling
1111 from the client.[ch] into that file.
1113 * Created client_prvmsg.c and moved all private message and
1114 private message key routines from the client.[ch] into that file.
1116 * Create client_channel.c and moved all channel message and
1117 channel private key routines from the client.[ch] into that file.
1119 * Changed silc_client_get_client_by_id_resolve to resolve with
1120 WHOIS command instead of IDENTIFY command, in the file
1121 lib/silclient/idlist.c.
1123 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Implemented the SKE's responder side to the Client library.
1127 * When FAILURE is received to the protocol do not trust it
1128 blindly. Register a timeout to wait whether the remote closes
1129 the connection as it should do it, only after that process the
1130 actual failure. This was changed to both client and server.
1132 * Added client_internal.h to include some of the structures
1133 there instead of client.h in lib/silcclient/.
1135 * Added function silc_task_unregister_by_callback to unregister
1136 timeouts by the callback function.
1138 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Some "Incomplete WHOIS info" errors has been appearing on the
1141 log files. Took away the entry->userinfo check from WHOIS
1142 reply sending. The entry->userinfo is now " " if client did not
1143 provide one. I thought this was fixed earlier but something
1144 is wrong still. Let's see if the error still appears.
1146 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Fixed a minor bug in the login when the channel key is
1149 re-generated in the server. It used to generate the key in
1150 wrong order and thus caused problems in the channel traffic.
1152 * Fixed a minor bug in channel key distsribution after
1153 KICK command. The key was not sent to the router even though
1156 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Added silc_ske_process_key_material_data as generic routine
1159 to process any key material as the SILC protocol dictates. The
1160 function is used by the actual SKE library but can be used by
1161 applications as well. This relates to the private message keys
1162 and the channel private keys since they must be processed the
1163 same way the normal SILC session keys. The protocol dictates
1164 this. Affected files: lib/silcske/silcske.[ch].
1166 Added also silc_ske_free_key_material to free the
1167 SilcSKEKeyMaterial structure.
1169 * Defined silc_cipher_set_key function to set the key for
1170 cipher without using the object's method function. The affected
1171 files: lib/silccrypt/silccipher.[ch].
1173 * Implemented silc silc_client_add_private_message_key,
1174 silc_client_add_private_message_key_ske,
1175 silc_client_del_private_message_key,
1176 silc_client_list_private_message_keys and
1177 silc_client_free_private_message_keys functions in the
1180 Added functions silc_client_send_private_message_key to send
1181 the Private Message Key payload and silc_client_private_message_key
1182 to handle incoming Private Message Key payload.
1184 * Added Cipher field to the Private Message Key payload to set
1185 the cipher to be used. If ignored, the default cipher defined
1186 in the SILC protocol (aes-256-cbc) is used.
1188 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Removed lib/silcclient/ops.h file.
1192 Redefined parts of the SILC Client Library API. Created new
1193 file silcapi.h that deprecates the ops.h file and defines the
1194 published Client Library API. Defined also private message key
1195 API and channel private key API into the file.
1197 This is the file that the application must include from the
1198 SILC Client Library. Other files need not be included by
1199 the application anymore.
1201 * Added new key_agreement client operation callback and also
1202 defined the Key Agreement library API for the application.
1204 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1207 is used by clients to request key negotiation between another
1208 client in the SILC network. If the negotiation is started it
1209 is performed using the SKE protocol. The result of the
1210 negotiation, the secret key material, can be used for example
1211 as private message key.
1213 Implemented the Key Agreement payload into the files
1214 lib/silccore/silauth.[ch].
1216 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Redefined ciphers for the SILC protocol. Added some new ciphers
1219 and defined the key lengths for the algorithms. Changed the
1220 code accordingly. The default key length is now 256 bits.
1222 * Fixed SKE key distribution function silc_ske_process_key_material
1223 when the key length is more than 128 bits. The default key
1224 length in SILC is now 256 bits.
1226 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1227 to indicate unsupported algorithm.
1229 * Renamed rijndael.c to aes.c and all functions as well.
1231 * Fixed a long standing channel key setting bug in client library.
1232 Weird that it has never surfaced before.
1234 * Fixed bug in channel deletion. If the entire channel is removed
1235 then it must also delete the references of the channel entry
1236 from the client's channel list as the client's channel entry and
1237 the channel's client entry share same memory.
1239 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Implemented CONNECT and SHUTDOWN commands in the client.
1243 * Implemented CLOSE command to the client.
1245 * Added the function silc_idlist_find_server_by_name into the
1246 files silcd/idlist.[ch].
1248 Added the function silc_idlist_find_server_by_conn into the
1249 files silcd/idlist.[ch].
1251 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * DIE command was renamed to SHUTDOWN. Updated the both code
1256 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1257 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1259 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1262 * Added function silc_server_create_connection function to create
1263 connection to remote router. My server implementation actually
1264 does not allow router to connect to normal server (it expects
1265 that normal server always initiates the connection to the router)
1266 so the CONNECT command is only good for connecting to another
1269 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1272 or some other client was kicked from the channel.
1274 Implemented the handling of the notify type to both client
1277 Implemented silc_server_send_notify_kicked to send the KICKED
1278 notify. It is used to send it to the server's primary router.
1280 * Implemented the KICK command into server and client.
1282 * Added `query' argument to the silc_idlist_get_client function
1283 to indicate whether to query the client from server or not if
1286 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1287 to indicate that the client is not channel founder.
1291 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1293 * Removed the rng context from SilcPacketContext structure and
1294 changed that the packet routine uses the Global RNG API.
1296 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added support for quit message that client can "leave" on the
1299 channel when it quits the SILC. It is ditributed inside the
1300 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1302 Added silc_server_free_client_data that will take the
1303 signoff message as argument.
1305 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1307 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Updated parts of the protocol specification to keep it up
1312 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1315 payloads in one packet.
1317 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1318 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1319 use now the new List flag.
1321 * Also deprecated the following packet types: REPLACE_ID,
1322 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1324 * Added list support for Notify packet in server.
1326 * Added silc_server_send_notify_channel_change to send the
1327 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1328 the silc_server_send_replace_id.
1330 * Added silc_server_send_notify_nick_change to send the
1331 NICK_CHANGE notify type. Deprecates the function
1332 silc_server_send_replace_id.
1334 * Added silc_server_send_notify_join to send the JOIN notify type.
1335 Deprecates the function silc_server_send_new_channel_user.
1337 * Added silc_server_send_notify_leave to send LEAVE notify type.
1338 Deprecates the function silc_server_send_remove_channel_user.
1340 * Added silc_server_send_notify_cmode and
1341 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1342 types. Deprecates the silc_server_send_set_mode function.
1344 * Added SERVER_SIGNOFF notify type to indicate that server has
1345 quit. This means that all clients on the channel from that
1346 server will drop. This can be also used when netsplit happens.
1348 Deprecated REMOVE_ID packet type since it is not needed anymore
1351 Added silc_server_send_notify_server_signoff to send the
1352 SERVER_SIGNOFF notify type. Deprecates the function
1353 silc_server_send_remove_id.
1355 Added also silc_server_send_notify_signoff to send the
1356 SIGNOFF notify type.
1358 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1359 SILC protocol from this day on. Changed the protocol
1360 specification as well.
1362 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1363 notify type. It is used between routers to notify about
1364 topic changes on a channel.
1366 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1369 * Partly updated the protocol specification to comply with the
1370 changes now made. It is still though a bit outdated.
1372 * The JOIN notify type now takes one extra argument <Channel ID>.
1373 The packet used to be destined to the channel but now the
1374 JOIN type may be sent as list thus it is impossible to
1375 destine it to any specific channel. By adding this argument
1376 it is again possible.
1378 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Added CREDITS file. The CHANGES and CREDITS file will appear
1381 in the distribution as well.
1383 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1386 types in the server's silcd/packet_receive.c.
1388 * Implemented CMODE and CUMODE to work in router environment.
1390 * Fixed minor encoding and decoding buglet from the
1391 lib/silccore/silcmode.c.
1393 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1396 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1398 * Changed all SilcConfigServer* and silc_config_server* to
1399 SilcServerConfig* and silc_server_config*, respectively.
1402 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1404 * Associated the ID (client or server ID) to the Authentication
1405 Payload to avoid any possibility of forging. Updated the
1406 protocol specification and the code accordingly.
1408 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * The RSA key length is now save to the RsaKey context in the
1411 key generation process in lib/silccrypt/rsa.c. The key length
1412 is now used to figure out the maximum size of the block allowed
1413 to be encrypted/signed.
1415 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1416 is equivalent to the silc_mp_mp2bin but does not allocate any
1419 * Changed silc_mp_mp2bin API to take length argument. If it is
1420 non-zero then the buffer is allocated that large. If zero, then
1421 the size is approximated using silc_mp_sizeinbase, which however
1424 * Created Global RNG API which is global RNG that application can
1425 initialize. After initializing, any routine anywhere in the
1426 code (including library) can use RNG without allocating a new
1427 RNG object. This was done to allow this sort of use of the
1428 RNG in code that has no chance to allocate RNG object. All
1429 applications currently allocate this and many routines in the
1430 library use this. Affected file lib/silccrypt/silcrng.[ch].
1432 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1433 it to use the Global RNG API.
1435 * Defined Authentication Payload into protocol specification that
1436 is used during SILC session to authenticate entities. It is
1437 used for example by client to authenticate itself to the server
1438 to obtain server operator privileges.
1440 Implemented this payload into the lib/silccore/silcauth.[ch].
1441 Implemented also routines for public key based authentication
1442 as the new protocol specification dictates.
1444 Moved definitions of different authentication methods from
1445 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1447 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1448 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1449 silc_pkcs_verify_with_hash functions into the file
1450 lib/silccrypt/silcpkcs.[ch].
1452 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * The client entry's userinfo pointer must be always valid.
1455 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1456 will fail since it requires the userinfo. Now, the userinfo
1457 is allocated as "" if actual userinfo does not exist. Actually,
1458 it must exist and it is totally Ok to drop client connections
1459 that does not announce the userinfo. However, we will make
1460 this workaround for now.
1462 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1463 to return the remote port by socket.
1465 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1468 SILC_SERVER_PENDING_EXEC and added an new macro
1469 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1470 data or when error occurs while processing the pending command.
1472 Added new argument `destructor' into silc_server_command_pending
1473 and to the SilcServerCommandPending object. This destructor is
1474 now called after calling the pending callback or if error occurs
1475 immediately. If error occurs the actual pending callback won't
1476 be called at all - only the destructor. The destructor may be
1477 NULL if destructor is not needed.
1479 All this applies for client library code as well. Similar
1480 changes were made there as well for the pending commands.
1482 In the client, the application must now allocate the
1483 SilcClientCommandContext with the silc_client_command_alloc
1486 * Added reference counter to the SilcServerCommandContext. Added
1487 function silc_server_command_alloc and silc_server_command_dup
1490 Same type of functions added to the client library for the same
1493 * Removed the cmd_ident from IDListData away since it is now
1494 global for all connections. It is the command identifier used
1495 in command sending and with pending commands. The affected file
1498 * Added reference counter to the SilcSocketConnection objecet to
1499 indicate the usage count of the object. The object won't be
1500 freed untill the reference counter hits zero. Currently only
1501 server uses this, and client ignores it. The client must be
1502 set to use this too later. The affected files are
1503 lib/silccore/silcsockconn.[ch]. Added also the function
1504 silc_socket_dup to increase the reference counter.
1506 This was mainly added because it is possible that the socket
1507 is removed underneath of pending command or other async
1508 operation. Now it won't be free'd and proper DISCONNECTING
1509 flags, etc. can be set to avoid sending data to connection that
1510 is not valid anymore.
1512 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1513 the connection. After that it sets SILC_SET_DISCONNECTED.
1514 It is, however, possible that the socket data is not still freed.
1515 The silc_server_packet_process now checks that data is not
1516 read or written to connection that is DISCONNECTED. The socket
1517 get's freed when the reference counter hits zero.
1519 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Changed the client operation API: channel_message operation's
1522 `sender' is now the client entry of the sender, not the nickname
1523 and the `channel' is the channel entry, not the channel name.
1525 In the private_message operation the `sender' is now also the
1526 client entry of the sender not the nickname.
1528 Affected file is lib/silcclient/ops.h and all applications
1529 using the client operations.
1531 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Moved the calling of ops->connect() from connect_to_server_final
1534 into receive_new_id functin since that is the point when the
1535 client is actually allowed to send traffic to network. The
1536 affected file is lib/silcclient/client.c.
1538 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1541 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1542 (if needs broadcasting) instead of broadcasting the packets one
1543 by one which would make a burst in the network traffic.
1545 * Added `broadcast' argument to the functions in silcd/server.[ch]
1546 silc_server_create_new_channel[_with_id] to indicate whether
1547 to send New Channel packet to primary router.
1549 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added new function into the silcd/server.[ch] files:
1552 silc_server_create_new_channel_with_id to create new channel with
1553 already existing Channel ID.
1555 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1556 lib/silccore/silcpacket.h. This packet is used t send list of
1557 Set Mode payloads inside one packet. Server uses this to set
1558 the modes for the channels and clients on those channels, that it
1559 announced to the router when it connected to it. The protocol
1560 specification has been updated accordingly.
1562 * The silc_server_new_channel did not handle the packet coming
1563 from normal server as it normally does not send that. However,
1564 when it announces its channels it does send it. Implemented
1565 the support for that.
1567 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1568 into the file lib/silccore/id.h.
1570 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1572 * Fixed memory leaks in the functions silc_idlist_del_client,
1573 silc_idlist_del_channel and silc_idlist_del_server in the file
1574 silcd/idlist.c. All of those leaked like a sieve.
1576 * Fixed some small memory leaks in the client's function
1577 silc_client_notify_by_server.
1579 * Added functions into silcd/server.c: silc_server_announce_clients,
1580 silc_server_announce_channels and silc_server_announce_server.
1581 These functions are used by normal and router server to announce
1582 to its primary router about clients, channels and servers (when
1583 router) that we own. This is done after we've connected to the
1586 These functions effectively implements the following packet types:
1587 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1588 and SILC_PACKET_NEW_ID_LIST.
1590 * Added new functions into the silcd/packet_receive.[ch]:
1591 silc_server_new_id_list, silc_server_new_channel_list and
1592 silc_server_new_channel_user_list to handle the incoming
1593 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1595 * Added support of changing Channel ID in the function
1596 silc_server_replace_id. If the server that announces a channel
1597 to the router already exists in the router (with same name but
1598 with different Channel ID), router is responsible to send
1599 Replace ID packet to the server and force the server to change
1600 the Channel ID to the one router has.
1602 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1603 client that the Channel ID has been changed by the router. The
1604 normal server sends this to the client. Client must start using
1605 the new Channel ID as the channel's ID.
1607 Implemented handling of this new type into lib/silcclient/client.c
1608 into the function silc_client_notify_by_server.
1610 * Added new function silc_idlist_replace_channel_id into the files
1611 silcd/idlist.[ch] to replace the Channel ID.
1613 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Call silc_server_command_identify_check always when processing
1616 the IDENTIFY command in silcd/command.c
1618 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1621 send keepalive packets. The packet can be sent by clients,
1622 servers and routers.
1624 Added function silc_socket_set_heartbeat into the file
1625 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1626 If not set, the heartbeat is not performed. The actual
1627 heartbeat is implemented in the low level socket connection
1628 library. However, application is responsible of actually
1631 Added silc_server_send_heartbeat to send the actual heartbeat
1632 packet into silcd/packet_send.[ch]. Server now performs
1633 keepalive with all connections.
1635 * Added silc_task_get_first function into lib/silcutil/silctask.c
1636 to return the timeout task with shortest timeout. There was a bug
1637 in task unregistration that caused problems. TODO has been
1638 updated to include that task system must be rewritten.
1640 * The client library will now resolve the client information when
1641 receiving JOIN notify from server for client that we know but
1642 have incomplete information.
1644 * Rewrote parts of silc_server_remove_from_channels and
1645 silc_server_remove_from_one_channel as they did not remove the
1646 channel in some circumstances even though they should've.
1648 * Encryption problem encountered in server:
1650 The LEAVE command used to send the Channel Key packet to the
1651 router immediately after generating it. However, the code
1652 had earlier sent Remove Channel user packet but not immediately,
1653 ie. it was put to queue. The order of packets in the router
1654 was that Channel Key packet was first and Remove Channel User
1655 packet was second, even though they were encrypted in the
1656 reverse order. For this reason, MAC check failed. Now, this
1657 is fixed by not sending the Channel Key packet immediately but
1658 putting it to queue. However, this is more fundamental problem:
1659 packets that are in queue should actually not be encrypted
1660 because packets that are sent immediately gets encrypted
1661 actually with wrong IV (and thus MAC check fails). So, packets
1662 that are in queue should be encrypted when they are sent to
1663 the wire and not when they put to the queue.
1665 However, the problem is that the current system has not been
1666 designed to work that way. Instead, the packet is encrypted
1667 as soon as possible and left to the queue. The queue is then
1668 just purged into wire. There won't be any fixes for this
1669 any time soon. So, the current semantic for packet sending
1672 o If you send packet to remote host and do not force the send
1673 (the packet will be in queue) then all subsequent packets to the
1674 same remote host must also be put to the queue. Only after the
1675 queue has been purged is it safe again to force the packet
1678 o If you send all packets immediately then it safe to send
1679 any of subsequent packets through the queue, however, after
1680 the first packet is put to queue then any subsequent packets
1681 must also be put to the queue.
1683 Follow these rules and everything works fine.
1685 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Added new function silc_server_remove_clients_by_server to
1688 remove all client entries from ID list when the server connection
1689 is lost. In this case it is also important to invalidate all
1690 client entires as they hold the invalid server entry. This
1691 fixes fatal bug when server has lost connection and will reconnect
1694 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Made some sanity checks to silc_server_daemonise like to check
1697 whether the requested user and group actually exists.
1699 * Added sanity check to SKE's silc_ske_responder_finish to check
1700 that the public and private key actually is valid.
1702 * Invalidate the client's nickname when receiving Replace ID
1703 packet and the Client ID is being replaced. This means that the
1704 server will query the nickname if someone needs it (client)
1707 * Sort the ID Cache in client library when the ID Cache data
1708 has changed (needs sorting).
1710 * Do not allow for SILC client to create several connections to
1711 several servers. The client does not support windows right now
1712 and generating multiple connections causes weird behaviour.
1714 Irssi-silc client does support windows and can handle several
1715 connections without problems, see: www.irssi.org and SILC plugin.
1717 * Fixed some places where client was added to the IDList. The
1718 rule of thumb is following (in order to get everything right):
1719 If the client is directly connected local client then the
1720 `connection' argument must be set and `router' argument must be
1721 NULL to silc_idlist_add_client function. If the client is not
1722 directly connected client then the `router' argument must
1723 bet set and the `connection' argument must be NULL to the
1724 silc_idlist_add_client function.
1726 * The funtion silc_server_packet_send_local_channel actually did
1727 not check whether the client was locally connected or not. It
1728 does that now. Fixed a bug related to LEAVE command.
1730 * Fixed Remove Channel User payload parsing bug in server's
1731 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1733 * The server's silc_server_save_channel_key now checks also the
1734 global ID list for the channel as it might not be in the local
1735 list. Fixed a bug related to LEAVE command.
1737 * Is this the end of the [<unknown>] buglet that has been lurking
1738 around for a long time? A little for loop fix in server's
1739 silc_server_command_whois_parse that is used by both IDENTIFY
1740 and WHOIS command. At least, this was a clear bug and a cause
1741 of one type of [<unknown>] buglet.
1743 * WHOIS and IDENTIFY commands call the function
1744 silc_server_command_[whois/identify]_check function even if
1745 we are not router server.
1747 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * Added --with-gmp configuration option. If set the GMP
1750 is always compiled in the SILC source tree. If not set then
1751 it is checked whether the system has the GMP3 installed. If
1752 it has then the GMP won't be compiled (the system's headers
1753 and library is used), if it doesn't have it then the GMP is
1754 compiled in the SILC source tree.
1756 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Changed RSA private exponent generation to what PKCS #1
1759 suggests. We try to find the smallest possible d by doing
1760 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1761 not security fix but optimization.
1763 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Added new config entry [Identity] to fork the server and run
1766 it as specific user and group. A patch from Bostik.
1768 * Imported Dotconf configuration library into lib/dotconf.
1769 This will be used to create the SILC configuration files later.
1770 It will appear in the distsribution after this commit.
1772 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * A big code auditing weekend happening. Auditing code for
1775 obvious mistakes, bugs and errors. Also, removing any code
1778 Removed files for being obsolete:
1780 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1781 inline in the file lib/silcutil/silcbuffer.h)
1783 o lib/silcutil/silcbufutil.c (the header has inline versions)
1785 Changed code to fix possible error conditions:
1787 o The buffer formatting routines now check that the destination
1788 buffer really has enough space to add the data. This applies for
1789 both buffer formatting and unformatting
1790 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1791 unformatting was changed to accomodate following rules:
1792 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1793 sent to the function while XXX_*STRING will not allocate or copy
1794 the data into the buffer. Instead it sets the pointer from the
1795 buffer into the pointer sent as argument (XXX_*STRING used to
1796 require that the pointer must be allocated already). This change
1797 makes this whole thing a bit more consistent and more optimized
1798 (note that the data returned in the unformatting with XXX_*STRING
1799 must not be freed now). The routines return now -1 on error.
1801 o Tried to find all code that use buffer_format and buffer_unformat
1802 and added return value checking to prevent formatting and
1803 especially unformatting errors and possible subsequent fatal
1806 o Changed ske->x and ske->KEY to mallocated pointers in
1807 lib/silcske/silcske.h. Fixed possible data and memory leak.
1809 o Added return value checking to all *_parse* functions. Fixed
1810 many memory leaks as well.
1812 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1813 so that buffer overflows would not happen. All code now also
1814 checks the return value as it can fail.
1816 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added reconnection support to server if the normal server looses
1819 its connection to the router (for example if router is rebooted).
1820 The server performs normal reconnection strategy implemented
1821 to the server. Affected file silcd/server.c.
1823 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Added new packet type SILC_PACKET_SET_MODE that is used to
1826 distribute the information about changed modes (for clients,
1827 channels and clients channel modes) to all routers in the
1828 network. Updated the protocol specification accordingly.
1830 Added functions into silcd/packet_send.c and
1831 silcd/packet_receive.c: silc_server_send_set_mode,
1832 silc_server_set_mode.
1834 Added new files silcmode.[ch] into lib/silccore that implements
1835 the encoding and decoding of Set Mode Payload. Added new type
1836 SilcSetModePayload. Moved the definitions of different modes
1837 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1839 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Oops, a little mistake in server's connection authentication
1842 protocol. The protocol is not ended with FAILURE but with
1843 SUCCESS if the authentication is Ok. :) Affected file is
1846 * Implemented NICK_CHANGE notify handling in server in the file
1847 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1848 the local clients on the channel. After the changing nickname
1849 in router environment snhould work and the [<unknown>] nickname
1850 should appear no more.
1852 The silc_server_replace_id function that receives the Replace ID
1853 payload now sends the NICK_CHANGE notify type also in the file
1854 silcd/packet_receive.c
1856 * Changed WHOIS and IDENTIFY command to support the maximum amount
1857 of arguments defined in protocol specs (3328 arguments). This
1858 fixed a bug that caused problems when there were more than three
1861 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * Added extra parameter, command identifier, to the
1864 silc_client_send_command so that explicit command identifier
1867 Changed that ID list routines uses specific command identifier
1868 when sending WHOIS/IDENTIFY requests to the server so that they
1869 can be identified when the reply comes back.
1871 Affected files lib/silcclient/command.[ch],
1872 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1874 * Added `sender' argument to silc_server_packet_send_to_channel
1875 to indicaet the sender who originally sent the packet to us
1876 that we are now re-sending. Ignored if NULL. Affected file
1877 silcd/packet_send.[ch].
1879 * Added some server statistics support in silcd/server_internal.h
1880 SilcServerStatistics structure and around the server code. Also
1881 send some nice statistics information when client is connecting
1884 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Fixed channel ID decoding in server's JOIN command reply in
1887 silcd/command_reply.c
1889 * Fixed braodcasting of replace ID payload to not to send it if
1890 we are standalone server in silcd/packet_receive.c.
1892 * Fixed all channel message sending routines to not to send
1893 packets to clients that has router set, since they are routed
1894 separately in the same function earlier. Affects file
1895 silcd/packet_send.c and all channel packet sending functions.
1897 * In USERS reply, res_argv[i] are not allocated, the table
1898 is allocated. Thus changed that free the table, not its
1901 * In server's whois_check and identify_check if the client is
1902 locally connected do not send any WHOIS commands - they are not
1905 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * Fixed some minor bugs in client when sending WHOIS command. The
1908 arguments was in wrong order.
1910 * Removed statis function add_to_channel from server in
1911 silcd/command.c that was previously used with the joining but
1914 * Tested USERS command in router environment successfully with two
1915 routers, two servers and two clients.
1917 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Reorganized the USERS command and command reply in client library
1920 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1921 When the command is given by user we register a pending command
1922 callback that will reprocess the command after the reply has been
1923 received from the server. When reprocessing the packet we then
1924 display the information. Thus, the USERS information is displayed
1925 now in the command callback instead of in the command reply
1926 callback. The processing of the command is same as previously
1927 when server has sent the command reply in the JOINing process.
1929 * Added to USERS command in silcd/command_reply.c to join the client,
1930 we didn't use to know about, to the channel after we've created
1931 a client entry for it. Also, for clienet we did know already still
1932 check whether it is on the channel or not and add it if not.
1934 * Removed silc_server_command_join_notify as the function and its
1937 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Changed the client's pending command handling to the same as the
1940 server's pending command handling. It is also now possible to
1941 execute command reply functions from other command reply
1942 function as the function callbacks for commands and command
1943 replies are one and same. The pending commands are not static
1944 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1945 in client connection context. Thus, pending commands are server
1946 connection specific as it is convenient.
1948 Changed the function silc_client_command_pending and
1949 silc_client_command_pending_del and added new function
1950 silc_client_command_pending_check. Removed the
1951 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1954 * Added cmd_ident, current command identifier, to the client
1955 connection context in lib/silcclient/client.h to keep track on
1956 command identifiers used in command sending. Client's command reply
1957 function handling now supports the mandatory command identifiers.
1959 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1960 funtions in client to fully support pending command callbacks.
1962 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1963 as one of the arguments to the application in the command reply
1966 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1967 before first releasing SILC but came back. Now it is removed again
1968 and should come back nomore. The FORWARDED flag was used only
1969 by the JOINing procedure by forwarding the command packet to router.
1970 Now, the JOINing procedure has been changed to more generic (due
1971 to various router environment issues) and FORWARDED is not needed
1972 anymore for anything. The protocol specification is yet to be
1975 Now, removed silc_server_packet_forward from server and the flag
1976 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1978 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Renamed NAMES command to USERS command. The NAMES was named that
1981 due to historical reasons. Now it is renamed. Also, rewrote
1982 parts of the USERS command. The nickname list is not sent anymore
1983 by the server. Only Client ID and mode lists are sent in the USERS
1984 command. Changed this also to the protocol specification.
1986 The client now resolves the names and stuff after it receives
1987 the USERS list from the server when joining to the channel.
1989 * WHOIS and IDENTIFY commands has been changed to support multiple
1990 Client ID's per command. One can now search for multiple users
1991 in the network by sending only one WHOIS or IDENTIFY command.
1992 Changed the code and the protocol specifications.
1994 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1995 uses silc_server_command_whois_parse to parse the request. */
1997 * If normal server, do not parse the WHOIS and IDENTIFY requests
1998 before sending it to the router. Saves some time.
2000 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Fixed JOIN command on client library. Wrong number of arguments
2003 used to crash the client.
2005 * Added silc_server_channel_has_global function to check whether
2006 channel has global users or not.
2008 * Added silc_server_channel_has_local function to check whether channel
2009 has locally connected clients on the channel.
2011 * The silc_server_remove_from_one_channel now checks whether the
2012 channel has global users or not after given client was removed from
2013 the channel. It also checks whether the channel has local clients
2014 on the channel anymore. If it does not have then the channel entry
2015 is removed as it is not needed anymore.
2017 * The silc_server_notify now checks on JOIN notify whether the joining
2018 client is one of locally connected or global. If it is global then
2019 the channel has now global users on the channel and that is marked
2020 to the channel entry. Also, it now saves the global client to
2021 global list who is joining and JOINs it to the channel. This is
2022 for normal server, that is.
2024 Changed silc_server_send_notify_on_channel,
2025 silc_server_packet_relay_to_channel and
2026 silc_server_packet_send_to_channel check if we are normal server
2027 and client has router set (ie. global client) do not send the
2028 message to that client, as it is already routed to our router.
2030 * Implemented LEAVE notify type handling in silc_server_notify
2033 * Tested LEAVE command in router environment successfully. Tested
2034 with two routers, two servers and two clients.
2038 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2040 * Implemented SIGNOFF notify type handling in silc_server_notify
2043 * silc_server_remove_id now removes the client entry from all channels
2044 it has joined and thusly sends SIGNOFF notify type.
2046 * Rewrote the NAMES list generation in server by removing two excess
2047 loops. The lists are created now inside one loop.
2049 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2051 * silc_server_remove_channel_user checks now also global list
2052 for channel and client.
2054 * silc_server_new_channel_user checks now both local and global
2055 list for channel and client. Fixed a bug in client id decoding.
2056 Used to decode wrong buffer.
2058 * silc_server_channel_message checks now both local and global
2059 list for channel entry.
2061 * Tested channel joining (hence JOIN) in router environment
2062 successfully. Tested with two routers, two servers and two
2065 * Tested channel message sending in router environment successfully.
2067 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Added silc_server_save_channel_key into server.[ch] to save the
2070 received channel key in Channel Key payload processing. It is
2071 also used in JOIN command reply handling.
2073 Equivalent function silc_client_save_channel_key added into
2074 client.[ch] into client library.
2076 * Changed JOIN command reply to send information whether the channel
2077 was created or not (is existing already) and the channel key
2078 payload. Changed protocol specs accordingly.
2080 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2081 the request was sent by ID and not by nickname. Crashed on
2084 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2087 now correctly save the received data.
2089 * silc_server_free_sock_user_data now notifies routers in the
2090 network about entities leaving the network.
2092 At the same time implemented functions silc_server_remove_id
2093 and silc_server_send_remove_id to receive and send REMOVE_ID
2094 packets. The packet is used to notify routers in the network
2095 about leaving entities. The ID removed will become invalid in
2098 * Added function silc_idlist_del_server into server. Removes and
2099 free's server entry from ID list.
2101 * silc_server_private_message function now checks, if we are router,
2102 that the destination ID really is valid ID, naturally.
2104 * In router when NEW_ID packet is received (for new client) the
2105 hash of the Client ID is saved in the ID Cache but the
2106 client->nickname is set to NULL, instead of putting the hash
2109 IDENTIFY command now also checks that client->nickname must be
2110 valid. If it is not if will request the data from the server who
2111 owns the client. Added new function
2112 silc_server_command_identify_check.
2114 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2115 to set the command to already allocated Command Payload.
2117 * Tested private message sending in router environment with two
2118 routers, two servers and two clients. Fixed minor bugs and now
2121 * Fixed segfault from client's NAMES command. Used to crash if
2124 * Forwarded packets must not be routed even if it is not destined
2125 to the receiver. Changed server code comply with this.
2127 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Added `require_reverse_mapping' boolean value to ServerParams
2130 structure. If TRUE (not default) the server will require that
2131 the connecting host has fully qualified domain name.
2133 If the reverse mapping is not required and hostname could not be
2134 found the IP address is used as hostname.
2136 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Implemented version string checking to both client and server.
2139 The check is incomplete currently due to the abnormal version
2140 strings used in development version of SILC.
2142 * Changed all command functions in server to use the new
2145 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Changed char *data to unsigned char *data in ID Cache system to
2148 support binary data as ID Cache data. Changed code to support
2149 binary data in lib/silccore/idcache.c.
2151 * Renamed silc_server_packet_relay_command_reply to
2152 silc_server_command_reply as it is normal packet receiving
2153 function. Rewrote the function to accept command replys for
2154 servers and not only for clients.
2156 * Mark remote router always as registered server if we are connecting
2157 to it. Otherwise, commands sent by the router to us are ignored.
2159 * All ID List find routines now returns the ID Cache Entry pointer
2160 as well if requested.
2162 * WHOIS command works now in router environment, tested with two
2163 routers, two servers and two clients.
2165 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2166 in router environment (as it is almost equivalent to WHOIS) but
2167 hasn't been tested thoroughly. Added new functions:
2169 silc_server_command_identify_parse
2170 silc_server_command_identify_send_reply
2171 silc_server_command_identify_from_client
2172 silc_server_command_identify_from_server
2174 * Disabled route cache adding because adding two different ID's with
2175 same IP replaces the old cache entry thus giving wrong route.
2176 The entry->router->connection is always the fastest route anyway
2177 so route cache may not be needed. Of course, new routes maybe
2178 established after receiving the ID when the entry->router->connection
2179 might not be anymore the most optimal.
2181 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Add route cache for received ID for fast routing.
2185 * Added silc_server_packet_route to route received packet on router
2186 that is not destined to us.
2188 * Renamed silc_server_get_route to silc_server_route_get.
2190 * Added id_string and id_string_len fields into SilcServer to
2191 include encoded ServerID for fast comparing without excess
2192 encoding of the ID's.
2194 * Cleaned up WHOIS command on server side. Added following static
2197 silc_server_command_whois_parse
2198 silc_server_command_whois_check
2199 silc_server_command_whois_send_reply
2200 silc_server_command_whois_from_client
2201 silc_server_command_whois_from_server
2203 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2204 arguments in command replies. All command functions should be
2205 updated to use this macro.
2207 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Minor typo fixes on command reply handling on server.
2211 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Added silc_server_command_add_to_channel internal routine to add
2214 the client to the channel after router has created the channel and
2215 sent command reply to the server.
2217 * Added generic silc_server_send_command to send any command from
2220 * Use static buffer with ID rendering instead of duplicating data.
2222 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Fixed a channel user mode bug when joining to a channel server gave
2225 everybody channel founder rights, oops.
2227 * We mark ourselves as the router of the incoming server connection
2228 if we are router ourselves. This way we can check in some packet
2229 sending functions whether it is locally connected server. For
2230 incoming router connections we put NULL.
2232 * For router sending packets locally means now always sending the
2233 packet cell wide; to local clients and local servers. For normal
2234 server sending packet locally means sending it to only local
2237 * Fixed the JOIN command to really work in router environment. If the
2238 channel is created it is always created by the router. Router is
2239 also responsible of making the initial joining to the channel,
2240 sending JOIN notify to the sending server and distributing
2241 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2242 does not exist server doesn't do anything else but forward the
2243 command to the router which performs everything.
2245 * Added silc_server_send_channel_key function to send the Channel Key
2248 * Added silc_server_create_channel_key to create new channel key. The
2249 channel key is now re-generated everytime someone joins or leaves
2250 a channel, as protocol dictates. Note: channel->key_len is the
2253 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2256 packet_receive.[ch] to separate packet sending and receiving
2257 routines. The server.[ch] now includes everything else including
2258 actual packet processing (writing and reading data) and other
2261 Renamed silc_server_private_message_send_internal to
2262 silc_server_send_private_message. The routine is still though
2263 used only to relay private messages as server does not send
2264 private messages itself.
2266 Renamed silc_server_new_channel to silc_server_create_new_channel
2267 and added new function sicl_server_new_channel that handles the
2268 incoming New Channel packet. Added also new sending function
2269 silc_server_send_new_channel to send New Channel Payload.
2271 * Added new function silc_server_notify to process incoming notify
2272 packet to the server/router. Server may then relay the notify
2273 to clients if needed.
2275 * Added new function silc_server_new_channel_user to process incoming
2276 New Channel User packet. Router will redistribute the packet and
2277 send JOIN notify to its local clients and locally connected servers
2278 if needed. Normal server will send JOIN notify to its local client
2279 on same channel when received this packet. Added also corresponding
2280 sending function silc_server_send_new_channel_user to sent the
2283 * Added boolean route argument to send_notif_to_channel and
2284 packet_send_to_channel functions to attempt to route the packet
2285 if it is TRUE and send only locally if it is FALSE.
2287 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * silc_server_replace_id now broadcasts the received replace ID
2290 packet if it is not broadcast packet already. The router must
2291 broadcast to inform other routers about changed ID.
2293 * Added backpointer to server's router into SilcServer context in
2294 silcd/server_internal.h.
2296 * Fixed silc_server_packet_broadcast to send correct broadcast
2299 * The channel key is now distributed to the local client as soon
2300 as it is received from the router (in router environment) so that
2301 no other packet may be sent for the channel until client has
2304 * silc_server_remove_channel_user now broadcasts the received
2305 Remove Channel User packet if it is not broadcast packet already.
2306 The router must broadcast to inform other routers about removed
2309 * Added users field into SilcPacketContext that is a reference count
2310 of the context. One can increase the reference count by calling
2311 silc_packet_context_dup which is now changed to just increase the
2312 reference count instead of duplicating the data. The reference
2313 count is decresed by calling silc_packet_context_free that will
2314 free the data after the reference count hits zero.
2316 For now on the packet context and everything allocated into it
2317 (including the raw packet from network) must be freed by calling
2318 the new silc_packet_context_free function. Added also new function
2319 silc_packet_context_alloc that must be used now to allocate the
2320 context. This also means that if a routine is asynchronous from
2321 silc_[client/server]_packet_parse_type the packet context must
2322 be duplicated by calling silc_packet_context_dup. Otherwise it
2323 gets free'd after silc_[client/server]_packet_parse_type returns.
2324 Also, one must remember that if packet is duplicated then its
2325 reference count must be decresed by calling the free function as
2326 many times as it was duplicated.
2328 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2329 from both client and server.
2331 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Made joining to a channel working in router environment.
2335 * Cleaned up JOIN command on server side and create function
2336 silc_server_command_join_channel internal routine to make the
2339 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Changed silc_command_pending list to SilcDList. Also, added
2342 `ident' field to SilcServerCommandPending structure to identify
2343 the reply and to call correct callback.
2345 Added silc_server_command_pending_check function to replace the
2346 corresnponding macro. The silc_command_pending list is not
2349 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2350 to set identifier to previously allocated Command Payload. It
2351 is used to set identifier for command when resending Command
2354 * Added silc_command_payload_encode_payload to encode Command
2355 Payload buffer from SilcCommandPayload structure.
2357 * Added silc_argument_payload_encode_payload to encode Argument
2358 payload buffer from SilcArgumentPayload structure.
2360 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Changed WHOIS command to support router connection on server side.
2363 The whois request is always sent to router unless the server is
2364 standalone server. After server has received the reply from the
2365 router will it send the reply to the client.
2367 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2368 broadcast received broadcast packet. The function is used only
2369 by router. The broadcast packet is always sent to the router's
2372 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2373 render given ID to printable string, for log files for example.
2375 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Made basic router to router connections working. At least they
2378 can now connect to each other but nothing really works the way
2379 they are supposed - yet.
2381 * Added new initiator token to RouterConnection configuration
2382 file in silcd/serverconfig.[ch]. It is used to tell whether we
2383 are the initiator to the remote router or whether we'll expect
2384 the other end to connect.
2386 * Moved registering of listener task to silc_server_init, hence
2387 the server starts listenning as soon as it is run, even if it
2388 does not have connections to other routers. Let's see how well
2391 * Changed default connection retry timeouts for more suitable in
2394 * Removed cipher and such arguments from silc_idlist_add_client
2395 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2396 Added new function silc_idlist_add_data to add the keys and stuff
2399 * Added SilcIDListData structure and added it to SilcClientEntry
2400 and SilcServerEntry as their first field in the structure. This
2401 way we can explicitly cast the ID entries to the SilcIDListData
2402 structure and get common data for the entries. In past, we had
2403 to first check what type of connection it is and then cast it to
2404 correct ID entry type. Now, we can directly cast the opaque
2405 pointer to the SilcIDListData (no matter what ID entry it actually
2406 is) and get the data needed.
2408 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2411 in some circumstances even if threre were timeout tasks, though not
2412 IO tasks, but tasks anyway. Now fixed.
2414 * Defined SilcServerConnection structure to hold connection specific
2415 stuff about directly connected servers and routers. The definition
2416 is currently in silcd/server_internal.h. I thought about having
2417 a bit more important role fro this struct but for now it is used
2418 only when connecting to other server (or router actually).
2420 * Added connecting retry support in server when connecting to
2421 router(s). The retry feature implement exponential backoff
2422 algorithm. Also, added SilcServerParams structure to hold default
2423 parameters for server. For now, it include these retry settings
2424 and are hard coded. After server is moded to be as Silc Server
2425 Library this structure will be more important.
2427 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Changed client librarys channel->clients table to SilcList and
2430 changed code accordingly.
2432 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Changed client's channel table to SilcList and changed code
2435 accordingly. Also changed SilcChannelClientEntry to include back-
2436 pointer to the channel so that client entry can use that structure
2437 as list as well and we have fast cross-reference to the channel.
2438 This change dramatically decreased the complexity of channel
2439 handling with client entry and vice versa (removed one extra
2440 loop when searching for channel entry from many functions).
2442 * Changed server->sim from table to SilcDList and changed code
2445 * NAMES command can now be used from user interface. It will show
2446 the user list on the channel, neatly.
2448 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2449 Code now saves realname of the user if it becomes available.
2451 * Renamed configure.in to configure.in.pre and made ./prepare
2452 script to automatically add correct version string to
2453 configure.in which it creates from configure.in.pre.
2455 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * NAMES command reply now shows users mode with the nickname when
2460 * Moved silc_client_ch[u]mode[_char] functions from
2461 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2462 place sucks, they are utility functions and should be in some
2465 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2467 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2470 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Added TRQ (efficient deque and list library) into lib/trq. This is
2475 a very good list library that is currently used in the SILC. Defined
2476 SilcList API over the library because I didn't like the API very
2477 much. See lib/trq/silclist.h for the API and examples of how to
2478 use the API. Fixed various places in the code to use the new
2479 SilcList API. The SilcList is meant for lists that has a structure
2480 already defined as a list. It is not suitable to add just some
2481 context to the list (in TRQ, the context is the list actually).
2483 So, I defined SilcDList that can be used for the purpose where
2484 predefined list structure does not exit. This can be used as
2485 such list. Now some context just can be added to the SilcDList.
2486 Currently this list is not used in the SILC just yet, though there
2487 are a lot places where this can replace dynamically allocated
2488 tables and I will fix these places, later, to use SilcDList.
2489 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2490 and use TRQ internally).
2492 Also fixed some annoying warning messages that the original TRQ
2493 code generated. Also minor changes to TRQ's Makefile.in.
2495 * Added support for querying by Client ID to both WHOIS and
2496 IDENTIFY commands into server, as required by the protocol.
2498 * Removed method function pointers from SilcBuffer structure. They
2499 weren't used to anything and just increased the context size for
2500 no good reason. This change also made silc_buffer_alloc and
2501 silc_buffer_free functions inline functions.
2503 * Disabled command flooding detection support until it's fixed so
2504 that it accepts commands in but does not execute them more than once
2507 * Added silc_net_localhost(), to return local hostname, into
2508 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2509 that must be initialized before calling silc_client_init.
2511 * Added new function: silc_server_send_notify_on_channels to send
2512 notify messages to all channels client has joined. It is assured
2513 that the message is sent only once per client.
2515 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2516 lib/silcutil/silcutil.[ch] as silc_format function. The new
2517 function is generic and is used by server as well, not only by
2518 the logging routines.
2520 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2521 the provided version string was not acceptable. Added new function:
2522 silc_ske_check_version into lib/silcske/silcske.h. The function
2523 must be implemented by the application (client or server) and it
2524 does not reside in the SKE library. The function checks the version
2525 string remote end sent.
2527 * Added back pointers (to opaque context and to SilcSocketConnection)
2528 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2530 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2531 duplicate packet context structure.
2533 * Changed `notify' client operation to send same arguments as client
2534 receives from server except for ID's. ID's are mapped to correct
2535 ID entry and that is returned. Also, if channel entry is not sent
2536 by server but the notify is for channel the channel entry is sent
2537 to application (otherwise application doesn't know that it is for
2538 channel (library gets it from packet's Destination ID)).
2540 * Added silc_client_remove_from_channels into client library to
2541 remove a client from all channels it has joined to. Used when
2542 received SIGNOFF notify from server. Added also new function
2543 silc_client_replace_from_channels to replace old ID entry with
2544 new ID entry on all channels. Used when received NICK_CHANGE
2547 * Fixed ID Cache list handling in silc_idlist_get_client in
2548 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2549 to get (or query) client by ID.
2551 * Updated TODO list.
2553 * Added connection authentication status message defined by the
2554 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2555 support for these into the code in client and server side.
2557 * Added generic function silc_client_send_command to send any command
2558 with variable argument list. Application should use this function
2559 to send commands if the command functions provided by the library
2560 does not suite for the application's user interface needs.
2562 * Added new `failure' client operation. Application is notified about
2563 received failure packet if client is executing a protocol. In this
2564 case the protocol's execution has failed.
2566 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2567 is required by the protocol.
2569 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2570 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2573 * Added status flag to SilcSKE object to indicate realtime status
2574 of the SKE protocol.
2576 * Application receives now exactly same command reply arguments as
2577 the library receives from server. However, if ID is received the
2578 corresponding ID entry is returned to the application (eg. Client
2579 ID is mapped to correct SilcClientEntry entry and that is returned).
2580 Changed command_reply client operation due to this change.
2582 * Changed all ID's in commands and in command replys as ID Payloads.
2583 Change affected both client and server side codes.
2585 All ID's sent in SILC network (with execption of ID's in SILC
2586 Packet header) are sent in ID Payload to support variable length
2589 * Server now notifies nick changes and notifies all clients on
2590 the channels about the new nickname (about the new Client ID,
2593 * Implemented CMODE command to change channel modes. Supports all
2594 channel modes defined by the protocol specs except ban and invite
2595 lists. (Also, private channel key mode is supported but support for
2596 setting private channel key in client is missing, thus, this mode
2597 has no effect on client side (except that server requires that the
2598 client uses private channel key and normal channel traffic does not
2601 Also, invite mode works per se, but INVITE command does not work
2602 yet correctly, so you can set channel as invite only channel but
2603 inviting clients to the channel does not work (it is yet to be
2604 thought what's the best way to do it).
2606 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2607 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2608 Implemented CUMODE command to change user's mode on the channel.
2609 Supports all modes defined by the protocol specs.
2611 * Added NAMES command reply to return users modes on the channel.
2613 * Removed unnecessary and slow ciphers from lib/silccrypt.
2615 * Set SO_KEEPALIVE option to connection sockets by default.
2617 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2619 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2620 redefined the Notify Payload into protocol specs.
2622 * Added silc_id_payload_parse_id to get ID directly from raw
2625 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2628 accept searching by Client ID as well.
2630 * Added support for LEAVE and SIGNOFF notify types in client library.
2632 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2633 to parse ID Payload from raw data.
2635 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Added flags parameter into silc_ske_assemble_security_properties
2638 function in lib/silcske/silcske.[ch].
2640 * Changed notify client operation to fit better for notify messages
2641 sent by server. The notify payload received from server is now
2642 passed to the application (after parsing it to SilcNotifyPayload).
2643 It is application's responsibility to retrieve the arguments
2644 from the payload and show the message the way it wants. The message
2645 sent by server is implementation specific.
2647 * Changed public keys to comply with the protocol specification.
2648 Old public keys are not supported anymore and are not compatible.
2650 * Removed nickname from Channel Payload as the latest draft removed
2651 it. The client must resolve the nickname from the NAMES command
2652 reply received when it joined the channel.
2654 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2656 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Fixed some errors in protocol specification drafts.
2660 * Created lib/silccore/silcnotify.c to implement Notify Payload
2661 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2662 generic payloads described by protocol specifications. The file
2663 includes implementations for ID Payload and Argument Payload.
2665 * Changed Command Payload implementation to use the new Argument
2666 Payload. Changed command_xxxx_payload to command_payload_xxxx
2667 to comply with SILC coding conventions.
2669 * Added suppport for Argument Payload handling in Notify Payload
2670 implementation as protocol requires it. Added the new support
2671 into server and client lib as well.
2673 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Added support for multiple nicknames on same channel. [n] is
2676 added locally to the nickname if there are more than one same
2677 nicknames on the channel.
2679 * Server now sends all nicknames that matched WHOIS request.
2680 Client also shows the list received from server.
2682 * Added TOPIC command to client side. User can now set and show
2683 current topic on channel.
2685 * Added MOTD command to client and server. Also, server sends the
2686 motd when client connects to the server.
2688 * Changed version strings to comply ISO 8601.
2690 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Fixed protocol error handling in client library. It should now
2693 cope even if the SKE fails for some reason.
2695 * Made new protocol specification drafts for submitting to IETF.
2697 * Implemented TOPIC command to server in silcd/command.c.
2699 * Added two new notify types into lib/silccore/silcnotify.h:
2700 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2701 notify nickname change and topic setting/change on a channel.
2703 * API change of command_reply operation in client library. The
2704 application gets now the status type received from server as well.
2706 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2710 * Cras fixed and optimized the packet handling even further and
2711 it should work now. Minor change to the prototype of function
2712 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2714 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Added new function into lib/silcutil/silcschedule.[ch]:
2717 silc_schedule_with_fd to select() a specified fd. The function
2718 returns after timeout expires or data arrives or goes. The
2719 function is used by packet routines to wait that all data is
2720 received from network.
2722 * Fixed data reading from network in lib/silccore/silcpacket.c.
2723 The code now assures that all data is read from the fd and then
2724 continues packet processing. This was a bug fix since the code
2725 used to drop some data in some circumstances.
2727 * Added new function into lib/silcclient/client.[ch]:
2728 silc_client_start_key_exchange to start key exchange after
2729 connection has been established to server. The code internally
2730 now uses this funtion but its main purpose was to provide it
2731 for applications that perform their own connecting. After
2732 application has created a connection it merely calls this
2733 function to start the key exchange between client and server.
2734 The library takes care of everything else after that.
2736 Updated also lib/silcclient/README to explain the usage of
2739 * Do not send to application information that connection has
2740 been established. Application gets notified it by connect
2743 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Applied cras's patch to add silc_schedule_one function. The
2746 function runs scheduler once and returns.
2748 * Fixed the scheduler after cras messed it up. The timeout
2749 handling works now as it's supposed to work.
2751 * Added into lib/silccore/ silcnotify.h to include notify
2752 message types support. Changed silc_server_send_notify*
2753 functions, in server.[ch], to support those new notify types.
2754 Added the support for the notify types into client library,
2755 as well. Added new notify client operation into ops.h in
2758 * Changed silc_server_packet_send_to_channel to send normal
2759 packets instead of just channel message packets. The function
2760 is now used to send the notify packets to channels. It is not
2761 used to send channel message packets anymore, as server never
2764 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2765 va_arg()s as it seems to require it nowadays. I guess, if SILC
2766 is compiled with older va_arg() the new code should work anyway.
2768 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Splitted core library. Core library (lib/silccore) includes
2771 now only SILC protocol specific core (and common) components.
2772 Created new utility library (lib/silcutil) that includes more
2773 generic purpose stuff. The stuff for util library was taken
2774 from the old core library. This was minor and easy split.
2776 * Created SILC Client Library (lib/silcclient) that includes
2777 implementation of the SILC client without user interface. This
2778 was major move from silc/ directory. The code has been changed
2779 so that it is transparent towards the user interface. The
2780 silc/ directory includes now the same user interface as before
2781 and it uses the new client library. Read lib/silcclient/README.
2782 Basicly, the client library performs everything else related
2783 to SILC except user interface handling. Also, configuration
2784 files are considered to be part of user interface and library
2785 does not handle them.
2787 This change also changed a lot of structures, function naming etc.
2788 Most important change was that SilcClientWindow object was
2789 renamed to SilcClientConnection in the client library. Created
2790 also new file lib/silcclient/ops.h. Also added new files
2791 silc/local_command.[ch] and silc/client_ops.[ch].
2793 All these changes were made to make it easier for user interface
2794 designers to create what ever user interface for the SILC client
2797 It is also expected that the server will be moved to lib
2798 directory as well and SILC Server Library will be created;
2799 sometimes in the future.
2801 * Removed Local commands from lib/silccore/silccommand.h as
2802 they are application specific and new client library does not
2803 handle any of those anymore.
2805 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2806 old client implementation in silc/.
2808 * Added support for callback functions in SILC_LOG_* macros.
2809 Application can now set its own callbacks that will be called
2810 instead of using the default functions that will always print
2811 the debug messages to stderr (or stdout). Also, debugging can
2812 now be disabled by setting silc_debug to FALSE and re-enabled by
2813 setting it to TRUE. Note, that logging will still work even
2814 if debugging is disabled.
2816 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2817 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2818 silc_log_reset_debug_callbacks.
2820 * To enable debugging in silc client one must give now -d
2821 option on command line.
2823 * Changed silc_schedule_init to automatically allocate task queues
2824 if they are not allocated before calling it.
2826 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Added GMP 3.1 into math library.
2830 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2833 a channel in SILC network. The packet is used by servers and
2834 routers to notify other routers that user has left a channel.
2835 This little feature was missing until now. Added the feature
2836 to protocol specification as well.
2838 Added functions: silc_server_send_remove_channel_user and
2839 silc_server_remove_channel_user into server.[ch].
2841 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2842 lib/silccore/silcpacket.h. However, they are not implemented
2845 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Fixed joining to a channel and sending channel messages
2848 between server and router. The channel message sending should
2849 now work inside a cell.
2851 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2853 * Fixed the private message sending between server and router.
2854 The private message sending should now work inside a cell.
2856 * Added silc_server_replace_id into server.[ch] to replace
2857 existing ID in the SILC network.
2859 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2860 and silc_idlist_replace_server_id into idlist.[ch] in server.
2862 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Fixed the server to server connections. Server can again now
2865 connect to router. Router to router connections probably does
2868 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Added dynamic protocol registering support. Now protocols can
2871 registered and unregistered on the fly. Patch by cras.
2873 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Added lib/contrib directory to hold routines that some platforms
2876 don't have but are needed by SILC.
2878 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2879 into lin/contrib to provide getopt() and getopt_long() for
2880 those who don't have it.
2882 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Added AWAY command to client. When away message is set and
2885 client receives a private message packet the client automatically
2886 replies to the sender with the away message.
2888 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2889 bug seemed to be the cause of recent problems when compiling
2892 * Added version detection support to SKE protocol specification
2893 and added the new changes to the SKE implementation as well.
2894 There were other minor changes in the SKE protocol as well.
2896 Many changes in lib/silcske/silcske.[ch] and in
2897 lib/silcske/payload.[ch].
2899 * Added ^U functionality, clear input line. Patch from cras.
2901 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Mainly small bugfixes on core library. Fixed some debugging
2904 logging and buffer overflow in silclog.c.
2906 * Updated config.sub and config.guess on the distribution tree.
2908 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added command lagging support in server. Client may execute
2911 commands now only once in two seconds.
2913 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Optimized packet reception. MAC computation and checking is now
2916 also more optimized. A lot previously duplicated code is now
2917 used as generic by both client and server.
2919 * Fixed key pair generation in clientutil.c
2921 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Added into lib/silccore/silcbufutil.[ch] new function;
2924 silc_buffer_realloc.
2926 * Moved generic packet sending/encryption functions to
2927 lib/silccore/silcpacket.[ch] from client and server. Some
2928 rewriting of the functions.
2930 * Moved all generic packet reception/decryption functions to
2931 lib/silccore/silcpacket.[ch] from client and server. The
2932 packet processing is now much cleaner in both client and server.
2933 These were major changes in both client and server.
2935 * Created many common functions in server to do packet sending.
2936 Previously code were duplicated a lot, this has been removed
2939 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Rewrote major parts of the ID cache system. Don't know
2942 whether it is better now or not but at least the API is more
2945 * Major rewrite on ID cache stuff on client because of the ID
2946 cache API changes. Added idlist.c to client.
2948 * Also major rewrite on ID cache stuff on server as well.
2949 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2950 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2951 in hand, instead they are all put into the ID cache system now.
2952 All server_idlist_* routines uses ID cache now instead of
2953 traversing its own lists (those lists does not exist anymore).
2954 SilcIDList though still exists. Also, SilcXXXEntry's are
2957 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Finally made the SKE implementation compliant to the protocol
2960 specification. All mp integers are now binary encoded as
2961 opposed being HEX encoded.
2963 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2966 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2967 functions: silc_[encode/decode]_pem. Also added function
2968 silc_encode_pem_file to PEM encode with newlines ('\n') for
2971 * SILC public keys are now encoded either PEM or binary. Same
2972 option is for private keys as well. By default private keys
2973 are binary encoded and public keys PEM encoded. Silly HEX
2974 encoding were removed.
2976 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2977 function to create fingerprints.
2979 * Fixed a bug in SHA1; does not change the original data anymore.
2981 * Partly implemented INFO command on client and server side.
2982 Fixed CLEAR command. Changes to SERVER command; show current
2983 server(s) when giving command without arguments. Added
2984 VERSION command to client.
2986 * Added check to server that unregistered connections cannot
2987 execute commands (unless it is specificly allowed).
2989 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Fixed screen refresh.
2993 * Fixed channel joining bug from client. On some circumstances
2994 client tried to join to a channel it had already joined.
2996 * Added public key verification process into client's protocol.c.
2997 The client now verifies the public key from user and saves
2998 it into ~./silc/serverkeys/ directory.
3000 Added into: clientutil.[ch]: silc_client_verify_server_key.
3002 * Changed SKE protocol's silc_ske_initiator_finish function
3003 to accept callback function that verifies the received public
3004 key. Removed old silc_ske_verify_public_key function.
3006 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3009 silc_pkcs_private_key[_data]_set.
3011 * Made the password and public authentication more cleaner in
3012 server's protocol.c.
3014 * Removed historic and obsolete protocol `channel_auth' from
3015 both client and server.
3017 * Removed wrong way of sending command status messages from
3018 server to client in server's command.c. The old way violated
3019 protocol specification.
3021 Changes to silccore/silccommand.[ch]: removed
3022 silc_command_encode_status_payload -> not needed anymore,
3023 changed silc_command_encode_payload_va to accept extra
3024 argument on variable argument list. The argument type must
3025 now be provided to the function. Also, added new function:
3026 silc_command_encode_reply_payload_va which is same as
3027 normal command_encode_payload_va except command status type
3028 is provided as extra argument.
3030 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Added ~./silc directory handling. The directory includes the
3033 public and private keys for the client.
3035 Added silc_client_check_silc_dir, silc_client_create_identifier
3036 and silc_client_load_keys.
3038 * Implemented SILC protocol compliant public key. Added public
3039 and private key saving to and loading from files.
3041 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3042 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3043 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3044 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3045 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3047 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3048 silc_pkcs_load_[public/private]_key.
3050 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Added silc_server_get_route (route.[ch]) to get connection
3053 data for the fastest route for given ID.
3055 * Implemented INVITE command on client and server. The command
3056 were re-defined in the SILC Protocol Specification and the
3057 implementation now complies with the specification.
3059 * Implemented PING command on client and server.
3061 * Implemented NAMES command on client and server. The server side
3062 supports currently only normal server not router server yet.
3063 Some changes to NAMES definition in SILC protocol specification.
3065 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Implemented LEAVE command on client and server.
3069 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3070 again. This change was made to the protocol as well. Server
3071 should not violate the protocol specification anymore.
3073 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3076 was tested. SOCKS4 was not but should work anyway.
