1 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4 int64 of at least the xintXX size. If void * is less that 4
5 bytes uint32 * will be used. Defined bool as boolean.
7 * Changed _ALL_ unsigned long and unsigned int to uint32,
8 unsgined short to uint16 in the source tree.
10 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
11 not handle clients that has entry->data.registered == FALSE.
12 They are not in the network anymore. Affected file is
15 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
17 * Implemented the sending of the SERVER_SIGNOFF notify in the
18 server. Affected file is silcd/server.c.
20 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
21 Added also silc_notify_payload_encode_args into the
22 lib/silccore/silcnotify.[ch].
24 * Implemented ther SERVER_SIGNOFF notify handling in the server.
25 Affected file silcd/packet_receive.c.
27 * Implemented the SERVER_SIGNOFF notify handling in the client
28 library. Affected file lib/silcclient/client_notify.c. Also,
29 implemnted the printing of the SERVER_SIGNOFF info to the
30 application. Affected file silc/client_ops.c.
32 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
33 if the deleting was successful. Affected file silcd/idlist.[ch].
35 * Added support for public key authentication in the connection
36 authentication protocol in the client library. Affected file
37 lib/silcclient/protocol.c.
39 * Changed the server's silc_idlist_get_clients_by_* interface
40 to support already allocated array so that new entries may be
41 added to pre-allocated array. Affected file silcd/idlist.[ch].
42 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
45 * All command reply functions in the server now calls the
46 pending command callback even if error occured. This way the
47 error will be delivered to the client as well. Affected files
48 silcd/command.c and silcd/command_reply.c.
50 * Fixed INFO command to return local server's info if no server
51 was provided. Affected file lib/silcclient/command.c.
53 * Removed RESTART command for good. Updated the code and the
56 * Rewrote parts of the task system. It is a bit simpler now.
57 Removed unsued task priorities. The affected files are
58 lib/silcutil/silctask.[ch].
60 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Moved the USERS printing from the library to the application.
63 Affected files lib/silcclient/command.c and silc/client_ops.c.
65 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added channel key re-key support. The re-key is perfomed
70 only by the router and is done once in an hour. Added `rekey'
71 field to the SilcChannelEntry in the server. Affected files
72 silcd/server.c and silcd/idlist.h.
74 * Added silc_task_unregister_by_context into the file
75 lib/silcutil/silctask.[ch].
77 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
79 * Added SILC_UMODE_GONE mode to indicate when the client is not
80 present in the SILC network. Added also support to the local
81 command AWAY that will set this mode. Added support of showing
82 "xxx is gone" in WHOIS command. The USERS command shows the
85 * Fixed setting server and router operator privileges in the
86 server's UMODE command. Affected file silcd/command.c.
88 * Merged the SKE KE1 and KE2 payloads into one payload. The
89 new KE payload is equivalent to the old KE2 payload.
91 Cleaned up the SKE Start Payload parsing. It now uses the
92 simple buffer unformatting to do the parsing. A lot faster
95 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
96 to the SKE that is used to indicate whether both of the SKE
97 parties should perform authentication. By default only the
98 responder performs authentication. By setting this flag also
99 the initiator must do authentication. By default it is unset
100 since in normal SKE case, client to server connection, only
101 the responder should do authentication. When doing SKE between
102 two clients both should perform authentication. Updated the
103 code and the protocol specs.
105 * A little fix to IDENTIFY command in the server. Search the
106 client first by hash not nickname. Affected file is
109 * Fixed the silc_client_close_connection to support closing
110 the client to client connections wihtout deleting too much
111 data. Affected file lib/silcclient/client.c.
113 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
114 are received if protocol used to be active but is not anymore
115 the application would crash due to NULL pointer dereference.
116 Affected files silcd/server.c and lib/silcclient/client.c.
118 * Added `hash' field to the SilcClientConnection to include
119 the hash function negotiated in the SKE protocol.
121 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
122 to set the channel founder authentication data. A client can
123 claim the founder rights later by providing the authentication
124 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
125 This way the channel founder can regain the channel founder
126 privileges even it is left the channel. This works only on
127 local server and the client must be connected to the same
128 server to be able to regain the founder rights. Updated the
129 protocol specs accordingly.
131 Added support to the CMODE command in the client to set the
132 founder auth data. Read the README to see how to set it.
134 Added support to the CUMODE command to claim the founder
135 rights. Read the README to see how to do it.
137 Added support for the founder authentication to the Channel
138 Entry in the server. Affected file silcd/idlist.h.
140 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
141 server's CMODE command. Affected file silcd/command.c.
143 * Added the following new functions into lib/silccore/silcauth.[ch]:
144 silc_auth_get_method and silc_auth_get_data.
146 * The server now saves the remote hosts public key to the
147 SilcIDListData pointer. Affected file silcd/protocol.c.
149 * The normal server now does not remove the channel entry from
150 the cache if the founder authentication data is set. It used
151 to remove it if the founder was the last one on the channel on
152 the server and left the channel. The auth data is saved and
153 if the channel is re-joined later the old entry is used with
154 the old auth data. Affected files silcd/command_reply.c and
157 * Removed the `pkcs' field from the SilcIDListData structure
158 in the server; it is not used. Affected file silcd/idlist.h.
160 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * Fixed packet processing on slow links. Partial packets were
163 never re-processed because the incoming data buffer was cleared
164 by the application. Application must not directly clear the
165 sock->inbuf, the packet processing routines handle it. Fixed
166 this in client library and in server.
168 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Fixed the WHOIS and IDENTIFY send reply function to really
171 check whether to send list or just one entry. Affected file
174 * Cleaned up the LEAVE command's channel key distribution. The
175 affected file silcd/command.c.
177 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
178 can enforce the channel mode as well. In that case the ID
179 includes the ID of the server. The code now enforces the
180 mode change if the router have different mode than the server.
182 * The notify client operation with CMODE_CHANGE notify can now
183 return NULL client_entry pointer if the CMODE was not changed
184 by client. Application must check for this.
186 * Added <Server ID> argument to INFO command to support server
187 info fetching by Server ID.
189 * Added silc_server_announce_get_channel_users to get assembled
190 packets of channel users of the specified channel. Affected
191 file silcd/server.[ch].
193 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
194 was freed underneath the ID Cache.
196 * Re-announce clients when the server received CHANNEL_CHANGE
197 notify from the router. Affected file silcd/packet_send.c.
199 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
202 crashed since it did not handle the fact that there is no cipher
203 called "3" and didn't check the error condition. Now fixed.
205 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
206 flag. It can be used to send message requests.
208 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Implemented the RESTART command in the client.
212 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
213 notice type messages. Added notice printing to the user
216 * The channel keys are not re-generated if the channel's mode
217 is PRIVKEY, ie private key on the channel exists. Affected
218 files silcd/server.c and silcd/command.c.
220 * Fixed a little bug in channel message delivery when channel
221 private keys are set in the server. Affected file is
224 * Changed the setting on channel->on_channel = TRUE from the
225 silc_client_save_channel_key to the JOIN command reply. The
226 key payload is not received if the private channel key is set.
227 Affected file lib/silcclient/command_reply.c and the
228 lib/silcclient/client_channel.c.
230 * When the CMODE_CHANGE notify is sent and the channel private
231 key mode is removed the channel key must be re-generated in
232 other cells as well. Added this support for the router in the
233 silcd/packet_receive.c.
235 * Added new local command NOTICE to send notice message on
236 channel. Affected file silc/local_command.[ch].
238 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
240 * Added new local command ME to the client. It is used to send
241 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
242 some action. Affected file silc/local_command.[ch].
244 * Changed channel_message and private_message client operations
245 to deliver the message flags to the application. Added also
246 the `flags' arguments to the silc_client_send_channel_message
247 and silc_client_send_private_message functions. Affected file
250 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Redefined the Private Message Payload to support private message
253 keys and to support the new private message flags. Updated
254 the protocol specs. Flags makes it possible to have for example
257 * Added new type SilcPrivateMessagePayload and defined an API
258 for it in the lib/silcclient/silcprivate.[ch].
260 * Tested private message private keys successfully. Tested the
261 private message key set, unset and list commands with the new
264 * Redefined the Channel Message Payload to include the channel
265 message flags (equal with private message flags) to support
266 for example CTCP style messages.
268 * Defined some of the message (for channel and private message)
269 flags. Updated the protocol specs and added the flags to the
270 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
272 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Added SilcKeyAgreementStatus type to the key agreement routines
275 to indicate the current status and error if one occured.
276 The status types are defined in the lib/silcclient/silcapi.h.
278 * Added new local command KEY that is used to set and unset private
279 keys for channels, set and unset private keys for private messages
280 with remote clients and to send key agreement requests and
281 negotiate the key agreement protocol with remote client. The
282 key agreement is supported only to negotiate private message keys,
283 it currently cannot be used to negotiate private keys for channels,
284 as it is not convenient for that purpose.
286 * Fixed a minor pending callback setting bug in the function
287 silc_client_get_client_by_id_resolve, now the function works.
288 Affected file lib/silcclient/idlist.c.
290 * Added function silc_net_get_local_port to get local bound
291 port by socket. Added to lib/silcutil/silcnet.[ch].
293 * Added `sockets' and `sockets_count' fields to the SilcClient
294 object. They hold the sockets of the listenning sockets in
295 the client. Listenning sockets may be for example the key
296 agreement server. Affected file lib/silcclient/client.[ch].
297 Added functions the silc_client_add_socket and the
298 silc_client_del_socket. They are exported to the application
301 * Added ~./silc/clientkeys to support other client's public keys.
303 * Renamed verify_server_key client operation to verify_public_key
304 and added one argument to indicate the type of the connection
305 (server, client etc.).
307 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Added silc_server_connection_auth_request to handle the
310 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
311 silcd/packet_receive.[ch].
313 * Added silc_server_send_connection_auth_request into the
314 silcd/packet_send.c to send the connection auth request packet.
316 * Cleaned up the silcd/protocol.c a bit and fixed some memory
319 * Fixed the public key authentication in responder side in the
320 server. The `auth_data' pointer includes the SilcPublicKey
321 not the path to the public key. Affected file silcd/protocol.c.
323 * Implemented the public key authentication in the initiator side
324 in the server. Affected file silcd/protocol.c.
326 * Removed the [RedirectClient] config section from the server
327 configuration. Is not needed and I don't want to implement it.
329 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Cleaned up the CMODE command in the server. It now works
332 correctly and supports all the modes defined in the protocol.
333 Affected file is silcd/command.c.
335 * Added `hmac_name' field to the SilcChannelEntry in the server
336 to hold the default HMAC of the channel. It can be set when
337 creating the channel (with JOIN command). Affected files
340 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
341 type to indicate the change of the current cipher and hmac
342 on the channel. Client can safely ignore the <cipher> argument
343 (if it chooses to do so) since the CHANNEL_KEY packet will
344 force the channel key change anyway. The <hmac> argument is
345 important since the client is responsible of setting the new
346 HMAC and the hmac key into use.
348 * Fixed the CMODE command in the client library as well.
350 * Tested CMODE command in router environment successfully.
352 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Show the version of the remote client (or server) when connecting
355 to the server. It is logged to the log file. Affected file
358 * Fixed the KILLED notify handling in the client library. The
359 client must be removed from all channels when receiving the
362 Also, do not remove the client entry when giving the KILL
363 command but when the KILLED notify is received.
365 * Removed silc_idlist_find_client_by_nickname from the server.
366 Not needed anymore. Affected files silcd/idlist.[ch].
368 * Implemented the CHANNEL_CHANGE notify type handling to the
369 server. Affected file silcd/server.c.
373 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added silc_server_send_notify_invite to send the INVITE
376 notify between routers.
378 * Implemented the INVITE command correctly to the server.
380 * Implemented the INVITE notify type handling in the server.
382 * Implemented the INVITE command to the client library and on the
385 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
387 * Added function silc_server_get_client_resolve to find the
388 client entry by ID from all ID lists and then resolve it
389 (using WHOIS) if it cannot be found. Affected file is
392 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Implemented the BAN command to the client library.
396 * The JOIN command in the server now checks the invite list
399 * Changed the silc_command_reply_payload_encode_va and the
400 silc_command_payload_encode_va to support that if argument is
401 NULL it ignores and checks the next argument. Affected file
402 lib/silccore/silccommand.c.
404 * Added silc_server_send_notify_ban to send the BAN notify
405 type between routers.
407 * Chaned the silc_notify_payload_encode to support that if
408 argument is NULL it ignores and checks the next argument.
409 Affected file lib/silccore/silcnotify.c.
411 * Tested ban lists in router environment successfully.
413 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Implemented BAN command to the server, in silcd/command.[ch].
417 * Removed the BAN and INVITE_LIST modes from the CMODE command
420 * Added function silc_string_match to regex match two strings.
421 Affected files lib/silcutil/silcutil.[ch].
423 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Redefined parts of the SilcChannelEntry in the server to support
426 the new ban and invite lists.
428 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Redefined the INVITE command. The same command can be used to
431 invite individuals to the channel but also to manage the invite
432 list of the channel (to add to and remove from the invite list).
433 Updated the protocol specs.
435 * Added new command SILC_COMMAND_BAN that can be used to manage
436 the ban list of the channel. Updated the protocol specs.
438 * Removed the channel modes: the SILC_CMODE_BAN and the
439 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
440 in the CMODE command. The equivalent features are now available
441 using INVITE and BAN commands. Updated the protocol specs.
443 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
444 in the network about change in the current ban list. The notify
445 type is not used by the client.
447 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
448 support the invite lists.
450 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Added new function silc_string_regexify that converts string
453 including wildcard characters into regex string that can
454 be used by the GNU regex library. Added into the file
455 lib/silcutil/silcutil.[ch].
457 Added silc_string_regex_combine to combine to regex strings
458 into one so that they can be used as one regex string by
459 the GNU regex library. Added into the file
460 lib/silcutil/silcutil.[ch].
462 Added silc_string_regex_match to match two strings. It returns
463 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
465 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * Imported GNU regex to the soruce tree into lib/contrib.
468 Fixed some compiler warning from the regex.c.

472 * Fixed MOTD command in the server to work in router environment.
474 * Fixed the MOTD command in the client library to support
475 the server argument in the command.
477 * Added `nickname_len' argument to the silc_idlist_add_client
478 in the server, as the `nickname' argument may be binary data
481 * Added silc_idlist_get_channels to return all channels from
484 * Implemented LIST command to the server. Affected file is
487 * Implemented the LIST command to the client library and on the
490 * Added [<user count>] argument to the LIST command reply.
491 With private channels the user count is not shown.
493 * Updated TODO and README.
495 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * The client entry's data.registered must be TRUE even with
498 global client entry on global client list. The data.registered
499 is used to check whether the client is anymore in the network,
500 for example with WHOWAS command so it must be valid.
502 * Fixed the WHOWAS command in the server. It now actually works
503 in router environment. Added function into silcd/command_reply.c
504 silc_server_command_reply_whowas_save.
506 * Added silc_idlist_purge function to the silcd/idlist.c
507 to periodically purge the ID Cache.

510 environment. Added <server name> argument to the INFO command
511 reply. Updated the protocol specs.
513 * Fixed minor bug in silc_idcache_purge to not purge if the
514 expire value is zero.
516 * Fixed various bugs in WHOIS and IDENTIFY command handling as
517 they were buggy because of the WHOWAS information.
519 * Fixed local command MSG to handle the async resolving of
520 the remote client properly. It used to fail the first MSG.
521 Affected file silc/local_command.c.
523 * Added `data_len' field to SilcIDCache context.
525 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
527 * Update TODO. Todo in commands in the server.
529 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
532 used by routers as broadcast packet to inform other routers
533 about the changed user mode.

536 silcd/packet_receive.c. Added the function
537 silc_server_send_notify_umode to the silcd/packet_send.[ch].
539 * Added new generic Channel Payload and deprecated the New Channel
540 Payload. The New Channel Payload is now the generic Channel
543 * Added new argument `mode' to the silc_server_send_new_channel
544 as it is required in the Channel Payload now.
546 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
547 and created a new and real SilChannelPayload to represent the
548 new generic Channel Payload. Implemented the encode/decode
549 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
551 * Added silc_server_get_client_channel_list to return the list
552 of channels the client has joined for WHOIS command reply.
553 Affected file silcd/server.[ch].
555 * Implemented the channel list sending in the WHOIS command reply
556 in server and in the client.
558 Implemented the channel list displaying on the user interface
559 as well. Affected file silc/client_ops.c.
561 * Added silc_channel_payload_parse_list to parse list of Channel
562 Payloads. It returns SilcDList list of SilcChannelPayloads.
563 Client for example can use this function to parse the list of
564 channels it receives in the WHOIS command reply. The caller
565 must free the list by calling silc_channel_payload_list_free.
566 Affected files lib/silccore/silcchannel.[ch].
568 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Added one new argument <user mode> to the WHOIS command reply
571 to return the mode of the user in SILC. Updated the protocol

578 * Fixed the mode printing on the user interface on joining.
579 Affected file silc/client_ops.c.
581 * Implemented the UMODE command and user modes in general to the
582 client library and to the user interface.
584 * Implemented the UMODE command to the server.
586 * The server now sends UNKNOWN_COMMAND error status if client sends
587 unknown command. Affected file silcd/command.c.
589 * All server commands now handle the command identifier the right
590 way when sending the command reply to the client. The client can
591 use to identify the command replies with the identifier.
593 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Added silc_server_get_client_route to resolve the route to
596 the client indicated by the client ID. Affected file is
599 * Added silc_server_relay_packet as general function to relay
600 packet to arbitrary destination. This deprecates functions
601 like _send_private_message_key, _relay_notify etc. Affected
602 file is silcd/packet_send.[ch].
604 Removed silc_server_send_key_agreement,
605 silc_server_send_private_message_key and
606 silc_server_packet_relay_notify functions from the file
607 silcd/packet_send.[ch].
611 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
612 server. Affected file silcd/packet_receive.[ch].
614 * Implemented the KILL command to the client. Implemented the
615 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
616 Affected files lib/silcclient/command[_reply].c and
617 lib/silcclient/client_notify.c. Implemented the KILL notify
618 printing in the user inteface.
620 * Fixed a lot silc_parse_nick memory leaks from the client
621 library in the file lib/silcclient/command.c.
623 * Changed the silc_server_send_notify_on_channels's `sender'
624 argument from SilcSocketConnection to SilcClientEntry to
625 check the sender as entry and not as connection object and not
626 to send to the client provided as argument. The affected file
627 is silcd/packet_send.[ch].
629 * The notify packets that are destined directly to the client used
630 to not to be processed by the server. Now changed that and the
631 server processes all notify packets. After relaying the packet
632 to the client the notify packet is processed in the server.
634 * The silc_server_free_client_data now checks whether there is
635 pending outgoing traffic for the client and purges the data to
636 the network before removing the client entry.
638 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
641 an client is killed from the SILC Network. Updated the protocol
644 Added new function silc_server_send_notify_killed to the
645 silcd/packet_send.[ch].
647 * Added function silc_server_packet_relay_notify to relay notify
648 packets that are destined directly to a client. In this case
649 the server does not process the notify packets but merely relays
650 it to the client. Affected file silcd/packet_send.[ch].
652 Added also silc_server_packet_process_relay_notify to check
653 whereto relay the notify. Affected file is
654 silcd/packet_receive.[ch].
656 * Implemented the KILL command to the server.
660 * Added the backup schema desgined last fall to the protocol
661 specs for everyone to see. The specification is in the
662 *-spec-xx.txt draft and the packet type definitions for the
663 backup routers is in *-pp-xx.txt draft. Thusly, added also
664 new packet type SILC_PACKET_CELL_ROUTERS.
666 * A big security problem in the implementation discovered. The
667 signoff of an client did not cause new channel key generation
668 which it of course should've done. The channel keys must be
669 always re-generated when client leaves (or signoffs) the channel.
670 The silc_server_remove_from_channels funtion now handles
671 the channel key re-generation.
673 * Added `sender' argument to the silc_server_send_notify_on_channels
674 to not to send the client provided as argument. Affected file
675 silcd/packet_send.[ch].
677 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Implemented OPER and SILCOPER commands into the server and
682 * Added silc_auth_verify and silc_auth_verify_data to verify
683 the authentication directly from the authentication payload.
684 It supports verifying both passphrase and public key based
685 authentication. Affected file lib/silccore/silcauth.[ch].
687 * Added `hash' field to the SilcIDListData structure. It is the
688 hash negotiated in the SKE protocol. Affected file is
691 * Slight redesigning of the SilcAuthPayload handling routines.
692 Do not send SilcPKCS but SilcPublicKey as argument.
694 * Implemented the public key authentication support to the
695 serverconfig. The public key is loaded from the provided path
696 and saved as authentication data to void * pointer. Thus,
697 changed the unsigned char *auth_data to void *auth_data;
699 * Fixed SHUTDOWN command to send the reply before the server
700 is shutdown. :) Affected file silcd/command.c.
702 * Fixed fatal bug in CONNECT command. The hostname was invalid
703 memory and server crashed. Affected file silcd/command.c.
705 * Fixed fatal bug in CLOSE command. The server_entry became
706 invalid but was referenced later in the command. Affected file
709 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
711 * Fixed fatal bug in failure packet handling. Server ignored
712 the failure and thus crashed when it came.
716 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
718 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
719 that the command may be executed only once in (about) 2 seconds.
720 The old SILC_CF_LAG flag is same but allows command bursts up
721 to five before limiting.
723 Added the support for CF_LAG and CF_LAG_STRICT flags to the
724 server code. Various commands now includes the CF_LAG_STRICT
725 flag to disallow any kind of miss-use of the command.
727 * Fixed the silc_buffer_unformat to not to allocate any data
728 if the length of the data is zero. It used to allocate the
729 length + 1. Affected file lib/silcutil/silcbuffmt.c.
731 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Changed the format of AdminConnection configuration section
734 in the server. Added username of the admin to the format.
735 Affected files silcd/serverconfig.[ch].
737 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
738 to return admin configuration data by host, username and/or
741 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Implemented WHOWAS command to the server. Added the functions:
745 silc_server_command_whowas_parse,
746 silc_server_command_whowas_send_reply,
747 silc_server_command_whowas_from_client and
748 silc_server_command_whowas_from_server
750 * Added <Client ID> argument to the WHOWAS command reply. Updated
751 the protocol specs accordingly.
753 * Implemented WHOWAS command and command_reply to the client
756 Implemented the WHOWAS printing on the user interface.
758 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Added new argument to the WHOWAS command reply, the real name.
761 It is an optional argument. Updated the protocol specs.
763 * Added SilcIDCacheDestructor callback that is registered when
764 the SilcIDCache is allocated. The callback is called when
765 an cache entry in the ID Cache expires, or is purged from the
766 cache. Added into lib/silccore/idcache.[ch].
768 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
769 to destruct the client entries when the cache entry expires.
770 Other ID Cache's in server and in the client library ignores
773 * If the ID Cache entry's `expire' field is zero then the entry
774 never expires. Added boolean `expire' argument to the
775 silc_idcache_add function in the lib/silccore/idcache.[ch].
776 If it is TRUE the default expiry value is used.
778 * Added silc_server_free_client_data_timeout that is registered
779 when client disconnects. By default for 5 minutes we preserve
780 the client entry for history - for WHOWAS command.
782 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added support to the server to enforce that commands are not
785 executed more than once in 2 seconds. If server receives
786 commands from client more frequently, timeout is registered
787 to process the commands. Affected file silcd/command.c.
788 Added new function silc_server_command_process_timeout.
790 * Changed NICK_NOTIFY handling in client library to check that
791 if the client's nickname was changed, so there is no need to
792 resolve anything from the server.
794 * Removed error printing from the WHOIS and IDENTIFY commands.
795 If error occurs then it is ignored silently in the client library.
796 The application, however, may map the received error to
797 human readable error string. The application currently maps
798 the NO_SUCH_NICKNAME error to string.
800 * Made the command status message public to the application. Moved
801 them from lib/silcclient/command_reply.c to
802 lib/silcclient/command_reply.h. The application can map the
803 received command status to the string with the
804 silc_client_command_status_message function.
806 * Added check to the server to check that client's ID is same
807 as the Source ID in the packet the client sent. They must
810 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Added dist-bzip hook to the Makefile.am to make bzip2
813 compressed distributions.
815 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Server now enforces the maximum length for the nickname and
818 the channel as protocol specification dictates. 128 bytes for
819 nickname and 256 bytes for channel name.
821 * Moved the WHOIS printing to the application. The client libary
822 does not print out the WHOIS information anymore, the application
823 must do it. Renamed silc_client_command_reply_whois_print to
824 the silc_client_command_reply_whois_save.
826 The client's idle time is also sent to the application now, and
827 the idle is shown on screen.
829 * Added silc_client_command_reply_identify_save to save the
830 received IDENTIFY entries.
832 * Do not check for channel private keys in message sending and
833 reception if the channel does not have the PRIVKEY mode set.
834 Affected file lib/silclient/client_channel.c.
836 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
839 just surfaced after chaning the JOIN procedure.
841 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Added silc_client_get_clients_by_list to get client entries
844 from Client ID list, that is returned for example by JOIN
845 and USERS command replies. The application should use this
846 function for example when JOIN command reply is received to
847 resolve the clients already on the channel (library does not
848 do that anymore as USERS command reply is not used in the JOIN
849 procedure anymore). Affected files lib/silcclient/silcapi.h and
850 lib/silcclient/idlist.c.
852 * JOIN command reply and USERS command reply returns now SilcBuffer
853 pointers instead of unsigned char pointers when returning
854 the client list and mode list.
856 * Added <Client ID> argument to the JOIN command reply, mainly
857 for the server to identify for which client the command was
858 originally sent. Updated protocol specs accordingly.
860 * Added SilcDlist private_key pointer to the SilcChannelEntry
861 in the client to support the channel private keys. Affected
862 file is lib/silcclient/idlist.h.
864 * Added SilcChannelPrivateKey argument to the function
865 silc_client_send_channel_message so that application can choose
866 to use specific private ke if it wants to. If it is not provided,
867 the normal channel key is used, unless private keys are set.
868 In this case the first (key that was added first) is used
869 as the encryption key.
871 * Implemented the support for channel private key handling.
872 Implemented the following functions:
874 silc_client_add_channel_private_key,
875 silc_client_del_channel_private_keys,
876 silc_client_del_channel_private_key,
877 silc_client_list_channel_private_keys and
878 silc_client_free_channel_private_keys
880 Affected file lib/silcclient/client_channel.c.
882 * Added the support for the private keys in the channel message
883 sending and encryption and in the message reception and
884 decryption. Affected funtions are
885 silc_client_send_channel_message and silc_client_channel_message.
887 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Added SKE's key verify callback to the client library's
890 KE protocol context. Affected files lib/silcclient/protocol.[ch].
892 * Removed the statement that server (or router) must send USERS
893 command reply when joining to the channel so that the client
894 knows who are on the channel. Instead, the client list and
895 client's mode list is now sent in the JOIN command reply to the
896 client who joined channel. This is better solution.
898 * Added function silc_server_get_users_on_channel and function
899 silc_server_save_users_on_channel to the silcd/server.[ch].
901 * Removed function silc_server_command_send_users from the
904 * Do not show topic on the client library anymore. The topic is
905 sent in the command reply notify to the application and the
906 application must show the topic now.
908 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Added client searching by nickname hash into the IDENTIFY and
911 WHOIS commands in the server as they were clearly missing from
912 them. Affected file is silcd/command.c.
914 * Fixed a bug in private message receiving in the client library.
915 The remote ID was freed and it wasn't supposed, now it is
918 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Minor fix to the channel payload; allocate the data area, as it
921 needs to be of specific length.
923 * If the key agreement port is zero then the operating
924 system will define the bound port. Affected files are
925 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
927 * Added new function silc_channel_payload_decrypt into the file
928 lib/silccore/silcchannel.[ch].
930 * Moved the channel message etc, check from silc_packet_decrypt
931 to applications. The library calls now a generic
932 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
933 when the packet is either normal or special. This was done to
934 allow more wide range of checking that was not allowed when
935 the code was in library. Now applications can do virtually any
936 checks to the packet and return to the library the decision how
937 the packet should be processed. Affected files are
938 lib/silccore/silcpacket.[ch].
940 Added silc_server_packet_decrypt_check to the server and
941 silc_client_packet_decrypt_check to the client library.
943 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
944 to send with specified source and destination information.
946 * Channel message delivery between routers was broken after the
947 channel key distribution was fixed earlier. The channel key
948 was used be to distributed to other routers as well which is not
949 allowed by the protocol. Now this is fixed and channel keys
950 really are cell specific and the channel message delivery between
951 routers comply with the protocol specification.
953 * Fixed various commands in server to check also the global list
954 for the channel entry and not just the local list. The affected
955 file silcd/command.c.
957 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Added assert()s to buffer formatting and unformatting routines
960 to assert (if --enable-debug) when error occurs. Affected
961 file: lib/silcutil/silcbuffmt.c.
963 * Changed to auto-reconnect to check whether the remote host is
964 router and register the re-connect timeout if it is. It used
965 to check that whether we are normal server, but router must do
966 auto-reconnect with another router as well. Affected file
969 * Removed the [<key len>] option from CMODE command as the cipher
970 name decides the key length, nowadays. See the defined ciphers
971 from the protocol specification.
973 * Added [<hmac>] option to the CMODE command to define the HMAC
974 for the channel. Added SILC_CMODE_HMAC channel mode.
976 * Added [<hmac>] option for the JOIN command so that user can
977 select which HMAC is used to compute the MACs of the channel
980 * Added Hmac field to the Channel Message Payload. The integrity
981 of plaintext channel messages are now protected by computing
982 MAC of the message and attaching the MAC to the payload. The
983 MAC is encrypted. Now, it is clear that this causes some
984 overhead to the size of the packet but rationale for this is that
985 now the receiver can verify whether the channel message decrypted
986 correctly and also when private keys are set for the channel the
987 receiver can decrypt the packet with several keys and check from
988 the MAC which key decrypted the message correctly.
990 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
991 lib/silccrypt/silccipher.[ch].
993 * Added silc_hash_len to return the digest length into the
994 lib/silcrypt/silchash.[ch].
996 * Rewrote parts of Silc Channel Payload interface in the
997 lib/silccore/silcchannel.[ch]. The encode function now also
998 encrypts the packet and parse function decrypts it.
1000 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Fixed a minor formatting bug in the SKE's key material processing.
1003 It actually might have processed the keys wrong way resulting
1006 * Redefined the mandatory HMAC algorithms and added new algorithms.
1007 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1008 and hmac-md5 truncated to 96 bits. The mandatory is now
1009 hmac-sha1-96. Rest are optional (including the one that used
1010 to be mandatory). Rationale for this is that the truncated HMAC
1011 length is sufficient from security point of view and can actually
1012 make the attack against the HMAC harder. Also, the truncated
1013 HMAC causes less overhead to the packets. See the RFC2104 for
1016 * Added new [hmac] configuration section. The SKE used to use
1017 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1018 is of course wrong. The official names that must be proposed in
1019 the SKE are the ones defined in the protocol specification
1020 (hmac-sha1-96 for example). The user can configure any hmac
1021 using any hash function configured in the [hash] section. At
1022 least, the mandatory must be configured.
1024 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1026 * Added HMAC list to the SKE proposal list. It has now both
1027 hash algorithm list and HMAC list. This makes the protocol
1028 incompatible with previous versions. The SKE now seems to work
1029 the way it is supposed to work, for the first time actually.
1031 * Defined plain Hash algorithms to the protocol specification.
1034 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Implemented support for key agreement packets into the server.
1037 Added functions silc_server_key_agreement and
1038 silc_server_send_key_agreement. Other than these functions,
1039 server has nothing to do with this packet.
1041 * Added support for private message key packets into the server.
1042 Added functions silc_server_private_message_key and
1043 silc_server_send_private_message_key.
1047 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1048 called in the protocol's final callback instead in the END
1049 protocol state. This makes a little more sense and in the same
1050 time in client we can use the same protocol routines for normal
1051 key exchange and to key agreement packet handling as well.
1053 * Added to both client's and server's KE protocol context the
1054 SilcSKEKeyMaterial pointer to save the key material. We will
1055 bring the key material to the protocol's final callback by doing
1056 this. The final callback must free the key material.
1058 * Added SKE's packet_send callback into client's KE protocol
1059 context so that the caller can choose what packet sending function
1060 is used. This way we can use different packet sending when
1061 doing normal SKE when doing key agreement packet handling (in
1062 the key agreement packet handling we do not want to encrypt
1065 * Implemented the responder side of the key agreement routines
1066 in the client. The client can now bind to specified port and
1067 accept incoming key negotiation. The key material is passed
1068 to the application after the protocol is over.
1070 * Implemented the processing of incoming Key Agreement packet
1071 in the client. Added function silc_client_key_agreement to
1074 * Implemented the intiator side of the key agreement routines
1075 in the client. The client can now initiate key agreement with
1076 another remote client. The key material is passed to the
1077 application after the protocol is over.
1079 * Created client_keyagr.c to include all the key agreement
1082 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1083 SILC_TASK_CALLBACK except that it is not static.
1085 * Created client_notify.c and moved the Notify packet handling
1086 from the client.[ch] into that file.
1088 * Created client_prvmsg.c and moved all private message and
1089 private message key routines from the client.[ch] into that file.
1091 * Create client_channel.c and moved all channel message and
1092 channel private key routines from the client.[ch] into that file.
1094 * Changed silc_client_get_client_by_id_resolve to resolve with
1095 WHOIS command instead of IDENTIFY command, in the file
1096 lib/silclient/idlist.c.
1098 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Implemented the SKE's responder side to the Client library.
1102 * When FAILURE is received to the protocol do not trust it
1103 blindly. Register a timeout to wait whether the remote closes
1104 the connection as it should do it, only after that process the
1105 actual failure. This was changed to both client and server.
1107 * Added client_internal.h to include some of the structures
1108 there instead of client.h in lib/silcclient/.
1110 * Added function silc_task_unregister_by_callback to unregister
1111 timeouts by the callback function.
1113 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Some "Incomplete WHOIS info" errors has been appearing on the
1116 log files. Took away the entry->userinfo check from WHOIS
1117 reply sending. The entry->userinfo is now " " if client did not
1118 provide one. I thought this was fixed earlier but something
1119 is wrong still. Let's see if the error still appears.
1121 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Fixed a minor bug in the login when the channel key is
1124 re-generated in the server. It used to generate the key in
1125 wrong order and thus caused problems in the channel traffic.
1127 * Fixed a minor bug in channel key distsribution after
1128 KICK command. The key was not sent to the router even though
1131 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Added silc_ske_process_key_material_data as generic routine
1134 to process any key material as the SILC protocol dictates. The
1135 function is used by the actual SKE library but can be used by
1136 applications as well. This relates to the private message keys
1137 and the channel private keys since they must be processed the
1138 same way the normal SILC session keys. The protocol dictates
1139 this. Affected files: lib/silcske/silcske.[ch].
1141 Added also silc_ske_free_key_material to free the
1142 SilcSKEKeyMaterial structure.
1144 * Defined silc_cipher_set_key function to set the key for
1145 cipher without using the object's method function. The affected
1146 files: lib/silccrypt/silccipher.[ch].
1148 * Implemented silc silc_client_add_private_message_key,
1149 silc_client_add_private_message_key_ske,
1150 silc_client_del_private_message_key,
1151 silc_client_list_private_message_keys and
1152 silc_client_free_private_message_keys functions in the
1155 Added functions silc_client_send_private_message_key to send
1156 the Private Message Key payload and silc_client_private_message_key
1157 to handle incoming Private Message Key payload.
1159 * Added Cipher field to the Private Message Key payload to set
1160 the cipher to be used. If ignored, the default cipher defined
1161 in the SILC protocol (aes-256-cbc) is used.
1163 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Removed lib/silcclient/ops.h file.
1167 Redefined parts of the SILC Client Library API. Created new
1168 file silcapi.h that deprecates the ops.h file and defines the
1169 published Client Library API. Defined also private message key
1170 API and channel private key API into the file.
1172 This is the file that the application must include from the
1173 SILC Client Library. Other files need not be included by
1174 the application anymore.
1176 * Added new key_agreement client operation callback and also
1177 defined the Key Agreement library API for the application.
1179 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1182 is used by clients to request key negotiation between another
1183 client in the SILC network. If the negotiation is started it
1184 is performed using the SKE protocol. The result of the
1185 negotiation, the secret key material, can be used for example
1186 as private message key.
1188 Implemented the Key Agreement payload into the files
1189 lib/silccore/silauth.[ch].
1191 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Redefined ciphers for the SILC protocol. Added some new ciphers
1194 and defined the key lengths for the algorithms. Changed the
1195 code accordingly. The default key length is now 256 bits.
1197 * Fixed SKE key distribution function silc_ske_process_key_material
1198 when the key length is more than 128 bits. The default key
1199 length in SILC is now 256 bits.
1201 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1202 to indicate unsupported algorithm.
1204 * Renamed rijndael.c to aes.c and all functions as well.
1206 * Fixed a long standing channel key setting bug in client library.
1207 Weird that it has never surfaced before.
1209 * Fixed bug in channel deletion. If the entire channel is removed
1210 then it must also delete the references of the channel entry
1211 from the client's channel list as the client's channel entry and
1212 the channel's client entry share same memory.
1214 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Implemented CONNECT and SHUTDOWN commands in the client.
1218 * Implemented CLOSE command to the client.
1220 * Added the function silc_idlist_find_server_by_name into the
1221 files silcd/idlist.[ch].
1223 Added the function silc_idlist_find_server_by_conn into the
1224 files silcd/idlist.[ch].
1226 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * DIE command was renamed to SHUTDOWN. Updated the both code
1231 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1232 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1234 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1237 * Added function silc_server_create_connection function to create
1238 connection to remote router. My server implementation actually
1239 does not allow router to connect to normal server (it expects
1240 that normal server always initiates the connection to the router)
1241 so the CONNECT command is only good for connecting to another
1244 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1247 or some other client was kicked from the channel.
1249 Implemented the handling of the notify type to both client
1252 Implemented silc_server_send_notify_kicked to send the KICKED
1253 notify. It is used to send it to the server's primary router.
1255 * Implemented the KICK command into server and client.
1257 * Added `query' argument to the silc_idlist_get_client function
1258 to indicate whether to query the client from server or not if
1261 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1262 to indicate that the client is not channel founder.
1266 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Removed the rng context from SilcPacketContext structure and
1269 changed that the packet routine uses the Global RNG API.
1271 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Added support for quit message that client can "leave" on the
1274 channel when it quits the SILC. It is ditributed inside the
1275 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1277 Added silc_server_free_client_data that will take the
1278 signoff message as argument.
1280 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1282 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Updated parts of the protocol specification to keep it up
1287 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1290 payloads in one packet.
1292 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1293 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1294 use now the new List flag.
1296 * Also deprecated the following packet types: REPLACE_ID,
1297 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1299 * Added list support for Notify packet in server.
1301 * Added silc_server_send_notify_channel_change to send the
1302 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1303 the silc_server_send_replace_id.
1305 * Added silc_server_send_notify_nick_change to send the
1306 NICK_CHANGE notify type. Deprecates the function
1307 silc_server_send_replace_id.
1309 * Added silc_server_send_notify_join to send the JOIN notify type.
1310 Deprecates the function silc_server_send_new_channel_user.
1312 * Added silc_server_send_notify_leave to send LEAVE notify type.
1313 Deprecates the function silc_server_send_remove_channel_user.
1315 * Added silc_server_send_notify_cmode and
1316 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1317 types. Deprecates the silc_server_send_set_mode function.
1319 * Added SERVER_SIGNOFF notify type to indicate that server has
1320 quit. This means that all clients on the channel from that
1321 server will drop. This can be also used when netsplit happens.
1323 Deprecated REMOVE_ID packet type since it is not needed anymore
1326 Added silc_server_send_notify_server_signoff to send the
1327 SERVER_SIGNOFF notify type. Deprecates the function
1328 silc_server_send_remove_id.
1330 Added also silc_server_send_notify_signoff to send the
1331 SIGNOFF notify type.
1333 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1334 SILC protocol from this day on. Changed the protocol
1335 specification as well.
1337 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1338 notify type. It is used between routers to notify about
1339 topic changes on a channel.
1341 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1344 * Partly updated the protocol specification to comply with the
1345 changes now made. It is still though a bit outdated.
1347 * The JOIN notify type now takes one extra argument <Channel ID>.
1348 The packet used to be destined to the channel but now the
1349 JOIN type may be sent as list thus it is impossible to
1350 destine it to any specific channel. By adding this argument
1351 it is again possible.
1353 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Added CREDITS file. The CHANGES and CREDITS file will appear
1356 in the distribution as well.
1358 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1361 types in the server's silcd/packet_receive.c.
1363 * Implemented CMODE and CUMODE to work in router environment.
1365 * Fixed minor encoding and decoding buglet from the
1366 lib/silccore/silcmode.c.
1368 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1371 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1373 * Changed all SilcConfigServer* and silc_config_server* to
1374 SilcServerConfig* and silc_server_config*, respectively.
1377 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1379 * Associated the ID (client or server ID) to the Authentication
1380 Payload to avoid any possibility of forging. Updated the
1381 protocol specification and the code accordingly.
1383 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * The RSA key length is now save to the RsaKey context in the
1386 key generation process in lib/silccrypt/rsa.c. The key length
1387 is now used to figure out the maximum size of the block allowed
1388 to be encrypted/signed.
1390 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1391 is equivalent to the silc_mp_mp2bin but does not allocate any
1394 * Changed silc_mp_mp2bin API to take length argument. If it is
1395 non-zero then the buffer is allocated that large. If zero, then
1396 the size is approximated using silc_mp_sizeinbase, which however
1399 * Created Global RNG API which is global RNG that application can
1400 initialize. After initializing, any routine anywhere in the
1401 code (including library) can use RNG without allocating a new
1402 RNG object. This was done to allow this sort of use of the
1403 RNG in code that has no chance to allocate RNG object. All
1404 applications currently allocate this and many routines in the
1405 library use this. Affected file lib/silccrypt/silcrng.[ch].
1407 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1408 it to use the Global RNG API.
1410 * Defined Authentication Payload into protocol specification that
1411 is used during SILC session to authenticate entities. It is
1412 used for example by client to authenticate itself to the server
1413 to obtain server operator privileges.
1415 Implemented this payload into the lib/silccore/silcauth.[ch].
1416 Implemented also routines for public key based authentication
1417 as the new protocol specification dictates.
1419 Moved definitions of different authentication methods from
1420 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1422 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1423 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1424 silc_pkcs_verify_with_hash functions into the file
1425 lib/silccrypt/silcpkcs.[ch].
1427 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * The client entry's userinfo pointer must be always valid.
1430 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1431 will fail since it requires the userinfo. Now, the userinfo
1432 is allocated as "" if actual userinfo does not exist. Actually,
1433 it must exist and it is totally Ok to drop client connections
1434 that does not announce the userinfo. However, we will make
1435 this workaround for now.
1437 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1438 to return the remote port by socket.
1440 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1443 SILC_SERVER_PENDING_EXEC and added an new macro
1444 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1445 data or when error occurs while processing the pending command.
1447 Added new argument `destructor' into silc_server_command_pending
1448 and to the SilcServerCommandPending object. This destructor is
1449 now called after calling the pending callback or if error occurs
1450 immediately. If error occurs the actual pending callback won't
1451 be called at all - only the destructor. The destructor may be
1452 NULL if destructor is not needed.
1454 All this applies for client library code as well. Similar
1455 changes were made there as well for the pending commands.
1457 In the client, the application must now allocate the
1458 SilcClientCommandContext with the silc_client_command_alloc
1461 * Added reference counter to the SilcServerCommandContext. Added
1462 function silc_server_command_alloc and silc_server_command_dup
1465 Same type of functions added to the client library for the same
1468 * Removed the cmd_ident from IDListData away since it is now
1469 global for all connections. It is the command identifier used
1470 in command sending and with pending commands. The affected file
1473 * Added reference counter to the SilcSocketConnection objecet to
1474 indicate the usage count of the object. The object won't be
1475 freed untill the reference counter hits zero. Currently only
1476 server uses this, and client ignores it. The client must be
1477 set to use this too later. The affected files are
1478 lib/silccore/silcsockconn.[ch]. Added also the function
1479 silc_socket_dup to increase the reference counter.
1481 This was mainly added because it is possible that the socket
1482 is removed underneath of pending command or other async
1483 operation. Now it won't be free'd and proper DISCONNECTING
1484 flags, etc. can be set to avoid sending data to connection that
1485 is not valid anymore.
1487 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1488 the connection. After that it sets SILC_SET_DISCONNECTED.
1489 It is, however, possible that the socket data is not still freed.
1490 The silc_server_packet_process now checks that data is not
1491 read or written to connection that is DISCONNECTED. The socket
1492 get's freed when the reference counter hits zero.
1494 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Changed the client operation API: channel_message operation's
1497 `sender' is now the client entry of the sender, not the nickname
1498 and the `channel' is the channel entry, not the channel name.
1500 In the private_message operation the `sender' is now also the
1501 client entry of the sender not the nickname.
1503 Affected file is lib/silcclient/ops.h and all applications
1504 using the client operations.
1506 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Moved the calling of ops->connect() from connect_to_server_final
1509 into receive_new_id functin since that is the point when the
1510 client is actually allowed to send traffic to network. The
1511 affected file is lib/silcclient/client.c.
1513 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1516 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1517 (if needs broadcasting) instead of broadcasting the packets one
1518 by one which would make a burst in the network traffic.
1520 * Added `broadcast' argument to the functions in silcd/server.[ch]
1521 silc_server_create_new_channel[_with_id] to indicate whether
1522 to send New Channel packet to primary router.
1524 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Added new function into the silcd/server.[ch] files:
1527 silc_server_create_new_channel_with_id to create new channel with
1528 already existing Channel ID.
1530 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1531 lib/silccore/silcpacket.h. This packet is used t send list of
1532 Set Mode payloads inside one packet. Server uses this to set
1533 the modes for the channels and clients on those channels, that it
1534 announced to the router when it connected to it. The protocol
1535 specification has been updated accordingly.
1537 * The silc_server_new_channel did not handle the packet coming
1538 from normal server as it normally does not send that. However,
1539 when it announces its channels it does send it. Implemented
1540 the support for that.
1542 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1543 into the file lib/silccore/id.h.
1545 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Fixed memory leaks in the functions silc_idlist_del_client,
1548 silc_idlist_del_channel and silc_idlist_del_server in the file
1549 silcd/idlist.c. All of those leaked like a sieve.
1551 * Fixed some small memory leaks in the client's function
1552 silc_client_notify_by_server.
1554 * Added functions into silcd/server.c: silc_server_announce_clients,
1555 silc_server_announce_channels and silc_server_announce_server.
1556 These functions are used by normal and router server to announce
1557 to its primary router about clients, channels and servers (when
1558 router) that we own. This is done after we've connected to the
1561 These functions effectively implements the following packet types:
1562 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1563 and SILC_PACKET_NEW_ID_LIST.
1565 * Added new functions into the silcd/packet_receive.[ch]:
1566 silc_server_new_id_list, silc_server_new_channel_list and
1567 silc_server_new_channel_user_list to handle the incoming
1568 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1570 * Added support of changing Channel ID in the function
1571 silc_server_replace_id. If the server that announces a channel
1572 to the router already exists in the router (with same name but
1573 with different Channel ID), router is responsible to send
1574 Replace ID packet to the server and force the server to change
1575 the Channel ID to the one router has.
1577 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1578 client that the Channel ID has been changed by the router. The
1579 normal server sends this to the client. Client must start using
1580 the new Channel ID as the channel's ID.
1582 Implemented handling of this new type into lib/silcclient/client.c
1583 into the function silc_client_notify_by_server.
1585 * Added new function silc_idlist_replace_channel_id into the files
1586 silcd/idlist.[ch] to replace the Channel ID.
1588 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Call silc_server_command_identify_check always when processing
1591 the IDENTIFY command in silcd/command.c
1593 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1596 send keepalive packets. The packet can be sent by clients,
1597 servers and routers.
1599 Added function silc_socket_set_heartbeat into the file
1600 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1601 If not set, the heartbeat is not performed. The actual
1602 heartbeat is implemented in the low level socket connection
1603 library. However, application is responsible of actually
1606 Added silc_server_send_heartbeat to send the actual heartbeat
1607 packet into silcd/packet_send.[ch]. Server now performs
1608 keepalive with all connections.
1610 * Added silc_task_get_first function into lib/silcutil/silctask.c
1611 to return the timeout task with shortest timeout. There was a bug
1612 in task unregistration that caused problems. TODO has been
1613 updated to include that task system must be rewritten.
1615 * The client library will now resolve the client information when
1616 receiving JOIN notify from server for client that we know but
1617 have incomplete information.
1619 * Rewrote parts of silc_server_remove_from_channels and
1620 silc_server_remove_from_one_channel as they did not remove the
1621 channel in some circumstances even though they should've.
1623 * Encryption problem encountered in server:
1625 The LEAVE command used to send the Channel Key packet to the
1626 router immediately after generating it. However, the code
1627 had earlier sent Remove Channel user packet but not immediately,
1628 ie. it was put to queue. The order of packets in the router
1629 was that Channel Key packet was first and Remove Channel User
1630 packet was second, even though they were encrypted in the
1631 reverse order. For this reason, MAC check failed. Now, this
1632 is fixed by not sending the Channel Key packet immediately but
1633 putting it to queue. However, this is more fundamental problem:
1634 packets that are in queue should actually not be encrypted
1635 because packets that are sent immediately gets encrypted
1636 actually with wrong IV (and thus MAC check fails). So, packets
1637 that are in queue should be encrypted when they are sent to
1638 the wire and not when they put to the queue.
1640 However, the problem is that the current system has not been
1641 designed to work that way. Instead, the packet is encrypted
1642 as soon as possible and left to the queue. The queue is then
1643 just purged into wire. There won't be any fixes for this
1644 any time soon. So, the current semantic for packet sending
1647 o If you send packet to remote host and do not force the send
1648 (the packet will be in queue) then all subsequent packets to the
1649 same remote host must also be put to the queue. Only after the
1650 queue has been purged is it safe again to force the packet
1653 o If you send all packets immediately then it safe to send
1654 any of subsequent packets through the queue, however, after
1655 the first packet is put to queue then any subsequent packets
1656 must also be put to the queue.
1658 Follow these rules and everything works fine.
1660 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Added new function silc_server_remove_clients_by_server to
1663 remove all client entries from ID list when the server connection
1664 is lost. In this case it is also important to invalidate all
1665 client entires as they hold the invalid server entry. This
1666 fixes fatal bug when server has lost connection and will reconnect
1669 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Made some sanity checks to silc_server_daemonise like to check
1672 whether the requested user and group actually exists.
1674 * Added sanity check to SKE's silc_ske_responder_finish to check
1675 that the public and private key actually is valid.
1677 * Invalidate the client's nickname when receiving Replace ID
1678 packet and the Client ID is being replaced. This means that the
1679 server will query the nickname if someone needs it (client)
1682 * Sort the ID Cache in client library when the ID Cache data
1683 has changed (needs sorting).
1685 * Do not allow for SILC client to create several connections to
1686 several servers. The client does not support windows right now
1687 and generating multiple connections causes weird behaviour.
1689 Irssi-silc client does support windows and can handle several
1690 connections without problems, see: www.irssi.org and SILC plugin.
1692 * Fixed some places where client was added to the IDList. The
1693 rule of thumb is following (in order to get everything right):
1694 If the client is directly connected local client then the
1695 `connection' argument must be set and `router' argument must be
1696 NULL to silc_idlist_add_client function. If the client is not
1697 directly connected client then the `router' argument must
1698 bet set and the `connection' argument must be NULL to the
1699 silc_idlist_add_client function.
1701 * The funtion silc_server_packet_send_local_channel actually did
1702 not check whether the client was locally connected or not. It
1703 does that now. Fixed a bug related to LEAVE command.
1705 * Fixed Remove Channel User payload parsing bug in server's
1706 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1708 * The server's silc_server_save_channel_key now checks also the
1709 global ID list for the channel as it might not be in the local
1710 list. Fixed a bug related to LEAVE command.
1712 * Is this the end of the [<unknown>] buglet that has been lurking
1713 around for a long time? A little for loop fix in server's
1714 silc_server_command_whois_parse that is used by both IDENTIFY
1715 and WHOIS command. At least, this was a clear bug and a cause
1716 of one type of [<unknown>] buglet.
1718 * WHOIS and IDENTIFY commands call the function
1719 silc_server_command_[whois/identify]_check function even if
1720 we are not router server.
1722 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Added --with-gmp configuration option. If set the GMP
1725 is always compiled in the SILC source tree. If not set then
1726 it is checked whether the system has the GMP3 installed. If
1727 it has then the GMP won't be compiled (the system's headers
1728 and library is used), if it doesn't have it then the GMP is
1729 compiled in the SILC source tree.
1731 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Changed RSA private exponent generation to what PKCS #1
1734 suggests. We try to find the smallest possible d by doing
1735 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1736 not security fix but optimization.
1738 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Added new config entry [Identity] to fork the server and run
1741 it as specific user and group. A patch from Bostik.
1743 * Imported Dotconf configuration library into lib/dotconf.
1744 This will be used to create the SILC configuration files later.
1745 It will appear in the distsribution after this commit.
1747 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * A big code auditing weekend happening. Auditing code for
1750 obvious mistakes, bugs and errors. Also, removing any code
1753 Removed files for being obsolete:
1755 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1756 inline in the file lib/silcutil/silcbuffer.h)
1758 o lib/silcutil/silcbufutil.c (the header has inline versions)
1760 Changed code to fix possible error conditions:
1762 o The buffer formatting routines now check that the destination
1763 buffer really has enough space to add the data. This applies for
1764 both buffer formatting and unformatting
1765 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1766 unformatting was changed to accomodate following rules:
1767 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1768 sent to the function while XXX_*STRING will not allocate or copy
1769 the data into the buffer. Instead it sets the pointer from the
1770 buffer into the pointer sent as argument (XXX_*STRING used to
1771 require that the pointer must be allocated already). This change
1772 makes this whole thing a bit more consistent and more optimized
1773 (note that the data returned in the unformatting with XXX_*STRING
1774 must not be freed now). The routines return now -1 on error.
1776 o Tried to find all code that use buffer_format and buffer_unformat
1777 and added return value checking to prevent formatting and
1778 especially unformatting errors and possible subsequent fatal
1781 o Changed ske->x and ske->KEY to mallocated pointers in
1782 lib/silcske/silcske.h. Fixed possible data and memory leak.
1784 o Added return value checking to all *_parse* functions. Fixed
1785 many memory leaks as well.
1787 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1788 so that buffer overflows would not happen. All code now also
1789 checks the return value as it can fail.
1791 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Added reconnection support to server if the normal server looses
1794 its connection to the router (for example if router is rebooted).
1795 The server performs normal reconnection strategy implemented
1796 to the server. Affected file silcd/server.c.
1798 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Added new packet type SILC_PACKET_SET_MODE that is used to
1801 distribute the information about changed modes (for clients,
1802 channels and clients channel modes) to all routers in the
1803 network. Updated the protocol specification accordingly.
1805 Added functions into silcd/packet_send.c and
1806 silcd/packet_receive.c: silc_server_send_set_mode,
1807 silc_server_set_mode.
1809 Added new files silcmode.[ch] into lib/silccore that implements
1810 the encoding and decoding of Set Mode Payload. Added new type
1811 SilcSetModePayload. Moved the definitions of different modes
1812 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1814 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * Oops, a little mistake in server's connection authentication
1817 protocol. The protocol is not ended with FAILURE but with
1818 SUCCESS if the authentication is Ok. :) Affected file is
1821 * Implemented NICK_CHANGE notify handling in server in the file
1822 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1823 the local clients on the channel. After the changing nickname
1824 in router environment snhould work and the [<unknown>] nickname
1825 should appear no more.
1827 The silc_server_replace_id function that receives the Replace ID
1828 payload now sends the NICK_CHANGE notify type also in the file
1829 silcd/packet_receive.c
1831 * Changed WHOIS and IDENTIFY command to support the maximum amount
1832 of arguments defined in protocol specs (3328 arguments). This
1833 fixed a bug that caused problems when there were more than three
1836 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * Added extra parameter, command identifier, to the
1839 silc_client_send_command so that explicit command identifier
1842 Changed that ID list routines uses specific command identifier
1843 when sending WHOIS/IDENTIFY requests to the server so that they
1844 can be identified when the reply comes back.
1846 Affected files lib/silcclient/command.[ch],
1847 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1849 * Added `sender' argument to silc_server_packet_send_to_channel
1850 to indicaet the sender who originally sent the packet to us
1851 that we are now re-sending. Ignored if NULL. Affected file
1852 silcd/packet_send.[ch].
1854 * Added some server statistics support in silcd/server_internal.h
1855 SilcServerStatistics structure and around the server code. Also
1856 send some nice statistics information when client is connecting
1859 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Fixed channel ID decoding in server's JOIN command reply in
1862 silcd/command_reply.c
1864 * Fixed braodcasting of replace ID payload to not to send it if
1865 we are standalone server in silcd/packet_receive.c.
1867 * Fixed all channel message sending routines to not to send
1868 packets to clients that has router set, since they are routed
1869 separately in the same function earlier. Affects file
1870 silcd/packet_send.c and all channel packet sending functions.
1872 * In USERS reply, res_argv[i] are not allocated, the table
1873 is allocated. Thus changed that free the table, not its
1876 * In server's whois_check and identify_check if the client is
1877 locally connected do not send any WHOIS commands - they are not
1880 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Fixed some minor bugs in client when sending WHOIS command. The
1883 arguments was in wrong order.
1885 * Removed statis function add_to_channel from server in
1886 silcd/command.c that was previously used with the joining but
1889 * Tested USERS command in router environment successfully with two
1890 routers, two servers and two clients.
1892 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Reorganized the USERS command and command reply in client library
1895 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1896 When the command is given by user we register a pending command
1897 callback that will reprocess the command after the reply has been
1898 received from the server. When reprocessing the packet we then
1899 display the information. Thus, the USERS information is displayed
1900 now in the command callback instead of in the command reply
1901 callback. The processing of the command is same as previously
1902 when server has sent the command reply in the JOINing process.
1904 * Added to USERS command in silcd/command_reply.c to join the client,
1905 we didn't use to know about, to the channel after we've created
1906 a client entry for it. Also, for clienet we did know already still
1907 check whether it is on the channel or not and add it if not.
1909 * Removed silc_server_command_join_notify as the function and its
1912 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Changed the client's pending command handling to the same as the
1915 server's pending command handling. It is also now possible to
1916 execute command reply functions from other command reply
1917 function as the function callbacks for commands and command
1918 replies are one and same. The pending commands are not static
1919 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1920 in client connection context. Thus, pending commands are server
1921 connection specific as it is convenient.
1923 Changed the function silc_client_command_pending and
1924 silc_client_command_pending_del and added new function
1925 silc_client_command_pending_check. Removed the
1926 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1929 * Added cmd_ident, current command identifier, to the client
1930 connection context in lib/silcclient/client.h to keep track on
1931 command identifiers used in command sending. Client's command reply
1932 function handling now supports the mandatory command identifiers.
1934 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1935 funtions in client to fully support pending command callbacks.
1937 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1938 as one of the arguments to the application in the command reply
1941 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1942 before first releasing SILC but came back. Now it is removed again
1943 and should come back nomore. The FORWARDED flag was used only
1944 by the JOINing procedure by forwarding the command packet to router.
1945 Now, the JOINing procedure has been changed to more generic (due
1946 to various router environment issues) and FORWARDED is not needed
1947 anymore for anything. The protocol specification is yet to be
1950 Now, removed silc_server_packet_forward from server and the flag
1951 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1953 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Renamed NAMES command to USERS command. The NAMES was named that
1956 due to historical reasons. Now it is renamed. Also, rewrote
1957 parts of the USERS command. The nickname list is not sent anymore
1958 by the server. Only Client ID and mode lists are sent in the USERS
1959 command. Changed this also to the protocol specification.
1961 The client now resolves the names and stuff after it receives
1962 the USERS list from the server when joining to the channel.
1964 * WHOIS and IDENTIFY commands has been changed to support multiple
1965 Client ID's per command. One can now search for multiple users
1966 in the network by sending only one WHOIS or IDENTIFY command.
1967 Changed the code and the protocol specifications.
1969 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1970 uses silc_server_command_whois_parse to parse the request. */
1972 * If normal server, do not parse the WHOIS and IDENTIFY requests
1973 before sending it to the router. Saves some time.
1975 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Fixed JOIN command on client library. Wrong number of arguments
1978 used to crash the client.
1980 * Added silc_server_channel_has_global function to check whether
1981 channel has global users or not.
1983 * Added silc_server_channel_has_local function to check whether channel
1984 has locally connected clients on the channel.
1986 * The silc_server_remove_from_one_channel now checks whether the
1987 channel has global users or not after given client was removed from
1988 the channel. It also checks whether the channel has local clients
1989 on the channel anymore. If it does not have then the channel entry
1990 is removed as it is not needed anymore.
1992 * The silc_server_notify now checks on JOIN notify whether the joining
1993 client is one of locally connected or global. If it is global then
1994 the channel has now global users on the channel and that is marked
1995 to the channel entry. Also, it now saves the global client to
1996 global list who is joining and JOINs it to the channel. This is
1997 for normal server, that is.
1999 Changed silc_server_send_notify_on_channel,
2000 silc_server_packet_relay_to_channel and
2001 silc_server_packet_send_to_channel check if we are normal server
2002 and client has router set (ie. global client) do not send the
2003 message to that client, as it is already routed to our router.
2005 * Implemented LEAVE notify type handling in silc_server_notify
2008 * Tested LEAVE command in router environment successfully. Tested
2009 with two routers, two servers and two clients.
2013 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2015 * Implemented SIGNOFF notify type handling in silc_server_notify
2018 * silc_server_remove_id now removes the client entry from all channels
2019 it has joined and thusly sends SIGNOFF notify type.
2021 * Rewrote the NAMES list generation in server by removing two excess
2022 loops. The lists are created now inside one loop.
2024 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * silc_server_remove_channel_user checks now also global list
2027 for channel and client.
2029 * silc_server_new_channel_user checks now both local and global
2030 list for channel and client. Fixed a bug in client id decoding.
2031 Used to decode wrong buffer.
2033 * silc_server_channel_message checks now both local and global
2034 list for channel entry.
2036 * Tested channel joining (hence JOIN) in router environment
2037 successfully. Tested with two routers, two servers and two
2040 * Tested channel message sending in router environment successfully.
2042 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Added silc_server_save_channel_key into server.[ch] to save the
2045 received channel key in Channel Key payload processing. It is
2046 also used in JOIN command reply handling.
2048 Equivalent function silc_client_save_channel_key added into
2049 client.[ch] into client library.
2051 * Changed JOIN command reply to send information whether the channel
2052 was created or not (is existing already) and the channel key
2053 payload. Changed protocol specs accordingly.
2055 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2056 the request was sent by ID and not by nickname. Crashed on
2059 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2062 now correctly save the received data.
2064 * silc_server_free_sock_user_data now notifies routers in the
2065 network about entities leaving the network.
2067 At the same time implemented functions silc_server_remove_id
2068 and silc_server_send_remove_id to receive and send REMOVE_ID
2069 packets. The packet is used to notify routers in the network
2070 about leaving entities. The ID removed will become invalid in
2073 * Added function silc_idlist_del_server into server. Removes and
2074 free's server entry from ID list.
2076 * silc_server_private_message function now checks, if we are router,
2077 that the destination ID really is valid ID, naturally.
2079 * In router when NEW_ID packet is received (for new client) the
2080 hash of the Client ID is saved in the ID Cache but the
2081 client->nickname is set to NULL, instead of putting the hash
2084 IDENTIFY command now also checks that client->nickname must be
2085 valid. If it is not if will request the data from the server who
2086 owns the client. Added new function
2087 silc_server_command_identify_check.
2089 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2090 to set the command to already allocated Command Payload.
2092 * Tested private message sending in router environment with two
2093 routers, two servers and two clients. Fixed minor bugs and now
2096 * Fixed segfault from client's NAMES command. Used to crash if
2099 * Forwarded packets must not be routed even if it is not destined
2100 to the receiver. Changed server code comply with this.
2102 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Added `require_reverse_mapping' boolean value to ServerParams
2105 structure. If TRUE (not default) the server will require that
2106 the connecting host has fully qualified domain name.
2108 If the reverse mapping is not required and hostname could not be
2109 found the IP address is used as hostname.
2111 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Implemented version string checking to both client and server.
2114 The check is incomplete currently due to the abnormal version
2115 strings used in development version of SILC.
2117 * Changed all command functions in server to use the new
2120 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Changed char *data to unsigned char *data in ID Cache system to
2123 support binary data as ID Cache data. Changed code to support
2124 binary data in lib/silccore/idcache.c.
2126 * Renamed silc_server_packet_relay_command_reply to
2127 silc_server_command_reply as it is normal packet receiving
2128 function. Rewrote the function to accept command replys for
2129 servers and not only for clients.
2131 * Mark remote router always as registered server if we are connecting
2132 to it. Otherwise, commands sent by the router to us are ignored.
2134 * All ID List find routines now returns the ID Cache Entry pointer
2135 as well if requested.
2137 * WHOIS command works now in router environment, tested with two
2138 routers, two servers and two clients.
2140 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2141 in router environment (as it is almost equivalent to WHOIS) but
2142 hasn't been tested thoroughly. Added new functions:
2144 silc_server_command_identify_parse
2145 silc_server_command_identify_send_reply
2146 silc_server_command_identify_from_client
2147 silc_server_command_identify_from_server
2149 * Disabled route cache adding because adding two different ID's with
2150 same IP replaces the old cache entry thus giving wrong route.
2151 The entry->router->connection is always the fastest route anyway
2152 so route cache may not be needed. Of course, new routes maybe
2153 established after receiving the ID when the entry->router->connection
2154 might not be anymore the most optimal.
2156 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Add route cache for received ID for fast routing.
2160 * Added silc_server_packet_route to route received packet on router
2161 that is not destined to us.
2163 * Renamed silc_server_get_route to silc_server_route_get.
2165 * Added id_string and id_string_len fields into SilcServer to
2166 include encoded ServerID for fast comparing without excess
2167 encoding of the ID's.
2169 * Cleaned up WHOIS command on server side. Added following static
2172 silc_server_command_whois_parse
2173 silc_server_command_whois_check
2174 silc_server_command_whois_send_reply
2175 silc_server_command_whois_from_client
2176 silc_server_command_whois_from_server
2178 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2179 arguments in command replies. All command functions should be
2180 updated to use this macro.
2182 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Minor typo fixes on command reply handling on server.
2186 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Added silc_server_command_add_to_channel internal routine to add
2189 the client to the channel after router has created the channel and
2190 sent command reply to the server.
2192 * Added generic silc_server_send_command to send any command from
2195 * Use static buffer with ID rendering instead of duplicating data.
2197 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Fixed a channel user mode bug when joining to a channel server gave
2200 everybody channel founder rights, oops.
2202 * We mark ourselves as the router of the incoming server connection
2203 if we are router ourselves. This way we can check in some packet
2204 sending functions whether it is locally connected server. For
2205 incoming router connections we put NULL.
2207 * For router sending packets locally means now always sending the
2208 packet cell wide; to local clients and local servers. For normal
2209 server sending packet locally means sending it to only local
2212 * Fixed the JOIN command to really work in router environment. If the
2213 channel is created it is always created by the router. Router is
2214 also responsible of making the initial joining to the channel,
2215 sending JOIN notify to the sending server and distributing
2216 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2217 does not exist server doesn't do anything else but forward the
2218 command to the router which performs everything.
2220 * Added silc_server_send_channel_key function to send the Channel Key
2223 * Added silc_server_create_channel_key to create new channel key. The
2224 channel key is now re-generated everytime someone joins or leaves
2225 a channel, as protocol dictates. Note: channel->key_len is the
2228 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2231 packet_receive.[ch] to separate packet sending and receiving
2232 routines. The server.[ch] now includes everything else including
2233 actual packet processing (writing and reading data) and other
2236 Renamed silc_server_private_message_send_internal to
2237 silc_server_send_private_message. The routine is still though
2238 used only to relay private messages as server does not send
2239 private messages itself.
2241 Renamed silc_server_new_channel to silc_server_create_new_channel
2242 and added new function sicl_server_new_channel that handles the
2243 incoming New Channel packet. Added also new sending function
2244 silc_server_send_new_channel to send New Channel Payload.
2246 * Added new function silc_server_notify to process incoming notify
2247 packet to the server/router. Server may then relay the notify
2248 to clients if needed.
2250 * Added new function silc_server_new_channel_user to process incoming
2251 New Channel User packet. Router will redistribute the packet and
2252 send JOIN notify to its local clients and locally connected servers
2253 if needed. Normal server will send JOIN notify to its local client
2254 on same channel when received this packet. Added also corresponding
2255 sending function silc_server_send_new_channel_user to sent the
2258 * Added boolean route argument to send_notif_to_channel and
2259 packet_send_to_channel functions to attempt to route the packet
2260 if it is TRUE and send only locally if it is FALSE.
2262 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * silc_server_replace_id now broadcasts the received replace ID
2265 packet if it is not broadcast packet already. The router must
2266 broadcast to inform other routers about changed ID.
2268 * Added backpointer to server's router into SilcServer context in
2269 silcd/server_internal.h.
2271 * Fixed silc_server_packet_broadcast to send correct broadcast
2274 * The channel key is now distributed to the local client as soon
2275 as it is received from the router (in router environment) so that
2276 no other packet may be sent for the channel until client has
2279 * silc_server_remove_channel_user now broadcasts the received
2280 Remove Channel User packet if it is not broadcast packet already.
2281 The router must broadcast to inform other routers about removed
2284 * Added users field into SilcPacketContext that is a reference count
2285 of the context. One can increase the reference count by calling
2286 silc_packet_context_dup which is now changed to just increase the
2287 reference count instead of duplicating the data. The reference
2288 count is decresed by calling silc_packet_context_free that will
2289 free the data after the reference count hits zero.
2291 For now on the packet context and everything allocated into it
2292 (including the raw packet from network) must be freed by calling
2293 the new silc_packet_context_free function. Added also new function
2294 silc_packet_context_alloc that must be used now to allocate the
2295 context. This also means that if a routine is asynchronous from
2296 silc_[client/server]_packet_parse_type the packet context must
2297 be duplicated by calling silc_packet_context_dup. Otherwise it
2298 gets free'd after silc_[client/server]_packet_parse_type returns.
2299 Also, one must remember that if packet is duplicated then its
2300 reference count must be decresed by calling the free function as
2301 many times as it was duplicated.
2303 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2304 from both client and server.
2306 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Made joining to a channel working in router environment.
2310 * Cleaned up JOIN command on server side and create function
2311 silc_server_command_join_channel internal routine to make the
2314 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Changed silc_command_pending list to SilcDList. Also, added
2317 `ident' field to SilcServerCommandPending structure to identify
2318 the reply and to call correct callback.
2320 Added silc_server_command_pending_check function to replace the
2321 corresnponding macro. The silc_command_pending list is not
2324 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2325 to set identifier to previously allocated Command Payload. It
2326 is used to set identifier for command when resending Command
2329 * Added silc_command_payload_encode_payload to encode Command
2330 Payload buffer from SilcCommandPayload structure.
2332 * Added silc_argument_payload_encode_payload to encode Argument
2333 payload buffer from SilcArgumentPayload structure.
2335 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Changed WHOIS command to support router connection on server side.
2338 The whois request is always sent to router unless the server is
2339 standalone server. After server has received the reply from the
2340 router will it send the reply to the client.
2342 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2343 broadcast received broadcast packet. The function is used only
2344 by router. The broadcast packet is always sent to the router's
2347 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2348 render given ID to printable string, for log files for example.
2350 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Made basic router to router connections working. At least they
2353 can now connect to each other but nothing really works the way
2354 they are supposed - yet.
2356 * Added new initiator token to RouterConnection configuration
2357 file in silcd/serverconfig.[ch]. It is used to tell whether we
2358 are the initiator to the remote router or whether we'll expect
2359 the other end to connect.
2361 * Moved registering of listener task to silc_server_init, hence
2362 the server starts listenning as soon as it is run, even if it
2363 does not have connections to other routers. Let's see how well
2366 * Changed default connection retry timeouts for more suitable in
2369 * Removed cipher and such arguments from silc_idlist_add_client
2370 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2371 Added new function silc_idlist_add_data to add the keys and stuff
2374 * Added SilcIDListData structure and added it to SilcClientEntry
2375 and SilcServerEntry as their first field in the structure. This
2376 way we can explicitly cast the ID entries to the SilcIDListData
2377 structure and get common data for the entries. In past, we had
2378 to first check what type of connection it is and then cast it to
2379 correct ID entry type. Now, we can directly cast the opaque
2380 pointer to the SilcIDListData (no matter what ID entry it actually
2381 is) and get the data needed.
2383 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2386 in some circumstances even if threre were timeout tasks, though not
2387 IO tasks, but tasks anyway. Now fixed.
2389 * Defined SilcServerConnection structure to hold connection specific
2390 stuff about directly connected servers and routers. The definition
2391 is currently in silcd/server_internal.h. I thought about having
2392 a bit more important role fro this struct but for now it is used
2393 only when connecting to other server (or router actually).
2395 * Added connecting retry support in server when connecting to
2396 router(s). The retry feature implement exponential backoff
2397 algorithm. Also, added SilcServerParams structure to hold default
2398 parameters for server. For now, it include these retry settings
2399 and are hard coded. After server is moded to be as Silc Server
2400 Library this structure will be more important.
2402 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Changed client librarys channel->clients table to SilcList and
2405 changed code accordingly.
2407 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Changed client's channel table to SilcList and changed code
2410 accordingly. Also changed SilcChannelClientEntry to include back-
2411 pointer to the channel so that client entry can use that structure
2412 as list as well and we have fast cross-reference to the channel.
2413 This change dramatically decreased the complexity of channel
2414 handling with client entry and vice versa (removed one extra
2415 loop when searching for channel entry from many functions).
2417 * Changed server->sim from table to SilcDList and changed code
2420 * NAMES command can now be used from user interface. It will show
2421 the user list on the channel, neatly.
2423 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2424 Code now saves realname of the user if it becomes available.
2426 * Renamed configure.in to configure.in.pre and made ./prepare
2427 script to automatically add correct version string to
2428 configure.in which it creates from configure.in.pre.
2430 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * NAMES command reply now shows users mode with the nickname when
2435 * Moved silc_client_ch[u]mode[_char] functions from
2436 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2437 place sucks, they are utility functions and should be in some
2440 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2442 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2445 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Added TRQ (efficient deque and list library) into lib/trq. This is
2450 a very good list library that is currently used in the SILC. Defined
2451 SilcList API over the library because I didn't like the API very
2452 much. See lib/trq/silclist.h for the API and examples of how to
2453 use the API. Fixed various places in the code to use the new
2454 SilcList API. The SilcList is meant for lists that has a structure
2455 already defined as a list. It is not suitable to add just some
2456 context to the list (in TRQ, the context is the list actually).
2458 So, I defined SilcDList that can be used for the purpose where
2459 predefined list structure does not exit. This can be used as
2460 such list. Now some context just can be added to the SilcDList.
2461 Currently this list is not used in the SILC just yet, though there
2462 are a lot places where this can replace dynamically allocated
2463 tables and I will fix these places, later, to use SilcDList.
2464 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2465 and use TRQ internally).
2467 Also fixed some annoying warning messages that the original TRQ
2468 code generated. Also minor changes to TRQ's Makefile.in.
2470 * Added support for querying by Client ID to both WHOIS and
2471 IDENTIFY commands into server, as required by the protocol.
2473 * Removed method function pointers from SilcBuffer structure. They
2474 weren't used to anything and just increased the context size for
2475 no good reason. This change also made silc_buffer_alloc and
2476 silc_buffer_free functions inline functions.
2478 * Disabled command flooding detection support until it's fixed so
2479 that it accepts commands in but does not execute them more than once
2482 * Added silc_net_localhost(), to return local hostname, into
2483 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2484 that must be initialized before calling silc_client_init.
2486 * Added new function: silc_server_send_notify_on_channels to send
2487 notify messages to all channels client has joined. It is assured
2488 that the message is sent only once per client.
2490 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2491 lib/silcutil/silcutil.[ch] as silc_format function. The new
2492 function is generic and is used by server as well, not only by
2493 the logging routines.
2495 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2496 the provided version string was not acceptable. Added new function:
2497 silc_ske_check_version into lib/silcske/silcske.h. The function
2498 must be implemented by the application (client or server) and it
2499 does not reside in the SKE library. The function checks the version
2500 string remote end sent.
2502 * Added back pointers (to opaque context and to SilcSocketConnection)
2503 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2505 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2506 duplicate packet context structure.
2508 * Changed `notify' client operation to send same arguments as client
2509 receives from server except for ID's. ID's are mapped to correct
2510 ID entry and that is returned. Also, if channel entry is not sent
2511 by server but the notify is for channel the channel entry is sent
2512 to application (otherwise application doesn't know that it is for
2513 channel (library gets it from packet's Destination ID)).
2515 * Added silc_client_remove_from_channels into client library to
2516 remove a client from all channels it has joined to. Used when
2517 received SIGNOFF notify from server. Added also new function
2518 silc_client_replace_from_channels to replace old ID entry with
2519 new ID entry on all channels. Used when received NICK_CHANGE
2522 * Fixed ID Cache list handling in silc_idlist_get_client in
2523 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2524 to get (or query) client by ID.
2526 * Updated TODO list.
2528 * Added connection authentication status message defined by the
2529 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2530 support for these into the code in client and server side.
2532 * Added generic function silc_client_send_command to send any command
2533 with variable argument list. Application should use this function
2534 to send commands if the command functions provided by the library
2535 does not suite for the application's user interface needs.
2537 * Added new `failure' client operation. Application is notified about
2538 received failure packet if client is executing a protocol. In this
2539 case the protocol's execution has failed.
2541 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2542 is required by the protocol.
2544 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2545 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2548 * Added status flag to SilcSKE object to indicate realtime status
2549 of the SKE protocol.
2551 * Application receives now exactly same command reply arguments as
2552 the library receives from server. However, if ID is received the
2553 corresponding ID entry is returned to the application (eg. Client
2554 ID is mapped to correct SilcClientEntry entry and that is returned).
2555 Changed command_reply client operation due to this change.
2557 * Changed all ID's in commands and in command replys as ID Payloads.
2558 Change affected both client and server side codes.
2560 All ID's sent in SILC network (with execption of ID's in SILC
2561 Packet header) are sent in ID Payload to support variable length
2564 * Server now notifies nick changes and notifies all clients on
2565 the channels about the new nickname (about the new Client ID,
2568 * Implemented CMODE command to change channel modes. Supports all
2569 channel modes defined by the protocol specs except ban and invite
2570 lists. (Also, private channel key mode is supported but support for
2571 setting private channel key in client is missing, thus, this mode
2572 has no effect on client side (except that server requires that the
2573 client uses private channel key and normal channel traffic does not
2576 Also, invite mode works per se, but INVITE command does not work
2577 yet correctly, so you can set channel as invite only channel but
2578 inviting clients to the channel does not work (it is yet to be
2579 thought what's the best way to do it).
2581 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2582 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2583 Implemented CUMODE command to change user's mode on the channel.
2584 Supports all modes defined by the protocol specs.
2586 * Added NAMES command reply to return users modes on the channel.
2588 * Removed unnecessary and slow ciphers from lib/silccrypt.
2590 * Set SO_KEEPALIVE option to connection sockets by default.
2592 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2594 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2595 redefined the Notify Payload into protocol specs.
2597 * Added silc_id_payload_parse_id to get ID directly from raw
2600 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2603 accept searching by Client ID as well.
2605 * Added support for LEAVE and SIGNOFF notify types in client library.
2607 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2608 to parse ID Payload from raw data.
2610 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added flags parameter into silc_ske_assemble_security_properties
2613 function in lib/silcske/silcske.[ch].
2615 * Changed notify client operation to fit better for notify messages
2616 sent by server. The notify payload received from server is now
2617 passed to the application (after parsing it to SilcNotifyPayload).
2618 It is application's responsibility to retrieve the arguments
2619 from the payload and show the message the way it wants. The message
2620 sent by server is implementation specific.
2622 * Changed public keys to comply with the protocol specification.
2623 Old public keys are not supported anymore and are not compatible.
2625 * Removed nickname from Channel Payload as the latest draft removed
2626 it. The client must resolve the nickname from the NAMES command
2627 reply received when it joined the channel.
2629 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2631 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Fixed some errors in protocol specification drafts.
2635 * Created lib/silccore/silcnotify.c to implement Notify Payload
2636 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2637 generic payloads described by protocol specifications. The file
2638 includes implementations for ID Payload and Argument Payload.
2640 * Changed Command Payload implementation to use the new Argument
2641 Payload. Changed command_xxxx_payload to command_payload_xxxx
2642 to comply with SILC coding conventions.
2644 * Added suppport for Argument Payload handling in Notify Payload
2645 implementation as protocol requires it. Added the new support
2646 into server and client lib as well.
2648 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Added support for multiple nicknames on same channel. [n] is
2651 added locally to the nickname if there are more than one same
2652 nicknames on the channel.
2654 * Server now sends all nicknames that matched WHOIS request.
2655 Client also shows the list received from server.
2657 * Added TOPIC command to client side. User can now set and show
2658 current topic on channel.
2660 * Added MOTD command to client and server. Also, server sends the
2661 motd when client connects to the server.
2663 * Changed version strings to comply ISO 8601.
2665 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Fixed protocol error handling in client library. It should now
2668 cope even if the SKE fails for some reason.
2670 * Made new protocol specification drafts for submitting to IETF.
2672 * Implemented TOPIC command to server in silcd/command.c.
2674 * Added two new notify types into lib/silccore/silcnotify.h:
2675 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2676 notify nickname change and topic setting/change on a channel.
2678 * API change of command_reply operation in client library. The
2679 application gets now the status type received from server as well.
2681 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2685 * Cras fixed and optimized the packet handling even further and
2686 it should work now. Minor change to the prototype of function
2687 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2689 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added new function into lib/silcutil/silcschedule.[ch]:
2692 silc_schedule_with_fd to select() a specified fd. The function
2693 returns after timeout expires or data arrives or goes. The
2694 function is used by packet routines to wait that all data is
2695 received from network.
2697 * Fixed data reading from network in lib/silccore/silcpacket.c.
2698 The code now assures that all data is read from the fd and then
2699 continues packet processing. This was a bug fix since the code
2700 used to drop some data in some circumstances.
2702 * Added new function into lib/silcclient/client.[ch]:
2703 silc_client_start_key_exchange to start key exchange after
2704 connection has been established to server. The code internally
2705 now uses this funtion but its main purpose was to provide it
2706 for applications that perform their own connecting. After
2707 application has created a connection it merely calls this
2708 function to start the key exchange between client and server.
2709 The library takes care of everything else after that.
2711 Updated also lib/silcclient/README to explain the usage of
2714 * Do not send to application information that connection has
2715 been established. Application gets notified it by connect
2718 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Applied cras's patch to add silc_schedule_one function. The
2721 function runs scheduler once and returns.
2723 * Fixed the scheduler after cras messed it up. The timeout
2724 handling works now as it's supposed to work.
2726 * Added into lib/silccore/ silcnotify.h to include notify
2727 message types support. Changed silc_server_send_notify*
2728 functions, in server.[ch], to support those new notify types.
2729 Added the support for the notify types into client library,
2730 as well. Added new notify client operation into ops.h in
2733 * Changed silc_server_packet_send_to_channel to send normal
2734 packets instead of just channel message packets. The function
2735 is now used to send the notify packets to channels. It is not
2736 used to send channel message packets anymore, as server never
2739 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2740 va_arg()s as it seems to require it nowadays. I guess, if SILC
2741 is compiled with older va_arg() the new code should work anyway.
2743 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Splitted core library. Core library (lib/silccore) includes
2746 now only SILC protocol specific core (and common) components.
2747 Created new utility library (lib/silcutil) that includes more
2748 generic purpose stuff. The stuff for util library was taken
2749 from the old core library. This was minor and easy split.
2751 * Created SILC Client Library (lib/silcclient) that includes
2752 implementation of the SILC client without user interface. This
2753 was major move from silc/ directory. The code has been changed
2754 so that it is transparent towards the user interface. The
2755 silc/ directory includes now the same user interface as before
2756 and it uses the new client library. Read lib/silcclient/README.
2757 Basicly, the client library performs everything else related
2758 to SILC except user interface handling. Also, configuration
2759 files are considered to be part of user interface and library
2760 does not handle them.
2762 This change also changed a lot of structures, function naming etc.
2763 Most important change was that SilcClientWindow object was
2764 renamed to SilcClientConnection in the client library. Created
2765 also new file lib/silcclient/ops.h. Also added new files
2766 silc/local_command.[ch] and silc/client_ops.[ch].
2768 All these changes were made to make it easier for user interface
2769 designers to create what ever user interface for the SILC client
2772 It is also expected that the server will be moved to lib
2773 directory as well and SILC Server Library will be created;
2774 sometimes in the future.
2776 * Removed Local commands from lib/silccore/silccommand.h as
2777 they are application specific and new client library does not
2778 handle any of those anymore.
2780 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2781 old client implementation in silc/.
2783 * Added support for callback functions in SILC_LOG_* macros.
2784 Application can now set its own callbacks that will be called
2785 instead of using the default functions that will always print
2786 the debug messages to stderr (or stdout). Also, debugging can
2787 now be disabled by setting silc_debug to FALSE and re-enabled by
2788 setting it to TRUE. Note, that logging will still work even
2789 if debugging is disabled.
2791 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2792 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2793 silc_log_reset_debug_callbacks.
2795 * To enable debugging in silc client one must give now -d
2796 option on command line.
2798 * Changed silc_schedule_init to automatically allocate task queues
2799 if they are not allocated before calling it.
2801 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Added GMP 3.1 into math library.
2805 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2808 a channel in SILC network. The packet is used by servers and
2809 routers to notify other routers that user has left a channel.
2810 This little feature was missing until now. Added the feature
2811 to protocol specification as well.
2813 Added functions: silc_server_send_remove_channel_user and
2814 silc_server_remove_channel_user into server.[ch].
2816 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2817 lib/silccore/silcpacket.h. However, they are not implemented
2820 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Fixed joining to a channel and sending channel messages
2823 between server and router. The channel message sending should
2824 now work inside a cell.
2826 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Fixed the private message sending between server and router.
2829 The private message sending should now work inside a cell.
2831 * Added silc_server_replace_id into server.[ch] to replace
2832 existing ID in the SILC network.
2834 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2835 and silc_idlist_replace_server_id into idlist.[ch] in server.
2837 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Fixed the server to server connections. Server can again now
2840 connect to router. Router to router connections probably does
2843 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Added dynamic protocol registering support. Now protocols can
2846 registered and unregistered on the fly. Patch by cras.
2848 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Added lib/contrib directory to hold routines that some platforms
2851 don't have but are needed by SILC.
2853 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2854 into lin/contrib to provide getopt() and getopt_long() for
2855 those who don't have it.
2857 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added AWAY command to client. When away message is set and
2860 client receives a private message packet the client automatically
2861 replies to the sender with the away message.
2863 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2864 bug seemed to be the cause of recent problems when compiling
2867 * Added version detection support to SKE protocol specification
2868 and added the new changes to the SKE implementation as well.
2869 There were other minor changes in the SKE protocol as well.
2871 Many changes in lib/silcske/silcske.[ch] and in
2872 lib/silcske/payload.[ch].
2874 * Added ^U functionality, clear input line. Patch from cras.
2876 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Mainly small bugfixes on core library. Fixed some debugging
2879 logging and buffer overflow in silclog.c.
2881 * Updated config.sub and config.guess on the distribution tree.
2883 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Added command lagging support in server. Client may execute
2886 commands now only once in two seconds.
2888 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Optimized packet reception. MAC computation and checking is now
2891 also more optimized. A lot previously duplicated code is now
2892 used as generic by both client and server.
2894 * Fixed key pair generation in clientutil.c
2896 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Added into lib/silccore/silcbufutil.[ch] new function;
2899 silc_buffer_realloc.
2901 * Moved generic packet sending/encryption functions to
2902 lib/silccore/silcpacket.[ch] from client and server. Some
2903 rewriting of the functions.
2905 * Moved all generic packet reception/decryption functions to
2906 lib/silccore/silcpacket.[ch] from client and server. The
2907 packet processing is now much cleaner in both client and server.
2908 These were major changes in both client and server.
2910 * Created many common functions in server to do packet sending.
2911 Previously code were duplicated a lot, this has been removed
2914 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Rewrote major parts of the ID cache system. Don't know
2917 whether it is better now or not but at least the API is more
2920 * Major rewrite on ID cache stuff on client because of the ID
2921 cache API changes. Added idlist.c to client.
2923 * Also major rewrite on ID cache stuff on server as well.
2924 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2925 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2926 in hand, instead they are all put into the ID cache system now.
2927 All server_idlist_* routines uses ID cache now instead of
2928 traversing its own lists (those lists does not exist anymore).
2929 SilcIDList though still exists. Also, SilcXXXEntry's are
2932 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Finally made the SKE implementation compliant to the protocol
2935 specification. All mp integers are now binary encoded as
2936 opposed being HEX encoded.
2938 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2941 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2942 functions: silc_[encode/decode]_pem. Also added function
2943 silc_encode_pem_file to PEM encode with newlines ('\n') for
2946 * SILC public keys are now encoded either PEM or binary. Same
2947 option is for private keys as well. By default private keys
2948 are binary encoded and public keys PEM encoded. Silly HEX
2949 encoding were removed.
2951 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2952 function to create fingerprints.
2954 * Fixed a bug in SHA1; does not change the original data anymore.
2956 * Partly implemented INFO command on client and server side.
2957 Fixed CLEAR command. Changes to SERVER command; show current
2958 server(s) when giving command without arguments. Added
2959 VERSION command to client.
2961 * Added check to server that unregistered connections cannot
2962 execute commands (unless it is specificly allowed).
2964 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Fixed screen refresh.
2968 * Fixed channel joining bug from client. On some circumstances
2969 client tried to join to a channel it had already joined.
2971 * Added public key verification process into client's protocol.c.
2972 The client now verifies the public key from user and saves
2973 it into ~./silc/serverkeys/ directory.
2975 Added into: clientutil.[ch]: silc_client_verify_server_key.
2977 * Changed SKE protocol's silc_ske_initiator_finish function
2978 to accept callback function that verifies the received public
2979 key. Removed old silc_ske_verify_public_key function.
2981 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2984 silc_pkcs_private_key[_data]_set.
2986 * Made the password and public authentication more cleaner in
2987 server's protocol.c.
2989 * Removed historic and obsolete protocol `channel_auth' from
2990 both client and server.
2992 * Removed wrong way of sending command status messages from
2993 server to client in server's command.c. The old way violated
2994 protocol specification.
2996 Changes to silccore/silccommand.[ch]: removed
2997 silc_command_encode_status_payload -> not needed anymore,
2998 changed silc_command_encode_payload_va to accept extra
2999 argument on variable argument list. The argument type must
3000 now be provided to the function. Also, added new function:
3001 silc_command_encode_reply_payload_va which is same as
3002 normal command_encode_payload_va except command status type
3003 is provided as extra argument.
3005 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Added ~./silc directory handling. The directory includes the
3008 public and private keys for the client.
3010 Added silc_client_check_silc_dir, silc_client_create_identifier
3011 and silc_client_load_keys.
3013 * Implemented SILC protocol compliant public key. Added public
3014 and private key saving to and loading from files.
3016 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3017 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3018 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3019 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3020 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3022 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3023 silc_pkcs_load_[public/private]_key.
3025 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Added silc_server_get_route (route.[ch]) to get connection
3028 data for the fastest route for given ID.
3030 * Implemented INVITE command on client and server. The command
3031 were re-defined in the SILC Protocol Specification and the
3032 implementation now complies with the specification.
3034 * Implemented PING command on client and server.
3036 * Implemented NAMES command on client and server. The server side
3037 supports currently only normal server not router server yet.
3038 Some changes to NAMES definition in SILC protocol specification.
3040 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Implemented LEAVE command on client and server.
3044 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3045 again. This change was made to the protocol as well. Server
3046 should not violate the protocol specification anymore.
3048 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3051 was tested. SOCKS4 was not but should work anyway.
