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

49 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
52 int64 of at least the xintXX size. If void * is less that 4
53 bytes uint32 * will be used. Defined bool as boolean.
55 * Changed _ALL_ unsigned long and unsigned int to uint32,
56 unsgined short to uint16 in the source tree.
58 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
59 not handle clients that has entry->data.registered == FALSE.
60 They are not in the network anymore. Affected file is
63 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Implemented the sending of the SERVER_SIGNOFF notify in the
66 server. Affected file is silcd/server.c.
68 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
69 Added also silc_notify_payload_encode_args into the
70 lib/silccore/silcnotify.[ch].
72 * Implemented ther SERVER_SIGNOFF notify handling in the server.
73 Affected file silcd/packet_receive.c.
75 * Implemented the SERVER_SIGNOFF notify handling in the client
76 library. Affected file lib/silcclient/client_notify.c. Also,
77 implemnted the printing of the SERVER_SIGNOFF info to the
78 application. Affected file silc/client_ops.c.
80 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
81 if the deleting was successful. Affected file silcd/idlist.[ch].
83 * Added support for public key authentication in the connection
84 authentication protocol in the client library. Affected file
85 lib/silcclient/protocol.c.
87 * Changed the server's silc_idlist_get_clients_by_* interface
88 to support already allocated array so that new entries may be
89 added to pre-allocated array. Affected file silcd/idlist.[ch].
90 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
93 * All command reply functions in the server now calls the
94 pending command callback even if error occured. This way the
95 error will be delivered to the client as well. Affected files
96 silcd/command.c and silcd/command_reply.c.
98 * Fixed INFO command to return local server's info if no server
99 was provided. Affected file lib/silcclient/command.c.
101 * Removed RESTART command for good. Updated the code and the
104 * Rewrote parts of the task system. It is a bit simpler now.
105 Removed unsued task priorities. The affected files are
106 lib/silcutil/silctask.[ch].
108 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Moved the USERS printing from the library to the application.
111 Affected files lib/silcclient/command.c and silc/client_ops.c.
113 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Added channel key re-key support. The re-key is perfomed
118 only by the router and is done once in an hour. Added `rekey'
119 field to the SilcChannelEntry in the server. Affected files
120 silcd/server.c and silcd/idlist.h.
122 * Added silc_task_unregister_by_context into the file
123 lib/silcutil/silctask.[ch].
125 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Added SILC_UMODE_GONE mode to indicate when the client is not
128 present in the SILC network. Added also support to the local
129 command AWAY that will set this mode. Added support of showing
130 "xxx is gone" in WHOIS command. The USERS command shows the
133 * Fixed setting server and router operator privileges in the
134 server's UMODE command. Affected file silcd/command.c.
136 * Merged the SKE KE1 and KE2 payloads into one payload. The
137 new KE payload is equivalent to the old KE2 payload.
139 Cleaned up the SKE Start Payload parsing. It now uses the
140 simple buffer unformatting to do the parsing. A lot faster
143 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
144 to the SKE that is used to indicate whether both of the SKE
145 parties should perform authentication. By default only the
146 responder performs authentication. By setting this flag also
147 the initiator must do authentication. By default it is unset
148 since in normal SKE case, client to server connection, only
149 the responder should do authentication. When doing SKE between
150 two clients both should perform authentication. Updated the
151 code and the protocol specs.
153 * A little fix to IDENTIFY command in the server. Search the
154 client first by hash not nickname. Affected file is
157 * Fixed the silc_client_close_connection to support closing
158 the client to client connections wihtout deleting too much
159 data. Affected file lib/silcclient/client.c.
161 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
162 are received if protocol used to be active but is not anymore
163 the application would crash due to NULL pointer dereference.
164 Affected files silcd/server.c and lib/silcclient/client.c.
166 * Added `hash' field to the SilcClientConnection to include
167 the hash function negotiated in the SKE protocol.
169 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
170 to set the channel founder authentication data. A client can
171 claim the founder rights later by providing the authentication
172 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
173 This way the channel founder can regain the channel founder
174 privileges even it is left the channel. This works only on
175 local server and the client must be connected to the same
176 server to be able to regain the founder rights. Updated the
177 protocol specs accordingly.
179 Added support to the CMODE command in the client to set the
180 founder auth data. Read the README to see how to set it.
182 Added support to the CUMODE command to claim the founder
183 rights. Read the README to see how to do it.
185 Added support for the founder authentication to the Channel
186 Entry in the server. Affected file silcd/idlist.h.
188 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
189 server's CMODE command. Affected file silcd/command.c.
191 * Added the following new functions into lib/silccore/silcauth.[ch]:
192 silc_auth_get_method and silc_auth_get_data.
194 * The server now saves the remote hosts public key to the
195 SilcIDListData pointer. Affected file silcd/protocol.c.
197 * The normal server now does not remove the channel entry from
198 the cache if the founder authentication data is set. It used
199 to remove it if the founder was the last one on the channel on
200 the server and left the channel. The auth data is saved and
201 if the channel is re-joined later the old entry is used with
202 the old auth data. Affected files silcd/command_reply.c and
205 * Removed the `pkcs' field from the SilcIDListData structure
206 in the server; it is not used. Affected file silcd/idlist.h.
208 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Fixed packet processing on slow links. Partial packets were
211 never re-processed because the incoming data buffer was cleared
212 by the application. Application must not directly clear the
213 sock->inbuf, the packet processing routines handle it. Fixed
214 this in client library and in server.
216 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Fixed the WHOIS and IDENTIFY send reply function to really
219 check whether to send list or just one entry. Affected file
222 * Cleaned up the LEAVE command's channel key distribution. The
223 affected file silcd/command.c.
225 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
226 can enforce the channel mode as well. In that case the ID
227 includes the ID of the server. The code now enforces the
228 mode change if the router have different mode than the server.
230 * The notify client operation with CMODE_CHANGE notify can now
231 return NULL client_entry pointer if the CMODE was not changed
232 by client. Application must check for this.
234 * Added <Server ID> argument to INFO command to support server
235 info fetching by Server ID.
237 * Added silc_server_announce_get_channel_users to get assembled
238 packets of channel users of the specified channel. Affected
239 file silcd/server.[ch].
241 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
242 was freed underneath the ID Cache.
244 * Re-announce clients when the server received CHANNEL_CHANGE
245 notify from the router. Affected file silcd/packet_send.c.
247 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
250 crashed since it did not handle the fact that there is no cipher
251 called "3" and didn't check the error condition. Now fixed.
253 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
254 flag. It can be used to send message requests.
256 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Implemented the RESTART command in the client.
260 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
261 notice type messages. Added notice printing to the user
264 * The channel keys are not re-generated if the channel's mode
265 is PRIVKEY, ie private key on the channel exists. Affected
266 files silcd/server.c and silcd/command.c.
268 * Fixed a little bug in channel message delivery when channel
269 private keys are set in the server. Affected file is
272 * Changed the setting on channel->on_channel = TRUE from the
273 silc_client_save_channel_key to the JOIN command reply. The
274 key payload is not received if the private channel key is set.
275 Affected file lib/silcclient/command_reply.c and the
276 lib/silcclient/client_channel.c.
278 * When the CMODE_CHANGE notify is sent and the channel private
279 key mode is removed the channel key must be re-generated in
280 other cells as well. Added this support for the router in the
281 silcd/packet_receive.c.
283 * Added new local command NOTICE to send notice message on
284 channel. Affected file silc/local_command.[ch].
286 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Added new local command ME to the client. It is used to send
289 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
290 some action. Affected file silc/local_command.[ch].
292 * Changed channel_message and private_message client operations
293 to deliver the message flags to the application. Added also
294 the `flags' arguments to the silc_client_send_channel_message
295 and silc_client_send_private_message functions. Affected file
298 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Redefined the Private Message Payload to support private message
301 keys and to support the new private message flags. Updated
302 the protocol specs. Flags makes it possible to have for example
305 * Added new type SilcPrivateMessagePayload and defined an API
306 for it in the lib/silcclient/silcprivate.[ch].
308 * Tested private message private keys successfully. Tested the
309 private message key set, unset and list commands with the new
312 * Redefined the Channel Message Payload to include the channel
313 message flags (equal with private message flags) to support
314 for example CTCP style messages.
316 * Defined some of the message (for channel and private message)
317 flags. Updated the protocol specs and added the flags to the
318 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
320 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Added SilcKeyAgreementStatus type to the key agreement routines
323 to indicate the current status and error if one occured.
324 The status types are defined in the lib/silcclient/silcapi.h.
326 * Added new local command KEY that is used to set and unset private
327 keys for channels, set and unset private keys for private messages
328 with remote clients and to send key agreement requests and
329 negotiate the key agreement protocol with remote client. The
330 key agreement is supported only to negotiate private message keys,
331 it currently cannot be used to negotiate private keys for channels,
332 as it is not convenient for that purpose.
334 * Fixed a minor pending callback setting bug in the function
335 silc_client_get_client_by_id_resolve, now the function works.
336 Affected file lib/silcclient/idlist.c.
338 * Added function silc_net_get_local_port to get local bound
339 port by socket. Added to lib/silcutil/silcnet.[ch].
341 * Added `sockets' and `sockets_count' fields to the SilcClient
342 object. They hold the sockets of the listenning sockets in
343 the client. Listenning sockets may be for example the key
344 agreement server. Affected file lib/silcclient/client.[ch].
345 Added functions the silc_client_add_socket and the
346 silc_client_del_socket. They are exported to the application
349 * Added ~./silc/clientkeys to support other client's public keys.
351 * Renamed verify_server_key client operation to verify_public_key
352 and added one argument to indicate the type of the connection
353 (server, client etc.).
355 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Added silc_server_connection_auth_request to handle the
358 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
359 silcd/packet_receive.[ch].
361 * Added silc_server_send_connection_auth_request into the
362 silcd/packet_send.c to send the connection auth request packet.
364 * Cleaned up the silcd/protocol.c a bit and fixed some memory
367 * Fixed the public key authentication in responder side in the
368 server. The `auth_data' pointer includes the SilcPublicKey
369 not the path to the public key. Affected file silcd/protocol.c.
371 * Implemented the public key authentication in the initiator side
372 in the server. Affected file silcd/protocol.c.
374 * Removed the [RedirectClient] config section from the server
375 configuration. Is not needed and I don't want to implement it.
377 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
379 * Cleaned up the CMODE command in the server. It now works
380 correctly and supports all the modes defined in the protocol.
381 Affected file is silcd/command.c.
383 * Added `hmac_name' field to the SilcChannelEntry in the server
384 to hold the default HMAC of the channel. It can be set when
385 creating the channel (with JOIN command). Affected files
388 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
389 type to indicate the change of the current cipher and hmac
390 on the channel. Client can safely ignore the <cipher> argument
391 (if it chooses to do so) since the CHANNEL_KEY packet will
392 force the channel key change anyway. The <hmac> argument is
393 important since the client is responsible of setting the new
394 HMAC and the hmac key into use.
396 * Fixed the CMODE command in the client library as well.
398 * Tested CMODE command in router environment successfully.
400 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Show the version of the remote client (or server) when connecting
403 to the server. It is logged to the log file. Affected file
406 * Fixed the KILLED notify handling in the client library. The
407 client must be removed from all channels when receiving the
410 Also, do not remove the client entry when giving the KILL
411 command but when the KILLED notify is received.
413 * Removed silc_idlist_find_client_by_nickname from the server.
414 Not needed anymore. Affected files silcd/idlist.[ch].
416 * Implemented the CHANNEL_CHANGE notify type handling to the
417 server. Affected file silcd/server.c.
421 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added silc_server_send_notify_invite to send the INVITE
424 notify between routers.
426 * Implemented the INVITE command correctly to the server.
428 * Implemented the INVITE notify type handling in the server.
430 * Implemented the INVITE command to the client library and on the
433 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Added function silc_server_get_client_resolve to find the
436 client entry by ID from all ID lists and then resolve it
437 (using WHOIS) if it cannot be found. Affected file is
440 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Implemented the BAN command to the client library.
444 * The JOIN command in the server now checks the invite list
447 * Changed the silc_command_reply_payload_encode_va and the
448 silc_command_payload_encode_va to support that if argument is
449 NULL it ignores and checks the next argument. Affected file
450 lib/silccore/silccommand.c.
452 * Added silc_server_send_notify_ban to send the BAN notify
453 type between routers.
455 * Chaned the silc_notify_payload_encode to support that if
456 argument is NULL it ignores and checks the next argument.
457 Affected file lib/silccore/silcnotify.c.
459 * Tested ban lists in router environment successfully.
461 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Implemented BAN command to the server, in silcd/command.[ch].
465 * Removed the BAN and INVITE_LIST modes from the CMODE command
468 * Added function silc_string_match to regex match two strings.
469 Affected files lib/silcutil/silcutil.[ch].
471 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Redefined parts of the SilcChannelEntry in the server to support
474 the new ban and invite lists.
476 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Redefined the INVITE command. The same command can be used to
479 invite individuals to the channel but also to manage the invite
480 list of the channel (to add to and remove from the invite list).
481 Updated the protocol specs.
483 * Added new command SILC_COMMAND_BAN that can be used to manage
484 the ban list of the channel. Updated the protocol specs.
486 * Removed the channel modes: the SILC_CMODE_BAN and the
487 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
488 in the CMODE command. The equivalent features are now available
489 using INVITE and BAN commands. Updated the protocol specs.
491 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
492 in the network about change in the current ban list. The notify
493 type is not used by the client.
495 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
496 support the invite lists.
498 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Added new function silc_string_regexify that converts string
501 including wildcard characters into regex string that can
502 be used by the GNU regex library. Added into the file
503 lib/silcutil/silcutil.[ch].
505 Added silc_string_regex_combine to combine to regex strings
506 into one so that they can be used as one regex string by
507 the GNU regex library. Added into the file
508 lib/silcutil/silcutil.[ch].
510 Added silc_string_regex_match to match two strings. It returns
511 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].

515 * Imported GNU regex to the soruce tree into lib/contrib.
516 Fixed some compiler warning from the regex.c.
518 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Fixed MOTD command in the server to work in router environment.
522 * Fixed the MOTD command in the client library to support
523 the server argument in the command.
525 * Added `nickname_len' argument to the silc_idlist_add_client
526 in the server, as the `nickname' argument may be binary data
529 * Added silc_idlist_get_channels to return all channels from
532 * Implemented LIST command to the server. Affected file is
535 * Implemented the LIST command to the client library and on the
538 * Added [<user count>] argument to the LIST command reply.
539 With private channels the user count is not shown.
541 * Updated TODO and README.
543 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * The client entry's data.registered must be TRUE even with
546 global client entry on global client list. The data.registered
547 is used to check whether the client is anymore in the network,
548 for example with WHOWAS command so it must be valid.
550 * Fixed the WHOWAS command in the server. It now actually works
551 in router environment. Added function into silcd/command_reply.c
552 silc_server_command_reply_whowas_save.
554 * Added silc_idlist_purge function to the silcd/idlist.c
555 to periodically purge the ID Cache.
557 * Fixed INFO command in the server. It works now in router
558 environment. Added <server name> argument to the INFO command
559 reply. Updated the protocol specs.
561 * Fixed minor bug in silc_idcache_purge to not purge if the
562 expire value is zero.
564 * Fixed various bugs in WHOIS and IDENTIFY command handling as
565 they were buggy because of the WHOWAS information.
567 * Fixed local command MSG to handle the async resolving of
568 the remote client properly. It used to fail the first MSG.
569 Affected file silc/local_command.c.
571 * Added `data_len' field to SilcIDCache context.
573 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Update TODO. Todo in commands in the server.
577 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
580 used by routers as broadcast packet to inform other routers
581 about the changed user mode.

584 silcd/packet_receive.c. Added the function
585 silc_server_send_notify_umode to the silcd/packet_send.[ch].
587 * Added new generic Channel Payload and deprecated the New Channel
588 Payload. The New Channel Payload is now the generic Channel
591 * Added new argument `mode' to the silc_server_send_new_channel
592 as it is required in the Channel Payload now.
594 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
595 and created a new and real SilChannelPayload to represent the
596 new generic Channel Payload. Implemented the encode/decode
597 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
599 * Added silc_server_get_client_channel_list to return the list
600 of channels the client has joined for WHOIS command reply.
601 Affected file silcd/server.[ch].
603 * Implemented the channel list sending in the WHOIS command reply
604 in server and in the client.
606 Implemented the channel list displaying on the user interface
607 as well. Affected file silc/client_ops.c.
609 * Added silc_channel_payload_parse_list to parse list of Channel
610 Payloads. It returns SilcDList list of SilcChannelPayloads.
611 Client for example can use this function to parse the list of
612 channels it receives in the WHOIS command reply. The caller
613 must free the list by calling silc_channel_payload_list_free.
614 Affected files lib/silccore/silcchannel.[ch].
616 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Added one new argument <user mode> to the WHOIS command reply
619 to return the mode of the user in SILC. Updated the protocol
622 Implemented it to the server and client.
624 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Fixed the mode printing on the user interface on joining.
627 Affected file silc/client_ops.c.
629 * Implemented the UMODE command and user modes in general to the
630 client library and to the user interface.
632 * Implemented the UMODE command to the server.
634 * The server now sends UNKNOWN_COMMAND error status if client sends
635 unknown command. Affected file silcd/command.c.
637 * All server commands now handle the command identifier the right
638 way when sending the command reply to the client. The client can
639 use to identify the command replies with the identifier.
641 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Added silc_server_get_client_route to resolve the route to
644 the client indicated by the client ID. Affected file is
647 * Added silc_server_relay_packet as general function to relay
648 packet to arbitrary destination. This deprecates functions
649 like _send_private_message_key, _relay_notify etc. Affected
650 file is silcd/packet_send.[ch].
652 Removed silc_server_send_key_agreement,
653 silc_server_send_private_message_key and
654 silc_server_packet_relay_notify functions from the file
655 silcd/packet_send.[ch].
659 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
660 server. Affected file silcd/packet_receive.[ch].
662 * Implemented the KILL command to the client. Implemented the
663 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
664 Affected files lib/silcclient/command[_reply].c and
665 lib/silcclient/client_notify.c. Implemented the KILL notify
666 printing in the user inteface.
668 * Fixed a lot silc_parse_nick memory leaks from the client
669 library in the file lib/silcclient/command.c.
671 * Changed the silc_server_send_notify_on_channels's `sender'
672 argument from SilcSocketConnection to SilcClientEntry to
673 check the sender as entry and not as connection object and not
674 to send to the client provided as argument. The affected file
675 is silcd/packet_send.[ch].
677 * The notify packets that are destined directly to the client used
678 to not to be processed by the server. Now changed that and the
679 server processes all notify packets. After relaying the packet
680 to the client the notify packet is processed in the server.
682 * The silc_server_free_client_data now checks whether there is
683 pending outgoing traffic for the client and purges the data to
684 the network before removing the client entry.
686 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
689 an client is killed from the SILC Network. Updated the protocol
692 Added new function silc_server_send_notify_killed to the
693 silcd/packet_send.[ch].
695 * Added function silc_server_packet_relay_notify to relay notify
696 packets that are destined directly to a client. In this case
697 the server does not process the notify packets but merely relays
698 it to the client. Affected file silcd/packet_send.[ch].
700 Added also silc_server_packet_process_relay_notify to check
701 whereto relay the notify. Affected file is
702 silcd/packet_receive.[ch].
704 * Implemented the KILL command to the server.
708 * Added the backup schema desgined last fall to the protocol
709 specs for everyone to see. The specification is in the
710 *-spec-xx.txt draft and the packet type definitions for the
711 backup routers is in *-pp-xx.txt draft. Thusly, added also
712 new packet type SILC_PACKET_CELL_ROUTERS.
714 * A big security problem in the implementation discovered. The
715 signoff of an client did not cause new channel key generation
716 which it of course should've done. The channel keys must be
717 always re-generated when client leaves (or signoffs) the channel.
718 The silc_server_remove_from_channels funtion now handles
719 the channel key re-generation.
721 * Added `sender' argument to the silc_server_send_notify_on_channels
722 to not to send the client provided as argument. Affected file
723 silcd/packet_send.[ch].
725 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Implemented OPER and SILCOPER commands into the server and
730 * Added silc_auth_verify and silc_auth_verify_data to verify
731 the authentication directly from the authentication payload.
732 It supports verifying both passphrase and public key based
733 authentication. Affected file lib/silccore/silcauth.[ch].
735 * Added `hash' field to the SilcIDListData structure. It is the
736 hash negotiated in the SKE protocol. Affected file is
739 * Slight redesigning of the SilcAuthPayload handling routines.
740 Do not send SilcPKCS but SilcPublicKey as argument.
742 * Implemented the public key authentication support to the
743 serverconfig. The public key is loaded from the provided path
744 and saved as authentication data to void * pointer. Thus,
745 changed the unsigned char *auth_data to void *auth_data;
747 * Fixed SHUTDOWN command to send the reply before the server
748 is shutdown. :) Affected file silcd/command.c.
750 * Fixed fatal bug in CONNECT command. The hostname was invalid
751 memory and server crashed. Affected file silcd/command.c.
753 * Fixed fatal bug in CLOSE command. The server_entry became
754 invalid but was referenced later in the command. Affected file
757 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Fixed fatal bug in failure packet handling. Server ignored
760 the failure and thus crashed when it came.
764 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
767 that the command may be executed only once in (about) 2 seconds.
768 The old SILC_CF_LAG flag is same but allows command bursts up
769 to five before limiting.
771 Added the support for CF_LAG and CF_LAG_STRICT flags to the
772 server code. Various commands now includes the CF_LAG_STRICT
773 flag to disallow any kind of miss-use of the command.
775 * Fixed the silc_buffer_unformat to not to allocate any data
776 if the length of the data is zero. It used to allocate the
777 length + 1. Affected file lib/silcutil/silcbuffmt.c.
779 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Changed the format of AdminConnection configuration section
782 in the server. Added username of the admin to the format.
783 Affected files silcd/serverconfig.[ch].
785 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
786 to return admin configuration data by host, username and/or
789 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Implemented WHOWAS command to the server. Added the functions:
793 silc_server_command_whowas_parse,
794 silc_server_command_whowas_send_reply,
795 silc_server_command_whowas_from_client and
796 silc_server_command_whowas_from_server
798 * Added <Client ID> argument to the WHOWAS command reply. Updated
799 the protocol specs accordingly.
801 * Implemented WHOWAS command and command_reply to the client
804 Implemented the WHOWAS printing on the user interface.
806 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
808 * Added new argument to the WHOWAS command reply, the real name.
809 It is an optional argument. Updated the protocol specs.
811 * Added SilcIDCacheDestructor callback that is registered when
812 the SilcIDCache is allocated. The callback is called when
813 an cache entry in the ID Cache expires, or is purged from the
814 cache. Added into lib/silccore/idcache.[ch].
816 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
817 to destruct the client entries when the cache entry expires.
818 Other ID Cache's in server and in the client library ignores
821 * If the ID Cache entry's `expire' field is zero then the entry
822 never expires. Added boolean `expire' argument to the
823 silc_idcache_add function in the lib/silccore/idcache.[ch].
824 If it is TRUE the default expiry value is used.
826 * Added silc_server_free_client_data_timeout that is registered
827 when client disconnects. By default for 5 minutes we preserve
828 the client entry for history - for WHOWAS command.
830 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Added support to the server to enforce that commands are not
833 executed more than once in 2 seconds. If server receives
834 commands from client more frequently, timeout is registered
835 to process the commands. Affected file silcd/command.c.
836 Added new function silc_server_command_process_timeout.
838 * Changed NICK_NOTIFY handling in client library to check that
839 if the client's nickname was changed, so there is no need to
840 resolve anything from the server.
842 * Removed error printing from the WHOIS and IDENTIFY commands.
843 If error occurs then it is ignored silently in the client library.
844 The application, however, may map the received error to
845 human readable error string. The application currently maps
846 the NO_SUCH_NICKNAME error to string.
848 * Made the command status message public to the application. Moved
849 them from lib/silcclient/command_reply.c to
850 lib/silcclient/command_reply.h. The application can map the
851 received command status to the string with the
852 silc_client_command_status_message function.
854 * Added check to the server to check that client's ID is same
855 as the Source ID in the packet the client sent. They must
858 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Added dist-bzip hook to the Makefile.am to make bzip2
861 compressed distributions.
863 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Server now enforces the maximum length for the nickname and
866 the channel as protocol specification dictates. 128 bytes for
867 nickname and 256 bytes for channel name.
869 * Moved the WHOIS printing to the application. The client libary
870 does not print out the WHOIS information anymore, the application
871 must do it. Renamed silc_client_command_reply_whois_print to
872 the silc_client_command_reply_whois_save.
874 The client's idle time is also sent to the application now, and
875 the idle is shown on screen.
877 * Added silc_client_command_reply_identify_save to save the
878 received IDENTIFY entries.
880 * Do not check for channel private keys in message sending and
881 reception if the channel does not have the PRIVKEY mode set.
882 Affected file lib/silclient/client_channel.c.
884 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
887 just surfaced after chaning the JOIN procedure.
889 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Added silc_client_get_clients_by_list to get client entries
892 from Client ID list, that is returned for example by JOIN
893 and USERS command replies. The application should use this
894 function for example when JOIN command reply is received to
895 resolve the clients already on the channel (library does not
896 do that anymore as USERS command reply is not used in the JOIN
897 procedure anymore). Affected files lib/silcclient/silcapi.h and
898 lib/silcclient/idlist.c.
900 * JOIN command reply and USERS command reply returns now SilcBuffer
901 pointers instead of unsigned char pointers when returning
902 the client list and mode list.
904 * Added <Client ID> argument to the JOIN command reply, mainly
905 for the server to identify for which client the command was
906 originally sent. Updated protocol specs accordingly.
908 * Added SilcDlist private_key pointer to the SilcChannelEntry
909 in the client to support the channel private keys. Affected
910 file is lib/silcclient/idlist.h.
912 * Added SilcChannelPrivateKey argument to the function
913 silc_client_send_channel_message so that application can choose
914 to use specific private ke if it wants to. If it is not provided,
915 the normal channel key is used, unless private keys are set.
916 In this case the first (key that was added first) is used
917 as the encryption key.
919 * Implemented the support for channel private key handling.
920 Implemented the following functions:
922 silc_client_add_channel_private_key,
923 silc_client_del_channel_private_keys,
924 silc_client_del_channel_private_key,
925 silc_client_list_channel_private_keys and
926 silc_client_free_channel_private_keys
928 Affected file lib/silcclient/client_channel.c.
930 * Added the support for the private keys in the channel message
931 sending and encryption and in the message reception and
932 decryption. Affected funtions are
933 silc_client_send_channel_message and silc_client_channel_message.
935 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Added SKE's key verify callback to the client library's
938 KE protocol context. Affected files lib/silcclient/protocol.[ch].
940 * Removed the statement that server (or router) must send USERS
941 command reply when joining to the channel so that the client
942 knows who are on the channel. Instead, the client list and
943 client's mode list is now sent in the JOIN command reply to the
944 client who joined channel. This is better solution.
946 * Added function silc_server_get_users_on_channel and function
947 silc_server_save_users_on_channel to the silcd/server.[ch].
949 * Removed function silc_server_command_send_users from the
952 * Do not show topic on the client library anymore. The topic is
953 sent in the command reply notify to the application and the
954 application must show the topic now.
956 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Added client searching by nickname hash into the IDENTIFY and
959 WHOIS commands in the server as they were clearly missing from
960 them. Affected file is silcd/command.c.
962 * Fixed a bug in private message receiving in the client library.
963 The remote ID was freed and it wasn't supposed, now it is
966 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Minor fix to the channel payload; allocate the data area, as it
969 needs to be of specific length.
971 * If the key agreement port is zero then the operating
972 system will define the bound port. Affected files are
973 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
975 * Added new function silc_channel_payload_decrypt into the file
976 lib/silccore/silcchannel.[ch].
978 * Moved the channel message etc, check from silc_packet_decrypt
979 to applications. The library calls now a generic
980 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
981 when the packet is either normal or special. This was done to
982 allow more wide range of checking that was not allowed when
983 the code was in library. Now applications can do virtually any
984 checks to the packet and return to the library the decision how
985 the packet should be processed. Affected files are
986 lib/silccore/silcpacket.[ch].
988 Added silc_server_packet_decrypt_check to the server and
989 silc_client_packet_decrypt_check to the client library.
991 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
992 to send with specified source and destination information.
994 * Channel message delivery between routers was broken after the
995 channel key distribution was fixed earlier. The channel key
996 was used be to distributed to other routers as well which is not
997 allowed by the protocol. Now this is fixed and channel keys
998 really are cell specific and the channel message delivery between
999 routers comply with the protocol specification.
1001 * Fixed various commands in server to check also the global list
1002 for the channel entry and not just the local list. The affected
1003 file silcd/command.c.
1005 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Added assert()s to buffer formatting and unformatting routines
1008 to assert (if --enable-debug) when error occurs. Affected
1009 file: lib/silcutil/silcbuffmt.c.
1011 * Changed to auto-reconnect to check whether the remote host is
1012 router and register the re-connect timeout if it is. It used
1013 to check that whether we are normal server, but router must do
1014 auto-reconnect with another router as well. Affected file
1017 * Removed the [<key len>] option from CMODE command as the cipher
1018 name decides the key length, nowadays. See the defined ciphers
1019 from the protocol specification.
1021 * Added [<hmac>] option to the CMODE command to define the HMAC
1022 for the channel. Added SILC_CMODE_HMAC channel mode.
1024 * Added [<hmac>] option for the JOIN command so that user can
1025 select which HMAC is used to compute the MACs of the channel
1028 * Added Hmac field to the Channel Message Payload. The integrity
1029 of plaintext channel messages are now protected by computing
1030 MAC of the message and attaching the MAC to the payload. The
1031 MAC is encrypted. Now, it is clear that this causes some
1032 overhead to the size of the packet but rationale for this is that
1033 now the receiver can verify whether the channel message decrypted
1034 correctly and also when private keys are set for the channel the
1035 receiver can decrypt the packet with several keys and check from
1036 the MAC which key decrypted the message correctly.
1038 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1039 lib/silccrypt/silccipher.[ch].
1041 * Added silc_hash_len to return the digest length into the
1042 lib/silcrypt/silchash.[ch].
1044 * Rewrote parts of Silc Channel Payload interface in the
1045 lib/silccore/silcchannel.[ch]. The encode function now also
1046 encrypts the packet and parse function decrypts it.
1048 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Fixed a minor formatting bug in the SKE's key material processing.
1051 It actually might have processed the keys wrong way resulting
1054 * Redefined the mandatory HMAC algorithms and added new algorithms.
1055 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1056 and hmac-md5 truncated to 96 bits. The mandatory is now
1057 hmac-sha1-96. Rest are optional (including the one that used
1058 to be mandatory). Rationale for this is that the truncated HMAC
1059 length is sufficient from security point of view and can actually
1060 make the attack against the HMAC harder. Also, the truncated
1061 HMAC causes less overhead to the packets. See the RFC2104 for
1064 * Added new [hmac] configuration section. The SKE used to use
1065 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1066 is of course wrong. The official names that must be proposed in
1067 the SKE are the ones defined in the protocol specification
1068 (hmac-sha1-96 for example). The user can configure any hmac
1069 using any hash function configured in the [hash] section. At
1070 least, the mandatory must be configured.
1072 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1074 * Added HMAC list to the SKE proposal list. It has now both
1075 hash algorithm list and HMAC list. This makes the protocol
1076 incompatible with previous versions. The SKE now seems to work
1077 the way it is supposed to work, for the first time actually.
1079 * Defined plain Hash algorithms to the protocol specification.
1082 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1084 * Implemented support for key agreement packets into the server.
1085 Added functions silc_server_key_agreement and
1086 silc_server_send_key_agreement. Other than these functions,
1087 server has nothing to do with this packet.
1089 * Added support for private message key packets into the server.
1090 Added functions silc_server_private_message_key and
1091 silc_server_send_private_message_key.
1095 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1096 called in the protocol's final callback instead in the END
1097 protocol state. This makes a little more sense and in the same
1098 time in client we can use the same protocol routines for normal
1099 key exchange and to key agreement packet handling as well.
1101 * Added to both client's and server's KE protocol context the
1102 SilcSKEKeyMaterial pointer to save the key material. We will
1103 bring the key material to the protocol's final callback by doing
1104 this. The final callback must free the key material.
1106 * Added SKE's packet_send callback into client's KE protocol
1107 context so that the caller can choose what packet sending function
1108 is used. This way we can use different packet sending when
1109 doing normal SKE when doing key agreement packet handling (in
1110 the key agreement packet handling we do not want to encrypt
1113 * Implemented the responder side of the key agreement routines
1114 in the client. The client can now bind to specified port and
1115 accept incoming key negotiation. The key material is passed
1116 to the application after the protocol is over.
1118 * Implemented the processing of incoming Key Agreement packet
1119 in the client. Added function silc_client_key_agreement to
1122 * Implemented the intiator side of the key agreement routines
1123 in the client. The client can now initiate key agreement with
1124 another remote client. The key material is passed to the
1125 application after the protocol is over.
1127 * Created client_keyagr.c to include all the key agreement
1130 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1131 SILC_TASK_CALLBACK except that it is not static.
1133 * Created client_notify.c and moved the Notify packet handling
1134 from the client.[ch] into that file.
1136 * Created client_prvmsg.c and moved all private message and
1137 private message key routines from the client.[ch] into that file.
1139 * Create client_channel.c and moved all channel message and
1140 channel private key routines from the client.[ch] into that file.
1142 * Changed silc_client_get_client_by_id_resolve to resolve with
1143 WHOIS command instead of IDENTIFY command, in the file
1144 lib/silclient/idlist.c.
1146 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Implemented the SKE's responder side to the Client library.
1150 * When FAILURE is received to the protocol do not trust it
1151 blindly. Register a timeout to wait whether the remote closes
1152 the connection as it should do it, only after that process the
1153 actual failure. This was changed to both client and server.
1155 * Added client_internal.h to include some of the structures
1156 there instead of client.h in lib/silcclient/.
1158 * Added function silc_task_unregister_by_callback to unregister
1159 timeouts by the callback function.
1161 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Some "Incomplete WHOIS info" errors has been appearing on the
1164 log files. Took away the entry->userinfo check from WHOIS
1165 reply sending. The entry->userinfo is now " " if client did not
1166 provide one. I thought this was fixed earlier but something
1167 is wrong still. Let's see if the error still appears.
1169 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Fixed a minor bug in the login when the channel key is
1172 re-generated in the server. It used to generate the key in
1173 wrong order and thus caused problems in the channel traffic.
1175 * Fixed a minor bug in channel key distsribution after
1176 KICK command. The key was not sent to the router even though
1179 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Added silc_ske_process_key_material_data as generic routine
1182 to process any key material as the SILC protocol dictates. The
1183 function is used by the actual SKE library but can be used by
1184 applications as well. This relates to the private message keys
1185 and the channel private keys since they must be processed the
1186 same way the normal SILC session keys. The protocol dictates
1187 this. Affected files: lib/silcske/silcske.[ch].
1189 Added also silc_ske_free_key_material to free the
1190 SilcSKEKeyMaterial structure.
1192 * Defined silc_cipher_set_key function to set the key for
1193 cipher without using the object's method function. The affected
1194 files: lib/silccrypt/silccipher.[ch].
1196 * Implemented silc silc_client_add_private_message_key,
1197 silc_client_add_private_message_key_ske,
1198 silc_client_del_private_message_key,
1199 silc_client_list_private_message_keys and
1200 silc_client_free_private_message_keys functions in the
1203 Added functions silc_client_send_private_message_key to send
1204 the Private Message Key payload and silc_client_private_message_key
1205 to handle incoming Private Message Key payload.
1207 * Added Cipher field to the Private Message Key payload to set
1208 the cipher to be used. If ignored, the default cipher defined
1209 in the SILC protocol (aes-256-cbc) is used.
1211 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Removed lib/silcclient/ops.h file.
1215 Redefined parts of the SILC Client Library API. Created new
1216 file silcapi.h that deprecates the ops.h file and defines the
1217 published Client Library API. Defined also private message key
1218 API and channel private key API into the file.
1220 This is the file that the application must include from the
1221 SILC Client Library. Other files need not be included by
1222 the application anymore.
1224 * Added new key_agreement client operation callback and also
1225 defined the Key Agreement library API for the application.
1227 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1230 is used by clients to request key negotiation between another
1231 client in the SILC network. If the negotiation is started it
1232 is performed using the SKE protocol. The result of the
1233 negotiation, the secret key material, can be used for example
1234 as private message key.
1236 Implemented the Key Agreement payload into the files
1237 lib/silccore/silauth.[ch].
1239 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Redefined ciphers for the SILC protocol. Added some new ciphers
1242 and defined the key lengths for the algorithms. Changed the
1243 code accordingly. The default key length is now 256 bits.
1245 * Fixed SKE key distribution function silc_ske_process_key_material
1246 when the key length is more than 128 bits. The default key
1247 length in SILC is now 256 bits.
1249 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1250 to indicate unsupported algorithm.
1252 * Renamed rijndael.c to aes.c and all functions as well.
1254 * Fixed a long standing channel key setting bug in client library.
1255 Weird that it has never surfaced before.
1257 * Fixed bug in channel deletion. If the entire channel is removed
1258 then it must also delete the references of the channel entry
1259 from the client's channel list as the client's channel entry and
1260 the channel's client entry share same memory.
1262 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Implemented CONNECT and SHUTDOWN commands in the client.
1266 * Implemented CLOSE command to the client.
1268 * Added the function silc_idlist_find_server_by_name into the
1269 files silcd/idlist.[ch].
1271 Added the function silc_idlist_find_server_by_conn into the
1272 files silcd/idlist.[ch].
1274 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * DIE command was renamed to SHUTDOWN. Updated the both code
1279 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1280 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1282 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1285 * Added function silc_server_create_connection function to create
1286 connection to remote router. My server implementation actually
1287 does not allow router to connect to normal server (it expects
1288 that normal server always initiates the connection to the router)
1289 so the CONNECT command is only good for connecting to another
1292 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1295 or some other client was kicked from the channel.
1297 Implemented the handling of the notify type to both client
1300 Implemented silc_server_send_notify_kicked to send the KICKED
1301 notify. It is used to send it to the server's primary router.
1303 * Implemented the KICK command into server and client.
1305 * Added `query' argument to the silc_idlist_get_client function
1306 to indicate whether to query the client from server or not if
1309 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1310 to indicate that the client is not channel founder.
1314 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Removed the rng context from SilcPacketContext structure and
1317 changed that the packet routine uses the Global RNG API.
1319 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Added support for quit message that client can "leave" on the
1322 channel when it quits the SILC. It is ditributed inside the
1323 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1325 Added silc_server_free_client_data that will take the
1326 signoff message as argument.
1328 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1330 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Updated parts of the protocol specification to keep it up
1335 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1338 payloads in one packet.
1340 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1341 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1342 use now the new List flag.
1344 * Also deprecated the following packet types: REPLACE_ID,
1345 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1347 * Added list support for Notify packet in server.
1349 * Added silc_server_send_notify_channel_change to send the
1350 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1351 the silc_server_send_replace_id.
1353 * Added silc_server_send_notify_nick_change to send the
1354 NICK_CHANGE notify type. Deprecates the function
1355 silc_server_send_replace_id.
1357 * Added silc_server_send_notify_join to send the JOIN notify type.
1358 Deprecates the function silc_server_send_new_channel_user.
1360 * Added silc_server_send_notify_leave to send LEAVE notify type.
1361 Deprecates the function silc_server_send_remove_channel_user.
1363 * Added silc_server_send_notify_cmode and
1364 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1365 types. Deprecates the silc_server_send_set_mode function.
1367 * Added SERVER_SIGNOFF notify type to indicate that server has
1368 quit. This means that all clients on the channel from that
1369 server will drop. This can be also used when netsplit happens.
1371 Deprecated REMOVE_ID packet type since it is not needed anymore
1374 Added silc_server_send_notify_server_signoff to send the
1375 SERVER_SIGNOFF notify type. Deprecates the function
1376 silc_server_send_remove_id.
1378 Added also silc_server_send_notify_signoff to send the
1379 SIGNOFF notify type.
1381 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1382 SILC protocol from this day on. Changed the protocol
1383 specification as well.
1385 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1386 notify type. It is used between routers to notify about
1387 topic changes on a channel.
1389 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1392 * Partly updated the protocol specification to comply with the
1393 changes now made. It is still though a bit outdated.
1395 * The JOIN notify type now takes one extra argument <Channel ID>.
1396 The packet used to be destined to the channel but now the
1397 JOIN type may be sent as list thus it is impossible to
1398 destine it to any specific channel. By adding this argument
1399 it is again possible.
1401 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Added CREDITS file. The CHANGES and CREDITS file will appear
1404 in the distribution as well.
1406 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1408 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1409 types in the server's silcd/packet_receive.c.
1411 * Implemented CMODE and CUMODE to work in router environment.
1413 * Fixed minor encoding and decoding buglet from the
1414 lib/silccore/silcmode.c.
1416 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1419 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1421 * Changed all SilcConfigServer* and silc_config_server* to
1422 SilcServerConfig* and silc_server_config*, respectively.
1425 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1427 * Associated the ID (client or server ID) to the Authentication
1428 Payload to avoid any possibility of forging. Updated the
1429 protocol specification and the code accordingly.
1431 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * The RSA key length is now save to the RsaKey context in the
1434 key generation process in lib/silccrypt/rsa.c. The key length
1435 is now used to figure out the maximum size of the block allowed
1436 to be encrypted/signed.
1438 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1439 is equivalent to the silc_mp_mp2bin but does not allocate any
1442 * Changed silc_mp_mp2bin API to take length argument. If it is
1443 non-zero then the buffer is allocated that large. If zero, then
1444 the size is approximated using silc_mp_sizeinbase, which however
1447 * Created Global RNG API which is global RNG that application can
1448 initialize. After initializing, any routine anywhere in the
1449 code (including library) can use RNG without allocating a new
1450 RNG object. This was done to allow this sort of use of the
1451 RNG in code that has no chance to allocate RNG object. All
1452 applications currently allocate this and many routines in the
1453 library use this. Affected file lib/silccrypt/silcrng.[ch].
1455 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1456 it to use the Global RNG API.
1458 * Defined Authentication Payload into protocol specification that
1459 is used during SILC session to authenticate entities. It is
1460 used for example by client to authenticate itself to the server
1461 to obtain server operator privileges.
1463 Implemented this payload into the lib/silccore/silcauth.[ch].
1464 Implemented also routines for public key based authentication
1465 as the new protocol specification dictates.
1467 Moved definitions of different authentication methods from
1468 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1470 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1471 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1472 silc_pkcs_verify_with_hash functions into the file
1473 lib/silccrypt/silcpkcs.[ch].
1475 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * The client entry's userinfo pointer must be always valid.
1478 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1479 will fail since it requires the userinfo. Now, the userinfo
1480 is allocated as "" if actual userinfo does not exist. Actually,
1481 it must exist and it is totally Ok to drop client connections
1482 that does not announce the userinfo. However, we will make
1483 this workaround for now.
1485 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1486 to return the remote port by socket.
1488 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1491 SILC_SERVER_PENDING_EXEC and added an new macro
1492 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1493 data or when error occurs while processing the pending command.
1495 Added new argument `destructor' into silc_server_command_pending
1496 and to the SilcServerCommandPending object. This destructor is
1497 now called after calling the pending callback or if error occurs
1498 immediately. If error occurs the actual pending callback won't
1499 be called at all - only the destructor. The destructor may be
1500 NULL if destructor is not needed.
1502 All this applies for client library code as well. Similar
1503 changes were made there as well for the pending commands.
1505 In the client, the application must now allocate the
1506 SilcClientCommandContext with the silc_client_command_alloc
1509 * Added reference counter to the SilcServerCommandContext. Added
1510 function silc_server_command_alloc and silc_server_command_dup
1513 Same type of functions added to the client library for the same
1516 * Removed the cmd_ident from IDListData away since it is now
1517 global for all connections. It is the command identifier used
1518 in command sending and with pending commands. The affected file
1521 * Added reference counter to the SilcSocketConnection objecet to
1522 indicate the usage count of the object. The object won't be
1523 freed untill the reference counter hits zero. Currently only
1524 server uses this, and client ignores it. The client must be
1525 set to use this too later. The affected files are
1526 lib/silccore/silcsockconn.[ch]. Added also the function
1527 silc_socket_dup to increase the reference counter.
1529 This was mainly added because it is possible that the socket
1530 is removed underneath of pending command or other async
1531 operation. Now it won't be free'd and proper DISCONNECTING
1532 flags, etc. can be set to avoid sending data to connection that
1533 is not valid anymore.
1535 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1536 the connection. After that it sets SILC_SET_DISCONNECTED.
1537 It is, however, possible that the socket data is not still freed.
1538 The silc_server_packet_process now checks that data is not
1539 read or written to connection that is DISCONNECTED. The socket
1540 get's freed when the reference counter hits zero.
1542 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Changed the client operation API: channel_message operation's
1545 `sender' is now the client entry of the sender, not the nickname
1546 and the `channel' is the channel entry, not the channel name.
1548 In the private_message operation the `sender' is now also the
1549 client entry of the sender not the nickname.
1551 Affected file is lib/silcclient/ops.h and all applications
1552 using the client operations.
1554 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Moved the calling of ops->connect() from connect_to_server_final
1557 into receive_new_id functin since that is the point when the
1558 client is actually allowed to send traffic to network. The
1559 affected file is lib/silcclient/client.c.
1561 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1564 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1565 (if needs broadcasting) instead of broadcasting the packets one
1566 by one which would make a burst in the network traffic.
1568 * Added `broadcast' argument to the functions in silcd/server.[ch]
1569 silc_server_create_new_channel[_with_id] to indicate whether
1570 to send New Channel packet to primary router.
1572 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Added new function into the silcd/server.[ch] files:
1575 silc_server_create_new_channel_with_id to create new channel with
1576 already existing Channel ID.
1578 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1579 lib/silccore/silcpacket.h. This packet is used t send list of
1580 Set Mode payloads inside one packet. Server uses this to set
1581 the modes for the channels and clients on those channels, that it
1582 announced to the router when it connected to it. The protocol
1583 specification has been updated accordingly.
1585 * The silc_server_new_channel did not handle the packet coming
1586 from normal server as it normally does not send that. However,
1587 when it announces its channels it does send it. Implemented
1588 the support for that.
1590 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1591 into the file lib/silccore/id.h.
1593 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Fixed memory leaks in the functions silc_idlist_del_client,
1596 silc_idlist_del_channel and silc_idlist_del_server in the file
1597 silcd/idlist.c. All of those leaked like a sieve.
1599 * Fixed some small memory leaks in the client's function
1600 silc_client_notify_by_server.
1602 * Added functions into silcd/server.c: silc_server_announce_clients,
1603 silc_server_announce_channels and silc_server_announce_server.
1604 These functions are used by normal and router server to announce
1605 to its primary router about clients, channels and servers (when
1606 router) that we own. This is done after we've connected to the
1609 These functions effectively implements the following packet types:
1610 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1611 and SILC_PACKET_NEW_ID_LIST.
1613 * Added new functions into the silcd/packet_receive.[ch]:
1614 silc_server_new_id_list, silc_server_new_channel_list and
1615 silc_server_new_channel_user_list to handle the incoming
1616 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1618 * Added support of changing Channel ID in the function
1619 silc_server_replace_id. If the server that announces a channel
1620 to the router already exists in the router (with same name but
1621 with different Channel ID), router is responsible to send
1622 Replace ID packet to the server and force the server to change
1623 the Channel ID to the one router has.
1625 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1626 client that the Channel ID has been changed by the router. The
1627 normal server sends this to the client. Client must start using
1628 the new Channel ID as the channel's ID.
1630 Implemented handling of this new type into lib/silcclient/client.c
1631 into the function silc_client_notify_by_server.
1633 * Added new function silc_idlist_replace_channel_id into the files
1634 silcd/idlist.[ch] to replace the Channel ID.
1636 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Call silc_server_command_identify_check always when processing
1639 the IDENTIFY command in silcd/command.c
1641 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1644 send keepalive packets. The packet can be sent by clients,
1645 servers and routers.
1647 Added function silc_socket_set_heartbeat into the file
1648 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1649 If not set, the heartbeat is not performed. The actual
1650 heartbeat is implemented in the low level socket connection
1651 library. However, application is responsible of actually
1654 Added silc_server_send_heartbeat to send the actual heartbeat
1655 packet into silcd/packet_send.[ch]. Server now performs
1656 keepalive with all connections.
1658 * Added silc_task_get_first function into lib/silcutil/silctask.c
1659 to return the timeout task with shortest timeout. There was a bug
1660 in task unregistration that caused problems. TODO has been
1661 updated to include that task system must be rewritten.
1663 * The client library will now resolve the client information when
1664 receiving JOIN notify from server for client that we know but
1665 have incomplete information.
1667 * Rewrote parts of silc_server_remove_from_channels and
1668 silc_server_remove_from_one_channel as they did not remove the
1669 channel in some circumstances even though they should've.
1671 * Encryption problem encountered in server:
1673 The LEAVE command used to send the Channel Key packet to the
1674 router immediately after generating it. However, the code
1675 had earlier sent Remove Channel user packet but not immediately,
1676 ie. it was put to queue. The order of packets in the router
1677 was that Channel Key packet was first and Remove Channel User
1678 packet was second, even though they were encrypted in the
1679 reverse order. For this reason, MAC check failed. Now, this
1680 is fixed by not sending the Channel Key packet immediately but
1681 putting it to queue. However, this is more fundamental problem:
1682 packets that are in queue should actually not be encrypted
1683 because packets that are sent immediately gets encrypted
1684 actually with wrong IV (and thus MAC check fails). So, packets
1685 that are in queue should be encrypted when they are sent to
1686 the wire and not when they put to the queue.
1688 However, the problem is that the current system has not been
1689 designed to work that way. Instead, the packet is encrypted
1690 as soon as possible and left to the queue. The queue is then
1691 just purged into wire. There won't be any fixes for this
1692 any time soon. So, the current semantic for packet sending
1695 o If you send packet to remote host and do not force the send
1696 (the packet will be in queue) then all subsequent packets to the
1697 same remote host must also be put to the queue. Only after the
1698 queue has been purged is it safe again to force the packet
1701 o If you send all packets immediately then it safe to send
1702 any of subsequent packets through the queue, however, after
1703 the first packet is put to queue then any subsequent packets
1704 must also be put to the queue.
1706 Follow these rules and everything works fine.
1708 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Added new function silc_server_remove_clients_by_server to
1711 remove all client entries from ID list when the server connection
1712 is lost. In this case it is also important to invalidate all
1713 client entires as they hold the invalid server entry. This
1714 fixes fatal bug when server has lost connection and will reconnect
1717 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Made some sanity checks to silc_server_daemonise like to check
1720 whether the requested user and group actually exists.
1722 * Added sanity check to SKE's silc_ske_responder_finish to check
1723 that the public and private key actually is valid.
1725 * Invalidate the client's nickname when receiving Replace ID
1726 packet and the Client ID is being replaced. This means that the
1727 server will query the nickname if someone needs it (client)
1730 * Sort the ID Cache in client library when the ID Cache data
1731 has changed (needs sorting).
1733 * Do not allow for SILC client to create several connections to
1734 several servers. The client does not support windows right now
1735 and generating multiple connections causes weird behaviour.
1737 Irssi-silc client does support windows and can handle several
1738 connections without problems, see: www.irssi.org and SILC plugin.
1740 * Fixed some places where client was added to the IDList. The
1741 rule of thumb is following (in order to get everything right):
1742 If the client is directly connected local client then the
1743 `connection' argument must be set and `router' argument must be
1744 NULL to silc_idlist_add_client function. If the client is not
1745 directly connected client then the `router' argument must
1746 bet set and the `connection' argument must be NULL to the
1747 silc_idlist_add_client function.
1749 * The funtion silc_server_packet_send_local_channel actually did
1750 not check whether the client was locally connected or not. It
1751 does that now. Fixed a bug related to LEAVE command.
1753 * Fixed Remove Channel User payload parsing bug in server's
1754 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1756 * The server's silc_server_save_channel_key now checks also the
1757 global ID list for the channel as it might not be in the local
1758 list. Fixed a bug related to LEAVE command.
1760 * Is this the end of the [<unknown>] buglet that has been lurking
1761 around for a long time? A little for loop fix in server's
1762 silc_server_command_whois_parse that is used by both IDENTIFY
1763 and WHOIS command. At least, this was a clear bug and a cause
1764 of one type of [<unknown>] buglet.
1766 * WHOIS and IDENTIFY commands call the function
1767 silc_server_command_[whois/identify]_check function even if
1768 we are not router server.
1770 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added --with-gmp configuration option. If set the GMP
1773 is always compiled in the SILC source tree. If not set then
1774 it is checked whether the system has the GMP3 installed. If
1775 it has then the GMP won't be compiled (the system's headers
1776 and library is used), if it doesn't have it then the GMP is
1777 compiled in the SILC source tree.
1779 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Changed RSA private exponent generation to what PKCS #1
1782 suggests. We try to find the smallest possible d by doing
1783 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1784 not security fix but optimization.
1786 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Added new config entry [Identity] to fork the server and run
1789 it as specific user and group. A patch from Bostik.
1791 * Imported Dotconf configuration library into lib/dotconf.
1792 This will be used to create the SILC configuration files later.
1793 It will appear in the distsribution after this commit.
1795 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * A big code auditing weekend happening. Auditing code for
1798 obvious mistakes, bugs and errors. Also, removing any code
1801 Removed files for being obsolete:
1803 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1804 inline in the file lib/silcutil/silcbuffer.h)
1806 o lib/silcutil/silcbufutil.c (the header has inline versions)
1808 Changed code to fix possible error conditions:
1810 o The buffer formatting routines now check that the destination
1811 buffer really has enough space to add the data. This applies for
1812 both buffer formatting and unformatting
1813 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1814 unformatting was changed to accomodate following rules:
1815 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1816 sent to the function while XXX_*STRING will not allocate or copy
1817 the data into the buffer. Instead it sets the pointer from the
1818 buffer into the pointer sent as argument (XXX_*STRING used to
1819 require that the pointer must be allocated already). This change
1820 makes this whole thing a bit more consistent and more optimized
1821 (note that the data returned in the unformatting with XXX_*STRING
1822 must not be freed now). The routines return now -1 on error.
1824 o Tried to find all code that use buffer_format and buffer_unformat
1825 and added return value checking to prevent formatting and
1826 especially unformatting errors and possible subsequent fatal
1829 o Changed ske->x and ske->KEY to mallocated pointers in
1830 lib/silcske/silcske.h. Fixed possible data and memory leak.
1832 o Added return value checking to all *_parse* functions. Fixed
1833 many memory leaks as well.
1835 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1836 so that buffer overflows would not happen. All code now also
1837 checks the return value as it can fail.
1839 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added reconnection support to server if the normal server looses
1842 its connection to the router (for example if router is rebooted).
1843 The server performs normal reconnection strategy implemented
1844 to the server. Affected file silcd/server.c.
1846 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Added new packet type SILC_PACKET_SET_MODE that is used to
1849 distribute the information about changed modes (for clients,
1850 channels and clients channel modes) to all routers in the
1851 network. Updated the protocol specification accordingly.
1853 Added functions into silcd/packet_send.c and
1854 silcd/packet_receive.c: silc_server_send_set_mode,
1855 silc_server_set_mode.
1857 Added new files silcmode.[ch] into lib/silccore that implements
1858 the encoding and decoding of Set Mode Payload. Added new type
1859 SilcSetModePayload. Moved the definitions of different modes
1860 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1862 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Oops, a little mistake in server's connection authentication
1865 protocol. The protocol is not ended with FAILURE but with
1866 SUCCESS if the authentication is Ok. :) Affected file is
1869 * Implemented NICK_CHANGE notify handling in server in the file
1870 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1871 the local clients on the channel. After the changing nickname
1872 in router environment snhould work and the [<unknown>] nickname
1873 should appear no more.
1875 The silc_server_replace_id function that receives the Replace ID
1876 payload now sends the NICK_CHANGE notify type also in the file
1877 silcd/packet_receive.c
1879 * Changed WHOIS and IDENTIFY command to support the maximum amount
1880 of arguments defined in protocol specs (3328 arguments). This
1881 fixed a bug that caused problems when there were more than three
1884 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Added extra parameter, command identifier, to the
1887 silc_client_send_command so that explicit command identifier
1890 Changed that ID list routines uses specific command identifier
1891 when sending WHOIS/IDENTIFY requests to the server so that they
1892 can be identified when the reply comes back.
1894 Affected files lib/silcclient/command.[ch],
1895 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1897 * Added `sender' argument to silc_server_packet_send_to_channel
1898 to indicaet the sender who originally sent the packet to us
1899 that we are now re-sending. Ignored if NULL. Affected file
1900 silcd/packet_send.[ch].
1902 * Added some server statistics support in silcd/server_internal.h
1903 SilcServerStatistics structure and around the server code. Also
1904 send some nice statistics information when client is connecting
1907 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Fixed channel ID decoding in server's JOIN command reply in
1910 silcd/command_reply.c
1912 * Fixed braodcasting of replace ID payload to not to send it if
1913 we are standalone server in silcd/packet_receive.c.
1915 * Fixed all channel message sending routines to not to send
1916 packets to clients that has router set, since they are routed
1917 separately in the same function earlier. Affects file
1918 silcd/packet_send.c and all channel packet sending functions.
1920 * In USERS reply, res_argv[i] are not allocated, the table
1921 is allocated. Thus changed that free the table, not its
1924 * In server's whois_check and identify_check if the client is
1925 locally connected do not send any WHOIS commands - they are not
1928 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Fixed some minor bugs in client when sending WHOIS command. The
1931 arguments was in wrong order.
1933 * Removed statis function add_to_channel from server in
1934 silcd/command.c that was previously used with the joining but
1937 * Tested USERS command in router environment successfully with two
1938 routers, two servers and two clients.
1940 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Reorganized the USERS command and command reply in client library
1943 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1944 When the command is given by user we register a pending command
1945 callback that will reprocess the command after the reply has been
1946 received from the server. When reprocessing the packet we then
1947 display the information. Thus, the USERS information is displayed
1948 now in the command callback instead of in the command reply
1949 callback. The processing of the command is same as previously
1950 when server has sent the command reply in the JOINing process.
1952 * Added to USERS command in silcd/command_reply.c to join the client,
1953 we didn't use to know about, to the channel after we've created
1954 a client entry for it. Also, for clienet we did know already still
1955 check whether it is on the channel or not and add it if not.
1957 * Removed silc_server_command_join_notify as the function and its
1960 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Changed the client's pending command handling to the same as the
1963 server's pending command handling. It is also now possible to
1964 execute command reply functions from other command reply
1965 function as the function callbacks for commands and command
1966 replies are one and same. The pending commands are not static
1967 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1968 in client connection context. Thus, pending commands are server
1969 connection specific as it is convenient.
1971 Changed the function silc_client_command_pending and
1972 silc_client_command_pending_del and added new function
1973 silc_client_command_pending_check. Removed the
1974 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1977 * Added cmd_ident, current command identifier, to the client
1978 connection context in lib/silcclient/client.h to keep track on
1979 command identifiers used in command sending. Client's command reply
1980 function handling now supports the mandatory command identifiers.
1982 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1983 funtions in client to fully support pending command callbacks.
1985 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1986 as one of the arguments to the application in the command reply
1989 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1990 before first releasing SILC but came back. Now it is removed again
1991 and should come back nomore. The FORWARDED flag was used only
1992 by the JOINing procedure by forwarding the command packet to router.
1993 Now, the JOINing procedure has been changed to more generic (due
1994 to various router environment issues) and FORWARDED is not needed
1995 anymore for anything. The protocol specification is yet to be
1998 Now, removed silc_server_packet_forward from server and the flag
1999 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2001 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Renamed NAMES command to USERS command. The NAMES was named that
2004 due to historical reasons. Now it is renamed. Also, rewrote
2005 parts of the USERS command. The nickname list is not sent anymore
2006 by the server. Only Client ID and mode lists are sent in the USERS
2007 command. Changed this also to the protocol specification.
2009 The client now resolves the names and stuff after it receives
2010 the USERS list from the server when joining to the channel.
2012 * WHOIS and IDENTIFY commands has been changed to support multiple
2013 Client ID's per command. One can now search for multiple users
2014 in the network by sending only one WHOIS or IDENTIFY command.
2015 Changed the code and the protocol specifications.
2017 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2018 uses silc_server_command_whois_parse to parse the request. */
2020 * If normal server, do not parse the WHOIS and IDENTIFY requests
2021 before sending it to the router. Saves some time.
2023 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Fixed JOIN command on client library. Wrong number of arguments
2026 used to crash the client.
2028 * Added silc_server_channel_has_global function to check whether
2029 channel has global users or not.
2031 * Added silc_server_channel_has_local function to check whether channel
2032 has locally connected clients on the channel.
2034 * The silc_server_remove_from_one_channel now checks whether the
2035 channel has global users or not after given client was removed from
2036 the channel. It also checks whether the channel has local clients
2037 on the channel anymore. If it does not have then the channel entry
2038 is removed as it is not needed anymore.
2040 * The silc_server_notify now checks on JOIN notify whether the joining
2041 client is one of locally connected or global. If it is global then
2042 the channel has now global users on the channel and that is marked
2043 to the channel entry. Also, it now saves the global client to
2044 global list who is joining and JOINs it to the channel. This is
2045 for normal server, that is.
2047 Changed silc_server_send_notify_on_channel,
2048 silc_server_packet_relay_to_channel and
2049 silc_server_packet_send_to_channel check if we are normal server
2050 and client has router set (ie. global client) do not send the
2051 message to that client, as it is already routed to our router.
2053 * Implemented LEAVE notify type handling in silc_server_notify
2056 * Tested LEAVE command in router environment successfully. Tested
2057 with two routers, two servers and two clients.
2061 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2063 * Implemented SIGNOFF notify type handling in silc_server_notify
2066 * silc_server_remove_id now removes the client entry from all channels
2067 it has joined and thusly sends SIGNOFF notify type.
2069 * Rewrote the NAMES list generation in server by removing two excess
2070 loops. The lists are created now inside one loop.
2072 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * silc_server_remove_channel_user checks now also global list
2075 for channel and client.
2077 * silc_server_new_channel_user checks now both local and global
2078 list for channel and client. Fixed a bug in client id decoding.
2079 Used to decode wrong buffer.
2081 * silc_server_channel_message checks now both local and global
2082 list for channel entry.
2084 * Tested channel joining (hence JOIN) in router environment
2085 successfully. Tested with two routers, two servers and two
2088 * Tested channel message sending in router environment successfully.
2090 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added silc_server_save_channel_key into server.[ch] to save the
2093 received channel key in Channel Key payload processing. It is
2094 also used in JOIN command reply handling.
2096 Equivalent function silc_client_save_channel_key added into
2097 client.[ch] into client library.
2099 * Changed JOIN command reply to send information whether the channel
2100 was created or not (is existing already) and the channel key
2101 payload. Changed protocol specs accordingly.
2103 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2104 the request was sent by ID and not by nickname. Crashed on
2107 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2110 now correctly save the received data.
2112 * silc_server_free_sock_user_data now notifies routers in the
2113 network about entities leaving the network.
2115 At the same time implemented functions silc_server_remove_id
2116 and silc_server_send_remove_id to receive and send REMOVE_ID
2117 packets. The packet is used to notify routers in the network
2118 about leaving entities. The ID removed will become invalid in
2121 * Added function silc_idlist_del_server into server. Removes and
2122 free's server entry from ID list.
2124 * silc_server_private_message function now checks, if we are router,
2125 that the destination ID really is valid ID, naturally.
2127 * In router when NEW_ID packet is received (for new client) the
2128 hash of the Client ID is saved in the ID Cache but the
2129 client->nickname is set to NULL, instead of putting the hash
2132 IDENTIFY command now also checks that client->nickname must be
2133 valid. If it is not if will request the data from the server who
2134 owns the client. Added new function
2135 silc_server_command_identify_check.
2137 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2138 to set the command to already allocated Command Payload.
2140 * Tested private message sending in router environment with two
2141 routers, two servers and two clients. Fixed minor bugs and now
2144 * Fixed segfault from client's NAMES command. Used to crash if
2147 * Forwarded packets must not be routed even if it is not destined
2148 to the receiver. Changed server code comply with this.
2150 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Added `require_reverse_mapping' boolean value to ServerParams
2153 structure. If TRUE (not default) the server will require that
2154 the connecting host has fully qualified domain name.
2156 If the reverse mapping is not required and hostname could not be
2157 found the IP address is used as hostname.
2159 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Implemented version string checking to both client and server.
2162 The check is incomplete currently due to the abnormal version
2163 strings used in development version of SILC.
2165 * Changed all command functions in server to use the new
2168 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Changed char *data to unsigned char *data in ID Cache system to
2171 support binary data as ID Cache data. Changed code to support
2172 binary data in lib/silccore/idcache.c.
2174 * Renamed silc_server_packet_relay_command_reply to
2175 silc_server_command_reply as it is normal packet receiving
2176 function. Rewrote the function to accept command replys for
2177 servers and not only for clients.
2179 * Mark remote router always as registered server if we are connecting
2180 to it. Otherwise, commands sent by the router to us are ignored.
2182 * All ID List find routines now returns the ID Cache Entry pointer
2183 as well if requested.
2185 * WHOIS command works now in router environment, tested with two
2186 routers, two servers and two clients.
2188 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2189 in router environment (as it is almost equivalent to WHOIS) but
2190 hasn't been tested thoroughly. Added new functions:
2192 silc_server_command_identify_parse
2193 silc_server_command_identify_send_reply
2194 silc_server_command_identify_from_client
2195 silc_server_command_identify_from_server
2197 * Disabled route cache adding because adding two different ID's with
2198 same IP replaces the old cache entry thus giving wrong route.
2199 The entry->router->connection is always the fastest route anyway
2200 so route cache may not be needed. Of course, new routes maybe
2201 established after receiving the ID when the entry->router->connection
2202 might not be anymore the most optimal.
2204 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Add route cache for received ID for fast routing.
2208 * Added silc_server_packet_route to route received packet on router
2209 that is not destined to us.
2211 * Renamed silc_server_get_route to silc_server_route_get.
2213 * Added id_string and id_string_len fields into SilcServer to
2214 include encoded ServerID for fast comparing without excess
2215 encoding of the ID's.
2217 * Cleaned up WHOIS command on server side. Added following static
2220 silc_server_command_whois_parse
2221 silc_server_command_whois_check
2222 silc_server_command_whois_send_reply
2223 silc_server_command_whois_from_client
2224 silc_server_command_whois_from_server
2226 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2227 arguments in command replies. All command functions should be
2228 updated to use this macro.
2230 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Minor typo fixes on command reply handling on server.
2234 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Added silc_server_command_add_to_channel internal routine to add
2237 the client to the channel after router has created the channel and
2238 sent command reply to the server.
2240 * Added generic silc_server_send_command to send any command from
2243 * Use static buffer with ID rendering instead of duplicating data.
2245 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Fixed a channel user mode bug when joining to a channel server gave
2248 everybody channel founder rights, oops.
2250 * We mark ourselves as the router of the incoming server connection
2251 if we are router ourselves. This way we can check in some packet
2252 sending functions whether it is locally connected server. For
2253 incoming router connections we put NULL.
2255 * For router sending packets locally means now always sending the
2256 packet cell wide; to local clients and local servers. For normal
2257 server sending packet locally means sending it to only local
2260 * Fixed the JOIN command to really work in router environment. If the
2261 channel is created it is always created by the router. Router is
2262 also responsible of making the initial joining to the channel,
2263 sending JOIN notify to the sending server and distributing
2264 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2265 does not exist server doesn't do anything else but forward the
2266 command to the router which performs everything.
2268 * Added silc_server_send_channel_key function to send the Channel Key
2271 * Added silc_server_create_channel_key to create new channel key. The
2272 channel key is now re-generated everytime someone joins or leaves
2273 a channel, as protocol dictates. Note: channel->key_len is the
2276 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2279 packet_receive.[ch] to separate packet sending and receiving
2280 routines. The server.[ch] now includes everything else including
2281 actual packet processing (writing and reading data) and other
2284 Renamed silc_server_private_message_send_internal to
2285 silc_server_send_private_message. The routine is still though
2286 used only to relay private messages as server does not send
2287 private messages itself.
2289 Renamed silc_server_new_channel to silc_server_create_new_channel
2290 and added new function sicl_server_new_channel that handles the
2291 incoming New Channel packet. Added also new sending function
2292 silc_server_send_new_channel to send New Channel Payload.
2294 * Added new function silc_server_notify to process incoming notify
2295 packet to the server/router. Server may then relay the notify
2296 to clients if needed.
2298 * Added new function silc_server_new_channel_user to process incoming
2299 New Channel User packet. Router will redistribute the packet and
2300 send JOIN notify to its local clients and locally connected servers
2301 if needed. Normal server will send JOIN notify to its local client
2302 on same channel when received this packet. Added also corresponding
2303 sending function silc_server_send_new_channel_user to sent the
2306 * Added boolean route argument to send_notif_to_channel and
2307 packet_send_to_channel functions to attempt to route the packet
2308 if it is TRUE and send only locally if it is FALSE.
2310 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * silc_server_replace_id now broadcasts the received replace ID
2313 packet if it is not broadcast packet already. The router must
2314 broadcast to inform other routers about changed ID.
2316 * Added backpointer to server's router into SilcServer context in
2317 silcd/server_internal.h.
2319 * Fixed silc_server_packet_broadcast to send correct broadcast
2322 * The channel key is now distributed to the local client as soon
2323 as it is received from the router (in router environment) so that
2324 no other packet may be sent for the channel until client has
2327 * silc_server_remove_channel_user now broadcasts the received
2328 Remove Channel User packet if it is not broadcast packet already.
2329 The router must broadcast to inform other routers about removed
2332 * Added users field into SilcPacketContext that is a reference count
2333 of the context. One can increase the reference count by calling
2334 silc_packet_context_dup which is now changed to just increase the
2335 reference count instead of duplicating the data. The reference
2336 count is decresed by calling silc_packet_context_free that will
2337 free the data after the reference count hits zero.
2339 For now on the packet context and everything allocated into it
2340 (including the raw packet from network) must be freed by calling
2341 the new silc_packet_context_free function. Added also new function
2342 silc_packet_context_alloc that must be used now to allocate the
2343 context. This also means that if a routine is asynchronous from
2344 silc_[client/server]_packet_parse_type the packet context must
2345 be duplicated by calling silc_packet_context_dup. Otherwise it
2346 gets free'd after silc_[client/server]_packet_parse_type returns.
2347 Also, one must remember that if packet is duplicated then its
2348 reference count must be decresed by calling the free function as
2349 many times as it was duplicated.
2351 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2352 from both client and server.
2354 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Made joining to a channel working in router environment.
2358 * Cleaned up JOIN command on server side and create function
2359 silc_server_command_join_channel internal routine to make the
2362 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Changed silc_command_pending list to SilcDList. Also, added
2365 `ident' field to SilcServerCommandPending structure to identify
2366 the reply and to call correct callback.
2368 Added silc_server_command_pending_check function to replace the
2369 corresnponding macro. The silc_command_pending list is not
2372 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2373 to set identifier to previously allocated Command Payload. It
2374 is used to set identifier for command when resending Command
2377 * Added silc_command_payload_encode_payload to encode Command
2378 Payload buffer from SilcCommandPayload structure.
2380 * Added silc_argument_payload_encode_payload to encode Argument
2381 payload buffer from SilcArgumentPayload structure.
2383 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Changed WHOIS command to support router connection on server side.
2386 The whois request is always sent to router unless the server is
2387 standalone server. After server has received the reply from the
2388 router will it send the reply to the client.
2390 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2391 broadcast received broadcast packet. The function is used only
2392 by router. The broadcast packet is always sent to the router's
2395 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2396 render given ID to printable string, for log files for example.
2398 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Made basic router to router connections working. At least they
2401 can now connect to each other but nothing really works the way
2402 they are supposed - yet.
2404 * Added new initiator token to RouterConnection configuration
2405 file in silcd/serverconfig.[ch]. It is used to tell whether we
2406 are the initiator to the remote router or whether we'll expect
2407 the other end to connect.
2409 * Moved registering of listener task to silc_server_init, hence
2410 the server starts listenning as soon as it is run, even if it
2411 does not have connections to other routers. Let's see how well
2414 * Changed default connection retry timeouts for more suitable in
2417 * Removed cipher and such arguments from silc_idlist_add_client
2418 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2419 Added new function silc_idlist_add_data to add the keys and stuff
2422 * Added SilcIDListData structure and added it to SilcClientEntry
2423 and SilcServerEntry as their first field in the structure. This
2424 way we can explicitly cast the ID entries to the SilcIDListData
2425 structure and get common data for the entries. In past, we had
2426 to first check what type of connection it is and then cast it to
2427 correct ID entry type. Now, we can directly cast the opaque
2428 pointer to the SilcIDListData (no matter what ID entry it actually
2429 is) and get the data needed.
2431 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2434 in some circumstances even if threre were timeout tasks, though not
2435 IO tasks, but tasks anyway. Now fixed.
2437 * Defined SilcServerConnection structure to hold connection specific
2438 stuff about directly connected servers and routers. The definition
2439 is currently in silcd/server_internal.h. I thought about having
2440 a bit more important role fro this struct but for now it is used
2441 only when connecting to other server (or router actually).
2443 * Added connecting retry support in server when connecting to
2444 router(s). The retry feature implement exponential backoff
2445 algorithm. Also, added SilcServerParams structure to hold default
2446 parameters for server. For now, it include these retry settings
2447 and are hard coded. After server is moded to be as Silc Server
2448 Library this structure will be more important.
2450 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Changed client librarys channel->clients table to SilcList and
2453 changed code accordingly.
2455 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Changed client's channel table to SilcList and changed code
2458 accordingly. Also changed SilcChannelClientEntry to include back-
2459 pointer to the channel so that client entry can use that structure
2460 as list as well and we have fast cross-reference to the channel.
2461 This change dramatically decreased the complexity of channel
2462 handling with client entry and vice versa (removed one extra
2463 loop when searching for channel entry from many functions).
2465 * Changed server->sim from table to SilcDList and changed code
2468 * NAMES command can now be used from user interface. It will show
2469 the user list on the channel, neatly.
2471 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2472 Code now saves realname of the user if it becomes available.
2474 * Renamed configure.in to configure.in.pre and made ./prepare
2475 script to automatically add correct version string to
2476 configure.in which it creates from configure.in.pre.
2478 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * NAMES command reply now shows users mode with the nickname when
2483 * Moved silc_client_ch[u]mode[_char] functions from
2484 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2485 place sucks, they are utility functions and should be in some
2488 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2490 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2493 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Added TRQ (efficient deque and list library) into lib/trq. This is
2498 a very good list library that is currently used in the SILC. Defined
2499 SilcList API over the library because I didn't like the API very
2500 much. See lib/trq/silclist.h for the API and examples of how to
2501 use the API. Fixed various places in the code to use the new
2502 SilcList API. The SilcList is meant for lists that has a structure
2503 already defined as a list. It is not suitable to add just some
2504 context to the list (in TRQ, the context is the list actually).
2506 So, I defined SilcDList that can be used for the purpose where
2507 predefined list structure does not exit. This can be used as
2508 such list. Now some context just can be added to the SilcDList.
2509 Currently this list is not used in the SILC just yet, though there
2510 are a lot places where this can replace dynamically allocated
2511 tables and I will fix these places, later, to use SilcDList.
2512 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2513 and use TRQ internally).
2515 Also fixed some annoying warning messages that the original TRQ
2516 code generated. Also minor changes to TRQ's Makefile.in.
2518 * Added support for querying by Client ID to both WHOIS and
2519 IDENTIFY commands into server, as required by the protocol.
2521 * Removed method function pointers from SilcBuffer structure. They
2522 weren't used to anything and just increased the context size for
2523 no good reason. This change also made silc_buffer_alloc and
2524 silc_buffer_free functions inline functions.
2526 * Disabled command flooding detection support until it's fixed so
2527 that it accepts commands in but does not execute them more than once
2530 * Added silc_net_localhost(), to return local hostname, into
2531 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2532 that must be initialized before calling silc_client_init.
2534 * Added new function: silc_server_send_notify_on_channels to send
2535 notify messages to all channels client has joined. It is assured
2536 that the message is sent only once per client.
2538 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2539 lib/silcutil/silcutil.[ch] as silc_format function. The new
2540 function is generic and is used by server as well, not only by
2541 the logging routines.
2543 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2544 the provided version string was not acceptable. Added new function:
2545 silc_ske_check_version into lib/silcske/silcske.h. The function
2546 must be implemented by the application (client or server) and it
2547 does not reside in the SKE library. The function checks the version
2548 string remote end sent.
2550 * Added back pointers (to opaque context and to SilcSocketConnection)
2551 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2553 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2554 duplicate packet context structure.
2556 * Changed `notify' client operation to send same arguments as client
2557 receives from server except for ID's. ID's are mapped to correct
2558 ID entry and that is returned. Also, if channel entry is not sent
2559 by server but the notify is for channel the channel entry is sent
2560 to application (otherwise application doesn't know that it is for
2561 channel (library gets it from packet's Destination ID)).
2563 * Added silc_client_remove_from_channels into client library to
2564 remove a client from all channels it has joined to. Used when
2565 received SIGNOFF notify from server. Added also new function
2566 silc_client_replace_from_channels to replace old ID entry with
2567 new ID entry on all channels. Used when received NICK_CHANGE
2570 * Fixed ID Cache list handling in silc_idlist_get_client in
2571 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2572 to get (or query) client by ID.
2574 * Updated TODO list.
2576 * Added connection authentication status message defined by the
2577 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2578 support for these into the code in client and server side.
2580 * Added generic function silc_client_send_command to send any command
2581 with variable argument list. Application should use this function
2582 to send commands if the command functions provided by the library
2583 does not suite for the application's user interface needs.
2585 * Added new `failure' client operation. Application is notified about
2586 received failure packet if client is executing a protocol. In this
2587 case the protocol's execution has failed.
2589 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2590 is required by the protocol.
2592 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2593 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2596 * Added status flag to SilcSKE object to indicate realtime status
2597 of the SKE protocol.
2599 * Application receives now exactly same command reply arguments as
2600 the library receives from server. However, if ID is received the
2601 corresponding ID entry is returned to the application (eg. Client
2602 ID is mapped to correct SilcClientEntry entry and that is returned).
2603 Changed command_reply client operation due to this change.
2605 * Changed all ID's in commands and in command replys as ID Payloads.
2606 Change affected both client and server side codes.
2608 All ID's sent in SILC network (with execption of ID's in SILC
2609 Packet header) are sent in ID Payload to support variable length
2612 * Server now notifies nick changes and notifies all clients on
2613 the channels about the new nickname (about the new Client ID,
2616 * Implemented CMODE command to change channel modes. Supports all
2617 channel modes defined by the protocol specs except ban and invite
2618 lists. (Also, private channel key mode is supported but support for
2619 setting private channel key in client is missing, thus, this mode
2620 has no effect on client side (except that server requires that the
2621 client uses private channel key and normal channel traffic does not
2624 Also, invite mode works per se, but INVITE command does not work
2625 yet correctly, so you can set channel as invite only channel but
2626 inviting clients to the channel does not work (it is yet to be
2627 thought what's the best way to do it).
2629 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2630 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2631 Implemented CUMODE command to change user's mode on the channel.
2632 Supports all modes defined by the protocol specs.
2634 * Added NAMES command reply to return users modes on the channel.
2636 * Removed unnecessary and slow ciphers from lib/silccrypt.
2638 * Set SO_KEEPALIVE option to connection sockets by default.
2640 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2642 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2643 redefined the Notify Payload into protocol specs.
2645 * Added silc_id_payload_parse_id to get ID directly from raw
2648 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2651 accept searching by Client ID as well.
2653 * Added support for LEAVE and SIGNOFF notify types in client library.
2655 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2656 to parse ID Payload from raw data.
2658 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added flags parameter into silc_ske_assemble_security_properties
2661 function in lib/silcske/silcske.[ch].
2663 * Changed notify client operation to fit better for notify messages
2664 sent by server. The notify payload received from server is now
2665 passed to the application (after parsing it to SilcNotifyPayload).
2666 It is application's responsibility to retrieve the arguments
2667 from the payload and show the message the way it wants. The message
2668 sent by server is implementation specific.
2670 * Changed public keys to comply with the protocol specification.
2671 Old public keys are not supported anymore and are not compatible.
2673 * Removed nickname from Channel Payload as the latest draft removed
2674 it. The client must resolve the nickname from the NAMES command
2675 reply received when it joined the channel.
2677 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2679 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Fixed some errors in protocol specification drafts.
2683 * Created lib/silccore/silcnotify.c to implement Notify Payload
2684 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2685 generic payloads described by protocol specifications. The file
2686 includes implementations for ID Payload and Argument Payload.
2688 * Changed Command Payload implementation to use the new Argument
2689 Payload. Changed command_xxxx_payload to command_payload_xxxx
2690 to comply with SILC coding conventions.
2692 * Added suppport for Argument Payload handling in Notify Payload
2693 implementation as protocol requires it. Added the new support
2694 into server and client lib as well.
2696 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2698 * Added support for multiple nicknames on same channel. [n] is
2699 added locally to the nickname if there are more than one same
2700 nicknames on the channel.
2702 * Server now sends all nicknames that matched WHOIS request.
2703 Client also shows the list received from server.
2705 * Added TOPIC command to client side. User can now set and show
2706 current topic on channel.
2708 * Added MOTD command to client and server. Also, server sends the
2709 motd when client connects to the server.
2711 * Changed version strings to comply ISO 8601.
2713 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Fixed protocol error handling in client library. It should now
2716 cope even if the SKE fails for some reason.
2718 * Made new protocol specification drafts for submitting to IETF.
2720 * Implemented TOPIC command to server in silcd/command.c.
2722 * Added two new notify types into lib/silccore/silcnotify.h:
2723 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2724 notify nickname change and topic setting/change on a channel.
2726 * API change of command_reply operation in client library. The
2727 application gets now the status type received from server as well.
2729 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2733 * Cras fixed and optimized the packet handling even further and
2734 it should work now. Minor change to the prototype of function
2735 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2737 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added new function into lib/silcutil/silcschedule.[ch]:
2740 silc_schedule_with_fd to select() a specified fd. The function
2741 returns after timeout expires or data arrives or goes. The
2742 function is used by packet routines to wait that all data is
2743 received from network.
2745 * Fixed data reading from network in lib/silccore/silcpacket.c.
2746 The code now assures that all data is read from the fd and then
2747 continues packet processing. This was a bug fix since the code
2748 used to drop some data in some circumstances.
2750 * Added new function into lib/silcclient/client.[ch]:
2751 silc_client_start_key_exchange to start key exchange after
2752 connection has been established to server. The code internally
2753 now uses this funtion but its main purpose was to provide it
2754 for applications that perform their own connecting. After
2755 application has created a connection it merely calls this
2756 function to start the key exchange between client and server.
2757 The library takes care of everything else after that.
2759 Updated also lib/silcclient/README to explain the usage of
2762 * Do not send to application information that connection has
2763 been established. Application gets notified it by connect
2766 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Applied cras's patch to add silc_schedule_one function. The
2769 function runs scheduler once and returns.
2771 * Fixed the scheduler after cras messed it up. The timeout
2772 handling works now as it's supposed to work.
2774 * Added into lib/silccore/ silcnotify.h to include notify
2775 message types support. Changed silc_server_send_notify*
2776 functions, in server.[ch], to support those new notify types.
2777 Added the support for the notify types into client library,
2778 as well. Added new notify client operation into ops.h in
2781 * Changed silc_server_packet_send_to_channel to send normal
2782 packets instead of just channel message packets. The function
2783 is now used to send the notify packets to channels. It is not
2784 used to send channel message packets anymore, as server never
2787 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2788 va_arg()s as it seems to require it nowadays. I guess, if SILC
2789 is compiled with older va_arg() the new code should work anyway.
2791 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Splitted core library. Core library (lib/silccore) includes
2794 now only SILC protocol specific core (and common) components.
2795 Created new utility library (lib/silcutil) that includes more
2796 generic purpose stuff. The stuff for util library was taken
2797 from the old core library. This was minor and easy split.
2799 * Created SILC Client Library (lib/silcclient) that includes
2800 implementation of the SILC client without user interface. This
2801 was major move from silc/ directory. The code has been changed
2802 so that it is transparent towards the user interface. The
2803 silc/ directory includes now the same user interface as before
2804 and it uses the new client library. Read lib/silcclient/README.
2805 Basicly, the client library performs everything else related
2806 to SILC except user interface handling. Also, configuration
2807 files are considered to be part of user interface and library
2808 does not handle them.
2810 This change also changed a lot of structures, function naming etc.
2811 Most important change was that SilcClientWindow object was
2812 renamed to SilcClientConnection in the client library. Created
2813 also new file lib/silcclient/ops.h. Also added new files
2814 silc/local_command.[ch] and silc/client_ops.[ch].
2816 All these changes were made to make it easier for user interface
2817 designers to create what ever user interface for the SILC client
2820 It is also expected that the server will be moved to lib
2821 directory as well and SILC Server Library will be created;
2822 sometimes in the future.
2824 * Removed Local commands from lib/silccore/silccommand.h as
2825 they are application specific and new client library does not
2826 handle any of those anymore.
2828 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2829 old client implementation in silc/.
2831 * Added support for callback functions in SILC_LOG_* macros.
2832 Application can now set its own callbacks that will be called
2833 instead of using the default functions that will always print
2834 the debug messages to stderr (or stdout). Also, debugging can
2835 now be disabled by setting silc_debug to FALSE and re-enabled by
2836 setting it to TRUE. Note, that logging will still work even
2837 if debugging is disabled.
2839 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2840 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2841 silc_log_reset_debug_callbacks.
2843 * To enable debugging in silc client one must give now -d
2844 option on command line.
2846 * Changed silc_schedule_init to automatically allocate task queues
2847 if they are not allocated before calling it.
2849 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Added GMP 3.1 into math library.
2853 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2856 a channel in SILC network. The packet is used by servers and
2857 routers to notify other routers that user has left a channel.
2858 This little feature was missing until now. Added the feature
2859 to protocol specification as well.
2861 Added functions: silc_server_send_remove_channel_user and
2862 silc_server_remove_channel_user into server.[ch].
2864 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2865 lib/silccore/silcpacket.h. However, they are not implemented
2868 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Fixed joining to a channel and sending channel messages
2871 between server and router. The channel message sending should
2872 now work inside a cell.
2874 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Fixed the private message sending between server and router.
2877 The private message sending should now work inside a cell.
2879 * Added silc_server_replace_id into server.[ch] to replace
2880 existing ID in the SILC network.
2882 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2883 and silc_idlist_replace_server_id into idlist.[ch] in server.
2885 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Fixed the server to server connections. Server can again now
2888 connect to router. Router to router connections probably does
2891 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Added dynamic protocol registering support. Now protocols can
2894 registered and unregistered on the fly. Patch by cras.
2896 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Added lib/contrib directory to hold routines that some platforms
2899 don't have but are needed by SILC.
2901 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2902 into lin/contrib to provide getopt() and getopt_long() for
2903 those who don't have it.
2905 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Added AWAY command to client. When away message is set and
2908 client receives a private message packet the client automatically
2909 replies to the sender with the away message.
2911 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2912 bug seemed to be the cause of recent problems when compiling
2915 * Added version detection support to SKE protocol specification
2916 and added the new changes to the SKE implementation as well.
2917 There were other minor changes in the SKE protocol as well.
2919 Many changes in lib/silcske/silcske.[ch] and in
2920 lib/silcske/payload.[ch].
2922 * Added ^U functionality, clear input line. Patch from cras.
2924 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Mainly small bugfixes on core library. Fixed some debugging
2927 logging and buffer overflow in silclog.c.
2929 * Updated config.sub and config.guess on the distribution tree.
2931 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Added command lagging support in server. Client may execute
2934 commands now only once in two seconds.
2936 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Optimized packet reception. MAC computation and checking is now
2939 also more optimized. A lot previously duplicated code is now
2940 used as generic by both client and server.
2942 * Fixed key pair generation in clientutil.c
2944 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Added into lib/silccore/silcbufutil.[ch] new function;
2947 silc_buffer_realloc.
2949 * Moved generic packet sending/encryption functions to
2950 lib/silccore/silcpacket.[ch] from client and server. Some
2951 rewriting of the functions.
2953 * Moved all generic packet reception/decryption functions to
2954 lib/silccore/silcpacket.[ch] from client and server. The
2955 packet processing is now much cleaner in both client and server.
2956 These were major changes in both client and server.
2958 * Created many common functions in server to do packet sending.
2959 Previously code were duplicated a lot, this has been removed
2962 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Rewrote major parts of the ID cache system. Don't know
2965 whether it is better now or not but at least the API is more
2968 * Major rewrite on ID cache stuff on client because of the ID
2969 cache API changes. Added idlist.c to client.
2971 * Also major rewrite on ID cache stuff on server as well.
2972 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2973 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2974 in hand, instead they are all put into the ID cache system now.
2975 All server_idlist_* routines uses ID cache now instead of
2976 traversing its own lists (those lists does not exist anymore).
2977 SilcIDList though still exists. Also, SilcXXXEntry's are
2980 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Finally made the SKE implementation compliant to the protocol
2983 specification. All mp integers are now binary encoded as
2984 opposed being HEX encoded.
2986 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2989 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2990 functions: silc_[encode/decode]_pem. Also added function
2991 silc_encode_pem_file to PEM encode with newlines ('\n') for
2994 * SILC public keys are now encoded either PEM or binary. Same
2995 option is for private keys as well. By default private keys
2996 are binary encoded and public keys PEM encoded. Silly HEX
2997 encoding were removed.
2999 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3000 function to create fingerprints.
3002 * Fixed a bug in SHA1; does not change the original data anymore.
3004 * Partly implemented INFO command on client and server side.
3005 Fixed CLEAR command. Changes to SERVER command; show current
3006 server(s) when giving command without arguments. Added
3007 VERSION command to client.
3009 * Added check to server that unregistered connections cannot
3010 execute commands (unless it is specificly allowed).
3012 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Fixed screen refresh.
3016 * Fixed channel joining bug from client. On some circumstances
3017 client tried to join to a channel it had already joined.
3019 * Added public key verification process into client's protocol.c.
3020 The client now verifies the public key from user and saves
3021 it into ~./silc/serverkeys/ directory.
3023 Added into: clientutil.[ch]: silc_client_verify_server_key.
3025 * Changed SKE protocol's silc_ske_initiator_finish function
3026 to accept callback function that verifies the received public
3027 key. Removed old silc_ske_verify_public_key function.
3029 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3032 silc_pkcs_private_key[_data]_set.
3034 * Made the password and public authentication more cleaner in
3035 server's protocol.c.
3037 * Removed historic and obsolete protocol `channel_auth' from
3038 both client and server.
3040 * Removed wrong way of sending command status messages from
3041 server to client in server's command.c. The old way violated
3042 protocol specification.
3044 Changes to silccore/silccommand.[ch]: removed
3045 silc_command_encode_status_payload -> not needed anymore,
3046 changed silc_command_encode_payload_va to accept extra
3047 argument on variable argument list. The argument type must
3048 now be provided to the function. Also, added new function:
3049 silc_command_encode_reply_payload_va which is same as
3050 normal command_encode_payload_va except command status type
3051 is provided as extra argument.
3053 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Added ~./silc directory handling. The directory includes the
3056 public and private keys for the client.
3058 Added silc_client_check_silc_dir, silc_client_create_identifier
3059 and silc_client_load_keys.
3061 * Implemented SILC protocol compliant public key. Added public
3062 and private key saving to and loading from files.
3064 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3065 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3066 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3067 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3068 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3070 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3071 silc_pkcs_load_[public/private]_key.
3073 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added silc_server_get_route (route.[ch]) to get connection
3076 data for the fastest route for given ID.
3078 * Implemented INVITE command on client and server. The command
3079 were re-defined in the SILC Protocol Specification and the
3080 implementation now complies with the specification.
3082 * Implemented PING command on client and server.
3084 * Implemented NAMES command on client and server. The server side
3085 supports currently only normal server not router server yet.
3086 Some changes to NAMES definition in SILC protocol specification.
3088 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Implemented LEAVE command on client and server.
3092 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3093 again. This change was made to the protocol as well. Server
3094 should not violate the protocol specification anymore.
3096 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3099 was tested. SOCKS4 was not but should work anyway.
