1 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Moved the USERS printing from the library to the application.
4 Affected files lib/silcclient/command.c and silc/client_ops.c.
6 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Added channel key re-key support. The re-key is perfomed
11 only by the router and is done once in an hour. Added `rekey'
12 field to the SilcChannelEntry in the server. Affected files
13 silcd/server.c and silcd/idlist.h.
15 * Added silc_task_unregister_by_context into the file
16 lib/silcutil/silctask.[ch].
18 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Added SILC_UMODE_GONE mode to indicate when the client is not
21 present in the SILC network. Added also support to the local
22 command AWAY that will set this mode. Added support of showing
23 "xxx is gone" in WHOIS command. The USERS command shows the
26 * Fixed setting server and router operator privileges in the
27 server's UMODE command. Affected file silcd/command.c.
29 * Merged the SKE KE1 and KE2 payloads into one payload. The
30 new KE payload is equivalent to the old KE2 payload.
32 Cleaned up the SKE Start Payload parsing. It now uses the
33 simple buffer unformatting to do the parsing. A lot faster
36 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
37 to the SKE that is used to indicate whether both of the SKE
38 parties should perform authentication. By default only the
39 responder performs authentication. By setting this flag also
40 the initiator must do authentication. By default it is unset
41 since in normal SKE case, client to server connection, only
42 the responder should do authentication. When doing SKE between
43 two clients both should perform authentication. Updated the
44 code and the protocol specs.
46 * A little fix to IDENTIFY command in the server. Search the
47 client first by hash not nickname. Affected file is
50 * Fixed the silc_client_close_connection to support closing
51 the client to client connections wihtout deleting too much
52 data. Affected file lib/silcclient/client.c.
54 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
55 are received if protocol used to be active but is not anymore
56 the application would crash due to NULL pointer dereference.
57 Affected files silcd/server.c and lib/silcclient/client.c.
59 * Added `hash' field to the SilcClientConnection to include
60 the hash function negotiated in the SKE protocol.
62 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
63 to set the channel founder authentication data. A client can
64 claim the founder rights later by providing the authentication
65 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
66 This way the channel founder can regain the channel founder
67 privileges even it is left the channel. This works only on
68 local server and the client must be connected to the same
69 server to be able to regain the founder rights. Updated the
70 protocol specs accordingly.
72 Added support to the CMODE command in the client to set the
73 founder auth data. Read the README to see how to set it.
75 Added support to the CUMODE command to claim the founder
76 rights. Read the README to see how to do it.
78 Added support for the founder authentication to the Channel
79 Entry in the server. Affected file silcd/idlist.h.
81 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
82 server's CMODE command. Affected file silcd/command.c.
84 * Added the following new functions into lib/silccore/silcauth.[ch]:
85 silc_auth_get_method and silc_auth_get_data.
87 * The server now saves the remote hosts public key to the
88 SilcIDListData pointer. Affected file silcd/protocol.c.
90 * The normal server now does not remove the channel entry from
91 the cache if the founder authentication data is set. It used
92 to remove it if the founder was the last one on the channel on
93 the server and left the channel. The auth data is saved and
94 if the channel is re-joined later the old entry is used with
95 the old auth data. Affected files silcd/command_reply.c and
98 * Removed the `pkcs' field from the SilcIDListData structure
99 in the server; it is not used. Affected file silcd/idlist.h.
101 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Fixed packet processing on slow links. Partial packets were
104 never re-processed because the incoming data buffer was cleared
105 by the application. Application must not directly clear the
106 sock->inbuf, the packet processing routines handle it. Fixed
107 this in client library and in server.
109 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Fixed the WHOIS and IDENTIFY send reply function to really
112 check whether to send list or just one entry. Affected file
115 * Cleaned up the LEAVE command's channel key distribution. The
116 affected file silcd/command.c.
118 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
119 can enforce the channel mode as well. In that case the ID
120 includes the ID of the server. The code now enforces the
121 mode change if the router have different mode than the server.
123 * The notify client operation with CMODE_CHANGE notify can now
124 return NULL client_entry pointer if the CMODE was not changed
125 by client. Application must check for this.
127 * Added <Server ID> argument to INFO command to support server
128 info fetching by Server ID.
130 * Added silc_server_announce_get_channel_users to get assembled
131 packets of channel users of the specified channel. Affected
132 file silcd/server.[ch].
134 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
135 was freed underneath the ID Cache.
137 * Re-announce clients when the server received CHANNEL_CHANGE
138 notify from the router. Affected file silcd/packet_send.c.
140 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
143 crashed since it did not handle the fact that there is no cipher
144 called "3" and didn't check the error condition. Now fixed.
146 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
147 flag. It can be used to send message requests.
149 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Implemented the RESTART command in the client.
153 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
154 notice type messages. Added notice printing to the user
157 * The channel keys are not re-generated if the channel's mode
158 is PRIVKEY, ie private key on the channel exists. Affected
159 files silcd/server.c and silcd/command.c.
161 * Fixed a little bug in channel message delivery when channel
162 private keys are set in the server. Affected file is
165 * Changed the setting on channel->on_channel = TRUE from the
166 silc_client_save_channel_key to the JOIN command reply. The
167 key payload is not received if the private channel key is set.
168 Affected file lib/silcclient/command_reply.c and the
169 lib/silcclient/client_channel.c.
171 * When the CMODE_CHANGE notify is sent and the channel private
172 key mode is removed the channel key must be re-generated in
173 other cells as well. Added this support for the router in the
174 silcd/packet_receive.c.
176 * Added new local command NOTICE to send notice message on
177 channel. Affected file silc/local_command.[ch].
179 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Added new local command ME to the client. It is used to send
182 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
183 some action. Affected file silc/local_command.[ch].
185 * Changed channel_message and private_message client operations
186 to deliver the message flags to the application. Added also
187 the `flags' arguments to the silc_client_send_channel_message
188 and silc_client_send_private_message functions. Affected file
191 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Redefined the Private Message Payload to support private message
194 keys and to support the new private message flags. Updated
195 the protocol specs. Flags makes it possible to have for example
198 * Added new type SilcPrivateMessagePayload and defined an API
199 for it in the lib/silcclient/silcprivate.[ch].
201 * Tested private message private keys successfully. Tested the
202 private message key set, unset and list commands with the new
205 * Redefined the Channel Message Payload to include the channel
206 message flags (equal with private message flags) to support
207 for example CTCP style messages.
209 * Defined some of the message (for channel and private message)
210 flags. Updated the protocol specs and added the flags to the
211 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
213 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Added SilcKeyAgreementStatus type to the key agreement routines
216 to indicate the current status and error if one occured.
217 The status types are defined in the lib/silcclient/silcapi.h.
219 * Added new local command KEY that is used to set and unset private
220 keys for channels, set and unset private keys for private messages
221 with remote clients and to send key agreement requests and
222 negotiate the key agreement protocol with remote client. The
223 key agreement is supported only to negotiate private message keys,
224 it currently cannot be used to negotiate private keys for channels,
225 as it is not convenient for that purpose.
227 * Fixed a minor pending callback setting bug in the function
228 silc_client_get_client_by_id_resolve, now the function works.
229 Affected file lib/silcclient/idlist.c.
231 * Added function silc_net_get_local_port to get local bound
232 port by socket. Added to lib/silcutil/silcnet.[ch].
234 * Added `sockets' and `sockets_count' fields to the SilcClient
235 object. They hold the sockets of the listenning sockets in
236 the client. Listenning sockets may be for example the key
237 agreement server. Affected file lib/silcclient/client.[ch].
238 Added functions the silc_client_add_socket and the
239 silc_client_del_socket. They are exported to the application
242 * Added ~./silc/clientkeys to support other client's public keys.
244 * Renamed verify_server_key client operation to verify_public_key
245 and added one argument to indicate the type of the connection
246 (server, client etc.).
248 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Added silc_server_connection_auth_request to handle the
251 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
252 silcd/packet_receive.[ch].
254 * Added silc_server_send_connection_auth_request into the
255 silcd/packet_send.c to send the connection auth request packet.
257 * Cleaned up the silcd/protocol.c a bit and fixed some memory
260 * Fixed the public key authentication in responder side in the
261 server. The `auth_data' pointer includes the SilcPublicKey
262 not the path to the public key. Affected file silcd/protocol.c.
264 * Implemented the public key authentication in the initiator side
265 in the server. Affected file silcd/protocol.c.
267 * Removed the [RedirectClient] config section from the server
268 configuration. Is not needed and I don't want to implement it.
270 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Cleaned up the CMODE command in the server. It now works
273 correctly and supports all the modes defined in the protocol.
274 Affected file is silcd/command.c.
276 * Added `hmac_name' field to the SilcChannelEntry in the server
277 to hold the default HMAC of the channel. It can be set when
278 creating the channel (with JOIN command). Affected files
281 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
282 type to indicate the change of the current cipher and hmac
283 on the channel. Client can safely ignore the <cipher> argument
284 (if it chooses to do so) since the CHANNEL_KEY packet will
285 force the channel key change anyway. The <hmac> argument is
286 important since the client is responsible of setting the new
287 HMAC and the hmac key into use.
289 * Fixed the CMODE command in the client library as well.
291 * Tested CMODE command in router environment successfully.
293 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Show the version of the remote client (or server) when connecting
296 to the server. It is logged to the log file. Affected file
299 * Fixed the KILLED notify handling in the client library. The
300 client must be removed from all channels when receiving the
303 Also, do not remove the client entry when giving the KILL
304 command but when the KILLED notify is received.
306 * Removed silc_idlist_find_client_by_nickname from the server.
307 Not needed anymore. Affected files silcd/idlist.[ch].
309 * Implemented the CHANNEL_CHANGE notify type handling to the
310 server. Affected file silcd/server.c.
314 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

317 notify between routers.
319 * Implemented the INVITE command correctly to the server.
321 * Implemented the INVITE notify type handling in the server.
323 * Implemented the INVITE command to the client library and on the
326 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Added function silc_server_get_client_resolve to find the
329 client entry by ID from all ID lists and then resolve it
330 (using WHOIS) if it cannot be found. Affected file is
333 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Implemented the BAN command to the client library.
337 * The JOIN command in the server now checks the invite list
340 * Changed the silc_command_reply_payload_encode_va and the
341 silc_command_payload_encode_va to support that if argument is
342 NULL it ignores and checks the next argument. Affected file
343 lib/silccore/silccommand.c.
345 * Added silc_server_send_notify_ban to send the BAN notify
346 type between routers.
348 * Chaned the silc_notify_payload_encode to support that if
349 argument is NULL it ignores and checks the next argument.
350 Affected file lib/silccore/silcnotify.c.
352 * Tested ban lists in router environment successfully.
354 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Implemented BAN command to the server, in silcd/command.[ch].
358 * Removed the BAN and INVITE_LIST modes from the CMODE command
361 * Added function silc_string_match to regex match two strings.
362 Affected files lib/silcutil/silcutil.[ch].
364 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Redefined parts of the SilcChannelEntry in the server to support
367 the new ban and invite lists.
369 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Redefined the INVITE command. The same command can be used to
372 invite individuals to the channel but also to manage the invite
373 list of the channel (to add to and remove from the invite list).
374 Updated the protocol specs.
376 * Added new command SILC_COMMAND_BAN that can be used to manage
377 the ban list of the channel. Updated the protocol specs.
379 * Removed the channel modes: the SILC_CMODE_BAN and the
380 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
381 in the CMODE command. The equivalent features are now available
382 using INVITE and BAN commands. Updated the protocol specs.
384 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
385 in the network about change in the current ban list. The notify
386 type is not used by the client.
388 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
389 support the invite lists.
391 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Added new function silc_string_regexify that converts string
394 including wildcard characters into regex string that can
395 be used by the GNU regex library. Added into the file
396 lib/silcutil/silcutil.[ch].
398 Added silc_string_regex_combine to combine to regex strings
399 into one so that they can be used as one regex string by
400 the GNU regex library. Added into the file
401 lib/silcutil/silcutil.[ch].
403 Added silc_string_regex_match to match two strings. It returns
404 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
406 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
408 * Imported GNU regex to the soruce tree into lib/contrib.
409 Fixed some compiler warning from the regex.c.
411 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Fixed MOTD command in the server to work in router environment.
415 * Fixed the MOTD command in the client library to support
416 the server argument in the command.
418 * Added `nickname_len' argument to the silc_idlist_add_client
419 in the server, as the `nickname' argument may be binary data
422 * Added silc_idlist_get_channels to return all channels from
425 * Implemented LIST command to the server. Affected file is
428 * Implemented the LIST command to the client library and on the
431 * Added [<user count>] argument to the LIST command reply.
432 With private channels the user count is not shown.
434 * Updated TODO and README.
436 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * The client entry's data.registered must be TRUE even with
439 global client entry on global client list. The data.registered
440 is used to check whether the client is anymore in the network,
441 for example with WHOWAS command so it must be valid.
443 * Fixed the WHOWAS command in the server. It now actually works
444 in router environment. Added function into silcd/command_reply.c
445 silc_server_command_reply_whowas_save.
447 * Added silc_idlist_purge function to the silcd/idlist.c
448 to periodically purge the ID Cache.

451 environment. Added <server name> argument to the INFO command
452 reply. Updated the protocol specs.
454 * Fixed minor bug in silc_idcache_purge to not purge if the
455 expire value is zero.
457 * Fixed various bugs in WHOIS and IDENTIFY command handling as
458 they were buggy because of the WHOWAS information.
460 * Fixed local command MSG to handle the async resolving of
461 the remote client properly. It used to fail the first MSG.
462 Affected file silc/local_command.c.
464 * Added `data_len' field to SilcIDCache context.
466 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Update TODO. Todo in commands in the server.
470 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
473 used by routers as broadcast packet to inform other routers
474 about the changed user mode.

477 silcd/packet_receive.c. Added the function
478 silc_server_send_notify_umode to the silcd/packet_send.[ch].
480 * Added new generic Channel Payload and deprecated the New Channel
481 Payload. The New Channel Payload is now the generic Channel
484 * Added new argument `mode' to the silc_server_send_new_channel
485 as it is required in the Channel Payload now.
487 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
488 and created a new and real SilChannelPayload to represent the
489 new generic Channel Payload. Implemented the encode/decode
490 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
492 * Added silc_server_get_client_channel_list to return the list
493 of channels the client has joined for WHOIS command reply.
494 Affected file silcd/server.[ch].
496 * Implemented the channel list sending in the WHOIS command reply
497 in server and in the client.
499 Implemented the channel list displaying on the user interface
500 as well. Affected file silc/client_ops.c.
502 * Added silc_channel_payload_parse_list to parse list of Channel
503 Payloads. It returns SilcDList list of SilcChannelPayloads.
504 Client for example can use this function to parse the list of
505 channels it receives in the WHOIS command reply. The caller
506 must free the list by calling silc_channel_payload_list_free.
507 Affected files lib/silccore/silcchannel.[ch].
509 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Added one new argument <user mode> to the WHOIS command reply
512 to return the mode of the user in SILC. Updated the protocol
515 Implemented it to the server and client.
517 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Fixed the mode printing on the user interface on joining.
520 Affected file silc/client_ops.c.
522 * Implemented the UMODE command and user modes in general to the
523 client library and to the user interface.
525 * Implemented the UMODE command to the server.
527 * The server now sends UNKNOWN_COMMAND error status if client sends
528 unknown command. Affected file silcd/command.c.
530 * All server commands now handle the command identifier the right
531 way when sending the command reply to the client. The client can
532 use to identify the command replies with the identifier.
534 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Added silc_server_get_client_route to resolve the route to
537 the client indicated by the client ID. Affected file is
540 * Added silc_server_relay_packet as general function to relay
541 packet to arbitrary destination. This deprecates functions
542 like _send_private_message_key, _relay_notify etc. Affected
543 file is silcd/packet_send.[ch].
545 Removed silc_server_send_key_agreement,
546 silc_server_send_private_message_key and
547 silc_server_packet_relay_notify functions from the file
548 silcd/packet_send.[ch].
552 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
553 server. Affected file silcd/packet_receive.[ch].
555 * Implemented the KILL command to the client. Implemented the
556 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
557 Affected files lib/silcclient/command[_reply].c and
558 lib/silcclient/client_notify.c. Implemented the KILL notify
559 printing in the user inteface.
561 * Fixed a lot silc_parse_nick memory leaks from the client
562 library in the file lib/silcclient/command.c.
564 * Changed the silc_server_send_notify_on_channels's `sender'
565 argument from SilcSocketConnection to SilcClientEntry to
566 check the sender as entry and not as connection object and not
567 to send to the client provided as argument. The affected file
568 is silcd/packet_send.[ch].
570 * The notify packets that are destined directly to the client used
571 to not to be processed by the server. Now changed that and the
572 server processes all notify packets. After relaying the packet
573 to the client the notify packet is processed in the server.
575 * The silc_server_free_client_data now checks whether there is
576 pending outgoing traffic for the client and purges the data to
577 the network before removing the client entry.
579 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
582 an client is killed from the SILC Network. Updated the protocol
585 Added new function silc_server_send_notify_killed to the
586 silcd/packet_send.[ch].
588 * Added function silc_server_packet_relay_notify to relay notify
589 packets that are destined directly to a client. In this case
590 the server does not process the notify packets but merely relays
591 it to the client. Affected file silcd/packet_send.[ch].
593 Added also silc_server_packet_process_relay_notify to check
594 whereto relay the notify. Affected file is
595 silcd/packet_receive.[ch].
597 * Implemented the KILL command to the server.
601 * Added the backup schema desgined last fall to the protocol
602 specs for everyone to see. The specification is in the
603 *-spec-xx.txt draft and the packet type definitions for the
604 backup routers is in *-pp-xx.txt draft. Thusly, added also
605 new packet type SILC_PACKET_CELL_ROUTERS.
607 * A big security problem in the implementation discovered. The
608 signoff of an client did not cause new channel key generation
609 which it of course should've done. The channel keys must be
610 always re-generated when client leaves (or signoffs) the channel.
611 The silc_server_remove_from_channels funtion now handles
612 the channel key re-generation.
614 * Added `sender' argument to the silc_server_send_notify_on_channels
615 to not to send the client provided as argument. Affected file
616 silcd/packet_send.[ch].
618 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Implemented OPER and SILCOPER commands into the server and
623 * Added silc_auth_verify and silc_auth_verify_data to verify
624 the authentication directly from the authentication payload.
625 It supports verifying both passphrase and public key based
626 authentication. Affected file lib/silccore/silcauth.[ch].
628 * Added `hash' field to the SilcIDListData structure. It is the
629 hash negotiated in the SKE protocol. Affected file is
632 * Slight redesigning of the SilcAuthPayload handling routines.
633 Do not send SilcPKCS but SilcPublicKey as argument.
635 * Implemented the public key authentication support to the
636 serverconfig. The public key is loaded from the provided path
637 and saved as authentication data to void * pointer. Thus,
638 changed the unsigned char *auth_data to void *auth_data;
640 * Fixed SHUTDOWN command to send the reply before the server
641 is shutdown. :) Affected file silcd/command.c.
643 * Fixed fatal bug in CONNECT command. The hostname was invalid
644 memory and server crashed. Affected file silcd/command.c.
646 * Fixed fatal bug in CLOSE command. The server_entry became
647 invalid but was referenced later in the command. Affected file
650 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Fixed fatal bug in failure packet handling. Server ignored
653 the failure and thus crashed when it came.
657 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
660 that the command may be executed only once in (about) 2 seconds.
661 The old SILC_CF_LAG flag is same but allows command bursts up
662 to five before limiting.
664 Added the support for CF_LAG and CF_LAG_STRICT flags to the
665 server code. Various commands now includes the CF_LAG_STRICT
666 flag to disallow any kind of miss-use of the command.
668 * Fixed the silc_buffer_unformat to not to allocate any data
669 if the length of the data is zero. It used to allocate the
670 length + 1. Affected file lib/silcutil/silcbuffmt.c.
672 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Changed the format of AdminConnection configuration section
675 in the server. Added username of the admin to the format.
676 Affected files silcd/serverconfig.[ch].
678 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
679 to return admin configuration data by host, username and/or
682 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Implemented WHOWAS command to the server. Added the functions:
686 silc_server_command_whowas_parse,
687 silc_server_command_whowas_send_reply,
688 silc_server_command_whowas_from_client and
689 silc_server_command_whowas_from_server
691 * Added <Client ID> argument to the WHOWAS command reply. Updated
692 the protocol specs accordingly.
694 * Implemented WHOWAS command and command_reply to the client
697 Implemented the WHOWAS printing on the user interface.
699 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added new argument to the WHOWAS command reply, the real name.
702 It is an optional argument. Updated the protocol specs.
704 * Added SilcIDCacheDestructor callback that is registered when
705 the SilcIDCache is allocated. The callback is called when
706 an cache entry in the ID Cache expires, or is purged from the
707 cache. Added into lib/silccore/idcache.[ch].
709 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
710 to destruct the client entries when the cache entry expires.
711 Other ID Cache's in server and in the client library ignores
714 * If the ID Cache entry's `expire' field is zero then the entry
715 never expires. Added boolean `expire' argument to the
716 silc_idcache_add function in the lib/silccore/idcache.[ch].
717 If it is TRUE the default expiry value is used.
719 * Added silc_server_free_client_data_timeout that is registered
720 when client disconnects. By default for 5 minutes we preserve
721 the client entry for history - for WHOWAS command.
723 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
725 * Added support to the server to enforce that commands are not
726 executed more than once in 2 seconds. If server receives
727 commands from client more frequently, timeout is registered
728 to process the commands. Affected file silcd/command.c.
729 Added new function silc_server_command_process_timeout.
731 * Changed NICK_NOTIFY handling in client library to check that
732 if the client's nickname was changed, so there is no need to
733 resolve anything from the server.
735 * Removed error printing from the WHOIS and IDENTIFY commands.
736 If error occurs then it is ignored silently in the client library.
737 The application, however, may map the received error to
738 human readable error string. The application currently maps
739 the NO_SUCH_NICKNAME error to string.
741 * Made the command status message public to the application. Moved
742 them from lib/silcclient/command_reply.c to
743 lib/silcclient/command_reply.h. The application can map the
744 received command status to the string with the
745 silc_client_command_status_message function.
747 * Added check to the server to check that client's ID is same
748 as the Source ID in the packet the client sent. They must
751 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Added dist-bzip hook to the Makefile.am to make bzip2
754 compressed distributions.
756 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Server now enforces the maximum length for the nickname and
759 the channel as protocol specification dictates. 128 bytes for
760 nickname and 256 bytes for channel name.
762 * Moved the WHOIS printing to the application. The client libary
763 does not print out the WHOIS information anymore, the application
764 must do it. Renamed silc_client_command_reply_whois_print to
765 the silc_client_command_reply_whois_save.
767 The client's idle time is also sent to the application now, and
768 the idle is shown on screen.
770 * Added silc_client_command_reply_identify_save to save the
771 received IDENTIFY entries.
773 * Do not check for channel private keys in message sending and
774 reception if the channel does not have the PRIVKEY mode set.
775 Affected file lib/silclient/client_channel.c.
777 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
780 just surfaced after chaning the JOIN procedure.
782 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added silc_client_get_clients_by_list to get client entries
785 from Client ID list, that is returned for example by JOIN
786 and USERS command replies. The application should use this
787 function for example when JOIN command reply is received to
788 resolve the clients already on the channel (library does not
789 do that anymore as USERS command reply is not used in the JOIN
790 procedure anymore). Affected files lib/silcclient/silcapi.h and
791 lib/silcclient/idlist.c.
793 * JOIN command reply and USERS command reply returns now SilcBuffer
794 pointers instead of unsigned char pointers when returning
795 the client list and mode list.
797 * Added <Client ID> argument to the JOIN command reply, mainly
798 for the server to identify for which client the command was
799 originally sent. Updated protocol specs accordingly.
801 * Added SilcDlist private_key pointer to the SilcChannelEntry
802 in the client to support the channel private keys. Affected
803 file is lib/silcclient/idlist.h.
805 * Added SilcChannelPrivateKey argument to the function
806 silc_client_send_channel_message so that application can choose
807 to use specific private ke if it wants to. If it is not provided,
808 the normal channel key is used, unless private keys are set.
809 In this case the first (key that was added first) is used
810 as the encryption key.
812 * Implemented the support for channel private key handling.
813 Implemented the following functions:
815 silc_client_add_channel_private_key,
816 silc_client_del_channel_private_keys,
817 silc_client_del_channel_private_key,
818 silc_client_list_channel_private_keys and
819 silc_client_free_channel_private_keys
821 Affected file lib/silcclient/client_channel.c.
823 * Added the support for the private keys in the channel message
824 sending and encryption and in the message reception and
825 decryption. Affected funtions are
826 silc_client_send_channel_message and silc_client_channel_message.
828 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
830 * Added SKE's key verify callback to the client library's
831 KE protocol context. Affected files lib/silcclient/protocol.[ch].
833 * Removed the statement that server (or router) must send USERS
834 command reply when joining to the channel so that the client
835 knows who are on the channel. Instead, the client list and
836 client's mode list is now sent in the JOIN command reply to the
837 client who joined channel. This is better solution.
839 * Added function silc_server_get_users_on_channel and function
840 silc_server_save_users_on_channel to the silcd/server.[ch].
842 * Removed function silc_server_command_send_users from the
845 * Do not show topic on the client library anymore. The topic is
846 sent in the command reply notify to the application and the
847 application must show the topic now.
849 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Added client searching by nickname hash into the IDENTIFY and
852 WHOIS commands in the server as they were clearly missing from
853 them. Affected file is silcd/command.c.
855 * Fixed a bug in private message receiving in the client library.
856 The remote ID was freed and it wasn't supposed, now it is
859 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Minor fix to the channel payload; allocate the data area, as it
862 needs to be of specific length.
864 * If the key agreement port is zero then the operating
865 system will define the bound port. Affected files are
866 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
868 * Added new function silc_channel_payload_decrypt into the file
869 lib/silccore/silcchannel.[ch].
871 * Moved the channel message etc, check from silc_packet_decrypt
872 to applications. The library calls now a generic
873 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
874 when the packet is either normal or special. This was done to
875 allow more wide range of checking that was not allowed when
876 the code was in library. Now applications can do virtually any
877 checks to the packet and return to the library the decision how
878 the packet should be processed. Affected files are
879 lib/silccore/silcpacket.[ch].
881 Added silc_server_packet_decrypt_check to the server and
882 silc_client_packet_decrypt_check to the client library.
884 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
885 to send with specified source and destination information.
887 * Channel message delivery between routers was broken after the
888 channel key distribution was fixed earlier. The channel key
889 was used be to distributed to other routers as well which is not
890 allowed by the protocol. Now this is fixed and channel keys
891 really are cell specific and the channel message delivery between
892 routers comply with the protocol specification.
894 * Fixed various commands in server to check also the global list
895 for the channel entry and not just the local list. The affected
896 file silcd/command.c.
898 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Added assert()s to buffer formatting and unformatting routines
901 to assert (if --enable-debug) when error occurs. Affected
902 file: lib/silcutil/silcbuffmt.c.
904 * Changed to auto-reconnect to check whether the remote host is
905 router and register the re-connect timeout if it is. It used
906 to check that whether we are normal server, but router must do
907 auto-reconnect with another router as well. Affected file
910 * Removed the [<key len>] option from CMODE command as the cipher
911 name decides the key length, nowadays. See the defined ciphers
912 from the protocol specification.
914 * Added [<hmac>] option to the CMODE command to define the HMAC
915 for the channel. Added SILC_CMODE_HMAC channel mode.
917 * Added [<hmac>] option for the JOIN command so that user can
918 select which HMAC is used to compute the MACs of the channel
921 * Added Hmac field to the Channel Message Payload. The integrity
922 of plaintext channel messages are now protected by computing
923 MAC of the message and attaching the MAC to the payload. The
924 MAC is encrypted. Now, it is clear that this causes some
925 overhead to the size of the packet but rationale for this is that
926 now the receiver can verify whether the channel message decrypted
927 correctly and also when private keys are set for the channel the
928 receiver can decrypt the packet with several keys and check from
929 the MAC which key decrypted the message correctly.
931 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
932 lib/silccrypt/silccipher.[ch].
934 * Added silc_hash_len to return the digest length into the
935 lib/silcrypt/silchash.[ch].
937 * Rewrote parts of Silc Channel Payload interface in the
938 lib/silccore/silcchannel.[ch]. The encode function now also
939 encrypts the packet and parse function decrypts it.
941 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Fixed a minor formatting bug in the SKE's key material processing.
944 It actually might have processed the keys wrong way resulting
947 * Redefined the mandatory HMAC algorithms and added new algorithms.
948 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
949 and hmac-md5 truncated to 96 bits. The mandatory is now
950 hmac-sha1-96. Rest are optional (including the one that used
951 to be mandatory). Rationale for this is that the truncated HMAC
952 length is sufficient from security point of view and can actually
953 make the attack against the HMAC harder. Also, the truncated
954 HMAC causes less overhead to the packets. See the RFC2104 for
957 * Added new [hmac] configuration section. The SKE used to use
958 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
959 is of course wrong. The official names that must be proposed in
960 the SKE are the ones defined in the protocol specification
961 (hmac-sha1-96 for example). The user can configure any hmac
962 using any hash function configured in the [hash] section. At
963 least, the mandatory must be configured.
965 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
967 * Added HMAC list to the SKE proposal list. It has now both
968 hash algorithm list and HMAC list. This makes the protocol
969 incompatible with previous versions. The SKE now seems to work
970 the way it is supposed to work, for the first time actually.
972 * Defined plain Hash algorithms to the protocol specification.
975 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Implemented support for key agreement packets into the server.
978 Added functions silc_server_key_agreement and
979 silc_server_send_key_agreement. Other than these functions,
980 server has nothing to do with this packet.
982 * Added support for private message key packets into the server.
983 Added functions silc_server_private_message_key and
984 silc_server_send_private_message_key.
988 * Changed the silc_[client|server]_protocol_ke_set_keys to be
989 called in the protocol's final callback instead in the END
990 protocol state. This makes a little more sense and in the same
991 time in client we can use the same protocol routines for normal
992 key exchange and to key agreement packet handling as well.
994 * Added to both client's and server's KE protocol context the
995 SilcSKEKeyMaterial pointer to save the key material. We will
996 bring the key material to the protocol's final callback by doing
997 this. The final callback must free the key material.
999 * Added SKE's packet_send callback into client's KE protocol
1000 context so that the caller can choose what packet sending function
1001 is used. This way we can use different packet sending when
1002 doing normal SKE when doing key agreement packet handling (in
1003 the key agreement packet handling we do not want to encrypt
1006 * Implemented the responder side of the key agreement routines
1007 in the client. The client can now bind to specified port and
1008 accept incoming key negotiation. The key material is passed
1009 to the application after the protocol is over.
1011 * Implemented the processing of incoming Key Agreement packet
1012 in the client. Added function silc_client_key_agreement to
1015 * Implemented the intiator side of the key agreement routines
1016 in the client. The client can now initiate key agreement with
1017 another remote client. The key material is passed to the
1018 application after the protocol is over.
1020 * Created client_keyagr.c to include all the key agreement
1023 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1024 SILC_TASK_CALLBACK except that it is not static.
1026 * Created client_notify.c and moved the Notify packet handling
1027 from the client.[ch] into that file.
1029 * Created client_prvmsg.c and moved all private message and
1030 private message key routines from the client.[ch] into that file.
1032 * Create client_channel.c and moved all channel message and
1033 channel private key routines from the client.[ch] into that file.
1035 * Changed silc_client_get_client_by_id_resolve to resolve with
1036 WHOIS command instead of IDENTIFY command, in the file
1037 lib/silclient/idlist.c.
1039 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Implemented the SKE's responder side to the Client library.
1043 * When FAILURE is received to the protocol do not trust it
1044 blindly. Register a timeout to wait whether the remote closes
1045 the connection as it should do it, only after that process the
1046 actual failure. This was changed to both client and server.
1048 * Added client_internal.h to include some of the structures
1049 there instead of client.h in lib/silcclient/.
1051 * Added function silc_task_unregister_by_callback to unregister
1052 timeouts by the callback function.
1054 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Some "Incomplete WHOIS info" errors has been appearing on the
1057 log files. Took away the entry->userinfo check from WHOIS
1058 reply sending. The entry->userinfo is now " " if client did not
1059 provide one. I thought this was fixed earlier but something
1060 is wrong still. Let's see if the error still appears.
1062 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Fixed a minor bug in the login when the channel key is
1065 re-generated in the server. It used to generate the key in
1066 wrong order and thus caused problems in the channel traffic.
1068 * Fixed a minor bug in channel key distsribution after
1069 KICK command. The key was not sent to the router even though
1072 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Added silc_ske_process_key_material_data as generic routine
1075 to process any key material as the SILC protocol dictates. The
1076 function is used by the actual SKE library but can be used by
1077 applications as well. This relates to the private message keys
1078 and the channel private keys since they must be processed the
1079 same way the normal SILC session keys. The protocol dictates
1080 this. Affected files: lib/silcske/silcske.[ch].
1082 Added also silc_ske_free_key_material to free the
1083 SilcSKEKeyMaterial structure.
1085 * Defined silc_cipher_set_key function to set the key for
1086 cipher without using the object's method function. The affected
1087 files: lib/silccrypt/silccipher.[ch].
1089 * Implemented silc silc_client_add_private_message_key,
1090 silc_client_add_private_message_key_ske,
1091 silc_client_del_private_message_key,
1092 silc_client_list_private_message_keys and
1093 silc_client_free_private_message_keys functions in the
1096 Added functions silc_client_send_private_message_key to send
1097 the Private Message Key payload and silc_client_private_message_key
1098 to handle incoming Private Message Key payload.
1100 * Added Cipher field to the Private Message Key payload to set
1101 the cipher to be used. If ignored, the default cipher defined
1102 in the SILC protocol (aes-256-cbc) is used.
1104 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * Removed lib/silcclient/ops.h file.
1108 Redefined parts of the SILC Client Library API. Created new
1109 file silcapi.h that deprecates the ops.h file and defines the
1110 published Client Library API. Defined also private message key
1111 API and channel private key API into the file.
1113 This is the file that the application must include from the
1114 SILC Client Library. Other files need not be included by
1115 the application anymore.
1117 * Added new key_agreement client operation callback and also
1118 defined the Key Agreement library API for the application.
1120 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1123 is used by clients to request key negotiation between another
1124 client in the SILC network. If the negotiation is started it
1125 is performed using the SKE protocol. The result of the
1126 negotiation, the secret key material, can be used for example
1127 as private message key.
1129 Implemented the Key Agreement payload into the files
1130 lib/silccore/silauth.[ch].
1132 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * Redefined ciphers for the SILC protocol. Added some new ciphers
1135 and defined the key lengths for the algorithms. Changed the
1136 code accordingly. The default key length is now 256 bits.
1138 * Fixed SKE key distribution function silc_ske_process_key_material
1139 when the key length is more than 128 bits. The default key
1140 length in SILC is now 256 bits.
1142 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1143 to indicate unsupported algorithm.
1145 * Renamed rijndael.c to aes.c and all functions as well.
1147 * Fixed a long standing channel key setting bug in client library.
1148 Weird that it has never surfaced before.
1150 * Fixed bug in channel deletion. If the entire channel is removed
1151 then it must also delete the references of the channel entry
1152 from the client's channel list as the client's channel entry and
1153 the channel's client entry share same memory.
1155 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Implemented CONNECT and SHUTDOWN commands in the client.
1159 * Implemented CLOSE command to the client.
1161 * Added the function silc_idlist_find_server_by_name into the
1162 files silcd/idlist.[ch].
1164 Added the function silc_idlist_find_server_by_conn into the
1165 files silcd/idlist.[ch].
1167 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * DIE command was renamed to SHUTDOWN. Updated the both code
1172 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1173 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1175 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1178 * Added function silc_server_create_connection function to create
1179 connection to remote router. My server implementation actually
1180 does not allow router to connect to normal server (it expects
1181 that normal server always initiates the connection to the router)
1182 so the CONNECT command is only good for connecting to another
1185 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1188 or some other client was kicked from the channel.
1190 Implemented the handling of the notify type to both client
1193 Implemented silc_server_send_notify_kicked to send the KICKED
1194 notify. It is used to send it to the server's primary router.
1196 * Implemented the KICK command into server and client.
1198 * Added `query' argument to the silc_idlist_get_client function
1199 to indicate whether to query the client from server or not if
1202 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1203 to indicate that the client is not channel founder.
1207 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Removed the rng context from SilcPacketContext structure and
1210 changed that the packet routine uses the Global RNG API.
1212 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Added support for quit message that client can "leave" on the
1215 channel when it quits the SILC. It is ditributed inside the
1216 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1218 Added silc_server_free_client_data that will take the
1219 signoff message as argument.
1221 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1223 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Updated parts of the protocol specification to keep it up
1228 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1231 payloads in one packet.
1233 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1234 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1235 use now the new List flag.
1237 * Also deprecated the following packet types: REPLACE_ID,
1238 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1240 * Added list support for Notify packet in server.
1242 * Added silc_server_send_notify_channel_change to send the
1243 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1244 the silc_server_send_replace_id.
1246 * Added silc_server_send_notify_nick_change to send the
1247 NICK_CHANGE notify type. Deprecates the function
1248 silc_server_send_replace_id.
1250 * Added silc_server_send_notify_join to send the JOIN notify type.
1251 Deprecates the function silc_server_send_new_channel_user.
1253 * Added silc_server_send_notify_leave to send LEAVE notify type.
1254 Deprecates the function silc_server_send_remove_channel_user.
1256 * Added silc_server_send_notify_cmode and
1257 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1258 types. Deprecates the silc_server_send_set_mode function.
1260 * Added SERVER_SIGNOFF notify type to indicate that server has
1261 quit. This means that all clients on the channel from that
1262 server will drop. This can be also used when netsplit happens.
1264 Deprecated REMOVE_ID packet type since it is not needed anymore
1267 Added silc_server_send_notify_server_signoff to send the
1268 SERVER_SIGNOFF notify type. Deprecates the function
1269 silc_server_send_remove_id.
1271 Added also silc_server_send_notify_signoff to send the
1272 SIGNOFF notify type.
1274 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1275 SILC protocol from this day on. Changed the protocol
1276 specification as well.
1278 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1279 notify type. It is used between routers to notify about
1280 topic changes on a channel.
1282 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1285 * Partly updated the protocol specification to comply with the
1286 changes now made. It is still though a bit outdated.
1288 * The JOIN notify type now takes one extra argument <Channel ID>.
1289 The packet used to be destined to the channel but now the
1290 JOIN type may be sent as list thus it is impossible to
1291 destine it to any specific channel. By adding this argument
1292 it is again possible.
1294 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Added CREDITS file. The CHANGES and CREDITS file will appear
1297 in the distribution as well.
1299 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1302 types in the server's silcd/packet_receive.c.
1304 * Implemented CMODE and CUMODE to work in router environment.
1306 * Fixed minor encoding and decoding buglet from the
1307 lib/silccore/silcmode.c.
1309 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1312 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1314 * Changed all SilcConfigServer* and silc_config_server* to
1315 SilcServerConfig* and silc_server_config*, respectively.
1318 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Associated the ID (client or server ID) to the Authentication
1321 Payload to avoid any possibility of forging. Updated the
1322 protocol specification and the code accordingly.
1324 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * The RSA key length is now save to the RsaKey context in the
1327 key generation process in lib/silccrypt/rsa.c. The key length
1328 is now used to figure out the maximum size of the block allowed
1329 to be encrypted/signed.
1331 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1332 is equivalent to the silc_mp_mp2bin but does not allocate any
1335 * Changed silc_mp_mp2bin API to take length argument. If it is
1336 non-zero then the buffer is allocated that large. If zero, then
1337 the size is approximated using silc_mp_sizeinbase, which however
1340 * Created Global RNG API which is global RNG that application can
1341 initialize. After initializing, any routine anywhere in the
1342 code (including library) can use RNG without allocating a new
1343 RNG object. This was done to allow this sort of use of the
1344 RNG in code that has no chance to allocate RNG object. All
1345 applications currently allocate this and many routines in the
1346 library use this. Affected file lib/silccrypt/silcrng.[ch].
1348 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1349 it to use the Global RNG API.
1351 * Defined Authentication Payload into protocol specification that
1352 is used during SILC session to authenticate entities. It is
1353 used for example by client to authenticate itself to the server
1354 to obtain server operator privileges.
1356 Implemented this payload into the lib/silccore/silcauth.[ch].
1357 Implemented also routines for public key based authentication
1358 as the new protocol specification dictates.
1360 Moved definitions of different authentication methods from
1361 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1363 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1364 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1365 silc_pkcs_verify_with_hash functions into the file
1366 lib/silccrypt/silcpkcs.[ch].
1368 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * The client entry's userinfo pointer must be always valid.
1371 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1372 will fail since it requires the userinfo. Now, the userinfo
1373 is allocated as "" if actual userinfo does not exist. Actually,
1374 it must exist and it is totally Ok to drop client connections
1375 that does not announce the userinfo. However, we will make
1376 this workaround for now.
1378 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1379 to return the remote port by socket.
1381 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1384 SILC_SERVER_PENDING_EXEC and added an new macro
1385 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1386 data or when error occurs while processing the pending command.
1388 Added new argument `destructor' into silc_server_command_pending
1389 and to the SilcServerCommandPending object. This destructor is
1390 now called after calling the pending callback or if error occurs
1391 immediately. If error occurs the actual pending callback won't
1392 be called at all - only the destructor. The destructor may be
1393 NULL if destructor is not needed.
1395 All this applies for client library code as well. Similar
1396 changes were made there as well for the pending commands.
1398 In the client, the application must now allocate the
1399 SilcClientCommandContext with the silc_client_command_alloc
1402 * Added reference counter to the SilcServerCommandContext. Added
1403 function silc_server_command_alloc and silc_server_command_dup
1406 Same type of functions added to the client library for the same
1409 * Removed the cmd_ident from IDListData away since it is now
1410 global for all connections. It is the command identifier used
1411 in command sending and with pending commands. The affected file
1414 * Added reference counter to the SilcSocketConnection objecet to
1415 indicate the usage count of the object. The object won't be
1416 freed untill the reference counter hits zero. Currently only
1417 server uses this, and client ignores it. The client must be
1418 set to use this too later. The affected files are
1419 lib/silccore/silcsockconn.[ch]. Added also the function
1420 silc_socket_dup to increase the reference counter.
1422 This was mainly added because it is possible that the socket
1423 is removed underneath of pending command or other async
1424 operation. Now it won't be free'd and proper DISCONNECTING
1425 flags, etc. can be set to avoid sending data to connection that
1426 is not valid anymore.
1428 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1429 the connection. After that it sets SILC_SET_DISCONNECTED.
1430 It is, however, possible that the socket data is not still freed.
1431 The silc_server_packet_process now checks that data is not
1432 read or written to connection that is DISCONNECTED. The socket
1433 get's freed when the reference counter hits zero.
1435 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Changed the client operation API: channel_message operation's
1438 `sender' is now the client entry of the sender, not the nickname
1439 and the `channel' is the channel entry, not the channel name.
1441 In the private_message operation the `sender' is now also the
1442 client entry of the sender not the nickname.
1444 Affected file is lib/silcclient/ops.h and all applications
1445 using the client operations.
1447 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Moved the calling of ops->connect() from connect_to_server_final
1450 into receive_new_id functin since that is the point when the
1451 client is actually allowed to send traffic to network. The
1452 affected file is lib/silcclient/client.c.
1454 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1456 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1457 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1458 (if needs broadcasting) instead of broadcasting the packets one
1459 by one which would make a burst in the network traffic.
1461 * Added `broadcast' argument to the functions in silcd/server.[ch]
1462 silc_server_create_new_channel[_with_id] to indicate whether
1463 to send New Channel packet to primary router.
1465 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Added new function into the silcd/server.[ch] files:
1468 silc_server_create_new_channel_with_id to create new channel with
1469 already existing Channel ID.
1471 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1472 lib/silccore/silcpacket.h. This packet is used t send list of
1473 Set Mode payloads inside one packet. Server uses this to set
1474 the modes for the channels and clients on those channels, that it
1475 announced to the router when it connected to it. The protocol
1476 specification has been updated accordingly.
1478 * The silc_server_new_channel did not handle the packet coming
1479 from normal server as it normally does not send that. However,
1480 when it announces its channels it does send it. Implemented
1481 the support for that.
1483 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1484 into the file lib/silccore/id.h.
1486 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Fixed memory leaks in the functions silc_idlist_del_client,
1489 silc_idlist_del_channel and silc_idlist_del_server in the file
1490 silcd/idlist.c. All of those leaked like a sieve.
1492 * Fixed some small memory leaks in the client's function
1493 silc_client_notify_by_server.
1495 * Added functions into silcd/server.c: silc_server_announce_clients,
1496 silc_server_announce_channels and silc_server_announce_server.
1497 These functions are used by normal and router server to announce
1498 to its primary router about clients, channels and servers (when
1499 router) that we own. This is done after we've connected to the
1502 These functions effectively implements the following packet types:
1503 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1504 and SILC_PACKET_NEW_ID_LIST.
1506 * Added new functions into the silcd/packet_receive.[ch]:
1507 silc_server_new_id_list, silc_server_new_channel_list and
1508 silc_server_new_channel_user_list to handle the incoming
1509 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1511 * Added support of changing Channel ID in the function
1512 silc_server_replace_id. If the server that announces a channel
1513 to the router already exists in the router (with same name but
1514 with different Channel ID), router is responsible to send
1515 Replace ID packet to the server and force the server to change
1516 the Channel ID to the one router has.
1518 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1519 client that the Channel ID has been changed by the router. The
1520 normal server sends this to the client. Client must start using
1521 the new Channel ID as the channel's ID.
1523 Implemented handling of this new type into lib/silcclient/client.c
1524 into the function silc_client_notify_by_server.
1526 * Added new function silc_idlist_replace_channel_id into the files
1527 silcd/idlist.[ch] to replace the Channel ID.
1529 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Call silc_server_command_identify_check always when processing
1532 the IDENTIFY command in silcd/command.c
1534 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1537 send keepalive packets. The packet can be sent by clients,
1538 servers and routers.
1540 Added function silc_socket_set_heartbeat into the file
1541 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1542 If not set, the heartbeat is not performed. The actual
1543 heartbeat is implemented in the low level socket connection
1544 library. However, application is responsible of actually
1547 Added silc_server_send_heartbeat to send the actual heartbeat
1548 packet into silcd/packet_send.[ch]. Server now performs
1549 keepalive with all connections.
1551 * Added silc_task_get_first function into lib/silcutil/silctask.c
1552 to return the timeout task with shortest timeout. There was a bug
1553 in task unregistration that caused problems. TODO has been
1554 updated to include that task system must be rewritten.
1556 * The client library will now resolve the client information when
1557 receiving JOIN notify from server for client that we know but
1558 have incomplete information.
1560 * Rewrote parts of silc_server_remove_from_channels and
1561 silc_server_remove_from_one_channel as they did not remove the
1562 channel in some circumstances even though they should've.
1564 * Encryption problem encountered in server:
1566 The LEAVE command used to send the Channel Key packet to the
1567 router immediately after generating it. However, the code
1568 had earlier sent Remove Channel user packet but not immediately,
1569 ie. it was put to queue. The order of packets in the router
1570 was that Channel Key packet was first and Remove Channel User
1571 packet was second, even though they were encrypted in the
1572 reverse order. For this reason, MAC check failed. Now, this
1573 is fixed by not sending the Channel Key packet immediately but
1574 putting it to queue. However, this is more fundamental problem:
1575 packets that are in queue should actually not be encrypted
1576 because packets that are sent immediately gets encrypted
1577 actually with wrong IV (and thus MAC check fails). So, packets
1578 that are in queue should be encrypted when they are sent to
1579 the wire and not when they put to the queue.
1581 However, the problem is that the current system has not been
1582 designed to work that way. Instead, the packet is encrypted
1583 as soon as possible and left to the queue. The queue is then
1584 just purged into wire. There won't be any fixes for this
1585 any time soon. So, the current semantic for packet sending
1588 o If you send packet to remote host and do not force the send
1589 (the packet will be in queue) then all subsequent packets to the
1590 same remote host must also be put to the queue. Only after the
1591 queue has been purged is it safe again to force the packet
1594 o If you send all packets immediately then it safe to send
1595 any of subsequent packets through the queue, however, after
1596 the first packet is put to queue then any subsequent packets
1597 must also be put to the queue.
1599 Follow these rules and everything works fine.
1601 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Added new function silc_server_remove_clients_by_server to
1604 remove all client entries from ID list when the server connection
1605 is lost. In this case it is also important to invalidate all
1606 client entires as they hold the invalid server entry. This
1607 fixes fatal bug when server has lost connection and will reconnect
1610 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Made some sanity checks to silc_server_daemonise like to check
1613 whether the requested user and group actually exists.
1615 * Added sanity check to SKE's silc_ske_responder_finish to check
1616 that the public and private key actually is valid.
1618 * Invalidate the client's nickname when receiving Replace ID
1619 packet and the Client ID is being replaced. This means that the
1620 server will query the nickname if someone needs it (client)
1623 * Sort the ID Cache in client library when the ID Cache data
1624 has changed (needs sorting).
1626 * Do not allow for SILC client to create several connections to
1627 several servers. The client does not support windows right now
1628 and generating multiple connections causes weird behaviour.
1630 Irssi-silc client does support windows and can handle several
1631 connections without problems, see: www.irssi.org and SILC plugin.
1633 * Fixed some places where client was added to the IDList. The
1634 rule of thumb is following (in order to get everything right):
1635 If the client is directly connected local client then the
1636 `connection' argument must be set and `router' argument must be
1637 NULL to silc_idlist_add_client function. If the client is not
1638 directly connected client then the `router' argument must
1639 bet set and the `connection' argument must be NULL to the
1640 silc_idlist_add_client function.
1642 * The funtion silc_server_packet_send_local_channel actually did
1643 not check whether the client was locally connected or not. It
1644 does that now. Fixed a bug related to LEAVE command.
1646 * Fixed Remove Channel User payload parsing bug in server's
1647 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1649 * The server's silc_server_save_channel_key now checks also the
1650 global ID list for the channel as it might not be in the local
1651 list. Fixed a bug related to LEAVE command.
1653 * Is this the end of the [<unknown>] buglet that has been lurking
1654 around for a long time? A little for loop fix in server's
1655 silc_server_command_whois_parse that is used by both IDENTIFY
1656 and WHOIS command. At least, this was a clear bug and a cause
1657 of one type of [<unknown>] buglet.
1659 * WHOIS and IDENTIFY commands call the function
1660 silc_server_command_[whois/identify]_check function even if
1661 we are not router server.
1663 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Added --with-gmp configuration option. If set the GMP
1666 is always compiled in the SILC source tree. If not set then
1667 it is checked whether the system has the GMP3 installed. If
1668 it has then the GMP won't be compiled (the system's headers
1669 and library is used), if it doesn't have it then the GMP is
1670 compiled in the SILC source tree.
1672 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Changed RSA private exponent generation to what PKCS #1
1675 suggests. We try to find the smallest possible d by doing
1676 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1677 not security fix but optimization.
1679 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Added new config entry [Identity] to fork the server and run
1682 it as specific user and group. A patch from Bostik.
1684 * Imported Dotconf configuration library into lib/dotconf.
1685 This will be used to create the SILC configuration files later.
1686 It will appear in the distsribution after this commit.
1688 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * A big code auditing weekend happening. Auditing code for
1691 obvious mistakes, bugs and errors. Also, removing any code
1694 Removed files for being obsolete:
1696 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1697 inline in the file lib/silcutil/silcbuffer.h)
1699 o lib/silcutil/silcbufutil.c (the header has inline versions)
1701 Changed code to fix possible error conditions:
1703 o The buffer formatting routines now check that the destination
1704 buffer really has enough space to add the data. This applies for
1705 both buffer formatting and unformatting
1706 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1707 unformatting was changed to accomodate following rules:
1708 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1709 sent to the function while XXX_*STRING will not allocate or copy
1710 the data into the buffer. Instead it sets the pointer from the
1711 buffer into the pointer sent as argument (XXX_*STRING used to
1712 require that the pointer must be allocated already). This change
1713 makes this whole thing a bit more consistent and more optimized
1714 (note that the data returned in the unformatting with XXX_*STRING
1715 must not be freed now). The routines return now -1 on error.
1717 o Tried to find all code that use buffer_format and buffer_unformat
1718 and added return value checking to prevent formatting and
1719 especially unformatting errors and possible subsequent fatal
1722 o Changed ske->x and ske->KEY to mallocated pointers in
1723 lib/silcske/silcske.h. Fixed possible data and memory leak.
1725 o Added return value checking to all *_parse* functions. Fixed
1726 many memory leaks as well.
1728 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1729 so that buffer overflows would not happen. All code now also
1730 checks the return value as it can fail.
1732 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Added reconnection support to server if the normal server looses
1735 its connection to the router (for example if router is rebooted).
1736 The server performs normal reconnection strategy implemented
1737 to the server. Affected file silcd/server.c.
1739 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Added new packet type SILC_PACKET_SET_MODE that is used to
1742 distribute the information about changed modes (for clients,
1743 channels and clients channel modes) to all routers in the
1744 network. Updated the protocol specification accordingly.
1746 Added functions into silcd/packet_send.c and
1747 silcd/packet_receive.c: silc_server_send_set_mode,
1748 silc_server_set_mode.
1750 Added new files silcmode.[ch] into lib/silccore that implements
1751 the encoding and decoding of Set Mode Payload. Added new type
1752 SilcSetModePayload. Moved the definitions of different modes
1753 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1755 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Oops, a little mistake in server's connection authentication
1758 protocol. The protocol is not ended with FAILURE but with
1759 SUCCESS if the authentication is Ok. :) Affected file is
1762 * Implemented NICK_CHANGE notify handling in server in the file
1763 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1764 the local clients on the channel. After the changing nickname
1765 in router environment snhould work and the [<unknown>] nickname
1766 should appear no more.
1768 The silc_server_replace_id function that receives the Replace ID
1769 payload now sends the NICK_CHANGE notify type also in the file
1770 silcd/packet_receive.c
1772 * Changed WHOIS and IDENTIFY command to support the maximum amount
1773 of arguments defined in protocol specs (3328 arguments). This
1774 fixed a bug that caused problems when there were more than three
1777 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Added extra parameter, command identifier, to the
1780 silc_client_send_command so that explicit command identifier
1783 Changed that ID list routines uses specific command identifier
1784 when sending WHOIS/IDENTIFY requests to the server so that they
1785 can be identified when the reply comes back.
1787 Affected files lib/silcclient/command.[ch],
1788 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1790 * Added `sender' argument to silc_server_packet_send_to_channel
1791 to indicaet the sender who originally sent the packet to us
1792 that we are now re-sending. Ignored if NULL. Affected file
1793 silcd/packet_send.[ch].
1795 * Added some server statistics support in silcd/server_internal.h
1796 SilcServerStatistics structure and around the server code. Also
1797 send some nice statistics information when client is connecting
1800 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Fixed channel ID decoding in server's JOIN command reply in
1803 silcd/command_reply.c
1805 * Fixed braodcasting of replace ID payload to not to send it if
1806 we are standalone server in silcd/packet_receive.c.
1808 * Fixed all channel message sending routines to not to send
1809 packets to clients that has router set, since they are routed
1810 separately in the same function earlier. Affects file
1811 silcd/packet_send.c and all channel packet sending functions.
1813 * In USERS reply, res_argv[i] are not allocated, the table
1814 is allocated. Thus changed that free the table, not its
1817 * In server's whois_check and identify_check if the client is
1818 locally connected do not send any WHOIS commands - they are not
1821 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * Fixed some minor bugs in client when sending WHOIS command. The
1824 arguments was in wrong order.
1826 * Removed statis function add_to_channel from server in
1827 silcd/command.c that was previously used with the joining but
1830 * Tested USERS command in router environment successfully with two
1831 routers, two servers and two clients.
1833 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Reorganized the USERS command and command reply in client library
1836 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1837 When the command is given by user we register a pending command
1838 callback that will reprocess the command after the reply has been
1839 received from the server. When reprocessing the packet we then
1840 display the information. Thus, the USERS information is displayed
1841 now in the command callback instead of in the command reply
1842 callback. The processing of the command is same as previously
1843 when server has sent the command reply in the JOINing process.
1845 * Added to USERS command in silcd/command_reply.c to join the client,
1846 we didn't use to know about, to the channel after we've created
1847 a client entry for it. Also, for clienet we did know already still
1848 check whether it is on the channel or not and add it if not.
1850 * Removed silc_server_command_join_notify as the function and its
1853 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Changed the client's pending command handling to the same as the
1856 server's pending command handling. It is also now possible to
1857 execute command reply functions from other command reply
1858 function as the function callbacks for commands and command
1859 replies are one and same. The pending commands are not static
1860 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1861 in client connection context. Thus, pending commands are server
1862 connection specific as it is convenient.
1864 Changed the function silc_client_command_pending and
1865 silc_client_command_pending_del and added new function
1866 silc_client_command_pending_check. Removed the
1867 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1870 * Added cmd_ident, current command identifier, to the client
1871 connection context in lib/silcclient/client.h to keep track on
1872 command identifiers used in command sending. Client's command reply
1873 function handling now supports the mandatory command identifiers.
1875 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1876 funtions in client to fully support pending command callbacks.
1878 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1879 as one of the arguments to the application in the command reply
1882 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1883 before first releasing SILC but came back. Now it is removed again
1884 and should come back nomore. The FORWARDED flag was used only
1885 by the JOINing procedure by forwarding the command packet to router.
1886 Now, the JOINing procedure has been changed to more generic (due
1887 to various router environment issues) and FORWARDED is not needed
1888 anymore for anything. The protocol specification is yet to be
1891 Now, removed silc_server_packet_forward from server and the flag
1892 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1894 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Renamed NAMES command to USERS command. The NAMES was named that
1897 due to historical reasons. Now it is renamed. Also, rewrote
1898 parts of the USERS command. The nickname list is not sent anymore
1899 by the server. Only Client ID and mode lists are sent in the USERS
1900 command. Changed this also to the protocol specification.
1902 The client now resolves the names and stuff after it receives
1903 the USERS list from the server when joining to the channel.
1905 * WHOIS and IDENTIFY commands has been changed to support multiple
1906 Client ID's per command. One can now search for multiple users
1907 in the network by sending only one WHOIS or IDENTIFY command.
1908 Changed the code and the protocol specifications.
1910 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1911 uses silc_server_command_whois_parse to parse the request. */
1913 * If normal server, do not parse the WHOIS and IDENTIFY requests
1914 before sending it to the router. Saves some time.
1916 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Fixed JOIN command on client library. Wrong number of arguments
1919 used to crash the client.
1921 * Added silc_server_channel_has_global function to check whether
1922 channel has global users or not.
1924 * Added silc_server_channel_has_local function to check whether channel
1925 has locally connected clients on the channel.
1927 * The silc_server_remove_from_one_channel now checks whether the
1928 channel has global users or not after given client was removed from
1929 the channel. It also checks whether the channel has local clients
1930 on the channel anymore. If it does not have then the channel entry
1931 is removed as it is not needed anymore.
1933 * The silc_server_notify now checks on JOIN notify whether the joining
1934 client is one of locally connected or global. If it is global then
1935 the channel has now global users on the channel and that is marked
1936 to the channel entry. Also, it now saves the global client to
1937 global list who is joining and JOINs it to the channel. This is
1938 for normal server, that is.
1940 Changed silc_server_send_notify_on_channel,
1941 silc_server_packet_relay_to_channel and
1942 silc_server_packet_send_to_channel check if we are normal server
1943 and client has router set (ie. global client) do not send the
1944 message to that client, as it is already routed to our router.
1946 * Implemented LEAVE notify type handling in silc_server_notify
1949 * Tested LEAVE command in router environment successfully. Tested
1950 with two routers, two servers and two clients.
1954 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1956 * Implemented SIGNOFF notify type handling in silc_server_notify
1959 * silc_server_remove_id now removes the client entry from all channels
1960 it has joined and thusly sends SIGNOFF notify type.
1962 * Rewrote the NAMES list generation in server by removing two excess
1963 loops. The lists are created now inside one loop.
1965 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * silc_server_remove_channel_user checks now also global list
1968 for channel and client.
1970 * silc_server_new_channel_user checks now both local and global
1971 list for channel and client. Fixed a bug in client id decoding.
1972 Used to decode wrong buffer.
1974 * silc_server_channel_message checks now both local and global
1975 list for channel entry.
1977 * Tested channel joining (hence JOIN) in router environment
1978 successfully. Tested with two routers, two servers and two
1981 * Tested channel message sending in router environment successfully.
1983 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added silc_server_save_channel_key into server.[ch] to save the
1986 received channel key in Channel Key payload processing. It is
1987 also used in JOIN command reply handling.
1989 Equivalent function silc_client_save_channel_key added into
1990 client.[ch] into client library.
1992 * Changed JOIN command reply to send information whether the channel
1993 was created or not (is existing already) and the channel key
1994 payload. Changed protocol specs accordingly.
1996 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1997 the request was sent by ID and not by nickname. Crashed on
2000 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2003 now correctly save the received data.
2005 * silc_server_free_sock_user_data now notifies routers in the
2006 network about entities leaving the network.
2008 At the same time implemented functions silc_server_remove_id
2009 and silc_server_send_remove_id to receive and send REMOVE_ID
2010 packets. The packet is used to notify routers in the network
2011 about leaving entities. The ID removed will become invalid in
2014 * Added function silc_idlist_del_server into server. Removes and
2015 free's server entry from ID list.
2017 * silc_server_private_message function now checks, if we are router,
2018 that the destination ID really is valid ID, naturally.
2020 * In router when NEW_ID packet is received (for new client) the
2021 hash of the Client ID is saved in the ID Cache but the
2022 client->nickname is set to NULL, instead of putting the hash
2025 IDENTIFY command now also checks that client->nickname must be
2026 valid. If it is not if will request the data from the server who
2027 owns the client. Added new function
2028 silc_server_command_identify_check.
2030 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2031 to set the command to already allocated Command Payload.
2033 * Tested private message sending in router environment with two
2034 routers, two servers and two clients. Fixed minor bugs and now
2037 * Fixed segfault from client's NAMES command. Used to crash if
2040 * Forwarded packets must not be routed even if it is not destined
2041 to the receiver. Changed server code comply with this.
2043 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Added `require_reverse_mapping' boolean value to ServerParams
2046 structure. If TRUE (not default) the server will require that
2047 the connecting host has fully qualified domain name.
2049 If the reverse mapping is not required and hostname could not be
2050 found the IP address is used as hostname.
2052 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Implemented version string checking to both client and server.
2055 The check is incomplete currently due to the abnormal version
2056 strings used in development version of SILC.
2058 * Changed all command functions in server to use the new
2061 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Changed char *data to unsigned char *data in ID Cache system to
2064 support binary data as ID Cache data. Changed code to support
2065 binary data in lib/silccore/idcache.c.
2067 * Renamed silc_server_packet_relay_command_reply to
2068 silc_server_command_reply as it is normal packet receiving
2069 function. Rewrote the function to accept command replys for
2070 servers and not only for clients.
2072 * Mark remote router always as registered server if we are connecting
2073 to it. Otherwise, commands sent by the router to us are ignored.
2075 * All ID List find routines now returns the ID Cache Entry pointer
2076 as well if requested.
2078 * WHOIS command works now in router environment, tested with two
2079 routers, two servers and two clients.
2081 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2082 in router environment (as it is almost equivalent to WHOIS) but
2083 hasn't been tested thoroughly. Added new functions:
2085 silc_server_command_identify_parse
2086 silc_server_command_identify_send_reply
2087 silc_server_command_identify_from_client
2088 silc_server_command_identify_from_server
2090 * Disabled route cache adding because adding two different ID's with
2091 same IP replaces the old cache entry thus giving wrong route.
2092 The entry->router->connection is always the fastest route anyway
2093 so route cache may not be needed. Of course, new routes maybe
2094 established after receiving the ID when the entry->router->connection
2095 might not be anymore the most optimal.
2097 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Add route cache for received ID for fast routing.
2101 * Added silc_server_packet_route to route received packet on router
2102 that is not destined to us.
2104 * Renamed silc_server_get_route to silc_server_route_get.
2106 * Added id_string and id_string_len fields into SilcServer to
2107 include encoded ServerID for fast comparing without excess
2108 encoding of the ID's.
2110 * Cleaned up WHOIS command on server side. Added following static
2113 silc_server_command_whois_parse
2114 silc_server_command_whois_check
2115 silc_server_command_whois_send_reply
2116 silc_server_command_whois_from_client
2117 silc_server_command_whois_from_server
2119 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2120 arguments in command replies. All command functions should be
2121 updated to use this macro.
2123 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Minor typo fixes on command reply handling on server.
2127 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Added silc_server_command_add_to_channel internal routine to add
2130 the client to the channel after router has created the channel and
2131 sent command reply to the server.
2133 * Added generic silc_server_send_command to send any command from
2136 * Use static buffer with ID rendering instead of duplicating data.
2138 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Fixed a channel user mode bug when joining to a channel server gave
2141 everybody channel founder rights, oops.
2143 * We mark ourselves as the router of the incoming server connection
2144 if we are router ourselves. This way we can check in some packet
2145 sending functions whether it is locally connected server. For
2146 incoming router connections we put NULL.
2148 * For router sending packets locally means now always sending the
2149 packet cell wide; to local clients and local servers. For normal
2150 server sending packet locally means sending it to only local
2153 * Fixed the JOIN command to really work in router environment. If the
2154 channel is created it is always created by the router. Router is
2155 also responsible of making the initial joining to the channel,
2156 sending JOIN notify to the sending server and distributing
2157 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2158 does not exist server doesn't do anything else but forward the
2159 command to the router which performs everything.
2161 * Added silc_server_send_channel_key function to send the Channel Key
2164 * Added silc_server_create_channel_key to create new channel key. The
2165 channel key is now re-generated everytime someone joins or leaves
2166 a channel, as protocol dictates. Note: channel->key_len is the
2169 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2172 packet_receive.[ch] to separate packet sending and receiving
2173 routines. The server.[ch] now includes everything else including
2174 actual packet processing (writing and reading data) and other
2177 Renamed silc_server_private_message_send_internal to
2178 silc_server_send_private_message. The routine is still though
2179 used only to relay private messages as server does not send
2180 private messages itself.
2182 Renamed silc_server_new_channel to silc_server_create_new_channel
2183 and added new function sicl_server_new_channel that handles the
2184 incoming New Channel packet. Added also new sending function
2185 silc_server_send_new_channel to send New Channel Payload.
2187 * Added new function silc_server_notify to process incoming notify
2188 packet to the server/router. Server may then relay the notify
2189 to clients if needed.
2191 * Added new function silc_server_new_channel_user to process incoming
2192 New Channel User packet. Router will redistribute the packet and
2193 send JOIN notify to its local clients and locally connected servers
2194 if needed. Normal server will send JOIN notify to its local client
2195 on same channel when received this packet. Added also corresponding
2196 sending function silc_server_send_new_channel_user to sent the
2199 * Added boolean route argument to send_notif_to_channel and
2200 packet_send_to_channel functions to attempt to route the packet
2201 if it is TRUE and send only locally if it is FALSE.
2203 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * silc_server_replace_id now broadcasts the received replace ID
2206 packet if it is not broadcast packet already. The router must
2207 broadcast to inform other routers about changed ID.
2209 * Added backpointer to server's router into SilcServer context in
2210 silcd/server_internal.h.
2212 * Fixed silc_server_packet_broadcast to send correct broadcast
2215 * The channel key is now distributed to the local client as soon
2216 as it is received from the router (in router environment) so that
2217 no other packet may be sent for the channel until client has
2220 * silc_server_remove_channel_user now broadcasts the received
2221 Remove Channel User packet if it is not broadcast packet already.
2222 The router must broadcast to inform other routers about removed
2225 * Added users field into SilcPacketContext that is a reference count
2226 of the context. One can increase the reference count by calling
2227 silc_packet_context_dup which is now changed to just increase the
2228 reference count instead of duplicating the data. The reference
2229 count is decresed by calling silc_packet_context_free that will
2230 free the data after the reference count hits zero.
2232 For now on the packet context and everything allocated into it
2233 (including the raw packet from network) must be freed by calling
2234 the new silc_packet_context_free function. Added also new function
2235 silc_packet_context_alloc that must be used now to allocate the
2236 context. This also means that if a routine is asynchronous from
2237 silc_[client/server]_packet_parse_type the packet context must
2238 be duplicated by calling silc_packet_context_dup. Otherwise it
2239 gets free'd after silc_[client/server]_packet_parse_type returns.
2240 Also, one must remember that if packet is duplicated then its
2241 reference count must be decresed by calling the free function as
2242 many times as it was duplicated.
2244 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2245 from both client and server.
2247 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Made joining to a channel working in router environment.
2251 * Cleaned up JOIN command on server side and create function
2252 silc_server_command_join_channel internal routine to make the
2255 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Changed silc_command_pending list to SilcDList. Also, added
2258 `ident' field to SilcServerCommandPending structure to identify
2259 the reply and to call correct callback.
2261 Added silc_server_command_pending_check function to replace the
2262 corresnponding macro. The silc_command_pending list is not
2265 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2266 to set identifier to previously allocated Command Payload. It
2267 is used to set identifier for command when resending Command
2270 * Added silc_command_payload_encode_payload to encode Command
2271 Payload buffer from SilcCommandPayload structure.
2273 * Added silc_argument_payload_encode_payload to encode Argument
2274 payload buffer from SilcArgumentPayload structure.
2276 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Changed WHOIS command to support router connection on server side.
2279 The whois request is always sent to router unless the server is
2280 standalone server. After server has received the reply from the
2281 router will it send the reply to the client.
2283 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2284 broadcast received broadcast packet. The function is used only
2285 by router. The broadcast packet is always sent to the router's
2288 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2289 render given ID to printable string, for log files for example.
2291 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Made basic router to router connections working. At least they
2294 can now connect to each other but nothing really works the way
2295 they are supposed - yet.
2297 * Added new initiator token to RouterConnection configuration
2298 file in silcd/serverconfig.[ch]. It is used to tell whether we
2299 are the initiator to the remote router or whether we'll expect
2300 the other end to connect.
2302 * Moved registering of listener task to silc_server_init, hence
2303 the server starts listenning as soon as it is run, even if it
2304 does not have connections to other routers. Let's see how well
2307 * Changed default connection retry timeouts for more suitable in
2310 * Removed cipher and such arguments from silc_idlist_add_client
2311 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2312 Added new function silc_idlist_add_data to add the keys and stuff
2315 * Added SilcIDListData structure and added it to SilcClientEntry
2316 and SilcServerEntry as their first field in the structure. This
2317 way we can explicitly cast the ID entries to the SilcIDListData
2318 structure and get common data for the entries. In past, we had
2319 to first check what type of connection it is and then cast it to
2320 correct ID entry type. Now, we can directly cast the opaque
2321 pointer to the SilcIDListData (no matter what ID entry it actually
2322 is) and get the data needed.
2324 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2327 in some circumstances even if threre were timeout tasks, though not
2328 IO tasks, but tasks anyway. Now fixed.
2330 * Defined SilcServerConnection structure to hold connection specific
2331 stuff about directly connected servers and routers. The definition
2332 is currently in silcd/server_internal.h. I thought about having
2333 a bit more important role fro this struct but for now it is used
2334 only when connecting to other server (or router actually).
2336 * Added connecting retry support in server when connecting to
2337 router(s). The retry feature implement exponential backoff
2338 algorithm. Also, added SilcServerParams structure to hold default
2339 parameters for server. For now, it include these retry settings
2340 and are hard coded. After server is moded to be as Silc Server
2341 Library this structure will be more important.
2343 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Changed client librarys channel->clients table to SilcList and
2346 changed code accordingly.
2348 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Changed client's channel table to SilcList and changed code
2351 accordingly. Also changed SilcChannelClientEntry to include back-
2352 pointer to the channel so that client entry can use that structure
2353 as list as well and we have fast cross-reference to the channel.
2354 This change dramatically decreased the complexity of channel
2355 handling with client entry and vice versa (removed one extra
2356 loop when searching for channel entry from many functions).
2358 * Changed server->sim from table to SilcDList and changed code
2361 * NAMES command can now be used from user interface. It will show
2362 the user list on the channel, neatly.
2364 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2365 Code now saves realname of the user if it becomes available.
2367 * Renamed configure.in to configure.in.pre and made ./prepare
2368 script to automatically add correct version string to
2369 configure.in which it creates from configure.in.pre.
2371 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * NAMES command reply now shows users mode with the nickname when
2376 * Moved silc_client_ch[u]mode[_char] functions from
2377 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2378 place sucks, they are utility functions and should be in some
2381 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2383 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2386 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Added TRQ (efficient deque and list library) into lib/trq. This is
2391 a very good list library that is currently used in the SILC. Defined
2392 SilcList API over the library because I didn't like the API very
2393 much. See lib/trq/silclist.h for the API and examples of how to
2394 use the API. Fixed various places in the code to use the new
2395 SilcList API. The SilcList is meant for lists that has a structure
2396 already defined as a list. It is not suitable to add just some
2397 context to the list (in TRQ, the context is the list actually).
2399 So, I defined SilcDList that can be used for the purpose where
2400 predefined list structure does not exit. This can be used as
2401 such list. Now some context just can be added to the SilcDList.
2402 Currently this list is not used in the SILC just yet, though there
2403 are a lot places where this can replace dynamically allocated
2404 tables and I will fix these places, later, to use SilcDList.
2405 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2406 and use TRQ internally).
2408 Also fixed some annoying warning messages that the original TRQ
2409 code generated. Also minor changes to TRQ's Makefile.in.
2411 * Added support for querying by Client ID to both WHOIS and
2412 IDENTIFY commands into server, as required by the protocol.
2414 * Removed method function pointers from SilcBuffer structure. They
2415 weren't used to anything and just increased the context size for
2416 no good reason. This change also made silc_buffer_alloc and
2417 silc_buffer_free functions inline functions.
2419 * Disabled command flooding detection support until it's fixed so
2420 that it accepts commands in but does not execute them more than once
2423 * Added silc_net_localhost(), to return local hostname, into
2424 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2425 that must be initialized before calling silc_client_init.
2427 * Added new function: silc_server_send_notify_on_channels to send
2428 notify messages to all channels client has joined. It is assured
2429 that the message is sent only once per client.
2431 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2432 lib/silcutil/silcutil.[ch] as silc_format function. The new
2433 function is generic and is used by server as well, not only by
2434 the logging routines.
2436 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2437 the provided version string was not acceptable. Added new function:
2438 silc_ske_check_version into lib/silcske/silcske.h. The function
2439 must be implemented by the application (client or server) and it
2440 does not reside in the SKE library. The function checks the version
2441 string remote end sent.
2443 * Added back pointers (to opaque context and to SilcSocketConnection)
2444 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2446 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2447 duplicate packet context structure.
2449 * Changed `notify' client operation to send same arguments as client
2450 receives from server except for ID's. ID's are mapped to correct
2451 ID entry and that is returned. Also, if channel entry is not sent
2452 by server but the notify is for channel the channel entry is sent
2453 to application (otherwise application doesn't know that it is for
2454 channel (library gets it from packet's Destination ID)).
2456 * Added silc_client_remove_from_channels into client library to
2457 remove a client from all channels it has joined to. Used when
2458 received SIGNOFF notify from server. Added also new function
2459 silc_client_replace_from_channels to replace old ID entry with
2460 new ID entry on all channels. Used when received NICK_CHANGE
2463 * Fixed ID Cache list handling in silc_idlist_get_client in
2464 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2465 to get (or query) client by ID.
2467 * Updated TODO list.
2469 * Added connection authentication status message defined by the
2470 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2471 support for these into the code in client and server side.
2473 * Added generic function silc_client_send_command to send any command
2474 with variable argument list. Application should use this function
2475 to send commands if the command functions provided by the library
2476 does not suite for the application's user interface needs.
2478 * Added new `failure' client operation. Application is notified about
2479 received failure packet if client is executing a protocol. In this
2480 case the protocol's execution has failed.
2482 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2483 is required by the protocol.
2485 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2486 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2489 * Added status flag to SilcSKE object to indicate realtime status
2490 of the SKE protocol.
2492 * Application receives now exactly same command reply arguments as
2493 the library receives from server. However, if ID is received the
2494 corresponding ID entry is returned to the application (eg. Client
2495 ID is mapped to correct SilcClientEntry entry and that is returned).
2496 Changed command_reply client operation due to this change.
2498 * Changed all ID's in commands and in command replys as ID Payloads.
2499 Change affected both client and server side codes.
2501 All ID's sent in SILC network (with execption of ID's in SILC
2502 Packet header) are sent in ID Payload to support variable length
2505 * Server now notifies nick changes and notifies all clients on
2506 the channels about the new nickname (about the new Client ID,
2509 * Implemented CMODE command to change channel modes. Supports all
2510 channel modes defined by the protocol specs except ban and invite
2511 lists. (Also, private channel key mode is supported but support for
2512 setting private channel key in client is missing, thus, this mode
2513 has no effect on client side (except that server requires that the
2514 client uses private channel key and normal channel traffic does not
2517 Also, invite mode works per se, but INVITE command does not work
2518 yet correctly, so you can set channel as invite only channel but
2519 inviting clients to the channel does not work (it is yet to be
2520 thought what's the best way to do it).
2522 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2523 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2524 Implemented CUMODE command to change user's mode on the channel.
2525 Supports all modes defined by the protocol specs.
2527 * Added NAMES command reply to return users modes on the channel.
2529 * Removed unnecessary and slow ciphers from lib/silccrypt.
2531 * Set SO_KEEPALIVE option to connection sockets by default.
2533 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2535 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2536 redefined the Notify Payload into protocol specs.
2538 * Added silc_id_payload_parse_id to get ID directly from raw
2541 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2544 accept searching by Client ID as well.
2546 * Added support for LEAVE and SIGNOFF notify types in client library.
2548 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2549 to parse ID Payload from raw data.
2551 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2553 * Added flags parameter into silc_ske_assemble_security_properties
2554 function in lib/silcske/silcske.[ch].
2556 * Changed notify client operation to fit better for notify messages
2557 sent by server. The notify payload received from server is now
2558 passed to the application (after parsing it to SilcNotifyPayload).
2559 It is application's responsibility to retrieve the arguments
2560 from the payload and show the message the way it wants. The message
2561 sent by server is implementation specific.
2563 * Changed public keys to comply with the protocol specification.
2564 Old public keys are not supported anymore and are not compatible.
2566 * Removed nickname from Channel Payload as the latest draft removed
2567 it. The client must resolve the nickname from the NAMES command
2568 reply received when it joined the channel.
2570 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2572 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Fixed some errors in protocol specification drafts.
2576 * Created lib/silccore/silcnotify.c to implement Notify Payload
2577 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2578 generic payloads described by protocol specifications. The file
2579 includes implementations for ID Payload and Argument Payload.
2581 * Changed Command Payload implementation to use the new Argument
2582 Payload. Changed command_xxxx_payload to command_payload_xxxx
2583 to comply with SILC coding conventions.
2585 * Added suppport for Argument Payload handling in Notify Payload
2586 implementation as protocol requires it. Added the new support
2587 into server and client lib as well.
2589 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Added support for multiple nicknames on same channel. [n] is
2592 added locally to the nickname if there are more than one same
2593 nicknames on the channel.
2595 * Server now sends all nicknames that matched WHOIS request.
2596 Client also shows the list received from server.
2598 * Added TOPIC command to client side. User can now set and show
2599 current topic on channel.
2601 * Added MOTD command to client and server. Also, server sends the
2602 motd when client connects to the server.
2604 * Changed version strings to comply ISO 8601.
2606 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Fixed protocol error handling in client library. It should now
2609 cope even if the SKE fails for some reason.
2611 * Made new protocol specification drafts for submitting to IETF.
2613 * Implemented TOPIC command to server in silcd/command.c.
2615 * Added two new notify types into lib/silccore/silcnotify.h:
2616 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2617 notify nickname change and topic setting/change on a channel.
2619 * API change of command_reply operation in client library. The
2620 application gets now the status type received from server as well.
2622 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2626 * Cras fixed and optimized the packet handling even further and
2627 it should work now. Minor change to the prototype of function
2628 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2630 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Added new function into lib/silcutil/silcschedule.[ch]:
2633 silc_schedule_with_fd to select() a specified fd. The function
2634 returns after timeout expires or data arrives or goes. The
2635 function is used by packet routines to wait that all data is
2636 received from network.
2638 * Fixed data reading from network in lib/silccore/silcpacket.c.
2639 The code now assures that all data is read from the fd and then
2640 continues packet processing. This was a bug fix since the code
2641 used to drop some data in some circumstances.
2643 * Added new function into lib/silcclient/client.[ch]:
2644 silc_client_start_key_exchange to start key exchange after
2645 connection has been established to server. The code internally
2646 now uses this funtion but its main purpose was to provide it
2647 for applications that perform their own connecting. After
2648 application has created a connection it merely calls this
2649 function to start the key exchange between client and server.
2650 The library takes care of everything else after that.
2652 Updated also lib/silcclient/README to explain the usage of
2655 * Do not send to application information that connection has
2656 been established. Application gets notified it by connect
2659 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Applied cras's patch to add silc_schedule_one function. The
2662 function runs scheduler once and returns.
2664 * Fixed the scheduler after cras messed it up. The timeout
2665 handling works now as it's supposed to work.
2667 * Added into lib/silccore/ silcnotify.h to include notify
2668 message types support. Changed silc_server_send_notify*
2669 functions, in server.[ch], to support those new notify types.
2670 Added the support for the notify types into client library,
2671 as well. Added new notify client operation into ops.h in
2674 * Changed silc_server_packet_send_to_channel to send normal
2675 packets instead of just channel message packets. The function
2676 is now used to send the notify packets to channels. It is not
2677 used to send channel message packets anymore, as server never
2680 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2681 va_arg()s as it seems to require it nowadays. I guess, if SILC
2682 is compiled with older va_arg() the new code should work anyway.
2684 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Splitted core library. Core library (lib/silccore) includes
2687 now only SILC protocol specific core (and common) components.
2688 Created new utility library (lib/silcutil) that includes more
2689 generic purpose stuff. The stuff for util library was taken
2690 from the old core library. This was minor and easy split.
2692 * Created SILC Client Library (lib/silcclient) that includes
2693 implementation of the SILC client without user interface. This
2694 was major move from silc/ directory. The code has been changed
2695 so that it is transparent towards the user interface. The
2696 silc/ directory includes now the same user interface as before
2697 and it uses the new client library. Read lib/silcclient/README.
2698 Basicly, the client library performs everything else related
2699 to SILC except user interface handling. Also, configuration
2700 files are considered to be part of user interface and library
2701 does not handle them.
2703 This change also changed a lot of structures, function naming etc.
2704 Most important change was that SilcClientWindow object was
2705 renamed to SilcClientConnection in the client library. Created
2706 also new file lib/silcclient/ops.h. Also added new files
2707 silc/local_command.[ch] and silc/client_ops.[ch].
2709 All these changes were made to make it easier for user interface
2710 designers to create what ever user interface for the SILC client
2713 It is also expected that the server will be moved to lib
2714 directory as well and SILC Server Library will be created;
2715 sometimes in the future.
2717 * Removed Local commands from lib/silccore/silccommand.h as
2718 they are application specific and new client library does not
2719 handle any of those anymore.
2721 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2722 old client implementation in silc/.
2724 * Added support for callback functions in SILC_LOG_* macros.
2725 Application can now set its own callbacks that will be called
2726 instead of using the default functions that will always print
2727 the debug messages to stderr (or stdout). Also, debugging can
2728 now be disabled by setting silc_debug to FALSE and re-enabled by
2729 setting it to TRUE. Note, that logging will still work even
2730 if debugging is disabled.
2732 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2733 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2734 silc_log_reset_debug_callbacks.
2736 * To enable debugging in silc client one must give now -d
2737 option on command line.
2739 * Changed silc_schedule_init to automatically allocate task queues
2740 if they are not allocated before calling it.
2742 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Added GMP 3.1 into math library.
2746 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2749 a channel in SILC network. The packet is used by servers and
2750 routers to notify other routers that user has left a channel.
2751 This little feature was missing until now. Added the feature
2752 to protocol specification as well.
2754 Added functions: silc_server_send_remove_channel_user and
2755 silc_server_remove_channel_user into server.[ch].
2757 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2758 lib/silccore/silcpacket.h. However, they are not implemented
2761 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Fixed joining to a channel and sending channel messages
2764 between server and router. The channel message sending should
2765 now work inside a cell.
2767 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Fixed the private message sending between server and router.
2770 The private message sending should now work inside a cell.
2772 * Added silc_server_replace_id into server.[ch] to replace
2773 existing ID in the SILC network.
2775 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2776 and silc_idlist_replace_server_id into idlist.[ch] in server.
2778 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Fixed the server to server connections. Server can again now
2781 connect to router. Router to router connections probably does
2784 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Added dynamic protocol registering support. Now protocols can
2787 registered and unregistered on the fly. Patch by cras.
2789 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added lib/contrib directory to hold routines that some platforms
2792 don't have but are needed by SILC.
2794 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2795 into lin/contrib to provide getopt() and getopt_long() for
2796 those who don't have it.
2798 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added AWAY command to client. When away message is set and
2801 client receives a private message packet the client automatically
2802 replies to the sender with the away message.
2804 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2805 bug seemed to be the cause of recent problems when compiling
2808 * Added version detection support to SKE protocol specification
2809 and added the new changes to the SKE implementation as well.
2810 There were other minor changes in the SKE protocol as well.
2812 Many changes in lib/silcske/silcske.[ch] and in
2813 lib/silcske/payload.[ch].
2815 * Added ^U functionality, clear input line. Patch from cras.
2817 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Mainly small bugfixes on core library. Fixed some debugging
2820 logging and buffer overflow in silclog.c.
2822 * Updated config.sub and config.guess on the distribution tree.
2824 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Added command lagging support in server. Client may execute
2827 commands now only once in two seconds.
2829 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Optimized packet reception. MAC computation and checking is now
2832 also more optimized. A lot previously duplicated code is now
2833 used as generic by both client and server.
2835 * Fixed key pair generation in clientutil.c
2837 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added into lib/silccore/silcbufutil.[ch] new function;
2840 silc_buffer_realloc.
2842 * Moved generic packet sending/encryption functions to
2843 lib/silccore/silcpacket.[ch] from client and server. Some
2844 rewriting of the functions.
2846 * Moved all generic packet reception/decryption functions to
2847 lib/silccore/silcpacket.[ch] from client and server. The
2848 packet processing is now much cleaner in both client and server.
2849 These were major changes in both client and server.
2851 * Created many common functions in server to do packet sending.
2852 Previously code were duplicated a lot, this has been removed
2855 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Rewrote major parts of the ID cache system. Don't know
2858 whether it is better now or not but at least the API is more
2861 * Major rewrite on ID cache stuff on client because of the ID
2862 cache API changes. Added idlist.c to client.
2864 * Also major rewrite on ID cache stuff on server as well.
2865 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2866 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2867 in hand, instead they are all put into the ID cache system now.
2868 All server_idlist_* routines uses ID cache now instead of
2869 traversing its own lists (those lists does not exist anymore).
2870 SilcIDList though still exists. Also, SilcXXXEntry's are
2873 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Finally made the SKE implementation compliant to the protocol
2876 specification. All mp integers are now binary encoded as
2877 opposed being HEX encoded.
2879 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2882 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2883 functions: silc_[encode/decode]_pem. Also added function
2884 silc_encode_pem_file to PEM encode with newlines ('\n') for
2887 * SILC public keys are now encoded either PEM or binary. Same
2888 option is for private keys as well. By default private keys
2889 are binary encoded and public keys PEM encoded. Silly HEX
2890 encoding were removed.
2892 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2893 function to create fingerprints.
2895 * Fixed a bug in SHA1; does not change the original data anymore.
2897 * Partly implemented INFO command on client and server side.
2898 Fixed CLEAR command. Changes to SERVER command; show current
2899 server(s) when giving command without arguments. Added
2900 VERSION command to client.
2902 * Added check to server that unregistered connections cannot
2903 execute commands (unless it is specificly allowed).
2905 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Fixed screen refresh.
2909 * Fixed channel joining bug from client. On some circumstances
2910 client tried to join to a channel it had already joined.
2912 * Added public key verification process into client's protocol.c.
2913 The client now verifies the public key from user and saves
2914 it into ~./silc/serverkeys/ directory.
2916 Added into: clientutil.[ch]: silc_client_verify_server_key.
2918 * Changed SKE protocol's silc_ske_initiator_finish function
2919 to accept callback function that verifies the received public
2920 key. Removed old silc_ske_verify_public_key function.
2922 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2925 silc_pkcs_private_key[_data]_set.
2927 * Made the password and public authentication more cleaner in
2928 server's protocol.c.
2930 * Removed historic and obsolete protocol `channel_auth' from
2931 both client and server.
2933 * Removed wrong way of sending command status messages from
2934 server to client in server's command.c. The old way violated
2935 protocol specification.
2937 Changes to silccore/silccommand.[ch]: removed
2938 silc_command_encode_status_payload -> not needed anymore,
2939 changed silc_command_encode_payload_va to accept extra
2940 argument on variable argument list. The argument type must
2941 now be provided to the function. Also, added new function:
2942 silc_command_encode_reply_payload_va which is same as
2943 normal command_encode_payload_va except command status type
2944 is provided as extra argument.
2946 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Added ~./silc directory handling. The directory includes the
2949 public and private keys for the client.
2951 Added silc_client_check_silc_dir, silc_client_create_identifier
2952 and silc_client_load_keys.
2954 * Implemented SILC protocol compliant public key. Added public
2955 and private key saving to and loading from files.
2957 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2958 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2959 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2960 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2961 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2963 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2964 silc_pkcs_load_[public/private]_key.
2966 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Added silc_server_get_route (route.[ch]) to get connection
2969 data for the fastest route for given ID.
2971 * Implemented INVITE command on client and server. The command
2972 were re-defined in the SILC Protocol Specification and the
2973 implementation now complies with the specification.
2975 * Implemented PING command on client and server.
2977 * Implemented NAMES command on client and server. The server side
2978 supports currently only normal server not router server yet.
2979 Some changes to NAMES definition in SILC protocol specification.
2981 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Implemented LEAVE command on client and server.
2985 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2986 again. This change was made to the protocol as well. Server
2987 should not violate the protocol specification anymore.
2989 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2992 was tested. SOCKS4 was not but should work anyway.
