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

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

446 environment. Added <server name> argument to the INFO command
447 reply. Updated the protocol specs.
449 * Fixed minor bug in silc_idcache_purge to not purge if the
450 expire value is zero.
452 * Fixed various bugs in WHOIS and IDENTIFY command handling as
453 they were buggy because of the WHOWAS information.
455 * Fixed local command MSG to handle the async resolving of
456 the remote client properly. It used to fail the first MSG.
457 Affected file silc/local_command.c.
459 * Added `data_len' field to SilcIDCache context.
461 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Update TODO. Todo in commands in the server.
465 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
468 used by routers as broadcast packet to inform other routers
469 about the changed user mode.
471 Implemented the notify handling in the server. Affected file is
472 silcd/packet_receive.c. Added the function
473 silc_server_send_notify_umode to the silcd/packet_send.[ch].
475 * Added new generic Channel Payload and deprecated the New Channel
476 Payload. The New Channel Payload is now the generic Channel
479 * Added new argument `mode' to the silc_server_send_new_channel
480 as it is required in the Channel Payload now.
482 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
483 and created a new and real SilChannelPayload to represent the
484 new generic Channel Payload. Implemented the encode/decode
485 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
487 * Added silc_server_get_client_channel_list to return the list
488 of channels the client has joined for WHOIS command reply.
489 Affected file silcd/server.[ch].
491 * Implemented the channel list sending in the WHOIS command reply
492 in server and in the client.
494 Implemented the channel list displaying on the user interface
495 as well. Affected file silc/client_ops.c.
497 * Added silc_channel_payload_parse_list to parse list of Channel
498 Payloads. It returns SilcDList list of SilcChannelPayloads.
499 Client for example can use this function to parse the list of
500 channels it receives in the WHOIS command reply. The caller
501 must free the list by calling silc_channel_payload_list_free.
502 Affected files lib/silccore/silcchannel.[ch].
504 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Added one new argument <user mode> to the WHOIS command reply
507 to return the mode of the user in SILC. Updated the protocol
510 Implemented it to the server and client.
512 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Fixed the mode printing on the user interface on joining.
515 Affected file silc/client_ops.c.
517 * Implemented the UMODE command and user modes in general to the
518 client library and to the user interface.
520 * Implemented the UMODE command to the server.
522 * The server now sends UNKNOWN_COMMAND error status if client sends
523 unknown command. Affected file silcd/command.c.
525 * All server commands now handle the command identifier the right
526 way when sending the command reply to the client. The client can
527 use to identify the command replies with the identifier.
529 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Added silc_server_get_client_route to resolve the route to
532 the client indicated by the client ID. Affected file is
535 * Added silc_server_relay_packet as general function to relay
536 packet to arbitrary destination. This deprecates functions
537 like _send_private_message_key, _relay_notify etc. Affected
538 file is silcd/packet_send.[ch].
540 Removed silc_server_send_key_agreement,
541 silc_server_send_private_message_key and
542 silc_server_packet_relay_notify functions from the file
543 silcd/packet_send.[ch].
547 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
548 server. Affected file silcd/packet_receive.[ch].
550 * Implemented the KILL command to the client. Implemented the
551 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
552 Affected files lib/silcclient/command[_reply].c and
553 lib/silcclient/client_notify.c. Implemented the KILL notify
554 printing in the user inteface.
556 * Fixed a lot silc_parse_nick memory leaks from the client
557 library in the file lib/silcclient/command.c.
559 * Changed the silc_server_send_notify_on_channels's `sender'
560 argument from SilcSocketConnection to SilcClientEntry to
561 check the sender as entry and not as connection object and not
562 to send to the client provided as argument. The affected file
563 is silcd/packet_send.[ch].
565 * The notify packets that are destined directly to the client used
566 to not to be processed by the server. Now changed that and the
567 server processes all notify packets. After relaying the packet
568 to the client the notify packet is processed in the server.
570 * The silc_server_free_client_data now checks whether there is
571 pending outgoing traffic for the client and purges the data to
572 the network before removing the client entry.
574 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
577 an client is killed from the SILC Network. Updated the protocol
580 Added new function silc_server_send_notify_killed to the
581 silcd/packet_send.[ch].
583 * Added function silc_server_packet_relay_notify to relay notify
584 packets that are destined directly to a client. In this case
585 the server does not process the notify packets but merely relays
586 it to the client. Affected file silcd/packet_send.[ch].
588 Added also silc_server_packet_process_relay_notify to check
589 whereto relay the notify. Affected file is
590 silcd/packet_receive.[ch].
592 * Implemented the KILL command to the server.
596 * Added the backup schema desgined last fall to the protocol
597 specs for everyone to see. The specification is in the
598 *-spec-xx.txt draft and the packet type definitions for the
599 backup routers is in *-pp-xx.txt draft. Thusly, added also
600 new packet type SILC_PACKET_CELL_ROUTERS.
602 * A big security problem in the implementation discovered. The
603 signoff of an client did not cause new channel key generation
604 which it of course should've done. The channel keys must be
605 always re-generated when client leaves (or signoffs) the channel.
606 The silc_server_remove_from_channels funtion now handles
607 the channel key re-generation.
609 * Added `sender' argument to the silc_server_send_notify_on_channels
610 to not to send the client provided as argument. Affected file
611 silcd/packet_send.[ch].
613 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Implemented OPER and SILCOPER commands into the server and
618 * Added silc_auth_verify and silc_auth_verify_data to verify
619 the authentication directly from the authentication payload.
620 It supports verifying both passphrase and public key based
621 authentication. Affected file lib/silccore/silcauth.[ch].
623 * Added `hash' field to the SilcIDListData structure. It is the
624 hash negotiated in the SKE protocol. Affected file is
627 * Slight redesigning of the SilcAuthPayload handling routines.
628 Do not send SilcPKCS but SilcPublicKey as argument.
630 * Implemented the public key authentication support to the
631 serverconfig. The public key is loaded from the provided path
632 and saved as authentication data to void * pointer. Thus,
633 changed the unsigned char *auth_data to void *auth_data;
635 * Fixed SHUTDOWN command to send the reply before the server
636 is shutdown. :) Affected file silcd/command.c.
638 * Fixed fatal bug in CONNECT command. The hostname was invalid
639 memory and server crashed. Affected file silcd/command.c.
641 * Fixed fatal bug in CLOSE command. The server_entry became
642 invalid but was referenced later in the command. Affected file
645 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Fixed fatal bug in failure packet handling. Server ignored
648 the failure and thus crashed when it came.
652 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
655 that the command may be executed only once in (about) 2 seconds.
656 The old SILC_CF_LAG flag is same but allows command bursts up
657 to five before limiting.
659 Added the support for CF_LAG and CF_LAG_STRICT flags to the
660 server code. Various commands now includes the CF_LAG_STRICT
661 flag to disallow any kind of miss-use of the command.
663 * Fixed the silc_buffer_unformat to not to allocate any data
664 if the length of the data is zero. It used to allocate the
665 length + 1. Affected file lib/silcutil/silcbuffmt.c.
667 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Changed the format of AdminConnection configuration section
670 in the server. Added username of the admin to the format.
671 Affected files silcd/serverconfig.[ch].
673 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
674 to return admin configuration data by host, username and/or
677 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Implemented WHOWAS command to the server. Added the functions:
681 silc_server_command_whowas_parse,
682 silc_server_command_whowas_send_reply,
683 silc_server_command_whowas_from_client and
684 silc_server_command_whowas_from_server
686 * Added <Client ID> argument to the WHOWAS command reply. Updated
687 the protocol specs accordingly.
689 * Implemented WHOWAS command and command_reply to the client
692 Implemented the WHOWAS printing on the user interface.
694 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Added new argument to the WHOWAS command reply, the real name.
697 It is an optional argument. Updated the protocol specs.
699 * Added SilcIDCacheDestructor callback that is registered when
700 the SilcIDCache is allocated. The callback is called when
701 an cache entry in the ID Cache expires, or is purged from the
702 cache. Added into lib/silccore/idcache.[ch].
704 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
705 to destruct the client entries when the cache entry expires.
706 Other ID Cache's in server and in the client library ignores
709 * If the ID Cache entry's `expire' field is zero then the entry
710 never expires. Added boolean `expire' argument to the
711 silc_idcache_add function in the lib/silccore/idcache.[ch].
712 If it is TRUE the default expiry value is used.
714 * Added silc_server_free_client_data_timeout that is registered
715 when client disconnects. By default for 5 minutes we preserve
716 the client entry for history - for WHOWAS command.
718 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Added support to the server to enforce that commands are not
721 executed more than once in 2 seconds. If server receives
722 commands from client more frequently, timeout is registered
723 to process the commands. Affected file silcd/command.c.
724 Added new function silc_server_command_process_timeout.
726 * Changed NICK_NOTIFY handling in client library to check that
727 if the client's nickname was changed, so there is no need to
728 resolve anything from the server.
730 * Removed error printing from the WHOIS and IDENTIFY commands.
731 If error occurs then it is ignored silently in the client library.
732 The application, however, may map the received error to
733 human readable error string. The application currently maps
734 the NO_SUCH_NICKNAME error to string.
736 * Made the command status message public to the application. Moved
737 them from lib/silcclient/command_reply.c to
738 lib/silcclient/command_reply.h. The application can map the
739 received command status to the string with the
740 silc_client_command_status_message function.
742 * Added check to the server to check that client's ID is same
743 as the Source ID in the packet the client sent. They must
746 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Added dist-bzip hook to the Makefile.am to make bzip2
749 compressed distributions.
751 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Server now enforces the maximum length for the nickname and
754 the channel as protocol specification dictates. 128 bytes for
755 nickname and 256 bytes for channel name.
757 * Moved the WHOIS printing to the application. The client libary
758 does not print out the WHOIS information anymore, the application
759 must do it. Renamed silc_client_command_reply_whois_print to
760 the silc_client_command_reply_whois_save.
762 The client's idle time is also sent to the application now, and
763 the idle is shown on screen.
765 * Added silc_client_command_reply_identify_save to save the
766 received IDENTIFY entries.
768 * Do not check for channel private keys in message sending and
769 reception if the channel does not have the PRIVKEY mode set.
770 Affected file lib/silclient/client_channel.c.
772 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
775 just surfaced after chaning the JOIN procedure.
777 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Added silc_client_get_clients_by_list to get client entries
780 from Client ID list, that is returned for example by JOIN
781 and USERS command replies. The application should use this
782 function for example when JOIN command reply is received to
783 resolve the clients already on the channel (library does not
784 do that anymore as USERS command reply is not used in the JOIN
785 procedure anymore). Affected files lib/silcclient/silcapi.h and
786 lib/silcclient/idlist.c.
788 * JOIN command reply and USERS command reply returns now SilcBuffer
789 pointers instead of unsigned char pointers when returning
790 the client list and mode list.
792 * Added <Client ID> argument to the JOIN command reply, mainly
793 for the server to identify for which client the command was
794 originally sent. Updated protocol specs accordingly.
796 * Added SilcDlist private_key pointer to the SilcChannelEntry
797 in the client to support the channel private keys. Affected
798 file is lib/silcclient/idlist.h.
800 * Added SilcChannelPrivateKey argument to the function
801 silc_client_send_channel_message so that application can choose
802 to use specific private ke if it wants to. If it is not provided,
803 the normal channel key is used, unless private keys are set.
804 In this case the first (key that was added first) is used
805 as the encryption key.
807 * Implemented the support for channel private key handling.
808 Implemented the following functions:
810 silc_client_add_channel_private_key,
811 silc_client_del_channel_private_keys,
812 silc_client_del_channel_private_key,
813 silc_client_list_channel_private_keys and
814 silc_client_free_channel_private_keys
816 Affected file lib/silcclient/client_channel.c.
818 * Added the support for the private keys in the channel message
819 sending and encryption and in the message reception and
820 decryption. Affected funtions are
821 silc_client_send_channel_message and silc_client_channel_message.
823 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Added SKE's key verify callback to the client library's
826 KE protocol context. Affected files lib/silcclient/protocol.[ch].
828 * Removed the statement that server (or router) must send USERS
829 command reply when joining to the channel so that the client
830 knows who are on the channel. Instead, the client list and
831 client's mode list is now sent in the JOIN command reply to the
832 client who joined channel. This is better solution.
834 * Added function silc_server_get_users_on_channel and function
835 silc_server_save_users_on_channel to the silcd/server.[ch].
837 * Removed function silc_server_command_send_users from the
840 * Do not show topic on the client library anymore. The topic is
841 sent in the command reply notify to the application and the
842 application must show the topic now.
844 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Added client searching by nickname hash into the IDENTIFY and
847 WHOIS commands in the server as they were clearly missing from
848 them. Affected file is silcd/command.c.
850 * Fixed a bug in private message receiving in the client library.
851 The remote ID was freed and it wasn't supposed, now it is
854 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Minor fix to the channel payload; allocate the data area, as it
857 needs to be of specific length.
859 * If the key agreement port is zero then the operating
860 system will define the bound port. Affected files are
861 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
863 * Added new function silc_channel_payload_decrypt into the file
864 lib/silccore/silcchannel.[ch].
866 * Moved the channel message etc, check from silc_packet_decrypt
867 to applications. The library calls now a generic
868 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
869 when the packet is either normal or special. This was done to
870 allow more wide range of checking that was not allowed when
871 the code was in library. Now applications can do virtually any
872 checks to the packet and return to the library the decision how
873 the packet should be processed. Affected files are
874 lib/silccore/silcpacket.[ch].
876 Added silc_server_packet_decrypt_check to the server and
877 silc_client_packet_decrypt_check to the client library.
879 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
880 to send with specified source and destination information.
882 * Channel message delivery between routers was broken after the
883 channel key distribution was fixed earlier. The channel key
884 was used be to distributed to other routers as well which is not
885 allowed by the protocol. Now this is fixed and channel keys
886 really are cell specific and the channel message delivery between
887 routers comply with the protocol specification.
889 * Fixed various commands in server to check also the global list
890 for the channel entry and not just the local list. The affected
891 file silcd/command.c.
893 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Added assert()s to buffer formatting and unformatting routines
896 to assert (if --enable-debug) when error occurs. Affected
897 file: lib/silcutil/silcbuffmt.c.
899 * Changed to auto-reconnect to check whether the remote host is
900 router and register the re-connect timeout if it is. It used
901 to check that whether we are normal server, but router must do
902 auto-reconnect with another router as well. Affected file
905 * Removed the [<key len>] option from CMODE command as the cipher
906 name decides the key length, nowadays. See the defined ciphers
907 from the protocol specification.
909 * Added [<hmac>] option to the CMODE command to define the HMAC
910 for the channel. Added SILC_CMODE_HMAC channel mode.
912 * Added [<hmac>] option for the JOIN command so that user can
913 select which HMAC is used to compute the MACs of the channel
916 * Added Hmac field to the Channel Message Payload. The integrity
917 of plaintext channel messages are now protected by computing
918 MAC of the message and attaching the MAC to the payload. The
919 MAC is encrypted. Now, it is clear that this causes some
920 overhead to the size of the packet but rationale for this is that
921 now the receiver can verify whether the channel message decrypted
922 correctly and also when private keys are set for the channel the
923 receiver can decrypt the packet with several keys and check from
924 the MAC which key decrypted the message correctly.
926 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
927 lib/silccrypt/silccipher.[ch].
929 * Added silc_hash_len to return the digest length into the
930 lib/silcrypt/silchash.[ch].
932 * Rewrote parts of Silc Channel Payload interface in the
933 lib/silccore/silcchannel.[ch]. The encode function now also
934 encrypts the packet and parse function decrypts it.
936 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Fixed a minor formatting bug in the SKE's key material processing.
939 It actually might have processed the keys wrong way resulting
942 * Redefined the mandatory HMAC algorithms and added new algorithms.
943 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
944 and hmac-md5 truncated to 96 bits. The mandatory is now
945 hmac-sha1-96. Rest are optional (including the one that used
946 to be mandatory). Rationale for this is that the truncated HMAC
947 length is sufficient from security point of view and can actually
948 make the attack against the HMAC harder. Also, the truncated
949 HMAC causes less overhead to the packets. See the RFC2104 for
952 * Added new [hmac] configuration section. The SKE used to use
953 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
954 is of course wrong. The official names that must be proposed in
955 the SKE are the ones defined in the protocol specification
956 (hmac-sha1-96 for example). The user can configure any hmac
957 using any hash function configured in the [hash] section. At
958 least, the mandatory must be configured.
960 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
962 * Added HMAC list to the SKE proposal list. It has now both
963 hash algorithm list and HMAC list. This makes the protocol
964 incompatible with previous versions. The SKE now seems to work
965 the way it is supposed to work, for the first time actually.
967 * Defined plain Hash algorithms to the protocol specification.
970 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Implemented support for key agreement packets into the server.
973 Added functions silc_server_key_agreement and
974 silc_server_send_key_agreement. Other than these functions,
975 server has nothing to do with this packet.
977 * Added support for private message key packets into the server.
978 Added functions silc_server_private_message_key and
979 silc_server_send_private_message_key.
983 * Changed the silc_[client|server]_protocol_ke_set_keys to be
984 called in the protocol's final callback instead in the END
985 protocol state. This makes a little more sense and in the same
986 time in client we can use the same protocol routines for normal
987 key exchange and to key agreement packet handling as well.
989 * Added to both client's and server's KE protocol context the
990 SilcSKEKeyMaterial pointer to save the key material. We will
991 bring the key material to the protocol's final callback by doing
992 this. The final callback must free the key material.
994 * Added SKE's packet_send callback into client's KE protocol
995 context so that the caller can choose what packet sending function
996 is used. This way we can use different packet sending when
997 doing normal SKE when doing key agreement packet handling (in
998 the key agreement packet handling we do not want to encrypt
1001 * Implemented the responder side of the key agreement routines
1002 in the client. The client can now bind to specified port and
1003 accept incoming key negotiation. The key material is passed
1004 to the application after the protocol is over.
1006 * Implemented the processing of incoming Key Agreement packet
1007 in the client. Added function silc_client_key_agreement to
1010 * Implemented the intiator side of the key agreement routines
1011 in the client. The client can now initiate key agreement with
1012 another remote client. The key material is passed to the
1013 application after the protocol is over.
1015 * Created client_keyagr.c to include all the key agreement
1018 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1019 SILC_TASK_CALLBACK except that it is not static.
1021 * Created client_notify.c and moved the Notify packet handling
1022 from the client.[ch] into that file.
1024 * Created client_prvmsg.c and moved all private message and
1025 private message key routines from the client.[ch] into that file.
1027 * Create client_channel.c and moved all channel message and
1028 channel private key routines from the client.[ch] into that file.
1030 * Changed silc_client_get_client_by_id_resolve to resolve with
1031 WHOIS command instead of IDENTIFY command, in the file
1032 lib/silclient/idlist.c.
1034 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Implemented the SKE's responder side to the Client library.
1038 * When FAILURE is received to the protocol do not trust it
1039 blindly. Register a timeout to wait whether the remote closes
1040 the connection as it should do it, only after that process the
1041 actual failure. This was changed to both client and server.
1043 * Added client_internal.h to include some of the structures
1044 there instead of client.h in lib/silcclient/.
1046 * Added function silc_task_unregister_by_callback to unregister
1047 timeouts by the callback function.
1049 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Some "Incomplete WHOIS info" errors has been appearing on the
1052 log files. Took away the entry->userinfo check from WHOIS
1053 reply sending. The entry->userinfo is now " " if client did not
1054 provide one. I thought this was fixed earlier but something
1055 is wrong still. Let's see if the error still appears.
1057 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Fixed a minor bug in the login when the channel key is
1060 re-generated in the server. It used to generate the key in
1061 wrong order and thus caused problems in the channel traffic.
1063 * Fixed a minor bug in channel key distsribution after
1064 KICK command. The key was not sent to the router even though
1067 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added silc_ske_process_key_material_data as generic routine
1070 to process any key material as the SILC protocol dictates. The
1071 function is used by the actual SKE library but can be used by
1072 applications as well. This relates to the private message keys
1073 and the channel private keys since they must be processed the
1074 same way the normal SILC session keys. The protocol dictates
1075 this. Affected files: lib/silcske/silcske.[ch].
1077 Added also silc_ske_free_key_material to free the
1078 SilcSKEKeyMaterial structure.
1080 * Defined silc_cipher_set_key function to set the key for
1081 cipher without using the object's method function. The affected
1082 files: lib/silccrypt/silccipher.[ch].
1084 * Implemented silc silc_client_add_private_message_key,
1085 silc_client_add_private_message_key_ske,
1086 silc_client_del_private_message_key,
1087 silc_client_list_private_message_keys and
1088 silc_client_free_private_message_keys functions in the
1091 Added functions silc_client_send_private_message_key to send
1092 the Private Message Key payload and silc_client_private_message_key
1093 to handle incoming Private Message Key payload.
1095 * Added Cipher field to the Private Message Key payload to set
1096 the cipher to be used. If ignored, the default cipher defined
1097 in the SILC protocol (aes-256-cbc) is used.
1099 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Removed lib/silcclient/ops.h file.
1103 Redefined parts of the SILC Client Library API. Created new
1104 file silcapi.h that deprecates the ops.h file and defines the
1105 published Client Library API. Defined also private message key
1106 API and channel private key API into the file.
1108 This is the file that the application must include from the
1109 SILC Client Library. Other files need not be included by
1110 the application anymore.
1112 * Added new key_agreement client operation callback and also
1113 defined the Key Agreement library API for the application.
1115 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1118 is used by clients to request key negotiation between another
1119 client in the SILC network. If the negotiation is started it
1120 is performed using the SKE protocol. The result of the
1121 negotiation, the secret key material, can be used for example
1122 as private message key.
1124 Implemented the Key Agreement payload into the files
1125 lib/silccore/silauth.[ch].
1127 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Redefined ciphers for the SILC protocol. Added some new ciphers
1130 and defined the key lengths for the algorithms. Changed the
1131 code accordingly. The default key length is now 256 bits.
1133 * Fixed SKE key distribution function silc_ske_process_key_material
1134 when the key length is more than 128 bits. The default key
1135 length in SILC is now 256 bits.
1137 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1138 to indicate unsupported algorithm.
1140 * Renamed rijndael.c to aes.c and all functions as well.
1142 * Fixed a long standing channel key setting bug in client library.
1143 Weird that it has never surfaced before.
1145 * Fixed bug in channel deletion. If the entire channel is removed
1146 then it must also delete the references of the channel entry
1147 from the client's channel list as the client's channel entry and
1148 the channel's client entry share same memory.
1150 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Implemented CONNECT and SHUTDOWN commands in the client.
1154 * Implemented CLOSE command to the client.
1156 * Added the function silc_idlist_find_server_by_name into the
1157 files silcd/idlist.[ch].
1159 Added the function silc_idlist_find_server_by_conn into the
1160 files silcd/idlist.[ch].
1162 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * DIE command was renamed to SHUTDOWN. Updated the both code
1167 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1168 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1170 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1173 * Added function silc_server_create_connection function to create
1174 connection to remote router. My server implementation actually
1175 does not allow router to connect to normal server (it expects
1176 that normal server always initiates the connection to the router)
1177 so the CONNECT command is only good for connecting to another
1180 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1183 or some other client was kicked from the channel.
1185 Implemented the handling of the notify type to both client
1188 Implemented silc_server_send_notify_kicked to send the KICKED
1189 notify. It is used to send it to the server's primary router.
1191 * Implemented the KICK command into server and client.
1193 * Added `query' argument to the silc_idlist_get_client function
1194 to indicate whether to query the client from server or not if
1197 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1198 to indicate that the client is not channel founder.
1202 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Removed the rng context from SilcPacketContext structure and
1205 changed that the packet routine uses the Global RNG API.
1207 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Added support for quit message that client can "leave" on the
1210 channel when it quits the SILC. It is ditributed inside the
1211 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1213 Added silc_server_free_client_data that will take the
1214 signoff message as argument.
1216 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1218 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Updated parts of the protocol specification to keep it up
1223 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1226 payloads in one packet.
1228 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1229 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1230 use now the new List flag.
1232 * Also deprecated the following packet types: REPLACE_ID,
1233 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1235 * Added list support for Notify packet in server.
1237 * Added silc_server_send_notify_channel_change to send the
1238 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1239 the silc_server_send_replace_id.
1241 * Added silc_server_send_notify_nick_change to send the
1242 NICK_CHANGE notify type. Deprecates the function
1243 silc_server_send_replace_id.
1245 * Added silc_server_send_notify_join to send the JOIN notify type.
1246 Deprecates the function silc_server_send_new_channel_user.
1248 * Added silc_server_send_notify_leave to send LEAVE notify type.
1249 Deprecates the function silc_server_send_remove_channel_user.
1251 * Added silc_server_send_notify_cmode and
1252 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1253 types. Deprecates the silc_server_send_set_mode function.
1255 * Added SERVER_SIGNOFF notify type to indicate that server has
1256 quit. This means that all clients on the channel from that
1257 server will drop. This can be also used when netsplit happens.
1259 Deprecated REMOVE_ID packet type since it is not needed anymore
1262 Added silc_server_send_notify_server_signoff to send the
1263 SERVER_SIGNOFF notify type. Deprecates the function
1264 silc_server_send_remove_id.
1266 Added also silc_server_send_notify_signoff to send the
1267 SIGNOFF notify type.
1269 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1270 SILC protocol from this day on. Changed the protocol
1271 specification as well.
1273 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1274 notify type. It is used between routers to notify about
1275 topic changes on a channel.
1277 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1280 * Partly updated the protocol specification to comply with the
1281 changes now made. It is still though a bit outdated.
1283 * The JOIN notify type now takes one extra argument <Channel ID>.
1284 The packet used to be destined to the channel but now the
1285 JOIN type may be sent as list thus it is impossible to
1286 destine it to any specific channel. By adding this argument
1287 it is again possible.
1289 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Added CREDITS file. The CHANGES and CREDITS file will appear
1292 in the distribution as well.
1294 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1297 types in the server's silcd/packet_receive.c.
1299 * Implemented CMODE and CUMODE to work in router environment.
1301 * Fixed minor encoding and decoding buglet from the
1302 lib/silccore/silcmode.c.
1304 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1307 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1309 * Changed all SilcConfigServer* and silc_config_server* to
1310 SilcServerConfig* and silc_server_config*, respectively.
1313 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Associated the ID (client or server ID) to the Authentication
1316 Payload to avoid any possibility of forging. Updated the
1317 protocol specification and the code accordingly.
1319 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * The RSA key length is now save to the RsaKey context in the
1322 key generation process in lib/silccrypt/rsa.c. The key length
1323 is now used to figure out the maximum size of the block allowed
1324 to be encrypted/signed.
1326 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1327 is equivalent to the silc_mp_mp2bin but does not allocate any
1330 * Changed silc_mp_mp2bin API to take length argument. If it is
1331 non-zero then the buffer is allocated that large. If zero, then
1332 the size is approximated using silc_mp_sizeinbase, which however
1335 * Created Global RNG API which is global RNG that application can
1336 initialize. After initializing, any routine anywhere in the
1337 code (including library) can use RNG without allocating a new
1338 RNG object. This was done to allow this sort of use of the
1339 RNG in code that has no chance to allocate RNG object. All
1340 applications currently allocate this and many routines in the
1341 library use this. Affected file lib/silccrypt/silcrng.[ch].
1343 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1344 it to use the Global RNG API.
1346 * Defined Authentication Payload into protocol specification that
1347 is used during SILC session to authenticate entities. It is
1348 used for example by client to authenticate itself to the server
1349 to obtain server operator privileges.
1351 Implemented this payload into the lib/silccore/silcauth.[ch].
1352 Implemented also routines for public key based authentication
1353 as the new protocol specification dictates.
1355 Moved definitions of different authentication methods from
1356 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1358 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1359 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1360 silc_pkcs_verify_with_hash functions into the file
1361 lib/silccrypt/silcpkcs.[ch].
1363 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * The client entry's userinfo pointer must be always valid.
1366 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1367 will fail since it requires the userinfo. Now, the userinfo
1368 is allocated as "" if actual userinfo does not exist. Actually,
1369 it must exist and it is totally Ok to drop client connections
1370 that does not announce the userinfo. However, we will make
1371 this workaround for now.
1373 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1374 to return the remote port by socket.
1376 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1379 SILC_SERVER_PENDING_EXEC and added an new macro
1380 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1381 data or when error occurs while processing the pending command.
1383 Added new argument `destructor' into silc_server_command_pending
1384 and to the SilcServerCommandPending object. This destructor is
1385 now called after calling the pending callback or if error occurs
1386 immediately. If error occurs the actual pending callback won't
1387 be called at all - only the destructor. The destructor may be
1388 NULL if destructor is not needed.
1390 All this applies for client library code as well. Similar
1391 changes were made there as well for the pending commands.
1393 In the client, the application must now allocate the
1394 SilcClientCommandContext with the silc_client_command_alloc
1397 * Added reference counter to the SilcServerCommandContext. Added
1398 function silc_server_command_alloc and silc_server_command_dup
1401 Same type of functions added to the client library for the same
1404 * Removed the cmd_ident from IDListData away since it is now
1405 global for all connections. It is the command identifier used
1406 in command sending and with pending commands. The affected file
1409 * Added reference counter to the SilcSocketConnection objecet to
1410 indicate the usage count of the object. The object won't be
1411 freed untill the reference counter hits zero. Currently only
1412 server uses this, and client ignores it. The client must be
1413 set to use this too later. The affected files are
1414 lib/silccore/silcsockconn.[ch]. Added also the function
1415 silc_socket_dup to increase the reference counter.
1417 This was mainly added because it is possible that the socket
1418 is removed underneath of pending command or other async
1419 operation. Now it won't be free'd and proper DISCONNECTING
1420 flags, etc. can be set to avoid sending data to connection that
1421 is not valid anymore.
1423 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1424 the connection. After that it sets SILC_SET_DISCONNECTED.
1425 It is, however, possible that the socket data is not still freed.
1426 The silc_server_packet_process now checks that data is not
1427 read or written to connection that is DISCONNECTED. The socket
1428 get's freed when the reference counter hits zero.
1430 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1432 * Changed the client operation API: channel_message operation's
1433 `sender' is now the client entry of the sender, not the nickname
1434 and the `channel' is the channel entry, not the channel name.
1436 In the private_message operation the `sender' is now also the
1437 client entry of the sender not the nickname.
1439 Affected file is lib/silcclient/ops.h and all applications
1440 using the client operations.
1442 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Moved the calling of ops->connect() from connect_to_server_final
1445 into receive_new_id functin since that is the point when the
1446 client is actually allowed to send traffic to network. The
1447 affected file is lib/silcclient/client.c.
1449 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1452 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1453 (if needs broadcasting) instead of broadcasting the packets one
1454 by one which would make a burst in the network traffic.
1456 * Added `broadcast' argument to the functions in silcd/server.[ch]
1457 silc_server_create_new_channel[_with_id] to indicate whether
1458 to send New Channel packet to primary router.
1460 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1462 * Added new function into the silcd/server.[ch] files:
1463 silc_server_create_new_channel_with_id to create new channel with
1464 already existing Channel ID.
1466 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1467 lib/silccore/silcpacket.h. This packet is used t send list of
1468 Set Mode payloads inside one packet. Server uses this to set
1469 the modes for the channels and clients on those channels, that it
1470 announced to the router when it connected to it. The protocol
1471 specification has been updated accordingly.
1473 * The silc_server_new_channel did not handle the packet coming
1474 from normal server as it normally does not send that. However,
1475 when it announces its channels it does send it. Implemented
1476 the support for that.
1478 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1479 into the file lib/silccore/id.h.
1481 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Fixed memory leaks in the functions silc_idlist_del_client,
1484 silc_idlist_del_channel and silc_idlist_del_server in the file
1485 silcd/idlist.c. All of those leaked like a sieve.
1487 * Fixed some small memory leaks in the client's function
1488 silc_client_notify_by_server.
1490 * Added functions into silcd/server.c: silc_server_announce_clients,
1491 silc_server_announce_channels and silc_server_announce_server.
1492 These functions are used by normal and router server to announce
1493 to its primary router about clients, channels and servers (when
1494 router) that we own. This is done after we've connected to the
1497 These functions effectively implements the following packet types:
1498 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1499 and SILC_PACKET_NEW_ID_LIST.
1501 * Added new functions into the silcd/packet_receive.[ch]:
1502 silc_server_new_id_list, silc_server_new_channel_list and
1503 silc_server_new_channel_user_list to handle the incoming
1504 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1506 * Added support of changing Channel ID in the function
1507 silc_server_replace_id. If the server that announces a channel
1508 to the router already exists in the router (with same name but
1509 with different Channel ID), router is responsible to send
1510 Replace ID packet to the server and force the server to change
1511 the Channel ID to the one router has.
1513 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1514 client that the Channel ID has been changed by the router. The
1515 normal server sends this to the client. Client must start using
1516 the new Channel ID as the channel's ID.
1518 Implemented handling of this new type into lib/silcclient/client.c
1519 into the function silc_client_notify_by_server.
1521 * Added new function silc_idlist_replace_channel_id into the files
1522 silcd/idlist.[ch] to replace the Channel ID.
1524 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Call silc_server_command_identify_check always when processing
1527 the IDENTIFY command in silcd/command.c
1529 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1532 send keepalive packets. The packet can be sent by clients,
1533 servers and routers.
1535 Added function silc_socket_set_heartbeat into the file
1536 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1537 If not set, the heartbeat is not performed. The actual
1538 heartbeat is implemented in the low level socket connection
1539 library. However, application is responsible of actually
1542 Added silc_server_send_heartbeat to send the actual heartbeat
1543 packet into silcd/packet_send.[ch]. Server now performs
1544 keepalive with all connections.
1546 * Added silc_task_get_first function into lib/silcutil/silctask.c
1547 to return the timeout task with shortest timeout. There was a bug
1548 in task unregistration that caused problems. TODO has been
1549 updated to include that task system must be rewritten.
1551 * The client library will now resolve the client information when
1552 receiving JOIN notify from server for client that we know but
1553 have incomplete information.
1555 * Rewrote parts of silc_server_remove_from_channels and
1556 silc_server_remove_from_one_channel as they did not remove the
1557 channel in some circumstances even though they should've.
1559 * Encryption problem encountered in server:
1561 The LEAVE command used to send the Channel Key packet to the
1562 router immediately after generating it. However, the code
1563 had earlier sent Remove Channel user packet but not immediately,
1564 ie. it was put to queue. The order of packets in the router
1565 was that Channel Key packet was first and Remove Channel User
1566 packet was second, even though they were encrypted in the
1567 reverse order. For this reason, MAC check failed. Now, this
1568 is fixed by not sending the Channel Key packet immediately but
1569 putting it to queue. However, this is more fundamental problem:
1570 packets that are in queue should actually not be encrypted
1571 because packets that are sent immediately gets encrypted
1572 actually with wrong IV (and thus MAC check fails). So, packets
1573 that are in queue should be encrypted when they are sent to
1574 the wire and not when they put to the queue.
1576 However, the problem is that the current system has not been
1577 designed to work that way. Instead, the packet is encrypted
1578 as soon as possible and left to the queue. The queue is then
1579 just purged into wire. There won't be any fixes for this
1580 any time soon. So, the current semantic for packet sending
1583 o If you send packet to remote host and do not force the send
1584 (the packet will be in queue) then all subsequent packets to the
1585 same remote host must also be put to the queue. Only after the
1586 queue has been purged is it safe again to force the packet
1589 o If you send all packets immediately then it safe to send
1590 any of subsequent packets through the queue, however, after
1591 the first packet is put to queue then any subsequent packets
1592 must also be put to the queue.
1594 Follow these rules and everything works fine.
1596 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Added new function silc_server_remove_clients_by_server to
1599 remove all client entries from ID list when the server connection
1600 is lost. In this case it is also important to invalidate all
1601 client entires as they hold the invalid server entry. This
1602 fixes fatal bug when server has lost connection and will reconnect
1605 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Made some sanity checks to silc_server_daemonise like to check
1608 whether the requested user and group actually exists.
1610 * Added sanity check to SKE's silc_ske_responder_finish to check
1611 that the public and private key actually is valid.
1613 * Invalidate the client's nickname when receiving Replace ID
1614 packet and the Client ID is being replaced. This means that the
1615 server will query the nickname if someone needs it (client)
1618 * Sort the ID Cache in client library when the ID Cache data
1619 has changed (needs sorting).
1621 * Do not allow for SILC client to create several connections to
1622 several servers. The client does not support windows right now
1623 and generating multiple connections causes weird behaviour.
1625 Irssi-silc client does support windows and can handle several
1626 connections without problems, see: www.irssi.org and SILC plugin.
1628 * Fixed some places where client was added to the IDList. The
1629 rule of thumb is following (in order to get everything right):
1630 If the client is directly connected local client then the
1631 `connection' argument must be set and `router' argument must be
1632 NULL to silc_idlist_add_client function. If the client is not
1633 directly connected client then the `router' argument must
1634 bet set and the `connection' argument must be NULL to the
1635 silc_idlist_add_client function.
1637 * The funtion silc_server_packet_send_local_channel actually did
1638 not check whether the client was locally connected or not. It
1639 does that now. Fixed a bug related to LEAVE command.
1641 * Fixed Remove Channel User payload parsing bug in server's
1642 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1644 * The server's silc_server_save_channel_key now checks also the
1645 global ID list for the channel as it might not be in the local
1646 list. Fixed a bug related to LEAVE command.
1648 * Is this the end of the [<unknown>] buglet that has been lurking
1649 around for a long time? A little for loop fix in server's
1650 silc_server_command_whois_parse that is used by both IDENTIFY
1651 and WHOIS command. At least, this was a clear bug and a cause
1652 of one type of [<unknown>] buglet.
1654 * WHOIS and IDENTIFY commands call the function
1655 silc_server_command_[whois/identify]_check function even if
1656 we are not router server.
1658 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Added --with-gmp configuration option. If set the GMP
1661 is always compiled in the SILC source tree. If not set then
1662 it is checked whether the system has the GMP3 installed. If
1663 it has then the GMP won't be compiled (the system's headers
1664 and library is used), if it doesn't have it then the GMP is
1665 compiled in the SILC source tree.
1667 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Changed RSA private exponent generation to what PKCS #1
1670 suggests. We try to find the smallest possible d by doing
1671 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1672 not security fix but optimization.
1674 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Added new config entry [Identity] to fork the server and run
1677 it as specific user and group. A patch from Bostik.
1679 * Imported Dotconf configuration library into lib/dotconf.
1680 This will be used to create the SILC configuration files later.
1681 It will appear in the distsribution after this commit.
1683 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * A big code auditing weekend happening. Auditing code for
1686 obvious mistakes, bugs and errors. Also, removing any code
1689 Removed files for being obsolete:
1691 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1692 inline in the file lib/silcutil/silcbuffer.h)
1694 o lib/silcutil/silcbufutil.c (the header has inline versions)
1696 Changed code to fix possible error conditions:
1698 o The buffer formatting routines now check that the destination
1699 buffer really has enough space to add the data. This applies for
1700 both buffer formatting and unformatting
1701 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1702 unformatting was changed to accomodate following rules:
1703 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1704 sent to the function while XXX_*STRING will not allocate or copy
1705 the data into the buffer. Instead it sets the pointer from the
1706 buffer into the pointer sent as argument (XXX_*STRING used to
1707 require that the pointer must be allocated already). This change
1708 makes this whole thing a bit more consistent and more optimized
1709 (note that the data returned in the unformatting with XXX_*STRING
1710 must not be freed now). The routines return now -1 on error.
1712 o Tried to find all code that use buffer_format and buffer_unformat
1713 and added return value checking to prevent formatting and
1714 especially unformatting errors and possible subsequent fatal
1717 o Changed ske->x and ske->KEY to mallocated pointers in
1718 lib/silcske/silcske.h. Fixed possible data and memory leak.
1720 o Added return value checking to all *_parse* functions. Fixed
1721 many memory leaks as well.
1723 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1724 so that buffer overflows would not happen. All code now also
1725 checks the return value as it can fail.
1727 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Added reconnection support to server if the normal server looses
1730 its connection to the router (for example if router is rebooted).
1731 The server performs normal reconnection strategy implemented
1732 to the server. Affected file silcd/server.c.
1734 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Added new packet type SILC_PACKET_SET_MODE that is used to
1737 distribute the information about changed modes (for clients,
1738 channels and clients channel modes) to all routers in the
1739 network. Updated the protocol specification accordingly.
1741 Added functions into silcd/packet_send.c and
1742 silcd/packet_receive.c: silc_server_send_set_mode,
1743 silc_server_set_mode.
1745 Added new files silcmode.[ch] into lib/silccore that implements
1746 the encoding and decoding of Set Mode Payload. Added new type
1747 SilcSetModePayload. Moved the definitions of different modes
1748 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1750 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Oops, a little mistake in server's connection authentication
1753 protocol. The protocol is not ended with FAILURE but with
1754 SUCCESS if the authentication is Ok. :) Affected file is
1757 * Implemented NICK_CHANGE notify handling in server in the file
1758 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1759 the local clients on the channel. After the changing nickname
1760 in router environment snhould work and the [<unknown>] nickname
1761 should appear no more.
1763 The silc_server_replace_id function that receives the Replace ID
1764 payload now sends the NICK_CHANGE notify type also in the file
1765 silcd/packet_receive.c
1767 * Changed WHOIS and IDENTIFY command to support the maximum amount
1768 of arguments defined in protocol specs (3328 arguments). This
1769 fixed a bug that caused problems when there were more than three
1772 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Added extra parameter, command identifier, to the
1775 silc_client_send_command so that explicit command identifier
1778 Changed that ID list routines uses specific command identifier
1779 when sending WHOIS/IDENTIFY requests to the server so that they
1780 can be identified when the reply comes back.
1782 Affected files lib/silcclient/command.[ch],
1783 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1785 * Added `sender' argument to silc_server_packet_send_to_channel
1786 to indicaet the sender who originally sent the packet to us
1787 that we are now re-sending. Ignored if NULL. Affected file
1788 silcd/packet_send.[ch].
1790 * Added some server statistics support in silcd/server_internal.h
1791 SilcServerStatistics structure and around the server code. Also
1792 send some nice statistics information when client is connecting
1795 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Fixed channel ID decoding in server's JOIN command reply in
1798 silcd/command_reply.c
1800 * Fixed braodcasting of replace ID payload to not to send it if
1801 we are standalone server in silcd/packet_receive.c.
1803 * Fixed all channel message sending routines to not to send
1804 packets to clients that has router set, since they are routed
1805 separately in the same function earlier. Affects file
1806 silcd/packet_send.c and all channel packet sending functions.
1808 * In USERS reply, res_argv[i] are not allocated, the table
1809 is allocated. Thus changed that free the table, not its
1812 * In server's whois_check and identify_check if the client is
1813 locally connected do not send any WHOIS commands - they are not
1816 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Fixed some minor bugs in client when sending WHOIS command. The
1819 arguments was in wrong order.
1821 * Removed statis function add_to_channel from server in
1822 silcd/command.c that was previously used with the joining but
1825 * Tested USERS command in router environment successfully with two
1826 routers, two servers and two clients.
1828 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Reorganized the USERS command and command reply in client library
1831 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1832 When the command is given by user we register a pending command
1833 callback that will reprocess the command after the reply has been
1834 received from the server. When reprocessing the packet we then
1835 display the information. Thus, the USERS information is displayed
1836 now in the command callback instead of in the command reply
1837 callback. The processing of the command is same as previously
1838 when server has sent the command reply in the JOINing process.
1840 * Added to USERS command in silcd/command_reply.c to join the client,
1841 we didn't use to know about, to the channel after we've created
1842 a client entry for it. Also, for clienet we did know already still
1843 check whether it is on the channel or not and add it if not.
1845 * Removed silc_server_command_join_notify as the function and its
1848 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Changed the client's pending command handling to the same as the
1851 server's pending command handling. It is also now possible to
1852 execute command reply functions from other command reply
1853 function as the function callbacks for commands and command
1854 replies are one and same. The pending commands are not static
1855 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1856 in client connection context. Thus, pending commands are server
1857 connection specific as it is convenient.
1859 Changed the function silc_client_command_pending and
1860 silc_client_command_pending_del and added new function
1861 silc_client_command_pending_check. Removed the
1862 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1865 * Added cmd_ident, current command identifier, to the client
1866 connection context in lib/silcclient/client.h to keep track on
1867 command identifiers used in command sending. Client's command reply
1868 function handling now supports the mandatory command identifiers.
1870 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1871 funtions in client to fully support pending command callbacks.
1873 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1874 as one of the arguments to the application in the command reply
1877 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1878 before first releasing SILC but came back. Now it is removed again
1879 and should come back nomore. The FORWARDED flag was used only
1880 by the JOINing procedure by forwarding the command packet to router.
1881 Now, the JOINing procedure has been changed to more generic (due
1882 to various router environment issues) and FORWARDED is not needed
1883 anymore for anything. The protocol specification is yet to be
1886 Now, removed silc_server_packet_forward from server and the flag
1887 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1889 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * Renamed NAMES command to USERS command. The NAMES was named that
1892 due to historical reasons. Now it is renamed. Also, rewrote
1893 parts of the USERS command. The nickname list is not sent anymore
1894 by the server. Only Client ID and mode lists are sent in the USERS
1895 command. Changed this also to the protocol specification.
1897 The client now resolves the names and stuff after it receives
1898 the USERS list from the server when joining to the channel.
1900 * WHOIS and IDENTIFY commands has been changed to support multiple
1901 Client ID's per command. One can now search for multiple users
1902 in the network by sending only one WHOIS or IDENTIFY command.
1903 Changed the code and the protocol specifications.
1905 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1906 uses silc_server_command_whois_parse to parse the request. */
1908 * If normal server, do not parse the WHOIS and IDENTIFY requests
1909 before sending it to the router. Saves some time.
1911 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Fixed JOIN command on client library. Wrong number of arguments
1914 used to crash the client.
1916 * Added silc_server_channel_has_global function to check whether
1917 channel has global users or not.
1919 * Added silc_server_channel_has_local function to check whether channel
1920 has locally connected clients on the channel.
1922 * The silc_server_remove_from_one_channel now checks whether the
1923 channel has global users or not after given client was removed from
1924 the channel. It also checks whether the channel has local clients
1925 on the channel anymore. If it does not have then the channel entry
1926 is removed as it is not needed anymore.
1928 * The silc_server_notify now checks on JOIN notify whether the joining
1929 client is one of locally connected or global. If it is global then
1930 the channel has now global users on the channel and that is marked
1931 to the channel entry. Also, it now saves the global client to
1932 global list who is joining and JOINs it to the channel. This is
1933 for normal server, that is.
1935 Changed silc_server_send_notify_on_channel,
1936 silc_server_packet_relay_to_channel and
1937 silc_server_packet_send_to_channel check if we are normal server
1938 and client has router set (ie. global client) do not send the
1939 message to that client, as it is already routed to our router.
1941 * Implemented LEAVE notify type handling in silc_server_notify
1944 * Tested LEAVE command in router environment successfully. Tested
1945 with two routers, two servers and two clients.
1949 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1951 * Implemented SIGNOFF notify type handling in silc_server_notify
1954 * silc_server_remove_id now removes the client entry from all channels
1955 it has joined and thusly sends SIGNOFF notify type.
1957 * Rewrote the NAMES list generation in server by removing two excess
1958 loops. The lists are created now inside one loop.
1960 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * silc_server_remove_channel_user checks now also global list
1963 for channel and client.
1965 * silc_server_new_channel_user checks now both local and global
1966 list for channel and client. Fixed a bug in client id decoding.
1967 Used to decode wrong buffer.
1969 * silc_server_channel_message checks now both local and global
1970 list for channel entry.
1972 * Tested channel joining (hence JOIN) in router environment
1973 successfully. Tested with two routers, two servers and two
1976 * Tested channel message sending in router environment successfully.
1978 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Added silc_server_save_channel_key into server.[ch] to save the
1981 received channel key in Channel Key payload processing. It is
1982 also used in JOIN command reply handling.
1984 Equivalent function silc_client_save_channel_key added into
1985 client.[ch] into client library.
1987 * Changed JOIN command reply to send information whether the channel
1988 was created or not (is existing already) and the channel key
1989 payload. Changed protocol specs accordingly.
1991 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1992 the request was sent by ID and not by nickname. Crashed on
1995 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1998 now correctly save the received data.
2000 * silc_server_free_sock_user_data now notifies routers in the
2001 network about entities leaving the network.
2003 At the same time implemented functions silc_server_remove_id
2004 and silc_server_send_remove_id to receive and send REMOVE_ID
2005 packets. The packet is used to notify routers in the network
2006 about leaving entities. The ID removed will become invalid in
2009 * Added function silc_idlist_del_server into server. Removes and
2010 free's server entry from ID list.
2012 * silc_server_private_message function now checks, if we are router,
2013 that the destination ID really is valid ID, naturally.
2015 * In router when NEW_ID packet is received (for new client) the
2016 hash of the Client ID is saved in the ID Cache but the
2017 client->nickname is set to NULL, instead of putting the hash
2020 IDENTIFY command now also checks that client->nickname must be
2021 valid. If it is not if will request the data from the server who
2022 owns the client. Added new function
2023 silc_server_command_identify_check.
2025 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2026 to set the command to already allocated Command Payload.
2028 * Tested private message sending in router environment with two
2029 routers, two servers and two clients. Fixed minor bugs and now
2032 * Fixed segfault from client's NAMES command. Used to crash if
2035 * Forwarded packets must not be routed even if it is not destined
2036 to the receiver. Changed server code comply with this.
2038 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Added `require_reverse_mapping' boolean value to ServerParams
2041 structure. If TRUE (not default) the server will require that
2042 the connecting host has fully qualified domain name.
2044 If the reverse mapping is not required and hostname could not be
2045 found the IP address is used as hostname.
2047 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Implemented version string checking to both client and server.
2050 The check is incomplete currently due to the abnormal version
2051 strings used in development version of SILC.
2053 * Changed all command functions in server to use the new
2056 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Changed char *data to unsigned char *data in ID Cache system to
2059 support binary data as ID Cache data. Changed code to support
2060 binary data in lib/silccore/idcache.c.
2062 * Renamed silc_server_packet_relay_command_reply to
2063 silc_server_command_reply as it is normal packet receiving
2064 function. Rewrote the function to accept command replys for
2065 servers and not only for clients.
2067 * Mark remote router always as registered server if we are connecting
2068 to it. Otherwise, commands sent by the router to us are ignored.
2070 * All ID List find routines now returns the ID Cache Entry pointer
2071 as well if requested.
2073 * WHOIS command works now in router environment, tested with two
2074 routers, two servers and two clients.
2076 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2077 in router environment (as it is almost equivalent to WHOIS) but
2078 hasn't been tested thoroughly. Added new functions:
2080 silc_server_command_identify_parse
2081 silc_server_command_identify_send_reply
2082 silc_server_command_identify_from_client
2083 silc_server_command_identify_from_server
2085 * Disabled route cache adding because adding two different ID's with
2086 same IP replaces the old cache entry thus giving wrong route.
2087 The entry->router->connection is always the fastest route anyway
2088 so route cache may not be needed. Of course, new routes maybe
2089 established after receiving the ID when the entry->router->connection
2090 might not be anymore the most optimal.
2092 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Add route cache for received ID for fast routing.
2096 * Added silc_server_packet_route to route received packet on router
2097 that is not destined to us.
2099 * Renamed silc_server_get_route to silc_server_route_get.
2101 * Added id_string and id_string_len fields into SilcServer to
2102 include encoded ServerID for fast comparing without excess
2103 encoding of the ID's.
2105 * Cleaned up WHOIS command on server side. Added following static
2108 silc_server_command_whois_parse
2109 silc_server_command_whois_check
2110 silc_server_command_whois_send_reply
2111 silc_server_command_whois_from_client
2112 silc_server_command_whois_from_server
2114 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2115 arguments in command replies. All command functions should be
2116 updated to use this macro.
2118 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Minor typo fixes on command reply handling on server.
2122 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Added silc_server_command_add_to_channel internal routine to add
2125 the client to the channel after router has created the channel and
2126 sent command reply to the server.
2128 * Added generic silc_server_send_command to send any command from
2131 * Use static buffer with ID rendering instead of duplicating data.
2133 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Fixed a channel user mode bug when joining to a channel server gave
2136 everybody channel founder rights, oops.
2138 * We mark ourselves as the router of the incoming server connection
2139 if we are router ourselves. This way we can check in some packet
2140 sending functions whether it is locally connected server. For
2141 incoming router connections we put NULL.
2143 * For router sending packets locally means now always sending the
2144 packet cell wide; to local clients and local servers. For normal
2145 server sending packet locally means sending it to only local
2148 * Fixed the JOIN command to really work in router environment. If the
2149 channel is created it is always created by the router. Router is
2150 also responsible of making the initial joining to the channel,
2151 sending JOIN notify to the sending server and distributing
2152 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2153 does not exist server doesn't do anything else but forward the
2154 command to the router which performs everything.
2156 * Added silc_server_send_channel_key function to send the Channel Key
2159 * Added silc_server_create_channel_key to create new channel key. The
2160 channel key is now re-generated everytime someone joins or leaves
2161 a channel, as protocol dictates. Note: channel->key_len is the
2164 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2167 packet_receive.[ch] to separate packet sending and receiving
2168 routines. The server.[ch] now includes everything else including
2169 actual packet processing (writing and reading data) and other
2172 Renamed silc_server_private_message_send_internal to
2173 silc_server_send_private_message. The routine is still though
2174 used only to relay private messages as server does not send
2175 private messages itself.
2177 Renamed silc_server_new_channel to silc_server_create_new_channel
2178 and added new function sicl_server_new_channel that handles the
2179 incoming New Channel packet. Added also new sending function
2180 silc_server_send_new_channel to send New Channel Payload.
2182 * Added new function silc_server_notify to process incoming notify
2183 packet to the server/router. Server may then relay the notify
2184 to clients if needed.
2186 * Added new function silc_server_new_channel_user to process incoming
2187 New Channel User packet. Router will redistribute the packet and
2188 send JOIN notify to its local clients and locally connected servers
2189 if needed. Normal server will send JOIN notify to its local client
2190 on same channel when received this packet. Added also corresponding
2191 sending function silc_server_send_new_channel_user to sent the
2194 * Added boolean route argument to send_notif_to_channel and
2195 packet_send_to_channel functions to attempt to route the packet
2196 if it is TRUE and send only locally if it is FALSE.
2198 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * silc_server_replace_id now broadcasts the received replace ID
2201 packet if it is not broadcast packet already. The router must
2202 broadcast to inform other routers about changed ID.
2204 * Added backpointer to server's router into SilcServer context in
2205 silcd/server_internal.h.
2207 * Fixed silc_server_packet_broadcast to send correct broadcast
2210 * The channel key is now distributed to the local client as soon
2211 as it is received from the router (in router environment) so that
2212 no other packet may be sent for the channel until client has
2215 * silc_server_remove_channel_user now broadcasts the received
2216 Remove Channel User packet if it is not broadcast packet already.
2217 The router must broadcast to inform other routers about removed
2220 * Added users field into SilcPacketContext that is a reference count
2221 of the context. One can increase the reference count by calling
2222 silc_packet_context_dup which is now changed to just increase the
2223 reference count instead of duplicating the data. The reference
2224 count is decresed by calling silc_packet_context_free that will
2225 free the data after the reference count hits zero.
2227 For now on the packet context and everything allocated into it
2228 (including the raw packet from network) must be freed by calling
2229 the new silc_packet_context_free function. Added also new function
2230 silc_packet_context_alloc that must be used now to allocate the
2231 context. This also means that if a routine is asynchronous from
2232 silc_[client/server]_packet_parse_type the packet context must
2233 be duplicated by calling silc_packet_context_dup. Otherwise it
2234 gets free'd after silc_[client/server]_packet_parse_type returns.
2235 Also, one must remember that if packet is duplicated then its
2236 reference count must be decresed by calling the free function as
2237 many times as it was duplicated.
2239 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2240 from both client and server.
2242 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Made joining to a channel working in router environment.
2246 * Cleaned up JOIN command on server side and create function
2247 silc_server_command_join_channel internal routine to make the
2250 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2252 * Changed silc_command_pending list to SilcDList. Also, added
2253 `ident' field to SilcServerCommandPending structure to identify
2254 the reply and to call correct callback.
2256 Added silc_server_command_pending_check function to replace the
2257 corresnponding macro. The silc_command_pending list is not
2260 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2261 to set identifier to previously allocated Command Payload. It
2262 is used to set identifier for command when resending Command
2265 * Added silc_command_payload_encode_payload to encode Command
2266 Payload buffer from SilcCommandPayload structure.
2268 * Added silc_argument_payload_encode_payload to encode Argument
2269 payload buffer from SilcArgumentPayload structure.
2271 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Changed WHOIS command to support router connection on server side.
2274 The whois request is always sent to router unless the server is
2275 standalone server. After server has received the reply from the
2276 router will it send the reply to the client.
2278 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2279 broadcast received broadcast packet. The function is used only
2280 by router. The broadcast packet is always sent to the router's
2283 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2284 render given ID to printable string, for log files for example.
2286 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Made basic router to router connections working. At least they
2289 can now connect to each other but nothing really works the way
2290 they are supposed - yet.
2292 * Added new initiator token to RouterConnection configuration
2293 file in silcd/serverconfig.[ch]. It is used to tell whether we
2294 are the initiator to the remote router or whether we'll expect
2295 the other end to connect.
2297 * Moved registering of listener task to silc_server_init, hence
2298 the server starts listenning as soon as it is run, even if it
2299 does not have connections to other routers. Let's see how well
2302 * Changed default connection retry timeouts for more suitable in
2305 * Removed cipher and such arguments from silc_idlist_add_client
2306 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2307 Added new function silc_idlist_add_data to add the keys and stuff
2310 * Added SilcIDListData structure and added it to SilcClientEntry
2311 and SilcServerEntry as their first field in the structure. This
2312 way we can explicitly cast the ID entries to the SilcIDListData
2313 structure and get common data for the entries. In past, we had
2314 to first check what type of connection it is and then cast it to
2315 correct ID entry type. Now, we can directly cast the opaque
2316 pointer to the SilcIDListData (no matter what ID entry it actually
2317 is) and get the data needed.
2319 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2321 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2322 in some circumstances even if threre were timeout tasks, though not
2323 IO tasks, but tasks anyway. Now fixed.
2325 * Defined SilcServerConnection structure to hold connection specific
2326 stuff about directly connected servers and routers. The definition
2327 is currently in silcd/server_internal.h. I thought about having
2328 a bit more important role fro this struct but for now it is used
2329 only when connecting to other server (or router actually).
2331 * Added connecting retry support in server when connecting to
2332 router(s). The retry feature implement exponential backoff
2333 algorithm. Also, added SilcServerParams structure to hold default
2334 parameters for server. For now, it include these retry settings
2335 and are hard coded. After server is moded to be as Silc Server
2336 Library this structure will be more important.
2338 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Changed client librarys channel->clients table to SilcList and
2341 changed code accordingly.
2343 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Changed client's channel table to SilcList and changed code
2346 accordingly. Also changed SilcChannelClientEntry to include back-
2347 pointer to the channel so that client entry can use that structure
2348 as list as well and we have fast cross-reference to the channel.
2349 This change dramatically decreased the complexity of channel
2350 handling with client entry and vice versa (removed one extra
2351 loop when searching for channel entry from many functions).
2353 * Changed server->sim from table to SilcDList and changed code
2356 * NAMES command can now be used from user interface. It will show
2357 the user list on the channel, neatly.
2359 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2360 Code now saves realname of the user if it becomes available.
2362 * Renamed configure.in to configure.in.pre and made ./prepare
2363 script to automatically add correct version string to
2364 configure.in which it creates from configure.in.pre.
2366 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * NAMES command reply now shows users mode with the nickname when
2371 * Moved silc_client_ch[u]mode[_char] functions from
2372 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2373 place sucks, they are utility functions and should be in some
2376 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2378 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2381 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Added TRQ (efficient deque and list library) into lib/trq. This is
2386 a very good list library that is currently used in the SILC. Defined
2387 SilcList API over the library because I didn't like the API very
2388 much. See lib/trq/silclist.h for the API and examples of how to
2389 use the API. Fixed various places in the code to use the new
2390 SilcList API. The SilcList is meant for lists that has a structure
2391 already defined as a list. It is not suitable to add just some
2392 context to the list (in TRQ, the context is the list actually).
2394 So, I defined SilcDList that can be used for the purpose where
2395 predefined list structure does not exit. This can be used as
2396 such list. Now some context just can be added to the SilcDList.
2397 Currently this list is not used in the SILC just yet, though there
2398 are a lot places where this can replace dynamically allocated
2399 tables and I will fix these places, later, to use SilcDList.
2400 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2401 and use TRQ internally).
2403 Also fixed some annoying warning messages that the original TRQ
2404 code generated. Also minor changes to TRQ's Makefile.in.
2406 * Added support for querying by Client ID to both WHOIS and
2407 IDENTIFY commands into server, as required by the protocol.
2409 * Removed method function pointers from SilcBuffer structure. They
2410 weren't used to anything and just increased the context size for
2411 no good reason. This change also made silc_buffer_alloc and
2412 silc_buffer_free functions inline functions.
2414 * Disabled command flooding detection support until it's fixed so
2415 that it accepts commands in but does not execute them more than once
2418 * Added silc_net_localhost(), to return local hostname, into
2419 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2420 that must be initialized before calling silc_client_init.
2422 * Added new function: silc_server_send_notify_on_channels to send
2423 notify messages to all channels client has joined. It is assured
2424 that the message is sent only once per client.
2426 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2427 lib/silcutil/silcutil.[ch] as silc_format function. The new
2428 function is generic and is used by server as well, not only by
2429 the logging routines.
2431 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2432 the provided version string was not acceptable. Added new function:
2433 silc_ske_check_version into lib/silcske/silcske.h. The function
2434 must be implemented by the application (client or server) and it
2435 does not reside in the SKE library. The function checks the version
2436 string remote end sent.
2438 * Added back pointers (to opaque context and to SilcSocketConnection)
2439 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2441 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2442 duplicate packet context structure.
2444 * Changed `notify' client operation to send same arguments as client
2445 receives from server except for ID's. ID's are mapped to correct
2446 ID entry and that is returned. Also, if channel entry is not sent
2447 by server but the notify is for channel the channel entry is sent
2448 to application (otherwise application doesn't know that it is for
2449 channel (library gets it from packet's Destination ID)).
2451 * Added silc_client_remove_from_channels into client library to
2452 remove a client from all channels it has joined to. Used when
2453 received SIGNOFF notify from server. Added also new function
2454 silc_client_replace_from_channels to replace old ID entry with
2455 new ID entry on all channels. Used when received NICK_CHANGE
2458 * Fixed ID Cache list handling in silc_idlist_get_client in
2459 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2460 to get (or query) client by ID.
2462 * Updated TODO list.
2464 * Added connection authentication status message defined by the
2465 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2466 support for these into the code in client and server side.
2468 * Added generic function silc_client_send_command to send any command
2469 with variable argument list. Application should use this function
2470 to send commands if the command functions provided by the library
2471 does not suite for the application's user interface needs.
2473 * Added new `failure' client operation. Application is notified about
2474 received failure packet if client is executing a protocol. In this
2475 case the protocol's execution has failed.
2477 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2478 is required by the protocol.
2480 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2481 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2484 * Added status flag to SilcSKE object to indicate realtime status
2485 of the SKE protocol.
2487 * Application receives now exactly same command reply arguments as
2488 the library receives from server. However, if ID is received the
2489 corresponding ID entry is returned to the application (eg. Client
2490 ID is mapped to correct SilcClientEntry entry and that is returned).
2491 Changed command_reply client operation due to this change.
2493 * Changed all ID's in commands and in command replys as ID Payloads.
2494 Change affected both client and server side codes.
2496 All ID's sent in SILC network (with execption of ID's in SILC
2497 Packet header) are sent in ID Payload to support variable length
2500 * Server now notifies nick changes and notifies all clients on
2501 the channels about the new nickname (about the new Client ID,
2504 * Implemented CMODE command to change channel modes. Supports all
2505 channel modes defined by the protocol specs except ban and invite
2506 lists. (Also, private channel key mode is supported but support for
2507 setting private channel key in client is missing, thus, this mode
2508 has no effect on client side (except that server requires that the
2509 client uses private channel key and normal channel traffic does not
2512 Also, invite mode works per se, but INVITE command does not work
2513 yet correctly, so you can set channel as invite only channel but
2514 inviting clients to the channel does not work (it is yet to be
2515 thought what's the best way to do it).
2517 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2518 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2519 Implemented CUMODE command to change user's mode on the channel.
2520 Supports all modes defined by the protocol specs.
2522 * Added NAMES command reply to return users modes on the channel.
2524 * Removed unnecessary and slow ciphers from lib/silccrypt.
2526 * Set SO_KEEPALIVE option to connection sockets by default.
2528 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2530 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2531 redefined the Notify Payload into protocol specs.
2533 * Added silc_id_payload_parse_id to get ID directly from raw
2536 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2539 accept searching by Client ID as well.
2541 * Added support for LEAVE and SIGNOFF notify types in client library.
2543 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2544 to parse ID Payload from raw data.
2546 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Added flags parameter into silc_ske_assemble_security_properties
2549 function in lib/silcske/silcske.[ch].
2551 * Changed notify client operation to fit better for notify messages
2552 sent by server. The notify payload received from server is now
2553 passed to the application (after parsing it to SilcNotifyPayload).
2554 It is application's responsibility to retrieve the arguments
2555 from the payload and show the message the way it wants. The message
2556 sent by server is implementation specific.
2558 * Changed public keys to comply with the protocol specification.
2559 Old public keys are not supported anymore and are not compatible.
2561 * Removed nickname from Channel Payload as the latest draft removed
2562 it. The client must resolve the nickname from the NAMES command
2563 reply received when it joined the channel.
2565 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2567 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Fixed some errors in protocol specification drafts.
2571 * Created lib/silccore/silcnotify.c to implement Notify Payload
2572 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2573 generic payloads described by protocol specifications. The file
2574 includes implementations for ID Payload and Argument Payload.
2576 * Changed Command Payload implementation to use the new Argument
2577 Payload. Changed command_xxxx_payload to command_payload_xxxx
2578 to comply with SILC coding conventions.
2580 * Added suppport for Argument Payload handling in Notify Payload
2581 implementation as protocol requires it. Added the new support
2582 into server and client lib as well.
2584 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added support for multiple nicknames on same channel. [n] is
2587 added locally to the nickname if there are more than one same
2588 nicknames on the channel.
2590 * Server now sends all nicknames that matched WHOIS request.
2591 Client also shows the list received from server.
2593 * Added TOPIC command to client side. User can now set and show
2594 current topic on channel.
2596 * Added MOTD command to client and server. Also, server sends the
2597 motd when client connects to the server.
2599 * Changed version strings to comply ISO 8601.
2601 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Fixed protocol error handling in client library. It should now
2604 cope even if the SKE fails for some reason.
2606 * Made new protocol specification drafts for submitting to IETF.
2608 * Implemented TOPIC command to server in silcd/command.c.
2610 * Added two new notify types into lib/silccore/silcnotify.h:
2611 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2612 notify nickname change and topic setting/change on a channel.
2614 * API change of command_reply operation in client library. The
2615 application gets now the status type received from server as well.
2617 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2621 * Cras fixed and optimized the packet handling even further and
2622 it should work now. Minor change to the prototype of function
2623 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2625 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Added new function into lib/silcutil/silcschedule.[ch]:
2628 silc_schedule_with_fd to select() a specified fd. The function
2629 returns after timeout expires or data arrives or goes. The
2630 function is used by packet routines to wait that all data is
2631 received from network.
2633 * Fixed data reading from network in lib/silccore/silcpacket.c.
2634 The code now assures that all data is read from the fd and then
2635 continues packet processing. This was a bug fix since the code
2636 used to drop some data in some circumstances.
2638 * Added new function into lib/silcclient/client.[ch]:
2639 silc_client_start_key_exchange to start key exchange after
2640 connection has been established to server. The code internally
2641 now uses this funtion but its main purpose was to provide it
2642 for applications that perform their own connecting. After
2643 application has created a connection it merely calls this
2644 function to start the key exchange between client and server.
2645 The library takes care of everything else after that.
2647 Updated also lib/silcclient/README to explain the usage of
2650 * Do not send to application information that connection has
2651 been established. Application gets notified it by connect
2654 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Applied cras's patch to add silc_schedule_one function. The
2657 function runs scheduler once and returns.
2659 * Fixed the scheduler after cras messed it up. The timeout
2660 handling works now as it's supposed to work.
2662 * Added into lib/silccore/ silcnotify.h to include notify
2663 message types support. Changed silc_server_send_notify*
2664 functions, in server.[ch], to support those new notify types.
2665 Added the support for the notify types into client library,
2666 as well. Added new notify client operation into ops.h in
2669 * Changed silc_server_packet_send_to_channel to send normal
2670 packets instead of just channel message packets. The function
2671 is now used to send the notify packets to channels. It is not
2672 used to send channel message packets anymore, as server never
2675 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2676 va_arg()s as it seems to require it nowadays. I guess, if SILC
2677 is compiled with older va_arg() the new code should work anyway.
2679 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Splitted core library. Core library (lib/silccore) includes
2682 now only SILC protocol specific core (and common) components.
2683 Created new utility library (lib/silcutil) that includes more
2684 generic purpose stuff. The stuff for util library was taken
2685 from the old core library. This was minor and easy split.
2687 * Created SILC Client Library (lib/silcclient) that includes
2688 implementation of the SILC client without user interface. This
2689 was major move from silc/ directory. The code has been changed
2690 so that it is transparent towards the user interface. The
2691 silc/ directory includes now the same user interface as before
2692 and it uses the new client library. Read lib/silcclient/README.
2693 Basicly, the client library performs everything else related
2694 to SILC except user interface handling. Also, configuration
2695 files are considered to be part of user interface and library
2696 does not handle them.
2698 This change also changed a lot of structures, function naming etc.
2699 Most important change was that SilcClientWindow object was
2700 renamed to SilcClientConnection in the client library. Created
2701 also new file lib/silcclient/ops.h. Also added new files
2702 silc/local_command.[ch] and silc/client_ops.[ch].
2704 All these changes were made to make it easier for user interface
2705 designers to create what ever user interface for the SILC client
2708 It is also expected that the server will be moved to lib
2709 directory as well and SILC Server Library will be created;
2710 sometimes in the future.
2712 * Removed Local commands from lib/silccore/silccommand.h as
2713 they are application specific and new client library does not
2714 handle any of those anymore.
2716 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2717 old client implementation in silc/.
2719 * Added support for callback functions in SILC_LOG_* macros.
2720 Application can now set its own callbacks that will be called
2721 instead of using the default functions that will always print
2722 the debug messages to stderr (or stdout). Also, debugging can
2723 now be disabled by setting silc_debug to FALSE and re-enabled by
2724 setting it to TRUE. Note, that logging will still work even
2725 if debugging is disabled.
2727 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2728 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2729 silc_log_reset_debug_callbacks.
2731 * To enable debugging in silc client one must give now -d
2732 option on command line.
2734 * Changed silc_schedule_init to automatically allocate task queues
2735 if they are not allocated before calling it.
2737 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added GMP 3.1 into math library.
2741 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2743 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2744 a channel in SILC network. The packet is used by servers and
2745 routers to notify other routers that user has left a channel.
2746 This little feature was missing until now. Added the feature
2747 to protocol specification as well.
2749 Added functions: silc_server_send_remove_channel_user and
2750 silc_server_remove_channel_user into server.[ch].
2752 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2753 lib/silccore/silcpacket.h. However, they are not implemented
2756 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed joining to a channel and sending channel messages
2759 between server and router. The channel message sending should
2760 now work inside a cell.
2762 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Fixed the private message sending between server and router.
2765 The private message sending should now work inside a cell.
2767 * Added silc_server_replace_id into server.[ch] to replace
2768 existing ID in the SILC network.
2770 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2771 and silc_idlist_replace_server_id into idlist.[ch] in server.
2773 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Fixed the server to server connections. Server can again now
2776 connect to router. Router to router connections probably does
2779 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Added dynamic protocol registering support. Now protocols can
2782 registered and unregistered on the fly. Patch by cras.
2784 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Added lib/contrib directory to hold routines that some platforms
2787 don't have but are needed by SILC.
2789 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2790 into lin/contrib to provide getopt() and getopt_long() for
2791 those who don't have it.
2793 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Added AWAY command to client. When away message is set and
2796 client receives a private message packet the client automatically

2799 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2800 bug seemed to be the cause of recent problems when compiling
2803 * Added version detection support to SKE protocol specification
2804 and added the new changes to the SKE implementation as well.
2805 There were other minor changes in the SKE protocol as well.
2807 Many changes in lib/silcske/silcske.[ch] and in
2808 lib/silcske/payload.[ch].
2810 * Added ^U functionality, clear input line. Patch from cras.
2812 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Mainly small bugfixes on core library. Fixed some debugging
2815 logging and buffer overflow in silclog.c.
2817 * Updated config.sub and config.guess on the distribution tree.
2819 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * Added command lagging support in server. Client may execute
2822 commands now only once in two seconds.
2824 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Optimized packet reception. MAC computation and checking is now
2827 also more optimized. A lot previously duplicated code is now
2828 used as generic by both client and server.
2830 * Fixed key pair generation in clientutil.c
2832 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Added into lib/silccore/silcbufutil.[ch] new function;
2835 silc_buffer_realloc.
2837 * Moved generic packet sending/encryption functions to
2838 lib/silccore/silcpacket.[ch] from client and server. Some
2839 rewriting of the functions.
2841 * Moved all generic packet reception/decryption functions to
2842 lib/silccore/silcpacket.[ch] from client and server. The
2843 packet processing is now much cleaner in both client and server.
2844 These were major changes in both client and server.
2846 * Created many common functions in server to do packet sending.
2847 Previously code were duplicated a lot, this has been removed
2850 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Rewrote major parts of the ID cache system. Don't know
2853 whether it is better now or not but at least the API is more
2856 * Major rewrite on ID cache stuff on client because of the ID
2857 cache API changes. Added idlist.c to client.
2859 * Also major rewrite on ID cache stuff on server as well.
2860 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2861 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2862 in hand, instead they are all put into the ID cache system now.
2863 All server_idlist_* routines uses ID cache now instead of
2864 traversing its own lists (those lists does not exist anymore).
2865 SilcIDList though still exists. Also, SilcXXXEntry's are
2868 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Finally made the SKE implementation compliant to the protocol
2871 specification. All mp integers are now binary encoded as
2872 opposed being HEX encoded.
2874 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2877 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2878 functions: silc_[encode/decode]_pem. Also added function
2879 silc_encode_pem_file to PEM encode with newlines ('\n') for
2882 * SILC public keys are now encoded either PEM or binary. Same
2883 option is for private keys as well. By default private keys
2884 are binary encoded and public keys PEM encoded. Silly HEX
2885 encoding were removed.
2887 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2888 function to create fingerprints.
2890 * Fixed a bug in SHA1; does not change the original data anymore.
2892 * Partly implemented INFO command on client and server side.
2893 Fixed CLEAR command. Changes to SERVER command; show current
2894 server(s) when giving command without arguments. Added
2895 VERSION command to client.
2897 * Added check to server that unregistered connections cannot
2898 execute commands (unless it is specificly allowed).
2900 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Fixed screen refresh.
2904 * Fixed channel joining bug from client. On some circumstances
2905 client tried to join to a channel it had already joined.
2907 * Added public key verification process into client's protocol.c.
2908 The client now verifies the public key from user and saves
2909 it into ~./silc/serverkeys/ directory.
2911 Added into: clientutil.[ch]: silc_client_verify_server_key.
2913 * Changed SKE protocol's silc_ske_initiator_finish function
2914 to accept callback function that verifies the received public
2915 key. Removed old silc_ske_verify_public_key function.
2917 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2920 silc_pkcs_private_key[_data]_set.
2922 * Made the password and public authentication more cleaner in
2923 server's protocol.c.
2925 * Removed historic and obsolete protocol `channel_auth' from
2926 both client and server.
2928 * Removed wrong way of sending command status messages from
2929 server to client in server's command.c. The old way violated
2930 protocol specification.
2932 Changes to silccore/silccommand.[ch]: removed
2933 silc_command_encode_status_payload -> not needed anymore,
2934 changed silc_command_encode_payload_va to accept extra
2935 argument on variable argument list. The argument type must
2936 now be provided to the function. Also, added new function:
2937 silc_command_encode_reply_payload_va which is same as
2938 normal command_encode_payload_va except command status type
2939 is provided as extra argument.
2941 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Added ~./silc directory handling. The directory includes the
2944 public and private keys for the client.
2946 Added silc_client_check_silc_dir, silc_client_create_identifier
2947 and silc_client_load_keys.
2949 * Implemented SILC protocol compliant public key. Added public
2950 and private key saving to and loading from files.
2952 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2953 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2954 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2955 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2956 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2958 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2959 silc_pkcs_load_[public/private]_key.
2961 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Added silc_server_get_route (route.[ch]) to get connection
2964 data for the fastest route for given ID.
2966 * Implemented INVITE command on client and server. The command
2967 were re-defined in the SILC Protocol Specification and the
2968 implementation now complies with the specification.
2970 * Implemented PING command on client and server.
2972 * Implemented NAMES command on client and server. The server side
2973 supports currently only normal server not router server yet.
2974 Some changes to NAMES definition in SILC protocol specification.
2976 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Implemented LEAVE command on client and server.
2980 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2981 again. This change was made to the protocol as well. Server
2982 should not violate the protocol specification anymore.
2984 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2987 was tested. SOCKS4 was not but should work anyway.
