1 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new local command ME to the client. It is used to send
4 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5 some action. Affected file silc/local_command.[ch].
7 * Changed channel_message and private_message client operations
8 to deliver the message flags to the application. Added also
9 the `flags' arguments to the silc_client_send_channel_message
10 and silc_client_send_private_message functions. Affected file
13 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Redefined the Private Message Payload to support private message
16 keys and to support the new private message flags. Updated
17 the protocol specs. Flags makes it possible to have for example
20 * Added new type SilcPrivateMessagePayload and defined an API
21 for it in the lib/silcclient/silcprivate.[ch].
23 * Tested private message private keys successfully. Tested the
24 private message key set, unset and list commands with the new
27 * Redefined the Channel Message Payload to include the channel
28 message flags (equal with private message flags) to support
29 for example CTCP style messages.
31 * Defined some of the message (for channel and private message)
32 flags. Updated the protocol specs and added the flags to the
33 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
35 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
37 * Added SilcKeyAgreementStatus type to the key agreement routines
38 to indicate the current status and error if one occured.
39 The status types are defined in the lib/silcclient/silcapi.h.
41 * Added new local command KEY that is used to set and unset private
42 keys for channels, set and unset private keys for private messages
43 with remote clients and to send key agreement requests and
44 negotiate the key agreement protocol with remote client. The
45 key agreement is supported only to negotiate private message keys,
46 it currently cannot be used to negotiate private keys for channels,
47 as it is not convenient for that purpose.
49 * Fixed a minor pending callback setting bug in the function
50 silc_client_get_client_by_id_resolve, now the function works.
51 Affected file lib/silcclient/idlist.c.
53 * Added function silc_net_get_local_port to get local bound
54 port by socket. Added to lib/silcutil/silcnet.[ch].
56 * Added `sockets' and `sockets_count' fields to the SilcClient
57 object. They hold the sockets of the listenning sockets in
58 the client. Listenning sockets may be for example the key
59 agreement server. Affected file lib/silcclient/client.[ch].
60 Added functions the silc_client_add_socket and the
61 silc_client_del_socket. They are exported to the application
64 * Added ~./silc/clientkeys to support other client's public keys.
66 * Renamed verify_server_key client operation to verify_public_key
67 and added one argument to indicate the type of the connection
68 (server, client etc.).
70 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Added silc_server_connection_auth_request to handle the
73 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
74 silcd/packet_receive.[ch].
76 * Added silc_server_send_connection_auth_request into the
77 silcd/packet_send.c to send the connection auth request packet.
79 * Cleaned up the silcd/protocol.c a bit and fixed some memory
82 * Fixed the public key authentication in responder side in the
83 server. The `auth_data' pointer includes the SilcPublicKey
84 not the path to the public key. Affected file silcd/protocol.c.
86 * Implemented the public key authentication in the initiator side
87 in the server. Affected file silcd/protocol.c.
89 * Removed the [RedirectClient] config section from the server
90 configuration. Is not needed and I don't want to implement it.
92 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * Cleaned up the CMODE command in the server. It now works
95 correctly and supports all the modes defined in the protocol.
96 Affected file is silcd/command.c.
98 * Added `hmac_name' field to the SilcChannelEntry in the server
99 to hold the default HMAC of the channel. It can be set when
100 creating the channel (with JOIN command). Affected files
103 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
104 type to indicate the change of the current cipher and hmac
105 on the channel. Client can safely ignore the <cipher> argument
106 (if it chooses to do so) since the CHANNEL_KEY packet will
107 force the channel key change anyway. The <hmac> argument is
108 important since the client is responsible of setting the new
109 HMAC and the hmac key into use.
111 * Fixed the CMODE command in the client library as well.
113 * Tested CMODE command in router environment successfully.
115 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Show the version of the remote client (or server) when connecting
118 to the server. It is logged to the log file. Affected file
121 * Fixed the KILLED notify handling in the client library. The
122 client must be removed from all channels when receiving the
125 Also, do not remove the client entry when giving the KILL
126 command but when the KILLED notify is received.
128 * Removed silc_idlist_find_client_by_nickname from the server.
129 Not needed anymore. Affected files silcd/idlist.[ch].
131 * Implemented the CHANNEL_CHANGE notify type handling to the
132 server. Affected file silcd/server.c.
136 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

139 notify between routers.
141 * Implemented the INVITE command correctly to the server.
143 * Implemented the INVITE notify type handling in the server.
145 * Implemented the INVITE command to the client library and on the
148 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Added function silc_server_get_client_resolve to find the
151 client entry by ID from all ID lists and then resolve it
152 (using WHOIS) if it cannot be found. Affected file is
155 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Implemented the BAN command to the client library.
159 * The JOIN command in the server now checks the invite list
162 * Changed the silc_command_reply_payload_encode_va and the
163 silc_command_payload_encode_va to support that if argument is
164 NULL it ignores and checks the next argument. Affected file
165 lib/silccore/silccommand.c.
167 * Added silc_server_send_notify_ban to send the BAN notify
168 type between routers.
170 * Chaned the silc_notify_payload_encode to support that if
171 argument is NULL it ignores and checks the next argument.
172 Affected file lib/silccore/silcnotify.c.
174 * Tested ban lists in router environment successfully.
176 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Implemented BAN command to the server, in silcd/command.[ch].
180 * Removed the BAN and INVITE_LIST modes from the CMODE command
183 * Added function silc_string_match to regex match two strings.
184 Affected files lib/silcutil/silcutil.[ch].
186 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Redefined parts of the SilcChannelEntry in the server to support
189 the new ban and invite lists.
191 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Redefined the INVITE command. The same command can be used to
194 invite individuals to the channel but also to manage the invite
195 list of the channel (to add to and remove from the invite list).
196 Updated the protocol specs.
198 * Added new command SILC_COMMAND_BAN that can be used to manage
199 the ban list of the channel. Updated the protocol specs.
201 * Removed the channel modes: the SILC_CMODE_BAN and the
202 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
203 in the CMODE command. The equivalent features are now available
204 using INVITE and BAN commands. Updated the protocol specs.
206 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
207 in the network about change in the current ban list. The notify
208 type is not used by the client.
210 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
211 support the invite lists.
213 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Added new function silc_string_regexify that converts string
216 including wildcard characters into regex string that can
217 be used by the GNU regex library. Added into the file
218 lib/silcutil/silcutil.[ch].
220 Added silc_string_regex_combine to combine to regex strings
221 into one so that they can be used as one regex string by
222 the GNU regex library. Added into the file
223 lib/silcutil/silcutil.[ch].
225 Added silc_string_regex_match to match two strings. It returns
226 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
228 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Imported GNU regex to the soruce tree into lib/contrib.
231 Fixed some compiler warning from the regex.c.
233 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Fixed MOTD command in the server to work in router environment.
237 * Fixed the MOTD command in the client library to support
238 the server argument in the command.
240 * Added `nickname_len' argument to the silc_idlist_add_client
241 in the server, as the `nickname' argument may be binary data
244 * Added silc_idlist_get_channels to return all channels from
247 * Implemented LIST command to the server. Affected file is
250 * Implemented the LIST command to the client library and on the
253 * Added [<user count>] argument to the LIST command reply.
254 With private channels the user count is not shown.
256 * Updated TODO and README.
258 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * The client entry's data.registered must be TRUE even with
261 global client entry on global client list. The data.registered
262 is used to check whether the client is anymore in the network,
263 for example with WHOWAS command so it must be valid.
265 * Fixed the WHOWAS command in the server. It now actually works
266 in router environment. Added function into silcd/command_reply.c
267 silc_server_command_reply_whowas_save.
269 * Added silc_idlist_purge function to the silcd/idlist.c
270 to periodically purge the ID Cache.
272 * Fixed INFO command in the server. It works now in router
273 environment. Added <server name> argument to the INFO command
274 reply. Updated the protocol specs.
276 * Fixed minor bug in silc_idcache_purge to not purge if the
277 expire value is zero.
279 * Fixed various bugs in WHOIS and IDENTIFY command handling as
280 they were buggy because of the WHOWAS information.
282 * Fixed local command MSG to handle the async resolving of
283 the remote client properly. It used to fail the first MSG.
284 Affected file silc/local_command.c.
286 * Added `data_len' field to SilcIDCache context.
288 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Update TODO. Todo in commands in the server.
292 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
295 used by routers as broadcast packet to inform other routers
296 about the changed user mode.
298 Implemented the notify handling in the server. Affected file is
299 silcd/packet_receive.c. Added the function
300 silc_server_send_notify_umode to the silcd/packet_send.[ch].
302 * Added new generic Channel Payload and deprecated the New Channel
303 Payload. The New Channel Payload is now the generic Channel
306 * Added new argument `mode' to the silc_server_send_new_channel
307 as it is required in the Channel Payload now.
309 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
310 and created a new and real SilChannelPayload to represent the
311 new generic Channel Payload. Implemented the encode/decode
312 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
314 * Added silc_server_get_client_channel_list to return the list
315 of channels the client has joined for WHOIS command reply.
316 Affected file silcd/server.[ch].
318 * Implemented the channel list sending in the WHOIS command reply
319 in server and in the client.
321 Implemented the channel list displaying on the user interface
322 as well. Affected file silc/client_ops.c.
324 * Added silc_channel_payload_parse_list to parse list of Channel
325 Payloads. It returns SilcDList list of SilcChannelPayloads.
326 Client for example can use this function to parse the list of
327 channels it receives in the WHOIS command reply. The caller
328 must free the list by calling silc_channel_payload_list_free.
329 Affected files lib/silccore/silcchannel.[ch].
331 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Added one new argument <user mode> to the WHOIS command reply
334 to return the mode of the user in SILC. Updated the protocol
337 Implemented it to the server and client.
339 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Fixed the mode printing on the user interface on joining.
342 Affected file silc/client_ops.c.
344 * Implemented the UMODE command and user modes in general to the
345 client library and to the user interface.
347 * Implemented the UMODE command to the server.
349 * The server now sends UNKNOWN_COMMAND error status if client sends
350 unknown command. Affected file silcd/command.c.
352 * All server commands now handle the command identifier the right
353 way when sending the command reply to the client. The client can
354 use to identify the command replies with the identifier.
356 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added silc_server_get_client_route to resolve the route to
359 the client indicated by the client ID. Affected file is
362 * Added silc_server_relay_packet as general function to relay
363 packet to arbitrary destination. This deprecates functions
364 like _send_private_message_key, _relay_notify etc. Affected
365 file is silcd/packet_send.[ch].
367 Removed silc_server_send_key_agreement,
368 silc_server_send_private_message_key and
369 silc_server_packet_relay_notify functions from the file
370 silcd/packet_send.[ch].
374 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
375 server. Affected file silcd/packet_receive.[ch].
377 * Implemented the KILL command to the client. Implemented the
378 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
379 Affected files lib/silcclient/command[_reply].c and
380 lib/silcclient/client_notify.c. Implemented the KILL notify
381 printing in the user inteface.
383 * Fixed a lot silc_parse_nick memory leaks from the client
384 library in the file lib/silcclient/command.c.
386 * Changed the silc_server_send_notify_on_channels's `sender'
387 argument from SilcSocketConnection to SilcClientEntry to
388 check the sender as entry and not as connection object and not
389 to send to the client provided as argument. The affected file
390 is silcd/packet_send.[ch].
392 * The notify packets that are destined directly to the client used
393 to not to be processed by the server. Now changed that and the
394 server processes all notify packets. After relaying the packet
395 to the client the notify packet is processed in the server.
397 * The silc_server_free_client_data now checks whether there is
398 pending outgoing traffic for the client and purges the data to
399 the network before removing the client entry.
401 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
404 an client is killed from the SILC Network. Updated the protocol
407 Added new function silc_server_send_notify_killed to the
408 silcd/packet_send.[ch].
410 * Added function silc_server_packet_relay_notify to relay notify
411 packets that are destined directly to a client. In this case
412 the server does not process the notify packets but merely relays
413 it to the client. Affected file silcd/packet_send.[ch].
415 Added also silc_server_packet_process_relay_notify to check
416 whereto relay the notify. Affected file is
417 silcd/packet_receive.[ch].
419 * Implemented the KILL command to the server.
423 * Added the backup schema desgined last fall to the protocol
424 specs for everyone to see. The specification is in the
425 *-spec-xx.txt draft and the packet type definitions for the
426 backup routers is in *-pp-xx.txt draft. Thusly, added also
427 new packet type SILC_PACKET_CELL_ROUTERS.
429 * A big security problem in the implementation discovered. The
430 signoff of an client did not cause new channel key generation
431 which it of course should've done. The channel keys must be
432 always re-generated when client leaves (or signoffs) the channel.
433 The silc_server_remove_from_channels funtion now handles
434 the channel key re-generation.
436 * Added `sender' argument to the silc_server_send_notify_on_channels
437 to not to send the client provided as argument. Affected file
438 silcd/packet_send.[ch].
440 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Implemented OPER and SILCOPER commands into the server and
445 * Added silc_auth_verify and silc_auth_verify_data to verify
446 the authentication directly from the authentication payload.
447 It supports verifying both passphrase and public key based
448 authentication. Affected file lib/silccore/silcauth.[ch].
450 * Added `hash' field to the SilcIDListData structure. It is the
451 hash negotiated in the SKE protocol. Affected file is
454 * Slight redesigning of the SilcAuthPayload handling routines.
455 Do not send SilcPKCS but SilcPublicKey as argument.
457 * Implemented the public key authentication support to the
458 serverconfig. The public key is loaded from the provided path
459 and saved as authentication data to void * pointer. Thus,
460 changed the unsigned char *auth_data to void *auth_data;
462 * Fixed SHUTDOWN command to send the reply before the server
463 is shutdown. :) Affected file silcd/command.c.
465 * Fixed fatal bug in CONNECT command. The hostname was invalid
466 memory and server crashed. Affected file silcd/command.c.
468 * Fixed fatal bug in CLOSE command. The server_entry became
469 invalid but was referenced later in the command. Affected file
472 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Fixed fatal bug in failure packet handling. Server ignored
475 the failure and thus crashed when it came.
479 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
482 that the command may be executed only once in (about) 2 seconds.
483 The old SILC_CF_LAG flag is same but allows command bursts up
484 to five before limiting.
486 Added the support for CF_LAG and CF_LAG_STRICT flags to the
487 server code. Various commands now includes the CF_LAG_STRICT
488 flag to disallow any kind of miss-use of the command.
490 * Fixed the silc_buffer_unformat to not to allocate any data
491 if the length of the data is zero. It used to allocate the
492 length + 1. Affected file lib/silcutil/silcbuffmt.c.
494 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Changed the format of AdminConnection configuration section
497 in the server. Added username of the admin to the format.
498 Affected files silcd/serverconfig.[ch].
500 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
501 to return admin configuration data by host, username and/or
504 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Implemented WHOWAS command to the server. Added the functions:
508 silc_server_command_whowas_parse,
509 silc_server_command_whowas_send_reply,
510 silc_server_command_whowas_from_client and
511 silc_server_command_whowas_from_server
513 * Added <Client ID> argument to the WHOWAS command reply. Updated
514 the protocol specs accordingly.
516 * Implemented WHOWAS command and command_reply to the client
519 Implemented the WHOWAS printing on the user interface.
521 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Added new argument to the WHOWAS command reply, the real name.
524 It is an optional argument. Updated the protocol specs.
526 * Added SilcIDCacheDestructor callback that is registered when
527 the SilcIDCache is allocated. The callback is called when
528 an cache entry in the ID Cache expires, or is purged from the
529 cache. Added into lib/silccore/idcache.[ch].
531 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
532 to destruct the client entries when the cache entry expires.
533 Other ID Cache's in server and in the client library ignores
536 * If the ID Cache entry's `expire' field is zero then the entry
537 never expires. Added boolean `expire' argument to the
538 silc_idcache_add function in the lib/silccore/idcache.[ch].
539 If it is TRUE the default expiry value is used.
541 * Added silc_server_free_client_data_timeout that is registered
542 when client disconnects. By default for 5 minutes we preserve
543 the client entry for history - for WHOWAS command.
545 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * Added support to the server to enforce that commands are not
548 executed more than once in 2 seconds. If server receives
549 commands from client more frequently, timeout is registered
550 to process the commands. Affected file silcd/command.c.
551 Added new function silc_server_command_process_timeout.
553 * Changed NICK_NOTIFY handling in client library to check that
554 if the client's nickname was changed, so there is no need to
555 resolve anything from the server.
557 * Removed error printing from the WHOIS and IDENTIFY commands.
558 If error occurs then it is ignored silently in the client library.
559 The application, however, may map the received error to
560 human readable error string. The application currently maps
561 the NO_SUCH_NICKNAME error to string.
563 * Made the command status message public to the application. Moved
564 them from lib/silcclient/command_reply.c to
565 lib/silcclient/command_reply.h. The application can map the
566 received command status to the string with the
567 silc_client_command_status_message function.
569 * Added check to the server to check that client's ID is same
570 as the Source ID in the packet the client sent. They must
573 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Added dist-bzip hook to the Makefile.am to make bzip2
576 compressed distributions.
578 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
580 * Server now enforces the maximum length for the nickname and
581 the channel as protocol specification dictates. 128 bytes for
582 nickname and 256 bytes for channel name.
584 * Moved the WHOIS printing to the application. The client libary
585 does not print out the WHOIS information anymore, the application
586 must do it. Renamed silc_client_command_reply_whois_print to
587 the silc_client_command_reply_whois_save.
589 The client's idle time is also sent to the application now, and
590 the idle is shown on screen.
592 * Added silc_client_command_reply_identify_save to save the
593 received IDENTIFY entries.
595 * Do not check for channel private keys in message sending and
596 reception if the channel does not have the PRIVKEY mode set.
597 Affected file lib/silclient/client_channel.c.
599 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
602 just surfaced after chaning the JOIN procedure.
604 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Added silc_client_get_clients_by_list to get client entries
607 from Client ID list, that is returned for example by JOIN
608 and USERS command replies. The application should use this
609 function for example when JOIN command reply is received to
610 resolve the clients already on the channel (library does not
611 do that anymore as USERS command reply is not used in the JOIN
612 procedure anymore). Affected files lib/silcclient/silcapi.h and
613 lib/silcclient/idlist.c.
615 * JOIN command reply and USERS command reply returns now SilcBuffer
616 pointers instead of unsigned char pointers when returning
617 the client list and mode list.
619 * Added <Client ID> argument to the JOIN command reply, mainly
620 for the server to identify for which client the command was
621 originally sent. Updated protocol specs accordingly.
623 * Added SilcDlist private_key pointer to the SilcChannelEntry
624 in the client to support the channel private keys. Affected
625 file is lib/silcclient/idlist.h.
627 * Added SilcChannelPrivateKey argument to the function
628 silc_client_send_channel_message so that application can choose
629 to use specific private ke if it wants to. If it is not provided,
630 the normal channel key is used, unless private keys are set.
631 In this case the first (key that was added first) is used
632 as the encryption key.
634 * Implemented the support for channel private key handling.
635 Implemented the following functions:
637 silc_client_add_channel_private_key,
638 silc_client_del_channel_private_keys,
639 silc_client_del_channel_private_key,
640 silc_client_list_channel_private_keys and
641 silc_client_free_channel_private_keys
643 Affected file lib/silcclient/client_channel.c.
645 * Added the support for the private keys in the channel message
646 sending and encryption and in the message reception and
647 decryption. Affected funtions are
648 silc_client_send_channel_message and silc_client_channel_message.
650 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Added SKE's key verify callback to the client library's
653 KE protocol context. Affected files lib/silcclient/protocol.[ch].
655 * Removed the statement that server (or router) must send USERS
656 command reply when joining to the channel so that the client
657 knows who are on the channel. Instead, the client list and
658 client's mode list is now sent in the JOIN command reply to the
659 client who joined channel. This is better solution.
661 * Added function silc_server_get_users_on_channel and function
662 silc_server_save_users_on_channel to the silcd/server.[ch].
664 * Removed function silc_server_command_send_users from the
667 * Do not show topic on the client library anymore. The topic is
668 sent in the command reply notify to the application and the
669 application must show the topic now.
671 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Added client searching by nickname hash into the IDENTIFY and
674 WHOIS commands in the server as they were clearly missing from
675 them. Affected file is silcd/command.c.
677 * Fixed a bug in private message receiving in the client library.
678 The remote ID was freed and it wasn't supposed, now it is
681 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Minor fix to the channel payload; allocate the data area, as it
684 needs to be of specific length.
686 * If the key agreement port is zero then the operating
687 system will define the bound port. Affected files are
688 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
690 * Added new function silc_channel_payload_decrypt into the file
691 lib/silccore/silcchannel.[ch].
693 * Moved the channel message etc, check from silc_packet_decrypt
694 to applications. The library calls now a generic
695 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
696 when the packet is either normal or special. This was done to
697 allow more wide range of checking that was not allowed when
698 the code was in library. Now applications can do virtually any
699 checks to the packet and return to the library the decision how
700 the packet should be processed. Affected files are
701 lib/silccore/silcpacket.[ch].
703 Added silc_server_packet_decrypt_check to the server and
704 silc_client_packet_decrypt_check to the client library.
706 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
707 to send with specified source and destination information.
709 * Channel message delivery between routers was broken after the
710 channel key distribution was fixed earlier. The channel key
711 was used be to distributed to other routers as well which is not
712 allowed by the protocol. Now this is fixed and channel keys
713 really are cell specific and the channel message delivery between
714 routers comply with the protocol specification.
716 * Fixed various commands in server to check also the global list
717 for the channel entry and not just the local list. The affected
718 file silcd/command.c.
720 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Added assert()s to buffer formatting and unformatting routines
723 to assert (if --enable-debug) when error occurs. Affected
724 file: lib/silcutil/silcbuffmt.c.
726 * Changed to auto-reconnect to check whether the remote host is
727 router and register the re-connect timeout if it is. It used
728 to check that whether we are normal server, but router must do
729 auto-reconnect with another router as well. Affected file
732 * Removed the [<key len>] option from CMODE command as the cipher
733 name decides the key length, nowadays. See the defined ciphers
734 from the protocol specification.
736 * Added [<hmac>] option to the CMODE command to define the HMAC
737 for the channel. Added SILC_CMODE_HMAC channel mode.
739 * Added [<hmac>] option for the JOIN command so that user can
740 select which HMAC is used to compute the MACs of the channel
743 * Added Hmac field to the Channel Message Payload. The integrity
744 of plaintext channel messages are now protected by computing
745 MAC of the message and attaching the MAC to the payload. The
746 MAC is encrypted. Now, it is clear that this causes some
747 overhead to the size of the packet but rationale for this is that
748 now the receiver can verify whether the channel message decrypted
749 correctly and also when private keys are set for the channel the
750 receiver can decrypt the packet with several keys and check from
751 the MAC which key decrypted the message correctly.
753 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
754 lib/silccrypt/silccipher.[ch].
756 * Added silc_hash_len to return the digest length into the
757 lib/silcrypt/silchash.[ch].
759 * Rewrote parts of Silc Channel Payload interface in the
760 lib/silccore/silcchannel.[ch]. The encode function now also
761 encrypts the packet and parse function decrypts it.
763 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Fixed a minor formatting bug in the SKE's key material processing.
766 It actually might have processed the keys wrong way resulting
769 * Redefined the mandatory HMAC algorithms and added new algorithms.
770 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
771 and hmac-md5 truncated to 96 bits. The mandatory is now
772 hmac-sha1-96. Rest are optional (including the one that used
773 to be mandatory). Rationale for this is that the truncated HMAC
774 length is sufficient from security point of view and can actually
775 make the attack against the HMAC harder. Also, the truncated
776 HMAC causes less overhead to the packets. See the RFC2104 for
779 * Added new [hmac] configuration section. The SKE used to use
780 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
781 is of course wrong. The official names that must be proposed in
782 the SKE are the ones defined in the protocol specification
783 (hmac-sha1-96 for example). The user can configure any hmac
784 using any hash function configured in the [hash] section. At
785 least, the mandatory must be configured.
787 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
789 * Added HMAC list to the SKE proposal list. It has now both
790 hash algorithm list and HMAC list. This makes the protocol
791 incompatible with previous versions. The SKE now seems to work
792 the way it is supposed to work, for the first time actually.
794 * Defined plain Hash algorithms to the protocol specification.
797 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Implemented support for key agreement packets into the server.
800 Added functions silc_server_key_agreement and
801 silc_server_send_key_agreement. Other than these functions,
802 server has nothing to do with this packet.
804 * Added support for private message key packets into the server.
805 Added functions silc_server_private_message_key and
806 silc_server_send_private_message_key.
810 * Changed the silc_[client|server]_protocol_ke_set_keys to be
811 called in the protocol's final callback instead in the END
812 protocol state. This makes a little more sense and in the same
813 time in client we can use the same protocol routines for normal
814 key exchange and to key agreement packet handling as well.
816 * Added to both client's and server's KE protocol context the
817 SilcSKEKeyMaterial pointer to save the key material. We will
818 bring the key material to the protocol's final callback by doing
819 this. The final callback must free the key material.
821 * Added SKE's packet_send callback into client's KE protocol
822 context so that the caller can choose what packet sending function
823 is used. This way we can use different packet sending when
824 doing normal SKE when doing key agreement packet handling (in
825 the key agreement packet handling we do not want to encrypt
828 * Implemented the responder side of the key agreement routines
829 in the client. The client can now bind to specified port and
830 accept incoming key negotiation. The key material is passed
831 to the application after the protocol is over.
833 * Implemented the processing of incoming Key Agreement packet
834 in the client. Added function silc_client_key_agreement to
837 * Implemented the intiator side of the key agreement routines
838 in the client. The client can now initiate key agreement with
839 another remote client. The key material is passed to the
840 application after the protocol is over.
842 * Created client_keyagr.c to include all the key agreement
845 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
846 SILC_TASK_CALLBACK except that it is not static.
848 * Created client_notify.c and moved the Notify packet handling
849 from the client.[ch] into that file.
851 * Created client_prvmsg.c and moved all private message and
852 private message key routines from the client.[ch] into that file.
854 * Create client_channel.c and moved all channel message and
855 channel private key routines from the client.[ch] into that file.
857 * Changed silc_client_get_client_by_id_resolve to resolve with
858 WHOIS command instead of IDENTIFY command, in the file
859 lib/silclient/idlist.c.
861 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
863 * Implemented the SKE's responder side to the Client library.
865 * When FAILURE is received to the protocol do not trust it
866 blindly. Register a timeout to wait whether the remote closes
867 the connection as it should do it, only after that process the
868 actual failure. This was changed to both client and server.
870 * Added client_internal.h to include some of the structures
871 there instead of client.h in lib/silcclient/.
873 * Added function silc_task_unregister_by_callback to unregister
874 timeouts by the callback function.
876 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Some "Incomplete WHOIS info" errors has been appearing on the
879 log files. Took away the entry->userinfo check from WHOIS
880 reply sending. The entry->userinfo is now " " if client did not
881 provide one. I thought this was fixed earlier but something
882 is wrong still. Let's see if the error still appears.
884 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Fixed a minor bug in the login when the channel key is
887 re-generated in the server. It used to generate the key in
888 wrong order and thus caused problems in the channel traffic.
890 * Fixed a minor bug in channel key distsribution after
891 KICK command. The key was not sent to the router even though
894 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Added silc_ske_process_key_material_data as generic routine
897 to process any key material as the SILC protocol dictates. The
898 function is used by the actual SKE library but can be used by
899 applications as well. This relates to the private message keys
900 and the channel private keys since they must be processed the
901 same way the normal SILC session keys. The protocol dictates
902 this. Affected files: lib/silcske/silcske.[ch].
904 Added also silc_ske_free_key_material to free the
905 SilcSKEKeyMaterial structure.
907 * Defined silc_cipher_set_key function to set the key for
908 cipher without using the object's method function. The affected
909 files: lib/silccrypt/silccipher.[ch].
911 * Implemented silc silc_client_add_private_message_key,
912 silc_client_add_private_message_key_ske,
913 silc_client_del_private_message_key,
914 silc_client_list_private_message_keys and
915 silc_client_free_private_message_keys functions in the
918 Added functions silc_client_send_private_message_key to send
919 the Private Message Key payload and silc_client_private_message_key
920 to handle incoming Private Message Key payload.
922 * Added Cipher field to the Private Message Key payload to set
923 the cipher to be used. If ignored, the default cipher defined
924 in the SILC protocol (aes-256-cbc) is used.
926 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Removed lib/silcclient/ops.h file.
930 Redefined parts of the SILC Client Library API. Created new
931 file silcapi.h that deprecates the ops.h file and defines the
932 published Client Library API. Defined also private message key
933 API and channel private key API into the file.
935 This is the file that the application must include from the
936 SILC Client Library. Other files need not be included by
937 the application anymore.
939 * Added new key_agreement client operation callback and also
940 defined the Key Agreement library API for the application.
942 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
945 is used by clients to request key negotiation between another
946 client in the SILC network. If the negotiation is started it
947 is performed using the SKE protocol. The result of the
948 negotiation, the secret key material, can be used for example
949 as private message key.
951 Implemented the Key Agreement payload into the files
952 lib/silccore/silauth.[ch].
954 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Redefined ciphers for the SILC protocol. Added some new ciphers
957 and defined the key lengths for the algorithms. Changed the
958 code accordingly. The default key length is now 256 bits.
960 * Fixed SKE key distribution function silc_ske_process_key_material
961 when the key length is more than 128 bits. The default key
962 length in SILC is now 256 bits.
964 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
965 to indicate unsupported algorithm.
967 * Renamed rijndael.c to aes.c and all functions as well.
969 * Fixed a long standing channel key setting bug in client library.
970 Weird that it has never surfaced before.
972 * Fixed bug in channel deletion. If the entire channel is removed
973 then it must also delete the references of the channel entry
974 from the client's channel list as the client's channel entry and
975 the channel's client entry share same memory.
977 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Implemented CONNECT and SHUTDOWN commands in the client.
981 * Implemented CLOSE command to the client.
983 * Added the function silc_idlist_find_server_by_name into the
984 files silcd/idlist.[ch].
986 Added the function silc_idlist_find_server_by_conn into the
987 files silcd/idlist.[ch].
989 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * DIE command was renamed to SHUTDOWN. Updated the both code
994 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
995 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
997 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1000 * Added function silc_server_create_connection function to create
1001 connection to remote router. My server implementation actually
1002 does not allow router to connect to normal server (it expects
1003 that normal server always initiates the connection to the router)
1004 so the CONNECT command is only good for connecting to another
1007 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1010 or some other client was kicked from the channel.
1012 Implemented the handling of the notify type to both client
1015 Implemented silc_server_send_notify_kicked to send the KICKED
1016 notify. It is used to send it to the server's primary router.
1018 * Implemented the KICK command into server and client.
1020 * Added `query' argument to the silc_idlist_get_client function
1021 to indicate whether to query the client from server or not if
1024 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1025 to indicate that the client is not channel founder.
1029 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Removed the rng context from SilcPacketContext structure and
1032 changed that the packet routine uses the Global RNG API.
1034 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Added support for quit message that client can "leave" on the
1037 channel when it quits the SILC. It is ditributed inside the
1038 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1040 Added silc_server_free_client_data that will take the
1041 signoff message as argument.
1043 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1045 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Updated parts of the protocol specification to keep it up
1050 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1053 payloads in one packet.
1055 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1056 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1057 use now the new List flag.
1059 * Also deprecated the following packet types: REPLACE_ID,
1060 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1062 * Added list support for Notify packet in server.
1064 * Added silc_server_send_notify_channel_change to send the
1065 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1066 the silc_server_send_replace_id.
1068 * Added silc_server_send_notify_nick_change to send the
1069 NICK_CHANGE notify type. Deprecates the function
1070 silc_server_send_replace_id.
1072 * Added silc_server_send_notify_join to send the JOIN notify type.
1073 Deprecates the function silc_server_send_new_channel_user.
1075 * Added silc_server_send_notify_leave to send LEAVE notify type.
1076 Deprecates the function silc_server_send_remove_channel_user.
1078 * Added silc_server_send_notify_cmode and
1079 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1080 types. Deprecates the silc_server_send_set_mode function.
1082 * Added SERVER_SIGNOFF notify type to indicate that server has
1083 quit. This means that all clients on the channel from that
1084 server will drop. This can be also used when netsplit happens.
1086 Deprecated REMOVE_ID packet type since it is not needed anymore
1089 Added silc_server_send_notify_server_signoff to send the
1090 SERVER_SIGNOFF notify type. Deprecates the function
1091 silc_server_send_remove_id.
1093 Added also silc_server_send_notify_signoff to send the
1094 SIGNOFF notify type.
1096 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1097 SILC protocol from this day on. Changed the protocol
1098 specification as well.
1100 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1101 notify type. It is used between routers to notify about
1102 topic changes on a channel.
1104 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1107 * Partly updated the protocol specification to comply with the
1108 changes now made. It is still though a bit outdated.
1110 * The JOIN notify type now takes one extra argument <Channel ID>.
1111 The packet used to be destined to the channel but now the
1112 JOIN type may be sent as list thus it is impossible to
1113 destine it to any specific channel. By adding this argument
1114 it is again possible.
1116 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added CREDITS file. The CHANGES and CREDITS file will appear
1119 in the distribution as well.
1121 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1124 types in the server's silcd/packet_receive.c.
1126 * Implemented CMODE and CUMODE to work in router environment.
1128 * Fixed minor encoding and decoding buglet from the
1129 lib/silccore/silcmode.c.
1131 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1134 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1136 * Changed all SilcConfigServer* and silc_config_server* to
1137 SilcServerConfig* and silc_server_config*, respectively.
1140 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Associated the ID (client or server ID) to the Authentication
1143 Payload to avoid any possibility of forging. Updated the
1144 protocol specification and the code accordingly.
1146 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * The RSA key length is now save to the RsaKey context in the
1149 key generation process in lib/silccrypt/rsa.c. The key length
1150 is now used to figure out the maximum size of the block allowed
1151 to be encrypted/signed.
1153 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1154 is equivalent to the silc_mp_mp2bin but does not allocate any
1157 * Changed silc_mp_mp2bin API to take length argument. If it is
1158 non-zero then the buffer is allocated that large. If zero, then
1159 the size is approximated using silc_mp_sizeinbase, which however
1162 * Created Global RNG API which is global RNG that application can
1163 initialize. After initializing, any routine anywhere in the
1164 code (including library) can use RNG without allocating a new
1165 RNG object. This was done to allow this sort of use of the
1166 RNG in code that has no chance to allocate RNG object. All
1167 applications currently allocate this and many routines in the
1168 library use this. Affected file lib/silccrypt/silcrng.[ch].
1170 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1171 it to use the Global RNG API.
1173 * Defined Authentication Payload into protocol specification that
1174 is used during SILC session to authenticate entities. It is
1175 used for example by client to authenticate itself to the server
1176 to obtain server operator privileges.
1178 Implemented this payload into the lib/silccore/silcauth.[ch].
1179 Implemented also routines for public key based authentication
1180 as the new protocol specification dictates.
1182 Moved definitions of different authentication methods from
1183 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1185 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1186 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1187 silc_pkcs_verify_with_hash functions into the file
1188 lib/silccrypt/silcpkcs.[ch].
1190 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * The client entry's userinfo pointer must be always valid.
1193 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1194 will fail since it requires the userinfo. Now, the userinfo
1195 is allocated as "" if actual userinfo does not exist. Actually,
1196 it must exist and it is totally Ok to drop client connections
1197 that does not announce the userinfo. However, we will make
1198 this workaround for now.
1200 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1201 to return the remote port by socket.
1203 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1206 SILC_SERVER_PENDING_EXEC and added an new macro
1207 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1208 data or when error occurs while processing the pending command.
1210 Added new argument `destructor' into silc_server_command_pending
1211 and to the SilcServerCommandPending object. This destructor is
1212 now called after calling the pending callback or if error occurs
1213 immediately. If error occurs the actual pending callback won't
1214 be called at all - only the destructor. The destructor may be
1215 NULL if destructor is not needed.
1217 All this applies for client library code as well. Similar
1218 changes were made there as well for the pending commands.
1220 In the client, the application must now allocate the
1221 SilcClientCommandContext with the silc_client_command_alloc
1224 * Added reference counter to the SilcServerCommandContext. Added
1225 function silc_server_command_alloc and silc_server_command_dup
1228 Same type of functions added to the client library for the same
1231 * Removed the cmd_ident from IDListData away since it is now
1232 global for all connections. It is the command identifier used
1233 in command sending and with pending commands. The affected file
1236 * Added reference counter to the SilcSocketConnection objecet to
1237 indicate the usage count of the object. The object won't be
1238 freed untill the reference counter hits zero. Currently only
1239 server uses this, and client ignores it. The client must be
1240 set to use this too later. The affected files are
1241 lib/silccore/silcsockconn.[ch]. Added also the function
1242 silc_socket_dup to increase the reference counter.
1244 This was mainly added because it is possible that the socket
1245 is removed underneath of pending command or other async
1246 operation. Now it won't be free'd and proper DISCONNECTING
1247 flags, etc. can be set to avoid sending data to connection that
1248 is not valid anymore.
1250 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1251 the connection. After that it sets SILC_SET_DISCONNECTED.
1252 It is, however, possible that the socket data is not still freed.
1253 The silc_server_packet_process now checks that data is not
1254 read or written to connection that is DISCONNECTED. The socket
1255 get's freed when the reference counter hits zero.
1257 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Changed the client operation API: channel_message operation's
1260 `sender' is now the client entry of the sender, not the nickname
1261 and the `channel' is the channel entry, not the channel name.
1263 In the private_message operation the `sender' is now also the
1264 client entry of the sender not the nickname.
1266 Affected file is lib/silcclient/ops.h and all applications
1267 using the client operations.
1269 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Moved the calling of ops->connect() from connect_to_server_final
1272 into receive_new_id functin since that is the point when the
1273 client is actually allowed to send traffic to network. The
1274 affected file is lib/silcclient/client.c.
1276 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1279 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1280 (if needs broadcasting) instead of broadcasting the packets one
1281 by one which would make a burst in the network traffic.
1283 * Added `broadcast' argument to the functions in silcd/server.[ch]
1284 silc_server_create_new_channel[_with_id] to indicate whether
1285 to send New Channel packet to primary router.
1287 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added new function into the silcd/server.[ch] files:
1290 silc_server_create_new_channel_with_id to create new channel with
1291 already existing Channel ID.
1293 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1294 lib/silccore/silcpacket.h. This packet is used t send list of
1295 Set Mode payloads inside one packet. Server uses this to set
1296 the modes for the channels and clients on those channels, that it
1297 announced to the router when it connected to it. The protocol
1298 specification has been updated accordingly.
1300 * The silc_server_new_channel did not handle the packet coming
1301 from normal server as it normally does not send that. However,
1302 when it announces its channels it does send it. Implemented
1303 the support for that.
1305 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1306 into the file lib/silccore/id.h.
1308 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Fixed memory leaks in the functions silc_idlist_del_client,
1311 silc_idlist_del_channel and silc_idlist_del_server in the file
1312 silcd/idlist.c. All of those leaked like a sieve.
1314 * Fixed some small memory leaks in the client's function
1315 silc_client_notify_by_server.
1317 * Added functions into silcd/server.c: silc_server_announce_clients,
1318 silc_server_announce_channels and silc_server_announce_server.
1319 These functions are used by normal and router server to announce
1320 to its primary router about clients, channels and servers (when
1321 router) that we own. This is done after we've connected to the
1324 These functions effectively implements the following packet types:
1325 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1326 and SILC_PACKET_NEW_ID_LIST.
1328 * Added new functions into the silcd/packet_receive.[ch]:
1329 silc_server_new_id_list, silc_server_new_channel_list and
1330 silc_server_new_channel_user_list to handle the incoming
1331 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1333 * Added support of changing Channel ID in the function
1334 silc_server_replace_id. If the server that announces a channel
1335 to the router already exists in the router (with same name but
1336 with different Channel ID), router is responsible to send
1337 Replace ID packet to the server and force the server to change
1338 the Channel ID to the one router has.
1340 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1341 client that the Channel ID has been changed by the router. The
1342 normal server sends this to the client. Client must start using
1343 the new Channel ID as the channel's ID.
1345 Implemented handling of this new type into lib/silcclient/client.c
1346 into the function silc_client_notify_by_server.
1348 * Added new function silc_idlist_replace_channel_id into the files
1349 silcd/idlist.[ch] to replace the Channel ID.
1351 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Call silc_server_command_identify_check always when processing
1354 the IDENTIFY command in silcd/command.c
1356 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1359 send keepalive packets. The packet can be sent by clients,
1360 servers and routers.
1362 Added function silc_socket_set_heartbeat into the file
1363 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1364 If not set, the heartbeat is not performed. The actual
1365 heartbeat is implemented in the low level socket connection
1366 library. However, application is responsible of actually
1369 Added silc_server_send_heartbeat to send the actual heartbeat
1370 packet into silcd/packet_send.[ch]. Server now performs
1371 keepalive with all connections.
1373 * Added silc_task_get_first function into lib/silcutil/silctask.c
1374 to return the timeout task with shortest timeout. There was a bug
1375 in task unregistration that caused problems. TODO has been
1376 updated to include that task system must be rewritten.
1378 * The client library will now resolve the client information when
1379 receiving JOIN notify from server for client that we know but
1380 have incomplete information.
1382 * Rewrote parts of silc_server_remove_from_channels and
1383 silc_server_remove_from_one_channel as they did not remove the
1384 channel in some circumstances even though they should've.
1386 * Encryption problem encountered in server:
1388 The LEAVE command used to send the Channel Key packet to the
1389 router immediately after generating it. However, the code
1390 had earlier sent Remove Channel user packet but not immediately,
1391 ie. it was put to queue. The order of packets in the router
1392 was that Channel Key packet was first and Remove Channel User
1393 packet was second, even though they were encrypted in the
1394 reverse order. For this reason, MAC check failed. Now, this
1395 is fixed by not sending the Channel Key packet immediately but
1396 putting it to queue. However, this is more fundamental problem:
1397 packets that are in queue should actually not be encrypted
1398 because packets that are sent immediately gets encrypted
1399 actually with wrong IV (and thus MAC check fails). So, packets
1400 that are in queue should be encrypted when they are sent to
1401 the wire and not when they put to the queue.
1403 However, the problem is that the current system has not been
1404 designed to work that way. Instead, the packet is encrypted
1405 as soon as possible and left to the queue. The queue is then
1406 just purged into wire. There won't be any fixes for this
1407 any time soon. So, the current semantic for packet sending
1410 o If you send packet to remote host and do not force the send
1411 (the packet will be in queue) then all subsequent packets to the
1412 same remote host must also be put to the queue. Only after the
1413 queue has been purged is it safe again to force the packet
1416 o If you send all packets immediately then it safe to send
1417 any of subsequent packets through the queue, however, after
1418 the first packet is put to queue then any subsequent packets
1419 must also be put to the queue.
1421 Follow these rules and everything works fine.
1423 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added new function silc_server_remove_clients_by_server to
1426 remove all client entries from ID list when the server connection
1427 is lost. In this case it is also important to invalidate all
1428 client entires as they hold the invalid server entry. This
1429 fixes fatal bug when server has lost connection and will reconnect
1432 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Made some sanity checks to silc_server_daemonise like to check
1435 whether the requested user and group actually exists.
1437 * Added sanity check to SKE's silc_ske_responder_finish to check
1438 that the public and private key actually is valid.
1440 * Invalidate the client's nickname when receiving Replace ID
1441 packet and the Client ID is being replaced. This means that the
1442 server will query the nickname if someone needs it (client)
1445 * Sort the ID Cache in client library when the ID Cache data
1446 has changed (needs sorting).
1448 * Do not allow for SILC client to create several connections to
1449 several servers. The client does not support windows right now
1450 and generating multiple connections causes weird behaviour.
1452 Irssi-silc client does support windows and can handle several
1453 connections without problems, see: www.irssi.org and SILC plugin.
1455 * Fixed some places where client was added to the IDList. The
1456 rule of thumb is following (in order to get everything right):
1457 If the client is directly connected local client then the
1458 `connection' argument must be set and `router' argument must be
1459 NULL to silc_idlist_add_client function. If the client is not
1460 directly connected client then the `router' argument must
1461 bet set and the `connection' argument must be NULL to the
1462 silc_idlist_add_client function.
1464 * The funtion silc_server_packet_send_local_channel actually did
1465 not check whether the client was locally connected or not. It
1466 does that now. Fixed a bug related to LEAVE command.
1468 * Fixed Remove Channel User payload parsing bug in server's
1469 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1471 * The server's silc_server_save_channel_key now checks also the
1472 global ID list for the channel as it might not be in the local
1473 list. Fixed a bug related to LEAVE command.
1475 * Is this the end of the [<unknown>] buglet that has been lurking
1476 around for a long time? A little for loop fix in server's
1477 silc_server_command_whois_parse that is used by both IDENTIFY
1478 and WHOIS command. At least, this was a clear bug and a cause
1479 of one type of [<unknown>] buglet.
1481 * WHOIS and IDENTIFY commands call the function
1482 silc_server_command_[whois/identify]_check function even if
1483 we are not router server.
1485 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Added --with-gmp configuration option. If set the GMP
1488 is always compiled in the SILC source tree. If not set then
1489 it is checked whether the system has the GMP3 installed. If
1490 it has then the GMP won't be compiled (the system's headers
1491 and library is used), if it doesn't have it then the GMP is
1492 compiled in the SILC source tree.
1494 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Changed RSA private exponent generation to what PKCS #1
1497 suggests. We try to find the smallest possible d by doing
1498 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1499 not security fix but optimization.
1501 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Added new config entry [Identity] to fork the server and run
1504 it as specific user and group. A patch from Bostik.
1506 * Imported Dotconf configuration library into lib/dotconf.
1507 This will be used to create the SILC configuration files later.
1508 It will appear in the distsribution after this commit.
1510 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * A big code auditing weekend happening. Auditing code for
1513 obvious mistakes, bugs and errors. Also, removing any code
1516 Removed files for being obsolete:
1518 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1519 inline in the file lib/silcutil/silcbuffer.h)
1521 o lib/silcutil/silcbufutil.c (the header has inline versions)
1523 Changed code to fix possible error conditions:
1525 o The buffer formatting routines now check that the destination
1526 buffer really has enough space to add the data. This applies for
1527 both buffer formatting and unformatting
1528 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1529 unformatting was changed to accomodate following rules:
1530 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1531 sent to the function while XXX_*STRING will not allocate or copy
1532 the data into the buffer. Instead it sets the pointer from the
1533 buffer into the pointer sent as argument (XXX_*STRING used to
1534 require that the pointer must be allocated already). This change
1535 makes this whole thing a bit more consistent and more optimized
1536 (note that the data returned in the unformatting with XXX_*STRING
1537 must not be freed now). The routines return now -1 on error.
1539 o Tried to find all code that use buffer_format and buffer_unformat
1540 and added return value checking to prevent formatting and
1541 especially unformatting errors and possible subsequent fatal
1544 o Changed ske->x and ske->KEY to mallocated pointers in
1545 lib/silcske/silcske.h. Fixed possible data and memory leak.
1547 o Added return value checking to all *_parse* functions. Fixed
1548 many memory leaks as well.
1550 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1551 so that buffer overflows would not happen. All code now also
1552 checks the return value as it can fail.
1554 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Added reconnection support to server if the normal server looses
1557 its connection to the router (for example if router is rebooted).
1558 The server performs normal reconnection strategy implemented
1559 to the server. Affected file silcd/server.c.
1561 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Added new packet type SILC_PACKET_SET_MODE that is used to
1564 distribute the information about changed modes (for clients,
1565 channels and clients channel modes) to all routers in the
1566 network. Updated the protocol specification accordingly.
1568 Added functions into silcd/packet_send.c and
1569 silcd/packet_receive.c: silc_server_send_set_mode,
1570 silc_server_set_mode.
1572 Added new files silcmode.[ch] into lib/silccore that implements
1573 the encoding and decoding of Set Mode Payload. Added new type
1574 SilcSetModePayload. Moved the definitions of different modes
1575 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1577 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Oops, a little mistake in server's connection authentication
1580 protocol. The protocol is not ended with FAILURE but with
1581 SUCCESS if the authentication is Ok. :) Affected file is
1584 * Implemented NICK_CHANGE notify handling in server in the file
1585 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1586 the local clients on the channel. After the changing nickname
1587 in router environment snhould work and the [<unknown>] nickname
1588 should appear no more.
1590 The silc_server_replace_id function that receives the Replace ID
1591 payload now sends the NICK_CHANGE notify type also in the file
1592 silcd/packet_receive.c
1594 * Changed WHOIS and IDENTIFY command to support the maximum amount
1595 of arguments defined in protocol specs (3328 arguments). This
1596 fixed a bug that caused problems when there were more than three
1599 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Added extra parameter, command identifier, to the
1602 silc_client_send_command so that explicit command identifier
1605 Changed that ID list routines uses specific command identifier
1606 when sending WHOIS/IDENTIFY requests to the server so that they
1607 can be identified when the reply comes back.
1609 Affected files lib/silcclient/command.[ch],
1610 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1612 * Added `sender' argument to silc_server_packet_send_to_channel
1613 to indicaet the sender who originally sent the packet to us
1614 that we are now re-sending. Ignored if NULL. Affected file
1615 silcd/packet_send.[ch].
1617 * Added some server statistics support in silcd/server_internal.h
1618 SilcServerStatistics structure and around the server code. Also
1619 send some nice statistics information when client is connecting
1622 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Fixed channel ID decoding in server's JOIN command reply in
1625 silcd/command_reply.c
1627 * Fixed braodcasting of replace ID payload to not to send it if
1628 we are standalone server in silcd/packet_receive.c.
1630 * Fixed all channel message sending routines to not to send
1631 packets to clients that has router set, since they are routed
1632 separately in the same function earlier. Affects file
1633 silcd/packet_send.c and all channel packet sending functions.
1635 * In USERS reply, res_argv[i] are not allocated, the table
1636 is allocated. Thus changed that free the table, not its
1639 * In server's whois_check and identify_check if the client is
1640 locally connected do not send any WHOIS commands - they are not
1643 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Fixed some minor bugs in client when sending WHOIS command. The
1646 arguments was in wrong order.
1648 * Removed statis function add_to_channel from server in
1649 silcd/command.c that was previously used with the joining but
1652 * Tested USERS command in router environment successfully with two
1653 routers, two servers and two clients.
1655 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Reorganized the USERS command and command reply in client library
1658 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1659 When the command is given by user we register a pending command
1660 callback that will reprocess the command after the reply has been
1661 received from the server. When reprocessing the packet we then
1662 display the information. Thus, the USERS information is displayed
1663 now in the command callback instead of in the command reply
1664 callback. The processing of the command is same as previously
1665 when server has sent the command reply in the JOINing process.
1667 * Added to USERS command in silcd/command_reply.c to join the client,
1668 we didn't use to know about, to the channel after we've created
1669 a client entry for it. Also, for clienet we did know already still
1670 check whether it is on the channel or not and add it if not.
1672 * Removed silc_server_command_join_notify as the function and its
1675 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Changed the client's pending command handling to the same as the
1678 server's pending command handling. It is also now possible to
1679 execute command reply functions from other command reply
1680 function as the function callbacks for commands and command
1681 replies are one and same. The pending commands are not static
1682 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1683 in client connection context. Thus, pending commands are server
1684 connection specific as it is convenient.
1686 Changed the function silc_client_command_pending and
1687 silc_client_command_pending_del and added new function
1688 silc_client_command_pending_check. Removed the
1689 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1692 * Added cmd_ident, current command identifier, to the client
1693 connection context in lib/silcclient/client.h to keep track on
1694 command identifiers used in command sending. Client's command reply
1695 function handling now supports the mandatory command identifiers.
1697 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1698 funtions in client to fully support pending command callbacks.
1700 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1701 as one of the arguments to the application in the command reply
1704 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1705 before first releasing SILC but came back. Now it is removed again
1706 and should come back nomore. The FORWARDED flag was used only
1707 by the JOINing procedure by forwarding the command packet to router.
1708 Now, the JOINing procedure has been changed to more generic (due
1709 to various router environment issues) and FORWARDED is not needed
1710 anymore for anything. The protocol specification is yet to be
1713 Now, removed silc_server_packet_forward from server and the flag
1714 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1716 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Renamed NAMES command to USERS command. The NAMES was named that
1719 due to historical reasons. Now it is renamed. Also, rewrote
1720 parts of the USERS command. The nickname list is not sent anymore
1721 by the server. Only Client ID and mode lists are sent in the USERS
1722 command. Changed this also to the protocol specification.
1724 The client now resolves the names and stuff after it receives
1725 the USERS list from the server when joining to the channel.
1727 * WHOIS and IDENTIFY commands has been changed to support multiple
1728 Client ID's per command. One can now search for multiple users
1729 in the network by sending only one WHOIS or IDENTIFY command.
1730 Changed the code and the protocol specifications.
1732 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1733 uses silc_server_command_whois_parse to parse the request. */
1735 * If normal server, do not parse the WHOIS and IDENTIFY requests
1736 before sending it to the router. Saves some time.
1738 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Fixed JOIN command on client library. Wrong number of arguments
1741 used to crash the client.
1743 * Added silc_server_channel_has_global function to check whether
1744 channel has global users or not.
1746 * Added silc_server_channel_has_local function to check whether channel
1747 has locally connected clients on the channel.
1749 * The silc_server_remove_from_one_channel now checks whether the
1750 channel has global users or not after given client was removed from
1751 the channel. It also checks whether the channel has local clients
1752 on the channel anymore. If it does not have then the channel entry
1753 is removed as it is not needed anymore.
1755 * The silc_server_notify now checks on JOIN notify whether the joining
1756 client is one of locally connected or global. If it is global then
1757 the channel has now global users on the channel and that is marked
1758 to the channel entry. Also, it now saves the global client to
1759 global list who is joining and JOINs it to the channel. This is
1760 for normal server, that is.
1762 Changed silc_server_send_notify_on_channel,
1763 silc_server_packet_relay_to_channel and
1764 silc_server_packet_send_to_channel check if we are normal server
1765 and client has router set (ie. global client) do not send the
1766 message to that client, as it is already routed to our router.
1768 * Implemented LEAVE notify type handling in silc_server_notify
1771 * Tested LEAVE command in router environment successfully. Tested
1772 with two routers, two servers and two clients.
1776 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1778 * Implemented SIGNOFF notify type handling in silc_server_notify
1781 * silc_server_remove_id now removes the client entry from all channels
1782 it has joined and thusly sends SIGNOFF notify type.
1784 * Rewrote the NAMES list generation in server by removing two excess
1785 loops. The lists are created now inside one loop.
1787 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * silc_server_remove_channel_user checks now also global list
1790 for channel and client.
1792 * silc_server_new_channel_user checks now both local and global
1793 list for channel and client. Fixed a bug in client id decoding.
1794 Used to decode wrong buffer.
1796 * silc_server_channel_message checks now both local and global
1797 list for channel entry.
1799 * Tested channel joining (hence JOIN) in router environment
1800 successfully. Tested with two routers, two servers and two
1803 * Tested channel message sending in router environment successfully.
1805 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Added silc_server_save_channel_key into server.[ch] to save the
1808 received channel key in Channel Key payload processing. It is
1809 also used in JOIN command reply handling.
1811 Equivalent function silc_client_save_channel_key added into
1812 client.[ch] into client library.
1814 * Changed JOIN command reply to send information whether the channel
1815 was created or not (is existing already) and the channel key
1816 payload. Changed protocol specs accordingly.
1818 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1819 the request was sent by ID and not by nickname. Crashed on
1822 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1825 now correctly save the received data.
1827 * silc_server_free_sock_user_data now notifies routers in the
1828 network about entities leaving the network.
1830 At the same time implemented functions silc_server_remove_id
1831 and silc_server_send_remove_id to receive and send REMOVE_ID
1832 packets. The packet is used to notify routers in the network
1833 about leaving entities. The ID removed will become invalid in
1836 * Added function silc_idlist_del_server into server. Removes and
1837 free's server entry from ID list.
1839 * silc_server_private_message function now checks, if we are router,
1840 that the destination ID really is valid ID, naturally.
1842 * In router when NEW_ID packet is received (for new client) the
1843 hash of the Client ID is saved in the ID Cache but the
1844 client->nickname is set to NULL, instead of putting the hash
1847 IDENTIFY command now also checks that client->nickname must be
1848 valid. If it is not if will request the data from the server who
1849 owns the client. Added new function
1850 silc_server_command_identify_check.
1852 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1853 to set the command to already allocated Command Payload.
1855 * Tested private message sending in router environment with two
1856 routers, two servers and two clients. Fixed minor bugs and now
1859 * Fixed segfault from client's NAMES command. Used to crash if
1862 * Forwarded packets must not be routed even if it is not destined
1863 to the receiver. Changed server code comply with this.
1865 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Added `require_reverse_mapping' boolean value to ServerParams
1868 structure. If TRUE (not default) the server will require that
1869 the connecting host has fully qualified domain name.
1871 If the reverse mapping is not required and hostname could not be
1872 found the IP address is used as hostname.
1874 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Implemented version string checking to both client and server.
1877 The check is incomplete currently due to the abnormal version
1878 strings used in development version of SILC.
1880 * Changed all command functions in server to use the new
1883 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Changed char *data to unsigned char *data in ID Cache system to
1886 support binary data as ID Cache data. Changed code to support
1887 binary data in lib/silccore/idcache.c.
1889 * Renamed silc_server_packet_relay_command_reply to
1890 silc_server_command_reply as it is normal packet receiving
1891 function. Rewrote the function to accept command replys for
1892 servers and not only for clients.
1894 * Mark remote router always as registered server if we are connecting
1895 to it. Otherwise, commands sent by the router to us are ignored.
1897 * All ID List find routines now returns the ID Cache Entry pointer
1898 as well if requested.
1900 * WHOIS command works now in router environment, tested with two
1901 routers, two servers and two clients.
1903 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1904 in router environment (as it is almost equivalent to WHOIS) but
1905 hasn't been tested thoroughly. Added new functions:
1907 silc_server_command_identify_parse
1908 silc_server_command_identify_send_reply
1909 silc_server_command_identify_from_client
1910 silc_server_command_identify_from_server
1912 * Disabled route cache adding because adding two different ID's with
1913 same IP replaces the old cache entry thus giving wrong route.
1914 The entry->router->connection is always the fastest route anyway
1915 so route cache may not be needed. Of course, new routes maybe
1916 established after receiving the ID when the entry->router->connection
1917 might not be anymore the most optimal.
1919 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Add route cache for received ID for fast routing.
1923 * Added silc_server_packet_route to route received packet on router
1924 that is not destined to us.
1926 * Renamed silc_server_get_route to silc_server_route_get.
1928 * Added id_string and id_string_len fields into SilcServer to
1929 include encoded ServerID for fast comparing without excess
1930 encoding of the ID's.
1932 * Cleaned up WHOIS command on server side. Added following static
1935 silc_server_command_whois_parse
1936 silc_server_command_whois_check
1937 silc_server_command_whois_send_reply
1938 silc_server_command_whois_from_client
1939 silc_server_command_whois_from_server
1941 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1942 arguments in command replies. All command functions should be
1943 updated to use this macro.
1945 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Minor typo fixes on command reply handling on server.
1949 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Added silc_server_command_add_to_channel internal routine to add
1952 the client to the channel after router has created the channel and
1953 sent command reply to the server.
1955 * Added generic silc_server_send_command to send any command from
1958 * Use static buffer with ID rendering instead of duplicating data.
1960 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Fixed a channel user mode bug when joining to a channel server gave
1963 everybody channel founder rights, oops.
1965 * We mark ourselves as the router of the incoming server connection
1966 if we are router ourselves. This way we can check in some packet
1967 sending functions whether it is locally connected server. For
1968 incoming router connections we put NULL.
1970 * For router sending packets locally means now always sending the
1971 packet cell wide; to local clients and local servers. For normal
1972 server sending packet locally means sending it to only local
1975 * Fixed the JOIN command to really work in router environment. If the
1976 channel is created it is always created by the router. Router is
1977 also responsible of making the initial joining to the channel,
1978 sending JOIN notify to the sending server and distributing
1979 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1980 does not exist server doesn't do anything else but forward the
1981 command to the router which performs everything.
1983 * Added silc_server_send_channel_key function to send the Channel Key
1986 * Added silc_server_create_channel_key to create new channel key. The
1987 channel key is now re-generated everytime someone joins or leaves
1988 a channel, as protocol dictates. Note: channel->key_len is the
1991 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1994 packet_receive.[ch] to separate packet sending and receiving
1995 routines. The server.[ch] now includes everything else including
1996 actual packet processing (writing and reading data) and other
1999 Renamed silc_server_private_message_send_internal to
2000 silc_server_send_private_message. The routine is still though
2001 used only to relay private messages as server does not send
2002 private messages itself.
2004 Renamed silc_server_new_channel to silc_server_create_new_channel
2005 and added new function sicl_server_new_channel that handles the
2006 incoming New Channel packet. Added also new sending function
2007 silc_server_send_new_channel to send New Channel Payload.
2009 * Added new function silc_server_notify to process incoming notify
2010 packet to the server/router. Server may then relay the notify
2011 to clients if needed.
2013 * Added new function silc_server_new_channel_user to process incoming
2014 New Channel User packet. Router will redistribute the packet and
2015 send JOIN notify to its local clients and locally connected servers
2016 if needed. Normal server will send JOIN notify to its local client
2017 on same channel when received this packet. Added also corresponding
2018 sending function silc_server_send_new_channel_user to sent the
2021 * Added boolean route argument to send_notif_to_channel and
2022 packet_send_to_channel functions to attempt to route the packet
2023 if it is TRUE and send only locally if it is FALSE.
2025 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * silc_server_replace_id now broadcasts the received replace ID
2028 packet if it is not broadcast packet already. The router must
2029 broadcast to inform other routers about changed ID.
2031 * Added backpointer to server's router into SilcServer context in
2032 silcd/server_internal.h.
2034 * Fixed silc_server_packet_broadcast to send correct broadcast
2037 * The channel key is now distributed to the local client as soon
2038 as it is received from the router (in router environment) so that
2039 no other packet may be sent for the channel until client has
2042 * silc_server_remove_channel_user now broadcasts the received
2043 Remove Channel User packet if it is not broadcast packet already.
2044 The router must broadcast to inform other routers about removed
2047 * Added users field into SilcPacketContext that is a reference count
2048 of the context. One can increase the reference count by calling
2049 silc_packet_context_dup which is now changed to just increase the
2050 reference count instead of duplicating the data. The reference
2051 count is decresed by calling silc_packet_context_free that will
2052 free the data after the reference count hits zero.
2054 For now on the packet context and everything allocated into it
2055 (including the raw packet from network) must be freed by calling
2056 the new silc_packet_context_free function. Added also new function
2057 silc_packet_context_alloc that must be used now to allocate the
2058 context. This also means that if a routine is asynchronous from
2059 silc_[client/server]_packet_parse_type the packet context must
2060 be duplicated by calling silc_packet_context_dup. Otherwise it
2061 gets free'd after silc_[client/server]_packet_parse_type returns.
2062 Also, one must remember that if packet is duplicated then its
2063 reference count must be decresed by calling the free function as
2064 many times as it was duplicated.
2066 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2067 from both client and server.
2069 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Made joining to a channel working in router environment.
2073 * Cleaned up JOIN command on server side and create function
2074 silc_server_command_join_channel internal routine to make the
2077 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Changed silc_command_pending list to SilcDList. Also, added
2080 `ident' field to SilcServerCommandPending structure to identify
2081 the reply and to call correct callback.
2083 Added silc_server_command_pending_check function to replace the
2084 corresnponding macro. The silc_command_pending list is not
2087 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2088 to set identifier to previously allocated Command Payload. It
2089 is used to set identifier for command when resending Command
2092 * Added silc_command_payload_encode_payload to encode Command
2093 Payload buffer from SilcCommandPayload structure.
2095 * Added silc_argument_payload_encode_payload to encode Argument
2096 payload buffer from SilcArgumentPayload structure.
2098 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Changed WHOIS command to support router connection on server side.
2101 The whois request is always sent to router unless the server is
2102 standalone server. After server has received the reply from the
2103 router will it send the reply to the client.
2105 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2106 broadcast received broadcast packet. The function is used only
2107 by router. The broadcast packet is always sent to the router's
2110 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2111 render given ID to printable string, for log files for example.
2113 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Made basic router to router connections working. At least they
2116 can now connect to each other but nothing really works the way
2117 they are supposed - yet.
2119 * Added new initiator token to RouterConnection configuration
2120 file in silcd/serverconfig.[ch]. It is used to tell whether we
2121 are the initiator to the remote router or whether we'll expect
2122 the other end to connect.
2124 * Moved registering of listener task to silc_server_init, hence
2125 the server starts listenning as soon as it is run, even if it
2126 does not have connections to other routers. Let's see how well
2129 * Changed default connection retry timeouts for more suitable in
2132 * Removed cipher and such arguments from silc_idlist_add_client
2133 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2134 Added new function silc_idlist_add_data to add the keys and stuff
2137 * Added SilcIDListData structure and added it to SilcClientEntry
2138 and SilcServerEntry as their first field in the structure. This
2139 way we can explicitly cast the ID entries to the SilcIDListData
2140 structure and get common data for the entries. In past, we had
2141 to first check what type of connection it is and then cast it to
2142 correct ID entry type. Now, we can directly cast the opaque
2143 pointer to the SilcIDListData (no matter what ID entry it actually
2144 is) and get the data needed.
2146 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2149 in some circumstances even if threre were timeout tasks, though not
2150 IO tasks, but tasks anyway. Now fixed.
2152 * Defined SilcServerConnection structure to hold connection specific
2153 stuff about directly connected servers and routers. The definition
2154 is currently in silcd/server_internal.h. I thought about having
2155 a bit more important role fro this struct but for now it is used
2156 only when connecting to other server (or router actually).
2158 * Added connecting retry support in server when connecting to
2159 router(s). The retry feature implement exponential backoff
2160 algorithm. Also, added SilcServerParams structure to hold default
2161 parameters for server. For now, it include these retry settings
2162 and are hard coded. After server is moded to be as Silc Server
2163 Library this structure will be more important.
2165 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Changed client librarys channel->clients table to SilcList and
2168 changed code accordingly.
2170 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Changed client's channel table to SilcList and changed code
2173 accordingly. Also changed SilcChannelClientEntry to include back-
2174 pointer to the channel so that client entry can use that structure
2175 as list as well and we have fast cross-reference to the channel.
2176 This change dramatically decreased the complexity of channel
2177 handling with client entry and vice versa (removed one extra
2178 loop when searching for channel entry from many functions).
2180 * Changed server->sim from table to SilcDList and changed code
2183 * NAMES command can now be used from user interface. It will show
2184 the user list on the channel, neatly.
2186 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2187 Code now saves realname of the user if it becomes available.
2189 * Renamed configure.in to configure.in.pre and made ./prepare
2190 script to automatically add correct version string to
2191 configure.in which it creates from configure.in.pre.
2193 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * NAMES command reply now shows users mode with the nickname when
2198 * Moved silc_client_ch[u]mode[_char] functions from
2199 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2200 place sucks, they are utility functions and should be in some
2203 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2205 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2208 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2212 * Added TRQ (efficient deque and list library) into lib/trq. This is
2213 a very good list library that is currently used in the SILC. Defined
2214 SilcList API over the library because I didn't like the API very
2215 much. See lib/trq/silclist.h for the API and examples of how to
2216 use the API. Fixed various places in the code to use the new
2217 SilcList API. The SilcList is meant for lists that has a structure
2218 already defined as a list. It is not suitable to add just some
2219 context to the list (in TRQ, the context is the list actually).
2221 So, I defined SilcDList that can be used for the purpose where
2222 predefined list structure does not exit. This can be used as
2223 such list. Now some context just can be added to the SilcDList.
2224 Currently this list is not used in the SILC just yet, though there
2225 are a lot places where this can replace dynamically allocated
2226 tables and I will fix these places, later, to use SilcDList.
2227 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2228 and use TRQ internally).
2230 Also fixed some annoying warning messages that the original TRQ
2231 code generated. Also minor changes to TRQ's Makefile.in.
2233 * Added support for querying by Client ID to both WHOIS and
2234 IDENTIFY commands into server, as required by the protocol.
2236 * Removed method function pointers from SilcBuffer structure. They
2237 weren't used to anything and just increased the context size for
2238 no good reason. This change also made silc_buffer_alloc and
2239 silc_buffer_free functions inline functions.
2241 * Disabled command flooding detection support until it's fixed so
2242 that it accepts commands in but does not execute them more than once
2245 * Added silc_net_localhost(), to return local hostname, into
2246 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2247 that must be initialized before calling silc_client_init.
2249 * Added new function: silc_server_send_notify_on_channels to send
2250 notify messages to all channels client has joined. It is assured
2251 that the message is sent only once per client.
2253 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2254 lib/silcutil/silcutil.[ch] as silc_format function. The new
2255 function is generic and is used by server as well, not only by
2256 the logging routines.
2258 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2259 the provided version string was not acceptable. Added new function:
2260 silc_ske_check_version into lib/silcske/silcske.h. The function
2261 must be implemented by the application (client or server) and it
2262 does not reside in the SKE library. The function checks the version
2263 string remote end sent.
2265 * Added back pointers (to opaque context and to SilcSocketConnection)
2266 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2268 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2269 duplicate packet context structure.
2271 * Changed `notify' client operation to send same arguments as client
2272 receives from server except for ID's. ID's are mapped to correct
2273 ID entry and that is returned. Also, if channel entry is not sent
2274 by server but the notify is for channel the channel entry is sent
2275 to application (otherwise application doesn't know that it is for
2276 channel (library gets it from packet's Destination ID)).
2278 * Added silc_client_remove_from_channels into client library to
2279 remove a client from all channels it has joined to. Used when
2280 received SIGNOFF notify from server. Added also new function
2281 silc_client_replace_from_channels to replace old ID entry with
2282 new ID entry on all channels. Used when received NICK_CHANGE
2285 * Fixed ID Cache list handling in silc_idlist_get_client in
2286 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2287 to get (or query) client by ID.
2289 * Updated TODO list.
2291 * Added connection authentication status message defined by the
2292 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2293 support for these into the code in client and server side.
2295 * Added generic function silc_client_send_command to send any command
2296 with variable argument list. Application should use this function
2297 to send commands if the command functions provided by the library
2298 does not suite for the application's user interface needs.
2300 * Added new `failure' client operation. Application is notified about
2301 received failure packet if client is executing a protocol. In this
2302 case the protocol's execution has failed.
2304 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2305 is required by the protocol.
2307 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2308 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2311 * Added status flag to SilcSKE object to indicate realtime status
2312 of the SKE protocol.
2314 * Application receives now exactly same command reply arguments as
2315 the library receives from server. However, if ID is received the
2316 corresponding ID entry is returned to the application (eg. Client
2317 ID is mapped to correct SilcClientEntry entry and that is returned).
2318 Changed command_reply client operation due to this change.
2320 * Changed all ID's in commands and in command replys as ID Payloads.
2321 Change affected both client and server side codes.
2323 All ID's sent in SILC network (with execption of ID's in SILC
2324 Packet header) are sent in ID Payload to support variable length
2327 * Server now notifies nick changes and notifies all clients on
2328 the channels about the new nickname (about the new Client ID,
2331 * Implemented CMODE command to change channel modes. Supports all
2332 channel modes defined by the protocol specs except ban and invite
2333 lists. (Also, private channel key mode is supported but support for
2334 setting private channel key in client is missing, thus, this mode
2335 has no effect on client side (except that server requires that the
2336 client uses private channel key and normal channel traffic does not
2339 Also, invite mode works per se, but INVITE command does not work
2340 yet correctly, so you can set channel as invite only channel but
2341 inviting clients to the channel does not work (it is yet to be
2342 thought what's the best way to do it).
2344 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2345 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2346 Implemented CUMODE command to change user's mode on the channel.
2347 Supports all modes defined by the protocol specs.
2349 * Added NAMES command reply to return users modes on the channel.
2351 * Removed unnecessary and slow ciphers from lib/silccrypt.
2353 * Set SO_KEEPALIVE option to connection sockets by default.
2355 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2357 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2358 redefined the Notify Payload into protocol specs.
2360 * Added silc_id_payload_parse_id to get ID directly from raw
2363 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2366 accept searching by Client ID as well.
2368 * Added support for LEAVE and SIGNOFF notify types in client library.
2370 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2371 to parse ID Payload from raw data.
2373 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Added flags parameter into silc_ske_assemble_security_properties
2376 function in lib/silcske/silcske.[ch].
2378 * Changed notify client operation to fit better for notify messages
2379 sent by server. The notify payload received from server is now
2380 passed to the application (after parsing it to SilcNotifyPayload).
2381 It is application's responsibility to retrieve the arguments
2382 from the payload and show the message the way it wants. The message
2383 sent by server is implementation specific.
2385 * Changed public keys to comply with the protocol specification.
2386 Old public keys are not supported anymore and are not compatible.
2388 * Removed nickname from Channel Payload as the latest draft removed
2389 it. The client must resolve the nickname from the NAMES command
2390 reply received when it joined the channel.
2392 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2394 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Fixed some errors in protocol specification drafts.
2398 * Created lib/silccore/silcnotify.c to implement Notify Payload
2399 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2400 generic payloads described by protocol specifications. The file
2401 includes implementations for ID Payload and Argument Payload.
2403 * Changed Command Payload implementation to use the new Argument
2404 Payload. Changed command_xxxx_payload to command_payload_xxxx
2405 to comply with SILC coding conventions.
2407 * Added suppport for Argument Payload handling in Notify Payload
2408 implementation as protocol requires it. Added the new support
2409 into server and client lib as well.
2411 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Added support for multiple nicknames on same channel. [n] is
2414 added locally to the nickname if there are more than one same
2415 nicknames on the channel.
2417 * Server now sends all nicknames that matched WHOIS request.
2418 Client also shows the list received from server.
2420 * Added TOPIC command to client side. User can now set and show
2421 current topic on channel.
2423 * Added MOTD command to client and server. Also, server sends the
2424 motd when client connects to the server.
2426 * Changed version strings to comply ISO 8601.
2428 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Fixed protocol error handling in client library. It should now
2431 cope even if the SKE fails for some reason.
2433 * Made new protocol specification drafts for submitting to IETF.
2435 * Implemented TOPIC command to server in silcd/command.c.
2437 * Added two new notify types into lib/silccore/silcnotify.h:
2438 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2439 notify nickname change and topic setting/change on a channel.
2441 * API change of command_reply operation in client library. The
2442 application gets now the status type received from server as well.
2444 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2448 * Cras fixed and optimized the packet handling even further and
2449 it should work now. Minor change to the prototype of function
2450 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2452 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Added new function into lib/silcutil/silcschedule.[ch]:
2455 silc_schedule_with_fd to select() a specified fd. The function
2456 returns after timeout expires or data arrives or goes. The
2457 function is used by packet routines to wait that all data is
2458 received from network.
2460 * Fixed data reading from network in lib/silccore/silcpacket.c.
2461 The code now assures that all data is read from the fd and then
2462 continues packet processing. This was a bug fix since the code
2463 used to drop some data in some circumstances.
2465 * Added new function into lib/silcclient/client.[ch]:
2466 silc_client_start_key_exchange to start key exchange after
2467 connection has been established to server. The code internally
2468 now uses this funtion but its main purpose was to provide it
2469 for applications that perform their own connecting. After
2470 application has created a connection it merely calls this
2471 function to start the key exchange between client and server.
2472 The library takes care of everything else after that.
2474 Updated also lib/silcclient/README to explain the usage of
2477 * Do not send to application information that connection has
2478 been established. Application gets notified it by connect
2481 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Applied cras's patch to add silc_schedule_one function. The
2484 function runs scheduler once and returns.
2486 * Fixed the scheduler after cras messed it up. The timeout
2487 handling works now as it's supposed to work.
2489 * Added into lib/silccore/ silcnotify.h to include notify
2490 message types support. Changed silc_server_send_notify*
2491 functions, in server.[ch], to support those new notify types.
2492 Added the support for the notify types into client library,
2493 as well. Added new notify client operation into ops.h in
2496 * Changed silc_server_packet_send_to_channel to send normal
2497 packets instead of just channel message packets. The function
2498 is now used to send the notify packets to channels. It is not
2499 used to send channel message packets anymore, as server never
2502 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2503 va_arg()s as it seems to require it nowadays. I guess, if SILC
2504 is compiled with older va_arg() the new code should work anyway.
2506 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Splitted core library. Core library (lib/silccore) includes
2509 now only SILC protocol specific core (and common) components.
2510 Created new utility library (lib/silcutil) that includes more
2511 generic purpose stuff. The stuff for util library was taken
2512 from the old core library. This was minor and easy split.
2514 * Created SILC Client Library (lib/silcclient) that includes
2515 implementation of the SILC client without user interface. This
2516 was major move from silc/ directory. The code has been changed
2517 so that it is transparent towards the user interface. The
2518 silc/ directory includes now the same user interface as before
2519 and it uses the new client library. Read lib/silcclient/README.
2520 Basicly, the client library performs everything else related
2521 to SILC except user interface handling. Also, configuration
2522 files are considered to be part of user interface and library
2523 does not handle them.
2525 This change also changed a lot of structures, function naming etc.
2526 Most important change was that SilcClientWindow object was
2527 renamed to SilcClientConnection in the client library. Created
2528 also new file lib/silcclient/ops.h. Also added new files
2529 silc/local_command.[ch] and silc/client_ops.[ch].
2531 All these changes were made to make it easier for user interface
2532 designers to create what ever user interface for the SILC client
2535 It is also expected that the server will be moved to lib
2536 directory as well and SILC Server Library will be created;
2537 sometimes in the future.
2539 * Removed Local commands from lib/silccore/silccommand.h as
2540 they are application specific and new client library does not
2541 handle any of those anymore.
2543 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2544 old client implementation in silc/.
2546 * Added support for callback functions in SILC_LOG_* macros.
2547 Application can now set its own callbacks that will be called
2548 instead of using the default functions that will always print
2549 the debug messages to stderr (or stdout). Also, debugging can
2550 now be disabled by setting silc_debug to FALSE and re-enabled by
2551 setting it to TRUE. Note, that logging will still work even
2552 if debugging is disabled.
2554 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2555 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2556 silc_log_reset_debug_callbacks.
2558 * To enable debugging in silc client one must give now -d
2559 option on command line.
2561 * Changed silc_schedule_init to automatically allocate task queues
2562 if they are not allocated before calling it.
2564 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Added GMP 3.1 into math library.
2568 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2571 a channel in SILC network. The packet is used by servers and
2572 routers to notify other routers that user has left a channel.
2573 This little feature was missing until now. Added the feature
2574 to protocol specification as well.
2576 Added functions: silc_server_send_remove_channel_user and
2577 silc_server_remove_channel_user into server.[ch].
2579 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2580 lib/silccore/silcpacket.h. However, they are not implemented
2583 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Fixed joining to a channel and sending channel messages
2586 between server and router. The channel message sending should
2587 now work inside a cell.
2589 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Fixed the private message sending between server and router.
2592 The private message sending should now work inside a cell.
2594 * Added silc_server_replace_id into server.[ch] to replace
2595 existing ID in the SILC network.
2597 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2598 and silc_idlist_replace_server_id into idlist.[ch] in server.
2600 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Fixed the server to server connections. Server can again now
2603 connect to router. Router to router connections probably does
2606 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Added dynamic protocol registering support. Now protocols can
2609 registered and unregistered on the fly. Patch by cras.
2611 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Added lib/contrib directory to hold routines that some platforms
2614 don't have but are needed by SILC.
2616 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2617 into lin/contrib to provide getopt() and getopt_long() for
2618 those who don't have it.
2620 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Added AWAY command to client. When away message is set and
2623 client receives a private message packet the client automatically
2624 replies to the sender with the away message.
2626 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2627 bug seemed to be the cause of recent problems when compiling
2630 * Added version detection support to SKE protocol specification
2631 and added the new changes to the SKE implementation as well.
2632 There were other minor changes in the SKE protocol as well.
2634 Many changes in lib/silcske/silcske.[ch] and in
2635 lib/silcske/payload.[ch].
2637 * Added ^U functionality, clear input line. Patch from cras.
2639 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Mainly small bugfixes on core library. Fixed some debugging
2642 logging and buffer overflow in silclog.c.
2644 * Updated config.sub and config.guess on the distribution tree.
2646 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added command lagging support in server. Client may execute
2649 commands now only once in two seconds.
2651 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Optimized packet reception. MAC computation and checking is now
2654 also more optimized. A lot previously duplicated code is now
2655 used as generic by both client and server.
2657 * Fixed key pair generation in clientutil.c
2659 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added into lib/silccore/silcbufutil.[ch] new function;
2662 silc_buffer_realloc.
2664 * Moved generic packet sending/encryption functions to
2665 lib/silccore/silcpacket.[ch] from client and server. Some
2666 rewriting of the functions.
2668 * Moved all generic packet reception/decryption functions to
2669 lib/silccore/silcpacket.[ch] from client and server. The
2670 packet processing is now much cleaner in both client and server.
2671 These were major changes in both client and server.
2673 * Created many common functions in server to do packet sending.
2674 Previously code were duplicated a lot, this has been removed
2677 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Rewrote major parts of the ID cache system. Don't know
2680 whether it is better now or not but at least the API is more
2683 * Major rewrite on ID cache stuff on client because of the ID
2684 cache API changes. Added idlist.c to client.
2686 * Also major rewrite on ID cache stuff on server as well.
2687 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2688 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2689 in hand, instead they are all put into the ID cache system now.
2690 All server_idlist_* routines uses ID cache now instead of
2691 traversing its own lists (those lists does not exist anymore).
2692 SilcIDList though still exists. Also, SilcXXXEntry's are
2695 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Finally made the SKE implementation compliant to the protocol
2698 specification. All mp integers are now binary encoded as
2699 opposed being HEX encoded.
2701 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2704 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2705 functions: silc_[encode/decode]_pem. Also added function
2706 silc_encode_pem_file to PEM encode with newlines ('\n') for
2709 * SILC public keys are now encoded either PEM or binary. Same
2710 option is for private keys as well. By default private keys
2711 are binary encoded and public keys PEM encoded. Silly HEX
2712 encoding were removed.
2714 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2715 function to create fingerprints.
2717 * Fixed a bug in SHA1; does not change the original data anymore.
2719 * Partly implemented INFO command on client and server side.
2720 Fixed CLEAR command. Changes to SERVER command; show current
2721 server(s) when giving command without arguments. Added
2722 VERSION command to client.
2724 * Added check to server that unregistered connections cannot
2725 execute commands (unless it is specificly allowed).
2727 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Fixed screen refresh.
2731 * Fixed channel joining bug from client. On some circumstances
2732 client tried to join to a channel it had already joined.
2734 * Added public key verification process into client's protocol.c.
2735 The client now verifies the public key from user and saves
2736 it into ~./silc/serverkeys/ directory.
2738 Added into: clientutil.[ch]: silc_client_verify_server_key.
2740 * Changed SKE protocol's silc_ske_initiator_finish function
2741 to accept callback function that verifies the received public
2742 key. Removed old silc_ske_verify_public_key function.
2744 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2747 silc_pkcs_private_key[_data]_set.
2749 * Made the password and public authentication more cleaner in
2750 server's protocol.c.
2752 * Removed historic and obsolete protocol `channel_auth' from
2753 both client and server.
2755 * Removed wrong way of sending command status messages from
2756 server to client in server's command.c. The old way violated
2757 protocol specification.
2759 Changes to silccore/silccommand.[ch]: removed
2760 silc_command_encode_status_payload -> not needed anymore,
2761 changed silc_command_encode_payload_va to accept extra
2762 argument on variable argument list. The argument type must
2763 now be provided to the function. Also, added new function:
2764 silc_command_encode_reply_payload_va which is same as
2765 normal command_encode_payload_va except command status type
2766 is provided as extra argument.
2768 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Added ~./silc directory handling. The directory includes the
2771 public and private keys for the client.
2773 Added silc_client_check_silc_dir, silc_client_create_identifier
2774 and silc_client_load_keys.
2776 * Implemented SILC protocol compliant public key. Added public
2777 and private key saving to and loading from files.
2779 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2780 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2781 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2782 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2783 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2785 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2786 silc_pkcs_load_[public/private]_key.
2788 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Added silc_server_get_route (route.[ch]) to get connection
2791 data for the fastest route for given ID.
2793 * Implemented INVITE command on client and server. The command
2794 were re-defined in the SILC Protocol Specification and the
