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

127 notify between routers.
129 * Implemented the INVITE command correctly to the server.
131 * Implemented the INVITE notify type handling in the server.
133 * Implemented the INVITE command to the client library and on the
136 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Added function silc_server_get_client_resolve to find the
139 client entry by ID from all ID lists and then resolve it
140 (using WHOIS) if it cannot be found. Affected file is
143 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Implemented the BAN command to the client library.
147 * The JOIN command in the server now checks the invite list
150 * Changed the silc_command_reply_payload_encode_va and the
151 silc_command_payload_encode_va to support that if argument is
152 NULL it ignores and checks the next argument. Affected file
153 lib/silccore/silccommand.c.
155 * Added silc_server_send_notify_ban to send the BAN notify
156 type between routers.
158 * Chaned the silc_notify_payload_encode to support that if
159 argument is NULL it ignores and checks the next argument.
160 Affected file lib/silccore/silcnotify.c.
162 * Tested ban lists in router environment successfully.
164 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Implemented BAN command to the server, in silcd/command.[ch].
168 * Removed the BAN and INVITE_LIST modes from the CMODE command
171 * Added function silc_string_match to regex match two strings.
172 Affected files lib/silcutil/silcutil.[ch].
174 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Redefined parts of the SilcChannelEntry in the server to support
177 the new ban and invite lists.
179 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Redefined the INVITE command. The same command can be used to
182 invite individuals to the channel but also to manage the invite
183 list of the channel (to add to and remove from the invite list).
184 Updated the protocol specs.
186 * Added new command SILC_COMMAND_BAN that can be used to manage
187 the ban list of the channel. Updated the protocol specs.
189 * Removed the channel modes: the SILC_CMODE_BAN and the
190 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
191 in the CMODE command. The equivalent features are now available
192 using INVITE and BAN commands. Updated the protocol specs.
194 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
195 in the network about change in the current ban list. The notify
196 type is not used by the client.
198 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
199 support the invite lists.
201 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Added new function silc_string_regexify that converts string
204 including wildcard characters into regex string that can
205 be used by the GNU regex library. Added into the file
206 lib/silcutil/silcutil.[ch].
208 Added silc_string_regex_combine to combine to regex strings
209 into one so that they can be used as one regex string by
210 the GNU regex library. Added into the file
211 lib/silcutil/silcutil.[ch].
213 Added silc_string_regex_match to match two strings. It returns
214 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
216 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Imported GNU regex to the soruce tree into lib/contrib.
219 Fixed some compiler warning from the regex.c.
221 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Fixed MOTD command in the server to work in router environment.
225 * Fixed the MOTD command in the client library to support
226 the server argument in the command.
228 * Added `nickname_len' argument to the silc_idlist_add_client
229 in the server, as the `nickname' argument may be binary data
232 * Added silc_idlist_get_channels to return all channels from
235 * Implemented LIST command to the server. Affected file is
238 * Implemented the LIST command to the client library and on the
241 * Added [<user count>] argument to the LIST command reply.
242 With private channels the user count is not shown.
244 * Updated TODO and README.
246 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * The client entry's data.registered must be TRUE even with
249 global client entry on global client list. The data.registered
250 is used to check whether the client is anymore in the network,
251 for example with WHOWAS command so it must be valid.
253 * Fixed the WHOWAS command in the server. It now actually works
254 in router environment. Added function into silcd/command_reply.c
255 silc_server_command_reply_whowas_save.
257 * Added silc_idlist_purge function to the silcd/idlist.c
258 to periodically purge the ID Cache.
260 * Fixed INFO command in the server. It works now in router
261 environment. Added <server name> argument to the INFO command
262 reply. Updated the protocol specs.
264 * Fixed minor bug in silc_idcache_purge to not purge if the
265 expire value is zero.
267 * Fixed various bugs in WHOIS and IDENTIFY command handling as
268 they were buggy because of the WHOWAS information.
270 * Fixed local command MSG to handle the async resolving of
271 the remote client properly. It used to fail the first MSG.
272 Affected file silc/local_command.c.
274 * Added `data_len' field to SilcIDCache context.
276 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Update TODO. Todo in commands in the server.
280 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
283 used by routers as broadcast packet to inform other routers
284 about the changed user mode.
286 Implemented the notify handling in the server. Affected file is
287 silcd/packet_receive.c. Added the function
288 silc_server_send_notify_umode to the silcd/packet_send.[ch].
290 * Added new generic Channel Payload and deprecated the New Channel
291 Payload. The New Channel Payload is now the generic Channel
294 * Added new argument `mode' to the silc_server_send_new_channel
295 as it is required in the Channel Payload now.
297 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
298 and created a new and real SilChannelPayload to represent the
299 new generic Channel Payload. Implemented the encode/decode
300 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
302 * Added silc_server_get_client_channel_list to return the list
303 of channels the client has joined for WHOIS command reply.
304 Affected file silcd/server.[ch].
306 * Implemented the channel list sending in the WHOIS command reply
307 in server and in the client.
309 Implemented the channel list displaying on the user interface
310 as well. Affected file silc/client_ops.c.
312 * Added silc_channel_payload_parse_list to parse list of Channel
313 Payloads. It returns SilcDList list of SilcChannelPayloads.
314 Client for example can use this function to parse the list of
315 channels it receives in the WHOIS command reply. The caller
316 must free the list by calling silc_channel_payload_list_free.
317 Affected files lib/silccore/silcchannel.[ch].
319 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Added one new argument <user mode> to the WHOIS command reply
322 to return the mode of the user in SILC. Updated the protocol
325 Implemented it to the server and client.
327 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Fixed the mode printing on the user interface on joining.
330 Affected file silc/client_ops.c.
332 * Implemented the UMODE command and user modes in general to the
333 client library and to the user interface.
335 * Implemented the UMODE command to the server.
337 * The server now sends UNKNOWN_COMMAND error status if client sends
338 unknown command. Affected file silcd/command.c.
340 * All server commands now handle the command identifier the right
341 way when sending the command reply to the client. The client can
342 use to identify the command replies with the identifier.
344 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Added silc_server_get_client_route to resolve the route to
347 the client indicated by the client ID. Affected file is
350 * Added silc_server_relay_packet as general function to relay
351 packet to arbitrary destination. This deprecates functions
352 like _send_private_message_key, _relay_notify etc. Affected
353 file is silcd/packet_send.[ch].
355 Removed silc_server_send_key_agreement,
356 silc_server_send_private_message_key and
357 silc_server_packet_relay_notify functions from the file
358 silcd/packet_send.[ch].
362 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
363 server. Affected file silcd/packet_receive.[ch].
365 * Implemented the KILL command to the client. Implemented the
366 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
367 Affected files lib/silcclient/command[_reply].c and
368 lib/silcclient/client_notify.c. Implemented the KILL notify
369 printing in the user inteface.
371 * Fixed a lot silc_parse_nick memory leaks from the client
372 library in the file lib/silcclient/command.c.
374 * Changed the silc_server_send_notify_on_channels's `sender'
375 argument from SilcSocketConnection to SilcClientEntry to
376 check the sender as entry and not as connection object and not
377 to send to the client provided as argument. The affected file
378 is silcd/packet_send.[ch].
380 * The notify packets that are destined directly to the client used
381 to not to be processed by the server. Now changed that and the
382 server processes all notify packets. After relaying the packet
383 to the client the notify packet is processed in the server.
385 * The silc_server_free_client_data now checks whether there is
386 pending outgoing traffic for the client and purges the data to
387 the network before removing the client entry.
389 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
392 an client is killed from the SILC Network. Updated the protocol
395 Added new function silc_server_send_notify_killed to the
396 silcd/packet_send.[ch].
398 * Added function silc_server_packet_relay_notify to relay notify
399 packets that are destined directly to a client. In this case
400 the server does not process the notify packets but merely relays
401 it to the client. Affected file silcd/packet_send.[ch].
403 Added also silc_server_packet_process_relay_notify to check
404 whereto relay the notify. Affected file is
405 silcd/packet_receive.[ch].
407 * Implemented the KILL command to the server.
411 * Added the backup schema desgined last fall to the protocol
412 specs for everyone to see. The specification is in the
413 *-spec-xx.txt draft and the packet type definitions for the
414 backup routers is in *-pp-xx.txt draft. Thusly, added also
415 new packet type SILC_PACKET_CELL_ROUTERS.
417 * A big security problem in the implementation discovered. The
418 signoff of an client did not cause new channel key generation
419 which it of course should've done. The channel keys must be
420 always re-generated when client leaves (or signoffs) the channel.
421 The silc_server_remove_from_channels funtion now handles
422 the channel key re-generation.
424 * Added `sender' argument to the silc_server_send_notify_on_channels
425 to not to send the client provided as argument. Affected file
426 silcd/packet_send.[ch].
428 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Implemented OPER and SILCOPER commands into the server and
433 * Added silc_auth_verify and silc_auth_verify_data to verify
434 the authentication directly from the authentication payload.
435 It supports verifying both passphrase and public key based
436 authentication. Affected file lib/silccore/silcauth.[ch].
438 * Added `hash' field to the SilcIDListData structure. It is the
439 hash negotiated in the SKE protocol. Affected file is
442 * Slight redesigning of the SilcAuthPayload handling routines.
443 Do not send SilcPKCS but SilcPublicKey as argument.
445 * Implemented the public key authentication support to the
446 serverconfig. The public key is loaded from the provided path
447 and saved as authentication data to void * pointer. Thus,
448 changed the unsigned char *auth_data to void *auth_data;
450 * Fixed SHUTDOWN command to send the reply before the server
451 is shutdown. :) Affected file silcd/command.c.
453 * Fixed fatal bug in CONNECT command. The hostname was invalid
454 memory and server crashed. Affected file silcd/command.c.
456 * Fixed fatal bug in CLOSE command. The server_entry became
457 invalid but was referenced later in the command. Affected file
460 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Fixed fatal bug in failure packet handling. Server ignored
463 the failure and thus crashed when it came.
467 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
470 that the command may be executed only once in (about) 2 seconds.
471 The old SILC_CF_LAG flag is same but allows command bursts up
472 to five before limiting.
474 Added the support for CF_LAG and CF_LAG_STRICT flags to the
475 server code. Various commands now includes the CF_LAG_STRICT
476 flag to disallow any kind of miss-use of the command.
478 * Fixed the silc_buffer_unformat to not to allocate any data
479 if the length of the data is zero. It used to allocate the
480 length + 1. Affected file lib/silcutil/silcbuffmt.c.
482 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Changed the format of AdminConnection configuration section
485 in the server. Added username of the admin to the format.
486 Affected files silcd/serverconfig.[ch].
488 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
489 to return admin configuration data by host, username and/or
492 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Implemented WHOWAS command to the server. Added the functions:
496 silc_server_command_whowas_parse,
497 silc_server_command_whowas_send_reply,
498 silc_server_command_whowas_from_client and
499 silc_server_command_whowas_from_server
501 * Added <Client ID> argument to the WHOWAS command reply. Updated
502 the protocol specs accordingly.
504 * Implemented WHOWAS command and command_reply to the client
507 Implemented the WHOWAS printing on the user interface.
509 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Added new argument to the WHOWAS command reply, the real name.
512 It is an optional argument. Updated the protocol specs.
514 * Added SilcIDCacheDestructor callback that is registered when
515 the SilcIDCache is allocated. The callback is called when
516 an cache entry in the ID Cache expires, or is purged from the
517 cache. Added into lib/silccore/idcache.[ch].
519 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
520 to destruct the client entries when the cache entry expires.
521 Other ID Cache's in server and in the client library ignores
524 * If the ID Cache entry's `expire' field is zero then the entry
525 never expires. Added boolean `expire' argument to the
526 silc_idcache_add function in the lib/silccore/idcache.[ch].
527 If it is TRUE the default expiry value is used.
529 * Added silc_server_free_client_data_timeout that is registered
530 when client disconnects. By default for 5 minutes we preserve
531 the client entry for history - for WHOWAS command.
533 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Added support to the server to enforce that commands are not
536 executed more than once in 2 seconds. If server receives
537 commands from client more frequently, timeout is registered
538 to process the commands. Affected file silcd/command.c.
539 Added new function silc_server_command_process_timeout.
541 * Changed NICK_NOTIFY handling in client library to check that
542 if the client's nickname was changed, so there is no need to
543 resolve anything from the server.
545 * Removed error printing from the WHOIS and IDENTIFY commands.
546 If error occurs then it is ignored silently in the client library.
547 The application, however, may map the received error to
548 human readable error string. The application currently maps
549 the NO_SUCH_NICKNAME error to string.
551 * Made the command status message public to the application. Moved
552 them from lib/silcclient/command_reply.c to
553 lib/silcclient/command_reply.h. The application can map the
554 received command status to the string with the
555 silc_client_command_status_message function.
557 * Added check to the server to check that client's ID is same
558 as the Source ID in the packet the client sent. They must
561 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Added dist-bzip hook to the Makefile.am to make bzip2
564 compressed distributions.
566 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Server now enforces the maximum length for the nickname and
569 the channel as protocol specification dictates. 128 bytes for
570 nickname and 256 bytes for channel name.
572 * Moved the WHOIS printing to the application. The client libary
573 does not print out the WHOIS information anymore, the application
574 must do it. Renamed silc_client_command_reply_whois_print to
575 the silc_client_command_reply_whois_save.
577 The client's idle time is also sent to the application now, and
578 the idle is shown on screen.
580 * Added silc_client_command_reply_identify_save to save the
581 received IDENTIFY entries.
583 * Do not check for channel private keys in message sending and
584 reception if the channel does not have the PRIVKEY mode set.
585 Affected file lib/silclient/client_channel.c.
587 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
590 just surfaced after chaning the JOIN procedure.
592 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Added silc_client_get_clients_by_list to get client entries
595 from Client ID list, that is returned for example by JOIN
596 and USERS command replies. The application should use this
597 function for example when JOIN command reply is received to
598 resolve the clients already on the channel (library does not
599 do that anymore as USERS command reply is not used in the JOIN
600 procedure anymore). Affected files lib/silcclient/silcapi.h and
601 lib/silcclient/idlist.c.
603 * JOIN command reply and USERS command reply returns now SilcBuffer
604 pointers instead of unsigned char pointers when returning
605 the client list and mode list.
607 * Added <Client ID> argument to the JOIN command reply, mainly
608 for the server to identify for which client the command was
609 originally sent. Updated protocol specs accordingly.
611 * Added SilcDlist private_key pointer to the SilcChannelEntry
612 in the client to support the channel private keys. Affected
613 file is lib/silcclient/idlist.h.
615 * Added SilcChannelPrivateKey argument to the function
616 silc_client_send_channel_message so that application can choose
617 to use specific private ke if it wants to. If it is not provided,
618 the normal channel key is used, unless private keys are set.
619 In this case the first (key that was added first) is used
620 as the encryption key.
622 * Implemented the support for channel private key handling.
623 Implemented the following functions:
625 silc_client_add_channel_private_key,
626 silc_client_del_channel_private_keys,
627 silc_client_del_channel_private_key,
628 silc_client_list_channel_private_keys and
629 silc_client_free_channel_private_keys
631 Affected file lib/silcclient/client_channel.c.
633 * Added the support for the private keys in the channel message
634 sending and encryption and in the message reception and
635 decryption. Affected funtions are
636 silc_client_send_channel_message and silc_client_channel_message.
638 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Added SKE's key verify callback to the client library's
641 KE protocol context. Affected files lib/silcclient/protocol.[ch].
643 * Removed the statement that server (or router) must send USERS
644 command reply when joining to the channel so that the client
645 knows who are on the channel. Instead, the client list and
646 client's mode list is now sent in the JOIN command reply to the
647 client who joined channel. This is better solution.
649 * Added function silc_server_get_users_on_channel and function
650 silc_server_save_users_on_channel to the silcd/server.[ch].
652 * Removed function silc_server_command_send_users from the
655 * Do not show topic on the client library anymore. The topic is
656 sent in the command reply notify to the application and the
657 application must show the topic now.
659 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Added client searching by nickname hash into the IDENTIFY and
662 WHOIS commands in the server as they were clearly missing from
663 them. Affected file is silcd/command.c.
665 * Fixed a bug in private message receiving in the client library.
666 The remote ID was freed and it wasn't supposed, now it is
669 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Minor fix to the channel payload; allocate the data area, as it
672 needs to be of specific length.
674 * If the key agreement port is zero then the operating
675 system will define the bound port. Affected files are
676 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
678 * Added new function silc_channel_payload_decrypt into the file
679 lib/silccore/silcchannel.[ch].
681 * Moved the channel message etc, check from silc_packet_decrypt
682 to applications. The library calls now a generic
683 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
684 when the packet is either normal or special. This was done to
685 allow more wide range of checking that was not allowed when
686 the code was in library. Now applications can do virtually any
687 checks to the packet and return to the library the decision how
688 the packet should be processed. Affected files are
689 lib/silccore/silcpacket.[ch].
691 Added silc_server_packet_decrypt_check to the server and
692 silc_client_packet_decrypt_check to the client library.
694 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
695 to send with specified source and destination information.
697 * Channel message delivery between routers was broken after the
698 channel key distribution was fixed earlier. The channel key
699 was used be to distributed to other routers as well which is not
700 allowed by the protocol. Now this is fixed and channel keys
701 really are cell specific and the channel message delivery between
702 routers comply with the protocol specification.
704 * Fixed various commands in server to check also the global list
705 for the channel entry and not just the local list. The affected
706 file silcd/command.c.
708 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
710 * Added assert()s to buffer formatting and unformatting routines
711 to assert (if --enable-debug) when error occurs. Affected
712 file: lib/silcutil/silcbuffmt.c.
714 * Changed to auto-reconnect to check whether the remote host is
715 router and register the re-connect timeout if it is. It used
716 to check that whether we are normal server, but router must do
717 auto-reconnect with another router as well. Affected file
720 * Removed the [<key len>] option from CMODE command as the cipher
721 name decides the key length, nowadays. See the defined ciphers
722 from the protocol specification.
724 * Added [<hmac>] option to the CMODE command to define the HMAC
725 for the channel. Added SILC_CMODE_HMAC channel mode.
727 * Added [<hmac>] option for the JOIN command so that user can
728 select which HMAC is used to compute the MACs of the channel
731 * Added Hmac field to the Channel Message Payload. The integrity
732 of plaintext channel messages are now protected by computing
733 MAC of the message and attaching the MAC to the payload. The
734 MAC is encrypted. Now, it is clear that this causes some
735 overhead to the size of the packet but rationale for this is that
736 now the receiver can verify whether the channel message decrypted
737 correctly and also when private keys are set for the channel the
738 receiver can decrypt the packet with several keys and check from
739 the MAC which key decrypted the message correctly.
741 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
742 lib/silccrypt/silccipher.[ch].
744 * Added silc_hash_len to return the digest length into the
745 lib/silcrypt/silchash.[ch].
747 * Rewrote parts of Silc Channel Payload interface in the
748 lib/silccore/silcchannel.[ch]. The encode function now also
749 encrypts the packet and parse function decrypts it.
751 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Fixed a minor formatting bug in the SKE's key material processing.
754 It actually might have processed the keys wrong way resulting
757 * Redefined the mandatory HMAC algorithms and added new algorithms.
758 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
759 and hmac-md5 truncated to 96 bits. The mandatory is now
760 hmac-sha1-96. Rest are optional (including the one that used
761 to be mandatory). Rationale for this is that the truncated HMAC
762 length is sufficient from security point of view and can actually
763 make the attack against the HMAC harder. Also, the truncated
764 HMAC causes less overhead to the packets. See the RFC2104 for
767 * Added new [hmac] configuration section. The SKE used to use
768 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
769 is of course wrong. The official names that must be proposed in
770 the SKE are the ones defined in the protocol specification
771 (hmac-sha1-96 for example). The user can configure any hmac
772 using any hash function configured in the [hash] section. At
773 least, the mandatory must be configured.
775 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
777 * Added HMAC list to the SKE proposal list. It has now both
778 hash algorithm list and HMAC list. This makes the protocol
779 incompatible with previous versions. The SKE now seems to work
780 the way it is supposed to work, for the first time actually.
782 * Defined plain Hash algorithms to the protocol specification.
785 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Implemented support for key agreement packets into the server.
788 Added functions silc_server_key_agreement and
789 silc_server_send_key_agreement. Other than these functions,
790 server has nothing to do with this packet.
792 * Added support for private message key packets into the server.
793 Added functions silc_server_private_message_key and
794 silc_server_send_private_message_key.
798 * Changed the silc_[client|server]_protocol_ke_set_keys to be
799 called in the protocol's final callback instead in the END
800 protocol state. This makes a little more sense and in the same
801 time in client we can use the same protocol routines for normal
802 key exchange and to key agreement packet handling as well.
804 * Added to both client's and server's KE protocol context the
805 SilcSKEKeyMaterial pointer to save the key material. We will
806 bring the key material to the protocol's final callback by doing
807 this. The final callback must free the key material.
809 * Added SKE's packet_send callback into client's KE protocol
810 context so that the caller can choose what packet sending function
811 is used. This way we can use different packet sending when
812 doing normal SKE when doing key agreement packet handling (in
813 the key agreement packet handling we do not want to encrypt
816 * Implemented the responder side of the key agreement routines
817 in the client. The client can now bind to specified port and
818 accept incoming key negotiation. The key material is passed
819 to the application after the protocol is over.
821 * Implemented the processing of incoming Key Agreement packet
822 in the client. Added function silc_client_key_agreement to
825 * Implemented the intiator side of the key agreement routines
826 in the client. The client can now initiate key agreement with
827 another remote client. The key material is passed to the
828 application after the protocol is over.
830 * Created client_keyagr.c to include all the key agreement
833 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
834 SILC_TASK_CALLBACK except that it is not static.
836 * Created client_notify.c and moved the Notify packet handling
837 from the client.[ch] into that file.
839 * Created client_prvmsg.c and moved all private message and
840 private message key routines from the client.[ch] into that file.
842 * Create client_channel.c and moved all channel message and
843 channel private key routines from the client.[ch] into that file.
845 * Changed silc_client_get_client_by_id_resolve to resolve with
846 WHOIS command instead of IDENTIFY command, in the file
847 lib/silclient/idlist.c.
849 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Implemented the SKE's responder side to the Client library.
853 * When FAILURE is received to the protocol do not trust it
854 blindly. Register a timeout to wait whether the remote closes
855 the connection as it should do it, only after that process the
856 actual failure. This was changed to both client and server.
858 * Added client_internal.h to include some of the structures
859 there instead of client.h in lib/silcclient/.
861 * Added function silc_task_unregister_by_callback to unregister
862 timeouts by the callback function.
864 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Some "Incomplete WHOIS info" errors has been appearing on the
867 log files. Took away the entry->userinfo check from WHOIS
868 reply sending. The entry->userinfo is now " " if client did not
869 provide one. I thought this was fixed earlier but something
870 is wrong still. Let's see if the error still appears.
872 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Fixed a minor bug in the login when the channel key is
875 re-generated in the server. It used to generate the key in
876 wrong order and thus caused problems in the channel traffic.
878 * Fixed a minor bug in channel key distsribution after
879 KICK command. The key was not sent to the router even though
882 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Added silc_ske_process_key_material_data as generic routine
885 to process any key material as the SILC protocol dictates. The
886 function is used by the actual SKE library but can be used by
887 applications as well. This relates to the private message keys
888 and the channel private keys since they must be processed the
889 same way the normal SILC session keys. The protocol dictates
890 this. Affected files: lib/silcske/silcske.[ch].
892 Added also silc_ske_free_key_material to free the
893 SilcSKEKeyMaterial structure.
895 * Defined silc_cipher_set_key function to set the key for
896 cipher without using the object's method function. The affected
897 files: lib/silccrypt/silccipher.[ch].
899 * Implemented silc silc_client_add_private_message_key,
900 silc_client_add_private_message_key_ske,
901 silc_client_del_private_message_key,
902 silc_client_list_private_message_keys and
903 silc_client_free_private_message_keys functions in the
906 Added functions silc_client_send_private_message_key to send
907 the Private Message Key payload and silc_client_private_message_key
908 to handle incoming Private Message Key payload.
910 * Added Cipher field to the Private Message Key payload to set
911 the cipher to be used. If ignored, the default cipher defined
912 in the SILC protocol (aes-256-cbc) is used.
914 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Removed lib/silcclient/ops.h file.
918 Redefined parts of the SILC Client Library API. Created new
919 file silcapi.h that deprecates the ops.h file and defines the
920 published Client Library API. Defined also private message key
921 API and channel private key API into the file.
923 This is the file that the application must include from the
924 SILC Client Library. Other files need not be included by
925 the application anymore.
927 * Added new key_agreement client operation callback and also
928 defined the Key Agreement library API for the application.
930 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
933 is used by clients to request key negotiation between another
934 client in the SILC network. If the negotiation is started it
935 is performed using the SKE protocol. The result of the
936 negotiation, the secret key material, can be used for example
937 as private message key.
939 Implemented the Key Agreement payload into the files
940 lib/silccore/silauth.[ch].
942 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Redefined ciphers for the SILC protocol. Added some new ciphers
945 and defined the key lengths for the algorithms. Changed the
946 code accordingly. The default key length is now 256 bits.
948 * Fixed SKE key distribution function silc_ske_process_key_material
949 when the key length is more than 128 bits. The default key
950 length in SILC is now 256 bits.
952 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
953 to indicate unsupported algorithm.
955 * Renamed rijndael.c to aes.c and all functions as well.
957 * Fixed a long standing channel key setting bug in client library.
958 Weird that it has never surfaced before.
960 * Fixed bug in channel deletion. If the entire channel is removed
961 then it must also delete the references of the channel entry
962 from the client's channel list as the client's channel entry and
963 the channel's client entry share same memory.
965 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Implemented CONNECT and SHUTDOWN commands in the client.
969 * Implemented CLOSE command to the client.
971 * Added the function silc_idlist_find_server_by_name into the
972 files silcd/idlist.[ch].
974 Added the function silc_idlist_find_server_by_conn into the
975 files silcd/idlist.[ch].
977 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * DIE command was renamed to SHUTDOWN. Updated the both code
982 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
983 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
985 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
988 * Added function silc_server_create_connection function to create
989 connection to remote router. My server implementation actually
990 does not allow router to connect to normal server (it expects
991 that normal server always initiates the connection to the router)
992 so the CONNECT command is only good for connecting to another
995 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
998 or some other client was kicked from the channel.
1000 Implemented the handling of the notify type to both client
1003 Implemented silc_server_send_notify_kicked to send the KICKED
1004 notify. It is used to send it to the server's primary router.
1006 * Implemented the KICK command into server and client.
1008 * Added `query' argument to the silc_idlist_get_client function
1009 to indicate whether to query the client from server or not if
1012 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1013 to indicate that the client is not channel founder.
1017 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Removed the rng context from SilcPacketContext structure and
1020 changed that the packet routine uses the Global RNG API.
1022 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Added support for quit message that client can "leave" on the
1025 channel when it quits the SILC. It is ditributed inside the
1026 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1028 Added silc_server_free_client_data that will take the
1029 signoff message as argument.
1031 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1033 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Updated parts of the protocol specification to keep it up
1038 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1041 payloads in one packet.
1043 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1044 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1045 use now the new List flag.
1047 * Also deprecated the following packet types: REPLACE_ID,
1048 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1050 * Added list support for Notify packet in server.
1052 * Added silc_server_send_notify_channel_change to send the
1053 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1054 the silc_server_send_replace_id.
1056 * Added silc_server_send_notify_nick_change to send the
1057 NICK_CHANGE notify type. Deprecates the function
1058 silc_server_send_replace_id.
1060 * Added silc_server_send_notify_join to send the JOIN notify type.
1061 Deprecates the function silc_server_send_new_channel_user.
1063 * Added silc_server_send_notify_leave to send LEAVE notify type.
1064 Deprecates the function silc_server_send_remove_channel_user.
1066 * Added silc_server_send_notify_cmode and
1067 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1068 types. Deprecates the silc_server_send_set_mode function.
1070 * Added SERVER_SIGNOFF notify type to indicate that server has
1071 quit. This means that all clients on the channel from that
1072 server will drop. This can be also used when netsplit happens.
1074 Deprecated REMOVE_ID packet type since it is not needed anymore
1077 Added silc_server_send_notify_server_signoff to send the
1078 SERVER_SIGNOFF notify type. Deprecates the function
1079 silc_server_send_remove_id.
1081 Added also silc_server_send_notify_signoff to send the
1082 SIGNOFF notify type.
1084 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1085 SILC protocol from this day on. Changed the protocol
1086 specification as well.
1088 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1089 notify type. It is used between routers to notify about
1090 topic changes on a channel.
1092 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1095 * Partly updated the protocol specification to comply with the
1096 changes now made. It is still though a bit outdated.
1098 * The JOIN notify type now takes one extra argument <Channel ID>.
1099 The packet used to be destined to the channel but now the
1100 JOIN type may be sent as list thus it is impossible to
1101 destine it to any specific channel. By adding this argument
1102 it is again possible.
1104 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * Added CREDITS file. The CHANGES and CREDITS file will appear
1107 in the distribution as well.
1109 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1111 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1112 types in the server's silcd/packet_receive.c.
1114 * Implemented CMODE and CUMODE to work in router environment.
1116 * Fixed minor encoding and decoding buglet from the
1117 lib/silccore/silcmode.c.
1119 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1122 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1124 * Changed all SilcConfigServer* and silc_config_server* to
1125 SilcServerConfig* and silc_server_config*, respectively.
1128 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Associated the ID (client or server ID) to the Authentication
1131 Payload to avoid any possibility of forging. Updated the
1132 protocol specification and the code accordingly.
1134 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1136 * The RSA key length is now save to the RsaKey context in the
1137 key generation process in lib/silccrypt/rsa.c. The key length
1138 is now used to figure out the maximum size of the block allowed
1139 to be encrypted/signed.
1141 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1142 is equivalent to the silc_mp_mp2bin but does not allocate any
1145 * Changed silc_mp_mp2bin API to take length argument. If it is
1146 non-zero then the buffer is allocated that large. If zero, then
1147 the size is approximated using silc_mp_sizeinbase, which however
1150 * Created Global RNG API which is global RNG that application can
1151 initialize. After initializing, any routine anywhere in the
1152 code (including library) can use RNG without allocating a new
1153 RNG object. This was done to allow this sort of use of the
1154 RNG in code that has no chance to allocate RNG object. All
1155 applications currently allocate this and many routines in the
1156 library use this. Affected file lib/silccrypt/silcrng.[ch].
1158 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1159 it to use the Global RNG API.
1161 * Defined Authentication Payload into protocol specification that
1162 is used during SILC session to authenticate entities. It is
1163 used for example by client to authenticate itself to the server
1164 to obtain server operator privileges.
1166 Implemented this payload into the lib/silccore/silcauth.[ch].
1167 Implemented also routines for public key based authentication
1168 as the new protocol specification dictates.
1170 Moved definitions of different authentication methods from
1171 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1173 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1174 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1175 silc_pkcs_verify_with_hash functions into the file
1176 lib/silccrypt/silcpkcs.[ch].
1178 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * The client entry's userinfo pointer must be always valid.
1181 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1182 will fail since it requires the userinfo. Now, the userinfo
1183 is allocated as "" if actual userinfo does not exist. Actually,
1184 it must exist and it is totally Ok to drop client connections
1185 that does not announce the userinfo. However, we will make
1186 this workaround for now.
1188 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1189 to return the remote port by socket.
1191 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1194 SILC_SERVER_PENDING_EXEC and added an new macro
1195 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1196 data or when error occurs while processing the pending command.
1198 Added new argument `destructor' into silc_server_command_pending
1199 and to the SilcServerCommandPending object. This destructor is
1200 now called after calling the pending callback or if error occurs
1201 immediately. If error occurs the actual pending callback won't
1202 be called at all - only the destructor. The destructor may be
1203 NULL if destructor is not needed.
1205 All this applies for client library code as well. Similar
1206 changes were made there as well for the pending commands.
1208 In the client, the application must now allocate the
1209 SilcClientCommandContext with the silc_client_command_alloc
1212 * Added reference counter to the SilcServerCommandContext. Added
1213 function silc_server_command_alloc and silc_server_command_dup
1216 Same type of functions added to the client library for the same
1219 * Removed the cmd_ident from IDListData away since it is now
1220 global for all connections. It is the command identifier used
1221 in command sending and with pending commands. The affected file
1224 * Added reference counter to the SilcSocketConnection objecet to
1225 indicate the usage count of the object. The object won't be
1226 freed untill the reference counter hits zero. Currently only
1227 server uses this, and client ignores it. The client must be
1228 set to use this too later. The affected files are
1229 lib/silccore/silcsockconn.[ch]. Added also the function
1230 silc_socket_dup to increase the reference counter.
1232 This was mainly added because it is possible that the socket
1233 is removed underneath of pending command or other async
1234 operation. Now it won't be free'd and proper DISCONNECTING
1235 flags, etc. can be set to avoid sending data to connection that
1236 is not valid anymore.
1238 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1239 the connection. After that it sets SILC_SET_DISCONNECTED.
1240 It is, however, possible that the socket data is not still freed.
1241 The silc_server_packet_process now checks that data is not
1242 read or written to connection that is DISCONNECTED. The socket
1243 get's freed when the reference counter hits zero.
1245 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Changed the client operation API: channel_message operation's
1248 `sender' is now the client entry of the sender, not the nickname
1249 and the `channel' is the channel entry, not the channel name.
1251 In the private_message operation the `sender' is now also the
1252 client entry of the sender not the nickname.
1254 Affected file is lib/silcclient/ops.h and all applications
1255 using the client operations.
1257 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Moved the calling of ops->connect() from connect_to_server_final
1260 into receive_new_id functin since that is the point when the
1261 client is actually allowed to send traffic to network. The
1262 affected file is lib/silcclient/client.c.
1264 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1267 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1268 (if needs broadcasting) instead of broadcasting the packets one
1269 by one which would make a burst in the network traffic.
1271 * Added `broadcast' argument to the functions in silcd/server.[ch]
1272 silc_server_create_new_channel[_with_id] to indicate whether
1273 to send New Channel packet to primary router.
1275 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Added new function into the silcd/server.[ch] files:
1278 silc_server_create_new_channel_with_id to create new channel with
1279 already existing Channel ID.
1281 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1282 lib/silccore/silcpacket.h. This packet is used t send list of
1283 Set Mode payloads inside one packet. Server uses this to set
1284 the modes for the channels and clients on those channels, that it
1285 announced to the router when it connected to it. The protocol
1286 specification has been updated accordingly.
1288 * The silc_server_new_channel did not handle the packet coming
1289 from normal server as it normally does not send that. However,
1290 when it announces its channels it does send it. Implemented
1291 the support for that.
1293 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1294 into the file lib/silccore/id.h.
1296 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Fixed memory leaks in the functions silc_idlist_del_client,
1299 silc_idlist_del_channel and silc_idlist_del_server in the file
1300 silcd/idlist.c. All of those leaked like a sieve.
1302 * Fixed some small memory leaks in the client's function
1303 silc_client_notify_by_server.
1305 * Added functions into silcd/server.c: silc_server_announce_clients,
1306 silc_server_announce_channels and silc_server_announce_server.
1307 These functions are used by normal and router server to announce
1308 to its primary router about clients, channels and servers (when
1309 router) that we own. This is done after we've connected to the
1312 These functions effectively implements the following packet types:
1313 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1314 and SILC_PACKET_NEW_ID_LIST.
1316 * Added new functions into the silcd/packet_receive.[ch]:
1317 silc_server_new_id_list, silc_server_new_channel_list and
1318 silc_server_new_channel_user_list to handle the incoming
1319 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1321 * Added support of changing Channel ID in the function
1322 silc_server_replace_id. If the server that announces a channel
1323 to the router already exists in the router (with same name but
1324 with different Channel ID), router is responsible to send
1325 Replace ID packet to the server and force the server to change
1326 the Channel ID to the one router has.
1328 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1329 client that the Channel ID has been changed by the router. The
1330 normal server sends this to the client. Client must start using
1331 the new Channel ID as the channel's ID.
1333 Implemented handling of this new type into lib/silcclient/client.c
1334 into the function silc_client_notify_by_server.
1336 * Added new function silc_idlist_replace_channel_id into the files
1337 silcd/idlist.[ch] to replace the Channel ID.
1339 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Call silc_server_command_identify_check always when processing
1342 the IDENTIFY command in silcd/command.c
1344 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1347 send keepalive packets. The packet can be sent by clients,
1348 servers and routers.
1350 Added function silc_socket_set_heartbeat into the file
1351 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1352 If not set, the heartbeat is not performed. The actual
1353 heartbeat is implemented in the low level socket connection
1354 library. However, application is responsible of actually
1357 Added silc_server_send_heartbeat to send the actual heartbeat
1358 packet into silcd/packet_send.[ch]. Server now performs
1359 keepalive with all connections.
1361 * Added silc_task_get_first function into lib/silcutil/silctask.c
1362 to return the timeout task with shortest timeout. There was a bug
1363 in task unregistration that caused problems. TODO has been
1364 updated to include that task system must be rewritten.
1366 * The client library will now resolve the client information when
1367 receiving JOIN notify from server for client that we know but
1368 have incomplete information.
1370 * Rewrote parts of silc_server_remove_from_channels and
1371 silc_server_remove_from_one_channel as they did not remove the
1372 channel in some circumstances even though they should've.
1374 * Encryption problem encountered in server:
1376 The LEAVE command used to send the Channel Key packet to the
1377 router immediately after generating it. However, the code
1378 had earlier sent Remove Channel user packet but not immediately,
1379 ie. it was put to queue. The order of packets in the router
1380 was that Channel Key packet was first and Remove Channel User
1381 packet was second, even though they were encrypted in the
1382 reverse order. For this reason, MAC check failed. Now, this
1383 is fixed by not sending the Channel Key packet immediately but
1384 putting it to queue. However, this is more fundamental problem:
1385 packets that are in queue should actually not be encrypted
1386 because packets that are sent immediately gets encrypted
1387 actually with wrong IV (and thus MAC check fails). So, packets
1388 that are in queue should be encrypted when they are sent to
1389 the wire and not when they put to the queue.
1391 However, the problem is that the current system has not been
1392 designed to work that way. Instead, the packet is encrypted
1393 as soon as possible and left to the queue. The queue is then
1394 just purged into wire. There won't be any fixes for this
1395 any time soon. So, the current semantic for packet sending
1398 o If you send packet to remote host and do not force the send
1399 (the packet will be in queue) then all subsequent packets to the
1400 same remote host must also be put to the queue. Only after the
1401 queue has been purged is it safe again to force the packet
1404 o If you send all packets immediately then it safe to send
1405 any of subsequent packets through the queue, however, after
1406 the first packet is put to queue then any subsequent packets
1407 must also be put to the queue.
1409 Follow these rules and everything works fine.
1411 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Added new function silc_server_remove_clients_by_server to
1414 remove all client entries from ID list when the server connection
1415 is lost. In this case it is also important to invalidate all
1416 client entires as they hold the invalid server entry. This
1417 fixes fatal bug when server has lost connection and will reconnect
1420 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Made some sanity checks to silc_server_daemonise like to check
1423 whether the requested user and group actually exists.
1425 * Added sanity check to SKE's silc_ske_responder_finish to check
1426 that the public and private key actually is valid.
1428 * Invalidate the client's nickname when receiving Replace ID
1429 packet and the Client ID is being replaced. This means that the
1430 server will query the nickname if someone needs it (client)
1433 * Sort the ID Cache in client library when the ID Cache data
1434 has changed (needs sorting).
1436 * Do not allow for SILC client to create several connections to
1437 several servers. The client does not support windows right now
1438 and generating multiple connections causes weird behaviour.
1440 Irssi-silc client does support windows and can handle several
1441 connections without problems, see: www.irssi.org and SILC plugin.
1443 * Fixed some places where client was added to the IDList. The
1444 rule of thumb is following (in order to get everything right):
1445 If the client is directly connected local client then the
1446 `connection' argument must be set and `router' argument must be
1447 NULL to silc_idlist_add_client function. If the client is not
1448 directly connected client then the `router' argument must
1449 bet set and the `connection' argument must be NULL to the
1450 silc_idlist_add_client function.
1452 * The funtion silc_server_packet_send_local_channel actually did
1453 not check whether the client was locally connected or not. It
1454 does that now. Fixed a bug related to LEAVE command.
1456 * Fixed Remove Channel User payload parsing bug in server's
1457 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1459 * The server's silc_server_save_channel_key now checks also the
1460 global ID list for the channel as it might not be in the local
1461 list. Fixed a bug related to LEAVE command.
1463 * Is this the end of the [<unknown>] buglet that has been lurking
1464 around for a long time? A little for loop fix in server's
1465 silc_server_command_whois_parse that is used by both IDENTIFY
1466 and WHOIS command. At least, this was a clear bug and a cause
1467 of one type of [<unknown>] buglet.
1469 * WHOIS and IDENTIFY commands call the function
1470 silc_server_command_[whois/identify]_check function even if
1471 we are not router server.
1473 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Added --with-gmp configuration option. If set the GMP
1476 is always compiled in the SILC source tree. If not set then
1477 it is checked whether the system has the GMP3 installed. If
1478 it has then the GMP won't be compiled (the system's headers
1479 and library is used), if it doesn't have it then the GMP is
1480 compiled in the SILC source tree.
1482 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Changed RSA private exponent generation to what PKCS #1
1485 suggests. We try to find the smallest possible d by doing
1486 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1487 not security fix but optimization.
1489 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Added new config entry [Identity] to fork the server and run
1492 it as specific user and group. A patch from Bostik.
1494 * Imported Dotconf configuration library into lib/dotconf.
1495 This will be used to create the SILC configuration files later.
1496 It will appear in the distsribution after this commit.
1498 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * A big code auditing weekend happening. Auditing code for
1501 obvious mistakes, bugs and errors. Also, removing any code
1504 Removed files for being obsolete:
1506 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1507 inline in the file lib/silcutil/silcbuffer.h)
1509 o lib/silcutil/silcbufutil.c (the header has inline versions)
1511 Changed code to fix possible error conditions:
1513 o The buffer formatting routines now check that the destination
1514 buffer really has enough space to add the data. This applies for
1515 both buffer formatting and unformatting
1516 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1517 unformatting was changed to accomodate following rules:
1518 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1519 sent to the function while XXX_*STRING will not allocate or copy
1520 the data into the buffer. Instead it sets the pointer from the
1521 buffer into the pointer sent as argument (XXX_*STRING used to
1522 require that the pointer must be allocated already). This change
1523 makes this whole thing a bit more consistent and more optimized
1524 (note that the data returned in the unformatting with XXX_*STRING
1525 must not be freed now). The routines return now -1 on error.
1527 o Tried to find all code that use buffer_format and buffer_unformat
1528 and added return value checking to prevent formatting and
1529 especially unformatting errors and possible subsequent fatal
1532 o Changed ske->x and ske->KEY to mallocated pointers in
1533 lib/silcske/silcske.h. Fixed possible data and memory leak.
1535 o Added return value checking to all *_parse* functions. Fixed
1536 many memory leaks as well.
1538 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1539 so that buffer overflows would not happen. All code now also
1540 checks the return value as it can fail.
1542 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Added reconnection support to server if the normal server looses
1545 its connection to the router (for example if router is rebooted).
1546 The server performs normal reconnection strategy implemented
1547 to the server. Affected file silcd/server.c.
1549 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added new packet type SILC_PACKET_SET_MODE that is used to
1552 distribute the information about changed modes (for clients,
1553 channels and clients channel modes) to all routers in the
1554 network. Updated the protocol specification accordingly.
1556 Added functions into silcd/packet_send.c and
1557 silcd/packet_receive.c: silc_server_send_set_mode,
1558 silc_server_set_mode.
1560 Added new files silcmode.[ch] into lib/silccore that implements
1561 the encoding and decoding of Set Mode Payload. Added new type
1562 SilcSetModePayload. Moved the definitions of different modes
1563 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1565 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Oops, a little mistake in server's connection authentication
1568 protocol. The protocol is not ended with FAILURE but with
1569 SUCCESS if the authentication is Ok. :) Affected file is
1572 * Implemented NICK_CHANGE notify handling in server in the file
1573 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1574 the local clients on the channel. After the changing nickname
1575 in router environment snhould work and the [<unknown>] nickname
1576 should appear no more.
1578 The silc_server_replace_id function that receives the Replace ID
1579 payload now sends the NICK_CHANGE notify type also in the file
1580 silcd/packet_receive.c
1582 * Changed WHOIS and IDENTIFY command to support the maximum amount
1583 of arguments defined in protocol specs (3328 arguments). This
1584 fixed a bug that caused problems when there were more than three
1587 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Added extra parameter, command identifier, to the
1590 silc_client_send_command so that explicit command identifier
1593 Changed that ID list routines uses specific command identifier
1594 when sending WHOIS/IDENTIFY requests to the server so that they
1595 can be identified when the reply comes back.
1597 Affected files lib/silcclient/command.[ch],
1598 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1600 * Added `sender' argument to silc_server_packet_send_to_channel
1601 to indicaet the sender who originally sent the packet to us
1602 that we are now re-sending. Ignored if NULL. Affected file
1603 silcd/packet_send.[ch].
1605 * Added some server statistics support in silcd/server_internal.h
1606 SilcServerStatistics structure and around the server code. Also
1607 send some nice statistics information when client is connecting
1610 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Fixed channel ID decoding in server's JOIN command reply in
1613 silcd/command_reply.c
1615 * Fixed braodcasting of replace ID payload to not to send it if
1616 we are standalone server in silcd/packet_receive.c.
1618 * Fixed all channel message sending routines to not to send
1619 packets to clients that has router set, since they are routed
1620 separately in the same function earlier. Affects file
1621 silcd/packet_send.c and all channel packet sending functions.
1623 * In USERS reply, res_argv[i] are not allocated, the table
1624 is allocated. Thus changed that free the table, not its
1627 * In server's whois_check and identify_check if the client is
1628 locally connected do not send any WHOIS commands - they are not
1631 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Fixed some minor bugs in client when sending WHOIS command. The
1634 arguments was in wrong order.
1636 * Removed statis function add_to_channel from server in
1637 silcd/command.c that was previously used with the joining but
1640 * Tested USERS command in router environment successfully with two
1641 routers, two servers and two clients.
1643 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Reorganized the USERS command and command reply in client library
1646 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1647 When the command is given by user we register a pending command
1648 callback that will reprocess the command after the reply has been
1649 received from the server. When reprocessing the packet we then
1650 display the information. Thus, the USERS information is displayed
1651 now in the command callback instead of in the command reply
1652 callback. The processing of the command is same as previously
1653 when server has sent the command reply in the JOINing process.
1655 * Added to USERS command in silcd/command_reply.c to join the client,
1656 we didn't use to know about, to the channel after we've created
1657 a client entry for it. Also, for clienet we did know already still
1658 check whether it is on the channel or not and add it if not.
1660 * Removed silc_server_command_join_notify as the function and its
1663 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Changed the client's pending command handling to the same as the
1666 server's pending command handling. It is also now possible to
1667 execute command reply functions from other command reply
1668 function as the function callbacks for commands and command
1669 replies are one and same. The pending commands are not static
1670 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1671 in client connection context. Thus, pending commands are server
1672 connection specific as it is convenient.
1674 Changed the function silc_client_command_pending and
1675 silc_client_command_pending_del and added new function
1676 silc_client_command_pending_check. Removed the
1677 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1680 * Added cmd_ident, current command identifier, to the client
1681 connection context in lib/silcclient/client.h to keep track on
1682 command identifiers used in command sending. Client's command reply
1683 function handling now supports the mandatory command identifiers.
1685 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1686 funtions in client to fully support pending command callbacks.
1688 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1689 as one of the arguments to the application in the command reply
1692 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1693 before first releasing SILC but came back. Now it is removed again
1694 and should come back nomore. The FORWARDED flag was used only
1695 by the JOINing procedure by forwarding the command packet to router.
1696 Now, the JOINing procedure has been changed to more generic (due
1697 to various router environment issues) and FORWARDED is not needed
1698 anymore for anything. The protocol specification is yet to be
1701 Now, removed silc_server_packet_forward from server and the flag
1702 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1704 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Renamed NAMES command to USERS command. The NAMES was named that
1707 due to historical reasons. Now it is renamed. Also, rewrote
1708 parts of the USERS command. The nickname list is not sent anymore
1709 by the server. Only Client ID and mode lists are sent in the USERS
1710 command. Changed this also to the protocol specification.
1712 The client now resolves the names and stuff after it receives
1713 the USERS list from the server when joining to the channel.
1715 * WHOIS and IDENTIFY commands has been changed to support multiple
1716 Client ID's per command. One can now search for multiple users
1717 in the network by sending only one WHOIS or IDENTIFY command.
1718 Changed the code and the protocol specifications.
1720 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1721 uses silc_server_command_whois_parse to parse the request. */
1723 * If normal server, do not parse the WHOIS and IDENTIFY requests
1724 before sending it to the router. Saves some time.
1726 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Fixed JOIN command on client library. Wrong number of arguments
1729 used to crash the client.
1731 * Added silc_server_channel_has_global function to check whether
1732 channel has global users or not.
1734 * Added silc_server_channel_has_local function to check whether channel
1735 has locally connected clients on the channel.
1737 * The silc_server_remove_from_one_channel now checks whether the
1738 channel has global users or not after given client was removed from
1739 the channel. It also checks whether the channel has local clients
1740 on the channel anymore. If it does not have then the channel entry
1741 is removed as it is not needed anymore.
1743 * The silc_server_notify now checks on JOIN notify whether the joining
1744 client is one of locally connected or global. If it is global then
1745 the channel has now global users on the channel and that is marked
1746 to the channel entry. Also, it now saves the global client to
1747 global list who is joining and JOINs it to the channel. This is
1748 for normal server, that is.
1750 Changed silc_server_send_notify_on_channel,
1751 silc_server_packet_relay_to_channel and
1752 silc_server_packet_send_to_channel check if we are normal server
1753 and client has router set (ie. global client) do not send the
1754 message to that client, as it is already routed to our router.
1756 * Implemented LEAVE notify type handling in silc_server_notify
1759 * Tested LEAVE command in router environment successfully. Tested
1760 with two routers, two servers and two clients.
1764 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1766 * Implemented SIGNOFF notify type handling in silc_server_notify
1769 * silc_server_remove_id now removes the client entry from all channels
1770 it has joined and thusly sends SIGNOFF notify type.
1772 * Rewrote the NAMES list generation in server by removing two excess
1773 loops. The lists are created now inside one loop.
1775 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * silc_server_remove_channel_user checks now also global list
1778 for channel and client.
1780 * silc_server_new_channel_user checks now both local and global
1781 list for channel and client. Fixed a bug in client id decoding.
1782 Used to decode wrong buffer.
1784 * silc_server_channel_message checks now both local and global
1785 list for channel entry.
1787 * Tested channel joining (hence JOIN) in router environment
1788 successfully. Tested with two routers, two servers and two
1791 * Tested channel message sending in router environment successfully.
1793 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * Added silc_server_save_channel_key into server.[ch] to save the
1796 received channel key in Channel Key payload processing. It is
1797 also used in JOIN command reply handling.
1799 Equivalent function silc_client_save_channel_key added into
1800 client.[ch] into client library.
1802 * Changed JOIN command reply to send information whether the channel
1803 was created or not (is existing already) and the channel key
1804 payload. Changed protocol specs accordingly.
1806 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1807 the request was sent by ID and not by nickname. Crashed on
1810 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1813 now correctly save the received data.
1815 * silc_server_free_sock_user_data now notifies routers in the
1816 network about entities leaving the network.
1818 At the same time implemented functions silc_server_remove_id
1819 and silc_server_send_remove_id to receive and send REMOVE_ID
1820 packets. The packet is used to notify routers in the network
1821 about leaving entities. The ID removed will become invalid in
1824 * Added function silc_idlist_del_server into server. Removes and
1825 free's server entry from ID list.
1827 * silc_server_private_message function now checks, if we are router,
1828 that the destination ID really is valid ID, naturally.
1830 * In router when NEW_ID packet is received (for new client) the
1831 hash of the Client ID is saved in the ID Cache but the
1832 client->nickname is set to NULL, instead of putting the hash
1835 IDENTIFY command now also checks that client->nickname must be
1836 valid. If it is not if will request the data from the server who
1837 owns the client. Added new function
1838 silc_server_command_identify_check.
1840 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1841 to set the command to already allocated Command Payload.
1843 * Tested private message sending in router environment with two
1844 routers, two servers and two clients. Fixed minor bugs and now
1847 * Fixed segfault from client's NAMES command. Used to crash if
1850 * Forwarded packets must not be routed even if it is not destined
1851 to the receiver. Changed server code comply with this.
1853 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Added `require_reverse_mapping' boolean value to ServerParams
1856 structure. If TRUE (not default) the server will require that
1857 the connecting host has fully qualified domain name.
1859 If the reverse mapping is not required and hostname could not be
1860 found the IP address is used as hostname.
1862 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Implemented version string checking to both client and server.
1865 The check is incomplete currently due to the abnormal version
1866 strings used in development version of SILC.
1868 * Changed all command functions in server to use the new
1871 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Changed char *data to unsigned char *data in ID Cache system to
1874 support binary data as ID Cache data. Changed code to support
1875 binary data in lib/silccore/idcache.c.
1877 * Renamed silc_server_packet_relay_command_reply to
1878 silc_server_command_reply as it is normal packet receiving
1879 function. Rewrote the function to accept command replys for
1880 servers and not only for clients.
1882 * Mark remote router always as registered server if we are connecting
1883 to it. Otherwise, commands sent by the router to us are ignored.
1885 * All ID List find routines now returns the ID Cache Entry pointer
1886 as well if requested.
1888 * WHOIS command works now in router environment, tested with two
1889 routers, two servers and two clients.
1891 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1892 in router environment (as it is almost equivalent to WHOIS) but
1893 hasn't been tested thoroughly. Added new functions:
1895 silc_server_command_identify_parse
1896 silc_server_command_identify_send_reply
1897 silc_server_command_identify_from_client
1898 silc_server_command_identify_from_server
1900 * Disabled route cache adding because adding two different ID's with
1901 same IP replaces the old cache entry thus giving wrong route.
1902 The entry->router->connection is always the fastest route anyway
1903 so route cache may not be needed. Of course, new routes maybe
1904 established after receiving the ID when the entry->router->connection
1905 might not be anymore the most optimal.
1907 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Add route cache for received ID for fast routing.
1911 * Added silc_server_packet_route to route received packet on router
1912 that is not destined to us.
1914 * Renamed silc_server_get_route to silc_server_route_get.
1916 * Added id_string and id_string_len fields into SilcServer to
1917 include encoded ServerID for fast comparing without excess
1918 encoding of the ID's.
1920 * Cleaned up WHOIS command on server side. Added following static
1923 silc_server_command_whois_parse
1924 silc_server_command_whois_check
1925 silc_server_command_whois_send_reply
1926 silc_server_command_whois_from_client
1927 silc_server_command_whois_from_server
1929 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1930 arguments in command replies. All command functions should be
1931 updated to use this macro.
1933 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Minor typo fixes on command reply handling on server.
1937 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Added silc_server_command_add_to_channel internal routine to add
1940 the client to the channel after router has created the channel and
1941 sent command reply to the server.
1943 * Added generic silc_server_send_command to send any command from
1946 * Use static buffer with ID rendering instead of duplicating data.
1948 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Fixed a channel user mode bug when joining to a channel server gave
1951 everybody channel founder rights, oops.
1953 * We mark ourselves as the router of the incoming server connection
1954 if we are router ourselves. This way we can check in some packet
1955 sending functions whether it is locally connected server. For
1956 incoming router connections we put NULL.
1958 * For router sending packets locally means now always sending the
1959 packet cell wide; to local clients and local servers. For normal
1960 server sending packet locally means sending it to only local
1963 * Fixed the JOIN command to really work in router environment. If the
1964 channel is created it is always created by the router. Router is
1965 also responsible of making the initial joining to the channel,
1966 sending JOIN notify to the sending server and distributing
1967 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1968 does not exist server doesn't do anything else but forward the
1969 command to the router which performs everything.
1971 * Added silc_server_send_channel_key function to send the Channel Key
1974 * Added silc_server_create_channel_key to create new channel key. The
1975 channel key is now re-generated everytime someone joins or leaves
1976 a channel, as protocol dictates. Note: channel->key_len is the
1979 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1982 packet_receive.[ch] to separate packet sending and receiving
1983 routines. The server.[ch] now includes everything else including
1984 actual packet processing (writing and reading data) and other
1987 Renamed silc_server_private_message_send_internal to
1988 silc_server_send_private_message. The routine is still though
1989 used only to relay private messages as server does not send
1990 private messages itself.
1992 Renamed silc_server_new_channel to silc_server_create_new_channel
1993 and added new function sicl_server_new_channel that handles the
1994 incoming New Channel packet. Added also new sending function
1995 silc_server_send_new_channel to send New Channel Payload.
1997 * Added new function silc_server_notify to process incoming notify
1998 packet to the server/router. Server may then relay the notify
1999 to clients if needed.
2001 * Added new function silc_server_new_channel_user to process incoming
2002 New Channel User packet. Router will redistribute the packet and
2003 send JOIN notify to its local clients and locally connected servers
2004 if needed. Normal server will send JOIN notify to its local client
2005 on same channel when received this packet. Added also corresponding
2006 sending function silc_server_send_new_channel_user to sent the
2009 * Added boolean route argument to send_notif_to_channel and
2010 packet_send_to_channel functions to attempt to route the packet
2011 if it is TRUE and send only locally if it is FALSE.
2013 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * silc_server_replace_id now broadcasts the received replace ID
2016 packet if it is not broadcast packet already. The router must
2017 broadcast to inform other routers about changed ID.
2019 * Added backpointer to server's router into SilcServer context in
2020 silcd/server_internal.h.
2022 * Fixed silc_server_packet_broadcast to send correct broadcast
2025 * The channel key is now distributed to the local client as soon
2026 as it is received from the router (in router environment) so that
2027 no other packet may be sent for the channel until client has
2030 * silc_server_remove_channel_user now broadcasts the received
2031 Remove Channel User packet if it is not broadcast packet already.
2032 The router must broadcast to inform other routers about removed
2035 * Added users field into SilcPacketContext that is a reference count
2036 of the context. One can increase the reference count by calling
2037 silc_packet_context_dup which is now changed to just increase the
2038 reference count instead of duplicating the data. The reference
2039 count is decresed by calling silc_packet_context_free that will
2040 free the data after the reference count hits zero.
2042 For now on the packet context and everything allocated into it
2043 (including the raw packet from network) must be freed by calling
2044 the new silc_packet_context_free function. Added also new function
2045 silc_packet_context_alloc that must be used now to allocate the
2046 context. This also means that if a routine is asynchronous from
2047 silc_[client/server]_packet_parse_type the packet context must
2048 be duplicated by calling silc_packet_context_dup. Otherwise it
2049 gets free'd after silc_[client/server]_packet_parse_type returns.
2050 Also, one must remember that if packet is duplicated then its
2051 reference count must be decresed by calling the free function as
2052 many times as it was duplicated.
2054 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2055 from both client and server.
2057 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Made joining to a channel working in router environment.
2061 * Cleaned up JOIN command on server side and create function
2062 silc_server_command_join_channel internal routine to make the
2065 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Changed silc_command_pending list to SilcDList. Also, added
2068 `ident' field to SilcServerCommandPending structure to identify
2069 the reply and to call correct callback.
2071 Added silc_server_command_pending_check function to replace the
2072 corresnponding macro. The silc_command_pending list is not
2075 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2076 to set identifier to previously allocated Command Payload. It
2077 is used to set identifier for command when resending Command
2080 * Added silc_command_payload_encode_payload to encode Command
2081 Payload buffer from SilcCommandPayload structure.
2083 * Added silc_argument_payload_encode_payload to encode Argument
2084 payload buffer from SilcArgumentPayload structure.
2086 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Changed WHOIS command to support router connection on server side.
2089 The whois request is always sent to router unless the server is
2090 standalone server. After server has received the reply from the
2091 router will it send the reply to the client.
2093 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2094 broadcast received broadcast packet. The function is used only
2095 by router. The broadcast packet is always sent to the router's
2098 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2099 render given ID to printable string, for log files for example.
2101 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Made basic router to router connections working. At least they
2104 can now connect to each other but nothing really works the way
2105 they are supposed - yet.
2107 * Added new initiator token to RouterConnection configuration
2108 file in silcd/serverconfig.[ch]. It is used to tell whether we
2109 are the initiator to the remote router or whether we'll expect
2110 the other end to connect.
2112 * Moved registering of listener task to silc_server_init, hence
2113 the server starts listenning as soon as it is run, even if it
2114 does not have connections to other routers. Let's see how well
2117 * Changed default connection retry timeouts for more suitable in
2120 * Removed cipher and such arguments from silc_idlist_add_client
2121 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2122 Added new function silc_idlist_add_data to add the keys and stuff
2125 * Added SilcIDListData structure and added it to SilcClientEntry
2126 and SilcServerEntry as their first field in the structure. This
2127 way we can explicitly cast the ID entries to the SilcIDListData
2128 structure and get common data for the entries. In past, we had
2129 to first check what type of connection it is and then cast it to
2130 correct ID entry type. Now, we can directly cast the opaque
2131 pointer to the SilcIDListData (no matter what ID entry it actually
2132 is) and get the data needed.
2134 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2137 in some circumstances even if threre were timeout tasks, though not
2138 IO tasks, but tasks anyway. Now fixed.
2140 * Defined SilcServerConnection structure to hold connection specific
2141 stuff about directly connected servers and routers. The definition
2142 is currently in silcd/server_internal.h. I thought about having
2143 a bit more important role fro this struct but for now it is used
2144 only when connecting to other server (or router actually).
2146 * Added connecting retry support in server when connecting to
2147 router(s). The retry feature implement exponential backoff
2148 algorithm. Also, added SilcServerParams structure to hold default
2149 parameters for server. For now, it include these retry settings
2150 and are hard coded. After server is moded to be as Silc Server
2151 Library this structure will be more important.
2153 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Changed client librarys channel->clients table to SilcList and
2156 changed code accordingly.
2158 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Changed client's channel table to SilcList and changed code
2161 accordingly. Also changed SilcChannelClientEntry to include back-
2162 pointer to the channel so that client entry can use that structure
2163 as list as well and we have fast cross-reference to the channel.
2164 This change dramatically decreased the complexity of channel
2165 handling with client entry and vice versa (removed one extra
2166 loop when searching for channel entry from many functions).
2168 * Changed server->sim from table to SilcDList and changed code
2171 * NAMES command can now be used from user interface. It will show
2172 the user list on the channel, neatly.
2174 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2175 Code now saves realname of the user if it becomes available.
2177 * Renamed configure.in to configure.in.pre and made ./prepare
2178 script to automatically add correct version string to
2179 configure.in which it creates from configure.in.pre.
2181 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * NAMES command reply now shows users mode with the nickname when
2186 * Moved silc_client_ch[u]mode[_char] functions from
2187 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2188 place sucks, they are utility functions and should be in some
2191 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2193 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2196 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Added TRQ (efficient deque and list library) into lib/trq. This is
2201 a very good list library that is currently used in the SILC. Defined
2202 SilcList API over the library because I didn't like the API very
2203 much. See lib/trq/silclist.h for the API and examples of how to
2204 use the API. Fixed various places in the code to use the new
2205 SilcList API. The SilcList is meant for lists that has a structure
2206 already defined as a list. It is not suitable to add just some
2207 context to the list (in TRQ, the context is the list actually).
2209 So, I defined SilcDList that can be used for the purpose where
2210 predefined list structure does not exit. This can be used as
2211 such list. Now some context just can be added to the SilcDList.
2212 Currently this list is not used in the SILC just yet, though there
2213 are a lot places where this can replace dynamically allocated
2214 tables and I will fix these places, later, to use SilcDList.
2215 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2216 and use TRQ internally).
2218 Also fixed some annoying warning messages that the original TRQ
2219 code generated. Also minor changes to TRQ's Makefile.in.
2221 * Added support for querying by Client ID to both WHOIS and
2222 IDENTIFY commands into server, as required by the protocol.
2224 * Removed method function pointers from SilcBuffer structure. They
2225 weren't used to anything and just increased the context size for
2226 no good reason. This change also made silc_buffer_alloc and
2227 silc_buffer_free functions inline functions.
2229 * Disabled command flooding detection support until it's fixed so
2230 that it accepts commands in but does not execute them more than once
2233 * Added silc_net_localhost(), to return local hostname, into
2234 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2235 that must be initialized before calling silc_client_init.
2237 * Added new function: silc_server_send_notify_on_channels to send
2238 notify messages to all channels client has joined. It is assured
2239 that the message is sent only once per client.
2241 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2242 lib/silcutil/silcutil.[ch] as silc_format function. The new
2243 function is generic and is used by server as well, not only by
2244 the logging routines.
2246 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2247 the provided version string was not acceptable. Added new function:
2248 silc_ske_check_version into lib/silcske/silcske.h. The function
2249 must be implemented by the application (client or server) and it
2250 does not reside in the SKE library. The function checks the version
2251 string remote end sent.
2253 * Added back pointers (to opaque context and to SilcSocketConnection)
2254 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2256 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2257 duplicate packet context structure.
2259 * Changed `notify' client operation to send same arguments as client
2260 receives from server except for ID's. ID's are mapped to correct
2261 ID entry and that is returned. Also, if channel entry is not sent
2262 by server but the notify is for channel the channel entry is sent
2263 to application (otherwise application doesn't know that it is for
2264 channel (library gets it from packet's Destination ID)).
2266 * Added silc_client_remove_from_channels into client library to
2267 remove a client from all channels it has joined to. Used when
2268 received SIGNOFF notify from server. Added also new function
2269 silc_client_replace_from_channels to replace old ID entry with
2270 new ID entry on all channels. Used when received NICK_CHANGE
2273 * Fixed ID Cache list handling in silc_idlist_get_client in
2274 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2275 to get (or query) client by ID.
2277 * Updated TODO list.
2279 * Added connection authentication status message defined by the
2280 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2281 support for these into the code in client and server side.
2283 * Added generic function silc_client_send_command to send any command
2284 with variable argument list. Application should use this function
2285 to send commands if the command functions provided by the library
2286 does not suite for the application's user interface needs.
2288 * Added new `failure' client operation. Application is notified about
2289 received failure packet if client is executing a protocol. In this
2290 case the protocol's execution has failed.
2292 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2293 is required by the protocol.
2295 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2296 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2299 * Added status flag to SilcSKE object to indicate realtime status
2300 of the SKE protocol.
2302 * Application receives now exactly same command reply arguments as
2303 the library receives from server. However, if ID is received the
2304 corresponding ID entry is returned to the application (eg. Client
2305 ID is mapped to correct SilcClientEntry entry and that is returned).
2306 Changed command_reply client operation due to this change.
2308 * Changed all ID's in commands and in command replys as ID Payloads.
2309 Change affected both client and server side codes.
2311 All ID's sent in SILC network (with execption of ID's in SILC
2312 Packet header) are sent in ID Payload to support variable length
2315 * Server now notifies nick changes and notifies all clients on
2316 the channels about the new nickname (about the new Client ID,
2319 * Implemented CMODE command to change channel modes. Supports all
2320 channel modes defined by the protocol specs except ban and invite
2321 lists. (Also, private channel key mode is supported but support for
2322 setting private channel key in client is missing, thus, this mode
2323 has no effect on client side (except that server requires that the
2324 client uses private channel key and normal channel traffic does not
2327 Also, invite mode works per se, but INVITE command does not work
2328 yet correctly, so you can set channel as invite only channel but
2329 inviting clients to the channel does not work (it is yet to be
2330 thought what's the best way to do it).
2332 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2333 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2334 Implemented CUMODE command to change user's mode on the channel.
2335 Supports all modes defined by the protocol specs.
2337 * Added NAMES command reply to return users modes on the channel.
2339 * Removed unnecessary and slow ciphers from lib/silccrypt.
2341 * Set SO_KEEPALIVE option to connection sockets by default.
2343 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2345 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2346 redefined the Notify Payload into protocol specs.
2348 * Added silc_id_payload_parse_id to get ID directly from raw
2351 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2354 accept searching by Client ID as well.
2356 * Added support for LEAVE and SIGNOFF notify types in client library.
2358 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2359 to parse ID Payload from raw data.
2361 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Added flags parameter into silc_ske_assemble_security_properties
2364 function in lib/silcske/silcske.[ch].
2366 * Changed notify client operation to fit better for notify messages
2367 sent by server. The notify payload received from server is now
2368 passed to the application (after parsing it to SilcNotifyPayload).
2369 It is application's responsibility to retrieve the arguments
2370 from the payload and show the message the way it wants. The message
2371 sent by server is implementation specific.
2373 * Changed public keys to comply with the protocol specification.
2374 Old public keys are not supported anymore and are not compatible.
2376 * Removed nickname from Channel Payload as the latest draft removed
2377 it. The client must resolve the nickname from the NAMES command
2378 reply received when it joined the channel.
2380 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2382 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Fixed some errors in protocol specification drafts.
2386 * Created lib/silccore/silcnotify.c to implement Notify Payload
2387 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2388 generic payloads described by protocol specifications. The file
2389 includes implementations for ID Payload and Argument Payload.
2391 * Changed Command Payload implementation to use the new Argument
2392 Payload. Changed command_xxxx_payload to command_payload_xxxx
2393 to comply with SILC coding conventions.
2395 * Added suppport for Argument Payload handling in Notify Payload
2396 implementation as protocol requires it. Added the new support
2397 into server and client lib as well.
2399 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Added support for multiple nicknames on same channel. [n] is
2402 added locally to the nickname if there are more than one same
2403 nicknames on the channel.
2405 * Server now sends all nicknames that matched WHOIS request.
2406 Client also shows the list received from server.
2408 * Added TOPIC command to client side. User can now set and show
2409 current topic on channel.
2411 * Added MOTD command to client and server. Also, server sends the
2412 motd when client connects to the server.
2414 * Changed version strings to comply ISO 8601.
2416 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Fixed protocol error handling in client library. It should now
2419 cope even if the SKE fails for some reason.
2421 * Made new protocol specification drafts for submitting to IETF.
2423 * Implemented TOPIC command to server in silcd/command.c.
2425 * Added two new notify types into lib/silccore/silcnotify.h:
2426 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2427 notify nickname change and topic setting/change on a channel.
2429 * API change of command_reply operation in client library. The
2430 application gets now the status type received from server as well.
2432 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2436 * Cras fixed and optimized the packet handling even further and
2437 it should work now. Minor change to the prototype of function
2438 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2440 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Added new function into lib/silcutil/silcschedule.[ch]:
2443 silc_schedule_with_fd to select() a specified fd. The function
2444 returns after timeout expires or data arrives or goes. The
2445 function is used by packet routines to wait that all data is
2446 received from network.
2448 * Fixed data reading from network in lib/silccore/silcpacket.c.
2449 The code now assures that all data is read from the fd and then
2450 continues packet processing. This was a bug fix since the code
2451 used to drop some data in some circumstances.
2453 * Added new function into lib/silcclient/client.[ch]:
2454 silc_client_start_key_exchange to start key exchange after
2455 connection has been established to server. The code internally
2456 now uses this funtion but its main purpose was to provide it
2457 for applications that perform their own connecting. After
2458 application has created a connection it merely calls this
2459 function to start the key exchange between client and server.
2460 The library takes care of everything else after that.
2462 Updated also lib/silcclient/README to explain the usage of
2465 * Do not send to application information that connection has
2466 been established. Application gets notified it by connect
2469 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2471 * Applied cras's patch to add silc_schedule_one function. The
2472 function runs scheduler once and returns.
2474 * Fixed the scheduler after cras messed it up. The timeout
2475 handling works now as it's supposed to work.
2477 * Added into lib/silccore/ silcnotify.h to include notify
2478 message types support. Changed silc_server_send_notify*
2479 functions, in server.[ch], to support those new notify types.
2480 Added the support for the notify types into client library,
2481 as well. Added new notify client operation into ops.h in
2484 * Changed silc_server_packet_send_to_channel to send normal
2485 packets instead of just channel message packets. The function
2486 is now used to send the notify packets to channels. It is not
2487 used to send channel message packets anymore, as server never
2490 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2491 va_arg()s as it seems to require it nowadays. I guess, if SILC
2492 is compiled with older va_arg() the new code should work anyway.
2494 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Splitted core library. Core library (lib/silccore) includes
2497 now only SILC protocol specific core (and common) components.
2498 Created new utility library (lib/silcutil) that includes more
2499 generic purpose stuff. The stuff for util library was taken
2500 from the old core library. This was minor and easy split.
2502 * Created SILC Client Library (lib/silcclient) that includes
2503 implementation of the SILC client without user interface. This
2504 was major move from silc/ directory. The code has been changed
2505 so that it is transparent towards the user interface. The
2506 silc/ directory includes now the same user interface as before
2507 and it uses the new client library. Read lib/silcclient/README.
2508 Basicly, the client library performs everything else related
2509 to SILC except user interface handling. Also, configuration
2510 files are considered to be part of user interface and library
2511 does not handle them.
2513 This change also changed a lot of structures, function naming etc.
2514 Most important change was that SilcClientWindow object was
2515 renamed to SilcClientConnection in the client library. Created
2516 also new file lib/silcclient/ops.h. Also added new files
2517 silc/local_command.[ch] and silc/client_ops.[ch].
2519 All these changes were made to make it easier for user interface
2520 designers to create what ever user interface for the SILC client
2523 It is also expected that the server will be moved to lib
2524 directory as well and SILC Server Library will be created;
2525 sometimes in the future.
2527 * Removed Local commands from lib/silccore/silccommand.h as
2528 they are application specific and new client library does not
2529 handle any of those anymore.
2531 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2532 old client implementation in silc/.
2534 * Added support for callback functions in SILC_LOG_* macros.
2535 Application can now set its own callbacks that will be called
2536 instead of using the default functions that will always print
2537 the debug messages to stderr (or stdout). Also, debugging can
2538 now be disabled by setting silc_debug to FALSE and re-enabled by
2539 setting it to TRUE. Note, that logging will still work even
2540 if debugging is disabled.
2542 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2543 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2544 silc_log_reset_debug_callbacks.
2546 * To enable debugging in silc client one must give now -d
2547 option on command line.
2549 * Changed silc_schedule_init to automatically allocate task queues
2550 if they are not allocated before calling it.
2552 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * Added GMP 3.1 into math library.
2556 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2559 a channel in SILC network. The packet is used by servers and
2560 routers to notify other routers that user has left a channel.
2561 This little feature was missing until now. Added the feature
2562 to protocol specification as well.
2564 Added functions: silc_server_send_remove_channel_user and
2565 silc_server_remove_channel_user into server.[ch].
2567 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2568 lib/silccore/silcpacket.h. However, they are not implemented
2571 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Fixed joining to a channel and sending channel messages
2574 between server and router. The channel message sending should
2575 now work inside a cell.
2577 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Fixed the private message sending between server and router.
2580 The private message sending should now work inside a cell.
2582 * Added silc_server_replace_id into server.[ch] to replace
2583 existing ID in the SILC network.
2585 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2586 and silc_idlist_replace_server_id into idlist.[ch] in server.
2588 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Fixed the server to server connections. Server can again now
2591 connect to router. Router to router connections probably does
2594 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Added dynamic protocol registering support. Now protocols can
2597 registered and unregistered on the fly. Patch by cras.
2599 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added lib/contrib directory to hold routines that some platforms
2602 don't have but are needed by SILC.
2604 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2605 into lin/contrib to provide getopt() and getopt_long() for
2606 those who don't have it.
2608 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Added AWAY command to client. When away message is set and
2611 client receives a private message packet the client automatically
2612 replies to the sender with the away message.
2614 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2615 bug seemed to be the cause of recent problems when compiling
2618 * Added version detection support to SKE protocol specification
2619 and added the new changes to the SKE implementation as well.
2620 There were other minor changes in the SKE protocol as well.
2622 Many changes in lib/silcske/silcske.[ch] and in
2623 lib/silcske/payload.[ch].
2625 * Added ^U functionality, clear input line. Patch from cras.
2627 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Mainly small bugfixes on core library. Fixed some debugging
2630 logging and buffer overflow in silclog.c.
2632 * Updated config.sub and config.guess on the distribution tree.
2634 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added command lagging support in server. Client may execute
2637 commands now only once in two seconds.
2639 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Optimized packet reception. MAC computation and checking is now
2642 also more optimized. A lot previously duplicated code is now
2643 used as generic by both client and server.
2645 * Fixed key pair generation in clientutil.c
2647 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Added into lib/silccore/silcbufutil.[ch] new function;
2650 silc_buffer_realloc.
2652 * Moved generic packet sending/encryption functions to
2653 lib/silccore/silcpacket.[ch] from client and server. Some
2654 rewriting of the functions.
2656 * Moved all generic packet reception/decryption functions to
2657 lib/silccore/silcpacket.[ch] from client and server. The
2658 packet processing is now much cleaner in both client and server.
2659 These were major changes in both client and server.
2661 * Created many common functions in server to do packet sending.
2662 Previously code were duplicated a lot, this has been removed
2665 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Rewrote major parts of the ID cache system. Don't know
2668 whether it is better now or not but at least the API is more
2671 * Major rewrite on ID cache stuff on client because of the ID
2672 cache API changes. Added idlist.c to client.
2674 * Also major rewrite on ID cache stuff on server as well.
2675 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2676 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2677 in hand, instead they are all put into the ID cache system now.
2678 All server_idlist_* routines uses ID cache now instead of
2679 traversing its own lists (those lists does not exist anymore).
2680 SilcIDList though still exists. Also, SilcXXXEntry's are
2683 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Finally made the SKE implementation compliant to the protocol
2686 specification. All mp integers are now binary encoded as
2687 opposed being HEX encoded.
2689 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2692 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2693 functions: silc_[encode/decode]_pem. Also added function
2694 silc_encode_pem_file to PEM encode with newlines ('\n') for
2697 * SILC public keys are now encoded either PEM or binary. Same
2698 option is for private keys as well. By default private keys
2699 are binary encoded and public keys PEM encoded. Silly HEX
2700 encoding were removed.
2702 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2703 function to create fingerprints.
2705 * Fixed a bug in SHA1; does not change the original data anymore.
2707 * Partly implemented INFO command on client and server side.
2708 Fixed CLEAR command. Changes to SERVER command; show current
2709 server(s) when giving command without arguments. Added
2710 VERSION command to client.
2712 * Added check to server that unregistered connections cannot
2713 execute commands (unless it is specificly allowed).
2715 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Fixed screen refresh.
2719 * Fixed channel joining bug from client. On some circumstances
2720 client tried to join to a channel it had already joined.
2722 * Added public key verification process into client's protocol.c.
2723 The client now verifies the public key from user and saves
2724 it into ~./silc/serverkeys/ directory.
2726 Added into: clientutil.[ch]: silc_client_verify_server_key.
2728 * Changed SKE protocol's silc_ske_initiator_finish function
2729 to accept callback function that verifies the received public
2730 key. Removed old silc_ske_verify_public_key function.
2732 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2735 silc_pkcs_private_key[_data]_set.
2737 * Made the password and public authentication more cleaner in
2738 server's protocol.c.
2740 * Removed historic and obsolete protocol `channel_auth' from
2741 both client and server.
2743 * Removed wrong way of sending command status messages from
2744 server to client in server's command.c. The old way violated
2745 protocol specification.
2747 Changes to silccore/silccommand.[ch]: removed
2748 silc_command_encode_status_payload -> not needed anymore,
2749 changed silc_command_encode_payload_va to accept extra
2750 argument on variable argument list. The argument type must
2751 now be provided to the function. Also, added new function:
2752 silc_command_encode_reply_payload_va which is same as
2753 normal command_encode_payload_va except command status type
2754 is provided as extra argument.
2756 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Added ~./silc directory handling. The directory includes the
2759 public and private keys for the client.
2761 Added silc_client_check_silc_dir, silc_client_create_identifier
2762 and silc_client_load_keys.
2764 * Implemented SILC protocol compliant public key. Added public
2765 and private key saving to and loading from files.
2767 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2768 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2769 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2770 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2771 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2773 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2774 silc_pkcs_load_[public/private]_key.
2776 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Added silc_server_get_route (route.[ch]) to get connection
2779 data for the fastest route for given ID.
2781 * Implemented INVITE command on client and server. The command
2782 were re-defined in the SILC Protocol Specification and the
2783 implementation now complies with the specification.
2785 * Implemented PING command on client and server.
2787 * Implemented NAMES command on client and server. The server side
2788 supports currently only normal server not router server yet.
2789 Some changes to NAMES definition in SILC protocol specification.
2791 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Implemented LEAVE command on client and server.
2795 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2796 again. This change was made to the protocol as well. Server
2797 should not violate the protocol specification anymore.
2799 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
