3 * Fixed the WHOIS and IDENTIFY send reply function to really
4 check whether to send list or just one entry. Affected file
7 * Cleaned up the LEAVE command's channel key distribution. The
8 affected file silcd/command.c.
10 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
11 can enforce the channel mode as well. In that case the ID
12 includes the ID of the server. The code now enforces the
13 mode change if the router have different mode than the server.
15 * The notify client operation with CMODE_CHANGE notify can now
16 return NULL client_entry pointer if the CMODE was not changed
17 by client. Application must check for this.
19 * Added <Server ID> argument to INFO command to support server
20 info fetching by Server ID.
22 * Added silc_server_announce_get_channel_users to get assembled
23 packets of channel users of the specified channel. Affected
24 file silcd/server.[ch].
26 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
27 was freed underneath the ID Cache.
29 * Re-announce clients when the server received CHANNEL_CHANGE
30 notify from the router. Affected file silcd/packet_send.c.
32 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
35 crashed since it did not handle the fact that there is no cipher
36 called "3" and didn't check the error condition. Now fixed.
38 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
39 flag. It can be used to send message requests.
41 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
43 * Implemented the RESTART command in the client.
45 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
46 notice type messages. Added notice printing to the user
49 * The channel keys are not re-generated if the channel's mode
50 is PRIVKEY, ie private key on the channel exists. Affected
51 files silcd/server.c and silcd/command.c.
53 * Fixed a little bug in channel message delivery when channel
54 private keys are set in the server. Affected file is
57 * Changed the setting on channel->on_channel = TRUE from the
58 silc_client_save_channel_key to the JOIN command reply. The
59 key payload is not received if the private channel key is set.
60 Affected file lib/silcclient/command_reply.c and the
61 lib/silcclient/client_channel.c.
63 * When the CMODE_CHANGE notify is sent and the channel private
64 key mode is removed the channel key must be re-generated in
65 other cells as well. Added this support for the router in the
66 silcd/packet_receive.c.
68 * Added new local command NOTICE to send notice message on
69 channel. Affected file silc/local_command.[ch].
71 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Added new local command ME to the client. It is used to send
74 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
75 some action. Affected file silc/local_command.[ch].
77 * Changed channel_message and private_message client operations
78 to deliver the message flags to the application. Added also
79 the `flags' arguments to the silc_client_send_channel_message
80 and silc_client_send_private_message functions. Affected file
83 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Redefined the Private Message Payload to support private message
86 keys and to support the new private message flags. Updated
87 the protocol specs. Flags makes it possible to have for example
90 * Added new type SilcPrivateMessagePayload and defined an API
91 for it in the lib/silcclient/silcprivate.[ch].
93 * Tested private message private keys successfully. Tested the
94 private message key set, unset and list commands with the new
97 * Redefined the Channel Message Payload to include the channel
98 message flags (equal with private message flags) to support
99 for example CTCP style messages.
101 * Defined some of the message (for channel and private message)
102 flags. Updated the protocol specs and added the flags to the
103 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
105 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
107 * Added SilcKeyAgreementStatus type to the key agreement routines
108 to indicate the current status and error if one occured.
109 The status types are defined in the lib/silcclient/silcapi.h.
111 * Added new local command KEY that is used to set and unset private
112 keys for channels, set and unset private keys for private messages
113 with remote clients and to send key agreement requests and
114 negotiate the key agreement protocol with remote client. The
115 key agreement is supported only to negotiate private message keys,
116 it currently cannot be used to negotiate private keys for channels,
117 as it is not convenient for that purpose.
119 * Fixed a minor pending callback setting bug in the function
120 silc_client_get_client_by_id_resolve, now the function works.
121 Affected file lib/silcclient/idlist.c.
123 * Added function silc_net_get_local_port to get local bound
124 port by socket. Added to lib/silcutil/silcnet.[ch].
126 * Added `sockets' and `sockets_count' fields to the SilcClient
127 object. They hold the sockets of the listenning sockets in
128 the client. Listenning sockets may be for example the key
129 agreement server. Affected file lib/silcclient/client.[ch].
130 Added functions the silc_client_add_socket and the
131 silc_client_del_socket. They are exported to the application
134 * Added ~./silc/clientkeys to support other client's public keys.
136 * Renamed verify_server_key client operation to verify_public_key
137 and added one argument to indicate the type of the connection
138 (server, client etc.).
140 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * Added silc_server_connection_auth_request to handle the
143 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
144 silcd/packet_receive.[ch].
146 * Added silc_server_send_connection_auth_request into the
147 silcd/packet_send.c to send the connection auth request packet.
149 * Cleaned up the silcd/protocol.c a bit and fixed some memory
152 * Fixed the public key authentication in responder side in the
153 server. The `auth_data' pointer includes the SilcPublicKey
154 not the path to the public key. Affected file silcd/protocol.c.
156 * Implemented the public key authentication in the initiator side
157 in the server. Affected file silcd/protocol.c.
159 * Removed the [RedirectClient] config section from the server
160 configuration. Is not needed and I don't want to implement it.
162 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Cleaned up the CMODE command in the server. It now works
165 correctly and supports all the modes defined in the protocol.
166 Affected file is silcd/command.c.
168 * Added `hmac_name' field to the SilcChannelEntry in the server
169 to hold the default HMAC of the channel. It can be set when
170 creating the channel (with JOIN command). Affected files
173 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
174 type to indicate the change of the current cipher and hmac
175 on the channel. Client can safely ignore the <cipher> argument
176 (if it chooses to do so) since the CHANNEL_KEY packet will
177 force the channel key change anyway. The <hmac> argument is
178 important since the client is responsible of setting the new
179 HMAC and the hmac key into use.
181 * Fixed the CMODE command in the client library as well.
183 * Tested CMODE command in router environment successfully.
185 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Show the version of the remote client (or server) when connecting
188 to the server. It is logged to the log file. Affected file
191 * Fixed the KILLED notify handling in the client library. The
192 client must be removed from all channels when receiving the
195 Also, do not remove the client entry when giving the KILL
196 command but when the KILLED notify is received.
198 * Removed silc_idlist_find_client_by_nickname from the server.
199 Not needed anymore. Affected files silcd/idlist.[ch].
201 * Implemented the CHANNEL_CHANGE notify type handling to the
202 server. Affected file silcd/server.c.
206 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

221 client entry by ID from all ID lists and then resolve it
222 (using WHOIS) if it cannot be found. Affected file is
225 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Implemented the BAN command to the client library.
229 * The JOIN command in the server now checks the invite list
232 * Changed the silc_command_reply_payload_encode_va and the
233 silc_command_payload_encode_va to support that if argument is
234 NULL it ignores and checks the next argument. Affected file
235 lib/silccore/silccommand.c.
237 * Added silc_server_send_notify_ban to send the BAN notify
238 type between routers.
240 * Chaned the silc_notify_payload_encode to support that if
241 argument is NULL it ignores and checks the next argument.
242 Affected file lib/silccore/silcnotify.c.
244 * Tested ban lists in router environment successfully.
246 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Implemented BAN command to the server, in silcd/command.[ch].
250 * Removed the BAN and INVITE_LIST modes from the CMODE command
253 * Added function silc_string_match to regex match two strings.
254 Affected files lib/silcutil/silcutil.[ch].
256 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Redefined parts of the SilcChannelEntry in the server to support
259 the new ban and invite lists.
261 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Redefined the INVITE command. The same command can be used to
264 invite individuals to the channel but also to manage the invite
265 list of the channel (to add to and remove from the invite list).
266 Updated the protocol specs.
268 * Added new command SILC_COMMAND_BAN that can be used to manage
269 the ban list of the channel. Updated the protocol specs.
271 * Removed the channel modes: the SILC_CMODE_BAN and the
272 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
273 in the CMODE command. The equivalent features are now available
274 using INVITE and BAN commands. Updated the protocol specs.
276 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
277 in the network about change in the current ban list. The notify
278 type is not used by the client.
280 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
281 support the invite lists.
283 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Added new function silc_string_regexify that converts string
286 including wildcard characters into regex string that can
287 be used by the GNU regex library. Added into the file
288 lib/silcutil/silcutil.[ch].
290 Added silc_string_regex_combine to combine to regex strings
291 into one so that they can be used as one regex string by
292 the GNU regex library. Added into the file
293 lib/silcutil/silcutil.[ch].
295 Added silc_string_regex_match to match two strings. It returns
296 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
298 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Imported GNU regex to the soruce tree into lib/contrib.
301 Fixed some compiler warning from the regex.c.
303 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Fixed MOTD command in the server to work in router environment.
307 * Fixed the MOTD command in the client library to support
308 the server argument in the command.
310 * Added `nickname_len' argument to the silc_idlist_add_client
311 in the server, as the `nickname' argument may be binary data
314 * Added silc_idlist_get_channels to return all channels from
317 * Implemented LIST command to the server. Affected file is
320 * Implemented the LIST command to the client library and on the
323 * Added [<user count>] argument to the LIST command reply.
324 With private channels the user count is not shown.
326 * Updated TODO and README.
328 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * The client entry's data.registered must be TRUE even with
331 global client entry on global client list. The data.registered
332 is used to check whether the client is anymore in the network,
333 for example with WHOWAS command so it must be valid.
335 * Fixed the WHOWAS command in the server. It now actually works
336 in router environment. Added function into silcd/command_reply.c
337 silc_server_command_reply_whowas_save.
339 * Added silc_idlist_purge function to the silcd/idlist.c
340 to periodically purge the ID Cache.
342 * Fixed INFO command in the server. It works now in router
343 environment. Added <server name> argument to the INFO command
344 reply. Updated the protocol specs.
346 * Fixed minor bug in silc_idcache_purge to not purge if the
347 expire value is zero.
349 * Fixed various bugs in WHOIS and IDENTIFY command handling as
350 they were buggy because of the WHOWAS information.
352 * Fixed local command MSG to handle the async resolving of
353 the remote client properly. It used to fail the first MSG.
354 Affected file silc/local_command.c.
356 * Added `data_len' field to SilcIDCache context.
358 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Update TODO. Todo in commands in the server.
362 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
365 used by routers as broadcast packet to inform other routers
366 about the changed user mode.
368 Implemented the notify handling in the server. Affected file is
369 silcd/packet_receive.c. Added the function
370 silc_server_send_notify_umode to the silcd/packet_send.[ch].
372 * Added new generic Channel Payload and deprecated the New Channel
373 Payload. The New Channel Payload is now the generic Channel
376 * Added new argument `mode' to the silc_server_send_new_channel
377 as it is required in the Channel Payload now.
379 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
380 and created a new and real SilChannelPayload to represent the
381 new generic Channel Payload. Implemented the encode/decode
382 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
384 * Added silc_server_get_client_channel_list to return the list
385 of channels the client has joined for WHOIS command reply.
386 Affected file silcd/server.[ch].
388 * Implemented the channel list sending in the WHOIS command reply
389 in server and in the client.
391 Implemented the channel list displaying on the user interface
392 as well. Affected file silc/client_ops.c.
394 * Added silc_channel_payload_parse_list to parse list of Channel
395 Payloads. It returns SilcDList list of SilcChannelPayloads.
396 Client for example can use this function to parse the list of
397 channels it receives in the WHOIS command reply. The caller
398 must free the list by calling silc_channel_payload_list_free.
399 Affected files lib/silccore/silcchannel.[ch].
401 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Added one new argument <user mode> to the WHOIS command reply
404 to return the mode of the user in SILC. Updated the protocol
407 Implemented it to the server and client.
409 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Fixed the mode printing on the user interface on joining.
412 Affected file silc/client_ops.c.
414 * Implemented the UMODE command and user modes in general to the
415 client library and to the user interface.
417 * Implemented the UMODE command to the server.
419 * The server now sends UNKNOWN_COMMAND error status if client sends
420 unknown command. Affected file silcd/command.c.
422 * All server commands now handle the command identifier the right
423 way when sending the command reply to the client. The client can
424 use to identify the command replies with the identifier.
426 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Added silc_server_get_client_route to resolve the route to
429 the client indicated by the client ID. Affected file is
432 * Added silc_server_relay_packet as general function to relay
433 packet to arbitrary destination. This deprecates functions
434 like _send_private_message_key, _relay_notify etc. Affected
435 file is silcd/packet_send.[ch].
437 Removed silc_server_send_key_agreement,
438 silc_server_send_private_message_key and
439 silc_server_packet_relay_notify functions from the file
440 silcd/packet_send.[ch].
444 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
445 server. Affected file silcd/packet_receive.[ch].
447 * Implemented the KILL command to the client. Implemented the
448 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
449 Affected files lib/silcclient/command[_reply].c and
450 lib/silcclient/client_notify.c. Implemented the KILL notify
451 printing in the user inteface.
453 * Fixed a lot silc_parse_nick memory leaks from the client
454 library in the file lib/silcclient/command.c.
456 * Changed the silc_server_send_notify_on_channels's `sender'
457 argument from SilcSocketConnection to SilcClientEntry to
458 check the sender as entry and not as connection object and not
459 to send to the client provided as argument. The affected file
460 is silcd/packet_send.[ch].
462 * The notify packets that are destined directly to the client used
463 to not to be processed by the server. Now changed that and the
464 server processes all notify packets. After relaying the packet
465 to the client the notify packet is processed in the server.
467 * The silc_server_free_client_data now checks whether there is
468 pending outgoing traffic for the client and purges the data to
469 the network before removing the client entry.
471 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
474 an client is killed from the SILC Network. Updated the protocol
477 Added new function silc_server_send_notify_killed to the
478 silcd/packet_send.[ch].
480 * Added function silc_server_packet_relay_notify to relay notify
481 packets that are destined directly to a client. In this case
482 the server does not process the notify packets but merely relays
483 it to the client. Affected file silcd/packet_send.[ch].
485 Added also silc_server_packet_process_relay_notify to check
486 whereto relay the notify. Affected file is
487 silcd/packet_receive.[ch].
489 * Implemented the KILL command to the server.
493 * Added the backup schema desgined last fall to the protocol
494 specs for everyone to see. The specification is in the
495 *-spec-xx.txt draft and the packet type definitions for the
496 backup routers is in *-pp-xx.txt draft. Thusly, added also
497 new packet type SILC_PACKET_CELL_ROUTERS.
499 * A big security problem in the implementation discovered. The
500 signoff of an client did not cause new channel key generation
501 which it of course should've done. The channel keys must be
502 always re-generated when client leaves (or signoffs) the channel.
503 The silc_server_remove_from_channels funtion now handles
504 the channel key re-generation.
506 * Added `sender' argument to the silc_server_send_notify_on_channels
507 to not to send the client provided as argument. Affected file
508 silcd/packet_send.[ch].
510 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Implemented OPER and SILCOPER commands into the server and
515 * Added silc_auth_verify and silc_auth_verify_data to verify
516 the authentication directly from the authentication payload.
517 It supports verifying both passphrase and public key based
518 authentication. Affected file lib/silccore/silcauth.[ch].
520 * Added `hash' field to the SilcIDListData structure. It is the
521 hash negotiated in the SKE protocol. Affected file is
524 * Slight redesigning of the SilcAuthPayload handling routines.
525 Do not send SilcPKCS but SilcPublicKey as argument.
527 * Implemented the public key authentication support to the
528 serverconfig. The public key is loaded from the provided path
529 and saved as authentication data to void * pointer. Thus,
530 changed the unsigned char *auth_data to void *auth_data;
532 * Fixed SHUTDOWN command to send the reply before the server
533 is shutdown. :) Affected file silcd/command.c.
535 * Fixed fatal bug in CONNECT command. The hostname was invalid
536 memory and server crashed. Affected file silcd/command.c.
538 * Fixed fatal bug in CLOSE command. The server_entry became
539 invalid but was referenced later in the command. Affected file
542 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Fixed fatal bug in failure packet handling. Server ignored
545 the failure and thus crashed when it came.
549 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
552 that the command may be executed only once in (about) 2 seconds.
553 The old SILC_CF_LAG flag is same but allows command bursts up
554 to five before limiting.
556 Added the support for CF_LAG and CF_LAG_STRICT flags to the
557 server code. Various commands now includes the CF_LAG_STRICT
558 flag to disallow any kind of miss-use of the command.
560 * Fixed the silc_buffer_unformat to not to allocate any data
561 if the length of the data is zero. It used to allocate the
562 length + 1. Affected file lib/silcutil/silcbuffmt.c.
564 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Changed the format of AdminConnection configuration section
567 in the server. Added username of the admin to the format.
568 Affected files silcd/serverconfig.[ch].
570 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
571 to return admin configuration data by host, username and/or
574 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Implemented WHOWAS command to the server. Added the functions:
578 silc_server_command_whowas_parse,
579 silc_server_command_whowas_send_reply,
580 silc_server_command_whowas_from_client and
581 silc_server_command_whowas_from_server
583 * Added <Client ID> argument to the WHOWAS command reply. Updated
584 the protocol specs accordingly.
586 * Implemented WHOWAS command and command_reply to the client
589 Implemented the WHOWAS printing on the user interface.
591 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
593 * Added new argument to the WHOWAS command reply, the real name.
594 It is an optional argument. Updated the protocol specs.
596 * Added SilcIDCacheDestructor callback that is registered when
597 the SilcIDCache is allocated. The callback is called when
598 an cache entry in the ID Cache expires, or is purged from the
599 cache. Added into lib/silccore/idcache.[ch].
601 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
602 to destruct the client entries when the cache entry expires.
603 Other ID Cache's in server and in the client library ignores
606 * If the ID Cache entry's `expire' field is zero then the entry
607 never expires. Added boolean `expire' argument to the
608 silc_idcache_add function in the lib/silccore/idcache.[ch].
609 If it is TRUE the default expiry value is used.
611 * Added silc_server_free_client_data_timeout that is registered
612 when client disconnects. By default for 5 minutes we preserve
613 the client entry for history - for WHOWAS command.
615 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Added support to the server to enforce that commands are not
618 executed more than once in 2 seconds. If server receives
619 commands from client more frequently, timeout is registered
620 to process the commands. Affected file silcd/command.c.
621 Added new function silc_server_command_process_timeout.
623 * Changed NICK_NOTIFY handling in client library to check that
624 if the client's nickname was changed, so there is no need to
625 resolve anything from the server.
627 * Removed error printing from the WHOIS and IDENTIFY commands.
628 If error occurs then it is ignored silently in the client library.
629 The application, however, may map the received error to
630 human readable error string. The application currently maps
631 the NO_SUCH_NICKNAME error to string.
633 * Made the command status message public to the application. Moved
634 them from lib/silcclient/command_reply.c to
635 lib/silcclient/command_reply.h. The application can map the
636 received command status to the string with the
637 silc_client_command_status_message function.
639 * Added check to the server to check that client's ID is same
640 as the Source ID in the packet the client sent. They must
643 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Added dist-bzip hook to the Makefile.am to make bzip2
646 compressed distributions.
648 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Server now enforces the maximum length for the nickname and
651 the channel as protocol specification dictates. 128 bytes for
652 nickname and 256 bytes for channel name.
654 * Moved the WHOIS printing to the application. The client libary
655 does not print out the WHOIS information anymore, the application
656 must do it. Renamed silc_client_command_reply_whois_print to
657 the silc_client_command_reply_whois_save.
659 The client's idle time is also sent to the application now, and
660 the idle is shown on screen.
662 * Added silc_client_command_reply_identify_save to save the
663 received IDENTIFY entries.
665 * Do not check for channel private keys in message sending and
666 reception if the channel does not have the PRIVKEY mode set.
667 Affected file lib/silclient/client_channel.c.
669 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
672 just surfaced after chaning the JOIN procedure.
674 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Added silc_client_get_clients_by_list to get client entries
677 from Client ID list, that is returned for example by JOIN
678 and USERS command replies. The application should use this
679 function for example when JOIN command reply is received to
680 resolve the clients already on the channel (library does not
681 do that anymore as USERS command reply is not used in the JOIN
682 procedure anymore). Affected files lib/silcclient/silcapi.h and
683 lib/silcclient/idlist.c.
685 * JOIN command reply and USERS command reply returns now SilcBuffer
686 pointers instead of unsigned char pointers when returning
687 the client list and mode list.
689 * Added <Client ID> argument to the JOIN command reply, mainly
690 for the server to identify for which client the command was
691 originally sent. Updated protocol specs accordingly.
693 * Added SilcDlist private_key pointer to the SilcChannelEntry
694 in the client to support the channel private keys. Affected
695 file is lib/silcclient/idlist.h.
697 * Added SilcChannelPrivateKey argument to the function
698 silc_client_send_channel_message so that application can choose
699 to use specific private ke if it wants to. If it is not provided,
700 the normal channel key is used, unless private keys are set.
701 In this case the first (key that was added first) is used
702 as the encryption key.
704 * Implemented the support for channel private key handling.
705 Implemented the following functions:
707 silc_client_add_channel_private_key,
708 silc_client_del_channel_private_keys,
709 silc_client_del_channel_private_key,
710 silc_client_list_channel_private_keys and
711 silc_client_free_channel_private_keys
713 Affected file lib/silcclient/client_channel.c.
715 * Added the support for the private keys in the channel message
716 sending and encryption and in the message reception and
717 decryption. Affected funtions are
718 silc_client_send_channel_message and silc_client_channel_message.
720 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Added SKE's key verify callback to the client library's
723 KE protocol context. Affected files lib/silcclient/protocol.[ch].
725 * Removed the statement that server (or router) must send USERS
726 command reply when joining to the channel so that the client
727 knows who are on the channel. Instead, the client list and
728 client's mode list is now sent in the JOIN command reply to the
729 client who joined channel. This is better solution.
731 * Added function silc_server_get_users_on_channel and function
732 silc_server_save_users_on_channel to the silcd/server.[ch].
734 * Removed function silc_server_command_send_users from the
737 * Do not show topic on the client library anymore. The topic is
738 sent in the command reply notify to the application and the
739 application must show the topic now.
741 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Added client searching by nickname hash into the IDENTIFY and
744 WHOIS commands in the server as they were clearly missing from
745 them. Affected file is silcd/command.c.
747 * Fixed a bug in private message receiving in the client library.
748 The remote ID was freed and it wasn't supposed, now it is
751 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Minor fix to the channel payload; allocate the data area, as it
754 needs to be of specific length.
756 * If the key agreement port is zero then the operating
757 system will define the bound port. Affected files are
758 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
760 * Added new function silc_channel_payload_decrypt into the file
761 lib/silccore/silcchannel.[ch].
763 * Moved the channel message etc, check from silc_packet_decrypt
764 to applications. The library calls now a generic
765 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
766 when the packet is either normal or special. This was done to
767 allow more wide range of checking that was not allowed when
768 the code was in library. Now applications can do virtually any
769 checks to the packet and return to the library the decision how
770 the packet should be processed. Affected files are
771 lib/silccore/silcpacket.[ch].
773 Added silc_server_packet_decrypt_check to the server and
774 silc_client_packet_decrypt_check to the client library.
776 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
777 to send with specified source and destination information.
779 * Channel message delivery between routers was broken after the
780 channel key distribution was fixed earlier. The channel key
781 was used be to distributed to other routers as well which is not
782 allowed by the protocol. Now this is fixed and channel keys
783 really are cell specific and the channel message delivery between
784 routers comply with the protocol specification.
786 * Fixed various commands in server to check also the global list
787 for the channel entry and not just the local list. The affected
788 file silcd/command.c.
790 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Added assert()s to buffer formatting and unformatting routines
793 to assert (if --enable-debug) when error occurs. Affected
794 file: lib/silcutil/silcbuffmt.c.
796 * Changed to auto-reconnect to check whether the remote host is
797 router and register the re-connect timeout if it is. It used
798 to check that whether we are normal server, but router must do
799 auto-reconnect with another router as well. Affected file
802 * Removed the [<key len>] option from CMODE command as the cipher
803 name decides the key length, nowadays. See the defined ciphers
804 from the protocol specification.
806 * Added [<hmac>] option to the CMODE command to define the HMAC
807 for the channel. Added SILC_CMODE_HMAC channel mode.
809 * Added [<hmac>] option for the JOIN command so that user can
810 select which HMAC is used to compute the MACs of the channel
813 * Added Hmac field to the Channel Message Payload. The integrity
814 of plaintext channel messages are now protected by computing
815 MAC of the message and attaching the MAC to the payload. The
816 MAC is encrypted. Now, it is clear that this causes some
817 overhead to the size of the packet but rationale for this is that
818 now the receiver can verify whether the channel message decrypted
819 correctly and also when private keys are set for the channel the
820 receiver can decrypt the packet with several keys and check from
821 the MAC which key decrypted the message correctly.
823 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
824 lib/silccrypt/silccipher.[ch].
826 * Added silc_hash_len to return the digest length into the
827 lib/silcrypt/silchash.[ch].
829 * Rewrote parts of Silc Channel Payload interface in the
830 lib/silccore/silcchannel.[ch]. The encode function now also
831 encrypts the packet and parse function decrypts it.
833 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Fixed a minor formatting bug in the SKE's key material processing.
836 It actually might have processed the keys wrong way resulting
839 * Redefined the mandatory HMAC algorithms and added new algorithms.
840 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
841 and hmac-md5 truncated to 96 bits. The mandatory is now
842 hmac-sha1-96. Rest are optional (including the one that used
843 to be mandatory). Rationale for this is that the truncated HMAC
844 length is sufficient from security point of view and can actually
845 make the attack against the HMAC harder. Also, the truncated
846 HMAC causes less overhead to the packets. See the RFC2104 for
849 * Added new [hmac] configuration section. The SKE used to use
850 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
851 is of course wrong. The official names that must be proposed in
852 the SKE are the ones defined in the protocol specification
853 (hmac-sha1-96 for example). The user can configure any hmac
854 using any hash function configured in the [hash] section. At
855 least, the mandatory must be configured.
857 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
859 * Added HMAC list to the SKE proposal list. It has now both
860 hash algorithm list and HMAC list. This makes the protocol
861 incompatible with previous versions. The SKE now seems to work
862 the way it is supposed to work, for the first time actually.
864 * Defined plain Hash algorithms to the protocol specification.
867 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Implemented support for key agreement packets into the server.
870 Added functions silc_server_key_agreement and
871 silc_server_send_key_agreement. Other than these functions,
872 server has nothing to do with this packet.
874 * Added support for private message key packets into the server.
875 Added functions silc_server_private_message_key and
876 silc_server_send_private_message_key.
880 * Changed the silc_[client|server]_protocol_ke_set_keys to be
881 called in the protocol's final callback instead in the END
882 protocol state. This makes a little more sense and in the same
883 time in client we can use the same protocol routines for normal
884 key exchange and to key agreement packet handling as well.
886 * Added to both client's and server's KE protocol context the
887 SilcSKEKeyMaterial pointer to save the key material. We will
888 bring the key material to the protocol's final callback by doing
889 this. The final callback must free the key material.
891 * Added SKE's packet_send callback into client's KE protocol
892 context so that the caller can choose what packet sending function
893 is used. This way we can use different packet sending when
894 doing normal SKE when doing key agreement packet handling (in
895 the key agreement packet handling we do not want to encrypt
898 * Implemented the responder side of the key agreement routines
899 in the client. The client can now bind to specified port and
900 accept incoming key negotiation. The key material is passed
901 to the application after the protocol is over.
903 * Implemented the processing of incoming Key Agreement packet
904 in the client. Added function silc_client_key_agreement to
907 * Implemented the intiator side of the key agreement routines
908 in the client. The client can now initiate key agreement with
909 another remote client. The key material is passed to the
910 application after the protocol is over.
912 * Created client_keyagr.c to include all the key agreement
915 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
916 SILC_TASK_CALLBACK except that it is not static.
918 * Created client_notify.c and moved the Notify packet handling
919 from the client.[ch] into that file.
921 * Created client_prvmsg.c and moved all private message and
922 private message key routines from the client.[ch] into that file.
924 * Create client_channel.c and moved all channel message and
925 channel private key routines from the client.[ch] into that file.
927 * Changed silc_client_get_client_by_id_resolve to resolve with
928 WHOIS command instead of IDENTIFY command, in the file
929 lib/silclient/idlist.c.
931 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Implemented the SKE's responder side to the Client library.
935 * When FAILURE is received to the protocol do not trust it
936 blindly. Register a timeout to wait whether the remote closes
937 the connection as it should do it, only after that process the
938 actual failure. This was changed to both client and server.
940 * Added client_internal.h to include some of the structures
941 there instead of client.h in lib/silcclient/.
943 * Added function silc_task_unregister_by_callback to unregister
944 timeouts by the callback function.
946 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Some "Incomplete WHOIS info" errors has been appearing on the
949 log files. Took away the entry->userinfo check from WHOIS
950 reply sending. The entry->userinfo is now " " if client did not
951 provide one. I thought this was fixed earlier but something
952 is wrong still. Let's see if the error still appears.
954 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Fixed a minor bug in the login when the channel key is
957 re-generated in the server. It used to generate the key in
958 wrong order and thus caused problems in the channel traffic.
960 * Fixed a minor bug in channel key distsribution after
961 KICK command. The key was not sent to the router even though
964 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Added silc_ske_process_key_material_data as generic routine
967 to process any key material as the SILC protocol dictates. The
968 function is used by the actual SKE library but can be used by
969 applications as well. This relates to the private message keys
970 and the channel private keys since they must be processed the
971 same way the normal SILC session keys. The protocol dictates
972 this. Affected files: lib/silcske/silcske.[ch].
974 Added also silc_ske_free_key_material to free the
975 SilcSKEKeyMaterial structure.
977 * Defined silc_cipher_set_key function to set the key for
978 cipher without using the object's method function. The affected
979 files: lib/silccrypt/silccipher.[ch].
981 * Implemented silc silc_client_add_private_message_key,
982 silc_client_add_private_message_key_ske,
983 silc_client_del_private_message_key,
984 silc_client_list_private_message_keys and
985 silc_client_free_private_message_keys functions in the
988 Added functions silc_client_send_private_message_key to send
989 the Private Message Key payload and silc_client_private_message_key
990 to handle incoming Private Message Key payload.
992 * Added Cipher field to the Private Message Key payload to set
993 the cipher to be used. If ignored, the default cipher defined
994 in the SILC protocol (aes-256-cbc) is used.
996 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Removed lib/silcclient/ops.h file.
1000 Redefined parts of the SILC Client Library API. Created new
1001 file silcapi.h that deprecates the ops.h file and defines the
1002 published Client Library API. Defined also private message key
1003 API and channel private key API into the file.
1005 This is the file that the application must include from the
1006 SILC Client Library. Other files need not be included by
1007 the application anymore.
1009 * Added new key_agreement client operation callback and also
1010 defined the Key Agreement library API for the application.
1012 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1015 is used by clients to request key negotiation between another
1016 client in the SILC network. If the negotiation is started it
1017 is performed using the SKE protocol. The result of the
1018 negotiation, the secret key material, can be used for example
1019 as private message key.
1021 Implemented the Key Agreement payload into the files
1022 lib/silccore/silauth.[ch].
1024 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Redefined ciphers for the SILC protocol. Added some new ciphers
1027 and defined the key lengths for the algorithms. Changed the
1028 code accordingly. The default key length is now 256 bits.
1030 * Fixed SKE key distribution function silc_ske_process_key_material
1031 when the key length is more than 128 bits. The default key
1032 length in SILC is now 256 bits.
1034 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1035 to indicate unsupported algorithm.
1037 * Renamed rijndael.c to aes.c and all functions as well.
1039 * Fixed a long standing channel key setting bug in client library.
1040 Weird that it has never surfaced before.
1042 * Fixed bug in channel deletion. If the entire channel is removed
1043 then it must also delete the references of the channel entry
1044 from the client's channel list as the client's channel entry and
1045 the channel's client entry share same memory.
1047 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Implemented CONNECT and SHUTDOWN commands in the client.
1051 * Implemented CLOSE command to the client.
1053 * Added the function silc_idlist_find_server_by_name into the
1054 files silcd/idlist.[ch].
1056 Added the function silc_idlist_find_server_by_conn into the
1057 files silcd/idlist.[ch].
1059 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * DIE command was renamed to SHUTDOWN. Updated the both code
1064 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1065 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1067 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1070 * Added function silc_server_create_connection function to create
1071 connection to remote router. My server implementation actually
1072 does not allow router to connect to normal server (it expects
1073 that normal server always initiates the connection to the router)
1074 so the CONNECT command is only good for connecting to another
1077 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1080 or some other client was kicked from the channel.
1082 Implemented the handling of the notify type to both client
1085 Implemented silc_server_send_notify_kicked to send the KICKED
1086 notify. It is used to send it to the server's primary router.
1088 * Implemented the KICK command into server and client.
1090 * Added `query' argument to the silc_idlist_get_client function
1091 to indicate whether to query the client from server or not if
1094 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1095 to indicate that the client is not channel founder.
1099 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Removed the rng context from SilcPacketContext structure and
1102 changed that the packet routine uses the Global RNG API.
1104 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * Added support for quit message that client can "leave" on the
1107 channel when it quits the SILC. It is ditributed inside the
1108 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1110 Added silc_server_free_client_data that will take the
1111 signoff message as argument.
1113 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1115 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Updated parts of the protocol specification to keep it up
1120 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1123 payloads in one packet.
1125 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1126 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1127 use now the new List flag.
1129 * Also deprecated the following packet types: REPLACE_ID,
1130 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1132 * Added list support for Notify packet in server.
1134 * Added silc_server_send_notify_channel_change to send the
1135 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1136 the silc_server_send_replace_id.
1138 * Added silc_server_send_notify_nick_change to send the
1139 NICK_CHANGE notify type. Deprecates the function
1140 silc_server_send_replace_id.
1142 * Added silc_server_send_notify_join to send the JOIN notify type.
1143 Deprecates the function silc_server_send_new_channel_user.
1145 * Added silc_server_send_notify_leave to send LEAVE notify type.
1146 Deprecates the function silc_server_send_remove_channel_user.
1148 * Added silc_server_send_notify_cmode and
1149 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1150 types. Deprecates the silc_server_send_set_mode function.
1152 * Added SERVER_SIGNOFF notify type to indicate that server has
1153 quit. This means that all clients on the channel from that
1154 server will drop. This can be also used when netsplit happens.
1156 Deprecated REMOVE_ID packet type since it is not needed anymore
1159 Added silc_server_send_notify_server_signoff to send the
1160 SERVER_SIGNOFF notify type. Deprecates the function
1161 silc_server_send_remove_id.
1163 Added also silc_server_send_notify_signoff to send the
1164 SIGNOFF notify type.
1166 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1167 SILC protocol from this day on. Changed the protocol
1168 specification as well.
1170 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1171 notify type. It is used between routers to notify about
1172 topic changes on a channel.
1174 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1177 * Partly updated the protocol specification to comply with the
1178 changes now made. It is still though a bit outdated.
1180 * The JOIN notify type now takes one extra argument <Channel ID>.
1181 The packet used to be destined to the channel but now the
1182 JOIN type may be sent as list thus it is impossible to
1183 destine it to any specific channel. By adding this argument
1184 it is again possible.
1186 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Added CREDITS file. The CHANGES and CREDITS file will appear
1189 in the distribution as well.
1191 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1194 types in the server's silcd/packet_receive.c.
1196 * Implemented CMODE and CUMODE to work in router environment.
1198 * Fixed minor encoding and decoding buglet from the
1199 lib/silccore/silcmode.c.
1201 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1204 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1206 * Changed all SilcConfigServer* and silc_config_server* to
1207 SilcServerConfig* and silc_server_config*, respectively.
1210 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Associated the ID (client or server ID) to the Authentication
1213 Payload to avoid any possibility of forging. Updated the
1214 protocol specification and the code accordingly.
1216 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * The RSA key length is now save to the RsaKey context in the
1219 key generation process in lib/silccrypt/rsa.c. The key length
1220 is now used to figure out the maximum size of the block allowed
1221 to be encrypted/signed.
1223 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1224 is equivalent to the silc_mp_mp2bin but does not allocate any
1227 * Changed silc_mp_mp2bin API to take length argument. If it is
1228 non-zero then the buffer is allocated that large. If zero, then
1229 the size is approximated using silc_mp_sizeinbase, which however
1232 * Created Global RNG API which is global RNG that application can
1233 initialize. After initializing, any routine anywhere in the
1234 code (including library) can use RNG without allocating a new
1235 RNG object. This was done to allow this sort of use of the
1236 RNG in code that has no chance to allocate RNG object. All
1237 applications currently allocate this and many routines in the
1238 library use this. Affected file lib/silccrypt/silcrng.[ch].
1240 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1241 it to use the Global RNG API.
1243 * Defined Authentication Payload into protocol specification that
1244 is used during SILC session to authenticate entities. It is
1245 used for example by client to authenticate itself to the server
1246 to obtain server operator privileges.
1248 Implemented this payload into the lib/silccore/silcauth.[ch].
1249 Implemented also routines for public key based authentication
1250 as the new protocol specification dictates.
1252 Moved definitions of different authentication methods from
1253 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1255 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1256 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1257 silc_pkcs_verify_with_hash functions into the file
1258 lib/silccrypt/silcpkcs.[ch].
1260 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * The client entry's userinfo pointer must be always valid.
1263 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1264 will fail since it requires the userinfo. Now, the userinfo
1265 is allocated as "" if actual userinfo does not exist. Actually,
1266 it must exist and it is totally Ok to drop client connections
1267 that does not announce the userinfo. However, we will make
1268 this workaround for now.
1270 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1271 to return the remote port by socket.
1273 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1276 SILC_SERVER_PENDING_EXEC and added an new macro
1277 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1278 data or when error occurs while processing the pending command.
1280 Added new argument `destructor' into silc_server_command_pending
1281 and to the SilcServerCommandPending object. This destructor is
1282 now called after calling the pending callback or if error occurs
1283 immediately. If error occurs the actual pending callback won't
1284 be called at all - only the destructor. The destructor may be
1285 NULL if destructor is not needed.
1287 All this applies for client library code as well. Similar
1288 changes were made there as well for the pending commands.
1290 In the client, the application must now allocate the
1291 SilcClientCommandContext with the silc_client_command_alloc
1294 * Added reference counter to the SilcServerCommandContext. Added
1295 function silc_server_command_alloc and silc_server_command_dup
1298 Same type of functions added to the client library for the same
1301 * Removed the cmd_ident from IDListData away since it is now
1302 global for all connections. It is the command identifier used
1303 in command sending and with pending commands. The affected file
1306 * Added reference counter to the SilcSocketConnection objecet to
1307 indicate the usage count of the object. The object won't be
1308 freed untill the reference counter hits zero. Currently only
1309 server uses this, and client ignores it. The client must be
1310 set to use this too later. The affected files are
1311 lib/silccore/silcsockconn.[ch]. Added also the function
1312 silc_socket_dup to increase the reference counter.
1314 This was mainly added because it is possible that the socket
1315 is removed underneath of pending command or other async
1316 operation. Now it won't be free'd and proper DISCONNECTING
1317 flags, etc. can be set to avoid sending data to connection that
1318 is not valid anymore.
1320 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1321 the connection. After that it sets SILC_SET_DISCONNECTED.
1322 It is, however, possible that the socket data is not still freed.
1323 The silc_server_packet_process now checks that data is not
1324 read or written to connection that is DISCONNECTED. The socket
1325 get's freed when the reference counter hits zero.
1327 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Changed the client operation API: channel_message operation's
1330 `sender' is now the client entry of the sender, not the nickname
1331 and the `channel' is the channel entry, not the channel name.
1333 In the private_message operation the `sender' is now also the
1334 client entry of the sender not the nickname.
1336 Affected file is lib/silcclient/ops.h and all applications
1337 using the client operations.
1339 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Moved the calling of ops->connect() from connect_to_server_final
1342 into receive_new_id functin since that is the point when the
1343 client is actually allowed to send traffic to network. The
1344 affected file is lib/silcclient/client.c.
1346 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1349 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1350 (if needs broadcasting) instead of broadcasting the packets one
1351 by one which would make a burst in the network traffic.
1353 * Added `broadcast' argument to the functions in silcd/server.[ch]
1354 silc_server_create_new_channel[_with_id] to indicate whether
1355 to send New Channel packet to primary router.
1357 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Added new function into the silcd/server.[ch] files:
1360 silc_server_create_new_channel_with_id to create new channel with
1361 already existing Channel ID.
1363 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1364 lib/silccore/silcpacket.h. This packet is used t send list of
1365 Set Mode payloads inside one packet. Server uses this to set
1366 the modes for the channels and clients on those channels, that it
1367 announced to the router when it connected to it. The protocol
1368 specification has been updated accordingly.
1370 * The silc_server_new_channel did not handle the packet coming
1371 from normal server as it normally does not send that. However,
1372 when it announces its channels it does send it. Implemented
1373 the support for that.
1375 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1376 into the file lib/silccore/id.h.
1378 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Fixed memory leaks in the functions silc_idlist_del_client,
1381 silc_idlist_del_channel and silc_idlist_del_server in the file
1382 silcd/idlist.c. All of those leaked like a sieve.
1384 * Fixed some small memory leaks in the client's function
1385 silc_client_notify_by_server.
1387 * Added functions into silcd/server.c: silc_server_announce_clients,
1388 silc_server_announce_channels and silc_server_announce_server.
1389 These functions are used by normal and router server to announce
1390 to its primary router about clients, channels and servers (when
1391 router) that we own. This is done after we've connected to the
1394 These functions effectively implements the following packet types:
1395 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1396 and SILC_PACKET_NEW_ID_LIST.
1398 * Added new functions into the silcd/packet_receive.[ch]:
1399 silc_server_new_id_list, silc_server_new_channel_list and
1400 silc_server_new_channel_user_list to handle the incoming
1401 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1403 * Added support of changing Channel ID in the function
1404 silc_server_replace_id. If the server that announces a channel
1405 to the router already exists in the router (with same name but
1406 with different Channel ID), router is responsible to send
1407 Replace ID packet to the server and force the server to change
1408 the Channel ID to the one router has.
1410 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1411 client that the Channel ID has been changed by the router. The
1412 normal server sends this to the client. Client must start using
1413 the new Channel ID as the channel's ID.
1415 Implemented handling of this new type into lib/silcclient/client.c
1416 into the function silc_client_notify_by_server.
1418 * Added new function silc_idlist_replace_channel_id into the files
1419 silcd/idlist.[ch] to replace the Channel ID.
1421 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Call silc_server_command_identify_check always when processing
1424 the IDENTIFY command in silcd/command.c
1426 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1429 send keepalive packets. The packet can be sent by clients,
1430 servers and routers.
1432 Added function silc_socket_set_heartbeat into the file
1433 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1434 If not set, the heartbeat is not performed. The actual
1435 heartbeat is implemented in the low level socket connection
1436 library. However, application is responsible of actually
1439 Added silc_server_send_heartbeat to send the actual heartbeat
1440 packet into silcd/packet_send.[ch]. Server now performs
1441 keepalive with all connections.
1443 * Added silc_task_get_first function into lib/silcutil/silctask.c
1444 to return the timeout task with shortest timeout. There was a bug
1445 in task unregistration that caused problems. TODO has been
1446 updated to include that task system must be rewritten.
1448 * The client library will now resolve the client information when
1449 receiving JOIN notify from server for client that we know but
1450 have incomplete information.
1452 * Rewrote parts of silc_server_remove_from_channels and
1453 silc_server_remove_from_one_channel as they did not remove the
1454 channel in some circumstances even though they should've.
1456 * Encryption problem encountered in server:
1458 The LEAVE command used to send the Channel Key packet to the
1459 router immediately after generating it. However, the code
1460 had earlier sent Remove Channel user packet but not immediately,
1461 ie. it was put to queue. The order of packets in the router
1462 was that Channel Key packet was first and Remove Channel User
1463 packet was second, even though they were encrypted in the
1464 reverse order. For this reason, MAC check failed. Now, this
1465 is fixed by not sending the Channel Key packet immediately but
1466 putting it to queue. However, this is more fundamental problem:
1467 packets that are in queue should actually not be encrypted
1468 because packets that are sent immediately gets encrypted
1469 actually with wrong IV (and thus MAC check fails). So, packets
1470 that are in queue should be encrypted when they are sent to
1471 the wire and not when they put to the queue.
1473 However, the problem is that the current system has not been
1474 designed to work that way. Instead, the packet is encrypted
1475 as soon as possible and left to the queue. The queue is then
1476 just purged into wire. There won't be any fixes for this
1477 any time soon. So, the current semantic for packet sending
1480 o If you send packet to remote host and do not force the send
1481 (the packet will be in queue) then all subsequent packets to the
1482 same remote host must also be put to the queue. Only after the
1483 queue has been purged is it safe again to force the packet
1486 o If you send all packets immediately then it safe to send
1487 any of subsequent packets through the queue, however, after
1488 the first packet is put to queue then any subsequent packets
1489 must also be put to the queue.
1491 Follow these rules and everything works fine.
1493 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * Added new function silc_server_remove_clients_by_server to
1496 remove all client entries from ID list when the server connection
1497 is lost. In this case it is also important to invalidate all
1498 client entires as they hold the invalid server entry. This
1499 fixes fatal bug when server has lost connection and will reconnect
1502 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1504 * Made some sanity checks to silc_server_daemonise like to check
1505 whether the requested user and group actually exists.
1507 * Added sanity check to SKE's silc_ske_responder_finish to check
1508 that the public and private key actually is valid.
1510 * Invalidate the client's nickname when receiving Replace ID
1511 packet and the Client ID is being replaced. This means that the
1512 server will query the nickname if someone needs it (client)
1515 * Sort the ID Cache in client library when the ID Cache data
1516 has changed (needs sorting).
1518 * Do not allow for SILC client to create several connections to
1519 several servers. The client does not support windows right now
1520 and generating multiple connections causes weird behaviour.
1522 Irssi-silc client does support windows and can handle several
1523 connections without problems, see: www.irssi.org and SILC plugin.
1525 * Fixed some places where client was added to the IDList. The
1526 rule of thumb is following (in order to get everything right):
1527 If the client is directly connected local client then the
1528 `connection' argument must be set and `router' argument must be
1529 NULL to silc_idlist_add_client function. If the client is not
1530 directly connected client then the `router' argument must
1531 bet set and the `connection' argument must be NULL to the
1532 silc_idlist_add_client function.
1534 * The funtion silc_server_packet_send_local_channel actually did
1535 not check whether the client was locally connected or not. It
1536 does that now. Fixed a bug related to LEAVE command.
1538 * Fixed Remove Channel User payload parsing bug in server's
1539 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1541 * The server's silc_server_save_channel_key now checks also the
1542 global ID list for the channel as it might not be in the local
1543 list. Fixed a bug related to LEAVE command.
1545 * Is this the end of the [<unknown>] buglet that has been lurking
1546 around for a long time? A little for loop fix in server's
1547 silc_server_command_whois_parse that is used by both IDENTIFY
1548 and WHOIS command. At least, this was a clear bug and a cause
1549 of one type of [<unknown>] buglet.
1551 * WHOIS and IDENTIFY commands call the function
1552 silc_server_command_[whois/identify]_check function even if
1553 we are not router server.
1555 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * Added --with-gmp configuration option. If set the GMP
1558 is always compiled in the SILC source tree. If not set then
1559 it is checked whether the system has the GMP3 installed. If
1560 it has then the GMP won't be compiled (the system's headers
1561 and library is used), if it doesn't have it then the GMP is
1562 compiled in the SILC source tree.
1564 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Changed RSA private exponent generation to what PKCS #1
1567 suggests. We try to find the smallest possible d by doing
1568 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1569 not security fix but optimization.
1571 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Added new config entry [Identity] to fork the server and run
1574 it as specific user and group. A patch from Bostik.
1576 * Imported Dotconf configuration library into lib/dotconf.
1577 This will be used to create the SILC configuration files later.
1578 It will appear in the distsribution after this commit.
1580 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * A big code auditing weekend happening. Auditing code for
1583 obvious mistakes, bugs and errors. Also, removing any code
1586 Removed files for being obsolete:
1588 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1589 inline in the file lib/silcutil/silcbuffer.h)
1591 o lib/silcutil/silcbufutil.c (the header has inline versions)
1593 Changed code to fix possible error conditions:
1595 o The buffer formatting routines now check that the destination
1596 buffer really has enough space to add the data. This applies for
1597 both buffer formatting and unformatting
1598 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1599 unformatting was changed to accomodate following rules:
1600 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1601 sent to the function while XXX_*STRING will not allocate or copy
1602 the data into the buffer. Instead it sets the pointer from the
1603 buffer into the pointer sent as argument (XXX_*STRING used to
1604 require that the pointer must be allocated already). This change
1605 makes this whole thing a bit more consistent and more optimized
1606 (note that the data returned in the unformatting with XXX_*STRING
1607 must not be freed now). The routines return now -1 on error.
1609 o Tried to find all code that use buffer_format and buffer_unformat
1610 and added return value checking to prevent formatting and
1611 especially unformatting errors and possible subsequent fatal
1614 o Changed ske->x and ske->KEY to mallocated pointers in
1615 lib/silcske/silcske.h. Fixed possible data and memory leak.
1617 o Added return value checking to all *_parse* functions. Fixed
1618 many memory leaks as well.
1620 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1621 so that buffer overflows would not happen. All code now also
1622 checks the return value as it can fail.
1624 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1626 * Added reconnection support to server if the normal server looses
1627 its connection to the router (for example if router is rebooted).
1628 The server performs normal reconnection strategy implemented
1629 to the server. Affected file silcd/server.c.
1631 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Added new packet type SILC_PACKET_SET_MODE that is used to
1634 distribute the information about changed modes (for clients,
1635 channels and clients channel modes) to all routers in the
1636 network. Updated the protocol specification accordingly.
1638 Added functions into silcd/packet_send.c and
1639 silcd/packet_receive.c: silc_server_send_set_mode,
1640 silc_server_set_mode.
1642 Added new files silcmode.[ch] into lib/silccore that implements
1643 the encoding and decoding of Set Mode Payload. Added new type
1644 SilcSetModePayload. Moved the definitions of different modes
1645 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1647 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Oops, a little mistake in server's connection authentication
1650 protocol. The protocol is not ended with FAILURE but with
1651 SUCCESS if the authentication is Ok. :) Affected file is
1654 * Implemented NICK_CHANGE notify handling in server in the file
1655 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1656 the local clients on the channel. After the changing nickname
1657 in router environment snhould work and the [<unknown>] nickname
1658 should appear no more.
1660 The silc_server_replace_id function that receives the Replace ID
1661 payload now sends the NICK_CHANGE notify type also in the file
1662 silcd/packet_receive.c
1664 * Changed WHOIS and IDENTIFY command to support the maximum amount
1665 of arguments defined in protocol specs (3328 arguments). This
1666 fixed a bug that caused problems when there were more than three
1669 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Added extra parameter, command identifier, to the
1672 silc_client_send_command so that explicit command identifier
1675 Changed that ID list routines uses specific command identifier
1676 when sending WHOIS/IDENTIFY requests to the server so that they
1677 can be identified when the reply comes back.
1679 Affected files lib/silcclient/command.[ch],
1680 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1682 * Added `sender' argument to silc_server_packet_send_to_channel
1683 to indicaet the sender who originally sent the packet to us
1684 that we are now re-sending. Ignored if NULL. Affected file
1685 silcd/packet_send.[ch].
1687 * Added some server statistics support in silcd/server_internal.h
1688 SilcServerStatistics structure and around the server code. Also
1689 send some nice statistics information when client is connecting
1692 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Fixed channel ID decoding in server's JOIN command reply in
1695 silcd/command_reply.c
1697 * Fixed braodcasting of replace ID payload to not to send it if
1698 we are standalone server in silcd/packet_receive.c.
1700 * Fixed all channel message sending routines to not to send
1701 packets to clients that has router set, since they are routed
1702 separately in the same function earlier. Affects file
1703 silcd/packet_send.c and all channel packet sending functions.
1705 * In USERS reply, res_argv[i] are not allocated, the table
1706 is allocated. Thus changed that free the table, not its
1709 * In server's whois_check and identify_check if the client is
1710 locally connected do not send any WHOIS commands - they are not
1713 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Fixed some minor bugs in client when sending WHOIS command. The
1716 arguments was in wrong order.
1718 * Removed statis function add_to_channel from server in
1719 silcd/command.c that was previously used with the joining but
1722 * Tested USERS command in router environment successfully with two
1723 routers, two servers and two clients.
1725 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1727 * Reorganized the USERS command and command reply in client library
1728 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1729 When the command is given by user we register a pending command
1730 callback that will reprocess the command after the reply has been
1731 received from the server. When reprocessing the packet we then
1732 display the information. Thus, the USERS information is displayed
1733 now in the command callback instead of in the command reply
1734 callback. The processing of the command is same as previously
1735 when server has sent the command reply in the JOINing process.
1737 * Added to USERS command in silcd/command_reply.c to join the client,
1738 we didn't use to know about, to the channel after we've created
1739 a client entry for it. Also, for clienet we did know already still
1740 check whether it is on the channel or not and add it if not.
1742 * Removed silc_server_command_join_notify as the function and its
1745 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Changed the client's pending command handling to the same as the
1748 server's pending command handling. It is also now possible to
1749 execute command reply functions from other command reply
1750 function as the function callbacks for commands and command
1751 replies are one and same. The pending commands are not static
1752 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1753 in client connection context. Thus, pending commands are server
1754 connection specific as it is convenient.
1756 Changed the function silc_client_command_pending and
1757 silc_client_command_pending_del and added new function
1758 silc_client_command_pending_check. Removed the
1759 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1762 * Added cmd_ident, current command identifier, to the client
1763 connection context in lib/silcclient/client.h to keep track on
1764 command identifiers used in command sending. Client's command reply
1765 function handling now supports the mandatory command identifiers.
1767 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1768 funtions in client to fully support pending command callbacks.
1770 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1771 as one of the arguments to the application in the command reply
1774 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1775 before first releasing SILC but came back. Now it is removed again
1776 and should come back nomore. The FORWARDED flag was used only
1777 by the JOINing procedure by forwarding the command packet to router.
1778 Now, the JOINing procedure has been changed to more generic (due
1779 to various router environment issues) and FORWARDED is not needed
1780 anymore for anything. The protocol specification is yet to be
1783 Now, removed silc_server_packet_forward from server and the flag
1784 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1786 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Renamed NAMES command to USERS command. The NAMES was named that
1789 due to historical reasons. Now it is renamed. Also, rewrote
1790 parts of the USERS command. The nickname list is not sent anymore
1791 by the server. Only Client ID and mode lists are sent in the USERS
1792 command. Changed this also to the protocol specification.
1794 The client now resolves the names and stuff after it receives
1795 the USERS list from the server when joining to the channel.
1797 * WHOIS and IDENTIFY commands has been changed to support multiple
1798 Client ID's per command. One can now search for multiple users
1799 in the network by sending only one WHOIS or IDENTIFY command.
1800 Changed the code and the protocol specifications.
1802 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1803 uses silc_server_command_whois_parse to parse the request. */
1805 * If normal server, do not parse the WHOIS and IDENTIFY requests
1806 before sending it to the router. Saves some time.
1808 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Fixed JOIN command on client library. Wrong number of arguments
1811 used to crash the client.
1813 * Added silc_server_channel_has_global function to check whether
1814 channel has global users or not.
1816 * Added silc_server_channel_has_local function to check whether channel
1817 has locally connected clients on the channel.
1819 * The silc_server_remove_from_one_channel now checks whether the
1820 channel has global users or not after given client was removed from
1821 the channel. It also checks whether the channel has local clients
1822 on the channel anymore. If it does not have then the channel entry
1823 is removed as it is not needed anymore.
1825 * The silc_server_notify now checks on JOIN notify whether the joining
1826 client is one of locally connected or global. If it is global then
1827 the channel has now global users on the channel and that is marked
1828 to the channel entry. Also, it now saves the global client to
1829 global list who is joining and JOINs it to the channel. This is
1830 for normal server, that is.
1832 Changed silc_server_send_notify_on_channel,
1833 silc_server_packet_relay_to_channel and
1834 silc_server_packet_send_to_channel check if we are normal server
1835 and client has router set (ie. global client) do not send the
1836 message to that client, as it is already routed to our router.
1838 * Implemented LEAVE notify type handling in silc_server_notify
1841 * Tested LEAVE command in router environment successfully. Tested
1842 with two routers, two servers and two clients.
1846 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1848 * Implemented SIGNOFF notify type handling in silc_server_notify
1851 * silc_server_remove_id now removes the client entry from all channels
1852 it has joined and thusly sends SIGNOFF notify type.
1854 * Rewrote the NAMES list generation in server by removing two excess
1855 loops. The lists are created now inside one loop.
1857 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * silc_server_remove_channel_user checks now also global list
1860 for channel and client.
1862 * silc_server_new_channel_user checks now both local and global
1863 list for channel and client. Fixed a bug in client id decoding.
1864 Used to decode wrong buffer.
1866 * silc_server_channel_message checks now both local and global
1867 list for channel entry.
1869 * Tested channel joining (hence JOIN) in router environment
1870 successfully. Tested with two routers, two servers and two
1873 * Tested channel message sending in router environment successfully.
1875 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added silc_server_save_channel_key into server.[ch] to save the
1878 received channel key in Channel Key payload processing. It is
1879 also used in JOIN command reply handling.
1881 Equivalent function silc_client_save_channel_key added into
1882 client.[ch] into client library.
1884 * Changed JOIN command reply to send information whether the channel
1885 was created or not (is existing already) and the channel key
1886 payload. Changed protocol specs accordingly.
1888 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1889 the request was sent by ID and not by nickname. Crashed on
1892 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1895 now correctly save the received data.
1897 * silc_server_free_sock_user_data now notifies routers in the
1898 network about entities leaving the network.
1900 At the same time implemented functions silc_server_remove_id
1901 and silc_server_send_remove_id to receive and send REMOVE_ID
1902 packets. The packet is used to notify routers in the network
1903 about leaving entities. The ID removed will become invalid in
1906 * Added function silc_idlist_del_server into server. Removes and
1907 free's server entry from ID list.
1909 * silc_server_private_message function now checks, if we are router,
1910 that the destination ID really is valid ID, naturally.
1912 * In router when NEW_ID packet is received (for new client) the
1913 hash of the Client ID is saved in the ID Cache but the
1914 client->nickname is set to NULL, instead of putting the hash
1917 IDENTIFY command now also checks that client->nickname must be
1918 valid. If it is not if will request the data from the server who
1919 owns the client. Added new function
1920 silc_server_command_identify_check.
1922 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1923 to set the command to already allocated Command Payload.
1925 * Tested private message sending in router environment with two
1926 routers, two servers and two clients. Fixed minor bugs and now
1929 * Fixed segfault from client's NAMES command. Used to crash if
1932 * Forwarded packets must not be routed even if it is not destined
1933 to the receiver. Changed server code comply with this.
1935 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added `require_reverse_mapping' boolean value to ServerParams
1938 structure. If TRUE (not default) the server will require that
1939 the connecting host has fully qualified domain name.
1941 If the reverse mapping is not required and hostname could not be
1942 found the IP address is used as hostname.
1944 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Implemented version string checking to both client and server.
1947 The check is incomplete currently due to the abnormal version
1948 strings used in development version of SILC.
1950 * Changed all command functions in server to use the new
1953 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Changed char *data to unsigned char *data in ID Cache system to
1956 support binary data as ID Cache data. Changed code to support
1957 binary data in lib/silccore/idcache.c.
1959 * Renamed silc_server_packet_relay_command_reply to
1960 silc_server_command_reply as it is normal packet receiving
1961 function. Rewrote the function to accept command replys for
1962 servers and not only for clients.
1964 * Mark remote router always as registered server if we are connecting
1965 to it. Otherwise, commands sent by the router to us are ignored.
1967 * All ID List find routines now returns the ID Cache Entry pointer
1968 as well if requested.
1970 * WHOIS command works now in router environment, tested with two
1971 routers, two servers and two clients.
1973 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1974 in router environment (as it is almost equivalent to WHOIS) but
1975 hasn't been tested thoroughly. Added new functions:
1977 silc_server_command_identify_parse
1978 silc_server_command_identify_send_reply
1979 silc_server_command_identify_from_client
1980 silc_server_command_identify_from_server
1982 * Disabled route cache adding because adding two different ID's with
1983 same IP replaces the old cache entry thus giving wrong route.
1984 The entry->router->connection is always the fastest route anyway
1985 so route cache may not be needed. Of course, new routes maybe
1986 established after receiving the ID when the entry->router->connection
1987 might not be anymore the most optimal.
1989 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Add route cache for received ID for fast routing.
1993 * Added silc_server_packet_route to route received packet on router
1994 that is not destined to us.
1996 * Renamed silc_server_get_route to silc_server_route_get.
1998 * Added id_string and id_string_len fields into SilcServer to
1999 include encoded ServerID for fast comparing without excess
2000 encoding of the ID's.
2002 * Cleaned up WHOIS command on server side. Added following static
2005 silc_server_command_whois_parse
2006 silc_server_command_whois_check
2007 silc_server_command_whois_send_reply
2008 silc_server_command_whois_from_client
2009 silc_server_command_whois_from_server
2011 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2012 arguments in command replies. All command functions should be
2013 updated to use this macro.
2015 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Minor typo fixes on command reply handling on server.
2019 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Added silc_server_command_add_to_channel internal routine to add
2022 the client to the channel after router has created the channel and
2023 sent command reply to the server.
2025 * Added generic silc_server_send_command to send any command from
2028 * Use static buffer with ID rendering instead of duplicating data.
2030 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Fixed a channel user mode bug when joining to a channel server gave
2033 everybody channel founder rights, oops.
2035 * We mark ourselves as the router of the incoming server connection
2036 if we are router ourselves. This way we can check in some packet
2037 sending functions whether it is locally connected server. For
2038 incoming router connections we put NULL.
2040 * For router sending packets locally means now always sending the
2041 packet cell wide; to local clients and local servers. For normal
2042 server sending packet locally means sending it to only local
2045 * Fixed the JOIN command to really work in router environment. If the
2046 channel is created it is always created by the router. Router is
2047 also responsible of making the initial joining to the channel,
2048 sending JOIN notify to the sending server and distributing
2049 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2050 does not exist server doesn't do anything else but forward the
2051 command to the router which performs everything.
2053 * Added silc_server_send_channel_key function to send the Channel Key
2056 * Added silc_server_create_channel_key to create new channel key. The
2057 channel key is now re-generated everytime someone joins or leaves
2058 a channel, as protocol dictates. Note: channel->key_len is the
2061 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2064 packet_receive.[ch] to separate packet sending and receiving
2065 routines. The server.[ch] now includes everything else including
2066 actual packet processing (writing and reading data) and other
2069 Renamed silc_server_private_message_send_internal to
2070 silc_server_send_private_message. The routine is still though
2071 used only to relay private messages as server does not send
2072 private messages itself.
2074 Renamed silc_server_new_channel to silc_server_create_new_channel
2075 and added new function sicl_server_new_channel that handles the
2076 incoming New Channel packet. Added also new sending function
2077 silc_server_send_new_channel to send New Channel Payload.
2079 * Added new function silc_server_notify to process incoming notify
2080 packet to the server/router. Server may then relay the notify
2081 to clients if needed.
2083 * Added new function silc_server_new_channel_user to process incoming
2084 New Channel User packet. Router will redistribute the packet and
2085 send JOIN notify to its local clients and locally connected servers
2086 if needed. Normal server will send JOIN notify to its local client
2087 on same channel when received this packet. Added also corresponding
2088 sending function silc_server_send_new_channel_user to sent the
2091 * Added boolean route argument to send_notif_to_channel and
2092 packet_send_to_channel functions to attempt to route the packet
2093 if it is TRUE and send only locally if it is FALSE.
2095 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * silc_server_replace_id now broadcasts the received replace ID
2098 packet if it is not broadcast packet already. The router must
2099 broadcast to inform other routers about changed ID.
2101 * Added backpointer to server's router into SilcServer context in
2102 silcd/server_internal.h.
2104 * Fixed silc_server_packet_broadcast to send correct broadcast
2107 * The channel key is now distributed to the local client as soon
2108 as it is received from the router (in router environment) so that
2109 no other packet may be sent for the channel until client has
2112 * silc_server_remove_channel_user now broadcasts the received
2113 Remove Channel User packet if it is not broadcast packet already.
2114 The router must broadcast to inform other routers about removed
2117 * Added users field into SilcPacketContext that is a reference count
2118 of the context. One can increase the reference count by calling
2119 silc_packet_context_dup which is now changed to just increase the
2120 reference count instead of duplicating the data. The reference
2121 count is decresed by calling silc_packet_context_free that will
2122 free the data after the reference count hits zero.
2124 For now on the packet context and everything allocated into it
2125 (including the raw packet from network) must be freed by calling
2126 the new silc_packet_context_free function. Added also new function
2127 silc_packet_context_alloc that must be used now to allocate the
2128 context. This also means that if a routine is asynchronous from
2129 silc_[client/server]_packet_parse_type the packet context must
2130 be duplicated by calling silc_packet_context_dup. Otherwise it
2131 gets free'd after silc_[client/server]_packet_parse_type returns.
2132 Also, one must remember that if packet is duplicated then its
2133 reference count must be decresed by calling the free function as
2134 many times as it was duplicated.
2136 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2137 from both client and server.
2139 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Made joining to a channel working in router environment.
2143 * Cleaned up JOIN command on server side and create function
2144 silc_server_command_join_channel internal routine to make the
2147 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Changed silc_command_pending list to SilcDList. Also, added
2150 `ident' field to SilcServerCommandPending structure to identify
2151 the reply and to call correct callback.
2153 Added silc_server_command_pending_check function to replace the
2154 corresnponding macro. The silc_command_pending list is not
2157 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2158 to set identifier to previously allocated Command Payload. It
2159 is used to set identifier for command when resending Command
2162 * Added silc_command_payload_encode_payload to encode Command
2163 Payload buffer from SilcCommandPayload structure.
2165 * Added silc_argument_payload_encode_payload to encode Argument
2166 payload buffer from SilcArgumentPayload structure.
2168 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Changed WHOIS command to support router connection on server side.
2171 The whois request is always sent to router unless the server is
2172 standalone server. After server has received the reply from the
2173 router will it send the reply to the client.
2175 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2176 broadcast received broadcast packet. The function is used only
2177 by router. The broadcast packet is always sent to the router's
2180 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2181 render given ID to printable string, for log files for example.
2183 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2185 * Made basic router to router connections working. At least they
2186 can now connect to each other but nothing really works the way
2187 they are supposed - yet.
2189 * Added new initiator token to RouterConnection configuration
2190 file in silcd/serverconfig.[ch]. It is used to tell whether we
2191 are the initiator to the remote router or whether we'll expect
2192 the other end to connect.
2194 * Moved registering of listener task to silc_server_init, hence
2195 the server starts listenning as soon as it is run, even if it
2196 does not have connections to other routers. Let's see how well
2199 * Changed default connection retry timeouts for more suitable in
2202 * Removed cipher and such arguments from silc_idlist_add_client
2203 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2204 Added new function silc_idlist_add_data to add the keys and stuff
2207 * Added SilcIDListData structure and added it to SilcClientEntry
2208 and SilcServerEntry as their first field in the structure. This
2209 way we can explicitly cast the ID entries to the SilcIDListData
2210 structure and get common data for the entries. In past, we had
2211 to first check what type of connection it is and then cast it to
2212 correct ID entry type. Now, we can directly cast the opaque
2213 pointer to the SilcIDListData (no matter what ID entry it actually
2214 is) and get the data needed.
2216 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2219 in some circumstances even if threre were timeout tasks, though not
2220 IO tasks, but tasks anyway. Now fixed.
2222 * Defined SilcServerConnection structure to hold connection specific
2223 stuff about directly connected servers and routers. The definition
2224 is currently in silcd/server_internal.h. I thought about having
2225 a bit more important role fro this struct but for now it is used
2226 only when connecting to other server (or router actually).
2228 * Added connecting retry support in server when connecting to
2229 router(s). The retry feature implement exponential backoff
2230 algorithm. Also, added SilcServerParams structure to hold default
2231 parameters for server. For now, it include these retry settings
2232 and are hard coded. After server is moded to be as Silc Server
2233 Library this structure will be more important.
2235 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Changed client librarys channel->clients table to SilcList and
2238 changed code accordingly.
2240 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Changed client's channel table to SilcList and changed code
2243 accordingly. Also changed SilcChannelClientEntry to include back-
2244 pointer to the channel so that client entry can use that structure
2245 as list as well and we have fast cross-reference to the channel.
2246 This change dramatically decreased the complexity of channel
2247 handling with client entry and vice versa (removed one extra
2248 loop when searching for channel entry from many functions).
2250 * Changed server->sim from table to SilcDList and changed code
2253 * NAMES command can now be used from user interface. It will show
2254 the user list on the channel, neatly.
2256 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2257 Code now saves realname of the user if it becomes available.
2259 * Renamed configure.in to configure.in.pre and made ./prepare
2260 script to automatically add correct version string to
2261 configure.in which it creates from configure.in.pre.
2263 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * NAMES command reply now shows users mode with the nickname when
2268 * Moved silc_client_ch[u]mode[_char] functions from
2269 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2270 place sucks, they are utility functions and should be in some
2273 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2275 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2278 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Added TRQ (efficient deque and list library) into lib/trq. This is
2283 a very good list library that is currently used in the SILC. Defined
2284 SilcList API over the library because I didn't like the API very
2285 much. See lib/trq/silclist.h for the API and examples of how to
2286 use the API. Fixed various places in the code to use the new
2287 SilcList API. The SilcList is meant for lists that has a structure
2288 already defined as a list. It is not suitable to add just some
2289 context to the list (in TRQ, the context is the list actually).
2291 So, I defined SilcDList that can be used for the purpose where
2292 predefined list structure does not exit. This can be used as
2293 such list. Now some context just can be added to the SilcDList.
2294 Currently this list is not used in the SILC just yet, though there
2295 are a lot places where this can replace dynamically allocated
2296 tables and I will fix these places, later, to use SilcDList.
2297 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2298 and use TRQ internally).
2300 Also fixed some annoying warning messages that the original TRQ
2301 code generated. Also minor changes to TRQ's Makefile.in.
2303 * Added support for querying by Client ID to both WHOIS and
2304 IDENTIFY commands into server, as required by the protocol.
2306 * Removed method function pointers from SilcBuffer structure. They
2307 weren't used to anything and just increased the context size for
2308 no good reason. This change also made silc_buffer_alloc and
2309 silc_buffer_free functions inline functions.
2311 * Disabled command flooding detection support until it's fixed so
2312 that it accepts commands in but does not execute them more than once
2315 * Added silc_net_localhost(), to return local hostname, into
2316 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2317 that must be initialized before calling silc_client_init.
2319 * Added new function: silc_server_send_notify_on_channels to send
2320 notify messages to all channels client has joined. It is assured
2321 that the message is sent only once per client.
2323 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2324 lib/silcutil/silcutil.[ch] as silc_format function. The new
2325 function is generic and is used by server as well, not only by
2326 the logging routines.
2328 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2329 the provided version string was not acceptable. Added new function:
2330 silc_ske_check_version into lib/silcske/silcske.h. The function
2331 must be implemented by the application (client or server) and it
2332 does not reside in the SKE library. The function checks the version
2333 string remote end sent.
2335 * Added back pointers (to opaque context and to SilcSocketConnection)
2336 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2338 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2339 duplicate packet context structure.
2341 * Changed `notify' client operation to send same arguments as client
2342 receives from server except for ID's. ID's are mapped to correct
2343 ID entry and that is returned. Also, if channel entry is not sent
2344 by server but the notify is for channel the channel entry is sent
2345 to application (otherwise application doesn't know that it is for
2346 channel (library gets it from packet's Destination ID)).
2348 * Added silc_client_remove_from_channels into client library to
2349 remove a client from all channels it has joined to. Used when
2350 received SIGNOFF notify from server. Added also new function
2351 silc_client_replace_from_channels to replace old ID entry with
2352 new ID entry on all channels. Used when received NICK_CHANGE
2355 * Fixed ID Cache list handling in silc_idlist_get_client in
2356 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2357 to get (or query) client by ID.
2359 * Updated TODO list.
2361 * Added connection authentication status message defined by the
2362 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2363 support for these into the code in client and server side.
2365 * Added generic function silc_client_send_command to send any command
2366 with variable argument list. Application should use this function
2367 to send commands if the command functions provided by the library
2368 does not suite for the application's user interface needs.
2370 * Added new `failure' client operation. Application is notified about
2371 received failure packet if client is executing a protocol. In this
2372 case the protocol's execution has failed.
2374 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2375 is required by the protocol.
2377 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2378 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2381 * Added status flag to SilcSKE object to indicate realtime status
2382 of the SKE protocol.
2384 * Application receives now exactly same command reply arguments as
2385 the library receives from server. However, if ID is received the
2386 corresponding ID entry is returned to the application (eg. Client
2387 ID is mapped to correct SilcClientEntry entry and that is returned).
2388 Changed command_reply client operation due to this change.
2390 * Changed all ID's in commands and in command replys as ID Payloads.
2391 Change affected both client and server side codes.
2393 All ID's sent in SILC network (with execption of ID's in SILC
2394 Packet header) are sent in ID Payload to support variable length
2397 * Server now notifies nick changes and notifies all clients on
2398 the channels about the new nickname (about the new Client ID,
2401 * Implemented CMODE command to change channel modes. Supports all
2402 channel modes defined by the protocol specs except ban and invite
2403 lists. (Also, private channel key mode is supported but support for
2404 setting private channel key in client is missing, thus, this mode
2405 has no effect on client side (except that server requires that the
2406 client uses private channel key and normal channel traffic does not
2409 Also, invite mode works per se, but INVITE command does not work
2410 yet correctly, so you can set channel as invite only channel but
2411 inviting clients to the channel does not work (it is yet to be
2412 thought what's the best way to do it).
2414 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2415 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2416 Implemented CUMODE command to change user's mode on the channel.
2417 Supports all modes defined by the protocol specs.
2419 * Added NAMES command reply to return users modes on the channel.
2421 * Removed unnecessary and slow ciphers from lib/silccrypt.
2423 * Set SO_KEEPALIVE option to connection sockets by default.
2425 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2427 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2428 redefined the Notify Payload into protocol specs.
2430 * Added silc_id_payload_parse_id to get ID directly from raw
2433 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2436 accept searching by Client ID as well.
2438 * Added support for LEAVE and SIGNOFF notify types in client library.
2440 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2441 to parse ID Payload from raw data.
2443 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Added flags parameter into silc_ske_assemble_security_properties
2446 function in lib/silcske/silcske.[ch].
2448 * Changed notify client operation to fit better for notify messages
2449 sent by server. The notify payload received from server is now
2450 passed to the application (after parsing it to SilcNotifyPayload).
2451 It is application's responsibility to retrieve the arguments
2452 from the payload and show the message the way it wants. The message
2453 sent by server is implementation specific.
2455 * Changed public keys to comply with the protocol specification.
2456 Old public keys are not supported anymore and are not compatible.
2458 * Removed nickname from Channel Payload as the latest draft removed
2459 it. The client must resolve the nickname from the NAMES command
2460 reply received when it joined the channel.
2462 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2464 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Fixed some errors in protocol specification drafts.
2468 * Created lib/silccore/silcnotify.c to implement Notify Payload
2469 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2470 generic payloads described by protocol specifications. The file
2471 includes implementations for ID Payload and Argument Payload.
2473 * Changed Command Payload implementation to use the new Argument
2474 Payload. Changed command_xxxx_payload to command_payload_xxxx
2475 to comply with SILC coding conventions.
2477 * Added suppport for Argument Payload handling in Notify Payload
2478 implementation as protocol requires it. Added the new support
2479 into server and client lib as well.
2481 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Added support for multiple nicknames on same channel. [n] is
2484 added locally to the nickname if there are more than one same
2485 nicknames on the channel.
2487 * Server now sends all nicknames that matched WHOIS request.
2488 Client also shows the list received from server.
2490 * Added TOPIC command to client side. User can now set and show
2491 current topic on channel.
2493 * Added MOTD command to client and server. Also, server sends the
2494 motd when client connects to the server.
2496 * Changed version strings to comply ISO 8601.
2498 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Fixed protocol error handling in client library. It should now
2501 cope even if the SKE fails for some reason.
2503 * Made new protocol specification drafts for submitting to IETF.
2505 * Implemented TOPIC command to server in silcd/command.c.
2507 * Added two new notify types into lib/silccore/silcnotify.h:
2508 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2509 notify nickname change and topic setting/change on a channel.
2511 * API change of command_reply operation in client library. The
2512 application gets now the status type received from server as well.
2514 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2518 * Cras fixed and optimized the packet handling even further and
2519 it should work now. Minor change to the prototype of function
2520 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2522 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Added new function into lib/silcutil/silcschedule.[ch]:
2525 silc_schedule_with_fd to select() a specified fd. The function
2526 returns after timeout expires or data arrives or goes. The
2527 function is used by packet routines to wait that all data is
2528 received from network.
2530 * Fixed data reading from network in lib/silccore/silcpacket.c.
2531 The code now assures that all data is read from the fd and then
2532 continues packet processing. This was a bug fix since the code
2533 used to drop some data in some circumstances.
2535 * Added new function into lib/silcclient/client.[ch]:
2536 silc_client_start_key_exchange to start key exchange after
2537 connection has been established to server. The code internally
2538 now uses this funtion but its main purpose was to provide it
2539 for applications that perform their own connecting. After
2540 application has created a connection it merely calls this
2541 function to start the key exchange between client and server.
2542 The library takes care of everything else after that.
2544 Updated also lib/silcclient/README to explain the usage of
2547 * Do not send to application information that connection has
2548 been established. Application gets notified it by connect
2551 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2553 * Applied cras's patch to add silc_schedule_one function. The
2554 function runs scheduler once and returns.
2556 * Fixed the scheduler after cras messed it up. The timeout
2557 handling works now as it's supposed to work.
2559 * Added into lib/silccore/ silcnotify.h to include notify
2560 message types support. Changed silc_server_send_notify*
2561 functions, in server.[ch], to support those new notify types.
2562 Added the support for the notify types into client library,
2563 as well. Added new notify client operation into ops.h in
2566 * Changed silc_server_packet_send_to_channel to send normal
2567 packets instead of just channel message packets. The function
2568 is now used to send the notify packets to channels. It is not
2569 used to send channel message packets anymore, as server never
2572 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2573 va_arg()s as it seems to require it nowadays. I guess, if SILC
2574 is compiled with older va_arg() the new code should work anyway.
2576 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Splitted core library. Core library (lib/silccore) includes
2579 now only SILC protocol specific core (and common) components.
2580 Created new utility library (lib/silcutil) that includes more
2581 generic purpose stuff. The stuff for util library was taken
2582 from the old core library. This was minor and easy split.
2584 * Created SILC Client Library (lib/silcclient) that includes
2585 implementation of the SILC client without user interface. This
2586 was major move from silc/ directory. The code has been changed
2587 so that it is transparent towards the user interface. The
2588 silc/ directory includes now the same user interface as before
2589 and it uses the new client library. Read lib/silcclient/README.
2590 Basicly, the client library performs everything else related
2591 to SILC except user interface handling. Also, configuration
2592 files are considered to be part of user interface and library
2593 does not handle them.
2595 This change also changed a lot of structures, function naming etc.
2596 Most important change was that SilcClientWindow object was
2597 renamed to SilcClientConnection in the client library. Created
2598 also new file lib/silcclient/ops.h. Also added new files
2599 silc/local_command.[ch] and silc/client_ops.[ch].
2601 All these changes were made to make it easier for user interface
2602 designers to create what ever user interface for the SILC client
2605 It is also expected that the server will be moved to lib
2606 directory as well and SILC Server Library will be created;
2607 sometimes in the future.
2609 * Removed Local commands from lib/silccore/silccommand.h as
2610 they are application specific and new client library does not
2611 handle any of those anymore.
2613 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2614 old client implementation in silc/.
2616 * Added support for callback functions in SILC_LOG_* macros.
2617 Application can now set its own callbacks that will be called
2618 instead of using the default functions that will always print
2619 the debug messages to stderr (or stdout). Also, debugging can
2620 now be disabled by setting silc_debug to FALSE and re-enabled by
2621 setting it to TRUE. Note, that logging will still work even
2622 if debugging is disabled.
2624 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2625 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2626 silc_log_reset_debug_callbacks.
2628 * To enable debugging in silc client one must give now -d
2629 option on command line.
2631 * Changed silc_schedule_init to automatically allocate task queues
2632 if they are not allocated before calling it.
2634 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added GMP 3.1 into math library.
2638 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2641 a channel in SILC network. The packet is used by servers and
2642 routers to notify other routers that user has left a channel.
2643 This little feature was missing until now. Added the feature
2644 to protocol specification as well.
2646 Added functions: silc_server_send_remove_channel_user and
2647 silc_server_remove_channel_user into server.[ch].
2649 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2650 lib/silccore/silcpacket.h. However, they are not implemented
2653 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Fixed joining to a channel and sending channel messages
2656 between server and router. The channel message sending should
2657 now work inside a cell.
2659 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Fixed the private message sending between server and router.
2662 The private message sending should now work inside a cell.
2664 * Added silc_server_replace_id into server.[ch] to replace
2665 existing ID in the SILC network.
2667 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2668 and silc_idlist_replace_server_id into idlist.[ch] in server.
2670 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Fixed the server to server connections. Server can again now
2673 connect to router. Router to router connections probably does
2676 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Added dynamic protocol registering support. Now protocols can
2679 registered and unregistered on the fly. Patch by cras.
2681 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added lib/contrib directory to hold routines that some platforms
2684 don't have but are needed by SILC.
2686 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2687 into lin/contrib to provide getopt() and getopt_long() for
2688 those who don't have it.
2690 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added AWAY command to client. When away message is set and
2693 client receives a private message packet the client automatically
2694 replies to the sender with the away message.
2696 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2697 bug seemed to be the cause of recent problems when compiling
2700 * Added version detection support to SKE protocol specification
2701 and added the new changes to the SKE implementation as well.
2702 There were other minor changes in the SKE protocol as well.
2704 Many changes in lib/silcske/silcske.[ch] and in
2705 lib/silcske/payload.[ch].
2707 * Added ^U functionality, clear input line. Patch from cras.
2709 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Mainly small bugfixes on core library. Fixed some debugging
2712 logging and buffer overflow in silclog.c.
2714 * Updated config.sub and config.guess on the distribution tree.
2716 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2718 * Added command lagging support in server. Client may execute
2719 commands now only once in two seconds.
2721 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Optimized packet reception. MAC computation and checking is now
2724 also more optimized. A lot previously duplicated code is now
2725 used as generic by both client and server.
2727 * Fixed key pair generation in clientutil.c
2729 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Added into lib/silccore/silcbufutil.[ch] new function;
2732 silc_buffer_realloc.
2734 * Moved generic packet sending/encryption functions to
2735 lib/silccore/silcpacket.[ch] from client and server. Some
2736 rewriting of the functions.
2738 * Moved all generic packet reception/decryption functions to
2739 lib/silccore/silcpacket.[ch] from client and server. The
2740 packet processing is now much cleaner in both client and server.
2741 These were major changes in both client and server.
2743 * Created many common functions in server to do packet sending.
2744 Previously code were duplicated a lot, this has been removed
2747 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Rewrote major parts of the ID cache system. Don't know
2750 whether it is better now or not but at least the API is more
2753 * Major rewrite on ID cache stuff on client because of the ID
2754 cache API changes. Added idlist.c to client.
2756 * Also major rewrite on ID cache stuff on server as well.
2757 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2758 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2759 in hand, instead they are all put into the ID cache system now.
2760 All server_idlist_* routines uses ID cache now instead of
2761 traversing its own lists (those lists does not exist anymore).
2762 SilcIDList though still exists. Also, SilcXXXEntry's are
2765 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Finally made the SKE implementation compliant to the protocol
2768 specification. All mp integers are now binary encoded as
2769 opposed being HEX encoded.
2771 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2774 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2775 functions: silc_[encode/decode]_pem. Also added function
2776 silc_encode_pem_file to PEM encode with newlines ('\n') for
2779 * SILC public keys are now encoded either PEM or binary. Same
2780 option is for private keys as well. By default private keys
2781 are binary encoded and public keys PEM encoded. Silly HEX
2782 encoding were removed.
2784 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2785 function to create fingerprints.
2787 * Fixed a bug in SHA1; does not change the original data anymore.
2789 * Partly implemented INFO command on client and server side.
2790 Fixed CLEAR command. Changes to SERVER command; show current
2791 server(s) when giving command without arguments. Added
2792 VERSION command to client.
2794 * Added check to server that unregistered connections cannot
2795 execute commands (unless it is specificly allowed).
2797 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Fixed screen refresh.
2801 * Fixed channel joining bug from client. On some circumstances
2802 client tried to join to a channel it had already joined.
2804 * Added public key verification process into client's protocol.c.
2805 The client now verifies the public key from user and saves
2806 it into ~./silc/serverkeys/ directory.
2808 Added into: clientutil.[ch]: silc_client_verify_server_key.
2810 * Changed SKE protocol's silc_ske_initiator_finish function
2811 to accept callback function that verifies the received public
2812 key. Removed old silc_ske_verify_public_key function.
2814 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2817 silc_pkcs_private_key[_data]_set.
2819 * Made the password and public authentication more cleaner in
2820 server's protocol.c.
2822 * Removed historic and obsolete protocol `channel_auth' from
2823 both client and server.
2825 * Removed wrong way of sending command status messages from
2826 server to client in server's command.c. The old way violated
2827 protocol specification.
2829 Changes to silccore/silccommand.[ch]: removed
2830 silc_command_encode_status_payload -> not needed anymore,
2831 changed silc_command_encode_payload_va to accept extra
2832 argument on variable argument list. The argument type must
2833 now be provided to the function. Also, added new function:
2834 silc_command_encode_reply_payload_va which is same as
2835 normal command_encode_payload_va except command status type
2836 is provided as extra argument.
2838 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added ~./silc directory handling. The directory includes the
2841 public and private keys for the client.
2843 Added silc_client_check_silc_dir, silc_client_create_identifier
2844 and silc_client_load_keys.
2846 * Implemented SILC protocol compliant public key. Added public
2847 and private key saving to and loading from files.
2849 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2850 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2851 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2852 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

2860 * Added silc_server_get_route (route.[ch]) to get connection
2861 data for the fastest route for given ID.

2864 were re-defined in the SILC Protocol Specification and the
2865 implementation now complies with the specification.
2867 * Implemented PING command on client and server.
2869 * Implemented NAMES command on client and server. The server side

2883 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
