3 * Made the key generation options to the silcd program. Added
4 -C option, equivalent to client's option.
6 * Added new [ServerKeys] config section to the server. It
7 configures the server's public and private key.
9 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Made preliminary `make install' work.
13 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Added SilcServerRekey context into silcd/idlist.h.
17 * Added the PFS support as defined in the specification to the
18 SKE protocol. Affected files lib/silcske/*.c.

21 the number of the SKE group that is used with PFS in re-key.
22 Affected file silcd/idlist.h.
24 * Added PFS re-key support to the server. Affected file is
27 * Added silc_protocol_cancel to cancel execution of the next
28 state of the protocol. Affected file is
29 lib/silccore/silcprotocol.[ch].
31 * Added the re-key support with and without PFS to the client
32 library. Re-key is performed once in an hour, by default.
34 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
35 Added silc_client_rekey_callback and silc_client_rekey_final.
36 Affected files are lib/silcclient/protocol.[ch] and
37 lib/silcclient/client.[ch].
39 * Removed the `hmac_key' and `hmac_key_len' fields from the
40 SilcClientConnection structure; not needed. Affected file is
41 lib/silcclient/client.h.
45 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * Do not ask whether user wants to use the negotiated private key
48 for private messages, just use it. Affected file is
51 * Added `send_enc_key' and `enc_key_len' fields to the
52 SilcIDListData structure since they are needed in the re-key
53 phase. Affected file is silcd/idlist.[ch].
55 * Implemented the simple re-key protocol into the server.
56 Affected files silcd/server.c and silcd/protocol.[ch]. The
57 re-key will be performed once in an hour, by default.
59 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
60 Added silc_server_rekey, silc_server_rekey_callback and
61 silc_server_rekey_final.
63 * Removed Tunneled flag from the protocol. Updated the code
64 and the specifications.
66 * Adde `pfs' field to the SilcIDListData to indicate whether
67 the PFS is to be performed in the re-key. Affected file is
70 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
73 int64 of at least the xintXX size. If void * is less that 4
74 bytes uint32 * will be used. Defined bool as boolean.
76 * Changed _ALL_ unsigned long and unsigned int to uint32,
77 unsgined short to uint16 in the source tree.
79 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
80 not handle clients that has entry->data.registered == FALSE.
81 They are not in the network anymore. Affected file is
84 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Implemented the sending of the SERVER_SIGNOFF notify in the
87 server. Affected file is silcd/server.c.
89 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
90 Added also silc_notify_payload_encode_args into the
91 lib/silccore/silcnotify.[ch].
93 * Implemented ther SERVER_SIGNOFF notify handling in the server.
94 Affected file silcd/packet_receive.c.
96 * Implemented the SERVER_SIGNOFF notify handling in the client
97 library. Affected file lib/silcclient/client_notify.c. Also,
98 implemnted the printing of the SERVER_SIGNOFF info to the
99 application. Affected file silc/client_ops.c.
101 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
102 if the deleting was successful. Affected file silcd/idlist.[ch].
104 * Added support for public key authentication in the connection
105 authentication protocol in the client library. Affected file
106 lib/silcclient/protocol.c.
108 * Changed the server's silc_idlist_get_clients_by_* interface
109 to support already allocated array so that new entries may be
110 added to pre-allocated array. Affected file silcd/idlist.[ch].
111 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
114 * All command reply functions in the server now calls the
115 pending command callback even if error occured. This way the
116 error will be delivered to the client as well. Affected files
117 silcd/command.c and silcd/command_reply.c.
119 * Fixed INFO command to return local server's info if no server
120 was provided. Affected file lib/silcclient/command.c.
122 * Removed RESTART command for good. Updated the code and the
125 * Rewrote parts of the task system. It is a bit simpler now.
126 Removed unsued task priorities. The affected files are
127 lib/silcutil/silctask.[ch].
129 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Moved the USERS printing from the library to the application.
132 Affected files lib/silcclient/command.c and silc/client_ops.c.
134 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Added channel key re-key support. The re-key is perfomed
139 only by the router and is done once in an hour. Added `rekey'
140 field to the SilcChannelEntry in the server. Affected files
141 silcd/server.c and silcd/idlist.h.
143 * Added silc_task_unregister_by_context into the file
144 lib/silcutil/silctask.[ch].
146 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Added SILC_UMODE_GONE mode to indicate when the client is not
149 present in the SILC network. Added also support to the local
150 command AWAY that will set this mode. Added support of showing
151 "xxx is gone" in WHOIS command. The USERS command shows the
154 * Fixed setting server and router operator privileges in the
155 server's UMODE command. Affected file silcd/command.c.
157 * Merged the SKE KE1 and KE2 payloads into one payload. The
158 new KE payload is equivalent to the old KE2 payload.
160 Cleaned up the SKE Start Payload parsing. It now uses the
161 simple buffer unformatting to do the parsing. A lot faster
164 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
165 to the SKE that is used to indicate whether both of the SKE
166 parties should perform authentication. By default only the
167 responder performs authentication. By setting this flag also
168 the initiator must do authentication. By default it is unset
169 since in normal SKE case, client to server connection, only
170 the responder should do authentication. When doing SKE between
171 two clients both should perform authentication. Updated the
172 code and the protocol specs.
174 * A little fix to IDENTIFY command in the server. Search the
175 client first by hash not nickname. Affected file is
178 * Fixed the silc_client_close_connection to support closing
179 the client to client connections wihtout deleting too much
180 data. Affected file lib/silcclient/client.c.
182 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
183 are received if protocol used to be active but is not anymore
184 the application would crash due to NULL pointer dereference.
185 Affected files silcd/server.c and lib/silcclient/client.c.
187 * Added `hash' field to the SilcClientConnection to include
188 the hash function negotiated in the SKE protocol.
190 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
191 to set the channel founder authentication data. A client can
192 claim the founder rights later by providing the authentication
193 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
194 This way the channel founder can regain the channel founder
195 privileges even it is left the channel. This works only on
196 local server and the client must be connected to the same
197 server to be able to regain the founder rights. Updated the
198 protocol specs accordingly.
200 Added support to the CMODE command in the client to set the
201 founder auth data. Read the README to see how to set it.
203 Added support to the CUMODE command to claim the founder
204 rights. Read the README to see how to do it.
206 Added support for the founder authentication to the Channel
207 Entry in the server. Affected file silcd/idlist.h.
209 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
210 server's CMODE command. Affected file silcd/command.c.
212 * Added the following new functions into lib/silccore/silcauth.[ch]:
213 silc_auth_get_method and silc_auth_get_data.
215 * The server now saves the remote hosts public key to the
216 SilcIDListData pointer. Affected file silcd/protocol.c.
218 * The normal server now does not remove the channel entry from
219 the cache if the founder authentication data is set. It used
220 to remove it if the founder was the last one on the channel on
221 the server and left the channel. The auth data is saved and
222 if the channel is re-joined later the old entry is used with
223 the old auth data. Affected files silcd/command_reply.c and
226 * Removed the `pkcs' field from the SilcIDListData structure
227 in the server; it is not used. Affected file silcd/idlist.h.
229 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Fixed packet processing on slow links. Partial packets were
232 never re-processed because the incoming data buffer was cleared
233 by the application. Application must not directly clear the
234 sock->inbuf, the packet processing routines handle it. Fixed
235 this in client library and in server.
237 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * Fixed the WHOIS and IDENTIFY send reply function to really
240 check whether to send list or just one entry. Affected file
243 * Cleaned up the LEAVE command's channel key distribution. The
244 affected file silcd/command.c.
246 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
247 can enforce the channel mode as well. In that case the ID
248 includes the ID of the server. The code now enforces the
249 mode change if the router have different mode than the server.
251 * The notify client operation with CMODE_CHANGE notify can now
252 return NULL client_entry pointer if the CMODE was not changed
253 by client. Application must check for this.
255 * Added <Server ID> argument to INFO command to support server
256 info fetching by Server ID.
258 * Added silc_server_announce_get_channel_users to get assembled
259 packets of channel users of the specified channel. Affected
260 file silcd/server.[ch].
262 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
263 was freed underneath the ID Cache.
265 * Re-announce clients when the server received CHANNEL_CHANGE
266 notify from the router. Affected file silcd/packet_send.c.
268 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
271 crashed since it did not handle the fact that there is no cipher
272 called "3" and didn't check the error condition. Now fixed.
274 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
275 flag. It can be used to send message requests.
277 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Implemented the RESTART command in the client.
281 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
282 notice type messages. Added notice printing to the user
285 * The channel keys are not re-generated if the channel's mode
286 is PRIVKEY, ie private key on the channel exists. Affected
287 files silcd/server.c and silcd/command.c.
289 * Fixed a little bug in channel message delivery when channel
290 private keys are set in the server. Affected file is
293 * Changed the setting on channel->on_channel = TRUE from the
294 silc_client_save_channel_key to the JOIN command reply. The
295 key payload is not received if the private channel key is set.
296 Affected file lib/silcclient/command_reply.c and the
297 lib/silcclient/client_channel.c.
299 * When the CMODE_CHANGE notify is sent and the channel private
300 key mode is removed the channel key must be re-generated in
301 other cells as well. Added this support for the router in the
302 silcd/packet_receive.c.
304 * Added new local command NOTICE to send notice message on
305 channel. Affected file silc/local_command.[ch].
307 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Added new local command ME to the client. It is used to send
310 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
311 some action. Affected file silc/local_command.[ch].
313 * Changed channel_message and private_message client operations
314 to deliver the message flags to the application. Added also
315 the `flags' arguments to the silc_client_send_channel_message
316 and silc_client_send_private_message functions. Affected file
319 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Redefined the Private Message Payload to support private message
322 keys and to support the new private message flags. Updated
323 the protocol specs. Flags makes it possible to have for example
326 * Added new type SilcPrivateMessagePayload and defined an API
327 for it in the lib/silcclient/silcprivate.[ch].
329 * Tested private message private keys successfully. Tested the
330 private message key set, unset and list commands with the new
333 * Redefined the Channel Message Payload to include the channel
334 message flags (equal with private message flags) to support
335 for example CTCP style messages.
337 * Defined some of the message (for channel and private message)
338 flags. Updated the protocol specs and added the flags to the
339 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
341 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added SilcKeyAgreementStatus type to the key agreement routines
344 to indicate the current status and error if one occured.
345 The status types are defined in the lib/silcclient/silcapi.h.
347 * Added new local command KEY that is used to set and unset private
348 keys for channels, set and unset private keys for private messages
349 with remote clients and to send key agreement requests and
350 negotiate the key agreement protocol with remote client. The
351 key agreement is supported only to negotiate private message keys,
352 it currently cannot be used to negotiate private keys for channels,
353 as it is not convenient for that purpose.
355 * Fixed a minor pending callback setting bug in the function
356 silc_client_get_client_by_id_resolve, now the function works.
357 Affected file lib/silcclient/idlist.c.
359 * Added function silc_net_get_local_port to get local bound
360 port by socket. Added to lib/silcutil/silcnet.[ch].
362 * Added `sockets' and `sockets_count' fields to the SilcClient
363 object. They hold the sockets of the listenning sockets in
364 the client. Listenning sockets may be for example the key
365 agreement server. Affected file lib/silcclient/client.[ch].
366 Added functions the silc_client_add_socket and the
367 silc_client_del_socket. They are exported to the application
370 * Added ~./silc/clientkeys to support other client's public keys.
372 * Renamed verify_server_key client operation to verify_public_key
373 and added one argument to indicate the type of the connection
374 (server, client etc.).
376 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * Added silc_server_connection_auth_request to handle the
379 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
380 silcd/packet_receive.[ch].
382 * Added silc_server_send_connection_auth_request into the
383 silcd/packet_send.c to send the connection auth request packet.
385 * Cleaned up the silcd/protocol.c a bit and fixed some memory
388 * Fixed the public key authentication in responder side in the
389 server. The `auth_data' pointer includes the SilcPublicKey
390 not the path to the public key. Affected file silcd/protocol.c.
392 * Implemented the public key authentication in the initiator side
393 in the server. Affected file silcd/protocol.c.
395 * Removed the [RedirectClient] config section from the server
396 configuration. Is not needed and I don't want to implement it.
398 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Cleaned up the CMODE command in the server. It now works
401 correctly and supports all the modes defined in the protocol.
402 Affected file is silcd/command.c.
404 * Added `hmac_name' field to the SilcChannelEntry in the server
405 to hold the default HMAC of the channel. It can be set when
406 creating the channel (with JOIN command). Affected files
409 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
410 type to indicate the change of the current cipher and hmac
411 on the channel. Client can safely ignore the <cipher> argument
412 (if it chooses to do so) since the CHANNEL_KEY packet will
413 force the channel key change anyway. The <hmac> argument is
414 important since the client is responsible of setting the new
415 HMAC and the hmac key into use.
417 * Fixed the CMODE command in the client library as well.
419 * Tested CMODE command in router environment successfully.
421 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Show the version of the remote client (or server) when connecting
424 to the server. It is logged to the log file. Affected file
427 * Fixed the KILLED notify handling in the client library. The
428 client must be removed from all channels when receiving the
431 Also, do not remove the client entry when giving the KILL
432 command but when the KILLED notify is received.
434 * Removed silc_idlist_find_client_by_nickname from the server.
435 Not needed anymore. Affected files silcd/idlist.[ch].
437 * Implemented the CHANNEL_CHANGE notify type handling to the
438 server. Affected file silcd/server.c.
442 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Added silc_server_send_notify_invite to send the INVITE
445 notify between routers.
447 * Implemented the INVITE command correctly to the server.
449 * Implemented the INVITE notify type handling in the server.
451 * Implemented the INVITE command to the client library and on the
454 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Added function silc_server_get_client_resolve to find the
457 client entry by ID from all ID lists and then resolve it
458 (using WHOIS) if it cannot be found. Affected file is
461 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Implemented the BAN command to the client library.
465 * The JOIN command in the server now checks the invite list
468 * Changed the silc_command_reply_payload_encode_va and the
469 silc_command_payload_encode_va to support that if argument is
470 NULL it ignores and checks the next argument. Affected file
471 lib/silccore/silccommand.c.
473 * Added silc_server_send_notify_ban to send the BAN notify
474 type between routers.
476 * Chaned the silc_notify_payload_encode to support that if
477 argument is NULL it ignores and checks the next argument.
478 Affected file lib/silccore/silcnotify.c.
480 * Tested ban lists in router environment successfully.
482 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Implemented BAN command to the server, in silcd/command.[ch].
486 * Removed the BAN and INVITE_LIST modes from the CMODE command
489 * Added function silc_string_match to regex match two strings.
490 Affected files lib/silcutil/silcutil.[ch].
492 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Redefined parts of the SilcChannelEntry in the server to support
495 the new ban and invite lists.
497 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Redefined the INVITE command. The same command can be used to
500 invite individuals to the channel but also to manage the invite
501 list of the channel (to add to and remove from the invite list).
502 Updated the protocol specs.
504 * Added new command SILC_COMMAND_BAN that can be used to manage
505 the ban list of the channel. Updated the protocol specs.
507 * Removed the channel modes: the SILC_CMODE_BAN and the
508 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
509 in the CMODE command. The equivalent features are now available
510 using INVITE and BAN commands. Updated the protocol specs.
512 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
513 in the network about change in the current ban list. The notify
514 type is not used by the client.
516 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
517 support the invite lists.
519 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Added new function silc_string_regexify that converts string
522 including wildcard characters into regex string that can
523 be used by the GNU regex library. Added into the file
524 lib/silcutil/silcutil.[ch].
526 Added silc_string_regex_combine to combine to regex strings
527 into one so that they can be used as one regex string by
528 the GNU regex library. Added into the file
529 lib/silcutil/silcutil.[ch].
531 Added silc_string_regex_match to match two strings. It returns
532 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
534 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Imported GNU regex to the soruce tree into lib/contrib.
537 Fixed some compiler warning from the regex.c.
539 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Fixed MOTD command in the server to work in router environment.
543 * Fixed the MOTD command in the client library to support
544 the server argument in the command.
546 * Added `nickname_len' argument to the silc_idlist_add_client
547 in the server, as the `nickname' argument may be binary data
550 * Added silc_idlist_get_channels to return all channels from
553 * Implemented LIST command to the server. Affected file is
556 * Implemented the LIST command to the client library and on the
559 * Added [<user count>] argument to the LIST command reply.
560 With private channels the user count is not shown.
562 * Updated TODO and README.
564 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * The client entry's data.registered must be TRUE even with
567 global client entry on global client list. The data.registered
568 is used to check whether the client is anymore in the network,
569 for example with WHOWAS command so it must be valid.
571 * Fixed the WHOWAS command in the server. It now actually works
572 in router environment. Added function into silcd/command_reply.c
573 silc_server_command_reply_whowas_save.
575 * Added silc_idlist_purge function to the silcd/idlist.c
576 to periodically purge the ID Cache.
578 * Fixed INFO command in the server. It works now in router
579 environment. Added <server name> argument to the INFO command
580 reply. Updated the protocol specs.
582 * Fixed minor bug in silc_idcache_purge to not purge if the
583 expire value is zero.
585 * Fixed various bugs in WHOIS and IDENTIFY command handling as
586 they were buggy because of the WHOWAS information.
588 * Fixed local command MSG to handle the async resolving of
589 the remote client properly. It used to fail the first MSG.
590 Affected file silc/local_command.c.
592 * Added `data_len' field to SilcIDCache context.
594 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Update TODO. Todo in commands in the server.
598 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
601 used by routers as broadcast packet to inform other routers
602 about the changed user mode.
604 Implemented the notify handling in the server. Affected file is
605 silcd/packet_receive.c. Added the function
606 silc_server_send_notify_umode to the silcd/packet_send.[ch].
608 * Added new generic Channel Payload and deprecated the New Channel
609 Payload. The New Channel Payload is now the generic Channel
612 * Added new argument `mode' to the silc_server_send_new_channel
613 as it is required in the Channel Payload now.
615 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
616 and created a new and real SilChannelPayload to represent the
617 new generic Channel Payload. Implemented the encode/decode
618 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
620 * Added silc_server_get_client_channel_list to return the list
621 of channels the client has joined for WHOIS command reply.
622 Affected file silcd/server.[ch].
624 * Implemented the channel list sending in the WHOIS command reply
625 in server and in the client.
627 Implemented the channel list displaying on the user interface
628 as well. Affected file silc/client_ops.c.
630 * Added silc_channel_payload_parse_list to parse list of Channel
631 Payloads. It returns SilcDList list of SilcChannelPayloads.
632 Client for example can use this function to parse the list of
633 channels it receives in the WHOIS command reply. The caller
634 must free the list by calling silc_channel_payload_list_free.
635 Affected files lib/silccore/silcchannel.[ch].
637 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Added one new argument <user mode> to the WHOIS command reply
640 to return the mode of the user in SILC. Updated the protocol
643 Implemented it to the server and client.
645 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Fixed the mode printing on the user interface on joining.
648 Affected file silc/client_ops.c.
650 * Implemented the UMODE command and user modes in general to the
651 client library and to the user interface.
653 * Implemented the UMODE command to the server.
655 * The server now sends UNKNOWN_COMMAND error status if client sends
656 unknown command. Affected file silcd/command.c.
658 * All server commands now handle the command identifier the right
659 way when sending the command reply to the client. The client can
660 use to identify the command replies with the identifier.
662 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Added silc_server_get_client_route to resolve the route to
665 the client indicated by the client ID. Affected file is
668 * Added silc_server_relay_packet as general function to relay
669 packet to arbitrary destination. This deprecates functions
670 like _send_private_message_key, _relay_notify etc. Affected
671 file is silcd/packet_send.[ch].
673 Removed silc_server_send_key_agreement,
674 silc_server_send_private_message_key and
675 silc_server_packet_relay_notify functions from the file
676 silcd/packet_send.[ch].
680 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
681 server. Affected file silcd/packet_receive.[ch].
683 * Implemented the KILL command to the client. Implemented the
684 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
685 Affected files lib/silcclient/command[_reply].c and
686 lib/silcclient/client_notify.c. Implemented the KILL notify
687 printing in the user inteface.
689 * Fixed a lot silc_parse_nick memory leaks from the client
690 library in the file lib/silcclient/command.c.
692 * Changed the silc_server_send_notify_on_channels's `sender'
693 argument from SilcSocketConnection to SilcClientEntry to
694 check the sender as entry and not as connection object and not
695 to send to the client provided as argument. The affected file
696 is silcd/packet_send.[ch].
698 * The notify packets that are destined directly to the client used
699 to not to be processed by the server. Now changed that and the
700 server processes all notify packets. After relaying the packet
701 to the client the notify packet is processed in the server.
703 * The silc_server_free_client_data now checks whether there is
704 pending outgoing traffic for the client and purges the data to
705 the network before removing the client entry.
707 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
710 an client is killed from the SILC Network. Updated the protocol
713 Added new function silc_server_send_notify_killed to the
714 silcd/packet_send.[ch].
716 * Added function silc_server_packet_relay_notify to relay notify
717 packets that are destined directly to a client. In this case
718 the server does not process the notify packets but merely relays
719 it to the client. Affected file silcd/packet_send.[ch].
721 Added also silc_server_packet_process_relay_notify to check
722 whereto relay the notify. Affected file is
723 silcd/packet_receive.[ch].
725 * Implemented the KILL command to the server.
729 * Added the backup schema desgined last fall to the protocol
730 specs for everyone to see. The specification is in the
731 *-spec-xx.txt draft and the packet type definitions for the
732 backup routers is in *-pp-xx.txt draft. Thusly, added also
733 new packet type SILC_PACKET_CELL_ROUTERS.
735 * A big security problem in the implementation discovered. The
736 signoff of an client did not cause new channel key generation
737 which it of course should've done. The channel keys must be
738 always re-generated when client leaves (or signoffs) the channel.
739 The silc_server_remove_from_channels funtion now handles
740 the channel key re-generation.
742 * Added `sender' argument to the silc_server_send_notify_on_channels
743 to not to send the client provided as argument. Affected file
744 silcd/packet_send.[ch].
746 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Implemented OPER and SILCOPER commands into the server and
751 * Added silc_auth_verify and silc_auth_verify_data to verify
752 the authentication directly from the authentication payload.
753 It supports verifying both passphrase and public key based
754 authentication. Affected file lib/silccore/silcauth.[ch].
756 * Added `hash' field to the SilcIDListData structure. It is the
757 hash negotiated in the SKE protocol. Affected file is
760 * Slight redesigning of the SilcAuthPayload handling routines.
761 Do not send SilcPKCS but SilcPublicKey as argument.
763 * Implemented the public key authentication support to the
764 serverconfig. The public key is loaded from the provided path
765 and saved as authentication data to void * pointer. Thus,
766 changed the unsigned char *auth_data to void *auth_data;
768 * Fixed SHUTDOWN command to send the reply before the server
769 is shutdown. :) Affected file silcd/command.c.
771 * Fixed fatal bug in CONNECT command. The hostname was invalid
772 memory and server crashed. Affected file silcd/command.c.
774 * Fixed fatal bug in CLOSE command. The server_entry became
775 invalid but was referenced later in the command. Affected file
778 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Fixed fatal bug in failure packet handling. Server ignored
781 the failure and thus crashed when it came.
785 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
788 that the command may be executed only once in (about) 2 seconds.
789 The old SILC_CF_LAG flag is same but allows command bursts up
790 to five before limiting.
792 Added the support for CF_LAG and CF_LAG_STRICT flags to the
793 server code. Various commands now includes the CF_LAG_STRICT
794 flag to disallow any kind of miss-use of the command.
796 * Fixed the silc_buffer_unformat to not to allocate any data
797 if the length of the data is zero. It used to allocate the
798 length + 1. Affected file lib/silcutil/silcbuffmt.c.
800 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Changed the format of AdminConnection configuration section
803 in the server. Added username of the admin to the format.
804 Affected files silcd/serverconfig.[ch].
806 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
807 to return admin configuration data by host, username and/or
810 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Implemented WHOWAS command to the server. Added the functions:
814 silc_server_command_whowas_parse,
815 silc_server_command_whowas_send_reply,
816 silc_server_command_whowas_from_client and
817 silc_server_command_whowas_from_server
819 * Added <Client ID> argument to the WHOWAS command reply. Updated
820 the protocol specs accordingly.
822 * Implemented WHOWAS command and command_reply to the client
825 Implemented the WHOWAS printing on the user interface.
827 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added new argument to the WHOWAS command reply, the real name.
830 It is an optional argument. Updated the protocol specs.
832 * Added SilcIDCacheDestructor callback that is registered when
833 the SilcIDCache is allocated. The callback is called when
834 an cache entry in the ID Cache expires, or is purged from the
835 cache. Added into lib/silccore/idcache.[ch].
837 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
838 to destruct the client entries when the cache entry expires.
839 Other ID Cache's in server and in the client library ignores
842 * If the ID Cache entry's `expire' field is zero then the entry
843 never expires. Added boolean `expire' argument to the
844 silc_idcache_add function in the lib/silccore/idcache.[ch].
845 If it is TRUE the default expiry value is used.
847 * Added silc_server_free_client_data_timeout that is registered
848 when client disconnects. By default for 5 minutes we preserve
849 the client entry for history - for WHOWAS command.
851 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added support to the server to enforce that commands are not
854 executed more than once in 2 seconds. If server receives
855 commands from client more frequently, timeout is registered
856 to process the commands. Affected file silcd/command.c.
857 Added new function silc_server_command_process_timeout.
859 * Changed NICK_NOTIFY handling in client library to check that
860 if the client's nickname was changed, so there is no need to
861 resolve anything from the server.
863 * Removed error printing from the WHOIS and IDENTIFY commands.
864 If error occurs then it is ignored silently in the client library.
865 The application, however, may map the received error to
866 human readable error string. The application currently maps
867 the NO_SUCH_NICKNAME error to string.
869 * Made the command status message public to the application. Moved
870 them from lib/silcclient/command_reply.c to
871 lib/silcclient/command_reply.h. The application can map the
872 received command status to the string with the
873 silc_client_command_status_message function.
875 * Added check to the server to check that client's ID is same
876 as the Source ID in the packet the client sent. They must
879 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Added dist-bzip hook to the Makefile.am to make bzip2
882 compressed distributions.
884 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Server now enforces the maximum length for the nickname and
887 the channel as protocol specification dictates. 128 bytes for
888 nickname and 256 bytes for channel name.
890 * Moved the WHOIS printing to the application. The client libary
891 does not print out the WHOIS information anymore, the application
892 must do it. Renamed silc_client_command_reply_whois_print to
893 the silc_client_command_reply_whois_save.
895 The client's idle time is also sent to the application now, and
896 the idle is shown on screen.
898 * Added silc_client_command_reply_identify_save to save the
899 received IDENTIFY entries.
901 * Do not check for channel private keys in message sending and
902 reception if the channel does not have the PRIVKEY mode set.
903 Affected file lib/silclient/client_channel.c.
905 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
908 just surfaced after chaning the JOIN procedure.
910 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Added silc_client_get_clients_by_list to get client entries
913 from Client ID list, that is returned for example by JOIN
914 and USERS command replies. The application should use this
915 function for example when JOIN command reply is received to
916 resolve the clients already on the channel (library does not
917 do that anymore as USERS command reply is not used in the JOIN
918 procedure anymore). Affected files lib/silcclient/silcapi.h and
919 lib/silcclient/idlist.c.
921 * JOIN command reply and USERS command reply returns now SilcBuffer
922 pointers instead of unsigned char pointers when returning
923 the client list and mode list.
925 * Added <Client ID> argument to the JOIN command reply, mainly
926 for the server to identify for which client the command was
927 originally sent. Updated protocol specs accordingly.
929 * Added SilcDlist private_key pointer to the SilcChannelEntry
930 in the client to support the channel private keys. Affected
931 file is lib/silcclient/idlist.h.
933 * Added SilcChannelPrivateKey argument to the function
934 silc_client_send_channel_message so that application can choose
935 to use specific private ke if it wants to. If it is not provided,
936 the normal channel key is used, unless private keys are set.
937 In this case the first (key that was added first) is used
938 as the encryption key.
940 * Implemented the support for channel private key handling.
941 Implemented the following functions:
943 silc_client_add_channel_private_key,
944 silc_client_del_channel_private_keys,
945 silc_client_del_channel_private_key,
946 silc_client_list_channel_private_keys and
947 silc_client_free_channel_private_keys
949 Affected file lib/silcclient/client_channel.c.
951 * Added the support for the private keys in the channel message
952 sending and encryption and in the message reception and
953 decryption. Affected funtions are
954 silc_client_send_channel_message and silc_client_channel_message.
956 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Added SKE's key verify callback to the client library's
959 KE protocol context. Affected files lib/silcclient/protocol.[ch].
961 * Removed the statement that server (or router) must send USERS
962 command reply when joining to the channel so that the client
963 knows who are on the channel. Instead, the client list and
964 client's mode list is now sent in the JOIN command reply to the
965 client who joined channel. This is better solution.
967 * Added function silc_server_get_users_on_channel and function
968 silc_server_save_users_on_channel to the silcd/server.[ch].
970 * Removed function silc_server_command_send_users from the
973 * Do not show topic on the client library anymore. The topic is
974 sent in the command reply notify to the application and the
975 application must show the topic now.
977 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Added client searching by nickname hash into the IDENTIFY and
980 WHOIS commands in the server as they were clearly missing from
981 them. Affected file is silcd/command.c.
983 * Fixed a bug in private message receiving in the client library.
984 The remote ID was freed and it wasn't supposed, now it is
987 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Minor fix to the channel payload; allocate the data area, as it
990 needs to be of specific length.
992 * If the key agreement port is zero then the operating
993 system will define the bound port. Affected files are
994 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
996 * Added new function silc_channel_payload_decrypt into the file
997 lib/silccore/silcchannel.[ch].
999 * Moved the channel message etc, check from silc_packet_decrypt
1000 to applications. The library calls now a generic
1001 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1002 when the packet is either normal or special. This was done to
1003 allow more wide range of checking that was not allowed when
1004 the code was in library. Now applications can do virtually any
1005 checks to the packet and return to the library the decision how
1006 the packet should be processed. Affected files are
1007 lib/silccore/silcpacket.[ch].
1009 Added silc_server_packet_decrypt_check to the server and
1010 silc_client_packet_decrypt_check to the client library.
1012 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1013 to send with specified source and destination information.
1015 * Channel message delivery between routers was broken after the
1016 channel key distribution was fixed earlier. The channel key
1017 was used be to distributed to other routers as well which is not
1018 allowed by the protocol. Now this is fixed and channel keys
1019 really are cell specific and the channel message delivery between
1020 routers comply with the protocol specification.
1022 * Fixed various commands in server to check also the global list
1023 for the channel entry and not just the local list. The affected
1024 file silcd/command.c.
1026 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Added assert()s to buffer formatting and unformatting routines
1029 to assert (if --enable-debug) when error occurs. Affected
1030 file: lib/silcutil/silcbuffmt.c.
1032 * Changed to auto-reconnect to check whether the remote host is
1033 router and register the re-connect timeout if it is. It used
1034 to check that whether we are normal server, but router must do
1035 auto-reconnect with another router as well. Affected file
1038 * Removed the [<key len>] option from CMODE command as the cipher
1039 name decides the key length, nowadays. See the defined ciphers
1040 from the protocol specification.
1042 * Added [<hmac>] option to the CMODE command to define the HMAC
1043 for the channel. Added SILC_CMODE_HMAC channel mode.
1045 * Added [<hmac>] option for the JOIN command so that user can
1046 select which HMAC is used to compute the MACs of the channel
1049 * Added Hmac field to the Channel Message Payload. The integrity
1050 of plaintext channel messages are now protected by computing
1051 MAC of the message and attaching the MAC to the payload. The
1052 MAC is encrypted. Now, it is clear that this causes some
1053 overhead to the size of the packet but rationale for this is that
1054 now the receiver can verify whether the channel message decrypted
1055 correctly and also when private keys are set for the channel the
1056 receiver can decrypt the packet with several keys and check from
1057 the MAC which key decrypted the message correctly.
1059 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1060 lib/silccrypt/silccipher.[ch].
1062 * Added silc_hash_len to return the digest length into the
1063 lib/silcrypt/silchash.[ch].
1065 * Rewrote parts of Silc Channel Payload interface in the
1066 lib/silccore/silcchannel.[ch]. The encode function now also
1067 encrypts the packet and parse function decrypts it.
1069 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Fixed a minor formatting bug in the SKE's key material processing.
1072 It actually might have processed the keys wrong way resulting
1075 * Redefined the mandatory HMAC algorithms and added new algorithms.
1076 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1077 and hmac-md5 truncated to 96 bits. The mandatory is now
1078 hmac-sha1-96. Rest are optional (including the one that used
1079 to be mandatory). Rationale for this is that the truncated HMAC
1080 length is sufficient from security point of view and can actually
1081 make the attack against the HMAC harder. Also, the truncated
1082 HMAC causes less overhead to the packets. See the RFC2104 for
1085 * Added new [hmac] configuration section. The SKE used to use
1086 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1087 is of course wrong. The official names that must be proposed in
1088 the SKE are the ones defined in the protocol specification
1089 (hmac-sha1-96 for example). The user can configure any hmac
1090 using any hash function configured in the [hash] section. At
1091 least, the mandatory must be configured.
1093 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1095 * Added HMAC list to the SKE proposal list. It has now both
1096 hash algorithm list and HMAC list. This makes the protocol
1097 incompatible with previous versions. The SKE now seems to work
1098 the way it is supposed to work, for the first time actually.
1100 * Defined plain Hash algorithms to the protocol specification.
1103 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Implemented support for key agreement packets into the server.
1106 Added functions silc_server_key_agreement and
1107 silc_server_send_key_agreement. Other than these functions,
1108 server has nothing to do with this packet.
1110 * Added support for private message key packets into the server.
1111 Added functions silc_server_private_message_key and
1112 silc_server_send_private_message_key.
1116 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1117 called in the protocol's final callback instead in the END
1118 protocol state. This makes a little more sense and in the same
1119 time in client we can use the same protocol routines for normal
1120 key exchange and to key agreement packet handling as well.
1122 * Added to both client's and server's KE protocol context the
1123 SilcSKEKeyMaterial pointer to save the key material. We will
1124 bring the key material to the protocol's final callback by doing
1125 this. The final callback must free the key material.
1127 * Added SKE's packet_send callback into client's KE protocol
1128 context so that the caller can choose what packet sending function
1129 is used. This way we can use different packet sending when
1130 doing normal SKE when doing key agreement packet handling (in
1131 the key agreement packet handling we do not want to encrypt
1134 * Implemented the responder side of the key agreement routines
1135 in the client. The client can now bind to specified port and
1136 accept incoming key negotiation. The key material is passed
1137 to the application after the protocol is over.
1139 * Implemented the processing of incoming Key Agreement packet
1140 in the client. Added function silc_client_key_agreement to
1143 * Implemented the intiator side of the key agreement routines
1144 in the client. The client can now initiate key agreement with
1145 another remote client. The key material is passed to the
1146 application after the protocol is over.
1148 * Created client_keyagr.c to include all the key agreement
1151 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1152 SILC_TASK_CALLBACK except that it is not static.
1154 * Created client_notify.c and moved the Notify packet handling
1155 from the client.[ch] into that file.
1157 * Created client_prvmsg.c and moved all private message and
1158 private message key routines from the client.[ch] into that file.
1160 * Create client_channel.c and moved all channel message and
1161 channel private key routines from the client.[ch] into that file.
1163 * Changed silc_client_get_client_by_id_resolve to resolve with
1164 WHOIS command instead of IDENTIFY command, in the file
1165 lib/silclient/idlist.c.
1167 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Implemented the SKE's responder side to the Client library.
1171 * When FAILURE is received to the protocol do not trust it
1172 blindly. Register a timeout to wait whether the remote closes
1173 the connection as it should do it, only after that process the
1174 actual failure. This was changed to both client and server.
1176 * Added client_internal.h to include some of the structures
1177 there instead of client.h in lib/silcclient/.
1179 * Added function silc_task_unregister_by_callback to unregister
1180 timeouts by the callback function.
1182 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Some "Incomplete WHOIS info" errors has been appearing on the
1185 log files. Took away the entry->userinfo check from WHOIS
1186 reply sending. The entry->userinfo is now " " if client did not
1187 provide one. I thought this was fixed earlier but something
1188 is wrong still. Let's see if the error still appears.
1190 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Fixed a minor bug in the login when the channel key is
1193 re-generated in the server. It used to generate the key in
1194 wrong order and thus caused problems in the channel traffic.
1196 * Fixed a minor bug in channel key distsribution after
1197 KICK command. The key was not sent to the router even though
1200 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Added silc_ske_process_key_material_data as generic routine
1203 to process any key material as the SILC protocol dictates. The
1204 function is used by the actual SKE library but can be used by
1205 applications as well. This relates to the private message keys
1206 and the channel private keys since they must be processed the
1207 same way the normal SILC session keys. The protocol dictates
1208 this. Affected files: lib/silcske/silcske.[ch].
1210 Added also silc_ske_free_key_material to free the
1211 SilcSKEKeyMaterial structure.
1213 * Defined silc_cipher_set_key function to set the key for
1214 cipher without using the object's method function. The affected
1215 files: lib/silccrypt/silccipher.[ch].
1217 * Implemented silc silc_client_add_private_message_key,
1218 silc_client_add_private_message_key_ske,
1219 silc_client_del_private_message_key,
1220 silc_client_list_private_message_keys and
1221 silc_client_free_private_message_keys functions in the
1224 Added functions silc_client_send_private_message_key to send
1225 the Private Message Key payload and silc_client_private_message_key
1226 to handle incoming Private Message Key payload.
1228 * Added Cipher field to the Private Message Key payload to set
1229 the cipher to be used. If ignored, the default cipher defined
1230 in the SILC protocol (aes-256-cbc) is used.
1232 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Removed lib/silcclient/ops.h file.
1236 Redefined parts of the SILC Client Library API. Created new
1237 file silcapi.h that deprecates the ops.h file and defines the
1238 published Client Library API. Defined also private message key
1239 API and channel private key API into the file.
1241 This is the file that the application must include from the
1242 SILC Client Library. Other files need not be included by
1243 the application anymore.
1245 * Added new key_agreement client operation callback and also
1246 defined the Key Agreement library API for the application.
1248 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1251 is used by clients to request key negotiation between another
1252 client in the SILC network. If the negotiation is started it
1253 is performed using the SKE protocol. The result of the
1254 negotiation, the secret key material, can be used for example
1255 as private message key.
1257 Implemented the Key Agreement payload into the files
1258 lib/silccore/silauth.[ch].
1260 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Redefined ciphers for the SILC protocol. Added some new ciphers
1263 and defined the key lengths for the algorithms. Changed the
1264 code accordingly. The default key length is now 256 bits.
1266 * Fixed SKE key distribution function silc_ske_process_key_material
1267 when the key length is more than 128 bits. The default key
1268 length in SILC is now 256 bits.
1270 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1271 to indicate unsupported algorithm.
1273 * Renamed rijndael.c to aes.c and all functions as well.
1275 * Fixed a long standing channel key setting bug in client library.
1276 Weird that it has never surfaced before.
1278 * Fixed bug in channel deletion. If the entire channel is removed
1279 then it must also delete the references of the channel entry
1280 from the client's channel list as the client's channel entry and
1281 the channel's client entry share same memory.
1283 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Implemented CONNECT and SHUTDOWN commands in the client.
1287 * Implemented CLOSE command to the client.
1289 * Added the function silc_idlist_find_server_by_name into the
1290 files silcd/idlist.[ch].
1292 Added the function silc_idlist_find_server_by_conn into the
1293 files silcd/idlist.[ch].
1295 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1297 * DIE command was renamed to SHUTDOWN. Updated the both code
1300 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1301 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1303 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1306 * Added function silc_server_create_connection function to create
1307 connection to remote router. My server implementation actually
1308 does not allow router to connect to normal server (it expects
1309 that normal server always initiates the connection to the router)
1310 so the CONNECT command is only good for connecting to another
1313 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1316 or some other client was kicked from the channel.
1318 Implemented the handling of the notify type to both client
1321 Implemented silc_server_send_notify_kicked to send the KICKED
1322 notify. It is used to send it to the server's primary router.
1324 * Implemented the KICK command into server and client.
1326 * Added `query' argument to the silc_idlist_get_client function
1327 to indicate whether to query the client from server or not if
1330 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1331 to indicate that the client is not channel founder.
1335 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Removed the rng context from SilcPacketContext structure and
1338 changed that the packet routine uses the Global RNG API.
1340 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added support for quit message that client can "leave" on the
1343 channel when it quits the SILC. It is ditributed inside the
1344 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1346 Added silc_server_free_client_data that will take the
1347 signoff message as argument.
1349 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1351 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Updated parts of the protocol specification to keep it up
1356 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1359 payloads in one packet.
1361 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1362 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1363 use now the new List flag.
1365 * Also deprecated the following packet types: REPLACE_ID,
1366 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1368 * Added list support for Notify packet in server.
1370 * Added silc_server_send_notify_channel_change to send the
1371 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1372 the silc_server_send_replace_id.
1374 * Added silc_server_send_notify_nick_change to send the
1375 NICK_CHANGE notify type. Deprecates the function
1376 silc_server_send_replace_id.
1378 * Added silc_server_send_notify_join to send the JOIN notify type.
1379 Deprecates the function silc_server_send_new_channel_user.
1381 * Added silc_server_send_notify_leave to send LEAVE notify type.
1382 Deprecates the function silc_server_send_remove_channel_user.
1384 * Added silc_server_send_notify_cmode and
1385 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1386 types. Deprecates the silc_server_send_set_mode function.
1388 * Added SERVER_SIGNOFF notify type to indicate that server has
1389 quit. This means that all clients on the channel from that
1390 server will drop. This can be also used when netsplit happens.
1392 Deprecated REMOVE_ID packet type since it is not needed anymore
1395 Added silc_server_send_notify_server_signoff to send the
1396 SERVER_SIGNOFF notify type. Deprecates the function
1397 silc_server_send_remove_id.
1399 Added also silc_server_send_notify_signoff to send the
1400 SIGNOFF notify type.
1402 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1403 SILC protocol from this day on. Changed the protocol
1404 specification as well.
1406 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1407 notify type. It is used between routers to notify about
1408 topic changes on a channel.
1410 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1413 * Partly updated the protocol specification to comply with the
1414 changes now made. It is still though a bit outdated.
1416 * The JOIN notify type now takes one extra argument <Channel ID>.
1417 The packet used to be destined to the channel but now the
1418 JOIN type may be sent as list thus it is impossible to
1419 destine it to any specific channel. By adding this argument
1420 it is again possible.
1422 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Added CREDITS file. The CHANGES and CREDITS file will appear
1425 in the distribution as well.
1427 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1430 types in the server's silcd/packet_receive.c.
1432 * Implemented CMODE and CUMODE to work in router environment.
1434 * Fixed minor encoding and decoding buglet from the
1435 lib/silccore/silcmode.c.
1437 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1440 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1442 * Changed all SilcConfigServer* and silc_config_server* to
1443 SilcServerConfig* and silc_server_config*, respectively.
1446 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Associated the ID (client or server ID) to the Authentication
1449 Payload to avoid any possibility of forging. Updated the
1450 protocol specification and the code accordingly.
1452 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * The RSA key length is now save to the RsaKey context in the
1455 key generation process in lib/silccrypt/rsa.c. The key length
1456 is now used to figure out the maximum size of the block allowed
1457 to be encrypted/signed.
1459 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1460 is equivalent to the silc_mp_mp2bin but does not allocate any
1463 * Changed silc_mp_mp2bin API to take length argument. If it is
1464 non-zero then the buffer is allocated that large. If zero, then
1465 the size is approximated using silc_mp_sizeinbase, which however
1468 * Created Global RNG API which is global RNG that application can
1469 initialize. After initializing, any routine anywhere in the
1470 code (including library) can use RNG without allocating a new
1471 RNG object. This was done to allow this sort of use of the
1472 RNG in code that has no chance to allocate RNG object. All
1473 applications currently allocate this and many routines in the
1474 library use this. Affected file lib/silccrypt/silcrng.[ch].
1476 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1477 it to use the Global RNG API.
1479 * Defined Authentication Payload into protocol specification that
1480 is used during SILC session to authenticate entities. It is
1481 used for example by client to authenticate itself to the server
1482 to obtain server operator privileges.
1484 Implemented this payload into the lib/silccore/silcauth.[ch].
1485 Implemented also routines for public key based authentication
1486 as the new protocol specification dictates.
1488 Moved definitions of different authentication methods from
1489 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1491 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1492 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1493 silc_pkcs_verify_with_hash functions into the file
1494 lib/silccrypt/silcpkcs.[ch].
1496 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * The client entry's userinfo pointer must be always valid.
1499 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1500 will fail since it requires the userinfo. Now, the userinfo
1501 is allocated as "" if actual userinfo does not exist. Actually,
1502 it must exist and it is totally Ok to drop client connections
1503 that does not announce the userinfo. However, we will make
1504 this workaround for now.
1506 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1507 to return the remote port by socket.
1509 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1512 SILC_SERVER_PENDING_EXEC and added an new macro
1513 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1514 data or when error occurs while processing the pending command.
1516 Added new argument `destructor' into silc_server_command_pending
1517 and to the SilcServerCommandPending object. This destructor is
1518 now called after calling the pending callback or if error occurs
1519 immediately. If error occurs the actual pending callback won't
1520 be called at all - only the destructor. The destructor may be
1521 NULL if destructor is not needed.
1523 All this applies for client library code as well. Similar
1524 changes were made there as well for the pending commands.
1526 In the client, the application must now allocate the
1527 SilcClientCommandContext with the silc_client_command_alloc
1530 * Added reference counter to the SilcServerCommandContext. Added
1531 function silc_server_command_alloc and silc_server_command_dup
1534 Same type of functions added to the client library for the same
1537 * Removed the cmd_ident from IDListData away since it is now
1538 global for all connections. It is the command identifier used
1539 in command sending and with pending commands. The affected file
1542 * Added reference counter to the SilcSocketConnection objecet to
1543 indicate the usage count of the object. The object won't be
1544 freed untill the reference counter hits zero. Currently only
1545 server uses this, and client ignores it. The client must be
1546 set to use this too later. The affected files are
1547 lib/silccore/silcsockconn.[ch]. Added also the function
1548 silc_socket_dup to increase the reference counter.
1550 This was mainly added because it is possible that the socket
1551 is removed underneath of pending command or other async
1552 operation. Now it won't be free'd and proper DISCONNECTING
1553 flags, etc. can be set to avoid sending data to connection that
1554 is not valid anymore.
1556 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1557 the connection. After that it sets SILC_SET_DISCONNECTED.
1558 It is, however, possible that the socket data is not still freed.
1559 The silc_server_packet_process now checks that data is not
1560 read or written to connection that is DISCONNECTED. The socket
1561 get's freed when the reference counter hits zero.
1563 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Changed the client operation API: channel_message operation's
1566 `sender' is now the client entry of the sender, not the nickname
1567 and the `channel' is the channel entry, not the channel name.
1569 In the private_message operation the `sender' is now also the
1570 client entry of the sender not the nickname.
1572 Affected file is lib/silcclient/ops.h and all applications
1573 using the client operations.
1575 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1577 * Moved the calling of ops->connect() from connect_to_server_final
1578 into receive_new_id functin since that is the point when the
1579 client is actually allowed to send traffic to network. The
1580 affected file is lib/silcclient/client.c.
1582 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1585 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1586 (if needs broadcasting) instead of broadcasting the packets one
1587 by one which would make a burst in the network traffic.
1589 * Added `broadcast' argument to the functions in silcd/server.[ch]
1590 silc_server_create_new_channel[_with_id] to indicate whether
1591 to send New Channel packet to primary router.
1593 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Added new function into the silcd/server.[ch] files:
1596 silc_server_create_new_channel_with_id to create new channel with
1597 already existing Channel ID.
1599 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1600 lib/silccore/silcpacket.h. This packet is used t send list of
1601 Set Mode payloads inside one packet. Server uses this to set
1602 the modes for the channels and clients on those channels, that it
1603 announced to the router when it connected to it. The protocol
1604 specification has been updated accordingly.
1606 * The silc_server_new_channel did not handle the packet coming
1607 from normal server as it normally does not send that. However,
1608 when it announces its channels it does send it. Implemented
1609 the support for that.
1611 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1612 into the file lib/silccore/id.h.
1614 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1616 * Fixed memory leaks in the functions silc_idlist_del_client,
1617 silc_idlist_del_channel and silc_idlist_del_server in the file
1618 silcd/idlist.c. All of those leaked like a sieve.
1620 * Fixed some small memory leaks in the client's function
1621 silc_client_notify_by_server.
1623 * Added functions into silcd/server.c: silc_server_announce_clients,
1624 silc_server_announce_channels and silc_server_announce_server.
1625 These functions are used by normal and router server to announce
1626 to its primary router about clients, channels and servers (when
1627 router) that we own. This is done after we've connected to the
1630 These functions effectively implements the following packet types:
1631 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1632 and SILC_PACKET_NEW_ID_LIST.
1634 * Added new functions into the silcd/packet_receive.[ch]:
1635 silc_server_new_id_list, silc_server_new_channel_list and
1636 silc_server_new_channel_user_list to handle the incoming
1637 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1639 * Added support of changing Channel ID in the function
1640 silc_server_replace_id. If the server that announces a channel
1641 to the router already exists in the router (with same name but
1642 with different Channel ID), router is responsible to send
1643 Replace ID packet to the server and force the server to change
1644 the Channel ID to the one router has.
1646 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1647 client that the Channel ID has been changed by the router. The
1648 normal server sends this to the client. Client must start using
1649 the new Channel ID as the channel's ID.
1651 Implemented handling of this new type into lib/silcclient/client.c
1652 into the function silc_client_notify_by_server.
1654 * Added new function silc_idlist_replace_channel_id into the files
1655 silcd/idlist.[ch] to replace the Channel ID.
1657 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Call silc_server_command_identify_check always when processing
1660 the IDENTIFY command in silcd/command.c
1662 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1665 send keepalive packets. The packet can be sent by clients,
1666 servers and routers.
1668 Added function silc_socket_set_heartbeat into the file
1669 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1670 If not set, the heartbeat is not performed. The actual
1671 heartbeat is implemented in the low level socket connection
1672 library. However, application is responsible of actually
1675 Added silc_server_send_heartbeat to send the actual heartbeat
1676 packet into silcd/packet_send.[ch]. Server now performs
1677 keepalive with all connections.
1679 * Added silc_task_get_first function into lib/silcutil/silctask.c
1680 to return the timeout task with shortest timeout. There was a bug
1681 in task unregistration that caused problems. TODO has been
1682 updated to include that task system must be rewritten.
1684 * The client library will now resolve the client information when
1685 receiving JOIN notify from server for client that we know but
1686 have incomplete information.
1688 * Rewrote parts of silc_server_remove_from_channels and
1689 silc_server_remove_from_one_channel as they did not remove the
1690 channel in some circumstances even though they should've.
1692 * Encryption problem encountered in server:
1694 The LEAVE command used to send the Channel Key packet to the
1695 router immediately after generating it. However, the code
1696 had earlier sent Remove Channel user packet but not immediately,
1697 ie. it was put to queue. The order of packets in the router
1698 was that Channel Key packet was first and Remove Channel User
1699 packet was second, even though they were encrypted in the
1700 reverse order. For this reason, MAC check failed. Now, this
1701 is fixed by not sending the Channel Key packet immediately but
1702 putting it to queue. However, this is more fundamental problem:
1703 packets that are in queue should actually not be encrypted
1704 because packets that are sent immediately gets encrypted
1705 actually with wrong IV (and thus MAC check fails). So, packets
1706 that are in queue should be encrypted when they are sent to
1707 the wire and not when they put to the queue.
1709 However, the problem is that the current system has not been
1710 designed to work that way. Instead, the packet is encrypted
1711 as soon as possible and left to the queue. The queue is then
1712 just purged into wire. There won't be any fixes for this
1713 any time soon. So, the current semantic for packet sending
1716 o If you send packet to remote host and do not force the send
1717 (the packet will be in queue) then all subsequent packets to the
1718 same remote host must also be put to the queue. Only after the
1719 queue has been purged is it safe again to force the packet
1722 o If you send all packets immediately then it safe to send
1723 any of subsequent packets through the queue, however, after
1724 the first packet is put to queue then any subsequent packets
1725 must also be put to the queue.
1727 Follow these rules and everything works fine.
1729 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Added new function silc_server_remove_clients_by_server to
1732 remove all client entries from ID list when the server connection
1733 is lost. In this case it is also important to invalidate all
1734 client entires as they hold the invalid server entry. This
1735 fixes fatal bug when server has lost connection and will reconnect
1738 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Made some sanity checks to silc_server_daemonise like to check
1741 whether the requested user and group actually exists.
1743 * Added sanity check to SKE's silc_ske_responder_finish to check
1744 that the public and private key actually is valid.
1746 * Invalidate the client's nickname when receiving Replace ID
1747 packet and the Client ID is being replaced. This means that the
1748 server will query the nickname if someone needs it (client)
1751 * Sort the ID Cache in client library when the ID Cache data
1752 has changed (needs sorting).
1754 * Do not allow for SILC client to create several connections to
1755 several servers. The client does not support windows right now
1756 and generating multiple connections causes weird behaviour.
1758 Irssi-silc client does support windows and can handle several
1759 connections without problems, see: www.irssi.org and SILC plugin.
1761 * Fixed some places where client was added to the IDList. The
1762 rule of thumb is following (in order to get everything right):
1763 If the client is directly connected local client then the
1764 `connection' argument must be set and `router' argument must be
1765 NULL to silc_idlist_add_client function. If the client is not
1766 directly connected client then the `router' argument must
1767 bet set and the `connection' argument must be NULL to the
1768 silc_idlist_add_client function.
1770 * The funtion silc_server_packet_send_local_channel actually did
1771 not check whether the client was locally connected or not. It
1772 does that now. Fixed a bug related to LEAVE command.
1774 * Fixed Remove Channel User payload parsing bug in server's
1775 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1777 * The server's silc_server_save_channel_key now checks also the
1778 global ID list for the channel as it might not be in the local
1779 list. Fixed a bug related to LEAVE command.
1781 * Is this the end of the [<unknown>] buglet that has been lurking
1782 around for a long time? A little for loop fix in server's
1783 silc_server_command_whois_parse that is used by both IDENTIFY
1784 and WHOIS command. At least, this was a clear bug and a cause
1785 of one type of [<unknown>] buglet.
1787 * WHOIS and IDENTIFY commands call the function
1788 silc_server_command_[whois/identify]_check function even if
1789 we are not router server.
1791 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Added --with-gmp configuration option. If set the GMP
1794 is always compiled in the SILC source tree. If not set then
1795 it is checked whether the system has the GMP3 installed. If
1796 it has then the GMP won't be compiled (the system's headers
1797 and library is used), if it doesn't have it then the GMP is
1798 compiled in the SILC source tree.
1800 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Changed RSA private exponent generation to what PKCS #1
1803 suggests. We try to find the smallest possible d by doing
1804 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1805 not security fix but optimization.
1807 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Added new config entry [Identity] to fork the server and run
1810 it as specific user and group. A patch from Bostik.
1812 * Imported Dotconf configuration library into lib/dotconf.
1813 This will be used to create the SILC configuration files later.
1814 It will appear in the distsribution after this commit.
1816 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * A big code auditing weekend happening. Auditing code for
1819 obvious mistakes, bugs and errors. Also, removing any code
1822 Removed files for being obsolete:
1824 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1825 inline in the file lib/silcutil/silcbuffer.h)
1827 o lib/silcutil/silcbufutil.c (the header has inline versions)
1829 Changed code to fix possible error conditions:
1831 o The buffer formatting routines now check that the destination
1832 buffer really has enough space to add the data. This applies for
1833 both buffer formatting and unformatting
1834 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1835 unformatting was changed to accomodate following rules:
1836 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1837 sent to the function while XXX_*STRING will not allocate or copy
1838 the data into the buffer. Instead it sets the pointer from the
1839 buffer into the pointer sent as argument (XXX_*STRING used to
1840 require that the pointer must be allocated already). This change
1841 makes this whole thing a bit more consistent and more optimized
1842 (note that the data returned in the unformatting with XXX_*STRING
1843 must not be freed now). The routines return now -1 on error.
1845 o Tried to find all code that use buffer_format and buffer_unformat
1846 and added return value checking to prevent formatting and
1847 especially unformatting errors and possible subsequent fatal
1850 o Changed ske->x and ske->KEY to mallocated pointers in
1851 lib/silcske/silcske.h. Fixed possible data and memory leak.
1853 o Added return value checking to all *_parse* functions. Fixed
1854 many memory leaks as well.
1856 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1857 so that buffer overflows would not happen. All code now also
1858 checks the return value as it can fail.
1860 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Added reconnection support to server if the normal server looses
1863 its connection to the router (for example if router is rebooted).
1864 The server performs normal reconnection strategy implemented
1865 to the server. Affected file silcd/server.c.
1867 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Added new packet type SILC_PACKET_SET_MODE that is used to
1870 distribute the information about changed modes (for clients,
1871 channels and clients channel modes) to all routers in the
1872 network. Updated the protocol specification accordingly.
1874 Added functions into silcd/packet_send.c and
1875 silcd/packet_receive.c: silc_server_send_set_mode,
1876 silc_server_set_mode.
1878 Added new files silcmode.[ch] into lib/silccore that implements
1879 the encoding and decoding of Set Mode Payload. Added new type
1880 SilcSetModePayload. Moved the definitions of different modes
1881 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1883 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Oops, a little mistake in server's connection authentication
1886 protocol. The protocol is not ended with FAILURE but with
1887 SUCCESS if the authentication is Ok. :) Affected file is
1890 * Implemented NICK_CHANGE notify handling in server in the file
1891 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1892 the local clients on the channel. After the changing nickname
1893 in router environment snhould work and the [<unknown>] nickname
1894 should appear no more.
1896 The silc_server_replace_id function that receives the Replace ID
1897 payload now sends the NICK_CHANGE notify type also in the file
1898 silcd/packet_receive.c
1900 * Changed WHOIS and IDENTIFY command to support the maximum amount
1901 of arguments defined in protocol specs (3328 arguments). This
1902 fixed a bug that caused problems when there were more than three
1905 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * Added extra parameter, command identifier, to the
1908 silc_client_send_command so that explicit command identifier
1911 Changed that ID list routines uses specific command identifier
1912 when sending WHOIS/IDENTIFY requests to the server so that they
1913 can be identified when the reply comes back.
1915 Affected files lib/silcclient/command.[ch],
1916 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1918 * Added `sender' argument to silc_server_packet_send_to_channel
1919 to indicaet the sender who originally sent the packet to us
1920 that we are now re-sending. Ignored if NULL. Affected file
1921 silcd/packet_send.[ch].
1923 * Added some server statistics support in silcd/server_internal.h
1924 SilcServerStatistics structure and around the server code. Also
1925 send some nice statistics information when client is connecting
1928 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Fixed channel ID decoding in server's JOIN command reply in
1931 silcd/command_reply.c
1933 * Fixed braodcasting of replace ID payload to not to send it if
1934 we are standalone server in silcd/packet_receive.c.
1936 * Fixed all channel message sending routines to not to send
1937 packets to clients that has router set, since they are routed
1938 separately in the same function earlier. Affects file
1939 silcd/packet_send.c and all channel packet sending functions.
1941 * In USERS reply, res_argv[i] are not allocated, the table
1942 is allocated. Thus changed that free the table, not its
1945 * In server's whois_check and identify_check if the client is
1946 locally connected do not send any WHOIS commands - they are not
1949 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Fixed some minor bugs in client when sending WHOIS command. The
1952 arguments was in wrong order.
1954 * Removed statis function add_to_channel from server in
1955 silcd/command.c that was previously used with the joining but
1958 * Tested USERS command in router environment successfully with two
1959 routers, two servers and two clients.
1961 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Reorganized the USERS command and command reply in client library
1964 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1965 When the command is given by user we register a pending command
1966 callback that will reprocess the command after the reply has been
1967 received from the server. When reprocessing the packet we then
1968 display the information. Thus, the USERS information is displayed
1969 now in the command callback instead of in the command reply
1970 callback. The processing of the command is same as previously
1971 when server has sent the command reply in the JOINing process.
1973 * Added to USERS command in silcd/command_reply.c to join the client,
1974 we didn't use to know about, to the channel after we've created
1975 a client entry for it. Also, for clienet we did know already still
1976 check whether it is on the channel or not and add it if not.
1978 * Removed silc_server_command_join_notify as the function and its
1981 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Changed the client's pending command handling to the same as the
1984 server's pending command handling. It is also now possible to
1985 execute command reply functions from other command reply
1986 function as the function callbacks for commands and command
1987 replies are one and same. The pending commands are not static
1988 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1989 in client connection context. Thus, pending commands are server
1990 connection specific as it is convenient.
1992 Changed the function silc_client_command_pending and
1993 silc_client_command_pending_del and added new function
1994 silc_client_command_pending_check. Removed the
1995 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1998 * Added cmd_ident, current command identifier, to the client
1999 connection context in lib/silcclient/client.h to keep track on
2000 command identifiers used in command sending. Client's command reply
2001 function handling now supports the mandatory command identifiers.
2003 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2004 funtions in client to fully support pending command callbacks.
2006 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2007 as one of the arguments to the application in the command reply
2010 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2011 before first releasing SILC but came back. Now it is removed again
2012 and should come back nomore. The FORWARDED flag was used only
2013 by the JOINing procedure by forwarding the command packet to router.
2014 Now, the JOINing procedure has been changed to more generic (due
2015 to various router environment issues) and FORWARDED is not needed
2016 anymore for anything. The protocol specification is yet to be
2019 Now, removed silc_server_packet_forward from server and the flag
2020 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2022 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Renamed NAMES command to USERS command. The NAMES was named that
2025 due to historical reasons. Now it is renamed. Also, rewrote
2026 parts of the USERS command. The nickname list is not sent anymore
2027 by the server. Only Client ID and mode lists are sent in the USERS
2028 command. Changed this also to the protocol specification.
2030 The client now resolves the names and stuff after it receives
2031 the USERS list from the server when joining to the channel.
2033 * WHOIS and IDENTIFY commands has been changed to support multiple
2034 Client ID's per command. One can now search for multiple users
2035 in the network by sending only one WHOIS or IDENTIFY command.
2036 Changed the code and the protocol specifications.
2038 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2039 uses silc_server_command_whois_parse to parse the request. */
2041 * If normal server, do not parse the WHOIS and IDENTIFY requests
2042 before sending it to the router. Saves some time.
2044 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Fixed JOIN command on client library. Wrong number of arguments
2047 used to crash the client.
2049 * Added silc_server_channel_has_global function to check whether
2050 channel has global users or not.
2052 * Added silc_server_channel_has_local function to check whether channel
2053 has locally connected clients on the channel.
2055 * The silc_server_remove_from_one_channel now checks whether the
2056 channel has global users or not after given client was removed from
2057 the channel. It also checks whether the channel has local clients
2058 on the channel anymore. If it does not have then the channel entry
2059 is removed as it is not needed anymore.
2061 * The silc_server_notify now checks on JOIN notify whether the joining
2062 client is one of locally connected or global. If it is global then
2063 the channel has now global users on the channel and that is marked
2064 to the channel entry. Also, it now saves the global client to
2065 global list who is joining and JOINs it to the channel. This is
2066 for normal server, that is.
2068 Changed silc_server_send_notify_on_channel,
2069 silc_server_packet_relay_to_channel and
2070 silc_server_packet_send_to_channel check if we are normal server
2071 and client has router set (ie. global client) do not send the
2072 message to that client, as it is already routed to our router.
2074 * Implemented LEAVE notify type handling in silc_server_notify
2077 * Tested LEAVE command in router environment successfully. Tested
2078 with two routers, two servers and two clients.
2082 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2084 * Implemented SIGNOFF notify type handling in silc_server_notify
2087 * silc_server_remove_id now removes the client entry from all channels
2088 it has joined and thusly sends SIGNOFF notify type.
2090 * Rewrote the NAMES list generation in server by removing two excess
2091 loops. The lists are created now inside one loop.
2093 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * silc_server_remove_channel_user checks now also global list
2096 for channel and client.
2098 * silc_server_new_channel_user checks now both local and global
2099 list for channel and client. Fixed a bug in client id decoding.
2100 Used to decode wrong buffer.
2102 * silc_server_channel_message checks now both local and global
2103 list for channel entry.
2105 * Tested channel joining (hence JOIN) in router environment
2106 successfully. Tested with two routers, two servers and two
2109 * Tested channel message sending in router environment successfully.
2111 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Added silc_server_save_channel_key into server.[ch] to save the
2114 received channel key in Channel Key payload processing. It is
2115 also used in JOIN command reply handling.
2117 Equivalent function silc_client_save_channel_key added into
2118 client.[ch] into client library.
2120 * Changed JOIN command reply to send information whether the channel
2121 was created or not (is existing already) and the channel key
2122 payload. Changed protocol specs accordingly.
2124 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2125 the request was sent by ID and not by nickname. Crashed on
2128 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2131 now correctly save the received data.
2133 * silc_server_free_sock_user_data now notifies routers in the
2134 network about entities leaving the network.
2136 At the same time implemented functions silc_server_remove_id
2137 and silc_server_send_remove_id to receive and send REMOVE_ID
2138 packets. The packet is used to notify routers in the network
2139 about leaving entities. The ID removed will become invalid in
2142 * Added function silc_idlist_del_server into server. Removes and
2143 free's server entry from ID list.
2145 * silc_server_private_message function now checks, if we are router,
2146 that the destination ID really is valid ID, naturally.
2148 * In router when NEW_ID packet is received (for new client) the
2149 hash of the Client ID is saved in the ID Cache but the
2150 client->nickname is set to NULL, instead of putting the hash
2153 IDENTIFY command now also checks that client->nickname must be
2154 valid. If it is not if will request the data from the server who
2155 owns the client. Added new function
2156 silc_server_command_identify_check.
2158 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2159 to set the command to already allocated Command Payload.
2161 * Tested private message sending in router environment with two
2162 routers, two servers and two clients. Fixed minor bugs and now
2165 * Fixed segfault from client's NAMES command. Used to crash if
2168 * Forwarded packets must not be routed even if it is not destined
2169 to the receiver. Changed server code comply with this.
2171 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2173 * Added `require_reverse_mapping' boolean value to ServerParams
2174 structure. If TRUE (not default) the server will require that
2175 the connecting host has fully qualified domain name.
2177 If the reverse mapping is not required and hostname could not be
2178 found the IP address is used as hostname.
2180 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Implemented version string checking to both client and server.
2183 The check is incomplete currently due to the abnormal version
2184 strings used in development version of SILC.
2186 * Changed all command functions in server to use the new
2189 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Changed char *data to unsigned char *data in ID Cache system to
2192 support binary data as ID Cache data. Changed code to support
2193 binary data in lib/silccore/idcache.c.
2195 * Renamed silc_server_packet_relay_command_reply to
2196 silc_server_command_reply as it is normal packet receiving
2197 function. Rewrote the function to accept command replys for
2198 servers and not only for clients.
2200 * Mark remote router always as registered server if we are connecting
2201 to it. Otherwise, commands sent by the router to us are ignored.
2203 * All ID List find routines now returns the ID Cache Entry pointer
2204 as well if requested.
2206 * WHOIS command works now in router environment, tested with two
2207 routers, two servers and two clients.
2209 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2210 in router environment (as it is almost equivalent to WHOIS) but
2211 hasn't been tested thoroughly. Added new functions:
2213 silc_server_command_identify_parse
2214 silc_server_command_identify_send_reply
2215 silc_server_command_identify_from_client
2216 silc_server_command_identify_from_server
2218 * Disabled route cache adding because adding two different ID's with
2219 same IP replaces the old cache entry thus giving wrong route.
2220 The entry->router->connection is always the fastest route anyway
2221 so route cache may not be needed. Of course, new routes maybe
2222 established after receiving the ID when the entry->router->connection
2223 might not be anymore the most optimal.
2225 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Add route cache for received ID for fast routing.
2229 * Added silc_server_packet_route to route received packet on router
2230 that is not destined to us.
2232 * Renamed silc_server_get_route to silc_server_route_get.
2234 * Added id_string and id_string_len fields into SilcServer to
2235 include encoded ServerID for fast comparing without excess
2236 encoding of the ID's.
2238 * Cleaned up WHOIS command on server side. Added following static
2241 silc_server_command_whois_parse
2242 silc_server_command_whois_check
2243 silc_server_command_whois_send_reply
2244 silc_server_command_whois_from_client
2245 silc_server_command_whois_from_server
2247 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2248 arguments in command replies. All command functions should be
2249 updated to use this macro.
2251 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Minor typo fixes on command reply handling on server.
2255 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Added silc_server_command_add_to_channel internal routine to add
2258 the client to the channel after router has created the channel and
2259 sent command reply to the server.
2261 * Added generic silc_server_send_command to send any command from
2264 * Use static buffer with ID rendering instead of duplicating data.
2266 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Fixed a channel user mode bug when joining to a channel server gave
2269 everybody channel founder rights, oops.
2271 * We mark ourselves as the router of the incoming server connection
2272 if we are router ourselves. This way we can check in some packet
2273 sending functions whether it is locally connected server. For
2274 incoming router connections we put NULL.
2276 * For router sending packets locally means now always sending the
2277 packet cell wide; to local clients and local servers. For normal
2278 server sending packet locally means sending it to only local
2281 * Fixed the JOIN command to really work in router environment. If the
2282 channel is created it is always created by the router. Router is
2283 also responsible of making the initial joining to the channel,
2284 sending JOIN notify to the sending server and distributing
2285 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2286 does not exist server doesn't do anything else but forward the
2287 command to the router which performs everything.
2289 * Added silc_server_send_channel_key function to send the Channel Key
2292 * Added silc_server_create_channel_key to create new channel key. The
2293 channel key is now re-generated everytime someone joins or leaves
2294 a channel, as protocol dictates. Note: channel->key_len is the
2297 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2300 packet_receive.[ch] to separate packet sending and receiving
2301 routines. The server.[ch] now includes everything else including
2302 actual packet processing (writing and reading data) and other
2305 Renamed silc_server_private_message_send_internal to
2306 silc_server_send_private_message. The routine is still though
2307 used only to relay private messages as server does not send
2308 private messages itself.
2310 Renamed silc_server_new_channel to silc_server_create_new_channel
2311 and added new function sicl_server_new_channel that handles the
2312 incoming New Channel packet. Added also new sending function
2313 silc_server_send_new_channel to send New Channel Payload.
2315 * Added new function silc_server_notify to process incoming notify
2316 packet to the server/router. Server may then relay the notify
2317 to clients if needed.
2319 * Added new function silc_server_new_channel_user to process incoming
2320 New Channel User packet. Router will redistribute the packet and
2321 send JOIN notify to its local clients and locally connected servers
2322 if needed. Normal server will send JOIN notify to its local client
2323 on same channel when received this packet. Added also corresponding
2324 sending function silc_server_send_new_channel_user to sent the
2327 * Added boolean route argument to send_notif_to_channel and
2328 packet_send_to_channel functions to attempt to route the packet
2329 if it is TRUE and send only locally if it is FALSE.
2331 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * silc_server_replace_id now broadcasts the received replace ID
2334 packet if it is not broadcast packet already. The router must
2335 broadcast to inform other routers about changed ID.
2337 * Added backpointer to server's router into SilcServer context in
2338 silcd/server_internal.h.
2340 * Fixed silc_server_packet_broadcast to send correct broadcast
2343 * The channel key is now distributed to the local client as soon
2344 as it is received from the router (in router environment) so that
2345 no other packet may be sent for the channel until client has
2348 * silc_server_remove_channel_user now broadcasts the received
2349 Remove Channel User packet if it is not broadcast packet already.
2350 The router must broadcast to inform other routers about removed
2353 * Added users field into SilcPacketContext that is a reference count
2354 of the context. One can increase the reference count by calling
2355 silc_packet_context_dup which is now changed to just increase the
2356 reference count instead of duplicating the data. The reference
2357 count is decresed by calling silc_packet_context_free that will
2358 free the data after the reference count hits zero.
2360 For now on the packet context and everything allocated into it
2361 (including the raw packet from network) must be freed by calling
2362 the new silc_packet_context_free function. Added also new function
2363 silc_packet_context_alloc that must be used now to allocate the
2364 context. This also means that if a routine is asynchronous from
2365 silc_[client/server]_packet_parse_type the packet context must
2366 be duplicated by calling silc_packet_context_dup. Otherwise it
2367 gets free'd after silc_[client/server]_packet_parse_type returns.
2368 Also, one must remember that if packet is duplicated then its
2369 reference count must be decresed by calling the free function as
2370 many times as it was duplicated.
2372 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2373 from both client and server.
2375 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Made joining to a channel working in router environment.
2379 * Cleaned up JOIN command on server side and create function
2380 silc_server_command_join_channel internal routine to make the
2383 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Changed silc_command_pending list to SilcDList. Also, added
2386 `ident' field to SilcServerCommandPending structure to identify
2387 the reply and to call correct callback.
2389 Added silc_server_command_pending_check function to replace the
2390 corresnponding macro. The silc_command_pending list is not
2393 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2394 to set identifier to previously allocated Command Payload. It
2395 is used to set identifier for command when resending Command
2398 * Added silc_command_payload_encode_payload to encode Command
2399 Payload buffer from SilcCommandPayload structure.
2401 * Added silc_argument_payload_encode_payload to encode Argument
2402 payload buffer from SilcArgumentPayload structure.
2404 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Changed WHOIS command to support router connection on server side.
2407 The whois request is always sent to router unless the server is
2408 standalone server. After server has received the reply from the
2409 router will it send the reply to the client.
2411 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2412 broadcast received broadcast packet. The function is used only
2413 by router. The broadcast packet is always sent to the router's
2416 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2417 render given ID to printable string, for log files for example.
2419 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Made basic router to router connections working. At least they
2422 can now connect to each other but nothing really works the way
2423 they are supposed - yet.
2425 * Added new initiator token to RouterConnection configuration
2426 file in silcd/serverconfig.[ch]. It is used to tell whether we
2427 are the initiator to the remote router or whether we'll expect
2428 the other end to connect.
2430 * Moved registering of listener task to silc_server_init, hence
2431 the server starts listenning as soon as it is run, even if it
2432 does not have connections to other routers. Let's see how well
2435 * Changed default connection retry timeouts for more suitable in
2438 * Removed cipher and such arguments from silc_idlist_add_client
2439 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2440 Added new function silc_idlist_add_data to add the keys and stuff
2443 * Added SilcIDListData structure and added it to SilcClientEntry
2444 and SilcServerEntry as their first field in the structure. This
2445 way we can explicitly cast the ID entries to the SilcIDListData
2446 structure and get common data for the entries. In past, we had
2447 to first check what type of connection it is and then cast it to
2448 correct ID entry type. Now, we can directly cast the opaque
2449 pointer to the SilcIDListData (no matter what ID entry it actually
2450 is) and get the data needed.
2452 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2455 in some circumstances even if threre were timeout tasks, though not
2456 IO tasks, but tasks anyway. Now fixed.
2458 * Defined SilcServerConnection structure to hold connection specific
2459 stuff about directly connected servers and routers. The definition
2460 is currently in silcd/server_internal.h. I thought about having
2461 a bit more important role fro this struct but for now it is used
2462 only when connecting to other server (or router actually).
2464 * Added connecting retry support in server when connecting to
2465 router(s). The retry feature implement exponential backoff
2466 algorithm. Also, added SilcServerParams structure to hold default
2467 parameters for server. For now, it include these retry settings
2468 and are hard coded. After server is moded to be as Silc Server
2469 Library this structure will be more important.
2471 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Changed client librarys channel->clients table to SilcList and
2474 changed code accordingly.
2476 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Changed client's channel table to SilcList and changed code
2479 accordingly. Also changed SilcChannelClientEntry to include back-
2480 pointer to the channel so that client entry can use that structure
2481 as list as well and we have fast cross-reference to the channel.
2482 This change dramatically decreased the complexity of channel
2483 handling with client entry and vice versa (removed one extra
2484 loop when searching for channel entry from many functions).
2486 * Changed server->sim from table to SilcDList and changed code
2489 * NAMES command can now be used from user interface. It will show
2490 the user list on the channel, neatly.
2492 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2493 Code now saves realname of the user if it becomes available.
2495 * Renamed configure.in to configure.in.pre and made ./prepare
2496 script to automatically add correct version string to
2497 configure.in which it creates from configure.in.pre.
2499 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * NAMES command reply now shows users mode with the nickname when
2504 * Moved silc_client_ch[u]mode[_char] functions from
2505 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2506 place sucks, they are utility functions and should be in some
2509 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2511 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2514 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Added TRQ (efficient deque and list library) into lib/trq. This is
2519 a very good list library that is currently used in the SILC. Defined
2520 SilcList API over the library because I didn't like the API very
2521 much. See lib/trq/silclist.h for the API and examples of how to
2522 use the API. Fixed various places in the code to use the new
2523 SilcList API. The SilcList is meant for lists that has a structure
2524 already defined as a list. It is not suitable to add just some
2525 context to the list (in TRQ, the context is the list actually).
2527 So, I defined SilcDList that can be used for the purpose where
2528 predefined list structure does not exit. This can be used as
2529 such list. Now some context just can be added to the SilcDList.
2530 Currently this list is not used in the SILC just yet, though there
2531 are a lot places where this can replace dynamically allocated
2532 tables and I will fix these places, later, to use SilcDList.
2533 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2534 and use TRQ internally).
2536 Also fixed some annoying warning messages that the original TRQ
2537 code generated. Also minor changes to TRQ's Makefile.in.
2539 * Added support for querying by Client ID to both WHOIS and
2540 IDENTIFY commands into server, as required by the protocol.
2542 * Removed method function pointers from SilcBuffer structure. They
2543 weren't used to anything and just increased the context size for
2544 no good reason. This change also made silc_buffer_alloc and
2545 silc_buffer_free functions inline functions.
2547 * Disabled command flooding detection support until it's fixed so
2548 that it accepts commands in but does not execute them more than once
2551 * Added silc_net_localhost(), to return local hostname, into
2552 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2553 that must be initialized before calling silc_client_init.
2555 * Added new function: silc_server_send_notify_on_channels to send
2556 notify messages to all channels client has joined. It is assured
2557 that the message is sent only once per client.
2559 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2560 lib/silcutil/silcutil.[ch] as silc_format function. The new
2561 function is generic and is used by server as well, not only by
2562 the logging routines.
2564 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2565 the provided version string was not acceptable. Added new function:
2566 silc_ske_check_version into lib/silcske/silcske.h. The function
2567 must be implemented by the application (client or server) and it
2568 does not reside in the SKE library. The function checks the version
2569 string remote end sent.
2571 * Added back pointers (to opaque context and to SilcSocketConnection)
2572 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2574 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2575 duplicate packet context structure.
2577 * Changed `notify' client operation to send same arguments as client
2578 receives from server except for ID's. ID's are mapped to correct
2579 ID entry and that is returned. Also, if channel entry is not sent
2580 by server but the notify is for channel the channel entry is sent
2581 to application (otherwise application doesn't know that it is for
2582 channel (library gets it from packet's Destination ID)).
2584 * Added silc_client_remove_from_channels into client library to
2585 remove a client from all channels it has joined to. Used when
2586 received SIGNOFF notify from server. Added also new function
2587 silc_client_replace_from_channels to replace old ID entry with
2588 new ID entry on all channels. Used when received NICK_CHANGE
2591 * Fixed ID Cache list handling in silc_idlist_get_client in
2592 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2593 to get (or query) client by ID.
2595 * Updated TODO list.
2597 * Added connection authentication status message defined by the
2598 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2599 support for these into the code in client and server side.
2601 * Added generic function silc_client_send_command to send any command
2602 with variable argument list. Application should use this function
2603 to send commands if the command functions provided by the library
2604 does not suite for the application's user interface needs.
2606 * Added new `failure' client operation. Application is notified about
2607 received failure packet if client is executing a protocol. In this
2608 case the protocol's execution has failed.
2610 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2611 is required by the protocol.
2613 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2614 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2617 * Added status flag to SilcSKE object to indicate realtime status
2618 of the SKE protocol.
2620 * Application receives now exactly same command reply arguments as
2621 the library receives from server. However, if ID is received the
2622 corresponding ID entry is returned to the application (eg. Client
2623 ID is mapped to correct SilcClientEntry entry and that is returned).
2624 Changed command_reply client operation due to this change.
2626 * Changed all ID's in commands and in command replys as ID Payloads.
2627 Change affected both client and server side codes.
2629 All ID's sent in SILC network (with execption of ID's in SILC
2630 Packet header) are sent in ID Payload to support variable length
2633 * Server now notifies nick changes and notifies all clients on
2634 the channels about the new nickname (about the new Client ID,
2637 * Implemented CMODE command to change channel modes. Supports all
2638 channel modes defined by the protocol specs except ban and invite
2639 lists. (Also, private channel key mode is supported but support for
2640 setting private channel key in client is missing, thus, this mode
2641 has no effect on client side (except that server requires that the
2642 client uses private channel key and normal channel traffic does not
2645 Also, invite mode works per se, but INVITE command does not work
2646 yet correctly, so you can set channel as invite only channel but
2647 inviting clients to the channel does not work (it is yet to be
2648 thought what's the best way to do it).
2650 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2651 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2652 Implemented CUMODE command to change user's mode on the channel.
2653 Supports all modes defined by the protocol specs.
2655 * Added NAMES command reply to return users modes on the channel.
2657 * Removed unnecessary and slow ciphers from lib/silccrypt.
2659 * Set SO_KEEPALIVE option to connection sockets by default.
2661 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2663 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2664 redefined the Notify Payload into protocol specs.
2666 * Added silc_id_payload_parse_id to get ID directly from raw
2669 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2672 accept searching by Client ID as well.
2674 * Added support for LEAVE and SIGNOFF notify types in client library.
2676 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2677 to parse ID Payload from raw data.
2679 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Added flags parameter into silc_ske_assemble_security_properties
2682 function in lib/silcske/silcske.[ch].
2684 * Changed notify client operation to fit better for notify messages
2685 sent by server. The notify payload received from server is now
2686 passed to the application (after parsing it to SilcNotifyPayload).
2687 It is application's responsibility to retrieve the arguments
2688 from the payload and show the message the way it wants. The message
2689 sent by server is implementation specific.
2691 * Changed public keys to comply with the protocol specification.
2692 Old public keys are not supported anymore and are not compatible.
2694 * Removed nickname from Channel Payload as the latest draft removed
2695 it. The client must resolve the nickname from the NAMES command
2696 reply received when it joined the channel.
2698 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2700 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Fixed some errors in protocol specification drafts.
2704 * Created lib/silccore/silcnotify.c to implement Notify Payload
2705 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2706 generic payloads described by protocol specifications. The file
2707 includes implementations for ID Payload and Argument Payload.
2709 * Changed Command Payload implementation to use the new Argument
2710 Payload. Changed command_xxxx_payload to command_payload_xxxx
2711 to comply with SILC coding conventions.
2713 * Added suppport for Argument Payload handling in Notify Payload
2714 implementation as protocol requires it. Added the new support
2715 into server and client lib as well.
2717 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Added support for multiple nicknames on same channel. [n] is
2720 added locally to the nickname if there are more than one same
2721 nicknames on the channel.
2723 * Server now sends all nicknames that matched WHOIS request.
2724 Client also shows the list received from server.
2726 * Added TOPIC command to client side. User can now set and show
2727 current topic on channel.
2729 * Added MOTD command to client and server. Also, server sends the
2730 motd when client connects to the server.
2732 * Changed version strings to comply ISO 8601.
2734 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Fixed protocol error handling in client library. It should now
2737 cope even if the SKE fails for some reason.
2739 * Made new protocol specification drafts for submitting to IETF.
2741 * Implemented TOPIC command to server in silcd/command.c.
2743 * Added two new notify types into lib/silccore/silcnotify.h:
2744 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2745 notify nickname change and topic setting/change on a channel.
2747 * API change of command_reply operation in client library. The
2748 application gets now the status type received from server as well.
2750 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2754 * Cras fixed and optimized the packet handling even further and
2755 it should work now. Minor change to the prototype of function
2756 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2758 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Added new function into lib/silcutil/silcschedule.[ch]:
2761 silc_schedule_with_fd to select() a specified fd. The function
2762 returns after timeout expires or data arrives or goes. The
2763 function is used by packet routines to wait that all data is
2764 received from network.
2766 * Fixed data reading from network in lib/silccore/silcpacket.c.
2767 The code now assures that all data is read from the fd and then
2768 continues packet processing. This was a bug fix since the code
2769 used to drop some data in some circumstances.
2771 * Added new function into lib/silcclient/client.[ch]:
2772 silc_client_start_key_exchange to start key exchange after
2773 connection has been established to server. The code internally
2774 now uses this funtion but its main purpose was to provide it
2775 for applications that perform their own connecting. After
2776 application has created a connection it merely calls this
2777 function to start the key exchange between client and server.
2778 The library takes care of everything else after that.
2780 Updated also lib/silcclient/README to explain the usage of
2783 * Do not send to application information that connection has
2784 been established. Application gets notified it by connect
2787 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Applied cras's patch to add silc_schedule_one function. The
2790 function runs scheduler once and returns.
2792 * Fixed the scheduler after cras messed it up. The timeout
2793 handling works now as it's supposed to work.
2795 * Added into lib/silccore/ silcnotify.h to include notify
2796 message types support. Changed silc_server_send_notify*
2797 functions, in server.[ch], to support those new notify types.
2798 Added the support for the notify types into client library,
2799 as well. Added new notify client operation into ops.h in
2802 * Changed silc_server_packet_send_to_channel to send normal
2803 packets instead of just channel message packets. The function
2804 is now used to send the notify packets to channels. It is not
2805 used to send channel message packets anymore, as server never
2808 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2809 va_arg()s as it seems to require it nowadays. I guess, if SILC
2810 is compiled with older va_arg() the new code should work anyway.
2812 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Splitted core library. Core library (lib/silccore) includes
2815 now only SILC protocol specific core (and common) components.
2816 Created new utility library (lib/silcutil) that includes more
2817 generic purpose stuff. The stuff for util library was taken
2818 from the old core library. This was minor and easy split.
2820 * Created SILC Client Library (lib/silcclient) that includes
2821 implementation of the SILC client without user interface. This
2822 was major move from silc/ directory. The code has been changed
2823 so that it is transparent towards the user interface. The
2824 silc/ directory includes now the same user interface as before
2825 and it uses the new client library. Read lib/silcclient/README.
2826 Basicly, the client library performs everything else related
2827 to SILC except user interface handling. Also, configuration
2828 files are considered to be part of user interface and library
2829 does not handle them.
2831 This change also changed a lot of structures, function naming etc.
2832 Most important change was that SilcClientWindow object was
2833 renamed to SilcClientConnection in the client library. Created
2834 also new file lib/silcclient/ops.h. Also added new files
2835 silc/local_command.[ch] and silc/client_ops.[ch].
2837 All these changes were made to make it easier for user interface
2838 designers to create what ever user interface for the SILC client
2841 It is also expected that the server will be moved to lib
2842 directory as well and SILC Server Library will be created;
2843 sometimes in the future.
2845 * Removed Local commands from lib/silccore/silccommand.h as
2846 they are application specific and new client library does not
2847 handle any of those anymore.
2849 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2850 old client implementation in silc/.
2852 * Added support for callback functions in SILC_LOG_* macros.
2853 Application can now set its own callbacks that will be called
2854 instead of using the default functions that will always print
2855 the debug messages to stderr (or stdout). Also, debugging can
2856 now be disabled by setting silc_debug to FALSE and re-enabled by
2857 setting it to TRUE. Note, that logging will still work even
2858 if debugging is disabled.
2860 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2861 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2862 silc_log_reset_debug_callbacks.
2864 * To enable debugging in silc client one must give now -d
2865 option on command line.
2867 * Changed silc_schedule_init to automatically allocate task queues
2868 if they are not allocated before calling it.
2870 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Added GMP 3.1 into math library.
2874 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2877 a channel in SILC network. The packet is used by servers and
2878 routers to notify other routers that user has left a channel.
2879 This little feature was missing until now. Added the feature
2880 to protocol specification as well.
2882 Added functions: silc_server_send_remove_channel_user and
2883 silc_server_remove_channel_user into server.[ch].
2885 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2886 lib/silccore/silcpacket.h. However, they are not implemented
2889 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Fixed joining to a channel and sending channel messages
2892 between server and router. The channel message sending should
2893 now work inside a cell.
2895 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Fixed the private message sending between server and router.
2898 The private message sending should now work inside a cell.
2900 * Added silc_server_replace_id into server.[ch] to replace
2901 existing ID in the SILC network.
2903 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2904 and silc_idlist_replace_server_id into idlist.[ch] in server.
2906 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Fixed the server to server connections. Server can again now
2909 connect to router. Router to router connections probably does
2912 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Added dynamic protocol registering support. Now protocols can
2915 registered and unregistered on the fly. Patch by cras.
2917 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added lib/contrib directory to hold routines that some platforms
2920 don't have but are needed by SILC.
2922 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2923 into lin/contrib to provide getopt() and getopt_long() for
2924 those who don't have it.
2926 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Added AWAY command to client. When away message is set and
2929 client receives a private message packet the client automatically
2930 replies to the sender with the away message.
2932 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2933 bug seemed to be the cause of recent problems when compiling
2936 * Added version detection support to SKE protocol specification
2937 and added the new changes to the SKE implementation as well.
2938 There were other minor changes in the SKE protocol as well.
2940 Many changes in lib/silcske/silcske.[ch] and in
2941 lib/silcske/payload.[ch].
2943 * Added ^U functionality, clear input line. Patch from cras.
2945 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Mainly small bugfixes on core library. Fixed some debugging
2948 logging and buffer overflow in silclog.c.
2950 * Updated config.sub and config.guess on the distribution tree.
2952 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Added command lagging support in server. Client may execute
2955 commands now only once in two seconds.
2957 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Optimized packet reception. MAC computation and checking is now
2960 also more optimized. A lot previously duplicated code is now
2961 used as generic by both client and server.
2963 * Fixed key pair generation in clientutil.c
2965 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Added into lib/silccore/silcbufutil.[ch] new function;
2968 silc_buffer_realloc.
2970 * Moved generic packet sending/encryption functions to
2971 lib/silccore/silcpacket.[ch] from client and server. Some
2972 rewriting of the functions.
2974 * Moved all generic packet reception/decryption functions to
2975 lib/silccore/silcpacket.[ch] from client and server. The
2976 packet processing is now much cleaner in both client and server.
2977 These were major changes in both client and server.
2979 * Created many common functions in server to do packet sending.
2980 Previously code were duplicated a lot, this has been removed
2983 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Rewrote major parts of the ID cache system. Don't know
2986 whether it is better now or not but at least the API is more
2989 * Major rewrite on ID cache stuff on client because of the ID
2990 cache API changes. Added idlist.c to client.
2992 * Also major rewrite on ID cache stuff on server as well.
2993 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2994 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2995 in hand, instead they are all put into the ID cache system now.
2996 All server_idlist_* routines uses ID cache now instead of
2997 traversing its own lists (those lists does not exist anymore).
2998 SilcIDList though still exists. Also, SilcXXXEntry's are
3001 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Finally made the SKE implementation compliant to the protocol
3004 specification. All mp integers are now binary encoded as
3005 opposed being HEX encoded.
3007 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3010 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3011 functions: silc_[encode/decode]_pem. Also added function
3012 silc_encode_pem_file to PEM encode with newlines ('\n') for
3015 * SILC public keys are now encoded either PEM or binary. Same
3016 option is for private keys as well. By default private keys
3017 are binary encoded and public keys PEM encoded. Silly HEX
3018 encoding were removed.
3020 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3021 function to create fingerprints.
3023 * Fixed a bug in SHA1; does not change the original data anymore.
3025 * Partly implemented INFO command on client and server side.
3026 Fixed CLEAR command. Changes to SERVER command; show current
3027 server(s) when giving command without arguments. Added
3028 VERSION command to client.
3030 * Added check to server that unregistered connections cannot
3031 execute commands (unless it is specificly allowed).
3033 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Fixed screen refresh.
3037 * Fixed channel joining bug from client. On some circumstances
3038 client tried to join to a channel it had already joined.
3040 * Added public key verification process into client's protocol.c.
3041 The client now verifies the public key from user and saves
3042 it into ~./silc/serverkeys/ directory.
3044 Added into: clientutil.[ch]: silc_client_verify_server_key.
3046 * Changed SKE protocol's silc_ske_initiator_finish function
3047 to accept callback function that verifies the received public
3048 key. Removed old silc_ske_verify_public_key function.
3050 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3053 silc_pkcs_private_key[_data]_set.
3055 * Made the password and public authentication more cleaner in
3056 server's protocol.c.
3058 * Removed historic and obsolete protocol `channel_auth' from
3059 both client and server.
3061 * Removed wrong way of sending command status messages from
3062 server to client in server's command.c. The old way violated
3063 protocol specification.
3065 Changes to silccore/silccommand.[ch]: removed
3066 silc_command_encode_status_payload -> not needed anymore,
3067 changed silc_command_encode_payload_va to accept extra
3068 argument on variable argument list. The argument type must
3069 now be provided to the function. Also, added new function:
3070 silc_command_encode_reply_payload_va which is same as
3071 normal command_encode_payload_va except command status type
3072 is provided as extra argument.
3074 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Added ~./silc directory handling. The directory includes the
3077 public and private keys for the client.
3079 Added silc_client_check_silc_dir, silc_client_create_identifier
3080 and silc_client_load_keys.
3082 * Implemented SILC protocol compliant public key. Added public
3083 and private key saving to and loading from files.
3085 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3086 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3087 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3088 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3089 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3091 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3092 silc_pkcs_load_[public/private]_key.
3094 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Added silc_server_get_route (route.[ch]) to get connection
3097 data for the fastest route for given ID.
3099 * Implemented INVITE command on client and server. The command
3100 were re-defined in the SILC Protocol Specification and the
3101 implementation now complies with the specification.
3103 * Implemented PING command on client and server.
3105 * Implemented NAMES command on client and server. The server side
3106 supports currently only normal server not router server yet.
3107 Some changes to NAMES definition in SILC protocol specification.
3109 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Implemented LEAVE command on client and server.
3113 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3114 again. This change was made to the protocol as well. Server
3115 should not violate the protocol specification anymore.
3117 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3120 was tested. SOCKS4 was not but should work anyway.
