1 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Cleaned up the CMODE command in the server. It now works
4 correctly and supports all the modes defined in the protocol.
5 Affected file is silcd/command.c.
7 * Added `hmac_name' field to the SilcChannelEntry in the server
8 to hold the default HMAC of the channel. It can be set when
9 creating the channel (with JOIN command). Affected files
12 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
13 type to indicate the change of the current cipher and hmac
14 on the channel. Client can safely ignore the <cipher> argument
15 (if it chooses to do so) since the CHANNEL_KEY packet will
16 force the channel key change anyway. The <hmac> argument is
17 important since the client is responsible of setting the new
18 HMAC and the hmac key into use.
20 * Fixed the CMODE command in the client library as well.
22 * Tested CMODE command in router environment successfully.
24 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Show the version of the remote client (or server) when connecting
27 to the server. It is logged to the log file. Affected file
30 * Fixed the KILLED notify handling in the client library. The
31 client must be removed from all channels when receiving the
34 Also, do not remove the client entry when giving the KILL
35 command but when the KILLED notify is received.
37 * Removed silc_idlist_find_client_by_nickname from the server.
38 Not needed anymore. Affected files silcd/idlist.[ch].
40 * Implemented the CHANNEL_CHANGE notify type handling to the
41 server. Affected file silcd/server.c.
45 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * Added silc_server_send_notify_invite to send the INVITE
48 notify between routers.
50 * Implemented the INVITE command correctly to the server.
52 * Implemented the INVITE notify type handling in the server.
54 * Implemented the INVITE command to the client library and on the
57 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
59 * Added function silc_server_get_client_resolve to find the
60 client entry by ID from all ID lists and then resolve it
61 (using WHOIS) if it cannot be found. Affected file is
64 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * Implemented the BAN command to the client library.
68 * The JOIN command in the server now checks the invite list
71 * Changed the silc_command_reply_payload_encode_va and the
72 silc_command_payload_encode_va to support that if argument is
73 NULL it ignores and checks the next argument. Affected file
74 lib/silccore/silccommand.c.
76 * Added silc_server_send_notify_ban to send the BAN notify
79 * Chaned the silc_notify_payload_encode to support that if
80 argument is NULL it ignores and checks the next argument.
81 Affected file lib/silccore/silcnotify.c.
83 * Tested ban lists in router environment successfully.
85 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Implemented BAN command to the server, in silcd/command.[ch].
89 * Removed the BAN and INVITE_LIST modes from the CMODE command
92 * Added function silc_string_match to regex match two strings.
93 Affected files lib/silcutil/silcutil.[ch].
95 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Redefined parts of the SilcChannelEntry in the server to support
98 the new ban and invite lists.
100 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Redefined the INVITE command. The same command can be used to
103 invite individuals to the channel but also to manage the invite
104 list of the channel (to add to and remove from the invite list).
105 Updated the protocol specs.
107 * Added new command SILC_COMMAND_BAN that can be used to manage
108 the ban list of the channel. Updated the protocol specs.
110 * Removed the channel modes: the SILC_CMODE_BAN and the
111 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
112 in the CMODE command. The equivalent features are now available
113 using INVITE and BAN commands. Updated the protocol specs.
115 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
116 in the network about change in the current ban list. The notify
117 type is not used by the client.
119 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
120 support the invite lists.
122 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Added new function silc_string_regexify that converts string
125 including wildcard characters into regex string that can
126 be used by the GNU regex library. Added into the file
127 lib/silcutil/silcutil.[ch].
129 Added silc_string_regex_combine to combine to regex strings
130 into one so that they can be used as one regex string by
131 the GNU regex library. Added into the file
132 lib/silcutil/silcutil.[ch].
134 Added silc_string_regex_match to match two strings. It returns
135 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
137 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Imported GNU regex to the soruce tree into lib/contrib.
140 Fixed some compiler warning from the regex.c.
142 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Fixed MOTD command in the server to work in router environment.
146 * Fixed the MOTD command in the client library to support
147 the server argument in the command.
149 * Added `nickname_len' argument to the silc_idlist_add_client
150 in the server, as the `nickname' argument may be binary data
153 * Added silc_idlist_get_channels to return all channels from
156 * Implemented LIST command to the server. Affected file is
159 * Implemented the LIST command to the client library and on the
162 * Added [<user count>] argument to the LIST command reply.
163 With private channels the user count is not shown.
165 * Updated TODO and README.
167 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
169 * The client entry's data.registered must be TRUE even with
170 global client entry on global client list. The data.registered
171 is used to check whether the client is anymore in the network,
172 for example with WHOWAS command so it must be valid.
174 * Fixed the WHOWAS command in the server. It now actually works
175 in router environment. Added function into silcd/command_reply.c
176 silc_server_command_reply_whowas_save.
178 * Added silc_idlist_purge function to the silcd/idlist.c
179 to periodically purge the ID Cache.
181 * Fixed INFO command in the server. It works now in router
182 environment. Added <server name> argument to the INFO command
183 reply. Updated the protocol specs.
185 * Fixed minor bug in silc_idcache_purge to not purge if the
186 expire value is zero.
188 * Fixed various bugs in WHOIS and IDENTIFY command handling as
189 they were buggy because of the WHOWAS information.
191 * Fixed local command MSG to handle the async resolving of
192 the remote client properly. It used to fail the first MSG.
193 Affected file silc/local_command.c.
195 * Added `data_len' field to SilcIDCache context.
197 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Update TODO. Todo in commands in the server.
201 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
204 used by routers as broadcast packet to inform other routers
205 about the changed user mode.
207 Implemented the notify handling in the server. Affected file is
208 silcd/packet_receive.c. Added the function
209 silc_server_send_notify_umode to the silcd/packet_send.[ch].
211 * Added new generic Channel Payload and deprecated the New Channel
212 Payload. The New Channel Payload is now the generic Channel
215 * Added new argument `mode' to the silc_server_send_new_channel
216 as it is required in the Channel Payload now.
218 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
219 and created a new and real SilChannelPayload to represent the
220 new generic Channel Payload. Implemented the encode/decode
221 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
223 * Added silc_server_get_client_channel_list to return the list
224 of channels the client has joined for WHOIS command reply.
225 Affected file silcd/server.[ch].
227 * Implemented the channel list sending in the WHOIS command reply
228 in server and in the client.
230 Implemented the channel list displaying on the user interface
231 as well. Affected file silc/client_ops.c.
233 * Added silc_channel_payload_parse_list to parse list of Channel
234 Payloads. It returns SilcDList list of SilcChannelPayloads.
235 Client for example can use this function to parse the list of
236 channels it receives in the WHOIS command reply. The caller
237 must free the list by calling silc_channel_payload_list_free.
238 Affected files lib/silccore/silcchannel.[ch].
240 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
242 * Added one new argument <user mode> to the WHOIS command reply
243 to return the mode of the user in SILC. Updated the protocol
246 Implemented it to the server and client.
248 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Fixed the mode printing on the user interface on joining.
251 Affected file silc/client_ops.c.
253 * Implemented the UMODE command and user modes in general to the
254 client library and to the user interface.
256 * Implemented the UMODE command to the server.
258 * The server now sends UNKNOWN_COMMAND error status if client sends
259 unknown command. Affected file silcd/command.c.
261 * All server commands now handle the command identifier the right
262 way when sending the command reply to the client. The client can
263 use to identify the command replies with the identifier.
265 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Added silc_server_get_client_route to resolve the route to
268 the client indicated by the client ID. Affected file is
271 * Added silc_server_relay_packet as general function to relay
272 packet to arbitrary destination. This deprecates functions
273 like _send_private_message_key, _relay_notify etc. Affected
274 file is silcd/packet_send.[ch].
276 Removed silc_server_send_key_agreement,
277 silc_server_send_private_message_key and
278 silc_server_packet_relay_notify functions from the file
279 silcd/packet_send.[ch].
283 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
284 server. Affected file silcd/packet_receive.[ch].
286 * Implemented the KILL command to the client. Implemented the
287 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
288 Affected files lib/silcclient/command[_reply].c and
289 lib/silcclient/client_notify.c. Implemented the KILL notify
290 printing in the user inteface.
292 * Fixed a lot silc_parse_nick memory leaks from the client
293 library in the file lib/silcclient/command.c.
295 * Changed the silc_server_send_notify_on_channels's `sender'
296 argument from SilcSocketConnection to SilcClientEntry to
297 check the sender as entry and not as connection object and not
298 to send to the client provided as argument. The affected file
299 is silcd/packet_send.[ch].
301 * The notify packets that are destined directly to the client used
302 to not to be processed by the server. Now changed that and the
303 server processes all notify packets. After relaying the packet
304 to the client the notify packet is processed in the server.
306 * The silc_server_free_client_data now checks whether there is
307 pending outgoing traffic for the client and purges the data to
308 the network before removing the client entry.
310 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
313 an client is killed from the SILC Network. Updated the protocol
316 Added new function silc_server_send_notify_killed to the
317 silcd/packet_send.[ch].
319 * Added function silc_server_packet_relay_notify to relay notify
320 packets that are destined directly to a client. In this case
321 the server does not process the notify packets but merely relays
322 it to the client. Affected file silcd/packet_send.[ch].
324 Added also silc_server_packet_process_relay_notify to check
325 whereto relay the notify. Affected file is
326 silcd/packet_receive.[ch].
328 * Implemented the KILL command to the server.
332 * Added the backup schema desgined last fall to the protocol
333 specs for everyone to see. The specification is in the
334 *-spec-xx.txt draft and the packet type definitions for the
335 backup routers is in *-pp-xx.txt draft. Thusly, added also
336 new packet type SILC_PACKET_CELL_ROUTERS.
338 * A big security problem in the implementation discovered. The
339 signoff of an client did not cause new channel key generation
340 which it of course should've done. The channel keys must be
341 always re-generated when client leaves (or signoffs) the channel.
342 The silc_server_remove_from_channels funtion now handles
343 the channel key re-generation.
345 * Added `sender' argument to the silc_server_send_notify_on_channels
346 to not to send the client provided as argument. Affected file
347 silcd/packet_send.[ch].
349 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Implemented OPER and SILCOPER commands into the server and
354 * Added silc_auth_verify and silc_auth_verify_data to verify
355 the authentication directly from the authentication payload.
356 It supports verifying both passphrase and public key based
357 authentication. Affected file lib/silccore/silcauth.[ch].
359 * Added `hash' field to the SilcIDListData structure. It is the
360 hash negotiated in the SKE protocol. Affected file is
363 * Slight redesigning of the SilcAuthPayload handling routines.
364 Do not send SilcPKCS but SilcPublicKey as argument.
366 * Implemented the public key authentication support to the
367 serverconfig. The public key is loaded fromthe provided path
368 and saved as authentication data to void * pointer. Thus,
369 changed the unsigned char *auth_data to void *auth_data;
371 * Fixed SHUTDOWN command to send the reply before the server
372 is shutdown. :) Affected file silcd/command.c.
374 * Fixed fatal bug in CONNECT command. The hostname was invalid
375 memory and server crashed. Affected file silcd/command.c.
377 * Fixed fatal bug in CLOSE command. The server_entry became
378 invalid but was referenced later in the command. Affected file
381 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Fixed fatal bug in failure packet handling. Server ignored
384 the failure and thus crashed when it came.
388 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
391 that the command may be executed only once in (about) 2 seconds.
392 The old SILC_CF_LAG flag is same but allows command bursts up
393 to five before limiting.
395 Added the support for CF_LAG and CF_LAG_STRICT flags to the
396 server code. Various commands now includes the CF_LAG_STRICT
397 flag to disallow any kind of miss-use of the command.
399 * Fixed the silc_buffer_unformat to not to allocate any data
400 if the length of the data is zero. It used to allocate the
401 length + 1. Affected file lib/silcutil/silcbuffmt.c.
403 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Changed the format of AdminConnection configuration section
406 in the server. Added username of the admin to the format.
407 Affected files silcd/serverconfig.[ch].
409 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
410 to return admin configuration data by host, username and/or
413 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Implemented WHOWAS command to the server. Added the functions:
417 silc_server_command_whowas_parse,
418 silc_server_command_whowas_send_reply,
419 silc_server_command_whowas_from_client and
420 silc_server_command_whowas_from_server
422 * Added <Client ID> argument to the WHOWAS command reply. Updated
423 the protocol specs accordingly.
425 * Implemented WHOWAS command and command_reply to the client
428 Implemented the WHOWAS printing on the user interface.
430 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Added new argument to the WHOWAS command reply, the real name.
433 It is an optional argument. Updated the protocol specs.
435 * Added SilcIDCacheDestructor callback that is registered when
436 the SilcIDCache is allocated. The callback is called when
437 an cache entry in the ID Cache expires, or is purged from the
438 cache. Added into lib/silccore/idcache.[ch].
440 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
441 to destruct the client entries when the cache entry expires.
442 Other ID Cache's in server and in the client library ignores
445 * If the ID Cache entry's `expire' field is zero then the entry
446 never expires. Added boolean `expire' argument to the
447 silc_idcache_add function in the lib/silccore/idcache.[ch].
448 If it is TRUE the default expiry value is used.
450 * Added silc_server_free_client_data_timeout that is registered
451 when client disconnects. By default for 5 minutes we preserve
452 the client entry for history - for WHOWAS command.
454 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Added support to the server to enforce that commands are not
457 executed more than once in 2 seconds. If server receives
458 commands from client more frequently, timeout is registered
459 to process the commands. Affected file silcd/command.c.
460 Added new function silc_server_command_process_timeout.
462 * Changed NICK_NOTIFY handling in client library to check that
463 if the client's nickname was changed, so there is no need to
464 resolve anything from the server.
466 * Removed error printing from the WHOIS and IDENTIFY commands.
467 If error occurs then it is ignored silently in the client library.
468 The application, however, may map the received error to
469 human readable error string. The application currently maps
470 the NO_SUCH_NICKNAME error to string.
472 * Made the command status message public to the application. Moved
473 them from lib/silcclient/command_reply.c to
474 lib/silcclient/command_reply.h. The application can map the
475 received command status to the string with the
476 silc_client_command_status_message function.
478 * Added check to the server to check that client's ID is same
479 as the Source ID in the packet the client sent. They must
482 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Added dist-bzip hook to the Makefile.am to make bzip2
485 compressed distributions.
487 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Server now enforces the maximum length for the nickname and
490 the channel as protocol specification dictates. 128 bytes for
491 nickname and 256 bytes for channel name.
493 * Moved the WHOIS printing to the application. The client libary
494 does not print out the WHOIS information anymore, the application
495 must do it. Renamed silc_client_command_reply_whois_print to
496 the silc_client_command_reply_whois_save.
498 The client's idle time is also sent to the application now, and
499 the idle is shown on screen.
501 * Added silc_client_command_reply_identify_save to save the
502 received IDENTIFY entries.
504 * Do not check for channel private keys in message sending and
505 reception if the channel does not have the PRIVKEY mode set.
506 Affected file lib/silclient/client_channel.c.
508 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
511 just surfaced after chaning the JOIN procedure.
513 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Added silc_client_get_clients_by_list to get client entries
516 from Client ID list, that is returned for example by JOIN
517 and USERS command replies. The application should use this
518 function for example when JOIN command reply is received to
519 resolve the clients already on the channel (library does not
520 do that anymore as USERS command reply is not used in the JOIN
521 procedure anymore). Affected files lib/silcclient/silcapi.h and
522 lib/silcclient/idlist.c.
524 * JOIN command reply and USERS command reply returns now SilcBuffer
525 pointers instead of unsigned char pointers when returning
526 the client list and mode list.
528 * Added <Client ID> argument to the JOIN command reply, mainly
529 for the server to identify for which client the command was
530 originally sent. Updated protocol specs accordingly.
532 * Added SilcDlist private_key pointer to the SilcChannelEntry
533 in the client to support the channel private keys. Affected
534 file is lib/silcclient/idlist.h.
536 * Added SilcChannelPrivateKey argument to the function
537 silc_client_send_channel_message so that application can choose
538 to use specific private ke if it wants to. If it is not provided,
539 the normal channel key is used, unless private keys are set.
540 In this case the first (key that was added first) is used
541 as the encryption key.
543 * Implemented the support for channel private key handling.
544 Implemented the following functions:
546 silc_client_add_channel_private_key,
547 silc_client_del_channel_private_keys,
548 silc_client_del_channel_private_key,
549 silc_client_list_channel_private_keys and
550 silc_client_free_channel_private_keys
552 Affected file lib/silcclient/client_channel.c.
554 * Added the support for the private keys in the channel message
555 sending and encryption and in the message reception and
556 decryption. Affected funtions are
557 silc_client_send_channel_message and silc_client_channel_message.
559 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Added SKE's key verify callback to the client library's
562 KE protocol context. Affected files lib/silcclient/protocol.[ch].
564 * Removed the statement that server (or router) must send USERS
565 command reply when joining to the channel so that the client
566 knows who are on the channel. Instead, the client list and
567 client's mode list is now sent in the JOIN command reply to the
568 client who joined channel. This is better solution.
570 * Added function silc_server_get_users_on_channel and function
571 silc_server_save_users_on_channel to the silcd/server.[ch].
573 * Removed function silc_server_command_send_users from the
576 * Do not show topic on the client library anymore. The topic is
577 sent in the command reply notify to the application and the
578 application must show the topic now.
580 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Added client searching by nickname hash into the IDENTIFY and
583 WHOIS commands in the server as they were clearly missing from
584 them. Affected file is silcd/command.c.
586 * Fixed a bug in private message receiving in the client library.
587 The remote ID was freed and it wasn't supposed, now it is
590 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Minor fix to the channel payload; allocate the data area, as it
593 needs to be of specific length.
595 * If the key agreement port is zero then the operating
596 system will define the bound port. Affected files are
597 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
599 * Added new function silc_channel_payload_decrypt into the file
600 lib/silccore/silcchannel.[ch].
602 * Moved the channel message etc, check from silc_packet_decrypt
603 to applications. The library calls now a generic
604 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
605 when the packet is either normal or special. This was done to
606 allow more wide range of checking that was not allowed when
607 the code was in library. Now applications can do virtually any
608 checks to the packet and return to the library the decision how
609 the packet should be processed. Affected files are
610 lib/silccore/silcpacket.[ch].
612 Added silc_server_packet_decrypt_check to the server and
613 silc_client_packet_decrypt_check to the client library.
615 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
616 to send with specified source and destination information.
618 * Channel message delivery between routers was broken after the
619 channel key distribution was fixed earlier. The channel key
620 was used be to distributed to other routers as well which is not
621 allowed by the protocol. Now this is fixed and channel keys
622 really are cell specific and the channel message delivery between
623 routers comply with the protocol specification.
625 * Fixed various commands in server to check also the global list
626 for the channel entry and not just the local list. The affected
627 file silcd/command.c.
629 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added assert()s to buffer formatting and unformatting routines
632 to assert (if --enable-debug) when error occurs. Affected
633 file: lib/silcutil/silcbuffmt.c.
635 * Changed to auto-reconnect to check whether the remote host is
636 router and register the re-connect timeout if it is. It used
637 to check that whether we are normal server, but router must do
638 auto-reconnect with another router as well. Affected file
641 * Removed the [<key len>] option from CMODE command as the cipher
642 name decides the key length, nowadays. See the defined ciphers
643 from the protocol specification.
645 * Added [<hmac>] option to the CMODE command to define the HMAC
646 for the channel. Added SILC_CMODE_HMAC channel mode.
648 * Added [<hmac>] option for the JOIN command so that user can
649 select which HMAC is used to compute the MACs of the channel
652 * Added Hmac field to the Channel Message Payload. The integrity
653 of plaintext channel messages are now protected by computing
654 MAC of the message and attaching the MAC to the payload. The
655 MAC is encrypted. Now, it is clear that this causes some
656 overhead to the size of the packet but rationale for this is that
657 now the receiver can verify whether the channel message decrypted
658 correctly and also when private keys are set for the channel the
659 receiver can decrypt the packet with several keys and check from
660 the MAC which key decrypted the message correctly.
662 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
663 lib/silccrypt/silccipher.[ch].
665 * Added silc_hash_len to return the digest length into the
666 lib/silcrypt/silchash.[ch].
668 * Rewrote parts of Silc Channel Payload interface in the
669 lib/silccore/silcchannel.[ch]. The encode function now also
670 encrypts the packet and parse function decrypts it.
672 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Fixed a minor formatting bug in the SKE's key material processing.
675 It actually might have processed the keys wrong way resulting
678 * Redefined the mandatory HMAC algorithms and added new algorithms.
679 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
680 and hmac-md5 truncated to 96 bits. The mandatory is now
681 hmac-sha1-96. Rest are optional (including the one that used
682 to be mandatory). Rationale for this is that the truncated HMAC
683 length is sufficient from security point of view and can actually
684 make the attack against the HMAC harder. Also, the truncated
685 HMAC causes less overhead to the packets. See the RFC2104 for
688 * Added new [hmac] configuration section. The SKE used to use
689 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
690 is of course wrong. The official names that must be proposed in
691 the SKE are the ones defined in the protocol specification
692 (hmac-sha1-96 for example). The user can configure any hmac
693 using any hash function configured in the [hash] section. At
694 least, the mandatory must be configured.
696 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
698 * Added HMAC list to the SKE proposal list. It has now both
699 hash algorithm list and HMAC list. This makes the protocol
700 incompatible with previous versions. The SKE now seems to work
701 the way it is supposed to work, for the first time actually.
703 * Defined plain Hash algorithms to the protocol specification.
706 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Implemented support for key agreement packets into the server.
709 Added functions silc_server_key_agreement and
710 silc_server_send_key_agreement. Other than these functions,
711 server has nothing to do with this packet.
713 * Added support for private message key packets into the server.
714 Added functions silc_server_private_message_key and
715 silc_server_send_private_message_key.
719 * Changed the silc_[client|server]_protocol_ke_set_keys to be
720 called in the protocol's final callback instead in the END
721 protocol state. This makes a little more sense and in the same
722 time in client we can use the same protocol routines for normal
723 key exchange and to key agreement packet handling as well.
725 * Added to both client's and server's KE protocol context the
726 SilcSKEKeyMaterial pointer to save the key material. We will
727 bring the key material to the protocol's final callback by doing
728 this. The final callback must free the key material.
730 * Added SKE's packet_send callback into client's KE protocol
731 context so that the caller can choose what packet sending function
732 is used. This way we can use different packet sending when
733 doing normal SKE when doing key agreement packet handling (in
734 the key agreement packet handling we do not want to encrypt
737 * Implemented the responder side of the key agreement routines
738 in the client. The client can now bind to specified port and
739 accept incoming key negotiation. The key material is passed
740 to the application after the protocol is over.
742 * Implemented the processing of incoming Key Agreement packet
743 in the client. Added function silc_client_key_agreement to
746 * Implemented the intiator side of the key agreement routines
747 in the client. The client can now initiate key agreement with
748 another remote client. The key material is passed to the
749 application after the protocol is over.
751 * Created client_keyagr.c to include all the key agreement
754 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
755 SILC_TASK_CALLBACK except that it is not static.
757 * Created client_notify.c and moved the Notify packet handling
758 from the client.[ch] into that file.
760 * Created client_prvmsg.c and moved all private message and
761 private message key routines from the client.[ch] into that file.
763 * Create client_channel.c and moved all channel message and
764 channel private key routines from the client.[ch] into that file.
766 * Changed silc_client_get_client_by_id_resolve to resolve with
767 WHOIS command instead of IDENTIFY command, in the file
768 lib/silclient/idlist.c.
770 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Implemented the SKE's responder side to the Client library.
774 * When FAILURE is received to the protocol do not trust it
775 blindly. Register a timeout to wait whether the remote closes
776 the connection as it should do it, only after that process the
777 actual failure. This was changed to both client and server.
779 * Added client_internal.h to include some of the structures
780 there instead of client.h in lib/silcclient/.
782 * Added function silc_task_unregister_by_callback to unregister
783 timeouts by the callback function.
785 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Some "Incomplete WHOIS info" errors has been appearing on the
788 log files. Took away the entry->userinfo check from WHOIS
789 reply sending. The entry->userinfo is now " " if client did not
790 provide one. I thought this was fixed earlier but something
791 is wrong still. Let's see if the error still appears.
793 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Fixed a minor bug in the login when the channel key is
796 re-generated in the server. It used to generate the key in
797 wrong order and thus caused problems in the channel traffic.
799 * Fixed a minor bug in channel key distsribution after
800 KICK command. The key was not sent to the router even though
803 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * Added silc_ske_process_key_material_data as generic routine
806 to process any key material as the SILC protocol dictates. The
807 function is used by the actual SKE library but can be used by
808 applications as well. This relates to the private message keys
809 and the channel private keys since they must be processed the
810 same way the normal SILC session keys. The protocol dictates
811 this. Affected files: lib/silcske/silcske.[ch].
813 Added also silc_ske_free_key_material to free the
814 SilcSKEKeyMaterial structure.
816 * Defined silc_cipher_set_key function to set the key for
817 cipher without using the object's method function. The affected
818 files: lib/silccrypt/silccipher.[ch].
820 * Implemented silc silc_client_add_private_message_key,
821 silc_client_add_private_message_key_ske,
822 silc_client_del_private_message_key,
823 silc_client_list_private_message_keys and
824 silc_client_free_private_message_keys functions in the
827 Added functions silc_client_send_private_message_key to send
828 the Private Message Key payload and silc_client_private_message_key
829 to handle incoming Private Message Key payload.
831 * Added Cipher field to the Private Message Key payload to set
832 the cipher to be used. If ignored, the default cipher defined
833 in the SILC protocol (aes-256-cbc) is used.
835 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Removed lib/silcclient/ops.h file.
839 Redefined parts of the SILC Client Library API. Created new
840 file silcapi.h that deprecates the ops.h file and defines the
841 published Client Library API. Defined also private message key
842 API and channel private key API into the file.
844 This is the file that the application must include from the
845 SILC Client Library. Other files need not be included by
846 the application anymore.
848 * Added new key_agreement client operation callback and also
849 defined the Key Agreement library API for the application.
851 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
854 is used by clients to request key negotiation between another
855 client in the SILC network. If the negotiation is started it
856 is performed using the SKE protocol. The result of the
857 negotiation, the secret key material, can be used for example
858 as private message key.
860 Implemented the Key Agreement payload into the files
861 lib/silccore/silauth.[ch].
863 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Redefined ciphers for the SILC protocol. Added some new ciphers
866 and defined the key lengths for the algorithms. Changed the
867 code accordingly. The default key length is now 256 bits.
869 * Fixed SKE key distribution function silc_ske_process_key_material
870 when the key length is more than 128 bits. The default key
871 length in SILC is now 256 bits.
873 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
874 to indicate unsupported algorithm.
876 * Renamed rijndael.c to aes.c and all functions as well.
878 * Fixed a long standing channel key setting bug in client library.
879 Weird that it has never surfaced before.
881 * Fixed bug in channel deletion. If the entire channel is removed
882 then it must also delete the references of the channel entry
883 from the client's channel list as the client's channel entry and
884 the channel's client entry share same memory.
886 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Implemented CONNECT and SHUTDOWN commands in the client.
890 * Implemented CLOSE command to the client.
892 * Added the function silc_idlist_find_server_by_name into the
893 files silcd/idlist.[ch].
895 Added the function silc_idlist_find_server_by_conn into the
896 files silcd/idlist.[ch].
898 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * DIE command was renamed to SHUTDOWN. Updated the both code
903 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
904 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
906 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
909 * Added function silc_server_create_connection function to create
910 connection to remote router. My server implementation actually
911 does not allow router to connect to normal server (it expects
912 that normal server always initiates the connection to the router)
913 so the CONNECT command is only good for connecting to another
916 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
919 or some other client was kicked from the channel.
921 Implemented the handling of the notify type to both client
924 Implemented silc_server_send_notify_kicked to send the KICKED
925 notify. It is used to send it to the server's primary router.
927 * Implemented the KICK command into server and client.
929 * Added `query' argument to the silc_idlist_get_client function
930 to indicate whether to query the client from server or not if
933 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
934 to indicate that the client is not channel founder.
938 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Removed the rng context from SilcPacketContext structure and
941 changed that the packet routine uses the Global RNG API.
943 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added support for quit message that client can "leave" on the
946 channel when it quits the SILC. It is ditributed inside the
947 SILC_NOTIFY_TYPE_SIGNOFF notify type.
949 Added silc_server_free_client_data that will take the
950 signoff message as argument.
952 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
954 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Updated parts of the protocol specification to keep it up
959 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
962 payloads in one packet.
964 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
965 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
966 use now the new List flag.
968 * Also deprecated the following packet types: REPLACE_ID,
969 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
971 * Added list support for Notify packet in server.
973 * Added silc_server_send_notify_channel_change to send the
974 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
975 the silc_server_send_replace_id.
977 * Added silc_server_send_notify_nick_change to send the
978 NICK_CHANGE notify type. Deprecates the function
979 silc_server_send_replace_id.
981 * Added silc_server_send_notify_join to send the JOIN notify type.
982 Deprecates the function silc_server_send_new_channel_user.
984 * Added silc_server_send_notify_leave to send LEAVE notify type.
985 Deprecates the function silc_server_send_remove_channel_user.
987 * Added silc_server_send_notify_cmode and
988 silc_server_send_notify_cumode to send CMODE and CUMODE notify
989 types. Deprecates the silc_server_send_set_mode function.
991 * Added SERVER_SIGNOFF notify type to indicate that server has
992 quit. This means that all clients on the channel from that
993 server will drop. This can be also used when netsplit happens.
995 Deprecated REMOVE_ID packet type since it is not needed anymore
998 Added silc_server_send_notify_server_signoff to send the
999 SERVER_SIGNOFF notify type. Deprecates the function
1000 silc_server_send_remove_id.
1002 Added also silc_server_send_notify_signoff to send the
1003 SIGNOFF notify type.
1005 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1006 SILC protocol from this day on. Changed the protocol
1007 specification as well.
1009 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1010 notify type. It is used between routers to notify about
1011 topic changes on a channel.
1013 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1016 * Partly updated the protocol specification to comply with the
1017 changes now made. It is still though a bit outdated.
1019 * The JOIN notify type now takes one extra argument <Channel ID>.
1020 The packet used to be destined to the channel but now the
1021 JOIN type may be sent as list thus it is impossible to
1022 destine it to any specific channel. By adding this argument
1023 it is again possible.
1025 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Added CREDITS file. The CHANGES and CREDITS file will appear
1028 in the distribution as well.
1030 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1033 types in the server's silcd/packet_receive.c.
1035 * Implemented CMODE and CUMODE to work in router environment.
1037 * Fixed minor encoding and decoding buglet from the
1038 lib/silccore/silcmode.c.
1040 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1043 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1045 * Changed all SilcConfigServer* and silc_config_server* to
1046 SilcServerConfig* and silc_server_config*, respectively.
1049 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Associated the ID (client or server ID) to the Authentication
1052 Payload to avoid any possibility of forging. Updated the
1053 protocol specification and the code accordingly.
1055 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * The RSA key length is now save to the RsaKey context in the
1058 key generation process in lib/silccrypt/rsa.c. The key length
1059 is now used to figure out the maximum size of the block allowed
1060 to be encrypted/signed.
1062 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1063 is equivalent to the silc_mp_mp2bin but does not allocate any
1066 * Changed silc_mp_mp2bin API to take length argument. If it is
1067 non-zero then the buffer is allocated that large. If zero, then
1068 the size is approximated using silc_mp_sizeinbase, which however
1071 * Created Global RNG API which is global RNG that application can
1072 initialize. After initializing, any routine anywhere in the
1073 code (including library) can use RNG without allocating a new
1074 RNG object. This was done to allow this sort of use of the
1075 RNG in code that has no chance to allocate RNG object. All
1076 applications currently allocate this and many routines in the
1077 library use this. Affected file lib/silccrypt/silcrng.[ch].
1079 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1080 it to use the Global RNG API.
1082 * Defined Authentication Payload into protocol specification that
1083 is used during SILC session to authenticate entities. It is
1084 used for example by client to authenticate itself to the server
1085 to obtain server operator privileges.
1087 Implemented this payload into the lib/silccore/silcauth.[ch].
1088 Implemented also routines for public key based authentication
1089 as the new protocol specification dictates.
1091 Moved definitions of different authentication methods from
1092 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1094 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1095 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1096 silc_pkcs_verify_with_hash functions into the file
1097 lib/silccrypt/silcpkcs.[ch].
1099 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * The client entry's userinfo pointer must be always valid.
1102 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1103 will fail since it requires the userinfo. Now, the userinfo
1104 is allocated as "" if actual userinfo does not exist. Actually,
1105 it must exist and it is totally Ok to drop client connections
1106 that does not announce the userinfo. However, we will make
1107 this workaround for now.
1109 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1110 to return the remote port by socket.
1112 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1115 SILC_SERVER_PENDING_EXEC and added an new macro
1116 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1117 data or when error occurs while processing the pending command.
1119 Added new argument `destructor' into silc_server_command_pending
1120 and to the SilcServerCommandPending object. This destructor is
1121 now called after calling the pending callback or if error occurs
1122 immediately. If error occurs the actual pending callback won't
1123 be called at all - only the destructor. The destructor may be
1124 NULL if destructor is not needed.
1126 All this applies for client library code as well. Similar
1127 changes were made there as well for the pending commands.
1129 In the client, the application must now allocate the
1130 SilcClientCommandContext with the silc_client_command_alloc
1133 * Added reference counter to the SilcServerCommandContext. Added
1134 function silc_server_command_alloc and silc_server_command_dup
1137 Same type of functions added to the client library for the same
1140 * Removed the cmd_ident from IDListData away since it is now
1141 global for all connections. It is the command identifier used
1142 in command sending and with pending commands. The affected file
1145 * Added reference counter to the SilcSocketConnection objecet to
1146 indicate the usage count of the object. The object won't be
1147 freed untill the reference counter hits zero. Currently only
1148 server uses this, and client ignores it. The client must be
1149 set to use this too later. The affected files are
1150 lib/silccore/silcsockconn.[ch]. Added also the function
1151 silc_socket_dup to increase the reference counter.
1153 This was mainly added because it is possible that the socket
1154 is removed underneath of pending command or other async
1155 operation. Now it won't be free'd and proper DISCONNECTING
1156 flags, etc. can be set to avoid sending data to connection that
1157 is not valid anymore.
1159 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1160 the connection. After that it sets SILC_SET_DISCONNECTED.
1161 It is, however, possible that the socket data is not still freed.
1162 The silc_server_packet_process now checks that data is not
1163 read or written to connection that is DISCONNECTED. The socket
1164 get's freed when the reference counter hits zero.
1166 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Changed the client operation API: channel_message operation's
1169 `sender' is now the client entry of the sender, not the nickname
1170 and the `channel' is the channel entry, not the channel name.
1172 In the private_message operation the `sender' is now also the
1173 client entry of the sender not the nickname.
1175 Affected file is lib/silcclient/ops.h and all applications
1176 using the client operations.
1178 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Moved the calling of ops->connect() from connect_to_server_final
1181 into receive_new_id functin since that is the point when the
1182 client is actually allowed to send traffic to network. The
1183 affected file is lib/silcclient/client.c.
1185 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1188 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1189 (if needs broadcasting) instead of broadcasting the packets one
1190 by one which would make a burst in the network traffic.
1192 * Added `broadcast' argument to the functions in silcd/server.[ch]
1193 silc_server_create_new_channel[_with_id] to indicate whether
1194 to send New Channel packet to primary router.
1196 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1198 * Added new function into the silcd/server.[ch] files:
1199 silc_server_create_new_channel_with_id to create new channel with
1200 already existing Channel ID.
1202 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1203 lib/silccore/silcpacket.h. This packet is used t send list of
1204 Set Mode payloads inside one packet. Server uses this to set
1205 the modes for the channels and clients on those channels, that it
1206 announced to the router when it connected to it. The protocol
1207 specification has been updated accordingly.
1209 * The silc_server_new_channel did not handle the packet coming
1210 from normal server as it normally does not send that. However,
1211 when it announces its channels it does send it. Implemented
1212 the support for that.
1214 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1215 into the file lib/silccore/id.h.
1217 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Fixed memory leaks in the functions silc_idlist_del_client,
1220 silc_idlist_del_channel and silc_idlist_del_server in the file
1221 silcd/idlist.c. All of those leaked like a sieve.
1223 * Fixed some small memory leaks in the client's function
1224 silc_client_notify_by_server.
1226 * Added functions into silcd/server.c: silc_server_announce_clients,
1227 silc_server_announce_channels and silc_server_announce_server.
1228 These functions are used by normal and router server to announce
1229 to its primary router about clients, channels and servers (when
1230 router) that we own. This is done after we've connected to the
1233 These functions effectively implements the following packet types:
1234 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1235 and SILC_PACKET_NEW_ID_LIST.
1237 * Added new functions into the silcd/packet_receive.[ch]:
1238 silc_server_new_id_list, silc_server_new_channel_list and
1239 silc_server_new_channel_user_list to handle the incoming
1240 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1242 * Added support of changing Channel ID in the function
1243 silc_server_replace_id. If the server that announces a channel
1244 to the router already exists in the router (with same name but
1245 with different Channel ID), router is responsible to send
1246 Replace ID packet to the server and force the server to change
1247 the Channel ID to the one router has.
1249 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1250 client that the Channel ID has been changed by the router. The
1251 normal server sends this to the client. Client must start using
1252 the new Channel ID as the channel's ID.
1254 Implemented handling of this new type into lib/silcclient/client.c
1255 into the function silc_client_notify_by_server.
1257 * Added new function silc_idlist_replace_channel_id into the files
1258 silcd/idlist.[ch] to replace the Channel ID.
1260 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Call silc_server_command_identify_check always when processing
1263 the IDENTIFY command in silcd/command.c
1265 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1268 send keepalive packets. The packet can be sent by clients,
1269 servers and routers.
1271 Added function silc_socket_set_heartbeat into the file
1272 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1273 If not set, the heartbeat is not performed. The actual
1274 heartbeat is implemented in the low level socket connection
1275 library. However, application is responsible of actually
1278 Added silc_server_send_heartbeat to send the actual heartbeat
1279 packet into silcd/packet_send.[ch]. Server now performs
1280 keepalive with all connections.
1282 * Added silc_task_get_first function into lib/silcutil/silctask.c
1283 to return the timeout task with shortest timeout. There was a bug
1284 in task unregistration that caused problems. TODO has been
1285 updated to include that task system must be rewritten.
1287 * The client library will now resolve the client information when
1288 receiving JOIN notify from server for client that we know but
1289 have incomplete information.
1291 * Rewrote parts of silc_server_remove_from_channels and
1292 silc_server_remove_from_one_channel as they did not remove the
1293 channel in some circumstances even though they should've.
1295 * Encryption problem encountered in server:
1297 The LEAVE command used to send the Channel Key packet to the
1298 router immediately after generating it. However, the code
1299 had earlier sent Remove Channel user packet but not immediately,
1300 ie. it was put to queue. The order of packets in the router
1301 was that Channel Key packet was first and Remove Channel User
1302 packet was second, even though they were encrypted in the
1303 reverse order. For this reason, MAC check failed. Now, this
1304 is fixed by not sending the Channel Key packet immediately but
1305 putting it to queue. However, this is more fundamental problem:
1306 packets that are in queue should actually not be encrypted
1307 because packets that are sent immediately gets encrypted
1308 actually with wrong IV (and thus MAC check fails). So, packets
1309 that are in queue should be encrypted when they are sent to
1310 the wire and not when they put to the queue.
1312 However, the problem is that the current system has not been
1313 designed to work that way. Instead, the packet is encrypted
1314 as soon as possible and left to the queue. The queue is then
1315 just purged into wire. There won't be any fixes for this
1316 any time soon. So, the current semantic for packet sending
1319 o If you send packet to remote host and do not force the send
1320 (the packet will be in queue) then all subsequent packets to the
1321 same remote host must also be put to the queue. Only after the
1322 queue has been purged is it safe again to force the packet
1325 o If you send all packets immediately then it safe to send
1326 any of subsequent packets through the queue, however, after
1327 the first packet is put to queue then any subsequent packets
1328 must also be put to the queue.
1330 Follow these rules and everything works fine.
1332 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added new function silc_server_remove_clients_by_server to
1335 remove all client entries from ID list when the server connection
1336 is lost. In this case it is also important to invalidate all
1337 client entires as they hold the invalid server entry. This
1338 fixes fatal bug when server has lost connection and will reconnect
1341 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Made some sanity checks to silc_server_daemonise like to check
1344 whether the requested user and group actually exists.
1346 * Added sanity check to SKE's silc_ske_responder_finish to check
1347 that the public and private key actually is valid.
1349 * Invalidate the client's nickname when receiving Replace ID
1350 packet and the Client ID is being replaced. This means that the
1351 server will query the nickname if someone needs it (client)
1354 * Sort the ID Cache in client library when the ID Cache data
1355 has changed (needs sorting).
1357 * Do not allow for SILC client to create several connections to
1358 several servers. The client does not support windows right now
1359 and generating multiple connections causes weird behaviour.
1361 Irssi-silc client does support windows and can handle several
1362 connections without problems, see: www.irssi.org and SILC plugin.
1364 * Fixed some places where client was added to the IDList. The
1365 rule of thumb is following (in order to get everything right):
1366 If the client is directly connected local client then the
1367 `connection' argument must be set and `router' argument must be
1368 NULL to silc_idlist_add_client function. If the client is not
1369 directly connected client then the `router' argument must
1370 bet set and the `connection' argument must be NULL to the
1371 silc_idlist_add_client function.
1373 * The funtion silc_server_packet_send_local_channel actually did
1374 not check whether the client was locally connected or not. It
1375 does that now. Fixed a bug related to LEAVE command.
1377 * Fixed Remove Channel User payload parsing bug in server's
1378 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1380 * The server's silc_server_save_channel_key now checks also the
1381 global ID list for the channel as it might not be in the local
1382 list. Fixed a bug related to LEAVE command.
1384 * Is this the end of the [<unknown>] buglet that has been lurking
1385 around for a long time? A little for loop fix in server's
1386 silc_server_command_whois_parse that is used by both IDENTIFY
1387 and WHOIS command. At least, this was a clear bug and a cause
1388 of one type of [<unknown>] buglet.
1390 * WHOIS and IDENTIFY commands call the function
1391 silc_server_command_[whois/identify]_check function even if
1392 we are not router server.
1394 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * Added --with-gmp configuration option. If set the GMP
1397 is always compiled in the SILC source tree. If not set then
1398 it is checked whether the system has the GMP3 installed. If
1399 it has then the GMP won't be compiled (the system's headers
1400 and library is used), if it doesn't have it then the GMP is
1401 compiled in the SILC source tree.
1403 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Changed RSA private exponent generation to what PKCS #1
1406 suggests. We try to find the smallest possible d by doing
1407 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1408 not security fix but optimization.
1410 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Added new config entry [Identity] to fork the server and run
1413 it as specific user and group. A patch from Bostik.
1415 * Imported Dotconf configuration library into lib/dotconf.
1416 This will be used to create the SILC configuration files later.
1417 It will appear in the distsribution after this commit.
1419 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * A big code auditing weekend happening. Auditing code for
1422 obvious mistakes, bugs and errors. Also, removing any code
1425 Removed files for being obsolete:
1427 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1428 inline in the file lib/silcutil/silcbuffer.h)
1430 o lib/silcutil/silcbufutil.c (the header has inline versions)
1432 Changed code to fix possible error conditions:
1434 o The buffer formatting routines now check that the destination
1435 buffer really has enough space to add the data. This applies for
1436 both buffer formatting and unformatting
1437 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1438 unformatting was changed to accomodate following rules:
1439 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1440 sent to the function while XXX_*STRING will not allocate or copy
1441 the data into the buffer. Instead it sets the pointer from the
1442 buffer into the pointer sent as argument (XXX_*STRING used to
1443 require that the pointer must be allocated already). This change
1444 makes this whole thing a bit more consistent and more optimized
1445 (note that the data returned in the unformatting with XXX_*STRING
1446 must not be freed now). The routines return now -1 on error.
1448 o Tried to find all code that use buffer_format and buffer_unformat
1449 and added return value checking to prevent formatting and
1450 especially unformatting errors and possible subsequent fatal
1453 o Changed ske->x and ske->KEY to mallocated pointers in
1454 lib/silcske/silcske.h. Fixed possible data and memory leak.
1456 o Added return value checking to all *_parse* functions. Fixed
1457 many memory leaks as well.
1459 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1460 so that buffer overflows would not happen. All code now also
1461 checks the return value as it can fail.
1463 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Added reconnection support to server if the normal server looses
1466 its connection to the router (for example if router is rebooted).
1467 The server performs normal reconnection strategy implemented
1468 to the server. Affected file silcd/server.c.
1470 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Added new packet type SILC_PACKET_SET_MODE that is used to
1473 distribute the information about changed modes (for clients,
1474 channels and clients channel modes) to all routers in the
1475 network. Updated the protocol specification accordingly.
1477 Added functions into silcd/packet_send.c and
1478 silcd/packet_receive.c: silc_server_send_set_mode,
1479 silc_server_set_mode.
1481 Added new files silcmode.[ch] into lib/silccore that implements
1482 the encoding and decoding of Set Mode Payload. Added new type
1483 SilcSetModePayload. Moved the definitions of different modes
1484 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1486 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Oops, a little mistake in server's connection authentication
1489 protocol. The protocol is not ended with FAILURE but with
1490 SUCCESS if the authentication is Ok. :) Affected file is
1493 * Implemented NICK_CHANGE notify handling in server in the file
1494 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1495 the local clients on the channel. After the changing nickname
1496 in router environment snhould work and the [<unknown>] nickname
1497 should appear no more.
1499 The silc_server_replace_id function that receives the Replace ID
1500 payload now sends the NICK_CHANGE notify type also in the file
1501 silcd/packet_receive.c
1503 * Changed WHOIS and IDENTIFY command to support the maximum amount
1504 of arguments defined in protocol specs (3328 arguments). This
1505 fixed a bug that caused problems when there were more than three
1508 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Added extra parameter, command identifier, to the
1511 silc_client_send_command so that explicit command identifier
1514 Changed that ID list routines uses specific command identifier
1515 when sending WHOIS/IDENTIFY requests to the server so that they
1516 can be identified when the reply comes back.
1518 Affected files lib/silcclient/command.[ch],
1519 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1521 * Added `sender' argument to silc_server_packet_send_to_channel
1522 to indicaet the sender who originally sent the packet to us
1523 that we are now re-sending. Ignored if NULL. Affected file
1524 silcd/packet_send.[ch].
1526 * Added some server statistics support in silcd/server_internal.h
1527 SilcServerStatistics structure and around the server code. Also
1528 send some nice statistics information when client is connecting
1531 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Fixed channel ID decoding in server's JOIN command reply in
1534 silcd/command_reply.c
1536 * Fixed braodcasting of replace ID payload to not to send it if
1537 we are standalone server in silcd/packet_receive.c.
1539 * Fixed all channel message sending routines to not to send
1540 packets to clients that has router set, since they are routed
1541 separately in the same function earlier. Affects file
1542 silcd/packet_send.c and all channel packet sending functions.
1544 * In USERS reply, res_argv[i] are not allocated, the table
1545 is allocated. Thus changed that free the table, not its
1548 * In server's whois_check and identify_check if the client is
1549 locally connected do not send any WHOIS commands - they are not
1552 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Fixed some minor bugs in client when sending WHOIS command. The
1555 arguments was in wrong order.
1557 * Removed statis function add_to_channel from server in
1558 silcd/command.c that was previously used with the joining but
1561 * Tested USERS command in router environment successfully with two
1562 routers, two servers and two clients.
1564 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Reorganized the USERS command and command reply in client library
1567 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1568 When the command is given by user we register a pending command
1569 callback that will reprocess the command after the reply has been
1570 received from the server. When reprocessing the packet we then
1571 display the information. Thus, the USERS information is displayed
1572 now in the command callback instead of in the command reply
1573 callback. The processing of the command is same as previously
1574 when server has sent the command reply in the JOINing process.
1576 * Added to USERS command in silcd/command_reply.c to join the client,
1577 we didn't use to know about, to the channel after we've created
1578 a client entry for it. Also, for clienet we did know already still
1579 check whether it is on the channel or not and add it if not.
1581 * Removed silc_server_command_join_notify as the function and its
1584 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Changed the client's pending command handling to the same as the
1587 server's pending command handling. It is also now possible to
1588 execute command reply functions from other command reply
1589 function as the function callbacks for commands and command
1590 replies are one and same. The pending commands are not static
1591 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1592 in client connection context. Thus, pending commands are server
1593 connection specific as it is convenient.
1595 Changed the function silc_client_command_pending and
1596 silc_client_command_pending_del and added new function
1597 silc_client_command_pending_check. Removed the
1598 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1601 * Added cmd_ident, current command identifier, to the client
1602 connection context in lib/silcclient/client.h to keep track on
1603 command identifiers used in command sending. Client's command reply
1604 function handling now supports the mandatory command identifiers.
1606 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1607 funtions in client to fully support pending command callbacks.
1609 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1610 as one of the arguments to the application in the command reply
1613 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1614 before first releasing SILC but came back. Now it is removed again
1615 and should come back nomore. The FORWARDED flag was used only
1616 by the JOINing procedure by forwarding the command packet to router.
1617 Now, the JOINing procedure has been changed to more generic (due
1618 to various router environment issues) and FORWARDED is not needed
1619 anymore for anything. The protocol specification is yet to be
1622 Now, removed silc_server_packet_forward from server and the flag
1623 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1625 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Renamed NAMES command to USERS command. The NAMES was named that
1628 due to historical reasons. Now it is renamed. Also, rewrote
1629 parts of the USERS command. The nickname list is not sent anymore
1630 by the server. Only Client ID and mode lists are sent in the USERS
1631 command. Changed this also to the protocol specification.
1633 The client now resolves the names and stuff after it receives
1634 the USERS list from the server when joining to the channel.
1636 * WHOIS and IDENTIFY commands has been changed to support multiple
1637 Client ID's per command. One can now search for multiple users
1638 in the network by sending only one WHOIS or IDENTIFY command.
1639 Changed the code and the protocol specifications.
1641 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1642 uses silc_server_command_whois_parse to parse the request. */
1644 * If normal server, do not parse the WHOIS and IDENTIFY requests
1645 before sending it to the router. Saves some time.
1647 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Fixed JOIN command on client library. Wrong number of arguments
1650 used to crash the client.
1652 * Added silc_server_channel_has_global function to check whether
1653 channel has global users or not.
1655 * Added silc_server_channel_has_local function to check whether channel
1656 has locally connected clients on the channel.
1658 * The silc_server_remove_from_one_channel now checks whether the
1659 channel has global users or not after given client was removed from
1660 the channel. It also checks whether the channel has local clients
1661 on the channel anymore. If it does not have then the channel entry
1662 is removed as it is not needed anymore.
1664 * The silc_server_notify now checks on JOIN notify whether the joining
1665 client is one of locally connected or global. If it is global then
1666 the channel has now global users on the channel and that is marked
1667 to the channel entry. Also, it now saves the global client to
1668 global list who is joining and JOINs it to the channel. This is
1669 for normal server, that is.
1671 Changed silc_server_send_notify_on_channel,
1672 silc_server_packet_relay_to_channel and
1673 silc_server_packet_send_to_channel check if we are normal server
1674 and client has router set (ie. global client) do not send the
1675 message to that client, as it is already routed to our router.
1677 * Implemented LEAVE notify type handling in silc_server_notify
1680 * Tested LEAVE command in router environment successfully. Tested
1681 with two routers, two servers and two clients.
1685 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1687 * Implemented SIGNOFF notify type handling in silc_server_notify
1690 * silc_server_remove_id now removes the client entry from all channels
1691 it has joined and thusly sends SIGNOFF notify type.
1693 * Rewrote the NAMES list generation in server by removing two excess
1694 loops. The lists are created now inside one loop.
1696 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * silc_server_remove_channel_user checks now also global list
1699 for channel and client.
1701 * silc_server_new_channel_user checks now both local and global
1702 list for channel and client. Fixed a bug in client id decoding.
1703 Used to decode wrong buffer.
1705 * silc_server_channel_message checks now both local and global
1706 list for channel entry.
1708 * Tested channel joining (hence JOIN) in router environment
1709 successfully. Tested with two routers, two servers and two
1712 * Tested channel message sending in router environment successfully.
1714 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Added silc_server_save_channel_key into server.[ch] to save the
1717 received channel key in Channel Key payload processing. It is
1718 also used in JOIN command reply handling.
1720 Equivalent function silc_client_save_channel_key added into
1721 client.[ch] into client library.
1723 * Changed JOIN command reply to send information whether the channel
1724 was created or not (is existing already) and the channel key
1725 payload. Changed protocol specs accordingly.
1727 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1728 the request was sent by ID and not by nickname. Crashed on
1731 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1734 now correctly save the received data.
1736 * silc_server_free_sock_user_data now notifies routers in the
1737 network about entities leaving the network.
1739 At the same time implemented functions silc_server_remove_id
1740 and silc_server_send_remove_id to receive and send REMOVE_ID
1741 packets. The packet is used to notify routers in the network
1742 about leaving entities. The ID removed will become invalid in
1745 * Added function silc_idlist_del_server into server. Removes and
1746 free's server entry from ID list.
1748 * silc_server_private_message function now checks, if we are router,
1749 that the destination ID really is valid ID, naturally.
1751 * In router when NEW_ID packet is received (for new client) the
1752 hash of the Client ID is saved in the ID Cache but the
1753 client->nickname is set to NULL, instead of putting the hash
1756 IDENTIFY command now also checks that client->nickname must be
1757 valid. If it is not if will request the data from the server who
1758 owns the client. Added new function
1759 silc_server_command_identify_check.
1761 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1762 to set the command to already allocated Command Payload.
1764 * Tested private message sending in router environment with two
1765 routers, two servers and two clients. Fixed minor bugs and now
1768 * Fixed segfault from client's NAMES command. Used to crash if
1771 * Forwarded packets must not be routed even if it is not destined
1772 to the receiver. Changed server code comply with this.
1774 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Added `require_reverse_mapping' boolean value to ServerParams
1777 structure. If TRUE (not default) the server will require that
1778 the connecting host has fully qualified domain name.
1780 If the reverse mapping is not required and hostname could not be
1781 found the IP address is used as hostname.
1783 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Implemented version string checking to both client and server.
1786 The check is incomplete currently due to the abnormal version
1787 strings used in development version of SILC.
1789 * Changed all command functions in server to use the new
1792 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Changed char *data to unsigned char *data in ID Cache system to
1795 support binary data as ID Cache data. Changed code to support
1796 binary data in lib/silccore/idcache.c.
1798 * Renamed silc_server_packet_relay_command_reply to
1799 silc_server_command_reply as it is normal packet receiving
1800 function. Rewrote the function to accept command replys for
1801 servers and not only for clients.
1803 * Mark remote router always as registered server if we are connecting
1804 to it. Otherwise, commands sent by the router to us are ignored.
1806 * All ID List find routines now returns the ID Cache Entry pointer
1807 as well if requested.
1809 * WHOIS command works now in router environment, tested with two
1810 routers, two servers and two clients.
1812 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1813 in router environment (as it is almost equivalent to WHOIS) but
1814 hasn't been tested thoroughly. Added new functions:
1816 silc_server_command_identify_parse
1817 silc_server_command_identify_send_reply
1818 silc_server_command_identify_from_client
1819 silc_server_command_identify_from_server
1821 * Disabled route cache adding because adding two different ID's with
1822 same IP replaces the old cache entry thus giving wrong route.
1823 The entry->router->connection is always the fastest route anyway
1824 so route cache may not be needed. Of course, new routes maybe
1825 established after receiving the ID when the entry->router->connection
1826 might not be anymore the most optimal.
1828 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Add route cache for received ID for fast routing.
1832 * Added silc_server_packet_route to route received packet on router
1833 that is not destined to us.
1835 * Renamed silc_server_get_route to silc_server_route_get.
1837 * Added id_string and id_string_len fields into SilcServer to
1838 include encoded ServerID for fast comparing without excess
1839 encoding of the ID's.
1841 * Cleaned up WHOIS command on server side. Added following static
1844 silc_server_command_whois_parse
1845 silc_server_command_whois_check
1846 silc_server_command_whois_send_reply
1847 silc_server_command_whois_from_client
1848 silc_server_command_whois_from_server
1850 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1851 arguments in command replies. All command functions should be
1852 updated to use this macro.
1854 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Minor typo fixes on command reply handling on server.
1858 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Added silc_server_command_add_to_channel internal routine to add
1861 the client to the channel after router has created the channel and
1862 sent command reply to the server.
1864 * Added generic silc_server_send_command to send any command from
1867 * Use static buffer with ID rendering instead of duplicating data.
1869 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Fixed a channel user mode bug when joining to a channel server gave
1872 everybody channel founder rights, oops.
1874 * We mark ourselves as the router of the incoming server connection
1875 if we are router ourselves. This way we can check in some packet
1876 sending functions whether it is locally connected server. For
1877 incoming router connections we put NULL.
1879 * For router sending packets locally means now always sending the
1880 packet cell wide; to local clients and local servers. For normal
1881 server sending packet locally means sending it to only local
1884 * Fixed the JOIN command to really work in router environment. If the
1885 channel is created it is always created by the router. Router is
1886 also responsible of making the initial joining to the channel,
1887 sending JOIN notify to the sending server and distributing
1888 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1889 does not exist server doesn't do anything else but forward the
1890 command to the router which performs everything.
1892 * Added silc_server_send_channel_key function to send the Channel Key
1895 * Added silc_server_create_channel_key to create new channel key. The
1896 channel key is now re-generated everytime someone joins or leaves
1897 a channel, as protocol dictates. Note: channel->key_len is the
1900 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1903 packet_receive.[ch] to separate packet sending and receiving
1904 routines. The server.[ch] now includes everything else including
1905 actual packet processing (writing and reading data) and other
1908 Renamed silc_server_private_message_send_internal to
1909 silc_server_send_private_message. The routine is still though
1910 used only to relay private messages as server does not send
1911 private messages itself.
1913 Renamed silc_server_new_channel to silc_server_create_new_channel
1914 and added new function sicl_server_new_channel that handles the
1915 incoming New Channel packet. Added also new sending function
1916 silc_server_send_new_channel to send New Channel Payload.
1918 * Added new function silc_server_notify to process incoming notify
1919 packet to the server/router. Server may then relay the notify
1920 to clients if needed.
1922 * Added new function silc_server_new_channel_user to process incoming
1923 New Channel User packet. Router will redistribute the packet and
1924 send JOIN notify to its local clients and locally connected servers
1925 if needed. Normal server will send JOIN notify to its local client
1926 on same channel when received this packet. Added also corresponding
1927 sending function silc_server_send_new_channel_user to sent the
1930 * Added boolean route argument to send_notif_to_channel and
1931 packet_send_to_channel functions to attempt to route the packet
1932 if it is TRUE and send only locally if it is FALSE.
1934 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * silc_server_replace_id now broadcasts the received replace ID
1937 packet if it is not broadcast packet already. The router must
1938 broadcast to inform other routers about changed ID.
1940 * Added backpointer to server's router into SilcServer context in
1941 silcd/server_internal.h.
1943 * Fixed silc_server_packet_broadcast to send correct broadcast
1946 * The channel key is now distributed to the local client as soon
1947 as it is received from the router (in router environment) so that
1948 no other packet may be sent for the channel until client has
1951 * silc_server_remove_channel_user now broadcasts the received
1952 Remove Channel User packet if it is not broadcast packet already.
1953 The router must broadcast to inform other routers about removed
1956 * Added users field into SilcPacketContext that is a reference count
1957 of the context. One can increase the reference count by calling
1958 silc_packet_context_dup which is now changed to just increase the
1959 reference count instead of duplicating the data. The reference
1960 count is decresed by calling silc_packet_context_free that will
1961 free the data after the reference count hits zero.
1963 For now on the packet context and everything allocated into it
1964 (including the raw packet from network) must be freed by calling
1965 the new silc_packet_context_free function. Added also new function
1966 silc_packet_context_alloc that must be used now to allocate the
1967 context. This also means that if a routine is asynchronous from
1968 silc_[client/server]_packet_parse_type the packet context must
1969 be duplicated by calling silc_packet_context_dup. Otherwise it
1970 gets free'd after silc_[client/server]_packet_parse_type returns.
1971 Also, one must remember that if packet is duplicated then its
1972 reference count must be decresed by calling the free function as
1973 many times as it was duplicated.
1975 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1976 from both client and server.
1978 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Made joining to a channel working in router environment.
1982 * Cleaned up JOIN command on server side and create function
1983 silc_server_command_join_channel internal routine to make the
1986 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Changed silc_command_pending list to SilcDList. Also, added
1989 `ident' field to SilcServerCommandPending structure to identify
1990 the reply and to call correct callback.
1992 Added silc_server_command_pending_check function to replace the
1993 corresnponding macro. The silc_command_pending list is not
1996 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1997 to set identifier to previously allocated Command Payload. It
1998 is used to set identifier for command when resending Command
2001 * Added silc_command_payload_encode_payload to encode Command
2002 Payload buffer from SilcCommandPayload structure.
2004 * Added silc_argument_payload_encode_payload to encode Argument
2005 payload buffer from SilcArgumentPayload structure.
2007 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Changed WHOIS command to support router connection on server side.
2010 The whois request is always sent to router unless the server is
2011 standalone server. After server has received the reply from the
2012 router will it send the reply to the client.
2014 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2015 broadcast received broadcast packet. The function is used only
2016 by router. The broadcast packet is always sent to the router's
2019 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2020 render given ID to printable string, for log files for example.
2022 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Made basic router to router connections working. At least they
2025 can now connect to each other but nothing really works the way
2026 they are supposed - yet.
2028 * Added new initiator token to RouterConnection configuration
2029 file in silcd/serverconfig.[ch]. It is used to tell whether we
2030 are the initiator to the remote router or whether we'll expect
2031 the other end to connect.
2033 * Moved registering of listener task to silc_server_init, hence
2034 the server starts listenning as soon as it is run, even if it
2035 does not have connections to other routers. Let's see how well
2038 * Changed default connection retry timeouts for more suitable in
2041 * Removed cipher and such arguments from silc_idlist_add_client
2042 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2043 Added new function silc_idlist_add_data to add the keys and stuff
2046 * Added SilcIDListData structure and added it to SilcClientEntry
2047 and SilcServerEntry as their first field in the structure. This
2048 way we can explicitly cast the ID entries to the SilcIDListData
2049 structure and get common data for the entries. In past, we had
2050 to first check what type of connection it is and then cast it to
2051 correct ID entry type. Now, we can directly cast the opaque
2052 pointer to the SilcIDListData (no matter what ID entry it actually
2053 is) and get the data needed.
2055 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2058 in some circumstances even if threre were timeout tasks, though not
2059 IO tasks, but tasks anyway. Now fixed.
2061 * Defined SilcServerConnection structure to hold connection specific
2062 stuff about directly connected servers and routers. The definition
2063 is currently in silcd/server_internal.h. I thought about having
2064 a bit more important role fro this struct but for now it is used
2065 only when connecting to other server (or router actually).
2067 * Added connecting retry support in server when connecting to
2068 router(s). The retry feature implement exponential backoff
2069 algorithm. Also, added SilcServerParams structure to hold default
2070 parameters for server. For now, it include these retry settings
2071 and are hard coded. After server is moded to be as Silc Server
2072 Library this structure will be more important.
2074 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Changed client librarys channel->clients table to SilcList and
2077 changed code accordingly.
2079 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Changed client's channel table to SilcList and changed code
2082 accordingly. Also changed SilcChannelClientEntry to include back-
2083 pointer to the channel so that client entry can use that structure
2084 as list as well and we have fast cross-reference to the channel.
2085 This change dramatically decreased the complexity of channel
2086 handling with client entry and vice versa (removed one extra
2087 loop when searching for channel entry from many functions).
2089 * Changed server->sim from table to SilcDList and changed code
2092 * NAMES command can now be used from user interface. It will show
2093 the user list on the channel, neatly.
2095 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2096 Code now saves realname of the user if it becomes available.
2098 * Renamed configure.in to configure.in.pre and made ./prepare
2099 script to automatically add correct version string to
2100 configure.in which it creates from configure.in.pre.
2102 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * NAMES command reply now shows users mode with the nickname when
2107 * Moved silc_client_ch[u]mode[_char] functions from
2108 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2109 place sucks, they are utility functions and should be in some
2112 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2114 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2117 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Added TRQ (efficient deque and list library) into lib/trq. This is
2122 a very good list library that is currently used in the SILC. Defined
2123 SilcList API over the library because I didn't like the API very
2124 much. See lib/trq/silclist.h for the API and examples of how to
2125 use the API. Fixed various places in the code to use the new
2126 SilcList API. The SilcList is meant for lists that has a structure
2127 already defined as a list. It is not suitable to add just some
2128 context to the list (in TRQ, the context is the list actually).
2130 So, I defined SilcDList that can be used for the purpose where
2131 predefined list structure does not exit. This can be used as
2132 such list. Now some context just can be added to the SilcDList.
2133 Currently this list is not used in the SILC just yet, though there
2134 are a lot places where this can replace dynamically allocated
2135 tables and I will fix these places, later, to use SilcDList.
2136 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2137 and use TRQ internally).
2139 Also fixed some annoying warning messages that the original TRQ
2140 code generated. Also minor changes to TRQ's Makefile.in.
2142 * Added support for querying by Client ID to both WHOIS and
2143 IDENTIFY commands into server, as required by the protocol.
2145 * Removed method function pointers from SilcBuffer structure. They
2146 weren't used to anything and just increased the context size for
2147 no good reason. This change also made silc_buffer_alloc and
2148 silc_buffer_free functions inline functions.
2150 * Disabled command flooding detection support until it's fixed so
2151 that it accepts commands in but does not execute them more than once
2154 * Added silc_net_localhost(), to return local hostname, into
2155 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2156 that must be initialized before calling silc_client_init.
2158 * Added new function: silc_server_send_notify_on_channels to send
2159 notify messages to all channels client has joined. It is assured
2160 that the message is sent only once per client.
2162 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2163 lib/silcutil/silcutil.[ch] as silc_format function. The new
2164 function is generic and is used by server as well, not only by
2165 the logging routines.
2167 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2168 the provided version string was not acceptable. Added new function:
2169 silc_ske_check_version into lib/silcske/silcske.h. The function
2170 must be implemented by the application (client or server) and it
2171 does not reside in the SKE library. The function checks the version
2172 string remote end sent.
2174 * Added back pointers (to opaque context and to SilcSocketConnection)
2175 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2177 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2178 duplicate packet context structure.
2180 * Changed `notify' client operation to send same arguments as client
2181 receives from server except for ID's. ID's are mapped to correct
2182 ID entry and that is returned. Also, if channel entry is not sent
2183 by server but the notify is for channel the channel entry is sent
2184 to application (otherwise application doesn't know that it is for
2185 channel (library gets it from packet's Destination ID)).
2187 * Added silc_client_remove_from_channels into client library to
2188 remove a client from all channels it has joined to. Used when
2189 received SIGNOFF notify from server. Added also new function
2190 silc_client_replace_from_channels to replace old ID entry with
2191 new ID entry on all channels. Used when received NICK_CHANGE
2194 * Fixed ID Cache list handling in silc_idlist_get_client in
2195 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2196 to get (or query) client by ID.
2198 * Updated TODO list.
2200 * Added connection authentication status message defined by the
2201 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2202 support for these into the code in client and server side.
2204 * Added generic function silc_client_send_command to send any command
2205 with variable argument list. Application should use this function
2206 to send commands if the command functions provided by the library
2207 does not suite for the application's user interface needs.
2209 * Added new `failure' client operation. Application is notified about
2210 received failure packet if client is executing a protocol. In this
2211 case the protocol's execution has failed.
2213 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2214 is required by the protocol.
2216 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2217 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2220 * Added status flag to SilcSKE object to indicate realtime status
2221 of the SKE protocol.
2223 * Application receives now exactly same command reply arguments as
2224 the library receives from server. However, if ID is received the
2225 corresponding ID entry is returned to the application (eg. Client
2226 ID is mapped to correct SilcClientEntry entry and that is returned).
2227 Changed command_reply client operation due to this change.
2229 * Changed all ID's in commands and in command replys as ID Payloads.
2230 Change affected both client and server side codes.
2232 All ID's sent in SILC network (with execption of ID's in SILC
2233 Packet header) are sent in ID Payload to support variable length
2236 * Server now notifies nick changes and notifies all clients on
2237 the channels about the new nickname (about the new Client ID,
2240 * Implemented CMODE command to change channel modes. Supports all
2241 channel modes defined by the protocol specs except ban and invite
2242 lists. (Also, private channel key mode is supported but support for
2243 setting private channel key in client is missing, thus, this mode
2244 has no effect on client side (except that server requires that the
2245 client uses private channel key and normal channel traffic does not
2248 Also, invite mode works per se, but INVITE command does not work
2249 yet correctly, so you can set channel as invite only channel but
2250 inviting clients to the channel does not work (it is yet to be
2251 thought what's the best way to do it).
2253 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2254 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2255 Implemented CUMODE command to change user's mode on the channel.
2256 Supports all modes defined by the protocol specs.
2258 * Added NAMES command reply to return users modes on the channel.
2260 * Removed unnecessary and slow ciphers from lib/silccrypt.
2262 * Set SO_KEEPALIVE option to connection sockets by default.
2264 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2266 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2267 redefined the Notify Payload into protocol specs.
2269 * Added silc_id_payload_parse_id to get ID directly from raw
2272 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2275 accept searching by Client ID as well.
2277 * Added support for LEAVE and SIGNOFF notify types in client library.
2279 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2280 to parse ID Payload from raw data.
2282 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Added flags parameter into silc_ske_assemble_security_properties
2285 function in lib/silcske/silcske.[ch].
2287 * Changed notify client operation to fit better for notify messages
2288 sent by server. The notify payload received from server is now
2289 passed to the application (after parsing it to SilcNotifyPayload).
2290 It is application's responsibility to retrieve the arguments
2291 from the payload and show the message the way it wants. The message
2292 sent by server is implementation specific.
2294 * Changed public keys to comply with the protocol specification.
2295 Old public keys are not supported anymore and are not compatible.
2297 * Removed nickname from Channel Payload as the latest draft removed
2298 it. The client must resolve the nickname from the NAMES command
2299 reply received when it joined the channel.
2301 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2303 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Fixed some errors in protocol specification drafts.
2307 * Created lib/silccore/silcnotify.c to implement Notify Payload
2308 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2309 generic payloads described by protocol specifications. The file
2310 includes implementations for ID Payload and Argument Payload.
2312 * Changed Command Payload implementation to use the new Argument
2313 Payload. Changed command_xxxx_payload to command_payload_xxxx
2314 to comply with SILC coding conventions.
2316 * Added suppport for Argument Payload handling in Notify Payload
2317 implementation as protocol requires it. Added the new support
2318 into server and client lib as well.
2320 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added support for multiple nicknames on same channel. [n] is
2323 added locally to the nickname if there are more than one same
2324 nicknames on the channel.
2326 * Server now sends all nicknames that matched WHOIS request.
2327 Client also shows the list received from server.
2329 * Added TOPIC command to client side. User can now set and show
2330 current topic on channel.
2332 * Added MOTD command to client and server. Also, server sends the
2333 motd when client connects to the server.
2335 * Changed version strings to comply ISO 8601.
2337 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2339 * Fixed protocol error handling in client library. It should now
2340 cope even if the SKE fails for some reason.
2342 * Made new protocol specification drafts for submitting to IETF.
2344 * Implemented TOPIC command to server in silcd/command.c.
2346 * Added two new notify types into lib/silccore/silcnotify.h:
2347 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2348 notify nickname change and topic setting/change on a channel.
2350 * API change of command_reply operation in client library. The
2351 application gets now the status type received from server as well.
2353 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2357 * Cras fixed and optimized the packet handling even further and
2358 it should work now. Minor change to the prototype of function
2359 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2361 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Added new function into lib/silcutil/silcschedule.[ch]:
2364 silc_schedule_with_fd to select() a specified fd. The function
2365 returns after timeout expires or data arrives or goes. The
2366 function is used by packet routines to wait that all data is
2367 received from network.
2369 * Fixed data reading from network in lib/silccore/silcpacket.c.
2370 The code now assures that all data is read from the fd and then
2371 continues packet processing. This was a bug fix since the code
2372 used to drop some data in some circumstances.
2374 * Added new function into lib/silcclient/client.[ch]:
2375 silc_client_start_key_exchange to start key exchange after
2376 connection has been established to server. The code internally
2377 now uses this funtion but its main purpose was to provide it
2378 for applications that perform their own connecting. After
2379 application has created a connection it merely calls this
2380 function to start the key exchange between client and server.
2381 The library takes care of everything else after that.
2383 Updated also lib/silcclient/README to explain the usage of
2386 * Do not send to application information that connection has
2387 been established. Application gets notified it by connect
2390 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Applied cras's patch to add silc_schedule_one function. The
2393 function runs scheduler once and returns.
2395 * Fixed the scheduler after cras messed it up. The timeout
2396 handling works now as it's supposed to work.
2398 * Added into lib/silccore/ silcnotify.h to include notify
2399 message types support. Changed silc_server_send_notify*
2400 functions, in server.[ch], to support those new notify types.
2401 Added the support for the notify types into client library,
2402 as well. Added new notify client operation into ops.h in
2405 * Changed silc_server_packet_send_to_channel to send normal
2406 packets instead of just channel message packets. The function
2407 is now used to send the notify packets to channels. It is not
2408 used to send channel message packets anymore, as server never
2411 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2412 va_arg()s as it seems to require it nowadays. I guess, if SILC
2413 is compiled with older va_arg() the new code should work anyway.
2415 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Splitted core library. Core library (lib/silccore) includes
2418 now only SILC protocol specific core (and common) components.
2419 Created new utility library (lib/silcutil) that includes more
2420 generic purpose stuff. The stuff for util library was taken
2421 from the old core library. This was minor and easy split.
2423 * Created SILC Client Library (lib/silcclient) that includes
2424 implementation of the SILC client without user interface. This
2425 was major move from silc/ directory. The code has been changed
2426 so that it is transparent towards the user interface. The
2427 silc/ directory includes now the same user interface as before
2428 and it uses the new client library. Read lib/silcclient/README.
2429 Basicly, the client library performs everything else related
2430 to SILC except user interface handling. Also, configuration
2431 files are considered to be part of user interface and library
2432 does not handle them.
2434 This change also changed a lot of structures, function naming etc.
2435 Most important change was that SilcClientWindow object was
2436 renamed to SilcClientConnection in the client library. Created
2437 also new file lib/silcclient/ops.h. Also added new files
2438 silc/local_command.[ch] and silc/client_ops.[ch].
2440 All these changes were made to make it easier for user interface
2441 designers to create what ever user interface for the SILC client
2444 It is also expected that the server will be moved to lib
2445 directory as well and SILC Server Library will be created;
2446 sometimes in the future.
2448 * Removed Local commands from lib/silccore/silccommand.h as
2449 they are application specific and new client library does not
2450 handle any of those anymore.
2452 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2453 old client implementation in silc/.
2455 * Added support for callback functions in SILC_LOG_* macros.
2456 Application can now set its own callbacks that will be called
2457 instead of using the default functions that will always print
2458 the debug messages to stderr (or stdout). Also, debugging can
2459 now be disabled by setting silc_debug to FALSE and re-enabled by
2460 setting it to TRUE. Note, that logging will still work even
2461 if debugging is disabled.
2463 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2464 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2465 silc_log_reset_debug_callbacks.
2467 * To enable debugging in silc client one must give now -d
2468 option on command line.
2470 * Changed silc_schedule_init to automatically allocate task queues
2471 if they are not allocated before calling it.
2473 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added GMP 3.1 into math library.
2477 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2480 a channel in SILC network. The packet is used by servers and
2481 routers to notify other routers that user has left a channel.
2482 This little feature was missing until now. Added the feature
2483 to protocol specification as well.
2485 Added functions: silc_server_send_remove_channel_user and
2486 silc_server_remove_channel_user into server.[ch].
2488 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2489 lib/silccore/silcpacket.h. However, they are not implemented
2492 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Fixed joining to a channel and sending channel messages
2495 between server and router. The channel message sending should
2496 now work inside a cell.
2498 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Fixed the private message sending between server and router.
2501 The private message sending should now work inside a cell.
2503 * Added silc_server_replace_id into server.[ch] to replace
2504 existing ID in the SILC network.
2506 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2507 and silc_idlist_replace_server_id into idlist.[ch] in server.
2509 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Fixed the server to server connections. Server can again now
2512 connect to router. Router to router connections probably does
2515 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added dynamic protocol registering support. Now protocols can
2518 registered and unregistered on the fly. Patch by cras.
2520 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Added lib/contrib directory to hold routines that some platforms
2523 don't have but are needed by SILC.
2525 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2526 into lin/contrib to provide getopt() and getopt_long() for
2527 those who don't have it.
2529 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Added AWAY command to client. When away message is set and
2532 client receives a private message packet the client automatically
2533 replies to the sender with the away message.
2535 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2536 bug seemed to be the cause of recent problems when compiling
2539 * Added version detection support to SKE protocol specification
2540 and added the new changes to the SKE implementation as well.
2541 There were other minor changes in the SKE protocol as well.
2543 Many changes in lib/silcske/silcske.[ch] and in
2544 lib/silcske/payload.[ch].
2546 * Added ^U functionality, clear input line. Patch from cras.
2548 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Mainly small bugfixes on core library. Fixed some debugging
2551 logging and buffer overflow in silclog.c.
2553 * Updated config.sub and config.guess on the distribution tree.
2555 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Added command lagging support in server. Client may execute
2558 commands now only once in two seconds.
2560 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Optimized packet reception. MAC computation and checking is now
2563 also more optimized. A lot previously duplicated code is now
2564 used as generic by both client and server.
2566 * Fixed key pair generation in clientutil.c
2568 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Added into lib/silccore/silcbufutil.[ch] new function;
2571 silc_buffer_realloc.
2573 * Moved generic packet sending/encryption functions to
2574 lib/silccore/silcpacket.[ch] from client and server. Some
2575 rewriting of the functions.
2577 * Moved all generic packet reception/decryption functions to
2578 lib/silccore/silcpacket.[ch] from client and server. The
2579 packet processing is now much cleaner in both client and server.
2580 These were major changes in both client and server.
2582 * Created many common functions in server to do packet sending.
2583 Previously code were duplicated a lot, this has been removed
2586 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Rewrote major parts of the ID cache system. Don't know
2589 whether it is better now or not but at least the API is more
2592 * Major rewrite on ID cache stuff on client because of the ID
2593 cache API changes. Added idlist.c to client.
2595 * Also major rewrite on ID cache stuff on server as well.
2596 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2597 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2598 in hand, instead they are all put into the ID cache system now.
2599 All server_idlist_* routines uses ID cache now instead of
2600 traversing its own lists (those lists does not exist anymore).
2601 SilcIDList though still exists. Also, SilcXXXEntry's are
2604 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Finally made the SKE implementation compliant to the protocol
2607 specification. All mp integers are now binary encoded as
2608 opposed being HEX encoded.
2610 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2613 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2614 functions: silc_[encode/decode]_pem. Also added function
2615 silc_encode_pem_file to PEM encode with newlines ('\n') for
2618 * SILC public keys are now encoded either PEM or binary. Same
2619 option is for private keys as well. By default private keys
2620 are binary encoded and public keys PEM encoded. Silly HEX
2621 encoding were removed.
2623 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2624 function to create fingerprints.
2626 * Fixed a bug in SHA1; does not change the original data anymore.
2628 * Partly implemented INFO command on client and server side.
2629 Fixed CLEAR command. Changes to SERVER command; show current
2630 server(s) when giving command without arguments. Added
2631 VERSION command to client.
2633 * Added check to server that unregistered connections cannot
2634 execute commands (unless it is specificly allowed).
2636 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Fixed screen refresh.
2640 * Fixed channel joining bug from client. On some circumstances
2641 client tried to join to a channel it had already joined.
2643 * Added public key verification process into client's protocol.c.
2644 The client now verifies the public key from user and saves
2645 it into ~./silc/serverkeys/ directory.
2647 Added into: clientutil.[ch]: silc_client_verify_server_key.
2649 * Changed SKE protocol's silc_ske_initiator_finish function
2650 to accept callback function that verifies the received public
2651 key. Removed old silc_ske_verify_public_key function.
2653 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2656 silc_pkcs_private_key[_data]_set.
2658 * Made the password and public authentication more cleaner in
2659 server's protocol.c.
2661 * Removed historic and obsolete protocol `channel_auth' from
2662 both client and server.
2664 * Removed wrong way of sending command status messages from
2665 server to client in server's command.c. The old way violated
2666 protocol specification.
2668 Changes to silccore/silccommand.[ch]: removed
2669 silc_command_encode_status_payload -> not needed anymore,
2670 changed silc_command_encode_payload_va to accept extra
2671 argument on variable argument list. The argument type must
2672 now be provided to the function. Also, added new function:
2673 silc_command_encode_reply_payload_va which is same as
2674 normal command_encode_payload_va except command status type
2675 is provided as extra argument.
2677 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Added ~./silc directory handling. The directory includes the
2680 public and private keys for the client.
2682 Added silc_client_check_silc_dir, silc_client_create_identifier
2683 and silc_client_load_keys.
2685 * Implemented SILC protocol compliant public key. Added public
2686 and private key saving to and loading from files.
2688 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2689 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2690 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2691 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2692 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2694 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2695 silc_pkcs_load_[public/private]_key.
2697 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added silc_server_get_route (route.[ch]) to get connection
2700 data for the fastest route for given ID.
2702 * Implemented INVITE command on client and server. The command
2703 were re-defined in the SILC Protocol Specification and the
2704 implementation now complies with the specification.
2706 * Implemented PING command on client and server.
2708 * Implemented NAMES command on client and server. The server side
2709 supports currently only normal server not router server yet.
2710 Some changes to NAMES definition in SILC protocol specification.
2712 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Implemented LEAVE command on client and server.
2716 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2717 again. This change was made to the protocol as well. Server
2718 should not violate the protocol specification anymore.
2720 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2723 was tested. SOCKS4 was not but should work anyway.
