3 * Show the version of the remote client (or server) when connecting
4 to the server. It is logged to the log file. Affected file
7 * Fixed the KILLED notify handling in the client library. The
8 client must be removed from all channels when receiving the
11 Also, do not remove the client entry when giving the KILL
12 command but when the KILLED notify is received.
14 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

17 notify between routers.
19 * Implemented the INVITE command correctly to the server.
21 * Implemented the INVITE notify type handling in the server.
23 * Implemented the INVITE command to the client library and on the
26 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Added function silc_server_get_client_resolve to find the
29 client entry by ID from all ID lists and then resolve it
30 (using WHOIS) if it cannot be found. Affected file is
33 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Implemented the BAN command to the client library.
37 * The JOIN command in the server now checks the invite list
40 * Changed the silc_command_reply_payload_encode_va and the
41 silc_command_payload_encode_va to support that if argument is
42 NULL it ignores and checks the next argument. Affected file
43 lib/silccore/silccommand.c.
45 * Added silc_server_send_notify_ban to send the BAN notify
48 * Chaned the silc_notify_payload_encode to support that if
49 argument is NULL it ignores and checks the next argument.
50 Affected file lib/silccore/silcnotify.c.
52 * Tested ban lists in router environment successfully.
54 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

62 Affected files lib/silcutil/silcutil.[ch].
64 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * Redefined parts of the SilcChannelEntry in the server to support
67 the new ban and invite lists.
69 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
71 * Redefined the INVITE command. The same command can be used to
72 invite individuals to the channel but also to manage the invite
73 list of the channel (to add to and remove from the invite list).
74 Updated the protocol specs.
76 * Added new command SILC_COMMAND_BAN that can be used to manage
77 the ban list of the channel. Updated the protocol specs.
79 * Removed the channel modes: the SILC_CMODE_BAN and the
80 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
81 in the CMODE command. The equivalent features are now available
82 using INVITE and BAN commands. Updated the protocol specs.
84 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
85 in the network about change in the current ban list. The notify
86 type is not used by the client.
88 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
89 support the invite lists.
91 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * Added new function silc_string_regexify that converts string
94 including wildcard characters into regex string that can
95 be used by the GNU regex library. Added into the file
96 lib/silcutil/silcutil.[ch].
98 Added silc_string_regex_combine to combine to regex strings
99 into one so that they can be used as one regex string by
100 the GNU regex library. Added into the file
101 lib/silcutil/silcutil.[ch].
103 Added silc_string_regex_match to match two strings. It returns
104 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
106 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Imported GNU regex to the soruce tree into lib/contrib.
109 Fixed some compiler warning from the regex.c.
111 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Fixed MOTD command in the server to work in router environment.
115 * Fixed the MOTD command in the client library to support
116 the server argument in the command.
118 * Added `nickname_len' argument to the silc_idlist_add_client
119 in the server, as the `nickname' argument may be binary data
122 * Added silc_idlist_get_channels to return all channels from
125 * Implemented LIST command to the server. Affected file is
128 * Implemented the LIST command to the client library and on the
131 * Added [<user count>] argument to the LIST command reply.
132 With private channels the user count is not shown.
134 * Updated TODO and README.
136 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * The client entry's data.registered must be TRUE even with
139 global client entry on global client list. The data.registered
140 is used to check whether the client is anymore in the network,
141 for example with WHOWAS command so it must be valid.
143 * Fixed the WHOWAS command in the server. It now actually works
144 in router environment. Added function into silcd/command_reply.c
145 silc_server_command_reply_whowas_save.
147 * Added silc_idlist_purge function to the silcd/idlist.c
148 to periodically purge the ID Cache.
150 * Fixed INFO command in the server. It works now in router
151 environment. Added <server name> argument to the INFO command
152 reply. Updated the protocol specs.
154 * Fixed minor bug in silc_idcache_purge to not purge if the
155 expire value is zero.
157 * Fixed various bugs in WHOIS and IDENTIFY command handling as
158 they were buggy because of the WHOWAS information.
160 * Fixed local command MSG to handle the async resolving of
161 the remote client properly. It used to fail the first MSG.
162 Affected file silc/local_command.c.
164 * Added `data_len' field to SilcIDCache context.
166 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Update TODO. Todo in commands in the server.
170 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
173 used by routers as broadcast packet to inform other routers
174 about the changed user mode.
176 Implemented the notify handling in the server. Affected file is
177 silcd/packet_receive.c. Added the function
178 silc_server_send_notify_umode to the silcd/packet_send.[ch].
180 * Added new generic Channel Payload and deprecated the New Channel
181 Payload. The New Channel Payload is now the generic Channel
184 * Added new argument `mode' to the silc_server_send_new_channel
185 as it is required in the Channel Payload now.
187 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
188 and created a new and real SilChannelPayload to represent the
189 new generic Channel Payload. Implemented the encode/decode
190 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
192 * Added silc_server_get_client_channel_list to return the list
193 of channels the client has joined for WHOIS command reply.
194 Affected file silcd/server.[ch].
196 * Implemented the channel list sending in the WHOIS command reply
197 in server and in the client.
199 Implemented the channel list displaying on the user interface
200 as well. Affected file silc/client_ops.c.
202 * Added silc_channel_payload_parse_list to parse list of Channel
203 Payloads. It returns SilcDList list of SilcChannelPayloads.
204 Client for example can use this function to parse the list of
205 channels it receives in the WHOIS command reply. The caller
206 must free the list by calling silc_channel_payload_list_free.
207 Affected files lib/silccore/silcchannel.[ch].
209 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Added one new argument <user mode> to the WHOIS command reply
212 to return the mode of the user in SILC. Updated the protocol
215 Implemented it to the server and client.
217 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Fixed the mode printing on the user interface on joining.
220 Affected file silc/client_ops.c.
222 * Implemented the UMODE command and user modes in general to the
223 client library and to the user interface.
225 * Implemented the UMODE command to the server.
227 * The server now sends UNKNOWN_COMMAND error status if client sends
228 unknown command. Affected file silcd/command.c.
230 * All server commands now handle the command identifier the right
231 way when sending the command reply to the client. The client can
232 use to identify the command replies with the identifier.
234 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Added silc_server_get_client_route to resolve the route to
237 the client indicated by the client ID. Affected file is
240 * Added silc_server_relay_packet as general function to relay
241 packet to arbitrary destination. This deprecates functions
242 like _send_private_message_key, _relay_notify etc. Affected
243 file is silcd/packet_send.[ch].
245 Removed silc_server_send_key_agreement,
246 silc_server_send_private_message_key and
247 silc_server_packet_relay_notify functions from the file
248 silcd/packet_send.[ch].
252 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
253 server. Affected file silcd/packet_receive.[ch].
255 * Implemented the KILL command to the client. Implemented the
256 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
257 Affected files lib/silcclient/command[_reply].c and
258 lib/silcclient/client_notify.c. Implemented the KILL notify
259 printing in the user inteface.
261 * Fixed a lot silc_parse_nick memory leaks from the client
262 library in the file lib/silcclient/command.c.
264 * Changed the silc_server_send_notify_on_channels's `sender'
265 argument from SilcSocketConnection to SilcClientEntry to
266 check the sender as entry and not as connection object and not
267 to send to the client provided as argument. The affected file
268 is silcd/packet_send.[ch].
270 * The notify packets that are destined directly to the client used
271 to not to be processed by the server. Now changed that and the
272 server processes all notify packets. After relaying the packet
273 to the client the notify packet is processed in the server.
275 * The silc_server_free_client_data now checks whether there is
276 pending outgoing traffic for the client and purges the data to
277 the network before removing the client entry.
279 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
281 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
282 an client is killed from the SILC Network. Updated the protocol
285 Added new function silc_server_send_notify_killed to the
286 silcd/packet_send.[ch].
288 * Added function silc_server_packet_relay_notify to relay notify
289 packets that are destined directly to a client. In this case
290 the server does not process the notify packets but merely relays
291 it to the client. Affected file silcd/packet_send.[ch].
293 Added also silc_server_packet_process_relay_notify to check
294 whereto relay the notify. Affected file is
295 silcd/packet_receive.[ch].
297 * Implemented the KILL command to the server.
301 * Added the backup schema desgined last fall to the protocol
302 specs for everyone to see. The specification is in the
303 *-spec-xx.txt draft and the packet type definitions for the
304 backup routers is in *-pp-xx.txt draft. Thusly, added also
305 new packet type SILC_PACKET_CELL_ROUTERS.
307 * A big security problem in the implementation discovered. The
308 signoff of an client did not cause new channel key generation
309 which it of course should've done. The channel keys must be
310 always re-generated when client leaves (or signoffs) the channel.
311 The silc_server_remove_from_channels funtion now handles
312 the channel key re-generation.
314 * Added `sender' argument to the silc_server_send_notify_on_channels
315 to not to send the client provided as argument. Affected file
316 silcd/packet_send.[ch].
318 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Implemented OPER and SILCOPER commands into the server and
323 * Added silc_auth_verify and silc_auth_verify_data to verify
324 the authentication directly from the authentication payload.
325 It supports verifying both passphrase and public key based
326 authentication. Affected file lib/silccore/silcauth.[ch].
328 * Added `hash' field to the SilcIDListData structure. It is the
329 hash negotiated in the SKE protocol. Affected file is
332 * Slight redesigning of the SilcAuthPayload handling routines.
333 Do not send SilcPKCS but SilcPublicKey as argument.
335 * Implemented the public key authentication support to the
336 serverconfig. The public key is loaded fromthe provided path
337 and saved as authentication data to void * pointer. Thus,
338 changed the unsigned char *auth_data to void *auth_data;
340 * Fixed SHUTDOWN command to send the reply before the server
341 is shutdown. :) Affected file silcd/command.c.
343 * Fixed fatal bug in CONNECT command. The hostname was invalid
344 memory and server crashed. Affected file silcd/command.c.
346 * Fixed fatal bug in CLOSE command. The server_entry became
347 invalid but was referenced later in the command. Affected file
350 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Fixed fatal bug in failure packet handling. Server ignored
353 the failure and thus crashed when it came.
357 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
360 that the command may be executed only once in (about) 2 seconds.
361 The old SILC_CF_LAG flag is same but allows command bursts up
362 to five before limiting.
364 Added the support for CF_LAG and CF_LAG_STRICT flags to the
365 server code. Various commands now includes the CF_LAG_STRICT
366 flag to disallow any kind of miss-use of the command.
368 * Fixed the silc_buffer_unformat to not to allocate any data
369 if the length of the data is zero. It used to allocate the
370 length + 1. Affected file lib/silcutil/silcbuffmt.c.
372 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Changed the format of AdminConnection configuration section
375 in the server. Added username of the admin to the format.
376 Affected files silcd/serverconfig.[ch].
378 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
379 to return admin configuration data by host, username and/or
382 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Implemented WHOWAS command to the server. Added the functions:
386 silc_server_command_whowas_parse,
387 silc_server_command_whowas_send_reply,
388 silc_server_command_whowas_from_client and
389 silc_server_command_whowas_from_server
391 * Added <Client ID> argument to the WHOWAS command reply. Updated
392 the protocol specs accordingly.
394 * Implemented WHOWAS command and command_reply to the client
397 Implemented the WHOWAS printing on the user interface.
399 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
401 * Added new argument to the WHOWAS command reply, the real name.
402 It is an optional argument. Updated the protocol specs.
404 * Added SilcIDCacheDestructor callback that is registered when
405 the SilcIDCache is allocated. The callback is called when
406 an cache entry in the ID Cache expires, or is purged from the
407 cache. Added into lib/silccore/idcache.[ch].
409 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
410 to destruct the client entries when the cache entry expires.
411 Other ID Cache's in server and in the client library ignores
414 * If the ID Cache entry's `expire' field is zero then the entry
415 never expires. Added boolean `expire' argument to the
416 silc_idcache_add function in the lib/silccore/idcache.[ch].
417 If it is TRUE the default expiry value is used.
419 * Added silc_server_free_client_data_timeout that is registered
420 when client disconnects. By default for 5 minutes we preserve
421 the client entry for history - for WHOWAS command.
423 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Added support to the server to enforce that commands are not
426 executed more than once in 2 seconds. If server receives
427 commands from client more frequently, timeout is registered
428 to process the commands. Affected file silcd/command.c.
429 Added new function silc_server_command_process_timeout.
431 * Changed NICK_NOTIFY handling in client library to check that
432 if the client's nickname was changed, so there is no need to
433 resolve anything from the server.
435 * Removed error printing from the WHOIS and IDENTIFY commands.
436 If error occurs then it is ignored silently in the client library.
437 The application, however, may map the received error to
438 human readable error string. The application currently maps
439 the NO_SUCH_NICKNAME error to string.
441 * Made the command status message public to the application. Moved
442 them from lib/silcclient/command_reply.c to
443 lib/silcclient/command_reply.h. The application can map the
444 received command status to the string with the
445 silc_client_command_status_message function.
447 * Added check to the server to check that client's ID is same
448 as the Source ID in the packet the client sent. They must
451 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Added dist-bzip hook to the Makefile.am to make bzip2
454 compressed distributions.
456 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Server now enforces the maximum length for the nickname and
459 the channel as protocol specification dictates. 128 bytes for
460 nickname and 256 bytes for channel name.
462 * Moved the WHOIS printing to the application. The client libary
463 does not print out the WHOIS information anymore, the application
464 must do it. Renamed silc_client_command_reply_whois_print to
465 the silc_client_command_reply_whois_save.
467 The client's idle time is also sent to the application now, and
468 the idle is shown on screen.
470 * Added silc_client_command_reply_identify_save to save the
471 received IDENTIFY entries.
473 * Do not check for channel private keys in message sending and
474 reception if the channel does not have the PRIVKEY mode set.
475 Affected file lib/silclient/client_channel.c.
477 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
480 just surfaced after chaning the JOIN procedure.
482 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Added silc_client_get_clients_by_list to get client entries
485 from Client ID list, that is returned for example by JOIN
486 and USERS command replies. The application should use this
487 function for example when JOIN command reply is received to
488 resolve the clients already on the channel (library does not
489 do that anymore as USERS command reply is not used in the JOIN
490 procedure anymore). Affected files lib/silcclient/silcapi.h and
491 lib/silcclient/idlist.c.
493 * JOIN command reply and USERS command reply returns now SilcBuffer
494 pointers instead of unsigned char pointers when returning
495 the client list and mode list.
497 * Added <Client ID> argument to the JOIN command reply, mainly
498 for the server to identify for which client the command was
499 originally sent. Updated protocol specs accordingly.
501 * Added SilcDlist private_key pointer to the SilcChannelEntry
502 in the client to support the channel private keys. Affected
503 file is lib/silcclient/idlist.h.
505 * Added SilcChannelPrivateKey argument to the function
506 silc_client_send_channel_message so that application can choose
507 to use specific private ke if it wants to. If it is not provided,
508 the normal channel key is used, unless private keys are set.
509 In this case the first (key that was added first) is used
510 as the encryption key.
512 * Implemented the support for channel private key handling.
513 Implemented the following functions:
515 silc_client_add_channel_private_key,
516 silc_client_del_channel_private_keys,
517 silc_client_del_channel_private_key,
518 silc_client_list_channel_private_keys and
519 silc_client_free_channel_private_keys
521 Affected file lib/silcclient/client_channel.c.
523 * Added the support for the private keys in the channel message
524 sending and encryption and in the message reception and
525 decryption. Affected funtions are
526 silc_client_send_channel_message and silc_client_channel_message.
528 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Added SKE's key verify callback to the client library's
531 KE protocol context. Affected files lib/silcclient/protocol.[ch].
533 * Removed the statement that server (or router) must send USERS
534 command reply when joining to the channel so that the client
535 knows who are on the channel. Instead, the client list and
536 client's mode list is now sent in the JOIN command reply to the
537 client who joined channel. This is better solution.
539 * Added function silc_server_get_users_on_channel and function
540 silc_server_save_users_on_channel to the silcd/server.[ch].
542 * Removed function silc_server_command_send_users from the
545 * Do not show topic on the client library anymore. The topic is
546 sent in the command reply notify to the application and the
547 application must show the topic now.
549 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Added client searching by nickname hash into the IDENTIFY and
552 WHOIS commands in the server as they were clearly missing from
553 them. Affected file is silcd/command.c.
555 * Fixed a bug in private message receiving in the client library.
556 The remote ID was freed and it wasn't supposed, now it is
559 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Minor fix to the channel payload; allocate the data area, as it
562 needs to be of specific length.
564 * If the key agreement port is zero then the operating
565 system will define the bound port. Affected files are
566 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
568 * Added new function silc_channel_payload_decrypt into the file
569 lib/silccore/silcchannel.[ch].
571 * Moved the channel message etc, check from silc_packet_decrypt
572 to applications. The library calls now a generic
573 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
574 when the packet is either normal or special. This was done to
575 allow more wide range of checking that was not allowed when
576 the code was in library. Now applications can do virtually any
577 checks to the packet and return to the library the decision how
578 the packet should be processed. Affected files are
579 lib/silccore/silcpacket.[ch].
581 Added silc_server_packet_decrypt_check to the server and
582 silc_client_packet_decrypt_check to the client library.
584 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
585 to send with specified source and destination information.
587 * Channel message delivery between routers was broken after the
588 channel key distribution was fixed earlier. The channel key
589 was used be to distributed to other routers as well which is not
590 allowed by the protocol. Now this is fixed and channel keys
591 really are cell specific and the channel message delivery between
592 routers comply with the protocol specification.
594 * Fixed various commands in server to check also the global list
595 for the channel entry and not just the local list. The affected
596 file silcd/command.c.
598 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Added assert()s to buffer formatting and unformatting routines
601 to assert (if --enable-debug) when error occurs. Affected
602 file: lib/silcutil/silcbuffmt.c.
604 * Changed to auto-reconnect to check whether the remote host is
605 router and register the re-connect timeout if it is. It used
606 to check that whether we are normal server, but router must do
607 auto-reconnect with another router as well. Affected file
610 * Removed the [<key len>] option from CMODE command as the cipher
611 name decides the key length, nowadays. See the defined ciphers
612 from the protocol specification.
614 * Added [<hmac>] option to the CMODE command to define the HMAC
615 for the channel. Added SILC_CMODE_HMAC channel mode.
617 * Added [<hmac>] option for the JOIN command so that user can
618 select which HMAC is used to compute the MACs of the channel
621 * Added Hmac field to the Channel Message Payload. The integrity
622 of plaintext channel messages are now protected by computing
623 MAC of the message and attaching the MAC to the payload. The
624 MAC is encrypted. Now, it is clear that this causes some
625 overhead to the size of the packet but rationale for this is that
626 now the receiver can verify whether the channel message decrypted
627 correctly and also when private keys are set for the channel the
628 receiver can decrypt the packet with several keys and check from
629 the MAC which key decrypted the message correctly.
631 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
632 lib/silccrypt/silccipher.[ch].
634 * Added silc_hash_len to return the digest length into the
635 lib/silcrypt/silchash.[ch].
637 * Rewrote parts of Silc Channel Payload interface in the
638 lib/silccore/silcchannel.[ch]. The encode function now also
639 encrypts the packet and parse function decrypts it.
641 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Fixed a minor formatting bug in the SKE's key material processing.
644 It actually might have processed the keys wrong way resulting
647 * Redefined the mandatory HMAC algorithms and added new algorithms.
648 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
649 and hmac-md5 truncated to 96 bits. The mandatory is now
650 hmac-sha1-96. Rest are optional (including the one that used
651 to be mandatory). Rationale for this is that the truncated HMAC
652 length is sufficient from security point of view and can actually
653 make the attack against the HMAC harder. Also, the truncated
654 HMAC causes less overhead to the packets. See the RFC2104 for
657 * Added new [hmac] configuration section. The SKE used to use
658 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
659 is of course wrong. The official names that must be proposed in
660 the SKE are the ones defined in the protocol specification
661 (hmac-sha1-96 for example). The user can configure any hmac
662 using any hash function configured in the [hash] section. At
663 least, the mandatory must be configured.
665 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
667 * Added HMAC list to the SKE proposal list. It has now both
668 hash algorithm list and HMAC list. This makes the protocol
669 incompatible with previous versions. The SKE now seems to work
670 the way it is supposed to work, for the first time actually.
672 * Defined plain Hash algorithms to the protocol specification.
675 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Implemented support for key agreement packets into the server.
678 Added functions silc_server_key_agreement and
679 silc_server_send_key_agreement. Other than these functions,
680 server has nothing to do with this packet.
682 * Added support for private message key packets into the server.
683 Added functions silc_server_private_message_key and
684 silc_server_send_private_message_key.
688 * Changed the silc_[client|server]_protocol_ke_set_keys to be
689 called in the protocol's final callback instead in the END
690 protocol state. This makes a little more sense and in the same
691 time in client we can use the same protocol routines for normal
692 key exchange and to key agreement packet handling as well.
694 * Added to both client's and server's KE protocol context the
695 SilcSKEKeyMaterial pointer to save the key material. We will
696 bring the key material to the protocol's final callback by doing
697 this. The final callback must free the key material.
699 * Added SKE's packet_send callback into client's KE protocol
700 context so that the caller can choose what packet sending function
701 is used. This way we can use different packet sending when
702 doing normal SKE when doing key agreement packet handling (in
703 the key agreement packet handling we do not want to encrypt
706 * Implemented the responder side of the key agreement routines
707 in the client. The client can now bind to specified port and
708 accept incoming key negotiation. The key material is passed
709 to the application after the protocol is over.
711 * Implemented the processing of incoming Key Agreement packet
712 in the client. Added function silc_client_key_agreement to
715 * Implemented the intiator side of the key agreement routines
716 in the client. The client can now initiate key agreement with
717 another remote client. The key material is passed to the
718 application after the protocol is over.
720 * Created client_keyagr.c to include all the key agreement
723 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
724 SILC_TASK_CALLBACK except that it is not static.
726 * Created client_notify.c and moved the Notify packet handling
727 from the client.[ch] into that file.
729 * Created client_prvmsg.c and moved all private message and
730 private message key routines from the client.[ch] into that file.
732 * Create client_channel.c and moved all channel message and
733 channel private key routines from the client.[ch] into that file.
735 * Changed silc_client_get_client_by_id_resolve to resolve with
736 WHOIS command instead of IDENTIFY command, in the file
737 lib/silclient/idlist.c.
739 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Implemented the SKE's responder side to the Client library.
743 * When FAILURE is received to the protocol do not trust it
744 blindly. Register a timeout to wait whether the remote closes
745 the connection as it should do it, only after that process the
746 actual failure. This was changed to both client and server.
748 * Added client_internal.h to include some of the structures
749 there instead of client.h in lib/silcclient/.
751 * Added function silc_task_unregister_by_callback to unregister
752 timeouts by the callback function.
754 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Some "Incomplete WHOIS info" errors has been appearing on the
757 log files. Took away the entry->userinfo check from WHOIS
758 reply sending. The entry->userinfo is now " " if client did not
759 provide one. I thought this was fixed earlier but something
760 is wrong still. Let's see if the error still appears.
762 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Fixed a minor bug in the login when the channel key is
765 re-generated in the server. It used to generate the key in
766 wrong order and thus caused problems in the channel traffic.
768 * Fixed a minor bug in channel key distsribution after
769 KICK command. The key was not sent to the router even though
772 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Added silc_ske_process_key_material_data as generic routine
775 to process any key material as the SILC protocol dictates. The
776 function is used by the actual SKE library but can be used by
777 applications as well. This relates to the private message keys
778 and the channel private keys since they must be processed the
779 same way the normal SILC session keys. The protocol dictates
780 this. Affected files: lib/silcske/silcske.[ch].
782 Added also silc_ske_free_key_material to free the
783 SilcSKEKeyMaterial structure.
785 * Defined silc_cipher_set_key function to set the key for
786 cipher without using the object's method function. The affected
787 files: lib/silccrypt/silccipher.[ch].
789 * Implemented silc silc_client_add_private_message_key,
790 silc_client_add_private_message_key_ske,
791 silc_client_del_private_message_key,
792 silc_client_list_private_message_keys and
793 silc_client_free_private_message_keys functions in the
796 Added functions silc_client_send_private_message_key to send
797 the Private Message Key payload and silc_client_private_message_key
798 to handle incoming Private Message Key payload.
800 * Added Cipher field to the Private Message Key payload to set
801 the cipher to be used. If ignored, the default cipher defined
802 in the SILC protocol (aes-256-cbc) is used.
804 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Removed lib/silcclient/ops.h file.
808 Redefined parts of the SILC Client Library API. Created new
809 file silcapi.h that deprecates the ops.h file and defines the
810 published Client Library API. Defined also private message key
811 API and channel private key API into the file.
813 This is the file that the application must include from the
814 SILC Client Library. Other files need not be included by
815 the application anymore.
817 * Added new key_agreement client operation callback and also
818 defined the Key Agreement library API for the application.
820 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
823 is used by clients to request key negotiation between another
824 client in the SILC network. If the negotiation is started it
825 is performed using the SKE protocol. The result of the
826 negotiation, the secret key material, can be used for example
827 as private message key.
829 Implemented the Key Agreement payload into the files
830 lib/silccore/silauth.[ch].
832 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Redefined ciphers for the SILC protocol. Added some new ciphers
835 and defined the key lengths for the algorithms. Changed the
836 code accordingly. The default key length is now 256 bits.
838 * Fixed SKE key distribution function silc_ske_process_key_material
839 when the key length is more than 128 bits. The default key
840 length in SILC is now 256 bits.
842 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
843 to indicate unsupported algorithm.
845 * Renamed rijndael.c to aes.c and all functions as well.
847 * Fixed a long standing channel key setting bug in client library.
848 Weird that it has never surfaced before.
850 * Fixed bug in channel deletion. If the entire channel is removed
851 then it must also delete the references of the channel entry
852 from the client's channel list as the client's channel entry and
853 the channel's client entry share same memory.
855 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Implemented CONNECT and SHUTDOWN commands in the client.
859 * Implemented CLOSE command to the client.
861 * Added the function silc_idlist_find_server_by_name into the
862 files silcd/idlist.[ch].
864 Added the function silc_idlist_find_server_by_conn into the
865 files silcd/idlist.[ch].
867 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * DIE command was renamed to SHUTDOWN. Updated the both code
872 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
873 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
875 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
878 * Added function silc_server_create_connection function to create
879 connection to remote router. My server implementation actually
880 does not allow router to connect to normal server (it expects
881 that normal server always initiates the connection to the router)
882 so the CONNECT command is only good for connecting to another
885 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
888 or some other client was kicked from the channel.
890 Implemented the handling of the notify type to both client
893 Implemented silc_server_send_notify_kicked to send the KICKED
894 notify. It is used to send it to the server's primary router.
896 * Implemented the KICK command into server and client.
898 * Added `query' argument to the silc_idlist_get_client function
899 to indicate whether to query the client from server or not if
902 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
903 to indicate that the client is not channel founder.
907 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Removed the rng context from SilcPacketContext structure and
910 changed that the packet routine uses the Global RNG API.
912 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added support for quit message that client can "leave" on the
915 channel when it quits the SILC. It is ditributed inside the
916 SILC_NOTIFY_TYPE_SIGNOFF notify type.
918 Added silc_server_free_client_data that will take the
919 signoff message as argument.
921 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
923 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Updated parts of the protocol specification to keep it up
928 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
931 payloads in one packet.
933 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
934 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
935 use now the new List flag.
937 * Also deprecated the following packet types: REPLACE_ID,
938 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
940 * Added list support for Notify packet in server.
942 * Added silc_server_send_notify_channel_change to send the
943 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
944 the silc_server_send_replace_id.
946 * Added silc_server_send_notify_nick_change to send the
947 NICK_CHANGE notify type. Deprecates the function
948 silc_server_send_replace_id.
950 * Added silc_server_send_notify_join to send the JOIN notify type.
951 Deprecates the function silc_server_send_new_channel_user.
953 * Added silc_server_send_notify_leave to send LEAVE notify type.
954 Deprecates the function silc_server_send_remove_channel_user.
956 * Added silc_server_send_notify_cmode and
957 silc_server_send_notify_cumode to send CMODE and CUMODE notify
958 types. Deprecates the silc_server_send_set_mode function.
960 * Added SERVER_SIGNOFF notify type to indicate that server has
961 quit. This means that all clients on the channel from that
962 server will drop. This can be also used when netsplit happens.
964 Deprecated REMOVE_ID packet type since it is not needed anymore
967 Added silc_server_send_notify_server_signoff to send the
968 SERVER_SIGNOFF notify type. Deprecates the function
969 silc_server_send_remove_id.
971 Added also silc_server_send_notify_signoff to send the
974 * Employed the PKCS #1. It is the mandatory way to do RSA in the
975 SILC protocol from this day on. Changed the protocol
976 specification as well.
978 * Added silc_server_send_notify_topic_set to send TOPIC_SET
979 notify type. It is used between routers to notify about
980 topic changes on a channel.
982 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
985 * Partly updated the protocol specification to comply with the
986 changes now made. It is still though a bit outdated.
988 * The JOIN notify type now takes one extra argument <Channel ID>.
989 The packet used to be destined to the channel but now the
990 JOIN type may be sent as list thus it is impossible to
991 destine it to any specific channel. By adding this argument
992 it is again possible.
994 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Added CREDITS file. The CHANGES and CREDITS file will appear
997 in the distribution as well.
999 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1002 types in the server's silcd/packet_receive.c.
1004 * Implemented CMODE and CUMODE to work in router environment.
1006 * Fixed minor encoding and decoding buglet from the
1007 lib/silccore/silcmode.c.
1009 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1012 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1014 * Changed all SilcConfigServer* and silc_config_server* to
1015 SilcServerConfig* and silc_server_config*, respectively.
1018 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Associated the ID (client or server ID) to the Authentication
1021 Payload to avoid any possibility of forging. Updated the
1022 protocol specification and the code accordingly.
1024 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * The RSA key length is now save to the RsaKey context in the
1027 key generation process in lib/silccrypt/rsa.c. The key length
1028 is now used to figure out the maximum size of the block allowed
1029 to be encrypted/signed.
1031 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1032 is equivalent to the silc_mp_mp2bin but does not allocate any
1035 * Changed silc_mp_mp2bin API to take length argument. If it is
1036 non-zero then the buffer is allocated that large. If zero, then
1037 the size is approximated using silc_mp_sizeinbase, which however
1040 * Created Global RNG API which is global RNG that application can
1041 initialize. After initializing, any routine anywhere in the
1042 code (including library) can use RNG without allocating a new
1043 RNG object. This was done to allow this sort of use of the
1044 RNG in code that has no chance to allocate RNG object. All
1045 applications currently allocate this and many routines in the
1046 library use this. Affected file lib/silccrypt/silcrng.[ch].
1048 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1049 it to use the Global RNG API.
1051 * Defined Authentication Payload into protocol specification that
1052 is used during SILC session to authenticate entities. It is
1053 used for example by client to authenticate itself to the server
1054 to obtain server operator privileges.
1056 Implemented this payload into the lib/silccore/silcauth.[ch].
1057 Implemented also routines for public key based authentication
1058 as the new protocol specification dictates.
1060 Moved definitions of different authentication methods from
1061 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1063 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1064 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1065 silc_pkcs_verify_with_hash functions into the file
1066 lib/silccrypt/silcpkcs.[ch].
1068 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * The client entry's userinfo pointer must be always valid.
1071 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1072 will fail since it requires the userinfo. Now, the userinfo
1073 is allocated as "" if actual userinfo does not exist. Actually,
1074 it must exist and it is totally Ok to drop client connections
1075 that does not announce the userinfo. However, we will make
1076 this workaround for now.
1078 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1079 to return the remote port by socket.
1081 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1083 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1084 SILC_SERVER_PENDING_EXEC and added an new macro
1085 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1086 data or when error occurs while processing the pending command.
1088 Added new argument `destructor' into silc_server_command_pending
1089 and to the SilcServerCommandPending object. This destructor is
1090 now called after calling the pending callback or if error occurs
1091 immediately. If error occurs the actual pending callback won't
1092 be called at all - only the destructor. The destructor may be
1093 NULL if destructor is not needed.
1095 All this applies for client library code as well. Similar
1096 changes were made there as well for the pending commands.
1098 In the client, the application must now allocate the
1099 SilcClientCommandContext with the silc_client_command_alloc
1102 * Added reference counter to the SilcServerCommandContext. Added
1103 function silc_server_command_alloc and silc_server_command_dup
1106 Same type of functions added to the client library for the same
1109 * Removed the cmd_ident from IDListData away since it is now
1110 global for all connections. It is the command identifier used
1111 in command sending and with pending commands. The affected file
1114 * Added reference counter to the SilcSocketConnection objecet to
1115 indicate the usage count of the object. The object won't be
1116 freed untill the reference counter hits zero. Currently only
1117 server uses this, and client ignores it. The client must be
1118 set to use this too later. The affected files are
1119 lib/silccore/silcsockconn.[ch]. Added also the function
1120 silc_socket_dup to increase the reference counter.
1122 This was mainly added because it is possible that the socket
1123 is removed underneath of pending command or other async
1124 operation. Now it won't be free'd and proper DISCONNECTING
1125 flags, etc. can be set to avoid sending data to connection that
1126 is not valid anymore.
1128 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1129 the connection. After that it sets SILC_SET_DISCONNECTED.
1130 It is, however, possible that the socket data is not still freed.
1131 The silc_server_packet_process now checks that data is not
1132 read or written to connection that is DISCONNECTED. The socket
1133 get's freed when the reference counter hits zero.
1135 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Changed the client operation API: channel_message operation's
1138 `sender' is now the client entry of the sender, not the nickname
1139 and the `channel' is the channel entry, not the channel name.
1141 In the private_message operation the `sender' is now also the
1142 client entry of the sender not the nickname.
1144 Affected file is lib/silcclient/ops.h and all applications
1145 using the client operations.
1147 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Moved the calling of ops->connect() from connect_to_server_final
1150 into receive_new_id functin since that is the point when the
1151 client is actually allowed to send traffic to network. The
1152 affected file is lib/silcclient/client.c.
1154 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1157 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1158 (if needs broadcasting) instead of broadcasting the packets one
1159 by one which would make a burst in the network traffic.
1161 * Added `broadcast' argument to the functions in silcd/server.[ch]
1162 silc_server_create_new_channel[_with_id] to indicate whether
1163 to send New Channel packet to primary router.
1165 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Added new function into the silcd/server.[ch] files:
1168 silc_server_create_new_channel_with_id to create new channel with
1169 already existing Channel ID.
1171 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1172 lib/silccore/silcpacket.h. This packet is used t send list of
1173 Set Mode payloads inside one packet. Server uses this to set
1174 the modes for the channels and clients on those channels, that it
1175 announced to the router when it connected to it. The protocol
1176 specification has been updated accordingly.
1178 * The silc_server_new_channel did not handle the packet coming
1179 from normal server as it normally does not send that. However,
1180 when it announces its channels it does send it. Implemented
1181 the support for that.
1183 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1184 into the file lib/silccore/id.h.
1186 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Fixed memory leaks in the functions silc_idlist_del_client,
1189 silc_idlist_del_channel and silc_idlist_del_server in the file
1190 silcd/idlist.c. All of those leaked like a sieve.
1192 * Fixed some small memory leaks in the client's function
1193 silc_client_notify_by_server.
1195 * Added functions into silcd/server.c: silc_server_announce_clients,
1196 silc_server_announce_channels and silc_server_announce_server.
1197 These functions are used by normal and router server to announce
1198 to its primary router about clients, channels and servers (when
1199 router) that we own. This is done after we've connected to the
1202 These functions effectively implements the following packet types:
1203 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1204 and SILC_PACKET_NEW_ID_LIST.
1206 * Added new functions into the silcd/packet_receive.[ch]:
1207 silc_server_new_id_list, silc_server_new_channel_list and
1208 silc_server_new_channel_user_list to handle the incoming
1209 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1211 * Added support of changing Channel ID in the function
1212 silc_server_replace_id. If the server that announces a channel
1213 to the router already exists in the router (with same name but
1214 with different Channel ID), router is responsible to send
1215 Replace ID packet to the server and force the server to change
1216 the Channel ID to the one router has.
1218 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1219 client that the Channel ID has been changed by the router. The
1220 normal server sends this to the client. Client must start using
1221 the new Channel ID as the channel's ID.
1223 Implemented handling of this new type into lib/silcclient/client.c
1224 into the function silc_client_notify_by_server.
1226 * Added new function silc_idlist_replace_channel_id into the files
1227 silcd/idlist.[ch] to replace the Channel ID.
1229 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Call silc_server_command_identify_check always when processing
1232 the IDENTIFY command in silcd/command.c
1234 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1237 send keepalive packets. The packet can be sent by clients,
1238 servers and routers.
1240 Added function silc_socket_set_heartbeat into the file
1241 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1242 If not set, the heartbeat is not performed. The actual
1243 heartbeat is implemented in the low level socket connection
1244 library. However, application is responsible of actually
1247 Added silc_server_send_heartbeat to send the actual heartbeat
1248 packet into silcd/packet_send.[ch]. Server now performs
1249 keepalive with all connections.
1251 * Added silc_task_get_first function into lib/silcutil/silctask.c
1252 to return the timeout task with shortest timeout. There was a bug
1253 in task unregistration that caused problems. TODO has been
1254 updated to include that task system must be rewritten.
1256 * The client library will now resolve the client information when
1257 receiving JOIN notify from server for client that we know but
1258 have incomplete information.
1260 * Rewrote parts of silc_server_remove_from_channels and
1261 silc_server_remove_from_one_channel as they did not remove the
1262 channel in some circumstances even though they should've.
1264 * Encryption problem encountered in server:
1266 The LEAVE command used to send the Channel Key packet to the
1267 router immediately after generating it. However, the code
1268 had earlier sent Remove Channel user packet but not immediately,
1269 ie. it was put to queue. The order of packets in the router
1270 was that Channel Key packet was first and Remove Channel User
1271 packet was second, even though they were encrypted in the
1272 reverse order. For this reason, MAC check failed. Now, this
1273 is fixed by not sending the Channel Key packet immediately but
1274 putting it to queue. However, this is more fundamental problem:
1275 packets that are in queue should actually not be encrypted
1276 because packets that are sent immediately gets encrypted
1277 actually with wrong IV (and thus MAC check fails). So, packets
1278 that are in queue should be encrypted when they are sent to
1279 the wire and not when they put to the queue.
1281 However, the problem is that the current system has not been
1282 designed to work that way. Instead, the packet is encrypted
1283 as soon as possible and left to the queue. The queue is then
1284 just purged into wire. There won't be any fixes for this
1285 any time soon. So, the current semantic for packet sending
1288 o If you send packet to remote host and do not force the send
1289 (the packet will be in queue) then all subsequent packets to the
1290 same remote host must also be put to the queue. Only after the
1291 queue has been purged is it safe again to force the packet
1294 o If you send all packets immediately then it safe to send
1295 any of subsequent packets through the queue, however, after
1296 the first packet is put to queue then any subsequent packets
1297 must also be put to the queue.
1299 Follow these rules and everything works fine.
1301 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1303 * Added new function silc_server_remove_clients_by_server to
1304 remove all client entries from ID list when the server connection
1305 is lost. In this case it is also important to invalidate all
1306 client entires as they hold the invalid server entry. This
1307 fixes fatal bug when server has lost connection and will reconnect
1310 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Made some sanity checks to silc_server_daemonise like to check
1313 whether the requested user and group actually exists.
1315 * Added sanity check to SKE's silc_ske_responder_finish to check
1316 that the public and private key actually is valid.
1318 * Invalidate the client's nickname when receiving Replace ID
1319 packet and the Client ID is being replaced. This means that the
1320 server will query the nickname if someone needs it (client)
1323 * Sort the ID Cache in client library when the ID Cache data
1324 has changed (needs sorting).
1326 * Do not allow for SILC client to create several connections to
1327 several servers. The client does not support windows right now
1328 and generating multiple connections causes weird behaviour.
1330 Irssi-silc client does support windows and can handle several
1331 connections without problems, see: www.irssi.org and SILC plugin.
1333 * Fixed some places where client was added to the IDList. The
1334 rule of thumb is following (in order to get everything right):
1335 If the client is directly connected local client then the
1336 `connection' argument must be set and `router' argument must be
1337 NULL to silc_idlist_add_client function. If the client is not
1338 directly connected client then the `router' argument must
1339 bet set and the `connection' argument must be NULL to the
1340 silc_idlist_add_client function.
1342 * The funtion silc_server_packet_send_local_channel actually did
1343 not check whether the client was locally connected or not. It
1344 does that now. Fixed a bug related to LEAVE command.
1346 * Fixed Remove Channel User payload parsing bug in server's
1347 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1349 * The server's silc_server_save_channel_key now checks also the
1350 global ID list for the channel as it might not be in the local
1351 list. Fixed a bug related to LEAVE command.
1353 * Is this the end of the [<unknown>] buglet that has been lurking
1354 around for a long time? A little for loop fix in server's
1355 silc_server_command_whois_parse that is used by both IDENTIFY
1356 and WHOIS command. At least, this was a clear bug and a cause
1357 of one type of [<unknown>] buglet.
1359 * WHOIS and IDENTIFY commands call the function
1360 silc_server_command_[whois/identify]_check function even if
1361 we are not router server.
1363 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Added --with-gmp configuration option. If set the GMP
1366 is always compiled in the SILC source tree. If not set then
1367 it is checked whether the system has the GMP3 installed. If
1368 it has then the GMP won't be compiled (the system's headers
1369 and library is used), if it doesn't have it then the GMP is
1370 compiled in the SILC source tree.
1372 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Changed RSA private exponent generation to what PKCS #1
1375 suggests. We try to find the smallest possible d by doing
1376 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1377 not security fix but optimization.
1379 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Added new config entry [Identity] to fork the server and run
1382 it as specific user and group. A patch from Bostik.
1384 * Imported Dotconf configuration library into lib/dotconf.
1385 This will be used to create the SILC configuration files later.
1386 It will appear in the distsribution after this commit.
1388 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * A big code auditing weekend happening. Auditing code for
1391 obvious mistakes, bugs and errors. Also, removing any code
1394 Removed files for being obsolete:
1396 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1397 inline in the file lib/silcutil/silcbuffer.h)
1399 o lib/silcutil/silcbufutil.c (the header has inline versions)
1401 Changed code to fix possible error conditions:
1403 o The buffer formatting routines now check that the destination
1404 buffer really has enough space to add the data. This applies for
1405 both buffer formatting and unformatting
1406 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1407 unformatting was changed to accomodate following rules:
1408 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1409 sent to the function while XXX_*STRING will not allocate or copy
1410 the data into the buffer. Instead it sets the pointer from the
1411 buffer into the pointer sent as argument (XXX_*STRING used to
1412 require that the pointer must be allocated already). This change
1413 makes this whole thing a bit more consistent and more optimized
1414 (note that the data returned in the unformatting with XXX_*STRING
1415 must not be freed now). The routines return now -1 on error.
1417 o Tried to find all code that use buffer_format and buffer_unformat
1418 and added return value checking to prevent formatting and
1419 especially unformatting errors and possible subsequent fatal
1422 o Changed ske->x and ske->KEY to mallocated pointers in
1423 lib/silcske/silcske.h. Fixed possible data and memory leak.
1425 o Added return value checking to all *_parse* functions. Fixed
1426 many memory leaks as well.
1428 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1429 so that buffer overflows would not happen. All code now also
1430 checks the return value as it can fail.
1432 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Added reconnection support to server if the normal server looses
1435 its connection to the router (for example if router is rebooted).
1436 The server performs normal reconnection strategy implemented
1437 to the server. Affected file silcd/server.c.
1439 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1441 * Added new packet type SILC_PACKET_SET_MODE that is used to
1442 distribute the information about changed modes (for clients,
1443 channels and clients channel modes) to all routers in the
1444 network. Updated the protocol specification accordingly.
1446 Added functions into silcd/packet_send.c and
1447 silcd/packet_receive.c: silc_server_send_set_mode,
1448 silc_server_set_mode.
1450 Added new files silcmode.[ch] into lib/silccore that implements
1451 the encoding and decoding of Set Mode Payload. Added new type
1452 SilcSetModePayload. Moved the definitions of different modes
1453 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1455 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1457 * Oops, a little mistake in server's connection authentication
1458 protocol. The protocol is not ended with FAILURE but with
1459 SUCCESS if the authentication is Ok. :) Affected file is
1462 * Implemented NICK_CHANGE notify handling in server in the file
1463 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1464 the local clients on the channel. After the changing nickname
1465 in router environment snhould work and the [<unknown>] nickname
1466 should appear no more.
1468 The silc_server_replace_id function that receives the Replace ID
1469 payload now sends the NICK_CHANGE notify type also in the file
1470 silcd/packet_receive.c
1472 * Changed WHOIS and IDENTIFY command to support the maximum amount
1473 of arguments defined in protocol specs (3328 arguments). This
1474 fixed a bug that caused problems when there were more than three
1477 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1479 * Added extra parameter, command identifier, to the
1480 silc_client_send_command so that explicit command identifier
1483 Changed that ID list routines uses specific command identifier
1484 when sending WHOIS/IDENTIFY requests to the server so that they
1485 can be identified when the reply comes back.
1487 Affected files lib/silcclient/command.[ch],
1488 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1490 * Added `sender' argument to silc_server_packet_send_to_channel
1491 to indicaet the sender who originally sent the packet to us
1492 that we are now re-sending. Ignored if NULL. Affected file
1493 silcd/packet_send.[ch].
1495 * Added some server statistics support in silcd/server_internal.h
1496 SilcServerStatistics structure and around the server code. Also
1497 send some nice statistics information when client is connecting
1500 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Fixed channel ID decoding in server's JOIN command reply in
1503 silcd/command_reply.c
1505 * Fixed braodcasting of replace ID payload to not to send it if
1506 we are standalone server in silcd/packet_receive.c.
1508 * Fixed all channel message sending routines to not to send
1509 packets to clients that has router set, since they are routed
1510 separately in the same function earlier. Affects file
1511 silcd/packet_send.c and all channel packet sending functions.
1513 * In USERS reply, res_argv[i] are not allocated, the table
1514 is allocated. Thus changed that free the table, not its
1517 * In server's whois_check and identify_check if the client is
1518 locally connected do not send any WHOIS commands - they are not
1521 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Fixed some minor bugs in client when sending WHOIS command. The
1524 arguments was in wrong order.
1526 * Removed statis function add_to_channel from server in
1527 silcd/command.c that was previously used with the joining but
1530 * Tested USERS command in router environment successfully with two
1531 routers, two servers and two clients.
1533 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Reorganized the USERS command and command reply in client library
1536 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1537 When the command is given by user we register a pending command
1538 callback that will reprocess the command after the reply has been
1539 received from the server. When reprocessing the packet we then
1540 display the information. Thus, the USERS information is displayed
1541 now in the command callback instead of in the command reply
1542 callback. The processing of the command is same as previously
1543 when server has sent the command reply in the JOINing process.
1545 * Added to USERS command in silcd/command_reply.c to join the client,
1546 we didn't use to know about, to the channel after we've created
1547 a client entry for it. Also, for clienet we did know already still
1548 check whether it is on the channel or not and add it if not.
1550 * Removed silc_server_command_join_notify as the function and its
1553 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Changed the client's pending command handling to the same as the
1556 server's pending command handling. It is also now possible to
1557 execute command reply functions from other command reply
1558 function as the function callbacks for commands and command
1559 replies are one and same. The pending commands are not static
1560 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1561 in client connection context. Thus, pending commands are server
1562 connection specific as it is convenient.
1564 Changed the function silc_client_command_pending and
1565 silc_client_command_pending_del and added new function
1566 silc_client_command_pending_check. Removed the
1567 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1570 * Added cmd_ident, current command identifier, to the client
1571 connection context in lib/silcclient/client.h to keep track on
1572 command identifiers used in command sending. Client's command reply
1573 function handling now supports the mandatory command identifiers.
1575 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1576 funtions in client to fully support pending command callbacks.
1578 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1579 as one of the arguments to the application in the command reply
1582 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1583 before first releasing SILC but came back. Now it is removed again
1584 and should come back nomore. The FORWARDED flag was used only
1585 by the JOINing procedure by forwarding the command packet to router.
1586 Now, the JOINing procedure has been changed to more generic (due
1587 to various router environment issues) and FORWARDED is not needed
1588 anymore for anything. The protocol specification is yet to be
1591 Now, removed silc_server_packet_forward from server and the flag
1592 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1594 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * Renamed NAMES command to USERS command. The NAMES was named that
1597 due to historical reasons. Now it is renamed. Also, rewrote
1598 parts of the USERS command. The nickname list is not sent anymore
1599 by the server. Only Client ID and mode lists are sent in the USERS
1600 command. Changed this also to the protocol specification.
1602 The client now resolves the names and stuff after it receives
1603 the USERS list from the server when joining to the channel.
1605 * WHOIS and IDENTIFY commands has been changed to support multiple
1606 Client ID's per command. One can now search for multiple users
1607 in the network by sending only one WHOIS or IDENTIFY command.
1608 Changed the code and the protocol specifications.
1610 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1611 uses silc_server_command_whois_parse to parse the request. */
1613 * If normal server, do not parse the WHOIS and IDENTIFY requests
1614 before sending it to the router. Saves some time.
1616 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Fixed JOIN command on client library. Wrong number of arguments
1619 used to crash the client.
1621 * Added silc_server_channel_has_global function to check whether
1622 channel has global users or not.
1624 * Added silc_server_channel_has_local function to check whether channel
1625 has locally connected clients on the channel.
1627 * The silc_server_remove_from_one_channel now checks whether the
1628 channel has global users or not after given client was removed from
1629 the channel. It also checks whether the channel has local clients
1630 on the channel anymore. If it does not have then the channel entry
1631 is removed as it is not needed anymore.
1633 * The silc_server_notify now checks on JOIN notify whether the joining
1634 client is one of locally connected or global. If it is global then
1635 the channel has now global users on the channel and that is marked
1636 to the channel entry. Also, it now saves the global client to
1637 global list who is joining and JOINs it to the channel. This is
1638 for normal server, that is.
1640 Changed silc_server_send_notify_on_channel,
1641 silc_server_packet_relay_to_channel and
1642 silc_server_packet_send_to_channel check if we are normal server
1643 and client has router set (ie. global client) do not send the
1644 message to that client, as it is already routed to our router.
1646 * Implemented LEAVE notify type handling in silc_server_notify
1649 * Tested LEAVE command in router environment successfully. Tested
1650 with two routers, two servers and two clients.
1654 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1656 * Implemented SIGNOFF notify type handling in silc_server_notify
1659 * silc_server_remove_id now removes the client entry from all channels
1660 it has joined and thusly sends SIGNOFF notify type.
1662 * Rewrote the NAMES list generation in server by removing two excess
1663 loops. The lists are created now inside one loop.
1665 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * silc_server_remove_channel_user checks now also global list
1668 for channel and client.
1670 * silc_server_new_channel_user checks now both local and global
1671 list for channel and client. Fixed a bug in client id decoding.
1672 Used to decode wrong buffer.
1674 * silc_server_channel_message checks now both local and global
1675 list for channel entry.
1677 * Tested channel joining (hence JOIN) in router environment
1678 successfully. Tested with two routers, two servers and two
1681 * Tested channel message sending in router environment successfully.
1683 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * Added silc_server_save_channel_key into server.[ch] to save the
1686 received channel key in Channel Key payload processing. It is
1687 also used in JOIN command reply handling.
1689 Equivalent function silc_client_save_channel_key added into
1690 client.[ch] into client library.
1692 * Changed JOIN command reply to send information whether the channel
1693 was created or not (is existing already) and the channel key
1694 payload. Changed protocol specs accordingly.
1696 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1697 the request was sent by ID and not by nickname. Crashed on
1700 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1703 now correctly save the received data.
1705 * silc_server_free_sock_user_data now notifies routers in the
1706 network about entities leaving the network.
1708 At the same time implemented functions silc_server_remove_id
1709 and silc_server_send_remove_id to receive and send REMOVE_ID
1710 packets. The packet is used to notify routers in the network
1711 about leaving entities. The ID removed will become invalid in
1714 * Added function silc_idlist_del_server into server. Removes and
1715 free's server entry from ID list.
1717 * silc_server_private_message function now checks, if we are router,
1718 that the destination ID really is valid ID, naturally.
1720 * In router when NEW_ID packet is received (for new client) the
1721 hash of the Client ID is saved in the ID Cache but the
1722 client->nickname is set to NULL, instead of putting the hash
1725 IDENTIFY command now also checks that client->nickname must be
1726 valid. If it is not if will request the data from the server who
1727 owns the client. Added new function
1728 silc_server_command_identify_check.
1730 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1731 to set the command to already allocated Command Payload.
1733 * Tested private message sending in router environment with two
1734 routers, two servers and two clients. Fixed minor bugs and now
1737 * Fixed segfault from client's NAMES command. Used to crash if
1740 * Forwarded packets must not be routed even if it is not destined
1741 to the receiver. Changed server code comply with this.
1743 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Added `require_reverse_mapping' boolean value to ServerParams
1746 structure. If TRUE (not default) the server will require that
1747 the connecting host has fully qualified domain name.
1749 If the reverse mapping is not required and hostname could not be
1750 found the IP address is used as hostname.
1752 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Implemented version string checking to both client and server.
1755 The check is incomplete currently due to the abnormal version
1756 strings used in development version of SILC.
1758 * Changed all command functions in server to use the new
1761 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1763 * Changed char *data to unsigned char *data in ID Cache system to
1764 support binary data as ID Cache data. Changed code to support
1765 binary data in lib/silccore/idcache.c.
1767 * Renamed silc_server_packet_relay_command_reply to
1768 silc_server_command_reply as it is normal packet receiving
1769 function. Rewrote the function to accept command replys for
1770 servers and not only for clients.
1772 * Mark remote router always as registered server if we are connecting
1773 to it. Otherwise, commands sent by the router to us are ignored.
1775 * All ID List find routines now returns the ID Cache Entry pointer
1776 as well if requested.
1778 * WHOIS command works now in router environment, tested with two
1779 routers, two servers and two clients.
1781 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1782 in router environment (as it is almost equivalent to WHOIS) but
1783 hasn't been tested thoroughly. Added new functions:
1785 silc_server_command_identify_parse
1786 silc_server_command_identify_send_reply
1787 silc_server_command_identify_from_client
1788 silc_server_command_identify_from_server
1790 * Disabled route cache adding because adding two different ID's with
1791 same IP replaces the old cache entry thus giving wrong route.
1792 The entry->router->connection is always the fastest route anyway
1793 so route cache may not be needed. Of course, new routes maybe
1794 established after receiving the ID when the entry->router->connection
1795 might not be anymore the most optimal.
1797 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Add route cache for received ID for fast routing.
1801 * Added silc_server_packet_route to route received packet on router
1802 that is not destined to us.
1804 * Renamed silc_server_get_route to silc_server_route_get.
1806 * Added id_string and id_string_len fields into SilcServer to
1807 include encoded ServerID for fast comparing without excess
1808 encoding of the ID's.
1810 * Cleaned up WHOIS command on server side. Added following static
1813 silc_server_command_whois_parse
1814 silc_server_command_whois_check
1815 silc_server_command_whois_send_reply
1816 silc_server_command_whois_from_client
1817 silc_server_command_whois_from_server
1819 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1820 arguments in command replies. All command functions should be
1821 updated to use this macro.
1823 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Minor typo fixes on command reply handling on server.
1827 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added silc_server_command_add_to_channel internal routine to add
1830 the client to the channel after router has created the channel and
1831 sent command reply to the server.
1833 * Added generic silc_server_send_command to send any command from
1836 * Use static buffer with ID rendering instead of duplicating data.
1838 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Fixed a channel user mode bug when joining to a channel server gave
1841 everybody channel founder rights, oops.
1843 * We mark ourselves as the router of the incoming server connection
1844 if we are router ourselves. This way we can check in some packet
1845 sending functions whether it is locally connected server. For
1846 incoming router connections we put NULL.
1848 * For router sending packets locally means now always sending the
1849 packet cell wide; to local clients and local servers. For normal
1850 server sending packet locally means sending it to only local
1853 * Fixed the JOIN command to really work in router environment. If the
1854 channel is created it is always created by the router. Router is
1855 also responsible of making the initial joining to the channel,
1856 sending JOIN notify to the sending server and distributing
1857 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1858 does not exist server doesn't do anything else but forward the
1859 command to the router which performs everything.
1861 * Added silc_server_send_channel_key function to send the Channel Key
1864 * Added silc_server_create_channel_key to create new channel key. The
1865 channel key is now re-generated everytime someone joins or leaves
1866 a channel, as protocol dictates. Note: channel->key_len is the
1869 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1872 packet_receive.[ch] to separate packet sending and receiving
1873 routines. The server.[ch] now includes everything else including
1874 actual packet processing (writing and reading data) and other
1877 Renamed silc_server_private_message_send_internal to
1878 silc_server_send_private_message. The routine is still though
1879 used only to relay private messages as server does not send
1880 private messages itself.
1882 Renamed silc_server_new_channel to silc_server_create_new_channel
1883 and added new function sicl_server_new_channel that handles the
1884 incoming New Channel packet. Added also new sending function
1885 silc_server_send_new_channel to send New Channel Payload.
1887 * Added new function silc_server_notify to process incoming notify
1888 packet to the server/router. Server may then relay the notify
1889 to clients if needed.
1891 * Added new function silc_server_new_channel_user to process incoming
1892 New Channel User packet. Router will redistribute the packet and
1893 send JOIN notify to its local clients and locally connected servers
1894 if needed. Normal server will send JOIN notify to its local client
1895 on same channel when received this packet. Added also corresponding
1896 sending function silc_server_send_new_channel_user to sent the
1899 * Added boolean route argument to send_notif_to_channel and
1900 packet_send_to_channel functions to attempt to route the packet
1901 if it is TRUE and send only locally if it is FALSE.
1903 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * silc_server_replace_id now broadcasts the received replace ID
1906 packet if it is not broadcast packet already. The router must
1907 broadcast to inform other routers about changed ID.
1909 * Added backpointer to server's router into SilcServer context in
1910 silcd/server_internal.h.
1912 * Fixed silc_server_packet_broadcast to send correct broadcast
1915 * The channel key is now distributed to the local client as soon
1916 as it is received from the router (in router environment) so that
1917 no other packet may be sent for the channel until client has
1920 * silc_server_remove_channel_user now broadcasts the received
1921 Remove Channel User packet if it is not broadcast packet already.
1922 The router must broadcast to inform other routers about removed
1925 * Added users field into SilcPacketContext that is a reference count
1926 of the context. One can increase the reference count by calling
1927 silc_packet_context_dup which is now changed to just increase the
1928 reference count instead of duplicating the data. The reference
1929 count is decresed by calling silc_packet_context_free that will
1930 free the data after the reference count hits zero.
1932 For now on the packet context and everything allocated into it
1933 (including the raw packet from network) must be freed by calling
1934 the new silc_packet_context_free function. Added also new function
1935 silc_packet_context_alloc that must be used now to allocate the
1936 context. This also means that if a routine is asynchronous from
1937 silc_[client/server]_packet_parse_type the packet context must
1938 be duplicated by calling silc_packet_context_dup. Otherwise it
1939 gets free'd after silc_[client/server]_packet_parse_type returns.
1940 Also, one must remember that if packet is duplicated then its
1941 reference count must be decresed by calling the free function as
1942 many times as it was duplicated.
1944 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1945 from both client and server.
1947 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Made joining to a channel working in router environment.
1951 * Cleaned up JOIN command on server side and create function
1952 silc_server_command_join_channel internal routine to make the
1955 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Changed silc_command_pending list to SilcDList. Also, added
1958 `ident' field to SilcServerCommandPending structure to identify
1959 the reply and to call correct callback.
1961 Added silc_server_command_pending_check function to replace the
1962 corresnponding macro. The silc_command_pending list is not
1965 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1966 to set identifier to previously allocated Command Payload. It
1967 is used to set identifier for command when resending Command
1970 * Added silc_command_payload_encode_payload to encode Command
1971 Payload buffer from SilcCommandPayload structure.
1973 * Added silc_argument_payload_encode_payload to encode Argument
1974 payload buffer from SilcArgumentPayload structure.
1976 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Changed WHOIS command to support router connection on server side.
1979 The whois request is always sent to router unless the server is
1980 standalone server. After server has received the reply from the
1981 router will it send the reply to the client.
1983 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1984 broadcast received broadcast packet. The function is used only
1985 by router. The broadcast packet is always sent to the router's
1988 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1989 render given ID to printable string, for log files for example.
1991 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Made basic router to router connections working. At least they
1994 can now connect to each other but nothing really works the way
1995 they are supposed - yet.
1997 * Added new initiator token to RouterConnection configuration
1998 file in silcd/serverconfig.[ch]. It is used to tell whether we
1999 are the initiator to the remote router or whether we'll expect
2000 the other end to connect.
2002 * Moved registering of listener task to silc_server_init, hence
2003 the server starts listenning as soon as it is run, even if it
2004 does not have connections to other routers. Let's see how well
2007 * Changed default connection retry timeouts for more suitable in
2010 * Removed cipher and such arguments from silc_idlist_add_client
2011 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2012 Added new function silc_idlist_add_data to add the keys and stuff
2015 * Added SilcIDListData structure and added it to SilcClientEntry
2016 and SilcServerEntry as their first field in the structure. This
2017 way we can explicitly cast the ID entries to the SilcIDListData
2018 structure and get common data for the entries. In past, we had
2019 to first check what type of connection it is and then cast it to
2020 correct ID entry type. Now, we can directly cast the opaque
2021 pointer to the SilcIDListData (no matter what ID entry it actually
2022 is) and get the data needed.
2024 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2027 in some circumstances even if threre were timeout tasks, though not
2028 IO tasks, but tasks anyway. Now fixed.
2030 * Defined SilcServerConnection structure to hold connection specific
2031 stuff about directly connected servers and routers. The definition
2032 is currently in silcd/server_internal.h. I thought about having
2033 a bit more important role fro this struct but for now it is used
2034 only when connecting to other server (or router actually).
2036 * Added connecting retry support in server when connecting to
2037 router(s). The retry feature implement exponential backoff
2038 algorithm. Also, added SilcServerParams structure to hold default
2039 parameters for server. For now, it include these retry settings
2040 and are hard coded. After server is moded to be as Silc Server
2041 Library this structure will be more important.
2043 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Changed client librarys channel->clients table to SilcList and
2046 changed code accordingly.
2048 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Changed client's channel table to SilcList and changed code
2051 accordingly. Also changed SilcChannelClientEntry to include back-
2052 pointer to the channel so that client entry can use that structure
2053 as list as well and we have fast cross-reference to the channel.
2054 This change dramatically decreased the complexity of channel
2055 handling with client entry and vice versa (removed one extra
2056 loop when searching for channel entry from many functions).
2058 * Changed server->sim from table to SilcDList and changed code
2061 * NAMES command can now be used from user interface. It will show
2062 the user list on the channel, neatly.
2064 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2065 Code now saves realname of the user if it becomes available.
2067 * Renamed configure.in to configure.in.pre and made ./prepare
2068 script to automatically add correct version string to
2069 configure.in which it creates from configure.in.pre.
2071 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * NAMES command reply now shows users mode with the nickname when
2076 * Moved silc_client_ch[u]mode[_char] functions from
2077 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2078 place sucks, they are utility functions and should be in some
2081 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2083 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2086 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added TRQ (efficient deque and list library) into lib/trq. This is
2091 a very good list library that is currently used in the SILC. Defined
2092 SilcList API over the library because I didn't like the API very
2093 much. See lib/trq/silclist.h for the API and examples of how to
2094 use the API. Fixed various places in the code to use the new
2095 SilcList API. The SilcList is meant for lists that has a structure
2096 already defined as a list. It is not suitable to add just some
2097 context to the list (in TRQ, the context is the list actually).
2099 So, I defined SilcDList that can be used for the purpose where
2100 predefined list structure does not exit. This can be used as
2101 such list. Now some context just can be added to the SilcDList.
2102 Currently this list is not used in the SILC just yet, though there
2103 are a lot places where this can replace dynamically allocated
2104 tables and I will fix these places, later, to use SilcDList.
2105 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2106 and use TRQ internally).
2108 Also fixed some annoying warning messages that the original TRQ
2109 code generated. Also minor changes to TRQ's Makefile.in.
2111 * Added support for querying by Client ID to both WHOIS and
2112 IDENTIFY commands into server, as required by the protocol.
2114 * Removed method function pointers from SilcBuffer structure. They
2115 weren't used to anything and just increased the context size for
2116 no good reason. This change also made silc_buffer_alloc and
2117 silc_buffer_free functions inline functions.
2119 * Disabled command flooding detection support until it's fixed so
2120 that it accepts commands in but does not execute them more than once
2123 * Added silc_net_localhost(), to return local hostname, into
2124 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2125 that must be initialized before calling silc_client_init.
2127 * Added new function: silc_server_send_notify_on_channels to send
2128 notify messages to all channels client has joined. It is assured
2129 that the message is sent only once per client.
2131 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2132 lib/silcutil/silcutil.[ch] as silc_format function. The new
2133 function is generic and is used by server as well, not only by
2134 the logging routines.
2136 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2137 the provided version string was not acceptable. Added new function:
2138 silc_ske_check_version into lib/silcske/silcske.h. The function
2139 must be implemented by the application (client or server) and it
2140 does not reside in the SKE library. The function checks the version
2141 string remote end sent.
2143 * Added back pointers (to opaque context and to SilcSocketConnection)
2144 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2146 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2147 duplicate packet context structure.
2149 * Changed `notify' client operation to send same arguments as client
2150 receives from server except for ID's. ID's are mapped to correct
2151 ID entry and that is returned. Also, if channel entry is not sent
2152 by server but the notify is for channel the channel entry is sent
2153 to application (otherwise application doesn't know that it is for
2154 channel (library gets it from packet's Destination ID)).
2156 * Added silc_client_remove_from_channels into client library to
2157 remove a client from all channels it has joined to. Used when
2158 received SIGNOFF notify from server. Added also new function
2159 silc_client_replace_from_channels to replace old ID entry with
2160 new ID entry on all channels. Used when received NICK_CHANGE
2163 * Fixed ID Cache list handling in silc_idlist_get_client in
2164 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2165 to get (or query) client by ID.
2167 * Updated TODO list.
2169 * Added connection authentication status message defined by the
2170 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2171 support for these into the code in client and server side.
2173 * Added generic function silc_client_send_command to send any command
2174 with variable argument list. Application should use this function
2175 to send commands if the command functions provided by the library
2176 does not suite for the application's user interface needs.
2178 * Added new `failure' client operation. Application is notified about
2179 received failure packet if client is executing a protocol. In this
2180 case the protocol's execution has failed.
2182 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2183 is required by the protocol.
2185 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2186 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2189 * Added status flag to SilcSKE object to indicate realtime status
2190 of the SKE protocol.
2192 * Application receives now exactly same command reply arguments as
2193 the library receives from server. However, if ID is received the
2194 corresponding ID entry is returned to the application (eg. Client
2195 ID is mapped to correct SilcClientEntry entry and that is returned).
2196 Changed command_reply client operation due to this change.
2198 * Changed all ID's in commands and in command replys as ID Payloads.
2199 Change affected both client and server side codes.
2201 All ID's sent in SILC network (with execption of ID's in SILC
2202 Packet header) are sent in ID Payload to support variable length
2205 * Server now notifies nick changes and notifies all clients on
2206 the channels about the new nickname (about the new Client ID,
2209 * Implemented CMODE command to change channel modes. Supports all
2210 channel modes defined by the protocol specs except ban and invite
2211 lists. (Also, private channel key mode is supported but support for
2212 setting private channel key in client is missing, thus, this mode
2213 has no effect on client side (except that server requires that the
2214 client uses private channel key and normal channel traffic does not
2217 Also, invite mode works per se, but INVITE command does not work
2218 yet correctly, so you can set channel as invite only channel but
2219 inviting clients to the channel does not work (it is yet to be
2220 thought what's the best way to do it).
2222 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2223 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2224 Implemented CUMODE command to change user's mode on the channel.
2225 Supports all modes defined by the protocol specs.
2227 * Added NAMES command reply to return users modes on the channel.
2229 * Removed unnecessary and slow ciphers from lib/silccrypt.
2231 * Set SO_KEEPALIVE option to connection sockets by default.
2233 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2235 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2236 redefined the Notify Payload into protocol specs.
2238 * Added silc_id_payload_parse_id to get ID directly from raw
2241 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2244 accept searching by Client ID as well.
2246 * Added support for LEAVE and SIGNOFF notify types in client library.
2248 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2249 to parse ID Payload from raw data.
2251 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Added flags parameter into silc_ske_assemble_security_properties
2254 function in lib/silcske/silcske.[ch].
2256 * Changed notify client operation to fit better for notify messages
2257 sent by server. The notify payload received from server is now
2258 passed to the application (after parsing it to SilcNotifyPayload).
2259 It is application's responsibility to retrieve the arguments
2260 from the payload and show the message the way it wants. The message
2261 sent by server is implementation specific.
2263 * Changed public keys to comply with the protocol specification.
2264 Old public keys are not supported anymore and are not compatible.
2266 * Removed nickname from Channel Payload as the latest draft removed
2267 it. The client must resolve the nickname from the NAMES command
2268 reply received when it joined the channel.
2270 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2272 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Fixed some errors in protocol specification drafts.
2276 * Created lib/silccore/silcnotify.c to implement Notify Payload
2277 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2278 generic payloads described by protocol specifications. The file
2279 includes implementations for ID Payload and Argument Payload.
2281 * Changed Command Payload implementation to use the new Argument
2282 Payload. Changed command_xxxx_payload to command_payload_xxxx
2283 to comply with SILC coding conventions.
2285 * Added suppport for Argument Payload handling in Notify Payload
2286 implementation as protocol requires it. Added the new support
2287 into server and client lib as well.
2289 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Added support for multiple nicknames on same channel. [n] is
2292 added locally to the nickname if there are more than one same
2293 nicknames on the channel.
2295 * Server now sends all nicknames that matched WHOIS request.
2296 Client also shows the list received from server.
2298 * Added TOPIC command to client side. User can now set and show
2299 current topic on channel.
2301 * Added MOTD command to client and server. Also, server sends the
2302 motd when client connects to the server.
2304 * Changed version strings to comply ISO 8601.
2306 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Fixed protocol error handling in client library. It should now
2309 cope even if the SKE fails for some reason.
2311 * Made new protocol specification drafts for submitting to IETF.
2313 * Implemented TOPIC command to server in silcd/command.c.
2315 * Added two new notify types into lib/silccore/silcnotify.h:
2316 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2317 notify nickname change and topic setting/change on a channel.
2319 * API change of command_reply operation in client library. The
2320 application gets now the status type received from server as well.
2322 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2326 * Cras fixed and optimized the packet handling even further and
2327 it should work now. Minor change to the prototype of function
2328 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2330 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added new function into lib/silcutil/silcschedule.[ch]:
2333 silc_schedule_with_fd to select() a specified fd. The function
2334 returns after timeout expires or data arrives or goes. The
2335 function is used by packet routines to wait that all data is
2336 received from network.
2338 * Fixed data reading from network in lib/silccore/silcpacket.c.
2339 The code now assures that all data is read from the fd and then
2340 continues packet processing. This was a bug fix since the code
2341 used to drop some data in some circumstances.
2343 * Added new function into lib/silcclient/client.[ch]:
2344 silc_client_start_key_exchange to start key exchange after
2345 connection has been established to server. The code internally
2346 now uses this funtion but its main purpose was to provide it
2347 for applications that perform their own connecting. After
2348 application has created a connection it merely calls this
2349 function to start the key exchange between client and server.
2350 The library takes care of everything else after that.
2352 Updated also lib/silcclient/README to explain the usage of
2355 * Do not send to application information that connection has
2356 been established. Application gets notified it by connect
2359 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Applied cras's patch to add silc_schedule_one function. The
2362 function runs scheduler once and returns.
2364 * Fixed the scheduler after cras messed it up. The timeout
2365 handling works now as it's supposed to work.
2367 * Added into lib/silccore/ silcnotify.h to include notify
2368 message types support. Changed silc_server_send_notify*
2369 functions, in server.[ch], to support those new notify types.
2370 Added the support for the notify types into client library,
2371 as well. Added new notify client operation into ops.h in
2374 * Changed silc_server_packet_send_to_channel to send normal
2375 packets instead of just channel message packets. The function
2376 is now used to send the notify packets to channels. It is not
2377 used to send channel message packets anymore, as server never
2380 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2381 va_arg()s as it seems to require it nowadays. I guess, if SILC
2382 is compiled with older va_arg() the new code should work anyway.
2384 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Splitted core library. Core library (lib/silccore) includes
2387 now only SILC protocol specific core (and common) components.
2388 Created new utility library (lib/silcutil) that includes more
2389 generic purpose stuff. The stuff for util library was taken
2390 from the old core library. This was minor and easy split.
2392 * Created SILC Client Library (lib/silcclient) that includes
2393 implementation of the SILC client without user interface. This
2394 was major move from silc/ directory. The code has been changed
2395 so that it is transparent towards the user interface. The
2396 silc/ directory includes now the same user interface as before
2397 and it uses the new client library. Read lib/silcclient/README.
2398 Basicly, the client library performs everything else related
2399 to SILC except user interface handling. Also, configuration
2400 files are considered to be part of user interface and library
2401 does not handle them.
2403 This change also changed a lot of structures, function naming etc.
2404 Most important change was that SilcClientWindow object was
2405 renamed to SilcClientConnection in the client library. Created
2406 also new file lib/silcclient/ops.h. Also added new files
2407 silc/local_command.[ch] and silc/client_ops.[ch].
2409 All these changes were made to make it easier for user interface
2410 designers to create what ever user interface for the SILC client
2413 It is also expected that the server will be moved to lib
2414 directory as well and SILC Server Library will be created;
2415 sometimes in the future.
2417 * Removed Local commands from lib/silccore/silccommand.h as
2418 they are application specific and new client library does not
2419 handle any of those anymore.
2421 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2422 old client implementation in silc/.
2424 * Added support for callback functions in SILC_LOG_* macros.
2425 Application can now set its own callbacks that will be called
2426 instead of using the default functions that will always print
2427 the debug messages to stderr (or stdout). Also, debugging can
2428 now be disabled by setting silc_debug to FALSE and re-enabled by
2429 setting it to TRUE. Note, that logging will still work even
2430 if debugging is disabled.
2432 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2433 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2434 silc_log_reset_debug_callbacks.
2436 * To enable debugging in silc client one must give now -d
2437 option on command line.
2439 * Changed silc_schedule_init to automatically allocate task queues
2440 if they are not allocated before calling it.
2442 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Added GMP 3.1 into math library.
2446 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2449 a channel in SILC network. The packet is used by servers and
2450 routers to notify other routers that user has left a channel.
2451 This little feature was missing until now. Added the feature
2452 to protocol specification as well.
2454 Added functions: silc_server_send_remove_channel_user and
2455 silc_server_remove_channel_user into server.[ch].
2457 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2458 lib/silccore/silcpacket.h. However, they are not implemented
2461 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Fixed joining to a channel and sending channel messages
2464 between server and router. The channel message sending should
2465 now work inside a cell.
2467 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Fixed the private message sending between server and router.
2470 The private message sending should now work inside a cell.
2472 * Added silc_server_replace_id into server.[ch] to replace
2473 existing ID in the SILC network.
2475 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2476 and silc_idlist_replace_server_id into idlist.[ch] in server.
2478 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Fixed the server to server connections. Server can again now
2481 connect to router. Router to router connections probably does
2484 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Added dynamic protocol registering support. Now protocols can
2487 registered and unregistered on the fly. Patch by cras.
2489 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added lib/contrib directory to hold routines that some platforms
2492 don't have but are needed by SILC.
2494 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2495 into lin/contrib to provide getopt() and getopt_long() for
2496 those who don't have it.
2498 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Added AWAY command to client. When away message is set and
2501 client receives a private message packet the client automatically
2502 replies to the sender with the away message.
2504 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2505 bug seemed to be the cause of recent problems when compiling
2508 * Added version detection support to SKE protocol specification
2509 and added the new changes to the SKE implementation as well.
2510 There were other minor changes in the SKE protocol as well.
2512 Many changes in lib/silcske/silcske.[ch] and in
2513 lib/silcske/payload.[ch].
2515 * Added ^U functionality, clear input line. Patch from cras.
2517 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Mainly small bugfixes on core library. Fixed some debugging
2520 logging and buffer overflow in silclog.c.
2522 * Updated config.sub and config.guess on the distribution tree.
2524 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Added command lagging support in server. Client may execute
2527 commands now only once in two seconds.
2529 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Optimized packet reception. MAC computation and checking is now
2532 also more optimized. A lot previously duplicated code is now
2533 used as generic by both client and server.
2535 * Fixed key pair generation in clientutil.c
2537 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Added into lib/silccore/silcbufutil.[ch] new function;
2540 silc_buffer_realloc.
2542 * Moved generic packet sending/encryption functions to
2543 lib/silccore/silcpacket.[ch] from client and server. Some
2544 rewriting of the functions.
2546 * Moved all generic packet reception/decryption functions to
2547 lib/silccore/silcpacket.[ch] from client and server. The
2548 packet processing is now much cleaner in both client and server.
2549 These were major changes in both client and server.
2551 * Created many common functions in server to do packet sending.
2552 Previously code were duplicated a lot, this has been removed
2555 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Rewrote major parts of the ID cache system. Don't know
2558 whether it is better now or not but at least the API is more
2561 * Major rewrite on ID cache stuff on client because of the ID
2562 cache API changes. Added idlist.c to client.
2564 * Also major rewrite on ID cache stuff on server as well.
2565 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2566 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2567 in hand, instead they are all put into the ID cache system now.
2568 All server_idlist_* routines uses ID cache now instead of
2569 traversing its own lists (those lists does not exist anymore).
2570 SilcIDList though still exists. Also, SilcXXXEntry's are
2573 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Finally made the SKE implementation compliant to the protocol
2576 specification. All mp integers are now binary encoded as
2577 opposed being HEX encoded.
2579 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2582 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2583 functions: silc_[encode/decode]_pem. Also added function
2584 silc_encode_pem_file to PEM encode with newlines ('\n') for
2587 * SILC public keys are now encoded either PEM or binary. Same
2588 option is for private keys as well. By default private keys
2589 are binary encoded and public keys PEM encoded. Silly HEX
2590 encoding were removed.
2592 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2593 function to create fingerprints.
2595 * Fixed a bug in SHA1; does not change the original data anymore.
2597 * Partly implemented INFO command on client and server side.
2598 Fixed CLEAR command. Changes to SERVER command; show current
2599 server(s) when giving command without arguments. Added
2600 VERSION command to client.
2602 * Added check to server that unregistered connections cannot
2603 execute commands (unless it is specificly allowed).
2605 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Fixed screen refresh.
2609 * Fixed channel joining bug from client. On some circumstances
2610 client tried to join to a channel it had already joined.
2612 * Added public key verification process into client's protocol.c.
2613 The client now verifies the public key from user and saves
2614 it into ~./silc/serverkeys/ directory.
2616 Added into: clientutil.[ch]: silc_client_verify_server_key.
2618 * Changed SKE protocol's silc_ske_initiator_finish function
2619 to accept callback function that verifies the received public
2620 key. Removed old silc_ske_verify_public_key function.
2622 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2625 silc_pkcs_private_key[_data]_set.
2627 * Made the password and public authentication more cleaner in
2628 server's protocol.c.
2630 * Removed historic and obsolete protocol `channel_auth' from
2631 both client and server.
2633 * Removed wrong way of sending command status messages from
2634 server to client in server's command.c. The old way violated
2635 protocol specification.
2637 Changes to silccore/silccommand.[ch]: removed
2638 silc_command_encode_status_payload -> not needed anymore,
2639 changed silc_command_encode_payload_va to accept extra
2640 argument on variable argument list. The argument type must
2641 now be provided to the function. Also, added new function:
2642 silc_command_encode_reply_payload_va which is same as
2643 normal command_encode_payload_va except command status type
2644 is provided as extra argument.
2646 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added ~./silc directory handling. The directory includes the
2649 public and private keys for the client.
2651 Added silc_client_check_silc_dir, silc_client_create_identifier
2652 and silc_client_load_keys.
2654 * Implemented SILC protocol compliant public key. Added public
2655 and private key saving to and loading from files.
2657 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2658 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2659 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2660 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2661 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2663 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2664 silc_pkcs_load_[public/private]_key.
2666 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added silc_server_get_route (route.[ch]) to get connection
2669 data for the fastest route for given ID.
2671 * Implemented INVITE command on client and server. The command
2672 were re-defined in the SILC Protocol Specification and the
2673 implementation now complies with the specification.
2675 * Implemented PING command on client and server.
2677 * Implemented NAMES command on client and server. The server side
2678 supports currently only normal server not router server yet.
2679 Some changes to NAMES definition in SILC protocol specification.
2681 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Implemented LEAVE command on client and server.
2685 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2686 again. This change was made to the protocol as well. Server
2687 should not violate the protocol specification anymore.
2689 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2692 was tested. SOCKS4 was not but should work anyway.
