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 * Removed silc_idlist_find_client_by_nickname from the server.
15 Not needed anymore. Affected files silcd/idlist.[ch].

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

69 * Added function silc_string_match to regex match two strings.
70 Affected files lib/silcutil/silcutil.[ch].
72 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Redefined parts of the SilcChannelEntry in the server to support
75 the new ban and invite lists.
77 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
79 * Redefined the INVITE command. The same command can be used to
80 invite individuals to the channel but also to manage the invite
81 list of the channel (to add to and remove from the invite list).
82 Updated the protocol specs.
84 * Added new command SILC_COMMAND_BAN that can be used to manage
85 the ban list of the channel. Updated the protocol specs.
87 * Removed the channel modes: the SILC_CMODE_BAN and the
88 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
89 in the CMODE command. The equivalent features are now available
90 using INVITE and BAN commands. Updated the protocol specs.
92 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
93 in the network about change in the current ban list. The notify
94 type is not used by the client.
96 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
97 support the invite lists.
99 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Added new function silc_string_regexify that converts string
102 including wildcard characters into regex string that can
103 be used by the GNU regex library. Added into the file
104 lib/silcutil/silcutil.[ch].
106 Added silc_string_regex_combine to combine to regex strings
107 into one so that they can be used as one regex string by
108 the GNU regex library. Added into the file
109 lib/silcutil/silcutil.[ch].
111 Added silc_string_regex_match to match two strings. It returns
112 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
114 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Imported GNU regex to the soruce tree into lib/contrib.
117 Fixed some compiler warning from the regex.c.
119 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Fixed MOTD command in the server to work in router environment.
123 * Fixed the MOTD command in the client library to support
124 the server argument in the command.
126 * Added `nickname_len' argument to the silc_idlist_add_client
127 in the server, as the `nickname' argument may be binary data
130 * Added silc_idlist_get_channels to return all channels from
133 * Implemented LIST command to the server. Affected file is
136 * Implemented the LIST command to the client library and on the
139 * Added [<user count>] argument to the LIST command reply.
140 With private channels the user count is not shown.
142 * Updated TODO and README.
144 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * The client entry's data.registered must be TRUE even with
147 global client entry on global client list. The data.registered
148 is used to check whether the client is anymore in the network,
149 for example with WHOWAS command so it must be valid.
151 * Fixed the WHOWAS command in the server. It now actually works
152 in router environment. Added function into silcd/command_reply.c
153 silc_server_command_reply_whowas_save.
155 * Added silc_idlist_purge function to the silcd/idlist.c
156 to periodically purge the ID Cache.
158 * Fixed INFO command in the server. It works now in router
159 environment. Added <server name> argument to the INFO command
160 reply. Updated the protocol specs.
162 * Fixed minor bug in silc_idcache_purge to not purge if the
163 expire value is zero.
165 * Fixed various bugs in WHOIS and IDENTIFY command handling as
166 they were buggy because of the WHOWAS information.
168 * Fixed local command MSG to handle the async resolving of
169 the remote client properly. It used to fail the first MSG.
170 Affected file silc/local_command.c.
172 * Added `data_len' field to SilcIDCache context.
174 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Update TODO. Todo in commands in the server.
178 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
181 used by routers as broadcast packet to inform other routers
182 about the changed user mode.
184 Implemented the notify handling in the server. Affected file is
185 silcd/packet_receive.c. Added the function
186 silc_server_send_notify_umode to the silcd/packet_send.[ch].
188 * Added new generic Channel Payload and deprecated the New Channel
189 Payload. The New Channel Payload is now the generic Channel
192 * Added new argument `mode' to the silc_server_send_new_channel
193 as it is required in the Channel Payload now.
195 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
196 and created a new and real SilChannelPayload to represent the
197 new generic Channel Payload. Implemented the encode/decode
198 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
200 * Added silc_server_get_client_channel_list to return the list
201 of channels the client has joined for WHOIS command reply.
202 Affected file silcd/server.[ch].
204 * Implemented the channel list sending in the WHOIS command reply
205 in server and in the client.
207 Implemented the channel list displaying on the user interface
208 as well. Affected file silc/client_ops.c.
210 * Added silc_channel_payload_parse_list to parse list of Channel
211 Payloads. It returns SilcDList list of SilcChannelPayloads.
212 Client for example can use this function to parse the list of
213 channels it receives in the WHOIS command reply. The caller
214 must free the list by calling silc_channel_payload_list_free.
215 Affected files lib/silccore/silcchannel.[ch].
217 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Added one new argument <user mode> to the WHOIS command reply
220 to return the mode of the user in SILC. Updated the protocol
223 Implemented it to the server and client.
225 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Fixed the mode printing on the user interface on joining.
228 Affected file silc/client_ops.c.
230 * Implemented the UMODE command and user modes in general to the
231 client library and to the user interface.
233 * Implemented the UMODE command to the server.
235 * The server now sends UNKNOWN_COMMAND error status if client sends
236 unknown command. Affected file silcd/command.c.
238 * All server commands now handle the command identifier the right
239 way when sending the command reply to the client. The client can
240 use to identify the command replies with the identifier.
242 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Added silc_server_get_client_route to resolve the route to
245 the client indicated by the client ID. Affected file is
248 * Added silc_server_relay_packet as general function to relay
249 packet to arbitrary destination. This deprecates functions
250 like _send_private_message_key, _relay_notify etc. Affected
251 file is silcd/packet_send.[ch].
253 Removed silc_server_send_key_agreement,
254 silc_server_send_private_message_key and
255 silc_server_packet_relay_notify functions from the file
256 silcd/packet_send.[ch].
260 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
261 server. Affected file silcd/packet_receive.[ch].
263 * Implemented the KILL command to the client. Implemented the
264 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
265 Affected files lib/silcclient/command[_reply].c and
266 lib/silcclient/client_notify.c. Implemented the KILL notify
267 printing in the user inteface.
269 * Fixed a lot silc_parse_nick memory leaks from the client
270 library in the file lib/silcclient/command.c.
272 * Changed the silc_server_send_notify_on_channels's `sender'
273 argument from SilcSocketConnection to SilcClientEntry to
274 check the sender as entry and not as connection object and not
275 to send to the client provided as argument. The affected file
276 is silcd/packet_send.[ch].
278 * The notify packets that are destined directly to the client used
279 to not to be processed by the server. Now changed that and the
280 server processes all notify packets. After relaying the packet
281 to the client the notify packet is processed in the server.
283 * The silc_server_free_client_data now checks whether there is
284 pending outgoing traffic for the client and purges the data to
285 the network before removing the client entry.
287 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
290 an client is killed from the SILC Network. Updated the protocol
293 Added new function silc_server_send_notify_killed to the
294 silcd/packet_send.[ch].
296 * Added function silc_server_packet_relay_notify to relay notify
297 packets that are destined directly to a client. In this case
298 the server does not process the notify packets but merely relays
299 it to the client. Affected file silcd/packet_send.[ch].
301 Added also silc_server_packet_process_relay_notify to check
302 whereto relay the notify. Affected file is
303 silcd/packet_receive.[ch].
305 * Implemented the KILL command to the server.
309 * Added the backup schema desgined last fall to the protocol
310 specs for everyone to see. The specification is in the
311 *-spec-xx.txt draft and the packet type definitions for the
312 backup routers is in *-pp-xx.txt draft. Thusly, added also
313 new packet type SILC_PACKET_CELL_ROUTERS.
315 * A big security problem in the implementation discovered. The
316 signoff of an client did not cause new channel key generation
317 which it of course should've done. The channel keys must be
318 always re-generated when client leaves (or signoffs) the channel.
319 The silc_server_remove_from_channels funtion now handles
320 the channel key re-generation.
322 * Added `sender' argument to the silc_server_send_notify_on_channels
323 to not to send the client provided as argument. Affected file
324 silcd/packet_send.[ch].
326 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Implemented OPER and SILCOPER commands into the server and
331 * Added silc_auth_verify and silc_auth_verify_data to verify
332 the authentication directly from the authentication payload.
333 It supports verifying both passphrase and public key based
334 authentication. Affected file lib/silccore/silcauth.[ch].
336 * Added `hash' field to the SilcIDListData structure. It is the
337 hash negotiated in the SKE protocol. Affected file is
340 * Slight redesigning of the SilcAuthPayload handling routines.
341 Do not send SilcPKCS but SilcPublicKey as argument.
343 * Implemented the public key authentication support to the
344 serverconfig. The public key is loaded fromthe provided path
345 and saved as authentication data to void * pointer. Thus,
346 changed the unsigned char *auth_data to void *auth_data;
348 * Fixed SHUTDOWN command to send the reply before the server
349 is shutdown. :) Affected file silcd/command.c.
351 * Fixed fatal bug in CONNECT command. The hostname was invalid
352 memory and server crashed. Affected file silcd/command.c.
354 * Fixed fatal bug in CLOSE command. The server_entry became
355 invalid but was referenced later in the command. Affected file
358 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Fixed fatal bug in failure packet handling. Server ignored
361 the failure and thus crashed when it came.
365 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
368 that the command may be executed only once in (about) 2 seconds.
369 The old SILC_CF_LAG flag is same but allows command bursts up
370 to five before limiting.
372 Added the support for CF_LAG and CF_LAG_STRICT flags to the
373 server code. Various commands now includes the CF_LAG_STRICT
374 flag to disallow any kind of miss-use of the command.
376 * Fixed the silc_buffer_unformat to not to allocate any data
377 if the length of the data is zero. It used to allocate the
378 length + 1. Affected file lib/silcutil/silcbuffmt.c.
380 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Changed the format of AdminConnection configuration section
383 in the server. Added username of the admin to the format.
384 Affected files silcd/serverconfig.[ch].
386 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
387 to return admin configuration data by host, username and/or
390 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Implemented WHOWAS command to the server. Added the functions:
394 silc_server_command_whowas_parse,
395 silc_server_command_whowas_send_reply,
396 silc_server_command_whowas_from_client and
397 silc_server_command_whowas_from_server
399 * Added <Client ID> argument to the WHOWAS command reply. Updated
400 the protocol specs accordingly.
402 * Implemented WHOWAS command and command_reply to the client
405 Implemented the WHOWAS printing on the user interface.
407 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * Added new argument to the WHOWAS command reply, the real name.
410 It is an optional argument. Updated the protocol specs.
412 * Added SilcIDCacheDestructor callback that is registered when
413 the SilcIDCache is allocated. The callback is called when
414 an cache entry in the ID Cache expires, or is purged from the
415 cache. Added into lib/silccore/idcache.[ch].
417 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
418 to destruct the client entries when the cache entry expires.
419 Other ID Cache's in server and in the client library ignores
422 * If the ID Cache entry's `expire' field is zero then the entry
423 never expires. Added boolean `expire' argument to the
424 silc_idcache_add function in the lib/silccore/idcache.[ch].
425 If it is TRUE the default expiry value is used.
427 * Added silc_server_free_client_data_timeout that is registered
428 when client disconnects. By default for 5 minutes we preserve
429 the client entry for history - for WHOWAS command.
431 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Added support to the server to enforce that commands are not
434 executed more than once in 2 seconds. If server receives
435 commands from client more frequently, timeout is registered
436 to process the commands. Affected file silcd/command.c.
437 Added new function silc_server_command_process_timeout.
439 * Changed NICK_NOTIFY handling in client library to check that
440 if the client's nickname was changed, so there is no need to
441 resolve anything from the server.
443 * Removed error printing from the WHOIS and IDENTIFY commands.
444 If error occurs then it is ignored silently in the client library.
445 The application, however, may map the received error to
446 human readable error string. The application currently maps
447 the NO_SUCH_NICKNAME error to string.
449 * Made the command status message public to the application. Moved
450 them from lib/silcclient/command_reply.c to
451 lib/silcclient/command_reply.h. The application can map the
452 received command status to the string with the
453 silc_client_command_status_message function.
455 * Added check to the server to check that client's ID is same
456 as the Source ID in the packet the client sent. They must
459 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Added dist-bzip hook to the Makefile.am to make bzip2
462 compressed distributions.
464 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
466 * Server now enforces the maximum length for the nickname and
467 the channel as protocol specification dictates. 128 bytes for
468 nickname and 256 bytes for channel name.
470 * Moved the WHOIS printing to the application. The client libary
471 does not print out the WHOIS information anymore, the application
472 must do it. Renamed silc_client_command_reply_whois_print to
473 the silc_client_command_reply_whois_save.
475 The client's idle time is also sent to the application now, and
476 the idle is shown on screen.
478 * Added silc_client_command_reply_identify_save to save the
479 received IDENTIFY entries.
481 * Do not check for channel private keys in message sending and
482 reception if the channel does not have the PRIVKEY mode set.
483 Affected file lib/silclient/client_channel.c.
485 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
488 just surfaced after chaning the JOIN procedure.
490 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Added silc_client_get_clients_by_list to get client entries
493 from Client ID list, that is returned for example by JOIN
494 and USERS command replies. The application should use this
495 function for example when JOIN command reply is received to
496 resolve the clients already on the channel (library does not
497 do that anymore as USERS command reply is not used in the JOIN
498 procedure anymore). Affected files lib/silcclient/silcapi.h and
499 lib/silcclient/idlist.c.
501 * JOIN command reply and USERS command reply returns now SilcBuffer
502 pointers instead of unsigned char pointers when returning
503 the client list and mode list.
505 * Added <Client ID> argument to the JOIN command reply, mainly
506 for the server to identify for which client the command was
507 originally sent. Updated protocol specs accordingly.
509 * Added SilcDlist private_key pointer to the SilcChannelEntry
510 in the client to support the channel private keys. Affected
511 file is lib/silcclient/idlist.h.
513 * Added SilcChannelPrivateKey argument to the function
514 silc_client_send_channel_message so that application can choose
515 to use specific private ke if it wants to. If it is not provided,
516 the normal channel key is used, unless private keys are set.
517 In this case the first (key that was added first) is used
518 as the encryption key.
520 * Implemented the support for channel private key handling.
521 Implemented the following functions:
523 silc_client_add_channel_private_key,
524 silc_client_del_channel_private_keys,
525 silc_client_del_channel_private_key,
526 silc_client_list_channel_private_keys and
527 silc_client_free_channel_private_keys
529 Affected file lib/silcclient/client_channel.c.
531 * Added the support for the private keys in the channel message
532 sending and encryption and in the message reception and
533 decryption. Affected funtions are
534 silc_client_send_channel_message and silc_client_channel_message.
536 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Added SKE's key verify callback to the client library's
539 KE protocol context. Affected files lib/silcclient/protocol.[ch].
541 * Removed the statement that server (or router) must send USERS
542 command reply when joining to the channel so that the client
543 knows who are on the channel. Instead, the client list and
544 client's mode list is now sent in the JOIN command reply to the
545 client who joined channel. This is better solution.
547 * Added function silc_server_get_users_on_channel and function
548 silc_server_save_users_on_channel to the silcd/server.[ch].
550 * Removed function silc_server_command_send_users from the
553 * Do not show topic on the client library anymore. The topic is
554 sent in the command reply notify to the application and the
555 application must show the topic now.
557 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added client searching by nickname hash into the IDENTIFY and
560 WHOIS commands in the server as they were clearly missing from
561 them. Affected file is silcd/command.c.
563 * Fixed a bug in private message receiving in the client library.
564 The remote ID was freed and it wasn't supposed, now it is
567 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Minor fix to the channel payload; allocate the data area, as it
570 needs to be of specific length.
572 * If the key agreement port is zero then the operating
573 system will define the bound port. Affected files are
574 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
576 * Added new function silc_channel_payload_decrypt into the file
577 lib/silccore/silcchannel.[ch].
579 * Moved the channel message etc, check from silc_packet_decrypt
580 to applications. The library calls now a generic
581 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
582 when the packet is either normal or special. This was done to
583 allow more wide range of checking that was not allowed when
584 the code was in library. Now applications can do virtually any
585 checks to the packet and return to the library the decision how
586 the packet should be processed. Affected files are
587 lib/silccore/silcpacket.[ch].
589 Added silc_server_packet_decrypt_check to the server and
590 silc_client_packet_decrypt_check to the client library.
592 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
593 to send with specified source and destination information.
595 * Channel message delivery between routers was broken after the
596 channel key distribution was fixed earlier. The channel key
597 was used be to distributed to other routers as well which is not
598 allowed by the protocol. Now this is fixed and channel keys
599 really are cell specific and the channel message delivery between
600 routers comply with the protocol specification.
602 * Fixed various commands in server to check also the global list
603 for the channel entry and not just the local list. The affected
604 file silcd/command.c.
606 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Added assert()s to buffer formatting and unformatting routines
609 to assert (if --enable-debug) when error occurs. Affected
610 file: lib/silcutil/silcbuffmt.c.
612 * Changed to auto-reconnect to check whether the remote host is
613 router and register the re-connect timeout if it is. It used
614 to check that whether we are normal server, but router must do
615 auto-reconnect with another router as well. Affected file
618 * Removed the [<key len>] option from CMODE command as the cipher
619 name decides the key length, nowadays. See the defined ciphers
620 from the protocol specification.
622 * Added [<hmac>] option to the CMODE command to define the HMAC
623 for the channel. Added SILC_CMODE_HMAC channel mode.
625 * Added [<hmac>] option for the JOIN command so that user can
626 select which HMAC is used to compute the MACs of the channel
629 * Added Hmac field to the Channel Message Payload. The integrity
630 of plaintext channel messages are now protected by computing
631 MAC of the message and attaching the MAC to the payload. The
632 MAC is encrypted. Now, it is clear that this causes some
633 overhead to the size of the packet but rationale for this is that
634 now the receiver can verify whether the channel message decrypted
635 correctly and also when private keys are set for the channel the
636 receiver can decrypt the packet with several keys and check from
637 the MAC which key decrypted the message correctly.
639 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
640 lib/silccrypt/silccipher.[ch].
642 * Added silc_hash_len to return the digest length into the
643 lib/silcrypt/silchash.[ch].
645 * Rewrote parts of Silc Channel Payload interface in the
646 lib/silccore/silcchannel.[ch]. The encode function now also
647 encrypts the packet and parse function decrypts it.
649 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed a minor formatting bug in the SKE's key material processing.
652 It actually might have processed the keys wrong way resulting
655 * Redefined the mandatory HMAC algorithms and added new algorithms.
656 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
657 and hmac-md5 truncated to 96 bits. The mandatory is now
658 hmac-sha1-96. Rest are optional (including the one that used
659 to be mandatory). Rationale for this is that the truncated HMAC
660 length is sufficient from security point of view and can actually
661 make the attack against the HMAC harder. Also, the truncated
662 HMAC causes less overhead to the packets. See the RFC2104 for
665 * Added new [hmac] configuration section. The SKE used to use
666 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
667 is of course wrong. The official names that must be proposed in
668 the SKE are the ones defined in the protocol specification
669 (hmac-sha1-96 for example). The user can configure any hmac
670 using any hash function configured in the [hash] section. At
671 least, the mandatory must be configured.
673 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
675 * Added HMAC list to the SKE proposal list. It has now both
676 hash algorithm list and HMAC list. This makes the protocol
677 incompatible with previous versions. The SKE now seems to work
678 the way it is supposed to work, for the first time actually.
680 * Defined plain Hash algorithms to the protocol specification.
683 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
685 * Implemented support for key agreement packets into the server.
686 Added functions silc_server_key_agreement and
687 silc_server_send_key_agreement. Other than these functions,
688 server has nothing to do with this packet.
690 * Added support for private message key packets into the server.
691 Added functions silc_server_private_message_key and
692 silc_server_send_private_message_key.
696 * Changed the silc_[client|server]_protocol_ke_set_keys to be
697 called in the protocol's final callback instead in the END
698 protocol state. This makes a little more sense and in the same
699 time in client we can use the same protocol routines for normal
700 key exchange and to key agreement packet handling as well.
702 * Added to both client's and server's KE protocol context the
703 SilcSKEKeyMaterial pointer to save the key material. We will
704 bring the key material to the protocol's final callback by doing
705 this. The final callback must free the key material.
707 * Added SKE's packet_send callback into client's KE protocol
708 context so that the caller can choose what packet sending function
709 is used. This way we can use different packet sending when
710 doing normal SKE when doing key agreement packet handling (in
711 the key agreement packet handling we do not want to encrypt
714 * Implemented the responder side of the key agreement routines
715 in the client. The client can now bind to specified port and
716 accept incoming key negotiation. The key material is passed
717 to the application after the protocol is over.
719 * Implemented the processing of incoming Key Agreement packet
720 in the client. Added function silc_client_key_agreement to
723 * Implemented the intiator side of the key agreement routines
724 in the client. The client can now initiate key agreement with
725 another remote client. The key material is passed to the
726 application after the protocol is over.
728 * Created client_keyagr.c to include all the key agreement
731 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
732 SILC_TASK_CALLBACK except that it is not static.
734 * Created client_notify.c and moved the Notify packet handling
735 from the client.[ch] into that file.
737 * Created client_prvmsg.c and moved all private message and
738 private message key routines from the client.[ch] into that file.
740 * Create client_channel.c and moved all channel message and
741 channel private key routines from the client.[ch] into that file.
743 * Changed silc_client_get_client_by_id_resolve to resolve with
744 WHOIS command instead of IDENTIFY command, in the file
745 lib/silclient/idlist.c.
747 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Implemented the SKE's responder side to the Client library.
751 * When FAILURE is received to the protocol do not trust it
752 blindly. Register a timeout to wait whether the remote closes
753 the connection as it should do it, only after that process the
754 actual failure. This was changed to both client and server.
756 * Added client_internal.h to include some of the structures
757 there instead of client.h in lib/silcclient/.
759 * Added function silc_task_unregister_by_callback to unregister
760 timeouts by the callback function.
762 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Some "Incomplete WHOIS info" errors has been appearing on the
765 log files. Took away the entry->userinfo check from WHOIS
766 reply sending. The entry->userinfo is now " " if client did not
767 provide one. I thought this was fixed earlier but something
768 is wrong still. Let's see if the error still appears.
770 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Fixed a minor bug in the login when the channel key is
773 re-generated in the server. It used to generate the key in
774 wrong order and thus caused problems in the channel traffic.
776 * Fixed a minor bug in channel key distsribution after
777 KICK command. The key was not sent to the router even though
780 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Added silc_ske_process_key_material_data as generic routine
783 to process any key material as the SILC protocol dictates. The
784 function is used by the actual SKE library but can be used by
785 applications as well. This relates to the private message keys
786 and the channel private keys since they must be processed the
787 same way the normal SILC session keys. The protocol dictates
788 this. Affected files: lib/silcske/silcske.[ch].
790 Added also silc_ske_free_key_material to free the
791 SilcSKEKeyMaterial structure.
793 * Defined silc_cipher_set_key function to set the key for
794 cipher without using the object's method function. The affected
795 files: lib/silccrypt/silccipher.[ch].
797 * Implemented silc silc_client_add_private_message_key,
798 silc_client_add_private_message_key_ske,
799 silc_client_del_private_message_key,
800 silc_client_list_private_message_keys and
801 silc_client_free_private_message_keys functions in the
804 Added functions silc_client_send_private_message_key to send
805 the Private Message Key payload and silc_client_private_message_key
806 to handle incoming Private Message Key payload.
808 * Added Cipher field to the Private Message Key payload to set
809 the cipher to be used. If ignored, the default cipher defined
810 in the SILC protocol (aes-256-cbc) is used.
812 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Removed lib/silcclient/ops.h file.
816 Redefined parts of the SILC Client Library API. Created new
817 file silcapi.h that deprecates the ops.h file and defines the
818 published Client Library API. Defined also private message key
819 API and channel private key API into the file.
821 This is the file that the application must include from the
822 SILC Client Library. Other files need not be included by
823 the application anymore.
825 * Added new key_agreement client operation callback and also
826 defined the Key Agreement library API for the application.
828 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
830 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
831 is used by clients to request key negotiation between another
832 client in the SILC network. If the negotiation is started it
833 is performed using the SKE protocol. The result of the
834 negotiation, the secret key material, can be used for example
835 as private message key.
837 Implemented the Key Agreement payload into the files
838 lib/silccore/silauth.[ch].
840 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * Redefined ciphers for the SILC protocol. Added some new ciphers
843 and defined the key lengths for the algorithms. Changed the
844 code accordingly. The default key length is now 256 bits.
846 * Fixed SKE key distribution function silc_ske_process_key_material
847 when the key length is more than 128 bits. The default key
848 length in SILC is now 256 bits.
850 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
851 to indicate unsupported algorithm.
853 * Renamed rijndael.c to aes.c and all functions as well.
855 * Fixed a long standing channel key setting bug in client library.
856 Weird that it has never surfaced before.
858 * Fixed bug in channel deletion. If the entire channel is removed
859 then it must also delete the references of the channel entry
860 from the client's channel list as the client's channel entry and
861 the channel's client entry share same memory.
863 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Implemented CONNECT and SHUTDOWN commands in the client.
867 * Implemented CLOSE command to the client.
869 * Added the function silc_idlist_find_server_by_name into the
870 files silcd/idlist.[ch].
872 Added the function silc_idlist_find_server_by_conn into the
873 files silcd/idlist.[ch].
875 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * DIE command was renamed to SHUTDOWN. Updated the both code
880 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
881 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
883 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
886 * Added function silc_server_create_connection function to create
887 connection to remote router. My server implementation actually
888 does not allow router to connect to normal server (it expects
889 that normal server always initiates the connection to the router)
890 so the CONNECT command is only good for connecting to another
893 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
896 or some other client was kicked from the channel.
898 Implemented the handling of the notify type to both client
901 Implemented silc_server_send_notify_kicked to send the KICKED
902 notify. It is used to send it to the server's primary router.
904 * Implemented the KICK command into server and client.
906 * Added `query' argument to the silc_idlist_get_client function
907 to indicate whether to query the client from server or not if
910 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
911 to indicate that the client is not channel founder.
915 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Removed the rng context from SilcPacketContext structure and
918 changed that the packet routine uses the Global RNG API.
920 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added support for quit message that client can "leave" on the
923 channel when it quits the SILC. It is ditributed inside the
924 SILC_NOTIFY_TYPE_SIGNOFF notify type.
926 Added silc_server_free_client_data that will take the
927 signoff message as argument.
929 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
931 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Updated parts of the protocol specification to keep it up
936 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
939 payloads in one packet.
941 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
942 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
943 use now the new List flag.
945 * Also deprecated the following packet types: REPLACE_ID,
946 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
948 * Added list support for Notify packet in server.
950 * Added silc_server_send_notify_channel_change to send the
951 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
952 the silc_server_send_replace_id.
954 * Added silc_server_send_notify_nick_change to send the
955 NICK_CHANGE notify type. Deprecates the function
956 silc_server_send_replace_id.
958 * Added silc_server_send_notify_join to send the JOIN notify type.
959 Deprecates the function silc_server_send_new_channel_user.
961 * Added silc_server_send_notify_leave to send LEAVE notify type.
962 Deprecates the function silc_server_send_remove_channel_user.
964 * Added silc_server_send_notify_cmode and
965 silc_server_send_notify_cumode to send CMODE and CUMODE notify
966 types. Deprecates the silc_server_send_set_mode function.
968 * Added SERVER_SIGNOFF notify type to indicate that server has
969 quit. This means that all clients on the channel from that
970 server will drop. This can be also used when netsplit happens.
972 Deprecated REMOVE_ID packet type since it is not needed anymore
975 Added silc_server_send_notify_server_signoff to send the
976 SERVER_SIGNOFF notify type. Deprecates the function
977 silc_server_send_remove_id.
979 Added also silc_server_send_notify_signoff to send the
982 * Employed the PKCS #1. It is the mandatory way to do RSA in the
983 SILC protocol from this day on. Changed the protocol
984 specification as well.
986 * Added silc_server_send_notify_topic_set to send TOPIC_SET
987 notify type. It is used between routers to notify about
988 topic changes on a channel.
990 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
993 * Partly updated the protocol specification to comply with the
994 changes now made. It is still though a bit outdated.
996 * The JOIN notify type now takes one extra argument <Channel ID>.
997 The packet used to be destined to the channel but now the
998 JOIN type may be sent as list thus it is impossible to
999 destine it to any specific channel. By adding this argument
1000 it is again possible.
1002 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1004 * Added CREDITS file. The CHANGES and CREDITS file will appear
1005 in the distribution as well.
1007 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1010 types in the server's silcd/packet_receive.c.
1012 * Implemented CMODE and CUMODE to work in router environment.
1014 * Fixed minor encoding and decoding buglet from the
1015 lib/silccore/silcmode.c.
1017 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1020 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1022 * Changed all SilcConfigServer* and silc_config_server* to
1023 SilcServerConfig* and silc_server_config*, respectively.
1026 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Associated the ID (client or server ID) to the Authentication
1029 Payload to avoid any possibility of forging. Updated the
1030 protocol specification and the code accordingly.
1032 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * The RSA key length is now save to the RsaKey context in the
1035 key generation process in lib/silccrypt/rsa.c. The key length
1036 is now used to figure out the maximum size of the block allowed
1037 to be encrypted/signed.
1039 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1040 is equivalent to the silc_mp_mp2bin but does not allocate any
1043 * Changed silc_mp_mp2bin API to take length argument. If it is
1044 non-zero then the buffer is allocated that large. If zero, then
1045 the size is approximated using silc_mp_sizeinbase, which however
1048 * Created Global RNG API which is global RNG that application can
1049 initialize. After initializing, any routine anywhere in the
1050 code (including library) can use RNG without allocating a new
1051 RNG object. This was done to allow this sort of use of the
1052 RNG in code that has no chance to allocate RNG object. All
1053 applications currently allocate this and many routines in the
1054 library use this. Affected file lib/silccrypt/silcrng.[ch].
1056 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1057 it to use the Global RNG API.
1059 * Defined Authentication Payload into protocol specification that
1060 is used during SILC session to authenticate entities. It is
1061 used for example by client to authenticate itself to the server
1062 to obtain server operator privileges.
1064 Implemented this payload into the lib/silccore/silcauth.[ch].
1065 Implemented also routines for public key based authentication
1066 as the new protocol specification dictates.
1068 Moved definitions of different authentication methods from
1069 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1071 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1072 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1073 silc_pkcs_verify_with_hash functions into the file
1074 lib/silccrypt/silcpkcs.[ch].
1076 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * The client entry's userinfo pointer must be always valid.
1079 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1080 will fail since it requires the userinfo. Now, the userinfo
1081 is allocated as "" if actual userinfo does not exist. Actually,
1082 it must exist and it is totally Ok to drop client connections
1083 that does not announce the userinfo. However, we will make
1084 this workaround for now.
1086 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1087 to return the remote port by socket.
1089 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1092 SILC_SERVER_PENDING_EXEC and added an new macro
1093 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1094 data or when error occurs while processing the pending command.
1096 Added new argument `destructor' into silc_server_command_pending
1097 and to the SilcServerCommandPending object. This destructor is
1098 now called after calling the pending callback or if error occurs
1099 immediately. If error occurs the actual pending callback won't
1100 be called at all - only the destructor. The destructor may be
1101 NULL if destructor is not needed.
1103 All this applies for client library code as well. Similar
1104 changes were made there as well for the pending commands.
1106 In the client, the application must now allocate the
1107 SilcClientCommandContext with the silc_client_command_alloc
1110 * Added reference counter to the SilcServerCommandContext. Added
1111 function silc_server_command_alloc and silc_server_command_dup
1114 Same type of functions added to the client library for the same
1117 * Removed the cmd_ident from IDListData away since it is now
1118 global for all connections. It is the command identifier used
1119 in command sending and with pending commands. The affected file
1122 * Added reference counter to the SilcSocketConnection objecet to
1123 indicate the usage count of the object. The object won't be
1124 freed untill the reference counter hits zero. Currently only
1125 server uses this, and client ignores it. The client must be
1126 set to use this too later. The affected files are
1127 lib/silccore/silcsockconn.[ch]. Added also the function
1128 silc_socket_dup to increase the reference counter.
1130 This was mainly added because it is possible that the socket
1131 is removed underneath of pending command or other async
1132 operation. Now it won't be free'd and proper DISCONNECTING
1133 flags, etc. can be set to avoid sending data to connection that
1134 is not valid anymore.
1136 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1137 the connection. After that it sets SILC_SET_DISCONNECTED.
1138 It is, however, possible that the socket data is not still freed.
1139 The silc_server_packet_process now checks that data is not
1140 read or written to connection that is DISCONNECTED. The socket
1141 get's freed when the reference counter hits zero.
1143 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Changed the client operation API: channel_message operation's
1146 `sender' is now the client entry of the sender, not the nickname
1147 and the `channel' is the channel entry, not the channel name.
1149 In the private_message operation the `sender' is now also the
1150 client entry of the sender not the nickname.
1152 Affected file is lib/silcclient/ops.h and all applications
1153 using the client operations.
1155 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Moved the calling of ops->connect() from connect_to_server_final
1158 into receive_new_id functin since that is the point when the
1159 client is actually allowed to send traffic to network. The
1160 affected file is lib/silcclient/client.c.
1162 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1165 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1166 (if needs broadcasting) instead of broadcasting the packets one
1167 by one which would make a burst in the network traffic.
1169 * Added `broadcast' argument to the functions in silcd/server.[ch]
1170 silc_server_create_new_channel[_with_id] to indicate whether
1171 to send New Channel packet to primary router.
1173 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Added new function into the silcd/server.[ch] files:
1176 silc_server_create_new_channel_with_id to create new channel with
1177 already existing Channel ID.
1179 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1180 lib/silccore/silcpacket.h. This packet is used t send list of
1181 Set Mode payloads inside one packet. Server uses this to set
1182 the modes for the channels and clients on those channels, that it
1183 announced to the router when it connected to it. The protocol
1184 specification has been updated accordingly.
1186 * The silc_server_new_channel did not handle the packet coming
1187 from normal server as it normally does not send that. However,
1188 when it announces its channels it does send it. Implemented
1189 the support for that.
1191 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1192 into the file lib/silccore/id.h.
1194 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Fixed memory leaks in the functions silc_idlist_del_client,
1197 silc_idlist_del_channel and silc_idlist_del_server in the file
1198 silcd/idlist.c. All of those leaked like a sieve.
1200 * Fixed some small memory leaks in the client's function
1201 silc_client_notify_by_server.
1203 * Added functions into silcd/server.c: silc_server_announce_clients,
1204 silc_server_announce_channels and silc_server_announce_server.
1205 These functions are used by normal and router server to announce
1206 to its primary router about clients, channels and servers (when
1207 router) that we own. This is done after we've connected to the
1210 These functions effectively implements the following packet types:
1211 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1212 and SILC_PACKET_NEW_ID_LIST.
1214 * Added new functions into the silcd/packet_receive.[ch]:
1215 silc_server_new_id_list, silc_server_new_channel_list and
1216 silc_server_new_channel_user_list to handle the incoming
1217 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1219 * Added support of changing Channel ID in the function
1220 silc_server_replace_id. If the server that announces a channel
1221 to the router already exists in the router (with same name but
1222 with different Channel ID), router is responsible to send
1223 Replace ID packet to the server and force the server to change
1224 the Channel ID to the one router has.
1226 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1227 client that the Channel ID has been changed by the router. The
1228 normal server sends this to the client. Client must start using
1229 the new Channel ID as the channel's ID.
1231 Implemented handling of this new type into lib/silcclient/client.c
1232 into the function silc_client_notify_by_server.
1234 * Added new function silc_idlist_replace_channel_id into the files
1235 silcd/idlist.[ch] to replace the Channel ID.
1237 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Call silc_server_command_identify_check always when processing
1240 the IDENTIFY command in silcd/command.c
1242 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1245 send keepalive packets. The packet can be sent by clients,
1246 servers and routers.
1248 Added function silc_socket_set_heartbeat into the file
1249 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1250 If not set, the heartbeat is not performed. The actual
1251 heartbeat is implemented in the low level socket connection
1252 library. However, application is responsible of actually
1255 Added silc_server_send_heartbeat to send the actual heartbeat
1256 packet into silcd/packet_send.[ch]. Server now performs
1257 keepalive with all connections.
1259 * Added silc_task_get_first function into lib/silcutil/silctask.c
1260 to return the timeout task with shortest timeout. There was a bug
1261 in task unregistration that caused problems. TODO has been
1262 updated to include that task system must be rewritten.
1264 * The client library will now resolve the client information when
1265 receiving JOIN notify from server for client that we know but
1266 have incomplete information.
1268 * Rewrote parts of silc_server_remove_from_channels and
1269 silc_server_remove_from_one_channel as they did not remove the
1270 channel in some circumstances even though they should've.
1272 * Encryption problem encountered in server:
1274 The LEAVE command used to send the Channel Key packet to the
1275 router immediately after generating it. However, the code
1276 had earlier sent Remove Channel user packet but not immediately,
1277 ie. it was put to queue. The order of packets in the router
1278 was that Channel Key packet was first and Remove Channel User
1279 packet was second, even though they were encrypted in the
1280 reverse order. For this reason, MAC check failed. Now, this
1281 is fixed by not sending the Channel Key packet immediately but
1282 putting it to queue. However, this is more fundamental problem:
1283 packets that are in queue should actually not be encrypted
1284 because packets that are sent immediately gets encrypted
1285 actually with wrong IV (and thus MAC check fails). So, packets
1286 that are in queue should be encrypted when they are sent to
1287 the wire and not when they put to the queue.
1289 However, the problem is that the current system has not been
1290 designed to work that way. Instead, the packet is encrypted
1291 as soon as possible and left to the queue. The queue is then
1292 just purged into wire. There won't be any fixes for this
1293 any time soon. So, the current semantic for packet sending
1296 o If you send packet to remote host and do not force the send
1297 (the packet will be in queue) then all subsequent packets to the
1298 same remote host must also be put to the queue. Only after the
1299 queue has been purged is it safe again to force the packet
1302 o If you send all packets immediately then it safe to send
1303 any of subsequent packets through the queue, however, after
1304 the first packet is put to queue then any subsequent packets
1305 must also be put to the queue.
1307 Follow these rules and everything works fine.
1309 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added new function silc_server_remove_clients_by_server to
1312 remove all client entries from ID list when the server connection
1313 is lost. In this case it is also important to invalidate all
1314 client entires as they hold the invalid server entry. This
1315 fixes fatal bug when server has lost connection and will reconnect
1318 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Made some sanity checks to silc_server_daemonise like to check
1321 whether the requested user and group actually exists.
1323 * Added sanity check to SKE's silc_ske_responder_finish to check
1324 that the public and private key actually is valid.
1326 * Invalidate the client's nickname when receiving Replace ID
1327 packet and the Client ID is being replaced. This means that the
1328 server will query the nickname if someone needs it (client)
1331 * Sort the ID Cache in client library when the ID Cache data
1332 has changed (needs sorting).
1334 * Do not allow for SILC client to create several connections to
1335 several servers. The client does not support windows right now
1336 and generating multiple connections causes weird behaviour.
1338 Irssi-silc client does support windows and can handle several
1339 connections without problems, see: www.irssi.org and SILC plugin.
1341 * Fixed some places where client was added to the IDList. The
1342 rule of thumb is following (in order to get everything right):
1343 If the client is directly connected local client then the
1344 `connection' argument must be set and `router' argument must be
1345 NULL to silc_idlist_add_client function. If the client is not
1346 directly connected client then the `router' argument must
1347 bet set and the `connection' argument must be NULL to the
1348 silc_idlist_add_client function.
1350 * The funtion silc_server_packet_send_local_channel actually did
1351 not check whether the client was locally connected or not. It
1352 does that now. Fixed a bug related to LEAVE command.
1354 * Fixed Remove Channel User payload parsing bug in server's
1355 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1357 * The server's silc_server_save_channel_key now checks also the
1358 global ID list for the channel as it might not be in the local
1359 list. Fixed a bug related to LEAVE command.
1361 * Is this the end of the [<unknown>] buglet that has been lurking
1362 around for a long time? A little for loop fix in server's
1363 silc_server_command_whois_parse that is used by both IDENTIFY
1364 and WHOIS command. At least, this was a clear bug and a cause
1365 of one type of [<unknown>] buglet.
1367 * WHOIS and IDENTIFY commands call the function
1368 silc_server_command_[whois/identify]_check function even if
1369 we are not router server.
1371 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Added --with-gmp configuration option. If set the GMP
1374 is always compiled in the SILC source tree. If not set then
1375 it is checked whether the system has the GMP3 installed. If
1376 it has then the GMP won't be compiled (the system's headers
1377 and library is used), if it doesn't have it then the GMP is
1378 compiled in the SILC source tree.
1380 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Changed RSA private exponent generation to what PKCS #1
1383 suggests. We try to find the smallest possible d by doing
1384 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1385 not security fix but optimization.
1387 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Added new config entry [Identity] to fork the server and run
1390 it as specific user and group. A patch from Bostik.
1392 * Imported Dotconf configuration library into lib/dotconf.
1393 This will be used to create the SILC configuration files later.
1394 It will appear in the distsribution after this commit.
1396 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * A big code auditing weekend happening. Auditing code for
1399 obvious mistakes, bugs and errors. Also, removing any code
1402 Removed files for being obsolete:
1404 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1405 inline in the file lib/silcutil/silcbuffer.h)
1407 o lib/silcutil/silcbufutil.c (the header has inline versions)
1409 Changed code to fix possible error conditions:
1411 o The buffer formatting routines now check that the destination
1412 buffer really has enough space to add the data. This applies for
1413 both buffer formatting and unformatting
1414 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1415 unformatting was changed to accomodate following rules:
1416 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1417 sent to the function while XXX_*STRING will not allocate or copy
1418 the data into the buffer. Instead it sets the pointer from the
1419 buffer into the pointer sent as argument (XXX_*STRING used to
1420 require that the pointer must be allocated already). This change
1421 makes this whole thing a bit more consistent and more optimized
1422 (note that the data returned in the unformatting with XXX_*STRING
1423 must not be freed now). The routines return now -1 on error.
1425 o Tried to find all code that use buffer_format and buffer_unformat
1426 and added return value checking to prevent formatting and
1427 especially unformatting errors and possible subsequent fatal
1430 o Changed ske->x and ske->KEY to mallocated pointers in
1431 lib/silcske/silcske.h. Fixed possible data and memory leak.
1433 o Added return value checking to all *_parse* functions. Fixed
1434 many memory leaks as well.
1436 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1437 so that buffer overflows would not happen. All code now also
1438 checks the return value as it can fail.
1440 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Added reconnection support to server if the normal server looses
1443 its connection to the router (for example if router is rebooted).
1444 The server performs normal reconnection strategy implemented
1445 to the server. Affected file silcd/server.c.
1447 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Added new packet type SILC_PACKET_SET_MODE that is used to
1450 distribute the information about changed modes (for clients,
1451 channels and clients channel modes) to all routers in the
1452 network. Updated the protocol specification accordingly.
1454 Added functions into silcd/packet_send.c and
1455 silcd/packet_receive.c: silc_server_send_set_mode,
1456 silc_server_set_mode.
1458 Added new files silcmode.[ch] into lib/silccore that implements
1459 the encoding and decoding of Set Mode Payload. Added new type
1460 SilcSetModePayload. Moved the definitions of different modes
1461 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1463 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Oops, a little mistake in server's connection authentication
1466 protocol. The protocol is not ended with FAILURE but with
1467 SUCCESS if the authentication is Ok. :) Affected file is
1470 * Implemented NICK_CHANGE notify handling in server in the file
1471 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1472 the local clients on the channel. After the changing nickname
1473 in router environment snhould work and the [<unknown>] nickname
1474 should appear no more.
1476 The silc_server_replace_id function that receives the Replace ID
1477 payload now sends the NICK_CHANGE notify type also in the file
1478 silcd/packet_receive.c
1480 * Changed WHOIS and IDENTIFY command to support the maximum amount
1481 of arguments defined in protocol specs (3328 arguments). This
1482 fixed a bug that caused problems when there were more than three
1485 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Added extra parameter, command identifier, to the
1488 silc_client_send_command so that explicit command identifier
1491 Changed that ID list routines uses specific command identifier
1492 when sending WHOIS/IDENTIFY requests to the server so that they
1493 can be identified when the reply comes back.
1495 Affected files lib/silcclient/command.[ch],
1496 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1498 * Added `sender' argument to silc_server_packet_send_to_channel
1499 to indicaet the sender who originally sent the packet to us
1500 that we are now re-sending. Ignored if NULL. Affected file
1501 silcd/packet_send.[ch].
1503 * Added some server statistics support in silcd/server_internal.h
1504 SilcServerStatistics structure and around the server code. Also
1505 send some nice statistics information when client is connecting
1508 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Fixed channel ID decoding in server's JOIN command reply in
1511 silcd/command_reply.c
1513 * Fixed braodcasting of replace ID payload to not to send it if
1514 we are standalone server in silcd/packet_receive.c.
1516 * Fixed all channel message sending routines to not to send
1517 packets to clients that has router set, since they are routed
1518 separately in the same function earlier. Affects file
1519 silcd/packet_send.c and all channel packet sending functions.
1521 * In USERS reply, res_argv[i] are not allocated, the table
1522 is allocated. Thus changed that free the table, not its
1525 * In server's whois_check and identify_check if the client is
1526 locally connected do not send any WHOIS commands - they are not
1529 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Fixed some minor bugs in client when sending WHOIS command. The
1532 arguments was in wrong order.
1534 * Removed statis function add_to_channel from server in
1535 silcd/command.c that was previously used with the joining but
1538 * Tested USERS command in router environment successfully with two
1539 routers, two servers and two clients.
1541 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Reorganized the USERS command and command reply in client library
1544 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1545 When the command is given by user we register a pending command
1546 callback that will reprocess the command after the reply has been
1547 received from the server. When reprocessing the packet we then
1548 display the information. Thus, the USERS information is displayed
1549 now in the command callback instead of in the command reply
1550 callback. The processing of the command is same as previously
1551 when server has sent the command reply in the JOINing process.
1553 * Added to USERS command in silcd/command_reply.c to join the client,
1554 we didn't use to know about, to the channel after we've created
1555 a client entry for it. Also, for clienet we did know already still
1556 check whether it is on the channel or not and add it if not.
1558 * Removed silc_server_command_join_notify as the function and its
1561 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Changed the client's pending command handling to the same as the
1564 server's pending command handling. It is also now possible to
1565 execute command reply functions from other command reply
1566 function as the function callbacks for commands and command
1567 replies are one and same. The pending commands are not static
1568 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1569 in client connection context. Thus, pending commands are server
1570 connection specific as it is convenient.
1572 Changed the function silc_client_command_pending and
1573 silc_client_command_pending_del and added new function
1574 silc_client_command_pending_check. Removed the
1575 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1578 * Added cmd_ident, current command identifier, to the client
1579 connection context in lib/silcclient/client.h to keep track on
1580 command identifiers used in command sending. Client's command reply
1581 function handling now supports the mandatory command identifiers.
1583 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1584 funtions in client to fully support pending command callbacks.
1586 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1587 as one of the arguments to the application in the command reply
1590 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1591 before first releasing SILC but came back. Now it is removed again
1592 and should come back nomore. The FORWARDED flag was used only
1593 by the JOINing procedure by forwarding the command packet to router.
1594 Now, the JOINing procedure has been changed to more generic (due
1595 to various router environment issues) and FORWARDED is not needed
1596 anymore for anything. The protocol specification is yet to be
1599 Now, removed silc_server_packet_forward from server and the flag
1600 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1602 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Renamed NAMES command to USERS command. The NAMES was named that
1605 due to historical reasons. Now it is renamed. Also, rewrote
1606 parts of the USERS command. The nickname list is not sent anymore
1607 by the server. Only Client ID and mode lists are sent in the USERS
1608 command. Changed this also to the protocol specification.
1610 The client now resolves the names and stuff after it receives
1611 the USERS list from the server when joining to the channel.
1613 * WHOIS and IDENTIFY commands has been changed to support multiple
1614 Client ID's per command. One can now search for multiple users
1615 in the network by sending only one WHOIS or IDENTIFY command.
1616 Changed the code and the protocol specifications.
1618 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1619 uses silc_server_command_whois_parse to parse the request. */
1621 * If normal server, do not parse the WHOIS and IDENTIFY requests
1622 before sending it to the router. Saves some time.
1624 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1626 * Fixed JOIN command on client library. Wrong number of arguments
1627 used to crash the client.
1629 * Added silc_server_channel_has_global function to check whether
1630 channel has global users or not.
1632 * Added silc_server_channel_has_local function to check whether channel
1633 has locally connected clients on the channel.
1635 * The silc_server_remove_from_one_channel now checks whether the
1636 channel has global users or not after given client was removed from
1637 the channel. It also checks whether the channel has local clients
1638 on the channel anymore. If it does not have then the channel entry
1639 is removed as it is not needed anymore.
1641 * The silc_server_notify now checks on JOIN notify whether the joining
1642 client is one of locally connected or global. If it is global then
1643 the channel has now global users on the channel and that is marked
1644 to the channel entry. Also, it now saves the global client to
1645 global list who is joining and JOINs it to the channel. This is
1646 for normal server, that is.
1648 Changed silc_server_send_notify_on_channel,
1649 silc_server_packet_relay_to_channel and
1650 silc_server_packet_send_to_channel check if we are normal server
1651 and client has router set (ie. global client) do not send the
1652 message to that client, as it is already routed to our router.
1654 * Implemented LEAVE notify type handling in silc_server_notify
1657 * Tested LEAVE command in router environment successfully. Tested
1658 with two routers, two servers and two clients.
1662 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1664 * Implemented SIGNOFF notify type handling in silc_server_notify
1667 * silc_server_remove_id now removes the client entry from all channels
1668 it has joined and thusly sends SIGNOFF notify type.
1670 * Rewrote the NAMES list generation in server by removing two excess
1671 loops. The lists are created now inside one loop.
1673 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * silc_server_remove_channel_user checks now also global list
1676 for channel and client.
1678 * silc_server_new_channel_user checks now both local and global
1679 list for channel and client. Fixed a bug in client id decoding.
1680 Used to decode wrong buffer.
1682 * silc_server_channel_message checks now both local and global
1683 list for channel entry.
1685 * Tested channel joining (hence JOIN) in router environment
1686 successfully. Tested with two routers, two servers and two
1689 * Tested channel message sending in router environment successfully.
1691 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Added silc_server_save_channel_key into server.[ch] to save the
1694 received channel key in Channel Key payload processing. It is
1695 also used in JOIN command reply handling.
1697 Equivalent function silc_client_save_channel_key added into
1698 client.[ch] into client library.
1700 * Changed JOIN command reply to send information whether the channel
1701 was created or not (is existing already) and the channel key
1702 payload. Changed protocol specs accordingly.
1704 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1705 the request was sent by ID and not by nickname. Crashed on
1708 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1711 now correctly save the received data.
1713 * silc_server_free_sock_user_data now notifies routers in the
1714 network about entities leaving the network.
1716 At the same time implemented functions silc_server_remove_id
1717 and silc_server_send_remove_id to receive and send REMOVE_ID
1718 packets. The packet is used to notify routers in the network
1719 about leaving entities. The ID removed will become invalid in
1722 * Added function silc_idlist_del_server into server. Removes and
1723 free's server entry from ID list.
1725 * silc_server_private_message function now checks, if we are router,
1726 that the destination ID really is valid ID, naturally.
1728 * In router when NEW_ID packet is received (for new client) the
1729 hash of the Client ID is saved in the ID Cache but the
1730 client->nickname is set to NULL, instead of putting the hash
1733 IDENTIFY command now also checks that client->nickname must be
1734 valid. If it is not if will request the data from the server who
1735 owns the client. Added new function
1736 silc_server_command_identify_check.
1738 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1739 to set the command to already allocated Command Payload.
1741 * Tested private message sending in router environment with two
1742 routers, two servers and two clients. Fixed minor bugs and now
1745 * Fixed segfault from client's NAMES command. Used to crash if
1748 * Forwarded packets must not be routed even if it is not destined
1749 to the receiver. Changed server code comply with this.
1751 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Added `require_reverse_mapping' boolean value to ServerParams
1754 structure. If TRUE (not default) the server will require that
1755 the connecting host has fully qualified domain name.
1757 If the reverse mapping is not required and hostname could not be
1758 found the IP address is used as hostname.
1760 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Implemented version string checking to both client and server.
1763 The check is incomplete currently due to the abnormal version
1764 strings used in development version of SILC.
1766 * Changed all command functions in server to use the new
1769 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Changed char *data to unsigned char *data in ID Cache system to
1772 support binary data as ID Cache data. Changed code to support
1773 binary data in lib/silccore/idcache.c.
1775 * Renamed silc_server_packet_relay_command_reply to
1776 silc_server_command_reply as it is normal packet receiving
1777 function. Rewrote the function to accept command replys for
1778 servers and not only for clients.
1780 * Mark remote router always as registered server if we are connecting
1781 to it. Otherwise, commands sent by the router to us are ignored.
1783 * All ID List find routines now returns the ID Cache Entry pointer
1784 as well if requested.
1786 * WHOIS command works now in router environment, tested with two
1787 routers, two servers and two clients.
1789 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1790 in router environment (as it is almost equivalent to WHOIS) but
1791 hasn't been tested thoroughly. Added new functions:
1793 silc_server_command_identify_parse
1794 silc_server_command_identify_send_reply
1795 silc_server_command_identify_from_client
1796 silc_server_command_identify_from_server
1798 * Disabled route cache adding because adding two different ID's with
1799 same IP replaces the old cache entry thus giving wrong route.
1800 The entry->router->connection is always the fastest route anyway
1801 so route cache may not be needed. Of course, new routes maybe
1802 established after receiving the ID when the entry->router->connection
1803 might not be anymore the most optimal.
1805 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Add route cache for received ID for fast routing.
1809 * Added silc_server_packet_route to route received packet on router
1810 that is not destined to us.
1812 * Renamed silc_server_get_route to silc_server_route_get.
1814 * Added id_string and id_string_len fields into SilcServer to
1815 include encoded ServerID for fast comparing without excess
1816 encoding of the ID's.
1818 * Cleaned up WHOIS command on server side. Added following static
1821 silc_server_command_whois_parse
1822 silc_server_command_whois_check
1823 silc_server_command_whois_send_reply
1824 silc_server_command_whois_from_client
1825 silc_server_command_whois_from_server
1827 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1828 arguments in command replies. All command functions should be
1829 updated to use this macro.
1831 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Minor typo fixes on command reply handling on server.
1835 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Added silc_server_command_add_to_channel internal routine to add
1838 the client to the channel after router has created the channel and
1839 sent command reply to the server.
1841 * Added generic silc_server_send_command to send any command from
1844 * Use static buffer with ID rendering instead of duplicating data.
1846 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Fixed a channel user mode bug when joining to a channel server gave
1849 everybody channel founder rights, oops.
1851 * We mark ourselves as the router of the incoming server connection
1852 if we are router ourselves. This way we can check in some packet
1853 sending functions whether it is locally connected server. For
1854 incoming router connections we put NULL.
1856 * For router sending packets locally means now always sending the
1857 packet cell wide; to local clients and local servers. For normal
1858 server sending packet locally means sending it to only local
1861 * Fixed the JOIN command to really work in router environment. If the
1862 channel is created it is always created by the router. Router is
1863 also responsible of making the initial joining to the channel,
1864 sending JOIN notify to the sending server and distributing
1865 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1866 does not exist server doesn't do anything else but forward the
1867 command to the router which performs everything.
1869 * Added silc_server_send_channel_key function to send the Channel Key
1872 * Added silc_server_create_channel_key to create new channel key. The
1873 channel key is now re-generated everytime someone joins or leaves
1874 a channel, as protocol dictates. Note: channel->key_len is the
1877 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1880 packet_receive.[ch] to separate packet sending and receiving
1881 routines. The server.[ch] now includes everything else including
1882 actual packet processing (writing and reading data) and other
1885 Renamed silc_server_private_message_send_internal to
1886 silc_server_send_private_message. The routine is still though
1887 used only to relay private messages as server does not send
1888 private messages itself.
1890 Renamed silc_server_new_channel to silc_server_create_new_channel
1891 and added new function sicl_server_new_channel that handles the
1892 incoming New Channel packet. Added also new sending function
1893 silc_server_send_new_channel to send New Channel Payload.
1895 * Added new function silc_server_notify to process incoming notify
1896 packet to the server/router. Server may then relay the notify
1897 to clients if needed.
1899 * Added new function silc_server_new_channel_user to process incoming
1900 New Channel User packet. Router will redistribute the packet and
1901 send JOIN notify to its local clients and locally connected servers
1902 if needed. Normal server will send JOIN notify to its local client
1903 on same channel when received this packet. Added also corresponding
1904 sending function silc_server_send_new_channel_user to sent the
1907 * Added boolean route argument to send_notif_to_channel and
1908 packet_send_to_channel functions to attempt to route the packet
1909 if it is TRUE and send only locally if it is FALSE.
1911 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * silc_server_replace_id now broadcasts the received replace ID
1914 packet if it is not broadcast packet already. The router must
1915 broadcast to inform other routers about changed ID.
1917 * Added backpointer to server's router into SilcServer context in
1918 silcd/server_internal.h.
1920 * Fixed silc_server_packet_broadcast to send correct broadcast
1923 * The channel key is now distributed to the local client as soon
1924 as it is received from the router (in router environment) so that
1925 no other packet may be sent for the channel until client has
1928 * silc_server_remove_channel_user now broadcasts the received
1929 Remove Channel User packet if it is not broadcast packet already.
1930 The router must broadcast to inform other routers about removed
1933 * Added users field into SilcPacketContext that is a reference count
1934 of the context. One can increase the reference count by calling
1935 silc_packet_context_dup which is now changed to just increase the
1936 reference count instead of duplicating the data. The reference
1937 count is decresed by calling silc_packet_context_free that will
1938 free the data after the reference count hits zero.
1940 For now on the packet context and everything allocated into it
1941 (including the raw packet from network) must be freed by calling
1942 the new silc_packet_context_free function. Added also new function
1943 silc_packet_context_alloc that must be used now to allocate the
1944 context. This also means that if a routine is asynchronous from
1945 silc_[client/server]_packet_parse_type the packet context must
1946 be duplicated by calling silc_packet_context_dup. Otherwise it
1947 gets free'd after silc_[client/server]_packet_parse_type returns.
1948 Also, one must remember that if packet is duplicated then its
1949 reference count must be decresed by calling the free function as
1950 many times as it was duplicated.
1952 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1953 from both client and server.
1955 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Made joining to a channel working in router environment.
1959 * Cleaned up JOIN command on server side and create function
1960 silc_server_command_join_channel internal routine to make the
1963 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1965 * Changed silc_command_pending list to SilcDList. Also, added
1966 `ident' field to SilcServerCommandPending structure to identify
1967 the reply and to call correct callback.
1969 Added silc_server_command_pending_check function to replace the
1970 corresnponding macro. The silc_command_pending list is not
1973 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1974 to set identifier to previously allocated Command Payload. It
1975 is used to set identifier for command when resending Command
1978 * Added silc_command_payload_encode_payload to encode Command
1979 Payload buffer from SilcCommandPayload structure.
1981 * Added silc_argument_payload_encode_payload to encode Argument
1982 payload buffer from SilcArgumentPayload structure.
1984 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Changed WHOIS command to support router connection on server side.
1987 The whois request is always sent to router unless the server is
1988 standalone server. After server has received the reply from the
1989 router will it send the reply to the client.
1991 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1992 broadcast received broadcast packet. The function is used only
1993 by router. The broadcast packet is always sent to the router's
1996 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1997 render given ID to printable string, for log files for example.
1999 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Made basic router to router connections working. At least they
2002 can now connect to each other but nothing really works the way
2003 they are supposed - yet.
2005 * Added new initiator token to RouterConnection configuration
2006 file in silcd/serverconfig.[ch]. It is used to tell whether we
2007 are the initiator to the remote router or whether we'll expect
2008 the other end to connect.
2010 * Moved registering of listener task to silc_server_init, hence
2011 the server starts listenning as soon as it is run, even if it
2012 does not have connections to other routers. Let's see how well
2015 * Changed default connection retry timeouts for more suitable in
2018 * Removed cipher and such arguments from silc_idlist_add_client
2019 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2020 Added new function silc_idlist_add_data to add the keys and stuff
2023 * Added SilcIDListData structure and added it to SilcClientEntry
2024 and SilcServerEntry as their first field in the structure. This
2025 way we can explicitly cast the ID entries to the SilcIDListData
2026 structure and get common data for the entries. In past, we had
2027 to first check what type of connection it is and then cast it to
2028 correct ID entry type. Now, we can directly cast the opaque
2029 pointer to the SilcIDListData (no matter what ID entry it actually
2030 is) and get the data needed.
2032 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2035 in some circumstances even if threre were timeout tasks, though not
2036 IO tasks, but tasks anyway. Now fixed.
2038 * Defined SilcServerConnection structure to hold connection specific
2039 stuff about directly connected servers and routers. The definition
2040 is currently in silcd/server_internal.h. I thought about having
2041 a bit more important role fro this struct but for now it is used
2042 only when connecting to other server (or router actually).
2044 * Added connecting retry support in server when connecting to
2045 router(s). The retry feature implement exponential backoff
2046 algorithm. Also, added SilcServerParams structure to hold default
2047 parameters for server. For now, it include these retry settings
2048 and are hard coded. After server is moded to be as Silc Server
2049 Library this structure will be more important.
2051 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2053 * Changed client librarys channel->clients table to SilcList and
2054 changed code accordingly.
2056 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Changed client's channel table to SilcList and changed code
2059 accordingly. Also changed SilcChannelClientEntry to include back-
2060 pointer to the channel so that client entry can use that structure
2061 as list as well and we have fast cross-reference to the channel.
2062 This change dramatically decreased the complexity of channel
2063 handling with client entry and vice versa (removed one extra
2064 loop when searching for channel entry from many functions).
2066 * Changed server->sim from table to SilcDList and changed code
2069 * NAMES command can now be used from user interface. It will show
2070 the user list on the channel, neatly.
2072 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2073 Code now saves realname of the user if it becomes available.
2075 * Renamed configure.in to configure.in.pre and made ./prepare
2076 script to automatically add correct version string to
2077 configure.in which it creates from configure.in.pre.
2079 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * NAMES command reply now shows users mode with the nickname when
2084 * Moved silc_client_ch[u]mode[_char] functions from
2085 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2086 place sucks, they are utility functions and should be in some
2089 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2091 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2094 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Added TRQ (efficient deque and list library) into lib/trq. This is
2099 a very good list library that is currently used in the SILC. Defined
2100 SilcList API over the library because I didn't like the API very
2101 much. See lib/trq/silclist.h for the API and examples of how to
2102 use the API. Fixed various places in the code to use the new
2103 SilcList API. The SilcList is meant for lists that has a structure
2104 already defined as a list. It is not suitable to add just some
2105 context to the list (in TRQ, the context is the list actually).
2107 So, I defined SilcDList that can be used for the purpose where
2108 predefined list structure does not exit. This can be used as
2109 such list. Now some context just can be added to the SilcDList.
2110 Currently this list is not used in the SILC just yet, though there
2111 are a lot places where this can replace dynamically allocated
2112 tables and I will fix these places, later, to use SilcDList.
2113 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2114 and use TRQ internally).
2116 Also fixed some annoying warning messages that the original TRQ
2117 code generated. Also minor changes to TRQ's Makefile.in.
2119 * Added support for querying by Client ID to both WHOIS and
2120 IDENTIFY commands into server, as required by the protocol.
2122 * Removed method function pointers from SilcBuffer structure. They
2123 weren't used to anything and just increased the context size for
2124 no good reason. This change also made silc_buffer_alloc and
2125 silc_buffer_free functions inline functions.
2127 * Disabled command flooding detection support until it's fixed so
2128 that it accepts commands in but does not execute them more than once
2131 * Added silc_net_localhost(), to return local hostname, into
2132 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2133 that must be initialized before calling silc_client_init.
2135 * Added new function: silc_server_send_notify_on_channels to send
2136 notify messages to all channels client has joined. It is assured
2137 that the message is sent only once per client.
2139 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2140 lib/silcutil/silcutil.[ch] as silc_format function. The new
2141 function is generic and is used by server as well, not only by
2142 the logging routines.
2144 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2145 the provided version string was not acceptable. Added new function:
2146 silc_ske_check_version into lib/silcske/silcske.h. The function
2147 must be implemented by the application (client or server) and it
2148 does not reside in the SKE library. The function checks the version
2149 string remote end sent.
2151 * Added back pointers (to opaque context and to SilcSocketConnection)
2152 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2154 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2155 duplicate packet context structure.
2157 * Changed `notify' client operation to send same arguments as client
2158 receives from server except for ID's. ID's are mapped to correct
2159 ID entry and that is returned. Also, if channel entry is not sent
2160 by server but the notify is for channel the channel entry is sent
2161 to application (otherwise application doesn't know that it is for
2162 channel (library gets it from packet's Destination ID)).
2164 * Added silc_client_remove_from_channels into client library to
2165 remove a client from all channels it has joined to. Used when
2166 received SIGNOFF notify from server. Added also new function
2167 silc_client_replace_from_channels to replace old ID entry with
2168 new ID entry on all channels. Used when received NICK_CHANGE
2171 * Fixed ID Cache list handling in silc_idlist_get_client in
2172 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2173 to get (or query) client by ID.
2175 * Updated TODO list.
2177 * Added connection authentication status message defined by the
2178 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2179 support for these into the code in client and server side.
2181 * Added generic function silc_client_send_command to send any command
2182 with variable argument list. Application should use this function
2183 to send commands if the command functions provided by the library
2184 does not suite for the application's user interface needs.
2186 * Added new `failure' client operation. Application is notified about
2187 received failure packet if client is executing a protocol. In this
2188 case the protocol's execution has failed.
2190 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2191 is required by the protocol.
2193 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2194 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2197 * Added status flag to SilcSKE object to indicate realtime status
2198 of the SKE protocol.
2200 * Application receives now exactly same command reply arguments as
2201 the library receives from server. However, if ID is received the
2202 corresponding ID entry is returned to the application (eg. Client
2203 ID is mapped to correct SilcClientEntry entry and that is returned).
2204 Changed command_reply client operation due to this change.
2206 * Changed all ID's in commands and in command replys as ID Payloads.
2207 Change affected both client and server side codes.
2209 All ID's sent in SILC network (with execption of ID's in SILC
2210 Packet header) are sent in ID Payload to support variable length
2213 * Server now notifies nick changes and notifies all clients on
2214 the channels about the new nickname (about the new Client ID,
2217 * Implemented CMODE command to change channel modes. Supports all
2218 channel modes defined by the protocol specs except ban and invite
2219 lists. (Also, private channel key mode is supported but support for
2220 setting private channel key in client is missing, thus, this mode
2221 has no effect on client side (except that server requires that the
2222 client uses private channel key and normal channel traffic does not
2225 Also, invite mode works per se, but INVITE command does not work
2226 yet correctly, so you can set channel as invite only channel but
2227 inviting clients to the channel does not work (it is yet to be
2228 thought what's the best way to do it).
2230 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2231 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2232 Implemented CUMODE command to change user's mode on the channel.
2233 Supports all modes defined by the protocol specs.
2235 * Added NAMES command reply to return users modes on the channel.
2237 * Removed unnecessary and slow ciphers from lib/silccrypt.
2239 * Set SO_KEEPALIVE option to connection sockets by default.
2241 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2243 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2244 redefined the Notify Payload into protocol specs.
2246 * Added silc_id_payload_parse_id to get ID directly from raw
2249 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2252 accept searching by Client ID as well.
2254 * Added support for LEAVE and SIGNOFF notify types in client library.
2256 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2257 to parse ID Payload from raw data.
2259 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added flags parameter into silc_ske_assemble_security_properties
2262 function in lib/silcske/silcske.[ch].
2264 * Changed notify client operation to fit better for notify messages
2265 sent by server. The notify payload received from server is now
2266 passed to the application (after parsing it to SilcNotifyPayload).
2267 It is application's responsibility to retrieve the arguments
2268 from the payload and show the message the way it wants. The message
2269 sent by server is implementation specific.
2271 * Changed public keys to comply with the protocol specification.
2272 Old public keys are not supported anymore and are not compatible.
2274 * Removed nickname from Channel Payload as the latest draft removed
2275 it. The client must resolve the nickname from the NAMES command
2276 reply received when it joined the channel.
2278 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2280 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Fixed some errors in protocol specification drafts.
2284 * Created lib/silccore/silcnotify.c to implement Notify Payload
2285 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2286 generic payloads described by protocol specifications. The file
2287 includes implementations for ID Payload and Argument Payload.
2289 * Changed Command Payload implementation to use the new Argument
2290 Payload. Changed command_xxxx_payload to command_payload_xxxx
2291 to comply with SILC coding conventions.
2293 * Added suppport for Argument Payload handling in Notify Payload
2294 implementation as protocol requires it. Added the new support
2295 into server and client lib as well.
2297 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Added support for multiple nicknames on same channel. [n] is
2300 added locally to the nickname if there are more than one same
2301 nicknames on the channel.
2303 * Server now sends all nicknames that matched WHOIS request.
2304 Client also shows the list received from server.
2306 * Added TOPIC command to client side. User can now set and show
2307 current topic on channel.
2309 * Added MOTD command to client and server. Also, server sends the
2310 motd when client connects to the server.
2312 * Changed version strings to comply ISO 8601.
2314 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Fixed protocol error handling in client library. It should now
2317 cope even if the SKE fails for some reason.
2319 * Made new protocol specification drafts for submitting to IETF.
2321 * Implemented TOPIC command to server in silcd/command.c.
2323 * Added two new notify types into lib/silccore/silcnotify.h:
2324 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2325 notify nickname change and topic setting/change on a channel.
2327 * API change of command_reply operation in client library. The
2328 application gets now the status type received from server as well.
2330 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2334 * Cras fixed and optimized the packet handling even further and
2335 it should work now. Minor change to the prototype of function
2336 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2338 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added new function into lib/silcutil/silcschedule.[ch]:
2341 silc_schedule_with_fd to select() a specified fd. The function
2342 returns after timeout expires or data arrives or goes. The
2343 function is used by packet routines to wait that all data is
2344 received from network.
2346 * Fixed data reading from network in lib/silccore/silcpacket.c.
2347 The code now assures that all data is read from the fd and then
2348 continues packet processing. This was a bug fix since the code
2349 used to drop some data in some circumstances.
2351 * Added new function into lib/silcclient/client.[ch]:
2352 silc_client_start_key_exchange to start key exchange after
2353 connection has been established to server. The code internally
2354 now uses this funtion but its main purpose was to provide it
2355 for applications that perform their own connecting. After
2356 application has created a connection it merely calls this
2357 function to start the key exchange between client and server.
2358 The library takes care of everything else after that.
2360 Updated also lib/silcclient/README to explain the usage of
2363 * Do not send to application information that connection has
2364 been established. Application gets notified it by connect
2367 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Applied cras's patch to add silc_schedule_one function. The
2370 function runs scheduler once and returns.
2372 * Fixed the scheduler after cras messed it up. The timeout
2373 handling works now as it's supposed to work.
2375 * Added into lib/silccore/ silcnotify.h to include notify
2376 message types support. Changed silc_server_send_notify*
2377 functions, in server.[ch], to support those new notify types.
2378 Added the support for the notify types into client library,
2379 as well. Added new notify client operation into ops.h in
2382 * Changed silc_server_packet_send_to_channel to send normal
2383 packets instead of just channel message packets. The function
2384 is now used to send the notify packets to channels. It is not
2385 used to send channel message packets anymore, as server never
2388 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2389 va_arg()s as it seems to require it nowadays. I guess, if SILC
2390 is compiled with older va_arg() the new code should work anyway.
2392 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Splitted core library. Core library (lib/silccore) includes
2395 now only SILC protocol specific core (and common) components.
2396 Created new utility library (lib/silcutil) that includes more
2397 generic purpose stuff. The stuff for util library was taken
2398 from the old core library. This was minor and easy split.
2400 * Created SILC Client Library (lib/silcclient) that includes
2401 implementation of the SILC client without user interface. This
2402 was major move from silc/ directory. The code has been changed
2403 so that it is transparent towards the user interface. The
2404 silc/ directory includes now the same user interface as before
2405 and it uses the new client library. Read lib/silcclient/README.
2406 Basicly, the client library performs everything else related
2407 to SILC except user interface handling. Also, configuration
2408 files are considered to be part of user interface and library
2409 does not handle them.
2411 This change also changed a lot of structures, function naming etc.
2412 Most important change was that SilcClientWindow object was
2413 renamed to SilcClientConnection in the client library. Created
2414 also new file lib/silcclient/ops.h. Also added new files
2415 silc/local_command.[ch] and silc/client_ops.[ch].
2417 All these changes were made to make it easier for user interface
2418 designers to create what ever user interface for the SILC client
2421 It is also expected that the server will be moved to lib
2422 directory as well and SILC Server Library will be created;
2423 sometimes in the future.
2425 * Removed Local commands from lib/silccore/silccommand.h as
2426 they are application specific and new client library does not
2427 handle any of those anymore.
2429 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2430 old client implementation in silc/.
2432 * Added support for callback functions in SILC_LOG_* macros.
2433 Application can now set its own callbacks that will be called
2434 instead of using the default functions that will always print
2435 the debug messages to stderr (or stdout). Also, debugging can
2436 now be disabled by setting silc_debug to FALSE and re-enabled by
2437 setting it to TRUE. Note, that logging will still work even
2438 if debugging is disabled.
2440 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2441 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2442 silc_log_reset_debug_callbacks.
2444 * To enable debugging in silc client one must give now -d
2445 option on command line.
2447 * Changed silc_schedule_init to automatically allocate task queues
2448 if they are not allocated before calling it.
2450 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Added GMP 3.1 into math library.
2454 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2457 a channel in SILC network. The packet is used by servers and
2458 routers to notify other routers that user has left a channel.
2459 This little feature was missing until now. Added the feature
2460 to protocol specification as well.
2462 Added functions: silc_server_send_remove_channel_user and
2463 silc_server_remove_channel_user into server.[ch].
2465 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2466 lib/silccore/silcpacket.h. However, they are not implemented
2469 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2471 * Fixed joining to a channel and sending channel messages
2472 between server and router. The channel message sending should
2473 now work inside a cell.
2475 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Fixed the private message sending between server and router.
2478 The private message sending should now work inside a cell.
2480 * Added silc_server_replace_id into server.[ch] to replace
2481 existing ID in the SILC network.
2483 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2484 and silc_idlist_replace_server_id into idlist.[ch] in server.
2486 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Fixed the server to server connections. Server can again now
2489 connect to router. Router to router connections probably does
2492 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Added dynamic protocol registering support. Now protocols can
2495 registered and unregistered on the fly. Patch by cras.
2497 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Added lib/contrib directory to hold routines that some platforms
2500 don't have but are needed by SILC.
2502 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2503 into lin/contrib to provide getopt() and getopt_long() for
2504 those who don't have it.
2506 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Added AWAY command to client. When away message is set and
2509 client receives a private message packet the client automatically
2510 replies to the sender with the away message.
2512 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2513 bug seemed to be the cause of recent problems when compiling
2516 * Added version detection support to SKE protocol specification
2517 and added the new changes to the SKE implementation as well.
2518 There were other minor changes in the SKE protocol as well.
2520 Many changes in lib/silcske/silcske.[ch] and in
2521 lib/silcske/payload.[ch].
2523 * Added ^U functionality, clear input line. Patch from cras.
2525 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Mainly small bugfixes on core library. Fixed some debugging
2528 logging and buffer overflow in silclog.c.
2530 * Updated config.sub and config.guess on the distribution tree.
2532 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Added command lagging support in server. Client may execute
2535 commands now only once in two seconds.
2537 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Optimized packet reception. MAC computation and checking is now
2540 also more optimized. A lot previously duplicated code is now
2541 used as generic by both client and server.
2543 * Fixed key pair generation in clientutil.c
2545 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Added into lib/silccore/silcbufutil.[ch] new function;
2548 silc_buffer_realloc.
2550 * Moved generic packet sending/encryption functions to
2551 lib/silccore/silcpacket.[ch] from client and server. Some
2552 rewriting of the functions.
2554 * Moved all generic packet reception/decryption functions to
2555 lib/silccore/silcpacket.[ch] from client and server. The
2556 packet processing is now much cleaner in both client and server.
2557 These were major changes in both client and server.
2559 * Created many common functions in server to do packet sending.
2560 Previously code were duplicated a lot, this has been removed
2563 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Rewrote major parts of the ID cache system. Don't know
2566 whether it is better now or not but at least the API is more
2569 * Major rewrite on ID cache stuff on client because of the ID
2570 cache API changes. Added idlist.c to client.
2572 * Also major rewrite on ID cache stuff on server as well.
2573 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2574 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2575 in hand, instead they are all put into the ID cache system now.
2576 All server_idlist_* routines uses ID cache now instead of
2577 traversing its own lists (those lists does not exist anymore).
2578 SilcIDList though still exists. Also, SilcXXXEntry's are
2581 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Finally made the SKE implementation compliant to the protocol
2584 specification. All mp integers are now binary encoded as
2585 opposed being HEX encoded.
2587 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2590 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2591 functions: silc_[encode/decode]_pem. Also added function
2592 silc_encode_pem_file to PEM encode with newlines ('\n') for
2595 * SILC public keys are now encoded either PEM or binary. Same
2596 option is for private keys as well. By default private keys
2597 are binary encoded and public keys PEM encoded. Silly HEX
2598 encoding were removed.
2600 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2601 function to create fingerprints.
2603 * Fixed a bug in SHA1; does not change the original data anymore.
2605 * Partly implemented INFO command on client and server side.
2606 Fixed CLEAR command. Changes to SERVER command; show current
2607 server(s) when giving command without arguments. Added
2608 VERSION command to client.
2610 * Added check to server that unregistered connections cannot
2611 execute commands (unless it is specificly allowed).
2613 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Fixed screen refresh.
2617 * Fixed channel joining bug from client. On some circumstances
2618 client tried to join to a channel it had already joined.
2620 * Added public key verification process into client's protocol.c.
2621 The client now verifies the public key from user and saves
2622 it into ~./silc/serverkeys/ directory.
2624 Added into: clientutil.[ch]: silc_client_verify_server_key.
2626 * Changed SKE protocol's silc_ske_initiator_finish function
2627 to accept callback function that verifies the received public
2628 key. Removed old silc_ske_verify_public_key function.
2630 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2633 silc_pkcs_private_key[_data]_set.
2635 * Made the password and public authentication more cleaner in
2636 server's protocol.c.
2638 * Removed historic and obsolete protocol `channel_auth' from
2639 both client and server.
2641 * Removed wrong way of sending command status messages from
2642 server to client in server's command.c. The old way violated
2643 protocol specification.
2645 Changes to silccore/silccommand.[ch]: removed
2646 silc_command_encode_status_payload -> not needed anymore,
2647 changed silc_command_encode_payload_va to accept extra
2648 argument on variable argument list. The argument type must
2649 now be provided to the function. Also, added new function:
2650 silc_command_encode_reply_payload_va which is same as
2651 normal command_encode_payload_va except command status type
2652 is provided as extra argument.
2654 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Added ~./silc directory handling. The directory includes the
2657 public and private keys for the client.
2659 Added silc_client_check_silc_dir, silc_client_create_identifier
2660 and silc_client_load_keys.
2662 * Implemented SILC protocol compliant public key. Added public
2663 and private key saving to and loading from files.
2665 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2666 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2667 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2668 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2669 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2671 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2672 silc_pkcs_load_[public/private]_key.
2674 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Added silc_server_get_route (route.[ch]) to get connection
2677 data for the fastest route for given ID.
2679 * Implemented INVITE command on client and server. The command
2680 were re-defined in the SILC Protocol Specification and the
2681 implementation now complies with the specification.
2683 * Implemented PING command on client and server.
2685 * Implemented NAMES command on client and server. The server side
2686 supports currently only normal server not router server yet.
2687 Some changes to NAMES definition in SILC protocol specification.
2689 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Implemented LEAVE command on client and server.
2693 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2694 again. This change was made to the protocol as well. Server
2695 should not violate the protocol specification anymore.
2697 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2700 was tested. SOCKS4 was not but should work anyway.
