4 notify between routers.
6 * Implemented the INVITE command correctly to the server.
8 * Implemented the INVITE notify type handling in the server.
10 * Implemented the INVITE command to the client library and on the
13 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Added function silc_server_get_client_resolve to find the
16 client entry by ID from all ID lists and then resolve it
17 (using WHOIS) if it cannot be found. Affected file is
20 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
22 * Implemented the BAN command to the client library.
24 * The JOIN command in the server now checks the invite list
27 * Changed the silc_command_reply_payload_encode_va and the
28 silc_command_payload_encode_va to support that if argument is
29 NULL it ignores and checks the next argument. Affected file
30 lib/silccore/silccommand.c.
32 * Added silc_server_send_notify_ban to send the BAN notify
35 * Chaned the silc_notify_payload_encode to support that if
36 argument is NULL it ignores and checks the next argument.
37 Affected file lib/silccore/silcnotify.c.
39 * Tested ban lists in router environment successfully.
41 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
43 * Implemented BAN command to the server, in silcd/command.[ch].
45 * Removed the BAN and INVITE_LIST modes from the CMODE command
48 * Added function silc_string_match to regex match two strings.
49 Affected files lib/silcutil/silcutil.[ch].
51 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
53 * Redefined parts of the SilcChannelEntry in the server to support
54 the new ban and invite lists.
56 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
58 * Redefined the INVITE command. The same command can be used to
59 invite individuals to the channel but also to manage the invite
60 list of the channel (to add to and remove from the invite list).
61 Updated the protocol specs.
63 * Added new command SILC_COMMAND_BAN that can be used to manage
64 the ban list of the channel. Updated the protocol specs.
66 * Removed the channel modes: the SILC_CMODE_BAN and the
67 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
68 in the CMODE command. The equivalent features are now available
69 using INVITE and BAN commands. Updated the protocol specs.
71 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
72 in the network about change in the current ban list. The notify
73 type is not used by the client.
75 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
76 support the invite lists.
78 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Added new function silc_string_regexify that converts string
81 including wildcard characters into regex string that can
82 be used by the GNU regex library. Added into the file
83 lib/silcutil/silcutil.[ch].
85 Added silc_string_regex_combine to combine to regex strings
86 into one so that they can be used as one regex string by
87 the GNU regex library. Added into the file
88 lib/silcutil/silcutil.[ch].
90 Added silc_string_regex_match to match two strings. It returns
91 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
93 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Imported GNU regex to the soruce tree into lib/contrib.
96 Fixed some compiler warning from the regex.c.
98 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
100 * Fixed MOTD command in the server to work in router environment.
102 * Fixed the MOTD command in the client library to support
103 the server argument in the command.
105 * Added `nickname_len' argument to the silc_idlist_add_client
106 in the server, as the `nickname' argument may be binary data
109 * Added silc_idlist_get_channels to return all channels from
112 * Implemented LIST command to the server. Affected file is
115 * Implemented the LIST command to the client library and on the
118 * Added [<user count>] argument to the LIST command reply.
119 With private channels the user count is not shown.
121 * Updated TODO and README.
123 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
125 * The client entry's data.registered must be TRUE even with
126 global client entry on global client list. The data.registered
127 is used to check whether the client is anymore in the network,
128 for example with WHOWAS command so it must be valid.
130 * Fixed the WHOWAS command in the server. It now actually works
131 in router environment. Added function into silcd/command_reply.c
132 silc_server_command_reply_whowas_save.
134 * Added silc_idlist_purge function to the silcd/idlist.c
135 to periodically purge the ID Cache.
137 * Fixed INFO command in the server. It works now in router
138 environment. Added <server name> argument to the INFO command
139 reply. Updated the protocol specs.
141 * Fixed minor bug in silc_idcache_purge to not purge if the
142 expire value is zero.
144 * Fixed various bugs in WHOIS and IDENTIFY command handling as
145 they were buggy because of the WHOWAS information.
147 * Fixed local command MSG to handle the async resolving of
148 the remote client properly. It used to fail the first MSG.
149 Affected file silc/local_command.c.
151 * Added `data_len' field to SilcIDCache context.
153 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
155 * Update TODO. Todo in commands in the server.
157 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
160 used by routers as broadcast packet to inform other routers
161 about the changed user mode.
163 Implemented the notify handling in the server. Affected file is
164 silcd/packet_receive.c. Added the function
165 silc_server_send_notify_umode to the silcd/packet_send.[ch].
167 * Added new generic Channel Payload and deprecated the New Channel
168 Payload. The New Channel Payload is now the generic Channel
171 * Added new argument `mode' to the silc_server_send_new_channel
172 as it is required in the Channel Payload now.
174 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
175 and created a new and real SilChannelPayload to represent the
176 new generic Channel Payload. Implemented the encode/decode
177 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
179 * Added silc_server_get_client_channel_list to return the list
180 of channels the client has joined for WHOIS command reply.
181 Affected file silcd/server.[ch].
183 * Implemented the channel list sending in the WHOIS command reply
184 in server and in the client.
186 Implemented the channel list displaying on the user interface
187 as well. Affected file silc/client_ops.c.
189 * Added silc_channel_payload_parse_list to parse list of Channel
190 Payloads. It returns SilcDList list of SilcChannelPayloads.
191 Client for example can use this function to parse the list of
192 channels it receives in the WHOIS command reply. The caller
193 must free the list by calling silc_channel_payload_list_free.
194 Affected files lib/silccore/silcchannel.[ch].
196 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Added one new argument <user mode> to the WHOIS command reply
199 to return the mode of the user in SILC. Updated the protocol
202 Implemented it to the server and client.
204 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Fixed the mode printing on the user interface on joining.
207 Affected file silc/client_ops.c.
209 * Implemented the UMODE command and user modes in general to the
210 client library and to the user interface.
212 * Implemented the UMODE command to the server.
214 * The server now sends UNKNOWN_COMMAND error status if client sends
215 unknown command. Affected file silcd/command.c.
217 * All server commands now handle the command identifier the right
218 way when sending the command reply to the client. The client can
219 use to identify the command replies with the identifier.
221 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Added silc_server_get_client_route to resolve the route to
224 the client indicated by the client ID. Affected file is
227 * Added silc_server_relay_packet as general function to relay
228 packet to arbitrary destination. This deprecates functions
229 like _send_private_message_key, _relay_notify etc. Affected
230 file is silcd/packet_send.[ch].
232 Removed silc_server_send_key_agreement,
233 silc_server_send_private_message_key and
234 silc_server_packet_relay_notify functions from the file
235 silcd/packet_send.[ch].
239 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
240 server. Affected file silcd/packet_receive.[ch].
242 * Implemented the KILL command to the client. Implemented the
243 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
244 Affected files lib/silcclient/command[_reply].c and
245 lib/silcclient/client_notify.c. Implemented the KILL notify
246 printing in the user inteface.
248 * Fixed a lot silc_parse_nick memory leaks from the client
249 library in the file lib/silcclient/command.c.
251 * Changed the silc_server_send_notify_on_channels's `sender'
252 argument from SilcSocketConnection to SilcClientEntry to
253 check the sender as entry and not as connection object and not
254 to send to the client provided as argument. The affected file
255 is silcd/packet_send.[ch].
257 * The notify packets that are destined directly to the client used
258 to not to be processed by the server. Now changed that and the
259 server processes all notify packets. After relaying the packet
260 to the client the notify packet is processed in the server.
262 * The silc_server_free_client_data now checks whether there is
263 pending outgoing traffic for the client and purges the data to
264 the network before removing the client entry.
266 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
269 an client is killed from the SILC Network. Updated the protocol
272 Added new function silc_server_send_notify_killed to the
273 silcd/packet_send.[ch].
275 * Added function silc_server_packet_relay_notify to relay notify
276 packets that are destined directly to a client. In this case
277 the server does not process the notify packets but merely relays
278 it to the client. Affected file silcd/packet_send.[ch].
280 Added also silc_server_packet_process_relay_notify to check
281 whereto relay the notify. Affected file is
282 silcd/packet_receive.[ch].
284 * Implemented the KILL command to the server.
288 * Added the backup schema desgined last fall to the protocol
289 specs for everyone to see. The specification is in the
290 *-spec-xx.txt draft and the packet type definitions for the
291 backup routers is in *-pp-xx.txt draft. Thusly, added also
292 new packet type SILC_PACKET_CELL_ROUTERS.
294 * A big security problem in the implementation discovered. The
295 signoff of an client did not cause new channel key generation
296 which it of course should've done. The channel keys must be
297 always re-generated when client leaves (or signoffs) the channel.
298 The silc_server_remove_from_channels funtion now handles
299 the channel key re-generation.
301 * Added `sender' argument to the silc_server_send_notify_on_channels
302 to not to send the client provided as argument. Affected file
303 silcd/packet_send.[ch].
305 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Implemented OPER and SILCOPER commands into the server and
310 * Added silc_auth_verify and silc_auth_verify_data to verify
311 the authentication directly from the authentication payload.
312 It supports verifying both passphrase and public key based
313 authentication. Affected file lib/silccore/silcauth.[ch].
315 * Added `hash' field to the SilcIDListData structure. It is the
316 hash negotiated in the SKE protocol. Affected file is
319 * Slight redesigning of the SilcAuthPayload handling routines.
320 Do not send SilcPKCS but SilcPublicKey as argument.
322 * Implemented the public key authentication support to the
323 serverconfig. The public key is loaded fromthe provided path
324 and saved as authentication data to void * pointer. Thus,
325 changed the unsigned char *auth_data to void *auth_data;
327 * Fixed SHUTDOWN command to send the reply before the server
328 is shutdown. :) Affected file silcd/command.c.
330 * Fixed fatal bug in CONNECT command. The hostname was invalid
331 memory and server crashed. Affected file silcd/command.c.
333 * Fixed fatal bug in CLOSE command. The server_entry became
334 invalid but was referenced later in the command. Affected file
337 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
339 * Fixed fatal bug in failure packet handling. Server ignored
340 the failure and thus crashed when it came.
344 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
347 that the command may be executed only once in (about) 2 seconds.
348 The old SILC_CF_LAG flag is same but allows command bursts up
349 to five before limiting.
351 Added the support for CF_LAG and CF_LAG_STRICT flags to the
352 server code. Various commands now includes the CF_LAG_STRICT
353 flag to disallow any kind of miss-use of the command.
355 * Fixed the silc_buffer_unformat to not to allocate any data
356 if the length of the data is zero. It used to allocate the
357 length + 1. Affected file lib/silcutil/silcbuffmt.c.
359 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Changed the format of AdminConnection configuration section
362 in the server. Added username of the admin to the format.
363 Affected files silcd/serverconfig.[ch].
365 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
366 to return admin configuration data by host, username and/or
369 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Implemented WHOWAS command to the server. Added the functions:
373 silc_server_command_whowas_parse,
374 silc_server_command_whowas_send_reply,
375 silc_server_command_whowas_from_client and
376 silc_server_command_whowas_from_server
378 * Added <Client ID> argument to the WHOWAS command reply. Updated
379 the protocol specs accordingly.
381 * Implemented WHOWAS command and command_reply to the client
384 Implemented the WHOWAS printing on the user interface.
386 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Added new argument to the WHOWAS command reply, the real name.
389 It is an optional argument. Updated the protocol specs.
391 * Added SilcIDCacheDestructor callback that is registered when
392 the SilcIDCache is allocated. The callback is called when
393 an cache entry in the ID Cache expires, or is purged from the
394 cache. Added into lib/silccore/idcache.[ch].
396 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
397 to destruct the client entries when the cache entry expires.
398 Other ID Cache's in server and in the client library ignores
401 * If the ID Cache entry's `expire' field is zero then the entry
402 never expires. Added boolean `expire' argument to the
403 silc_idcache_add function in the lib/silccore/idcache.[ch].
404 If it is TRUE the default expiry value is used.
406 * Added silc_server_free_client_data_timeout that is registered
407 when client disconnects. By default for 5 minutes we preserve
408 the client entry for history - for WHOWAS command.
410 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Added support to the server to enforce that commands are not
413 executed more than once in 2 seconds. If server receives
414 commands from client more frequently, timeout is registered
415 to process the commands. Affected file silcd/command.c.
416 Added new function silc_server_command_process_timeout.
418 * Changed NICK_NOTIFY handling in client library to check that
419 if the client's nickname was changed, so there is no need to
420 resolve anything from the server.
422 * Removed error printing from the WHOIS and IDENTIFY commands.
423 If error occurs then it is ignored silently in the client library.
424 The application, however, may map the received error to
425 human readable error string. The application currently maps
426 the NO_SUCH_NICKNAME error to string.
428 * Made the command status message public to the application. Moved
429 them from lib/silcclient/command_reply.c to
430 lib/silcclient/command_reply.h. The application can map the
431 received command status to the string with the
432 silc_client_command_status_message function.
434 * Added check to the server to check that client's ID is same
435 as the Source ID in the packet the client sent. They must
438 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Added dist-bzip hook to the Makefile.am to make bzip2
441 compressed distributions.
443 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
445 * Server now enforces the maximum length for the nickname and
446 the channel as protocol specification dictates. 128 bytes for
447 nickname and 256 bytes for channel name.
449 * Moved the WHOIS printing to the application. The client libary
450 does not print out the WHOIS information anymore, the application
451 must do it. Renamed silc_client_command_reply_whois_print to
452 the silc_client_command_reply_whois_save.
454 The client's idle time is also sent to the application now, and
455 the idle is shown on screen.
457 * Added silc_client_command_reply_identify_save to save the
458 received IDENTIFY entries.
460 * Do not check for channel private keys in message sending and
461 reception if the channel does not have the PRIVKEY mode set.
462 Affected file lib/silclient/client_channel.c.
464 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
466 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
467 just surfaced after chaning the JOIN procedure.
469 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Added silc_client_get_clients_by_list to get client entries
472 from Client ID list, that is returned for example by JOIN
473 and USERS command replies. The application should use this
474 function for example when JOIN command reply is received to
475 resolve the clients already on the channel (library does not
476 do that anymore as USERS command reply is not used in the JOIN
477 procedure anymore). Affected files lib/silcclient/silcapi.h and
478 lib/silcclient/idlist.c.
480 * JOIN command reply and USERS command reply returns now SilcBuffer
481 pointers instead of unsigned char pointers when returning
482 the client list and mode list.
484 * Added <Client ID> argument to the JOIN command reply, mainly
485 for the server to identify for which client the command was
486 originally sent. Updated protocol specs accordingly.
488 * Added SilcDlist private_key pointer to the SilcChannelEntry
489 in the client to support the channel private keys. Affected
490 file is lib/silcclient/idlist.h.
492 * Added SilcChannelPrivateKey argument to the function
493 silc_client_send_channel_message so that application can choose
494 to use specific private ke if it wants to. If it is not provided,
495 the normal channel key is used, unless private keys are set.
496 In this case the first (key that was added first) is used
497 as the encryption key.
499 * Implemented the support for channel private key handling.
500 Implemented the following functions:
502 silc_client_add_channel_private_key,
503 silc_client_del_channel_private_keys,
504 silc_client_del_channel_private_key,
505 silc_client_list_channel_private_keys and
506 silc_client_free_channel_private_keys
508 Affected file lib/silcclient/client_channel.c.
510 * Added the support for the private keys in the channel message
511 sending and encryption and in the message reception and
512 decryption. Affected funtions are
513 silc_client_send_channel_message and silc_client_channel_message.
515 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Added SKE's key verify callback to the client library's
518 KE protocol context. Affected files lib/silcclient/protocol.[ch].
520 * Removed the statement that server (or router) must send USERS
521 command reply when joining to the channel so that the client
522 knows who are on the channel. Instead, the client list and
523 client's mode list is now sent in the JOIN command reply to the
524 client who joined channel. This is better solution.
526 * Added function silc_server_get_users_on_channel and function
527 silc_server_save_users_on_channel to the silcd/server.[ch].
529 * Removed function silc_server_command_send_users from the
532 * Do not show topic on the client library anymore. The topic is
533 sent in the command reply notify to the application and the
534 application must show the topic now.
536 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Added client searching by nickname hash into the IDENTIFY and
539 WHOIS commands in the server as they were clearly missing from
540 them. Affected file is silcd/command.c.
542 * Fixed a bug in private message receiving in the client library.
543 The remote ID was freed and it wasn't supposed, now it is
546 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Minor fix to the channel payload; allocate the data area, as it
549 needs to be of specific length.
551 * If the key agreement port is zero then the operating
552 system will define the bound port. Affected files are
553 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
555 * Added new function silc_channel_payload_decrypt into the file
556 lib/silccore/silcchannel.[ch].
558 * Moved the channel message etc, check from silc_packet_decrypt
559 to applications. The library calls now a generic
560 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
561 when the packet is either normal or special. This was done to
562 allow more wide range of checking that was not allowed when
563 the code was in library. Now applications can do virtually any
564 checks to the packet and return to the library the decision how
565 the packet should be processed. Affected files are
566 lib/silccore/silcpacket.[ch].
568 Added silc_server_packet_decrypt_check to the server and
569 silc_client_packet_decrypt_check to the client library.
571 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
572 to send with specified source and destination information.
574 * Channel message delivery between routers was broken after the
575 channel key distribution was fixed earlier. The channel key
576 was used be to distributed to other routers as well which is not
577 allowed by the protocol. Now this is fixed and channel keys
578 really are cell specific and the channel message delivery between
579 routers comply with the protocol specification.
581 * Fixed various commands in server to check also the global list
582 for the channel entry and not just the local list. The affected
583 file silcd/command.c.
585 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * Added assert()s to buffer formatting and unformatting routines
588 to assert (if --enable-debug) when error occurs. Affected
589 file: lib/silcutil/silcbuffmt.c.
591 * Changed to auto-reconnect to check whether the remote host is
592 router and register the re-connect timeout if it is. It used
593 to check that whether we are normal server, but router must do
594 auto-reconnect with another router as well. Affected file
597 * Removed the [<key len>] option from CMODE command as the cipher
598 name decides the key length, nowadays. See the defined ciphers
599 from the protocol specification.
601 * Added [<hmac>] option to the CMODE command to define the HMAC
602 for the channel. Added SILC_CMODE_HMAC channel mode.
604 * Added [<hmac>] option for the JOIN command so that user can
605 select which HMAC is used to compute the MACs of the channel
608 * Added Hmac field to the Channel Message Payload. The integrity
609 of plaintext channel messages are now protected by computing
610 MAC of the message and attaching the MAC to the payload. The
611 MAC is encrypted. Now, it is clear that this causes some
612 overhead to the size of the packet but rationale for this is that
613 now the receiver can verify whether the channel message decrypted
614 correctly and also when private keys are set for the channel the
615 receiver can decrypt the packet with several keys and check from
616 the MAC which key decrypted the message correctly.
618 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
619 lib/silccrypt/silccipher.[ch].
621 * Added silc_hash_len to return the digest length into the
622 lib/silcrypt/silchash.[ch].
624 * Rewrote parts of Silc Channel Payload interface in the
625 lib/silccore/silcchannel.[ch]. The encode function now also
626 encrypts the packet and parse function decrypts it.
628 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Fixed a minor formatting bug in the SKE's key material processing.
631 It actually might have processed the keys wrong way resulting
634 * Redefined the mandatory HMAC algorithms and added new algorithms.
635 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
636 and hmac-md5 truncated to 96 bits. The mandatory is now
637 hmac-sha1-96. Rest are optional (including the one that used
638 to be mandatory). Rationale for this is that the truncated HMAC
639 length is sufficient from security point of view and can actually
640 make the attack against the HMAC harder. Also, the truncated
641 HMAC causes less overhead to the packets. See the RFC2104 for
644 * Added new [hmac] configuration section. The SKE used to use
645 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
646 is of course wrong. The official names that must be proposed in
647 the SKE are the ones defined in the protocol specification
648 (hmac-sha1-96 for example). The user can configure any hmac
649 using any hash function configured in the [hash] section. At
650 least, the mandatory must be configured.
652 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
654 * Added HMAC list to the SKE proposal list. It has now both
655 hash algorithm list and HMAC list. This makes the protocol
656 incompatible with previous versions. The SKE now seems to work
657 the way it is supposed to work, for the first time actually.
659 * Defined plain Hash algorithms to the protocol specification.
662 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Implemented support for key agreement packets into the server.
665 Added functions silc_server_key_agreement and
666 silc_server_send_key_agreement. Other than these functions,
667 server has nothing to do with this packet.
669 * Added support for private message key packets into the server.
670 Added functions silc_server_private_message_key and
671 silc_server_send_private_message_key.
675 * Changed the silc_[client|server]_protocol_ke_set_keys to be
676 called in the protocol's final callback instead in the END
677 protocol state. This makes a little more sense and in the same
678 time in client we can use the same protocol routines for normal
679 key exchange and to key agreement packet handling as well.
681 * Added to both client's and server's KE protocol context the
682 SilcSKEKeyMaterial pointer to save the key material. We will
683 bring the key material to the protocol's final callback by doing
684 this. The final callback must free the key material.
686 * Added SKE's packet_send callback into client's KE protocol
687 context so that the caller can choose what packet sending function
688 is used. This way we can use different packet sending when
689 doing normal SKE when doing key agreement packet handling (in
690 the key agreement packet handling we do not want to encrypt
693 * Implemented the responder side of the key agreement routines
694 in the client. The client can now bind to specified port and
695 accept incoming key negotiation. The key material is passed
696 to the application after the protocol is over.
698 * Implemented the processing of incoming Key Agreement packet
699 in the client. Added function silc_client_key_agreement to
702 * Implemented the intiator side of the key agreement routines
703 in the client. The client can now initiate key agreement with
704 another remote client. The key material is passed to the
705 application after the protocol is over.
707 * Created client_keyagr.c to include all the key agreement
710 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
711 SILC_TASK_CALLBACK except that it is not static.
713 * Created client_notify.c and moved the Notify packet handling
714 from the client.[ch] into that file.
716 * Created client_prvmsg.c and moved all private message and
717 private message key routines from the client.[ch] into that file.
719 * Create client_channel.c and moved all channel message and
720 channel private key routines from the client.[ch] into that file.
722 * Changed silc_client_get_client_by_id_resolve to resolve with
723 WHOIS command instead of IDENTIFY command, in the file
724 lib/silclient/idlist.c.
726 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
728 * Implemented the SKE's responder side to the Client library.
730 * When FAILURE is received to the protocol do not trust it
731 blindly. Register a timeout to wait whether the remote closes
732 the connection as it should do it, only after that process the
733 actual failure. This was changed to both client and server.
735 * Added client_internal.h to include some of the structures
736 there instead of client.h in lib/silcclient/.
738 * Added function silc_task_unregister_by_callback to unregister
739 timeouts by the callback function.
741 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Some "Incomplete WHOIS info" errors has been appearing on the
744 log files. Took away the entry->userinfo check from WHOIS
745 reply sending. The entry->userinfo is now " " if client did not
746 provide one. I thought this was fixed earlier but something
747 is wrong still. Let's see if the error still appears.
749 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Fixed a minor bug in the login when the channel key is
752 re-generated in the server. It used to generate the key in
753 wrong order and thus caused problems in the channel traffic.
755 * Fixed a minor bug in channel key distsribution after
756 KICK command. The key was not sent to the router even though
759 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Added silc_ske_process_key_material_data as generic routine
762 to process any key material as the SILC protocol dictates. The
763 function is used by the actual SKE library but can be used by
764 applications as well. This relates to the private message keys
765 and the channel private keys since they must be processed the
766 same way the normal SILC session keys. The protocol dictates
767 this. Affected files: lib/silcske/silcske.[ch].
769 Added also silc_ske_free_key_material to free the
770 SilcSKEKeyMaterial structure.
772 * Defined silc_cipher_set_key function to set the key for
773 cipher without using the object's method function. The affected
774 files: lib/silccrypt/silccipher.[ch].
776 * Implemented silc silc_client_add_private_message_key,
777 silc_client_add_private_message_key_ske,
778 silc_client_del_private_message_key,
779 silc_client_list_private_message_keys and
780 silc_client_free_private_message_keys functions in the
783 Added functions silc_client_send_private_message_key to send
784 the Private Message Key payload and silc_client_private_message_key
785 to handle incoming Private Message Key payload.
787 * Added Cipher field to the Private Message Key payload to set
788 the cipher to be used. If ignored, the default cipher defined
789 in the SILC protocol (aes-256-cbc) is used.
791 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Removed lib/silcclient/ops.h file.
795 Redefined parts of the SILC Client Library API. Created new
796 file silcapi.h that deprecates the ops.h file and defines the
797 published Client Library API. Defined also private message key
798 API and channel private key API into the file.
800 This is the file that the application must include from the
801 SILC Client Library. Other files need not be included by
802 the application anymore.
804 * Added new key_agreement client operation callback and also
805 defined the Key Agreement library API for the application.
807 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
810 is used by clients to request key negotiation between another
811 client in the SILC network. If the negotiation is started it
812 is performed using the SKE protocol. The result of the
813 negotiation, the secret key material, can be used for example
814 as private message key.
816 Implemented the Key Agreement payload into the files
817 lib/silccore/silauth.[ch].
819 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
821 * Redefined ciphers for the SILC protocol. Added some new ciphers
822 and defined the key lengths for the algorithms. Changed the
823 code accordingly. The default key length is now 256 bits.
825 * Fixed SKE key distribution function silc_ske_process_key_material
826 when the key length is more than 128 bits. The default key
827 length in SILC is now 256 bits.
829 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
830 to indicate unsupported algorithm.
832 * Renamed rijndael.c to aes.c and all functions as well.
834 * Fixed a long standing channel key setting bug in client library.
835 Weird that it has never surfaced before.
837 * Fixed bug in channel deletion. If the entire channel is removed
838 then it must also delete the references of the channel entry
839 from the client's channel list as the client's channel entry and
840 the channel's client entry share same memory.
842 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Implemented CONNECT and SHUTDOWN commands in the client.
846 * Implemented CLOSE command to the client.
848 * Added the function silc_idlist_find_server_by_name into the
849 files silcd/idlist.[ch].
851 Added the function silc_idlist_find_server_by_conn into the
852 files silcd/idlist.[ch].
854 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * DIE command was renamed to SHUTDOWN. Updated the both code
859 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
860 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
862 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
865 * Added function silc_server_create_connection function to create
866 connection to remote router. My server implementation actually
867 does not allow router to connect to normal server (it expects
868 that normal server always initiates the connection to the router)
869 so the CONNECT command is only good for connecting to another
872 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
875 or some other client was kicked from the channel.
877 Implemented the handling of the notify type to both client
880 Implemented silc_server_send_notify_kicked to send the KICKED
881 notify. It is used to send it to the server's primary router.
883 * Implemented the KICK command into server and client.
885 * Added `query' argument to the silc_idlist_get_client function
886 to indicate whether to query the client from server or not if
889 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
890 to indicate that the client is not channel founder.
894 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Removed the rng context from SilcPacketContext structure and
897 changed that the packet routine uses the Global RNG API.
899 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Added support for quit message that client can "leave" on the
902 channel when it quits the SILC. It is ditributed inside the
903 SILC_NOTIFY_TYPE_SIGNOFF notify type.
905 Added silc_server_free_client_data that will take the
906 signoff message as argument.
908 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
910 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Updated parts of the protocol specification to keep it up
915 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
918 payloads in one packet.
920 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
921 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
922 use now the new List flag.
924 * Also deprecated the following packet types: REPLACE_ID,
925 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
927 * Added list support for Notify packet in server.
929 * Added silc_server_send_notify_channel_change to send the
930 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
931 the silc_server_send_replace_id.
933 * Added silc_server_send_notify_nick_change to send the
934 NICK_CHANGE notify type. Deprecates the function
935 silc_server_send_replace_id.
937 * Added silc_server_send_notify_join to send the JOIN notify type.
938 Deprecates the function silc_server_send_new_channel_user.
940 * Added silc_server_send_notify_leave to send LEAVE notify type.
941 Deprecates the function silc_server_send_remove_channel_user.
943 * Added silc_server_send_notify_cmode and
944 silc_server_send_notify_cumode to send CMODE and CUMODE notify
945 types. Deprecates the silc_server_send_set_mode function.
947 * Added SERVER_SIGNOFF notify type to indicate that server has
948 quit. This means that all clients on the channel from that
949 server will drop. This can be also used when netsplit happens.
951 Deprecated REMOVE_ID packet type since it is not needed anymore
954 Added silc_server_send_notify_server_signoff to send the
955 SERVER_SIGNOFF notify type. Deprecates the function
956 silc_server_send_remove_id.
958 Added also silc_server_send_notify_signoff to send the
961 * Employed the PKCS #1. It is the mandatory way to do RSA in the
962 SILC protocol from this day on. Changed the protocol
963 specification as well.
965 * Added silc_server_send_notify_topic_set to send TOPIC_SET
966 notify type. It is used between routers to notify about
967 topic changes on a channel.
969 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
972 * Partly updated the protocol specification to comply with the
973 changes now made. It is still though a bit outdated.
975 * The JOIN notify type now takes one extra argument <Channel ID>.
976 The packet used to be destined to the channel but now the
977 JOIN type may be sent as list thus it is impossible to
978 destine it to any specific channel. By adding this argument
979 it is again possible.
981 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added CREDITS file. The CHANGES and CREDITS file will appear
984 in the distribution as well.
986 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
989 types in the server's silcd/packet_receive.c.
991 * Implemented CMODE and CUMODE to work in router environment.
993 * Fixed minor encoding and decoding buglet from the
994 lib/silccore/silcmode.c.
996 * Fixed buffer overflow from lib/silcclient/command.c in USERS
999 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1001 * Changed all SilcConfigServer* and silc_config_server* to
1002 SilcServerConfig* and silc_server_config*, respectively.
1005 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Associated the ID (client or server ID) to the Authentication
1008 Payload to avoid any possibility of forging. Updated the
1009 protocol specification and the code accordingly.
1011 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1013 * The RSA key length is now save to the RsaKey context in the
1014 key generation process in lib/silccrypt/rsa.c. The key length
1015 is now used to figure out the maximum size of the block allowed
1016 to be encrypted/signed.
1018 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1019 is equivalent to the silc_mp_mp2bin but does not allocate any
1022 * Changed silc_mp_mp2bin API to take length argument. If it is
1023 non-zero then the buffer is allocated that large. If zero, then
1024 the size is approximated using silc_mp_sizeinbase, which however
1027 * Created Global RNG API which is global RNG that application can
1028 initialize. After initializing, any routine anywhere in the
1029 code (including library) can use RNG without allocating a new
1030 RNG object. This was done to allow this sort of use of the
1031 RNG in code that has no chance to allocate RNG object. All
1032 applications currently allocate this and many routines in the
1033 library use this. Affected file lib/silccrypt/silcrng.[ch].
1035 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1036 it to use the Global RNG API.
1038 * Defined Authentication Payload into protocol specification that
1039 is used during SILC session to authenticate entities. It is
1040 used for example by client to authenticate itself to the server
1041 to obtain server operator privileges.
1043 Implemented this payload into the lib/silccore/silcauth.[ch].
1044 Implemented also routines for public key based authentication
1045 as the new protocol specification dictates.
1047 Moved definitions of different authentication methods from
1048 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1050 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1051 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1052 silc_pkcs_verify_with_hash functions into the file
1053 lib/silccrypt/silcpkcs.[ch].
1055 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * The client entry's userinfo pointer must be always valid.
1058 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1059 will fail since it requires the userinfo. Now, the userinfo
1060 is allocated as "" if actual userinfo does not exist. Actually,
1061 it must exist and it is totally Ok to drop client connections
1062 that does not announce the userinfo. However, we will make
1063 this workaround for now.
1065 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1066 to return the remote port by socket.
1068 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1071 SILC_SERVER_PENDING_EXEC and added an new macro
1072 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1073 data or when error occurs while processing the pending command.
1075 Added new argument `destructor' into silc_server_command_pending
1076 and to the SilcServerCommandPending object. This destructor is
1077 now called after calling the pending callback or if error occurs
1078 immediately. If error occurs the actual pending callback won't
1079 be called at all - only the destructor. The destructor may be
1080 NULL if destructor is not needed.
1082 All this applies for client library code as well. Similar
1083 changes were made there as well for the pending commands.
1085 In the client, the application must now allocate the
1086 SilcClientCommandContext with the silc_client_command_alloc
1089 * Added reference counter to the SilcServerCommandContext. Added
1090 function silc_server_command_alloc and silc_server_command_dup
1093 Same type of functions added to the client library for the same
1096 * Removed the cmd_ident from IDListData away since it is now
1097 global for all connections. It is the command identifier used
1098 in command sending and with pending commands. The affected file
1101 * Added reference counter to the SilcSocketConnection objecet to
1102 indicate the usage count of the object. The object won't be
1103 freed untill the reference counter hits zero. Currently only
1104 server uses this, and client ignores it. The client must be
1105 set to use this too later. The affected files are
1106 lib/silccore/silcsockconn.[ch]. Added also the function
1107 silc_socket_dup to increase the reference counter.
1109 This was mainly added because it is possible that the socket
1110 is removed underneath of pending command or other async
1111 operation. Now it won't be free'd and proper DISCONNECTING
1112 flags, etc. can be set to avoid sending data to connection that
1113 is not valid anymore.
1115 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1116 the connection. After that it sets SILC_SET_DISCONNECTED.
1117 It is, however, possible that the socket data is not still freed.
1118 The silc_server_packet_process now checks that data is not
1119 read or written to connection that is DISCONNECTED. The socket
1120 get's freed when the reference counter hits zero.
1122 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Changed the client operation API: channel_message operation's
1125 `sender' is now the client entry of the sender, not the nickname
1126 and the `channel' is the channel entry, not the channel name.
1128 In the private_message operation the `sender' is now also the
1129 client entry of the sender not the nickname.
1131 Affected file is lib/silcclient/ops.h and all applications
1132 using the client operations.
1134 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1136 * Moved the calling of ops->connect() from connect_to_server_final
1137 into receive_new_id functin since that is the point when the
1138 client is actually allowed to send traffic to network. The
1139 affected file is lib/silcclient/client.c.
1141 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1144 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1145 (if needs broadcasting) instead of broadcasting the packets one
1146 by one which would make a burst in the network traffic.
1148 * Added `broadcast' argument to the functions in silcd/server.[ch]
1149 silc_server_create_new_channel[_with_id] to indicate whether
1150 to send New Channel packet to primary router.
1152 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added new function into the silcd/server.[ch] files:
1155 silc_server_create_new_channel_with_id to create new channel with
1156 already existing Channel ID.
1158 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1159 lib/silccore/silcpacket.h. This packet is used t send list of
1160 Set Mode payloads inside one packet. Server uses this to set
1161 the modes for the channels and clients on those channels, that it
1162 announced to the router when it connected to it. The protocol
1163 specification has been updated accordingly.
1165 * The silc_server_new_channel did not handle the packet coming
1166 from normal server as it normally does not send that. However,
1167 when it announces its channels it does send it. Implemented
1168 the support for that.
1170 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1171 into the file lib/silccore/id.h.
1173 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Fixed memory leaks in the functions silc_idlist_del_client,
1176 silc_idlist_del_channel and silc_idlist_del_server in the file
1177 silcd/idlist.c. All of those leaked like a sieve.
1179 * Fixed some small memory leaks in the client's function
1180 silc_client_notify_by_server.
1182 * Added functions into silcd/server.c: silc_server_announce_clients,
1183 silc_server_announce_channels and silc_server_announce_server.
1184 These functions are used by normal and router server to announce
1185 to its primary router about clients, channels and servers (when
1186 router) that we own. This is done after we've connected to the
1189 These functions effectively implements the following packet types:
1190 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1191 and SILC_PACKET_NEW_ID_LIST.
1193 * Added new functions into the silcd/packet_receive.[ch]:
1194 silc_server_new_id_list, silc_server_new_channel_list and
1195 silc_server_new_channel_user_list to handle the incoming
1196 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1198 * Added support of changing Channel ID in the function
1199 silc_server_replace_id. If the server that announces a channel
1200 to the router already exists in the router (with same name but
1201 with different Channel ID), router is responsible to send
1202 Replace ID packet to the server and force the server to change
1203 the Channel ID to the one router has.
1205 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1206 client that the Channel ID has been changed by the router. The
1207 normal server sends this to the client. Client must start using
1208 the new Channel ID as the channel's ID.
1210 Implemented handling of this new type into lib/silcclient/client.c
1211 into the function silc_client_notify_by_server.
1213 * Added new function silc_idlist_replace_channel_id into the files
1214 silcd/idlist.[ch] to replace the Channel ID.
1216 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Call silc_server_command_identify_check always when processing
1219 the IDENTIFY command in silcd/command.c
1221 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1224 send keepalive packets. The packet can be sent by clients,
1225 servers and routers.
1227 Added function silc_socket_set_heartbeat into the file
1228 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1229 If not set, the heartbeat is not performed. The actual
1230 heartbeat is implemented in the low level socket connection
1231 library. However, application is responsible of actually
1234 Added silc_server_send_heartbeat to send the actual heartbeat
1235 packet into silcd/packet_send.[ch]. Server now performs
1236 keepalive with all connections.
1238 * Added silc_task_get_first function into lib/silcutil/silctask.c
1239 to return the timeout task with shortest timeout. There was a bug
1240 in task unregistration that caused problems. TODO has been
1241 updated to include that task system must be rewritten.
1243 * The client library will now resolve the client information when
1244 receiving JOIN notify from server for client that we know but
1245 have incomplete information.
1247 * Rewrote parts of silc_server_remove_from_channels and
1248 silc_server_remove_from_one_channel as they did not remove the
1249 channel in some circumstances even though they should've.
1251 * Encryption problem encountered in server:
1253 The LEAVE command used to send the Channel Key packet to the
1254 router immediately after generating it. However, the code
1255 had earlier sent Remove Channel user packet but not immediately,
1256 ie. it was put to queue. The order of packets in the router
1257 was that Channel Key packet was first and Remove Channel User
1258 packet was second, even though they were encrypted in the
1259 reverse order. For this reason, MAC check failed. Now, this
1260 is fixed by not sending the Channel Key packet immediately but
1261 putting it to queue. However, this is more fundamental problem:
1262 packets that are in queue should actually not be encrypted
1263 because packets that are sent immediately gets encrypted
1264 actually with wrong IV (and thus MAC check fails). So, packets
1265 that are in queue should be encrypted when they are sent to
1266 the wire and not when they put to the queue.
1268 However, the problem is that the current system has not been
1269 designed to work that way. Instead, the packet is encrypted
1270 as soon as possible and left to the queue. The queue is then
1271 just purged into wire. There won't be any fixes for this
1272 any time soon. So, the current semantic for packet sending
1275 o If you send packet to remote host and do not force the send
1276 (the packet will be in queue) then all subsequent packets to the
1277 same remote host must also be put to the queue. Only after the
1278 queue has been purged is it safe again to force the packet
1281 o If you send all packets immediately then it safe to send
1282 any of subsequent packets through the queue, however, after
1283 the first packet is put to queue then any subsequent packets
1284 must also be put to the queue.
1286 Follow these rules and everything works fine.
1288 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Added new function silc_server_remove_clients_by_server to
1291 remove all client entries from ID list when the server connection
1292 is lost. In this case it is also important to invalidate all
1293 client entires as they hold the invalid server entry. This
1294 fixes fatal bug when server has lost connection and will reconnect
1297 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1299 * Made some sanity checks to silc_server_daemonise like to check
1300 whether the requested user and group actually exists.
1302 * Added sanity check to SKE's silc_ske_responder_finish to check
1303 that the public and private key actually is valid.
1305 * Invalidate the client's nickname when receiving Replace ID
1306 packet and the Client ID is being replaced. This means that the
1307 server will query the nickname if someone needs it (client)
1310 * Sort the ID Cache in client library when the ID Cache data
1311 has changed (needs sorting).
1313 * Do not allow for SILC client to create several connections to
1314 several servers. The client does not support windows right now
1315 and generating multiple connections causes weird behaviour.
1317 Irssi-silc client does support windows and can handle several
1318 connections without problems, see: www.irssi.org and SILC plugin.
1320 * Fixed some places where client was added to the IDList. The
1321 rule of thumb is following (in order to get everything right):
1322 If the client is directly connected local client then the
1323 `connection' argument must be set and `router' argument must be
1324 NULL to silc_idlist_add_client function. If the client is not
1325 directly connected client then the `router' argument must
1326 bet set and the `connection' argument must be NULL to the
1327 silc_idlist_add_client function.
1329 * The funtion silc_server_packet_send_local_channel actually did
1330 not check whether the client was locally connected or not. It
1331 does that now. Fixed a bug related to LEAVE command.
1333 * Fixed Remove Channel User payload parsing bug in server's
1334 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1336 * The server's silc_server_save_channel_key now checks also the
1337 global ID list for the channel as it might not be in the local
1338 list. Fixed a bug related to LEAVE command.
1340 * Is this the end of the [<unknown>] buglet that has been lurking
1341 around for a long time? A little for loop fix in server's
1342 silc_server_command_whois_parse that is used by both IDENTIFY
1343 and WHOIS command. At least, this was a clear bug and a cause
1344 of one type of [<unknown>] buglet.
1346 * WHOIS and IDENTIFY commands call the function
1347 silc_server_command_[whois/identify]_check function even if
1348 we are not router server.
1350 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added --with-gmp configuration option. If set the GMP
1353 is always compiled in the SILC source tree. If not set then
1354 it is checked whether the system has the GMP3 installed. If
1355 it has then the GMP won't be compiled (the system's headers
1356 and library is used), if it doesn't have it then the GMP is
1357 compiled in the SILC source tree.
1359 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Changed RSA private exponent generation to what PKCS #1
1362 suggests. We try to find the smallest possible d by doing
1363 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1364 not security fix but optimization.
1366 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Added new config entry [Identity] to fork the server and run
1369 it as specific user and group. A patch from Bostik.
1371 * Imported Dotconf configuration library into lib/dotconf.
1372 This will be used to create the SILC configuration files later.
1373 It will appear in the distsribution after this commit.
1375 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * A big code auditing weekend happening. Auditing code for
1378 obvious mistakes, bugs and errors. Also, removing any code
1381 Removed files for being obsolete:
1383 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1384 inline in the file lib/silcutil/silcbuffer.h)
1386 o lib/silcutil/silcbufutil.c (the header has inline versions)
1388 Changed code to fix possible error conditions:
1390 o The buffer formatting routines now check that the destination
1391 buffer really has enough space to add the data. This applies for
1392 both buffer formatting and unformatting
1393 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1394 unformatting was changed to accomodate following rules:
1395 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1396 sent to the function while XXX_*STRING will not allocate or copy
1397 the data into the buffer. Instead it sets the pointer from the
1398 buffer into the pointer sent as argument (XXX_*STRING used to
1399 require that the pointer must be allocated already). This change
1400 makes this whole thing a bit more consistent and more optimized
1401 (note that the data returned in the unformatting with XXX_*STRING
1402 must not be freed now). The routines return now -1 on error.
1404 o Tried to find all code that use buffer_format and buffer_unformat
1405 and added return value checking to prevent formatting and
1406 especially unformatting errors and possible subsequent fatal
1409 o Changed ske->x and ske->KEY to mallocated pointers in
1410 lib/silcske/silcske.h. Fixed possible data and memory leak.
1412 o Added return value checking to all *_parse* functions. Fixed
1413 many memory leaks as well.
1415 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1416 so that buffer overflows would not happen. All code now also
1417 checks the return value as it can fail.
1419 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Added reconnection support to server if the normal server looses
1422 its connection to the router (for example if router is rebooted).
1423 The server performs normal reconnection strategy implemented
1424 to the server. Affected file silcd/server.c.
1426 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Added new packet type SILC_PACKET_SET_MODE that is used to
1429 distribute the information about changed modes (for clients,
1430 channels and clients channel modes) to all routers in the
1431 network. Updated the protocol specification accordingly.
1433 Added functions into silcd/packet_send.c and
1434 silcd/packet_receive.c: silc_server_send_set_mode,
1435 silc_server_set_mode.
1437 Added new files silcmode.[ch] into lib/silccore that implements
1438 the encoding and decoding of Set Mode Payload. Added new type
1439 SilcSetModePayload. Moved the definitions of different modes
1440 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1442 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Oops, a little mistake in server's connection authentication
1445 protocol. The protocol is not ended with FAILURE but with
1446 SUCCESS if the authentication is Ok. :) Affected file is
1449 * Implemented NICK_CHANGE notify handling in server in the file
1450 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1451 the local clients on the channel. After the changing nickname
1452 in router environment snhould work and the [<unknown>] nickname
1453 should appear no more.
1455 The silc_server_replace_id function that receives the Replace ID
1456 payload now sends the NICK_CHANGE notify type also in the file
1457 silcd/packet_receive.c
1459 * Changed WHOIS and IDENTIFY command to support the maximum amount
1460 of arguments defined in protocol specs (3328 arguments). This
1461 fixed a bug that caused problems when there were more than three
1464 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1466 * Added extra parameter, command identifier, to the
1467 silc_client_send_command so that explicit command identifier
1470 Changed that ID list routines uses specific command identifier
1471 when sending WHOIS/IDENTIFY requests to the server so that they
1472 can be identified when the reply comes back.
1474 Affected files lib/silcclient/command.[ch],
1475 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1477 * Added `sender' argument to silc_server_packet_send_to_channel
1478 to indicaet the sender who originally sent the packet to us
1479 that we are now re-sending. Ignored if NULL. Affected file
1480 silcd/packet_send.[ch].
1482 * Added some server statistics support in silcd/server_internal.h
1483 SilcServerStatistics structure and around the server code. Also
1484 send some nice statistics information when client is connecting
1487 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Fixed channel ID decoding in server's JOIN command reply in
1490 silcd/command_reply.c
1492 * Fixed braodcasting of replace ID payload to not to send it if
1493 we are standalone server in silcd/packet_receive.c.
1495 * Fixed all channel message sending routines to not to send
1496 packets to clients that has router set, since they are routed
1497 separately in the same function earlier. Affects file
1498 silcd/packet_send.c and all channel packet sending functions.
1500 * In USERS reply, res_argv[i] are not allocated, the table
1501 is allocated. Thus changed that free the table, not its
1504 * In server's whois_check and identify_check if the client is
1505 locally connected do not send any WHOIS commands - they are not
1508 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Fixed some minor bugs in client when sending WHOIS command. The
1511 arguments was in wrong order.
1513 * Removed statis function add_to_channel from server in
1514 silcd/command.c that was previously used with the joining but
1517 * Tested USERS command in router environment successfully with two
1518 routers, two servers and two clients.
1520 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Reorganized the USERS command and command reply in client library
1523 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1524 When the command is given by user we register a pending command
1525 callback that will reprocess the command after the reply has been
1526 received from the server. When reprocessing the packet we then
1527 display the information. Thus, the USERS information is displayed
1528 now in the command callback instead of in the command reply
1529 callback. The processing of the command is same as previously
1530 when server has sent the command reply in the JOINing process.
1532 * Added to USERS command in silcd/command_reply.c to join the client,
1533 we didn't use to know about, to the channel after we've created
1534 a client entry for it. Also, for clienet we did know already still
1535 check whether it is on the channel or not and add it if not.
1537 * Removed silc_server_command_join_notify as the function and its
1540 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Changed the client's pending command handling to the same as the
1543 server's pending command handling. It is also now possible to
1544 execute command reply functions from other command reply
1545 function as the function callbacks for commands and command
1546 replies are one and same. The pending commands are not static
1547 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1548 in client connection context. Thus, pending commands are server
1549 connection specific as it is convenient.
1551 Changed the function silc_client_command_pending and
1552 silc_client_command_pending_del and added new function
1553 silc_client_command_pending_check. Removed the
1554 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1557 * Added cmd_ident, current command identifier, to the client
1558 connection context in lib/silcclient/client.h to keep track on
1559 command identifiers used in command sending. Client's command reply
1560 function handling now supports the mandatory command identifiers.
1562 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1563 funtions in client to fully support pending command callbacks.
1565 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1566 as one of the arguments to the application in the command reply
1569 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1570 before first releasing SILC but came back. Now it is removed again
1571 and should come back nomore. The FORWARDED flag was used only
1572 by the JOINing procedure by forwarding the command packet to router.
1573 Now, the JOINing procedure has been changed to more generic (due
1574 to various router environment issues) and FORWARDED is not needed
1575 anymore for anything. The protocol specification is yet to be
1578 Now, removed silc_server_packet_forward from server and the flag
1579 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1581 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Renamed NAMES command to USERS command. The NAMES was named that
1584 due to historical reasons. Now it is renamed. Also, rewrote
1585 parts of the USERS command. The nickname list is not sent anymore
1586 by the server. Only Client ID and mode lists are sent in the USERS
1587 command. Changed this also to the protocol specification.
1589 The client now resolves the names and stuff after it receives
1590 the USERS list from the server when joining to the channel.
1592 * WHOIS and IDENTIFY commands has been changed to support multiple
1593 Client ID's per command. One can now search for multiple users
1594 in the network by sending only one WHOIS or IDENTIFY command.
1595 Changed the code and the protocol specifications.
1597 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1598 uses silc_server_command_whois_parse to parse the request. */
1600 * If normal server, do not parse the WHOIS and IDENTIFY requests
1601 before sending it to the router. Saves some time.
1603 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Fixed JOIN command on client library. Wrong number of arguments
1606 used to crash the client.
1608 * Added silc_server_channel_has_global function to check whether
1609 channel has global users or not.
1611 * Added silc_server_channel_has_local function to check whether channel
1612 has locally connected clients on the channel.
1614 * The silc_server_remove_from_one_channel now checks whether the
1615 channel has global users or not after given client was removed from
1616 the channel. It also checks whether the channel has local clients
1617 on the channel anymore. If it does not have then the channel entry
1618 is removed as it is not needed anymore.
1620 * The silc_server_notify now checks on JOIN notify whether the joining
1621 client is one of locally connected or global. If it is global then
1622 the channel has now global users on the channel and that is marked
1623 to the channel entry. Also, it now saves the global client to
1624 global list who is joining and JOINs it to the channel. This is
1625 for normal server, that is.
1627 Changed silc_server_send_notify_on_channel,
1628 silc_server_packet_relay_to_channel and
1629 silc_server_packet_send_to_channel check if we are normal server
1630 and client has router set (ie. global client) do not send the
1631 message to that client, as it is already routed to our router.
1633 * Implemented LEAVE notify type handling in silc_server_notify
1636 * Tested LEAVE command in router environment successfully. Tested
1637 with two routers, two servers and two clients.
1641 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1643 * Implemented SIGNOFF notify type handling in silc_server_notify
1646 * silc_server_remove_id now removes the client entry from all channels
1647 it has joined and thusly sends SIGNOFF notify type.
1649 * Rewrote the NAMES list generation in server by removing two excess
1650 loops. The lists are created now inside one loop.
1652 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * silc_server_remove_channel_user checks now also global list
1655 for channel and client.
1657 * silc_server_new_channel_user checks now both local and global
1658 list for channel and client. Fixed a bug in client id decoding.
1659 Used to decode wrong buffer.
1661 * silc_server_channel_message checks now both local and global
1662 list for channel entry.
1664 * Tested channel joining (hence JOIN) in router environment
1665 successfully. Tested with two routers, two servers and two
1668 * Tested channel message sending in router environment successfully.
1670 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Added silc_server_save_channel_key into server.[ch] to save the
1673 received channel key in Channel Key payload processing. It is
1674 also used in JOIN command reply handling.
1676 Equivalent function silc_client_save_channel_key added into
1677 client.[ch] into client library.
1679 * Changed JOIN command reply to send information whether the channel
1680 was created or not (is existing already) and the channel key
1681 payload. Changed protocol specs accordingly.
1683 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1684 the request was sent by ID and not by nickname. Crashed on
1687 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1690 now correctly save the received data.
1692 * silc_server_free_sock_user_data now notifies routers in the
1693 network about entities leaving the network.
1695 At the same time implemented functions silc_server_remove_id
1696 and silc_server_send_remove_id to receive and send REMOVE_ID
1697 packets. The packet is used to notify routers in the network
1698 about leaving entities. The ID removed will become invalid in
1701 * Added function silc_idlist_del_server into server. Removes and
1702 free's server entry from ID list.
1704 * silc_server_private_message function now checks, if we are router,
1705 that the destination ID really is valid ID, naturally.
1707 * In router when NEW_ID packet is received (for new client) the
1708 hash of the Client ID is saved in the ID Cache but the
1709 client->nickname is set to NULL, instead of putting the hash
1712 IDENTIFY command now also checks that client->nickname must be
1713 valid. If it is not if will request the data from the server who
1714 owns the client. Added new function
1715 silc_server_command_identify_check.
1717 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1718 to set the command to already allocated Command Payload.
1720 * Tested private message sending in router environment with two
1721 routers, two servers and two clients. Fixed minor bugs and now
1724 * Fixed segfault from client's NAMES command. Used to crash if
1727 * Forwarded packets must not be routed even if it is not destined
1728 to the receiver. Changed server code comply with this.
1730 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Added `require_reverse_mapping' boolean value to ServerParams
1733 structure. If TRUE (not default) the server will require that
1734 the connecting host has fully qualified domain name.
1736 If the reverse mapping is not required and hostname could not be
1737 found the IP address is used as hostname.
1739 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Implemented version string checking to both client and server.
1742 The check is incomplete currently due to the abnormal version
1743 strings used in development version of SILC.
1745 * Changed all command functions in server to use the new
1748 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Changed char *data to unsigned char *data in ID Cache system to
1751 support binary data as ID Cache data. Changed code to support
1752 binary data in lib/silccore/idcache.c.
1754 * Renamed silc_server_packet_relay_command_reply to
1755 silc_server_command_reply as it is normal packet receiving
1756 function. Rewrote the function to accept command replys for
1757 servers and not only for clients.
1759 * Mark remote router always as registered server if we are connecting
1760 to it. Otherwise, commands sent by the router to us are ignored.
1762 * All ID List find routines now returns the ID Cache Entry pointer
1763 as well if requested.
1765 * WHOIS command works now in router environment, tested with two
1766 routers, two servers and two clients.
1768 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1769 in router environment (as it is almost equivalent to WHOIS) but
1770 hasn't been tested thoroughly. Added new functions:
1772 silc_server_command_identify_parse
1773 silc_server_command_identify_send_reply
1774 silc_server_command_identify_from_client
1775 silc_server_command_identify_from_server
1777 * Disabled route cache adding because adding two different ID's with
1778 same IP replaces the old cache entry thus giving wrong route.
1779 The entry->router->connection is always the fastest route anyway
1780 so route cache may not be needed. Of course, new routes maybe
1781 established after receiving the ID when the entry->router->connection
1782 might not be anymore the most optimal.
1784 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Add route cache for received ID for fast routing.
1788 * Added silc_server_packet_route to route received packet on router
1789 that is not destined to us.
1791 * Renamed silc_server_get_route to silc_server_route_get.
1793 * Added id_string and id_string_len fields into SilcServer to
1794 include encoded ServerID for fast comparing without excess
1795 encoding of the ID's.
1797 * Cleaned up WHOIS command on server side. Added following static
1800 silc_server_command_whois_parse
1801 silc_server_command_whois_check
1802 silc_server_command_whois_send_reply
1803 silc_server_command_whois_from_client
1804 silc_server_command_whois_from_server
1806 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1807 arguments in command replies. All command functions should be
1808 updated to use this macro.
1810 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Minor typo fixes on command reply handling on server.
1814 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * Added silc_server_command_add_to_channel internal routine to add
1817 the client to the channel after router has created the channel and
1818 sent command reply to the server.
1820 * Added generic silc_server_send_command to send any command from
1823 * Use static buffer with ID rendering instead of duplicating data.
1825 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Fixed a channel user mode bug when joining to a channel server gave
1828 everybody channel founder rights, oops.
1830 * We mark ourselves as the router of the incoming server connection
1831 if we are router ourselves. This way we can check in some packet
1832 sending functions whether it is locally connected server. For
1833 incoming router connections we put NULL.
1835 * For router sending packets locally means now always sending the
1836 packet cell wide; to local clients and local servers. For normal
1837 server sending packet locally means sending it to only local
1840 * Fixed the JOIN command to really work in router environment. If the
1841 channel is created it is always created by the router. Router is
1842 also responsible of making the initial joining to the channel,
1843 sending JOIN notify to the sending server and distributing
1844 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1845 does not exist server doesn't do anything else but forward the
1846 command to the router which performs everything.
1848 * Added silc_server_send_channel_key function to send the Channel Key
1851 * Added silc_server_create_channel_key to create new channel key. The
1852 channel key is now re-generated everytime someone joins or leaves
1853 a channel, as protocol dictates. Note: channel->key_len is the
1856 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1859 packet_receive.[ch] to separate packet sending and receiving
1860 routines. The server.[ch] now includes everything else including
1861 actual packet processing (writing and reading data) and other
1864 Renamed silc_server_private_message_send_internal to
1865 silc_server_send_private_message. The routine is still though
1866 used only to relay private messages as server does not send
1867 private messages itself.
1869 Renamed silc_server_new_channel to silc_server_create_new_channel
1870 and added new function sicl_server_new_channel that handles the
1871 incoming New Channel packet. Added also new sending function
1872 silc_server_send_new_channel to send New Channel Payload.
1874 * Added new function silc_server_notify to process incoming notify
1875 packet to the server/router. Server may then relay the notify
1876 to clients if needed.
1878 * Added new function silc_server_new_channel_user to process incoming
1879 New Channel User packet. Router will redistribute the packet and
1880 send JOIN notify to its local clients and locally connected servers
1881 if needed. Normal server will send JOIN notify to its local client
1882 on same channel when received this packet. Added also corresponding
1883 sending function silc_server_send_new_channel_user to sent the
1886 * Added boolean route argument to send_notif_to_channel and
1887 packet_send_to_channel functions to attempt to route the packet
1888 if it is TRUE and send only locally if it is FALSE.
1890 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * silc_server_replace_id now broadcasts the received replace ID
1893 packet if it is not broadcast packet already. The router must
1894 broadcast to inform other routers about changed ID.
1896 * Added backpointer to server's router into SilcServer context in
1897 silcd/server_internal.h.
1899 * Fixed silc_server_packet_broadcast to send correct broadcast
1902 * The channel key is now distributed to the local client as soon
1903 as it is received from the router (in router environment) so that
1904 no other packet may be sent for the channel until client has
1907 * silc_server_remove_channel_user now broadcasts the received
1908 Remove Channel User packet if it is not broadcast packet already.
1909 The router must broadcast to inform other routers about removed
1912 * Added users field into SilcPacketContext that is a reference count
1913 of the context. One can increase the reference count by calling
1914 silc_packet_context_dup which is now changed to just increase the
1915 reference count instead of duplicating the data. The reference
1916 count is decresed by calling silc_packet_context_free that will
1917 free the data after the reference count hits zero.
1919 For now on the packet context and everything allocated into it
1920 (including the raw packet from network) must be freed by calling
1921 the new silc_packet_context_free function. Added also new function
1922 silc_packet_context_alloc that must be used now to allocate the
1923 context. This also means that if a routine is asynchronous from
1924 silc_[client/server]_packet_parse_type the packet context must
1925 be duplicated by calling silc_packet_context_dup. Otherwise it
1926 gets free'd after silc_[client/server]_packet_parse_type returns.
1927 Also, one must remember that if packet is duplicated then its
1928 reference count must be decresed by calling the free function as
1929 many times as it was duplicated.
1931 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1932 from both client and server.
1934 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Made joining to a channel working in router environment.
1938 * Cleaned up JOIN command on server side and create function
1939 silc_server_command_join_channel internal routine to make the
1942 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * Changed silc_command_pending list to SilcDList. Also, added
1945 `ident' field to SilcServerCommandPending structure to identify
1946 the reply and to call correct callback.
1948 Added silc_server_command_pending_check function to replace the
1949 corresnponding macro. The silc_command_pending list is not
1952 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1953 to set identifier to previously allocated Command Payload. It
1954 is used to set identifier for command when resending Command
1957 * Added silc_command_payload_encode_payload to encode Command
1958 Payload buffer from SilcCommandPayload structure.
1960 * Added silc_argument_payload_encode_payload to encode Argument
1961 payload buffer from SilcArgumentPayload structure.
1963 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1965 * Changed WHOIS command to support router connection on server side.
1966 The whois request is always sent to router unless the server is
1967 standalone server. After server has received the reply from the
1968 router will it send the reply to the client.
1970 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1971 broadcast received broadcast packet. The function is used only
1972 by router. The broadcast packet is always sent to the router's
1975 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1976 render given ID to printable string, for log files for example.
1978 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Made basic router to router connections working. At least they
1981 can now connect to each other but nothing really works the way
1982 they are supposed - yet.
1984 * Added new initiator token to RouterConnection configuration
1985 file in silcd/serverconfig.[ch]. It is used to tell whether we
1986 are the initiator to the remote router or whether we'll expect
1987 the other end to connect.
1989 * Moved registering of listener task to silc_server_init, hence
1990 the server starts listenning as soon as it is run, even if it
1991 does not have connections to other routers. Let's see how well
1994 * Changed default connection retry timeouts for more suitable in
1997 * Removed cipher and such arguments from silc_idlist_add_client
1998 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1999 Added new function silc_idlist_add_data to add the keys and stuff
2002 * Added SilcIDListData structure and added it to SilcClientEntry
2003 and SilcServerEntry as their first field in the structure. This
2004 way we can explicitly cast the ID entries to the SilcIDListData
2005 structure and get common data for the entries. In past, we had
2006 to first check what type of connection it is and then cast it to
2007 correct ID entry type. Now, we can directly cast the opaque
2008 pointer to the SilcIDListData (no matter what ID entry it actually
2009 is) and get the data needed.
2011 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2014 in some circumstances even if threre were timeout tasks, though not
2015 IO tasks, but tasks anyway. Now fixed.
2017 * Defined SilcServerConnection structure to hold connection specific
2018 stuff about directly connected servers and routers. The definition
2019 is currently in silcd/server_internal.h. I thought about having
2020 a bit more important role fro this struct but for now it is used
2021 only when connecting to other server (or router actually).
2023 * Added connecting retry support in server when connecting to
2024 router(s). The retry feature implement exponential backoff
2025 algorithm. Also, added SilcServerParams structure to hold default
2026 parameters for server. For now, it include these retry settings
2027 and are hard coded. After server is moded to be as Silc Server
2028 Library this structure will be more important.
2030 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Changed client librarys channel->clients table to SilcList and
2033 changed code accordingly.
2035 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Changed client's channel table to SilcList and changed code
2038 accordingly. Also changed SilcChannelClientEntry to include back-
2039 pointer to the channel so that client entry can use that structure
2040 as list as well and we have fast cross-reference to the channel.
2041 This change dramatically decreased the complexity of channel
2042 handling with client entry and vice versa (removed one extra
2043 loop when searching for channel entry from many functions).
2045 * Changed server->sim from table to SilcDList and changed code
2048 * NAMES command can now be used from user interface. It will show
2049 the user list on the channel, neatly.
2051 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2052 Code now saves realname of the user if it becomes available.
2054 * Renamed configure.in to configure.in.pre and made ./prepare
2055 script to automatically add correct version string to
2056 configure.in which it creates from configure.in.pre.
2058 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * NAMES command reply now shows users mode with the nickname when
2063 * Moved silc_client_ch[u]mode[_char] functions from
2064 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2065 place sucks, they are utility functions and should be in some
2068 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2070 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2073 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Added TRQ (efficient deque and list library) into lib/trq. This is
2078 a very good list library that is currently used in the SILC. Defined
2079 SilcList API over the library because I didn't like the API very
2080 much. See lib/trq/silclist.h for the API and examples of how to
2081 use the API. Fixed various places in the code to use the new
2082 SilcList API. The SilcList is meant for lists that has a structure
2083 already defined as a list. It is not suitable to add just some
2084 context to the list (in TRQ, the context is the list actually).
2086 So, I defined SilcDList that can be used for the purpose where
2087 predefined list structure does not exit. This can be used as
2088 such list. Now some context just can be added to the SilcDList.
2089 Currently this list is not used in the SILC just yet, though there
2090 are a lot places where this can replace dynamically allocated
2091 tables and I will fix these places, later, to use SilcDList.
2092 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2093 and use TRQ internally).
2095 Also fixed some annoying warning messages that the original TRQ
2096 code generated. Also minor changes to TRQ's Makefile.in.
2098 * Added support for querying by Client ID to both WHOIS and
2099 IDENTIFY commands into server, as required by the protocol.
2101 * Removed method function pointers from SilcBuffer structure. They
2102 weren't used to anything and just increased the context size for
2103 no good reason. This change also made silc_buffer_alloc and
2104 silc_buffer_free functions inline functions.
2106 * Disabled command flooding detection support until it's fixed so
2107 that it accepts commands in but does not execute them more than once
2110 * Added silc_net_localhost(), to return local hostname, into
2111 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2112 that must be initialized before calling silc_client_init.
2114 * Added new function: silc_server_send_notify_on_channels to send
2115 notify messages to all channels client has joined. It is assured
2116 that the message is sent only once per client.
2118 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2119 lib/silcutil/silcutil.[ch] as silc_format function. The new
2120 function is generic and is used by server as well, not only by
2121 the logging routines.
2123 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2124 the provided version string was not acceptable. Added new function:
2125 silc_ske_check_version into lib/silcske/silcske.h. The function
2126 must be implemented by the application (client or server) and it
2127 does not reside in the SKE library. The function checks the version
2128 string remote end sent.
2130 * Added back pointers (to opaque context and to SilcSocketConnection)
2131 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2133 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2134 duplicate packet context structure.
2136 * Changed `notify' client operation to send same arguments as client
2137 receives from server except for ID's. ID's are mapped to correct
2138 ID entry and that is returned. Also, if channel entry is not sent
2139 by server but the notify is for channel the channel entry is sent
2140 to application (otherwise application doesn't know that it is for
2141 channel (library gets it from packet's Destination ID)).
2143 * Added silc_client_remove_from_channels into client library to
2144 remove a client from all channels it has joined to. Used when
2145 received SIGNOFF notify from server. Added also new function
2146 silc_client_replace_from_channels to replace old ID entry with
2147 new ID entry on all channels. Used when received NICK_CHANGE
2150 * Fixed ID Cache list handling in silc_idlist_get_client in
2151 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2152 to get (or query) client by ID.
2154 * Updated TODO list.
2156 * Added connection authentication status message defined by the
2157 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2158 support for these into the code in client and server side.
2160 * Added generic function silc_client_send_command to send any command
2161 with variable argument list. Application should use this function
2162 to send commands if the command functions provided by the library
2163 does not suite for the application's user interface needs.
2165 * Added new `failure' client operation. Application is notified about
2166 received failure packet if client is executing a protocol. In this
2167 case the protocol's execution has failed.
2169 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2170 is required by the protocol.
2172 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2173 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2176 * Added status flag to SilcSKE object to indicate realtime status
2177 of the SKE protocol.
2179 * Application receives now exactly same command reply arguments as
2180 the library receives from server. However, if ID is received the
2181 corresponding ID entry is returned to the application (eg. Client
2182 ID is mapped to correct SilcClientEntry entry and that is returned).
2183 Changed command_reply client operation due to this change.
2185 * Changed all ID's in commands and in command replys as ID Payloads.
2186 Change affected both client and server side codes.
2188 All ID's sent in SILC network (with execption of ID's in SILC
2189 Packet header) are sent in ID Payload to support variable length
2192 * Server now notifies nick changes and notifies all clients on
2193 the channels about the new nickname (about the new Client ID,
2196 * Implemented CMODE command to change channel modes. Supports all
2197 channel modes defined by the protocol specs except ban and invite
2198 lists. (Also, private channel key mode is supported but support for
2199 setting private channel key in client is missing, thus, this mode
2200 has no effect on client side (except that server requires that the
2201 client uses private channel key and normal channel traffic does not
2204 Also, invite mode works per se, but INVITE command does not work
2205 yet correctly, so you can set channel as invite only channel but
2206 inviting clients to the channel does not work (it is yet to be
2207 thought what's the best way to do it).
2209 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2210 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2211 Implemented CUMODE command to change user's mode on the channel.
2212 Supports all modes defined by the protocol specs.
2214 * Added NAMES command reply to return users modes on the channel.
2216 * Removed unnecessary and slow ciphers from lib/silccrypt.
2218 * Set SO_KEEPALIVE option to connection sockets by default.
2220 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2222 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2223 redefined the Notify Payload into protocol specs.
2225 * Added silc_id_payload_parse_id to get ID directly from raw
2228 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2231 accept searching by Client ID as well.
2233 * Added support for LEAVE and SIGNOFF notify types in client library.
2235 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2236 to parse ID Payload from raw data.
2238 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added flags parameter into silc_ske_assemble_security_properties
2241 function in lib/silcske/silcske.[ch].
2243 * Changed notify client operation to fit better for notify messages
2244 sent by server. The notify payload received from server is now
2245 passed to the application (after parsing it to SilcNotifyPayload).
2246 It is application's responsibility to retrieve the arguments
2247 from the payload and show the message the way it wants. The message
2248 sent by server is implementation specific.
2250 * Changed public keys to comply with the protocol specification.
2251 Old public keys are not supported anymore and are not compatible.
2253 * Removed nickname from Channel Payload as the latest draft removed
2254 it. The client must resolve the nickname from the NAMES command
2255 reply received when it joined the channel.
2257 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2259 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Fixed some errors in protocol specification drafts.
2263 * Created lib/silccore/silcnotify.c to implement Notify Payload
2264 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2265 generic payloads described by protocol specifications. The file
2266 includes implementations for ID Payload and Argument Payload.
2268 * Changed Command Payload implementation to use the new Argument
2269 Payload. Changed command_xxxx_payload to command_payload_xxxx
2270 to comply with SILC coding conventions.
2272 * Added suppport for Argument Payload handling in Notify Payload
2273 implementation as protocol requires it. Added the new support
2274 into server and client lib as well.
2276 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Added support for multiple nicknames on same channel. [n] is
2279 added locally to the nickname if there are more than one same
2280 nicknames on the channel.
2282 * Server now sends all nicknames that matched WHOIS request.
2283 Client also shows the list received from server.
2285 * Added TOPIC command to client side. User can now set and show
2286 current topic on channel.
2288 * Added MOTD command to client and server. Also, server sends the
2289 motd when client connects to the server.
2291 * Changed version strings to comply ISO 8601.
2293 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Fixed protocol error handling in client library. It should now
2296 cope even if the SKE fails for some reason.
2298 * Made new protocol specification drafts for submitting to IETF.
2300 * Implemented TOPIC command to server in silcd/command.c.
2302 * Added two new notify types into lib/silccore/silcnotify.h:
2303 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2304 notify nickname change and topic setting/change on a channel.
2306 * API change of command_reply operation in client library. The
2307 application gets now the status type received from server as well.
2309 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2313 * Cras fixed and optimized the packet handling even further and
2314 it should work now. Minor change to the prototype of function
2315 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2317 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Added new function into lib/silcutil/silcschedule.[ch]:
2320 silc_schedule_with_fd to select() a specified fd. The function
2321 returns after timeout expires or data arrives or goes. The
2322 function is used by packet routines to wait that all data is
2323 received from network.
2325 * Fixed data reading from network in lib/silccore/silcpacket.c.
2326 The code now assures that all data is read from the fd and then
2327 continues packet processing. This was a bug fix since the code
2328 used to drop some data in some circumstances.
2330 * Added new function into lib/silcclient/client.[ch]:
2331 silc_client_start_key_exchange to start key exchange after
2332 connection has been established to server. The code internally
2333 now uses this funtion but its main purpose was to provide it
2334 for applications that perform their own connecting. After
2335 application has created a connection it merely calls this
2336 function to start the key exchange between client and server.
2337 The library takes care of everything else after that.
2339 Updated also lib/silcclient/README to explain the usage of
2342 * Do not send to application information that connection has
2343 been established. Application gets notified it by connect
2346 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Applied cras's patch to add silc_schedule_one function. The
2349 function runs scheduler once and returns.
2351 * Fixed the scheduler after cras messed it up. The timeout
2352 handling works now as it's supposed to work.
2354 * Added into lib/silccore/ silcnotify.h to include notify
2355 message types support. Changed silc_server_send_notify*
2356 functions, in server.[ch], to support those new notify types.
2357 Added the support for the notify types into client library,
2358 as well. Added new notify client operation into ops.h in
2361 * Changed silc_server_packet_send_to_channel to send normal
2362 packets instead of just channel message packets. The function
2363 is now used to send the notify packets to channels. It is not
2364 used to send channel message packets anymore, as server never
2367 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2368 va_arg()s as it seems to require it nowadays. I guess, if SILC
2369 is compiled with older va_arg() the new code should work anyway.
2371 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Splitted core library. Core library (lib/silccore) includes
2374 now only SILC protocol specific core (and common) components.
2375 Created new utility library (lib/silcutil) that includes more
2376 generic purpose stuff. The stuff for util library was taken
2377 from the old core library. This was minor and easy split.
2379 * Created SILC Client Library (lib/silcclient) that includes
2380 implementation of the SILC client without user interface. This
2381 was major move from silc/ directory. The code has been changed
2382 so that it is transparent towards the user interface. The
2383 silc/ directory includes now the same user interface as before
2384 and it uses the new client library. Read lib/silcclient/README.
2385 Basicly, the client library performs everything else related
2386 to SILC except user interface handling. Also, configuration
2387 files are considered to be part of user interface and library
2388 does not handle them.
2390 This change also changed a lot of structures, function naming etc.
2391 Most important change was that SilcClientWindow object was
2392 renamed to SilcClientConnection in the client library. Created
2393 also new file lib/silcclient/ops.h. Also added new files
2394 silc/local_command.[ch] and silc/client_ops.[ch].
2396 All these changes were made to make it easier for user interface
2397 designers to create what ever user interface for the SILC client
2400 It is also expected that the server will be moved to lib
2401 directory as well and SILC Server Library will be created;
2402 sometimes in the future.
2404 * Removed Local commands from lib/silccore/silccommand.h as
2405 they are application specific and new client library does not
2406 handle any of those anymore.
2408 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2409 old client implementation in silc/.
2411 * Added support for callback functions in SILC_LOG_* macros.
2412 Application can now set its own callbacks that will be called
2413 instead of using the default functions that will always print
2414 the debug messages to stderr (or stdout). Also, debugging can
2415 now be disabled by setting silc_debug to FALSE and re-enabled by
2416 setting it to TRUE. Note, that logging will still work even
2417 if debugging is disabled.
2419 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2420 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2421 silc_log_reset_debug_callbacks.
2423 * To enable debugging in silc client one must give now -d
2424 option on command line.
2426 * Changed silc_schedule_init to automatically allocate task queues
2427 if they are not allocated before calling it.
2429 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Added GMP 3.1 into math library.
2433 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2436 a channel in SILC network. The packet is used by servers and
2437 routers to notify other routers that user has left a channel.
2438 This little feature was missing until now. Added the feature
2439 to protocol specification as well.
2441 Added functions: silc_server_send_remove_channel_user and
2442 silc_server_remove_channel_user into server.[ch].
2444 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2445 lib/silccore/silcpacket.h. However, they are not implemented
2448 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Fixed joining to a channel and sending channel messages
2451 between server and router. The channel message sending should
2452 now work inside a cell.
2454 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Fixed the private message sending between server and router.
2457 The private message sending should now work inside a cell.
2459 * Added silc_server_replace_id into server.[ch] to replace
2460 existing ID in the SILC network.
2462 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2463 and silc_idlist_replace_server_id into idlist.[ch] in server.
2465 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Fixed the server to server connections. Server can again now
2468 connect to router. Router to router connections probably does
2471 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Added dynamic protocol registering support. Now protocols can
2474 registered and unregistered on the fly. Patch by cras.
2476 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Added lib/contrib directory to hold routines that some platforms
2479 don't have but are needed by SILC.
2481 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2482 into lin/contrib to provide getopt() and getopt_long() for
2483 those who don't have it.
2485 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Added AWAY command to client. When away message is set and
2488 client receives a private message packet the client automatically
2489 replies to the sender with the away message.
2491 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2492 bug seemed to be the cause of recent problems when compiling
2495 * Added version detection support to SKE protocol specification
2496 and added the new changes to the SKE implementation as well.
2497 There were other minor changes in the SKE protocol as well.
2499 Many changes in lib/silcske/silcske.[ch] and in
2500 lib/silcske/payload.[ch].
2502 * Added ^U functionality, clear input line. Patch from cras.
2504 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Mainly small bugfixes on core library. Fixed some debugging
2507 logging and buffer overflow in silclog.c.
2509 * Updated config.sub and config.guess on the distribution tree.
2511 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Added command lagging support in server. Client may execute
2514 commands now only once in two seconds.
2516 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Optimized packet reception. MAC computation and checking is now
2519 also more optimized. A lot previously duplicated code is now
2520 used as generic by both client and server.
2522 * Fixed key pair generation in clientutil.c
2524 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Added into lib/silccore/silcbufutil.[ch] new function;
2527 silc_buffer_realloc.
2529 * Moved generic packet sending/encryption functions to
2530 lib/silccore/silcpacket.[ch] from client and server. Some
2531 rewriting of the functions.
2533 * Moved all generic packet reception/decryption functions to
2534 lib/silccore/silcpacket.[ch] from client and server. The
2535 packet processing is now much cleaner in both client and server.
2536 These were major changes in both client and server.
2538 * Created many common functions in server to do packet sending.
2539 Previously code were duplicated a lot, this has been removed
2542 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Rewrote major parts of the ID cache system. Don't know
2545 whether it is better now or not but at least the API is more
2548 * Major rewrite on ID cache stuff on client because of the ID
2549 cache API changes. Added idlist.c to client.
2551 * Also major rewrite on ID cache stuff on server as well.
2552 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2553 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2554 in hand, instead they are all put into the ID cache system now.
2555 All server_idlist_* routines uses ID cache now instead of
2556 traversing its own lists (those lists does not exist anymore).
2557 SilcIDList though still exists. Also, SilcXXXEntry's are
2560 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Finally made the SKE implementation compliant to the protocol
2563 specification. All mp integers are now binary encoded as
2564 opposed being HEX encoded.
2566 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2569 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2570 functions: silc_[encode/decode]_pem. Also added function
2571 silc_encode_pem_file to PEM encode with newlines ('\n') for
2574 * SILC public keys are now encoded either PEM or binary. Same
2575 option is for private keys as well. By default private keys
2576 are binary encoded and public keys PEM encoded. Silly HEX
2577 encoding were removed.
2579 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2580 function to create fingerprints.
2582 * Fixed a bug in SHA1; does not change the original data anymore.
2584 * Partly implemented INFO command on client and server side.
2585 Fixed CLEAR command. Changes to SERVER command; show current
2586 server(s) when giving command without arguments. Added
2587 VERSION command to client.
2589 * Added check to server that unregistered connections cannot
2590 execute commands (unless it is specificly allowed).
2592 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Fixed screen refresh.
2596 * Fixed channel joining bug from client. On some circumstances
2597 client tried to join to a channel it had already joined.
2599 * Added public key verification process into client's protocol.c.
2600 The client now verifies the public key from user and saves
2601 it into ~./silc/serverkeys/ directory.
2603 Added into: clientutil.[ch]: silc_client_verify_server_key.
2605 * Changed SKE protocol's silc_ske_initiator_finish function
2606 to accept callback function that verifies the received public
2607 key. Removed old silc_ske_verify_public_key function.
2609 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2612 silc_pkcs_private_key[_data]_set.
2614 * Made the password and public authentication more cleaner in
2615 server's protocol.c.
2617 * Removed historic and obsolete protocol `channel_auth' from
2618 both client and server.
2620 * Removed wrong way of sending command status messages from
2621 server to client in server's command.c. The old way violated
2622 protocol specification.
2624 Changes to silccore/silccommand.[ch]: removed
2625 silc_command_encode_status_payload -> not needed anymore,
2626 changed silc_command_encode_payload_va to accept extra
2627 argument on variable argument list. The argument type must
2628 now be provided to the function. Also, added new function:
2629 silc_command_encode_reply_payload_va which is same as
2630 normal command_encode_payload_va except command status type
2631 is provided as extra argument.
2633 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added ~./silc directory handling. The directory includes the
2636 public and private keys for the client.
2638 Added silc_client_check_silc_dir, silc_client_create_identifier
2639 and silc_client_load_keys.
2641 * Implemented SILC protocol compliant public key. Added public
2642 and private key saving to and loading from files.
2644 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2645 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2646 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2647 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2648 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2650 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2651 silc_pkcs_load_[public/private]_key.
2653 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added silc_server_get_route (route.[ch]) to get connection
2656 data for the fastest route for given ID.
2658 * Implemented INVITE command on client and server. The command
2659 were re-defined in the SILC Protocol Specification and the
2660 implementation now complies with the specification.
2662 * Implemented PING command on client and server.
2664 * Implemented NAMES command on client and server. The server side
2665 supports currently only normal server not router server yet.
2666 Some changes to NAMES definition in SILC protocol specification.
2668 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2670 * Implemented LEAVE command on client and server.
2672 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2673 again. This change was made to the protocol as well. Server
2674 should not violate the protocol specification anymore.
2676 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2679 was tested. SOCKS4 was not but should work anyway.
