1 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4 that the command may be executed only once in (about) 2 seconds.
5 The old SILC_CF_LAG flag is same but allows command bursts up
6 to five before limiting.
8 Added the support for CF_LAG and CF_LAG_STRICT flags to the
9 server code. Various commands now includes the CF_LAG_STRICT
10 flag to disallow any kind of miss-use of the command.
12 * Fixed the silc_buffer_unformat to not to allocate any data
13 if the length of the data is zero. It used to allocate the
14 length + 1. Affected file lib/silcutil/silcbuffmt.c.
16 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
18 * Changed the format of AdminConnection configuration section
19 in the server. Added username of the admin to the format.
20 Affected files silcd/serverconfig.[ch].
22 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
23 to return admin configuration data by host, username and/or
26 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Implemented WHOWAS command to the server. Added the functions:
30 silc_server_command_whowas_parse,
31 silc_server_command_whowas_send_reply,
32 silc_server_command_whowas_from_client and
33 silc_server_command_whowas_from_server
35 * Added <Client ID> argument to the WHOWAS command reply. Updated
36 the protocol specs accordingly.
38 * Implemented WHOWAS command and command_reply to the client
41 Implemented the WHOWAS printing on the user interface.
43 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Added new argument to the WHOWAS command reply, the real name.
46 It is an optional argument. Updated the protocol specs.
48 * Added SilcIDCacheDestructor callback that is registered when
49 the SilcIDCache is allocated. The callback is called when
50 an cache entry in the ID Cache expires, or is purged from the
51 cache. Added into lib/silccore/idcache.[ch].
53 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
54 to destruct the client entries when the cache entry expires.
55 Other ID Cache's in server and in the client library ignores
58 * If the ID Cache entry's `expire' field is zero then the entry
59 never expires. Added boolean `expire' argument to the
60 silc_idcache_add function in the lib/silccore/idcache.[ch].
61 If it is TRUE the default expiry value is used.
63 * Added silc_server_free_client_data_timeout that is registered
64 when client disconnects. By default for 5 minutes we preserve
65 the client entry for history - for WHOWAS command.
67 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added support to the server to enforce that commands are not
70 executed more than once in 2 seconds. If server receives
71 commands from client more frequently, timeout is registered
72 to process the commands. Affected file silcd/command.c.
73 Added new function silc_server_command_process_timeout.
75 * Changed NICK_NOTIFY handling in client library to check that
76 if the client's nickname was changed, so there is no need to
77 resolve anything from the server.
79 * Removed error printing from the WHOIS and IDENTIFY commands.
80 If error occurs then it is ignored silently in the client library.
81 The application, however, may map the received error to
82 human readable error string. The application currently maps
83 the NO_SUCH_NICKNAME error to string.
85 * Made the command status message public to the application. Moved
86 them from lib/silcclient/command_reply.c to
87 lib/silcclient/command_reply.h. The application can map the
88 received command status to the string with the
89 silc_client_command_status_message function.
91 * Added check to the server to check that client's ID is same
92 as the Source ID in the packet the client sent. They must
95 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Added dist-bzip hook to the Makefile.am to make bzip2
98 compressed distributions.
100 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Server now enforces the maximum length for the nickname and
103 the channel as protocol specification dictates. 128 bytes for
104 nickname and 256 bytes for channel name.
106 * Moved the WHOIS printing to the application. The client libary
107 does not print out the WHOIS information anymore, the application
108 must do it. Renamed silc_client_command_reply_whois_print to
109 the silc_client_command_reply_whois_save.
111 The client's idle time is also sent to the application now, and
112 the idle is shown on screen.
114 * Added silc_client_command_reply_identify_save to save the
115 received IDENTIFY entries.
117 * Do not check for channel private keys in message sending and
118 reception if the channel does not have the PRIVKEY mode set.
119 Affected file lib/silclient/client_channel.c.
121 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
124 just surfaced after chaning the JOIN procedure.
126 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Added silc_client_get_clients_by_list to get client entries
129 from Client ID list, that is returned for example by JOIN
130 and USERS command replies. The application should use this
131 function for example when JOIN command reply is received to
132 resolve the clients already on the channel (library does not
133 do that anymore as USERS command reply is not used in the JOIN
134 procedure anymore). Affected files lib/silcclient/silcapi.h and
135 lib/silcclient/idlist.c.
137 * JOIN command reply and USERS command reply returns now SilcBuffer
138 pointers instead of unsigned char pointers when returning
139 the client list and mode list.
141 * Added <Client ID> argument to the JOIN command reply, mainly
142 for the server to identify for which client the command was
143 originally sent. Updated protocol specs accordingly.
145 * Added SilcDlist private_key pointer to the SilcChannelEntry
146 in the client to support the channel private keys. Affected
147 file is lib/silcclient/idlist.h.
149 * Added SilcChannelPrivateKey argument to the function
150 silc_client_send_channel_message so that application can choose
151 to use specific private ke if it wants to. If it is not provided,
152 the normal channel key is used, unless private keys are set.
153 In this case the first (key that was added first) is used
154 as the encryption key.
156 * Implemented the support for channel private key handling.
157 Implemented the following functions:
159 silc_client_add_channel_private_key,
160 silc_client_del_channel_private_keys,
161 silc_client_del_channel_private_key,
162 silc_client_list_channel_private_keys and
163 silc_client_free_channel_private_keys
165 Affected file lib/silcclient/client_channel.c.
167 * Added the support for the private keys in the channel message
168 sending and encryption and in the message reception and
169 decryption. Affected funtions are
170 silc_client_send_channel_message and silc_client_channel_message.
172 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Added SKE's key verify callback to the client library's
175 KE protocol context. Affected files lib/silcclient/protocol.[ch].
177 * Removed the statement that server (or router) must send USERS
178 command reply when joining to the channel so that the client
179 knows who are on the channel. Instead, the client list and
180 client's mode list is now sent in the JOIN command reply to the
181 client who joined channel. This is better solution.
183 * Added function silc_server_get_users_on_channel and function
184 silc_server_save_users_on_channel to the silcd/server.[ch].
186 * Removed function silc_server_command_send_users from the
189 * Do not show topic on the client library anymore. The topic is
190 sent in the command reply notify to the application and the
191 application must show the topic now.
193 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Added client searching by nickname hash into the IDENTIFY and
196 WHOIS commands in the server as they were clearly missing from
197 them. Affected file is silcd/command.c.
199 * Fixed a bug in private message receiving in the client library.
200 The remote ID was freed and it wasn't supposed, now it is
203 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Minor fix to the channel payload; allocate the data area, as it
206 needs to be of specific length.
208 * If the key agreement port is zero then the operating
209 system will define the bound port. Affected files are
210 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
212 * Added new function silc_channel_payload_decrypt into the file
213 lib/silccore/silcchannel.[ch].
215 * Moved the channel message etc, check from silc_packet_decrypt
216 to applications. The library calls now a generic
217 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
218 when the packet is either normal or special. This was done to
219 allow more wide range of checking that was not allowed when
220 the code was in library. Now applications can do virtually any
221 checks to the packet and return to the library the decision how
222 the packet should be processed. Affected files are
223 lib/silccore/silcpacket.[ch].
225 Added silc_server_packet_decrypt_check to the server and
226 silc_client_packet_decrypt_check to the client library.
228 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
229 to send with specified source and destination information.
231 * Channel message delivery between routers was broken after the
232 channel key distribution was fixed earlier. The channel key
233 was used be to distributed to other routers as well which is not
234 allowed by the protocol. Now this is fixed and channel keys
235 really are cell specific and the channel message delivery between
236 routers comply with the protocol specification.
238 * Fixed various commands in server to check also the global list
239 for the channel entry and not just the local list. The affected
240 file silcd/command.c.
242 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Added assert()s to buffer formatting and unformatting routines
245 to assert (if --enable-debug) when error occurs. Affected
246 file: lib/silcutil/silcbuffmt.c.
248 * Changed to auto-reconnect to check whether the remote host is
249 router and register the re-connect timeout if it is. It used
250 to check that whether we are normal server, but router must do
251 auto-reconnect with another router as well. Affected file
254 * Removed the [<key len>] option from CMODE command as the cipher
255 name decides the key length, nowadays. See the defined ciphers
256 from the protocol specification.
258 * Added [<hmac>] option to the CMODE command to define the HMAC
259 for the channel. Added SILC_CMODE_HMAC channel mode.
261 * Added [<hmac>] option for the JOIN command so that user can
262 select which HMAC is used to compute the MACs of the channel
265 * Added Hmac field to the Channel Message Payload. The integrity
266 of plaintext channel messages are now protected by computing
267 MAC of the message and attaching the MAC to the payload. The
268 MAC is encrypted. Now, it is clear that this causes some
269 overhead to the size of the packet but rationale for this is that
270 now the receiver can verify whether the channel message decrypted
271 correctly and also when private keys are set for the channel the
272 receiver can decrypt the packet with several keys and check from
273 the MAC which key decrypted the message correctly.
275 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
276 lib/silccrypt/silccipher.[ch].
278 * Added silc_hash_len to return the digest length into the
279 lib/silcrypt/silchash.[ch].
281 * Rewrote parts of Silc Channel Payload interface in the
282 lib/silccore/silcchannel.[ch]. The encode function now also
283 encrypts the packet and parse function decrypts it.
285 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Fixed a minor formatting bug in the SKE's key material processing.
288 It actually might have processed the keys wrong way resulting
291 * Redefined the mandatory HMAC algorithms and added new algorithms.
292 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
293 and hmac-md5 truncated to 96 bits. The mandatory is now
294 hmac-sha1-96. Rest are optional (including the one that used
295 to be mandatory). Rationale for this is that the truncated HMAC
296 length is sufficient from security point of view and can actually
297 make the attack against the HMAC harder. Also, the truncated
298 HMAC causes less overhead to the packets. See the RFC2104 for
301 * Added new [hmac] configuration section. The SKE used to use
302 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
303 is of course wrong. The official names that must be proposed in
304 the SKE are the ones defined in the protocol specification
305 (hmac-sha1-96 for example). The user can configure any hmac
306 using any hash function configured in the [hash] section. At
307 least, the mandatory must be configured.
309 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
311 * Added HMAC list to the SKE proposal list. It has now both
312 hash algorithm list and HMAC list. This makes the protocol
313 incompatible with previous versions. The SKE now seems to work
314 the way it is supposed to work, for the first time actually.
316 * Defined plain Hash algorithms to the protocol specification.
319 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Implemented support for key agreement packets into the server.
322 Added functions silc_server_key_agreement and
323 silc_server_send_key_agreement. Other than these functions,
324 server has nothing to do with this packet.
326 * Added support for private message key packets into the server.
327 Added functions silc_server_private_message_key and
328 silc_server_send_private_message_key.
332 * Changed the silc_[client|server]_protocol_ke_set_keys to be
333 called in the protocol's final callback instead in the END
334 protocol state. This makes a little more sense and in the same
335 time in client we can use the same protocol routines for normal
336 key exchange and to key agreement packet handling as well.
338 * Added to both client's and server's KE protocol context the
339 SilcSKEKeyMaterial pointer to save the key material. We will
340 bring the key material to the protocol's final callback by doing
341 this. The final callback must free the key material.
343 * Added SKE's packet_send callback into client's KE protocol
344 context so that the caller can choose what packet sending function
345 is used. This way we can use different packet sending when
346 doing normal SKE when doing key agreement packet handling (in
347 the key agreement packet handling we do not want to encrypt
350 * Implemented the responder side of the key agreement routines
351 in the client. The client can now bind to specified port and
352 accept incoming key negotiation. The key material is passed
353 to the application after the protocol is over.
355 * Implemented the processing of incoming Key Agreement packet
356 in the client. Added function silc_client_key_agreement to
359 * Implemented the intiator side of the key agreement routines
360 in the client. The client can now initiate key agreement with
361 another remote client. The key material is passed to the
362 application after the protocol is over.
364 * Created client_keyagr.c to include all the key agreement
367 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
368 SILC_TASK_CALLBACK except that it is not static.
370 * Created client_notify.c and moved the Notify packet handling
371 from the client.[ch] into that file.
373 * Created client_prvmsg.c and moved all private message and
374 private message key routines from the client.[ch] into that file.
376 * Create client_channel.c and moved all channel message and
377 channel private key routines from the client.[ch] into that file.
379 * Changed silc_client_get_client_by_id_resolve to resolve with
380 WHOIS command instead of IDENTIFY command, in the file
381 lib/silclient/idlist.c.
383 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Implemented the SKE's responder side to the Client library.
387 * When FAILURE is received to the protocol do not trust it
388 blindly. Register a timeout to wait whether the remote closes
389 the connection as it should do it, only after that process the
390 actual failure. This was changed to both client and server.
392 * Added client_internal.h to include some of the structures
393 there instead of client.h in lib/silcclient/.
395 * Added function silc_task_unregister_by_callback to unregister
396 timeouts by the callback function.
398 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Some "Incomplete WHOIS info" errors has been appearing on the
401 log files. Took away the entry->userinfo check from WHOIS
402 reply sending. The entry->userinfo is now " " if client did not
403 provide one. I thought this was fixed earlier but something
404 is wrong still. Let's see if the error still appears.
406 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
408 * Fixed a minor bug in the login when the channel key is
409 re-generated in the server. It used to generate the key in
410 wrong order and thus caused problems in the channel traffic.
412 * Fixed a minor bug in channel key distsribution after
413 KICK command. The key was not sent to the router even though
416 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
418 * Added silc_ske_process_key_material_data as generic routine
419 to process any key material as the SILC protocol dictates. The
420 function is used by the actual SKE library but can be used by
421 applications as well. This relates to the private message keys
422 and the channel private keys since they must be processed the
423 same way the normal SILC session keys. The protocol dictates
424 this. Affected files: lib/silcske/silcske.[ch].
426 Added also silc_ske_free_key_material to free the
427 SilcSKEKeyMaterial structure.
429 * Defined silc_cipher_set_key function to set the key for
430 cipher without using the object's method function. The affected
431 files: lib/silccrypt/silccipher.[ch].
433 * Implemented silc silc_client_add_private_message_key,
434 silc_client_add_private_message_key_ske,
435 silc_client_del_private_message_key,
436 silc_client_list_private_message_keys and
437 silc_client_free_private_message_keys functions in the
440 Added functions silc_client_send_private_message_key to send
441 the Private Message Key payload and silc_client_private_message_key
442 to handle incoming Private Message Key payload.
444 * Added Cipher field to the Private Message Key payload to set
445 the cipher to be used. If ignored, the default cipher defined
446 in the SILC protocol (aes-256-cbc) is used.
448 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Removed lib/silcclient/ops.h file.
452 Redefined parts of the SILC Client Library API. Created new
453 file silcapi.h that deprecates the ops.h file and defines the
454 published Client Library API. Defined also private message key
455 API and channel private key API into the file.
457 This is the file that the application must include from the
458 SILC Client Library. Other files need not be included by
459 the application anymore.
461 * Added new key_agreement client operation callback and also
462 defined the Key Agreement library API for the application.
464 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
466 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
467 is used by clients to request key negotiation between another
468 client in the SILC network. If the negotiation is started it
469 is performed using the SKE protocol. The result of the
470 negotiation, the secret key material, can be used for example
471 as private message key.
473 Implemented the Key Agreement payload into the files
474 lib/silccore/silauth.[ch].
476 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Redefined ciphers for the SILC protocol. Added some new ciphers
479 and defined the key lengths for the algorithms. Changed the
480 code accordingly. The default key length is now 256 bits.
482 * Fixed SKE key distribution function silc_ske_process_key_material
483 when the key length is more than 128 bits. The default key
484 length in SILC is now 256 bits.
486 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
487 to indicate unsupported algorithm.
489 * Renamed rijndael.c to aes.c and all functions as well.
491 * Fixed a long standing channel key setting bug in client library.
492 Weird that it has never surfaced before.
494 * Fixed bug in channel deletion. If the entire channel is removed
495 then it must also delete the references of the channel entry
496 from the client's channel list as the client's channel entry and
497 the channel's client entry share same memory.
499 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Implemented CONNECT and SHUTDOWN commands in the client.
503 * Implemented CLOSE command to the client.
505 * Added the function silc_idlist_find_server_by_name into the
506 files silcd/idlist.[ch].
508 Added the function silc_idlist_find_server_by_conn into the
509 files silcd/idlist.[ch].
511 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * DIE command was renamed to SHUTDOWN. Updated the both code
516 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
517 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
519 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
522 * Added function silc_server_create_connection function to create
523 connection to remote router. My server implementation actually
524 does not allow router to connect to normal server (it expects
525 that normal server always initiates the connection to the router)
526 so the CONNECT command is only good for connecting to another
529 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
532 or some other client was kicked from the channel.
534 Implemented the handling of the notify type to both client
537 Implemented silc_server_send_notify_kicked to send the KICKED
538 notify. It is used to send it to the server's primary router.
540 * Implemented the KICK command into server and client.
542 * Added `query' argument to the silc_idlist_get_client function
543 to indicate whether to query the client from server or not if
546 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
547 to indicate that the client is not channel founder.
551 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Removed the rng context from SilcPacketContext structure and
554 changed that the packet routine uses the Global RNG API.
556 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Added support for quit message that client can "leave" on the
559 channel when it quits the SILC. It is ditributed inside the
560 SILC_NOTIFY_TYPE_SIGNOFF notify type.
562 Added silc_server_free_client_data that will take the
563 signoff message as argument.
565 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
567 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Updated parts of the protocol specification to keep it up
572 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
575 payloads in one packet.
577 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
578 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
579 use now the new List flag.
581 * Also deprecated the following packet types: REPLACE_ID,
582 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
584 * Added list support for Notify packet in server.
586 * Added silc_server_send_notify_channel_change to send the
587 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
588 the silc_server_send_replace_id.
590 * Added silc_server_send_notify_nick_change to send the
591 NICK_CHANGE notify type. Deprecates the function
592 silc_server_send_replace_id.
594 * Added silc_server_send_notify_join to send the JOIN notify type.
595 Deprecates the function silc_server_send_new_channel_user.
597 * Added silc_server_send_notify_leave to send LEAVE notify type.
598 Deprecates the function silc_server_send_remove_channel_user.
600 * Added silc_server_send_notify_cmode and
601 silc_server_send_notify_cumode to send CMODE and CUMODE notify
602 types. Deprecates the silc_server_send_set_mode function.
604 * Added SERVER_SIGNOFF notify type to indicate that server has
605 quit. This means that all clients on the channel from that
606 server will drop. This can be also used when netsplit happens.
608 Deprecated REMOVE_ID packet type since it is not needed anymore
611 Added silc_server_send_notify_server_signoff to send the
612 SERVER_SIGNOFF notify type. Deprecates the function
613 silc_server_send_remove_id.
615 Added also silc_server_send_notify_signoff to send the
618 * Employed the PKCS #1. It is the mandatory way to do RSA in the
619 SILC protocol from this day on. Changed the protocol
620 specification as well.
622 * Added silc_server_send_notify_topic_set to send TOPIC_SET
623 notify type. It is used between routers to notify about
624 topic changes on a channel.
626 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
629 * Partly updated the protocol specification to comply with the
630 changes now made. It is still though a bit outdated.
632 * The JOIN notify type now takes one extra argument <Channel ID>.
633 The packet used to be destined to the channel but now the
634 JOIN type may be sent as list thus it is impossible to
635 destine it to any specific channel. By adding this argument
636 it is again possible.
638 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Added CREDITS file. The CHANGES and CREDITS file will appear
641 in the distribution as well.
643 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
646 types in the server's silcd/packet_receive.c.
648 * Implemented CMODE and CUMODE to work in router environment.
650 * Fixed minor encoding and decoding buglet from the
651 lib/silccore/silcmode.c.
653 * Fixed buffer overflow from lib/silcclient/command.c in USERS
656 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
658 * Changed all SilcConfigServer* and silc_config_server* to
659 SilcServerConfig* and silc_server_config*, respectively.
662 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Associated the ID (client or server ID) to the Authentication
665 Payload to avoid any possibility of forging. Updated the
666 protocol specification and the code accordingly.
668 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * The RSA key length is now save to the RsaKey context in the
671 key generation process in lib/silccrypt/rsa.c. The key length
672 is now used to figure out the maximum size of the block allowed
673 to be encrypted/signed.
675 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
676 is equivalent to the silc_mp_mp2bin but does not allocate any
679 * Changed silc_mp_mp2bin API to take length argument. If it is
680 non-zero then the buffer is allocated that large. If zero, then
681 the size is approximated using silc_mp_sizeinbase, which however
684 * Created Global RNG API which is global RNG that application can
685 initialize. After initializing, any routine anywhere in the
686 code (including library) can use RNG without allocating a new
687 RNG object. This was done to allow this sort of use of the
688 RNG in code that has no chance to allocate RNG object. All
689 applications currently allocate this and many routines in the
690 library use this. Affected file lib/silccrypt/silcrng.[ch].
692 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
693 it to use the Global RNG API.
695 * Defined Authentication Payload into protocol specification that
696 is used during SILC session to authenticate entities. It is
697 used for example by client to authenticate itself to the server
698 to obtain server operator privileges.
700 Implemented this payload into the lib/silccore/silcauth.[ch].
701 Implemented also routines for public key based authentication
702 as the new protocol specification dictates.
704 Moved definitions of different authentication methods from
705 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
707 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
708 silc_pkcs_verify and silc_pkcs_sign_with_hash and
709 silc_pkcs_verify_with_hash functions into the file
710 lib/silccrypt/silcpkcs.[ch].
712 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * The client entry's userinfo pointer must be always valid.
715 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
716 will fail since it requires the userinfo. Now, the userinfo
717 is allocated as "" if actual userinfo does not exist. Actually,
718 it must exist and it is totally Ok to drop client connections
719 that does not announce the userinfo. However, we will make
720 this workaround for now.
722 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
723 to return the remote port by socket.
725 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
728 SILC_SERVER_PENDING_EXEC and added an new macro
729 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
730 data or when error occurs while processing the pending command.
732 Added new argument `destructor' into silc_server_command_pending
733 and to the SilcServerCommandPending object. This destructor is
734 now called after calling the pending callback or if error occurs
735 immediately. If error occurs the actual pending callback won't
736 be called at all - only the destructor. The destructor may be
737 NULL if destructor is not needed.
739 All this applies for client library code as well. Similar
740 changes were made there as well for the pending commands.
742 In the client, the application must now allocate the
743 SilcClientCommandContext with the silc_client_command_alloc
746 * Added reference counter to the SilcServerCommandContext. Added
747 function silc_server_command_alloc and silc_server_command_dup
750 Same type of functions added to the client library for the same
753 * Removed the cmd_ident from IDListData away since it is now
754 global for all connections. It is the command identifier used
755 in command sending and with pending commands. The affected file
758 * Added reference counter to the SilcSocketConnection objecet to
759 indicate the usage count of the object. The object won't be
760 freed untill the reference counter hits zero. Currently only
761 server uses this, and client ignores it. The client must be
762 set to use this too later. The affected files are
763 lib/silccore/silcsockconn.[ch]. Added also the function
764 silc_socket_dup to increase the reference counter.
766 This was mainly added because it is possible that the socket
767 is removed underneath of pending command or other async
768 operation. Now it won't be free'd and proper DISCONNECTING
769 flags, etc. can be set to avoid sending data to connection that
770 is not valid anymore.
772 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
773 the connection. After that it sets SILC_SET_DISCONNECTED.
774 It is, however, possible that the socket data is not still freed.
775 The silc_server_packet_process now checks that data is not
776 read or written to connection that is DISCONNECTED. The socket
777 get's freed when the reference counter hits zero.
779 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Changed the client operation API: channel_message operation's
782 `sender' is now the client entry of the sender, not the nickname
783 and the `channel' is the channel entry, not the channel name.
785 In the private_message operation the `sender' is now also the
786 client entry of the sender not the nickname.
788 Affected file is lib/silcclient/ops.h and all applications
789 using the client operations.
791 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Moved the calling of ops->connect() from connect_to_server_final
794 into receive_new_id functin since that is the point when the
795 client is actually allowed to send traffic to network. The
796 affected file is lib/silcclient/client.c.
798 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
801 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
802 (if needs broadcasting) instead of broadcasting the packets one
803 by one which would make a burst in the network traffic.
805 * Added `broadcast' argument to the functions in silcd/server.[ch]
806 silc_server_create_new_channel[_with_id] to indicate whether
807 to send New Channel packet to primary router.
809 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Added new function into the silcd/server.[ch] files:
812 silc_server_create_new_channel_with_id to create new channel with
813 already existing Channel ID.
815 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
816 lib/silccore/silcpacket.h. This packet is used t send list of
817 Set Mode payloads inside one packet. Server uses this to set
818 the modes for the channels and clients on those channels, that it
819 announced to the router when it connected to it. The protocol
820 specification has been updated accordingly.
822 * The silc_server_new_channel did not handle the packet coming
823 from normal server as it normally does not send that. However,
824 when it announces its channels it does send it. Implemented
825 the support for that.
827 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
828 into the file lib/silccore/id.h.
830 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Fixed memory leaks in the functions silc_idlist_del_client,
833 silc_idlist_del_channel and silc_idlist_del_server in the file
834 silcd/idlist.c. All of those leaked like a sieve.
836 * Fixed some small memory leaks in the client's function
837 silc_client_notify_by_server.
839 * Added functions into silcd/server.c: silc_server_announce_clients,
840 silc_server_announce_channels and silc_server_announce_server.
841 These functions are used by normal and router server to announce
842 to its primary router about clients, channels and servers (when
843 router) that we own. This is done after we've connected to the
846 These functions effectively implements the following packet types:
847 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
848 and SILC_PACKET_NEW_ID_LIST.
850 * Added new functions into the silcd/packet_receive.[ch]:
851 silc_server_new_id_list, silc_server_new_channel_list and
852 silc_server_new_channel_user_list to handle the incoming
853 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
855 * Added support of changing Channel ID in the function
856 silc_server_replace_id. If the server that announces a channel
857 to the router already exists in the router (with same name but
858 with different Channel ID), router is responsible to send
859 Replace ID packet to the server and force the server to change
860 the Channel ID to the one router has.
862 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
863 client that the Channel ID has been changed by the router. The
864 normal server sends this to the client. Client must start using
865 the new Channel ID as the channel's ID.
867 Implemented handling of this new type into lib/silcclient/client.c
868 into the function silc_client_notify_by_server.
870 * Added new function silc_idlist_replace_channel_id into the files
871 silcd/idlist.[ch] to replace the Channel ID.
873 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Call silc_server_command_identify_check always when processing
876 the IDENTIFY command in silcd/command.c
878 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
881 send keepalive packets. The packet can be sent by clients,
884 Added function silc_socket_set_heartbeat into the file
885 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
886 If not set, the heartbeat is not performed. The actual
887 heartbeat is implemented in the low level socket connection
888 library. However, application is responsible of actually
891 Added silc_server_send_heartbeat to send the actual heartbeat
892 packet into silcd/packet_send.[ch]. Server now performs
893 keepalive with all connections.
895 * Added silc_task_get_first function into lib/silcutil/silctask.c
896 to return the timeout task with shortest timeout. There was a bug
897 in task unregistration that caused problems. TODO has been
898 updated to include that task system must be rewritten.
900 * The client library will now resolve the client information when
901 receiving JOIN notify from server for client that we know but
902 have incomplete information.
904 * Rewrote parts of silc_server_remove_from_channels and
905 silc_server_remove_from_one_channel as they did not remove the
906 channel in some circumstances even though they should've.
908 * Encryption problem encountered in server:
910 The LEAVE command used to send the Channel Key packet to the
911 router immediately after generating it. However, the code
912 had earlier sent Remove Channel user packet but not immediately,
913 ie. it was put to queue. The order of packets in the router
914 was that Channel Key packet was first and Remove Channel User
915 packet was second, even though they were encrypted in the
916 reverse order. For this reason, MAC check failed. Now, this
917 is fixed by not sending the Channel Key packet immediately but
918 putting it to queue. However, this is more fundamental problem:
919 packets that are in queue should actually not be encrypted
920 because packets that are sent immediately gets encrypted
921 actually with wrong IV (and thus MAC check fails). So, packets
922 that are in queue should be encrypted when they are sent to
923 the wire and not when they put to the queue.
925 However, the problem is that the current system has not been
926 designed to work that way. Instead, the packet is encrypted
927 as soon as possible and left to the queue. The queue is then
928 just purged into wire. There won't be any fixes for this
929 any time soon. So, the current semantic for packet sending
932 o If you send packet to remote host and do not force the send
933 (the packet will be in queue) then all subsequent packets to the
934 same remote host must also be put to the queue. Only after the
935 queue has been purged is it safe again to force the packet
938 o If you send all packets immediately then it safe to send
939 any of subsequent packets through the queue, however, after
940 the first packet is put to queue then any subsequent packets
941 must also be put to the queue.
943 Follow these rules and everything works fine.
945 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Added new function silc_server_remove_clients_by_server to
948 remove all client entries from ID list when the server connection
949 is lost. In this case it is also important to invalidate all
950 client entires as they hold the invalid server entry. This
951 fixes fatal bug when server has lost connection and will reconnect
954 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Made some sanity checks to silc_server_daemonise like to check
957 whether the requested user and group actually exists.
959 * Added sanity check to SKE's silc_ske_responder_finish to check
960 that the public and private key actually is valid.
962 * Invalidate the client's nickname when receiving Replace ID
963 packet and the Client ID is being replaced. This means that the
964 server will query the nickname if someone needs it (client)
967 * Sort the ID Cache in client library when the ID Cache data
968 has changed (needs sorting).
970 * Do not allow for SILC client to create several connections to
971 several servers. The client does not support windows right now
972 and generating multiple connections causes weird behaviour.
974 Irssi-silc client does support windows and can handle several
975 connections without problems, see: www.irssi.org and SILC plugin.
977 * Fixed some places where client was added to the IDList. The
978 rule of thumb is following (in order to get everything right):
979 If the client is directly connected local client then the
980 `connection' argument must be set and `router' argument must be
981 NULL to silc_idlist_add_client function. If the client is not
982 directly connected client then the `router' argument must
983 bet set and the `connection' argument must be NULL to the
984 silc_idlist_add_client function.
986 * The funtion silc_server_packet_send_local_channel actually did
987 not check whether the client was locally connected or not. It
988 does that now. Fixed a bug related to LEAVE command.
990 * Fixed Remove Channel User payload parsing bug in server's
991 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
993 * The server's silc_server_save_channel_key now checks also the
994 global ID list for the channel as it might not be in the local
995 list. Fixed a bug related to LEAVE command.
997 * Is this the end of the [<unknown>] buglet that has been lurking
998 around for a long time? A little for loop fix in server's
999 silc_server_command_whois_parse that is used by both IDENTIFY
1000 and WHOIS command. At least, this was a clear bug and a cause
1001 of one type of [<unknown>] buglet.
1003 * WHOIS and IDENTIFY commands call the function
1004 silc_server_command_[whois/identify]_check function even if
1005 we are not router server.
1007 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Added --with-gmp configuration option. If set the GMP
1010 is always compiled in the SILC source tree. If not set then
1011 it is checked whether the system has the GMP3 installed. If
1012 it has then the GMP won't be compiled (the system's headers
1013 and library is used), if it doesn't have it then the GMP is
1014 compiled in the SILC source tree.
1016 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Changed RSA private exponent generation to what PKCS #1
1019 suggests. We try to find the smallest possible d by doing
1020 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1021 not security fix but optimization.
1023 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Added new config entry [Identity] to fork the server and run
1026 it as specific user and group. A patch from Bostik.
1028 * Imported Dotconf configuration library into lib/dotconf.
1029 This will be used to create the SILC configuration files later.
1030 It will appear in the distsribution after this commit.
1032 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * A big code auditing weekend happening. Auditing code for
1035 obvious mistakes, bugs and errors. Also, removing any code
1038 Removed files for being obsolete:
1040 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1041 inline in the file lib/silcutil/silcbuffer.h)
1043 o lib/silcutil/silcbufutil.c (the header has inline versions)
1045 Changed code to fix possible error conditions:
1047 o The buffer formatting routines now check that the destination
1048 buffer really has enough space to add the data. This applies for
1049 both buffer formatting and unformatting
1050 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1051 unformatting was changed to accomodate following rules:
1052 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1053 sent to the function while XXX_*STRING will not allocate or copy
1054 the data into the buffer. Instead it sets the pointer from the
1055 buffer into the pointer sent as argument (XXX_*STRING used to
1056 require that the pointer must be allocated already). This change
1057 makes this whole thing a bit more consistent and more optimized
1058 (note that the data returned in the unformatting with XXX_*STRING
1059 must not be freed now). The routines return now -1 on error.
1061 o Tried to find all code that use buffer_format and buffer_unformat
1062 and added return value checking to prevent formatting and
1063 especially unformatting errors and possible subsequent fatal
1066 o Changed ske->x and ske->KEY to mallocated pointers in
1067 lib/silcske/silcske.h. Fixed possible data and memory leak.
1069 o Added return value checking to all *_parse* functions. Fixed
1070 many memory leaks as well.
1072 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1073 so that buffer overflows would not happen. All code now also
1074 checks the return value as it can fail.
1076 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Added reconnection support to server if the normal server looses
1079 its connection to the router (for example if router is rebooted).
1080 The server performs normal reconnection strategy implemented
1081 to the server. Affected file silcd/server.c.
1083 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Added new packet type SILC_PACKET_SET_MODE that is used to
1086 distribute the information about changed modes (for clients,
1087 channels and clients channel modes) to all routers in the
1088 network. Updated the protocol specification accordingly.
1090 Added functions into silcd/packet_send.c and
1091 silcd/packet_receive.c: silc_server_send_set_mode,
1092 silc_server_set_mode.
1094 Added new files silcmode.[ch] into lib/silccore that implements
1095 the encoding and decoding of Set Mode Payload. Added new type
1096 SilcSetModePayload. Moved the definitions of different modes
1097 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1099 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Oops, a little mistake in server's connection authentication
1102 protocol. The protocol is not ended with FAILURE but with
1103 SUCCESS if the authentication is Ok. :) Affected file is
1106 * Implemented NICK_CHANGE notify handling in server in the file
1107 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1108 the local clients on the channel. After the changing nickname
1109 in router environment snhould work and the [<unknown>] nickname
1110 should appear no more.
1112 The silc_server_replace_id function that receives the Replace ID
1113 payload now sends the NICK_CHANGE notify type also in the file
1114 silcd/packet_receive.c
1116 * Changed WHOIS and IDENTIFY command to support the maximum amount
1117 of arguments defined in protocol specs (3328 arguments). This
1118 fixed a bug that caused problems when there were more than three
1121 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Added extra parameter, command identifier, to the
1124 silc_client_send_command so that explicit command identifier
1127 Changed that ID list routines uses specific command identifier
1128 when sending WHOIS/IDENTIFY requests to the server so that they
1129 can be identified when the reply comes back.
1131 Affected files lib/silcclient/command.[ch],
1132 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1134 * Added `sender' argument to silc_server_packet_send_to_channel
1135 to indicaet the sender who originally sent the packet to us
1136 that we are now re-sending. Ignored if NULL. Affected file
1137 silcd/packet_send.[ch].
1139 * Added some server statistics support in silcd/server_internal.h
1140 SilcServerStatistics structure and around the server code. Also
1141 send some nice statistics information when client is connecting
1144 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Fixed channel ID decoding in server's JOIN command reply in
1147 silcd/command_reply.c
1149 * Fixed braodcasting of replace ID payload to not to send it if
1150 we are standalone server in silcd/packet_receive.c.
1152 * Fixed all channel message sending routines to not to send
1153 packets to clients that has router set, since they are routed
1154 separately in the same function earlier. Affects file
1155 silcd/packet_send.c and all channel packet sending functions.
1157 * In USERS reply, res_argv[i] are not allocated, the table
1158 is allocated. Thus changed that free the table, not its
1161 * In server's whois_check and identify_check if the client is
1162 locally connected do not send any WHOIS commands - they are not
1165 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Fixed some minor bugs in client when sending WHOIS command. The
1168 arguments was in wrong order.
1170 * Removed statis function add_to_channel from server in
1171 silcd/command.c that was previously used with the joining but
1174 * Tested USERS command in router environment successfully with two
1175 routers, two servers and two clients.
1177 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Reorganized the USERS command and command reply in client library
1180 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1181 When the command is given by user we register a pending command
1182 callback that will reprocess the command after the reply has been
1183 received from the server. When reprocessing the packet we then
1184 display the information. Thus, the USERS information is displayed
1185 now in the command callback instead of in the command reply
1186 callback. The processing of the command is same as previously
1187 when server has sent the command reply in the JOINing process.
1189 * Added to USERS command in silcd/command_reply.c to join the client,
1190 we didn't use to know about, to the channel after we've created
1191 a client entry for it. Also, for clienet we did know already still
1192 check whether it is on the channel or not and add it if not.
1194 * Removed silc_server_command_join_notify as the function and its
1197 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Changed the client's pending command handling to the same as the
1200 server's pending command handling. It is also now possible to
1201 execute command reply functions from other command reply
1202 function as the function callbacks for commands and command
1203 replies are one and same. The pending commands are not static
1204 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1205 in client connection context. Thus, pending commands are server
1206 connection specific as it is convenient.
1208 Changed the function silc_client_command_pending and
1209 silc_client_command_pending_del and added new function
1210 silc_client_command_pending_check. Removed the
1211 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1214 * Added cmd_ident, current command identifier, to the client
1215 connection context in lib/silcclient/client.h to keep track on
1216 command identifiers used in command sending. Client's command reply
1217 function handling now supports the mandatory command identifiers.
1219 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1220 funtions in client to fully support pending command callbacks.
1222 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1223 as one of the arguments to the application in the command reply
1226 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1227 before first releasing SILC but came back. Now it is removed again
1228 and should come back nomore. The FORWARDED flag was used only
1229 by the JOINing procedure by forwarding the command packet to router.
1230 Now, the JOINing procedure has been changed to more generic (due
1231 to various router environment issues) and FORWARDED is not needed
1232 anymore for anything. The protocol specification is yet to be
1235 Now, removed silc_server_packet_forward from server and the flag
1236 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1238 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Renamed NAMES command to USERS command. The NAMES was named that
1241 due to historical reasons. Now it is renamed. Also, rewrote
1242 parts of the USERS command. The nickname list is not sent anymore
1243 by the server. Only Client ID and mode lists are sent in the USERS
1244 command. Changed this also to the protocol specification.
1246 The client now resolves the names and stuff after it receives
1247 the USERS list from the server when joining to the channel.
1249 * WHOIS and IDENTIFY commands has been changed to support multiple
1250 Client ID's per command. One can now search for multiple users
1251 in the network by sending only one WHOIS or IDENTIFY command.
1252 Changed the code and the protocol specifications.
1254 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1255 uses silc_server_command_whois_parse to parse the request. */
1257 * If normal server, do not parse the WHOIS and IDENTIFY requests
1258 before sending it to the router. Saves some time.
1260 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Fixed JOIN command on client library. Wrong number of arguments
1263 used to crash the client.
1265 * Added silc_server_channel_has_global function to check whether
1266 channel has global users or not.
1268 * Added silc_server_channel_has_local function to check whether channel
1269 has locally connected clients on the channel.
1271 * The silc_server_remove_from_one_channel now checks whether the
1272 channel has global users or not after given client was removed from
1273 the channel. It also checks whether the channel has local clients
1274 on the channel anymore. If it does not have then the channel entry
1275 is removed as it is not needed anymore.
1277 * The silc_server_notify now checks on JOIN notify whether the joining
1278 client is one of locally connected or global. If it is global then
1279 the channel has now global users on the channel and that is marked
1280 to the channel entry. Also, it now saves the global client to
1281 global list who is joining and JOINs it to the channel. This is
1282 for normal server, that is.
1284 Changed silc_server_send_notify_on_channel,
1285 silc_server_packet_relay_to_channel and
1286 silc_server_packet_send_to_channel check if we are normal server
1287 and client has router set (ie. global client) do not send the
1288 message to that client, as it is already routed to our router.
1290 * Implemented LEAVE notify type handling in silc_server_notify
1293 * Tested LEAVE command in router environment successfully. Tested
1294 with two routers, two servers and two clients.
1298 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1300 * Implemented SIGNOFF notify type handling in silc_server_notify
1303 * silc_server_remove_id now removes the client entry from all channels
1304 it has joined and thusly sends SIGNOFF notify type.
1306 * Rewrote the NAMES list generation in server by removing two excess
1307 loops. The lists are created now inside one loop.
1309 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * silc_server_remove_channel_user checks now also global list
1312 for channel and client.
1314 * silc_server_new_channel_user checks now both local and global
1315 list for channel and client. Fixed a bug in client id decoding.
1316 Used to decode wrong buffer.
1318 * silc_server_channel_message checks now both local and global
1319 list for channel entry.
1321 * Tested channel joining (hence JOIN) in router environment
1322 successfully. Tested with two routers, two servers and two
1325 * Tested channel message sending in router environment successfully.
1327 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Added silc_server_save_channel_key into server.[ch] to save the
1330 received channel key in Channel Key payload processing. It is
1331 also used in JOIN command reply handling.
1333 Equivalent function silc_client_save_channel_key added into
1334 client.[ch] into client library.
1336 * Changed JOIN command reply to send information whether the channel
1337 was created or not (is existing already) and the channel key
1338 payload. Changed protocol specs accordingly.
1340 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1341 the request was sent by ID and not by nickname. Crashed on
1344 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1347 now correctly save the received data.
1349 * silc_server_free_sock_user_data now notifies routers in the
1350 network about entities leaving the network.
1352 At the same time implemented functions silc_server_remove_id
1353 and silc_server_send_remove_id to receive and send REMOVE_ID
1354 packets. The packet is used to notify routers in the network
1355 about leaving entities. The ID removed will become invalid in
1358 * Added function silc_idlist_del_server into server. Removes and
1359 free's server entry from ID list.
1361 * silc_server_private_message function now checks, if we are router,
1362 that the destination ID really is valid ID, naturally.
1364 * In router when NEW_ID packet is received (for new client) the
1365 hash of the Client ID is saved in the ID Cache but the
1366 client->nickname is set to NULL, instead of putting the hash
1369 IDENTIFY command now also checks that client->nickname must be
1370 valid. If it is not if will request the data from the server who
1371 owns the client. Added new function
1372 silc_server_command_identify_check.
1374 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1375 to set the command to already allocated Command Payload.
1377 * Tested private message sending in router environment with two
1378 routers, two servers and two clients. Fixed minor bugs and now
1381 * Fixed segfault from client's NAMES command. Used to crash if
1384 * Forwarded packets must not be routed even if it is not destined
1385 to the receiver. Changed server code comply with this.
1387 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Added `require_reverse_mapping' boolean value to ServerParams
1390 structure. If TRUE (not default) the server will require that
1391 the connecting host has fully qualified domain name.
1393 If the reverse mapping is not required and hostname could not be
1394 found the IP address is used as hostname.
1396 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Implemented version string checking to both client and server.
1399 The check is incomplete currently due to the abnormal version
1400 strings used in development version of SILC.
1402 * Changed all command functions in server to use the new
1405 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Changed char *data to unsigned char *data in ID Cache system to
1408 support binary data as ID Cache data. Changed code to support
1409 binary data in lib/silccore/idcache.c.
1411 * Renamed silc_server_packet_relay_command_reply to
1412 silc_server_command_reply as it is normal packet receiving
1413 function. Rewrote the function to accept command replys for
1414 servers and not only for clients.
1416 * Mark remote router always as registered server if we are connecting
1417 to it. Otherwise, commands sent by the router to us are ignored.
1419 * All ID List find routines now returns the ID Cache Entry pointer
1420 as well if requested.
1422 * WHOIS command works now in router environment, tested with two
1423 routers, two servers and two clients.
1425 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1426 in router environment (as it is almost equivalent to WHOIS) but
1427 hasn't been tested thoroughly. Added new functions:
1429 silc_server_command_identify_parse
1430 silc_server_command_identify_send_reply
1431 silc_server_command_identify_from_client
1432 silc_server_command_identify_from_server
1434 * Disabled route cache adding because adding two different ID's with
1435 same IP replaces the old cache entry thus giving wrong route.
1436 The entry->router->connection is always the fastest route anyway
1437 so route cache may not be needed. Of course, new routes maybe
1438 established after receiving the ID when the entry->router->connection
1439 might not be anymore the most optimal.
1441 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Add route cache for received ID for fast routing.
1445 * Added silc_server_packet_route to route received packet on router
1446 that is not destined to us.
1448 * Renamed silc_server_get_route to silc_server_route_get.
1450 * Added id_string and id_string_len fields into SilcServer to
1451 include encoded ServerID for fast comparing without excess
1452 encoding of the ID's.
1454 * Cleaned up WHOIS command on server side. Added following static
1457 silc_server_command_whois_parse
1458 silc_server_command_whois_check
1459 silc_server_command_whois_send_reply
1460 silc_server_command_whois_from_client
1461 silc_server_command_whois_from_server
1463 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1464 arguments in command replies. All command functions should be
1465 updated to use this macro.
1467 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Minor typo fixes on command reply handling on server.
1471 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Added silc_server_command_add_to_channel internal routine to add
1474 the client to the channel after router has created the channel and
1475 sent command reply to the server.
1477 * Added generic silc_server_send_command to send any command from
1480 * Use static buffer with ID rendering instead of duplicating data.
1482 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Fixed a channel user mode bug when joining to a channel server gave
1485 everybody channel founder rights, oops.
1487 * We mark ourselves as the router of the incoming server connection
1488 if we are router ourselves. This way we can check in some packet
1489 sending functions whether it is locally connected server. For
1490 incoming router connections we put NULL.
1492 * For router sending packets locally means now always sending the
1493 packet cell wide; to local clients and local servers. For normal
1494 server sending packet locally means sending it to only local
1497 * Fixed the JOIN command to really work in router environment. If the
1498 channel is created it is always created by the router. Router is
1499 also responsible of making the initial joining to the channel,
1500 sending JOIN notify to the sending server and distributing
1501 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1502 does not exist server doesn't do anything else but forward the
1503 command to the router which performs everything.
1505 * Added silc_server_send_channel_key function to send the Channel Key
1508 * Added silc_server_create_channel_key to create new channel key. The
1509 channel key is now re-generated everytime someone joins or leaves
1510 a channel, as protocol dictates. Note: channel->key_len is the
1513 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1516 packet_receive.[ch] to separate packet sending and receiving
1517 routines. The server.[ch] now includes everything else including
1518 actual packet processing (writing and reading data) and other
1521 Renamed silc_server_private_message_send_internal to
1522 silc_server_send_private_message. The routine is still though
1523 used only to relay private messages as server does not send
1524 private messages itself.
1526 Renamed silc_server_new_channel to silc_server_create_new_channel
1527 and added new function sicl_server_new_channel that handles the
1528 incoming New Channel packet. Added also new sending function
1529 silc_server_send_new_channel to send New Channel Payload.
1531 * Added new function silc_server_notify to process incoming notify
1532 packet to the server/router. Server may then relay the notify
1533 to clients if needed.
1535 * Added new function silc_server_new_channel_user to process incoming
1536 New Channel User packet. Router will redistribute the packet and
1537 send JOIN notify to its local clients and locally connected servers
1538 if needed. Normal server will send JOIN notify to its local client
1539 on same channel when received this packet. Added also corresponding
1540 sending function silc_server_send_new_channel_user to sent the
1543 * Added boolean route argument to send_notif_to_channel and
1544 packet_send_to_channel functions to attempt to route the packet
1545 if it is TRUE and send only locally if it is FALSE.
1547 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1549 * silc_server_replace_id now broadcasts the received replace ID
1550 packet if it is not broadcast packet already. The router must
1551 broadcast to inform other routers about changed ID.
1553 * Added backpointer to server's router into SilcServer context in
1554 silcd/server_internal.h.
1556 * Fixed silc_server_packet_broadcast to send correct broadcast
1559 * The channel key is now distributed to the local client as soon
1560 as it is received from the router (in router environment) so that
1561 no other packet may be sent for the channel until client has
1564 * silc_server_remove_channel_user now broadcasts the received
1565 Remove Channel User packet if it is not broadcast packet already.
1566 The router must broadcast to inform other routers about removed
1569 * Added users field into SilcPacketContext that is a reference count
1570 of the context. One can increase the reference count by calling
1571 silc_packet_context_dup which is now changed to just increase the
1572 reference count instead of duplicating the data. The reference
1573 count is decresed by calling silc_packet_context_free that will
1574 free the data after the reference count hits zero.
1576 For now on the packet context and everything allocated into it
1577 (including the raw packet from network) must be freed by calling
1578 the new silc_packet_context_free function. Added also new function
1579 silc_packet_context_alloc that must be used now to allocate the
1580 context. This also means that if a routine is asynchronous from
1581 silc_[client/server]_packet_parse_type the packet context must
1582 be duplicated by calling silc_packet_context_dup. Otherwise it
1583 gets free'd after silc_[client/server]_packet_parse_type returns.
1584 Also, one must remember that if packet is duplicated then its
1585 reference count must be decresed by calling the free function as
1586 many times as it was duplicated.
1588 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1589 from both client and server.
1591 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Made joining to a channel working in router environment.
1595 * Cleaned up JOIN command on server side and create function
1596 silc_server_command_join_channel internal routine to make the
1599 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Changed silc_command_pending list to SilcDList. Also, added
1602 `ident' field to SilcServerCommandPending structure to identify
1603 the reply and to call correct callback.
1605 Added silc_server_command_pending_check function to replace the
1606 corresnponding macro. The silc_command_pending list is not
1609 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1610 to set identifier to previously allocated Command Payload. It
1611 is used to set identifier for command when resending Command
1614 * Added silc_command_payload_encode_payload to encode Command
1615 Payload buffer from SilcCommandPayload structure.
1617 * Added silc_argument_payload_encode_payload to encode Argument
1618 payload buffer from SilcArgumentPayload structure.
1620 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Changed WHOIS command to support router connection on server side.
1623 The whois request is always sent to router unless the server is
1624 standalone server. After server has received the reply from the
1625 router will it send the reply to the client.
1627 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1628 broadcast received broadcast packet. The function is used only
1629 by router. The broadcast packet is always sent to the router's
1632 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1633 render given ID to printable string, for log files for example.
1635 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Made basic router to router connections working. At least they
1638 can now connect to each other but nothing really works the way
1639 they are supposed - yet.
1641 * Added new initiator token to RouterConnection configuration
1642 file in silcd/serverconfig.[ch]. It is used to tell whether we
1643 are the initiator to the remote router or whether we'll expect
1644 the other end to connect.
1646 * Moved registering of listener task to silc_server_init, hence
1647 the server starts listenning as soon as it is run, even if it
1648 does not have connections to other routers. Let's see how well
1651 * Changed default connection retry timeouts for more suitable in
1654 * Removed cipher and such arguments from silc_idlist_add_client
1655 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1656 Added new function silc_idlist_add_data to add the keys and stuff
1659 * Added SilcIDListData structure and added it to SilcClientEntry
1660 and SilcServerEntry as their first field in the structure. This
1661 way we can explicitly cast the ID entries to the SilcIDListData
1662 structure and get common data for the entries. In past, we had
1663 to first check what type of connection it is and then cast it to
1664 correct ID entry type. Now, we can directly cast the opaque
1665 pointer to the SilcIDListData (no matter what ID entry it actually
1666 is) and get the data needed.
1668 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1671 in some circumstances even if threre were timeout tasks, though not
1672 IO tasks, but tasks anyway. Now fixed.
1674 * Defined SilcServerConnection structure to hold connection specific
1675 stuff about directly connected servers and routers. The definition
1676 is currently in silcd/server_internal.h. I thought about having
1677 a bit more important role fro this struct but for now it is used
1678 only when connecting to other server (or router actually).
1680 * Added connecting retry support in server when connecting to
1681 router(s). The retry feature implement exponential backoff
1682 algorithm. Also, added SilcServerParams structure to hold default
1683 parameters for server. For now, it include these retry settings
1684 and are hard coded. After server is moded to be as Silc Server
1685 Library this structure will be more important.
1687 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Changed client librarys channel->clients table to SilcList and
1690 changed code accordingly.
1692 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Changed client's channel table to SilcList and changed code
1695 accordingly. Also changed SilcChannelClientEntry to include back-
1696 pointer to the channel so that client entry can use that structure
1697 as list as well and we have fast cross-reference to the channel.
1698 This change dramatically decreased the complexity of channel
1699 handling with client entry and vice versa (removed one extra
1700 loop when searching for channel entry from many functions).
1702 * Changed server->sim from table to SilcDList and changed code
1705 * NAMES command can now be used from user interface. It will show
1706 the user list on the channel, neatly.
1708 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1709 Code now saves realname of the user if it becomes available.
1711 * Renamed configure.in to configure.in.pre and made ./prepare
1712 script to automatically add correct version string to
1713 configure.in which it creates from configure.in.pre.
1715 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1717 * NAMES command reply now shows users mode with the nickname when
1720 * Moved silc_client_ch[u]mode[_char] functions from
1721 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1722 place sucks, they are utility functions and should be in some
1725 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1727 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1730 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Added TRQ (efficient deque and list library) into lib/trq. This is
1735 a very good list library that is currently used in the SILC. Defined
1736 SilcList API over the library because I didn't like the API very
1737 much. See lib/trq/silclist.h for the API and examples of how to
1738 use the API. Fixed various places in the code to use the new
1739 SilcList API. The SilcList is meant for lists that has a structure
1740 already defined as a list. It is not suitable to add just some
1741 context to the list (in TRQ, the context is the list actually).
1743 So, I defined SilcDList that can be used for the purpose where
1744 predefined list structure does not exit. This can be used as
1745 such list. Now some context just can be added to the SilcDList.
1746 Currently this list is not used in the SILC just yet, though there
1747 are a lot places where this can replace dynamically allocated
1748 tables and I will fix these places, later, to use SilcDList.
1749 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1750 and use TRQ internally).
1752 Also fixed some annoying warning messages that the original TRQ
1753 code generated. Also minor changes to TRQ's Makefile.in.
1755 * Added support for querying by Client ID to both WHOIS and
1756 IDENTIFY commands into server, as required by the protocol.
1758 * Removed method function pointers from SilcBuffer structure. They
1759 weren't used to anything and just increased the context size for
1760 no good reason. This change also made silc_buffer_alloc and
1761 silc_buffer_free functions inline functions.
1763 * Disabled command flooding detection support until it's fixed so
1764 that it accepts commands in but does not execute them more than once
1767 * Added silc_net_localhost(), to return local hostname, into
1768 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1769 that must be initialized before calling silc_client_init.
1771 * Added new function: silc_server_send_notify_on_channels to send
1772 notify messages to all channels client has joined. It is assured
1773 that the message is sent only once per client.
1775 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1776 lib/silcutil/silcutil.[ch] as silc_format function. The new
1777 function is generic and is used by server as well, not only by
1778 the logging routines.
1780 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1781 the provided version string was not acceptable. Added new function:
1782 silc_ske_check_version into lib/silcske/silcske.h. The function
1783 must be implemented by the application (client or server) and it
1784 does not reside in the SKE library. The function checks the version
1785 string remote end sent.
1787 * Added back pointers (to opaque context and to SilcSocketConnection)
1788 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1790 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1791 duplicate packet context structure.
1793 * Changed `notify' client operation to send same arguments as client
1794 receives from server except for ID's. ID's are mapped to correct
1795 ID entry and that is returned. Also, if channel entry is not sent
1796 by server but the notify is for channel the channel entry is sent
1797 to application (otherwise application doesn't know that it is for
1798 channel (library gets it from packet's Destination ID)).
1800 * Added silc_client_remove_from_channels into client library to
1801 remove a client from all channels it has joined to. Used when
1802 received SIGNOFF notify from server. Added also new function
1803 silc_client_replace_from_channels to replace old ID entry with
1804 new ID entry on all channels. Used when received NICK_CHANGE
1807 * Fixed ID Cache list handling in silc_idlist_get_client in
1808 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1809 to get (or query) client by ID.
1811 * Updated TODO list.
1813 * Added connection authentication status message defined by the
1814 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1815 support for these into the code in client and server side.
1817 * Added generic function silc_client_send_command to send any command
1818 with variable argument list. Application should use this function
1819 to send commands if the command functions provided by the library
1820 does not suite for the application's user interface needs.
1822 * Added new `failure' client operation. Application is notified about
1823 received failure packet if client is executing a protocol. In this
1824 case the protocol's execution has failed.
1826 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1827 is required by the protocol.
1829 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1830 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1833 * Added status flag to SilcSKE object to indicate realtime status
1834 of the SKE protocol.
1836 * Application receives now exactly same command reply arguments as
1837 the library receives from server. However, if ID is received the
1838 corresponding ID entry is returned to the application (eg. Client
1839 ID is mapped to correct SilcClientEntry entry and that is returned).
1840 Changed command_reply client operation due to this change.
1842 * Changed all ID's in commands and in command replys as ID Payloads.
1843 Change affected both client and server side codes.
1845 All ID's sent in SILC network (with execption of ID's in SILC
1846 Packet header) are sent in ID Payload to support variable length
1849 * Server now notifies nick changes and notifies all clients on
1850 the channels about the new nickname (about the new Client ID,
1853 * Implemented CMODE command to change channel modes. Supports all
1854 channel modes defined by the protocol specs except ban and invite
1855 lists. (Also, private channel key mode is supported but support for
1856 setting private channel key in client is missing, thus, this mode
1857 has no effect on client side (except that server requires that the
1858 client uses private channel key and normal channel traffic does not
1861 Also, invite mode works per se, but INVITE command does not work
1862 yet correctly, so you can set channel as invite only channel but
1863 inviting clients to the channel does not work (it is yet to be
1864 thought what's the best way to do it).
1866 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1867 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1868 Implemented CUMODE command to change user's mode on the channel.
1869 Supports all modes defined by the protocol specs.
1871 * Added NAMES command reply to return users modes on the channel.
1873 * Removed unnecessary and slow ciphers from lib/silccrypt.
1875 * Set SO_KEEPALIVE option to connection sockets by default.
1877 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1879 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1880 redefined the Notify Payload into protocol specs.
1882 * Added silc_id_payload_parse_id to get ID directly from raw
1885 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1888 accept searching by Client ID as well.
1890 * Added support for LEAVE and SIGNOFF notify types in client library.
1892 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1893 to parse ID Payload from raw data.
1895 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added flags parameter into silc_ske_assemble_security_properties
1898 function in lib/silcske/silcske.[ch].
1900 * Changed notify client operation to fit better for notify messages
1901 sent by server. The notify payload received from server is now
1902 passed to the application (after parsing it to SilcNotifyPayload).
1903 It is application's responsibility to retrieve the arguments
1904 from the payload and show the message the way it wants. The message
1905 sent by server is implementation specific.
1907 * Changed public keys to comply with the protocol specification.
1908 Old public keys are not supported anymore and are not compatible.
1910 * Removed nickname from Channel Payload as the latest draft removed
1911 it. The client must resolve the nickname from the NAMES command
1912 reply received when it joined the channel.
1914 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1916 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Fixed some errors in protocol specification drafts.
1920 * Created lib/silccore/silcnotify.c to implement Notify Payload
1921 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1922 generic payloads described by protocol specifications. The file
1923 includes implementations for ID Payload and Argument Payload.
1925 * Changed Command Payload implementation to use the new Argument
1926 Payload. Changed command_xxxx_payload to command_payload_xxxx
1927 to comply with SILC coding conventions.
1929 * Added suppport for Argument Payload handling in Notify Payload
1930 implementation as protocol requires it. Added the new support
1931 into server and client lib as well.
1933 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Added support for multiple nicknames on same channel. [n] is
1936 added locally to the nickname if there are more than one same
1937 nicknames on the channel.
1939 * Server now sends all nicknames that matched WHOIS request.
1940 Client also shows the list received from server.
1942 * Added TOPIC command to client side. User can now set and show
1943 current topic on channel.
1945 * Added MOTD command to client and server. Also, server sends the
1946 motd when client connects to the server.
1948 * Changed version strings to comply ISO 8601.
1950 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Fixed protocol error handling in client library. It should now
1953 cope even if the SKE fails for some reason.
1955 * Made new protocol specification drafts for submitting to IETF.
1957 * Implemented TOPIC command to server in silcd/command.c.
1959 * Added two new notify types into lib/silccore/silcnotify.h:
1960 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1961 notify nickname change and topic setting/change on a channel.
1963 * API change of command_reply operation in client library. The
1964 application gets now the status type received from server as well.
1966 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1970 * Cras fixed and optimized the packet handling even further and
1971 it should work now. Minor change to the prototype of function
1972 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1974 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Added new function into lib/silcutil/silcschedule.[ch]:
1977 silc_schedule_with_fd to select() a specified fd. The function
1978 returns after timeout expires or data arrives or goes. The
1979 function is used by packet routines to wait that all data is
1980 received from network.
1982 * Fixed data reading from network in lib/silccore/silcpacket.c.
1983 The code now assures that all data is read from the fd and then
1984 continues packet processing. This was a bug fix since the code
1985 used to drop some data in some circumstances.
1987 * Added new function into lib/silcclient/client.[ch]:
1988 silc_client_start_key_exchange to start key exchange after
1989 connection has been established to server. The code internally
1990 now uses this funtion but its main purpose was to provide it
1991 for applications that perform their own connecting. After
1992 application has created a connection it merely calls this
1993 function to start the key exchange between client and server.
1994 The library takes care of everything else after that.
1996 Updated also lib/silcclient/README to explain the usage of
1999 * Do not send to application information that connection has
2000 been established. Application gets notified it by connect
2003 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Applied cras's patch to add silc_schedule_one function. The
2006 function runs scheduler once and returns.
2008 * Fixed the scheduler after cras messed it up. The timeout
2009 handling works now as it's supposed to work.
2011 * Added into lib/silccore/ silcnotify.h to include notify
2012 message types support. Changed silc_server_send_notify*
2013 functions, in server.[ch], to support those new notify types.
2014 Added the support for the notify types into client library,
2015 as well. Added new notify client operation into ops.h in
2018 * Changed silc_server_packet_send_to_channel to send normal
2019 packets instead of just channel message packets. The function
2020 is now used to send the notify packets to channels. It is not
2021 used to send channel message packets anymore, as server never
2024 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2025 va_arg()s as it seems to require it nowadays. I guess, if SILC
2026 is compiled with older va_arg() the new code should work anyway.
2028 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Splitted core library. Core library (lib/silccore) includes
2031 now only SILC protocol specific core (and common) components.
2032 Created new utility library (lib/silcutil) that includes more
2033 generic purpose stuff. The stuff for util library was taken
2034 from the old core library. This was minor and easy split.
2036 * Created SILC Client Library (lib/silcclient) that includes
2037 implementation of the SILC client without user interface. This
2038 was major move from silc/ directory. The code has been changed
2039 so that it is transparent towards the user interface. The
2040 silc/ directory includes now the same user interface as before
2041 and it uses the new client library. Read lib/silcclient/README.
2042 Basicly, the client library performs everything else related
2043 to SILC except user interface handling. Also, configuration
2044 files are considered to be part of user interface and library
2045 does not handle them.
2047 This change also changed a lot of structures, function naming etc.
2048 Most important change was that SilcClientWindow object was
2049 renamed to SilcClientConnection in the client library. Created
2050 also new file lib/silcclient/ops.h. Also added new files
2051 silc/local_command.[ch] and silc/client_ops.[ch].
2053 All these changes were made to make it easier for user interface
2054 designers to create what ever user interface for the SILC client
2057 It is also expected that the server will be moved to lib
2058 directory as well and SILC Server Library will be created;
2059 sometimes in the future.
2061 * Removed Local commands from lib/silccore/silccommand.h as
2062 they are application specific and new client library does not
2063 handle any of those anymore.
2065 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2066 old client implementation in silc/.
2068 * Added support for callback functions in SILC_LOG_* macros.
2069 Application can now set its own callbacks that will be called
2070 instead of using the default functions that will always print
2071 the debug messages to stderr (or stdout). Also, debugging can
2072 now be disabled by setting silc_debug to FALSE and re-enabled by
2073 setting it to TRUE. Note, that logging will still work even
2074 if debugging is disabled.
2076 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2077 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2078 silc_log_reset_debug_callbacks.
2080 * To enable debugging in silc client one must give now -d
2081 option on command line.
2083 * Changed silc_schedule_init to automatically allocate task queues
2084 if they are not allocated before calling it.
2086 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Added GMP 3.1 into math library.
2090 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2093 a channel in SILC network. The packet is used by servers and
2094 routers to notify other routers that user has left a channel.
2095 This little feature was missing until now. Added the feature
2096 to protocol specification as well.
2098 Added functions: silc_server_send_remove_channel_user and
2099 silc_server_remove_channel_user into server.[ch].
2101 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2102 lib/silccore/silcpacket.h. However, they are not implemented
2105 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Fixed joining to a channel and sending channel messages
2108 between server and router. The channel message sending should
2109 now work inside a cell.
2111 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Fixed the private message sending between server and router.
2114 The private message sending should now work inside a cell.
2116 * Added silc_server_replace_id into server.[ch] to replace
2117 existing ID in the SILC network.
2119 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2120 and silc_idlist_replace_server_id into idlist.[ch] in server.
2122 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Fixed the server to server connections. Server can again now
2125 connect to router. Router to router connections probably does
2128 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Added dynamic protocol registering support. Now protocols can
2131 registered and unregistered on the fly. Patch by cras.
2133 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Added lib/contrib directory to hold routines that some platforms
2136 don't have but are needed by SILC.
2138 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2139 into lin/contrib to provide getopt() and getopt_long() for
2140 those who don't have it.
2142 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Added AWAY command to client. When away message is set and
2145 client receives a private message packet the client automatically
2146 replies to the sender with the away message.
2148 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2149 bug seemed to be the cause of recent problems when compiling
2152 * Added version detection support to SKE protocol specification
2153 and added the new changes to the SKE implementation as well.
2154 There were other minor changes in the SKE protocol as well.
2156 Many changes in lib/silcske/silcske.[ch] and in
2157 lib/silcske/payload.[ch].
2159 * Added ^U functionality, clear input line. Patch from cras.
2161 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Mainly small bugfixes on core library. Fixed some debugging
2164 logging and buffer overflow in silclog.c.
2166 * Updated config.sub and config.guess on the distribution tree.
2168 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Added command lagging support in server. Client may execute
2171 commands now only once in two seconds.
2173 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Optimized packet reception. MAC computation and checking is now
2176 also more optimized. A lot previously duplicated code is now
2177 used as generic by both client and server.
2179 * Fixed key pair generation in clientutil.c
2181 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Added into lib/silccore/silcbufutil.[ch] new function;
2184 silc_buffer_realloc.
2186 * Moved generic packet sending/encryption functions to
2187 lib/silccore/silcpacket.[ch] from client and server. Some
2188 rewriting of the functions.
2190 * Moved all generic packet reception/decryption functions to
2191 lib/silccore/silcpacket.[ch] from client and server. The
2192 packet processing is now much cleaner in both client and server.
2193 These were major changes in both client and server.
2195 * Created many common functions in server to do packet sending.
2196 Previously code were duplicated a lot, this has been removed
2199 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Rewrote major parts of the ID cache system. Don't know
2202 whether it is better now or not but at least the API is more
2205 * Major rewrite on ID cache stuff on client because of the ID
2206 cache API changes. Added idlist.c to client.
2208 * Also major rewrite on ID cache stuff on server as well.
2209 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2210 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2211 in hand, instead they are all put into the ID cache system now.
2212 All server_idlist_* routines uses ID cache now instead of
2213 traversing its own lists (those lists does not exist anymore).
2214 SilcIDList though still exists. Also, SilcXXXEntry's are
2217 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Finally made the SKE implementation compliant to the protocol
2220 specification. All mp integers are now binary encoded as
2221 opposed being HEX encoded.
2223 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2226 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2227 functions: silc_[encode/decode]_pem. Also added function
2228 silc_encode_pem_file to PEM encode with newlines ('\n') for
2231 * SILC public keys are now encoded either PEM or binary. Same
2232 option is for private keys as well. By default private keys
2233 are binary encoded and public keys PEM encoded. Silly HEX
2234 encoding were removed.
2236 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2237 function to create fingerprints.
2239 * Fixed a bug in SHA1; does not change the original data anymore.
2241 * Partly implemented INFO command on client and server side.
2242 Fixed CLEAR command. Changes to SERVER command; show current
2243 server(s) when giving command without arguments. Added
2244 VERSION command to client.
2246 * Added check to server that unregistered connections cannot
2247 execute commands (unless it is specificly allowed).
2249 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Fixed screen refresh.
2253 * Fixed channel joining bug from client. On some circumstances
2254 client tried to join to a channel it had already joined.
2256 * Added public key verification process into client's protocol.c.
2257 The client now verifies the public key from user and saves
2258 it into ~./silc/serverkeys/ directory.
2260 Added into: clientutil.[ch]: silc_client_verify_server_key.
2262 * Changed SKE protocol's silc_ske_initiator_finish function
2263 to accept callback function that verifies the received public
2264 key. Removed old silc_ske_verify_public_key function.
2266 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2269 silc_pkcs_private_key[_data]_set.
2271 * Made the password and public authentication more cleaner in
2272 server's protocol.c.
2274 * Removed historic and obsolete protocol `channel_auth' from
2275 both client and server.
2277 * Removed wrong way of sending command status messages from
2278 server to client in server's command.c. The old way violated
2279 protocol specification.
2281 Changes to silccore/silccommand.[ch]: removed
2282 silc_command_encode_status_payload -> not needed anymore,
2283 changed silc_command_encode_payload_va to accept extra
2284 argument on variable argument list. The argument type must
2285 now be provided to the function. Also, added new function:
2286 silc_command_encode_reply_payload_va which is same as
2287 normal command_encode_payload_va except command status type
2288 is provided as extra argument.
2290 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Added ~./silc directory handling. The directory includes the
2293 public and private keys for the client.
2295 Added silc_client_check_silc_dir, silc_client_create_identifier
2296 and silc_client_load_keys.
2298 * Implemented SILC protocol compliant public key. Added public
2299 and private key saving to and loading from files.
2301 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2302 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2303 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2304 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2305 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2307 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2308 silc_pkcs_load_[public/private]_key.
2310 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Added silc_server_get_route (route.[ch]) to get connection
2313 data for the fastest route for given ID.
2315 * Implemented INVITE command on client and server. The command
2316 were re-defined in the SILC Protocol Specification and the
2317 implementation now complies with the specification.
2319 * Implemented PING command on client and server.
2321 * Implemented NAMES command on client and server. The server side
2322 supports currently only normal server not router server yet.
2323 Some changes to NAMES definition in SILC protocol specification.
2325 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Implemented LEAVE command on client and server.
2329 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2330 again. This change was made to the protocol as well. Server
2331 should not violate the protocol specification anymore.
2333 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2336 was tested. SOCKS4 was not but should work anyway.
