1 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed fatal bug in failure packet handling. Server ignored
4 the failiure and thus crashed when it came.
6 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
9 that the command may be executed only once in (about) 2 seconds.
10 The old SILC_CF_LAG flag is same but allows command bursts up
11 to five before limiting.
13 Added the support for CF_LAG and CF_LAG_STRICT flags to the
14 server code. Various commands now includes the CF_LAG_STRICT
15 flag to disallow any kind of miss-use of the command.
17 * Fixed the silc_buffer_unformat to not to allocate any data
18 if the length of the data is zero. It used to allocate the
19 length + 1. Affected file lib/silcutil/silcbuffmt.c.
21 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
23 * Changed the format of AdminConnection configuration section
24 in the server. Added username of the admin to the format.
25 Affected files silcd/serverconfig.[ch].
27 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
28 to return admin configuration data by host, username and/or
31 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Implemented WHOWAS command to the server. Added the functions:
35 silc_server_command_whowas_parse,
36 silc_server_command_whowas_send_reply,
37 silc_server_command_whowas_from_client and
38 silc_server_command_whowas_from_server
40 * Added <Client ID> argument to the WHOWAS command reply. Updated
41 the protocol specs accordingly.
43 * Implemented WHOWAS command and command_reply to the client
46 Implemented the WHOWAS printing on the user interface.
48 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * Added new argument to the WHOWAS command reply, the real name.
51 It is an optional argument. Updated the protocol specs.
53 * Added SilcIDCacheDestructor callback that is registered when
54 the SilcIDCache is allocated. The callback is called when
55 an cache entry in the ID Cache expires, or is purged from the
56 cache. Added into lib/silccore/idcache.[ch].
58 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
59 to destruct the client entries when the cache entry expires.
60 Other ID Cache's in server and in the client library ignores
63 * If the ID Cache entry's `expire' field is zero then the entry
64 never expires. Added boolean `expire' argument to the
65 silc_idcache_add function in the lib/silccore/idcache.[ch].
66 If it is TRUE the default expiry value is used.
68 * Added silc_server_free_client_data_timeout that is registered
69 when client disconnects. By default for 5 minutes we preserve
70 the client entry for history - for WHOWAS command.
72 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Added support to the server to enforce that commands are not
75 executed more than once in 2 seconds. If server receives
76 commands from client more frequently, timeout is registered
77 to process the commands. Affected file silcd/command.c.
78 Added new function silc_server_command_process_timeout.
80 * Changed NICK_NOTIFY handling in client library to check that
81 if the client's nickname was changed, so there is no need to
82 resolve anything from the server.
84 * Removed error printing from the WHOIS and IDENTIFY commands.
85 If error occurs then it is ignored silently in the client library.
86 The application, however, may map the received error to
87 human readable error string. The application currently maps
88 the NO_SUCH_NICKNAME error to string.
90 * Made the command status message public to the application. Moved
91 them from lib/silcclient/command_reply.c to
92 lib/silcclient/command_reply.h. The application can map the
93 received command status to the string with the
94 silc_client_command_status_message function.
96 * Added check to the server to check that client's ID is same
97 as the Source ID in the packet the client sent. They must
100 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Added dist-bzip hook to the Makefile.am to make bzip2
103 compressed distributions.
105 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
107 * Server now enforces the maximum length for the nickname and
108 the channel as protocol specification dictates. 128 bytes for
109 nickname and 256 bytes for channel name.
111 * Moved the WHOIS printing to the application. The client libary
112 does not print out the WHOIS information anymore, the application
113 must do it. Renamed silc_client_command_reply_whois_print to
114 the silc_client_command_reply_whois_save.
116 The client's idle time is also sent to the application now, and
117 the idle is shown on screen.
119 * Added silc_client_command_reply_identify_save to save the
120 received IDENTIFY entries.
122 * Do not check for channel private keys in message sending and
123 reception if the channel does not have the PRIVKEY mode set.
124 Affected file lib/silclient/client_channel.c.
126 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
129 just surfaced after chaning the JOIN procedure.
131 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Added silc_client_get_clients_by_list to get client entries
134 from Client ID list, that is returned for example by JOIN
135 and USERS command replies. The application should use this
136 function for example when JOIN command reply is received to
137 resolve the clients already on the channel (library does not
138 do that anymore as USERS command reply is not used in the JOIN
139 procedure anymore). Affected files lib/silcclient/silcapi.h and
140 lib/silcclient/idlist.c.
142 * JOIN command reply and USERS command reply returns now SilcBuffer
143 pointers instead of unsigned char pointers when returning
144 the client list and mode list.
146 * Added <Client ID> argument to the JOIN command reply, mainly
147 for the server to identify for which client the command was
148 originally sent. Updated protocol specs accordingly.
150 * Added SilcDlist private_key pointer to the SilcChannelEntry
151 in the client to support the channel private keys. Affected
152 file is lib/silcclient/idlist.h.
154 * Added SilcChannelPrivateKey argument to the function
155 silc_client_send_channel_message so that application can choose
156 to use specific private ke if it wants to. If it is not provided,
157 the normal channel key is used, unless private keys are set.
158 In this case the first (key that was added first) is used
159 as the encryption key.
161 * Implemented the support for channel private key handling.
162 Implemented the following functions:
164 silc_client_add_channel_private_key,
165 silc_client_del_channel_private_keys,
166 silc_client_del_channel_private_key,
167 silc_client_list_channel_private_keys and
168 silc_client_free_channel_private_keys
170 Affected file lib/silcclient/client_channel.c.
172 * Added the support for the private keys in the channel message
173 sending and encryption and in the message reception and
174 decryption. Affected funtions are
175 silc_client_send_channel_message and silc_client_channel_message.
177 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Added SKE's key verify callback to the client library's
180 KE protocol context. Affected files lib/silcclient/protocol.[ch].
182 * Removed the statement that server (or router) must send USERS
183 command reply when joining to the channel so that the client
184 knows who are on the channel. Instead, the client list and
185 client's mode list is now sent in the JOIN command reply to the
186 client who joined channel. This is better solution.
188 * Added function silc_server_get_users_on_channel and function
189 silc_server_save_users_on_channel to the silcd/server.[ch].
191 * Removed function silc_server_command_send_users from the
194 * Do not show topic on the client library anymore. The topic is
195 sent in the command reply notify to the application and the
196 application must show the topic now.
198 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
200 * Added client searching by nickname hash into the IDENTIFY and
201 WHOIS commands in the server as they were clearly missing from
202 them. Affected file is silcd/command.c.
204 * Fixed a bug in private message receiving in the client library.
205 The remote ID was freed and it wasn't supposed, now it is
208 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Minor fix to the channel payload; allocate the data area, as it
211 needs to be of specific length.
213 * If the key agreement port is zero then the operating
214 system will define the bound port. Affected files are
215 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
217 * Added new function silc_channel_payload_decrypt into the file
218 lib/silccore/silcchannel.[ch].
220 * Moved the channel message etc, check from silc_packet_decrypt
221 to applications. The library calls now a generic
222 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
223 when the packet is either normal or special. This was done to
224 allow more wide range of checking that was not allowed when
225 the code was in library. Now applications can do virtually any
226 checks to the packet and return to the library the decision how
227 the packet should be processed. Affected files are
228 lib/silccore/silcpacket.[ch].
230 Added silc_server_packet_decrypt_check to the server and
231 silc_client_packet_decrypt_check to the client library.
233 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
234 to send with specified source and destination information.
236 * Channel message delivery between routers was broken after the
237 channel key distribution was fixed earlier. The channel key
238 was used be to distributed to other routers as well which is not
239 allowed by the protocol. Now this is fixed and channel keys
240 really are cell specific and the channel message delivery between
241 routers comply with the protocol specification.
243 * Fixed various commands in server to check also the global list
244 for the channel entry and not just the local list. The affected
245 file silcd/command.c.
247 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Added assert()s to buffer formatting and unformatting routines
250 to assert (if --enable-debug) when error occurs. Affected
251 file: lib/silcutil/silcbuffmt.c.
253 * Changed to auto-reconnect to check whether the remote host is
254 router and register the re-connect timeout if it is. It used
255 to check that whether we are normal server, but router must do
256 auto-reconnect with another router as well. Affected file
259 * Removed the [<key len>] option from CMODE command as the cipher
260 name decides the key length, nowadays. See the defined ciphers
261 from the protocol specification.
263 * Added [<hmac>] option to the CMODE command to define the HMAC
264 for the channel. Added SILC_CMODE_HMAC channel mode.
266 * Added [<hmac>] option for the JOIN command so that user can
267 select which HMAC is used to compute the MACs of the channel
270 * Added Hmac field to the Channel Message Payload. The integrity
271 of plaintext channel messages are now protected by computing
272 MAC of the message and attaching the MAC to the payload. The
273 MAC is encrypted. Now, it is clear that this causes some
274 overhead to the size of the packet but rationale for this is that
275 now the receiver can verify whether the channel message decrypted
276 correctly and also when private keys are set for the channel the
277 receiver can decrypt the packet with several keys and check from
278 the MAC which key decrypted the message correctly.
280 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
281 lib/silccrypt/silccipher.[ch].
283 * Added silc_hash_len to return the digest length into the
284 lib/silcrypt/silchash.[ch].
286 * Rewrote parts of Silc Channel Payload interface in the
287 lib/silccore/silcchannel.[ch]. The encode function now also
288 encrypts the packet and parse function decrypts it.
290 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Fixed a minor formatting bug in the SKE's key material processing.
293 It actually might have processed the keys wrong way resulting
296 * Redefined the mandatory HMAC algorithms and added new algorithms.
297 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
298 and hmac-md5 truncated to 96 bits. The mandatory is now
299 hmac-sha1-96. Rest are optional (including the one that used
300 to be mandatory). Rationale for this is that the truncated HMAC
301 length is sufficient from security point of view and can actually
302 make the attack against the HMAC harder. Also, the truncated
303 HMAC causes less overhead to the packets. See the RFC2104 for
306 * Added new [hmac] configuration section. The SKE used to use
307 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
308 is of course wrong. The official names that must be proposed in
309 the SKE are the ones defined in the protocol specification
310 (hmac-sha1-96 for example). The user can configure any hmac
311 using any hash function configured in the [hash] section. At
312 least, the mandatory must be configured.
314 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
316 * Added HMAC list to the SKE proposal list. It has now both
317 hash algorithm list and HMAC list. This makes the protocol
318 incompatible with previous versions. The SKE now seems to work
319 the way it is supposed to work, for the first time actually.
321 * Defined plain Hash algorithms to the protocol specification.
324 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Implemented support for key agreement packets into the server.
327 Added functions silc_server_key_agreement and
328 silc_server_send_key_agreement. Other than these functions,
329 server has nothing to do with this packet.
331 * Added support for private message key packets into the server.
332 Added functions silc_server_private_message_key and
333 silc_server_send_private_message_key.
337 * Changed the silc_[client|server]_protocol_ke_set_keys to be
338 called in the protocol's final callback instead in the END
339 protocol state. This makes a little more sense and in the same
340 time in client we can use the same protocol routines for normal
341 key exchange and to key agreement packet handling as well.
343 * Added to both client's and server's KE protocol context the
344 SilcSKEKeyMaterial pointer to save the key material. We will
345 bring the key material to the protocol's final callback by doing
346 this. The final callback must free the key material.
348 * Added SKE's packet_send callback into client's KE protocol
349 context so that the caller can choose what packet sending function
350 is used. This way we can use different packet sending when
351 doing normal SKE when doing key agreement packet handling (in
352 the key agreement packet handling we do not want to encrypt
355 * Implemented the responder side of the key agreement routines
356 in the client. The client can now bind to specified port and
357 accept incoming key negotiation. The key material is passed
358 to the application after the protocol is over.
360 * Implemented the processing of incoming Key Agreement packet
361 in the client. Added function silc_client_key_agreement to
364 * Implemented the intiator side of the key agreement routines
365 in the client. The client can now initiate key agreement with
366 another remote client. The key material is passed to the
367 application after the protocol is over.
369 * Created client_keyagr.c to include all the key agreement
372 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
373 SILC_TASK_CALLBACK except that it is not static.
375 * Created client_notify.c and moved the Notify packet handling
376 from the client.[ch] into that file.
378 * Created client_prvmsg.c and moved all private message and
379 private message key routines from the client.[ch] into that file.
381 * Create client_channel.c and moved all channel message and
382 channel private key routines from the client.[ch] into that file.
384 * Changed silc_client_get_client_by_id_resolve to resolve with
385 WHOIS command instead of IDENTIFY command, in the file
386 lib/silclient/idlist.c.
388 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Implemented the SKE's responder side to the Client library.
392 * When FAILURE is received to the protocol do not trust it
393 blindly. Register a timeout to wait whether the remote closes
394 the connection as it should do it, only after that process the
395 actual failure. This was changed to both client and server.
397 * Added client_internal.h to include some of the structures
398 there instead of client.h in lib/silcclient/.
400 * Added function silc_task_unregister_by_callback to unregister
401 timeouts by the callback function.
403 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Some "Incomplete WHOIS info" errors has been appearing on the
406 log files. Took away the entry->userinfo check from WHOIS
407 reply sending. The entry->userinfo is now " " if client did not
408 provide one. I thought this was fixed earlier but something
409 is wrong still. Let's see if the error still appears.
411 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Fixed a minor bug in the login when the channel key is
414 re-generated in the server. It used to generate the key in
415 wrong order and thus caused problems in the channel traffic.
417 * Fixed a minor bug in channel key distsribution after
418 KICK command. The key was not sent to the router even though
421 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added silc_ske_process_key_material_data as generic routine
424 to process any key material as the SILC protocol dictates. The
425 function is used by the actual SKE library but can be used by
426 applications as well. This relates to the private message keys
427 and the channel private keys since they must be processed the
428 same way the normal SILC session keys. The protocol dictates
429 this. Affected files: lib/silcske/silcske.[ch].
431 Added also silc_ske_free_key_material to free the
432 SilcSKEKeyMaterial structure.
434 * Defined silc_cipher_set_key function to set the key for
435 cipher without using the object's method function. The affected
436 files: lib/silccrypt/silccipher.[ch].
438 * Implemented silc silc_client_add_private_message_key,
439 silc_client_add_private_message_key_ske,
440 silc_client_del_private_message_key,
441 silc_client_list_private_message_keys and
442 silc_client_free_private_message_keys functions in the
445 Added functions silc_client_send_private_message_key to send
446 the Private Message Key payload and silc_client_private_message_key
447 to handle incoming Private Message Key payload.
449 * Added Cipher field to the Private Message Key payload to set
450 the cipher to be used. If ignored, the default cipher defined
451 in the SILC protocol (aes-256-cbc) is used.
453 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Removed lib/silcclient/ops.h file.
457 Redefined parts of the SILC Client Library API. Created new
458 file silcapi.h that deprecates the ops.h file and defines the
459 published Client Library API. Defined also private message key
460 API and channel private key API into the file.
462 This is the file that the application must include from the
463 SILC Client Library. Other files need not be included by
464 the application anymore.
466 * Added new key_agreement client operation callback and also
467 defined the Key Agreement library API for the application.
469 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
472 is used by clients to request key negotiation between another
473 client in the SILC network. If the negotiation is started it
474 is performed using the SKE protocol. The result of the
475 negotiation, the secret key material, can be used for example
476 as private message key.
478 Implemented the Key Agreement payload into the files
479 lib/silccore/silauth.[ch].
481 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Redefined ciphers for the SILC protocol. Added some new ciphers
484 and defined the key lengths for the algorithms. Changed the
485 code accordingly. The default key length is now 256 bits.
487 * Fixed SKE key distribution function silc_ske_process_key_material
488 when the key length is more than 128 bits. The default key
489 length in SILC is now 256 bits.
491 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
492 to indicate unsupported algorithm.
494 * Renamed rijndael.c to aes.c and all functions as well.
496 * Fixed a long standing channel key setting bug in client library.
497 Weird that it has never surfaced before.
499 * Fixed bug in channel deletion. If the entire channel is removed
500 then it must also delete the references of the channel entry
501 from the client's channel list as the client's channel entry and
502 the channel's client entry share same memory.
504 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Implemented CONNECT and SHUTDOWN commands in the client.
508 * Implemented CLOSE command to the client.
510 * Added the function silc_idlist_find_server_by_name into the
511 files silcd/idlist.[ch].
513 Added the function silc_idlist_find_server_by_conn into the
514 files silcd/idlist.[ch].
516 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * DIE command was renamed to SHUTDOWN. Updated the both code
521 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
522 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
524 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
527 * Added function silc_server_create_connection function to create
528 connection to remote router. My server implementation actually
529 does not allow router to connect to normal server (it expects
530 that normal server always initiates the connection to the router)
531 so the CONNECT command is only good for connecting to another
534 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
537 or some other client was kicked from the channel.
539 Implemented the handling of the notify type to both client
542 Implemented silc_server_send_notify_kicked to send the KICKED
543 notify. It is used to send it to the server's primary router.
545 * Implemented the KICK command into server and client.
547 * Added `query' argument to the silc_idlist_get_client function
548 to indicate whether to query the client from server or not if
551 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
552 to indicate that the client is not channel founder.
556 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Removed the rng context from SilcPacketContext structure and
559 changed that the packet routine uses the Global RNG API.
561 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Added support for quit message that client can "leave" on the
564 channel when it quits the SILC. It is ditributed inside the
565 SILC_NOTIFY_TYPE_SIGNOFF notify type.
567 Added silc_server_free_client_data that will take the
568 signoff message as argument.
570 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
572 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Updated parts of the protocol specification to keep it up
577 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
580 payloads in one packet.
582 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
583 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
584 use now the new List flag.
586 * Also deprecated the following packet types: REPLACE_ID,
587 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
589 * Added list support for Notify packet in server.
591 * Added silc_server_send_notify_channel_change to send the
592 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
593 the silc_server_send_replace_id.
595 * Added silc_server_send_notify_nick_change to send the
596 NICK_CHANGE notify type. Deprecates the function
597 silc_server_send_replace_id.
599 * Added silc_server_send_notify_join to send the JOIN notify type.
600 Deprecates the function silc_server_send_new_channel_user.
602 * Added silc_server_send_notify_leave to send LEAVE notify type.
603 Deprecates the function silc_server_send_remove_channel_user.
605 * Added silc_server_send_notify_cmode and
606 silc_server_send_notify_cumode to send CMODE and CUMODE notify
607 types. Deprecates the silc_server_send_set_mode function.
609 * Added SERVER_SIGNOFF notify type to indicate that server has
610 quit. This means that all clients on the channel from that
611 server will drop. This can be also used when netsplit happens.
613 Deprecated REMOVE_ID packet type since it is not needed anymore
616 Added silc_server_send_notify_server_signoff to send the
617 SERVER_SIGNOFF notify type. Deprecates the function
618 silc_server_send_remove_id.
620 Added also silc_server_send_notify_signoff to send the
623 * Employed the PKCS #1. It is the mandatory way to do RSA in the
624 SILC protocol from this day on. Changed the protocol
625 specification as well.
627 * Added silc_server_send_notify_topic_set to send TOPIC_SET
628 notify type. It is used between routers to notify about
629 topic changes on a channel.
631 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
634 * Partly updated the protocol specification to comply with the
635 changes now made. It is still though a bit outdated.
637 * The JOIN notify type now takes one extra argument <Channel ID>.
638 The packet used to be destined to the channel but now the
639 JOIN type may be sent as list thus it is impossible to
640 destine it to any specific channel. By adding this argument
641 it is again possible.
643 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Added CREDITS file. The CHANGES and CREDITS file will appear
646 in the distribution as well.
648 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
651 types in the server's silcd/packet_receive.c.
653 * Implemented CMODE and CUMODE to work in router environment.
655 * Fixed minor encoding and decoding buglet from the
656 lib/silccore/silcmode.c.
658 * Fixed buffer overflow from lib/silcclient/command.c in USERS
661 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
663 * Changed all SilcConfigServer* and silc_config_server* to
664 SilcServerConfig* and silc_server_config*, respectively.
667 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Associated the ID (client or server ID) to the Authentication
670 Payload to avoid any possibility of forging. Updated the
671 protocol specification and the code accordingly.
673 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * The RSA key length is now save to the RsaKey context in the
676 key generation process in lib/silccrypt/rsa.c. The key length
677 is now used to figure out the maximum size of the block allowed
678 to be encrypted/signed.
680 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
681 is equivalent to the silc_mp_mp2bin but does not allocate any
684 * Changed silc_mp_mp2bin API to take length argument. If it is
685 non-zero then the buffer is allocated that large. If zero, then
686 the size is approximated using silc_mp_sizeinbase, which however
689 * Created Global RNG API which is global RNG that application can
690 initialize. After initializing, any routine anywhere in the
691 code (including library) can use RNG without allocating a new
692 RNG object. This was done to allow this sort of use of the
693 RNG in code that has no chance to allocate RNG object. All
694 applications currently allocate this and many routines in the
695 library use this. Affected file lib/silccrypt/silcrng.[ch].
697 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
698 it to use the Global RNG API.
700 * Defined Authentication Payload into protocol specification that
701 is used during SILC session to authenticate entities. It is
702 used for example by client to authenticate itself to the server
703 to obtain server operator privileges.
705 Implemented this payload into the lib/silccore/silcauth.[ch].
706 Implemented also routines for public key based authentication
707 as the new protocol specification dictates.
709 Moved definitions of different authentication methods from
710 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
712 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
713 silc_pkcs_verify and silc_pkcs_sign_with_hash and
714 silc_pkcs_verify_with_hash functions into the file
715 lib/silccrypt/silcpkcs.[ch].
717 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * The client entry's userinfo pointer must be always valid.
720 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
721 will fail since it requires the userinfo. Now, the userinfo
722 is allocated as "" if actual userinfo does not exist. Actually,
723 it must exist and it is totally Ok to drop client connections
724 that does not announce the userinfo. However, we will make
725 this workaround for now.
727 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
728 to return the remote port by socket.
730 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
733 SILC_SERVER_PENDING_EXEC and added an new macro
734 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
735 data or when error occurs while processing the pending command.
737 Added new argument `destructor' into silc_server_command_pending
738 and to the SilcServerCommandPending object. This destructor is
739 now called after calling the pending callback or if error occurs
740 immediately. If error occurs the actual pending callback won't
741 be called at all - only the destructor. The destructor may be
742 NULL if destructor is not needed.
744 All this applies for client library code as well. Similar
745 changes were made there as well for the pending commands.
747 In the client, the application must now allocate the
748 SilcClientCommandContext with the silc_client_command_alloc
751 * Added reference counter to the SilcServerCommandContext. Added
752 function silc_server_command_alloc and silc_server_command_dup
755 Same type of functions added to the client library for the same
758 * Removed the cmd_ident from IDListData away since it is now
759 global for all connections. It is the command identifier used
760 in command sending and with pending commands. The affected file
763 * Added reference counter to the SilcSocketConnection objecet to
764 indicate the usage count of the object. The object won't be
765 freed untill the reference counter hits zero. Currently only
766 server uses this, and client ignores it. The client must be
767 set to use this too later. The affected files are
768 lib/silccore/silcsockconn.[ch]. Added also the function
769 silc_socket_dup to increase the reference counter.
771 This was mainly added because it is possible that the socket
772 is removed underneath of pending command or other async
773 operation. Now it won't be free'd and proper DISCONNECTING
774 flags, etc. can be set to avoid sending data to connection that
775 is not valid anymore.
777 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
778 the connection. After that it sets SILC_SET_DISCONNECTED.
779 It is, however, possible that the socket data is not still freed.
780 The silc_server_packet_process now checks that data is not
781 read or written to connection that is DISCONNECTED. The socket
782 get's freed when the reference counter hits zero.
784 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
786 * Changed the client operation API: channel_message operation's
787 `sender' is now the client entry of the sender, not the nickname
788 and the `channel' is the channel entry, not the channel name.
790 In the private_message operation the `sender' is now also the
791 client entry of the sender not the nickname.
793 Affected file is lib/silcclient/ops.h and all applications
794 using the client operations.
796 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Moved the calling of ops->connect() from connect_to_server_final
799 into receive_new_id functin since that is the point when the
800 client is actually allowed to send traffic to network. The
801 affected file is lib/silcclient/client.c.
803 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
806 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
807 (if needs broadcasting) instead of broadcasting the packets one
808 by one which would make a burst in the network traffic.
810 * Added `broadcast' argument to the functions in silcd/server.[ch]
811 silc_server_create_new_channel[_with_id] to indicate whether
812 to send New Channel packet to primary router.
814 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
816 * Added new function into the silcd/server.[ch] files:
817 silc_server_create_new_channel_with_id to create new channel with
818 already existing Channel ID.
820 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
821 lib/silccore/silcpacket.h. This packet is used t send list of
822 Set Mode payloads inside one packet. Server uses this to set
823 the modes for the channels and clients on those channels, that it
824 announced to the router when it connected to it. The protocol
825 specification has been updated accordingly.
827 * The silc_server_new_channel did not handle the packet coming
828 from normal server as it normally does not send that. However,
829 when it announces its channels it does send it. Implemented
830 the support for that.
832 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
833 into the file lib/silccore/id.h.
835 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Fixed memory leaks in the functions silc_idlist_del_client,
838 silc_idlist_del_channel and silc_idlist_del_server in the file
839 silcd/idlist.c. All of those leaked like a sieve.
841 * Fixed some small memory leaks in the client's function
842 silc_client_notify_by_server.
844 * Added functions into silcd/server.c: silc_server_announce_clients,
845 silc_server_announce_channels and silc_server_announce_server.
846 These functions are used by normal and router server to announce
847 to its primary router about clients, channels and servers (when
848 router) that we own. This is done after we've connected to the
851 These functions effectively implements the following packet types:
852 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
853 and SILC_PACKET_NEW_ID_LIST.
855 * Added new functions into the silcd/packet_receive.[ch]:
856 silc_server_new_id_list, silc_server_new_channel_list and
857 silc_server_new_channel_user_list to handle the incoming
858 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
860 * Added support of changing Channel ID in the function
861 silc_server_replace_id. If the server that announces a channel
862 to the router already exists in the router (with same name but
863 with different Channel ID), router is responsible to send
864 Replace ID packet to the server and force the server to change
865 the Channel ID to the one router has.
867 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
868 client that the Channel ID has been changed by the router. The
869 normal server sends this to the client. Client must start using
870 the new Channel ID as the channel's ID.
872 Implemented handling of this new type into lib/silcclient/client.c
873 into the function silc_client_notify_by_server.
875 * Added new function silc_idlist_replace_channel_id into the files
876 silcd/idlist.[ch] to replace the Channel ID.
878 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Call silc_server_command_identify_check always when processing
881 the IDENTIFY command in silcd/command.c
883 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
886 send keepalive packets. The packet can be sent by clients,
889 Added function silc_socket_set_heartbeat into the file
890 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
891 If not set, the heartbeat is not performed. The actual
892 heartbeat is implemented in the low level socket connection
893 library. However, application is responsible of actually
896 Added silc_server_send_heartbeat to send the actual heartbeat
897 packet into silcd/packet_send.[ch]. Server now performs
898 keepalive with all connections.
900 * Added silc_task_get_first function into lib/silcutil/silctask.c
901 to return the timeout task with shortest timeout. There was a bug
902 in task unregistration that caused problems. TODO has been
903 updated to include that task system must be rewritten.
905 * The client library will now resolve the client information when
906 receiving JOIN notify from server for client that we know but
907 have incomplete information.
909 * Rewrote parts of silc_server_remove_from_channels and
910 silc_server_remove_from_one_channel as they did not remove the
911 channel in some circumstances even though they should've.
913 * Encryption problem encountered in server:
915 The LEAVE command used to send the Channel Key packet to the
916 router immediately after generating it. However, the code
917 had earlier sent Remove Channel user packet but not immediately,
918 ie. it was put to queue. The order of packets in the router
919 was that Channel Key packet was first and Remove Channel User
920 packet was second, even though they were encrypted in the
921 reverse order. For this reason, MAC check failed. Now, this
922 is fixed by not sending the Channel Key packet immediately but
923 putting it to queue. However, this is more fundamental problem:
924 packets that are in queue should actually not be encrypted
925 because packets that are sent immediately gets encrypted
926 actually with wrong IV (and thus MAC check fails). So, packets
927 that are in queue should be encrypted when they are sent to
928 the wire and not when they put to the queue.
930 However, the problem is that the current system has not been
931 designed to work that way. Instead, the packet is encrypted
932 as soon as possible and left to the queue. The queue is then
933 just purged into wire. There won't be any fixes for this
934 any time soon. So, the current semantic for packet sending
937 o If you send packet to remote host and do not force the send
938 (the packet will be in queue) then all subsequent packets to the
939 same remote host must also be put to the queue. Only after the
940 queue has been purged is it safe again to force the packet
943 o If you send all packets immediately then it safe to send
944 any of subsequent packets through the queue, however, after
945 the first packet is put to queue then any subsequent packets
946 must also be put to the queue.
948 Follow these rules and everything works fine.
950 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Added new function silc_server_remove_clients_by_server to
953 remove all client entries from ID list when the server connection
954 is lost. In this case it is also important to invalidate all
955 client entires as they hold the invalid server entry. This
956 fixes fatal bug when server has lost connection and will reconnect
959 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Made some sanity checks to silc_server_daemonise like to check
962 whether the requested user and group actually exists.
964 * Added sanity check to SKE's silc_ske_responder_finish to check
965 that the public and private key actually is valid.
967 * Invalidate the client's nickname when receiving Replace ID
968 packet and the Client ID is being replaced. This means that the
969 server will query the nickname if someone needs it (client)
972 * Sort the ID Cache in client library when the ID Cache data
973 has changed (needs sorting).
975 * Do not allow for SILC client to create several connections to
976 several servers. The client does not support windows right now
977 and generating multiple connections causes weird behaviour.
979 Irssi-silc client does support windows and can handle several
980 connections without problems, see: www.irssi.org and SILC plugin.
982 * Fixed some places where client was added to the IDList. The
983 rule of thumb is following (in order to get everything right):
984 If the client is directly connected local client then the
985 `connection' argument must be set and `router' argument must be
986 NULL to silc_idlist_add_client function. If the client is not
987 directly connected client then the `router' argument must
988 bet set and the `connection' argument must be NULL to the
989 silc_idlist_add_client function.
991 * The funtion silc_server_packet_send_local_channel actually did
992 not check whether the client was locally connected or not. It
993 does that now. Fixed a bug related to LEAVE command.
995 * Fixed Remove Channel User payload parsing bug in server's
996 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
998 * The server's silc_server_save_channel_key now checks also the
999 global ID list for the channel as it might not be in the local
1000 list. Fixed a bug related to LEAVE command.
1002 * Is this the end of the [<unknown>] buglet that has been lurking
1003 around for a long time? A little for loop fix in server's
1004 silc_server_command_whois_parse that is used by both IDENTIFY
1005 and WHOIS command. At least, this was a clear bug and a cause
1006 of one type of [<unknown>] buglet.
1008 * WHOIS and IDENTIFY commands call the function
1009 silc_server_command_[whois/identify]_check function even if
1010 we are not router server.
1012 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Added --with-gmp configuration option. If set the GMP
1015 is always compiled in the SILC source tree. If not set then
1016 it is checked whether the system has the GMP3 installed. If
1017 it has then the GMP won't be compiled (the system's headers
1018 and library is used), if it doesn't have it then the GMP is
1019 compiled in the SILC source tree.
1021 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Changed RSA private exponent generation to what PKCS #1
1024 suggests. We try to find the smallest possible d by doing
1025 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1026 not security fix but optimization.
1028 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1030 * Added new config entry [Identity] to fork the server and run
1031 it as specific user and group. A patch from Bostik.
1033 * Imported Dotconf configuration library into lib/dotconf.
1034 This will be used to create the SILC configuration files later.
1035 It will appear in the distsribution after this commit.
1037 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * A big code auditing weekend happening. Auditing code for
1040 obvious mistakes, bugs and errors. Also, removing any code
1043 Removed files for being obsolete:
1045 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1046 inline in the file lib/silcutil/silcbuffer.h)
1048 o lib/silcutil/silcbufutil.c (the header has inline versions)
1050 Changed code to fix possible error conditions:
1052 o The buffer formatting routines now check that the destination
1053 buffer really has enough space to add the data. This applies for
1054 both buffer formatting and unformatting
1055 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1056 unformatting was changed to accomodate following rules:
1057 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1058 sent to the function while XXX_*STRING will not allocate or copy
1059 the data into the buffer. Instead it sets the pointer from the
1060 buffer into the pointer sent as argument (XXX_*STRING used to
1061 require that the pointer must be allocated already). This change
1062 makes this whole thing a bit more consistent and more optimized
1063 (note that the data returned in the unformatting with XXX_*STRING
1064 must not be freed now). The routines return now -1 on error.
1066 o Tried to find all code that use buffer_format and buffer_unformat
1067 and added return value checking to prevent formatting and
1068 especially unformatting errors and possible subsequent fatal
1071 o Changed ske->x and ske->KEY to mallocated pointers in
1072 lib/silcske/silcske.h. Fixed possible data and memory leak.
1074 o Added return value checking to all *_parse* functions. Fixed
1075 many memory leaks as well.
1077 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1078 so that buffer overflows would not happen. All code now also
1079 checks the return value as it can fail.
1081 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1083 * Added reconnection support to server if the normal server looses
1084 its connection to the router (for example if router is rebooted).
1085 The server performs normal reconnection strategy implemented
1086 to the server. Affected file silcd/server.c.
1088 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Added new packet type SILC_PACKET_SET_MODE that is used to
1091 distribute the information about changed modes (for clients,
1092 channels and clients channel modes) to all routers in the
1093 network. Updated the protocol specification accordingly.
1095 Added functions into silcd/packet_send.c and
1096 silcd/packet_receive.c: silc_server_send_set_mode,
1097 silc_server_set_mode.
1099 Added new files silcmode.[ch] into lib/silccore that implements
1100 the encoding and decoding of Set Mode Payload. Added new type
1101 SilcSetModePayload. Moved the definitions of different modes
1102 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1104 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1106 * Oops, a little mistake in server's connection authentication
1107 protocol. The protocol is not ended with FAILURE but with
1108 SUCCESS if the authentication is Ok. :) Affected file is
1111 * Implemented NICK_CHANGE notify handling in server in the file
1112 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1113 the local clients on the channel. After the changing nickname
1114 in router environment snhould work and the [<unknown>] nickname
1115 should appear no more.
1117 The silc_server_replace_id function that receives the Replace ID
1118 payload now sends the NICK_CHANGE notify type also in the file
1119 silcd/packet_receive.c
1121 * Changed WHOIS and IDENTIFY command to support the maximum amount
1122 of arguments defined in protocol specs (3328 arguments). This
1123 fixed a bug that caused problems when there were more than three
1126 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Added extra parameter, command identifier, to the
1129 silc_client_send_command so that explicit command identifier
1132 Changed that ID list routines uses specific command identifier
1133 when sending WHOIS/IDENTIFY requests to the server so that they
1134 can be identified when the reply comes back.
1136 Affected files lib/silcclient/command.[ch],
1137 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1139 * Added `sender' argument to silc_server_packet_send_to_channel
1140 to indicaet the sender who originally sent the packet to us
1141 that we are now re-sending. Ignored if NULL. Affected file
1142 silcd/packet_send.[ch].
1144 * Added some server statistics support in silcd/server_internal.h
1145 SilcServerStatistics structure and around the server code. Also
1146 send some nice statistics information when client is connecting
1149 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Fixed channel ID decoding in server's JOIN command reply in
1152 silcd/command_reply.c
1154 * Fixed braodcasting of replace ID payload to not to send it if
1155 we are standalone server in silcd/packet_receive.c.
1157 * Fixed all channel message sending routines to not to send
1158 packets to clients that has router set, since they are routed
1159 separately in the same function earlier. Affects file
1160 silcd/packet_send.c and all channel packet sending functions.
1162 * In USERS reply, res_argv[i] are not allocated, the table
1163 is allocated. Thus changed that free the table, not its
1166 * In server's whois_check and identify_check if the client is
1167 locally connected do not send any WHOIS commands - they are not
1170 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Fixed some minor bugs in client when sending WHOIS command. The
1173 arguments was in wrong order.
1175 * Removed statis function add_to_channel from server in
1176 silcd/command.c that was previously used with the joining but
1179 * Tested USERS command in router environment successfully with two
1180 routers, two servers and two clients.
1182 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Reorganized the USERS command and command reply in client library
1185 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1186 When the command is given by user we register a pending command
1187 callback that will reprocess the command after the reply has been
1188 received from the server. When reprocessing the packet we then
1189 display the information. Thus, the USERS information is displayed
1190 now in the command callback instead of in the command reply
1191 callback. The processing of the command is same as previously
1192 when server has sent the command reply in the JOINing process.
1194 * Added to USERS command in silcd/command_reply.c to join the client,
1195 we didn't use to know about, to the channel after we've created
1196 a client entry for it. Also, for clienet we did know already still
1197 check whether it is on the channel or not and add it if not.
1199 * Removed silc_server_command_join_notify as the function and its
1202 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Changed the client's pending command handling to the same as the
1205 server's pending command handling. It is also now possible to
1206 execute command reply functions from other command reply
1207 function as the function callbacks for commands and command
1208 replies are one and same. The pending commands are not static
1209 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1210 in client connection context. Thus, pending commands are server
1211 connection specific as it is convenient.
1213 Changed the function silc_client_command_pending and
1214 silc_client_command_pending_del and added new function
1215 silc_client_command_pending_check. Removed the
1216 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1219 * Added cmd_ident, current command identifier, to the client
1220 connection context in lib/silcclient/client.h to keep track on
1221 command identifiers used in command sending. Client's command reply
1222 function handling now supports the mandatory command identifiers.
1224 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1225 funtions in client to fully support pending command callbacks.
1227 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1228 as one of the arguments to the application in the command reply
1231 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1232 before first releasing SILC but came back. Now it is removed again
1233 and should come back nomore. The FORWARDED flag was used only
1234 by the JOINing procedure by forwarding the command packet to router.
1235 Now, the JOINing procedure has been changed to more generic (due
1236 to various router environment issues) and FORWARDED is not needed
1237 anymore for anything. The protocol specification is yet to be
1240 Now, removed silc_server_packet_forward from server and the flag
1241 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1243 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Renamed NAMES command to USERS command. The NAMES was named that
1246 due to historical reasons. Now it is renamed. Also, rewrote
1247 parts of the USERS command. The nickname list is not sent anymore
1248 by the server. Only Client ID and mode lists are sent in the USERS
1249 command. Changed this also to the protocol specification.
1251 The client now resolves the names and stuff after it receives
1252 the USERS list from the server when joining to the channel.
1254 * WHOIS and IDENTIFY commands has been changed to support multiple
1255 Client ID's per command. One can now search for multiple users
1256 in the network by sending only one WHOIS or IDENTIFY command.
1257 Changed the code and the protocol specifications.
1259 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1260 uses silc_server_command_whois_parse to parse the request. */
1262 * If normal server, do not parse the WHOIS and IDENTIFY requests
1263 before sending it to the router. Saves some time.
1265 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Fixed JOIN command on client library. Wrong number of arguments
1268 used to crash the client.
1270 * Added silc_server_channel_has_global function to check whether
1271 channel has global users or not.
1273 * Added silc_server_channel_has_local function to check whether channel
1274 has locally connected clients on the channel.
1276 * The silc_server_remove_from_one_channel now checks whether the
1277 channel has global users or not after given client was removed from
1278 the channel. It also checks whether the channel has local clients
1279 on the channel anymore. If it does not have then the channel entry
1280 is removed as it is not needed anymore.
1282 * The silc_server_notify now checks on JOIN notify whether the joining
1283 client is one of locally connected or global. If it is global then
1284 the channel has now global users on the channel and that is marked
1285 to the channel entry. Also, it now saves the global client to
1286 global list who is joining and JOINs it to the channel. This is
1287 for normal server, that is.
1289 Changed silc_server_send_notify_on_channel,
1290 silc_server_packet_relay_to_channel and
1291 silc_server_packet_send_to_channel check if we are normal server
1292 and client has router set (ie. global client) do not send the
1293 message to that client, as it is already routed to our router.
1295 * Implemented LEAVE notify type handling in silc_server_notify
1298 * Tested LEAVE command in router environment successfully. Tested
1299 with two routers, two servers and two clients.
1303 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1305 * Implemented SIGNOFF notify type handling in silc_server_notify
1308 * silc_server_remove_id now removes the client entry from all channels
1309 it has joined and thusly sends SIGNOFF notify type.
1311 * Rewrote the NAMES list generation in server by removing two excess
1312 loops. The lists are created now inside one loop.
1314 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * silc_server_remove_channel_user checks now also global list
1317 for channel and client.
1319 * silc_server_new_channel_user checks now both local and global
1320 list for channel and client. Fixed a bug in client id decoding.
1321 Used to decode wrong buffer.
1323 * silc_server_channel_message checks now both local and global
1324 list for channel entry.
1326 * Tested channel joining (hence JOIN) in router environment
1327 successfully. Tested with two routers, two servers and two
1330 * Tested channel message sending in router environment successfully.
1332 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added silc_server_save_channel_key into server.[ch] to save the
1335 received channel key in Channel Key payload processing. It is
1336 also used in JOIN command reply handling.
1338 Equivalent function silc_client_save_channel_key added into
1339 client.[ch] into client library.
1341 * Changed JOIN command reply to send information whether the channel
1342 was created or not (is existing already) and the channel key
1343 payload. Changed protocol specs accordingly.
1345 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1346 the request was sent by ID and not by nickname. Crashed on
1349 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1352 now correctly save the received data.
1354 * silc_server_free_sock_user_data now notifies routers in the
1355 network about entities leaving the network.
1357 At the same time implemented functions silc_server_remove_id
1358 and silc_server_send_remove_id to receive and send REMOVE_ID
1359 packets. The packet is used to notify routers in the network
1360 about leaving entities. The ID removed will become invalid in
1363 * Added function silc_idlist_del_server into server. Removes and
1364 free's server entry from ID list.
1366 * silc_server_private_message function now checks, if we are router,
1367 that the destination ID really is valid ID, naturally.
1369 * In router when NEW_ID packet is received (for new client) the
1370 hash of the Client ID is saved in the ID Cache but the
1371 client->nickname is set to NULL, instead of putting the hash
1374 IDENTIFY command now also checks that client->nickname must be
1375 valid. If it is not if will request the data from the server who
1376 owns the client. Added new function
1377 silc_server_command_identify_check.
1379 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1380 to set the command to already allocated Command Payload.
1382 * Tested private message sending in router environment with two
1383 routers, two servers and two clients. Fixed minor bugs and now
1386 * Fixed segfault from client's NAMES command. Used to crash if
1389 * Forwarded packets must not be routed even if it is not destined
1390 to the receiver. Changed server code comply with this.
1392 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Added `require_reverse_mapping' boolean value to ServerParams
1395 structure. If TRUE (not default) the server will require that
1396 the connecting host has fully qualified domain name.
1398 If the reverse mapping is not required and hostname could not be
1399 found the IP address is used as hostname.
1401 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Implemented version string checking to both client and server.
1404 The check is incomplete currently due to the abnormal version
1405 strings used in development version of SILC.
1407 * Changed all command functions in server to use the new
1410 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Changed char *data to unsigned char *data in ID Cache system to
1413 support binary data as ID Cache data. Changed code to support
1414 binary data in lib/silccore/idcache.c.
1416 * Renamed silc_server_packet_relay_command_reply to
1417 silc_server_command_reply as it is normal packet receiving
1418 function. Rewrote the function to accept command replys for
1419 servers and not only for clients.
1421 * Mark remote router always as registered server if we are connecting
1422 to it. Otherwise, commands sent by the router to us are ignored.
1424 * All ID List find routines now returns the ID Cache Entry pointer
1425 as well if requested.
1427 * WHOIS command works now in router environment, tested with two
1428 routers, two servers and two clients.
1430 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1431 in router environment (as it is almost equivalent to WHOIS) but
1432 hasn't been tested thoroughly. Added new functions:
1434 silc_server_command_identify_parse
1435 silc_server_command_identify_send_reply
1436 silc_server_command_identify_from_client
1437 silc_server_command_identify_from_server
1439 * Disabled route cache adding because adding two different ID's with
1440 same IP replaces the old cache entry thus giving wrong route.
1441 The entry->router->connection is always the fastest route anyway
1442 so route cache may not be needed. Of course, new routes maybe
1443 established after receiving the ID when the entry->router->connection
1444 might not be anymore the most optimal.
1446 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Add route cache for received ID for fast routing.
1450 * Added silc_server_packet_route to route received packet on router
1451 that is not destined to us.
1453 * Renamed silc_server_get_route to silc_server_route_get.
1455 * Added id_string and id_string_len fields into SilcServer to
1456 include encoded ServerID for fast comparing without excess
1457 encoding of the ID's.
1459 * Cleaned up WHOIS command on server side. Added following static
1462 silc_server_command_whois_parse
1463 silc_server_command_whois_check
1464 silc_server_command_whois_send_reply
1465 silc_server_command_whois_from_client
1466 silc_server_command_whois_from_server
1468 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1469 arguments in command replies. All command functions should be
1470 updated to use this macro.
1472 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Minor typo fixes on command reply handling on server.
1476 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Added silc_server_command_add_to_channel internal routine to add
1479 the client to the channel after router has created the channel and
1480 sent command reply to the server.
1482 * Added generic silc_server_send_command to send any command from
1485 * Use static buffer with ID rendering instead of duplicating data.
1487 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Fixed a channel user mode bug when joining to a channel server gave
1490 everybody channel founder rights, oops.
1492 * We mark ourselves as the router of the incoming server connection
1493 if we are router ourselves. This way we can check in some packet
1494 sending functions whether it is locally connected server. For
1495 incoming router connections we put NULL.
1497 * For router sending packets locally means now always sending the
1498 packet cell wide; to local clients and local servers. For normal
1499 server sending packet locally means sending it to only local
1502 * Fixed the JOIN command to really work in router environment. If the
1503 channel is created it is always created by the router. Router is
1504 also responsible of making the initial joining to the channel,
1505 sending JOIN notify to the sending server and distributing
1506 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1507 does not exist server doesn't do anything else but forward the
1508 command to the router which performs everything.
1510 * Added silc_server_send_channel_key function to send the Channel Key
1513 * Added silc_server_create_channel_key to create new channel key. The
1514 channel key is now re-generated everytime someone joins or leaves
1515 a channel, as protocol dictates. Note: channel->key_len is the
1518 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1521 packet_receive.[ch] to separate packet sending and receiving
1522 routines. The server.[ch] now includes everything else including
1523 actual packet processing (writing and reading data) and other
1526 Renamed silc_server_private_message_send_internal to
1527 silc_server_send_private_message. The routine is still though
1528 used only to relay private messages as server does not send
1529 private messages itself.
1531 Renamed silc_server_new_channel to silc_server_create_new_channel
1532 and added new function sicl_server_new_channel that handles the
1533 incoming New Channel packet. Added also new sending function
1534 silc_server_send_new_channel to send New Channel Payload.
1536 * Added new function silc_server_notify to process incoming notify
1537 packet to the server/router. Server may then relay the notify
1538 to clients if needed.
1540 * Added new function silc_server_new_channel_user to process incoming
1541 New Channel User packet. Router will redistribute the packet and
1542 send JOIN notify to its local clients and locally connected servers
1543 if needed. Normal server will send JOIN notify to its local client
1544 on same channel when received this packet. Added also corresponding
1545 sending function silc_server_send_new_channel_user to sent the
1548 * Added boolean route argument to send_notif_to_channel and
1549 packet_send_to_channel functions to attempt to route the packet
1550 if it is TRUE and send only locally if it is FALSE.
1552 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * silc_server_replace_id now broadcasts the received replace ID
1555 packet if it is not broadcast packet already. The router must
1556 broadcast to inform other routers about changed ID.
1558 * Added backpointer to server's router into SilcServer context in
1559 silcd/server_internal.h.
1561 * Fixed silc_server_packet_broadcast to send correct broadcast
1564 * The channel key is now distributed to the local client as soon
1565 as it is received from the router (in router environment) so that
1566 no other packet may be sent for the channel until client has
1569 * silc_server_remove_channel_user now broadcasts the received
1570 Remove Channel User packet if it is not broadcast packet already.
1571 The router must broadcast to inform other routers about removed
1574 * Added users field into SilcPacketContext that is a reference count
1575 of the context. One can increase the reference count by calling
1576 silc_packet_context_dup which is now changed to just increase the
1577 reference count instead of duplicating the data. The reference
1578 count is decresed by calling silc_packet_context_free that will
1579 free the data after the reference count hits zero.
1581 For now on the packet context and everything allocated into it
1582 (including the raw packet from network) must be freed by calling
1583 the new silc_packet_context_free function. Added also new function
1584 silc_packet_context_alloc that must be used now to allocate the
1585 context. This also means that if a routine is asynchronous from
1586 silc_[client/server]_packet_parse_type the packet context must
1587 be duplicated by calling silc_packet_context_dup. Otherwise it
1588 gets free'd after silc_[client/server]_packet_parse_type returns.
1589 Also, one must remember that if packet is duplicated then its
1590 reference count must be decresed by calling the free function as
1591 many times as it was duplicated.
1593 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1594 from both client and server.
1596 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Made joining to a channel working in router environment.
1600 * Cleaned up JOIN command on server side and create function
1601 silc_server_command_join_channel internal routine to make the
1604 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Changed silc_command_pending list to SilcDList. Also, added
1607 `ident' field to SilcServerCommandPending structure to identify
1608 the reply and to call correct callback.
1610 Added silc_server_command_pending_check function to replace the
1611 corresnponding macro. The silc_command_pending list is not
1614 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1615 to set identifier to previously allocated Command Payload. It
1616 is used to set identifier for command when resending Command
1619 * Added silc_command_payload_encode_payload to encode Command
1620 Payload buffer from SilcCommandPayload structure.
1622 * Added silc_argument_payload_encode_payload to encode Argument
1623 payload buffer from SilcArgumentPayload structure.
1625 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Changed WHOIS command to support router connection on server side.
1628 The whois request is always sent to router unless the server is
1629 standalone server. After server has received the reply from the
1630 router will it send the reply to the client.
1632 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1633 broadcast received broadcast packet. The function is used only
1634 by router. The broadcast packet is always sent to the router's
1637 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1638 render given ID to printable string, for log files for example.
1640 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Made basic router to router connections working. At least they
1643 can now connect to each other but nothing really works the way
1644 they are supposed - yet.
1646 * Added new initiator token to RouterConnection configuration
1647 file in silcd/serverconfig.[ch]. It is used to tell whether we
1648 are the initiator to the remote router or whether we'll expect
1649 the other end to connect.
1651 * Moved registering of listener task to silc_server_init, hence
1652 the server starts listenning as soon as it is run, even if it
1653 does not have connections to other routers. Let's see how well
1656 * Changed default connection retry timeouts for more suitable in
1659 * Removed cipher and such arguments from silc_idlist_add_client
1660 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1661 Added new function silc_idlist_add_data to add the keys and stuff
1664 * Added SilcIDListData structure and added it to SilcClientEntry
1665 and SilcServerEntry as their first field in the structure. This
1666 way we can explicitly cast the ID entries to the SilcIDListData
1667 structure and get common data for the entries. In past, we had
1668 to first check what type of connection it is and then cast it to
1669 correct ID entry type. Now, we can directly cast the opaque
1670 pointer to the SilcIDListData (no matter what ID entry it actually
1671 is) and get the data needed.
1673 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1676 in some circumstances even if threre were timeout tasks, though not
1677 IO tasks, but tasks anyway. Now fixed.
1679 * Defined SilcServerConnection structure to hold connection specific
1680 stuff about directly connected servers and routers. The definition
1681 is currently in silcd/server_internal.h. I thought about having
1682 a bit more important role fro this struct but for now it is used
1683 only when connecting to other server (or router actually).
1685 * Added connecting retry support in server when connecting to
1686 router(s). The retry feature implement exponential backoff
1687 algorithm. Also, added SilcServerParams structure to hold default
1688 parameters for server. For now, it include these retry settings
1689 and are hard coded. After server is moded to be as Silc Server
1690 Library this structure will be more important.
1692 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Changed client librarys channel->clients table to SilcList and
1695 changed code accordingly.
1697 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Changed client's channel table to SilcList and changed code
1700 accordingly. Also changed SilcChannelClientEntry to include back-
1701 pointer to the channel so that client entry can use that structure
1702 as list as well and we have fast cross-reference to the channel.
1703 This change dramatically decreased the complexity of channel
1704 handling with client entry and vice versa (removed one extra
1705 loop when searching for channel entry from many functions).
1707 * Changed server->sim from table to SilcDList and changed code
1710 * NAMES command can now be used from user interface. It will show
1711 the user list on the channel, neatly.
1713 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1714 Code now saves realname of the user if it becomes available.
1716 * Renamed configure.in to configure.in.pre and made ./prepare
1717 script to automatically add correct version string to
1718 configure.in which it creates from configure.in.pre.
1720 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * NAMES command reply now shows users mode with the nickname when
1725 * Moved silc_client_ch[u]mode[_char] functions from
1726 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1727 place sucks, they are utility functions and should be in some
1730 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1732 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1735 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Added TRQ (efficient deque and list library) into lib/trq. This is
1740 a very good list library that is currently used in the SILC. Defined
1741 SilcList API over the library because I didn't like the API very
1742 much. See lib/trq/silclist.h for the API and examples of how to
1743 use the API. Fixed various places in the code to use the new
1744 SilcList API. The SilcList is meant for lists that has a structure
1745 already defined as a list. It is not suitable to add just some
1746 context to the list (in TRQ, the context is the list actually).
1748 So, I defined SilcDList that can be used for the purpose where
1749 predefined list structure does not exit. This can be used as
1750 such list. Now some context just can be added to the SilcDList.
1751 Currently this list is not used in the SILC just yet, though there
1752 are a lot places where this can replace dynamically allocated
1753 tables and I will fix these places, later, to use SilcDList.
1754 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1755 and use TRQ internally).
1757 Also fixed some annoying warning messages that the original TRQ
1758 code generated. Also minor changes to TRQ's Makefile.in.
1760 * Added support for querying by Client ID to both WHOIS and
1761 IDENTIFY commands into server, as required by the protocol.
1763 * Removed method function pointers from SilcBuffer structure. They
1764 weren't used to anything and just increased the context size for
1765 no good reason. This change also made silc_buffer_alloc and
1766 silc_buffer_free functions inline functions.
1768 * Disabled command flooding detection support until it's fixed so
1769 that it accepts commands in but does not execute them more than once
1772 * Added silc_net_localhost(), to return local hostname, into
1773 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1774 that must be initialized before calling silc_client_init.
1776 * Added new function: silc_server_send_notify_on_channels to send
1777 notify messages to all channels client has joined. It is assured
1778 that the message is sent only once per client.
1780 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1781 lib/silcutil/silcutil.[ch] as silc_format function. The new
1782 function is generic and is used by server as well, not only by
1783 the logging routines.
1785 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1786 the provided version string was not acceptable. Added new function:
1787 silc_ske_check_version into lib/silcske/silcske.h. The function
1788 must be implemented by the application (client or server) and it
1789 does not reside in the SKE library. The function checks the version
1790 string remote end sent.
1792 * Added back pointers (to opaque context and to SilcSocketConnection)
1793 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1795 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1796 duplicate packet context structure.
1798 * Changed `notify' client operation to send same arguments as client
1799 receives from server except for ID's. ID's are mapped to correct
1800 ID entry and that is returned. Also, if channel entry is not sent
1801 by server but the notify is for channel the channel entry is sent
1802 to application (otherwise application doesn't know that it is for
1803 channel (library gets it from packet's Destination ID)).
1805 * Added silc_client_remove_from_channels into client library to
1806 remove a client from all channels it has joined to. Used when
1807 received SIGNOFF notify from server. Added also new function
1808 silc_client_replace_from_channels to replace old ID entry with
1809 new ID entry on all channels. Used when received NICK_CHANGE
1812 * Fixed ID Cache list handling in silc_idlist_get_client in
1813 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1814 to get (or query) client by ID.
1816 * Updated TODO list.
1818 * Added connection authentication status message defined by the
1819 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1820 support for these into the code in client and server side.
1822 * Added generic function silc_client_send_command to send any command
1823 with variable argument list. Application should use this function
1824 to send commands if the command functions provided by the library
1825 does not suite for the application's user interface needs.
1827 * Added new `failure' client operation. Application is notified about
1828 received failure packet if client is executing a protocol. In this
1829 case the protocol's execution has failed.
1831 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1832 is required by the protocol.
1834 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1835 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1838 * Added status flag to SilcSKE object to indicate realtime status
1839 of the SKE protocol.
1841 * Application receives now exactly same command reply arguments as
1842 the library receives from server. However, if ID is received the
1843 corresponding ID entry is returned to the application (eg. Client
1844 ID is mapped to correct SilcClientEntry entry and that is returned).
1845 Changed command_reply client operation due to this change.
1847 * Changed all ID's in commands and in command replys as ID Payloads.
1848 Change affected both client and server side codes.
1850 All ID's sent in SILC network (with execption of ID's in SILC
1851 Packet header) are sent in ID Payload to support variable length
1854 * Server now notifies nick changes and notifies all clients on
1855 the channels about the new nickname (about the new Client ID,
1858 * Implemented CMODE command to change channel modes. Supports all
1859 channel modes defined by the protocol specs except ban and invite
1860 lists. (Also, private channel key mode is supported but support for
1861 setting private channel key in client is missing, thus, this mode
1862 has no effect on client side (except that server requires that the
1863 client uses private channel key and normal channel traffic does not
1866 Also, invite mode works per se, but INVITE command does not work
1867 yet correctly, so you can set channel as invite only channel but
1868 inviting clients to the channel does not work (it is yet to be
1869 thought what's the best way to do it).
1871 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1872 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1873 Implemented CUMODE command to change user's mode on the channel.
1874 Supports all modes defined by the protocol specs.
1876 * Added NAMES command reply to return users modes on the channel.
1878 * Removed unnecessary and slow ciphers from lib/silccrypt.
1880 * Set SO_KEEPALIVE option to connection sockets by default.
1882 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1884 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1885 redefined the Notify Payload into protocol specs.
1887 * Added silc_id_payload_parse_id to get ID directly from raw
1890 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1893 accept searching by Client ID as well.
1895 * Added support for LEAVE and SIGNOFF notify types in client library.
1897 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1898 to parse ID Payload from raw data.
1900 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Added flags parameter into silc_ske_assemble_security_properties
1903 function in lib/silcske/silcske.[ch].
1905 * Changed notify client operation to fit better for notify messages
1906 sent by server. The notify payload received from server is now
1907 passed to the application (after parsing it to SilcNotifyPayload).
1908 It is application's responsibility to retrieve the arguments
1909 from the payload and show the message the way it wants. The message
1910 sent by server is implementation specific.
1912 * Changed public keys to comply with the protocol specification.
1913 Old public keys are not supported anymore and are not compatible.
1915 * Removed nickname from Channel Payload as the latest draft removed
1916 it. The client must resolve the nickname from the NAMES command
1917 reply received when it joined the channel.
1919 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1921 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1923 * Fixed some errors in protocol specification drafts.
1925 * Created lib/silccore/silcnotify.c to implement Notify Payload
1926 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1927 generic payloads described by protocol specifications. The file
1928 includes implementations for ID Payload and Argument Payload.
1930 * Changed Command Payload implementation to use the new Argument
1931 Payload. Changed command_xxxx_payload to command_payload_xxxx
1932 to comply with SILC coding conventions.
1934 * Added suppport for Argument Payload handling in Notify Payload
1935 implementation as protocol requires it. Added the new support
1936 into server and client lib as well.
1938 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Added support for multiple nicknames on same channel. [n] is
1941 added locally to the nickname if there are more than one same
1942 nicknames on the channel.
1944 * Server now sends all nicknames that matched WHOIS request.
1945 Client also shows the list received from server.
1947 * Added TOPIC command to client side. User can now set and show
1948 current topic on channel.
1950 * Added MOTD command to client and server. Also, server sends the
1951 motd when client connects to the server.
1953 * Changed version strings to comply ISO 8601.
1955 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Fixed protocol error handling in client library. It should now
1958 cope even if the SKE fails for some reason.
1960 * Made new protocol specification drafts for submitting to IETF.
1962 * Implemented TOPIC command to server in silcd/command.c.
1964 * Added two new notify types into lib/silccore/silcnotify.h:
1965 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1966 notify nickname change and topic setting/change on a channel.
1968 * API change of command_reply operation in client library. The
1969 application gets now the status type received from server as well.
1971 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1975 * Cras fixed and optimized the packet handling even further and
1976 it should work now. Minor change to the prototype of function
1977 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1979 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Added new function into lib/silcutil/silcschedule.[ch]:
1982 silc_schedule_with_fd to select() a specified fd. The function
1983 returns after timeout expires or data arrives or goes. The
1984 function is used by packet routines to wait that all data is
1985 received from network.
1987 * Fixed data reading from network in lib/silccore/silcpacket.c.
1988 The code now assures that all data is read from the fd and then
1989 continues packet processing. This was a bug fix since the code
1990 used to drop some data in some circumstances.
1992 * Added new function into lib/silcclient/client.[ch]:
1993 silc_client_start_key_exchange to start key exchange after
1994 connection has been established to server. The code internally
1995 now uses this funtion but its main purpose was to provide it
1996 for applications that perform their own connecting. After
1997 application has created a connection it merely calls this
1998 function to start the key exchange between client and server.
1999 The library takes care of everything else after that.
2001 Updated also lib/silcclient/README to explain the usage of
2004 * Do not send to application information that connection has
2005 been established. Application gets notified it by connect
2008 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Applied cras's patch to add silc_schedule_one function. The
2011 function runs scheduler once and returns.
2013 * Fixed the scheduler after cras messed it up. The timeout
2014 handling works now as it's supposed to work.
2016 * Added into lib/silccore/ silcnotify.h to include notify
2017 message types support. Changed silc_server_send_notify*
2018 functions, in server.[ch], to support those new notify types.
2019 Added the support for the notify types into client library,
2020 as well. Added new notify client operation into ops.h in
2023 * Changed silc_server_packet_send_to_channel to send normal
2024 packets instead of just channel message packets. The function
2025 is now used to send the notify packets to channels. It is not
2026 used to send channel message packets anymore, as server never
2029 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2030 va_arg()s as it seems to require it nowadays. I guess, if SILC
2031 is compiled with older va_arg() the new code should work anyway.
2033 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Splitted core library. Core library (lib/silccore) includes
2036 now only SILC protocol specific core (and common) components.
2037 Created new utility library (lib/silcutil) that includes more
2038 generic purpose stuff. The stuff for util library was taken
2039 from the old core library. This was minor and easy split.
2041 * Created SILC Client Library (lib/silcclient) that includes
2042 implementation of the SILC client without user interface. This
2043 was major move from silc/ directory. The code has been changed
2044 so that it is transparent towards the user interface. The
2045 silc/ directory includes now the same user interface as before
2046 and it uses the new client library. Read lib/silcclient/README.
2047 Basicly, the client library performs everything else related
2048 to SILC except user interface handling. Also, configuration
2049 files are considered to be part of user interface and library
2050 does not handle them.
2052 This change also changed a lot of structures, function naming etc.
2053 Most important change was that SilcClientWindow object was
2054 renamed to SilcClientConnection in the client library. Created
2055 also new file lib/silcclient/ops.h. Also added new files
2056 silc/local_command.[ch] and silc/client_ops.[ch].
2058 All these changes were made to make it easier for user interface
2059 designers to create what ever user interface for the SILC client
2062 It is also expected that the server will be moved to lib
2063 directory as well and SILC Server Library will be created;
2064 sometimes in the future.
2066 * Removed Local commands from lib/silccore/silccommand.h as
2067 they are application specific and new client library does not
2068 handle any of those anymore.
2070 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2071 old client implementation in silc/.
2073 * Added support for callback functions in SILC_LOG_* macros.
2074 Application can now set its own callbacks that will be called
2075 instead of using the default functions that will always print
2076 the debug messages to stderr (or stdout). Also, debugging can
2077 now be disabled by setting silc_debug to FALSE and re-enabled by
2078 setting it to TRUE. Note, that logging will still work even
2079 if debugging is disabled.
2081 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2082 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2083 silc_log_reset_debug_callbacks.
2085 * To enable debugging in silc client one must give now -d
2086 option on command line.
2088 * Changed silc_schedule_init to automatically allocate task queues
2089 if they are not allocated before calling it.
2091 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Added GMP 3.1 into math library.
2095 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2098 a channel in SILC network. The packet is used by servers and
2099 routers to notify other routers that user has left a channel.
2100 This little feature was missing until now. Added the feature
2101 to protocol specification as well.
2103 Added functions: silc_server_send_remove_channel_user and
2104 silc_server_remove_channel_user into server.[ch].
2106 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2107 lib/silccore/silcpacket.h. However, they are not implemented
2110 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Fixed joining to a channel and sending channel messages
2113 between server and router. The channel message sending should
2114 now work inside a cell.
2116 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Fixed the private message sending between server and router.
2119 The private message sending should now work inside a cell.
2121 * Added silc_server_replace_id into server.[ch] to replace
2122 existing ID in the SILC network.
2124 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2125 and silc_idlist_replace_server_id into idlist.[ch] in server.
2127 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Fixed the server to server connections. Server can again now
2130 connect to router. Router to router connections probably does
2133 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Added dynamic protocol registering support. Now protocols can
2136 registered and unregistered on the fly. Patch by cras.
2138 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Added lib/contrib directory to hold routines that some platforms
2141 don't have but are needed by SILC.
2143 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2144 into lin/contrib to provide getopt() and getopt_long() for
2145 those who don't have it.
2147 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Added AWAY command to client. When away message is set and
2150 client receives a private message packet the client automatically
2151 replies to the sender with the away message.
2153 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2154 bug seemed to be the cause of recent problems when compiling
2157 * Added version detection support to SKE protocol specification
2158 and added the new changes to the SKE implementation as well.
2159 There were other minor changes in the SKE protocol as well.
2161 Many changes in lib/silcske/silcske.[ch] and in
2162 lib/silcske/payload.[ch].
2164 * Added ^U functionality, clear input line. Patch from cras.
2166 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Mainly small bugfixes on core library. Fixed some debugging
2169 logging and buffer overflow in silclog.c.
2171 * Updated config.sub and config.guess on the distribution tree.
2173 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Added command lagging support in server. Client may execute
2176 commands now only once in two seconds.
2178 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Optimized packet reception. MAC computation and checking is now
2181 also more optimized. A lot previously duplicated code is now
2182 used as generic by both client and server.
2184 * Fixed key pair generation in clientutil.c
2186 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Added into lib/silccore/silcbufutil.[ch] new function;
2189 silc_buffer_realloc.
2191 * Moved generic packet sending/encryption functions to
2192 lib/silccore/silcpacket.[ch] from client and server. Some
2193 rewriting of the functions.
2195 * Moved all generic packet reception/decryption functions to
2196 lib/silccore/silcpacket.[ch] from client and server. The
2197 packet processing is now much cleaner in both client and server.
2198 These were major changes in both client and server.
2200 * Created many common functions in server to do packet sending.
2201 Previously code were duplicated a lot, this has been removed
2204 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Rewrote major parts of the ID cache system. Don't know
2207 whether it is better now or not but at least the API is more
2210 * Major rewrite on ID cache stuff on client because of the ID
2211 cache API changes. Added idlist.c to client.
2213 * Also major rewrite on ID cache stuff on server as well.
2214 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2215 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2216 in hand, instead they are all put into the ID cache system now.
2217 All server_idlist_* routines uses ID cache now instead of
2218 traversing its own lists (those lists does not exist anymore).
2219 SilcIDList though still exists. Also, SilcXXXEntry's are
2222 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Finally made the SKE implementation compliant to the protocol
2225 specification. All mp integers are now binary encoded as
2226 opposed being HEX encoded.
2228 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2231 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2232 functions: silc_[encode/decode]_pem. Also added function
2233 silc_encode_pem_file to PEM encode with newlines ('\n') for
2236 * SILC public keys are now encoded either PEM or binary. Same
2237 option is for private keys as well. By default private keys
2238 are binary encoded and public keys PEM encoded. Silly HEX
2239 encoding were removed.
2241 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2242 function to create fingerprints.
2244 * Fixed a bug in SHA1; does not change the original data anymore.
2246 * Partly implemented INFO command on client and server side.
2247 Fixed CLEAR command. Changes to SERVER command; show current
2248 server(s) when giving command without arguments. Added
2249 VERSION command to client.
2251 * Added check to server that unregistered connections cannot
2252 execute commands (unless it is specificly allowed).
2254 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Fixed screen refresh.
2258 * Fixed channel joining bug from client. On some circumstances
2259 client tried to join to a channel it had already joined.
2261 * Added public key verification process into client's protocol.c.
2262 The client now verifies the public key from user and saves
2263 it into ~./silc/serverkeys/ directory.
2265 Added into: clientutil.[ch]: silc_client_verify_server_key.
2267 * Changed SKE protocol's silc_ske_initiator_finish function
2268 to accept callback function that verifies the received public
2269 key. Removed old silc_ske_verify_public_key function.
2271 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2274 silc_pkcs_private_key[_data]_set.
2276 * Made the password and public authentication more cleaner in
2277 server's protocol.c.
2279 * Removed historic and obsolete protocol `channel_auth' from
2280 both client and server.
2282 * Removed wrong way of sending command status messages from
2283 server to client in server's command.c. The old way violated
2284 protocol specification.
2286 Changes to silccore/silccommand.[ch]: removed
2287 silc_command_encode_status_payload -> not needed anymore,
2288 changed silc_command_encode_payload_va to accept extra
2289 argument on variable argument list. The argument type must
2290 now be provided to the function. Also, added new function:
2291 silc_command_encode_reply_payload_va which is same as
2292 normal command_encode_payload_va except command status type
2293 is provided as extra argument.
2295 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Added ~./silc directory handling. The directory includes the
2298 public and private keys for the client.
2300 Added silc_client_check_silc_dir, silc_client_create_identifier
2301 and silc_client_load_keys.
2303 * Implemented SILC protocol compliant public key. Added public
2304 and private key saving to and loading from files.
2306 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2307 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2308 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2309 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2310 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2312 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2313 silc_pkcs_load_[public/private]_key.
2315 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Added silc_server_get_route (route.[ch]) to get connection
2318 data for the fastest route for given ID.
2320 * Implemented INVITE command on client and server. The command
2321 were re-defined in the SILC Protocol Specification and the
2322 implementation now complies with the specification.
2324 * Implemented PING command on client and server.
2326 * Implemented NAMES command on client and server. The server side
2327 supports currently only normal server not router server yet.
2328 Some changes to NAMES definition in SILC protocol specification.
2330 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Implemented LEAVE command on client and server.
2334 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2335 again. This change was made to the protocol as well. Server
2336 should not violate the protocol specification anymore.
2338 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2341 was tested. SOCKS4 was not but should work anyway.
