1 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented OPER and SILCOPER commands into the server and
6 * Added silc_auth_verify and silc_auth_verify_data to verify
7 the authentication directly from the authentication payload.
8 It supports verifying both passphrase and public key based
9 authentication. Affected file lib/silccore/silcauth.[ch].
11 * Added `hash' field to the SilcIDListData structure. It is the
12 hash negotiated in the SKE protocol. Affected file is
15 * Slight redesigning of the SilcAuthPayload handling routines.
16 Do not send SilcPKCS but SilcPublicKey as argument.
18 * Implemented the public key authentication support to the
19 serverconfig. The public key is loaded fromthe provided path
20 and saved as authentication data to void * pointer. Thus,
21 changed the unsigned char *auth_data to void *auth_data;
23 * Fixed SHUTDOWN command to send the reply before the server
24 is shutdown. :) Affected file silcd/command.c.
26 * Fixed fatal bug in CONNECT command. The hostname was invalid
27 memory and server crashed. Affected file silcd/command.c.
29 * Fixed fatal bug in CLOSE command. The server_entry became
30 invalid but was referenced later in the command. Affected file
33 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Fixed fatal bug in failure packet handling. Server ignored
36 the failure and thus crashed when it came.
40 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
43 that the command may be executed only once in (about) 2 seconds.
44 The old SILC_CF_LAG flag is same but allows command bursts up
45 to five before limiting.
47 Added the support for CF_LAG and CF_LAG_STRICT flags to the
48 server code. Various commands now includes the CF_LAG_STRICT
49 flag to disallow any kind of miss-use of the command.
51 * Fixed the silc_buffer_unformat to not to allocate any data
52 if the length of the data is zero. It used to allocate the
53 length + 1. Affected file lib/silcutil/silcbuffmt.c.
55 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
57 * Changed the format of AdminConnection configuration section
58 in the server. Added username of the admin to the format.
59 Affected files silcd/serverconfig.[ch].
61 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
62 to return admin configuration data by host, username and/or
65 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Implemented WHOWAS command to the server. Added the functions:
69 silc_server_command_whowas_parse,
70 silc_server_command_whowas_send_reply,
71 silc_server_command_whowas_from_client and
72 silc_server_command_whowas_from_server
74 * Added <Client ID> argument to the WHOWAS command reply. Updated
75 the protocol specs accordingly.
77 * Implemented WHOWAS command and command_reply to the client
80 Implemented the WHOWAS printing on the user interface.
82 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
84 * Added new argument to the WHOWAS command reply, the real name.
85 It is an optional argument. Updated the protocol specs.
87 * Added SilcIDCacheDestructor callback that is registered when
88 the SilcIDCache is allocated. The callback is called when
89 an cache entry in the ID Cache expires, or is purged from the
90 cache. Added into lib/silccore/idcache.[ch].
92 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
93 to destruct the client entries when the cache entry expires.
94 Other ID Cache's in server and in the client library ignores
97 * If the ID Cache entry's `expire' field is zero then the entry
98 never expires. Added boolean `expire' argument to the
99 silc_idcache_add function in the lib/silccore/idcache.[ch].
100 If it is TRUE the default expiry value is used.
102 * Added silc_server_free_client_data_timeout that is registered
103 when client disconnects. By default for 5 minutes we preserve
104 the client entry for history - for WHOWAS command.
106 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added support to the server to enforce that commands are not
109 executed more than once in 2 seconds. If server receives
110 commands from client more frequently, timeout is registered
111 to process the commands. Affected file silcd/command.c.
112 Added new function silc_server_command_process_timeout.
114 * Changed NICK_NOTIFY handling in client library to check that
115 if the client's nickname was changed, so there is no need to
116 resolve anything from the server.
118 * Removed error printing from the WHOIS and IDENTIFY commands.
119 If error occurs then it is ignored silently in the client library.
120 The application, however, may map the received error to
121 human readable error string. The application currently maps
122 the NO_SUCH_NICKNAME error to string.
124 * Made the command status message public to the application. Moved
125 them from lib/silcclient/command_reply.c to
126 lib/silcclient/command_reply.h. The application can map the
127 received command status to the string with the
128 silc_client_command_status_message function.
130 * Added check to the server to check that client's ID is same
131 as the Source ID in the packet the client sent. They must
134 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Added dist-bzip hook to the Makefile.am to make bzip2
137 compressed distributions.
139 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Server now enforces the maximum length for the nickname and
142 the channel as protocol specification dictates. 128 bytes for
143 nickname and 256 bytes for channel name.
145 * Moved the WHOIS printing to the application. The client libary
146 does not print out the WHOIS information anymore, the application
147 must do it. Renamed silc_client_command_reply_whois_print to
148 the silc_client_command_reply_whois_save.
150 The client's idle time is also sent to the application now, and
151 the idle is shown on screen.
153 * Added silc_client_command_reply_identify_save to save the
154 received IDENTIFY entries.
156 * Do not check for channel private keys in message sending and
157 reception if the channel does not have the PRIVKEY mode set.
158 Affected file lib/silclient/client_channel.c.
160 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
163 just surfaced after chaning the JOIN procedure.
165 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Added silc_client_get_clients_by_list to get client entries
168 from Client ID list, that is returned for example by JOIN
169 and USERS command replies. The application should use this
170 function for example when JOIN command reply is received to
171 resolve the clients already on the channel (library does not
172 do that anymore as USERS command reply is not used in the JOIN
173 procedure anymore). Affected files lib/silcclient/silcapi.h and
174 lib/silcclient/idlist.c.
176 * JOIN command reply and USERS command reply returns now SilcBuffer
177 pointers instead of unsigned char pointers when returning
178 the client list and mode list.
180 * Added <Client ID> argument to the JOIN command reply, mainly
181 for the server to identify for which client the command was
182 originally sent. Updated protocol specs accordingly.
184 * Added SilcDlist private_key pointer to the SilcChannelEntry
185 in the client to support the channel private keys. Affected
186 file is lib/silcclient/idlist.h.
188 * Added SilcChannelPrivateKey argument to the function
189 silc_client_send_channel_message so that application can choose
190 to use specific private ke if it wants to. If it is not provided,
191 the normal channel key is used, unless private keys are set.
192 In this case the first (key that was added first) is used
193 as the encryption key.
195 * Implemented the support for channel private key handling.
196 Implemented the following functions:
198 silc_client_add_channel_private_key,
199 silc_client_del_channel_private_keys,
200 silc_client_del_channel_private_key,
201 silc_client_list_channel_private_keys and
202 silc_client_free_channel_private_keys
204 Affected file lib/silcclient/client_channel.c.
206 * Added the support for the private keys in the channel message
207 sending and encryption and in the message reception and
208 decryption. Affected funtions are
209 silc_client_send_channel_message and silc_client_channel_message.
211 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Added SKE's key verify callback to the client library's
214 KE protocol context. Affected files lib/silcclient/protocol.[ch].
216 * Removed the statement that server (or router) must send USERS
217 command reply when joining to the channel so that the client
218 knows who are on the channel. Instead, the client list and
219 client's mode list is now sent in the JOIN command reply to the
220 client who joined channel. This is better solution.
222 * Added function silc_server_get_users_on_channel and function
223 silc_server_save_users_on_channel to the silcd/server.[ch].
225 * Removed function silc_server_command_send_users from the
228 * Do not show topic on the client library anymore. The topic is
229 sent in the command reply notify to the application and the
230 application must show the topic now.
232 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
234 * Added client searching by nickname hash into the IDENTIFY and
235 WHOIS commands in the server as they were clearly missing from
236 them. Affected file is silcd/command.c.
238 * Fixed a bug in private message receiving in the client library.
239 The remote ID was freed and it wasn't supposed, now it is
242 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Minor fix to the channel payload; allocate the data area, as it
245 needs to be of specific length.
247 * If the key agreement port is zero then the operating
248 system will define the bound port. Affected files are
249 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
251 * Added new function silc_channel_payload_decrypt into the file
252 lib/silccore/silcchannel.[ch].
254 * Moved the channel message etc, check from silc_packet_decrypt
255 to applications. The library calls now a generic
256 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
257 when the packet is either normal or special. This was done to
258 allow more wide range of checking that was not allowed when
259 the code was in library. Now applications can do virtually any
260 checks to the packet and return to the library the decision how
261 the packet should be processed. Affected files are
262 lib/silccore/silcpacket.[ch].
264 Added silc_server_packet_decrypt_check to the server and
265 silc_client_packet_decrypt_check to the client library.
267 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
268 to send with specified source and destination information.
270 * Channel message delivery between routers was broken after the
271 channel key distribution was fixed earlier. The channel key
272 was used be to distributed to other routers as well which is not
273 allowed by the protocol. Now this is fixed and channel keys
274 really are cell specific and the channel message delivery between
275 routers comply with the protocol specification.
277 * Fixed various commands in server to check also the global list
278 for the channel entry and not just the local list. The affected
279 file silcd/command.c.
281 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Added assert()s to buffer formatting and unformatting routines
284 to assert (if --enable-debug) when error occurs. Affected
285 file: lib/silcutil/silcbuffmt.c.
287 * Changed to auto-reconnect to check whether the remote host is
288 router and register the re-connect timeout if it is. It used
289 to check that whether we are normal server, but router must do
290 auto-reconnect with another router as well. Affected file
293 * Removed the [<key len>] option from CMODE command as the cipher
294 name decides the key length, nowadays. See the defined ciphers
295 from the protocol specification.
297 * Added [<hmac>] option to the CMODE command to define the HMAC
298 for the channel. Added SILC_CMODE_HMAC channel mode.
300 * Added [<hmac>] option for the JOIN command so that user can
301 select which HMAC is used to compute the MACs of the channel
304 * Added Hmac field to the Channel Message Payload. The integrity
305 of plaintext channel messages are now protected by computing
306 MAC of the message and attaching the MAC to the payload. The
307 MAC is encrypted. Now, it is clear that this causes some
308 overhead to the size of the packet but rationale for this is that
309 now the receiver can verify whether the channel message decrypted
310 correctly and also when private keys are set for the channel the
311 receiver can decrypt the packet with several keys and check from
312 the MAC which key decrypted the message correctly.
314 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
315 lib/silccrypt/silccipher.[ch].
317 * Added silc_hash_len to return the digest length into the
318 lib/silcrypt/silchash.[ch].
320 * Rewrote parts of Silc Channel Payload interface in the
321 lib/silccore/silcchannel.[ch]. The encode function now also
322 encrypts the packet and parse function decrypts it.
324 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Fixed a minor formatting bug in the SKE's key material processing.
327 It actually might have processed the keys wrong way resulting
330 * Redefined the mandatory HMAC algorithms and added new algorithms.
331 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
332 and hmac-md5 truncated to 96 bits. The mandatory is now
333 hmac-sha1-96. Rest are optional (including the one that used
334 to be mandatory). Rationale for this is that the truncated HMAC
335 length is sufficient from security point of view and can actually
336 make the attack against the HMAC harder. Also, the truncated
337 HMAC causes less overhead to the packets. See the RFC2104 for
340 * Added new [hmac] configuration section. The SKE used to use
341 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
342 is of course wrong. The official names that must be proposed in
343 the SKE are the ones defined in the protocol specification
344 (hmac-sha1-96 for example). The user can configure any hmac
345 using any hash function configured in the [hash] section. At
346 least, the mandatory must be configured.
348 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
350 * Added HMAC list to the SKE proposal list. It has now both
351 hash algorithm list and HMAC list. This makes the protocol
352 incompatible with previous versions. The SKE now seems to work
353 the way it is supposed to work, for the first time actually.
355 * Defined plain Hash algorithms to the protocol specification.
358 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Implemented support for key agreement packets into the server.
361 Added functions silc_server_key_agreement and
362 silc_server_send_key_agreement. Other than these functions,
363 server has nothing to do with this packet.
365 * Added support for private message key packets into the server.
366 Added functions silc_server_private_message_key and
367 silc_server_send_private_message_key.
371 * Changed the silc_[client|server]_protocol_ke_set_keys to be
372 called in the protocol's final callback instead in the END
373 protocol state. This makes a little more sense and in the same
374 time in client we can use the same protocol routines for normal
375 key exchange and to key agreement packet handling as well.
377 * Added to both client's and server's KE protocol context the
378 SilcSKEKeyMaterial pointer to save the key material. We will
379 bring the key material to the protocol's final callback by doing
380 this. The final callback must free the key material.
382 * Added SKE's packet_send callback into client's KE protocol
383 context so that the caller can choose what packet sending function
384 is used. This way we can use different packet sending when
385 doing normal SKE when doing key agreement packet handling (in
386 the key agreement packet handling we do not want to encrypt
389 * Implemented the responder side of the key agreement routines
390 in the client. The client can now bind to specified port and
391 accept incoming key negotiation. The key material is passed
392 to the application after the protocol is over.
394 * Implemented the processing of incoming Key Agreement packet
395 in the client. Added function silc_client_key_agreement to
398 * Implemented the intiator side of the key agreement routines
399 in the client. The client can now initiate key agreement with
400 another remote client. The key material is passed to the
401 application after the protocol is over.
403 * Created client_keyagr.c to include all the key agreement
406 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
407 SILC_TASK_CALLBACK except that it is not static.
409 * Created client_notify.c and moved the Notify packet handling
410 from the client.[ch] into that file.
412 * Created client_prvmsg.c and moved all private message and
413 private message key routines from the client.[ch] into that file.
415 * Create client_channel.c and moved all channel message and
416 channel private key routines from the client.[ch] into that file.
418 * Changed silc_client_get_client_by_id_resolve to resolve with
419 WHOIS command instead of IDENTIFY command, in the file
420 lib/silclient/idlist.c.
422 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Implemented the SKE's responder side to the Client library.
426 * When FAILURE is received to the protocol do not trust it
427 blindly. Register a timeout to wait whether the remote closes
428 the connection as it should do it, only after that process the
429 actual failure. This was changed to both client and server.
431 * Added client_internal.h to include some of the structures
432 there instead of client.h in lib/silcclient/.
434 * Added function silc_task_unregister_by_callback to unregister
435 timeouts by the callback function.
437 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Some "Incomplete WHOIS info" errors has been appearing on the
440 log files. Took away the entry->userinfo check from WHOIS
441 reply sending. The entry->userinfo is now " " if client did not
442 provide one. I thought this was fixed earlier but something
443 is wrong still. Let's see if the error still appears.
445 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Fixed a minor bug in the login when the channel key is
448 re-generated in the server. It used to generate the key in
449 wrong order and thus caused problems in the channel traffic.
451 * Fixed a minor bug in channel key distsribution after
452 KICK command. The key was not sent to the router even though
455 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
457 * Added silc_ske_process_key_material_data as generic routine
458 to process any key material as the SILC protocol dictates. The
459 function is used by the actual SKE library but can be used by
460 applications as well. This relates to the private message keys
461 and the channel private keys since they must be processed the
462 same way the normal SILC session keys. The protocol dictates
463 this. Affected files: lib/silcske/silcske.[ch].
465 Added also silc_ske_free_key_material to free the
466 SilcSKEKeyMaterial structure.
468 * Defined silc_cipher_set_key function to set the key for
469 cipher without using the object's method function. The affected
470 files: lib/silccrypt/silccipher.[ch].
472 * Implemented silc silc_client_add_private_message_key,
473 silc_client_add_private_message_key_ske,
474 silc_client_del_private_message_key,
475 silc_client_list_private_message_keys and
476 silc_client_free_private_message_keys functions in the
479 Added functions silc_client_send_private_message_key to send
480 the Private Message Key payload and silc_client_private_message_key
481 to handle incoming Private Message Key payload.
483 * Added Cipher field to the Private Message Key payload to set
484 the cipher to be used. If ignored, the default cipher defined
485 in the SILC protocol (aes-256-cbc) is used.
487 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Removed lib/silcclient/ops.h file.
491 Redefined parts of the SILC Client Library API. Created new
492 file silcapi.h that deprecates the ops.h file and defines the
493 published Client Library API. Defined also private message key
494 API and channel private key API into the file.
496 This is the file that the application must include from the
497 SILC Client Library. Other files need not be included by
498 the application anymore.
500 * Added new key_agreement client operation callback and also
501 defined the Key Agreement library API for the application.
503 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
506 is used by clients to request key negotiation between another
507 client in the SILC network. If the negotiation is started it
508 is performed using the SKE protocol. The result of the
509 negotiation, the secret key material, can be used for example
510 as private message key.
512 Implemented the Key Agreement payload into the files
513 lib/silccore/silauth.[ch].
515 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Redefined ciphers for the SILC protocol. Added some new ciphers
518 and defined the key lengths for the algorithms. Changed the
519 code accordingly. The default key length is now 256 bits.
521 * Fixed SKE key distribution function silc_ske_process_key_material
522 when the key length is more than 128 bits. The default key
523 length in SILC is now 256 bits.
525 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
526 to indicate unsupported algorithm.
528 * Renamed rijndael.c to aes.c and all functions as well.
530 * Fixed a long standing channel key setting bug in client library.
531 Weird that it has never surfaced before.
533 * Fixed bug in channel deletion. If the entire channel is removed
534 then it must also delete the references of the channel entry
535 from the client's channel list as the client's channel entry and
536 the channel's client entry share same memory.
538 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Implemented CONNECT and SHUTDOWN commands in the client.
542 * Implemented CLOSE command to the client.
544 * Added the function silc_idlist_find_server_by_name into the
545 files silcd/idlist.[ch].
547 Added the function silc_idlist_find_server_by_conn into the
548 files silcd/idlist.[ch].
550 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * DIE command was renamed to SHUTDOWN. Updated the both code
555 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
556 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
558 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
561 * Added function silc_server_create_connection function to create
562 connection to remote router. My server implementation actually
563 does not allow router to connect to normal server (it expects
564 that normal server always initiates the connection to the router)
565 so the CONNECT command is only good for connecting to another
568 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
571 or some other client was kicked from the channel.
573 Implemented the handling of the notify type to both client
576 Implemented silc_server_send_notify_kicked to send the KICKED
577 notify. It is used to send it to the server's primary router.
579 * Implemented the KICK command into server and client.
581 * Added `query' argument to the silc_idlist_get_client function
582 to indicate whether to query the client from server or not if
585 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
586 to indicate that the client is not channel founder.
590 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Removed the rng context from SilcPacketContext structure and
593 changed that the packet routine uses the Global RNG API.
595 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Added support for quit message that client can "leave" on the
598 channel when it quits the SILC. It is ditributed inside the
599 SILC_NOTIFY_TYPE_SIGNOFF notify type.
601 Added silc_server_free_client_data that will take the
602 signoff message as argument.
604 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
606 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Updated parts of the protocol specification to keep it up
611 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
613 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
614 payloads in one packet.
616 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
617 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
618 use now the new List flag.
620 * Also deprecated the following packet types: REPLACE_ID,
621 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
623 * Added list support for Notify packet in server.
625 * Added silc_server_send_notify_channel_change to send the
626 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
627 the silc_server_send_replace_id.
629 * Added silc_server_send_notify_nick_change to send the
630 NICK_CHANGE notify type. Deprecates the function
631 silc_server_send_replace_id.
633 * Added silc_server_send_notify_join to send the JOIN notify type.
634 Deprecates the function silc_server_send_new_channel_user.
636 * Added silc_server_send_notify_leave to send LEAVE notify type.
637 Deprecates the function silc_server_send_remove_channel_user.
639 * Added silc_server_send_notify_cmode and
640 silc_server_send_notify_cumode to send CMODE and CUMODE notify
641 types. Deprecates the silc_server_send_set_mode function.
643 * Added SERVER_SIGNOFF notify type to indicate that server has
644 quit. This means that all clients on the channel from that
645 server will drop. This can be also used when netsplit happens.
647 Deprecated REMOVE_ID packet type since it is not needed anymore
650 Added silc_server_send_notify_server_signoff to send the
651 SERVER_SIGNOFF notify type. Deprecates the function
652 silc_server_send_remove_id.
654 Added also silc_server_send_notify_signoff to send the
657 * Employed the PKCS #1. It is the mandatory way to do RSA in the
658 SILC protocol from this day on. Changed the protocol
659 specification as well.
661 * Added silc_server_send_notify_topic_set to send TOPIC_SET
662 notify type. It is used between routers to notify about
663 topic changes on a channel.
665 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
668 * Partly updated the protocol specification to comply with the
669 changes now made. It is still though a bit outdated.
671 * The JOIN notify type now takes one extra argument <Channel ID>.
672 The packet used to be destined to the channel but now the
673 JOIN type may be sent as list thus it is impossible to
674 destine it to any specific channel. By adding this argument
675 it is again possible.
677 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Added CREDITS file. The CHANGES and CREDITS file will appear
680 in the distribution as well.
682 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
685 types in the server's silcd/packet_receive.c.
687 * Implemented CMODE and CUMODE to work in router environment.
689 * Fixed minor encoding and decoding buglet from the
690 lib/silccore/silcmode.c.
692 * Fixed buffer overflow from lib/silcclient/command.c in USERS
695 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
697 * Changed all SilcConfigServer* and silc_config_server* to
698 SilcServerConfig* and silc_server_config*, respectively.
701 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Associated the ID (client or server ID) to the Authentication
704 Payload to avoid any possibility of forging. Updated the
705 protocol specification and the code accordingly.
707 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * The RSA key length is now save to the RsaKey context in the
710 key generation process in lib/silccrypt/rsa.c. The key length
711 is now used to figure out the maximum size of the block allowed
712 to be encrypted/signed.
714 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
715 is equivalent to the silc_mp_mp2bin but does not allocate any
718 * Changed silc_mp_mp2bin API to take length argument. If it is
719 non-zero then the buffer is allocated that large. If zero, then
720 the size is approximated using silc_mp_sizeinbase, which however
723 * Created Global RNG API which is global RNG that application can
724 initialize. After initializing, any routine anywhere in the
725 code (including library) can use RNG without allocating a new
726 RNG object. This was done to allow this sort of use of the
727 RNG in code that has no chance to allocate RNG object. All
728 applications currently allocate this and many routines in the
729 library use this. Affected file lib/silccrypt/silcrng.[ch].
731 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
732 it to use the Global RNG API.
734 * Defined Authentication Payload into protocol specification that
735 is used during SILC session to authenticate entities. It is
736 used for example by client to authenticate itself to the server
737 to obtain server operator privileges.
739 Implemented this payload into the lib/silccore/silcauth.[ch].
740 Implemented also routines for public key based authentication
741 as the new protocol specification dictates.
743 Moved definitions of different authentication methods from
744 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
746 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
747 silc_pkcs_verify and silc_pkcs_sign_with_hash and
748 silc_pkcs_verify_with_hash functions into the file
749 lib/silccrypt/silcpkcs.[ch].
751 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * The client entry's userinfo pointer must be always valid.
754 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
755 will fail since it requires the userinfo. Now, the userinfo
756 is allocated as "" if actual userinfo does not exist. Actually,
757 it must exist and it is totally Ok to drop client connections
758 that does not announce the userinfo. However, we will make
759 this workaround for now.
761 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
762 to return the remote port by socket.
764 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
767 SILC_SERVER_PENDING_EXEC and added an new macro
768 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
769 data or when error occurs while processing the pending command.
771 Added new argument `destructor' into silc_server_command_pending
772 and to the SilcServerCommandPending object. This destructor is
773 now called after calling the pending callback or if error occurs
774 immediately. If error occurs the actual pending callback won't
775 be called at all - only the destructor. The destructor may be
776 NULL if destructor is not needed.
778 All this applies for client library code as well. Similar
779 changes were made there as well for the pending commands.
781 In the client, the application must now allocate the
782 SilcClientCommandContext with the silc_client_command_alloc
785 * Added reference counter to the SilcServerCommandContext. Added
786 function silc_server_command_alloc and silc_server_command_dup
789 Same type of functions added to the client library for the same
792 * Removed the cmd_ident from IDListData away since it is now
793 global for all connections. It is the command identifier used
794 in command sending and with pending commands. The affected file
797 * Added reference counter to the SilcSocketConnection objecet to
798 indicate the usage count of the object. The object won't be
799 freed untill the reference counter hits zero. Currently only
800 server uses this, and client ignores it. The client must be
801 set to use this too later. The affected files are
802 lib/silccore/silcsockconn.[ch]. Added also the function
803 silc_socket_dup to increase the reference counter.
805 This was mainly added because it is possible that the socket
806 is removed underneath of pending command or other async
807 operation. Now it won't be free'd and proper DISCONNECTING
808 flags, etc. can be set to avoid sending data to connection that
809 is not valid anymore.
811 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
812 the connection. After that it sets SILC_SET_DISCONNECTED.
813 It is, however, possible that the socket data is not still freed.
814 The silc_server_packet_process now checks that data is not
815 read or written to connection that is DISCONNECTED. The socket
816 get's freed when the reference counter hits zero.
818 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Changed the client operation API: channel_message operation's
821 `sender' is now the client entry of the sender, not the nickname
822 and the `channel' is the channel entry, not the channel name.
824 In the private_message operation the `sender' is now also the
825 client entry of the sender not the nickname.
827 Affected file is lib/silcclient/ops.h and all applications
828 using the client operations.
830 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Moved the calling of ops->connect() from connect_to_server_final
833 into receive_new_id functin since that is the point when the
834 client is actually allowed to send traffic to network. The
835 affected file is lib/silcclient/client.c.
837 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
840 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
841 (if needs broadcasting) instead of broadcasting the packets one
842 by one which would make a burst in the network traffic.
844 * Added `broadcast' argument to the functions in silcd/server.[ch]
845 silc_server_create_new_channel[_with_id] to indicate whether
846 to send New Channel packet to primary router.
848 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Added new function into the silcd/server.[ch] files:
851 silc_server_create_new_channel_with_id to create new channel with
852 already existing Channel ID.
854 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
855 lib/silccore/silcpacket.h. This packet is used t send list of
856 Set Mode payloads inside one packet. Server uses this to set
857 the modes for the channels and clients on those channels, that it
858 announced to the router when it connected to it. The protocol
859 specification has been updated accordingly.
861 * The silc_server_new_channel did not handle the packet coming
862 from normal server as it normally does not send that. However,
863 when it announces its channels it does send it. Implemented
864 the support for that.
866 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
867 into the file lib/silccore/id.h.
869 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Fixed memory leaks in the functions silc_idlist_del_client,
872 silc_idlist_del_channel and silc_idlist_del_server in the file
873 silcd/idlist.c. All of those leaked like a sieve.
875 * Fixed some small memory leaks in the client's function
876 silc_client_notify_by_server.
878 * Added functions into silcd/server.c: silc_server_announce_clients,
879 silc_server_announce_channels and silc_server_announce_server.
880 These functions are used by normal and router server to announce
881 to its primary router about clients, channels and servers (when
882 router) that we own. This is done after we've connected to the
885 These functions effectively implements the following packet types:
886 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
887 and SILC_PACKET_NEW_ID_LIST.
889 * Added new functions into the silcd/packet_receive.[ch]:
890 silc_server_new_id_list, silc_server_new_channel_list and
891 silc_server_new_channel_user_list to handle the incoming
892 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
894 * Added support of changing Channel ID in the function
895 silc_server_replace_id. If the server that announces a channel
896 to the router already exists in the router (with same name but
897 with different Channel ID), router is responsible to send
898 Replace ID packet to the server and force the server to change
899 the Channel ID to the one router has.
901 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
902 client that the Channel ID has been changed by the router. The
903 normal server sends this to the client. Client must start using
904 the new Channel ID as the channel's ID.
906 Implemented handling of this new type into lib/silcclient/client.c
907 into the function silc_client_notify_by_server.
909 * Added new function silc_idlist_replace_channel_id into the files
910 silcd/idlist.[ch] to replace the Channel ID.
912 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Call silc_server_command_identify_check always when processing
915 the IDENTIFY command in silcd/command.c
917 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
920 send keepalive packets. The packet can be sent by clients,
923 Added function silc_socket_set_heartbeat into the file
924 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
925 If not set, the heartbeat is not performed. The actual
926 heartbeat is implemented in the low level socket connection
927 library. However, application is responsible of actually
930 Added silc_server_send_heartbeat to send the actual heartbeat
931 packet into silcd/packet_send.[ch]. Server now performs
932 keepalive with all connections.
934 * Added silc_task_get_first function into lib/silcutil/silctask.c
935 to return the timeout task with shortest timeout. There was a bug
936 in task unregistration that caused problems. TODO has been
937 updated to include that task system must be rewritten.
939 * The client library will now resolve the client information when
940 receiving JOIN notify from server for client that we know but
941 have incomplete information.
943 * Rewrote parts of silc_server_remove_from_channels and
944 silc_server_remove_from_one_channel as they did not remove the
945 channel in some circumstances even though they should've.
947 * Encryption problem encountered in server:
949 The LEAVE command used to send the Channel Key packet to the
950 router immediately after generating it. However, the code
951 had earlier sent Remove Channel user packet but not immediately,
952 ie. it was put to queue. The order of packets in the router
953 was that Channel Key packet was first and Remove Channel User
954 packet was second, even though they were encrypted in the
955 reverse order. For this reason, MAC check failed. Now, this
956 is fixed by not sending the Channel Key packet immediately but
957 putting it to queue. However, this is more fundamental problem:
958 packets that are in queue should actually not be encrypted
959 because packets that are sent immediately gets encrypted
960 actually with wrong IV (and thus MAC check fails). So, packets
961 that are in queue should be encrypted when they are sent to
962 the wire and not when they put to the queue.
964 However, the problem is that the current system has not been
965 designed to work that way. Instead, the packet is encrypted
966 as soon as possible and left to the queue. The queue is then
967 just purged into wire. There won't be any fixes for this
968 any time soon. So, the current semantic for packet sending
971 o If you send packet to remote host and do not force the send
972 (the packet will be in queue) then all subsequent packets to the
973 same remote host must also be put to the queue. Only after the
974 queue has been purged is it safe again to force the packet
977 o If you send all packets immediately then it safe to send
978 any of subsequent packets through the queue, however, after
979 the first packet is put to queue then any subsequent packets
980 must also be put to the queue.
982 Follow these rules and everything works fine.
984 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Added new function silc_server_remove_clients_by_server to
987 remove all client entries from ID list when the server connection
988 is lost. In this case it is also important to invalidate all
989 client entires as they hold the invalid server entry. This
990 fixes fatal bug when server has lost connection and will reconnect
993 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Made some sanity checks to silc_server_daemonise like to check
996 whether the requested user and group actually exists.
998 * Added sanity check to SKE's silc_ske_responder_finish to check
999 that the public and private key actually is valid.
1001 * Invalidate the client's nickname when receiving Replace ID
1002 packet and the Client ID is being replaced. This means that the
1003 server will query the nickname if someone needs it (client)
1006 * Sort the ID Cache in client library when the ID Cache data
1007 has changed (needs sorting).
1009 * Do not allow for SILC client to create several connections to
1010 several servers. The client does not support windows right now
1011 and generating multiple connections causes weird behaviour.
1013 Irssi-silc client does support windows and can handle several
1014 connections without problems, see: www.irssi.org and SILC plugin.
1016 * Fixed some places where client was added to the IDList. The
1017 rule of thumb is following (in order to get everything right):
1018 If the client is directly connected local client then the
1019 `connection' argument must be set and `router' argument must be
1020 NULL to silc_idlist_add_client function. If the client is not
1021 directly connected client then the `router' argument must
1022 bet set and the `connection' argument must be NULL to the
1023 silc_idlist_add_client function.
1025 * The funtion silc_server_packet_send_local_channel actually did
1026 not check whether the client was locally connected or not. It
1027 does that now. Fixed a bug related to LEAVE command.
1029 * Fixed Remove Channel User payload parsing bug in server's
1030 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1032 * The server's silc_server_save_channel_key now checks also the
1033 global ID list for the channel as it might not be in the local
1034 list. Fixed a bug related to LEAVE command.
1036 * Is this the end of the [<unknown>] buglet that has been lurking
1037 around for a long time? A little for loop fix in server's
1038 silc_server_command_whois_parse that is used by both IDENTIFY
1039 and WHOIS command. At least, this was a clear bug and a cause
1040 of one type of [<unknown>] buglet.
1042 * WHOIS and IDENTIFY commands call the function
1043 silc_server_command_[whois/identify]_check function even if
1044 we are not router server.
1046 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Added --with-gmp configuration option. If set the GMP
1049 is always compiled in the SILC source tree. If not set then
1050 it is checked whether the system has the GMP3 installed. If
1051 it has then the GMP won't be compiled (the system's headers
1052 and library is used), if it doesn't have it then the GMP is
1053 compiled in the SILC source tree.
1055 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Changed RSA private exponent generation to what PKCS #1
1058 suggests. We try to find the smallest possible d by doing
1059 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1060 not security fix but optimization.
1062 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Added new config entry [Identity] to fork the server and run
1065 it as specific user and group. A patch from Bostik.
1067 * Imported Dotconf configuration library into lib/dotconf.
1068 This will be used to create the SILC configuration files later.
1069 It will appear in the distsribution after this commit.
1071 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * A big code auditing weekend happening. Auditing code for
1074 obvious mistakes, bugs and errors. Also, removing any code
1077 Removed files for being obsolete:
1079 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1080 inline in the file lib/silcutil/silcbuffer.h)
1082 o lib/silcutil/silcbufutil.c (the header has inline versions)
1084 Changed code to fix possible error conditions:
1086 o The buffer formatting routines now check that the destination
1087 buffer really has enough space to add the data. This applies for
1088 both buffer formatting and unformatting
1089 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1090 unformatting was changed to accomodate following rules:
1091 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1092 sent to the function while XXX_*STRING will not allocate or copy
1093 the data into the buffer. Instead it sets the pointer from the
1094 buffer into the pointer sent as argument (XXX_*STRING used to
1095 require that the pointer must be allocated already). This change
1096 makes this whole thing a bit more consistent and more optimized
1097 (note that the data returned in the unformatting with XXX_*STRING
1098 must not be freed now). The routines return now -1 on error.
1100 o Tried to find all code that use buffer_format and buffer_unformat
1101 and added return value checking to prevent formatting and
1102 especially unformatting errors and possible subsequent fatal
1105 o Changed ske->x and ske->KEY to mallocated pointers in
1106 lib/silcske/silcske.h. Fixed possible data and memory leak.
1108 o Added return value checking to all *_parse* functions. Fixed
1109 many memory leaks as well.
1111 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1112 so that buffer overflows would not happen. All code now also
1113 checks the return value as it can fail.
1115 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added reconnection support to server if the normal server looses
1118 its connection to the router (for example if router is rebooted).
1119 The server performs normal reconnection strategy implemented
1120 to the server. Affected file silcd/server.c.
1122 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Added new packet type SILC_PACKET_SET_MODE that is used to
1125 distribute the information about changed modes (for clients,
1126 channels and clients channel modes) to all routers in the
1127 network. Updated the protocol specification accordingly.
1129 Added functions into silcd/packet_send.c and
1130 silcd/packet_receive.c: silc_server_send_set_mode,
1131 silc_server_set_mode.
1133 Added new files silcmode.[ch] into lib/silccore that implements
1134 the encoding and decoding of Set Mode Payload. Added new type
1135 SilcSetModePayload. Moved the definitions of different modes
1136 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1138 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Oops, a little mistake in server's connection authentication
1141 protocol. The protocol is not ended with FAILURE but with
1142 SUCCESS if the authentication is Ok. :) Affected file is
1145 * Implemented NICK_CHANGE notify handling in server in the file
1146 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1147 the local clients on the channel. After the changing nickname
1148 in router environment snhould work and the [<unknown>] nickname
1149 should appear no more.
1151 The silc_server_replace_id function that receives the Replace ID
1152 payload now sends the NICK_CHANGE notify type also in the file
1153 silcd/packet_receive.c
1155 * Changed WHOIS and IDENTIFY command to support the maximum amount
1156 of arguments defined in protocol specs (3328 arguments). This
1157 fixed a bug that caused problems when there were more than three
1160 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Added extra parameter, command identifier, to the
1163 silc_client_send_command so that explicit command identifier
1166 Changed that ID list routines uses specific command identifier
1167 when sending WHOIS/IDENTIFY requests to the server so that they
1168 can be identified when the reply comes back.
1170 Affected files lib/silcclient/command.[ch],
1171 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1173 * Added `sender' argument to silc_server_packet_send_to_channel
1174 to indicaet the sender who originally sent the packet to us
1175 that we are now re-sending. Ignored if NULL. Affected file
1176 silcd/packet_send.[ch].
1178 * Added some server statistics support in silcd/server_internal.h
1179 SilcServerStatistics structure and around the server code. Also
1180 send some nice statistics information when client is connecting
1183 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Fixed channel ID decoding in server's JOIN command reply in
1186 silcd/command_reply.c
1188 * Fixed braodcasting of replace ID payload to not to send it if
1189 we are standalone server in silcd/packet_receive.c.
1191 * Fixed all channel message sending routines to not to send
1192 packets to clients that has router set, since they are routed
1193 separately in the same function earlier. Affects file
1194 silcd/packet_send.c and all channel packet sending functions.
1196 * In USERS reply, res_argv[i] are not allocated, the table
1197 is allocated. Thus changed that free the table, not its
1200 * In server's whois_check and identify_check if the client is
1201 locally connected do not send any WHOIS commands - they are not
1204 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Fixed some minor bugs in client when sending WHOIS command. The
1207 arguments was in wrong order.
1209 * Removed statis function add_to_channel from server in
1210 silcd/command.c that was previously used with the joining but
1213 * Tested USERS command in router environment successfully with two
1214 routers, two servers and two clients.
1216 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Reorganized the USERS command and command reply in client library
1219 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1220 When the command is given by user we register a pending command
1221 callback that will reprocess the command after the reply has been
1222 received from the server. When reprocessing the packet we then
1223 display the information. Thus, the USERS information is displayed
1224 now in the command callback instead of in the command reply
1225 callback. The processing of the command is same as previously
1226 when server has sent the command reply in the JOINing process.
1228 * Added to USERS command in silcd/command_reply.c to join the client,
1229 we didn't use to know about, to the channel after we've created
1230 a client entry for it. Also, for clienet we did know already still
1231 check whether it is on the channel or not and add it if not.
1233 * Removed silc_server_command_join_notify as the function and its
1236 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Changed the client's pending command handling to the same as the
1239 server's pending command handling. It is also now possible to
1240 execute command reply functions from other command reply
1241 function as the function callbacks for commands and command
1242 replies are one and same. The pending commands are not static
1243 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1244 in client connection context. Thus, pending commands are server
1245 connection specific as it is convenient.
1247 Changed the function silc_client_command_pending and
1248 silc_client_command_pending_del and added new function
1249 silc_client_command_pending_check. Removed the
1250 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1253 * Added cmd_ident, current command identifier, to the client
1254 connection context in lib/silcclient/client.h to keep track on
1255 command identifiers used in command sending. Client's command reply
1256 function handling now supports the mandatory command identifiers.
1258 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1259 funtions in client to fully support pending command callbacks.
1261 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1262 as one of the arguments to the application in the command reply
1265 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1266 before first releasing SILC but came back. Now it is removed again
1267 and should come back nomore. The FORWARDED flag was used only
1268 by the JOINing procedure by forwarding the command packet to router.
1269 Now, the JOINing procedure has been changed to more generic (due
1270 to various router environment issues) and FORWARDED is not needed
1271 anymore for anything. The protocol specification is yet to be
1274 Now, removed silc_server_packet_forward from server and the flag
1275 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1277 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Renamed NAMES command to USERS command. The NAMES was named that
1280 due to historical reasons. Now it is renamed. Also, rewrote
1281 parts of the USERS command. The nickname list is not sent anymore
1282 by the server. Only Client ID and mode lists are sent in the USERS
1283 command. Changed this also to the protocol specification.
1285 The client now resolves the names and stuff after it receives
1286 the USERS list from the server when joining to the channel.
1288 * WHOIS and IDENTIFY commands has been changed to support multiple
1289 Client ID's per command. One can now search for multiple users
1290 in the network by sending only one WHOIS or IDENTIFY command.
1291 Changed the code and the protocol specifications.
1293 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1294 uses silc_server_command_whois_parse to parse the request. */
1296 * If normal server, do not parse the WHOIS and IDENTIFY requests
1297 before sending it to the router. Saves some time.
1299 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Fixed JOIN command on client library. Wrong number of arguments
1302 used to crash the client.
1304 * Added silc_server_channel_has_global function to check whether
1305 channel has global users or not.
1307 * Added silc_server_channel_has_local function to check whether channel
1308 has locally connected clients on the channel.
1310 * The silc_server_remove_from_one_channel now checks whether the
1311 channel has global users or not after given client was removed from
1312 the channel. It also checks whether the channel has local clients
1313 on the channel anymore. If it does not have then the channel entry
1314 is removed as it is not needed anymore.
1316 * The silc_server_notify now checks on JOIN notify whether the joining
1317 client is one of locally connected or global. If it is global then
1318 the channel has now global users on the channel and that is marked
1319 to the channel entry. Also, it now saves the global client to
1320 global list who is joining and JOINs it to the channel. This is
1321 for normal server, that is.
1323 Changed silc_server_send_notify_on_channel,
1324 silc_server_packet_relay_to_channel and
1325 silc_server_packet_send_to_channel check if we are normal server
1326 and client has router set (ie. global client) do not send the
1327 message to that client, as it is already routed to our router.
1329 * Implemented LEAVE notify type handling in silc_server_notify
1332 * Tested LEAVE command in router environment successfully. Tested
1333 with two routers, two servers and two clients.
1337 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1339 * Implemented SIGNOFF notify type handling in silc_server_notify
1342 * silc_server_remove_id now removes the client entry from all channels
1343 it has joined and thusly sends SIGNOFF notify type.
1345 * Rewrote the NAMES list generation in server by removing two excess
1346 loops. The lists are created now inside one loop.
1348 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * silc_server_remove_channel_user checks now also global list
1351 for channel and client.
1353 * silc_server_new_channel_user checks now both local and global
1354 list for channel and client. Fixed a bug in client id decoding.
1355 Used to decode wrong buffer.
1357 * silc_server_channel_message checks now both local and global
1358 list for channel entry.
1360 * Tested channel joining (hence JOIN) in router environment
1361 successfully. Tested with two routers, two servers and two
1364 * Tested channel message sending in router environment successfully.
1366 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Added silc_server_save_channel_key into server.[ch] to save the
1369 received channel key in Channel Key payload processing. It is
1370 also used in JOIN command reply handling.
1372 Equivalent function silc_client_save_channel_key added into
1373 client.[ch] into client library.
1375 * Changed JOIN command reply to send information whether the channel
1376 was created or not (is existing already) and the channel key
1377 payload. Changed protocol specs accordingly.
1379 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1380 the request was sent by ID and not by nickname. Crashed on
1383 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1386 now correctly save the received data.
1388 * silc_server_free_sock_user_data now notifies routers in the
1389 network about entities leaving the network.
1391 At the same time implemented functions silc_server_remove_id
1392 and silc_server_send_remove_id to receive and send REMOVE_ID
1393 packets. The packet is used to notify routers in the network
1394 about leaving entities. The ID removed will become invalid in
1397 * Added function silc_idlist_del_server into server. Removes and
1398 free's server entry from ID list.
1400 * silc_server_private_message function now checks, if we are router,
1401 that the destination ID really is valid ID, naturally.
1403 * In router when NEW_ID packet is received (for new client) the
1404 hash of the Client ID is saved in the ID Cache but the
1405 client->nickname is set to NULL, instead of putting the hash
1408 IDENTIFY command now also checks that client->nickname must be
1409 valid. If it is not if will request the data from the server who
1410 owns the client. Added new function
1411 silc_server_command_identify_check.
1413 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1414 to set the command to already allocated Command Payload.
1416 * Tested private message sending in router environment with two
1417 routers, two servers and two clients. Fixed minor bugs and now
1420 * Fixed segfault from client's NAMES command. Used to crash if
1423 * Forwarded packets must not be routed even if it is not destined
1424 to the receiver. Changed server code comply with this.
1426 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Added `require_reverse_mapping' boolean value to ServerParams
1429 structure. If TRUE (not default) the server will require that
1430 the connecting host has fully qualified domain name.
1432 If the reverse mapping is not required and hostname could not be
1433 found the IP address is used as hostname.
1435 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Implemented version string checking to both client and server.
1438 The check is incomplete currently due to the abnormal version
1439 strings used in development version of SILC.
1441 * Changed all command functions in server to use the new
1444 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Changed char *data to unsigned char *data in ID Cache system to
1447 support binary data as ID Cache data. Changed code to support
1448 binary data in lib/silccore/idcache.c.
1450 * Renamed silc_server_packet_relay_command_reply to
1451 silc_server_command_reply as it is normal packet receiving
1452 function. Rewrote the function to accept command replys for
1453 servers and not only for clients.
1455 * Mark remote router always as registered server if we are connecting
1456 to it. Otherwise, commands sent by the router to us are ignored.
1458 * All ID List find routines now returns the ID Cache Entry pointer
1459 as well if requested.
1461 * WHOIS command works now in router environment, tested with two
1462 routers, two servers and two clients.
1464 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1465 in router environment (as it is almost equivalent to WHOIS) but
1466 hasn't been tested thoroughly. Added new functions:
1468 silc_server_command_identify_parse
1469 silc_server_command_identify_send_reply
1470 silc_server_command_identify_from_client
1471 silc_server_command_identify_from_server
1473 * Disabled route cache adding because adding two different ID's with
1474 same IP replaces the old cache entry thus giving wrong route.
1475 The entry->router->connection is always the fastest route anyway
1476 so route cache may not be needed. Of course, new routes maybe
1477 established after receiving the ID when the entry->router->connection
1478 might not be anymore the most optimal.
1480 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Add route cache for received ID for fast routing.
1484 * Added silc_server_packet_route to route received packet on router
1485 that is not destined to us.
1487 * Renamed silc_server_get_route to silc_server_route_get.
1489 * Added id_string and id_string_len fields into SilcServer to
1490 include encoded ServerID for fast comparing without excess
1491 encoding of the ID's.
1493 * Cleaned up WHOIS command on server side. Added following static
1496 silc_server_command_whois_parse
1497 silc_server_command_whois_check
1498 silc_server_command_whois_send_reply
1499 silc_server_command_whois_from_client
1500 silc_server_command_whois_from_server
1502 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1503 arguments in command replies. All command functions should be
1504 updated to use this macro.
1506 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Minor typo fixes on command reply handling on server.
1510 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * Added silc_server_command_add_to_channel internal routine to add
1513 the client to the channel after router has created the channel and
1514 sent command reply to the server.
1516 * Added generic silc_server_send_command to send any command from
1519 * Use static buffer with ID rendering instead of duplicating data.
1521 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Fixed a channel user mode bug when joining to a channel server gave
1524 everybody channel founder rights, oops.
1526 * We mark ourselves as the router of the incoming server connection
1527 if we are router ourselves. This way we can check in some packet
1528 sending functions whether it is locally connected server. For
1529 incoming router connections we put NULL.
1531 * For router sending packets locally means now always sending the
1532 packet cell wide; to local clients and local servers. For normal
1533 server sending packet locally means sending it to only local
1536 * Fixed the JOIN command to really work in router environment. If the
1537 channel is created it is always created by the router. Router is
1538 also responsible of making the initial joining to the channel,
1539 sending JOIN notify to the sending server and distributing
1540 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1541 does not exist server doesn't do anything else but forward the
1542 command to the router which performs everything.
1544 * Added silc_server_send_channel_key function to send the Channel Key
1547 * Added silc_server_create_channel_key to create new channel key. The
1548 channel key is now re-generated everytime someone joins or leaves
1549 a channel, as protocol dictates. Note: channel->key_len is the
1552 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1555 packet_receive.[ch] to separate packet sending and receiving
1556 routines. The server.[ch] now includes everything else including
1557 actual packet processing (writing and reading data) and other
1560 Renamed silc_server_private_message_send_internal to
1561 silc_server_send_private_message. The routine is still though
1562 used only to relay private messages as server does not send
1563 private messages itself.
1565 Renamed silc_server_new_channel to silc_server_create_new_channel
1566 and added new function sicl_server_new_channel that handles the
1567 incoming New Channel packet. Added also new sending function
1568 silc_server_send_new_channel to send New Channel Payload.
1570 * Added new function silc_server_notify to process incoming notify
1571 packet to the server/router. Server may then relay the notify
1572 to clients if needed.
1574 * Added new function silc_server_new_channel_user to process incoming
1575 New Channel User packet. Router will redistribute the packet and
1576 send JOIN notify to its local clients and locally connected servers
1577 if needed. Normal server will send JOIN notify to its local client
1578 on same channel when received this packet. Added also corresponding
1579 sending function silc_server_send_new_channel_user to sent the
1582 * Added boolean route argument to send_notif_to_channel and
1583 packet_send_to_channel functions to attempt to route the packet
1584 if it is TRUE and send only locally if it is FALSE.
1586 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * silc_server_replace_id now broadcasts the received replace ID
1589 packet if it is not broadcast packet already. The router must
1590 broadcast to inform other routers about changed ID.
1592 * Added backpointer to server's router into SilcServer context in
1593 silcd/server_internal.h.
1595 * Fixed silc_server_packet_broadcast to send correct broadcast
1598 * The channel key is now distributed to the local client as soon
1599 as it is received from the router (in router environment) so that
1600 no other packet may be sent for the channel until client has
1603 * silc_server_remove_channel_user now broadcasts the received
1604 Remove Channel User packet if it is not broadcast packet already.
1605 The router must broadcast to inform other routers about removed
1608 * Added users field into SilcPacketContext that is a reference count
1609 of the context. One can increase the reference count by calling
1610 silc_packet_context_dup which is now changed to just increase the
1611 reference count instead of duplicating the data. The reference
1612 count is decresed by calling silc_packet_context_free that will
1613 free the data after the reference count hits zero.
1615 For now on the packet context and everything allocated into it
1616 (including the raw packet from network) must be freed by calling
1617 the new silc_packet_context_free function. Added also new function
1618 silc_packet_context_alloc that must be used now to allocate the
1619 context. This also means that if a routine is asynchronous from
1620 silc_[client/server]_packet_parse_type the packet context must
1621 be duplicated by calling silc_packet_context_dup. Otherwise it
1622 gets free'd after silc_[client/server]_packet_parse_type returns.
1623 Also, one must remember that if packet is duplicated then its
1624 reference count must be decresed by calling the free function as
1625 many times as it was duplicated.
1627 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1628 from both client and server.
1630 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Made joining to a channel working in router environment.
1634 * Cleaned up JOIN command on server side and create function
1635 silc_server_command_join_channel internal routine to make the
1638 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Changed silc_command_pending list to SilcDList. Also, added
1641 `ident' field to SilcServerCommandPending structure to identify
1642 the reply and to call correct callback.
1644 Added silc_server_command_pending_check function to replace the
1645 corresnponding macro. The silc_command_pending list is not
1648 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1649 to set identifier to previously allocated Command Payload. It
1650 is used to set identifier for command when resending Command
1653 * Added silc_command_payload_encode_payload to encode Command
1654 Payload buffer from SilcCommandPayload structure.
1656 * Added silc_argument_payload_encode_payload to encode Argument
1657 payload buffer from SilcArgumentPayload structure.
1659 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Changed WHOIS command to support router connection on server side.
1662 The whois request is always sent to router unless the server is
1663 standalone server. After server has received the reply from the
1664 router will it send the reply to the client.
1666 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1667 broadcast received broadcast packet. The function is used only
1668 by router. The broadcast packet is always sent to the router's
1671 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1672 render given ID to printable string, for log files for example.
1674 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Made basic router to router connections working. At least they
1677 can now connect to each other but nothing really works the way
1678 they are supposed - yet.
1680 * Added new initiator token to RouterConnection configuration
1681 file in silcd/serverconfig.[ch]. It is used to tell whether we
1682 are the initiator to the remote router or whether we'll expect
1683 the other end to connect.
1685 * Moved registering of listener task to silc_server_init, hence
1686 the server starts listenning as soon as it is run, even if it
1687 does not have connections to other routers. Let's see how well
1690 * Changed default connection retry timeouts for more suitable in
1693 * Removed cipher and such arguments from silc_idlist_add_client
1694 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1695 Added new function silc_idlist_add_data to add the keys and stuff
1698 * Added SilcIDListData structure and added it to SilcClientEntry
1699 and SilcServerEntry as their first field in the structure. This
1700 way we can explicitly cast the ID entries to the SilcIDListData
1701 structure and get common data for the entries. In past, we had
1702 to first check what type of connection it is and then cast it to
1703 correct ID entry type. Now, we can directly cast the opaque
1704 pointer to the SilcIDListData (no matter what ID entry it actually
1705 is) and get the data needed.
1707 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1710 in some circumstances even if threre were timeout tasks, though not
1711 IO tasks, but tasks anyway. Now fixed.
1713 * Defined SilcServerConnection structure to hold connection specific
1714 stuff about directly connected servers and routers. The definition
1715 is currently in silcd/server_internal.h. I thought about having
1716 a bit more important role fro this struct but for now it is used
1717 only when connecting to other server (or router actually).
1719 * Added connecting retry support in server when connecting to
1720 router(s). The retry feature implement exponential backoff
1721 algorithm. Also, added SilcServerParams structure to hold default
1722 parameters for server. For now, it include these retry settings
1723 and are hard coded. After server is moded to be as Silc Server
1724 Library this structure will be more important.
1726 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Changed client librarys channel->clients table to SilcList and
1729 changed code accordingly.
1731 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Changed client's channel table to SilcList and changed code
1734 accordingly. Also changed SilcChannelClientEntry to include back-
1735 pointer to the channel so that client entry can use that structure
1736 as list as well and we have fast cross-reference to the channel.
1737 This change dramatically decreased the complexity of channel
1738 handling with client entry and vice versa (removed one extra
1739 loop when searching for channel entry from many functions).
1741 * Changed server->sim from table to SilcDList and changed code
1744 * NAMES command can now be used from user interface. It will show
1745 the user list on the channel, neatly.
1747 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1748 Code now saves realname of the user if it becomes available.
1750 * Renamed configure.in to configure.in.pre and made ./prepare
1751 script to automatically add correct version string to
1752 configure.in which it creates from configure.in.pre.
1754 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1756 * NAMES command reply now shows users mode with the nickname when
1759 * Moved silc_client_ch[u]mode[_char] functions from
1760 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1761 place sucks, they are utility functions and should be in some
1764 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1766 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1769 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Added TRQ (efficient deque and list library) into lib/trq. This is
1774 a very good list library that is currently used in the SILC. Defined
1775 SilcList API over the library because I didn't like the API very
1776 much. See lib/trq/silclist.h for the API and examples of how to
1777 use the API. Fixed various places in the code to use the new
1778 SilcList API. The SilcList is meant for lists that has a structure
1779 already defined as a list. It is not suitable to add just some
1780 context to the list (in TRQ, the context is the list actually).
1782 So, I defined SilcDList that can be used for the purpose where
1783 predefined list structure does not exit. This can be used as
1784 such list. Now some context just can be added to the SilcDList.
1785 Currently this list is not used in the SILC just yet, though there
1786 are a lot places where this can replace dynamically allocated
1787 tables and I will fix these places, later, to use SilcDList.
1788 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1789 and use TRQ internally).
1791 Also fixed some annoying warning messages that the original TRQ
1792 code generated. Also minor changes to TRQ's Makefile.in.
1794 * Added support for querying by Client ID to both WHOIS and
1795 IDENTIFY commands into server, as required by the protocol.
1797 * Removed method function pointers from SilcBuffer structure. They
1798 weren't used to anything and just increased the context size for
1799 no good reason. This change also made silc_buffer_alloc and
1800 silc_buffer_free functions inline functions.
1802 * Disabled command flooding detection support until it's fixed so
1803 that it accepts commands in but does not execute them more than once
1806 * Added silc_net_localhost(), to return local hostname, into
1807 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1808 that must be initialized before calling silc_client_init.
1810 * Added new function: silc_server_send_notify_on_channels to send
1811 notify messages to all channels client has joined. It is assured
1812 that the message is sent only once per client.
1814 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1815 lib/silcutil/silcutil.[ch] as silc_format function. The new
1816 function is generic and is used by server as well, not only by
1817 the logging routines.
1819 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1820 the provided version string was not acceptable. Added new function:
1821 silc_ske_check_version into lib/silcske/silcske.h. The function
1822 must be implemented by the application (client or server) and it
1823 does not reside in the SKE library. The function checks the version
1824 string remote end sent.
1826 * Added back pointers (to opaque context and to SilcSocketConnection)
1827 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1829 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1830 duplicate packet context structure.
1832 * Changed `notify' client operation to send same arguments as client
1833 receives from server except for ID's. ID's are mapped to correct
1834 ID entry and that is returned. Also, if channel entry is not sent
1835 by server but the notify is for channel the channel entry is sent
1836 to application (otherwise application doesn't know that it is for
1837 channel (library gets it from packet's Destination ID)).
1839 * Added silc_client_remove_from_channels into client library to
1840 remove a client from all channels it has joined to. Used when
1841 received SIGNOFF notify from server. Added also new function
1842 silc_client_replace_from_channels to replace old ID entry with
1843 new ID entry on all channels. Used when received NICK_CHANGE
1846 * Fixed ID Cache list handling in silc_idlist_get_client in
1847 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1848 to get (or query) client by ID.
1850 * Updated TODO list.
1852 * Added connection authentication status message defined by the
1853 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1854 support for these into the code in client and server side.
1856 * Added generic function silc_client_send_command to send any command
1857 with variable argument list. Application should use this function
1858 to send commands if the command functions provided by the library
1859 does not suite for the application's user interface needs.
1861 * Added new `failure' client operation. Application is notified about
1862 received failure packet if client is executing a protocol. In this
1863 case the protocol's execution has failed.
1865 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1866 is required by the protocol.
1868 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1869 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1872 * Added status flag to SilcSKE object to indicate realtime status
1873 of the SKE protocol.
1875 * Application receives now exactly same command reply arguments as
1876 the library receives from server. However, if ID is received the
1877 corresponding ID entry is returned to the application (eg. Client
1878 ID is mapped to correct SilcClientEntry entry and that is returned).
1879 Changed command_reply client operation due to this change.
1881 * Changed all ID's in commands and in command replys as ID Payloads.
1882 Change affected both client and server side codes.
1884 All ID's sent in SILC network (with execption of ID's in SILC
1885 Packet header) are sent in ID Payload to support variable length
1888 * Server now notifies nick changes and notifies all clients on
1889 the channels about the new nickname (about the new Client ID,
1892 * Implemented CMODE command to change channel modes. Supports all
1893 channel modes defined by the protocol specs except ban and invite
1894 lists. (Also, private channel key mode is supported but support for
1895 setting private channel key in client is missing, thus, this mode
1896 has no effect on client side (except that server requires that the
1897 client uses private channel key and normal channel traffic does not
1900 Also, invite mode works per se, but INVITE command does not work
1901 yet correctly, so you can set channel as invite only channel but
1902 inviting clients to the channel does not work (it is yet to be
1903 thought what's the best way to do it).
1905 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1906 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1907 Implemented CUMODE command to change user's mode on the channel.
1908 Supports all modes defined by the protocol specs.
1910 * Added NAMES command reply to return users modes on the channel.
1912 * Removed unnecessary and slow ciphers from lib/silccrypt.
1914 * Set SO_KEEPALIVE option to connection sockets by default.
1916 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1918 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1919 redefined the Notify Payload into protocol specs.
1921 * Added silc_id_payload_parse_id to get ID directly from raw
1924 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1927 accept searching by Client ID as well.
1929 * Added support for LEAVE and SIGNOFF notify types in client library.
1931 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1932 to parse ID Payload from raw data.
1934 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added flags parameter into silc_ske_assemble_security_properties
1937 function in lib/silcske/silcske.[ch].
1939 * Changed notify client operation to fit better for notify messages
1940 sent by server. The notify payload received from server is now
1941 passed to the application (after parsing it to SilcNotifyPayload).
1942 It is application's responsibility to retrieve the arguments
1943 from the payload and show the message the way it wants. The message
1944 sent by server is implementation specific.
1946 * Changed public keys to comply with the protocol specification.
1947 Old public keys are not supported anymore and are not compatible.
1949 * Removed nickname from Channel Payload as the latest draft removed
1950 it. The client must resolve the nickname from the NAMES command
1951 reply received when it joined the channel.
1953 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1955 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Fixed some errors in protocol specification drafts.
1959 * Created lib/silccore/silcnotify.c to implement Notify Payload
1960 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1961 generic payloads described by protocol specifications. The file
1962 includes implementations for ID Payload and Argument Payload.
1964 * Changed Command Payload implementation to use the new Argument
1965 Payload. Changed command_xxxx_payload to command_payload_xxxx
1966 to comply with SILC coding conventions.
1968 * Added suppport for Argument Payload handling in Notify Payload
1969 implementation as protocol requires it. Added the new support
1970 into server and client lib as well.
1972 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1974 * Added support for multiple nicknames on same channel. [n] is
1975 added locally to the nickname if there are more than one same
1976 nicknames on the channel.
1978 * Server now sends all nicknames that matched WHOIS request.
1979 Client also shows the list received from server.
1981 * Added TOPIC command to client side. User can now set and show
1982 current topic on channel.
1984 * Added MOTD command to client and server. Also, server sends the
1985 motd when client connects to the server.
1987 * Changed version strings to comply ISO 8601.
1989 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Fixed protocol error handling in client library. It should now
1992 cope even if the SKE fails for some reason.
1994 * Made new protocol specification drafts for submitting to IETF.
1996 * Implemented TOPIC command to server in silcd/command.c.
1998 * Added two new notify types into lib/silccore/silcnotify.h:
1999 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2000 notify nickname change and topic setting/change on a channel.
2002 * API change of command_reply operation in client library. The
2003 application gets now the status type received from server as well.
2005 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2009 * Cras fixed and optimized the packet handling even further and
2010 it should work now. Minor change to the prototype of function
2011 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2013 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added new function into lib/silcutil/silcschedule.[ch]:
2016 silc_schedule_with_fd to select() a specified fd. The function
2017 returns after timeout expires or data arrives or goes. The
2018 function is used by packet routines to wait that all data is
2019 received from network.
2021 * Fixed data reading from network in lib/silccore/silcpacket.c.
2022 The code now assures that all data is read from the fd and then
2023 continues packet processing. This was a bug fix since the code
2024 used to drop some data in some circumstances.
2026 * Added new function into lib/silcclient/client.[ch]:
2027 silc_client_start_key_exchange to start key exchange after
2028 connection has been established to server. The code internally
2029 now uses this funtion but its main purpose was to provide it
2030 for applications that perform their own connecting. After
2031 application has created a connection it merely calls this
2032 function to start the key exchange between client and server.
2033 The library takes care of everything else after that.
2035 Updated also lib/silcclient/README to explain the usage of
2038 * Do not send to application information that connection has
2039 been established. Application gets notified it by connect
2042 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Applied cras's patch to add silc_schedule_one function. The
2045 function runs scheduler once and returns.
2047 * Fixed the scheduler after cras messed it up. The timeout
2048 handling works now as it's supposed to work.
2050 * Added into lib/silccore/ silcnotify.h to include notify
2051 message types support. Changed silc_server_send_notify*
2052 functions, in server.[ch], to support those new notify types.
2053 Added the support for the notify types into client library,
2054 as well. Added new notify client operation into ops.h in
2057 * Changed silc_server_packet_send_to_channel to send normal
2058 packets instead of just channel message packets. The function
2059 is now used to send the notify packets to channels. It is not
2060 used to send channel message packets anymore, as server never
2063 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2064 va_arg()s as it seems to require it nowadays. I guess, if SILC
2065 is compiled with older va_arg() the new code should work anyway.
2067 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Splitted core library. Core library (lib/silccore) includes
2070 now only SILC protocol specific core (and common) components.
2071 Created new utility library (lib/silcutil) that includes more
2072 generic purpose stuff. The stuff for util library was taken
2073 from the old core library. This was minor and easy split.
2075 * Created SILC Client Library (lib/silcclient) that includes
2076 implementation of the SILC client without user interface. This
2077 was major move from silc/ directory. The code has been changed
2078 so that it is transparent towards the user interface. The
2079 silc/ directory includes now the same user interface as before
2080 and it uses the new client library. Read lib/silcclient/README.
2081 Basicly, the client library performs everything else related
2082 to SILC except user interface handling. Also, configuration
2083 files are considered to be part of user interface and library
2084 does not handle them.
2086 This change also changed a lot of structures, function naming etc.
2087 Most important change was that SilcClientWindow object was
2088 renamed to SilcClientConnection in the client library. Created
2089 also new file lib/silcclient/ops.h. Also added new files
2090 silc/local_command.[ch] and silc/client_ops.[ch].
2092 All these changes were made to make it easier for user interface
2093 designers to create what ever user interface for the SILC client
2096 It is also expected that the server will be moved to lib
2097 directory as well and SILC Server Library will be created;
2098 sometimes in the future.
2100 * Removed Local commands from lib/silccore/silccommand.h as
2101 they are application specific and new client library does not
2102 handle any of those anymore.
2104 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2105 old client implementation in silc/.
2107 * Added support for callback functions in SILC_LOG_* macros.
2108 Application can now set its own callbacks that will be called
2109 instead of using the default functions that will always print
2110 the debug messages to stderr (or stdout). Also, debugging can
2111 now be disabled by setting silc_debug to FALSE and re-enabled by
2112 setting it to TRUE. Note, that logging will still work even
2113 if debugging is disabled.
2115 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2116 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2117 silc_log_reset_debug_callbacks.
2119 * To enable debugging in silc client one must give now -d
2120 option on command line.
2122 * Changed silc_schedule_init to automatically allocate task queues
2123 if they are not allocated before calling it.
2125 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Added GMP 3.1 into math library.
2129 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2132 a channel in SILC network. The packet is used by servers and
2133 routers to notify other routers that user has left a channel.
2134 This little feature was missing until now. Added the feature
2135 to protocol specification as well.
2137 Added functions: silc_server_send_remove_channel_user and
2138 silc_server_remove_channel_user into server.[ch].
2140 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2141 lib/silccore/silcpacket.h. However, they are not implemented
2144 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Fixed joining to a channel and sending channel messages
2147 between server and router. The channel message sending should
2148 now work inside a cell.
2150 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Fixed the private message sending between server and router.
2153 The private message sending should now work inside a cell.
2155 * Added silc_server_replace_id into server.[ch] to replace
2156 existing ID in the SILC network.
2158 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2159 and silc_idlist_replace_server_id into idlist.[ch] in server.
2161 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Fixed the server to server connections. Server can again now
2164 connect to router. Router to router connections probably does
2167 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Added dynamic protocol registering support. Now protocols can
2170 registered and unregistered on the fly. Patch by cras.
2172 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Added lib/contrib directory to hold routines that some platforms
2175 don't have but are needed by SILC.
2177 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2178 into lin/contrib to provide getopt() and getopt_long() for
2179 those who don't have it.
2181 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Added AWAY command to client. When away message is set and
2184 client receives a private message packet the client automatically
2185 replies to the sender with the away message.
2187 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2188 bug seemed to be the cause of recent problems when compiling
2191 * Added version detection support to SKE protocol specification
2192 and added the new changes to the SKE implementation as well.
2193 There were other minor changes in the SKE protocol as well.
2195 Many changes in lib/silcske/silcske.[ch] and in
2196 lib/silcske/payload.[ch].
2198 * Added ^U functionality, clear input line. Patch from cras.
2200 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Mainly small bugfixes on core library. Fixed some debugging
2203 logging and buffer overflow in silclog.c.
2205 * Updated config.sub and config.guess on the distribution tree.
2207 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Added command lagging support in server. Client may execute
2210 commands now only once in two seconds.
2212 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Optimized packet reception. MAC computation and checking is now
2215 also more optimized. A lot previously duplicated code is now
2216 used as generic by both client and server.
2218 * Fixed key pair generation in clientutil.c
2220 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Added into lib/silccore/silcbufutil.[ch] new function;
2223 silc_buffer_realloc.
2225 * Moved generic packet sending/encryption functions to
2226 lib/silccore/silcpacket.[ch] from client and server. Some
2227 rewriting of the functions.
2229 * Moved all generic packet reception/decryption functions to
2230 lib/silccore/silcpacket.[ch] from client and server. The
2231 packet processing is now much cleaner in both client and server.
2232 These were major changes in both client and server.
2234 * Created many common functions in server to do packet sending.
2235 Previously code were duplicated a lot, this has been removed
2238 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Rewrote major parts of the ID cache system. Don't know
2241 whether it is better now or not but at least the API is more
2244 * Major rewrite on ID cache stuff on client because of the ID
2245 cache API changes. Added idlist.c to client.
2247 * Also major rewrite on ID cache stuff on server as well.
2248 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2249 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2250 in hand, instead they are all put into the ID cache system now.
2251 All server_idlist_* routines uses ID cache now instead of
2252 traversing its own lists (those lists does not exist anymore).
2253 SilcIDList though still exists. Also, SilcXXXEntry's are
2256 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Finally made the SKE implementation compliant to the protocol
2259 specification. All mp integers are now binary encoded as
2260 opposed being HEX encoded.
2262 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2265 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2266 functions: silc_[encode/decode]_pem. Also added function
2267 silc_encode_pem_file to PEM encode with newlines ('\n') for
2270 * SILC public keys are now encoded either PEM or binary. Same
2271 option is for private keys as well. By default private keys
2272 are binary encoded and public keys PEM encoded. Silly HEX
2273 encoding were removed.
2275 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2276 function to create fingerprints.
2278 * Fixed a bug in SHA1; does not change the original data anymore.
2280 * Partly implemented INFO command on client and server side.
2281 Fixed CLEAR command. Changes to SERVER command; show current
2282 server(s) when giving command without arguments. Added
2283 VERSION command to client.
2285 * Added check to server that unregistered connections cannot
2286 execute commands (unless it is specificly allowed).
2288 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Fixed screen refresh.
2292 * Fixed channel joining bug from client. On some circumstances
2293 client tried to join to a channel it had already joined.
2295 * Added public key verification process into client's protocol.c.
2296 The client now verifies the public key from user and saves
2297 it into ~./silc/serverkeys/ directory.
2299 Added into: clientutil.[ch]: silc_client_verify_server_key.
2301 * Changed SKE protocol's silc_ske_initiator_finish function
2302 to accept callback function that verifies the received public
2303 key. Removed old silc_ske_verify_public_key function.
2305 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2308 silc_pkcs_private_key[_data]_set.
2310 * Made the password and public authentication more cleaner in
2311 server's protocol.c.
2313 * Removed historic and obsolete protocol `channel_auth' from
2314 both client and server.
2316 * Removed wrong way of sending command status messages from
2317 server to client in server's command.c. The old way violated
2318 protocol specification.
2320 Changes to silccore/silccommand.[ch]: removed
2321 silc_command_encode_status_payload -> not needed anymore,
2322 changed silc_command_encode_payload_va to accept extra
2323 argument on variable argument list. The argument type must
2324 now be provided to the function. Also, added new function:
2325 silc_command_encode_reply_payload_va which is same as
2326 normal command_encode_payload_va except command status type
2327 is provided as extra argument.
2329 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Added ~./silc directory handling. The directory includes the
2332 public and private keys for the client.
2334 Added silc_client_check_silc_dir, silc_client_create_identifier
2335 and silc_client_load_keys.
2337 * Implemented SILC protocol compliant public key. Added public
2338 and private key saving to and loading from files.
2340 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2341 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2342 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2343 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2344 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2346 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2347 silc_pkcs_load_[public/private]_key.
2349 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Added silc_server_get_route (route.[ch]) to get connection
2352 data for the fastest route for given ID.
2354 * Implemented INVITE command on client and server. The command
2355 were re-defined in the SILC Protocol Specification and the
2356 implementation now complies with the specification.
2358 * Implemented PING command on client and server.
2360 * Implemented NAMES command on client and server. The server side
2361 supports currently only normal server not router server yet.
2362 Some changes to NAMES definition in SILC protocol specification.
2364 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Implemented LEAVE command on client and server.
2368 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2369 again. This change was made to the protocol as well. Server
2370 should not violate the protocol specification anymore.
2372 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2375 was tested. SOCKS4 was not but should work anyway.
