1 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Changed the format of AdminConnection configuration section
4 in the server. Added username of the admin to the format.
5 Affected files silcd/serverconfig.[ch].
7 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
8 to return admin configuration data by host, username and/or
11 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Implemented WHOWAS command to the server. Added the functions:
15 silc_server_command_whowas_parse,
16 silc_server_command_whowas_send_reply,
17 silc_server_command_whowas_from_client and
18 silc_server_command_whowas_from_server
20 * Added <Client ID> argument to the WHOWAS command reply. Updated
21 the protocol specs accordingly.
23 * Implemented WHOWAS command and command_reply to the client
26 Implemented the WHOWAS printing on the user interface.
28 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * Added new argument to the WHOWAS command reply, the real name.
31 It is an optional argument. Updated the protocol specs.
33 * Added SilcIDCacheDestructor callback that is registered when
34 the SilcIDCache is allocated. The callback is called when
35 an cache entry in the ID Cache expires, or is purged from the
36 cache. Added into lib/silccore/idcache.[ch].
38 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
39 to destruct the client entries when the cache entry expires.
40 Other ID Cache's in server and in the client library ignores
43 * If the ID Cache entry's `expire' field is zero then the entry
44 never expires. Added boolean `expire' argument to the
45 silc_idcache_add function in the lib/silccore/idcache.[ch].
46 If it is TRUE the default expiry value is used.
48 * Added silc_server_free_client_data_timeout that is registered
49 when client disconnects. By default for 5 minutes we preserve
50 the client entry for history - for WHOWAS command.
52 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Added support to the server to enforce that commands are not
55 executed more than once in 2 seconds. If server receives
56 commands from client more frequently, timeout is registered
57 to process the commands. Affected file silcd/command.c.
58 Added new function silc_server_command_process_timeout.
60 * Changed NICK_NOTIFY handling in client library to check that
61 if the client's nickname was changed, so there is no need to
62 resolve anything from the server.
64 * Removed error printing from the WHOIS and IDENTIFY commands.
65 If error occurs then it is ignored silently in the client library.
66 The application, however, may map the received error to
67 human readable error string. The application currently maps
68 the NO_SUCH_NICKNAME error to string.
70 * Made the command status message public to the application. Moved
71 them from lib/silcclient/command_reply.c to
72 lib/silcclient/command_reply.h. The application can map the
73 received command status to the string with the
74 silc_client_command_status_message function.
76 * Added check to the server to check that client's ID is same
77 as the Source ID in the packet the client sent. They must
80 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
82 * Added dist-bzip hook to the Makefile.am to make bzip2
83 compressed distributions.
85 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Server now enforces the maximum length for the nickname and
88 the channel as protocol specification dictates. 128 bytes for
89 nickname and 256 bytes for channel name.
91 * Moved the WHOIS printing to the application. The client libary
92 does not print out the WHOIS information anymore, the application
93 must do it. Renamed silc_client_command_reply_whois_print to
94 the silc_client_command_reply_whois_save.
96 The client's idle time is also sent to the application now, and
97 the idle is shown on screen.
99 * Added silc_client_command_reply_identify_save to save the
100 received IDENTIFY entries.
102 * Do not check for channel private keys in message sending and
103 reception if the channel does not have the PRIVKEY mode set.
104 Affected file lib/silclient/client_channel.c.
106 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
109 just surfaced after chaning the JOIN procedure.
111 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Added silc_client_get_clients_by_list to get client entries
114 from Client ID list, that is returned for example by JOIN
115 and USERS command replies. The application should use this
116 function for example when JOIN command reply is received to
117 resolve the clients already on the channel (library does not
118 do that anymore as USERS command reply is not used in the JOIN
119 procedure anymore). Affected files lib/silcclient/silcapi.h and
120 lib/silcclient/idlist.c.
122 * JOIN command reply and USERS command reply returns now SilcBuffer
123 pointers instead of unsigned char pointers when returning
124 the client list and mode list.
126 * Added <Client ID> argument to the JOIN command reply, mainly
127 for the server to identify for which client the command was
128 originally sent. Updated protocol specs accordingly.
130 * Added SilcDlist private_key pointer to the SilcChannelEntry
131 in the client to support the channel private keys. Affected
132 file is lib/silcclient/idlist.h.
134 * Added SilcChannelPrivateKey argument to the function
135 silc_client_send_channel_message so that application can choose
136 to use specific private ke if it wants to. If it is not provided,
137 the normal channel key is used, unless private keys are set.
138 In this case the first (key that was added first) is used
139 as the encryption key.
141 * Implemented the support for channel private key handling.
142 Implemented the following functions:
144 silc_client_add_channel_private_key,
145 silc_client_del_channel_private_keys,
146 silc_client_del_channel_private_key,
147 silc_client_list_channel_private_keys and
148 silc_client_free_channel_private_keys
150 Affected file lib/silcclient/client_channel.c.
152 * Added the support for the private keys in the channel message
153 sending and encryption and in the message reception and
154 decryption. Affected funtions are
155 silc_client_send_channel_message and silc_client_channel_message.
157 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Added SKE's key verify callback to the client library's
160 KE protocol context. Affected files lib/silcclient/protocol.[ch].
162 * Removed the statement that server (or router) must send USERS
163 command reply when joining to the channel so that the client
164 knows who are on the channel. Instead, the client list and
165 client's mode list is now sent in the JOIN command reply to the
166 client who joined channel. This is better solution.
168 * Added function silc_server_get_users_on_channel and function
169 silc_server_save_users_on_channel to the silcd/server.[ch].
171 * Removed function silc_server_command_send_users from the
174 * Do not show topic on the client library anymore. The topic is
175 sent in the command reply notify to the application and the
176 application must show the topic now.
178 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Added client searching by nickname hash into the IDENTIFY and
181 WHOIS commands in the server as they were clearly missing from
182 them. Affected file is silcd/command.c.
184 * Fixed a bug in private message receiving in the client library.
185 The remote ID was freed and it wasn't supposed, now it is
188 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Minor fix to the channel payload; allocate the data area, as it
191 needs to be of specific length.
193 * If the key agreement port is zero then the operating
194 system will define the bound port. Affected files are
195 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
197 * Added new function silc_channel_payload_decrypt into the file
198 lib/silccore/silcchannel.[ch].
200 * Moved the channel message etc, check from silc_packet_decrypt
201 to applications. The library calls now a generic
202 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
203 when the packet is either normal or special. This was done to
204 allow more wide range of checking that was not allowed when
205 the code was in library. Now applications can do virtually any
206 checks to the packet and return to the library the decision how
207 the packet should be processed. Affected files are
208 lib/silccore/silcpacket.[ch].
210 Added silc_server_packet_decrypt_check to the server and
211 silc_client_packet_decrypt_check to the client library.
213 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
214 to send with specified source and destination information.
216 * Channel message delivery between routers was broken after the
217 channel key distribution was fixed earlier. The channel key
218 was used be to distributed to other routers as well which is not
219 allowed by the protocol. Now this is fixed and channel keys
220 really are cell specific and the channel message delivery between
221 routers comply with the protocol specification.
223 * Fixed various commands in server to check also the global list
224 for the channel entry and not just the local list. The affected
225 file silcd/command.c.
227 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Added assert()s to buffer formatting and unformatting routines
230 to assert (if --enable-debug) when error occurs. Affected
231 file: lib/silcutil/silcbuffmt.c.
233 * Changed to auto-reconnect to check whether the remote host is
234 router and register the re-connect timeout if it is. It used
235 to check that whether we are normal server, but router must do
236 auto-reconnect with another router as well. Affected file
239 * Removed the [<key len>] option from CMODE command as the cipher
240 name decides the key length, nowadays. See the defined ciphers
241 from the protocol specification.
243 * Added [<hmac>] option to the CMODE command to define the HMAC
244 for the channel. Added SILC_CMODE_HMAC channel mode.
246 * Added [<hmac>] option for the JOIN command so that user can
247 select which HMAC is used to compute the MACs of the channel
250 * Added Hmac field to the Channel Message Payload. The integrity
251 of plaintext channel messages are now protected by computing
252 MAC of the message and attaching the MAC to the payload. The
253 MAC is encrypted. Now, it is clear that this causes some
254 overhead to the size of the packet but rationale for this is that
255 now the receiver can verify whether the channel message decrypted
256 correctly and also when private keys are set for the channel the
257 receiver can decrypt the packet with several keys and check from
258 the MAC which key decrypted the message correctly.
260 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
261 lib/silccrypt/silccipher.[ch].
263 * Added silc_hash_len to return the digest length into the
264 lib/silcrypt/silchash.[ch].
266 * Rewrote parts of Silc Channel Payload interface in the
267 lib/silccore/silcchannel.[ch]. The encode function now also
268 encrypts the packet and parse function decrypts it.
270 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Fixed a minor formatting bug in the SKE's key material processing.
273 It actually might have processed the keys wrong way resulting
276 * Redefined the mandatory HMAC algorithms and added new algorithms.
277 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
278 and hmac-md5 truncated to 96 bits. The mandatory is now
279 hmac-sha1-96. Rest are optional (including the one that used
280 to be mandatory). Rationale for this is that the truncated HMAC
281 length is sufficient from security point of view and can actually
282 make the attack against the HMAC harder. Also, the truncated
283 HMAC causes less overhead to the packets. See the RFC2104 for
286 * Added new [hmac] configuration section. The SKE used to use
287 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
288 is of course wrong. The official names that must be proposed in
289 the SKE are the ones defined in the protocol specification
290 (hmac-sha1-96 for example). The user can configure any hmac
291 using any hash function configured in the [hash] section. At
292 least, the mandatory must be configured.
294 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
296 * Added HMAC list to the SKE proposal list. It has now both
297 hash algorithm list and HMAC list. This makes the protocol
298 incompatible with previous versions. The SKE now seems to work
299 the way it is supposed to work, for the first time actually.
301 * Defined plain Hash algorithms to the protocol specification.
304 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Implemented support for key agreement packets into the server.
307 Added functions silc_server_key_agreement and
308 silc_server_send_key_agreement. Other than these functions,
309 server has nothing to do with this packet.
311 * Added support for private message key packets into the server.
312 Added functions silc_server_private_message_key and
313 silc_server_send_private_message_key.
317 * Changed the silc_[client|server]_protocol_ke_set_keys to be
318 called in the protocol's final callback instead in the END
319 protocol state. This makes a little more sense and in the same
320 time in client we can use the same protocol routines for normal
321 key exchange and to key agreement packet handling as well.
323 * Added to both client's and server's KE protocol context the
324 SilcSKEKeyMaterial pointer to save the key material. We will
325 bring the key material to the protocol's final callback by doing
326 this. The final callback must free the key material.
328 * Added SKE's packet_send callback into client's KE protocol
329 context so that the caller can choose what packet sending function
330 is used. This way we can use different packet sending when
331 doing normal SKE when doing key agreement packet handling (in
332 the key agreement packet handling we do not want to encrypt
335 * Implemented the responder side of the key agreement routines
336 in the client. The client can now bind to specified port and
337 accept incoming key negotiation. The key material is passed
338 to the application after the protocol is over.
340 * Implemented the processing of incoming Key Agreement packet
341 in the client. Added function silc_client_key_agreement to
344 * Implemented the intiator side of the key agreement routines
345 in the client. The client can now initiate key agreement with
346 another remote client. The key material is passed to the
347 application after the protocol is over.
349 * Created client_keyagr.c to include all the key agreement
352 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
353 SILC_TASK_CALLBACK except that it is not static.
355 * Created client_notify.c and moved the Notify packet handling
356 from the client.[ch] into that file.
358 * Created client_prvmsg.c and moved all private message and
359 private message key routines from the client.[ch] into that file.
361 * Create client_channel.c and moved all channel message and
362 channel private key routines from the client.[ch] into that file.
364 * Changed silc_client_get_client_by_id_resolve to resolve with
365 WHOIS command instead of IDENTIFY command, in the file
366 lib/silclient/idlist.c.
368 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Implemented the SKE's responder side to the Client library.
372 * When FAILURE is received to the protocol do not trust it
373 blindly. Register a timeout to wait whether the remote closes
374 the connection as it should do it, only after that process the
375 actual failure. This was changed to both client and server.
377 * Added client_internal.h to include some of the structures
378 there instead of client.h in lib/silcclient/.
380 * Added function silc_task_unregister_by_callback to unregister
381 timeouts by the callback function.
383 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Some "Incomplete WHOIS info" errors has been appearing on the
386 log files. Took away the entry->userinfo check from WHOIS
387 reply sending. The entry->userinfo is now " " if client did not
388 provide one. I thought this was fixed earlier but something
389 is wrong still. Let's see if the error still appears.
391 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Fixed a minor bug in the login when the channel key is
394 re-generated in the server. It used to generate the key in
395 wrong order and thus caused problems in the channel traffic.
397 * Fixed a minor bug in channel key distsribution after
398 KICK command. The key was not sent to the router even though
401 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Added silc_ske_process_key_material_data as generic routine
404 to process any key material as the SILC protocol dictates. The
405 function is used by the actual SKE library but can be used by
406 applications as well. This relates to the private message keys
407 and the channel private keys since they must be processed the
408 same way the normal SILC session keys. The protocol dictates
409 this. Affected files: lib/silcske/silcske.[ch].
411 Added also silc_ske_free_key_material to free the
412 SilcSKEKeyMaterial structure.
414 * Defined silc_cipher_set_key function to set the key for
415 cipher without using the object's method function. The affected
416 files: lib/silccrypt/silccipher.[ch].
418 * Implemented silc silc_client_add_private_message_key,
419 silc_client_add_private_message_key_ske,
420 silc_client_del_private_message_key,
421 silc_client_list_private_message_keys and
422 silc_client_free_private_message_keys functions in the
425 Added functions silc_client_send_private_message_key to send
426 the Private Message Key payload and silc_client_private_message_key
427 to handle incoming Private Message Key payload.
429 * Added Cipher field to the Private Message Key payload to set
430 the cipher to be used. If ignored, the default cipher defined
431 in the SILC protocol (aes-256-cbc) is used.
433 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Removed lib/silcclient/ops.h file.
437 Redefined parts of the SILC Client Library API. Created new
438 file silcapi.h that deprecates the ops.h file and defines the
439 published Client Library API. Defined also private message key
440 API and channel private key API into the file.
442 This is the file that the application must include from the
443 SILC Client Library. Other files need not be included by
444 the application anymore.
446 * Added new key_agreement client operation callback and also
447 defined the Key Agreement library API for the application.
449 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
452 is used by clients to request key negotiation between another
453 client in the SILC network. If the negotiation is started it
454 is performed using the SKE protocol. The result of the
455 negotiation, the secret key material, can be used for example
456 as private message key.
458 Implemented the Key Agreement payload into the files
459 lib/silccore/silauth.[ch].
461 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Redefined ciphers for the SILC protocol. Added some new ciphers
464 and defined the key lengths for the algorithms. Changed the
465 code accordingly. The default key length is now 256 bits.
467 * Fixed SKE key distribution function silc_ske_process_key_material
468 when the key length is more than 128 bits. The default key
469 length in SILC is now 256 bits.
471 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
472 to indicate unsupported algorithm.
474 * Renamed rijndael.c to aes.c and all functions as well.
476 * Fixed a long standing channel key setting bug in client library.
477 Weird that it has never surfaced before.
479 * Fixed bug in channel deletion. If the entire channel is removed
480 then it must also delete the references of the channel entry
481 from the client's channel list as the client's channel entry and
482 the channel's client entry share same memory.
484 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Implemented CONNECT and SHUTDOWN commands in the client.
488 * Implemented CLOSE command to the client.
490 * Added the function silc_idlist_find_server_by_name into the
491 files silcd/idlist.[ch].
493 Added the function silc_idlist_find_server_by_conn into the
494 files silcd/idlist.[ch].
496 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * DIE command was renamed to SHUTDOWN. Updated the both code
501 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
502 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
504 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
507 * Added function silc_server_create_connection function to create
508 connection to remote router. My server implementation actually
509 does not allow router to connect to normal server (it expects
510 that normal server always initiates the connection to the router)
511 so the CONNECT command is only good for connecting to another
514 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
517 or some other client was kicked from the channel.
519 Implemented the handling of the notify type to both client
522 Implemented silc_server_send_notify_kicked to send the KICKED
523 notify. It is used to send it to the server's primary router.
525 * Implemented the KICK command into server and client.
527 * Added `query' argument to the silc_idlist_get_client function
528 to indicate whether to query the client from server or not if
531 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
532 to indicate that the client is not channel founder.
536 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Removed the rng context from SilcPacketContext structure and
539 changed that the packet routine uses the Global RNG API.
541 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Added support for quit message that client can "leave" on the
544 channel when it quits the SILC. It is ditributed inside the
545 SILC_NOTIFY_TYPE_SIGNOFF notify type.
547 Added silc_server_free_client_data that will take the
548 signoff message as argument.
550 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
552 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Updated parts of the protocol specification to keep it up
557 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
560 payloads in one packet.
562 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
563 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
564 use now the new List flag.
566 * Also deprecated the following packet types: REPLACE_ID,
567 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
569 * Added list support for Notify packet in server.
571 * Added silc_server_send_notify_channel_change to send the
572 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
573 the silc_server_send_replace_id.
575 * Added silc_server_send_notify_nick_change to send the
576 NICK_CHANGE notify type. Deprecates the function
577 silc_server_send_replace_id.
579 * Added silc_server_send_notify_join to send the JOIN notify type.
580 Deprecates the function silc_server_send_new_channel_user.
582 * Added silc_server_send_notify_leave to send LEAVE notify type.
583 Deprecates the function silc_server_send_remove_channel_user.
585 * Added silc_server_send_notify_cmode and
586 silc_server_send_notify_cumode to send CMODE and CUMODE notify
587 types. Deprecates the silc_server_send_set_mode function.
589 * Added SERVER_SIGNOFF notify type to indicate that server has
590 quit. This means that all clients on the channel from that
591 server will drop. This can be also used when netsplit happens.
593 Deprecated REMOVE_ID packet type since it is not needed anymore
596 Added silc_server_send_notify_server_signoff to send the
597 SERVER_SIGNOFF notify type. Deprecates the function
598 silc_server_send_remove_id.
600 Added also silc_server_send_notify_signoff to send the
603 * Employed the PKCS #1. It is the mandatory way to do RSA in the
604 SILC protocol from this day on. Changed the protocol
605 specification as well.
607 * Added silc_server_send_notify_topic_set to send TOPIC_SET
608 notify type. It is used between routers to notify about
609 topic changes on a channel.
611 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
614 * Partly updated the protocol specification to comply with the
615 changes now made. It is still though a bit outdated.
617 * The JOIN notify type now takes one extra argument <Channel ID>.
618 The packet used to be destined to the channel but now the
619 JOIN type may be sent as list thus it is impossible to
620 destine it to any specific channel. By adding this argument
621 it is again possible.
623 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Added CREDITS file. The CHANGES and CREDITS file will appear
626 in the distribution as well.
628 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
631 types in the server's silcd/packet_receive.c.
633 * Implemented CMODE and CUMODE to work in router environment.
635 * Fixed minor encoding and decoding buglet from the
636 lib/silccore/silcmode.c.
638 * Fixed buffer overflow from lib/silcclient/command.c in USERS
641 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
643 * Changed all SilcConfigServer* and silc_config_server* to
644 SilcServerConfig* and silc_server_config*, respectively.
647 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Associated the ID (client or server ID) to the Authentication
650 Payload to avoid any possibility of forging. Updated the
651 protocol specification and the code accordingly.
653 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * The RSA key length is now save to the RsaKey context in the
656 key generation process in lib/silccrypt/rsa.c. The key length
657 is now used to figure out the maximum size of the block allowed
658 to be encrypted/signed.
660 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
661 is equivalent to the silc_mp_mp2bin but does not allocate any
664 * Changed silc_mp_mp2bin API to take length argument. If it is
665 non-zero then the buffer is allocated that large. If zero, then
666 the size is approximated using silc_mp_sizeinbase, which however
669 * Created Global RNG API which is global RNG that application can
670 initialize. After initializing, any routine anywhere in the
671 code (including library) can use RNG without allocating a new
672 RNG object. This was done to allow this sort of use of the
673 RNG in code that has no chance to allocate RNG object. All
674 applications currently allocate this and many routines in the
675 library use this. Affected file lib/silccrypt/silcrng.[ch].
677 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
678 it to use the Global RNG API.
680 * Defined Authentication Payload into protocol specification that
681 is used during SILC session to authenticate entities. It is
682 used for example by client to authenticate itself to the server
683 to obtain server operator privileges.
685 Implemented this payload into the lib/silccore/silcauth.[ch].
686 Implemented also routines for public key based authentication
687 as the new protocol specification dictates.
689 Moved definitions of different authentication methods from
690 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
692 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
693 silc_pkcs_verify and silc_pkcs_sign_with_hash and
694 silc_pkcs_verify_with_hash functions into the file
695 lib/silccrypt/silcpkcs.[ch].
697 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * The client entry's userinfo pointer must be always valid.
700 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
701 will fail since it requires the userinfo. Now, the userinfo
702 is allocated as "" if actual userinfo does not exist. Actually,
703 it must exist and it is totally Ok to drop client connections
704 that does not announce the userinfo. However, we will make
705 this workaround for now.
707 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
708 to return the remote port by socket.
710 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
713 SILC_SERVER_PENDING_EXEC and added an new macro
714 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
715 data or when error occurs while processing the pending command.
717 Added new argument `destructor' into silc_server_command_pending
718 and to the SilcServerCommandPending object. This destructor is
719 now called after calling the pending callback or if error occurs
720 immediately. If error occurs the actual pending callback won't
721 be called at all - only the destructor. The destructor may be
722 NULL if destructor is not needed.
724 All this applies for client library code as well. Similar
725 changes were made there as well for the pending commands.
727 In the client, the application must now allocate the
728 SilcClientCommandContext with the silc_client_command_alloc
731 * Added reference counter to the SilcServerCommandContext. Added
732 function silc_server_command_alloc and silc_server_command_dup
735 Same type of functions added to the client library for the same
738 * Removed the cmd_ident from IDListData away since it is now
739 global for all connections. It is the command identifier used
740 in command sending and with pending commands. The affected file
743 * Added reference counter to the SilcSocketConnection objecet to
744 indicate the usage count of the object. The object won't be
745 freed untill the reference counter hits zero. Currently only
746 server uses this, and client ignores it. The client must be
747 set to use this too later. The affected files are
748 lib/silccore/silcsockconn.[ch]. Added also the function
749 silc_socket_dup to increase the reference counter.
751 This was mainly added because it is possible that the socket
752 is removed underneath of pending command or other async
753 operation. Now it won't be free'd and proper DISCONNECTING
754 flags, etc. can be set to avoid sending data to connection that
755 is not valid anymore.
757 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
758 the connection. After that it sets SILC_SET_DISCONNECTED.
759 It is, however, possible that the socket data is not still freed.
760 The silc_server_packet_process now checks that data is not
761 read or written to connection that is DISCONNECTED. The socket
762 get's freed when the reference counter hits zero.
764 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Changed the client operation API: channel_message operation's
767 `sender' is now the client entry of the sender, not the nickname
768 and the `channel' is the channel entry, not the channel name.
770 In the private_message operation the `sender' is now also the
771 client entry of the sender not the nickname.
773 Affected file is lib/silcclient/ops.h and all applications
774 using the client operations.
776 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Moved the calling of ops->connect() from connect_to_server_final
779 into receive_new_id functin since that is the point when the
780 client is actually allowed to send traffic to network. The
781 affected file is lib/silcclient/client.c.
783 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
786 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
787 (if needs broadcasting) instead of broadcasting the packets one
788 by one which would make a burst in the network traffic.
790 * Added `broadcast' argument to the functions in silcd/server.[ch]
791 silc_server_create_new_channel[_with_id] to indicate whether
792 to send New Channel packet to primary router.
794 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
796 * Added new function into the silcd/server.[ch] files:
797 silc_server_create_new_channel_with_id to create new channel with
798 already existing Channel ID.
800 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
801 lib/silccore/silcpacket.h. This packet is used t send list of
802 Set Mode payloads inside one packet. Server uses this to set
803 the modes for the channels and clients on those channels, that it
804 announced to the router when it connected to it. The protocol
805 specification has been updated accordingly.
807 * The silc_server_new_channel did not handle the packet coming
808 from normal server as it normally does not send that. However,
809 when it announces its channels it does send it. Implemented
810 the support for that.
812 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
813 into the file lib/silccore/id.h.
815 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Fixed memory leaks in the functions silc_idlist_del_client,
818 silc_idlist_del_channel and silc_idlist_del_server in the file
819 silcd/idlist.c. All of those leaked like a sieve.
821 * Fixed some small memory leaks in the client's function
822 silc_client_notify_by_server.
824 * Added functions into silcd/server.c: silc_server_announce_clients,
825 silc_server_announce_channels and silc_server_announce_server.
826 These functions are used by normal and router server to announce
827 to its primary router about clients, channels and servers (when
828 router) that we own. This is done after we've connected to the
831 These functions effectively implements the following packet types:
832 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
833 and SILC_PACKET_NEW_ID_LIST.
835 * Added new functions into the silcd/packet_receive.[ch]:
836 silc_server_new_id_list, silc_server_new_channel_list and
837 silc_server_new_channel_user_list to handle the incoming
838 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
840 * Added support of changing Channel ID in the function
841 silc_server_replace_id. If the server that announces a channel
842 to the router already exists in the router (with same name but
843 with different Channel ID), router is responsible to send
844 Replace ID packet to the server and force the server to change
845 the Channel ID to the one router has.
847 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
848 client that the Channel ID has been changed by the router. The
849 normal server sends this to the client. Client must start using
850 the new Channel ID as the channel's ID.
852 Implemented handling of this new type into lib/silcclient/client.c
853 into the function silc_client_notify_by_server.
855 * Added new function silc_idlist_replace_channel_id into the files
856 silcd/idlist.[ch] to replace the Channel ID.
858 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Call silc_server_command_identify_check always when processing
861 the IDENTIFY command in silcd/command.c
863 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
866 send keepalive packets. The packet can be sent by clients,
869 Added function silc_socket_set_heartbeat into the file
870 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
871 If not set, the heartbeat is not performed. The actual
872 heartbeat is implemented in the low level socket connection
873 library. However, application is responsible of actually
876 Added silc_server_send_heartbeat to send the actual heartbeat
877 packet into silcd/packet_send.[ch]. Server now performs
878 keepalive with all connections.
880 * Added silc_task_get_first function into lib/silcutil/silctask.c
881 to return the timeout task with shortest timeout. There was a bug
882 in task unregistration that caused problems. TODO has been
883 updated to include that task system must be rewritten.
885 * The client library will now resolve the client information when
886 receiving JOIN notify from server for client that we know but
887 have incomplete information.
889 * Rewrote parts of silc_server_remove_from_channels and
890 silc_server_remove_from_one_channel as they did not remove the
891 channel in some circumstances even though they should've.
893 * Encryption problem encountered in server:
895 The LEAVE command used to send the Channel Key packet to the
896 router immediately after generating it. However, the code
897 had earlier sent Remove Channel user packet but not immediately,
898 ie. it was put to queue. The order of packets in the router
899 was that Channel Key packet was first and Remove Channel User
900 packet was second, even though they were encrypted in the
901 reverse order. For this reason, MAC check failed. Now, this
902 is fixed by not sending the Channel Key packet immediately but
903 putting it to queue. However, this is more fundamental problem:
904 packets that are in queue should actually not be encrypted
905 because packets that are sent immediately gets encrypted
906 actually with wrong IV (and thus MAC check fails). So, packets
907 that are in queue should be encrypted when they are sent to
908 the wire and not when they put to the queue.
910 However, the problem is that the current system has not been
911 designed to work that way. Instead, the packet is encrypted
912 as soon as possible and left to the queue. The queue is then
913 just purged into wire. There won't be any fixes for this
914 any time soon. So, the current semantic for packet sending
917 o If you send packet to remote host and do not force the send
918 (the packet will be in queue) then all subsequent packets to the
919 same remote host must also be put to the queue. Only after the
920 queue has been purged is it safe again to force the packet
923 o If you send all packets immediately then it safe to send
924 any of subsequent packets through the queue, however, after
925 the first packet is put to queue then any subsequent packets
926 must also be put to the queue.
928 Follow these rules and everything works fine.
930 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added new function silc_server_remove_clients_by_server to
933 remove all client entries from ID list when the server connection
934 is lost. In this case it is also important to invalidate all
935 client entires as they hold the invalid server entry. This
936 fixes fatal bug when server has lost connection and will reconnect
939 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Made some sanity checks to silc_server_daemonise like to check
942 whether the requested user and group actually exists.
944 * Added sanity check to SKE's silc_ske_responder_finish to check
945 that the public and private key actually is valid.
947 * Invalidate the client's nickname when receiving Replace ID
948 packet and the Client ID is being replaced. This means that the
949 server will query the nickname if someone needs it (client)
952 * Sort the ID Cache in client library when the ID Cache data
953 has changed (needs sorting).
955 * Do not allow for SILC client to create several connections to
956 several servers. The client does not support windows right now
957 and generating multiple connections causes weird behaviour.
959 Irssi-silc client does support windows and can handle several
960 connections without problems, see: www.irssi.org and SILC plugin.
962 * Fixed some places where client was added to the IDList. The
963 rule of thumb is following (in order to get everything right):
964 If the client is directly connected local client then the
965 `connection' argument must be set and `router' argument must be
966 NULL to silc_idlist_add_client function. If the client is not
967 directly connected client then the `router' argument must
968 bet set and the `connection' argument must be NULL to the
969 silc_idlist_add_client function.
971 * The funtion silc_server_packet_send_local_channel actually did
972 not check whether the client was locally connected or not. It
973 does that now. Fixed a bug related to LEAVE command.
975 * Fixed Remove Channel User payload parsing bug in server's
976 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
978 * The server's silc_server_save_channel_key now checks also the
979 global ID list for the channel as it might not be in the local
980 list. Fixed a bug related to LEAVE command.
982 * Is this the end of the [<unknown>] buglet that has been lurking
983 around for a long time? A little for loop fix in server's
984 silc_server_command_whois_parse that is used by both IDENTIFY
985 and WHOIS command. At least, this was a clear bug and a cause
986 of one type of [<unknown>] buglet.
988 * WHOIS and IDENTIFY commands call the function
989 silc_server_command_[whois/identify]_check function even if
990 we are not router server.
992 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Added --with-gmp configuration option. If set the GMP
995 is always compiled in the SILC source tree. If not set then
996 it is checked whether the system has the GMP3 installed. If
997 it has then the GMP won't be compiled (the system's headers
998 and library is used), if it doesn't have it then the GMP is
999 compiled in the SILC source tree.
1001 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Changed RSA private exponent generation to what PKCS #1
1004 suggests. We try to find the smallest possible d by doing
1005 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1006 not security fix but optimization.
1008 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added new config entry [Identity] to fork the server and run
1011 it as specific user and group. A patch from Bostik.
1013 * Imported Dotconf configuration library into lib/dotconf.
1014 This will be used to create the SILC configuration files later.
1015 It will appear in the distsribution after this commit.
1017 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * A big code auditing weekend happening. Auditing code for
1020 obvious mistakes, bugs and errors. Also, removing any code
1023 Removed files for being obsolete:
1025 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1026 inline in the file lib/silcutil/silcbuffer.h)
1028 o lib/silcutil/silcbufutil.c (the header has inline versions)
1030 Changed code to fix possible error conditions:
1032 o The buffer formatting routines now check that the destination
1033 buffer really has enough space to add the data. This applies for
1034 both buffer formatting and unformatting
1035 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1036 unformatting was changed to accomodate following rules:
1037 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1038 sent to the function while XXX_*STRING will not allocate or copy
1039 the data into the buffer. Instead it sets the pointer from the
1040 buffer into the pointer sent as argument (XXX_*STRING used to
1041 require that the pointer must be allocated already). This change
1042 makes this whole thing a bit more consistent and more optimized
1043 (note that the data returned in the unformatting with XXX_*STRING
1044 must not be freed now). The routines return now -1 on error.
1046 o Tried to find all code that use buffer_format and buffer_unformat
1047 and added return value checking to prevent formatting and
1048 especially unformatting errors and possible subsequent fatal
1051 o Changed ske->x and ske->KEY to mallocated pointers in
1052 lib/silcske/silcske.h. Fixed possible data and memory leak.
1054 o Added return value checking to all *_parse* functions. Fixed
1055 many memory leaks as well.
1057 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1058 so that buffer overflows would not happen. All code now also
1059 checks the return value as it can fail.
1061 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Added reconnection support to server if the normal server looses
1064 its connection to the router (for example if router is rebooted).
1065 The server performs normal reconnection strategy implemented
1066 to the server. Affected file silcd/server.c.
1068 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Added new packet type SILC_PACKET_SET_MODE that is used to
1071 distribute the information about changed modes (for clients,
1072 channels and clients channel modes) to all routers in the
1073 network. Updated the protocol specification accordingly.
1075 Added functions into silcd/packet_send.c and
1076 silcd/packet_receive.c: silc_server_send_set_mode,
1077 silc_server_set_mode.
1079 Added new files silcmode.[ch] into lib/silccore that implements
1080 the encoding and decoding of Set Mode Payload. Added new type
1081 SilcSetModePayload. Moved the definitions of different modes
1082 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1084 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Oops, a little mistake in server's connection authentication
1087 protocol. The protocol is not ended with FAILURE but with
1088 SUCCESS if the authentication is Ok. :) Affected file is
1091 * Implemented NICK_CHANGE notify handling in server in the file
1092 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1093 the local clients on the channel. After the changing nickname
1094 in router environment snhould work and the [<unknown>] nickname
1095 should appear no more.
1097 The silc_server_replace_id function that receives the Replace ID
1098 payload now sends the NICK_CHANGE notify type also in the file
1099 silcd/packet_receive.c
1101 * Changed WHOIS and IDENTIFY command to support the maximum amount
1102 of arguments defined in protocol specs (3328 arguments). This
1103 fixed a bug that caused problems when there were more than three
1106 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Added extra parameter, command identifier, to the
1109 silc_client_send_command so that explicit command identifier
1112 Changed that ID list routines uses specific command identifier
1113 when sending WHOIS/IDENTIFY requests to the server so that they
1114 can be identified when the reply comes back.
1116 Affected files lib/silcclient/command.[ch],
1117 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1119 * Added `sender' argument to silc_server_packet_send_to_channel
1120 to indicaet the sender who originally sent the packet to us
1121 that we are now re-sending. Ignored if NULL. Affected file
1122 silcd/packet_send.[ch].
1124 * Added some server statistics support in silcd/server_internal.h
1125 SilcServerStatistics structure and around the server code. Also
1126 send some nice statistics information when client is connecting
1129 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Fixed channel ID decoding in server's JOIN command reply in
1132 silcd/command_reply.c
1134 * Fixed braodcasting of replace ID payload to not to send it if
1135 we are standalone server in silcd/packet_receive.c.
1137 * Fixed all channel message sending routines to not to send
1138 packets to clients that has router set, since they are routed
1139 separately in the same function earlier. Affects file
1140 silcd/packet_send.c and all channel packet sending functions.
1142 * In USERS reply, res_argv[i] are not allocated, the table
1143 is allocated. Thus changed that free the table, not its
1146 * In server's whois_check and identify_check if the client is
1147 locally connected do not send any WHOIS commands - they are not
1150 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Fixed some minor bugs in client when sending WHOIS command. The
1153 arguments was in wrong order.
1155 * Removed statis function add_to_channel from server in
1156 silcd/command.c that was previously used with the joining but
1159 * Tested USERS command in router environment successfully with two
1160 routers, two servers and two clients.
1162 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Reorganized the USERS command and command reply in client library
1165 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1166 When the command is given by user we register a pending command
1167 callback that will reprocess the command after the reply has been
1168 received from the server. When reprocessing the packet we then
1169 display the information. Thus, the USERS information is displayed
1170 now in the command callback instead of in the command reply
1171 callback. The processing of the command is same as previously
1172 when server has sent the command reply in the JOINing process.
1174 * Added to USERS command in silcd/command_reply.c to join the client,
1175 we didn't use to know about, to the channel after we've created
1176 a client entry for it. Also, for clienet we did know already still
1177 check whether it is on the channel or not and add it if not.
1179 * Removed silc_server_command_join_notify as the function and its
1182 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Changed the client's pending command handling to the same as the
1185 server's pending command handling. It is also now possible to
1186 execute command reply functions from other command reply
1187 function as the function callbacks for commands and command
1188 replies are one and same. The pending commands are not static
1189 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1190 in client connection context. Thus, pending commands are server
1191 connection specific as it is convenient.
1193 Changed the function silc_client_command_pending and
1194 silc_client_command_pending_del and added new function
1195 silc_client_command_pending_check. Removed the
1196 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1199 * Added cmd_ident, current command identifier, to the client
1200 connection context in lib/silcclient/client.h to keep track on
1201 command identifiers used in command sending. Client's command reply
1202 function handling now supports the mandatory command identifiers.
1204 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1205 funtions in client to fully support pending command callbacks.
1207 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1208 as one of the arguments to the application in the command reply
1211 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1212 before first releasing SILC but came back. Now it is removed again
1213 and should come back nomore. The FORWARDED flag was used only
1214 by the JOINing procedure by forwarding the command packet to router.
1215 Now, the JOINing procedure has been changed to more generic (due
1216 to various router environment issues) and FORWARDED is not needed
1217 anymore for anything. The protocol specification is yet to be
1220 Now, removed silc_server_packet_forward from server and the flag
1221 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1223 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Renamed NAMES command to USERS command. The NAMES was named that
1226 due to historical reasons. Now it is renamed. Also, rewrote
1227 parts of the USERS command. The nickname list is not sent anymore
1228 by the server. Only Client ID and mode lists are sent in the USERS
1229 command. Changed this also to the protocol specification.
1231 The client now resolves the names and stuff after it receives
1232 the USERS list from the server when joining to the channel.
1234 * WHOIS and IDENTIFY commands has been changed to support multiple
1235 Client ID's per command. One can now search for multiple users
1236 in the network by sending only one WHOIS or IDENTIFY command.
1237 Changed the code and the protocol specifications.
1239 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1240 uses silc_server_command_whois_parse to parse the request. */
1242 * If normal server, do not parse the WHOIS and IDENTIFY requests
1243 before sending it to the router. Saves some time.
1245 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Fixed JOIN command on client library. Wrong number of arguments
1248 used to crash the client.
1250 * Added silc_server_channel_has_global function to check whether
1251 channel has global users or not.
1253 * Added silc_server_channel_has_local function to check whether channel
1254 has locally connected clients on the channel.
1256 * The silc_server_remove_from_one_channel now checks whether the
1257 channel has global users or not after given client was removed from
1258 the channel. It also checks whether the channel has local clients
1259 on the channel anymore. If it does not have then the channel entry
1260 is removed as it is not needed anymore.
1262 * The silc_server_notify now checks on JOIN notify whether the joining
1263 client is one of locally connected or global. If it is global then
1264 the channel has now global users on the channel and that is marked
1265 to the channel entry. Also, it now saves the global client to
1266 global list who is joining and JOINs it to the channel. This is
1267 for normal server, that is.
1269 Changed silc_server_send_notify_on_channel,
1270 silc_server_packet_relay_to_channel and
1271 silc_server_packet_send_to_channel check if we are normal server
1272 and client has router set (ie. global client) do not send the
1273 message to that client, as it is already routed to our router.
1275 * Implemented LEAVE notify type handling in silc_server_notify
1278 * Tested LEAVE command in router environment successfully. Tested
1279 with two routers, two servers and two clients.
1283 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1285 * Implemented SIGNOFF notify type handling in silc_server_notify
1288 * silc_server_remove_id now removes the client entry from all channels
1289 it has joined and thusly sends SIGNOFF notify type.
1291 * Rewrote the NAMES list generation in server by removing two excess
1292 loops. The lists are created now inside one loop.
1294 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * silc_server_remove_channel_user checks now also global list
1297 for channel and client.
1299 * silc_server_new_channel_user checks now both local and global
1300 list for channel and client. Fixed a bug in client id decoding.
1301 Used to decode wrong buffer.
1303 * silc_server_channel_message checks now both local and global
1304 list for channel entry.
1306 * Tested channel joining (hence JOIN) in router environment
1307 successfully. Tested with two routers, two servers and two
1310 * Tested channel message sending in router environment successfully.
1312 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Added silc_server_save_channel_key into server.[ch] to save the
1315 received channel key in Channel Key payload processing. It is
1316 also used in JOIN command reply handling.
1318 Equivalent function silc_client_save_channel_key added into
1319 client.[ch] into client library.
1321 * Changed JOIN command reply to send information whether the channel
1322 was created or not (is existing already) and the channel key
1323 payload. Changed protocol specs accordingly.
1325 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1326 the request was sent by ID and not by nickname. Crashed on
1329 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1331 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1332 now correctly save the received data.
1334 * silc_server_free_sock_user_data now notifies routers in the
1335 network about entities leaving the network.
1337 At the same time implemented functions silc_server_remove_id
1338 and silc_server_send_remove_id to receive and send REMOVE_ID
1339 packets. The packet is used to notify routers in the network
1340 about leaving entities. The ID removed will become invalid in
1343 * Added function silc_idlist_del_server into server. Removes and
1344 free's server entry from ID list.
1346 * silc_server_private_message function now checks, if we are router,
1347 that the destination ID really is valid ID, naturally.
1349 * In router when NEW_ID packet is received (for new client) the
1350 hash of the Client ID is saved in the ID Cache but the
1351 client->nickname is set to NULL, instead of putting the hash
1354 IDENTIFY command now also checks that client->nickname must be
1355 valid. If it is not if will request the data from the server who
1356 owns the client. Added new function
1357 silc_server_command_identify_check.
1359 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1360 to set the command to already allocated Command Payload.
1362 * Tested private message sending in router environment with two
1363 routers, two servers and two clients. Fixed minor bugs and now
1366 * Fixed segfault from client's NAMES command. Used to crash if
1369 * Forwarded packets must not be routed even if it is not destined
1370 to the receiver. Changed server code comply with this.
1372 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Added `require_reverse_mapping' boolean value to ServerParams
1375 structure. If TRUE (not default) the server will require that
1376 the connecting host has fully qualified domain name.
1378 If the reverse mapping is not required and hostname could not be
1379 found the IP address is used as hostname.
1381 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Implemented version string checking to both client and server.
1384 The check is incomplete currently due to the abnormal version
1385 strings used in development version of SILC.
1387 * Changed all command functions in server to use the new
1390 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Changed char *data to unsigned char *data in ID Cache system to
1393 support binary data as ID Cache data. Changed code to support
1394 binary data in lib/silccore/idcache.c.
1396 * Renamed silc_server_packet_relay_command_reply to
1397 silc_server_command_reply as it is normal packet receiving
1398 function. Rewrote the function to accept command replys for
1399 servers and not only for clients.
1401 * Mark remote router always as registered server if we are connecting
1402 to it. Otherwise, commands sent by the router to us are ignored.
1404 * All ID List find routines now returns the ID Cache Entry pointer
1405 as well if requested.
1407 * WHOIS command works now in router environment, tested with two
1408 routers, two servers and two clients.
1410 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1411 in router environment (as it is almost equivalent to WHOIS) but
1412 hasn't been tested thoroughly. Added new functions:
1414 silc_server_command_identify_parse
1415 silc_server_command_identify_send_reply
1416 silc_server_command_identify_from_client
1417 silc_server_command_identify_from_server
1419 * Disabled route cache adding because adding two different ID's with
1420 same IP replaces the old cache entry thus giving wrong route.
1421 The entry->router->connection is always the fastest route anyway
1422 so route cache may not be needed. Of course, new routes maybe
1423 established after receiving the ID when the entry->router->connection
1424 might not be anymore the most optimal.
1426 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Add route cache for received ID for fast routing.
1430 * Added silc_server_packet_route to route received packet on router
1431 that is not destined to us.
1433 * Renamed silc_server_get_route to silc_server_route_get.
1435 * Added id_string and id_string_len fields into SilcServer to
1436 include encoded ServerID for fast comparing without excess
1437 encoding of the ID's.
1439 * Cleaned up WHOIS command on server side. Added following static
1442 silc_server_command_whois_parse
1443 silc_server_command_whois_check
1444 silc_server_command_whois_send_reply
1445 silc_server_command_whois_from_client
1446 silc_server_command_whois_from_server
1448 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1449 arguments in command replies. All command functions should be
1450 updated to use this macro.
1452 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Minor typo fixes on command reply handling on server.
1456 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Added silc_server_command_add_to_channel internal routine to add
1459 the client to the channel after router has created the channel and
1460 sent command reply to the server.
1462 * Added generic silc_server_send_command to send any command from
1465 * Use static buffer with ID rendering instead of duplicating data.
1467 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Fixed a channel user mode bug when joining to a channel server gave
1470 everybody channel founder rights, oops.
1472 * We mark ourselves as the router of the incoming server connection
1473 if we are router ourselves. This way we can check in some packet
1474 sending functions whether it is locally connected server. For
1475 incoming router connections we put NULL.
1477 * For router sending packets locally means now always sending the
1478 packet cell wide; to local clients and local servers. For normal
1479 server sending packet locally means sending it to only local
1482 * Fixed the JOIN command to really work in router environment. If the
1483 channel is created it is always created by the router. Router is
1484 also responsible of making the initial joining to the channel,
1485 sending JOIN notify to the sending server and distributing
1486 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1487 does not exist server doesn't do anything else but forward the
1488 command to the router which performs everything.
1490 * Added silc_server_send_channel_key function to send the Channel Key
1493 * Added silc_server_create_channel_key to create new channel key. The
1494 channel key is now re-generated everytime someone joins or leaves
1495 a channel, as protocol dictates. Note: channel->key_len is the
1498 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1501 packet_receive.[ch] to separate packet sending and receiving
1502 routines. The server.[ch] now includes everything else including
1503 actual packet processing (writing and reading data) and other
1506 Renamed silc_server_private_message_send_internal to
1507 silc_server_send_private_message. The routine is still though
1508 used only to relay private messages as server does not send
1509 private messages itself.
1511 Renamed silc_server_new_channel to silc_server_create_new_channel
1512 and added new function sicl_server_new_channel that handles the
1513 incoming New Channel packet. Added also new sending function
1514 silc_server_send_new_channel to send New Channel Payload.
1516 * Added new function silc_server_notify to process incoming notify
1517 packet to the server/router. Server may then relay the notify
1518 to clients if needed.
1520 * Added new function silc_server_new_channel_user to process incoming
1521 New Channel User packet. Router will redistribute the packet and
1522 send JOIN notify to its local clients and locally connected servers
1523 if needed. Normal server will send JOIN notify to its local client
1524 on same channel when received this packet. Added also corresponding
1525 sending function silc_server_send_new_channel_user to sent the
1528 * Added boolean route argument to send_notif_to_channel and
1529 packet_send_to_channel functions to attempt to route the packet
1530 if it is TRUE and send only locally if it is FALSE.
1532 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1534 * silc_server_replace_id now broadcasts the received replace ID
1535 packet if it is not broadcast packet already. The router must
1536 broadcast to inform other routers about changed ID.
1538 * Added backpointer to server's router into SilcServer context in
1539 silcd/server_internal.h.
1541 * Fixed silc_server_packet_broadcast to send correct broadcast
1544 * The channel key is now distributed to the local client as soon
1545 as it is received from the router (in router environment) so that
1546 no other packet may be sent for the channel until client has
1549 * silc_server_remove_channel_user now broadcasts the received
1550 Remove Channel User packet if it is not broadcast packet already.
1551 The router must broadcast to inform other routers about removed
1554 * Added users field into SilcPacketContext that is a reference count
1555 of the context. One can increase the reference count by calling
1556 silc_packet_context_dup which is now changed to just increase the
1557 reference count instead of duplicating the data. The reference
1558 count is decresed by calling silc_packet_context_free that will
1559 free the data after the reference count hits zero.
1561 For now on the packet context and everything allocated into it
1562 (including the raw packet from network) must be freed by calling
1563 the new silc_packet_context_free function. Added also new function
1564 silc_packet_context_alloc that must be used now to allocate the
1565 context. This also means that if a routine is asynchronous from
1566 silc_[client/server]_packet_parse_type the packet context must
1567 be duplicated by calling silc_packet_context_dup. Otherwise it
1568 gets free'd after silc_[client/server]_packet_parse_type returns.
1569 Also, one must remember that if packet is duplicated then its
1570 reference count must be decresed by calling the free function as
1571 many times as it was duplicated.
1573 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1574 from both client and server.
1576 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Made joining to a channel working in router environment.
1580 * Cleaned up JOIN command on server side and create function
1581 silc_server_command_join_channel internal routine to make the
1584 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Changed silc_command_pending list to SilcDList. Also, added
1587 `ident' field to SilcServerCommandPending structure to identify
1588 the reply and to call correct callback.
1590 Added silc_server_command_pending_check function to replace the
1591 corresnponding macro. The silc_command_pending list is not
1594 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1595 to set identifier to previously allocated Command Payload. It
1596 is used to set identifier for command when resending Command
1599 * Added silc_command_payload_encode_payload to encode Command
1600 Payload buffer from SilcCommandPayload structure.
1602 * Added silc_argument_payload_encode_payload to encode Argument
1603 payload buffer from SilcArgumentPayload structure.
1605 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Changed WHOIS command to support router connection on server side.
1608 The whois request is always sent to router unless the server is
1609 standalone server. After server has received the reply from the
1610 router will it send the reply to the client.
1612 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1613 broadcast received broadcast packet. The function is used only
1614 by router. The broadcast packet is always sent to the router's
1617 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1618 render given ID to printable string, for log files for example.
1620 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Made basic router to router connections working. At least they
1623 can now connect to each other but nothing really works the way
1624 they are supposed - yet.
1626 * Added new initiator token to RouterConnection configuration
1627 file in silcd/serverconfig.[ch]. It is used to tell whether we
1628 are the initiator to the remote router or whether we'll expect
1629 the other end to connect.
1631 * Moved registering of listener task to silc_server_init, hence
1632 the server starts listenning as soon as it is run, even if it
1633 does not have connections to other routers. Let's see how well
1636 * Changed default connection retry timeouts for more suitable in
1639 * Removed cipher and such arguments from silc_idlist_add_client
1640 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1641 Added new function silc_idlist_add_data to add the keys and stuff
1644 * Added SilcIDListData structure and added it to SilcClientEntry
1645 and SilcServerEntry as their first field in the structure. This
1646 way we can explicitly cast the ID entries to the SilcIDListData
1647 structure and get common data for the entries. In past, we had
1648 to first check what type of connection it is and then cast it to
1649 correct ID entry type. Now, we can directly cast the opaque
1650 pointer to the SilcIDListData (no matter what ID entry it actually
1651 is) and get the data needed.
1653 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1656 in some circumstances even if threre were timeout tasks, though not
1657 IO tasks, but tasks anyway. Now fixed.
1659 * Defined SilcServerConnection structure to hold connection specific
1660 stuff about directly connected servers and routers. The definition
1661 is currently in silcd/server_internal.h. I thought about having
1662 a bit more important role fro this struct but for now it is used
1663 only when connecting to other server (or router actually).
1665 * Added connecting retry support in server when connecting to
1666 router(s). The retry feature implement exponential backoff
1667 algorithm. Also, added SilcServerParams structure to hold default
1668 parameters for server. For now, it include these retry settings
1669 and are hard coded. After server is moded to be as Silc Server
1670 Library this structure will be more important.
1672 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Changed client librarys channel->clients table to SilcList and
1675 changed code accordingly.
1677 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1679 * Changed client's channel table to SilcList and changed code
1680 accordingly. Also changed SilcChannelClientEntry to include back-
1681 pointer to the channel so that client entry can use that structure
1682 as list as well and we have fast cross-reference to the channel.
1683 This change dramatically decreased the complexity of channel
1684 handling with client entry and vice versa (removed one extra
1685 loop when searching for channel entry from many functions).
1687 * Changed server->sim from table to SilcDList and changed code
1690 * NAMES command can now be used from user interface. It will show
1691 the user list on the channel, neatly.
1693 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1694 Code now saves realname of the user if it becomes available.
1696 * Renamed configure.in to configure.in.pre and made ./prepare
1697 script to automatically add correct version string to
1698 configure.in which it creates from configure.in.pre.
1700 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * NAMES command reply now shows users mode with the nickname when
1705 * Moved silc_client_ch[u]mode[_char] functions from
1706 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1707 place sucks, they are utility functions and should be in some
1710 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1712 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1715 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Added TRQ (efficient deque and list library) into lib/trq. This is
1720 a very good list library that is currently used in the SILC. Defined
1721 SilcList API over the library because I didn't like the API very
1722 much. See lib/trq/silclist.h for the API and examples of how to
1723 use the API. Fixed various places in the code to use the new
1724 SilcList API. The SilcList is meant for lists that has a structure
1725 already defined as a list. It is not suitable to add just some
1726 context to the list (in TRQ, the context is the list actually).
1728 So, I defined SilcDList that can be used for the purpose where
1729 predefined list structure does not exit. This can be used as
1730 such list. Now some context just can be added to the SilcDList.
1731 Currently this list is not used in the SILC just yet, though there
1732 are a lot places where this can replace dynamically allocated
1733 tables and I will fix these places, later, to use SilcDList.
1734 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1735 and use TRQ internally).
1737 Also fixed some annoying warning messages that the original TRQ
1738 code generated. Also minor changes to TRQ's Makefile.in.
1740 * Added support for querying by Client ID to both WHOIS and
1741 IDENTIFY commands into server, as required by the protocol.
1743 * Removed method function pointers from SilcBuffer structure. They
1744 weren't used to anything and just increased the context size for
1745 no good reason. This change also made silc_buffer_alloc and
1746 silc_buffer_free functions inline functions.
1748 * Disabled command flooding detection support until it's fixed so
1749 that it accepts commands in but does not execute them more than once
1752 * Added silc_net_localhost(), to return local hostname, into
1753 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1754 that must be initialized before calling silc_client_init.
1756 * Added new function: silc_server_send_notify_on_channels to send
1757 notify messages to all channels client has joined. It is assured
1758 that the message is sent only once per client.
1760 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1761 lib/silcutil/silcutil.[ch] as silc_format function. The new
1762 function is generic and is used by server as well, not only by
1763 the logging routines.
1765 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1766 the provided version string was not acceptable. Added new function:
1767 silc_ske_check_version into lib/silcske/silcske.h. The function
1768 must be implemented by the application (client or server) and it
1769 does not reside in the SKE library. The function checks the version
1770 string remote end sent.
1772 * Added back pointers (to opaque context and to SilcSocketConnection)
1773 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1775 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1776 duplicate packet context structure.
1778 * Changed `notify' client operation to send same arguments as client
1779 receives from server except for ID's. ID's are mapped to correct
1780 ID entry and that is returned. Also, if channel entry is not sent
1781 by server but the notify is for channel the channel entry is sent
1782 to application (otherwise application doesn't know that it is for
1783 channel (library gets it from packet's Destination ID)).
1785 * Added silc_client_remove_from_channels into client library to
1786 remove a client from all channels it has joined to. Used when
1787 received SIGNOFF notify from server. Added also new function
1788 silc_client_replace_from_channels to replace old ID entry with
1789 new ID entry on all channels. Used when received NICK_CHANGE
1792 * Fixed ID Cache list handling in silc_idlist_get_client in
1793 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1794 to get (or query) client by ID.
1796 * Updated TODO list.
1798 * Added connection authentication status message defined by the
1799 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1800 support for these into the code in client and server side.
1802 * Added generic function silc_client_send_command to send any command
1803 with variable argument list. Application should use this function
1804 to send commands if the command functions provided by the library
1805 does not suite for the application's user interface needs.
1807 * Added new `failure' client operation. Application is notified about
1808 received failure packet if client is executing a protocol. In this
1809 case the protocol's execution has failed.
1811 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1812 is required by the protocol.
1814 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1815 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1818 * Added status flag to SilcSKE object to indicate realtime status
1819 of the SKE protocol.
1821 * Application receives now exactly same command reply arguments as
1822 the library receives from server. However, if ID is received the
1823 corresponding ID entry is returned to the application (eg. Client
1824 ID is mapped to correct SilcClientEntry entry and that is returned).
1825 Changed command_reply client operation due to this change.
1827 * Changed all ID's in commands and in command replys as ID Payloads.
1828 Change affected both client and server side codes.
1830 All ID's sent in SILC network (with execption of ID's in SILC
1831 Packet header) are sent in ID Payload to support variable length
1834 * Server now notifies nick changes and notifies all clients on
1835 the channels about the new nickname (about the new Client ID,
1838 * Implemented CMODE command to change channel modes. Supports all
1839 channel modes defined by the protocol specs except ban and invite
1840 lists. (Also, private channel key mode is supported but support for
1841 setting private channel key in client is missing, thus, this mode
1842 has no effect on client side (except that server requires that the
1843 client uses private channel key and normal channel traffic does not
1846 Also, invite mode works per se, but INVITE command does not work
1847 yet correctly, so you can set channel as invite only channel but
1848 inviting clients to the channel does not work (it is yet to be
1849 thought what's the best way to do it).
1851 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1852 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1853 Implemented CUMODE command to change user's mode on the channel.
1854 Supports all modes defined by the protocol specs.
1856 * Added NAMES command reply to return users modes on the channel.
1858 * Removed unnecessary and slow ciphers from lib/silccrypt.
1860 * Set SO_KEEPALIVE option to connection sockets by default.
1862 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1864 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1865 redefined the Notify Payload into protocol specs.
1867 * Added silc_id_payload_parse_id to get ID directly from raw
1870 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1873 accept searching by Client ID as well.
1875 * Added support for LEAVE and SIGNOFF notify types in client library.
1877 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1878 to parse ID Payload from raw data.
1880 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Added flags parameter into silc_ske_assemble_security_properties
1883 function in lib/silcske/silcske.[ch].
1885 * Changed notify client operation to fit better for notify messages
1886 sent by server. The notify payload received from server is now
1887 passed to the application (after parsing it to SilcNotifyPayload).
1888 It is application's responsibility to retrieve the arguments
1889 from the payload and show the message the way it wants. The message
1890 sent by server is implementation specific.
1892 * Changed public keys to comply with the protocol specification.
1893 Old public keys are not supported anymore and are not compatible.
1895 * Removed nickname from Channel Payload as the latest draft removed
1896 it. The client must resolve the nickname from the NAMES command
1897 reply received when it joined the channel.
1899 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1901 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Fixed some errors in protocol specification drafts.
1905 * Created lib/silccore/silcnotify.c to implement Notify Payload
1906 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1907 generic payloads described by protocol specifications. The file
1908 includes implementations for ID Payload and Argument Payload.
1910 * Changed Command Payload implementation to use the new Argument
1911 Payload. Changed command_xxxx_payload to command_payload_xxxx
1912 to comply with SILC coding conventions.
1914 * Added suppport for Argument Payload handling in Notify Payload
1915 implementation as protocol requires it. Added the new support
1916 into server and client lib as well.
1918 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Added support for multiple nicknames on same channel. [n] is
1921 added locally to the nickname if there are more than one same
1922 nicknames on the channel.
1924 * Server now sends all nicknames that matched WHOIS request.
1925 Client also shows the list received from server.
1927 * Added TOPIC command to client side. User can now set and show
1928 current topic on channel.
1930 * Added MOTD command to client and server. Also, server sends the
1931 motd when client connects to the server.
1933 * Changed version strings to comply ISO 8601.
1935 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Fixed protocol error handling in client library. It should now
1938 cope even if the SKE fails for some reason.
1940 * Made new protocol specification drafts for submitting to IETF.
1942 * Implemented TOPIC command to server in silcd/command.c.
1944 * Added two new notify types into lib/silccore/silcnotify.h:
1945 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1946 notify nickname change and topic setting/change on a channel.
1948 * API change of command_reply operation in client library. The
1949 application gets now the status type received from server as well.
1951 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1955 * Cras fixed and optimized the packet handling even further and
1956 it should work now. Minor change to the prototype of function
1957 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1959 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Added new function into lib/silcutil/silcschedule.[ch]:
1962 silc_schedule_with_fd to select() a specified fd. The function
1963 returns after timeout expires or data arrives or goes. The
1964 function is used by packet routines to wait that all data is
1965 received from network.
1967 * Fixed data reading from network in lib/silccore/silcpacket.c.
1968 The code now assures that all data is read from the fd and then
1969 continues packet processing. This was a bug fix since the code
1970 used to drop some data in some circumstances.
1972 * Added new function into lib/silcclient/client.[ch]:
1973 silc_client_start_key_exchange to start key exchange after
1974 connection has been established to server. The code internally
1975 now uses this funtion but its main purpose was to provide it
1976 for applications that perform their own connecting. After
1977 application has created a connection it merely calls this
1978 function to start the key exchange between client and server.
1979 The library takes care of everything else after that.
1981 Updated also lib/silcclient/README to explain the usage of
1984 * Do not send to application information that connection has
1985 been established. Application gets notified it by connect
1988 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Applied cras's patch to add silc_schedule_one function. The
1991 function runs scheduler once and returns.
1993 * Fixed the scheduler after cras messed it up. The timeout
1994 handling works now as it's supposed to work.
1996 * Added into lib/silccore/ silcnotify.h to include notify
1997 message types support. Changed silc_server_send_notify*
1998 functions, in server.[ch], to support those new notify types.
1999 Added the support for the notify types into client library,
2000 as well. Added new notify client operation into ops.h in
2003 * Changed silc_server_packet_send_to_channel to send normal
2004 packets instead of just channel message packets. The function
2005 is now used to send the notify packets to channels. It is not
2006 used to send channel message packets anymore, as server never
2009 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2010 va_arg()s as it seems to require it nowadays. I guess, if SILC
2011 is compiled with older va_arg() the new code should work anyway.
2013 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Splitted core library. Core library (lib/silccore) includes
2016 now only SILC protocol specific core (and common) components.
2017 Created new utility library (lib/silcutil) that includes more
2018 generic purpose stuff. The stuff for util library was taken
2019 from the old core library. This was minor and easy split.
2021 * Created SILC Client Library (lib/silcclient) that includes
2022 implementation of the SILC client without user interface. This
2023 was major move from silc/ directory. The code has been changed
2024 so that it is transparent towards the user interface. The
2025 silc/ directory includes now the same user interface as before
2026 and it uses the new client library. Read lib/silcclient/README.
2027 Basicly, the client library performs everything else related
2028 to SILC except user interface handling. Also, configuration
2029 files are considered to be part of user interface and library
2030 does not handle them.
2032 This change also changed a lot of structures, function naming etc.
2033 Most important change was that SilcClientWindow object was
2034 renamed to SilcClientConnection in the client library. Created
2035 also new file lib/silcclient/ops.h. Also added new files
2036 silc/local_command.[ch] and silc/client_ops.[ch].
2038 All these changes were made to make it easier for user interface
2039 designers to create what ever user interface for the SILC client
2042 It is also expected that the server will be moved to lib
2043 directory as well and SILC Server Library will be created;
2044 sometimes in the future.
2046 * Removed Local commands from lib/silccore/silccommand.h as
2047 they are application specific and new client library does not
2048 handle any of those anymore.
2050 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2051 old client implementation in silc/.
2053 * Added support for callback functions in SILC_LOG_* macros.
2054 Application can now set its own callbacks that will be called
2055 instead of using the default functions that will always print
2056 the debug messages to stderr (or stdout). Also, debugging can
2057 now be disabled by setting silc_debug to FALSE and re-enabled by
2058 setting it to TRUE. Note, that logging will still work even
2059 if debugging is disabled.
2061 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2062 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2063 silc_log_reset_debug_callbacks.
2065 * To enable debugging in silc client one must give now -d
2066 option on command line.
2068 * Changed silc_schedule_init to automatically allocate task queues
2069 if they are not allocated before calling it.
2071 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Added GMP 3.1 into math library.
2075 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2078 a channel in SILC network. The packet is used by servers and
2079 routers to notify other routers that user has left a channel.
2080 This little feature was missing until now. Added the feature
2081 to protocol specification as well.
2083 Added functions: silc_server_send_remove_channel_user and
2084 silc_server_remove_channel_user into server.[ch].
2086 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2087 lib/silccore/silcpacket.h. However, they are not implemented
2090 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Fixed joining to a channel and sending channel messages
2093 between server and router. The channel message sending should
2094 now work inside a cell.
2096 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Fixed the private message sending between server and router.
2099 The private message sending should now work inside a cell.
2101 * Added silc_server_replace_id into server.[ch] to replace
2102 existing ID in the SILC network.
2104 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2105 and silc_idlist_replace_server_id into idlist.[ch] in server.
2107 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Fixed the server to server connections. Server can again now
2110 connect to router. Router to router connections probably does
2113 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Added dynamic protocol registering support. Now protocols can
2116 registered and unregistered on the fly. Patch by cras.
2118 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Added lib/contrib directory to hold routines that some platforms
2121 don't have but are needed by SILC.
2123 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2124 into lin/contrib to provide getopt() and getopt_long() for
2125 those who don't have it.
2127 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Added AWAY command to client. When away message is set and
2130 client receives a private message packet the client automatically
2131 replies to the sender with the away message.
2133 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2134 bug seemed to be the cause of recent problems when compiling
2137 * Added version detection support to SKE protocol specification
2138 and added the new changes to the SKE implementation as well.
2139 There were other minor changes in the SKE protocol as well.
2141 Many changes in lib/silcske/silcske.[ch] and in
2142 lib/silcske/payload.[ch].
2144 * Added ^U functionality, clear input line. Patch from cras.
2146 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Mainly small bugfixes on core library. Fixed some debugging
2149 logging and buffer overflow in silclog.c.
2151 * Updated config.sub and config.guess on the distribution tree.
2153 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Added command lagging support in server. Client may execute
2156 commands now only once in two seconds.
2158 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Optimized packet reception. MAC computation and checking is now
2161 also more optimized. A lot previously duplicated code is now
2162 used as generic by both client and server.
2164 * Fixed key pair generation in clientutil.c
2166 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Added into lib/silccore/silcbufutil.[ch] new function;
2169 silc_buffer_realloc.
2171 * Moved generic packet sending/encryption functions to
2172 lib/silccore/silcpacket.[ch] from client and server. Some
2173 rewriting of the functions.
2175 * Moved all generic packet reception/decryption functions to
2176 lib/silccore/silcpacket.[ch] from client and server. The
2177 packet processing is now much cleaner in both client and server.
2178 These were major changes in both client and server.
2180 * Created many common functions in server to do packet sending.
2181 Previously code were duplicated a lot, this has been removed
2184 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Rewrote major parts of the ID cache system. Don't know
2187 whether it is better now or not but at least the API is more
2190 * Major rewrite on ID cache stuff on client because of the ID
2191 cache API changes. Added idlist.c to client.
2193 * Also major rewrite on ID cache stuff on server as well.
2194 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2195 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2196 in hand, instead they are all put into the ID cache system now.
2197 All server_idlist_* routines uses ID cache now instead of
2198 traversing its own lists (those lists does not exist anymore).
2199 SilcIDList though still exists. Also, SilcXXXEntry's are
2202 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Finally made the SKE implementation compliant to the protocol
2205 specification. All mp integers are now binary encoded as
2206 opposed being HEX encoded.
2208 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2211 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2212 functions: silc_[encode/decode]_pem. Also added function
2213 silc_encode_pem_file to PEM encode with newlines ('\n') for
2216 * SILC public keys are now encoded either PEM or binary. Same
2217 option is for private keys as well. By default private keys
2218 are binary encoded and public keys PEM encoded. Silly HEX
2219 encoding were removed.
2221 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2222 function to create fingerprints.
2224 * Fixed a bug in SHA1; does not change the original data anymore.
2226 * Partly implemented INFO command on client and server side.
2227 Fixed CLEAR command. Changes to SERVER command; show current
2228 server(s) when giving command without arguments. Added
2229 VERSION command to client.
2231 * Added check to server that unregistered connections cannot
2232 execute commands (unless it is specificly allowed).
2234 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Fixed screen refresh.
2238 * Fixed channel joining bug from client. On some circumstances
2239 client tried to join to a channel it had already joined.
2241 * Added public key verification process into client's protocol.c.
2242 The client now verifies the public key from user and saves
2243 it into ~./silc/serverkeys/ directory.
2245 Added into: clientutil.[ch]: silc_client_verify_server_key.
2247 * Changed SKE protocol's silc_ske_initiator_finish function
2248 to accept callback function that verifies the received public
2249 key. Removed old silc_ske_verify_public_key function.
2251 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2254 silc_pkcs_private_key[_data]_set.
2256 * Made the password and public authentication more cleaner in
2257 server's protocol.c.
2259 * Removed historic and obsolete protocol `channel_auth' from
2260 both client and server.
2262 * Removed wrong way of sending command status messages from
2263 server to client in server's command.c. The old way violated
2264 protocol specification.
2266 Changes to silccore/silccommand.[ch]: removed
2267 silc_command_encode_status_payload -> not needed anymore,
2268 changed silc_command_encode_payload_va to accept extra
2269 argument on variable argument list. The argument type must
2270 now be provided to the function. Also, added new function:
2271 silc_command_encode_reply_payload_va which is same as
2272 normal command_encode_payload_va except command status type
2273 is provided as extra argument.
2275 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added ~./silc directory handling. The directory includes the
2278 public and private keys for the client.
2280 Added silc_client_check_silc_dir, silc_client_create_identifier
2281 and silc_client_load_keys.
2283 * Implemented SILC protocol compliant public key. Added public
2284 and private key saving to and loading from files.
2286 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2287 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2288 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2289 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2290 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2292 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2293 silc_pkcs_load_[public/private]_key.
2295 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Added silc_server_get_route (route.[ch]) to get connection
2298 data for the fastest route for given ID.
2300 * Implemented INVITE command on client and server. The command
2301 were re-defined in the SILC Protocol Specification and the
2302 implementation now complies with the specification.
2304 * Implemented PING command on client and server.
2306 * Implemented NAMES command on client and server. The server side
2307 supports currently only normal server not router server yet.
2308 Some changes to NAMES definition in SILC protocol specification.
2310 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Implemented LEAVE command on client and server.
2314 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2315 again. This change was made to the protocol as well. Server
2316 should not violate the protocol specification anymore.
2318 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2321 was tested. SOCKS4 was not but should work anyway.
