1 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented WHOWAS command to the server. Added the functions:
5 silc_server_command_whowas_parse,
6 silc_server_command_whowas_send_reply,
7 silc_server_command_whowas_from_client and
8 silc_server_command_whowas_from_server
10 * Added <Client ID> argument to the WHOWAS command reply. Updated
11 the protocol specs accordingly.
13 * Implemented WHOWAS command and command_reply to the client
16 Implemented the WHOWAS printing on the user interface.
18 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Added new argument to the WHOWAS command reply, the real name.
21 It is an optional argument. Updated the protocol specs.
23 * Added SilcIDCacheDestructor callback that is registered when
24 the SilcIDCache is allocated. The callback is called when
25 an cache entry in the ID Cache expires, or is purged from the
26 cache. Added into lib/silccore/idcache.[ch].
28 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
29 to destruct the client entries when the cache entry expires.
30 Other ID Cache's in server and in the client library ignores
33 * If the ID Cache entry's `expire' field is zero then the entry
34 never expires. Added boolean `expire' argument to the
35 silc_idcache_add function in the lib/silccore/idcache.[ch].
36 If it is TRUE the default expiry value is used.
38 * Added silc_server_free_client_data_timeout that is registered
39 when client disconnects. By default for 5 minutes we preserve
40 the client entry for history - for WHOWAS command.
42 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Added support to the server to enforce that commands are not
45 executed more than once in 2 seconds. If server receives
46 commands from client more frequently, timeout is registered
47 to process the commands. Affected file silcd/command.c.
48 Added new function silc_server_command_process_timeout.
50 * Changed NICK_NOTIFY handling in client library to check that
51 if the client's nickname was changed, so there is no need to
52 resolve anything from the server.
54 * Removed error printing from the WHOIS and IDENTIFY commands.
55 If error occurs then it is ignored silently in the client library.
56 The application, however, may map the received error to
57 human readable error string. The application currently maps
58 the NO_SUCH_NICKNAME error to string.
60 * Made the command status message public to the application. Moved
61 them from lib/silcclient/command_reply.c to
62 lib/silcclient/command_reply.h. The application can map the
63 received command status to the string with the
64 silc_client_command_status_message function.
66 * Added check to the server to check that client's ID is same
67 as the Source ID in the packet the client sent. They must
70 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Added dist-bzip hook to the Makefile.am to make bzip2
73 compressed distributions.
75 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
77 * Server now enforces the maximum length for the nickname and
78 the channel as protocol specification dictates. 128 bytes for
79 nickname and 256 bytes for channel name.
81 * Moved the WHOIS printing to the application. The client libary
82 does not print out the WHOIS information anymore, the application
83 must do it. Renamed silc_client_command_reply_whois_print to
84 the silc_client_command_reply_whois_save.
86 The client's idle time is also sent to the application now, and
87 the idle is shown on screen.
89 * Added silc_client_command_reply_identify_save to save the
90 received IDENTIFY entries.
92 * Do not check for channel private keys in message sending and
93 reception if the channel does not have the PRIVKEY mode set.
94 Affected file lib/silclient/client_channel.c.
96 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
99 just surfaced after chaning the JOIN procedure.
101 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Added silc_client_get_clients_by_list to get client entries
104 from Client ID list, that is returned for example by JOIN
105 and USERS command replies. The application should use this
106 function for example when JOIN command reply is received to
107 resolve the clients already on the channel (library does not
108 do that anymore as USERS command reply is not used in the JOIN
109 procedure anymore). Affected files lib/silcclient/silcapi.h and
110 lib/silcclient/idlist.c.
112 * JOIN command reply and USERS command reply returns now SilcBuffer
113 pointers instead of unsigned char pointers when returning
114 the client list and mode list.
116 * Added <Client ID> argument to the JOIN command reply, mainly
117 for the server to identify for which client the command was
118 originally sent. Updated protocol specs accordingly.
120 * Added SilcDlist private_key pointer to the SilcChannelEntry
121 in the client to support the channel private keys. Affected
122 file is lib/silcclient/idlist.h.
124 * Added SilcChannelPrivateKey argument to the function
125 silc_client_send_channel_message so that application can choose
126 to use specific private ke if it wants to. If it is not provided,
127 the normal channel key is used, unless private keys are set.
128 In this case the first (key that was added first) is used
129 as the encryption key.
131 * Implemented the support for channel private key handling.
132 Implemented the following functions:
134 silc_client_add_channel_private_key,
135 silc_client_del_channel_private_keys,
136 silc_client_del_channel_private_key,
137 silc_client_list_channel_private_keys and
138 silc_client_free_channel_private_keys
140 Affected file lib/silcclient/client_channel.c.
142 * Added the support for the private keys in the channel message
143 sending and encryption and in the message reception and
144 decryption. Affected funtions are
145 silc_client_send_channel_message and silc_client_channel_message.
147 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Added SKE's key verify callback to the client library's
150 KE protocol context. Affected files lib/silcclient/protocol.[ch].
152 * Removed the statement that server (or router) must send USERS
153 command reply when joining to the channel so that the client
154 knows who are on the channel. Instead, the client list and
155 client's mode list is now sent in the JOIN command reply to the
156 client who joined channel. This is better solution.
158 * Added function silc_server_get_users_on_channel and function
159 silc_server_save_users_on_channel to the silcd/server.[ch].
161 * Removed function silc_server_command_send_users from the
164 * Do not show topic on the client library anymore. The topic is
165 sent in the command reply notify to the application and the
166 application must show the topic now.
168 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Added client searching by nickname hash into the IDENTIFY and
171 WHOIS commands in the server as they were clearly missing from
172 them. Affected file is silcd/command.c.
174 * Fixed a bug in private message receiving in the client library.
175 The remote ID was freed and it wasn't supposed, now it is
178 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Minor fix to the channel payload; allocate the data area, as it
181 needs to be of specific length.
183 * If the key agreement port is zero then the operating
184 system will define the bound port. Affected files are
185 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
187 * Added new function silc_channel_payload_decrypt into the file
188 lib/silccore/silcchannel.[ch].
190 * Moved the channel message etc, check from silc_packet_decrypt
191 to applications. The library calls now a generic
192 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
193 when the packet is either normal or special. This was done to
194 allow more wide range of checking that was not allowed when
195 the code was in library. Now applications can do virtually any
196 checks to the packet and return to the library the decision how
197 the packet should be processed. Affected files are
198 lib/silccore/silcpacket.[ch].
200 Added silc_server_packet_decrypt_check to the server and
201 silc_client_packet_decrypt_check to the client library.
203 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
204 to send with specified source and destination information.
206 * Channel message delivery between routers was broken after the
207 channel key distribution was fixed earlier. The channel key
208 was used be to distributed to other routers as well which is not
209 allowed by the protocol. Now this is fixed and channel keys
210 really are cell specific and the channel message delivery between
211 routers comply with the protocol specification.
213 * Fixed various commands in server to check also the global list
214 for the channel entry and not just the local list. The affected
215 file silcd/command.c.
217 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Added assert()s to buffer formatting and unformatting routines
220 to assert (if --enable-debug) when error occurs. Affected
221 file: lib/silcutil/silcbuffmt.c.
223 * Changed to auto-reconnect to check whether the remote host is
224 router and register the re-connect timeout if it is. It used
225 to check that whether we are normal server, but router must do
226 auto-reconnect with another router as well. Affected file
229 * Removed the [<key len>] option from CMODE command as the cipher
230 name decides the key length, nowadays. See the defined ciphers
231 from the protocol specification.
233 * Added [<hmac>] option to the CMODE command to define the HMAC
234 for the channel. Added SILC_CMODE_HMAC channel mode.
236 * Added [<hmac>] option for the JOIN command so that user can
237 select which HMAC is used to compute the MACs of the channel
240 * Added Hmac field to the Channel Message Payload. The integrity
241 of plaintext channel messages are now protected by computing
242 MAC of the message and attaching the MAC to the payload. The
243 MAC is encrypted. Now, it is clear that this causes some
244 overhead to the size of the packet but rationale for this is that
245 now the receiver can verify whether the channel message decrypted
246 correctly and also when private keys are set for the channel the
247 receiver can decrypt the packet with several keys and check from
248 the MAC which key decrypted the message correctly.
250 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
251 lib/silccrypt/silccipher.[ch].
253 * Added silc_hash_len to return the digest length into the
254 lib/silcrypt/silchash.[ch].
256 * Rewrote parts of Silc Channel Payload interface in the
257 lib/silccore/silcchannel.[ch]. The encode function now also
258 encrypts the packet and parse function decrypts it.
260 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed a minor formatting bug in the SKE's key material processing.
263 It actually might have processed the keys wrong way resulting
266 * Redefined the mandatory HMAC algorithms and added new algorithms.
267 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
268 and hmac-md5 truncated to 96 bits. The mandatory is now
269 hmac-sha1-96. Rest are optional (including the one that used
270 to be mandatory). Rationale for this is that the truncated HMAC
271 length is sufficient from security point of view and can actually
272 make the attack against the HMAC harder. Also, the truncated
273 HMAC causes less overhead to the packets. See the RFC2104 for
276 * Added new [hmac] configuration section. The SKE used to use
277 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
278 is of course wrong. The official names that must be proposed in
279 the SKE are the ones defined in the protocol specification
280 (hmac-sha1-96 for example). The user can configure any hmac
281 using any hash function configured in the [hash] section. At
282 least, the mandatory must be configured.
284 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
286 * Added HMAC list to the SKE proposal list. It has now both
287 hash algorithm list and HMAC list. This makes the protocol
288 incompatible with previous versions. The SKE now seems to work
289 the way it is supposed to work, for the first time actually.
291 * Defined plain Hash algorithms to the protocol specification.
294 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * Implemented support for key agreement packets into the server.
297 Added functions silc_server_key_agreement and
298 silc_server_send_key_agreement. Other than these functions,
299 server has nothing to do with this packet.
301 * Added support for private message key packets into the server.
302 Added functions silc_server_private_message_key and
303 silc_server_send_private_message_key.
307 * Changed the silc_[client|server]_protocol_ke_set_keys to be
308 called in the protocol's final callback instead in the END
309 protocol state. This makes a little more sense and in the same
310 time in client we can use the same protocol routines for normal
311 key exchange and to key agreement packet handling as well.
313 * Added to both client's and server's KE protocol context the
314 SilcSKEKeyMaterial pointer to save the key material. We will
315 bring the key material to the protocol's final callback by doing
316 this. The final callback must free the key material.
318 * Added SKE's packet_send callback into client's KE protocol
319 context so that the caller can choose what packet sending function
320 is used. This way we can use different packet sending when
321 doing normal SKE when doing key agreement packet handling (in
322 the key agreement packet handling we do not want to encrypt
325 * Implemented the responder side of the key agreement routines
326 in the client. The client can now bind to specified port and
327 accept incoming key negotiation. The key material is passed
328 to the application after the protocol is over.
330 * Implemented the processing of incoming Key Agreement packet
331 in the client. Added function silc_client_key_agreement to
334 * Implemented the intiator side of the key agreement routines
335 in the client. The client can now initiate key agreement with
336 another remote client. The key material is passed to the
337 application after the protocol is over.
339 * Created client_keyagr.c to include all the key agreement
342 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
343 SILC_TASK_CALLBACK except that it is not static.
345 * Created client_notify.c and moved the Notify packet handling
346 from the client.[ch] into that file.
348 * Created client_prvmsg.c and moved all private message and
349 private message key routines from the client.[ch] into that file.
351 * Create client_channel.c and moved all channel message and
352 channel private key routines from the client.[ch] into that file.
354 * Changed silc_client_get_client_by_id_resolve to resolve with
355 WHOIS command instead of IDENTIFY command, in the file
356 lib/silclient/idlist.c.
358 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Implemented the SKE's responder side to the Client library.
362 * When FAILURE is received to the protocol do not trust it
363 blindly. Register a timeout to wait whether the remote closes
364 the connection as it should do it, only after that process the
365 actual failure. This was changed to both client and server.
367 * Added client_internal.h to include some of the structures
368 there instead of client.h in lib/silcclient/.
370 * Added function silc_task_unregister_by_callback to unregister
371 timeouts by the callback function.
373 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Some "Incomplete WHOIS info" errors has been appearing on the
376 log files. Took away the entry->userinfo check from WHOIS
377 reply sending. The entry->userinfo is now " " if client did not
378 provide one. I thought this was fixed earlier but something
379 is wrong still. Let's see if the error still appears.
381 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Fixed a minor bug in the login when the channel key is
384 re-generated in the server. It used to generate the key in
385 wrong order and thus caused problems in the channel traffic.
387 * Fixed a minor bug in channel key distsribution after
388 KICK command. The key was not sent to the router even though
391 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Added silc_ske_process_key_material_data as generic routine
394 to process any key material as the SILC protocol dictates. The
395 function is used by the actual SKE library but can be used by
396 applications as well. This relates to the private message keys
397 and the channel private keys since they must be processed the
398 same way the normal SILC session keys. The protocol dictates
399 this. Affected files: lib/silcske/silcske.[ch].
401 Added also silc_ske_free_key_material to free the
402 SilcSKEKeyMaterial structure.
404 * Defined silc_cipher_set_key function to set the key for
405 cipher without using the object's method function. The affected
406 files: lib/silccrypt/silccipher.[ch].
408 * Implemented silc silc_client_add_private_message_key,
409 silc_client_add_private_message_key_ske,
410 silc_client_del_private_message_key,
411 silc_client_list_private_message_keys and
412 silc_client_free_private_message_keys functions in the
415 Added functions silc_client_send_private_message_key to send
416 the Private Message Key payload and silc_client_private_message_key
417 to handle incoming Private Message Key payload.
419 * Added Cipher field to the Private Message Key payload to set
420 the cipher to be used. If ignored, the default cipher defined
421 in the SILC protocol (aes-256-cbc) is used.
423 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Removed lib/silcclient/ops.h file.
427 Redefined parts of the SILC Client Library API. Created new
428 file silcapi.h that deprecates the ops.h file and defines the
429 published Client Library API. Defined also private message key
430 API and channel private key API into the file.
432 This is the file that the application must include from the
433 SILC Client Library. Other files need not be included by
434 the application anymore.
436 * Added new key_agreement client operation callback and also
437 defined the Key Agreement library API for the application.
439 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
442 is used by clients to request key negotiation between another
443 client in the SILC network. If the negotiation is started it
444 is performed using the SKE protocol. The result of the
445 negotiation, the secret key material, can be used for example
446 as private message key.
448 Implemented the Key Agreement payload into the files
449 lib/silccore/silauth.[ch].
451 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Redefined ciphers for the SILC protocol. Added some new ciphers
454 and defined the key lengths for the algorithms. Changed the
455 code accordingly. The default key length is now 256 bits.
457 * Fixed SKE key distribution function silc_ske_process_key_material
458 when the key length is more than 128 bits. The default key
459 length in SILC is now 256 bits.
461 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
462 to indicate unsupported algorithm.
464 * Renamed rijndael.c to aes.c and all functions as well.
466 * Fixed a long standing channel key setting bug in client library.
467 Weird that it has never surfaced before.
469 * Fixed bug in channel deletion. If the entire channel is removed
470 then it must also delete the references of the channel entry
471 from the client's channel list as the client's channel entry and
472 the channel's client entry share same memory.
474 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Implemented CONNECT and SHUTDOWN commands in the client.
478 * Implemented CLOSE command to the client.
480 * Added the function silc_idlist_find_server_by_name into the
481 files silcd/idlist.[ch].
483 Added the function silc_idlist_find_server_by_conn into the
484 files silcd/idlist.[ch].
486 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * DIE command was renamed to SHUTDOWN. Updated the both code
491 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
492 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
494 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
497 * Added function silc_server_create_connection function to create
498 connection to remote router. My server implementation actually
499 does not allow router to connect to normal server (it expects
500 that normal server always initiates the connection to the router)
501 so the CONNECT command is only good for connecting to another
504 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
507 or some other client was kicked from the channel.
509 Implemented the handling of the notify type to both client
512 Implemented silc_server_send_notify_kicked to send the KICKED
513 notify. It is used to send it to the server's primary router.
515 * Implemented the KICK command into server and client.
517 * Added `query' argument to the silc_idlist_get_client function
518 to indicate whether to query the client from server or not if
521 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
522 to indicate that the client is not channel founder.
526 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Removed the rng context from SilcPacketContext structure and
529 changed that the packet routine uses the Global RNG API.
531 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Added support for quit message that client can "leave" on the
534 channel when it quits the SILC. It is ditributed inside the
535 SILC_NOTIFY_TYPE_SIGNOFF notify type.
537 Added silc_server_free_client_data that will take the
538 signoff message as argument.
540 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
542 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Updated parts of the protocol specification to keep it up
547 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
550 payloads in one packet.
552 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
553 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
554 use now the new List flag.
556 * Also deprecated the following packet types: REPLACE_ID,
557 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
559 * Added list support for Notify packet in server.
561 * Added silc_server_send_notify_channel_change to send the
562 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
563 the silc_server_send_replace_id.
565 * Added silc_server_send_notify_nick_change to send the
566 NICK_CHANGE notify type. Deprecates the function
567 silc_server_send_replace_id.
569 * Added silc_server_send_notify_join to send the JOIN notify type.
570 Deprecates the function silc_server_send_new_channel_user.
572 * Added silc_server_send_notify_leave to send LEAVE notify type.
573 Deprecates the function silc_server_send_remove_channel_user.
575 * Added silc_server_send_notify_cmode and
576 silc_server_send_notify_cumode to send CMODE and CUMODE notify
577 types. Deprecates the silc_server_send_set_mode function.
579 * Added SERVER_SIGNOFF notify type to indicate that server has
580 quit. This means that all clients on the channel from that
581 server will drop. This can be also used when netsplit happens.
583 Deprecated REMOVE_ID packet type since it is not needed anymore
586 Added silc_server_send_notify_server_signoff to send the
587 SERVER_SIGNOFF notify type. Deprecates the function
588 silc_server_send_remove_id.
590 Added also silc_server_send_notify_signoff to send the
593 * Employed the PKCS #1. It is the mandatory way to do RSA in the
594 SILC protocol from this day on. Changed the protocol
595 specification as well.
597 * Added silc_server_send_notify_topic_set to send TOPIC_SET
598 notify type. It is used between routers to notify about
599 topic changes on a channel.
601 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
604 * Partly updated the protocol specification to comply with the
605 changes now made. It is still though a bit outdated.
607 * The JOIN notify type now takes one extra argument <Channel ID>.
608 The packet used to be destined to the channel but now the
609 JOIN type may be sent as list thus it is impossible to
610 destine it to any specific channel. By adding this argument
611 it is again possible.
613 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Added CREDITS file. The CHANGES and CREDITS file will appear
616 in the distribution as well.
618 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
621 types in the server's silcd/packet_receive.c.
623 * Implemented CMODE and CUMODE to work in router environment.
625 * Fixed minor encoding and decoding buglet from the
626 lib/silccore/silcmode.c.
628 * Fixed buffer overflow from lib/silcclient/command.c in USERS
631 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
633 * Changed all SilcConfigServer* and silc_config_server* to
634 SilcServerConfig* and silc_server_config*, respectively.
637 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Associated the ID (client or server ID) to the Authentication
640 Payload to avoid any possibility of forging. Updated the
641 protocol specification and the code accordingly.
643 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * The RSA key length is now save to the RsaKey context in the
646 key generation process in lib/silccrypt/rsa.c. The key length
647 is now used to figure out the maximum size of the block allowed
648 to be encrypted/signed.
650 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
651 is equivalent to the silc_mp_mp2bin but does not allocate any
654 * Changed silc_mp_mp2bin API to take length argument. If it is
655 non-zero then the buffer is allocated that large. If zero, then
656 the size is approximated using silc_mp_sizeinbase, which however
659 * Created Global RNG API which is global RNG that application can
660 initialize. After initializing, any routine anywhere in the
661 code (including library) can use RNG without allocating a new
662 RNG object. This was done to allow this sort of use of the
663 RNG in code that has no chance to allocate RNG object. All
664 applications currently allocate this and many routines in the
665 library use this. Affected file lib/silccrypt/silcrng.[ch].
667 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
668 it to use the Global RNG API.
670 * Defined Authentication Payload into protocol specification that
671 is used during SILC session to authenticate entities. It is
672 used for example by client to authenticate itself to the server
673 to obtain server operator privileges.
675 Implemented this payload into the lib/silccore/silcauth.[ch].
676 Implemented also routines for public key based authentication
677 as the new protocol specification dictates.
679 Moved definitions of different authentication methods from
680 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
682 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
683 silc_pkcs_verify and silc_pkcs_sign_with_hash and
684 silc_pkcs_verify_with_hash functions into the file
685 lib/silccrypt/silcpkcs.[ch].
687 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * The client entry's userinfo pointer must be always valid.
690 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
691 will fail since it requires the userinfo. Now, the userinfo
692 is allocated as "" if actual userinfo does not exist. Actually,
693 it must exist and it is totally Ok to drop client connections
694 that does not announce the userinfo. However, we will make
695 this workaround for now.
697 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
698 to return the remote port by socket.
700 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
703 SILC_SERVER_PENDING_EXEC and added an new macro
704 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
705 data or when error occurs while processing the pending command.
707 Added new argument `destructor' into silc_server_command_pending
708 and to the SilcServerCommandPending object. This destructor is
709 now called after calling the pending callback or if error occurs
710 immediately. If error occurs the actual pending callback won't
711 be called at all - only the destructor. The destructor may be
712 NULL if destructor is not needed.
714 All this applies for client library code as well. Similar
715 changes were made there as well for the pending commands.
717 In the client, the application must now allocate the
718 SilcClientCommandContext with the silc_client_command_alloc
721 * Added reference counter to the SilcServerCommandContext. Added
722 function silc_server_command_alloc and silc_server_command_dup
725 Same type of functions added to the client library for the same
728 * Removed the cmd_ident from IDListData away since it is now
729 global for all connections. It is the command identifier used
730 in command sending and with pending commands. The affected file
733 * Added reference counter to the SilcSocketConnection objecet to
734 indicate the usage count of the object. The object won't be
735 freed untill the reference counter hits zero. Currently only
736 server uses this, and client ignores it. The client must be
737 set to use this too later. The affected files are
738 lib/silccore/silcsockconn.[ch]. Added also the function
739 silc_socket_dup to increase the reference counter.
741 This was mainly added because it is possible that the socket
742 is removed underneath of pending command or other async
743 operation. Now it won't be free'd and proper DISCONNECTING
744 flags, etc. can be set to avoid sending data to connection that
745 is not valid anymore.
747 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
748 the connection. After that it sets SILC_SET_DISCONNECTED.
749 It is, however, possible that the socket data is not still freed.
750 The silc_server_packet_process now checks that data is not
751 read or written to connection that is DISCONNECTED. The socket
752 get's freed when the reference counter hits zero.
754 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Changed the client operation API: channel_message operation's
757 `sender' is now the client entry of the sender, not the nickname
758 and the `channel' is the channel entry, not the channel name.
760 In the private_message operation the `sender' is now also the
761 client entry of the sender not the nickname.
763 Affected file is lib/silcclient/ops.h and all applications
764 using the client operations.
766 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
768 * Moved the calling of ops->connect() from connect_to_server_final
769 into receive_new_id functin since that is the point when the
770 client is actually allowed to send traffic to network. The
771 affected file is lib/silcclient/client.c.
773 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
776 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
777 (if needs broadcasting) instead of broadcasting the packets one
778 by one which would make a burst in the network traffic.
780 * Added `broadcast' argument to the functions in silcd/server.[ch]
781 silc_server_create_new_channel[_with_id] to indicate whether
782 to send New Channel packet to primary router.
784 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
786 * Added new function into the silcd/server.[ch] files:
787 silc_server_create_new_channel_with_id to create new channel with
788 already existing Channel ID.
790 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
791 lib/silccore/silcpacket.h. This packet is used t send list of
792 Set Mode payloads inside one packet. Server uses this to set
793 the modes for the channels and clients on those channels, that it
794 announced to the router when it connected to it. The protocol
795 specification has been updated accordingly.
797 * The silc_server_new_channel did not handle the packet coming
798 from normal server as it normally does not send that. However,
799 when it announces its channels it does send it. Implemented
800 the support for that.
802 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
803 into the file lib/silccore/id.h.
805 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Fixed memory leaks in the functions silc_idlist_del_client,
808 silc_idlist_del_channel and silc_idlist_del_server in the file
809 silcd/idlist.c. All of those leaked like a sieve.
811 * Fixed some small memory leaks in the client's function
812 silc_client_notify_by_server.
814 * Added functions into silcd/server.c: silc_server_announce_clients,
815 silc_server_announce_channels and silc_server_announce_server.
816 These functions are used by normal and router server to announce
817 to its primary router about clients, channels and servers (when
818 router) that we own. This is done after we've connected to the
821 These functions effectively implements the following packet types:
822 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
823 and SILC_PACKET_NEW_ID_LIST.
825 * Added new functions into the silcd/packet_receive.[ch]:
826 silc_server_new_id_list, silc_server_new_channel_list and
827 silc_server_new_channel_user_list to handle the incoming
828 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
830 * Added support of changing Channel ID in the function
831 silc_server_replace_id. If the server that announces a channel
832 to the router already exists in the router (with same name but
833 with different Channel ID), router is responsible to send
834 Replace ID packet to the server and force the server to change
835 the Channel ID to the one router has.
837 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
838 client that the Channel ID has been changed by the router. The
839 normal server sends this to the client. Client must start using
840 the new Channel ID as the channel's ID.
842 Implemented handling of this new type into lib/silcclient/client.c
843 into the function silc_client_notify_by_server.
845 * Added new function silc_idlist_replace_channel_id into the files
846 silcd/idlist.[ch] to replace the Channel ID.
848 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Call silc_server_command_identify_check always when processing
851 the IDENTIFY command in silcd/command.c
853 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
856 send keepalive packets. The packet can be sent by clients,
859 Added function silc_socket_set_heartbeat into the file
860 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
861 If not set, the heartbeat is not performed. The actual
862 heartbeat is implemented in the low level socket connection
863 library. However, application is responsible of actually
866 Added silc_server_send_heartbeat to send the actual heartbeat
867 packet into silcd/packet_send.[ch]. Server now performs
868 keepalive with all connections.
870 * Added silc_task_get_first function into lib/silcutil/silctask.c
871 to return the timeout task with shortest timeout. There was a bug
872 in task unregistration that caused problems. TODO has been
873 updated to include that task system must be rewritten.
875 * The client library will now resolve the client information when
876 receiving JOIN notify from server for client that we know but
877 have incomplete information.
879 * Rewrote parts of silc_server_remove_from_channels and
880 silc_server_remove_from_one_channel as they did not remove the
881 channel in some circumstances even though they should've.
883 * Encryption problem encountered in server:
885 The LEAVE command used to send the Channel Key packet to the
886 router immediately after generating it. However, the code
887 had earlier sent Remove Channel user packet but not immediately,
888 ie. it was put to queue. The order of packets in the router
889 was that Channel Key packet was first and Remove Channel User
890 packet was second, even though they were encrypted in the
891 reverse order. For this reason, MAC check failed. Now, this
892 is fixed by not sending the Channel Key packet immediately but
893 putting it to queue. However, this is more fundamental problem:
894 packets that are in queue should actually not be encrypted
895 because packets that are sent immediately gets encrypted
896 actually with wrong IV (and thus MAC check fails). So, packets
897 that are in queue should be encrypted when they are sent to
898 the wire and not when they put to the queue.
900 However, the problem is that the current system has not been
901 designed to work that way. Instead, the packet is encrypted
902 as soon as possible and left to the queue. The queue is then
903 just purged into wire. There won't be any fixes for this
904 any time soon. So, the current semantic for packet sending
907 o If you send packet to remote host and do not force the send
908 (the packet will be in queue) then all subsequent packets to the
909 same remote host must also be put to the queue. Only after the
910 queue has been purged is it safe again to force the packet
913 o If you send all packets immediately then it safe to send
914 any of subsequent packets through the queue, however, after
915 the first packet is put to queue then any subsequent packets
916 must also be put to the queue.
918 Follow these rules and everything works fine.
920 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added new function silc_server_remove_clients_by_server to
923 remove all client entries from ID list when the server connection
924 is lost. In this case it is also important to invalidate all
925 client entires as they hold the invalid server entry. This
926 fixes fatal bug when server has lost connection and will reconnect
929 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Made some sanity checks to silc_server_daemonise like to check
932 whether the requested user and group actually exists.
934 * Added sanity check to SKE's silc_ske_responder_finish to check
935 that the public and private key actually is valid.
937 * Invalidate the client's nickname when receiving Replace ID
938 packet and the Client ID is being replaced. This means that the
939 server will query the nickname if someone needs it (client)
942 * Sort the ID Cache in client library when the ID Cache data
943 has changed (needs sorting).
945 * Do not allow for SILC client to create several connections to
946 several servers. The client does not support windows right now
947 and generating multiple connections causes weird behaviour.
949 Irssi-silc client does support windows and can handle several
950 connections without problems, see: www.irssi.org and SILC plugin.
952 * Fixed some places where client was added to the IDList. The
953 rule of thumb is following (in order to get everything right):
954 If the client is directly connected local client then the
955 `connection' argument must be set and `router' argument must be
956 NULL to silc_idlist_add_client function. If the client is not
957 directly connected client then the `router' argument must
958 bet set and the `connection' argument must be NULL to the
959 silc_idlist_add_client function.
961 * The funtion silc_server_packet_send_local_channel actually did
962 not check whether the client was locally connected or not. It
963 does that now. Fixed a bug related to LEAVE command.
965 * Fixed Remove Channel User payload parsing bug in server's
966 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
968 * The server's silc_server_save_channel_key now checks also the
969 global ID list for the channel as it might not be in the local
970 list. Fixed a bug related to LEAVE command.
972 * Is this the end of the [<unknown>] buglet that has been lurking
973 around for a long time? A little for loop fix in server's
974 silc_server_command_whois_parse that is used by both IDENTIFY
975 and WHOIS command. At least, this was a clear bug and a cause
976 of one type of [<unknown>] buglet.
978 * WHOIS and IDENTIFY commands call the function
979 silc_server_command_[whois/identify]_check function even if
980 we are not router server.
982 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added --with-gmp configuration option. If set the GMP
985 is always compiled in the SILC source tree. If not set then
986 it is checked whether the system has the GMP3 installed. If
987 it has then the GMP won't be compiled (the system's headers
988 and library is used), if it doesn't have it then the GMP is
989 compiled in the SILC source tree.
991 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Changed RSA private exponent generation to what PKCS #1
994 suggests. We try to find the smallest possible d by doing
995 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
996 not security fix but optimization.
998 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1000 * Added new config entry [Identity] to fork the server and run
1001 it as specific user and group. A patch from Bostik.
1003 * Imported Dotconf configuration library into lib/dotconf.
1004 This will be used to create the SILC configuration files later.
1005 It will appear in the distsribution after this commit.
1007 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * A big code auditing weekend happening. Auditing code for
1010 obvious mistakes, bugs and errors. Also, removing any code
1013 Removed files for being obsolete:
1015 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1016 inline in the file lib/silcutil/silcbuffer.h)
1018 o lib/silcutil/silcbufutil.c (the header has inline versions)
1020 Changed code to fix possible error conditions:
1022 o The buffer formatting routines now check that the destination
1023 buffer really has enough space to add the data. This applies for
1024 both buffer formatting and unformatting
1025 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1026 unformatting was changed to accomodate following rules:
1027 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1028 sent to the function while XXX_*STRING will not allocate or copy
1029 the data into the buffer. Instead it sets the pointer from the
1030 buffer into the pointer sent as argument (XXX_*STRING used to
1031 require that the pointer must be allocated already). This change
1032 makes this whole thing a bit more consistent and more optimized
1033 (note that the data returned in the unformatting with XXX_*STRING
1034 must not be freed now). The routines return now -1 on error.
1036 o Tried to find all code that use buffer_format and buffer_unformat
1037 and added return value checking to prevent formatting and
1038 especially unformatting errors and possible subsequent fatal
1041 o Changed ske->x and ske->KEY to mallocated pointers in
1042 lib/silcske/silcske.h. Fixed possible data and memory leak.
1044 o Added return value checking to all *_parse* functions. Fixed
1045 many memory leaks as well.
1047 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1048 so that buffer overflows would not happen. All code now also
1049 checks the return value as it can fail.
1051 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Added reconnection support to server if the normal server looses
1054 its connection to the router (for example if router is rebooted).
1055 The server performs normal reconnection strategy implemented
1056 to the server. Affected file silcd/server.c.
1058 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Added new packet type SILC_PACKET_SET_MODE that is used to
1061 distribute the information about changed modes (for clients,
1062 channels and clients channel modes) to all routers in the
1063 network. Updated the protocol specification accordingly.
1065 Added functions into silcd/packet_send.c and
1066 silcd/packet_receive.c: silc_server_send_set_mode,
1067 silc_server_set_mode.
1069 Added new files silcmode.[ch] into lib/silccore that implements
1070 the encoding and decoding of Set Mode Payload. Added new type
1071 SilcSetModePayload. Moved the definitions of different modes
1072 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1074 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Oops, a little mistake in server's connection authentication
1077 protocol. The protocol is not ended with FAILURE but with
1078 SUCCESS if the authentication is Ok. :) Affected file is
1081 * Implemented NICK_CHANGE notify handling in server in the file
1082 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1083 the local clients on the channel. After the changing nickname
1084 in router environment snhould work and the [<unknown>] nickname
1085 should appear no more.
1087 The silc_server_replace_id function that receives the Replace ID
1088 payload now sends the NICK_CHANGE notify type also in the file
1089 silcd/packet_receive.c
1091 * Changed WHOIS and IDENTIFY command to support the maximum amount
1092 of arguments defined in protocol specs (3328 arguments). This
1093 fixed a bug that caused problems when there were more than three
1096 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Added extra parameter, command identifier, to the
1099 silc_client_send_command so that explicit command identifier
1102 Changed that ID list routines uses specific command identifier
1103 when sending WHOIS/IDENTIFY requests to the server so that they
1104 can be identified when the reply comes back.
1106 Affected files lib/silcclient/command.[ch],
1107 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1109 * Added `sender' argument to silc_server_packet_send_to_channel
1110 to indicaet the sender who originally sent the packet to us
1111 that we are now re-sending. Ignored if NULL. Affected file
1112 silcd/packet_send.[ch].
1114 * Added some server statistics support in silcd/server_internal.h
1115 SilcServerStatistics structure and around the server code. Also
1116 send some nice statistics information when client is connecting
1119 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Fixed channel ID decoding in server's JOIN command reply in
1122 silcd/command_reply.c
1124 * Fixed braodcasting of replace ID payload to not to send it if
1125 we are standalone server in silcd/packet_receive.c.
1127 * Fixed all channel message sending routines to not to send
1128 packets to clients that has router set, since they are routed
1129 separately in the same function earlier. Affects file
1130 silcd/packet_send.c and all channel packet sending functions.
1132 * In USERS reply, res_argv[i] are not allocated, the table
1133 is allocated. Thus changed that free the table, not its
1136 * In server's whois_check and identify_check if the client is
1137 locally connected do not send any WHOIS commands - they are not
1140 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Fixed some minor bugs in client when sending WHOIS command. The
1143 arguments was in wrong order.
1145 * Removed statis function add_to_channel from server in
1146 silcd/command.c that was previously used with the joining but
1149 * Tested USERS command in router environment successfully with two
1150 routers, two servers and two clients.
1152 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Reorganized the USERS command and command reply in client library
1155 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1156 When the command is given by user we register a pending command
1157 callback that will reprocess the command after the reply has been
1158 received from the server. When reprocessing the packet we then
1159 display the information. Thus, the USERS information is displayed
1160 now in the command callback instead of in the command reply
1161 callback. The processing of the command is same as previously
1162 when server has sent the command reply in the JOINing process.
1164 * Added to USERS command in silcd/command_reply.c to join the client,
1165 we didn't use to know about, to the channel after we've created
1166 a client entry for it. Also, for clienet we did know already still
1167 check whether it is on the channel or not and add it if not.
1169 * Removed silc_server_command_join_notify as the function and its
1172 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Changed the client's pending command handling to the same as the
1175 server's pending command handling. It is also now possible to
1176 execute command reply functions from other command reply
1177 function as the function callbacks for commands and command
1178 replies are one and same. The pending commands are not static
1179 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1180 in client connection context. Thus, pending commands are server
1181 connection specific as it is convenient.
1183 Changed the function silc_client_command_pending and
1184 silc_client_command_pending_del and added new function
1185 silc_client_command_pending_check. Removed the
1186 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1189 * Added cmd_ident, current command identifier, to the client
1190 connection context in lib/silcclient/client.h to keep track on
1191 command identifiers used in command sending. Client's command reply
1192 function handling now supports the mandatory command identifiers.
1194 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1195 funtions in client to fully support pending command callbacks.
1197 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1198 as one of the arguments to the application in the command reply
1201 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1202 before first releasing SILC but came back. Now it is removed again
1203 and should come back nomore. The FORWARDED flag was used only
1204 by the JOINing procedure by forwarding the command packet to router.
1205 Now, the JOINing procedure has been changed to more generic (due
1206 to various router environment issues) and FORWARDED is not needed
1207 anymore for anything. The protocol specification is yet to be
1210 Now, removed silc_server_packet_forward from server and the flag
1211 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1213 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Renamed NAMES command to USERS command. The NAMES was named that
1216 due to historical reasons. Now it is renamed. Also, rewrote
1217 parts of the USERS command. The nickname list is not sent anymore
1218 by the server. Only Client ID and mode lists are sent in the USERS
1219 command. Changed this also to the protocol specification.
1221 The client now resolves the names and stuff after it receives
1222 the USERS list from the server when joining to the channel.
1224 * WHOIS and IDENTIFY commands has been changed to support multiple
1225 Client ID's per command. One can now search for multiple users
1226 in the network by sending only one WHOIS or IDENTIFY command.
1227 Changed the code and the protocol specifications.
1229 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1230 uses silc_server_command_whois_parse to parse the request. */
1232 * If normal server, do not parse the WHOIS and IDENTIFY requests
1233 before sending it to the router. Saves some time.
1235 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Fixed JOIN command on client library. Wrong number of arguments
1238 used to crash the client.
1240 * Added silc_server_channel_has_global function to check whether
1241 channel has global users or not.
1243 * Added silc_server_channel_has_local function to check whether channel
1244 has locally connected clients on the channel.
1246 * The silc_server_remove_from_one_channel now checks whether the
1247 channel has global users or not after given client was removed from
1248 the channel. It also checks whether the channel has local clients
1249 on the channel anymore. If it does not have then the channel entry
1250 is removed as it is not needed anymore.
1252 * The silc_server_notify now checks on JOIN notify whether the joining
1253 client is one of locally connected or global. If it is global then
1254 the channel has now global users on the channel and that is marked
1255 to the channel entry. Also, it now saves the global client to
1256 global list who is joining and JOINs it to the channel. This is
1257 for normal server, that is.
1259 Changed silc_server_send_notify_on_channel,
1260 silc_server_packet_relay_to_channel and
1261 silc_server_packet_send_to_channel check if we are normal server
1262 and client has router set (ie. global client) do not send the
1263 message to that client, as it is already routed to our router.
1265 * Implemented LEAVE notify type handling in silc_server_notify
1268 * Tested LEAVE command in router environment successfully. Tested
1269 with two routers, two servers and two clients.
1273 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1275 * Implemented SIGNOFF notify type handling in silc_server_notify
1278 * silc_server_remove_id now removes the client entry from all channels
1279 it has joined and thusly sends SIGNOFF notify type.
1281 * Rewrote the NAMES list generation in server by removing two excess
1282 loops. The lists are created now inside one loop.
1284 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * silc_server_remove_channel_user checks now also global list
1287 for channel and client.
1289 * silc_server_new_channel_user checks now both local and global
1290 list for channel and client. Fixed a bug in client id decoding.
1291 Used to decode wrong buffer.
1293 * silc_server_channel_message checks now both local and global
1294 list for channel entry.
1296 * Tested channel joining (hence JOIN) in router environment
1297 successfully. Tested with two routers, two servers and two
1300 * Tested channel message sending in router environment successfully.
1302 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Added silc_server_save_channel_key into server.[ch] to save the
1305 received channel key in Channel Key payload processing. It is
1306 also used in JOIN command reply handling.
1308 Equivalent function silc_client_save_channel_key added into
1309 client.[ch] into client library.
1311 * Changed JOIN command reply to send information whether the channel
1312 was created or not (is existing already) and the channel key
1313 payload. Changed protocol specs accordingly.
1315 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1316 the request was sent by ID and not by nickname. Crashed on
1319 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1322 now correctly save the received data.
1324 * silc_server_free_sock_user_data now notifies routers in the
1325 network about entities leaving the network.
1327 At the same time implemented functions silc_server_remove_id
1328 and silc_server_send_remove_id to receive and send REMOVE_ID
1329 packets. The packet is used to notify routers in the network
1330 about leaving entities. The ID removed will become invalid in
1333 * Added function silc_idlist_del_server into server. Removes and
1334 free's server entry from ID list.
1336 * silc_server_private_message function now checks, if we are router,
1337 that the destination ID really is valid ID, naturally.
1339 * In router when NEW_ID packet is received (for new client) the
1340 hash of the Client ID is saved in the ID Cache but the
1341 client->nickname is set to NULL, instead of putting the hash
1344 IDENTIFY command now also checks that client->nickname must be
1345 valid. If it is not if will request the data from the server who
1346 owns the client. Added new function
1347 silc_server_command_identify_check.
1349 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1350 to set the command to already allocated Command Payload.
1352 * Tested private message sending in router environment with two
1353 routers, two servers and two clients. Fixed minor bugs and now
1356 * Fixed segfault from client's NAMES command. Used to crash if
1359 * Forwarded packets must not be routed even if it is not destined
1360 to the receiver. Changed server code comply with this.
1362 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Added `require_reverse_mapping' boolean value to ServerParams
1365 structure. If TRUE (not default) the server will require that
1366 the connecting host has fully qualified domain name.
1368 If the reverse mapping is not required and hostname could not be
1369 found the IP address is used as hostname.
1371 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Implemented version string checking to both client and server.
1374 The check is incomplete currently due to the abnormal version
1375 strings used in development version of SILC.
1377 * Changed all command functions in server to use the new
1380 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Changed char *data to unsigned char *data in ID Cache system to
1383 support binary data as ID Cache data. Changed code to support
1384 binary data in lib/silccore/idcache.c.
1386 * Renamed silc_server_packet_relay_command_reply to
1387 silc_server_command_reply as it is normal packet receiving
1388 function. Rewrote the function to accept command replys for
1389 servers and not only for clients.
1391 * Mark remote router always as registered server if we are connecting
1392 to it. Otherwise, commands sent by the router to us are ignored.
1394 * All ID List find routines now returns the ID Cache Entry pointer
1395 as well if requested.
1397 * WHOIS command works now in router environment, tested with two
1398 routers, two servers and two clients.
1400 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1401 in router environment (as it is almost equivalent to WHOIS) but
1402 hasn't been tested thoroughly. Added new functions:
1404 silc_server_command_identify_parse
1405 silc_server_command_identify_send_reply
1406 silc_server_command_identify_from_client
1407 silc_server_command_identify_from_server
1409 * Disabled route cache adding because adding two different ID's with
1410 same IP replaces the old cache entry thus giving wrong route.
1411 The entry->router->connection is always the fastest route anyway
1412 so route cache may not be needed. Of course, new routes maybe
1413 established after receiving the ID when the entry->router->connection
1414 might not be anymore the most optimal.
1416 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Add route cache for received ID for fast routing.
1420 * Added silc_server_packet_route to route received packet on router
1421 that is not destined to us.
1423 * Renamed silc_server_get_route to silc_server_route_get.
1425 * Added id_string and id_string_len fields into SilcServer to
1426 include encoded ServerID for fast comparing without excess
1427 encoding of the ID's.
1429 * Cleaned up WHOIS command on server side. Added following static
1432 silc_server_command_whois_parse
1433 silc_server_command_whois_check
1434 silc_server_command_whois_send_reply
1435 silc_server_command_whois_from_client
1436 silc_server_command_whois_from_server
1438 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1439 arguments in command replies. All command functions should be
1440 updated to use this macro.
1442 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Minor typo fixes on command reply handling on server.
1446 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Added silc_server_command_add_to_channel internal routine to add
1449 the client to the channel after router has created the channel and
1450 sent command reply to the server.
1452 * Added generic silc_server_send_command to send any command from
1455 * Use static buffer with ID rendering instead of duplicating data.
1457 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Fixed a channel user mode bug when joining to a channel server gave
1460 everybody channel founder rights, oops.
1462 * We mark ourselves as the router of the incoming server connection
1463 if we are router ourselves. This way we can check in some packet
1464 sending functions whether it is locally connected server. For
1465 incoming router connections we put NULL.
1467 * For router sending packets locally means now always sending the
1468 packet cell wide; to local clients and local servers. For normal
1469 server sending packet locally means sending it to only local
1472 * Fixed the JOIN command to really work in router environment. If the
1473 channel is created it is always created by the router. Router is
1474 also responsible of making the initial joining to the channel,
1475 sending JOIN notify to the sending server and distributing
1476 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1477 does not exist server doesn't do anything else but forward the
1478 command to the router which performs everything.
1480 * Added silc_server_send_channel_key function to send the Channel Key
1483 * Added silc_server_create_channel_key to create new channel key. The
1484 channel key is now re-generated everytime someone joins or leaves
1485 a channel, as protocol dictates. Note: channel->key_len is the
1488 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1491 packet_receive.[ch] to separate packet sending and receiving
1492 routines. The server.[ch] now includes everything else including
1493 actual packet processing (writing and reading data) and other
1496 Renamed silc_server_private_message_send_internal to
1497 silc_server_send_private_message. The routine is still though
1498 used only to relay private messages as server does not send
1499 private messages itself.
1501 Renamed silc_server_new_channel to silc_server_create_new_channel
1502 and added new function sicl_server_new_channel that handles the
1503 incoming New Channel packet. Added also new sending function
1504 silc_server_send_new_channel to send New Channel Payload.
1506 * Added new function silc_server_notify to process incoming notify
1507 packet to the server/router. Server may then relay the notify
1508 to clients if needed.
1510 * Added new function silc_server_new_channel_user to process incoming
1511 New Channel User packet. Router will redistribute the packet and
1512 send JOIN notify to its local clients and locally connected servers
1513 if needed. Normal server will send JOIN notify to its local client
1514 on same channel when received this packet. Added also corresponding
1515 sending function silc_server_send_new_channel_user to sent the
1518 * Added boolean route argument to send_notif_to_channel and
1519 packet_send_to_channel functions to attempt to route the packet
1520 if it is TRUE and send only locally if it is FALSE.
1522 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1524 * silc_server_replace_id now broadcasts the received replace ID
1525 packet if it is not broadcast packet already. The router must
1526 broadcast to inform other routers about changed ID.
1528 * Added backpointer to server's router into SilcServer context in
1529 silcd/server_internal.h.
1531 * Fixed silc_server_packet_broadcast to send correct broadcast
1534 * The channel key is now distributed to the local client as soon
1535 as it is received from the router (in router environment) so that
1536 no other packet may be sent for the channel until client has
1539 * silc_server_remove_channel_user now broadcasts the received
1540 Remove Channel User packet if it is not broadcast packet already.
1541 The router must broadcast to inform other routers about removed
1544 * Added users field into SilcPacketContext that is a reference count
1545 of the context. One can increase the reference count by calling
1546 silc_packet_context_dup which is now changed to just increase the
1547 reference count instead of duplicating the data. The reference
1548 count is decresed by calling silc_packet_context_free that will
1549 free the data after the reference count hits zero.
1551 For now on the packet context and everything allocated into it
1552 (including the raw packet from network) must be freed by calling
1553 the new silc_packet_context_free function. Added also new function
1554 silc_packet_context_alloc that must be used now to allocate the
1555 context. This also means that if a routine is asynchronous from
1556 silc_[client/server]_packet_parse_type the packet context must
1557 be duplicated by calling silc_packet_context_dup. Otherwise it
1558 gets free'd after silc_[client/server]_packet_parse_type returns.
1559 Also, one must remember that if packet is duplicated then its
1560 reference count must be decresed by calling the free function as
1561 many times as it was duplicated.
1563 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1564 from both client and server.
1566 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Made joining to a channel working in router environment.
1570 * Cleaned up JOIN command on server side and create function
1571 silc_server_command_join_channel internal routine to make the
1574 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Changed silc_command_pending list to SilcDList. Also, added
1577 `ident' field to SilcServerCommandPending structure to identify
1578 the reply and to call correct callback.
1580 Added silc_server_command_pending_check function to replace the
1581 corresnponding macro. The silc_command_pending list is not
1584 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1585 to set identifier to previously allocated Command Payload. It
1586 is used to set identifier for command when resending Command
1589 * Added silc_command_payload_encode_payload to encode Command
1590 Payload buffer from SilcCommandPayload structure.
1592 * Added silc_argument_payload_encode_payload to encode Argument
1593 payload buffer from SilcArgumentPayload structure.
1595 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * Changed WHOIS command to support router connection on server side.
1598 The whois request is always sent to router unless the server is
1599 standalone server. After server has received the reply from the
1600 router will it send the reply to the client.
1602 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1603 broadcast received broadcast packet. The function is used only
1604 by router. The broadcast packet is always sent to the router's
1607 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1608 render given ID to printable string, for log files for example.
1610 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Made basic router to router connections working. At least they
1613 can now connect to each other but nothing really works the way
1614 they are supposed - yet.
1616 * Added new initiator token to RouterConnection configuration
1617 file in silcd/serverconfig.[ch]. It is used to tell whether we
1618 are the initiator to the remote router or whether we'll expect
1619 the other end to connect.
1621 * Moved registering of listener task to silc_server_init, hence
1622 the server starts listenning as soon as it is run, even if it
1623 does not have connections to other routers. Let's see how well
1626 * Changed default connection retry timeouts for more suitable in
1629 * Removed cipher and such arguments from silc_idlist_add_client
1630 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1631 Added new function silc_idlist_add_data to add the keys and stuff
1634 * Added SilcIDListData structure and added it to SilcClientEntry
1635 and SilcServerEntry as their first field in the structure. This
1636 way we can explicitly cast the ID entries to the SilcIDListData
1637 structure and get common data for the entries. In past, we had
1638 to first check what type of connection it is and then cast it to
1639 correct ID entry type. Now, we can directly cast the opaque
1640 pointer to the SilcIDListData (no matter what ID entry it actually
1641 is) and get the data needed.
1643 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1646 in some circumstances even if threre were timeout tasks, though not
1647 IO tasks, but tasks anyway. Now fixed.
1649 * Defined SilcServerConnection structure to hold connection specific
1650 stuff about directly connected servers and routers. The definition
1651 is currently in silcd/server_internal.h. I thought about having
1652 a bit more important role fro this struct but for now it is used
1653 only when connecting to other server (or router actually).
1655 * Added connecting retry support in server when connecting to
1656 router(s). The retry feature implement exponential backoff
1657 algorithm. Also, added SilcServerParams structure to hold default
1658 parameters for server. For now, it include these retry settings
1659 and are hard coded. After server is moded to be as Silc Server
1660 Library this structure will be more important.
1662 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Changed client librarys channel->clients table to SilcList and
1665 changed code accordingly.
1667 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Changed client's channel table to SilcList and changed code
1670 accordingly. Also changed SilcChannelClientEntry to include back-
1671 pointer to the channel so that client entry can use that structure
1672 as list as well and we have fast cross-reference to the channel.
1673 This change dramatically decreased the complexity of channel
1674 handling with client entry and vice versa (removed one extra
1675 loop when searching for channel entry from many functions).
1677 * Changed server->sim from table to SilcDList and changed code
1680 * NAMES command can now be used from user interface. It will show
1681 the user list on the channel, neatly.
1683 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1684 Code now saves realname of the user if it becomes available.
1686 * Renamed configure.in to configure.in.pre and made ./prepare
1687 script to automatically add correct version string to
1688 configure.in which it creates from configure.in.pre.
1690 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * NAMES command reply now shows users mode with the nickname when
1695 * Moved silc_client_ch[u]mode[_char] functions from
1696 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1697 place sucks, they are utility functions and should be in some
1700 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1702 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1705 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Added TRQ (efficient deque and list library) into lib/trq. This is
1710 a very good list library that is currently used in the SILC. Defined
1711 SilcList API over the library because I didn't like the API very
1712 much. See lib/trq/silclist.h for the API and examples of how to
1713 use the API. Fixed various places in the code to use the new
1714 SilcList API. The SilcList is meant for lists that has a structure
1715 already defined as a list. It is not suitable to add just some
1716 context to the list (in TRQ, the context is the list actually).
1718 So, I defined SilcDList that can be used for the purpose where
1719 predefined list structure does not exit. This can be used as
1720 such list. Now some context just can be added to the SilcDList.
1721 Currently this list is not used in the SILC just yet, though there
1722 are a lot places where this can replace dynamically allocated
1723 tables and I will fix these places, later, to use SilcDList.
1724 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1725 and use TRQ internally).
1727 Also fixed some annoying warning messages that the original TRQ
1728 code generated. Also minor changes to TRQ's Makefile.in.
1730 * Added support for querying by Client ID to both WHOIS and
1731 IDENTIFY commands into server, as required by the protocol.
1733 * Removed method function pointers from SilcBuffer structure. They
1734 weren't used to anything and just increased the context size for
1735 no good reason. This change also made silc_buffer_alloc and
1736 silc_buffer_free functions inline functions.
1738 * Disabled command flooding detection support until it's fixed so
1739 that it accepts commands in but does not execute them more than once
1742 * Added silc_net_localhost(), to return local hostname, into
1743 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1744 that must be initialized before calling silc_client_init.
1746 * Added new function: silc_server_send_notify_on_channels to send
1747 notify messages to all channels client has joined. It is assured
1748 that the message is sent only once per client.
1750 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1751 lib/silcutil/silcutil.[ch] as silc_format function. The new
1752 function is generic and is used by server as well, not only by
1753 the logging routines.
1755 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1756 the provided version string was not acceptable. Added new function:
1757 silc_ske_check_version into lib/silcske/silcske.h. The function
1758 must be implemented by the application (client or server) and it
1759 does not reside in the SKE library. The function checks the version
1760 string remote end sent.
1762 * Added back pointers (to opaque context and to SilcSocketConnection)
1763 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1765 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1766 duplicate packet context structure.
1768 * Changed `notify' client operation to send same arguments as client
1769 receives from server except for ID's. ID's are mapped to correct
1770 ID entry and that is returned. Also, if channel entry is not sent
1771 by server but the notify is for channel the channel entry is sent
1772 to application (otherwise application doesn't know that it is for
1773 channel (library gets it from packet's Destination ID)).
1775 * Added silc_client_remove_from_channels into client library to
1776 remove a client from all channels it has joined to. Used when
1777 received SIGNOFF notify from server. Added also new function
1778 silc_client_replace_from_channels to replace old ID entry with
1779 new ID entry on all channels. Used when received NICK_CHANGE
1782 * Fixed ID Cache list handling in silc_idlist_get_client in
1783 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1784 to get (or query) client by ID.
1786 * Updated TODO list.
1788 * Added connection authentication status message defined by the
1789 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1790 support for these into the code in client and server side.
1792 * Added generic function silc_client_send_command to send any command
1793 with variable argument list. Application should use this function
1794 to send commands if the command functions provided by the library
1795 does not suite for the application's user interface needs.
1797 * Added new `failure' client operation. Application is notified about
1798 received failure packet if client is executing a protocol. In this
1799 case the protocol's execution has failed.
1801 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1802 is required by the protocol.
1804 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1805 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1808 * Added status flag to SilcSKE object to indicate realtime status
1809 of the SKE protocol.
1811 * Application receives now exactly same command reply arguments as
1812 the library receives from server. However, if ID is received the
1813 corresponding ID entry is returned to the application (eg. Client
1814 ID is mapped to correct SilcClientEntry entry and that is returned).
1815 Changed command_reply client operation due to this change.
1817 * Changed all ID's in commands and in command replys as ID Payloads.
1818 Change affected both client and server side codes.
1820 All ID's sent in SILC network (with execption of ID's in SILC
1821 Packet header) are sent in ID Payload to support variable length
1824 * Server now notifies nick changes and notifies all clients on
1825 the channels about the new nickname (about the new Client ID,
1828 * Implemented CMODE command to change channel modes. Supports all
1829 channel modes defined by the protocol specs except ban and invite
1830 lists. (Also, private channel key mode is supported but support for
1831 setting private channel key in client is missing, thus, this mode
1832 has no effect on client side (except that server requires that the
1833 client uses private channel key and normal channel traffic does not
1836 Also, invite mode works per se, but INVITE command does not work
1837 yet correctly, so you can set channel as invite only channel but
1838 inviting clients to the channel does not work (it is yet to be
1839 thought what's the best way to do it).
1841 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1842 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1843 Implemented CUMODE command to change user's mode on the channel.
1844 Supports all modes defined by the protocol specs.
1846 * Added NAMES command reply to return users modes on the channel.
1848 * Removed unnecessary and slow ciphers from lib/silccrypt.
1850 * Set SO_KEEPALIVE option to connection sockets by default.
1852 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1854 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1855 redefined the Notify Payload into protocol specs.
1857 * Added silc_id_payload_parse_id to get ID directly from raw
1860 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1863 accept searching by Client ID as well.
1865 * Added support for LEAVE and SIGNOFF notify types in client library.
1867 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1868 to parse ID Payload from raw data.
1870 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Added flags parameter into silc_ske_assemble_security_properties
1873 function in lib/silcske/silcske.[ch].
1875 * Changed notify client operation to fit better for notify messages
1876 sent by server. The notify payload received from server is now
1877 passed to the application (after parsing it to SilcNotifyPayload).
1878 It is application's responsibility to retrieve the arguments
1879 from the payload and show the message the way it wants. The message
1880 sent by server is implementation specific.
1882 * Changed public keys to comply with the protocol specification.
1883 Old public keys are not supported anymore and are not compatible.
1885 * Removed nickname from Channel Payload as the latest draft removed
1886 it. The client must resolve the nickname from the NAMES command
1887 reply received when it joined the channel.
1889 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1891 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Fixed some errors in protocol specification drafts.
1895 * Created lib/silccore/silcnotify.c to implement Notify Payload
1896 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1897 generic payloads described by protocol specifications. The file
1898 includes implementations for ID Payload and Argument Payload.
1900 * Changed Command Payload implementation to use the new Argument
1901 Payload. Changed command_xxxx_payload to command_payload_xxxx
1902 to comply with SILC coding conventions.
1904 * Added suppport for Argument Payload handling in Notify Payload
1905 implementation as protocol requires it. Added the new support
1906 into server and client lib as well.
1908 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added support for multiple nicknames on same channel. [n] is
1911 added locally to the nickname if there are more than one same
1912 nicknames on the channel.
1914 * Server now sends all nicknames that matched WHOIS request.
1915 Client also shows the list received from server.
1917 * Added TOPIC command to client side. User can now set and show
1918 current topic on channel.
1920 * Added MOTD command to client and server. Also, server sends the
1921 motd when client connects to the server.
1923 * Changed version strings to comply ISO 8601.
1925 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Fixed protocol error handling in client library. It should now
1928 cope even if the SKE fails for some reason.
1930 * Made new protocol specification drafts for submitting to IETF.
1932 * Implemented TOPIC command to server in silcd/command.c.
1934 * Added two new notify types into lib/silccore/silcnotify.h:
1935 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1936 notify nickname change and topic setting/change on a channel.
1938 * API change of command_reply operation in client library. The
1939 application gets now the status type received from server as well.
1941 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1945 * Cras fixed and optimized the packet handling even further and
1946 it should work now. Minor change to the prototype of function
1947 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1949 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Added new function into lib/silcutil/silcschedule.[ch]:
1952 silc_schedule_with_fd to select() a specified fd. The function
1953 returns after timeout expires or data arrives or goes. The
1954 function is used by packet routines to wait that all data is
1955 received from network.
1957 * Fixed data reading from network in lib/silccore/silcpacket.c.
1958 The code now assures that all data is read from the fd and then
1959 continues packet processing. This was a bug fix since the code
1960 used to drop some data in some circumstances.
1962 * Added new function into lib/silcclient/client.[ch]:
1963 silc_client_start_key_exchange to start key exchange after
1964 connection has been established to server. The code internally
1965 now uses this funtion but its main purpose was to provide it
1966 for applications that perform their own connecting. After
1967 application has created a connection it merely calls this
1968 function to start the key exchange between client and server.
1969 The library takes care of everything else after that.
1971 Updated also lib/silcclient/README to explain the usage of
1974 * Do not send to application information that connection has
1975 been established. Application gets notified it by connect
1978 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Applied cras's patch to add silc_schedule_one function. The
1981 function runs scheduler once and returns.
1983 * Fixed the scheduler after cras messed it up. The timeout
1984 handling works now as it's supposed to work.
1986 * Added into lib/silccore/ silcnotify.h to include notify
1987 message types support. Changed silc_server_send_notify*
1988 functions, in server.[ch], to support those new notify types.
1989 Added the support for the notify types into client library,
1990 as well. Added new notify client operation into ops.h in
1993 * Changed silc_server_packet_send_to_channel to send normal
1994 packets instead of just channel message packets. The function
1995 is now used to send the notify packets to channels. It is not
1996 used to send channel message packets anymore, as server never
1999 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2000 va_arg()s as it seems to require it nowadays. I guess, if SILC
2001 is compiled with older va_arg() the new code should work anyway.
2003 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Splitted core library. Core library (lib/silccore) includes
2006 now only SILC protocol specific core (and common) components.
2007 Created new utility library (lib/silcutil) that includes more
2008 generic purpose stuff. The stuff for util library was taken
2009 from the old core library. This was minor and easy split.
2011 * Created SILC Client Library (lib/silcclient) that includes
2012 implementation of the SILC client without user interface. This
2013 was major move from silc/ directory. The code has been changed
2014 so that it is transparent towards the user interface. The
2015 silc/ directory includes now the same user interface as before
2016 and it uses the new client library. Read lib/silcclient/README.
2017 Basicly, the client library performs everything else related
2018 to SILC except user interface handling. Also, configuration
2019 files are considered to be part of user interface and library
2020 does not handle them.
2022 This change also changed a lot of structures, function naming etc.
2023 Most important change was that SilcClientWindow object was
2024 renamed to SilcClientConnection in the client library. Created
2025 also new file lib/silcclient/ops.h. Also added new files
2026 silc/local_command.[ch] and silc/client_ops.[ch].
2028 All these changes were made to make it easier for user interface
2029 designers to create what ever user interface for the SILC client
2032 It is also expected that the server will be moved to lib
2033 directory as well and SILC Server Library will be created;
2034 sometimes in the future.
2036 * Removed Local commands from lib/silccore/silccommand.h as
2037 they are application specific and new client library does not
2038 handle any of those anymore.
2040 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2041 old client implementation in silc/.
2043 * Added support for callback functions in SILC_LOG_* macros.
2044 Application can now set its own callbacks that will be called
2045 instead of using the default functions that will always print
2046 the debug messages to stderr (or stdout). Also, debugging can
2047 now be disabled by setting silc_debug to FALSE and re-enabled by
2048 setting it to TRUE. Note, that logging will still work even
2049 if debugging is disabled.
2051 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2052 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2053 silc_log_reset_debug_callbacks.
2055 * To enable debugging in silc client one must give now -d
2056 option on command line.
2058 * Changed silc_schedule_init to automatically allocate task queues
2059 if they are not allocated before calling it.
2061 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Added GMP 3.1 into math library.
2065 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2068 a channel in SILC network. The packet is used by servers and
2069 routers to notify other routers that user has left a channel.
2070 This little feature was missing until now. Added the feature
2071 to protocol specification as well.
2073 Added functions: silc_server_send_remove_channel_user and
2074 silc_server_remove_channel_user into server.[ch].
2076 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2077 lib/silccore/silcpacket.h. However, they are not implemented
2080 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2082 * Fixed joining to a channel and sending channel messages
2083 between server and router. The channel message sending should
2084 now work inside a cell.
2086 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Fixed the private message sending between server and router.
2089 The private message sending should now work inside a cell.
2091 * Added silc_server_replace_id into server.[ch] to replace
2092 existing ID in the SILC network.
2094 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2095 and silc_idlist_replace_server_id into idlist.[ch] in server.
2097 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Fixed the server to server connections. Server can again now
2100 connect to router. Router to router connections probably does
2103 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Added dynamic protocol registering support. Now protocols can
2106 registered and unregistered on the fly. Patch by cras.
2108 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Added lib/contrib directory to hold routines that some platforms
2111 don't have but are needed by SILC.
2113 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2114 into lin/contrib to provide getopt() and getopt_long() for
2115 those who don't have it.
2117 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Added AWAY command to client. When away message is set and
2120 client receives a private message packet the client automatically
2121 replies to the sender with the away message.
2123 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2124 bug seemed to be the cause of recent problems when compiling
2127 * Added version detection support to SKE protocol specification
2128 and added the new changes to the SKE implementation as well.
2129 There were other minor changes in the SKE protocol as well.
2131 Many changes in lib/silcske/silcske.[ch] and in
2132 lib/silcske/payload.[ch].
2134 * Added ^U functionality, clear input line. Patch from cras.
2136 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Mainly small bugfixes on core library. Fixed some debugging
2139 logging and buffer overflow in silclog.c.
2141 * Updated config.sub and config.guess on the distribution tree.
2143 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Added command lagging support in server. Client may execute
2146 commands now only once in two seconds.
2148 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Optimized packet reception. MAC computation and checking is now
2151 also more optimized. A lot previously duplicated code is now
2152 used as generic by both client and server.
2154 * Fixed key pair generation in clientutil.c
2156 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Added into lib/silccore/silcbufutil.[ch] new function;
2159 silc_buffer_realloc.
2161 * Moved generic packet sending/encryption functions to
2162 lib/silccore/silcpacket.[ch] from client and server. Some
2163 rewriting of the functions.
2165 * Moved all generic packet reception/decryption functions to
2166 lib/silccore/silcpacket.[ch] from client and server. The
2167 packet processing is now much cleaner in both client and server.
2168 These were major changes in both client and server.
2170 * Created many common functions in server to do packet sending.
2171 Previously code were duplicated a lot, this has been removed
2174 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Rewrote major parts of the ID cache system. Don't know
2177 whether it is better now or not but at least the API is more
2180 * Major rewrite on ID cache stuff on client because of the ID
2181 cache API changes. Added idlist.c to client.
2183 * Also major rewrite on ID cache stuff on server as well.
2184 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2185 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2186 in hand, instead they are all put into the ID cache system now.
2187 All server_idlist_* routines uses ID cache now instead of
2188 traversing its own lists (those lists does not exist anymore).
2189 SilcIDList though still exists. Also, SilcXXXEntry's are
2192 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Finally made the SKE implementation compliant to the protocol
2195 specification. All mp integers are now binary encoded as
2196 opposed being HEX encoded.
2198 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2201 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2202 functions: silc_[encode/decode]_pem. Also added function
2203 silc_encode_pem_file to PEM encode with newlines ('\n') for
2206 * SILC public keys are now encoded either PEM or binary. Same
2207 option is for private keys as well. By default private keys
2208 are binary encoded and public keys PEM encoded. Silly HEX
2209 encoding were removed.
2211 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2212 function to create fingerprints.
2214 * Fixed a bug in SHA1; does not change the original data anymore.
2216 * Partly implemented INFO command on client and server side.
2217 Fixed CLEAR command. Changes to SERVER command; show current
2218 server(s) when giving command without arguments. Added
2219 VERSION command to client.
2221 * Added check to server that unregistered connections cannot
2222 execute commands (unless it is specificly allowed).
2224 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Fixed screen refresh.
2228 * Fixed channel joining bug from client. On some circumstances
2229 client tried to join to a channel it had already joined.
2231 * Added public key verification process into client's protocol.c.
2232 The client now verifies the public key from user and saves
2233 it into ~./silc/serverkeys/ directory.
2235 Added into: clientutil.[ch]: silc_client_verify_server_key.
2237 * Changed SKE protocol's silc_ske_initiator_finish function
2238 to accept callback function that verifies the received public
2239 key. Removed old silc_ske_verify_public_key function.
2241 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2244 silc_pkcs_private_key[_data]_set.
2246 * Made the password and public authentication more cleaner in
2247 server's protocol.c.
2249 * Removed historic and obsolete protocol `channel_auth' from
2250 both client and server.
2252 * Removed wrong way of sending command status messages from
2253 server to client in server's command.c. The old way violated
2254 protocol specification.
2256 Changes to silccore/silccommand.[ch]: removed
2257 silc_command_encode_status_payload -> not needed anymore,
2258 changed silc_command_encode_payload_va to accept extra
2259 argument on variable argument list. The argument type must
2260 now be provided to the function. Also, added new function:
2261 silc_command_encode_reply_payload_va which is same as
2262 normal command_encode_payload_va except command status type
2263 is provided as extra argument.
2265 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added ~./silc directory handling. The directory includes the
2268 public and private keys for the client.
2270 Added silc_client_check_silc_dir, silc_client_create_identifier
2271 and silc_client_load_keys.
2273 * Implemented SILC protocol compliant public key. Added public
2274 and private key saving to and loading from files.
2276 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2277 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2278 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2279 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2280 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2282 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2283 silc_pkcs_load_[public/private]_key.
2285 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Added silc_server_get_route (route.[ch]) to get connection
2288 data for the fastest route for given ID.
2290 * Implemented INVITE command on client and server. The command
2291 were re-defined in the SILC Protocol Specification and the
2292 implementation now complies with the specification.
2294 * Implemented PING command on client and server.
2296 * Implemented NAMES command on client and server. The server side
2297 supports currently only normal server not router server yet.

2300 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Implemented LEAVE command on client and server.
2304 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2305 again. This change was made to the protocol as well. Server
2306 should not violate the protocol specification anymore.
2308 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
