1 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed MOTD command in the server to work in router environment.
5 * Fixed the MOTD command in the client library to support
6 the server argument in the command.
8 * Added `nickname_len' argument to the silc_idlist_add_client
9 in the server, as the `nickname' argument may be binary data
12 * Added silc_idlist_get_channels to return all channels from
15 * Implemented LIST command to the server. Affected file is
18 * Implemented the LIST command to the client library and on the
21 * Added [<user count>] argument to the LIST command reply.
22 With private channels the user count is not shown.
24 * Updated TODO and README.
26 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * The client entry's data.registered must be TRUE even with
29 global client entry on global client list. The data.registered
30 is used to check whether the client is anymore in the network,
31 for example with WHOWAS command so it must be valid.
33 * Fixed the WHOWAS command in the server. It now actually works
34 in router environment. Added function into silcd/command_reply.c
35 silc_server_command_reply_whowas_save.
37 * Added silc_idlist_purge function to the silcd/idlist.c
38 to periodically purge the ID Cache.
40 * Fixed INFO command in the server. It works now in router
41 environment. Added <server name> argument to the INFO command
42 reply. Updated the protocol specs.
44 * Fixed minor bug in silc_idcache_purge to not purge if the
47 * Fixed various bugs in WHOIS and IDENTIFY command handling as
48 they were buggy because of the WHOWAS information.
50 * Fixed local command MSG to handle the async resolving of
51 the remote client properly. It used to fail the first MSG.
52 Affected file silc/local_command.c.
54 * Added `data_len' field to SilcIDCache context.
56 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
58 * Update TODO. Todo in commands in the server.
60 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
63 used by routers as broadcast packet to inform other routers
64 about the changed user mode.
66 Implemented the notify handling in the server. Affected file is
67 silcd/packet_receive.c. Added the function
68 silc_server_send_notify_umode to the silcd/packet_send.[ch].
70 * Added new generic Channel Payload and deprecated the New Channel
71 Payload. The New Channel Payload is now the generic Channel
74 * Added new argument `mode' to the silc_server_send_new_channel
75 as it is required in the Channel Payload now.
77 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
78 and created a new and real SilChannelPayload to represent the
79 new generic Channel Payload. Implemented the encode/decode
80 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
82 * Added silc_server_get_client_channel_list to return the list
83 of channels the client has joined for WHOIS command reply.
84 Affected file silcd/server.[ch].
86 * Implemented the channel list sending in the WHOIS command reply
87 in server and in the client.
89 Implemented the channel list displaying on the user interface
90 as well. Affected file silc/client_ops.c.
92 * Added silc_channel_payload_parse_list to parse list of Channel
93 Payloads. It returns SilcDList list of SilcChannelPayloads.
94 Client for example can use this function to parse the list of
95 channels it receives in the WHOIS command reply. The caller
96 must free the list by calling silc_channel_payload_list_free.
97 Affected files lib/silccore/silcchannel.[ch].
99 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Added one new argument <user mode> to the WHOIS command reply
102 to return the mode of the user in SILC. Updated the protocol
105 Implemented it to the server and client.
107 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Fixed the mode printing on the user interface on joining.
110 Affected file silc/client_ops.c.
112 * Implemented the UMODE command and user modes in general to the
113 client library and to the user interface.
115 * Implemented the UMODE command to the server.
117 * The server now sends UNKNOWN_COMMAND error status if client sends
118 unknown command. Affected file silcd/command.c.
120 * All server commands now handle the command identifier the right
121 way when sending the command reply to the client. The client can
122 use to identify the command replies with the identifier.
124 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Added silc_server_get_client_route to resolve the route to
127 the client indicated by the client ID. Affected file is
130 * Added silc_server_relay_packet as general function to relay
131 packet to arbitrary destination. This deprecates functions
132 like _send_private_message_key, _relay_notify etc. Affected
133 file is silcd/packet_send.[ch].
135 Removed silc_server_send_key_agreement,
136 silc_server_send_private_message_key and
137 silc_server_packet_relay_notify functions from the file
138 silcd/packet_send.[ch].
142 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
143 server. Affected file silcd/packet_receive.[ch].
145 * Implemented the KILL command to the client. Implemented the
146 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
147 Affected files lib/silcclient/command[_reply].c and
148 lib/silcclient/client_notify.c. Implemented the KILL notify
149 printing in the user inteface.
151 * Fixed a lot silc_parse_nick memory leaks from the client
152 library in the file lib/silcclient/command.c.
154 * Changed the silc_server_send_notify_on_channels's `sender'
155 argument from SilcSocketConnection to SilcClientEntry to
156 check the sender as entry and not as connection object and not
157 to send to the client provided as argument. The affected file
158 is silcd/packet_send.[ch].
160 * The notify packets that are destined directly to the client used
161 to not to be processed by the server. Now changed that and the
162 server processes all notify packets. After relaying the packet
163 to the client the notify packet is processed in the server.
165 * The silc_server_free_client_data now checks whether there is
166 pending outgoing traffic for the client and purges the data to
167 the network before removing the client entry.
169 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
172 an client is killed from the SILC Network. Updated the protocol
175 Added new function silc_server_send_notify_killed to the
176 silcd/packet_send.[ch].
178 * Added function silc_server_packet_relay_notify to relay notify
179 packets that are destined directly to a client. In this case
180 the server does not process the notify packets but merely relays
181 it to the client. Affected file silcd/packet_send.[ch].
183 Added also silc_server_packet_process_relay_notify to check
184 whereto relay the notify. Affected file is
185 silcd/packet_receive.[ch].
187 * Implemented the KILL command to the server.
191 * Added the backup schema desgined last fall to the protocol
192 specs for everyone to see. The specification is in the
193 *-spec-xx.txt draft and the packet type definitions for the
194 backup routers is in *-pp-xx.txt draft. Thusly, added also
195 new packet type SILC_PACKET_CELL_ROUTERS.
197 * A big security problem in the implementation discovered. The
198 signoff of an client did not cause new channel key generation
199 which it of course should've done. The channel keys must be
200 always re-generated when client leaves (or signoffs) the channel.
201 The silc_server_remove_from_channels funtion now handles
202 the channel key re-generation.
204 * Added `sender' argument to the silc_server_send_notify_on_channels
205 to not to send the client provided as argument. Affected file
206 silcd/packet_send.[ch].
208 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Implemented OPER and SILCOPER commands into the server and
213 * Added silc_auth_verify and silc_auth_verify_data to verify
214 the authentication directly from the authentication payload.
215 It supports verifying both passphrase and public key based
216 authentication. Affected file lib/silccore/silcauth.[ch].
218 * Added `hash' field to the SilcIDListData structure. It is the
219 hash negotiated in the SKE protocol. Affected file is
222 * Slight redesigning of the SilcAuthPayload handling routines.
223 Do not send SilcPKCS but SilcPublicKey as argument.
225 * Implemented the public key authentication support to the
226 serverconfig. The public key is loaded fromthe provided path
227 and saved as authentication data to void * pointer. Thus,
228 changed the unsigned char *auth_data to void *auth_data;
230 * Fixed SHUTDOWN command to send the reply before the server
231 is shutdown. :) Affected file silcd/command.c.
233 * Fixed fatal bug in CONNECT command. The hostname was invalid
234 memory and server crashed. Affected file silcd/command.c.
236 * Fixed fatal bug in CLOSE command. The server_entry became
237 invalid but was referenced later in the command. Affected file
240 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
242 * Fixed fatal bug in failure packet handling. Server ignored
243 the failure and thus crashed when it came.
247 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
250 that the command may be executed only once in (about) 2 seconds.
251 The old SILC_CF_LAG flag is same but allows command bursts up
252 to five before limiting.
254 Added the support for CF_LAG and CF_LAG_STRICT flags to the
255 server code. Various commands now includes the CF_LAG_STRICT
256 flag to disallow any kind of miss-use of the command.
258 * Fixed the silc_buffer_unformat to not to allocate any data
259 if the length of the data is zero. It used to allocate the
260 length + 1. Affected file lib/silcutil/silcbuffmt.c.
262 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Changed the format of AdminConnection configuration section
265 in the server. Added username of the admin to the format.
266 Affected files silcd/serverconfig.[ch].
268 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
269 to return admin configuration data by host, username and/or
272 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Implemented WHOWAS command to the server. Added the functions:
276 silc_server_command_whowas_parse,
277 silc_server_command_whowas_send_reply,
278 silc_server_command_whowas_from_client and
279 silc_server_command_whowas_from_server
281 * Added <Client ID> argument to the WHOWAS command reply. Updated
282 the protocol specs accordingly.
284 * Implemented WHOWAS command and command_reply to the client
287 Implemented the WHOWAS printing on the user interface.
289 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Added new argument to the WHOWAS command reply, the real name.
292 It is an optional argument. Updated the protocol specs.
294 * Added SilcIDCacheDestructor callback that is registered when
295 the SilcIDCache is allocated. The callback is called when
296 an cache entry in the ID Cache expires, or is purged from the
297 cache. Added into lib/silccore/idcache.[ch].
299 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
300 to destruct the client entries when the cache entry expires.
301 Other ID Cache's in server and in the client library ignores
304 * If the ID Cache entry's `expire' field is zero then the entry
305 never expires. Added boolean `expire' argument to the
306 silc_idcache_add function in the lib/silccore/idcache.[ch].
307 If it is TRUE the default expiry value is used.
309 * Added silc_server_free_client_data_timeout that is registered
310 when client disconnects. By default for 5 minutes we preserve
311 the client entry for history - for WHOWAS command.
313 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Added support to the server to enforce that commands are not
316 executed more than once in 2 seconds. If server receives
317 commands from client more frequently, timeout is registered
318 to process the commands. Affected file silcd/command.c.
319 Added new function silc_server_command_process_timeout.
321 * Changed NICK_NOTIFY handling in client library to check that
322 if the client's nickname was changed, so there is no need to
323 resolve anything from the server.
325 * Removed error printing from the WHOIS and IDENTIFY commands.
326 If error occurs then it is ignored silently in the client library.
327 The application, however, may map the received error to
328 human readable error string. The application currently maps
329 the NO_SUCH_NICKNAME error to string.
331 * Made the command status message public to the application. Moved
332 them from lib/silcclient/command_reply.c to
333 lib/silcclient/command_reply.h. The application can map the
334 received command status to the string with the
335 silc_client_command_status_message function.
337 * Added check to the server to check that client's ID is same
338 as the Source ID in the packet the client sent. They must
341 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added dist-bzip hook to the Makefile.am to make bzip2
344 compressed distributions.
346 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Server now enforces the maximum length for the nickname and
349 the channel as protocol specification dictates. 128 bytes for
350 nickname and 256 bytes for channel name.
352 * Moved the WHOIS printing to the application. The client libary
353 does not print out the WHOIS information anymore, the application
354 must do it. Renamed silc_client_command_reply_whois_print to
355 the silc_client_command_reply_whois_save.
357 The client's idle time is also sent to the application now, and
358 the idle is shown on screen.
360 * Added silc_client_command_reply_identify_save to save the
361 received IDENTIFY entries.
363 * Do not check for channel private keys in message sending and
364 reception if the channel does not have the PRIVKEY mode set.
365 Affected file lib/silclient/client_channel.c.
367 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
370 just surfaced after chaning the JOIN procedure.
372 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Added silc_client_get_clients_by_list to get client entries
375 from Client ID list, that is returned for example by JOIN
376 and USERS command replies. The application should use this
377 function for example when JOIN command reply is received to
378 resolve the clients already on the channel (library does not
379 do that anymore as USERS command reply is not used in the JOIN
380 procedure anymore). Affected files lib/silcclient/silcapi.h and
381 lib/silcclient/idlist.c.
383 * JOIN command reply and USERS command reply returns now SilcBuffer
384 pointers instead of unsigned char pointers when returning
385 the client list and mode list.
387 * Added <Client ID> argument to the JOIN command reply, mainly
388 for the server to identify for which client the command was
389 originally sent. Updated protocol specs accordingly.
391 * Added SilcDlist private_key pointer to the SilcChannelEntry
392 in the client to support the channel private keys. Affected
393 file is lib/silcclient/idlist.h.
395 * Added SilcChannelPrivateKey argument to the function
396 silc_client_send_channel_message so that application can choose
397 to use specific private ke if it wants to. If it is not provided,
398 the normal channel key is used, unless private keys are set.
399 In this case the first (key that was added first) is used
400 as the encryption key.
402 * Implemented the support for channel private key handling.
403 Implemented the following functions:
405 silc_client_add_channel_private_key,
406 silc_client_del_channel_private_keys,
407 silc_client_del_channel_private_key,
408 silc_client_list_channel_private_keys and
409 silc_client_free_channel_private_keys
411 Affected file lib/silcclient/client_channel.c.
413 * Added the support for the private keys in the channel message
414 sending and encryption and in the message reception and
415 decryption. Affected funtions are
416 silc_client_send_channel_message and silc_client_channel_message.
418 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Added SKE's key verify callback to the client library's
421 KE protocol context. Affected files lib/silcclient/protocol.[ch].
423 * Removed the statement that server (or router) must send USERS
424 command reply when joining to the channel so that the client
425 knows who are on the channel. Instead, the client list and
426 client's mode list is now sent in the JOIN command reply to the
427 client who joined channel. This is better solution.
429 * Added function silc_server_get_users_on_channel and function
430 silc_server_save_users_on_channel to the silcd/server.[ch].
432 * Removed function silc_server_command_send_users from the
435 * Do not show topic on the client library anymore. The topic is
436 sent in the command reply notify to the application and the
437 application must show the topic now.
439 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added client searching by nickname hash into the IDENTIFY and
442 WHOIS commands in the server as they were clearly missing from
443 them. Affected file is silcd/command.c.
445 * Fixed a bug in private message receiving in the client library.
446 The remote ID was freed and it wasn't supposed, now it is
449 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * Minor fix to the channel payload; allocate the data area, as it
452 needs to be of specific length.
454 * If the key agreement port is zero then the operating
455 system will define the bound port. Affected files are
456 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
458 * Added new function silc_channel_payload_decrypt into the file
459 lib/silccore/silcchannel.[ch].
461 * Moved the channel message etc, check from silc_packet_decrypt
462 to applications. The library calls now a generic
463 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
464 when the packet is either normal or special. This was done to
465 allow more wide range of checking that was not allowed when
466 the code was in library. Now applications can do virtually any
467 checks to the packet and return to the library the decision how
468 the packet should be processed. Affected files are
469 lib/silccore/silcpacket.[ch].
471 Added silc_server_packet_decrypt_check to the server and
472 silc_client_packet_decrypt_check to the client library.
474 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
475 to send with specified source and destination information.
477 * Channel message delivery between routers was broken after the
478 channel key distribution was fixed earlier. The channel key
479 was used be to distributed to other routers as well which is not
480 allowed by the protocol. Now this is fixed and channel keys
481 really are cell specific and the channel message delivery between
482 routers comply with the protocol specification.
484 * Fixed various commands in server to check also the global list
485 for the channel entry and not just the local list. The affected
486 file silcd/command.c.
488 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Added assert()s to buffer formatting and unformatting routines
491 to assert (if --enable-debug) when error occurs. Affected
492 file: lib/silcutil/silcbuffmt.c.
494 * Changed to auto-reconnect to check whether the remote host is
495 router and register the re-connect timeout if it is. It used
496 to check that whether we are normal server, but router must do
497 auto-reconnect with another router as well. Affected file
500 * Removed the [<key len>] option from CMODE command as the cipher
501 name decides the key length, nowadays. See the defined ciphers
502 from the protocol specification.
504 * Added [<hmac>] option to the CMODE command to define the HMAC
505 for the channel. Added SILC_CMODE_HMAC channel mode.
507 * Added [<hmac>] option for the JOIN command so that user can
508 select which HMAC is used to compute the MACs of the channel
511 * Added Hmac field to the Channel Message Payload. The integrity
512 of plaintext channel messages are now protected by computing
513 MAC of the message and attaching the MAC to the payload. The
514 MAC is encrypted. Now, it is clear that this causes some
515 overhead to the size of the packet but rationale for this is that
516 now the receiver can verify whether the channel message decrypted
517 correctly and also when private keys are set for the channel the
518 receiver can decrypt the packet with several keys and check from
519 the MAC which key decrypted the message correctly.
521 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
522 lib/silccrypt/silccipher.[ch].
524 * Added silc_hash_len to return the digest length into the
525 lib/silcrypt/silchash.[ch].
527 * Rewrote parts of Silc Channel Payload interface in the
528 lib/silccore/silcchannel.[ch]. The encode function now also
529 encrypts the packet and parse function decrypts it.
531 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Fixed a minor formatting bug in the SKE's key material processing.
534 It actually might have processed the keys wrong way resulting
537 * Redefined the mandatory HMAC algorithms and added new algorithms.
538 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
539 and hmac-md5 truncated to 96 bits. The mandatory is now
540 hmac-sha1-96. Rest are optional (including the one that used
541 to be mandatory). Rationale for this is that the truncated HMAC
542 length is sufficient from security point of view and can actually
543 make the attack against the HMAC harder. Also, the truncated
544 HMAC causes less overhead to the packets. See the RFC2104 for
547 * Added new [hmac] configuration section. The SKE used to use
548 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
549 is of course wrong. The official names that must be proposed in
550 the SKE are the ones defined in the protocol specification
551 (hmac-sha1-96 for example). The user can configure any hmac
552 using any hash function configured in the [hash] section. At
553 least, the mandatory must be configured.
555 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
557 * Added HMAC list to the SKE proposal list. It has now both
558 hash algorithm list and HMAC list. This makes the protocol
559 incompatible with previous versions. The SKE now seems to work
560 the way it is supposed to work, for the first time actually.
562 * Defined plain Hash algorithms to the protocol specification.
565 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * Implemented support for key agreement packets into the server.
568 Added functions silc_server_key_agreement and
569 silc_server_send_key_agreement. Other than these functions,
570 server has nothing to do with this packet.
572 * Added support for private message key packets into the server.
573 Added functions silc_server_private_message_key and
574 silc_server_send_private_message_key.
578 * Changed the silc_[client|server]_protocol_ke_set_keys to be
579 called in the protocol's final callback instead in the END
580 protocol state. This makes a little more sense and in the same
581 time in client we can use the same protocol routines for normal
582 key exchange and to key agreement packet handling as well.
584 * Added to both client's and server's KE protocol context the
585 SilcSKEKeyMaterial pointer to save the key material. We will
586 bring the key material to the protocol's final callback by doing
587 this. The final callback must free the key material.
589 * Added SKE's packet_send callback into client's KE protocol
590 context so that the caller can choose what packet sending function
591 is used. This way we can use different packet sending when
592 doing normal SKE when doing key agreement packet handling (in
593 the key agreement packet handling we do not want to encrypt
596 * Implemented the responder side of the key agreement routines
597 in the client. The client can now bind to specified port and
598 accept incoming key negotiation. The key material is passed
599 to the application after the protocol is over.
601 * Implemented the processing of incoming Key Agreement packet
602 in the client. Added function silc_client_key_agreement to
605 * Implemented the intiator side of the key agreement routines
606 in the client. The client can now initiate key agreement with
607 another remote client. The key material is passed to the
608 application after the protocol is over.
610 * Created client_keyagr.c to include all the key agreement
613 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
614 SILC_TASK_CALLBACK except that it is not static.
616 * Created client_notify.c and moved the Notify packet handling
617 from the client.[ch] into that file.
619 * Created client_prvmsg.c and moved all private message and
620 private message key routines from the client.[ch] into that file.
622 * Create client_channel.c and moved all channel message and
623 channel private key routines from the client.[ch] into that file.
625 * Changed silc_client_get_client_by_id_resolve to resolve with
626 WHOIS command instead of IDENTIFY command, in the file
627 lib/silclient/idlist.c.
629 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Implemented the SKE's responder side to the Client library.
633 * When FAILURE is received to the protocol do not trust it
634 blindly. Register a timeout to wait whether the remote closes
635 the connection as it should do it, only after that process the
636 actual failure. This was changed to both client and server.
638 * Added client_internal.h to include some of the structures
639 there instead of client.h in lib/silcclient/.
641 * Added function silc_task_unregister_by_callback to unregister
642 timeouts by the callback function.
644 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Some "Incomplete WHOIS info" errors has been appearing on the
647 log files. Took away the entry->userinfo check from WHOIS
648 reply sending. The entry->userinfo is now " " if client did not
649 provide one. I thought this was fixed earlier but something
650 is wrong still. Let's see if the error still appears.
652 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Fixed a minor bug in the login when the channel key is
655 re-generated in the server. It used to generate the key in
656 wrong order and thus caused problems in the channel traffic.
658 * Fixed a minor bug in channel key distsribution after
659 KICK command. The key was not sent to the router even though
662 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * Added silc_ske_process_key_material_data as generic routine
665 to process any key material as the SILC protocol dictates. The
666 function is used by the actual SKE library but can be used by
667 applications as well. This relates to the private message keys
668 and the channel private keys since they must be processed the
669 same way the normal SILC session keys. The protocol dictates
670 this. Affected files: lib/silcske/silcske.[ch].
672 Added also silc_ske_free_key_material to free the
673 SilcSKEKeyMaterial structure.
675 * Defined silc_cipher_set_key function to set the key for
676 cipher without using the object's method function. The affected
677 files: lib/silccrypt/silccipher.[ch].
679 * Implemented silc silc_client_add_private_message_key,
680 silc_client_add_private_message_key_ske,
681 silc_client_del_private_message_key,
682 silc_client_list_private_message_keys and
683 silc_client_free_private_message_keys functions in the
686 Added functions silc_client_send_private_message_key to send
687 the Private Message Key payload and silc_client_private_message_key
688 to handle incoming Private Message Key payload.
690 * Added Cipher field to the Private Message Key payload to set
691 the cipher to be used. If ignored, the default cipher defined
692 in the SILC protocol (aes-256-cbc) is used.
694 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Removed lib/silcclient/ops.h file.
698 Redefined parts of the SILC Client Library API. Created new
699 file silcapi.h that deprecates the ops.h file and defines the
700 published Client Library API. Defined also private message key
701 API and channel private key API into the file.
703 This is the file that the application must include from the
704 SILC Client Library. Other files need not be included by
705 the application anymore.
707 * Added new key_agreement client operation callback and also
708 defined the Key Agreement library API for the application.
710 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
713 is used by clients to request key negotiation between another
714 client in the SILC network. If the negotiation is started it
715 is performed using the SKE protocol. The result of the
716 negotiation, the secret key material, can be used for example
717 as private message key.
719 Implemented the Key Agreement payload into the files
720 lib/silccore/silauth.[ch].
722 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Redefined ciphers for the SILC protocol. Added some new ciphers
725 and defined the key lengths for the algorithms. Changed the
726 code accordingly. The default key length is now 256 bits.
728 * Fixed SKE key distribution function silc_ske_process_key_material
729 when the key length is more than 128 bits. The default key
730 length in SILC is now 256 bits.
732 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
733 to indicate unsupported algorithm.
735 * Renamed rijndael.c to aes.c and all functions as well.
737 * Fixed a long standing channel key setting bug in client library.
738 Weird that it has never surfaced before.
740 * Fixed bug in channel deletion. If the entire channel is removed
741 then it must also delete the references of the channel entry
742 from the client's channel list as the client's channel entry and
743 the channel's client entry share same memory.
745 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Implemented CONNECT and SHUTDOWN commands in the client.
749 * Implemented CLOSE command to the client.
751 * Added the function silc_idlist_find_server_by_name into the
752 files silcd/idlist.[ch].
754 Added the function silc_idlist_find_server_by_conn into the
755 files silcd/idlist.[ch].
757 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * DIE command was renamed to SHUTDOWN. Updated the both code
762 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
763 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
765 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
768 * Added function silc_server_create_connection function to create
769 connection to remote router. My server implementation actually
770 does not allow router to connect to normal server (it expects
771 that normal server always initiates the connection to the router)
772 so the CONNECT command is only good for connecting to another
775 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
778 or some other client was kicked from the channel.
780 Implemented the handling of the notify type to both client
783 Implemented silc_server_send_notify_kicked to send the KICKED
784 notify. It is used to send it to the server's primary router.
786 * Implemented the KICK command into server and client.
788 * Added `query' argument to the silc_idlist_get_client function
789 to indicate whether to query the client from server or not if
792 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
793 to indicate that the client is not channel founder.
797 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Removed the rng context from SilcPacketContext structure and
800 changed that the packet routine uses the Global RNG API.
802 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Added support for quit message that client can "leave" on the
805 channel when it quits the SILC. It is ditributed inside the
806 SILC_NOTIFY_TYPE_SIGNOFF notify type.
808 Added silc_server_free_client_data that will take the
809 signoff message as argument.
811 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
813 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Updated parts of the protocol specification to keep it up
818 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
821 payloads in one packet.
823 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
824 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
825 use now the new List flag.
827 * Also deprecated the following packet types: REPLACE_ID,
828 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
830 * Added list support for Notify packet in server.
832 * Added silc_server_send_notify_channel_change to send the
833 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
834 the silc_server_send_replace_id.
836 * Added silc_server_send_notify_nick_change to send the
837 NICK_CHANGE notify type. Deprecates the function
838 silc_server_send_replace_id.
840 * Added silc_server_send_notify_join to send the JOIN notify type.
841 Deprecates the function silc_server_send_new_channel_user.
843 * Added silc_server_send_notify_leave to send LEAVE notify type.
844 Deprecates the function silc_server_send_remove_channel_user.
846 * Added silc_server_send_notify_cmode and
847 silc_server_send_notify_cumode to send CMODE and CUMODE notify
848 types. Deprecates the silc_server_send_set_mode function.
850 * Added SERVER_SIGNOFF notify type to indicate that server has
851 quit. This means that all clients on the channel from that
852 server will drop. This can be also used when netsplit happens.
854 Deprecated REMOVE_ID packet type since it is not needed anymore
857 Added silc_server_send_notify_server_signoff to send the
858 SERVER_SIGNOFF notify type. Deprecates the function
859 silc_server_send_remove_id.
861 Added also silc_server_send_notify_signoff to send the
864 * Employed the PKCS #1. It is the mandatory way to do RSA in the
865 SILC protocol from this day on. Changed the protocol
866 specification as well.
868 * Added silc_server_send_notify_topic_set to send TOPIC_SET
869 notify type. It is used between routers to notify about
870 topic changes on a channel.
872 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
875 * Partly updated the protocol specification to comply with the
876 changes now made. It is still though a bit outdated.
878 * The JOIN notify type now takes one extra argument <Channel ID>.
879 The packet used to be destined to the channel but now the
880 JOIN type may be sent as list thus it is impossible to
881 destine it to any specific channel. By adding this argument
882 it is again possible.
884 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Added CREDITS file. The CHANGES and CREDITS file will appear
887 in the distribution as well.
889 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
892 types in the server's silcd/packet_receive.c.
894 * Implemented CMODE and CUMODE to work in router environment.
896 * Fixed minor encoding and decoding buglet from the
897 lib/silccore/silcmode.c.
899 * Fixed buffer overflow from lib/silcclient/command.c in USERS
902 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
904 * Changed all SilcConfigServer* and silc_config_server* to
905 SilcServerConfig* and silc_server_config*, respectively.
908 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Associated the ID (client or server ID) to the Authentication
911 Payload to avoid any possibility of forging. Updated the
912 protocol specification and the code accordingly.
914 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * The RSA key length is now save to the RsaKey context in the
917 key generation process in lib/silccrypt/rsa.c. The key length
918 is now used to figure out the maximum size of the block allowed
919 to be encrypted/signed.
921 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
922 is equivalent to the silc_mp_mp2bin but does not allocate any
925 * Changed silc_mp_mp2bin API to take length argument. If it is
926 non-zero then the buffer is allocated that large. If zero, then
927 the size is approximated using silc_mp_sizeinbase, which however
930 * Created Global RNG API which is global RNG that application can
931 initialize. After initializing, any routine anywhere in the
932 code (including library) can use RNG without allocating a new
933 RNG object. This was done to allow this sort of use of the
934 RNG in code that has no chance to allocate RNG object. All
935 applications currently allocate this and many routines in the
936 library use this. Affected file lib/silccrypt/silcrng.[ch].
938 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
939 it to use the Global RNG API.
941 * Defined Authentication Payload into protocol specification that
942 is used during SILC session to authenticate entities. It is
943 used for example by client to authenticate itself to the server
944 to obtain server operator privileges.
946 Implemented this payload into the lib/silccore/silcauth.[ch].
947 Implemented also routines for public key based authentication
948 as the new protocol specification dictates.
950 Moved definitions of different authentication methods from
951 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
953 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
954 silc_pkcs_verify and silc_pkcs_sign_with_hash and
955 silc_pkcs_verify_with_hash functions into the file
956 lib/silccrypt/silcpkcs.[ch].
958 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * The client entry's userinfo pointer must be always valid.
961 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
962 will fail since it requires the userinfo. Now, the userinfo
963 is allocated as "" if actual userinfo does not exist. Actually,
964 it must exist and it is totally Ok to drop client connections
965 that does not announce the userinfo. However, we will make
966 this workaround for now.
968 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
969 to return the remote port by socket.
971 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
974 SILC_SERVER_PENDING_EXEC and added an new macro
975 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
976 data or when error occurs while processing the pending command.
978 Added new argument `destructor' into silc_server_command_pending
979 and to the SilcServerCommandPending object. This destructor is
980 now called after calling the pending callback or if error occurs
981 immediately. If error occurs the actual pending callback won't
982 be called at all - only the destructor. The destructor may be
983 NULL if destructor is not needed.
985 All this applies for client library code as well. Similar
986 changes were made there as well for the pending commands.
988 In the client, the application must now allocate the
989 SilcClientCommandContext with the silc_client_command_alloc
992 * Added reference counter to the SilcServerCommandContext. Added
993 function silc_server_command_alloc and silc_server_command_dup
996 Same type of functions added to the client library for the same
999 * Removed the cmd_ident from IDListData away since it is now
1000 global for all connections. It is the command identifier used
1001 in command sending and with pending commands. The affected file
1004 * Added reference counter to the SilcSocketConnection objecet to
1005 indicate the usage count of the object. The object won't be
1006 freed untill the reference counter hits zero. Currently only
1007 server uses this, and client ignores it. The client must be
1008 set to use this too later. The affected files are
1009 lib/silccore/silcsockconn.[ch]. Added also the function
1010 silc_socket_dup to increase the reference counter.
1012 This was mainly added because it is possible that the socket
1013 is removed underneath of pending command or other async
1014 operation. Now it won't be free'd and proper DISCONNECTING
1015 flags, etc. can be set to avoid sending data to connection that
1016 is not valid anymore.
1018 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1019 the connection. After that it sets SILC_SET_DISCONNECTED.
1020 It is, however, possible that the socket data is not still freed.
1021 The silc_server_packet_process now checks that data is not
1022 read or written to connection that is DISCONNECTED. The socket
1023 get's freed when the reference counter hits zero.
1025 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Changed the client operation API: channel_message operation's
1028 `sender' is now the client entry of the sender, not the nickname
1029 and the `channel' is the channel entry, not the channel name.
1031 In the private_message operation the `sender' is now also the
1032 client entry of the sender not the nickname.
1034 Affected file is lib/silcclient/ops.h and all applications
1035 using the client operations.
1037 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Moved the calling of ops->connect() from connect_to_server_final
1040 into receive_new_id functin since that is the point when the
1041 client is actually allowed to send traffic to network. The
1042 affected file is lib/silcclient/client.c.
1044 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1047 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1048 (if needs broadcasting) instead of broadcasting the packets one
1049 by one which would make a burst in the network traffic.
1051 * Added `broadcast' argument to the functions in silcd/server.[ch]
1052 silc_server_create_new_channel[_with_id] to indicate whether
1053 to send New Channel packet to primary router.
1055 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Added new function into the silcd/server.[ch] files:
1058 silc_server_create_new_channel_with_id to create new channel with
1059 already existing Channel ID.
1061 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1062 lib/silccore/silcpacket.h. This packet is used t send list of
1063 Set Mode payloads inside one packet. Server uses this to set
1064 the modes for the channels and clients on those channels, that it
1065 announced to the router when it connected to it. The protocol
1066 specification has been updated accordingly.
1068 * The silc_server_new_channel did not handle the packet coming
1069 from normal server as it normally does not send that. However,
1070 when it announces its channels it does send it. Implemented
1071 the support for that.
1073 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1074 into the file lib/silccore/id.h.
1076 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Fixed memory leaks in the functions silc_idlist_del_client,
1079 silc_idlist_del_channel and silc_idlist_del_server in the file
1080 silcd/idlist.c. All of those leaked like a sieve.
1082 * Fixed some small memory leaks in the client's function
1083 silc_client_notify_by_server.
1085 * Added functions into silcd/server.c: silc_server_announce_clients,
1086 silc_server_announce_channels and silc_server_announce_server.
1087 These functions are used by normal and router server to announce
1088 to its primary router about clients, channels and servers (when
1089 router) that we own. This is done after we've connected to the
1092 These functions effectively implements the following packet types:
1093 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1094 and SILC_PACKET_NEW_ID_LIST.
1096 * Added new functions into the silcd/packet_receive.[ch]:
1097 silc_server_new_id_list, silc_server_new_channel_list and
1098 silc_server_new_channel_user_list to handle the incoming
1099 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1101 * Added support of changing Channel ID in the function
1102 silc_server_replace_id. If the server that announces a channel
1103 to the router already exists in the router (with same name but
1104 with different Channel ID), router is responsible to send
1105 Replace ID packet to the server and force the server to change
1106 the Channel ID to the one router has.
1108 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1109 client that the Channel ID has been changed by the router. The
1110 normal server sends this to the client. Client must start using
1111 the new Channel ID as the channel's ID.
1113 Implemented handling of this new type into lib/silcclient/client.c
1114 into the function silc_client_notify_by_server.
1116 * Added new function silc_idlist_replace_channel_id into the files
1117 silcd/idlist.[ch] to replace the Channel ID.
1119 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Call silc_server_command_identify_check always when processing
1122 the IDENTIFY command in silcd/command.c
1124 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1127 send keepalive packets. The packet can be sent by clients,
1128 servers and routers.
1130 Added function silc_socket_set_heartbeat into the file
1131 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1132 If not set, the heartbeat is not performed. The actual
1133 heartbeat is implemented in the low level socket connection
1134 library. However, application is responsible of actually
1137 Added silc_server_send_heartbeat to send the actual heartbeat
1138 packet into silcd/packet_send.[ch]. Server now performs
1139 keepalive with all connections.
1141 * Added silc_task_get_first function into lib/silcutil/silctask.c
1142 to return the timeout task with shortest timeout. There was a bug
1143 in task unregistration that caused problems. TODO has been
1144 updated to include that task system must be rewritten.
1146 * The client library will now resolve the client information when
1147 receiving JOIN notify from server for client that we know but
1148 have incomplete information.
1150 * Rewrote parts of silc_server_remove_from_channels and
1151 silc_server_remove_from_one_channel as they did not remove the
1152 channel in some circumstances even though they should've.
1154 * Encryption problem encountered in server:
1156 The LEAVE command used to send the Channel Key packet to the
1157 router immediately after generating it. However, the code
1158 had earlier sent Remove Channel user packet but not immediately,
1159 ie. it was put to queue. The order of packets in the router
1160 was that Channel Key packet was first and Remove Channel User
1161 packet was second, even though they were encrypted in the
1162 reverse order. For this reason, MAC check failed. Now, this
1163 is fixed by not sending the Channel Key packet immediately but
1164 putting it to queue. However, this is more fundamental problem:
1165 packets that are in queue should actually not be encrypted
1166 because packets that are sent immediately gets encrypted
1167 actually with wrong IV (and thus MAC check fails). So, packets
1168 that are in queue should be encrypted when they are sent to
1169 the wire and not when they put to the queue.
1171 However, the problem is that the current system has not been
1172 designed to work that way. Instead, the packet is encrypted
1173 as soon as possible and left to the queue. The queue is then
1174 just purged into wire. There won't be any fixes for this
1175 any time soon. So, the current semantic for packet sending
1178 o If you send packet to remote host and do not force the send
1179 (the packet will be in queue) then all subsequent packets to the
1180 same remote host must also be put to the queue. Only after the
1181 queue has been purged is it safe again to force the packet
1184 o If you send all packets immediately then it safe to send
1185 any of subsequent packets through the queue, however, after
1186 the first packet is put to queue then any subsequent packets
1187 must also be put to the queue.
1189 Follow these rules and everything works fine.
1191 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Added new function silc_server_remove_clients_by_server to
1194 remove all client entries from ID list when the server connection
1195 is lost. In this case it is also important to invalidate all
1196 client entires as they hold the invalid server entry. This
1197 fixes fatal bug when server has lost connection and will reconnect
1200 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Made some sanity checks to silc_server_daemonise like to check
1203 whether the requested user and group actually exists.
1205 * Added sanity check to SKE's silc_ske_responder_finish to check
1206 that the public and private key actually is valid.
1208 * Invalidate the client's nickname when receiving Replace ID
1209 packet and the Client ID is being replaced. This means that the
1210 server will query the nickname if someone needs it (client)
1213 * Sort the ID Cache in client library when the ID Cache data
1214 has changed (needs sorting).
1216 * Do not allow for SILC client to create several connections to
1217 several servers. The client does not support windows right now
1218 and generating multiple connections causes weird behaviour.
1220 Irssi-silc client does support windows and can handle several
1221 connections without problems, see: www.irssi.org and SILC plugin.
1223 * Fixed some places where client was added to the IDList. The
1224 rule of thumb is following (in order to get everything right):
1225 If the client is directly connected local client then the
1226 `connection' argument must be set and `router' argument must be
1227 NULL to silc_idlist_add_client function. If the client is not
1228 directly connected client then the `router' argument must
1229 bet set and the `connection' argument must be NULL to the
1230 silc_idlist_add_client function.
1232 * The funtion silc_server_packet_send_local_channel actually did
1233 not check whether the client was locally connected or not. It
1234 does that now. Fixed a bug related to LEAVE command.
1236 * Fixed Remove Channel User payload parsing bug in server's
1237 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1239 * The server's silc_server_save_channel_key now checks also the
1240 global ID list for the channel as it might not be in the local
1241 list. Fixed a bug related to LEAVE command.
1243 * Is this the end of the [<unknown>] buglet that has been lurking
1244 around for a long time? A little for loop fix in server's
1245 silc_server_command_whois_parse that is used by both IDENTIFY
1246 and WHOIS command. At least, this was a clear bug and a cause
1247 of one type of [<unknown>] buglet.
1249 * WHOIS and IDENTIFY commands call the function
1250 silc_server_command_[whois/identify]_check function even if
1251 we are not router server.
1253 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Added --with-gmp configuration option. If set the GMP
1256 is always compiled in the SILC source tree. If not set then
1257 it is checked whether the system has the GMP3 installed. If
1258 it has then the GMP won't be compiled (the system's headers
1259 and library is used), if it doesn't have it then the GMP is
1260 compiled in the SILC source tree.
1262 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Changed RSA private exponent generation to what PKCS #1
1265 suggests. We try to find the smallest possible d by doing
1266 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1267 not security fix but optimization.
1269 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added new config entry [Identity] to fork the server and run
1272 it as specific user and group. A patch from Bostik.
1274 * Imported Dotconf configuration library into lib/dotconf.
1275 This will be used to create the SILC configuration files later.
1276 It will appear in the distsribution after this commit.
1278 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * A big code auditing weekend happening. Auditing code for
1281 obvious mistakes, bugs and errors. Also, removing any code
1284 Removed files for being obsolete:
1286 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1287 inline in the file lib/silcutil/silcbuffer.h)
1289 o lib/silcutil/silcbufutil.c (the header has inline versions)
1291 Changed code to fix possible error conditions:
1293 o The buffer formatting routines now check that the destination
1294 buffer really has enough space to add the data. This applies for
1295 both buffer formatting and unformatting
1296 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1297 unformatting was changed to accomodate following rules:
1298 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1299 sent to the function while XXX_*STRING will not allocate or copy
1300 the data into the buffer. Instead it sets the pointer from the
1301 buffer into the pointer sent as argument (XXX_*STRING used to
1302 require that the pointer must be allocated already). This change
1303 makes this whole thing a bit more consistent and more optimized
1304 (note that the data returned in the unformatting with XXX_*STRING
1305 must not be freed now). The routines return now -1 on error.
1307 o Tried to find all code that use buffer_format and buffer_unformat
1308 and added return value checking to prevent formatting and
1309 especially unformatting errors and possible subsequent fatal
1312 o Changed ske->x and ske->KEY to mallocated pointers in
1313 lib/silcske/silcske.h. Fixed possible data and memory leak.
1315 o Added return value checking to all *_parse* functions. Fixed
1316 many memory leaks as well.
1318 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1319 so that buffer overflows would not happen. All code now also
1320 checks the return value as it can fail.
1322 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Added reconnection support to server if the normal server looses
1325 its connection to the router (for example if router is rebooted).
1326 The server performs normal reconnection strategy implemented
1327 to the server. Affected file silcd/server.c.
1329 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1331 * Added new packet type SILC_PACKET_SET_MODE that is used to
1332 distribute the information about changed modes (for clients,
1333 channels and clients channel modes) to all routers in the
1334 network. Updated the protocol specification accordingly.
1336 Added functions into silcd/packet_send.c and
1337 silcd/packet_receive.c: silc_server_send_set_mode,
1338 silc_server_set_mode.
1340 Added new files silcmode.[ch] into lib/silccore that implements
1341 the encoding and decoding of Set Mode Payload. Added new type
1342 SilcSetModePayload. Moved the definitions of different modes
1343 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1345 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Oops, a little mistake in server's connection authentication
1348 protocol. The protocol is not ended with FAILURE but with
1349 SUCCESS if the authentication is Ok. :) Affected file is
1352 * Implemented NICK_CHANGE notify handling in server in the file
1353 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1354 the local clients on the channel. After the changing nickname
1355 in router environment snhould work and the [<unknown>] nickname
1356 should appear no more.
1358 The silc_server_replace_id function that receives the Replace ID
1359 payload now sends the NICK_CHANGE notify type also in the file
1360 silcd/packet_receive.c
1362 * Changed WHOIS and IDENTIFY command to support the maximum amount
1363 of arguments defined in protocol specs (3328 arguments). This
1364 fixed a bug that caused problems when there were more than three
1367 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Added extra parameter, command identifier, to the
1370 silc_client_send_command so that explicit command identifier
1373 Changed that ID list routines uses specific command identifier
1374 when sending WHOIS/IDENTIFY requests to the server so that they
1375 can be identified when the reply comes back.
1377 Affected files lib/silcclient/command.[ch],
1378 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1380 * Added `sender' argument to silc_server_packet_send_to_channel
1381 to indicaet the sender who originally sent the packet to us
1382 that we are now re-sending. Ignored if NULL. Affected file
1383 silcd/packet_send.[ch].
1385 * Added some server statistics support in silcd/server_internal.h
1386 SilcServerStatistics structure and around the server code. Also
1387 send some nice statistics information when client is connecting
1390 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Fixed channel ID decoding in server's JOIN command reply in
1393 silcd/command_reply.c
1395 * Fixed braodcasting of replace ID payload to not to send it if
1396 we are standalone server in silcd/packet_receive.c.
1398 * Fixed all channel message sending routines to not to send
1399 packets to clients that has router set, since they are routed
1400 separately in the same function earlier. Affects file
1401 silcd/packet_send.c and all channel packet sending functions.
1403 * In USERS reply, res_argv[i] are not allocated, the table
1404 is allocated. Thus changed that free the table, not its
1407 * In server's whois_check and identify_check if the client is
1408 locally connected do not send any WHOIS commands - they are not
1411 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Fixed some minor bugs in client when sending WHOIS command. The
1414 arguments was in wrong order.
1416 * Removed statis function add_to_channel from server in
1417 silcd/command.c that was previously used with the joining but
1420 * Tested USERS command in router environment successfully with two
1421 routers, two servers and two clients.
1423 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Reorganized the USERS command and command reply in client library
1426 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1427 When the command is given by user we register a pending command
1428 callback that will reprocess the command after the reply has been
1429 received from the server. When reprocessing the packet we then
1430 display the information. Thus, the USERS information is displayed
1431 now in the command callback instead of in the command reply
1432 callback. The processing of the command is same as previously
1433 when server has sent the command reply in the JOINing process.
1435 * Added to USERS command in silcd/command_reply.c to join the client,
1436 we didn't use to know about, to the channel after we've created
1437 a client entry for it. Also, for clienet we did know already still
1438 check whether it is on the channel or not and add it if not.
1440 * Removed silc_server_command_join_notify as the function and its
1443 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Changed the client's pending command handling to the same as the
1446 server's pending command handling. It is also now possible to
1447 execute command reply functions from other command reply
1448 function as the function callbacks for commands and command
1449 replies are one and same. The pending commands are not static
1450 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1451 in client connection context. Thus, pending commands are server
1452 connection specific as it is convenient.
1454 Changed the function silc_client_command_pending and
1455 silc_client_command_pending_del and added new function
1456 silc_client_command_pending_check. Removed the
1457 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1460 * Added cmd_ident, current command identifier, to the client
1461 connection context in lib/silcclient/client.h to keep track on
1462 command identifiers used in command sending. Client's command reply
1463 function handling now supports the mandatory command identifiers.
1465 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1466 funtions in client to fully support pending command callbacks.
1468 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1469 as one of the arguments to the application in the command reply
1472 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1473 before first releasing SILC but came back. Now it is removed again
1474 and should come back nomore. The FORWARDED flag was used only
1475 by the JOINing procedure by forwarding the command packet to router.
1476 Now, the JOINing procedure has been changed to more generic (due
1477 to various router environment issues) and FORWARDED is not needed
1478 anymore for anything. The protocol specification is yet to be
1481 Now, removed silc_server_packet_forward from server and the flag
1482 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1484 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Renamed NAMES command to USERS command. The NAMES was named that
1487 due to historical reasons. Now it is renamed. Also, rewrote
1488 parts of the USERS command. The nickname list is not sent anymore
1489 by the server. Only Client ID and mode lists are sent in the USERS
1490 command. Changed this also to the protocol specification.
1492 The client now resolves the names and stuff after it receives
1493 the USERS list from the server when joining to the channel.
1495 * WHOIS and IDENTIFY commands has been changed to support multiple
1496 Client ID's per command. One can now search for multiple users
1497 in the network by sending only one WHOIS or IDENTIFY command.
1498 Changed the code and the protocol specifications.
1500 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1501 uses silc_server_command_whois_parse to parse the request. */
1503 * If normal server, do not parse the WHOIS and IDENTIFY requests
1504 before sending it to the router. Saves some time.
1506 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Fixed JOIN command on client library. Wrong number of arguments
1509 used to crash the client.
1511 * Added silc_server_channel_has_global function to check whether
1512 channel has global users or not.
1514 * Added silc_server_channel_has_local function to check whether channel
1515 has locally connected clients on the channel.
1517 * The silc_server_remove_from_one_channel now checks whether the
1518 channel has global users or not after given client was removed from
1519 the channel. It also checks whether the channel has local clients
1520 on the channel anymore. If it does not have then the channel entry
1521 is removed as it is not needed anymore.
1523 * The silc_server_notify now checks on JOIN notify whether the joining
1524 client is one of locally connected or global. If it is global then
1525 the channel has now global users on the channel and that is marked
1526 to the channel entry. Also, it now saves the global client to
1527 global list who is joining and JOINs it to the channel. This is
1528 for normal server, that is.
1530 Changed silc_server_send_notify_on_channel,
1531 silc_server_packet_relay_to_channel and
1532 silc_server_packet_send_to_channel check if we are normal server
1533 and client has router set (ie. global client) do not send the
1534 message to that client, as it is already routed to our router.
1536 * Implemented LEAVE notify type handling in silc_server_notify
1539 * Tested LEAVE command in router environment successfully. Tested
1540 with two routers, two servers and two clients.
1544 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1546 * Implemented SIGNOFF notify type handling in silc_server_notify
1549 * silc_server_remove_id now removes the client entry from all channels
1550 it has joined and thusly sends SIGNOFF notify type.
1552 * Rewrote the NAMES list generation in server by removing two excess
1553 loops. The lists are created now inside one loop.
1555 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * silc_server_remove_channel_user checks now also global list
1558 for channel and client.
1560 * silc_server_new_channel_user checks now both local and global
1561 list for channel and client. Fixed a bug in client id decoding.
1562 Used to decode wrong buffer.
1564 * silc_server_channel_message checks now both local and global
1565 list for channel entry.
1567 * Tested channel joining (hence JOIN) in router environment
1568 successfully. Tested with two routers, two servers and two
1571 * Tested channel message sending in router environment successfully.
1573 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1575 * Added silc_server_save_channel_key into server.[ch] to save the
1576 received channel key in Channel Key payload processing. It is
1577 also used in JOIN command reply handling.
1579 Equivalent function silc_client_save_channel_key added into
1580 client.[ch] into client library.
1582 * Changed JOIN command reply to send information whether the channel
1583 was created or not (is existing already) and the channel key
1584 payload. Changed protocol specs accordingly.
1586 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1587 the request was sent by ID and not by nickname. Crashed on
1590 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1593 now correctly save the received data.
1595 * silc_server_free_sock_user_data now notifies routers in the
1596 network about entities leaving the network.
1598 At the same time implemented functions silc_server_remove_id
1599 and silc_server_send_remove_id to receive and send REMOVE_ID
1600 packets. The packet is used to notify routers in the network
1601 about leaving entities. The ID removed will become invalid in
1604 * Added function silc_idlist_del_server into server. Removes and
1605 free's server entry from ID list.
1607 * silc_server_private_message function now checks, if we are router,
1608 that the destination ID really is valid ID, naturally.
1610 * In router when NEW_ID packet is received (for new client) the
1611 hash of the Client ID is saved in the ID Cache but the
1612 client->nickname is set to NULL, instead of putting the hash
1615 IDENTIFY command now also checks that client->nickname must be
1616 valid. If it is not if will request the data from the server who
1617 owns the client. Added new function
1618 silc_server_command_identify_check.
1620 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1621 to set the command to already allocated Command Payload.
1623 * Tested private message sending in router environment with two
1624 routers, two servers and two clients. Fixed minor bugs and now
1627 * Fixed segfault from client's NAMES command. Used to crash if
1630 * Forwarded packets must not be routed even if it is not destined
1631 to the receiver. Changed server code comply with this.
1633 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Added `require_reverse_mapping' boolean value to ServerParams
1636 structure. If TRUE (not default) the server will require that
1637 the connecting host has fully qualified domain name.
1639 If the reverse mapping is not required and hostname could not be
1640 found the IP address is used as hostname.
1642 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Implemented version string checking to both client and server.
1645 The check is incomplete currently due to the abnormal version
1646 strings used in development version of SILC.
1648 * Changed all command functions in server to use the new
1651 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Changed char *data to unsigned char *data in ID Cache system to
1654 support binary data as ID Cache data. Changed code to support
1655 binary data in lib/silccore/idcache.c.
1657 * Renamed silc_server_packet_relay_command_reply to
1658 silc_server_command_reply as it is normal packet receiving
1659 function. Rewrote the function to accept command replys for
1660 servers and not only for clients.
1662 * Mark remote router always as registered server if we are connecting
1663 to it. Otherwise, commands sent by the router to us are ignored.
1665 * All ID List find routines now returns the ID Cache Entry pointer
1666 as well if requested.
1668 * WHOIS command works now in router environment, tested with two
1669 routers, two servers and two clients.
1671 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1672 in router environment (as it is almost equivalent to WHOIS) but
1673 hasn't been tested thoroughly. Added new functions:
1675 silc_server_command_identify_parse
1676 silc_server_command_identify_send_reply
1677 silc_server_command_identify_from_client
1678 silc_server_command_identify_from_server
1680 * Disabled route cache adding because adding two different ID's with
1681 same IP replaces the old cache entry thus giving wrong route.
1682 The entry->router->connection is always the fastest route anyway
1683 so route cache may not be needed. Of course, new routes maybe
1684 established after receiving the ID when the entry->router->connection
1685 might not be anymore the most optimal.
1687 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Add route cache for received ID for fast routing.
1691 * Added silc_server_packet_route to route received packet on router
1692 that is not destined to us.
1694 * Renamed silc_server_get_route to silc_server_route_get.
1696 * Added id_string and id_string_len fields into SilcServer to
1697 include encoded ServerID for fast comparing without excess
1698 encoding of the ID's.
1700 * Cleaned up WHOIS command on server side. Added following static
1703 silc_server_command_whois_parse
1704 silc_server_command_whois_check
1705 silc_server_command_whois_send_reply
1706 silc_server_command_whois_from_client
1707 silc_server_command_whois_from_server
1709 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1710 arguments in command replies. All command functions should be
1711 updated to use this macro.
1713 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Minor typo fixes on command reply handling on server.
1717 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Added silc_server_command_add_to_channel internal routine to add
1720 the client to the channel after router has created the channel and
1721 sent command reply to the server.
1723 * Added generic silc_server_send_command to send any command from
1726 * Use static buffer with ID rendering instead of duplicating data.
1728 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Fixed a channel user mode bug when joining to a channel server gave
1731 everybody channel founder rights, oops.
1733 * We mark ourselves as the router of the incoming server connection
1734 if we are router ourselves. This way we can check in some packet
1735 sending functions whether it is locally connected server. For
1736 incoming router connections we put NULL.
1738 * For router sending packets locally means now always sending the
1739 packet cell wide; to local clients and local servers. For normal
1740 server sending packet locally means sending it to only local
1743 * Fixed the JOIN command to really work in router environment. If the
1744 channel is created it is always created by the router. Router is
1745 also responsible of making the initial joining to the channel,
1746 sending JOIN notify to the sending server and distributing
1747 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1748 does not exist server doesn't do anything else but forward the
1749 command to the router which performs everything.
1751 * Added silc_server_send_channel_key function to send the Channel Key
1754 * Added silc_server_create_channel_key to create new channel key. The
1755 channel key is now re-generated everytime someone joins or leaves
1756 a channel, as protocol dictates. Note: channel->key_len is the
1759 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1761 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1762 packet_receive.[ch] to separate packet sending and receiving
1763 routines. The server.[ch] now includes everything else including
1764 actual packet processing (writing and reading data) and other
1767 Renamed silc_server_private_message_send_internal to
1768 silc_server_send_private_message. The routine is still though
1769 used only to relay private messages as server does not send
1770 private messages itself.
1772 Renamed silc_server_new_channel to silc_server_create_new_channel
1773 and added new function sicl_server_new_channel that handles the
1774 incoming New Channel packet. Added also new sending function
1775 silc_server_send_new_channel to send New Channel Payload.
1777 * Added new function silc_server_notify to process incoming notify
1778 packet to the server/router. Server may then relay the notify
1779 to clients if needed.
1781 * Added new function silc_server_new_channel_user to process incoming
1782 New Channel User packet. Router will redistribute the packet and
1783 send JOIN notify to its local clients and locally connected servers
1784 if needed. Normal server will send JOIN notify to its local client
1785 on same channel when received this packet. Added also corresponding
1786 sending function silc_server_send_new_channel_user to sent the
1789 * Added boolean route argument to send_notif_to_channel and
1790 packet_send_to_channel functions to attempt to route the packet
1791 if it is TRUE and send only locally if it is FALSE.
1793 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * silc_server_replace_id now broadcasts the received replace ID
1796 packet if it is not broadcast packet already. The router must
1797 broadcast to inform other routers about changed ID.
1799 * Added backpointer to server's router into SilcServer context in
1800 silcd/server_internal.h.
1802 * Fixed silc_server_packet_broadcast to send correct broadcast
1805 * The channel key is now distributed to the local client as soon
1806 as it is received from the router (in router environment) so that
1807 no other packet may be sent for the channel until client has
1810 * silc_server_remove_channel_user now broadcasts the received
1811 Remove Channel User packet if it is not broadcast packet already.
1812 The router must broadcast to inform other routers about removed
1815 * Added users field into SilcPacketContext that is a reference count
1816 of the context. One can increase the reference count by calling
1817 silc_packet_context_dup which is now changed to just increase the
1818 reference count instead of duplicating the data. The reference
1819 count is decresed by calling silc_packet_context_free that will
1820 free the data after the reference count hits zero.
1822 For now on the packet context and everything allocated into it
1823 (including the raw packet from network) must be freed by calling
1824 the new silc_packet_context_free function. Added also new function
1825 silc_packet_context_alloc that must be used now to allocate the
1826 context. This also means that if a routine is asynchronous from
1827 silc_[client/server]_packet_parse_type the packet context must
1828 be duplicated by calling silc_packet_context_dup. Otherwise it
1829 gets free'd after silc_[client/server]_packet_parse_type returns.
1830 Also, one must remember that if packet is duplicated then its
1831 reference count must be decresed by calling the free function as
1832 many times as it was duplicated.
1834 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1835 from both client and server.
1837 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Made joining to a channel working in router environment.
1841 * Cleaned up JOIN command on server side and create function
1842 silc_server_command_join_channel internal routine to make the
1845 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * Changed silc_command_pending list to SilcDList. Also, added
1848 `ident' field to SilcServerCommandPending structure to identify
1849 the reply and to call correct callback.
1851 Added silc_server_command_pending_check function to replace the
1852 corresnponding macro. The silc_command_pending list is not
1855 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1856 to set identifier to previously allocated Command Payload. It
1857 is used to set identifier for command when resending Command
1860 * Added silc_command_payload_encode_payload to encode Command
1861 Payload buffer from SilcCommandPayload structure.
1863 * Added silc_argument_payload_encode_payload to encode Argument
1864 payload buffer from SilcArgumentPayload structure.
1866 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1868 * Changed WHOIS command to support router connection on server side.
1869 The whois request is always sent to router unless the server is
1870 standalone server. After server has received the reply from the
1871 router will it send the reply to the client.
1873 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1874 broadcast received broadcast packet. The function is used only
1875 by router. The broadcast packet is always sent to the router's
1878 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1879 render given ID to printable string, for log files for example.
1881 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Made basic router to router connections working. At least they
1884 can now connect to each other but nothing really works the way
1885 they are supposed - yet.
1887 * Added new initiator token to RouterConnection configuration
1888 file in silcd/serverconfig.[ch]. It is used to tell whether we
1889 are the initiator to the remote router or whether we'll expect
1890 the other end to connect.
1892 * Moved registering of listener task to silc_server_init, hence
1893 the server starts listenning as soon as it is run, even if it
1894 does not have connections to other routers. Let's see how well
1897 * Changed default connection retry timeouts for more suitable in
1900 * Removed cipher and such arguments from silc_idlist_add_client
1901 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1902 Added new function silc_idlist_add_data to add the keys and stuff
1905 * Added SilcIDListData structure and added it to SilcClientEntry
1906 and SilcServerEntry as their first field in the structure. This
1907 way we can explicitly cast the ID entries to the SilcIDListData
1908 structure and get common data for the entries. In past, we had
1909 to first check what type of connection it is and then cast it to
1910 correct ID entry type. Now, we can directly cast the opaque
1911 pointer to the SilcIDListData (no matter what ID entry it actually
1912 is) and get the data needed.
1914 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1917 in some circumstances even if threre were timeout tasks, though not
1918 IO tasks, but tasks anyway. Now fixed.
1920 * Defined SilcServerConnection structure to hold connection specific
1921 stuff about directly connected servers and routers. The definition
1922 is currently in silcd/server_internal.h. I thought about having
1923 a bit more important role fro this struct but for now it is used
1924 only when connecting to other server (or router actually).
1926 * Added connecting retry support in server when connecting to
1927 router(s). The retry feature implement exponential backoff
1928 algorithm. Also, added SilcServerParams structure to hold default
1929 parameters for server. For now, it include these retry settings
1930 and are hard coded. After server is moded to be as Silc Server
1931 Library this structure will be more important.
1933 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Changed client librarys channel->clients table to SilcList and
1936 changed code accordingly.
1938 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Changed client's channel table to SilcList and changed code
1941 accordingly. Also changed SilcChannelClientEntry to include back-
1942 pointer to the channel so that client entry can use that structure
1943 as list as well and we have fast cross-reference to the channel.
1944 This change dramatically decreased the complexity of channel
1945 handling with client entry and vice versa (removed one extra
1946 loop when searching for channel entry from many functions).
1948 * Changed server->sim from table to SilcDList and changed code
1951 * NAMES command can now be used from user interface. It will show
1952 the user list on the channel, neatly.
1954 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1955 Code now saves realname of the user if it becomes available.
1957 * Renamed configure.in to configure.in.pre and made ./prepare
1958 script to automatically add correct version string to
1959 configure.in which it creates from configure.in.pre.
1961 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * NAMES command reply now shows users mode with the nickname when
1966 * Moved silc_client_ch[u]mode[_char] functions from
1967 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1968 place sucks, they are utility functions and should be in some
1971 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1973 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1976 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Added TRQ (efficient deque and list library) into lib/trq. This is
1981 a very good list library that is currently used in the SILC. Defined
1982 SilcList API over the library because I didn't like the API very
1983 much. See lib/trq/silclist.h for the API and examples of how to
1984 use the API. Fixed various places in the code to use the new
1985 SilcList API. The SilcList is meant for lists that has a structure
1986 already defined as a list. It is not suitable to add just some
1987 context to the list (in TRQ, the context is the list actually).
1989 So, I defined SilcDList that can be used for the purpose where
1990 predefined list structure does not exit. This can be used as
1991 such list. Now some context just can be added to the SilcDList.
1992 Currently this list is not used in the SILC just yet, though there
1993 are a lot places where this can replace dynamically allocated
1994 tables and I will fix these places, later, to use SilcDList.
1995 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1996 and use TRQ internally).
1998 Also fixed some annoying warning messages that the original TRQ
1999 code generated. Also minor changes to TRQ's Makefile.in.
2001 * Added support for querying by Client ID to both WHOIS and
2002 IDENTIFY commands into server, as required by the protocol.
2004 * Removed method function pointers from SilcBuffer structure. They
2005 weren't used to anything and just increased the context size for
2006 no good reason. This change also made silc_buffer_alloc and
2007 silc_buffer_free functions inline functions.
2009 * Disabled command flooding detection support until it's fixed so
2010 that it accepts commands in but does not execute them more than once
2013 * Added silc_net_localhost(), to return local hostname, into
2014 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2015 that must be initialized before calling silc_client_init.
2017 * Added new function: silc_server_send_notify_on_channels to send
2018 notify messages to all channels client has joined. It is assured
2019 that the message is sent only once per client.
2021 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2022 lib/silcutil/silcutil.[ch] as silc_format function. The new
2023 function is generic and is used by server as well, not only by
2024 the logging routines.
2026 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2027 the provided version string was not acceptable. Added new function:
2028 silc_ske_check_version into lib/silcske/silcske.h. The function
2029 must be implemented by the application (client or server) and it
2030 does not reside in the SKE library. The function checks the version
2031 string remote end sent.
2033 * Added back pointers (to opaque context and to SilcSocketConnection)
2034 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2036 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2037 duplicate packet context structure.
2039 * Changed `notify' client operation to send same arguments as client
2040 receives from server except for ID's. ID's are mapped to correct
2041 ID entry and that is returned. Also, if channel entry is not sent
2042 by server but the notify is for channel the channel entry is sent
2043 to application (otherwise application doesn't know that it is for
2044 channel (library gets it from packet's Destination ID)).
2046 * Added silc_client_remove_from_channels into client library to
2047 remove a client from all channels it has joined to. Used when
2048 received SIGNOFF notify from server. Added also new function
2049 silc_client_replace_from_channels to replace old ID entry with
2050 new ID entry on all channels. Used when received NICK_CHANGE
2053 * Fixed ID Cache list handling in silc_idlist_get_client in
2054 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2055 to get (or query) client by ID.
2057 * Updated TODO list.
2059 * Added connection authentication status message defined by the
2060 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2061 support for these into the code in client and server side.
2063 * Added generic function silc_client_send_command to send any command
2064 with variable argument list. Application should use this function
2065 to send commands if the command functions provided by the library
2066 does not suite for the application's user interface needs.
2068 * Added new `failure' client operation. Application is notified about
2069 received failure packet if client is executing a protocol. In this
2070 case the protocol's execution has failed.
2072 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2073 is required by the protocol.
2075 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2076 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2079 * Added status flag to SilcSKE object to indicate realtime status
2080 of the SKE protocol.
2082 * Application receives now exactly same command reply arguments as
2083 the library receives from server. However, if ID is received the
2084 corresponding ID entry is returned to the application (eg. Client
2085 ID is mapped to correct SilcClientEntry entry and that is returned).
2086 Changed command_reply client operation due to this change.
2088 * Changed all ID's in commands and in command replys as ID Payloads.
2089 Change affected both client and server side codes.
2091 All ID's sent in SILC network (with execption of ID's in SILC
2092 Packet header) are sent in ID Payload to support variable length
2095 * Server now notifies nick changes and notifies all clients on
2096 the channels about the new nickname (about the new Client ID,
2099 * Implemented CMODE command to change channel modes. Supports all
2100 channel modes defined by the protocol specs except ban and invite
2101 lists. (Also, private channel key mode is supported but support for
2102 setting private channel key in client is missing, thus, this mode
2103 has no effect on client side (except that server requires that the
2104 client uses private channel key and normal channel traffic does not
2107 Also, invite mode works per se, but INVITE command does not work
2108 yet correctly, so you can set channel as invite only channel but
2109 inviting clients to the channel does not work (it is yet to be
2110 thought what's the best way to do it).
2112 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2113 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2114 Implemented CUMODE command to change user's mode on the channel.
2115 Supports all modes defined by the protocol specs.
2117 * Added NAMES command reply to return users modes on the channel.
2119 * Removed unnecessary and slow ciphers from lib/silccrypt.
2121 * Set SO_KEEPALIVE option to connection sockets by default.
2123 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2125 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2126 redefined the Notify Payload into protocol specs.
2128 * Added silc_id_payload_parse_id to get ID directly from raw
2131 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2134 accept searching by Client ID as well.
2136 * Added support for LEAVE and SIGNOFF notify types in client library.
2138 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2139 to parse ID Payload from raw data.
2141 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added flags parameter into silc_ske_assemble_security_properties
2144 function in lib/silcske/silcske.[ch].
2146 * Changed notify client operation to fit better for notify messages
2147 sent by server. The notify payload received from server is now
2148 passed to the application (after parsing it to SilcNotifyPayload).
2149 It is application's responsibility to retrieve the arguments
2150 from the payload and show the message the way it wants. The message
2151 sent by server is implementation specific.
2153 * Changed public keys to comply with the protocol specification.
2154 Old public keys are not supported anymore and are not compatible.
2156 * Removed nickname from Channel Payload as the latest draft removed
2157 it. The client must resolve the nickname from the NAMES command
2158 reply received when it joined the channel.
2160 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2162 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Fixed some errors in protocol specification drafts.
2166 * Created lib/silccore/silcnotify.c to implement Notify Payload
2167 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2168 generic payloads described by protocol specifications. The file
2169 includes implementations for ID Payload and Argument Payload.
2171 * Changed Command Payload implementation to use the new Argument
2172 Payload. Changed command_xxxx_payload to command_payload_xxxx
2173 to comply with SILC coding conventions.
2175 * Added suppport for Argument Payload handling in Notify Payload
2176 implementation as protocol requires it. Added the new support
2177 into server and client lib as well.
2179 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2181 * Added support for multiple nicknames on same channel. [n] is
2182 added locally to the nickname if there are more than one same
2183 nicknames on the channel.
2185 * Server now sends all nicknames that matched WHOIS request.
2186 Client also shows the list received from server.
2188 * Added TOPIC command to client side. User can now set and show
2189 current topic on channel.
2191 * Added MOTD command to client and server. Also, server sends the
2192 motd when client connects to the server.
2194 * Changed version strings to comply ISO 8601.
2196 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Fixed protocol error handling in client library. It should now
2199 cope even if the SKE fails for some reason.
2201 * Made new protocol specification drafts for submitting to IETF.
2203 * Implemented TOPIC command to server in silcd/command.c.
2205 * Added two new notify types into lib/silccore/silcnotify.h:
2206 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2207 notify nickname change and topic setting/change on a channel.
2209 * API change of command_reply operation in client library. The
2210 application gets now the status type received from server as well.
2212 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2216 * Cras fixed and optimized the packet handling even further and
2217 it should work now. Minor change to the prototype of function
2218 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2220 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Added new function into lib/silcutil/silcschedule.[ch]:
2223 silc_schedule_with_fd to select() a specified fd. The function
2224 returns after timeout expires or data arrives or goes. The
2225 function is used by packet routines to wait that all data is
2226 received from network.
2228 * Fixed data reading from network in lib/silccore/silcpacket.c.
2229 The code now assures that all data is read from the fd and then
2230 continues packet processing. This was a bug fix since the code
2231 used to drop some data in some circumstances.
2233 * Added new function into lib/silcclient/client.[ch]:
2234 silc_client_start_key_exchange to start key exchange after
2235 connection has been established to server. The code internally
2236 now uses this funtion but its main purpose was to provide it
2237 for applications that perform their own connecting. After
2238 application has created a connection it merely calls this
2239 function to start the key exchange between client and server.
2240 The library takes care of everything else after that.
2242 Updated also lib/silcclient/README to explain the usage of
2245 * Do not send to application information that connection has
2246 been established. Application gets notified it by connect
2249 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Applied cras's patch to add silc_schedule_one function. The
2252 function runs scheduler once and returns.
2254 * Fixed the scheduler after cras messed it up. The timeout
2255 handling works now as it's supposed to work.
2257 * Added into lib/silccore/ silcnotify.h to include notify
2258 message types support. Changed silc_server_send_notify*
2259 functions, in server.[ch], to support those new notify types.
2260 Added the support for the notify types into client library,
2261 as well. Added new notify client operation into ops.h in
2264 * Changed silc_server_packet_send_to_channel to send normal
2265 packets instead of just channel message packets. The function
2266 is now used to send the notify packets to channels. It is not
2267 used to send channel message packets anymore, as server never
2270 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2271 va_arg()s as it seems to require it nowadays. I guess, if SILC
2272 is compiled with older va_arg() the new code should work anyway.
2274 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Splitted core library. Core library (lib/silccore) includes
2277 now only SILC protocol specific core (and common) components.
2278 Created new utility library (lib/silcutil) that includes more
2279 generic purpose stuff. The stuff for util library was taken
2280 from the old core library. This was minor and easy split.
2282 * Created SILC Client Library (lib/silcclient) that includes
2283 implementation of the SILC client without user interface. This
2284 was major move from silc/ directory. The code has been changed
2285 so that it is transparent towards the user interface. The
2286 silc/ directory includes now the same user interface as before
2287 and it uses the new client library. Read lib/silcclient/README.
2288 Basicly, the client library performs everything else related
2289 to SILC except user interface handling. Also, configuration
2290 files are considered to be part of user interface and library
2291 does not handle them.
2293 This change also changed a lot of structures, function naming etc.
2294 Most important change was that SilcClientWindow object was
2295 renamed to SilcClientConnection in the client library. Created
2296 also new file lib/silcclient/ops.h. Also added new files
2297 silc/local_command.[ch] and silc/client_ops.[ch].
2299 All these changes were made to make it easier for user interface
2300 designers to create what ever user interface for the SILC client
2303 It is also expected that the server will be moved to lib
2304 directory as well and SILC Server Library will be created;
2305 sometimes in the future.
2307 * Removed Local commands from lib/silccore/silccommand.h as
2308 they are application specific and new client library does not
2309 handle any of those anymore.
2311 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2312 old client implementation in silc/.
2314 * Added support for callback functions in SILC_LOG_* macros.
2315 Application can now set its own callbacks that will be called
2316 instead of using the default functions that will always print
2317 the debug messages to stderr (or stdout). Also, debugging can
2318 now be disabled by setting silc_debug to FALSE and re-enabled by
2319 setting it to TRUE. Note, that logging will still work even
2320 if debugging is disabled.
2322 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2323 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2324 silc_log_reset_debug_callbacks.
2326 * To enable debugging in silc client one must give now -d
2327 option on command line.
2329 * Changed silc_schedule_init to automatically allocate task queues
2330 if they are not allocated before calling it.
2332 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Added GMP 3.1 into math library.
2336 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2339 a channel in SILC network. The packet is used by servers and
2340 routers to notify other routers that user has left a channel.
2341 This little feature was missing until now. Added the feature
2342 to protocol specification as well.
2344 Added functions: silc_server_send_remove_channel_user and
2345 silc_server_remove_channel_user into server.[ch].
2347 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2348 lib/silccore/silcpacket.h. However, they are not implemented
2351 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Fixed joining to a channel and sending channel messages
2354 between server and router. The channel message sending should
2355 now work inside a cell.
2357 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Fixed the private message sending between server and router.
2360 The private message sending should now work inside a cell.
2362 * Added silc_server_replace_id into server.[ch] to replace
2363 existing ID in the SILC network.
2365 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2366 and silc_idlist_replace_server_id into idlist.[ch] in server.
2368 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed the server to server connections. Server can again now
2371 connect to router. Router to router connections probably does
2374 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Added dynamic protocol registering support. Now protocols can
2377 registered and unregistered on the fly. Patch by cras.
2379 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Added lib/contrib directory to hold routines that some platforms
2382 don't have but are needed by SILC.
2384 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2385 into lin/contrib to provide getopt() and getopt_long() for
2386 those who don't have it.
2388 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Added AWAY command to client. When away message is set and
2391 client receives a private message packet the client automatically
2392 replies to the sender with the away message.
2394 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2395 bug seemed to be the cause of recent problems when compiling
2398 * Added version detection support to SKE protocol specification
2399 and added the new changes to the SKE implementation as well.
2400 There were other minor changes in the SKE protocol as well.
2402 Many changes in lib/silcske/silcske.[ch] and in
2403 lib/silcske/payload.[ch].
2405 * Added ^U functionality, clear input line. Patch from cras.
2407 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Mainly small bugfixes on core library. Fixed some debugging
2410 logging and buffer overflow in silclog.c.
2412 * Updated config.sub and config.guess on the distribution tree.
2414 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added command lagging support in server. Client may execute
2417 commands now only once in two seconds.
2419 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Optimized packet reception. MAC computation and checking is now
2422 also more optimized. A lot previously duplicated code is now
2423 used as generic by both client and server.
2425 * Fixed key pair generation in clientutil.c
2427 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Added into lib/silccore/silcbufutil.[ch] new function;
2430 silc_buffer_realloc.
2432 * Moved generic packet sending/encryption functions to
2433 lib/silccore/silcpacket.[ch] from client and server. Some
2434 rewriting of the functions.
2436 * Moved all generic packet reception/decryption functions to
2437 lib/silccore/silcpacket.[ch] from client and server. The
2438 packet processing is now much cleaner in both client and server.
2439 These were major changes in both client and server.
2441 * Created many common functions in server to do packet sending.
2442 Previously code were duplicated a lot, this has been removed
2445 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Rewrote major parts of the ID cache system. Don't know
2448 whether it is better now or not but at least the API is more
2451 * Major rewrite on ID cache stuff on client because of the ID
2452 cache API changes. Added idlist.c to client.
2454 * Also major rewrite on ID cache stuff on server as well.
2455 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2456 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2457 in hand, instead they are all put into the ID cache system now.
2458 All server_idlist_* routines uses ID cache now instead of
2459 traversing its own lists (those lists does not exist anymore).
2460 SilcIDList though still exists. Also, SilcXXXEntry's are
2463 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Finally made the SKE implementation compliant to the protocol
2466 specification. All mp integers are now binary encoded as
2467 opposed being HEX encoded.
2469 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2472 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2473 functions: silc_[encode/decode]_pem. Also added function
2474 silc_encode_pem_file to PEM encode with newlines ('\n') for
2477 * SILC public keys are now encoded either PEM or binary. Same
2478 option is for private keys as well. By default private keys
2479 are binary encoded and public keys PEM encoded. Silly HEX
2480 encoding were removed.
2482 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2483 function to create fingerprints.
2485 * Fixed a bug in SHA1; does not change the original data anymore.
2487 * Partly implemented INFO command on client and server side.
2488 Fixed CLEAR command. Changes to SERVER command; show current
2489 server(s) when giving command without arguments. Added
2490 VERSION command to client.
2492 * Added check to server that unregistered connections cannot
2493 execute commands (unless it is specificly allowed).
2495 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Fixed screen refresh.
2499 * Fixed channel joining bug from client. On some circumstances
2500 client tried to join to a channel it had already joined.
2502 * Added public key verification process into client's protocol.c.
2503 The client now verifies the public key from user and saves
2504 it into ~./silc/serverkeys/ directory.
2506 Added into: clientutil.[ch]: silc_client_verify_server_key.
2508 * Changed SKE protocol's silc_ske_initiator_finish function
2509 to accept callback function that verifies the received public
2510 key. Removed old silc_ske_verify_public_key function.
2512 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2515 silc_pkcs_private_key[_data]_set.
2517 * Made the password and public authentication more cleaner in
2518 server's protocol.c.
2520 * Removed historic and obsolete protocol `channel_auth' from
2521 both client and server.
2523 * Removed wrong way of sending command status messages from
2524 server to client in server's command.c. The old way violated
2525 protocol specification.
2527 Changes to silccore/silccommand.[ch]: removed
2528 silc_command_encode_status_payload -> not needed anymore,
2529 changed silc_command_encode_payload_va to accept extra
2530 argument on variable argument list. The argument type must
2531 now be provided to the function. Also, added new function:
2532 silc_command_encode_reply_payload_va which is same as
2533 normal command_encode_payload_va except command status type
2534 is provided as extra argument.
2536 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Added ~./silc directory handling. The directory includes the
2539 public and private keys for the client.
2541 Added silc_client_check_silc_dir, silc_client_create_identifier
2542 and silc_client_load_keys.
2544 * Implemented SILC protocol compliant public key. Added public
2545 and private key saving to and loading from files.
2547 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2548 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2549 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2550 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2551 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2553 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2554 silc_pkcs_load_[public/private]_key.
2556 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added silc_server_get_route (route.[ch]) to get connection
2559 data for the fastest route for given ID.
2561 * Implemented INVITE command on client and server. The command
2562 were re-defined in the SILC Protocol Specification and the
2563 implementation now complies with the specification.
2565 * Implemented PING command on client and server.
2567 * Implemented NAMES command on client and server. The server side
2568 supports currently only normal server not router server yet.
2569 Some changes to NAMES definition in SILC protocol specification.
2571 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Implemented LEAVE command on client and server.
2575 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2576 again. This change was made to the protocol as well. Server
2577 should not violate the protocol specification anymore.
2579 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2582 was tested. SOCKS4 was not but should work anyway.
