1 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added function silc_server_get_client_resolve to find the
4 client entry by ID from all ID lists and then resolve it
5 (using WHOIS) if it cannot be found. Affected file is
8 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Implemented the BAN command to the client library.
12 * The JOIN command in the server now checks the invite list
15 * Changed the silc_command_reply_payload_encode_va and the
16 silc_command_payload_encode_va to support that if argument is
17 NULL it ignores and checks the next argument. Affected file
18 lib/silccore/silccommand.c.
20 * Added silc_server_send_notify_ban to send the BAN notify
23 * Chaned the silc_notify_payload_encode to support that if
24 argument is NULL it ignores and checks the next argument.
25 Affected file lib/silccore/silcnotify.c.
27 * Tested ban lists in router environment successfully.
29 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
31 * Implemented BAN command to the server, in silcd/command.[ch].
33 * Removed the BAN and INVITE_LIST modes from the CMODE command
36 * Added function silc_string_match to regex match two strings.
37 Affected files lib/silcutil/silcutil.[ch].
39 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Redefined parts of the SilcChannelEntry in the server to support
42 the new ban and invite lists.
44 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
46 * Redefined the INVITE command. The same command can be used to
47 invite individuals to the channel but also to manage the invite
48 list of the channel (to add to and remove from the invite list).
49 Updated the protocol specs.
51 * Added new command SILC_COMMAND_BAN that can be used to manage
52 the ban list of the channel. Updated the protocol specs.
54 * Removed the channel modes: the SILC_CMODE_BAN and the
55 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
56 in the CMODE command. The equivalent features are now available
57 using INVITE and BAN commands. Updated the protocol specs.
59 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
60 in the network about change in the current ban list. The notify
61 type is not used by the client.
63 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
64 support the invite lists.
66 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added new function silc_string_regexify that converts string
69 including wildcard characters into regex string that can
70 be used by the GNU regex library. Added into the file
71 lib/silcutil/silcutil.[ch].
73 Added silc_string_regex_combine to combine to regex strings
74 into one so that they can be used as one regex string by
75 the GNU regex library. Added into the file
76 lib/silcutil/silcutil.[ch].
78 Added silc_string_regex_match to match two strings. It returns
79 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
81 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Imported GNU regex to the soruce tree into lib/contrib.
84 Fixed some compiler warning from the regex.c.
86 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * Fixed MOTD command in the server to work in router environment.
90 * Fixed the MOTD command in the client library to support
91 the server argument in the command.
93 * Added `nickname_len' argument to the silc_idlist_add_client
94 in the server, as the `nickname' argument may be binary data
97 * Added silc_idlist_get_channels to return all channels from
100 * Implemented LIST command to the server. Affected file is
103 * Implemented the LIST command to the client library and on the
106 * Added [<user count>] argument to the LIST command reply.
107 With private channels the user count is not shown.
109 * Updated TODO and README.
111 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * The client entry's data.registered must be TRUE even with
114 global client entry on global client list. The data.registered
115 is used to check whether the client is anymore in the network,
116 for example with WHOWAS command so it must be valid.
118 * Fixed the WHOWAS command in the server. It now actually works
119 in router environment. Added function into silcd/command_reply.c
120 silc_server_command_reply_whowas_save.
122 * Added silc_idlist_purge function to the silcd/idlist.c
123 to periodically purge the ID Cache.
125 * Fixed INFO command in the server. It works now in router
126 environment. Added <server name> argument to the INFO command
127 reply. Updated the protocol specs.
129 * Fixed minor bug in silc_idcache_purge to not purge if the
130 expire value is zero.
132 * Fixed various bugs in WHOIS and IDENTIFY command handling as
133 they were buggy because of the WHOWAS information.
135 * Fixed local command MSG to handle the async resolving of
136 the remote client properly. It used to fail the first MSG.
137 Affected file silc/local_command.c.
139 * Added `data_len' field to SilcIDCache context.
141 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Update TODO. Todo in commands in the server.
145 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
148 used by routers as broadcast packet to inform other routers
149 about the changed user mode.
151 Implemented the notify handling in the server. Affected file is
152 silcd/packet_receive.c. Added the function
153 silc_server_send_notify_umode to the silcd/packet_send.[ch].
155 * Added new generic Channel Payload and deprecated the New Channel
156 Payload. The New Channel Payload is now the generic Channel
159 * Added new argument `mode' to the silc_server_send_new_channel
160 as it is required in the Channel Payload now.
162 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
163 and created a new and real SilChannelPayload to represent the
164 new generic Channel Payload. Implemented the encode/decode
165 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
167 * Added silc_server_get_client_channel_list to return the list
168 of channels the client has joined for WHOIS command reply.
169 Affected file silcd/server.[ch].
171 * Implemented the channel list sending in the WHOIS command reply
172 in server and in the client.
174 Implemented the channel list displaying on the user interface
175 as well. Affected file silc/client_ops.c.
177 * Added silc_channel_payload_parse_list to parse list of Channel
178 Payloads. It returns SilcDList list of SilcChannelPayloads.
179 Client for example can use this function to parse the list of
180 channels it receives in the WHOIS command reply. The caller
181 must free the list by calling silc_channel_payload_list_free.
182 Affected files lib/silccore/silcchannel.[ch].
184 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Added one new argument <user mode> to the WHOIS command reply
187 to return the mode of the user in SILC. Updated the protocol
190 Implemented it to the server and client.
192 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Fixed the mode printing on the user interface on joining.
195 Affected file silc/client_ops.c.
197 * Implemented the UMODE command and user modes in general to the
198 client library and to the user interface.
200 * Implemented the UMODE command to the server.
202 * The server now sends UNKNOWN_COMMAND error status if client sends
203 unknown command. Affected file silcd/command.c.
205 * All server commands now handle the command identifier the right
206 way when sending the command reply to the client. The client can
207 use to identify the command replies with the identifier.
209 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Added silc_server_get_client_route to resolve the route to
212 the client indicated by the client ID. Affected file is
215 * Added silc_server_relay_packet as general function to relay
216 packet to arbitrary destination. This deprecates functions
217 like _send_private_message_key, _relay_notify etc. Affected
218 file is silcd/packet_send.[ch].
220 Removed silc_server_send_key_agreement,
221 silc_server_send_private_message_key and
222 silc_server_packet_relay_notify functions from the file
223 silcd/packet_send.[ch].
227 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
228 server. Affected file silcd/packet_receive.[ch].
230 * Implemented the KILL command to the client. Implemented the
231 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
232 Affected files lib/silcclient/command[_reply].c and
233 lib/silcclient/client_notify.c. Implemented the KILL notify
234 printing in the user inteface.
236 * Fixed a lot silc_parse_nick memory leaks from the client
237 library in the file lib/silcclient/command.c.
239 * Changed the silc_server_send_notify_on_channels's `sender'
240 argument from SilcSocketConnection to SilcClientEntry to
241 check the sender as entry and not as connection object and not
242 to send to the client provided as argument. The affected file
243 is silcd/packet_send.[ch].
245 * The notify packets that are destined directly to the client used
246 to not to be processed by the server. Now changed that and the
247 server processes all notify packets. After relaying the packet
248 to the client the notify packet is processed in the server.
250 * The silc_server_free_client_data now checks whether there is
251 pending outgoing traffic for the client and purges the data to
252 the network before removing the client entry.
254 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
257 an client is killed from the SILC Network. Updated the protocol
260 Added new function silc_server_send_notify_killed to the
261 silcd/packet_send.[ch].
263 * Added function silc_server_packet_relay_notify to relay notify
264 packets that are destined directly to a client. In this case
265 the server does not process the notify packets but merely relays
266 it to the client. Affected file silcd/packet_send.[ch].
268 Added also silc_server_packet_process_relay_notify to check
269 whereto relay the notify. Affected file is
270 silcd/packet_receive.[ch].
272 * Implemented the KILL command to the server.
276 * Added the backup schema desgined last fall to the protocol
277 specs for everyone to see. The specification is in the
278 *-spec-xx.txt draft and the packet type definitions for the
279 backup routers is in *-pp-xx.txt draft. Thusly, added also
280 new packet type SILC_PACKET_CELL_ROUTERS.
282 * A big security problem in the implementation discovered. The
283 signoff of an client did not cause new channel key generation
284 which it of course should've done. The channel keys must be
285 always re-generated when client leaves (or signoffs) the channel.
286 The silc_server_remove_from_channels funtion now handles
287 the channel key re-generation.
289 * Added `sender' argument to the silc_server_send_notify_on_channels
290 to not to send the client provided as argument. Affected file
291 silcd/packet_send.[ch].
293 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Implemented OPER and SILCOPER commands into the server and
298 * Added silc_auth_verify and silc_auth_verify_data to verify
299 the authentication directly from the authentication payload.
300 It supports verifying both passphrase and public key based
301 authentication. Affected file lib/silccore/silcauth.[ch].
303 * Added `hash' field to the SilcIDListData structure. It is the
304 hash negotiated in the SKE protocol. Affected file is
307 * Slight redesigning of the SilcAuthPayload handling routines.
308 Do not send SilcPKCS but SilcPublicKey as argument.
310 * Implemented the public key authentication support to the
311 serverconfig. The public key is loaded fromthe provided path
312 and saved as authentication data to void * pointer. Thus,
313 changed the unsigned char *auth_data to void *auth_data;
315 * Fixed SHUTDOWN command to send the reply before the server
316 is shutdown. :) Affected file silcd/command.c.
318 * Fixed fatal bug in CONNECT command. The hostname was invalid
319 memory and server crashed. Affected file silcd/command.c.
321 * Fixed fatal bug in CLOSE command. The server_entry became
322 invalid but was referenced later in the command. Affected file
325 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Fixed fatal bug in failure packet handling. Server ignored
328 the failure and thus crashed when it came.
332 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
335 that the command may be executed only once in (about) 2 seconds.
336 The old SILC_CF_LAG flag is same but allows command bursts up
337 to five before limiting.
339 Added the support for CF_LAG and CF_LAG_STRICT flags to the
340 server code. Various commands now includes the CF_LAG_STRICT
341 flag to disallow any kind of miss-use of the command.
343 * Fixed the silc_buffer_unformat to not to allocate any data
344 if the length of the data is zero. It used to allocate the
345 length + 1. Affected file lib/silcutil/silcbuffmt.c.
347 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Changed the format of AdminConnection configuration section
350 in the server. Added username of the admin to the format.
351 Affected files silcd/serverconfig.[ch].
353 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
354 to return admin configuration data by host, username and/or
357 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Implemented WHOWAS command to the server. Added the functions:
361 silc_server_command_whowas_parse,
362 silc_server_command_whowas_send_reply,
363 silc_server_command_whowas_from_client and
364 silc_server_command_whowas_from_server
366 * Added <Client ID> argument to the WHOWAS command reply. Updated
367 the protocol specs accordingly.
369 * Implemented WHOWAS command and command_reply to the client
372 Implemented the WHOWAS printing on the user interface.
374 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Added new argument to the WHOWAS command reply, the real name.
377 It is an optional argument. Updated the protocol specs.
379 * Added SilcIDCacheDestructor callback that is registered when
380 the SilcIDCache is allocated. The callback is called when
381 an cache entry in the ID Cache expires, or is purged from the
382 cache. Added into lib/silccore/idcache.[ch].
384 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
385 to destruct the client entries when the cache entry expires.
386 Other ID Cache's in server and in the client library ignores
389 * If the ID Cache entry's `expire' field is zero then the entry
390 never expires. Added boolean `expire' argument to the
391 silc_idcache_add function in the lib/silccore/idcache.[ch].
392 If it is TRUE the default expiry value is used.
394 * Added silc_server_free_client_data_timeout that is registered
395 when client disconnects. By default for 5 minutes we preserve
396 the client entry for history - for WHOWAS command.
398 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Added support to the server to enforce that commands are not
401 executed more than once in 2 seconds. If server receives
402 commands from client more frequently, timeout is registered
403 to process the commands. Affected file silcd/command.c.
404 Added new function silc_server_command_process_timeout.
406 * Changed NICK_NOTIFY handling in client library to check that
407 if the client's nickname was changed, so there is no need to
408 resolve anything from the server.
410 * Removed error printing from the WHOIS and IDENTIFY commands.
411 If error occurs then it is ignored silently in the client library.
412 The application, however, may map the received error to
413 human readable error string. The application currently maps
414 the NO_SUCH_NICKNAME error to string.
416 * Made the command status message public to the application. Moved
417 them from lib/silcclient/command_reply.c to
418 lib/silcclient/command_reply.h. The application can map the
419 received command status to the string with the
420 silc_client_command_status_message function.
422 * Added check to the server to check that client's ID is same
423 as the Source ID in the packet the client sent. They must
426 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Added dist-bzip hook to the Makefile.am to make bzip2
429 compressed distributions.
431 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Server now enforces the maximum length for the nickname and
434 the channel as protocol specification dictates. 128 bytes for
435 nickname and 256 bytes for channel name.
437 * Moved the WHOIS printing to the application. The client libary
438 does not print out the WHOIS information anymore, the application
439 must do it. Renamed silc_client_command_reply_whois_print to
440 the silc_client_command_reply_whois_save.
442 The client's idle time is also sent to the application now, and
443 the idle is shown on screen.
445 * Added silc_client_command_reply_identify_save to save the
446 received IDENTIFY entries.
448 * Do not check for channel private keys in message sending and
449 reception if the channel does not have the PRIVKEY mode set.
450 Affected file lib/silclient/client_channel.c.
452 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
455 just surfaced after chaning the JOIN procedure.
457 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Added silc_client_get_clients_by_list to get client entries
460 from Client ID list, that is returned for example by JOIN
461 and USERS command replies. The application should use this
462 function for example when JOIN command reply is received to
463 resolve the clients already on the channel (library does not
464 do that anymore as USERS command reply is not used in the JOIN
465 procedure anymore). Affected files lib/silcclient/silcapi.h and
466 lib/silcclient/idlist.c.
468 * JOIN command reply and USERS command reply returns now SilcBuffer
469 pointers instead of unsigned char pointers when returning
470 the client list and mode list.
472 * Added <Client ID> argument to the JOIN command reply, mainly
473 for the server to identify for which client the command was
474 originally sent. Updated protocol specs accordingly.
476 * Added SilcDlist private_key pointer to the SilcChannelEntry
477 in the client to support the channel private keys. Affected
478 file is lib/silcclient/idlist.h.
480 * Added SilcChannelPrivateKey argument to the function
481 silc_client_send_channel_message so that application can choose
482 to use specific private ke if it wants to. If it is not provided,
483 the normal channel key is used, unless private keys are set.
484 In this case the first (key that was added first) is used
485 as the encryption key.
487 * Implemented the support for channel private key handling.
488 Implemented the following functions:
490 silc_client_add_channel_private_key,
491 silc_client_del_channel_private_keys,
492 silc_client_del_channel_private_key,
493 silc_client_list_channel_private_keys and
494 silc_client_free_channel_private_keys
496 Affected file lib/silcclient/client_channel.c.
498 * Added the support for the private keys in the channel message
499 sending and encryption and in the message reception and
500 decryption. Affected funtions are
501 silc_client_send_channel_message and silc_client_channel_message.
503 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
505 * Added SKE's key verify callback to the client library's
506 KE protocol context. Affected files lib/silcclient/protocol.[ch].
508 * Removed the statement that server (or router) must send USERS
509 command reply when joining to the channel so that the client
510 knows who are on the channel. Instead, the client list and
511 client's mode list is now sent in the JOIN command reply to the
512 client who joined channel. This is better solution.
514 * Added function silc_server_get_users_on_channel and function
515 silc_server_save_users_on_channel to the silcd/server.[ch].
517 * Removed function silc_server_command_send_users from the
520 * Do not show topic on the client library anymore. The topic is
521 sent in the command reply notify to the application and the
522 application must show the topic now.
524 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Added client searching by nickname hash into the IDENTIFY and
527 WHOIS commands in the server as they were clearly missing from
528 them. Affected file is silcd/command.c.
530 * Fixed a bug in private message receiving in the client library.
531 The remote ID was freed and it wasn't supposed, now it is
534 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Minor fix to the channel payload; allocate the data area, as it
537 needs to be of specific length.
539 * If the key agreement port is zero then the operating
540 system will define the bound port. Affected files are
541 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
543 * Added new function silc_channel_payload_decrypt into the file
544 lib/silccore/silcchannel.[ch].
546 * Moved the channel message etc, check from silc_packet_decrypt
547 to applications. The library calls now a generic
548 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
549 when the packet is either normal or special. This was done to
550 allow more wide range of checking that was not allowed when
551 the code was in library. Now applications can do virtually any
552 checks to the packet and return to the library the decision how
553 the packet should be processed. Affected files are
554 lib/silccore/silcpacket.[ch].
556 Added silc_server_packet_decrypt_check to the server and
557 silc_client_packet_decrypt_check to the client library.
559 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
560 to send with specified source and destination information.
562 * Channel message delivery between routers was broken after the
563 channel key distribution was fixed earlier. The channel key
564 was used be to distributed to other routers as well which is not
565 allowed by the protocol. Now this is fixed and channel keys
566 really are cell specific and the channel message delivery between
567 routers comply with the protocol specification.
569 * Fixed various commands in server to check also the global list
570 for the channel entry and not just the local list. The affected
571 file silcd/command.c.
573 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Added assert()s to buffer formatting and unformatting routines
576 to assert (if --enable-debug) when error occurs. Affected
577 file: lib/silcutil/silcbuffmt.c.
579 * Changed to auto-reconnect to check whether the remote host is
580 router and register the re-connect timeout if it is. It used
581 to check that whether we are normal server, but router must do
582 auto-reconnect with another router as well. Affected file
585 * Removed the [<key len>] option from CMODE command as the cipher
586 name decides the key length, nowadays. See the defined ciphers
587 from the protocol specification.
589 * Added [<hmac>] option to the CMODE command to define the HMAC
590 for the channel. Added SILC_CMODE_HMAC channel mode.
592 * Added [<hmac>] option for the JOIN command so that user can
593 select which HMAC is used to compute the MACs of the channel
596 * Added Hmac field to the Channel Message Payload. The integrity
597 of plaintext channel messages are now protected by computing
598 MAC of the message and attaching the MAC to the payload. The
599 MAC is encrypted. Now, it is clear that this causes some
600 overhead to the size of the packet but rationale for this is that
601 now the receiver can verify whether the channel message decrypted
602 correctly and also when private keys are set for the channel the
603 receiver can decrypt the packet with several keys and check from
604 the MAC which key decrypted the message correctly.
606 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
607 lib/silccrypt/silccipher.[ch].
609 * Added silc_hash_len to return the digest length into the
610 lib/silcrypt/silchash.[ch].
612 * Rewrote parts of Silc Channel Payload interface in the
613 lib/silccore/silcchannel.[ch]. The encode function now also
614 encrypts the packet and parse function decrypts it.
616 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Fixed a minor formatting bug in the SKE's key material processing.
619 It actually might have processed the keys wrong way resulting
622 * Redefined the mandatory HMAC algorithms and added new algorithms.
623 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
624 and hmac-md5 truncated to 96 bits. The mandatory is now
625 hmac-sha1-96. Rest are optional (including the one that used
626 to be mandatory). Rationale for this is that the truncated HMAC
627 length is sufficient from security point of view and can actually
628 make the attack against the HMAC harder. Also, the truncated
629 HMAC causes less overhead to the packets. See the RFC2104 for
632 * Added new [hmac] configuration section. The SKE used to use
633 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
634 is of course wrong. The official names that must be proposed in
635 the SKE are the ones defined in the protocol specification
636 (hmac-sha1-96 for example). The user can configure any hmac
637 using any hash function configured in the [hash] section. At
638 least, the mandatory must be configured.
640 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
642 * Added HMAC list to the SKE proposal list. It has now both
643 hash algorithm list and HMAC list. This makes the protocol
644 incompatible with previous versions. The SKE now seems to work
645 the way it is supposed to work, for the first time actually.
647 * Defined plain Hash algorithms to the protocol specification.
650 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Implemented support for key agreement packets into the server.
653 Added functions silc_server_key_agreement and
654 silc_server_send_key_agreement. Other than these functions,
655 server has nothing to do with this packet.
657 * Added support for private message key packets into the server.
658 Added functions silc_server_private_message_key and
659 silc_server_send_private_message_key.
663 * Changed the silc_[client|server]_protocol_ke_set_keys to be
664 called in the protocol's final callback instead in the END
665 protocol state. This makes a little more sense and in the same
666 time in client we can use the same protocol routines for normal
667 key exchange and to key agreement packet handling as well.
669 * Added to both client's and server's KE protocol context the
670 SilcSKEKeyMaterial pointer to save the key material. We will
671 bring the key material to the protocol's final callback by doing
672 this. The final callback must free the key material.
674 * Added SKE's packet_send callback into client's KE protocol
675 context so that the caller can choose what packet sending function
676 is used. This way we can use different packet sending when
677 doing normal SKE when doing key agreement packet handling (in
678 the key agreement packet handling we do not want to encrypt
681 * Implemented the responder side of the key agreement routines
682 in the client. The client can now bind to specified port and
683 accept incoming key negotiation. The key material is passed
684 to the application after the protocol is over.
686 * Implemented the processing of incoming Key Agreement packet
687 in the client. Added function silc_client_key_agreement to
690 * Implemented the intiator side of the key agreement routines
691 in the client. The client can now initiate key agreement with
692 another remote client. The key material is passed to the
693 application after the protocol is over.
695 * Created client_keyagr.c to include all the key agreement
698 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
699 SILC_TASK_CALLBACK except that it is not static.
701 * Created client_notify.c and moved the Notify packet handling
702 from the client.[ch] into that file.
704 * Created client_prvmsg.c and moved all private message and
705 private message key routines from the client.[ch] into that file.
707 * Create client_channel.c and moved all channel message and
708 channel private key routines from the client.[ch] into that file.
710 * Changed silc_client_get_client_by_id_resolve to resolve with
711 WHOIS command instead of IDENTIFY command, in the file
712 lib/silclient/idlist.c.
714 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Implemented the SKE's responder side to the Client library.
718 * When FAILURE is received to the protocol do not trust it
719 blindly. Register a timeout to wait whether the remote closes
720 the connection as it should do it, only after that process the
721 actual failure. This was changed to both client and server.
723 * Added client_internal.h to include some of the structures
724 there instead of client.h in lib/silcclient/.
726 * Added function silc_task_unregister_by_callback to unregister
727 timeouts by the callback function.
729 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Some "Incomplete WHOIS info" errors has been appearing on the
732 log files. Took away the entry->userinfo check from WHOIS
733 reply sending. The entry->userinfo is now " " if client did not
734 provide one. I thought this was fixed earlier but something
735 is wrong still. Let's see if the error still appears.
737 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Fixed a minor bug in the login when the channel key is
740 re-generated in the server. It used to generate the key in
741 wrong order and thus caused problems in the channel traffic.
743 * Fixed a minor bug in channel key distsribution after
744 KICK command. The key was not sent to the router even though
747 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added silc_ske_process_key_material_data as generic routine
750 to process any key material as the SILC protocol dictates. The
751 function is used by the actual SKE library but can be used by
752 applications as well. This relates to the private message keys
753 and the channel private keys since they must be processed the
754 same way the normal SILC session keys. The protocol dictates
755 this. Affected files: lib/silcske/silcske.[ch].
757 Added also silc_ske_free_key_material to free the
758 SilcSKEKeyMaterial structure.
760 * Defined silc_cipher_set_key function to set the key for
761 cipher without using the object's method function. The affected
762 files: lib/silccrypt/silccipher.[ch].
764 * Implemented silc silc_client_add_private_message_key,
765 silc_client_add_private_message_key_ske,
766 silc_client_del_private_message_key,
767 silc_client_list_private_message_keys and
768 silc_client_free_private_message_keys functions in the
771 Added functions silc_client_send_private_message_key to send
772 the Private Message Key payload and silc_client_private_message_key
773 to handle incoming Private Message Key payload.
775 * Added Cipher field to the Private Message Key payload to set
776 the cipher to be used. If ignored, the default cipher defined
777 in the SILC protocol (aes-256-cbc) is used.
779 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Removed lib/silcclient/ops.h file.
783 Redefined parts of the SILC Client Library API. Created new
784 file silcapi.h that deprecates the ops.h file and defines the
785 published Client Library API. Defined also private message key
786 API and channel private key API into the file.
788 This is the file that the application must include from the
789 SILC Client Library. Other files need not be included by
790 the application anymore.
792 * Added new key_agreement client operation callback and also
793 defined the Key Agreement library API for the application.
795 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
798 is used by clients to request key negotiation between another
799 client in the SILC network. If the negotiation is started it
800 is performed using the SKE protocol. The result of the
801 negotiation, the secret key material, can be used for example
802 as private message key.
804 Implemented the Key Agreement payload into the files
805 lib/silccore/silauth.[ch].
807 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Redefined ciphers for the SILC protocol. Added some new ciphers
810 and defined the key lengths for the algorithms. Changed the
811 code accordingly. The default key length is now 256 bits.
813 * Fixed SKE key distribution function silc_ske_process_key_material
814 when the key length is more than 128 bits. The default key
815 length in SILC is now 256 bits.
817 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
818 to indicate unsupported algorithm.
820 * Renamed rijndael.c to aes.c and all functions as well.
822 * Fixed a long standing channel key setting bug in client library.
823 Weird that it has never surfaced before.
825 * Fixed bug in channel deletion. If the entire channel is removed
826 then it must also delete the references of the channel entry
827 from the client's channel list as the client's channel entry and
828 the channel's client entry share same memory.
830 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Implemented CONNECT and SHUTDOWN commands in the client.
834 * Implemented CLOSE command to the client.
836 * Added the function silc_idlist_find_server_by_name into the
837 files silcd/idlist.[ch].
839 Added the function silc_idlist_find_server_by_conn into the
840 files silcd/idlist.[ch].
842 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * DIE command was renamed to SHUTDOWN. Updated the both code
847 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
848 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
850 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
853 * Added function silc_server_create_connection function to create
854 connection to remote router. My server implementation actually
855 does not allow router to connect to normal server (it expects
856 that normal server always initiates the connection to the router)
857 so the CONNECT command is only good for connecting to another
860 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
863 or some other client was kicked from the channel.
865 Implemented the handling of the notify type to both client
868 Implemented silc_server_send_notify_kicked to send the KICKED
869 notify. It is used to send it to the server's primary router.
871 * Implemented the KICK command into server and client.
873 * Added `query' argument to the silc_idlist_get_client function
874 to indicate whether to query the client from server or not if
877 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
878 to indicate that the client is not channel founder.
882 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Removed the rng context from SilcPacketContext structure and
885 changed that the packet routine uses the Global RNG API.
887 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Added support for quit message that client can "leave" on the
890 channel when it quits the SILC. It is ditributed inside the
891 SILC_NOTIFY_TYPE_SIGNOFF notify type.
893 Added silc_server_free_client_data that will take the
894 signoff message as argument.
896 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
898 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Updated parts of the protocol specification to keep it up
903 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
906 payloads in one packet.
908 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
909 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
910 use now the new List flag.
912 * Also deprecated the following packet types: REPLACE_ID,
913 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
915 * Added list support for Notify packet in server.
917 * Added silc_server_send_notify_channel_change to send the
918 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
919 the silc_server_send_replace_id.
921 * Added silc_server_send_notify_nick_change to send the
922 NICK_CHANGE notify type. Deprecates the function
923 silc_server_send_replace_id.
925 * Added silc_server_send_notify_join to send the JOIN notify type.
926 Deprecates the function silc_server_send_new_channel_user.
928 * Added silc_server_send_notify_leave to send LEAVE notify type.
929 Deprecates the function silc_server_send_remove_channel_user.
931 * Added silc_server_send_notify_cmode and
932 silc_server_send_notify_cumode to send CMODE and CUMODE notify
933 types. Deprecates the silc_server_send_set_mode function.
935 * Added SERVER_SIGNOFF notify type to indicate that server has
936 quit. This means that all clients on the channel from that
937 server will drop. This can be also used when netsplit happens.
939 Deprecated REMOVE_ID packet type since it is not needed anymore
942 Added silc_server_send_notify_server_signoff to send the
943 SERVER_SIGNOFF notify type. Deprecates the function
944 silc_server_send_remove_id.
946 Added also silc_server_send_notify_signoff to send the
949 * Employed the PKCS #1. It is the mandatory way to do RSA in the
950 SILC protocol from this day on. Changed the protocol
951 specification as well.
953 * Added silc_server_send_notify_topic_set to send TOPIC_SET
954 notify type. It is used between routers to notify about
955 topic changes on a channel.
957 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
960 * Partly updated the protocol specification to comply with the
961 changes now made. It is still though a bit outdated.
963 * The JOIN notify type now takes one extra argument <Channel ID>.
964 The packet used to be destined to the channel but now the
965 JOIN type may be sent as list thus it is impossible to
966 destine it to any specific channel. By adding this argument
967 it is again possible.
969 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Added CREDITS file. The CHANGES and CREDITS file will appear
972 in the distribution as well.
974 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
977 types in the server's silcd/packet_receive.c.
979 * Implemented CMODE and CUMODE to work in router environment.
981 * Fixed minor encoding and decoding buglet from the
982 lib/silccore/silcmode.c.
984 * Fixed buffer overflow from lib/silcclient/command.c in USERS
987 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
989 * Changed all SilcConfigServer* and silc_config_server* to
990 SilcServerConfig* and silc_server_config*, respectively.
993 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Associated the ID (client or server ID) to the Authentication
996 Payload to avoid any possibility of forging. Updated the
997 protocol specification and the code accordingly.
999 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * The RSA key length is now save to the RsaKey context in the
1002 key generation process in lib/silccrypt/rsa.c. The key length
1003 is now used to figure out the maximum size of the block allowed
1004 to be encrypted/signed.
1006 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1007 is equivalent to the silc_mp_mp2bin but does not allocate any
1010 * Changed silc_mp_mp2bin API to take length argument. If it is
1011 non-zero then the buffer is allocated that large. If zero, then
1012 the size is approximated using silc_mp_sizeinbase, which however
1015 * Created Global RNG API which is global RNG that application can
1016 initialize. After initializing, any routine anywhere in the
1017 code (including library) can use RNG without allocating a new
1018 RNG object. This was done to allow this sort of use of the
1019 RNG in code that has no chance to allocate RNG object. All
1020 applications currently allocate this and many routines in the
1021 library use this. Affected file lib/silccrypt/silcrng.[ch].
1023 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1024 it to use the Global RNG API.
1026 * Defined Authentication Payload into protocol specification that
1027 is used during SILC session to authenticate entities. It is
1028 used for example by client to authenticate itself to the server
1029 to obtain server operator privileges.
1031 Implemented this payload into the lib/silccore/silcauth.[ch].
1032 Implemented also routines for public key based authentication
1033 as the new protocol specification dictates.
1035 Moved definitions of different authentication methods from
1036 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1038 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1039 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1040 silc_pkcs_verify_with_hash functions into the file
1041 lib/silccrypt/silcpkcs.[ch].
1043 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * The client entry's userinfo pointer must be always valid.
1046 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1047 will fail since it requires the userinfo. Now, the userinfo
1048 is allocated as "" if actual userinfo does not exist. Actually,
1049 it must exist and it is totally Ok to drop client connections
1050 that does not announce the userinfo. However, we will make
1051 this workaround for now.
1053 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1054 to return the remote port by socket.
1056 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1059 SILC_SERVER_PENDING_EXEC and added an new macro
1060 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1061 data or when error occurs while processing the pending command.
1063 Added new argument `destructor' into silc_server_command_pending
1064 and to the SilcServerCommandPending object. This destructor is
1065 now called after calling the pending callback or if error occurs
1066 immediately. If error occurs the actual pending callback won't
1067 be called at all - only the destructor. The destructor may be
1068 NULL if destructor is not needed.
1070 All this applies for client library code as well. Similar
1071 changes were made there as well for the pending commands.
1073 In the client, the application must now allocate the
1074 SilcClientCommandContext with the silc_client_command_alloc
1077 * Added reference counter to the SilcServerCommandContext. Added
1078 function silc_server_command_alloc and silc_server_command_dup
1081 Same type of functions added to the client library for the same
1084 * Removed the cmd_ident from IDListData away since it is now
1085 global for all connections. It is the command identifier used
1086 in command sending and with pending commands. The affected file
1089 * Added reference counter to the SilcSocketConnection objecet to
1090 indicate the usage count of the object. The object won't be
1091 freed untill the reference counter hits zero. Currently only
1092 server uses this, and client ignores it. The client must be
1093 set to use this too later. The affected files are
1094 lib/silccore/silcsockconn.[ch]. Added also the function
1095 silc_socket_dup to increase the reference counter.
1097 This was mainly added because it is possible that the socket
1098 is removed underneath of pending command or other async
1099 operation. Now it won't be free'd and proper DISCONNECTING
1100 flags, etc. can be set to avoid sending data to connection that
1101 is not valid anymore.
1103 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1104 the connection. After that it sets SILC_SET_DISCONNECTED.
1105 It is, however, possible that the socket data is not still freed.
1106 The silc_server_packet_process now checks that data is not
1107 read or written to connection that is DISCONNECTED. The socket
1108 get's freed when the reference counter hits zero.
1110 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1112 * Changed the client operation API: channel_message operation's
1113 `sender' is now the client entry of the sender, not the nickname
1114 and the `channel' is the channel entry, not the channel name.
1116 In the private_message operation the `sender' is now also the
1117 client entry of the sender not the nickname.
1119 Affected file is lib/silcclient/ops.h and all applications
1120 using the client operations.
1122 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Moved the calling of ops->connect() from connect_to_server_final
1125 into receive_new_id functin since that is the point when the
1126 client is actually allowed to send traffic to network. The
1127 affected file is lib/silcclient/client.c.
1129 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1132 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1133 (if needs broadcasting) instead of broadcasting the packets one
1134 by one which would make a burst in the network traffic.
1136 * Added `broadcast' argument to the functions in silcd/server.[ch]
1137 silc_server_create_new_channel[_with_id] to indicate whether
1138 to send New Channel packet to primary router.
1140 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Added new function into the silcd/server.[ch] files:
1143 silc_server_create_new_channel_with_id to create new channel with
1144 already existing Channel ID.
1146 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1147 lib/silccore/silcpacket.h. This packet is used t send list of
1148 Set Mode payloads inside one packet. Server uses this to set
1149 the modes for the channels and clients on those channels, that it
1150 announced to the router when it connected to it. The protocol
1151 specification has been updated accordingly.
1153 * The silc_server_new_channel did not handle the packet coming
1154 from normal server as it normally does not send that. However,
1155 when it announces its channels it does send it. Implemented
1156 the support for that.
1158 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1159 into the file lib/silccore/id.h.
1161 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Fixed memory leaks in the functions silc_idlist_del_client,
1164 silc_idlist_del_channel and silc_idlist_del_server in the file
1165 silcd/idlist.c. All of those leaked like a sieve.
1167 * Fixed some small memory leaks in the client's function
1168 silc_client_notify_by_server.
1170 * Added functions into silcd/server.c: silc_server_announce_clients,
1171 silc_server_announce_channels and silc_server_announce_server.
1172 These functions are used by normal and router server to announce
1173 to its primary router about clients, channels and servers (when
1174 router) that we own. This is done after we've connected to the
1177 These functions effectively implements the following packet types:
1178 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1179 and SILC_PACKET_NEW_ID_LIST.
1181 * Added new functions into the silcd/packet_receive.[ch]:
1182 silc_server_new_id_list, silc_server_new_channel_list and
1183 silc_server_new_channel_user_list to handle the incoming
1184 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1186 * Added support of changing Channel ID in the function
1187 silc_server_replace_id. If the server that announces a channel
1188 to the router already exists in the router (with same name but
1189 with different Channel ID), router is responsible to send
1190 Replace ID packet to the server and force the server to change
1191 the Channel ID to the one router has.
1193 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1194 client that the Channel ID has been changed by the router. The
1195 normal server sends this to the client. Client must start using
1196 the new Channel ID as the channel's ID.
1198 Implemented handling of this new type into lib/silcclient/client.c
1199 into the function silc_client_notify_by_server.
1201 * Added new function silc_idlist_replace_channel_id into the files
1202 silcd/idlist.[ch] to replace the Channel ID.
1204 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Call silc_server_command_identify_check always when processing
1207 the IDENTIFY command in silcd/command.c
1209 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1211 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1212 send keepalive packets. The packet can be sent by clients,
1213 servers and routers.
1215 Added function silc_socket_set_heartbeat into the file
1216 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1217 If not set, the heartbeat is not performed. The actual
1218 heartbeat is implemented in the low level socket connection
1219 library. However, application is responsible of actually
1222 Added silc_server_send_heartbeat to send the actual heartbeat
1223 packet into silcd/packet_send.[ch]. Server now performs
1224 keepalive with all connections.
1226 * Added silc_task_get_first function into lib/silcutil/silctask.c
1227 to return the timeout task with shortest timeout. There was a bug
1228 in task unregistration that caused problems. TODO has been
1229 updated to include that task system must be rewritten.
1231 * The client library will now resolve the client information when
1232 receiving JOIN notify from server for client that we know but
1233 have incomplete information.
1235 * Rewrote parts of silc_server_remove_from_channels and
1236 silc_server_remove_from_one_channel as they did not remove the
1237 channel in some circumstances even though they should've.
1239 * Encryption problem encountered in server:
1241 The LEAVE command used to send the Channel Key packet to the
1242 router immediately after generating it. However, the code
1243 had earlier sent Remove Channel user packet but not immediately,
1244 ie. it was put to queue. The order of packets in the router
1245 was that Channel Key packet was first and Remove Channel User
1246 packet was second, even though they were encrypted in the
1247 reverse order. For this reason, MAC check failed. Now, this
1248 is fixed by not sending the Channel Key packet immediately but
1249 putting it to queue. However, this is more fundamental problem:
1250 packets that are in queue should actually not be encrypted
1251 because packets that are sent immediately gets encrypted
1252 actually with wrong IV (and thus MAC check fails). So, packets
1253 that are in queue should be encrypted when they are sent to
1254 the wire and not when they put to the queue.
1256 However, the problem is that the current system has not been
1257 designed to work that way. Instead, the packet is encrypted
1258 as soon as possible and left to the queue. The queue is then
1259 just purged into wire. There won't be any fixes for this
1260 any time soon. So, the current semantic for packet sending
1263 o If you send packet to remote host and do not force the send
1264 (the packet will be in queue) then all subsequent packets to the
1265 same remote host must also be put to the queue. Only after the
1266 queue has been purged is it safe again to force the packet
1269 o If you send all packets immediately then it safe to send
1270 any of subsequent packets through the queue, however, after
1271 the first packet is put to queue then any subsequent packets
1272 must also be put to the queue.
1274 Follow these rules and everything works fine.
1276 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Added new function silc_server_remove_clients_by_server to
1279 remove all client entries from ID list when the server connection
1280 is lost. In this case it is also important to invalidate all
1281 client entires as they hold the invalid server entry. This
1282 fixes fatal bug when server has lost connection and will reconnect
1285 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Made some sanity checks to silc_server_daemonise like to check
1288 whether the requested user and group actually exists.
1290 * Added sanity check to SKE's silc_ske_responder_finish to check
1291 that the public and private key actually is valid.
1293 * Invalidate the client's nickname when receiving Replace ID
1294 packet and the Client ID is being replaced. This means that the
1295 server will query the nickname if someone needs it (client)
1298 * Sort the ID Cache in client library when the ID Cache data
1299 has changed (needs sorting).
1301 * Do not allow for SILC client to create several connections to
1302 several servers. The client does not support windows right now
1303 and generating multiple connections causes weird behaviour.
1305 Irssi-silc client does support windows and can handle several
1306 connections without problems, see: www.irssi.org and SILC plugin.
1308 * Fixed some places where client was added to the IDList. The
1309 rule of thumb is following (in order to get everything right):
1310 If the client is directly connected local client then the
1311 `connection' argument must be set and `router' argument must be
1312 NULL to silc_idlist_add_client function. If the client is not
1313 directly connected client then the `router' argument must
1314 bet set and the `connection' argument must be NULL to the
1315 silc_idlist_add_client function.
1317 * The funtion silc_server_packet_send_local_channel actually did
1318 not check whether the client was locally connected or not. It
1319 does that now. Fixed a bug related to LEAVE command.
1321 * Fixed Remove Channel User payload parsing bug in server's
1322 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1324 * The server's silc_server_save_channel_key now checks also the
1325 global ID list for the channel as it might not be in the local
1326 list. Fixed a bug related to LEAVE command.
1328 * Is this the end of the [<unknown>] buglet that has been lurking
1329 around for a long time? A little for loop fix in server's
1330 silc_server_command_whois_parse that is used by both IDENTIFY
1331 and WHOIS command. At least, this was a clear bug and a cause
1332 of one type of [<unknown>] buglet.
1334 * WHOIS and IDENTIFY commands call the function
1335 silc_server_command_[whois/identify]_check function even if
1336 we are not router server.
1338 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1340 * Added --with-gmp configuration option. If set the GMP
1341 is always compiled in the SILC source tree. If not set then
1342 it is checked whether the system has the GMP3 installed. If
1343 it has then the GMP won't be compiled (the system's headers
1344 and library is used), if it doesn't have it then the GMP is
1345 compiled in the SILC source tree.
1347 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Changed RSA private exponent generation to what PKCS #1
1350 suggests. We try to find the smallest possible d by doing
1351 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1352 not security fix but optimization.
1354 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Added new config entry [Identity] to fork the server and run
1357 it as specific user and group. A patch from Bostik.
1359 * Imported Dotconf configuration library into lib/dotconf.
1360 This will be used to create the SILC configuration files later.
1361 It will appear in the distsribution after this commit.
1363 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * A big code auditing weekend happening. Auditing code for
1366 obvious mistakes, bugs and errors. Also, removing any code
1369 Removed files for being obsolete:
1371 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1372 inline in the file lib/silcutil/silcbuffer.h)
1374 o lib/silcutil/silcbufutil.c (the header has inline versions)
1376 Changed code to fix possible error conditions:
1378 o The buffer formatting routines now check that the destination
1379 buffer really has enough space to add the data. This applies for
1380 both buffer formatting and unformatting
1381 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1382 unformatting was changed to accomodate following rules:
1383 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1384 sent to the function while XXX_*STRING will not allocate or copy
1385 the data into the buffer. Instead it sets the pointer from the
1386 buffer into the pointer sent as argument (XXX_*STRING used to
1387 require that the pointer must be allocated already). This change
1388 makes this whole thing a bit more consistent and more optimized
1389 (note that the data returned in the unformatting with XXX_*STRING
1390 must not be freed now). The routines return now -1 on error.
1392 o Tried to find all code that use buffer_format and buffer_unformat
1393 and added return value checking to prevent formatting and
1394 especially unformatting errors and possible subsequent fatal
1397 o Changed ske->x and ske->KEY to mallocated pointers in
1398 lib/silcske/silcske.h. Fixed possible data and memory leak.
1400 o Added return value checking to all *_parse* functions. Fixed
1401 many memory leaks as well.
1403 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1404 so that buffer overflows would not happen. All code now also
1405 checks the return value as it can fail.
1407 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Added reconnection support to server if the normal server looses
1410 its connection to the router (for example if router is rebooted).
1411 The server performs normal reconnection strategy implemented
1412 to the server. Affected file silcd/server.c.
1414 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Added new packet type SILC_PACKET_SET_MODE that is used to
1417 distribute the information about changed modes (for clients,
1418 channels and clients channel modes) to all routers in the
1419 network. Updated the protocol specification accordingly.
1421 Added functions into silcd/packet_send.c and
1422 silcd/packet_receive.c: silc_server_send_set_mode,
1423 silc_server_set_mode.
1425 Added new files silcmode.[ch] into lib/silccore that implements
1426 the encoding and decoding of Set Mode Payload. Added new type
1427 SilcSetModePayload. Moved the definitions of different modes
1428 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1430 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1432 * Oops, a little mistake in server's connection authentication
1433 protocol. The protocol is not ended with FAILURE but with
1434 SUCCESS if the authentication is Ok. :) Affected file is
1437 * Implemented NICK_CHANGE notify handling in server in the file
1438 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1439 the local clients on the channel. After the changing nickname
1440 in router environment snhould work and the [<unknown>] nickname
1441 should appear no more.
1443 The silc_server_replace_id function that receives the Replace ID
1444 payload now sends the NICK_CHANGE notify type also in the file
1445 silcd/packet_receive.c
1447 * Changed WHOIS and IDENTIFY command to support the maximum amount
1448 of arguments defined in protocol specs (3328 arguments). This
1449 fixed a bug that caused problems when there were more than three
1452 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Added extra parameter, command identifier, to the
1455 silc_client_send_command so that explicit command identifier
1458 Changed that ID list routines uses specific command identifier
1459 when sending WHOIS/IDENTIFY requests to the server so that they
1460 can be identified when the reply comes back.
1462 Affected files lib/silcclient/command.[ch],
1463 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1465 * Added `sender' argument to silc_server_packet_send_to_channel
1466 to indicaet the sender who originally sent the packet to us
1467 that we are now re-sending. Ignored if NULL. Affected file
1468 silcd/packet_send.[ch].
1470 * Added some server statistics support in silcd/server_internal.h
1471 SilcServerStatistics structure and around the server code. Also
1472 send some nice statistics information when client is connecting
1475 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Fixed channel ID decoding in server's JOIN command reply in
1478 silcd/command_reply.c
1480 * Fixed braodcasting of replace ID payload to not to send it if
1481 we are standalone server in silcd/packet_receive.c.
1483 * Fixed all channel message sending routines to not to send
1484 packets to clients that has router set, since they are routed
1485 separately in the same function earlier. Affects file
1486 silcd/packet_send.c and all channel packet sending functions.
1488 * In USERS reply, res_argv[i] are not allocated, the table
1489 is allocated. Thus changed that free the table, not its
1492 * In server's whois_check and identify_check if the client is
1493 locally connected do not send any WHOIS commands - they are not
1496 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Fixed some minor bugs in client when sending WHOIS command. The
1499 arguments was in wrong order.
1501 * Removed statis function add_to_channel from server in
1502 silcd/command.c that was previously used with the joining but
1505 * Tested USERS command in router environment successfully with two
1506 routers, two servers and two clients.
1508 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Reorganized the USERS command and command reply in client library
1511 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1512 When the command is given by user we register a pending command
1513 callback that will reprocess the command after the reply has been
1514 received from the server. When reprocessing the packet we then
1515 display the information. Thus, the USERS information is displayed
1516 now in the command callback instead of in the command reply
1517 callback. The processing of the command is same as previously
1518 when server has sent the command reply in the JOINing process.
1520 * Added to USERS command in silcd/command_reply.c to join the client,
1521 we didn't use to know about, to the channel after we've created
1522 a client entry for it. Also, for clienet we did know already still
1523 check whether it is on the channel or not and add it if not.
1525 * Removed silc_server_command_join_notify as the function and its
1528 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Changed the client's pending command handling to the same as the
1531 server's pending command handling. It is also now possible to
1532 execute command reply functions from other command reply
1533 function as the function callbacks for commands and command
1534 replies are one and same. The pending commands are not static
1535 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1536 in client connection context. Thus, pending commands are server
1537 connection specific as it is convenient.
1539 Changed the function silc_client_command_pending and
1540 silc_client_command_pending_del and added new function
1541 silc_client_command_pending_check. Removed the
1542 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1545 * Added cmd_ident, current command identifier, to the client
1546 connection context in lib/silcclient/client.h to keep track on
1547 command identifiers used in command sending. Client's command reply
1548 function handling now supports the mandatory command identifiers.
1550 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1551 funtions in client to fully support pending command callbacks.
1553 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1554 as one of the arguments to the application in the command reply
1557 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1558 before first releasing SILC but came back. Now it is removed again
1559 and should come back nomore. The FORWARDED flag was used only
1560 by the JOINing procedure by forwarding the command packet to router.
1561 Now, the JOINing procedure has been changed to more generic (due
1562 to various router environment issues) and FORWARDED is not needed
1563 anymore for anything. The protocol specification is yet to be
1566 Now, removed silc_server_packet_forward from server and the flag
1567 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1569 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Renamed NAMES command to USERS command. The NAMES was named that
1572 due to historical reasons. Now it is renamed. Also, rewrote
1573 parts of the USERS command. The nickname list is not sent anymore
1574 by the server. Only Client ID and mode lists are sent in the USERS
1575 command. Changed this also to the protocol specification.
1577 The client now resolves the names and stuff after it receives
1578 the USERS list from the server when joining to the channel.
1580 * WHOIS and IDENTIFY commands has been changed to support multiple
1581 Client ID's per command. One can now search for multiple users
1582 in the network by sending only one WHOIS or IDENTIFY command.
1583 Changed the code and the protocol specifications.
1585 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1586 uses silc_server_command_whois_parse to parse the request. */
1588 * If normal server, do not parse the WHOIS and IDENTIFY requests
1589 before sending it to the router. Saves some time.
1591 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Fixed JOIN command on client library. Wrong number of arguments
1594 used to crash the client.
1596 * Added silc_server_channel_has_global function to check whether
1597 channel has global users or not.
1599 * Added silc_server_channel_has_local function to check whether channel
1600 has locally connected clients on the channel.
1602 * The silc_server_remove_from_one_channel now checks whether the
1603 channel has global users or not after given client was removed from
1604 the channel. It also checks whether the channel has local clients
1605 on the channel anymore. If it does not have then the channel entry
1606 is removed as it is not needed anymore.
1608 * The silc_server_notify now checks on JOIN notify whether the joining
1609 client is one of locally connected or global. If it is global then
1610 the channel has now global users on the channel and that is marked
1611 to the channel entry. Also, it now saves the global client to
1612 global list who is joining and JOINs it to the channel. This is
1613 for normal server, that is.
1615 Changed silc_server_send_notify_on_channel,
1616 silc_server_packet_relay_to_channel and
1617 silc_server_packet_send_to_channel check if we are normal server
1618 and client has router set (ie. global client) do not send the
1619 message to that client, as it is already routed to our router.
1621 * Implemented LEAVE notify type handling in silc_server_notify
1624 * Tested LEAVE command in router environment successfully. Tested
1625 with two routers, two servers and two clients.
1629 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1631 * Implemented SIGNOFF notify type handling in silc_server_notify
1634 * silc_server_remove_id now removes the client entry from all channels
1635 it has joined and thusly sends SIGNOFF notify type.
1637 * Rewrote the NAMES list generation in server by removing two excess
1638 loops. The lists are created now inside one loop.
1640 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * silc_server_remove_channel_user checks now also global list
1643 for channel and client.
1645 * silc_server_new_channel_user checks now both local and global
1646 list for channel and client. Fixed a bug in client id decoding.
1647 Used to decode wrong buffer.
1649 * silc_server_channel_message checks now both local and global
1650 list for channel entry.
1652 * Tested channel joining (hence JOIN) in router environment
1653 successfully. Tested with two routers, two servers and two
1656 * Tested channel message sending in router environment successfully.
1658 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Added silc_server_save_channel_key into server.[ch] to save the
1661 received channel key in Channel Key payload processing. It is
1662 also used in JOIN command reply handling.
1664 Equivalent function silc_client_save_channel_key added into
1665 client.[ch] into client library.
1667 * Changed JOIN command reply to send information whether the channel
1668 was created or not (is existing already) and the channel key
1669 payload. Changed protocol specs accordingly.
1671 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1672 the request was sent by ID and not by nickname. Crashed on
1675 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1678 now correctly save the received data.
1680 * silc_server_free_sock_user_data now notifies routers in the
1681 network about entities leaving the network.
1683 At the same time implemented functions silc_server_remove_id
1684 and silc_server_send_remove_id to receive and send REMOVE_ID
1685 packets. The packet is used to notify routers in the network
1686 about leaving entities. The ID removed will become invalid in
1689 * Added function silc_idlist_del_server into server. Removes and
1690 free's server entry from ID list.
1692 * silc_server_private_message function now checks, if we are router,
1693 that the destination ID really is valid ID, naturally.
1695 * In router when NEW_ID packet is received (for new client) the
1696 hash of the Client ID is saved in the ID Cache but the
1697 client->nickname is set to NULL, instead of putting the hash
1700 IDENTIFY command now also checks that client->nickname must be
1701 valid. If it is not if will request the data from the server who
1702 owns the client. Added new function
1703 silc_server_command_identify_check.
1705 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1706 to set the command to already allocated Command Payload.
1708 * Tested private message sending in router environment with two
1709 routers, two servers and two clients. Fixed minor bugs and now
1712 * Fixed segfault from client's NAMES command. Used to crash if
1715 * Forwarded packets must not be routed even if it is not destined
1716 to the receiver. Changed server code comply with this.
1718 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added `require_reverse_mapping' boolean value to ServerParams
1721 structure. If TRUE (not default) the server will require that
1722 the connecting host has fully qualified domain name.
1724 If the reverse mapping is not required and hostname could not be
1725 found the IP address is used as hostname.
1727 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Implemented version string checking to both client and server.
1730 The check is incomplete currently due to the abnormal version
1731 strings used in development version of SILC.
1733 * Changed all command functions in server to use the new
1736 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * Changed char *data to unsigned char *data in ID Cache system to
1739 support binary data as ID Cache data. Changed code to support
1740 binary data in lib/silccore/idcache.c.
1742 * Renamed silc_server_packet_relay_command_reply to
1743 silc_server_command_reply as it is normal packet receiving
1744 function. Rewrote the function to accept command replys for
1745 servers and not only for clients.
1747 * Mark remote router always as registered server if we are connecting
1748 to it. Otherwise, commands sent by the router to us are ignored.
1750 * All ID List find routines now returns the ID Cache Entry pointer
1751 as well if requested.
1753 * WHOIS command works now in router environment, tested with two
1754 routers, two servers and two clients.
1756 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1757 in router environment (as it is almost equivalent to WHOIS) but
1758 hasn't been tested thoroughly. Added new functions:
1760 silc_server_command_identify_parse
1761 silc_server_command_identify_send_reply
1762 silc_server_command_identify_from_client
1763 silc_server_command_identify_from_server
1765 * Disabled route cache adding because adding two different ID's with
1766 same IP replaces the old cache entry thus giving wrong route.
1767 The entry->router->connection is always the fastest route anyway
1768 so route cache may not be needed. Of course, new routes maybe
1769 established after receiving the ID when the entry->router->connection
1770 might not be anymore the most optimal.
1772 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Add route cache for received ID for fast routing.
1776 * Added silc_server_packet_route to route received packet on router
1777 that is not destined to us.
1779 * Renamed silc_server_get_route to silc_server_route_get.
1781 * Added id_string and id_string_len fields into SilcServer to
1782 include encoded ServerID for fast comparing without excess
1783 encoding of the ID's.
1785 * Cleaned up WHOIS command on server side. Added following static
1788 silc_server_command_whois_parse
1789 silc_server_command_whois_check
1790 silc_server_command_whois_send_reply
1791 silc_server_command_whois_from_client
1792 silc_server_command_whois_from_server
1794 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1795 arguments in command replies. All command functions should be
1796 updated to use this macro.
1798 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Minor typo fixes on command reply handling on server.
1802 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1804 * Added silc_server_command_add_to_channel internal routine to add
1805 the client to the channel after router has created the channel and
1806 sent command reply to the server.
1808 * Added generic silc_server_send_command to send any command from
1811 * Use static buffer with ID rendering instead of duplicating data.
1813 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Fixed a channel user mode bug when joining to a channel server gave
1816 everybody channel founder rights, oops.
1818 * We mark ourselves as the router of the incoming server connection
1819 if we are router ourselves. This way we can check in some packet
1820 sending functions whether it is locally connected server. For
1821 incoming router connections we put NULL.
1823 * For router sending packets locally means now always sending the
1824 packet cell wide; to local clients and local servers. For normal
1825 server sending packet locally means sending it to only local
1828 * Fixed the JOIN command to really work in router environment. If the
1829 channel is created it is always created by the router. Router is
1830 also responsible of making the initial joining to the channel,
1831 sending JOIN notify to the sending server and distributing
1832 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1833 does not exist server doesn't do anything else but forward the
1834 command to the router which performs everything.
1836 * Added silc_server_send_channel_key function to send the Channel Key
1839 * Added silc_server_create_channel_key to create new channel key. The
1840 channel key is now re-generated everytime someone joins or leaves
1841 a channel, as protocol dictates. Note: channel->key_len is the
1844 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1847 packet_receive.[ch] to separate packet sending and receiving
1848 routines. The server.[ch] now includes everything else including
1849 actual packet processing (writing and reading data) and other
1852 Renamed silc_server_private_message_send_internal to
1853 silc_server_send_private_message. The routine is still though
1854 used only to relay private messages as server does not send
1855 private messages itself.
1857 Renamed silc_server_new_channel to silc_server_create_new_channel
1858 and added new function sicl_server_new_channel that handles the
1859 incoming New Channel packet. Added also new sending function
1860 silc_server_send_new_channel to send New Channel Payload.
1862 * Added new function silc_server_notify to process incoming notify
1863 packet to the server/router. Server may then relay the notify
1864 to clients if needed.
1866 * Added new function silc_server_new_channel_user to process incoming
1867 New Channel User packet. Router will redistribute the packet and
1868 send JOIN notify to its local clients and locally connected servers
1869 if needed. Normal server will send JOIN notify to its local client
1870 on same channel when received this packet. Added also corresponding
1871 sending function silc_server_send_new_channel_user to sent the
1874 * Added boolean route argument to send_notif_to_channel and
1875 packet_send_to_channel functions to attempt to route the packet
1876 if it is TRUE and send only locally if it is FALSE.
1878 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * silc_server_replace_id now broadcasts the received replace ID
1881 packet if it is not broadcast packet already. The router must
1882 broadcast to inform other routers about changed ID.
1884 * Added backpointer to server's router into SilcServer context in
1885 silcd/server_internal.h.
1887 * Fixed silc_server_packet_broadcast to send correct broadcast
1890 * The channel key is now distributed to the local client as soon
1891 as it is received from the router (in router environment) so that
1892 no other packet may be sent for the channel until client has
1895 * silc_server_remove_channel_user now broadcasts the received
1896 Remove Channel User packet if it is not broadcast packet already.
1897 The router must broadcast to inform other routers about removed
1900 * Added users field into SilcPacketContext that is a reference count
1901 of the context. One can increase the reference count by calling
1902 silc_packet_context_dup which is now changed to just increase the
1903 reference count instead of duplicating the data. The reference
1904 count is decresed by calling silc_packet_context_free that will
1905 free the data after the reference count hits zero.
1907 For now on the packet context and everything allocated into it
1908 (including the raw packet from network) must be freed by calling
1909 the new silc_packet_context_free function. Added also new function
1910 silc_packet_context_alloc that must be used now to allocate the
1911 context. This also means that if a routine is asynchronous from
1912 silc_[client/server]_packet_parse_type the packet context must
1913 be duplicated by calling silc_packet_context_dup. Otherwise it
1914 gets free'd after silc_[client/server]_packet_parse_type returns.
1915 Also, one must remember that if packet is duplicated then its
1916 reference count must be decresed by calling the free function as
1917 many times as it was duplicated.
1919 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1920 from both client and server.
1922 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Made joining to a channel working in router environment.
1926 * Cleaned up JOIN command on server side and create function
1927 silc_server_command_join_channel internal routine to make the
1930 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Changed silc_command_pending list to SilcDList. Also, added
1933 `ident' field to SilcServerCommandPending structure to identify
1934 the reply and to call correct callback.
1936 Added silc_server_command_pending_check function to replace the
1937 corresnponding macro. The silc_command_pending list is not
1940 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1941 to set identifier to previously allocated Command Payload. It
1942 is used to set identifier for command when resending Command
1945 * Added silc_command_payload_encode_payload to encode Command
1946 Payload buffer from SilcCommandPayload structure.
1948 * Added silc_argument_payload_encode_payload to encode Argument
1949 payload buffer from SilcArgumentPayload structure.
1951 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Changed WHOIS command to support router connection on server side.
1954 The whois request is always sent to router unless the server is
1955 standalone server. After server has received the reply from the
1956 router will it send the reply to the client.
1958 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1959 broadcast received broadcast packet. The function is used only
1960 by router. The broadcast packet is always sent to the router's
1963 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1964 render given ID to printable string, for log files for example.
1966 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Made basic router to router connections working. At least they
1969 can now connect to each other but nothing really works the way
1970 they are supposed - yet.
1972 * Added new initiator token to RouterConnection configuration
1973 file in silcd/serverconfig.[ch]. It is used to tell whether we
1974 are the initiator to the remote router or whether we'll expect
1975 the other end to connect.
1977 * Moved registering of listener task to silc_server_init, hence
1978 the server starts listenning as soon as it is run, even if it
1979 does not have connections to other routers. Let's see how well
1982 * Changed default connection retry timeouts for more suitable in
1985 * Removed cipher and such arguments from silc_idlist_add_client
1986 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1987 Added new function silc_idlist_add_data to add the keys and stuff
1990 * Added SilcIDListData structure and added it to SilcClientEntry
1991 and SilcServerEntry as their first field in the structure. This
1992 way we can explicitly cast the ID entries to the SilcIDListData
1993 structure and get common data for the entries. In past, we had
1994 to first check what type of connection it is and then cast it to
1995 correct ID entry type. Now, we can directly cast the opaque
1996 pointer to the SilcIDListData (no matter what ID entry it actually
1997 is) and get the data needed.
1999 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2002 in some circumstances even if threre were timeout tasks, though not
2003 IO tasks, but tasks anyway. Now fixed.
2005 * Defined SilcServerConnection structure to hold connection specific
2006 stuff about directly connected servers and routers. The definition
2007 is currently in silcd/server_internal.h. I thought about having
2008 a bit more important role fro this struct but for now it is used
2009 only when connecting to other server (or router actually).
2011 * Added connecting retry support in server when connecting to
2012 router(s). The retry feature implement exponential backoff
2013 algorithm. Also, added SilcServerParams structure to hold default
2014 parameters for server. For now, it include these retry settings
2015 and are hard coded. After server is moded to be as Silc Server
2016 Library this structure will be more important.
2018 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Changed client librarys channel->clients table to SilcList and
2021 changed code accordingly.
2023 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Changed client's channel table to SilcList and changed code
2026 accordingly. Also changed SilcChannelClientEntry to include back-
2027 pointer to the channel so that client entry can use that structure
2028 as list as well and we have fast cross-reference to the channel.
2029 This change dramatically decreased the complexity of channel
2030 handling with client entry and vice versa (removed one extra
2031 loop when searching for channel entry from many functions).
2033 * Changed server->sim from table to SilcDList and changed code
2036 * NAMES command can now be used from user interface. It will show
2037 the user list on the channel, neatly.
2039 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2040 Code now saves realname of the user if it becomes available.
2042 * Renamed configure.in to configure.in.pre and made ./prepare
2043 script to automatically add correct version string to
2044 configure.in which it creates from configure.in.pre.
2046 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * NAMES command reply now shows users mode with the nickname when
2051 * Moved silc_client_ch[u]mode[_char] functions from
2052 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2053 place sucks, they are utility functions and should be in some
2056 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2058 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2061 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Added TRQ (efficient deque and list library) into lib/trq. This is
2066 a very good list library that is currently used in the SILC. Defined
2067 SilcList API over the library because I didn't like the API very
2068 much. See lib/trq/silclist.h for the API and examples of how to
2069 use the API. Fixed various places in the code to use the new
2070 SilcList API. The SilcList is meant for lists that has a structure
2071 already defined as a list. It is not suitable to add just some
2072 context to the list (in TRQ, the context is the list actually).
2074 So, I defined SilcDList that can be used for the purpose where
2075 predefined list structure does not exit. This can be used as
2076 such list. Now some context just can be added to the SilcDList.
2077 Currently this list is not used in the SILC just yet, though there
2078 are a lot places where this can replace dynamically allocated
2079 tables and I will fix these places, later, to use SilcDList.
2080 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2081 and use TRQ internally).
2083 Also fixed some annoying warning messages that the original TRQ
2084 code generated. Also minor changes to TRQ's Makefile.in.
2086 * Added support for querying by Client ID to both WHOIS and
2087 IDENTIFY commands into server, as required by the protocol.
2089 * Removed method function pointers from SilcBuffer structure. They
2090 weren't used to anything and just increased the context size for
2091 no good reason. This change also made silc_buffer_alloc and
2092 silc_buffer_free functions inline functions.
2094 * Disabled command flooding detection support until it's fixed so
2095 that it accepts commands in but does not execute them more than once
2098 * Added silc_net_localhost(), to return local hostname, into
2099 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2100 that must be initialized before calling silc_client_init.
2102 * Added new function: silc_server_send_notify_on_channels to send
2103 notify messages to all channels client has joined. It is assured
2104 that the message is sent only once per client.
2106 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2107 lib/silcutil/silcutil.[ch] as silc_format function. The new
2108 function is generic and is used by server as well, not only by
2109 the logging routines.
2111 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2112 the provided version string was not acceptable. Added new function:
2113 silc_ske_check_version into lib/silcske/silcske.h. The function
2114 must be implemented by the application (client or server) and it
2115 does not reside in the SKE library. The function checks the version
2116 string remote end sent.
2118 * Added back pointers (to opaque context and to SilcSocketConnection)
2119 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2121 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2122 duplicate packet context structure.
2124 * Changed `notify' client operation to send same arguments as client
2125 receives from server except for ID's. ID's are mapped to correct
2126 ID entry and that is returned. Also, if channel entry is not sent
2127 by server but the notify is for channel the channel entry is sent
2128 to application (otherwise application doesn't know that it is for
2129 channel (library gets it from packet's Destination ID)).
2131 * Added silc_client_remove_from_channels into client library to
2132 remove a client from all channels it has joined to. Used when
2133 received SIGNOFF notify from server. Added also new function
2134 silc_client_replace_from_channels to replace old ID entry with
2135 new ID entry on all channels. Used when received NICK_CHANGE
2138 * Fixed ID Cache list handling in silc_idlist_get_client in
2139 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2140 to get (or query) client by ID.
2142 * Updated TODO list.
2144 * Added connection authentication status message defined by the
2145 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2146 support for these into the code in client and server side.
2148 * Added generic function silc_client_send_command to send any command
2149 with variable argument list. Application should use this function
2150 to send commands if the command functions provided by the library
2151 does not suite for the application's user interface needs.
2153 * Added new `failure' client operation. Application is notified about
2154 received failure packet if client is executing a protocol. In this
2155 case the protocol's execution has failed.
2157 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2158 is required by the protocol.
2160 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2161 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2164 * Added status flag to SilcSKE object to indicate realtime status
2165 of the SKE protocol.
2167 * Application receives now exactly same command reply arguments as
2168 the library receives from server. However, if ID is received the
2169 corresponding ID entry is returned to the application (eg. Client
2170 ID is mapped to correct SilcClientEntry entry and that is returned).
2171 Changed command_reply client operation due to this change.
2173 * Changed all ID's in commands and in command replys as ID Payloads.
2174 Change affected both client and server side codes.
2176 All ID's sent in SILC network (with execption of ID's in SILC
2177 Packet header) are sent in ID Payload to support variable length
2180 * Server now notifies nick changes and notifies all clients on
2181 the channels about the new nickname (about the new Client ID,
2184 * Implemented CMODE command to change channel modes. Supports all
2185 channel modes defined by the protocol specs except ban and invite
2186 lists. (Also, private channel key mode is supported but support for
2187 setting private channel key in client is missing, thus, this mode
2188 has no effect on client side (except that server requires that the
2189 client uses private channel key and normal channel traffic does not
2192 Also, invite mode works per se, but INVITE command does not work
2193 yet correctly, so you can set channel as invite only channel but
2194 inviting clients to the channel does not work (it is yet to be
2195 thought what's the best way to do it).
2197 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2198 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2199 Implemented CUMODE command to change user's mode on the channel.
2200 Supports all modes defined by the protocol specs.
2202 * Added NAMES command reply to return users modes on the channel.
2204 * Removed unnecessary and slow ciphers from lib/silccrypt.
2206 * Set SO_KEEPALIVE option to connection sockets by default.
2208 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2210 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2211 redefined the Notify Payload into protocol specs.
2213 * Added silc_id_payload_parse_id to get ID directly from raw
2216 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2219 accept searching by Client ID as well.
2221 * Added support for LEAVE and SIGNOFF notify types in client library.
2223 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2224 to parse ID Payload from raw data.
2226 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Added flags parameter into silc_ske_assemble_security_properties
2229 function in lib/silcske/silcske.[ch].
2231 * Changed notify client operation to fit better for notify messages
2232 sent by server. The notify payload received from server is now
2233 passed to the application (after parsing it to SilcNotifyPayload).
2234 It is application's responsibility to retrieve the arguments
2235 from the payload and show the message the way it wants. The message
2236 sent by server is implementation specific.
2238 * Changed public keys to comply with the protocol specification.
2239 Old public keys are not supported anymore and are not compatible.
2241 * Removed nickname from Channel Payload as the latest draft removed
2242 it. The client must resolve the nickname from the NAMES command
2243 reply received when it joined the channel.
2245 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2247 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Fixed some errors in protocol specification drafts.
2251 * Created lib/silccore/silcnotify.c to implement Notify Payload
2252 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2253 generic payloads described by protocol specifications. The file
2254 includes implementations for ID Payload and Argument Payload.
2256 * Changed Command Payload implementation to use the new Argument
2257 Payload. Changed command_xxxx_payload to command_payload_xxxx
2258 to comply with SILC coding conventions.
2260 * Added suppport for Argument Payload handling in Notify Payload
2261 implementation as protocol requires it. Added the new support
2262 into server and client lib as well.
2264 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Added support for multiple nicknames on same channel. [n] is
2267 added locally to the nickname if there are more than one same
2268 nicknames on the channel.
2270 * Server now sends all nicknames that matched WHOIS request.
2271 Client also shows the list received from server.
2273 * Added TOPIC command to client side. User can now set and show
2274 current topic on channel.
2276 * Added MOTD command to client and server. Also, server sends the
2277 motd when client connects to the server.
2279 * Changed version strings to comply ISO 8601.
2281 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Fixed protocol error handling in client library. It should now
2284 cope even if the SKE fails for some reason.
2286 * Made new protocol specification drafts for submitting to IETF.
2288 * Implemented TOPIC command to server in silcd/command.c.
2290 * Added two new notify types into lib/silccore/silcnotify.h:
2291 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2292 notify nickname change and topic setting/change on a channel.
2294 * API change of command_reply operation in client library. The
2295 application gets now the status type received from server as well.
2297 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2301 * Cras fixed and optimized the packet handling even further and
2302 it should work now. Minor change to the prototype of function
2303 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2305 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Added new function into lib/silcutil/silcschedule.[ch]:
2308 silc_schedule_with_fd to select() a specified fd. The function
2309 returns after timeout expires or data arrives or goes. The
2310 function is used by packet routines to wait that all data is
2311 received from network.
2313 * Fixed data reading from network in lib/silccore/silcpacket.c.
2314 The code now assures that all data is read from the fd and then
2315 continues packet processing. This was a bug fix since the code
2316 used to drop some data in some circumstances.
2318 * Added new function into lib/silcclient/client.[ch]:
2319 silc_client_start_key_exchange to start key exchange after
2320 connection has been established to server. The code internally
2321 now uses this funtion but its main purpose was to provide it
2322 for applications that perform their own connecting. After
2323 application has created a connection it merely calls this
2324 function to start the key exchange between client and server.
2325 The library takes care of everything else after that.
2327 Updated also lib/silcclient/README to explain the usage of
2330 * Do not send to application information that connection has
2331 been established. Application gets notified it by connect
2334 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Applied cras's patch to add silc_schedule_one function. The
2337 function runs scheduler once and returns.
2339 * Fixed the scheduler after cras messed it up. The timeout
2340 handling works now as it's supposed to work.
2342 * Added into lib/silccore/ silcnotify.h to include notify
2343 message types support. Changed silc_server_send_notify*
2344 functions, in server.[ch], to support those new notify types.
2345 Added the support for the notify types into client library,
2346 as well. Added new notify client operation into ops.h in
2349 * Changed silc_server_packet_send_to_channel to send normal
2350 packets instead of just channel message packets. The function
2351 is now used to send the notify packets to channels. It is not
2352 used to send channel message packets anymore, as server never
2355 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2356 va_arg()s as it seems to require it nowadays. I guess, if SILC
2357 is compiled with older va_arg() the new code should work anyway.
2359 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Splitted core library. Core library (lib/silccore) includes
2362 now only SILC protocol specific core (and common) components.
2363 Created new utility library (lib/silcutil) that includes more
2364 generic purpose stuff. The stuff for util library was taken
2365 from the old core library. This was minor and easy split.
2367 * Created SILC Client Library (lib/silcclient) that includes
2368 implementation of the SILC client without user interface. This
2369 was major move from silc/ directory. The code has been changed
2370 so that it is transparent towards the user interface. The
2371 silc/ directory includes now the same user interface as before
2372 and it uses the new client library. Read lib/silcclient/README.
2373 Basicly, the client library performs everything else related
2374 to SILC except user interface handling. Also, configuration
2375 files are considered to be part of user interface and library
2376 does not handle them.
2378 This change also changed a lot of structures, function naming etc.
2379 Most important change was that SilcClientWindow object was
2380 renamed to SilcClientConnection in the client library. Created
2381 also new file lib/silcclient/ops.h. Also added new files
2382 silc/local_command.[ch] and silc/client_ops.[ch].
2384 All these changes were made to make it easier for user interface
2385 designers to create what ever user interface for the SILC client
2388 It is also expected that the server will be moved to lib
2389 directory as well and SILC Server Library will be created;
2390 sometimes in the future.
2392 * Removed Local commands from lib/silccore/silccommand.h as
2393 they are application specific and new client library does not
2394 handle any of those anymore.
2396 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2397 old client implementation in silc/.
2399 * Added support for callback functions in SILC_LOG_* macros.
2400 Application can now set its own callbacks that will be called
2401 instead of using the default functions that will always print
2402 the debug messages to stderr (or stdout). Also, debugging can
2403 now be disabled by setting silc_debug to FALSE and re-enabled by
2404 setting it to TRUE. Note, that logging will still work even
2405 if debugging is disabled.
2407 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2408 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2409 silc_log_reset_debug_callbacks.
2411 * To enable debugging in silc client one must give now -d
2412 option on command line.
2414 * Changed silc_schedule_init to automatically allocate task queues
2415 if they are not allocated before calling it.
2417 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Added GMP 3.1 into math library.
2421 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2424 a channel in SILC network. The packet is used by servers and
2425 routers to notify other routers that user has left a channel.
2426 This little feature was missing until now. Added the feature
2427 to protocol specification as well.
2429 Added functions: silc_server_send_remove_channel_user and
2430 silc_server_remove_channel_user into server.[ch].
2432 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2433 lib/silccore/silcpacket.h. However, they are not implemented
2436 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Fixed joining to a channel and sending channel messages
2439 between server and router. The channel message sending should
2440 now work inside a cell.
2442 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Fixed the private message sending between server and router.
2445 The private message sending should now work inside a cell.
2447 * Added silc_server_replace_id into server.[ch] to replace
2448 existing ID in the SILC network.
2450 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2451 and silc_idlist_replace_server_id into idlist.[ch] in server.
2453 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Fixed the server to server connections. Server can again now
2456 connect to router. Router to router connections probably does
2459 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Added dynamic protocol registering support. Now protocols can
2462 registered and unregistered on the fly. Patch by cras.
2464 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Added lib/contrib directory to hold routines that some platforms
2467 don't have but are needed by SILC.
2469 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2470 into lin/contrib to provide getopt() and getopt_long() for
2471 those who don't have it.
2473 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added AWAY command to client. When away message is set and
2476 client receives a private message packet the client automatically
2477 replies to the sender with the away message.
2479 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2480 bug seemed to be the cause of recent problems when compiling
2483 * Added version detection support to SKE protocol specification
2484 and added the new changes to the SKE implementation as well.
2485 There were other minor changes in the SKE protocol as well.
2487 Many changes in lib/silcske/silcske.[ch] and in
2488 lib/silcske/payload.[ch].
2490 * Added ^U functionality, clear input line. Patch from cras.
2492 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Mainly small bugfixes on core library. Fixed some debugging
2495 logging and buffer overflow in silclog.c.
2497 * Updated config.sub and config.guess on the distribution tree.
2499 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added command lagging support in server. Client may execute
2502 commands now only once in two seconds.
2504 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Optimized packet reception. MAC computation and checking is now
2507 also more optimized. A lot previously duplicated code is now
2508 used as generic by both client and server.
2510 * Fixed key pair generation in clientutil.c
2512 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added into lib/silccore/silcbufutil.[ch] new function;
2515 silc_buffer_realloc.
2517 * Moved generic packet sending/encryption functions to
2518 lib/silccore/silcpacket.[ch] from client and server. Some
2519 rewriting of the functions.
2521 * Moved all generic packet reception/decryption functions to
2522 lib/silccore/silcpacket.[ch] from client and server. The
2523 packet processing is now much cleaner in both client and server.
2524 These were major changes in both client and server.
2526 * Created many common functions in server to do packet sending.
2527 Previously code were duplicated a lot, this has been removed
2530 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Rewrote major parts of the ID cache system. Don't know
2533 whether it is better now or not but at least the API is more
2536 * Major rewrite on ID cache stuff on client because of the ID
2537 cache API changes. Added idlist.c to client.
2539 * Also major rewrite on ID cache stuff on server as well.
2540 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2541 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2542 in hand, instead they are all put into the ID cache system now.
2543 All server_idlist_* routines uses ID cache now instead of
2544 traversing its own lists (those lists does not exist anymore).
2545 SilcIDList though still exists. Also, SilcXXXEntry's are
2548 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Finally made the SKE implementation compliant to the protocol
2551 specification. All mp integers are now binary encoded as
2552 opposed being HEX encoded.
2554 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2557 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2558 functions: silc_[encode/decode]_pem. Also added function
2559 silc_encode_pem_file to PEM encode with newlines ('\n') for
2562 * SILC public keys are now encoded either PEM or binary. Same
2563 option is for private keys as well. By default private keys
2564 are binary encoded and public keys PEM encoded. Silly HEX
2565 encoding were removed.
2567 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2568 function to create fingerprints.
2570 * Fixed a bug in SHA1; does not change the original data anymore.
2572 * Partly implemented INFO command on client and server side.
2573 Fixed CLEAR command. Changes to SERVER command; show current
2574 server(s) when giving command without arguments. Added
2575 VERSION command to client.
2577 * Added check to server that unregistered connections cannot
2578 execute commands (unless it is specificly allowed).
2580 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Fixed screen refresh.
2584 * Fixed channel joining bug from client. On some circumstances
2585 client tried to join to a channel it had already joined.
2587 * Added public key verification process into client's protocol.c.
2588 The client now verifies the public key from user and saves
2589 it into ~./silc/serverkeys/ directory.
2591 Added into: clientutil.[ch]: silc_client_verify_server_key.
2593 * Changed SKE protocol's silc_ske_initiator_finish function
2594 to accept callback function that verifies the received public
2595 key. Removed old silc_ske_verify_public_key function.
2597 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2600 silc_pkcs_private_key[_data]_set.
2602 * Made the password and public authentication more cleaner in
2603 server's protocol.c.
2605 * Removed historic and obsolete protocol `channel_auth' from
2606 both client and server.
2608 * Removed wrong way of sending command status messages from
2609 server to client in server's command.c. The old way violated
2610 protocol specification.
2612 Changes to silccore/silccommand.[ch]: removed
2613 silc_command_encode_status_payload -> not needed anymore,
2614 changed silc_command_encode_payload_va to accept extra
2615 argument on variable argument list. The argument type must
2616 now be provided to the function. Also, added new function:
2617 silc_command_encode_reply_payload_va which is same as
2618 normal command_encode_payload_va except command status type
2619 is provided as extra argument.
2621 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Added ~./silc directory handling. The directory includes the
2624 public and private keys for the client.
2626 Added silc_client_check_silc_dir, silc_client_create_identifier
2627 and silc_client_load_keys.
2629 * Implemented SILC protocol compliant public key. Added public
2630 and private key saving to and loading from files.
2632 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2633 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2634 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2635 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2636 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2638 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2639 silc_pkcs_load_[public/private]_key.
2641 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Added silc_server_get_route (route.[ch]) to get connection
2644 data for the fastest route for given ID.
2646 * Implemented INVITE command on client and server. The command
2647 were re-defined in the SILC Protocol Specification and the
2648 implementation now complies with the specification.
2650 * Implemented PING command on client and server.
2652 * Implemented NAMES command on client and server. The server side
2653 supports currently only normal server not router server yet.
2654 Some changes to NAMES definition in SILC protocol specification.
2656 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Implemented LEAVE command on client and server.
2660 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2661 again. This change was made to the protocol as well. Server
2662 should not violate the protocol specification anymore.
2664 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2667 was tested. SOCKS4 was not but should work anyway.
