1 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented the BAN command to the client library.
5 * The JOIN command in the server now checks the invite list
8 * Changed the silc_command_reply_payload_encode_va and the
9 silc_command_payload_encode_va to support that if argument is
10 NULL it ignores and checks the next argument. Affected file
11 lib/silccore/silccommand.c.
13 * Added silc_server_send_notify_ban to send the BAN notify
16 * Chaned the silc_notify_payload_encode to support that if
17 argument is NULL it ignores and checks the next argument.
18 Affected file lib/silccore/silcnotify.c.
20 * Tested ban lists in router environment successfully.
22 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Implemented BAN command to the server, in silcd/command.[ch].
26 * Removed the BAN and INVITE_LIST modes from the CMODE command
29 * Added function silc_string_match to regex match two strings.
30 Affected files lib/silcutil/silcutil.[ch].
32 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Redefined parts of the SilcChannelEntry in the server to support
35 the new ban and invite lists.
37 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Redefined the INVITE command. The same command can be used to
40 invite individuals to the channel but also to manage the invite
41 list of the channel (to add to and remove from the invite list).
42 Updated the protocol specs.
44 * Added new command SILC_COMMAND_BAN that can be used to manage
45 the ban list of the channel. Updated the protocol specs.
47 * Removed the channel modes: the SILC_CMODE_BAN and the
48 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
49 in the CMODE command. The equivalent features are now available
50 using INVITE and BAN commands. Updated the protocol specs.
52 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
53 in the network about change in the current ban list. The notify
54 type is not used by the client.
56 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
57 support the invite lists.
59 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Added new function silc_string_regexify that converts string
62 including wildcard characters into regex string that can
63 be used by the GNU regex library. Added into the file
64 lib/silcutil/silcutil.[ch].
66 Added silc_string_regex_combine to combine to regex strings
67 into one so that they can be used as one regex string by
68 the GNU regex library. Added into the file
69 lib/silcutil/silcutil.[ch].
71 Added silc_string_regex_match to match two strings. It returns
72 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
74 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Imported GNU regex to the soruce tree into lib/contrib.
77 Fixed some compiler warning from the regex.c.
79 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Fixed MOTD command in the server to work in router environment.
83 * Fixed the MOTD command in the client library to support
84 the server argument in the command.
86 * Added `nickname_len' argument to the silc_idlist_add_client
87 in the server, as the `nickname' argument may be binary data
90 * Added silc_idlist_get_channels to return all channels from
93 * Implemented LIST command to the server. Affected file is
96 * Implemented the LIST command to the client library and on the
99 * Added [<user count>] argument to the LIST command reply.
100 With private channels the user count is not shown.
102 * Updated TODO and README.
104 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * The client entry's data.registered must be TRUE even with
107 global client entry on global client list. The data.registered
108 is used to check whether the client is anymore in the network,
109 for example with WHOWAS command so it must be valid.
111 * Fixed the WHOWAS command in the server. It now actually works
112 in router environment. Added function into silcd/command_reply.c
113 silc_server_command_reply_whowas_save.
115 * Added silc_idlist_purge function to the silcd/idlist.c
116 to periodically purge the ID Cache.
118 * Fixed INFO command in the server. It works now in router
119 environment. Added <server name> argument to the INFO command
120 reply. Updated the protocol specs.
122 * Fixed minor bug in silc_idcache_purge to not purge if the
123 expire value is zero.
125 * Fixed various bugs in WHOIS and IDENTIFY command handling as
126 they were buggy because of the WHOWAS information.
128 * Fixed local command MSG to handle the async resolving of
129 the remote client properly. It used to fail the first MSG.
130 Affected file silc/local_command.c.
132 * Added `data_len' field to SilcIDCache context.
134 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Update TODO. Todo in commands in the server.
138 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
141 used by routers as broadcast packet to inform other routers
142 about the changed user mode.
144 Implemented the notify handling in the server. Affected file is
145 silcd/packet_receive.c. Added the function
146 silc_server_send_notify_umode to the silcd/packet_send.[ch].
148 * Added new generic Channel Payload and deprecated the New Channel
149 Payload. The New Channel Payload is now the generic Channel
152 * Added new argument `mode' to the silc_server_send_new_channel
153 as it is required in the Channel Payload now.
155 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
156 and created a new and real SilChannelPayload to represent the
157 new generic Channel Payload. Implemented the encode/decode
158 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
160 * Added silc_server_get_client_channel_list to return the list
161 of channels the client has joined for WHOIS command reply.
162 Affected file silcd/server.[ch].
164 * Implemented the channel list sending in the WHOIS command reply
165 in server and in the client.
167 Implemented the channel list displaying on the user interface
168 as well. Affected file silc/client_ops.c.
170 * Added silc_channel_payload_parse_list to parse list of Channel
171 Payloads. It returns SilcDList list of SilcChannelPayloads.
172 Client for example can use this function to parse the list of
173 channels it receives in the WHOIS command reply. The caller
174 must free the list by calling silc_channel_payload_list_free.
175 Affected files lib/silccore/silcchannel.[ch].
177 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Added one new argument <user mode> to the WHOIS command reply
180 to return the mode of the user in SILC. Updated the protocol
183 Implemented it to the server and client.
185 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed the mode printing on the user interface on joining.
188 Affected file silc/client_ops.c.
190 * Implemented the UMODE command and user modes in general to the
191 client library and to the user interface.
193 * Implemented the UMODE command to the server.
195 * The server now sends UNKNOWN_COMMAND error status if client sends
196 unknown command. Affected file silcd/command.c.
198 * All server commands now handle the command identifier the right
199 way when sending the command reply to the client. The client can
200 use to identify the command replies with the identifier.
202 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
204 * Added silc_server_get_client_route to resolve the route to
205 the client indicated by the client ID. Affected file is
208 * Added silc_server_relay_packet as general function to relay
209 packet to arbitrary destination. This deprecates functions
210 like _send_private_message_key, _relay_notify etc. Affected
211 file is silcd/packet_send.[ch].
213 Removed silc_server_send_key_agreement,
214 silc_server_send_private_message_key and
215 silc_server_packet_relay_notify functions from the file
216 silcd/packet_send.[ch].
220 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
221 server. Affected file silcd/packet_receive.[ch].
223 * Implemented the KILL command to the client. Implemented the
224 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
225 Affected files lib/silcclient/command[_reply].c and
226 lib/silcclient/client_notify.c. Implemented the KILL notify
227 printing in the user inteface.
229 * Fixed a lot silc_parse_nick memory leaks from the client
230 library in the file lib/silcclient/command.c.
232 * Changed the silc_server_send_notify_on_channels's `sender'
233 argument from SilcSocketConnection to SilcClientEntry to
234 check the sender as entry and not as connection object and not
235 to send to the client provided as argument. The affected file
236 is silcd/packet_send.[ch].
238 * The notify packets that are destined directly to the client used
239 to not to be processed by the server. Now changed that and the
240 server processes all notify packets. After relaying the packet
241 to the client the notify packet is processed in the server.
243 * The silc_server_free_client_data now checks whether there is
244 pending outgoing traffic for the client and purges the data to
245 the network before removing the client entry.
247 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
250 an client is killed from the SILC Network. Updated the protocol
253 Added new function silc_server_send_notify_killed to the
254 silcd/packet_send.[ch].
256 * Added function silc_server_packet_relay_notify to relay notify
257 packets that are destined directly to a client. In this case
258 the server does not process the notify packets but merely relays
259 it to the client. Affected file silcd/packet_send.[ch].
261 Added also silc_server_packet_process_relay_notify to check
262 whereto relay the notify. Affected file is
263 silcd/packet_receive.[ch].
265 * Implemented the KILL command to the server.
269 * Added the backup schema desgined last fall to the protocol
270 specs for everyone to see. The specification is in the
271 *-spec-xx.txt draft and the packet type definitions for the
272 backup routers is in *-pp-xx.txt draft. Thusly, added also
273 new packet type SILC_PACKET_CELL_ROUTERS.
275 * A big security problem in the implementation discovered. The
276 signoff of an client did not cause new channel key generation
277 which it of course should've done. The channel keys must be
278 always re-generated when client leaves (or signoffs) the channel.
279 The silc_server_remove_from_channels funtion now handles
280 the channel key re-generation.
282 * Added `sender' argument to the silc_server_send_notify_on_channels
283 to not to send the client provided as argument. Affected file
284 silcd/packet_send.[ch].
286 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Implemented OPER and SILCOPER commands into the server and
291 * Added silc_auth_verify and silc_auth_verify_data to verify
292 the authentication directly from the authentication payload.
293 It supports verifying both passphrase and public key based
294 authentication. Affected file lib/silccore/silcauth.[ch].
296 * Added `hash' field to the SilcIDListData structure. It is the
297 hash negotiated in the SKE protocol. Affected file is
300 * Slight redesigning of the SilcAuthPayload handling routines.
301 Do not send SilcPKCS but SilcPublicKey as argument.
303 * Implemented the public key authentication support to the
304 serverconfig. The public key is loaded fromthe provided path
305 and saved as authentication data to void * pointer. Thus,
306 changed the unsigned char *auth_data to void *auth_data;
308 * Fixed SHUTDOWN command to send the reply before the server
309 is shutdown. :) Affected file silcd/command.c.
311 * Fixed fatal bug in CONNECT command. The hostname was invalid
312 memory and server crashed. Affected file silcd/command.c.
314 * Fixed fatal bug in CLOSE command. The server_entry became
315 invalid but was referenced later in the command. Affected file
318 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Fixed fatal bug in failure packet handling. Server ignored
321 the failure and thus crashed when it came.
325 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
328 that the command may be executed only once in (about) 2 seconds.
329 The old SILC_CF_LAG flag is same but allows command bursts up
330 to five before limiting.
332 Added the support for CF_LAG and CF_LAG_STRICT flags to the
333 server code. Various commands now includes the CF_LAG_STRICT
334 flag to disallow any kind of miss-use of the command.
336 * Fixed the silc_buffer_unformat to not to allocate any data
337 if the length of the data is zero. It used to allocate the
338 length + 1. Affected file lib/silcutil/silcbuffmt.c.
340 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Changed the format of AdminConnection configuration section
343 in the server. Added username of the admin to the format.
344 Affected files silcd/serverconfig.[ch].
346 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
347 to return admin configuration data by host, username and/or
350 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Implemented WHOWAS command to the server. Added the functions:
354 silc_server_command_whowas_parse,
355 silc_server_command_whowas_send_reply,
356 silc_server_command_whowas_from_client and
357 silc_server_command_whowas_from_server
359 * Added <Client ID> argument to the WHOWAS command reply. Updated
360 the protocol specs accordingly.
362 * Implemented WHOWAS command and command_reply to the client
365 Implemented the WHOWAS printing on the user interface.
367 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Added new argument to the WHOWAS command reply, the real name.
370 It is an optional argument. Updated the protocol specs.
372 * Added SilcIDCacheDestructor callback that is registered when
373 the SilcIDCache is allocated. The callback is called when
374 an cache entry in the ID Cache expires, or is purged from the
375 cache. Added into lib/silccore/idcache.[ch].
377 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
378 to destruct the client entries when the cache entry expires.
379 Other ID Cache's in server and in the client library ignores
382 * If the ID Cache entry's `expire' field is zero then the entry
383 never expires. Added boolean `expire' argument to the
384 silc_idcache_add function in the lib/silccore/idcache.[ch].
385 If it is TRUE the default expiry value is used.
387 * Added silc_server_free_client_data_timeout that is registered
388 when client disconnects. By default for 5 minutes we preserve
389 the client entry for history - for WHOWAS command.
391 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * Added support to the server to enforce that commands are not
394 executed more than once in 2 seconds. If server receives
395 commands from client more frequently, timeout is registered
396 to process the commands. Affected file silcd/command.c.
397 Added new function silc_server_command_process_timeout.
399 * Changed NICK_NOTIFY handling in client library to check that
400 if the client's nickname was changed, so there is no need to
401 resolve anything from the server.
403 * Removed error printing from the WHOIS and IDENTIFY commands.
404 If error occurs then it is ignored silently in the client library.
405 The application, however, may map the received error to
406 human readable error string. The application currently maps
407 the NO_SUCH_NICKNAME error to string.
409 * Made the command status message public to the application. Moved
410 them from lib/silcclient/command_reply.c to
411 lib/silcclient/command_reply.h. The application can map the
412 received command status to the string with the
413 silc_client_command_status_message function.
415 * Added check to the server to check that client's ID is same
416 as the Source ID in the packet the client sent. They must
419 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
421 * Added dist-bzip hook to the Makefile.am to make bzip2
422 compressed distributions.
424 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Server now enforces the maximum length for the nickname and
427 the channel as protocol specification dictates. 128 bytes for
428 nickname and 256 bytes for channel name.
430 * Moved the WHOIS printing to the application. The client libary
431 does not print out the WHOIS information anymore, the application
432 must do it. Renamed silc_client_command_reply_whois_print to
433 the silc_client_command_reply_whois_save.
435 The client's idle time is also sent to the application now, and
436 the idle is shown on screen.
438 * Added silc_client_command_reply_identify_save to save the
439 received IDENTIFY entries.
441 * Do not check for channel private keys in message sending and
442 reception if the channel does not have the PRIVKEY mode set.
443 Affected file lib/silclient/client_channel.c.
445 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
448 just surfaced after chaning the JOIN procedure.
450 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Added silc_client_get_clients_by_list to get client entries
453 from Client ID list, that is returned for example by JOIN
454 and USERS command replies. The application should use this
455 function for example when JOIN command reply is received to
456 resolve the clients already on the channel (library does not
457 do that anymore as USERS command reply is not used in the JOIN
458 procedure anymore). Affected files lib/silcclient/silcapi.h and
459 lib/silcclient/idlist.c.
461 * JOIN command reply and USERS command reply returns now SilcBuffer
462 pointers instead of unsigned char pointers when returning
463 the client list and mode list.
465 * Added <Client ID> argument to the JOIN command reply, mainly
466 for the server to identify for which client the command was
467 originally sent. Updated protocol specs accordingly.
469 * Added SilcDlist private_key pointer to the SilcChannelEntry
470 in the client to support the channel private keys. Affected
471 file is lib/silcclient/idlist.h.
473 * Added SilcChannelPrivateKey argument to the function
474 silc_client_send_channel_message so that application can choose
475 to use specific private ke if it wants to. If it is not provided,
476 the normal channel key is used, unless private keys are set.
477 In this case the first (key that was added first) is used
478 as the encryption key.
480 * Implemented the support for channel private key handling.
481 Implemented the following functions:
483 silc_client_add_channel_private_key,
484 silc_client_del_channel_private_keys,
485 silc_client_del_channel_private_key,
486 silc_client_list_channel_private_keys and
487 silc_client_free_channel_private_keys
489 Affected file lib/silcclient/client_channel.c.
491 * Added the support for the private keys in the channel message
492 sending and encryption and in the message reception and
493 decryption. Affected funtions are
494 silc_client_send_channel_message and silc_client_channel_message.
496 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Added SKE's key verify callback to the client library's
499 KE protocol context. Affected files lib/silcclient/protocol.[ch].
501 * Removed the statement that server (or router) must send USERS
502 command reply when joining to the channel so that the client
503 knows who are on the channel. Instead, the client list and
504 client's mode list is now sent in the JOIN command reply to the
505 client who joined channel. This is better solution.
507 * Added function silc_server_get_users_on_channel and function
508 silc_server_save_users_on_channel to the silcd/server.[ch].
510 * Removed function silc_server_command_send_users from the
513 * Do not show topic on the client library anymore. The topic is
514 sent in the command reply notify to the application and the
515 application must show the topic now.
517 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Added client searching by nickname hash into the IDENTIFY and
520 WHOIS commands in the server as they were clearly missing from
521 them. Affected file is silcd/command.c.
523 * Fixed a bug in private message receiving in the client library.
524 The remote ID was freed and it wasn't supposed, now it is
527 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Minor fix to the channel payload; allocate the data area, as it
530 needs to be of specific length.
532 * If the key agreement port is zero then the operating
533 system will define the bound port. Affected files are
534 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
536 * Added new function silc_channel_payload_decrypt into the file
537 lib/silccore/silcchannel.[ch].
539 * Moved the channel message etc, check from silc_packet_decrypt
540 to applications. The library calls now a generic
541 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
542 when the packet is either normal or special. This was done to
543 allow more wide range of checking that was not allowed when
544 the code was in library. Now applications can do virtually any
545 checks to the packet and return to the library the decision how
546 the packet should be processed. Affected files are
547 lib/silccore/silcpacket.[ch].
549 Added silc_server_packet_decrypt_check to the server and
550 silc_client_packet_decrypt_check to the client library.
552 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
553 to send with specified source and destination information.
555 * Channel message delivery between routers was broken after the
556 channel key distribution was fixed earlier. The channel key
557 was used be to distributed to other routers as well which is not
558 allowed by the protocol. Now this is fixed and channel keys
559 really are cell specific and the channel message delivery between
560 routers comply with the protocol specification.
562 * Fixed various commands in server to check also the global list
563 for the channel entry and not just the local list. The affected
564 file silcd/command.c.
566 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Added assert()s to buffer formatting and unformatting routines
569 to assert (if --enable-debug) when error occurs. Affected
570 file: lib/silcutil/silcbuffmt.c.
572 * Changed to auto-reconnect to check whether the remote host is
573 router and register the re-connect timeout if it is. It used
574 to check that whether we are normal server, but router must do
575 auto-reconnect with another router as well. Affected file
578 * Removed the [<key len>] option from CMODE command as the cipher
579 name decides the key length, nowadays. See the defined ciphers
580 from the protocol specification.
582 * Added [<hmac>] option to the CMODE command to define the HMAC
583 for the channel. Added SILC_CMODE_HMAC channel mode.
585 * Added [<hmac>] option for the JOIN command so that user can
586 select which HMAC is used to compute the MACs of the channel
589 * Added Hmac field to the Channel Message Payload. The integrity
590 of plaintext channel messages are now protected by computing
591 MAC of the message and attaching the MAC to the payload. The
592 MAC is encrypted. Now, it is clear that this causes some
593 overhead to the size of the packet but rationale for this is that
594 now the receiver can verify whether the channel message decrypted
595 correctly and also when private keys are set for the channel the
596 receiver can decrypt the packet with several keys and check from
597 the MAC which key decrypted the message correctly.
599 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
600 lib/silccrypt/silccipher.[ch].
602 * Added silc_hash_len to return the digest length into the
603 lib/silcrypt/silchash.[ch].
605 * Rewrote parts of Silc Channel Payload interface in the
606 lib/silccore/silcchannel.[ch]. The encode function now also
607 encrypts the packet and parse function decrypts it.
609 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Fixed a minor formatting bug in the SKE's key material processing.
612 It actually might have processed the keys wrong way resulting
615 * Redefined the mandatory HMAC algorithms and added new algorithms.
616 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
617 and hmac-md5 truncated to 96 bits. The mandatory is now
618 hmac-sha1-96. Rest are optional (including the one that used
619 to be mandatory). Rationale for this is that the truncated HMAC
620 length is sufficient from security point of view and can actually
621 make the attack against the HMAC harder. Also, the truncated
622 HMAC causes less overhead to the packets. See the RFC2104 for
625 * Added new [hmac] configuration section. The SKE used to use
626 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
627 is of course wrong. The official names that must be proposed in
628 the SKE are the ones defined in the protocol specification
629 (hmac-sha1-96 for example). The user can configure any hmac
630 using any hash function configured in the [hash] section. At
631 least, the mandatory must be configured.
633 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
635 * Added HMAC list to the SKE proposal list. It has now both
636 hash algorithm list and HMAC list. This makes the protocol
637 incompatible with previous versions. The SKE now seems to work
638 the way it is supposed to work, for the first time actually.
640 * Defined plain Hash algorithms to the protocol specification.
643 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Implemented support for key agreement packets into the server.
646 Added functions silc_server_key_agreement and
647 silc_server_send_key_agreement. Other than these functions,
648 server has nothing to do with this packet.
650 * Added support for private message key packets into the server.
651 Added functions silc_server_private_message_key and
652 silc_server_send_private_message_key.
656 * Changed the silc_[client|server]_protocol_ke_set_keys to be
657 called in the protocol's final callback instead in the END
658 protocol state. This makes a little more sense and in the same
659 time in client we can use the same protocol routines for normal
660 key exchange and to key agreement packet handling as well.
662 * Added to both client's and server's KE protocol context the
663 SilcSKEKeyMaterial pointer to save the key material. We will
664 bring the key material to the protocol's final callback by doing
665 this. The final callback must free the key material.
667 * Added SKE's packet_send callback into client's KE protocol
668 context so that the caller can choose what packet sending function
669 is used. This way we can use different packet sending when
670 doing normal SKE when doing key agreement packet handling (in
671 the key agreement packet handling we do not want to encrypt
674 * Implemented the responder side of the key agreement routines
675 in the client. The client can now bind to specified port and
676 accept incoming key negotiation. The key material is passed
677 to the application after the protocol is over.
679 * Implemented the processing of incoming Key Agreement packet
680 in the client. Added function silc_client_key_agreement to
683 * Implemented the intiator side of the key agreement routines
684 in the client. The client can now initiate key agreement with
685 another remote client. The key material is passed to the
686 application after the protocol is over.
688 * Created client_keyagr.c to include all the key agreement
691 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
692 SILC_TASK_CALLBACK except that it is not static.
694 * Created client_notify.c and moved the Notify packet handling
695 from the client.[ch] into that file.
697 * Created client_prvmsg.c and moved all private message and
698 private message key routines from the client.[ch] into that file.
700 * Create client_channel.c and moved all channel message and
701 channel private key routines from the client.[ch] into that file.
703 * Changed silc_client_get_client_by_id_resolve to resolve with
704 WHOIS command instead of IDENTIFY command, in the file
705 lib/silclient/idlist.c.
707 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Implemented the SKE's responder side to the Client library.
711 * When FAILURE is received to the protocol do not trust it
712 blindly. Register a timeout to wait whether the remote closes
713 the connection as it should do it, only after that process the
714 actual failure. This was changed to both client and server.
716 * Added client_internal.h to include some of the structures
717 there instead of client.h in lib/silcclient/.
719 * Added function silc_task_unregister_by_callback to unregister
720 timeouts by the callback function.
722 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Some "Incomplete WHOIS info" errors has been appearing on the
725 log files. Took away the entry->userinfo check from WHOIS
726 reply sending. The entry->userinfo is now " " if client did not
727 provide one. I thought this was fixed earlier but something
728 is wrong still. Let's see if the error still appears.
730 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Fixed a minor bug in the login when the channel key is
733 re-generated in the server. It used to generate the key in
734 wrong order and thus caused problems in the channel traffic.
736 * Fixed a minor bug in channel key distsribution after
737 KICK command. The key was not sent to the router even though
740 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
742 * Added silc_ske_process_key_material_data as generic routine
743 to process any key material as the SILC protocol dictates. The
744 function is used by the actual SKE library but can be used by
745 applications as well. This relates to the private message keys
746 and the channel private keys since they must be processed the
747 same way the normal SILC session keys. The protocol dictates
748 this. Affected files: lib/silcske/silcske.[ch].
750 Added also silc_ske_free_key_material to free the
751 SilcSKEKeyMaterial structure.
753 * Defined silc_cipher_set_key function to set the key for
754 cipher without using the object's method function. The affected
755 files: lib/silccrypt/silccipher.[ch].
757 * Implemented silc silc_client_add_private_message_key,
758 silc_client_add_private_message_key_ske,
759 silc_client_del_private_message_key,
760 silc_client_list_private_message_keys and
761 silc_client_free_private_message_keys functions in the
764 Added functions silc_client_send_private_message_key to send
765 the Private Message Key payload and silc_client_private_message_key
766 to handle incoming Private Message Key payload.
768 * Added Cipher field to the Private Message Key payload to set
769 the cipher to be used. If ignored, the default cipher defined
770 in the SILC protocol (aes-256-cbc) is used.
772 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Removed lib/silcclient/ops.h file.
776 Redefined parts of the SILC Client Library API. Created new
777 file silcapi.h that deprecates the ops.h file and defines the
778 published Client Library API. Defined also private message key
779 API and channel private key API into the file.
781 This is the file that the application must include from the
782 SILC Client Library. Other files need not be included by
783 the application anymore.
785 * Added new key_agreement client operation callback and also
786 defined the Key Agreement library API for the application.
788 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
791 is used by clients to request key negotiation between another
792 client in the SILC network. If the negotiation is started it
793 is performed using the SKE protocol. The result of the
794 negotiation, the secret key material, can be used for example
795 as private message key.
797 Implemented the Key Agreement payload into the files
798 lib/silccore/silauth.[ch].
800 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Redefined ciphers for the SILC protocol. Added some new ciphers
803 and defined the key lengths for the algorithms. Changed the
804 code accordingly. The default key length is now 256 bits.
806 * Fixed SKE key distribution function silc_ske_process_key_material
807 when the key length is more than 128 bits. The default key
808 length in SILC is now 256 bits.
810 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
811 to indicate unsupported algorithm.
813 * Renamed rijndael.c to aes.c and all functions as well.
815 * Fixed a long standing channel key setting bug in client library.
816 Weird that it has never surfaced before.
818 * Fixed bug in channel deletion. If the entire channel is removed
819 then it must also delete the references of the channel entry
820 from the client's channel list as the client's channel entry and
821 the channel's client entry share same memory.
823 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Implemented CONNECT and SHUTDOWN commands in the client.
827 * Implemented CLOSE command to the client.
829 * Added the function silc_idlist_find_server_by_name into the
830 files silcd/idlist.[ch].
832 Added the function silc_idlist_find_server_by_conn into the
833 files silcd/idlist.[ch].
835 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * DIE command was renamed to SHUTDOWN. Updated the both code
840 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
841 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
843 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
846 * Added function silc_server_create_connection function to create
847 connection to remote router. My server implementation actually
848 does not allow router to connect to normal server (it expects
849 that normal server always initiates the connection to the router)
850 so the CONNECT command is only good for connecting to another
853 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
856 or some other client was kicked from the channel.
858 Implemented the handling of the notify type to both client
861 Implemented silc_server_send_notify_kicked to send the KICKED
862 notify. It is used to send it to the server's primary router.
864 * Implemented the KICK command into server and client.
866 * Added `query' argument to the silc_idlist_get_client function
867 to indicate whether to query the client from server or not if
870 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
871 to indicate that the client is not channel founder.
875 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Removed the rng context from SilcPacketContext structure and
878 changed that the packet routine uses the Global RNG API.
880 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Added support for quit message that client can "leave" on the
883 channel when it quits the SILC. It is ditributed inside the
884 SILC_NOTIFY_TYPE_SIGNOFF notify type.
886 Added silc_server_free_client_data that will take the
887 signoff message as argument.
889 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
891 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Updated parts of the protocol specification to keep it up
896 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
899 payloads in one packet.
901 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
902 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
903 use now the new List flag.
905 * Also deprecated the following packet types: REPLACE_ID,
906 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
908 * Added list support for Notify packet in server.
910 * Added silc_server_send_notify_channel_change to send the
911 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
912 the silc_server_send_replace_id.
914 * Added silc_server_send_notify_nick_change to send the
915 NICK_CHANGE notify type. Deprecates the function
916 silc_server_send_replace_id.
918 * Added silc_server_send_notify_join to send the JOIN notify type.
919 Deprecates the function silc_server_send_new_channel_user.
921 * Added silc_server_send_notify_leave to send LEAVE notify type.
922 Deprecates the function silc_server_send_remove_channel_user.
924 * Added silc_server_send_notify_cmode and
925 silc_server_send_notify_cumode to send CMODE and CUMODE notify
926 types. Deprecates the silc_server_send_set_mode function.
928 * Added SERVER_SIGNOFF notify type to indicate that server has
929 quit. This means that all clients on the channel from that
930 server will drop. This can be also used when netsplit happens.
932 Deprecated REMOVE_ID packet type since it is not needed anymore
935 Added silc_server_send_notify_server_signoff to send the
936 SERVER_SIGNOFF notify type. Deprecates the function
937 silc_server_send_remove_id.
939 Added also silc_server_send_notify_signoff to send the
942 * Employed the PKCS #1. It is the mandatory way to do RSA in the
943 SILC protocol from this day on. Changed the protocol
944 specification as well.
946 * Added silc_server_send_notify_topic_set to send TOPIC_SET
947 notify type. It is used between routers to notify about
948 topic changes on a channel.
950 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
953 * Partly updated the protocol specification to comply with the
954 changes now made. It is still though a bit outdated.
956 * The JOIN notify type now takes one extra argument <Channel ID>.
957 The packet used to be destined to the channel but now the
958 JOIN type may be sent as list thus it is impossible to
959 destine it to any specific channel. By adding this argument
960 it is again possible.
962 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Added CREDITS file. The CHANGES and CREDITS file will appear
965 in the distribution as well.
967 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
970 types in the server's silcd/packet_receive.c.
972 * Implemented CMODE and CUMODE to work in router environment.
974 * Fixed minor encoding and decoding buglet from the
975 lib/silccore/silcmode.c.
977 * Fixed buffer overflow from lib/silcclient/command.c in USERS
980 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
982 * Changed all SilcConfigServer* and silc_config_server* to
983 SilcServerConfig* and silc_server_config*, respectively.
986 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Associated the ID (client or server ID) to the Authentication
989 Payload to avoid any possibility of forging. Updated the
990 protocol specification and the code accordingly.
992 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * The RSA key length is now save to the RsaKey context in the
995 key generation process in lib/silccrypt/rsa.c. The key length
996 is now used to figure out the maximum size of the block allowed
997 to be encrypted/signed.
999 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1000 is equivalent to the silc_mp_mp2bin but does not allocate any
1003 * Changed silc_mp_mp2bin API to take length argument. If it is
1004 non-zero then the buffer is allocated that large. If zero, then
1005 the size is approximated using silc_mp_sizeinbase, which however
1008 * Created Global RNG API which is global RNG that application can
1009 initialize. After initializing, any routine anywhere in the
1010 code (including library) can use RNG without allocating a new
1011 RNG object. This was done to allow this sort of use of the
1012 RNG in code that has no chance to allocate RNG object. All
1013 applications currently allocate this and many routines in the
1014 library use this. Affected file lib/silccrypt/silcrng.[ch].
1016 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1017 it to use the Global RNG API.
1019 * Defined Authentication Payload into protocol specification that
1020 is used during SILC session to authenticate entities. It is
1021 used for example by client to authenticate itself to the server
1022 to obtain server operator privileges.
1024 Implemented this payload into the lib/silccore/silcauth.[ch].
1025 Implemented also routines for public key based authentication
1026 as the new protocol specification dictates.
1028 Moved definitions of different authentication methods from
1029 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1031 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1032 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1033 silc_pkcs_verify_with_hash functions into the file
1034 lib/silccrypt/silcpkcs.[ch].
1036 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * The client entry's userinfo pointer must be always valid.
1039 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1040 will fail since it requires the userinfo. Now, the userinfo
1041 is allocated as "" if actual userinfo does not exist. Actually,
1042 it must exist and it is totally Ok to drop client connections
1043 that does not announce the userinfo. However, we will make
1044 this workaround for now.
1046 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1047 to return the remote port by socket.
1049 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1052 SILC_SERVER_PENDING_EXEC and added an new macro
1053 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1054 data or when error occurs while processing the pending command.
1056 Added new argument `destructor' into silc_server_command_pending
1057 and to the SilcServerCommandPending object. This destructor is
1058 now called after calling the pending callback or if error occurs
1059 immediately. If error occurs the actual pending callback won't
1060 be called at all - only the destructor. The destructor may be
1061 NULL if destructor is not needed.
1063 All this applies for client library code as well. Similar
1064 changes were made there as well for the pending commands.
1066 In the client, the application must now allocate the
1067 SilcClientCommandContext with the silc_client_command_alloc
1070 * Added reference counter to the SilcServerCommandContext. Added
1071 function silc_server_command_alloc and silc_server_command_dup
1074 Same type of functions added to the client library for the same
1077 * Removed the cmd_ident from IDListData away since it is now
1078 global for all connections. It is the command identifier used
1079 in command sending and with pending commands. The affected file
1082 * Added reference counter to the SilcSocketConnection objecet to
1083 indicate the usage count of the object. The object won't be
1084 freed untill the reference counter hits zero. Currently only
1085 server uses this, and client ignores it. The client must be
1086 set to use this too later. The affected files are
1087 lib/silccore/silcsockconn.[ch]. Added also the function
1088 silc_socket_dup to increase the reference counter.
1090 This was mainly added because it is possible that the socket
1091 is removed underneath of pending command or other async
1092 operation. Now it won't be free'd and proper DISCONNECTING
1093 flags, etc. can be set to avoid sending data to connection that
1094 is not valid anymore.
1096 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1097 the connection. After that it sets SILC_SET_DISCONNECTED.
1098 It is, however, possible that the socket data is not still freed.
1099 The silc_server_packet_process now checks that data is not
1100 read or written to connection that is DISCONNECTED. The socket
1101 get's freed when the reference counter hits zero.
1103 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Changed the client operation API: channel_message operation's
1106 `sender' is now the client entry of the sender, not the nickname
1107 and the `channel' is the channel entry, not the channel name.
1109 In the private_message operation the `sender' is now also the
1110 client entry of the sender not the nickname.
1112 Affected file is lib/silcclient/ops.h and all applications
1113 using the client operations.
1115 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Moved the calling of ops->connect() from connect_to_server_final
1118 into receive_new_id functin since that is the point when the
1119 client is actually allowed to send traffic to network. The
1120 affected file is lib/silcclient/client.c.
1122 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1125 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1126 (if needs broadcasting) instead of broadcasting the packets one
1127 by one which would make a burst in the network traffic.
1129 * Added `broadcast' argument to the functions in silcd/server.[ch]
1130 silc_server_create_new_channel[_with_id] to indicate whether
1131 to send New Channel packet to primary router.
1133 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added new function into the silcd/server.[ch] files:
1136 silc_server_create_new_channel_with_id to create new channel with
1137 already existing Channel ID.
1139 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1140 lib/silccore/silcpacket.h. This packet is used t send list of
1141 Set Mode payloads inside one packet. Server uses this to set
1142 the modes for the channels and clients on those channels, that it
1143 announced to the router when it connected to it. The protocol
1144 specification has been updated accordingly.
1146 * The silc_server_new_channel did not handle the packet coming
1147 from normal server as it normally does not send that. However,
1148 when it announces its channels it does send it. Implemented
1149 the support for that.
1151 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1152 into the file lib/silccore/id.h.
1154 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Fixed memory leaks in the functions silc_idlist_del_client,
1157 silc_idlist_del_channel and silc_idlist_del_server in the file
1158 silcd/idlist.c. All of those leaked like a sieve.
1160 * Fixed some small memory leaks in the client's function
1161 silc_client_notify_by_server.
1163 * Added functions into silcd/server.c: silc_server_announce_clients,
1164 silc_server_announce_channels and silc_server_announce_server.
1165 These functions are used by normal and router server to announce
1166 to its primary router about clients, channels and servers (when
1167 router) that we own. This is done after we've connected to the
1170 These functions effectively implements the following packet types:
1171 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1172 and SILC_PACKET_NEW_ID_LIST.
1174 * Added new functions into the silcd/packet_receive.[ch]:
1175 silc_server_new_id_list, silc_server_new_channel_list and
1176 silc_server_new_channel_user_list to handle the incoming
1177 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1179 * Added support of changing Channel ID in the function
1180 silc_server_replace_id. If the server that announces a channel
1181 to the router already exists in the router (with same name but
1182 with different Channel ID), router is responsible to send
1183 Replace ID packet to the server and force the server to change
1184 the Channel ID to the one router has.
1186 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1187 client that the Channel ID has been changed by the router. The
1188 normal server sends this to the client. Client must start using
1189 the new Channel ID as the channel's ID.
1191 Implemented handling of this new type into lib/silcclient/client.c
1192 into the function silc_client_notify_by_server.
1194 * Added new function silc_idlist_replace_channel_id into the files
1195 silcd/idlist.[ch] to replace the Channel ID.
1197 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Call silc_server_command_identify_check always when processing
1200 the IDENTIFY command in silcd/command.c
1202 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1205 send keepalive packets. The packet can be sent by clients,
1206 servers and routers.
1208 Added function silc_socket_set_heartbeat into the file
1209 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1210 If not set, the heartbeat is not performed. The actual
1211 heartbeat is implemented in the low level socket connection
1212 library. However, application is responsible of actually
1215 Added silc_server_send_heartbeat to send the actual heartbeat
1216 packet into silcd/packet_send.[ch]. Server now performs
1217 keepalive with all connections.
1219 * Added silc_task_get_first function into lib/silcutil/silctask.c
1220 to return the timeout task with shortest timeout. There was a bug
1221 in task unregistration that caused problems. TODO has been
1222 updated to include that task system must be rewritten.
1224 * The client library will now resolve the client information when
1225 receiving JOIN notify from server for client that we know but
1226 have incomplete information.
1228 * Rewrote parts of silc_server_remove_from_channels and
1229 silc_server_remove_from_one_channel as they did not remove the
1230 channel in some circumstances even though they should've.
1232 * Encryption problem encountered in server:
1234 The LEAVE command used to send the Channel Key packet to the
1235 router immediately after generating it. However, the code
1236 had earlier sent Remove Channel user packet but not immediately,
1237 ie. it was put to queue. The order of packets in the router
1238 was that Channel Key packet was first and Remove Channel User
1239 packet was second, even though they were encrypted in the
1240 reverse order. For this reason, MAC check failed. Now, this
1241 is fixed by not sending the Channel Key packet immediately but
1242 putting it to queue. However, this is more fundamental problem:
1243 packets that are in queue should actually not be encrypted
1244 because packets that are sent immediately gets encrypted
1245 actually with wrong IV (and thus MAC check fails). So, packets
1246 that are in queue should be encrypted when they are sent to
1247 the wire and not when they put to the queue.
1249 However, the problem is that the current system has not been
1250 designed to work that way. Instead, the packet is encrypted
1251 as soon as possible and left to the queue. The queue is then
1252 just purged into wire. There won't be any fixes for this
1253 any time soon. So, the current semantic for packet sending
1256 o If you send packet to remote host and do not force the send
1257 (the packet will be in queue) then all subsequent packets to the
1258 same remote host must also be put to the queue. Only after the
1259 queue has been purged is it safe again to force the packet
1262 o If you send all packets immediately then it safe to send
1263 any of subsequent packets through the queue, however, after
1264 the first packet is put to queue then any subsequent packets
1265 must also be put to the queue.
1267 Follow these rules and everything works fine.
1269 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added new function silc_server_remove_clients_by_server to
1272 remove all client entries from ID list when the server connection
1273 is lost. In this case it is also important to invalidate all
1274 client entires as they hold the invalid server entry. This
1275 fixes fatal bug when server has lost connection and will reconnect
1278 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Made some sanity checks to silc_server_daemonise like to check
1281 whether the requested user and group actually exists.
1283 * Added sanity check to SKE's silc_ske_responder_finish to check
1284 that the public and private key actually is valid.
1286 * Invalidate the client's nickname when receiving Replace ID
1287 packet and the Client ID is being replaced. This means that the
1288 server will query the nickname if someone needs it (client)
1291 * Sort the ID Cache in client library when the ID Cache data
1292 has changed (needs sorting).
1294 * Do not allow for SILC client to create several connections to
1295 several servers. The client does not support windows right now
1296 and generating multiple connections causes weird behaviour.
1298 Irssi-silc client does support windows and can handle several
1299 connections without problems, see: www.irssi.org and SILC plugin.
1301 * Fixed some places where client was added to the IDList. The
1302 rule of thumb is following (in order to get everything right):
1303 If the client is directly connected local client then the
1304 `connection' argument must be set and `router' argument must be
1305 NULL to silc_idlist_add_client function. If the client is not
1306 directly connected client then the `router' argument must
1307 bet set and the `connection' argument must be NULL to the
1308 silc_idlist_add_client function.
1310 * The funtion silc_server_packet_send_local_channel actually did
1311 not check whether the client was locally connected or not. It
1312 does that now. Fixed a bug related to LEAVE command.
1314 * Fixed Remove Channel User payload parsing bug in server's
1315 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1317 * The server's silc_server_save_channel_key now checks also the
1318 global ID list for the channel as it might not be in the local
1319 list. Fixed a bug related to LEAVE command.
1321 * Is this the end of the [<unknown>] buglet that has been lurking
1322 around for a long time? A little for loop fix in server's
1323 silc_server_command_whois_parse that is used by both IDENTIFY
1324 and WHOIS command. At least, this was a clear bug and a cause
1325 of one type of [<unknown>] buglet.
1327 * WHOIS and IDENTIFY commands call the function
1328 silc_server_command_[whois/identify]_check function even if
1329 we are not router server.
1331 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1333 * Added --with-gmp configuration option. If set the GMP
1334 is always compiled in the SILC source tree. If not set then
1335 it is checked whether the system has the GMP3 installed. If
1336 it has then the GMP won't be compiled (the system's headers
1337 and library is used), if it doesn't have it then the GMP is
1338 compiled in the SILC source tree.
1340 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Changed RSA private exponent generation to what PKCS #1
1343 suggests. We try to find the smallest possible d by doing
1344 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1345 not security fix but optimization.
1347 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Added new config entry [Identity] to fork the server and run
1350 it as specific user and group. A patch from Bostik.
1352 * Imported Dotconf configuration library into lib/dotconf.
1353 This will be used to create the SILC configuration files later.
1354 It will appear in the distsribution after this commit.
1356 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * A big code auditing weekend happening. Auditing code for
1359 obvious mistakes, bugs and errors. Also, removing any code
1362 Removed files for being obsolete:
1364 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1365 inline in the file lib/silcutil/silcbuffer.h)
1367 o lib/silcutil/silcbufutil.c (the header has inline versions)
1369 Changed code to fix possible error conditions:
1371 o The buffer formatting routines now check that the destination
1372 buffer really has enough space to add the data. This applies for
1373 both buffer formatting and unformatting
1374 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1375 unformatting was changed to accomodate following rules:
1376 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1377 sent to the function while XXX_*STRING will not allocate or copy
1378 the data into the buffer. Instead it sets the pointer from the
1379 buffer into the pointer sent as argument (XXX_*STRING used to
1380 require that the pointer must be allocated already). This change
1381 makes this whole thing a bit more consistent and more optimized
1382 (note that the data returned in the unformatting with XXX_*STRING
1383 must not be freed now). The routines return now -1 on error.
1385 o Tried to find all code that use buffer_format and buffer_unformat
1386 and added return value checking to prevent formatting and
1387 especially unformatting errors and possible subsequent fatal
1390 o Changed ske->x and ske->KEY to mallocated pointers in
1391 lib/silcske/silcske.h. Fixed possible data and memory leak.
1393 o Added return value checking to all *_parse* functions. Fixed
1394 many memory leaks as well.
1396 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1397 so that buffer overflows would not happen. All code now also
1398 checks the return value as it can fail.
1400 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Added reconnection support to server if the normal server looses
1403 its connection to the router (for example if router is rebooted).
1404 The server performs normal reconnection strategy implemented
1405 to the server. Affected file silcd/server.c.
1407 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Added new packet type SILC_PACKET_SET_MODE that is used to
1410 distribute the information about changed modes (for clients,
1411 channels and clients channel modes) to all routers in the
1412 network. Updated the protocol specification accordingly.
1414 Added functions into silcd/packet_send.c and
1415 silcd/packet_receive.c: silc_server_send_set_mode,
1416 silc_server_set_mode.
1418 Added new files silcmode.[ch] into lib/silccore that implements
1419 the encoding and decoding of Set Mode Payload. Added new type
1420 SilcSetModePayload. Moved the definitions of different modes
1421 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1423 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Oops, a little mistake in server's connection authentication
1426 protocol. The protocol is not ended with FAILURE but with
1427 SUCCESS if the authentication is Ok. :) Affected file is
1430 * Implemented NICK_CHANGE notify handling in server in the file
1431 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1432 the local clients on the channel. After the changing nickname
1433 in router environment snhould work and the [<unknown>] nickname
1434 should appear no more.
1436 The silc_server_replace_id function that receives the Replace ID
1437 payload now sends the NICK_CHANGE notify type also in the file
1438 silcd/packet_receive.c
1440 * Changed WHOIS and IDENTIFY command to support the maximum amount
1441 of arguments defined in protocol specs (3328 arguments). This
1442 fixed a bug that caused problems when there were more than three
1445 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Added extra parameter, command identifier, to the
1448 silc_client_send_command so that explicit command identifier
1451 Changed that ID list routines uses specific command identifier
1452 when sending WHOIS/IDENTIFY requests to the server so that they
1453 can be identified when the reply comes back.
1455 Affected files lib/silcclient/command.[ch],
1456 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1458 * Added `sender' argument to silc_server_packet_send_to_channel
1459 to indicaet the sender who originally sent the packet to us
1460 that we are now re-sending. Ignored if NULL. Affected file
1461 silcd/packet_send.[ch].
1463 * Added some server statistics support in silcd/server_internal.h
1464 SilcServerStatistics structure and around the server code. Also
1465 send some nice statistics information when client is connecting
1468 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Fixed channel ID decoding in server's JOIN command reply in
1471 silcd/command_reply.c
1473 * Fixed braodcasting of replace ID payload to not to send it if
1474 we are standalone server in silcd/packet_receive.c.
1476 * Fixed all channel message sending routines to not to send
1477 packets to clients that has router set, since they are routed
1478 separately in the same function earlier. Affects file
1479 silcd/packet_send.c and all channel packet sending functions.
1481 * In USERS reply, res_argv[i] are not allocated, the table
1482 is allocated. Thus changed that free the table, not its
1485 * In server's whois_check and identify_check if the client is
1486 locally connected do not send any WHOIS commands - they are not
1489 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Fixed some minor bugs in client when sending WHOIS command. The
1492 arguments was in wrong order.
1494 * Removed statis function add_to_channel from server in
1495 silcd/command.c that was previously used with the joining but
1498 * Tested USERS command in router environment successfully with two
1499 routers, two servers and two clients.
1501 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Reorganized the USERS command and command reply in client library
1504 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1505 When the command is given by user we register a pending command
1506 callback that will reprocess the command after the reply has been
1507 received from the server. When reprocessing the packet we then
1508 display the information. Thus, the USERS information is displayed
1509 now in the command callback instead of in the command reply
1510 callback. The processing of the command is same as previously
1511 when server has sent the command reply in the JOINing process.
1513 * Added to USERS command in silcd/command_reply.c to join the client,
1514 we didn't use to know about, to the channel after we've created
1515 a client entry for it. Also, for clienet we did know already still
1516 check whether it is on the channel or not and add it if not.
1518 * Removed silc_server_command_join_notify as the function and its
1521 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Changed the client's pending command handling to the same as the
1524 server's pending command handling. It is also now possible to
1525 execute command reply functions from other command reply
1526 function as the function callbacks for commands and command
1527 replies are one and same. The pending commands are not static
1528 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1529 in client connection context. Thus, pending commands are server
1530 connection specific as it is convenient.
1532 Changed the function silc_client_command_pending and
1533 silc_client_command_pending_del and added new function
1534 silc_client_command_pending_check. Removed the
1535 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1538 * Added cmd_ident, current command identifier, to the client
1539 connection context in lib/silcclient/client.h to keep track on
1540 command identifiers used in command sending. Client's command reply
1541 function handling now supports the mandatory command identifiers.
1543 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1544 funtions in client to fully support pending command callbacks.
1546 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1547 as one of the arguments to the application in the command reply
1550 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1551 before first releasing SILC but came back. Now it is removed again
1552 and should come back nomore. The FORWARDED flag was used only
1553 by the JOINing procedure by forwarding the command packet to router.
1554 Now, the JOINing procedure has been changed to more generic (due
1555 to various router environment issues) and FORWARDED is not needed
1556 anymore for anything. The protocol specification is yet to be
1559 Now, removed silc_server_packet_forward from server and the flag
1560 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1562 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Renamed NAMES command to USERS command. The NAMES was named that
1565 due to historical reasons. Now it is renamed. Also, rewrote
1566 parts of the USERS command. The nickname list is not sent anymore
1567 by the server. Only Client ID and mode lists are sent in the USERS
1568 command. Changed this also to the protocol specification.
1570 The client now resolves the names and stuff after it receives
1571 the USERS list from the server when joining to the channel.
1573 * WHOIS and IDENTIFY commands has been changed to support multiple
1574 Client ID's per command. One can now search for multiple users
1575 in the network by sending only one WHOIS or IDENTIFY command.
1576 Changed the code and the protocol specifications.
1578 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1579 uses silc_server_command_whois_parse to parse the request. */
1581 * If normal server, do not parse the WHOIS and IDENTIFY requests
1582 before sending it to the router. Saves some time.
1584 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Fixed JOIN command on client library. Wrong number of arguments
1587 used to crash the client.
1589 * Added silc_server_channel_has_global function to check whether
1590 channel has global users or not.
1592 * Added silc_server_channel_has_local function to check whether channel
1593 has locally connected clients on the channel.
1595 * The silc_server_remove_from_one_channel now checks whether the
1596 channel has global users or not after given client was removed from
1597 the channel. It also checks whether the channel has local clients
1598 on the channel anymore. If it does not have then the channel entry
1599 is removed as it is not needed anymore.
1601 * The silc_server_notify now checks on JOIN notify whether the joining
1602 client is one of locally connected or global. If it is global then
1603 the channel has now global users on the channel and that is marked
1604 to the channel entry. Also, it now saves the global client to
1605 global list who is joining and JOINs it to the channel. This is
1606 for normal server, that is.
1608 Changed silc_server_send_notify_on_channel,
1609 silc_server_packet_relay_to_channel and
1610 silc_server_packet_send_to_channel check if we are normal server
1611 and client has router set (ie. global client) do not send the
1612 message to that client, as it is already routed to our router.
1614 * Implemented LEAVE notify type handling in silc_server_notify
1617 * Tested LEAVE command in router environment successfully. Tested
1618 with two routers, two servers and two clients.
1622 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1624 * Implemented SIGNOFF notify type handling in silc_server_notify
1627 * silc_server_remove_id now removes the client entry from all channels
1628 it has joined and thusly sends SIGNOFF notify type.
1630 * Rewrote the NAMES list generation in server by removing two excess
1631 loops. The lists are created now inside one loop.
1633 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * silc_server_remove_channel_user checks now also global list
1636 for channel and client.
1638 * silc_server_new_channel_user checks now both local and global
1639 list for channel and client. Fixed a bug in client id decoding.
1640 Used to decode wrong buffer.
1642 * silc_server_channel_message checks now both local and global
1643 list for channel entry.
1645 * Tested channel joining (hence JOIN) in router environment
1646 successfully. Tested with two routers, two servers and two
1649 * Tested channel message sending in router environment successfully.
1651 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Added silc_server_save_channel_key into server.[ch] to save the
1654 received channel key in Channel Key payload processing. It is
1655 also used in JOIN command reply handling.
1657 Equivalent function silc_client_save_channel_key added into
1658 client.[ch] into client library.
1660 * Changed JOIN command reply to send information whether the channel
1661 was created or not (is existing already) and the channel key
1662 payload. Changed protocol specs accordingly.
1664 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1665 the request was sent by ID and not by nickname. Crashed on
1668 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1671 now correctly save the received data.
1673 * silc_server_free_sock_user_data now notifies routers in the
1674 network about entities leaving the network.
1676 At the same time implemented functions silc_server_remove_id
1677 and silc_server_send_remove_id to receive and send REMOVE_ID
1678 packets. The packet is used to notify routers in the network
1679 about leaving entities. The ID removed will become invalid in
1682 * Added function silc_idlist_del_server into server. Removes and
1683 free's server entry from ID list.
1685 * silc_server_private_message function now checks, if we are router,
1686 that the destination ID really is valid ID, naturally.
1688 * In router when NEW_ID packet is received (for new client) the
1689 hash of the Client ID is saved in the ID Cache but the
1690 client->nickname is set to NULL, instead of putting the hash
1693 IDENTIFY command now also checks that client->nickname must be
1694 valid. If it is not if will request the data from the server who
1695 owns the client. Added new function
1696 silc_server_command_identify_check.
1698 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1699 to set the command to already allocated Command Payload.
1701 * Tested private message sending in router environment with two
1702 routers, two servers and two clients. Fixed minor bugs and now
1705 * Fixed segfault from client's NAMES command. Used to crash if
1708 * Forwarded packets must not be routed even if it is not destined
1709 to the receiver. Changed server code comply with this.
1711 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Added `require_reverse_mapping' boolean value to ServerParams
1714 structure. If TRUE (not default) the server will require that
1715 the connecting host has fully qualified domain name.
1717 If the reverse mapping is not required and hostname could not be
1718 found the IP address is used as hostname.
1720 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Implemented version string checking to both client and server.
1723 The check is incomplete currently due to the abnormal version
1724 strings used in development version of SILC.
1726 * Changed all command functions in server to use the new
1729 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Changed char *data to unsigned char *data in ID Cache system to
1732 support binary data as ID Cache data. Changed code to support
1733 binary data in lib/silccore/idcache.c.
1735 * Renamed silc_server_packet_relay_command_reply to
1736 silc_server_command_reply as it is normal packet receiving
1737 function. Rewrote the function to accept command replys for
1738 servers and not only for clients.
1740 * Mark remote router always as registered server if we are connecting
1741 to it. Otherwise, commands sent by the router to us are ignored.
1743 * All ID List find routines now returns the ID Cache Entry pointer
1744 as well if requested.
1746 * WHOIS command works now in router environment, tested with two
1747 routers, two servers and two clients.
1749 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1750 in router environment (as it is almost equivalent to WHOIS) but
1751 hasn't been tested thoroughly. Added new functions:
1753 silc_server_command_identify_parse
1754 silc_server_command_identify_send_reply
1755 silc_server_command_identify_from_client
1756 silc_server_command_identify_from_server
1758 * Disabled route cache adding because adding two different ID's with
1759 same IP replaces the old cache entry thus giving wrong route.
1760 The entry->router->connection is always the fastest route anyway
1761 so route cache may not be needed. Of course, new routes maybe
1762 established after receiving the ID when the entry->router->connection
1763 might not be anymore the most optimal.
1765 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Add route cache for received ID for fast routing.
1769 * Added silc_server_packet_route to route received packet on router
1770 that is not destined to us.
1772 * Renamed silc_server_get_route to silc_server_route_get.
1774 * Added id_string and id_string_len fields into SilcServer to
1775 include encoded ServerID for fast comparing without excess
1776 encoding of the ID's.
1778 * Cleaned up WHOIS command on server side. Added following static
1781 silc_server_command_whois_parse
1782 silc_server_command_whois_check
1783 silc_server_command_whois_send_reply
1784 silc_server_command_whois_from_client
1785 silc_server_command_whois_from_server
1787 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1788 arguments in command replies. All command functions should be
1789 updated to use this macro.
1791 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Minor typo fixes on command reply handling on server.
1795 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Added silc_server_command_add_to_channel internal routine to add
1798 the client to the channel after router has created the channel and
1799 sent command reply to the server.
1801 * Added generic silc_server_send_command to send any command from
1804 * Use static buffer with ID rendering instead of duplicating data.
1806 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Fixed a channel user mode bug when joining to a channel server gave
1809 everybody channel founder rights, oops.
1811 * We mark ourselves as the router of the incoming server connection
1812 if we are router ourselves. This way we can check in some packet
1813 sending functions whether it is locally connected server. For
1814 incoming router connections we put NULL.
1816 * For router sending packets locally means now always sending the
1817 packet cell wide; to local clients and local servers. For normal
1818 server sending packet locally means sending it to only local
1821 * Fixed the JOIN command to really work in router environment. If the
1822 channel is created it is always created by the router. Router is
1823 also responsible of making the initial joining to the channel,
1824 sending JOIN notify to the sending server and distributing
1825 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1826 does not exist server doesn't do anything else but forward the
1827 command to the router which performs everything.
1829 * Added silc_server_send_channel_key function to send the Channel Key
1832 * Added silc_server_create_channel_key to create new channel key. The
1833 channel key is now re-generated everytime someone joins or leaves
1834 a channel, as protocol dictates. Note: channel->key_len is the
1837 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1840 packet_receive.[ch] to separate packet sending and receiving
1841 routines. The server.[ch] now includes everything else including
1842 actual packet processing (writing and reading data) and other
1845 Renamed silc_server_private_message_send_internal to
1846 silc_server_send_private_message. The routine is still though
1847 used only to relay private messages as server does not send
1848 private messages itself.
1850 Renamed silc_server_new_channel to silc_server_create_new_channel
1851 and added new function sicl_server_new_channel that handles the
1852 incoming New Channel packet. Added also new sending function
1853 silc_server_send_new_channel to send New Channel Payload.
1855 * Added new function silc_server_notify to process incoming notify
1856 packet to the server/router. Server may then relay the notify
1857 to clients if needed.
1859 * Added new function silc_server_new_channel_user to process incoming
1860 New Channel User packet. Router will redistribute the packet and
1861 send JOIN notify to its local clients and locally connected servers
1862 if needed. Normal server will send JOIN notify to its local client
1863 on same channel when received this packet. Added also corresponding
1864 sending function silc_server_send_new_channel_user to sent the
1867 * Added boolean route argument to send_notif_to_channel and
1868 packet_send_to_channel functions to attempt to route the packet
1869 if it is TRUE and send only locally if it is FALSE.
1871 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * silc_server_replace_id now broadcasts the received replace ID
1874 packet if it is not broadcast packet already. The router must
1875 broadcast to inform other routers about changed ID.
1877 * Added backpointer to server's router into SilcServer context in
1878 silcd/server_internal.h.
1880 * Fixed silc_server_packet_broadcast to send correct broadcast
1883 * The channel key is now distributed to the local client as soon
1884 as it is received from the router (in router environment) so that
1885 no other packet may be sent for the channel until client has
1888 * silc_server_remove_channel_user now broadcasts the received
1889 Remove Channel User packet if it is not broadcast packet already.
1890 The router must broadcast to inform other routers about removed
1893 * Added users field into SilcPacketContext that is a reference count
1894 of the context. One can increase the reference count by calling
1895 silc_packet_context_dup which is now changed to just increase the
1896 reference count instead of duplicating the data. The reference
1897 count is decresed by calling silc_packet_context_free that will
1898 free the data after the reference count hits zero.
1900 For now on the packet context and everything allocated into it
1901 (including the raw packet from network) must be freed by calling
1902 the new silc_packet_context_free function. Added also new function
1903 silc_packet_context_alloc that must be used now to allocate the
1904 context. This also means that if a routine is asynchronous from
1905 silc_[client/server]_packet_parse_type the packet context must
1906 be duplicated by calling silc_packet_context_dup. Otherwise it
1907 gets free'd after silc_[client/server]_packet_parse_type returns.
1908 Also, one must remember that if packet is duplicated then its
1909 reference count must be decresed by calling the free function as
1910 many times as it was duplicated.
1912 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1913 from both client and server.
1915 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Made joining to a channel working in router environment.
1919 * Cleaned up JOIN command on server side and create function
1920 silc_server_command_join_channel internal routine to make the
1923 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Changed silc_command_pending list to SilcDList. Also, added
1926 `ident' field to SilcServerCommandPending structure to identify
1927 the reply and to call correct callback.
1929 Added silc_server_command_pending_check function to replace the
1930 corresnponding macro. The silc_command_pending list is not
1933 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1934 to set identifier to previously allocated Command Payload. It
1935 is used to set identifier for command when resending Command
1938 * Added silc_command_payload_encode_payload to encode Command
1939 Payload buffer from SilcCommandPayload structure.
1941 * Added silc_argument_payload_encode_payload to encode Argument
1942 payload buffer from SilcArgumentPayload structure.
1944 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Changed WHOIS command to support router connection on server side.
1947 The whois request is always sent to router unless the server is
1948 standalone server. After server has received the reply from the
1949 router will it send the reply to the client.
1951 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1952 broadcast received broadcast packet. The function is used only
1953 by router. The broadcast packet is always sent to the router's
1956 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1957 render given ID to printable string, for log files for example.
1959 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Made basic router to router connections working. At least they
1962 can now connect to each other but nothing really works the way
1963 they are supposed - yet.
1965 * Added new initiator token to RouterConnection configuration
1966 file in silcd/serverconfig.[ch]. It is used to tell whether we
1967 are the initiator to the remote router or whether we'll expect
1968 the other end to connect.
1970 * Moved registering of listener task to silc_server_init, hence
1971 the server starts listenning as soon as it is run, even if it
1972 does not have connections to other routers. Let's see how well
1975 * Changed default connection retry timeouts for more suitable in
1978 * Removed cipher and such arguments from silc_idlist_add_client
1979 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1980 Added new function silc_idlist_add_data to add the keys and stuff
1983 * Added SilcIDListData structure and added it to SilcClientEntry
1984 and SilcServerEntry as their first field in the structure. This
1985 way we can explicitly cast the ID entries to the SilcIDListData
1986 structure and get common data for the entries. In past, we had
1987 to first check what type of connection it is and then cast it to
1988 correct ID entry type. Now, we can directly cast the opaque
1989 pointer to the SilcIDListData (no matter what ID entry it actually
1990 is) and get the data needed.
1992 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1995 in some circumstances even if threre were timeout tasks, though not
1996 IO tasks, but tasks anyway. Now fixed.
1998 * Defined SilcServerConnection structure to hold connection specific
1999 stuff about directly connected servers and routers. The definition
2000 is currently in silcd/server_internal.h. I thought about having
2001 a bit more important role fro this struct but for now it is used
2002 only when connecting to other server (or router actually).
2004 * Added connecting retry support in server when connecting to
2005 router(s). The retry feature implement exponential backoff
2006 algorithm. Also, added SilcServerParams structure to hold default
2007 parameters for server. For now, it include these retry settings
2008 and are hard coded. After server is moded to be as Silc Server
2009 Library this structure will be more important.
2011 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Changed client librarys channel->clients table to SilcList and
2014 changed code accordingly.
2016 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Changed client's channel table to SilcList and changed code
2019 accordingly. Also changed SilcChannelClientEntry to include back-
2020 pointer to the channel so that client entry can use that structure
2021 as list as well and we have fast cross-reference to the channel.
2022 This change dramatically decreased the complexity of channel
2023 handling with client entry and vice versa (removed one extra
2024 loop when searching for channel entry from many functions).
2026 * Changed server->sim from table to SilcDList and changed code
2029 * NAMES command can now be used from user interface. It will show
2030 the user list on the channel, neatly.
2032 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2033 Code now saves realname of the user if it becomes available.
2035 * Renamed configure.in to configure.in.pre and made ./prepare
2036 script to automatically add correct version string to
2037 configure.in which it creates from configure.in.pre.
2039 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * NAMES command reply now shows users mode with the nickname when
2044 * Moved silc_client_ch[u]mode[_char] functions from
2045 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2046 place sucks, they are utility functions and should be in some
2049 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2051 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2054 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Added TRQ (efficient deque and list library) into lib/trq. This is
2059 a very good list library that is currently used in the SILC. Defined
2060 SilcList API over the library because I didn't like the API very
2061 much. See lib/trq/silclist.h for the API and examples of how to
2062 use the API. Fixed various places in the code to use the new
2063 SilcList API. The SilcList is meant for lists that has a structure
2064 already defined as a list. It is not suitable to add just some
2065 context to the list (in TRQ, the context is the list actually).
2067 So, I defined SilcDList that can be used for the purpose where
2068 predefined list structure does not exit. This can be used as
2069 such list. Now some context just can be added to the SilcDList.
2070 Currently this list is not used in the SILC just yet, though there
2071 are a lot places where this can replace dynamically allocated
2072 tables and I will fix these places, later, to use SilcDList.
2073 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2074 and use TRQ internally).
2076 Also fixed some annoying warning messages that the original TRQ
2077 code generated. Also minor changes to TRQ's Makefile.in.
2079 * Added support for querying by Client ID to both WHOIS and
2080 IDENTIFY commands into server, as required by the protocol.
2082 * Removed method function pointers from SilcBuffer structure. They
2083 weren't used to anything and just increased the context size for
2084 no good reason. This change also made silc_buffer_alloc and
2085 silc_buffer_free functions inline functions.
2087 * Disabled command flooding detection support until it's fixed so
2088 that it accepts commands in but does not execute them more than once
2091 * Added silc_net_localhost(), to return local hostname, into
2092 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2093 that must be initialized before calling silc_client_init.
2095 * Added new function: silc_server_send_notify_on_channels to send
2096 notify messages to all channels client has joined. It is assured
2097 that the message is sent only once per client.
2099 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2100 lib/silcutil/silcutil.[ch] as silc_format function. The new
2101 function is generic and is used by server as well, not only by
2102 the logging routines.
2104 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2105 the provided version string was not acceptable. Added new function:
2106 silc_ske_check_version into lib/silcske/silcske.h. The function
2107 must be implemented by the application (client or server) and it
2108 does not reside in the SKE library. The function checks the version
2109 string remote end sent.
2111 * Added back pointers (to opaque context and to SilcSocketConnection)
2112 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2114 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2115 duplicate packet context structure.
2117 * Changed `notify' client operation to send same arguments as client
2118 receives from server except for ID's. ID's are mapped to correct
2119 ID entry and that is returned. Also, if channel entry is not sent
2120 by server but the notify is for channel the channel entry is sent
2121 to application (otherwise application doesn't know that it is for
2122 channel (library gets it from packet's Destination ID)).
2124 * Added silc_client_remove_from_channels into client library to
2125 remove a client from all channels it has joined to. Used when
2126 received SIGNOFF notify from server. Added also new function
2127 silc_client_replace_from_channels to replace old ID entry with
2128 new ID entry on all channels. Used when received NICK_CHANGE
2131 * Fixed ID Cache list handling in silc_idlist_get_client in
2132 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2133 to get (or query) client by ID.
2135 * Updated TODO list.
2137 * Added connection authentication status message defined by the
2138 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2139 support for these into the code in client and server side.
2141 * Added generic function silc_client_send_command to send any command
2142 with variable argument list. Application should use this function
2143 to send commands if the command functions provided by the library
2144 does not suite for the application's user interface needs.
2146 * Added new `failure' client operation. Application is notified about
2147 received failure packet if client is executing a protocol. In this
2148 case the protocol's execution has failed.
2150 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2151 is required by the protocol.
2153 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2154 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2157 * Added status flag to SilcSKE object to indicate realtime status
2158 of the SKE protocol.
2160 * Application receives now exactly same command reply arguments as
2161 the library receives from server. However, if ID is received the
2162 corresponding ID entry is returned to the application (eg. Client
2163 ID is mapped to correct SilcClientEntry entry and that is returned).
2164 Changed command_reply client operation due to this change.
2166 * Changed all ID's in commands and in command replys as ID Payloads.
2167 Change affected both client and server side codes.
2169 All ID's sent in SILC network (with execption of ID's in SILC
2170 Packet header) are sent in ID Payload to support variable length
2173 * Server now notifies nick changes and notifies all clients on
2174 the channels about the new nickname (about the new Client ID,
2177 * Implemented CMODE command to change channel modes. Supports all
2178 channel modes defined by the protocol specs except ban and invite
2179 lists. (Also, private channel key mode is supported but support for
2180 setting private channel key in client is missing, thus, this mode
2181 has no effect on client side (except that server requires that the
2182 client uses private channel key and normal channel traffic does not
2185 Also, invite mode works per se, but INVITE command does not work
2186 yet correctly, so you can set channel as invite only channel but
2187 inviting clients to the channel does not work (it is yet to be
2188 thought what's the best way to do it).
2190 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2191 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2192 Implemented CUMODE command to change user's mode on the channel.
2193 Supports all modes defined by the protocol specs.
2195 * Added NAMES command reply to return users modes on the channel.
2197 * Removed unnecessary and slow ciphers from lib/silccrypt.
2199 * Set SO_KEEPALIVE option to connection sockets by default.
2201 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2203 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2204 redefined the Notify Payload into protocol specs.
2206 * Added silc_id_payload_parse_id to get ID directly from raw
2209 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2212 accept searching by Client ID as well.
2214 * Added support for LEAVE and SIGNOFF notify types in client library.
2216 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2217 to parse ID Payload from raw data.
2219 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Added flags parameter into silc_ske_assemble_security_properties
2222 function in lib/silcske/silcske.[ch].
2224 * Changed notify client operation to fit better for notify messages
2225 sent by server. The notify payload received from server is now
2226 passed to the application (after parsing it to SilcNotifyPayload).
2227 It is application's responsibility to retrieve the arguments
2228 from the payload and show the message the way it wants. The message
2229 sent by server is implementation specific.
2231 * Changed public keys to comply with the protocol specification.
2232 Old public keys are not supported anymore and are not compatible.
2234 * Removed nickname from Channel Payload as the latest draft removed
2235 it. The client must resolve the nickname from the NAMES command
2236 reply received when it joined the channel.
2238 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2240 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Fixed some errors in protocol specification drafts.
2244 * Created lib/silccore/silcnotify.c to implement Notify Payload
2245 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2246 generic payloads described by protocol specifications. The file
2247 includes implementations for ID Payload and Argument Payload.
2249 * Changed Command Payload implementation to use the new Argument
2250 Payload. Changed command_xxxx_payload to command_payload_xxxx
2251 to comply with SILC coding conventions.
2253 * Added suppport for Argument Payload handling in Notify Payload
2254 implementation as protocol requires it. Added the new support
2255 into server and client lib as well.
2257 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Added support for multiple nicknames on same channel. [n] is
2260 added locally to the nickname if there are more than one same
2261 nicknames on the channel.
2263 * Server now sends all nicknames that matched WHOIS request.
2264 Client also shows the list received from server.
2266 * Added TOPIC command to client side. User can now set and show
2267 current topic on channel.
2269 * Added MOTD command to client and server. Also, server sends the
2270 motd when client connects to the server.
2272 * Changed version strings to comply ISO 8601.
2274 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Fixed protocol error handling in client library. It should now
2277 cope even if the SKE fails for some reason.
2279 * Made new protocol specification drafts for submitting to IETF.
2281 * Implemented TOPIC command to server in silcd/command.c.
2283 * Added two new notify types into lib/silccore/silcnotify.h:
2284 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2285 notify nickname change and topic setting/change on a channel.
2287 * API change of command_reply operation in client library. The
2288 application gets now the status type received from server as well.
2290 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2294 * Cras fixed and optimized the packet handling even further and
2295 it should work now. Minor change to the prototype of function
2296 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2298 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Added new function into lib/silcutil/silcschedule.[ch]:
2301 silc_schedule_with_fd to select() a specified fd. The function
2302 returns after timeout expires or data arrives or goes. The
2303 function is used by packet routines to wait that all data is
2304 received from network.
2306 * Fixed data reading from network in lib/silccore/silcpacket.c.
2307 The code now assures that all data is read from the fd and then
2308 continues packet processing. This was a bug fix since the code
2309 used to drop some data in some circumstances.
2311 * Added new function into lib/silcclient/client.[ch]:
2312 silc_client_start_key_exchange to start key exchange after
2313 connection has been established to server. The code internally
2314 now uses this funtion but its main purpose was to provide it
2315 for applications that perform their own connecting. After
2316 application has created a connection it merely calls this
2317 function to start the key exchange between client and server.
2318 The library takes care of everything else after that.
2320 Updated also lib/silcclient/README to explain the usage of
2323 * Do not send to application information that connection has
2324 been established. Application gets notified it by connect
2327 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Applied cras's patch to add silc_schedule_one function. The
2330 function runs scheduler once and returns.
2332 * Fixed the scheduler after cras messed it up. The timeout
2333 handling works now as it's supposed to work.
2335 * Added into lib/silccore/ silcnotify.h to include notify
2336 message types support. Changed silc_server_send_notify*
2337 functions, in server.[ch], to support those new notify types.
2338 Added the support for the notify types into client library,
2339 as well. Added new notify client operation into ops.h in
2342 * Changed silc_server_packet_send_to_channel to send normal
2343 packets instead of just channel message packets. The function
2344 is now used to send the notify packets to channels. It is not
2345 used to send channel message packets anymore, as server never
2348 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2349 va_arg()s as it seems to require it nowadays. I guess, if SILC
2350 is compiled with older va_arg() the new code should work anyway.
2352 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Splitted core library. Core library (lib/silccore) includes
2355 now only SILC protocol specific core (and common) components.
2356 Created new utility library (lib/silcutil) that includes more
2357 generic purpose stuff. The stuff for util library was taken
2358 from the old core library. This was minor and easy split.
2360 * Created SILC Client Library (lib/silcclient) that includes
2361 implementation of the SILC client without user interface. This
2362 was major move from silc/ directory. The code has been changed
2363 so that it is transparent towards the user interface. The
2364 silc/ directory includes now the same user interface as before
2365 and it uses the new client library. Read lib/silcclient/README.
2366 Basicly, the client library performs everything else related
2367 to SILC except user interface handling. Also, configuration
2368 files are considered to be part of user interface and library
2369 does not handle them.
2371 This change also changed a lot of structures, function naming etc.
2372 Most important change was that SilcClientWindow object was
2373 renamed to SilcClientConnection in the client library. Created
2374 also new file lib/silcclient/ops.h. Also added new files
2375 silc/local_command.[ch] and silc/client_ops.[ch].
2377 All these changes were made to make it easier for user interface
2378 designers to create what ever user interface for the SILC client
2381 It is also expected that the server will be moved to lib
2382 directory as well and SILC Server Library will be created;
2383 sometimes in the future.
2385 * Removed Local commands from lib/silccore/silccommand.h as
2386 they are application specific and new client library does not
2387 handle any of those anymore.
2389 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2390 old client implementation in silc/.
2392 * Added support for callback functions in SILC_LOG_* macros.
2393 Application can now set its own callbacks that will be called
2394 instead of using the default functions that will always print
2395 the debug messages to stderr (or stdout). Also, debugging can
2396 now be disabled by setting silc_debug to FALSE and re-enabled by
2397 setting it to TRUE. Note, that logging will still work even
2398 if debugging is disabled.
2400 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2401 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2402 silc_log_reset_debug_callbacks.
2404 * To enable debugging in silc client one must give now -d
2405 option on command line.
2407 * Changed silc_schedule_init to automatically allocate task queues
2408 if they are not allocated before calling it.
2410 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Added GMP 3.1 into math library.
2414 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2417 a channel in SILC network. The packet is used by servers and
2418 routers to notify other routers that user has left a channel.
2419 This little feature was missing until now. Added the feature
2420 to protocol specification as well.
2422 Added functions: silc_server_send_remove_channel_user and
2423 silc_server_remove_channel_user into server.[ch].
2425 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2426 lib/silccore/silcpacket.h. However, they are not implemented
2429 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Fixed joining to a channel and sending channel messages
2432 between server and router. The channel message sending should
2433 now work inside a cell.
2435 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Fixed the private message sending between server and router.
2438 The private message sending should now work inside a cell.
2440 * Added silc_server_replace_id into server.[ch] to replace
2441 existing ID in the SILC network.
2443 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2444 and silc_idlist_replace_server_id into idlist.[ch] in server.
2446 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Fixed the server to server connections. Server can again now
2449 connect to router. Router to router connections probably does
2452 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Added dynamic protocol registering support. Now protocols can
2455 registered and unregistered on the fly. Patch by cras.
2457 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Added lib/contrib directory to hold routines that some platforms
2460 don't have but are needed by SILC.
2462 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2463 into lin/contrib to provide getopt() and getopt_long() for
2464 those who don't have it.
2466 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Added AWAY command to client. When away message is set and
2469 client receives a private message packet the client automatically
2470 replies to the sender with the away message.
2472 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2473 bug seemed to be the cause of recent problems when compiling
2476 * Added version detection support to SKE protocol specification
2477 and added the new changes to the SKE implementation as well.
2478 There were other minor changes in the SKE protocol as well.
2480 Many changes in lib/silcske/silcske.[ch] and in
2481 lib/silcske/payload.[ch].
2483 * Added ^U functionality, clear input line. Patch from cras.
2485 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Mainly small bugfixes on core library. Fixed some debugging
2488 logging and buffer overflow in silclog.c.
2490 * Updated config.sub and config.guess on the distribution tree.
2492 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Added command lagging support in server. Client may execute
2495 commands now only once in two seconds.
2497 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Optimized packet reception. MAC computation and checking is now
2500 also more optimized. A lot previously duplicated code is now
2501 used as generic by both client and server.
2503 * Fixed key pair generation in clientutil.c
2505 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added into lib/silccore/silcbufutil.[ch] new function;
2508 silc_buffer_realloc.
2510 * Moved generic packet sending/encryption functions to
2511 lib/silccore/silcpacket.[ch] from client and server. Some
2512 rewriting of the functions.
2514 * Moved all generic packet reception/decryption functions to
2515 lib/silccore/silcpacket.[ch] from client and server. The
2516 packet processing is now much cleaner in both client and server.
2517 These were major changes in both client and server.
2519 * Created many common functions in server to do packet sending.
2520 Previously code were duplicated a lot, this has been removed
2523 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Rewrote major parts of the ID cache system. Don't know
2526 whether it is better now or not but at least the API is more
2529 * Major rewrite on ID cache stuff on client because of the ID
2530 cache API changes. Added idlist.c to client.
2532 * Also major rewrite on ID cache stuff on server as well.
2533 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2534 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2535 in hand, instead they are all put into the ID cache system now.
2536 All server_idlist_* routines uses ID cache now instead of
2537 traversing its own lists (those lists does not exist anymore).
2538 SilcIDList though still exists. Also, SilcXXXEntry's are
2541 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Finally made the SKE implementation compliant to the protocol
2544 specification. All mp integers are now binary encoded as
2545 opposed being HEX encoded.
2547 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2550 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2551 functions: silc_[encode/decode]_pem. Also added function
2552 silc_encode_pem_file to PEM encode with newlines ('\n') for
2555 * SILC public keys are now encoded either PEM or binary. Same
2556 option is for private keys as well. By default private keys
2557 are binary encoded and public keys PEM encoded. Silly HEX
2558 encoding were removed.
2560 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2561 function to create fingerprints.
2563 * Fixed a bug in SHA1; does not change the original data anymore.
2565 * Partly implemented INFO command on client and server side.
2566 Fixed CLEAR command. Changes to SERVER command; show current
2567 server(s) when giving command without arguments. Added
2568 VERSION command to client.
2570 * Added check to server that unregistered connections cannot
2571 execute commands (unless it is specificly allowed).
2573 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Fixed screen refresh.
2577 * Fixed channel joining bug from client. On some circumstances
2578 client tried to join to a channel it had already joined.
2580 * Added public key verification process into client's protocol.c.
2581 The client now verifies the public key from user and saves
2582 it into ~./silc/serverkeys/ directory.
2584 Added into: clientutil.[ch]: silc_client_verify_server_key.
2586 * Changed SKE protocol's silc_ske_initiator_finish function
2587 to accept callback function that verifies the received public
2588 key. Removed old silc_ske_verify_public_key function.
2590 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2593 silc_pkcs_private_key[_data]_set.
2595 * Made the password and public authentication more cleaner in
2596 server's protocol.c.
2598 * Removed historic and obsolete protocol `channel_auth' from
2599 both client and server.
2601 * Removed wrong way of sending command status messages from
2602 server to client in server's command.c. The old way violated
2603 protocol specification.
2605 Changes to silccore/silccommand.[ch]: removed
2606 silc_command_encode_status_payload -> not needed anymore,
2607 changed silc_command_encode_payload_va to accept extra
2608 argument on variable argument list. The argument type must
2609 now be provided to the function. Also, added new function:
2610 silc_command_encode_reply_payload_va which is same as
2611 normal command_encode_payload_va except command status type
2612 is provided as extra argument.
2614 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Added ~./silc directory handling. The directory includes the
2617 public and private keys for the client.
2619 Added silc_client_check_silc_dir, silc_client_create_identifier
2620 and silc_client_load_keys.
2622 * Implemented SILC protocol compliant public key. Added public
2623 and private key saving to and loading from files.
2625 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2626 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2627 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2628 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2629 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2631 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2632 silc_pkcs_load_[public/private]_key.
2634 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added silc_server_get_route (route.[ch]) to get connection
2637 data for the fastest route for given ID.
2639 * Implemented INVITE command on client and server. The command
2640 were re-defined in the SILC Protocol Specification and the
2641 implementation now complies with the specification.
2643 * Implemented PING command on client and server.
2645 * Implemented NAMES command on client and server. The server side
2646 supports currently only normal server not router server yet.
2647 Some changes to NAMES definition in SILC protocol specification.
2649 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Implemented LEAVE command on client and server.
2653 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2654 again. This change was made to the protocol as well. Server
2655 should not violate the protocol specification anymore.
2657 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2660 was tested. SOCKS4 was not but should work anyway.
