1 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * If re-key protocol is active then process the incoming packets
4 synchronously since we must assure that icoming packets encrypted
5 with the old key is processed before the new keys is set to
6 use. This is true other packets than for REKEY packets.
7 Affected file silcd/server.c. The same was done to client library
8 as well, affected file lib/silcclient/client.c.
10 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Fixed bug in client and server to accept the force send if
13 the packet is send from silc_[server/client]_packet_process
14 function. Otherwise the packets are never delivered, oops.
16 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
18 * Disable force sending of packets when REKEY protocol is active.
19 We must assure that no packet is sent directly when rekey is
20 performed. All packets must be sent through packet queue.
21 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
22 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
23 function is silc_[server/client]_packet_send_real to check
26 * Replaced the SIM paths from example config files to
27 /usr/local/modules. Also, make install creates now
28 /usr/local/silc/logs directory to hold all the SILC server
31 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Made the configure.in.pre work on Solaris. Patch by salo.
35 * Made all ciphers compatible with non-x86 machines. Defined
36 CBC mode macros into lib/silccrypt/ciphers_def.h.
38 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
40 * Fixed the make install.
42 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * When MAC computation fails the silc_packet_decrypt returned 0
45 even though it was supposed to return -1. Fixed this. The
46 affected file is lib/silccore/silcpacket.c.
48 * Do not replace the config files in /etc/silc (in make install)
49 if they already exist. Affected file ./Makefile.am.
51 * Do not send re-key packets immediately but through packet queue.
52 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
54 * Changed silc_net_check_host_by_sock to return FALSE if the
55 IP/DNS could not be resolved. Though, it returns the IP address
56 now even if it could not resolve it (but returns also FALSE).
57 Affected file lib/silcutil/silcnet.[ch].
59 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Added silc_pkcs_decode_identifier to decode the public key's
62 identifier. Affected file lib/silccrypt/silpkcs.[ch].
63 Added also silc_pkcs_free_identifier. Added also new context
64 SilcPublicKeyIdentifier.
66 * Added -S option to the silc client. It is used to dump the
67 contents of the specified public key file.
69 * Changed the PKCS api to return the public key length when
70 setting the public key.
72 * Fixed a fatal bug in the public and private key file loading.
73 Affected file lib/silccrypt/silcpkcs.c.
75 * Execute the packet parsing for client with zero (0) timeout
76 if the protocol is active. Affected file silcd/server.c.
78 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Made the key generation options to the silcd program. Added
81 -C option, equivalent to client's option.
83 * Added new [ServerKeys] config section to the server. It
84 configures the server's public and private key.
86 * Defined generic Public Key Payload into the protocol
87 specification to send specific type of public keys and
90 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
91 public key or certificate.
93 * Implemented the GETKEY command to the server and to the
94 client library and on user interface.
96 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Made preliminary `make install' work.
100 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Added SilcServerRekey context into silcd/idlist.h.
104 * Added the PFS support as defined in the specification to the
105 SKE protocol. Affected files lib/silcske/*.c.
107 * Added `ske_group' field to the SilcServerRekey context to hold
108 the number of the SKE group that is used with PFS in re-key.
109 Affected file silcd/idlist.h.
111 * Added PFS re-key support to the server. Affected file is
114 * Added silc_protocol_cancel to cancel execution of the next
115 state of the protocol. Affected file is
116 lib/silccore/silcprotocol.[ch].
118 * Added the re-key support with and without PFS to the client
119 library. Re-key is performed once in an hour, by default.
121 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
122 Added silc_client_rekey_callback and silc_client_rekey_final.
123 Affected files are lib/silcclient/protocol.[ch] and
124 lib/silcclient/client.[ch].
126 * Removed the `hmac_key' and `hmac_key_len' fields from the
127 SilcClientConnection structure; not needed. Affected file is
128 lib/silcclient/client.h.
132 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
134 * Do not ask whether user wants to use the negotiated private key
135 for private messages, just use it. Affected file is
136 silc/local_command.c.
138 * Added `send_enc_key' and `enc_key_len' fields to the
139 SilcIDListData structure since they are needed in the re-key
140 phase. Affected file is silcd/idlist.[ch].
142 * Implemented the simple re-key protocol into the server.
143 Affected files silcd/server.c and silcd/protocol.[ch]. The
144 re-key will be performed once in an hour, by default.
146 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
147 Added silc_server_rekey, silc_server_rekey_callback and
148 silc_server_rekey_final.
150 * Removed Tunneled flag from the protocol. Updated the code
151 and the specifications.
153 * Adde `pfs' field to the SilcIDListData to indicate whether
154 the PFS is to be performed in the re-key. Affected file is
157 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
160 int64 of at least the xintXX size. If void * is less that 4
161 bytes uint32 * will be used. Defined bool as boolean.
163 * Changed _ALL_ unsigned long and unsigned int to uint32,
164 unsgined short to uint16 in the source tree.
166 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
167 not handle clients that has entry->data.registered == FALSE.
168 They are not in the network anymore. Affected file is
171 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
173 * Implemented the sending of the SERVER_SIGNOFF notify in the
174 server. Affected file is silcd/server.c.
176 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
177 Added also silc_notify_payload_encode_args into the
178 lib/silccore/silcnotify.[ch].
180 * Implemented ther SERVER_SIGNOFF notify handling in the server.
181 Affected file silcd/packet_receive.c.
183 * Implemented the SERVER_SIGNOFF notify handling in the client
184 library. Affected file lib/silcclient/client_notify.c. Also,
185 implemnted the printing of the SERVER_SIGNOFF info to the
186 application. Affected file silc/client_ops.c.
188 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
189 if the deleting was successful. Affected file silcd/idlist.[ch].
191 * Added support for public key authentication in the connection
192 authentication protocol in the client library. Affected file
193 lib/silcclient/protocol.c.
195 * Changed the server's silc_idlist_get_clients_by_* interface
196 to support already allocated array so that new entries may be
197 added to pre-allocated array. Affected file silcd/idlist.[ch].
198 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
201 * All command reply functions in the server now calls the
202 pending command callback even if error occured. This way the
203 error will be delivered to the client as well. Affected files
204 silcd/command.c and silcd/command_reply.c.
206 * Fixed INFO command to return local server's info if no server
207 was provided. Affected file lib/silcclient/command.c.
209 * Removed RESTART command for good. Updated the code and the
212 * Rewrote parts of the task system. It is a bit simpler now.
213 Removed unsued task priorities. The affected files are
214 lib/silcutil/silctask.[ch].
216 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Moved the USERS printing from the library to the application.
219 Affected files lib/silcclient/command.c and silc/client_ops.c.
221 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added channel key re-key support. The re-key is perfomed
226 only by the router and is done once in an hour. Added `rekey'
227 field to the SilcChannelEntry in the server. Affected files
228 silcd/server.c and silcd/idlist.h.
230 * Added silc_task_unregister_by_context into the file
231 lib/silcutil/silctask.[ch].
233 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Added SILC_UMODE_GONE mode to indicate when the client is not
236 present in the SILC network. Added also support to the local
237 command AWAY that will set this mode. Added support of showing
238 "xxx is gone" in WHOIS command. The USERS command shows the
241 * Fixed setting server and router operator privileges in the
242 server's UMODE command. Affected file silcd/command.c.
244 * Merged the SKE KE1 and KE2 payloads into one payload. The
245 new KE payload is equivalent to the old KE2 payload.
247 Cleaned up the SKE Start Payload parsing. It now uses the
248 simple buffer unformatting to do the parsing. A lot faster
251 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
252 to the SKE that is used to indicate whether both of the SKE
253 parties should perform authentication. By default only the
254 responder performs authentication. By setting this flag also
255 the initiator must do authentication. By default it is unset
256 since in normal SKE case, client to server connection, only
257 the responder should do authentication. When doing SKE between
258 two clients both should perform authentication. Updated the
259 code and the protocol specs.
261 * A little fix to IDENTIFY command in the server. Search the
262 client first by hash not nickname. Affected file is
265 * Fixed the silc_client_close_connection to support closing
266 the client to client connections wihtout deleting too much
267 data. Affected file lib/silcclient/client.c.
269 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
270 are received if protocol used to be active but is not anymore
271 the application would crash due to NULL pointer dereference.
272 Affected files silcd/server.c and lib/silcclient/client.c.
274 * Added `hash' field to the SilcClientConnection to include
275 the hash function negotiated in the SKE protocol.
277 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
278 to set the channel founder authentication data. A client can
279 claim the founder rights later by providing the authentication
280 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
281 This way the channel founder can regain the channel founder
282 privileges even it is left the channel. This works only on
283 local server and the client must be connected to the same
284 server to be able to regain the founder rights. Updated the
285 protocol specs accordingly.
287 Added support to the CMODE command in the client to set the
288 founder auth data. Read the README to see how to set it.
290 Added support to the CUMODE command to claim the founder
291 rights. Read the README to see how to do it.
293 Added support for the founder authentication to the Channel
294 Entry in the server. Affected file silcd/idlist.h.
296 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
297 server's CMODE command. Affected file silcd/command.c.
299 * Added the following new functions into lib/silccore/silcauth.[ch]:
300 silc_auth_get_method and silc_auth_get_data.
302 * The server now saves the remote hosts public key to the
303 SilcIDListData pointer. Affected file silcd/protocol.c.
305 * The normal server now does not remove the channel entry from
306 the cache if the founder authentication data is set. It used
307 to remove it if the founder was the last one on the channel on
308 the server and left the channel. The auth data is saved and
309 if the channel is re-joined later the old entry is used with
310 the old auth data. Affected files silcd/command_reply.c and
313 * Removed the `pkcs' field from the SilcIDListData structure
314 in the server; it is not used. Affected file silcd/idlist.h.
316 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Fixed packet processing on slow links. Partial packets were
319 never re-processed because the incoming data buffer was cleared
320 by the application. Application must not directly clear the
321 sock->inbuf, the packet processing routines handle it. Fixed
322 this in client library and in server.
324 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Fixed the WHOIS and IDENTIFY send reply function to really
327 check whether to send list or just one entry. Affected file
330 * Cleaned up the LEAVE command's channel key distribution. The
331 affected file silcd/command.c.
333 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
334 can enforce the channel mode as well. In that case the ID
335 includes the ID of the server. The code now enforces the
336 mode change if the router have different mode than the server.
338 * The notify client operation with CMODE_CHANGE notify can now
339 return NULL client_entry pointer if the CMODE was not changed
340 by client. Application must check for this.
342 * Added <Server ID> argument to INFO command to support server
343 info fetching by Server ID.
345 * Added silc_server_announce_get_channel_users to get assembled
346 packets of channel users of the specified channel. Affected
347 file silcd/server.[ch].
349 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
350 was freed underneath the ID Cache.
352 * Re-announce clients when the server received CHANNEL_CHANGE
353 notify from the router. Affected file silcd/packet_send.c.
355 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
358 crashed since it did not handle the fact that there is no cipher
359 called "3" and didn't check the error condition. Now fixed.
361 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
362 flag. It can be used to send message requests.
364 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Implemented the RESTART command in the client.
368 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
369 notice type messages. Added notice printing to the user
372 * The channel keys are not re-generated if the channel's mode
373 is PRIVKEY, ie private key on the channel exists. Affected
374 files silcd/server.c and silcd/command.c.
376 * Fixed a little bug in channel message delivery when channel
377 private keys are set in the server. Affected file is
380 * Changed the setting on channel->on_channel = TRUE from the
381 silc_client_save_channel_key to the JOIN command reply. The
382 key payload is not received if the private channel key is set.
383 Affected file lib/silcclient/command_reply.c and the
384 lib/silcclient/client_channel.c.
386 * When the CMODE_CHANGE notify is sent and the channel private
387 key mode is removed the channel key must be re-generated in
388 other cells as well. Added this support for the router in the
389 silcd/packet_receive.c.
391 * Added new local command NOTICE to send notice message on
392 channel. Affected file silc/local_command.[ch].
394 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Added new local command ME to the client. It is used to send
397 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
398 some action. Affected file silc/local_command.[ch].
400 * Changed channel_message and private_message client operations
401 to deliver the message flags to the application. Added also
402 the `flags' arguments to the silc_client_send_channel_message
403 and silc_client_send_private_message functions. Affected file
406 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
408 * Redefined the Private Message Payload to support private message
409 keys and to support the new private message flags. Updated
410 the protocol specs. Flags makes it possible to have for example
413 * Added new type SilcPrivateMessagePayload and defined an API
414 for it in the lib/silcclient/silcprivate.[ch].
416 * Tested private message private keys successfully. Tested the
417 private message key set, unset and list commands with the new
420 * Redefined the Channel Message Payload to include the channel
421 message flags (equal with private message flags) to support
422 for example CTCP style messages.
424 * Defined some of the message (for channel and private message)
425 flags. Updated the protocol specs and added the flags to the
426 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
428 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Added SilcKeyAgreementStatus type to the key agreement routines
431 to indicate the current status and error if one occured.
432 The status types are defined in the lib/silcclient/silcapi.h.
434 * Added new local command KEY that is used to set and unset private
435 keys for channels, set and unset private keys for private messages
436 with remote clients and to send key agreement requests and
437 negotiate the key agreement protocol with remote client. The
438 key agreement is supported only to negotiate private message keys,
439 it currently cannot be used to negotiate private keys for channels,
440 as it is not convenient for that purpose.
442 * Fixed a minor pending callback setting bug in the function
443 silc_client_get_client_by_id_resolve, now the function works.
444 Affected file lib/silcclient/idlist.c.
446 * Added function silc_net_get_local_port to get local bound
447 port by socket. Added to lib/silcutil/silcnet.[ch].
449 * Added `sockets' and `sockets_count' fields to the SilcClient
450 object. They hold the sockets of the listenning sockets in
451 the client. Listenning sockets may be for example the key
452 agreement server. Affected file lib/silcclient/client.[ch].
453 Added functions the silc_client_add_socket and the
454 silc_client_del_socket. They are exported to the application
457 * Added ~./silc/clientkeys to support other client's public keys.
459 * Renamed verify_server_key client operation to verify_public_key
460 and added one argument to indicate the type of the connection
461 (server, client etc.).
463 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
465 * Added silc_server_connection_auth_request to handle the
466 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
467 silcd/packet_receive.[ch].
469 * Added silc_server_send_connection_auth_request into the
470 silcd/packet_send.c to send the connection auth request packet.
472 * Cleaned up the silcd/protocol.c a bit and fixed some memory
475 * Fixed the public key authentication in responder side in the
476 server. The `auth_data' pointer includes the SilcPublicKey
477 not the path to the public key. Affected file silcd/protocol.c.
479 * Implemented the public key authentication in the initiator side
480 in the server. Affected file silcd/protocol.c.
482 * Removed the [RedirectClient] config section from the server
483 configuration. Is not needed and I don't want to implement it.
485 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * Cleaned up the CMODE command in the server. It now works
488 correctly and supports all the modes defined in the protocol.
489 Affected file is silcd/command.c.
491 * Added `hmac_name' field to the SilcChannelEntry in the server
492 to hold the default HMAC of the channel. It can be set when
493 creating the channel (with JOIN command). Affected files
496 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
497 type to indicate the change of the current cipher and hmac
498 on the channel. Client can safely ignore the <cipher> argument
499 (if it chooses to do so) since the CHANNEL_KEY packet will
500 force the channel key change anyway. The <hmac> argument is
501 important since the client is responsible of setting the new
502 HMAC and the hmac key into use.
504 * Fixed the CMODE command in the client library as well.
506 * Tested CMODE command in router environment successfully.
508 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Show the version of the remote client (or server) when connecting
511 to the server. It is logged to the log file. Affected file
514 * Fixed the KILLED notify handling in the client library. The
515 client must be removed from all channels when receiving the
518 Also, do not remove the client entry when giving the KILL
519 command but when the KILLED notify is received.
521 * Removed silc_idlist_find_client_by_nickname from the server.
522 Not needed anymore. Affected files silcd/idlist.[ch].
524 * Implemented the CHANNEL_CHANGE notify type handling to the
525 server. Affected file silcd/server.c.
529 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Added silc_server_send_notify_invite to send the INVITE
532 notify between routers.
534 * Implemented the INVITE command correctly to the server.
536 * Implemented the INVITE notify type handling in the server.
538 * Implemented the INVITE command to the client library and on the
541 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Added function silc_server_get_client_resolve to find the
544 client entry by ID from all ID lists and then resolve it
545 (using WHOIS) if it cannot be found. Affected file is
548 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Implemented the BAN command to the client library.
552 * The JOIN command in the server now checks the invite list
555 * Changed the silc_command_reply_payload_encode_va and the
556 silc_command_payload_encode_va to support that if argument is
557 NULL it ignores and checks the next argument. Affected file
558 lib/silccore/silccommand.c.
560 * Added silc_server_send_notify_ban to send the BAN notify
561 type between routers.
563 * Chaned the silc_notify_payload_encode to support that if
564 argument is NULL it ignores and checks the next argument.
565 Affected file lib/silccore/silcnotify.c.
567 * Tested ban lists in router environment successfully.
569 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Implemented BAN command to the server, in silcd/command.[ch].
573 * Removed the BAN and INVITE_LIST modes from the CMODE command
576 * Added function silc_string_match to regex match two strings.
577 Affected files lib/silcutil/silcutil.[ch].
579 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Redefined parts of the SilcChannelEntry in the server to support
582 the new ban and invite lists.
584 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Redefined the INVITE command. The same command can be used to
587 invite individuals to the channel but also to manage the invite
588 list of the channel (to add to and remove from the invite list).
589 Updated the protocol specs.
591 * Added new command SILC_COMMAND_BAN that can be used to manage
592 the ban list of the channel. Updated the protocol specs.
594 * Removed the channel modes: the SILC_CMODE_BAN and the
595 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
596 in the CMODE command. The equivalent features are now available
597 using INVITE and BAN commands. Updated the protocol specs.
599 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
600 in the network about change in the current ban list. The notify
601 type is not used by the client.
603 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
604 support the invite lists.
606 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Added new function silc_string_regexify that converts string
609 including wildcard characters into regex string that can
610 be used by the GNU regex library. Added into the file
611 lib/silcutil/silcutil.[ch].
613 Added silc_string_regex_combine to combine to regex strings
614 into one so that they can be used as one regex string by
615 the GNU regex library. Added into the file
616 lib/silcutil/silcutil.[ch].
618 Added silc_string_regex_match to match two strings. It returns
619 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
621 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Imported GNU regex to the soruce tree into lib/contrib.
624 Fixed some compiler warning from the regex.c.
626 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Fixed MOTD command in the server to work in router environment.
630 * Fixed the MOTD command in the client library to support
631 the server argument in the command.
633 * Added `nickname_len' argument to the silc_idlist_add_client
634 in the server, as the `nickname' argument may be binary data
637 * Added silc_idlist_get_channels to return all channels from
640 * Implemented LIST command to the server. Affected file is
643 * Implemented the LIST command to the client library and on the
646 * Added [<user count>] argument to the LIST command reply.
647 With private channels the user count is not shown.
649 * Updated TODO and README.
651 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * The client entry's data.registered must be TRUE even with
654 global client entry on global client list. The data.registered
655 is used to check whether the client is anymore in the network,
656 for example with WHOWAS command so it must be valid.
658 * Fixed the WHOWAS command in the server. It now actually works
659 in router environment. Added function into silcd/command_reply.c
660 silc_server_command_reply_whowas_save.
662 * Added silc_idlist_purge function to the silcd/idlist.c
663 to periodically purge the ID Cache.
665 * Fixed INFO command in the server. It works now in router
666 environment. Added <server name> argument to the INFO command
667 reply. Updated the protocol specs.
669 * Fixed minor bug in silc_idcache_purge to not purge if the
670 expire value is zero.
672 * Fixed various bugs in WHOIS and IDENTIFY command handling as
673 they were buggy because of the WHOWAS information.
675 * Fixed local command MSG to handle the async resolving of
676 the remote client properly. It used to fail the first MSG.
677 Affected file silc/local_command.c.
679 * Added `data_len' field to SilcIDCache context.
681 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Update TODO. Todo in commands in the server.
685 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
688 used by routers as broadcast packet to inform other routers
689 about the changed user mode.
691 Implemented the notify handling in the server. Affected file is
692 silcd/packet_receive.c. Added the function
693 silc_server_send_notify_umode to the silcd/packet_send.[ch].
695 * Added new generic Channel Payload and deprecated the New Channel
696 Payload. The New Channel Payload is now the generic Channel
699 * Added new argument `mode' to the silc_server_send_new_channel
700 as it is required in the Channel Payload now.
702 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
703 and created a new and real SilChannelPayload to represent the
704 new generic Channel Payload. Implemented the encode/decode
705 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
707 * Added silc_server_get_client_channel_list to return the list
708 of channels the client has joined for WHOIS command reply.
709 Affected file silcd/server.[ch].
711 * Implemented the channel list sending in the WHOIS command reply
712 in server and in the client.
714 Implemented the channel list displaying on the user interface
715 as well. Affected file silc/client_ops.c.
717 * Added silc_channel_payload_parse_list to parse list of Channel
718 Payloads. It returns SilcDList list of SilcChannelPayloads.
719 Client for example can use this function to parse the list of
720 channels it receives in the WHOIS command reply. The caller
721 must free the list by calling silc_channel_payload_list_free.
722 Affected files lib/silccore/silcchannel.[ch].
724 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Added one new argument <user mode> to the WHOIS command reply
727 to return the mode of the user in SILC. Updated the protocol
730 Implemented it to the server and client.
732 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Fixed the mode printing on the user interface on joining.
735 Affected file silc/client_ops.c.
737 * Implemented the UMODE command and user modes in general to the
738 client library and to the user interface.
740 * Implemented the UMODE command to the server.
742 * The server now sends UNKNOWN_COMMAND error status if client sends
743 unknown command. Affected file silcd/command.c.
745 * All server commands now handle the command identifier the right
746 way when sending the command reply to the client. The client can
747 use to identify the command replies with the identifier.
749 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Added silc_server_get_client_route to resolve the route to
752 the client indicated by the client ID. Affected file is
755 * Added silc_server_relay_packet as general function to relay
756 packet to arbitrary destination. This deprecates functions
757 like _send_private_message_key, _relay_notify etc. Affected
758 file is silcd/packet_send.[ch].
760 Removed silc_server_send_key_agreement,
761 silc_server_send_private_message_key and
762 silc_server_packet_relay_notify functions from the file
763 silcd/packet_send.[ch].
767 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
768 server. Affected file silcd/packet_receive.[ch].
770 * Implemented the KILL command to the client. Implemented the
771 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
772 Affected files lib/silcclient/command[_reply].c and
773 lib/silcclient/client_notify.c. Implemented the KILL notify
774 printing in the user inteface.
776 * Fixed a lot silc_parse_nick memory leaks from the client
777 library in the file lib/silcclient/command.c.
779 * Changed the silc_server_send_notify_on_channels's `sender'
780 argument from SilcSocketConnection to SilcClientEntry to
781 check the sender as entry and not as connection object and not
782 to send to the client provided as argument. The affected file
783 is silcd/packet_send.[ch].
785 * The notify packets that are destined directly to the client used
786 to not to be processed by the server. Now changed that and the
787 server processes all notify packets. After relaying the packet
788 to the client the notify packet is processed in the server.
790 * The silc_server_free_client_data now checks whether there is
791 pending outgoing traffic for the client and purges the data to
792 the network before removing the client entry.
794 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
796 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
797 an client is killed from the SILC Network. Updated the protocol
800 Added new function silc_server_send_notify_killed to the
801 silcd/packet_send.[ch].
803 * Added function silc_server_packet_relay_notify to relay notify
804 packets that are destined directly to a client. In this case
805 the server does not process the notify packets but merely relays
806 it to the client. Affected file silcd/packet_send.[ch].
808 Added also silc_server_packet_process_relay_notify to check
809 whereto relay the notify. Affected file is
810 silcd/packet_receive.[ch].
812 * Implemented the KILL command to the server.
816 * Added the backup schema desgined last fall to the protocol
817 specs for everyone to see. The specification is in the
818 *-spec-xx.txt draft and the packet type definitions for the
819 backup routers is in *-pp-xx.txt draft. Thusly, added also
820 new packet type SILC_PACKET_CELL_ROUTERS.
822 * A big security problem in the implementation discovered. The
823 signoff of an client did not cause new channel key generation
824 which it of course should've done. The channel keys must be
825 always re-generated when client leaves (or signoffs) the channel.
826 The silc_server_remove_from_channels funtion now handles
827 the channel key re-generation.
829 * Added `sender' argument to the silc_server_send_notify_on_channels
830 to not to send the client provided as argument. Affected file
831 silcd/packet_send.[ch].
833 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Implemented OPER and SILCOPER commands into the server and
838 * Added silc_auth_verify and silc_auth_verify_data to verify
839 the authentication directly from the authentication payload.
840 It supports verifying both passphrase and public key based
841 authentication. Affected file lib/silccore/silcauth.[ch].
843 * Added `hash' field to the SilcIDListData structure. It is the
844 hash negotiated in the SKE protocol. Affected file is
847 * Slight redesigning of the SilcAuthPayload handling routines.
848 Do not send SilcPKCS but SilcPublicKey as argument.
850 * Implemented the public key authentication support to the
851 serverconfig. The public key is loaded from the provided path
852 and saved as authentication data to void * pointer. Thus,
853 changed the unsigned char *auth_data to void *auth_data;
855 * Fixed SHUTDOWN command to send the reply before the server
856 is shutdown. :) Affected file silcd/command.c.
858 * Fixed fatal bug in CONNECT command. The hostname was invalid
859 memory and server crashed. Affected file silcd/command.c.
861 * Fixed fatal bug in CLOSE command. The server_entry became
862 invalid but was referenced later in the command. Affected file
865 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Fixed fatal bug in failure packet handling. Server ignored
868 the failure and thus crashed when it came.
872 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
875 that the command may be executed only once in (about) 2 seconds.
876 The old SILC_CF_LAG flag is same but allows command bursts up
877 to five before limiting.
879 Added the support for CF_LAG and CF_LAG_STRICT flags to the
880 server code. Various commands now includes the CF_LAG_STRICT
881 flag to disallow any kind of miss-use of the command.
883 * Fixed the silc_buffer_unformat to not to allocate any data
884 if the length of the data is zero. It used to allocate the
885 length + 1. Affected file lib/silcutil/silcbuffmt.c.
887 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Changed the format of AdminConnection configuration section
890 in the server. Added username of the admin to the format.
891 Affected files silcd/serverconfig.[ch].
893 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
894 to return admin configuration data by host, username and/or
897 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Implemented WHOWAS command to the server. Added the functions:
901 silc_server_command_whowas_parse,
902 silc_server_command_whowas_send_reply,
903 silc_server_command_whowas_from_client and
904 silc_server_command_whowas_from_server
906 * Added <Client ID> argument to the WHOWAS command reply. Updated
907 the protocol specs accordingly.
909 * Implemented WHOWAS command and command_reply to the client
912 Implemented the WHOWAS printing on the user interface.
914 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added new argument to the WHOWAS command reply, the real name.
917 It is an optional argument. Updated the protocol specs.
919 * Added SilcIDCacheDestructor callback that is registered when
920 the SilcIDCache is allocated. The callback is called when
921 an cache entry in the ID Cache expires, or is purged from the
922 cache. Added into lib/silccore/idcache.[ch].
924 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
925 to destruct the client entries when the cache entry expires.
926 Other ID Cache's in server and in the client library ignores
929 * If the ID Cache entry's `expire' field is zero then the entry
930 never expires. Added boolean `expire' argument to the
931 silc_idcache_add function in the lib/silccore/idcache.[ch].
932 If it is TRUE the default expiry value is used.
934 * Added silc_server_free_client_data_timeout that is registered
935 when client disconnects. By default for 5 minutes we preserve
936 the client entry for history - for WHOWAS command.
938 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Added support to the server to enforce that commands are not
941 executed more than once in 2 seconds. If server receives
942 commands from client more frequently, timeout is registered
943 to process the commands. Affected file silcd/command.c.
944 Added new function silc_server_command_process_timeout.
946 * Changed NICK_NOTIFY handling in client library to check that
947 if the client's nickname was changed, so there is no need to
948 resolve anything from the server.
950 * Removed error printing from the WHOIS and IDENTIFY commands.
951 If error occurs then it is ignored silently in the client library.
952 The application, however, may map the received error to
953 human readable error string. The application currently maps
954 the NO_SUCH_NICKNAME error to string.
956 * Made the command status message public to the application. Moved
957 them from lib/silcclient/command_reply.c to
958 lib/silcclient/command_reply.h. The application can map the
959 received command status to the string with the
960 silc_client_command_status_message function.
962 * Added check to the server to check that client's ID is same
963 as the Source ID in the packet the client sent. They must
966 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Added dist-bzip hook to the Makefile.am to make bzip2
969 compressed distributions.
971 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Server now enforces the maximum length for the nickname and
974 the channel as protocol specification dictates. 128 bytes for
975 nickname and 256 bytes for channel name.
977 * Moved the WHOIS printing to the application. The client libary
978 does not print out the WHOIS information anymore, the application
979 must do it. Renamed silc_client_command_reply_whois_print to
980 the silc_client_command_reply_whois_save.
982 The client's idle time is also sent to the application now, and
983 the idle is shown on screen.
985 * Added silc_client_command_reply_identify_save to save the
986 received IDENTIFY entries.
988 * Do not check for channel private keys in message sending and
989 reception if the channel does not have the PRIVKEY mode set.
990 Affected file lib/silclient/client_channel.c.
992 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
995 just surfaced after chaning the JOIN procedure.
997 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Added silc_client_get_clients_by_list to get client entries
1000 from Client ID list, that is returned for example by JOIN
1001 and USERS command replies. The application should use this
1002 function for example when JOIN command reply is received to
1003 resolve the clients already on the channel (library does not
1004 do that anymore as USERS command reply is not used in the JOIN
1005 procedure anymore). Affected files lib/silcclient/silcapi.h and
1006 lib/silcclient/idlist.c.
1008 * JOIN command reply and USERS command reply returns now SilcBuffer
1009 pointers instead of unsigned char pointers when returning
1010 the client list and mode list.
1012 * Added <Client ID> argument to the JOIN command reply, mainly
1013 for the server to identify for which client the command was
1014 originally sent. Updated protocol specs accordingly.
1016 * Added SilcDlist private_key pointer to the SilcChannelEntry
1017 in the client to support the channel private keys. Affected
1018 file is lib/silcclient/idlist.h.
1020 * Added SilcChannelPrivateKey argument to the function
1021 silc_client_send_channel_message so that application can choose
1022 to use specific private ke if it wants to. If it is not provided,
1023 the normal channel key is used, unless private keys are set.
1024 In this case the first (key that was added first) is used
1025 as the encryption key.
1027 * Implemented the support for channel private key handling.
1028 Implemented the following functions:
1030 silc_client_add_channel_private_key,
1031 silc_client_del_channel_private_keys,
1032 silc_client_del_channel_private_key,
1033 silc_client_list_channel_private_keys and
1034 silc_client_free_channel_private_keys
1036 Affected file lib/silcclient/client_channel.c.
1038 * Added the support for the private keys in the channel message
1039 sending and encryption and in the message reception and
1040 decryption. Affected funtions are
1041 silc_client_send_channel_message and silc_client_channel_message.
1043 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * Added SKE's key verify callback to the client library's
1046 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1048 * Removed the statement that server (or router) must send USERS
1049 command reply when joining to the channel so that the client
1050 knows who are on the channel. Instead, the client list and
1051 client's mode list is now sent in the JOIN command reply to the
1052 client who joined channel. This is better solution.
1054 * Added function silc_server_get_users_on_channel and function
1055 silc_server_save_users_on_channel to the silcd/server.[ch].
1057 * Removed function silc_server_command_send_users from the
1060 * Do not show topic on the client library anymore. The topic is
1061 sent in the command reply notify to the application and the
1062 application must show the topic now.
1064 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added client searching by nickname hash into the IDENTIFY and
1067 WHOIS commands in the server as they were clearly missing from
1068 them. Affected file is silcd/command.c.
1070 * Fixed a bug in private message receiving in the client library.
1071 The remote ID was freed and it wasn't supposed, now it is
1074 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Minor fix to the channel payload; allocate the data area, as it
1077 needs to be of specific length.
1079 * If the key agreement port is zero then the operating
1080 system will define the bound port. Affected files are
1081 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1083 * Added new function silc_channel_payload_decrypt into the file
1084 lib/silccore/silcchannel.[ch].
1086 * Moved the channel message etc, check from silc_packet_decrypt
1087 to applications. The library calls now a generic
1088 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1089 when the packet is either normal or special. This was done to
1090 allow more wide range of checking that was not allowed when
1091 the code was in library. Now applications can do virtually any
1092 checks to the packet and return to the library the decision how
1093 the packet should be processed. Affected files are
1094 lib/silccore/silcpacket.[ch].
1096 Added silc_server_packet_decrypt_check to the server and
1097 silc_client_packet_decrypt_check to the client library.
1099 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1100 to send with specified source and destination information.
1102 * Channel message delivery between routers was broken after the
1103 channel key distribution was fixed earlier. The channel key
1104 was used be to distributed to other routers as well which is not
1105 allowed by the protocol. Now this is fixed and channel keys
1106 really are cell specific and the channel message delivery between
1107 routers comply with the protocol specification.
1109 * Fixed various commands in server to check also the global list
1110 for the channel entry and not just the local list. The affected
1111 file silcd/command.c.
1113 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Added assert()s to buffer formatting and unformatting routines
1116 to assert (if --enable-debug) when error occurs. Affected
1117 file: lib/silcutil/silcbuffmt.c.
1119 * Changed to auto-reconnect to check whether the remote host is
1120 router and register the re-connect timeout if it is. It used
1121 to check that whether we are normal server, but router must do
1122 auto-reconnect with another router as well. Affected file
1125 * Removed the [<key len>] option from CMODE command as the cipher
1126 name decides the key length, nowadays. See the defined ciphers
1127 from the protocol specification.
1129 * Added [<hmac>] option to the CMODE command to define the HMAC
1130 for the channel. Added SILC_CMODE_HMAC channel mode.
1132 * Added [<hmac>] option for the JOIN command so that user can
1133 select which HMAC is used to compute the MACs of the channel
1136 * Added Hmac field to the Channel Message Payload. The integrity
1137 of plaintext channel messages are now protected by computing
1138 MAC of the message and attaching the MAC to the payload. The
1139 MAC is encrypted. Now, it is clear that this causes some
1140 overhead to the size of the packet but rationale for this is that
1141 now the receiver can verify whether the channel message decrypted
1142 correctly and also when private keys are set for the channel the
1143 receiver can decrypt the packet with several keys and check from
1144 the MAC which key decrypted the message correctly.
1146 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1147 lib/silccrypt/silccipher.[ch].
1149 * Added silc_hash_len to return the digest length into the
1150 lib/silcrypt/silchash.[ch].
1152 * Rewrote parts of Silc Channel Payload interface in the
1153 lib/silccore/silcchannel.[ch]. The encode function now also
1154 encrypts the packet and parse function decrypts it.
1156 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Fixed a minor formatting bug in the SKE's key material processing.
1159 It actually might have processed the keys wrong way resulting
1162 * Redefined the mandatory HMAC algorithms and added new algorithms.
1163 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1164 and hmac-md5 truncated to 96 bits. The mandatory is now
1165 hmac-sha1-96. Rest are optional (including the one that used
1166 to be mandatory). Rationale for this is that the truncated HMAC
1167 length is sufficient from security point of view and can actually
1168 make the attack against the HMAC harder. Also, the truncated
1169 HMAC causes less overhead to the packets. See the RFC2104 for
1172 * Added new [hmac] configuration section. The SKE used to use
1173 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1174 is of course wrong. The official names that must be proposed in
1175 the SKE are the ones defined in the protocol specification
1176 (hmac-sha1-96 for example). The user can configure any hmac
1177 using any hash function configured in the [hash] section. At
1178 least, the mandatory must be configured.
1180 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1182 * Added HMAC list to the SKE proposal list. It has now both
1183 hash algorithm list and HMAC list. This makes the protocol
1184 incompatible with previous versions. The SKE now seems to work
1185 the way it is supposed to work, for the first time actually.
1187 * Defined plain Hash algorithms to the protocol specification.
1190 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Implemented support for key agreement packets into the server.
1193 Added functions silc_server_key_agreement and
1194 silc_server_send_key_agreement. Other than these functions,
1195 server has nothing to do with this packet.
1197 * Added support for private message key packets into the server.
1198 Added functions silc_server_private_message_key and
1199 silc_server_send_private_message_key.
1203 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1204 called in the protocol's final callback instead in the END
1205 protocol state. This makes a little more sense and in the same
1206 time in client we can use the same protocol routines for normal
1207 key exchange and to key agreement packet handling as well.
1209 * Added to both client's and server's KE protocol context the
1210 SilcSKEKeyMaterial pointer to save the key material. We will
1211 bring the key material to the protocol's final callback by doing
1212 this. The final callback must free the key material.
1214 * Added SKE's packet_send callback into client's KE protocol
1215 context so that the caller can choose what packet sending function
1216 is used. This way we can use different packet sending when
1217 doing normal SKE when doing key agreement packet handling (in
1218 the key agreement packet handling we do not want to encrypt
1221 * Implemented the responder side of the key agreement routines
1222 in the client. The client can now bind to specified port and
1223 accept incoming key negotiation. The key material is passed
1224 to the application after the protocol is over.
1226 * Implemented the processing of incoming Key Agreement packet
1227 in the client. Added function silc_client_key_agreement to
1230 * Implemented the intiator side of the key agreement routines
1231 in the client. The client can now initiate key agreement with
1232 another remote client. The key material is passed to the
1233 application after the protocol is over.
1235 * Created client_keyagr.c to include all the key agreement
1238 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1239 SILC_TASK_CALLBACK except that it is not static.
1241 * Created client_notify.c and moved the Notify packet handling
1242 from the client.[ch] into that file.
1244 * Created client_prvmsg.c and moved all private message and
1245 private message key routines from the client.[ch] into that file.
1247 * Create client_channel.c and moved all channel message and
1248 channel private key routines from the client.[ch] into that file.
1250 * Changed silc_client_get_client_by_id_resolve to resolve with
1251 WHOIS command instead of IDENTIFY command, in the file
1252 lib/silclient/idlist.c.
1254 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Implemented the SKE's responder side to the Client library.
1258 * When FAILURE is received to the protocol do not trust it
1259 blindly. Register a timeout to wait whether the remote closes
1260 the connection as it should do it, only after that process the
1261 actual failure. This was changed to both client and server.
1263 * Added client_internal.h to include some of the structures
1264 there instead of client.h in lib/silcclient/.
1266 * Added function silc_task_unregister_by_callback to unregister
1267 timeouts by the callback function.
1269 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Some "Incomplete WHOIS info" errors has been appearing on the
1272 log files. Took away the entry->userinfo check from WHOIS
1273 reply sending. The entry->userinfo is now " " if client did not
1274 provide one. I thought this was fixed earlier but something
1275 is wrong still. Let's see if the error still appears.
1277 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Fixed a minor bug in the login when the channel key is
1280 re-generated in the server. It used to generate the key in
1281 wrong order and thus caused problems in the channel traffic.
1283 * Fixed a minor bug in channel key distsribution after
1284 KICK command. The key was not sent to the router even though
1287 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Added silc_ske_process_key_material_data as generic routine
1290 to process any key material as the SILC protocol dictates. The
1291 function is used by the actual SKE library but can be used by
1292 applications as well. This relates to the private message keys
1293 and the channel private keys since they must be processed the
1294 same way the normal SILC session keys. The protocol dictates
1295 this. Affected files: lib/silcske/silcske.[ch].
1297 Added also silc_ske_free_key_material to free the
1298 SilcSKEKeyMaterial structure.
1300 * Defined silc_cipher_set_key function to set the key for
1301 cipher without using the object's method function. The affected
1302 files: lib/silccrypt/silccipher.[ch].
1304 * Implemented silc silc_client_add_private_message_key,
1305 silc_client_add_private_message_key_ske,
1306 silc_client_del_private_message_key,
1307 silc_client_list_private_message_keys and
1308 silc_client_free_private_message_keys functions in the
1311 Added functions silc_client_send_private_message_key to send
1312 the Private Message Key payload and silc_client_private_message_key
1313 to handle incoming Private Message Key payload.
1315 * Added Cipher field to the Private Message Key payload to set
1316 the cipher to be used. If ignored, the default cipher defined
1317 in the SILC protocol (aes-256-cbc) is used.
1319 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Removed lib/silcclient/ops.h file.
1323 Redefined parts of the SILC Client Library API. Created new
1324 file silcapi.h that deprecates the ops.h file and defines the
1325 published Client Library API. Defined also private message key
1326 API and channel private key API into the file.
1328 This is the file that the application must include from the
1329 SILC Client Library. Other files need not be included by
1330 the application anymore.
1332 * Added new key_agreement client operation callback and also
1333 defined the Key Agreement library API for the application.
1335 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1338 is used by clients to request key negotiation between another
1339 client in the SILC network. If the negotiation is started it
1340 is performed using the SKE protocol. The result of the
1341 negotiation, the secret key material, can be used for example
1342 as private message key.
1344 Implemented the Key Agreement payload into the files
1345 lib/silccore/silauth.[ch].
1347 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Redefined ciphers for the SILC protocol. Added some new ciphers
1350 and defined the key lengths for the algorithms. Changed the
1351 code accordingly. The default key length is now 256 bits.
1353 * Fixed SKE key distribution function silc_ske_process_key_material
1354 when the key length is more than 128 bits. The default key
1355 length in SILC is now 256 bits.
1357 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1358 to indicate unsupported algorithm.
1360 * Renamed rijndael.c to aes.c and all functions as well.
1362 * Fixed a long standing channel key setting bug in client library.
1363 Weird that it has never surfaced before.
1365 * Fixed bug in channel deletion. If the entire channel is removed
1366 then it must also delete the references of the channel entry
1367 from the client's channel list as the client's channel entry and
1368 the channel's client entry share same memory.
1370 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Implemented CONNECT and SHUTDOWN commands in the client.
1374 * Implemented CLOSE command to the client.
1376 * Added the function silc_idlist_find_server_by_name into the
1377 files silcd/idlist.[ch].
1379 Added the function silc_idlist_find_server_by_conn into the
1380 files silcd/idlist.[ch].
1382 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * DIE command was renamed to SHUTDOWN. Updated the both code
1387 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1388 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1390 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1393 * Added function silc_server_create_connection function to create
1394 connection to remote router. My server implementation actually
1395 does not allow router to connect to normal server (it expects
1396 that normal server always initiates the connection to the router)
1397 so the CONNECT command is only good for connecting to another
1400 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1403 or some other client was kicked from the channel.
1405 Implemented the handling of the notify type to both client
1408 Implemented silc_server_send_notify_kicked to send the KICKED
1409 notify. It is used to send it to the server's primary router.
1411 * Implemented the KICK command into server and client.
1413 * Added `query' argument to the silc_idlist_get_client function
1414 to indicate whether to query the client from server or not if
1417 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1418 to indicate that the client is not channel founder.
1422 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Removed the rng context from SilcPacketContext structure and
1425 changed that the packet routine uses the Global RNG API.
1427 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Added support for quit message that client can "leave" on the
1430 channel when it quits the SILC. It is ditributed inside the
1431 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1433 Added silc_server_free_client_data that will take the
1434 signoff message as argument.
1436 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1438 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Updated parts of the protocol specification to keep it up
1443 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1446 payloads in one packet.
1448 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1449 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1450 use now the new List flag.
1452 * Also deprecated the following packet types: REPLACE_ID,
1453 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1455 * Added list support for Notify packet in server.
1457 * Added silc_server_send_notify_channel_change to send the
1458 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1459 the silc_server_send_replace_id.
1461 * Added silc_server_send_notify_nick_change to send the
1462 NICK_CHANGE notify type. Deprecates the function
1463 silc_server_send_replace_id.
1465 * Added silc_server_send_notify_join to send the JOIN notify type.
1466 Deprecates the function silc_server_send_new_channel_user.
1468 * Added silc_server_send_notify_leave to send LEAVE notify type.
1469 Deprecates the function silc_server_send_remove_channel_user.
1471 * Added silc_server_send_notify_cmode and
1472 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1473 types. Deprecates the silc_server_send_set_mode function.
1475 * Added SERVER_SIGNOFF notify type to indicate that server has
1476 quit. This means that all clients on the channel from that
1477 server will drop. This can be also used when netsplit happens.
1479 Deprecated REMOVE_ID packet type since it is not needed anymore
1482 Added silc_server_send_notify_server_signoff to send the
1483 SERVER_SIGNOFF notify type. Deprecates the function
1484 silc_server_send_remove_id.
1486 Added also silc_server_send_notify_signoff to send the
1487 SIGNOFF notify type.
1489 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1490 SILC protocol from this day on. Changed the protocol
1491 specification as well.
1493 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1494 notify type. It is used between routers to notify about
1495 topic changes on a channel.
1497 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1500 * Partly updated the protocol specification to comply with the
1501 changes now made. It is still though a bit outdated.
1503 * The JOIN notify type now takes one extra argument <Channel ID>.
1504 The packet used to be destined to the channel but now the
1505 JOIN type may be sent as list thus it is impossible to
1506 destine it to any specific channel. By adding this argument
1507 it is again possible.
1509 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Added CREDITS file. The CHANGES and CREDITS file will appear
1512 in the distribution as well.
1514 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1516 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1517 types in the server's silcd/packet_receive.c.
1519 * Implemented CMODE and CUMODE to work in router environment.
1521 * Fixed minor encoding and decoding buglet from the
1522 lib/silccore/silcmode.c.
1524 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1527 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1529 * Changed all SilcConfigServer* and silc_config_server* to
1530 SilcServerConfig* and silc_server_config*, respectively.
1533 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Associated the ID (client or server ID) to the Authentication
1536 Payload to avoid any possibility of forging. Updated the
1537 protocol specification and the code accordingly.
1539 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * The RSA key length is now save to the RsaKey context in the
1542 key generation process in lib/silccrypt/rsa.c. The key length
1543 is now used to figure out the maximum size of the block allowed
1544 to be encrypted/signed.
1546 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1547 is equivalent to the silc_mp_mp2bin but does not allocate any
1550 * Changed silc_mp_mp2bin API to take length argument. If it is
1551 non-zero then the buffer is allocated that large. If zero, then
1552 the size is approximated using silc_mp_sizeinbase, which however
1555 * Created Global RNG API which is global RNG that application can
1556 initialize. After initializing, any routine anywhere in the
1557 code (including library) can use RNG without allocating a new
1558 RNG object. This was done to allow this sort of use of the
1559 RNG in code that has no chance to allocate RNG object. All
1560 applications currently allocate this and many routines in the
1561 library use this. Affected file lib/silccrypt/silcrng.[ch].
1563 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1564 it to use the Global RNG API.
1566 * Defined Authentication Payload into protocol specification that
1567 is used during SILC session to authenticate entities. It is
1568 used for example by client to authenticate itself to the server
1569 to obtain server operator privileges.
1571 Implemented this payload into the lib/silccore/silcauth.[ch].
1572 Implemented also routines for public key based authentication
1573 as the new protocol specification dictates.
1575 Moved definitions of different authentication methods from
1576 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1578 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1579 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1580 silc_pkcs_verify_with_hash functions into the file
1581 lib/silccrypt/silcpkcs.[ch].
1583 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1585 * The client entry's userinfo pointer must be always valid.
1586 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1587 will fail since it requires the userinfo. Now, the userinfo
1588 is allocated as "" if actual userinfo does not exist. Actually,
1589 it must exist and it is totally Ok to drop client connections
1590 that does not announce the userinfo. However, we will make
1591 this workaround for now.
1593 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1594 to return the remote port by socket.
1596 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1599 SILC_SERVER_PENDING_EXEC and added an new macro
1600 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1601 data or when error occurs while processing the pending command.
1603 Added new argument `destructor' into silc_server_command_pending
1604 and to the SilcServerCommandPending object. This destructor is
1605 now called after calling the pending callback or if error occurs
1606 immediately. If error occurs the actual pending callback won't
1607 be called at all - only the destructor. The destructor may be
1608 NULL if destructor is not needed.
1610 All this applies for client library code as well. Similar
1611 changes were made there as well for the pending commands.
1613 In the client, the application must now allocate the
1614 SilcClientCommandContext with the silc_client_command_alloc
1617 * Added reference counter to the SilcServerCommandContext. Added
1618 function silc_server_command_alloc and silc_server_command_dup
1621 Same type of functions added to the client library for the same
1624 * Removed the cmd_ident from IDListData away since it is now
1625 global for all connections. It is the command identifier used
1626 in command sending and with pending commands. The affected file
1629 * Added reference counter to the SilcSocketConnection objecet to
1630 indicate the usage count of the object. The object won't be
1631 freed untill the reference counter hits zero. Currently only
1632 server uses this, and client ignores it. The client must be
1633 set to use this too later. The affected files are
1634 lib/silccore/silcsockconn.[ch]. Added also the function
1635 silc_socket_dup to increase the reference counter.
1637 This was mainly added because it is possible that the socket
1638 is removed underneath of pending command or other async
1639 operation. Now it won't be free'd and proper DISCONNECTING
1640 flags, etc. can be set to avoid sending data to connection that
1641 is not valid anymore.
1643 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1644 the connection. After that it sets SILC_SET_DISCONNECTED.
1645 It is, however, possible that the socket data is not still freed.
1646 The silc_server_packet_process now checks that data is not
1647 read or written to connection that is DISCONNECTED. The socket
1648 get's freed when the reference counter hits zero.
1650 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Changed the client operation API: channel_message operation's
1653 `sender' is now the client entry of the sender, not the nickname
1654 and the `channel' is the channel entry, not the channel name.
1656 In the private_message operation the `sender' is now also the
1657 client entry of the sender not the nickname.
1659 Affected file is lib/silcclient/ops.h and all applications
1660 using the client operations.
1662 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Moved the calling of ops->connect() from connect_to_server_final
1665 into receive_new_id functin since that is the point when the
1666 client is actually allowed to send traffic to network. The
1667 affected file is lib/silcclient/client.c.
1669 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1672 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1673 (if needs broadcasting) instead of broadcasting the packets one
1674 by one which would make a burst in the network traffic.
1676 * Added `broadcast' argument to the functions in silcd/server.[ch]
1677 silc_server_create_new_channel[_with_id] to indicate whether
1678 to send New Channel packet to primary router.
1680 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Added new function into the silcd/server.[ch] files:
1683 silc_server_create_new_channel_with_id to create new channel with
1684 already existing Channel ID.
1686 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1687 lib/silccore/silcpacket.h. This packet is used t send list of
1688 Set Mode payloads inside one packet. Server uses this to set
1689 the modes for the channels and clients on those channels, that it
1690 announced to the router when it connected to it. The protocol
1691 specification has been updated accordingly.
1693 * The silc_server_new_channel did not handle the packet coming
1694 from normal server as it normally does not send that. However,
1695 when it announces its channels it does send it. Implemented
1696 the support for that.
1698 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1699 into the file lib/silccore/id.h.
1701 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * Fixed memory leaks in the functions silc_idlist_del_client,
1704 silc_idlist_del_channel and silc_idlist_del_server in the file
1705 silcd/idlist.c. All of those leaked like a sieve.
1707 * Fixed some small memory leaks in the client's function
1708 silc_client_notify_by_server.
1710 * Added functions into silcd/server.c: silc_server_announce_clients,
1711 silc_server_announce_channels and silc_server_announce_server.
1712 These functions are used by normal and router server to announce
1713 to its primary router about clients, channels and servers (when
1714 router) that we own. This is done after we've connected to the
1717 These functions effectively implements the following packet types:
1718 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1719 and SILC_PACKET_NEW_ID_LIST.
1721 * Added new functions into the silcd/packet_receive.[ch]:
1722 silc_server_new_id_list, silc_server_new_channel_list and
1723 silc_server_new_channel_user_list to handle the incoming
1724 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1726 * Added support of changing Channel ID in the function
1727 silc_server_replace_id. If the server that announces a channel
1728 to the router already exists in the router (with same name but
1729 with different Channel ID), router is responsible to send
1730 Replace ID packet to the server and force the server to change
1731 the Channel ID to the one router has.
1733 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1734 client that the Channel ID has been changed by the router. The
1735 normal server sends this to the client. Client must start using
1736 the new Channel ID as the channel's ID.
1738 Implemented handling of this new type into lib/silcclient/client.c
1739 into the function silc_client_notify_by_server.
1741 * Added new function silc_idlist_replace_channel_id into the files
1742 silcd/idlist.[ch] to replace the Channel ID.
1744 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1746 * Call silc_server_command_identify_check always when processing
1747 the IDENTIFY command in silcd/command.c
1749 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1752 send keepalive packets. The packet can be sent by clients,
1753 servers and routers.
1755 Added function silc_socket_set_heartbeat into the file
1756 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1757 If not set, the heartbeat is not performed. The actual
1758 heartbeat is implemented in the low level socket connection
1759 library. However, application is responsible of actually
1762 Added silc_server_send_heartbeat to send the actual heartbeat
1763 packet into silcd/packet_send.[ch]. Server now performs
1764 keepalive with all connections.
1766 * Added silc_task_get_first function into lib/silcutil/silctask.c
1767 to return the timeout task with shortest timeout. There was a bug
1768 in task unregistration that caused problems. TODO has been
1769 updated to include that task system must be rewritten.
1771 * The client library will now resolve the client information when
1772 receiving JOIN notify from server for client that we know but
1773 have incomplete information.
1775 * Rewrote parts of silc_server_remove_from_channels and
1776 silc_server_remove_from_one_channel as they did not remove the
1777 channel in some circumstances even though they should've.
1779 * Encryption problem encountered in server:
1781 The LEAVE command used to send the Channel Key packet to the
1782 router immediately after generating it. However, the code
1783 had earlier sent Remove Channel user packet but not immediately,
1784 ie. it was put to queue. The order of packets in the router
1785 was that Channel Key packet was first and Remove Channel User
1786 packet was second, even though they were encrypted in the
1787 reverse order. For this reason, MAC check failed. Now, this
1788 is fixed by not sending the Channel Key packet immediately but
1789 putting it to queue. However, this is more fundamental problem:
1790 packets that are in queue should actually not be encrypted
1791 because packets that are sent immediately gets encrypted
1792 actually with wrong IV (and thus MAC check fails). So, packets
1793 that are in queue should be encrypted when they are sent to
1794 the wire and not when they put to the queue.
1796 However, the problem is that the current system has not been
1797 designed to work that way. Instead, the packet is encrypted
1798 as soon as possible and left to the queue. The queue is then
1799 just purged into wire. There won't be any fixes for this
1800 any time soon. So, the current semantic for packet sending
1803 o If you send packet to remote host and do not force the send
1804 (the packet will be in queue) then all subsequent packets to the
1805 same remote host must also be put to the queue. Only after the
1806 queue has been purged is it safe again to force the packet
1809 o If you send all packets immediately then it safe to send
1810 any of subsequent packets through the queue, however, after
1811 the first packet is put to queue then any subsequent packets
1812 must also be put to the queue.
1814 Follow these rules and everything works fine.
1816 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added new function silc_server_remove_clients_by_server to
1819 remove all client entries from ID list when the server connection
1820 is lost. In this case it is also important to invalidate all
1821 client entires as they hold the invalid server entry. This
1822 fixes fatal bug when server has lost connection and will reconnect
1825 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Made some sanity checks to silc_server_daemonise like to check
1828 whether the requested user and group actually exists.
1830 * Added sanity check to SKE's silc_ske_responder_finish to check
1831 that the public and private key actually is valid.
1833 * Invalidate the client's nickname when receiving Replace ID
1834 packet and the Client ID is being replaced. This means that the
1835 server will query the nickname if someone needs it (client)
1838 * Sort the ID Cache in client library when the ID Cache data
1839 has changed (needs sorting).
1841 * Do not allow for SILC client to create several connections to
1842 several servers. The client does not support windows right now
1843 and generating multiple connections causes weird behaviour.
1845 Irssi-silc client does support windows and can handle several
1846 connections without problems, see: www.irssi.org and SILC plugin.
1848 * Fixed some places where client was added to the IDList. The
1849 rule of thumb is following (in order to get everything right):
1850 If the client is directly connected local client then the
1851 `connection' argument must be set and `router' argument must be
1852 NULL to silc_idlist_add_client function. If the client is not
1853 directly connected client then the `router' argument must
1854 bet set and the `connection' argument must be NULL to the
1855 silc_idlist_add_client function.
1857 * The funtion silc_server_packet_send_local_channel actually did
1858 not check whether the client was locally connected or not. It
1859 does that now. Fixed a bug related to LEAVE command.
1861 * Fixed Remove Channel User payload parsing bug in server's
1862 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1864 * The server's silc_server_save_channel_key now checks also the
1865 global ID list for the channel as it might not be in the local
1866 list. Fixed a bug related to LEAVE command.
1868 * Is this the end of the [<unknown>] buglet that has been lurking
1869 around for a long time? A little for loop fix in server's
1870 silc_server_command_whois_parse that is used by both IDENTIFY
1871 and WHOIS command. At least, this was a clear bug and a cause
1872 of one type of [<unknown>] buglet.
1874 * WHOIS and IDENTIFY commands call the function
1875 silc_server_command_[whois/identify]_check function even if
1876 we are not router server.
1878 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Added --with-gmp configuration option. If set the GMP
1881 is always compiled in the SILC source tree. If not set then
1882 it is checked whether the system has the GMP3 installed. If
1883 it has then the GMP won't be compiled (the system's headers
1884 and library is used), if it doesn't have it then the GMP is
1885 compiled in the SILC source tree.
1887 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Changed RSA private exponent generation to what PKCS #1
1890 suggests. We try to find the smallest possible d by doing
1891 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1892 not security fix but optimization.
1894 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added new config entry [Identity] to fork the server and run
1897 it as specific user and group. A patch from Bostik.
1899 * Imported Dotconf configuration library into lib/dotconf.
1900 This will be used to create the SILC configuration files later.
1901 It will appear in the distsribution after this commit.
1903 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * A big code auditing weekend happening. Auditing code for
1906 obvious mistakes, bugs and errors. Also, removing any code
1909 Removed files for being obsolete:
1911 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1912 inline in the file lib/silcutil/silcbuffer.h)
1914 o lib/silcutil/silcbufutil.c (the header has inline versions)
1916 Changed code to fix possible error conditions:
1918 o The buffer formatting routines now check that the destination
1919 buffer really has enough space to add the data. This applies for
1920 both buffer formatting and unformatting
1921 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1922 unformatting was changed to accomodate following rules:
1923 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1924 sent to the function while XXX_*STRING will not allocate or copy
1925 the data into the buffer. Instead it sets the pointer from the
1926 buffer into the pointer sent as argument (XXX_*STRING used to
1927 require that the pointer must be allocated already). This change
1928 makes this whole thing a bit more consistent and more optimized
1929 (note that the data returned in the unformatting with XXX_*STRING
1930 must not be freed now). The routines return now -1 on error.
1932 o Tried to find all code that use buffer_format and buffer_unformat
1933 and added return value checking to prevent formatting and
1934 especially unformatting errors and possible subsequent fatal
1937 o Changed ske->x and ske->KEY to mallocated pointers in
1938 lib/silcske/silcske.h. Fixed possible data and memory leak.
1940 o Added return value checking to all *_parse* functions. Fixed
1941 many memory leaks as well.
1943 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1944 so that buffer overflows would not happen. All code now also
1945 checks the return value as it can fail.
1947 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Added reconnection support to server if the normal server looses
1950 its connection to the router (for example if router is rebooted).
1951 The server performs normal reconnection strategy implemented
1952 to the server. Affected file silcd/server.c.
1954 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Added new packet type SILC_PACKET_SET_MODE that is used to
1957 distribute the information about changed modes (for clients,
1958 channels and clients channel modes) to all routers in the
1959 network. Updated the protocol specification accordingly.
1961 Added functions into silcd/packet_send.c and
1962 silcd/packet_receive.c: silc_server_send_set_mode,
1963 silc_server_set_mode.
1965 Added new files silcmode.[ch] into lib/silccore that implements
1966 the encoding and decoding of Set Mode Payload. Added new type
1967 SilcSetModePayload. Moved the definitions of different modes
1968 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1970 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Oops, a little mistake in server's connection authentication
1973 protocol. The protocol is not ended with FAILURE but with
1974 SUCCESS if the authentication is Ok. :) Affected file is
1977 * Implemented NICK_CHANGE notify handling in server in the file
1978 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1979 the local clients on the channel. After the changing nickname
1980 in router environment snhould work and the [<unknown>] nickname
1981 should appear no more.
1983 The silc_server_replace_id function that receives the Replace ID
1984 payload now sends the NICK_CHANGE notify type also in the file
1985 silcd/packet_receive.c
1987 * Changed WHOIS and IDENTIFY command to support the maximum amount
1988 of arguments defined in protocol specs (3328 arguments). This
1989 fixed a bug that caused problems when there were more than three
1992 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Added extra parameter, command identifier, to the
1995 silc_client_send_command so that explicit command identifier
1998 Changed that ID list routines uses specific command identifier
1999 when sending WHOIS/IDENTIFY requests to the server so that they
2000 can be identified when the reply comes back.
2002 Affected files lib/silcclient/command.[ch],
2003 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2005 * Added `sender' argument to silc_server_packet_send_to_channel
2006 to indicaet the sender who originally sent the packet to us
2007 that we are now re-sending. Ignored if NULL. Affected file
2008 silcd/packet_send.[ch].
2010 * Added some server statistics support in silcd/server_internal.h
2011 SilcServerStatistics structure and around the server code. Also
2012 send some nice statistics information when client is connecting
2015 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed channel ID decoding in server's JOIN command reply in
2018 silcd/command_reply.c
2020 * Fixed braodcasting of replace ID payload to not to send it if
2021 we are standalone server in silcd/packet_receive.c.
2023 * Fixed all channel message sending routines to not to send
2024 packets to clients that has router set, since they are routed
2025 separately in the same function earlier. Affects file
2026 silcd/packet_send.c and all channel packet sending functions.
2028 * In USERS reply, res_argv[i] are not allocated, the table
2029 is allocated. Thus changed that free the table, not its
2032 * In server's whois_check and identify_check if the client is
2033 locally connected do not send any WHOIS commands - they are not
2036 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed some minor bugs in client when sending WHOIS command. The
2039 arguments was in wrong order.
2041 * Removed statis function add_to_channel from server in
2042 silcd/command.c that was previously used with the joining but
2045 * Tested USERS command in router environment successfully with two
2046 routers, two servers and two clients.
2048 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Reorganized the USERS command and command reply in client library
2051 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2052 When the command is given by user we register a pending command
2053 callback that will reprocess the command after the reply has been
2054 received from the server. When reprocessing the packet we then
2055 display the information. Thus, the USERS information is displayed
2056 now in the command callback instead of in the command reply
2057 callback. The processing of the command is same as previously
2058 when server has sent the command reply in the JOINing process.
2060 * Added to USERS command in silcd/command_reply.c to join the client,
2061 we didn't use to know about, to the channel after we've created
2062 a client entry for it. Also, for clienet we did know already still
2063 check whether it is on the channel or not and add it if not.
2065 * Removed silc_server_command_join_notify as the function and its
2068 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Changed the client's pending command handling to the same as the
2071 server's pending command handling. It is also now possible to
2072 execute command reply functions from other command reply
2073 function as the function callbacks for commands and command
2074 replies are one and same. The pending commands are not static
2075 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2076 in client connection context. Thus, pending commands are server
2077 connection specific as it is convenient.
2079 Changed the function silc_client_command_pending and
2080 silc_client_command_pending_del and added new function
2081 silc_client_command_pending_check. Removed the
2082 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2085 * Added cmd_ident, current command identifier, to the client
2086 connection context in lib/silcclient/client.h to keep track on
2087 command identifiers used in command sending. Client's command reply
2088 function handling now supports the mandatory command identifiers.
2090 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2091 funtions in client to fully support pending command callbacks.
2093 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2094 as one of the arguments to the application in the command reply
2097 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2098 before first releasing SILC but came back. Now it is removed again
2099 and should come back nomore. The FORWARDED flag was used only
2100 by the JOINing procedure by forwarding the command packet to router.
2101 Now, the JOINing procedure has been changed to more generic (due
2102 to various router environment issues) and FORWARDED is not needed
2103 anymore for anything. The protocol specification is yet to be
2106 Now, removed silc_server_packet_forward from server and the flag
2107 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2109 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Renamed NAMES command to USERS command. The NAMES was named that
2112 due to historical reasons. Now it is renamed. Also, rewrote
2113 parts of the USERS command. The nickname list is not sent anymore
2114 by the server. Only Client ID and mode lists are sent in the USERS
2115 command. Changed this also to the protocol specification.
2117 The client now resolves the names and stuff after it receives
2118 the USERS list from the server when joining to the channel.
2120 * WHOIS and IDENTIFY commands has been changed to support multiple
2121 Client ID's per command. One can now search for multiple users
2122 in the network by sending only one WHOIS or IDENTIFY command.
2123 Changed the code and the protocol specifications.
2125 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2126 uses silc_server_command_whois_parse to parse the request. */
2128 * If normal server, do not parse the WHOIS and IDENTIFY requests
2129 before sending it to the router. Saves some time.
2131 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Fixed JOIN command on client library. Wrong number of arguments
2134 used to crash the client.
2136 * Added silc_server_channel_has_global function to check whether
2137 channel has global users or not.
2139 * Added silc_server_channel_has_local function to check whether channel
2140 has locally connected clients on the channel.
2142 * The silc_server_remove_from_one_channel now checks whether the
2143 channel has global users or not after given client was removed from
2144 the channel. It also checks whether the channel has local clients
2145 on the channel anymore. If it does not have then the channel entry
2146 is removed as it is not needed anymore.
2148 * The silc_server_notify now checks on JOIN notify whether the joining
2149 client is one of locally connected or global. If it is global then
2150 the channel has now global users on the channel and that is marked
2151 to the channel entry. Also, it now saves the global client to
2152 global list who is joining and JOINs it to the channel. This is
2153 for normal server, that is.
2155 Changed silc_server_send_notify_on_channel,
2156 silc_server_packet_relay_to_channel and
2157 silc_server_packet_send_to_channel check if we are normal server
2158 and client has router set (ie. global client) do not send the
2159 message to that client, as it is already routed to our router.
2161 * Implemented LEAVE notify type handling in silc_server_notify
2164 * Tested LEAVE command in router environment successfully. Tested
2165 with two routers, two servers and two clients.
2169 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2171 * Implemented SIGNOFF notify type handling in silc_server_notify
2174 * silc_server_remove_id now removes the client entry from all channels
2175 it has joined and thusly sends SIGNOFF notify type.
2177 * Rewrote the NAMES list generation in server by removing two excess
2178 loops. The lists are created now inside one loop.
2180 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * silc_server_remove_channel_user checks now also global list
2183 for channel and client.
2185 * silc_server_new_channel_user checks now both local and global
2186 list for channel and client. Fixed a bug in client id decoding.
2187 Used to decode wrong buffer.
2189 * silc_server_channel_message checks now both local and global
2190 list for channel entry.
2192 * Tested channel joining (hence JOIN) in router environment
2193 successfully. Tested with two routers, two servers and two
2196 * Tested channel message sending in router environment successfully.
2198 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Added silc_server_save_channel_key into server.[ch] to save the
2201 received channel key in Channel Key payload processing. It is
2202 also used in JOIN command reply handling.
2204 Equivalent function silc_client_save_channel_key added into
2205 client.[ch] into client library.
2207 * Changed JOIN command reply to send information whether the channel
2208 was created or not (is existing already) and the channel key
2209 payload. Changed protocol specs accordingly.
2211 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2212 the request was sent by ID and not by nickname. Crashed on
2215 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2218 now correctly save the received data.
2220 * silc_server_free_sock_user_data now notifies routers in the
2221 network about entities leaving the network.
2223 At the same time implemented functions silc_server_remove_id
2224 and silc_server_send_remove_id to receive and send REMOVE_ID
2225 packets. The packet is used to notify routers in the network
2226 about leaving entities. The ID removed will become invalid in
2229 * Added function silc_idlist_del_server into server. Removes and
2230 free's server entry from ID list.
2232 * silc_server_private_message function now checks, if we are router,
2233 that the destination ID really is valid ID, naturally.
2235 * In router when NEW_ID packet is received (for new client) the
2236 hash of the Client ID is saved in the ID Cache but the
2237 client->nickname is set to NULL, instead of putting the hash
2240 IDENTIFY command now also checks that client->nickname must be
2241 valid. If it is not if will request the data from the server who
2242 owns the client. Added new function
2243 silc_server_command_identify_check.
2245 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2246 to set the command to already allocated Command Payload.
2248 * Tested private message sending in router environment with two
2249 routers, two servers and two clients. Fixed minor bugs and now
2252 * Fixed segfault from client's NAMES command. Used to crash if
2255 * Forwarded packets must not be routed even if it is not destined
2256 to the receiver. Changed server code comply with this.
2258 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Added `require_reverse_mapping' boolean value to ServerParams
2261 structure. If TRUE (not default) the server will require that
2262 the connecting host has fully qualified domain name.
2264 If the reverse mapping is not required and hostname could not be
2265 found the IP address is used as hostname.
2267 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Implemented version string checking to both client and server.
2270 The check is incomplete currently due to the abnormal version
2271 strings used in development version of SILC.
2273 * Changed all command functions in server to use the new
2276 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Changed char *data to unsigned char *data in ID Cache system to
2279 support binary data as ID Cache data. Changed code to support
2280 binary data in lib/silccore/idcache.c.
2282 * Renamed silc_server_packet_relay_command_reply to
2283 silc_server_command_reply as it is normal packet receiving
2284 function. Rewrote the function to accept command replys for
2285 servers and not only for clients.
2287 * Mark remote router always as registered server if we are connecting
2288 to it. Otherwise, commands sent by the router to us are ignored.
2290 * All ID List find routines now returns the ID Cache Entry pointer
2291 as well if requested.
2293 * WHOIS command works now in router environment, tested with two
2294 routers, two servers and two clients.
2296 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2297 in router environment (as it is almost equivalent to WHOIS) but
2298 hasn't been tested thoroughly. Added new functions:
2300 silc_server_command_identify_parse
2301 silc_server_command_identify_send_reply
2302 silc_server_command_identify_from_client
2303 silc_server_command_identify_from_server
2305 * Disabled route cache adding because adding two different ID's with
2306 same IP replaces the old cache entry thus giving wrong route.
2307 The entry->router->connection is always the fastest route anyway
2308 so route cache may not be needed. Of course, new routes maybe
2309 established after receiving the ID when the entry->router->connection
2310 might not be anymore the most optimal.
2312 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Add route cache for received ID for fast routing.
2316 * Added silc_server_packet_route to route received packet on router
2317 that is not destined to us.
2319 * Renamed silc_server_get_route to silc_server_route_get.
2321 * Added id_string and id_string_len fields into SilcServer to
2322 include encoded ServerID for fast comparing without excess
2323 encoding of the ID's.
2325 * Cleaned up WHOIS command on server side. Added following static
2328 silc_server_command_whois_parse
2329 silc_server_command_whois_check
2330 silc_server_command_whois_send_reply
2331 silc_server_command_whois_from_client
2332 silc_server_command_whois_from_server
2334 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2335 arguments in command replies. All command functions should be
2336 updated to use this macro.
2338 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Minor typo fixes on command reply handling on server.
2342 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added silc_server_command_add_to_channel internal routine to add
2345 the client to the channel after router has created the channel and
2346 sent command reply to the server.
2348 * Added generic silc_server_send_command to send any command from
2351 * Use static buffer with ID rendering instead of duplicating data.
2353 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Fixed a channel user mode bug when joining to a channel server gave
2356 everybody channel founder rights, oops.
2358 * We mark ourselves as the router of the incoming server connection
2359 if we are router ourselves. This way we can check in some packet
2360 sending functions whether it is locally connected server. For
2361 incoming router connections we put NULL.
2363 * For router sending packets locally means now always sending the
2364 packet cell wide; to local clients and local servers. For normal
2365 server sending packet locally means sending it to only local
2368 * Fixed the JOIN command to really work in router environment. If the
2369 channel is created it is always created by the router. Router is
2370 also responsible of making the initial joining to the channel,
2371 sending JOIN notify to the sending server and distributing
2372 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2373 does not exist server doesn't do anything else but forward the
2374 command to the router which performs everything.
2376 * Added silc_server_send_channel_key function to send the Channel Key
2379 * Added silc_server_create_channel_key to create new channel key. The
2380 channel key is now re-generated everytime someone joins or leaves
2381 a channel, as protocol dictates. Note: channel->key_len is the
2384 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2387 packet_receive.[ch] to separate packet sending and receiving
2388 routines. The server.[ch] now includes everything else including
2389 actual packet processing (writing and reading data) and other
2392 Renamed silc_server_private_message_send_internal to
2393 silc_server_send_private_message. The routine is still though
2394 used only to relay private messages as server does not send
2395 private messages itself.
2397 Renamed silc_server_new_channel to silc_server_create_new_channel
2398 and added new function sicl_server_new_channel that handles the
2399 incoming New Channel packet. Added also new sending function
2400 silc_server_send_new_channel to send New Channel Payload.
2402 * Added new function silc_server_notify to process incoming notify
2403 packet to the server/router. Server may then relay the notify
2404 to clients if needed.
2406 * Added new function silc_server_new_channel_user to process incoming
2407 New Channel User packet. Router will redistribute the packet and
2408 send JOIN notify to its local clients and locally connected servers
2409 if needed. Normal server will send JOIN notify to its local client
2410 on same channel when received this packet. Added also corresponding
2411 sending function silc_server_send_new_channel_user to sent the
2414 * Added boolean route argument to send_notif_to_channel and
2415 packet_send_to_channel functions to attempt to route the packet
2416 if it is TRUE and send only locally if it is FALSE.
2418 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * silc_server_replace_id now broadcasts the received replace ID
2421 packet if it is not broadcast packet already. The router must
2422 broadcast to inform other routers about changed ID.
2424 * Added backpointer to server's router into SilcServer context in
2425 silcd/server_internal.h.
2427 * Fixed silc_server_packet_broadcast to send correct broadcast
2430 * The channel key is now distributed to the local client as soon
2431 as it is received from the router (in router environment) so that
2432 no other packet may be sent for the channel until client has
2435 * silc_server_remove_channel_user now broadcasts the received
2436 Remove Channel User packet if it is not broadcast packet already.
2437 The router must broadcast to inform other routers about removed
2440 * Added users field into SilcPacketContext that is a reference count
2441 of the context. One can increase the reference count by calling
2442 silc_packet_context_dup which is now changed to just increase the
2443 reference count instead of duplicating the data. The reference
2444 count is decresed by calling silc_packet_context_free that will
2445 free the data after the reference count hits zero.
2447 For now on the packet context and everything allocated into it
2448 (including the raw packet from network) must be freed by calling
2449 the new silc_packet_context_free function. Added also new function
2450 silc_packet_context_alloc that must be used now to allocate the
2451 context. This also means that if a routine is asynchronous from
2452 silc_[client/server]_packet_parse_type the packet context must
2453 be duplicated by calling silc_packet_context_dup. Otherwise it
2454 gets free'd after silc_[client/server]_packet_parse_type returns.
2455 Also, one must remember that if packet is duplicated then its
2456 reference count must be decresed by calling the free function as
2457 many times as it was duplicated.
2459 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2460 from both client and server.
2462 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Made joining to a channel working in router environment.
2466 * Cleaned up JOIN command on server side and create function
2467 silc_server_command_join_channel internal routine to make the
2470 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Changed silc_command_pending list to SilcDList. Also, added
2473 `ident' field to SilcServerCommandPending structure to identify
2474 the reply and to call correct callback.
2476 Added silc_server_command_pending_check function to replace the
2477 corresnponding macro. The silc_command_pending list is not
2480 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2481 to set identifier to previously allocated Command Payload. It
2482 is used to set identifier for command when resending Command
2485 * Added silc_command_payload_encode_payload to encode Command
2486 Payload buffer from SilcCommandPayload structure.
2488 * Added silc_argument_payload_encode_payload to encode Argument
2489 payload buffer from SilcArgumentPayload structure.
2491 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Changed WHOIS command to support router connection on server side.
2494 The whois request is always sent to router unless the server is
2495 standalone server. After server has received the reply from the
2496 router will it send the reply to the client.
2498 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2499 broadcast received broadcast packet. The function is used only
2500 by router. The broadcast packet is always sent to the router's
2503 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2504 render given ID to printable string, for log files for example.
2506 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Made basic router to router connections working. At least they
2509 can now connect to each other but nothing really works the way
2510 they are supposed - yet.
2512 * Added new initiator token to RouterConnection configuration
2513 file in silcd/serverconfig.[ch]. It is used to tell whether we
2514 are the initiator to the remote router or whether we'll expect
2515 the other end to connect.
2517 * Moved registering of listener task to silc_server_init, hence
2518 the server starts listenning as soon as it is run, even if it
2519 does not have connections to other routers. Let's see how well
2522 * Changed default connection retry timeouts for more suitable in
2525 * Removed cipher and such arguments from silc_idlist_add_client
2526 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2527 Added new function silc_idlist_add_data to add the keys and stuff
2530 * Added SilcIDListData structure and added it to SilcClientEntry
2531 and SilcServerEntry as their first field in the structure. This
2532 way we can explicitly cast the ID entries to the SilcIDListData
2533 structure and get common data for the entries. In past, we had
2534 to first check what type of connection it is and then cast it to
2535 correct ID entry type. Now, we can directly cast the opaque
2536 pointer to the SilcIDListData (no matter what ID entry it actually
2537 is) and get the data needed.
2539 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2541 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2542 in some circumstances even if threre were timeout tasks, though not
2543 IO tasks, but tasks anyway. Now fixed.
2545 * Defined SilcServerConnection structure to hold connection specific
2546 stuff about directly connected servers and routers. The definition
2547 is currently in silcd/server_internal.h. I thought about having
2548 a bit more important role fro this struct but for now it is used
2549 only when connecting to other server (or router actually).
2551 * Added connecting retry support in server when connecting to
2552 router(s). The retry feature implement exponential backoff
2553 algorithm. Also, added SilcServerParams structure to hold default
2554 parameters for server. For now, it include these retry settings
2555 and are hard coded. After server is moded to be as Silc Server
2556 Library this structure will be more important.
2558 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Changed client librarys channel->clients table to SilcList and
2561 changed code accordingly.
2563 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Changed client's channel table to SilcList and changed code
2566 accordingly. Also changed SilcChannelClientEntry to include back-
2567 pointer to the channel so that client entry can use that structure
2568 as list as well and we have fast cross-reference to the channel.
2569 This change dramatically decreased the complexity of channel
2570 handling with client entry and vice versa (removed one extra
2571 loop when searching for channel entry from many functions).
2573 * Changed server->sim from table to SilcDList and changed code
2576 * NAMES command can now be used from user interface. It will show
2577 the user list on the channel, neatly.
2579 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2580 Code now saves realname of the user if it becomes available.
2582 * Renamed configure.in to configure.in.pre and made ./prepare
2583 script to automatically add correct version string to
2584 configure.in which it creates from configure.in.pre.
2586 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * NAMES command reply now shows users mode with the nickname when
2591 * Moved silc_client_ch[u]mode[_char] functions from
2592 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2593 place sucks, they are utility functions and should be in some
2596 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2598 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2601 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added TRQ (efficient deque and list library) into lib/trq. This is
2606 a very good list library that is currently used in the SILC. Defined
2607 SilcList API over the library because I didn't like the API very
2608 much. See lib/trq/silclist.h for the API and examples of how to
2609 use the API. Fixed various places in the code to use the new
2610 SilcList API. The SilcList is meant for lists that has a structure
2611 already defined as a list. It is not suitable to add just some
2612 context to the list (in TRQ, the context is the list actually).
2614 So, I defined SilcDList that can be used for the purpose where
2615 predefined list structure does not exit. This can be used as
2616 such list. Now some context just can be added to the SilcDList.
2617 Currently this list is not used in the SILC just yet, though there
2618 are a lot places where this can replace dynamically allocated
2619 tables and I will fix these places, later, to use SilcDList.
2620 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2621 and use TRQ internally).
2623 Also fixed some annoying warning messages that the original TRQ
2624 code generated. Also minor changes to TRQ's Makefile.in.
2626 * Added support for querying by Client ID to both WHOIS and
2627 IDENTIFY commands into server, as required by the protocol.
2629 * Removed method function pointers from SilcBuffer structure. They
2630 weren't used to anything and just increased the context size for
2631 no good reason. This change also made silc_buffer_alloc and
2632 silc_buffer_free functions inline functions.
2634 * Disabled command flooding detection support until it's fixed so
2635 that it accepts commands in but does not execute them more than once
2638 * Added silc_net_localhost(), to return local hostname, into
2639 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2640 that must be initialized before calling silc_client_init.
2642 * Added new function: silc_server_send_notify_on_channels to send
2643 notify messages to all channels client has joined. It is assured
2644 that the message is sent only once per client.
2646 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2647 lib/silcutil/silcutil.[ch] as silc_format function. The new
2648 function is generic and is used by server as well, not only by
2649 the logging routines.
2651 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2652 the provided version string was not acceptable. Added new function:
2653 silc_ske_check_version into lib/silcske/silcske.h. The function
2654 must be implemented by the application (client or server) and it
2655 does not reside in the SKE library. The function checks the version
2656 string remote end sent.
2658 * Added back pointers (to opaque context and to SilcSocketConnection)
2659 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2661 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2662 duplicate packet context structure.
2664 * Changed `notify' client operation to send same arguments as client
2665 receives from server except for ID's. ID's are mapped to correct
2666 ID entry and that is returned. Also, if channel entry is not sent
2667 by server but the notify is for channel the channel entry is sent
2668 to application (otherwise application doesn't know that it is for
2669 channel (library gets it from packet's Destination ID)).
2671 * Added silc_client_remove_from_channels into client library to
2672 remove a client from all channels it has joined to. Used when
2673 received SIGNOFF notify from server. Added also new function
2674 silc_client_replace_from_channels to replace old ID entry with
2675 new ID entry on all channels. Used when received NICK_CHANGE
2678 * Fixed ID Cache list handling in silc_idlist_get_client in
2679 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2680 to get (or query) client by ID.
2682 * Updated TODO list.
2684 * Added connection authentication status message defined by the
2685 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2686 support for these into the code in client and server side.
2688 * Added generic function silc_client_send_command to send any command
2689 with variable argument list. Application should use this function
2690 to send commands if the command functions provided by the library
2691 does not suite for the application's user interface needs.
2693 * Added new `failure' client operation. Application is notified about
2694 received failure packet if client is executing a protocol. In this
2695 case the protocol's execution has failed.
2697 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2698 is required by the protocol.
2700 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2701 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2704 * Added status flag to SilcSKE object to indicate realtime status
2705 of the SKE protocol.
2707 * Application receives now exactly same command reply arguments as
2708 the library receives from server. However, if ID is received the
2709 corresponding ID entry is returned to the application (eg. Client
2710 ID is mapped to correct SilcClientEntry entry and that is returned).
2711 Changed command_reply client operation due to this change.
2713 * Changed all ID's in commands and in command replys as ID Payloads.
2714 Change affected both client and server side codes.
2716 All ID's sent in SILC network (with execption of ID's in SILC
2717 Packet header) are sent in ID Payload to support variable length
2720 * Server now notifies nick changes and notifies all clients on
2721 the channels about the new nickname (about the new Client ID,
2724 * Implemented CMODE command to change channel modes. Supports all
2725 channel modes defined by the protocol specs except ban and invite
2726 lists. (Also, private channel key mode is supported but support for
2727 setting private channel key in client is missing, thus, this mode
2728 has no effect on client side (except that server requires that the
2729 client uses private channel key and normal channel traffic does not
2732 Also, invite mode works per se, but INVITE command does not work
2733 yet correctly, so you can set channel as invite only channel but
2734 inviting clients to the channel does not work (it is yet to be
2735 thought what's the best way to do it).
2737 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2738 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2739 Implemented CUMODE command to change user's mode on the channel.
2740 Supports all modes defined by the protocol specs.
2742 * Added NAMES command reply to return users modes on the channel.
2744 * Removed unnecessary and slow ciphers from lib/silccrypt.
2746 * Set SO_KEEPALIVE option to connection sockets by default.
2748 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2750 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2751 redefined the Notify Payload into protocol specs.
2753 * Added silc_id_payload_parse_id to get ID directly from raw
2756 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2759 accept searching by Client ID as well.
2761 * Added support for LEAVE and SIGNOFF notify types in client library.
2763 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2764 to parse ID Payload from raw data.
2766 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Added flags parameter into silc_ske_assemble_security_properties
2769 function in lib/silcske/silcske.[ch].
2771 * Changed notify client operation to fit better for notify messages
2772 sent by server. The notify payload received from server is now
2773 passed to the application (after parsing it to SilcNotifyPayload).
2774 It is application's responsibility to retrieve the arguments
2775 from the payload and show the message the way it wants. The message
2776 sent by server is implementation specific.
2778 * Changed public keys to comply with the protocol specification.
2779 Old public keys are not supported anymore and are not compatible.
2781 * Removed nickname from Channel Payload as the latest draft removed
2782 it. The client must resolve the nickname from the NAMES command
2783 reply received when it joined the channel.
2785 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2787 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Fixed some errors in protocol specification drafts.
2791 * Created lib/silccore/silcnotify.c to implement Notify Payload
2792 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2793 generic payloads described by protocol specifications. The file
2794 includes implementations for ID Payload and Argument Payload.
2796 * Changed Command Payload implementation to use the new Argument
2797 Payload. Changed command_xxxx_payload to command_payload_xxxx
2798 to comply with SILC coding conventions.
2800 * Added suppport for Argument Payload handling in Notify Payload
2801 implementation as protocol requires it. Added the new support
2802 into server and client lib as well.
2804 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Added support for multiple nicknames on same channel. [n] is
2807 added locally to the nickname if there are more than one same
2808 nicknames on the channel.
2810 * Server now sends all nicknames that matched WHOIS request.
2811 Client also shows the list received from server.
2813 * Added TOPIC command to client side. User can now set and show
2814 current topic on channel.
2816 * Added MOTD command to client and server. Also, server sends the
2817 motd when client connects to the server.
2819 * Changed version strings to comply ISO 8601.
2821 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Fixed protocol error handling in client library. It should now
2824 cope even if the SKE fails for some reason.
2826 * Made new protocol specification drafts for submitting to IETF.
2828 * Implemented TOPIC command to server in silcd/command.c.
2830 * Added two new notify types into lib/silccore/silcnotify.h:
2831 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2832 notify nickname change and topic setting/change on a channel.
2834 * API change of command_reply operation in client library. The
2835 application gets now the status type received from server as well.
2837 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2841 * Cras fixed and optimized the packet handling even further and
2842 it should work now. Minor change to the prototype of function
2843 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2845 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Added new function into lib/silcutil/silcschedule.[ch]:
2848 silc_schedule_with_fd to select() a specified fd. The function
2849 returns after timeout expires or data arrives or goes. The
2850 function is used by packet routines to wait that all data is
2851 received from network.
2853 * Fixed data reading from network in lib/silccore/silcpacket.c.
2854 The code now assures that all data is read from the fd and then
2855 continues packet processing. This was a bug fix since the code
2856 used to drop some data in some circumstances.
2858 * Added new function into lib/silcclient/client.[ch]:
2859 silc_client_start_key_exchange to start key exchange after
2860 connection has been established to server. The code internally
2861 now uses this funtion but its main purpose was to provide it
2862 for applications that perform their own connecting. After
2863 application has created a connection it merely calls this
2864 function to start the key exchange between client and server.
2865 The library takes care of everything else after that.
2867 Updated also lib/silcclient/README to explain the usage of
2870 * Do not send to application information that connection has
2871 been established. Application gets notified it by connect
2874 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Applied cras's patch to add silc_schedule_one function. The
2877 function runs scheduler once and returns.
2879 * Fixed the scheduler after cras messed it up. The timeout
2880 handling works now as it's supposed to work.
2882 * Added into lib/silccore/ silcnotify.h to include notify
2883 message types support. Changed silc_server_send_notify*
2884 functions, in server.[ch], to support those new notify types.
2885 Added the support for the notify types into client library,
2886 as well. Added new notify client operation into ops.h in
2889 * Changed silc_server_packet_send_to_channel to send normal
2890 packets instead of just channel message packets. The function
2891 is now used to send the notify packets to channels. It is not
2892 used to send channel message packets anymore, as server never
2895 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2896 va_arg()s as it seems to require it nowadays. I guess, if SILC
2897 is compiled with older va_arg() the new code should work anyway.
2899 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Splitted core library. Core library (lib/silccore) includes
2902 now only SILC protocol specific core (and common) components.
2903 Created new utility library (lib/silcutil) that includes more
2904 generic purpose stuff. The stuff for util library was taken
2905 from the old core library. This was minor and easy split.
2907 * Created SILC Client Library (lib/silcclient) that includes
2908 implementation of the SILC client without user interface. This
2909 was major move from silc/ directory. The code has been changed
2910 so that it is transparent towards the user interface. The
2911 silc/ directory includes now the same user interface as before
2912 and it uses the new client library. Read lib/silcclient/README.
2913 Basicly, the client library performs everything else related
2914 to SILC except user interface handling. Also, configuration
2915 files are considered to be part of user interface and library
2916 does not handle them.
2918 This change also changed a lot of structures, function naming etc.
2919 Most important change was that SilcClientWindow object was
2920 renamed to SilcClientConnection in the client library. Created
2921 also new file lib/silcclient/ops.h. Also added new files
2922 silc/local_command.[ch] and silc/client_ops.[ch].
2924 All these changes were made to make it easier for user interface
2925 designers to create what ever user interface for the SILC client
2928 It is also expected that the server will be moved to lib
2929 directory as well and SILC Server Library will be created;
2930 sometimes in the future.
2932 * Removed Local commands from lib/silccore/silccommand.h as
2933 they are application specific and new client library does not
2934 handle any of those anymore.
2936 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2937 old client implementation in silc/.
2939 * Added support for callback functions in SILC_LOG_* macros.
2940 Application can now set its own callbacks that will be called
2941 instead of using the default functions that will always print
2942 the debug messages to stderr (or stdout). Also, debugging can
2943 now be disabled by setting silc_debug to FALSE and re-enabled by
2944 setting it to TRUE. Note, that logging will still work even
2945 if debugging is disabled.
2947 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2948 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2949 silc_log_reset_debug_callbacks.
2951 * To enable debugging in silc client one must give now -d
2952 option on command line.
2954 * Changed silc_schedule_init to automatically allocate task queues
2955 if they are not allocated before calling it.
2957 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added GMP 3.1 into math library.
2961 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2964 a channel in SILC network. The packet is used by servers and
2965 routers to notify other routers that user has left a channel.
2966 This little feature was missing until now. Added the feature
2967 to protocol specification as well.
2969 Added functions: silc_server_send_remove_channel_user and
2970 silc_server_remove_channel_user into server.[ch].
2972 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2973 lib/silccore/silcpacket.h. However, they are not implemented
2976 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Fixed joining to a channel and sending channel messages
2979 between server and router. The channel message sending should
2980 now work inside a cell.
2982 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Fixed the private message sending between server and router.
2985 The private message sending should now work inside a cell.
2987 * Added silc_server_replace_id into server.[ch] to replace
2988 existing ID in the SILC network.
2990 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2991 and silc_idlist_replace_server_id into idlist.[ch] in server.
2993 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Fixed the server to server connections. Server can again now
2996 connect to router. Router to router connections probably does
2999 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Added dynamic protocol registering support. Now protocols can
3002 registered and unregistered on the fly. Patch by cras.
3004 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Added lib/contrib directory to hold routines that some platforms
3007 don't have but are needed by SILC.
3009 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3010 into lin/contrib to provide getopt() and getopt_long() for
3011 those who don't have it.
3013 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added AWAY command to client. When away message is set and
3016 client receives a private message packet the client automatically
3017 replies to the sender with the away message.
3019 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3020 bug seemed to be the cause of recent problems when compiling
3023 * Added version detection support to SKE protocol specification
3024 and added the new changes to the SKE implementation as well.
3025 There were other minor changes in the SKE protocol as well.
3027 Many changes in lib/silcske/silcske.[ch] and in
3028 lib/silcske/payload.[ch].
3030 * Added ^U functionality, clear input line. Patch from cras.
3032 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Mainly small bugfixes on core library. Fixed some debugging
3035 logging and buffer overflow in silclog.c.
3037 * Updated config.sub and config.guess on the distribution tree.
3039 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added command lagging support in server. Client may execute
3042 commands now only once in two seconds.
3044 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Optimized packet reception. MAC computation and checking is now
3047 also more optimized. A lot previously duplicated code is now
3048 used as generic by both client and server.
3050 * Fixed key pair generation in clientutil.c
3052 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Added into lib/silccore/silcbufutil.[ch] new function;
3055 silc_buffer_realloc.
3057 * Moved generic packet sending/encryption functions to
3058 lib/silccore/silcpacket.[ch] from client and server. Some
3059 rewriting of the functions.
3061 * Moved all generic packet reception/decryption functions to
3062 lib/silccore/silcpacket.[ch] from client and server. The
3063 packet processing is now much cleaner in both client and server.
3064 These were major changes in both client and server.
3066 * Created many common functions in server to do packet sending.
3067 Previously code were duplicated a lot, this has been removed
3070 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Rewrote major parts of the ID cache system. Don't know
3073 whether it is better now or not but at least the API is more
3076 * Major rewrite on ID cache stuff on client because of the ID
3077 cache API changes. Added idlist.c to client.
3079 * Also major rewrite on ID cache stuff on server as well.
3080 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3081 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3082 in hand, instead they are all put into the ID cache system now.
3083 All server_idlist_* routines uses ID cache now instead of
3084 traversing its own lists (those lists does not exist anymore).
3085 SilcIDList though still exists. Also, SilcXXXEntry's are
3088 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Finally made the SKE implementation compliant to the protocol
3091 specification. All mp integers are now binary encoded as
3092 opposed being HEX encoded.
3094 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3097 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3098 functions: silc_[encode/decode]_pem. Also added function
3099 silc_encode_pem_file to PEM encode with newlines ('\n') for
3102 * SILC public keys are now encoded either PEM or binary. Same
3103 option is for private keys as well. By default private keys
3104 are binary encoded and public keys PEM encoded. Silly HEX
3105 encoding were removed.
3107 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3108 function to create fingerprints.
3110 * Fixed a bug in SHA1; does not change the original data anymore.
3112 * Partly implemented INFO command on client and server side.
3113 Fixed CLEAR command. Changes to SERVER command; show current
3114 server(s) when giving command without arguments. Added
3115 VERSION command to client.
3117 * Added check to server that unregistered connections cannot
3118 execute commands (unless it is specificly allowed).
3120 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Fixed screen refresh.
3124 * Fixed channel joining bug from client. On some circumstances
3125 client tried to join to a channel it had already joined.
3127 * Added public key verification process into client's protocol.c.
3128 The client now verifies the public key from user and saves
3129 it into ~./silc/serverkeys/ directory.
3131 Added into: clientutil.[ch]: silc_client_verify_server_key.
3133 * Changed SKE protocol's silc_ske_initiator_finish function
3134 to accept callback function that verifies the received public
3135 key. Removed old silc_ske_verify_public_key function.
3137 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3140 silc_pkcs_private_key[_data]_set.
3142 * Made the password and public authentication more cleaner in
3143 server's protocol.c.
3145 * Removed historic and obsolete protocol `channel_auth' from
3146 both client and server.
3148 * Removed wrong way of sending command status messages from
3149 server to client in server's command.c. The old way violated
3150 protocol specification.
3152 Changes to silccore/silccommand.[ch]: removed
3153 silc_command_encode_status_payload -> not needed anymore,
3154 changed silc_command_encode_payload_va to accept extra
3155 argument on variable argument list. The argument type must
3156 now be provided to the function. Also, added new function:
3157 silc_command_encode_reply_payload_va which is same as
3158 normal command_encode_payload_va except command status type
3159 is provided as extra argument.
3161 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Added ~./silc directory handling. The directory includes the
3164 public and private keys for the client.
3166 Added silc_client_check_silc_dir, silc_client_create_identifier
3167 and silc_client_load_keys.
3169 * Implemented SILC protocol compliant public key. Added public
3170 and private key saving to and loading from files.
3172 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3173 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3174 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3175 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3176 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3178 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3179 silc_pkcs_load_[public/private]_key.
3181 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Added silc_server_get_route (route.[ch]) to get connection
3184 data for the fastest route for given ID.
3186 * Implemented INVITE command on client and server. The command
3187 were re-defined in the SILC Protocol Specification and the
3188 implementation now complies with the specification.
3190 * Implemented PING command on client and server.
3192 * Implemented NAMES command on client and server. The server side
3193 supports currently only normal server not router server yet.
3194 Some changes to NAMES definition in SILC protocol specification.
3196 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Implemented LEAVE command on client and server.
3200 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3201 again. This change was made to the protocol as well. Server
3202 should not violate the protocol specification anymore.
3204 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3207 was tested. SOCKS4 was not but should work anyway.
