3 * Ok, rewrote the logic of the re-key and now it seems to work.
4 I tested it on high traffic with frequent re-keys without
5 problems. Added hmac_receive (and renamed hmac to hmac_send)
6 in SilcClientConnection in lib/silcclient/client.h and
7 in SilcIDListData in silcd/idlist.h. Also, removed the
8 SilcPacketParserContext's cipher and hmac fields as they are
9 not needed anymore and actually caused some problems when
10 the ciphers and hmac's changed underneath the packet parser.
12 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
14 * If re-key protocol is active then process the incoming packets
15 synchronously since we must assure that icoming packets encrypted
16 with the old key is processed before the new keys is set to
17 use. This is true other packets than for REKEY packets.
18 Affected file silcd/server.c. The same was done to client library
19 as well, affected file lib/silcclient/client.c.
21 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
23 * Fixed bug in client and server to accept the force send if
24 the packet is send from silc_[server/client]_packet_process
25 function. Otherwise the packets are never delivered, oops.
27 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Disable force sending of packets when REKEY protocol is active.
30 We must assure that no packet is sent directly when rekey is
31 performed. All packets must be sent through packet queue.
32 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
33 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
34 function is silc_[server/client]_packet_send_real to check
37 * Replaced the SIM paths from example config files to
38 /usr/local/modules. Also, make install creates now
39 /usr/local/silc/logs directory to hold all the SILC server
42 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Made the configure.in.pre work on Solaris. Patch by salo.
46 * Made all ciphers compatible with non-x86 machines. Defined
47 CBC mode macros into lib/silccrypt/ciphers_def.h.
49 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Fixed the make install.
53 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * When MAC computation fails the silc_packet_decrypt returned 0
56 even though it was supposed to return -1. Fixed this. The
57 affected file is lib/silccore/silcpacket.c.
59 * Do not replace the config files in /etc/silc (in make install)
60 if they already exist. Affected file ./Makefile.am.
62 * Do not send re-key packets immediately but through packet queue.
63 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
65 * Changed silc_net_check_host_by_sock to return FALSE if the
66 IP/DNS could not be resolved. Though, it returns the IP address
67 now even if it could not resolve it (but returns also FALSE).
68 Affected file lib/silcutil/silcnet.[ch].
70 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Added silc_pkcs_decode_identifier to decode the public key's
73 identifier. Affected file lib/silccrypt/silpkcs.[ch].
74 Added also silc_pkcs_free_identifier. Added also new context
75 SilcPublicKeyIdentifier.
77 * Added -S option to the silc client. It is used to dump the
78 contents of the specified public key file.
80 * Changed the PKCS api to return the public key length when
81 setting the public key.
83 * Fixed a fatal bug in the public and private key file loading.
84 Affected file lib/silccrypt/silcpkcs.c.
86 * Execute the packet parsing for client with zero (0) timeout
87 if the protocol is active. Affected file silcd/server.c.
89 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
91 * Made the key generation options to the silcd program. Added
92 -C option, equivalent to client's option.
94 * Added new [ServerKeys] config section to the server. It
95 configures the server's public and private key.
97 * Defined generic Public Key Payload into the protocol
98 specification to send specific type of public keys and
101 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
102 public key or certificate.
104 * Implemented the GETKEY command to the server and to the
105 client library and on user interface.
107 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Made preliminary `make install' work.
111 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Added SilcServerRekey context into silcd/idlist.h.
115 * Added the PFS support as defined in the specification to the
116 SKE protocol. Affected files lib/silcske/*.c.
118 * Added `ske_group' field to the SilcServerRekey context to hold
119 the number of the SKE group that is used with PFS in re-key.
120 Affected file silcd/idlist.h.
122 * Added PFS re-key support to the server. Affected file is
125 * Added silc_protocol_cancel to cancel execution of the next
126 state of the protocol. Affected file is
127 lib/silccore/silcprotocol.[ch].
129 * Added the re-key support with and without PFS to the client
130 library. Re-key is performed once in an hour, by default.
132 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
133 Added silc_client_rekey_callback and silc_client_rekey_final.
134 Affected files are lib/silcclient/protocol.[ch] and
135 lib/silcclient/client.[ch].
137 * Removed the `hmac_key' and `hmac_key_len' fields from the
138 SilcClientConnection structure; not needed. Affected file is
139 lib/silcclient/client.h.
143 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Do not ask whether user wants to use the negotiated private key
146 for private messages, just use it. Affected file is
147 silc/local_command.c.
149 * Added `send_enc_key' and `enc_key_len' fields to the
150 SilcIDListData structure since they are needed in the re-key
151 phase. Affected file is silcd/idlist.[ch].
153 * Implemented the simple re-key protocol into the server.
154 Affected files silcd/server.c and silcd/protocol.[ch]. The
155 re-key will be performed once in an hour, by default.
157 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
158 Added silc_server_rekey, silc_server_rekey_callback and
159 silc_server_rekey_final.
161 * Removed Tunneled flag from the protocol. Updated the code
162 and the specifications.
164 * Adde `pfs' field to the SilcIDListData to indicate whether
165 the PFS is to be performed in the re-key. Affected file is
168 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
171 int64 of at least the xintXX size. If void * is less that 4
172 bytes uint32 * will be used. Defined bool as boolean.
174 * Changed _ALL_ unsigned long and unsigned int to uint32,
175 unsgined short to uint16 in the source tree.
177 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
178 not handle clients that has entry->data.registered == FALSE.
179 They are not in the network anymore. Affected file is
182 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Implemented the sending of the SERVER_SIGNOFF notify in the
185 server. Affected file is silcd/server.c.
187 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
188 Added also silc_notify_payload_encode_args into the
189 lib/silccore/silcnotify.[ch].
191 * Implemented ther SERVER_SIGNOFF notify handling in the server.
192 Affected file silcd/packet_receive.c.
194 * Implemented the SERVER_SIGNOFF notify handling in the client
195 library. Affected file lib/silcclient/client_notify.c. Also,
196 implemnted the printing of the SERVER_SIGNOFF info to the
197 application. Affected file silc/client_ops.c.
199 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
200 if the deleting was successful. Affected file silcd/idlist.[ch].
202 * Added support for public key authentication in the connection
203 authentication protocol in the client library. Affected file
204 lib/silcclient/protocol.c.
206 * Changed the server's silc_idlist_get_clients_by_* interface
207 to support already allocated array so that new entries may be
208 added to pre-allocated array. Affected file silcd/idlist.[ch].
209 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
212 * All command reply functions in the server now calls the
213 pending command callback even if error occured. This way the
214 error will be delivered to the client as well. Affected files
215 silcd/command.c and silcd/command_reply.c.
217 * Fixed INFO command to return local server's info if no server
218 was provided. Affected file lib/silcclient/command.c.
220 * Removed RESTART command for good. Updated the code and the
223 * Rewrote parts of the task system. It is a bit simpler now.
224 Removed unsued task priorities. The affected files are
225 lib/silcutil/silctask.[ch].
227 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Moved the USERS printing from the library to the application.
230 Affected files lib/silcclient/command.c and silc/client_ops.c.
232 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Added channel key re-key support. The re-key is perfomed
237 only by the router and is done once in an hour. Added `rekey'
238 field to the SilcChannelEntry in the server. Affected files
239 silcd/server.c and silcd/idlist.h.
241 * Added silc_task_unregister_by_context into the file
242 lib/silcutil/silctask.[ch].
244 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Added SILC_UMODE_GONE mode to indicate when the client is not
247 present in the SILC network. Added also support to the local
248 command AWAY that will set this mode. Added support of showing
249 "xxx is gone" in WHOIS command. The USERS command shows the
252 * Fixed setting server and router operator privileges in the
253 server's UMODE command. Affected file silcd/command.c.
255 * Merged the SKE KE1 and KE2 payloads into one payload. The
256 new KE payload is equivalent to the old KE2 payload.
258 Cleaned up the SKE Start Payload parsing. It now uses the
259 simple buffer unformatting to do the parsing. A lot faster
262 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
263 to the SKE that is used to indicate whether both of the SKE
264 parties should perform authentication. By default only the
265 responder performs authentication. By setting this flag also
266 the initiator must do authentication. By default it is unset
267 since in normal SKE case, client to server connection, only
268 the responder should do authentication. When doing SKE between
269 two clients both should perform authentication. Updated the
270 code and the protocol specs.
272 * A little fix to IDENTIFY command in the server. Search the
273 client first by hash not nickname. Affected file is
276 * Fixed the silc_client_close_connection to support closing
277 the client to client connections wihtout deleting too much
278 data. Affected file lib/silcclient/client.c.
280 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
281 are received if protocol used to be active but is not anymore
282 the application would crash due to NULL pointer dereference.
283 Affected files silcd/server.c and lib/silcclient/client.c.
285 * Added `hash' field to the SilcClientConnection to include
286 the hash function negotiated in the SKE protocol.
288 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
289 to set the channel founder authentication data. A client can
290 claim the founder rights later by providing the authentication
291 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
292 This way the channel founder can regain the channel founder
293 privileges even it is left the channel. This works only on
294 local server and the client must be connected to the same
295 server to be able to regain the founder rights. Updated the
296 protocol specs accordingly.
298 Added support to the CMODE command in the client to set the
299 founder auth data. Read the README to see how to set it.
301 Added support to the CUMODE command to claim the founder
302 rights. Read the README to see how to do it.
304 Added support for the founder authentication to the Channel
305 Entry in the server. Affected file silcd/idlist.h.
307 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
308 server's CMODE command. Affected file silcd/command.c.
310 * Added the following new functions into lib/silccore/silcauth.[ch]:
311 silc_auth_get_method and silc_auth_get_data.
313 * The server now saves the remote hosts public key to the
314 SilcIDListData pointer. Affected file silcd/protocol.c.
316 * The normal server now does not remove the channel entry from
317 the cache if the founder authentication data is set. It used
318 to remove it if the founder was the last one on the channel on
319 the server and left the channel. The auth data is saved and
320 if the channel is re-joined later the old entry is used with
321 the old auth data. Affected files silcd/command_reply.c and
324 * Removed the `pkcs' field from the SilcIDListData structure
325 in the server; it is not used. Affected file silcd/idlist.h.
327 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Fixed packet processing on slow links. Partial packets were
330 never re-processed because the incoming data buffer was cleared
331 by the application. Application must not directly clear the
332 sock->inbuf, the packet processing routines handle it. Fixed
333 this in client library and in server.
335 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Fixed the WHOIS and IDENTIFY send reply function to really
338 check whether to send list or just one entry. Affected file
341 * Cleaned up the LEAVE command's channel key distribution. The
342 affected file silcd/command.c.
344 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
345 can enforce the channel mode as well. In that case the ID
346 includes the ID of the server. The code now enforces the
347 mode change if the router have different mode than the server.
349 * The notify client operation with CMODE_CHANGE notify can now
350 return NULL client_entry pointer if the CMODE was not changed
351 by client. Application must check for this.
353 * Added <Server ID> argument to INFO command to support server
354 info fetching by Server ID.
356 * Added silc_server_announce_get_channel_users to get assembled
357 packets of channel users of the specified channel. Affected
358 file silcd/server.[ch].
360 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
361 was freed underneath the ID Cache.
363 * Re-announce clients when the server received CHANNEL_CHANGE
364 notify from the router. Affected file silcd/packet_send.c.
366 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
369 crashed since it did not handle the fact that there is no cipher
370 called "3" and didn't check the error condition. Now fixed.
372 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
373 flag. It can be used to send message requests.
375 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Implemented the RESTART command in the client.
379 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
380 notice type messages. Added notice printing to the user
383 * The channel keys are not re-generated if the channel's mode
384 is PRIVKEY, ie private key on the channel exists. Affected
385 files silcd/server.c and silcd/command.c.
387 * Fixed a little bug in channel message delivery when channel
388 private keys are set in the server. Affected file is
391 * Changed the setting on channel->on_channel = TRUE from the
392 silc_client_save_channel_key to the JOIN command reply. The
393 key payload is not received if the private channel key is set.
394 Affected file lib/silcclient/command_reply.c and the
395 lib/silcclient/client_channel.c.
397 * When the CMODE_CHANGE notify is sent and the channel private
398 key mode is removed the channel key must be re-generated in
399 other cells as well. Added this support for the router in the
400 silcd/packet_receive.c.
402 * Added new local command NOTICE to send notice message on
403 channel. Affected file silc/local_command.[ch].
405 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Added new local command ME to the client. It is used to send
408 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
409 some action. Affected file silc/local_command.[ch].
411 * Changed channel_message and private_message client operations
412 to deliver the message flags to the application. Added also
413 the `flags' arguments to the silc_client_send_channel_message
414 and silc_client_send_private_message functions. Affected file
417 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Redefined the Private Message Payload to support private message
420 keys and to support the new private message flags. Updated
421 the protocol specs. Flags makes it possible to have for example
424 * Added new type SilcPrivateMessagePayload and defined an API
425 for it in the lib/silcclient/silcprivate.[ch].
427 * Tested private message private keys successfully. Tested the
428 private message key set, unset and list commands with the new
431 * Redefined the Channel Message Payload to include the channel
432 message flags (equal with private message flags) to support
433 for example CTCP style messages.
435 * Defined some of the message (for channel and private message)
436 flags. Updated the protocol specs and added the flags to the
437 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
439 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added SilcKeyAgreementStatus type to the key agreement routines
442 to indicate the current status and error if one occured.
443 The status types are defined in the lib/silcclient/silcapi.h.
445 * Added new local command KEY that is used to set and unset private
446 keys for channels, set and unset private keys for private messages
447 with remote clients and to send key agreement requests and
448 negotiate the key agreement protocol with remote client. The
449 key agreement is supported only to negotiate private message keys,
450 it currently cannot be used to negotiate private keys for channels,
451 as it is not convenient for that purpose.
453 * Fixed a minor pending callback setting bug in the function
454 silc_client_get_client_by_id_resolve, now the function works.
455 Affected file lib/silcclient/idlist.c.
457 * Added function silc_net_get_local_port to get local bound
458 port by socket. Added to lib/silcutil/silcnet.[ch].
460 * Added `sockets' and `sockets_count' fields to the SilcClient
461 object. They hold the sockets of the listenning sockets in
462 the client. Listenning sockets may be for example the key
463 agreement server. Affected file lib/silcclient/client.[ch].
464 Added functions the silc_client_add_socket and the
465 silc_client_del_socket. They are exported to the application
468 * Added ~./silc/clientkeys to support other client's public keys.
470 * Renamed verify_server_key client operation to verify_public_key
471 and added one argument to indicate the type of the connection
472 (server, client etc.).
474 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Added silc_server_connection_auth_request to handle the
477 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
478 silcd/packet_receive.[ch].
480 * Added silc_server_send_connection_auth_request into the
481 silcd/packet_send.c to send the connection auth request packet.
483 * Cleaned up the silcd/protocol.c a bit and fixed some memory
486 * Fixed the public key authentication in responder side in the
487 server. The `auth_data' pointer includes the SilcPublicKey
488 not the path to the public key. Affected file silcd/protocol.c.
490 * Implemented the public key authentication in the initiator side
491 in the server. Affected file silcd/protocol.c.
493 * Removed the [RedirectClient] config section from the server
494 configuration. Is not needed and I don't want to implement it.
496 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Cleaned up the CMODE command in the server. It now works
499 correctly and supports all the modes defined in the protocol.
500 Affected file is silcd/command.c.
502 * Added `hmac_name' field to the SilcChannelEntry in the server
503 to hold the default HMAC of the channel. It can be set when
504 creating the channel (with JOIN command). Affected files
507 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
508 type to indicate the change of the current cipher and hmac
509 on the channel. Client can safely ignore the <cipher> argument
510 (if it chooses to do so) since the CHANNEL_KEY packet will
511 force the channel key change anyway. The <hmac> argument is
512 important since the client is responsible of setting the new
513 HMAC and the hmac key into use.
515 * Fixed the CMODE command in the client library as well.
517 * Tested CMODE command in router environment successfully.
519 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Show the version of the remote client (or server) when connecting
522 to the server. It is logged to the log file. Affected file
525 * Fixed the KILLED notify handling in the client library. The
526 client must be removed from all channels when receiving the
529 Also, do not remove the client entry when giving the KILL
530 command but when the KILLED notify is received.
532 * Removed silc_idlist_find_client_by_nickname from the server.
533 Not needed anymore. Affected files silcd/idlist.[ch].
535 * Implemented the CHANNEL_CHANGE notify type handling to the
536 server. Affected file silcd/server.c.
540 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Added silc_server_send_notify_invite to send the INVITE
543 notify between routers.
545 * Implemented the INVITE command correctly to the server.
547 * Implemented the INVITE notify type handling in the server.
549 * Implemented the INVITE command to the client library and on the
552 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Added function silc_server_get_client_resolve to find the
555 client entry by ID from all ID lists and then resolve it
556 (using WHOIS) if it cannot be found. Affected file is
559 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Implemented the BAN command to the client library.
563 * The JOIN command in the server now checks the invite list
566 * Changed the silc_command_reply_payload_encode_va and the
567 silc_command_payload_encode_va to support that if argument is
568 NULL it ignores and checks the next argument. Affected file
569 lib/silccore/silccommand.c.
571 * Added silc_server_send_notify_ban to send the BAN notify
572 type between routers.
574 * Chaned the silc_notify_payload_encode to support that if
575 argument is NULL it ignores and checks the next argument.
576 Affected file lib/silccore/silcnotify.c.
578 * Tested ban lists in router environment successfully.
580 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Implemented BAN command to the server, in silcd/command.[ch].
584 * Removed the BAN and INVITE_LIST modes from the CMODE command
587 * Added function silc_string_match to regex match two strings.
588 Affected files lib/silcutil/silcutil.[ch].
590 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Redefined parts of the SilcChannelEntry in the server to support
593 the new ban and invite lists.
595 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Redefined the INVITE command. The same command can be used to
598 invite individuals to the channel but also to manage the invite
599 list of the channel (to add to and remove from the invite list).
600 Updated the protocol specs.
602 * Added new command SILC_COMMAND_BAN that can be used to manage
603 the ban list of the channel. Updated the protocol specs.
605 * Removed the channel modes: the SILC_CMODE_BAN and the
606 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
607 in the CMODE command. The equivalent features are now available
608 using INVITE and BAN commands. Updated the protocol specs.
610 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
611 in the network about change in the current ban list. The notify
612 type is not used by the client.
614 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
615 support the invite lists.
617 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Added new function silc_string_regexify that converts string
620 including wildcard characters into regex string that can
621 be used by the GNU regex library. Added into the file
622 lib/silcutil/silcutil.[ch].
624 Added silc_string_regex_combine to combine to regex strings
625 into one so that they can be used as one regex string by
626 the GNU regex library. Added into the file
627 lib/silcutil/silcutil.[ch].
629 Added silc_string_regex_match to match two strings. It returns
630 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
632 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Imported GNU regex to the soruce tree into lib/contrib.
635 Fixed some compiler warning from the regex.c.
637 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Fixed MOTD command in the server to work in router environment.
641 * Fixed the MOTD command in the client library to support
642 the server argument in the command.
644 * Added `nickname_len' argument to the silc_idlist_add_client
645 in the server, as the `nickname' argument may be binary data
648 * Added silc_idlist_get_channels to return all channels from
651 * Implemented LIST command to the server. Affected file is
654 * Implemented the LIST command to the client library and on the
657 * Added [<user count>] argument to the LIST command reply.
658 With private channels the user count is not shown.
660 * Updated TODO and README.
662 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
664 * The client entry's data.registered must be TRUE even with
665 global client entry on global client list. The data.registered
666 is used to check whether the client is anymore in the network,
667 for example with WHOWAS command so it must be valid.
669 * Fixed the WHOWAS command in the server. It now actually works
670 in router environment. Added function into silcd/command_reply.c
671 silc_server_command_reply_whowas_save.
673 * Added silc_idlist_purge function to the silcd/idlist.c
674 to periodically purge the ID Cache.
676 * Fixed INFO command in the server. It works now in router
677 environment. Added <server name> argument to the INFO command
678 reply. Updated the protocol specs.
680 * Fixed minor bug in silc_idcache_purge to not purge if the
681 expire value is zero.
683 * Fixed various bugs in WHOIS and IDENTIFY command handling as
684 they were buggy because of the WHOWAS information.
686 * Fixed local command MSG to handle the async resolving of
687 the remote client properly. It used to fail the first MSG.
688 Affected file silc/local_command.c.
690 * Added `data_len' field to SilcIDCache context.
692 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Update TODO. Todo in commands in the server.
696 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
699 used by routers as broadcast packet to inform other routers
700 about the changed user mode.
702 Implemented the notify handling in the server. Affected file is
703 silcd/packet_receive.c. Added the function
704 silc_server_send_notify_umode to the silcd/packet_send.[ch].
706 * Added new generic Channel Payload and deprecated the New Channel
707 Payload. The New Channel Payload is now the generic Channel
710 * Added new argument `mode' to the silc_server_send_new_channel
711 as it is required in the Channel Payload now.
713 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
714 and created a new and real SilChannelPayload to represent the
715 new generic Channel Payload. Implemented the encode/decode
716 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
718 * Added silc_server_get_client_channel_list to return the list
719 of channels the client has joined for WHOIS command reply.
720 Affected file silcd/server.[ch].
722 * Implemented the channel list sending in the WHOIS command reply
723 in server and in the client.
725 Implemented the channel list displaying on the user interface
726 as well. Affected file silc/client_ops.c.
728 * Added silc_channel_payload_parse_list to parse list of Channel
729 Payloads. It returns SilcDList list of SilcChannelPayloads.
730 Client for example can use this function to parse the list of
731 channels it receives in the WHOIS command reply. The caller
732 must free the list by calling silc_channel_payload_list_free.
733 Affected files lib/silccore/silcchannel.[ch].
735 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * Added one new argument <user mode> to the WHOIS command reply
738 to return the mode of the user in SILC. Updated the protocol
741 Implemented it to the server and client.
743 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Fixed the mode printing on the user interface on joining.
746 Affected file silc/client_ops.c.
748 * Implemented the UMODE command and user modes in general to the
749 client library and to the user interface.
751 * Implemented the UMODE command to the server.
753 * The server now sends UNKNOWN_COMMAND error status if client sends
754 unknown command. Affected file silcd/command.c.
756 * All server commands now handle the command identifier the right
757 way when sending the command reply to the client. The client can
758 use to identify the command replies with the identifier.
760 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
762 * Added silc_server_get_client_route to resolve the route to
763 the client indicated by the client ID. Affected file is
766 * Added silc_server_relay_packet as general function to relay
767 packet to arbitrary destination. This deprecates functions
768 like _send_private_message_key, _relay_notify etc. Affected
769 file is silcd/packet_send.[ch].
771 Removed silc_server_send_key_agreement,
772 silc_server_send_private_message_key and
773 silc_server_packet_relay_notify functions from the file
774 silcd/packet_send.[ch].
778 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
779 server. Affected file silcd/packet_receive.[ch].
781 * Implemented the KILL command to the client. Implemented the
782 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
783 Affected files lib/silcclient/command[_reply].c and
784 lib/silcclient/client_notify.c. Implemented the KILL notify
785 printing in the user inteface.
787 * Fixed a lot silc_parse_nick memory leaks from the client
788 library in the file lib/silcclient/command.c.
790 * Changed the silc_server_send_notify_on_channels's `sender'
791 argument from SilcSocketConnection to SilcClientEntry to
792 check the sender as entry and not as connection object and not
793 to send to the client provided as argument. The affected file
794 is silcd/packet_send.[ch].
796 * The notify packets that are destined directly to the client used
797 to not to be processed by the server. Now changed that and the
798 server processes all notify packets. After relaying the packet
799 to the client the notify packet is processed in the server.
801 * The silc_server_free_client_data now checks whether there is
802 pending outgoing traffic for the client and purges the data to
803 the network before removing the client entry.
805 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
808 an client is killed from the SILC Network. Updated the protocol
811 Added new function silc_server_send_notify_killed to the
812 silcd/packet_send.[ch].
814 * Added function silc_server_packet_relay_notify to relay notify
815 packets that are destined directly to a client. In this case
816 the server does not process the notify packets but merely relays
817 it to the client. Affected file silcd/packet_send.[ch].
819 Added also silc_server_packet_process_relay_notify to check
820 whereto relay the notify. Affected file is
821 silcd/packet_receive.[ch].
823 * Implemented the KILL command to the server.
827 * Added the backup schema desgined last fall to the protocol
828 specs for everyone to see. The specification is in the
829 *-spec-xx.txt draft and the packet type definitions for the
830 backup routers is in *-pp-xx.txt draft. Thusly, added also
831 new packet type SILC_PACKET_CELL_ROUTERS.
833 * A big security problem in the implementation discovered. The
834 signoff of an client did not cause new channel key generation
835 which it of course should've done. The channel keys must be
836 always re-generated when client leaves (or signoffs) the channel.
837 The silc_server_remove_from_channels funtion now handles
838 the channel key re-generation.
840 * Added `sender' argument to the silc_server_send_notify_on_channels
841 to not to send the client provided as argument. Affected file
842 silcd/packet_send.[ch].
844 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Implemented OPER and SILCOPER commands into the server and
849 * Added silc_auth_verify and silc_auth_verify_data to verify
850 the authentication directly from the authentication payload.
851 It supports verifying both passphrase and public key based
852 authentication. Affected file lib/silccore/silcauth.[ch].
854 * Added `hash' field to the SilcIDListData structure. It is the
855 hash negotiated in the SKE protocol. Affected file is
858 * Slight redesigning of the SilcAuthPayload handling routines.
859 Do not send SilcPKCS but SilcPublicKey as argument.
861 * Implemented the public key authentication support to the
862 serverconfig. The public key is loaded from the provided path
863 and saved as authentication data to void * pointer. Thus,
864 changed the unsigned char *auth_data to void *auth_data;
866 * Fixed SHUTDOWN command to send the reply before the server
867 is shutdown. :) Affected file silcd/command.c.
869 * Fixed fatal bug in CONNECT command. The hostname was invalid
870 memory and server crashed. Affected file silcd/command.c.
872 * Fixed fatal bug in CLOSE command. The server_entry became
873 invalid but was referenced later in the command. Affected file
876 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Fixed fatal bug in failure packet handling. Server ignored
879 the failure and thus crashed when it came.
883 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
886 that the command may be executed only once in (about) 2 seconds.
887 The old SILC_CF_LAG flag is same but allows command bursts up
888 to five before limiting.
890 Added the support for CF_LAG and CF_LAG_STRICT flags to the
891 server code. Various commands now includes the CF_LAG_STRICT
892 flag to disallow any kind of miss-use of the command.
894 * Fixed the silc_buffer_unformat to not to allocate any data
895 if the length of the data is zero. It used to allocate the
896 length + 1. Affected file lib/silcutil/silcbuffmt.c.
898 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Changed the format of AdminConnection configuration section
901 in the server. Added username of the admin to the format.
902 Affected files silcd/serverconfig.[ch].
904 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
905 to return admin configuration data by host, username and/or
908 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Implemented WHOWAS command to the server. Added the functions:
912 silc_server_command_whowas_parse,
913 silc_server_command_whowas_send_reply,
914 silc_server_command_whowas_from_client and
915 silc_server_command_whowas_from_server
917 * Added <Client ID> argument to the WHOWAS command reply. Updated
918 the protocol specs accordingly.
920 * Implemented WHOWAS command and command_reply to the client
923 Implemented the WHOWAS printing on the user interface.
925 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Added new argument to the WHOWAS command reply, the real name.
928 It is an optional argument. Updated the protocol specs.
930 * Added SilcIDCacheDestructor callback that is registered when
931 the SilcIDCache is allocated. The callback is called when
932 an cache entry in the ID Cache expires, or is purged from the
933 cache. Added into lib/silccore/idcache.[ch].
935 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
936 to destruct the client entries when the cache entry expires.
937 Other ID Cache's in server and in the client library ignores
940 * If the ID Cache entry's `expire' field is zero then the entry
941 never expires. Added boolean `expire' argument to the
942 silc_idcache_add function in the lib/silccore/idcache.[ch].
943 If it is TRUE the default expiry value is used.
945 * Added silc_server_free_client_data_timeout that is registered
946 when client disconnects. By default for 5 minutes we preserve
947 the client entry for history - for WHOWAS command.
949 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Added support to the server to enforce that commands are not
952 executed more than once in 2 seconds. If server receives
953 commands from client more frequently, timeout is registered
954 to process the commands. Affected file silcd/command.c.
955 Added new function silc_server_command_process_timeout.
957 * Changed NICK_NOTIFY handling in client library to check that
958 if the client's nickname was changed, so there is no need to
959 resolve anything from the server.
961 * Removed error printing from the WHOIS and IDENTIFY commands.
962 If error occurs then it is ignored silently in the client library.
963 The application, however, may map the received error to
964 human readable error string. The application currently maps
965 the NO_SUCH_NICKNAME error to string.
967 * Made the command status message public to the application. Moved
968 them from lib/silcclient/command_reply.c to
969 lib/silcclient/command_reply.h. The application can map the
970 received command status to the string with the
971 silc_client_command_status_message function.
973 * Added check to the server to check that client's ID is same
974 as the Source ID in the packet the client sent. They must
977 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Added dist-bzip hook to the Makefile.am to make bzip2
980 compressed distributions.
982 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Server now enforces the maximum length for the nickname and
985 the channel as protocol specification dictates. 128 bytes for
986 nickname and 256 bytes for channel name.
988 * Moved the WHOIS printing to the application. The client libary
989 does not print out the WHOIS information anymore, the application
990 must do it. Renamed silc_client_command_reply_whois_print to
991 the silc_client_command_reply_whois_save.
993 The client's idle time is also sent to the application now, and
994 the idle is shown on screen.
996 * Added silc_client_command_reply_identify_save to save the
997 received IDENTIFY entries.
999 * Do not check for channel private keys in message sending and
1000 reception if the channel does not have the PRIVKEY mode set.
1001 Affected file lib/silclient/client_channel.c.
1003 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1006 just surfaced after chaning the JOIN procedure.
1008 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added silc_client_get_clients_by_list to get client entries
1011 from Client ID list, that is returned for example by JOIN
1012 and USERS command replies. The application should use this
1013 function for example when JOIN command reply is received to
1014 resolve the clients already on the channel (library does not
1015 do that anymore as USERS command reply is not used in the JOIN
1016 procedure anymore). Affected files lib/silcclient/silcapi.h and
1017 lib/silcclient/idlist.c.
1019 * JOIN command reply and USERS command reply returns now SilcBuffer
1020 pointers instead of unsigned char pointers when returning
1021 the client list and mode list.
1023 * Added <Client ID> argument to the JOIN command reply, mainly
1024 for the server to identify for which client the command was
1025 originally sent. Updated protocol specs accordingly.
1027 * Added SilcDlist private_key pointer to the SilcChannelEntry
1028 in the client to support the channel private keys. Affected
1029 file is lib/silcclient/idlist.h.
1031 * Added SilcChannelPrivateKey argument to the function
1032 silc_client_send_channel_message so that application can choose
1033 to use specific private ke if it wants to. If it is not provided,
1034 the normal channel key is used, unless private keys are set.
1035 In this case the first (key that was added first) is used
1036 as the encryption key.
1038 * Implemented the support for channel private key handling.
1039 Implemented the following functions:
1041 silc_client_add_channel_private_key,
1042 silc_client_del_channel_private_keys,
1043 silc_client_del_channel_private_key,
1044 silc_client_list_channel_private_keys and
1045 silc_client_free_channel_private_keys
1047 Affected file lib/silcclient/client_channel.c.
1049 * Added the support for the private keys in the channel message
1050 sending and encryption and in the message reception and
1051 decryption. Affected funtions are
1052 silc_client_send_channel_message and silc_client_channel_message.
1054 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Added SKE's key verify callback to the client library's
1057 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1059 * Removed the statement that server (or router) must send USERS
1060 command reply when joining to the channel so that the client
1061 knows who are on the channel. Instead, the client list and
1062 client's mode list is now sent in the JOIN command reply to the
1063 client who joined channel. This is better solution.
1065 * Added function silc_server_get_users_on_channel and function
1066 silc_server_save_users_on_channel to the silcd/server.[ch].
1068 * Removed function silc_server_command_send_users from the
1071 * Do not show topic on the client library anymore. The topic is
1072 sent in the command reply notify to the application and the
1073 application must show the topic now.
1075 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Added client searching by nickname hash into the IDENTIFY and
1078 WHOIS commands in the server as they were clearly missing from
1079 them. Affected file is silcd/command.c.
1081 * Fixed a bug in private message receiving in the client library.
1082 The remote ID was freed and it wasn't supposed, now it is
1085 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Minor fix to the channel payload; allocate the data area, as it
1088 needs to be of specific length.
1090 * If the key agreement port is zero then the operating
1091 system will define the bound port. Affected files are
1092 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1094 * Added new function silc_channel_payload_decrypt into the file
1095 lib/silccore/silcchannel.[ch].
1097 * Moved the channel message etc, check from silc_packet_decrypt
1098 to applications. The library calls now a generic
1099 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1100 when the packet is either normal or special. This was done to
1101 allow more wide range of checking that was not allowed when
1102 the code was in library. Now applications can do virtually any
1103 checks to the packet and return to the library the decision how
1104 the packet should be processed. Affected files are
1105 lib/silccore/silcpacket.[ch].
1107 Added silc_server_packet_decrypt_check to the server and
1108 silc_client_packet_decrypt_check to the client library.
1110 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1111 to send with specified source and destination information.
1113 * Channel message delivery between routers was broken after the
1114 channel key distribution was fixed earlier. The channel key
1115 was used be to distributed to other routers as well which is not
1116 allowed by the protocol. Now this is fixed and channel keys
1117 really are cell specific and the channel message delivery between
1118 routers comply with the protocol specification.
1120 * Fixed various commands in server to check also the global list
1121 for the channel entry and not just the local list. The affected
1122 file silcd/command.c.
1124 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Added assert()s to buffer formatting and unformatting routines
1127 to assert (if --enable-debug) when error occurs. Affected
1128 file: lib/silcutil/silcbuffmt.c.
1130 * Changed to auto-reconnect to check whether the remote host is
1131 router and register the re-connect timeout if it is. It used
1132 to check that whether we are normal server, but router must do
1133 auto-reconnect with another router as well. Affected file
1136 * Removed the [<key len>] option from CMODE command as the cipher
1137 name decides the key length, nowadays. See the defined ciphers
1138 from the protocol specification.
1140 * Added [<hmac>] option to the CMODE command to define the HMAC
1141 for the channel. Added SILC_CMODE_HMAC channel mode.
1143 * Added [<hmac>] option for the JOIN command so that user can
1144 select which HMAC is used to compute the MACs of the channel
1147 * Added Hmac field to the Channel Message Payload. The integrity
1148 of plaintext channel messages are now protected by computing
1149 MAC of the message and attaching the MAC to the payload. The
1150 MAC is encrypted. Now, it is clear that this causes some
1151 overhead to the size of the packet but rationale for this is that
1152 now the receiver can verify whether the channel message decrypted
1153 correctly and also when private keys are set for the channel the
1154 receiver can decrypt the packet with several keys and check from
1155 the MAC which key decrypted the message correctly.
1157 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1158 lib/silccrypt/silccipher.[ch].
1160 * Added silc_hash_len to return the digest length into the
1161 lib/silcrypt/silchash.[ch].
1163 * Rewrote parts of Silc Channel Payload interface in the
1164 lib/silccore/silcchannel.[ch]. The encode function now also
1165 encrypts the packet and parse function decrypts it.
1167 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Fixed a minor formatting bug in the SKE's key material processing.
1170 It actually might have processed the keys wrong way resulting
1173 * Redefined the mandatory HMAC algorithms and added new algorithms.
1174 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1175 and hmac-md5 truncated to 96 bits. The mandatory is now
1176 hmac-sha1-96. Rest are optional (including the one that used
1177 to be mandatory). Rationale for this is that the truncated HMAC
1178 length is sufficient from security point of view and can actually
1179 make the attack against the HMAC harder. Also, the truncated
1180 HMAC causes less overhead to the packets. See the RFC2104 for
1183 * Added new [hmac] configuration section. The SKE used to use
1184 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1185 is of course wrong. The official names that must be proposed in
1186 the SKE are the ones defined in the protocol specification
1187 (hmac-sha1-96 for example). The user can configure any hmac
1188 using any hash function configured in the [hash] section. At
1189 least, the mandatory must be configured.
1191 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1193 * Added HMAC list to the SKE proposal list. It has now both
1194 hash algorithm list and HMAC list. This makes the protocol
1195 incompatible with previous versions. The SKE now seems to work
1196 the way it is supposed to work, for the first time actually.
1198 * Defined plain Hash algorithms to the protocol specification.
1201 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Implemented support for key agreement packets into the server.
1204 Added functions silc_server_key_agreement and
1205 silc_server_send_key_agreement. Other than these functions,
1206 server has nothing to do with this packet.
1208 * Added support for private message key packets into the server.
1209 Added functions silc_server_private_message_key and
1210 silc_server_send_private_message_key.
1214 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1215 called in the protocol's final callback instead in the END
1216 protocol state. This makes a little more sense and in the same
1217 time in client we can use the same protocol routines for normal
1218 key exchange and to key agreement packet handling as well.
1220 * Added to both client's and server's KE protocol context the
1221 SilcSKEKeyMaterial pointer to save the key material. We will
1222 bring the key material to the protocol's final callback by doing
1223 this. The final callback must free the key material.
1225 * Added SKE's packet_send callback into client's KE protocol
1226 context so that the caller can choose what packet sending function
1227 is used. This way we can use different packet sending when
1228 doing normal SKE when doing key agreement packet handling (in
1229 the key agreement packet handling we do not want to encrypt
1232 * Implemented the responder side of the key agreement routines
1233 in the client. The client can now bind to specified port and
1234 accept incoming key negotiation. The key material is passed
1235 to the application after the protocol is over.
1237 * Implemented the processing of incoming Key Agreement packet
1238 in the client. Added function silc_client_key_agreement to
1241 * Implemented the intiator side of the key agreement routines
1242 in the client. The client can now initiate key agreement with
1243 another remote client. The key material is passed to the
1244 application after the protocol is over.
1246 * Created client_keyagr.c to include all the key agreement
1249 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1250 SILC_TASK_CALLBACK except that it is not static.
1252 * Created client_notify.c and moved the Notify packet handling
1253 from the client.[ch] into that file.
1255 * Created client_prvmsg.c and moved all private message and
1256 private message key routines from the client.[ch] into that file.
1258 * Create client_channel.c and moved all channel message and
1259 channel private key routines from the client.[ch] into that file.
1261 * Changed silc_client_get_client_by_id_resolve to resolve with
1262 WHOIS command instead of IDENTIFY command, in the file
1263 lib/silclient/idlist.c.
1265 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Implemented the SKE's responder side to the Client library.
1269 * When FAILURE is received to the protocol do not trust it
1270 blindly. Register a timeout to wait whether the remote closes
1271 the connection as it should do it, only after that process the
1272 actual failure. This was changed to both client and server.
1274 * Added client_internal.h to include some of the structures
1275 there instead of client.h in lib/silcclient/.
1277 * Added function silc_task_unregister_by_callback to unregister
1278 timeouts by the callback function.
1280 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Some "Incomplete WHOIS info" errors has been appearing on the
1283 log files. Took away the entry->userinfo check from WHOIS
1284 reply sending. The entry->userinfo is now " " if client did not
1285 provide one. I thought this was fixed earlier but something
1286 is wrong still. Let's see if the error still appears.
1288 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Fixed a minor bug in the login when the channel key is
1291 re-generated in the server. It used to generate the key in
1292 wrong order and thus caused problems in the channel traffic.
1294 * Fixed a minor bug in channel key distsribution after
1295 KICK command. The key was not sent to the router even though
1298 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Added silc_ske_process_key_material_data as generic routine
1301 to process any key material as the SILC protocol dictates. The
1302 function is used by the actual SKE library but can be used by
1303 applications as well. This relates to the private message keys
1304 and the channel private keys since they must be processed the
1305 same way the normal SILC session keys. The protocol dictates
1306 this. Affected files: lib/silcske/silcske.[ch].
1308 Added also silc_ske_free_key_material to free the
1309 SilcSKEKeyMaterial structure.
1311 * Defined silc_cipher_set_key function to set the key for
1312 cipher without using the object's method function. The affected
1313 files: lib/silccrypt/silccipher.[ch].
1315 * Implemented silc silc_client_add_private_message_key,
1316 silc_client_add_private_message_key_ske,
1317 silc_client_del_private_message_key,
1318 silc_client_list_private_message_keys and
1319 silc_client_free_private_message_keys functions in the
1322 Added functions silc_client_send_private_message_key to send
1323 the Private Message Key payload and silc_client_private_message_key
1324 to handle incoming Private Message Key payload.
1326 * Added Cipher field to the Private Message Key payload to set
1327 the cipher to be used. If ignored, the default cipher defined
1328 in the SILC protocol (aes-256-cbc) is used.
1330 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Removed lib/silcclient/ops.h file.
1334 Redefined parts of the SILC Client Library API. Created new
1335 file silcapi.h that deprecates the ops.h file and defines the
1336 published Client Library API. Defined also private message key
1337 API and channel private key API into the file.
1339 This is the file that the application must include from the
1340 SILC Client Library. Other files need not be included by
1341 the application anymore.
1343 * Added new key_agreement client operation callback and also
1344 defined the Key Agreement library API for the application.
1346 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1349 is used by clients to request key negotiation between another
1350 client in the SILC network. If the negotiation is started it
1351 is performed using the SKE protocol. The result of the
1352 negotiation, the secret key material, can be used for example
1353 as private message key.
1355 Implemented the Key Agreement payload into the files
1356 lib/silccore/silauth.[ch].
1358 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Redefined ciphers for the SILC protocol. Added some new ciphers
1361 and defined the key lengths for the algorithms. Changed the
1362 code accordingly. The default key length is now 256 bits.
1364 * Fixed SKE key distribution function silc_ske_process_key_material
1365 when the key length is more than 128 bits. The default key
1366 length in SILC is now 256 bits.
1368 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1369 to indicate unsupported algorithm.
1371 * Renamed rijndael.c to aes.c and all functions as well.
1373 * Fixed a long standing channel key setting bug in client library.
1374 Weird that it has never surfaced before.
1376 * Fixed bug in channel deletion. If the entire channel is removed
1377 then it must also delete the references of the channel entry
1378 from the client's channel list as the client's channel entry and
1379 the channel's client entry share same memory.
1381 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Implemented CONNECT and SHUTDOWN commands in the client.
1385 * Implemented CLOSE command to the client.
1387 * Added the function silc_idlist_find_server_by_name into the
1388 files silcd/idlist.[ch].
1390 Added the function silc_idlist_find_server_by_conn into the
1391 files silcd/idlist.[ch].
1393 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * DIE command was renamed to SHUTDOWN. Updated the both code
1398 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1399 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1401 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1404 * Added function silc_server_create_connection function to create
1405 connection to remote router. My server implementation actually
1406 does not allow router to connect to normal server (it expects
1407 that normal server always initiates the connection to the router)
1408 so the CONNECT command is only good for connecting to another
1411 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1414 or some other client was kicked from the channel.
1416 Implemented the handling of the notify type to both client
1419 Implemented silc_server_send_notify_kicked to send the KICKED
1420 notify. It is used to send it to the server's primary router.
1422 * Implemented the KICK command into server and client.
1424 * Added `query' argument to the silc_idlist_get_client function
1425 to indicate whether to query the client from server or not if
1428 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1429 to indicate that the client is not channel founder.
1433 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Removed the rng context from SilcPacketContext structure and
1436 changed that the packet routine uses the Global RNG API.
1438 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Added support for quit message that client can "leave" on the
1441 channel when it quits the SILC. It is ditributed inside the
1442 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1444 Added silc_server_free_client_data that will take the
1445 signoff message as argument.
1447 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1449 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * Updated parts of the protocol specification to keep it up
1454 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1456 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1457 payloads in one packet.
1459 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1460 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1461 use now the new List flag.
1463 * Also deprecated the following packet types: REPLACE_ID,
1464 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1466 * Added list support for Notify packet in server.
1468 * Added silc_server_send_notify_channel_change to send the
1469 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1470 the silc_server_send_replace_id.
1472 * Added silc_server_send_notify_nick_change to send the
1473 NICK_CHANGE notify type. Deprecates the function
1474 silc_server_send_replace_id.
1476 * Added silc_server_send_notify_join to send the JOIN notify type.
1477 Deprecates the function silc_server_send_new_channel_user.
1479 * Added silc_server_send_notify_leave to send LEAVE notify type.
1480 Deprecates the function silc_server_send_remove_channel_user.
1482 * Added silc_server_send_notify_cmode and
1483 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1484 types. Deprecates the silc_server_send_set_mode function.
1486 * Added SERVER_SIGNOFF notify type to indicate that server has
1487 quit. This means that all clients on the channel from that
1488 server will drop. This can be also used when netsplit happens.
1490 Deprecated REMOVE_ID packet type since it is not needed anymore
1493 Added silc_server_send_notify_server_signoff to send the
1494 SERVER_SIGNOFF notify type. Deprecates the function
1495 silc_server_send_remove_id.
1497 Added also silc_server_send_notify_signoff to send the
1498 SIGNOFF notify type.
1500 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1501 SILC protocol from this day on. Changed the protocol
1502 specification as well.
1504 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1505 notify type. It is used between routers to notify about
1506 topic changes on a channel.
1508 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1511 * Partly updated the protocol specification to comply with the
1512 changes now made. It is still though a bit outdated.
1514 * The JOIN notify type now takes one extra argument <Channel ID>.
1515 The packet used to be destined to the channel but now the
1516 JOIN type may be sent as list thus it is impossible to
1517 destine it to any specific channel. By adding this argument
1518 it is again possible.
1520 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Added CREDITS file. The CHANGES and CREDITS file will appear
1523 in the distribution as well.
1525 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1528 types in the server's silcd/packet_receive.c.
1530 * Implemented CMODE and CUMODE to work in router environment.
1532 * Fixed minor encoding and decoding buglet from the
1533 lib/silccore/silcmode.c.
1535 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1538 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1540 * Changed all SilcConfigServer* and silc_config_server* to
1541 SilcServerConfig* and silc_server_config*, respectively.
1544 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Associated the ID (client or server ID) to the Authentication
1547 Payload to avoid any possibility of forging. Updated the
1548 protocol specification and the code accordingly.
1550 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * The RSA key length is now save to the RsaKey context in the
1553 key generation process in lib/silccrypt/rsa.c. The key length
1554 is now used to figure out the maximum size of the block allowed
1555 to be encrypted/signed.
1557 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1558 is equivalent to the silc_mp_mp2bin but does not allocate any
1561 * Changed silc_mp_mp2bin API to take length argument. If it is
1562 non-zero then the buffer is allocated that large. If zero, then
1563 the size is approximated using silc_mp_sizeinbase, which however
1566 * Created Global RNG API which is global RNG that application can
1567 initialize. After initializing, any routine anywhere in the
1568 code (including library) can use RNG without allocating a new
1569 RNG object. This was done to allow this sort of use of the
1570 RNG in code that has no chance to allocate RNG object. All
1571 applications currently allocate this and many routines in the
1572 library use this. Affected file lib/silccrypt/silcrng.[ch].
1574 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1575 it to use the Global RNG API.
1577 * Defined Authentication Payload into protocol specification that
1578 is used during SILC session to authenticate entities. It is
1579 used for example by client to authenticate itself to the server
1580 to obtain server operator privileges.
1582 Implemented this payload into the lib/silccore/silcauth.[ch].
1583 Implemented also routines for public key based authentication
1584 as the new protocol specification dictates.
1586 Moved definitions of different authentication methods from
1587 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1589 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1590 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1591 silc_pkcs_verify_with_hash functions into the file
1592 lib/silccrypt/silcpkcs.[ch].
1594 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * The client entry's userinfo pointer must be always valid.
1597 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1598 will fail since it requires the userinfo. Now, the userinfo
1599 is allocated as "" if actual userinfo does not exist. Actually,
1600 it must exist and it is totally Ok to drop client connections
1601 that does not announce the userinfo. However, we will make
1602 this workaround for now.
1604 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1605 to return the remote port by socket.
1607 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1610 SILC_SERVER_PENDING_EXEC and added an new macro
1611 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1612 data or when error occurs while processing the pending command.
1614 Added new argument `destructor' into silc_server_command_pending
1615 and to the SilcServerCommandPending object. This destructor is
1616 now called after calling the pending callback or if error occurs
1617 immediately. If error occurs the actual pending callback won't
1618 be called at all - only the destructor. The destructor may be
1619 NULL if destructor is not needed.
1621 All this applies for client library code as well. Similar
1622 changes were made there as well for the pending commands.
1624 In the client, the application must now allocate the
1625 SilcClientCommandContext with the silc_client_command_alloc
1628 * Added reference counter to the SilcServerCommandContext. Added
1629 function silc_server_command_alloc and silc_server_command_dup
1632 Same type of functions added to the client library for the same
1635 * Removed the cmd_ident from IDListData away since it is now
1636 global for all connections. It is the command identifier used
1637 in command sending and with pending commands. The affected file
1640 * Added reference counter to the SilcSocketConnection objecet to
1641 indicate the usage count of the object. The object won't be
1642 freed untill the reference counter hits zero. Currently only
1643 server uses this, and client ignores it. The client must be
1644 set to use this too later. The affected files are
1645 lib/silccore/silcsockconn.[ch]. Added also the function
1646 silc_socket_dup to increase the reference counter.
1648 This was mainly added because it is possible that the socket
1649 is removed underneath of pending command or other async
1650 operation. Now it won't be free'd and proper DISCONNECTING
1651 flags, etc. can be set to avoid sending data to connection that
1652 is not valid anymore.
1654 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1655 the connection. After that it sets SILC_SET_DISCONNECTED.
1656 It is, however, possible that the socket data is not still freed.
1657 The silc_server_packet_process now checks that data is not
1658 read or written to connection that is DISCONNECTED. The socket
1659 get's freed when the reference counter hits zero.
1661 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Changed the client operation API: channel_message operation's
1664 `sender' is now the client entry of the sender, not the nickname
1665 and the `channel' is the channel entry, not the channel name.
1667 In the private_message operation the `sender' is now also the
1668 client entry of the sender not the nickname.
1670 Affected file is lib/silcclient/ops.h and all applications
1671 using the client operations.
1673 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Moved the calling of ops->connect() from connect_to_server_final
1676 into receive_new_id functin since that is the point when the
1677 client is actually allowed to send traffic to network. The
1678 affected file is lib/silcclient/client.c.
1680 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1683 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1684 (if needs broadcasting) instead of broadcasting the packets one
1685 by one which would make a burst in the network traffic.
1687 * Added `broadcast' argument to the functions in silcd/server.[ch]
1688 silc_server_create_new_channel[_with_id] to indicate whether
1689 to send New Channel packet to primary router.
1691 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Added new function into the silcd/server.[ch] files:
1694 silc_server_create_new_channel_with_id to create new channel with
1695 already existing Channel ID.
1697 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1698 lib/silccore/silcpacket.h. This packet is used t send list of
1699 Set Mode payloads inside one packet. Server uses this to set
1700 the modes for the channels and clients on those channels, that it
1701 announced to the router when it connected to it. The protocol
1702 specification has been updated accordingly.
1704 * The silc_server_new_channel did not handle the packet coming
1705 from normal server as it normally does not send that. However,
1706 when it announces its channels it does send it. Implemented
1707 the support for that.
1709 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1710 into the file lib/silccore/id.h.
1712 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Fixed memory leaks in the functions silc_idlist_del_client,
1715 silc_idlist_del_channel and silc_idlist_del_server in the file
1716 silcd/idlist.c. All of those leaked like a sieve.
1718 * Fixed some small memory leaks in the client's function
1719 silc_client_notify_by_server.
1721 * Added functions into silcd/server.c: silc_server_announce_clients,
1722 silc_server_announce_channels and silc_server_announce_server.
1723 These functions are used by normal and router server to announce
1724 to its primary router about clients, channels and servers (when
1725 router) that we own. This is done after we've connected to the
1728 These functions effectively implements the following packet types:
1729 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1730 and SILC_PACKET_NEW_ID_LIST.
1732 * Added new functions into the silcd/packet_receive.[ch]:
1733 silc_server_new_id_list, silc_server_new_channel_list and
1734 silc_server_new_channel_user_list to handle the incoming
1735 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1737 * Added support of changing Channel ID in the function
1738 silc_server_replace_id. If the server that announces a channel
1739 to the router already exists in the router (with same name but
1740 with different Channel ID), router is responsible to send
1741 Replace ID packet to the server and force the server to change
1742 the Channel ID to the one router has.
1744 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1745 client that the Channel ID has been changed by the router. The
1746 normal server sends this to the client. Client must start using
1747 the new Channel ID as the channel's ID.
1749 Implemented handling of this new type into lib/silcclient/client.c
1750 into the function silc_client_notify_by_server.
1752 * Added new function silc_idlist_replace_channel_id into the files
1753 silcd/idlist.[ch] to replace the Channel ID.
1755 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Call silc_server_command_identify_check always when processing
1758 the IDENTIFY command in silcd/command.c
1760 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1763 send keepalive packets. The packet can be sent by clients,
1764 servers and routers.
1766 Added function silc_socket_set_heartbeat into the file
1767 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1768 If not set, the heartbeat is not performed. The actual
1769 heartbeat is implemented in the low level socket connection
1770 library. However, application is responsible of actually
1773 Added silc_server_send_heartbeat to send the actual heartbeat
1774 packet into silcd/packet_send.[ch]. Server now performs
1775 keepalive with all connections.
1777 * Added silc_task_get_first function into lib/silcutil/silctask.c
1778 to return the timeout task with shortest timeout. There was a bug
1779 in task unregistration that caused problems. TODO has been
1780 updated to include that task system must be rewritten.
1782 * The client library will now resolve the client information when
1783 receiving JOIN notify from server for client that we know but
1784 have incomplete information.
1786 * Rewrote parts of silc_server_remove_from_channels and
1787 silc_server_remove_from_one_channel as they did not remove the
1788 channel in some circumstances even though they should've.
1790 * Encryption problem encountered in server:
1792 The LEAVE command used to send the Channel Key packet to the
1793 router immediately after generating it. However, the code
1794 had earlier sent Remove Channel user packet but not immediately,
1795 ie. it was put to queue. The order of packets in the router
1796 was that Channel Key packet was first and Remove Channel User
1797 packet was second, even though they were encrypted in the
1798 reverse order. For this reason, MAC check failed. Now, this
1799 is fixed by not sending the Channel Key packet immediately but
1800 putting it to queue. However, this is more fundamental problem:
1801 packets that are in queue should actually not be encrypted
1802 because packets that are sent immediately gets encrypted
1803 actually with wrong IV (and thus MAC check fails). So, packets
1804 that are in queue should be encrypted when they are sent to
1805 the wire and not when they put to the queue.
1807 However, the problem is that the current system has not been
1808 designed to work that way. Instead, the packet is encrypted
1809 as soon as possible and left to the queue. The queue is then
1810 just purged into wire. There won't be any fixes for this
1811 any time soon. So, the current semantic for packet sending
1814 o If you send packet to remote host and do not force the send
1815 (the packet will be in queue) then all subsequent packets to the
1816 same remote host must also be put to the queue. Only after the
1817 queue has been purged is it safe again to force the packet
1820 o If you send all packets immediately then it safe to send
1821 any of subsequent packets through the queue, however, after
1822 the first packet is put to queue then any subsequent packets
1823 must also be put to the queue.
1825 Follow these rules and everything works fine.
1827 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added new function silc_server_remove_clients_by_server to
1830 remove all client entries from ID list when the server connection
1831 is lost. In this case it is also important to invalidate all
1832 client entires as they hold the invalid server entry. This
1833 fixes fatal bug when server has lost connection and will reconnect
1836 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * Made some sanity checks to silc_server_daemonise like to check
1839 whether the requested user and group actually exists.
1841 * Added sanity check to SKE's silc_ske_responder_finish to check
1842 that the public and private key actually is valid.
1844 * Invalidate the client's nickname when receiving Replace ID
1845 packet and the Client ID is being replaced. This means that the
1846 server will query the nickname if someone needs it (client)
1849 * Sort the ID Cache in client library when the ID Cache data
1850 has changed (needs sorting).
1852 * Do not allow for SILC client to create several connections to
1853 several servers. The client does not support windows right now
1854 and generating multiple connections causes weird behaviour.
1856 Irssi-silc client does support windows and can handle several
1857 connections without problems, see: www.irssi.org and SILC plugin.
1859 * Fixed some places where client was added to the IDList. The
1860 rule of thumb is following (in order to get everything right):
1861 If the client is directly connected local client then the
1862 `connection' argument must be set and `router' argument must be
1863 NULL to silc_idlist_add_client function. If the client is not
1864 directly connected client then the `router' argument must
1865 bet set and the `connection' argument must be NULL to the
1866 silc_idlist_add_client function.
1868 * The funtion silc_server_packet_send_local_channel actually did
1869 not check whether the client was locally connected or not. It
1870 does that now. Fixed a bug related to LEAVE command.
1872 * Fixed Remove Channel User payload parsing bug in server's
1873 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1875 * The server's silc_server_save_channel_key now checks also the
1876 global ID list for the channel as it might not be in the local
1877 list. Fixed a bug related to LEAVE command.
1879 * Is this the end of the [<unknown>] buglet that has been lurking
1880 around for a long time? A little for loop fix in server's
1881 silc_server_command_whois_parse that is used by both IDENTIFY
1882 and WHOIS command. At least, this was a clear bug and a cause
1883 of one type of [<unknown>] buglet.
1885 * WHOIS and IDENTIFY commands call the function
1886 silc_server_command_[whois/identify]_check function even if
1887 we are not router server.
1889 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * Added --with-gmp configuration option. If set the GMP
1892 is always compiled in the SILC source tree. If not set then
1893 it is checked whether the system has the GMP3 installed. If
1894 it has then the GMP won't be compiled (the system's headers
1895 and library is used), if it doesn't have it then the GMP is
1896 compiled in the SILC source tree.
1898 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Changed RSA private exponent generation to what PKCS #1
1901 suggests. We try to find the smallest possible d by doing
1902 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1903 not security fix but optimization.
1905 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * Added new config entry [Identity] to fork the server and run
1908 it as specific user and group. A patch from Bostik.
1910 * Imported Dotconf configuration library into lib/dotconf.
1911 This will be used to create the SILC configuration files later.
1912 It will appear in the distsribution after this commit.
1914 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * A big code auditing weekend happening. Auditing code for
1917 obvious mistakes, bugs and errors. Also, removing any code
1920 Removed files for being obsolete:
1922 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1923 inline in the file lib/silcutil/silcbuffer.h)
1925 o lib/silcutil/silcbufutil.c (the header has inline versions)
1927 Changed code to fix possible error conditions:
1929 o The buffer formatting routines now check that the destination
1930 buffer really has enough space to add the data. This applies for
1931 both buffer formatting and unformatting
1932 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1933 unformatting was changed to accomodate following rules:
1934 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1935 sent to the function while XXX_*STRING will not allocate or copy
1936 the data into the buffer. Instead it sets the pointer from the
1937 buffer into the pointer sent as argument (XXX_*STRING used to
1938 require that the pointer must be allocated already). This change
1939 makes this whole thing a bit more consistent and more optimized
1940 (note that the data returned in the unformatting with XXX_*STRING
1941 must not be freed now). The routines return now -1 on error.
1943 o Tried to find all code that use buffer_format and buffer_unformat
1944 and added return value checking to prevent formatting and
1945 especially unformatting errors and possible subsequent fatal
1948 o Changed ske->x and ske->KEY to mallocated pointers in
1949 lib/silcske/silcske.h. Fixed possible data and memory leak.
1951 o Added return value checking to all *_parse* functions. Fixed
1952 many memory leaks as well.
1954 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1955 so that buffer overflows would not happen. All code now also
1956 checks the return value as it can fail.
1958 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Added reconnection support to server if the normal server looses
1961 its connection to the router (for example if router is rebooted).
1962 The server performs normal reconnection strategy implemented
1963 to the server. Affected file silcd/server.c.
1965 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Added new packet type SILC_PACKET_SET_MODE that is used to
1968 distribute the information about changed modes (for clients,
1969 channels and clients channel modes) to all routers in the
1970 network. Updated the protocol specification accordingly.
1972 Added functions into silcd/packet_send.c and
1973 silcd/packet_receive.c: silc_server_send_set_mode,
1974 silc_server_set_mode.
1976 Added new files silcmode.[ch] into lib/silccore that implements
1977 the encoding and decoding of Set Mode Payload. Added new type
1978 SilcSetModePayload. Moved the definitions of different modes
1979 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1981 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Oops, a little mistake in server's connection authentication
1984 protocol. The protocol is not ended with FAILURE but with
1985 SUCCESS if the authentication is Ok. :) Affected file is
1988 * Implemented NICK_CHANGE notify handling in server in the file
1989 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1990 the local clients on the channel. After the changing nickname
1991 in router environment snhould work and the [<unknown>] nickname
1992 should appear no more.
1994 The silc_server_replace_id function that receives the Replace ID
1995 payload now sends the NICK_CHANGE notify type also in the file
1996 silcd/packet_receive.c
1998 * Changed WHOIS and IDENTIFY command to support the maximum amount
1999 of arguments defined in protocol specs (3328 arguments). This
2000 fixed a bug that caused problems when there were more than three
2003 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Added extra parameter, command identifier, to the
2006 silc_client_send_command so that explicit command identifier
2009 Changed that ID list routines uses specific command identifier
2010 when sending WHOIS/IDENTIFY requests to the server so that they
2011 can be identified when the reply comes back.
2013 Affected files lib/silcclient/command.[ch],
2014 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2016 * Added `sender' argument to silc_server_packet_send_to_channel
2017 to indicaet the sender who originally sent the packet to us
2018 that we are now re-sending. Ignored if NULL. Affected file
2019 silcd/packet_send.[ch].
2021 * Added some server statistics support in silcd/server_internal.h
2022 SilcServerStatistics structure and around the server code. Also
2023 send some nice statistics information when client is connecting
2026 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * Fixed channel ID decoding in server's JOIN command reply in
2029 silcd/command_reply.c
2031 * Fixed braodcasting of replace ID payload to not to send it if
2032 we are standalone server in silcd/packet_receive.c.
2034 * Fixed all channel message sending routines to not to send
2035 packets to clients that has router set, since they are routed
2036 separately in the same function earlier. Affects file
2037 silcd/packet_send.c and all channel packet sending functions.
2039 * In USERS reply, res_argv[i] are not allocated, the table
2040 is allocated. Thus changed that free the table, not its
2043 * In server's whois_check and identify_check if the client is
2044 locally connected do not send any WHOIS commands - they are not
2047 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Fixed some minor bugs in client when sending WHOIS command. The
2050 arguments was in wrong order.
2052 * Removed statis function add_to_channel from server in
2053 silcd/command.c that was previously used with the joining but
2056 * Tested USERS command in router environment successfully with two
2057 routers, two servers and two clients.
2059 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Reorganized the USERS command and command reply in client library
2062 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2063 When the command is given by user we register a pending command
2064 callback that will reprocess the command after the reply has been
2065 received from the server. When reprocessing the packet we then
2066 display the information. Thus, the USERS information is displayed
2067 now in the command callback instead of in the command reply
2068 callback. The processing of the command is same as previously
2069 when server has sent the command reply in the JOINing process.
2071 * Added to USERS command in silcd/command_reply.c to join the client,
2072 we didn't use to know about, to the channel after we've created
2073 a client entry for it. Also, for clienet we did know already still
2074 check whether it is on the channel or not and add it if not.
2076 * Removed silc_server_command_join_notify as the function and its
2079 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Changed the client's pending command handling to the same as the
2082 server's pending command handling. It is also now possible to
2083 execute command reply functions from other command reply
2084 function as the function callbacks for commands and command
2085 replies are one and same. The pending commands are not static
2086 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2087 in client connection context. Thus, pending commands are server
2088 connection specific as it is convenient.
2090 Changed the function silc_client_command_pending and
2091 silc_client_command_pending_del and added new function
2092 silc_client_command_pending_check. Removed the
2093 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2096 * Added cmd_ident, current command identifier, to the client
2097 connection context in lib/silcclient/client.h to keep track on
2098 command identifiers used in command sending. Client's command reply
2099 function handling now supports the mandatory command identifiers.
2101 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2102 funtions in client to fully support pending command callbacks.
2104 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2105 as one of the arguments to the application in the command reply
2108 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2109 before first releasing SILC but came back. Now it is removed again
2110 and should come back nomore. The FORWARDED flag was used only
2111 by the JOINing procedure by forwarding the command packet to router.
2112 Now, the JOINing procedure has been changed to more generic (due
2113 to various router environment issues) and FORWARDED is not needed
2114 anymore for anything. The protocol specification is yet to be
2117 Now, removed silc_server_packet_forward from server and the flag
2118 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2120 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Renamed NAMES command to USERS command. The NAMES was named that
2123 due to historical reasons. Now it is renamed. Also, rewrote
2124 parts of the USERS command. The nickname list is not sent anymore
2125 by the server. Only Client ID and mode lists are sent in the USERS
2126 command. Changed this also to the protocol specification.
2128 The client now resolves the names and stuff after it receives
2129 the USERS list from the server when joining to the channel.
2131 * WHOIS and IDENTIFY commands has been changed to support multiple
2132 Client ID's per command. One can now search for multiple users
2133 in the network by sending only one WHOIS or IDENTIFY command.
2134 Changed the code and the protocol specifications.
2136 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2137 uses silc_server_command_whois_parse to parse the request. */
2139 * If normal server, do not parse the WHOIS and IDENTIFY requests
2140 before sending it to the router. Saves some time.
2142 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Fixed JOIN command on client library. Wrong number of arguments
2145 used to crash the client.
2147 * Added silc_server_channel_has_global function to check whether
2148 channel has global users or not.
2150 * Added silc_server_channel_has_local function to check whether channel
2151 has locally connected clients on the channel.
2153 * The silc_server_remove_from_one_channel now checks whether the
2154 channel has global users or not after given client was removed from
2155 the channel. It also checks whether the channel has local clients
2156 on the channel anymore. If it does not have then the channel entry
2157 is removed as it is not needed anymore.
2159 * The silc_server_notify now checks on JOIN notify whether the joining
2160 client is one of locally connected or global. If it is global then
2161 the channel has now global users on the channel and that is marked
2162 to the channel entry. Also, it now saves the global client to
2163 global list who is joining and JOINs it to the channel. This is
2164 for normal server, that is.
2166 Changed silc_server_send_notify_on_channel,
2167 silc_server_packet_relay_to_channel and
2168 silc_server_packet_send_to_channel check if we are normal server
2169 and client has router set (ie. global client) do not send the
2170 message to that client, as it is already routed to our router.
2172 * Implemented LEAVE notify type handling in silc_server_notify
2175 * Tested LEAVE command in router environment successfully. Tested
2176 with two routers, two servers and two clients.
2180 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2182 * Implemented SIGNOFF notify type handling in silc_server_notify
2185 * silc_server_remove_id now removes the client entry from all channels
2186 it has joined and thusly sends SIGNOFF notify type.
2188 * Rewrote the NAMES list generation in server by removing two excess
2189 loops. The lists are created now inside one loop.
2191 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * silc_server_remove_channel_user checks now also global list
2194 for channel and client.
2196 * silc_server_new_channel_user checks now both local and global
2197 list for channel and client. Fixed a bug in client id decoding.
2198 Used to decode wrong buffer.
2200 * silc_server_channel_message checks now both local and global
2201 list for channel entry.
2203 * Tested channel joining (hence JOIN) in router environment
2204 successfully. Tested with two routers, two servers and two
2207 * Tested channel message sending in router environment successfully.
2209 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Added silc_server_save_channel_key into server.[ch] to save the
2212 received channel key in Channel Key payload processing. It is
2213 also used in JOIN command reply handling.
2215 Equivalent function silc_client_save_channel_key added into
2216 client.[ch] into client library.
2218 * Changed JOIN command reply to send information whether the channel
2219 was created or not (is existing already) and the channel key
2220 payload. Changed protocol specs accordingly.
2222 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2223 the request was sent by ID and not by nickname. Crashed on
2226 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2229 now correctly save the received data.
2231 * silc_server_free_sock_user_data now notifies routers in the
2232 network about entities leaving the network.
2234 At the same time implemented functions silc_server_remove_id
2235 and silc_server_send_remove_id to receive and send REMOVE_ID
2236 packets. The packet is used to notify routers in the network
2237 about leaving entities. The ID removed will become invalid in
2240 * Added function silc_idlist_del_server into server. Removes and
2241 free's server entry from ID list.
2243 * silc_server_private_message function now checks, if we are router,
2244 that the destination ID really is valid ID, naturally.
2246 * In router when NEW_ID packet is received (for new client) the
2247 hash of the Client ID is saved in the ID Cache but the
2248 client->nickname is set to NULL, instead of putting the hash
2251 IDENTIFY command now also checks that client->nickname must be
2252 valid. If it is not if will request the data from the server who
2253 owns the client. Added new function
2254 silc_server_command_identify_check.
2256 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2257 to set the command to already allocated Command Payload.
2259 * Tested private message sending in router environment with two
2260 routers, two servers and two clients. Fixed minor bugs and now
2263 * Fixed segfault from client's NAMES command. Used to crash if
2266 * Forwarded packets must not be routed even if it is not destined
2267 to the receiver. Changed server code comply with this.
2269 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added `require_reverse_mapping' boolean value to ServerParams
2272 structure. If TRUE (not default) the server will require that
2273 the connecting host has fully qualified domain name.
2275 If the reverse mapping is not required and hostname could not be
2276 found the IP address is used as hostname.
2278 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * Implemented version string checking to both client and server.
2281 The check is incomplete currently due to the abnormal version
2282 strings used in development version of SILC.
2284 * Changed all command functions in server to use the new
2287 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Changed char *data to unsigned char *data in ID Cache system to
2290 support binary data as ID Cache data. Changed code to support
2291 binary data in lib/silccore/idcache.c.
2293 * Renamed silc_server_packet_relay_command_reply to
2294 silc_server_command_reply as it is normal packet receiving
2295 function. Rewrote the function to accept command replys for
2296 servers and not only for clients.
2298 * Mark remote router always as registered server if we are connecting
2299 to it. Otherwise, commands sent by the router to us are ignored.
2301 * All ID List find routines now returns the ID Cache Entry pointer
2302 as well if requested.
2304 * WHOIS command works now in router environment, tested with two
2305 routers, two servers and two clients.
2307 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2308 in router environment (as it is almost equivalent to WHOIS) but
2309 hasn't been tested thoroughly. Added new functions:
2311 silc_server_command_identify_parse
2312 silc_server_command_identify_send_reply
2313 silc_server_command_identify_from_client
2314 silc_server_command_identify_from_server
2316 * Disabled route cache adding because adding two different ID's with
2317 same IP replaces the old cache entry thus giving wrong route.
2318 The entry->router->connection is always the fastest route anyway
2319 so route cache may not be needed. Of course, new routes maybe
2320 established after receiving the ID when the entry->router->connection
2321 might not be anymore the most optimal.
2323 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Add route cache for received ID for fast routing.
2327 * Added silc_server_packet_route to route received packet on router
2328 that is not destined to us.
2330 * Renamed silc_server_get_route to silc_server_route_get.
2332 * Added id_string and id_string_len fields into SilcServer to
2333 include encoded ServerID for fast comparing without excess
2334 encoding of the ID's.
2336 * Cleaned up WHOIS command on server side. Added following static
2339 silc_server_command_whois_parse
2340 silc_server_command_whois_check
2341 silc_server_command_whois_send_reply
2342 silc_server_command_whois_from_client
2343 silc_server_command_whois_from_server
2345 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2346 arguments in command replies. All command functions should be
2347 updated to use this macro.
2349 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Minor typo fixes on command reply handling on server.
2353 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Added silc_server_command_add_to_channel internal routine to add
2356 the client to the channel after router has created the channel and
2357 sent command reply to the server.
2359 * Added generic silc_server_send_command to send any command from
2362 * Use static buffer with ID rendering instead of duplicating data.
2364 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Fixed a channel user mode bug when joining to a channel server gave
2367 everybody channel founder rights, oops.
2369 * We mark ourselves as the router of the incoming server connection
2370 if we are router ourselves. This way we can check in some packet
2371 sending functions whether it is locally connected server. For
2372 incoming router connections we put NULL.
2374 * For router sending packets locally means now always sending the
2375 packet cell wide; to local clients and local servers. For normal
2376 server sending packet locally means sending it to only local
2379 * Fixed the JOIN command to really work in router environment. If the
2380 channel is created it is always created by the router. Router is
2381 also responsible of making the initial joining to the channel,
2382 sending JOIN notify to the sending server and distributing
2383 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2384 does not exist server doesn't do anything else but forward the
2385 command to the router which performs everything.
2387 * Added silc_server_send_channel_key function to send the Channel Key
2390 * Added silc_server_create_channel_key to create new channel key. The
2391 channel key is now re-generated everytime someone joins or leaves
2392 a channel, as protocol dictates. Note: channel->key_len is the
2395 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2398 packet_receive.[ch] to separate packet sending and receiving
2399 routines. The server.[ch] now includes everything else including
2400 actual packet processing (writing and reading data) and other
2403 Renamed silc_server_private_message_send_internal to
2404 silc_server_send_private_message. The routine is still though
2405 used only to relay private messages as server does not send
2406 private messages itself.
2408 Renamed silc_server_new_channel to silc_server_create_new_channel
2409 and added new function sicl_server_new_channel that handles the
2410 incoming New Channel packet. Added also new sending function
2411 silc_server_send_new_channel to send New Channel Payload.
2413 * Added new function silc_server_notify to process incoming notify
2414 packet to the server/router. Server may then relay the notify
2415 to clients if needed.
2417 * Added new function silc_server_new_channel_user to process incoming
2418 New Channel User packet. Router will redistribute the packet and
2419 send JOIN notify to its local clients and locally connected servers
2420 if needed. Normal server will send JOIN notify to its local client
2421 on same channel when received this packet. Added also corresponding
2422 sending function silc_server_send_new_channel_user to sent the
2425 * Added boolean route argument to send_notif_to_channel and
2426 packet_send_to_channel functions to attempt to route the packet
2427 if it is TRUE and send only locally if it is FALSE.
2429 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * silc_server_replace_id now broadcasts the received replace ID
2432 packet if it is not broadcast packet already. The router must
2433 broadcast to inform other routers about changed ID.
2435 * Added backpointer to server's router into SilcServer context in
2436 silcd/server_internal.h.
2438 * Fixed silc_server_packet_broadcast to send correct broadcast
2441 * The channel key is now distributed to the local client as soon
2442 as it is received from the router (in router environment) so that
2443 no other packet may be sent for the channel until client has
2446 * silc_server_remove_channel_user now broadcasts the received
2447 Remove Channel User packet if it is not broadcast packet already.
2448 The router must broadcast to inform other routers about removed
2451 * Added users field into SilcPacketContext that is a reference count
2452 of the context. One can increase the reference count by calling
2453 silc_packet_context_dup which is now changed to just increase the
2454 reference count instead of duplicating the data. The reference
2455 count is decresed by calling silc_packet_context_free that will
2456 free the data after the reference count hits zero.
2458 For now on the packet context and everything allocated into it
2459 (including the raw packet from network) must be freed by calling
2460 the new silc_packet_context_free function. Added also new function
2461 silc_packet_context_alloc that must be used now to allocate the
2462 context. This also means that if a routine is asynchronous from
2463 silc_[client/server]_packet_parse_type the packet context must
2464 be duplicated by calling silc_packet_context_dup. Otherwise it
2465 gets free'd after silc_[client/server]_packet_parse_type returns.
2466 Also, one must remember that if packet is duplicated then its
2467 reference count must be decresed by calling the free function as
2468 many times as it was duplicated.
2470 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2471 from both client and server.
2473 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Made joining to a channel working in router environment.
2477 * Cleaned up JOIN command on server side and create function
2478 silc_server_command_join_channel internal routine to make the
2481 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Changed silc_command_pending list to SilcDList. Also, added
2484 `ident' field to SilcServerCommandPending structure to identify
2485 the reply and to call correct callback.
2487 Added silc_server_command_pending_check function to replace the
2488 corresnponding macro. The silc_command_pending list is not
2491 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2492 to set identifier to previously allocated Command Payload. It
2493 is used to set identifier for command when resending Command
2496 * Added silc_command_payload_encode_payload to encode Command
2497 Payload buffer from SilcCommandPayload structure.
2499 * Added silc_argument_payload_encode_payload to encode Argument
2500 payload buffer from SilcArgumentPayload structure.
2502 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Changed WHOIS command to support router connection on server side.
2505 The whois request is always sent to router unless the server is
2506 standalone server. After server has received the reply from the
2507 router will it send the reply to the client.
2509 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2510 broadcast received broadcast packet. The function is used only
2511 by router. The broadcast packet is always sent to the router's
2514 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2515 render given ID to printable string, for log files for example.
2517 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Made basic router to router connections working. At least they
2520 can now connect to each other but nothing really works the way
2521 they are supposed - yet.
2523 * Added new initiator token to RouterConnection configuration
2524 file in silcd/serverconfig.[ch]. It is used to tell whether we
2525 are the initiator to the remote router or whether we'll expect
2526 the other end to connect.
2528 * Moved registering of listener task to silc_server_init, hence
2529 the server starts listenning as soon as it is run, even if it
2530 does not have connections to other routers. Let's see how well
2533 * Changed default connection retry timeouts for more suitable in
2536 * Removed cipher and such arguments from silc_idlist_add_client
2537 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2538 Added new function silc_idlist_add_data to add the keys and stuff
2541 * Added SilcIDListData structure and added it to SilcClientEntry
2542 and SilcServerEntry as their first field in the structure. This
2543 way we can explicitly cast the ID entries to the SilcIDListData
2544 structure and get common data for the entries. In past, we had
2545 to first check what type of connection it is and then cast it to
2546 correct ID entry type. Now, we can directly cast the opaque
2547 pointer to the SilcIDListData (no matter what ID entry it actually
2548 is) and get the data needed.
2550 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2553 in some circumstances even if threre were timeout tasks, though not
2554 IO tasks, but tasks anyway. Now fixed.
2556 * Defined SilcServerConnection structure to hold connection specific
2557 stuff about directly connected servers and routers. The definition
2558 is currently in silcd/server_internal.h. I thought about having
2559 a bit more important role fro this struct but for now it is used
2560 only when connecting to other server (or router actually).
2562 * Added connecting retry support in server when connecting to
2563 router(s). The retry feature implement exponential backoff
2564 algorithm. Also, added SilcServerParams structure to hold default
2565 parameters for server. For now, it include these retry settings
2566 and are hard coded. After server is moded to be as Silc Server
2567 Library this structure will be more important.
2569 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Changed client librarys channel->clients table to SilcList and
2572 changed code accordingly.
2574 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Changed client's channel table to SilcList and changed code
2577 accordingly. Also changed SilcChannelClientEntry to include back-
2578 pointer to the channel so that client entry can use that structure
2579 as list as well and we have fast cross-reference to the channel.
2580 This change dramatically decreased the complexity of channel
2581 handling with client entry and vice versa (removed one extra
2582 loop when searching for channel entry from many functions).
2584 * Changed server->sim from table to SilcDList and changed code
2587 * NAMES command can now be used from user interface. It will show
2588 the user list on the channel, neatly.
2590 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2591 Code now saves realname of the user if it becomes available.
2593 * Renamed configure.in to configure.in.pre and made ./prepare
2594 script to automatically add correct version string to
2595 configure.in which it creates from configure.in.pre.
2597 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * NAMES command reply now shows users mode with the nickname when
2602 * Moved silc_client_ch[u]mode[_char] functions from
2603 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2604 place sucks, they are utility functions and should be in some
2607 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2609 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2612 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Added TRQ (efficient deque and list library) into lib/trq. This is
2617 a very good list library that is currently used in the SILC. Defined
2618 SilcList API over the library because I didn't like the API very
2619 much. See lib/trq/silclist.h for the API and examples of how to
2620 use the API. Fixed various places in the code to use the new
2621 SilcList API. The SilcList is meant for lists that has a structure
2622 already defined as a list. It is not suitable to add just some
2623 context to the list (in TRQ, the context is the list actually).
2625 So, I defined SilcDList that can be used for the purpose where
2626 predefined list structure does not exit. This can be used as
2627 such list. Now some context just can be added to the SilcDList.
2628 Currently this list is not used in the SILC just yet, though there
2629 are a lot places where this can replace dynamically allocated
2630 tables and I will fix these places, later, to use SilcDList.
2631 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2632 and use TRQ internally).
2634 Also fixed some annoying warning messages that the original TRQ
2635 code generated. Also minor changes to TRQ's Makefile.in.
2637 * Added support for querying by Client ID to both WHOIS and
2638 IDENTIFY commands into server, as required by the protocol.
2640 * Removed method function pointers from SilcBuffer structure. They
2641 weren't used to anything and just increased the context size for
2642 no good reason. This change also made silc_buffer_alloc and
2643 silc_buffer_free functions inline functions.
2645 * Disabled command flooding detection support until it's fixed so
2646 that it accepts commands in but does not execute them more than once
2649 * Added silc_net_localhost(), to return local hostname, into
2650 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2651 that must be initialized before calling silc_client_init.
2653 * Added new function: silc_server_send_notify_on_channels to send
2654 notify messages to all channels client has joined. It is assured
2655 that the message is sent only once per client.
2657 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2658 lib/silcutil/silcutil.[ch] as silc_format function. The new
2659 function is generic and is used by server as well, not only by
2660 the logging routines.
2662 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2663 the provided version string was not acceptable. Added new function:
2664 silc_ske_check_version into lib/silcske/silcske.h. The function
2665 must be implemented by the application (client or server) and it
2666 does not reside in the SKE library. The function checks the version
2667 string remote end sent.
2669 * Added back pointers (to opaque context and to SilcSocketConnection)
2670 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2672 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2673 duplicate packet context structure.
2675 * Changed `notify' client operation to send same arguments as client
2676 receives from server except for ID's. ID's are mapped to correct
2677 ID entry and that is returned. Also, if channel entry is not sent
2678 by server but the notify is for channel the channel entry is sent
2679 to application (otherwise application doesn't know that it is for
2680 channel (library gets it from packet's Destination ID)).
2682 * Added silc_client_remove_from_channels into client library to
2683 remove a client from all channels it has joined to. Used when
2684 received SIGNOFF notify from server. Added also new function
2685 silc_client_replace_from_channels to replace old ID entry with
2686 new ID entry on all channels. Used when received NICK_CHANGE
2689 * Fixed ID Cache list handling in silc_idlist_get_client in
2690 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2691 to get (or query) client by ID.
2693 * Updated TODO list.
2695 * Added connection authentication status message defined by the
2696 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2697 support for these into the code in client and server side.
2699 * Added generic function silc_client_send_command to send any command
2700 with variable argument list. Application should use this function
2701 to send commands if the command functions provided by the library
2702 does not suite for the application's user interface needs.
2704 * Added new `failure' client operation. Application is notified about
2705 received failure packet if client is executing a protocol. In this
2706 case the protocol's execution has failed.
2708 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2709 is required by the protocol.
2711 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2712 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2715 * Added status flag to SilcSKE object to indicate realtime status
2716 of the SKE protocol.
2718 * Application receives now exactly same command reply arguments as
2719 the library receives from server. However, if ID is received the
2720 corresponding ID entry is returned to the application (eg. Client
2721 ID is mapped to correct SilcClientEntry entry and that is returned).
2722 Changed command_reply client operation due to this change.
2724 * Changed all ID's in commands and in command replys as ID Payloads.
2725 Change affected both client and server side codes.
2727 All ID's sent in SILC network (with execption of ID's in SILC
2728 Packet header) are sent in ID Payload to support variable length
2731 * Server now notifies nick changes and notifies all clients on
2732 the channels about the new nickname (about the new Client ID,
2735 * Implemented CMODE command to change channel modes. Supports all
2736 channel modes defined by the protocol specs except ban and invite
2737 lists. (Also, private channel key mode is supported but support for
2738 setting private channel key in client is missing, thus, this mode
2739 has no effect on client side (except that server requires that the
2740 client uses private channel key and normal channel traffic does not
2743 Also, invite mode works per se, but INVITE command does not work
2744 yet correctly, so you can set channel as invite only channel but
2745 inviting clients to the channel does not work (it is yet to be
2746 thought what's the best way to do it).
2748 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2749 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2750 Implemented CUMODE command to change user's mode on the channel.
2751 Supports all modes defined by the protocol specs.
2753 * Added NAMES command reply to return users modes on the channel.
2755 * Removed unnecessary and slow ciphers from lib/silccrypt.
2757 * Set SO_KEEPALIVE option to connection sockets by default.
2759 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2761 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2762 redefined the Notify Payload into protocol specs.
2764 * Added silc_id_payload_parse_id to get ID directly from raw
2767 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2770 accept searching by Client ID as well.
2772 * Added support for LEAVE and SIGNOFF notify types in client library.
2774 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2775 to parse ID Payload from raw data.
2777 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Added flags parameter into silc_ske_assemble_security_properties
2780 function in lib/silcske/silcske.[ch].
2782 * Changed notify client operation to fit better for notify messages
2783 sent by server. The notify payload received from server is now
2784 passed to the application (after parsing it to SilcNotifyPayload).
2785 It is application's responsibility to retrieve the arguments
2786 from the payload and show the message the way it wants. The message
2787 sent by server is implementation specific.
2789 * Changed public keys to comply with the protocol specification.
2790 Old public keys are not supported anymore and are not compatible.
2792 * Removed nickname from Channel Payload as the latest draft removed
2793 it. The client must resolve the nickname from the NAMES command
2794 reply received when it joined the channel.
2796 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2798 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Fixed some errors in protocol specification drafts.
2802 * Created lib/silccore/silcnotify.c to implement Notify Payload
2803 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2804 generic payloads described by protocol specifications. The file
2805 includes implementations for ID Payload and Argument Payload.
2807 * Changed Command Payload implementation to use the new Argument
2808 Payload. Changed command_xxxx_payload to command_payload_xxxx
2809 to comply with SILC coding conventions.
2811 * Added suppport for Argument Payload handling in Notify Payload
2812 implementation as protocol requires it. Added the new support
2813 into server and client lib as well.
2815 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Added support for multiple nicknames on same channel. [n] is
2818 added locally to the nickname if there are more than one same
2819 nicknames on the channel.
2821 * Server now sends all nicknames that matched WHOIS request.
2822 Client also shows the list received from server.
2824 * Added TOPIC command to client side. User can now set and show
2825 current topic on channel.
2827 * Added MOTD command to client and server. Also, server sends the
2828 motd when client connects to the server.
2830 * Changed version strings to comply ISO 8601.
2832 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Fixed protocol error handling in client library. It should now
2835 cope even if the SKE fails for some reason.
2837 * Made new protocol specification drafts for submitting to IETF.
2839 * Implemented TOPIC command to server in silcd/command.c.
2841 * Added two new notify types into lib/silccore/silcnotify.h:
2842 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2843 notify nickname change and topic setting/change on a channel.
2845 * API change of command_reply operation in client library. The
2846 application gets now the status type received from server as well.
2848 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2852 * Cras fixed and optimized the packet handling even further and
2853 it should work now. Minor change to the prototype of function
2854 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2856 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Added new function into lib/silcutil/silcschedule.[ch]:
2859 silc_schedule_with_fd to select() a specified fd. The function
2860 returns after timeout expires or data arrives or goes. The
2861 function is used by packet routines to wait that all data is
2862 received from network.
2864 * Fixed data reading from network in lib/silccore/silcpacket.c.
2865 The code now assures that all data is read from the fd and then
2866 continues packet processing. This was a bug fix since the code
2867 used to drop some data in some circumstances.
2869 * Added new function into lib/silcclient/client.[ch]:
2870 silc_client_start_key_exchange to start key exchange after
2871 connection has been established to server. The code internally
2872 now uses this funtion but its main purpose was to provide it
2873 for applications that perform their own connecting. After
2874 application has created a connection it merely calls this
2875 function to start the key exchange between client and server.
2876 The library takes care of everything else after that.
2878 Updated also lib/silcclient/README to explain the usage of
2881 * Do not send to application information that connection has
2882 been established. Application gets notified it by connect
2885 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Applied cras's patch to add silc_schedule_one function. The
2888 function runs scheduler once and returns.
2890 * Fixed the scheduler after cras messed it up. The timeout
2891 handling works now as it's supposed to work.
2893 * Added into lib/silccore/ silcnotify.h to include notify
2894 message types support. Changed silc_server_send_notify*
2895 functions, in server.[ch], to support those new notify types.
2896 Added the support for the notify types into client library,
2897 as well. Added new notify client operation into ops.h in
2900 * Changed silc_server_packet_send_to_channel to send normal
2901 packets instead of just channel message packets. The function
2902 is now used to send the notify packets to channels. It is not
2903 used to send channel message packets anymore, as server never
2906 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2907 va_arg()s as it seems to require it nowadays. I guess, if SILC
2908 is compiled with older va_arg() the new code should work anyway.
2910 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Splitted core library. Core library (lib/silccore) includes
2913 now only SILC protocol specific core (and common) components.
2914 Created new utility library (lib/silcutil) that includes more
2915 generic purpose stuff. The stuff for util library was taken
2916 from the old core library. This was minor and easy split.
2918 * Created SILC Client Library (lib/silcclient) that includes
2919 implementation of the SILC client without user interface. This
2920 was major move from silc/ directory. The code has been changed
2921 so that it is transparent towards the user interface. The
2922 silc/ directory includes now the same user interface as before
2923 and it uses the new client library. Read lib/silcclient/README.
2924 Basicly, the client library performs everything else related
2925 to SILC except user interface handling. Also, configuration
2926 files are considered to be part of user interface and library
2927 does not handle them.
2929 This change also changed a lot of structures, function naming etc.
2930 Most important change was that SilcClientWindow object was
2931 renamed to SilcClientConnection in the client library. Created
2932 also new file lib/silcclient/ops.h. Also added new files
2933 silc/local_command.[ch] and silc/client_ops.[ch].
2935 All these changes were made to make it easier for user interface
2936 designers to create what ever user interface for the SILC client
2939 It is also expected that the server will be moved to lib
2940 directory as well and SILC Server Library will be created;
2941 sometimes in the future.
2943 * Removed Local commands from lib/silccore/silccommand.h as
2944 they are application specific and new client library does not
2945 handle any of those anymore.
2947 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2948 old client implementation in silc/.
2950 * Added support for callback functions in SILC_LOG_* macros.
2951 Application can now set its own callbacks that will be called
2952 instead of using the default functions that will always print
2953 the debug messages to stderr (or stdout). Also, debugging can
2954 now be disabled by setting silc_debug to FALSE and re-enabled by
2955 setting it to TRUE. Note, that logging will still work even
2956 if debugging is disabled.
2958 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2959 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2960 silc_log_reset_debug_callbacks.
2962 * To enable debugging in silc client one must give now -d
2963 option on command line.
2965 * Changed silc_schedule_init to automatically allocate task queues
2966 if they are not allocated before calling it.
2968 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Added GMP 3.1 into math library.
2972 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2975 a channel in SILC network. The packet is used by servers and
2976 routers to notify other routers that user has left a channel.
2977 This little feature was missing until now. Added the feature
2978 to protocol specification as well.
2980 Added functions: silc_server_send_remove_channel_user and
2981 silc_server_remove_channel_user into server.[ch].
2983 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2984 lib/silccore/silcpacket.h. However, they are not implemented
2987 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Fixed joining to a channel and sending channel messages
2990 between server and router. The channel message sending should
2991 now work inside a cell.
2993 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Fixed the private message sending between server and router.
2996 The private message sending should now work inside a cell.
2998 * Added silc_server_replace_id into server.[ch] to replace
2999 existing ID in the SILC network.
3001 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3002 and silc_idlist_replace_server_id into idlist.[ch] in server.
3004 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Fixed the server to server connections. Server can again now
3007 connect to router. Router to router connections probably does
3010 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Added dynamic protocol registering support. Now protocols can
3013 registered and unregistered on the fly. Patch by cras.
3015 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Added lib/contrib directory to hold routines that some platforms
3018 don't have but are needed by SILC.
3020 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3021 into lin/contrib to provide getopt() and getopt_long() for
3022 those who don't have it.
3024 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Added AWAY command to client. When away message is set and
3027 client receives a private message packet the client automatically
3028 replies to the sender with the away message.
3030 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3031 bug seemed to be the cause of recent problems when compiling
3034 * Added version detection support to SKE protocol specification
3035 and added the new changes to the SKE implementation as well.
3036 There were other minor changes in the SKE protocol as well.
3038 Many changes in lib/silcske/silcske.[ch] and in
3039 lib/silcske/payload.[ch].
3041 * Added ^U functionality, clear input line. Patch from cras.
3043 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Mainly small bugfixes on core library. Fixed some debugging
3046 logging and buffer overflow in silclog.c.
3048 * Updated config.sub and config.guess on the distribution tree.
3050 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Added command lagging support in server. Client may execute
3053 commands now only once in two seconds.
3055 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Optimized packet reception. MAC computation and checking is now
3058 also more optimized. A lot previously duplicated code is now
3059 used as generic by both client and server.
3061 * Fixed key pair generation in clientutil.c
3063 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added into lib/silccore/silcbufutil.[ch] new function;
3066 silc_buffer_realloc.
3068 * Moved generic packet sending/encryption functions to
3069 lib/silccore/silcpacket.[ch] from client and server. Some
3070 rewriting of the functions.
3072 * Moved all generic packet reception/decryption functions to
3073 lib/silccore/silcpacket.[ch] from client and server. The
3074 packet processing is now much cleaner in both client and server.
3075 These were major changes in both client and server.
3077 * Created many common functions in server to do packet sending.
3078 Previously code were duplicated a lot, this has been removed
3081 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Rewrote major parts of the ID cache system. Don't know
3084 whether it is better now or not but at least the API is more
3087 * Major rewrite on ID cache stuff on client because of the ID
3088 cache API changes. Added idlist.c to client.
3090 * Also major rewrite on ID cache stuff on server as well.
3091 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3092 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3093 in hand, instead they are all put into the ID cache system now.
3094 All server_idlist_* routines uses ID cache now instead of
3095 traversing its own lists (those lists does not exist anymore).
3096 SilcIDList though still exists. Also, SilcXXXEntry's are
3099 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Finally made the SKE implementation compliant to the protocol
3102 specification. All mp integers are now binary encoded as
3103 opposed being HEX encoded.
3105 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3108 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3109 functions: silc_[encode/decode]_pem. Also added function
3110 silc_encode_pem_file to PEM encode with newlines ('\n') for
3113 * SILC public keys are now encoded either PEM or binary. Same
3114 option is for private keys as well. By default private keys
3115 are binary encoded and public keys PEM encoded. Silly HEX
3116 encoding were removed.
3118 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3119 function to create fingerprints.
3121 * Fixed a bug in SHA1; does not change the original data anymore.
3123 * Partly implemented INFO command on client and server side.
3124 Fixed CLEAR command. Changes to SERVER command; show current
3125 server(s) when giving command without arguments. Added
3126 VERSION command to client.
3128 * Added check to server that unregistered connections cannot
3129 execute commands (unless it is specificly allowed).
3131 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Fixed screen refresh.
3135 * Fixed channel joining bug from client. On some circumstances
3136 client tried to join to a channel it had already joined.
3138 * Added public key verification process into client's protocol.c.
3139 The client now verifies the public key from user and saves
3140 it into ~./silc/serverkeys/ directory.
3142 Added into: clientutil.[ch]: silc_client_verify_server_key.
3144 * Changed SKE protocol's silc_ske_initiator_finish function
3145 to accept callback function that verifies the received public
3146 key. Removed old silc_ske_verify_public_key function.
3148 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3151 silc_pkcs_private_key[_data]_set.
3153 * Made the password and public authentication more cleaner in
3154 server's protocol.c.
3156 * Removed historic and obsolete protocol `channel_auth' from
3157 both client and server.
3159 * Removed wrong way of sending command status messages from
3160 server to client in server's command.c. The old way violated
3161 protocol specification.
3163 Changes to silccore/silccommand.[ch]: removed
3164 silc_command_encode_status_payload -> not needed anymore,
3165 changed silc_command_encode_payload_va to accept extra
3166 argument on variable argument list. The argument type must
3167 now be provided to the function. Also, added new function:
3168 silc_command_encode_reply_payload_va which is same as
3169 normal command_encode_payload_va except command status type
3170 is provided as extra argument.
3172 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Added ~./silc directory handling. The directory includes the
3175 public and private keys for the client.
3177 Added silc_client_check_silc_dir, silc_client_create_identifier
3178 and silc_client_load_keys.
3180 * Implemented SILC protocol compliant public key. Added public
3181 and private key saving to and loading from files.
3183 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3184 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3185 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3186 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3187 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3189 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3190 silc_pkcs_load_[public/private]_key.
3192 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added silc_server_get_route (route.[ch]) to get connection
3195 data for the fastest route for given ID.
3197 * Implemented INVITE command on client and server. The command
3198 were re-defined in the SILC Protocol Specification and the
3199 implementation now complies with the specification.
3201 * Implemented PING command on client and server.
3203 * Implemented NAMES command on client and server. The server side
3204 supports currently only normal server not router server yet.
3205 Some changes to NAMES definition in SILC protocol specification.
3207 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Implemented LEAVE command on client and server.
3211 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3212 again. This change was made to the protocol as well. Server
3213 should not violate the protocol specification anymore.
3215 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3218 was tested. SOCKS4 was not but should work anyway.
