3 * Fixed the [AdminConnection] server config section to support
4 multiple entries. Affected file silcd/serverconfig.c.
6 * Added support into the server to check the validity of the
7 incoming connection before executing any KE or authentication
10 * The connection configuration is now saved to the KE and
11 connection auth protocol contexts and not fetched anymore in
12 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
14 * The local hosts listenning address and port is also resolved
15 now when starting the server. We want to have the socket object
16 to include the real address and port for the listener. Added
17 new function silc_net_check_local_by_sock into the files
18 lib/silcutil/silcnet.[ch].
20 * Fixed a broadcast bug in server -> do not broadcast if we
23 * Fixed a routing bug. Do not route broadcast packets ever.
24 Broadcast packets must be processed always and not routed since
25 they may be destined to some other host than yourself and thus
26 would get routed without no good reason. Affected file is
29 * Added function silc_server_config_is_primary_route to check
30 whether primary router connection has been configured (a router
31 configuration that we are initiating). If there is not, we
32 will assume that there is only two routers in the SILC network
33 and we will use the incoming router connection as our primary
34 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
36 * Changed the order of the broadcasting. Broadcast _after_ the
37 packet has been processed not before. Affected file is
40 * Fixed a [ClientConnection] parsing bug. The port was never
41 parsed correctly thus resulting to port 0. Affected file
44 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
45 argument and did not set the broadcast packet flag. Affected
46 file silcd/packet_send.c. Fixed same bug in the function
47 silc_server_send_notify as well.
49 * If we receive NEW_ID packet for our own ID in the server, ignore
52 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Removed the nickname from the Private Message Payload.
57 Updated the code and the protocol specs.
59 * Updated protocol specs for submitting to the IETF.
61 * Tweaked the Random Number Generator a bit. Affected file
62 lib/silccrypt/silcrng.c. Exported a new function
63 silc_rng_[global]_add_noise which can be used to add more
66 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Do not parse packets with different timeout when protocol
69 is active -> may cause problem with rekey. Affected file
72 * When server receives signoff notify it must not create
73 new channel key if the client is on any channels since the
74 sender of the signoff notify will create it.
76 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
78 * Added printing of error messages during SKE protocol from the
79 failure packet sent by server during SKE. Affected file
82 * Removed the client's failure_callback handling with timeout
83 and handle it immediately when received.
85 * The SKE library returned wrong type in SUCCESS and FAILURE
86 packets. They must be 32 bit MSB not 16 bit MSB.
88 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Ok, rewrote the logic of the re-key and now it seems to work.
91 I tested it on high traffic with frequent re-keys without
92 problems. Added hmac_receive (and renamed hmac to hmac_send)
93 in SilcClientConnection in lib/silcclient/client.h and
94 in SilcIDListData in silcd/idlist.h. Also, removed the
95 SilcPacketParserContext's cipher and hmac fields as they are
96 not needed anymore and actually caused some problems when
97 the ciphers and hmac's changed underneath the packet parser.
99 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * If re-key protocol is active then process the incoming packets
102 synchronously since we must assure that icoming packets encrypted
103 with the old key is processed before the new keys is set to
104 use. This is true other packets than for REKEY packets.
105 Affected file silcd/server.c. The same was done to client library
106 as well, affected file lib/silcclient/client.c.
108 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Fixed bug in client and server to accept the force send if
111 the packet is send from silc_[server/client]_packet_process
112 function. Otherwise the packets are never delivered, oops.
114 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Disable force sending of packets when REKEY protocol is active.
117 We must assure that no packet is sent directly when rekey is
118 performed. All packets must be sent through packet queue.
119 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
120 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
121 function is silc_[server/client]_packet_send_real to check
124 * Replaced the SIM paths from example config files to
125 /usr/local/modules. Also, make install creates now
126 /usr/local/silc/logs directory to hold all the SILC server
129 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Made the configure.in.pre work on Solaris. Patch by salo.
133 * Made all ciphers compatible with non-x86 machines. Defined
134 CBC mode macros into lib/silccrypt/ciphers_def.h.
136 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Fixed the make install.
140 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * When MAC computation fails the silc_packet_decrypt returned 0
143 even though it was supposed to return -1. Fixed this. The
144 affected file is lib/silccore/silcpacket.c.
146 * Do not replace the config files in /etc/silc (in make install)
147 if they already exist. Affected file ./Makefile.am.
149 * Do not send re-key packets immediately but through packet queue.
150 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
152 * Changed silc_net_check_host_by_sock to return FALSE if the
153 IP/DNS could not be resolved. Though, it returns the IP address
154 now even if it could not resolve it (but returns also FALSE).
155 Affected file lib/silcutil/silcnet.[ch].
157 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Added silc_pkcs_decode_identifier to decode the public key's
160 identifier. Affected file lib/silccrypt/silpkcs.[ch].
161 Added also silc_pkcs_free_identifier. Added also new context
162 SilcPublicKeyIdentifier.
164 * Added -S option to the silc client. It is used to dump the
165 contents of the specified public key file.
167 * Changed the PKCS api to return the public key length when
168 setting the public key.
170 * Fixed a fatal bug in the public and private key file loading.
171 Affected file lib/silccrypt/silcpkcs.c.
173 * Execute the packet parsing for client with zero (0) timeout
174 if the protocol is active. Affected file silcd/server.c.
176 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Made the key generation options to the silcd program. Added
179 -C option, equivalent to client's option.
181 * Added new [ServerKeys] config section to the server. It
182 configures the server's public and private key.
184 * Defined generic Public Key Payload into the protocol
185 specification to send specific type of public keys and
188 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
189 public key or certificate.
191 * Implemented the GETKEY command to the server and to the
192 client library and on user interface.
194 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Made preliminary `make install' work.
198 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
200 * Added SilcServerRekey context into silcd/idlist.h.
202 * Added the PFS support as defined in the specification to the
203 SKE protocol. Affected files lib/silcske/*.c.
205 * Added `ske_group' field to the SilcServerRekey context to hold
206 the number of the SKE group that is used with PFS in re-key.
207 Affected file silcd/idlist.h.
209 * Added PFS re-key support to the server. Affected file is
212 * Added silc_protocol_cancel to cancel execution of the next
213 state of the protocol. Affected file is
214 lib/silccore/silcprotocol.[ch].
216 * Added the re-key support with and without PFS to the client
217 library. Re-key is performed once in an hour, by default.
219 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
220 Added silc_client_rekey_callback and silc_client_rekey_final.
221 Affected files are lib/silcclient/protocol.[ch] and
222 lib/silcclient/client.[ch].
224 * Removed the `hmac_key' and `hmac_key_len' fields from the
225 SilcClientConnection structure; not needed. Affected file is
226 lib/silcclient/client.h.
230 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
232 * Do not ask whether user wants to use the negotiated private key
233 for private messages, just use it. Affected file is
234 silc/local_command.c.
236 * Added `send_enc_key' and `enc_key_len' fields to the
237 SilcIDListData structure since they are needed in the re-key
238 phase. Affected file is silcd/idlist.[ch].
240 * Implemented the simple re-key protocol into the server.
241 Affected files silcd/server.c and silcd/protocol.[ch]. The
242 re-key will be performed once in an hour, by default.
244 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
245 Added silc_server_rekey, silc_server_rekey_callback and
246 silc_server_rekey_final.
248 * Removed Tunneled flag from the protocol. Updated the code
249 and the specifications.
251 * Adde `pfs' field to the SilcIDListData to indicate whether
252 the PFS is to be performed in the re-key. Affected file is
255 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
258 int64 of at least the xintXX size. If void * is less that 4
259 bytes uint32 * will be used. Defined bool as boolean.
261 * Changed _ALL_ unsigned long and unsigned int to uint32,
262 unsgined short to uint16 in the source tree.
264 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
265 not handle clients that has entry->data.registered == FALSE.
266 They are not in the network anymore. Affected file is
269 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Implemented the sending of the SERVER_SIGNOFF notify in the
272 server. Affected file is silcd/server.c.
274 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
275 Added also silc_notify_payload_encode_args into the
276 lib/silccore/silcnotify.[ch].
278 * Implemented ther SERVER_SIGNOFF notify handling in the server.
279 Affected file silcd/packet_receive.c.
281 * Implemented the SERVER_SIGNOFF notify handling in the client
282 library. Affected file lib/silcclient/client_notify.c. Also,
283 implemnted the printing of the SERVER_SIGNOFF info to the
284 application. Affected file silc/client_ops.c.
286 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
287 if the deleting was successful. Affected file silcd/idlist.[ch].
289 * Added support for public key authentication in the connection
290 authentication protocol in the client library. Affected file
291 lib/silcclient/protocol.c.
293 * Changed the server's silc_idlist_get_clients_by_* interface
294 to support already allocated array so that new entries may be
295 added to pre-allocated array. Affected file silcd/idlist.[ch].
296 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
299 * All command reply functions in the server now calls the
300 pending command callback even if error occured. This way the
301 error will be delivered to the client as well. Affected files
302 silcd/command.c and silcd/command_reply.c.
304 * Fixed INFO command to return local server's info if no server
305 was provided. Affected file lib/silcclient/command.c.
307 * Removed RESTART command for good. Updated the code and the
310 * Rewrote parts of the task system. It is a bit simpler now.
311 Removed unsued task priorities. The affected files are
312 lib/silcutil/silctask.[ch].
314 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
316 * Moved the USERS printing from the library to the application.
317 Affected files lib/silcclient/command.c and silc/client_ops.c.
319 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Added channel key re-key support. The re-key is perfomed
324 only by the router and is done once in an hour. Added `rekey'
325 field to the SilcChannelEntry in the server. Affected files
326 silcd/server.c and silcd/idlist.h.
328 * Added silc_task_unregister_by_context into the file
329 lib/silcutil/silctask.[ch].
331 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Added SILC_UMODE_GONE mode to indicate when the client is not
334 present in the SILC network. Added also support to the local
335 command AWAY that will set this mode. Added support of showing
336 "xxx is gone" in WHOIS command. The USERS command shows the
339 * Fixed setting server and router operator privileges in the
340 server's UMODE command. Affected file silcd/command.c.
342 * Merged the SKE KE1 and KE2 payloads into one payload. The
343 new KE payload is equivalent to the old KE2 payload.
345 Cleaned up the SKE Start Payload parsing. It now uses the
346 simple buffer unformatting to do the parsing. A lot faster
349 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
350 to the SKE that is used to indicate whether both of the SKE
351 parties should perform authentication. By default only the
352 responder performs authentication. By setting this flag also
353 the initiator must do authentication. By default it is unset
354 since in normal SKE case, client to server connection, only
355 the responder should do authentication. When doing SKE between
356 two clients both should perform authentication. Updated the
357 code and the protocol specs.
359 * A little fix to IDENTIFY command in the server. Search the
360 client first by hash not nickname. Affected file is
363 * Fixed the silc_client_close_connection to support closing
364 the client to client connections wihtout deleting too much
365 data. Affected file lib/silcclient/client.c.
367 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
368 are received if protocol used to be active but is not anymore
369 the application would crash due to NULL pointer dereference.
370 Affected files silcd/server.c and lib/silcclient/client.c.
372 * Added `hash' field to the SilcClientConnection to include
373 the hash function negotiated in the SKE protocol.
375 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
376 to set the channel founder authentication data. A client can
377 claim the founder rights later by providing the authentication
378 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
379 This way the channel founder can regain the channel founder
380 privileges even it is left the channel. This works only on
381 local server and the client must be connected to the same
382 server to be able to regain the founder rights. Updated the
383 protocol specs accordingly.
385 Added support to the CMODE command in the client to set the
386 founder auth data. Read the README to see how to set it.
388 Added support to the CUMODE command to claim the founder
389 rights. Read the README to see how to do it.
391 Added support for the founder authentication to the Channel
392 Entry in the server. Affected file silcd/idlist.h.
394 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
395 server's CMODE command. Affected file silcd/command.c.
397 * Added the following new functions into lib/silccore/silcauth.[ch]:
398 silc_auth_get_method and silc_auth_get_data.
400 * The server now saves the remote hosts public key to the
401 SilcIDListData pointer. Affected file silcd/protocol.c.
403 * The normal server now does not remove the channel entry from
404 the cache if the founder authentication data is set. It used
405 to remove it if the founder was the last one on the channel on
406 the server and left the channel. The auth data is saved and
407 if the channel is re-joined later the old entry is used with
408 the old auth data. Affected files silcd/command_reply.c and
411 * Removed the `pkcs' field from the SilcIDListData structure
412 in the server; it is not used. Affected file silcd/idlist.h.
414 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Fixed packet processing on slow links. Partial packets were
417 never re-processed because the incoming data buffer was cleared
418 by the application. Application must not directly clear the
419 sock->inbuf, the packet processing routines handle it. Fixed
420 this in client library and in server.
422 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Fixed the WHOIS and IDENTIFY send reply function to really
425 check whether to send list or just one entry. Affected file
428 * Cleaned up the LEAVE command's channel key distribution. The
429 affected file silcd/command.c.
431 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
432 can enforce the channel mode as well. In that case the ID
433 includes the ID of the server. The code now enforces the
434 mode change if the router have different mode than the server.
436 * The notify client operation with CMODE_CHANGE notify can now
437 return NULL client_entry pointer if the CMODE was not changed
438 by client. Application must check for this.
440 * Added <Server ID> argument to INFO command to support server
441 info fetching by Server ID.
443 * Added silc_server_announce_get_channel_users to get assembled
444 packets of channel users of the specified channel. Affected
445 file silcd/server.[ch].
447 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
448 was freed underneath the ID Cache.
450 * Re-announce clients when the server received CHANNEL_CHANGE
451 notify from the router. Affected file silcd/packet_send.c.
453 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
456 crashed since it did not handle the fact that there is no cipher
457 called "3" and didn't check the error condition. Now fixed.
459 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
460 flag. It can be used to send message requests.
462 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Implemented the RESTART command in the client.
466 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
467 notice type messages. Added notice printing to the user
470 * The channel keys are not re-generated if the channel's mode
471 is PRIVKEY, ie private key on the channel exists. Affected
472 files silcd/server.c and silcd/command.c.
474 * Fixed a little bug in channel message delivery when channel
475 private keys are set in the server. Affected file is
478 * Changed the setting on channel->on_channel = TRUE from the
479 silc_client_save_channel_key to the JOIN command reply. The
480 key payload is not received if the private channel key is set.
481 Affected file lib/silcclient/command_reply.c and the
482 lib/silcclient/client_channel.c.
484 * When the CMODE_CHANGE notify is sent and the channel private
485 key mode is removed the channel key must be re-generated in
486 other cells as well. Added this support for the router in the
487 silcd/packet_receive.c.
489 * Added new local command NOTICE to send notice message on
490 channel. Affected file silc/local_command.[ch].
492 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Added new local command ME to the client. It is used to send
495 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
496 some action. Affected file silc/local_command.[ch].
498 * Changed channel_message and private_message client operations
499 to deliver the message flags to the application. Added also
500 the `flags' arguments to the silc_client_send_channel_message
501 and silc_client_send_private_message functions. Affected file
504 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Redefined the Private Message Payload to support private message
507 keys and to support the new private message flags. Updated
508 the protocol specs. Flags makes it possible to have for example
511 * Added new type SilcPrivateMessagePayload and defined an API
512 for it in the lib/silcclient/silcprivate.[ch].
514 * Tested private message private keys successfully. Tested the
515 private message key set, unset and list commands with the new
518 * Redefined the Channel Message Payload to include the channel
519 message flags (equal with private message flags) to support
520 for example CTCP style messages.
522 * Defined some of the message (for channel and private message)
523 flags. Updated the protocol specs and added the flags to the
524 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
526 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Added SilcKeyAgreementStatus type to the key agreement routines
529 to indicate the current status and error if one occured.
530 The status types are defined in the lib/silcclient/silcapi.h.
532 * Added new local command KEY that is used to set and unset private
533 keys for channels, set and unset private keys for private messages
534 with remote clients and to send key agreement requests and
535 negotiate the key agreement protocol with remote client. The
536 key agreement is supported only to negotiate private message keys,
537 it currently cannot be used to negotiate private keys for channels,
538 as it is not convenient for that purpose.
540 * Fixed a minor pending callback setting bug in the function
541 silc_client_get_client_by_id_resolve, now the function works.
542 Affected file lib/silcclient/idlist.c.
544 * Added function silc_net_get_local_port to get local bound
545 port by socket. Added to lib/silcutil/silcnet.[ch].
547 * Added `sockets' and `sockets_count' fields to the SilcClient
548 object. They hold the sockets of the listenning sockets in
549 the client. Listenning sockets may be for example the key
550 agreement server. Affected file lib/silcclient/client.[ch].
551 Added functions the silc_client_add_socket and the
552 silc_client_del_socket. They are exported to the application
555 * Added ~./silc/clientkeys to support other client's public keys.
557 * Renamed verify_server_key client operation to verify_public_key
558 and added one argument to indicate the type of the connection
559 (server, client etc.).
561 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Added silc_server_connection_auth_request to handle the
564 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
565 silcd/packet_receive.[ch].
567 * Added silc_server_send_connection_auth_request into the
568 silcd/packet_send.c to send the connection auth request packet.
570 * Cleaned up the silcd/protocol.c a bit and fixed some memory
573 * Fixed the public key authentication in responder side in the
574 server. The `auth_data' pointer includes the SilcPublicKey
575 not the path to the public key. Affected file silcd/protocol.c.
577 * Implemented the public key authentication in the initiator side
578 in the server. Affected file silcd/protocol.c.
580 * Removed the [RedirectClient] config section from the server
581 configuration. Is not needed and I don't want to implement it.
583 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
585 * Cleaned up the CMODE command in the server. It now works
586 correctly and supports all the modes defined in the protocol.
587 Affected file is silcd/command.c.
589 * Added `hmac_name' field to the SilcChannelEntry in the server
590 to hold the default HMAC of the channel. It can be set when
591 creating the channel (with JOIN command). Affected files
594 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
595 type to indicate the change of the current cipher and hmac
596 on the channel. Client can safely ignore the <cipher> argument
597 (if it chooses to do so) since the CHANNEL_KEY packet will
598 force the channel key change anyway. The <hmac> argument is
599 important since the client is responsible of setting the new
600 HMAC and the hmac key into use.
602 * Fixed the CMODE command in the client library as well.
604 * Tested CMODE command in router environment successfully.
606 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Show the version of the remote client (or server) when connecting
609 to the server. It is logged to the log file. Affected file
612 * Fixed the KILLED notify handling in the client library. The
613 client must be removed from all channels when receiving the
616 Also, do not remove the client entry when giving the KILL
617 command but when the KILLED notify is received.
619 * Removed silc_idlist_find_client_by_nickname from the server.
620 Not needed anymore. Affected files silcd/idlist.[ch].
622 * Implemented the CHANNEL_CHANGE notify type handling to the
623 server. Affected file silcd/server.c.
627 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Added silc_server_send_notify_invite to send the INVITE
630 notify between routers.
632 * Implemented the INVITE command correctly to the server.
634 * Implemented the INVITE notify type handling in the server.
636 * Implemented the INVITE command to the client library and on the
639 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Added function silc_server_get_client_resolve to find the
642 client entry by ID from all ID lists and then resolve it
643 (using WHOIS) if it cannot be found. Affected file is
646 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Implemented the BAN command to the client library.
650 * The JOIN command in the server now checks the invite list
653 * Changed the silc_command_reply_payload_encode_va and the
654 silc_command_payload_encode_va to support that if argument is
655 NULL it ignores and checks the next argument. Affected file
656 lib/silccore/silccommand.c.
658 * Added silc_server_send_notify_ban to send the BAN notify
659 type between routers.
661 * Chaned the silc_notify_payload_encode to support that if
662 argument is NULL it ignores and checks the next argument.
663 Affected file lib/silccore/silcnotify.c.
665 * Tested ban lists in router environment successfully.
667 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Implemented BAN command to the server, in silcd/command.[ch].
671 * Removed the BAN and INVITE_LIST modes from the CMODE command
674 * Added function silc_string_match to regex match two strings.
675 Affected files lib/silcutil/silcutil.[ch].
677 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Redefined parts of the SilcChannelEntry in the server to support
680 the new ban and invite lists.
682 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Redefined the INVITE command. The same command can be used to
685 invite individuals to the channel but also to manage the invite
686 list of the channel (to add to and remove from the invite list).
687 Updated the protocol specs.
689 * Added new command SILC_COMMAND_BAN that can be used to manage
690 the ban list of the channel. Updated the protocol specs.
692 * Removed the channel modes: the SILC_CMODE_BAN and the
693 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
694 in the CMODE command. The equivalent features are now available
695 using INVITE and BAN commands. Updated the protocol specs.
697 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
698 in the network about change in the current ban list. The notify
699 type is not used by the client.
701 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
702 support the invite lists.
704 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Added new function silc_string_regexify that converts string
707 including wildcard characters into regex string that can
708 be used by the GNU regex library. Added into the file
709 lib/silcutil/silcutil.[ch].
711 Added silc_string_regex_combine to combine to regex strings
712 into one so that they can be used as one regex string by
713 the GNU regex library. Added into the file
714 lib/silcutil/silcutil.[ch].
716 Added silc_string_regex_match to match two strings. It returns
717 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
719 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Imported GNU regex to the soruce tree into lib/contrib.
722 Fixed some compiler warning from the regex.c.
724 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Fixed MOTD command in the server to work in router environment.
728 * Fixed the MOTD command in the client library to support
729 the server argument in the command.
731 * Added `nickname_len' argument to the silc_idlist_add_client
732 in the server, as the `nickname' argument may be binary data
735 * Added silc_idlist_get_channels to return all channels from
738 * Implemented LIST command to the server. Affected file is
741 * Implemented the LIST command to the client library and on the
744 * Added [<user count>] argument to the LIST command reply.
745 With private channels the user count is not shown.
747 * Updated TODO and README.
749 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * The client entry's data.registered must be TRUE even with
752 global client entry on global client list. The data.registered
753 is used to check whether the client is anymore in the network,
754 for example with WHOWAS command so it must be valid.
756 * Fixed the WHOWAS command in the server. It now actually works
757 in router environment. Added function into silcd/command_reply.c
758 silc_server_command_reply_whowas_save.
760 * Added silc_idlist_purge function to the silcd/idlist.c
761 to periodically purge the ID Cache.
763 * Fixed INFO command in the server. It works now in router
764 environment. Added <server name> argument to the INFO command
765 reply. Updated the protocol specs.
767 * Fixed minor bug in silc_idcache_purge to not purge if the
768 expire value is zero.
770 * Fixed various bugs in WHOIS and IDENTIFY command handling as
771 they were buggy because of the WHOWAS information.
773 * Fixed local command MSG to handle the async resolving of
774 the remote client properly. It used to fail the first MSG.
775 Affected file silc/local_command.c.
777 * Added `data_len' field to SilcIDCache context.
779 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Update TODO. Todo in commands in the server.
783 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
786 used by routers as broadcast packet to inform other routers
787 about the changed user mode.
789 Implemented the notify handling in the server. Affected file is
790 silcd/packet_receive.c. Added the function
791 silc_server_send_notify_umode to the silcd/packet_send.[ch].
793 * Added new generic Channel Payload and deprecated the New Channel
794 Payload. The New Channel Payload is now the generic Channel
797 * Added new argument `mode' to the silc_server_send_new_channel
798 as it is required in the Channel Payload now.
800 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
801 and created a new and real SilChannelPayload to represent the
802 new generic Channel Payload. Implemented the encode/decode
803 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
805 * Added silc_server_get_client_channel_list to return the list
806 of channels the client has joined for WHOIS command reply.
807 Affected file silcd/server.[ch].
809 * Implemented the channel list sending in the WHOIS command reply
810 in server and in the client.
812 Implemented the channel list displaying on the user interface
813 as well. Affected file silc/client_ops.c.
815 * Added silc_channel_payload_parse_list to parse list of Channel
816 Payloads. It returns SilcDList list of SilcChannelPayloads.
817 Client for example can use this function to parse the list of
818 channels it receives in the WHOIS command reply. The caller
819 must free the list by calling silc_channel_payload_list_free.
820 Affected files lib/silccore/silcchannel.[ch].
822 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Added one new argument <user mode> to the WHOIS command reply
825 to return the mode of the user in SILC. Updated the protocol
828 Implemented it to the server and client.
830 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Fixed the mode printing on the user interface on joining.
833 Affected file silc/client_ops.c.
835 * Implemented the UMODE command and user modes in general to the
836 client library and to the user interface.
838 * Implemented the UMODE command to the server.
840 * The server now sends UNKNOWN_COMMAND error status if client sends
841 unknown command. Affected file silcd/command.c.
843 * All server commands now handle the command identifier the right
844 way when sending the command reply to the client. The client can
845 use to identify the command replies with the identifier.
847 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Added silc_server_get_client_route to resolve the route to
850 the client indicated by the client ID. Affected file is
853 * Added silc_server_relay_packet as general function to relay
854 packet to arbitrary destination. This deprecates functions
855 like _send_private_message_key, _relay_notify etc. Affected
856 file is silcd/packet_send.[ch].
858 Removed silc_server_send_key_agreement,
859 silc_server_send_private_message_key and
860 silc_server_packet_relay_notify functions from the file
861 silcd/packet_send.[ch].
865 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
866 server. Affected file silcd/packet_receive.[ch].
868 * Implemented the KILL command to the client. Implemented the
869 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
870 Affected files lib/silcclient/command[_reply].c and
871 lib/silcclient/client_notify.c. Implemented the KILL notify
872 printing in the user inteface.
874 * Fixed a lot silc_parse_nick memory leaks from the client
875 library in the file lib/silcclient/command.c.
877 * Changed the silc_server_send_notify_on_channels's `sender'
878 argument from SilcSocketConnection to SilcClientEntry to
879 check the sender as entry and not as connection object and not
880 to send to the client provided as argument. The affected file
881 is silcd/packet_send.[ch].
883 * The notify packets that are destined directly to the client used
884 to not to be processed by the server. Now changed that and the
885 server processes all notify packets. After relaying the packet
886 to the client the notify packet is processed in the server.
888 * The silc_server_free_client_data now checks whether there is
889 pending outgoing traffic for the client and purges the data to
890 the network before removing the client entry.
892 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
895 an client is killed from the SILC Network. Updated the protocol
898 Added new function silc_server_send_notify_killed to the
899 silcd/packet_send.[ch].
901 * Added function silc_server_packet_relay_notify to relay notify
902 packets that are destined directly to a client. In this case
903 the server does not process the notify packets but merely relays
904 it to the client. Affected file silcd/packet_send.[ch].
906 Added also silc_server_packet_process_relay_notify to check
907 whereto relay the notify. Affected file is
908 silcd/packet_receive.[ch].
910 * Implemented the KILL command to the server.
914 * Added the backup schema desgined last fall to the protocol
915 specs for everyone to see. The specification is in the
916 *-spec-xx.txt draft and the packet type definitions for the
917 backup routers is in *-pp-xx.txt draft. Thusly, added also
918 new packet type SILC_PACKET_CELL_ROUTERS.
920 * A big security problem in the implementation discovered. The
921 signoff of an client did not cause new channel key generation
922 which it of course should've done. The channel keys must be
923 always re-generated when client leaves (or signoffs) the channel.
924 The silc_server_remove_from_channels funtion now handles
925 the channel key re-generation.
927 * Added `sender' argument to the silc_server_send_notify_on_channels
928 to not to send the client provided as argument. Affected file
929 silcd/packet_send.[ch].
931 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Implemented OPER and SILCOPER commands into the server and
936 * Added silc_auth_verify and silc_auth_verify_data to verify
937 the authentication directly from the authentication payload.
938 It supports verifying both passphrase and public key based
939 authentication. Affected file lib/silccore/silcauth.[ch].
941 * Added `hash' field to the SilcIDListData structure. It is the
942 hash negotiated in the SKE protocol. Affected file is
945 * Slight redesigning of the SilcAuthPayload handling routines.
946 Do not send SilcPKCS but SilcPublicKey as argument.
948 * Implemented the public key authentication support to the
949 serverconfig. The public key is loaded from the provided path
950 and saved as authentication data to void * pointer. Thus,
951 changed the unsigned char *auth_data to void *auth_data;
953 * Fixed SHUTDOWN command to send the reply before the server
954 is shutdown. :) Affected file silcd/command.c.
956 * Fixed fatal bug in CONNECT command. The hostname was invalid
957 memory and server crashed. Affected file silcd/command.c.
959 * Fixed fatal bug in CLOSE command. The server_entry became
960 invalid but was referenced later in the command. Affected file
963 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Fixed fatal bug in failure packet handling. Server ignored
966 the failure and thus crashed when it came.
970 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
973 that the command may be executed only once in (about) 2 seconds.
974 The old SILC_CF_LAG flag is same but allows command bursts up
975 to five before limiting.
977 Added the support for CF_LAG and CF_LAG_STRICT flags to the
978 server code. Various commands now includes the CF_LAG_STRICT
979 flag to disallow any kind of miss-use of the command.
981 * Fixed the silc_buffer_unformat to not to allocate any data
982 if the length of the data is zero. It used to allocate the
983 length + 1. Affected file lib/silcutil/silcbuffmt.c.
985 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Changed the format of AdminConnection configuration section
988 in the server. Added username of the admin to the format.
989 Affected files silcd/serverconfig.[ch].
991 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
992 to return admin configuration data by host, username and/or
995 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Implemented WHOWAS command to the server. Added the functions:
999 silc_server_command_whowas_parse,
1000 silc_server_command_whowas_send_reply,
1001 silc_server_command_whowas_from_client and
1002 silc_server_command_whowas_from_server
1004 * Added <Client ID> argument to the WHOWAS command reply. Updated
1005 the protocol specs accordingly.
1007 * Implemented WHOWAS command and command_reply to the client
1010 Implemented the WHOWAS printing on the user interface.
1012 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Added new argument to the WHOWAS command reply, the real name.
1015 It is an optional argument. Updated the protocol specs.
1017 * Added SilcIDCacheDestructor callback that is registered when
1018 the SilcIDCache is allocated. The callback is called when
1019 an cache entry in the ID Cache expires, or is purged from the
1020 cache. Added into lib/silccore/idcache.[ch].
1022 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1023 to destruct the client entries when the cache entry expires.
1024 Other ID Cache's in server and in the client library ignores
1027 * If the ID Cache entry's `expire' field is zero then the entry
1028 never expires. Added boolean `expire' argument to the
1029 silc_idcache_add function in the lib/silccore/idcache.[ch].
1030 If it is TRUE the default expiry value is used.
1032 * Added silc_server_free_client_data_timeout that is registered
1033 when client disconnects. By default for 5 minutes we preserve
1034 the client entry for history - for WHOWAS command.
1036 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Added support to the server to enforce that commands are not
1039 executed more than once in 2 seconds. If server receives
1040 commands from client more frequently, timeout is registered
1041 to process the commands. Affected file silcd/command.c.
1042 Added new function silc_server_command_process_timeout.
1044 * Changed NICK_NOTIFY handling in client library to check that
1045 if the client's nickname was changed, so there is no need to
1046 resolve anything from the server.
1048 * Removed error printing from the WHOIS and IDENTIFY commands.
1049 If error occurs then it is ignored silently in the client library.
1050 The application, however, may map the received error to
1051 human readable error string. The application currently maps
1052 the NO_SUCH_NICKNAME error to string.
1054 * Made the command status message public to the application. Moved
1055 them from lib/silcclient/command_reply.c to
1056 lib/silcclient/command_reply.h. The application can map the
1057 received command status to the string with the
1058 silc_client_command_status_message function.
1060 * Added check to the server to check that client's ID is same
1061 as the Source ID in the packet the client sent. They must
1064 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added dist-bzip hook to the Makefile.am to make bzip2
1067 compressed distributions.
1069 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Server now enforces the maximum length for the nickname and
1072 the channel as protocol specification dictates. 128 bytes for
1073 nickname and 256 bytes for channel name.
1075 * Moved the WHOIS printing to the application. The client libary
1076 does not print out the WHOIS information anymore, the application
1077 must do it. Renamed silc_client_command_reply_whois_print to
1078 the silc_client_command_reply_whois_save.
1080 The client's idle time is also sent to the application now, and
1081 the idle is shown on screen.
1083 * Added silc_client_command_reply_identify_save to save the
1084 received IDENTIFY entries.
1086 * Do not check for channel private keys in message sending and
1087 reception if the channel does not have the PRIVKEY mode set.
1088 Affected file lib/silclient/client_channel.c.
1090 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1092 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1093 just surfaced after chaning the JOIN procedure.
1095 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Added silc_client_get_clients_by_list to get client entries
1098 from Client ID list, that is returned for example by JOIN
1099 and USERS command replies. The application should use this
1100 function for example when JOIN command reply is received to
1101 resolve the clients already on the channel (library does not
1102 do that anymore as USERS command reply is not used in the JOIN
1103 procedure anymore). Affected files lib/silcclient/silcapi.h and
1104 lib/silcclient/idlist.c.
1106 * JOIN command reply and USERS command reply returns now SilcBuffer
1107 pointers instead of unsigned char pointers when returning
1108 the client list and mode list.
1110 * Added <Client ID> argument to the JOIN command reply, mainly
1111 for the server to identify for which client the command was
1112 originally sent. Updated protocol specs accordingly.
1114 * Added SilcDlist private_key pointer to the SilcChannelEntry
1115 in the client to support the channel private keys. Affected
1116 file is lib/silcclient/idlist.h.
1118 * Added SilcChannelPrivateKey argument to the function
1119 silc_client_send_channel_message so that application can choose
1120 to use specific private ke if it wants to. If it is not provided,
1121 the normal channel key is used, unless private keys are set.
1122 In this case the first (key that was added first) is used
1123 as the encryption key.
1125 * Implemented the support for channel private key handling.
1126 Implemented the following functions:
1128 silc_client_add_channel_private_key,
1129 silc_client_del_channel_private_keys,
1130 silc_client_del_channel_private_key,
1131 silc_client_list_channel_private_keys and
1132 silc_client_free_channel_private_keys
1134 Affected file lib/silcclient/client_channel.c.
1136 * Added the support for the private keys in the channel message
1137 sending and encryption and in the message reception and
1138 decryption. Affected funtions are
1139 silc_client_send_channel_message and silc_client_channel_message.
1141 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Added SKE's key verify callback to the client library's
1144 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1146 * Removed the statement that server (or router) must send USERS
1147 command reply when joining to the channel so that the client
1148 knows who are on the channel. Instead, the client list and
1149 client's mode list is now sent in the JOIN command reply to the
1150 client who joined channel. This is better solution.
1152 * Added function silc_server_get_users_on_channel and function
1153 silc_server_save_users_on_channel to the silcd/server.[ch].
1155 * Removed function silc_server_command_send_users from the
1158 * Do not show topic on the client library anymore. The topic is
1159 sent in the command reply notify to the application and the
1160 application must show the topic now.
1162 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Added client searching by nickname hash into the IDENTIFY and
1165 WHOIS commands in the server as they were clearly missing from
1166 them. Affected file is silcd/command.c.
1168 * Fixed a bug in private message receiving in the client library.
1169 The remote ID was freed and it wasn't supposed, now it is
1172 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Minor fix to the channel payload; allocate the data area, as it
1175 needs to be of specific length.
1177 * If the key agreement port is zero then the operating
1178 system will define the bound port. Affected files are
1179 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1181 * Added new function silc_channel_payload_decrypt into the file
1182 lib/silccore/silcchannel.[ch].
1184 * Moved the channel message etc, check from silc_packet_decrypt
1185 to applications. The library calls now a generic
1186 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1187 when the packet is either normal or special. This was done to
1188 allow more wide range of checking that was not allowed when
1189 the code was in library. Now applications can do virtually any
1190 checks to the packet and return to the library the decision how
1191 the packet should be processed. Affected files are
1192 lib/silccore/silcpacket.[ch].
1194 Added silc_server_packet_decrypt_check to the server and
1195 silc_client_packet_decrypt_check to the client library.
1197 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1198 to send with specified source and destination information.
1200 * Channel message delivery between routers was broken after the
1201 channel key distribution was fixed earlier. The channel key
1202 was used be to distributed to other routers as well which is not
1203 allowed by the protocol. Now this is fixed and channel keys
1204 really are cell specific and the channel message delivery between
1205 routers comply with the protocol specification.
1207 * Fixed various commands in server to check also the global list
1208 for the channel entry and not just the local list. The affected
1209 file silcd/command.c.
1211 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added assert()s to buffer formatting and unformatting routines
1214 to assert (if --enable-debug) when error occurs. Affected
1215 file: lib/silcutil/silcbuffmt.c.
1217 * Changed to auto-reconnect to check whether the remote host is
1218 router and register the re-connect timeout if it is. It used
1219 to check that whether we are normal server, but router must do
1220 auto-reconnect with another router as well. Affected file
1223 * Removed the [<key len>] option from CMODE command as the cipher
1224 name decides the key length, nowadays. See the defined ciphers
1225 from the protocol specification.
1227 * Added [<hmac>] option to the CMODE command to define the HMAC
1228 for the channel. Added SILC_CMODE_HMAC channel mode.
1230 * Added [<hmac>] option for the JOIN command so that user can
1231 select which HMAC is used to compute the MACs of the channel
1234 * Added Hmac field to the Channel Message Payload. The integrity
1235 of plaintext channel messages are now protected by computing
1236 MAC of the message and attaching the MAC to the payload. The
1237 MAC is encrypted. Now, it is clear that this causes some
1238 overhead to the size of the packet but rationale for this is that
1239 now the receiver can verify whether the channel message decrypted
1240 correctly and also when private keys are set for the channel the
1241 receiver can decrypt the packet with several keys and check from
1242 the MAC which key decrypted the message correctly.
1244 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1245 lib/silccrypt/silccipher.[ch].
1247 * Added silc_hash_len to return the digest length into the
1248 lib/silcrypt/silchash.[ch].
1250 * Rewrote parts of Silc Channel Payload interface in the
1251 lib/silccore/silcchannel.[ch]. The encode function now also
1252 encrypts the packet and parse function decrypts it.
1254 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Fixed a minor formatting bug in the SKE's key material processing.
1257 It actually might have processed the keys wrong way resulting
1260 * Redefined the mandatory HMAC algorithms and added new algorithms.
1261 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1262 and hmac-md5 truncated to 96 bits. The mandatory is now
1263 hmac-sha1-96. Rest are optional (including the one that used
1264 to be mandatory). Rationale for this is that the truncated HMAC
1265 length is sufficient from security point of view and can actually
1266 make the attack against the HMAC harder. Also, the truncated
1267 HMAC causes less overhead to the packets. See the RFC2104 for
1270 * Added new [hmac] configuration section. The SKE used to use
1271 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1272 is of course wrong. The official names that must be proposed in
1273 the SKE are the ones defined in the protocol specification
1274 (hmac-sha1-96 for example). The user can configure any hmac
1275 using any hash function configured in the [hash] section. At
1276 least, the mandatory must be configured.
1278 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1280 * Added HMAC list to the SKE proposal list. It has now both
1281 hash algorithm list and HMAC list. This makes the protocol
1282 incompatible with previous versions. The SKE now seems to work
1283 the way it is supposed to work, for the first time actually.
1285 * Defined plain Hash algorithms to the protocol specification.
1288 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Implemented support for key agreement packets into the server.
1291 Added functions silc_server_key_agreement and
1292 silc_server_send_key_agreement. Other than these functions,
1293 server has nothing to do with this packet.
1295 * Added support for private message key packets into the server.
1296 Added functions silc_server_private_message_key and
1297 silc_server_send_private_message_key.
1301 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1302 called in the protocol's final callback instead in the END
1303 protocol state. This makes a little more sense and in the same
1304 time in client we can use the same protocol routines for normal
1305 key exchange and to key agreement packet handling as well.
1307 * Added to both client's and server's KE protocol context the
1308 SilcSKEKeyMaterial pointer to save the key material. We will
1309 bring the key material to the protocol's final callback by doing
1310 this. The final callback must free the key material.
1312 * Added SKE's packet_send callback into client's KE protocol
1313 context so that the caller can choose what packet sending function
1314 is used. This way we can use different packet sending when
1315 doing normal SKE when doing key agreement packet handling (in
1316 the key agreement packet handling we do not want to encrypt
1319 * Implemented the responder side of the key agreement routines
1320 in the client. The client can now bind to specified port and
1321 accept incoming key negotiation. The key material is passed
1322 to the application after the protocol is over.
1324 * Implemented the processing of incoming Key Agreement packet
1325 in the client. Added function silc_client_key_agreement to
1328 * Implemented the intiator side of the key agreement routines
1329 in the client. The client can now initiate key agreement with
1330 another remote client. The key material is passed to the
1331 application after the protocol is over.
1333 * Created client_keyagr.c to include all the key agreement
1336 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1337 SILC_TASK_CALLBACK except that it is not static.
1339 * Created client_notify.c and moved the Notify packet handling
1340 from the client.[ch] into that file.
1342 * Created client_prvmsg.c and moved all private message and
1343 private message key routines from the client.[ch] into that file.
1345 * Create client_channel.c and moved all channel message and
1346 channel private key routines from the client.[ch] into that file.
1348 * Changed silc_client_get_client_by_id_resolve to resolve with
1349 WHOIS command instead of IDENTIFY command, in the file
1350 lib/silclient/idlist.c.
1352 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1354 * Implemented the SKE's responder side to the Client library.
1356 * When FAILURE is received to the protocol do not trust it
1357 blindly. Register a timeout to wait whether the remote closes
1358 the connection as it should do it, only after that process the
1359 actual failure. This was changed to both client and server.
1361 * Added client_internal.h to include some of the structures
1362 there instead of client.h in lib/silcclient/.
1364 * Added function silc_task_unregister_by_callback to unregister
1365 timeouts by the callback function.
1367 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Some "Incomplete WHOIS info" errors has been appearing on the
1370 log files. Took away the entry->userinfo check from WHOIS
1371 reply sending. The entry->userinfo is now " " if client did not
1372 provide one. I thought this was fixed earlier but something
1373 is wrong still. Let's see if the error still appears.
1375 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Fixed a minor bug in the login when the channel key is
1378 re-generated in the server. It used to generate the key in
1379 wrong order and thus caused problems in the channel traffic.
1381 * Fixed a minor bug in channel key distsribution after
1382 KICK command. The key was not sent to the router even though
1385 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Added silc_ske_process_key_material_data as generic routine
1388 to process any key material as the SILC protocol dictates. The
1389 function is used by the actual SKE library but can be used by
1390 applications as well. This relates to the private message keys
1391 and the channel private keys since they must be processed the
1392 same way the normal SILC session keys. The protocol dictates
1393 this. Affected files: lib/silcske/silcske.[ch].
1395 Added also silc_ske_free_key_material to free the
1396 SilcSKEKeyMaterial structure.
1398 * Defined silc_cipher_set_key function to set the key for
1399 cipher without using the object's method function. The affected
1400 files: lib/silccrypt/silccipher.[ch].
1402 * Implemented silc silc_client_add_private_message_key,
1403 silc_client_add_private_message_key_ske,
1404 silc_client_del_private_message_key,
1405 silc_client_list_private_message_keys and
1406 silc_client_free_private_message_keys functions in the
1409 Added functions silc_client_send_private_message_key to send
1410 the Private Message Key payload and silc_client_private_message_key
1411 to handle incoming Private Message Key payload.
1413 * Added Cipher field to the Private Message Key payload to set
1414 the cipher to be used. If ignored, the default cipher defined
1415 in the SILC protocol (aes-256-cbc) is used.
1417 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Removed lib/silcclient/ops.h file.
1421 Redefined parts of the SILC Client Library API. Created new
1422 file silcapi.h that deprecates the ops.h file and defines the
1423 published Client Library API. Defined also private message key
1424 API and channel private key API into the file.
1426 This is the file that the application must include from the
1427 SILC Client Library. Other files need not be included by
1428 the application anymore.
1430 * Added new key_agreement client operation callback and also
1431 defined the Key Agreement library API for the application.
1433 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1436 is used by clients to request key negotiation between another
1437 client in the SILC network. If the negotiation is started it
1438 is performed using the SKE protocol. The result of the
1439 negotiation, the secret key material, can be used for example
1440 as private message key.
1442 Implemented the Key Agreement payload into the files
1443 lib/silccore/silauth.[ch].
1445 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Redefined ciphers for the SILC protocol. Added some new ciphers
1448 and defined the key lengths for the algorithms. Changed the
1449 code accordingly. The default key length is now 256 bits.
1451 * Fixed SKE key distribution function silc_ske_process_key_material
1452 when the key length is more than 128 bits. The default key
1453 length in SILC is now 256 bits.
1455 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1456 to indicate unsupported algorithm.
1458 * Renamed rijndael.c to aes.c and all functions as well.
1460 * Fixed a long standing channel key setting bug in client library.
1461 Weird that it has never surfaced before.
1463 * Fixed bug in channel deletion. If the entire channel is removed
1464 then it must also delete the references of the channel entry
1465 from the client's channel list as the client's channel entry and
1466 the channel's client entry share same memory.
1468 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Implemented CONNECT and SHUTDOWN commands in the client.
1472 * Implemented CLOSE command to the client.
1474 * Added the function silc_idlist_find_server_by_name into the
1475 files silcd/idlist.[ch].
1477 Added the function silc_idlist_find_server_by_conn into the
1478 files silcd/idlist.[ch].
1480 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * DIE command was renamed to SHUTDOWN. Updated the both code
1485 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1486 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1488 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1491 * Added function silc_server_create_connection function to create
1492 connection to remote router. My server implementation actually
1493 does not allow router to connect to normal server (it expects
1494 that normal server always initiates the connection to the router)
1495 so the CONNECT command is only good for connecting to another
1498 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1501 or some other client was kicked from the channel.
1503 Implemented the handling of the notify type to both client
1506 Implemented silc_server_send_notify_kicked to send the KICKED
1507 notify. It is used to send it to the server's primary router.
1509 * Implemented the KICK command into server and client.
1511 * Added `query' argument to the silc_idlist_get_client function
1512 to indicate whether to query the client from server or not if
1515 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1516 to indicate that the client is not channel founder.
1520 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Removed the rng context from SilcPacketContext structure and
1523 changed that the packet routine uses the Global RNG API.
1525 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added support for quit message that client can "leave" on the
1528 channel when it quits the SILC. It is ditributed inside the
1529 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1531 Added silc_server_free_client_data that will take the
1532 signoff message as argument.
1534 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1536 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Updated parts of the protocol specification to keep it up
1541 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1544 payloads in one packet.
1546 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1547 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1548 use now the new List flag.
1550 * Also deprecated the following packet types: REPLACE_ID,
1551 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1553 * Added list support for Notify packet in server.
1555 * Added silc_server_send_notify_channel_change to send the
1556 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1557 the silc_server_send_replace_id.
1559 * Added silc_server_send_notify_nick_change to send the
1560 NICK_CHANGE notify type. Deprecates the function
1561 silc_server_send_replace_id.
1563 * Added silc_server_send_notify_join to send the JOIN notify type.
1564 Deprecates the function silc_server_send_new_channel_user.
1566 * Added silc_server_send_notify_leave to send LEAVE notify type.
1567 Deprecates the function silc_server_send_remove_channel_user.
1569 * Added silc_server_send_notify_cmode and
1570 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1571 types. Deprecates the silc_server_send_set_mode function.
1573 * Added SERVER_SIGNOFF notify type to indicate that server has
1574 quit. This means that all clients on the channel from that
1575 server will drop. This can be also used when netsplit happens.
1577 Deprecated REMOVE_ID packet type since it is not needed anymore
1580 Added silc_server_send_notify_server_signoff to send the
1581 SERVER_SIGNOFF notify type. Deprecates the function
1582 silc_server_send_remove_id.
1584 Added also silc_server_send_notify_signoff to send the
1585 SIGNOFF notify type.
1587 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1588 SILC protocol from this day on. Changed the protocol
1589 specification as well.
1591 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1592 notify type. It is used between routers to notify about
1593 topic changes on a channel.
1595 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1598 * Partly updated the protocol specification to comply with the
1599 changes now made. It is still though a bit outdated.
1601 * The JOIN notify type now takes one extra argument <Channel ID>.
1602 The packet used to be destined to the channel but now the
1603 JOIN type may be sent as list thus it is impossible to
1604 destine it to any specific channel. By adding this argument
1605 it is again possible.
1607 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Added CREDITS file. The CHANGES and CREDITS file will appear
1610 in the distribution as well.
1612 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1615 types in the server's silcd/packet_receive.c.
1617 * Implemented CMODE and CUMODE to work in router environment.
1619 * Fixed minor encoding and decoding buglet from the
1620 lib/silccore/silcmode.c.
1622 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1625 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1627 * Changed all SilcConfigServer* and silc_config_server* to
1628 SilcServerConfig* and silc_server_config*, respectively.
1631 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Associated the ID (client or server ID) to the Authentication
1634 Payload to avoid any possibility of forging. Updated the
1635 protocol specification and the code accordingly.
1637 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * The RSA key length is now save to the RsaKey context in the
1640 key generation process in lib/silccrypt/rsa.c. The key length
1641 is now used to figure out the maximum size of the block allowed
1642 to be encrypted/signed.
1644 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1645 is equivalent to the silc_mp_mp2bin but does not allocate any
1648 * Changed silc_mp_mp2bin API to take length argument. If it is
1649 non-zero then the buffer is allocated that large. If zero, then
1650 the size is approximated using silc_mp_sizeinbase, which however
1653 * Created Global RNG API which is global RNG that application can
1654 initialize. After initializing, any routine anywhere in the
1655 code (including library) can use RNG without allocating a new
1656 RNG object. This was done to allow this sort of use of the
1657 RNG in code that has no chance to allocate RNG object. All
1658 applications currently allocate this and many routines in the
1659 library use this. Affected file lib/silccrypt/silcrng.[ch].
1661 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1662 it to use the Global RNG API.
1664 * Defined Authentication Payload into protocol specification that
1665 is used during SILC session to authenticate entities. It is
1666 used for example by client to authenticate itself to the server
1667 to obtain server operator privileges.
1669 Implemented this payload into the lib/silccore/silcauth.[ch].
1670 Implemented also routines for public key based authentication
1671 as the new protocol specification dictates.
1673 Moved definitions of different authentication methods from
1674 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1676 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1677 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1678 silc_pkcs_verify_with_hash functions into the file
1679 lib/silccrypt/silcpkcs.[ch].
1681 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * The client entry's userinfo pointer must be always valid.
1684 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1685 will fail since it requires the userinfo. Now, the userinfo
1686 is allocated as "" if actual userinfo does not exist. Actually,
1687 it must exist and it is totally Ok to drop client connections
1688 that does not announce the userinfo. However, we will make
1689 this workaround for now.
1691 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1692 to return the remote port by socket.
1694 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1697 SILC_SERVER_PENDING_EXEC and added an new macro
1698 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1699 data or when error occurs while processing the pending command.
1701 Added new argument `destructor' into silc_server_command_pending
1702 and to the SilcServerCommandPending object. This destructor is
1703 now called after calling the pending callback or if error occurs
1704 immediately. If error occurs the actual pending callback won't
1705 be called at all - only the destructor. The destructor may be
1706 NULL if destructor is not needed.
1708 All this applies for client library code as well. Similar
1709 changes were made there as well for the pending commands.
1711 In the client, the application must now allocate the
1712 SilcClientCommandContext with the silc_client_command_alloc
1715 * Added reference counter to the SilcServerCommandContext. Added
1716 function silc_server_command_alloc and silc_server_command_dup
1719 Same type of functions added to the client library for the same
1722 * Removed the cmd_ident from IDListData away since it is now
1723 global for all connections. It is the command identifier used
1724 in command sending and with pending commands. The affected file
1727 * Added reference counter to the SilcSocketConnection objecet to
1728 indicate the usage count of the object. The object won't be
1729 freed untill the reference counter hits zero. Currently only
1730 server uses this, and client ignores it. The client must be
1731 set to use this too later. The affected files are
1732 lib/silccore/silcsockconn.[ch]. Added also the function
1733 silc_socket_dup to increase the reference counter.
1735 This was mainly added because it is possible that the socket
1736 is removed underneath of pending command or other async
1737 operation. Now it won't be free'd and proper DISCONNECTING
1738 flags, etc. can be set to avoid sending data to connection that
1739 is not valid anymore.
1741 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1742 the connection. After that it sets SILC_SET_DISCONNECTED.
1743 It is, however, possible that the socket data is not still freed.
1744 The silc_server_packet_process now checks that data is not
1745 read or written to connection that is DISCONNECTED. The socket
1746 get's freed when the reference counter hits zero.
1748 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Changed the client operation API: channel_message operation's
1751 `sender' is now the client entry of the sender, not the nickname
1752 and the `channel' is the channel entry, not the channel name.
1754 In the private_message operation the `sender' is now also the
1755 client entry of the sender not the nickname.
1757 Affected file is lib/silcclient/ops.h and all applications
1758 using the client operations.
1760 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Moved the calling of ops->connect() from connect_to_server_final
1763 into receive_new_id functin since that is the point when the
1764 client is actually allowed to send traffic to network. The
1765 affected file is lib/silcclient/client.c.
1767 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1770 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1771 (if needs broadcasting) instead of broadcasting the packets one
1772 by one which would make a burst in the network traffic.
1774 * Added `broadcast' argument to the functions in silcd/server.[ch]
1775 silc_server_create_new_channel[_with_id] to indicate whether
1776 to send New Channel packet to primary router.
1778 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Added new function into the silcd/server.[ch] files:
1781 silc_server_create_new_channel_with_id to create new channel with
1782 already existing Channel ID.
1784 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1785 lib/silccore/silcpacket.h. This packet is used t send list of
1786 Set Mode payloads inside one packet. Server uses this to set
1787 the modes for the channels and clients on those channels, that it
1788 announced to the router when it connected to it. The protocol
1789 specification has been updated accordingly.
1791 * The silc_server_new_channel did not handle the packet coming
1792 from normal server as it normally does not send that. However,
1793 when it announces its channels it does send it. Implemented
1794 the support for that.
1796 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1797 into the file lib/silccore/id.h.
1799 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Fixed memory leaks in the functions silc_idlist_del_client,
1802 silc_idlist_del_channel and silc_idlist_del_server in the file
1803 silcd/idlist.c. All of those leaked like a sieve.
1805 * Fixed some small memory leaks in the client's function
1806 silc_client_notify_by_server.
1808 * Added functions into silcd/server.c: silc_server_announce_clients,
1809 silc_server_announce_channels and silc_server_announce_server.
1810 These functions are used by normal and router server to announce
1811 to its primary router about clients, channels and servers (when
1812 router) that we own. This is done after we've connected to the
1815 These functions effectively implements the following packet types:
1816 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1817 and SILC_PACKET_NEW_ID_LIST.
1819 * Added new functions into the silcd/packet_receive.[ch]:
1820 silc_server_new_id_list, silc_server_new_channel_list and
1821 silc_server_new_channel_user_list to handle the incoming
1822 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1824 * Added support of changing Channel ID in the function
1825 silc_server_replace_id. If the server that announces a channel
1826 to the router already exists in the router (with same name but
1827 with different Channel ID), router is responsible to send
1828 Replace ID packet to the server and force the server to change
1829 the Channel ID to the one router has.
1831 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1832 client that the Channel ID has been changed by the router. The
1833 normal server sends this to the client. Client must start using
1834 the new Channel ID as the channel's ID.
1836 Implemented handling of this new type into lib/silcclient/client.c
1837 into the function silc_client_notify_by_server.
1839 * Added new function silc_idlist_replace_channel_id into the files
1840 silcd/idlist.[ch] to replace the Channel ID.
1842 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Call silc_server_command_identify_check always when processing
1845 the IDENTIFY command in silcd/command.c
1847 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1849 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1850 send keepalive packets. The packet can be sent by clients,
1851 servers and routers.
1853 Added function silc_socket_set_heartbeat into the file
1854 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1855 If not set, the heartbeat is not performed. The actual
1856 heartbeat is implemented in the low level socket connection
1857 library. However, application is responsible of actually
1860 Added silc_server_send_heartbeat to send the actual heartbeat
1861 packet into silcd/packet_send.[ch]. Server now performs
1862 keepalive with all connections.
1864 * Added silc_task_get_first function into lib/silcutil/silctask.c
1865 to return the timeout task with shortest timeout. There was a bug
1866 in task unregistration that caused problems. TODO has been
1867 updated to include that task system must be rewritten.
1869 * The client library will now resolve the client information when
1870 receiving JOIN notify from server for client that we know but
1871 have incomplete information.
1873 * Rewrote parts of silc_server_remove_from_channels and
1874 silc_server_remove_from_one_channel as they did not remove the
1875 channel in some circumstances even though they should've.
1877 * Encryption problem encountered in server:
1879 The LEAVE command used to send the Channel Key packet to the
1880 router immediately after generating it. However, the code
1881 had earlier sent Remove Channel user packet but not immediately,
1882 ie. it was put to queue. The order of packets in the router
1883 was that Channel Key packet was first and Remove Channel User
1884 packet was second, even though they were encrypted in the
1885 reverse order. For this reason, MAC check failed. Now, this
1886 is fixed by not sending the Channel Key packet immediately but
1887 putting it to queue. However, this is more fundamental problem:
1888 packets that are in queue should actually not be encrypted
1889 because packets that are sent immediately gets encrypted
1890 actually with wrong IV (and thus MAC check fails). So, packets
1891 that are in queue should be encrypted when they are sent to
1892 the wire and not when they put to the queue.
1894 However, the problem is that the current system has not been
1895 designed to work that way. Instead, the packet is encrypted
1896 as soon as possible and left to the queue. The queue is then
1897 just purged into wire. There won't be any fixes for this
1898 any time soon. So, the current semantic for packet sending
1901 o If you send packet to remote host and do not force the send
1902 (the packet will be in queue) then all subsequent packets to the
1903 same remote host must also be put to the queue. Only after the
1904 queue has been purged is it safe again to force the packet
1907 o If you send all packets immediately then it safe to send
1908 any of subsequent packets through the queue, however, after
1909 the first packet is put to queue then any subsequent packets
1910 must also be put to the queue.
1912 Follow these rules and everything works fine.
1914 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Added new function silc_server_remove_clients_by_server to
1917 remove all client entries from ID list when the server connection
1918 is lost. In this case it is also important to invalidate all
1919 client entires as they hold the invalid server entry. This
1920 fixes fatal bug when server has lost connection and will reconnect
1923 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Made some sanity checks to silc_server_daemonise like to check
1926 whether the requested user and group actually exists.
1928 * Added sanity check to SKE's silc_ske_responder_finish to check
1929 that the public and private key actually is valid.
1931 * Invalidate the client's nickname when receiving Replace ID
1932 packet and the Client ID is being replaced. This means that the
1933 server will query the nickname if someone needs it (client)
1936 * Sort the ID Cache in client library when the ID Cache data
1937 has changed (needs sorting).
1939 * Do not allow for SILC client to create several connections to
1940 several servers. The client does not support windows right now
1941 and generating multiple connections causes weird behaviour.
1943 Irssi-silc client does support windows and can handle several
1944 connections without problems, see: www.irssi.org and SILC plugin.
1946 * Fixed some places where client was added to the IDList. The
1947 rule of thumb is following (in order to get everything right):
1948 If the client is directly connected local client then the
1949 `connection' argument must be set and `router' argument must be
1950 NULL to silc_idlist_add_client function. If the client is not
1951 directly connected client then the `router' argument must
1952 bet set and the `connection' argument must be NULL to the
1953 silc_idlist_add_client function.
1955 * The funtion silc_server_packet_send_local_channel actually did
1956 not check whether the client was locally connected or not. It
1957 does that now. Fixed a bug related to LEAVE command.
1959 * Fixed Remove Channel User payload parsing bug in server's
1960 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1962 * The server's silc_server_save_channel_key now checks also the
1963 global ID list for the channel as it might not be in the local
1964 list. Fixed a bug related to LEAVE command.
1966 * Is this the end of the [<unknown>] buglet that has been lurking
1967 around for a long time? A little for loop fix in server's
1968 silc_server_command_whois_parse that is used by both IDENTIFY
1969 and WHOIS command. At least, this was a clear bug and a cause
1970 of one type of [<unknown>] buglet.
1972 * WHOIS and IDENTIFY commands call the function
1973 silc_server_command_[whois/identify]_check function even if
1974 we are not router server.
1976 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added --with-gmp configuration option. If set the GMP
1979 is always compiled in the SILC source tree. If not set then
1980 it is checked whether the system has the GMP3 installed. If
1981 it has then the GMP won't be compiled (the system's headers
1982 and library is used), if it doesn't have it then the GMP is
1983 compiled in the SILC source tree.
1985 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Changed RSA private exponent generation to what PKCS #1
1988 suggests. We try to find the smallest possible d by doing
1989 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1990 not security fix but optimization.
1992 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Added new config entry [Identity] to fork the server and run
1995 it as specific user and group. A patch from Bostik.
1997 * Imported Dotconf configuration library into lib/dotconf.
1998 This will be used to create the SILC configuration files later.
1999 It will appear in the distsribution after this commit.
2001 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * A big code auditing weekend happening. Auditing code for
2004 obvious mistakes, bugs and errors. Also, removing any code
2007 Removed files for being obsolete:
2009 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2010 inline in the file lib/silcutil/silcbuffer.h)
2012 o lib/silcutil/silcbufutil.c (the header has inline versions)
2014 Changed code to fix possible error conditions:
2016 o The buffer formatting routines now check that the destination
2017 buffer really has enough space to add the data. This applies for
2018 both buffer formatting and unformatting
2019 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2020 unformatting was changed to accomodate following rules:
2021 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2022 sent to the function while XXX_*STRING will not allocate or copy
2023 the data into the buffer. Instead it sets the pointer from the
2024 buffer into the pointer sent as argument (XXX_*STRING used to
2025 require that the pointer must be allocated already). This change
2026 makes this whole thing a bit more consistent and more optimized
2027 (note that the data returned in the unformatting with XXX_*STRING
2028 must not be freed now). The routines return now -1 on error.
2030 o Tried to find all code that use buffer_format and buffer_unformat
2031 and added return value checking to prevent formatting and
2032 especially unformatting errors and possible subsequent fatal
2035 o Changed ske->x and ske->KEY to mallocated pointers in
2036 lib/silcske/silcske.h. Fixed possible data and memory leak.
2038 o Added return value checking to all *_parse* functions. Fixed
2039 many memory leaks as well.
2041 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2042 so that buffer overflows would not happen. All code now also
2043 checks the return value as it can fail.
2045 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Added reconnection support to server if the normal server looses
2048 its connection to the router (for example if router is rebooted).
2049 The server performs normal reconnection strategy implemented
2050 to the server. Affected file silcd/server.c.
2052 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Added new packet type SILC_PACKET_SET_MODE that is used to
2055 distribute the information about changed modes (for clients,
2056 channels and clients channel modes) to all routers in the
2057 network. Updated the protocol specification accordingly.
2059 Added functions into silcd/packet_send.c and
2060 silcd/packet_receive.c: silc_server_send_set_mode,
2061 silc_server_set_mode.
2063 Added new files silcmode.[ch] into lib/silccore that implements
2064 the encoding and decoding of Set Mode Payload. Added new type
2065 SilcSetModePayload. Moved the definitions of different modes
2066 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2068 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Oops, a little mistake in server's connection authentication
2071 protocol. The protocol is not ended with FAILURE but with
2072 SUCCESS if the authentication is Ok. :) Affected file is
2075 * Implemented NICK_CHANGE notify handling in server in the file
2076 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2077 the local clients on the channel. After the changing nickname
2078 in router environment snhould work and the [<unknown>] nickname
2079 should appear no more.
2081 The silc_server_replace_id function that receives the Replace ID
2082 payload now sends the NICK_CHANGE notify type also in the file
2083 silcd/packet_receive.c
2085 * Changed WHOIS and IDENTIFY command to support the maximum amount
2086 of arguments defined in protocol specs (3328 arguments). This
2087 fixed a bug that caused problems when there were more than three
2090 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added extra parameter, command identifier, to the
2093 silc_client_send_command so that explicit command identifier
2096 Changed that ID list routines uses specific command identifier
2097 when sending WHOIS/IDENTIFY requests to the server so that they
2098 can be identified when the reply comes back.
2100 Affected files lib/silcclient/command.[ch],
2101 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2103 * Added `sender' argument to silc_server_packet_send_to_channel
2104 to indicaet the sender who originally sent the packet to us
2105 that we are now re-sending. Ignored if NULL. Affected file
2106 silcd/packet_send.[ch].
2108 * Added some server statistics support in silcd/server_internal.h
2109 SilcServerStatistics structure and around the server code. Also
2110 send some nice statistics information when client is connecting
2113 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Fixed channel ID decoding in server's JOIN command reply in
2116 silcd/command_reply.c
2118 * Fixed braodcasting of replace ID payload to not to send it if
2119 we are standalone server in silcd/packet_receive.c.
2121 * Fixed all channel message sending routines to not to send
2122 packets to clients that has router set, since they are routed
2123 separately in the same function earlier. Affects file
2124 silcd/packet_send.c and all channel packet sending functions.
2126 * In USERS reply, res_argv[i] are not allocated, the table
2127 is allocated. Thus changed that free the table, not its
2130 * In server's whois_check and identify_check if the client is
2131 locally connected do not send any WHOIS commands - they are not
2134 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Fixed some minor bugs in client when sending WHOIS command. The
2137 arguments was in wrong order.
2139 * Removed statis function add_to_channel from server in
2140 silcd/command.c that was previously used with the joining but
2143 * Tested USERS command in router environment successfully with two
2144 routers, two servers and two clients.
2146 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Reorganized the USERS command and command reply in client library
2149 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2150 When the command is given by user we register a pending command
2151 callback that will reprocess the command after the reply has been
2152 received from the server. When reprocessing the packet we then
2153 display the information. Thus, the USERS information is displayed
2154 now in the command callback instead of in the command reply
2155 callback. The processing of the command is same as previously
2156 when server has sent the command reply in the JOINing process.
2158 * Added to USERS command in silcd/command_reply.c to join the client,
2159 we didn't use to know about, to the channel after we've created
2160 a client entry for it. Also, for clienet we did know already still
2161 check whether it is on the channel or not and add it if not.
2163 * Removed silc_server_command_join_notify as the function and its
2166 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Changed the client's pending command handling to the same as the
2169 server's pending command handling. It is also now possible to
2170 execute command reply functions from other command reply
2171 function as the function callbacks for commands and command
2172 replies are one and same. The pending commands are not static
2173 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2174 in client connection context. Thus, pending commands are server
2175 connection specific as it is convenient.
2177 Changed the function silc_client_command_pending and
2178 silc_client_command_pending_del and added new function
2179 silc_client_command_pending_check. Removed the
2180 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2183 * Added cmd_ident, current command identifier, to the client
2184 connection context in lib/silcclient/client.h to keep track on
2185 command identifiers used in command sending. Client's command reply
2186 function handling now supports the mandatory command identifiers.
2188 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2189 funtions in client to fully support pending command callbacks.
2191 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2192 as one of the arguments to the application in the command reply
2195 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2196 before first releasing SILC but came back. Now it is removed again
2197 and should come back nomore. The FORWARDED flag was used only
2198 by the JOINing procedure by forwarding the command packet to router.
2199 Now, the JOINing procedure has been changed to more generic (due
2200 to various router environment issues) and FORWARDED is not needed
2201 anymore for anything. The protocol specification is yet to be
2204 Now, removed silc_server_packet_forward from server and the flag
2205 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2207 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Renamed NAMES command to USERS command. The NAMES was named that
2210 due to historical reasons. Now it is renamed. Also, rewrote
2211 parts of the USERS command. The nickname list is not sent anymore
2212 by the server. Only Client ID and mode lists are sent in the USERS
2213 command. Changed this also to the protocol specification.
2215 The client now resolves the names and stuff after it receives
2216 the USERS list from the server when joining to the channel.
2218 * WHOIS and IDENTIFY commands has been changed to support multiple
2219 Client ID's per command. One can now search for multiple users
2220 in the network by sending only one WHOIS or IDENTIFY command.
2221 Changed the code and the protocol specifications.
2223 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2224 uses silc_server_command_whois_parse to parse the request. */
2226 * If normal server, do not parse the WHOIS and IDENTIFY requests
2227 before sending it to the router. Saves some time.
2229 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Fixed JOIN command on client library. Wrong number of arguments
2232 used to crash the client.
2234 * Added silc_server_channel_has_global function to check whether
2235 channel has global users or not.
2237 * Added silc_server_channel_has_local function to check whether channel
2238 has locally connected clients on the channel.
2240 * The silc_server_remove_from_one_channel now checks whether the
2241 channel has global users or not after given client was removed from
2242 the channel. It also checks whether the channel has local clients
2243 on the channel anymore. If it does not have then the channel entry
2244 is removed as it is not needed anymore.
2246 * The silc_server_notify now checks on JOIN notify whether the joining
2247 client is one of locally connected or global. If it is global then
2248 the channel has now global users on the channel and that is marked
2249 to the channel entry. Also, it now saves the global client to
2250 global list who is joining and JOINs it to the channel. This is
2251 for normal server, that is.
2253 Changed silc_server_send_notify_on_channel,
2254 silc_server_packet_relay_to_channel and
2255 silc_server_packet_send_to_channel check if we are normal server
2256 and client has router set (ie. global client) do not send the
2257 message to that client, as it is already routed to our router.
2259 * Implemented LEAVE notify type handling in silc_server_notify
2262 * Tested LEAVE command in router environment successfully. Tested
2263 with two routers, two servers and two clients.
2267 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2269 * Implemented SIGNOFF notify type handling in silc_server_notify
2272 * silc_server_remove_id now removes the client entry from all channels
2273 it has joined and thusly sends SIGNOFF notify type.
2275 * Rewrote the NAMES list generation in server by removing two excess
2276 loops. The lists are created now inside one loop.
2278 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * silc_server_remove_channel_user checks now also global list
2281 for channel and client.
2283 * silc_server_new_channel_user checks now both local and global
2284 list for channel and client. Fixed a bug in client id decoding.
2285 Used to decode wrong buffer.
2287 * silc_server_channel_message checks now both local and global
2288 list for channel entry.
2290 * Tested channel joining (hence JOIN) in router environment
2291 successfully. Tested with two routers, two servers and two
2294 * Tested channel message sending in router environment successfully.
2296 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Added silc_server_save_channel_key into server.[ch] to save the
2299 received channel key in Channel Key payload processing. It is
2300 also used in JOIN command reply handling.
2302 Equivalent function silc_client_save_channel_key added into
2303 client.[ch] into client library.
2305 * Changed JOIN command reply to send information whether the channel
2306 was created or not (is existing already) and the channel key
2307 payload. Changed protocol specs accordingly.
2309 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2310 the request was sent by ID and not by nickname. Crashed on
2313 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2316 now correctly save the received data.
2318 * silc_server_free_sock_user_data now notifies routers in the
2319 network about entities leaving the network.
2321 At the same time implemented functions silc_server_remove_id
2322 and silc_server_send_remove_id to receive and send REMOVE_ID
2323 packets. The packet is used to notify routers in the network
2324 about leaving entities. The ID removed will become invalid in
2327 * Added function silc_idlist_del_server into server. Removes and
2328 free's server entry from ID list.
2330 * silc_server_private_message function now checks, if we are router,
2331 that the destination ID really is valid ID, naturally.
2333 * In router when NEW_ID packet is received (for new client) the
2334 hash of the Client ID is saved in the ID Cache but the
2335 client->nickname is set to NULL, instead of putting the hash
2338 IDENTIFY command now also checks that client->nickname must be
2339 valid. If it is not if will request the data from the server who
2340 owns the client. Added new function
2341 silc_server_command_identify_check.
2343 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2344 to set the command to already allocated Command Payload.
2346 * Tested private message sending in router environment with two
2347 routers, two servers and two clients. Fixed minor bugs and now
2350 * Fixed segfault from client's NAMES command. Used to crash if
2353 * Forwarded packets must not be routed even if it is not destined
2354 to the receiver. Changed server code comply with this.
2356 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Added `require_reverse_mapping' boolean value to ServerParams
2359 structure. If TRUE (not default) the server will require that
2360 the connecting host has fully qualified domain name.
2362 If the reverse mapping is not required and hostname could not be
2363 found the IP address is used as hostname.
2365 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Implemented version string checking to both client and server.
2368 The check is incomplete currently due to the abnormal version
2369 strings used in development version of SILC.
2371 * Changed all command functions in server to use the new
2374 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Changed char *data to unsigned char *data in ID Cache system to
2377 support binary data as ID Cache data. Changed code to support
2378 binary data in lib/silccore/idcache.c.
2380 * Renamed silc_server_packet_relay_command_reply to
2381 silc_server_command_reply as it is normal packet receiving
2382 function. Rewrote the function to accept command replys for
2383 servers and not only for clients.
2385 * Mark remote router always as registered server if we are connecting
2386 to it. Otherwise, commands sent by the router to us are ignored.
2388 * All ID List find routines now returns the ID Cache Entry pointer
2389 as well if requested.
2391 * WHOIS command works now in router environment, tested with two
2392 routers, two servers and two clients.
2394 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2395 in router environment (as it is almost equivalent to WHOIS) but
2396 hasn't been tested thoroughly. Added new functions:
2398 silc_server_command_identify_parse
2399 silc_server_command_identify_send_reply
2400 silc_server_command_identify_from_client
2401 silc_server_command_identify_from_server
2403 * Disabled route cache adding because adding two different ID's with
2404 same IP replaces the old cache entry thus giving wrong route.
2405 The entry->router->connection is always the fastest route anyway
2406 so route cache may not be needed. Of course, new routes maybe
2407 established after receiving the ID when the entry->router->connection
2408 might not be anymore the most optimal.
2410 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Add route cache for received ID for fast routing.
2414 * Added silc_server_packet_route to route received packet on router
2415 that is not destined to us.
2417 * Renamed silc_server_get_route to silc_server_route_get.
2419 * Added id_string and id_string_len fields into SilcServer to
2420 include encoded ServerID for fast comparing without excess
2421 encoding of the ID's.
2423 * Cleaned up WHOIS command on server side. Added following static
2426 silc_server_command_whois_parse
2427 silc_server_command_whois_check
2428 silc_server_command_whois_send_reply
2429 silc_server_command_whois_from_client
2430 silc_server_command_whois_from_server
2432 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2433 arguments in command replies. All command functions should be
2434 updated to use this macro.
2436 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Minor typo fixes on command reply handling on server.
2440 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Added silc_server_command_add_to_channel internal routine to add
2443 the client to the channel after router has created the channel and
2444 sent command reply to the server.
2446 * Added generic silc_server_send_command to send any command from
2449 * Use static buffer with ID rendering instead of duplicating data.
2451 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Fixed a channel user mode bug when joining to a channel server gave
2454 everybody channel founder rights, oops.
2456 * We mark ourselves as the router of the incoming server connection
2457 if we are router ourselves. This way we can check in some packet
2458 sending functions whether it is locally connected server. For
2459 incoming router connections we put NULL.
2461 * For router sending packets locally means now always sending the
2462 packet cell wide; to local clients and local servers. For normal
2463 server sending packet locally means sending it to only local
2466 * Fixed the JOIN command to really work in router environment. If the
2467 channel is created it is always created by the router. Router is
2468 also responsible of making the initial joining to the channel,
2469 sending JOIN notify to the sending server and distributing
2470 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2471 does not exist server doesn't do anything else but forward the
2472 command to the router which performs everything.
2474 * Added silc_server_send_channel_key function to send the Channel Key
2477 * Added silc_server_create_channel_key to create new channel key. The
2478 channel key is now re-generated everytime someone joins or leaves
2479 a channel, as protocol dictates. Note: channel->key_len is the
2482 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2485 packet_receive.[ch] to separate packet sending and receiving
2486 routines. The server.[ch] now includes everything else including
2487 actual packet processing (writing and reading data) and other
2490 Renamed silc_server_private_message_send_internal to
2491 silc_server_send_private_message. The routine is still though
2492 used only to relay private messages as server does not send
2493 private messages itself.
2495 Renamed silc_server_new_channel to silc_server_create_new_channel
2496 and added new function sicl_server_new_channel that handles the
2497 incoming New Channel packet. Added also new sending function
2498 silc_server_send_new_channel to send New Channel Payload.
2500 * Added new function silc_server_notify to process incoming notify
2501 packet to the server/router. Server may then relay the notify
2502 to clients if needed.
2504 * Added new function silc_server_new_channel_user to process incoming
2505 New Channel User packet. Router will redistribute the packet and
2506 send JOIN notify to its local clients and locally connected servers
2507 if needed. Normal server will send JOIN notify to its local client
2508 on same channel when received this packet. Added also corresponding
2509 sending function silc_server_send_new_channel_user to sent the
2512 * Added boolean route argument to send_notif_to_channel and
2513 packet_send_to_channel functions to attempt to route the packet
2514 if it is TRUE and send only locally if it is FALSE.
2516 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * silc_server_replace_id now broadcasts the received replace ID
2519 packet if it is not broadcast packet already. The router must
2520 broadcast to inform other routers about changed ID.
2522 * Added backpointer to server's router into SilcServer context in
2523 silcd/server_internal.h.
2525 * Fixed silc_server_packet_broadcast to send correct broadcast
2528 * The channel key is now distributed to the local client as soon
2529 as it is received from the router (in router environment) so that
2530 no other packet may be sent for the channel until client has
2533 * silc_server_remove_channel_user now broadcasts the received
2534 Remove Channel User packet if it is not broadcast packet already.
2535 The router must broadcast to inform other routers about removed
2538 * Added users field into SilcPacketContext that is a reference count
2539 of the context. One can increase the reference count by calling
2540 silc_packet_context_dup which is now changed to just increase the
2541 reference count instead of duplicating the data. The reference
2542 count is decresed by calling silc_packet_context_free that will
2543 free the data after the reference count hits zero.
2545 For now on the packet context and everything allocated into it
2546 (including the raw packet from network) must be freed by calling
2547 the new silc_packet_context_free function. Added also new function
2548 silc_packet_context_alloc that must be used now to allocate the
2549 context. This also means that if a routine is asynchronous from
2550 silc_[client/server]_packet_parse_type the packet context must
2551 be duplicated by calling silc_packet_context_dup. Otherwise it
2552 gets free'd after silc_[client/server]_packet_parse_type returns.
2553 Also, one must remember that if packet is duplicated then its
2554 reference count must be decresed by calling the free function as
2555 many times as it was duplicated.
2557 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2558 from both client and server.
2560 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Made joining to a channel working in router environment.
2564 * Cleaned up JOIN command on server side and create function
2565 silc_server_command_join_channel internal routine to make the
2568 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Changed silc_command_pending list to SilcDList. Also, added
2571 `ident' field to SilcServerCommandPending structure to identify
2572 the reply and to call correct callback.
2574 Added silc_server_command_pending_check function to replace the
2575 corresnponding macro. The silc_command_pending list is not
2578 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2579 to set identifier to previously allocated Command Payload. It
2580 is used to set identifier for command when resending Command
2583 * Added silc_command_payload_encode_payload to encode Command
2584 Payload buffer from SilcCommandPayload structure.
2586 * Added silc_argument_payload_encode_payload to encode Argument
2587 payload buffer from SilcArgumentPayload structure.
2589 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Changed WHOIS command to support router connection on server side.
2592 The whois request is always sent to router unless the server is
2593 standalone server. After server has received the reply from the
2594 router will it send the reply to the client.
2596 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2597 broadcast received broadcast packet. The function is used only
2598 by router. The broadcast packet is always sent to the router's
2601 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2602 render given ID to printable string, for log files for example.
2604 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Made basic router to router connections working. At least they
2607 can now connect to each other but nothing really works the way
2608 they are supposed - yet.
2610 * Added new initiator token to RouterConnection configuration
2611 file in silcd/serverconfig.[ch]. It is used to tell whether we
2612 are the initiator to the remote router or whether we'll expect
2613 the other end to connect.
2615 * Moved registering of listener task to silc_server_init, hence
2616 the server starts listenning as soon as it is run, even if it
2617 does not have connections to other routers. Let's see how well
2620 * Changed default connection retry timeouts for more suitable in
2623 * Removed cipher and such arguments from silc_idlist_add_client
2624 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2625 Added new function silc_idlist_add_data to add the keys and stuff
2628 * Added SilcIDListData structure and added it to SilcClientEntry
2629 and SilcServerEntry as their first field in the structure. This
2630 way we can explicitly cast the ID entries to the SilcIDListData
2631 structure and get common data for the entries. In past, we had
2632 to first check what type of connection it is and then cast it to
2633 correct ID entry type. Now, we can directly cast the opaque
2634 pointer to the SilcIDListData (no matter what ID entry it actually
2635 is) and get the data needed.
2637 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2640 in some circumstances even if threre were timeout tasks, though not
2641 IO tasks, but tasks anyway. Now fixed.
2643 * Defined SilcServerConnection structure to hold connection specific
2644 stuff about directly connected servers and routers. The definition
2645 is currently in silcd/server_internal.h. I thought about having
2646 a bit more important role fro this struct but for now it is used
2647 only when connecting to other server (or router actually).
2649 * Added connecting retry support in server when connecting to
2650 router(s). The retry feature implement exponential backoff
2651 algorithm. Also, added SilcServerParams structure to hold default
2652 parameters for server. For now, it include these retry settings
2653 and are hard coded. After server is moded to be as Silc Server
2654 Library this structure will be more important.
2656 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Changed client librarys channel->clients table to SilcList and
2659 changed code accordingly.
2661 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Changed client's channel table to SilcList and changed code
2664 accordingly. Also changed SilcChannelClientEntry to include back-
2665 pointer to the channel so that client entry can use that structure
2666 as list as well and we have fast cross-reference to the channel.
2667 This change dramatically decreased the complexity of channel
2668 handling with client entry and vice versa (removed one extra
2669 loop when searching for channel entry from many functions).
2671 * Changed server->sim from table to SilcDList and changed code
2674 * NAMES command can now be used from user interface. It will show
2675 the user list on the channel, neatly.
2677 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2678 Code now saves realname of the user if it becomes available.
2680 * Renamed configure.in to configure.in.pre and made ./prepare
2681 script to automatically add correct version string to
2682 configure.in which it creates from configure.in.pre.
2684 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * NAMES command reply now shows users mode with the nickname when
2689 * Moved silc_client_ch[u]mode[_char] functions from
2690 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2691 place sucks, they are utility functions and should be in some
2694 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2696 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2699 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added TRQ (efficient deque and list library) into lib/trq. This is
2704 a very good list library that is currently used in the SILC. Defined
2705 SilcList API over the library because I didn't like the API very
2706 much. See lib/trq/silclist.h for the API and examples of how to
2707 use the API. Fixed various places in the code to use the new
2708 SilcList API. The SilcList is meant for lists that has a structure
2709 already defined as a list. It is not suitable to add just some
2710 context to the list (in TRQ, the context is the list actually).
2712 So, I defined SilcDList that can be used for the purpose where
2713 predefined list structure does not exit. This can be used as
2714 such list. Now some context just can be added to the SilcDList.
2715 Currently this list is not used in the SILC just yet, though there
2716 are a lot places where this can replace dynamically allocated
2717 tables and I will fix these places, later, to use SilcDList.
2718 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2719 and use TRQ internally).
2721 Also fixed some annoying warning messages that the original TRQ
2722 code generated. Also minor changes to TRQ's Makefile.in.
2724 * Added support for querying by Client ID to both WHOIS and
2725 IDENTIFY commands into server, as required by the protocol.
2727 * Removed method function pointers from SilcBuffer structure. They
2728 weren't used to anything and just increased the context size for
2729 no good reason. This change also made silc_buffer_alloc and
2730 silc_buffer_free functions inline functions.
2732 * Disabled command flooding detection support until it's fixed so
2733 that it accepts commands in but does not execute them more than once
2736 * Added silc_net_localhost(), to return local hostname, into
2737 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2738 that must be initialized before calling silc_client_init.
2740 * Added new function: silc_server_send_notify_on_channels to send
2741 notify messages to all channels client has joined. It is assured
2742 that the message is sent only once per client.
2744 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2745 lib/silcutil/silcutil.[ch] as silc_format function. The new
2746 function is generic and is used by server as well, not only by
2747 the logging routines.
2749 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2750 the provided version string was not acceptable. Added new function:
2751 silc_ske_check_version into lib/silcske/silcske.h. The function
2752 must be implemented by the application (client or server) and it
2753 does not reside in the SKE library. The function checks the version
2754 string remote end sent.
2756 * Added back pointers (to opaque context and to SilcSocketConnection)
2757 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2759 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2760 duplicate packet context structure.
2762 * Changed `notify' client operation to send same arguments as client
2763 receives from server except for ID's. ID's are mapped to correct
2764 ID entry and that is returned. Also, if channel entry is not sent
2765 by server but the notify is for channel the channel entry is sent
2766 to application (otherwise application doesn't know that it is for
2767 channel (library gets it from packet's Destination ID)).
2769 * Added silc_client_remove_from_channels into client library to
2770 remove a client from all channels it has joined to. Used when
2771 received SIGNOFF notify from server. Added also new function
2772 silc_client_replace_from_channels to replace old ID entry with
2773 new ID entry on all channels. Used when received NICK_CHANGE
2776 * Fixed ID Cache list handling in silc_idlist_get_client in
2777 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2778 to get (or query) client by ID.
2780 * Updated TODO list.
2782 * Added connection authentication status message defined by the
2783 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2784 support for these into the code in client and server side.
2786 * Added generic function silc_client_send_command to send any command
2787 with variable argument list. Application should use this function
2788 to send commands if the command functions provided by the library
2789 does not suite for the application's user interface needs.
2791 * Added new `failure' client operation. Application is notified about
2792 received failure packet if client is executing a protocol. In this
2793 case the protocol's execution has failed.
2795 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2796 is required by the protocol.
2798 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2799 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2802 * Added status flag to SilcSKE object to indicate realtime status
2803 of the SKE protocol.
2805 * Application receives now exactly same command reply arguments as
2806 the library receives from server. However, if ID is received the
2807 corresponding ID entry is returned to the application (eg. Client
2808 ID is mapped to correct SilcClientEntry entry and that is returned).
2809 Changed command_reply client operation due to this change.
2811 * Changed all ID's in commands and in command replys as ID Payloads.
2812 Change affected both client and server side codes.
2814 All ID's sent in SILC network (with execption of ID's in SILC
2815 Packet header) are sent in ID Payload to support variable length
2818 * Server now notifies nick changes and notifies all clients on
2819 the channels about the new nickname (about the new Client ID,
2822 * Implemented CMODE command to change channel modes. Supports all
2823 channel modes defined by the protocol specs except ban and invite
2824 lists. (Also, private channel key mode is supported but support for
2825 setting private channel key in client is missing, thus, this mode
2826 has no effect on client side (except that server requires that the
2827 client uses private channel key and normal channel traffic does not
2830 Also, invite mode works per se, but INVITE command does not work
2831 yet correctly, so you can set channel as invite only channel but
2832 inviting clients to the channel does not work (it is yet to be
2833 thought what's the best way to do it).
2835 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2836 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2837 Implemented CUMODE command to change user's mode on the channel.
2838 Supports all modes defined by the protocol specs.
2840 * Added NAMES command reply to return users modes on the channel.
2842 * Removed unnecessary and slow ciphers from lib/silccrypt.
2844 * Set SO_KEEPALIVE option to connection sockets by default.
2846 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2848 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2849 redefined the Notify Payload into protocol specs.
2851 * Added silc_id_payload_parse_id to get ID directly from raw
2854 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2857 accept searching by Client ID as well.
2859 * Added support for LEAVE and SIGNOFF notify types in client library.
2861 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2862 to parse ID Payload from raw data.
2864 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Added flags parameter into silc_ske_assemble_security_properties
2867 function in lib/silcske/silcske.[ch].
2869 * Changed notify client operation to fit better for notify messages
2870 sent by server. The notify payload received from server is now
2871 passed to the application (after parsing it to SilcNotifyPayload).
2872 It is application's responsibility to retrieve the arguments
2873 from the payload and show the message the way it wants. The message
2874 sent by server is implementation specific.
2876 * Changed public keys to comply with the protocol specification.
2877 Old public keys are not supported anymore and are not compatible.
2879 * Removed nickname from Channel Payload as the latest draft removed
2880 it. The client must resolve the nickname from the NAMES command
2881 reply received when it joined the channel.
2883 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2885 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Fixed some errors in protocol specification drafts.
2889 * Created lib/silccore/silcnotify.c to implement Notify Payload
2890 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2891 generic payloads described by protocol specifications. The file
2892 includes implementations for ID Payload and Argument Payload.
2894 * Changed Command Payload implementation to use the new Argument
2895 Payload. Changed command_xxxx_payload to command_payload_xxxx
2896 to comply with SILC coding conventions.
2898 * Added suppport for Argument Payload handling in Notify Payload
2899 implementation as protocol requires it. Added the new support
2900 into server and client lib as well.
2902 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Added support for multiple nicknames on same channel. [n] is
2905 added locally to the nickname if there are more than one same
2906 nicknames on the channel.
2908 * Server now sends all nicknames that matched WHOIS request.
2909 Client also shows the list received from server.
2911 * Added TOPIC command to client side. User can now set and show
2912 current topic on channel.
2914 * Added MOTD command to client and server. Also, server sends the
2915 motd when client connects to the server.
2917 * Changed version strings to comply ISO 8601.
2919 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Fixed protocol error handling in client library. It should now
2922 cope even if the SKE fails for some reason.
2924 * Made new protocol specification drafts for submitting to IETF.
2926 * Implemented TOPIC command to server in silcd/command.c.
2928 * Added two new notify types into lib/silccore/silcnotify.h:
2929 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2930 notify nickname change and topic setting/change on a channel.
2932 * API change of command_reply operation in client library. The
2933 application gets now the status type received from server as well.
2935 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2939 * Cras fixed and optimized the packet handling even further and
2940 it should work now. Minor change to the prototype of function
2941 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2943 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Added new function into lib/silcutil/silcschedule.[ch]:
2946 silc_schedule_with_fd to select() a specified fd. The function
2947 returns after timeout expires or data arrives or goes. The
2948 function is used by packet routines to wait that all data is
2949 received from network.
2951 * Fixed data reading from network in lib/silccore/silcpacket.c.
2952 The code now assures that all data is read from the fd and then
2953 continues packet processing. This was a bug fix since the code
2954 used to drop some data in some circumstances.
2956 * Added new function into lib/silcclient/client.[ch]:
2957 silc_client_start_key_exchange to start key exchange after
2958 connection has been established to server. The code internally
2959 now uses this funtion but its main purpose was to provide it
2960 for applications that perform their own connecting. After
2961 application has created a connection it merely calls this
2962 function to start the key exchange between client and server.
2963 The library takes care of everything else after that.
2965 Updated also lib/silcclient/README to explain the usage of
2968 * Do not send to application information that connection has
2969 been established. Application gets notified it by connect
2972 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Applied cras's patch to add silc_schedule_one function. The
2975 function runs scheduler once and returns.
2977 * Fixed the scheduler after cras messed it up. The timeout
2978 handling works now as it's supposed to work.
2980 * Added into lib/silccore/ silcnotify.h to include notify
2981 message types support. Changed silc_server_send_notify*
2982 functions, in server.[ch], to support those new notify types.
2983 Added the support for the notify types into client library,
2984 as well. Added new notify client operation into ops.h in
2987 * Changed silc_server_packet_send_to_channel to send normal
2988 packets instead of just channel message packets. The function
2989 is now used to send the notify packets to channels. It is not
2990 used to send channel message packets anymore, as server never
2993 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2994 va_arg()s as it seems to require it nowadays. I guess, if SILC
2995 is compiled with older va_arg() the new code should work anyway.
2997 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Splitted core library. Core library (lib/silccore) includes
3000 now only SILC protocol specific core (and common) components.
3001 Created new utility library (lib/silcutil) that includes more
3002 generic purpose stuff. The stuff for util library was taken
3003 from the old core library. This was minor and easy split.
3005 * Created SILC Client Library (lib/silcclient) that includes
3006 implementation of the SILC client without user interface. This
3007 was major move from silc/ directory. The code has been changed
3008 so that it is transparent towards the user interface. The
3009 silc/ directory includes now the same user interface as before
3010 and it uses the new client library. Read lib/silcclient/README.
3011 Basicly, the client library performs everything else related
3012 to SILC except user interface handling. Also, configuration
3013 files are considered to be part of user interface and library
3014 does not handle them.
3016 This change also changed a lot of structures, function naming etc.
3017 Most important change was that SilcClientWindow object was
3018 renamed to SilcClientConnection in the client library. Created
3019 also new file lib/silcclient/ops.h. Also added new files
3020 silc/local_command.[ch] and silc/client_ops.[ch].
3022 All these changes were made to make it easier for user interface
3023 designers to create what ever user interface for the SILC client
3026 It is also expected that the server will be moved to lib
3027 directory as well and SILC Server Library will be created;
3028 sometimes in the future.
3030 * Removed Local commands from lib/silccore/silccommand.h as
3031 they are application specific and new client library does not
3032 handle any of those anymore.
3034 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3035 old client implementation in silc/.
3037 * Added support for callback functions in SILC_LOG_* macros.
3038 Application can now set its own callbacks that will be called
3039 instead of using the default functions that will always print
3040 the debug messages to stderr (or stdout). Also, debugging can
3041 now be disabled by setting silc_debug to FALSE and re-enabled by
3042 setting it to TRUE. Note, that logging will still work even
3043 if debugging is disabled.
3045 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3046 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3047 silc_log_reset_debug_callbacks.
3049 * To enable debugging in silc client one must give now -d
3050 option on command line.
3052 * Changed silc_schedule_init to automatically allocate task queues
3053 if they are not allocated before calling it.
3055 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Added GMP 3.1 into math library.
3059 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3062 a channel in SILC network. The packet is used by servers and
3063 routers to notify other routers that user has left a channel.
3064 This little feature was missing until now. Added the feature
3065 to protocol specification as well.
3067 Added functions: silc_server_send_remove_channel_user and
3068 silc_server_remove_channel_user into server.[ch].
3070 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3071 lib/silccore/silcpacket.h. However, they are not implemented
3074 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed joining to a channel and sending channel messages
3077 between server and router. The channel message sending should
3078 now work inside a cell.
3080 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Fixed the private message sending between server and router.
3083 The private message sending should now work inside a cell.
3085 * Added silc_server_replace_id into server.[ch] to replace
3086 existing ID in the SILC network.
3088 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3089 and silc_idlist_replace_server_id into idlist.[ch] in server.
3091 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Fixed the server to server connections. Server can again now
3094 connect to router. Router to router connections probably does
3097 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Added dynamic protocol registering support. Now protocols can
3100 registered and unregistered on the fly. Patch by cras.
3102 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Added lib/contrib directory to hold routines that some platforms
3105 don't have but are needed by SILC.
3107 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3108 into lin/contrib to provide getopt() and getopt_long() for
3109 those who don't have it.
3111 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Added AWAY command to client. When away message is set and
3114 client receives a private message packet the client automatically
3115 replies to the sender with the away message.
3117 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3118 bug seemed to be the cause of recent problems when compiling
3121 * Added version detection support to SKE protocol specification
3122 and added the new changes to the SKE implementation as well.
3123 There were other minor changes in the SKE protocol as well.
3125 Many changes in lib/silcske/silcske.[ch] and in
3126 lib/silcske/payload.[ch].
3128 * Added ^U functionality, clear input line. Patch from cras.
3130 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Mainly small bugfixes on core library. Fixed some debugging
3133 logging and buffer overflow in silclog.c.
3135 * Updated config.sub and config.guess on the distribution tree.
3137 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added command lagging support in server. Client may execute
3140 commands now only once in two seconds.
3142 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Optimized packet reception. MAC computation and checking is now
3145 also more optimized. A lot previously duplicated code is now
3146 used as generic by both client and server.
3148 * Fixed key pair generation in clientutil.c
3150 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Added into lib/silccore/silcbufutil.[ch] new function;
3153 silc_buffer_realloc.
3155 * Moved generic packet sending/encryption functions to
3156 lib/silccore/silcpacket.[ch] from client and server. Some
3157 rewriting of the functions.
3159 * Moved all generic packet reception/decryption functions to
3160 lib/silccore/silcpacket.[ch] from client and server. The
3161 packet processing is now much cleaner in both client and server.
3162 These were major changes in both client and server.
3164 * Created many common functions in server to do packet sending.
3165 Previously code were duplicated a lot, this has been removed
3168 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Rewrote major parts of the ID cache system. Don't know
3171 whether it is better now or not but at least the API is more
3174 * Major rewrite on ID cache stuff on client because of the ID
3175 cache API changes. Added idlist.c to client.
3177 * Also major rewrite on ID cache stuff on server as well.
3178 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3179 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3180 in hand, instead they are all put into the ID cache system now.
3181 All server_idlist_* routines uses ID cache now instead of
3182 traversing its own lists (those lists does not exist anymore).
3183 SilcIDList though still exists. Also, SilcXXXEntry's are
3186 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Finally made the SKE implementation compliant to the protocol
3189 specification. All mp integers are now binary encoded as
3190 opposed being HEX encoded.
3192 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3195 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3196 functions: silc_[encode/decode]_pem. Also added function
3197 silc_encode_pem_file to PEM encode with newlines ('\n') for
3200 * SILC public keys are now encoded either PEM or binary. Same
3201 option is for private keys as well. By default private keys
3202 are binary encoded and public keys PEM encoded. Silly HEX
3203 encoding were removed.
3205 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3206 function to create fingerprints.
3208 * Fixed a bug in SHA1; does not change the original data anymore.
3210 * Partly implemented INFO command on client and server side.
3211 Fixed CLEAR command. Changes to SERVER command; show current
3212 server(s) when giving command without arguments. Added
3213 VERSION command to client.
3215 * Added check to server that unregistered connections cannot
3216 execute commands (unless it is specificly allowed).
3218 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Fixed screen refresh.
3222 * Fixed channel joining bug from client. On some circumstances
3223 client tried to join to a channel it had already joined.
3225 * Added public key verification process into client's protocol.c.
3226 The client now verifies the public key from user and saves
3227 it into ~./silc/serverkeys/ directory.
3229 Added into: clientutil.[ch]: silc_client_verify_server_key.
3231 * Changed SKE protocol's silc_ske_initiator_finish function
3232 to accept callback function that verifies the received public
3233 key. Removed old silc_ske_verify_public_key function.
3235 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3238 silc_pkcs_private_key[_data]_set.
3240 * Made the password and public authentication more cleaner in
3241 server's protocol.c.
3243 * Removed historic and obsolete protocol `channel_auth' from
3244 both client and server.
3246 * Removed wrong way of sending command status messages from
3247 server to client in server's command.c. The old way violated
3248 protocol specification.
3250 Changes to silccore/silccommand.[ch]: removed
3251 silc_command_encode_status_payload -> not needed anymore,
3252 changed silc_command_encode_payload_va to accept extra
3253 argument on variable argument list. The argument type must
3254 now be provided to the function. Also, added new function:
3255 silc_command_encode_reply_payload_va which is same as
3256 normal command_encode_payload_va except command status type
3257 is provided as extra argument.
3259 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Added ~./silc directory handling. The directory includes the
3262 public and private keys for the client.
3264 Added silc_client_check_silc_dir, silc_client_create_identifier
3265 and silc_client_load_keys.
3267 * Implemented SILC protocol compliant public key. Added public
3268 and private key saving to and loading from files.
3270 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3271 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3272 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3273 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3274 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3276 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3277 silc_pkcs_load_[public/private]_key.
3279 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added silc_server_get_route (route.[ch]) to get connection
3282 data for the fastest route for given ID.
3284 * Implemented INVITE command on client and server. The command
3285 were re-defined in the SILC Protocol Specification and the
3286 implementation now complies with the specification.
3288 * Implemented PING command on client and server.
3290 * Implemented NAMES command on client and server. The server side
3291 supports currently only normal server not router server yet.
3292 Some changes to NAMES definition in SILC protocol specification.
3294 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Implemented LEAVE command on client and server.
3298 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3299 again. This change was made to the protocol as well. Server
3300 should not violate the protocol specification anymore.
3302 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3305 was tested. SOCKS4 was not but should work anyway.
