3 * Moved the channel message encrypting in the router betwen
4 router connections from silc_server_channel_message to the
5 silc_server_packet_relay_to_channel since we want to check
6 whether we have anybody channel before encrypting anything.
7 Affected files silcd/packet_[receive/send].c.
9 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Fixed the [AdminConnection] server config section to support
12 multiple entries. Affected file silcd/serverconfig.c.
14 * Added support into the server to check the validity of the
15 incoming connection before executing any KE or authentication
18 * The connection configuration is now saved to the KE and
19 connection auth protocol contexts and not fetched anymore in
20 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
22 * The local hosts listenning address and port is also resolved
23 now when starting the server. We want to have the socket object
24 to include the real address and port for the listener. Added
25 new function silc_net_check_local_by_sock into the files
26 lib/silcutil/silcnet.[ch].
28 * Fixed a broadcast bug in server -> do not broadcast if we
31 * Fixed a routing bug. Do not route broadcast packets ever.
32 Broadcast packets must be processed always and not routed since
33 they may be destined to some other host than yourself and thus
34 would get routed without no good reason. Affected file is
37 * Added function silc_server_config_is_primary_route to check
38 whether primary router connection has been configured (a router
39 configuration that we are initiating). If there is not, we
40 will assume that there is only two routers in the SILC network
41 and we will use the incoming router connection as our primary
42 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
44 * Changed the order of the broadcasting. Broadcast _after_ the
45 packet has been processed not before. Affected file is
48 * Fixed a [ClientConnection] parsing bug. The port was never
49 parsed correctly thus resulting to port 0. Affected file
52 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
53 argument and did not set the broadcast packet flag. Affected
54 file silcd/packet_send.c. Fixed same bug in the function
55 silc_server_send_notify as well.
57 * If we receive NEW_ID packet for our own ID in the server, ignore
60 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Removed the nickname from the Private Message Payload.
65 Updated the code and the protocol specs.
67 * Updated protocol specs for submitting to the IETF.
69 * Tweaked the Random Number Generator a bit. Affected file
70 lib/silccrypt/silcrng.c. Exported a new function
71 silc_rng_[global]_add_noise which can be used to add more
74 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Do not parse packets with different timeout when protocol
77 is active -> may cause problem with rekey. Affected file
80 * When server receives signoff notify it must not create
81 new channel key if the client is on any channels since the
82 sender of the signoff notify will create it.
84 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Added printing of error messages during SKE protocol from the
87 failure packet sent by server during SKE. Affected file
90 * Removed the client's failure_callback handling with timeout
91 and handle it immediately when received.
93 * The SKE library returned wrong type in SUCCESS and FAILURE
94 packets. They must be 32 bit MSB not 16 bit MSB.
96 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Ok, rewrote the logic of the re-key and now it seems to work.
99 I tested it on high traffic with frequent re-keys without
100 problems. Added hmac_receive (and renamed hmac to hmac_send)
101 in SilcClientConnection in lib/silcclient/client.h and
102 in SilcIDListData in silcd/idlist.h. Also, removed the
103 SilcPacketParserContext's cipher and hmac fields as they are
104 not needed anymore and actually caused some problems when
105 the ciphers and hmac's changed underneath the packet parser.
107 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * If re-key protocol is active then process the incoming packets
110 synchronously since we must assure that icoming packets encrypted
111 with the old key is processed before the new keys is set to
112 use. This is true other packets than for REKEY packets.
113 Affected file silcd/server.c. The same was done to client library
114 as well, affected file lib/silcclient/client.c.
116 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Fixed bug in client and server to accept the force send if
119 the packet is send from silc_[server/client]_packet_process
120 function. Otherwise the packets are never delivered, oops.
122 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Disable force sending of packets when REKEY protocol is active.
125 We must assure that no packet is sent directly when rekey is
126 performed. All packets must be sent through packet queue.
127 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
128 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
129 function is silc_[server/client]_packet_send_real to check
132 * Replaced the SIM paths from example config files to
133 /usr/local/modules. Also, make install creates now
134 /usr/local/silc/logs directory to hold all the SILC server
137 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Made the configure.in.pre work on Solaris. Patch by salo.
141 * Made all ciphers compatible with non-x86 machines. Defined
142 CBC mode macros into lib/silccrypt/ciphers_def.h.
144 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Fixed the make install.
148 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * When MAC computation fails the silc_packet_decrypt returned 0
151 even though it was supposed to return -1. Fixed this. The
152 affected file is lib/silccore/silcpacket.c.
154 * Do not replace the config files in /etc/silc (in make install)
155 if they already exist. Affected file ./Makefile.am.
157 * Do not send re-key packets immediately but through packet queue.
158 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
160 * Changed silc_net_check_host_by_sock to return FALSE if the
161 IP/DNS could not be resolved. Though, it returns the IP address
162 now even if it could not resolve it (but returns also FALSE).
163 Affected file lib/silcutil/silcnet.[ch].
165 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Added silc_pkcs_decode_identifier to decode the public key's
168 identifier. Affected file lib/silccrypt/silpkcs.[ch].
169 Added also silc_pkcs_free_identifier. Added also new context
170 SilcPublicKeyIdentifier.
172 * Added -S option to the silc client. It is used to dump the
173 contents of the specified public key file.
175 * Changed the PKCS api to return the public key length when
176 setting the public key.
178 * Fixed a fatal bug in the public and private key file loading.
179 Affected file lib/silccrypt/silcpkcs.c.
181 * Execute the packet parsing for client with zero (0) timeout
182 if the protocol is active. Affected file silcd/server.c.
184 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Made the key generation options to the silcd program. Added
187 -C option, equivalent to client's option.
189 * Added new [ServerKeys] config section to the server. It
190 configures the server's public and private key.
192 * Defined generic Public Key Payload into the protocol
193 specification to send specific type of public keys and
196 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
197 public key or certificate.
199 * Implemented the GETKEY command to the server and to the
200 client library and on user interface.
202 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
204 * Made preliminary `make install' work.
206 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Added SilcServerRekey context into silcd/idlist.h.
210 * Added the PFS support as defined in the specification to the
211 SKE protocol. Affected files lib/silcske/*.c.
213 * Added `ske_group' field to the SilcServerRekey context to hold
214 the number of the SKE group that is used with PFS in re-key.
215 Affected file silcd/idlist.h.
217 * Added PFS re-key support to the server. Affected file is
220 * Added silc_protocol_cancel to cancel execution of the next
221 state of the protocol. Affected file is
222 lib/silccore/silcprotocol.[ch].
224 * Added the re-key support with and without PFS to the client
225 library. Re-key is performed once in an hour, by default.
227 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
228 Added silc_client_rekey_callback and silc_client_rekey_final.
229 Affected files are lib/silcclient/protocol.[ch] and
230 lib/silcclient/client.[ch].
232 * Removed the `hmac_key' and `hmac_key_len' fields from the
233 SilcClientConnection structure; not needed. Affected file is
234 lib/silcclient/client.h.
238 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
240 * Do not ask whether user wants to use the negotiated private key
241 for private messages, just use it. Affected file is
242 silc/local_command.c.
244 * Added `send_enc_key' and `enc_key_len' fields to the
245 SilcIDListData structure since they are needed in the re-key
246 phase. Affected file is silcd/idlist.[ch].
248 * Implemented the simple re-key protocol into the server.
249 Affected files silcd/server.c and silcd/protocol.[ch]. The
250 re-key will be performed once in an hour, by default.
252 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
253 Added silc_server_rekey, silc_server_rekey_callback and
254 silc_server_rekey_final.
256 * Removed Tunneled flag from the protocol. Updated the code
257 and the specifications.
259 * Adde `pfs' field to the SilcIDListData to indicate whether
260 the PFS is to be performed in the re-key. Affected file is
263 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
266 int64 of at least the xintXX size. If void * is less that 4
267 bytes uint32 * will be used. Defined bool as boolean.
269 * Changed _ALL_ unsigned long and unsigned int to uint32,
270 unsgined short to uint16 in the source tree.
272 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
273 not handle clients that has entry->data.registered == FALSE.
274 They are not in the network anymore. Affected file is
277 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Implemented the sending of the SERVER_SIGNOFF notify in the
280 server. Affected file is silcd/server.c.
282 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
283 Added also silc_notify_payload_encode_args into the
284 lib/silccore/silcnotify.[ch].
286 * Implemented ther SERVER_SIGNOFF notify handling in the server.
287 Affected file silcd/packet_receive.c.
289 * Implemented the SERVER_SIGNOFF notify handling in the client
290 library. Affected file lib/silcclient/client_notify.c. Also,
291 implemnted the printing of the SERVER_SIGNOFF info to the
292 application. Affected file silc/client_ops.c.
294 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
295 if the deleting was successful. Affected file silcd/idlist.[ch].
297 * Added support for public key authentication in the connection
298 authentication protocol in the client library. Affected file
299 lib/silcclient/protocol.c.
301 * Changed the server's silc_idlist_get_clients_by_* interface
302 to support already allocated array so that new entries may be
303 added to pre-allocated array. Affected file silcd/idlist.[ch].
304 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
307 * All command reply functions in the server now calls the
308 pending command callback even if error occured. This way the
309 error will be delivered to the client as well. Affected files
310 silcd/command.c and silcd/command_reply.c.
312 * Fixed INFO command to return local server's info if no server
313 was provided. Affected file lib/silcclient/command.c.
315 * Removed RESTART command for good. Updated the code and the
318 * Rewrote parts of the task system. It is a bit simpler now.
319 Removed unsued task priorities. The affected files are
320 lib/silcutil/silctask.[ch].
322 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Moved the USERS printing from the library to the application.
325 Affected files lib/silcclient/command.c and silc/client_ops.c.
327 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Added channel key re-key support. The re-key is perfomed
332 only by the router and is done once in an hour. Added `rekey'
333 field to the SilcChannelEntry in the server. Affected files
334 silcd/server.c and silcd/idlist.h.
336 * Added silc_task_unregister_by_context into the file
337 lib/silcutil/silctask.[ch].
339 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Added SILC_UMODE_GONE mode to indicate when the client is not
342 present in the SILC network. Added also support to the local
343 command AWAY that will set this mode. Added support of showing
344 "xxx is gone" in WHOIS command. The USERS command shows the
347 * Fixed setting server and router operator privileges in the
348 server's UMODE command. Affected file silcd/command.c.
350 * Merged the SKE KE1 and KE2 payloads into one payload. The
351 new KE payload is equivalent to the old KE2 payload.
353 Cleaned up the SKE Start Payload parsing. It now uses the
354 simple buffer unformatting to do the parsing. A lot faster
357 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
358 to the SKE that is used to indicate whether both of the SKE
359 parties should perform authentication. By default only the
360 responder performs authentication. By setting this flag also
361 the initiator must do authentication. By default it is unset
362 since in normal SKE case, client to server connection, only
363 the responder should do authentication. When doing SKE between
364 two clients both should perform authentication. Updated the
365 code and the protocol specs.
367 * A little fix to IDENTIFY command in the server. Search the
368 client first by hash not nickname. Affected file is
371 * Fixed the silc_client_close_connection to support closing
372 the client to client connections wihtout deleting too much
373 data. Affected file lib/silcclient/client.c.
375 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
376 are received if protocol used to be active but is not anymore
377 the application would crash due to NULL pointer dereference.
378 Affected files silcd/server.c and lib/silcclient/client.c.
380 * Added `hash' field to the SilcClientConnection to include
381 the hash function negotiated in the SKE protocol.
383 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
384 to set the channel founder authentication data. A client can
385 claim the founder rights later by providing the authentication
386 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
387 This way the channel founder can regain the channel founder
388 privileges even it is left the channel. This works only on
389 local server and the client must be connected to the same
390 server to be able to regain the founder rights. Updated the
391 protocol specs accordingly.
393 Added support to the CMODE command in the client to set the
394 founder auth data. Read the README to see how to set it.
396 Added support to the CUMODE command to claim the founder
397 rights. Read the README to see how to do it.
399 Added support for the founder authentication to the Channel
400 Entry in the server. Affected file silcd/idlist.h.
402 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
403 server's CMODE command. Affected file silcd/command.c.
405 * Added the following new functions into lib/silccore/silcauth.[ch]:
406 silc_auth_get_method and silc_auth_get_data.
408 * The server now saves the remote hosts public key to the
409 SilcIDListData pointer. Affected file silcd/protocol.c.
411 * The normal server now does not remove the channel entry from
412 the cache if the founder authentication data is set. It used
413 to remove it if the founder was the last one on the channel on
414 the server and left the channel. The auth data is saved and
415 if the channel is re-joined later the old entry is used with
416 the old auth data. Affected files silcd/command_reply.c and
419 * Removed the `pkcs' field from the SilcIDListData structure
420 in the server; it is not used. Affected file silcd/idlist.h.
422 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Fixed packet processing on slow links. Partial packets were
425 never re-processed because the incoming data buffer was cleared
426 by the application. Application must not directly clear the
427 sock->inbuf, the packet processing routines handle it. Fixed
428 this in client library and in server.
430 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Fixed the WHOIS and IDENTIFY send reply function to really
433 check whether to send list or just one entry. Affected file
436 * Cleaned up the LEAVE command's channel key distribution. The
437 affected file silcd/command.c.
439 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
440 can enforce the channel mode as well. In that case the ID
441 includes the ID of the server. The code now enforces the
442 mode change if the router have different mode than the server.
444 * The notify client operation with CMODE_CHANGE notify can now
445 return NULL client_entry pointer if the CMODE was not changed
446 by client. Application must check for this.
448 * Added <Server ID> argument to INFO command to support server
449 info fetching by Server ID.
451 * Added silc_server_announce_get_channel_users to get assembled
452 packets of channel users of the specified channel. Affected
453 file silcd/server.[ch].
455 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
456 was freed underneath the ID Cache.
458 * Re-announce clients when the server received CHANNEL_CHANGE
459 notify from the router. Affected file silcd/packet_send.c.
461 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
464 crashed since it did not handle the fact that there is no cipher
465 called "3" and didn't check the error condition. Now fixed.
467 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
468 flag. It can be used to send message requests.
470 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Implemented the RESTART command in the client.
474 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
475 notice type messages. Added notice printing to the user
478 * The channel keys are not re-generated if the channel's mode
479 is PRIVKEY, ie private key on the channel exists. Affected
480 files silcd/server.c and silcd/command.c.
482 * Fixed a little bug in channel message delivery when channel
483 private keys are set in the server. Affected file is
486 * Changed the setting on channel->on_channel = TRUE from the
487 silc_client_save_channel_key to the JOIN command reply. The
488 key payload is not received if the private channel key is set.
489 Affected file lib/silcclient/command_reply.c and the
490 lib/silcclient/client_channel.c.
492 * When the CMODE_CHANGE notify is sent and the channel private
493 key mode is removed the channel key must be re-generated in
494 other cells as well. Added this support for the router in the
495 silcd/packet_receive.c.
497 * Added new local command NOTICE to send notice message on
498 channel. Affected file silc/local_command.[ch].
500 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Added new local command ME to the client. It is used to send
503 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
504 some action. Affected file silc/local_command.[ch].
506 * Changed channel_message and private_message client operations
507 to deliver the message flags to the application. Added also
508 the `flags' arguments to the silc_client_send_channel_message
509 and silc_client_send_private_message functions. Affected file
512 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Redefined the Private Message Payload to support private message
515 keys and to support the new private message flags. Updated
516 the protocol specs. Flags makes it possible to have for example
519 * Added new type SilcPrivateMessagePayload and defined an API
520 for it in the lib/silcclient/silcprivate.[ch].
522 * Tested private message private keys successfully. Tested the
523 private message key set, unset and list commands with the new
526 * Redefined the Channel Message Payload to include the channel
527 message flags (equal with private message flags) to support
528 for example CTCP style messages.
530 * Defined some of the message (for channel and private message)
531 flags. Updated the protocol specs and added the flags to the
532 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
534 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Added SilcKeyAgreementStatus type to the key agreement routines
537 to indicate the current status and error if one occured.
538 The status types are defined in the lib/silcclient/silcapi.h.
540 * Added new local command KEY that is used to set and unset private
541 keys for channels, set and unset private keys for private messages
542 with remote clients and to send key agreement requests and
543 negotiate the key agreement protocol with remote client. The
544 key agreement is supported only to negotiate private message keys,
545 it currently cannot be used to negotiate private keys for channels,
546 as it is not convenient for that purpose.
548 * Fixed a minor pending callback setting bug in the function
549 silc_client_get_client_by_id_resolve, now the function works.
550 Affected file lib/silcclient/idlist.c.
552 * Added function silc_net_get_local_port to get local bound
553 port by socket. Added to lib/silcutil/silcnet.[ch].
555 * Added `sockets' and `sockets_count' fields to the SilcClient
556 object. They hold the sockets of the listenning sockets in
557 the client. Listenning sockets may be for example the key
558 agreement server. Affected file lib/silcclient/client.[ch].
559 Added functions the silc_client_add_socket and the
560 silc_client_del_socket. They are exported to the application
563 * Added ~./silc/clientkeys to support other client's public keys.
565 * Renamed verify_server_key client operation to verify_public_key
566 and added one argument to indicate the type of the connection
567 (server, client etc.).
569 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Added silc_server_connection_auth_request to handle the
572 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
573 silcd/packet_receive.[ch].
575 * Added silc_server_send_connection_auth_request into the
576 silcd/packet_send.c to send the connection auth request packet.
578 * Cleaned up the silcd/protocol.c a bit and fixed some memory
581 * Fixed the public key authentication in responder side in the
582 server. The `auth_data' pointer includes the SilcPublicKey
583 not the path to the public key. Affected file silcd/protocol.c.
585 * Implemented the public key authentication in the initiator side
586 in the server. Affected file silcd/protocol.c.
588 * Removed the [RedirectClient] config section from the server
589 configuration. Is not needed and I don't want to implement it.
591 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
593 * Cleaned up the CMODE command in the server. It now works
594 correctly and supports all the modes defined in the protocol.
595 Affected file is silcd/command.c.
597 * Added `hmac_name' field to the SilcChannelEntry in the server
598 to hold the default HMAC of the channel. It can be set when
599 creating the channel (with JOIN command). Affected files
602 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
603 type to indicate the change of the current cipher and hmac
604 on the channel. Client can safely ignore the <cipher> argument
605 (if it chooses to do so) since the CHANNEL_KEY packet will
606 force the channel key change anyway. The <hmac> argument is
607 important since the client is responsible of setting the new
608 HMAC and the hmac key into use.
610 * Fixed the CMODE command in the client library as well.
612 * Tested CMODE command in router environment successfully.
614 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Show the version of the remote client (or server) when connecting
617 to the server. It is logged to the log file. Affected file
620 * Fixed the KILLED notify handling in the client library. The
621 client must be removed from all channels when receiving the
624 Also, do not remove the client entry when giving the KILL
625 command but when the KILLED notify is received.
627 * Removed silc_idlist_find_client_by_nickname from the server.
628 Not needed anymore. Affected files silcd/idlist.[ch].
630 * Implemented the CHANNEL_CHANGE notify type handling to the
631 server. Affected file silcd/server.c.
635 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
637 * Added silc_server_send_notify_invite to send the INVITE
638 notify between routers.
640 * Implemented the INVITE command correctly to the server.
642 * Implemented the INVITE notify type handling in the server.
644 * Implemented the INVITE command to the client library and on the
647 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Added function silc_server_get_client_resolve to find the
650 client entry by ID from all ID lists and then resolve it
651 (using WHOIS) if it cannot be found. Affected file is
654 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Implemented the BAN command to the client library.
658 * The JOIN command in the server now checks the invite list
661 * Changed the silc_command_reply_payload_encode_va and the
662 silc_command_payload_encode_va to support that if argument is
663 NULL it ignores and checks the next argument. Affected file
664 lib/silccore/silccommand.c.
666 * Added silc_server_send_notify_ban to send the BAN notify
667 type between routers.
669 * Chaned the silc_notify_payload_encode to support that if
670 argument is NULL it ignores and checks the next argument.
671 Affected file lib/silccore/silcnotify.c.
673 * Tested ban lists in router environment successfully.
675 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Implemented BAN command to the server, in silcd/command.[ch].
679 * Removed the BAN and INVITE_LIST modes from the CMODE command
682 * Added function silc_string_match to regex match two strings.
683 Affected files lib/silcutil/silcutil.[ch].
685 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Redefined parts of the SilcChannelEntry in the server to support
688 the new ban and invite lists.
690 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Redefined the INVITE command. The same command can be used to
693 invite individuals to the channel but also to manage the invite
694 list of the channel (to add to and remove from the invite list).
695 Updated the protocol specs.
697 * Added new command SILC_COMMAND_BAN that can be used to manage
698 the ban list of the channel. Updated the protocol specs.
700 * Removed the channel modes: the SILC_CMODE_BAN and the
701 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
702 in the CMODE command. The equivalent features are now available
703 using INVITE and BAN commands. Updated the protocol specs.
705 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
706 in the network about change in the current ban list. The notify
707 type is not used by the client.
709 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
710 support the invite lists.
712 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Added new function silc_string_regexify that converts string
715 including wildcard characters into regex string that can
716 be used by the GNU regex library. Added into the file
717 lib/silcutil/silcutil.[ch].
719 Added silc_string_regex_combine to combine to regex strings
720 into one so that they can be used as one regex string by
721 the GNU regex library. Added into the file
722 lib/silcutil/silcutil.[ch].
724 Added silc_string_regex_match to match two strings. It returns
725 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
727 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Imported GNU regex to the soruce tree into lib/contrib.
730 Fixed some compiler warning from the regex.c.
732 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Fixed MOTD command in the server to work in router environment.
736 * Fixed the MOTD command in the client library to support
737 the server argument in the command.
739 * Added `nickname_len' argument to the silc_idlist_add_client
740 in the server, as the `nickname' argument may be binary data
743 * Added silc_idlist_get_channels to return all channels from
746 * Implemented LIST command to the server. Affected file is
749 * Implemented the LIST command to the client library and on the
752 * Added [<user count>] argument to the LIST command reply.
753 With private channels the user count is not shown.
755 * Updated TODO and README.
757 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * The client entry's data.registered must be TRUE even with
760 global client entry on global client list. The data.registered
761 is used to check whether the client is anymore in the network,
762 for example with WHOWAS command so it must be valid.
764 * Fixed the WHOWAS command in the server. It now actually works
765 in router environment. Added function into silcd/command_reply.c
766 silc_server_command_reply_whowas_save.
768 * Added silc_idlist_purge function to the silcd/idlist.c
769 to periodically purge the ID Cache.
771 * Fixed INFO command in the server. It works now in router
772 environment. Added <server name> argument to the INFO command
773 reply. Updated the protocol specs.
775 * Fixed minor bug in silc_idcache_purge to not purge if the
776 expire value is zero.
778 * Fixed various bugs in WHOIS and IDENTIFY command handling as
779 they were buggy because of the WHOWAS information.
781 * Fixed local command MSG to handle the async resolving of
782 the remote client properly. It used to fail the first MSG.
783 Affected file silc/local_command.c.
785 * Added `data_len' field to SilcIDCache context.
787 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Update TODO. Todo in commands in the server.
791 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
794 used by routers as broadcast packet to inform other routers
795 about the changed user mode.
797 Implemented the notify handling in the server. Affected file is
798 silcd/packet_receive.c. Added the function
799 silc_server_send_notify_umode to the silcd/packet_send.[ch].
801 * Added new generic Channel Payload and deprecated the New Channel
802 Payload. The New Channel Payload is now the generic Channel
805 * Added new argument `mode' to the silc_server_send_new_channel
806 as it is required in the Channel Payload now.
808 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
809 and created a new and real SilChannelPayload to represent the
810 new generic Channel Payload. Implemented the encode/decode
811 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
813 * Added silc_server_get_client_channel_list to return the list
814 of channels the client has joined for WHOIS command reply.
815 Affected file silcd/server.[ch].
817 * Implemented the channel list sending in the WHOIS command reply
818 in server and in the client.
820 Implemented the channel list displaying on the user interface
821 as well. Affected file silc/client_ops.c.
823 * Added silc_channel_payload_parse_list to parse list of Channel
824 Payloads. It returns SilcDList list of SilcChannelPayloads.
825 Client for example can use this function to parse the list of
826 channels it receives in the WHOIS command reply. The caller
827 must free the list by calling silc_channel_payload_list_free.
828 Affected files lib/silccore/silcchannel.[ch].
830 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Added one new argument <user mode> to the WHOIS command reply
833 to return the mode of the user in SILC. Updated the protocol
836 Implemented it to the server and client.
838 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Fixed the mode printing on the user interface on joining.
841 Affected file silc/client_ops.c.
843 * Implemented the UMODE command and user modes in general to the
844 client library and to the user interface.
846 * Implemented the UMODE command to the server.
848 * The server now sends UNKNOWN_COMMAND error status if client sends
849 unknown command. Affected file silcd/command.c.
851 * All server commands now handle the command identifier the right
852 way when sending the command reply to the client. The client can
853 use to identify the command replies with the identifier.
855 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Added silc_server_get_client_route to resolve the route to
858 the client indicated by the client ID. Affected file is
861 * Added silc_server_relay_packet as general function to relay
862 packet to arbitrary destination. This deprecates functions
863 like _send_private_message_key, _relay_notify etc. Affected
864 file is silcd/packet_send.[ch].
866 Removed silc_server_send_key_agreement,
867 silc_server_send_private_message_key and
868 silc_server_packet_relay_notify functions from the file
869 silcd/packet_send.[ch].
873 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
874 server. Affected file silcd/packet_receive.[ch].
876 * Implemented the KILL command to the client. Implemented the
877 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
878 Affected files lib/silcclient/command[_reply].c and
879 lib/silcclient/client_notify.c. Implemented the KILL notify
880 printing in the user inteface.
882 * Fixed a lot silc_parse_nick memory leaks from the client
883 library in the file lib/silcclient/command.c.
885 * Changed the silc_server_send_notify_on_channels's `sender'
886 argument from SilcSocketConnection to SilcClientEntry to
887 check the sender as entry and not as connection object and not
888 to send to the client provided as argument. The affected file
889 is silcd/packet_send.[ch].
891 * The notify packets that are destined directly to the client used
892 to not to be processed by the server. Now changed that and the
893 server processes all notify packets. After relaying the packet
894 to the client the notify packet is processed in the server.
896 * The silc_server_free_client_data now checks whether there is
897 pending outgoing traffic for the client and purges the data to
898 the network before removing the client entry.
900 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
903 an client is killed from the SILC Network. Updated the protocol
906 Added new function silc_server_send_notify_killed to the
907 silcd/packet_send.[ch].
909 * Added function silc_server_packet_relay_notify to relay notify
910 packets that are destined directly to a client. In this case
911 the server does not process the notify packets but merely relays
912 it to the client. Affected file silcd/packet_send.[ch].
914 Added also silc_server_packet_process_relay_notify to check
915 whereto relay the notify. Affected file is
916 silcd/packet_receive.[ch].
918 * Implemented the KILL command to the server.
922 * Added the backup schema desgined last fall to the protocol
923 specs for everyone to see. The specification is in the
924 *-spec-xx.txt draft and the packet type definitions for the
925 backup routers is in *-pp-xx.txt draft. Thusly, added also
926 new packet type SILC_PACKET_CELL_ROUTERS.
928 * A big security problem in the implementation discovered. The
929 signoff of an client did not cause new channel key generation
930 which it of course should've done. The channel keys must be
931 always re-generated when client leaves (or signoffs) the channel.
932 The silc_server_remove_from_channels funtion now handles
933 the channel key re-generation.
935 * Added `sender' argument to the silc_server_send_notify_on_channels
936 to not to send the client provided as argument. Affected file
937 silcd/packet_send.[ch].
939 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Implemented OPER and SILCOPER commands into the server and
944 * Added silc_auth_verify and silc_auth_verify_data to verify
945 the authentication directly from the authentication payload.
946 It supports verifying both passphrase and public key based
947 authentication. Affected file lib/silccore/silcauth.[ch].
949 * Added `hash' field to the SilcIDListData structure. It is the
950 hash negotiated in the SKE protocol. Affected file is
953 * Slight redesigning of the SilcAuthPayload handling routines.
954 Do not send SilcPKCS but SilcPublicKey as argument.
956 * Implemented the public key authentication support to the
957 serverconfig. The public key is loaded from the provided path
958 and saved as authentication data to void * pointer. Thus,
959 changed the unsigned char *auth_data to void *auth_data;
961 * Fixed SHUTDOWN command to send the reply before the server
962 is shutdown. :) Affected file silcd/command.c.
964 * Fixed fatal bug in CONNECT command. The hostname was invalid
965 memory and server crashed. Affected file silcd/command.c.
967 * Fixed fatal bug in CLOSE command. The server_entry became
968 invalid but was referenced later in the command. Affected file
971 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Fixed fatal bug in failure packet handling. Server ignored
974 the failure and thus crashed when it came.
978 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
981 that the command may be executed only once in (about) 2 seconds.
982 The old SILC_CF_LAG flag is same but allows command bursts up
983 to five before limiting.
985 Added the support for CF_LAG and CF_LAG_STRICT flags to the
986 server code. Various commands now includes the CF_LAG_STRICT
987 flag to disallow any kind of miss-use of the command.
989 * Fixed the silc_buffer_unformat to not to allocate any data
990 if the length of the data is zero. It used to allocate the
991 length + 1. Affected file lib/silcutil/silcbuffmt.c.
993 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Changed the format of AdminConnection configuration section
996 in the server. Added username of the admin to the format.
997 Affected files silcd/serverconfig.[ch].
999 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1000 to return admin configuration data by host, username and/or
1003 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Implemented WHOWAS command to the server. Added the functions:
1007 silc_server_command_whowas_parse,
1008 silc_server_command_whowas_send_reply,
1009 silc_server_command_whowas_from_client and
1010 silc_server_command_whowas_from_server
1012 * Added <Client ID> argument to the WHOWAS command reply. Updated
1013 the protocol specs accordingly.
1015 * Implemented WHOWAS command and command_reply to the client
1018 Implemented the WHOWAS printing on the user interface.
1020 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Added new argument to the WHOWAS command reply, the real name.
1023 It is an optional argument. Updated the protocol specs.
1025 * Added SilcIDCacheDestructor callback that is registered when
1026 the SilcIDCache is allocated. The callback is called when
1027 an cache entry in the ID Cache expires, or is purged from the
1028 cache. Added into lib/silccore/idcache.[ch].
1030 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1031 to destruct the client entries when the cache entry expires.
1032 Other ID Cache's in server and in the client library ignores
1035 * If the ID Cache entry's `expire' field is zero then the entry
1036 never expires. Added boolean `expire' argument to the
1037 silc_idcache_add function in the lib/silccore/idcache.[ch].
1038 If it is TRUE the default expiry value is used.
1040 * Added silc_server_free_client_data_timeout that is registered
1041 when client disconnects. By default for 5 minutes we preserve
1042 the client entry for history - for WHOWAS command.
1044 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Added support to the server to enforce that commands are not
1047 executed more than once in 2 seconds. If server receives
1048 commands from client more frequently, timeout is registered
1049 to process the commands. Affected file silcd/command.c.
1050 Added new function silc_server_command_process_timeout.
1052 * Changed NICK_NOTIFY handling in client library to check that
1053 if the client's nickname was changed, so there is no need to
1054 resolve anything from the server.
1056 * Removed error printing from the WHOIS and IDENTIFY commands.
1057 If error occurs then it is ignored silently in the client library.
1058 The application, however, may map the received error to
1059 human readable error string. The application currently maps
1060 the NO_SUCH_NICKNAME error to string.
1062 * Made the command status message public to the application. Moved
1063 them from lib/silcclient/command_reply.c to
1064 lib/silcclient/command_reply.h. The application can map the
1065 received command status to the string with the
1066 silc_client_command_status_message function.
1068 * Added check to the server to check that client's ID is same
1069 as the Source ID in the packet the client sent. They must
1072 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Added dist-bzip hook to the Makefile.am to make bzip2
1075 compressed distributions.
1077 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Server now enforces the maximum length for the nickname and
1080 the channel as protocol specification dictates. 128 bytes for
1081 nickname and 256 bytes for channel name.
1083 * Moved the WHOIS printing to the application. The client libary
1084 does not print out the WHOIS information anymore, the application
1085 must do it. Renamed silc_client_command_reply_whois_print to
1086 the silc_client_command_reply_whois_save.
1088 The client's idle time is also sent to the application now, and
1089 the idle is shown on screen.
1091 * Added silc_client_command_reply_identify_save to save the
1092 received IDENTIFY entries.
1094 * Do not check for channel private keys in message sending and
1095 reception if the channel does not have the PRIVKEY mode set.
1096 Affected file lib/silclient/client_channel.c.
1098 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1101 just surfaced after chaning the JOIN procedure.
1103 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Added silc_client_get_clients_by_list to get client entries
1106 from Client ID list, that is returned for example by JOIN
1107 and USERS command replies. The application should use this
1108 function for example when JOIN command reply is received to
1109 resolve the clients already on the channel (library does not
1110 do that anymore as USERS command reply is not used in the JOIN
1111 procedure anymore). Affected files lib/silcclient/silcapi.h and
1112 lib/silcclient/idlist.c.
1114 * JOIN command reply and USERS command reply returns now SilcBuffer
1115 pointers instead of unsigned char pointers when returning
1116 the client list and mode list.
1118 * Added <Client ID> argument to the JOIN command reply, mainly
1119 for the server to identify for which client the command was
1120 originally sent. Updated protocol specs accordingly.
1122 * Added SilcDlist private_key pointer to the SilcChannelEntry
1123 in the client to support the channel private keys. Affected
1124 file is lib/silcclient/idlist.h.
1126 * Added SilcChannelPrivateKey argument to the function
1127 silc_client_send_channel_message so that application can choose
1128 to use specific private ke if it wants to. If it is not provided,
1129 the normal channel key is used, unless private keys are set.
1130 In this case the first (key that was added first) is used
1131 as the encryption key.
1133 * Implemented the support for channel private key handling.
1134 Implemented the following functions:
1136 silc_client_add_channel_private_key,
1137 silc_client_del_channel_private_keys,
1138 silc_client_del_channel_private_key,
1139 silc_client_list_channel_private_keys and
1140 silc_client_free_channel_private_keys
1142 Affected file lib/silcclient/client_channel.c.
1144 * Added the support for the private keys in the channel message
1145 sending and encryption and in the message reception and
1146 decryption. Affected funtions are
1147 silc_client_send_channel_message and silc_client_channel_message.
1149 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Added SKE's key verify callback to the client library's
1152 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1154 * Removed the statement that server (or router) must send USERS
1155 command reply when joining to the channel so that the client
1156 knows who are on the channel. Instead, the client list and
1157 client's mode list is now sent in the JOIN command reply to the
1158 client who joined channel. This is better solution.
1160 * Added function silc_server_get_users_on_channel and function
1161 silc_server_save_users_on_channel to the silcd/server.[ch].
1163 * Removed function silc_server_command_send_users from the
1166 * Do not show topic on the client library anymore. The topic is
1167 sent in the command reply notify to the application and the
1168 application must show the topic now.
1170 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Added client searching by nickname hash into the IDENTIFY and
1173 WHOIS commands in the server as they were clearly missing from
1174 them. Affected file is silcd/command.c.
1176 * Fixed a bug in private message receiving in the client library.
1177 The remote ID was freed and it wasn't supposed, now it is
1180 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Minor fix to the channel payload; allocate the data area, as it
1183 needs to be of specific length.
1185 * If the key agreement port is zero then the operating
1186 system will define the bound port. Affected files are
1187 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1189 * Added new function silc_channel_payload_decrypt into the file
1190 lib/silccore/silcchannel.[ch].
1192 * Moved the channel message etc, check from silc_packet_decrypt
1193 to applications. The library calls now a generic
1194 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1195 when the packet is either normal or special. This was done to
1196 allow more wide range of checking that was not allowed when
1197 the code was in library. Now applications can do virtually any
1198 checks to the packet and return to the library the decision how
1199 the packet should be processed. Affected files are
1200 lib/silccore/silcpacket.[ch].
1202 Added silc_server_packet_decrypt_check to the server and
1203 silc_client_packet_decrypt_check to the client library.
1205 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1206 to send with specified source and destination information.
1208 * Channel message delivery between routers was broken after the
1209 channel key distribution was fixed earlier. The channel key
1210 was used be to distributed to other routers as well which is not
1211 allowed by the protocol. Now this is fixed and channel keys
1212 really are cell specific and the channel message delivery between
1213 routers comply with the protocol specification.
1215 * Fixed various commands in server to check also the global list
1216 for the channel entry and not just the local list. The affected
1217 file silcd/command.c.
1219 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Added assert()s to buffer formatting and unformatting routines
1222 to assert (if --enable-debug) when error occurs. Affected
1223 file: lib/silcutil/silcbuffmt.c.
1225 * Changed to auto-reconnect to check whether the remote host is
1226 router and register the re-connect timeout if it is. It used
1227 to check that whether we are normal server, but router must do
1228 auto-reconnect with another router as well. Affected file
1231 * Removed the [<key len>] option from CMODE command as the cipher
1232 name decides the key length, nowadays. See the defined ciphers
1233 from the protocol specification.
1235 * Added [<hmac>] option to the CMODE command to define the HMAC
1236 for the channel. Added SILC_CMODE_HMAC channel mode.
1238 * Added [<hmac>] option for the JOIN command so that user can
1239 select which HMAC is used to compute the MACs of the channel
1242 * Added Hmac field to the Channel Message Payload. The integrity
1243 of plaintext channel messages are now protected by computing
1244 MAC of the message and attaching the MAC to the payload. The
1245 MAC is encrypted. Now, it is clear that this causes some
1246 overhead to the size of the packet but rationale for this is that
1247 now the receiver can verify whether the channel message decrypted
1248 correctly and also when private keys are set for the channel the
1249 receiver can decrypt the packet with several keys and check from
1250 the MAC which key decrypted the message correctly.
1252 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1253 lib/silccrypt/silccipher.[ch].
1255 * Added silc_hash_len to return the digest length into the
1256 lib/silcrypt/silchash.[ch].
1258 * Rewrote parts of Silc Channel Payload interface in the
1259 lib/silccore/silcchannel.[ch]. The encode function now also
1260 encrypts the packet and parse function decrypts it.
1262 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Fixed a minor formatting bug in the SKE's key material processing.
1265 It actually might have processed the keys wrong way resulting
1268 * Redefined the mandatory HMAC algorithms and added new algorithms.
1269 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1270 and hmac-md5 truncated to 96 bits. The mandatory is now
1271 hmac-sha1-96. Rest are optional (including the one that used
1272 to be mandatory). Rationale for this is that the truncated HMAC
1273 length is sufficient from security point of view and can actually
1274 make the attack against the HMAC harder. Also, the truncated
1275 HMAC causes less overhead to the packets. See the RFC2104 for
1278 * Added new [hmac] configuration section. The SKE used to use
1279 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1280 is of course wrong. The official names that must be proposed in
1281 the SKE are the ones defined in the protocol specification
1282 (hmac-sha1-96 for example). The user can configure any hmac
1283 using any hash function configured in the [hash] section. At
1284 least, the mandatory must be configured.
1286 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1288 * Added HMAC list to the SKE proposal list. It has now both
1289 hash algorithm list and HMAC list. This makes the protocol
1290 incompatible with previous versions. The SKE now seems to work
1291 the way it is supposed to work, for the first time actually.
1293 * Defined plain Hash algorithms to the protocol specification.
1296 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Implemented support for key agreement packets into the server.
1299 Added functions silc_server_key_agreement and
1300 silc_server_send_key_agreement. Other than these functions,
1301 server has nothing to do with this packet.
1303 * Added support for private message key packets into the server.
1304 Added functions silc_server_private_message_key and
1305 silc_server_send_private_message_key.
1309 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1310 called in the protocol's final callback instead in the END
1311 protocol state. This makes a little more sense and in the same
1312 time in client we can use the same protocol routines for normal
1313 key exchange and to key agreement packet handling as well.
1315 * Added to both client's and server's KE protocol context the
1316 SilcSKEKeyMaterial pointer to save the key material. We will
1317 bring the key material to the protocol's final callback by doing
1318 this. The final callback must free the key material.
1320 * Added SKE's packet_send callback into client's KE protocol
1321 context so that the caller can choose what packet sending function
1322 is used. This way we can use different packet sending when
1323 doing normal SKE when doing key agreement packet handling (in
1324 the key agreement packet handling we do not want to encrypt
1327 * Implemented the responder side of the key agreement routines
1328 in the client. The client can now bind to specified port and
1329 accept incoming key negotiation. The key material is passed
1330 to the application after the protocol is over.
1332 * Implemented the processing of incoming Key Agreement packet
1333 in the client. Added function silc_client_key_agreement to
1336 * Implemented the intiator side of the key agreement routines
1337 in the client. The client can now initiate key agreement with
1338 another remote client. The key material is passed to the
1339 application after the protocol is over.
1341 * Created client_keyagr.c to include all the key agreement
1344 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1345 SILC_TASK_CALLBACK except that it is not static.
1347 * Created client_notify.c and moved the Notify packet handling
1348 from the client.[ch] into that file.
1350 * Created client_prvmsg.c and moved all private message and
1351 private message key routines from the client.[ch] into that file.
1353 * Create client_channel.c and moved all channel message and
1354 channel private key routines from the client.[ch] into that file.
1356 * Changed silc_client_get_client_by_id_resolve to resolve with
1357 WHOIS command instead of IDENTIFY command, in the file
1358 lib/silclient/idlist.c.
1360 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Implemented the SKE's responder side to the Client library.
1364 * When FAILURE is received to the protocol do not trust it
1365 blindly. Register a timeout to wait whether the remote closes
1366 the connection as it should do it, only after that process the
1367 actual failure. This was changed to both client and server.
1369 * Added client_internal.h to include some of the structures
1370 there instead of client.h in lib/silcclient/.
1372 * Added function silc_task_unregister_by_callback to unregister
1373 timeouts by the callback function.
1375 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Some "Incomplete WHOIS info" errors has been appearing on the
1378 log files. Took away the entry->userinfo check from WHOIS
1379 reply sending. The entry->userinfo is now " " if client did not
1380 provide one. I thought this was fixed earlier but something
1381 is wrong still. Let's see if the error still appears.
1383 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Fixed a minor bug in the login when the channel key is
1386 re-generated in the server. It used to generate the key in
1387 wrong order and thus caused problems in the channel traffic.
1389 * Fixed a minor bug in channel key distsribution after
1390 KICK command. The key was not sent to the router even though
1393 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Added silc_ske_process_key_material_data as generic routine
1396 to process any key material as the SILC protocol dictates. The
1397 function is used by the actual SKE library but can be used by
1398 applications as well. This relates to the private message keys
1399 and the channel private keys since they must be processed the
1400 same way the normal SILC session keys. The protocol dictates
1401 this. Affected files: lib/silcske/silcske.[ch].
1403 Added also silc_ske_free_key_material to free the
1404 SilcSKEKeyMaterial structure.
1406 * Defined silc_cipher_set_key function to set the key for
1407 cipher without using the object's method function. The affected
1408 files: lib/silccrypt/silccipher.[ch].
1410 * Implemented silc silc_client_add_private_message_key,
1411 silc_client_add_private_message_key_ske,
1412 silc_client_del_private_message_key,
1413 silc_client_list_private_message_keys and
1414 silc_client_free_private_message_keys functions in the
1417 Added functions silc_client_send_private_message_key to send
1418 the Private Message Key payload and silc_client_private_message_key
1419 to handle incoming Private Message Key payload.
1421 * Added Cipher field to the Private Message Key payload to set
1422 the cipher to be used. If ignored, the default cipher defined
1423 in the SILC protocol (aes-256-cbc) is used.
1425 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1427 * Removed lib/silcclient/ops.h file.
1429 Redefined parts of the SILC Client Library API. Created new
1430 file silcapi.h that deprecates the ops.h file and defines the
1431 published Client Library API. Defined also private message key
1432 API and channel private key API into the file.
1434 This is the file that the application must include from the
1435 SILC Client Library. Other files need not be included by
1436 the application anymore.
1438 * Added new key_agreement client operation callback and also
1439 defined the Key Agreement library API for the application.
1441 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1444 is used by clients to request key negotiation between another
1445 client in the SILC network. If the negotiation is started it
1446 is performed using the SKE protocol. The result of the
1447 negotiation, the secret key material, can be used for example
1448 as private message key.
1450 Implemented the Key Agreement payload into the files
1451 lib/silccore/silauth.[ch].
1453 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Redefined ciphers for the SILC protocol. Added some new ciphers
1456 and defined the key lengths for the algorithms. Changed the
1457 code accordingly. The default key length is now 256 bits.
1459 * Fixed SKE key distribution function silc_ske_process_key_material
1460 when the key length is more than 128 bits. The default key
1461 length in SILC is now 256 bits.
1463 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1464 to indicate unsupported algorithm.
1466 * Renamed rijndael.c to aes.c and all functions as well.
1468 * Fixed a long standing channel key setting bug in client library.
1469 Weird that it has never surfaced before.
1471 * Fixed bug in channel deletion. If the entire channel is removed
1472 then it must also delete the references of the channel entry
1473 from the client's channel list as the client's channel entry and
1474 the channel's client entry share same memory.
1476 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Implemented CONNECT and SHUTDOWN commands in the client.
1480 * Implemented CLOSE command to the client.
1482 * Added the function silc_idlist_find_server_by_name into the
1483 files silcd/idlist.[ch].
1485 Added the function silc_idlist_find_server_by_conn into the
1486 files silcd/idlist.[ch].
1488 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * DIE command was renamed to SHUTDOWN. Updated the both code
1493 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1494 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1496 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1499 * Added function silc_server_create_connection function to create
1500 connection to remote router. My server implementation actually
1501 does not allow router to connect to normal server (it expects
1502 that normal server always initiates the connection to the router)
1503 so the CONNECT command is only good for connecting to another
1506 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1509 or some other client was kicked from the channel.
1511 Implemented the handling of the notify type to both client
1514 Implemented silc_server_send_notify_kicked to send the KICKED
1515 notify. It is used to send it to the server's primary router.
1517 * Implemented the KICK command into server and client.
1519 * Added `query' argument to the silc_idlist_get_client function
1520 to indicate whether to query the client from server or not if
1523 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1524 to indicate that the client is not channel founder.
1528 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Removed the rng context from SilcPacketContext structure and
1531 changed that the packet routine uses the Global RNG API.
1533 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Added support for quit message that client can "leave" on the
1536 channel when it quits the SILC. It is ditributed inside the
1537 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1539 Added silc_server_free_client_data that will take the
1540 signoff message as argument.
1542 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1544 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Updated parts of the protocol specification to keep it up
1549 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1552 payloads in one packet.
1554 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1555 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1556 use now the new List flag.
1558 * Also deprecated the following packet types: REPLACE_ID,
1559 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1561 * Added list support for Notify packet in server.
1563 * Added silc_server_send_notify_channel_change to send the
1564 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1565 the silc_server_send_replace_id.
1567 * Added silc_server_send_notify_nick_change to send the
1568 NICK_CHANGE notify type. Deprecates the function
1569 silc_server_send_replace_id.
1571 * Added silc_server_send_notify_join to send the JOIN notify type.
1572 Deprecates the function silc_server_send_new_channel_user.
1574 * Added silc_server_send_notify_leave to send LEAVE notify type.
1575 Deprecates the function silc_server_send_remove_channel_user.
1577 * Added silc_server_send_notify_cmode and
1578 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1579 types. Deprecates the silc_server_send_set_mode function.
1581 * Added SERVER_SIGNOFF notify type to indicate that server has
1582 quit. This means that all clients on the channel from that
1583 server will drop. This can be also used when netsplit happens.
1585 Deprecated REMOVE_ID packet type since it is not needed anymore
1588 Added silc_server_send_notify_server_signoff to send the
1589 SERVER_SIGNOFF notify type. Deprecates the function
1590 silc_server_send_remove_id.
1592 Added also silc_server_send_notify_signoff to send the
1593 SIGNOFF notify type.
1595 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1596 SILC protocol from this day on. Changed the protocol
1597 specification as well.
1599 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1600 notify type. It is used between routers to notify about
1601 topic changes on a channel.
1603 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1606 * Partly updated the protocol specification to comply with the
1607 changes now made. It is still though a bit outdated.
1609 * The JOIN notify type now takes one extra argument <Channel ID>.
1610 The packet used to be destined to the channel but now the
1611 JOIN type may be sent as list thus it is impossible to
1612 destine it to any specific channel. By adding this argument
1613 it is again possible.
1615 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Added CREDITS file. The CHANGES and CREDITS file will appear
1618 in the distribution as well.
1620 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1623 types in the server's silcd/packet_receive.c.
1625 * Implemented CMODE and CUMODE to work in router environment.
1627 * Fixed minor encoding and decoding buglet from the
1628 lib/silccore/silcmode.c.
1630 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1633 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1635 * Changed all SilcConfigServer* and silc_config_server* to
1636 SilcServerConfig* and silc_server_config*, respectively.
1639 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Associated the ID (client or server ID) to the Authentication
1642 Payload to avoid any possibility of forging. Updated the
1643 protocol specification and the code accordingly.
1645 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * The RSA key length is now save to the RsaKey context in the
1648 key generation process in lib/silccrypt/rsa.c. The key length
1649 is now used to figure out the maximum size of the block allowed
1650 to be encrypted/signed.
1652 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1653 is equivalent to the silc_mp_mp2bin but does not allocate any
1656 * Changed silc_mp_mp2bin API to take length argument. If it is
1657 non-zero then the buffer is allocated that large. If zero, then
1658 the size is approximated using silc_mp_sizeinbase, which however
1661 * Created Global RNG API which is global RNG that application can
1662 initialize. After initializing, any routine anywhere in the
1663 code (including library) can use RNG without allocating a new
1664 RNG object. This was done to allow this sort of use of the
1665 RNG in code that has no chance to allocate RNG object. All
1666 applications currently allocate this and many routines in the
1667 library use this. Affected file lib/silccrypt/silcrng.[ch].
1669 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1670 it to use the Global RNG API.
1672 * Defined Authentication Payload into protocol specification that
1673 is used during SILC session to authenticate entities. It is
1674 used for example by client to authenticate itself to the server
1675 to obtain server operator privileges.
1677 Implemented this payload into the lib/silccore/silcauth.[ch].
1678 Implemented also routines for public key based authentication
1679 as the new protocol specification dictates.
1681 Moved definitions of different authentication methods from
1682 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1684 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1685 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1686 silc_pkcs_verify_with_hash functions into the file
1687 lib/silccrypt/silcpkcs.[ch].
1689 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * The client entry's userinfo pointer must be always valid.
1692 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1693 will fail since it requires the userinfo. Now, the userinfo
1694 is allocated as "" if actual userinfo does not exist. Actually,
1695 it must exist and it is totally Ok to drop client connections
1696 that does not announce the userinfo. However, we will make
1697 this workaround for now.
1699 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1700 to return the remote port by socket.
1702 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1705 SILC_SERVER_PENDING_EXEC and added an new macro
1706 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1707 data or when error occurs while processing the pending command.
1709 Added new argument `destructor' into silc_server_command_pending
1710 and to the SilcServerCommandPending object. This destructor is
1711 now called after calling the pending callback or if error occurs
1712 immediately. If error occurs the actual pending callback won't
1713 be called at all - only the destructor. The destructor may be
1714 NULL if destructor is not needed.
1716 All this applies for client library code as well. Similar
1717 changes were made there as well for the pending commands.
1719 In the client, the application must now allocate the
1720 SilcClientCommandContext with the silc_client_command_alloc
1723 * Added reference counter to the SilcServerCommandContext. Added
1724 function silc_server_command_alloc and silc_server_command_dup
1727 Same type of functions added to the client library for the same
1730 * Removed the cmd_ident from IDListData away since it is now
1731 global for all connections. It is the command identifier used
1732 in command sending and with pending commands. The affected file
1735 * Added reference counter to the SilcSocketConnection objecet to
1736 indicate the usage count of the object. The object won't be
1737 freed untill the reference counter hits zero. Currently only
1738 server uses this, and client ignores it. The client must be
1739 set to use this too later. The affected files are
1740 lib/silccore/silcsockconn.[ch]. Added also the function
1741 silc_socket_dup to increase the reference counter.
1743 This was mainly added because it is possible that the socket
1744 is removed underneath of pending command or other async
1745 operation. Now it won't be free'd and proper DISCONNECTING
1746 flags, etc. can be set to avoid sending data to connection that
1747 is not valid anymore.
1749 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1750 the connection. After that it sets SILC_SET_DISCONNECTED.
1751 It is, however, possible that the socket data is not still freed.
1752 The silc_server_packet_process now checks that data is not
1753 read or written to connection that is DISCONNECTED. The socket
1754 get's freed when the reference counter hits zero.
1756 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Changed the client operation API: channel_message operation's
1759 `sender' is now the client entry of the sender, not the nickname
1760 and the `channel' is the channel entry, not the channel name.
1762 In the private_message operation the `sender' is now also the
1763 client entry of the sender not the nickname.
1765 Affected file is lib/silcclient/ops.h and all applications
1766 using the client operations.
1768 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Moved the calling of ops->connect() from connect_to_server_final
1771 into receive_new_id functin since that is the point when the
1772 client is actually allowed to send traffic to network. The
1773 affected file is lib/silcclient/client.c.
1775 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1778 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1779 (if needs broadcasting) instead of broadcasting the packets one
1780 by one which would make a burst in the network traffic.
1782 * Added `broadcast' argument to the functions in silcd/server.[ch]
1783 silc_server_create_new_channel[_with_id] to indicate whether
1784 to send New Channel packet to primary router.
1786 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Added new function into the silcd/server.[ch] files:
1789 silc_server_create_new_channel_with_id to create new channel with
1790 already existing Channel ID.
1792 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1793 lib/silccore/silcpacket.h. This packet is used t send list of
1794 Set Mode payloads inside one packet. Server uses this to set
1795 the modes for the channels and clients on those channels, that it
1796 announced to the router when it connected to it. The protocol
1797 specification has been updated accordingly.
1799 * The silc_server_new_channel did not handle the packet coming
1800 from normal server as it normally does not send that. However,
1801 when it announces its channels it does send it. Implemented
1802 the support for that.
1804 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1805 into the file lib/silccore/id.h.
1807 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Fixed memory leaks in the functions silc_idlist_del_client,
1810 silc_idlist_del_channel and silc_idlist_del_server in the file
1811 silcd/idlist.c. All of those leaked like a sieve.
1813 * Fixed some small memory leaks in the client's function
1814 silc_client_notify_by_server.
1816 * Added functions into silcd/server.c: silc_server_announce_clients,
1817 silc_server_announce_channels and silc_server_announce_server.
1818 These functions are used by normal and router server to announce
1819 to its primary router about clients, channels and servers (when
1820 router) that we own. This is done after we've connected to the
1823 These functions effectively implements the following packet types:
1824 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1825 and SILC_PACKET_NEW_ID_LIST.
1827 * Added new functions into the silcd/packet_receive.[ch]:
1828 silc_server_new_id_list, silc_server_new_channel_list and
1829 silc_server_new_channel_user_list to handle the incoming
1830 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1832 * Added support of changing Channel ID in the function
1833 silc_server_replace_id. If the server that announces a channel
1834 to the router already exists in the router (with same name but
1835 with different Channel ID), router is responsible to send
1836 Replace ID packet to the server and force the server to change
1837 the Channel ID to the one router has.
1839 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1840 client that the Channel ID has been changed by the router. The
1841 normal server sends this to the client. Client must start using
1842 the new Channel ID as the channel's ID.
1844 Implemented handling of this new type into lib/silcclient/client.c
1845 into the function silc_client_notify_by_server.
1847 * Added new function silc_idlist_replace_channel_id into the files
1848 silcd/idlist.[ch] to replace the Channel ID.
1850 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Call silc_server_command_identify_check always when processing
1853 the IDENTIFY command in silcd/command.c
1855 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1858 send keepalive packets. The packet can be sent by clients,
1859 servers and routers.
1861 Added function silc_socket_set_heartbeat into the file
1862 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1863 If not set, the heartbeat is not performed. The actual
1864 heartbeat is implemented in the low level socket connection
1865 library. However, application is responsible of actually
1868 Added silc_server_send_heartbeat to send the actual heartbeat
1869 packet into silcd/packet_send.[ch]. Server now performs
1870 keepalive with all connections.
1872 * Added silc_task_get_first function into lib/silcutil/silctask.c
1873 to return the timeout task with shortest timeout. There was a bug
1874 in task unregistration that caused problems. TODO has been
1875 updated to include that task system must be rewritten.
1877 * The client library will now resolve the client information when
1878 receiving JOIN notify from server for client that we know but
1879 have incomplete information.
1881 * Rewrote parts of silc_server_remove_from_channels and
1882 silc_server_remove_from_one_channel as they did not remove the
1883 channel in some circumstances even though they should've.
1885 * Encryption problem encountered in server:
1887 The LEAVE command used to send the Channel Key packet to the
1888 router immediately after generating it. However, the code
1889 had earlier sent Remove Channel user packet but not immediately,
1890 ie. it was put to queue. The order of packets in the router
1891 was that Channel Key packet was first and Remove Channel User
1892 packet was second, even though they were encrypted in the
1893 reverse order. For this reason, MAC check failed. Now, this
1894 is fixed by not sending the Channel Key packet immediately but
1895 putting it to queue. However, this is more fundamental problem:
1896 packets that are in queue should actually not be encrypted
1897 because packets that are sent immediately gets encrypted
1898 actually with wrong IV (and thus MAC check fails). So, packets
1899 that are in queue should be encrypted when they are sent to
1900 the wire and not when they put to the queue.
1902 However, the problem is that the current system has not been
1903 designed to work that way. Instead, the packet is encrypted
1904 as soon as possible and left to the queue. The queue is then
1905 just purged into wire. There won't be any fixes for this
1906 any time soon. So, the current semantic for packet sending
1909 o If you send packet to remote host and do not force the send
1910 (the packet will be in queue) then all subsequent packets to the
1911 same remote host must also be put to the queue. Only after the
1912 queue has been purged is it safe again to force the packet
1915 o If you send all packets immediately then it safe to send
1916 any of subsequent packets through the queue, however, after
1917 the first packet is put to queue then any subsequent packets
1918 must also be put to the queue.
1920 Follow these rules and everything works fine.
1922 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Added new function silc_server_remove_clients_by_server to
1925 remove all client entries from ID list when the server connection
1926 is lost. In this case it is also important to invalidate all
1927 client entires as they hold the invalid server entry. This
1928 fixes fatal bug when server has lost connection and will reconnect
1931 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Made some sanity checks to silc_server_daemonise like to check
1934 whether the requested user and group actually exists.
1936 * Added sanity check to SKE's silc_ske_responder_finish to check
1937 that the public and private key actually is valid.
1939 * Invalidate the client's nickname when receiving Replace ID
1940 packet and the Client ID is being replaced. This means that the
1941 server will query the nickname if someone needs it (client)
1944 * Sort the ID Cache in client library when the ID Cache data
1945 has changed (needs sorting).
1947 * Do not allow for SILC client to create several connections to
1948 several servers. The client does not support windows right now
1949 and generating multiple connections causes weird behaviour.
1951 Irssi-silc client does support windows and can handle several
1952 connections without problems, see: www.irssi.org and SILC plugin.
1954 * Fixed some places where client was added to the IDList. The
1955 rule of thumb is following (in order to get everything right):
1956 If the client is directly connected local client then the
1957 `connection' argument must be set and `router' argument must be
1958 NULL to silc_idlist_add_client function. If the client is not
1959 directly connected client then the `router' argument must
1960 bet set and the `connection' argument must be NULL to the
1961 silc_idlist_add_client function.
1963 * The funtion silc_server_packet_send_local_channel actually did
1964 not check whether the client was locally connected or not. It
1965 does that now. Fixed a bug related to LEAVE command.
1967 * Fixed Remove Channel User payload parsing bug in server's
1968 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1970 * The server's silc_server_save_channel_key now checks also the
1971 global ID list for the channel as it might not be in the local
1972 list. Fixed a bug related to LEAVE command.
1974 * Is this the end of the [<unknown>] buglet that has been lurking
1975 around for a long time? A little for loop fix in server's
1976 silc_server_command_whois_parse that is used by both IDENTIFY
1977 and WHOIS command. At least, this was a clear bug and a cause
1978 of one type of [<unknown>] buglet.
1980 * WHOIS and IDENTIFY commands call the function
1981 silc_server_command_[whois/identify]_check function even if
1982 we are not router server.
1984 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Added --with-gmp configuration option. If set the GMP
1987 is always compiled in the SILC source tree. If not set then
1988 it is checked whether the system has the GMP3 installed. If
1989 it has then the GMP won't be compiled (the system's headers
1990 and library is used), if it doesn't have it then the GMP is
1991 compiled in the SILC source tree.
1993 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Changed RSA private exponent generation to what PKCS #1
1996 suggests. We try to find the smallest possible d by doing
1997 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1998 not security fix but optimization.
2000 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Added new config entry [Identity] to fork the server and run
2003 it as specific user and group. A patch from Bostik.
2005 * Imported Dotconf configuration library into lib/dotconf.
2006 This will be used to create the SILC configuration files later.
2007 It will appear in the distsribution after this commit.
2009 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * A big code auditing weekend happening. Auditing code for
2012 obvious mistakes, bugs and errors. Also, removing any code
2015 Removed files for being obsolete:
2017 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2018 inline in the file lib/silcutil/silcbuffer.h)
2020 o lib/silcutil/silcbufutil.c (the header has inline versions)
2022 Changed code to fix possible error conditions:
2024 o The buffer formatting routines now check that the destination
2025 buffer really has enough space to add the data. This applies for
2026 both buffer formatting and unformatting
2027 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2028 unformatting was changed to accomodate following rules:
2029 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2030 sent to the function while XXX_*STRING will not allocate or copy
2031 the data into the buffer. Instead it sets the pointer from the
2032 buffer into the pointer sent as argument (XXX_*STRING used to
2033 require that the pointer must be allocated already). This change
2034 makes this whole thing a bit more consistent and more optimized
2035 (note that the data returned in the unformatting with XXX_*STRING
2036 must not be freed now). The routines return now -1 on error.
2038 o Tried to find all code that use buffer_format and buffer_unformat
2039 and added return value checking to prevent formatting and
2040 especially unformatting errors and possible subsequent fatal
2043 o Changed ske->x and ske->KEY to mallocated pointers in
2044 lib/silcske/silcske.h. Fixed possible data and memory leak.
2046 o Added return value checking to all *_parse* functions. Fixed
2047 many memory leaks as well.
2049 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2050 so that buffer overflows would not happen. All code now also
2051 checks the return value as it can fail.
2053 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Added reconnection support to server if the normal server looses
2056 its connection to the router (for example if router is rebooted).
2057 The server performs normal reconnection strategy implemented
2058 to the server. Affected file silcd/server.c.
2060 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Added new packet type SILC_PACKET_SET_MODE that is used to
2063 distribute the information about changed modes (for clients,
2064 channels and clients channel modes) to all routers in the
2065 network. Updated the protocol specification accordingly.
2067 Added functions into silcd/packet_send.c and
2068 silcd/packet_receive.c: silc_server_send_set_mode,
2069 silc_server_set_mode.
2071 Added new files silcmode.[ch] into lib/silccore that implements
2072 the encoding and decoding of Set Mode Payload. Added new type
2073 SilcSetModePayload. Moved the definitions of different modes
2074 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2076 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * Oops, a little mistake in server's connection authentication
2079 protocol. The protocol is not ended with FAILURE but with
2080 SUCCESS if the authentication is Ok. :) Affected file is
2083 * Implemented NICK_CHANGE notify handling in server in the file
2084 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2085 the local clients on the channel. After the changing nickname
2086 in router environment snhould work and the [<unknown>] nickname
2087 should appear no more.
2089 The silc_server_replace_id function that receives the Replace ID
2090 payload now sends the NICK_CHANGE notify type also in the file
2091 silcd/packet_receive.c
2093 * Changed WHOIS and IDENTIFY command to support the maximum amount
2094 of arguments defined in protocol specs (3328 arguments). This
2095 fixed a bug that caused problems when there were more than three
2098 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Added extra parameter, command identifier, to the
2101 silc_client_send_command so that explicit command identifier
2104 Changed that ID list routines uses specific command identifier
2105 when sending WHOIS/IDENTIFY requests to the server so that they
2106 can be identified when the reply comes back.
2108 Affected files lib/silcclient/command.[ch],
2109 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2111 * Added `sender' argument to silc_server_packet_send_to_channel
2112 to indicaet the sender who originally sent the packet to us
2113 that we are now re-sending. Ignored if NULL. Affected file
2114 silcd/packet_send.[ch].
2116 * Added some server statistics support in silcd/server_internal.h
2117 SilcServerStatistics structure and around the server code. Also
2118 send some nice statistics information when client is connecting
2121 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Fixed channel ID decoding in server's JOIN command reply in
2124 silcd/command_reply.c
2126 * Fixed braodcasting of replace ID payload to not to send it if
2127 we are standalone server in silcd/packet_receive.c.
2129 * Fixed all channel message sending routines to not to send
2130 packets to clients that has router set, since they are routed
2131 separately in the same function earlier. Affects file
2132 silcd/packet_send.c and all channel packet sending functions.
2134 * In USERS reply, res_argv[i] are not allocated, the table
2135 is allocated. Thus changed that free the table, not its
2138 * In server's whois_check and identify_check if the client is
2139 locally connected do not send any WHOIS commands - they are not
2142 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Fixed some minor bugs in client when sending WHOIS command. The
2145 arguments was in wrong order.
2147 * Removed statis function add_to_channel from server in
2148 silcd/command.c that was previously used with the joining but
2151 * Tested USERS command in router environment successfully with two
2152 routers, two servers and two clients.
2154 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Reorganized the USERS command and command reply in client library
2157 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2158 When the command is given by user we register a pending command
2159 callback that will reprocess the command after the reply has been
2160 received from the server. When reprocessing the packet we then
2161 display the information. Thus, the USERS information is displayed
2162 now in the command callback instead of in the command reply
2163 callback. The processing of the command is same as previously
2164 when server has sent the command reply in the JOINing process.
2166 * Added to USERS command in silcd/command_reply.c to join the client,
2167 we didn't use to know about, to the channel after we've created
2168 a client entry for it. Also, for clienet we did know already still
2169 check whether it is on the channel or not and add it if not.
2171 * Removed silc_server_command_join_notify as the function and its
2174 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Changed the client's pending command handling to the same as the
2177 server's pending command handling. It is also now possible to
2178 execute command reply functions from other command reply
2179 function as the function callbacks for commands and command
2180 replies are one and same. The pending commands are not static
2181 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2182 in client connection context. Thus, pending commands are server
2183 connection specific as it is convenient.
2185 Changed the function silc_client_command_pending and
2186 silc_client_command_pending_del and added new function
2187 silc_client_command_pending_check. Removed the
2188 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2191 * Added cmd_ident, current command identifier, to the client
2192 connection context in lib/silcclient/client.h to keep track on
2193 command identifiers used in command sending. Client's command reply
2194 function handling now supports the mandatory command identifiers.
2196 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2197 funtions in client to fully support pending command callbacks.
2199 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2200 as one of the arguments to the application in the command reply
2203 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2204 before first releasing SILC but came back. Now it is removed again
2205 and should come back nomore. The FORWARDED flag was used only
2206 by the JOINing procedure by forwarding the command packet to router.
2207 Now, the JOINing procedure has been changed to more generic (due
2208 to various router environment issues) and FORWARDED is not needed
2209 anymore for anything. The protocol specification is yet to be
2212 Now, removed silc_server_packet_forward from server and the flag
2213 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2215 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Renamed NAMES command to USERS command. The NAMES was named that
2218 due to historical reasons. Now it is renamed. Also, rewrote
2219 parts of the USERS command. The nickname list is not sent anymore
2220 by the server. Only Client ID and mode lists are sent in the USERS
2221 command. Changed this also to the protocol specification.
2223 The client now resolves the names and stuff after it receives
2224 the USERS list from the server when joining to the channel.
2226 * WHOIS and IDENTIFY commands has been changed to support multiple
2227 Client ID's per command. One can now search for multiple users
2228 in the network by sending only one WHOIS or IDENTIFY command.
2229 Changed the code and the protocol specifications.
2231 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2232 uses silc_server_command_whois_parse to parse the request. */
2234 * If normal server, do not parse the WHOIS and IDENTIFY requests
2235 before sending it to the router. Saves some time.
2237 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Fixed JOIN command on client library. Wrong number of arguments
2240 used to crash the client.
2242 * Added silc_server_channel_has_global function to check whether
2243 channel has global users or not.
2245 * Added silc_server_channel_has_local function to check whether channel
2246 has locally connected clients on the channel.
2248 * The silc_server_remove_from_one_channel now checks whether the
2249 channel has global users or not after given client was removed from
2250 the channel. It also checks whether the channel has local clients
2251 on the channel anymore. If it does not have then the channel entry
2252 is removed as it is not needed anymore.
2254 * The silc_server_notify now checks on JOIN notify whether the joining
2255 client is one of locally connected or global. If it is global then
2256 the channel has now global users on the channel and that is marked
2257 to the channel entry. Also, it now saves the global client to
2258 global list who is joining and JOINs it to the channel. This is
2259 for normal server, that is.
2261 Changed silc_server_send_notify_on_channel,
2262 silc_server_packet_relay_to_channel and
2263 silc_server_packet_send_to_channel check if we are normal server
2264 and client has router set (ie. global client) do not send the
2265 message to that client, as it is already routed to our router.
2267 * Implemented LEAVE notify type handling in silc_server_notify
2270 * Tested LEAVE command in router environment successfully. Tested
2271 with two routers, two servers and two clients.
2275 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2277 * Implemented SIGNOFF notify type handling in silc_server_notify
2280 * silc_server_remove_id now removes the client entry from all channels
2281 it has joined and thusly sends SIGNOFF notify type.
2283 * Rewrote the NAMES list generation in server by removing two excess
2284 loops. The lists are created now inside one loop.
2286 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * silc_server_remove_channel_user checks now also global list
2289 for channel and client.
2291 * silc_server_new_channel_user checks now both local and global
2292 list for channel and client. Fixed a bug in client id decoding.
2293 Used to decode wrong buffer.
2295 * silc_server_channel_message checks now both local and global
2296 list for channel entry.
2298 * Tested channel joining (hence JOIN) in router environment
2299 successfully. Tested with two routers, two servers and two
2302 * Tested channel message sending in router environment successfully.
2304 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Added silc_server_save_channel_key into server.[ch] to save the
2307 received channel key in Channel Key payload processing. It is
2308 also used in JOIN command reply handling.
2310 Equivalent function silc_client_save_channel_key added into
2311 client.[ch] into client library.
2313 * Changed JOIN command reply to send information whether the channel
2314 was created or not (is existing already) and the channel key
2315 payload. Changed protocol specs accordingly.
2317 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2318 the request was sent by ID and not by nickname. Crashed on
2321 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2324 now correctly save the received data.
2326 * silc_server_free_sock_user_data now notifies routers in the
2327 network about entities leaving the network.
2329 At the same time implemented functions silc_server_remove_id
2330 and silc_server_send_remove_id to receive and send REMOVE_ID
2331 packets. The packet is used to notify routers in the network
2332 about leaving entities. The ID removed will become invalid in
2335 * Added function silc_idlist_del_server into server. Removes and
2336 free's server entry from ID list.
2338 * silc_server_private_message function now checks, if we are router,
2339 that the destination ID really is valid ID, naturally.
2341 * In router when NEW_ID packet is received (for new client) the
2342 hash of the Client ID is saved in the ID Cache but the
2343 client->nickname is set to NULL, instead of putting the hash
2346 IDENTIFY command now also checks that client->nickname must be
2347 valid. If it is not if will request the data from the server who
2348 owns the client. Added new function
2349 silc_server_command_identify_check.
2351 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2352 to set the command to already allocated Command Payload.
2354 * Tested private message sending in router environment with two
2355 routers, two servers and two clients. Fixed minor bugs and now
2358 * Fixed segfault from client's NAMES command. Used to crash if
2361 * Forwarded packets must not be routed even if it is not destined
2362 to the receiver. Changed server code comply with this.
2364 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Added `require_reverse_mapping' boolean value to ServerParams
2367 structure. If TRUE (not default) the server will require that
2368 the connecting host has fully qualified domain name.
2370 If the reverse mapping is not required and hostname could not be
2371 found the IP address is used as hostname.
2373 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Implemented version string checking to both client and server.
2376 The check is incomplete currently due to the abnormal version
2377 strings used in development version of SILC.
2379 * Changed all command functions in server to use the new
2382 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Changed char *data to unsigned char *data in ID Cache system to
2385 support binary data as ID Cache data. Changed code to support
2386 binary data in lib/silccore/idcache.c.
2388 * Renamed silc_server_packet_relay_command_reply to
2389 silc_server_command_reply as it is normal packet receiving
2390 function. Rewrote the function to accept command replys for
2391 servers and not only for clients.
2393 * Mark remote router always as registered server if we are connecting
2394 to it. Otherwise, commands sent by the router to us are ignored.
2396 * All ID List find routines now returns the ID Cache Entry pointer
2397 as well if requested.
2399 * WHOIS command works now in router environment, tested with two
2400 routers, two servers and two clients.
2402 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2403 in router environment (as it is almost equivalent to WHOIS) but
2404 hasn't been tested thoroughly. Added new functions:
2406 silc_server_command_identify_parse
2407 silc_server_command_identify_send_reply
2408 silc_server_command_identify_from_client
2409 silc_server_command_identify_from_server
2411 * Disabled route cache adding because adding two different ID's with
2412 same IP replaces the old cache entry thus giving wrong route.
2413 The entry->router->connection is always the fastest route anyway
2414 so route cache may not be needed. Of course, new routes maybe
2415 established after receiving the ID when the entry->router->connection
2416 might not be anymore the most optimal.
2418 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Add route cache for received ID for fast routing.
2422 * Added silc_server_packet_route to route received packet on router
2423 that is not destined to us.
2425 * Renamed silc_server_get_route to silc_server_route_get.
2427 * Added id_string and id_string_len fields into SilcServer to
2428 include encoded ServerID for fast comparing without excess
2429 encoding of the ID's.
2431 * Cleaned up WHOIS command on server side. Added following static
2434 silc_server_command_whois_parse
2435 silc_server_command_whois_check
2436 silc_server_command_whois_send_reply
2437 silc_server_command_whois_from_client
2438 silc_server_command_whois_from_server
2440 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2441 arguments in command replies. All command functions should be
2442 updated to use this macro.
2444 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Minor typo fixes on command reply handling on server.
2448 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Added silc_server_command_add_to_channel internal routine to add
2451 the client to the channel after router has created the channel and
2452 sent command reply to the server.
2454 * Added generic silc_server_send_command to send any command from
2457 * Use static buffer with ID rendering instead of duplicating data.
2459 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Fixed a channel user mode bug when joining to a channel server gave
2462 everybody channel founder rights, oops.
2464 * We mark ourselves as the router of the incoming server connection
2465 if we are router ourselves. This way we can check in some packet
2466 sending functions whether it is locally connected server. For
2467 incoming router connections we put NULL.
2469 * For router sending packets locally means now always sending the
2470 packet cell wide; to local clients and local servers. For normal
2471 server sending packet locally means sending it to only local
2474 * Fixed the JOIN command to really work in router environment. If the
2475 channel is created it is always created by the router. Router is
2476 also responsible of making the initial joining to the channel,
2477 sending JOIN notify to the sending server and distributing
2478 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2479 does not exist server doesn't do anything else but forward the
2480 command to the router which performs everything.
2482 * Added silc_server_send_channel_key function to send the Channel Key
2485 * Added silc_server_create_channel_key to create new channel key. The
2486 channel key is now re-generated everytime someone joins or leaves
2487 a channel, as protocol dictates. Note: channel->key_len is the
2490 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2493 packet_receive.[ch] to separate packet sending and receiving
2494 routines. The server.[ch] now includes everything else including
2495 actual packet processing (writing and reading data) and other
2498 Renamed silc_server_private_message_send_internal to
2499 silc_server_send_private_message. The routine is still though
2500 used only to relay private messages as server does not send
2501 private messages itself.
2503 Renamed silc_server_new_channel to silc_server_create_new_channel
2504 and added new function sicl_server_new_channel that handles the
2505 incoming New Channel packet. Added also new sending function
2506 silc_server_send_new_channel to send New Channel Payload.
2508 * Added new function silc_server_notify to process incoming notify
2509 packet to the server/router. Server may then relay the notify
2510 to clients if needed.
2512 * Added new function silc_server_new_channel_user to process incoming
2513 New Channel User packet. Router will redistribute the packet and
2514 send JOIN notify to its local clients and locally connected servers
2515 if needed. Normal server will send JOIN notify to its local client
2516 on same channel when received this packet. Added also corresponding
2517 sending function silc_server_send_new_channel_user to sent the
2520 * Added boolean route argument to send_notif_to_channel and
2521 packet_send_to_channel functions to attempt to route the packet
2522 if it is TRUE and send only locally if it is FALSE.
2524 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * silc_server_replace_id now broadcasts the received replace ID
2527 packet if it is not broadcast packet already. The router must
2528 broadcast to inform other routers about changed ID.
2530 * Added backpointer to server's router into SilcServer context in
2531 silcd/server_internal.h.
2533 * Fixed silc_server_packet_broadcast to send correct broadcast
2536 * The channel key is now distributed to the local client as soon
2537 as it is received from the router (in router environment) so that
2538 no other packet may be sent for the channel until client has
2541 * silc_server_remove_channel_user now broadcasts the received
2542 Remove Channel User packet if it is not broadcast packet already.
2543 The router must broadcast to inform other routers about removed
2546 * Added users field into SilcPacketContext that is a reference count
2547 of the context. One can increase the reference count by calling
2548 silc_packet_context_dup which is now changed to just increase the
2549 reference count instead of duplicating the data. The reference
2550 count is decresed by calling silc_packet_context_free that will
2551 free the data after the reference count hits zero.
2553 For now on the packet context and everything allocated into it
2554 (including the raw packet from network) must be freed by calling
2555 the new silc_packet_context_free function. Added also new function
2556 silc_packet_context_alloc that must be used now to allocate the
2557 context. This also means that if a routine is asynchronous from
2558 silc_[client/server]_packet_parse_type the packet context must
2559 be duplicated by calling silc_packet_context_dup. Otherwise it
2560 gets free'd after silc_[client/server]_packet_parse_type returns.
2561 Also, one must remember that if packet is duplicated then its
2562 reference count must be decresed by calling the free function as
2563 many times as it was duplicated.
2565 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2566 from both client and server.
2568 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Made joining to a channel working in router environment.
2572 * Cleaned up JOIN command on server side and create function
2573 silc_server_command_join_channel internal routine to make the
2576 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Changed silc_command_pending list to SilcDList. Also, added
2579 `ident' field to SilcServerCommandPending structure to identify
2580 the reply and to call correct callback.
2582 Added silc_server_command_pending_check function to replace the
2583 corresnponding macro. The silc_command_pending list is not
2586 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2587 to set identifier to previously allocated Command Payload. It
2588 is used to set identifier for command when resending Command
2591 * Added silc_command_payload_encode_payload to encode Command
2592 Payload buffer from SilcCommandPayload structure.
2594 * Added silc_argument_payload_encode_payload to encode Argument
2595 payload buffer from SilcArgumentPayload structure.
2597 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Changed WHOIS command to support router connection on server side.
2600 The whois request is always sent to router unless the server is
2601 standalone server. After server has received the reply from the
2602 router will it send the reply to the client.
2604 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2605 broadcast received broadcast packet. The function is used only
2606 by router. The broadcast packet is always sent to the router's
2609 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2610 render given ID to printable string, for log files for example.
2612 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Made basic router to router connections working. At least they
2615 can now connect to each other but nothing really works the way
2616 they are supposed - yet.
2618 * Added new initiator token to RouterConnection configuration
2619 file in silcd/serverconfig.[ch]. It is used to tell whether we
2620 are the initiator to the remote router or whether we'll expect
2621 the other end to connect.
2623 * Moved registering of listener task to silc_server_init, hence
2624 the server starts listenning as soon as it is run, even if it
2625 does not have connections to other routers. Let's see how well
2628 * Changed default connection retry timeouts for more suitable in
2631 * Removed cipher and such arguments from silc_idlist_add_client
2632 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2633 Added new function silc_idlist_add_data to add the keys and stuff
2636 * Added SilcIDListData structure and added it to SilcClientEntry
2637 and SilcServerEntry as their first field in the structure. This
2638 way we can explicitly cast the ID entries to the SilcIDListData
2639 structure and get common data for the entries. In past, we had
2640 to first check what type of connection it is and then cast it to
2641 correct ID entry type. Now, we can directly cast the opaque
2642 pointer to the SilcIDListData (no matter what ID entry it actually
2643 is) and get the data needed.
2645 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2648 in some circumstances even if threre were timeout tasks, though not
2649 IO tasks, but tasks anyway. Now fixed.
2651 * Defined SilcServerConnection structure to hold connection specific
2652 stuff about directly connected servers and routers. The definition
2653 is currently in silcd/server_internal.h. I thought about having
2654 a bit more important role fro this struct but for now it is used
2655 only when connecting to other server (or router actually).
2657 * Added connecting retry support in server when connecting to
2658 router(s). The retry feature implement exponential backoff
2659 algorithm. Also, added SilcServerParams structure to hold default
2660 parameters for server. For now, it include these retry settings
2661 and are hard coded. After server is moded to be as Silc Server
2662 Library this structure will be more important.
2664 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Changed client librarys channel->clients table to SilcList and
2667 changed code accordingly.
2669 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Changed client's channel table to SilcList and changed code
2672 accordingly. Also changed SilcChannelClientEntry to include back-
2673 pointer to the channel so that client entry can use that structure
2674 as list as well and we have fast cross-reference to the channel.
2675 This change dramatically decreased the complexity of channel
2676 handling with client entry and vice versa (removed one extra
2677 loop when searching for channel entry from many functions).
2679 * Changed server->sim from table to SilcDList and changed code
2682 * NAMES command can now be used from user interface. It will show
2683 the user list on the channel, neatly.
2685 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2686 Code now saves realname of the user if it becomes available.
2688 * Renamed configure.in to configure.in.pre and made ./prepare
2689 script to automatically add correct version string to
2690 configure.in which it creates from configure.in.pre.
2692 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * NAMES command reply now shows users mode with the nickname when
2697 * Moved silc_client_ch[u]mode[_char] functions from
2698 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2699 place sucks, they are utility functions and should be in some
2702 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2704 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2707 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Added TRQ (efficient deque and list library) into lib/trq. This is
2712 a very good list library that is currently used in the SILC. Defined
2713 SilcList API over the library because I didn't like the API very
2714 much. See lib/trq/silclist.h for the API and examples of how to
2715 use the API. Fixed various places in the code to use the new
2716 SilcList API. The SilcList is meant for lists that has a structure
2717 already defined as a list. It is not suitable to add just some
2718 context to the list (in TRQ, the context is the list actually).
2720 So, I defined SilcDList that can be used for the purpose where
2721 predefined list structure does not exit. This can be used as
2722 such list. Now some context just can be added to the SilcDList.
2723 Currently this list is not used in the SILC just yet, though there
2724 are a lot places where this can replace dynamically allocated
2725 tables and I will fix these places, later, to use SilcDList.
2726 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2727 and use TRQ internally).
2729 Also fixed some annoying warning messages that the original TRQ
2730 code generated. Also minor changes to TRQ's Makefile.in.
2732 * Added support for querying by Client ID to both WHOIS and
2733 IDENTIFY commands into server, as required by the protocol.
2735 * Removed method function pointers from SilcBuffer structure. They
2736 weren't used to anything and just increased the context size for
2737 no good reason. This change also made silc_buffer_alloc and
2738 silc_buffer_free functions inline functions.
2740 * Disabled command flooding detection support until it's fixed so
2741 that it accepts commands in but does not execute them more than once
2744 * Added silc_net_localhost(), to return local hostname, into
2745 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2746 that must be initialized before calling silc_client_init.
2748 * Added new function: silc_server_send_notify_on_channels to send
2749 notify messages to all channels client has joined. It is assured
2750 that the message is sent only once per client.
2752 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2753 lib/silcutil/silcutil.[ch] as silc_format function. The new
2754 function is generic and is used by server as well, not only by
2755 the logging routines.
2757 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2758 the provided version string was not acceptable. Added new function:
2759 silc_ske_check_version into lib/silcske/silcske.h. The function
2760 must be implemented by the application (client or server) and it
2761 does not reside in the SKE library. The function checks the version
2762 string remote end sent.
2764 * Added back pointers (to opaque context and to SilcSocketConnection)
2765 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2767 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2768 duplicate packet context structure.
2770 * Changed `notify' client operation to send same arguments as client
2771 receives from server except for ID's. ID's are mapped to correct
2772 ID entry and that is returned. Also, if channel entry is not sent
2773 by server but the notify is for channel the channel entry is sent
2774 to application (otherwise application doesn't know that it is for
2775 channel (library gets it from packet's Destination ID)).
2777 * Added silc_client_remove_from_channels into client library to
2778 remove a client from all channels it has joined to. Used when
2779 received SIGNOFF notify from server. Added also new function
2780 silc_client_replace_from_channels to replace old ID entry with
2781 new ID entry on all channels. Used when received NICK_CHANGE
2784 * Fixed ID Cache list handling in silc_idlist_get_client in
2785 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2786 to get (or query) client by ID.
2788 * Updated TODO list.
2790 * Added connection authentication status message defined by the
2791 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2792 support for these into the code in client and server side.
2794 * Added generic function silc_client_send_command to send any command
2795 with variable argument list. Application should use this function
2796 to send commands if the command functions provided by the library
2797 does not suite for the application's user interface needs.
2799 * Added new `failure' client operation. Application is notified about
2800 received failure packet if client is executing a protocol. In this
2801 case the protocol's execution has failed.
2803 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2804 is required by the protocol.
2806 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2807 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2810 * Added status flag to SilcSKE object to indicate realtime status
2811 of the SKE protocol.
2813 * Application receives now exactly same command reply arguments as
2814 the library receives from server. However, if ID is received the
2815 corresponding ID entry is returned to the application (eg. Client
2816 ID is mapped to correct SilcClientEntry entry and that is returned).
2817 Changed command_reply client operation due to this change.
2819 * Changed all ID's in commands and in command replys as ID Payloads.
2820 Change affected both client and server side codes.
2822 All ID's sent in SILC network (with execption of ID's in SILC
2823 Packet header) are sent in ID Payload to support variable length
2826 * Server now notifies nick changes and notifies all clients on
2827 the channels about the new nickname (about the new Client ID,
2830 * Implemented CMODE command to change channel modes. Supports all
2831 channel modes defined by the protocol specs except ban and invite
2832 lists. (Also, private channel key mode is supported but support for
2833 setting private channel key in client is missing, thus, this mode
2834 has no effect on client side (except that server requires that the
2835 client uses private channel key and normal channel traffic does not
2838 Also, invite mode works per se, but INVITE command does not work
2839 yet correctly, so you can set channel as invite only channel but
2840 inviting clients to the channel does not work (it is yet to be
2841 thought what's the best way to do it).
2843 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2844 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2845 Implemented CUMODE command to change user's mode on the channel.
2846 Supports all modes defined by the protocol specs.
2848 * Added NAMES command reply to return users modes on the channel.
2850 * Removed unnecessary and slow ciphers from lib/silccrypt.
2852 * Set SO_KEEPALIVE option to connection sockets by default.
2854 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2856 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2857 redefined the Notify Payload into protocol specs.
2859 * Added silc_id_payload_parse_id to get ID directly from raw
2862 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2865 accept searching by Client ID as well.
2867 * Added support for LEAVE and SIGNOFF notify types in client library.
2869 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2870 to parse ID Payload from raw data.
2872 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Added flags parameter into silc_ske_assemble_security_properties
2875 function in lib/silcske/silcske.[ch].
2877 * Changed notify client operation to fit better for notify messages
2878 sent by server. The notify payload received from server is now
2879 passed to the application (after parsing it to SilcNotifyPayload).
2880 It is application's responsibility to retrieve the arguments
2881 from the payload and show the message the way it wants. The message
2882 sent by server is implementation specific.
2884 * Changed public keys to comply with the protocol specification.
2885 Old public keys are not supported anymore and are not compatible.
2887 * Removed nickname from Channel Payload as the latest draft removed
2888 it. The client must resolve the nickname from the NAMES command
2889 reply received when it joined the channel.
2891 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2893 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Fixed some errors in protocol specification drafts.
2897 * Created lib/silccore/silcnotify.c to implement Notify Payload
2898 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2899 generic payloads described by protocol specifications. The file
2900 includes implementations for ID Payload and Argument Payload.
2902 * Changed Command Payload implementation to use the new Argument
2903 Payload. Changed command_xxxx_payload to command_payload_xxxx
2904 to comply with SILC coding conventions.
2906 * Added suppport for Argument Payload handling in Notify Payload
2907 implementation as protocol requires it. Added the new support
2908 into server and client lib as well.
2910 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Added support for multiple nicknames on same channel. [n] is
2913 added locally to the nickname if there are more than one same
2914 nicknames on the channel.
2916 * Server now sends all nicknames that matched WHOIS request.
2917 Client also shows the list received from server.
2919 * Added TOPIC command to client side. User can now set and show
2920 current topic on channel.
2922 * Added MOTD command to client and server. Also, server sends the
2923 motd when client connects to the server.
2925 * Changed version strings to comply ISO 8601.
2927 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Fixed protocol error handling in client library. It should now
2930 cope even if the SKE fails for some reason.
2932 * Made new protocol specification drafts for submitting to IETF.
2934 * Implemented TOPIC command to server in silcd/command.c.
2936 * Added two new notify types into lib/silccore/silcnotify.h:
2937 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2938 notify nickname change and topic setting/change on a channel.
2940 * API change of command_reply operation in client library. The
2941 application gets now the status type received from server as well.
2943 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2947 * Cras fixed and optimized the packet handling even further and
2948 it should work now. Minor change to the prototype of function
2949 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2951 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added new function into lib/silcutil/silcschedule.[ch]:
2954 silc_schedule_with_fd to select() a specified fd. The function
2955 returns after timeout expires or data arrives or goes. The
2956 function is used by packet routines to wait that all data is
2957 received from network.
2959 * Fixed data reading from network in lib/silccore/silcpacket.c.
2960 The code now assures that all data is read from the fd and then
2961 continues packet processing. This was a bug fix since the code
2962 used to drop some data in some circumstances.
2964 * Added new function into lib/silcclient/client.[ch]:
2965 silc_client_start_key_exchange to start key exchange after
2966 connection has been established to server. The code internally
2967 now uses this funtion but its main purpose was to provide it
2968 for applications that perform their own connecting. After
2969 application has created a connection it merely calls this
2970 function to start the key exchange between client and server.
2971 The library takes care of everything else after that.
2973 Updated also lib/silcclient/README to explain the usage of
2976 * Do not send to application information that connection has
2977 been established. Application gets notified it by connect
2980 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Applied cras's patch to add silc_schedule_one function. The
2983 function runs scheduler once and returns.
2985 * Fixed the scheduler after cras messed it up. The timeout
2986 handling works now as it's supposed to work.
2988 * Added into lib/silccore/ silcnotify.h to include notify
2989 message types support. Changed silc_server_send_notify*
2990 functions, in server.[ch], to support those new notify types.
2991 Added the support for the notify types into client library,
2992 as well. Added new notify client operation into ops.h in
2995 * Changed silc_server_packet_send_to_channel to send normal
2996 packets instead of just channel message packets. The function
2997 is now used to send the notify packets to channels. It is not
2998 used to send channel message packets anymore, as server never
3001 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3002 va_arg()s as it seems to require it nowadays. I guess, if SILC
3003 is compiled with older va_arg() the new code should work anyway.
3005 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Splitted core library. Core library (lib/silccore) includes
3008 now only SILC protocol specific core (and common) components.
3009 Created new utility library (lib/silcutil) that includes more
3010 generic purpose stuff. The stuff for util library was taken
3011 from the old core library. This was minor and easy split.
3013 * Created SILC Client Library (lib/silcclient) that includes
3014 implementation of the SILC client without user interface. This
3015 was major move from silc/ directory. The code has been changed
3016 so that it is transparent towards the user interface. The
3017 silc/ directory includes now the same user interface as before
3018 and it uses the new client library. Read lib/silcclient/README.
3019 Basicly, the client library performs everything else related
3020 to SILC except user interface handling. Also, configuration
3021 files are considered to be part of user interface and library
3022 does not handle them.
3024 This change also changed a lot of structures, function naming etc.
3025 Most important change was that SilcClientWindow object was
3026 renamed to SilcClientConnection in the client library. Created
3027 also new file lib/silcclient/ops.h. Also added new files
3028 silc/local_command.[ch] and silc/client_ops.[ch].
3030 All these changes were made to make it easier for user interface
3031 designers to create what ever user interface for the SILC client
3034 It is also expected that the server will be moved to lib
3035 directory as well and SILC Server Library will be created;
3036 sometimes in the future.
3038 * Removed Local commands from lib/silccore/silccommand.h as
3039 they are application specific and new client library does not
3040 handle any of those anymore.
3042 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3043 old client implementation in silc/.
3045 * Added support for callback functions in SILC_LOG_* macros.
3046 Application can now set its own callbacks that will be called
3047 instead of using the default functions that will always print
3048 the debug messages to stderr (or stdout). Also, debugging can
3049 now be disabled by setting silc_debug to FALSE and re-enabled by
3050 setting it to TRUE. Note, that logging will still work even
3051 if debugging is disabled.
3053 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3054 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3055 silc_log_reset_debug_callbacks.
3057 * To enable debugging in silc client one must give now -d
3058 option on command line.
3060 * Changed silc_schedule_init to automatically allocate task queues
3061 if they are not allocated before calling it.
3063 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added GMP 3.1 into math library.
3067 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3070 a channel in SILC network. The packet is used by servers and
3071 routers to notify other routers that user has left a channel.
3072 This little feature was missing until now. Added the feature
3073 to protocol specification as well.
3075 Added functions: silc_server_send_remove_channel_user and
3076 silc_server_remove_channel_user into server.[ch].
3078 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3079 lib/silccore/silcpacket.h. However, they are not implemented
3082 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Fixed joining to a channel and sending channel messages
3085 between server and router. The channel message sending should
3086 now work inside a cell.
3088 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Fixed the private message sending between server and router.
3091 The private message sending should now work inside a cell.
3093 * Added silc_server_replace_id into server.[ch] to replace
3094 existing ID in the SILC network.
3096 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3097 and silc_idlist_replace_server_id into idlist.[ch] in server.
3099 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Fixed the server to server connections. Server can again now
3102 connect to router. Router to router connections probably does
3105 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added dynamic protocol registering support. Now protocols can
3108 registered and unregistered on the fly. Patch by cras.
3110 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added lib/contrib directory to hold routines that some platforms
3113 don't have but are needed by SILC.
3115 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3116 into lin/contrib to provide getopt() and getopt_long() for
3117 those who don't have it.
3119 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Added AWAY command to client. When away message is set and
3122 client receives a private message packet the client automatically
3123 replies to the sender with the away message.
3125 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3126 bug seemed to be the cause of recent problems when compiling
3129 * Added version detection support to SKE protocol specification
3130 and added the new changes to the SKE implementation as well.
3131 There were other minor changes in the SKE protocol as well.
3133 Many changes in lib/silcske/silcske.[ch] and in
3134 lib/silcske/payload.[ch].
3136 * Added ^U functionality, clear input line. Patch from cras.
3138 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Mainly small bugfixes on core library. Fixed some debugging
3141 logging and buffer overflow in silclog.c.
3143 * Updated config.sub and config.guess on the distribution tree.
3145 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Added command lagging support in server. Client may execute
3148 commands now only once in two seconds.
3150 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Optimized packet reception. MAC computation and checking is now
3153 also more optimized. A lot previously duplicated code is now
3154 used as generic by both client and server.
3156 * Fixed key pair generation in clientutil.c
3158 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3160 * Added into lib/silccore/silcbufutil.[ch] new function;
3161 silc_buffer_realloc.
3163 * Moved generic packet sending/encryption functions to
3164 lib/silccore/silcpacket.[ch] from client and server. Some
3165 rewriting of the functions.
3167 * Moved all generic packet reception/decryption functions to
3168 lib/silccore/silcpacket.[ch] from client and server. The
3169 packet processing is now much cleaner in both client and server.
3170 These were major changes in both client and server.
3172 * Created many common functions in server to do packet sending.
3173 Previously code were duplicated a lot, this has been removed
3176 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Rewrote major parts of the ID cache system. Don't know
3179 whether it is better now or not but at least the API is more
3182 * Major rewrite on ID cache stuff on client because of the ID
3183 cache API changes. Added idlist.c to client.
3185 * Also major rewrite on ID cache stuff on server as well.
3186 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3187 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3188 in hand, instead they are all put into the ID cache system now.
3189 All server_idlist_* routines uses ID cache now instead of
3190 traversing its own lists (those lists does not exist anymore).
3191 SilcIDList though still exists. Also, SilcXXXEntry's are
3194 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Finally made the SKE implementation compliant to the protocol
3197 specification. All mp integers are now binary encoded as
3198 opposed being HEX encoded.
3200 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3203 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3204 functions: silc_[encode/decode]_pem. Also added function
3205 silc_encode_pem_file to PEM encode with newlines ('\n') for
3208 * SILC public keys are now encoded either PEM or binary. Same
3209 option is for private keys as well. By default private keys
3210 are binary encoded and public keys PEM encoded. Silly HEX
3211 encoding were removed.
3213 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3214 function to create fingerprints.
3216 * Fixed a bug in SHA1; does not change the original data anymore.
3218 * Partly implemented INFO command on client and server side.
3219 Fixed CLEAR command. Changes to SERVER command; show current
3220 server(s) when giving command without arguments. Added
3221 VERSION command to client.
3223 * Added check to server that unregistered connections cannot
3224 execute commands (unless it is specificly allowed).
3226 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Fixed screen refresh.
3230 * Fixed channel joining bug from client. On some circumstances
3231 client tried to join to a channel it had already joined.
3233 * Added public key verification process into client's protocol.c.
3234 The client now verifies the public key from user and saves
3235 it into ~./silc/serverkeys/ directory.
3237 Added into: clientutil.[ch]: silc_client_verify_server_key.
3239 * Changed SKE protocol's silc_ske_initiator_finish function
3240 to accept callback function that verifies the received public
3241 key. Removed old silc_ske_verify_public_key function.
3243 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3246 silc_pkcs_private_key[_data]_set.
3248 * Made the password and public authentication more cleaner in
3249 server's protocol.c.
3251 * Removed historic and obsolete protocol `channel_auth' from
3252 both client and server.
3254 * Removed wrong way of sending command status messages from
3255 server to client in server's command.c. The old way violated
3256 protocol specification.
3258 Changes to silccore/silccommand.[ch]: removed
3259 silc_command_encode_status_payload -> not needed anymore,
3260 changed silc_command_encode_payload_va to accept extra
3261 argument on variable argument list. The argument type must
3262 now be provided to the function. Also, added new function:
3263 silc_command_encode_reply_payload_va which is same as
3264 normal command_encode_payload_va except command status type
3265 is provided as extra argument.
3267 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Added ~./silc directory handling. The directory includes the
3270 public and private keys for the client.
3272 Added silc_client_check_silc_dir, silc_client_create_identifier
3273 and silc_client_load_keys.
3275 * Implemented SILC protocol compliant public key. Added public
3276 and private key saving to and loading from files.
3278 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3279 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3280 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3281 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3282 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3284 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3285 silc_pkcs_load_[public/private]_key.
3287 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Added silc_server_get_route (route.[ch]) to get connection
3290 data for the fastest route for given ID.
3292 * Implemented INVITE command on client and server. The command
3293 were re-defined in the SILC Protocol Specification and the
3294 implementation now complies with the specification.
3296 * Implemented PING command on client and server.
3298 * Implemented NAMES command on client and server. The server side
3299 supports currently only normal server not router server yet.
3300 Some changes to NAMES definition in SILC protocol specification.
3302 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Implemented LEAVE command on client and server.
3306 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3307 again. This change was made to the protocol as well. Server
3308 should not violate the protocol specification anymore.
3310 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3313 was tested. SOCKS4 was not but should work anyway.
