3 * Do not parse packets with different timeout when protocol
4 is active -> may cause problem with rekey. Affected file
7 * When server receives signoff notify it must not create
8 new channel key if the client is on any channels since the
9 sender of the signoff notify will create it.
11 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Added printing of error messages during SKE protocol from the
14 failure packet sent by server during SKE. Affected file
17 * Removed the client's failure_callback handling with timeout
18 and handle it immediately when received.
20 * The SKE library returned wrong type in SUCCESS and FAILURE
21 packets. They must be 32 bit MSB not 16 bit MSB.
23 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Ok, rewrote the logic of the re-key and now it seems to work.
26 I tested it on high traffic with frequent re-keys without
27 problems. Added hmac_receive (and renamed hmac to hmac_send)
28 in SilcClientConnection in lib/silcclient/client.h and
29 in SilcIDListData in silcd/idlist.h. Also, removed the
30 SilcPacketParserContext's cipher and hmac fields as they are
31 not needed anymore and actually caused some problems when
32 the ciphers and hmac's changed underneath the packet parser.
34 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
36 * If re-key protocol is active then process the incoming packets
37 synchronously since we must assure that icoming packets encrypted
38 with the old key is processed before the new keys is set to
39 use. This is true other packets than for REKEY packets.
40 Affected file silcd/server.c. The same was done to client library
41 as well, affected file lib/silcclient/client.c.
43 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
45 * Fixed bug in client and server to accept the force send if
46 the packet is send from silc_[server/client]_packet_process
47 function. Otherwise the packets are never delivered, oops.
49 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Disable force sending of packets when REKEY protocol is active.
52 We must assure that no packet is sent directly when rekey is
53 performed. All packets must be sent through packet queue.
54 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
55 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
56 function is silc_[server/client]_packet_send_real to check
59 * Replaced the SIM paths from example config files to
60 /usr/local/modules. Also, make install creates now
61 /usr/local/silc/logs directory to hold all the SILC server
64 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * Made the configure.in.pre work on Solaris. Patch by salo.
68 * Made all ciphers compatible with non-x86 machines. Defined
69 CBC mode macros into lib/silccrypt/ciphers_def.h.
71 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Fixed the make install.
75 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
77 * When MAC computation fails the silc_packet_decrypt returned 0
78 even though it was supposed to return -1. Fixed this. The
79 affected file is lib/silccore/silcpacket.c.
81 * Do not replace the config files in /etc/silc (in make install)
82 if they already exist. Affected file ./Makefile.am.
84 * Do not send re-key packets immediately but through packet queue.
85 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
87 * Changed silc_net_check_host_by_sock to return FALSE if the
88 IP/DNS could not be resolved. Though, it returns the IP address
89 now even if it could not resolve it (but returns also FALSE).
90 Affected file lib/silcutil/silcnet.[ch].
92 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * Added silc_pkcs_decode_identifier to decode the public key's
95 identifier. Affected file lib/silccrypt/silpkcs.[ch].
96 Added also silc_pkcs_free_identifier. Added also new context
97 SilcPublicKeyIdentifier.
99 * Added -S option to the silc client. It is used to dump the
100 contents of the specified public key file.
102 * Changed the PKCS api to return the public key length when
103 setting the public key.
105 * Fixed a fatal bug in the public and private key file loading.
106 Affected file lib/silccrypt/silcpkcs.c.
108 * Execute the packet parsing for client with zero (0) timeout
109 if the protocol is active. Affected file silcd/server.c.
111 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Made the key generation options to the silcd program. Added
114 -C option, equivalent to client's option.
116 * Added new [ServerKeys] config section to the server. It
117 configures the server's public and private key.
119 * Defined generic Public Key Payload into the protocol
120 specification to send specific type of public keys and
123 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
124 public key or certificate.
126 * Implemented the GETKEY command to the server and to the
127 client library and on user interface.
129 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Made preliminary `make install' work.
133 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Added SilcServerRekey context into silcd/idlist.h.
137 * Added the PFS support as defined in the specification to the
138 SKE protocol. Affected files lib/silcske/*.c.
140 * Added `ske_group' field to the SilcServerRekey context to hold
141 the number of the SKE group that is used with PFS in re-key.
142 Affected file silcd/idlist.h.
144 * Added PFS re-key support to the server. Affected file is
147 * Added silc_protocol_cancel to cancel execution of the next
148 state of the protocol. Affected file is
149 lib/silccore/silcprotocol.[ch].
151 * Added the re-key support with and without PFS to the client
152 library. Re-key is performed once in an hour, by default.
154 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
155 Added silc_client_rekey_callback and silc_client_rekey_final.
156 Affected files are lib/silcclient/protocol.[ch] and
157 lib/silcclient/client.[ch].
159 * Removed the `hmac_key' and `hmac_key_len' fields from the
160 SilcClientConnection structure; not needed. Affected file is
161 lib/silcclient/client.h.
165 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Do not ask whether user wants to use the negotiated private key
168 for private messages, just use it. Affected file is
169 silc/local_command.c.
171 * Added `send_enc_key' and `enc_key_len' fields to the
172 SilcIDListData structure since they are needed in the re-key
173 phase. Affected file is silcd/idlist.[ch].
175 * Implemented the simple re-key protocol into the server.
176 Affected files silcd/server.c and silcd/protocol.[ch]. The
177 re-key will be performed once in an hour, by default.
179 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
180 Added silc_server_rekey, silc_server_rekey_callback and
181 silc_server_rekey_final.
183 * Removed Tunneled flag from the protocol. Updated the code
184 and the specifications.
186 * Adde `pfs' field to the SilcIDListData to indicate whether
187 the PFS is to be performed in the re-key. Affected file is
190 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
192 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
193 int64 of at least the xintXX size. If void * is less that 4
194 bytes uint32 * will be used. Defined bool as boolean.
196 * Changed _ALL_ unsigned long and unsigned int to uint32,
197 unsgined short to uint16 in the source tree.
199 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
200 not handle clients that has entry->data.registered == FALSE.
201 They are not in the network anymore. Affected file is
204 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Implemented the sending of the SERVER_SIGNOFF notify in the
207 server. Affected file is silcd/server.c.
209 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
210 Added also silc_notify_payload_encode_args into the
211 lib/silccore/silcnotify.[ch].
213 * Implemented ther SERVER_SIGNOFF notify handling in the server.
214 Affected file silcd/packet_receive.c.
216 * Implemented the SERVER_SIGNOFF notify handling in the client
217 library. Affected file lib/silcclient/client_notify.c. Also,
218 implemnted the printing of the SERVER_SIGNOFF info to the
219 application. Affected file silc/client_ops.c.
221 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
222 if the deleting was successful. Affected file silcd/idlist.[ch].
224 * Added support for public key authentication in the connection
225 authentication protocol in the client library. Affected file
226 lib/silcclient/protocol.c.
228 * Changed the server's silc_idlist_get_clients_by_* interface
229 to support already allocated array so that new entries may be
230 added to pre-allocated array. Affected file silcd/idlist.[ch].
231 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
234 * All command reply functions in the server now calls the
235 pending command callback even if error occured. This way the
236 error will be delivered to the client as well. Affected files
237 silcd/command.c and silcd/command_reply.c.
239 * Fixed INFO command to return local server's info if no server
240 was provided. Affected file lib/silcclient/command.c.
242 * Removed RESTART command for good. Updated the code and the
245 * Rewrote parts of the task system. It is a bit simpler now.
246 Removed unsued task priorities. The affected files are
247 lib/silcutil/silctask.[ch].
249 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Moved the USERS printing from the library to the application.
252 Affected files lib/silcclient/command.c and silc/client_ops.c.
254 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Added channel key re-key support. The re-key is perfomed
259 only by the router and is done once in an hour. Added `rekey'
260 field to the SilcChannelEntry in the server. Affected files
261 silcd/server.c and silcd/idlist.h.
263 * Added silc_task_unregister_by_context into the file
264 lib/silcutil/silctask.[ch].
266 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Added SILC_UMODE_GONE mode to indicate when the client is not
269 present in the SILC network. Added also support to the local
270 command AWAY that will set this mode. Added support of showing
271 "xxx is gone" in WHOIS command. The USERS command shows the
274 * Fixed setting server and router operator privileges in the
275 server's UMODE command. Affected file silcd/command.c.
277 * Merged the SKE KE1 and KE2 payloads into one payload. The
278 new KE payload is equivalent to the old KE2 payload.
280 Cleaned up the SKE Start Payload parsing. It now uses the
281 simple buffer unformatting to do the parsing. A lot faster
284 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
285 to the SKE that is used to indicate whether both of the SKE
286 parties should perform authentication. By default only the
287 responder performs authentication. By setting this flag also
288 the initiator must do authentication. By default it is unset
289 since in normal SKE case, client to server connection, only
290 the responder should do authentication. When doing SKE between
291 two clients both should perform authentication. Updated the
292 code and the protocol specs.
294 * A little fix to IDENTIFY command in the server. Search the
295 client first by hash not nickname. Affected file is
298 * Fixed the silc_client_close_connection to support closing
299 the client to client connections wihtout deleting too much
300 data. Affected file lib/silcclient/client.c.
302 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
303 are received if protocol used to be active but is not anymore
304 the application would crash due to NULL pointer dereference.
305 Affected files silcd/server.c and lib/silcclient/client.c.
307 * Added `hash' field to the SilcClientConnection to include
308 the hash function negotiated in the SKE protocol.
310 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
311 to set the channel founder authentication data. A client can
312 claim the founder rights later by providing the authentication
313 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
314 This way the channel founder can regain the channel founder
315 privileges even it is left the channel. This works only on
316 local server and the client must be connected to the same
317 server to be able to regain the founder rights. Updated the
318 protocol specs accordingly.
320 Added support to the CMODE command in the client to set the
321 founder auth data. Read the README to see how to set it.
323 Added support to the CUMODE command to claim the founder
324 rights. Read the README to see how to do it.
326 Added support for the founder authentication to the Channel
327 Entry in the server. Affected file silcd/idlist.h.
329 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
330 server's CMODE command. Affected file silcd/command.c.
332 * Added the following new functions into lib/silccore/silcauth.[ch]:
333 silc_auth_get_method and silc_auth_get_data.
335 * The server now saves the remote hosts public key to the
336 SilcIDListData pointer. Affected file silcd/protocol.c.
338 * The normal server now does not remove the channel entry from
339 the cache if the founder authentication data is set. It used
340 to remove it if the founder was the last one on the channel on
341 the server and left the channel. The auth data is saved and
342 if the channel is re-joined later the old entry is used with
343 the old auth data. Affected files silcd/command_reply.c and
346 * Removed the `pkcs' field from the SilcIDListData structure
347 in the server; it is not used. Affected file silcd/idlist.h.
349 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Fixed packet processing on slow links. Partial packets were
352 never re-processed because the incoming data buffer was cleared
353 by the application. Application must not directly clear the
354 sock->inbuf, the packet processing routines handle it. Fixed
355 this in client library and in server.
357 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Fixed the WHOIS and IDENTIFY send reply function to really
360 check whether to send list or just one entry. Affected file
363 * Cleaned up the LEAVE command's channel key distribution. The
364 affected file silcd/command.c.
366 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
367 can enforce the channel mode as well. In that case the ID
368 includes the ID of the server. The code now enforces the
369 mode change if the router have different mode than the server.
371 * The notify client operation with CMODE_CHANGE notify can now
372 return NULL client_entry pointer if the CMODE was not changed
373 by client. Application must check for this.
375 * Added <Server ID> argument to INFO command to support server
376 info fetching by Server ID.
378 * Added silc_server_announce_get_channel_users to get assembled
379 packets of channel users of the specified channel. Affected
380 file silcd/server.[ch].
382 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
383 was freed underneath the ID Cache.
385 * Re-announce clients when the server received CHANNEL_CHANGE
386 notify from the router. Affected file silcd/packet_send.c.
388 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
391 crashed since it did not handle the fact that there is no cipher
392 called "3" and didn't check the error condition. Now fixed.
394 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
395 flag. It can be used to send message requests.
397 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
399 * Implemented the RESTART command in the client.
401 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
402 notice type messages. Added notice printing to the user
405 * The channel keys are not re-generated if the channel's mode
406 is PRIVKEY, ie private key on the channel exists. Affected
407 files silcd/server.c and silcd/command.c.
409 * Fixed a little bug in channel message delivery when channel
410 private keys are set in the server. Affected file is
413 * Changed the setting on channel->on_channel = TRUE from the
414 silc_client_save_channel_key to the JOIN command reply. The
415 key payload is not received if the private channel key is set.
416 Affected file lib/silcclient/command_reply.c and the
417 lib/silcclient/client_channel.c.
419 * When the CMODE_CHANGE notify is sent and the channel private
420 key mode is removed the channel key must be re-generated in
421 other cells as well. Added this support for the router in the
422 silcd/packet_receive.c.
424 * Added new local command NOTICE to send notice message on
425 channel. Affected file silc/local_command.[ch].
427 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
429 * Added new local command ME to the client. It is used to send
430 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
431 some action. Affected file silc/local_command.[ch].
433 * Changed channel_message and private_message client operations
434 to deliver the message flags to the application. Added also
435 the `flags' arguments to the silc_client_send_channel_message
436 and silc_client_send_private_message functions. Affected file
439 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Redefined the Private Message Payload to support private message
442 keys and to support the new private message flags. Updated
443 the protocol specs. Flags makes it possible to have for example
446 * Added new type SilcPrivateMessagePayload and defined an API
447 for it in the lib/silcclient/silcprivate.[ch].
449 * Tested private message private keys successfully. Tested the
450 private message key set, unset and list commands with the new
453 * Redefined the Channel Message Payload to include the channel
454 message flags (equal with private message flags) to support
455 for example CTCP style messages.
457 * Defined some of the message (for channel and private message)
458 flags. Updated the protocol specs and added the flags to the
459 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
461 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Added SilcKeyAgreementStatus type to the key agreement routines
464 to indicate the current status and error if one occured.
465 The status types are defined in the lib/silcclient/silcapi.h.
467 * Added new local command KEY that is used to set and unset private
468 keys for channels, set and unset private keys for private messages
469 with remote clients and to send key agreement requests and
470 negotiate the key agreement protocol with remote client. The
471 key agreement is supported only to negotiate private message keys,
472 it currently cannot be used to negotiate private keys for channels,
473 as it is not convenient for that purpose.
475 * Fixed a minor pending callback setting bug in the function
476 silc_client_get_client_by_id_resolve, now the function works.
477 Affected file lib/silcclient/idlist.c.
479 * Added function silc_net_get_local_port to get local bound
480 port by socket. Added to lib/silcutil/silcnet.[ch].
482 * Added `sockets' and `sockets_count' fields to the SilcClient
483 object. They hold the sockets of the listenning sockets in
484 the client. Listenning sockets may be for example the key
485 agreement server. Affected file lib/silcclient/client.[ch].
486 Added functions the silc_client_add_socket and the
487 silc_client_del_socket. They are exported to the application
490 * Added ~./silc/clientkeys to support other client's public keys.
492 * Renamed verify_server_key client operation to verify_public_key
493 and added one argument to indicate the type of the connection
494 (server, client etc.).
496 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Added silc_server_connection_auth_request to handle the
499 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
500 silcd/packet_receive.[ch].
502 * Added silc_server_send_connection_auth_request into the
503 silcd/packet_send.c to send the connection auth request packet.
505 * Cleaned up the silcd/protocol.c a bit and fixed some memory
508 * Fixed the public key authentication in responder side in the
509 server. The `auth_data' pointer includes the SilcPublicKey
510 not the path to the public key. Affected file silcd/protocol.c.
512 * Implemented the public key authentication in the initiator side
513 in the server. Affected file silcd/protocol.c.
515 * Removed the [RedirectClient] config section from the server
516 configuration. Is not needed and I don't want to implement it.
518 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Cleaned up the CMODE command in the server. It now works
521 correctly and supports all the modes defined in the protocol.
522 Affected file is silcd/command.c.
524 * Added `hmac_name' field to the SilcChannelEntry in the server
525 to hold the default HMAC of the channel. It can be set when
526 creating the channel (with JOIN command). Affected files
529 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
530 type to indicate the change of the current cipher and hmac
531 on the channel. Client can safely ignore the <cipher> argument
532 (if it chooses to do so) since the CHANNEL_KEY packet will
533 force the channel key change anyway. The <hmac> argument is
534 important since the client is responsible of setting the new
535 HMAC and the hmac key into use.
537 * Fixed the CMODE command in the client library as well.
539 * Tested CMODE command in router environment successfully.
541 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Show the version of the remote client (or server) when connecting
544 to the server. It is logged to the log file. Affected file
547 * Fixed the KILLED notify handling in the client library. The
548 client must be removed from all channels when receiving the
551 Also, do not remove the client entry when giving the KILL
552 command but when the KILLED notify is received.
554 * Removed silc_idlist_find_client_by_nickname from the server.
555 Not needed anymore. Affected files silcd/idlist.[ch].
557 * Implemented the CHANNEL_CHANGE notify type handling to the
558 server. Affected file silcd/server.c.
562 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Added silc_server_send_notify_invite to send the INVITE
565 notify between routers.
567 * Implemented the INVITE command correctly to the server.
569 * Implemented the INVITE notify type handling in the server.
571 * Implemented the INVITE command to the client library and on the
574 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Added function silc_server_get_client_resolve to find the
577 client entry by ID from all ID lists and then resolve it
578 (using WHOIS) if it cannot be found. Affected file is
581 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Implemented the BAN command to the client library.
585 * The JOIN command in the server now checks the invite list
588 * Changed the silc_command_reply_payload_encode_va and the
589 silc_command_payload_encode_va to support that if argument is
590 NULL it ignores and checks the next argument. Affected file
591 lib/silccore/silccommand.c.
593 * Added silc_server_send_notify_ban to send the BAN notify
594 type between routers.
596 * Chaned the silc_notify_payload_encode to support that if
597 argument is NULL it ignores and checks the next argument.
598 Affected file lib/silccore/silcnotify.c.
600 * Tested ban lists in router environment successfully.
602 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Implemented BAN command to the server, in silcd/command.[ch].
606 * Removed the BAN and INVITE_LIST modes from the CMODE command
609 * Added function silc_string_match to regex match two strings.
610 Affected files lib/silcutil/silcutil.[ch].
612 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Redefined parts of the SilcChannelEntry in the server to support
615 the new ban and invite lists.
617 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Redefined the INVITE command. The same command can be used to
620 invite individuals to the channel but also to manage the invite
621 list of the channel (to add to and remove from the invite list).
622 Updated the protocol specs.
624 * Added new command SILC_COMMAND_BAN that can be used to manage
625 the ban list of the channel. Updated the protocol specs.
627 * Removed the channel modes: the SILC_CMODE_BAN and the
628 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
629 in the CMODE command. The equivalent features are now available
630 using INVITE and BAN commands. Updated the protocol specs.
632 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
633 in the network about change in the current ban list. The notify
634 type is not used by the client.
636 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
637 support the invite lists.
639 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Added new function silc_string_regexify that converts string
642 including wildcard characters into regex string that can
643 be used by the GNU regex library. Added into the file
644 lib/silcutil/silcutil.[ch].
646 Added silc_string_regex_combine to combine to regex strings
647 into one so that they can be used as one regex string by
648 the GNU regex library. Added into the file
649 lib/silcutil/silcutil.[ch].
651 Added silc_string_regex_match to match two strings. It returns
652 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
654 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Imported GNU regex to the soruce tree into lib/contrib.
657 Fixed some compiler warning from the regex.c.
659 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Fixed MOTD command in the server to work in router environment.
663 * Fixed the MOTD command in the client library to support
664 the server argument in the command.
666 * Added `nickname_len' argument to the silc_idlist_add_client
667 in the server, as the `nickname' argument may be binary data
670 * Added silc_idlist_get_channels to return all channels from
673 * Implemented LIST command to the server. Affected file is
676 * Implemented the LIST command to the client library and on the
679 * Added [<user count>] argument to the LIST command reply.
680 With private channels the user count is not shown.
682 * Updated TODO and README.
684 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * The client entry's data.registered must be TRUE even with
687 global client entry on global client list. The data.registered
688 is used to check whether the client is anymore in the network,
689 for example with WHOWAS command so it must be valid.
691 * Fixed the WHOWAS command in the server. It now actually works
692 in router environment. Added function into silcd/command_reply.c
693 silc_server_command_reply_whowas_save.
695 * Added silc_idlist_purge function to the silcd/idlist.c
696 to periodically purge the ID Cache.
698 * Fixed INFO command in the server. It works now in router
699 environment. Added <server name> argument to the INFO command
700 reply. Updated the protocol specs.
702 * Fixed minor bug in silc_idcache_purge to not purge if the
703 expire value is zero.
705 * Fixed various bugs in WHOIS and IDENTIFY command handling as
706 they were buggy because of the WHOWAS information.
708 * Fixed local command MSG to handle the async resolving of
709 the remote client properly. It used to fail the first MSG.
710 Affected file silc/local_command.c.
712 * Added `data_len' field to SilcIDCache context.
714 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Update TODO. Todo in commands in the server.
718 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
721 used by routers as broadcast packet to inform other routers
722 about the changed user mode.
724 Implemented the notify handling in the server. Affected file is
725 silcd/packet_receive.c. Added the function
726 silc_server_send_notify_umode to the silcd/packet_send.[ch].
728 * Added new generic Channel Payload and deprecated the New Channel
729 Payload. The New Channel Payload is now the generic Channel
732 * Added new argument `mode' to the silc_server_send_new_channel
733 as it is required in the Channel Payload now.
735 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
736 and created a new and real SilChannelPayload to represent the
737 new generic Channel Payload. Implemented the encode/decode
738 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
740 * Added silc_server_get_client_channel_list to return the list
741 of channels the client has joined for WHOIS command reply.
742 Affected file silcd/server.[ch].
744 * Implemented the channel list sending in the WHOIS command reply
745 in server and in the client.
747 Implemented the channel list displaying on the user interface
748 as well. Affected file silc/client_ops.c.
750 * Added silc_channel_payload_parse_list to parse list of Channel
751 Payloads. It returns SilcDList list of SilcChannelPayloads.
752 Client for example can use this function to parse the list of
753 channels it receives in the WHOIS command reply. The caller
754 must free the list by calling silc_channel_payload_list_free.
755 Affected files lib/silccore/silcchannel.[ch].
757 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Added one new argument <user mode> to the WHOIS command reply
760 to return the mode of the user in SILC. Updated the protocol
763 Implemented it to the server and client.
765 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Fixed the mode printing on the user interface on joining.
768 Affected file silc/client_ops.c.
770 * Implemented the UMODE command and user modes in general to the
771 client library and to the user interface.
773 * Implemented the UMODE command to the server.
775 * The server now sends UNKNOWN_COMMAND error status if client sends
776 unknown command. Affected file silcd/command.c.
778 * All server commands now handle the command identifier the right
779 way when sending the command reply to the client. The client can
780 use to identify the command replies with the identifier.
782 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added silc_server_get_client_route to resolve the route to
785 the client indicated by the client ID. Affected file is
788 * Added silc_server_relay_packet as general function to relay
789 packet to arbitrary destination. This deprecates functions
790 like _send_private_message_key, _relay_notify etc. Affected
791 file is silcd/packet_send.[ch].
793 Removed silc_server_send_key_agreement,
794 silc_server_send_private_message_key and
795 silc_server_packet_relay_notify functions from the file
796 silcd/packet_send.[ch].
800 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
801 server. Affected file silcd/packet_receive.[ch].
803 * Implemented the KILL command to the client. Implemented the
804 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
805 Affected files lib/silcclient/command[_reply].c and
806 lib/silcclient/client_notify.c. Implemented the KILL notify
807 printing in the user inteface.
809 * Fixed a lot silc_parse_nick memory leaks from the client
810 library in the file lib/silcclient/command.c.
812 * Changed the silc_server_send_notify_on_channels's `sender'
813 argument from SilcSocketConnection to SilcClientEntry to
814 check the sender as entry and not as connection object and not
815 to send to the client provided as argument. The affected file
816 is silcd/packet_send.[ch].
818 * The notify packets that are destined directly to the client used
819 to not to be processed by the server. Now changed that and the
820 server processes all notify packets. After relaying the packet
821 to the client the notify packet is processed in the server.
823 * The silc_server_free_client_data now checks whether there is
824 pending outgoing traffic for the client and purges the data to
825 the network before removing the client entry.
827 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
830 an client is killed from the SILC Network. Updated the protocol
833 Added new function silc_server_send_notify_killed to the
834 silcd/packet_send.[ch].
836 * Added function silc_server_packet_relay_notify to relay notify
837 packets that are destined directly to a client. In this case
838 the server does not process the notify packets but merely relays
839 it to the client. Affected file silcd/packet_send.[ch].
841 Added also silc_server_packet_process_relay_notify to check
842 whereto relay the notify. Affected file is
843 silcd/packet_receive.[ch].
845 * Implemented the KILL command to the server.
849 * Added the backup schema desgined last fall to the protocol
850 specs for everyone to see. The specification is in the
851 *-spec-xx.txt draft and the packet type definitions for the
852 backup routers is in *-pp-xx.txt draft. Thusly, added also
853 new packet type SILC_PACKET_CELL_ROUTERS.
855 * A big security problem in the implementation discovered. The
856 signoff of an client did not cause new channel key generation
857 which it of course should've done. The channel keys must be
858 always re-generated when client leaves (or signoffs) the channel.
859 The silc_server_remove_from_channels funtion now handles
860 the channel key re-generation.
862 * Added `sender' argument to the silc_server_send_notify_on_channels
863 to not to send the client provided as argument. Affected file
864 silcd/packet_send.[ch].
866 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Implemented OPER and SILCOPER commands into the server and
871 * Added silc_auth_verify and silc_auth_verify_data to verify
872 the authentication directly from the authentication payload.
873 It supports verifying both passphrase and public key based
874 authentication. Affected file lib/silccore/silcauth.[ch].
876 * Added `hash' field to the SilcIDListData structure. It is the
877 hash negotiated in the SKE protocol. Affected file is
880 * Slight redesigning of the SilcAuthPayload handling routines.
881 Do not send SilcPKCS but SilcPublicKey as argument.
883 * Implemented the public key authentication support to the
884 serverconfig. The public key is loaded from the provided path
885 and saved as authentication data to void * pointer. Thus,
886 changed the unsigned char *auth_data to void *auth_data;
888 * Fixed SHUTDOWN command to send the reply before the server
889 is shutdown. :) Affected file silcd/command.c.
891 * Fixed fatal bug in CONNECT command. The hostname was invalid
892 memory and server crashed. Affected file silcd/command.c.
894 * Fixed fatal bug in CLOSE command. The server_entry became
895 invalid but was referenced later in the command. Affected file
898 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Fixed fatal bug in failure packet handling. Server ignored
901 the failure and thus crashed when it came.
905 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
908 that the command may be executed only once in (about) 2 seconds.
909 The old SILC_CF_LAG flag is same but allows command bursts up
910 to five before limiting.
912 Added the support for CF_LAG and CF_LAG_STRICT flags to the
913 server code. Various commands now includes the CF_LAG_STRICT
914 flag to disallow any kind of miss-use of the command.
916 * Fixed the silc_buffer_unformat to not to allocate any data
917 if the length of the data is zero. It used to allocate the
918 length + 1. Affected file lib/silcutil/silcbuffmt.c.
920 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Changed the format of AdminConnection configuration section
923 in the server. Added username of the admin to the format.
924 Affected files silcd/serverconfig.[ch].
926 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
927 to return admin configuration data by host, username and/or
930 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Implemented WHOWAS command to the server. Added the functions:
934 silc_server_command_whowas_parse,
935 silc_server_command_whowas_send_reply,
936 silc_server_command_whowas_from_client and
937 silc_server_command_whowas_from_server
939 * Added <Client ID> argument to the WHOWAS command reply. Updated
940 the protocol specs accordingly.
942 * Implemented WHOWAS command and command_reply to the client
945 Implemented the WHOWAS printing on the user interface.
947 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Added new argument to the WHOWAS command reply, the real name.
950 It is an optional argument. Updated the protocol specs.
952 * Added SilcIDCacheDestructor callback that is registered when
953 the SilcIDCache is allocated. The callback is called when
954 an cache entry in the ID Cache expires, or is purged from the
955 cache. Added into lib/silccore/idcache.[ch].
957 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
958 to destruct the client entries when the cache entry expires.
959 Other ID Cache's in server and in the client library ignores
962 * If the ID Cache entry's `expire' field is zero then the entry
963 never expires. Added boolean `expire' argument to the
964 silc_idcache_add function in the lib/silccore/idcache.[ch].
965 If it is TRUE the default expiry value is used.
967 * Added silc_server_free_client_data_timeout that is registered
968 when client disconnects. By default for 5 minutes we preserve
969 the client entry for history - for WHOWAS command.
971 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Added support to the server to enforce that commands are not
974 executed more than once in 2 seconds. If server receives
975 commands from client more frequently, timeout is registered
976 to process the commands. Affected file silcd/command.c.
977 Added new function silc_server_command_process_timeout.
979 * Changed NICK_NOTIFY handling in client library to check that
980 if the client's nickname was changed, so there is no need to
981 resolve anything from the server.
983 * Removed error printing from the WHOIS and IDENTIFY commands.
984 If error occurs then it is ignored silently in the client library.
985 The application, however, may map the received error to
986 human readable error string. The application currently maps
987 the NO_SUCH_NICKNAME error to string.
989 * Made the command status message public to the application. Moved
990 them from lib/silcclient/command_reply.c to
991 lib/silcclient/command_reply.h. The application can map the
992 received command status to the string with the
993 silc_client_command_status_message function.
995 * Added check to the server to check that client's ID is same
996 as the Source ID in the packet the client sent. They must
999 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Added dist-bzip hook to the Makefile.am to make bzip2
1002 compressed distributions.
1004 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Server now enforces the maximum length for the nickname and
1007 the channel as protocol specification dictates. 128 bytes for
1008 nickname and 256 bytes for channel name.
1010 * Moved the WHOIS printing to the application. The client libary
1011 does not print out the WHOIS information anymore, the application
1012 must do it. Renamed silc_client_command_reply_whois_print to
1013 the silc_client_command_reply_whois_save.
1015 The client's idle time is also sent to the application now, and
1016 the idle is shown on screen.
1018 * Added silc_client_command_reply_identify_save to save the
1019 received IDENTIFY entries.
1021 * Do not check for channel private keys in message sending and
1022 reception if the channel does not have the PRIVKEY mode set.
1023 Affected file lib/silclient/client_channel.c.
1025 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1028 just surfaced after chaning the JOIN procedure.
1030 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Added silc_client_get_clients_by_list to get client entries
1033 from Client ID list, that is returned for example by JOIN
1034 and USERS command replies. The application should use this
1035 function for example when JOIN command reply is received to
1036 resolve the clients already on the channel (library does not
1037 do that anymore as USERS command reply is not used in the JOIN
1038 procedure anymore). Affected files lib/silcclient/silcapi.h and
1039 lib/silcclient/idlist.c.
1041 * JOIN command reply and USERS command reply returns now SilcBuffer
1042 pointers instead of unsigned char pointers when returning
1043 the client list and mode list.
1045 * Added <Client ID> argument to the JOIN command reply, mainly
1046 for the server to identify for which client the command was
1047 originally sent. Updated protocol specs accordingly.
1049 * Added SilcDlist private_key pointer to the SilcChannelEntry
1050 in the client to support the channel private keys. Affected
1051 file is lib/silcclient/idlist.h.
1053 * Added SilcChannelPrivateKey argument to the function
1054 silc_client_send_channel_message so that application can choose
1055 to use specific private ke if it wants to. If it is not provided,
1056 the normal channel key is used, unless private keys are set.
1057 In this case the first (key that was added first) is used
1058 as the encryption key.
1060 * Implemented the support for channel private key handling.
1061 Implemented the following functions:
1063 silc_client_add_channel_private_key,
1064 silc_client_del_channel_private_keys,
1065 silc_client_del_channel_private_key,
1066 silc_client_list_channel_private_keys and
1067 silc_client_free_channel_private_keys
1069 Affected file lib/silcclient/client_channel.c.
1071 * Added the support for the private keys in the channel message
1072 sending and encryption and in the message reception and
1073 decryption. Affected funtions are
1074 silc_client_send_channel_message and silc_client_channel_message.
1076 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Added SKE's key verify callback to the client library's
1079 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1081 * Removed the statement that server (or router) must send USERS
1082 command reply when joining to the channel so that the client
1083 knows who are on the channel. Instead, the client list and
1084 client's mode list is now sent in the JOIN command reply to the
1085 client who joined channel. This is better solution.
1087 * Added function silc_server_get_users_on_channel and function
1088 silc_server_save_users_on_channel to the silcd/server.[ch].
1090 * Removed function silc_server_command_send_users from the
1093 * Do not show topic on the client library anymore. The topic is
1094 sent in the command reply notify to the application and the
1095 application must show the topic now.
1097 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Added client searching by nickname hash into the IDENTIFY and
1100 WHOIS commands in the server as they were clearly missing from
1101 them. Affected file is silcd/command.c.
1103 * Fixed a bug in private message receiving in the client library.
1104 The remote ID was freed and it wasn't supposed, now it is
1107 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Minor fix to the channel payload; allocate the data area, as it
1110 needs to be of specific length.
1112 * If the key agreement port is zero then the operating
1113 system will define the bound port. Affected files are
1114 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1116 * Added new function silc_channel_payload_decrypt into the file
1117 lib/silccore/silcchannel.[ch].
1119 * Moved the channel message etc, check from silc_packet_decrypt
1120 to applications. The library calls now a generic
1121 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1122 when the packet is either normal or special. This was done to
1123 allow more wide range of checking that was not allowed when
1124 the code was in library. Now applications can do virtually any
1125 checks to the packet and return to the library the decision how
1126 the packet should be processed. Affected files are
1127 lib/silccore/silcpacket.[ch].
1129 Added silc_server_packet_decrypt_check to the server and
1130 silc_client_packet_decrypt_check to the client library.
1132 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1133 to send with specified source and destination information.
1135 * Channel message delivery between routers was broken after the
1136 channel key distribution was fixed earlier. The channel key
1137 was used be to distributed to other routers as well which is not
1138 allowed by the protocol. Now this is fixed and channel keys
1139 really are cell specific and the channel message delivery between
1140 routers comply with the protocol specification.
1142 * Fixed various commands in server to check also the global list
1143 for the channel entry and not just the local list. The affected
1144 file silcd/command.c.
1146 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Added assert()s to buffer formatting and unformatting routines
1149 to assert (if --enable-debug) when error occurs. Affected
1150 file: lib/silcutil/silcbuffmt.c.
1152 * Changed to auto-reconnect to check whether the remote host is
1153 router and register the re-connect timeout if it is. It used
1154 to check that whether we are normal server, but router must do
1155 auto-reconnect with another router as well. Affected file
1158 * Removed the [<key len>] option from CMODE command as the cipher
1159 name decides the key length, nowadays. See the defined ciphers
1160 from the protocol specification.
1162 * Added [<hmac>] option to the CMODE command to define the HMAC
1163 for the channel. Added SILC_CMODE_HMAC channel mode.
1165 * Added [<hmac>] option for the JOIN command so that user can
1166 select which HMAC is used to compute the MACs of the channel
1169 * Added Hmac field to the Channel Message Payload. The integrity
1170 of plaintext channel messages are now protected by computing
1171 MAC of the message and attaching the MAC to the payload. The
1172 MAC is encrypted. Now, it is clear that this causes some
1173 overhead to the size of the packet but rationale for this is that
1174 now the receiver can verify whether the channel message decrypted
1175 correctly and also when private keys are set for the channel the
1176 receiver can decrypt the packet with several keys and check from
1177 the MAC which key decrypted the message correctly.
1179 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1180 lib/silccrypt/silccipher.[ch].
1182 * Added silc_hash_len to return the digest length into the
1183 lib/silcrypt/silchash.[ch].
1185 * Rewrote parts of Silc Channel Payload interface in the
1186 lib/silccore/silcchannel.[ch]. The encode function now also
1187 encrypts the packet and parse function decrypts it.
1189 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Fixed a minor formatting bug in the SKE's key material processing.
1192 It actually might have processed the keys wrong way resulting
1195 * Redefined the mandatory HMAC algorithms and added new algorithms.
1196 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1197 and hmac-md5 truncated to 96 bits. The mandatory is now
1198 hmac-sha1-96. Rest are optional (including the one that used
1199 to be mandatory). Rationale for this is that the truncated HMAC
1200 length is sufficient from security point of view and can actually
1201 make the attack against the HMAC harder. Also, the truncated
1202 HMAC causes less overhead to the packets. See the RFC2104 for
1205 * Added new [hmac] configuration section. The SKE used to use
1206 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1207 is of course wrong. The official names that must be proposed in
1208 the SKE are the ones defined in the protocol specification
1209 (hmac-sha1-96 for example). The user can configure any hmac
1210 using any hash function configured in the [hash] section. At
1211 least, the mandatory must be configured.
1213 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1215 * Added HMAC list to the SKE proposal list. It has now both
1216 hash algorithm list and HMAC list. This makes the protocol
1217 incompatible with previous versions. The SKE now seems to work
1218 the way it is supposed to work, for the first time actually.
1220 * Defined plain Hash algorithms to the protocol specification.
1223 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Implemented support for key agreement packets into the server.
1226 Added functions silc_server_key_agreement and
1227 silc_server_send_key_agreement. Other than these functions,
1228 server has nothing to do with this packet.
1230 * Added support for private message key packets into the server.
1231 Added functions silc_server_private_message_key and
1232 silc_server_send_private_message_key.
1236 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1237 called in the protocol's final callback instead in the END
1238 protocol state. This makes a little more sense and in the same
1239 time in client we can use the same protocol routines for normal
1240 key exchange and to key agreement packet handling as well.
1242 * Added to both client's and server's KE protocol context the
1243 SilcSKEKeyMaterial pointer to save the key material. We will
1244 bring the key material to the protocol's final callback by doing
1245 this. The final callback must free the key material.
1247 * Added SKE's packet_send callback into client's KE protocol
1248 context so that the caller can choose what packet sending function
1249 is used. This way we can use different packet sending when
1250 doing normal SKE when doing key agreement packet handling (in
1251 the key agreement packet handling we do not want to encrypt
1254 * Implemented the responder side of the key agreement routines
1255 in the client. The client can now bind to specified port and
1256 accept incoming key negotiation. The key material is passed
1257 to the application after the protocol is over.
1259 * Implemented the processing of incoming Key Agreement packet
1260 in the client. Added function silc_client_key_agreement to
1263 * Implemented the intiator side of the key agreement routines
1264 in the client. The client can now initiate key agreement with
1265 another remote client. The key material is passed to the
1266 application after the protocol is over.
1268 * Created client_keyagr.c to include all the key agreement
1271 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1272 SILC_TASK_CALLBACK except that it is not static.
1274 * Created client_notify.c and moved the Notify packet handling
1275 from the client.[ch] into that file.
1277 * Created client_prvmsg.c and moved all private message and
1278 private message key routines from the client.[ch] into that file.
1280 * Create client_channel.c and moved all channel message and
1281 channel private key routines from the client.[ch] into that file.
1283 * Changed silc_client_get_client_by_id_resolve to resolve with
1284 WHOIS command instead of IDENTIFY command, in the file
1285 lib/silclient/idlist.c.
1287 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Implemented the SKE's responder side to the Client library.
1291 * When FAILURE is received to the protocol do not trust it
1292 blindly. Register a timeout to wait whether the remote closes
1293 the connection as it should do it, only after that process the
1294 actual failure. This was changed to both client and server.
1296 * Added client_internal.h to include some of the structures
1297 there instead of client.h in lib/silcclient/.
1299 * Added function silc_task_unregister_by_callback to unregister
1300 timeouts by the callback function.
1302 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Some "Incomplete WHOIS info" errors has been appearing on the
1305 log files. Took away the entry->userinfo check from WHOIS
1306 reply sending. The entry->userinfo is now " " if client did not
1307 provide one. I thought this was fixed earlier but something
1308 is wrong still. Let's see if the error still appears.
1310 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Fixed a minor bug in the login when the channel key is
1313 re-generated in the server. It used to generate the key in
1314 wrong order and thus caused problems in the channel traffic.
1316 * Fixed a minor bug in channel key distsribution after
1317 KICK command. The key was not sent to the router even though
1320 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Added silc_ske_process_key_material_data as generic routine
1323 to process any key material as the SILC protocol dictates. The
1324 function is used by the actual SKE library but can be used by
1325 applications as well. This relates to the private message keys
1326 and the channel private keys since they must be processed the
1327 same way the normal SILC session keys. The protocol dictates
1328 this. Affected files: lib/silcske/silcske.[ch].
1330 Added also silc_ske_free_key_material to free the
1331 SilcSKEKeyMaterial structure.
1333 * Defined silc_cipher_set_key function to set the key for
1334 cipher without using the object's method function. The affected
1335 files: lib/silccrypt/silccipher.[ch].
1337 * Implemented silc silc_client_add_private_message_key,
1338 silc_client_add_private_message_key_ske,
1339 silc_client_del_private_message_key,
1340 silc_client_list_private_message_keys and
1341 silc_client_free_private_message_keys functions in the
1344 Added functions silc_client_send_private_message_key to send
1345 the Private Message Key payload and silc_client_private_message_key
1346 to handle incoming Private Message Key payload.
1348 * Added Cipher field to the Private Message Key payload to set
1349 the cipher to be used. If ignored, the default cipher defined
1350 in the SILC protocol (aes-256-cbc) is used.
1352 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1354 * Removed lib/silcclient/ops.h file.
1356 Redefined parts of the SILC Client Library API. Created new
1357 file silcapi.h that deprecates the ops.h file and defines the
1358 published Client Library API. Defined also private message key
1359 API and channel private key API into the file.
1361 This is the file that the application must include from the
1362 SILC Client Library. Other files need not be included by
1363 the application anymore.
1365 * Added new key_agreement client operation callback and also
1366 defined the Key Agreement library API for the application.
1368 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1371 is used by clients to request key negotiation between another
1372 client in the SILC network. If the negotiation is started it
1373 is performed using the SKE protocol. The result of the
1374 negotiation, the secret key material, can be used for example
1375 as private message key.
1377 Implemented the Key Agreement payload into the files
1378 lib/silccore/silauth.[ch].
1380 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Redefined ciphers for the SILC protocol. Added some new ciphers
1383 and defined the key lengths for the algorithms. Changed the
1384 code accordingly. The default key length is now 256 bits.
1386 * Fixed SKE key distribution function silc_ske_process_key_material
1387 when the key length is more than 128 bits. The default key
1388 length in SILC is now 256 bits.
1390 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1391 to indicate unsupported algorithm.
1393 * Renamed rijndael.c to aes.c and all functions as well.
1395 * Fixed a long standing channel key setting bug in client library.
1396 Weird that it has never surfaced before.
1398 * Fixed bug in channel deletion. If the entire channel is removed
1399 then it must also delete the references of the channel entry
1400 from the client's channel list as the client's channel entry and
1401 the channel's client entry share same memory.
1403 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Implemented CONNECT and SHUTDOWN commands in the client.
1407 * Implemented CLOSE command to the client.
1409 * Added the function silc_idlist_find_server_by_name into the
1410 files silcd/idlist.[ch].
1412 Added the function silc_idlist_find_server_by_conn into the
1413 files silcd/idlist.[ch].
1415 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * DIE command was renamed to SHUTDOWN. Updated the both code
1420 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1421 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1423 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1426 * Added function silc_server_create_connection function to create
1427 connection to remote router. My server implementation actually
1428 does not allow router to connect to normal server (it expects
1429 that normal server always initiates the connection to the router)
1430 so the CONNECT command is only good for connecting to another
1433 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1436 or some other client was kicked from the channel.
1438 Implemented the handling of the notify type to both client
1441 Implemented silc_server_send_notify_kicked to send the KICKED
1442 notify. It is used to send it to the server's primary router.
1444 * Implemented the KICK command into server and client.
1446 * Added `query' argument to the silc_idlist_get_client function
1447 to indicate whether to query the client from server or not if
1450 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1451 to indicate that the client is not channel founder.
1455 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1457 * Removed the rng context from SilcPacketContext structure and
1458 changed that the packet routine uses the Global RNG API.
1460 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1462 * Added support for quit message that client can "leave" on the
1463 channel when it quits the SILC. It is ditributed inside the
1464 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1466 Added silc_server_free_client_data that will take the
1467 signoff message as argument.
1469 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1471 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Updated parts of the protocol specification to keep it up
1476 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1479 payloads in one packet.
1481 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1482 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1483 use now the new List flag.
1485 * Also deprecated the following packet types: REPLACE_ID,
1486 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1488 * Added list support for Notify packet in server.
1490 * Added silc_server_send_notify_channel_change to send the
1491 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1492 the silc_server_send_replace_id.
1494 * Added silc_server_send_notify_nick_change to send the
1495 NICK_CHANGE notify type. Deprecates the function
1496 silc_server_send_replace_id.
1498 * Added silc_server_send_notify_join to send the JOIN notify type.
1499 Deprecates the function silc_server_send_new_channel_user.
1501 * Added silc_server_send_notify_leave to send LEAVE notify type.
1502 Deprecates the function silc_server_send_remove_channel_user.
1504 * Added silc_server_send_notify_cmode and
1505 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1506 types. Deprecates the silc_server_send_set_mode function.
1508 * Added SERVER_SIGNOFF notify type to indicate that server has
1509 quit. This means that all clients on the channel from that
1510 server will drop. This can be also used when netsplit happens.
1512 Deprecated REMOVE_ID packet type since it is not needed anymore
1515 Added silc_server_send_notify_server_signoff to send the
1516 SERVER_SIGNOFF notify type. Deprecates the function
1517 silc_server_send_remove_id.
1519 Added also silc_server_send_notify_signoff to send the
1520 SIGNOFF notify type.
1522 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1523 SILC protocol from this day on. Changed the protocol
1524 specification as well.
1526 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1527 notify type. It is used between routers to notify about
1528 topic changes on a channel.
1530 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1533 * Partly updated the protocol specification to comply with the
1534 changes now made. It is still though a bit outdated.
1536 * The JOIN notify type now takes one extra argument <Channel ID>.
1537 The packet used to be destined to the channel but now the
1538 JOIN type may be sent as list thus it is impossible to
1539 destine it to any specific channel. By adding this argument
1540 it is again possible.
1542 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Added CREDITS file. The CHANGES and CREDITS file will appear
1545 in the distribution as well.
1547 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1549 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1550 types in the server's silcd/packet_receive.c.
1552 * Implemented CMODE and CUMODE to work in router environment.
1554 * Fixed minor encoding and decoding buglet from the
1555 lib/silccore/silcmode.c.
1557 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1560 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1562 * Changed all SilcConfigServer* and silc_config_server* to
1563 SilcServerConfig* and silc_server_config*, respectively.
1566 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Associated the ID (client or server ID) to the Authentication
1569 Payload to avoid any possibility of forging. Updated the
1570 protocol specification and the code accordingly.
1572 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * The RSA key length is now save to the RsaKey context in the
1575 key generation process in lib/silccrypt/rsa.c. The key length
1576 is now used to figure out the maximum size of the block allowed
1577 to be encrypted/signed.
1579 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1580 is equivalent to the silc_mp_mp2bin but does not allocate any
1583 * Changed silc_mp_mp2bin API to take length argument. If it is
1584 non-zero then the buffer is allocated that large. If zero, then
1585 the size is approximated using silc_mp_sizeinbase, which however
1588 * Created Global RNG API which is global RNG that application can
1589 initialize. After initializing, any routine anywhere in the
1590 code (including library) can use RNG without allocating a new
1591 RNG object. This was done to allow this sort of use of the
1592 RNG in code that has no chance to allocate RNG object. All
1593 applications currently allocate this and many routines in the
1594 library use this. Affected file lib/silccrypt/silcrng.[ch].
1596 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1597 it to use the Global RNG API.
1599 * Defined Authentication Payload into protocol specification that
1600 is used during SILC session to authenticate entities. It is
1601 used for example by client to authenticate itself to the server
1602 to obtain server operator privileges.
1604 Implemented this payload into the lib/silccore/silcauth.[ch].
1605 Implemented also routines for public key based authentication
1606 as the new protocol specification dictates.
1608 Moved definitions of different authentication methods from
1609 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1611 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1612 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1613 silc_pkcs_verify_with_hash functions into the file
1614 lib/silccrypt/silcpkcs.[ch].
1616 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * The client entry's userinfo pointer must be always valid.
1619 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1620 will fail since it requires the userinfo. Now, the userinfo
1621 is allocated as "" if actual userinfo does not exist. Actually,
1622 it must exist and it is totally Ok to drop client connections
1623 that does not announce the userinfo. However, we will make
1624 this workaround for now.
1626 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1627 to return the remote port by socket.
1629 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1632 SILC_SERVER_PENDING_EXEC and added an new macro
1633 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1634 data or when error occurs while processing the pending command.
1636 Added new argument `destructor' into silc_server_command_pending
1637 and to the SilcServerCommandPending object. This destructor is
1638 now called after calling the pending callback or if error occurs
1639 immediately. If error occurs the actual pending callback won't
1640 be called at all - only the destructor. The destructor may be
1641 NULL if destructor is not needed.
1643 All this applies for client library code as well. Similar
1644 changes were made there as well for the pending commands.
1646 In the client, the application must now allocate the
1647 SilcClientCommandContext with the silc_client_command_alloc
1650 * Added reference counter to the SilcServerCommandContext. Added
1651 function silc_server_command_alloc and silc_server_command_dup
1654 Same type of functions added to the client library for the same
1657 * Removed the cmd_ident from IDListData away since it is now
1658 global for all connections. It is the command identifier used
1659 in command sending and with pending commands. The affected file
1662 * Added reference counter to the SilcSocketConnection objecet to
1663 indicate the usage count of the object. The object won't be
1664 freed untill the reference counter hits zero. Currently only
1665 server uses this, and client ignores it. The client must be
1666 set to use this too later. The affected files are
1667 lib/silccore/silcsockconn.[ch]. Added also the function
1668 silc_socket_dup to increase the reference counter.
1670 This was mainly added because it is possible that the socket
1671 is removed underneath of pending command or other async
1672 operation. Now it won't be free'd and proper DISCONNECTING
1673 flags, etc. can be set to avoid sending data to connection that
1674 is not valid anymore.
1676 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1677 the connection. After that it sets SILC_SET_DISCONNECTED.
1678 It is, however, possible that the socket data is not still freed.
1679 The silc_server_packet_process now checks that data is not
1680 read or written to connection that is DISCONNECTED. The socket
1681 get's freed when the reference counter hits zero.
1683 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * Changed the client operation API: channel_message operation's
1686 `sender' is now the client entry of the sender, not the nickname
1687 and the `channel' is the channel entry, not the channel name.
1689 In the private_message operation the `sender' is now also the
1690 client entry of the sender not the nickname.
1692 Affected file is lib/silcclient/ops.h and all applications
1693 using the client operations.
1695 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Moved the calling of ops->connect() from connect_to_server_final
1698 into receive_new_id functin since that is the point when the
1699 client is actually allowed to send traffic to network. The
1700 affected file is lib/silcclient/client.c.
1702 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1705 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1706 (if needs broadcasting) instead of broadcasting the packets one
1707 by one which would make a burst in the network traffic.
1709 * Added `broadcast' argument to the functions in silcd/server.[ch]
1710 silc_server_create_new_channel[_with_id] to indicate whether
1711 to send New Channel packet to primary router.
1713 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Added new function into the silcd/server.[ch] files:
1716 silc_server_create_new_channel_with_id to create new channel with
1717 already existing Channel ID.
1719 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1720 lib/silccore/silcpacket.h. This packet is used t send list of
1721 Set Mode payloads inside one packet. Server uses this to set
1722 the modes for the channels and clients on those channels, that it
1723 announced to the router when it connected to it. The protocol
1724 specification has been updated accordingly.
1726 * The silc_server_new_channel did not handle the packet coming
1727 from normal server as it normally does not send that. However,
1728 when it announces its channels it does send it. Implemented
1729 the support for that.
1731 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1732 into the file lib/silccore/id.h.
1734 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Fixed memory leaks in the functions silc_idlist_del_client,
1737 silc_idlist_del_channel and silc_idlist_del_server in the file
1738 silcd/idlist.c. All of those leaked like a sieve.
1740 * Fixed some small memory leaks in the client's function
1741 silc_client_notify_by_server.
1743 * Added functions into silcd/server.c: silc_server_announce_clients,
1744 silc_server_announce_channels and silc_server_announce_server.
1745 These functions are used by normal and router server to announce
1746 to its primary router about clients, channels and servers (when
1747 router) that we own. This is done after we've connected to the
1750 These functions effectively implements the following packet types:
1751 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1752 and SILC_PACKET_NEW_ID_LIST.
1754 * Added new functions into the silcd/packet_receive.[ch]:
1755 silc_server_new_id_list, silc_server_new_channel_list and
1756 silc_server_new_channel_user_list to handle the incoming
1757 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1759 * Added support of changing Channel ID in the function
1760 silc_server_replace_id. If the server that announces a channel
1761 to the router already exists in the router (with same name but
1762 with different Channel ID), router is responsible to send
1763 Replace ID packet to the server and force the server to change
1764 the Channel ID to the one router has.
1766 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1767 client that the Channel ID has been changed by the router. The
1768 normal server sends this to the client. Client must start using
1769 the new Channel ID as the channel's ID.
1771 Implemented handling of this new type into lib/silcclient/client.c
1772 into the function silc_client_notify_by_server.
1774 * Added new function silc_idlist_replace_channel_id into the files
1775 silcd/idlist.[ch] to replace the Channel ID.
1777 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Call silc_server_command_identify_check always when processing
1780 the IDENTIFY command in silcd/command.c
1782 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1785 send keepalive packets. The packet can be sent by clients,
1786 servers and routers.
1788 Added function silc_socket_set_heartbeat into the file
1789 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1790 If not set, the heartbeat is not performed. The actual
1791 heartbeat is implemented in the low level socket connection
1792 library. However, application is responsible of actually
1795 Added silc_server_send_heartbeat to send the actual heartbeat
1796 packet into silcd/packet_send.[ch]. Server now performs
1797 keepalive with all connections.
1799 * Added silc_task_get_first function into lib/silcutil/silctask.c
1800 to return the timeout task with shortest timeout. There was a bug
1801 in task unregistration that caused problems. TODO has been
1802 updated to include that task system must be rewritten.
1804 * The client library will now resolve the client information when
1805 receiving JOIN notify from server for client that we know but
1806 have incomplete information.
1808 * Rewrote parts of silc_server_remove_from_channels and
1809 silc_server_remove_from_one_channel as they did not remove the
1810 channel in some circumstances even though they should've.
1812 * Encryption problem encountered in server:
1814 The LEAVE command used to send the Channel Key packet to the
1815 router immediately after generating it. However, the code
1816 had earlier sent Remove Channel user packet but not immediately,
1817 ie. it was put to queue. The order of packets in the router
1818 was that Channel Key packet was first and Remove Channel User
1819 packet was second, even though they were encrypted in the
1820 reverse order. For this reason, MAC check failed. Now, this
1821 is fixed by not sending the Channel Key packet immediately but
1822 putting it to queue. However, this is more fundamental problem:
1823 packets that are in queue should actually not be encrypted
1824 because packets that are sent immediately gets encrypted
1825 actually with wrong IV (and thus MAC check fails). So, packets
1826 that are in queue should be encrypted when they are sent to
1827 the wire and not when they put to the queue.
1829 However, the problem is that the current system has not been
1830 designed to work that way. Instead, the packet is encrypted
1831 as soon as possible and left to the queue. The queue is then
1832 just purged into wire. There won't be any fixes for this
1833 any time soon. So, the current semantic for packet sending
1836 o If you send packet to remote host and do not force the send
1837 (the packet will be in queue) then all subsequent packets to the
1838 same remote host must also be put to the queue. Only after the
1839 queue has been purged is it safe again to force the packet
1842 o If you send all packets immediately then it safe to send
1843 any of subsequent packets through the queue, however, after
1844 the first packet is put to queue then any subsequent packets
1845 must also be put to the queue.
1847 Follow these rules and everything works fine.
1849 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Added new function silc_server_remove_clients_by_server to
1852 remove all client entries from ID list when the server connection
1853 is lost. In this case it is also important to invalidate all
1854 client entires as they hold the invalid server entry. This
1855 fixes fatal bug when server has lost connection and will reconnect
1858 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Made some sanity checks to silc_server_daemonise like to check
1861 whether the requested user and group actually exists.
1863 * Added sanity check to SKE's silc_ske_responder_finish to check
1864 that the public and private key actually is valid.
1866 * Invalidate the client's nickname when receiving Replace ID
1867 packet and the Client ID is being replaced. This means that the
1868 server will query the nickname if someone needs it (client)
1871 * Sort the ID Cache in client library when the ID Cache data
1872 has changed (needs sorting).
1874 * Do not allow for SILC client to create several connections to
1875 several servers. The client does not support windows right now
1876 and generating multiple connections causes weird behaviour.
1878 Irssi-silc client does support windows and can handle several
1879 connections without problems, see: www.irssi.org and SILC plugin.
1881 * Fixed some places where client was added to the IDList. The
1882 rule of thumb is following (in order to get everything right):
1883 If the client is directly connected local client then the
1884 `connection' argument must be set and `router' argument must be
1885 NULL to silc_idlist_add_client function. If the client is not
1886 directly connected client then the `router' argument must
1887 bet set and the `connection' argument must be NULL to the
1888 silc_idlist_add_client function.
1890 * The funtion silc_server_packet_send_local_channel actually did
1891 not check whether the client was locally connected or not. It
1892 does that now. Fixed a bug related to LEAVE command.
1894 * Fixed Remove Channel User payload parsing bug in server's
1895 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1897 * The server's silc_server_save_channel_key now checks also the
1898 global ID list for the channel as it might not be in the local
1899 list. Fixed a bug related to LEAVE command.
1901 * Is this the end of the [<unknown>] buglet that has been lurking
1902 around for a long time? A little for loop fix in server's
1903 silc_server_command_whois_parse that is used by both IDENTIFY
1904 and WHOIS command. At least, this was a clear bug and a cause
1905 of one type of [<unknown>] buglet.
1907 * WHOIS and IDENTIFY commands call the function
1908 silc_server_command_[whois/identify]_check function even if
1909 we are not router server.
1911 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Added --with-gmp configuration option. If set the GMP
1914 is always compiled in the SILC source tree. If not set then
1915 it is checked whether the system has the GMP3 installed. If
1916 it has then the GMP won't be compiled (the system's headers
1917 and library is used), if it doesn't have it then the GMP is
1918 compiled in the SILC source tree.
1920 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Changed RSA private exponent generation to what PKCS #1
1923 suggests. We try to find the smallest possible d by doing
1924 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1925 not security fix but optimization.
1927 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Added new config entry [Identity] to fork the server and run
1930 it as specific user and group. A patch from Bostik.
1932 * Imported Dotconf configuration library into lib/dotconf.
1933 This will be used to create the SILC configuration files later.
1934 It will appear in the distsribution after this commit.
1936 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * A big code auditing weekend happening. Auditing code for
1939 obvious mistakes, bugs and errors. Also, removing any code
1942 Removed files for being obsolete:
1944 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1945 inline in the file lib/silcutil/silcbuffer.h)
1947 o lib/silcutil/silcbufutil.c (the header has inline versions)
1949 Changed code to fix possible error conditions:
1951 o The buffer formatting routines now check that the destination
1952 buffer really has enough space to add the data. This applies for
1953 both buffer formatting and unformatting
1954 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1955 unformatting was changed to accomodate following rules:
1956 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1957 sent to the function while XXX_*STRING will not allocate or copy
1958 the data into the buffer. Instead it sets the pointer from the
1959 buffer into the pointer sent as argument (XXX_*STRING used to
1960 require that the pointer must be allocated already). This change
1961 makes this whole thing a bit more consistent and more optimized
1962 (note that the data returned in the unformatting with XXX_*STRING
1963 must not be freed now). The routines return now -1 on error.
1965 o Tried to find all code that use buffer_format and buffer_unformat
1966 and added return value checking to prevent formatting and
1967 especially unformatting errors and possible subsequent fatal
1970 o Changed ske->x and ske->KEY to mallocated pointers in
1971 lib/silcske/silcske.h. Fixed possible data and memory leak.
1973 o Added return value checking to all *_parse* functions. Fixed
1974 many memory leaks as well.
1976 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1977 so that buffer overflows would not happen. All code now also
1978 checks the return value as it can fail.
1980 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Added reconnection support to server if the normal server looses
1983 its connection to the router (for example if router is rebooted).
1984 The server performs normal reconnection strategy implemented
1985 to the server. Affected file silcd/server.c.
1987 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Added new packet type SILC_PACKET_SET_MODE that is used to
1990 distribute the information about changed modes (for clients,
1991 channels and clients channel modes) to all routers in the
1992 network. Updated the protocol specification accordingly.
1994 Added functions into silcd/packet_send.c and
1995 silcd/packet_receive.c: silc_server_send_set_mode,
1996 silc_server_set_mode.
1998 Added new files silcmode.[ch] into lib/silccore that implements
1999 the encoding and decoding of Set Mode Payload. Added new type
2000 SilcSetModePayload. Moved the definitions of different modes
2001 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2003 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Oops, a little mistake in server's connection authentication
2006 protocol. The protocol is not ended with FAILURE but with
2007 SUCCESS if the authentication is Ok. :) Affected file is
2010 * Implemented NICK_CHANGE notify handling in server in the file
2011 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2012 the local clients on the channel. After the changing nickname
2013 in router environment snhould work and the [<unknown>] nickname
2014 should appear no more.
2016 The silc_server_replace_id function that receives the Replace ID
2017 payload now sends the NICK_CHANGE notify type also in the file
2018 silcd/packet_receive.c
2020 * Changed WHOIS and IDENTIFY command to support the maximum amount
2021 of arguments defined in protocol specs (3328 arguments). This
2022 fixed a bug that caused problems when there were more than three
2025 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Added extra parameter, command identifier, to the
2028 silc_client_send_command so that explicit command identifier
2031 Changed that ID list routines uses specific command identifier
2032 when sending WHOIS/IDENTIFY requests to the server so that they
2033 can be identified when the reply comes back.
2035 Affected files lib/silcclient/command.[ch],
2036 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2038 * Added `sender' argument to silc_server_packet_send_to_channel
2039 to indicaet the sender who originally sent the packet to us
2040 that we are now re-sending. Ignored if NULL. Affected file
2041 silcd/packet_send.[ch].
2043 * Added some server statistics support in silcd/server_internal.h
2044 SilcServerStatistics structure and around the server code. Also
2045 send some nice statistics information when client is connecting
2048 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Fixed channel ID decoding in server's JOIN command reply in
2051 silcd/command_reply.c
2053 * Fixed braodcasting of replace ID payload to not to send it if
2054 we are standalone server in silcd/packet_receive.c.
2056 * Fixed all channel message sending routines to not to send
2057 packets to clients that has router set, since they are routed
2058 separately in the same function earlier. Affects file
2059 silcd/packet_send.c and all channel packet sending functions.
2061 * In USERS reply, res_argv[i] are not allocated, the table
2062 is allocated. Thus changed that free the table, not its
2065 * In server's whois_check and identify_check if the client is
2066 locally connected do not send any WHOIS commands - they are not
2069 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Fixed some minor bugs in client when sending WHOIS command. The
2072 arguments was in wrong order.
2074 * Removed statis function add_to_channel from server in
2075 silcd/command.c that was previously used with the joining but
2078 * Tested USERS command in router environment successfully with two
2079 routers, two servers and two clients.
2081 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Reorganized the USERS command and command reply in client library
2084 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2085 When the command is given by user we register a pending command
2086 callback that will reprocess the command after the reply has been
2087 received from the server. When reprocessing the packet we then
2088 display the information. Thus, the USERS information is displayed
2089 now in the command callback instead of in the command reply
2090 callback. The processing of the command is same as previously
2091 when server has sent the command reply in the JOINing process.
2093 * Added to USERS command in silcd/command_reply.c to join the client,
2094 we didn't use to know about, to the channel after we've created
2095 a client entry for it. Also, for clienet we did know already still
2096 check whether it is on the channel or not and add it if not.
2098 * Removed silc_server_command_join_notify as the function and its
2101 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Changed the client's pending command handling to the same as the
2104 server's pending command handling. It is also now possible to
2105 execute command reply functions from other command reply
2106 function as the function callbacks for commands and command
2107 replies are one and same. The pending commands are not static
2108 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2109 in client connection context. Thus, pending commands are server
2110 connection specific as it is convenient.
2112 Changed the function silc_client_command_pending and
2113 silc_client_command_pending_del and added new function
2114 silc_client_command_pending_check. Removed the
2115 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2118 * Added cmd_ident, current command identifier, to the client
2119 connection context in lib/silcclient/client.h to keep track on
2120 command identifiers used in command sending. Client's command reply
2121 function handling now supports the mandatory command identifiers.
2123 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2124 funtions in client to fully support pending command callbacks.
2126 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2127 as one of the arguments to the application in the command reply
2130 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2131 before first releasing SILC but came back. Now it is removed again
2132 and should come back nomore. The FORWARDED flag was used only
2133 by the JOINing procedure by forwarding the command packet to router.
2134 Now, the JOINing procedure has been changed to more generic (due
2135 to various router environment issues) and FORWARDED is not needed
2136 anymore for anything. The protocol specification is yet to be
2139 Now, removed silc_server_packet_forward from server and the flag
2140 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2142 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Renamed NAMES command to USERS command. The NAMES was named that
2145 due to historical reasons. Now it is renamed. Also, rewrote
2146 parts of the USERS command. The nickname list is not sent anymore
2147 by the server. Only Client ID and mode lists are sent in the USERS
2148 command. Changed this also to the protocol specification.
2150 The client now resolves the names and stuff after it receives
2151 the USERS list from the server when joining to the channel.
2153 * WHOIS and IDENTIFY commands has been changed to support multiple
2154 Client ID's per command. One can now search for multiple users
2155 in the network by sending only one WHOIS or IDENTIFY command.
2156 Changed the code and the protocol specifications.
2158 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2159 uses silc_server_command_whois_parse to parse the request. */
2161 * If normal server, do not parse the WHOIS and IDENTIFY requests
2162 before sending it to the router. Saves some time.
2164 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Fixed JOIN command on client library. Wrong number of arguments
2167 used to crash the client.
2169 * Added silc_server_channel_has_global function to check whether
2170 channel has global users or not.
2172 * Added silc_server_channel_has_local function to check whether channel
2173 has locally connected clients on the channel.
2175 * The silc_server_remove_from_one_channel now checks whether the
2176 channel has global users or not after given client was removed from
2177 the channel. It also checks whether the channel has local clients
2178 on the channel anymore. If it does not have then the channel entry
2179 is removed as it is not needed anymore.
2181 * The silc_server_notify now checks on JOIN notify whether the joining
2182 client is one of locally connected or global. If it is global then
2183 the channel has now global users on the channel and that is marked
2184 to the channel entry. Also, it now saves the global client to
2185 global list who is joining and JOINs it to the channel. This is
2186 for normal server, that is.
2188 Changed silc_server_send_notify_on_channel,
2189 silc_server_packet_relay_to_channel and
2190 silc_server_packet_send_to_channel check if we are normal server
2191 and client has router set (ie. global client) do not send the
2192 message to that client, as it is already routed to our router.
2194 * Implemented LEAVE notify type handling in silc_server_notify
2197 * Tested LEAVE command in router environment successfully. Tested
2198 with two routers, two servers and two clients.
2202 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2204 * Implemented SIGNOFF notify type handling in silc_server_notify
2207 * silc_server_remove_id now removes the client entry from all channels
2208 it has joined and thusly sends SIGNOFF notify type.
2210 * Rewrote the NAMES list generation in server by removing two excess
2211 loops. The lists are created now inside one loop.
2213 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * silc_server_remove_channel_user checks now also global list
2216 for channel and client.
2218 * silc_server_new_channel_user checks now both local and global
2219 list for channel and client. Fixed a bug in client id decoding.
2220 Used to decode wrong buffer.
2222 * silc_server_channel_message checks now both local and global
2223 list for channel entry.
2225 * Tested channel joining (hence JOIN) in router environment
2226 successfully. Tested with two routers, two servers and two
2229 * Tested channel message sending in router environment successfully.
2231 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Added silc_server_save_channel_key into server.[ch] to save the
2234 received channel key in Channel Key payload processing. It is
2235 also used in JOIN command reply handling.
2237 Equivalent function silc_client_save_channel_key added into
2238 client.[ch] into client library.
2240 * Changed JOIN command reply to send information whether the channel
2241 was created or not (is existing already) and the channel key
2242 payload. Changed protocol specs accordingly.
2244 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2245 the request was sent by ID and not by nickname. Crashed on
2248 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2251 now correctly save the received data.
2253 * silc_server_free_sock_user_data now notifies routers in the
2254 network about entities leaving the network.
2256 At the same time implemented functions silc_server_remove_id
2257 and silc_server_send_remove_id to receive and send REMOVE_ID
2258 packets. The packet is used to notify routers in the network
2259 about leaving entities. The ID removed will become invalid in
2262 * Added function silc_idlist_del_server into server. Removes and
2263 free's server entry from ID list.
2265 * silc_server_private_message function now checks, if we are router,
2266 that the destination ID really is valid ID, naturally.
2268 * In router when NEW_ID packet is received (for new client) the
2269 hash of the Client ID is saved in the ID Cache but the
2270 client->nickname is set to NULL, instead of putting the hash
2273 IDENTIFY command now also checks that client->nickname must be
2274 valid. If it is not if will request the data from the server who
2275 owns the client. Added new function
2276 silc_server_command_identify_check.
2278 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2279 to set the command to already allocated Command Payload.
2281 * Tested private message sending in router environment with two
2282 routers, two servers and two clients. Fixed minor bugs and now
2285 * Fixed segfault from client's NAMES command. Used to crash if
2288 * Forwarded packets must not be routed even if it is not destined
2289 to the receiver. Changed server code comply with this.
2291 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Added `require_reverse_mapping' boolean value to ServerParams
2294 structure. If TRUE (not default) the server will require that
2295 the connecting host has fully qualified domain name.
2297 If the reverse mapping is not required and hostname could not be
2298 found the IP address is used as hostname.
2300 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Implemented version string checking to both client and server.
2303 The check is incomplete currently due to the abnormal version
2304 strings used in development version of SILC.
2306 * Changed all command functions in server to use the new
2309 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Changed char *data to unsigned char *data in ID Cache system to
2312 support binary data as ID Cache data. Changed code to support
2313 binary data in lib/silccore/idcache.c.
2315 * Renamed silc_server_packet_relay_command_reply to
2316 silc_server_command_reply as it is normal packet receiving
2317 function. Rewrote the function to accept command replys for
2318 servers and not only for clients.
2320 * Mark remote router always as registered server if we are connecting
2321 to it. Otherwise, commands sent by the router to us are ignored.
2323 * All ID List find routines now returns the ID Cache Entry pointer
2324 as well if requested.
2326 * WHOIS command works now in router environment, tested with two
2327 routers, two servers and two clients.
2329 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2330 in router environment (as it is almost equivalent to WHOIS) but
2331 hasn't been tested thoroughly. Added new functions:
2333 silc_server_command_identify_parse
2334 silc_server_command_identify_send_reply
2335 silc_server_command_identify_from_client
2336 silc_server_command_identify_from_server
2338 * Disabled route cache adding because adding two different ID's with
2339 same IP replaces the old cache entry thus giving wrong route.
2340 The entry->router->connection is always the fastest route anyway
2341 so route cache may not be needed. Of course, new routes maybe
2342 established after receiving the ID when the entry->router->connection
2343 might not be anymore the most optimal.
2345 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Add route cache for received ID for fast routing.
2349 * Added silc_server_packet_route to route received packet on router
2350 that is not destined to us.
2352 * Renamed silc_server_get_route to silc_server_route_get.
2354 * Added id_string and id_string_len fields into SilcServer to
2355 include encoded ServerID for fast comparing without excess
2356 encoding of the ID's.
2358 * Cleaned up WHOIS command on server side. Added following static
2361 silc_server_command_whois_parse
2362 silc_server_command_whois_check
2363 silc_server_command_whois_send_reply
2364 silc_server_command_whois_from_client
2365 silc_server_command_whois_from_server
2367 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2368 arguments in command replies. All command functions should be
2369 updated to use this macro.
2371 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Minor typo fixes on command reply handling on server.
2375 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Added silc_server_command_add_to_channel internal routine to add
2378 the client to the channel after router has created the channel and
2379 sent command reply to the server.
2381 * Added generic silc_server_send_command to send any command from
2384 * Use static buffer with ID rendering instead of duplicating data.
2386 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Fixed a channel user mode bug when joining to a channel server gave
2389 everybody channel founder rights, oops.
2391 * We mark ourselves as the router of the incoming server connection
2392 if we are router ourselves. This way we can check in some packet
2393 sending functions whether it is locally connected server. For
2394 incoming router connections we put NULL.
2396 * For router sending packets locally means now always sending the
2397 packet cell wide; to local clients and local servers. For normal
2398 server sending packet locally means sending it to only local
2401 * Fixed the JOIN command to really work in router environment. If the
2402 channel is created it is always created by the router. Router is
2403 also responsible of making the initial joining to the channel,
2404 sending JOIN notify to the sending server and distributing
2405 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2406 does not exist server doesn't do anything else but forward the
2407 command to the router which performs everything.
2409 * Added silc_server_send_channel_key function to send the Channel Key
2412 * Added silc_server_create_channel_key to create new channel key. The
2413 channel key is now re-generated everytime someone joins or leaves
2414 a channel, as protocol dictates. Note: channel->key_len is the
2417 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2420 packet_receive.[ch] to separate packet sending and receiving
2421 routines. The server.[ch] now includes everything else including
2422 actual packet processing (writing and reading data) and other
2425 Renamed silc_server_private_message_send_internal to
2426 silc_server_send_private_message. The routine is still though
2427 used only to relay private messages as server does not send
2428 private messages itself.
2430 Renamed silc_server_new_channel to silc_server_create_new_channel
2431 and added new function sicl_server_new_channel that handles the
2432 incoming New Channel packet. Added also new sending function
2433 silc_server_send_new_channel to send New Channel Payload.
2435 * Added new function silc_server_notify to process incoming notify
2436 packet to the server/router. Server may then relay the notify
2437 to clients if needed.
2439 * Added new function silc_server_new_channel_user to process incoming
2440 New Channel User packet. Router will redistribute the packet and
2441 send JOIN notify to its local clients and locally connected servers
2442 if needed. Normal server will send JOIN notify to its local client
2443 on same channel when received this packet. Added also corresponding
2444 sending function silc_server_send_new_channel_user to sent the
2447 * Added boolean route argument to send_notif_to_channel and
2448 packet_send_to_channel functions to attempt to route the packet
2449 if it is TRUE and send only locally if it is FALSE.
2451 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * silc_server_replace_id now broadcasts the received replace ID
2454 packet if it is not broadcast packet already. The router must
2455 broadcast to inform other routers about changed ID.
2457 * Added backpointer to server's router into SilcServer context in
2458 silcd/server_internal.h.
2460 * Fixed silc_server_packet_broadcast to send correct broadcast
2463 * The channel key is now distributed to the local client as soon
2464 as it is received from the router (in router environment) so that
2465 no other packet may be sent for the channel until client has
2468 * silc_server_remove_channel_user now broadcasts the received
2469 Remove Channel User packet if it is not broadcast packet already.
2470 The router must broadcast to inform other routers about removed
2473 * Added users field into SilcPacketContext that is a reference count
2474 of the context. One can increase the reference count by calling
2475 silc_packet_context_dup which is now changed to just increase the
2476 reference count instead of duplicating the data. The reference
2477 count is decresed by calling silc_packet_context_free that will
2478 free the data after the reference count hits zero.
2480 For now on the packet context and everything allocated into it
2481 (including the raw packet from network) must be freed by calling
2482 the new silc_packet_context_free function. Added also new function
2483 silc_packet_context_alloc that must be used now to allocate the
2484 context. This also means that if a routine is asynchronous from
2485 silc_[client/server]_packet_parse_type the packet context must
2486 be duplicated by calling silc_packet_context_dup. Otherwise it
2487 gets free'd after silc_[client/server]_packet_parse_type returns.
2488 Also, one must remember that if packet is duplicated then its
2489 reference count must be decresed by calling the free function as
2490 many times as it was duplicated.
2492 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2493 from both client and server.
2495 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Made joining to a channel working in router environment.
2499 * Cleaned up JOIN command on server side and create function
2500 silc_server_command_join_channel internal routine to make the
2503 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Changed silc_command_pending list to SilcDList. Also, added
2506 `ident' field to SilcServerCommandPending structure to identify
2507 the reply and to call correct callback.
2509 Added silc_server_command_pending_check function to replace the
2510 corresnponding macro. The silc_command_pending list is not
2513 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2514 to set identifier to previously allocated Command Payload. It
2515 is used to set identifier for command when resending Command
2518 * Added silc_command_payload_encode_payload to encode Command
2519 Payload buffer from SilcCommandPayload structure.
2521 * Added silc_argument_payload_encode_payload to encode Argument
2522 payload buffer from SilcArgumentPayload structure.
2524 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Changed WHOIS command to support router connection on server side.
2527 The whois request is always sent to router unless the server is
2528 standalone server. After server has received the reply from the
2529 router will it send the reply to the client.
2531 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2532 broadcast received broadcast packet. The function is used only
2533 by router. The broadcast packet is always sent to the router's
2536 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2537 render given ID to printable string, for log files for example.
2539 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2541 * Made basic router to router connections working. At least they
2542 can now connect to each other but nothing really works the way
2543 they are supposed - yet.
2545 * Added new initiator token to RouterConnection configuration
2546 file in silcd/serverconfig.[ch]. It is used to tell whether we
2547 are the initiator to the remote router or whether we'll expect
2548 the other end to connect.
2550 * Moved registering of listener task to silc_server_init, hence
2551 the server starts listenning as soon as it is run, even if it
2552 does not have connections to other routers. Let's see how well
2555 * Changed default connection retry timeouts for more suitable in
2558 * Removed cipher and such arguments from silc_idlist_add_client
2559 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2560 Added new function silc_idlist_add_data to add the keys and stuff
2563 * Added SilcIDListData structure and added it to SilcClientEntry
2564 and SilcServerEntry as their first field in the structure. This
2565 way we can explicitly cast the ID entries to the SilcIDListData
2566 structure and get common data for the entries. In past, we had
2567 to first check what type of connection it is and then cast it to
2568 correct ID entry type. Now, we can directly cast the opaque
2569 pointer to the SilcIDListData (no matter what ID entry it actually
2570 is) and get the data needed.
2572 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2575 in some circumstances even if threre were timeout tasks, though not
2576 IO tasks, but tasks anyway. Now fixed.
2578 * Defined SilcServerConnection structure to hold connection specific
2579 stuff about directly connected servers and routers. The definition
2580 is currently in silcd/server_internal.h. I thought about having
2581 a bit more important role fro this struct but for now it is used
2582 only when connecting to other server (or router actually).
2584 * Added connecting retry support in server when connecting to
2585 router(s). The retry feature implement exponential backoff
2586 algorithm. Also, added SilcServerParams structure to hold default
2587 parameters for server. For now, it include these retry settings
2588 and are hard coded. After server is moded to be as Silc Server
2589 Library this structure will be more important.
2591 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Changed client librarys channel->clients table to SilcList and
2594 changed code accordingly.
2596 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Changed client's channel table to SilcList and changed code
2599 accordingly. Also changed SilcChannelClientEntry to include back-
2600 pointer to the channel so that client entry can use that structure
2601 as list as well and we have fast cross-reference to the channel.
2602 This change dramatically decreased the complexity of channel
2603 handling with client entry and vice versa (removed one extra
2604 loop when searching for channel entry from many functions).
2606 * Changed server->sim from table to SilcDList and changed code
2609 * NAMES command can now be used from user interface. It will show
2610 the user list on the channel, neatly.
2612 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2613 Code now saves realname of the user if it becomes available.
2615 * Renamed configure.in to configure.in.pre and made ./prepare
2616 script to automatically add correct version string to
2617 configure.in which it creates from configure.in.pre.
2619 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * NAMES command reply now shows users mode with the nickname when
2624 * Moved silc_client_ch[u]mode[_char] functions from
2625 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2626 place sucks, they are utility functions and should be in some
2629 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2631 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2634 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Added TRQ (efficient deque and list library) into lib/trq. This is
2639 a very good list library that is currently used in the SILC. Defined
2640 SilcList API over the library because I didn't like the API very
2641 much. See lib/trq/silclist.h for the API and examples of how to
2642 use the API. Fixed various places in the code to use the new
2643 SilcList API. The SilcList is meant for lists that has a structure
2644 already defined as a list. It is not suitable to add just some
2645 context to the list (in TRQ, the context is the list actually).
2647 So, I defined SilcDList that can be used for the purpose where
2648 predefined list structure does not exit. This can be used as
2649 such list. Now some context just can be added to the SilcDList.
2650 Currently this list is not used in the SILC just yet, though there
2651 are a lot places where this can replace dynamically allocated
2652 tables and I will fix these places, later, to use SilcDList.
2653 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2654 and use TRQ internally).
2656 Also fixed some annoying warning messages that the original TRQ
2657 code generated. Also minor changes to TRQ's Makefile.in.
2659 * Added support for querying by Client ID to both WHOIS and
2660 IDENTIFY commands into server, as required by the protocol.
2662 * Removed method function pointers from SilcBuffer structure. They
2663 weren't used to anything and just increased the context size for
2664 no good reason. This change also made silc_buffer_alloc and
2665 silc_buffer_free functions inline functions.
2667 * Disabled command flooding detection support until it's fixed so
2668 that it accepts commands in but does not execute them more than once
2671 * Added silc_net_localhost(), to return local hostname, into
2672 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2673 that must be initialized before calling silc_client_init.
2675 * Added new function: silc_server_send_notify_on_channels to send
2676 notify messages to all channels client has joined. It is assured
2677 that the message is sent only once per client.
2679 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2680 lib/silcutil/silcutil.[ch] as silc_format function. The new
2681 function is generic and is used by server as well, not only by
2682 the logging routines.
2684 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2685 the provided version string was not acceptable. Added new function:
2686 silc_ske_check_version into lib/silcske/silcske.h. The function
2687 must be implemented by the application (client or server) and it
2688 does not reside in the SKE library. The function checks the version
2689 string remote end sent.
2691 * Added back pointers (to opaque context and to SilcSocketConnection)
2692 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2694 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2695 duplicate packet context structure.
2697 * Changed `notify' client operation to send same arguments as client
2698 receives from server except for ID's. ID's are mapped to correct
2699 ID entry and that is returned. Also, if channel entry is not sent
2700 by server but the notify is for channel the channel entry is sent
2701 to application (otherwise application doesn't know that it is for
2702 channel (library gets it from packet's Destination ID)).
2704 * Added silc_client_remove_from_channels into client library to
2705 remove a client from all channels it has joined to. Used when
2706 received SIGNOFF notify from server. Added also new function
2707 silc_client_replace_from_channels to replace old ID entry with
2708 new ID entry on all channels. Used when received NICK_CHANGE
2711 * Fixed ID Cache list handling in silc_idlist_get_client in
2712 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2713 to get (or query) client by ID.
2715 * Updated TODO list.
2717 * Added connection authentication status message defined by the
2718 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2719 support for these into the code in client and server side.
2721 * Added generic function silc_client_send_command to send any command
2722 with variable argument list. Application should use this function
2723 to send commands if the command functions provided by the library
2724 does not suite for the application's user interface needs.
2726 * Added new `failure' client operation. Application is notified about
2727 received failure packet if client is executing a protocol. In this
2728 case the protocol's execution has failed.
2730 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2731 is required by the protocol.
2733 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2734 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2737 * Added status flag to SilcSKE object to indicate realtime status
2738 of the SKE protocol.
2740 * Application receives now exactly same command reply arguments as
2741 the library receives from server. However, if ID is received the
2742 corresponding ID entry is returned to the application (eg. Client
2743 ID is mapped to correct SilcClientEntry entry and that is returned).
2744 Changed command_reply client operation due to this change.
2746 * Changed all ID's in commands and in command replys as ID Payloads.
2747 Change affected both client and server side codes.
2749 All ID's sent in SILC network (with execption of ID's in SILC
2750 Packet header) are sent in ID Payload to support variable length
2753 * Server now notifies nick changes and notifies all clients on
2754 the channels about the new nickname (about the new Client ID,
2757 * Implemented CMODE command to change channel modes. Supports all
2758 channel modes defined by the protocol specs except ban and invite
2759 lists. (Also, private channel key mode is supported but support for
2760 setting private channel key in client is missing, thus, this mode
2761 has no effect on client side (except that server requires that the
2762 client uses private channel key and normal channel traffic does not
2765 Also, invite mode works per se, but INVITE command does not work
2766 yet correctly, so you can set channel as invite only channel but
2767 inviting clients to the channel does not work (it is yet to be
2768 thought what's the best way to do it).
2770 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2771 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2772 Implemented CUMODE command to change user's mode on the channel.
2773 Supports all modes defined by the protocol specs.
2775 * Added NAMES command reply to return users modes on the channel.
2777 * Removed unnecessary and slow ciphers from lib/silccrypt.
2779 * Set SO_KEEPALIVE option to connection sockets by default.
2781 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2783 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2784 redefined the Notify Payload into protocol specs.
2786 * Added silc_id_payload_parse_id to get ID directly from raw
2789 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2792 accept searching by Client ID as well.
2794 * Added support for LEAVE and SIGNOFF notify types in client library.
2796 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2797 to parse ID Payload from raw data.
2799 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added flags parameter into silc_ske_assemble_security_properties
2802 function in lib/silcske/silcske.[ch].
2804 * Changed notify client operation to fit better for notify messages
2805 sent by server. The notify payload received from server is now
2806 passed to the application (after parsing it to SilcNotifyPayload).
2807 It is application's responsibility to retrieve the arguments
2808 from the payload and show the message the way it wants. The message
2809 sent by server is implementation specific.
2811 * Changed public keys to comply with the protocol specification.
2812 Old public keys are not supported anymore and are not compatible.
2814 * Removed nickname from Channel Payload as the latest draft removed
2815 it. The client must resolve the nickname from the NAMES command
2816 reply received when it joined the channel.
2818 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2820 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Fixed some errors in protocol specification drafts.
2824 * Created lib/silccore/silcnotify.c to implement Notify Payload
2825 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2826 generic payloads described by protocol specifications. The file
2827 includes implementations for ID Payload and Argument Payload.
2829 * Changed Command Payload implementation to use the new Argument
2830 Payload. Changed command_xxxx_payload to command_payload_xxxx
2831 to comply with SILC coding conventions.
2833 * Added suppport for Argument Payload handling in Notify Payload
2834 implementation as protocol requires it. Added the new support
2835 into server and client lib as well.
2837 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added support for multiple nicknames on same channel. [n] is
2840 added locally to the nickname if there are more than one same
2841 nicknames on the channel.
2843 * Server now sends all nicknames that matched WHOIS request.
2844 Client also shows the list received from server.
2846 * Added TOPIC command to client side. User can now set and show
2847 current topic on channel.
2849 * Added MOTD command to client and server. Also, server sends the
2850 motd when client connects to the server.
2852 * Changed version strings to comply ISO 8601.
2854 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Fixed protocol error handling in client library. It should now
2857 cope even if the SKE fails for some reason.
2859 * Made new protocol specification drafts for submitting to IETF.
2861 * Implemented TOPIC command to server in silcd/command.c.
2863 * Added two new notify types into lib/silccore/silcnotify.h:
2864 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2865 notify nickname change and topic setting/change on a channel.
2867 * API change of command_reply operation in client library. The
2868 application gets now the status type received from server as well.
2870 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2874 * Cras fixed and optimized the packet handling even further and
2875 it should work now. Minor change to the prototype of function
2876 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2878 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Added new function into lib/silcutil/silcschedule.[ch]:
2881 silc_schedule_with_fd to select() a specified fd. The function
2882 returns after timeout expires or data arrives or goes. The
2883 function is used by packet routines to wait that all data is
2884 received from network.
2886 * Fixed data reading from network in lib/silccore/silcpacket.c.
2887 The code now assures that all data is read from the fd and then
2888 continues packet processing. This was a bug fix since the code
2889 used to drop some data in some circumstances.
2891 * Added new function into lib/silcclient/client.[ch]:
2892 silc_client_start_key_exchange to start key exchange after
2893 connection has been established to server. The code internally
2894 now uses this funtion but its main purpose was to provide it
2895 for applications that perform their own connecting. After
2896 application has created a connection it merely calls this
2897 function to start the key exchange between client and server.
2898 The library takes care of everything else after that.
2900 Updated also lib/silcclient/README to explain the usage of
2903 * Do not send to application information that connection has
2904 been established. Application gets notified it by connect
2907 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Applied cras's patch to add silc_schedule_one function. The
2910 function runs scheduler once and returns.
2912 * Fixed the scheduler after cras messed it up. The timeout
2913 handling works now as it's supposed to work.
2915 * Added into lib/silccore/ silcnotify.h to include notify
2916 message types support. Changed silc_server_send_notify*
2917 functions, in server.[ch], to support those new notify types.
2918 Added the support for the notify types into client library,
2919 as well. Added new notify client operation into ops.h in
2922 * Changed silc_server_packet_send_to_channel to send normal
2923 packets instead of just channel message packets. The function
2924 is now used to send the notify packets to channels. It is not
2925 used to send channel message packets anymore, as server never
2928 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2929 va_arg()s as it seems to require it nowadays. I guess, if SILC
2930 is compiled with older va_arg() the new code should work anyway.
2932 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Splitted core library. Core library (lib/silccore) includes
2935 now only SILC protocol specific core (and common) components.
2936 Created new utility library (lib/silcutil) that includes more
2937 generic purpose stuff. The stuff for util library was taken
2938 from the old core library. This was minor and easy split.
2940 * Created SILC Client Library (lib/silcclient) that includes
2941 implementation of the SILC client without user interface. This
2942 was major move from silc/ directory. The code has been changed
2943 so that it is transparent towards the user interface. The
2944 silc/ directory includes now the same user interface as before
2945 and it uses the new client library. Read lib/silcclient/README.
2946 Basicly, the client library performs everything else related
2947 to SILC except user interface handling. Also, configuration
2948 files are considered to be part of user interface and library
2949 does not handle them.
2951 This change also changed a lot of structures, function naming etc.
2952 Most important change was that SilcClientWindow object was
2953 renamed to SilcClientConnection in the client library. Created
2954 also new file lib/silcclient/ops.h. Also added new files
2955 silc/local_command.[ch] and silc/client_ops.[ch].
2957 All these changes were made to make it easier for user interface
2958 designers to create what ever user interface for the SILC client
2961 It is also expected that the server will be moved to lib
2962 directory as well and SILC Server Library will be created;
2963 sometimes in the future.
2965 * Removed Local commands from lib/silccore/silccommand.h as
2966 they are application specific and new client library does not
2967 handle any of those anymore.
2969 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2970 old client implementation in silc/.
2972 * Added support for callback functions in SILC_LOG_* macros.
2973 Application can now set its own callbacks that will be called
2974 instead of using the default functions that will always print
2975 the debug messages to stderr (or stdout). Also, debugging can
2976 now be disabled by setting silc_debug to FALSE and re-enabled by
2977 setting it to TRUE. Note, that logging will still work even
2978 if debugging is disabled.
2980 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2981 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2982 silc_log_reset_debug_callbacks.
2984 * To enable debugging in silc client one must give now -d
2985 option on command line.
2987 * Changed silc_schedule_init to automatically allocate task queues
2988 if they are not allocated before calling it.
2990 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added GMP 3.1 into math library.
2994 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2997 a channel in SILC network. The packet is used by servers and
2998 routers to notify other routers that user has left a channel.
2999 This little feature was missing until now. Added the feature
3000 to protocol specification as well.
3002 Added functions: silc_server_send_remove_channel_user and
3003 silc_server_remove_channel_user into server.[ch].
3005 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3006 lib/silccore/silcpacket.h. However, they are not implemented
3009 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Fixed joining to a channel and sending channel messages
3012 between server and router. The channel message sending should
3013 now work inside a cell.
3015 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Fixed the private message sending between server and router.
3018 The private message sending should now work inside a cell.
3020 * Added silc_server_replace_id into server.[ch] to replace
3021 existing ID in the SILC network.
3023 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3024 and silc_idlist_replace_server_id into idlist.[ch] in server.
3026 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Fixed the server to server connections. Server can again now
3029 connect to router. Router to router connections probably does
3032 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Added dynamic protocol registering support. Now protocols can
3035 registered and unregistered on the fly. Patch by cras.
3037 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Added lib/contrib directory to hold routines that some platforms
3040 don't have but are needed by SILC.
3042 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3043 into lin/contrib to provide getopt() and getopt_long() for
3044 those who don't have it.
3046 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added AWAY command to client. When away message is set and
3049 client receives a private message packet the client automatically
3050 replies to the sender with the away message.
3052 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3053 bug seemed to be the cause of recent problems when compiling
3056 * Added version detection support to SKE protocol specification
3057 and added the new changes to the SKE implementation as well.
3058 There were other minor changes in the SKE protocol as well.
3060 Many changes in lib/silcske/silcske.[ch] and in
3061 lib/silcske/payload.[ch].
3063 * Added ^U functionality, clear input line. Patch from cras.
3065 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Mainly small bugfixes on core library. Fixed some debugging
3068 logging and buffer overflow in silclog.c.
3070 * Updated config.sub and config.guess on the distribution tree.
3072 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added command lagging support in server. Client may execute
3075 commands now only once in two seconds.
3077 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Optimized packet reception. MAC computation and checking is now
3080 also more optimized. A lot previously duplicated code is now
3081 used as generic by both client and server.
3083 * Fixed key pair generation in clientutil.c
3085 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Added into lib/silccore/silcbufutil.[ch] new function;
3088 silc_buffer_realloc.
3090 * Moved generic packet sending/encryption functions to
3091 lib/silccore/silcpacket.[ch] from client and server. Some
3092 rewriting of the functions.
3094 * Moved all generic packet reception/decryption functions to
3095 lib/silccore/silcpacket.[ch] from client and server. The
3096 packet processing is now much cleaner in both client and server.
3097 These were major changes in both client and server.
3099 * Created many common functions in server to do packet sending.
3100 Previously code were duplicated a lot, this has been removed
3103 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Rewrote major parts of the ID cache system. Don't know
3106 whether it is better now or not but at least the API is more
3109 * Major rewrite on ID cache stuff on client because of the ID
3110 cache API changes. Added idlist.c to client.
3112 * Also major rewrite on ID cache stuff on server as well.
3113 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3114 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3115 in hand, instead they are all put into the ID cache system now.
3116 All server_idlist_* routines uses ID cache now instead of
3117 traversing its own lists (those lists does not exist anymore).
3118 SilcIDList though still exists. Also, SilcXXXEntry's are
3121 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Finally made the SKE implementation compliant to the protocol
3124 specification. All mp integers are now binary encoded as
3125 opposed being HEX encoded.
3127 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3130 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3131 functions: silc_[encode/decode]_pem. Also added function
3132 silc_encode_pem_file to PEM encode with newlines ('\n') for
3135 * SILC public keys are now encoded either PEM or binary. Same
3136 option is for private keys as well. By default private keys
3137 are binary encoded and public keys PEM encoded. Silly HEX
3138 encoding were removed.
3140 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3141 function to create fingerprints.
3143 * Fixed a bug in SHA1; does not change the original data anymore.
3145 * Partly implemented INFO command on client and server side.
3146 Fixed CLEAR command. Changes to SERVER command; show current
3147 server(s) when giving command without arguments. Added
3148 VERSION command to client.
3150 * Added check to server that unregistered connections cannot
3151 execute commands (unless it is specificly allowed).
3153 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Fixed screen refresh.
3157 * Fixed channel joining bug from client. On some circumstances
3158 client tried to join to a channel it had already joined.
3160 * Added public key verification process into client's protocol.c.
3161 The client now verifies the public key from user and saves
3162 it into ~./silc/serverkeys/ directory.
3164 Added into: clientutil.[ch]: silc_client_verify_server_key.
3166 * Changed SKE protocol's silc_ske_initiator_finish function
3167 to accept callback function that verifies the received public
3168 key. Removed old silc_ske_verify_public_key function.
3170 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3173 silc_pkcs_private_key[_data]_set.
3175 * Made the password and public authentication more cleaner in
3176 server's protocol.c.
3178 * Removed historic and obsolete protocol `channel_auth' from
3179 both client and server.
3181 * Removed wrong way of sending command status messages from
3182 server to client in server's command.c. The old way violated
3183 protocol specification.
3185 Changes to silccore/silccommand.[ch]: removed
3186 silc_command_encode_status_payload -> not needed anymore,
3187 changed silc_command_encode_payload_va to accept extra
3188 argument on variable argument list. The argument type must
3189 now be provided to the function. Also, added new function:
3190 silc_command_encode_reply_payload_va which is same as
3191 normal command_encode_payload_va except command status type
3192 is provided as extra argument.
3194 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Added ~./silc directory handling. The directory includes the
3197 public and private keys for the client.
3199 Added silc_client_check_silc_dir, silc_client_create_identifier
3200 and silc_client_load_keys.
3202 * Implemented SILC protocol compliant public key. Added public
3203 and private key saving to and loading from files.
3205 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3206 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3207 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3208 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3209 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3211 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3212 silc_pkcs_load_[public/private]_key.
3214 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Added silc_server_get_route (route.[ch]) to get connection
3217 data for the fastest route for given ID.
3219 * Implemented INVITE command on client and server. The command
3220 were re-defined in the SILC Protocol Specification and the
3221 implementation now complies with the specification.
3223 * Implemented PING command on client and server.
3225 * Implemented NAMES command on client and server. The server side
3226 supports currently only normal server not router server yet.
3227 Some changes to NAMES definition in SILC protocol specification.
3229 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Implemented LEAVE command on client and server.
3233 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3234 again. This change was made to the protocol as well. Server
3235 should not violate the protocol specification anymore.
3237 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3240 was tested. SOCKS4 was not but should work anyway.
