5 * Removed the nickname from the Private Message Payload.
6 Updated the code and the protocol specs.
8 * Updated protocol specs for submitting to the IETF.
10 * Tweaked the Random Number Generator a bit. Affected file
11 lib/silccrypt/silcrng.c. Exported a new function
12 silc_rng_[global]_add_noise which can be used to add more
15 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
17 * Do not parse packets with different timeout when protocol
18 is active -> may cause problem with rekey. Affected file
21 * When server receives signoff notify it must not create
22 new channel key if the client is on any channels since the
23 sender of the signoff notify will create it.
25 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Added printing of error messages during SKE protocol from the
28 failure packet sent by server during SKE. Affected file
31 * Removed the client's failure_callback handling with timeout
32 and handle it immediately when received.
34 * The SKE library returned wrong type in SUCCESS and FAILURE
35 packets. They must be 32 bit MSB not 16 bit MSB.
37 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Ok, rewrote the logic of the re-key and now it seems to work.
40 I tested it on high traffic with frequent re-keys without
41 problems. Added hmac_receive (and renamed hmac to hmac_send)
42 in SilcClientConnection in lib/silcclient/client.h and
43 in SilcIDListData in silcd/idlist.h. Also, removed the
44 SilcPacketParserContext's cipher and hmac fields as they are
45 not needed anymore and actually caused some problems when
46 the ciphers and hmac's changed underneath the packet parser.
48 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * If re-key protocol is active then process the incoming packets
51 synchronously since we must assure that icoming packets encrypted
52 with the old key is processed before the new keys is set to
53 use. This is true other packets than for REKEY packets.
54 Affected file silcd/server.c. The same was done to client library
55 as well, affected file lib/silcclient/client.c.
57 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
59 * Fixed bug in client and server to accept the force send if
60 the packet is send from silc_[server/client]_packet_process
61 function. Otherwise the packets are never delivered, oops.
63 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Disable force sending of packets when REKEY protocol is active.
66 We must assure that no packet is sent directly when rekey is
67 performed. All packets must be sent through packet queue.
68 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
69 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
70 function is silc_[server/client]_packet_send_real to check
73 * Replaced the SIM paths from example config files to
74 /usr/local/modules. Also, make install creates now
75 /usr/local/silc/logs directory to hold all the SILC server
78 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Made the configure.in.pre work on Solaris. Patch by salo.
82 * Made all ciphers compatible with non-x86 machines. Defined
83 CBC mode macros into lib/silccrypt/ciphers_def.h.
85 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Fixed the make install.
89 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
91 * When MAC computation fails the silc_packet_decrypt returned 0
92 even though it was supposed to return -1. Fixed this. The
93 affected file is lib/silccore/silcpacket.c.
95 * Do not replace the config files in /etc/silc (in make install)
96 if they already exist. Affected file ./Makefile.am.
98 * Do not send re-key packets immediately but through packet queue.
99 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
101 * Changed silc_net_check_host_by_sock to return FALSE if the
102 IP/DNS could not be resolved. Though, it returns the IP address
103 now even if it could not resolve it (but returns also FALSE).
104 Affected file lib/silcutil/silcnet.[ch].
106 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added silc_pkcs_decode_identifier to decode the public key's
109 identifier. Affected file lib/silccrypt/silpkcs.[ch].
110 Added also silc_pkcs_free_identifier. Added also new context
111 SilcPublicKeyIdentifier.
113 * Added -S option to the silc client. It is used to dump the
114 contents of the specified public key file.
116 * Changed the PKCS api to return the public key length when
117 setting the public key.
119 * Fixed a fatal bug in the public and private key file loading.
120 Affected file lib/silccrypt/silcpkcs.c.
122 * Execute the packet parsing for client with zero (0) timeout
123 if the protocol is active. Affected file silcd/server.c.
125 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Made the key generation options to the silcd program. Added
128 -C option, equivalent to client's option.
130 * Added new [ServerKeys] config section to the server. It
131 configures the server's public and private key.
133 * Defined generic Public Key Payload into the protocol
134 specification to send specific type of public keys and
137 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
138 public key or certificate.
140 * Implemented the GETKEY command to the server and to the
141 client library and on user interface.
143 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Made preliminary `make install' work.
147 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Added SilcServerRekey context into silcd/idlist.h.
151 * Added the PFS support as defined in the specification to the
152 SKE protocol. Affected files lib/silcske/*.c.
154 * Added `ske_group' field to the SilcServerRekey context to hold
155 the number of the SKE group that is used with PFS in re-key.
156 Affected file silcd/idlist.h.
158 * Added PFS re-key support to the server. Affected file is
161 * Added silc_protocol_cancel to cancel execution of the next
162 state of the protocol. Affected file is
163 lib/silccore/silcprotocol.[ch].
165 * Added the re-key support with and without PFS to the client
166 library. Re-key is performed once in an hour, by default.
168 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
169 Added silc_client_rekey_callback and silc_client_rekey_final.
170 Affected files are lib/silcclient/protocol.[ch] and
171 lib/silcclient/client.[ch].
173 * Removed the `hmac_key' and `hmac_key_len' fields from the
174 SilcClientConnection structure; not needed. Affected file is
175 lib/silcclient/client.h.
179 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Do not ask whether user wants to use the negotiated private key
182 for private messages, just use it. Affected file is
183 silc/local_command.c.
185 * Added `send_enc_key' and `enc_key_len' fields to the
186 SilcIDListData structure since they are needed in the re-key
187 phase. Affected file is silcd/idlist.[ch].
189 * Implemented the simple re-key protocol into the server.
190 Affected files silcd/server.c and silcd/protocol.[ch]. The
191 re-key will be performed once in an hour, by default.
193 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
194 Added silc_server_rekey, silc_server_rekey_callback and
195 silc_server_rekey_final.
197 * Removed Tunneled flag from the protocol. Updated the code
198 and the specifications.
200 * Adde `pfs' field to the SilcIDListData to indicate whether
201 the PFS is to be performed in the re-key. Affected file is
204 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
207 int64 of at least the xintXX size. If void * is less that 4
208 bytes uint32 * will be used. Defined bool as boolean.
210 * Changed _ALL_ unsigned long and unsigned int to uint32,
211 unsgined short to uint16 in the source tree.
213 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
214 not handle clients that has entry->data.registered == FALSE.
215 They are not in the network anymore. Affected file is
218 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Implemented the sending of the SERVER_SIGNOFF notify in the
221 server. Affected file is silcd/server.c.
223 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
224 Added also silc_notify_payload_encode_args into the
225 lib/silccore/silcnotify.[ch].
227 * Implemented ther SERVER_SIGNOFF notify handling in the server.
228 Affected file silcd/packet_receive.c.
230 * Implemented the SERVER_SIGNOFF notify handling in the client
231 library. Affected file lib/silcclient/client_notify.c. Also,
232 implemnted the printing of the SERVER_SIGNOFF info to the
233 application. Affected file silc/client_ops.c.
235 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
236 if the deleting was successful. Affected file silcd/idlist.[ch].
238 * Added support for public key authentication in the connection
239 authentication protocol in the client library. Affected file
240 lib/silcclient/protocol.c.
242 * Changed the server's silc_idlist_get_clients_by_* interface
243 to support already allocated array so that new entries may be
244 added to pre-allocated array. Affected file silcd/idlist.[ch].
245 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
248 * All command reply functions in the server now calls the
249 pending command callback even if error occured. This way the
250 error will be delivered to the client as well. Affected files
251 silcd/command.c and silcd/command_reply.c.
253 * Fixed INFO command to return local server's info if no server
254 was provided. Affected file lib/silcclient/command.c.
256 * Removed RESTART command for good. Updated the code and the
259 * Rewrote parts of the task system. It is a bit simpler now.
260 Removed unsued task priorities. The affected files are
261 lib/silcutil/silctask.[ch].
263 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Moved the USERS printing from the library to the application.
266 Affected files lib/silcclient/command.c and silc/client_ops.c.
268 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Added channel key re-key support. The re-key is perfomed
273 only by the router and is done once in an hour. Added `rekey'
274 field to the SilcChannelEntry in the server. Affected files
275 silcd/server.c and silcd/idlist.h.
277 * Added silc_task_unregister_by_context into the file
278 lib/silcutil/silctask.[ch].
280 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Added SILC_UMODE_GONE mode to indicate when the client is not
283 present in the SILC network. Added also support to the local
284 command AWAY that will set this mode. Added support of showing
285 "xxx is gone" in WHOIS command. The USERS command shows the
288 * Fixed setting server and router operator privileges in the
289 server's UMODE command. Affected file silcd/command.c.
291 * Merged the SKE KE1 and KE2 payloads into one payload. The
292 new KE payload is equivalent to the old KE2 payload.
294 Cleaned up the SKE Start Payload parsing. It now uses the
295 simple buffer unformatting to do the parsing. A lot faster
298 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
299 to the SKE that is used to indicate whether both of the SKE
300 parties should perform authentication. By default only the
301 responder performs authentication. By setting this flag also
302 the initiator must do authentication. By default it is unset
303 since in normal SKE case, client to server connection, only
304 the responder should do authentication. When doing SKE between
305 two clients both should perform authentication. Updated the
306 code and the protocol specs.
308 * A little fix to IDENTIFY command in the server. Search the
309 client first by hash not nickname. Affected file is
312 * Fixed the silc_client_close_connection to support closing
313 the client to client connections wihtout deleting too much
314 data. Affected file lib/silcclient/client.c.
316 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
317 are received if protocol used to be active but is not anymore
318 the application would crash due to NULL pointer dereference.
319 Affected files silcd/server.c and lib/silcclient/client.c.
321 * Added `hash' field to the SilcClientConnection to include
322 the hash function negotiated in the SKE protocol.
324 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
325 to set the channel founder authentication data. A client can
326 claim the founder rights later by providing the authentication
327 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
328 This way the channel founder can regain the channel founder
329 privileges even it is left the channel. This works only on
330 local server and the client must be connected to the same
331 server to be able to regain the founder rights. Updated the
332 protocol specs accordingly.
334 Added support to the CMODE command in the client to set the
335 founder auth data. Read the README to see how to set it.
337 Added support to the CUMODE command to claim the founder
338 rights. Read the README to see how to do it.
340 Added support for the founder authentication to the Channel
341 Entry in the server. Affected file silcd/idlist.h.
343 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
344 server's CMODE command. Affected file silcd/command.c.
346 * Added the following new functions into lib/silccore/silcauth.[ch]:
347 silc_auth_get_method and silc_auth_get_data.
349 * The server now saves the remote hosts public key to the
350 SilcIDListData pointer. Affected file silcd/protocol.c.
352 * The normal server now does not remove the channel entry from
353 the cache if the founder authentication data is set. It used
354 to remove it if the founder was the last one on the channel on
355 the server and left the channel. The auth data is saved and
356 if the channel is re-joined later the old entry is used with
357 the old auth data. Affected files silcd/command_reply.c and
360 * Removed the `pkcs' field from the SilcIDListData structure
361 in the server; it is not used. Affected file silcd/idlist.h.
363 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
365 * Fixed packet processing on slow links. Partial packets were
366 never re-processed because the incoming data buffer was cleared
367 by the application. Application must not directly clear the
368 sock->inbuf, the packet processing routines handle it. Fixed
369 this in client library and in server.
371 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
373 * Fixed the WHOIS and IDENTIFY send reply function to really
374 check whether to send list or just one entry. Affected file
377 * Cleaned up the LEAVE command's channel key distribution. The
378 affected file silcd/command.c.
380 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
381 can enforce the channel mode as well. In that case the ID
382 includes the ID of the server. The code now enforces the
383 mode change if the router have different mode than the server.
385 * The notify client operation with CMODE_CHANGE notify can now
386 return NULL client_entry pointer if the CMODE was not changed
387 by client. Application must check for this.
389 * Added <Server ID> argument to INFO command to support server
390 info fetching by Server ID.
392 * Added silc_server_announce_get_channel_users to get assembled
393 packets of channel users of the specified channel. Affected
394 file silcd/server.[ch].
396 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
397 was freed underneath the ID Cache.
399 * Re-announce clients when the server received CHANNEL_CHANGE
400 notify from the router. Affected file silcd/packet_send.c.
402 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
404 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
405 crashed since it did not handle the fact that there is no cipher
406 called "3" and didn't check the error condition. Now fixed.
408 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
409 flag. It can be used to send message requests.
411 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Implemented the RESTART command in the client.
415 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
416 notice type messages. Added notice printing to the user
419 * The channel keys are not re-generated if the channel's mode
420 is PRIVKEY, ie private key on the channel exists. Affected
421 files silcd/server.c and silcd/command.c.
423 * Fixed a little bug in channel message delivery when channel
424 private keys are set in the server. Affected file is
427 * Changed the setting on channel->on_channel = TRUE from the
428 silc_client_save_channel_key to the JOIN command reply. The
429 key payload is not received if the private channel key is set.
430 Affected file lib/silcclient/command_reply.c and the
431 lib/silcclient/client_channel.c.
433 * When the CMODE_CHANGE notify is sent and the channel private
434 key mode is removed the channel key must be re-generated in
435 other cells as well. Added this support for the router in the
436 silcd/packet_receive.c.
438 * Added new local command NOTICE to send notice message on
439 channel. Affected file silc/local_command.[ch].
441 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Added new local command ME to the client. It is used to send
444 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
445 some action. Affected file silc/local_command.[ch].
447 * Changed channel_message and private_message client operations
448 to deliver the message flags to the application. Added also
449 the `flags' arguments to the silc_client_send_channel_message
450 and silc_client_send_private_message functions. Affected file
453 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Redefined the Private Message Payload to support private message
456 keys and to support the new private message flags. Updated
457 the protocol specs. Flags makes it possible to have for example
460 * Added new type SilcPrivateMessagePayload and defined an API
461 for it in the lib/silcclient/silcprivate.[ch].
463 * Tested private message private keys successfully. Tested the
464 private message key set, unset and list commands with the new
467 * Redefined the Channel Message Payload to include the channel
468 message flags (equal with private message flags) to support
469 for example CTCP style messages.
471 * Defined some of the message (for channel and private message)
472 flags. Updated the protocol specs and added the flags to the
473 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
475 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
477 * Added SilcKeyAgreementStatus type to the key agreement routines
478 to indicate the current status and error if one occured.
479 The status types are defined in the lib/silcclient/silcapi.h.
481 * Added new local command KEY that is used to set and unset private
482 keys for channels, set and unset private keys for private messages
483 with remote clients and to send key agreement requests and
484 negotiate the key agreement protocol with remote client. The
485 key agreement is supported only to negotiate private message keys,
486 it currently cannot be used to negotiate private keys for channels,
487 as it is not convenient for that purpose.
489 * Fixed a minor pending callback setting bug in the function
490 silc_client_get_client_by_id_resolve, now the function works.
491 Affected file lib/silcclient/idlist.c.
493 * Added function silc_net_get_local_port to get local bound
494 port by socket. Added to lib/silcutil/silcnet.[ch].
496 * Added `sockets' and `sockets_count' fields to the SilcClient
497 object. They hold the sockets of the listenning sockets in
498 the client. Listenning sockets may be for example the key
499 agreement server. Affected file lib/silcclient/client.[ch].
500 Added functions the silc_client_add_socket and the
501 silc_client_del_socket. They are exported to the application
504 * Added ~./silc/clientkeys to support other client's public keys.
506 * Renamed verify_server_key client operation to verify_public_key
507 and added one argument to indicate the type of the connection
508 (server, client etc.).
510 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Added silc_server_connection_auth_request to handle the
513 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
514 silcd/packet_receive.[ch].
516 * Added silc_server_send_connection_auth_request into the
517 silcd/packet_send.c to send the connection auth request packet.
519 * Cleaned up the silcd/protocol.c a bit and fixed some memory
522 * Fixed the public key authentication in responder side in the
523 server. The `auth_data' pointer includes the SilcPublicKey
524 not the path to the public key. Affected file silcd/protocol.c.
526 * Implemented the public key authentication in the initiator side
527 in the server. Affected file silcd/protocol.c.
529 * Removed the [RedirectClient] config section from the server
530 configuration. Is not needed and I don't want to implement it.
532 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
534 * Cleaned up the CMODE command in the server. It now works
535 correctly and supports all the modes defined in the protocol.
536 Affected file is silcd/command.c.
538 * Added `hmac_name' field to the SilcChannelEntry in the server
539 to hold the default HMAC of the channel. It can be set when
540 creating the channel (with JOIN command). Affected files
543 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
544 type to indicate the change of the current cipher and hmac
545 on the channel. Client can safely ignore the <cipher> argument
546 (if it chooses to do so) since the CHANNEL_KEY packet will
547 force the channel key change anyway. The <hmac> argument is
548 important since the client is responsible of setting the new
549 HMAC and the hmac key into use.
551 * Fixed the CMODE command in the client library as well.
553 * Tested CMODE command in router environment successfully.
555 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
557 * Show the version of the remote client (or server) when connecting
558 to the server. It is logged to the log file. Affected file
561 * Fixed the KILLED notify handling in the client library. The
562 client must be removed from all channels when receiving the
565 Also, do not remove the client entry when giving the KILL
566 command but when the KILLED notify is received.
568 * Removed silc_idlist_find_client_by_nickname from the server.
569 Not needed anymore. Affected files silcd/idlist.[ch].
571 * Implemented the CHANNEL_CHANGE notify type handling to the
572 server. Affected file silcd/server.c.
576 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Added silc_server_send_notify_invite to send the INVITE
579 notify between routers.
581 * Implemented the INVITE command correctly to the server.
583 * Implemented the INVITE notify type handling in the server.
585 * Implemented the INVITE command to the client library and on the
588 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Added function silc_server_get_client_resolve to find the
591 client entry by ID from all ID lists and then resolve it
592 (using WHOIS) if it cannot be found. Affected file is
595 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Implemented the BAN command to the client library.
599 * The JOIN command in the server now checks the invite list
602 * Changed the silc_command_reply_payload_encode_va and the
603 silc_command_payload_encode_va to support that if argument is
604 NULL it ignores and checks the next argument. Affected file
605 lib/silccore/silccommand.c.
607 * Added silc_server_send_notify_ban to send the BAN notify
608 type between routers.
610 * Chaned the silc_notify_payload_encode to support that if
611 argument is NULL it ignores and checks the next argument.
612 Affected file lib/silccore/silcnotify.c.
614 * Tested ban lists in router environment successfully.
616 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Implemented BAN command to the server, in silcd/command.[ch].
620 * Removed the BAN and INVITE_LIST modes from the CMODE command
623 * Added function silc_string_match to regex match two strings.
624 Affected files lib/silcutil/silcutil.[ch].
626 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Redefined parts of the SilcChannelEntry in the server to support
629 the new ban and invite lists.
631 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Redefined the INVITE command. The same command can be used to
634 invite individuals to the channel but also to manage the invite
635 list of the channel (to add to and remove from the invite list).
636 Updated the protocol specs.
638 * Added new command SILC_COMMAND_BAN that can be used to manage
639 the ban list of the channel. Updated the protocol specs.
641 * Removed the channel modes: the SILC_CMODE_BAN and the
642 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
643 in the CMODE command. The equivalent features are now available
644 using INVITE and BAN commands. Updated the protocol specs.
646 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
647 in the network about change in the current ban list. The notify
648 type is not used by the client.
650 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
651 support the invite lists.
653 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Added new function silc_string_regexify that converts string
656 including wildcard characters into regex string that can
657 be used by the GNU regex library. Added into the file
658 lib/silcutil/silcutil.[ch].
660 Added silc_string_regex_combine to combine to regex strings
661 into one so that they can be used as one regex string by
662 the GNU regex library. Added into the file
663 lib/silcutil/silcutil.[ch].
665 Added silc_string_regex_match to match two strings. It returns
666 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
668 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Imported GNU regex to the soruce tree into lib/contrib.
671 Fixed some compiler warning from the regex.c.
673 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * Fixed MOTD command in the server to work in router environment.
677 * Fixed the MOTD command in the client library to support
678 the server argument in the command.
680 * Added `nickname_len' argument to the silc_idlist_add_client
681 in the server, as the `nickname' argument may be binary data
684 * Added silc_idlist_get_channels to return all channels from
687 * Implemented LIST command to the server. Affected file is
690 * Implemented the LIST command to the client library and on the
693 * Added [<user count>] argument to the LIST command reply.
694 With private channels the user count is not shown.
696 * Updated TODO and README.
698 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * The client entry's data.registered must be TRUE even with
701 global client entry on global client list. The data.registered
702 is used to check whether the client is anymore in the network,
703 for example with WHOWAS command so it must be valid.
705 * Fixed the WHOWAS command in the server. It now actually works
706 in router environment. Added function into silcd/command_reply.c
707 silc_server_command_reply_whowas_save.
709 * Added silc_idlist_purge function to the silcd/idlist.c
710 to periodically purge the ID Cache.
712 * Fixed INFO command in the server. It works now in router
713 environment. Added <server name> argument to the INFO command
714 reply. Updated the protocol specs.
716 * Fixed minor bug in silc_idcache_purge to not purge if the
717 expire value is zero.
719 * Fixed various bugs in WHOIS and IDENTIFY command handling as
720 they were buggy because of the WHOWAS information.
722 * Fixed local command MSG to handle the async resolving of
723 the remote client properly. It used to fail the first MSG.
724 Affected file silc/local_command.c.
726 * Added `data_len' field to SilcIDCache context.
728 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Update TODO. Todo in commands in the server.
732 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
735 used by routers as broadcast packet to inform other routers
736 about the changed user mode.
738 Implemented the notify handling in the server. Affected file is
739 silcd/packet_receive.c. Added the function
740 silc_server_send_notify_umode to the silcd/packet_send.[ch].
742 * Added new generic Channel Payload and deprecated the New Channel
743 Payload. The New Channel Payload is now the generic Channel
746 * Added new argument `mode' to the silc_server_send_new_channel
747 as it is required in the Channel Payload now.
749 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
750 and created a new and real SilChannelPayload to represent the
751 new generic Channel Payload. Implemented the encode/decode
752 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
754 * Added silc_server_get_client_channel_list to return the list
755 of channels the client has joined for WHOIS command reply.
756 Affected file silcd/server.[ch].
758 * Implemented the channel list sending in the WHOIS command reply
759 in server and in the client.
761 Implemented the channel list displaying on the user interface
762 as well. Affected file silc/client_ops.c.
764 * Added silc_channel_payload_parse_list to parse list of Channel
765 Payloads. It returns SilcDList list of SilcChannelPayloads.
766 Client for example can use this function to parse the list of
767 channels it receives in the WHOIS command reply. The caller
768 must free the list by calling silc_channel_payload_list_free.
769 Affected files lib/silccore/silcchannel.[ch].
771 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
773 * Added one new argument <user mode> to the WHOIS command reply
774 to return the mode of the user in SILC. Updated the protocol
777 Implemented it to the server and client.
779 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Fixed the mode printing on the user interface on joining.
782 Affected file silc/client_ops.c.
784 * Implemented the UMODE command and user modes in general to the
785 client library and to the user interface.
787 * Implemented the UMODE command to the server.
789 * The server now sends UNKNOWN_COMMAND error status if client sends
790 unknown command. Affected file silcd/command.c.
792 * All server commands now handle the command identifier the right
793 way when sending the command reply to the client. The client can
794 use to identify the command replies with the identifier.
796 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Added silc_server_get_client_route to resolve the route to
799 the client indicated by the client ID. Affected file is
802 * Added silc_server_relay_packet as general function to relay
803 packet to arbitrary destination. This deprecates functions
804 like _send_private_message_key, _relay_notify etc. Affected
805 file is silcd/packet_send.[ch].
807 Removed silc_server_send_key_agreement,
808 silc_server_send_private_message_key and
809 silc_server_packet_relay_notify functions from the file
810 silcd/packet_send.[ch].
814 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
815 server. Affected file silcd/packet_receive.[ch].
817 * Implemented the KILL command to the client. Implemented the
818 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
819 Affected files lib/silcclient/command[_reply].c and
820 lib/silcclient/client_notify.c. Implemented the KILL notify
821 printing in the user inteface.
823 * Fixed a lot silc_parse_nick memory leaks from the client
824 library in the file lib/silcclient/command.c.
826 * Changed the silc_server_send_notify_on_channels's `sender'
827 argument from SilcSocketConnection to SilcClientEntry to
828 check the sender as entry and not as connection object and not
829 to send to the client provided as argument. The affected file
830 is silcd/packet_send.[ch].
832 * The notify packets that are destined directly to the client used
833 to not to be processed by the server. Now changed that and the
834 server processes all notify packets. After relaying the packet
835 to the client the notify packet is processed in the server.
837 * The silc_server_free_client_data now checks whether there is
838 pending outgoing traffic for the client and purges the data to
839 the network before removing the client entry.
841 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
844 an client is killed from the SILC Network. Updated the protocol
847 Added new function silc_server_send_notify_killed to the
848 silcd/packet_send.[ch].
850 * Added function silc_server_packet_relay_notify to relay notify
851 packets that are destined directly to a client. In this case
852 the server does not process the notify packets but merely relays
853 it to the client. Affected file silcd/packet_send.[ch].
855 Added also silc_server_packet_process_relay_notify to check
856 whereto relay the notify. Affected file is
857 silcd/packet_receive.[ch].
859 * Implemented the KILL command to the server.
863 * Added the backup schema desgined last fall to the protocol
864 specs for everyone to see. The specification is in the
865 *-spec-xx.txt draft and the packet type definitions for the
866 backup routers is in *-pp-xx.txt draft. Thusly, added also
867 new packet type SILC_PACKET_CELL_ROUTERS.
869 * A big security problem in the implementation discovered. The
870 signoff of an client did not cause new channel key generation
871 which it of course should've done. The channel keys must be
872 always re-generated when client leaves (or signoffs) the channel.
873 The silc_server_remove_from_channels funtion now handles
874 the channel key re-generation.
876 * Added `sender' argument to the silc_server_send_notify_on_channels
877 to not to send the client provided as argument. Affected file
878 silcd/packet_send.[ch].
880 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Implemented OPER and SILCOPER commands into the server and
885 * Added silc_auth_verify and silc_auth_verify_data to verify
886 the authentication directly from the authentication payload.
887 It supports verifying both passphrase and public key based
888 authentication. Affected file lib/silccore/silcauth.[ch].
890 * Added `hash' field to the SilcIDListData structure. It is the
891 hash negotiated in the SKE protocol. Affected file is
894 * Slight redesigning of the SilcAuthPayload handling routines.
895 Do not send SilcPKCS but SilcPublicKey as argument.
897 * Implemented the public key authentication support to the
898 serverconfig. The public key is loaded from the provided path
899 and saved as authentication data to void * pointer. Thus,
900 changed the unsigned char *auth_data to void *auth_data;
902 * Fixed SHUTDOWN command to send the reply before the server
903 is shutdown. :) Affected file silcd/command.c.
905 * Fixed fatal bug in CONNECT command. The hostname was invalid
906 memory and server crashed. Affected file silcd/command.c.
908 * Fixed fatal bug in CLOSE command. The server_entry became
909 invalid but was referenced later in the command. Affected file
912 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Fixed fatal bug in failure packet handling. Server ignored
915 the failure and thus crashed when it came.
919 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
922 that the command may be executed only once in (about) 2 seconds.
923 The old SILC_CF_LAG flag is same but allows command bursts up
924 to five before limiting.
926 Added the support for CF_LAG and CF_LAG_STRICT flags to the
927 server code. Various commands now includes the CF_LAG_STRICT
928 flag to disallow any kind of miss-use of the command.
930 * Fixed the silc_buffer_unformat to not to allocate any data
931 if the length of the data is zero. It used to allocate the
932 length + 1. Affected file lib/silcutil/silcbuffmt.c.
934 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Changed the format of AdminConnection configuration section
937 in the server. Added username of the admin to the format.
938 Affected files silcd/serverconfig.[ch].
940 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
941 to return admin configuration data by host, username and/or
944 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Implemented WHOWAS command to the server. Added the functions:
948 silc_server_command_whowas_parse,
949 silc_server_command_whowas_send_reply,
950 silc_server_command_whowas_from_client and
951 silc_server_command_whowas_from_server
953 * Added <Client ID> argument to the WHOWAS command reply. Updated
954 the protocol specs accordingly.
956 * Implemented WHOWAS command and command_reply to the client
959 Implemented the WHOWAS printing on the user interface.
961 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Added new argument to the WHOWAS command reply, the real name.
964 It is an optional argument. Updated the protocol specs.
966 * Added SilcIDCacheDestructor callback that is registered when
967 the SilcIDCache is allocated. The callback is called when
968 an cache entry in the ID Cache expires, or is purged from the
969 cache. Added into lib/silccore/idcache.[ch].
971 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
972 to destruct the client entries when the cache entry expires.
973 Other ID Cache's in server and in the client library ignores
976 * If the ID Cache entry's `expire' field is zero then the entry
977 never expires. Added boolean `expire' argument to the
978 silc_idcache_add function in the lib/silccore/idcache.[ch].
979 If it is TRUE the default expiry value is used.
981 * Added silc_server_free_client_data_timeout that is registered
982 when client disconnects. By default for 5 minutes we preserve
983 the client entry for history - for WHOWAS command.
985 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added support to the server to enforce that commands are not
988 executed more than once in 2 seconds. If server receives
989 commands from client more frequently, timeout is registered
990 to process the commands. Affected file silcd/command.c.
991 Added new function silc_server_command_process_timeout.
993 * Changed NICK_NOTIFY handling in client library to check that
994 if the client's nickname was changed, so there is no need to
995 resolve anything from the server.
997 * Removed error printing from the WHOIS and IDENTIFY commands.
998 If error occurs then it is ignored silently in the client library.
999 The application, however, may map the received error to
1000 human readable error string. The application currently maps
1001 the NO_SUCH_NICKNAME error to string.
1003 * Made the command status message public to the application. Moved
1004 them from lib/silcclient/command_reply.c to
1005 lib/silcclient/command_reply.h. The application can map the
1006 received command status to the string with the
1007 silc_client_command_status_message function.
1009 * Added check to the server to check that client's ID is same
1010 as the Source ID in the packet the client sent. They must
1013 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Added dist-bzip hook to the Makefile.am to make bzip2
1016 compressed distributions.
1018 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Server now enforces the maximum length for the nickname and
1021 the channel as protocol specification dictates. 128 bytes for
1022 nickname and 256 bytes for channel name.
1024 * Moved the WHOIS printing to the application. The client libary
1025 does not print out the WHOIS information anymore, the application
1026 must do it. Renamed silc_client_command_reply_whois_print to
1027 the silc_client_command_reply_whois_save.
1029 The client's idle time is also sent to the application now, and
1030 the idle is shown on screen.
1032 * Added silc_client_command_reply_identify_save to save the
1033 received IDENTIFY entries.
1035 * Do not check for channel private keys in message sending and
1036 reception if the channel does not have the PRIVKEY mode set.
1037 Affected file lib/silclient/client_channel.c.
1039 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1042 just surfaced after chaning the JOIN procedure.
1044 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Added silc_client_get_clients_by_list to get client entries
1047 from Client ID list, that is returned for example by JOIN
1048 and USERS command replies. The application should use this
1049 function for example when JOIN command reply is received to
1050 resolve the clients already on the channel (library does not
1051 do that anymore as USERS command reply is not used in the JOIN
1052 procedure anymore). Affected files lib/silcclient/silcapi.h and
1053 lib/silcclient/idlist.c.
1055 * JOIN command reply and USERS command reply returns now SilcBuffer
1056 pointers instead of unsigned char pointers when returning
1057 the client list and mode list.
1059 * Added <Client ID> argument to the JOIN command reply, mainly
1060 for the server to identify for which client the command was
1061 originally sent. Updated protocol specs accordingly.
1063 * Added SilcDlist private_key pointer to the SilcChannelEntry
1064 in the client to support the channel private keys. Affected
1065 file is lib/silcclient/idlist.h.
1067 * Added SilcChannelPrivateKey argument to the function
1068 silc_client_send_channel_message so that application can choose
1069 to use specific private ke if it wants to. If it is not provided,
1070 the normal channel key is used, unless private keys are set.
1071 In this case the first (key that was added first) is used
1072 as the encryption key.
1074 * Implemented the support for channel private key handling.
1075 Implemented the following functions:
1077 silc_client_add_channel_private_key,
1078 silc_client_del_channel_private_keys,
1079 silc_client_del_channel_private_key,
1080 silc_client_list_channel_private_keys and
1081 silc_client_free_channel_private_keys
1083 Affected file lib/silcclient/client_channel.c.
1085 * Added the support for the private keys in the channel message
1086 sending and encryption and in the message reception and
1087 decryption. Affected funtions are
1088 silc_client_send_channel_message and silc_client_channel_message.
1090 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1092 * Added SKE's key verify callback to the client library's
1093 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1095 * Removed the statement that server (or router) must send USERS
1096 command reply when joining to the channel so that the client
1097 knows who are on the channel. Instead, the client list and
1098 client's mode list is now sent in the JOIN command reply to the
1099 client who joined channel. This is better solution.
1101 * Added function silc_server_get_users_on_channel and function
1102 silc_server_save_users_on_channel to the silcd/server.[ch].
1104 * Removed function silc_server_command_send_users from the
1107 * Do not show topic on the client library anymore. The topic is
1108 sent in the command reply notify to the application and the
1109 application must show the topic now.
1111 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Added client searching by nickname hash into the IDENTIFY and
1114 WHOIS commands in the server as they were clearly missing from
1115 them. Affected file is silcd/command.c.
1117 * Fixed a bug in private message receiving in the client library.
1118 The remote ID was freed and it wasn't supposed, now it is
1121 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Minor fix to the channel payload; allocate the data area, as it
1124 needs to be of specific length.
1126 * If the key agreement port is zero then the operating
1127 system will define the bound port. Affected files are
1128 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1130 * Added new function silc_channel_payload_decrypt into the file
1131 lib/silccore/silcchannel.[ch].
1133 * Moved the channel message etc, check from silc_packet_decrypt
1134 to applications. The library calls now a generic
1135 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1136 when the packet is either normal or special. This was done to
1137 allow more wide range of checking that was not allowed when
1138 the code was in library. Now applications can do virtually any
1139 checks to the packet and return to the library the decision how
1140 the packet should be processed. Affected files are
1141 lib/silccore/silcpacket.[ch].
1143 Added silc_server_packet_decrypt_check to the server and
1144 silc_client_packet_decrypt_check to the client library.
1146 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1147 to send with specified source and destination information.
1149 * Channel message delivery between routers was broken after the
1150 channel key distribution was fixed earlier. The channel key
1151 was used be to distributed to other routers as well which is not
1152 allowed by the protocol. Now this is fixed and channel keys
1153 really are cell specific and the channel message delivery between
1154 routers comply with the protocol specification.
1156 * Fixed various commands in server to check also the global list
1157 for the channel entry and not just the local list. The affected
1158 file silcd/command.c.
1160 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Added assert()s to buffer formatting and unformatting routines
1163 to assert (if --enable-debug) when error occurs. Affected
1164 file: lib/silcutil/silcbuffmt.c.
1166 * Changed to auto-reconnect to check whether the remote host is
1167 router and register the re-connect timeout if it is. It used
1168 to check that whether we are normal server, but router must do
1169 auto-reconnect with another router as well. Affected file
1172 * Removed the [<key len>] option from CMODE command as the cipher
1173 name decides the key length, nowadays. See the defined ciphers
1174 from the protocol specification.
1176 * Added [<hmac>] option to the CMODE command to define the HMAC
1177 for the channel. Added SILC_CMODE_HMAC channel mode.
1179 * Added [<hmac>] option for the JOIN command so that user can
1180 select which HMAC is used to compute the MACs of the channel
1183 * Added Hmac field to the Channel Message Payload. The integrity
1184 of plaintext channel messages are now protected by computing
1185 MAC of the message and attaching the MAC to the payload. The
1186 MAC is encrypted. Now, it is clear that this causes some
1187 overhead to the size of the packet but rationale for this is that
1188 now the receiver can verify whether the channel message decrypted
1189 correctly and also when private keys are set for the channel the
1190 receiver can decrypt the packet with several keys and check from
1191 the MAC which key decrypted the message correctly.
1193 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1194 lib/silccrypt/silccipher.[ch].
1196 * Added silc_hash_len to return the digest length into the
1197 lib/silcrypt/silchash.[ch].
1199 * Rewrote parts of Silc Channel Payload interface in the
1200 lib/silccore/silcchannel.[ch]. The encode function now also
1201 encrypts the packet and parse function decrypts it.
1203 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Fixed a minor formatting bug in the SKE's key material processing.
1206 It actually might have processed the keys wrong way resulting
1209 * Redefined the mandatory HMAC algorithms and added new algorithms.
1210 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1211 and hmac-md5 truncated to 96 bits. The mandatory is now
1212 hmac-sha1-96. Rest are optional (including the one that used
1213 to be mandatory). Rationale for this is that the truncated HMAC
1214 length is sufficient from security point of view and can actually
1215 make the attack against the HMAC harder. Also, the truncated
1216 HMAC causes less overhead to the packets. See the RFC2104 for
1219 * Added new [hmac] configuration section. The SKE used to use
1220 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1221 is of course wrong. The official names that must be proposed in
1222 the SKE are the ones defined in the protocol specification
1223 (hmac-sha1-96 for example). The user can configure any hmac
1224 using any hash function configured in the [hash] section. At
1225 least, the mandatory must be configured.
1227 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1229 * Added HMAC list to the SKE proposal list. It has now both
1230 hash algorithm list and HMAC list. This makes the protocol
1231 incompatible with previous versions. The SKE now seems to work
1232 the way it is supposed to work, for the first time actually.
1234 * Defined plain Hash algorithms to the protocol specification.
1237 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Implemented support for key agreement packets into the server.
1240 Added functions silc_server_key_agreement and
1241 silc_server_send_key_agreement. Other than these functions,
1242 server has nothing to do with this packet.
1244 * Added support for private message key packets into the server.
1245 Added functions silc_server_private_message_key and
1246 silc_server_send_private_message_key.
1250 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1251 called in the protocol's final callback instead in the END
1252 protocol state. This makes a little more sense and in the same
1253 time in client we can use the same protocol routines for normal
1254 key exchange and to key agreement packet handling as well.
1256 * Added to both client's and server's KE protocol context the
1257 SilcSKEKeyMaterial pointer to save the key material. We will
1258 bring the key material to the protocol's final callback by doing
1259 this. The final callback must free the key material.
1261 * Added SKE's packet_send callback into client's KE protocol
1262 context so that the caller can choose what packet sending function
1263 is used. This way we can use different packet sending when
1264 doing normal SKE when doing key agreement packet handling (in
1265 the key agreement packet handling we do not want to encrypt
1268 * Implemented the responder side of the key agreement routines
1269 in the client. The client can now bind to specified port and
1270 accept incoming key negotiation. The key material is passed
1271 to the application after the protocol is over.
1273 * Implemented the processing of incoming Key Agreement packet
1274 in the client. Added function silc_client_key_agreement to
1277 * Implemented the intiator side of the key agreement routines
1278 in the client. The client can now initiate key agreement with
1279 another remote client. The key material is passed to the
1280 application after the protocol is over.
1282 * Created client_keyagr.c to include all the key agreement
1285 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1286 SILC_TASK_CALLBACK except that it is not static.
1288 * Created client_notify.c and moved the Notify packet handling
1289 from the client.[ch] into that file.
1291 * Created client_prvmsg.c and moved all private message and
1292 private message key routines from the client.[ch] into that file.
1294 * Create client_channel.c and moved all channel message and
1295 channel private key routines from the client.[ch] into that file.
1297 * Changed silc_client_get_client_by_id_resolve to resolve with
1298 WHOIS command instead of IDENTIFY command, in the file
1299 lib/silclient/idlist.c.
1301 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1303 * Implemented the SKE's responder side to the Client library.
1305 * When FAILURE is received to the protocol do not trust it
1306 blindly. Register a timeout to wait whether the remote closes
1307 the connection as it should do it, only after that process the
1308 actual failure. This was changed to both client and server.
1310 * Added client_internal.h to include some of the structures
1311 there instead of client.h in lib/silcclient/.
1313 * Added function silc_task_unregister_by_callback to unregister
1314 timeouts by the callback function.
1316 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Some "Incomplete WHOIS info" errors has been appearing on the
1319 log files. Took away the entry->userinfo check from WHOIS
1320 reply sending. The entry->userinfo is now " " if client did not
1321 provide one. I thought this was fixed earlier but something
1322 is wrong still. Let's see if the error still appears.
1324 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Fixed a minor bug in the login when the channel key is
1327 re-generated in the server. It used to generate the key in
1328 wrong order and thus caused problems in the channel traffic.
1330 * Fixed a minor bug in channel key distsribution after
1331 KICK command. The key was not sent to the router even though
1334 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Added silc_ske_process_key_material_data as generic routine
1337 to process any key material as the SILC protocol dictates. The
1338 function is used by the actual SKE library but can be used by
1339 applications as well. This relates to the private message keys
1340 and the channel private keys since they must be processed the
1341 same way the normal SILC session keys. The protocol dictates
1342 this. Affected files: lib/silcske/silcske.[ch].
1344 Added also silc_ske_free_key_material to free the
1345 SilcSKEKeyMaterial structure.
1347 * Defined silc_cipher_set_key function to set the key for
1348 cipher without using the object's method function. The affected
1349 files: lib/silccrypt/silccipher.[ch].
1351 * Implemented silc silc_client_add_private_message_key,
1352 silc_client_add_private_message_key_ske,
1353 silc_client_del_private_message_key,
1354 silc_client_list_private_message_keys and
1355 silc_client_free_private_message_keys functions in the
1358 Added functions silc_client_send_private_message_key to send
1359 the Private Message Key payload and silc_client_private_message_key
1360 to handle incoming Private Message Key payload.
1362 * Added Cipher field to the Private Message Key payload to set
1363 the cipher to be used. If ignored, the default cipher defined
1364 in the SILC protocol (aes-256-cbc) is used.
1366 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Removed lib/silcclient/ops.h file.
1370 Redefined parts of the SILC Client Library API. Created new
1371 file silcapi.h that deprecates the ops.h file and defines the
1372 published Client Library API. Defined also private message key
1373 API and channel private key API into the file.
1375 This is the file that the application must include from the
1376 SILC Client Library. Other files need not be included by
1377 the application anymore.
1379 * Added new key_agreement client operation callback and also
1380 defined the Key Agreement library API for the application.
1382 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1385 is used by clients to request key negotiation between another
1386 client in the SILC network. If the negotiation is started it
1387 is performed using the SKE protocol. The result of the
1388 negotiation, the secret key material, can be used for example
1389 as private message key.
1391 Implemented the Key Agreement payload into the files
1392 lib/silccore/silauth.[ch].
1394 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * Redefined ciphers for the SILC protocol. Added some new ciphers
1397 and defined the key lengths for the algorithms. Changed the
1398 code accordingly. The default key length is now 256 bits.
1400 * Fixed SKE key distribution function silc_ske_process_key_material
1401 when the key length is more than 128 bits. The default key
1402 length in SILC is now 256 bits.
1404 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1405 to indicate unsupported algorithm.
1407 * Renamed rijndael.c to aes.c and all functions as well.
1409 * Fixed a long standing channel key setting bug in client library.
1410 Weird that it has never surfaced before.
1412 * Fixed bug in channel deletion. If the entire channel is removed
1413 then it must also delete the references of the channel entry
1414 from the client's channel list as the client's channel entry and
1415 the channel's client entry share same memory.
1417 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Implemented CONNECT and SHUTDOWN commands in the client.
1421 * Implemented CLOSE command to the client.
1423 * Added the function silc_idlist_find_server_by_name into the
1424 files silcd/idlist.[ch].
1426 Added the function silc_idlist_find_server_by_conn into the
1427 files silcd/idlist.[ch].
1429 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * DIE command was renamed to SHUTDOWN. Updated the both code
1434 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1435 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1437 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1440 * Added function silc_server_create_connection function to create
1441 connection to remote router. My server implementation actually
1442 does not allow router to connect to normal server (it expects
1443 that normal server always initiates the connection to the router)
1444 so the CONNECT command is only good for connecting to another
1447 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1450 or some other client was kicked from the channel.
1452 Implemented the handling of the notify type to both client
1455 Implemented silc_server_send_notify_kicked to send the KICKED
1456 notify. It is used to send it to the server's primary router.
1458 * Implemented the KICK command into server and client.
1460 * Added `query' argument to the silc_idlist_get_client function
1461 to indicate whether to query the client from server or not if
1464 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1465 to indicate that the client is not channel founder.
1469 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Removed the rng context from SilcPacketContext structure and
1472 changed that the packet routine uses the Global RNG API.
1474 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Added support for quit message that client can "leave" on the
1477 channel when it quits the SILC. It is ditributed inside the
1478 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1480 Added silc_server_free_client_data that will take the
1481 signoff message as argument.
1483 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1485 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Updated parts of the protocol specification to keep it up
1490 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1493 payloads in one packet.
1495 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1496 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1497 use now the new List flag.
1499 * Also deprecated the following packet types: REPLACE_ID,
1500 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1502 * Added list support for Notify packet in server.
1504 * Added silc_server_send_notify_channel_change to send the
1505 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1506 the silc_server_send_replace_id.
1508 * Added silc_server_send_notify_nick_change to send the
1509 NICK_CHANGE notify type. Deprecates the function
1510 silc_server_send_replace_id.
1512 * Added silc_server_send_notify_join to send the JOIN notify type.
1513 Deprecates the function silc_server_send_new_channel_user.
1515 * Added silc_server_send_notify_leave to send LEAVE notify type.
1516 Deprecates the function silc_server_send_remove_channel_user.
1518 * Added silc_server_send_notify_cmode and
1519 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1520 types. Deprecates the silc_server_send_set_mode function.
1522 * Added SERVER_SIGNOFF notify type to indicate that server has
1523 quit. This means that all clients on the channel from that
1524 server will drop. This can be also used when netsplit happens.
1526 Deprecated REMOVE_ID packet type since it is not needed anymore
1529 Added silc_server_send_notify_server_signoff to send the
1530 SERVER_SIGNOFF notify type. Deprecates the function
1531 silc_server_send_remove_id.
1533 Added also silc_server_send_notify_signoff to send the
1534 SIGNOFF notify type.
1536 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1537 SILC protocol from this day on. Changed the protocol
1538 specification as well.
1540 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1541 notify type. It is used between routers to notify about
1542 topic changes on a channel.
1544 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1547 * Partly updated the protocol specification to comply with the
1548 changes now made. It is still though a bit outdated.
1550 * The JOIN notify type now takes one extra argument <Channel ID>.
1551 The packet used to be destined to the channel but now the
1552 JOIN type may be sent as list thus it is impossible to
1553 destine it to any specific channel. By adding this argument
1554 it is again possible.
1556 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Added CREDITS file. The CHANGES and CREDITS file will appear
1559 in the distribution as well.
1561 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1564 types in the server's silcd/packet_receive.c.
1566 * Implemented CMODE and CUMODE to work in router environment.
1568 * Fixed minor encoding and decoding buglet from the
1569 lib/silccore/silcmode.c.
1571 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1574 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1576 * Changed all SilcConfigServer* and silc_config_server* to
1577 SilcServerConfig* and silc_server_config*, respectively.
1580 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Associated the ID (client or server ID) to the Authentication
1583 Payload to avoid any possibility of forging. Updated the
1584 protocol specification and the code accordingly.
1586 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * The RSA key length is now save to the RsaKey context in the
1589 key generation process in lib/silccrypt/rsa.c. The key length
1590 is now used to figure out the maximum size of the block allowed
1591 to be encrypted/signed.
1593 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1594 is equivalent to the silc_mp_mp2bin but does not allocate any
1597 * Changed silc_mp_mp2bin API to take length argument. If it is
1598 non-zero then the buffer is allocated that large. If zero, then
1599 the size is approximated using silc_mp_sizeinbase, which however
1602 * Created Global RNG API which is global RNG that application can
1603 initialize. After initializing, any routine anywhere in the
1604 code (including library) can use RNG without allocating a new
1605 RNG object. This was done to allow this sort of use of the
1606 RNG in code that has no chance to allocate RNG object. All
1607 applications currently allocate this and many routines in the
1608 library use this. Affected file lib/silccrypt/silcrng.[ch].
1610 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1611 it to use the Global RNG API.
1613 * Defined Authentication Payload into protocol specification that
1614 is used during SILC session to authenticate entities. It is
1615 used for example by client to authenticate itself to the server
1616 to obtain server operator privileges.
1618 Implemented this payload into the lib/silccore/silcauth.[ch].
1619 Implemented also routines for public key based authentication
1620 as the new protocol specification dictates.
1622 Moved definitions of different authentication methods from
1623 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1625 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1626 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1627 silc_pkcs_verify_with_hash functions into the file
1628 lib/silccrypt/silcpkcs.[ch].
1630 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * The client entry's userinfo pointer must be always valid.
1633 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1634 will fail since it requires the userinfo. Now, the userinfo
1635 is allocated as "" if actual userinfo does not exist. Actually,
1636 it must exist and it is totally Ok to drop client connections
1637 that does not announce the userinfo. However, we will make
1638 this workaround for now.
1640 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1641 to return the remote port by socket.
1643 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1646 SILC_SERVER_PENDING_EXEC and added an new macro
1647 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1648 data or when error occurs while processing the pending command.
1650 Added new argument `destructor' into silc_server_command_pending
1651 and to the SilcServerCommandPending object. This destructor is
1652 now called after calling the pending callback or if error occurs
1653 immediately. If error occurs the actual pending callback won't
1654 be called at all - only the destructor. The destructor may be
1655 NULL if destructor is not needed.
1657 All this applies for client library code as well. Similar
1658 changes were made there as well for the pending commands.
1660 In the client, the application must now allocate the
1661 SilcClientCommandContext with the silc_client_command_alloc
1664 * Added reference counter to the SilcServerCommandContext. Added
1665 function silc_server_command_alloc and silc_server_command_dup
1668 Same type of functions added to the client library for the same
1671 * Removed the cmd_ident from IDListData away since it is now
1672 global for all connections. It is the command identifier used
1673 in command sending and with pending commands. The affected file
1676 * Added reference counter to the SilcSocketConnection objecet to
1677 indicate the usage count of the object. The object won't be
1678 freed untill the reference counter hits zero. Currently only
1679 server uses this, and client ignores it. The client must be
1680 set to use this too later. The affected files are
1681 lib/silccore/silcsockconn.[ch]. Added also the function
1682 silc_socket_dup to increase the reference counter.
1684 This was mainly added because it is possible that the socket
1685 is removed underneath of pending command or other async
1686 operation. Now it won't be free'd and proper DISCONNECTING
1687 flags, etc. can be set to avoid sending data to connection that
1688 is not valid anymore.
1690 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1691 the connection. After that it sets SILC_SET_DISCONNECTED.
1692 It is, however, possible that the socket data is not still freed.
1693 The silc_server_packet_process now checks that data is not
1694 read or written to connection that is DISCONNECTED. The socket
1695 get's freed when the reference counter hits zero.
1697 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Changed the client operation API: channel_message operation's
1700 `sender' is now the client entry of the sender, not the nickname
1701 and the `channel' is the channel entry, not the channel name.
1703 In the private_message operation the `sender' is now also the
1704 client entry of the sender not the nickname.
1706 Affected file is lib/silcclient/ops.h and all applications
1707 using the client operations.
1709 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Moved the calling of ops->connect() from connect_to_server_final
1712 into receive_new_id functin since that is the point when the
1713 client is actually allowed to send traffic to network. The
1714 affected file is lib/silcclient/client.c.
1716 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1719 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1720 (if needs broadcasting) instead of broadcasting the packets one
1721 by one which would make a burst in the network traffic.
1723 * Added `broadcast' argument to the functions in silcd/server.[ch]
1724 silc_server_create_new_channel[_with_id] to indicate whether
1725 to send New Channel packet to primary router.
1727 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Added new function into the silcd/server.[ch] files:
1730 silc_server_create_new_channel_with_id to create new channel with
1731 already existing Channel ID.
1733 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1734 lib/silccore/silcpacket.h. This packet is used t send list of
1735 Set Mode payloads inside one packet. Server uses this to set
1736 the modes for the channels and clients on those channels, that it
1737 announced to the router when it connected to it. The protocol
1738 specification has been updated accordingly.
1740 * The silc_server_new_channel did not handle the packet coming
1741 from normal server as it normally does not send that. However,
1742 when it announces its channels it does send it. Implemented
1743 the support for that.
1745 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1746 into the file lib/silccore/id.h.
1748 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Fixed memory leaks in the functions silc_idlist_del_client,
1751 silc_idlist_del_channel and silc_idlist_del_server in the file
1752 silcd/idlist.c. All of those leaked like a sieve.
1754 * Fixed some small memory leaks in the client's function
1755 silc_client_notify_by_server.
1757 * Added functions into silcd/server.c: silc_server_announce_clients,
1758 silc_server_announce_channels and silc_server_announce_server.
1759 These functions are used by normal and router server to announce
1760 to its primary router about clients, channels and servers (when
1761 router) that we own. This is done after we've connected to the
1764 These functions effectively implements the following packet types:
1765 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1766 and SILC_PACKET_NEW_ID_LIST.
1768 * Added new functions into the silcd/packet_receive.[ch]:
1769 silc_server_new_id_list, silc_server_new_channel_list and
1770 silc_server_new_channel_user_list to handle the incoming
1771 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1773 * Added support of changing Channel ID in the function
1774 silc_server_replace_id. If the server that announces a channel
1775 to the router already exists in the router (with same name but
1776 with different Channel ID), router is responsible to send
1777 Replace ID packet to the server and force the server to change
1778 the Channel ID to the one router has.
1780 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1781 client that the Channel ID has been changed by the router. The
1782 normal server sends this to the client. Client must start using
1783 the new Channel ID as the channel's ID.
1785 Implemented handling of this new type into lib/silcclient/client.c
1786 into the function silc_client_notify_by_server.
1788 * Added new function silc_idlist_replace_channel_id into the files
1789 silcd/idlist.[ch] to replace the Channel ID.
1791 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Call silc_server_command_identify_check always when processing
1794 the IDENTIFY command in silcd/command.c
1796 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1799 send keepalive packets. The packet can be sent by clients,
1800 servers and routers.
1802 Added function silc_socket_set_heartbeat into the file
1803 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1804 If not set, the heartbeat is not performed. The actual
1805 heartbeat is implemented in the low level socket connection
1806 library. However, application is responsible of actually
1809 Added silc_server_send_heartbeat to send the actual heartbeat
1810 packet into silcd/packet_send.[ch]. Server now performs
1811 keepalive with all connections.
1813 * Added silc_task_get_first function into lib/silcutil/silctask.c
1814 to return the timeout task with shortest timeout. There was a bug
1815 in task unregistration that caused problems. TODO has been
1816 updated to include that task system must be rewritten.
1818 * The client library will now resolve the client information when
1819 receiving JOIN notify from server for client that we know but
1820 have incomplete information.
1822 * Rewrote parts of silc_server_remove_from_channels and
1823 silc_server_remove_from_one_channel as they did not remove the
1824 channel in some circumstances even though they should've.
1826 * Encryption problem encountered in server:
1828 The LEAVE command used to send the Channel Key packet to the
1829 router immediately after generating it. However, the code
1830 had earlier sent Remove Channel user packet but not immediately,
1831 ie. it was put to queue. The order of packets in the router
1832 was that Channel Key packet was first and Remove Channel User
1833 packet was second, even though they were encrypted in the
1834 reverse order. For this reason, MAC check failed. Now, this
1835 is fixed by not sending the Channel Key packet immediately but
1836 putting it to queue. However, this is more fundamental problem:
1837 packets that are in queue should actually not be encrypted
1838 because packets that are sent immediately gets encrypted
1839 actually with wrong IV (and thus MAC check fails). So, packets
1840 that are in queue should be encrypted when they are sent to
1841 the wire and not when they put to the queue.
1843 However, the problem is that the current system has not been
1844 designed to work that way. Instead, the packet is encrypted
1845 as soon as possible and left to the queue. The queue is then
1846 just purged into wire. There won't be any fixes for this
1847 any time soon. So, the current semantic for packet sending
1850 o If you send packet to remote host and do not force the send
1851 (the packet will be in queue) then all subsequent packets to the
1852 same remote host must also be put to the queue. Only after the
1853 queue has been purged is it safe again to force the packet
1856 o If you send all packets immediately then it safe to send
1857 any of subsequent packets through the queue, however, after
1858 the first packet is put to queue then any subsequent packets
1859 must also be put to the queue.
1861 Follow these rules and everything works fine.
1863 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * Added new function silc_server_remove_clients_by_server to
1866 remove all client entries from ID list when the server connection
1867 is lost. In this case it is also important to invalidate all
1868 client entires as they hold the invalid server entry. This
1869 fixes fatal bug when server has lost connection and will reconnect
1872 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Made some sanity checks to silc_server_daemonise like to check
1875 whether the requested user and group actually exists.
1877 * Added sanity check to SKE's silc_ske_responder_finish to check
1878 that the public and private key actually is valid.
1880 * Invalidate the client's nickname when receiving Replace ID
1881 packet and the Client ID is being replaced. This means that the
1882 server will query the nickname if someone needs it (client)
1885 * Sort the ID Cache in client library when the ID Cache data
1886 has changed (needs sorting).
1888 * Do not allow for SILC client to create several connections to
1889 several servers. The client does not support windows right now
1890 and generating multiple connections causes weird behaviour.
1892 Irssi-silc client does support windows and can handle several
1893 connections without problems, see: www.irssi.org and SILC plugin.
1895 * Fixed some places where client was added to the IDList. The
1896 rule of thumb is following (in order to get everything right):
1897 If the client is directly connected local client then the
1898 `connection' argument must be set and `router' argument must be
1899 NULL to silc_idlist_add_client function. If the client is not
1900 directly connected client then the `router' argument must
1901 bet set and the `connection' argument must be NULL to the
1902 silc_idlist_add_client function.
1904 * The funtion silc_server_packet_send_local_channel actually did
1905 not check whether the client was locally connected or not. It
1906 does that now. Fixed a bug related to LEAVE command.
1908 * Fixed Remove Channel User payload parsing bug in server's
1909 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1911 * The server's silc_server_save_channel_key now checks also the
1912 global ID list for the channel as it might not be in the local
1913 list. Fixed a bug related to LEAVE command.
1915 * Is this the end of the [<unknown>] buglet that has been lurking
1916 around for a long time? A little for loop fix in server's
1917 silc_server_command_whois_parse that is used by both IDENTIFY
1918 and WHOIS command. At least, this was a clear bug and a cause
1919 of one type of [<unknown>] buglet.
1921 * WHOIS and IDENTIFY commands call the function
1922 silc_server_command_[whois/identify]_check function even if
1923 we are not router server.
1925 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Added --with-gmp configuration option. If set the GMP
1928 is always compiled in the SILC source tree. If not set then
1929 it is checked whether the system has the GMP3 installed. If
1930 it has then the GMP won't be compiled (the system's headers
1931 and library is used), if it doesn't have it then the GMP is
1932 compiled in the SILC source tree.
1934 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Changed RSA private exponent generation to what PKCS #1
1937 suggests. We try to find the smallest possible d by doing
1938 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1939 not security fix but optimization.
1941 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added new config entry [Identity] to fork the server and run
1944 it as specific user and group. A patch from Bostik.
1946 * Imported Dotconf configuration library into lib/dotconf.
1947 This will be used to create the SILC configuration files later.
1948 It will appear in the distsribution after this commit.
1950 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * A big code auditing weekend happening. Auditing code for
1953 obvious mistakes, bugs and errors. Also, removing any code
1956 Removed files for being obsolete:
1958 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1959 inline in the file lib/silcutil/silcbuffer.h)
1961 o lib/silcutil/silcbufutil.c (the header has inline versions)
1963 Changed code to fix possible error conditions:
1965 o The buffer formatting routines now check that the destination
1966 buffer really has enough space to add the data. This applies for
1967 both buffer formatting and unformatting
1968 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1969 unformatting was changed to accomodate following rules:
1970 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1971 sent to the function while XXX_*STRING will not allocate or copy
1972 the data into the buffer. Instead it sets the pointer from the
1973 buffer into the pointer sent as argument (XXX_*STRING used to
1974 require that the pointer must be allocated already). This change
1975 makes this whole thing a bit more consistent and more optimized
1976 (note that the data returned in the unformatting with XXX_*STRING
1977 must not be freed now). The routines return now -1 on error.
1979 o Tried to find all code that use buffer_format and buffer_unformat
1980 and added return value checking to prevent formatting and
1981 especially unformatting errors and possible subsequent fatal
1984 o Changed ske->x and ske->KEY to mallocated pointers in
1985 lib/silcske/silcske.h. Fixed possible data and memory leak.
1987 o Added return value checking to all *_parse* functions. Fixed
1988 many memory leaks as well.
1990 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1991 so that buffer overflows would not happen. All code now also
1992 checks the return value as it can fail.
1994 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Added reconnection support to server if the normal server looses
1997 its connection to the router (for example if router is rebooted).
1998 The server performs normal reconnection strategy implemented
1999 to the server. Affected file silcd/server.c.
2001 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Added new packet type SILC_PACKET_SET_MODE that is used to
2004 distribute the information about changed modes (for clients,
2005 channels and clients channel modes) to all routers in the
2006 network. Updated the protocol specification accordingly.
2008 Added functions into silcd/packet_send.c and
2009 silcd/packet_receive.c: silc_server_send_set_mode,
2010 silc_server_set_mode.
2012 Added new files silcmode.[ch] into lib/silccore that implements
2013 the encoding and decoding of Set Mode Payload. Added new type
2014 SilcSetModePayload. Moved the definitions of different modes
2015 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2017 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Oops, a little mistake in server's connection authentication
2020 protocol. The protocol is not ended with FAILURE but with
2021 SUCCESS if the authentication is Ok. :) Affected file is
2024 * Implemented NICK_CHANGE notify handling in server in the file
2025 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2026 the local clients on the channel. After the changing nickname
2027 in router environment snhould work and the [<unknown>] nickname
2028 should appear no more.
2030 The silc_server_replace_id function that receives the Replace ID
2031 payload now sends the NICK_CHANGE notify type also in the file
2032 silcd/packet_receive.c
2034 * Changed WHOIS and IDENTIFY command to support the maximum amount
2035 of arguments defined in protocol specs (3328 arguments). This
2036 fixed a bug that caused problems when there were more than three
2039 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Added extra parameter, command identifier, to the
2042 silc_client_send_command so that explicit command identifier
2045 Changed that ID list routines uses specific command identifier
2046 when sending WHOIS/IDENTIFY requests to the server so that they
2047 can be identified when the reply comes back.
2049 Affected files lib/silcclient/command.[ch],
2050 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2052 * Added `sender' argument to silc_server_packet_send_to_channel
2053 to indicaet the sender who originally sent the packet to us
2054 that we are now re-sending. Ignored if NULL. Affected file
2055 silcd/packet_send.[ch].
2057 * Added some server statistics support in silcd/server_internal.h
2058 SilcServerStatistics structure and around the server code. Also
2059 send some nice statistics information when client is connecting
2062 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Fixed channel ID decoding in server's JOIN command reply in
2065 silcd/command_reply.c
2067 * Fixed braodcasting of replace ID payload to not to send it if
2068 we are standalone server in silcd/packet_receive.c.
2070 * Fixed all channel message sending routines to not to send
2071 packets to clients that has router set, since they are routed
2072 separately in the same function earlier. Affects file
2073 silcd/packet_send.c and all channel packet sending functions.
2075 * In USERS reply, res_argv[i] are not allocated, the table
2076 is allocated. Thus changed that free the table, not its
2079 * In server's whois_check and identify_check if the client is
2080 locally connected do not send any WHOIS commands - they are not
2083 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Fixed some minor bugs in client when sending WHOIS command. The
2086 arguments was in wrong order.
2088 * Removed statis function add_to_channel from server in
2089 silcd/command.c that was previously used with the joining but
2092 * Tested USERS command in router environment successfully with two
2093 routers, two servers and two clients.
2095 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Reorganized the USERS command and command reply in client library
2098 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2099 When the command is given by user we register a pending command
2100 callback that will reprocess the command after the reply has been
2101 received from the server. When reprocessing the packet we then
2102 display the information. Thus, the USERS information is displayed
2103 now in the command callback instead of in the command reply
2104 callback. The processing of the command is same as previously
2105 when server has sent the command reply in the JOINing process.
2107 * Added to USERS command in silcd/command_reply.c to join the client,
2108 we didn't use to know about, to the channel after we've created
2109 a client entry for it. Also, for clienet we did know already still
2110 check whether it is on the channel or not and add it if not.
2112 * Removed silc_server_command_join_notify as the function and its
2115 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Changed the client's pending command handling to the same as the
2118 server's pending command handling. It is also now possible to
2119 execute command reply functions from other command reply
2120 function as the function callbacks for commands and command
2121 replies are one and same. The pending commands are not static
2122 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2123 in client connection context. Thus, pending commands are server
2124 connection specific as it is convenient.
2126 Changed the function silc_client_command_pending and
2127 silc_client_command_pending_del and added new function
2128 silc_client_command_pending_check. Removed the
2129 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2132 * Added cmd_ident, current command identifier, to the client
2133 connection context in lib/silcclient/client.h to keep track on
2134 command identifiers used in command sending. Client's command reply
2135 function handling now supports the mandatory command identifiers.
2137 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2138 funtions in client to fully support pending command callbacks.
2140 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2141 as one of the arguments to the application in the command reply
2144 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2145 before first releasing SILC but came back. Now it is removed again
2146 and should come back nomore. The FORWARDED flag was used only
2147 by the JOINing procedure by forwarding the command packet to router.
2148 Now, the JOINing procedure has been changed to more generic (due
2149 to various router environment issues) and FORWARDED is not needed
2150 anymore for anything. The protocol specification is yet to be
2153 Now, removed silc_server_packet_forward from server and the flag
2154 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2156 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Renamed NAMES command to USERS command. The NAMES was named that
2159 due to historical reasons. Now it is renamed. Also, rewrote
2160 parts of the USERS command. The nickname list is not sent anymore
2161 by the server. Only Client ID and mode lists are sent in the USERS
2162 command. Changed this also to the protocol specification.
2164 The client now resolves the names and stuff after it receives
2165 the USERS list from the server when joining to the channel.
2167 * WHOIS and IDENTIFY commands has been changed to support multiple
2168 Client ID's per command. One can now search for multiple users
2169 in the network by sending only one WHOIS or IDENTIFY command.
2170 Changed the code and the protocol specifications.
2172 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2173 uses silc_server_command_whois_parse to parse the request. */
2175 * If normal server, do not parse the WHOIS and IDENTIFY requests
2176 before sending it to the router. Saves some time.
2178 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Fixed JOIN command on client library. Wrong number of arguments
2181 used to crash the client.
2183 * Added silc_server_channel_has_global function to check whether
2184 channel has global users or not.
2186 * Added silc_server_channel_has_local function to check whether channel
2187 has locally connected clients on the channel.
2189 * The silc_server_remove_from_one_channel now checks whether the
2190 channel has global users or not after given client was removed from
2191 the channel. It also checks whether the channel has local clients
2192 on the channel anymore. If it does not have then the channel entry
2193 is removed as it is not needed anymore.
2195 * The silc_server_notify now checks on JOIN notify whether the joining
2196 client is one of locally connected or global. If it is global then
2197 the channel has now global users on the channel and that is marked
2198 to the channel entry. Also, it now saves the global client to
2199 global list who is joining and JOINs it to the channel. This is
2200 for normal server, that is.
2202 Changed silc_server_send_notify_on_channel,
2203 silc_server_packet_relay_to_channel and
2204 silc_server_packet_send_to_channel check if we are normal server
2205 and client has router set (ie. global client) do not send the
2206 message to that client, as it is already routed to our router.
2208 * Implemented LEAVE notify type handling in silc_server_notify
2211 * Tested LEAVE command in router environment successfully. Tested
2212 with two routers, two servers and two clients.
2216 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2218 * Implemented SIGNOFF notify type handling in silc_server_notify
2221 * silc_server_remove_id now removes the client entry from all channels
2222 it has joined and thusly sends SIGNOFF notify type.
2224 * Rewrote the NAMES list generation in server by removing two excess
2225 loops. The lists are created now inside one loop.
2227 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * silc_server_remove_channel_user checks now also global list
2230 for channel and client.
2232 * silc_server_new_channel_user checks now both local and global
2233 list for channel and client. Fixed a bug in client id decoding.
2234 Used to decode wrong buffer.
2236 * silc_server_channel_message checks now both local and global
2237 list for channel entry.
2239 * Tested channel joining (hence JOIN) in router environment
2240 successfully. Tested with two routers, two servers and two
2243 * Tested channel message sending in router environment successfully.
2245 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Added silc_server_save_channel_key into server.[ch] to save the
2248 received channel key in Channel Key payload processing. It is
2249 also used in JOIN command reply handling.
2251 Equivalent function silc_client_save_channel_key added into
2252 client.[ch] into client library.
2254 * Changed JOIN command reply to send information whether the channel
2255 was created or not (is existing already) and the channel key
2256 payload. Changed protocol specs accordingly.
2258 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2259 the request was sent by ID and not by nickname. Crashed on
2262 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2265 now correctly save the received data.
2267 * silc_server_free_sock_user_data now notifies routers in the
2268 network about entities leaving the network.
2270 At the same time implemented functions silc_server_remove_id
2271 and silc_server_send_remove_id to receive and send REMOVE_ID
2272 packets. The packet is used to notify routers in the network
2273 about leaving entities. The ID removed will become invalid in
2276 * Added function silc_idlist_del_server into server. Removes and
2277 free's server entry from ID list.
2279 * silc_server_private_message function now checks, if we are router,
2280 that the destination ID really is valid ID, naturally.
2282 * In router when NEW_ID packet is received (for new client) the
2283 hash of the Client ID is saved in the ID Cache but the
2284 client->nickname is set to NULL, instead of putting the hash
2287 IDENTIFY command now also checks that client->nickname must be
2288 valid. If it is not if will request the data from the server who
2289 owns the client. Added new function
2290 silc_server_command_identify_check.
2292 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2293 to set the command to already allocated Command Payload.
2295 * Tested private message sending in router environment with two
2296 routers, two servers and two clients. Fixed minor bugs and now
2299 * Fixed segfault from client's NAMES command. Used to crash if
2302 * Forwarded packets must not be routed even if it is not destined
2303 to the receiver. Changed server code comply with this.
2305 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Added `require_reverse_mapping' boolean value to ServerParams
2308 structure. If TRUE (not default) the server will require that
2309 the connecting host has fully qualified domain name.
2311 If the reverse mapping is not required and hostname could not be
2312 found the IP address is used as hostname.
2314 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Implemented version string checking to both client and server.
2317 The check is incomplete currently due to the abnormal version
2318 strings used in development version of SILC.
2320 * Changed all command functions in server to use the new
2323 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Changed char *data to unsigned char *data in ID Cache system to
2326 support binary data as ID Cache data. Changed code to support
2327 binary data in lib/silccore/idcache.c.
2329 * Renamed silc_server_packet_relay_command_reply to
2330 silc_server_command_reply as it is normal packet receiving
2331 function. Rewrote the function to accept command replys for
2332 servers and not only for clients.
2334 * Mark remote router always as registered server if we are connecting
2335 to it. Otherwise, commands sent by the router to us are ignored.
2337 * All ID List find routines now returns the ID Cache Entry pointer
2338 as well if requested.
2340 * WHOIS command works now in router environment, tested with two
2341 routers, two servers and two clients.
2343 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2344 in router environment (as it is almost equivalent to WHOIS) but
2345 hasn't been tested thoroughly. Added new functions:
2347 silc_server_command_identify_parse
2348 silc_server_command_identify_send_reply
2349 silc_server_command_identify_from_client
2350 silc_server_command_identify_from_server
2352 * Disabled route cache adding because adding two different ID's with
2353 same IP replaces the old cache entry thus giving wrong route.
2354 The entry->router->connection is always the fastest route anyway
2355 so route cache may not be needed. Of course, new routes maybe
2356 established after receiving the ID when the entry->router->connection
2357 might not be anymore the most optimal.
2359 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Add route cache for received ID for fast routing.
2363 * Added silc_server_packet_route to route received packet on router
2364 that is not destined to us.
2366 * Renamed silc_server_get_route to silc_server_route_get.
2368 * Added id_string and id_string_len fields into SilcServer to
2369 include encoded ServerID for fast comparing without excess
2370 encoding of the ID's.
2372 * Cleaned up WHOIS command on server side. Added following static
2375 silc_server_command_whois_parse
2376 silc_server_command_whois_check
2377 silc_server_command_whois_send_reply
2378 silc_server_command_whois_from_client
2379 silc_server_command_whois_from_server
2381 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2382 arguments in command replies. All command functions should be
2383 updated to use this macro.
2385 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Minor typo fixes on command reply handling on server.
2389 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Added silc_server_command_add_to_channel internal routine to add
2392 the client to the channel after router has created the channel and
2393 sent command reply to the server.
2395 * Added generic silc_server_send_command to send any command from
2398 * Use static buffer with ID rendering instead of duplicating data.
2400 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Fixed a channel user mode bug when joining to a channel server gave
2403 everybody channel founder rights, oops.
2405 * We mark ourselves as the router of the incoming server connection
2406 if we are router ourselves. This way we can check in some packet
2407 sending functions whether it is locally connected server. For
2408 incoming router connections we put NULL.
2410 * For router sending packets locally means now always sending the
2411 packet cell wide; to local clients and local servers. For normal
2412 server sending packet locally means sending it to only local
2415 * Fixed the JOIN command to really work in router environment. If the
2416 channel is created it is always created by the router. Router is
2417 also responsible of making the initial joining to the channel,
2418 sending JOIN notify to the sending server and distributing
2419 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2420 does not exist server doesn't do anything else but forward the
2421 command to the router which performs everything.
2423 * Added silc_server_send_channel_key function to send the Channel Key
2426 * Added silc_server_create_channel_key to create new channel key. The
2427 channel key is now re-generated everytime someone joins or leaves
2428 a channel, as protocol dictates. Note: channel->key_len is the
2431 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2434 packet_receive.[ch] to separate packet sending and receiving
2435 routines. The server.[ch] now includes everything else including
2436 actual packet processing (writing and reading data) and other
2439 Renamed silc_server_private_message_send_internal to
2440 silc_server_send_private_message. The routine is still though
2441 used only to relay private messages as server does not send
2442 private messages itself.
2444 Renamed silc_server_new_channel to silc_server_create_new_channel
2445 and added new function sicl_server_new_channel that handles the
2446 incoming New Channel packet. Added also new sending function
2447 silc_server_send_new_channel to send New Channel Payload.
2449 * Added new function silc_server_notify to process incoming notify
2450 packet to the server/router. Server may then relay the notify
2451 to clients if needed.
2453 * Added new function silc_server_new_channel_user to process incoming
2454 New Channel User packet. Router will redistribute the packet and
2455 send JOIN notify to its local clients and locally connected servers
2456 if needed. Normal server will send JOIN notify to its local client
2457 on same channel when received this packet. Added also corresponding
2458 sending function silc_server_send_new_channel_user to sent the
2461 * Added boolean route argument to send_notif_to_channel and
2462 packet_send_to_channel functions to attempt to route the packet
2463 if it is TRUE and send only locally if it is FALSE.
2465 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * silc_server_replace_id now broadcasts the received replace ID
2468 packet if it is not broadcast packet already. The router must
2469 broadcast to inform other routers about changed ID.
2471 * Added backpointer to server's router into SilcServer context in
2472 silcd/server_internal.h.
2474 * Fixed silc_server_packet_broadcast to send correct broadcast
2477 * The channel key is now distributed to the local client as soon
2478 as it is received from the router (in router environment) so that
2479 no other packet may be sent for the channel until client has
2482 * silc_server_remove_channel_user now broadcasts the received
2483 Remove Channel User packet if it is not broadcast packet already.
2484 The router must broadcast to inform other routers about removed
2487 * Added users field into SilcPacketContext that is a reference count
2488 of the context. One can increase the reference count by calling
2489 silc_packet_context_dup which is now changed to just increase the
2490 reference count instead of duplicating the data. The reference
2491 count is decresed by calling silc_packet_context_free that will
2492 free the data after the reference count hits zero.
2494 For now on the packet context and everything allocated into it
2495 (including the raw packet from network) must be freed by calling
2496 the new silc_packet_context_free function. Added also new function
2497 silc_packet_context_alloc that must be used now to allocate the
2498 context. This also means that if a routine is asynchronous from
2499 silc_[client/server]_packet_parse_type the packet context must
2500 be duplicated by calling silc_packet_context_dup. Otherwise it
2501 gets free'd after silc_[client/server]_packet_parse_type returns.
2502 Also, one must remember that if packet is duplicated then its
2503 reference count must be decresed by calling the free function as
2504 many times as it was duplicated.
2506 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2507 from both client and server.
2509 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Made joining to a channel working in router environment.
2513 * Cleaned up JOIN command on server side and create function
2514 silc_server_command_join_channel internal routine to make the
2517 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Changed silc_command_pending list to SilcDList. Also, added
2520 `ident' field to SilcServerCommandPending structure to identify
2521 the reply and to call correct callback.
2523 Added silc_server_command_pending_check function to replace the
2524 corresnponding macro. The silc_command_pending list is not
2527 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2528 to set identifier to previously allocated Command Payload. It
2529 is used to set identifier for command when resending Command
2532 * Added silc_command_payload_encode_payload to encode Command
2533 Payload buffer from SilcCommandPayload structure.
2535 * Added silc_argument_payload_encode_payload to encode Argument
2536 payload buffer from SilcArgumentPayload structure.
2538 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Changed WHOIS command to support router connection on server side.
2541 The whois request is always sent to router unless the server is
2542 standalone server. After server has received the reply from the
2543 router will it send the reply to the client.
2545 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2546 broadcast received broadcast packet. The function is used only
2547 by router. The broadcast packet is always sent to the router's
2550 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2551 render given ID to printable string, for log files for example.
2553 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * Made basic router to router connections working. At least they
2556 can now connect to each other but nothing really works the way
2557 they are supposed - yet.
2559 * Added new initiator token to RouterConnection configuration
2560 file in silcd/serverconfig.[ch]. It is used to tell whether we
2561 are the initiator to the remote router or whether we'll expect
2562 the other end to connect.
2564 * Moved registering of listener task to silc_server_init, hence
2565 the server starts listenning as soon as it is run, even if it
2566 does not have connections to other routers. Let's see how well
2569 * Changed default connection retry timeouts for more suitable in
2572 * Removed cipher and such arguments from silc_idlist_add_client
2573 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2574 Added new function silc_idlist_add_data to add the keys and stuff
2577 * Added SilcIDListData structure and added it to SilcClientEntry
2578 and SilcServerEntry as their first field in the structure. This
2579 way we can explicitly cast the ID entries to the SilcIDListData
2580 structure and get common data for the entries. In past, we had
2581 to first check what type of connection it is and then cast it to
2582 correct ID entry type. Now, we can directly cast the opaque
2583 pointer to the SilcIDListData (no matter what ID entry it actually
2584 is) and get the data needed.
2586 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2589 in some circumstances even if threre were timeout tasks, though not
2590 IO tasks, but tasks anyway. Now fixed.
2592 * Defined SilcServerConnection structure to hold connection specific
2593 stuff about directly connected servers and routers. The definition
2594 is currently in silcd/server_internal.h. I thought about having
2595 a bit more important role fro this struct but for now it is used
2596 only when connecting to other server (or router actually).
2598 * Added connecting retry support in server when connecting to
2599 router(s). The retry feature implement exponential backoff
2600 algorithm. Also, added SilcServerParams structure to hold default
2601 parameters for server. For now, it include these retry settings
2602 and are hard coded. After server is moded to be as Silc Server
2603 Library this structure will be more important.
2605 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Changed client librarys channel->clients table to SilcList and
2608 changed code accordingly.
2610 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Changed client's channel table to SilcList and changed code
2613 accordingly. Also changed SilcChannelClientEntry to include back-
2614 pointer to the channel so that client entry can use that structure
2615 as list as well and we have fast cross-reference to the channel.
2616 This change dramatically decreased the complexity of channel
2617 handling with client entry and vice versa (removed one extra
2618 loop when searching for channel entry from many functions).
2620 * Changed server->sim from table to SilcDList and changed code
2623 * NAMES command can now be used from user interface. It will show
2624 the user list on the channel, neatly.
2626 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2627 Code now saves realname of the user if it becomes available.
2629 * Renamed configure.in to configure.in.pre and made ./prepare
2630 script to automatically add correct version string to
2631 configure.in which it creates from configure.in.pre.
2633 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * NAMES command reply now shows users mode with the nickname when
2638 * Moved silc_client_ch[u]mode[_char] functions from
2639 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2640 place sucks, they are utility functions and should be in some
2643 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2645 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2648 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added TRQ (efficient deque and list library) into lib/trq. This is
2653 a very good list library that is currently used in the SILC. Defined
2654 SilcList API over the library because I didn't like the API very
2655 much. See lib/trq/silclist.h for the API and examples of how to
2656 use the API. Fixed various places in the code to use the new
2657 SilcList API. The SilcList is meant for lists that has a structure
2658 already defined as a list. It is not suitable to add just some
2659 context to the list (in TRQ, the context is the list actually).
2661 So, I defined SilcDList that can be used for the purpose where
2662 predefined list structure does not exit. This can be used as
2663 such list. Now some context just can be added to the SilcDList.
2664 Currently this list is not used in the SILC just yet, though there
2665 are a lot places where this can replace dynamically allocated
2666 tables and I will fix these places, later, to use SilcDList.
2667 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2668 and use TRQ internally).
2670 Also fixed some annoying warning messages that the original TRQ
2671 code generated. Also minor changes to TRQ's Makefile.in.
2673 * Added support for querying by Client ID to both WHOIS and
2674 IDENTIFY commands into server, as required by the protocol.
2676 * Removed method function pointers from SilcBuffer structure. They
2677 weren't used to anything and just increased the context size for
2678 no good reason. This change also made silc_buffer_alloc and
2679 silc_buffer_free functions inline functions.
2681 * Disabled command flooding detection support until it's fixed so
2682 that it accepts commands in but does not execute them more than once
2685 * Added silc_net_localhost(), to return local hostname, into
2686 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2687 that must be initialized before calling silc_client_init.
2689 * Added new function: silc_server_send_notify_on_channels to send
2690 notify messages to all channels client has joined. It is assured
2691 that the message is sent only once per client.
2693 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2694 lib/silcutil/silcutil.[ch] as silc_format function. The new
2695 function is generic and is used by server as well, not only by
2696 the logging routines.
2698 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2699 the provided version string was not acceptable. Added new function:
2700 silc_ske_check_version into lib/silcske/silcske.h. The function
2701 must be implemented by the application (client or server) and it
2702 does not reside in the SKE library. The function checks the version
2703 string remote end sent.
2705 * Added back pointers (to opaque context and to SilcSocketConnection)
2706 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2708 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2709 duplicate packet context structure.
2711 * Changed `notify' client operation to send same arguments as client
2712 receives from server except for ID's. ID's are mapped to correct
2713 ID entry and that is returned. Also, if channel entry is not sent
2714 by server but the notify is for channel the channel entry is sent
2715 to application (otherwise application doesn't know that it is for
2716 channel (library gets it from packet's Destination ID)).
2718 * Added silc_client_remove_from_channels into client library to
2719 remove a client from all channels it has joined to. Used when
2720 received SIGNOFF notify from server. Added also new function
2721 silc_client_replace_from_channels to replace old ID entry with
2722 new ID entry on all channels. Used when received NICK_CHANGE
2725 * Fixed ID Cache list handling in silc_idlist_get_client in
2726 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2727 to get (or query) client by ID.
2729 * Updated TODO list.
2731 * Added connection authentication status message defined by the
2732 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2733 support for these into the code in client and server side.
2735 * Added generic function silc_client_send_command to send any command
2736 with variable argument list. Application should use this function
2737 to send commands if the command functions provided by the library
2738 does not suite for the application's user interface needs.
2740 * Added new `failure' client operation. Application is notified about
2741 received failure packet if client is executing a protocol. In this
2742 case the protocol's execution has failed.
2744 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2745 is required by the protocol.
2747 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2748 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2751 * Added status flag to SilcSKE object to indicate realtime status
2752 of the SKE protocol.
2754 * Application receives now exactly same command reply arguments as
2755 the library receives from server. However, if ID is received the
2756 corresponding ID entry is returned to the application (eg. Client
2757 ID is mapped to correct SilcClientEntry entry and that is returned).
2758 Changed command_reply client operation due to this change.
2760 * Changed all ID's in commands and in command replys as ID Payloads.
2761 Change affected both client and server side codes.
2763 All ID's sent in SILC network (with execption of ID's in SILC
2764 Packet header) are sent in ID Payload to support variable length
2767 * Server now notifies nick changes and notifies all clients on
2768 the channels about the new nickname (about the new Client ID,
2771 * Implemented CMODE command to change channel modes. Supports all
2772 channel modes defined by the protocol specs except ban and invite
2773 lists. (Also, private channel key mode is supported but support for
2774 setting private channel key in client is missing, thus, this mode
2775 has no effect on client side (except that server requires that the
2776 client uses private channel key and normal channel traffic does not
2779 Also, invite mode works per se, but INVITE command does not work
2780 yet correctly, so you can set channel as invite only channel but
2781 inviting clients to the channel does not work (it is yet to be
2782 thought what's the best way to do it).
2784 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2785 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2786 Implemented CUMODE command to change user's mode on the channel.
2787 Supports all modes defined by the protocol specs.
2789 * Added NAMES command reply to return users modes on the channel.
2791 * Removed unnecessary and slow ciphers from lib/silccrypt.
2793 * Set SO_KEEPALIVE option to connection sockets by default.
2795 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2797 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2798 redefined the Notify Payload into protocol specs.
2800 * Added silc_id_payload_parse_id to get ID directly from raw
2803 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2806 accept searching by Client ID as well.
2808 * Added support for LEAVE and SIGNOFF notify types in client library.
2810 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2811 to parse ID Payload from raw data.
2813 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2815 * Added flags parameter into silc_ske_assemble_security_properties
2816 function in lib/silcske/silcske.[ch].
2818 * Changed notify client operation to fit better for notify messages
2819 sent by server. The notify payload received from server is now
2820 passed to the application (after parsing it to SilcNotifyPayload).
2821 It is application's responsibility to retrieve the arguments
2822 from the payload and show the message the way it wants. The message
2823 sent by server is implementation specific.
2825 * Changed public keys to comply with the protocol specification.
2826 Old public keys are not supported anymore and are not compatible.
2828 * Removed nickname from Channel Payload as the latest draft removed
2829 it. The client must resolve the nickname from the NAMES command
2830 reply received when it joined the channel.
2832 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2834 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Fixed some errors in protocol specification drafts.
2838 * Created lib/silccore/silcnotify.c to implement Notify Payload
2839 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2840 generic payloads described by protocol specifications. The file
2841 includes implementations for ID Payload and Argument Payload.
2843 * Changed Command Payload implementation to use the new Argument
2844 Payload. Changed command_xxxx_payload to command_payload_xxxx
2845 to comply with SILC coding conventions.
2847 * Added suppport for Argument Payload handling in Notify Payload
2848 implementation as protocol requires it. Added the new support
2849 into server and client lib as well.
2851 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2853 * Added support for multiple nicknames on same channel. [n] is
2854 added locally to the nickname if there are more than one same
2855 nicknames on the channel.
2857 * Server now sends all nicknames that matched WHOIS request.
2858 Client also shows the list received from server.
2860 * Added TOPIC command to client side. User can now set and show
2861 current topic on channel.
2863 * Added MOTD command to client and server. Also, server sends the
2864 motd when client connects to the server.
2866 * Changed version strings to comply ISO 8601.
2868 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Fixed protocol error handling in client library. It should now
2871 cope even if the SKE fails for some reason.
2873 * Made new protocol specification drafts for submitting to IETF.
2875 * Implemented TOPIC command to server in silcd/command.c.
2877 * Added two new notify types into lib/silccore/silcnotify.h:
2878 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2879 notify nickname change and topic setting/change on a channel.
2881 * API change of command_reply operation in client library. The
2882 application gets now the status type received from server as well.
2884 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2888 * Cras fixed and optimized the packet handling even further and
2889 it should work now. Minor change to the prototype of function
2890 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2892 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Added new function into lib/silcutil/silcschedule.[ch]:
2895 silc_schedule_with_fd to select() a specified fd. The function
2896 returns after timeout expires or data arrives or goes. The
2897 function is used by packet routines to wait that all data is
2898 received from network.
2900 * Fixed data reading from network in lib/silccore/silcpacket.c.
2901 The code now assures that all data is read from the fd and then
2902 continues packet processing. This was a bug fix since the code
2903 used to drop some data in some circumstances.
2905 * Added new function into lib/silcclient/client.[ch]:
2906 silc_client_start_key_exchange to start key exchange after
2907 connection has been established to server. The code internally
2908 now uses this funtion but its main purpose was to provide it
2909 for applications that perform their own connecting. After
2910 application has created a connection it merely calls this
2911 function to start the key exchange between client and server.
2912 The library takes care of everything else after that.
2914 Updated also lib/silcclient/README to explain the usage of
2917 * Do not send to application information that connection has
2918 been established. Application gets notified it by connect
2921 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Applied cras's patch to add silc_schedule_one function. The
2924 function runs scheduler once and returns.
2926 * Fixed the scheduler after cras messed it up. The timeout
2927 handling works now as it's supposed to work.
2929 * Added into lib/silccore/ silcnotify.h to include notify
2930 message types support. Changed silc_server_send_notify*
2931 functions, in server.[ch], to support those new notify types.
2932 Added the support for the notify types into client library,
2933 as well. Added new notify client operation into ops.h in
2936 * Changed silc_server_packet_send_to_channel to send normal
2937 packets instead of just channel message packets. The function
2938 is now used to send the notify packets to channels. It is not
2939 used to send channel message packets anymore, as server never
2942 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2943 va_arg()s as it seems to require it nowadays. I guess, if SILC
2944 is compiled with older va_arg() the new code should work anyway.
2946 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Splitted core library. Core library (lib/silccore) includes
2949 now only SILC protocol specific core (and common) components.
2950 Created new utility library (lib/silcutil) that includes more
2951 generic purpose stuff. The stuff for util library was taken
2952 from the old core library. This was minor and easy split.
2954 * Created SILC Client Library (lib/silcclient) that includes
2955 implementation of the SILC client without user interface. This
2956 was major move from silc/ directory. The code has been changed
2957 so that it is transparent towards the user interface. The
2958 silc/ directory includes now the same user interface as before
2959 and it uses the new client library. Read lib/silcclient/README.
2960 Basicly, the client library performs everything else related
2961 to SILC except user interface handling. Also, configuration
2962 files are considered to be part of user interface and library
2963 does not handle them.
2965 This change also changed a lot of structures, function naming etc.
2966 Most important change was that SilcClientWindow object was
2967 renamed to SilcClientConnection in the client library. Created
2968 also new file lib/silcclient/ops.h. Also added new files
2969 silc/local_command.[ch] and silc/client_ops.[ch].
2971 All these changes were made to make it easier for user interface
2972 designers to create what ever user interface for the SILC client
2975 It is also expected that the server will be moved to lib
2976 directory as well and SILC Server Library will be created;
2977 sometimes in the future.
2979 * Removed Local commands from lib/silccore/silccommand.h as
2980 they are application specific and new client library does not
2981 handle any of those anymore.
2983 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2984 old client implementation in silc/.
2986 * Added support for callback functions in SILC_LOG_* macros.
2987 Application can now set its own callbacks that will be called
2988 instead of using the default functions that will always print
2989 the debug messages to stderr (or stdout). Also, debugging can
2990 now be disabled by setting silc_debug to FALSE and re-enabled by
2991 setting it to TRUE. Note, that logging will still work even
2992 if debugging is disabled.
2994 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2995 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2996 silc_log_reset_debug_callbacks.
2998 * To enable debugging in silc client one must give now -d
2999 option on command line.
3001 * Changed silc_schedule_init to automatically allocate task queues
3002 if they are not allocated before calling it.
3004 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Added GMP 3.1 into math library.
3008 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3010 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3011 a channel in SILC network. The packet is used by servers and
3012 routers to notify other routers that user has left a channel.
3013 This little feature was missing until now. Added the feature
3014 to protocol specification as well.
3016 Added functions: silc_server_send_remove_channel_user and
3017 silc_server_remove_channel_user into server.[ch].
3019 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3020 lib/silccore/silcpacket.h. However, they are not implemented
3023 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Fixed joining to a channel and sending channel messages
3026 between server and router. The channel message sending should
3027 now work inside a cell.
3029 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Fixed the private message sending between server and router.
3032 The private message sending should now work inside a cell.
3034 * Added silc_server_replace_id into server.[ch] to replace
3035 existing ID in the SILC network.
3037 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3038 and silc_idlist_replace_server_id into idlist.[ch] in server.
3040 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Fixed the server to server connections. Server can again now
3043 connect to router. Router to router connections probably does
3046 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added dynamic protocol registering support. Now protocols can
3049 registered and unregistered on the fly. Patch by cras.
3051 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3053 * Added lib/contrib directory to hold routines that some platforms
3054 don't have but are needed by SILC.
3056 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3057 into lin/contrib to provide getopt() and getopt_long() for
3058 those who don't have it.
3060 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Added AWAY command to client. When away message is set and
3063 client receives a private message packet the client automatically
3064 replies to the sender with the away message.
3066 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3067 bug seemed to be the cause of recent problems when compiling
3070 * Added version detection support to SKE protocol specification
3071 and added the new changes to the SKE implementation as well.
3072 There were other minor changes in the SKE protocol as well.
3074 Many changes in lib/silcske/silcske.[ch] and in
3075 lib/silcske/payload.[ch].
3077 * Added ^U functionality, clear input line. Patch from cras.
3079 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Mainly small bugfixes on core library. Fixed some debugging
3082 logging and buffer overflow in silclog.c.
3084 * Updated config.sub and config.guess on the distribution tree.
3086 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Added command lagging support in server. Client may execute
3089 commands now only once in two seconds.
3091 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Optimized packet reception. MAC computation and checking is now
3094 also more optimized. A lot previously duplicated code is now
3095 used as generic by both client and server.
3097 * Fixed key pair generation in clientutil.c
3099 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Added into lib/silccore/silcbufutil.[ch] new function;
3102 silc_buffer_realloc.
3104 * Moved generic packet sending/encryption functions to
3105 lib/silccore/silcpacket.[ch] from client and server. Some
3106 rewriting of the functions.
3108 * Moved all generic packet reception/decryption functions to
3109 lib/silccore/silcpacket.[ch] from client and server. The
3110 packet processing is now much cleaner in both client and server.
3111 These were major changes in both client and server.
3113 * Created many common functions in server to do packet sending.
3114 Previously code were duplicated a lot, this has been removed
3117 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Rewrote major parts of the ID cache system. Don't know
3120 whether it is better now or not but at least the API is more
3123 * Major rewrite on ID cache stuff on client because of the ID
3124 cache API changes. Added idlist.c to client.
3126 * Also major rewrite on ID cache stuff on server as well.
3127 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3128 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3129 in hand, instead they are all put into the ID cache system now.
3130 All server_idlist_* routines uses ID cache now instead of
3131 traversing its own lists (those lists does not exist anymore).
3132 SilcIDList though still exists. Also, SilcXXXEntry's are
3135 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Finally made the SKE implementation compliant to the protocol
3138 specification. All mp integers are now binary encoded as
3139 opposed being HEX encoded.
3141 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3144 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3145 functions: silc_[encode/decode]_pem. Also added function
3146 silc_encode_pem_file to PEM encode with newlines ('\n') for
3149 * SILC public keys are now encoded either PEM or binary. Same
3150 option is for private keys as well. By default private keys
3151 are binary encoded and public keys PEM encoded. Silly HEX
3152 encoding were removed.
3154 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3155 function to create fingerprints.
3157 * Fixed a bug in SHA1; does not change the original data anymore.
3159 * Partly implemented INFO command on client and server side.
3160 Fixed CLEAR command. Changes to SERVER command; show current
3161 server(s) when giving command without arguments. Added
3162 VERSION command to client.
3164 * Added check to server that unregistered connections cannot
3165 execute commands (unless it is specificly allowed).
3167 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed screen refresh.
3171 * Fixed channel joining bug from client. On some circumstances
3172 client tried to join to a channel it had already joined.
3174 * Added public key verification process into client's protocol.c.
3175 The client now verifies the public key from user and saves
3176 it into ~./silc/serverkeys/ directory.
3178 Added into: clientutil.[ch]: silc_client_verify_server_key.
3180 * Changed SKE protocol's silc_ske_initiator_finish function
3181 to accept callback function that verifies the received public
3182 key. Removed old silc_ske_verify_public_key function.
3184 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3187 silc_pkcs_private_key[_data]_set.
3189 * Made the password and public authentication more cleaner in
3190 server's protocol.c.
3192 * Removed historic and obsolete protocol `channel_auth' from
3193 both client and server.
3195 * Removed wrong way of sending command status messages from
3196 server to client in server's command.c. The old way violated
3197 protocol specification.
3199 Changes to silccore/silccommand.[ch]: removed
3200 silc_command_encode_status_payload -> not needed anymore,
3201 changed silc_command_encode_payload_va to accept extra
3202 argument on variable argument list. The argument type must
3203 now be provided to the function. Also, added new function:
3204 silc_command_encode_reply_payload_va which is same as
3205 normal command_encode_payload_va except command status type
3206 is provided as extra argument.
3208 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Added ~./silc directory handling. The directory includes the
3211 public and private keys for the client.
3213 Added silc_client_check_silc_dir, silc_client_create_identifier
3214 and silc_client_load_keys.
3216 * Implemented SILC protocol compliant public key. Added public
3217 and private key saving to and loading from files.
3219 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3220 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3221 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3222 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3223 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3225 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3226 silc_pkcs_load_[public/private]_key.
3228 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Added silc_server_get_route (route.[ch]) to get connection
3231 data for the fastest route for given ID.
3233 * Implemented INVITE command on client and server. The command
3234 were re-defined in the SILC Protocol Specification and the
3235 implementation now complies with the specification.
3237 * Implemented PING command on client and server.
3239 * Implemented NAMES command on client and server. The server side
3240 supports currently only normal server not router server yet.
3241 Some changes to NAMES definition in SILC protocol specification.
3243 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Implemented LEAVE command on client and server.
3247 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3248 again. This change was made to the protocol as well. Server
3249 should not violate the protocol specification anymore.
3251 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3254 was tested. SOCKS4 was not but should work anyway.
