3 * Do not parse packets with different timeout when protocol
4 is active -> may cause problem with rekey. Affected file
7 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Added printing of error messages during SKE protocol from the
10 failure packet sent by server during SKE. Affected file
13 * Removed the client's failure_callback handling with timeout
14 and handle it immediately when received.
16 * The SKE library returned wrong type in SUCCESS and FAILURE
17 packets. They must be 32 bit MSB not 16 bit MSB.
19 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Ok, rewrote the logic of the re-key and now it seems to work.
22 I tested it on high traffic with frequent re-keys without
23 problems. Added hmac_receive (and renamed hmac to hmac_send)
24 in SilcClientConnection in lib/silcclient/client.h and
25 in SilcIDListData in silcd/idlist.h. Also, removed the
26 SilcPacketParserContext's cipher and hmac fields as they are
27 not needed anymore and actually caused some problems when
28 the ciphers and hmac's changed underneath the packet parser.
30 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * If re-key protocol is active then process the incoming packets
33 synchronously since we must assure that icoming packets encrypted
34 with the old key is processed before the new keys is set to
35 use. This is true other packets than for REKEY packets.
36 Affected file silcd/server.c. The same was done to client library
37 as well, affected file lib/silcclient/client.c.
39 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Fixed bug in client and server to accept the force send if
42 the packet is send from silc_[server/client]_packet_process
43 function. Otherwise the packets are never delivered, oops.
45 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * Disable force sending of packets when REKEY protocol is active.
48 We must assure that no packet is sent directly when rekey is
49 performed. All packets must be sent through packet queue.
50 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
51 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
52 function is silc_[server/client]_packet_send_real to check
55 * Replaced the SIM paths from example config files to
56 /usr/local/modules. Also, make install creates now
57 /usr/local/silc/logs directory to hold all the SILC server
60 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Made the configure.in.pre work on Solaris. Patch by salo.
64 * Made all ciphers compatible with non-x86 machines. Defined
65 CBC mode macros into lib/silccrypt/ciphers_def.h.
67 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Fixed the make install.
71 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * When MAC computation fails the silc_packet_decrypt returned 0
74 even though it was supposed to return -1. Fixed this. The
75 affected file is lib/silccore/silcpacket.c.
77 * Do not replace the config files in /etc/silc (in make install)
78 if they already exist. Affected file ./Makefile.am.
80 * Do not send re-key packets immediately but through packet queue.
81 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
83 * Changed silc_net_check_host_by_sock to return FALSE if the
84 IP/DNS could not be resolved. Though, it returns the IP address
85 now even if it could not resolve it (but returns also FALSE).
86 Affected file lib/silcutil/silcnet.[ch].
88 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Added silc_pkcs_decode_identifier to decode the public key's
91 identifier. Affected file lib/silccrypt/silpkcs.[ch].
92 Added also silc_pkcs_free_identifier. Added also new context
93 SilcPublicKeyIdentifier.
95 * Added -S option to the silc client. It is used to dump the
96 contents of the specified public key file.
98 * Changed the PKCS api to return the public key length when
99 setting the public key.
101 * Fixed a fatal bug in the public and private key file loading.
102 Affected file lib/silccrypt/silcpkcs.c.
104 * Execute the packet parsing for client with zero (0) timeout
105 if the protocol is active. Affected file silcd/server.c.
107 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Made the key generation options to the silcd program. Added
110 -C option, equivalent to client's option.
112 * Added new [ServerKeys] config section to the server. It
113 configures the server's public and private key.
115 * Defined generic Public Key Payload into the protocol
116 specification to send specific type of public keys and
119 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
120 public key or certificate.
122 * Implemented the GETKEY command to the server and to the
123 client library and on user interface.
125 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Made preliminary `make install' work.
129 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Added SilcServerRekey context into silcd/idlist.h.
133 * Added the PFS support as defined in the specification to the
134 SKE protocol. Affected files lib/silcske/*.c.
136 * Added `ske_group' field to the SilcServerRekey context to hold
137 the number of the SKE group that is used with PFS in re-key.
138 Affected file silcd/idlist.h.
140 * Added PFS re-key support to the server. Affected file is
143 * Added silc_protocol_cancel to cancel execution of the next
144 state of the protocol. Affected file is
145 lib/silccore/silcprotocol.[ch].
147 * Added the re-key support with and without PFS to the client
148 library. Re-key is performed once in an hour, by default.
150 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
151 Added silc_client_rekey_callback and silc_client_rekey_final.
152 Affected files are lib/silcclient/protocol.[ch] and
153 lib/silcclient/client.[ch].
155 * Removed the `hmac_key' and `hmac_key_len' fields from the
156 SilcClientConnection structure; not needed. Affected file is
157 lib/silcclient/client.h.
161 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
163 * Do not ask whether user wants to use the negotiated private key
164 for private messages, just use it. Affected file is
165 silc/local_command.c.
167 * Added `send_enc_key' and `enc_key_len' fields to the
168 SilcIDListData structure since they are needed in the re-key
169 phase. Affected file is silcd/idlist.[ch].
171 * Implemented the simple re-key protocol into the server.
172 Affected files silcd/server.c and silcd/protocol.[ch]. The
173 re-key will be performed once in an hour, by default.
175 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
176 Added silc_server_rekey, silc_server_rekey_callback and
177 silc_server_rekey_final.
179 * Removed Tunneled flag from the protocol. Updated the code
180 and the specifications.
182 * Adde `pfs' field to the SilcIDListData to indicate whether
183 the PFS is to be performed in the re-key. Affected file is
186 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
189 int64 of at least the xintXX size. If void * is less that 4
190 bytes uint32 * will be used. Defined bool as boolean.
192 * Changed _ALL_ unsigned long and unsigned int to uint32,
193 unsgined short to uint16 in the source tree.
195 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
196 not handle clients that has entry->data.registered == FALSE.
197 They are not in the network anymore. Affected file is
200 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Implemented the sending of the SERVER_SIGNOFF notify in the
203 server. Affected file is silcd/server.c.
205 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
206 Added also silc_notify_payload_encode_args into the
207 lib/silccore/silcnotify.[ch].
209 * Implemented ther SERVER_SIGNOFF notify handling in the server.
210 Affected file silcd/packet_receive.c.
212 * Implemented the SERVER_SIGNOFF notify handling in the client
213 library. Affected file lib/silcclient/client_notify.c. Also,
214 implemnted the printing of the SERVER_SIGNOFF info to the
215 application. Affected file silc/client_ops.c.
217 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
218 if the deleting was successful. Affected file silcd/idlist.[ch].
220 * Added support for public key authentication in the connection
221 authentication protocol in the client library. Affected file
222 lib/silcclient/protocol.c.
224 * Changed the server's silc_idlist_get_clients_by_* interface
225 to support already allocated array so that new entries may be
226 added to pre-allocated array. Affected file silcd/idlist.[ch].
227 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
230 * All command reply functions in the server now calls the
231 pending command callback even if error occured. This way the
232 error will be delivered to the client as well. Affected files
233 silcd/command.c and silcd/command_reply.c.
235 * Fixed INFO command to return local server's info if no server
236 was provided. Affected file lib/silcclient/command.c.
238 * Removed RESTART command for good. Updated the code and the
241 * Rewrote parts of the task system. It is a bit simpler now.
242 Removed unsued task priorities. The affected files are
243 lib/silcutil/silctask.[ch].
245 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Moved the USERS printing from the library to the application.
248 Affected files lib/silcclient/command.c and silc/client_ops.c.
250 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added channel key re-key support. The re-key is perfomed
255 only by the router and is done once in an hour. Added `rekey'
256 field to the SilcChannelEntry in the server. Affected files
257 silcd/server.c and silcd/idlist.h.
259 * Added silc_task_unregister_by_context into the file
260 lib/silcutil/silctask.[ch].
262 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Added SILC_UMODE_GONE mode to indicate when the client is not
265 present in the SILC network. Added also support to the local
266 command AWAY that will set this mode. Added support of showing
267 "xxx is gone" in WHOIS command. The USERS command shows the
270 * Fixed setting server and router operator privileges in the
271 server's UMODE command. Affected file silcd/command.c.
273 * Merged the SKE KE1 and KE2 payloads into one payload. The
274 new KE payload is equivalent to the old KE2 payload.
276 Cleaned up the SKE Start Payload parsing. It now uses the
277 simple buffer unformatting to do the parsing. A lot faster
280 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
281 to the SKE that is used to indicate whether both of the SKE
282 parties should perform authentication. By default only the
283 responder performs authentication. By setting this flag also
284 the initiator must do authentication. By default it is unset
285 since in normal SKE case, client to server connection, only
286 the responder should do authentication. When doing SKE between
287 two clients both should perform authentication. Updated the
288 code and the protocol specs.
290 * A little fix to IDENTIFY command in the server. Search the
291 client first by hash not nickname. Affected file is
294 * Fixed the silc_client_close_connection to support closing
295 the client to client connections wihtout deleting too much
296 data. Affected file lib/silcclient/client.c.
298 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
299 are received if protocol used to be active but is not anymore
300 the application would crash due to NULL pointer dereference.
301 Affected files silcd/server.c and lib/silcclient/client.c.
303 * Added `hash' field to the SilcClientConnection to include
304 the hash function negotiated in the SKE protocol.
306 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
307 to set the channel founder authentication data. A client can
308 claim the founder rights later by providing the authentication
309 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
310 This way the channel founder can regain the channel founder
311 privileges even it is left the channel. This works only on
312 local server and the client must be connected to the same
313 server to be able to regain the founder rights. Updated the
314 protocol specs accordingly.
316 Added support to the CMODE command in the client to set the
317 founder auth data. Read the README to see how to set it.
319 Added support to the CUMODE command to claim the founder
320 rights. Read the README to see how to do it.
322 Added support for the founder authentication to the Channel
323 Entry in the server. Affected file silcd/idlist.h.
325 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
326 server's CMODE command. Affected file silcd/command.c.
328 * Added the following new functions into lib/silccore/silcauth.[ch]:
329 silc_auth_get_method and silc_auth_get_data.
331 * The server now saves the remote hosts public key to the
332 SilcIDListData pointer. Affected file silcd/protocol.c.
334 * The normal server now does not remove the channel entry from
335 the cache if the founder authentication data is set. It used
336 to remove it if the founder was the last one on the channel on
337 the server and left the channel. The auth data is saved and
338 if the channel is re-joined later the old entry is used with
339 the old auth data. Affected files silcd/command_reply.c and
342 * Removed the `pkcs' field from the SilcIDListData structure
343 in the server; it is not used. Affected file silcd/idlist.h.
345 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
347 * Fixed packet processing on slow links. Partial packets were
348 never re-processed because the incoming data buffer was cleared
349 by the application. Application must not directly clear the
350 sock->inbuf, the packet processing routines handle it. Fixed
351 this in client library and in server.
353 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
355 * Fixed the WHOIS and IDENTIFY send reply function to really
356 check whether to send list or just one entry. Affected file
359 * Cleaned up the LEAVE command's channel key distribution. The
360 affected file silcd/command.c.
362 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
363 can enforce the channel mode as well. In that case the ID
364 includes the ID of the server. The code now enforces the
365 mode change if the router have different mode than the server.
367 * The notify client operation with CMODE_CHANGE notify can now
368 return NULL client_entry pointer if the CMODE was not changed
369 by client. Application must check for this.
371 * Added <Server ID> argument to INFO command to support server
372 info fetching by Server ID.
374 * Added silc_server_announce_get_channel_users to get assembled
375 packets of channel users of the specified channel. Affected
376 file silcd/server.[ch].
378 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
379 was freed underneath the ID Cache.
381 * Re-announce clients when the server received CHANNEL_CHANGE
382 notify from the router. Affected file silcd/packet_send.c.
384 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
387 crashed since it did not handle the fact that there is no cipher
388 called "3" and didn't check the error condition. Now fixed.
390 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
391 flag. It can be used to send message requests.
393 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Implemented the RESTART command in the client.
397 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
398 notice type messages. Added notice printing to the user
401 * The channel keys are not re-generated if the channel's mode
402 is PRIVKEY, ie private key on the channel exists. Affected
403 files silcd/server.c and silcd/command.c.
405 * Fixed a little bug in channel message delivery when channel
406 private keys are set in the server. Affected file is
409 * Changed the setting on channel->on_channel = TRUE from the
410 silc_client_save_channel_key to the JOIN command reply. The
411 key payload is not received if the private channel key is set.
412 Affected file lib/silcclient/command_reply.c and the
413 lib/silcclient/client_channel.c.
415 * When the CMODE_CHANGE notify is sent and the channel private
416 key mode is removed the channel key must be re-generated in
417 other cells as well. Added this support for the router in the
418 silcd/packet_receive.c.
420 * Added new local command NOTICE to send notice message on
421 channel. Affected file silc/local_command.[ch].
423 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Added new local command ME to the client. It is used to send
426 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
427 some action. Affected file silc/local_command.[ch].
429 * Changed channel_message and private_message client operations
430 to deliver the message flags to the application. Added also
431 the `flags' arguments to the silc_client_send_channel_message
432 and silc_client_send_private_message functions. Affected file
435 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Redefined the Private Message Payload to support private message
438 keys and to support the new private message flags. Updated
439 the protocol specs. Flags makes it possible to have for example
442 * Added new type SilcPrivateMessagePayload and defined an API
443 for it in the lib/silcclient/silcprivate.[ch].
445 * Tested private message private keys successfully. Tested the
446 private message key set, unset and list commands with the new
449 * Redefined the Channel Message Payload to include the channel
450 message flags (equal with private message flags) to support
451 for example CTCP style messages.
453 * Defined some of the message (for channel and private message)
454 flags. Updated the protocol specs and added the flags to the
455 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
457 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Added SilcKeyAgreementStatus type to the key agreement routines
460 to indicate the current status and error if one occured.
461 The status types are defined in the lib/silcclient/silcapi.h.
463 * Added new local command KEY that is used to set and unset private
464 keys for channels, set and unset private keys for private messages
465 with remote clients and to send key agreement requests and
466 negotiate the key agreement protocol with remote client. The
467 key agreement is supported only to negotiate private message keys,
468 it currently cannot be used to negotiate private keys for channels,
469 as it is not convenient for that purpose.
471 * Fixed a minor pending callback setting bug in the function
472 silc_client_get_client_by_id_resolve, now the function works.
473 Affected file lib/silcclient/idlist.c.
475 * Added function silc_net_get_local_port to get local bound
476 port by socket. Added to lib/silcutil/silcnet.[ch].
478 * Added `sockets' and `sockets_count' fields to the SilcClient
479 object. They hold the sockets of the listenning sockets in
480 the client. Listenning sockets may be for example the key
481 agreement server. Affected file lib/silcclient/client.[ch].
482 Added functions the silc_client_add_socket and the
483 silc_client_del_socket. They are exported to the application
486 * Added ~./silc/clientkeys to support other client's public keys.
488 * Renamed verify_server_key client operation to verify_public_key
489 and added one argument to indicate the type of the connection
490 (server, client etc.).
492 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Added silc_server_connection_auth_request to handle the
495 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
496 silcd/packet_receive.[ch].
498 * Added silc_server_send_connection_auth_request into the
499 silcd/packet_send.c to send the connection auth request packet.
501 * Cleaned up the silcd/protocol.c a bit and fixed some memory
504 * Fixed the public key authentication in responder side in the
505 server. The `auth_data' pointer includes the SilcPublicKey
506 not the path to the public key. Affected file silcd/protocol.c.
508 * Implemented the public key authentication in the initiator side
509 in the server. Affected file silcd/protocol.c.
511 * Removed the [RedirectClient] config section from the server
512 configuration. Is not needed and I don't want to implement it.
514 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Cleaned up the CMODE command in the server. It now works
517 correctly and supports all the modes defined in the protocol.
518 Affected file is silcd/command.c.
520 * Added `hmac_name' field to the SilcChannelEntry in the server
521 to hold the default HMAC of the channel. It can be set when
522 creating the channel (with JOIN command). Affected files
525 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
526 type to indicate the change of the current cipher and hmac
527 on the channel. Client can safely ignore the <cipher> argument
528 (if it chooses to do so) since the CHANNEL_KEY packet will
529 force the channel key change anyway. The <hmac> argument is
530 important since the client is responsible of setting the new
531 HMAC and the hmac key into use.
533 * Fixed the CMODE command in the client library as well.
535 * Tested CMODE command in router environment successfully.
537 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Show the version of the remote client (or server) when connecting
540 to the server. It is logged to the log file. Affected file
543 * Fixed the KILLED notify handling in the client library. The
544 client must be removed from all channels when receiving the
547 Also, do not remove the client entry when giving the KILL
548 command but when the KILLED notify is received.
550 * Removed silc_idlist_find_client_by_nickname from the server.
551 Not needed anymore. Affected files silcd/idlist.[ch].
553 * Implemented the CHANNEL_CHANGE notify type handling to the
554 server. Affected file silcd/server.c.
558 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
560 * Added silc_server_send_notify_invite to send the INVITE
561 notify between routers.
563 * Implemented the INVITE command correctly to the server.
565 * Implemented the INVITE notify type handling in the server.
567 * Implemented the INVITE command to the client library and on the
570 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Added function silc_server_get_client_resolve to find the
573 client entry by ID from all ID lists and then resolve it
574 (using WHOIS) if it cannot be found. Affected file is
577 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Implemented the BAN command to the client library.
581 * The JOIN command in the server now checks the invite list
584 * Changed the silc_command_reply_payload_encode_va and the
585 silc_command_payload_encode_va to support that if argument is
586 NULL it ignores and checks the next argument. Affected file
587 lib/silccore/silccommand.c.
589 * Added silc_server_send_notify_ban to send the BAN notify
590 type between routers.
592 * Chaned the silc_notify_payload_encode to support that if
593 argument is NULL it ignores and checks the next argument.
594 Affected file lib/silccore/silcnotify.c.
596 * Tested ban lists in router environment successfully.
598 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Implemented BAN command to the server, in silcd/command.[ch].
602 * Removed the BAN and INVITE_LIST modes from the CMODE command
605 * Added function silc_string_match to regex match two strings.
606 Affected files lib/silcutil/silcutil.[ch].
608 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Redefined parts of the SilcChannelEntry in the server to support
611 the new ban and invite lists.
613 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Redefined the INVITE command. The same command can be used to
616 invite individuals to the channel but also to manage the invite
617 list of the channel (to add to and remove from the invite list).
618 Updated the protocol specs.
620 * Added new command SILC_COMMAND_BAN that can be used to manage
621 the ban list of the channel. Updated the protocol specs.
623 * Removed the channel modes: the SILC_CMODE_BAN and the
624 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
625 in the CMODE command. The equivalent features are now available
626 using INVITE and BAN commands. Updated the protocol specs.
628 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
629 in the network about change in the current ban list. The notify
630 type is not used by the client.
632 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
633 support the invite lists.
635 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
637 * Added new function silc_string_regexify that converts string
638 including wildcard characters into regex string that can
639 be used by the GNU regex library. Added into the file
640 lib/silcutil/silcutil.[ch].
642 Added silc_string_regex_combine to combine to regex strings
643 into one so that they can be used as one regex string by
644 the GNU regex library. Added into the file
645 lib/silcutil/silcutil.[ch].
647 Added silc_string_regex_match to match two strings. It returns
648 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
650 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Imported GNU regex to the soruce tree into lib/contrib.
653 Fixed some compiler warning from the regex.c.
655 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Fixed MOTD command in the server to work in router environment.
659 * Fixed the MOTD command in the client library to support
660 the server argument in the command.
662 * Added `nickname_len' argument to the silc_idlist_add_client
663 in the server, as the `nickname' argument may be binary data
666 * Added silc_idlist_get_channels to return all channels from
669 * Implemented LIST command to the server. Affected file is
672 * Implemented the LIST command to the client library and on the
675 * Added [<user count>] argument to the LIST command reply.
676 With private channels the user count is not shown.
678 * Updated TODO and README.
680 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * The client entry's data.registered must be TRUE even with
683 global client entry on global client list. The data.registered
684 is used to check whether the client is anymore in the network,
685 for example with WHOWAS command so it must be valid.
687 * Fixed the WHOWAS command in the server. It now actually works
688 in router environment. Added function into silcd/command_reply.c
689 silc_server_command_reply_whowas_save.
691 * Added silc_idlist_purge function to the silcd/idlist.c
692 to periodically purge the ID Cache.
694 * Fixed INFO command in the server. It works now in router
695 environment. Added <server name> argument to the INFO command
696 reply. Updated the protocol specs.
698 * Fixed minor bug in silc_idcache_purge to not purge if the
699 expire value is zero.
701 * Fixed various bugs in WHOIS and IDENTIFY command handling as
702 they were buggy because of the WHOWAS information.
704 * Fixed local command MSG to handle the async resolving of
705 the remote client properly. It used to fail the first MSG.
706 Affected file silc/local_command.c.
708 * Added `data_len' field to SilcIDCache context.
710 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Update TODO. Todo in commands in the server.
714 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
717 used by routers as broadcast packet to inform other routers
718 about the changed user mode.
720 Implemented the notify handling in the server. Affected file is
721 silcd/packet_receive.c. Added the function
722 silc_server_send_notify_umode to the silcd/packet_send.[ch].
724 * Added new generic Channel Payload and deprecated the New Channel
725 Payload. The New Channel Payload is now the generic Channel
728 * Added new argument `mode' to the silc_server_send_new_channel
729 as it is required in the Channel Payload now.
731 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
732 and created a new and real SilChannelPayload to represent the
733 new generic Channel Payload. Implemented the encode/decode
734 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
736 * Added silc_server_get_client_channel_list to return the list
737 of channels the client has joined for WHOIS command reply.
738 Affected file silcd/server.[ch].
740 * Implemented the channel list sending in the WHOIS command reply
741 in server and in the client.
743 Implemented the channel list displaying on the user interface
744 as well. Affected file silc/client_ops.c.
746 * Added silc_channel_payload_parse_list to parse list of Channel
747 Payloads. It returns SilcDList list of SilcChannelPayloads.
748 Client for example can use this function to parse the list of
749 channels it receives in the WHOIS command reply. The caller
750 must free the list by calling silc_channel_payload_list_free.
751 Affected files lib/silccore/silcchannel.[ch].
753 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added one new argument <user mode> to the WHOIS command reply
756 to return the mode of the user in SILC. Updated the protocol
759 Implemented it to the server and client.
761 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * Fixed the mode printing on the user interface on joining.
764 Affected file silc/client_ops.c.
766 * Implemented the UMODE command and user modes in general to the
767 client library and to the user interface.
769 * Implemented the UMODE command to the server.
771 * The server now sends UNKNOWN_COMMAND error status if client sends
772 unknown command. Affected file silcd/command.c.
774 * All server commands now handle the command identifier the right
775 way when sending the command reply to the client. The client can
776 use to identify the command replies with the identifier.
778 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added silc_server_get_client_route to resolve the route to
781 the client indicated by the client ID. Affected file is
784 * Added silc_server_relay_packet as general function to relay
785 packet to arbitrary destination. This deprecates functions
786 like _send_private_message_key, _relay_notify etc. Affected
787 file is silcd/packet_send.[ch].
789 Removed silc_server_send_key_agreement,
790 silc_server_send_private_message_key and
791 silc_server_packet_relay_notify functions from the file
792 silcd/packet_send.[ch].
796 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
797 server. Affected file silcd/packet_receive.[ch].
799 * Implemented the KILL command to the client. Implemented the
800 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
801 Affected files lib/silcclient/command[_reply].c and
802 lib/silcclient/client_notify.c. Implemented the KILL notify
803 printing in the user inteface.
805 * Fixed a lot silc_parse_nick memory leaks from the client
806 library in the file lib/silcclient/command.c.
808 * Changed the silc_server_send_notify_on_channels's `sender'
809 argument from SilcSocketConnection to SilcClientEntry to
810 check the sender as entry and not as connection object and not
811 to send to the client provided as argument. The affected file
812 is silcd/packet_send.[ch].
814 * The notify packets that are destined directly to the client used
815 to not to be processed by the server. Now changed that and the
816 server processes all notify packets. After relaying the packet
817 to the client the notify packet is processed in the server.
819 * The silc_server_free_client_data now checks whether there is
820 pending outgoing traffic for the client and purges the data to
821 the network before removing the client entry.
823 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
826 an client is killed from the SILC Network. Updated the protocol
829 Added new function silc_server_send_notify_killed to the
830 silcd/packet_send.[ch].
832 * Added function silc_server_packet_relay_notify to relay notify
833 packets that are destined directly to a client. In this case
834 the server does not process the notify packets but merely relays
835 it to the client. Affected file silcd/packet_send.[ch].
837 Added also silc_server_packet_process_relay_notify to check
838 whereto relay the notify. Affected file is
839 silcd/packet_receive.[ch].
841 * Implemented the KILL command to the server.
845 * Added the backup schema desgined last fall to the protocol
846 specs for everyone to see. The specification is in the
847 *-spec-xx.txt draft and the packet type definitions for the
848 backup routers is in *-pp-xx.txt draft. Thusly, added also
849 new packet type SILC_PACKET_CELL_ROUTERS.
851 * A big security problem in the implementation discovered. The
852 signoff of an client did not cause new channel key generation
853 which it of course should've done. The channel keys must be
854 always re-generated when client leaves (or signoffs) the channel.
855 The silc_server_remove_from_channels funtion now handles
856 the channel key re-generation.
858 * Added `sender' argument to the silc_server_send_notify_on_channels
859 to not to send the client provided as argument. Affected file
860 silcd/packet_send.[ch].
862 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Implemented OPER and SILCOPER commands into the server and
867 * Added silc_auth_verify and silc_auth_verify_data to verify
868 the authentication directly from the authentication payload.
869 It supports verifying both passphrase and public key based
870 authentication. Affected file lib/silccore/silcauth.[ch].
872 * Added `hash' field to the SilcIDListData structure. It is the
873 hash negotiated in the SKE protocol. Affected file is
876 * Slight redesigning of the SilcAuthPayload handling routines.
877 Do not send SilcPKCS but SilcPublicKey as argument.
879 * Implemented the public key authentication support to the
880 serverconfig. The public key is loaded from the provided path
881 and saved as authentication data to void * pointer. Thus,
882 changed the unsigned char *auth_data to void *auth_data;
884 * Fixed SHUTDOWN command to send the reply before the server
885 is shutdown. :) Affected file silcd/command.c.
887 * Fixed fatal bug in CONNECT command. The hostname was invalid
888 memory and server crashed. Affected file silcd/command.c.
890 * Fixed fatal bug in CLOSE command. The server_entry became
891 invalid but was referenced later in the command. Affected file
894 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Fixed fatal bug in failure packet handling. Server ignored
897 the failure and thus crashed when it came.
901 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
904 that the command may be executed only once in (about) 2 seconds.
905 The old SILC_CF_LAG flag is same but allows command bursts up
906 to five before limiting.
908 Added the support for CF_LAG and CF_LAG_STRICT flags to the
909 server code. Various commands now includes the CF_LAG_STRICT
910 flag to disallow any kind of miss-use of the command.
912 * Fixed the silc_buffer_unformat to not to allocate any data
913 if the length of the data is zero. It used to allocate the
914 length + 1. Affected file lib/silcutil/silcbuffmt.c.
916 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Changed the format of AdminConnection configuration section
919 in the server. Added username of the admin to the format.
920 Affected files silcd/serverconfig.[ch].
922 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
923 to return admin configuration data by host, username and/or
926 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Implemented WHOWAS command to the server. Added the functions:
930 silc_server_command_whowas_parse,
931 silc_server_command_whowas_send_reply,
932 silc_server_command_whowas_from_client and
933 silc_server_command_whowas_from_server
935 * Added <Client ID> argument to the WHOWAS command reply. Updated
936 the protocol specs accordingly.
938 * Implemented WHOWAS command and command_reply to the client
941 Implemented the WHOWAS printing on the user interface.
943 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added new argument to the WHOWAS command reply, the real name.
946 It is an optional argument. Updated the protocol specs.
948 * Added SilcIDCacheDestructor callback that is registered when
949 the SilcIDCache is allocated. The callback is called when
950 an cache entry in the ID Cache expires, or is purged from the
951 cache. Added into lib/silccore/idcache.[ch].
953 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
954 to destruct the client entries when the cache entry expires.
955 Other ID Cache's in server and in the client library ignores
958 * If the ID Cache entry's `expire' field is zero then the entry
959 never expires. Added boolean `expire' argument to the
960 silc_idcache_add function in the lib/silccore/idcache.[ch].
961 If it is TRUE the default expiry value is used.
963 * Added silc_server_free_client_data_timeout that is registered
964 when client disconnects. By default for 5 minutes we preserve
965 the client entry for history - for WHOWAS command.
967 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added support to the server to enforce that commands are not
970 executed more than once in 2 seconds. If server receives
971 commands from client more frequently, timeout is registered
972 to process the commands. Affected file silcd/command.c.
973 Added new function silc_server_command_process_timeout.
975 * Changed NICK_NOTIFY handling in client library to check that
976 if the client's nickname was changed, so there is no need to
977 resolve anything from the server.
979 * Removed error printing from the WHOIS and IDENTIFY commands.
980 If error occurs then it is ignored silently in the client library.
981 The application, however, may map the received error to
982 human readable error string. The application currently maps
983 the NO_SUCH_NICKNAME error to string.
985 * Made the command status message public to the application. Moved
986 them from lib/silcclient/command_reply.c to
987 lib/silcclient/command_reply.h. The application can map the
988 received command status to the string with the
989 silc_client_command_status_message function.
991 * Added check to the server to check that client's ID is same
992 as the Source ID in the packet the client sent. They must
995 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Added dist-bzip hook to the Makefile.am to make bzip2
998 compressed distributions.
1000 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Server now enforces the maximum length for the nickname and
1003 the channel as protocol specification dictates. 128 bytes for
1004 nickname and 256 bytes for channel name.
1006 * Moved the WHOIS printing to the application. The client libary
1007 does not print out the WHOIS information anymore, the application
1008 must do it. Renamed silc_client_command_reply_whois_print to
1009 the silc_client_command_reply_whois_save.
1011 The client's idle time is also sent to the application now, and
1012 the idle is shown on screen.
1014 * Added silc_client_command_reply_identify_save to save the
1015 received IDENTIFY entries.
1017 * Do not check for channel private keys in message sending and
1018 reception if the channel does not have the PRIVKEY mode set.
1019 Affected file lib/silclient/client_channel.c.
1021 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1024 just surfaced after chaning the JOIN procedure.
1026 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Added silc_client_get_clients_by_list to get client entries
1029 from Client ID list, that is returned for example by JOIN
1030 and USERS command replies. The application should use this
1031 function for example when JOIN command reply is received to
1032 resolve the clients already on the channel (library does not
1033 do that anymore as USERS command reply is not used in the JOIN
1034 procedure anymore). Affected files lib/silcclient/silcapi.h and
1035 lib/silcclient/idlist.c.
1037 * JOIN command reply and USERS command reply returns now SilcBuffer
1038 pointers instead of unsigned char pointers when returning
1039 the client list and mode list.
1041 * Added <Client ID> argument to the JOIN command reply, mainly
1042 for the server to identify for which client the command was
1043 originally sent. Updated protocol specs accordingly.
1045 * Added SilcDlist private_key pointer to the SilcChannelEntry
1046 in the client to support the channel private keys. Affected
1047 file is lib/silcclient/idlist.h.
1049 * Added SilcChannelPrivateKey argument to the function
1050 silc_client_send_channel_message so that application can choose
1051 to use specific private ke if it wants to. If it is not provided,
1052 the normal channel key is used, unless private keys are set.
1053 In this case the first (key that was added first) is used
1054 as the encryption key.
1056 * Implemented the support for channel private key handling.
1057 Implemented the following functions:
1059 silc_client_add_channel_private_key,
1060 silc_client_del_channel_private_keys,
1061 silc_client_del_channel_private_key,
1062 silc_client_list_channel_private_keys and
1063 silc_client_free_channel_private_keys
1065 Affected file lib/silcclient/client_channel.c.
1067 * Added the support for the private keys in the channel message
1068 sending and encryption and in the message reception and
1069 decryption. Affected funtions are
1070 silc_client_send_channel_message and silc_client_channel_message.
1072 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Added SKE's key verify callback to the client library's
1075 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1077 * Removed the statement that server (or router) must send USERS
1078 command reply when joining to the channel so that the client
1079 knows who are on the channel. Instead, the client list and
1080 client's mode list is now sent in the JOIN command reply to the
1081 client who joined channel. This is better solution.
1083 * Added function silc_server_get_users_on_channel and function
1084 silc_server_save_users_on_channel to the silcd/server.[ch].
1086 * Removed function silc_server_command_send_users from the
1089 * Do not show topic on the client library anymore. The topic is
1090 sent in the command reply notify to the application and the
1091 application must show the topic now.
1093 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added client searching by nickname hash into the IDENTIFY and
1096 WHOIS commands in the server as they were clearly missing from
1097 them. Affected file is silcd/command.c.
1099 * Fixed a bug in private message receiving in the client library.
1100 The remote ID was freed and it wasn't supposed, now it is
1103 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Minor fix to the channel payload; allocate the data area, as it
1106 needs to be of specific length.
1108 * If the key agreement port is zero then the operating
1109 system will define the bound port. Affected files are
1110 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1112 * Added new function silc_channel_payload_decrypt into the file
1113 lib/silccore/silcchannel.[ch].
1115 * Moved the channel message etc, check from silc_packet_decrypt
1116 to applications. The library calls now a generic
1117 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1118 when the packet is either normal or special. This was done to
1119 allow more wide range of checking that was not allowed when
1120 the code was in library. Now applications can do virtually any
1121 checks to the packet and return to the library the decision how
1122 the packet should be processed. Affected files are
1123 lib/silccore/silcpacket.[ch].
1125 Added silc_server_packet_decrypt_check to the server and
1126 silc_client_packet_decrypt_check to the client library.
1128 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1129 to send with specified source and destination information.
1131 * Channel message delivery between routers was broken after the
1132 channel key distribution was fixed earlier. The channel key
1133 was used be to distributed to other routers as well which is not
1134 allowed by the protocol. Now this is fixed and channel keys
1135 really are cell specific and the channel message delivery between
1136 routers comply with the protocol specification.
1138 * Fixed various commands in server to check also the global list
1139 for the channel entry and not just the local list. The affected
1140 file silcd/command.c.
1142 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Added assert()s to buffer formatting and unformatting routines
1145 to assert (if --enable-debug) when error occurs. Affected
1146 file: lib/silcutil/silcbuffmt.c.
1148 * Changed to auto-reconnect to check whether the remote host is
1149 router and register the re-connect timeout if it is. It used
1150 to check that whether we are normal server, but router must do
1151 auto-reconnect with another router as well. Affected file
1154 * Removed the [<key len>] option from CMODE command as the cipher
1155 name decides the key length, nowadays. See the defined ciphers
1156 from the protocol specification.
1158 * Added [<hmac>] option to the CMODE command to define the HMAC
1159 for the channel. Added SILC_CMODE_HMAC channel mode.
1161 * Added [<hmac>] option for the JOIN command so that user can
1162 select which HMAC is used to compute the MACs of the channel
1165 * Added Hmac field to the Channel Message Payload. The integrity
1166 of plaintext channel messages are now protected by computing
1167 MAC of the message and attaching the MAC to the payload. The
1168 MAC is encrypted. Now, it is clear that this causes some
1169 overhead to the size of the packet but rationale for this is that
1170 now the receiver can verify whether the channel message decrypted
1171 correctly and also when private keys are set for the channel the
1172 receiver can decrypt the packet with several keys and check from
1173 the MAC which key decrypted the message correctly.
1175 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1176 lib/silccrypt/silccipher.[ch].
1178 * Added silc_hash_len to return the digest length into the
1179 lib/silcrypt/silchash.[ch].
1181 * Rewrote parts of Silc Channel Payload interface in the
1182 lib/silccore/silcchannel.[ch]. The encode function now also
1183 encrypts the packet and parse function decrypts it.
1185 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Fixed a minor formatting bug in the SKE's key material processing.
1188 It actually might have processed the keys wrong way resulting
1191 * Redefined the mandatory HMAC algorithms and added new algorithms.
1192 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1193 and hmac-md5 truncated to 96 bits. The mandatory is now
1194 hmac-sha1-96. Rest are optional (including the one that used
1195 to be mandatory). Rationale for this is that the truncated HMAC
1196 length is sufficient from security point of view and can actually
1197 make the attack against the HMAC harder. Also, the truncated
1198 HMAC causes less overhead to the packets. See the RFC2104 for
1201 * Added new [hmac] configuration section. The SKE used to use
1202 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1203 is of course wrong. The official names that must be proposed in
1204 the SKE are the ones defined in the protocol specification
1205 (hmac-sha1-96 for example). The user can configure any hmac
1206 using any hash function configured in the [hash] section. At
1207 least, the mandatory must be configured.
1209 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1211 * Added HMAC list to the SKE proposal list. It has now both
1212 hash algorithm list and HMAC list. This makes the protocol
1213 incompatible with previous versions. The SKE now seems to work
1214 the way it is supposed to work, for the first time actually.
1216 * Defined plain Hash algorithms to the protocol specification.
1219 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Implemented support for key agreement packets into the server.
1222 Added functions silc_server_key_agreement and
1223 silc_server_send_key_agreement. Other than these functions,
1224 server has nothing to do with this packet.
1226 * Added support for private message key packets into the server.
1227 Added functions silc_server_private_message_key and
1228 silc_server_send_private_message_key.
1232 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1233 called in the protocol's final callback instead in the END
1234 protocol state. This makes a little more sense and in the same
1235 time in client we can use the same protocol routines for normal
1236 key exchange and to key agreement packet handling as well.
1238 * Added to both client's and server's KE protocol context the
1239 SilcSKEKeyMaterial pointer to save the key material. We will
1240 bring the key material to the protocol's final callback by doing
1241 this. The final callback must free the key material.
1243 * Added SKE's packet_send callback into client's KE protocol
1244 context so that the caller can choose what packet sending function
1245 is used. This way we can use different packet sending when
1246 doing normal SKE when doing key agreement packet handling (in
1247 the key agreement packet handling we do not want to encrypt
1250 * Implemented the responder side of the key agreement routines
1251 in the client. The client can now bind to specified port and
1252 accept incoming key negotiation. The key material is passed
1253 to the application after the protocol is over.
1255 * Implemented the processing of incoming Key Agreement packet
1256 in the client. Added function silc_client_key_agreement to
1259 * Implemented the intiator side of the key agreement routines
1260 in the client. The client can now initiate key agreement with
1261 another remote client. The key material is passed to the
1262 application after the protocol is over.
1264 * Created client_keyagr.c to include all the key agreement
1267 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1268 SILC_TASK_CALLBACK except that it is not static.
1270 * Created client_notify.c and moved the Notify packet handling
1271 from the client.[ch] into that file.
1273 * Created client_prvmsg.c and moved all private message and
1274 private message key routines from the client.[ch] into that file.
1276 * Create client_channel.c and moved all channel message and
1277 channel private key routines from the client.[ch] into that file.
1279 * Changed silc_client_get_client_by_id_resolve to resolve with
1280 WHOIS command instead of IDENTIFY command, in the file
1281 lib/silclient/idlist.c.
1283 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Implemented the SKE's responder side to the Client library.
1287 * When FAILURE is received to the protocol do not trust it
1288 blindly. Register a timeout to wait whether the remote closes
1289 the connection as it should do it, only after that process the
1290 actual failure. This was changed to both client and server.
1292 * Added client_internal.h to include some of the structures
1293 there instead of client.h in lib/silcclient/.
1295 * Added function silc_task_unregister_by_callback to unregister
1296 timeouts by the callback function.
1298 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Some "Incomplete WHOIS info" errors has been appearing on the
1301 log files. Took away the entry->userinfo check from WHOIS
1302 reply sending. The entry->userinfo is now " " if client did not
1303 provide one. I thought this was fixed earlier but something
1304 is wrong still. Let's see if the error still appears.
1306 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Fixed a minor bug in the login when the channel key is
1309 re-generated in the server. It used to generate the key in
1310 wrong order and thus caused problems in the channel traffic.
1312 * Fixed a minor bug in channel key distsribution after
1313 KICK command. The key was not sent to the router even though
1316 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Added silc_ske_process_key_material_data as generic routine
1319 to process any key material as the SILC protocol dictates. The
1320 function is used by the actual SKE library but can be used by
1321 applications as well. This relates to the private message keys
1322 and the channel private keys since they must be processed the
1323 same way the normal SILC session keys. The protocol dictates
1324 this. Affected files: lib/silcske/silcske.[ch].
1326 Added also silc_ske_free_key_material to free the
1327 SilcSKEKeyMaterial structure.
1329 * Defined silc_cipher_set_key function to set the key for
1330 cipher without using the object's method function. The affected
1331 files: lib/silccrypt/silccipher.[ch].
1333 * Implemented silc silc_client_add_private_message_key,
1334 silc_client_add_private_message_key_ske,
1335 silc_client_del_private_message_key,
1336 silc_client_list_private_message_keys and
1337 silc_client_free_private_message_keys functions in the
1340 Added functions silc_client_send_private_message_key to send
1341 the Private Message Key payload and silc_client_private_message_key
1342 to handle incoming Private Message Key payload.
1344 * Added Cipher field to the Private Message Key payload to set
1345 the cipher to be used. If ignored, the default cipher defined
1346 in the SILC protocol (aes-256-cbc) is used.
1348 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * Removed lib/silcclient/ops.h file.
1352 Redefined parts of the SILC Client Library API. Created new
1353 file silcapi.h that deprecates the ops.h file and defines the
1354 published Client Library API. Defined also private message key
1355 API and channel private key API into the file.
1357 This is the file that the application must include from the
1358 SILC Client Library. Other files need not be included by
1359 the application anymore.
1361 * Added new key_agreement client operation callback and also
1362 defined the Key Agreement library API for the application.
1364 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1367 is used by clients to request key negotiation between another
1368 client in the SILC network. If the negotiation is started it
1369 is performed using the SKE protocol. The result of the
1370 negotiation, the secret key material, can be used for example
1371 as private message key.
1373 Implemented the Key Agreement payload into the files
1374 lib/silccore/silauth.[ch].
1376 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Redefined ciphers for the SILC protocol. Added some new ciphers
1379 and defined the key lengths for the algorithms. Changed the
1380 code accordingly. The default key length is now 256 bits.
1382 * Fixed SKE key distribution function silc_ske_process_key_material
1383 when the key length is more than 128 bits. The default key
1384 length in SILC is now 256 bits.
1386 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1387 to indicate unsupported algorithm.
1389 * Renamed rijndael.c to aes.c and all functions as well.
1391 * Fixed a long standing channel key setting bug in client library.
1392 Weird that it has never surfaced before.
1394 * Fixed bug in channel deletion. If the entire channel is removed
1395 then it must also delete the references of the channel entry
1396 from the client's channel list as the client's channel entry and
1397 the channel's client entry share same memory.
1399 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1401 * Implemented CONNECT and SHUTDOWN commands in the client.
1403 * Implemented CLOSE command to the client.
1405 * Added the function silc_idlist_find_server_by_name into the
1406 files silcd/idlist.[ch].
1408 Added the function silc_idlist_find_server_by_conn into the
1409 files silcd/idlist.[ch].
1411 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * DIE command was renamed to SHUTDOWN. Updated the both code
1416 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1417 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1419 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1422 * Added function silc_server_create_connection function to create
1423 connection to remote router. My server implementation actually
1424 does not allow router to connect to normal server (it expects
1425 that normal server always initiates the connection to the router)
1426 so the CONNECT command is only good for connecting to another
1429 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1432 or some other client was kicked from the channel.
1434 Implemented the handling of the notify type to both client
1437 Implemented silc_server_send_notify_kicked to send the KICKED
1438 notify. It is used to send it to the server's primary router.
1440 * Implemented the KICK command into server and client.
1442 * Added `query' argument to the silc_idlist_get_client function
1443 to indicate whether to query the client from server or not if
1446 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1447 to indicate that the client is not channel founder.
1451 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1453 * Removed the rng context from SilcPacketContext structure and
1454 changed that the packet routine uses the Global RNG API.
1456 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Added support for quit message that client can "leave" on the
1459 channel when it quits the SILC. It is ditributed inside the
1460 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1462 Added silc_server_free_client_data that will take the
1463 signoff message as argument.
1465 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1467 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Updated parts of the protocol specification to keep it up
1472 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1475 payloads in one packet.
1477 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1478 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1479 use now the new List flag.
1481 * Also deprecated the following packet types: REPLACE_ID,
1482 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1484 * Added list support for Notify packet in server.
1486 * Added silc_server_send_notify_channel_change to send the
1487 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1488 the silc_server_send_replace_id.
1490 * Added silc_server_send_notify_nick_change to send the
1491 NICK_CHANGE notify type. Deprecates the function
1492 silc_server_send_replace_id.
1494 * Added silc_server_send_notify_join to send the JOIN notify type.
1495 Deprecates the function silc_server_send_new_channel_user.
1497 * Added silc_server_send_notify_leave to send LEAVE notify type.
1498 Deprecates the function silc_server_send_remove_channel_user.
1500 * Added silc_server_send_notify_cmode and
1501 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1502 types. Deprecates the silc_server_send_set_mode function.
1504 * Added SERVER_SIGNOFF notify type to indicate that server has
1505 quit. This means that all clients on the channel from that
1506 server will drop. This can be also used when netsplit happens.
1508 Deprecated REMOVE_ID packet type since it is not needed anymore
1511 Added silc_server_send_notify_server_signoff to send the
1512 SERVER_SIGNOFF notify type. Deprecates the function
1513 silc_server_send_remove_id.
1515 Added also silc_server_send_notify_signoff to send the
1516 SIGNOFF notify type.
1518 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1519 SILC protocol from this day on. Changed the protocol
1520 specification as well.
1522 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1523 notify type. It is used between routers to notify about
1524 topic changes on a channel.
1526 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1529 * Partly updated the protocol specification to comply with the
1530 changes now made. It is still though a bit outdated.
1532 * The JOIN notify type now takes one extra argument <Channel ID>.
1533 The packet used to be destined to the channel but now the
1534 JOIN type may be sent as list thus it is impossible to
1535 destine it to any specific channel. By adding this argument
1536 it is again possible.
1538 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Added CREDITS file. The CHANGES and CREDITS file will appear
1541 in the distribution as well.
1543 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1546 types in the server's silcd/packet_receive.c.
1548 * Implemented CMODE and CUMODE to work in router environment.
1550 * Fixed minor encoding and decoding buglet from the
1551 lib/silccore/silcmode.c.
1553 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1556 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1558 * Changed all SilcConfigServer* and silc_config_server* to
1559 SilcServerConfig* and silc_server_config*, respectively.
1562 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Associated the ID (client or server ID) to the Authentication
1565 Payload to avoid any possibility of forging. Updated the
1566 protocol specification and the code accordingly.
1568 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * The RSA key length is now save to the RsaKey context in the
1571 key generation process in lib/silccrypt/rsa.c. The key length
1572 is now used to figure out the maximum size of the block allowed
1573 to be encrypted/signed.
1575 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1576 is equivalent to the silc_mp_mp2bin but does not allocate any
1579 * Changed silc_mp_mp2bin API to take length argument. If it is
1580 non-zero then the buffer is allocated that large. If zero, then
1581 the size is approximated using silc_mp_sizeinbase, which however
1584 * Created Global RNG API which is global RNG that application can
1585 initialize. After initializing, any routine anywhere in the
1586 code (including library) can use RNG without allocating a new
1587 RNG object. This was done to allow this sort of use of the
1588 RNG in code that has no chance to allocate RNG object. All
1589 applications currently allocate this and many routines in the
1590 library use this. Affected file lib/silccrypt/silcrng.[ch].
1592 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1593 it to use the Global RNG API.
1595 * Defined Authentication Payload into protocol specification that
1596 is used during SILC session to authenticate entities. It is
1597 used for example by client to authenticate itself to the server
1598 to obtain server operator privileges.
1600 Implemented this payload into the lib/silccore/silcauth.[ch].
1601 Implemented also routines for public key based authentication
1602 as the new protocol specification dictates.
1604 Moved definitions of different authentication methods from
1605 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1607 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1608 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1609 silc_pkcs_verify_with_hash functions into the file
1610 lib/silccrypt/silcpkcs.[ch].
1612 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * The client entry's userinfo pointer must be always valid.
1615 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1616 will fail since it requires the userinfo. Now, the userinfo
1617 is allocated as "" if actual userinfo does not exist. Actually,
1618 it must exist and it is totally Ok to drop client connections
1619 that does not announce the userinfo. However, we will make
1620 this workaround for now.
1622 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1623 to return the remote port by socket.
1625 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1628 SILC_SERVER_PENDING_EXEC and added an new macro
1629 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1630 data or when error occurs while processing the pending command.
1632 Added new argument `destructor' into silc_server_command_pending
1633 and to the SilcServerCommandPending object. This destructor is
1634 now called after calling the pending callback or if error occurs
1635 immediately. If error occurs the actual pending callback won't
1636 be called at all - only the destructor. The destructor may be
1637 NULL if destructor is not needed.
1639 All this applies for client library code as well. Similar
1640 changes were made there as well for the pending commands.
1642 In the client, the application must now allocate the
1643 SilcClientCommandContext with the silc_client_command_alloc
1646 * Added reference counter to the SilcServerCommandContext. Added
1647 function silc_server_command_alloc and silc_server_command_dup
1650 Same type of functions added to the client library for the same
1653 * Removed the cmd_ident from IDListData away since it is now
1654 global for all connections. It is the command identifier used
1655 in command sending and with pending commands. The affected file
1658 * Added reference counter to the SilcSocketConnection objecet to
1659 indicate the usage count of the object. The object won't be
1660 freed untill the reference counter hits zero. Currently only
1661 server uses this, and client ignores it. The client must be
1662 set to use this too later. The affected files are
1663 lib/silccore/silcsockconn.[ch]. Added also the function
1664 silc_socket_dup to increase the reference counter.
1666 This was mainly added because it is possible that the socket
1667 is removed underneath of pending command or other async
1668 operation. Now it won't be free'd and proper DISCONNECTING
1669 flags, etc. can be set to avoid sending data to connection that
1670 is not valid anymore.
1672 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1673 the connection. After that it sets SILC_SET_DISCONNECTED.
1674 It is, however, possible that the socket data is not still freed.
1675 The silc_server_packet_process now checks that data is not
1676 read or written to connection that is DISCONNECTED. The socket
1677 get's freed when the reference counter hits zero.
1679 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Changed the client operation API: channel_message operation's
1682 `sender' is now the client entry of the sender, not the nickname
1683 and the `channel' is the channel entry, not the channel name.
1685 In the private_message operation the `sender' is now also the
1686 client entry of the sender not the nickname.
1688 Affected file is lib/silcclient/ops.h and all applications
1689 using the client operations.
1691 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Moved the calling of ops->connect() from connect_to_server_final
1694 into receive_new_id functin since that is the point when the
1695 client is actually allowed to send traffic to network. The
1696 affected file is lib/silcclient/client.c.
1698 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1701 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1702 (if needs broadcasting) instead of broadcasting the packets one
1703 by one which would make a burst in the network traffic.
1705 * Added `broadcast' argument to the functions in silcd/server.[ch]
1706 silc_server_create_new_channel[_with_id] to indicate whether
1707 to send New Channel packet to primary router.
1709 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Added new function into the silcd/server.[ch] files:
1712 silc_server_create_new_channel_with_id to create new channel with
1713 already existing Channel ID.
1715 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1716 lib/silccore/silcpacket.h. This packet is used t send list of
1717 Set Mode payloads inside one packet. Server uses this to set
1718 the modes for the channels and clients on those channels, that it
1719 announced to the router when it connected to it. The protocol
1720 specification has been updated accordingly.
1722 * The silc_server_new_channel did not handle the packet coming
1723 from normal server as it normally does not send that. However,
1724 when it announces its channels it does send it. Implemented
1725 the support for that.
1727 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1728 into the file lib/silccore/id.h.
1730 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Fixed memory leaks in the functions silc_idlist_del_client,
1733 silc_idlist_del_channel and silc_idlist_del_server in the file
1734 silcd/idlist.c. All of those leaked like a sieve.
1736 * Fixed some small memory leaks in the client's function
1737 silc_client_notify_by_server.
1739 * Added functions into silcd/server.c: silc_server_announce_clients,
1740 silc_server_announce_channels and silc_server_announce_server.
1741 These functions are used by normal and router server to announce
1742 to its primary router about clients, channels and servers (when
1743 router) that we own. This is done after we've connected to the
1746 These functions effectively implements the following packet types:
1747 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1748 and SILC_PACKET_NEW_ID_LIST.
1750 * Added new functions into the silcd/packet_receive.[ch]:
1751 silc_server_new_id_list, silc_server_new_channel_list and
1752 silc_server_new_channel_user_list to handle the incoming
1753 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1755 * Added support of changing Channel ID in the function
1756 silc_server_replace_id. If the server that announces a channel
1757 to the router already exists in the router (with same name but
1758 with different Channel ID), router is responsible to send
1759 Replace ID packet to the server and force the server to change
1760 the Channel ID to the one router has.
1762 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1763 client that the Channel ID has been changed by the router. The
1764 normal server sends this to the client. Client must start using
1765 the new Channel ID as the channel's ID.
1767 Implemented handling of this new type into lib/silcclient/client.c
1768 into the function silc_client_notify_by_server.
1770 * Added new function silc_idlist_replace_channel_id into the files
1771 silcd/idlist.[ch] to replace the Channel ID.
1773 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Call silc_server_command_identify_check always when processing
1776 the IDENTIFY command in silcd/command.c
1778 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1781 send keepalive packets. The packet can be sent by clients,
1782 servers and routers.
1784 Added function silc_socket_set_heartbeat into the file
1785 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1786 If not set, the heartbeat is not performed. The actual
1787 heartbeat is implemented in the low level socket connection
1788 library. However, application is responsible of actually
1791 Added silc_server_send_heartbeat to send the actual heartbeat
1792 packet into silcd/packet_send.[ch]. Server now performs
1793 keepalive with all connections.
1795 * Added silc_task_get_first function into lib/silcutil/silctask.c
1796 to return the timeout task with shortest timeout. There was a bug
1797 in task unregistration that caused problems. TODO has been
1798 updated to include that task system must be rewritten.
1800 * The client library will now resolve the client information when
1801 receiving JOIN notify from server for client that we know but
1802 have incomplete information.
1804 * Rewrote parts of silc_server_remove_from_channels and
1805 silc_server_remove_from_one_channel as they did not remove the
1806 channel in some circumstances even though they should've.
1808 * Encryption problem encountered in server:
1810 The LEAVE command used to send the Channel Key packet to the
1811 router immediately after generating it. However, the code
1812 had earlier sent Remove Channel user packet but not immediately,
1813 ie. it was put to queue. The order of packets in the router
1814 was that Channel Key packet was first and Remove Channel User
1815 packet was second, even though they were encrypted in the
1816 reverse order. For this reason, MAC check failed. Now, this
1817 is fixed by not sending the Channel Key packet immediately but
1818 putting it to queue. However, this is more fundamental problem:
1819 packets that are in queue should actually not be encrypted
1820 because packets that are sent immediately gets encrypted
1821 actually with wrong IV (and thus MAC check fails). So, packets
1822 that are in queue should be encrypted when they are sent to
1823 the wire and not when they put to the queue.
1825 However, the problem is that the current system has not been
1826 designed to work that way. Instead, the packet is encrypted
1827 as soon as possible and left to the queue. The queue is then
1828 just purged into wire. There won't be any fixes for this
1829 any time soon. So, the current semantic for packet sending
1832 o If you send packet to remote host and do not force the send
1833 (the packet will be in queue) then all subsequent packets to the
1834 same remote host must also be put to the queue. Only after the
1835 queue has been purged is it safe again to force the packet
1838 o If you send all packets immediately then it safe to send
1839 any of subsequent packets through the queue, however, after
1840 the first packet is put to queue then any subsequent packets
1841 must also be put to the queue.
1843 Follow these rules and everything works fine.
1845 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * Added new function silc_server_remove_clients_by_server to
1848 remove all client entries from ID list when the server connection
1849 is lost. In this case it is also important to invalidate all
1850 client entires as they hold the invalid server entry. This
1851 fixes fatal bug when server has lost connection and will reconnect
1854 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Made some sanity checks to silc_server_daemonise like to check
1857 whether the requested user and group actually exists.
1859 * Added sanity check to SKE's silc_ske_responder_finish to check
1860 that the public and private key actually is valid.
1862 * Invalidate the client's nickname when receiving Replace ID
1863 packet and the Client ID is being replaced. This means that the
1864 server will query the nickname if someone needs it (client)
1867 * Sort the ID Cache in client library when the ID Cache data
1868 has changed (needs sorting).
1870 * Do not allow for SILC client to create several connections to
1871 several servers. The client does not support windows right now
1872 and generating multiple connections causes weird behaviour.
1874 Irssi-silc client does support windows and can handle several
1875 connections without problems, see: www.irssi.org and SILC plugin.
1877 * Fixed some places where client was added to the IDList. The
1878 rule of thumb is following (in order to get everything right):
1879 If the client is directly connected local client then the
1880 `connection' argument must be set and `router' argument must be
1881 NULL to silc_idlist_add_client function. If the client is not
1882 directly connected client then the `router' argument must
1883 bet set and the `connection' argument must be NULL to the
1884 silc_idlist_add_client function.
1886 * The funtion silc_server_packet_send_local_channel actually did
1887 not check whether the client was locally connected or not. It
1888 does that now. Fixed a bug related to LEAVE command.
1890 * Fixed Remove Channel User payload parsing bug in server's
1891 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1893 * The server's silc_server_save_channel_key now checks also the
1894 global ID list for the channel as it might not be in the local
1895 list. Fixed a bug related to LEAVE command.
1897 * Is this the end of the [<unknown>] buglet that has been lurking
1898 around for a long time? A little for loop fix in server's
1899 silc_server_command_whois_parse that is used by both IDENTIFY
1900 and WHOIS command. At least, this was a clear bug and a cause
1901 of one type of [<unknown>] buglet.
1903 * WHOIS and IDENTIFY commands call the function
1904 silc_server_command_[whois/identify]_check function even if
1905 we are not router server.
1907 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Added --with-gmp configuration option. If set the GMP
1910 is always compiled in the SILC source tree. If not set then
1911 it is checked whether the system has the GMP3 installed. If
1912 it has then the GMP won't be compiled (the system's headers
1913 and library is used), if it doesn't have it then the GMP is
1914 compiled in the SILC source tree.
1916 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Changed RSA private exponent generation to what PKCS #1
1919 suggests. We try to find the smallest possible d by doing
1920 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1921 not security fix but optimization.
1923 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Added new config entry [Identity] to fork the server and run
1926 it as specific user and group. A patch from Bostik.
1928 * Imported Dotconf configuration library into lib/dotconf.
1929 This will be used to create the SILC configuration files later.
1930 It will appear in the distsribution after this commit.
1932 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * A big code auditing weekend happening. Auditing code for
1935 obvious mistakes, bugs and errors. Also, removing any code
1938 Removed files for being obsolete:
1940 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1941 inline in the file lib/silcutil/silcbuffer.h)
1943 o lib/silcutil/silcbufutil.c (the header has inline versions)
1945 Changed code to fix possible error conditions:
1947 o The buffer formatting routines now check that the destination
1948 buffer really has enough space to add the data. This applies for
1949 both buffer formatting and unformatting
1950 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1951 unformatting was changed to accomodate following rules:
1952 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1953 sent to the function while XXX_*STRING will not allocate or copy
1954 the data into the buffer. Instead it sets the pointer from the
1955 buffer into the pointer sent as argument (XXX_*STRING used to
1956 require that the pointer must be allocated already). This change
1957 makes this whole thing a bit more consistent and more optimized
1958 (note that the data returned in the unformatting with XXX_*STRING
1959 must not be freed now). The routines return now -1 on error.
1961 o Tried to find all code that use buffer_format and buffer_unformat
1962 and added return value checking to prevent formatting and
1963 especially unformatting errors and possible subsequent fatal
1966 o Changed ske->x and ske->KEY to mallocated pointers in
1967 lib/silcske/silcske.h. Fixed possible data and memory leak.
1969 o Added return value checking to all *_parse* functions. Fixed
1970 many memory leaks as well.
1972 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1973 so that buffer overflows would not happen. All code now also
1974 checks the return value as it can fail.
1976 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added reconnection support to server if the normal server looses
1979 its connection to the router (for example if router is rebooted).
1980 The server performs normal reconnection strategy implemented
1981 to the server. Affected file silcd/server.c.
1983 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added new packet type SILC_PACKET_SET_MODE that is used to
1986 distribute the information about changed modes (for clients,
1987 channels and clients channel modes) to all routers in the
1988 network. Updated the protocol specification accordingly.
1990 Added functions into silcd/packet_send.c and
1991 silcd/packet_receive.c: silc_server_send_set_mode,
1992 silc_server_set_mode.
1994 Added new files silcmode.[ch] into lib/silccore that implements
1995 the encoding and decoding of Set Mode Payload. Added new type
1996 SilcSetModePayload. Moved the definitions of different modes
1997 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1999 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Oops, a little mistake in server's connection authentication
2002 protocol. The protocol is not ended with FAILURE but with
2003 SUCCESS if the authentication is Ok. :) Affected file is
2006 * Implemented NICK_CHANGE notify handling in server in the file
2007 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2008 the local clients on the channel. After the changing nickname
2009 in router environment snhould work and the [<unknown>] nickname
2010 should appear no more.
2012 The silc_server_replace_id function that receives the Replace ID
2013 payload now sends the NICK_CHANGE notify type also in the file
2014 silcd/packet_receive.c
2016 * Changed WHOIS and IDENTIFY command to support the maximum amount
2017 of arguments defined in protocol specs (3328 arguments). This
2018 fixed a bug that caused problems when there were more than three
2021 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Added extra parameter, command identifier, to the
2024 silc_client_send_command so that explicit command identifier
2027 Changed that ID list routines uses specific command identifier
2028 when sending WHOIS/IDENTIFY requests to the server so that they
2029 can be identified when the reply comes back.
2031 Affected files lib/silcclient/command.[ch],
2032 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2034 * Added `sender' argument to silc_server_packet_send_to_channel
2035 to indicaet the sender who originally sent the packet to us
2036 that we are now re-sending. Ignored if NULL. Affected file
2037 silcd/packet_send.[ch].
2039 * Added some server statistics support in silcd/server_internal.h
2040 SilcServerStatistics structure and around the server code. Also
2041 send some nice statistics information when client is connecting
2044 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Fixed channel ID decoding in server's JOIN command reply in
2047 silcd/command_reply.c
2049 * Fixed braodcasting of replace ID payload to not to send it if
2050 we are standalone server in silcd/packet_receive.c.
2052 * Fixed all channel message sending routines to not to send
2053 packets to clients that has router set, since they are routed
2054 separately in the same function earlier. Affects file
2055 silcd/packet_send.c and all channel packet sending functions.
2057 * In USERS reply, res_argv[i] are not allocated, the table
2058 is allocated. Thus changed that free the table, not its
2061 * In server's whois_check and identify_check if the client is
2062 locally connected do not send any WHOIS commands - they are not
2065 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Fixed some minor bugs in client when sending WHOIS command. The
2068 arguments was in wrong order.
2070 * Removed statis function add_to_channel from server in
2071 silcd/command.c that was previously used with the joining but
2074 * Tested USERS command in router environment successfully with two
2075 routers, two servers and two clients.
2077 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Reorganized the USERS command and command reply in client library
2080 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2081 When the command is given by user we register a pending command
2082 callback that will reprocess the command after the reply has been
2083 received from the server. When reprocessing the packet we then
2084 display the information. Thus, the USERS information is displayed
2085 now in the command callback instead of in the command reply
2086 callback. The processing of the command is same as previously
2087 when server has sent the command reply in the JOINing process.
2089 * Added to USERS command in silcd/command_reply.c to join the client,
2090 we didn't use to know about, to the channel after we've created
2091 a client entry for it. Also, for clienet we did know already still
2092 check whether it is on the channel or not and add it if not.
2094 * Removed silc_server_command_join_notify as the function and its
2097 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Changed the client's pending command handling to the same as the
2100 server's pending command handling. It is also now possible to
2101 execute command reply functions from other command reply
2102 function as the function callbacks for commands and command
2103 replies are one and same. The pending commands are not static
2104 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2105 in client connection context. Thus, pending commands are server
2106 connection specific as it is convenient.
2108 Changed the function silc_client_command_pending and
2109 silc_client_command_pending_del and added new function
2110 silc_client_command_pending_check. Removed the
2111 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2114 * Added cmd_ident, current command identifier, to the client
2115 connection context in lib/silcclient/client.h to keep track on
2116 command identifiers used in command sending. Client's command reply
2117 function handling now supports the mandatory command identifiers.
2119 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2120 funtions in client to fully support pending command callbacks.
2122 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2123 as one of the arguments to the application in the command reply
2126 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2127 before first releasing SILC but came back. Now it is removed again
2128 and should come back nomore. The FORWARDED flag was used only
2129 by the JOINing procedure by forwarding the command packet to router.
2130 Now, the JOINing procedure has been changed to more generic (due
2131 to various router environment issues) and FORWARDED is not needed
2132 anymore for anything. The protocol specification is yet to be
2135 Now, removed silc_server_packet_forward from server and the flag
2136 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2138 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Renamed NAMES command to USERS command. The NAMES was named that
2141 due to historical reasons. Now it is renamed. Also, rewrote
2142 parts of the USERS command. The nickname list is not sent anymore
2143 by the server. Only Client ID and mode lists are sent in the USERS
2144 command. Changed this also to the protocol specification.
2146 The client now resolves the names and stuff after it receives
2147 the USERS list from the server when joining to the channel.
2149 * WHOIS and IDENTIFY commands has been changed to support multiple
2150 Client ID's per command. One can now search for multiple users
2151 in the network by sending only one WHOIS or IDENTIFY command.
2152 Changed the code and the protocol specifications.
2154 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2155 uses silc_server_command_whois_parse to parse the request. */
2157 * If normal server, do not parse the WHOIS and IDENTIFY requests
2158 before sending it to the router. Saves some time.
2160 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Fixed JOIN command on client library. Wrong number of arguments
2163 used to crash the client.
2165 * Added silc_server_channel_has_global function to check whether
2166 channel has global users or not.
2168 * Added silc_server_channel_has_local function to check whether channel
2169 has locally connected clients on the channel.
2171 * The silc_server_remove_from_one_channel now checks whether the
2172 channel has global users or not after given client was removed from
2173 the channel. It also checks whether the channel has local clients
2174 on the channel anymore. If it does not have then the channel entry
2175 is removed as it is not needed anymore.
2177 * The silc_server_notify now checks on JOIN notify whether the joining
2178 client is one of locally connected or global. If it is global then
2179 the channel has now global users on the channel and that is marked
2180 to the channel entry. Also, it now saves the global client to
2181 global list who is joining and JOINs it to the channel. This is
2182 for normal server, that is.
2184 Changed silc_server_send_notify_on_channel,
2185 silc_server_packet_relay_to_channel and
2186 silc_server_packet_send_to_channel check if we are normal server
2187 and client has router set (ie. global client) do not send the
2188 message to that client, as it is already routed to our router.
2190 * Implemented LEAVE notify type handling in silc_server_notify
2193 * Tested LEAVE command in router environment successfully. Tested
2194 with two routers, two servers and two clients.
2198 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2200 * Implemented SIGNOFF notify type handling in silc_server_notify
2203 * silc_server_remove_id now removes the client entry from all channels
2204 it has joined and thusly sends SIGNOFF notify type.
2206 * Rewrote the NAMES list generation in server by removing two excess
2207 loops. The lists are created now inside one loop.
2209 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * silc_server_remove_channel_user checks now also global list
2212 for channel and client.
2214 * silc_server_new_channel_user checks now both local and global
2215 list for channel and client. Fixed a bug in client id decoding.
2216 Used to decode wrong buffer.
2218 * silc_server_channel_message checks now both local and global
2219 list for channel entry.
2221 * Tested channel joining (hence JOIN) in router environment
2222 successfully. Tested with two routers, two servers and two
2225 * Tested channel message sending in router environment successfully.
2227 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Added silc_server_save_channel_key into server.[ch] to save the
2230 received channel key in Channel Key payload processing. It is
2231 also used in JOIN command reply handling.
2233 Equivalent function silc_client_save_channel_key added into
2234 client.[ch] into client library.
2236 * Changed JOIN command reply to send information whether the channel
2237 was created or not (is existing already) and the channel key
2238 payload. Changed protocol specs accordingly.
2240 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2241 the request was sent by ID and not by nickname. Crashed on
2244 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2247 now correctly save the received data.
2249 * silc_server_free_sock_user_data now notifies routers in the
2250 network about entities leaving the network.
2252 At the same time implemented functions silc_server_remove_id
2253 and silc_server_send_remove_id to receive and send REMOVE_ID
2254 packets. The packet is used to notify routers in the network
2255 about leaving entities. The ID removed will become invalid in
2258 * Added function silc_idlist_del_server into server. Removes and
2259 free's server entry from ID list.
2261 * silc_server_private_message function now checks, if we are router,
2262 that the destination ID really is valid ID, naturally.
2264 * In router when NEW_ID packet is received (for new client) the
2265 hash of the Client ID is saved in the ID Cache but the
2266 client->nickname is set to NULL, instead of putting the hash
2269 IDENTIFY command now also checks that client->nickname must be
2270 valid. If it is not if will request the data from the server who
2271 owns the client. Added new function
2272 silc_server_command_identify_check.
2274 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2275 to set the command to already allocated Command Payload.
2277 * Tested private message sending in router environment with two
2278 routers, two servers and two clients. Fixed minor bugs and now
2281 * Fixed segfault from client's NAMES command. Used to crash if
2284 * Forwarded packets must not be routed even if it is not destined
2285 to the receiver. Changed server code comply with this.
2287 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Added `require_reverse_mapping' boolean value to ServerParams
2290 structure. If TRUE (not default) the server will require that
2291 the connecting host has fully qualified domain name.
2293 If the reverse mapping is not required and hostname could not be
2294 found the IP address is used as hostname.
2296 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Implemented version string checking to both client and server.
2299 The check is incomplete currently due to the abnormal version
2300 strings used in development version of SILC.
2302 * Changed all command functions in server to use the new
2305 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Changed char *data to unsigned char *data in ID Cache system to
2308 support binary data as ID Cache data. Changed code to support
2309 binary data in lib/silccore/idcache.c.
2311 * Renamed silc_server_packet_relay_command_reply to
2312 silc_server_command_reply as it is normal packet receiving
2313 function. Rewrote the function to accept command replys for
2314 servers and not only for clients.
2316 * Mark remote router always as registered server if we are connecting
2317 to it. Otherwise, commands sent by the router to us are ignored.
2319 * All ID List find routines now returns the ID Cache Entry pointer
2320 as well if requested.
2322 * WHOIS command works now in router environment, tested with two
2323 routers, two servers and two clients.
2325 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2326 in router environment (as it is almost equivalent to WHOIS) but
2327 hasn't been tested thoroughly. Added new functions:
2329 silc_server_command_identify_parse
2330 silc_server_command_identify_send_reply
2331 silc_server_command_identify_from_client
2332 silc_server_command_identify_from_server
2334 * Disabled route cache adding because adding two different ID's with
2335 same IP replaces the old cache entry thus giving wrong route.
2336 The entry->router->connection is always the fastest route anyway
2337 so route cache may not be needed. Of course, new routes maybe
2338 established after receiving the ID when the entry->router->connection
2339 might not be anymore the most optimal.
2341 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Add route cache for received ID for fast routing.
2345 * Added silc_server_packet_route to route received packet on router
2346 that is not destined to us.
2348 * Renamed silc_server_get_route to silc_server_route_get.
2350 * Added id_string and id_string_len fields into SilcServer to
2351 include encoded ServerID for fast comparing without excess
2352 encoding of the ID's.
2354 * Cleaned up WHOIS command on server side. Added following static
2357 silc_server_command_whois_parse
2358 silc_server_command_whois_check
2359 silc_server_command_whois_send_reply
2360 silc_server_command_whois_from_client
2361 silc_server_command_whois_from_server
2363 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2364 arguments in command replies. All command functions should be
2365 updated to use this macro.
2367 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Minor typo fixes on command reply handling on server.
2371 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added silc_server_command_add_to_channel internal routine to add
2374 the client to the channel after router has created the channel and
2375 sent command reply to the server.
2377 * Added generic silc_server_send_command to send any command from
2380 * Use static buffer with ID rendering instead of duplicating data.
2382 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Fixed a channel user mode bug when joining to a channel server gave
2385 everybody channel founder rights, oops.
2387 * We mark ourselves as the router of the incoming server connection
2388 if we are router ourselves. This way we can check in some packet
2389 sending functions whether it is locally connected server. For
2390 incoming router connections we put NULL.
2392 * For router sending packets locally means now always sending the
2393 packet cell wide; to local clients and local servers. For normal
2394 server sending packet locally means sending it to only local
2397 * Fixed the JOIN command to really work in router environment. If the
2398 channel is created it is always created by the router. Router is
2399 also responsible of making the initial joining to the channel,
2400 sending JOIN notify to the sending server and distributing
2401 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2402 does not exist server doesn't do anything else but forward the
2403 command to the router which performs everything.
2405 * Added silc_server_send_channel_key function to send the Channel Key
2408 * Added silc_server_create_channel_key to create new channel key. The
2409 channel key is now re-generated everytime someone joins or leaves
2410 a channel, as protocol dictates. Note: channel->key_len is the
2413 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2416 packet_receive.[ch] to separate packet sending and receiving
2417 routines. The server.[ch] now includes everything else including
2418 actual packet processing (writing and reading data) and other
2421 Renamed silc_server_private_message_send_internal to
2422 silc_server_send_private_message. The routine is still though
2423 used only to relay private messages as server does not send
2424 private messages itself.
2426 Renamed silc_server_new_channel to silc_server_create_new_channel
2427 and added new function sicl_server_new_channel that handles the
2428 incoming New Channel packet. Added also new sending function
2429 silc_server_send_new_channel to send New Channel Payload.
2431 * Added new function silc_server_notify to process incoming notify
2432 packet to the server/router. Server may then relay the notify
2433 to clients if needed.
2435 * Added new function silc_server_new_channel_user to process incoming
2436 New Channel User packet. Router will redistribute the packet and
2437 send JOIN notify to its local clients and locally connected servers
2438 if needed. Normal server will send JOIN notify to its local client
2439 on same channel when received this packet. Added also corresponding
2440 sending function silc_server_send_new_channel_user to sent the
2443 * Added boolean route argument to send_notif_to_channel and
2444 packet_send_to_channel functions to attempt to route the packet
2445 if it is TRUE and send only locally if it is FALSE.
2447 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * silc_server_replace_id now broadcasts the received replace ID
2450 packet if it is not broadcast packet already. The router must
2451 broadcast to inform other routers about changed ID.
2453 * Added backpointer to server's router into SilcServer context in
2454 silcd/server_internal.h.
2456 * Fixed silc_server_packet_broadcast to send correct broadcast
2459 * The channel key is now distributed to the local client as soon
2460 as it is received from the router (in router environment) so that
2461 no other packet may be sent for the channel until client has
2464 * silc_server_remove_channel_user now broadcasts the received
2465 Remove Channel User packet if it is not broadcast packet already.
2466 The router must broadcast to inform other routers about removed
2469 * Added users field into SilcPacketContext that is a reference count
2470 of the context. One can increase the reference count by calling
2471 silc_packet_context_dup which is now changed to just increase the
2472 reference count instead of duplicating the data. The reference
2473 count is decresed by calling silc_packet_context_free that will
2474 free the data after the reference count hits zero.
2476 For now on the packet context and everything allocated into it
2477 (including the raw packet from network) must be freed by calling
2478 the new silc_packet_context_free function. Added also new function
2479 silc_packet_context_alloc that must be used now to allocate the
2480 context. This also means that if a routine is asynchronous from
2481 silc_[client/server]_packet_parse_type the packet context must
2482 be duplicated by calling silc_packet_context_dup. Otherwise it
2483 gets free'd after silc_[client/server]_packet_parse_type returns.
2484 Also, one must remember that if packet is duplicated then its
2485 reference count must be decresed by calling the free function as
2486 many times as it was duplicated.
2488 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2489 from both client and server.
2491 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Made joining to a channel working in router environment.
2495 * Cleaned up JOIN command on server side and create function
2496 silc_server_command_join_channel internal routine to make the
2499 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Changed silc_command_pending list to SilcDList. Also, added
2502 `ident' field to SilcServerCommandPending structure to identify
2503 the reply and to call correct callback.
2505 Added silc_server_command_pending_check function to replace the
2506 corresnponding macro. The silc_command_pending list is not
2509 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2510 to set identifier to previously allocated Command Payload. It
2511 is used to set identifier for command when resending Command
2514 * Added silc_command_payload_encode_payload to encode Command
2515 Payload buffer from SilcCommandPayload structure.
2517 * Added silc_argument_payload_encode_payload to encode Argument
2518 payload buffer from SilcArgumentPayload structure.
2520 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Changed WHOIS command to support router connection on server side.
2523 The whois request is always sent to router unless the server is
2524 standalone server. After server has received the reply from the
2525 router will it send the reply to the client.
2527 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2528 broadcast received broadcast packet. The function is used only
2529 by router. The broadcast packet is always sent to the router's
2532 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2533 render given ID to printable string, for log files for example.
2535 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Made basic router to router connections working. At least they
2538 can now connect to each other but nothing really works the way
2539 they are supposed - yet.
2541 * Added new initiator token to RouterConnection configuration
2542 file in silcd/serverconfig.[ch]. It is used to tell whether we
2543 are the initiator to the remote router or whether we'll expect
2544 the other end to connect.
2546 * Moved registering of listener task to silc_server_init, hence
2547 the server starts listenning as soon as it is run, even if it
2548 does not have connections to other routers. Let's see how well
2551 * Changed default connection retry timeouts for more suitable in
2554 * Removed cipher and such arguments from silc_idlist_add_client
2555 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2556 Added new function silc_idlist_add_data to add the keys and stuff
2559 * Added SilcIDListData structure and added it to SilcClientEntry
2560 and SilcServerEntry as their first field in the structure. This
2561 way we can explicitly cast the ID entries to the SilcIDListData
2562 structure and get common data for the entries. In past, we had
2563 to first check what type of connection it is and then cast it to
2564 correct ID entry type. Now, we can directly cast the opaque
2565 pointer to the SilcIDListData (no matter what ID entry it actually
2566 is) and get the data needed.
2568 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2571 in some circumstances even if threre were timeout tasks, though not
2572 IO tasks, but tasks anyway. Now fixed.
2574 * Defined SilcServerConnection structure to hold connection specific
2575 stuff about directly connected servers and routers. The definition
2576 is currently in silcd/server_internal.h. I thought about having
2577 a bit more important role fro this struct but for now it is used
2578 only when connecting to other server (or router actually).
2580 * Added connecting retry support in server when connecting to
2581 router(s). The retry feature implement exponential backoff
2582 algorithm. Also, added SilcServerParams structure to hold default
2583 parameters for server. For now, it include these retry settings
2584 and are hard coded. After server is moded to be as Silc Server
2585 Library this structure will be more important.
2587 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Changed client librarys channel->clients table to SilcList and
2590 changed code accordingly.
2592 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Changed client's channel table to SilcList and changed code
2595 accordingly. Also changed SilcChannelClientEntry to include back-
2596 pointer to the channel so that client entry can use that structure
2597 as list as well and we have fast cross-reference to the channel.
2598 This change dramatically decreased the complexity of channel
2599 handling with client entry and vice versa (removed one extra
2600 loop when searching for channel entry from many functions).
2602 * Changed server->sim from table to SilcDList and changed code
2605 * NAMES command can now be used from user interface. It will show
2606 the user list on the channel, neatly.
2608 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2609 Code now saves realname of the user if it becomes available.
2611 * Renamed configure.in to configure.in.pre and made ./prepare
2612 script to automatically add correct version string to
2613 configure.in which it creates from configure.in.pre.
2615 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * NAMES command reply now shows users mode with the nickname when
2620 * Moved silc_client_ch[u]mode[_char] functions from
2621 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2622 place sucks, they are utility functions and should be in some
2625 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2627 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2630 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Added TRQ (efficient deque and list library) into lib/trq. This is
2635 a very good list library that is currently used in the SILC. Defined
2636 SilcList API over the library because I didn't like the API very
2637 much. See lib/trq/silclist.h for the API and examples of how to
2638 use the API. Fixed various places in the code to use the new
2639 SilcList API. The SilcList is meant for lists that has a structure
2640 already defined as a list. It is not suitable to add just some
2641 context to the list (in TRQ, the context is the list actually).
2643 So, I defined SilcDList that can be used for the purpose where
2644 predefined list structure does not exit. This can be used as
2645 such list. Now some context just can be added to the SilcDList.
2646 Currently this list is not used in the SILC just yet, though there
2647 are a lot places where this can replace dynamically allocated
2648 tables and I will fix these places, later, to use SilcDList.
2649 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2650 and use TRQ internally).
2652 Also fixed some annoying warning messages that the original TRQ
2653 code generated. Also minor changes to TRQ's Makefile.in.
2655 * Added support for querying by Client ID to both WHOIS and
2656 IDENTIFY commands into server, as required by the protocol.
2658 * Removed method function pointers from SilcBuffer structure. They
2659 weren't used to anything and just increased the context size for
2660 no good reason. This change also made silc_buffer_alloc and
2661 silc_buffer_free functions inline functions.
2663 * Disabled command flooding detection support until it's fixed so
2664 that it accepts commands in but does not execute them more than once
2667 * Added silc_net_localhost(), to return local hostname, into
2668 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2669 that must be initialized before calling silc_client_init.
2671 * Added new function: silc_server_send_notify_on_channels to send
2672 notify messages to all channels client has joined. It is assured
2673 that the message is sent only once per client.
2675 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2676 lib/silcutil/silcutil.[ch] as silc_format function. The new
2677 function is generic and is used by server as well, not only by
2678 the logging routines.
2680 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2681 the provided version string was not acceptable. Added new function:
2682 silc_ske_check_version into lib/silcske/silcske.h. The function
2683 must be implemented by the application (client or server) and it
2684 does not reside in the SKE library. The function checks the version
2685 string remote end sent.
2687 * Added back pointers (to opaque context and to SilcSocketConnection)
2688 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2690 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2691 duplicate packet context structure.
2693 * Changed `notify' client operation to send same arguments as client
2694 receives from server except for ID's. ID's are mapped to correct
2695 ID entry and that is returned. Also, if channel entry is not sent
2696 by server but the notify is for channel the channel entry is sent
2697 to application (otherwise application doesn't know that it is for
2698 channel (library gets it from packet's Destination ID)).
2700 * Added silc_client_remove_from_channels into client library to
2701 remove a client from all channels it has joined to. Used when
2702 received SIGNOFF notify from server. Added also new function
2703 silc_client_replace_from_channels to replace old ID entry with
2704 new ID entry on all channels. Used when received NICK_CHANGE
2707 * Fixed ID Cache list handling in silc_idlist_get_client in
2708 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2709 to get (or query) client by ID.
2711 * Updated TODO list.
2713 * Added connection authentication status message defined by the
2714 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2715 support for these into the code in client and server side.
2717 * Added generic function silc_client_send_command to send any command
2718 with variable argument list. Application should use this function
2719 to send commands if the command functions provided by the library
2720 does not suite for the application's user interface needs.
2722 * Added new `failure' client operation. Application is notified about
2723 received failure packet if client is executing a protocol. In this
2724 case the protocol's execution has failed.
2726 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2727 is required by the protocol.
2729 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2730 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2733 * Added status flag to SilcSKE object to indicate realtime status
2734 of the SKE protocol.
2736 * Application receives now exactly same command reply arguments as
2737 the library receives from server. However, if ID is received the
2738 corresponding ID entry is returned to the application (eg. Client
2739 ID is mapped to correct SilcClientEntry entry and that is returned).
2740 Changed command_reply client operation due to this change.
2742 * Changed all ID's in commands and in command replys as ID Payloads.
2743 Change affected both client and server side codes.
2745 All ID's sent in SILC network (with execption of ID's in SILC
2746 Packet header) are sent in ID Payload to support variable length
2749 * Server now notifies nick changes and notifies all clients on
2750 the channels about the new nickname (about the new Client ID,
2753 * Implemented CMODE command to change channel modes. Supports all
2754 channel modes defined by the protocol specs except ban and invite
2755 lists. (Also, private channel key mode is supported but support for
2756 setting private channel key in client is missing, thus, this mode
2757 has no effect on client side (except that server requires that the
2758 client uses private channel key and normal channel traffic does not
2761 Also, invite mode works per se, but INVITE command does not work
2762 yet correctly, so you can set channel as invite only channel but
2763 inviting clients to the channel does not work (it is yet to be
2764 thought what's the best way to do it).
2766 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2767 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2768 Implemented CUMODE command to change user's mode on the channel.
2769 Supports all modes defined by the protocol specs.
2771 * Added NAMES command reply to return users modes on the channel.
2773 * Removed unnecessary and slow ciphers from lib/silccrypt.
2775 * Set SO_KEEPALIVE option to connection sockets by default.
2777 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2779 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2780 redefined the Notify Payload into protocol specs.
2782 * Added silc_id_payload_parse_id to get ID directly from raw
2785 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2788 accept searching by Client ID as well.
2790 * Added support for LEAVE and SIGNOFF notify types in client library.
2792 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2793 to parse ID Payload from raw data.
2795 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Added flags parameter into silc_ske_assemble_security_properties
2798 function in lib/silcske/silcske.[ch].
2800 * Changed notify client operation to fit better for notify messages
2801 sent by server. The notify payload received from server is now
2802 passed to the application (after parsing it to SilcNotifyPayload).
2803 It is application's responsibility to retrieve the arguments
2804 from the payload and show the message the way it wants. The message
2805 sent by server is implementation specific.
2807 * Changed public keys to comply with the protocol specification.
2808 Old public keys are not supported anymore and are not compatible.
2810 * Removed nickname from Channel Payload as the latest draft removed
2811 it. The client must resolve the nickname from the NAMES command
2812 reply received when it joined the channel.
2814 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2816 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Fixed some errors in protocol specification drafts.
2820 * Created lib/silccore/silcnotify.c to implement Notify Payload
2821 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2822 generic payloads described by protocol specifications. The file
2823 includes implementations for ID Payload and Argument Payload.
2825 * Changed Command Payload implementation to use the new Argument
2826 Payload. Changed command_xxxx_payload to command_payload_xxxx
2827 to comply with SILC coding conventions.
2829 * Added suppport for Argument Payload handling in Notify Payload
2830 implementation as protocol requires it. Added the new support
2831 into server and client lib as well.
2833 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Added support for multiple nicknames on same channel. [n] is
2836 added locally to the nickname if there are more than one same
2837 nicknames on the channel.
2839 * Server now sends all nicknames that matched WHOIS request.
2840 Client also shows the list received from server.
2842 * Added TOPIC command to client side. User can now set and show
2843 current topic on channel.
2845 * Added MOTD command to client and server. Also, server sends the
2846 motd when client connects to the server.
2848 * Changed version strings to comply ISO 8601.
2850 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Fixed protocol error handling in client library. It should now
2853 cope even if the SKE fails for some reason.
2855 * Made new protocol specification drafts for submitting to IETF.
2857 * Implemented TOPIC command to server in silcd/command.c.
2859 * Added two new notify types into lib/silccore/silcnotify.h:
2860 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2861 notify nickname change and topic setting/change on a channel.
2863 * API change of command_reply operation in client library. The
2864 application gets now the status type received from server as well.
2866 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2870 * Cras fixed and optimized the packet handling even further and
2871 it should work now. Minor change to the prototype of function
2872 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2874 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Added new function into lib/silcutil/silcschedule.[ch]:
2877 silc_schedule_with_fd to select() a specified fd. The function
2878 returns after timeout expires or data arrives or goes. The
2879 function is used by packet routines to wait that all data is
2880 received from network.
2882 * Fixed data reading from network in lib/silccore/silcpacket.c.
2883 The code now assures that all data is read from the fd and then
2884 continues packet processing. This was a bug fix since the code
2885 used to drop some data in some circumstances.
2887 * Added new function into lib/silcclient/client.[ch]:
2888 silc_client_start_key_exchange to start key exchange after
2889 connection has been established to server. The code internally
2890 now uses this funtion but its main purpose was to provide it
2891 for applications that perform their own connecting. After
2892 application has created a connection it merely calls this
2893 function to start the key exchange between client and server.
2894 The library takes care of everything else after that.
2896 Updated also lib/silcclient/README to explain the usage of
2899 * Do not send to application information that connection has
2900 been established. Application gets notified it by connect
2903 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Applied cras's patch to add silc_schedule_one function. The
2906 function runs scheduler once and returns.
2908 * Fixed the scheduler after cras messed it up. The timeout
2909 handling works now as it's supposed to work.
2911 * Added into lib/silccore/ silcnotify.h to include notify
2912 message types support. Changed silc_server_send_notify*
2913 functions, in server.[ch], to support those new notify types.
2914 Added the support for the notify types into client library,
2915 as well. Added new notify client operation into ops.h in
2918 * Changed silc_server_packet_send_to_channel to send normal
2919 packets instead of just channel message packets. The function
2920 is now used to send the notify packets to channels. It is not
2921 used to send channel message packets anymore, as server never
2924 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2925 va_arg()s as it seems to require it nowadays. I guess, if SILC
2926 is compiled with older va_arg() the new code should work anyway.
2928 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Splitted core library. Core library (lib/silccore) includes
2931 now only SILC protocol specific core (and common) components.
2932 Created new utility library (lib/silcutil) that includes more
2933 generic purpose stuff. The stuff for util library was taken
2934 from the old core library. This was minor and easy split.
2936 * Created SILC Client Library (lib/silcclient) that includes
2937 implementation of the SILC client without user interface. This
2938 was major move from silc/ directory. The code has been changed
2939 so that it is transparent towards the user interface. The
2940 silc/ directory includes now the same user interface as before
2941 and it uses the new client library. Read lib/silcclient/README.
2942 Basicly, the client library performs everything else related
2943 to SILC except user interface handling. Also, configuration
2944 files are considered to be part of user interface and library
2945 does not handle them.
2947 This change also changed a lot of structures, function naming etc.
2948 Most important change was that SilcClientWindow object was
2949 renamed to SilcClientConnection in the client library. Created
2950 also new file lib/silcclient/ops.h. Also added new files
2951 silc/local_command.[ch] and silc/client_ops.[ch].
2953 All these changes were made to make it easier for user interface
2954 designers to create what ever user interface for the SILC client
2957 It is also expected that the server will be moved to lib
2958 directory as well and SILC Server Library will be created;
2959 sometimes in the future.
2961 * Removed Local commands from lib/silccore/silccommand.h as
2962 they are application specific and new client library does not
2963 handle any of those anymore.
2965 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2966 old client implementation in silc/.
2968 * Added support for callback functions in SILC_LOG_* macros.
2969 Application can now set its own callbacks that will be called
2970 instead of using the default functions that will always print
2971 the debug messages to stderr (or stdout). Also, debugging can
2972 now be disabled by setting silc_debug to FALSE and re-enabled by
2973 setting it to TRUE. Note, that logging will still work even
2974 if debugging is disabled.
2976 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2977 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2978 silc_log_reset_debug_callbacks.
2980 * To enable debugging in silc client one must give now -d
2981 option on command line.
2983 * Changed silc_schedule_init to automatically allocate task queues
2984 if they are not allocated before calling it.
2986 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Added GMP 3.1 into math library.
2990 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2993 a channel in SILC network. The packet is used by servers and
2994 routers to notify other routers that user has left a channel.
2995 This little feature was missing until now. Added the feature
2996 to protocol specification as well.
2998 Added functions: silc_server_send_remove_channel_user and
2999 silc_server_remove_channel_user into server.[ch].
3001 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3002 lib/silccore/silcpacket.h. However, they are not implemented
3005 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed joining to a channel and sending channel messages
3008 between server and router. The channel message sending should
3009 now work inside a cell.
3011 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Fixed the private message sending between server and router.
3014 The private message sending should now work inside a cell.
3016 * Added silc_server_replace_id into server.[ch] to replace
3017 existing ID in the SILC network.
3019 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3020 and silc_idlist_replace_server_id into idlist.[ch] in server.
3022 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Fixed the server to server connections. Server can again now
3025 connect to router. Router to router connections probably does
3028 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Added dynamic protocol registering support. Now protocols can
3031 registered and unregistered on the fly. Patch by cras.
3033 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added lib/contrib directory to hold routines that some platforms
3036 don't have but are needed by SILC.
3038 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3039 into lin/contrib to provide getopt() and getopt_long() for
3040 those who don't have it.
3042 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Added AWAY command to client. When away message is set and
3045 client receives a private message packet the client automatically
3046 replies to the sender with the away message.
3048 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3049 bug seemed to be the cause of recent problems when compiling
3052 * Added version detection support to SKE protocol specification
3053 and added the new changes to the SKE implementation as well.
3054 There were other minor changes in the SKE protocol as well.
3056 Many changes in lib/silcske/silcske.[ch] and in
3057 lib/silcske/payload.[ch].
3059 * Added ^U functionality, clear input line. Patch from cras.
3061 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Mainly small bugfixes on core library. Fixed some debugging
3064 logging and buffer overflow in silclog.c.
3066 * Updated config.sub and config.guess on the distribution tree.
3068 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Added command lagging support in server. Client may execute
3071 commands now only once in two seconds.
3073 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Optimized packet reception. MAC computation and checking is now
3076 also more optimized. A lot previously duplicated code is now
3077 used as generic by both client and server.
3079 * Fixed key pair generation in clientutil.c
3081 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Added into lib/silccore/silcbufutil.[ch] new function;
3084 silc_buffer_realloc.
3086 * Moved generic packet sending/encryption functions to
3087 lib/silccore/silcpacket.[ch] from client and server. Some
3088 rewriting of the functions.
3090 * Moved all generic packet reception/decryption functions to
3091 lib/silccore/silcpacket.[ch] from client and server. The
3092 packet processing is now much cleaner in both client and server.
3093 These were major changes in both client and server.
3095 * Created many common functions in server to do packet sending.
3096 Previously code were duplicated a lot, this has been removed
3099 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Rewrote major parts of the ID cache system. Don't know
3102 whether it is better now or not but at least the API is more
3105 * Major rewrite on ID cache stuff on client because of the ID
3106 cache API changes. Added idlist.c to client.
3108 * Also major rewrite on ID cache stuff on server as well.
3109 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3110 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3111 in hand, instead they are all put into the ID cache system now.
3112 All server_idlist_* routines uses ID cache now instead of
3113 traversing its own lists (those lists does not exist anymore).
3114 SilcIDList though still exists. Also, SilcXXXEntry's are
3117 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Finally made the SKE implementation compliant to the protocol
3120 specification. All mp integers are now binary encoded as
3121 opposed being HEX encoded.
3123 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3126 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3127 functions: silc_[encode/decode]_pem. Also added function
3128 silc_encode_pem_file to PEM encode with newlines ('\n') for
3131 * SILC public keys are now encoded either PEM or binary. Same
3132 option is for private keys as well. By default private keys
3133 are binary encoded and public keys PEM encoded. Silly HEX
3134 encoding were removed.
3136 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3137 function to create fingerprints.
3139 * Fixed a bug in SHA1; does not change the original data anymore.
3141 * Partly implemented INFO command on client and server side.
3142 Fixed CLEAR command. Changes to SERVER command; show current
3143 server(s) when giving command without arguments. Added
3144 VERSION command to client.
3146 * Added check to server that unregistered connections cannot
3147 execute commands (unless it is specificly allowed).
3149 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Fixed screen refresh.
3153 * Fixed channel joining bug from client. On some circumstances
3154 client tried to join to a channel it had already joined.
3156 * Added public key verification process into client's protocol.c.
3157 The client now verifies the public key from user and saves
3158 it into ~./silc/serverkeys/ directory.
3160 Added into: clientutil.[ch]: silc_client_verify_server_key.
3162 * Changed SKE protocol's silc_ske_initiator_finish function
3163 to accept callback function that verifies the received public
3164 key. Removed old silc_ske_verify_public_key function.
3166 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3169 silc_pkcs_private_key[_data]_set.
3171 * Made the password and public authentication more cleaner in
3172 server's protocol.c.
3174 * Removed historic and obsolete protocol `channel_auth' from
3175 both client and server.
3177 * Removed wrong way of sending command status messages from
3178 server to client in server's command.c. The old way violated
3179 protocol specification.
3181 Changes to silccore/silccommand.[ch]: removed
3182 silc_command_encode_status_payload -> not needed anymore,
3183 changed silc_command_encode_payload_va to accept extra
3184 argument on variable argument list. The argument type must
3185 now be provided to the function. Also, added new function:
3186 silc_command_encode_reply_payload_va which is same as
3187 normal command_encode_payload_va except command status type
3188 is provided as extra argument.
3190 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Added ~./silc directory handling. The directory includes the
3193 public and private keys for the client.
3195 Added silc_client_check_silc_dir, silc_client_create_identifier
3196 and silc_client_load_keys.
3198 * Implemented SILC protocol compliant public key. Added public
3199 and private key saving to and loading from files.
3201 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3202 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3203 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3204 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3205 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3207 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3208 silc_pkcs_load_[public/private]_key.
3210 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Added silc_server_get_route (route.[ch]) to get connection
3213 data for the fastest route for given ID.
3215 * Implemented INVITE command on client and server. The command
3216 were re-defined in the SILC Protocol Specification and the
3217 implementation now complies with the specification.
3219 * Implemented PING command on client and server.
3221 * Implemented NAMES command on client and server. The server side
3222 supports currently only normal server not router server yet.
3223 Some changes to NAMES definition in SILC protocol specification.
3225 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Implemented LEAVE command on client and server.
3229 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3230 again. This change was made to the protocol as well. Server
3231 should not violate the protocol specification anymore.
3233 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3236 was tested. SOCKS4 was not but should work anyway.
