3 * Added printing of error messages during SKE protocol from the
4 failure packet sent by server during SKE. Affected file
7 * Removed the client's failure_callback handling with timeout
8 and handle it immediately when received.
10 * The SKE library returned wrong type in SUCCESS and FAILURE
11 packets. They must be 32 bit MSB not 16 bit MSB.
13 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Ok, rewrote the logic of the re-key and now it seems to work.
16 I tested it on high traffic with frequent re-keys without
17 problems. Added hmac_receive (and renamed hmac to hmac_send)
18 in SilcClientConnection in lib/silcclient/client.h and
19 in SilcIDListData in silcd/idlist.h. Also, removed the
20 SilcPacketParserContext's cipher and hmac fields as they are
21 not needed anymore and actually caused some problems when
22 the ciphers and hmac's changed underneath the packet parser.
24 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * If re-key protocol is active then process the incoming packets
27 synchronously since we must assure that icoming packets encrypted
28 with the old key is processed before the new keys is set to
29 use. This is true other packets than for REKEY packets.
30 Affected file silcd/server.c. The same was done to client library
31 as well, affected file lib/silcclient/client.c.
33 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Fixed bug in client and server to accept the force send if
36 the packet is send from silc_[server/client]_packet_process
37 function. Otherwise the packets are never delivered, oops.
39 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Disable force sending of packets when REKEY protocol is active.
42 We must assure that no packet is sent directly when rekey is
43 performed. All packets must be sent through packet queue.
44 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
45 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
46 function is silc_[server/client]_packet_send_real to check
49 * Replaced the SIM paths from example config files to
50 /usr/local/modules. Also, make install creates now
51 /usr/local/silc/logs directory to hold all the SILC server
54 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Made the configure.in.pre work on Solaris. Patch by salo.
58 * Made all ciphers compatible with non-x86 machines. Defined
59 CBC mode macros into lib/silccrypt/ciphers_def.h.
61 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Fixed the make install.
65 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * When MAC computation fails the silc_packet_decrypt returned 0
68 even though it was supposed to return -1. Fixed this. The
69 affected file is lib/silccore/silcpacket.c.
71 * Do not replace the config files in /etc/silc (in make install)
72 if they already exist. Affected file ./Makefile.am.
74 * Do not send re-key packets immediately but through packet queue.
75 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
77 * Changed silc_net_check_host_by_sock to return FALSE if the
78 IP/DNS could not be resolved. Though, it returns the IP address
79 now even if it could not resolve it (but returns also FALSE).
80 Affected file lib/silcutil/silcnet.[ch].
82 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
84 * Added silc_pkcs_decode_identifier to decode the public key's
85 identifier. Affected file lib/silccrypt/silpkcs.[ch].
86 Added also silc_pkcs_free_identifier. Added also new context
87 SilcPublicKeyIdentifier.
89 * Added -S option to the silc client. It is used to dump the
90 contents of the specified public key file.
92 * Changed the PKCS api to return the public key length when
93 setting the public key.
95 * Fixed a fatal bug in the public and private key file loading.
96 Affected file lib/silccrypt/silcpkcs.c.
98 * Execute the packet parsing for client with zero (0) timeout
99 if the protocol is active. Affected file silcd/server.c.
101 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Made the key generation options to the silcd program. Added
104 -C option, equivalent to client's option.
106 * Added new [ServerKeys] config section to the server. It
107 configures the server's public and private key.
109 * Defined generic Public Key Payload into the protocol
110 specification to send specific type of public keys and
113 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
114 public key or certificate.
116 * Implemented the GETKEY command to the server and to the
117 client library and on user interface.
119 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Made preliminary `make install' work.
123 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
125 * Added SilcServerRekey context into silcd/idlist.h.
127 * Added the PFS support as defined in the specification to the
128 SKE protocol. Affected files lib/silcske/*.c.
130 * Added `ske_group' field to the SilcServerRekey context to hold
131 the number of the SKE group that is used with PFS in re-key.
132 Affected file silcd/idlist.h.
134 * Added PFS re-key support to the server. Affected file is
137 * Added silc_protocol_cancel to cancel execution of the next
138 state of the protocol. Affected file is
139 lib/silccore/silcprotocol.[ch].
141 * Added the re-key support with and without PFS to the client
142 library. Re-key is performed once in an hour, by default.
144 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
145 Added silc_client_rekey_callback and silc_client_rekey_final.
146 Affected files are lib/silcclient/protocol.[ch] and
147 lib/silcclient/client.[ch].
149 * Removed the `hmac_key' and `hmac_key_len' fields from the
150 SilcClientConnection structure; not needed. Affected file is
151 lib/silcclient/client.h.
155 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Do not ask whether user wants to use the negotiated private key
158 for private messages, just use it. Affected file is
159 silc/local_command.c.
161 * Added `send_enc_key' and `enc_key_len' fields to the
162 SilcIDListData structure since they are needed in the re-key
163 phase. Affected file is silcd/idlist.[ch].
165 * Implemented the simple re-key protocol into the server.
166 Affected files silcd/server.c and silcd/protocol.[ch]. The
167 re-key will be performed once in an hour, by default.
169 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
170 Added silc_server_rekey, silc_server_rekey_callback and
171 silc_server_rekey_final.
173 * Removed Tunneled flag from the protocol. Updated the code
174 and the specifications.
176 * Adde `pfs' field to the SilcIDListData to indicate whether
177 the PFS is to be performed in the re-key. Affected file is
180 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
183 int64 of at least the xintXX size. If void * is less that 4
184 bytes uint32 * will be used. Defined bool as boolean.
186 * Changed _ALL_ unsigned long and unsigned int to uint32,
187 unsgined short to uint16 in the source tree.
189 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
190 not handle clients that has entry->data.registered == FALSE.
191 They are not in the network anymore. Affected file is
194 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Implemented the sending of the SERVER_SIGNOFF notify in the
197 server. Affected file is silcd/server.c.
199 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
200 Added also silc_notify_payload_encode_args into the
201 lib/silccore/silcnotify.[ch].
203 * Implemented ther SERVER_SIGNOFF notify handling in the server.
204 Affected file silcd/packet_receive.c.
206 * Implemented the SERVER_SIGNOFF notify handling in the client
207 library. Affected file lib/silcclient/client_notify.c. Also,
208 implemnted the printing of the SERVER_SIGNOFF info to the
209 application. Affected file silc/client_ops.c.
211 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
212 if the deleting was successful. Affected file silcd/idlist.[ch].
214 * Added support for public key authentication in the connection
215 authentication protocol in the client library. Affected file
216 lib/silcclient/protocol.c.
218 * Changed the server's silc_idlist_get_clients_by_* interface
219 to support already allocated array so that new entries may be
220 added to pre-allocated array. Affected file silcd/idlist.[ch].
221 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
224 * All command reply functions in the server now calls the
225 pending command callback even if error occured. This way the
226 error will be delivered to the client as well. Affected files
227 silcd/command.c and silcd/command_reply.c.
229 * Fixed INFO command to return local server's info if no server
230 was provided. Affected file lib/silcclient/command.c.
232 * Removed RESTART command for good. Updated the code and the
235 * Rewrote parts of the task system. It is a bit simpler now.
236 Removed unsued task priorities. The affected files are
237 lib/silcutil/silctask.[ch].
239 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * Moved the USERS printing from the library to the application.
242 Affected files lib/silcclient/command.c and silc/client_ops.c.
244 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Added channel key re-key support. The re-key is perfomed
249 only by the router and is done once in an hour. Added `rekey'
250 field to the SilcChannelEntry in the server. Affected files
251 silcd/server.c and silcd/idlist.h.
253 * Added silc_task_unregister_by_context into the file
254 lib/silcutil/silctask.[ch].
256 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Added SILC_UMODE_GONE mode to indicate when the client is not
259 present in the SILC network. Added also support to the local
260 command AWAY that will set this mode. Added support of showing
261 "xxx is gone" in WHOIS command. The USERS command shows the
264 * Fixed setting server and router operator privileges in the
265 server's UMODE command. Affected file silcd/command.c.
267 * Merged the SKE KE1 and KE2 payloads into one payload. The
268 new KE payload is equivalent to the old KE2 payload.
270 Cleaned up the SKE Start Payload parsing. It now uses the
271 simple buffer unformatting to do the parsing. A lot faster
274 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
275 to the SKE that is used to indicate whether both of the SKE
276 parties should perform authentication. By default only the
277 responder performs authentication. By setting this flag also
278 the initiator must do authentication. By default it is unset
279 since in normal SKE case, client to server connection, only
280 the responder should do authentication. When doing SKE between
281 two clients both should perform authentication. Updated the
282 code and the protocol specs.
284 * A little fix to IDENTIFY command in the server. Search the
285 client first by hash not nickname. Affected file is
288 * Fixed the silc_client_close_connection to support closing
289 the client to client connections wihtout deleting too much
290 data. Affected file lib/silcclient/client.c.
292 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
293 are received if protocol used to be active but is not anymore
294 the application would crash due to NULL pointer dereference.
295 Affected files silcd/server.c and lib/silcclient/client.c.
297 * Added `hash' field to the SilcClientConnection to include
298 the hash function negotiated in the SKE protocol.
300 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
301 to set the channel founder authentication data. A client can
302 claim the founder rights later by providing the authentication
303 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
304 This way the channel founder can regain the channel founder
305 privileges even it is left the channel. This works only on
306 local server and the client must be connected to the same
307 server to be able to regain the founder rights. Updated the
308 protocol specs accordingly.
310 Added support to the CMODE command in the client to set the
311 founder auth data. Read the README to see how to set it.
313 Added support to the CUMODE command to claim the founder
314 rights. Read the README to see how to do it.
316 Added support for the founder authentication to the Channel
317 Entry in the server. Affected file silcd/idlist.h.
319 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
320 server's CMODE command. Affected file silcd/command.c.
322 * Added the following new functions into lib/silccore/silcauth.[ch]:
323 silc_auth_get_method and silc_auth_get_data.
325 * The server now saves the remote hosts public key to the
326 SilcIDListData pointer. Affected file silcd/protocol.c.
328 * The normal server now does not remove the channel entry from
329 the cache if the founder authentication data is set. It used
330 to remove it if the founder was the last one on the channel on
331 the server and left the channel. The auth data is saved and
332 if the channel is re-joined later the old entry is used with
333 the old auth data. Affected files silcd/command_reply.c and
336 * Removed the `pkcs' field from the SilcIDListData structure
337 in the server; it is not used. Affected file silcd/idlist.h.
339 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Fixed packet processing on slow links. Partial packets were
342 never re-processed because the incoming data buffer was cleared
343 by the application. Application must not directly clear the
344 sock->inbuf, the packet processing routines handle it. Fixed
345 this in client library and in server.
347 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Fixed the WHOIS and IDENTIFY send reply function to really
350 check whether to send list or just one entry. Affected file
353 * Cleaned up the LEAVE command's channel key distribution. The
354 affected file silcd/command.c.
356 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
357 can enforce the channel mode as well. In that case the ID
358 includes the ID of the server. The code now enforces the
359 mode change if the router have different mode than the server.
361 * The notify client operation with CMODE_CHANGE notify can now
362 return NULL client_entry pointer if the CMODE was not changed
363 by client. Application must check for this.
365 * Added <Server ID> argument to INFO command to support server
366 info fetching by Server ID.
368 * Added silc_server_announce_get_channel_users to get assembled
369 packets of channel users of the specified channel. Affected
370 file silcd/server.[ch].
372 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
373 was freed underneath the ID Cache.
375 * Re-announce clients when the server received CHANNEL_CHANGE
376 notify from the router. Affected file silcd/packet_send.c.
378 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
380 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
381 crashed since it did not handle the fact that there is no cipher
382 called "3" and didn't check the error condition. Now fixed.
384 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
385 flag. It can be used to send message requests.
387 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Implemented the RESTART command in the client.
391 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
392 notice type messages. Added notice printing to the user
395 * The channel keys are not re-generated if the channel's mode
396 is PRIVKEY, ie private key on the channel exists. Affected
397 files silcd/server.c and silcd/command.c.
399 * Fixed a little bug in channel message delivery when channel
400 private keys are set in the server. Affected file is
403 * Changed the setting on channel->on_channel = TRUE from the
404 silc_client_save_channel_key to the JOIN command reply. The
405 key payload is not received if the private channel key is set.
406 Affected file lib/silcclient/command_reply.c and the
407 lib/silcclient/client_channel.c.
409 * When the CMODE_CHANGE notify is sent and the channel private
410 key mode is removed the channel key must be re-generated in
411 other cells as well. Added this support for the router in the
412 silcd/packet_receive.c.
414 * Added new local command NOTICE to send notice message on
415 channel. Affected file silc/local_command.[ch].
417 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Added new local command ME to the client. It is used to send
420 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
421 some action. Affected file silc/local_command.[ch].
423 * Changed channel_message and private_message client operations
424 to deliver the message flags to the application. Added also
425 the `flags' arguments to the silc_client_send_channel_message
426 and silc_client_send_private_message functions. Affected file
429 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
431 * Redefined the Private Message Payload to support private message
432 keys and to support the new private message flags. Updated
433 the protocol specs. Flags makes it possible to have for example
436 * Added new type SilcPrivateMessagePayload and defined an API
437 for it in the lib/silcclient/silcprivate.[ch].
439 * Tested private message private keys successfully. Tested the
440 private message key set, unset and list commands with the new
443 * Redefined the Channel Message Payload to include the channel
444 message flags (equal with private message flags) to support
445 for example CTCP style messages.
447 * Defined some of the message (for channel and private message)
448 flags. Updated the protocol specs and added the flags to the
449 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
451 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Added SilcKeyAgreementStatus type to the key agreement routines
454 to indicate the current status and error if one occured.
455 The status types are defined in the lib/silcclient/silcapi.h.
457 * Added new local command KEY that is used to set and unset private
458 keys for channels, set and unset private keys for private messages
459 with remote clients and to send key agreement requests and
460 negotiate the key agreement protocol with remote client. The
461 key agreement is supported only to negotiate private message keys,
462 it currently cannot be used to negotiate private keys for channels,
463 as it is not convenient for that purpose.
465 * Fixed a minor pending callback setting bug in the function
466 silc_client_get_client_by_id_resolve, now the function works.
467 Affected file lib/silcclient/idlist.c.
469 * Added function silc_net_get_local_port to get local bound
470 port by socket. Added to lib/silcutil/silcnet.[ch].
472 * Added `sockets' and `sockets_count' fields to the SilcClient
473 object. They hold the sockets of the listenning sockets in
474 the client. Listenning sockets may be for example the key
475 agreement server. Affected file lib/silcclient/client.[ch].
476 Added functions the silc_client_add_socket and the
477 silc_client_del_socket. They are exported to the application
480 * Added ~./silc/clientkeys to support other client's public keys.
482 * Renamed verify_server_key client operation to verify_public_key
483 and added one argument to indicate the type of the connection
484 (server, client etc.).
486 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
488 * Added silc_server_connection_auth_request to handle the
489 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
490 silcd/packet_receive.[ch].
492 * Added silc_server_send_connection_auth_request into the
493 silcd/packet_send.c to send the connection auth request packet.
495 * Cleaned up the silcd/protocol.c a bit and fixed some memory
498 * Fixed the public key authentication in responder side in the
499 server. The `auth_data' pointer includes the SilcPublicKey
500 not the path to the public key. Affected file silcd/protocol.c.
502 * Implemented the public key authentication in the initiator side
503 in the server. Affected file silcd/protocol.c.
505 * Removed the [RedirectClient] config section from the server
506 configuration. Is not needed and I don't want to implement it.
508 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Cleaned up the CMODE command in the server. It now works
511 correctly and supports all the modes defined in the protocol.
512 Affected file is silcd/command.c.
514 * Added `hmac_name' field to the SilcChannelEntry in the server
515 to hold the default HMAC of the channel. It can be set when
516 creating the channel (with JOIN command). Affected files
519 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
520 type to indicate the change of the current cipher and hmac
521 on the channel. Client can safely ignore the <cipher> argument
522 (if it chooses to do so) since the CHANNEL_KEY packet will
523 force the channel key change anyway. The <hmac> argument is
524 important since the client is responsible of setting the new
525 HMAC and the hmac key into use.
527 * Fixed the CMODE command in the client library as well.
529 * Tested CMODE command in router environment successfully.
531 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Show the version of the remote client (or server) when connecting
534 to the server. It is logged to the log file. Affected file
537 * Fixed the KILLED notify handling in the client library. The
538 client must be removed from all channels when receiving the
541 Also, do not remove the client entry when giving the KILL
542 command but when the KILLED notify is received.
544 * Removed silc_idlist_find_client_by_nickname from the server.
545 Not needed anymore. Affected files silcd/idlist.[ch].
547 * Implemented the CHANNEL_CHANGE notify type handling to the
548 server. Affected file silcd/server.c.
552 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Added silc_server_send_notify_invite to send the INVITE
555 notify between routers.
557 * Implemented the INVITE command correctly to the server.
559 * Implemented the INVITE notify type handling in the server.
561 * Implemented the INVITE command to the client library and on the
564 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Added function silc_server_get_client_resolve to find the
567 client entry by ID from all ID lists and then resolve it
568 (using WHOIS) if it cannot be found. Affected file is
571 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
573 * Implemented the BAN command to the client library.
575 * The JOIN command in the server now checks the invite list
578 * Changed the silc_command_reply_payload_encode_va and the
579 silc_command_payload_encode_va to support that if argument is
580 NULL it ignores and checks the next argument. Affected file
581 lib/silccore/silccommand.c.
583 * Added silc_server_send_notify_ban to send the BAN notify
584 type between routers.
586 * Chaned the silc_notify_payload_encode to support that if
587 argument is NULL it ignores and checks the next argument.
588 Affected file lib/silccore/silcnotify.c.
590 * Tested ban lists in router environment successfully.
592 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Implemented BAN command to the server, in silcd/command.[ch].
596 * Removed the BAN and INVITE_LIST modes from the CMODE command
599 * Added function silc_string_match to regex match two strings.
600 Affected files lib/silcutil/silcutil.[ch].
602 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Redefined parts of the SilcChannelEntry in the server to support
605 the new ban and invite lists.
607 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Redefined the INVITE command. The same command can be used to
610 invite individuals to the channel but also to manage the invite
611 list of the channel (to add to and remove from the invite list).
612 Updated the protocol specs.
614 * Added new command SILC_COMMAND_BAN that can be used to manage
615 the ban list of the channel. Updated the protocol specs.
617 * Removed the channel modes: the SILC_CMODE_BAN and the
618 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
619 in the CMODE command. The equivalent features are now available
620 using INVITE and BAN commands. Updated the protocol specs.
622 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
623 in the network about change in the current ban list. The notify
624 type is not used by the client.
626 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
627 support the invite lists.
629 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added new function silc_string_regexify that converts string
632 including wildcard characters into regex string that can
633 be used by the GNU regex library. Added into the file
634 lib/silcutil/silcutil.[ch].
636 Added silc_string_regex_combine to combine to regex strings
637 into one so that they can be used as one regex string by
638 the GNU regex library. Added into the file
639 lib/silcutil/silcutil.[ch].
641 Added silc_string_regex_match to match two strings. It returns
642 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
644 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Imported GNU regex to the soruce tree into lib/contrib.
647 Fixed some compiler warning from the regex.c.
649 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed MOTD command in the server to work in router environment.
653 * Fixed the MOTD command in the client library to support
654 the server argument in the command.
656 * Added `nickname_len' argument to the silc_idlist_add_client
657 in the server, as the `nickname' argument may be binary data
660 * Added silc_idlist_get_channels to return all channels from
663 * Implemented LIST command to the server. Affected file is
666 * Implemented the LIST command to the client library and on the
669 * Added [<user count>] argument to the LIST command reply.
670 With private channels the user count is not shown.
672 * Updated TODO and README.
674 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * The client entry's data.registered must be TRUE even with
677 global client entry on global client list. The data.registered
678 is used to check whether the client is anymore in the network,
679 for example with WHOWAS command so it must be valid.
681 * Fixed the WHOWAS command in the server. It now actually works
682 in router environment. Added function into silcd/command_reply.c
683 silc_server_command_reply_whowas_save.
685 * Added silc_idlist_purge function to the silcd/idlist.c
686 to periodically purge the ID Cache.
688 * Fixed INFO command in the server. It works now in router
689 environment. Added <server name> argument to the INFO command
690 reply. Updated the protocol specs.
692 * Fixed minor bug in silc_idcache_purge to not purge if the
693 expire value is zero.
695 * Fixed various bugs in WHOIS and IDENTIFY command handling as
696 they were buggy because of the WHOWAS information.
698 * Fixed local command MSG to handle the async resolving of
699 the remote client properly. It used to fail the first MSG.
700 Affected file silc/local_command.c.
702 * Added `data_len' field to SilcIDCache context.
704 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Update TODO. Todo in commands in the server.
708 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
710 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
711 used by routers as broadcast packet to inform other routers
712 about the changed user mode.
714 Implemented the notify handling in the server. Affected file is
715 silcd/packet_receive.c. Added the function
716 silc_server_send_notify_umode to the silcd/packet_send.[ch].
718 * Added new generic Channel Payload and deprecated the New Channel
719 Payload. The New Channel Payload is now the generic Channel
722 * Added new argument `mode' to the silc_server_send_new_channel
723 as it is required in the Channel Payload now.
725 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
726 and created a new and real SilChannelPayload to represent the
727 new generic Channel Payload. Implemented the encode/decode
728 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
730 * Added silc_server_get_client_channel_list to return the list
731 of channels the client has joined for WHOIS command reply.
732 Affected file silcd/server.[ch].
734 * Implemented the channel list sending in the WHOIS command reply
735 in server and in the client.
737 Implemented the channel list displaying on the user interface
738 as well. Affected file silc/client_ops.c.
740 * Added silc_channel_payload_parse_list to parse list of Channel
741 Payloads. It returns SilcDList list of SilcChannelPayloads.
742 Client for example can use this function to parse the list of
743 channels it receives in the WHOIS command reply. The caller
744 must free the list by calling silc_channel_payload_list_free.
745 Affected files lib/silccore/silcchannel.[ch].
747 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added one new argument <user mode> to the WHOIS command reply
750 to return the mode of the user in SILC. Updated the protocol
753 Implemented it to the server and client.
755 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Fixed the mode printing on the user interface on joining.
758 Affected file silc/client_ops.c.
760 * Implemented the UMODE command and user modes in general to the
761 client library and to the user interface.
763 * Implemented the UMODE command to the server.
765 * The server now sends UNKNOWN_COMMAND error status if client sends
766 unknown command. Affected file silcd/command.c.
768 * All server commands now handle the command identifier the right
769 way when sending the command reply to the client. The client can
770 use to identify the command replies with the identifier.
772 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Added silc_server_get_client_route to resolve the route to
775 the client indicated by the client ID. Affected file is
778 * Added silc_server_relay_packet as general function to relay
779 packet to arbitrary destination. This deprecates functions
780 like _send_private_message_key, _relay_notify etc. Affected
781 file is silcd/packet_send.[ch].
783 Removed silc_server_send_key_agreement,
784 silc_server_send_private_message_key and
785 silc_server_packet_relay_notify functions from the file
786 silcd/packet_send.[ch].
790 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
791 server. Affected file silcd/packet_receive.[ch].
793 * Implemented the KILL command to the client. Implemented the
794 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
795 Affected files lib/silcclient/command[_reply].c and
796 lib/silcclient/client_notify.c. Implemented the KILL notify
797 printing in the user inteface.
799 * Fixed a lot silc_parse_nick memory leaks from the client
800 library in the file lib/silcclient/command.c.
802 * Changed the silc_server_send_notify_on_channels's `sender'
803 argument from SilcSocketConnection to SilcClientEntry to
804 check the sender as entry and not as connection object and not
805 to send to the client provided as argument. The affected file
806 is silcd/packet_send.[ch].
808 * The notify packets that are destined directly to the client used
809 to not to be processed by the server. Now changed that and the
810 server processes all notify packets. After relaying the packet
811 to the client the notify packet is processed in the server.
813 * The silc_server_free_client_data now checks whether there is
814 pending outgoing traffic for the client and purges the data to
815 the network before removing the client entry.
817 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
820 an client is killed from the SILC Network. Updated the protocol
823 Added new function silc_server_send_notify_killed to the
824 silcd/packet_send.[ch].
826 * Added function silc_server_packet_relay_notify to relay notify
827 packets that are destined directly to a client. In this case
828 the server does not process the notify packets but merely relays
829 it to the client. Affected file silcd/packet_send.[ch].
831 Added also silc_server_packet_process_relay_notify to check
832 whereto relay the notify. Affected file is
833 silcd/packet_receive.[ch].
835 * Implemented the KILL command to the server.
839 * Added the backup schema desgined last fall to the protocol
840 specs for everyone to see. The specification is in the
841 *-spec-xx.txt draft and the packet type definitions for the
842 backup routers is in *-pp-xx.txt draft. Thusly, added also
843 new packet type SILC_PACKET_CELL_ROUTERS.
845 * A big security problem in the implementation discovered. The
846 signoff of an client did not cause new channel key generation
847 which it of course should've done. The channel keys must be
848 always re-generated when client leaves (or signoffs) the channel.
849 The silc_server_remove_from_channels funtion now handles
850 the channel key re-generation.
852 * Added `sender' argument to the silc_server_send_notify_on_channels
853 to not to send the client provided as argument. Affected file
854 silcd/packet_send.[ch].
856 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Implemented OPER and SILCOPER commands into the server and
861 * Added silc_auth_verify and silc_auth_verify_data to verify
862 the authentication directly from the authentication payload.
863 It supports verifying both passphrase and public key based
864 authentication. Affected file lib/silccore/silcauth.[ch].
866 * Added `hash' field to the SilcIDListData structure. It is the
867 hash negotiated in the SKE protocol. Affected file is
870 * Slight redesigning of the SilcAuthPayload handling routines.
871 Do not send SilcPKCS but SilcPublicKey as argument.
873 * Implemented the public key authentication support to the
874 serverconfig. The public key is loaded from the provided path
875 and saved as authentication data to void * pointer. Thus,
876 changed the unsigned char *auth_data to void *auth_data;
878 * Fixed SHUTDOWN command to send the reply before the server
879 is shutdown. :) Affected file silcd/command.c.
881 * Fixed fatal bug in CONNECT command. The hostname was invalid
882 memory and server crashed. Affected file silcd/command.c.
884 * Fixed fatal bug in CLOSE command. The server_entry became
885 invalid but was referenced later in the command. Affected file
888 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Fixed fatal bug in failure packet handling. Server ignored
891 the failure and thus crashed when it came.
895 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
898 that the command may be executed only once in (about) 2 seconds.
899 The old SILC_CF_LAG flag is same but allows command bursts up
900 to five before limiting.
902 Added the support for CF_LAG and CF_LAG_STRICT flags to the
903 server code. Various commands now includes the CF_LAG_STRICT
904 flag to disallow any kind of miss-use of the command.
906 * Fixed the silc_buffer_unformat to not to allocate any data
907 if the length of the data is zero. It used to allocate the
908 length + 1. Affected file lib/silcutil/silcbuffmt.c.
910 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Changed the format of AdminConnection configuration section
913 in the server. Added username of the admin to the format.
914 Affected files silcd/serverconfig.[ch].
916 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
917 to return admin configuration data by host, username and/or
920 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Implemented WHOWAS command to the server. Added the functions:
924 silc_server_command_whowas_parse,
925 silc_server_command_whowas_send_reply,
926 silc_server_command_whowas_from_client and
927 silc_server_command_whowas_from_server
929 * Added <Client ID> argument to the WHOWAS command reply. Updated
930 the protocol specs accordingly.
932 * Implemented WHOWAS command and command_reply to the client
935 Implemented the WHOWAS printing on the user interface.
937 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Added new argument to the WHOWAS command reply, the real name.
940 It is an optional argument. Updated the protocol specs.
942 * Added SilcIDCacheDestructor callback that is registered when
943 the SilcIDCache is allocated. The callback is called when
944 an cache entry in the ID Cache expires, or is purged from the
945 cache. Added into lib/silccore/idcache.[ch].
947 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
948 to destruct the client entries when the cache entry expires.
949 Other ID Cache's in server and in the client library ignores
952 * If the ID Cache entry's `expire' field is zero then the entry
953 never expires. Added boolean `expire' argument to the
954 silc_idcache_add function in the lib/silccore/idcache.[ch].
955 If it is TRUE the default expiry value is used.
957 * Added silc_server_free_client_data_timeout that is registered
958 when client disconnects. By default for 5 minutes we preserve
959 the client entry for history - for WHOWAS command.
961 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Added support to the server to enforce that commands are not
964 executed more than once in 2 seconds. If server receives
965 commands from client more frequently, timeout is registered
966 to process the commands. Affected file silcd/command.c.
967 Added new function silc_server_command_process_timeout.
969 * Changed NICK_NOTIFY handling in client library to check that
970 if the client's nickname was changed, so there is no need to
971 resolve anything from the server.
973 * Removed error printing from the WHOIS and IDENTIFY commands.
974 If error occurs then it is ignored silently in the client library.
975 The application, however, may map the received error to
976 human readable error string. The application currently maps
977 the NO_SUCH_NICKNAME error to string.
979 * Made the command status message public to the application. Moved
980 them from lib/silcclient/command_reply.c to
981 lib/silcclient/command_reply.h. The application can map the
982 received command status to the string with the
983 silc_client_command_status_message function.
985 * Added check to the server to check that client's ID is same
986 as the Source ID in the packet the client sent. They must
989 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Added dist-bzip hook to the Makefile.am to make bzip2
992 compressed distributions.
994 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Server now enforces the maximum length for the nickname and
997 the channel as protocol specification dictates. 128 bytes for
998 nickname and 256 bytes for channel name.
1000 * Moved the WHOIS printing to the application. The client libary
1001 does not print out the WHOIS information anymore, the application
1002 must do it. Renamed silc_client_command_reply_whois_print to
1003 the silc_client_command_reply_whois_save.
1005 The client's idle time is also sent to the application now, and
1006 the idle is shown on screen.
1008 * Added silc_client_command_reply_identify_save to save the
1009 received IDENTIFY entries.
1011 * Do not check for channel private keys in message sending and
1012 reception if the channel does not have the PRIVKEY mode set.
1013 Affected file lib/silclient/client_channel.c.
1015 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1018 just surfaced after chaning the JOIN procedure.
1020 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Added silc_client_get_clients_by_list to get client entries
1023 from Client ID list, that is returned for example by JOIN
1024 and USERS command replies. The application should use this
1025 function for example when JOIN command reply is received to
1026 resolve the clients already on the channel (library does not
1027 do that anymore as USERS command reply is not used in the JOIN
1028 procedure anymore). Affected files lib/silcclient/silcapi.h and
1029 lib/silcclient/idlist.c.
1031 * JOIN command reply and USERS command reply returns now SilcBuffer
1032 pointers instead of unsigned char pointers when returning
1033 the client list and mode list.
1035 * Added <Client ID> argument to the JOIN command reply, mainly
1036 for the server to identify for which client the command was
1037 originally sent. Updated protocol specs accordingly.
1039 * Added SilcDlist private_key pointer to the SilcChannelEntry
1040 in the client to support the channel private keys. Affected
1041 file is lib/silcclient/idlist.h.
1043 * Added SilcChannelPrivateKey argument to the function
1044 silc_client_send_channel_message so that application can choose
1045 to use specific private ke if it wants to. If it is not provided,
1046 the normal channel key is used, unless private keys are set.
1047 In this case the first (key that was added first) is used
1048 as the encryption key.
1050 * Implemented the support for channel private key handling.
1051 Implemented the following functions:
1053 silc_client_add_channel_private_key,
1054 silc_client_del_channel_private_keys,
1055 silc_client_del_channel_private_key,
1056 silc_client_list_channel_private_keys and
1057 silc_client_free_channel_private_keys
1059 Affected file lib/silcclient/client_channel.c.
1061 * Added the support for the private keys in the channel message
1062 sending and encryption and in the message reception and
1063 decryption. Affected funtions are
1064 silc_client_send_channel_message and silc_client_channel_message.
1066 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Added SKE's key verify callback to the client library's
1069 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1071 * Removed the statement that server (or router) must send USERS
1072 command reply when joining to the channel so that the client
1073 knows who are on the channel. Instead, the client list and
1074 client's mode list is now sent in the JOIN command reply to the
1075 client who joined channel. This is better solution.
1077 * Added function silc_server_get_users_on_channel and function
1078 silc_server_save_users_on_channel to the silcd/server.[ch].
1080 * Removed function silc_server_command_send_users from the
1083 * Do not show topic on the client library anymore. The topic is
1084 sent in the command reply notify to the application and the
1085 application must show the topic now.
1087 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Added client searching by nickname hash into the IDENTIFY and
1090 WHOIS commands in the server as they were clearly missing from
1091 them. Affected file is silcd/command.c.
1093 * Fixed a bug in private message receiving in the client library.
1094 The remote ID was freed and it wasn't supposed, now it is
1097 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Minor fix to the channel payload; allocate the data area, as it
1100 needs to be of specific length.
1102 * If the key agreement port is zero then the operating
1103 system will define the bound port. Affected files are
1104 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1106 * Added new function silc_channel_payload_decrypt into the file
1107 lib/silccore/silcchannel.[ch].
1109 * Moved the channel message etc, check from silc_packet_decrypt
1110 to applications. The library calls now a generic
1111 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1112 when the packet is either normal or special. This was done to
1113 allow more wide range of checking that was not allowed when
1114 the code was in library. Now applications can do virtually any
1115 checks to the packet and return to the library the decision how
1116 the packet should be processed. Affected files are
1117 lib/silccore/silcpacket.[ch].
1119 Added silc_server_packet_decrypt_check to the server and
1120 silc_client_packet_decrypt_check to the client library.
1122 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1123 to send with specified source and destination information.
1125 * Channel message delivery between routers was broken after the
1126 channel key distribution was fixed earlier. The channel key
1127 was used be to distributed to other routers as well which is not
1128 allowed by the protocol. Now this is fixed and channel keys
1129 really are cell specific and the channel message delivery between
1130 routers comply with the protocol specification.
1132 * Fixed various commands in server to check also the global list
1133 for the channel entry and not just the local list. The affected
1134 file silcd/command.c.
1136 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Added assert()s to buffer formatting and unformatting routines
1139 to assert (if --enable-debug) when error occurs. Affected
1140 file: lib/silcutil/silcbuffmt.c.
1142 * Changed to auto-reconnect to check whether the remote host is
1143 router and register the re-connect timeout if it is. It used
1144 to check that whether we are normal server, but router must do
1145 auto-reconnect with another router as well. Affected file
1148 * Removed the [<key len>] option from CMODE command as the cipher
1149 name decides the key length, nowadays. See the defined ciphers
1150 from the protocol specification.
1152 * Added [<hmac>] option to the CMODE command to define the HMAC
1153 for the channel. Added SILC_CMODE_HMAC channel mode.
1155 * Added [<hmac>] option for the JOIN command so that user can
1156 select which HMAC is used to compute the MACs of the channel
1159 * Added Hmac field to the Channel Message Payload. The integrity
1160 of plaintext channel messages are now protected by computing
1161 MAC of the message and attaching the MAC to the payload. The
1162 MAC is encrypted. Now, it is clear that this causes some
1163 overhead to the size of the packet but rationale for this is that
1164 now the receiver can verify whether the channel message decrypted
1165 correctly and also when private keys are set for the channel the
1166 receiver can decrypt the packet with several keys and check from
1167 the MAC which key decrypted the message correctly.
1169 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1170 lib/silccrypt/silccipher.[ch].
1172 * Added silc_hash_len to return the digest length into the
1173 lib/silcrypt/silchash.[ch].
1175 * Rewrote parts of Silc Channel Payload interface in the
1176 lib/silccore/silcchannel.[ch]. The encode function now also
1177 encrypts the packet and parse function decrypts it.
1179 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Fixed a minor formatting bug in the SKE's key material processing.
1182 It actually might have processed the keys wrong way resulting
1185 * Redefined the mandatory HMAC algorithms and added new algorithms.
1186 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1187 and hmac-md5 truncated to 96 bits. The mandatory is now
1188 hmac-sha1-96. Rest are optional (including the one that used
1189 to be mandatory). Rationale for this is that the truncated HMAC
1190 length is sufficient from security point of view and can actually
1191 make the attack against the HMAC harder. Also, the truncated
1192 HMAC causes less overhead to the packets. See the RFC2104 for
1195 * Added new [hmac] configuration section. The SKE used to use
1196 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1197 is of course wrong. The official names that must be proposed in
1198 the SKE are the ones defined in the protocol specification
1199 (hmac-sha1-96 for example). The user can configure any hmac
1200 using any hash function configured in the [hash] section. At
1201 least, the mandatory must be configured.
1203 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1205 * Added HMAC list to the SKE proposal list. It has now both
1206 hash algorithm list and HMAC list. This makes the protocol
1207 incompatible with previous versions. The SKE now seems to work
1208 the way it is supposed to work, for the first time actually.
1210 * Defined plain Hash algorithms to the protocol specification.
1213 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Implemented support for key agreement packets into the server.
1216 Added functions silc_server_key_agreement and
1217 silc_server_send_key_agreement. Other than these functions,
1218 server has nothing to do with this packet.
1220 * Added support for private message key packets into the server.
1221 Added functions silc_server_private_message_key and
1222 silc_server_send_private_message_key.
1226 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1227 called in the protocol's final callback instead in the END
1228 protocol state. This makes a little more sense and in the same
1229 time in client we can use the same protocol routines for normal
1230 key exchange and to key agreement packet handling as well.
1232 * Added to both client's and server's KE protocol context the
1233 SilcSKEKeyMaterial pointer to save the key material. We will
1234 bring the key material to the protocol's final callback by doing
1235 this. The final callback must free the key material.
1237 * Added SKE's packet_send callback into client's KE protocol
1238 context so that the caller can choose what packet sending function
1239 is used. This way we can use different packet sending when
1240 doing normal SKE when doing key agreement packet handling (in
1241 the key agreement packet handling we do not want to encrypt
1244 * Implemented the responder side of the key agreement routines
1245 in the client. The client can now bind to specified port and
1246 accept incoming key negotiation. The key material is passed
1247 to the application after the protocol is over.
1249 * Implemented the processing of incoming Key Agreement packet
1250 in the client. Added function silc_client_key_agreement to
1253 * Implemented the intiator side of the key agreement routines
1254 in the client. The client can now initiate key agreement with
1255 another remote client. The key material is passed to the
1256 application after the protocol is over.
1258 * Created client_keyagr.c to include all the key agreement
1261 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1262 SILC_TASK_CALLBACK except that it is not static.
1264 * Created client_notify.c and moved the Notify packet handling
1265 from the client.[ch] into that file.
1267 * Created client_prvmsg.c and moved all private message and
1268 private message key routines from the client.[ch] into that file.
1270 * Create client_channel.c and moved all channel message and
1271 channel private key routines from the client.[ch] into that file.
1273 * Changed silc_client_get_client_by_id_resolve to resolve with
1274 WHOIS command instead of IDENTIFY command, in the file
1275 lib/silclient/idlist.c.
1277 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Implemented the SKE's responder side to the Client library.
1281 * When FAILURE is received to the protocol do not trust it
1282 blindly. Register a timeout to wait whether the remote closes
1283 the connection as it should do it, only after that process the
1284 actual failure. This was changed to both client and server.
1286 * Added client_internal.h to include some of the structures
1287 there instead of client.h in lib/silcclient/.
1289 * Added function silc_task_unregister_by_callback to unregister
1290 timeouts by the callback function.
1292 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Some "Incomplete WHOIS info" errors has been appearing on the
1295 log files. Took away the entry->userinfo check from WHOIS
1296 reply sending. The entry->userinfo is now " " if client did not
1297 provide one. I thought this was fixed earlier but something
1298 is wrong still. Let's see if the error still appears.
1300 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Fixed a minor bug in the login when the channel key is
1303 re-generated in the server. It used to generate the key in
1304 wrong order and thus caused problems in the channel traffic.
1306 * Fixed a minor bug in channel key distsribution after
1307 KICK command. The key was not sent to the router even though
1310 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Added silc_ske_process_key_material_data as generic routine
1313 to process any key material as the SILC protocol dictates. The
1314 function is used by the actual SKE library but can be used by
1315 applications as well. This relates to the private message keys
1316 and the channel private keys since they must be processed the
1317 same way the normal SILC session keys. The protocol dictates
1318 this. Affected files: lib/silcske/silcske.[ch].
1320 Added also silc_ske_free_key_material to free the
1321 SilcSKEKeyMaterial structure.
1323 * Defined silc_cipher_set_key function to set the key for
1324 cipher without using the object's method function. The affected
1325 files: lib/silccrypt/silccipher.[ch].
1327 * Implemented silc silc_client_add_private_message_key,
1328 silc_client_add_private_message_key_ske,
1329 silc_client_del_private_message_key,
1330 silc_client_list_private_message_keys and
1331 silc_client_free_private_message_keys functions in the
1334 Added functions silc_client_send_private_message_key to send
1335 the Private Message Key payload and silc_client_private_message_key
1336 to handle incoming Private Message Key payload.
1338 * Added Cipher field to the Private Message Key payload to set
1339 the cipher to be used. If ignored, the default cipher defined
1340 in the SILC protocol (aes-256-cbc) is used.
1342 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Removed lib/silcclient/ops.h file.
1346 Redefined parts of the SILC Client Library API. Created new
1347 file silcapi.h that deprecates the ops.h file and defines the
1348 published Client Library API. Defined also private message key
1349 API and channel private key API into the file.
1351 This is the file that the application must include from the
1352 SILC Client Library. Other files need not be included by
1353 the application anymore.
1355 * Added new key_agreement client operation callback and also
1356 defined the Key Agreement library API for the application.
1358 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1361 is used by clients to request key negotiation between another
1362 client in the SILC network. If the negotiation is started it
1363 is performed using the SKE protocol. The result of the
1364 negotiation, the secret key material, can be used for example
1365 as private message key.
1367 Implemented the Key Agreement payload into the files
1368 lib/silccore/silauth.[ch].
1370 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Redefined ciphers for the SILC protocol. Added some new ciphers
1373 and defined the key lengths for the algorithms. Changed the
1374 code accordingly. The default key length is now 256 bits.
1376 * Fixed SKE key distribution function silc_ske_process_key_material
1377 when the key length is more than 128 bits. The default key
1378 length in SILC is now 256 bits.
1380 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1381 to indicate unsupported algorithm.
1383 * Renamed rijndael.c to aes.c and all functions as well.
1385 * Fixed a long standing channel key setting bug in client library.
1386 Weird that it has never surfaced before.
1388 * Fixed bug in channel deletion. If the entire channel is removed
1389 then it must also delete the references of the channel entry
1390 from the client's channel list as the client's channel entry and
1391 the channel's client entry share same memory.
1393 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Implemented CONNECT and SHUTDOWN commands in the client.
1397 * Implemented CLOSE command to the client.
1399 * Added the function silc_idlist_find_server_by_name into the
1400 files silcd/idlist.[ch].
1402 Added the function silc_idlist_find_server_by_conn into the
1403 files silcd/idlist.[ch].
1405 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * DIE command was renamed to SHUTDOWN. Updated the both code
1410 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1411 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1413 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1416 * Added function silc_server_create_connection function to create
1417 connection to remote router. My server implementation actually
1418 does not allow router to connect to normal server (it expects
1419 that normal server always initiates the connection to the router)
1420 so the CONNECT command is only good for connecting to another
1423 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1426 or some other client was kicked from the channel.
1428 Implemented the handling of the notify type to both client
1431 Implemented silc_server_send_notify_kicked to send the KICKED
1432 notify. It is used to send it to the server's primary router.
1434 * Implemented the KICK command into server and client.
1436 * Added `query' argument to the silc_idlist_get_client function
1437 to indicate whether to query the client from server or not if
1440 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1441 to indicate that the client is not channel founder.
1445 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Removed the rng context from SilcPacketContext structure and
1448 changed that the packet routine uses the Global RNG API.
1450 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1452 * Added support for quit message that client can "leave" on the
1453 channel when it quits the SILC. It is ditributed inside the
1454 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1456 Added silc_server_free_client_data that will take the
1457 signoff message as argument.
1459 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1461 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Updated parts of the protocol specification to keep it up
1466 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1469 payloads in one packet.
1471 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1472 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1473 use now the new List flag.
1475 * Also deprecated the following packet types: REPLACE_ID,
1476 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1478 * Added list support for Notify packet in server.
1480 * Added silc_server_send_notify_channel_change to send the
1481 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1482 the silc_server_send_replace_id.
1484 * Added silc_server_send_notify_nick_change to send the
1485 NICK_CHANGE notify type. Deprecates the function
1486 silc_server_send_replace_id.
1488 * Added silc_server_send_notify_join to send the JOIN notify type.
1489 Deprecates the function silc_server_send_new_channel_user.
1491 * Added silc_server_send_notify_leave to send LEAVE notify type.
1492 Deprecates the function silc_server_send_remove_channel_user.
1494 * Added silc_server_send_notify_cmode and
1495 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1496 types. Deprecates the silc_server_send_set_mode function.
1498 * Added SERVER_SIGNOFF notify type to indicate that server has
1499 quit. This means that all clients on the channel from that
1500 server will drop. This can be also used when netsplit happens.
1502 Deprecated REMOVE_ID packet type since it is not needed anymore
1505 Added silc_server_send_notify_server_signoff to send the
1506 SERVER_SIGNOFF notify type. Deprecates the function
1507 silc_server_send_remove_id.
1509 Added also silc_server_send_notify_signoff to send the
1510 SIGNOFF notify type.
1512 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1513 SILC protocol from this day on. Changed the protocol
1514 specification as well.
1516 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1517 notify type. It is used between routers to notify about
1518 topic changes on a channel.
1520 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1523 * Partly updated the protocol specification to comply with the
1524 changes now made. It is still though a bit outdated.
1526 * The JOIN notify type now takes one extra argument <Channel ID>.
1527 The packet used to be destined to the channel but now the
1528 JOIN type may be sent as list thus it is impossible to
1529 destine it to any specific channel. By adding this argument
1530 it is again possible.
1532 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1534 * Added CREDITS file. The CHANGES and CREDITS file will appear
1535 in the distribution as well.
1537 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1539 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1540 types in the server's silcd/packet_receive.c.
1542 * Implemented CMODE and CUMODE to work in router environment.
1544 * Fixed minor encoding and decoding buglet from the
1545 lib/silccore/silcmode.c.
1547 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1550 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1552 * Changed all SilcConfigServer* and silc_config_server* to
1553 SilcServerConfig* and silc_server_config*, respectively.
1556 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Associated the ID (client or server ID) to the Authentication
1559 Payload to avoid any possibility of forging. Updated the
1560 protocol specification and the code accordingly.
1562 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * The RSA key length is now save to the RsaKey context in the
1565 key generation process in lib/silccrypt/rsa.c. The key length
1566 is now used to figure out the maximum size of the block allowed
1567 to be encrypted/signed.
1569 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1570 is equivalent to the silc_mp_mp2bin but does not allocate any
1573 * Changed silc_mp_mp2bin API to take length argument. If it is
1574 non-zero then the buffer is allocated that large. If zero, then
1575 the size is approximated using silc_mp_sizeinbase, which however
1578 * Created Global RNG API which is global RNG that application can
1579 initialize. After initializing, any routine anywhere in the
1580 code (including library) can use RNG without allocating a new
1581 RNG object. This was done to allow this sort of use of the
1582 RNG in code that has no chance to allocate RNG object. All
1583 applications currently allocate this and many routines in the
1584 library use this. Affected file lib/silccrypt/silcrng.[ch].
1586 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1587 it to use the Global RNG API.
1589 * Defined Authentication Payload into protocol specification that
1590 is used during SILC session to authenticate entities. It is
1591 used for example by client to authenticate itself to the server
1592 to obtain server operator privileges.
1594 Implemented this payload into the lib/silccore/silcauth.[ch].
1595 Implemented also routines for public key based authentication
1596 as the new protocol specification dictates.
1598 Moved definitions of different authentication methods from
1599 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1601 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1602 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1603 silc_pkcs_verify_with_hash functions into the file
1604 lib/silccrypt/silcpkcs.[ch].
1606 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * The client entry's userinfo pointer must be always valid.
1609 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1610 will fail since it requires the userinfo. Now, the userinfo
1611 is allocated as "" if actual userinfo does not exist. Actually,
1612 it must exist and it is totally Ok to drop client connections
1613 that does not announce the userinfo. However, we will make
1614 this workaround for now.
1616 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1617 to return the remote port by socket.
1619 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1621 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1622 SILC_SERVER_PENDING_EXEC and added an new macro
1623 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1624 data or when error occurs while processing the pending command.
1626 Added new argument `destructor' into silc_server_command_pending
1627 and to the SilcServerCommandPending object. This destructor is
1628 now called after calling the pending callback or if error occurs
1629 immediately. If error occurs the actual pending callback won't
1630 be called at all - only the destructor. The destructor may be
1631 NULL if destructor is not needed.
1633 All this applies for client library code as well. Similar
1634 changes were made there as well for the pending commands.
1636 In the client, the application must now allocate the
1637 SilcClientCommandContext with the silc_client_command_alloc
1640 * Added reference counter to the SilcServerCommandContext. Added
1641 function silc_server_command_alloc and silc_server_command_dup
1644 Same type of functions added to the client library for the same
1647 * Removed the cmd_ident from IDListData away since it is now
1648 global for all connections. It is the command identifier used
1649 in command sending and with pending commands. The affected file
1652 * Added reference counter to the SilcSocketConnection objecet to
1653 indicate the usage count of the object. The object won't be
1654 freed untill the reference counter hits zero. Currently only
1655 server uses this, and client ignores it. The client must be
1656 set to use this too later. The affected files are
1657 lib/silccore/silcsockconn.[ch]. Added also the function
1658 silc_socket_dup to increase the reference counter.
1660 This was mainly added because it is possible that the socket
1661 is removed underneath of pending command or other async
1662 operation. Now it won't be free'd and proper DISCONNECTING
1663 flags, etc. can be set to avoid sending data to connection that
1664 is not valid anymore.
1666 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1667 the connection. After that it sets SILC_SET_DISCONNECTED.
1668 It is, however, possible that the socket data is not still freed.
1669 The silc_server_packet_process now checks that data is not
1670 read or written to connection that is DISCONNECTED. The socket
1671 get's freed when the reference counter hits zero.
1673 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Changed the client operation API: channel_message operation's
1676 `sender' is now the client entry of the sender, not the nickname
1677 and the `channel' is the channel entry, not the channel name.
1679 In the private_message operation the `sender' is now also the
1680 client entry of the sender not the nickname.
1682 Affected file is lib/silcclient/ops.h and all applications
1683 using the client operations.
1685 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Moved the calling of ops->connect() from connect_to_server_final
1688 into receive_new_id functin since that is the point when the
1689 client is actually allowed to send traffic to network. The
1690 affected file is lib/silcclient/client.c.
1692 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1695 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1696 (if needs broadcasting) instead of broadcasting the packets one
1697 by one which would make a burst in the network traffic.
1699 * Added `broadcast' argument to the functions in silcd/server.[ch]
1700 silc_server_create_new_channel[_with_id] to indicate whether
1701 to send New Channel packet to primary router.
1703 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Added new function into the silcd/server.[ch] files:
1706 silc_server_create_new_channel_with_id to create new channel with
1707 already existing Channel ID.
1709 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1710 lib/silccore/silcpacket.h. This packet is used t send list of
1711 Set Mode payloads inside one packet. Server uses this to set
1712 the modes for the channels and clients on those channels, that it
1713 announced to the router when it connected to it. The protocol
1714 specification has been updated accordingly.
1716 * The silc_server_new_channel did not handle the packet coming
1717 from normal server as it normally does not send that. However,
1718 when it announces its channels it does send it. Implemented
1719 the support for that.
1721 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1722 into the file lib/silccore/id.h.
1724 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Fixed memory leaks in the functions silc_idlist_del_client,
1727 silc_idlist_del_channel and silc_idlist_del_server in the file
1728 silcd/idlist.c. All of those leaked like a sieve.
1730 * Fixed some small memory leaks in the client's function
1731 silc_client_notify_by_server.
1733 * Added functions into silcd/server.c: silc_server_announce_clients,
1734 silc_server_announce_channels and silc_server_announce_server.
1735 These functions are used by normal and router server to announce
1736 to its primary router about clients, channels and servers (when
1737 router) that we own. This is done after we've connected to the
1740 These functions effectively implements the following packet types:
1741 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1742 and SILC_PACKET_NEW_ID_LIST.
1744 * Added new functions into the silcd/packet_receive.[ch]:
1745 silc_server_new_id_list, silc_server_new_channel_list and
1746 silc_server_new_channel_user_list to handle the incoming
1747 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1749 * Added support of changing Channel ID in the function
1750 silc_server_replace_id. If the server that announces a channel
1751 to the router already exists in the router (with same name but
1752 with different Channel ID), router is responsible to send
1753 Replace ID packet to the server and force the server to change
1754 the Channel ID to the one router has.
1756 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1757 client that the Channel ID has been changed by the router. The
1758 normal server sends this to the client. Client must start using
1759 the new Channel ID as the channel's ID.
1761 Implemented handling of this new type into lib/silcclient/client.c
1762 into the function silc_client_notify_by_server.
1764 * Added new function silc_idlist_replace_channel_id into the files
1765 silcd/idlist.[ch] to replace the Channel ID.
1767 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Call silc_server_command_identify_check always when processing
1770 the IDENTIFY command in silcd/command.c
1772 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1775 send keepalive packets. The packet can be sent by clients,
1776 servers and routers.
1778 Added function silc_socket_set_heartbeat into the file
1779 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1780 If not set, the heartbeat is not performed. The actual
1781 heartbeat is implemented in the low level socket connection
1782 library. However, application is responsible of actually
1785 Added silc_server_send_heartbeat to send the actual heartbeat
1786 packet into silcd/packet_send.[ch]. Server now performs
1787 keepalive with all connections.
1789 * Added silc_task_get_first function into lib/silcutil/silctask.c
1790 to return the timeout task with shortest timeout. There was a bug
1791 in task unregistration that caused problems. TODO has been
1792 updated to include that task system must be rewritten.
1794 * The client library will now resolve the client information when
1795 receiving JOIN notify from server for client that we know but
1796 have incomplete information.
1798 * Rewrote parts of silc_server_remove_from_channels and
1799 silc_server_remove_from_one_channel as they did not remove the
1800 channel in some circumstances even though they should've.
1802 * Encryption problem encountered in server:
1804 The LEAVE command used to send the Channel Key packet to the
1805 router immediately after generating it. However, the code
1806 had earlier sent Remove Channel user packet but not immediately,
1807 ie. it was put to queue. The order of packets in the router
1808 was that Channel Key packet was first and Remove Channel User
1809 packet was second, even though they were encrypted in the
1810 reverse order. For this reason, MAC check failed. Now, this
1811 is fixed by not sending the Channel Key packet immediately but
1812 putting it to queue. However, this is more fundamental problem:
1813 packets that are in queue should actually not be encrypted
1814 because packets that are sent immediately gets encrypted
1815 actually with wrong IV (and thus MAC check fails). So, packets
1816 that are in queue should be encrypted when they are sent to
1817 the wire and not when they put to the queue.
1819 However, the problem is that the current system has not been
1820 designed to work that way. Instead, the packet is encrypted
1821 as soon as possible and left to the queue. The queue is then
1822 just purged into wire. There won't be any fixes for this
1823 any time soon. So, the current semantic for packet sending
1826 o If you send packet to remote host and do not force the send
1827 (the packet will be in queue) then all subsequent packets to the
1828 same remote host must also be put to the queue. Only after the
1829 queue has been purged is it safe again to force the packet
1832 o If you send all packets immediately then it safe to send
1833 any of subsequent packets through the queue, however, after
1834 the first packet is put to queue then any subsequent packets
1835 must also be put to the queue.
1837 Follow these rules and everything works fine.
1839 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added new function silc_server_remove_clients_by_server to
1842 remove all client entries from ID list when the server connection
1843 is lost. In this case it is also important to invalidate all
1844 client entires as they hold the invalid server entry. This
1845 fixes fatal bug when server has lost connection and will reconnect
1848 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Made some sanity checks to silc_server_daemonise like to check
1851 whether the requested user and group actually exists.
1853 * Added sanity check to SKE's silc_ske_responder_finish to check
1854 that the public and private key actually is valid.
1856 * Invalidate the client's nickname when receiving Replace ID
1857 packet and the Client ID is being replaced. This means that the
1858 server will query the nickname if someone needs it (client)
1861 * Sort the ID Cache in client library when the ID Cache data
1862 has changed (needs sorting).
1864 * Do not allow for SILC client to create several connections to
1865 several servers. The client does not support windows right now
1866 and generating multiple connections causes weird behaviour.
1868 Irssi-silc client does support windows and can handle several
1869 connections without problems, see: www.irssi.org and SILC plugin.
1871 * Fixed some places where client was added to the IDList. The
1872 rule of thumb is following (in order to get everything right):
1873 If the client is directly connected local client then the
1874 `connection' argument must be set and `router' argument must be
1875 NULL to silc_idlist_add_client function. If the client is not
1876 directly connected client then the `router' argument must
1877 bet set and the `connection' argument must be NULL to the
1878 silc_idlist_add_client function.
1880 * The funtion silc_server_packet_send_local_channel actually did
1881 not check whether the client was locally connected or not. It
1882 does that now. Fixed a bug related to LEAVE command.
1884 * Fixed Remove Channel User payload parsing bug in server's
1885 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1887 * The server's silc_server_save_channel_key now checks also the
1888 global ID list for the channel as it might not be in the local
1889 list. Fixed a bug related to LEAVE command.
1891 * Is this the end of the [<unknown>] buglet that has been lurking
1892 around for a long time? A little for loop fix in server's
1893 silc_server_command_whois_parse that is used by both IDENTIFY
1894 and WHOIS command. At least, this was a clear bug and a cause
1895 of one type of [<unknown>] buglet.
1897 * WHOIS and IDENTIFY commands call the function
1898 silc_server_command_[whois/identify]_check function even if
1899 we are not router server.
1901 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Added --with-gmp configuration option. If set the GMP
1904 is always compiled in the SILC source tree. If not set then
1905 it is checked whether the system has the GMP3 installed. If
1906 it has then the GMP won't be compiled (the system's headers
1907 and library is used), if it doesn't have it then the GMP is
1908 compiled in the SILC source tree.
1910 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Changed RSA private exponent generation to what PKCS #1
1913 suggests. We try to find the smallest possible d by doing
1914 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1915 not security fix but optimization.
1917 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Added new config entry [Identity] to fork the server and run
1920 it as specific user and group. A patch from Bostik.
1922 * Imported Dotconf configuration library into lib/dotconf.
1923 This will be used to create the SILC configuration files later.
1924 It will appear in the distsribution after this commit.
1926 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1928 * A big code auditing weekend happening. Auditing code for
1929 obvious mistakes, bugs and errors. Also, removing any code
1932 Removed files for being obsolete:
1934 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1935 inline in the file lib/silcutil/silcbuffer.h)
1937 o lib/silcutil/silcbufutil.c (the header has inline versions)
1939 Changed code to fix possible error conditions:
1941 o The buffer formatting routines now check that the destination
1942 buffer really has enough space to add the data. This applies for
1943 both buffer formatting and unformatting
1944 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1945 unformatting was changed to accomodate following rules:
1946 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1947 sent to the function while XXX_*STRING will not allocate or copy
1948 the data into the buffer. Instead it sets the pointer from the
1949 buffer into the pointer sent as argument (XXX_*STRING used to
1950 require that the pointer must be allocated already). This change
1951 makes this whole thing a bit more consistent and more optimized
1952 (note that the data returned in the unformatting with XXX_*STRING
1953 must not be freed now). The routines return now -1 on error.
1955 o Tried to find all code that use buffer_format and buffer_unformat
1956 and added return value checking to prevent formatting and
1957 especially unformatting errors and possible subsequent fatal
1960 o Changed ske->x and ske->KEY to mallocated pointers in
1961 lib/silcske/silcske.h. Fixed possible data and memory leak.
1963 o Added return value checking to all *_parse* functions. Fixed
1964 many memory leaks as well.
1966 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1967 so that buffer overflows would not happen. All code now also
1968 checks the return value as it can fail.
1970 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Added reconnection support to server if the normal server looses
1973 its connection to the router (for example if router is rebooted).
1974 The server performs normal reconnection strategy implemented
1975 to the server. Affected file silcd/server.c.
1977 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Added new packet type SILC_PACKET_SET_MODE that is used to
1980 distribute the information about changed modes (for clients,
1981 channels and clients channel modes) to all routers in the
1982 network. Updated the protocol specification accordingly.
1984 Added functions into silcd/packet_send.c and
1985 silcd/packet_receive.c: silc_server_send_set_mode,
1986 silc_server_set_mode.
1988 Added new files silcmode.[ch] into lib/silccore that implements
1989 the encoding and decoding of Set Mode Payload. Added new type
1990 SilcSetModePayload. Moved the definitions of different modes
1991 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1993 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Oops, a little mistake in server's connection authentication
1996 protocol. The protocol is not ended with FAILURE but with
1997 SUCCESS if the authentication is Ok. :) Affected file is
2000 * Implemented NICK_CHANGE notify handling in server in the file
2001 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2002 the local clients on the channel. After the changing nickname
2003 in router environment snhould work and the [<unknown>] nickname
2004 should appear no more.
2006 The silc_server_replace_id function that receives the Replace ID
2007 payload now sends the NICK_CHANGE notify type also in the file
2008 silcd/packet_receive.c
2010 * Changed WHOIS and IDENTIFY command to support the maximum amount
2011 of arguments defined in protocol specs (3328 arguments). This
2012 fixed a bug that caused problems when there were more than three
2015 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Added extra parameter, command identifier, to the
2018 silc_client_send_command so that explicit command identifier
2021 Changed that ID list routines uses specific command identifier
2022 when sending WHOIS/IDENTIFY requests to the server so that they
2023 can be identified when the reply comes back.
2025 Affected files lib/silcclient/command.[ch],
2026 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2028 * Added `sender' argument to silc_server_packet_send_to_channel
2029 to indicaet the sender who originally sent the packet to us
2030 that we are now re-sending. Ignored if NULL. Affected file
2031 silcd/packet_send.[ch].
2033 * Added some server statistics support in silcd/server_internal.h
2034 SilcServerStatistics structure and around the server code. Also
2035 send some nice statistics information when client is connecting
2038 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Fixed channel ID decoding in server's JOIN command reply in
2041 silcd/command_reply.c
2043 * Fixed braodcasting of replace ID payload to not to send it if
2044 we are standalone server in silcd/packet_receive.c.
2046 * Fixed all channel message sending routines to not to send
2047 packets to clients that has router set, since they are routed
2048 separately in the same function earlier. Affects file
2049 silcd/packet_send.c and all channel packet sending functions.
2051 * In USERS reply, res_argv[i] are not allocated, the table
2052 is allocated. Thus changed that free the table, not its
2055 * In server's whois_check and identify_check if the client is
2056 locally connected do not send any WHOIS commands - they are not
2059 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Fixed some minor bugs in client when sending WHOIS command. The
2062 arguments was in wrong order.
2064 * Removed statis function add_to_channel from server in
2065 silcd/command.c that was previously used with the joining but
2068 * Tested USERS command in router environment successfully with two
2069 routers, two servers and two clients.
2071 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Reorganized the USERS command and command reply in client library
2074 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2075 When the command is given by user we register a pending command
2076 callback that will reprocess the command after the reply has been
2077 received from the server. When reprocessing the packet we then
2078 display the information. Thus, the USERS information is displayed
2079 now in the command callback instead of in the command reply
2080 callback. The processing of the command is same as previously
2081 when server has sent the command reply in the JOINing process.
2083 * Added to USERS command in silcd/command_reply.c to join the client,
2084 we didn't use to know about, to the channel after we've created
2085 a client entry for it. Also, for clienet we did know already still
2086 check whether it is on the channel or not and add it if not.
2088 * Removed silc_server_command_join_notify as the function and its
2091 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Changed the client's pending command handling to the same as the
2094 server's pending command handling. It is also now possible to
2095 execute command reply functions from other command reply
2096 function as the function callbacks for commands and command
2097 replies are one and same. The pending commands are not static
2098 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2099 in client connection context. Thus, pending commands are server
2100 connection specific as it is convenient.
2102 Changed the function silc_client_command_pending and
2103 silc_client_command_pending_del and added new function
2104 silc_client_command_pending_check. Removed the
2105 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2108 * Added cmd_ident, current command identifier, to the client
2109 connection context in lib/silcclient/client.h to keep track on
2110 command identifiers used in command sending. Client's command reply
2111 function handling now supports the mandatory command identifiers.
2113 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2114 funtions in client to fully support pending command callbacks.
2116 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2117 as one of the arguments to the application in the command reply
2120 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2121 before first releasing SILC but came back. Now it is removed again
2122 and should come back nomore. The FORWARDED flag was used only
2123 by the JOINing procedure by forwarding the command packet to router.
2124 Now, the JOINing procedure has been changed to more generic (due
2125 to various router environment issues) and FORWARDED is not needed
2126 anymore for anything. The protocol specification is yet to be
2129 Now, removed silc_server_packet_forward from server and the flag
2130 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2132 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Renamed NAMES command to USERS command. The NAMES was named that
2135 due to historical reasons. Now it is renamed. Also, rewrote
2136 parts of the USERS command. The nickname list is not sent anymore
2137 by the server. Only Client ID and mode lists are sent in the USERS
2138 command. Changed this also to the protocol specification.
2140 The client now resolves the names and stuff after it receives
2141 the USERS list from the server when joining to the channel.
2143 * WHOIS and IDENTIFY commands has been changed to support multiple
2144 Client ID's per command. One can now search for multiple users
2145 in the network by sending only one WHOIS or IDENTIFY command.
2146 Changed the code and the protocol specifications.
2148 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2149 uses silc_server_command_whois_parse to parse the request. */
2151 * If normal server, do not parse the WHOIS and IDENTIFY requests
2152 before sending it to the router. Saves some time.
2154 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Fixed JOIN command on client library. Wrong number of arguments
2157 used to crash the client.
2159 * Added silc_server_channel_has_global function to check whether
2160 channel has global users or not.
2162 * Added silc_server_channel_has_local function to check whether channel
2163 has locally connected clients on the channel.
2165 * The silc_server_remove_from_one_channel now checks whether the
2166 channel has global users or not after given client was removed from
2167 the channel. It also checks whether the channel has local clients
2168 on the channel anymore. If it does not have then the channel entry
2169 is removed as it is not needed anymore.
2171 * The silc_server_notify now checks on JOIN notify whether the joining
2172 client is one of locally connected or global. If it is global then
2173 the channel has now global users on the channel and that is marked
2174 to the channel entry. Also, it now saves the global client to
2175 global list who is joining and JOINs it to the channel. This is
2176 for normal server, that is.
2178 Changed silc_server_send_notify_on_channel,
2179 silc_server_packet_relay_to_channel and
2180 silc_server_packet_send_to_channel check if we are normal server
2181 and client has router set (ie. global client) do not send the
2182 message to that client, as it is already routed to our router.
2184 * Implemented LEAVE notify type handling in silc_server_notify
2187 * Tested LEAVE command in router environment successfully. Tested
2188 with two routers, two servers and two clients.
2192 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2194 * Implemented SIGNOFF notify type handling in silc_server_notify
2197 * silc_server_remove_id now removes the client entry from all channels
2198 it has joined and thusly sends SIGNOFF notify type.
2200 * Rewrote the NAMES list generation in server by removing two excess
2201 loops. The lists are created now inside one loop.
2203 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * silc_server_remove_channel_user checks now also global list
2206 for channel and client.
2208 * silc_server_new_channel_user checks now both local and global
2209 list for channel and client. Fixed a bug in client id decoding.
2210 Used to decode wrong buffer.
2212 * silc_server_channel_message checks now both local and global
2213 list for channel entry.
2215 * Tested channel joining (hence JOIN) in router environment
2216 successfully. Tested with two routers, two servers and two
2219 * Tested channel message sending in router environment successfully.
2221 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Added silc_server_save_channel_key into server.[ch] to save the
2224 received channel key in Channel Key payload processing. It is
2225 also used in JOIN command reply handling.
2227 Equivalent function silc_client_save_channel_key added into
2228 client.[ch] into client library.
2230 * Changed JOIN command reply to send information whether the channel
2231 was created or not (is existing already) and the channel key
2232 payload. Changed protocol specs accordingly.
2234 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2235 the request was sent by ID and not by nickname. Crashed on
2238 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2241 now correctly save the received data.
2243 * silc_server_free_sock_user_data now notifies routers in the
2244 network about entities leaving the network.
2246 At the same time implemented functions silc_server_remove_id
2247 and silc_server_send_remove_id to receive and send REMOVE_ID
2248 packets. The packet is used to notify routers in the network
2249 about leaving entities. The ID removed will become invalid in
2252 * Added function silc_idlist_del_server into server. Removes and
2253 free's server entry from ID list.
2255 * silc_server_private_message function now checks, if we are router,
2256 that the destination ID really is valid ID, naturally.
2258 * In router when NEW_ID packet is received (for new client) the
2259 hash of the Client ID is saved in the ID Cache but the
2260 client->nickname is set to NULL, instead of putting the hash
2263 IDENTIFY command now also checks that client->nickname must be
2264 valid. If it is not if will request the data from the server who
2265 owns the client. Added new function
2266 silc_server_command_identify_check.
2268 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2269 to set the command to already allocated Command Payload.
2271 * Tested private message sending in router environment with two
2272 routers, two servers and two clients. Fixed minor bugs and now
2275 * Fixed segfault from client's NAMES command. Used to crash if
2278 * Forwarded packets must not be routed even if it is not destined
2279 to the receiver. Changed server code comply with this.
2281 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added `require_reverse_mapping' boolean value to ServerParams
2284 structure. If TRUE (not default) the server will require that
2285 the connecting host has fully qualified domain name.
2287 If the reverse mapping is not required and hostname could not be
2288 found the IP address is used as hostname.
2290 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Implemented version string checking to both client and server.
2293 The check is incomplete currently due to the abnormal version
2294 strings used in development version of SILC.
2296 * Changed all command functions in server to use the new
2299 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Changed char *data to unsigned char *data in ID Cache system to
2302 support binary data as ID Cache data. Changed code to support
2303 binary data in lib/silccore/idcache.c.
2305 * Renamed silc_server_packet_relay_command_reply to
2306 silc_server_command_reply as it is normal packet receiving
2307 function. Rewrote the function to accept command replys for
2308 servers and not only for clients.
2310 * Mark remote router always as registered server if we are connecting
2311 to it. Otherwise, commands sent by the router to us are ignored.
2313 * All ID List find routines now returns the ID Cache Entry pointer
2314 as well if requested.
2316 * WHOIS command works now in router environment, tested with two
2317 routers, two servers and two clients.
2319 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2320 in router environment (as it is almost equivalent to WHOIS) but
2321 hasn't been tested thoroughly. Added new functions:
2323 silc_server_command_identify_parse
2324 silc_server_command_identify_send_reply
2325 silc_server_command_identify_from_client
2326 silc_server_command_identify_from_server
2328 * Disabled route cache adding because adding two different ID's with
2329 same IP replaces the old cache entry thus giving wrong route.
2330 The entry->router->connection is always the fastest route anyway
2331 so route cache may not be needed. Of course, new routes maybe
2332 established after receiving the ID when the entry->router->connection
2333 might not be anymore the most optimal.
2335 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Add route cache for received ID for fast routing.
2339 * Added silc_server_packet_route to route received packet on router
2340 that is not destined to us.
2342 * Renamed silc_server_get_route to silc_server_route_get.
2344 * Added id_string and id_string_len fields into SilcServer to
2345 include encoded ServerID for fast comparing without excess
2346 encoding of the ID's.
2348 * Cleaned up WHOIS command on server side. Added following static
2351 silc_server_command_whois_parse
2352 silc_server_command_whois_check
2353 silc_server_command_whois_send_reply
2354 silc_server_command_whois_from_client
2355 silc_server_command_whois_from_server
2357 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2358 arguments in command replies. All command functions should be
2359 updated to use this macro.
2361 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Minor typo fixes on command reply handling on server.
2365 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Added silc_server_command_add_to_channel internal routine to add
2368 the client to the channel after router has created the channel and
2369 sent command reply to the server.
2371 * Added generic silc_server_send_command to send any command from
2374 * Use static buffer with ID rendering instead of duplicating data.
2376 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Fixed a channel user mode bug when joining to a channel server gave
2379 everybody channel founder rights, oops.
2381 * We mark ourselves as the router of the incoming server connection
2382 if we are router ourselves. This way we can check in some packet
2383 sending functions whether it is locally connected server. For
2384 incoming router connections we put NULL.
2386 * For router sending packets locally means now always sending the
2387 packet cell wide; to local clients and local servers. For normal
2388 server sending packet locally means sending it to only local
2391 * Fixed the JOIN command to really work in router environment. If the
2392 channel is created it is always created by the router. Router is
2393 also responsible of making the initial joining to the channel,
2394 sending JOIN notify to the sending server and distributing
2395 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2396 does not exist server doesn't do anything else but forward the
2397 command to the router which performs everything.
2399 * Added silc_server_send_channel_key function to send the Channel Key
2402 * Added silc_server_create_channel_key to create new channel key. The
2403 channel key is now re-generated everytime someone joins or leaves
2404 a channel, as protocol dictates. Note: channel->key_len is the
2407 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2410 packet_receive.[ch] to separate packet sending and receiving
2411 routines. The server.[ch] now includes everything else including
2412 actual packet processing (writing and reading data) and other
2415 Renamed silc_server_private_message_send_internal to
2416 silc_server_send_private_message. The routine is still though
2417 used only to relay private messages as server does not send
2418 private messages itself.
2420 Renamed silc_server_new_channel to silc_server_create_new_channel
2421 and added new function sicl_server_new_channel that handles the
2422 incoming New Channel packet. Added also new sending function
2423 silc_server_send_new_channel to send New Channel Payload.
2425 * Added new function silc_server_notify to process incoming notify
2426 packet to the server/router. Server may then relay the notify
2427 to clients if needed.
2429 * Added new function silc_server_new_channel_user to process incoming
2430 New Channel User packet. Router will redistribute the packet and
2431 send JOIN notify to its local clients and locally connected servers
2432 if needed. Normal server will send JOIN notify to its local client
2433 on same channel when received this packet. Added also corresponding
2434 sending function silc_server_send_new_channel_user to sent the
2437 * Added boolean route argument to send_notif_to_channel and
2438 packet_send_to_channel functions to attempt to route the packet
2439 if it is TRUE and send only locally if it is FALSE.
2441 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * silc_server_replace_id now broadcasts the received replace ID
2444 packet if it is not broadcast packet already. The router must
2445 broadcast to inform other routers about changed ID.
2447 * Added backpointer to server's router into SilcServer context in
2448 silcd/server_internal.h.
2450 * Fixed silc_server_packet_broadcast to send correct broadcast
2453 * The channel key is now distributed to the local client as soon
2454 as it is received from the router (in router environment) so that
2455 no other packet may be sent for the channel until client has
2458 * silc_server_remove_channel_user now broadcasts the received
2459 Remove Channel User packet if it is not broadcast packet already.
2460 The router must broadcast to inform other routers about removed
2463 * Added users field into SilcPacketContext that is a reference count
2464 of the context. One can increase the reference count by calling
2465 silc_packet_context_dup which is now changed to just increase the
2466 reference count instead of duplicating the data. The reference
2467 count is decresed by calling silc_packet_context_free that will
2468 free the data after the reference count hits zero.
2470 For now on the packet context and everything allocated into it
2471 (including the raw packet from network) must be freed by calling
2472 the new silc_packet_context_free function. Added also new function
2473 silc_packet_context_alloc that must be used now to allocate the
2474 context. This also means that if a routine is asynchronous from
2475 silc_[client/server]_packet_parse_type the packet context must
2476 be duplicated by calling silc_packet_context_dup. Otherwise it
2477 gets free'd after silc_[client/server]_packet_parse_type returns.
2478 Also, one must remember that if packet is duplicated then its
2479 reference count must be decresed by calling the free function as
2480 many times as it was duplicated.
2482 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2483 from both client and server.
2485 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Made joining to a channel working in router environment.
2489 * Cleaned up JOIN command on server side and create function
2490 silc_server_command_join_channel internal routine to make the
2493 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Changed silc_command_pending list to SilcDList. Also, added
2496 `ident' field to SilcServerCommandPending structure to identify
2497 the reply and to call correct callback.
2499 Added silc_server_command_pending_check function to replace the
2500 corresnponding macro. The silc_command_pending list is not
2503 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2504 to set identifier to previously allocated Command Payload. It
2505 is used to set identifier for command when resending Command
2508 * Added silc_command_payload_encode_payload to encode Command
2509 Payload buffer from SilcCommandPayload structure.
2511 * Added silc_argument_payload_encode_payload to encode Argument
2512 payload buffer from SilcArgumentPayload structure.
2514 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Changed WHOIS command to support router connection on server side.
2517 The whois request is always sent to router unless the server is
2518 standalone server. After server has received the reply from the
2519 router will it send the reply to the client.
2521 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2522 broadcast received broadcast packet. The function is used only
2523 by router. The broadcast packet is always sent to the router's
2526 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2527 render given ID to printable string, for log files for example.
2529 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Made basic router to router connections working. At least they
2532 can now connect to each other but nothing really works the way
2533 they are supposed - yet.
2535 * Added new initiator token to RouterConnection configuration
2536 file in silcd/serverconfig.[ch]. It is used to tell whether we
2537 are the initiator to the remote router or whether we'll expect
2538 the other end to connect.
2540 * Moved registering of listener task to silc_server_init, hence
2541 the server starts listenning as soon as it is run, even if it
2542 does not have connections to other routers. Let's see how well
2545 * Changed default connection retry timeouts for more suitable in
2548 * Removed cipher and such arguments from silc_idlist_add_client
2549 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2550 Added new function silc_idlist_add_data to add the keys and stuff
2553 * Added SilcIDListData structure and added it to SilcClientEntry
2554 and SilcServerEntry as their first field in the structure. This
2555 way we can explicitly cast the ID entries to the SilcIDListData
2556 structure and get common data for the entries. In past, we had
2557 to first check what type of connection it is and then cast it to
2558 correct ID entry type. Now, we can directly cast the opaque
2559 pointer to the SilcIDListData (no matter what ID entry it actually
2560 is) and get the data needed.
2562 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2565 in some circumstances even if threre were timeout tasks, though not
2566 IO tasks, but tasks anyway. Now fixed.
2568 * Defined SilcServerConnection structure to hold connection specific
2569 stuff about directly connected servers and routers. The definition
2570 is currently in silcd/server_internal.h. I thought about having
2571 a bit more important role fro this struct but for now it is used
2572 only when connecting to other server (or router actually).
2574 * Added connecting retry support in server when connecting to
2575 router(s). The retry feature implement exponential backoff
2576 algorithm. Also, added SilcServerParams structure to hold default
2577 parameters for server. For now, it include these retry settings
2578 and are hard coded. After server is moded to be as Silc Server
2579 Library this structure will be more important.
2581 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Changed client librarys channel->clients table to SilcList and
2584 changed code accordingly.
2586 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Changed client's channel table to SilcList and changed code
2589 accordingly. Also changed SilcChannelClientEntry to include back-
2590 pointer to the channel so that client entry can use that structure
2591 as list as well and we have fast cross-reference to the channel.
2592 This change dramatically decreased the complexity of channel
2593 handling with client entry and vice versa (removed one extra
2594 loop when searching for channel entry from many functions).
2596 * Changed server->sim from table to SilcDList and changed code
2599 * NAMES command can now be used from user interface. It will show
2600 the user list on the channel, neatly.
2602 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2603 Code now saves realname of the user if it becomes available.
2605 * Renamed configure.in to configure.in.pre and made ./prepare
2606 script to automatically add correct version string to
2607 configure.in which it creates from configure.in.pre.
2609 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * NAMES command reply now shows users mode with the nickname when
2614 * Moved silc_client_ch[u]mode[_char] functions from
2615 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2616 place sucks, they are utility functions and should be in some
2619 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2621 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2624 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Added TRQ (efficient deque and list library) into lib/trq. This is
2629 a very good list library that is currently used in the SILC. Defined
2630 SilcList API over the library because I didn't like the API very
2631 much. See lib/trq/silclist.h for the API and examples of how to
2632 use the API. Fixed various places in the code to use the new
2633 SilcList API. The SilcList is meant for lists that has a structure
2634 already defined as a list. It is not suitable to add just some
2635 context to the list (in TRQ, the context is the list actually).
2637 So, I defined SilcDList that can be used for the purpose where
2638 predefined list structure does not exit. This can be used as
2639 such list. Now some context just can be added to the SilcDList.
2640 Currently this list is not used in the SILC just yet, though there
2641 are a lot places where this can replace dynamically allocated
2642 tables and I will fix these places, later, to use SilcDList.
2643 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2644 and use TRQ internally).
2646 Also fixed some annoying warning messages that the original TRQ
2647 code generated. Also minor changes to TRQ's Makefile.in.
2649 * Added support for querying by Client ID to both WHOIS and
2650 IDENTIFY commands into server, as required by the protocol.
2652 * Removed method function pointers from SilcBuffer structure. They
2653 weren't used to anything and just increased the context size for
2654 no good reason. This change also made silc_buffer_alloc and
2655 silc_buffer_free functions inline functions.
2657 * Disabled command flooding detection support until it's fixed so
2658 that it accepts commands in but does not execute them more than once
2661 * Added silc_net_localhost(), to return local hostname, into
2662 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2663 that must be initialized before calling silc_client_init.
2665 * Added new function: silc_server_send_notify_on_channels to send
2666 notify messages to all channels client has joined. It is assured
2667 that the message is sent only once per client.
2669 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2670 lib/silcutil/silcutil.[ch] as silc_format function. The new
2671 function is generic and is used by server as well, not only by
2672 the logging routines.
2674 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2675 the provided version string was not acceptable. Added new function:
2676 silc_ske_check_version into lib/silcske/silcske.h. The function
2677 must be implemented by the application (client or server) and it
2678 does not reside in the SKE library. The function checks the version
2679 string remote end sent.
2681 * Added back pointers (to opaque context and to SilcSocketConnection)
2682 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2684 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2685 duplicate packet context structure.
2687 * Changed `notify' client operation to send same arguments as client
2688 receives from server except for ID's. ID's are mapped to correct
2689 ID entry and that is returned. Also, if channel entry is not sent
2690 by server but the notify is for channel the channel entry is sent
2691 to application (otherwise application doesn't know that it is for
2692 channel (library gets it from packet's Destination ID)).
2694 * Added silc_client_remove_from_channels into client library to
2695 remove a client from all channels it has joined to. Used when
2696 received SIGNOFF notify from server. Added also new function
2697 silc_client_replace_from_channels to replace old ID entry with
2698 new ID entry on all channels. Used when received NICK_CHANGE
2701 * Fixed ID Cache list handling in silc_idlist_get_client in
2702 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2703 to get (or query) client by ID.
2705 * Updated TODO list.
2707 * Added connection authentication status message defined by the
2708 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2709 support for these into the code in client and server side.
2711 * Added generic function silc_client_send_command to send any command
2712 with variable argument list. Application should use this function
2713 to send commands if the command functions provided by the library
2714 does not suite for the application's user interface needs.
2716 * Added new `failure' client operation. Application is notified about
2717 received failure packet if client is executing a protocol. In this
2718 case the protocol's execution has failed.
2720 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2721 is required by the protocol.
2723 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2724 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2727 * Added status flag to SilcSKE object to indicate realtime status
2728 of the SKE protocol.
2730 * Application receives now exactly same command reply arguments as
2731 the library receives from server. However, if ID is received the
2732 corresponding ID entry is returned to the application (eg. Client
2733 ID is mapped to correct SilcClientEntry entry and that is returned).
2734 Changed command_reply client operation due to this change.
2736 * Changed all ID's in commands and in command replys as ID Payloads.
2737 Change affected both client and server side codes.
2739 All ID's sent in SILC network (with execption of ID's in SILC
2740 Packet header) are sent in ID Payload to support variable length
2743 * Server now notifies nick changes and notifies all clients on
2744 the channels about the new nickname (about the new Client ID,
2747 * Implemented CMODE command to change channel modes. Supports all
2748 channel modes defined by the protocol specs except ban and invite
2749 lists. (Also, private channel key mode is supported but support for
2750 setting private channel key in client is missing, thus, this mode
2751 has no effect on client side (except that server requires that the
2752 client uses private channel key and normal channel traffic does not
2755 Also, invite mode works per se, but INVITE command does not work
2756 yet correctly, so you can set channel as invite only channel but
2757 inviting clients to the channel does not work (it is yet to be
2758 thought what's the best way to do it).
2760 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2761 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2762 Implemented CUMODE command to change user's mode on the channel.
2763 Supports all modes defined by the protocol specs.
2765 * Added NAMES command reply to return users modes on the channel.
2767 * Removed unnecessary and slow ciphers from lib/silccrypt.
2769 * Set SO_KEEPALIVE option to connection sockets by default.
2771 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2773 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2774 redefined the Notify Payload into protocol specs.
2776 * Added silc_id_payload_parse_id to get ID directly from raw
2779 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2782 accept searching by Client ID as well.
2784 * Added support for LEAVE and SIGNOFF notify types in client library.
2786 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2787 to parse ID Payload from raw data.
2789 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added flags parameter into silc_ske_assemble_security_properties
2792 function in lib/silcske/silcske.[ch].
2794 * Changed notify client operation to fit better for notify messages
2795 sent by server. The notify payload received from server is now
2796 passed to the application (after parsing it to SilcNotifyPayload).
2797 It is application's responsibility to retrieve the arguments
2798 from the payload and show the message the way it wants. The message
2799 sent by server is implementation specific.
2801 * Changed public keys to comply with the protocol specification.
2802 Old public keys are not supported anymore and are not compatible.
2804 * Removed nickname from Channel Payload as the latest draft removed
2805 it. The client must resolve the nickname from the NAMES command
2806 reply received when it joined the channel.
2808 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2810 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Fixed some errors in protocol specification drafts.
2814 * Created lib/silccore/silcnotify.c to implement Notify Payload
2815 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2816 generic payloads described by protocol specifications. The file
2817 includes implementations for ID Payload and Argument Payload.
2819 * Changed Command Payload implementation to use the new Argument
2820 Payload. Changed command_xxxx_payload to command_payload_xxxx
2821 to comply with SILC coding conventions.
2823 * Added suppport for Argument Payload handling in Notify Payload
2824 implementation as protocol requires it. Added the new support
2825 into server and client lib as well.
2827 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Added support for multiple nicknames on same channel. [n] is
2830 added locally to the nickname if there are more than one same
2831 nicknames on the channel.
2833 * Server now sends all nicknames that matched WHOIS request.
2834 Client also shows the list received from server.
2836 * Added TOPIC command to client side. User can now set and show
2837 current topic on channel.
2839 * Added MOTD command to client and server. Also, server sends the
2840 motd when client connects to the server.
2842 * Changed version strings to comply ISO 8601.
2844 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Fixed protocol error handling in client library. It should now
2847 cope even if the SKE fails for some reason.
2849 * Made new protocol specification drafts for submitting to IETF.
2851 * Implemented TOPIC command to server in silcd/command.c.
2853 * Added two new notify types into lib/silccore/silcnotify.h:
2854 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2855 notify nickname change and topic setting/change on a channel.
2857 * API change of command_reply operation in client library. The
2858 application gets now the status type received from server as well.
2860 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2864 * Cras fixed and optimized the packet handling even further and
2865 it should work now. Minor change to the prototype of function
2866 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2868 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Added new function into lib/silcutil/silcschedule.[ch]:
2871 silc_schedule_with_fd to select() a specified fd. The function
2872 returns after timeout expires or data arrives or goes. The
2873 function is used by packet routines to wait that all data is
2874 received from network.
2876 * Fixed data reading from network in lib/silccore/silcpacket.c.
2877 The code now assures that all data is read from the fd and then
2878 continues packet processing. This was a bug fix since the code
2879 used to drop some data in some circumstances.
2881 * Added new function into lib/silcclient/client.[ch]:
2882 silc_client_start_key_exchange to start key exchange after
2883 connection has been established to server. The code internally
2884 now uses this funtion but its main purpose was to provide it
2885 for applications that perform their own connecting. After
2886 application has created a connection it merely calls this
2887 function to start the key exchange between client and server.
2888 The library takes care of everything else after that.
2890 Updated also lib/silcclient/README to explain the usage of
2893 * Do not send to application information that connection has
2894 been established. Application gets notified it by connect
2897 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Applied cras's patch to add silc_schedule_one function. The
2900 function runs scheduler once and returns.
2902 * Fixed the scheduler after cras messed it up. The timeout
2903 handling works now as it's supposed to work.
2905 * Added into lib/silccore/ silcnotify.h to include notify
2906 message types support. Changed silc_server_send_notify*
2907 functions, in server.[ch], to support those new notify types.
2908 Added the support for the notify types into client library,
2909 as well. Added new notify client operation into ops.h in
2912 * Changed silc_server_packet_send_to_channel to send normal
2913 packets instead of just channel message packets. The function
2914 is now used to send the notify packets to channels. It is not
2915 used to send channel message packets anymore, as server never
2918 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2919 va_arg()s as it seems to require it nowadays. I guess, if SILC
2920 is compiled with older va_arg() the new code should work anyway.
2922 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Splitted core library. Core library (lib/silccore) includes
2925 now only SILC protocol specific core (and common) components.
2926 Created new utility library (lib/silcutil) that includes more
2927 generic purpose stuff. The stuff for util library was taken
2928 from the old core library. This was minor and easy split.
2930 * Created SILC Client Library (lib/silcclient) that includes
2931 implementation of the SILC client without user interface. This
2932 was major move from silc/ directory. The code has been changed
2933 so that it is transparent towards the user interface. The
2934 silc/ directory includes now the same user interface as before
2935 and it uses the new client library. Read lib/silcclient/README.
2936 Basicly, the client library performs everything else related
2937 to SILC except user interface handling. Also, configuration
2938 files are considered to be part of user interface and library
2939 does not handle them.
2941 This change also changed a lot of structures, function naming etc.
2942 Most important change was that SilcClientWindow object was
2943 renamed to SilcClientConnection in the client library. Created
2944 also new file lib/silcclient/ops.h. Also added new files
2945 silc/local_command.[ch] and silc/client_ops.[ch].
2947 All these changes were made to make it easier for user interface
2948 designers to create what ever user interface for the SILC client
2951 It is also expected that the server will be moved to lib
2952 directory as well and SILC Server Library will be created;
2953 sometimes in the future.
2955 * Removed Local commands from lib/silccore/silccommand.h as
2956 they are application specific and new client library does not
2957 handle any of those anymore.
2959 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2960 old client implementation in silc/.
2962 * Added support for callback functions in SILC_LOG_* macros.
2963 Application can now set its own callbacks that will be called
2964 instead of using the default functions that will always print
2965 the debug messages to stderr (or stdout). Also, debugging can
2966 now be disabled by setting silc_debug to FALSE and re-enabled by
2967 setting it to TRUE. Note, that logging will still work even
2968 if debugging is disabled.
2970 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2971 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2972 silc_log_reset_debug_callbacks.
2974 * To enable debugging in silc client one must give now -d
2975 option on command line.
2977 * Changed silc_schedule_init to automatically allocate task queues
2978 if they are not allocated before calling it.
2980 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Added GMP 3.1 into math library.
2984 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2987 a channel in SILC network. The packet is used by servers and
2988 routers to notify other routers that user has left a channel.
2989 This little feature was missing until now. Added the feature
2990 to protocol specification as well.
2992 Added functions: silc_server_send_remove_channel_user and
2993 silc_server_remove_channel_user into server.[ch].
2995 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2996 lib/silccore/silcpacket.h. However, they are not implemented
2999 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed joining to a channel and sending channel messages
3002 between server and router. The channel message sending should
3003 now work inside a cell.
3005 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed the private message sending between server and router.
3008 The private message sending should now work inside a cell.
3010 * Added silc_server_replace_id into server.[ch] to replace
3011 existing ID in the SILC network.
3013 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3014 and silc_idlist_replace_server_id into idlist.[ch] in server.
3016 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed the server to server connections. Server can again now
3019 connect to router. Router to router connections probably does
3022 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Added dynamic protocol registering support. Now protocols can
3025 registered and unregistered on the fly. Patch by cras.
3027 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Added lib/contrib directory to hold routines that some platforms
3030 don't have but are needed by SILC.
3032 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3033 into lin/contrib to provide getopt() and getopt_long() for
3034 those who don't have it.
3036 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Added AWAY command to client. When away message is set and
3039 client receives a private message packet the client automatically
3040 replies to the sender with the away message.
3042 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3043 bug seemed to be the cause of recent problems when compiling
3046 * Added version detection support to SKE protocol specification
3047 and added the new changes to the SKE implementation as well.
3048 There were other minor changes in the SKE protocol as well.
3050 Many changes in lib/silcske/silcske.[ch] and in
3051 lib/silcske/payload.[ch].
3053 * Added ^U functionality, clear input line. Patch from cras.
3055 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Mainly small bugfixes on core library. Fixed some debugging
3058 logging and buffer overflow in silclog.c.
3060 * Updated config.sub and config.guess on the distribution tree.
3062 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3064 * Added command lagging support in server. Client may execute
3065 commands now only once in two seconds.
3067 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Optimized packet reception. MAC computation and checking is now
3070 also more optimized. A lot previously duplicated code is now
3071 used as generic by both client and server.
3073 * Fixed key pair generation in clientutil.c
3075 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Added into lib/silccore/silcbufutil.[ch] new function;
3078 silc_buffer_realloc.
3080 * Moved generic packet sending/encryption functions to
3081 lib/silccore/silcpacket.[ch] from client and server. Some
3082 rewriting of the functions.
3084 * Moved all generic packet reception/decryption functions to
3085 lib/silccore/silcpacket.[ch] from client and server. The
3086 packet processing is now much cleaner in both client and server.
3087 These were major changes in both client and server.
3089 * Created many common functions in server to do packet sending.
3090 Previously code were duplicated a lot, this has been removed
3093 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * Rewrote major parts of the ID cache system. Don't know
3096 whether it is better now or not but at least the API is more
3099 * Major rewrite on ID cache stuff on client because of the ID
3100 cache API changes. Added idlist.c to client.
3102 * Also major rewrite on ID cache stuff on server as well.
3103 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3104 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3105 in hand, instead they are all put into the ID cache system now.
3106 All server_idlist_* routines uses ID cache now instead of
3107 traversing its own lists (those lists does not exist anymore).
3108 SilcIDList though still exists. Also, SilcXXXEntry's are
3111 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Finally made the SKE implementation compliant to the protocol
3114 specification. All mp integers are now binary encoded as
3115 opposed being HEX encoded.
3117 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3120 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3121 functions: silc_[encode/decode]_pem. Also added function
3122 silc_encode_pem_file to PEM encode with newlines ('\n') for
3125 * SILC public keys are now encoded either PEM or binary. Same
3126 option is for private keys as well. By default private keys
3127 are binary encoded and public keys PEM encoded. Silly HEX
3128 encoding were removed.
3130 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3131 function to create fingerprints.
3133 * Fixed a bug in SHA1; does not change the original data anymore.
3135 * Partly implemented INFO command on client and server side.
3136 Fixed CLEAR command. Changes to SERVER command; show current
3137 server(s) when giving command without arguments. Added
3138 VERSION command to client.
3140 * Added check to server that unregistered connections cannot
3141 execute commands (unless it is specificly allowed).
3143 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Fixed screen refresh.
3147 * Fixed channel joining bug from client. On some circumstances
3148 client tried to join to a channel it had already joined.
3150 * Added public key verification process into client's protocol.c.
3151 The client now verifies the public key from user and saves
3152 it into ~./silc/serverkeys/ directory.
3154 Added into: clientutil.[ch]: silc_client_verify_server_key.
3156 * Changed SKE protocol's silc_ske_initiator_finish function
3157 to accept callback function that verifies the received public
3158 key. Removed old silc_ske_verify_public_key function.
3160 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3163 silc_pkcs_private_key[_data]_set.
3165 * Made the password and public authentication more cleaner in
3166 server's protocol.c.
3168 * Removed historic and obsolete protocol `channel_auth' from
3169 both client and server.
3171 * Removed wrong way of sending command status messages from
3172 server to client in server's command.c. The old way violated
3173 protocol specification.
3175 Changes to silccore/silccommand.[ch]: removed
3176 silc_command_encode_status_payload -> not needed anymore,
3177 changed silc_command_encode_payload_va to accept extra
3178 argument on variable argument list. The argument type must
3179 now be provided to the function. Also, added new function:
3180 silc_command_encode_reply_payload_va which is same as
3181 normal command_encode_payload_va except command status type
3182 is provided as extra argument.
3184 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added ~./silc directory handling. The directory includes the
3187 public and private keys for the client.
3189 Added silc_client_check_silc_dir, silc_client_create_identifier
3190 and silc_client_load_keys.
3192 * Implemented SILC protocol compliant public key. Added public
3193 and private key saving to and loading from files.
3195 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3196 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3197 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3198 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3199 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3201 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3202 silc_pkcs_load_[public/private]_key.
3204 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added silc_server_get_route (route.[ch]) to get connection
3207 data for the fastest route for given ID.
3209 * Implemented INVITE command on client and server. The command
3210 were re-defined in the SILC Protocol Specification and the
3211 implementation now complies with the specification.
3213 * Implemented PING command on client and server.
3215 * Implemented NAMES command on client and server. The server side
3216 supports currently only normal server not router server yet.
3217 Some changes to NAMES definition in SILC protocol specification.
3219 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Implemented LEAVE command on client and server.
3223 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3224 again. This change was made to the protocol as well. Server
3225 should not violate the protocol specification anymore.
3227 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3230 was tested. SOCKS4 was not but should work anyway.
