1 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the version checking in the server. Affected file is
6 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Fixed the configuration data fetching when accepting new
9 connections in the server. Affected file silcd/server.c.
11 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Added `sender_entry' argument to the function
14 silc_server_packet_relay_to_channel so that we can check
15 whether some destination actually belongs to the same route
16 the sender belongs (ie, we must not resend the packet to the
17 sender). Affected file silcd/packet_send.[ch].
19 * Added `servername' field to the SilcClientEntry in the server
20 to hold the name of the server where client is from. Affected
21 file is silcd/idlist.h.
23 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Moved the channel message encrypting in the router betwen
26 router connections from silc_server_channel_message to the
27 silc_server_packet_relay_to_channel since we want to check
28 whether we have anybody channel before encrypting anything.
29 Affected files silcd/packet_[receive/send].c.
31 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Fixed the [AdminConnection] server config section to support
34 multiple entries. Affected file silcd/serverconfig.c.
36 * Added support into the server to check the validity of the
37 incoming connection before executing any KE or authentication
40 * The connection configuration is now saved to the KE and
41 connection auth protocol contexts and not fetched anymore in
42 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
44 * The local hosts listenning address and port is also resolved
45 now when starting the server. We want to have the socket object
46 to include the real address and port for the listener. Added
47 new function silc_net_check_local_by_sock into the files
48 lib/silcutil/silcnet.[ch].
50 * Fixed a broadcast bug in server -> do not broadcast if we
53 * Fixed a routing bug. Do not route broadcast packets ever.
54 Broadcast packets must be processed always and not routed since
55 they may be destined to some other host than yourself and thus
56 would get routed without no good reason. Affected file is
59 * Added function silc_server_config_is_primary_route to check
60 whether primary router connection has been configured (a router
61 configuration that we are initiating). If there is not, we
62 will assume that there is only two routers in the SILC network
63 and we will use the incoming router connection as our primary
64 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
66 * Changed the order of the broadcasting. Broadcast _after_ the
67 packet has been processed not before. Affected file is
70 * Fixed a [ClientConnection] parsing bug. The port was never
71 parsed correctly thus resulting to port 0. Affected file
74 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
75 argument and did not set the broadcast packet flag. Affected
76 file silcd/packet_send.c. Fixed same bug in the function
77 silc_server_send_notify as well.
79 * If we receive NEW_ID packet for our own ID in the server, ignore
82 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Removed the nickname from the Private Message Payload.
87 Updated the code and the protocol specs.
89 * Updated protocol specs for submitting to the IETF.
91 * Tweaked the Random Number Generator a bit. Affected file
92 lib/silccrypt/silcrng.c. Exported a new function
93 silc_rng_[global]_add_noise which can be used to add more
96 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Do not parse packets with different timeout when protocol
99 is active -> may cause problem with rekey. Affected file
102 * When server receives signoff notify it must not create
103 new channel key if the client is on any channels since the
104 sender of the signoff notify will create it.
106 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added printing of error messages during SKE protocol from the
109 failure packet sent by server during SKE. Affected file
112 * Removed the client's failure_callback handling with timeout
113 and handle it immediately when received.
115 * The SKE library returned wrong type in SUCCESS and FAILURE
116 packets. They must be 32 bit MSB not 16 bit MSB.
118 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Ok, rewrote the logic of the re-key and now it seems to work.
121 I tested it on high traffic with frequent re-keys without
122 problems. Added hmac_receive (and renamed hmac to hmac_send)
123 in SilcClientConnection in lib/silcclient/client.h and
124 in SilcIDListData in silcd/idlist.h. Also, removed the
125 SilcPacketParserContext's cipher and hmac fields as they are
126 not needed anymore and actually caused some problems when
127 the ciphers and hmac's changed underneath the packet parser.
129 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * If re-key protocol is active then process the incoming packets
132 synchronously since we must assure that icoming packets encrypted
133 with the old key is processed before the new keys is set to
134 use. This is true other packets than for REKEY packets.
135 Affected file silcd/server.c. The same was done to client library
136 as well, affected file lib/silcclient/client.c.
138 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Fixed bug in client and server to accept the force send if
141 the packet is send from silc_[server/client]_packet_process
142 function. Otherwise the packets are never delivered, oops.
144 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Disable force sending of packets when REKEY protocol is active.
147 We must assure that no packet is sent directly when rekey is
148 performed. All packets must be sent through packet queue.
149 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
150 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
151 function is silc_[server/client]_packet_send_real to check
154 * Replaced the SIM paths from example config files to
155 /usr/local/modules. Also, make install creates now
156 /usr/local/silc/logs directory to hold all the SILC server
159 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Made the configure.in.pre work on Solaris. Patch by salo.
163 * Made all ciphers compatible with non-x86 machines. Defined
164 CBC mode macros into lib/silccrypt/ciphers_def.h.
166 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Fixed the make install.
170 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * When MAC computation fails the silc_packet_decrypt returned 0
173 even though it was supposed to return -1. Fixed this. The
174 affected file is lib/silccore/silcpacket.c.
176 * Do not replace the config files in /etc/silc (in make install)
177 if they already exist. Affected file ./Makefile.am.
179 * Do not send re-key packets immediately but through packet queue.
180 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
182 * Changed silc_net_check_host_by_sock to return FALSE if the
183 IP/DNS could not be resolved. Though, it returns the IP address
184 now even if it could not resolve it (but returns also FALSE).
185 Affected file lib/silcutil/silcnet.[ch].
187 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Added silc_pkcs_decode_identifier to decode the public key's
190 identifier. Affected file lib/silccrypt/silpkcs.[ch].
191 Added also silc_pkcs_free_identifier. Added also new context
192 SilcPublicKeyIdentifier.
194 * Added -S option to the silc client. It is used to dump the
195 contents of the specified public key file.
197 * Changed the PKCS api to return the public key length when
198 setting the public key.
200 * Fixed a fatal bug in the public and private key file loading.
201 Affected file lib/silccrypt/silcpkcs.c.
203 * Execute the packet parsing for client with zero (0) timeout
204 if the protocol is active. Affected file silcd/server.c.
206 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Made the key generation options to the silcd program. Added
209 -C option, equivalent to client's option.
211 * Added new [ServerKeys] config section to the server. It
212 configures the server's public and private key.
214 * Defined generic Public Key Payload into the protocol
215 specification to send specific type of public keys and
218 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
219 public key or certificate.
221 * Implemented the GETKEY command to the server and to the
222 client library and on user interface.
224 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Made preliminary `make install' work.
228 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Added SilcServerRekey context into silcd/idlist.h.
232 * Added the PFS support as defined in the specification to the
233 SKE protocol. Affected files lib/silcske/*.c.
235 * Added `ske_group' field to the SilcServerRekey context to hold
236 the number of the SKE group that is used with PFS in re-key.
237 Affected file silcd/idlist.h.
239 * Added PFS re-key support to the server. Affected file is
242 * Added silc_protocol_cancel to cancel execution of the next
243 state of the protocol. Affected file is
244 lib/silccore/silcprotocol.[ch].
246 * Added the re-key support with and without PFS to the client
247 library. Re-key is performed once in an hour, by default.
249 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
250 Added silc_client_rekey_callback and silc_client_rekey_final.
251 Affected files are lib/silcclient/protocol.[ch] and
252 lib/silcclient/client.[ch].
254 * Removed the `hmac_key' and `hmac_key_len' fields from the
255 SilcClientConnection structure; not needed. Affected file is
256 lib/silcclient/client.h.
260 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Do not ask whether user wants to use the negotiated private key
263 for private messages, just use it. Affected file is
264 silc/local_command.c.
266 * Added `send_enc_key' and `enc_key_len' fields to the
267 SilcIDListData structure since they are needed in the re-key
268 phase. Affected file is silcd/idlist.[ch].
270 * Implemented the simple re-key protocol into the server.
271 Affected files silcd/server.c and silcd/protocol.[ch]. The
272 re-key will be performed once in an hour, by default.
274 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
275 Added silc_server_rekey, silc_server_rekey_callback and
276 silc_server_rekey_final.
278 * Removed Tunneled flag from the protocol. Updated the code
279 and the specifications.
281 * Adde `pfs' field to the SilcIDListData to indicate whether
282 the PFS is to be performed in the re-key. Affected file is
285 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
288 int64 of at least the xintXX size. If void * is less that 4
289 bytes uint32 * will be used. Defined bool as boolean.
291 * Changed _ALL_ unsigned long and unsigned int to uint32,
292 unsgined short to uint16 in the source tree.
294 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
295 not handle clients that has entry->data.registered == FALSE.
296 They are not in the network anymore. Affected file is
299 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Implemented the sending of the SERVER_SIGNOFF notify in the
302 server. Affected file is silcd/server.c.
304 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
305 Added also silc_notify_payload_encode_args into the
306 lib/silccore/silcnotify.[ch].
308 * Implemented ther SERVER_SIGNOFF notify handling in the server.
309 Affected file silcd/packet_receive.c.
311 * Implemented the SERVER_SIGNOFF notify handling in the client
312 library. Affected file lib/silcclient/client_notify.c. Also,
313 implemnted the printing of the SERVER_SIGNOFF info to the
314 application. Affected file silc/client_ops.c.
316 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
317 if the deleting was successful. Affected file silcd/idlist.[ch].
319 * Added support for public key authentication in the connection
320 authentication protocol in the client library. Affected file
321 lib/silcclient/protocol.c.
323 * Changed the server's silc_idlist_get_clients_by_* interface
324 to support already allocated array so that new entries may be
325 added to pre-allocated array. Affected file silcd/idlist.[ch].
326 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
329 * All command reply functions in the server now calls the
330 pending command callback even if error occured. This way the
331 error will be delivered to the client as well. Affected files
332 silcd/command.c and silcd/command_reply.c.
334 * Fixed INFO command to return local server's info if no server
335 was provided. Affected file lib/silcclient/command.c.
337 * Removed RESTART command for good. Updated the code and the
340 * Rewrote parts of the task system. It is a bit simpler now.
341 Removed unsued task priorities. The affected files are
342 lib/silcutil/silctask.[ch].
344 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Moved the USERS printing from the library to the application.
347 Affected files lib/silcclient/command.c and silc/client_ops.c.
349 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Added channel key re-key support. The re-key is perfomed
354 only by the router and is done once in an hour. Added `rekey'
355 field to the SilcChannelEntry in the server. Affected files
356 silcd/server.c and silcd/idlist.h.
358 * Added silc_task_unregister_by_context into the file
359 lib/silcutil/silctask.[ch].
361 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added SILC_UMODE_GONE mode to indicate when the client is not
364 present in the SILC network. Added also support to the local
365 command AWAY that will set this mode. Added support of showing
366 "xxx is gone" in WHOIS command. The USERS command shows the
369 * Fixed setting server and router operator privileges in the
370 server's UMODE command. Affected file silcd/command.c.
372 * Merged the SKE KE1 and KE2 payloads into one payload. The
373 new KE payload is equivalent to the old KE2 payload.
375 Cleaned up the SKE Start Payload parsing. It now uses the
376 simple buffer unformatting to do the parsing. A lot faster
379 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
380 to the SKE that is used to indicate whether both of the SKE
381 parties should perform authentication. By default only the
382 responder performs authentication. By setting this flag also
383 the initiator must do authentication. By default it is unset
384 since in normal SKE case, client to server connection, only
385 the responder should do authentication. When doing SKE between
386 two clients both should perform authentication. Updated the
387 code and the protocol specs.
389 * A little fix to IDENTIFY command in the server. Search the
390 client first by hash not nickname. Affected file is
393 * Fixed the silc_client_close_connection to support closing
394 the client to client connections wihtout deleting too much
395 data. Affected file lib/silcclient/client.c.
397 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
398 are received if protocol used to be active but is not anymore
399 the application would crash due to NULL pointer dereference.
400 Affected files silcd/server.c and lib/silcclient/client.c.
402 * Added `hash' field to the SilcClientConnection to include
403 the hash function negotiated in the SKE protocol.
405 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
406 to set the channel founder authentication data. A client can
407 claim the founder rights later by providing the authentication
408 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
409 This way the channel founder can regain the channel founder
410 privileges even it is left the channel. This works only on
411 local server and the client must be connected to the same
412 server to be able to regain the founder rights. Updated the
413 protocol specs accordingly.
415 Added support to the CMODE command in the client to set the
416 founder auth data. Read the README to see how to set it.
418 Added support to the CUMODE command to claim the founder
419 rights. Read the README to see how to do it.
421 Added support for the founder authentication to the Channel
422 Entry in the server. Affected file silcd/idlist.h.
424 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
425 server's CMODE command. Affected file silcd/command.c.
427 * Added the following new functions into lib/silccore/silcauth.[ch]:
428 silc_auth_get_method and silc_auth_get_data.
430 * The server now saves the remote hosts public key to the
431 SilcIDListData pointer. Affected file silcd/protocol.c.
433 * The normal server now does not remove the channel entry from
434 the cache if the founder authentication data is set. It used
435 to remove it if the founder was the last one on the channel on
436 the server and left the channel. The auth data is saved and
437 if the channel is re-joined later the old entry is used with
438 the old auth data. Affected files silcd/command_reply.c and
441 * Removed the `pkcs' field from the SilcIDListData structure
442 in the server; it is not used. Affected file silcd/idlist.h.
444 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
446 * Fixed packet processing on slow links. Partial packets were
447 never re-processed because the incoming data buffer was cleared
448 by the application. Application must not directly clear the
449 sock->inbuf, the packet processing routines handle it. Fixed
450 this in client library and in server.
452 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed the WHOIS and IDENTIFY send reply function to really
455 check whether to send list or just one entry. Affected file
458 * Cleaned up the LEAVE command's channel key distribution. The
459 affected file silcd/command.c.
461 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
462 can enforce the channel mode as well. In that case the ID
463 includes the ID of the server. The code now enforces the
464 mode change if the router have different mode than the server.
466 * The notify client operation with CMODE_CHANGE notify can now
467 return NULL client_entry pointer if the CMODE was not changed
468 by client. Application must check for this.
470 * Added <Server ID> argument to INFO command to support server
471 info fetching by Server ID.
473 * Added silc_server_announce_get_channel_users to get assembled
474 packets of channel users of the specified channel. Affected
475 file silcd/server.[ch].
477 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
478 was freed underneath the ID Cache.
480 * Re-announce clients when the server received CHANNEL_CHANGE
481 notify from the router. Affected file silcd/packet_send.c.
483 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
485 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
486 crashed since it did not handle the fact that there is no cipher
487 called "3" and didn't check the error condition. Now fixed.
489 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
490 flag. It can be used to send message requests.
492 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Implemented the RESTART command in the client.
496 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
497 notice type messages. Added notice printing to the user
500 * The channel keys are not re-generated if the channel's mode
501 is PRIVKEY, ie private key on the channel exists. Affected
502 files silcd/server.c and silcd/command.c.
504 * Fixed a little bug in channel message delivery when channel
505 private keys are set in the server. Affected file is
508 * Changed the setting on channel->on_channel = TRUE from the
509 silc_client_save_channel_key to the JOIN command reply. The
510 key payload is not received if the private channel key is set.
511 Affected file lib/silcclient/command_reply.c and the
512 lib/silcclient/client_channel.c.
514 * When the CMODE_CHANGE notify is sent and the channel private
515 key mode is removed the channel key must be re-generated in
516 other cells as well. Added this support for the router in the
517 silcd/packet_receive.c.
519 * Added new local command NOTICE to send notice message on
520 channel. Affected file silc/local_command.[ch].
522 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Added new local command ME to the client. It is used to send
525 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
526 some action. Affected file silc/local_command.[ch].
528 * Changed channel_message and private_message client operations
529 to deliver the message flags to the application. Added also
530 the `flags' arguments to the silc_client_send_channel_message
531 and silc_client_send_private_message functions. Affected file
534 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Redefined the Private Message Payload to support private message
537 keys and to support the new private message flags. Updated
538 the protocol specs. Flags makes it possible to have for example
541 * Added new type SilcPrivateMessagePayload and defined an API
542 for it in the lib/silcclient/silcprivate.[ch].
544 * Tested private message private keys successfully. Tested the
545 private message key set, unset and list commands with the new
548 * Redefined the Channel Message Payload to include the channel
549 message flags (equal with private message flags) to support
550 for example CTCP style messages.
552 * Defined some of the message (for channel and private message)
553 flags. Updated the protocol specs and added the flags to the
554 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
556 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Added SilcKeyAgreementStatus type to the key agreement routines
559 to indicate the current status and error if one occured.
560 The status types are defined in the lib/silcclient/silcapi.h.
562 * Added new local command KEY that is used to set and unset private
563 keys for channels, set and unset private keys for private messages
564 with remote clients and to send key agreement requests and
565 negotiate the key agreement protocol with remote client. The
566 key agreement is supported only to negotiate private message keys,
567 it currently cannot be used to negotiate private keys for channels,
568 as it is not convenient for that purpose.
570 * Fixed a minor pending callback setting bug in the function
571 silc_client_get_client_by_id_resolve, now the function works.
572 Affected file lib/silcclient/idlist.c.
574 * Added function silc_net_get_local_port to get local bound
575 port by socket. Added to lib/silcutil/silcnet.[ch].
577 * Added `sockets' and `sockets_count' fields to the SilcClient
578 object. They hold the sockets of the listenning sockets in
579 the client. Listenning sockets may be for example the key
580 agreement server. Affected file lib/silcclient/client.[ch].
581 Added functions the silc_client_add_socket and the
582 silc_client_del_socket. They are exported to the application
585 * Added ~./silc/clientkeys to support other client's public keys.
587 * Renamed verify_server_key client operation to verify_public_key
588 and added one argument to indicate the type of the connection
589 (server, client etc.).
591 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
593 * Added silc_server_connection_auth_request to handle the
594 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
595 silcd/packet_receive.[ch].
597 * Added silc_server_send_connection_auth_request into the
598 silcd/packet_send.c to send the connection auth request packet.
600 * Cleaned up the silcd/protocol.c a bit and fixed some memory
603 * Fixed the public key authentication in responder side in the
604 server. The `auth_data' pointer includes the SilcPublicKey
605 not the path to the public key. Affected file silcd/protocol.c.
607 * Implemented the public key authentication in the initiator side
608 in the server. Affected file silcd/protocol.c.
610 * Removed the [RedirectClient] config section from the server
611 configuration. Is not needed and I don't want to implement it.
613 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Cleaned up the CMODE command in the server. It now works
616 correctly and supports all the modes defined in the protocol.
617 Affected file is silcd/command.c.
619 * Added `hmac_name' field to the SilcChannelEntry in the server
620 to hold the default HMAC of the channel. It can be set when
621 creating the channel (with JOIN command). Affected files
624 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
625 type to indicate the change of the current cipher and hmac
626 on the channel. Client can safely ignore the <cipher> argument
627 (if it chooses to do so) since the CHANNEL_KEY packet will
628 force the channel key change anyway. The <hmac> argument is
629 important since the client is responsible of setting the new
630 HMAC and the hmac key into use.
632 * Fixed the CMODE command in the client library as well.
634 * Tested CMODE command in router environment successfully.
636 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Show the version of the remote client (or server) when connecting
639 to the server. It is logged to the log file. Affected file
642 * Fixed the KILLED notify handling in the client library. The
643 client must be removed from all channels when receiving the
646 Also, do not remove the client entry when giving the KILL
647 command but when the KILLED notify is received.
649 * Removed silc_idlist_find_client_by_nickname from the server.
650 Not needed anymore. Affected files silcd/idlist.[ch].
652 * Implemented the CHANNEL_CHANGE notify type handling to the
653 server. Affected file silcd/server.c.
657 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Added silc_server_send_notify_invite to send the INVITE
660 notify between routers.
662 * Implemented the INVITE command correctly to the server.
664 * Implemented the INVITE notify type handling in the server.
666 * Implemented the INVITE command to the client library and on the
669 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Added function silc_server_get_client_resolve to find the
672 client entry by ID from all ID lists and then resolve it
673 (using WHOIS) if it cannot be found. Affected file is
676 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
678 * Implemented the BAN command to the client library.
680 * The JOIN command in the server now checks the invite list
683 * Changed the silc_command_reply_payload_encode_va and the
684 silc_command_payload_encode_va to support that if argument is
685 NULL it ignores and checks the next argument. Affected file
686 lib/silccore/silccommand.c.
688 * Added silc_server_send_notify_ban to send the BAN notify
689 type between routers.
691 * Chaned the silc_notify_payload_encode to support that if
692 argument is NULL it ignores and checks the next argument.
693 Affected file lib/silccore/silcnotify.c.
695 * Tested ban lists in router environment successfully.
697 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Implemented BAN command to the server, in silcd/command.[ch].
701 * Removed the BAN and INVITE_LIST modes from the CMODE command
704 * Added function silc_string_match to regex match two strings.
705 Affected files lib/silcutil/silcutil.[ch].
707 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Redefined parts of the SilcChannelEntry in the server to support
710 the new ban and invite lists.
712 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Redefined the INVITE command. The same command can be used to
715 invite individuals to the channel but also to manage the invite
716 list of the channel (to add to and remove from the invite list).
717 Updated the protocol specs.
719 * Added new command SILC_COMMAND_BAN that can be used to manage
720 the ban list of the channel. Updated the protocol specs.
722 * Removed the channel modes: the SILC_CMODE_BAN and the
723 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
724 in the CMODE command. The equivalent features are now available
725 using INVITE and BAN commands. Updated the protocol specs.
727 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
728 in the network about change in the current ban list. The notify
729 type is not used by the client.
731 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
732 support the invite lists.
734 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Added new function silc_string_regexify that converts string
737 including wildcard characters into regex string that can
738 be used by the GNU regex library. Added into the file
739 lib/silcutil/silcutil.[ch].
741 Added silc_string_regex_combine to combine to regex strings
742 into one so that they can be used as one regex string by
743 the GNU regex library. Added into the file
744 lib/silcutil/silcutil.[ch].
746 Added silc_string_regex_match to match two strings. It returns
747 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
749 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Imported GNU regex to the soruce tree into lib/contrib.
752 Fixed some compiler warning from the regex.c.
754 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Fixed MOTD command in the server to work in router environment.
758 * Fixed the MOTD command in the client library to support
759 the server argument in the command.
761 * Added `nickname_len' argument to the silc_idlist_add_client
762 in the server, as the `nickname' argument may be binary data
765 * Added silc_idlist_get_channels to return all channels from
768 * Implemented LIST command to the server. Affected file is
771 * Implemented the LIST command to the client library and on the
774 * Added [<user count>] argument to the LIST command reply.
775 With private channels the user count is not shown.
777 * Updated TODO and README.
779 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * The client entry's data.registered must be TRUE even with
782 global client entry on global client list. The data.registered
783 is used to check whether the client is anymore in the network,
784 for example with WHOWAS command so it must be valid.
786 * Fixed the WHOWAS command in the server. It now actually works
787 in router environment. Added function into silcd/command_reply.c
788 silc_server_command_reply_whowas_save.
790 * Added silc_idlist_purge function to the silcd/idlist.c
791 to periodically purge the ID Cache.
793 * Fixed INFO command in the server. It works now in router
794 environment. Added <server name> argument to the INFO command
795 reply. Updated the protocol specs.
797 * Fixed minor bug in silc_idcache_purge to not purge if the
798 expire value is zero.
800 * Fixed various bugs in WHOIS and IDENTIFY command handling as
801 they were buggy because of the WHOWAS information.
803 * Fixed local command MSG to handle the async resolving of
804 the remote client properly. It used to fail the first MSG.
805 Affected file silc/local_command.c.
807 * Added `data_len' field to SilcIDCache context.
809 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Update TODO. Todo in commands in the server.
813 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
816 used by routers as broadcast packet to inform other routers
817 about the changed user mode.
819 Implemented the notify handling in the server. Affected file is
820 silcd/packet_receive.c. Added the function
821 silc_server_send_notify_umode to the silcd/packet_send.[ch].
823 * Added new generic Channel Payload and deprecated the New Channel
824 Payload. The New Channel Payload is now the generic Channel
827 * Added new argument `mode' to the silc_server_send_new_channel
828 as it is required in the Channel Payload now.
830 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
831 and created a new and real SilChannelPayload to represent the
832 new generic Channel Payload. Implemented the encode/decode
833 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
835 * Added silc_server_get_client_channel_list to return the list
836 of channels the client has joined for WHOIS command reply.
837 Affected file silcd/server.[ch].
839 * Implemented the channel list sending in the WHOIS command reply
840 in server and in the client.
842 Implemented the channel list displaying on the user interface
843 as well. Affected file silc/client_ops.c.
845 * Added silc_channel_payload_parse_list to parse list of Channel
846 Payloads. It returns SilcDList list of SilcChannelPayloads.
847 Client for example can use this function to parse the list of
848 channels it receives in the WHOIS command reply. The caller
849 must free the list by calling silc_channel_payload_list_free.
850 Affected files lib/silccore/silcchannel.[ch].
852 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Added one new argument <user mode> to the WHOIS command reply
855 to return the mode of the user in SILC. Updated the protocol
858 Implemented it to the server and client.
860 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Fixed the mode printing on the user interface on joining.
863 Affected file silc/client_ops.c.
865 * Implemented the UMODE command and user modes in general to the
866 client library and to the user interface.
868 * Implemented the UMODE command to the server.
870 * The server now sends UNKNOWN_COMMAND error status if client sends
871 unknown command. Affected file silcd/command.c.
873 * All server commands now handle the command identifier the right
874 way when sending the command reply to the client. The client can
875 use to identify the command replies with the identifier.
877 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Added silc_server_get_client_route to resolve the route to
880 the client indicated by the client ID. Affected file is
883 * Added silc_server_relay_packet as general function to relay
884 packet to arbitrary destination. This deprecates functions
885 like _send_private_message_key, _relay_notify etc. Affected
886 file is silcd/packet_send.[ch].
888 Removed silc_server_send_key_agreement,
889 silc_server_send_private_message_key and
890 silc_server_packet_relay_notify functions from the file
891 silcd/packet_send.[ch].
895 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
896 server. Affected file silcd/packet_receive.[ch].
898 * Implemented the KILL command to the client. Implemented the
899 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
900 Affected files lib/silcclient/command[_reply].c and
901 lib/silcclient/client_notify.c. Implemented the KILL notify
902 printing in the user inteface.
904 * Fixed a lot silc_parse_nick memory leaks from the client
905 library in the file lib/silcclient/command.c.
907 * Changed the silc_server_send_notify_on_channels's `sender'
908 argument from SilcSocketConnection to SilcClientEntry to
909 check the sender as entry and not as connection object and not
910 to send to the client provided as argument. The affected file
911 is silcd/packet_send.[ch].
913 * The notify packets that are destined directly to the client used
914 to not to be processed by the server. Now changed that and the
915 server processes all notify packets. After relaying the packet
916 to the client the notify packet is processed in the server.
918 * The silc_server_free_client_data now checks whether there is
919 pending outgoing traffic for the client and purges the data to
920 the network before removing the client entry.
922 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
925 an client is killed from the SILC Network. Updated the protocol
928 Added new function silc_server_send_notify_killed to the
929 silcd/packet_send.[ch].
931 * Added function silc_server_packet_relay_notify to relay notify
932 packets that are destined directly to a client. In this case
933 the server does not process the notify packets but merely relays
934 it to the client. Affected file silcd/packet_send.[ch].
936 Added also silc_server_packet_process_relay_notify to check
937 whereto relay the notify. Affected file is
938 silcd/packet_receive.[ch].
940 * Implemented the KILL command to the server.
944 * Added the backup schema desgined last fall to the protocol
945 specs for everyone to see. The specification is in the
946 *-spec-xx.txt draft and the packet type definitions for the
947 backup routers is in *-pp-xx.txt draft. Thusly, added also
948 new packet type SILC_PACKET_CELL_ROUTERS.
950 * A big security problem in the implementation discovered. The
951 signoff of an client did not cause new channel key generation
952 which it of course should've done. The channel keys must be
953 always re-generated when client leaves (or signoffs) the channel.
954 The silc_server_remove_from_channels funtion now handles
955 the channel key re-generation.
957 * Added `sender' argument to the silc_server_send_notify_on_channels
958 to not to send the client provided as argument. Affected file
959 silcd/packet_send.[ch].
961 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Implemented OPER and SILCOPER commands into the server and
966 * Added silc_auth_verify and silc_auth_verify_data to verify
967 the authentication directly from the authentication payload.
968 It supports verifying both passphrase and public key based
969 authentication. Affected file lib/silccore/silcauth.[ch].
971 * Added `hash' field to the SilcIDListData structure. It is the
972 hash negotiated in the SKE protocol. Affected file is
975 * Slight redesigning of the SilcAuthPayload handling routines.
976 Do not send SilcPKCS but SilcPublicKey as argument.
978 * Implemented the public key authentication support to the
979 serverconfig. The public key is loaded from the provided path
980 and saved as authentication data to void * pointer. Thus,
981 changed the unsigned char *auth_data to void *auth_data;
983 * Fixed SHUTDOWN command to send the reply before the server
984 is shutdown. :) Affected file silcd/command.c.
986 * Fixed fatal bug in CONNECT command. The hostname was invalid
987 memory and server crashed. Affected file silcd/command.c.
989 * Fixed fatal bug in CLOSE command. The server_entry became
990 invalid but was referenced later in the command. Affected file
993 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Fixed fatal bug in failure packet handling. Server ignored
996 the failure and thus crashed when it came.
1000 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1003 that the command may be executed only once in (about) 2 seconds.
1004 The old SILC_CF_LAG flag is same but allows command bursts up
1005 to five before limiting.
1007 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1008 server code. Various commands now includes the CF_LAG_STRICT
1009 flag to disallow any kind of miss-use of the command.
1011 * Fixed the silc_buffer_unformat to not to allocate any data
1012 if the length of the data is zero. It used to allocate the
1013 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1015 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * Changed the format of AdminConnection configuration section
1018 in the server. Added username of the admin to the format.
1019 Affected files silcd/serverconfig.[ch].
1021 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1022 to return admin configuration data by host, username and/or
1025 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Implemented WHOWAS command to the server. Added the functions:
1029 silc_server_command_whowas_parse,
1030 silc_server_command_whowas_send_reply,
1031 silc_server_command_whowas_from_client and
1032 silc_server_command_whowas_from_server
1034 * Added <Client ID> argument to the WHOWAS command reply. Updated
1035 the protocol specs accordingly.
1037 * Implemented WHOWAS command and command_reply to the client
1040 Implemented the WHOWAS printing on the user interface.
1042 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * Added new argument to the WHOWAS command reply, the real name.
1045 It is an optional argument. Updated the protocol specs.
1047 * Added SilcIDCacheDestructor callback that is registered when
1048 the SilcIDCache is allocated. The callback is called when
1049 an cache entry in the ID Cache expires, or is purged from the
1050 cache. Added into lib/silccore/idcache.[ch].
1052 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1053 to destruct the client entries when the cache entry expires.
1054 Other ID Cache's in server and in the client library ignores
1057 * If the ID Cache entry's `expire' field is zero then the entry
1058 never expires. Added boolean `expire' argument to the
1059 silc_idcache_add function in the lib/silccore/idcache.[ch].
1060 If it is TRUE the default expiry value is used.
1062 * Added silc_server_free_client_data_timeout that is registered
1063 when client disconnects. By default for 5 minutes we preserve
1064 the client entry for history - for WHOWAS command.
1066 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Added support to the server to enforce that commands are not
1069 executed more than once in 2 seconds. If server receives
1070 commands from client more frequently, timeout is registered
1071 to process the commands. Affected file silcd/command.c.
1072 Added new function silc_server_command_process_timeout.
1074 * Changed NICK_NOTIFY handling in client library to check that
1075 if the client's nickname was changed, so there is no need to
1076 resolve anything from the server.
1078 * Removed error printing from the WHOIS and IDENTIFY commands.
1079 If error occurs then it is ignored silently in the client library.
1080 The application, however, may map the received error to
1081 human readable error string. The application currently maps
1082 the NO_SUCH_NICKNAME error to string.
1084 * Made the command status message public to the application. Moved
1085 them from lib/silcclient/command_reply.c to
1086 lib/silcclient/command_reply.h. The application can map the
1087 received command status to the string with the
1088 silc_client_command_status_message function.
1090 * Added check to the server to check that client's ID is same
1091 as the Source ID in the packet the client sent. They must
1094 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Added dist-bzip hook to the Makefile.am to make bzip2
1097 compressed distributions.
1099 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Server now enforces the maximum length for the nickname and
1102 the channel as protocol specification dictates. 128 bytes for
1103 nickname and 256 bytes for channel name.
1105 * Moved the WHOIS printing to the application. The client libary
1106 does not print out the WHOIS information anymore, the application
1107 must do it. Renamed silc_client_command_reply_whois_print to
1108 the silc_client_command_reply_whois_save.
1110 The client's idle time is also sent to the application now, and
1111 the idle is shown on screen.
1113 * Added silc_client_command_reply_identify_save to save the
1114 received IDENTIFY entries.
1116 * Do not check for channel private keys in message sending and
1117 reception if the channel does not have the PRIVKEY mode set.
1118 Affected file lib/silclient/client_channel.c.
1120 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1123 just surfaced after chaning the JOIN procedure.
1125 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Added silc_client_get_clients_by_list to get client entries
1128 from Client ID list, that is returned for example by JOIN
1129 and USERS command replies. The application should use this
1130 function for example when JOIN command reply is received to
1131 resolve the clients already on the channel (library does not
1132 do that anymore as USERS command reply is not used in the JOIN
1133 procedure anymore). Affected files lib/silcclient/silcapi.h and
1134 lib/silcclient/idlist.c.
1136 * JOIN command reply and USERS command reply returns now SilcBuffer
1137 pointers instead of unsigned char pointers when returning
1138 the client list and mode list.
1140 * Added <Client ID> argument to the JOIN command reply, mainly
1141 for the server to identify for which client the command was
1142 originally sent. Updated protocol specs accordingly.
1144 * Added SilcDlist private_key pointer to the SilcChannelEntry
1145 in the client to support the channel private keys. Affected
1146 file is lib/silcclient/idlist.h.
1148 * Added SilcChannelPrivateKey argument to the function
1149 silc_client_send_channel_message so that application can choose
1150 to use specific private ke if it wants to. If it is not provided,
1151 the normal channel key is used, unless private keys are set.
1152 In this case the first (key that was added first) is used
1153 as the encryption key.
1155 * Implemented the support for channel private key handling.
1156 Implemented the following functions:
1158 silc_client_add_channel_private_key,
1159 silc_client_del_channel_private_keys,
1160 silc_client_del_channel_private_key,
1161 silc_client_list_channel_private_keys and
1162 silc_client_free_channel_private_keys
1164 Affected file lib/silcclient/client_channel.c.
1166 * Added the support for the private keys in the channel message
1167 sending and encryption and in the message reception and
1168 decryption. Affected funtions are
1169 silc_client_send_channel_message and silc_client_channel_message.
1171 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added SKE's key verify callback to the client library's
1174 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1176 * Removed the statement that server (or router) must send USERS
1177 command reply when joining to the channel so that the client
1178 knows who are on the channel. Instead, the client list and
1179 client's mode list is now sent in the JOIN command reply to the
1180 client who joined channel. This is better solution.
1182 * Added function silc_server_get_users_on_channel and function
1183 silc_server_save_users_on_channel to the silcd/server.[ch].
1185 * Removed function silc_server_command_send_users from the
1188 * Do not show topic on the client library anymore. The topic is
1189 sent in the command reply notify to the application and the
1190 application must show the topic now.
1192 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added client searching by nickname hash into the IDENTIFY and
1195 WHOIS commands in the server as they were clearly missing from
1196 them. Affected file is silcd/command.c.
1198 * Fixed a bug in private message receiving in the client library.
1199 The remote ID was freed and it wasn't supposed, now it is
1202 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Minor fix to the channel payload; allocate the data area, as it
1205 needs to be of specific length.
1207 * If the key agreement port is zero then the operating
1208 system will define the bound port. Affected files are
1209 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1211 * Added new function silc_channel_payload_decrypt into the file
1212 lib/silccore/silcchannel.[ch].
1214 * Moved the channel message etc, check from silc_packet_decrypt
1215 to applications. The library calls now a generic
1216 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1217 when the packet is either normal or special. This was done to
1218 allow more wide range of checking that was not allowed when
1219 the code was in library. Now applications can do virtually any
1220 checks to the packet and return to the library the decision how
1221 the packet should be processed. Affected files are
1222 lib/silccore/silcpacket.[ch].
1224 Added silc_server_packet_decrypt_check to the server and
1225 silc_client_packet_decrypt_check to the client library.
1227 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1228 to send with specified source and destination information.
1230 * Channel message delivery between routers was broken after the
1231 channel key distribution was fixed earlier. The channel key
1232 was used be to distributed to other routers as well which is not
1233 allowed by the protocol. Now this is fixed and channel keys
1234 really are cell specific and the channel message delivery between
1235 routers comply with the protocol specification.
1237 * Fixed various commands in server to check also the global list
1238 for the channel entry and not just the local list. The affected
1239 file silcd/command.c.
1241 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Added assert()s to buffer formatting and unformatting routines
1244 to assert (if --enable-debug) when error occurs. Affected
1245 file: lib/silcutil/silcbuffmt.c.
1247 * Changed to auto-reconnect to check whether the remote host is
1248 router and register the re-connect timeout if it is. It used
1249 to check that whether we are normal server, but router must do
1250 auto-reconnect with another router as well. Affected file
1253 * Removed the [<key len>] option from CMODE command as the cipher
1254 name decides the key length, nowadays. See the defined ciphers
1255 from the protocol specification.
1257 * Added [<hmac>] option to the CMODE command to define the HMAC
1258 for the channel. Added SILC_CMODE_HMAC channel mode.
1260 * Added [<hmac>] option for the JOIN command so that user can
1261 select which HMAC is used to compute the MACs of the channel
1264 * Added Hmac field to the Channel Message Payload. The integrity
1265 of plaintext channel messages are now protected by computing
1266 MAC of the message and attaching the MAC to the payload. The
1267 MAC is encrypted. Now, it is clear that this causes some
1268 overhead to the size of the packet but rationale for this is that
1269 now the receiver can verify whether the channel message decrypted
1270 correctly and also when private keys are set for the channel the
1271 receiver can decrypt the packet with several keys and check from
1272 the MAC which key decrypted the message correctly.
1274 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1275 lib/silccrypt/silccipher.[ch].
1277 * Added silc_hash_len to return the digest length into the
1278 lib/silcrypt/silchash.[ch].
1280 * Rewrote parts of Silc Channel Payload interface in the
1281 lib/silccore/silcchannel.[ch]. The encode function now also
1282 encrypts the packet and parse function decrypts it.
1284 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Fixed a minor formatting bug in the SKE's key material processing.
1287 It actually might have processed the keys wrong way resulting
1290 * Redefined the mandatory HMAC algorithms and added new algorithms.
1291 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1292 and hmac-md5 truncated to 96 bits. The mandatory is now
1293 hmac-sha1-96. Rest are optional (including the one that used
1294 to be mandatory). Rationale for this is that the truncated HMAC
1295 length is sufficient from security point of view and can actually
1296 make the attack against the HMAC harder. Also, the truncated
1297 HMAC causes less overhead to the packets. See the RFC2104 for
1300 * Added new [hmac] configuration section. The SKE used to use
1301 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1302 is of course wrong. The official names that must be proposed in
1303 the SKE are the ones defined in the protocol specification
1304 (hmac-sha1-96 for example). The user can configure any hmac
1305 using any hash function configured in the [hash] section. At
1306 least, the mandatory must be configured.
1308 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1310 * Added HMAC list to the SKE proposal list. It has now both
1311 hash algorithm list and HMAC list. This makes the protocol
1312 incompatible with previous versions. The SKE now seems to work
1313 the way it is supposed to work, for the first time actually.
1315 * Defined plain Hash algorithms to the protocol specification.
1318 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Implemented support for key agreement packets into the server.
1321 Added functions silc_server_key_agreement and
1322 silc_server_send_key_agreement. Other than these functions,
1323 server has nothing to do with this packet.
1325 * Added support for private message key packets into the server.
1326 Added functions silc_server_private_message_key and
1327 silc_server_send_private_message_key.
1331 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1332 called in the protocol's final callback instead in the END
1333 protocol state. This makes a little more sense and in the same
1334 time in client we can use the same protocol routines for normal
1335 key exchange and to key agreement packet handling as well.
1337 * Added to both client's and server's KE protocol context the
1338 SilcSKEKeyMaterial pointer to save the key material. We will
1339 bring the key material to the protocol's final callback by doing
1340 this. The final callback must free the key material.
1342 * Added SKE's packet_send callback into client's KE protocol
1343 context so that the caller can choose what packet sending function
1344 is used. This way we can use different packet sending when
1345 doing normal SKE when doing key agreement packet handling (in
1346 the key agreement packet handling we do not want to encrypt
1349 * Implemented the responder side of the key agreement routines
1350 in the client. The client can now bind to specified port and
1351 accept incoming key negotiation. The key material is passed
1352 to the application after the protocol is over.
1354 * Implemented the processing of incoming Key Agreement packet
1355 in the client. Added function silc_client_key_agreement to
1358 * Implemented the intiator side of the key agreement routines
1359 in the client. The client can now initiate key agreement with
1360 another remote client. The key material is passed to the
1361 application after the protocol is over.
1363 * Created client_keyagr.c to include all the key agreement
1366 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1367 SILC_TASK_CALLBACK except that it is not static.
1369 * Created client_notify.c and moved the Notify packet handling
1370 from the client.[ch] into that file.
1372 * Created client_prvmsg.c and moved all private message and
1373 private message key routines from the client.[ch] into that file.
1375 * Create client_channel.c and moved all channel message and
1376 channel private key routines from the client.[ch] into that file.
1378 * Changed silc_client_get_client_by_id_resolve to resolve with
1379 WHOIS command instead of IDENTIFY command, in the file
1380 lib/silclient/idlist.c.
1382 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Implemented the SKE's responder side to the Client library.
1386 * When FAILURE is received to the protocol do not trust it
1387 blindly. Register a timeout to wait whether the remote closes
1388 the connection as it should do it, only after that process the
1389 actual failure. This was changed to both client and server.
1391 * Added client_internal.h to include some of the structures
1392 there instead of client.h in lib/silcclient/.
1394 * Added function silc_task_unregister_by_callback to unregister
1395 timeouts by the callback function.
1397 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1399 * Some "Incomplete WHOIS info" errors has been appearing on the
1400 log files. Took away the entry->userinfo check from WHOIS
1401 reply sending. The entry->userinfo is now " " if client did not
1402 provide one. I thought this was fixed earlier but something
1403 is wrong still. Let's see if the error still appears.
1405 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Fixed a minor bug in the login when the channel key is
1408 re-generated in the server. It used to generate the key in
1409 wrong order and thus caused problems in the channel traffic.
1411 * Fixed a minor bug in channel key distsribution after
1412 KICK command. The key was not sent to the router even though
1415 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * Added silc_ske_process_key_material_data as generic routine
1418 to process any key material as the SILC protocol dictates. The
1419 function is used by the actual SKE library but can be used by
1420 applications as well. This relates to the private message keys
1421 and the channel private keys since they must be processed the
1422 same way the normal SILC session keys. The protocol dictates
1423 this. Affected files: lib/silcske/silcske.[ch].
1425 Added also silc_ske_free_key_material to free the
1426 SilcSKEKeyMaterial structure.
1428 * Defined silc_cipher_set_key function to set the key for
1429 cipher without using the object's method function. The affected
1430 files: lib/silccrypt/silccipher.[ch].
1432 * Implemented silc silc_client_add_private_message_key,
1433 silc_client_add_private_message_key_ske,
1434 silc_client_del_private_message_key,
1435 silc_client_list_private_message_keys and
1436 silc_client_free_private_message_keys functions in the
1439 Added functions silc_client_send_private_message_key to send
1440 the Private Message Key payload and silc_client_private_message_key
1441 to handle incoming Private Message Key payload.
1443 * Added Cipher field to the Private Message Key payload to set
1444 the cipher to be used. If ignored, the default cipher defined
1445 in the SILC protocol (aes-256-cbc) is used.
1447 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Removed lib/silcclient/ops.h file.
1451 Redefined parts of the SILC Client Library API. Created new
1452 file silcapi.h that deprecates the ops.h file and defines the
1453 published Client Library API. Defined also private message key
1454 API and channel private key API into the file.
1456 This is the file that the application must include from the
1457 SILC Client Library. Other files need not be included by
1458 the application anymore.
1460 * Added new key_agreement client operation callback and also
1461 defined the Key Agreement library API for the application.
1463 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1466 is used by clients to request key negotiation between another
1467 client in the SILC network. If the negotiation is started it
1468 is performed using the SKE protocol. The result of the
1469 negotiation, the secret key material, can be used for example
1470 as private message key.
1472 Implemented the Key Agreement payload into the files
1473 lib/silccore/silauth.[ch].
1475 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Redefined ciphers for the SILC protocol. Added some new ciphers
1478 and defined the key lengths for the algorithms. Changed the
1479 code accordingly. The default key length is now 256 bits.
1481 * Fixed SKE key distribution function silc_ske_process_key_material
1482 when the key length is more than 128 bits. The default key
1483 length in SILC is now 256 bits.
1485 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1486 to indicate unsupported algorithm.
1488 * Renamed rijndael.c to aes.c and all functions as well.
1490 * Fixed a long standing channel key setting bug in client library.
1491 Weird that it has never surfaced before.
1493 * Fixed bug in channel deletion. If the entire channel is removed
1494 then it must also delete the references of the channel entry
1495 from the client's channel list as the client's channel entry and
1496 the channel's client entry share same memory.
1498 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Implemented CONNECT and SHUTDOWN commands in the client.
1502 * Implemented CLOSE command to the client.
1504 * Added the function silc_idlist_find_server_by_name into the
1505 files silcd/idlist.[ch].
1507 Added the function silc_idlist_find_server_by_conn into the
1508 files silcd/idlist.[ch].
1510 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * DIE command was renamed to SHUTDOWN. Updated the both code
1515 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1516 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1518 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1521 * Added function silc_server_create_connection function to create
1522 connection to remote router. My server implementation actually
1523 does not allow router to connect to normal server (it expects
1524 that normal server always initiates the connection to the router)
1525 so the CONNECT command is only good for connecting to another
1528 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1531 or some other client was kicked from the channel.
1533 Implemented the handling of the notify type to both client
1536 Implemented silc_server_send_notify_kicked to send the KICKED
1537 notify. It is used to send it to the server's primary router.
1539 * Implemented the KICK command into server and client.
1541 * Added `query' argument to the silc_idlist_get_client function
1542 to indicate whether to query the client from server or not if
1545 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1546 to indicate that the client is not channel founder.
1550 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Removed the rng context from SilcPacketContext structure and
1553 changed that the packet routine uses the Global RNG API.
1555 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * Added support for quit message that client can "leave" on the
1558 channel when it quits the SILC. It is ditributed inside the
1559 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1561 Added silc_server_free_client_data that will take the
1562 signoff message as argument.
1564 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1566 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Updated parts of the protocol specification to keep it up
1571 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1574 payloads in one packet.
1576 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1577 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1578 use now the new List flag.
1580 * Also deprecated the following packet types: REPLACE_ID,
1581 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1583 * Added list support for Notify packet in server.
1585 * Added silc_server_send_notify_channel_change to send the
1586 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1587 the silc_server_send_replace_id.
1589 * Added silc_server_send_notify_nick_change to send the
1590 NICK_CHANGE notify type. Deprecates the function
1591 silc_server_send_replace_id.
1593 * Added silc_server_send_notify_join to send the JOIN notify type.
1594 Deprecates the function silc_server_send_new_channel_user.
1596 * Added silc_server_send_notify_leave to send LEAVE notify type.
1597 Deprecates the function silc_server_send_remove_channel_user.
1599 * Added silc_server_send_notify_cmode and
1600 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1601 types. Deprecates the silc_server_send_set_mode function.
1603 * Added SERVER_SIGNOFF notify type to indicate that server has
1604 quit. This means that all clients on the channel from that
1605 server will drop. This can be also used when netsplit happens.
1607 Deprecated REMOVE_ID packet type since it is not needed anymore
1610 Added silc_server_send_notify_server_signoff to send the
1611 SERVER_SIGNOFF notify type. Deprecates the function
1612 silc_server_send_remove_id.
1614 Added also silc_server_send_notify_signoff to send the
1615 SIGNOFF notify type.
1617 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1618 SILC protocol from this day on. Changed the protocol
1619 specification as well.
1621 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1622 notify type. It is used between routers to notify about
1623 topic changes on a channel.
1625 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1628 * Partly updated the protocol specification to comply with the
1629 changes now made. It is still though a bit outdated.
1631 * The JOIN notify type now takes one extra argument <Channel ID>.
1632 The packet used to be destined to the channel but now the
1633 JOIN type may be sent as list thus it is impossible to
1634 destine it to any specific channel. By adding this argument
1635 it is again possible.
1637 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Added CREDITS file. The CHANGES and CREDITS file will appear
1640 in the distribution as well.
1642 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1645 types in the server's silcd/packet_receive.c.
1647 * Implemented CMODE and CUMODE to work in router environment.
1649 * Fixed minor encoding and decoding buglet from the
1650 lib/silccore/silcmode.c.
1652 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1655 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1657 * Changed all SilcConfigServer* and silc_config_server* to
1658 SilcServerConfig* and silc_server_config*, respectively.
1661 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Associated the ID (client or server ID) to the Authentication
1664 Payload to avoid any possibility of forging. Updated the
1665 protocol specification and the code accordingly.
1667 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * The RSA key length is now save to the RsaKey context in the
1670 key generation process in lib/silccrypt/rsa.c. The key length
1671 is now used to figure out the maximum size of the block allowed
1672 to be encrypted/signed.
1674 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1675 is equivalent to the silc_mp_mp2bin but does not allocate any
1678 * Changed silc_mp_mp2bin API to take length argument. If it is
1679 non-zero then the buffer is allocated that large. If zero, then
1680 the size is approximated using silc_mp_sizeinbase, which however
1683 * Created Global RNG API which is global RNG that application can
1684 initialize. After initializing, any routine anywhere in the
1685 code (including library) can use RNG without allocating a new
1686 RNG object. This was done to allow this sort of use of the
1687 RNG in code that has no chance to allocate RNG object. All
1688 applications currently allocate this and many routines in the
1689 library use this. Affected file lib/silccrypt/silcrng.[ch].
1691 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1692 it to use the Global RNG API.
1694 * Defined Authentication Payload into protocol specification that
1695 is used during SILC session to authenticate entities. It is
1696 used for example by client to authenticate itself to the server
1697 to obtain server operator privileges.
1699 Implemented this payload into the lib/silccore/silcauth.[ch].
1700 Implemented also routines for public key based authentication
1701 as the new protocol specification dictates.
1703 Moved definitions of different authentication methods from
1704 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1706 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1707 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1708 silc_pkcs_verify_with_hash functions into the file
1709 lib/silccrypt/silcpkcs.[ch].
1711 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * The client entry's userinfo pointer must be always valid.
1714 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1715 will fail since it requires the userinfo. Now, the userinfo
1716 is allocated as "" if actual userinfo does not exist. Actually,
1717 it must exist and it is totally Ok to drop client connections
1718 that does not announce the userinfo. However, we will make
1719 this workaround for now.
1721 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1722 to return the remote port by socket.
1724 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1727 SILC_SERVER_PENDING_EXEC and added an new macro
1728 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1729 data or when error occurs while processing the pending command.
1731 Added new argument `destructor' into silc_server_command_pending
1732 and to the SilcServerCommandPending object. This destructor is
1733 now called after calling the pending callback or if error occurs
1734 immediately. If error occurs the actual pending callback won't
1735 be called at all - only the destructor. The destructor may be
1736 NULL if destructor is not needed.
1738 All this applies for client library code as well. Similar
1739 changes were made there as well for the pending commands.
1741 In the client, the application must now allocate the
1742 SilcClientCommandContext with the silc_client_command_alloc
1745 * Added reference counter to the SilcServerCommandContext. Added
1746 function silc_server_command_alloc and silc_server_command_dup
1749 Same type of functions added to the client library for the same
1752 * Removed the cmd_ident from IDListData away since it is now
1753 global for all connections. It is the command identifier used
1754 in command sending and with pending commands. The affected file
1757 * Added reference counter to the SilcSocketConnection objecet to
1758 indicate the usage count of the object. The object won't be
1759 freed untill the reference counter hits zero. Currently only
1760 server uses this, and client ignores it. The client must be
1761 set to use this too later. The affected files are
1762 lib/silccore/silcsockconn.[ch]. Added also the function
1763 silc_socket_dup to increase the reference counter.
1765 This was mainly added because it is possible that the socket
1766 is removed underneath of pending command or other async
1767 operation. Now it won't be free'd and proper DISCONNECTING
1768 flags, etc. can be set to avoid sending data to connection that
1769 is not valid anymore.
1771 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1772 the connection. After that it sets SILC_SET_DISCONNECTED.
1773 It is, however, possible that the socket data is not still freed.
1774 The silc_server_packet_process now checks that data is not
1775 read or written to connection that is DISCONNECTED. The socket
1776 get's freed when the reference counter hits zero.
1778 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Changed the client operation API: channel_message operation's
1781 `sender' is now the client entry of the sender, not the nickname
1782 and the `channel' is the channel entry, not the channel name.
1784 In the private_message operation the `sender' is now also the
1785 client entry of the sender not the nickname.
1787 Affected file is lib/silcclient/ops.h and all applications
1788 using the client operations.
1790 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Moved the calling of ops->connect() from connect_to_server_final
1793 into receive_new_id functin since that is the point when the
1794 client is actually allowed to send traffic to network. The
1795 affected file is lib/silcclient/client.c.
1797 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1800 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1801 (if needs broadcasting) instead of broadcasting the packets one
1802 by one which would make a burst in the network traffic.
1804 * Added `broadcast' argument to the functions in silcd/server.[ch]
1805 silc_server_create_new_channel[_with_id] to indicate whether
1806 to send New Channel packet to primary router.
1808 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Added new function into the silcd/server.[ch] files:
1811 silc_server_create_new_channel_with_id to create new channel with
1812 already existing Channel ID.
1814 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1815 lib/silccore/silcpacket.h. This packet is used t send list of
1816 Set Mode payloads inside one packet. Server uses this to set
1817 the modes for the channels and clients on those channels, that it
1818 announced to the router when it connected to it. The protocol
1819 specification has been updated accordingly.
1821 * The silc_server_new_channel did not handle the packet coming
1822 from normal server as it normally does not send that. However,
1823 when it announces its channels it does send it. Implemented
1824 the support for that.
1826 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1827 into the file lib/silccore/id.h.
1829 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Fixed memory leaks in the functions silc_idlist_del_client,
1832 silc_idlist_del_channel and silc_idlist_del_server in the file
1833 silcd/idlist.c. All of those leaked like a sieve.
1835 * Fixed some small memory leaks in the client's function
1836 silc_client_notify_by_server.
1838 * Added functions into silcd/server.c: silc_server_announce_clients,
1839 silc_server_announce_channels and silc_server_announce_server.
1840 These functions are used by normal and router server to announce
1841 to its primary router about clients, channels and servers (when
1842 router) that we own. This is done after we've connected to the
1845 These functions effectively implements the following packet types:
1846 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1847 and SILC_PACKET_NEW_ID_LIST.
1849 * Added new functions into the silcd/packet_receive.[ch]:
1850 silc_server_new_id_list, silc_server_new_channel_list and
1851 silc_server_new_channel_user_list to handle the incoming
1852 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1854 * Added support of changing Channel ID in the function
1855 silc_server_replace_id. If the server that announces a channel
1856 to the router already exists in the router (with same name but
1857 with different Channel ID), router is responsible to send
1858 Replace ID packet to the server and force the server to change
1859 the Channel ID to the one router has.
1861 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1862 client that the Channel ID has been changed by the router. The
1863 normal server sends this to the client. Client must start using
1864 the new Channel ID as the channel's ID.
1866 Implemented handling of this new type into lib/silcclient/client.c
1867 into the function silc_client_notify_by_server.
1869 * Added new function silc_idlist_replace_channel_id into the files
1870 silcd/idlist.[ch] to replace the Channel ID.
1872 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Call silc_server_command_identify_check always when processing
1875 the IDENTIFY command in silcd/command.c
1877 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1880 send keepalive packets. The packet can be sent by clients,
1881 servers and routers.
1883 Added function silc_socket_set_heartbeat into the file
1884 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1885 If not set, the heartbeat is not performed. The actual
1886 heartbeat is implemented in the low level socket connection
1887 library. However, application is responsible of actually
1890 Added silc_server_send_heartbeat to send the actual heartbeat
1891 packet into silcd/packet_send.[ch]. Server now performs
1892 keepalive with all connections.
1894 * Added silc_task_get_first function into lib/silcutil/silctask.c
1895 to return the timeout task with shortest timeout. There was a bug
1896 in task unregistration that caused problems. TODO has been
1897 updated to include that task system must be rewritten.
1899 * The client library will now resolve the client information when
1900 receiving JOIN notify from server for client that we know but
1901 have incomplete information.
1903 * Rewrote parts of silc_server_remove_from_channels and
1904 silc_server_remove_from_one_channel as they did not remove the
1905 channel in some circumstances even though they should've.
1907 * Encryption problem encountered in server:
1909 The LEAVE command used to send the Channel Key packet to the
1910 router immediately after generating it. However, the code
1911 had earlier sent Remove Channel user packet but not immediately,
1912 ie. it was put to queue. The order of packets in the router
1913 was that Channel Key packet was first and Remove Channel User
1914 packet was second, even though they were encrypted in the
1915 reverse order. For this reason, MAC check failed. Now, this
1916 is fixed by not sending the Channel Key packet immediately but
1917 putting it to queue. However, this is more fundamental problem:
1918 packets that are in queue should actually not be encrypted
1919 because packets that are sent immediately gets encrypted
1920 actually with wrong IV (and thus MAC check fails). So, packets
1921 that are in queue should be encrypted when they are sent to
1922 the wire and not when they put to the queue.
1924 However, the problem is that the current system has not been
1925 designed to work that way. Instead, the packet is encrypted
1926 as soon as possible and left to the queue. The queue is then
1927 just purged into wire. There won't be any fixes for this
1928 any time soon. So, the current semantic for packet sending
1931 o If you send packet to remote host and do not force the send
1932 (the packet will be in queue) then all subsequent packets to the
1933 same remote host must also be put to the queue. Only after the
1934 queue has been purged is it safe again to force the packet
1937 o If you send all packets immediately then it safe to send
1938 any of subsequent packets through the queue, however, after
1939 the first packet is put to queue then any subsequent packets
1940 must also be put to the queue.
1942 Follow these rules and everything works fine.
1944 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Added new function silc_server_remove_clients_by_server to
1947 remove all client entries from ID list when the server connection
1948 is lost. In this case it is also important to invalidate all
1949 client entires as they hold the invalid server entry. This
1950 fixes fatal bug when server has lost connection and will reconnect
1953 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Made some sanity checks to silc_server_daemonise like to check
1956 whether the requested user and group actually exists.
1958 * Added sanity check to SKE's silc_ske_responder_finish to check
1959 that the public and private key actually is valid.
1961 * Invalidate the client's nickname when receiving Replace ID
1962 packet and the Client ID is being replaced. This means that the
1963 server will query the nickname if someone needs it (client)
1966 * Sort the ID Cache in client library when the ID Cache data
1967 has changed (needs sorting).
1969 * Do not allow for SILC client to create several connections to
1970 several servers. The client does not support windows right now
1971 and generating multiple connections causes weird behaviour.
1973 Irssi-silc client does support windows and can handle several
1974 connections without problems, see: www.irssi.org and SILC plugin.
1976 * Fixed some places where client was added to the IDList. The
1977 rule of thumb is following (in order to get everything right):
1978 If the client is directly connected local client then the
1979 `connection' argument must be set and `router' argument must be
1980 NULL to silc_idlist_add_client function. If the client is not
1981 directly connected client then the `router' argument must
1982 bet set and the `connection' argument must be NULL to the
1983 silc_idlist_add_client function.
1985 * The funtion silc_server_packet_send_local_channel actually did
1986 not check whether the client was locally connected or not. It
1987 does that now. Fixed a bug related to LEAVE command.
1989 * Fixed Remove Channel User payload parsing bug in server's
1990 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1992 * The server's silc_server_save_channel_key now checks also the
1993 global ID list for the channel as it might not be in the local
1994 list. Fixed a bug related to LEAVE command.
1996 * Is this the end of the [<unknown>] buglet that has been lurking
1997 around for a long time? A little for loop fix in server's
1998 silc_server_command_whois_parse that is used by both IDENTIFY
1999 and WHOIS command. At least, this was a clear bug and a cause
2000 of one type of [<unknown>] buglet.
2002 * WHOIS and IDENTIFY commands call the function
2003 silc_server_command_[whois/identify]_check function even if
2004 we are not router server.
2006 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Added --with-gmp configuration option. If set the GMP
2009 is always compiled in the SILC source tree. If not set then
2010 it is checked whether the system has the GMP3 installed. If
2011 it has then the GMP won't be compiled (the system's headers
2012 and library is used), if it doesn't have it then the GMP is
2013 compiled in the SILC source tree.
2015 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Changed RSA private exponent generation to what PKCS #1
2018 suggests. We try to find the smallest possible d by doing
2019 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2020 not security fix but optimization.
2022 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Added new config entry [Identity] to fork the server and run
2025 it as specific user and group. A patch from Bostik.
2027 * Imported Dotconf configuration library into lib/dotconf.
2028 This will be used to create the SILC configuration files later.
2029 It will appear in the distsribution after this commit.
2031 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * A big code auditing weekend happening. Auditing code for
2034 obvious mistakes, bugs and errors. Also, removing any code
2037 Removed files for being obsolete:
2039 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2040 inline in the file lib/silcutil/silcbuffer.h)
2042 o lib/silcutil/silcbufutil.c (the header has inline versions)
2044 Changed code to fix possible error conditions:
2046 o The buffer formatting routines now check that the destination
2047 buffer really has enough space to add the data. This applies for
2048 both buffer formatting and unformatting
2049 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2050 unformatting was changed to accomodate following rules:
2051 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2052 sent to the function while XXX_*STRING will not allocate or copy
2053 the data into the buffer. Instead it sets the pointer from the
2054 buffer into the pointer sent as argument (XXX_*STRING used to
2055 require that the pointer must be allocated already). This change
2056 makes this whole thing a bit more consistent and more optimized
2057 (note that the data returned in the unformatting with XXX_*STRING
2058 must not be freed now). The routines return now -1 on error.
2060 o Tried to find all code that use buffer_format and buffer_unformat
2061 and added return value checking to prevent formatting and
2062 especially unformatting errors and possible subsequent fatal
2065 o Changed ske->x and ske->KEY to mallocated pointers in
2066 lib/silcske/silcske.h. Fixed possible data and memory leak.
2068 o Added return value checking to all *_parse* functions. Fixed
2069 many memory leaks as well.
2071 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2072 so that buffer overflows would not happen. All code now also
2073 checks the return value as it can fail.
2075 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Added reconnection support to server if the normal server looses
2078 its connection to the router (for example if router is rebooted).
2079 The server performs normal reconnection strategy implemented
2080 to the server. Affected file silcd/server.c.
2082 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added new packet type SILC_PACKET_SET_MODE that is used to
2085 distribute the information about changed modes (for clients,
2086 channels and clients channel modes) to all routers in the
2087 network. Updated the protocol specification accordingly.
2089 Added functions into silcd/packet_send.c and
2090 silcd/packet_receive.c: silc_server_send_set_mode,
2091 silc_server_set_mode.
2093 Added new files silcmode.[ch] into lib/silccore that implements
2094 the encoding and decoding of Set Mode Payload. Added new type
2095 SilcSetModePayload. Moved the definitions of different modes
2096 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2098 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Oops, a little mistake in server's connection authentication
2101 protocol. The protocol is not ended with FAILURE but with
2102 SUCCESS if the authentication is Ok. :) Affected file is
2105 * Implemented NICK_CHANGE notify handling in server in the file
2106 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2107 the local clients on the channel. After the changing nickname
2108 in router environment snhould work and the [<unknown>] nickname
2109 should appear no more.
2111 The silc_server_replace_id function that receives the Replace ID
2112 payload now sends the NICK_CHANGE notify type also in the file
2113 silcd/packet_receive.c
2115 * Changed WHOIS and IDENTIFY command to support the maximum amount
2116 of arguments defined in protocol specs (3328 arguments). This
2117 fixed a bug that caused problems when there were more than three
2120 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Added extra parameter, command identifier, to the
2123 silc_client_send_command so that explicit command identifier
2126 Changed that ID list routines uses specific command identifier
2127 when sending WHOIS/IDENTIFY requests to the server so that they
2128 can be identified when the reply comes back.
2130 Affected files lib/silcclient/command.[ch],
2131 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2133 * Added `sender' argument to silc_server_packet_send_to_channel
2134 to indicaet the sender who originally sent the packet to us
2135 that we are now re-sending. Ignored if NULL. Affected file
2136 silcd/packet_send.[ch].
2138 * Added some server statistics support in silcd/server_internal.h
2139 SilcServerStatistics structure and around the server code. Also
2140 send some nice statistics information when client is connecting
2143 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Fixed channel ID decoding in server's JOIN command reply in
2146 silcd/command_reply.c
2148 * Fixed braodcasting of replace ID payload to not to send it if
2149 we are standalone server in silcd/packet_receive.c.
2151 * Fixed all channel message sending routines to not to send
2152 packets to clients that has router set, since they are routed
2153 separately in the same function earlier. Affects file
2154 silcd/packet_send.c and all channel packet sending functions.
2156 * In USERS reply, res_argv[i] are not allocated, the table
2157 is allocated. Thus changed that free the table, not its
2160 * In server's whois_check and identify_check if the client is
2161 locally connected do not send any WHOIS commands - they are not
2164 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Fixed some minor bugs in client when sending WHOIS command. The
2167 arguments was in wrong order.
2169 * Removed statis function add_to_channel from server in
2170 silcd/command.c that was previously used with the joining but
2173 * Tested USERS command in router environment successfully with two
2174 routers, two servers and two clients.
2176 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Reorganized the USERS command and command reply in client library
2179 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2180 When the command is given by user we register a pending command
2181 callback that will reprocess the command after the reply has been
2182 received from the server. When reprocessing the packet we then
2183 display the information. Thus, the USERS information is displayed
2184 now in the command callback instead of in the command reply
2185 callback. The processing of the command is same as previously
2186 when server has sent the command reply in the JOINing process.
2188 * Added to USERS command in silcd/command_reply.c to join the client,
2189 we didn't use to know about, to the channel after we've created
2190 a client entry for it. Also, for clienet we did know already still
2191 check whether it is on the channel or not and add it if not.
2193 * Removed silc_server_command_join_notify as the function and its
2196 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Changed the client's pending command handling to the same as the
2199 server's pending command handling. It is also now possible to
2200 execute command reply functions from other command reply
2201 function as the function callbacks for commands and command
2202 replies are one and same. The pending commands are not static
2203 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2204 in client connection context. Thus, pending commands are server
2205 connection specific as it is convenient.
2207 Changed the function silc_client_command_pending and
2208 silc_client_command_pending_del and added new function
2209 silc_client_command_pending_check. Removed the
2210 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2213 * Added cmd_ident, current command identifier, to the client
2214 connection context in lib/silcclient/client.h to keep track on
2215 command identifiers used in command sending. Client's command reply
2216 function handling now supports the mandatory command identifiers.
2218 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2219 funtions in client to fully support pending command callbacks.
2221 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2222 as one of the arguments to the application in the command reply
2225 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2226 before first releasing SILC but came back. Now it is removed again
2227 and should come back nomore. The FORWARDED flag was used only
2228 by the JOINing procedure by forwarding the command packet to router.
2229 Now, the JOINing procedure has been changed to more generic (due
2230 to various router environment issues) and FORWARDED is not needed
2231 anymore for anything. The protocol specification is yet to be
2234 Now, removed silc_server_packet_forward from server and the flag
2235 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2237 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Renamed NAMES command to USERS command. The NAMES was named that
2240 due to historical reasons. Now it is renamed. Also, rewrote
2241 parts of the USERS command. The nickname list is not sent anymore
2242 by the server. Only Client ID and mode lists are sent in the USERS
2243 command. Changed this also to the protocol specification.
2245 The client now resolves the names and stuff after it receives
2246 the USERS list from the server when joining to the channel.
2248 * WHOIS and IDENTIFY commands has been changed to support multiple
2249 Client ID's per command. One can now search for multiple users
2250 in the network by sending only one WHOIS or IDENTIFY command.
2251 Changed the code and the protocol specifications.
2253 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2254 uses silc_server_command_whois_parse to parse the request. */
2256 * If normal server, do not parse the WHOIS and IDENTIFY requests
2257 before sending it to the router. Saves some time.
2259 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Fixed JOIN command on client library. Wrong number of arguments
2262 used to crash the client.
2264 * Added silc_server_channel_has_global function to check whether
2265 channel has global users or not.
2267 * Added silc_server_channel_has_local function to check whether channel
2268 has locally connected clients on the channel.
2270 * The silc_server_remove_from_one_channel now checks whether the
2271 channel has global users or not after given client was removed from
2272 the channel. It also checks whether the channel has local clients
2273 on the channel anymore. If it does not have then the channel entry
2274 is removed as it is not needed anymore.
2276 * The silc_server_notify now checks on JOIN notify whether the joining
2277 client is one of locally connected or global. If it is global then
2278 the channel has now global users on the channel and that is marked
2279 to the channel entry. Also, it now saves the global client to
2280 global list who is joining and JOINs it to the channel. This is
2281 for normal server, that is.
2283 Changed silc_server_send_notify_on_channel,
2284 silc_server_packet_relay_to_channel and
2285 silc_server_packet_send_to_channel check if we are normal server
2286 and client has router set (ie. global client) do not send the
2287 message to that client, as it is already routed to our router.
2289 * Implemented LEAVE notify type handling in silc_server_notify
2292 * Tested LEAVE command in router environment successfully. Tested
2293 with two routers, two servers and two clients.
2297 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2299 * Implemented SIGNOFF notify type handling in silc_server_notify
2302 * silc_server_remove_id now removes the client entry from all channels
2303 it has joined and thusly sends SIGNOFF notify type.
2305 * Rewrote the NAMES list generation in server by removing two excess
2306 loops. The lists are created now inside one loop.
2308 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * silc_server_remove_channel_user checks now also global list
2311 for channel and client.
2313 * silc_server_new_channel_user checks now both local and global
2314 list for channel and client. Fixed a bug in client id decoding.
2315 Used to decode wrong buffer.
2317 * silc_server_channel_message checks now both local and global
2318 list for channel entry.
2320 * Tested channel joining (hence JOIN) in router environment
2321 successfully. Tested with two routers, two servers and two
2324 * Tested channel message sending in router environment successfully.
2326 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Added silc_server_save_channel_key into server.[ch] to save the
2329 received channel key in Channel Key payload processing. It is
2330 also used in JOIN command reply handling.
2332 Equivalent function silc_client_save_channel_key added into
2333 client.[ch] into client library.
2335 * Changed JOIN command reply to send information whether the channel
2336 was created or not (is existing already) and the channel key
2337 payload. Changed protocol specs accordingly.
2339 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2340 the request was sent by ID and not by nickname. Crashed on
2343 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2346 now correctly save the received data.
2348 * silc_server_free_sock_user_data now notifies routers in the
2349 network about entities leaving the network.
2351 At the same time implemented functions silc_server_remove_id
2352 and silc_server_send_remove_id to receive and send REMOVE_ID
2353 packets. The packet is used to notify routers in the network
2354 about leaving entities. The ID removed will become invalid in
2357 * Added function silc_idlist_del_server into server. Removes and
2358 free's server entry from ID list.
2360 * silc_server_private_message function now checks, if we are router,
2361 that the destination ID really is valid ID, naturally.
2363 * In router when NEW_ID packet is received (for new client) the
2364 hash of the Client ID is saved in the ID Cache but the
2365 client->nickname is set to NULL, instead of putting the hash
2368 IDENTIFY command now also checks that client->nickname must be
2369 valid. If it is not if will request the data from the server who
2370 owns the client. Added new function
2371 silc_server_command_identify_check.
2373 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2374 to set the command to already allocated Command Payload.
2376 * Tested private message sending in router environment with two
2377 routers, two servers and two clients. Fixed minor bugs and now
2380 * Fixed segfault from client's NAMES command. Used to crash if
2383 * Forwarded packets must not be routed even if it is not destined
2384 to the receiver. Changed server code comply with this.
2386 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Added `require_reverse_mapping' boolean value to ServerParams
2389 structure. If TRUE (not default) the server will require that
2390 the connecting host has fully qualified domain name.
2392 If the reverse mapping is not required and hostname could not be
2393 found the IP address is used as hostname.
2395 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Implemented version string checking to both client and server.
2398 The check is incomplete currently due to the abnormal version
2399 strings used in development version of SILC.
2401 * Changed all command functions in server to use the new
2404 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Changed char *data to unsigned char *data in ID Cache system to
2407 support binary data as ID Cache data. Changed code to support
2408 binary data in lib/silccore/idcache.c.
2410 * Renamed silc_server_packet_relay_command_reply to
2411 silc_server_command_reply as it is normal packet receiving
2412 function. Rewrote the function to accept command replys for
2413 servers and not only for clients.
2415 * Mark remote router always as registered server if we are connecting
2416 to it. Otherwise, commands sent by the router to us are ignored.
2418 * All ID List find routines now returns the ID Cache Entry pointer
2419 as well if requested.
2421 * WHOIS command works now in router environment, tested with two
2422 routers, two servers and two clients.
2424 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2425 in router environment (as it is almost equivalent to WHOIS) but
2426 hasn't been tested thoroughly. Added new functions:
2428 silc_server_command_identify_parse
2429 silc_server_command_identify_send_reply
2430 silc_server_command_identify_from_client
2431 silc_server_command_identify_from_server
2433 * Disabled route cache adding because adding two different ID's with
2434 same IP replaces the old cache entry thus giving wrong route.
2435 The entry->router->connection is always the fastest route anyway
2436 so route cache may not be needed. Of course, new routes maybe
2437 established after receiving the ID when the entry->router->connection
2438 might not be anymore the most optimal.
2440 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Add route cache for received ID for fast routing.
2444 * Added silc_server_packet_route to route received packet on router
2445 that is not destined to us.
2447 * Renamed silc_server_get_route to silc_server_route_get.
2449 * Added id_string and id_string_len fields into SilcServer to
2450 include encoded ServerID for fast comparing without excess
2451 encoding of the ID's.
2453 * Cleaned up WHOIS command on server side. Added following static
2456 silc_server_command_whois_parse
2457 silc_server_command_whois_check
2458 silc_server_command_whois_send_reply
2459 silc_server_command_whois_from_client
2460 silc_server_command_whois_from_server
2462 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2463 arguments in command replies. All command functions should be
2464 updated to use this macro.
2466 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Minor typo fixes on command reply handling on server.
2470 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Added silc_server_command_add_to_channel internal routine to add
2473 the client to the channel after router has created the channel and
2474 sent command reply to the server.
2476 * Added generic silc_server_send_command to send any command from
2479 * Use static buffer with ID rendering instead of duplicating data.
2481 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Fixed a channel user mode bug when joining to a channel server gave
2484 everybody channel founder rights, oops.
2486 * We mark ourselves as the router of the incoming server connection
2487 if we are router ourselves. This way we can check in some packet
2488 sending functions whether it is locally connected server. For
2489 incoming router connections we put NULL.
2491 * For router sending packets locally means now always sending the
2492 packet cell wide; to local clients and local servers. For normal
2493 server sending packet locally means sending it to only local
2496 * Fixed the JOIN command to really work in router environment. If the
2497 channel is created it is always created by the router. Router is
2498 also responsible of making the initial joining to the channel,
2499 sending JOIN notify to the sending server and distributing
2500 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2501 does not exist server doesn't do anything else but forward the
2502 command to the router which performs everything.
2504 * Added silc_server_send_channel_key function to send the Channel Key
2507 * Added silc_server_create_channel_key to create new channel key. The
2508 channel key is now re-generated everytime someone joins or leaves
2509 a channel, as protocol dictates. Note: channel->key_len is the
2512 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2515 packet_receive.[ch] to separate packet sending and receiving
2516 routines. The server.[ch] now includes everything else including
2517 actual packet processing (writing and reading data) and other
2520 Renamed silc_server_private_message_send_internal to
2521 silc_server_send_private_message. The routine is still though
2522 used only to relay private messages as server does not send
2523 private messages itself.
2525 Renamed silc_server_new_channel to silc_server_create_new_channel
2526 and added new function sicl_server_new_channel that handles the
2527 incoming New Channel packet. Added also new sending function
2528 silc_server_send_new_channel to send New Channel Payload.
2530 * Added new function silc_server_notify to process incoming notify
2531 packet to the server/router. Server may then relay the notify
2532 to clients if needed.
2534 * Added new function silc_server_new_channel_user to process incoming
2535 New Channel User packet. Router will redistribute the packet and
2536 send JOIN notify to its local clients and locally connected servers
2537 if needed. Normal server will send JOIN notify to its local client
2538 on same channel when received this packet. Added also corresponding
2539 sending function silc_server_send_new_channel_user to sent the
2542 * Added boolean route argument to send_notif_to_channel and
2543 packet_send_to_channel functions to attempt to route the packet
2544 if it is TRUE and send only locally if it is FALSE.
2546 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * silc_server_replace_id now broadcasts the received replace ID
2549 packet if it is not broadcast packet already. The router must
2550 broadcast to inform other routers about changed ID.
2552 * Added backpointer to server's router into SilcServer context in
2553 silcd/server_internal.h.
2555 * Fixed silc_server_packet_broadcast to send correct broadcast
2558 * The channel key is now distributed to the local client as soon
2559 as it is received from the router (in router environment) so that
2560 no other packet may be sent for the channel until client has
2563 * silc_server_remove_channel_user now broadcasts the received
2564 Remove Channel User packet if it is not broadcast packet already.
2565 The router must broadcast to inform other routers about removed
2568 * Added users field into SilcPacketContext that is a reference count
2569 of the context. One can increase the reference count by calling
2570 silc_packet_context_dup which is now changed to just increase the
2571 reference count instead of duplicating the data. The reference
2572 count is decresed by calling silc_packet_context_free that will
2573 free the data after the reference count hits zero.
2575 For now on the packet context and everything allocated into it
2576 (including the raw packet from network) must be freed by calling
2577 the new silc_packet_context_free function. Added also new function
2578 silc_packet_context_alloc that must be used now to allocate the
2579 context. This also means that if a routine is asynchronous from
2580 silc_[client/server]_packet_parse_type the packet context must
2581 be duplicated by calling silc_packet_context_dup. Otherwise it
2582 gets free'd after silc_[client/server]_packet_parse_type returns.
2583 Also, one must remember that if packet is duplicated then its
2584 reference count must be decresed by calling the free function as
2585 many times as it was duplicated.
2587 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2588 from both client and server.
2590 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Made joining to a channel working in router environment.
2594 * Cleaned up JOIN command on server side and create function
2595 silc_server_command_join_channel internal routine to make the
2598 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2600 * Changed silc_command_pending list to SilcDList. Also, added
2601 `ident' field to SilcServerCommandPending structure to identify
2602 the reply and to call correct callback.
2604 Added silc_server_command_pending_check function to replace the
2605 corresnponding macro. The silc_command_pending list is not
2608 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2609 to set identifier to previously allocated Command Payload. It
2610 is used to set identifier for command when resending Command
2613 * Added silc_command_payload_encode_payload to encode Command
2614 Payload buffer from SilcCommandPayload structure.
2616 * Added silc_argument_payload_encode_payload to encode Argument
2617 payload buffer from SilcArgumentPayload structure.
2619 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Changed WHOIS command to support router connection on server side.
2622 The whois request is always sent to router unless the server is
2623 standalone server. After server has received the reply from the
2624 router will it send the reply to the client.
2626 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2627 broadcast received broadcast packet. The function is used only
2628 by router. The broadcast packet is always sent to the router's
2631 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2632 render given ID to printable string, for log files for example.
2634 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Made basic router to router connections working. At least they
2637 can now connect to each other but nothing really works the way
2638 they are supposed - yet.
2640 * Added new initiator token to RouterConnection configuration
2641 file in silcd/serverconfig.[ch]. It is used to tell whether we
2642 are the initiator to the remote router or whether we'll expect
2643 the other end to connect.
2645 * Moved registering of listener task to silc_server_init, hence
2646 the server starts listenning as soon as it is run, even if it
2647 does not have connections to other routers. Let's see how well
2650 * Changed default connection retry timeouts for more suitable in
2653 * Removed cipher and such arguments from silc_idlist_add_client
2654 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2655 Added new function silc_idlist_add_data to add the keys and stuff
2658 * Added SilcIDListData structure and added it to SilcClientEntry
2659 and SilcServerEntry as their first field in the structure. This
2660 way we can explicitly cast the ID entries to the SilcIDListData
2661 structure and get common data for the entries. In past, we had
2662 to first check what type of connection it is and then cast it to
2663 correct ID entry type. Now, we can directly cast the opaque
2664 pointer to the SilcIDListData (no matter what ID entry it actually
2665 is) and get the data needed.
2667 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2670 in some circumstances even if threre were timeout tasks, though not
2671 IO tasks, but tasks anyway. Now fixed.
2673 * Defined SilcServerConnection structure to hold connection specific
2674 stuff about directly connected servers and routers. The definition
2675 is currently in silcd/server_internal.h. I thought about having
2676 a bit more important role fro this struct but for now it is used
2677 only when connecting to other server (or router actually).
2679 * Added connecting retry support in server when connecting to
2680 router(s). The retry feature implement exponential backoff
2681 algorithm. Also, added SilcServerParams structure to hold default
2682 parameters for server. For now, it include these retry settings
2683 and are hard coded. After server is moded to be as Silc Server
2684 Library this structure will be more important.
2686 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Changed client librarys channel->clients table to SilcList and
2689 changed code accordingly.
2691 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Changed client's channel table to SilcList and changed code
2694 accordingly. Also changed SilcChannelClientEntry to include back-
2695 pointer to the channel so that client entry can use that structure
2696 as list as well and we have fast cross-reference to the channel.
2697 This change dramatically decreased the complexity of channel
2698 handling with client entry and vice versa (removed one extra
2699 loop when searching for channel entry from many functions).
2701 * Changed server->sim from table to SilcDList and changed code
2704 * NAMES command can now be used from user interface. It will show
2705 the user list on the channel, neatly.
2707 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2708 Code now saves realname of the user if it becomes available.
2710 * Renamed configure.in to configure.in.pre and made ./prepare
2711 script to automatically add correct version string to
2712 configure.in which it creates from configure.in.pre.
2714 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * NAMES command reply now shows users mode with the nickname when
2719 * Moved silc_client_ch[u]mode[_char] functions from
2720 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2721 place sucks, they are utility functions and should be in some
2724 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2726 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2729 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Added TRQ (efficient deque and list library) into lib/trq. This is
2734 a very good list library that is currently used in the SILC. Defined
2735 SilcList API over the library because I didn't like the API very
2736 much. See lib/trq/silclist.h for the API and examples of how to
2737 use the API. Fixed various places in the code to use the new
2738 SilcList API. The SilcList is meant for lists that has a structure
2739 already defined as a list. It is not suitable to add just some
2740 context to the list (in TRQ, the context is the list actually).
2742 So, I defined SilcDList that can be used for the purpose where
2743 predefined list structure does not exit. This can be used as
2744 such list. Now some context just can be added to the SilcDList.
2745 Currently this list is not used in the SILC just yet, though there
2746 are a lot places where this can replace dynamically allocated
2747 tables and I will fix these places, later, to use SilcDList.
2748 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2749 and use TRQ internally).
2751 Also fixed some annoying warning messages that the original TRQ
2752 code generated. Also minor changes to TRQ's Makefile.in.
2754 * Added support for querying by Client ID to both WHOIS and
2755 IDENTIFY commands into server, as required by the protocol.
2757 * Removed method function pointers from SilcBuffer structure. They
2758 weren't used to anything and just increased the context size for
2759 no good reason. This change also made silc_buffer_alloc and
2760 silc_buffer_free functions inline functions.
2762 * Disabled command flooding detection support until it's fixed so
2763 that it accepts commands in but does not execute them more than once
2766 * Added silc_net_localhost(), to return local hostname, into
2767 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2768 that must be initialized before calling silc_client_init.
2770 * Added new function: silc_server_send_notify_on_channels to send
2771 notify messages to all channels client has joined. It is assured
2772 that the message is sent only once per client.
2774 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2775 lib/silcutil/silcutil.[ch] as silc_format function. The new
2776 function is generic and is used by server as well, not only by
2777 the logging routines.
2779 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2780 the provided version string was not acceptable. Added new function:
2781 silc_ske_check_version into lib/silcske/silcske.h. The function
2782 must be implemented by the application (client or server) and it
2783 does not reside in the SKE library. The function checks the version
2784 string remote end sent.
2786 * Added back pointers (to opaque context and to SilcSocketConnection)
2787 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2789 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2790 duplicate packet context structure.
2792 * Changed `notify' client operation to send same arguments as client
2793 receives from server except for ID's. ID's are mapped to correct
2794 ID entry and that is returned. Also, if channel entry is not sent
2795 by server but the notify is for channel the channel entry is sent
2796 to application (otherwise application doesn't know that it is for
2797 channel (library gets it from packet's Destination ID)).
2799 * Added silc_client_remove_from_channels into client library to
2800 remove a client from all channels it has joined to. Used when
2801 received SIGNOFF notify from server. Added also new function
2802 silc_client_replace_from_channels to replace old ID entry with
2803 new ID entry on all channels. Used when received NICK_CHANGE
2806 * Fixed ID Cache list handling in silc_idlist_get_client in
2807 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2808 to get (or query) client by ID.
2810 * Updated TODO list.
2812 * Added connection authentication status message defined by the
2813 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2814 support for these into the code in client and server side.
2816 * Added generic function silc_client_send_command to send any command
2817 with variable argument list. Application should use this function
2818 to send commands if the command functions provided by the library
2819 does not suite for the application's user interface needs.
2821 * Added new `failure' client operation. Application is notified about
2822 received failure packet if client is executing a protocol. In this
2823 case the protocol's execution has failed.
2825 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2826 is required by the protocol.
2828 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2829 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2832 * Added status flag to SilcSKE object to indicate realtime status
2833 of the SKE protocol.
2835 * Application receives now exactly same command reply arguments as
2836 the library receives from server. However, if ID is received the
2837 corresponding ID entry is returned to the application (eg. Client
2838 ID is mapped to correct SilcClientEntry entry and that is returned).
2839 Changed command_reply client operation due to this change.
2841 * Changed all ID's in commands and in command replys as ID Payloads.
2842 Change affected both client and server side codes.
2844 All ID's sent in SILC network (with execption of ID's in SILC
2845 Packet header) are sent in ID Payload to support variable length
2848 * Server now notifies nick changes and notifies all clients on
2849 the channels about the new nickname (about the new Client ID,
2852 * Implemented CMODE command to change channel modes. Supports all
2853 channel modes defined by the protocol specs except ban and invite
2854 lists. (Also, private channel key mode is supported but support for
2855 setting private channel key in client is missing, thus, this mode
2856 has no effect on client side (except that server requires that the
2857 client uses private channel key and normal channel traffic does not
2860 Also, invite mode works per se, but INVITE command does not work
2861 yet correctly, so you can set channel as invite only channel but
2862 inviting clients to the channel does not work (it is yet to be
2863 thought what's the best way to do it).
2865 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2866 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2867 Implemented CUMODE command to change user's mode on the channel.
2868 Supports all modes defined by the protocol specs.
2870 * Added NAMES command reply to return users modes on the channel.
2872 * Removed unnecessary and slow ciphers from lib/silccrypt.
2874 * Set SO_KEEPALIVE option to connection sockets by default.
2876 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2878 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2879 redefined the Notify Payload into protocol specs.
2881 * Added silc_id_payload_parse_id to get ID directly from raw
2884 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2887 accept searching by Client ID as well.
2889 * Added support for LEAVE and SIGNOFF notify types in client library.
2891 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2892 to parse ID Payload from raw data.
2894 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Added flags parameter into silc_ske_assemble_security_properties
2897 function in lib/silcske/silcske.[ch].
2899 * Changed notify client operation to fit better for notify messages
2900 sent by server. The notify payload received from server is now
2901 passed to the application (after parsing it to SilcNotifyPayload).
2902 It is application's responsibility to retrieve the arguments
2903 from the payload and show the message the way it wants. The message
2904 sent by server is implementation specific.
2906 * Changed public keys to comply with the protocol specification.
2907 Old public keys are not supported anymore and are not compatible.
2909 * Removed nickname from Channel Payload as the latest draft removed
2910 it. The client must resolve the nickname from the NAMES command
2911 reply received when it joined the channel.
2913 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2915 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Fixed some errors in protocol specification drafts.
2919 * Created lib/silccore/silcnotify.c to implement Notify Payload
2920 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2921 generic payloads described by protocol specifications. The file
2922 includes implementations for ID Payload and Argument Payload.
2924 * Changed Command Payload implementation to use the new Argument
2925 Payload. Changed command_xxxx_payload to command_payload_xxxx
2926 to comply with SILC coding conventions.
2928 * Added suppport for Argument Payload handling in Notify Payload
2929 implementation as protocol requires it. Added the new support
2930 into server and client lib as well.
2932 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Added support for multiple nicknames on same channel. [n] is
2935 added locally to the nickname if there are more than one same
2936 nicknames on the channel.
2938 * Server now sends all nicknames that matched WHOIS request.
2939 Client also shows the list received from server.
2941 * Added TOPIC command to client side. User can now set and show
2942 current topic on channel.
2944 * Added MOTD command to client and server. Also, server sends the
2945 motd when client connects to the server.
2947 * Changed version strings to comply ISO 8601.
2949 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Fixed protocol error handling in client library. It should now
2952 cope even if the SKE fails for some reason.
2954 * Made new protocol specification drafts for submitting to IETF.
2956 * Implemented TOPIC command to server in silcd/command.c.
2958 * Added two new notify types into lib/silccore/silcnotify.h:
2959 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2960 notify nickname change and topic setting/change on a channel.
2962 * API change of command_reply operation in client library. The
2963 application gets now the status type received from server as well.
2965 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2969 * Cras fixed and optimized the packet handling even further and
2970 it should work now. Minor change to the prototype of function
2971 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2973 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Added new function into lib/silcutil/silcschedule.[ch]:
2976 silc_schedule_with_fd to select() a specified fd. The function
2977 returns after timeout expires or data arrives or goes. The
2978 function is used by packet routines to wait that all data is
2979 received from network.
2981 * Fixed data reading from network in lib/silccore/silcpacket.c.
2982 The code now assures that all data is read from the fd and then
2983 continues packet processing. This was a bug fix since the code
2984 used to drop some data in some circumstances.
2986 * Added new function into lib/silcclient/client.[ch]:
2987 silc_client_start_key_exchange to start key exchange after
2988 connection has been established to server. The code internally
2989 now uses this funtion but its main purpose was to provide it
2990 for applications that perform their own connecting. After
2991 application has created a connection it merely calls this
2992 function to start the key exchange between client and server.
2993 The library takes care of everything else after that.
2995 Updated also lib/silcclient/README to explain the usage of
2998 * Do not send to application information that connection has
2999 been established. Application gets notified it by connect
3002 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3004 * Applied cras's patch to add silc_schedule_one function. The
3005 function runs scheduler once and returns.
3007 * Fixed the scheduler after cras messed it up. The timeout
3008 handling works now as it's supposed to work.
3010 * Added into lib/silccore/ silcnotify.h to include notify
3011 message types support. Changed silc_server_send_notify*
3012 functions, in server.[ch], to support those new notify types.
3013 Added the support for the notify types into client library,
3014 as well. Added new notify client operation into ops.h in
3017 * Changed silc_server_packet_send_to_channel to send normal
3018 packets instead of just channel message packets. The function
3019 is now used to send the notify packets to channels. It is not
3020 used to send channel message packets anymore, as server never
3023 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3024 va_arg()s as it seems to require it nowadays. I guess, if SILC
3025 is compiled with older va_arg() the new code should work anyway.
3027 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Splitted core library. Core library (lib/silccore) includes
3030 now only SILC protocol specific core (and common) components.
3031 Created new utility library (lib/silcutil) that includes more
3032 generic purpose stuff. The stuff for util library was taken
3033 from the old core library. This was minor and easy split.
3035 * Created SILC Client Library (lib/silcclient) that includes
3036 implementation of the SILC client without user interface. This
3037 was major move from silc/ directory. The code has been changed
3038 so that it is transparent towards the user interface. The
3039 silc/ directory includes now the same user interface as before
3040 and it uses the new client library. Read lib/silcclient/README.
3041 Basicly, the client library performs everything else related
3042 to SILC except user interface handling. Also, configuration
3043 files are considered to be part of user interface and library
3044 does not handle them.
3046 This change also changed a lot of structures, function naming etc.
3047 Most important change was that SilcClientWindow object was
3048 renamed to SilcClientConnection in the client library. Created
3049 also new file lib/silcclient/ops.h. Also added new files
3050 silc/local_command.[ch] and silc/client_ops.[ch].
3052 All these changes were made to make it easier for user interface
3053 designers to create what ever user interface for the SILC client
3056 It is also expected that the server will be moved to lib
3057 directory as well and SILC Server Library will be created;
3058 sometimes in the future.
3060 * Removed Local commands from lib/silccore/silccommand.h as
3061 they are application specific and new client library does not
3062 handle any of those anymore.
3064 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3065 old client implementation in silc/.
3067 * Added support for callback functions in SILC_LOG_* macros.
3068 Application can now set its own callbacks that will be called
3069 instead of using the default functions that will always print
3070 the debug messages to stderr (or stdout). Also, debugging can
3071 now be disabled by setting silc_debug to FALSE and re-enabled by
3072 setting it to TRUE. Note, that logging will still work even
3073 if debugging is disabled.
3075 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3076 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3077 silc_log_reset_debug_callbacks.
3079 * To enable debugging in silc client one must give now -d
3080 option on command line.
3082 * Changed silc_schedule_init to automatically allocate task queues
3083 if they are not allocated before calling it.
3085 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Added GMP 3.1 into math library.
3089 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3092 a channel in SILC network. The packet is used by servers and
3093 routers to notify other routers that user has left a channel.
3094 This little feature was missing until now. Added the feature
3095 to protocol specification as well.
3097 Added functions: silc_server_send_remove_channel_user and
3098 silc_server_remove_channel_user into server.[ch].
3100 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3101 lib/silccore/silcpacket.h. However, they are not implemented
3104 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Fixed joining to a channel and sending channel messages
3107 between server and router. The channel message sending should
3108 now work inside a cell.
3110 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Fixed the private message sending between server and router.
3113 The private message sending should now work inside a cell.
3115 * Added silc_server_replace_id into server.[ch] to replace
3116 existing ID in the SILC network.
3118 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3119 and silc_idlist_replace_server_id into idlist.[ch] in server.
3121 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Fixed the server to server connections. Server can again now
3124 connect to router. Router to router connections probably does
3127 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Added dynamic protocol registering support. Now protocols can
3130 registered and unregistered on the fly. Patch by cras.
3132 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Added lib/contrib directory to hold routines that some platforms
3135 don't have but are needed by SILC.
3137 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3138 into lin/contrib to provide getopt() and getopt_long() for
3139 those who don't have it.
3141 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Added AWAY command to client. When away message is set and
3144 client receives a private message packet the client automatically
3145 replies to the sender with the away message.
3147 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3148 bug seemed to be the cause of recent problems when compiling
3151 * Added version detection support to SKE protocol specification
3152 and added the new changes to the SKE implementation as well.
3153 There were other minor changes in the SKE protocol as well.
3155 Many changes in lib/silcske/silcske.[ch] and in
3156 lib/silcske/payload.[ch].
3158 * Added ^U functionality, clear input line. Patch from cras.
3160 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Mainly small bugfixes on core library. Fixed some debugging
3163 logging and buffer overflow in silclog.c.
3165 * Updated config.sub and config.guess on the distribution tree.
3167 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Added command lagging support in server. Client may execute
3170 commands now only once in two seconds.
3172 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Optimized packet reception. MAC computation and checking is now
3175 also more optimized. A lot previously duplicated code is now
3176 used as generic by both client and server.
3178 * Fixed key pair generation in clientutil.c
3180 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Added into lib/silccore/silcbufutil.[ch] new function;
3183 silc_buffer_realloc.
3185 * Moved generic packet sending/encryption functions to
3186 lib/silccore/silcpacket.[ch] from client and server. Some
3187 rewriting of the functions.
3189 * Moved all generic packet reception/decryption functions to
3190 lib/silccore/silcpacket.[ch] from client and server. The
3191 packet processing is now much cleaner in both client and server.
3192 These were major changes in both client and server.
3194 * Created many common functions in server to do packet sending.
3195 Previously code were duplicated a lot, this has been removed
3198 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Rewrote major parts of the ID cache system. Don't know
3201 whether it is better now or not but at least the API is more
3204 * Major rewrite on ID cache stuff on client because of the ID
3205 cache API changes. Added idlist.c to client.
3207 * Also major rewrite on ID cache stuff on server as well.
3208 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3209 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3210 in hand, instead they are all put into the ID cache system now.
3211 All server_idlist_* routines uses ID cache now instead of
3212 traversing its own lists (those lists does not exist anymore).
3213 SilcIDList though still exists. Also, SilcXXXEntry's are
3216 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Finally made the SKE implementation compliant to the protocol
3219 specification. All mp integers are now binary encoded as
3220 opposed being HEX encoded.
3222 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3225 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3226 functions: silc_[encode/decode]_pem. Also added function
3227 silc_encode_pem_file to PEM encode with newlines ('\n') for
3230 * SILC public keys are now encoded either PEM or binary. Same
3231 option is for private keys as well. By default private keys
3232 are binary encoded and public keys PEM encoded. Silly HEX
3233 encoding were removed.
3235 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3236 function to create fingerprints.
3238 * Fixed a bug in SHA1; does not change the original data anymore.
3240 * Partly implemented INFO command on client and server side.
3241 Fixed CLEAR command. Changes to SERVER command; show current
3242 server(s) when giving command without arguments. Added
3243 VERSION command to client.
3245 * Added check to server that unregistered connections cannot
3246 execute commands (unless it is specificly allowed).
3248 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Fixed screen refresh.
3252 * Fixed channel joining bug from client. On some circumstances
3253 client tried to join to a channel it had already joined.
3255 * Added public key verification process into client's protocol.c.
3256 The client now verifies the public key from user and saves
3257 it into ~./silc/serverkeys/ directory.
3259 Added into: clientutil.[ch]: silc_client_verify_server_key.
3261 * Changed SKE protocol's silc_ske_initiator_finish function
3262 to accept callback function that verifies the received public
3263 key. Removed old silc_ske_verify_public_key function.
3265 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3268 silc_pkcs_private_key[_data]_set.
3270 * Made the password and public authentication more cleaner in
3271 server's protocol.c.
3273 * Removed historic and obsolete protocol `channel_auth' from
3274 both client and server.
3276 * Removed wrong way of sending command status messages from
3277 server to client in server's command.c. The old way violated
3278 protocol specification.
3280 Changes to silccore/silccommand.[ch]: removed
3281 silc_command_encode_status_payload -> not needed anymore,
3282 changed silc_command_encode_payload_va to accept extra
3283 argument on variable argument list. The argument type must
3284 now be provided to the function. Also, added new function:
3285 silc_command_encode_reply_payload_va which is same as
3286 normal command_encode_payload_va except command status type
3287 is provided as extra argument.
3289 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Added ~./silc directory handling. The directory includes the
3292 public and private keys for the client.
3294 Added silc_client_check_silc_dir, silc_client_create_identifier
3295 and silc_client_load_keys.
3297 * Implemented SILC protocol compliant public key. Added public
3298 and private key saving to and loading from files.
3300 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3301 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3302 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3303 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3304 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3306 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3307 silc_pkcs_load_[public/private]_key.
3309 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Added silc_server_get_route (route.[ch]) to get connection
3312 data for the fastest route for given ID.
3314 * Implemented INVITE command on client and server. The command
3315 were re-defined in the SILC Protocol Specification and the
3316 implementation now complies with the specification.
3318 * Implemented PING command on client and server.
3320 * Implemented NAMES command on client and server. The server side
3321 supports currently only normal server not router server yet.
3322 Some changes to NAMES definition in SILC protocol specification.
3324 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Implemented LEAVE command on client and server.
3328 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3329 again. This change was made to the protocol as well. Server
3330 should not violate the protocol specification anymore.
3332 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3335 was tested. SOCKS4 was not but should work anyway.
