1 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added `sender_entry' argument to the function
4 silc_server_packet_relay_to_channel so that we can check
5 whether some destination actually belongs to the same route
6 the sender belongs (ie, we must not resend the packet to the
7 sender). Affected file silcd/packet_send.[ch].
9 * Added `servername' field to the SilcClientEntry in the server
10 to hold the name of the server where client is from. Affected
11 file is silcd/idlist.h.
13 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Moved the channel message encrypting in the router betwen
16 router connections from silc_server_channel_message to the
17 silc_server_packet_relay_to_channel since we want to check
18 whether we have anybody channel before encrypting anything.
19 Affected files silcd/packet_[receive/send].c.
21 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
23 * Fixed the [AdminConnection] server config section to support
24 multiple entries. Affected file silcd/serverconfig.c.
26 * Added support into the server to check the validity of the
27 incoming connection before executing any KE or authentication
30 * The connection configuration is now saved to the KE and
31 connection auth protocol contexts and not fetched anymore in
32 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
34 * The local hosts listenning address and port is also resolved
35 now when starting the server. We want to have the socket object
36 to include the real address and port for the listener. Added
37 new function silc_net_check_local_by_sock into the files
38 lib/silcutil/silcnet.[ch].
40 * Fixed a broadcast bug in server -> do not broadcast if we
43 * Fixed a routing bug. Do not route broadcast packets ever.
44 Broadcast packets must be processed always and not routed since
45 they may be destined to some other host than yourself and thus
46 would get routed without no good reason. Affected file is
49 * Added function silc_server_config_is_primary_route to check
50 whether primary router connection has been configured (a router
51 configuration that we are initiating). If there is not, we
52 will assume that there is only two routers in the SILC network
53 and we will use the incoming router connection as our primary
54 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
56 * Changed the order of the broadcasting. Broadcast _after_ the
57 packet has been processed not before. Affected file is
60 * Fixed a [ClientConnection] parsing bug. The port was never
61 parsed correctly thus resulting to port 0. Affected file
64 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
65 argument and did not set the broadcast packet flag. Affected
66 file silcd/packet_send.c. Fixed same bug in the function
67 silc_server_send_notify as well.
69 * If we receive NEW_ID packet for our own ID in the server, ignore
72 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Removed the nickname from the Private Message Payload.
77 Updated the code and the protocol specs.
79 * Updated protocol specs for submitting to the IETF.
81 * Tweaked the Random Number Generator a bit. Affected file
82 lib/silccrypt/silcrng.c. Exported a new function
83 silc_rng_[global]_add_noise which can be used to add more
86 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * Do not parse packets with different timeout when protocol
89 is active -> may cause problem with rekey. Affected file
92 * When server receives signoff notify it must not create
93 new channel key if the client is on any channels since the
94 sender of the signoff notify will create it.
96 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Added printing of error messages during SKE protocol from the
99 failure packet sent by server during SKE. Affected file
102 * Removed the client's failure_callback handling with timeout
103 and handle it immediately when received.
105 * The SKE library returned wrong type in SUCCESS and FAILURE
106 packets. They must be 32 bit MSB not 16 bit MSB.
108 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Ok, rewrote the logic of the re-key and now it seems to work.
111 I tested it on high traffic with frequent re-keys without
112 problems. Added hmac_receive (and renamed hmac to hmac_send)
113 in SilcClientConnection in lib/silcclient/client.h and
114 in SilcIDListData in silcd/idlist.h. Also, removed the
115 SilcPacketParserContext's cipher and hmac fields as they are
116 not needed anymore and actually caused some problems when
117 the ciphers and hmac's changed underneath the packet parser.
119 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * If re-key protocol is active then process the incoming packets
122 synchronously since we must assure that icoming packets encrypted
123 with the old key is processed before the new keys is set to
124 use. This is true other packets than for REKEY packets.
125 Affected file silcd/server.c. The same was done to client library
126 as well, affected file lib/silcclient/client.c.
128 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Fixed bug in client and server to accept the force send if
131 the packet is send from silc_[server/client]_packet_process
132 function. Otherwise the packets are never delivered, oops.
134 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Disable force sending of packets when REKEY protocol is active.
137 We must assure that no packet is sent directly when rekey is
138 performed. All packets must be sent through packet queue.
139 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
140 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
141 function is silc_[server/client]_packet_send_real to check
144 * Replaced the SIM paths from example config files to
145 /usr/local/modules. Also, make install creates now
146 /usr/local/silc/logs directory to hold all the SILC server
149 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Made the configure.in.pre work on Solaris. Patch by salo.
153 * Made all ciphers compatible with non-x86 machines. Defined
154 CBC mode macros into lib/silccrypt/ciphers_def.h.
156 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Fixed the make install.
160 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * When MAC computation fails the silc_packet_decrypt returned 0
163 even though it was supposed to return -1. Fixed this. The
164 affected file is lib/silccore/silcpacket.c.
166 * Do not replace the config files in /etc/silc (in make install)
167 if they already exist. Affected file ./Makefile.am.
169 * Do not send re-key packets immediately but through packet queue.
170 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
172 * Changed silc_net_check_host_by_sock to return FALSE if the
173 IP/DNS could not be resolved. Though, it returns the IP address
174 now even if it could not resolve it (but returns also FALSE).
175 Affected file lib/silcutil/silcnet.[ch].
177 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Added silc_pkcs_decode_identifier to decode the public key's
180 identifier. Affected file lib/silccrypt/silpkcs.[ch].
181 Added also silc_pkcs_free_identifier. Added also new context
182 SilcPublicKeyIdentifier.
184 * Added -S option to the silc client. It is used to dump the
185 contents of the specified public key file.
187 * Changed the PKCS api to return the public key length when
188 setting the public key.
190 * Fixed a fatal bug in the public and private key file loading.
191 Affected file lib/silccrypt/silcpkcs.c.
193 * Execute the packet parsing for client with zero (0) timeout
194 if the protocol is active. Affected file silcd/server.c.
196 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Made the key generation options to the silcd program. Added
199 -C option, equivalent to client's option.
201 * Added new [ServerKeys] config section to the server. It
202 configures the server's public and private key.
204 * Defined generic Public Key Payload into the protocol
205 specification to send specific type of public keys and
208 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
209 public key or certificate.
211 * Implemented the GETKEY command to the server and to the
212 client library and on user interface.
214 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Made preliminary `make install' work.
218 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Added SilcServerRekey context into silcd/idlist.h.
222 * Added the PFS support as defined in the specification to the
223 SKE protocol. Affected files lib/silcske/*.c.
225 * Added `ske_group' field to the SilcServerRekey context to hold
226 the number of the SKE group that is used with PFS in re-key.
227 Affected file silcd/idlist.h.
229 * Added PFS re-key support to the server. Affected file is
232 * Added silc_protocol_cancel to cancel execution of the next
233 state of the protocol. Affected file is
234 lib/silccore/silcprotocol.[ch].
236 * Added the re-key support with and without PFS to the client
237 library. Re-key is performed once in an hour, by default.
239 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
240 Added silc_client_rekey_callback and silc_client_rekey_final.
241 Affected files are lib/silcclient/protocol.[ch] and
242 lib/silcclient/client.[ch].
244 * Removed the `hmac_key' and `hmac_key_len' fields from the
245 SilcClientConnection structure; not needed. Affected file is
246 lib/silcclient/client.h.
250 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Do not ask whether user wants to use the negotiated private key
253 for private messages, just use it. Affected file is
254 silc/local_command.c.
256 * Added `send_enc_key' and `enc_key_len' fields to the
257 SilcIDListData structure since they are needed in the re-key
258 phase. Affected file is silcd/idlist.[ch].
260 * Implemented the simple re-key protocol into the server.
261 Affected files silcd/server.c and silcd/protocol.[ch]. The
262 re-key will be performed once in an hour, by default.
264 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
265 Added silc_server_rekey, silc_server_rekey_callback and
266 silc_server_rekey_final.
268 * Removed Tunneled flag from the protocol. Updated the code
269 and the specifications.
271 * Adde `pfs' field to the SilcIDListData to indicate whether
272 the PFS is to be performed in the re-key. Affected file is
275 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
278 int64 of at least the xintXX size. If void * is less that 4
279 bytes uint32 * will be used. Defined bool as boolean.
281 * Changed _ALL_ unsigned long and unsigned int to uint32,
282 unsgined short to uint16 in the source tree.
284 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
285 not handle clients that has entry->data.registered == FALSE.
286 They are not in the network anymore. Affected file is
289 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Implemented the sending of the SERVER_SIGNOFF notify in the
292 server. Affected file is silcd/server.c.
294 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
295 Added also silc_notify_payload_encode_args into the
296 lib/silccore/silcnotify.[ch].
298 * Implemented ther SERVER_SIGNOFF notify handling in the server.
299 Affected file silcd/packet_receive.c.
301 * Implemented the SERVER_SIGNOFF notify handling in the client
302 library. Affected file lib/silcclient/client_notify.c. Also,
303 implemnted the printing of the SERVER_SIGNOFF info to the
304 application. Affected file silc/client_ops.c.
306 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
307 if the deleting was successful. Affected file silcd/idlist.[ch].
309 * Added support for public key authentication in the connection
310 authentication protocol in the client library. Affected file
311 lib/silcclient/protocol.c.
313 * Changed the server's silc_idlist_get_clients_by_* interface
314 to support already allocated array so that new entries may be
315 added to pre-allocated array. Affected file silcd/idlist.[ch].
316 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
319 * All command reply functions in the server now calls the
320 pending command callback even if error occured. This way the
321 error will be delivered to the client as well. Affected files
322 silcd/command.c and silcd/command_reply.c.
324 * Fixed INFO command to return local server's info if no server
325 was provided. Affected file lib/silcclient/command.c.
327 * Removed RESTART command for good. Updated the code and the
330 * Rewrote parts of the task system. It is a bit simpler now.
331 Removed unsued task priorities. The affected files are
332 lib/silcutil/silctask.[ch].
334 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Moved the USERS printing from the library to the application.
337 Affected files lib/silcclient/command.c and silc/client_ops.c.
339 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added channel key re-key support. The re-key is perfomed
344 only by the router and is done once in an hour. Added `rekey'
345 field to the SilcChannelEntry in the server. Affected files
346 silcd/server.c and silcd/idlist.h.
348 * Added silc_task_unregister_by_context into the file
349 lib/silcutil/silctask.[ch].
351 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Added SILC_UMODE_GONE mode to indicate when the client is not
354 present in the SILC network. Added also support to the local
355 command AWAY that will set this mode. Added support of showing
356 "xxx is gone" in WHOIS command. The USERS command shows the
359 * Fixed setting server and router operator privileges in the
360 server's UMODE command. Affected file silcd/command.c.
362 * Merged the SKE KE1 and KE2 payloads into one payload. The
363 new KE payload is equivalent to the old KE2 payload.
365 Cleaned up the SKE Start Payload parsing. It now uses the
366 simple buffer unformatting to do the parsing. A lot faster
369 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
370 to the SKE that is used to indicate whether both of the SKE
371 parties should perform authentication. By default only the
372 responder performs authentication. By setting this flag also
373 the initiator must do authentication. By default it is unset
374 since in normal SKE case, client to server connection, only
375 the responder should do authentication. When doing SKE between
376 two clients both should perform authentication. Updated the
377 code and the protocol specs.
379 * A little fix to IDENTIFY command in the server. Search the
380 client first by hash not nickname. Affected file is
383 * Fixed the silc_client_close_connection to support closing
384 the client to client connections wihtout deleting too much
385 data. Affected file lib/silcclient/client.c.
387 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
388 are received if protocol used to be active but is not anymore
389 the application would crash due to NULL pointer dereference.
390 Affected files silcd/server.c and lib/silcclient/client.c.
392 * Added `hash' field to the SilcClientConnection to include
393 the hash function negotiated in the SKE protocol.
395 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
396 to set the channel founder authentication data. A client can
397 claim the founder rights later by providing the authentication
398 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
399 This way the channel founder can regain the channel founder
400 privileges even it is left the channel. This works only on
401 local server and the client must be connected to the same
402 server to be able to regain the founder rights. Updated the
403 protocol specs accordingly.
405 Added support to the CMODE command in the client to set the
406 founder auth data. Read the README to see how to set it.
408 Added support to the CUMODE command to claim the founder
409 rights. Read the README to see how to do it.
411 Added support for the founder authentication to the Channel
412 Entry in the server. Affected file silcd/idlist.h.
414 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
415 server's CMODE command. Affected file silcd/command.c.
417 * Added the following new functions into lib/silccore/silcauth.[ch]:
418 silc_auth_get_method and silc_auth_get_data.
420 * The server now saves the remote hosts public key to the
421 SilcIDListData pointer. Affected file silcd/protocol.c.
423 * The normal server now does not remove the channel entry from
424 the cache if the founder authentication data is set. It used
425 to remove it if the founder was the last one on the channel on
426 the server and left the channel. The auth data is saved and
427 if the channel is re-joined later the old entry is used with
428 the old auth data. Affected files silcd/command_reply.c and
431 * Removed the `pkcs' field from the SilcIDListData structure
432 in the server; it is not used. Affected file silcd/idlist.h.
434 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Fixed packet processing on slow links. Partial packets were
437 never re-processed because the incoming data buffer was cleared
438 by the application. Application must not directly clear the
439 sock->inbuf, the packet processing routines handle it. Fixed
440 this in client library and in server.
442 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Fixed the WHOIS and IDENTIFY send reply function to really
445 check whether to send list or just one entry. Affected file
448 * Cleaned up the LEAVE command's channel key distribution. The
449 affected file silcd/command.c.
451 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
452 can enforce the channel mode as well. In that case the ID
453 includes the ID of the server. The code now enforces the
454 mode change if the router have different mode than the server.
456 * The notify client operation with CMODE_CHANGE notify can now
457 return NULL client_entry pointer if the CMODE was not changed
458 by client. Application must check for this.
460 * Added <Server ID> argument to INFO command to support server
461 info fetching by Server ID.
463 * Added silc_server_announce_get_channel_users to get assembled
464 packets of channel users of the specified channel. Affected
465 file silcd/server.[ch].
467 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
468 was freed underneath the ID Cache.
470 * Re-announce clients when the server received CHANNEL_CHANGE
471 notify from the router. Affected file silcd/packet_send.c.
473 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
476 crashed since it did not handle the fact that there is no cipher
477 called "3" and didn't check the error condition. Now fixed.
479 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
480 flag. It can be used to send message requests.
482 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Implemented the RESTART command in the client.
486 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
487 notice type messages. Added notice printing to the user
490 * The channel keys are not re-generated if the channel's mode
491 is PRIVKEY, ie private key on the channel exists. Affected
492 files silcd/server.c and silcd/command.c.
494 * Fixed a little bug in channel message delivery when channel
495 private keys are set in the server. Affected file is
498 * Changed the setting on channel->on_channel = TRUE from the
499 silc_client_save_channel_key to the JOIN command reply. The
500 key payload is not received if the private channel key is set.
501 Affected file lib/silcclient/command_reply.c and the
502 lib/silcclient/client_channel.c.
504 * When the CMODE_CHANGE notify is sent and the channel private
505 key mode is removed the channel key must be re-generated in
506 other cells as well. Added this support for the router in the
507 silcd/packet_receive.c.
509 * Added new local command NOTICE to send notice message on
510 channel. Affected file silc/local_command.[ch].
512 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Added new local command ME to the client. It is used to send
515 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
516 some action. Affected file silc/local_command.[ch].
518 * Changed channel_message and private_message client operations
519 to deliver the message flags to the application. Added also
520 the `flags' arguments to the silc_client_send_channel_message
521 and silc_client_send_private_message functions. Affected file
524 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Redefined the Private Message Payload to support private message
527 keys and to support the new private message flags. Updated
528 the protocol specs. Flags makes it possible to have for example
531 * Added new type SilcPrivateMessagePayload and defined an API
532 for it in the lib/silcclient/silcprivate.[ch].
534 * Tested private message private keys successfully. Tested the
535 private message key set, unset and list commands with the new
538 * Redefined the Channel Message Payload to include the channel
539 message flags (equal with private message flags) to support
540 for example CTCP style messages.
542 * Defined some of the message (for channel and private message)
543 flags. Updated the protocol specs and added the flags to the
544 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
546 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Added SilcKeyAgreementStatus type to the key agreement routines
549 to indicate the current status and error if one occured.
550 The status types are defined in the lib/silcclient/silcapi.h.
552 * Added new local command KEY that is used to set and unset private
553 keys for channels, set and unset private keys for private messages
554 with remote clients and to send key agreement requests and
555 negotiate the key agreement protocol with remote client. The
556 key agreement is supported only to negotiate private message keys,
557 it currently cannot be used to negotiate private keys for channels,
558 as it is not convenient for that purpose.
560 * Fixed a minor pending callback setting bug in the function
561 silc_client_get_client_by_id_resolve, now the function works.
562 Affected file lib/silcclient/idlist.c.
564 * Added function silc_net_get_local_port to get local bound
565 port by socket. Added to lib/silcutil/silcnet.[ch].
567 * Added `sockets' and `sockets_count' fields to the SilcClient
568 object. They hold the sockets of the listenning sockets in
569 the client. Listenning sockets may be for example the key
570 agreement server. Affected file lib/silcclient/client.[ch].
571 Added functions the silc_client_add_socket and the
572 silc_client_del_socket. They are exported to the application
575 * Added ~./silc/clientkeys to support other client's public keys.
577 * Renamed verify_server_key client operation to verify_public_key
578 and added one argument to indicate the type of the connection
579 (server, client etc.).
581 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added silc_server_connection_auth_request to handle the
584 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
585 silcd/packet_receive.[ch].
587 * Added silc_server_send_connection_auth_request into the
588 silcd/packet_send.c to send the connection auth request packet.
590 * Cleaned up the silcd/protocol.c a bit and fixed some memory
593 * Fixed the public key authentication in responder side in the
594 server. The `auth_data' pointer includes the SilcPublicKey
595 not the path to the public key. Affected file silcd/protocol.c.
597 * Implemented the public key authentication in the initiator side
598 in the server. Affected file silcd/protocol.c.
600 * Removed the [RedirectClient] config section from the server
601 configuration. Is not needed and I don't want to implement it.
603 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
605 * Cleaned up the CMODE command in the server. It now works
606 correctly and supports all the modes defined in the protocol.
607 Affected file is silcd/command.c.
609 * Added `hmac_name' field to the SilcChannelEntry in the server
610 to hold the default HMAC of the channel. It can be set when
611 creating the channel (with JOIN command). Affected files
614 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
615 type to indicate the change of the current cipher and hmac
616 on the channel. Client can safely ignore the <cipher> argument
617 (if it chooses to do so) since the CHANNEL_KEY packet will
618 force the channel key change anyway. The <hmac> argument is
619 important since the client is responsible of setting the new
620 HMAC and the hmac key into use.
622 * Fixed the CMODE command in the client library as well.
624 * Tested CMODE command in router environment successfully.
626 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Show the version of the remote client (or server) when connecting
629 to the server. It is logged to the log file. Affected file
632 * Fixed the KILLED notify handling in the client library. The
633 client must be removed from all channels when receiving the
636 Also, do not remove the client entry when giving the KILL
637 command but when the KILLED notify is received.
639 * Removed silc_idlist_find_client_by_nickname from the server.
640 Not needed anymore. Affected files silcd/idlist.[ch].
642 * Implemented the CHANNEL_CHANGE notify type handling to the
643 server. Affected file silcd/server.c.
647 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Added silc_server_send_notify_invite to send the INVITE
650 notify between routers.
652 * Implemented the INVITE command correctly to the server.
654 * Implemented the INVITE notify type handling in the server.
656 * Implemented the INVITE command to the client library and on the
659 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Added function silc_server_get_client_resolve to find the
662 client entry by ID from all ID lists and then resolve it
663 (using WHOIS) if it cannot be found. Affected file is
666 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Implemented the BAN command to the client library.
670 * The JOIN command in the server now checks the invite list
673 * Changed the silc_command_reply_payload_encode_va and the
674 silc_command_payload_encode_va to support that if argument is
675 NULL it ignores and checks the next argument. Affected file
676 lib/silccore/silccommand.c.
678 * Added silc_server_send_notify_ban to send the BAN notify
679 type between routers.
681 * Chaned the silc_notify_payload_encode to support that if
682 argument is NULL it ignores and checks the next argument.
683 Affected file lib/silccore/silcnotify.c.
685 * Tested ban lists in router environment successfully.
687 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Implemented BAN command to the server, in silcd/command.[ch].
691 * Removed the BAN and INVITE_LIST modes from the CMODE command
694 * Added function silc_string_match to regex match two strings.
695 Affected files lib/silcutil/silcutil.[ch].
697 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Redefined parts of the SilcChannelEntry in the server to support
700 the new ban and invite lists.
702 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Redefined the INVITE command. The same command can be used to
705 invite individuals to the channel but also to manage the invite
706 list of the channel (to add to and remove from the invite list).
707 Updated the protocol specs.
709 * Added new command SILC_COMMAND_BAN that can be used to manage
710 the ban list of the channel. Updated the protocol specs.
712 * Removed the channel modes: the SILC_CMODE_BAN and the
713 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
714 in the CMODE command. The equivalent features are now available
715 using INVITE and BAN commands. Updated the protocol specs.
717 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
718 in the network about change in the current ban list. The notify
719 type is not used by the client.
721 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
722 support the invite lists.
724 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Added new function silc_string_regexify that converts string
727 including wildcard characters into regex string that can
728 be used by the GNU regex library. Added into the file
729 lib/silcutil/silcutil.[ch].
731 Added silc_string_regex_combine to combine to regex strings
732 into one so that they can be used as one regex string by
733 the GNU regex library. Added into the file
734 lib/silcutil/silcutil.[ch].
736 Added silc_string_regex_match to match two strings. It returns
737 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
739 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Imported GNU regex to the soruce tree into lib/contrib.
742 Fixed some compiler warning from the regex.c.
744 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Fixed MOTD command in the server to work in router environment.
748 * Fixed the MOTD command in the client library to support
749 the server argument in the command.
751 * Added `nickname_len' argument to the silc_idlist_add_client
752 in the server, as the `nickname' argument may be binary data
755 * Added silc_idlist_get_channels to return all channels from
758 * Implemented LIST command to the server. Affected file is
761 * Implemented the LIST command to the client library and on the
764 * Added [<user count>] argument to the LIST command reply.
765 With private channels the user count is not shown.
767 * Updated TODO and README.
769 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * The client entry's data.registered must be TRUE even with
772 global client entry on global client list. The data.registered
773 is used to check whether the client is anymore in the network,
774 for example with WHOWAS command so it must be valid.
776 * Fixed the WHOWAS command in the server. It now actually works
777 in router environment. Added function into silcd/command_reply.c
778 silc_server_command_reply_whowas_save.
780 * Added silc_idlist_purge function to the silcd/idlist.c
781 to periodically purge the ID Cache.
783 * Fixed INFO command in the server. It works now in router
784 environment. Added <server name> argument to the INFO command
785 reply. Updated the protocol specs.
787 * Fixed minor bug in silc_idcache_purge to not purge if the
788 expire value is zero.
790 * Fixed various bugs in WHOIS and IDENTIFY command handling as
791 they were buggy because of the WHOWAS information.
793 * Fixed local command MSG to handle the async resolving of
794 the remote client properly. It used to fail the first MSG.
795 Affected file silc/local_command.c.
797 * Added `data_len' field to SilcIDCache context.
799 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Update TODO. Todo in commands in the server.
803 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
806 used by routers as broadcast packet to inform other routers
807 about the changed user mode.
809 Implemented the notify handling in the server. Affected file is
810 silcd/packet_receive.c. Added the function
811 silc_server_send_notify_umode to the silcd/packet_send.[ch].
813 * Added new generic Channel Payload and deprecated the New Channel
814 Payload. The New Channel Payload is now the generic Channel
817 * Added new argument `mode' to the silc_server_send_new_channel
818 as it is required in the Channel Payload now.
820 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
821 and created a new and real SilChannelPayload to represent the
822 new generic Channel Payload. Implemented the encode/decode
823 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
825 * Added silc_server_get_client_channel_list to return the list
826 of channels the client has joined for WHOIS command reply.
827 Affected file silcd/server.[ch].
829 * Implemented the channel list sending in the WHOIS command reply
830 in server and in the client.
832 Implemented the channel list displaying on the user interface
833 as well. Affected file silc/client_ops.c.
835 * Added silc_channel_payload_parse_list to parse list of Channel
836 Payloads. It returns SilcDList list of SilcChannelPayloads.
837 Client for example can use this function to parse the list of
838 channels it receives in the WHOIS command reply. The caller
839 must free the list by calling silc_channel_payload_list_free.
840 Affected files lib/silccore/silcchannel.[ch].
842 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Added one new argument <user mode> to the WHOIS command reply
845 to return the mode of the user in SILC. Updated the protocol
848 Implemented it to the server and client.
850 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Fixed the mode printing on the user interface on joining.
853 Affected file silc/client_ops.c.
855 * Implemented the UMODE command and user modes in general to the
856 client library and to the user interface.
858 * Implemented the UMODE command to the server.
860 * The server now sends UNKNOWN_COMMAND error status if client sends
861 unknown command. Affected file silcd/command.c.
863 * All server commands now handle the command identifier the right
864 way when sending the command reply to the client. The client can
865 use to identify the command replies with the identifier.
867 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Added silc_server_get_client_route to resolve the route to
870 the client indicated by the client ID. Affected file is
873 * Added silc_server_relay_packet as general function to relay
874 packet to arbitrary destination. This deprecates functions
875 like _send_private_message_key, _relay_notify etc. Affected
876 file is silcd/packet_send.[ch].
878 Removed silc_server_send_key_agreement,
879 silc_server_send_private_message_key and
880 silc_server_packet_relay_notify functions from the file
881 silcd/packet_send.[ch].
885 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
886 server. Affected file silcd/packet_receive.[ch].
888 * Implemented the KILL command to the client. Implemented the
889 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
890 Affected files lib/silcclient/command[_reply].c and
891 lib/silcclient/client_notify.c. Implemented the KILL notify
892 printing in the user inteface.
894 * Fixed a lot silc_parse_nick memory leaks from the client
895 library in the file lib/silcclient/command.c.
897 * Changed the silc_server_send_notify_on_channels's `sender'
898 argument from SilcSocketConnection to SilcClientEntry to
899 check the sender as entry and not as connection object and not
900 to send to the client provided as argument. The affected file
901 is silcd/packet_send.[ch].
903 * The notify packets that are destined directly to the client used
904 to not to be processed by the server. Now changed that and the
905 server processes all notify packets. After relaying the packet
906 to the client the notify packet is processed in the server.
908 * The silc_server_free_client_data now checks whether there is
909 pending outgoing traffic for the client and purges the data to
910 the network before removing the client entry.
912 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
915 an client is killed from the SILC Network. Updated the protocol
918 Added new function silc_server_send_notify_killed to the
919 silcd/packet_send.[ch].
921 * Added function silc_server_packet_relay_notify to relay notify
922 packets that are destined directly to a client. In this case
923 the server does not process the notify packets but merely relays
924 it to the client. Affected file silcd/packet_send.[ch].
926 Added also silc_server_packet_process_relay_notify to check
927 whereto relay the notify. Affected file is
928 silcd/packet_receive.[ch].
930 * Implemented the KILL command to the server.
934 * Added the backup schema desgined last fall to the protocol
935 specs for everyone to see. The specification is in the
936 *-spec-xx.txt draft and the packet type definitions for the
937 backup routers is in *-pp-xx.txt draft. Thusly, added also
938 new packet type SILC_PACKET_CELL_ROUTERS.
940 * A big security problem in the implementation discovered. The
941 signoff of an client did not cause new channel key generation
942 which it of course should've done. The channel keys must be
943 always re-generated when client leaves (or signoffs) the channel.
944 The silc_server_remove_from_channels funtion now handles
945 the channel key re-generation.
947 * Added `sender' argument to the silc_server_send_notify_on_channels
948 to not to send the client provided as argument. Affected file
949 silcd/packet_send.[ch].
951 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Implemented OPER and SILCOPER commands into the server and
956 * Added silc_auth_verify and silc_auth_verify_data to verify
957 the authentication directly from the authentication payload.
958 It supports verifying both passphrase and public key based
959 authentication. Affected file lib/silccore/silcauth.[ch].
961 * Added `hash' field to the SilcIDListData structure. It is the
962 hash negotiated in the SKE protocol. Affected file is
965 * Slight redesigning of the SilcAuthPayload handling routines.
966 Do not send SilcPKCS but SilcPublicKey as argument.
968 * Implemented the public key authentication support to the
969 serverconfig. The public key is loaded from the provided path
970 and saved as authentication data to void * pointer. Thus,
971 changed the unsigned char *auth_data to void *auth_data;
973 * Fixed SHUTDOWN command to send the reply before the server
974 is shutdown. :) Affected file silcd/command.c.
976 * Fixed fatal bug in CONNECT command. The hostname was invalid
977 memory and server crashed. Affected file silcd/command.c.
979 * Fixed fatal bug in CLOSE command. The server_entry became
980 invalid but was referenced later in the command. Affected file
983 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Fixed fatal bug in failure packet handling. Server ignored
986 the failure and thus crashed when it came.
990 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
993 that the command may be executed only once in (about) 2 seconds.
994 The old SILC_CF_LAG flag is same but allows command bursts up
995 to five before limiting.
997 Added the support for CF_LAG and CF_LAG_STRICT flags to the
998 server code. Various commands now includes the CF_LAG_STRICT
999 flag to disallow any kind of miss-use of the command.
1001 * Fixed the silc_buffer_unformat to not to allocate any data
1002 if the length of the data is zero. It used to allocate the
1003 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1005 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Changed the format of AdminConnection configuration section
1008 in the server. Added username of the admin to the format.
1009 Affected files silcd/serverconfig.[ch].
1011 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1012 to return admin configuration data by host, username and/or
1015 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * Implemented WHOWAS command to the server. Added the functions:
1019 silc_server_command_whowas_parse,
1020 silc_server_command_whowas_send_reply,
1021 silc_server_command_whowas_from_client and
1022 silc_server_command_whowas_from_server
1024 * Added <Client ID> argument to the WHOWAS command reply. Updated
1025 the protocol specs accordingly.
1027 * Implemented WHOWAS command and command_reply to the client
1030 Implemented the WHOWAS printing on the user interface.
1032 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Added new argument to the WHOWAS command reply, the real name.
1035 It is an optional argument. Updated the protocol specs.
1037 * Added SilcIDCacheDestructor callback that is registered when
1038 the SilcIDCache is allocated. The callback is called when
1039 an cache entry in the ID Cache expires, or is purged from the
1040 cache. Added into lib/silccore/idcache.[ch].
1042 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1043 to destruct the client entries when the cache entry expires.
1044 Other ID Cache's in server and in the client library ignores
1047 * If the ID Cache entry's `expire' field is zero then the entry
1048 never expires. Added boolean `expire' argument to the
1049 silc_idcache_add function in the lib/silccore/idcache.[ch].
1050 If it is TRUE the default expiry value is used.
1052 * Added silc_server_free_client_data_timeout that is registered
1053 when client disconnects. By default for 5 minutes we preserve
1054 the client entry for history - for WHOWAS command.
1056 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Added support to the server to enforce that commands are not
1059 executed more than once in 2 seconds. If server receives
1060 commands from client more frequently, timeout is registered
1061 to process the commands. Affected file silcd/command.c.
1062 Added new function silc_server_command_process_timeout.
1064 * Changed NICK_NOTIFY handling in client library to check that
1065 if the client's nickname was changed, so there is no need to
1066 resolve anything from the server.
1068 * Removed error printing from the WHOIS and IDENTIFY commands.
1069 If error occurs then it is ignored silently in the client library.
1070 The application, however, may map the received error to
1071 human readable error string. The application currently maps
1072 the NO_SUCH_NICKNAME error to string.
1074 * Made the command status message public to the application. Moved
1075 them from lib/silcclient/command_reply.c to
1076 lib/silcclient/command_reply.h. The application can map the
1077 received command status to the string with the
1078 silc_client_command_status_message function.
1080 * Added check to the server to check that client's ID is same
1081 as the Source ID in the packet the client sent. They must
1084 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Added dist-bzip hook to the Makefile.am to make bzip2
1087 compressed distributions.
1089 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Server now enforces the maximum length for the nickname and
1092 the channel as protocol specification dictates. 128 bytes for
1093 nickname and 256 bytes for channel name.
1095 * Moved the WHOIS printing to the application. The client libary
1096 does not print out the WHOIS information anymore, the application
1097 must do it. Renamed silc_client_command_reply_whois_print to
1098 the silc_client_command_reply_whois_save.
1100 The client's idle time is also sent to the application now, and
1101 the idle is shown on screen.
1103 * Added silc_client_command_reply_identify_save to save the
1104 received IDENTIFY entries.
1106 * Do not check for channel private keys in message sending and
1107 reception if the channel does not have the PRIVKEY mode set.
1108 Affected file lib/silclient/client_channel.c.
1110 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1112 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1113 just surfaced after chaning the JOIN procedure.
1115 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added silc_client_get_clients_by_list to get client entries
1118 from Client ID list, that is returned for example by JOIN
1119 and USERS command replies. The application should use this
1120 function for example when JOIN command reply is received to
1121 resolve the clients already on the channel (library does not
1122 do that anymore as USERS command reply is not used in the JOIN
1123 procedure anymore). Affected files lib/silcclient/silcapi.h and
1124 lib/silcclient/idlist.c.
1126 * JOIN command reply and USERS command reply returns now SilcBuffer
1127 pointers instead of unsigned char pointers when returning
1128 the client list and mode list.
1130 * Added <Client ID> argument to the JOIN command reply, mainly
1131 for the server to identify for which client the command was
1132 originally sent. Updated protocol specs accordingly.
1134 * Added SilcDlist private_key pointer to the SilcChannelEntry
1135 in the client to support the channel private keys. Affected
1136 file is lib/silcclient/idlist.h.
1138 * Added SilcChannelPrivateKey argument to the function
1139 silc_client_send_channel_message so that application can choose
1140 to use specific private ke if it wants to. If it is not provided,
1141 the normal channel key is used, unless private keys are set.
1142 In this case the first (key that was added first) is used
1143 as the encryption key.
1145 * Implemented the support for channel private key handling.
1146 Implemented the following functions:
1148 silc_client_add_channel_private_key,
1149 silc_client_del_channel_private_keys,
1150 silc_client_del_channel_private_key,
1151 silc_client_list_channel_private_keys and
1152 silc_client_free_channel_private_keys
1154 Affected file lib/silcclient/client_channel.c.
1156 * Added the support for the private keys in the channel message
1157 sending and encryption and in the message reception and
1158 decryption. Affected funtions are
1159 silc_client_send_channel_message and silc_client_channel_message.
1161 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Added SKE's key verify callback to the client library's
1164 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1166 * Removed the statement that server (or router) must send USERS
1167 command reply when joining to the channel so that the client
1168 knows who are on the channel. Instead, the client list and
1169 client's mode list is now sent in the JOIN command reply to the
1170 client who joined channel. This is better solution.
1172 * Added function silc_server_get_users_on_channel and function
1173 silc_server_save_users_on_channel to the silcd/server.[ch].
1175 * Removed function silc_server_command_send_users from the
1178 * Do not show topic on the client library anymore. The topic is
1179 sent in the command reply notify to the application and the
1180 application must show the topic now.
1182 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Added client searching by nickname hash into the IDENTIFY and
1185 WHOIS commands in the server as they were clearly missing from
1186 them. Affected file is silcd/command.c.
1188 * Fixed a bug in private message receiving in the client library.
1189 The remote ID was freed and it wasn't supposed, now it is
1192 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Minor fix to the channel payload; allocate the data area, as it
1195 needs to be of specific length.
1197 * If the key agreement port is zero then the operating
1198 system will define the bound port. Affected files are
1199 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1201 * Added new function silc_channel_payload_decrypt into the file
1202 lib/silccore/silcchannel.[ch].
1204 * Moved the channel message etc, check from silc_packet_decrypt
1205 to applications. The library calls now a generic
1206 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1207 when the packet is either normal or special. This was done to
1208 allow more wide range of checking that was not allowed when
1209 the code was in library. Now applications can do virtually any
1210 checks to the packet and return to the library the decision how
1211 the packet should be processed. Affected files are
1212 lib/silccore/silcpacket.[ch].
1214 Added silc_server_packet_decrypt_check to the server and
1215 silc_client_packet_decrypt_check to the client library.
1217 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1218 to send with specified source and destination information.
1220 * Channel message delivery between routers was broken after the
1221 channel key distribution was fixed earlier. The channel key
1222 was used be to distributed to other routers as well which is not
1223 allowed by the protocol. Now this is fixed and channel keys
1224 really are cell specific and the channel message delivery between
1225 routers comply with the protocol specification.
1227 * Fixed various commands in server to check also the global list
1228 for the channel entry and not just the local list. The affected
1229 file silcd/command.c.
1231 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1233 * Added assert()s to buffer formatting and unformatting routines
1234 to assert (if --enable-debug) when error occurs. Affected
1235 file: lib/silcutil/silcbuffmt.c.
1237 * Changed to auto-reconnect to check whether the remote host is
1238 router and register the re-connect timeout if it is. It used
1239 to check that whether we are normal server, but router must do
1240 auto-reconnect with another router as well. Affected file
1243 * Removed the [<key len>] option from CMODE command as the cipher
1244 name decides the key length, nowadays. See the defined ciphers
1245 from the protocol specification.
1247 * Added [<hmac>] option to the CMODE command to define the HMAC
1248 for the channel. Added SILC_CMODE_HMAC channel mode.
1250 * Added [<hmac>] option for the JOIN command so that user can
1251 select which HMAC is used to compute the MACs of the channel
1254 * Added Hmac field to the Channel Message Payload. The integrity
1255 of plaintext channel messages are now protected by computing
1256 MAC of the message and attaching the MAC to the payload. The
1257 MAC is encrypted. Now, it is clear that this causes some
1258 overhead to the size of the packet but rationale for this is that
1259 now the receiver can verify whether the channel message decrypted
1260 correctly and also when private keys are set for the channel the
1261 receiver can decrypt the packet with several keys and check from
1262 the MAC which key decrypted the message correctly.
1264 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1265 lib/silccrypt/silccipher.[ch].
1267 * Added silc_hash_len to return the digest length into the
1268 lib/silcrypt/silchash.[ch].
1270 * Rewrote parts of Silc Channel Payload interface in the
1271 lib/silccore/silcchannel.[ch]. The encode function now also
1272 encrypts the packet and parse function decrypts it.
1274 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Fixed a minor formatting bug in the SKE's key material processing.
1277 It actually might have processed the keys wrong way resulting
1280 * Redefined the mandatory HMAC algorithms and added new algorithms.
1281 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1282 and hmac-md5 truncated to 96 bits. The mandatory is now
1283 hmac-sha1-96. Rest are optional (including the one that used
1284 to be mandatory). Rationale for this is that the truncated HMAC
1285 length is sufficient from security point of view and can actually
1286 make the attack against the HMAC harder. Also, the truncated
1287 HMAC causes less overhead to the packets. See the RFC2104 for
1290 * Added new [hmac] configuration section. The SKE used to use
1291 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1292 is of course wrong. The official names that must be proposed in
1293 the SKE are the ones defined in the protocol specification
1294 (hmac-sha1-96 for example). The user can configure any hmac
1295 using any hash function configured in the [hash] section. At
1296 least, the mandatory must be configured.
1298 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1300 * Added HMAC list to the SKE proposal list. It has now both
1301 hash algorithm list and HMAC list. This makes the protocol
1302 incompatible with previous versions. The SKE now seems to work
1303 the way it is supposed to work, for the first time actually.
1305 * Defined plain Hash algorithms to the protocol specification.
1308 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Implemented support for key agreement packets into the server.
1311 Added functions silc_server_key_agreement and
1312 silc_server_send_key_agreement. Other than these functions,
1313 server has nothing to do with this packet.
1315 * Added support for private message key packets into the server.
1316 Added functions silc_server_private_message_key and
1317 silc_server_send_private_message_key.
1321 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1322 called in the protocol's final callback instead in the END
1323 protocol state. This makes a little more sense and in the same
1324 time in client we can use the same protocol routines for normal
1325 key exchange and to key agreement packet handling as well.
1327 * Added to both client's and server's KE protocol context the
1328 SilcSKEKeyMaterial pointer to save the key material. We will
1329 bring the key material to the protocol's final callback by doing
1330 this. The final callback must free the key material.
1332 * Added SKE's packet_send callback into client's KE protocol
1333 context so that the caller can choose what packet sending function
1334 is used. This way we can use different packet sending when
1335 doing normal SKE when doing key agreement packet handling (in
1336 the key agreement packet handling we do not want to encrypt
1339 * Implemented the responder side of the key agreement routines
1340 in the client. The client can now bind to specified port and
1341 accept incoming key negotiation. The key material is passed
1342 to the application after the protocol is over.
1344 * Implemented the processing of incoming Key Agreement packet
1345 in the client. Added function silc_client_key_agreement to
1348 * Implemented the intiator side of the key agreement routines
1349 in the client. The client can now initiate key agreement with
1350 another remote client. The key material is passed to the
1351 application after the protocol is over.
1353 * Created client_keyagr.c to include all the key agreement
1356 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1357 SILC_TASK_CALLBACK except that it is not static.
1359 * Created client_notify.c and moved the Notify packet handling
1360 from the client.[ch] into that file.
1362 * Created client_prvmsg.c and moved all private message and
1363 private message key routines from the client.[ch] into that file.
1365 * Create client_channel.c and moved all channel message and
1366 channel private key routines from the client.[ch] into that file.
1368 * Changed silc_client_get_client_by_id_resolve to resolve with
1369 WHOIS command instead of IDENTIFY command, in the file
1370 lib/silclient/idlist.c.
1372 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Implemented the SKE's responder side to the Client library.
1376 * When FAILURE is received to the protocol do not trust it
1377 blindly. Register a timeout to wait whether the remote closes
1378 the connection as it should do it, only after that process the
1379 actual failure. This was changed to both client and server.
1381 * Added client_internal.h to include some of the structures
1382 there instead of client.h in lib/silcclient/.
1384 * Added function silc_task_unregister_by_callback to unregister
1385 timeouts by the callback function.
1387 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Some "Incomplete WHOIS info" errors has been appearing on the
1390 log files. Took away the entry->userinfo check from WHOIS
1391 reply sending. The entry->userinfo is now " " if client did not
1392 provide one. I thought this was fixed earlier but something
1393 is wrong still. Let's see if the error still appears.
1395 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Fixed a minor bug in the login when the channel key is
1398 re-generated in the server. It used to generate the key in
1399 wrong order and thus caused problems in the channel traffic.
1401 * Fixed a minor bug in channel key distsribution after
1402 KICK command. The key was not sent to the router even though
1405 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Added silc_ske_process_key_material_data as generic routine
1408 to process any key material as the SILC protocol dictates. The
1409 function is used by the actual SKE library but can be used by
1410 applications as well. This relates to the private message keys
1411 and the channel private keys since they must be processed the
1412 same way the normal SILC session keys. The protocol dictates
1413 this. Affected files: lib/silcske/silcske.[ch].
1415 Added also silc_ske_free_key_material to free the
1416 SilcSKEKeyMaterial structure.
1418 * Defined silc_cipher_set_key function to set the key for
1419 cipher without using the object's method function. The affected
1420 files: lib/silccrypt/silccipher.[ch].
1422 * Implemented silc silc_client_add_private_message_key,
1423 silc_client_add_private_message_key_ske,
1424 silc_client_del_private_message_key,
1425 silc_client_list_private_message_keys and
1426 silc_client_free_private_message_keys functions in the
1429 Added functions silc_client_send_private_message_key to send
1430 the Private Message Key payload and silc_client_private_message_key
1431 to handle incoming Private Message Key payload.
1433 * Added Cipher field to the Private Message Key payload to set
1434 the cipher to be used. If ignored, the default cipher defined
1435 in the SILC protocol (aes-256-cbc) is used.
1437 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1439 * Removed lib/silcclient/ops.h file.
1441 Redefined parts of the SILC Client Library API. Created new
1442 file silcapi.h that deprecates the ops.h file and defines the
1443 published Client Library API. Defined also private message key
1444 API and channel private key API into the file.
1446 This is the file that the application must include from the
1447 SILC Client Library. Other files need not be included by
1448 the application anymore.
1450 * Added new key_agreement client operation callback and also
1451 defined the Key Agreement library API for the application.
1453 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1456 is used by clients to request key negotiation between another
1457 client in the SILC network. If the negotiation is started it
1458 is performed using the SKE protocol. The result of the
1459 negotiation, the secret key material, can be used for example
1460 as private message key.
1462 Implemented the Key Agreement payload into the files
1463 lib/silccore/silauth.[ch].
1465 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Redefined ciphers for the SILC protocol. Added some new ciphers
1468 and defined the key lengths for the algorithms. Changed the
1469 code accordingly. The default key length is now 256 bits.
1471 * Fixed SKE key distribution function silc_ske_process_key_material
1472 when the key length is more than 128 bits. The default key
1473 length in SILC is now 256 bits.
1475 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1476 to indicate unsupported algorithm.
1478 * Renamed rijndael.c to aes.c and all functions as well.
1480 * Fixed a long standing channel key setting bug in client library.
1481 Weird that it has never surfaced before.
1483 * Fixed bug in channel deletion. If the entire channel is removed
1484 then it must also delete the references of the channel entry
1485 from the client's channel list as the client's channel entry and
1486 the channel's client entry share same memory.
1488 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Implemented CONNECT and SHUTDOWN commands in the client.
1492 * Implemented CLOSE command to the client.
1494 * Added the function silc_idlist_find_server_by_name into the
1495 files silcd/idlist.[ch].
1497 Added the function silc_idlist_find_server_by_conn into the
1498 files silcd/idlist.[ch].
1500 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * DIE command was renamed to SHUTDOWN. Updated the both code
1505 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1506 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1508 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1511 * Added function silc_server_create_connection function to create
1512 connection to remote router. My server implementation actually
1513 does not allow router to connect to normal server (it expects
1514 that normal server always initiates the connection to the router)
1515 so the CONNECT command is only good for connecting to another
1518 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1521 or some other client was kicked from the channel.
1523 Implemented the handling of the notify type to both client
1526 Implemented silc_server_send_notify_kicked to send the KICKED
1527 notify. It is used to send it to the server's primary router.
1529 * Implemented the KICK command into server and client.
1531 * Added `query' argument to the silc_idlist_get_client function
1532 to indicate whether to query the client from server or not if
1535 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1536 to indicate that the client is not channel founder.
1540 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Removed the rng context from SilcPacketContext structure and
1543 changed that the packet routine uses the Global RNG API.
1545 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Added support for quit message that client can "leave" on the
1548 channel when it quits the SILC. It is ditributed inside the
1549 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1551 Added silc_server_free_client_data that will take the
1552 signoff message as argument.
1554 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1556 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Updated parts of the protocol specification to keep it up
1561 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1564 payloads in one packet.
1566 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1567 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1568 use now the new List flag.
1570 * Also deprecated the following packet types: REPLACE_ID,
1571 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1573 * Added list support for Notify packet in server.
1575 * Added silc_server_send_notify_channel_change to send the
1576 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1577 the silc_server_send_replace_id.
1579 * Added silc_server_send_notify_nick_change to send the
1580 NICK_CHANGE notify type. Deprecates the function
1581 silc_server_send_replace_id.
1583 * Added silc_server_send_notify_join to send the JOIN notify type.
1584 Deprecates the function silc_server_send_new_channel_user.
1586 * Added silc_server_send_notify_leave to send LEAVE notify type.
1587 Deprecates the function silc_server_send_remove_channel_user.
1589 * Added silc_server_send_notify_cmode and
1590 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1591 types. Deprecates the silc_server_send_set_mode function.
1593 * Added SERVER_SIGNOFF notify type to indicate that server has
1594 quit. This means that all clients on the channel from that
1595 server will drop. This can be also used when netsplit happens.
1597 Deprecated REMOVE_ID packet type since it is not needed anymore
1600 Added silc_server_send_notify_server_signoff to send the
1601 SERVER_SIGNOFF notify type. Deprecates the function
1602 silc_server_send_remove_id.
1604 Added also silc_server_send_notify_signoff to send the
1605 SIGNOFF notify type.
1607 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1608 SILC protocol from this day on. Changed the protocol
1609 specification as well.
1611 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1612 notify type. It is used between routers to notify about
1613 topic changes on a channel.
1615 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1618 * Partly updated the protocol specification to comply with the
1619 changes now made. It is still though a bit outdated.
1621 * The JOIN notify type now takes one extra argument <Channel ID>.
1622 The packet used to be destined to the channel but now the
1623 JOIN type may be sent as list thus it is impossible to
1624 destine it to any specific channel. By adding this argument
1625 it is again possible.
1627 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Added CREDITS file. The CHANGES and CREDITS file will appear
1630 in the distribution as well.
1632 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1635 types in the server's silcd/packet_receive.c.
1637 * Implemented CMODE and CUMODE to work in router environment.
1639 * Fixed minor encoding and decoding buglet from the
1640 lib/silccore/silcmode.c.
1642 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1645 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1647 * Changed all SilcConfigServer* and silc_config_server* to
1648 SilcServerConfig* and silc_server_config*, respectively.
1651 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Associated the ID (client or server ID) to the Authentication
1654 Payload to avoid any possibility of forging. Updated the
1655 protocol specification and the code accordingly.
1657 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * The RSA key length is now save to the RsaKey context in the
1660 key generation process in lib/silccrypt/rsa.c. The key length
1661 is now used to figure out the maximum size of the block allowed
1662 to be encrypted/signed.
1664 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1665 is equivalent to the silc_mp_mp2bin but does not allocate any
1668 * Changed silc_mp_mp2bin API to take length argument. If it is
1669 non-zero then the buffer is allocated that large. If zero, then
1670 the size is approximated using silc_mp_sizeinbase, which however
1673 * Created Global RNG API which is global RNG that application can
1674 initialize. After initializing, any routine anywhere in the
1675 code (including library) can use RNG without allocating a new
1676 RNG object. This was done to allow this sort of use of the
1677 RNG in code that has no chance to allocate RNG object. All
1678 applications currently allocate this and many routines in the
1679 library use this. Affected file lib/silccrypt/silcrng.[ch].
1681 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1682 it to use the Global RNG API.
1684 * Defined Authentication Payload into protocol specification that
1685 is used during SILC session to authenticate entities. It is
1686 used for example by client to authenticate itself to the server
1687 to obtain server operator privileges.
1689 Implemented this payload into the lib/silccore/silcauth.[ch].
1690 Implemented also routines for public key based authentication
1691 as the new protocol specification dictates.
1693 Moved definitions of different authentication methods from
1694 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1696 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1697 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1698 silc_pkcs_verify_with_hash functions into the file
1699 lib/silccrypt/silcpkcs.[ch].
1701 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * The client entry's userinfo pointer must be always valid.
1704 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1705 will fail since it requires the userinfo. Now, the userinfo
1706 is allocated as "" if actual userinfo does not exist. Actually,
1707 it must exist and it is totally Ok to drop client connections
1708 that does not announce the userinfo. However, we will make
1709 this workaround for now.
1711 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1712 to return the remote port by socket.
1714 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1717 SILC_SERVER_PENDING_EXEC and added an new macro
1718 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1719 data or when error occurs while processing the pending command.
1721 Added new argument `destructor' into silc_server_command_pending
1722 and to the SilcServerCommandPending object. This destructor is
1723 now called after calling the pending callback or if error occurs
1724 immediately. If error occurs the actual pending callback won't
1725 be called at all - only the destructor. The destructor may be
1726 NULL if destructor is not needed.
1728 All this applies for client library code as well. Similar
1729 changes were made there as well for the pending commands.
1731 In the client, the application must now allocate the
1732 SilcClientCommandContext with the silc_client_command_alloc
1735 * Added reference counter to the SilcServerCommandContext. Added
1736 function silc_server_command_alloc and silc_server_command_dup
1739 Same type of functions added to the client library for the same
1742 * Removed the cmd_ident from IDListData away since it is now
1743 global for all connections. It is the command identifier used
1744 in command sending and with pending commands. The affected file
1747 * Added reference counter to the SilcSocketConnection objecet to
1748 indicate the usage count of the object. The object won't be
1749 freed untill the reference counter hits zero. Currently only
1750 server uses this, and client ignores it. The client must be
1751 set to use this too later. The affected files are
1752 lib/silccore/silcsockconn.[ch]. Added also the function
1753 silc_socket_dup to increase the reference counter.
1755 This was mainly added because it is possible that the socket
1756 is removed underneath of pending command or other async
1757 operation. Now it won't be free'd and proper DISCONNECTING
1758 flags, etc. can be set to avoid sending data to connection that
1759 is not valid anymore.
1761 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1762 the connection. After that it sets SILC_SET_DISCONNECTED.
1763 It is, however, possible that the socket data is not still freed.
1764 The silc_server_packet_process now checks that data is not
1765 read or written to connection that is DISCONNECTED. The socket
1766 get's freed when the reference counter hits zero.
1768 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Changed the client operation API: channel_message operation's
1771 `sender' is now the client entry of the sender, not the nickname
1772 and the `channel' is the channel entry, not the channel name.
1774 In the private_message operation the `sender' is now also the
1775 client entry of the sender not the nickname.
1777 Affected file is lib/silcclient/ops.h and all applications
1778 using the client operations.
1780 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Moved the calling of ops->connect() from connect_to_server_final
1783 into receive_new_id functin since that is the point when the
1784 client is actually allowed to send traffic to network. The
1785 affected file is lib/silcclient/client.c.
1787 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1790 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1791 (if needs broadcasting) instead of broadcasting the packets one
1792 by one which would make a burst in the network traffic.
1794 * Added `broadcast' argument to the functions in silcd/server.[ch]
1795 silc_server_create_new_channel[_with_id] to indicate whether
1796 to send New Channel packet to primary router.
1798 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Added new function into the silcd/server.[ch] files:
1801 silc_server_create_new_channel_with_id to create new channel with
1802 already existing Channel ID.
1804 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1805 lib/silccore/silcpacket.h. This packet is used t send list of
1806 Set Mode payloads inside one packet. Server uses this to set
1807 the modes for the channels and clients on those channels, that it
1808 announced to the router when it connected to it. The protocol
1809 specification has been updated accordingly.
1811 * The silc_server_new_channel did not handle the packet coming
1812 from normal server as it normally does not send that. However,
1813 when it announces its channels it does send it. Implemented
1814 the support for that.
1816 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1817 into the file lib/silccore/id.h.
1819 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Fixed memory leaks in the functions silc_idlist_del_client,
1822 silc_idlist_del_channel and silc_idlist_del_server in the file
1823 silcd/idlist.c. All of those leaked like a sieve.
1825 * Fixed some small memory leaks in the client's function
1826 silc_client_notify_by_server.
1828 * Added functions into silcd/server.c: silc_server_announce_clients,
1829 silc_server_announce_channels and silc_server_announce_server.
1830 These functions are used by normal and router server to announce
1831 to its primary router about clients, channels and servers (when
1832 router) that we own. This is done after we've connected to the
1835 These functions effectively implements the following packet types:
1836 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1837 and SILC_PACKET_NEW_ID_LIST.
1839 * Added new functions into the silcd/packet_receive.[ch]:
1840 silc_server_new_id_list, silc_server_new_channel_list and
1841 silc_server_new_channel_user_list to handle the incoming
1842 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1844 * Added support of changing Channel ID in the function
1845 silc_server_replace_id. If the server that announces a channel
1846 to the router already exists in the router (with same name but
1847 with different Channel ID), router is responsible to send
1848 Replace ID packet to the server and force the server to change
1849 the Channel ID to the one router has.
1851 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1852 client that the Channel ID has been changed by the router. The
1853 normal server sends this to the client. Client must start using
1854 the new Channel ID as the channel's ID.
1856 Implemented handling of this new type into lib/silcclient/client.c
1857 into the function silc_client_notify_by_server.
1859 * Added new function silc_idlist_replace_channel_id into the files
1860 silcd/idlist.[ch] to replace the Channel ID.
1862 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Call silc_server_command_identify_check always when processing
1865 the IDENTIFY command in silcd/command.c
1867 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1870 send keepalive packets. The packet can be sent by clients,
1871 servers and routers.
1873 Added function silc_socket_set_heartbeat into the file
1874 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1875 If not set, the heartbeat is not performed. The actual
1876 heartbeat is implemented in the low level socket connection
1877 library. However, application is responsible of actually
1880 Added silc_server_send_heartbeat to send the actual heartbeat
1881 packet into silcd/packet_send.[ch]. Server now performs
1882 keepalive with all connections.
1884 * Added silc_task_get_first function into lib/silcutil/silctask.c
1885 to return the timeout task with shortest timeout. There was a bug
1886 in task unregistration that caused problems. TODO has been
1887 updated to include that task system must be rewritten.
1889 * The client library will now resolve the client information when
1890 receiving JOIN notify from server for client that we know but
1891 have incomplete information.
1893 * Rewrote parts of silc_server_remove_from_channels and
1894 silc_server_remove_from_one_channel as they did not remove the
1895 channel in some circumstances even though they should've.
1897 * Encryption problem encountered in server:
1899 The LEAVE command used to send the Channel Key packet to the
1900 router immediately after generating it. However, the code
1901 had earlier sent Remove Channel user packet but not immediately,
1902 ie. it was put to queue. The order of packets in the router
1903 was that Channel Key packet was first and Remove Channel User
1904 packet was second, even though they were encrypted in the
1905 reverse order. For this reason, MAC check failed. Now, this
1906 is fixed by not sending the Channel Key packet immediately but
1907 putting it to queue. However, this is more fundamental problem:
1908 packets that are in queue should actually not be encrypted
1909 because packets that are sent immediately gets encrypted
1910 actually with wrong IV (and thus MAC check fails). So, packets
1911 that are in queue should be encrypted when they are sent to
1912 the wire and not when they put to the queue.
1914 However, the problem is that the current system has not been
1915 designed to work that way. Instead, the packet is encrypted
1916 as soon as possible and left to the queue. The queue is then
1917 just purged into wire. There won't be any fixes for this
1918 any time soon. So, the current semantic for packet sending
1921 o If you send packet to remote host and do not force the send
1922 (the packet will be in queue) then all subsequent packets to the
1923 same remote host must also be put to the queue. Only after the
1924 queue has been purged is it safe again to force the packet
1927 o If you send all packets immediately then it safe to send
1928 any of subsequent packets through the queue, however, after
1929 the first packet is put to queue then any subsequent packets
1930 must also be put to the queue.
1932 Follow these rules and everything works fine.
1934 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added new function silc_server_remove_clients_by_server to
1937 remove all client entries from ID list when the server connection
1938 is lost. In this case it is also important to invalidate all
1939 client entires as they hold the invalid server entry. This
1940 fixes fatal bug when server has lost connection and will reconnect
1943 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Made some sanity checks to silc_server_daemonise like to check
1946 whether the requested user and group actually exists.
1948 * Added sanity check to SKE's silc_ske_responder_finish to check
1949 that the public and private key actually is valid.
1951 * Invalidate the client's nickname when receiving Replace ID
1952 packet and the Client ID is being replaced. This means that the
1953 server will query the nickname if someone needs it (client)
1956 * Sort the ID Cache in client library when the ID Cache data
1957 has changed (needs sorting).
1959 * Do not allow for SILC client to create several connections to
1960 several servers. The client does not support windows right now
1961 and generating multiple connections causes weird behaviour.
1963 Irssi-silc client does support windows and can handle several
1964 connections without problems, see: www.irssi.org and SILC plugin.
1966 * Fixed some places where client was added to the IDList. The
1967 rule of thumb is following (in order to get everything right):
1968 If the client is directly connected local client then the
1969 `connection' argument must be set and `router' argument must be
1970 NULL to silc_idlist_add_client function. If the client is not
1971 directly connected client then the `router' argument must
1972 bet set and the `connection' argument must be NULL to the
1973 silc_idlist_add_client function.
1975 * The funtion silc_server_packet_send_local_channel actually did
1976 not check whether the client was locally connected or not. It
1977 does that now. Fixed a bug related to LEAVE command.
1979 * Fixed Remove Channel User payload parsing bug in server's
1980 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1982 * The server's silc_server_save_channel_key now checks also the
1983 global ID list for the channel as it might not be in the local
1984 list. Fixed a bug related to LEAVE command.
1986 * Is this the end of the [<unknown>] buglet that has been lurking
1987 around for a long time? A little for loop fix in server's
1988 silc_server_command_whois_parse that is used by both IDENTIFY
1989 and WHOIS command. At least, this was a clear bug and a cause
1990 of one type of [<unknown>] buglet.
1992 * WHOIS and IDENTIFY commands call the function
1993 silc_server_command_[whois/identify]_check function even if
1994 we are not router server.
1996 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1998 * Added --with-gmp configuration option. If set the GMP
1999 is always compiled in the SILC source tree. If not set then
2000 it is checked whether the system has the GMP3 installed. If
2001 it has then the GMP won't be compiled (the system's headers
2002 and library is used), if it doesn't have it then the GMP is
2003 compiled in the SILC source tree.
2005 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Changed RSA private exponent generation to what PKCS #1
2008 suggests. We try to find the smallest possible d by doing
2009 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2010 not security fix but optimization.
2012 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Added new config entry [Identity] to fork the server and run
2015 it as specific user and group. A patch from Bostik.
2017 * Imported Dotconf configuration library into lib/dotconf.
2018 This will be used to create the SILC configuration files later.
2019 It will appear in the distsribution after this commit.
2021 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * A big code auditing weekend happening. Auditing code for
2024 obvious mistakes, bugs and errors. Also, removing any code
2027 Removed files for being obsolete:
2029 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2030 inline in the file lib/silcutil/silcbuffer.h)
2032 o lib/silcutil/silcbufutil.c (the header has inline versions)
2034 Changed code to fix possible error conditions:
2036 o The buffer formatting routines now check that the destination
2037 buffer really has enough space to add the data. This applies for
2038 both buffer formatting and unformatting
2039 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2040 unformatting was changed to accomodate following rules:
2041 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2042 sent to the function while XXX_*STRING will not allocate or copy
2043 the data into the buffer. Instead it sets the pointer from the
2044 buffer into the pointer sent as argument (XXX_*STRING used to
2045 require that the pointer must be allocated already). This change
2046 makes this whole thing a bit more consistent and more optimized
2047 (note that the data returned in the unformatting with XXX_*STRING
2048 must not be freed now). The routines return now -1 on error.
2050 o Tried to find all code that use buffer_format and buffer_unformat
2051 and added return value checking to prevent formatting and
2052 especially unformatting errors and possible subsequent fatal
2055 o Changed ske->x and ske->KEY to mallocated pointers in
2056 lib/silcske/silcske.h. Fixed possible data and memory leak.
2058 o Added return value checking to all *_parse* functions. Fixed
2059 many memory leaks as well.
2061 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2062 so that buffer overflows would not happen. All code now also
2063 checks the return value as it can fail.
2065 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Added reconnection support to server if the normal server looses
2068 its connection to the router (for example if router is rebooted).
2069 The server performs normal reconnection strategy implemented
2070 to the server. Affected file silcd/server.c.
2072 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * Added new packet type SILC_PACKET_SET_MODE that is used to
2075 distribute the information about changed modes (for clients,
2076 channels and clients channel modes) to all routers in the
2077 network. Updated the protocol specification accordingly.
2079 Added functions into silcd/packet_send.c and
2080 silcd/packet_receive.c: silc_server_send_set_mode,
2081 silc_server_set_mode.
2083 Added new files silcmode.[ch] into lib/silccore that implements
2084 the encoding and decoding of Set Mode Payload. Added new type
2085 SilcSetModePayload. Moved the definitions of different modes
2086 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2088 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Oops, a little mistake in server's connection authentication
2091 protocol. The protocol is not ended with FAILURE but with
2092 SUCCESS if the authentication is Ok. :) Affected file is
2095 * Implemented NICK_CHANGE notify handling in server in the file
2096 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2097 the local clients on the channel. After the changing nickname
2098 in router environment snhould work and the [<unknown>] nickname
2099 should appear no more.
2101 The silc_server_replace_id function that receives the Replace ID
2102 payload now sends the NICK_CHANGE notify type also in the file
2103 silcd/packet_receive.c
2105 * Changed WHOIS and IDENTIFY command to support the maximum amount
2106 of arguments defined in protocol specs (3328 arguments). This
2107 fixed a bug that caused problems when there were more than three
2110 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added extra parameter, command identifier, to the
2113 silc_client_send_command so that explicit command identifier
2116 Changed that ID list routines uses specific command identifier
2117 when sending WHOIS/IDENTIFY requests to the server so that they
2118 can be identified when the reply comes back.
2120 Affected files lib/silcclient/command.[ch],
2121 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2123 * Added `sender' argument to silc_server_packet_send_to_channel
2124 to indicaet the sender who originally sent the packet to us
2125 that we are now re-sending. Ignored if NULL. Affected file
2126 silcd/packet_send.[ch].
2128 * Added some server statistics support in silcd/server_internal.h
2129 SilcServerStatistics structure and around the server code. Also
2130 send some nice statistics information when client is connecting
2133 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Fixed channel ID decoding in server's JOIN command reply in
2136 silcd/command_reply.c
2138 * Fixed braodcasting of replace ID payload to not to send it if
2139 we are standalone server in silcd/packet_receive.c.
2141 * Fixed all channel message sending routines to not to send
2142 packets to clients that has router set, since they are routed
2143 separately in the same function earlier. Affects file
2144 silcd/packet_send.c and all channel packet sending functions.
2146 * In USERS reply, res_argv[i] are not allocated, the table
2147 is allocated. Thus changed that free the table, not its
2150 * In server's whois_check and identify_check if the client is
2151 locally connected do not send any WHOIS commands - they are not
2154 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Fixed some minor bugs in client when sending WHOIS command. The
2157 arguments was in wrong order.
2159 * Removed statis function add_to_channel from server in
2160 silcd/command.c that was previously used with the joining but
2163 * Tested USERS command in router environment successfully with two
2164 routers, two servers and two clients.
2166 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Reorganized the USERS command and command reply in client library
2169 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2170 When the command is given by user we register a pending command
2171 callback that will reprocess the command after the reply has been
2172 received from the server. When reprocessing the packet we then
2173 display the information. Thus, the USERS information is displayed
2174 now in the command callback instead of in the command reply
2175 callback. The processing of the command is same as previously
2176 when server has sent the command reply in the JOINing process.
2178 * Added to USERS command in silcd/command_reply.c to join the client,
2179 we didn't use to know about, to the channel after we've created
2180 a client entry for it. Also, for clienet we did know already still
2181 check whether it is on the channel or not and add it if not.
2183 * Removed silc_server_command_join_notify as the function and its
2186 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Changed the client's pending command handling to the same as the
2189 server's pending command handling. It is also now possible to
2190 execute command reply functions from other command reply
2191 function as the function callbacks for commands and command
2192 replies are one and same. The pending commands are not static
2193 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2194 in client connection context. Thus, pending commands are server
2195 connection specific as it is convenient.
2197 Changed the function silc_client_command_pending and
2198 silc_client_command_pending_del and added new function
2199 silc_client_command_pending_check. Removed the
2200 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2203 * Added cmd_ident, current command identifier, to the client
2204 connection context in lib/silcclient/client.h to keep track on
2205 command identifiers used in command sending. Client's command reply
2206 function handling now supports the mandatory command identifiers.
2208 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2209 funtions in client to fully support pending command callbacks.
2211 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2212 as one of the arguments to the application in the command reply
2215 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2216 before first releasing SILC but came back. Now it is removed again
2217 and should come back nomore. The FORWARDED flag was used only
2218 by the JOINing procedure by forwarding the command packet to router.
2219 Now, the JOINing procedure has been changed to more generic (due
2220 to various router environment issues) and FORWARDED is not needed
2221 anymore for anything. The protocol specification is yet to be
2224 Now, removed silc_server_packet_forward from server and the flag
2225 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2227 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Renamed NAMES command to USERS command. The NAMES was named that
2230 due to historical reasons. Now it is renamed. Also, rewrote
2231 parts of the USERS command. The nickname list is not sent anymore
2232 by the server. Only Client ID and mode lists are sent in the USERS
2233 command. Changed this also to the protocol specification.
2235 The client now resolves the names and stuff after it receives
2236 the USERS list from the server when joining to the channel.
2238 * WHOIS and IDENTIFY commands has been changed to support multiple
2239 Client ID's per command. One can now search for multiple users
2240 in the network by sending only one WHOIS or IDENTIFY command.
2241 Changed the code and the protocol specifications.
2243 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2244 uses silc_server_command_whois_parse to parse the request. */
2246 * If normal server, do not parse the WHOIS and IDENTIFY requests
2247 before sending it to the router. Saves some time.
2249 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Fixed JOIN command on client library. Wrong number of arguments
2252 used to crash the client.
2254 * Added silc_server_channel_has_global function to check whether
2255 channel has global users or not.
2257 * Added silc_server_channel_has_local function to check whether channel
2258 has locally connected clients on the channel.
2260 * The silc_server_remove_from_one_channel now checks whether the
2261 channel has global users or not after given client was removed from
2262 the channel. It also checks whether the channel has local clients
2263 on the channel anymore. If it does not have then the channel entry
2264 is removed as it is not needed anymore.
2266 * The silc_server_notify now checks on JOIN notify whether the joining
2267 client is one of locally connected or global. If it is global then
2268 the channel has now global users on the channel and that is marked
2269 to the channel entry. Also, it now saves the global client to
2270 global list who is joining and JOINs it to the channel. This is
2271 for normal server, that is.
2273 Changed silc_server_send_notify_on_channel,
2274 silc_server_packet_relay_to_channel and
2275 silc_server_packet_send_to_channel check if we are normal server
2276 and client has router set (ie. global client) do not send the
2277 message to that client, as it is already routed to our router.
2279 * Implemented LEAVE notify type handling in silc_server_notify
2282 * Tested LEAVE command in router environment successfully. Tested
2283 with two routers, two servers and two clients.
2287 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2289 * Implemented SIGNOFF notify type handling in silc_server_notify
2292 * silc_server_remove_id now removes the client entry from all channels
2293 it has joined and thusly sends SIGNOFF notify type.
2295 * Rewrote the NAMES list generation in server by removing two excess
2296 loops. The lists are created now inside one loop.
2298 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * silc_server_remove_channel_user checks now also global list
2301 for channel and client.
2303 * silc_server_new_channel_user checks now both local and global
2304 list for channel and client. Fixed a bug in client id decoding.
2305 Used to decode wrong buffer.
2307 * silc_server_channel_message checks now both local and global
2308 list for channel entry.
2310 * Tested channel joining (hence JOIN) in router environment
2311 successfully. Tested with two routers, two servers and two
2314 * Tested channel message sending in router environment successfully.
2316 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added silc_server_save_channel_key into server.[ch] to save the
2319 received channel key in Channel Key payload processing. It is
2320 also used in JOIN command reply handling.
2322 Equivalent function silc_client_save_channel_key added into
2323 client.[ch] into client library.
2325 * Changed JOIN command reply to send information whether the channel
2326 was created or not (is existing already) and the channel key
2327 payload. Changed protocol specs accordingly.
2329 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2330 the request was sent by ID and not by nickname. Crashed on
2333 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2336 now correctly save the received data.
2338 * silc_server_free_sock_user_data now notifies routers in the
2339 network about entities leaving the network.
2341 At the same time implemented functions silc_server_remove_id
2342 and silc_server_send_remove_id to receive and send REMOVE_ID
2343 packets. The packet is used to notify routers in the network
2344 about leaving entities. The ID removed will become invalid in
2347 * Added function silc_idlist_del_server into server. Removes and
2348 free's server entry from ID list.
2350 * silc_server_private_message function now checks, if we are router,
2351 that the destination ID really is valid ID, naturally.
2353 * In router when NEW_ID packet is received (for new client) the
2354 hash of the Client ID is saved in the ID Cache but the
2355 client->nickname is set to NULL, instead of putting the hash
2358 IDENTIFY command now also checks that client->nickname must be
2359 valid. If it is not if will request the data from the server who
2360 owns the client. Added new function
2361 silc_server_command_identify_check.
2363 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2364 to set the command to already allocated Command Payload.
2366 * Tested private message sending in router environment with two
2367 routers, two servers and two clients. Fixed minor bugs and now
2370 * Fixed segfault from client's NAMES command. Used to crash if
2373 * Forwarded packets must not be routed even if it is not destined
2374 to the receiver. Changed server code comply with this.
2376 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Added `require_reverse_mapping' boolean value to ServerParams
2379 structure. If TRUE (not default) the server will require that
2380 the connecting host has fully qualified domain name.
2382 If the reverse mapping is not required and hostname could not be
2383 found the IP address is used as hostname.
2385 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Implemented version string checking to both client and server.
2388 The check is incomplete currently due to the abnormal version
2389 strings used in development version of SILC.
2391 * Changed all command functions in server to use the new
2394 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Changed char *data to unsigned char *data in ID Cache system to
2397 support binary data as ID Cache data. Changed code to support
2398 binary data in lib/silccore/idcache.c.
2400 * Renamed silc_server_packet_relay_command_reply to
2401 silc_server_command_reply as it is normal packet receiving
2402 function. Rewrote the function to accept command replys for
2403 servers and not only for clients.
2405 * Mark remote router always as registered server if we are connecting
2406 to it. Otherwise, commands sent by the router to us are ignored.
2408 * All ID List find routines now returns the ID Cache Entry pointer
2409 as well if requested.
2411 * WHOIS command works now in router environment, tested with two
2412 routers, two servers and two clients.
2414 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2415 in router environment (as it is almost equivalent to WHOIS) but
2416 hasn't been tested thoroughly. Added new functions:
2418 silc_server_command_identify_parse
2419 silc_server_command_identify_send_reply
2420 silc_server_command_identify_from_client
2421 silc_server_command_identify_from_server
2423 * Disabled route cache adding because adding two different ID's with
2424 same IP replaces the old cache entry thus giving wrong route.
2425 The entry->router->connection is always the fastest route anyway
2426 so route cache may not be needed. Of course, new routes maybe
2427 established after receiving the ID when the entry->router->connection
2428 might not be anymore the most optimal.
2430 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Add route cache for received ID for fast routing.
2434 * Added silc_server_packet_route to route received packet on router
2435 that is not destined to us.
2437 * Renamed silc_server_get_route to silc_server_route_get.
2439 * Added id_string and id_string_len fields into SilcServer to
2440 include encoded ServerID for fast comparing without excess
2441 encoding of the ID's.
2443 * Cleaned up WHOIS command on server side. Added following static
2446 silc_server_command_whois_parse
2447 silc_server_command_whois_check
2448 silc_server_command_whois_send_reply
2449 silc_server_command_whois_from_client
2450 silc_server_command_whois_from_server
2452 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2453 arguments in command replies. All command functions should be
2454 updated to use this macro.
2456 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2458 * Minor typo fixes on command reply handling on server.
2460 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Added silc_server_command_add_to_channel internal routine to add
2463 the client to the channel after router has created the channel and
2464 sent command reply to the server.
2466 * Added generic silc_server_send_command to send any command from
2469 * Use static buffer with ID rendering instead of duplicating data.
2471 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Fixed a channel user mode bug when joining to a channel server gave
2474 everybody channel founder rights, oops.
2476 * We mark ourselves as the router of the incoming server connection
2477 if we are router ourselves. This way we can check in some packet
2478 sending functions whether it is locally connected server. For
2479 incoming router connections we put NULL.
2481 * For router sending packets locally means now always sending the
2482 packet cell wide; to local clients and local servers. For normal
2483 server sending packet locally means sending it to only local
2486 * Fixed the JOIN command to really work in router environment. If the
2487 channel is created it is always created by the router. Router is
2488 also responsible of making the initial joining to the channel,
2489 sending JOIN notify to the sending server and distributing
2490 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2491 does not exist server doesn't do anything else but forward the
2492 command to the router which performs everything.
2494 * Added silc_server_send_channel_key function to send the Channel Key
2497 * Added silc_server_create_channel_key to create new channel key. The
2498 channel key is now re-generated everytime someone joins or leaves
2499 a channel, as protocol dictates. Note: channel->key_len is the
2502 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2505 packet_receive.[ch] to separate packet sending and receiving
2506 routines. The server.[ch] now includes everything else including
2507 actual packet processing (writing and reading data) and other
2510 Renamed silc_server_private_message_send_internal to
2511 silc_server_send_private_message. The routine is still though
2512 used only to relay private messages as server does not send
2513 private messages itself.
2515 Renamed silc_server_new_channel to silc_server_create_new_channel
2516 and added new function sicl_server_new_channel that handles the
2517 incoming New Channel packet. Added also new sending function
2518 silc_server_send_new_channel to send New Channel Payload.
2520 * Added new function silc_server_notify to process incoming notify
2521 packet to the server/router. Server may then relay the notify
2522 to clients if needed.
2524 * Added new function silc_server_new_channel_user to process incoming
2525 New Channel User packet. Router will redistribute the packet and
2526 send JOIN notify to its local clients and locally connected servers
2527 if needed. Normal server will send JOIN notify to its local client
2528 on same channel when received this packet. Added also corresponding
2529 sending function silc_server_send_new_channel_user to sent the
2532 * Added boolean route argument to send_notif_to_channel and
2533 packet_send_to_channel functions to attempt to route the packet
2534 if it is TRUE and send only locally if it is FALSE.
2536 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * silc_server_replace_id now broadcasts the received replace ID
2539 packet if it is not broadcast packet already. The router must
2540 broadcast to inform other routers about changed ID.
2542 * Added backpointer to server's router into SilcServer context in
2543 silcd/server_internal.h.
2545 * Fixed silc_server_packet_broadcast to send correct broadcast
2548 * The channel key is now distributed to the local client as soon
2549 as it is received from the router (in router environment) so that
2550 no other packet may be sent for the channel until client has
2553 * silc_server_remove_channel_user now broadcasts the received
2554 Remove Channel User packet if it is not broadcast packet already.
2555 The router must broadcast to inform other routers about removed
2558 * Added users field into SilcPacketContext that is a reference count
2559 of the context. One can increase the reference count by calling
2560 silc_packet_context_dup which is now changed to just increase the
2561 reference count instead of duplicating the data. The reference
2562 count is decresed by calling silc_packet_context_free that will
2563 free the data after the reference count hits zero.
2565 For now on the packet context and everything allocated into it
2566 (including the raw packet from network) must be freed by calling
2567 the new silc_packet_context_free function. Added also new function
2568 silc_packet_context_alloc that must be used now to allocate the
2569 context. This also means that if a routine is asynchronous from
2570 silc_[client/server]_packet_parse_type the packet context must
2571 be duplicated by calling silc_packet_context_dup. Otherwise it
2572 gets free'd after silc_[client/server]_packet_parse_type returns.
2573 Also, one must remember that if packet is duplicated then its
2574 reference count must be decresed by calling the free function as
2575 many times as it was duplicated.
2577 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2578 from both client and server.
2580 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Made joining to a channel working in router environment.
2584 * Cleaned up JOIN command on server side and create function
2585 silc_server_command_join_channel internal routine to make the
2588 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Changed silc_command_pending list to SilcDList. Also, added
2591 `ident' field to SilcServerCommandPending structure to identify
2592 the reply and to call correct callback.
2594 Added silc_server_command_pending_check function to replace the
2595 corresnponding macro. The silc_command_pending list is not
2598 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2599 to set identifier to previously allocated Command Payload. It
2600 is used to set identifier for command when resending Command
2603 * Added silc_command_payload_encode_payload to encode Command
2604 Payload buffer from SilcCommandPayload structure.
2606 * Added silc_argument_payload_encode_payload to encode Argument
2607 payload buffer from SilcArgumentPayload structure.
2609 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Changed WHOIS command to support router connection on server side.
2612 The whois request is always sent to router unless the server is
2613 standalone server. After server has received the reply from the
2614 router will it send the reply to the client.
2616 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2617 broadcast received broadcast packet. The function is used only
2618 by router. The broadcast packet is always sent to the router's
2621 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2622 render given ID to printable string, for log files for example.
2624 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Made basic router to router connections working. At least they
2627 can now connect to each other but nothing really works the way
2628 they are supposed - yet.
2630 * Added new initiator token to RouterConnection configuration
2631 file in silcd/serverconfig.[ch]. It is used to tell whether we
2632 are the initiator to the remote router or whether we'll expect
2633 the other end to connect.
2635 * Moved registering of listener task to silc_server_init, hence
2636 the server starts listenning as soon as it is run, even if it
2637 does not have connections to other routers. Let's see how well
2640 * Changed default connection retry timeouts for more suitable in
2643 * Removed cipher and such arguments from silc_idlist_add_client
2644 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2645 Added new function silc_idlist_add_data to add the keys and stuff
2648 * Added SilcIDListData structure and added it to SilcClientEntry
2649 and SilcServerEntry as their first field in the structure. This
2650 way we can explicitly cast the ID entries to the SilcIDListData
2651 structure and get common data for the entries. In past, we had
2652 to first check what type of connection it is and then cast it to
2653 correct ID entry type. Now, we can directly cast the opaque
2654 pointer to the SilcIDListData (no matter what ID entry it actually
2655 is) and get the data needed.
2657 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2660 in some circumstances even if threre were timeout tasks, though not
2661 IO tasks, but tasks anyway. Now fixed.
2663 * Defined SilcServerConnection structure to hold connection specific
2664 stuff about directly connected servers and routers. The definition
2665 is currently in silcd/server_internal.h. I thought about having
2666 a bit more important role fro this struct but for now it is used
2667 only when connecting to other server (or router actually).
2669 * Added connecting retry support in server when connecting to
2670 router(s). The retry feature implement exponential backoff
2671 algorithm. Also, added SilcServerParams structure to hold default
2672 parameters for server. For now, it include these retry settings
2673 and are hard coded. After server is moded to be as Silc Server
2674 Library this structure will be more important.
2676 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Changed client librarys channel->clients table to SilcList and
2679 changed code accordingly.
2681 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Changed client's channel table to SilcList and changed code
2684 accordingly. Also changed SilcChannelClientEntry to include back-
2685 pointer to the channel so that client entry can use that structure
2686 as list as well and we have fast cross-reference to the channel.
2687 This change dramatically decreased the complexity of channel
2688 handling with client entry and vice versa (removed one extra
2689 loop when searching for channel entry from many functions).
2691 * Changed server->sim from table to SilcDList and changed code
2694 * NAMES command can now be used from user interface. It will show
2695 the user list on the channel, neatly.
2697 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2698 Code now saves realname of the user if it becomes available.
2700 * Renamed configure.in to configure.in.pre and made ./prepare
2701 script to automatically add correct version string to
2702 configure.in which it creates from configure.in.pre.
2704 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * NAMES command reply now shows users mode with the nickname when
2709 * Moved silc_client_ch[u]mode[_char] functions from
2710 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2711 place sucks, they are utility functions and should be in some
2714 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2716 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2719 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added TRQ (efficient deque and list library) into lib/trq. This is
2724 a very good list library that is currently used in the SILC. Defined
2725 SilcList API over the library because I didn't like the API very
2726 much. See lib/trq/silclist.h for the API and examples of how to
2727 use the API. Fixed various places in the code to use the new
2728 SilcList API. The SilcList is meant for lists that has a structure
2729 already defined as a list. It is not suitable to add just some
2730 context to the list (in TRQ, the context is the list actually).
2732 So, I defined SilcDList that can be used for the purpose where
2733 predefined list structure does not exit. This can be used as
2734 such list. Now some context just can be added to the SilcDList.
2735 Currently this list is not used in the SILC just yet, though there
2736 are a lot places where this can replace dynamically allocated
2737 tables and I will fix these places, later, to use SilcDList.
2738 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2739 and use TRQ internally).
2741 Also fixed some annoying warning messages that the original TRQ
2742 code generated. Also minor changes to TRQ's Makefile.in.
2744 * Added support for querying by Client ID to both WHOIS and
2745 IDENTIFY commands into server, as required by the protocol.
2747 * Removed method function pointers from SilcBuffer structure. They
2748 weren't used to anything and just increased the context size for
2749 no good reason. This change also made silc_buffer_alloc and
2750 silc_buffer_free functions inline functions.
2752 * Disabled command flooding detection support until it's fixed so
2753 that it accepts commands in but does not execute them more than once
2756 * Added silc_net_localhost(), to return local hostname, into
2757 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2758 that must be initialized before calling silc_client_init.
2760 * Added new function: silc_server_send_notify_on_channels to send
2761 notify messages to all channels client has joined. It is assured
2762 that the message is sent only once per client.
2764 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2765 lib/silcutil/silcutil.[ch] as silc_format function. The new
2766 function is generic and is used by server as well, not only by
2767 the logging routines.
2769 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2770 the provided version string was not acceptable. Added new function:
2771 silc_ske_check_version into lib/silcske/silcske.h. The function
2772 must be implemented by the application (client or server) and it
2773 does not reside in the SKE library. The function checks the version
2774 string remote end sent.
2776 * Added back pointers (to opaque context and to SilcSocketConnection)
2777 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2779 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2780 duplicate packet context structure.
2782 * Changed `notify' client operation to send same arguments as client
2783 receives from server except for ID's. ID's are mapped to correct
2784 ID entry and that is returned. Also, if channel entry is not sent
2785 by server but the notify is for channel the channel entry is sent
2786 to application (otherwise application doesn't know that it is for
2787 channel (library gets it from packet's Destination ID)).
2789 * Added silc_client_remove_from_channels into client library to
2790 remove a client from all channels it has joined to. Used when
2791 received SIGNOFF notify from server. Added also new function
2792 silc_client_replace_from_channels to replace old ID entry with
2793 new ID entry on all channels. Used when received NICK_CHANGE
2796 * Fixed ID Cache list handling in silc_idlist_get_client in
2797 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2798 to get (or query) client by ID.
2800 * Updated TODO list.
2802 * Added connection authentication status message defined by the
2803 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2804 support for these into the code in client and server side.
2806 * Added generic function silc_client_send_command to send any command
2807 with variable argument list. Application should use this function
2808 to send commands if the command functions provided by the library
2809 does not suite for the application's user interface needs.
2811 * Added new `failure' client operation. Application is notified about
2812 received failure packet if client is executing a protocol. In this
2813 case the protocol's execution has failed.
2815 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2816 is required by the protocol.
2818 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2819 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2822 * Added status flag to SilcSKE object to indicate realtime status
2823 of the SKE protocol.
2825 * Application receives now exactly same command reply arguments as
2826 the library receives from server. However, if ID is received the
2827 corresponding ID entry is returned to the application (eg. Client
2828 ID is mapped to correct SilcClientEntry entry and that is returned).
2829 Changed command_reply client operation due to this change.
2831 * Changed all ID's in commands and in command replys as ID Payloads.
2832 Change affected both client and server side codes.
2834 All ID's sent in SILC network (with execption of ID's in SILC
2835 Packet header) are sent in ID Payload to support variable length
2838 * Server now notifies nick changes and notifies all clients on
2839 the channels about the new nickname (about the new Client ID,
2842 * Implemented CMODE command to change channel modes. Supports all
2843 channel modes defined by the protocol specs except ban and invite
2844 lists. (Also, private channel key mode is supported but support for
2845 setting private channel key in client is missing, thus, this mode
2846 has no effect on client side (except that server requires that the
2847 client uses private channel key and normal channel traffic does not
2850 Also, invite mode works per se, but INVITE command does not work
2851 yet correctly, so you can set channel as invite only channel but
2852 inviting clients to the channel does not work (it is yet to be
2853 thought what's the best way to do it).
2855 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2856 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2857 Implemented CUMODE command to change user's mode on the channel.
2858 Supports all modes defined by the protocol specs.
2860 * Added NAMES command reply to return users modes on the channel.
2862 * Removed unnecessary and slow ciphers from lib/silccrypt.
2864 * Set SO_KEEPALIVE option to connection sockets by default.
2866 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2868 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2869 redefined the Notify Payload into protocol specs.
2871 * Added silc_id_payload_parse_id to get ID directly from raw
2874 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2877 accept searching by Client ID as well.
2879 * Added support for LEAVE and SIGNOFF notify types in client library.
2881 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2882 to parse ID Payload from raw data.
2884 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Added flags parameter into silc_ske_assemble_security_properties
2887 function in lib/silcske/silcske.[ch].
2889 * Changed notify client operation to fit better for notify messages
2890 sent by server. The notify payload received from server is now
2891 passed to the application (after parsing it to SilcNotifyPayload).
2892 It is application's responsibility to retrieve the arguments
2893 from the payload and show the message the way it wants. The message
2894 sent by server is implementation specific.
2896 * Changed public keys to comply with the protocol specification.
2897 Old public keys are not supported anymore and are not compatible.
2899 * Removed nickname from Channel Payload as the latest draft removed
2900 it. The client must resolve the nickname from the NAMES command
2901 reply received when it joined the channel.
2903 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2905 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Fixed some errors in protocol specification drafts.
2909 * Created lib/silccore/silcnotify.c to implement Notify Payload
2910 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2911 generic payloads described by protocol specifications. The file
2912 includes implementations for ID Payload and Argument Payload.
2914 * Changed Command Payload implementation to use the new Argument
2915 Payload. Changed command_xxxx_payload to command_payload_xxxx
2916 to comply with SILC coding conventions.
2918 * Added suppport for Argument Payload handling in Notify Payload
2919 implementation as protocol requires it. Added the new support
2920 into server and client lib as well.
2922 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Added support for multiple nicknames on same channel. [n] is
2925 added locally to the nickname if there are more than one same
2926 nicknames on the channel.
2928 * Server now sends all nicknames that matched WHOIS request.
2929 Client also shows the list received from server.
2931 * Added TOPIC command to client side. User can now set and show
2932 current topic on channel.
2934 * Added MOTD command to client and server. Also, server sends the
2935 motd when client connects to the server.
2937 * Changed version strings to comply ISO 8601.
2939 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Fixed protocol error handling in client library. It should now
2942 cope even if the SKE fails for some reason.
2944 * Made new protocol specification drafts for submitting to IETF.
2946 * Implemented TOPIC command to server in silcd/command.c.
2948 * Added two new notify types into lib/silccore/silcnotify.h:
2949 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2950 notify nickname change and topic setting/change on a channel.
2952 * API change of command_reply operation in client library. The
2953 application gets now the status type received from server as well.
2955 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2959 * Cras fixed and optimized the packet handling even further and
2960 it should work now. Minor change to the prototype of function
2961 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2963 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Added new function into lib/silcutil/silcschedule.[ch]:
2966 silc_schedule_with_fd to select() a specified fd. The function
2967 returns after timeout expires or data arrives or goes. The
2968 function is used by packet routines to wait that all data is
2969 received from network.
2971 * Fixed data reading from network in lib/silccore/silcpacket.c.
2972 The code now assures that all data is read from the fd and then
2973 continues packet processing. This was a bug fix since the code
2974 used to drop some data in some circumstances.
2976 * Added new function into lib/silcclient/client.[ch]:
2977 silc_client_start_key_exchange to start key exchange after
2978 connection has been established to server. The code internally
2979 now uses this funtion but its main purpose was to provide it
2980 for applications that perform their own connecting. After
2981 application has created a connection it merely calls this
2982 function to start the key exchange between client and server.
2983 The library takes care of everything else after that.
2985 Updated also lib/silcclient/README to explain the usage of
2988 * Do not send to application information that connection has
2989 been established. Application gets notified it by connect
2992 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Applied cras's patch to add silc_schedule_one function. The
2995 function runs scheduler once and returns.
2997 * Fixed the scheduler after cras messed it up. The timeout
2998 handling works now as it's supposed to work.
3000 * Added into lib/silccore/ silcnotify.h to include notify
3001 message types support. Changed silc_server_send_notify*
3002 functions, in server.[ch], to support those new notify types.
3003 Added the support for the notify types into client library,
3004 as well. Added new notify client operation into ops.h in
3007 * Changed silc_server_packet_send_to_channel to send normal
3008 packets instead of just channel message packets. The function
3009 is now used to send the notify packets to channels. It is not
3010 used to send channel message packets anymore, as server never
3013 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3014 va_arg()s as it seems to require it nowadays. I guess, if SILC
3015 is compiled with older va_arg() the new code should work anyway.
3017 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Splitted core library. Core library (lib/silccore) includes
3020 now only SILC protocol specific core (and common) components.
3021 Created new utility library (lib/silcutil) that includes more
3022 generic purpose stuff. The stuff for util library was taken
3023 from the old core library. This was minor and easy split.
3025 * Created SILC Client Library (lib/silcclient) that includes
3026 implementation of the SILC client without user interface. This
3027 was major move from silc/ directory. The code has been changed
3028 so that it is transparent towards the user interface. The
3029 silc/ directory includes now the same user interface as before
3030 and it uses the new client library. Read lib/silcclient/README.
3031 Basicly, the client library performs everything else related
3032 to SILC except user interface handling. Also, configuration
3033 files are considered to be part of user interface and library
3034 does not handle them.
3036 This change also changed a lot of structures, function naming etc.
3037 Most important change was that SilcClientWindow object was
3038 renamed to SilcClientConnection in the client library. Created
3039 also new file lib/silcclient/ops.h. Also added new files
3040 silc/local_command.[ch] and silc/client_ops.[ch].
3042 All these changes were made to make it easier for user interface
3043 designers to create what ever user interface for the SILC client
3046 It is also expected that the server will be moved to lib
3047 directory as well and SILC Server Library will be created;
3048 sometimes in the future.
3050 * Removed Local commands from lib/silccore/silccommand.h as
3051 they are application specific and new client library does not
3052 handle any of those anymore.
3054 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3055 old client implementation in silc/.
3057 * Added support for callback functions in SILC_LOG_* macros.
3058 Application can now set its own callbacks that will be called
3059 instead of using the default functions that will always print
3060 the debug messages to stderr (or stdout). Also, debugging can
3061 now be disabled by setting silc_debug to FALSE and re-enabled by
3062 setting it to TRUE. Note, that logging will still work even
3063 if debugging is disabled.
3065 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3066 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3067 silc_log_reset_debug_callbacks.
3069 * To enable debugging in silc client one must give now -d
3070 option on command line.
3072 * Changed silc_schedule_init to automatically allocate task queues
3073 if they are not allocated before calling it.
3075 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Added GMP 3.1 into math library.
3079 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3082 a channel in SILC network. The packet is used by servers and
3083 routers to notify other routers that user has left a channel.
3084 This little feature was missing until now. Added the feature
3085 to protocol specification as well.
3087 Added functions: silc_server_send_remove_channel_user and
3088 silc_server_remove_channel_user into server.[ch].
3090 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3091 lib/silccore/silcpacket.h. However, they are not implemented
3094 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Fixed joining to a channel and sending channel messages
3097 between server and router. The channel message sending should
3098 now work inside a cell.
3100 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Fixed the private message sending between server and router.
3103 The private message sending should now work inside a cell.
3105 * Added silc_server_replace_id into server.[ch] to replace
3106 existing ID in the SILC network.
3108 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3109 and silc_idlist_replace_server_id into idlist.[ch] in server.
3111 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed the server to server connections. Server can again now
3114 connect to router. Router to router connections probably does
3117 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added dynamic protocol registering support. Now protocols can
3120 registered and unregistered on the fly. Patch by cras.
3122 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added lib/contrib directory to hold routines that some platforms
3125 don't have but are needed by SILC.
3127 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3128 into lin/contrib to provide getopt() and getopt_long() for
3129 those who don't have it.
3131 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Added AWAY command to client. When away message is set and
3134 client receives a private message packet the client automatically
3135 replies to the sender with the away message.
3137 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3138 bug seemed to be the cause of recent problems when compiling
3141 * Added version detection support to SKE protocol specification
3142 and added the new changes to the SKE implementation as well.
3143 There were other minor changes in the SKE protocol as well.
3145 Many changes in lib/silcske/silcske.[ch] and in
3146 lib/silcske/payload.[ch].
3148 * Added ^U functionality, clear input line. Patch from cras.
3150 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Mainly small bugfixes on core library. Fixed some debugging
3153 logging and buffer overflow in silclog.c.
3155 * Updated config.sub and config.guess on the distribution tree.
3157 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added command lagging support in server. Client may execute
3160 commands now only once in two seconds.
3162 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Optimized packet reception. MAC computation and checking is now
3165 also more optimized. A lot previously duplicated code is now
3166 used as generic by both client and server.
3168 * Fixed key pair generation in clientutil.c
3170 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Added into lib/silccore/silcbufutil.[ch] new function;
3173 silc_buffer_realloc.
3175 * Moved generic packet sending/encryption functions to
3176 lib/silccore/silcpacket.[ch] from client and server. Some
3177 rewriting of the functions.
3179 * Moved all generic packet reception/decryption functions to
3180 lib/silccore/silcpacket.[ch] from client and server. The
3181 packet processing is now much cleaner in both client and server.
3182 These were major changes in both client and server.
3184 * Created many common functions in server to do packet sending.
3185 Previously code were duplicated a lot, this has been removed
3188 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Rewrote major parts of the ID cache system. Don't know
3191 whether it is better now or not but at least the API is more
3194 * Major rewrite on ID cache stuff on client because of the ID
3195 cache API changes. Added idlist.c to client.
3197 * Also major rewrite on ID cache stuff on server as well.
3198 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3199 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3200 in hand, instead they are all put into the ID cache system now.
3201 All server_idlist_* routines uses ID cache now instead of
3202 traversing its own lists (those lists does not exist anymore).
3203 SilcIDList though still exists. Also, SilcXXXEntry's are
3206 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Finally made the SKE implementation compliant to the protocol
3209 specification. All mp integers are now binary encoded as
3210 opposed being HEX encoded.
3212 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3215 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3216 functions: silc_[encode/decode]_pem. Also added function
3217 silc_encode_pem_file to PEM encode with newlines ('\n') for
3220 * SILC public keys are now encoded either PEM or binary. Same
3221 option is for private keys as well. By default private keys
3222 are binary encoded and public keys PEM encoded. Silly HEX
3223 encoding were removed.
3225 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3226 function to create fingerprints.
3228 * Fixed a bug in SHA1; does not change the original data anymore.
3230 * Partly implemented INFO command on client and server side.
3231 Fixed CLEAR command. Changes to SERVER command; show current
3232 server(s) when giving command without arguments. Added
3233 VERSION command to client.
3235 * Added check to server that unregistered connections cannot
3236 execute commands (unless it is specificly allowed).
3238 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Fixed screen refresh.
3242 * Fixed channel joining bug from client. On some circumstances
3243 client tried to join to a channel it had already joined.
3245 * Added public key verification process into client's protocol.c.
3246 The client now verifies the public key from user and saves
3247 it into ~./silc/serverkeys/ directory.
3249 Added into: clientutil.[ch]: silc_client_verify_server_key.
3251 * Changed SKE protocol's silc_ske_initiator_finish function
3252 to accept callback function that verifies the received public
3253 key. Removed old silc_ske_verify_public_key function.
3255 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3258 silc_pkcs_private_key[_data]_set.
3260 * Made the password and public authentication more cleaner in
3261 server's protocol.c.
3263 * Removed historic and obsolete protocol `channel_auth' from
3264 both client and server.
3266 * Removed wrong way of sending command status messages from
3267 server to client in server's command.c. The old way violated
3268 protocol specification.
3270 Changes to silccore/silccommand.[ch]: removed
3271 silc_command_encode_status_payload -> not needed anymore,
3272 changed silc_command_encode_payload_va to accept extra
3273 argument on variable argument list. The argument type must
3274 now be provided to the function. Also, added new function:
3275 silc_command_encode_reply_payload_va which is same as
3276 normal command_encode_payload_va except command status type
3277 is provided as extra argument.
3279 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added ~./silc directory handling. The directory includes the
3282 public and private keys for the client.
3284 Added silc_client_check_silc_dir, silc_client_create_identifier
3285 and silc_client_load_keys.
3287 * Implemented SILC protocol compliant public key. Added public
3288 and private key saving to and loading from files.
3290 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3291 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3292 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3293 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3294 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3296 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3297 silc_pkcs_load_[public/private]_key.
3299 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Added silc_server_get_route (route.[ch]) to get connection
3302 data for the fastest route for given ID.
3304 * Implemented INVITE command on client and server. The command
3305 were re-defined in the SILC Protocol Specification and the
3306 implementation now complies with the specification.
3308 * Implemented PING command on client and server.
3310 * Implemented NAMES command on client and server. The server side
3311 supports currently only normal server not router server yet.
3312 Some changes to NAMES definition in SILC protocol specification.
3314 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Implemented LEAVE command on client and server.
3318 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3319 again. This change was made to the protocol as well. Server
3320 should not violate the protocol specification anymore.
3322 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3325 was tested. SOCKS4 was not but should work anyway.
