1 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed buffer overflow in silc_string_compare in the file
4 lib/silcutil/silcutil.c.
6 * Fixed double free in silc_server_command_leave in the file
9 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Fixed the version checking in the server. Affected file is
14 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Fixed the configuration data fetching when accepting new
17 connections in the server. Affected file silcd/server.c.
19 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Added `sender_entry' argument to the function
22 silc_server_packet_relay_to_channel so that we can check
23 whether some destination actually belongs to the same route
24 the sender belongs (ie, we must not resend the packet to the
25 sender). Affected file silcd/packet_send.[ch].
27 * Added `servername' field to the SilcClientEntry in the server
28 to hold the name of the server where client is from. Affected
29 file is silcd/idlist.h.
31 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Moved the channel message encrypting in the router betwen
34 router connections from silc_server_channel_message to the
35 silc_server_packet_relay_to_channel since we want to check
36 whether we have anybody channel before encrypting anything.
37 Affected files silcd/packet_[receive/send].c.
39 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Fixed the [AdminConnection] server config section to support
42 multiple entries. Affected file silcd/serverconfig.c.
44 * Added support into the server to check the validity of the
45 incoming connection before executing any KE or authentication
48 * The connection configuration is now saved to the KE and
49 connection auth protocol contexts and not fetched anymore in
50 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
52 * The local hosts listenning address and port is also resolved
53 now when starting the server. We want to have the socket object
54 to include the real address and port for the listener. Added
55 new function silc_net_check_local_by_sock into the files
56 lib/silcutil/silcnet.[ch].
58 * Fixed a broadcast bug in server -> do not broadcast if we
61 * Fixed a routing bug. Do not route broadcast packets ever.
62 Broadcast packets must be processed always and not routed since
63 they may be destined to some other host than yourself and thus
64 would get routed without no good reason. Affected file is
67 * Added function silc_server_config_is_primary_route to check
68 whether primary router connection has been configured (a router
69 configuration that we are initiating). If there is not, we
70 will assume that there is only two routers in the SILC network
71 and we will use the incoming router connection as our primary
72 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
74 * Changed the order of the broadcasting. Broadcast _after_ the
75 packet has been processed not before. Affected file is
78 * Fixed a [ClientConnection] parsing bug. The port was never
79 parsed correctly thus resulting to port 0. Affected file
82 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
83 argument and did not set the broadcast packet flag. Affected
84 file silcd/packet_send.c. Fixed same bug in the function
85 silc_server_send_notify as well.
87 * If we receive NEW_ID packet for our own ID in the server, ignore
90 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * Removed the nickname from the Private Message Payload.
95 Updated the code and the protocol specs.
97 * Updated protocol specs for submitting to the IETF.
99 * Tweaked the Random Number Generator a bit. Affected file
100 lib/silccrypt/silcrng.c. Exported a new function
101 silc_rng_[global]_add_noise which can be used to add more
104 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Do not parse packets with different timeout when protocol
107 is active -> may cause problem with rekey. Affected file
110 * When server receives signoff notify it must not create
111 new channel key if the client is on any channels since the
112 sender of the signoff notify will create it.
114 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Added printing of error messages during SKE protocol from the
117 failure packet sent by server during SKE. Affected file
120 * Removed the client's failure_callback handling with timeout
121 and handle it immediately when received.
123 * The SKE library returned wrong type in SUCCESS and FAILURE
124 packets. They must be 32 bit MSB not 16 bit MSB.
126 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Ok, rewrote the logic of the re-key and now it seems to work.
129 I tested it on high traffic with frequent re-keys without
130 problems. Added hmac_receive (and renamed hmac to hmac_send)
131 in SilcClientConnection in lib/silcclient/client.h and
132 in SilcIDListData in silcd/idlist.h. Also, removed the
133 SilcPacketParserContext's cipher and hmac fields as they are
134 not needed anymore and actually caused some problems when
135 the ciphers and hmac's changed underneath the packet parser.
137 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * If re-key protocol is active then process the incoming packets
140 synchronously since we must assure that icoming packets encrypted
141 with the old key is processed before the new keys is set to
142 use. This is true other packets than for REKEY packets.
143 Affected file silcd/server.c. The same was done to client library
144 as well, affected file lib/silcclient/client.c.
146 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed bug in client and server to accept the force send if
149 the packet is send from silc_[server/client]_packet_process
150 function. Otherwise the packets are never delivered, oops.
152 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Disable force sending of packets when REKEY protocol is active.
155 We must assure that no packet is sent directly when rekey is
156 performed. All packets must be sent through packet queue.
157 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
158 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
159 function is silc_[server/client]_packet_send_real to check
162 * Replaced the SIM paths from example config files to
163 /usr/local/modules. Also, make install creates now
164 /usr/local/silc/logs directory to hold all the SILC server
167 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
169 * Made the configure.in.pre work on Solaris. Patch by salo.
171 * Made all ciphers compatible with non-x86 machines. Defined
172 CBC mode macros into lib/silccrypt/ciphers_def.h.
174 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Fixed the make install.
178 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * When MAC computation fails the silc_packet_decrypt returned 0
181 even though it was supposed to return -1. Fixed this. The
182 affected file is lib/silccore/silcpacket.c.
184 * Do not replace the config files in /etc/silc (in make install)
185 if they already exist. Affected file ./Makefile.am.
187 * Do not send re-key packets immediately but through packet queue.
188 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
190 * Changed silc_net_check_host_by_sock to return FALSE if the
191 IP/DNS could not be resolved. Though, it returns the IP address
192 now even if it could not resolve it (but returns also FALSE).
193 Affected file lib/silcutil/silcnet.[ch].
195 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * Added silc_pkcs_decode_identifier to decode the public key's
198 identifier. Affected file lib/silccrypt/silpkcs.[ch].
199 Added also silc_pkcs_free_identifier. Added also new context
200 SilcPublicKeyIdentifier.
202 * Added -S option to the silc client. It is used to dump the
203 contents of the specified public key file.
205 * Changed the PKCS api to return the public key length when
206 setting the public key.
208 * Fixed a fatal bug in the public and private key file loading.
209 Affected file lib/silccrypt/silcpkcs.c.
211 * Execute the packet parsing for client with zero (0) timeout
212 if the protocol is active. Affected file silcd/server.c.
214 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Made the key generation options to the silcd program. Added
217 -C option, equivalent to client's option.
219 * Added new [ServerKeys] config section to the server. It
220 configures the server's public and private key.
222 * Defined generic Public Key Payload into the protocol
223 specification to send specific type of public keys and
226 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
227 public key or certificate.
229 * Implemented the GETKEY command to the server and to the
230 client library and on user interface.
232 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
234 * Made preliminary `make install' work.
236 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Added SilcServerRekey context into silcd/idlist.h.
240 * Added the PFS support as defined in the specification to the
241 SKE protocol. Affected files lib/silcske/*.c.
243 * Added `ske_group' field to the SilcServerRekey context to hold
244 the number of the SKE group that is used with PFS in re-key.
245 Affected file silcd/idlist.h.
247 * Added PFS re-key support to the server. Affected file is
250 * Added silc_protocol_cancel to cancel execution of the next
251 state of the protocol. Affected file is
252 lib/silccore/silcprotocol.[ch].
254 * Added the re-key support with and without PFS to the client
255 library. Re-key is performed once in an hour, by default.
257 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
258 Added silc_client_rekey_callback and silc_client_rekey_final.
259 Affected files are lib/silcclient/protocol.[ch] and
260 lib/silcclient/client.[ch].
262 * Removed the `hmac_key' and `hmac_key_len' fields from the
263 SilcClientConnection structure; not needed. Affected file is
264 lib/silcclient/client.h.
268 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Do not ask whether user wants to use the negotiated private key
271 for private messages, just use it. Affected file is
272 silc/local_command.c.
274 * Added `send_enc_key' and `enc_key_len' fields to the
275 SilcIDListData structure since they are needed in the re-key
276 phase. Affected file is silcd/idlist.[ch].
278 * Implemented the simple re-key protocol into the server.
279 Affected files silcd/server.c and silcd/protocol.[ch]. The
280 re-key will be performed once in an hour, by default.
282 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
283 Added silc_server_rekey, silc_server_rekey_callback and
284 silc_server_rekey_final.
286 * Removed Tunneled flag from the protocol. Updated the code
287 and the specifications.
289 * Adde `pfs' field to the SilcIDListData to indicate whether
290 the PFS is to be performed in the re-key. Affected file is
293 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
296 int64 of at least the xintXX size. If void * is less that 4
297 bytes uint32 * will be used. Defined bool as boolean.
299 * Changed _ALL_ unsigned long and unsigned int to uint32,
300 unsgined short to uint16 in the source tree.
302 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
303 not handle clients that has entry->data.registered == FALSE.
304 They are not in the network anymore. Affected file is
307 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Implemented the sending of the SERVER_SIGNOFF notify in the
310 server. Affected file is silcd/server.c.
312 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
313 Added also silc_notify_payload_encode_args into the
314 lib/silccore/silcnotify.[ch].
316 * Implemented ther SERVER_SIGNOFF notify handling in the server.
317 Affected file silcd/packet_receive.c.
319 * Implemented the SERVER_SIGNOFF notify handling in the client
320 library. Affected file lib/silcclient/client_notify.c. Also,
321 implemnted the printing of the SERVER_SIGNOFF info to the
322 application. Affected file silc/client_ops.c.
324 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
325 if the deleting was successful. Affected file silcd/idlist.[ch].
327 * Added support for public key authentication in the connection
328 authentication protocol in the client library. Affected file
329 lib/silcclient/protocol.c.
331 * Changed the server's silc_idlist_get_clients_by_* interface
332 to support already allocated array so that new entries may be
333 added to pre-allocated array. Affected file silcd/idlist.[ch].
334 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
337 * All command reply functions in the server now calls the
338 pending command callback even if error occured. This way the
339 error will be delivered to the client as well. Affected files
340 silcd/command.c and silcd/command_reply.c.
342 * Fixed INFO command to return local server's info if no server
343 was provided. Affected file lib/silcclient/command.c.
345 * Removed RESTART command for good. Updated the code and the
348 * Rewrote parts of the task system. It is a bit simpler now.
349 Removed unsued task priorities. The affected files are
350 lib/silcutil/silctask.[ch].
352 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Moved the USERS printing from the library to the application.
355 Affected files lib/silcclient/command.c and silc/client_ops.c.
357 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Added channel key re-key support. The re-key is perfomed
362 only by the router and is done once in an hour. Added `rekey'
363 field to the SilcChannelEntry in the server. Affected files
364 silcd/server.c and silcd/idlist.h.
366 * Added silc_task_unregister_by_context into the file
367 lib/silcutil/silctask.[ch].
369 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Added SILC_UMODE_GONE mode to indicate when the client is not
372 present in the SILC network. Added also support to the local
373 command AWAY that will set this mode. Added support of showing
374 "xxx is gone" in WHOIS command. The USERS command shows the
377 * Fixed setting server and router operator privileges in the
378 server's UMODE command. Affected file silcd/command.c.
380 * Merged the SKE KE1 and KE2 payloads into one payload. The
381 new KE payload is equivalent to the old KE2 payload.
383 Cleaned up the SKE Start Payload parsing. It now uses the
384 simple buffer unformatting to do the parsing. A lot faster
387 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
388 to the SKE that is used to indicate whether both of the SKE
389 parties should perform authentication. By default only the
390 responder performs authentication. By setting this flag also
391 the initiator must do authentication. By default it is unset
392 since in normal SKE case, client to server connection, only
393 the responder should do authentication. When doing SKE between
394 two clients both should perform authentication. Updated the
395 code and the protocol specs.
397 * A little fix to IDENTIFY command in the server. Search the
398 client first by hash not nickname. Affected file is
401 * Fixed the silc_client_close_connection to support closing
402 the client to client connections wihtout deleting too much
403 data. Affected file lib/silcclient/client.c.
405 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
406 are received if protocol used to be active but is not anymore
407 the application would crash due to NULL pointer dereference.
408 Affected files silcd/server.c and lib/silcclient/client.c.
410 * Added `hash' field to the SilcClientConnection to include
411 the hash function negotiated in the SKE protocol.
413 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
414 to set the channel founder authentication data. A client can
415 claim the founder rights later by providing the authentication
416 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
417 This way the channel founder can regain the channel founder
418 privileges even it is left the channel. This works only on
419 local server and the client must be connected to the same
420 server to be able to regain the founder rights. Updated the
421 protocol specs accordingly.
423 Added support to the CMODE command in the client to set the
424 founder auth data. Read the README to see how to set it.
426 Added support to the CUMODE command to claim the founder
427 rights. Read the README to see how to do it.
429 Added support for the founder authentication to the Channel
430 Entry in the server. Affected file silcd/idlist.h.
432 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
433 server's CMODE command. Affected file silcd/command.c.
435 * Added the following new functions into lib/silccore/silcauth.[ch]:
436 silc_auth_get_method and silc_auth_get_data.
438 * The server now saves the remote hosts public key to the
439 SilcIDListData pointer. Affected file silcd/protocol.c.
441 * The normal server now does not remove the channel entry from
442 the cache if the founder authentication data is set. It used
443 to remove it if the founder was the last one on the channel on
444 the server and left the channel. The auth data is saved and
445 if the channel is re-joined later the old entry is used with
446 the old auth data. Affected files silcd/command_reply.c and
449 * Removed the `pkcs' field from the SilcIDListData structure
450 in the server; it is not used. Affected file silcd/idlist.h.
452 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed packet processing on slow links. Partial packets were
455 never re-processed because the incoming data buffer was cleared
456 by the application. Application must not directly clear the
457 sock->inbuf, the packet processing routines handle it. Fixed
458 this in client library and in server.
460 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Fixed the WHOIS and IDENTIFY send reply function to really
463 check whether to send list or just one entry. Affected file
466 * Cleaned up the LEAVE command's channel key distribution. The
467 affected file silcd/command.c.
469 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
470 can enforce the channel mode as well. In that case the ID
471 includes the ID of the server. The code now enforces the
472 mode change if the router have different mode than the server.
474 * The notify client operation with CMODE_CHANGE notify can now
475 return NULL client_entry pointer if the CMODE was not changed
476 by client. Application must check for this.
478 * Added <Server ID> argument to INFO command to support server
479 info fetching by Server ID.
481 * Added silc_server_announce_get_channel_users to get assembled
482 packets of channel users of the specified channel. Affected
483 file silcd/server.[ch].
485 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
486 was freed underneath the ID Cache.
488 * Re-announce clients when the server received CHANNEL_CHANGE
489 notify from the router. Affected file silcd/packet_send.c.
491 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
494 crashed since it did not handle the fact that there is no cipher
495 called "3" and didn't check the error condition. Now fixed.
497 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
498 flag. It can be used to send message requests.
500 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Implemented the RESTART command in the client.
504 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
505 notice type messages. Added notice printing to the user
508 * The channel keys are not re-generated if the channel's mode
509 is PRIVKEY, ie private key on the channel exists. Affected
510 files silcd/server.c and silcd/command.c.
512 * Fixed a little bug in channel message delivery when channel
513 private keys are set in the server. Affected file is
516 * Changed the setting on channel->on_channel = TRUE from the
517 silc_client_save_channel_key to the JOIN command reply. The
518 key payload is not received if the private channel key is set.
519 Affected file lib/silcclient/command_reply.c and the
520 lib/silcclient/client_channel.c.
522 * When the CMODE_CHANGE notify is sent and the channel private
523 key mode is removed the channel key must be re-generated in
524 other cells as well. Added this support for the router in the
525 silcd/packet_receive.c.
527 * Added new local command NOTICE to send notice message on
528 channel. Affected file silc/local_command.[ch].
530 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Added new local command ME to the client. It is used to send
533 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
534 some action. Affected file silc/local_command.[ch].
536 * Changed channel_message and private_message client operations
537 to deliver the message flags to the application. Added also
538 the `flags' arguments to the silc_client_send_channel_message
539 and silc_client_send_private_message functions. Affected file
542 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Redefined the Private Message Payload to support private message
545 keys and to support the new private message flags. Updated
546 the protocol specs. Flags makes it possible to have for example
549 * Added new type SilcPrivateMessagePayload and defined an API
550 for it in the lib/silcclient/silcprivate.[ch].
552 * Tested private message private keys successfully. Tested the
553 private message key set, unset and list commands with the new
556 * Redefined the Channel Message Payload to include the channel
557 message flags (equal with private message flags) to support
558 for example CTCP style messages.
560 * Defined some of the message (for channel and private message)
561 flags. Updated the protocol specs and added the flags to the
562 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
564 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Added SilcKeyAgreementStatus type to the key agreement routines
567 to indicate the current status and error if one occured.
568 The status types are defined in the lib/silcclient/silcapi.h.
570 * Added new local command KEY that is used to set and unset private
571 keys for channels, set and unset private keys for private messages
572 with remote clients and to send key agreement requests and
573 negotiate the key agreement protocol with remote client. The
574 key agreement is supported only to negotiate private message keys,
575 it currently cannot be used to negotiate private keys for channels,
576 as it is not convenient for that purpose.
578 * Fixed a minor pending callback setting bug in the function
579 silc_client_get_client_by_id_resolve, now the function works.
580 Affected file lib/silcclient/idlist.c.
582 * Added function silc_net_get_local_port to get local bound
583 port by socket. Added to lib/silcutil/silcnet.[ch].
585 * Added `sockets' and `sockets_count' fields to the SilcClient
586 object. They hold the sockets of the listenning sockets in
587 the client. Listenning sockets may be for example the key
588 agreement server. Affected file lib/silcclient/client.[ch].
589 Added functions the silc_client_add_socket and the
590 silc_client_del_socket. They are exported to the application
593 * Added ~./silc/clientkeys to support other client's public keys.
595 * Renamed verify_server_key client operation to verify_public_key
596 and added one argument to indicate the type of the connection
597 (server, client etc.).
599 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Added silc_server_connection_auth_request to handle the
602 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
603 silcd/packet_receive.[ch].
605 * Added silc_server_send_connection_auth_request into the
606 silcd/packet_send.c to send the connection auth request packet.
608 * Cleaned up the silcd/protocol.c a bit and fixed some memory
611 * Fixed the public key authentication in responder side in the
612 server. The `auth_data' pointer includes the SilcPublicKey
613 not the path to the public key. Affected file silcd/protocol.c.
615 * Implemented the public key authentication in the initiator side
616 in the server. Affected file silcd/protocol.c.
618 * Removed the [RedirectClient] config section from the server
619 configuration. Is not needed and I don't want to implement it.
621 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Cleaned up the CMODE command in the server. It now works
624 correctly and supports all the modes defined in the protocol.
625 Affected file is silcd/command.c.
627 * Added `hmac_name' field to the SilcChannelEntry in the server
628 to hold the default HMAC of the channel. It can be set when
629 creating the channel (with JOIN command). Affected files
632 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
633 type to indicate the change of the current cipher and hmac
634 on the channel. Client can safely ignore the <cipher> argument
635 (if it chooses to do so) since the CHANNEL_KEY packet will
636 force the channel key change anyway. The <hmac> argument is
637 important since the client is responsible of setting the new
638 HMAC and the hmac key into use.
640 * Fixed the CMODE command in the client library as well.
642 * Tested CMODE command in router environment successfully.
644 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Show the version of the remote client (or server) when connecting
647 to the server. It is logged to the log file. Affected file
650 * Fixed the KILLED notify handling in the client library. The
651 client must be removed from all channels when receiving the
654 Also, do not remove the client entry when giving the KILL
655 command but when the KILLED notify is received.
657 * Removed silc_idlist_find_client_by_nickname from the server.
658 Not needed anymore. Affected files silcd/idlist.[ch].
660 * Implemented the CHANNEL_CHANGE notify type handling to the
661 server. Affected file silcd/server.c.
665 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * Added silc_server_send_notify_invite to send the INVITE
668 notify between routers.
670 * Implemented the INVITE command correctly to the server.
672 * Implemented the INVITE notify type handling in the server.
674 * Implemented the INVITE command to the client library and on the
677 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Added function silc_server_get_client_resolve to find the
680 client entry by ID from all ID lists and then resolve it
681 (using WHOIS) if it cannot be found. Affected file is
684 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Implemented the BAN command to the client library.
688 * The JOIN command in the server now checks the invite list
691 * Changed the silc_command_reply_payload_encode_va and the
692 silc_command_payload_encode_va to support that if argument is
693 NULL it ignores and checks the next argument. Affected file
694 lib/silccore/silccommand.c.
696 * Added silc_server_send_notify_ban to send the BAN notify
697 type between routers.
699 * Chaned the silc_notify_payload_encode to support that if
700 argument is NULL it ignores and checks the next argument.
701 Affected file lib/silccore/silcnotify.c.
703 * Tested ban lists in router environment successfully.
705 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Implemented BAN command to the server, in silcd/command.[ch].
709 * Removed the BAN and INVITE_LIST modes from the CMODE command
712 * Added function silc_string_match to regex match two strings.
713 Affected files lib/silcutil/silcutil.[ch].
715 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Redefined parts of the SilcChannelEntry in the server to support
718 the new ban and invite lists.
720 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Redefined the INVITE command. The same command can be used to
723 invite individuals to the channel but also to manage the invite
724 list of the channel (to add to and remove from the invite list).
725 Updated the protocol specs.
727 * Added new command SILC_COMMAND_BAN that can be used to manage
728 the ban list of the channel. Updated the protocol specs.
730 * Removed the channel modes: the SILC_CMODE_BAN and the
731 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
732 in the CMODE command. The equivalent features are now available
733 using INVITE and BAN commands. Updated the protocol specs.
735 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
736 in the network about change in the current ban list. The notify
737 type is not used by the client.
739 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
740 support the invite lists.
742 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Added new function silc_string_regexify that converts string
745 including wildcard characters into regex string that can
746 be used by the GNU regex library. Added into the file
747 lib/silcutil/silcutil.[ch].
749 Added silc_string_regex_combine to combine to regex strings
750 into one so that they can be used as one regex string by
751 the GNU regex library. Added into the file
752 lib/silcutil/silcutil.[ch].
754 Added silc_string_regex_match to match two strings. It returns
755 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
757 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Imported GNU regex to the soruce tree into lib/contrib.
760 Fixed some compiler warning from the regex.c.
762 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Fixed MOTD command in the server to work in router environment.
766 * Fixed the MOTD command in the client library to support
767 the server argument in the command.
769 * Added `nickname_len' argument to the silc_idlist_add_client
770 in the server, as the `nickname' argument may be binary data
773 * Added silc_idlist_get_channels to return all channels from
776 * Implemented LIST command to the server. Affected file is
779 * Implemented the LIST command to the client library and on the
782 * Added [<user count>] argument to the LIST command reply.
783 With private channels the user count is not shown.
785 * Updated TODO and README.
787 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * The client entry's data.registered must be TRUE even with
790 global client entry on global client list. The data.registered
791 is used to check whether the client is anymore in the network,
792 for example with WHOWAS command so it must be valid.
794 * Fixed the WHOWAS command in the server. It now actually works
795 in router environment. Added function into silcd/command_reply.c
796 silc_server_command_reply_whowas_save.
798 * Added silc_idlist_purge function to the silcd/idlist.c
799 to periodically purge the ID Cache.
801 * Fixed INFO command in the server. It works now in router
802 environment. Added <server name> argument to the INFO command
803 reply. Updated the protocol specs.
805 * Fixed minor bug in silc_idcache_purge to not purge if the
806 expire value is zero.
808 * Fixed various bugs in WHOIS and IDENTIFY command handling as
809 they were buggy because of the WHOWAS information.
811 * Fixed local command MSG to handle the async resolving of
812 the remote client properly. It used to fail the first MSG.
813 Affected file silc/local_command.c.
815 * Added `data_len' field to SilcIDCache context.
817 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Update TODO. Todo in commands in the server.
821 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
824 used by routers as broadcast packet to inform other routers
825 about the changed user mode.
827 Implemented the notify handling in the server. Affected file is
828 silcd/packet_receive.c. Added the function
829 silc_server_send_notify_umode to the silcd/packet_send.[ch].
831 * Added new generic Channel Payload and deprecated the New Channel
832 Payload. The New Channel Payload is now the generic Channel
835 * Added new argument `mode' to the silc_server_send_new_channel
836 as it is required in the Channel Payload now.
838 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
839 and created a new and real SilChannelPayload to represent the
840 new generic Channel Payload. Implemented the encode/decode
841 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
843 * Added silc_server_get_client_channel_list to return the list
844 of channels the client has joined for WHOIS command reply.
845 Affected file silcd/server.[ch].
847 * Implemented the channel list sending in the WHOIS command reply
848 in server and in the client.
850 Implemented the channel list displaying on the user interface
851 as well. Affected file silc/client_ops.c.
853 * Added silc_channel_payload_parse_list to parse list of Channel
854 Payloads. It returns SilcDList list of SilcChannelPayloads.
855 Client for example can use this function to parse the list of
856 channels it receives in the WHOIS command reply. The caller
857 must free the list by calling silc_channel_payload_list_free.
858 Affected files lib/silccore/silcchannel.[ch].
860 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Added one new argument <user mode> to the WHOIS command reply
863 to return the mode of the user in SILC. Updated the protocol
866 Implemented it to the server and client.
868 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Fixed the mode printing on the user interface on joining.
871 Affected file silc/client_ops.c.
873 * Implemented the UMODE command and user modes in general to the
874 client library and to the user interface.
876 * Implemented the UMODE command to the server.
878 * The server now sends UNKNOWN_COMMAND error status if client sends
879 unknown command. Affected file silcd/command.c.
881 * All server commands now handle the command identifier the right
882 way when sending the command reply to the client. The client can
883 use to identify the command replies with the identifier.
885 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Added silc_server_get_client_route to resolve the route to
888 the client indicated by the client ID. Affected file is
891 * Added silc_server_relay_packet as general function to relay
892 packet to arbitrary destination. This deprecates functions
893 like _send_private_message_key, _relay_notify etc. Affected
894 file is silcd/packet_send.[ch].
896 Removed silc_server_send_key_agreement,
897 silc_server_send_private_message_key and
898 silc_server_packet_relay_notify functions from the file
899 silcd/packet_send.[ch].
903 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
904 server. Affected file silcd/packet_receive.[ch].
906 * Implemented the KILL command to the client. Implemented the
907 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
908 Affected files lib/silcclient/command[_reply].c and
909 lib/silcclient/client_notify.c. Implemented the KILL notify
910 printing in the user inteface.
912 * Fixed a lot silc_parse_nick memory leaks from the client
913 library in the file lib/silcclient/command.c.
915 * Changed the silc_server_send_notify_on_channels's `sender'
916 argument from SilcSocketConnection to SilcClientEntry to
917 check the sender as entry and not as connection object and not
918 to send to the client provided as argument. The affected file
919 is silcd/packet_send.[ch].
921 * The notify packets that are destined directly to the client used
922 to not to be processed by the server. Now changed that and the
923 server processes all notify packets. After relaying the packet
924 to the client the notify packet is processed in the server.
926 * The silc_server_free_client_data now checks whether there is
927 pending outgoing traffic for the client and purges the data to
928 the network before removing the client entry.
930 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
933 an client is killed from the SILC Network. Updated the protocol
936 Added new function silc_server_send_notify_killed to the
937 silcd/packet_send.[ch].
939 * Added function silc_server_packet_relay_notify to relay notify
940 packets that are destined directly to a client. In this case
941 the server does not process the notify packets but merely relays
942 it to the client. Affected file silcd/packet_send.[ch].
944 Added also silc_server_packet_process_relay_notify to check
945 whereto relay the notify. Affected file is
946 silcd/packet_receive.[ch].
948 * Implemented the KILL command to the server.
952 * Added the backup schema desgined last fall to the protocol
953 specs for everyone to see. The specification is in the
954 *-spec-xx.txt draft and the packet type definitions for the
955 backup routers is in *-pp-xx.txt draft. Thusly, added also
956 new packet type SILC_PACKET_CELL_ROUTERS.
958 * A big security problem in the implementation discovered. The
959 signoff of an client did not cause new channel key generation
960 which it of course should've done. The channel keys must be
961 always re-generated when client leaves (or signoffs) the channel.
962 The silc_server_remove_from_channels funtion now handles
963 the channel key re-generation.
965 * Added `sender' argument to the silc_server_send_notify_on_channels
966 to not to send the client provided as argument. Affected file
967 silcd/packet_send.[ch].
969 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Implemented OPER and SILCOPER commands into the server and
974 * Added silc_auth_verify and silc_auth_verify_data to verify
975 the authentication directly from the authentication payload.
976 It supports verifying both passphrase and public key based
977 authentication. Affected file lib/silccore/silcauth.[ch].
979 * Added `hash' field to the SilcIDListData structure. It is the
980 hash negotiated in the SKE protocol. Affected file is
983 * Slight redesigning of the SilcAuthPayload handling routines.
984 Do not send SilcPKCS but SilcPublicKey as argument.
986 * Implemented the public key authentication support to the
987 serverconfig. The public key is loaded from the provided path
988 and saved as authentication data to void * pointer. Thus,
989 changed the unsigned char *auth_data to void *auth_data;
991 * Fixed SHUTDOWN command to send the reply before the server
992 is shutdown. :) Affected file silcd/command.c.
994 * Fixed fatal bug in CONNECT command. The hostname was invalid
995 memory and server crashed. Affected file silcd/command.c.
997 * Fixed fatal bug in CLOSE command. The server_entry became
998 invalid but was referenced later in the command. Affected file
1001 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Fixed fatal bug in failure packet handling. Server ignored
1004 the failure and thus crashed when it came.
1008 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1011 that the command may be executed only once in (about) 2 seconds.
1012 The old SILC_CF_LAG flag is same but allows command bursts up
1013 to five before limiting.
1015 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1016 server code. Various commands now includes the CF_LAG_STRICT
1017 flag to disallow any kind of miss-use of the command.
1019 * Fixed the silc_buffer_unformat to not to allocate any data
1020 if the length of the data is zero. It used to allocate the
1021 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1023 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Changed the format of AdminConnection configuration section
1026 in the server. Added username of the admin to the format.
1027 Affected files silcd/serverconfig.[ch].
1029 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1030 to return admin configuration data by host, username and/or
1033 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Implemented WHOWAS command to the server. Added the functions:
1037 silc_server_command_whowas_parse,
1038 silc_server_command_whowas_send_reply,
1039 silc_server_command_whowas_from_client and
1040 silc_server_command_whowas_from_server
1042 * Added <Client ID> argument to the WHOWAS command reply. Updated
1043 the protocol specs accordingly.
1045 * Implemented WHOWAS command and command_reply to the client
1048 Implemented the WHOWAS printing on the user interface.
1050 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Added new argument to the WHOWAS command reply, the real name.
1053 It is an optional argument. Updated the protocol specs.
1055 * Added SilcIDCacheDestructor callback that is registered when
1056 the SilcIDCache is allocated. The callback is called when
1057 an cache entry in the ID Cache expires, or is purged from the
1058 cache. Added into lib/silccore/idcache.[ch].
1060 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1061 to destruct the client entries when the cache entry expires.
1062 Other ID Cache's in server and in the client library ignores
1065 * If the ID Cache entry's `expire' field is zero then the entry
1066 never expires. Added boolean `expire' argument to the
1067 silc_idcache_add function in the lib/silccore/idcache.[ch].
1068 If it is TRUE the default expiry value is used.
1070 * Added silc_server_free_client_data_timeout that is registered
1071 when client disconnects. By default for 5 minutes we preserve
1072 the client entry for history - for WHOWAS command.
1074 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Added support to the server to enforce that commands are not
1077 executed more than once in 2 seconds. If server receives
1078 commands from client more frequently, timeout is registered
1079 to process the commands. Affected file silcd/command.c.
1080 Added new function silc_server_command_process_timeout.
1082 * Changed NICK_NOTIFY handling in client library to check that
1083 if the client's nickname was changed, so there is no need to
1084 resolve anything from the server.
1086 * Removed error printing from the WHOIS and IDENTIFY commands.
1087 If error occurs then it is ignored silently in the client library.
1088 The application, however, may map the received error to
1089 human readable error string. The application currently maps
1090 the NO_SUCH_NICKNAME error to string.
1092 * Made the command status message public to the application. Moved
1093 them from lib/silcclient/command_reply.c to
1094 lib/silcclient/command_reply.h. The application can map the
1095 received command status to the string with the
1096 silc_client_command_status_message function.
1098 * Added check to the server to check that client's ID is same
1099 as the Source ID in the packet the client sent. They must
1102 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added dist-bzip hook to the Makefile.am to make bzip2
1105 compressed distributions.
1107 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Server now enforces the maximum length for the nickname and
1110 the channel as protocol specification dictates. 128 bytes for
1111 nickname and 256 bytes for channel name.
1113 * Moved the WHOIS printing to the application. The client libary
1114 does not print out the WHOIS information anymore, the application
1115 must do it. Renamed silc_client_command_reply_whois_print to
1116 the silc_client_command_reply_whois_save.
1118 The client's idle time is also sent to the application now, and
1119 the idle is shown on screen.
1121 * Added silc_client_command_reply_identify_save to save the
1122 received IDENTIFY entries.
1124 * Do not check for channel private keys in message sending and
1125 reception if the channel does not have the PRIVKEY mode set.
1126 Affected file lib/silclient/client_channel.c.
1128 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1131 just surfaced after chaning the JOIN procedure.
1133 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added silc_client_get_clients_by_list to get client entries
1136 from Client ID list, that is returned for example by JOIN
1137 and USERS command replies. The application should use this
1138 function for example when JOIN command reply is received to
1139 resolve the clients already on the channel (library does not
1140 do that anymore as USERS command reply is not used in the JOIN
1141 procedure anymore). Affected files lib/silcclient/silcapi.h and
1142 lib/silcclient/idlist.c.
1144 * JOIN command reply and USERS command reply returns now SilcBuffer
1145 pointers instead of unsigned char pointers when returning
1146 the client list and mode list.
1148 * Added <Client ID> argument to the JOIN command reply, mainly
1149 for the server to identify for which client the command was
1150 originally sent. Updated protocol specs accordingly.
1152 * Added SilcDlist private_key pointer to the SilcChannelEntry
1153 in the client to support the channel private keys. Affected
1154 file is lib/silcclient/idlist.h.
1156 * Added SilcChannelPrivateKey argument to the function
1157 silc_client_send_channel_message so that application can choose
1158 to use specific private ke if it wants to. If it is not provided,
1159 the normal channel key is used, unless private keys are set.
1160 In this case the first (key that was added first) is used
1161 as the encryption key.
1163 * Implemented the support for channel private key handling.
1164 Implemented the following functions:
1166 silc_client_add_channel_private_key,
1167 silc_client_del_channel_private_keys,
1168 silc_client_del_channel_private_key,
1169 silc_client_list_channel_private_keys and
1170 silc_client_free_channel_private_keys
1172 Affected file lib/silcclient/client_channel.c.
1174 * Added the support for the private keys in the channel message
1175 sending and encryption and in the message reception and
1176 decryption. Affected funtions are
1177 silc_client_send_channel_message and silc_client_channel_message.
1179 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Added SKE's key verify callback to the client library's
1182 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1184 * Removed the statement that server (or router) must send USERS
1185 command reply when joining to the channel so that the client
1186 knows who are on the channel. Instead, the client list and
1187 client's mode list is now sent in the JOIN command reply to the
1188 client who joined channel. This is better solution.
1190 * Added function silc_server_get_users_on_channel and function
1191 silc_server_save_users_on_channel to the silcd/server.[ch].
1193 * Removed function silc_server_command_send_users from the
1196 * Do not show topic on the client library anymore. The topic is
1197 sent in the command reply notify to the application and the
1198 application must show the topic now.
1200 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Added client searching by nickname hash into the IDENTIFY and
1203 WHOIS commands in the server as they were clearly missing from
1204 them. Affected file is silcd/command.c.
1206 * Fixed a bug in private message receiving in the client library.
1207 The remote ID was freed and it wasn't supposed, now it is
1210 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Minor fix to the channel payload; allocate the data area, as it
1213 needs to be of specific length.
1215 * If the key agreement port is zero then the operating
1216 system will define the bound port. Affected files are
1217 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1219 * Added new function silc_channel_payload_decrypt into the file
1220 lib/silccore/silcchannel.[ch].
1222 * Moved the channel message etc, check from silc_packet_decrypt
1223 to applications. The library calls now a generic
1224 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1225 when the packet is either normal or special. This was done to
1226 allow more wide range of checking that was not allowed when
1227 the code was in library. Now applications can do virtually any
1228 checks to the packet and return to the library the decision how
1229 the packet should be processed. Affected files are
1230 lib/silccore/silcpacket.[ch].
1232 Added silc_server_packet_decrypt_check to the server and
1233 silc_client_packet_decrypt_check to the client library.
1235 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1236 to send with specified source and destination information.
1238 * Channel message delivery between routers was broken after the
1239 channel key distribution was fixed earlier. The channel key
1240 was used be to distributed to other routers as well which is not
1241 allowed by the protocol. Now this is fixed and channel keys
1242 really are cell specific and the channel message delivery between
1243 routers comply with the protocol specification.
1245 * Fixed various commands in server to check also the global list
1246 for the channel entry and not just the local list. The affected
1247 file silcd/command.c.
1249 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1251 * Added assert()s to buffer formatting and unformatting routines
1252 to assert (if --enable-debug) when error occurs. Affected
1253 file: lib/silcutil/silcbuffmt.c.
1255 * Changed to auto-reconnect to check whether the remote host is
1256 router and register the re-connect timeout if it is. It used
1257 to check that whether we are normal server, but router must do
1258 auto-reconnect with another router as well. Affected file
1261 * Removed the [<key len>] option from CMODE command as the cipher
1262 name decides the key length, nowadays. See the defined ciphers
1263 from the protocol specification.
1265 * Added [<hmac>] option to the CMODE command to define the HMAC
1266 for the channel. Added SILC_CMODE_HMAC channel mode.
1268 * Added [<hmac>] option for the JOIN command so that user can
1269 select which HMAC is used to compute the MACs of the channel
1272 * Added Hmac field to the Channel Message Payload. The integrity
1273 of plaintext channel messages are now protected by computing
1274 MAC of the message and attaching the MAC to the payload. The
1275 MAC is encrypted. Now, it is clear that this causes some
1276 overhead to the size of the packet but rationale for this is that
1277 now the receiver can verify whether the channel message decrypted
1278 correctly and also when private keys are set for the channel the
1279 receiver can decrypt the packet with several keys and check from
1280 the MAC which key decrypted the message correctly.
1282 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1283 lib/silccrypt/silccipher.[ch].
1285 * Added silc_hash_len to return the digest length into the
1286 lib/silcrypt/silchash.[ch].
1288 * Rewrote parts of Silc Channel Payload interface in the
1289 lib/silccore/silcchannel.[ch]. The encode function now also
1290 encrypts the packet and parse function decrypts it.
1292 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Fixed a minor formatting bug in the SKE's key material processing.
1295 It actually might have processed the keys wrong way resulting
1298 * Redefined the mandatory HMAC algorithms and added new algorithms.
1299 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1300 and hmac-md5 truncated to 96 bits. The mandatory is now
1301 hmac-sha1-96. Rest are optional (including the one that used
1302 to be mandatory). Rationale for this is that the truncated HMAC
1303 length is sufficient from security point of view and can actually
1304 make the attack against the HMAC harder. Also, the truncated
1305 HMAC causes less overhead to the packets. See the RFC2104 for
1308 * Added new [hmac] configuration section. The SKE used to use
1309 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1310 is of course wrong. The official names that must be proposed in
1311 the SKE are the ones defined in the protocol specification
1312 (hmac-sha1-96 for example). The user can configure any hmac
1313 using any hash function configured in the [hash] section. At
1314 least, the mandatory must be configured.
1316 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1318 * Added HMAC list to the SKE proposal list. It has now both
1319 hash algorithm list and HMAC list. This makes the protocol
1320 incompatible with previous versions. The SKE now seems to work
1321 the way it is supposed to work, for the first time actually.
1323 * Defined plain Hash algorithms to the protocol specification.
1326 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Implemented support for key agreement packets into the server.
1329 Added functions silc_server_key_agreement and
1330 silc_server_send_key_agreement. Other than these functions,
1331 server has nothing to do with this packet.
1333 * Added support for private message key packets into the server.
1334 Added functions silc_server_private_message_key and
1335 silc_server_send_private_message_key.
1339 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1340 called in the protocol's final callback instead in the END
1341 protocol state. This makes a little more sense and in the same
1342 time in client we can use the same protocol routines for normal
1343 key exchange and to key agreement packet handling as well.
1345 * Added to both client's and server's KE protocol context the
1346 SilcSKEKeyMaterial pointer to save the key material. We will
1347 bring the key material to the protocol's final callback by doing
1348 this. The final callback must free the key material.
1350 * Added SKE's packet_send callback into client's KE protocol
1351 context so that the caller can choose what packet sending function
1352 is used. This way we can use different packet sending when
1353 doing normal SKE when doing key agreement packet handling (in
1354 the key agreement packet handling we do not want to encrypt
1357 * Implemented the responder side of the key agreement routines
1358 in the client. The client can now bind to specified port and
1359 accept incoming key negotiation. The key material is passed
1360 to the application after the protocol is over.
1362 * Implemented the processing of incoming Key Agreement packet
1363 in the client. Added function silc_client_key_agreement to
1366 * Implemented the intiator side of the key agreement routines
1367 in the client. The client can now initiate key agreement with
1368 another remote client. The key material is passed to the
1369 application after the protocol is over.
1371 * Created client_keyagr.c to include all the key agreement
1374 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1375 SILC_TASK_CALLBACK except that it is not static.
1377 * Created client_notify.c and moved the Notify packet handling
1378 from the client.[ch] into that file.
1380 * Created client_prvmsg.c and moved all private message and
1381 private message key routines from the client.[ch] into that file.
1383 * Create client_channel.c and moved all channel message and
1384 channel private key routines from the client.[ch] into that file.
1386 * Changed silc_client_get_client_by_id_resolve to resolve with
1387 WHOIS command instead of IDENTIFY command, in the file
1388 lib/silclient/idlist.c.
1390 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Implemented the SKE's responder side to the Client library.
1394 * When FAILURE is received to the protocol do not trust it
1395 blindly. Register a timeout to wait whether the remote closes
1396 the connection as it should do it, only after that process the
1397 actual failure. This was changed to both client and server.
1399 * Added client_internal.h to include some of the structures
1400 there instead of client.h in lib/silcclient/.
1402 * Added function silc_task_unregister_by_callback to unregister
1403 timeouts by the callback function.
1405 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Some "Incomplete WHOIS info" errors has been appearing on the
1408 log files. Took away the entry->userinfo check from WHOIS
1409 reply sending. The entry->userinfo is now " " if client did not
1410 provide one. I thought this was fixed earlier but something
1411 is wrong still. Let's see if the error still appears.
1413 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Fixed a minor bug in the login when the channel key is
1416 re-generated in the server. It used to generate the key in
1417 wrong order and thus caused problems in the channel traffic.
1419 * Fixed a minor bug in channel key distsribution after
1420 KICK command. The key was not sent to the router even though
1423 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added silc_ske_process_key_material_data as generic routine
1426 to process any key material as the SILC protocol dictates. The
1427 function is used by the actual SKE library but can be used by
1428 applications as well. This relates to the private message keys
1429 and the channel private keys since they must be processed the
1430 same way the normal SILC session keys. The protocol dictates
1431 this. Affected files: lib/silcske/silcske.[ch].
1433 Added also silc_ske_free_key_material to free the
1434 SilcSKEKeyMaterial structure.
1436 * Defined silc_cipher_set_key function to set the key for
1437 cipher without using the object's method function. The affected
1438 files: lib/silccrypt/silccipher.[ch].
1440 * Implemented silc silc_client_add_private_message_key,
1441 silc_client_add_private_message_key_ske,
1442 silc_client_del_private_message_key,
1443 silc_client_list_private_message_keys and
1444 silc_client_free_private_message_keys functions in the
1447 Added functions silc_client_send_private_message_key to send
1448 the Private Message Key payload and silc_client_private_message_key
1449 to handle incoming Private Message Key payload.
1451 * Added Cipher field to the Private Message Key payload to set
1452 the cipher to be used. If ignored, the default cipher defined
1453 in the SILC protocol (aes-256-cbc) is used.
1455 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1457 * Removed lib/silcclient/ops.h file.
1459 Redefined parts of the SILC Client Library API. Created new
1460 file silcapi.h that deprecates the ops.h file and defines the
1461 published Client Library API. Defined also private message key
1462 API and channel private key API into the file.
1464 This is the file that the application must include from the
1465 SILC Client Library. Other files need not be included by
1466 the application anymore.
1468 * Added new key_agreement client operation callback and also
1469 defined the Key Agreement library API for the application.
1471 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1474 is used by clients to request key negotiation between another
1475 client in the SILC network. If the negotiation is started it
1476 is performed using the SKE protocol. The result of the
1477 negotiation, the secret key material, can be used for example
1478 as private message key.
1480 Implemented the Key Agreement payload into the files
1481 lib/silccore/silauth.[ch].
1483 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Redefined ciphers for the SILC protocol. Added some new ciphers
1486 and defined the key lengths for the algorithms. Changed the
1487 code accordingly. The default key length is now 256 bits.
1489 * Fixed SKE key distribution function silc_ske_process_key_material
1490 when the key length is more than 128 bits. The default key
1491 length in SILC is now 256 bits.
1493 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1494 to indicate unsupported algorithm.
1496 * Renamed rijndael.c to aes.c and all functions as well.
1498 * Fixed a long standing channel key setting bug in client library.
1499 Weird that it has never surfaced before.
1501 * Fixed bug in channel deletion. If the entire channel is removed
1502 then it must also delete the references of the channel entry
1503 from the client's channel list as the client's channel entry and
1504 the channel's client entry share same memory.
1506 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Implemented CONNECT and SHUTDOWN commands in the client.
1510 * Implemented CLOSE command to the client.
1512 * Added the function silc_idlist_find_server_by_name into the
1513 files silcd/idlist.[ch].
1515 Added the function silc_idlist_find_server_by_conn into the
1516 files silcd/idlist.[ch].
1518 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * DIE command was renamed to SHUTDOWN. Updated the both code
1523 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1524 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1526 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1529 * Added function silc_server_create_connection function to create
1530 connection to remote router. My server implementation actually
1531 does not allow router to connect to normal server (it expects
1532 that normal server always initiates the connection to the router)
1533 so the CONNECT command is only good for connecting to another
1536 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1539 or some other client was kicked from the channel.
1541 Implemented the handling of the notify type to both client
1544 Implemented silc_server_send_notify_kicked to send the KICKED
1545 notify. It is used to send it to the server's primary router.
1547 * Implemented the KICK command into server and client.
1549 * Added `query' argument to the silc_idlist_get_client function
1550 to indicate whether to query the client from server or not if
1553 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1554 to indicate that the client is not channel founder.
1558 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Removed the rng context from SilcPacketContext structure and
1561 changed that the packet routine uses the Global RNG API.
1563 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Added support for quit message that client can "leave" on the
1566 channel when it quits the SILC. It is ditributed inside the
1567 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1569 Added silc_server_free_client_data that will take the
1570 signoff message as argument.
1572 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1574 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Updated parts of the protocol specification to keep it up
1579 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1582 payloads in one packet.
1584 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1585 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1586 use now the new List flag.
1588 * Also deprecated the following packet types: REPLACE_ID,
1589 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1591 * Added list support for Notify packet in server.
1593 * Added silc_server_send_notify_channel_change to send the
1594 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1595 the silc_server_send_replace_id.
1597 * Added silc_server_send_notify_nick_change to send the
1598 NICK_CHANGE notify type. Deprecates the function
1599 silc_server_send_replace_id.
1601 * Added silc_server_send_notify_join to send the JOIN notify type.
1602 Deprecates the function silc_server_send_new_channel_user.
1604 * Added silc_server_send_notify_leave to send LEAVE notify type.
1605 Deprecates the function silc_server_send_remove_channel_user.
1607 * Added silc_server_send_notify_cmode and
1608 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1609 types. Deprecates the silc_server_send_set_mode function.
1611 * Added SERVER_SIGNOFF notify type to indicate that server has
1612 quit. This means that all clients on the channel from that
1613 server will drop. This can be also used when netsplit happens.
1615 Deprecated REMOVE_ID packet type since it is not needed anymore
1618 Added silc_server_send_notify_server_signoff to send the
1619 SERVER_SIGNOFF notify type. Deprecates the function
1620 silc_server_send_remove_id.
1622 Added also silc_server_send_notify_signoff to send the
1623 SIGNOFF notify type.
1625 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1626 SILC protocol from this day on. Changed the protocol
1627 specification as well.
1629 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1630 notify type. It is used between routers to notify about
1631 topic changes on a channel.
1633 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1636 * Partly updated the protocol specification to comply with the
1637 changes now made. It is still though a bit outdated.
1639 * The JOIN notify type now takes one extra argument <Channel ID>.
1640 The packet used to be destined to the channel but now the
1641 JOIN type may be sent as list thus it is impossible to
1642 destine it to any specific channel. By adding this argument
1643 it is again possible.
1645 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Added CREDITS file. The CHANGES and CREDITS file will appear
1648 in the distribution as well.
1650 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1653 types in the server's silcd/packet_receive.c.
1655 * Implemented CMODE and CUMODE to work in router environment.
1657 * Fixed minor encoding and decoding buglet from the
1658 lib/silccore/silcmode.c.
1660 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1663 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1665 * Changed all SilcConfigServer* and silc_config_server* to
1666 SilcServerConfig* and silc_server_config*, respectively.
1669 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Associated the ID (client or server ID) to the Authentication
1672 Payload to avoid any possibility of forging. Updated the
1673 protocol specification and the code accordingly.
1675 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * The RSA key length is now save to the RsaKey context in the
1678 key generation process in lib/silccrypt/rsa.c. The key length
1679 is now used to figure out the maximum size of the block allowed
1680 to be encrypted/signed.
1682 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1683 is equivalent to the silc_mp_mp2bin but does not allocate any
1686 * Changed silc_mp_mp2bin API to take length argument. If it is
1687 non-zero then the buffer is allocated that large. If zero, then
1688 the size is approximated using silc_mp_sizeinbase, which however
1691 * Created Global RNG API which is global RNG that application can
1692 initialize. After initializing, any routine anywhere in the
1693 code (including library) can use RNG without allocating a new
1694 RNG object. This was done to allow this sort of use of the
1695 RNG in code that has no chance to allocate RNG object. All
1696 applications currently allocate this and many routines in the
1697 library use this. Affected file lib/silccrypt/silcrng.[ch].
1699 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1700 it to use the Global RNG API.
1702 * Defined Authentication Payload into protocol specification that
1703 is used during SILC session to authenticate entities. It is
1704 used for example by client to authenticate itself to the server
1705 to obtain server operator privileges.
1707 Implemented this payload into the lib/silccore/silcauth.[ch].
1708 Implemented also routines for public key based authentication
1709 as the new protocol specification dictates.
1711 Moved definitions of different authentication methods from
1712 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1714 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1715 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1716 silc_pkcs_verify_with_hash functions into the file
1717 lib/silccrypt/silcpkcs.[ch].
1719 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * The client entry's userinfo pointer must be always valid.
1722 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1723 will fail since it requires the userinfo. Now, the userinfo
1724 is allocated as "" if actual userinfo does not exist. Actually,
1725 it must exist and it is totally Ok to drop client connections
1726 that does not announce the userinfo. However, we will make
1727 this workaround for now.
1729 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1730 to return the remote port by socket.
1732 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1735 SILC_SERVER_PENDING_EXEC and added an new macro
1736 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1737 data or when error occurs while processing the pending command.
1739 Added new argument `destructor' into silc_server_command_pending
1740 and to the SilcServerCommandPending object. This destructor is
1741 now called after calling the pending callback or if error occurs
1742 immediately. If error occurs the actual pending callback won't
1743 be called at all - only the destructor. The destructor may be
1744 NULL if destructor is not needed.
1746 All this applies for client library code as well. Similar
1747 changes were made there as well for the pending commands.
1749 In the client, the application must now allocate the
1750 SilcClientCommandContext with the silc_client_command_alloc
1753 * Added reference counter to the SilcServerCommandContext. Added
1754 function silc_server_command_alloc and silc_server_command_dup
1757 Same type of functions added to the client library for the same
1760 * Removed the cmd_ident from IDListData away since it is now
1761 global for all connections. It is the command identifier used
1762 in command sending and with pending commands. The affected file
1765 * Added reference counter to the SilcSocketConnection objecet to
1766 indicate the usage count of the object. The object won't be
1767 freed untill the reference counter hits zero. Currently only
1768 server uses this, and client ignores it. The client must be
1769 set to use this too later. The affected files are
1770 lib/silccore/silcsockconn.[ch]. Added also the function
1771 silc_socket_dup to increase the reference counter.
1773 This was mainly added because it is possible that the socket
1774 is removed underneath of pending command or other async
1775 operation. Now it won't be free'd and proper DISCONNECTING
1776 flags, etc. can be set to avoid sending data to connection that
1777 is not valid anymore.
1779 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1780 the connection. After that it sets SILC_SET_DISCONNECTED.
1781 It is, however, possible that the socket data is not still freed.
1782 The silc_server_packet_process now checks that data is not
1783 read or written to connection that is DISCONNECTED. The socket
1784 get's freed when the reference counter hits zero.
1786 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Changed the client operation API: channel_message operation's
1789 `sender' is now the client entry of the sender, not the nickname
1790 and the `channel' is the channel entry, not the channel name.
1792 In the private_message operation the `sender' is now also the
1793 client entry of the sender not the nickname.
1795 Affected file is lib/silcclient/ops.h and all applications
1796 using the client operations.
1798 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Moved the calling of ops->connect() from connect_to_server_final
1801 into receive_new_id functin since that is the point when the
1802 client is actually allowed to send traffic to network. The
1803 affected file is lib/silcclient/client.c.
1805 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1808 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1809 (if needs broadcasting) instead of broadcasting the packets one
1810 by one which would make a burst in the network traffic.
1812 * Added `broadcast' argument to the functions in silcd/server.[ch]
1813 silc_server_create_new_channel[_with_id] to indicate whether
1814 to send New Channel packet to primary router.
1816 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added new function into the silcd/server.[ch] files:
1819 silc_server_create_new_channel_with_id to create new channel with
1820 already existing Channel ID.
1822 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1823 lib/silccore/silcpacket.h. This packet is used t send list of
1824 Set Mode payloads inside one packet. Server uses this to set
1825 the modes for the channels and clients on those channels, that it
1826 announced to the router when it connected to it. The protocol
1827 specification has been updated accordingly.
1829 * The silc_server_new_channel did not handle the packet coming
1830 from normal server as it normally does not send that. However,
1831 when it announces its channels it does send it. Implemented
1832 the support for that.
1834 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1835 into the file lib/silccore/id.h.
1837 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Fixed memory leaks in the functions silc_idlist_del_client,
1840 silc_idlist_del_channel and silc_idlist_del_server in the file
1841 silcd/idlist.c. All of those leaked like a sieve.
1843 * Fixed some small memory leaks in the client's function
1844 silc_client_notify_by_server.
1846 * Added functions into silcd/server.c: silc_server_announce_clients,
1847 silc_server_announce_channels and silc_server_announce_server.
1848 These functions are used by normal and router server to announce
1849 to its primary router about clients, channels and servers (when
1850 router) that we own. This is done after we've connected to the
1853 These functions effectively implements the following packet types:
1854 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1855 and SILC_PACKET_NEW_ID_LIST.
1857 * Added new functions into the silcd/packet_receive.[ch]:
1858 silc_server_new_id_list, silc_server_new_channel_list and
1859 silc_server_new_channel_user_list to handle the incoming
1860 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1862 * Added support of changing Channel ID in the function
1863 silc_server_replace_id. If the server that announces a channel
1864 to the router already exists in the router (with same name but
1865 with different Channel ID), router is responsible to send
1866 Replace ID packet to the server and force the server to change
1867 the Channel ID to the one router has.
1869 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1870 client that the Channel ID has been changed by the router. The
1871 normal server sends this to the client. Client must start using
1872 the new Channel ID as the channel's ID.
1874 Implemented handling of this new type into lib/silcclient/client.c
1875 into the function silc_client_notify_by_server.
1877 * Added new function silc_idlist_replace_channel_id into the files
1878 silcd/idlist.[ch] to replace the Channel ID.
1880 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Call silc_server_command_identify_check always when processing
1883 the IDENTIFY command in silcd/command.c
1885 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1888 send keepalive packets. The packet can be sent by clients,
1889 servers and routers.
1891 Added function silc_socket_set_heartbeat into the file
1892 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1893 If not set, the heartbeat is not performed. The actual
1894 heartbeat is implemented in the low level socket connection
1895 library. However, application is responsible of actually
1898 Added silc_server_send_heartbeat to send the actual heartbeat
1899 packet into silcd/packet_send.[ch]. Server now performs
1900 keepalive with all connections.
1902 * Added silc_task_get_first function into lib/silcutil/silctask.c
1903 to return the timeout task with shortest timeout. There was a bug
1904 in task unregistration that caused problems. TODO has been
1905 updated to include that task system must be rewritten.
1907 * The client library will now resolve the client information when
1908 receiving JOIN notify from server for client that we know but
1909 have incomplete information.
1911 * Rewrote parts of silc_server_remove_from_channels and
1912 silc_server_remove_from_one_channel as they did not remove the
1913 channel in some circumstances even though they should've.
1915 * Encryption problem encountered in server:
1917 The LEAVE command used to send the Channel Key packet to the
1918 router immediately after generating it. However, the code
1919 had earlier sent Remove Channel user packet but not immediately,
1920 ie. it was put to queue. The order of packets in the router
1921 was that Channel Key packet was first and Remove Channel User
1922 packet was second, even though they were encrypted in the
1923 reverse order. For this reason, MAC check failed. Now, this
1924 is fixed by not sending the Channel Key packet immediately but
1925 putting it to queue. However, this is more fundamental problem:
1926 packets that are in queue should actually not be encrypted
1927 because packets that are sent immediately gets encrypted
1928 actually with wrong IV (and thus MAC check fails). So, packets
1929 that are in queue should be encrypted when they are sent to
1930 the wire and not when they put to the queue.
1932 However, the problem is that the current system has not been
1933 designed to work that way. Instead, the packet is encrypted
1934 as soon as possible and left to the queue. The queue is then
1935 just purged into wire. There won't be any fixes for this
1936 any time soon. So, the current semantic for packet sending
1939 o If you send packet to remote host and do not force the send
1940 (the packet will be in queue) then all subsequent packets to the
1941 same remote host must also be put to the queue. Only after the
1942 queue has been purged is it safe again to force the packet
1945 o If you send all packets immediately then it safe to send
1946 any of subsequent packets through the queue, however, after
1947 the first packet is put to queue then any subsequent packets
1948 must also be put to the queue.
1950 Follow these rules and everything works fine.
1952 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Added new function silc_server_remove_clients_by_server to
1955 remove all client entries from ID list when the server connection
1956 is lost. In this case it is also important to invalidate all
1957 client entires as they hold the invalid server entry. This
1958 fixes fatal bug when server has lost connection and will reconnect
1961 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Made some sanity checks to silc_server_daemonise like to check
1964 whether the requested user and group actually exists.
1966 * Added sanity check to SKE's silc_ske_responder_finish to check
1967 that the public and private key actually is valid.
1969 * Invalidate the client's nickname when receiving Replace ID
1970 packet and the Client ID is being replaced. This means that the
1971 server will query the nickname if someone needs it (client)
1974 * Sort the ID Cache in client library when the ID Cache data
1975 has changed (needs sorting).
1977 * Do not allow for SILC client to create several connections to
1978 several servers. The client does not support windows right now
1979 and generating multiple connections causes weird behaviour.
1981 Irssi-silc client does support windows and can handle several
1982 connections without problems, see: www.irssi.org and SILC plugin.
1984 * Fixed some places where client was added to the IDList. The
1985 rule of thumb is following (in order to get everything right):
1986 If the client is directly connected local client then the
1987 `connection' argument must be set and `router' argument must be
1988 NULL to silc_idlist_add_client function. If the client is not
1989 directly connected client then the `router' argument must
1990 bet set and the `connection' argument must be NULL to the
1991 silc_idlist_add_client function.
1993 * The funtion silc_server_packet_send_local_channel actually did
1994 not check whether the client was locally connected or not. It
1995 does that now. Fixed a bug related to LEAVE command.
1997 * Fixed Remove Channel User payload parsing bug in server's
1998 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2000 * The server's silc_server_save_channel_key now checks also the
2001 global ID list for the channel as it might not be in the local
2002 list. Fixed a bug related to LEAVE command.
2004 * Is this the end of the [<unknown>] buglet that has been lurking
2005 around for a long time? A little for loop fix in server's
2006 silc_server_command_whois_parse that is used by both IDENTIFY
2007 and WHOIS command. At least, this was a clear bug and a cause
2008 of one type of [<unknown>] buglet.
2010 * WHOIS and IDENTIFY commands call the function
2011 silc_server_command_[whois/identify]_check function even if
2012 we are not router server.
2014 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Added --with-gmp configuration option. If set the GMP
2017 is always compiled in the SILC source tree. If not set then
2018 it is checked whether the system has the GMP3 installed. If
2019 it has then the GMP won't be compiled (the system's headers
2020 and library is used), if it doesn't have it then the GMP is
2021 compiled in the SILC source tree.
2023 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Changed RSA private exponent generation to what PKCS #1
2026 suggests. We try to find the smallest possible d by doing
2027 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2028 not security fix but optimization.
2030 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Added new config entry [Identity] to fork the server and run
2033 it as specific user and group. A patch from Bostik.
2035 * Imported Dotconf configuration library into lib/dotconf.
2036 This will be used to create the SILC configuration files later.
2037 It will appear in the distsribution after this commit.
2039 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * A big code auditing weekend happening. Auditing code for
2042 obvious mistakes, bugs and errors. Also, removing any code
2045 Removed files for being obsolete:
2047 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2048 inline in the file lib/silcutil/silcbuffer.h)
2050 o lib/silcutil/silcbufutil.c (the header has inline versions)
2052 Changed code to fix possible error conditions:
2054 o The buffer formatting routines now check that the destination
2055 buffer really has enough space to add the data. This applies for
2056 both buffer formatting and unformatting
2057 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2058 unformatting was changed to accomodate following rules:
2059 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2060 sent to the function while XXX_*STRING will not allocate or copy
2061 the data into the buffer. Instead it sets the pointer from the
2062 buffer into the pointer sent as argument (XXX_*STRING used to
2063 require that the pointer must be allocated already). This change
2064 makes this whole thing a bit more consistent and more optimized
2065 (note that the data returned in the unformatting with XXX_*STRING
2066 must not be freed now). The routines return now -1 on error.
2068 o Tried to find all code that use buffer_format and buffer_unformat
2069 and added return value checking to prevent formatting and
2070 especially unformatting errors and possible subsequent fatal
2073 o Changed ske->x and ske->KEY to mallocated pointers in
2074 lib/silcske/silcske.h. Fixed possible data and memory leak.
2076 o Added return value checking to all *_parse* functions. Fixed
2077 many memory leaks as well.
2079 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2080 so that buffer overflows would not happen. All code now also
2081 checks the return value as it can fail.
2083 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Added reconnection support to server if the normal server looses
2086 its connection to the router (for example if router is rebooted).
2087 The server performs normal reconnection strategy implemented
2088 to the server. Affected file silcd/server.c.
2090 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added new packet type SILC_PACKET_SET_MODE that is used to
2093 distribute the information about changed modes (for clients,
2094 channels and clients channel modes) to all routers in the
2095 network. Updated the protocol specification accordingly.
2097 Added functions into silcd/packet_send.c and
2098 silcd/packet_receive.c: silc_server_send_set_mode,
2099 silc_server_set_mode.
2101 Added new files silcmode.[ch] into lib/silccore that implements
2102 the encoding and decoding of Set Mode Payload. Added new type
2103 SilcSetModePayload. Moved the definitions of different modes
2104 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2106 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Oops, a little mistake in server's connection authentication
2109 protocol. The protocol is not ended with FAILURE but with
2110 SUCCESS if the authentication is Ok. :) Affected file is
2113 * Implemented NICK_CHANGE notify handling in server in the file
2114 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2115 the local clients on the channel. After the changing nickname
2116 in router environment snhould work and the [<unknown>] nickname
2117 should appear no more.
2119 The silc_server_replace_id function that receives the Replace ID
2120 payload now sends the NICK_CHANGE notify type also in the file
2121 silcd/packet_receive.c
2123 * Changed WHOIS and IDENTIFY command to support the maximum amount
2124 of arguments defined in protocol specs (3328 arguments). This
2125 fixed a bug that caused problems when there were more than three
2128 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Added extra parameter, command identifier, to the
2131 silc_client_send_command so that explicit command identifier
2134 Changed that ID list routines uses specific command identifier
2135 when sending WHOIS/IDENTIFY requests to the server so that they
2136 can be identified when the reply comes back.
2138 Affected files lib/silcclient/command.[ch],
2139 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2141 * Added `sender' argument to silc_server_packet_send_to_channel
2142 to indicaet the sender who originally sent the packet to us
2143 that we are now re-sending. Ignored if NULL. Affected file
2144 silcd/packet_send.[ch].
2146 * Added some server statistics support in silcd/server_internal.h
2147 SilcServerStatistics structure and around the server code. Also
2148 send some nice statistics information when client is connecting
2151 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Fixed channel ID decoding in server's JOIN command reply in
2154 silcd/command_reply.c
2156 * Fixed braodcasting of replace ID payload to not to send it if
2157 we are standalone server in silcd/packet_receive.c.
2159 * Fixed all channel message sending routines to not to send
2160 packets to clients that has router set, since they are routed
2161 separately in the same function earlier. Affects file
2162 silcd/packet_send.c and all channel packet sending functions.
2164 * In USERS reply, res_argv[i] are not allocated, the table
2165 is allocated. Thus changed that free the table, not its
2168 * In server's whois_check and identify_check if the client is
2169 locally connected do not send any WHOIS commands - they are not
2172 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Fixed some minor bugs in client when sending WHOIS command. The
2175 arguments was in wrong order.
2177 * Removed statis function add_to_channel from server in
2178 silcd/command.c that was previously used with the joining but
2181 * Tested USERS command in router environment successfully with two
2182 routers, two servers and two clients.
2184 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Reorganized the USERS command and command reply in client library
2187 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2188 When the command is given by user we register a pending command
2189 callback that will reprocess the command after the reply has been
2190 received from the server. When reprocessing the packet we then
2191 display the information. Thus, the USERS information is displayed
2192 now in the command callback instead of in the command reply
2193 callback. The processing of the command is same as previously
2194 when server has sent the command reply in the JOINing process.
2196 * Added to USERS command in silcd/command_reply.c to join the client,
2197 we didn't use to know about, to the channel after we've created
2198 a client entry for it. Also, for clienet we did know already still
2199 check whether it is on the channel or not and add it if not.
2201 * Removed silc_server_command_join_notify as the function and its
2204 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Changed the client's pending command handling to the same as the
2207 server's pending command handling. It is also now possible to
2208 execute command reply functions from other command reply
2209 function as the function callbacks for commands and command
2210 replies are one and same. The pending commands are not static
2211 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2212 in client connection context. Thus, pending commands are server
2213 connection specific as it is convenient.
2215 Changed the function silc_client_command_pending and
2216 silc_client_command_pending_del and added new function
2217 silc_client_command_pending_check. Removed the
2218 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2221 * Added cmd_ident, current command identifier, to the client
2222 connection context in lib/silcclient/client.h to keep track on
2223 command identifiers used in command sending. Client's command reply
2224 function handling now supports the mandatory command identifiers.
2226 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2227 funtions in client to fully support pending command callbacks.
2229 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2230 as one of the arguments to the application in the command reply
2233 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2234 before first releasing SILC but came back. Now it is removed again
2235 and should come back nomore. The FORWARDED flag was used only
2236 by the JOINing procedure by forwarding the command packet to router.
2237 Now, the JOINing procedure has been changed to more generic (due
2238 to various router environment issues) and FORWARDED is not needed
2239 anymore for anything. The protocol specification is yet to be
2242 Now, removed silc_server_packet_forward from server and the flag
2243 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2245 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Renamed NAMES command to USERS command. The NAMES was named that
2248 due to historical reasons. Now it is renamed. Also, rewrote
2249 parts of the USERS command. The nickname list is not sent anymore
2250 by the server. Only Client ID and mode lists are sent in the USERS
2251 command. Changed this also to the protocol specification.
2253 The client now resolves the names and stuff after it receives
2254 the USERS list from the server when joining to the channel.
2256 * WHOIS and IDENTIFY commands has been changed to support multiple
2257 Client ID's per command. One can now search for multiple users
2258 in the network by sending only one WHOIS or IDENTIFY command.
2259 Changed the code and the protocol specifications.
2261 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2262 uses silc_server_command_whois_parse to parse the request. */
2264 * If normal server, do not parse the WHOIS and IDENTIFY requests
2265 before sending it to the router. Saves some time.
2267 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Fixed JOIN command on client library. Wrong number of arguments
2270 used to crash the client.
2272 * Added silc_server_channel_has_global function to check whether
2273 channel has global users or not.
2275 * Added silc_server_channel_has_local function to check whether channel
2276 has locally connected clients on the channel.
2278 * The silc_server_remove_from_one_channel now checks whether the
2279 channel has global users or not after given client was removed from
2280 the channel. It also checks whether the channel has local clients
2281 on the channel anymore. If it does not have then the channel entry
2282 is removed as it is not needed anymore.
2284 * The silc_server_notify now checks on JOIN notify whether the joining
2285 client is one of locally connected or global. If it is global then
2286 the channel has now global users on the channel and that is marked
2287 to the channel entry. Also, it now saves the global client to
2288 global list who is joining and JOINs it to the channel. This is
2289 for normal server, that is.
2291 Changed silc_server_send_notify_on_channel,
2292 silc_server_packet_relay_to_channel and
2293 silc_server_packet_send_to_channel check if we are normal server
2294 and client has router set (ie. global client) do not send the
2295 message to that client, as it is already routed to our router.
2297 * Implemented LEAVE notify type handling in silc_server_notify
2300 * Tested LEAVE command in router environment successfully. Tested
2301 with two routers, two servers and two clients.
2305 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2307 * Implemented SIGNOFF notify type handling in silc_server_notify
2310 * silc_server_remove_id now removes the client entry from all channels
2311 it has joined and thusly sends SIGNOFF notify type.
2313 * Rewrote the NAMES list generation in server by removing two excess
2314 loops. The lists are created now inside one loop.
2316 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * silc_server_remove_channel_user checks now also global list
2319 for channel and client.
2321 * silc_server_new_channel_user checks now both local and global
2322 list for channel and client. Fixed a bug in client id decoding.
2323 Used to decode wrong buffer.
2325 * silc_server_channel_message checks now both local and global
2326 list for channel entry.
2328 * Tested channel joining (hence JOIN) in router environment
2329 successfully. Tested with two routers, two servers and two
2332 * Tested channel message sending in router environment successfully.
2334 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Added silc_server_save_channel_key into server.[ch] to save the
2337 received channel key in Channel Key payload processing. It is
2338 also used in JOIN command reply handling.
2340 Equivalent function silc_client_save_channel_key added into
2341 client.[ch] into client library.
2343 * Changed JOIN command reply to send information whether the channel
2344 was created or not (is existing already) and the channel key
2345 payload. Changed protocol specs accordingly.
2347 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2348 the request was sent by ID and not by nickname. Crashed on
2351 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2354 now correctly save the received data.
2356 * silc_server_free_sock_user_data now notifies routers in the
2357 network about entities leaving the network.
2359 At the same time implemented functions silc_server_remove_id
2360 and silc_server_send_remove_id to receive and send REMOVE_ID
2361 packets. The packet is used to notify routers in the network
2362 about leaving entities. The ID removed will become invalid in
2365 * Added function silc_idlist_del_server into server. Removes and
2366 free's server entry from ID list.
2368 * silc_server_private_message function now checks, if we are router,
2369 that the destination ID really is valid ID, naturally.
2371 * In router when NEW_ID packet is received (for new client) the
2372 hash of the Client ID is saved in the ID Cache but the
2373 client->nickname is set to NULL, instead of putting the hash
2376 IDENTIFY command now also checks that client->nickname must be
2377 valid. If it is not if will request the data from the server who
2378 owns the client. Added new function
2379 silc_server_command_identify_check.
2381 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2382 to set the command to already allocated Command Payload.
2384 * Tested private message sending in router environment with two
2385 routers, two servers and two clients. Fixed minor bugs and now
2388 * Fixed segfault from client's NAMES command. Used to crash if
2391 * Forwarded packets must not be routed even if it is not destined
2392 to the receiver. Changed server code comply with this.
2394 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added `require_reverse_mapping' boolean value to ServerParams
2397 structure. If TRUE (not default) the server will require that
2398 the connecting host has fully qualified domain name.
2400 If the reverse mapping is not required and hostname could not be
2401 found the IP address is used as hostname.
2403 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Implemented version string checking to both client and server.
2406 The check is incomplete currently due to the abnormal version
2407 strings used in development version of SILC.
2409 * Changed all command functions in server to use the new
2412 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Changed char *data to unsigned char *data in ID Cache system to
2415 support binary data as ID Cache data. Changed code to support
2416 binary data in lib/silccore/idcache.c.
2418 * Renamed silc_server_packet_relay_command_reply to
2419 silc_server_command_reply as it is normal packet receiving
2420 function. Rewrote the function to accept command replys for
2421 servers and not only for clients.
2423 * Mark remote router always as registered server if we are connecting
2424 to it. Otherwise, commands sent by the router to us are ignored.
2426 * All ID List find routines now returns the ID Cache Entry pointer
2427 as well if requested.
2429 * WHOIS command works now in router environment, tested with two
2430 routers, two servers and two clients.
2432 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2433 in router environment (as it is almost equivalent to WHOIS) but
2434 hasn't been tested thoroughly. Added new functions:
2436 silc_server_command_identify_parse
2437 silc_server_command_identify_send_reply
2438 silc_server_command_identify_from_client
2439 silc_server_command_identify_from_server
2441 * Disabled route cache adding because adding two different ID's with
2442 same IP replaces the old cache entry thus giving wrong route.
2443 The entry->router->connection is always the fastest route anyway
2444 so route cache may not be needed. Of course, new routes maybe
2445 established after receiving the ID when the entry->router->connection
2446 might not be anymore the most optimal.
2448 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Add route cache for received ID for fast routing.
2452 * Added silc_server_packet_route to route received packet on router
2453 that is not destined to us.
2455 * Renamed silc_server_get_route to silc_server_route_get.
2457 * Added id_string and id_string_len fields into SilcServer to
2458 include encoded ServerID for fast comparing without excess
2459 encoding of the ID's.
2461 * Cleaned up WHOIS command on server side. Added following static
2464 silc_server_command_whois_parse
2465 silc_server_command_whois_check
2466 silc_server_command_whois_send_reply
2467 silc_server_command_whois_from_client
2468 silc_server_command_whois_from_server
2470 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2471 arguments in command replies. All command functions should be
2472 updated to use this macro.
2474 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Minor typo fixes on command reply handling on server.
2478 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Added silc_server_command_add_to_channel internal routine to add
2481 the client to the channel after router has created the channel and
2482 sent command reply to the server.
2484 * Added generic silc_server_send_command to send any command from
2487 * Use static buffer with ID rendering instead of duplicating data.
2489 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Fixed a channel user mode bug when joining to a channel server gave
2492 everybody channel founder rights, oops.
2494 * We mark ourselves as the router of the incoming server connection
2495 if we are router ourselves. This way we can check in some packet
2496 sending functions whether it is locally connected server. For
2497 incoming router connections we put NULL.
2499 * For router sending packets locally means now always sending the
2500 packet cell wide; to local clients and local servers. For normal
2501 server sending packet locally means sending it to only local
2504 * Fixed the JOIN command to really work in router environment. If the
2505 channel is created it is always created by the router. Router is
2506 also responsible of making the initial joining to the channel,
2507 sending JOIN notify to the sending server and distributing
2508 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2509 does not exist server doesn't do anything else but forward the
2510 command to the router which performs everything.
2512 * Added silc_server_send_channel_key function to send the Channel Key
2515 * Added silc_server_create_channel_key to create new channel key. The
2516 channel key is now re-generated everytime someone joins or leaves
2517 a channel, as protocol dictates. Note: channel->key_len is the
2520 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2523 packet_receive.[ch] to separate packet sending and receiving
2524 routines. The server.[ch] now includes everything else including
2525 actual packet processing (writing and reading data) and other
2528 Renamed silc_server_private_message_send_internal to
2529 silc_server_send_private_message. The routine is still though
2530 used only to relay private messages as server does not send
2531 private messages itself.
2533 Renamed silc_server_new_channel to silc_server_create_new_channel
2534 and added new function sicl_server_new_channel that handles the
2535 incoming New Channel packet. Added also new sending function
2536 silc_server_send_new_channel to send New Channel Payload.
2538 * Added new function silc_server_notify to process incoming notify
2539 packet to the server/router. Server may then relay the notify
2540 to clients if needed.
2542 * Added new function silc_server_new_channel_user to process incoming
2543 New Channel User packet. Router will redistribute the packet and
2544 send JOIN notify to its local clients and locally connected servers
2545 if needed. Normal server will send JOIN notify to its local client
2546 on same channel when received this packet. Added also corresponding
2547 sending function silc_server_send_new_channel_user to sent the
2550 * Added boolean route argument to send_notif_to_channel and
2551 packet_send_to_channel functions to attempt to route the packet
2552 if it is TRUE and send only locally if it is FALSE.
2554 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * silc_server_replace_id now broadcasts the received replace ID
2557 packet if it is not broadcast packet already. The router must
2558 broadcast to inform other routers about changed ID.
2560 * Added backpointer to server's router into SilcServer context in
2561 silcd/server_internal.h.
2563 * Fixed silc_server_packet_broadcast to send correct broadcast
2566 * The channel key is now distributed to the local client as soon
2567 as it is received from the router (in router environment) so that
2568 no other packet may be sent for the channel until client has
2571 * silc_server_remove_channel_user now broadcasts the received
2572 Remove Channel User packet if it is not broadcast packet already.
2573 The router must broadcast to inform other routers about removed
2576 * Added users field into SilcPacketContext that is a reference count
2577 of the context. One can increase the reference count by calling
2578 silc_packet_context_dup which is now changed to just increase the
2579 reference count instead of duplicating the data. The reference
2580 count is decresed by calling silc_packet_context_free that will
2581 free the data after the reference count hits zero.
2583 For now on the packet context and everything allocated into it
2584 (including the raw packet from network) must be freed by calling
2585 the new silc_packet_context_free function. Added also new function
2586 silc_packet_context_alloc that must be used now to allocate the
2587 context. This also means that if a routine is asynchronous from
2588 silc_[client/server]_packet_parse_type the packet context must
2589 be duplicated by calling silc_packet_context_dup. Otherwise it
2590 gets free'd after silc_[client/server]_packet_parse_type returns.
2591 Also, one must remember that if packet is duplicated then its
2592 reference count must be decresed by calling the free function as
2593 many times as it was duplicated.
2595 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2596 from both client and server.
2598 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2600 * Made joining to a channel working in router environment.
2602 * Cleaned up JOIN command on server side and create function
2603 silc_server_command_join_channel internal routine to make the
2606 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Changed silc_command_pending list to SilcDList. Also, added
2609 `ident' field to SilcServerCommandPending structure to identify
2610 the reply and to call correct callback.
2612 Added silc_server_command_pending_check function to replace the
2613 corresnponding macro. The silc_command_pending list is not
2616 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2617 to set identifier to previously allocated Command Payload. It
2618 is used to set identifier for command when resending Command
2621 * Added silc_command_payload_encode_payload to encode Command
2622 Payload buffer from SilcCommandPayload structure.
2624 * Added silc_argument_payload_encode_payload to encode Argument
2625 payload buffer from SilcArgumentPayload structure.
2627 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Changed WHOIS command to support router connection on server side.
2630 The whois request is always sent to router unless the server is
2631 standalone server. After server has received the reply from the
2632 router will it send the reply to the client.
2634 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2635 broadcast received broadcast packet. The function is used only
2636 by router. The broadcast packet is always sent to the router's
2639 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2640 render given ID to printable string, for log files for example.
2642 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Made basic router to router connections working. At least they
2645 can now connect to each other but nothing really works the way
2646 they are supposed - yet.
2648 * Added new initiator token to RouterConnection configuration
2649 file in silcd/serverconfig.[ch]. It is used to tell whether we
2650 are the initiator to the remote router or whether we'll expect
2651 the other end to connect.
2653 * Moved registering of listener task to silc_server_init, hence
2654 the server starts listenning as soon as it is run, even if it
2655 does not have connections to other routers. Let's see how well
2658 * Changed default connection retry timeouts for more suitable in
2661 * Removed cipher and such arguments from silc_idlist_add_client
2662 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2663 Added new function silc_idlist_add_data to add the keys and stuff
2666 * Added SilcIDListData structure and added it to SilcClientEntry
2667 and SilcServerEntry as their first field in the structure. This
2668 way we can explicitly cast the ID entries to the SilcIDListData
2669 structure and get common data for the entries. In past, we had
2670 to first check what type of connection it is and then cast it to
2671 correct ID entry type. Now, we can directly cast the opaque
2672 pointer to the SilcIDListData (no matter what ID entry it actually
2673 is) and get the data needed.
2675 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2678 in some circumstances even if threre were timeout tasks, though not
2679 IO tasks, but tasks anyway. Now fixed.
2681 * Defined SilcServerConnection structure to hold connection specific
2682 stuff about directly connected servers and routers. The definition
2683 is currently in silcd/server_internal.h. I thought about having
2684 a bit more important role fro this struct but for now it is used
2685 only when connecting to other server (or router actually).
2687 * Added connecting retry support in server when connecting to
2688 router(s). The retry feature implement exponential backoff
2689 algorithm. Also, added SilcServerParams structure to hold default
2690 parameters for server. For now, it include these retry settings
2691 and are hard coded. After server is moded to be as Silc Server
2692 Library this structure will be more important.
2694 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Changed client librarys channel->clients table to SilcList and
2697 changed code accordingly.
2699 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Changed client's channel table to SilcList and changed code
2702 accordingly. Also changed SilcChannelClientEntry to include back-
2703 pointer to the channel so that client entry can use that structure
2704 as list as well and we have fast cross-reference to the channel.
2705 This change dramatically decreased the complexity of channel
2706 handling with client entry and vice versa (removed one extra
2707 loop when searching for channel entry from many functions).
2709 * Changed server->sim from table to SilcDList and changed code
2712 * NAMES command can now be used from user interface. It will show
2713 the user list on the channel, neatly.
2715 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2716 Code now saves realname of the user if it becomes available.
2718 * Renamed configure.in to configure.in.pre and made ./prepare
2719 script to automatically add correct version string to
2720 configure.in which it creates from configure.in.pre.
2722 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * NAMES command reply now shows users mode with the nickname when
2727 * Moved silc_client_ch[u]mode[_char] functions from
2728 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2729 place sucks, they are utility functions and should be in some
2732 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2734 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2737 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Added TRQ (efficient deque and list library) into lib/trq. This is
2742 a very good list library that is currently used in the SILC. Defined
2743 SilcList API over the library because I didn't like the API very
2744 much. See lib/trq/silclist.h for the API and examples of how to
2745 use the API. Fixed various places in the code to use the new
2746 SilcList API. The SilcList is meant for lists that has a structure
2747 already defined as a list. It is not suitable to add just some
2748 context to the list (in TRQ, the context is the list actually).
2750 So, I defined SilcDList that can be used for the purpose where
2751 predefined list structure does not exit. This can be used as
2752 such list. Now some context just can be added to the SilcDList.
2753 Currently this list is not used in the SILC just yet, though there
2754 are a lot places where this can replace dynamically allocated
2755 tables and I will fix these places, later, to use SilcDList.
2756 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2757 and use TRQ internally).
2759 Also fixed some annoying warning messages that the original TRQ
2760 code generated. Also minor changes to TRQ's Makefile.in.
2762 * Added support for querying by Client ID to both WHOIS and
2763 IDENTIFY commands into server, as required by the protocol.
2765 * Removed method function pointers from SilcBuffer structure. They
2766 weren't used to anything and just increased the context size for
2767 no good reason. This change also made silc_buffer_alloc and
2768 silc_buffer_free functions inline functions.
2770 * Disabled command flooding detection support until it's fixed so
2771 that it accepts commands in but does not execute them more than once
2774 * Added silc_net_localhost(), to return local hostname, into
2775 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2776 that must be initialized before calling silc_client_init.
2778 * Added new function: silc_server_send_notify_on_channels to send
2779 notify messages to all channels client has joined. It is assured
2780 that the message is sent only once per client.
2782 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2783 lib/silcutil/silcutil.[ch] as silc_format function. The new
2784 function is generic and is used by server as well, not only by
2785 the logging routines.
2787 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2788 the provided version string was not acceptable. Added new function:
2789 silc_ske_check_version into lib/silcske/silcske.h. The function
2790 must be implemented by the application (client or server) and it
2791 does not reside in the SKE library. The function checks the version
2792 string remote end sent.
2794 * Added back pointers (to opaque context and to SilcSocketConnection)
2795 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2797 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2798 duplicate packet context structure.
2800 * Changed `notify' client operation to send same arguments as client
2801 receives from server except for ID's. ID's are mapped to correct
2802 ID entry and that is returned. Also, if channel entry is not sent
2803 by server but the notify is for channel the channel entry is sent
2804 to application (otherwise application doesn't know that it is for
2805 channel (library gets it from packet's Destination ID)).
2807 * Added silc_client_remove_from_channels into client library to
2808 remove a client from all channels it has joined to. Used when
2809 received SIGNOFF notify from server. Added also new function
2810 silc_client_replace_from_channels to replace old ID entry with
2811 new ID entry on all channels. Used when received NICK_CHANGE
2814 * Fixed ID Cache list handling in silc_idlist_get_client in
2815 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2816 to get (or query) client by ID.
2818 * Updated TODO list.
2820 * Added connection authentication status message defined by the
2821 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2822 support for these into the code in client and server side.
2824 * Added generic function silc_client_send_command to send any command
2825 with variable argument list. Application should use this function
2826 to send commands if the command functions provided by the library
2827 does not suite for the application's user interface needs.
2829 * Added new `failure' client operation. Application is notified about
2830 received failure packet if client is executing a protocol. In this
2831 case the protocol's execution has failed.
2833 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2834 is required by the protocol.
2836 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2837 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2840 * Added status flag to SilcSKE object to indicate realtime status
2841 of the SKE protocol.
2843 * Application receives now exactly same command reply arguments as
2844 the library receives from server. However, if ID is received the
2845 corresponding ID entry is returned to the application (eg. Client
2846 ID is mapped to correct SilcClientEntry entry and that is returned).
2847 Changed command_reply client operation due to this change.
2849 * Changed all ID's in commands and in command replys as ID Payloads.
2850 Change affected both client and server side codes.
2852 All ID's sent in SILC network (with execption of ID's in SILC
2853 Packet header) are sent in ID Payload to support variable length
2856 * Server now notifies nick changes and notifies all clients on
2857 the channels about the new nickname (about the new Client ID,
2860 * Implemented CMODE command to change channel modes. Supports all
2861 channel modes defined by the protocol specs except ban and invite
2862 lists. (Also, private channel key mode is supported but support for
2863 setting private channel key in client is missing, thus, this mode
2864 has no effect on client side (except that server requires that the
2865 client uses private channel key and normal channel traffic does not
2868 Also, invite mode works per se, but INVITE command does not work
2869 yet correctly, so you can set channel as invite only channel but
2870 inviting clients to the channel does not work (it is yet to be
2871 thought what's the best way to do it).
2873 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2874 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2875 Implemented CUMODE command to change user's mode on the channel.
2876 Supports all modes defined by the protocol specs.
2878 * Added NAMES command reply to return users modes on the channel.
2880 * Removed unnecessary and slow ciphers from lib/silccrypt.
2882 * Set SO_KEEPALIVE option to connection sockets by default.
2884 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2886 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2887 redefined the Notify Payload into protocol specs.
2889 * Added silc_id_payload_parse_id to get ID directly from raw
2892 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2895 accept searching by Client ID as well.
2897 * Added support for LEAVE and SIGNOFF notify types in client library.
2899 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2900 to parse ID Payload from raw data.
2902 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Added flags parameter into silc_ske_assemble_security_properties
2905 function in lib/silcske/silcske.[ch].
2907 * Changed notify client operation to fit better for notify messages
2908 sent by server. The notify payload received from server is now
2909 passed to the application (after parsing it to SilcNotifyPayload).
2910 It is application's responsibility to retrieve the arguments
2911 from the payload and show the message the way it wants. The message
2912 sent by server is implementation specific.
2914 * Changed public keys to comply with the protocol specification.
2915 Old public keys are not supported anymore and are not compatible.
2917 * Removed nickname from Channel Payload as the latest draft removed
2918 it. The client must resolve the nickname from the NAMES command
2919 reply received when it joined the channel.
2921 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2923 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Fixed some errors in protocol specification drafts.
2927 * Created lib/silccore/silcnotify.c to implement Notify Payload
2928 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2929 generic payloads described by protocol specifications. The file
2930 includes implementations for ID Payload and Argument Payload.
2932 * Changed Command Payload implementation to use the new Argument
2933 Payload. Changed command_xxxx_payload to command_payload_xxxx
2934 to comply with SILC coding conventions.
2936 * Added suppport for Argument Payload handling in Notify Payload
2937 implementation as protocol requires it. Added the new support
2938 into server and client lib as well.
2940 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Added support for multiple nicknames on same channel. [n] is
2943 added locally to the nickname if there are more than one same
2944 nicknames on the channel.
2946 * Server now sends all nicknames that matched WHOIS request.
2947 Client also shows the list received from server.
2949 * Added TOPIC command to client side. User can now set and show
2950 current topic on channel.
2952 * Added MOTD command to client and server. Also, server sends the
2953 motd when client connects to the server.
2955 * Changed version strings to comply ISO 8601.
2957 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Fixed protocol error handling in client library. It should now
2960 cope even if the SKE fails for some reason.
2962 * Made new protocol specification drafts for submitting to IETF.
2964 * Implemented TOPIC command to server in silcd/command.c.
2966 * Added two new notify types into lib/silccore/silcnotify.h:
2967 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2968 notify nickname change and topic setting/change on a channel.
2970 * API change of command_reply operation in client library. The
2971 application gets now the status type received from server as well.
2973 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2977 * Cras fixed and optimized the packet handling even further and
2978 it should work now. Minor change to the prototype of function
2979 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2981 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Added new function into lib/silcutil/silcschedule.[ch]:
2984 silc_schedule_with_fd to select() a specified fd. The function
2985 returns after timeout expires or data arrives or goes. The
2986 function is used by packet routines to wait that all data is
2987 received from network.
2989 * Fixed data reading from network in lib/silccore/silcpacket.c.
2990 The code now assures that all data is read from the fd and then
2991 continues packet processing. This was a bug fix since the code
2992 used to drop some data in some circumstances.
2994 * Added new function into lib/silcclient/client.[ch]:
2995 silc_client_start_key_exchange to start key exchange after
2996 connection has been established to server. The code internally
2997 now uses this funtion but its main purpose was to provide it
2998 for applications that perform their own connecting. After
2999 application has created a connection it merely calls this
3000 function to start the key exchange between client and server.
3001 The library takes care of everything else after that.
3003 Updated also lib/silcclient/README to explain the usage of
3006 * Do not send to application information that connection has
3007 been established. Application gets notified it by connect
3010 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Applied cras's patch to add silc_schedule_one function. The
3013 function runs scheduler once and returns.
3015 * Fixed the scheduler after cras messed it up. The timeout
3016 handling works now as it's supposed to work.
3018 * Added into lib/silccore/ silcnotify.h to include notify
3019 message types support. Changed silc_server_send_notify*
3020 functions, in server.[ch], to support those new notify types.
3021 Added the support for the notify types into client library,
3022 as well. Added new notify client operation into ops.h in
3025 * Changed silc_server_packet_send_to_channel to send normal
3026 packets instead of just channel message packets. The function
3027 is now used to send the notify packets to channels. It is not
3028 used to send channel message packets anymore, as server never
3031 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3032 va_arg()s as it seems to require it nowadays. I guess, if SILC
3033 is compiled with older va_arg() the new code should work anyway.
3035 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Splitted core library. Core library (lib/silccore) includes
3038 now only SILC protocol specific core (and common) components.
3039 Created new utility library (lib/silcutil) that includes more
3040 generic purpose stuff. The stuff for util library was taken
3041 from the old core library. This was minor and easy split.
3043 * Created SILC Client Library (lib/silcclient) that includes
3044 implementation of the SILC client without user interface. This
3045 was major move from silc/ directory. The code has been changed
3046 so that it is transparent towards the user interface. The
3047 silc/ directory includes now the same user interface as before
3048 and it uses the new client library. Read lib/silcclient/README.
3049 Basicly, the client library performs everything else related
3050 to SILC except user interface handling. Also, configuration
3051 files are considered to be part of user interface and library
3052 does not handle them.
3054 This change also changed a lot of structures, function naming etc.
3055 Most important change was that SilcClientWindow object was
3056 renamed to SilcClientConnection in the client library. Created
3057 also new file lib/silcclient/ops.h. Also added new files
3058 silc/local_command.[ch] and silc/client_ops.[ch].
3060 All these changes were made to make it easier for user interface
3061 designers to create what ever user interface for the SILC client
3064 It is also expected that the server will be moved to lib
3065 directory as well and SILC Server Library will be created;
3066 sometimes in the future.
3068 * Removed Local commands from lib/silccore/silccommand.h as
3069 they are application specific and new client library does not
3070 handle any of those anymore.
3072 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3073 old client implementation in silc/.
3075 * Added support for callback functions in SILC_LOG_* macros.
3076 Application can now set its own callbacks that will be called
3077 instead of using the default functions that will always print
3078 the debug messages to stderr (or stdout). Also, debugging can
3079 now be disabled by setting silc_debug to FALSE and re-enabled by
3080 setting it to TRUE. Note, that logging will still work even
3081 if debugging is disabled.
3083 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3084 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3085 silc_log_reset_debug_callbacks.
3087 * To enable debugging in silc client one must give now -d
3088 option on command line.
3090 * Changed silc_schedule_init to automatically allocate task queues
3091 if they are not allocated before calling it.
3093 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * Added GMP 3.1 into math library.
3097 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3100 a channel in SILC network. The packet is used by servers and
3101 routers to notify other routers that user has left a channel.
3102 This little feature was missing until now. Added the feature
3103 to protocol specification as well.
3105 Added functions: silc_server_send_remove_channel_user and
3106 silc_server_remove_channel_user into server.[ch].
3108 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3109 lib/silccore/silcpacket.h. However, they are not implemented
3112 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Fixed joining to a channel and sending channel messages
3115 between server and router. The channel message sending should
3116 now work inside a cell.
3118 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Fixed the private message sending between server and router.
3121 The private message sending should now work inside a cell.
3123 * Added silc_server_replace_id into server.[ch] to replace
3124 existing ID in the SILC network.
3126 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3127 and silc_idlist_replace_server_id into idlist.[ch] in server.
3129 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Fixed the server to server connections. Server can again now
3132 connect to router. Router to router connections probably does
3135 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Added dynamic protocol registering support. Now protocols can
3138 registered and unregistered on the fly. Patch by cras.
3140 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Added lib/contrib directory to hold routines that some platforms
3143 don't have but are needed by SILC.
3145 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3146 into lin/contrib to provide getopt() and getopt_long() for
3147 those who don't have it.
3149 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Added AWAY command to client. When away message is set and
3152 client receives a private message packet the client automatically
3153 replies to the sender with the away message.
3155 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3156 bug seemed to be the cause of recent problems when compiling
3159 * Added version detection support to SKE protocol specification
3160 and added the new changes to the SKE implementation as well.
3161 There were other minor changes in the SKE protocol as well.
3163 Many changes in lib/silcske/silcske.[ch] and in
3164 lib/silcske/payload.[ch].
3166 * Added ^U functionality, clear input line. Patch from cras.
3168 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Mainly small bugfixes on core library. Fixed some debugging
3171 logging and buffer overflow in silclog.c.
3173 * Updated config.sub and config.guess on the distribution tree.
3175 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added command lagging support in server. Client may execute
3178 commands now only once in two seconds.
3180 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Optimized packet reception. MAC computation and checking is now
3183 also more optimized. A lot previously duplicated code is now
3184 used as generic by both client and server.
3186 * Fixed key pair generation in clientutil.c
3188 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Added into lib/silccore/silcbufutil.[ch] new function;
3191 silc_buffer_realloc.
3193 * Moved generic packet sending/encryption functions to
3194 lib/silccore/silcpacket.[ch] from client and server. Some
3195 rewriting of the functions.
3197 * Moved all generic packet reception/decryption functions to
3198 lib/silccore/silcpacket.[ch] from client and server. The
3199 packet processing is now much cleaner in both client and server.
3200 These were major changes in both client and server.
3202 * Created many common functions in server to do packet sending.
3203 Previously code were duplicated a lot, this has been removed
3206 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Rewrote major parts of the ID cache system. Don't know
3209 whether it is better now or not but at least the API is more
3212 * Major rewrite on ID cache stuff on client because of the ID
3213 cache API changes. Added idlist.c to client.
3215 * Also major rewrite on ID cache stuff on server as well.
3216 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3217 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3218 in hand, instead they are all put into the ID cache system now.
3219 All server_idlist_* routines uses ID cache now instead of
3220 traversing its own lists (those lists does not exist anymore).
3221 SilcIDList though still exists. Also, SilcXXXEntry's are
3224 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Finally made the SKE implementation compliant to the protocol
3227 specification. All mp integers are now binary encoded as
3228 opposed being HEX encoded.
3230 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3233 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3234 functions: silc_[encode/decode]_pem. Also added function
3235 silc_encode_pem_file to PEM encode with newlines ('\n') for
3238 * SILC public keys are now encoded either PEM or binary. Same
3239 option is for private keys as well. By default private keys
3240 are binary encoded and public keys PEM encoded. Silly HEX
3241 encoding were removed.
3243 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3244 function to create fingerprints.
3246 * Fixed a bug in SHA1; does not change the original data anymore.
3248 * Partly implemented INFO command on client and server side.
3249 Fixed CLEAR command. Changes to SERVER command; show current
3250 server(s) when giving command without arguments. Added
3251 VERSION command to client.
3253 * Added check to server that unregistered connections cannot
3254 execute commands (unless it is specificly allowed).
3256 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Fixed screen refresh.
3260 * Fixed channel joining bug from client. On some circumstances
3261 client tried to join to a channel it had already joined.
3263 * Added public key verification process into client's protocol.c.
3264 The client now verifies the public key from user and saves
3265 it into ~./silc/serverkeys/ directory.
3267 Added into: clientutil.[ch]: silc_client_verify_server_key.
3269 * Changed SKE protocol's silc_ske_initiator_finish function
3270 to accept callback function that verifies the received public
3271 key. Removed old silc_ske_verify_public_key function.
3273 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3276 silc_pkcs_private_key[_data]_set.
3278 * Made the password and public authentication more cleaner in
3279 server's protocol.c.
3281 * Removed historic and obsolete protocol `channel_auth' from
3282 both client and server.
3284 * Removed wrong way of sending command status messages from
3285 server to client in server's command.c. The old way violated
3286 protocol specification.
3288 Changes to silccore/silccommand.[ch]: removed
3289 silc_command_encode_status_payload -> not needed anymore,
3290 changed silc_command_encode_payload_va to accept extra
3291 argument on variable argument list. The argument type must
3292 now be provided to the function. Also, added new function:
3293 silc_command_encode_reply_payload_va which is same as
3294 normal command_encode_payload_va except command status type
3295 is provided as extra argument.
3297 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added ~./silc directory handling. The directory includes the
3300 public and private keys for the client.
3302 Added silc_client_check_silc_dir, silc_client_create_identifier
3303 and silc_client_load_keys.
3305 * Implemented SILC protocol compliant public key. Added public
3306 and private key saving to and loading from files.
3308 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3309 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3310 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3311 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3312 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3314 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3315 silc_pkcs_load_[public/private]_key.
3317 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Added silc_server_get_route (route.[ch]) to get connection
3320 data for the fastest route for given ID.
3322 * Implemented INVITE command on client and server. The command
3323 were re-defined in the SILC Protocol Specification and the
3324 implementation now complies with the specification.
3326 * Implemented PING command on client and server.
3328 * Implemented NAMES command on client and server. The server side
3329 supports currently only normal server not router server yet.
3330 Some changes to NAMES definition in SILC protocol specification.
3332 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Implemented LEAVE command on client and server.
3336 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3337 again. This change was made to the protocol as well. Server
3338 should not violate the protocol specification anymore.
3340 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3343 was tested. SOCKS4 was not but should work anyway.
