1 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * New web pages in the http://silc.pspt.fi. The pages was
8 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Implemented the [DenyConnectin] config section in the server.
11 Added silc_server_config_denied_conn to check whether incoming
12 connection is denied. Affected file silcd/serverconfig.[ch].
14 * Do not check the ports when checking the incoming configuration
15 data if the port is 0, meaning any. Affected file is
18 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Fixed buffer overflow in silc_string_compare in the file
21 lib/silcutil/silcutil.c.
23 * Fixed double free in silc_server_command_leave in the file
26 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Fixed the version checking in the server. Affected file is
31 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Fixed the configuration data fetching when accepting new
34 connections in the server. Affected file silcd/server.c.
36 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Added `sender_entry' argument to the function
39 silc_server_packet_relay_to_channel so that we can check
40 whether some destination actually belongs to the same route
41 the sender belongs (ie, we must not resend the packet to the
42 sender). Affected file silcd/packet_send.[ch].
44 * Added `servername' field to the SilcClientEntry in the server
45 to hold the name of the server where client is from. Affected
46 file is silcd/idlist.h.
48 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * Moved the channel message encrypting in the router betwen
51 router connections from silc_server_channel_message to the
52 silc_server_packet_relay_to_channel since we want to check
53 whether we have anybody channel before encrypting anything.
54 Affected files silcd/packet_[receive/send].c.
56 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
58 * Fixed the [AdminConnection] server config section to support
59 multiple entries. Affected file silcd/serverconfig.c.
61 * Added support into the server to check the validity of the
62 incoming connection before executing any KE or authentication
65 * The connection configuration is now saved to the KE and
66 connection auth protocol contexts and not fetched anymore in
67 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
69 * The local hosts listenning address and port is also resolved
70 now when starting the server. We want to have the socket object
71 to include the real address and port for the listener. Added
72 new function silc_net_check_local_by_sock into the files
73 lib/silcutil/silcnet.[ch].
75 * Fixed a broadcast bug in server -> do not broadcast if we
78 * Fixed a routing bug. Do not route broadcast packets ever.
79 Broadcast packets must be processed always and not routed since
80 they may be destined to some other host than yourself and thus
81 would get routed without no good reason. Affected file is
84 * Added function silc_server_config_is_primary_route to check
85 whether primary router connection has been configured (a router
86 configuration that we are initiating). If there is not, we
87 will assume that there is only two routers in the SILC network
88 and we will use the incoming router connection as our primary
89 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
91 * Changed the order of the broadcasting. Broadcast _after_ the
92 packet has been processed not before. Affected file is
95 * Fixed a [ClientConnection] parsing bug. The port was never
96 parsed correctly thus resulting to port 0. Affected file
99 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
100 argument and did not set the broadcast packet flag. Affected
101 file silcd/packet_send.c. Fixed same bug in the function
102 silc_server_send_notify as well.
104 * If we receive NEW_ID packet for our own ID in the server, ignore
107 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Removed the nickname from the Private Message Payload.
112 Updated the code and the protocol specs.
114 * Updated protocol specs for submitting to the IETF.
116 * Tweaked the Random Number Generator a bit. Affected file
117 lib/silccrypt/silcrng.c. Exported a new function
118 silc_rng_[global]_add_noise which can be used to add more
121 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Do not parse packets with different timeout when protocol
124 is active -> may cause problem with rekey. Affected file
127 * When server receives signoff notify it must not create
128 new channel key if the client is on any channels since the
129 sender of the signoff notify will create it.
131 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Added printing of error messages during SKE protocol from the
134 failure packet sent by server during SKE. Affected file
137 * Removed the client's failure_callback handling with timeout
138 and handle it immediately when received.
140 * The SKE library returned wrong type in SUCCESS and FAILURE
141 packets. They must be 32 bit MSB not 16 bit MSB.
143 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Ok, rewrote the logic of the re-key and now it seems to work.
146 I tested it on high traffic with frequent re-keys without
147 problems. Added hmac_receive (and renamed hmac to hmac_send)
148 in SilcClientConnection in lib/silcclient/client.h and
149 in SilcIDListData in silcd/idlist.h. Also, removed the
150 SilcPacketParserContext's cipher and hmac fields as they are
151 not needed anymore and actually caused some problems when
152 the ciphers and hmac's changed underneath the packet parser.
154 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * If re-key protocol is active then process the incoming packets
157 synchronously since we must assure that icoming packets encrypted
158 with the old key is processed before the new keys is set to
159 use. This is true other packets than for REKEY packets.
160 Affected file silcd/server.c. The same was done to client library
161 as well, affected file lib/silcclient/client.c.
163 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Fixed bug in client and server to accept the force send if
166 the packet is send from silc_[server/client]_packet_process
167 function. Otherwise the packets are never delivered, oops.
169 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Disable force sending of packets when REKEY protocol is active.
172 We must assure that no packet is sent directly when rekey is
173 performed. All packets must be sent through packet queue.
174 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
175 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
176 function is silc_[server/client]_packet_send_real to check
179 * Replaced the SIM paths from example config files to
180 /usr/local/modules. Also, make install creates now
181 /usr/local/silc/logs directory to hold all the SILC server
184 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Made the configure.in.pre work on Solaris. Patch by salo.
188 * Made all ciphers compatible with non-x86 machines. Defined
189 CBC mode macros into lib/silccrypt/ciphers_def.h.
191 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Fixed the make install.
195 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * When MAC computation fails the silc_packet_decrypt returned 0
198 even though it was supposed to return -1. Fixed this. The
199 affected file is lib/silccore/silcpacket.c.
201 * Do not replace the config files in /etc/silc (in make install)
202 if they already exist. Affected file ./Makefile.am.
204 * Do not send re-key packets immediately but through packet queue.
205 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
207 * Changed silc_net_check_host_by_sock to return FALSE if the
208 IP/DNS could not be resolved. Though, it returns the IP address
209 now even if it could not resolve it (but returns also FALSE).
210 Affected file lib/silcutil/silcnet.[ch].
212 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Added silc_pkcs_decode_identifier to decode the public key's
215 identifier. Affected file lib/silccrypt/silpkcs.[ch].
216 Added also silc_pkcs_free_identifier. Added also new context
217 SilcPublicKeyIdentifier.
219 * Added -S option to the silc client. It is used to dump the
220 contents of the specified public key file.
222 * Changed the PKCS api to return the public key length when
223 setting the public key.
225 * Fixed a fatal bug in the public and private key file loading.
226 Affected file lib/silccrypt/silcpkcs.c.
228 * Execute the packet parsing for client with zero (0) timeout
229 if the protocol is active. Affected file silcd/server.c.
231 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Made the key generation options to the silcd program. Added
234 -C option, equivalent to client's option.
236 * Added new [ServerKeys] config section to the server. It
237 configures the server's public and private key.
239 * Defined generic Public Key Payload into the protocol
240 specification to send specific type of public keys and
243 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
244 public key or certificate.
246 * Implemented the GETKEY command to the server and to the
247 client library and on user interface.
249 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Made preliminary `make install' work.
253 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Added SilcServerRekey context into silcd/idlist.h.
257 * Added the PFS support as defined in the specification to the
258 SKE protocol. Affected files lib/silcske/*.c.
260 * Added `ske_group' field to the SilcServerRekey context to hold
261 the number of the SKE group that is used with PFS in re-key.
262 Affected file silcd/idlist.h.
264 * Added PFS re-key support to the server. Affected file is
267 * Added silc_protocol_cancel to cancel execution of the next
268 state of the protocol. Affected file is
269 lib/silccore/silcprotocol.[ch].
271 * Added the re-key support with and without PFS to the client
272 library. Re-key is performed once in an hour, by default.
274 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
275 Added silc_client_rekey_callback and silc_client_rekey_final.
276 Affected files are lib/silcclient/protocol.[ch] and
277 lib/silcclient/client.[ch].
279 * Removed the `hmac_key' and `hmac_key_len' fields from the
280 SilcClientConnection structure; not needed. Affected file is
281 lib/silcclient/client.h.
285 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Do not ask whether user wants to use the negotiated private key
288 for private messages, just use it. Affected file is
289 silc/local_command.c.
291 * Added `send_enc_key' and `enc_key_len' fields to the
292 SilcIDListData structure since they are needed in the re-key
293 phase. Affected file is silcd/idlist.[ch].
295 * Implemented the simple re-key protocol into the server.
296 Affected files silcd/server.c and silcd/protocol.[ch]. The
297 re-key will be performed once in an hour, by default.
299 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
300 Added silc_server_rekey, silc_server_rekey_callback and
301 silc_server_rekey_final.
303 * Removed Tunneled flag from the protocol. Updated the code
304 and the specifications.
306 * Adde `pfs' field to the SilcIDListData to indicate whether
307 the PFS is to be performed in the re-key. Affected file is
310 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
313 int64 of at least the xintXX size. If void * is less that 4
314 bytes uint32 * will be used. Defined bool as boolean.
316 * Changed _ALL_ unsigned long and unsigned int to uint32,
317 unsgined short to uint16 in the source tree.
319 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
320 not handle clients that has entry->data.registered == FALSE.
321 They are not in the network anymore. Affected file is
324 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Implemented the sending of the SERVER_SIGNOFF notify in the
327 server. Affected file is silcd/server.c.
329 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
330 Added also silc_notify_payload_encode_args into the
331 lib/silccore/silcnotify.[ch].
333 * Implemented ther SERVER_SIGNOFF notify handling in the server.
334 Affected file silcd/packet_receive.c.
336 * Implemented the SERVER_SIGNOFF notify handling in the client
337 library. Affected file lib/silcclient/client_notify.c. Also,
338 implemnted the printing of the SERVER_SIGNOFF info to the
339 application. Affected file silc/client_ops.c.
341 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
342 if the deleting was successful. Affected file silcd/idlist.[ch].
344 * Added support for public key authentication in the connection
345 authentication protocol in the client library. Affected file
346 lib/silcclient/protocol.c.
348 * Changed the server's silc_idlist_get_clients_by_* interface
349 to support already allocated array so that new entries may be
350 added to pre-allocated array. Affected file silcd/idlist.[ch].
351 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
354 * All command reply functions in the server now calls the
355 pending command callback even if error occured. This way the
356 error will be delivered to the client as well. Affected files
357 silcd/command.c and silcd/command_reply.c.
359 * Fixed INFO command to return local server's info if no server
360 was provided. Affected file lib/silcclient/command.c.
362 * Removed RESTART command for good. Updated the code and the
365 * Rewrote parts of the task system. It is a bit simpler now.
366 Removed unsued task priorities. The affected files are
367 lib/silcutil/silctask.[ch].
369 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Moved the USERS printing from the library to the application.
372 Affected files lib/silcclient/command.c and silc/client_ops.c.
374 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * Added channel key re-key support. The re-key is perfomed
379 only by the router and is done once in an hour. Added `rekey'
380 field to the SilcChannelEntry in the server. Affected files
381 silcd/server.c and silcd/idlist.h.
383 * Added silc_task_unregister_by_context into the file
384 lib/silcutil/silctask.[ch].
386 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Added SILC_UMODE_GONE mode to indicate when the client is not
389 present in the SILC network. Added also support to the local
390 command AWAY that will set this mode. Added support of showing
391 "xxx is gone" in WHOIS command. The USERS command shows the
394 * Fixed setting server and router operator privileges in the
395 server's UMODE command. Affected file silcd/command.c.
397 * Merged the SKE KE1 and KE2 payloads into one payload. The
398 new KE payload is equivalent to the old KE2 payload.
400 Cleaned up the SKE Start Payload parsing. It now uses the
401 simple buffer unformatting to do the parsing. A lot faster
404 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
405 to the SKE that is used to indicate whether both of the SKE
406 parties should perform authentication. By default only the
407 responder performs authentication. By setting this flag also
408 the initiator must do authentication. By default it is unset
409 since in normal SKE case, client to server connection, only
410 the responder should do authentication. When doing SKE between
411 two clients both should perform authentication. Updated the
412 code and the protocol specs.
414 * A little fix to IDENTIFY command in the server. Search the
415 client first by hash not nickname. Affected file is
418 * Fixed the silc_client_close_connection to support closing
419 the client to client connections wihtout deleting too much
420 data. Affected file lib/silcclient/client.c.
422 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
423 are received if protocol used to be active but is not anymore
424 the application would crash due to NULL pointer dereference.
425 Affected files silcd/server.c and lib/silcclient/client.c.
427 * Added `hash' field to the SilcClientConnection to include
428 the hash function negotiated in the SKE protocol.
430 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
431 to set the channel founder authentication data. A client can
432 claim the founder rights later by providing the authentication
433 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
434 This way the channel founder can regain the channel founder
435 privileges even it is left the channel. This works only on
436 local server and the client must be connected to the same
437 server to be able to regain the founder rights. Updated the
438 protocol specs accordingly.
440 Added support to the CMODE command in the client to set the
441 founder auth data. Read the README to see how to set it.
443 Added support to the CUMODE command to claim the founder
444 rights. Read the README to see how to do it.
446 Added support for the founder authentication to the Channel
447 Entry in the server. Affected file silcd/idlist.h.
449 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
450 server's CMODE command. Affected file silcd/command.c.
452 * Added the following new functions into lib/silccore/silcauth.[ch]:
453 silc_auth_get_method and silc_auth_get_data.
455 * The server now saves the remote hosts public key to the
456 SilcIDListData pointer. Affected file silcd/protocol.c.
458 * The normal server now does not remove the channel entry from
459 the cache if the founder authentication data is set. It used
460 to remove it if the founder was the last one on the channel on
461 the server and left the channel. The auth data is saved and
462 if the channel is re-joined later the old entry is used with
463 the old auth data. Affected files silcd/command_reply.c and
466 * Removed the `pkcs' field from the SilcIDListData structure
467 in the server; it is not used. Affected file silcd/idlist.h.
469 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Fixed packet processing on slow links. Partial packets were
472 never re-processed because the incoming data buffer was cleared
473 by the application. Application must not directly clear the
474 sock->inbuf, the packet processing routines handle it. Fixed
475 this in client library and in server.
477 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Fixed the WHOIS and IDENTIFY send reply function to really
480 check whether to send list or just one entry. Affected file
483 * Cleaned up the LEAVE command's channel key distribution. The
484 affected file silcd/command.c.
486 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
487 can enforce the channel mode as well. In that case the ID
488 includes the ID of the server. The code now enforces the
489 mode change if the router have different mode than the server.
491 * The notify client operation with CMODE_CHANGE notify can now
492 return NULL client_entry pointer if the CMODE was not changed
493 by client. Application must check for this.
495 * Added <Server ID> argument to INFO command to support server
496 info fetching by Server ID.
498 * Added silc_server_announce_get_channel_users to get assembled
499 packets of channel users of the specified channel. Affected
500 file silcd/server.[ch].
502 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
503 was freed underneath the ID Cache.
505 * Re-announce clients when the server received CHANNEL_CHANGE
506 notify from the router. Affected file silcd/packet_send.c.
508 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
511 crashed since it did not handle the fact that there is no cipher
512 called "3" and didn't check the error condition. Now fixed.
514 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
515 flag. It can be used to send message requests.
517 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Implemented the RESTART command in the client.
521 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
522 notice type messages. Added notice printing to the user
525 * The channel keys are not re-generated if the channel's mode
526 is PRIVKEY, ie private key on the channel exists. Affected
527 files silcd/server.c and silcd/command.c.
529 * Fixed a little bug in channel message delivery when channel
530 private keys are set in the server. Affected file is
533 * Changed the setting on channel->on_channel = TRUE from the
534 silc_client_save_channel_key to the JOIN command reply. The
535 key payload is not received if the private channel key is set.
536 Affected file lib/silcclient/command_reply.c and the
537 lib/silcclient/client_channel.c.
539 * When the CMODE_CHANGE notify is sent and the channel private
540 key mode is removed the channel key must be re-generated in
541 other cells as well. Added this support for the router in the
542 silcd/packet_receive.c.
544 * Added new local command NOTICE to send notice message on
545 channel. Affected file silc/local_command.[ch].
547 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Added new local command ME to the client. It is used to send
550 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
551 some action. Affected file silc/local_command.[ch].
553 * Changed channel_message and private_message client operations
554 to deliver the message flags to the application. Added also
555 the `flags' arguments to the silc_client_send_channel_message
556 and silc_client_send_private_message functions. Affected file
559 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
561 * Redefined the Private Message Payload to support private message
562 keys and to support the new private message flags. Updated
563 the protocol specs. Flags makes it possible to have for example
566 * Added new type SilcPrivateMessagePayload and defined an API
567 for it in the lib/silcclient/silcprivate.[ch].
569 * Tested private message private keys successfully. Tested the
570 private message key set, unset and list commands with the new
573 * Redefined the Channel Message Payload to include the channel
574 message flags (equal with private message flags) to support
575 for example CTCP style messages.
577 * Defined some of the message (for channel and private message)
578 flags. Updated the protocol specs and added the flags to the
579 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
581 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added SilcKeyAgreementStatus type to the key agreement routines
584 to indicate the current status and error if one occured.
585 The status types are defined in the lib/silcclient/silcapi.h.
587 * Added new local command KEY that is used to set and unset private
588 keys for channels, set and unset private keys for private messages
589 with remote clients and to send key agreement requests and
590 negotiate the key agreement protocol with remote client. The
591 key agreement is supported only to negotiate private message keys,
592 it currently cannot be used to negotiate private keys for channels,
593 as it is not convenient for that purpose.
595 * Fixed a minor pending callback setting bug in the function
596 silc_client_get_client_by_id_resolve, now the function works.
597 Affected file lib/silcclient/idlist.c.
599 * Added function silc_net_get_local_port to get local bound
600 port by socket. Added to lib/silcutil/silcnet.[ch].
602 * Added `sockets' and `sockets_count' fields to the SilcClient
603 object. They hold the sockets of the listenning sockets in
604 the client. Listenning sockets may be for example the key
605 agreement server. Affected file lib/silcclient/client.[ch].
606 Added functions the silc_client_add_socket and the
607 silc_client_del_socket. They are exported to the application
610 * Added ~./silc/clientkeys to support other client's public keys.
612 * Renamed verify_server_key client operation to verify_public_key
613 and added one argument to indicate the type of the connection
614 (server, client etc.).
616 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Added silc_server_connection_auth_request to handle the
619 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
620 silcd/packet_receive.[ch].
622 * Added silc_server_send_connection_auth_request into the
623 silcd/packet_send.c to send the connection auth request packet.
625 * Cleaned up the silcd/protocol.c a bit and fixed some memory
628 * Fixed the public key authentication in responder side in the
629 server. The `auth_data' pointer includes the SilcPublicKey
630 not the path to the public key. Affected file silcd/protocol.c.
632 * Implemented the public key authentication in the initiator side
633 in the server. Affected file silcd/protocol.c.
635 * Removed the [RedirectClient] config section from the server
636 configuration. Is not needed and I don't want to implement it.
638 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Cleaned up the CMODE command in the server. It now works
641 correctly and supports all the modes defined in the protocol.
642 Affected file is silcd/command.c.
644 * Added `hmac_name' field to the SilcChannelEntry in the server
645 to hold the default HMAC of the channel. It can be set when
646 creating the channel (with JOIN command). Affected files
649 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
650 type to indicate the change of the current cipher and hmac
651 on the channel. Client can safely ignore the <cipher> argument
652 (if it chooses to do so) since the CHANNEL_KEY packet will
653 force the channel key change anyway. The <hmac> argument is
654 important since the client is responsible of setting the new
655 HMAC and the hmac key into use.
657 * Fixed the CMODE command in the client library as well.
659 * Tested CMODE command in router environment successfully.
661 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Show the version of the remote client (or server) when connecting
664 to the server. It is logged to the log file. Affected file
667 * Fixed the KILLED notify handling in the client library. The
668 client must be removed from all channels when receiving the
671 Also, do not remove the client entry when giving the KILL
672 command but when the KILLED notify is received.
674 * Removed silc_idlist_find_client_by_nickname from the server.
675 Not needed anymore. Affected files silcd/idlist.[ch].
677 * Implemented the CHANNEL_CHANGE notify type handling to the
678 server. Affected file silcd/server.c.
682 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

685 notify between routers.
687 * Implemented the INVITE command correctly to the server.
689 * Implemented the INVITE notify type handling in the server.
691 * Implemented the INVITE command to the client library and on the
694 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Added function silc_server_get_client_resolve to find the
697 client entry by ID from all ID lists and then resolve it
698 (using WHOIS) if it cannot be found. Affected file is
701 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Implemented the BAN command to the client library.
705 * The JOIN command in the server now checks the invite list
708 * Changed the silc_command_reply_payload_encode_va and the
709 silc_command_payload_encode_va to support that if argument is
710 NULL it ignores and checks the next argument. Affected file
711 lib/silccore/silccommand.c.
713 * Added silc_server_send_notify_ban to send the BAN notify
714 type between routers.
716 * Chaned the silc_notify_payload_encode to support that if
717 argument is NULL it ignores and checks the next argument.
718 Affected file lib/silccore/silcnotify.c.
720 * Tested ban lists in router environment successfully.
722 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Implemented BAN command to the server, in silcd/command.[ch].
726 * Removed the BAN and INVITE_LIST modes from the CMODE command
729 * Added function silc_string_match to regex match two strings.
730 Affected files lib/silcutil/silcutil.[ch].
732 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Redefined parts of the SilcChannelEntry in the server to support
735 the new ban and invite lists.
737 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Redefined the INVITE command. The same command can be used to
740 invite individuals to the channel but also to manage the invite
741 list of the channel (to add to and remove from the invite list).
742 Updated the protocol specs.
744 * Added new command SILC_COMMAND_BAN that can be used to manage
745 the ban list of the channel. Updated the protocol specs.
747 * Removed the channel modes: the SILC_CMODE_BAN and the
748 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
749 in the CMODE command. The equivalent features are now available
750 using INVITE and BAN commands. Updated the protocol specs.
752 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
753 in the network about change in the current ban list. The notify
754 type is not used by the client.
756 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
757 support the invite lists.
759 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Added new function silc_string_regexify that converts string
762 including wildcard characters into regex string that can
763 be used by the GNU regex library. Added into the file
764 lib/silcutil/silcutil.[ch].
766 Added silc_string_regex_combine to combine to regex strings
767 into one so that they can be used as one regex string by
768 the GNU regex library. Added into the file
769 lib/silcutil/silcutil.[ch].
771 Added silc_string_regex_match to match two strings. It returns
772 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
774 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Imported GNU regex to the soruce tree into lib/contrib.
777 Fixed some compiler warning from the regex.c.
779 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Fixed MOTD command in the server to work in router environment.
783 * Fixed the MOTD command in the client library to support
784 the server argument in the command.
786 * Added `nickname_len' argument to the silc_idlist_add_client
787 in the server, as the `nickname' argument may be binary data
790 * Added silc_idlist_get_channels to return all channels from
793 * Implemented LIST command to the server. Affected file is
796 * Implemented the LIST command to the client library and on the
799 * Added [<user count>] argument to the LIST command reply.
800 With private channels the user count is not shown.
802 * Updated TODO and README.
804 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * The client entry's data.registered must be TRUE even with
807 global client entry on global client list. The data.registered
808 is used to check whether the client is anymore in the network,
809 for example with WHOWAS command so it must be valid.
811 * Fixed the WHOWAS command in the server. It now actually works
812 in router environment. Added function into silcd/command_reply.c
813 silc_server_command_reply_whowas_save.
815 * Added silc_idlist_purge function to the silcd/idlist.c
816 to periodically purge the ID Cache.
818 * Fixed INFO command in the server. It works now in router
819 environment. Added <server name> argument to the INFO command
820 reply. Updated the protocol specs.
822 * Fixed minor bug in silc_idcache_purge to not purge if the
823 expire value is zero.
825 * Fixed various bugs in WHOIS and IDENTIFY command handling as
826 they were buggy because of the WHOWAS information.
828 * Fixed local command MSG to handle the async resolving of
829 the remote client properly. It used to fail the first MSG.
830 Affected file silc/local_command.c.
832 * Added `data_len' field to SilcIDCache context.
834 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Update TODO. Todo in commands in the server.
838 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
841 used by routers as broadcast packet to inform other routers
842 about the changed user mode.
844 Implemented the notify handling in the server. Affected file is
845 silcd/packet_receive.c. Added the function
846 silc_server_send_notify_umode to the silcd/packet_send.[ch].
848 * Added new generic Channel Payload and deprecated the New Channel
849 Payload. The New Channel Payload is now the generic Channel
852 * Added new argument `mode' to the silc_server_send_new_channel
853 as it is required in the Channel Payload now.
855 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
856 and created a new and real SilChannelPayload to represent the
857 new generic Channel Payload. Implemented the encode/decode
858 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
860 * Added silc_server_get_client_channel_list to return the list
861 of channels the client has joined for WHOIS command reply.
862 Affected file silcd/server.[ch].
864 * Implemented the channel list sending in the WHOIS command reply
865 in server and in the client.
867 Implemented the channel list displaying on the user interface
868 as well. Affected file silc/client_ops.c.
870 * Added silc_channel_payload_parse_list to parse list of Channel
871 Payloads. It returns SilcDList list of SilcChannelPayloads.
872 Client for example can use this function to parse the list of
873 channels it receives in the WHOIS command reply. The caller
874 must free the list by calling silc_channel_payload_list_free.
875 Affected files lib/silccore/silcchannel.[ch].
877 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Added one new argument <user mode> to the WHOIS command reply
880 to return the mode of the user in SILC. Updated the protocol
883 Implemented it to the server and client.
885 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Fixed the mode printing on the user interface on joining.
888 Affected file silc/client_ops.c.
890 * Implemented the UMODE command and user modes in general to the
891 client library and to the user interface.
893 * Implemented the UMODE command to the server.
895 * The server now sends UNKNOWN_COMMAND error status if client sends
896 unknown command. Affected file silcd/command.c.
898 * All server commands now handle the command identifier the right
899 way when sending the command reply to the client. The client can
900 use to identify the command replies with the identifier.
902 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Added silc_server_get_client_route to resolve the route to
905 the client indicated by the client ID. Affected file is
908 * Added silc_server_relay_packet as general function to relay
909 packet to arbitrary destination. This deprecates functions
910 like _send_private_message_key, _relay_notify etc. Affected
911 file is silcd/packet_send.[ch].
913 Removed silc_server_send_key_agreement,
914 silc_server_send_private_message_key and
915 silc_server_packet_relay_notify functions from the file
916 silcd/packet_send.[ch].
920 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
921 server. Affected file silcd/packet_receive.[ch].
923 * Implemented the KILL command to the client. Implemented the
924 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
925 Affected files lib/silcclient/command[_reply].c and
926 lib/silcclient/client_notify.c. Implemented the KILL notify
927 printing in the user inteface.
929 * Fixed a lot silc_parse_nick memory leaks from the client
930 library in the file lib/silcclient/command.c.
932 * Changed the silc_server_send_notify_on_channels's `sender'
933 argument from SilcSocketConnection to SilcClientEntry to
934 check the sender as entry and not as connection object and not
935 to send to the client provided as argument. The affected file
936 is silcd/packet_send.[ch].
938 * The notify packets that are destined directly to the client used
939 to not to be processed by the server. Now changed that and the
940 server processes all notify packets. After relaying the packet
941 to the client the notify packet is processed in the server.
943 * The silc_server_free_client_data now checks whether there is
944 pending outgoing traffic for the client and purges the data to
945 the network before removing the client entry.
947 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
950 an client is killed from the SILC Network. Updated the protocol
953 Added new function silc_server_send_notify_killed to the
954 silcd/packet_send.[ch].
956 * Added function silc_server_packet_relay_notify to relay notify
957 packets that are destined directly to a client. In this case
958 the server does not process the notify packets but merely relays
959 it to the client. Affected file silcd/packet_send.[ch].
961 Added also silc_server_packet_process_relay_notify to check
962 whereto relay the notify. Affected file is
963 silcd/packet_receive.[ch].
965 * Implemented the KILL command to the server.
969 * Added the backup schema desgined last fall to the protocol
970 specs for everyone to see. The specification is in the
971 *-spec-xx.txt draft and the packet type definitions for the
972 backup routers is in *-pp-xx.txt draft. Thusly, added also
973 new packet type SILC_PACKET_CELL_ROUTERS.
975 * A big security problem in the implementation discovered. The
976 signoff of an client did not cause new channel key generation
977 which it of course should've done. The channel keys must be
978 always re-generated when client leaves (or signoffs) the channel.
979 The silc_server_remove_from_channels funtion now handles
980 the channel key re-generation.
982 * Added `sender' argument to the silc_server_send_notify_on_channels
983 to not to send the client provided as argument. Affected file
984 silcd/packet_send.[ch].
986 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Implemented OPER and SILCOPER commands into the server and
991 * Added silc_auth_verify and silc_auth_verify_data to verify
992 the authentication directly from the authentication payload.
993 It supports verifying both passphrase and public key based
994 authentication. Affected file lib/silccore/silcauth.[ch].
996 * Added `hash' field to the SilcIDListData structure. It is the
997 hash negotiated in the SKE protocol. Affected file is
1000 * Slight redesigning of the SilcAuthPayload handling routines.
1001 Do not send SilcPKCS but SilcPublicKey as argument.
1003 * Implemented the public key authentication support to the
1004 serverconfig. The public key is loaded from the provided path
1005 and saved as authentication data to void * pointer. Thus,
1006 changed the unsigned char *auth_data to void *auth_data;
1008 * Fixed SHUTDOWN command to send the reply before the server
1009 is shutdown. :) Affected file silcd/command.c.
1011 * Fixed fatal bug in CONNECT command. The hostname was invalid
1012 memory and server crashed. Affected file silcd/command.c.
1014 * Fixed fatal bug in CLOSE command. The server_entry became
1015 invalid but was referenced later in the command. Affected file
1018 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Fixed fatal bug in failure packet handling. Server ignored
1021 the failure and thus crashed when it came.
1025 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1028 that the command may be executed only once in (about) 2 seconds.
1029 The old SILC_CF_LAG flag is same but allows command bursts up
1030 to five before limiting.
1032 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1033 server code. Various commands now includes the CF_LAG_STRICT
1034 flag to disallow any kind of miss-use of the command.
1036 * Fixed the silc_buffer_unformat to not to allocate any data
1037 if the length of the data is zero. It used to allocate the
1038 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1040 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Changed the format of AdminConnection configuration section
1043 in the server. Added username of the admin to the format.
1044 Affected files silcd/serverconfig.[ch].
1046 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1047 to return admin configuration data by host, username and/or
1050 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Implemented WHOWAS command to the server. Added the functions:
1054 silc_server_command_whowas_parse,
1055 silc_server_command_whowas_send_reply,
1056 silc_server_command_whowas_from_client and
1057 silc_server_command_whowas_from_server
1059 * Added <Client ID> argument to the WHOWAS command reply. Updated
1060 the protocol specs accordingly.
1062 * Implemented WHOWAS command and command_reply to the client
1065 Implemented the WHOWAS printing on the user interface.
1067 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added new argument to the WHOWAS command reply, the real name.
1070 It is an optional argument. Updated the protocol specs.
1072 * Added SilcIDCacheDestructor callback that is registered when
1073 the SilcIDCache is allocated. The callback is called when
1074 an cache entry in the ID Cache expires, or is purged from the
1075 cache. Added into lib/silccore/idcache.[ch].
1077 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1078 to destruct the client entries when the cache entry expires.
1079 Other ID Cache's in server and in the client library ignores
1082 * If the ID Cache entry's `expire' field is zero then the entry
1083 never expires. Added boolean `expire' argument to the
1084 silc_idcache_add function in the lib/silccore/idcache.[ch].
1085 If it is TRUE the default expiry value is used.
1087 * Added silc_server_free_client_data_timeout that is registered
1088 when client disconnects. By default for 5 minutes we preserve
1089 the client entry for history - for WHOWAS command.
1091 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Added support to the server to enforce that commands are not
1094 executed more than once in 2 seconds. If server receives
1095 commands from client more frequently, timeout is registered
1096 to process the commands. Affected file silcd/command.c.
1097 Added new function silc_server_command_process_timeout.
1099 * Changed NICK_NOTIFY handling in client library to check that
1100 if the client's nickname was changed, so there is no need to
1101 resolve anything from the server.
1103 * Removed error printing from the WHOIS and IDENTIFY commands.
1104 If error occurs then it is ignored silently in the client library.
1105 The application, however, may map the received error to
1106 human readable error string. The application currently maps
1107 the NO_SUCH_NICKNAME error to string.
1109 * Made the command status message public to the application. Moved
1110 them from lib/silcclient/command_reply.c to
1111 lib/silcclient/command_reply.h. The application can map the
1112 received command status to the string with the
1113 silc_client_command_status_message function.
1115 * Added check to the server to check that client's ID is same
1116 as the Source ID in the packet the client sent. They must
1119 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Added dist-bzip hook to the Makefile.am to make bzip2
1122 compressed distributions.
1124 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Server now enforces the maximum length for the nickname and
1127 the channel as protocol specification dictates. 128 bytes for
1128 nickname and 256 bytes for channel name.
1130 * Moved the WHOIS printing to the application. The client libary
1131 does not print out the WHOIS information anymore, the application
1132 must do it. Renamed silc_client_command_reply_whois_print to
1133 the silc_client_command_reply_whois_save.
1135 The client's idle time is also sent to the application now, and
1136 the idle is shown on screen.
1138 * Added silc_client_command_reply_identify_save to save the
1139 received IDENTIFY entries.
1141 * Do not check for channel private keys in message sending and
1142 reception if the channel does not have the PRIVKEY mode set.
1143 Affected file lib/silclient/client_channel.c.
1145 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1148 just surfaced after chaning the JOIN procedure.
1150 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Added silc_client_get_clients_by_list to get client entries
1153 from Client ID list, that is returned for example by JOIN
1154 and USERS command replies. The application should use this
1155 function for example when JOIN command reply is received to
1156 resolve the clients already on the channel (library does not
1157 do that anymore as USERS command reply is not used in the JOIN
1158 procedure anymore). Affected files lib/silcclient/silcapi.h and
1159 lib/silcclient/idlist.c.
1161 * JOIN command reply and USERS command reply returns now SilcBuffer
1162 pointers instead of unsigned char pointers when returning
1163 the client list and mode list.
1165 * Added <Client ID> argument to the JOIN command reply, mainly
1166 for the server to identify for which client the command was
1167 originally sent. Updated protocol specs accordingly.
1169 * Added SilcDlist private_key pointer to the SilcChannelEntry
1170 in the client to support the channel private keys. Affected
1171 file is lib/silcclient/idlist.h.
1173 * Added SilcChannelPrivateKey argument to the function
1174 silc_client_send_channel_message so that application can choose
1175 to use specific private ke if it wants to. If it is not provided,
1176 the normal channel key is used, unless private keys are set.
1177 In this case the first (key that was added first) is used
1178 as the encryption key.
1180 * Implemented the support for channel private key handling.
1181 Implemented the following functions:
1183 silc_client_add_channel_private_key,
1184 silc_client_del_channel_private_keys,
1185 silc_client_del_channel_private_key,
1186 silc_client_list_channel_private_keys and
1187 silc_client_free_channel_private_keys
1189 Affected file lib/silcclient/client_channel.c.
1191 * Added the support for the private keys in the channel message
1192 sending and encryption and in the message reception and
1193 decryption. Affected funtions are
1194 silc_client_send_channel_message and silc_client_channel_message.
1196 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1198 * Added SKE's key verify callback to the client library's
1199 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1201 * Removed the statement that server (or router) must send USERS
1202 command reply when joining to the channel so that the client
1203 knows who are on the channel. Instead, the client list and
1204 client's mode list is now sent in the JOIN command reply to the
1205 client who joined channel. This is better solution.
1207 * Added function silc_server_get_users_on_channel and function
1208 silc_server_save_users_on_channel to the silcd/server.[ch].
1210 * Removed function silc_server_command_send_users from the
1213 * Do not show topic on the client library anymore. The topic is
1214 sent in the command reply notify to the application and the
1215 application must show the topic now.
1217 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Added client searching by nickname hash into the IDENTIFY and
1220 WHOIS commands in the server as they were clearly missing from
1221 them. Affected file is silcd/command.c.
1223 * Fixed a bug in private message receiving in the client library.
1224 The remote ID was freed and it wasn't supposed, now it is
1227 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Minor fix to the channel payload; allocate the data area, as it
1230 needs to be of specific length.
1232 * If the key agreement port is zero then the operating
1233 system will define the bound port. Affected files are
1234 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1236 * Added new function silc_channel_payload_decrypt into the file
1237 lib/silccore/silcchannel.[ch].
1239 * Moved the channel message etc, check from silc_packet_decrypt
1240 to applications. The library calls now a generic
1241 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1242 when the packet is either normal or special. This was done to
1243 allow more wide range of checking that was not allowed when
1244 the code was in library. Now applications can do virtually any
1245 checks to the packet and return to the library the decision how
1246 the packet should be processed. Affected files are
1247 lib/silccore/silcpacket.[ch].
1249 Added silc_server_packet_decrypt_check to the server and
1250 silc_client_packet_decrypt_check to the client library.
1252 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1253 to send with specified source and destination information.
1255 * Channel message delivery between routers was broken after the
1256 channel key distribution was fixed earlier. The channel key
1257 was used be to distributed to other routers as well which is not
1258 allowed by the protocol. Now this is fixed and channel keys
1259 really are cell specific and the channel message delivery between
1260 routers comply with the protocol specification.
1262 * Fixed various commands in server to check also the global list
1263 for the channel entry and not just the local list. The affected
1264 file silcd/command.c.
1266 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Added assert()s to buffer formatting and unformatting routines
1269 to assert (if --enable-debug) when error occurs. Affected
1270 file: lib/silcutil/silcbuffmt.c.
1272 * Changed to auto-reconnect to check whether the remote host is
1273 router and register the re-connect timeout if it is. It used
1274 to check that whether we are normal server, but router must do
1275 auto-reconnect with another router as well. Affected file
1278 * Removed the [<key len>] option from CMODE command as the cipher
1279 name decides the key length, nowadays. See the defined ciphers
1280 from the protocol specification.
1282 * Added [<hmac>] option to the CMODE command to define the HMAC
1283 for the channel. Added SILC_CMODE_HMAC channel mode.
1285 * Added [<hmac>] option for the JOIN command so that user can
1286 select which HMAC is used to compute the MACs of the channel
1289 * Added Hmac field to the Channel Message Payload. The integrity
1290 of plaintext channel messages are now protected by computing
1291 MAC of the message and attaching the MAC to the payload. The
1292 MAC is encrypted. Now, it is clear that this causes some
1293 overhead to the size of the packet but rationale for this is that
1294 now the receiver can verify whether the channel message decrypted
1295 correctly and also when private keys are set for the channel the
1296 receiver can decrypt the packet with several keys and check from
1297 the MAC which key decrypted the message correctly.
1299 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1300 lib/silccrypt/silccipher.[ch].
1302 * Added silc_hash_len to return the digest length into the
1303 lib/silcrypt/silchash.[ch].
1305 * Rewrote parts of Silc Channel Payload interface in the
1306 lib/silccore/silcchannel.[ch]. The encode function now also
1307 encrypts the packet and parse function decrypts it.
1309 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Fixed a minor formatting bug in the SKE's key material processing.
1312 It actually might have processed the keys wrong way resulting
1315 * Redefined the mandatory HMAC algorithms and added new algorithms.
1316 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1317 and hmac-md5 truncated to 96 bits. The mandatory is now
1318 hmac-sha1-96. Rest are optional (including the one that used
1319 to be mandatory). Rationale for this is that the truncated HMAC
1320 length is sufficient from security point of view and can actually
1321 make the attack against the HMAC harder. Also, the truncated
1322 HMAC causes less overhead to the packets. See the RFC2104 for
1325 * Added new [hmac] configuration section. The SKE used to use
1326 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1327 is of course wrong. The official names that must be proposed in
1328 the SKE are the ones defined in the protocol specification
1329 (hmac-sha1-96 for example). The user can configure any hmac
1330 using any hash function configured in the [hash] section. At
1331 least, the mandatory must be configured.
1333 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1335 * Added HMAC list to the SKE proposal list. It has now both
1336 hash algorithm list and HMAC list. This makes the protocol
1337 incompatible with previous versions. The SKE now seems to work
1338 the way it is supposed to work, for the first time actually.
1340 * Defined plain Hash algorithms to the protocol specification.
1343 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Implemented support for key agreement packets into the server.
1346 Added functions silc_server_key_agreement and
1347 silc_server_send_key_agreement. Other than these functions,
1348 server has nothing to do with this packet.
1350 * Added support for private message key packets into the server.
1351 Added functions silc_server_private_message_key and
1352 silc_server_send_private_message_key.
1356 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1357 called in the protocol's final callback instead in the END
1358 protocol state. This makes a little more sense and in the same
1359 time in client we can use the same protocol routines for normal
1360 key exchange and to key agreement packet handling as well.
1362 * Added to both client's and server's KE protocol context the
1363 SilcSKEKeyMaterial pointer to save the key material. We will
1364 bring the key material to the protocol's final callback by doing
1365 this. The final callback must free the key material.
1367 * Added SKE's packet_send callback into client's KE protocol
1368 context so that the caller can choose what packet sending function
1369 is used. This way we can use different packet sending when
1370 doing normal SKE when doing key agreement packet handling (in
1371 the key agreement packet handling we do not want to encrypt
1374 * Implemented the responder side of the key agreement routines
1375 in the client. The client can now bind to specified port and
1376 accept incoming key negotiation. The key material is passed
1377 to the application after the protocol is over.
1379 * Implemented the processing of incoming Key Agreement packet
1380 in the client. Added function silc_client_key_agreement to
1383 * Implemented the intiator side of the key agreement routines
1384 in the client. The client can now initiate key agreement with
1385 another remote client. The key material is passed to the
1386 application after the protocol is over.
1388 * Created client_keyagr.c to include all the key agreement
1391 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1392 SILC_TASK_CALLBACK except that it is not static.
1394 * Created client_notify.c and moved the Notify packet handling
1395 from the client.[ch] into that file.
1397 * Created client_prvmsg.c and moved all private message and
1398 private message key routines from the client.[ch] into that file.
1400 * Create client_channel.c and moved all channel message and
1401 channel private key routines from the client.[ch] into that file.
1403 * Changed silc_client_get_client_by_id_resolve to resolve with
1404 WHOIS command instead of IDENTIFY command, in the file
1405 lib/silclient/idlist.c.
1407 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Implemented the SKE's responder side to the Client library.
1411 * When FAILURE is received to the protocol do not trust it
1412 blindly. Register a timeout to wait whether the remote closes
1413 the connection as it should do it, only after that process the
1414 actual failure. This was changed to both client and server.
1416 * Added client_internal.h to include some of the structures
1417 there instead of client.h in lib/silcclient/.
1419 * Added function silc_task_unregister_by_callback to unregister
1420 timeouts by the callback function.
1422 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Some "Incomplete WHOIS info" errors has been appearing on the
1425 log files. Took away the entry->userinfo check from WHOIS
1426 reply sending. The entry->userinfo is now " " if client did not
1427 provide one. I thought this was fixed earlier but something
1428 is wrong still. Let's see if the error still appears.
1430 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1432 * Fixed a minor bug in the login when the channel key is
1433 re-generated in the server. It used to generate the key in
1434 wrong order and thus caused problems in the channel traffic.
1436 * Fixed a minor bug in channel key distsribution after
1437 KICK command. The key was not sent to the router even though
1440 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Added silc_ske_process_key_material_data as generic routine
1443 to process any key material as the SILC protocol dictates. The
1444 function is used by the actual SKE library but can be used by
1445 applications as well. This relates to the private message keys
1446 and the channel private keys since they must be processed the
1447 same way the normal SILC session keys. The protocol dictates
1448 this. Affected files: lib/silcske/silcske.[ch].
1450 Added also silc_ske_free_key_material to free the
1451 SilcSKEKeyMaterial structure.
1453 * Defined silc_cipher_set_key function to set the key for
1454 cipher without using the object's method function. The affected
1455 files: lib/silccrypt/silccipher.[ch].
1457 * Implemented silc silc_client_add_private_message_key,
1458 silc_client_add_private_message_key_ske,
1459 silc_client_del_private_message_key,
1460 silc_client_list_private_message_keys and
1461 silc_client_free_private_message_keys functions in the
1464 Added functions silc_client_send_private_message_key to send
1465 the Private Message Key payload and silc_client_private_message_key
1466 to handle incoming Private Message Key payload.
1468 * Added Cipher field to the Private Message Key payload to set
1469 the cipher to be used. If ignored, the default cipher defined
1470 in the SILC protocol (aes-256-cbc) is used.
1472 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Removed lib/silcclient/ops.h file.
1476 Redefined parts of the SILC Client Library API. Created new
1477 file silcapi.h that deprecates the ops.h file and defines the
1478 published Client Library API. Defined also private message key
1479 API and channel private key API into the file.
1481 This is the file that the application must include from the
1482 SILC Client Library. Other files need not be included by
1483 the application anymore.
1485 * Added new key_agreement client operation callback and also
1486 defined the Key Agreement library API for the application.
1488 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1491 is used by clients to request key negotiation between another
1492 client in the SILC network. If the negotiation is started it
1493 is performed using the SKE protocol. The result of the
1494 negotiation, the secret key material, can be used for example
1495 as private message key.
1497 Implemented the Key Agreement payload into the files
1498 lib/silccore/silauth.[ch].
1500 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Redefined ciphers for the SILC protocol. Added some new ciphers
1503 and defined the key lengths for the algorithms. Changed the
1504 code accordingly. The default key length is now 256 bits.
1506 * Fixed SKE key distribution function silc_ske_process_key_material
1507 when the key length is more than 128 bits. The default key
1508 length in SILC is now 256 bits.
1510 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1511 to indicate unsupported algorithm.
1513 * Renamed rijndael.c to aes.c and all functions as well.
1515 * Fixed a long standing channel key setting bug in client library.
1516 Weird that it has never surfaced before.
1518 * Fixed bug in channel deletion. If the entire channel is removed
1519 then it must also delete the references of the channel entry
1520 from the client's channel list as the client's channel entry and
1521 the channel's client entry share same memory.
1523 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Implemented CONNECT and SHUTDOWN commands in the client.
1527 * Implemented CLOSE command to the client.
1529 * Added the function silc_idlist_find_server_by_name into the
1530 files silcd/idlist.[ch].
1532 Added the function silc_idlist_find_server_by_conn into the
1533 files silcd/idlist.[ch].
1535 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * DIE command was renamed to SHUTDOWN. Updated the both code
1540 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1541 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1543 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1546 * Added function silc_server_create_connection function to create
1547 connection to remote router. My server implementation actually
1548 does not allow router to connect to normal server (it expects
1549 that normal server always initiates the connection to the router)
1550 so the CONNECT command is only good for connecting to another
1553 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1556 or some other client was kicked from the channel.
1558 Implemented the handling of the notify type to both client
1561 Implemented silc_server_send_notify_kicked to send the KICKED
1562 notify. It is used to send it to the server's primary router.
1564 * Implemented the KICK command into server and client.
1566 * Added `query' argument to the silc_idlist_get_client function
1567 to indicate whether to query the client from server or not if
1570 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1571 to indicate that the client is not channel founder.
1575 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1577 * Removed the rng context from SilcPacketContext structure and
1578 changed that the packet routine uses the Global RNG API.
1580 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Added support for quit message that client can "leave" on the
1583 channel when it quits the SILC. It is ditributed inside the
1584 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1586 Added silc_server_free_client_data that will take the
1587 signoff message as argument.
1589 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1591 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Updated parts of the protocol specification to keep it up
1596 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1599 payloads in one packet.
1601 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1602 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1603 use now the new List flag.
1605 * Also deprecated the following packet types: REPLACE_ID,
1606 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1608 * Added list support for Notify packet in server.
1610 * Added silc_server_send_notify_channel_change to send the
1611 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1612 the silc_server_send_replace_id.
1614 * Added silc_server_send_notify_nick_change to send the
1615 NICK_CHANGE notify type. Deprecates the function
1616 silc_server_send_replace_id.
1618 * Added silc_server_send_notify_join to send the JOIN notify type.
1619 Deprecates the function silc_server_send_new_channel_user.
1621 * Added silc_server_send_notify_leave to send LEAVE notify type.
1622 Deprecates the function silc_server_send_remove_channel_user.
1624 * Added silc_server_send_notify_cmode and
1625 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1626 types. Deprecates the silc_server_send_set_mode function.
1628 * Added SERVER_SIGNOFF notify type to indicate that server has
1629 quit. This means that all clients on the channel from that
1630 server will drop. This can be also used when netsplit happens.
1632 Deprecated REMOVE_ID packet type since it is not needed anymore
1635 Added silc_server_send_notify_server_signoff to send the
1636 SERVER_SIGNOFF notify type. Deprecates the function
1637 silc_server_send_remove_id.
1639 Added also silc_server_send_notify_signoff to send the
1640 SIGNOFF notify type.
1642 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1643 SILC protocol from this day on. Changed the protocol
1644 specification as well.
1646 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1647 notify type. It is used between routers to notify about
1648 topic changes on a channel.
1650 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1653 * Partly updated the protocol specification to comply with the
1654 changes now made. It is still though a bit outdated.
1656 * The JOIN notify type now takes one extra argument <Channel ID>.
1657 The packet used to be destined to the channel but now the
1658 JOIN type may be sent as list thus it is impossible to
1659 destine it to any specific channel. By adding this argument
1660 it is again possible.
1662 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Added CREDITS file. The CHANGES and CREDITS file will appear
1665 in the distribution as well.
1667 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1670 types in the server's silcd/packet_receive.c.
1672 * Implemented CMODE and CUMODE to work in router environment.
1674 * Fixed minor encoding and decoding buglet from the
1675 lib/silccore/silcmode.c.
1677 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1680 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1682 * Changed all SilcConfigServer* and silc_config_server* to
1683 SilcServerConfig* and silc_server_config*, respectively.
1686 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Associated the ID (client or server ID) to the Authentication
1689 Payload to avoid any possibility of forging. Updated the
1690 protocol specification and the code accordingly.
1692 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * The RSA key length is now save to the RsaKey context in the
1695 key generation process in lib/silccrypt/rsa.c. The key length
1696 is now used to figure out the maximum size of the block allowed
1697 to be encrypted/signed.
1699 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1700 is equivalent to the silc_mp_mp2bin but does not allocate any
1703 * Changed silc_mp_mp2bin API to take length argument. If it is
1704 non-zero then the buffer is allocated that large. If zero, then
1705 the size is approximated using silc_mp_sizeinbase, which however
1708 * Created Global RNG API which is global RNG that application can
1709 initialize. After initializing, any routine anywhere in the
1710 code (including library) can use RNG without allocating a new
1711 RNG object. This was done to allow this sort of use of the
1712 RNG in code that has no chance to allocate RNG object. All
1713 applications currently allocate this and many routines in the
1714 library use this. Affected file lib/silccrypt/silcrng.[ch].
1716 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1717 it to use the Global RNG API.
1719 * Defined Authentication Payload into protocol specification that
1720 is used during SILC session to authenticate entities. It is
1721 used for example by client to authenticate itself to the server
1722 to obtain server operator privileges.
1724 Implemented this payload into the lib/silccore/silcauth.[ch].
1725 Implemented also routines for public key based authentication
1726 as the new protocol specification dictates.
1728 Moved definitions of different authentication methods from
1729 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1731 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1732 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1733 silc_pkcs_verify_with_hash functions into the file
1734 lib/silccrypt/silcpkcs.[ch].
1736 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * The client entry's userinfo pointer must be always valid.
1739 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1740 will fail since it requires the userinfo. Now, the userinfo
1741 is allocated as "" if actual userinfo does not exist. Actually,
1742 it must exist and it is totally Ok to drop client connections
1743 that does not announce the userinfo. However, we will make
1744 this workaround for now.
1746 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1747 to return the remote port by socket.
1749 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1752 SILC_SERVER_PENDING_EXEC and added an new macro
1753 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1754 data or when error occurs while processing the pending command.
1756 Added new argument `destructor' into silc_server_command_pending
1757 and to the SilcServerCommandPending object. This destructor is
1758 now called after calling the pending callback or if error occurs
1759 immediately. If error occurs the actual pending callback won't
1760 be called at all - only the destructor. The destructor may be
1761 NULL if destructor is not needed.
1763 All this applies for client library code as well. Similar
1764 changes were made there as well for the pending commands.
1766 In the client, the application must now allocate the
1767 SilcClientCommandContext with the silc_client_command_alloc
1770 * Added reference counter to the SilcServerCommandContext. Added
1771 function silc_server_command_alloc and silc_server_command_dup
1774 Same type of functions added to the client library for the same
1777 * Removed the cmd_ident from IDListData away since it is now
1778 global for all connections. It is the command identifier used
1779 in command sending and with pending commands. The affected file
1782 * Added reference counter to the SilcSocketConnection objecet to
1783 indicate the usage count of the object. The object won't be
1784 freed untill the reference counter hits zero. Currently only
1785 server uses this, and client ignores it. The client must be
1786 set to use this too later. The affected files are
1787 lib/silccore/silcsockconn.[ch]. Added also the function
1788 silc_socket_dup to increase the reference counter.
1790 This was mainly added because it is possible that the socket
1791 is removed underneath of pending command or other async
1792 operation. Now it won't be free'd and proper DISCONNECTING
1793 flags, etc. can be set to avoid sending data to connection that
1794 is not valid anymore.
1796 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1797 the connection. After that it sets SILC_SET_DISCONNECTED.
1798 It is, however, possible that the socket data is not still freed.
1799 The silc_server_packet_process now checks that data is not
1800 read or written to connection that is DISCONNECTED. The socket
1801 get's freed when the reference counter hits zero.
1803 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Changed the client operation API: channel_message operation's
1806 `sender' is now the client entry of the sender, not the nickname
1807 and the `channel' is the channel entry, not the channel name.
1809 In the private_message operation the `sender' is now also the
1810 client entry of the sender not the nickname.
1812 Affected file is lib/silcclient/ops.h and all applications
1813 using the client operations.
1815 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Moved the calling of ops->connect() from connect_to_server_final
1818 into receive_new_id functin since that is the point when the
1819 client is actually allowed to send traffic to network. The
1820 affected file is lib/silcclient/client.c.
1822 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1825 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1826 (if needs broadcasting) instead of broadcasting the packets one
1827 by one which would make a burst in the network traffic.
1829 * Added `broadcast' argument to the functions in silcd/server.[ch]
1830 silc_server_create_new_channel[_with_id] to indicate whether
1831 to send New Channel packet to primary router.
1833 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Added new function into the silcd/server.[ch] files:
1836 silc_server_create_new_channel_with_id to create new channel with
1837 already existing Channel ID.
1839 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1840 lib/silccore/silcpacket.h. This packet is used t send list of
1841 Set Mode payloads inside one packet. Server uses this to set
1842 the modes for the channels and clients on those channels, that it
1843 announced to the router when it connected to it. The protocol
1844 specification has been updated accordingly.
1846 * The silc_server_new_channel did not handle the packet coming
1847 from normal server as it normally does not send that. However,
1848 when it announces its channels it does send it. Implemented
1849 the support for that.
1851 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1852 into the file lib/silccore/id.h.
1854 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Fixed memory leaks in the functions silc_idlist_del_client,
1857 silc_idlist_del_channel and silc_idlist_del_server in the file
1858 silcd/idlist.c. All of those leaked like a sieve.
1860 * Fixed some small memory leaks in the client's function
1861 silc_client_notify_by_server.
1863 * Added functions into silcd/server.c: silc_server_announce_clients,
1864 silc_server_announce_channels and silc_server_announce_server.
1865 These functions are used by normal and router server to announce
1866 to its primary router about clients, channels and servers (when
1867 router) that we own. This is done after we've connected to the
1870 These functions effectively implements the following packet types:
1871 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1872 and SILC_PACKET_NEW_ID_LIST.
1874 * Added new functions into the silcd/packet_receive.[ch]:
1875 silc_server_new_id_list, silc_server_new_channel_list and
1876 silc_server_new_channel_user_list to handle the incoming
1877 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1879 * Added support of changing Channel ID in the function
1880 silc_server_replace_id. If the server that announces a channel
1881 to the router already exists in the router (with same name but
1882 with different Channel ID), router is responsible to send
1883 Replace ID packet to the server and force the server to change
1884 the Channel ID to the one router has.
1886 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1887 client that the Channel ID has been changed by the router. The
1888 normal server sends this to the client. Client must start using
1889 the new Channel ID as the channel's ID.
1891 Implemented handling of this new type into lib/silcclient/client.c
1892 into the function silc_client_notify_by_server.
1894 * Added new function silc_idlist_replace_channel_id into the files
1895 silcd/idlist.[ch] to replace the Channel ID.
1897 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Call silc_server_command_identify_check always when processing
1900 the IDENTIFY command in silcd/command.c
1902 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1905 send keepalive packets. The packet can be sent by clients,
1906 servers and routers.
1908 Added function silc_socket_set_heartbeat into the file
1909 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1910 If not set, the heartbeat is not performed. The actual
1911 heartbeat is implemented in the low level socket connection
1912 library. However, application is responsible of actually
1915 Added silc_server_send_heartbeat to send the actual heartbeat
1916 packet into silcd/packet_send.[ch]. Server now performs
1917 keepalive with all connections.
1919 * Added silc_task_get_first function into lib/silcutil/silctask.c
1920 to return the timeout task with shortest timeout. There was a bug
1921 in task unregistration that caused problems. TODO has been
1922 updated to include that task system must be rewritten.
1924 * The client library will now resolve the client information when
1925 receiving JOIN notify from server for client that we know but
1926 have incomplete information.
1928 * Rewrote parts of silc_server_remove_from_channels and
1929 silc_server_remove_from_one_channel as they did not remove the
1930 channel in some circumstances even though they should've.
1932 * Encryption problem encountered in server:
1934 The LEAVE command used to send the Channel Key packet to the
1935 router immediately after generating it. However, the code
1936 had earlier sent Remove Channel user packet but not immediately,
1937 ie. it was put to queue. The order of packets in the router
1938 was that Channel Key packet was first and Remove Channel User
1939 packet was second, even though they were encrypted in the
1940 reverse order. For this reason, MAC check failed. Now, this
1941 is fixed by not sending the Channel Key packet immediately but
1942 putting it to queue. However, this is more fundamental problem:
1943 packets that are in queue should actually not be encrypted
1944 because packets that are sent immediately gets encrypted
1945 actually with wrong IV (and thus MAC check fails). So, packets
1946 that are in queue should be encrypted when they are sent to
1947 the wire and not when they put to the queue.
1949 However, the problem is that the current system has not been
1950 designed to work that way. Instead, the packet is encrypted
1951 as soon as possible and left to the queue. The queue is then
1952 just purged into wire. There won't be any fixes for this
1953 any time soon. So, the current semantic for packet sending
1956 o If you send packet to remote host and do not force the send
1957 (the packet will be in queue) then all subsequent packets to the
1958 same remote host must also be put to the queue. Only after the
1959 queue has been purged is it safe again to force the packet
1962 o If you send all packets immediately then it safe to send
1963 any of subsequent packets through the queue, however, after
1964 the first packet is put to queue then any subsequent packets
1965 must also be put to the queue.
1967 Follow these rules and everything works fine.
1969 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Added new function silc_server_remove_clients_by_server to
1972 remove all client entries from ID list when the server connection
1973 is lost. In this case it is also important to invalidate all
1974 client entires as they hold the invalid server entry. This
1975 fixes fatal bug when server has lost connection and will reconnect
1978 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Made some sanity checks to silc_server_daemonise like to check
1981 whether the requested user and group actually exists.
1983 * Added sanity check to SKE's silc_ske_responder_finish to check
1984 that the public and private key actually is valid.
1986 * Invalidate the client's nickname when receiving Replace ID
1987 packet and the Client ID is being replaced. This means that the
1988 server will query the nickname if someone needs it (client)
1991 * Sort the ID Cache in client library when the ID Cache data
1992 has changed (needs sorting).
1994 * Do not allow for SILC client to create several connections to
1995 several servers. The client does not support windows right now
1996 and generating multiple connections causes weird behaviour.
1998 Irssi-silc client does support windows and can handle several
1999 connections without problems, see: www.irssi.org and SILC plugin.
2001 * Fixed some places where client was added to the IDList. The
2002 rule of thumb is following (in order to get everything right):
2003 If the client is directly connected local client then the
2004 `connection' argument must be set and `router' argument must be
2005 NULL to silc_idlist_add_client function. If the client is not
2006 directly connected client then the `router' argument must
2007 bet set and the `connection' argument must be NULL to the
2008 silc_idlist_add_client function.
2010 * The funtion silc_server_packet_send_local_channel actually did
2011 not check whether the client was locally connected or not. It
2012 does that now. Fixed a bug related to LEAVE command.
2014 * Fixed Remove Channel User payload parsing bug in server's
2015 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2017 * The server's silc_server_save_channel_key now checks also the
2018 global ID list for the channel as it might not be in the local
2019 list. Fixed a bug related to LEAVE command.
2021 * Is this the end of the [<unknown>] buglet that has been lurking
2022 around for a long time? A little for loop fix in server's
2023 silc_server_command_whois_parse that is used by both IDENTIFY
2024 and WHOIS command. At least, this was a clear bug and a cause
2025 of one type of [<unknown>] buglet.
2027 * WHOIS and IDENTIFY commands call the function
2028 silc_server_command_[whois/identify]_check function even if
2029 we are not router server.
2031 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * Added --with-gmp configuration option. If set the GMP
2034 is always compiled in the SILC source tree. If not set then
2035 it is checked whether the system has the GMP3 installed. If
2036 it has then the GMP won't be compiled (the system's headers
2037 and library is used), if it doesn't have it then the GMP is
2038 compiled in the SILC source tree.
2040 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2042 * Changed RSA private exponent generation to what PKCS #1
2043 suggests. We try to find the smallest possible d by doing
2044 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2045 not security fix but optimization.
2047 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Added new config entry [Identity] to fork the server and run
2050 it as specific user and group. A patch from Bostik.
2052 * Imported Dotconf configuration library into lib/dotconf.
2053 This will be used to create the SILC configuration files later.
2054 It will appear in the distsribution after this commit.
2056 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * A big code auditing weekend happening. Auditing code for
2059 obvious mistakes, bugs and errors. Also, removing any code
2062 Removed files for being obsolete:
2064 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2065 inline in the file lib/silcutil/silcbuffer.h)
2067 o lib/silcutil/silcbufutil.c (the header has inline versions)
2069 Changed code to fix possible error conditions:
2071 o The buffer formatting routines now check that the destination
2072 buffer really has enough space to add the data. This applies for
2073 both buffer formatting and unformatting
2074 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2075 unformatting was changed to accomodate following rules:
2076 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2077 sent to the function while XXX_*STRING will not allocate or copy
2078 the data into the buffer. Instead it sets the pointer from the
2079 buffer into the pointer sent as argument (XXX_*STRING used to
2080 require that the pointer must be allocated already). This change
2081 makes this whole thing a bit more consistent and more optimized
2082 (note that the data returned in the unformatting with XXX_*STRING
2083 must not be freed now). The routines return now -1 on error.
2085 o Tried to find all code that use buffer_format and buffer_unformat
2086 and added return value checking to prevent formatting and
2087 especially unformatting errors and possible subsequent fatal
2090 o Changed ske->x and ske->KEY to mallocated pointers in
2091 lib/silcske/silcske.h. Fixed possible data and memory leak.
2093 o Added return value checking to all *_parse* functions. Fixed
2094 many memory leaks as well.
2096 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2097 so that buffer overflows would not happen. All code now also
2098 checks the return value as it can fail.
2100 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Added reconnection support to server if the normal server looses
2103 its connection to the router (for example if router is rebooted).
2104 The server performs normal reconnection strategy implemented
2105 to the server. Affected file silcd/server.c.
2107 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Added new packet type SILC_PACKET_SET_MODE that is used to
2110 distribute the information about changed modes (for clients,
2111 channels and clients channel modes) to all routers in the
2112 network. Updated the protocol specification accordingly.
2114 Added functions into silcd/packet_send.c and
2115 silcd/packet_receive.c: silc_server_send_set_mode,
2116 silc_server_set_mode.
2118 Added new files silcmode.[ch] into lib/silccore that implements
2119 the encoding and decoding of Set Mode Payload. Added new type
2120 SilcSetModePayload. Moved the definitions of different modes
2121 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2123 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Oops, a little mistake in server's connection authentication
2126 protocol. The protocol is not ended with FAILURE but with
2127 SUCCESS if the authentication is Ok. :) Affected file is
2130 * Implemented NICK_CHANGE notify handling in server in the file
2131 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2132 the local clients on the channel. After the changing nickname
2133 in router environment snhould work and the [<unknown>] nickname
2134 should appear no more.
2136 The silc_server_replace_id function that receives the Replace ID
2137 payload now sends the NICK_CHANGE notify type also in the file
2138 silcd/packet_receive.c
2140 * Changed WHOIS and IDENTIFY command to support the maximum amount
2141 of arguments defined in protocol specs (3328 arguments). This
2142 fixed a bug that caused problems when there were more than three
2145 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Added extra parameter, command identifier, to the
2148 silc_client_send_command so that explicit command identifier
2151 Changed that ID list routines uses specific command identifier
2152 when sending WHOIS/IDENTIFY requests to the server so that they
2153 can be identified when the reply comes back.
2155 Affected files lib/silcclient/command.[ch],
2156 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2158 * Added `sender' argument to silc_server_packet_send_to_channel
2159 to indicaet the sender who originally sent the packet to us
2160 that we are now re-sending. Ignored if NULL. Affected file
2161 silcd/packet_send.[ch].
2163 * Added some server statistics support in silcd/server_internal.h
2164 SilcServerStatistics structure and around the server code. Also
2165 send some nice statistics information when client is connecting
2168 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Fixed channel ID decoding in server's JOIN command reply in
2171 silcd/command_reply.c
2173 * Fixed braodcasting of replace ID payload to not to send it if
2174 we are standalone server in silcd/packet_receive.c.
2176 * Fixed all channel message sending routines to not to send
2177 packets to clients that has router set, since they are routed
2178 separately in the same function earlier. Affects file
2179 silcd/packet_send.c and all channel packet sending functions.
2181 * In USERS reply, res_argv[i] are not allocated, the table
2182 is allocated. Thus changed that free the table, not its
2185 * In server's whois_check and identify_check if the client is
2186 locally connected do not send any WHOIS commands - they are not
2189 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Fixed some minor bugs in client when sending WHOIS command. The
2192 arguments was in wrong order.
2194 * Removed statis function add_to_channel from server in
2195 silcd/command.c that was previously used with the joining but
2198 * Tested USERS command in router environment successfully with two
2199 routers, two servers and two clients.
2201 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Reorganized the USERS command and command reply in client library
2204 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2205 When the command is given by user we register a pending command
2206 callback that will reprocess the command after the reply has been
2207 received from the server. When reprocessing the packet we then
2208 display the information. Thus, the USERS information is displayed
2209 now in the command callback instead of in the command reply
2210 callback. The processing of the command is same as previously
2211 when server has sent the command reply in the JOINing process.
2213 * Added to USERS command in silcd/command_reply.c to join the client,
2214 we didn't use to know about, to the channel after we've created
2215 a client entry for it. Also, for clienet we did know already still
2216 check whether it is on the channel or not and add it if not.
2218 * Removed silc_server_command_join_notify as the function and its
2221 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Changed the client's pending command handling to the same as the
2224 server's pending command handling. It is also now possible to
2225 execute command reply functions from other command reply
2226 function as the function callbacks for commands and command
2227 replies are one and same. The pending commands are not static
2228 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2229 in client connection context. Thus, pending commands are server
2230 connection specific as it is convenient.
2232 Changed the function silc_client_command_pending and
2233 silc_client_command_pending_del and added new function
2234 silc_client_command_pending_check. Removed the
2235 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2238 * Added cmd_ident, current command identifier, to the client
2239 connection context in lib/silcclient/client.h to keep track on
2240 command identifiers used in command sending. Client's command reply
2241 function handling now supports the mandatory command identifiers.
2243 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2244 funtions in client to fully support pending command callbacks.
2246 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2247 as one of the arguments to the application in the command reply
2250 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2251 before first releasing SILC but came back. Now it is removed again
2252 and should come back nomore. The FORWARDED flag was used only
2253 by the JOINing procedure by forwarding the command packet to router.
2254 Now, the JOINing procedure has been changed to more generic (due
2255 to various router environment issues) and FORWARDED is not needed
2256 anymore for anything. The protocol specification is yet to be
2259 Now, removed silc_server_packet_forward from server and the flag
2260 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2262 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Renamed NAMES command to USERS command. The NAMES was named that
2265 due to historical reasons. Now it is renamed. Also, rewrote
2266 parts of the USERS command. The nickname list is not sent anymore
2267 by the server. Only Client ID and mode lists are sent in the USERS
2268 command. Changed this also to the protocol specification.
2270 The client now resolves the names and stuff after it receives
2271 the USERS list from the server when joining to the channel.
2273 * WHOIS and IDENTIFY commands has been changed to support multiple
2274 Client ID's per command. One can now search for multiple users
2275 in the network by sending only one WHOIS or IDENTIFY command.
2276 Changed the code and the protocol specifications.
2278 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2279 uses silc_server_command_whois_parse to parse the request. */
2281 * If normal server, do not parse the WHOIS and IDENTIFY requests
2282 before sending it to the router. Saves some time.
2284 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Fixed JOIN command on client library. Wrong number of arguments
2287 used to crash the client.
2289 * Added silc_server_channel_has_global function to check whether
2290 channel has global users or not.
2292 * Added silc_server_channel_has_local function to check whether channel
2293 has locally connected clients on the channel.
2295 * The silc_server_remove_from_one_channel now checks whether the
2296 channel has global users or not after given client was removed from
2297 the channel. It also checks whether the channel has local clients
2298 on the channel anymore. If it does not have then the channel entry
2299 is removed as it is not needed anymore.
2301 * The silc_server_notify now checks on JOIN notify whether the joining
2302 client is one of locally connected or global. If it is global then
2303 the channel has now global users on the channel and that is marked
2304 to the channel entry. Also, it now saves the global client to
2305 global list who is joining and JOINs it to the channel. This is
2306 for normal server, that is.
2308 Changed silc_server_send_notify_on_channel,
2309 silc_server_packet_relay_to_channel and
2310 silc_server_packet_send_to_channel check if we are normal server
2311 and client has router set (ie. global client) do not send the
2312 message to that client, as it is already routed to our router.
2314 * Implemented LEAVE notify type handling in silc_server_notify
2317 * Tested LEAVE command in router environment successfully. Tested
2318 with two routers, two servers and two clients.
2322 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2324 * Implemented SIGNOFF notify type handling in silc_server_notify
2327 * silc_server_remove_id now removes the client entry from all channels
2328 it has joined and thusly sends SIGNOFF notify type.
2330 * Rewrote the NAMES list generation in server by removing two excess
2331 loops. The lists are created now inside one loop.
2333 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * silc_server_remove_channel_user checks now also global list
2336 for channel and client.
2338 * silc_server_new_channel_user checks now both local and global
2339 list for channel and client. Fixed a bug in client id decoding.
2340 Used to decode wrong buffer.
2342 * silc_server_channel_message checks now both local and global
2343 list for channel entry.
2345 * Tested channel joining (hence JOIN) in router environment
2346 successfully. Tested with two routers, two servers and two
2349 * Tested channel message sending in router environment successfully.
2351 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Added silc_server_save_channel_key into server.[ch] to save the
2354 received channel key in Channel Key payload processing. It is
2355 also used in JOIN command reply handling.
2357 Equivalent function silc_client_save_channel_key added into
2358 client.[ch] into client library.
2360 * Changed JOIN command reply to send information whether the channel
2361 was created or not (is existing already) and the channel key
2362 payload. Changed protocol specs accordingly.
2364 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2365 the request was sent by ID and not by nickname. Crashed on
2368 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2371 now correctly save the received data.
2373 * silc_server_free_sock_user_data now notifies routers in the
2374 network about entities leaving the network.
2376 At the same time implemented functions silc_server_remove_id
2377 and silc_server_send_remove_id to receive and send REMOVE_ID
2378 packets. The packet is used to notify routers in the network
2379 about leaving entities. The ID removed will become invalid in
2382 * Added function silc_idlist_del_server into server. Removes and
2383 free's server entry from ID list.
2385 * silc_server_private_message function now checks, if we are router,
2386 that the destination ID really is valid ID, naturally.
2388 * In router when NEW_ID packet is received (for new client) the
2389 hash of the Client ID is saved in the ID Cache but the
2390 client->nickname is set to NULL, instead of putting the hash
2393 IDENTIFY command now also checks that client->nickname must be
2394 valid. If it is not if will request the data from the server who
2395 owns the client. Added new function
2396 silc_server_command_identify_check.
2398 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2399 to set the command to already allocated Command Payload.
2401 * Tested private message sending in router environment with two
2402 routers, two servers and two clients. Fixed minor bugs and now
2405 * Fixed segfault from client's NAMES command. Used to crash if
2408 * Forwarded packets must not be routed even if it is not destined
2409 to the receiver. Changed server code comply with this.
2411 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Added `require_reverse_mapping' boolean value to ServerParams
2414 structure. If TRUE (not default) the server will require that
2415 the connecting host has fully qualified domain name.
2417 If the reverse mapping is not required and hostname could not be
2418 found the IP address is used as hostname.
2420 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Implemented version string checking to both client and server.
2423 The check is incomplete currently due to the abnormal version
2424 strings used in development version of SILC.
2426 * Changed all command functions in server to use the new
2429 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Changed char *data to unsigned char *data in ID Cache system to
2432 support binary data as ID Cache data. Changed code to support
2433 binary data in lib/silccore/idcache.c.
2435 * Renamed silc_server_packet_relay_command_reply to
2436 silc_server_command_reply as it is normal packet receiving
2437 function. Rewrote the function to accept command replys for
2438 servers and not only for clients.
2440 * Mark remote router always as registered server if we are connecting
2441 to it. Otherwise, commands sent by the router to us are ignored.
2443 * All ID List find routines now returns the ID Cache Entry pointer
2444 as well if requested.
2446 * WHOIS command works now in router environment, tested with two
2447 routers, two servers and two clients.
2449 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2450 in router environment (as it is almost equivalent to WHOIS) but
2451 hasn't been tested thoroughly. Added new functions:
2453 silc_server_command_identify_parse
2454 silc_server_command_identify_send_reply
2455 silc_server_command_identify_from_client
2456 silc_server_command_identify_from_server
2458 * Disabled route cache adding because adding two different ID's with
2459 same IP replaces the old cache entry thus giving wrong route.
2460 The entry->router->connection is always the fastest route anyway
2461 so route cache may not be needed. Of course, new routes maybe
2462 established after receiving the ID when the entry->router->connection
2463 might not be anymore the most optimal.
2465 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Add route cache for received ID for fast routing.
2469 * Added silc_server_packet_route to route received packet on router
2470 that is not destined to us.
2472 * Renamed silc_server_get_route to silc_server_route_get.
2474 * Added id_string and id_string_len fields into SilcServer to
2475 include encoded ServerID for fast comparing without excess
2476 encoding of the ID's.
2478 * Cleaned up WHOIS command on server side. Added following static
2481 silc_server_command_whois_parse
2482 silc_server_command_whois_check
2483 silc_server_command_whois_send_reply
2484 silc_server_command_whois_from_client
2485 silc_server_command_whois_from_server
2487 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2488 arguments in command replies. All command functions should be
2489 updated to use this macro.
2491 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Minor typo fixes on command reply handling on server.
2495 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Added silc_server_command_add_to_channel internal routine to add
2498 the client to the channel after router has created the channel and
2499 sent command reply to the server.
2501 * Added generic silc_server_send_command to send any command from
2504 * Use static buffer with ID rendering instead of duplicating data.
2506 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Fixed a channel user mode bug when joining to a channel server gave
2509 everybody channel founder rights, oops.
2511 * We mark ourselves as the router of the incoming server connection
2512 if we are router ourselves. This way we can check in some packet
2513 sending functions whether it is locally connected server. For
2514 incoming router connections we put NULL.
2516 * For router sending packets locally means now always sending the
2517 packet cell wide; to local clients and local servers. For normal
2518 server sending packet locally means sending it to only local
2521 * Fixed the JOIN command to really work in router environment. If the
2522 channel is created it is always created by the router. Router is
2523 also responsible of making the initial joining to the channel,
2524 sending JOIN notify to the sending server and distributing
2525 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2526 does not exist server doesn't do anything else but forward the
2527 command to the router which performs everything.
2529 * Added silc_server_send_channel_key function to send the Channel Key
2532 * Added silc_server_create_channel_key to create new channel key. The
2533 channel key is now re-generated everytime someone joins or leaves
2534 a channel, as protocol dictates. Note: channel->key_len is the
2537 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2540 packet_receive.[ch] to separate packet sending and receiving
2541 routines. The server.[ch] now includes everything else including
2542 actual packet processing (writing and reading data) and other
2545 Renamed silc_server_private_message_send_internal to
2546 silc_server_send_private_message. The routine is still though
2547 used only to relay private messages as server does not send
2548 private messages itself.
2550 Renamed silc_server_new_channel to silc_server_create_new_channel
2551 and added new function sicl_server_new_channel that handles the
2552 incoming New Channel packet. Added also new sending function
2553 silc_server_send_new_channel to send New Channel Payload.
2555 * Added new function silc_server_notify to process incoming notify
2556 packet to the server/router. Server may then relay the notify
2557 to clients if needed.
2559 * Added new function silc_server_new_channel_user to process incoming
2560 New Channel User packet. Router will redistribute the packet and
2561 send JOIN notify to its local clients and locally connected servers
2562 if needed. Normal server will send JOIN notify to its local client
2563 on same channel when received this packet. Added also corresponding
2564 sending function silc_server_send_new_channel_user to sent the
2567 * Added boolean route argument to send_notif_to_channel and
2568 packet_send_to_channel functions to attempt to route the packet
2569 if it is TRUE and send only locally if it is FALSE.
2571 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * silc_server_replace_id now broadcasts the received replace ID
2574 packet if it is not broadcast packet already. The router must
2575 broadcast to inform other routers about changed ID.
2577 * Added backpointer to server's router into SilcServer context in
2578 silcd/server_internal.h.
2580 * Fixed silc_server_packet_broadcast to send correct broadcast
2583 * The channel key is now distributed to the local client as soon
2584 as it is received from the router (in router environment) so that
2585 no other packet may be sent for the channel until client has
2588 * silc_server_remove_channel_user now broadcasts the received
2589 Remove Channel User packet if it is not broadcast packet already.
2590 The router must broadcast to inform other routers about removed
2593 * Added users field into SilcPacketContext that is a reference count
2594 of the context. One can increase the reference count by calling
2595 silc_packet_context_dup which is now changed to just increase the
2596 reference count instead of duplicating the data. The reference
2597 count is decresed by calling silc_packet_context_free that will
2598 free the data after the reference count hits zero.
2600 For now on the packet context and everything allocated into it
2601 (including the raw packet from network) must be freed by calling
2602 the new silc_packet_context_free function. Added also new function
2603 silc_packet_context_alloc that must be used now to allocate the
2604 context. This also means that if a routine is asynchronous from
2605 silc_[client/server]_packet_parse_type the packet context must
2606 be duplicated by calling silc_packet_context_dup. Otherwise it
2607 gets free'd after silc_[client/server]_packet_parse_type returns.
2608 Also, one must remember that if packet is duplicated then its
2609 reference count must be decresed by calling the free function as
2610 many times as it was duplicated.
2612 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2613 from both client and server.
2615 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Made joining to a channel working in router environment.
2619 * Cleaned up JOIN command on server side and create function
2620 silc_server_command_join_channel internal routine to make the
2623 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Changed silc_command_pending list to SilcDList. Also, added
2626 `ident' field to SilcServerCommandPending structure to identify
2627 the reply and to call correct callback.
2629 Added silc_server_command_pending_check function to replace the
2630 corresnponding macro. The silc_command_pending list is not
2633 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2634 to set identifier to previously allocated Command Payload. It
2635 is used to set identifier for command when resending Command
2638 * Added silc_command_payload_encode_payload to encode Command
2639 Payload buffer from SilcCommandPayload structure.
2641 * Added silc_argument_payload_encode_payload to encode Argument
2642 payload buffer from SilcArgumentPayload structure.
2644 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Changed WHOIS command to support router connection on server side.
2647 The whois request is always sent to router unless the server is
2648 standalone server. After server has received the reply from the
2649 router will it send the reply to the client.
2651 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2652 broadcast received broadcast packet. The function is used only
2653 by router. The broadcast packet is always sent to the router's
2656 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2657 render given ID to printable string, for log files for example.
2659 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Made basic router to router connections working. At least they
2662 can now connect to each other but nothing really works the way
2663 they are supposed - yet.
2665 * Added new initiator token to RouterConnection configuration
2666 file in silcd/serverconfig.[ch]. It is used to tell whether we
2667 are the initiator to the remote router or whether we'll expect
2668 the other end to connect.
2670 * Moved registering of listener task to silc_server_init, hence
2671 the server starts listenning as soon as it is run, even if it
2672 does not have connections to other routers. Let's see how well
2675 * Changed default connection retry timeouts for more suitable in
2678 * Removed cipher and such arguments from silc_idlist_add_client
2679 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2680 Added new function silc_idlist_add_data to add the keys and stuff
2683 * Added SilcIDListData structure and added it to SilcClientEntry
2684 and SilcServerEntry as their first field in the structure. This
2685 way we can explicitly cast the ID entries to the SilcIDListData
2686 structure and get common data for the entries. In past, we had
2687 to first check what type of connection it is and then cast it to
2688 correct ID entry type. Now, we can directly cast the opaque
2689 pointer to the SilcIDListData (no matter what ID entry it actually
2690 is) and get the data needed.
2692 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2695 in some circumstances even if threre were timeout tasks, though not
2696 IO tasks, but tasks anyway. Now fixed.
2698 * Defined SilcServerConnection structure to hold connection specific
2699 stuff about directly connected servers and routers. The definition
2700 is currently in silcd/server_internal.h. I thought about having
2701 a bit more important role fro this struct but for now it is used
2702 only when connecting to other server (or router actually).
2704 * Added connecting retry support in server when connecting to
2705 router(s). The retry feature implement exponential backoff
2706 algorithm. Also, added SilcServerParams structure to hold default
2707 parameters for server. For now, it include these retry settings
2708 and are hard coded. After server is moded to be as Silc Server
2709 Library this structure will be more important.
2711 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2713 * Changed client librarys channel->clients table to SilcList and
2714 changed code accordingly.
2716 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2718 * Changed client's channel table to SilcList and changed code
2719 accordingly. Also changed SilcChannelClientEntry to include back-
2720 pointer to the channel so that client entry can use that structure
2721 as list as well and we have fast cross-reference to the channel.
2722 This change dramatically decreased the complexity of channel
2723 handling with client entry and vice versa (removed one extra
2724 loop when searching for channel entry from many functions).
2726 * Changed server->sim from table to SilcDList and changed code
2729 * NAMES command can now be used from user interface. It will show
2730 the user list on the channel, neatly.
2732 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2733 Code now saves realname of the user if it becomes available.
2735 * Renamed configure.in to configure.in.pre and made ./prepare
2736 script to automatically add correct version string to
2737 configure.in which it creates from configure.in.pre.
2739 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * NAMES command reply now shows users mode with the nickname when
2744 * Moved silc_client_ch[u]mode[_char] functions from
2745 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2746 place sucks, they are utility functions and should be in some
2749 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2751 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2754 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Added TRQ (efficient deque and list library) into lib/trq. This is
2759 a very good list library that is currently used in the SILC. Defined
2760 SilcList API over the library because I didn't like the API very
2761 much. See lib/trq/silclist.h for the API and examples of how to
2762 use the API. Fixed various places in the code to use the new
2763 SilcList API. The SilcList is meant for lists that has a structure
2764 already defined as a list. It is not suitable to add just some
2765 context to the list (in TRQ, the context is the list actually).
2767 So, I defined SilcDList that can be used for the purpose where
2768 predefined list structure does not exit. This can be used as
2769 such list. Now some context just can be added to the SilcDList.
2770 Currently this list is not used in the SILC just yet, though there
2771 are a lot places where this can replace dynamically allocated
2772 tables and I will fix these places, later, to use SilcDList.
2773 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2774 and use TRQ internally).
2776 Also fixed some annoying warning messages that the original TRQ
2777 code generated. Also minor changes to TRQ's Makefile.in.
2779 * Added support for querying by Client ID to both WHOIS and
2780 IDENTIFY commands into server, as required by the protocol.
2782 * Removed method function pointers from SilcBuffer structure. They
2783 weren't used to anything and just increased the context size for
2784 no good reason. This change also made silc_buffer_alloc and
2785 silc_buffer_free functions inline functions.
2787 * Disabled command flooding detection support until it's fixed so
2788 that it accepts commands in but does not execute them more than once
2791 * Added silc_net_localhost(), to return local hostname, into
2792 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2793 that must be initialized before calling silc_client_init.
2795 * Added new function: silc_server_send_notify_on_channels to send
2796 notify messages to all channels client has joined. It is assured
2797 that the message is sent only once per client.
2799 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2800 lib/silcutil/silcutil.[ch] as silc_format function. The new
2801 function is generic and is used by server as well, not only by
2802 the logging routines.
2804 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2805 the provided version string was not acceptable. Added new function:
2806 silc_ske_check_version into lib/silcske/silcske.h. The function
2807 must be implemented by the application (client or server) and it
2808 does not reside in the SKE library. The function checks the version
2809 string remote end sent.
2811 * Added back pointers (to opaque context and to SilcSocketConnection)
2812 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2814 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2815 duplicate packet context structure.
2817 * Changed `notify' client operation to send same arguments as client
2818 receives from server except for ID's. ID's are mapped to correct
2819 ID entry and that is returned. Also, if channel entry is not sent
2820 by server but the notify is for channel the channel entry is sent
2821 to application (otherwise application doesn't know that it is for
2822 channel (library gets it from packet's Destination ID)).
2824 * Added silc_client_remove_from_channels into client library to
2825 remove a client from all channels it has joined to. Used when
2826 received SIGNOFF notify from server. Added also new function
2827 silc_client_replace_from_channels to replace old ID entry with
2828 new ID entry on all channels. Used when received NICK_CHANGE
2831 * Fixed ID Cache list handling in silc_idlist_get_client in
2832 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2833 to get (or query) client by ID.
2835 * Updated TODO list.
2837 * Added connection authentication status message defined by the
2838 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2839 support for these into the code in client and server side.
2841 * Added generic function silc_client_send_command to send any command
2842 with variable argument list. Application should use this function
2843 to send commands if the command functions provided by the library
2844 does not suite for the application's user interface needs.
2846 * Added new `failure' client operation. Application is notified about
2847 received failure packet if client is executing a protocol. In this
2848 case the protocol's execution has failed.
2850 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2851 is required by the protocol.
2853 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2854 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2857 * Added status flag to SilcSKE object to indicate realtime status
2858 of the SKE protocol.
2860 * Application receives now exactly same command reply arguments as
2861 the library receives from server. However, if ID is received the
2862 corresponding ID entry is returned to the application (eg. Client
2863 ID is mapped to correct SilcClientEntry entry and that is returned).
2864 Changed command_reply client operation due to this change.
2866 * Changed all ID's in commands and in command replys as ID Payloads.
2867 Change affected both client and server side codes.
2869 All ID's sent in SILC network (with execption of ID's in SILC
2870 Packet header) are sent in ID Payload to support variable length
2873 * Server now notifies nick changes and notifies all clients on
2874 the channels about the new nickname (about the new Client ID,
2877 * Implemented CMODE command to change channel modes. Supports all
2878 channel modes defined by the protocol specs except ban and invite
2879 lists. (Also, private channel key mode is supported but support for
2880 setting private channel key in client is missing, thus, this mode
2881 has no effect on client side (except that server requires that the
2882 client uses private channel key and normal channel traffic does not
2885 Also, invite mode works per se, but INVITE command does not work
2886 yet correctly, so you can set channel as invite only channel but
2887 inviting clients to the channel does not work (it is yet to be
2888 thought what's the best way to do it).
2890 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2891 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2892 Implemented CUMODE command to change user's mode on the channel.
2893 Supports all modes defined by the protocol specs.
2895 * Added NAMES command reply to return users modes on the channel.
2897 * Removed unnecessary and slow ciphers from lib/silccrypt.
2899 * Set SO_KEEPALIVE option to connection sockets by default.
2901 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2903 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2904 redefined the Notify Payload into protocol specs.
2906 * Added silc_id_payload_parse_id to get ID directly from raw
2909 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2912 accept searching by Client ID as well.
2914 * Added support for LEAVE and SIGNOFF notify types in client library.
2916 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2917 to parse ID Payload from raw data.
2919 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added flags parameter into silc_ske_assemble_security_properties
2922 function in lib/silcske/silcske.[ch].
2924 * Changed notify client operation to fit better for notify messages
2925 sent by server. The notify payload received from server is now
2926 passed to the application (after parsing it to SilcNotifyPayload).
2927 It is application's responsibility to retrieve the arguments
2928 from the payload and show the message the way it wants. The message
2929 sent by server is implementation specific.
2931 * Changed public keys to comply with the protocol specification.
2932 Old public keys are not supported anymore and are not compatible.
2934 * Removed nickname from Channel Payload as the latest draft removed
2935 it. The client must resolve the nickname from the NAMES command
2936 reply received when it joined the channel.
2938 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2940 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Fixed some errors in protocol specification drafts.
2944 * Created lib/silccore/silcnotify.c to implement Notify Payload
2945 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2946 generic payloads described by protocol specifications. The file
2947 includes implementations for ID Payload and Argument Payload.
2949 * Changed Command Payload implementation to use the new Argument
2950 Payload. Changed command_xxxx_payload to command_payload_xxxx
2951 to comply with SILC coding conventions.
2953 * Added suppport for Argument Payload handling in Notify Payload
2954 implementation as protocol requires it. Added the new support
2955 into server and client lib as well.
2957 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added support for multiple nicknames on same channel. [n] is
2960 added locally to the nickname if there are more than one same
2961 nicknames on the channel.
2963 * Server now sends all nicknames that matched WHOIS request.
2964 Client also shows the list received from server.
2966 * Added TOPIC command to client side. User can now set and show
2967 current topic on channel.
2969 * Added MOTD command to client and server. Also, server sends the
2970 motd when client connects to the server.
2972 * Changed version strings to comply ISO 8601.
2974 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Fixed protocol error handling in client library. It should now
2977 cope even if the SKE fails for some reason.
2979 * Made new protocol specification drafts for submitting to IETF.
2981 * Implemented TOPIC command to server in silcd/command.c.
2983 * Added two new notify types into lib/silccore/silcnotify.h:
2984 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2985 notify nickname change and topic setting/change on a channel.
2987 * API change of command_reply operation in client library. The
2988 application gets now the status type received from server as well.
2990 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2994 * Cras fixed and optimized the packet handling even further and
2995 it should work now. Minor change to the prototype of function
2996 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2998 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Added new function into lib/silcutil/silcschedule.[ch]:
3001 silc_schedule_with_fd to select() a specified fd. The function
3002 returns after timeout expires or data arrives or goes. The
3003 function is used by packet routines to wait that all data is
3004 received from network.
3006 * Fixed data reading from network in lib/silccore/silcpacket.c.
3007 The code now assures that all data is read from the fd and then
3008 continues packet processing. This was a bug fix since the code
3009 used to drop some data in some circumstances.
3011 * Added new function into lib/silcclient/client.[ch]:
3012 silc_client_start_key_exchange to start key exchange after
3013 connection has been established to server. The code internally
3014 now uses this funtion but its main purpose was to provide it
3015 for applications that perform their own connecting. After
3016 application has created a connection it merely calls this
3017 function to start the key exchange between client and server.
3018 The library takes care of everything else after that.
3020 Updated also lib/silcclient/README to explain the usage of
3023 * Do not send to application information that connection has
3024 been established. Application gets notified it by connect
3027 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Applied cras's patch to add silc_schedule_one function. The
3030 function runs scheduler once and returns.
3032 * Fixed the scheduler after cras messed it up. The timeout
3033 handling works now as it's supposed to work.
3035 * Added into lib/silccore/ silcnotify.h to include notify
3036 message types support. Changed silc_server_send_notify*
3037 functions, in server.[ch], to support those new notify types.
3038 Added the support for the notify types into client library,
3039 as well. Added new notify client operation into ops.h in
3042 * Changed silc_server_packet_send_to_channel to send normal
3043 packets instead of just channel message packets. The function
3044 is now used to send the notify packets to channels. It is not
3045 used to send channel message packets anymore, as server never
3048 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3049 va_arg()s as it seems to require it nowadays. I guess, if SILC
3050 is compiled with older va_arg() the new code should work anyway.
3052 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Splitted core library. Core library (lib/silccore) includes
3055 now only SILC protocol specific core (and common) components.
3056 Created new utility library (lib/silcutil) that includes more
3057 generic purpose stuff. The stuff for util library was taken
3058 from the old core library. This was minor and easy split.
3060 * Created SILC Client Library (lib/silcclient) that includes
3061 implementation of the SILC client without user interface. This
3062 was major move from silc/ directory. The code has been changed
3063 so that it is transparent towards the user interface. The
3064 silc/ directory includes now the same user interface as before
3065 and it uses the new client library. Read lib/silcclient/README.
3066 Basicly, the client library performs everything else related
3067 to SILC except user interface handling. Also, configuration
3068 files are considered to be part of user interface and library
3069 does not handle them.
3071 This change also changed a lot of structures, function naming etc.
3072 Most important change was that SilcClientWindow object was
3073 renamed to SilcClientConnection in the client library. Created
3074 also new file lib/silcclient/ops.h. Also added new files
3075 silc/local_command.[ch] and silc/client_ops.[ch].
3077 All these changes were made to make it easier for user interface
3078 designers to create what ever user interface for the SILC client
3081 It is also expected that the server will be moved to lib
3082 directory as well and SILC Server Library will be created;
3083 sometimes in the future.
3085 * Removed Local commands from lib/silccore/silccommand.h as
3086 they are application specific and new client library does not
3087 handle any of those anymore.
3089 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3090 old client implementation in silc/.
3092 * Added support for callback functions in SILC_LOG_* macros.
3093 Application can now set its own callbacks that will be called
3094 instead of using the default functions that will always print
3095 the debug messages to stderr (or stdout). Also, debugging can
3096 now be disabled by setting silc_debug to FALSE and re-enabled by
3097 setting it to TRUE. Note, that logging will still work even
3098 if debugging is disabled.
3100 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3101 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3102 silc_log_reset_debug_callbacks.
3104 * To enable debugging in silc client one must give now -d
3105 option on command line.
3107 * Changed silc_schedule_init to automatically allocate task queues
3108 if they are not allocated before calling it.
3110 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added GMP 3.1 into math library.
3114 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3117 a channel in SILC network. The packet is used by servers and
3118 routers to notify other routers that user has left a channel.
3119 This little feature was missing until now. Added the feature
3120 to protocol specification as well.
3122 Added functions: silc_server_send_remove_channel_user and
3123 silc_server_remove_channel_user into server.[ch].
3125 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3126 lib/silccore/silcpacket.h. However, they are not implemented
3129 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Fixed joining to a channel and sending channel messages
3132 between server and router. The channel message sending should
3133 now work inside a cell.
3135 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Fixed the private message sending between server and router.
3138 The private message sending should now work inside a cell.
3140 * Added silc_server_replace_id into server.[ch] to replace
3141 existing ID in the SILC network.
3143 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3144 and silc_idlist_replace_server_id into idlist.[ch] in server.
3146 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Fixed the server to server connections. Server can again now
3149 connect to router. Router to router connections probably does
3152 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Added dynamic protocol registering support. Now protocols can
3155 registered and unregistered on the fly. Patch by cras.
3157 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added lib/contrib directory to hold routines that some platforms
3160 don't have but are needed by SILC.
3162 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3163 into lin/contrib to provide getopt() and getopt_long() for
3164 those who don't have it.
3166 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added AWAY command to client. When away message is set and
3169 client receives a private message packet the client automatically
3170 replies to the sender with the away message.
3172 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3173 bug seemed to be the cause of recent problems when compiling
3176 * Added version detection support to SKE protocol specification
3177 and added the new changes to the SKE implementation as well.
3178 There were other minor changes in the SKE protocol as well.
3180 Many changes in lib/silcske/silcske.[ch] and in
3181 lib/silcske/payload.[ch].
3183 * Added ^U functionality, clear input line. Patch from cras.
3185 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Mainly small bugfixes on core library. Fixed some debugging
3188 logging and buffer overflow in silclog.c.
3190 * Updated config.sub and config.guess on the distribution tree.
3192 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added command lagging support in server. Client may execute
3195 commands now only once in two seconds.
3197 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Optimized packet reception. MAC computation and checking is now
3200 also more optimized. A lot previously duplicated code is now
3201 used as generic by both client and server.
3203 * Fixed key pair generation in clientutil.c
3205 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Added into lib/silccore/silcbufutil.[ch] new function;
3208 silc_buffer_realloc.
3210 * Moved generic packet sending/encryption functions to
3211 lib/silccore/silcpacket.[ch] from client and server. Some
3212 rewriting of the functions.
3214 * Moved all generic packet reception/decryption functions to
3215 lib/silccore/silcpacket.[ch] from client and server. The
3216 packet processing is now much cleaner in both client and server.
3217 These were major changes in both client and server.
3219 * Created many common functions in server to do packet sending.
3220 Previously code were duplicated a lot, this has been removed
3223 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Rewrote major parts of the ID cache system. Don't know
3226 whether it is better now or not but at least the API is more
3229 * Major rewrite on ID cache stuff on client because of the ID
3230 cache API changes. Added idlist.c to client.
3232 * Also major rewrite on ID cache stuff on server as well.
3233 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3234 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3235 in hand, instead they are all put into the ID cache system now.
3236 All server_idlist_* routines uses ID cache now instead of
3237 traversing its own lists (those lists does not exist anymore).
3238 SilcIDList though still exists. Also, SilcXXXEntry's are
3241 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Finally made the SKE implementation compliant to the protocol
3244 specification. All mp integers are now binary encoded as
3245 opposed being HEX encoded.
3247 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3250 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3251 functions: silc_[encode/decode]_pem. Also added function
3252 silc_encode_pem_file to PEM encode with newlines ('\n') for
3255 * SILC public keys are now encoded either PEM or binary. Same
3256 option is for private keys as well. By default private keys
3257 are binary encoded and public keys PEM encoded. Silly HEX
3258 encoding were removed.
3260 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3261 function to create fingerprints.
3263 * Fixed a bug in SHA1; does not change the original data anymore.
3265 * Partly implemented INFO command on client and server side.
3266 Fixed CLEAR command. Changes to SERVER command; show current
3267 server(s) when giving command without arguments. Added
3268 VERSION command to client.
3270 * Added check to server that unregistered connections cannot
3271 execute commands (unless it is specificly allowed).
3273 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Fixed screen refresh.
3277 * Fixed channel joining bug from client. On some circumstances
3278 client tried to join to a channel it had already joined.
3280 * Added public key verification process into client's protocol.c.
3281 The client now verifies the public key from user and saves
3282 it into ~./silc/serverkeys/ directory.
3284 Added into: clientutil.[ch]: silc_client_verify_server_key.
3286 * Changed SKE protocol's silc_ske_initiator_finish function
3287 to accept callback function that verifies the received public
3288 key. Removed old silc_ske_verify_public_key function.
3290 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3293 silc_pkcs_private_key[_data]_set.
3295 * Made the password and public authentication more cleaner in
3296 server's protocol.c.
3298 * Removed historic and obsolete protocol `channel_auth' from
3299 both client and server.
3301 * Removed wrong way of sending command status messages from
3302 server to client in server's command.c. The old way violated
3303 protocol specification.
3305 Changes to silccore/silccommand.[ch]: removed
3306 silc_command_encode_status_payload -> not needed anymore,
3307 changed silc_command_encode_payload_va to accept extra
3308 argument on variable argument list. The argument type must
3309 now be provided to the function. Also, added new function:
3310 silc_command_encode_reply_payload_va which is same as
3311 normal command_encode_payload_va except command status type
3312 is provided as extra argument.
3314 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Added ~./silc directory handling. The directory includes the
3317 public and private keys for the client.
3319 Added silc_client_check_silc_dir, silc_client_create_identifier
3320 and silc_client_load_keys.
3322 * Implemented SILC protocol compliant public key. Added public
3323 and private key saving to and loading from files.
3325 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3326 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3327 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3328 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3329 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3331 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3332 silc_pkcs_load_[public/private]_key.
3334 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added silc_server_get_route (route.[ch]) to get connection
3337 data for the fastest route for given ID.
3339 * Implemented INVITE command on client and server. The command
3340 were re-defined in the SILC Protocol Specification and the
3341 implementation now complies with the specification.
3343 * Implemented PING command on client and server.
