1 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the configuration data fetching when accepting new
4 connections in the server. Affected file silcd/server.c.
6 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added `sender_entry' argument to the function
9 silc_server_packet_relay_to_channel so that we can check
10 whether some destination actually belongs to the same route
11 the sender belongs (ie, we must not resend the packet to the
12 sender). Affected file silcd/packet_send.[ch].
14 * Added `servername' field to the SilcClientEntry in the server
15 to hold the name of the server where client is from. Affected
16 file is silcd/idlist.h.
18 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Moved the channel message encrypting in the router betwen
21 router connections from silc_server_channel_message to the
22 silc_server_packet_relay_to_channel since we want to check
23 whether we have anybody channel before encrypting anything.
24 Affected files silcd/packet_[receive/send].c.
26 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Fixed the [AdminConnection] server config section to support
29 multiple entries. Affected file silcd/serverconfig.c.
31 * Added support into the server to check the validity of the
32 incoming connection before executing any KE or authentication
35 * The connection configuration is now saved to the KE and
36 connection auth protocol contexts and not fetched anymore in
37 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
39 * The local hosts listenning address and port is also resolved
40 now when starting the server. We want to have the socket object
41 to include the real address and port for the listener. Added
42 new function silc_net_check_local_by_sock into the files
43 lib/silcutil/silcnet.[ch].
45 * Fixed a broadcast bug in server -> do not broadcast if we
48 * Fixed a routing bug. Do not route broadcast packets ever.
49 Broadcast packets must be processed always and not routed since
50 they may be destined to some other host than yourself and thus
51 would get routed without no good reason. Affected file is
54 * Added function silc_server_config_is_primary_route to check
55 whether primary router connection has been configured (a router
56 configuration that we are initiating). If there is not, we
57 will assume that there is only two routers in the SILC network
58 and we will use the incoming router connection as our primary
59 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
61 * Changed the order of the broadcasting. Broadcast _after_ the
62 packet has been processed not before. Affected file is
65 * Fixed a [ClientConnection] parsing bug. The port was never
66 parsed correctly thus resulting to port 0. Affected file
69 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
70 argument and did not set the broadcast packet flag. Affected
71 file silcd/packet_send.c. Fixed same bug in the function
72 silc_server_send_notify as well.
74 * If we receive NEW_ID packet for our own ID in the server, ignore
77 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Removed the nickname from the Private Message Payload.
82 Updated the code and the protocol specs.
84 * Updated protocol specs for submitting to the IETF.
86 * Tweaked the Random Number Generator a bit. Affected file
87 lib/silccrypt/silcrng.c. Exported a new function
88 silc_rng_[global]_add_noise which can be used to add more
91 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
93 * Do not parse packets with different timeout when protocol
94 is active -> may cause problem with rekey. Affected file
97 * When server receives signoff notify it must not create
98 new channel key if the client is on any channels since the
99 sender of the signoff notify will create it.
101 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Added printing of error messages during SKE protocol from the
104 failure packet sent by server during SKE. Affected file
107 * Removed the client's failure_callback handling with timeout
108 and handle it immediately when received.
110 * The SKE library returned wrong type in SUCCESS and FAILURE
111 packets. They must be 32 bit MSB not 16 bit MSB.
113 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Ok, rewrote the logic of the re-key and now it seems to work.
116 I tested it on high traffic with frequent re-keys without
117 problems. Added hmac_receive (and renamed hmac to hmac_send)
118 in SilcClientConnection in lib/silcclient/client.h and
119 in SilcIDListData in silcd/idlist.h. Also, removed the
120 SilcPacketParserContext's cipher and hmac fields as they are
121 not needed anymore and actually caused some problems when
122 the ciphers and hmac's changed underneath the packet parser.
124 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * If re-key protocol is active then process the incoming packets
127 synchronously since we must assure that icoming packets encrypted
128 with the old key is processed before the new keys is set to
129 use. This is true other packets than for REKEY packets.
130 Affected file silcd/server.c. The same was done to client library
131 as well, affected file lib/silcclient/client.c.
133 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Fixed bug in client and server to accept the force send if
136 the packet is send from silc_[server/client]_packet_process
137 function. Otherwise the packets are never delivered, oops.
139 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Disable force sending of packets when REKEY protocol is active.
142 We must assure that no packet is sent directly when rekey is
143 performed. All packets must be sent through packet queue.
144 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
145 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
146 function is silc_[server/client]_packet_send_real to check
149 * Replaced the SIM paths from example config files to
150 /usr/local/modules. Also, make install creates now
151 /usr/local/silc/logs directory to hold all the SILC server
154 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Made the configure.in.pre work on Solaris. Patch by salo.
158 * Made all ciphers compatible with non-x86 machines. Defined
159 CBC mode macros into lib/silccrypt/ciphers_def.h.
161 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
163 * Fixed the make install.
165 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * When MAC computation fails the silc_packet_decrypt returned 0
168 even though it was supposed to return -1. Fixed this. The
169 affected file is lib/silccore/silcpacket.c.
171 * Do not replace the config files in /etc/silc (in make install)
172 if they already exist. Affected file ./Makefile.am.
174 * Do not send re-key packets immediately but through packet queue.
175 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
177 * Changed silc_net_check_host_by_sock to return FALSE if the
178 IP/DNS could not be resolved. Though, it returns the IP address
179 now even if it could not resolve it (but returns also FALSE).
180 Affected file lib/silcutil/silcnet.[ch].
182 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Added silc_pkcs_decode_identifier to decode the public key's
185 identifier. Affected file lib/silccrypt/silpkcs.[ch].
186 Added also silc_pkcs_free_identifier. Added also new context
187 SilcPublicKeyIdentifier.
189 * Added -S option to the silc client. It is used to dump the
190 contents of the specified public key file.
192 * Changed the PKCS api to return the public key length when
193 setting the public key.
195 * Fixed a fatal bug in the public and private key file loading.
196 Affected file lib/silccrypt/silcpkcs.c.
198 * Execute the packet parsing for client with zero (0) timeout
199 if the protocol is active. Affected file silcd/server.c.
201 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Made the key generation options to the silcd program. Added
204 -C option, equivalent to client's option.
206 * Added new [ServerKeys] config section to the server. It
207 configures the server's public and private key.
209 * Defined generic Public Key Payload into the protocol
210 specification to send specific type of public keys and
213 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
214 public key or certificate.
216 * Implemented the GETKEY command to the server and to the
217 client library and on user interface.
219 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Made preliminary `make install' work.
223 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added SilcServerRekey context into silcd/idlist.h.
227 * Added the PFS support as defined in the specification to the
228 SKE protocol. Affected files lib/silcske/*.c.
230 * Added `ske_group' field to the SilcServerRekey context to hold
231 the number of the SKE group that is used with PFS in re-key.
232 Affected file silcd/idlist.h.
234 * Added PFS re-key support to the server. Affected file is
237 * Added silc_protocol_cancel to cancel execution of the next
238 state of the protocol. Affected file is
239 lib/silccore/silcprotocol.[ch].
241 * Added the re-key support with and without PFS to the client
242 library. Re-key is performed once in an hour, by default.
244 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
245 Added silc_client_rekey_callback and silc_client_rekey_final.
246 Affected files are lib/silcclient/protocol.[ch] and
247 lib/silcclient/client.[ch].
249 * Removed the `hmac_key' and `hmac_key_len' fields from the
250 SilcClientConnection structure; not needed. Affected file is
251 lib/silcclient/client.h.
255 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Do not ask whether user wants to use the negotiated private key
258 for private messages, just use it. Affected file is
259 silc/local_command.c.
261 * Added `send_enc_key' and `enc_key_len' fields to the
262 SilcIDListData structure since they are needed in the re-key
263 phase. Affected file is silcd/idlist.[ch].
265 * Implemented the simple re-key protocol into the server.
266 Affected files silcd/server.c and silcd/protocol.[ch]. The
267 re-key will be performed once in an hour, by default.
269 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
270 Added silc_server_rekey, silc_server_rekey_callback and
271 silc_server_rekey_final.
273 * Removed Tunneled flag from the protocol. Updated the code
274 and the specifications.
276 * Adde `pfs' field to the SilcIDListData to indicate whether
277 the PFS is to be performed in the re-key. Affected file is
280 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
283 int64 of at least the xintXX size. If void * is less that 4
284 bytes uint32 * will be used. Defined bool as boolean.
286 * Changed _ALL_ unsigned long and unsigned int to uint32,
287 unsgined short to uint16 in the source tree.
289 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
290 not handle clients that has entry->data.registered == FALSE.
291 They are not in the network anymore. Affected file is
294 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * Implemented the sending of the SERVER_SIGNOFF notify in the
297 server. Affected file is silcd/server.c.
299 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
300 Added also silc_notify_payload_encode_args into the
301 lib/silccore/silcnotify.[ch].
303 * Implemented ther SERVER_SIGNOFF notify handling in the server.
304 Affected file silcd/packet_receive.c.
306 * Implemented the SERVER_SIGNOFF notify handling in the client
307 library. Affected file lib/silcclient/client_notify.c. Also,
308 implemnted the printing of the SERVER_SIGNOFF info to the
309 application. Affected file silc/client_ops.c.
311 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
312 if the deleting was successful. Affected file silcd/idlist.[ch].
314 * Added support for public key authentication in the connection
315 authentication protocol in the client library. Affected file
316 lib/silcclient/protocol.c.
318 * Changed the server's silc_idlist_get_clients_by_* interface
319 to support already allocated array so that new entries may be
320 added to pre-allocated array. Affected file silcd/idlist.[ch].
321 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
324 * All command reply functions in the server now calls the
325 pending command callback even if error occured. This way the
326 error will be delivered to the client as well. Affected files
327 silcd/command.c and silcd/command_reply.c.
329 * Fixed INFO command to return local server's info if no server
330 was provided. Affected file lib/silcclient/command.c.
332 * Removed RESTART command for good. Updated the code and the
335 * Rewrote parts of the task system. It is a bit simpler now.
336 Removed unsued task priorities. The affected files are
337 lib/silcutil/silctask.[ch].
339 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Moved the USERS printing from the library to the application.
342 Affected files lib/silcclient/command.c and silc/client_ops.c.
344 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Added channel key re-key support. The re-key is perfomed
349 only by the router and is done once in an hour. Added `rekey'
350 field to the SilcChannelEntry in the server. Affected files
351 silcd/server.c and silcd/idlist.h.
353 * Added silc_task_unregister_by_context into the file
354 lib/silcutil/silctask.[ch].
356 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added SILC_UMODE_GONE mode to indicate when the client is not
359 present in the SILC network. Added also support to the local
360 command AWAY that will set this mode. Added support of showing
361 "xxx is gone" in WHOIS command. The USERS command shows the
364 * Fixed setting server and router operator privileges in the
365 server's UMODE command. Affected file silcd/command.c.
367 * Merged the SKE KE1 and KE2 payloads into one payload. The
368 new KE payload is equivalent to the old KE2 payload.
370 Cleaned up the SKE Start Payload parsing. It now uses the
371 simple buffer unformatting to do the parsing. A lot faster
374 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
375 to the SKE that is used to indicate whether both of the SKE
376 parties should perform authentication. By default only the
377 responder performs authentication. By setting this flag also
378 the initiator must do authentication. By default it is unset
379 since in normal SKE case, client to server connection, only
380 the responder should do authentication. When doing SKE between
381 two clients both should perform authentication. Updated the
382 code and the protocol specs.
384 * A little fix to IDENTIFY command in the server. Search the
385 client first by hash not nickname. Affected file is
388 * Fixed the silc_client_close_connection to support closing
389 the client to client connections wihtout deleting too much
390 data. Affected file lib/silcclient/client.c.
392 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
393 are received if protocol used to be active but is not anymore
394 the application would crash due to NULL pointer dereference.
395 Affected files silcd/server.c and lib/silcclient/client.c.
397 * Added `hash' field to the SilcClientConnection to include
398 the hash function negotiated in the SKE protocol.
400 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
401 to set the channel founder authentication data. A client can
402 claim the founder rights later by providing the authentication
403 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
404 This way the channel founder can regain the channel founder
405 privileges even it is left the channel. This works only on
406 local server and the client must be connected to the same
407 server to be able to regain the founder rights. Updated the
408 protocol specs accordingly.
410 Added support to the CMODE command in the client to set the
411 founder auth data. Read the README to see how to set it.
413 Added support to the CUMODE command to claim the founder
414 rights. Read the README to see how to do it.
416 Added support for the founder authentication to the Channel
417 Entry in the server. Affected file silcd/idlist.h.
419 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
420 server's CMODE command. Affected file silcd/command.c.
422 * Added the following new functions into lib/silccore/silcauth.[ch]:
423 silc_auth_get_method and silc_auth_get_data.
425 * The server now saves the remote hosts public key to the
426 SilcIDListData pointer. Affected file silcd/protocol.c.
428 * The normal server now does not remove the channel entry from
429 the cache if the founder authentication data is set. It used
430 to remove it if the founder was the last one on the channel on
431 the server and left the channel. The auth data is saved and
432 if the channel is re-joined later the old entry is used with
433 the old auth data. Affected files silcd/command_reply.c and
436 * Removed the `pkcs' field from the SilcIDListData structure
437 in the server; it is not used. Affected file silcd/idlist.h.
439 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Fixed packet processing on slow links. Partial packets were
442 never re-processed because the incoming data buffer was cleared
443 by the application. Application must not directly clear the
444 sock->inbuf, the packet processing routines handle it. Fixed
445 this in client library and in server.
447 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Fixed the WHOIS and IDENTIFY send reply function to really
450 check whether to send list or just one entry. Affected file
453 * Cleaned up the LEAVE command's channel key distribution. The
454 affected file silcd/command.c.
456 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
457 can enforce the channel mode as well. In that case the ID
458 includes the ID of the server. The code now enforces the
459 mode change if the router have different mode than the server.
461 * The notify client operation with CMODE_CHANGE notify can now
462 return NULL client_entry pointer if the CMODE was not changed
463 by client. Application must check for this.
465 * Added <Server ID> argument to INFO command to support server
466 info fetching by Server ID.
468 * Added silc_server_announce_get_channel_users to get assembled
469 packets of channel users of the specified channel. Affected
470 file silcd/server.[ch].
472 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
473 was freed underneath the ID Cache.
475 * Re-announce clients when the server received CHANNEL_CHANGE
476 notify from the router. Affected file silcd/packet_send.c.
478 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
481 crashed since it did not handle the fact that there is no cipher
482 called "3" and didn't check the error condition. Now fixed.
484 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
485 flag. It can be used to send message requests.
487 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Implemented the RESTART command in the client.
491 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
492 notice type messages. Added notice printing to the user
495 * The channel keys are not re-generated if the channel's mode
496 is PRIVKEY, ie private key on the channel exists. Affected
497 files silcd/server.c and silcd/command.c.
499 * Fixed a little bug in channel message delivery when channel
500 private keys are set in the server. Affected file is
503 * Changed the setting on channel->on_channel = TRUE from the
504 silc_client_save_channel_key to the JOIN command reply. The
505 key payload is not received if the private channel key is set.
506 Affected file lib/silcclient/command_reply.c and the
507 lib/silcclient/client_channel.c.
509 * When the CMODE_CHANGE notify is sent and the channel private
510 key mode is removed the channel key must be re-generated in
511 other cells as well. Added this support for the router in the
512 silcd/packet_receive.c.
514 * Added new local command NOTICE to send notice message on
515 channel. Affected file silc/local_command.[ch].
517 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Added new local command ME to the client. It is used to send
520 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
521 some action. Affected file silc/local_command.[ch].
523 * Changed channel_message and private_message client operations
524 to deliver the message flags to the application. Added also
525 the `flags' arguments to the silc_client_send_channel_message
526 and silc_client_send_private_message functions. Affected file
529 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Redefined the Private Message Payload to support private message
532 keys and to support the new private message flags. Updated
533 the protocol specs. Flags makes it possible to have for example
536 * Added new type SilcPrivateMessagePayload and defined an API
537 for it in the lib/silcclient/silcprivate.[ch].
539 * Tested private message private keys successfully. Tested the
540 private message key set, unset and list commands with the new
543 * Redefined the Channel Message Payload to include the channel
544 message flags (equal with private message flags) to support
545 for example CTCP style messages.
547 * Defined some of the message (for channel and private message)
548 flags. Updated the protocol specs and added the flags to the
549 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
551 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Added SilcKeyAgreementStatus type to the key agreement routines
554 to indicate the current status and error if one occured.
555 The status types are defined in the lib/silcclient/silcapi.h.
557 * Added new local command KEY that is used to set and unset private
558 keys for channels, set and unset private keys for private messages
559 with remote clients and to send key agreement requests and
560 negotiate the key agreement protocol with remote client. The
561 key agreement is supported only to negotiate private message keys,
562 it currently cannot be used to negotiate private keys for channels,
563 as it is not convenient for that purpose.
565 * Fixed a minor pending callback setting bug in the function
566 silc_client_get_client_by_id_resolve, now the function works.
567 Affected file lib/silcclient/idlist.c.
569 * Added function silc_net_get_local_port to get local bound
570 port by socket. Added to lib/silcutil/silcnet.[ch].
572 * Added `sockets' and `sockets_count' fields to the SilcClient
573 object. They hold the sockets of the listenning sockets in
574 the client. Listenning sockets may be for example the key
575 agreement server. Affected file lib/silcclient/client.[ch].
576 Added functions the silc_client_add_socket and the
577 silc_client_del_socket. They are exported to the application
580 * Added ~./silc/clientkeys to support other client's public keys.
582 * Renamed verify_server_key client operation to verify_public_key
583 and added one argument to indicate the type of the connection
584 (server, client etc.).
586 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Added silc_server_connection_auth_request to handle the
589 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
590 silcd/packet_receive.[ch].
592 * Added silc_server_send_connection_auth_request into the
593 silcd/packet_send.c to send the connection auth request packet.
595 * Cleaned up the silcd/protocol.c a bit and fixed some memory
598 * Fixed the public key authentication in responder side in the
599 server. The `auth_data' pointer includes the SilcPublicKey
600 not the path to the public key. Affected file silcd/protocol.c.
602 * Implemented the public key authentication in the initiator side
603 in the server. Affected file silcd/protocol.c.
605 * Removed the [RedirectClient] config section from the server
606 configuration. Is not needed and I don't want to implement it.
608 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Cleaned up the CMODE command in the server. It now works
611 correctly and supports all the modes defined in the protocol.
612 Affected file is silcd/command.c.
614 * Added `hmac_name' field to the SilcChannelEntry in the server
615 to hold the default HMAC of the channel. It can be set when
616 creating the channel (with JOIN command). Affected files
619 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
620 type to indicate the change of the current cipher and hmac
621 on the channel. Client can safely ignore the <cipher> argument
622 (if it chooses to do so) since the CHANNEL_KEY packet will
623 force the channel key change anyway. The <hmac> argument is
624 important since the client is responsible of setting the new
625 HMAC and the hmac key into use.
627 * Fixed the CMODE command in the client library as well.
629 * Tested CMODE command in router environment successfully.
631 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Show the version of the remote client (or server) when connecting
634 to the server. It is logged to the log file. Affected file
637 * Fixed the KILLED notify handling in the client library. The
638 client must be removed from all channels when receiving the
641 Also, do not remove the client entry when giving the KILL
642 command but when the KILLED notify is received.
644 * Removed silc_idlist_find_client_by_nickname from the server.
645 Not needed anymore. Affected files silcd/idlist.[ch].
647 * Implemented the CHANNEL_CHANGE notify type handling to the
648 server. Affected file silcd/server.c.
652 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

655 notify between routers.
657 * Implemented the INVITE command correctly to the server.
659 * Implemented the INVITE notify type handling in the server.
661 * Implemented the INVITE command to the client library and on the
664 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
666 * Added function silc_server_get_client_resolve to find the
667 client entry by ID from all ID lists and then resolve it
668 (using WHOIS) if it cannot be found. Affected file is
671 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Implemented the BAN command to the client library.
675 * The JOIN command in the server now checks the invite list
678 * Changed the silc_command_reply_payload_encode_va and the
679 silc_command_payload_encode_va to support that if argument is
680 NULL it ignores and checks the next argument. Affected file
681 lib/silccore/silccommand.c.
683 * Added silc_server_send_notify_ban to send the BAN notify
684 type between routers.
686 * Chaned the silc_notify_payload_encode to support that if
687 argument is NULL it ignores and checks the next argument.
688 Affected file lib/silccore/silcnotify.c.
690 * Tested ban lists in router environment successfully.
692 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Implemented BAN command to the server, in silcd/command.[ch].
696 * Removed the BAN and INVITE_LIST modes from the CMODE command
699 * Added function silc_string_match to regex match two strings.
700 Affected files lib/silcutil/silcutil.[ch].
702 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Redefined parts of the SilcChannelEntry in the server to support
705 the new ban and invite lists.
707 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Redefined the INVITE command. The same command can be used to
710 invite individuals to the channel but also to manage the invite
711 list of the channel (to add to and remove from the invite list).
712 Updated the protocol specs.
714 * Added new command SILC_COMMAND_BAN that can be used to manage
715 the ban list of the channel. Updated the protocol specs.
717 * Removed the channel modes: the SILC_CMODE_BAN and the
718 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
719 in the CMODE command. The equivalent features are now available
720 using INVITE and BAN commands. Updated the protocol specs.
722 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
723 in the network about change in the current ban list. The notify
724 type is not used by the client.
726 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
727 support the invite lists.
729 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Added new function silc_string_regexify that converts string
732 including wildcard characters into regex string that can
733 be used by the GNU regex library. Added into the file
734 lib/silcutil/silcutil.[ch].
736 Added silc_string_regex_combine to combine to regex strings
737 into one so that they can be used as one regex string by
738 the GNU regex library. Added into the file
739 lib/silcutil/silcutil.[ch].
741 Added silc_string_regex_match to match two strings. It returns
742 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
744 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Imported GNU regex to the soruce tree into lib/contrib.
747 Fixed some compiler warning from the regex.c.
749 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Fixed MOTD command in the server to work in router environment.
753 * Fixed the MOTD command in the client library to support
754 the server argument in the command.
756 * Added `nickname_len' argument to the silc_idlist_add_client
757 in the server, as the `nickname' argument may be binary data
760 * Added silc_idlist_get_channels to return all channels from
763 * Implemented LIST command to the server. Affected file is
766 * Implemented the LIST command to the client library and on the
769 * Added [<user count>] argument to the LIST command reply.
770 With private channels the user count is not shown.
772 * Updated TODO and README.
774 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * The client entry's data.registered must be TRUE even with
777 global client entry on global client list. The data.registered
778 is used to check whether the client is anymore in the network,
779 for example with WHOWAS command so it must be valid.
781 * Fixed the WHOWAS command in the server. It now actually works
782 in router environment. Added function into silcd/command_reply.c
783 silc_server_command_reply_whowas_save.
785 * Added silc_idlist_purge function to the silcd/idlist.c
786 to periodically purge the ID Cache.
788 * Fixed INFO command in the server. It works now in router
789 environment. Added <server name> argument to the INFO command
790 reply. Updated the protocol specs.
792 * Fixed minor bug in silc_idcache_purge to not purge if the
793 expire value is zero.
795 * Fixed various bugs in WHOIS and IDENTIFY command handling as
796 they were buggy because of the WHOWAS information.
798 * Fixed local command MSG to handle the async resolving of
799 the remote client properly. It used to fail the first MSG.
800 Affected file silc/local_command.c.
802 * Added `data_len' field to SilcIDCache context.
804 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Update TODO. Todo in commands in the server.
808 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
811 used by routers as broadcast packet to inform other routers
812 about the changed user mode.
814 Implemented the notify handling in the server. Affected file is
815 silcd/packet_receive.c. Added the function
816 silc_server_send_notify_umode to the silcd/packet_send.[ch].
818 * Added new generic Channel Payload and deprecated the New Channel
819 Payload. The New Channel Payload is now the generic Channel
822 * Added new argument `mode' to the silc_server_send_new_channel
823 as it is required in the Channel Payload now.
825 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
826 and created a new and real SilChannelPayload to represent the
827 new generic Channel Payload. Implemented the encode/decode
828 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
830 * Added silc_server_get_client_channel_list to return the list
831 of channels the client has joined for WHOIS command reply.
832 Affected file silcd/server.[ch].
834 * Implemented the channel list sending in the WHOIS command reply
835 in server and in the client.
837 Implemented the channel list displaying on the user interface
838 as well. Affected file silc/client_ops.c.
840 * Added silc_channel_payload_parse_list to parse list of Channel
841 Payloads. It returns SilcDList list of SilcChannelPayloads.
842 Client for example can use this function to parse the list of
843 channels it receives in the WHOIS command reply. The caller
844 must free the list by calling silc_channel_payload_list_free.
845 Affected files lib/silccore/silcchannel.[ch].
847 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Added one new argument <user mode> to the WHOIS command reply
850 to return the mode of the user in SILC. Updated the protocol
853 Implemented it to the server and client.
855 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Fixed the mode printing on the user interface on joining.
858 Affected file silc/client_ops.c.
860 * Implemented the UMODE command and user modes in general to the
861 client library and to the user interface.
863 * Implemented the UMODE command to the server.
865 * The server now sends UNKNOWN_COMMAND error status if client sends
866 unknown command. Affected file silcd/command.c.
868 * All server commands now handle the command identifier the right
869 way when sending the command reply to the client. The client can
870 use to identify the command replies with the identifier.
872 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Added silc_server_get_client_route to resolve the route to
875 the client indicated by the client ID. Affected file is
878 * Added silc_server_relay_packet as general function to relay
879 packet to arbitrary destination. This deprecates functions
880 like _send_private_message_key, _relay_notify etc. Affected
881 file is silcd/packet_send.[ch].
883 Removed silc_server_send_key_agreement,
884 silc_server_send_private_message_key and
885 silc_server_packet_relay_notify functions from the file
886 silcd/packet_send.[ch].
890 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
891 server. Affected file silcd/packet_receive.[ch].
893 * Implemented the KILL command to the client. Implemented the
894 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
895 Affected files lib/silcclient/command[_reply].c and
896 lib/silcclient/client_notify.c. Implemented the KILL notify
897 printing in the user inteface.
899 * Fixed a lot silc_parse_nick memory leaks from the client
900 library in the file lib/silcclient/command.c.
902 * Changed the silc_server_send_notify_on_channels's `sender'
903 argument from SilcSocketConnection to SilcClientEntry to
904 check the sender as entry and not as connection object and not
905 to send to the client provided as argument. The affected file
906 is silcd/packet_send.[ch].
908 * The notify packets that are destined directly to the client used
909 to not to be processed by the server. Now changed that and the
910 server processes all notify packets. After relaying the packet
911 to the client the notify packet is processed in the server.
913 * The silc_server_free_client_data now checks whether there is
914 pending outgoing traffic for the client and purges the data to
915 the network before removing the client entry.
917 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
920 an client is killed from the SILC Network. Updated the protocol
923 Added new function silc_server_send_notify_killed to the
924 silcd/packet_send.[ch].
926 * Added function silc_server_packet_relay_notify to relay notify
927 packets that are destined directly to a client. In this case
928 the server does not process the notify packets but merely relays
929 it to the client. Affected file silcd/packet_send.[ch].
931 Added also silc_server_packet_process_relay_notify to check
932 whereto relay the notify. Affected file is
933 silcd/packet_receive.[ch].
935 * Implemented the KILL command to the server.
939 * Added the backup schema desgined last fall to the protocol
940 specs for everyone to see. The specification is in the
941 *-spec-xx.txt draft and the packet type definitions for the
942 backup routers is in *-pp-xx.txt draft. Thusly, added also
943 new packet type SILC_PACKET_CELL_ROUTERS.
945 * A big security problem in the implementation discovered. The
946 signoff of an client did not cause new channel key generation
947 which it of course should've done. The channel keys must be
948 always re-generated when client leaves (or signoffs) the channel.
949 The silc_server_remove_from_channels funtion now handles
950 the channel key re-generation.
952 * Added `sender' argument to the silc_server_send_notify_on_channels
953 to not to send the client provided as argument. Affected file
954 silcd/packet_send.[ch].
956 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Implemented OPER and SILCOPER commands into the server and
961 * Added silc_auth_verify and silc_auth_verify_data to verify
962 the authentication directly from the authentication payload.
963 It supports verifying both passphrase and public key based
964 authentication. Affected file lib/silccore/silcauth.[ch].
966 * Added `hash' field to the SilcIDListData structure. It is the
967 hash negotiated in the SKE protocol. Affected file is
970 * Slight redesigning of the SilcAuthPayload handling routines.
971 Do not send SilcPKCS but SilcPublicKey as argument.
973 * Implemented the public key authentication support to the
974 serverconfig. The public key is loaded from the provided path
975 and saved as authentication data to void * pointer. Thus,
976 changed the unsigned char *auth_data to void *auth_data;
978 * Fixed SHUTDOWN command to send the reply before the server
979 is shutdown. :) Affected file silcd/command.c.
981 * Fixed fatal bug in CONNECT command. The hostname was invalid
982 memory and server crashed. Affected file silcd/command.c.
984 * Fixed fatal bug in CLOSE command. The server_entry became
985 invalid but was referenced later in the command. Affected file
988 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Fixed fatal bug in failure packet handling. Server ignored
991 the failure and thus crashed when it came.
995 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
998 that the command may be executed only once in (about) 2 seconds.
999 The old SILC_CF_LAG flag is same but allows command bursts up
1000 to five before limiting.
1002 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1003 server code. Various commands now includes the CF_LAG_STRICT
1004 flag to disallow any kind of miss-use of the command.
1006 * Fixed the silc_buffer_unformat to not to allocate any data
1007 if the length of the data is zero. It used to allocate the
1008 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1010 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Changed the format of AdminConnection configuration section
1013 in the server. Added username of the admin to the format.
1014 Affected files silcd/serverconfig.[ch].
1016 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1017 to return admin configuration data by host, username and/or
1020 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Implemented WHOWAS command to the server. Added the functions:
1024 silc_server_command_whowas_parse,
1025 silc_server_command_whowas_send_reply,
1026 silc_server_command_whowas_from_client and
1027 silc_server_command_whowas_from_server
1029 * Added <Client ID> argument to the WHOWAS command reply. Updated
1030 the protocol specs accordingly.
1032 * Implemented WHOWAS command and command_reply to the client
1035 Implemented the WHOWAS printing on the user interface.
1037 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Added new argument to the WHOWAS command reply, the real name.
1040 It is an optional argument. Updated the protocol specs.
1042 * Added SilcIDCacheDestructor callback that is registered when
1043 the SilcIDCache is allocated. The callback is called when
1044 an cache entry in the ID Cache expires, or is purged from the
1045 cache. Added into lib/silccore/idcache.[ch].
1047 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1048 to destruct the client entries when the cache entry expires.
1049 Other ID Cache's in server and in the client library ignores
1052 * If the ID Cache entry's `expire' field is zero then the entry
1053 never expires. Added boolean `expire' argument to the
1054 silc_idcache_add function in the lib/silccore/idcache.[ch].
1055 If it is TRUE the default expiry value is used.
1057 * Added silc_server_free_client_data_timeout that is registered
1058 when client disconnects. By default for 5 minutes we preserve
1059 the client entry for history - for WHOWAS command.
1061 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Added support to the server to enforce that commands are not
1064 executed more than once in 2 seconds. If server receives
1065 commands from client more frequently, timeout is registered
1066 to process the commands. Affected file silcd/command.c.
1067 Added new function silc_server_command_process_timeout.
1069 * Changed NICK_NOTIFY handling in client library to check that
1070 if the client's nickname was changed, so there is no need to
1071 resolve anything from the server.
1073 * Removed error printing from the WHOIS and IDENTIFY commands.
1074 If error occurs then it is ignored silently in the client library.
1075 The application, however, may map the received error to
1076 human readable error string. The application currently maps
1077 the NO_SUCH_NICKNAME error to string.
1079 * Made the command status message public to the application. Moved
1080 them from lib/silcclient/command_reply.c to
1081 lib/silcclient/command_reply.h. The application can map the
1082 received command status to the string with the
1083 silc_client_command_status_message function.
1085 * Added check to the server to check that client's ID is same
1086 as the Source ID in the packet the client sent. They must
1089 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Added dist-bzip hook to the Makefile.am to make bzip2
1092 compressed distributions.
1094 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Server now enforces the maximum length for the nickname and
1097 the channel as protocol specification dictates. 128 bytes for
1098 nickname and 256 bytes for channel name.
1100 * Moved the WHOIS printing to the application. The client libary
1101 does not print out the WHOIS information anymore, the application
1102 must do it. Renamed silc_client_command_reply_whois_print to
1103 the silc_client_command_reply_whois_save.
1105 The client's idle time is also sent to the application now, and
1106 the idle is shown on screen.
1108 * Added silc_client_command_reply_identify_save to save the
1109 received IDENTIFY entries.
1111 * Do not check for channel private keys in message sending and
1112 reception if the channel does not have the PRIVKEY mode set.
1113 Affected file lib/silclient/client_channel.c.
1115 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1118 just surfaced after chaning the JOIN procedure.
1120 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added silc_client_get_clients_by_list to get client entries
1123 from Client ID list, that is returned for example by JOIN
1124 and USERS command replies. The application should use this
1125 function for example when JOIN command reply is received to
1126 resolve the clients already on the channel (library does not
1127 do that anymore as USERS command reply is not used in the JOIN
1128 procedure anymore). Affected files lib/silcclient/silcapi.h and
1129 lib/silcclient/idlist.c.
1131 * JOIN command reply and USERS command reply returns now SilcBuffer
1132 pointers instead of unsigned char pointers when returning
1133 the client list and mode list.
1135 * Added <Client ID> argument to the JOIN command reply, mainly
1136 for the server to identify for which client the command was
1137 originally sent. Updated protocol specs accordingly.
1139 * Added SilcDlist private_key pointer to the SilcChannelEntry
1140 in the client to support the channel private keys. Affected
1141 file is lib/silcclient/idlist.h.
1143 * Added SilcChannelPrivateKey argument to the function
1144 silc_client_send_channel_message so that application can choose
1145 to use specific private ke if it wants to. If it is not provided,
1146 the normal channel key is used, unless private keys are set.
1147 In this case the first (key that was added first) is used
1148 as the encryption key.
1150 * Implemented the support for channel private key handling.
1151 Implemented the following functions:
1153 silc_client_add_channel_private_key,
1154 silc_client_del_channel_private_keys,
1155 silc_client_del_channel_private_key,
1156 silc_client_list_channel_private_keys and
1157 silc_client_free_channel_private_keys
1159 Affected file lib/silcclient/client_channel.c.
1161 * Added the support for the private keys in the channel message
1162 sending and encryption and in the message reception and
1163 decryption. Affected funtions are
1164 silc_client_send_channel_message and silc_client_channel_message.
1166 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Added SKE's key verify callback to the client library's
1169 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1171 * Removed the statement that server (or router) must send USERS
1172 command reply when joining to the channel so that the client
1173 knows who are on the channel. Instead, the client list and
1174 client's mode list is now sent in the JOIN command reply to the
1175 client who joined channel. This is better solution.
1177 * Added function silc_server_get_users_on_channel and function
1178 silc_server_save_users_on_channel to the silcd/server.[ch].
1180 * Removed function silc_server_command_send_users from the
1183 * Do not show topic on the client library anymore. The topic is
1184 sent in the command reply notify to the application and the
1185 application must show the topic now.
1187 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Added client searching by nickname hash into the IDENTIFY and
1190 WHOIS commands in the server as they were clearly missing from
1191 them. Affected file is silcd/command.c.
1193 * Fixed a bug in private message receiving in the client library.
1194 The remote ID was freed and it wasn't supposed, now it is
1197 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Minor fix to the channel payload; allocate the data area, as it
1200 needs to be of specific length.
1202 * If the key agreement port is zero then the operating
1203 system will define the bound port. Affected files are
1204 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1206 * Added new function silc_channel_payload_decrypt into the file
1207 lib/silccore/silcchannel.[ch].
1209 * Moved the channel message etc, check from silc_packet_decrypt
1210 to applications. The library calls now a generic
1211 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1212 when the packet is either normal or special. This was done to
1213 allow more wide range of checking that was not allowed when
1214 the code was in library. Now applications can do virtually any
1215 checks to the packet and return to the library the decision how
1216 the packet should be processed. Affected files are
1217 lib/silccore/silcpacket.[ch].
1219 Added silc_server_packet_decrypt_check to the server and
1220 silc_client_packet_decrypt_check to the client library.
1222 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1223 to send with specified source and destination information.
1225 * Channel message delivery between routers was broken after the
1226 channel key distribution was fixed earlier. The channel key
1227 was used be to distributed to other routers as well which is not
1228 allowed by the protocol. Now this is fixed and channel keys
1229 really are cell specific and the channel message delivery between
1230 routers comply with the protocol specification.
1232 * Fixed various commands in server to check also the global list
1233 for the channel entry and not just the local list. The affected
1234 file silcd/command.c.
1236 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Added assert()s to buffer formatting and unformatting routines
1239 to assert (if --enable-debug) when error occurs. Affected
1240 file: lib/silcutil/silcbuffmt.c.
1242 * Changed to auto-reconnect to check whether the remote host is
1243 router and register the re-connect timeout if it is. It used
1244 to check that whether we are normal server, but router must do
1245 auto-reconnect with another router as well. Affected file
1248 * Removed the [<key len>] option from CMODE command as the cipher
1249 name decides the key length, nowadays. See the defined ciphers
1250 from the protocol specification.
1252 * Added [<hmac>] option to the CMODE command to define the HMAC
1253 for the channel. Added SILC_CMODE_HMAC channel mode.
1255 * Added [<hmac>] option for the JOIN command so that user can
1256 select which HMAC is used to compute the MACs of the channel
1259 * Added Hmac field to the Channel Message Payload. The integrity
1260 of plaintext channel messages are now protected by computing
1261 MAC of the message and attaching the MAC to the payload. The
1262 MAC is encrypted. Now, it is clear that this causes some
1263 overhead to the size of the packet but rationale for this is that
1264 now the receiver can verify whether the channel message decrypted
1265 correctly and also when private keys are set for the channel the
1266 receiver can decrypt the packet with several keys and check from
1267 the MAC which key decrypted the message correctly.
1269 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1270 lib/silccrypt/silccipher.[ch].
1272 * Added silc_hash_len to return the digest length into the
1273 lib/silcrypt/silchash.[ch].
1275 * Rewrote parts of Silc Channel Payload interface in the
1276 lib/silccore/silcchannel.[ch]. The encode function now also
1277 encrypts the packet and parse function decrypts it.
1279 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Fixed a minor formatting bug in the SKE's key material processing.
1282 It actually might have processed the keys wrong way resulting
1285 * Redefined the mandatory HMAC algorithms and added new algorithms.
1286 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1287 and hmac-md5 truncated to 96 bits. The mandatory is now
1288 hmac-sha1-96. Rest are optional (including the one that used
1289 to be mandatory). Rationale for this is that the truncated HMAC
1290 length is sufficient from security point of view and can actually
1291 make the attack against the HMAC harder. Also, the truncated
1292 HMAC causes less overhead to the packets. See the RFC2104 for
1295 * Added new [hmac] configuration section. The SKE used to use
1296 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1297 is of course wrong. The official names that must be proposed in
1298 the SKE are the ones defined in the protocol specification
1299 (hmac-sha1-96 for example). The user can configure any hmac
1300 using any hash function configured in the [hash] section. At
1301 least, the mandatory must be configured.
1303 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1305 * Added HMAC list to the SKE proposal list. It has now both
1306 hash algorithm list and HMAC list. This makes the protocol
1307 incompatible with previous versions. The SKE now seems to work
1308 the way it is supposed to work, for the first time actually.
1310 * Defined plain Hash algorithms to the protocol specification.
1313 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Implemented support for key agreement packets into the server.
1316 Added functions silc_server_key_agreement and
1317 silc_server_send_key_agreement. Other than these functions,
1318 server has nothing to do with this packet.
1320 * Added support for private message key packets into the server.
1321 Added functions silc_server_private_message_key and
1322 silc_server_send_private_message_key.
1326 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1327 called in the protocol's final callback instead in the END
1328 protocol state. This makes a little more sense and in the same
1329 time in client we can use the same protocol routines for normal
1330 key exchange and to key agreement packet handling as well.
1332 * Added to both client's and server's KE protocol context the
1333 SilcSKEKeyMaterial pointer to save the key material. We will
1334 bring the key material to the protocol's final callback by doing
1335 this. The final callback must free the key material.
1337 * Added SKE's packet_send callback into client's KE protocol
1338 context so that the caller can choose what packet sending function
1339 is used. This way we can use different packet sending when
1340 doing normal SKE when doing key agreement packet handling (in
1341 the key agreement packet handling we do not want to encrypt
1344 * Implemented the responder side of the key agreement routines
1345 in the client. The client can now bind to specified port and
1346 accept incoming key negotiation. The key material is passed
1347 to the application after the protocol is over.
1349 * Implemented the processing of incoming Key Agreement packet
1350 in the client. Added function silc_client_key_agreement to
1353 * Implemented the intiator side of the key agreement routines
1354 in the client. The client can now initiate key agreement with
1355 another remote client. The key material is passed to the
1356 application after the protocol is over.
1358 * Created client_keyagr.c to include all the key agreement
1361 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1362 SILC_TASK_CALLBACK except that it is not static.
1364 * Created client_notify.c and moved the Notify packet handling
1365 from the client.[ch] into that file.
1367 * Created client_prvmsg.c and moved all private message and
1368 private message key routines from the client.[ch] into that file.
1370 * Create client_channel.c and moved all channel message and
1371 channel private key routines from the client.[ch] into that file.
1373 * Changed silc_client_get_client_by_id_resolve to resolve with
1374 WHOIS command instead of IDENTIFY command, in the file
1375 lib/silclient/idlist.c.
1377 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1379 * Implemented the SKE's responder side to the Client library.
1381 * When FAILURE is received to the protocol do not trust it
1382 blindly. Register a timeout to wait whether the remote closes
1383 the connection as it should do it, only after that process the
1384 actual failure. This was changed to both client and server.
1386 * Added client_internal.h to include some of the structures
1387 there instead of client.h in lib/silcclient/.
1389 * Added function silc_task_unregister_by_callback to unregister
1390 timeouts by the callback function.
1392 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Some "Incomplete WHOIS info" errors has been appearing on the
1395 log files. Took away the entry->userinfo check from WHOIS
1396 reply sending. The entry->userinfo is now " " if client did not
1397 provide one. I thought this was fixed earlier but something
1398 is wrong still. Let's see if the error still appears.
1400 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed a minor bug in the login when the channel key is
1403 re-generated in the server. It used to generate the key in
1404 wrong order and thus caused problems in the channel traffic.
1406 * Fixed a minor bug in channel key distsribution after
1407 KICK command. The key was not sent to the router even though
1410 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Added silc_ske_process_key_material_data as generic routine
1413 to process any key material as the SILC protocol dictates. The
1414 function is used by the actual SKE library but can be used by
1415 applications as well. This relates to the private message keys
1416 and the channel private keys since they must be processed the
1417 same way the normal SILC session keys. The protocol dictates
1418 this. Affected files: lib/silcske/silcske.[ch].
1420 Added also silc_ske_free_key_material to free the
1421 SilcSKEKeyMaterial structure.
1423 * Defined silc_cipher_set_key function to set the key for
1424 cipher without using the object's method function. The affected
1425 files: lib/silccrypt/silccipher.[ch].
1427 * Implemented silc silc_client_add_private_message_key,
1428 silc_client_add_private_message_key_ske,
1429 silc_client_del_private_message_key,
1430 silc_client_list_private_message_keys and
1431 silc_client_free_private_message_keys functions in the
1434 Added functions silc_client_send_private_message_key to send
1435 the Private Message Key payload and silc_client_private_message_key
1436 to handle incoming Private Message Key payload.
1438 * Added Cipher field to the Private Message Key payload to set
1439 the cipher to be used. If ignored, the default cipher defined
1440 in the SILC protocol (aes-256-cbc) is used.
1442 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Removed lib/silcclient/ops.h file.
1446 Redefined parts of the SILC Client Library API. Created new
1447 file silcapi.h that deprecates the ops.h file and defines the
1448 published Client Library API. Defined also private message key
1449 API and channel private key API into the file.
1451 This is the file that the application must include from the
1452 SILC Client Library. Other files need not be included by
1453 the application anymore.
1455 * Added new key_agreement client operation callback and also
1456 defined the Key Agreement library API for the application.
1458 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1461 is used by clients to request key negotiation between another
1462 client in the SILC network. If the negotiation is started it
1463 is performed using the SKE protocol. The result of the
1464 negotiation, the secret key material, can be used for example
1465 as private message key.
1467 Implemented the Key Agreement payload into the files
1468 lib/silccore/silauth.[ch].
1470 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Redefined ciphers for the SILC protocol. Added some new ciphers
1473 and defined the key lengths for the algorithms. Changed the
1474 code accordingly. The default key length is now 256 bits.
1476 * Fixed SKE key distribution function silc_ske_process_key_material
1477 when the key length is more than 128 bits. The default key
1478 length in SILC is now 256 bits.
1480 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1481 to indicate unsupported algorithm.
1483 * Renamed rijndael.c to aes.c and all functions as well.
1485 * Fixed a long standing channel key setting bug in client library.
1486 Weird that it has never surfaced before.
1488 * Fixed bug in channel deletion. If the entire channel is removed
1489 then it must also delete the references of the channel entry
1490 from the client's channel list as the client's channel entry and
1491 the channel's client entry share same memory.
1493 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * Implemented CONNECT and SHUTDOWN commands in the client.
1497 * Implemented CLOSE command to the client.
1499 * Added the function silc_idlist_find_server_by_name into the
1500 files silcd/idlist.[ch].
1502 Added the function silc_idlist_find_server_by_conn into the
1503 files silcd/idlist.[ch].
1505 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1507 * DIE command was renamed to SHUTDOWN. Updated the both code
1510 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1511 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1513 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1516 * Added function silc_server_create_connection function to create
1517 connection to remote router. My server implementation actually
1518 does not allow router to connect to normal server (it expects
1519 that normal server always initiates the connection to the router)
1520 so the CONNECT command is only good for connecting to another
1523 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1526 or some other client was kicked from the channel.
1528 Implemented the handling of the notify type to both client
1531 Implemented silc_server_send_notify_kicked to send the KICKED
1532 notify. It is used to send it to the server's primary router.
1534 * Implemented the KICK command into server and client.
1536 * Added `query' argument to the silc_idlist_get_client function
1537 to indicate whether to query the client from server or not if
1540 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1541 to indicate that the client is not channel founder.
1545 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Removed the rng context from SilcPacketContext structure and
1548 changed that the packet routine uses the Global RNG API.
1550 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Added support for quit message that client can "leave" on the
1553 channel when it quits the SILC. It is ditributed inside the
1554 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1556 Added silc_server_free_client_data that will take the
1557 signoff message as argument.
1559 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1561 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Updated parts of the protocol specification to keep it up
1566 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1569 payloads in one packet.
1571 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1572 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1573 use now the new List flag.
1575 * Also deprecated the following packet types: REPLACE_ID,
1576 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1578 * Added list support for Notify packet in server.
1580 * Added silc_server_send_notify_channel_change to send the
1581 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1582 the silc_server_send_replace_id.
1584 * Added silc_server_send_notify_nick_change to send the
1585 NICK_CHANGE notify type. Deprecates the function
1586 silc_server_send_replace_id.
1588 * Added silc_server_send_notify_join to send the JOIN notify type.
1589 Deprecates the function silc_server_send_new_channel_user.
1591 * Added silc_server_send_notify_leave to send LEAVE notify type.
1592 Deprecates the function silc_server_send_remove_channel_user.
1594 * Added silc_server_send_notify_cmode and
1595 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1596 types. Deprecates the silc_server_send_set_mode function.
1598 * Added SERVER_SIGNOFF notify type to indicate that server has
1599 quit. This means that all clients on the channel from that
1600 server will drop. This can be also used when netsplit happens.
1602 Deprecated REMOVE_ID packet type since it is not needed anymore
1605 Added silc_server_send_notify_server_signoff to send the
1606 SERVER_SIGNOFF notify type. Deprecates the function
1607 silc_server_send_remove_id.
1609 Added also silc_server_send_notify_signoff to send the
1610 SIGNOFF notify type.
1612 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1613 SILC protocol from this day on. Changed the protocol
1614 specification as well.
1616 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1617 notify type. It is used between routers to notify about
1618 topic changes on a channel.
1620 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1623 * Partly updated the protocol specification to comply with the
1624 changes now made. It is still though a bit outdated.
1626 * The JOIN notify type now takes one extra argument <Channel ID>.
1627 The packet used to be destined to the channel but now the
1628 JOIN type may be sent as list thus it is impossible to
1629 destine it to any specific channel. By adding this argument
1630 it is again possible.
1632 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Added CREDITS file. The CHANGES and CREDITS file will appear
1635 in the distribution as well.
1637 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1640 types in the server's silcd/packet_receive.c.
1642 * Implemented CMODE and CUMODE to work in router environment.
1644 * Fixed minor encoding and decoding buglet from the
1645 lib/silccore/silcmode.c.
1647 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1650 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1652 * Changed all SilcConfigServer* and silc_config_server* to
1653 SilcServerConfig* and silc_server_config*, respectively.
1656 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1658 * Associated the ID (client or server ID) to the Authentication
1659 Payload to avoid any possibility of forging. Updated the
1660 protocol specification and the code accordingly.
1662 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * The RSA key length is now save to the RsaKey context in the
1665 key generation process in lib/silccrypt/rsa.c. The key length
1666 is now used to figure out the maximum size of the block allowed
1667 to be encrypted/signed.
1669 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1670 is equivalent to the silc_mp_mp2bin but does not allocate any
1673 * Changed silc_mp_mp2bin API to take length argument. If it is
1674 non-zero then the buffer is allocated that large. If zero, then
1675 the size is approximated using silc_mp_sizeinbase, which however
1678 * Created Global RNG API which is global RNG that application can
1679 initialize. After initializing, any routine anywhere in the
1680 code (including library) can use RNG without allocating a new
1681 RNG object. This was done to allow this sort of use of the
1682 RNG in code that has no chance to allocate RNG object. All
1683 applications currently allocate this and many routines in the
1684 library use this. Affected file lib/silccrypt/silcrng.[ch].
1686 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1687 it to use the Global RNG API.
1689 * Defined Authentication Payload into protocol specification that
1690 is used during SILC session to authenticate entities. It is
1691 used for example by client to authenticate itself to the server
1692 to obtain server operator privileges.
1694 Implemented this payload into the lib/silccore/silcauth.[ch].
1695 Implemented also routines for public key based authentication
1696 as the new protocol specification dictates.
1698 Moved definitions of different authentication methods from
1699 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1701 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1702 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1703 silc_pkcs_verify_with_hash functions into the file
1704 lib/silccrypt/silcpkcs.[ch].
1706 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * The client entry's userinfo pointer must be always valid.
1709 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1710 will fail since it requires the userinfo. Now, the userinfo
1711 is allocated as "" if actual userinfo does not exist. Actually,
1712 it must exist and it is totally Ok to drop client connections
1713 that does not announce the userinfo. However, we will make
1714 this workaround for now.
1716 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1717 to return the remote port by socket.
1719 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1722 SILC_SERVER_PENDING_EXEC and added an new macro
1723 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1724 data or when error occurs while processing the pending command.
1726 Added new argument `destructor' into silc_server_command_pending
1727 and to the SilcServerCommandPending object. This destructor is
1728 now called after calling the pending callback or if error occurs
1729 immediately. If error occurs the actual pending callback won't
1730 be called at all - only the destructor. The destructor may be
1731 NULL if destructor is not needed.
1733 All this applies for client library code as well. Similar
1734 changes were made there as well for the pending commands.
1736 In the client, the application must now allocate the
1737 SilcClientCommandContext with the silc_client_command_alloc
1740 * Added reference counter to the SilcServerCommandContext. Added
1741 function silc_server_command_alloc and silc_server_command_dup
1744 Same type of functions added to the client library for the same
1747 * Removed the cmd_ident from IDListData away since it is now
1748 global for all connections. It is the command identifier used
1749 in command sending and with pending commands. The affected file
1752 * Added reference counter to the SilcSocketConnection objecet to
1753 indicate the usage count of the object. The object won't be
1754 freed untill the reference counter hits zero. Currently only
1755 server uses this, and client ignores it. The client must be
1756 set to use this too later. The affected files are
1757 lib/silccore/silcsockconn.[ch]. Added also the function
1758 silc_socket_dup to increase the reference counter.
1760 This was mainly added because it is possible that the socket
1761 is removed underneath of pending command or other async
1762 operation. Now it won't be free'd and proper DISCONNECTING
1763 flags, etc. can be set to avoid sending data to connection that
1764 is not valid anymore.
1766 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1767 the connection. After that it sets SILC_SET_DISCONNECTED.
1768 It is, however, possible that the socket data is not still freed.
1769 The silc_server_packet_process now checks that data is not
1770 read or written to connection that is DISCONNECTED. The socket
1771 get's freed when the reference counter hits zero.
1773 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Changed the client operation API: channel_message operation's
1776 `sender' is now the client entry of the sender, not the nickname
1777 and the `channel' is the channel entry, not the channel name.
1779 In the private_message operation the `sender' is now also the
1780 client entry of the sender not the nickname.
1782 Affected file is lib/silcclient/ops.h and all applications
1783 using the client operations.
1785 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Moved the calling of ops->connect() from connect_to_server_final
1788 into receive_new_id functin since that is the point when the
1789 client is actually allowed to send traffic to network. The
1790 affected file is lib/silcclient/client.c.
1792 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1795 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1796 (if needs broadcasting) instead of broadcasting the packets one
1797 by one which would make a burst in the network traffic.
1799 * Added `broadcast' argument to the functions in silcd/server.[ch]
1800 silc_server_create_new_channel[_with_id] to indicate whether
1801 to send New Channel packet to primary router.
1803 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Added new function into the silcd/server.[ch] files:
1806 silc_server_create_new_channel_with_id to create new channel with
1807 already existing Channel ID.
1809 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1810 lib/silccore/silcpacket.h. This packet is used t send list of
1811 Set Mode payloads inside one packet. Server uses this to set
1812 the modes for the channels and clients on those channels, that it
1813 announced to the router when it connected to it. The protocol
1814 specification has been updated accordingly.
1816 * The silc_server_new_channel did not handle the packet coming
1817 from normal server as it normally does not send that. However,
1818 when it announces its channels it does send it. Implemented
1819 the support for that.
1821 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1822 into the file lib/silccore/id.h.
1824 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1826 * Fixed memory leaks in the functions silc_idlist_del_client,
1827 silc_idlist_del_channel and silc_idlist_del_server in the file
1828 silcd/idlist.c. All of those leaked like a sieve.
1830 * Fixed some small memory leaks in the client's function
1831 silc_client_notify_by_server.
1833 * Added functions into silcd/server.c: silc_server_announce_clients,
1834 silc_server_announce_channels and silc_server_announce_server.
1835 These functions are used by normal and router server to announce
1836 to its primary router about clients, channels and servers (when
1837 router) that we own. This is done after we've connected to the
1840 These functions effectively implements the following packet types:
1841 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1842 and SILC_PACKET_NEW_ID_LIST.
1844 * Added new functions into the silcd/packet_receive.[ch]:
1845 silc_server_new_id_list, silc_server_new_channel_list and
1846 silc_server_new_channel_user_list to handle the incoming
1847 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1849 * Added support of changing Channel ID in the function
1850 silc_server_replace_id. If the server that announces a channel
1851 to the router already exists in the router (with same name but
1852 with different Channel ID), router is responsible to send
1853 Replace ID packet to the server and force the server to change
1854 the Channel ID to the one router has.
1856 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1857 client that the Channel ID has been changed by the router. The
1858 normal server sends this to the client. Client must start using
1859 the new Channel ID as the channel's ID.
1861 Implemented handling of this new type into lib/silcclient/client.c
1862 into the function silc_client_notify_by_server.
1864 * Added new function silc_idlist_replace_channel_id into the files
1865 silcd/idlist.[ch] to replace the Channel ID.
1867 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Call silc_server_command_identify_check always when processing
1870 the IDENTIFY command in silcd/command.c
1872 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1875 send keepalive packets. The packet can be sent by clients,
1876 servers and routers.
1878 Added function silc_socket_set_heartbeat into the file
1879 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1880 If not set, the heartbeat is not performed. The actual
1881 heartbeat is implemented in the low level socket connection
1882 library. However, application is responsible of actually
1885 Added silc_server_send_heartbeat to send the actual heartbeat
1886 packet into silcd/packet_send.[ch]. Server now performs
1887 keepalive with all connections.
1889 * Added silc_task_get_first function into lib/silcutil/silctask.c
1890 to return the timeout task with shortest timeout. There was a bug
1891 in task unregistration that caused problems. TODO has been
1892 updated to include that task system must be rewritten.
1894 * The client library will now resolve the client information when
1895 receiving JOIN notify from server for client that we know but
1896 have incomplete information.
1898 * Rewrote parts of silc_server_remove_from_channels and
1899 silc_server_remove_from_one_channel as they did not remove the
1900 channel in some circumstances even though they should've.
1902 * Encryption problem encountered in server:
1904 The LEAVE command used to send the Channel Key packet to the
1905 router immediately after generating it. However, the code
1906 had earlier sent Remove Channel user packet but not immediately,
1907 ie. it was put to queue. The order of packets in the router
1908 was that Channel Key packet was first and Remove Channel User
1909 packet was second, even though they were encrypted in the
1910 reverse order. For this reason, MAC check failed. Now, this
1911 is fixed by not sending the Channel Key packet immediately but
1912 putting it to queue. However, this is more fundamental problem:
1913 packets that are in queue should actually not be encrypted
1914 because packets that are sent immediately gets encrypted
1915 actually with wrong IV (and thus MAC check fails). So, packets
1916 that are in queue should be encrypted when they are sent to
1917 the wire and not when they put to the queue.
1919 However, the problem is that the current system has not been
1920 designed to work that way. Instead, the packet is encrypted
1921 as soon as possible and left to the queue. The queue is then
1922 just purged into wire. There won't be any fixes for this
1923 any time soon. So, the current semantic for packet sending
1926 o If you send packet to remote host and do not force the send
1927 (the packet will be in queue) then all subsequent packets to the
1928 same remote host must also be put to the queue. Only after the
1929 queue has been purged is it safe again to force the packet
1932 o If you send all packets immediately then it safe to send
1933 any of subsequent packets through the queue, however, after
1934 the first packet is put to queue then any subsequent packets
1935 must also be put to the queue.
1937 Follow these rules and everything works fine.
1939 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Added new function silc_server_remove_clients_by_server to
1942 remove all client entries from ID list when the server connection
1943 is lost. In this case it is also important to invalidate all
1944 client entires as they hold the invalid server entry. This
1945 fixes fatal bug when server has lost connection and will reconnect
1948 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Made some sanity checks to silc_server_daemonise like to check
1951 whether the requested user and group actually exists.
1953 * Added sanity check to SKE's silc_ske_responder_finish to check
1954 that the public and private key actually is valid.
1956 * Invalidate the client's nickname when receiving Replace ID
1957 packet and the Client ID is being replaced. This means that the
1958 server will query the nickname if someone needs it (client)
1961 * Sort the ID Cache in client library when the ID Cache data
1962 has changed (needs sorting).
1964 * Do not allow for SILC client to create several connections to
1965 several servers. The client does not support windows right now
1966 and generating multiple connections causes weird behaviour.
1968 Irssi-silc client does support windows and can handle several
1969 connections without problems, see: www.irssi.org and SILC plugin.
1971 * Fixed some places where client was added to the IDList. The
1972 rule of thumb is following (in order to get everything right):
1973 If the client is directly connected local client then the
1974 `connection' argument must be set and `router' argument must be
1975 NULL to silc_idlist_add_client function. If the client is not
1976 directly connected client then the `router' argument must
1977 bet set and the `connection' argument must be NULL to the
1978 silc_idlist_add_client function.
1980 * The funtion silc_server_packet_send_local_channel actually did
1981 not check whether the client was locally connected or not. It
1982 does that now. Fixed a bug related to LEAVE command.
1984 * Fixed Remove Channel User payload parsing bug in server's
1985 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1987 * The server's silc_server_save_channel_key now checks also the
1988 global ID list for the channel as it might not be in the local
1989 list. Fixed a bug related to LEAVE command.
1991 * Is this the end of the [<unknown>] buglet that has been lurking
1992 around for a long time? A little for loop fix in server's
1993 silc_server_command_whois_parse that is used by both IDENTIFY
1994 and WHOIS command. At least, this was a clear bug and a cause
1995 of one type of [<unknown>] buglet.
1997 * WHOIS and IDENTIFY commands call the function
1998 silc_server_command_[whois/identify]_check function even if
1999 we are not router server.
2001 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Added --with-gmp configuration option. If set the GMP
2004 is always compiled in the SILC source tree. If not set then
2005 it is checked whether the system has the GMP3 installed. If
2006 it has then the GMP won't be compiled (the system's headers
2007 and library is used), if it doesn't have it then the GMP is
2008 compiled in the SILC source tree.
2010 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * Changed RSA private exponent generation to what PKCS #1
2013 suggests. We try to find the smallest possible d by doing
2014 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2015 not security fix but optimization.
2017 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Added new config entry [Identity] to fork the server and run
2020 it as specific user and group. A patch from Bostik.
2022 * Imported Dotconf configuration library into lib/dotconf.
2023 This will be used to create the SILC configuration files later.
2024 It will appear in the distsribution after this commit.
2026 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * A big code auditing weekend happening. Auditing code for
2029 obvious mistakes, bugs and errors. Also, removing any code
2032 Removed files for being obsolete:
2034 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2035 inline in the file lib/silcutil/silcbuffer.h)
2037 o lib/silcutil/silcbufutil.c (the header has inline versions)
2039 Changed code to fix possible error conditions:
2041 o The buffer formatting routines now check that the destination
2042 buffer really has enough space to add the data. This applies for
2043 both buffer formatting and unformatting
2044 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2045 unformatting was changed to accomodate following rules:
2046 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2047 sent to the function while XXX_*STRING will not allocate or copy
2048 the data into the buffer. Instead it sets the pointer from the
2049 buffer into the pointer sent as argument (XXX_*STRING used to
2050 require that the pointer must be allocated already). This change
2051 makes this whole thing a bit more consistent and more optimized
2052 (note that the data returned in the unformatting with XXX_*STRING
2053 must not be freed now). The routines return now -1 on error.
2055 o Tried to find all code that use buffer_format and buffer_unformat
2056 and added return value checking to prevent formatting and
2057 especially unformatting errors and possible subsequent fatal
2060 o Changed ske->x and ske->KEY to mallocated pointers in
2061 lib/silcske/silcske.h. Fixed possible data and memory leak.
2063 o Added return value checking to all *_parse* functions. Fixed
2064 many memory leaks as well.
2066 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2067 so that buffer overflows would not happen. All code now also
2068 checks the return value as it can fail.
2070 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Added reconnection support to server if the normal server looses
2073 its connection to the router (for example if router is rebooted).
2074 The server performs normal reconnection strategy implemented
2075 to the server. Affected file silcd/server.c.
2077 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Added new packet type SILC_PACKET_SET_MODE that is used to
2080 distribute the information about changed modes (for clients,
2081 channels and clients channel modes) to all routers in the
2082 network. Updated the protocol specification accordingly.
2084 Added functions into silcd/packet_send.c and
2085 silcd/packet_receive.c: silc_server_send_set_mode,
2086 silc_server_set_mode.
2088 Added new files silcmode.[ch] into lib/silccore that implements
2089 the encoding and decoding of Set Mode Payload. Added new type
2090 SilcSetModePayload. Moved the definitions of different modes
2091 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2093 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Oops, a little mistake in server's connection authentication
2096 protocol. The protocol is not ended with FAILURE but with
2097 SUCCESS if the authentication is Ok. :) Affected file is
2100 * Implemented NICK_CHANGE notify handling in server in the file
2101 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2102 the local clients on the channel. After the changing nickname
2103 in router environment snhould work and the [<unknown>] nickname
2104 should appear no more.
2106 The silc_server_replace_id function that receives the Replace ID
2107 payload now sends the NICK_CHANGE notify type also in the file
2108 silcd/packet_receive.c
2110 * Changed WHOIS and IDENTIFY command to support the maximum amount
2111 of arguments defined in protocol specs (3328 arguments). This
2112 fixed a bug that caused problems when there were more than three
2115 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Added extra parameter, command identifier, to the
2118 silc_client_send_command so that explicit command identifier
2121 Changed that ID list routines uses specific command identifier
2122 when sending WHOIS/IDENTIFY requests to the server so that they
2123 can be identified when the reply comes back.
2125 Affected files lib/silcclient/command.[ch],
2126 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2128 * Added `sender' argument to silc_server_packet_send_to_channel
2129 to indicaet the sender who originally sent the packet to us
2130 that we are now re-sending. Ignored if NULL. Affected file
2131 silcd/packet_send.[ch].
2133 * Added some server statistics support in silcd/server_internal.h
2134 SilcServerStatistics structure and around the server code. Also
2135 send some nice statistics information when client is connecting
2138 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Fixed channel ID decoding in server's JOIN command reply in
2141 silcd/command_reply.c
2143 * Fixed braodcasting of replace ID payload to not to send it if
2144 we are standalone server in silcd/packet_receive.c.
2146 * Fixed all channel message sending routines to not to send
2147 packets to clients that has router set, since they are routed
2148 separately in the same function earlier. Affects file
2149 silcd/packet_send.c and all channel packet sending functions.
2151 * In USERS reply, res_argv[i] are not allocated, the table
2152 is allocated. Thus changed that free the table, not its
2155 * In server's whois_check and identify_check if the client is
2156 locally connected do not send any WHOIS commands - they are not
2159 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Fixed some minor bugs in client when sending WHOIS command. The
2162 arguments was in wrong order.
2164 * Removed statis function add_to_channel from server in
2165 silcd/command.c that was previously used with the joining but
2168 * Tested USERS command in router environment successfully with two
2169 routers, two servers and two clients.
2171 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2173 * Reorganized the USERS command and command reply in client library
2174 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2175 When the command is given by user we register a pending command
2176 callback that will reprocess the command after the reply has been
2177 received from the server. When reprocessing the packet we then
2178 display the information. Thus, the USERS information is displayed
2179 now in the command callback instead of in the command reply
2180 callback. The processing of the command is same as previously
2181 when server has sent the command reply in the JOINing process.
2183 * Added to USERS command in silcd/command_reply.c to join the client,
2184 we didn't use to know about, to the channel after we've created
2185 a client entry for it. Also, for clienet we did know already still
2186 check whether it is on the channel or not and add it if not.
2188 * Removed silc_server_command_join_notify as the function and its
2191 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Changed the client's pending command handling to the same as the
2194 server's pending command handling. It is also now possible to
2195 execute command reply functions from other command reply
2196 function as the function callbacks for commands and command
2197 replies are one and same. The pending commands are not static
2198 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2199 in client connection context. Thus, pending commands are server
2200 connection specific as it is convenient.
2202 Changed the function silc_client_command_pending and
2203 silc_client_command_pending_del and added new function
2204 silc_client_command_pending_check. Removed the
2205 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2208 * Added cmd_ident, current command identifier, to the client
2209 connection context in lib/silcclient/client.h to keep track on
2210 command identifiers used in command sending. Client's command reply
2211 function handling now supports the mandatory command identifiers.
2213 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2214 funtions in client to fully support pending command callbacks.
2216 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2217 as one of the arguments to the application in the command reply
2220 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2221 before first releasing SILC but came back. Now it is removed again
2222 and should come back nomore. The FORWARDED flag was used only
2223 by the JOINing procedure by forwarding the command packet to router.
2224 Now, the JOINing procedure has been changed to more generic (due
2225 to various router environment issues) and FORWARDED is not needed
2226 anymore for anything. The protocol specification is yet to be
2229 Now, removed silc_server_packet_forward from server and the flag
2230 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2232 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Renamed NAMES command to USERS command. The NAMES was named that
2235 due to historical reasons. Now it is renamed. Also, rewrote
2236 parts of the USERS command. The nickname list is not sent anymore
2237 by the server. Only Client ID and mode lists are sent in the USERS
2238 command. Changed this also to the protocol specification.
2240 The client now resolves the names and stuff after it receives
2241 the USERS list from the server when joining to the channel.
2243 * WHOIS and IDENTIFY commands has been changed to support multiple
2244 Client ID's per command. One can now search for multiple users
2245 in the network by sending only one WHOIS or IDENTIFY command.
2246 Changed the code and the protocol specifications.
2248 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2249 uses silc_server_command_whois_parse to parse the request. */
2251 * If normal server, do not parse the WHOIS and IDENTIFY requests
2252 before sending it to the router. Saves some time.
2254 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Fixed JOIN command on client library. Wrong number of arguments
2257 used to crash the client.
2259 * Added silc_server_channel_has_global function to check whether
2260 channel has global users or not.
2262 * Added silc_server_channel_has_local function to check whether channel
2263 has locally connected clients on the channel.
2265 * The silc_server_remove_from_one_channel now checks whether the
2266 channel has global users or not after given client was removed from
2267 the channel. It also checks whether the channel has local clients
2268 on the channel anymore. If it does not have then the channel entry
2269 is removed as it is not needed anymore.
2271 * The silc_server_notify now checks on JOIN notify whether the joining
2272 client is one of locally connected or global. If it is global then
2273 the channel has now global users on the channel and that is marked
2274 to the channel entry. Also, it now saves the global client to
2275 global list who is joining and JOINs it to the channel. This is
2276 for normal server, that is.
2278 Changed silc_server_send_notify_on_channel,
2279 silc_server_packet_relay_to_channel and
2280 silc_server_packet_send_to_channel check if we are normal server
2281 and client has router set (ie. global client) do not send the
2282 message to that client, as it is already routed to our router.
2284 * Implemented LEAVE notify type handling in silc_server_notify
2287 * Tested LEAVE command in router environment successfully. Tested
2288 with two routers, two servers and two clients.
2292 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2294 * Implemented SIGNOFF notify type handling in silc_server_notify
2297 * silc_server_remove_id now removes the client entry from all channels
2298 it has joined and thusly sends SIGNOFF notify type.
2300 * Rewrote the NAMES list generation in server by removing two excess
2301 loops. The lists are created now inside one loop.
2303 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * silc_server_remove_channel_user checks now also global list
2306 for channel and client.
2308 * silc_server_new_channel_user checks now both local and global
2309 list for channel and client. Fixed a bug in client id decoding.
2310 Used to decode wrong buffer.
2312 * silc_server_channel_message checks now both local and global
2313 list for channel entry.
2315 * Tested channel joining (hence JOIN) in router environment
2316 successfully. Tested with two routers, two servers and two
2319 * Tested channel message sending in router environment successfully.
2321 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Added silc_server_save_channel_key into server.[ch] to save the
2324 received channel key in Channel Key payload processing. It is
2325 also used in JOIN command reply handling.
2327 Equivalent function silc_client_save_channel_key added into
2328 client.[ch] into client library.
2330 * Changed JOIN command reply to send information whether the channel
2331 was created or not (is existing already) and the channel key
2332 payload. Changed protocol specs accordingly.
2334 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2335 the request was sent by ID and not by nickname. Crashed on
2338 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2341 now correctly save the received data.
2343 * silc_server_free_sock_user_data now notifies routers in the
2344 network about entities leaving the network.
2346 At the same time implemented functions silc_server_remove_id
2347 and silc_server_send_remove_id to receive and send REMOVE_ID
2348 packets. The packet is used to notify routers in the network
2349 about leaving entities. The ID removed will become invalid in
2352 * Added function silc_idlist_del_server into server. Removes and
2353 free's server entry from ID list.
2355 * silc_server_private_message function now checks, if we are router,
2356 that the destination ID really is valid ID, naturally.
2358 * In router when NEW_ID packet is received (for new client) the
2359 hash of the Client ID is saved in the ID Cache but the
2360 client->nickname is set to NULL, instead of putting the hash
2363 IDENTIFY command now also checks that client->nickname must be
2364 valid. If it is not if will request the data from the server who
2365 owns the client. Added new function
2366 silc_server_command_identify_check.
2368 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2369 to set the command to already allocated Command Payload.
2371 * Tested private message sending in router environment with two
2372 routers, two servers and two clients. Fixed minor bugs and now
2375 * Fixed segfault from client's NAMES command. Used to crash if
2378 * Forwarded packets must not be routed even if it is not destined
2379 to the receiver. Changed server code comply with this.
2381 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Added `require_reverse_mapping' boolean value to ServerParams
2384 structure. If TRUE (not default) the server will require that
2385 the connecting host has fully qualified domain name.
2387 If the reverse mapping is not required and hostname could not be
2388 found the IP address is used as hostname.
2390 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Implemented version string checking to both client and server.
2393 The check is incomplete currently due to the abnormal version
2394 strings used in development version of SILC.
2396 * Changed all command functions in server to use the new
2399 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Changed char *data to unsigned char *data in ID Cache system to
2402 support binary data as ID Cache data. Changed code to support
2403 binary data in lib/silccore/idcache.c.
2405 * Renamed silc_server_packet_relay_command_reply to
2406 silc_server_command_reply as it is normal packet receiving
2407 function. Rewrote the function to accept command replys for
2408 servers and not only for clients.
2410 * Mark remote router always as registered server if we are connecting
2411 to it. Otherwise, commands sent by the router to us are ignored.
2413 * All ID List find routines now returns the ID Cache Entry pointer
2414 as well if requested.
2416 * WHOIS command works now in router environment, tested with two
2417 routers, two servers and two clients.
2419 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2420 in router environment (as it is almost equivalent to WHOIS) but
2421 hasn't been tested thoroughly. Added new functions:
2423 silc_server_command_identify_parse
2424 silc_server_command_identify_send_reply
2425 silc_server_command_identify_from_client
2426 silc_server_command_identify_from_server
2428 * Disabled route cache adding because adding two different ID's with
2429 same IP replaces the old cache entry thus giving wrong route.
2430 The entry->router->connection is always the fastest route anyway
2431 so route cache may not be needed. Of course, new routes maybe
2432 established after receiving the ID when the entry->router->connection
2433 might not be anymore the most optimal.
2435 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Add route cache for received ID for fast routing.
2439 * Added silc_server_packet_route to route received packet on router
2440 that is not destined to us.
2442 * Renamed silc_server_get_route to silc_server_route_get.
2444 * Added id_string and id_string_len fields into SilcServer to
2445 include encoded ServerID for fast comparing without excess
2446 encoding of the ID's.
2448 * Cleaned up WHOIS command on server side. Added following static
2451 silc_server_command_whois_parse
2452 silc_server_command_whois_check
2453 silc_server_command_whois_send_reply
2454 silc_server_command_whois_from_client
2455 silc_server_command_whois_from_server
2457 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2458 arguments in command replies. All command functions should be
2459 updated to use this macro.
2461 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Minor typo fixes on command reply handling on server.
2465 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Added silc_server_command_add_to_channel internal routine to add
2468 the client to the channel after router has created the channel and
2469 sent command reply to the server.
2471 * Added generic silc_server_send_command to send any command from
2474 * Use static buffer with ID rendering instead of duplicating data.
2476 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Fixed a channel user mode bug when joining to a channel server gave
2479 everybody channel founder rights, oops.
2481 * We mark ourselves as the router of the incoming server connection
2482 if we are router ourselves. This way we can check in some packet
2483 sending functions whether it is locally connected server. For
2484 incoming router connections we put NULL.
2486 * For router sending packets locally means now always sending the
2487 packet cell wide; to local clients and local servers. For normal
2488 server sending packet locally means sending it to only local
2491 * Fixed the JOIN command to really work in router environment. If the
2492 channel is created it is always created by the router. Router is
2493 also responsible of making the initial joining to the channel,
2494 sending JOIN notify to the sending server and distributing
2495 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2496 does not exist server doesn't do anything else but forward the
2497 command to the router which performs everything.
2499 * Added silc_server_send_channel_key function to send the Channel Key
2502 * Added silc_server_create_channel_key to create new channel key. The
2503 channel key is now re-generated everytime someone joins or leaves
2504 a channel, as protocol dictates. Note: channel->key_len is the
2507 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2510 packet_receive.[ch] to separate packet sending and receiving
2511 routines. The server.[ch] now includes everything else including
2512 actual packet processing (writing and reading data) and other
2515 Renamed silc_server_private_message_send_internal to
2516 silc_server_send_private_message. The routine is still though
2517 used only to relay private messages as server does not send
2518 private messages itself.
2520 Renamed silc_server_new_channel to silc_server_create_new_channel
2521 and added new function sicl_server_new_channel that handles the
2522 incoming New Channel packet. Added also new sending function
2523 silc_server_send_new_channel to send New Channel Payload.
2525 * Added new function silc_server_notify to process incoming notify
2526 packet to the server/router. Server may then relay the notify
2527 to clients if needed.
2529 * Added new function silc_server_new_channel_user to process incoming
2530 New Channel User packet. Router will redistribute the packet and
2531 send JOIN notify to its local clients and locally connected servers
2532 if needed. Normal server will send JOIN notify to its local client
2533 on same channel when received this packet. Added also corresponding
2534 sending function silc_server_send_new_channel_user to sent the
2537 * Added boolean route argument to send_notif_to_channel and
2538 packet_send_to_channel functions to attempt to route the packet
2539 if it is TRUE and send only locally if it is FALSE.
2541 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * silc_server_replace_id now broadcasts the received replace ID
2544 packet if it is not broadcast packet already. The router must
2545 broadcast to inform other routers about changed ID.
2547 * Added backpointer to server's router into SilcServer context in
2548 silcd/server_internal.h.
2550 * Fixed silc_server_packet_broadcast to send correct broadcast
2553 * The channel key is now distributed to the local client as soon
2554 as it is received from the router (in router environment) so that
2555 no other packet may be sent for the channel until client has
2558 * silc_server_remove_channel_user now broadcasts the received
2559 Remove Channel User packet if it is not broadcast packet already.
2560 The router must broadcast to inform other routers about removed
2563 * Added users field into SilcPacketContext that is a reference count
2564 of the context. One can increase the reference count by calling
2565 silc_packet_context_dup which is now changed to just increase the
2566 reference count instead of duplicating the data. The reference
2567 count is decresed by calling silc_packet_context_free that will
2568 free the data after the reference count hits zero.
2570 For now on the packet context and everything allocated into it
2571 (including the raw packet from network) must be freed by calling
2572 the new silc_packet_context_free function. Added also new function
2573 silc_packet_context_alloc that must be used now to allocate the
2574 context. This also means that if a routine is asynchronous from
2575 silc_[client/server]_packet_parse_type the packet context must
2576 be duplicated by calling silc_packet_context_dup. Otherwise it
2577 gets free'd after silc_[client/server]_packet_parse_type returns.
2578 Also, one must remember that if packet is duplicated then its
2579 reference count must be decresed by calling the free function as
2580 many times as it was duplicated.
2582 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2583 from both client and server.
2585 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Made joining to a channel working in router environment.
2589 * Cleaned up JOIN command on server side and create function
2590 silc_server_command_join_channel internal routine to make the
2593 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Changed silc_command_pending list to SilcDList. Also, added
2596 `ident' field to SilcServerCommandPending structure to identify
2597 the reply and to call correct callback.
2599 Added silc_server_command_pending_check function to replace the
2600 corresnponding macro. The silc_command_pending list is not
2603 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2604 to set identifier to previously allocated Command Payload. It
2605 is used to set identifier for command when resending Command
2608 * Added silc_command_payload_encode_payload to encode Command
2609 Payload buffer from SilcCommandPayload structure.
2611 * Added silc_argument_payload_encode_payload to encode Argument
2612 payload buffer from SilcArgumentPayload structure.
2614 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Changed WHOIS command to support router connection on server side.
2617 The whois request is always sent to router unless the server is
2618 standalone server. After server has received the reply from the
2619 router will it send the reply to the client.
2621 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2622 broadcast received broadcast packet. The function is used only
2623 by router. The broadcast packet is always sent to the router's
2626 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2627 render given ID to printable string, for log files for example.
2629 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Made basic router to router connections working. At least they
2632 can now connect to each other but nothing really works the way
2633 they are supposed - yet.
2635 * Added new initiator token to RouterConnection configuration
2636 file in silcd/serverconfig.[ch]. It is used to tell whether we
2637 are the initiator to the remote router or whether we'll expect
2638 the other end to connect.
2640 * Moved registering of listener task to silc_server_init, hence
2641 the server starts listenning as soon as it is run, even if it
2642 does not have connections to other routers. Let's see how well
2645 * Changed default connection retry timeouts for more suitable in
2648 * Removed cipher and such arguments from silc_idlist_add_client
2649 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2650 Added new function silc_idlist_add_data to add the keys and stuff
2653 * Added SilcIDListData structure and added it to SilcClientEntry
2654 and SilcServerEntry as their first field in the structure. This
2655 way we can explicitly cast the ID entries to the SilcIDListData
2656 structure and get common data for the entries. In past, we had
2657 to first check what type of connection it is and then cast it to
2658 correct ID entry type. Now, we can directly cast the opaque
2659 pointer to the SilcIDListData (no matter what ID entry it actually
2660 is) and get the data needed.
2662 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2665 in some circumstances even if threre were timeout tasks, though not
2666 IO tasks, but tasks anyway. Now fixed.
2668 * Defined SilcServerConnection structure to hold connection specific
2669 stuff about directly connected servers and routers. The definition
2670 is currently in silcd/server_internal.h. I thought about having
2671 a bit more important role fro this struct but for now it is used
2672 only when connecting to other server (or router actually).
2674 * Added connecting retry support in server when connecting to
2675 router(s). The retry feature implement exponential backoff
2676 algorithm. Also, added SilcServerParams structure to hold default
2677 parameters for server. For now, it include these retry settings
2678 and are hard coded. After server is moded to be as Silc Server
2679 Library this structure will be more important.
2681 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Changed client librarys channel->clients table to SilcList and
2684 changed code accordingly.
2686 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Changed client's channel table to SilcList and changed code
2689 accordingly. Also changed SilcChannelClientEntry to include back-
2690 pointer to the channel so that client entry can use that structure
2691 as list as well and we have fast cross-reference to the channel.
2692 This change dramatically decreased the complexity of channel
2693 handling with client entry and vice versa (removed one extra
2694 loop when searching for channel entry from many functions).
2696 * Changed server->sim from table to SilcDList and changed code
2699 * NAMES command can now be used from user interface. It will show
2700 the user list on the channel, neatly.
2702 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2703 Code now saves realname of the user if it becomes available.
2705 * Renamed configure.in to configure.in.pre and made ./prepare
2706 script to automatically add correct version string to
2707 configure.in which it creates from configure.in.pre.
2709 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * NAMES command reply now shows users mode with the nickname when
2714 * Moved silc_client_ch[u]mode[_char] functions from
2715 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2716 place sucks, they are utility functions and should be in some
2719 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2721 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2724 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Added TRQ (efficient deque and list library) into lib/trq. This is
2729 a very good list library that is currently used in the SILC. Defined
2730 SilcList API over the library because I didn't like the API very
2731 much. See lib/trq/silclist.h for the API and examples of how to
2732 use the API. Fixed various places in the code to use the new
2733 SilcList API. The SilcList is meant for lists that has a structure
2734 already defined as a list. It is not suitable to add just some
2735 context to the list (in TRQ, the context is the list actually).
2737 So, I defined SilcDList that can be used for the purpose where
2738 predefined list structure does not exit. This can be used as
2739 such list. Now some context just can be added to the SilcDList.
2740 Currently this list is not used in the SILC just yet, though there
2741 are a lot places where this can replace dynamically allocated
2742 tables and I will fix these places, later, to use SilcDList.
2743 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2744 and use TRQ internally).
2746 Also fixed some annoying warning messages that the original TRQ
2747 code generated. Also minor changes to TRQ's Makefile.in.
2749 * Added support for querying by Client ID to both WHOIS and
2750 IDENTIFY commands into server, as required by the protocol.
2752 * Removed method function pointers from SilcBuffer structure. They
2753 weren't used to anything and just increased the context size for
2754 no good reason. This change also made silc_buffer_alloc and
2755 silc_buffer_free functions inline functions.
2757 * Disabled command flooding detection support until it's fixed so
2758 that it accepts commands in but does not execute them more than once
2761 * Added silc_net_localhost(), to return local hostname, into
2762 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2763 that must be initialized before calling silc_client_init.
2765 * Added new function: silc_server_send_notify_on_channels to send
2766 notify messages to all channels client has joined. It is assured
2767 that the message is sent only once per client.
2769 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2770 lib/silcutil/silcutil.[ch] as silc_format function. The new
2771 function is generic and is used by server as well, not only by
2772 the logging routines.
2774 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2775 the provided version string was not acceptable. Added new function:
2776 silc_ske_check_version into lib/silcske/silcske.h. The function
2777 must be implemented by the application (client or server) and it
2778 does not reside in the SKE library. The function checks the version
2779 string remote end sent.
2781 * Added back pointers (to opaque context and to SilcSocketConnection)
2782 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2784 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2785 duplicate packet context structure.
2787 * Changed `notify' client operation to send same arguments as client
2788 receives from server except for ID's. ID's are mapped to correct
2789 ID entry and that is returned. Also, if channel entry is not sent
2790 by server but the notify is for channel the channel entry is sent
2791 to application (otherwise application doesn't know that it is for
2792 channel (library gets it from packet's Destination ID)).
2794 * Added silc_client_remove_from_channels into client library to
2795 remove a client from all channels it has joined to. Used when
2796 received SIGNOFF notify from server. Added also new function
2797 silc_client_replace_from_channels to replace old ID entry with
2798 new ID entry on all channels. Used when received NICK_CHANGE
2801 * Fixed ID Cache list handling in silc_idlist_get_client in
2802 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2803 to get (or query) client by ID.
2805 * Updated TODO list.
2807 * Added connection authentication status message defined by the
2808 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2809 support for these into the code in client and server side.
2811 * Added generic function silc_client_send_command to send any command
2812 with variable argument list. Application should use this function
2813 to send commands if the command functions provided by the library
2814 does not suite for the application's user interface needs.
2816 * Added new `failure' client operation. Application is notified about
2817 received failure packet if client is executing a protocol. In this
2818 case the protocol's execution has failed.
2820 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2821 is required by the protocol.
2823 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2824 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2827 * Added status flag to SilcSKE object to indicate realtime status
2828 of the SKE protocol.
2830 * Application receives now exactly same command reply arguments as
2831 the library receives from server. However, if ID is received the
2832 corresponding ID entry is returned to the application (eg. Client
2833 ID is mapped to correct SilcClientEntry entry and that is returned).
2834 Changed command_reply client operation due to this change.
2836 * Changed all ID's in commands and in command replys as ID Payloads.
2837 Change affected both client and server side codes.
2839 All ID's sent in SILC network (with execption of ID's in SILC
2840 Packet header) are sent in ID Payload to support variable length
2843 * Server now notifies nick changes and notifies all clients on
2844 the channels about the new nickname (about the new Client ID,
2847 * Implemented CMODE command to change channel modes. Supports all
2848 channel modes defined by the protocol specs except ban and invite
2849 lists. (Also, private channel key mode is supported but support for
2850 setting private channel key in client is missing, thus, this mode
2851 has no effect on client side (except that server requires that the
2852 client uses private channel key and normal channel traffic does not
2855 Also, invite mode works per se, but INVITE command does not work
2856 yet correctly, so you can set channel as invite only channel but
2857 inviting clients to the channel does not work (it is yet to be
2858 thought what's the best way to do it).
2860 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2861 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2862 Implemented CUMODE command to change user's mode on the channel.
2863 Supports all modes defined by the protocol specs.
2865 * Added NAMES command reply to return users modes on the channel.
2867 * Removed unnecessary and slow ciphers from lib/silccrypt.
2869 * Set SO_KEEPALIVE option to connection sockets by default.
2871 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2873 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2874 redefined the Notify Payload into protocol specs.
2876 * Added silc_id_payload_parse_id to get ID directly from raw
2879 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2882 accept searching by Client ID as well.
2884 * Added support for LEAVE and SIGNOFF notify types in client library.
2886 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2887 to parse ID Payload from raw data.
2889 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Added flags parameter into silc_ske_assemble_security_properties
2892 function in lib/silcske/silcske.[ch].
2894 * Changed notify client operation to fit better for notify messages
2895 sent by server. The notify payload received from server is now
2896 passed to the application (after parsing it to SilcNotifyPayload).
2897 It is application's responsibility to retrieve the arguments
2898 from the payload and show the message the way it wants. The message
2899 sent by server is implementation specific.
2901 * Changed public keys to comply with the protocol specification.
2902 Old public keys are not supported anymore and are not compatible.
2904 * Removed nickname from Channel Payload as the latest draft removed
2905 it. The client must resolve the nickname from the NAMES command
2906 reply received when it joined the channel.
2908 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2910 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Fixed some errors in protocol specification drafts.
2914 * Created lib/silccore/silcnotify.c to implement Notify Payload
2915 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2916 generic payloads described by protocol specifications. The file
2917 includes implementations for ID Payload and Argument Payload.
2919 * Changed Command Payload implementation to use the new Argument
2920 Payload. Changed command_xxxx_payload to command_payload_xxxx
2921 to comply with SILC coding conventions.
2923 * Added suppport for Argument Payload handling in Notify Payload
2924 implementation as protocol requires it. Added the new support
2925 into server and client lib as well.
2927 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Added support for multiple nicknames on same channel. [n] is
2930 added locally to the nickname if there are more than one same
2931 nicknames on the channel.
2933 * Server now sends all nicknames that matched WHOIS request.
2934 Client also shows the list received from server.
2936 * Added TOPIC command to client side. User can now set and show
2937 current topic on channel.
2939 * Added MOTD command to client and server. Also, server sends the
2940 motd when client connects to the server.
2942 * Changed version strings to comply ISO 8601.
2944 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Fixed protocol error handling in client library. It should now
2947 cope even if the SKE fails for some reason.
2949 * Made new protocol specification drafts for submitting to IETF.
2951 * Implemented TOPIC command to server in silcd/command.c.
2953 * Added two new notify types into lib/silccore/silcnotify.h:
2954 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2955 notify nickname change and topic setting/change on a channel.
2957 * API change of command_reply operation in client library. The
2958 application gets now the status type received from server as well.
2960 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2964 * Cras fixed and optimized the packet handling even further and
2965 it should work now. Minor change to the prototype of function
2966 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2968 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Added new function into lib/silcutil/silcschedule.[ch]:
2971 silc_schedule_with_fd to select() a specified fd. The function
2972 returns after timeout expires or data arrives or goes. The
2973 function is used by packet routines to wait that all data is
2974 received from network.
2976 * Fixed data reading from network in lib/silccore/silcpacket.c.
2977 The code now assures that all data is read from the fd and then
2978 continues packet processing. This was a bug fix since the code
2979 used to drop some data in some circumstances.
2981 * Added new function into lib/silcclient/client.[ch]:
2982 silc_client_start_key_exchange to start key exchange after
2983 connection has been established to server. The code internally
2984 now uses this funtion but its main purpose was to provide it
2985 for applications that perform their own connecting. After
2986 application has created a connection it merely calls this
2987 function to start the key exchange between client and server.
2988 The library takes care of everything else after that.
2990 Updated also lib/silcclient/README to explain the usage of
2993 * Do not send to application information that connection has
2994 been established. Application gets notified it by connect
2997 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Applied cras's patch to add silc_schedule_one function. The
3000 function runs scheduler once and returns.
3002 * Fixed the scheduler after cras messed it up. The timeout
3003 handling works now as it's supposed to work.
3005 * Added into lib/silccore/ silcnotify.h to include notify
3006 message types support. Changed silc_server_send_notify*
3007 functions, in server.[ch], to support those new notify types.
3008 Added the support for the notify types into client library,
3009 as well. Added new notify client operation into ops.h in
3012 * Changed silc_server_packet_send_to_channel to send normal
3013 packets instead of just channel message packets. The function
3014 is now used to send the notify packets to channels. It is not
3015 used to send channel message packets anymore, as server never
3018 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3019 va_arg()s as it seems to require it nowadays. I guess, if SILC
3020 is compiled with older va_arg() the new code should work anyway.
3022 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Splitted core library. Core library (lib/silccore) includes
3025 now only SILC protocol specific core (and common) components.
3026 Created new utility library (lib/silcutil) that includes more
3027 generic purpose stuff. The stuff for util library was taken
3028 from the old core library. This was minor and easy split.
3030 * Created SILC Client Library (lib/silcclient) that includes
3031 implementation of the SILC client without user interface. This
3032 was major move from silc/ directory. The code has been changed
3033 so that it is transparent towards the user interface. The
3034 silc/ directory includes now the same user interface as before
3035 and it uses the new client library. Read lib/silcclient/README.
3036 Basicly, the client library performs everything else related
3037 to SILC except user interface handling. Also, configuration
3038 files are considered to be part of user interface and library
3039 does not handle them.
3041 This change also changed a lot of structures, function naming etc.
3042 Most important change was that SilcClientWindow object was
3043 renamed to SilcClientConnection in the client library. Created
3044 also new file lib/silcclient/ops.h. Also added new files
3045 silc/local_command.[ch] and silc/client_ops.[ch].
3047 All these changes were made to make it easier for user interface
3048 designers to create what ever user interface for the SILC client
3051 It is also expected that the server will be moved to lib
3052 directory as well and SILC Server Library will be created;
3053 sometimes in the future.
3055 * Removed Local commands from lib/silccore/silccommand.h as
3056 they are application specific and new client library does not
3057 handle any of those anymore.
3059 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3060 old client implementation in silc/.
3062 * Added support for callback functions in SILC_LOG_* macros.
3063 Application can now set its own callbacks that will be called
3064 instead of using the default functions that will always print
3065 the debug messages to stderr (or stdout). Also, debugging can
3066 now be disabled by setting silc_debug to FALSE and re-enabled by
3067 setting it to TRUE. Note, that logging will still work even
3068 if debugging is disabled.
3070 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3071 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3072 silc_log_reset_debug_callbacks.
3074 * To enable debugging in silc client one must give now -d
3075 option on command line.
3077 * Changed silc_schedule_init to automatically allocate task queues
3078 if they are not allocated before calling it.
3080 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Added GMP 3.1 into math library.
3084 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3087 a channel in SILC network. The packet is used by servers and
3088 routers to notify other routers that user has left a channel.
3089 This little feature was missing until now. Added the feature
3090 to protocol specification as well.
3092 Added functions: silc_server_send_remove_channel_user and
3093 silc_server_remove_channel_user into server.[ch].
3095 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3096 lib/silccore/silcpacket.h. However, they are not implemented
3099 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Fixed joining to a channel and sending channel messages
3102 between server and router. The channel message sending should
3103 now work inside a cell.
3105 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Fixed the private message sending between server and router.
3108 The private message sending should now work inside a cell.
3110 * Added silc_server_replace_id into server.[ch] to replace
3111 existing ID in the SILC network.
3113 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3114 and silc_idlist_replace_server_id into idlist.[ch] in server.
3116 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Fixed the server to server connections. Server can again now
3119 connect to router. Router to router connections probably does
3122 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added dynamic protocol registering support. Now protocols can
3125 registered and unregistered on the fly. Patch by cras.
3127 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Added lib/contrib directory to hold routines that some platforms
3130 don't have but are needed by SILC.
3132 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3133 into lin/contrib to provide getopt() and getopt_long() for
3134 those who don't have it.
3136 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added AWAY command to client. When away message is set and
3139 client receives a private message packet the client automatically
3140 replies to the sender with the away message.
3142 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3143 bug seemed to be the cause of recent problems when compiling
3146 * Added version detection support to SKE protocol specification
3147 and added the new changes to the SKE implementation as well.
3148 There were other minor changes in the SKE protocol as well.
3150 Many changes in lib/silcske/silcske.[ch] and in
3151 lib/silcske/payload.[ch].
3153 * Added ^U functionality, clear input line. Patch from cras.
3155 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Mainly small bugfixes on core library. Fixed some debugging
3158 logging and buffer overflow in silclog.c.
3160 * Updated config.sub and config.guess on the distribution tree.
3162 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Added command lagging support in server. Client may execute
3165 commands now only once in two seconds.
3167 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Optimized packet reception. MAC computation and checking is now
3170 also more optimized. A lot previously duplicated code is now
3171 used as generic by both client and server.
3173 * Fixed key pair generation in clientutil.c
3175 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added into lib/silccore/silcbufutil.[ch] new function;
3178 silc_buffer_realloc.
3180 * Moved generic packet sending/encryption functions to
3181 lib/silccore/silcpacket.[ch] from client and server. Some
3182 rewriting of the functions.
3184 * Moved all generic packet reception/decryption functions to
3185 lib/silccore/silcpacket.[ch] from client and server. The
3186 packet processing is now much cleaner in both client and server.
3187 These were major changes in both client and server.
3189 * Created many common functions in server to do packet sending.
3190 Previously code were duplicated a lot, this has been removed
3193 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Rewrote major parts of the ID cache system. Don't know
3196 whether it is better now or not but at least the API is more
3199 * Major rewrite on ID cache stuff on client because of the ID
3200 cache API changes. Added idlist.c to client.
3202 * Also major rewrite on ID cache stuff on server as well.
3203 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3204 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3205 in hand, instead they are all put into the ID cache system now.
3206 All server_idlist_* routines uses ID cache now instead of
3207 traversing its own lists (those lists does not exist anymore).
3208 SilcIDList though still exists. Also, SilcXXXEntry's are
3211 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Finally made the SKE implementation compliant to the protocol
3214 specification. All mp integers are now binary encoded as
3215 opposed being HEX encoded.
3217 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3220 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3221 functions: silc_[encode/decode]_pem. Also added function
3222 silc_encode_pem_file to PEM encode with newlines ('\n') for
3225 * SILC public keys are now encoded either PEM or binary. Same
3226 option is for private keys as well. By default private keys
3227 are binary encoded and public keys PEM encoded. Silly HEX
3228 encoding were removed.
3230 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3231 function to create fingerprints.
3233 * Fixed a bug in SHA1; does not change the original data anymore.
3235 * Partly implemented INFO command on client and server side.
3236 Fixed CLEAR command. Changes to SERVER command; show current
3237 server(s) when giving command without arguments. Added
3238 VERSION command to client.
3240 * Added check to server that unregistered connections cannot
3241 execute commands (unless it is specificly allowed).
3243 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Fixed screen refresh.
3247 * Fixed channel joining bug from client. On some circumstances
3248 client tried to join to a channel it had already joined.
3250 * Added public key verification process into client's protocol.c.
3251 The client now verifies the public key from user and saves
3252 it into ~./silc/serverkeys/ directory.
3254 Added into: clientutil.[ch]: silc_client_verify_server_key.
3256 * Changed SKE protocol's silc_ske_initiator_finish function
3257 to accept callback function that verifies the received public
3258 key. Removed old silc_ske_verify_public_key function.
3260 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3263 silc_pkcs_private_key[_data]_set.
3265 * Made the password and public authentication more cleaner in
3266 server's protocol.c.
3268 * Removed historic and obsolete protocol `channel_auth' from
3269 both client and server.
3271 * Removed wrong way of sending command status messages from
3272 server to client in server's command.c. The old way violated
3273 protocol specification.
3275 Changes to silccore/silccommand.[ch]: removed
3276 silc_command_encode_status_payload -> not needed anymore,
3277 changed silc_command_encode_payload_va to accept extra
3278 argument on variable argument list. The argument type must
3279 now be provided to the function. Also, added new function:
3280 silc_command_encode_reply_payload_va which is same as
3281 normal command_encode_payload_va except command status type
3282 is provided as extra argument.
3284 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Added ~./silc directory handling. The directory includes the
3287 public and private keys for the client.
3289 Added silc_client_check_silc_dir, silc_client_create_identifier
3290 and silc_client_load_keys.
3292 * Implemented SILC protocol compliant public key. Added public
3293 and private key saving to and loading from files.
3295 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3296 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3297 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3298 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3299 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3301 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3302 silc_pkcs_load_[public/private]_key.
3304 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added silc_server_get_route (route.[ch]) to get connection
3307 data for the fastest route for given ID.
3309 * Implemented INVITE command on client and server. The command
3310 were re-defined in the SILC Protocol Specification and the
3311 implementation now complies with the specification.
3313 * Implemented PING command on client and server.
3315 * Implemented NAMES command on client and server. The server side
3316 supports currently only normal server not router server yet.
3317 Some changes to NAMES definition in SILC protocol specification.
3319 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Implemented LEAVE command on client and server.
3323 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3324 again. This change was made to the protocol as well. Server
3325 should not violate the protocol specification anymore.
3327 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3330 was tested. SOCKS4 was not but should work anyway.
