1 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Moved the calling of ops->connect() from connect_to_server_final
4 into receive_new_id functin since that is the point when the
5 client is actually allowed to send traffic to network. The
6 affected file is lib/silcclient/client.c.
8 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
11 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
12 (if needs broadcasting) instead of broadcasting the packets one
13 by one which would make a burst in the network traffic.
15 * Added `broadcast' argument to the functions in silcd/server.[ch]
16 silc_server_create_new_channel[_with_id] to indicate whether
17 to send New Channel packet to primary router.
19 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Added new function into the silcd/server.[ch] files:
22 silc_server_create_new_channel_with_id to create new channel with
23 already existing Channel ID.
25 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
26 lib/silccore/silcpacket.h. This packet is used t send list of
27 Set Mode payloads inside one packet. Server uses this to set
28 the modes for the channels and clients on those channels, that it
29 announced to the router when it connected to it. The protocol
30 specification has been updated accordingly.
32 * The silc_server_new_channel did not handle the packet coming
33 from normal server as it normally does not send that. However,
34 when it announces its channels it does send it. Implemented
37 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
38 into the file lib/silccore/id.h.
40 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Fixed memory leaks in the functions silc_idlist_del_client,
43 silc_idlist_del_channel and silc_idlist_del_server in the file
44 silcd/idlist.c. All of those leaked like a sieve.
46 * Fixed some small memory leaks in the client's function
47 silc_client_notify_by_server.
49 * Added functions into silcd/server.c: silc_server_announce_clients,
50 silc_server_announce_channels and silc_server_announce_server.
51 These functions are used by normal and router server to announce
52 to its primary router about clients, channels and servers (when
53 router) that we own. This is done after we've connected to the
56 These functions effectively implements the following packet types:
57 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
58 and SILC_PACKET_NEW_ID_LIST.
60 * Added new functions into the silcd/packet_receive.[ch]:
61 silc_server_new_id_list, silc_server_new_channel_list and
62 silc_server_new_channel_user_list to handle the incoming
63 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
65 * Added support of changing Channel ID in the function
66 silc_server_replace_id. If the server that announces a channel
67 to the router already exists in the router (with same name but
68 with different Channel ID), router is responsible to send
69 Replace ID packet to the server and force the server to change
70 the Channel ID to the one router has.
72 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
73 client that the Channel ID has been changed by the router. The
74 normal server sends this to the client. Client must start using
75 the new Channel ID as the channel's ID.
77 Implemented handling of this new type into lib/silcclient/client.c
78 into the function silc_client_notify_by_server.
80 * Added new function silc_idlist_replace_channel_id into the files
81 silcd/idlist.[ch] to replace the Channel ID.
83 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Call silc_server_command_identify_check always when processing
86 the IDENTIFY command in silcd/command.c
88 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
91 send keepalive packets. The packet can be sent by clients,
94 Added function silc_socket_set_heartbeat into the file
95 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
96 If not set, the heartbeat is not performed. The actual
97 heartbeat is implemented in the low level socket connection
98 library. However, application is responsible of actually
101 Added silc_server_send_heartbeat to send the actual heartbeat
102 packet into silcd/packet_send.[ch]. Server now performs
103 keepalive with all connections.
105 * Added silc_task_get_first function into lib/silcutil/silctask.c
106 to return the timeout task with shortest timeout. There was a bug
107 in task unregistration that caused problems. TODO has been
108 updated to include that task system must be rewritten.
110 * The client library will now resolve the client information when
111 receiving JOIN notify from server for client that we know but
112 have incomplete information.
114 * Rewrote parts of silc_server_remove_from_channels and
115 silc_server_remove_from_one_channel as they did not remove the
116 channel in some circumstances even though they should've.
118 * Encryption problem encountered in server:
120 The LEAVE command used to send the Channel Key packet to the
121 router immediately after generating it. However, the code
122 had earlier sent Remove Channel user packet but not immediately,
123 ie. it was put to queue. The order of packets in the router
124 was that Channel Key packet was first and Remove Channel User
125 packet was second, even though they were encrypted in the
126 reverse order. For this reason, MAC check failed. Now, this
127 is fixed by not sending the Channel Key packet immediately but
128 putting it to queue. However, this is more fundamental problem:
129 packets that are in queue should actually not be encrypted
130 because packets that are sent immediately gets encrypted
131 actually with wrong IV (and thus MAC check fails). So, packets
132 that are in queue should be encrypted when they are sent to
133 the wire and not when they put to the queue.
135 However, the problem is that the current system has not been
136 designed to work that way. Instead, the packet is encrypted
137 as soon as possible and left to the queue. The queue is then
138 just purged into wire. There won't be any fixes for this
139 any time soon. So, the current semantic for packet sending
142 o If you send packet to remote host and do not force the send
143 (the packet will be in queue) then all subsequent packets to the
144 same remote host must also be put to the queue. Only after the
145 queue has been purged is it safe again to force the packet
148 o If you send all packets immediately then it safe to send
149 any of subsequent packets through the queue, however, after
150 the first packet is put to queue then any subsequent packets
151 must also be put to the queue.
153 Follow these rules and everything works fine.
155 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Added new function silc_server_remove_clients_by_server to
158 remove all client entries from ID list when the server connection
159 is lost. In this case it is also important to invalidate all
160 client entires as they hold the invalid server entry. This
161 fixes fatal bug when server has lost connection and will reconnect
164 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Made some sanity checks to silc_server_daemonise like to check
167 whether the requested user and group actually exists.
169 * Added sanity check to SKE's silc_ske_responder_finish to check
170 that the public and private key actually is valid.
172 * Invalidate the client's nickname when receiving Replace ID
173 packet and the Client ID is being replaced. This means that the
174 server will query the nickname if someone needs it (client)
177 * Sort the ID Cache in client library when the ID Cache data
178 has changed (needs sorting).
180 * Do not allow for SILC client to create several connections to
181 several servers. The client does not support windows right now
182 and generating multiple connections causes weird behaviour.
184 Irssi-silc client does support windows and can handle several
185 connections without problems, see: www.irssi.org and SILC plugin.
187 * Fixed some places where client was added to the IDList. The
188 rule of thumb is following (in order to get everything right):
189 If the client is directly connected local client then the
190 `connection' argument must be set and `router' argument must be
191 NULL to silc_idlist_add_client function. If the client is not
192 directly connected client then the `router' argument must
193 bet set and the `connection' argument must be NULL to the
194 silc_idlist_add_client function.
196 * The funtion silc_server_packet_send_local_channel actually did
197 not check whether the client was locally connected or not. It
198 does that now. Fixed a bug related to LEAVE command.
200 * Fixed Remove Channel User payload parsing bug in server's
201 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
203 * The server's silc_server_save_channel_key now checks also the
204 global ID list for the channel as it might not be in the local
205 list. Fixed a bug related to LEAVE command.
207 * Is this the end of the [<unknown>] buglet that has been lurking
208 around for a long time? A little for loop fix in server's
209 silc_server_command_whois_parse that is used by both IDENTIFY
210 and WHOIS command. At least, this was a clear bug and a cause
211 of one type of [<unknown>] buglet.
213 * WHOIS and IDENTIFY commands call the function
214 silc_server_command_[whois/identify]_check function even if
215 we are not router server.
217 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Added --with-gmp configuration option. If set the GMP
220 is always compiled in the SILC source tree. If not set then
221 it is checked whether the system has the GMP3 installed. If
222 it has then the GMP won't be compiled (the system's headers
223 and library is used), if it doesn't have it then the GMP is
224 compiled in the SILC source tree.
226 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
228 * Changed RSA private exponent generation to what PKCS #1
229 suggests. We try to find the smallest possible d by doing
230 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
231 not security fix but optimization.
233 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Added new config entry [Identity] to fork the server and run
236 it as specific user and group. A patch from Bostik.
238 * Imported Dotconf configuration library into lib/dotconf.
239 This will be used to create the SILC configuration files later.
240 It will appear in the distsribution after this commit.
242 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * A big code auditing weekend happening. Auditing code for
245 obvious mistakes, bugs and errors. Also, removing any code
248 Removed files for being obsolete:
250 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
251 inline in the file lib/silcutil/silcbuffer.h)
253 o lib/silcutil/silcbufutil.c (the header has inline versions)
255 Changed code to fix possible error conditions:
257 o The buffer formatting routines now check that the destination
258 buffer really has enough space to add the data. This applies for
259 both buffer formatting and unformatting
260 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
261 unformatting was changed to accomodate following rules:
262 XXX_*STRING_ALLOC will allocate space for the data into the pointer
263 sent to the function while XXX_*STRING will not allocate or copy
264 the data into the buffer. Instead it sets the pointer from the
265 buffer into the pointer sent as argument (XXX_*STRING used to
266 require that the pointer must be allocated already). This change
267 makes this whole thing a bit more consistent and more optimized
268 (note that the data returned in the unformatting with XXX_*STRING
269 must not be freed now). The routines return now -1 on error.
271 o Tried to find all code that use buffer_format and buffer_unformat
272 and added return value checking to prevent formatting and
273 especially unformatting errors and possible subsequent fatal
276 o Changed ske->x and ske->KEY to mallocated pointers in
277 lib/silcske/silcske.h. Fixed possible data and memory leak.
279 o Added return value checking to all *_parse* functions. Fixed
280 many memory leaks as well.
282 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
283 so that buffer overflows would not happen. All code now also
284 checks the return value as it can fail.
286 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Added reconnection support to server if the normal server looses
289 its connection to the router (for example if router is rebooted).
290 The server performs normal reconnection strategy implemented
291 to the server. Affected file silcd/server.c.
293 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Added new packet type SILC_PACKET_SET_MODE that is used to
296 distribute the information about changed modes (for clients,
297 channels and clients channel modes) to all routers in the
298 network. Updated the protocol specification accordingly.
300 Added functions into silcd/packet_send.c and
301 silcd/packet_receive.c: silc_server_send_set_mode,
302 silc_server_set_mode.
304 Added new files silcmode.[ch] into lib/silccore that implements
305 the encoding and decoding of Set Mode Payload. Added new type
306 SilcSetModePayload. Moved the definitions of different modes
307 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
309 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
311 * Oops, a little mistake in server's connection authentication
312 protocol. The protocol is not ended with FAILURE but with
313 SUCCESS if the authentication is Ok. :) Affected file is
316 * Implemented NICK_CHANGE notify handling in server in the file
317 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
318 the local clients on the channel. After the changing nickname
319 in router environment snhould work and the [<unknown>] nickname
320 should appear no more.
322 The silc_server_replace_id function that receives the Replace ID
323 payload now sends the NICK_CHANGE notify type also in the file
324 silcd/packet_receive.c
326 * Changed WHOIS and IDENTIFY command to support the maximum amount
327 of arguments defined in protocol specs (3328 arguments). This
328 fixed a bug that caused problems when there were more than three
331 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Added extra parameter, command identifier, to the
334 silc_client_send_command so that explicit command identifier
337 Changed that ID list routines uses specific command identifier
338 when sending WHOIS/IDENTIFY requests to the server so that they
339 can be identified when the reply comes back.
341 Affected files lib/silcclient/command.[ch],
342 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
344 * Added `sender' argument to silc_server_packet_send_to_channel
345 to indicaet the sender who originally sent the packet to us
346 that we are now re-sending. Ignored if NULL. Affected file
347 silcd/packet_send.[ch].
349 * Added some server statistics support in silcd/server_internal.h
350 SilcServerStatistics structure and around the server code. Also
351 send some nice statistics information when client is connecting
354 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Fixed channel ID decoding in server's JOIN command reply in
357 silcd/command_reply.c
359 * Fixed braodcasting of replace ID payload to not to send it if
360 we are standalone server in silcd/packet_receive.c.
362 * Fixed all channel message sending routines to not to send
363 packets to clients that has router set, since they are routed
364 separately in the same function earlier. Affects file
365 silcd/packet_send.c and all channel packet sending functions.
367 * In USERS reply, res_argv[i] are not allocated, the table
368 is allocated. Thus changed that free the table, not its
371 * In server's whois_check and identify_check if the client is
372 locally connected do not send any WHOIS commands - they are not
375 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Fixed some minor bugs in client when sending WHOIS command. The
378 arguments was in wrong order.
380 * Removed statis function add_to_channel from server in
381 silcd/command.c that was previously used with the joining but
384 * Tested USERS command in router environment successfully with two
385 routers, two servers and two clients.
387 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Reorganized the USERS command and command reply in client library
390 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
391 When the command is given by user we register a pending command
392 callback that will reprocess the command after the reply has been
393 received from the server. When reprocessing the packet we then
394 display the information. Thus, the USERS information is displayed
395 now in the command callback instead of in the command reply
396 callback. The processing of the command is same as previously
397 when server has sent the command reply in the JOINing process.
399 * Added to USERS command in silcd/command_reply.c to join the client,
400 we didn't use to know about, to the channel after we've created
401 a client entry for it. Also, for clienet we did know already still
402 check whether it is on the channel or not and add it if not.
404 * Removed silc_server_command_join_notify as the function and its
407 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * Changed the client's pending command handling to the same as the
410 server's pending command handling. It is also now possible to
411 execute command reply functions from other command reply
412 function as the function callbacks for commands and command
413 replies are one and same. The pending commands are not static
414 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
415 in client connection context. Thus, pending commands are server
416 connection specific as it is convenient.
418 Changed the function silc_client_command_pending and
419 silc_client_command_pending_del and added new function
420 silc_client_command_pending_check. Removed the
421 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
424 * Added cmd_ident, current command identifier, to the client
425 connection context in lib/silcclient/client.h to keep track on
426 command identifiers used in command sending. Client's command reply
427 function handling now supports the mandatory command identifiers.
429 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
430 funtions in client to fully support pending command callbacks.
432 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
433 as one of the arguments to the application in the command reply
436 * NOTE: The FORWARDED flag is depracated. It used to be depracated
437 before first releasing SILC but came back. Now it is removed again
438 and should come back nomore. The FORWARDED flag was used only
439 by the JOINing procedure by forwarding the command packet to router.
440 Now, the JOINing procedure has been changed to more generic (due
441 to various router environment issues) and FORWARDED is not needed
442 anymore for anything. The protocol specification is yet to be
445 Now, removed silc_server_packet_forward from server and the flag
446 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
448 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Renamed NAMES command to USERS command. The NAMES was named that
451 due to historical reasons. Now it is renamed. Also, rewrote
452 parts of the USERS command. The nickname list is not sent anymore
453 by the server. Only Client ID and mode lists are sent in the USERS
454 command. Changed this also to the protocol specification.
456 The client now resolves the names and stuff after it receives
457 the USERS list from the server when joining to the channel.
459 * WHOIS and IDENTIFY commands has been changed to support multiple
460 Client ID's per command. One can now search for multiple users
461 in the network by sending only one WHOIS or IDENTIFY command.
462 Changed the code and the protocol specifications.
464 * Removed silc_server_command_identify_parse and changed that IDENTIFY
465 uses silc_server_command_whois_parse to parse the request. */
467 * If normal server, do not parse the WHOIS and IDENTIFY requests
468 before sending it to the router. Saves some time.
470 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Fixed JOIN command on client library. Wrong number of arguments
473 used to crash the client.
475 * Added silc_server_channel_has_global function to check whether
476 channel has global users or not.
478 * Added silc_server_channel_has_local function to check whether channel
479 has locally connected clients on the channel.
481 * The silc_server_remove_from_one_channel now checks whether the
482 channel has global users or not after given client was removed from
483 the channel. It also checks whether the channel has local clients
484 on the channel anymore. If it does not have then the channel entry
485 is removed as it is not needed anymore.
487 * The silc_server_notify now checks on JOIN notify whether the joining
488 client is one of locally connected or global. If it is global then
489 the channel has now global users on the channel and that is marked
490 to the channel entry. Also, it now saves the global client to
491 global list who is joining and JOINs it to the channel. This is
492 for normal server, that is.
494 Changed silc_server_send_notify_on_channel,
495 silc_server_packet_relay_to_channel and
496 silc_server_packet_send_to_channel check if we are normal server
497 and client has router set (ie. global client) do not send the
498 message to that client, as it is already routed to our router.
500 * Implemented LEAVE notify type handling in silc_server_notify
503 * Tested LEAVE command in router environment successfully. Tested
504 with two routers, two servers and two clients.
508 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
510 * Implemented SIGNOFF notify type handling in silc_server_notify
513 * silc_server_remove_id now removes the client entry from all channels
514 it has joined and thusly sends SIGNOFF notify type.
516 * Rewrote the NAMES list generation in server by removing two excess
517 loops. The lists are created now inside one loop.
519 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * silc_server_remove_channel_user checks now also global list
522 for channel and client.
524 * silc_server_new_channel_user checks now both local and global
525 list for channel and client. Fixed a bug in client id decoding.
526 Used to decode wrong buffer.
528 * silc_server_channel_message checks now both local and global
529 list for channel entry.
531 * Tested channel joining (hence JOIN) in router environment
532 successfully. Tested with two routers, two servers and two
535 * Tested channel message sending in router environment successfully.
537 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Added silc_server_save_channel_key into server.[ch] to save the
540 received channel key in Channel Key payload processing. It is
541 also used in JOIN command reply handling.
543 Equivalent function silc_client_save_channel_key added into
544 client.[ch] into client library.
546 * Changed JOIN command reply to send information whether the channel
547 was created or not (is existing already) and the channel key
548 payload. Changed protocol specs accordingly.
550 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
551 the request was sent by ID and not by nickname. Crashed on
554 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
557 now correctly save the received data.
559 * silc_server_free_sock_user_data now notifies routers in the
560 network about entities leaving the network.
562 At the same time implemented functions silc_server_remove_id
563 and silc_server_send_remove_id to receive and send REMOVE_ID
564 packets. The packet is used to notify routers in the network
565 about leaving entities. The ID removed will become invalid in
568 * Added function silc_idlist_del_server into server. Removes and
569 free's server entry from ID list.
571 * silc_server_private_message function now checks, if we are router,
572 that the destination ID really is valid ID, naturally.
574 * In router when NEW_ID packet is received (for new client) the
575 hash of the Client ID is saved in the ID Cache but the
576 client->nickname is set to NULL, instead of putting the hash
579 IDENTIFY command now also checks that client->nickname must be
580 valid. If it is not if will request the data from the server who
581 owns the client. Added new function
582 silc_server_command_identify_check.
584 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
585 to set the command to already allocated Command Payload.
587 * Tested private message sending in router environment with two
588 routers, two servers and two clients. Fixed minor bugs and now
591 * Fixed segfault from client's NAMES command. Used to crash if
594 * Forwarded packets must not be routed even if it is not destined
595 to the receiver. Changed server code comply with this.
597 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
599 * Added `require_reverse_mapping' boolean value to ServerParams
600 structure. If TRUE (not default) the server will require that
601 the connecting host has fully qualified domain name.
603 If the reverse mapping is not required and hostname could not be
604 found the IP address is used as hostname.
606 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Implemented version string checking to both client and server.
609 The check is incomplete currently due to the abnormal version
610 strings used in development version of SILC.
612 * Changed all command functions in server to use the new
615 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Changed char *data to unsigned char *data in ID Cache system to
618 support binary data as ID Cache data. Changed code to support
619 binary data in lib/silccore/idcache.c.
621 * Renamed silc_server_packet_relay_command_reply to
622 silc_server_command_reply as it is normal packet receiving
623 function. Rewrote the function to accept command replys for
624 servers and not only for clients.
626 * Mark remote router always as registered server if we are connecting
627 to it. Otherwise, commands sent by the router to us are ignored.
629 * All ID List find routines now returns the ID Cache Entry pointer
630 as well if requested.
632 * WHOIS command works now in router environment, tested with two
633 routers, two servers and two clients.
635 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
636 in router environment (as it is almost equivalent to WHOIS) but
637 hasn't been tested thoroughly. Added new functions:
639 silc_server_command_identify_parse
640 silc_server_command_identify_send_reply
641 silc_server_command_identify_from_client
642 silc_server_command_identify_from_server
644 * Disabled route cache adding because adding two different ID's with
645 same IP replaces the old cache entry thus giving wrong route.
646 The entry->router->connection is always the fastest route anyway
647 so route cache may not be needed. Of course, new routes maybe
648 established after receiving the ID when the entry->router->connection
649 might not be anymore the most optimal.
651 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * Add route cache for received ID for fast routing.
655 * Added silc_server_packet_route to route received packet on router
656 that is not destined to us.
658 * Renamed silc_server_get_route to silc_server_route_get.
660 * Added id_string and id_string_len fields into SilcServer to
661 include encoded ServerID for fast comparing without excess
662 encoding of the ID's.
664 * Cleaned up WHOIS command on server side. Added following static
667 silc_server_command_whois_parse
668 silc_server_command_whois_check
669 silc_server_command_whois_send_reply
670 silc_server_command_whois_from_client
671 silc_server_command_whois_from_server
673 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
674 arguments in command replies. All command functions should be
675 updated to use this macro.
677 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Minor typo fixes on command reply handling on server.
681 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Added silc_server_command_add_to_channel internal routine to add
684 the client to the channel after router has created the channel and
685 sent command reply to the server.
687 * Added generic silc_server_send_command to send any command from
690 * Use static buffer with ID rendering instead of duplicating data.
692 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Fixed a channel user mode bug when joining to a channel server gave
695 everybody channel founder rights, oops.
697 * We mark ourselves as the router of the incoming server connection
698 if we are router ourselves. This way we can check in some packet
699 sending functions whether it is locally connected server. For
700 incoming router connections we put NULL.
702 * For router sending packets locally means now always sending the
703 packet cell wide; to local clients and local servers. For normal
704 server sending packet locally means sending it to only local
707 * Fixed the JOIN command to really work in router environment. If the
708 channel is created it is always created by the router. Router is
709 also responsible of making the initial joining to the channel,
710 sending JOIN notify to the sending server and distributing
711 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
712 does not exist server doesn't do anything else but forward the
713 command to the router which performs everything.
715 * Added silc_server_send_channel_key function to send the Channel Key
718 * Added silc_server_create_channel_key to create new channel key. The
719 channel key is now re-generated everytime someone joins or leaves
720 a channel, as protocol dictates. Note: channel->key_len is the
723 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
725 * Splitted server.[ch] finally. Created now packet_send.[ch] and
726 packet_receive.[ch] to separate packet sending and receiving
727 routines. The server.[ch] now includes everything else including
728 actual packet processing (writing and reading data) and other
731 Renamed silc_server_private_message_send_internal to
732 silc_server_send_private_message. The routine is still though
733 used only to relay private messages as server does not send
734 private messages itself.
736 Renamed silc_server_new_channel to silc_server_create_new_channel
737 and added new function sicl_server_new_channel that handles the
738 incoming New Channel packet. Added also new sending function
739 silc_server_send_new_channel to send New Channel Payload.
741 * Added new function silc_server_notify to process incoming notify
742 packet to the server/router. Server may then relay the notify
743 to clients if needed.
745 * Added new function silc_server_new_channel_user to process incoming
746 New Channel User packet. Router will redistribute the packet and
747 send JOIN notify to its local clients and locally connected servers
748 if needed. Normal server will send JOIN notify to its local client
749 on same channel when received this packet. Added also corresponding
750 sending function silc_server_send_new_channel_user to sent the
753 * Added boolean route argument to send_notif_to_channel and
754 packet_send_to_channel functions to attempt to route the packet
755 if it is TRUE and send only locally if it is FALSE.
757 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * silc_server_replace_id now broadcasts the received replace ID
760 packet if it is not broadcast packet already. The router must
761 broadcast to inform other routers about changed ID.
763 * Added backpointer to server's router into SilcServer context in
764 silcd/server_internal.h.
766 * Fixed silc_server_packet_broadcast to send correct broadcast
769 * The channel key is now distributed to the local client as soon
770 as it is received from the router (in router environment) so that
771 no other packet may be sent for the channel until client has
774 * silc_server_remove_channel_user now broadcasts the received
775 Remove Channel User packet if it is not broadcast packet already.
776 The router must broadcast to inform other routers about removed
779 * Added users field into SilcPacketContext that is a reference count
780 of the context. One can increase the reference count by calling
781 silc_packet_context_dup which is now changed to just increase the
782 reference count instead of duplicating the data. The reference
783 count is decresed by calling silc_packet_context_free that will
784 free the data after the reference count hits zero.
786 For now on the packet context and everything allocated into it
787 (including the raw packet from network) must be freed by calling
788 the new silc_packet_context_free function. Added also new function
789 silc_packet_context_alloc that must be used now to allocate the
790 context. This also means that if a routine is asynchronous from
791 silc_[client/server]_packet_parse_type the packet context must
792 be duplicated by calling silc_packet_context_dup. Otherwise it
793 gets free'd after silc_[client/server]_packet_parse_type returns.
794 Also, one must remember that if packet is duplicated then its
795 reference count must be decresed by calling the free function as
796 many times as it was duplicated.
798 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
799 from both client and server.
801 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Made joining to a channel working in router environment.
805 * Cleaned up JOIN command on server side and create function
806 silc_server_command_join_channel internal routine to make the
809 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Changed silc_command_pending list to SilcDList. Also, added
812 `ident' field to SilcServerCommandPending structure to identify
813 the reply and to call correct callback.
815 Added silc_server_command_pending_check function to replace the
816 corresnponding macro. The silc_command_pending list is not
819 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
820 to set identifier to previously allocated Command Payload. It
821 is used to set identifier for command when resending Command
824 * Added silc_command_payload_encode_payload to encode Command
825 Payload buffer from SilcCommandPayload structure.
827 * Added silc_argument_payload_encode_payload to encode Argument
828 payload buffer from SilcArgumentPayload structure.
830 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Changed WHOIS command to support router connection on server side.
833 The whois request is always sent to router unless the server is
834 standalone server. After server has received the reply from the
835 router will it send the reply to the client.
837 * Added silc_server_packet_broadcast into silcd/server.[ch] to
838 broadcast received broadcast packet. The function is used only
839 by router. The broadcast packet is always sent to the router's
842 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
843 render given ID to printable string, for log files for example.
845 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Made basic router to router connections working. At least they
848 can now connect to each other but nothing really works the way
849 they are supposed - yet.
851 * Added new initiator token to RouterConnection configuration
852 file in silcd/serverconfig.[ch]. It is used to tell whether we
853 are the initiator to the remote router or whether we'll expect
854 the other end to connect.
856 * Moved registering of listener task to silc_server_init, hence
857 the server starts listenning as soon as it is run, even if it
858 does not have connections to other routers. Let's see how well
861 * Changed default connection retry timeouts for more suitable in
864 * Removed cipher and such arguments from silc_idlist_add_client
865 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
866 Added new function silc_idlist_add_data to add the keys and stuff
869 * Added SilcIDListData structure and added it to SilcClientEntry
870 and SilcServerEntry as their first field in the structure. This
871 way we can explicitly cast the ID entries to the SilcIDListData
872 structure and get common data for the entries. In past, we had
873 to first check what type of connection it is and then cast it to
874 correct ID entry type. Now, we can directly cast the opaque
875 pointer to the SilcIDListData (no matter what ID entry it actually
876 is) and get the data needed.
878 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Wow, found a bug in scheduler. The scheduler uninitialized itself
881 in some circumstances even if threre were timeout tasks, though not
882 IO tasks, but tasks anyway. Now fixed.
884 * Defined SilcServerConnection structure to hold connection specific
885 stuff about directly connected servers and routers. The definition
886 is currently in silcd/server_internal.h. I thought about having
887 a bit more important role fro this struct but for now it is used
888 only when connecting to other server (or router actually).
890 * Added connecting retry support in server when connecting to
891 router(s). The retry feature implement exponential backoff
892 algorithm. Also, added SilcServerParams structure to hold default
893 parameters for server. For now, it include these retry settings
894 and are hard coded. After server is moded to be as Silc Server
895 Library this structure will be more important.
897 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Changed client librarys channel->clients table to SilcList and
900 changed code accordingly.
902 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Changed client's channel table to SilcList and changed code
905 accordingly. Also changed SilcChannelClientEntry to include back-
906 pointer to the channel so that client entry can use that structure
907 as list as well and we have fast cross-reference to the channel.
908 This change dramatically decreased the complexity of channel
909 handling with client entry and vice versa (removed one extra
910 loop when searching for channel entry from many functions).
912 * Changed server->sim from table to SilcDList and changed code
915 * NAMES command can now be used from user interface. It will show
916 the user list on the channel, neatly.
918 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
919 Code now saves realname of the user if it becomes available.
921 * Renamed configure.in to configure.in.pre and made ./prepare
922 script to automatically add correct version string to
923 configure.in which it creates from configure.in.pre.
925 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * NAMES command reply now shows users mode with the nickname when
930 * Moved silc_client_ch[u]mode[_char] functions from
931 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
932 place sucks, they are utility functions and should be in some
935 * Fixed some unsigned int's to unsigned short's. Patch by cras.
937 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
940 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Added TRQ (efficient deque and list library) into lib/trq. This is
945 a very good list library that is currently used in the SILC. Defined
946 SilcList API over the library because I didn't like the API very
947 much. See lib/trq/silclist.h for the API and examples of how to
948 use the API. Fixed various places in the code to use the new
949 SilcList API. The SilcList is meant for lists that has a structure
950 already defined as a list. It is not suitable to add just some
951 context to the list (in TRQ, the context is the list actually).
953 So, I defined SilcDList that can be used for the purpose where
954 predefined list structure does not exit. This can be used as
955 such list. Now some context just can be added to the SilcDList.
956 Currently this list is not used in the SILC just yet, though there
957 are a lot places where this can replace dynamically allocated
958 tables and I will fix these places, later, to use SilcDList.
959 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
960 and use TRQ internally).
962 Also fixed some annoying warning messages that the original TRQ
963 code generated. Also minor changes to TRQ's Makefile.in.
965 * Added support for querying by Client ID to both WHOIS and
966 IDENTIFY commands into server, as required by the protocol.
968 * Removed method function pointers from SilcBuffer structure. They
969 weren't used to anything and just increased the context size for
970 no good reason. This change also made silc_buffer_alloc and
971 silc_buffer_free functions inline functions.
973 * Disabled command flooding detection support until it's fixed so
974 that it accepts commands in but does not execute them more than once
977 * Added silc_net_localhost(), to return local hostname, into
978 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
979 that must be initialized before calling silc_client_init.
981 * Added new function: silc_server_send_notify_on_channels to send
982 notify messages to all channels client has joined. It is assured
983 that the message is sent only once per client.
985 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
986 lib/silcutil/silcutil.[ch] as silc_format function. The new
987 function is generic and is used by server as well, not only by
988 the logging routines.
990 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
991 the provided version string was not acceptable. Added new function:
992 silc_ske_check_version into lib/silcske/silcske.h. The function
993 must be implemented by the application (client or server) and it
994 does not reside in the SKE library. The function checks the version
995 string remote end sent.
997 * Added back pointers (to opaque context and to SilcSocketConnection)
998 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1000 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1001 duplicate packet context structure.
1003 * Changed `notify' client operation to send same arguments as client
1004 receives from server except for ID's. ID's are mapped to correct
1005 ID entry and that is returned. Also, if channel entry is not sent
1006 by server but the notify is for channel the channel entry is sent
1007 to application (otherwise application doesn't know that it is for
1008 channel (library gets it from packet's Destination ID)).
1010 * Added silc_client_remove_from_channels into client library to
1011 remove a client from all channels it has joined to. Used when
1012 received SIGNOFF notify from server. Added also new function
1013 silc_client_replace_from_channels to replace old ID entry with
1014 new ID entry on all channels. Used when received NICK_CHANGE
1017 * Fixed ID Cache list handling in silc_idlist_get_client in
1018 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1019 to get (or query) client by ID.
1021 * Updated TODO list.
1023 * Added connection authentication status message defined by the
1024 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1025 support for these into the code in client and server side.
1027 * Added generic function silc_client_send_command to send any command
1028 with variable argument list. Application should use this function
1029 to send commands if the command functions provided by the library
1030 does not suite for the application's user interface needs.
1032 * Added new `failure' client operation. Application is notified about
1033 received failure packet if client is executing a protocol. In this
1034 case the protocol's execution has failed.
1036 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1037 is required by the protocol.
1039 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1040 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1043 * Added status flag to SilcSKE object to indicate realtime status
1044 of the SKE protocol.
1046 * Application receives now exactly same command reply arguments as
1047 the library receives from server. However, if ID is received the
1048 corresponding ID entry is returned to the application (eg. Client
1049 ID is mapped to correct SilcClientEntry entry and that is returned).
1050 Changed command_reply client operation due to this change.
1052 * Changed all ID's in commands and in command replys as ID Payloads.
1053 Change affected both client and server side codes.
1055 All ID's sent in SILC network (with execption of ID's in SILC
1056 Packet header) are sent in ID Payload to support variable length
1059 * Server now notifies nick changes and notifies all clients on
1060 the channels about the new nickname (about the new Client ID,
1063 * Implemented CMODE command to change channel modes. Supports all
1064 channel modes defined by the protocol specs except ban and invite
1065 lists. (Also, private channel key mode is supported but support for
1066 setting private channel key in client is missing, thus, this mode
1067 has no effect on client side (except that server requires that the
1068 client uses private channel key and normal channel traffic does not
1071 Also, invite mode works per se, but INVITE command does not work
1072 yet correctly, so you can set channel as invite only channel but
1073 inviting clients to the channel does not work (it is yet to be
1074 thought what's the best way to do it).
1076 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1077 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1078 Implemented CUMODE command to change user's mode on the channel.
1079 Supports all modes defined by the protocol specs.
1081 * Added NAMES command reply to return users modes on the channel.
1083 * Removed unnecessary and slow ciphers from lib/silccrypt.
1085 * Set SO_KEEPALIVE option to connection sockets by default.
1087 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1089 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1090 redefined the Notify Payload into protocol specs.
1092 * Added silc_id_payload_parse_id to get ID directly from raw
1095 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1098 accept searching by Client ID as well.
1100 * Added support for LEAVE and SIGNOFF notify types in client library.
1102 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1103 to parse ID Payload from raw data.
1105 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1107 * Added flags parameter into silc_ske_assemble_security_properties
1108 function in lib/silcske/silcske.[ch].
1110 * Changed notify client operation to fit better for notify messages
1111 sent by server. The notify payload received from server is now
1112 passed to the application (after parsing it to SilcNotifyPayload).
1113 It is application's responsibility to retrieve the arguments
1114 from the payload and show the message the way it wants. The message
1115 sent by server is implementation specific.
1117 * Changed public keys to comply with the protocol specification.
1118 Old public keys are not supported anymore and are not compatible.
1120 * Removed nickname from Channel Payload as the latest draft removed
1121 it. The client must resolve the nickname from the NAMES command
1122 reply received when it joined the channel.
1124 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1126 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Fixed some errors in protocol specification drafts.
1130 * Created lib/silccore/silcnotify.c to implement Notify Payload
1131 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1132 generic payloads described by protocol specifications. The file
1133 includes implementations for ID Payload and Argument Payload.
1135 * Changed Command Payload implementation to use the new Argument
1136 Payload. Changed command_xxxx_payload to command_payload_xxxx
1137 to comply with SILC coding conventions.
1139 * Added suppport for Argument Payload handling in Notify Payload
1140 implementation as protocol requires it. Added the new support
1141 into server and client lib as well.
1143 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Added support for multiple nicknames on same channel. [n] is
1146 added locally to the nickname if there are more than one same
1147 nicknames on the channel.
1149 * Server now sends all nicknames that matched WHOIS request.
1150 Client also shows the list received from server.
1152 * Added TOPIC command to client side. User can now set and show
1153 current topic on channel.
1155 * Added MOTD command to client and server. Also, server sends the
1156 motd when client connects to the server.
1158 * Changed version strings to comply ISO 8601.
1160 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Fixed protocol error handling in client library. It should now
1163 cope even if the SKE fails for some reason.
1165 * Made new protocol specification drafts for submitting to IETF.
1167 * Implemented TOPIC command to server in silcd/command.c.
1169 * Added two new notify types into lib/silccore/silcnotify.h:
1170 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1171 notify nickname change and topic setting/change on a channel.
1173 * API change of command_reply operation in client library. The
1174 application gets now the status type received from server as well.
1176 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1180 * Cras fixed and optimized the packet handling even further and
1181 it should work now. Minor change to the prototype of function
1182 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1184 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added new function into lib/silcutil/silcschedule.[ch]:
1187 silc_schedule_with_fd to select() a specified fd. The function
1188 returns after timeout expires or data arrives or goes. The
1189 function is used by packet routines to wait that all data is
1190 received from network.
1192 * Fixed data reading from network in lib/silccore/silcpacket.c.
1193 The code now assures that all data is read from the fd and then
1194 continues packet processing. This was a bug fix since the code
1195 used to drop some data in some circumstances.
1197 * Added new function into lib/silcclient/client.[ch]:
1198 silc_client_start_key_exchange to start key exchange after
1199 connection has been established to server. The code internally
1200 now uses this funtion but its main purpose was to provide it
1201 for applications that perform their own connecting. After
1202 application has created a connection it merely calls this
1203 function to start the key exchange between client and server.
1204 The library takes care of everything else after that.
1206 Updated also lib/silcclient/README to explain the usage of
1209 * Do not send to application information that connection has
1210 been established. Application gets notified it by connect
1213 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Applied cras's patch to add silc_schedule_one function. The
1216 function runs scheduler once and returns.
1218 * Fixed the scheduler after cras messed it up. The timeout
1219 handling works now as it's supposed to work.
1221 * Added into lib/silccore/ silcnotify.h to include notify
1222 message types support. Changed silc_server_send_notify*
1223 functions, in server.[ch], to support those new notify types.
1224 Added the support for the notify types into client library,
1225 as well. Added new notify client operation into ops.h in
1228 * Changed silc_server_packet_send_to_channel to send normal
1229 packets instead of just channel message packets. The function
1230 is now used to send the notify packets to channels. It is not
1231 used to send channel message packets anymore, as server never
1234 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1235 va_arg()s as it seems to require it nowadays. I guess, if SILC
1236 is compiled with older va_arg() the new code should work anyway.
1238 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Splitted core library. Core library (lib/silccore) includes
1241 now only SILC protocol specific core (and common) components.
1242 Created new utility library (lib/silcutil) that includes more
1243 generic purpose stuff. The stuff for util library was taken
1244 from the old core library. This was minor and easy split.
1246 * Created SILC Client Library (lib/silcclient) that includes
1247 implementation of the SILC client without user interface. This
1248 was major move from silc/ directory. The code has been changed
1249 so that it is transparent towards the user interface. The
1250 silc/ directory includes now the same user interface as before
1251 and it uses the new client library. Read lib/silcclient/README.
1252 Basicly, the client library performs everything else related
1253 to SILC except user interface handling. Also, configuration
1254 files are considered to be part of user interface and library
1255 does not handle them.
1257 This change also changed a lot of structures, function naming etc.
1258 Most important change was that SilcClientWindow object was
1259 renamed to SilcClientConnection in the client library. Created
1260 also new file lib/silcclient/ops.h. Also added new files
1261 silc/local_command.[ch] and silc/client_ops.[ch].
1263 All these changes were made to make it easier for user interface
1264 designers to create what ever user interface for the SILC client
1267 It is also expected that the server will be moved to lib
1268 directory as well and SILC Server Library will be created;
1269 sometimes in the future.
1271 * Removed Local commands from lib/silccore/silccommand.h as
1272 they are application specific and new client library does not
1273 handle any of those anymore.
1275 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1276 old client implementation in silc/.
1278 * Added support for callback functions in SILC_LOG_* macros.
1279 Application can now set its own callbacks that will be called
1280 instead of using the default functions that will always print
1281 the debug messages to stderr (or stdout). Also, debugging can
1282 now be disabled by setting silc_debug to FALSE and re-enabled by
1283 setting it to TRUE. Note, that logging will still work even
1284 if debugging is disabled.
1286 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1287 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1288 silc_log_reset_debug_callbacks.
1290 * To enable debugging in silc client one must give now -d
1291 option on command line.
1293 * Changed silc_schedule_init to automatically allocate task queues
1294 if they are not allocated before calling it.
1296 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added GMP 3.1 into math library.
1300 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1303 a channel in SILC network. The packet is used by servers and
1304 routers to notify other routers that user has left a channel.
1305 This little feature was missing until now. Added the feature
1306 to protocol specification as well.
1308 Added functions: silc_server_send_remove_channel_user and
1309 silc_server_remove_channel_user into server.[ch].
1311 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1312 lib/silccore/silcpacket.h. However, they are not implemented
1315 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Fixed joining to a channel and sending channel messages
1318 between server and router. The channel message sending should
1319 now work inside a cell.
1321 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Fixed the private message sending between server and router.
1324 The private message sending should now work inside a cell.
1326 * Added silc_server_replace_id into server.[ch] to replace
1327 existing ID in the SILC network.
1329 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1330 and silc_idlist_replace_server_id into idlist.[ch] in server.
1332 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Fixed the server to server connections. Server can again now
1335 connect to router. Router to router connections probably does
1338 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1340 * Added dynamic protocol registering support. Now protocols can
1341 registered and unregistered on the fly. Patch by cras.
1343 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Added lib/contrib directory to hold routines that some platforms
1346 don't have but are needed by SILC.
1348 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1349 into lin/contrib to provide getopt() and getopt_long() for
1350 those who don't have it.
1352 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1354 * Added AWAY command to client. When away message is set and
1355 client receives a private message packet the client automatically
1356 replies to the sender with the away message.
1358 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1359 bug seemed to be the cause of recent problems when compiling
1362 * Added version detection support to SKE protocol specification
1363 and added the new changes to the SKE implementation as well.
1364 There were other minor changes in the SKE protocol as well.
1366 Many changes in lib/silcske/silcske.[ch] and in
1367 lib/silcske/payload.[ch].
1369 * Added ^U functionality, clear input line. Patch from cras.
1371 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Mainly small bugfixes on core library. Fixed some debugging
1374 logging and buffer overflow in silclog.c.
1376 * Updated config.sub and config.guess on the distribution tree.
1378 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Added command lagging support in server. Client may execute
1381 commands now only once in two seconds.
1383 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Optimized packet reception. MAC computation and checking is now
1386 also more optimized. A lot previously duplicated code is now
1387 used as generic by both client and server.
1389 * Fixed key pair generation in clientutil.c
1391 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Added into lib/silccore/silcbufutil.[ch] new function;
1394 silc_buffer_realloc.
1396 * Moved generic packet sending/encryption functions to
1397 lib/silccore/silcpacket.[ch] from client and server. Some
1398 rewriting of the functions.
1400 * Moved all generic packet reception/decryption functions to
1401 lib/silccore/silcpacket.[ch] from client and server. The
1402 packet processing is now much cleaner in both client and server.
1403 These were major changes in both client and server.
1405 * Created many common functions in server to do packet sending.
1406 Previously code were duplicated a lot, this has been removed
1409 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * Rewrote major parts of the ID cache system. Don't know
1412 whether it is better now or not but at least the API is more
1415 * Major rewrite on ID cache stuff on client because of the ID
1416 cache API changes. Added idlist.c to client.
1418 * Also major rewrite on ID cache stuff on server as well.
1419 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1420 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1421 in hand, instead they are all put into the ID cache system now.
1422 All server_idlist_* routines uses ID cache now instead of
1423 traversing its own lists (those lists does not exist anymore).
1424 SilcIDList though still exists. Also, SilcXXXEntry's are
1427 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Finally made the SKE implementation compliant to the protocol
1430 specification. All mp integers are now binary encoded as
1431 opposed being HEX encoded.
1433 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1436 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1437 functions: silc_[encode/decode]_pem. Also added function
1438 silc_encode_pem_file to PEM encode with newlines ('\n') for
1441 * SILC public keys are now encoded either PEM or binary. Same
1442 option is for private keys as well. By default private keys
1443 are binary encoded and public keys PEM encoded. Silly HEX
1444 encoding were removed.
1446 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1447 function to create fingerprints.
1449 * Fixed a bug in SHA1; does not change the original data anymore.
1451 * Partly implemented INFO command on client and server side.
1452 Fixed CLEAR command. Changes to SERVER command; show current
1453 server(s) when giving command without arguments. Added
1454 VERSION command to client.
1456 * Added check to server that unregistered connections cannot
1457 execute commands (unless it is specificly allowed).
1459 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Fixed screen refresh.
1463 * Fixed channel joining bug from client. On some circumstances
1464 client tried to join to a channel it had already joined.
1466 * Added public key verification process into client's protocol.c.
1467 The client now verifies the public key from user and saves
1468 it into ~./silc/serverkeys/ directory.
1470 Added into: clientutil.[ch]: silc_client_verify_server_key.
1472 * Changed SKE protocol's silc_ske_initiator_finish function
1473 to accept callback function that verifies the received public
1474 key. Removed old silc_ske_verify_public_key function.
1476 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1479 silc_pkcs_private_key[_data]_set.
1481 * Made the password and public authentication more cleaner in
1482 server's protocol.c.
1484 * Removed historic and obsolete protocol `channel_auth' from
1485 both client and server.
1487 * Removed wrong way of sending command status messages from
1488 server to client in server's command.c. The old way violated
1489 protocol specification.
1491 Changes to silccore/silccommand.[ch]: removed
1492 silc_command_encode_status_payload -> not needed anymore,
1493 changed silc_command_encode_payload_va to accept extra
1494 argument on variable argument list. The argument type must
1495 now be provided to the function. Also, added new function:
1496 silc_command_encode_reply_payload_va which is same as
1497 normal command_encode_payload_va except command status type
1498 is provided as extra argument.
1500 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Added ~./silc directory handling. The directory includes the
1503 public and private keys for the client.
1505 Added silc_client_check_silc_dir, silc_client_create_identifier
1506 and silc_client_load_keys.
1508 * Implemented SILC protocol compliant public key. Added public
1509 and private key saving to and loading from files.
1511 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1512 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1513 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1514 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1515 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1517 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1518 silc_pkcs_load_[public/private]_key.
1520 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Added silc_server_get_route (route.[ch]) to get connection
1523 data for the fastest route for given ID.
1525 * Implemented INVITE command on client and server. The command
1526 were re-defined in the SILC Protocol Specification and the
1527 implementation now complies with the specification.
1529 * Implemented PING command on client and server.
1531 * Implemented NAMES command on client and server. The server side
1532 supports currently only normal server not router server yet.
1533 Some changes to NAMES definition in SILC protocol specification.
1535 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Implemented LEAVE command on client and server.
1539 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1540 again. This change was made to the protocol as well. Server
1541 should not violate the protocol specification anymore.
1543 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1546 was tested. SOCKS4 was not but should work anyway.
