1 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new function into the silcd/server.[ch] files:
4 silc_server_create_new_channel_with_id to create new channel with
5 already existing Channel ID.
7 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
8 lib/silccore/silcpacket.h. This packet is used t send list of
9 Set Mode payloads inside one packet. Server uses this to set
10 the modes for the channels and clients on those channels, that it
11 announced to the router when it connected to it. The protocol
12 specification has been updated accordingly.
14 * The silc_server_new_channel did not handle the packet coming
15 from normal server as it normally does not send that. However,
16 when it announces its channels it does send it. Implemented
19 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
20 into the file lib/silccore/id.h.
22 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Fixed memory leaks in the functions silc_idlist_del_client,
25 silc_idlist_del_channel and silc_idlist_del_server in the file
26 silcd/idlist.c. All of those leaked like a sieve.
28 * Fixed some small memory leaks in the client's function
29 silc_client_notify_by_server.
31 * Added functions into silcd/server.c: silc_server_announce_clients,
32 silc_server_announce_channels and silc_server_announce_server.
33 These functions are used by normal and router server to announce
34 to its primary router about clients, channels and servers (when
35 router) that we own. This is done after we've connected to the
38 These functions effectively implements the following packet types:
39 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
40 and SILC_PACKET_NEW_ID_LIST.
42 * Added new functions into the silcd/packet_receive.[ch]:
43 silc_server_new_id_list, silc_server_new_channel_list and
44 silc_server_new_channel_user_list to handle the incoming
45 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
47 * Added support of changing Channel ID in the function
48 silc_server_replace_id. If the server that announces a channel
49 to the router already exists in the router (with same name but
50 with different Channel ID), router is responsible to send
51 Replace ID packet to the server and force the server to change
52 the Channel ID to the one router has.
54 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
55 client that the Channel ID has been changed by the router. The
56 normal server sends this to the client. Client must start using
57 the new Channel ID as the channel's ID.
59 Implemented handling of this new type into lib/silcclient/client.c
60 into the function silc_client_notify_by_server.
62 * Added new function silc_idlist_replace_channel_id into the files
63 silcd/idlist.[ch] to replace the Channel ID.
65 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Call silc_server_command_identify_check always when processing
68 the IDENTIFY command in silcd/command.c
70 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
73 send keepalive packets. The packet can be sent by clients,
76 Added function silc_socket_set_heartbeat into the file
77 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
78 If not set, the heartbeat is not performed. The actual
79 heartbeat is implemented in the low level socket connection
80 library. However, application is responsible of actually
83 Added silc_server_send_heartbeat to send the actual heartbeat
84 packet into silcd/packet_send.[ch]. Server now performs
85 keepalive with all connections.
87 * Added silc_task_get_first function into lib/silcutil/silctask.c
88 to return the timeout task with shortest timeout. There was a bug
89 in task unregistration that caused problems. TODO has been
90 updated to include that task system must be rewritten.
92 * The client library will now resolve the client information when
93 receiving JOIN notify from server for client that we know but
94 have incomplete information.
96 * Rewrote parts of silc_server_remove_from_channels and
97 silc_server_remove_from_one_channel as they did not remove the
98 channel in some circumstances even though they should've.
100 * Encryption problem encountered in server:
102 The LEAVE command used to send the Channel Key packet to the
103 router immediately after generating it. However, the code
104 had earlier sent Remove Channel user packet but not immediately,
105 ie. it was put to queue. The order of packets in the router
106 was that Channel Key packet was first and Remove Channel User
107 packet was second, even though they were encrypted in the
108 reverse order. For this reason, MAC check failed. Now, this
109 is fixed by not sending the Channel Key packet immediately but
110 putting it to queue. However, this is more fundamental problem:
111 packets that are in queue should actually not be encrypted
112 because packets that are sent immediately gets encrypted
113 actually with wrong IV (and thus MAC check fails). So, packets
114 that are in queue should be encrypted when they are sent to
115 the wire and not when they put to the queue.
117 However, the problem is that the current system has not been
118 designed to work that way. Instead, the packet is encrypted
119 as soon as possible and left to the queue. The queue is then
120 just purged into wire. There won't be any fixes for this
121 any time soon. So, the current semantic for packet sending
124 o If you send packet to remote host and do not force the send
125 (the packet will be in queue) then all subsequent packets to the
126 same remote host must also be put to the queue. Only after the
127 queue has been purged is it safe again to force the packet
130 o If you send all packets immediately then it safe to send
131 any of subsequent packets through the queue, however, after
132 the first packet is put to queue then any subsequent packets
133 must also be put to the queue.
135 Follow these rules and everything works fine.
137 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Added new function silc_server_remove_clients_by_server to
140 remove all client entries from ID list when the server connection
141 is lost. In this case it is also important to invalidate all
142 client entires as they hold the invalid server entry. This
143 fixes fatal bug when server has lost connection and will reconnect
146 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Made some sanity checks to silc_server_daemonise like to check
149 whether the requested user and group actually exists.
151 * Added sanity check to SKE's silc_ske_responder_finish to check
152 that the public and private key actually is valid.
154 * Invalidate the client's nickname when receiving Replace ID
155 packet and the Client ID is being replaced. This means that the
156 server will query the nickname if someone needs it (client)
159 * Sort the ID Cache in client library when the ID Cache data
160 has changed (needs sorting).
162 * Do not allow for SILC client to create several connections to
163 several servers. The client does not support windows right now
164 and generating multiple connections causes weird behaviour.
166 Irssi-silc client does support windows and can handle several
167 connections without problems, see: www.irssi.org and SILC plugin.
169 * Fixed some places where client was added to the IDList. The
170 rule of thumb is following (in order to get everything right):
171 If the client is directly connected local client then the
172 `connection' argument must be set and `router' argument must be
173 NULL to silc_idlist_add_client function. If the client is not
174 directly connected client then the `router' argument must
175 bet set and the `connection' argument must be NULL to the
176 silc_idlist_add_client function.
178 * The funtion silc_server_packet_send_local_channel actually did
179 not check whether the client was locally connected or not. It
180 does that now. Fixed a bug related to LEAVE command.
182 * Fixed Remove Channel User payload parsing bug in server's
183 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
185 * The server's silc_server_save_channel_key now checks also the
186 global ID list for the channel as it might not be in the local
187 list. Fixed a bug related to LEAVE command.
189 * Is this the end of the [<unknown>] buglet that has been lurking
190 around for a long time? A little for loop fix in server's
191 silc_server_command_whois_parse that is used by both IDENTIFY
192 and WHOIS command. At least, this was a clear bug and a cause
193 of one type of [<unknown>] buglet.
195 * WHOIS and IDENTIFY commands call the function
196 silc_server_command_[whois/identify]_check function even if
197 we are not router server.
199 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Added --with-gmp configuration option. If set the GMP
202 is always compiled in the SILC source tree. If not set then
203 it is checked whether the system has the GMP3 installed. If
204 it has then the GMP won't be compiled (the system's headers
205 and library is used), if it doesn't have it then the GMP is
206 compiled in the SILC source tree.
208 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Changed RSA private exponent generation to what PKCS #1
211 suggests. We try to find the smallest possible d by doing
212 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
213 not security fix but optimization.
215 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Added new config entry [Identity] to fork the server and run
218 it as specific user and group. A patch from Bostik.
220 * Imported Dotconf configuration library into lib/dotconf.
221 This will be used to create the SILC configuration files later.
222 It will appear in the distsribution after this commit.
224 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * A big code auditing weekend happening. Auditing code for
227 obvious mistakes, bugs and errors. Also, removing any code
230 Removed files for being obsolete:
232 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
233 inline in the file lib/silcutil/silcbuffer.h)
235 o lib/silcutil/silcbufutil.c (the header has inline versions)
237 Changed code to fix possible error conditions:
239 o The buffer formatting routines now check that the destination
240 buffer really has enough space to add the data. This applies for
241 both buffer formatting and unformatting
242 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
243 unformatting was changed to accomodate following rules:
244 XXX_*STRING_ALLOC will allocate space for the data into the pointer
245 sent to the function while XXX_*STRING will not allocate or copy
246 the data into the buffer. Instead it sets the pointer from the
247 buffer into the pointer sent as argument (XXX_*STRING used to
248 require that the pointer must be allocated already). This change
249 makes this whole thing a bit more consistent and more optimized
250 (note that the data returned in the unformatting with XXX_*STRING
251 must not be freed now). The routines return now -1 on error.
253 o Tried to find all code that use buffer_format and buffer_unformat
254 and added return value checking to prevent formatting and
255 especially unformatting errors and possible subsequent fatal
258 o Changed ske->x and ske->KEY to mallocated pointers in
259 lib/silcske/silcske.h. Fixed possible data and memory leak.
261 o Added return value checking to all *_parse* functions. Fixed
262 many memory leaks as well.
264 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
265 so that buffer overflows would not happen. All code now also
266 checks the return value as it can fail.
268 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Added reconnection support to server if the normal server looses
271 its connection to the router (for example if router is rebooted).
272 The server performs normal reconnection strategy implemented
273 to the server. Affected file silcd/server.c.
275 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Added new packet type SILC_PACKET_SET_MODE that is used to
278 distribute the information about changed modes (for clients,
279 channels and clients channel modes) to all routers in the
280 network. Updated the protocol specification accordingly.
282 Added functions into silcd/packet_send.c and
283 silcd/packet_receive.c: silc_server_send_set_mode,
284 silc_server_set_mode.
286 Added new files silcmode.[ch] into lib/silccore that implements
287 the encoding and decoding of Set Mode Payload. Added new type
288 SilcSetModePayload. Moved the definitions of different modes
289 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
291 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Oops, a little mistake in server's connection authentication
294 protocol. The protocol is not ended with FAILURE but with
295 SUCCESS if the authentication is Ok. :) Affected file is
298 * Implemented NICK_CHANGE notify handling in server in the file
299 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
300 the local clients on the channel. After the changing nickname
301 in router environment snhould work and the [<unknown>] nickname
302 should appear no more.
304 The silc_server_replace_id function that receives the Replace ID
305 payload now sends the NICK_CHANGE notify type also in the file
306 silcd/packet_receive.c
308 * Changed WHOIS and IDENTIFY command to support the maximum amount
309 of arguments defined in protocol specs (3328 arguments). This
310 fixed a bug that caused problems when there were more than three
313 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Added extra parameter, command identifier, to the
316 silc_client_send_command so that explicit command identifier
319 Changed that ID list routines uses specific command identifier
320 when sending WHOIS/IDENTIFY requests to the server so that they
321 can be identified when the reply comes back.
323 Affected files lib/silcclient/command.[ch],
324 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
326 * Added `sender' argument to silc_server_packet_send_to_channel
327 to indicaet the sender who originally sent the packet to us
328 that we are now re-sending. Ignored if NULL. Affected file
329 silcd/packet_send.[ch].
331 * Added some server statistics support in silcd/server_internal.h
332 SilcServerStatistics structure and around the server code. Also
333 send some nice statistics information when client is connecting
336 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
338 * Fixed channel ID decoding in server's JOIN command reply in
339 silcd/command_reply.c
341 * Fixed braodcasting of replace ID payload to not to send it if
342 we are standalone server in silcd/packet_receive.c.
344 * Fixed all channel message sending routines to not to send
345 packets to clients that has router set, since they are routed
346 separately in the same function earlier. Affects file
347 silcd/packet_send.c and all channel packet sending functions.
349 * In USERS reply, res_argv[i] are not allocated, the table
350 is allocated. Thus changed that free the table, not its
353 * In server's whois_check and identify_check if the client is
354 locally connected do not send any WHOIS commands - they are not
357 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Fixed some minor bugs in client when sending WHOIS command. The
360 arguments was in wrong order.
362 * Removed statis function add_to_channel from server in
363 silcd/command.c that was previously used with the joining but
366 * Tested USERS command in router environment successfully with two
367 routers, two servers and two clients.
369 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Reorganized the USERS command and command reply in client library
372 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
373 When the command is given by user we register a pending command
374 callback that will reprocess the command after the reply has been
375 received from the server. When reprocessing the packet we then
376 display the information. Thus, the USERS information is displayed
377 now in the command callback instead of in the command reply
378 callback. The processing of the command is same as previously
379 when server has sent the command reply in the JOINing process.
381 * Added to USERS command in silcd/command_reply.c to join the client,
382 we didn't use to know about, to the channel after we've created
383 a client entry for it. Also, for clienet we did know already still
384 check whether it is on the channel or not and add it if not.
386 * Removed silc_server_command_join_notify as the function and its
389 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Changed the client's pending command handling to the same as the
392 server's pending command handling. It is also now possible to
393 execute command reply functions from other command reply
394 function as the function callbacks for commands and command
395 replies are one and same. The pending commands are not static
396 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
397 in client connection context. Thus, pending commands are server
398 connection specific as it is convenient.
400 Changed the function silc_client_command_pending and
401 silc_client_command_pending_del and added new function
402 silc_client_command_pending_check. Removed the
403 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
406 * Added cmd_ident, current command identifier, to the client
407 connection context in lib/silcclient/client.h to keep track on
408 command identifiers used in command sending. Client's command reply
409 function handling now supports the mandatory command identifiers.
411 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
412 funtions in client to fully support pending command callbacks.
414 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
415 as one of the arguments to the application in the command reply
418 * NOTE: The FORWARDED flag is depracated. It used to be depracated
419 before first releasing SILC but came back. Now it is removed again
420 and should come back nomore. The FORWARDED flag was used only
421 by the JOINing procedure by forwarding the command packet to router.
422 Now, the JOINing procedure has been changed to more generic (due
423 to various router environment issues) and FORWARDED is not needed
424 anymore for anything. The protocol specification is yet to be
427 Now, removed silc_server_packet_forward from server and the flag
428 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
430 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Renamed NAMES command to USERS command. The NAMES was named that
433 due to historical reasons. Now it is renamed. Also, rewrote
434 parts of the USERS command. The nickname list is not sent anymore
435 by the server. Only Client ID and mode lists are sent in the USERS
436 command. Changed this also to the protocol specification.
438 The client now resolves the names and stuff after it receives
439 the USERS list from the server when joining to the channel.
441 * WHOIS and IDENTIFY commands has been changed to support multiple
442 Client ID's per command. One can now search for multiple users
443 in the network by sending only one WHOIS or IDENTIFY command.
444 Changed the code and the protocol specifications.
446 * Removed silc_server_command_identify_parse and changed that IDENTIFY
447 uses silc_server_command_whois_parse to parse the request. */
449 * If normal server, do not parse the WHOIS and IDENTIFY requests
450 before sending it to the router. Saves some time.
452 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed JOIN command on client library. Wrong number of arguments
455 used to crash the client.
457 * Added silc_server_channel_has_global function to check whether
458 channel has global users or not.
460 * Added silc_server_channel_has_local function to check whether channel
461 has locally connected clients on the channel.
463 * The silc_server_remove_from_one_channel now checks whether the
464 channel has global users or not after given client was removed from
465 the channel. It also checks whether the channel has local clients
466 on the channel anymore. If it does not have then the channel entry
467 is removed as it is not needed anymore.
469 * The silc_server_notify now checks on JOIN notify whether the joining
470 client is one of locally connected or global. If it is global then
471 the channel has now global users on the channel and that is marked
472 to the channel entry. Also, it now saves the global client to
473 global list who is joining and JOINs it to the channel. This is
474 for normal server, that is.
476 Changed silc_server_send_notify_on_channel,
477 silc_server_packet_relay_to_channel and
478 silc_server_packet_send_to_channel check if we are normal server
479 and client has router set (ie. global client) do not send the
480 message to that client, as it is already routed to our router.
482 * Implemented LEAVE notify type handling in silc_server_notify
485 * Tested LEAVE command in router environment successfully. Tested
486 with two routers, two servers and two clients.
490 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
492 * Implemented SIGNOFF notify type handling in silc_server_notify
495 * silc_server_remove_id now removes the client entry from all channels
496 it has joined and thusly sends SIGNOFF notify type.
498 * Rewrote the NAMES list generation in server by removing two excess
499 loops. The lists are created now inside one loop.
501 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * silc_server_remove_channel_user checks now also global list
504 for channel and client.
506 * silc_server_new_channel_user checks now both local and global
507 list for channel and client. Fixed a bug in client id decoding.
508 Used to decode wrong buffer.
510 * silc_server_channel_message checks now both local and global
511 list for channel entry.
513 * Tested channel joining (hence JOIN) in router environment
514 successfully. Tested with two routers, two servers and two
517 * Tested channel message sending in router environment successfully.
519 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Added silc_server_save_channel_key into server.[ch] to save the
522 received channel key in Channel Key payload processing. It is
523 also used in JOIN command reply handling.
525 Equivalent function silc_client_save_channel_key added into
526 client.[ch] into client library.
528 * Changed JOIN command reply to send information whether the channel
529 was created or not (is existing already) and the channel key
530 payload. Changed protocol specs accordingly.
532 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
533 the request was sent by ID and not by nickname. Crashed on
536 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
539 now correctly save the received data.
541 * silc_server_free_sock_user_data now notifies routers in the
542 network about entities leaving the network.
544 At the same time implemented functions silc_server_remove_id
545 and silc_server_send_remove_id to receive and send REMOVE_ID
546 packets. The packet is used to notify routers in the network
547 about leaving entities. The ID removed will become invalid in
550 * Added function silc_idlist_del_server into server. Removes and
551 free's server entry from ID list.
553 * silc_server_private_message function now checks, if we are router,
554 that the destination ID really is valid ID, naturally.
556 * In router when NEW_ID packet is received (for new client) the
557 hash of the Client ID is saved in the ID Cache but the
558 client->nickname is set to NULL, instead of putting the hash
561 IDENTIFY command now also checks that client->nickname must be
562 valid. If it is not if will request the data from the server who
563 owns the client. Added new function
564 silc_server_command_identify_check.
566 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
567 to set the command to already allocated Command Payload.
569 * Tested private message sending in router environment with two
570 routers, two servers and two clients. Fixed minor bugs and now
573 * Fixed segfault from client's NAMES command. Used to crash if
576 * Forwarded packets must not be routed even if it is not destined
577 to the receiver. Changed server code comply with this.
579 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Added `require_reverse_mapping' boolean value to ServerParams
582 structure. If TRUE (not default) the server will require that
583 the connecting host has fully qualified domain name.
585 If the reverse mapping is not required and hostname could not be
586 found the IP address is used as hostname.
588 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Implemented version string checking to both client and server.
591 The check is incomplete currently due to the abnormal version
592 strings used in development version of SILC.
594 * Changed all command functions in server to use the new
597 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
599 * Changed char *data to unsigned char *data in ID Cache system to
600 support binary data as ID Cache data. Changed code to support
601 binary data in lib/silccore/idcache.c.
603 * Renamed silc_server_packet_relay_command_reply to
604 silc_server_command_reply as it is normal packet receiving
605 function. Rewrote the function to accept command replys for
606 servers and not only for clients.
608 * Mark remote router always as registered server if we are connecting
609 to it. Otherwise, commands sent by the router to us are ignored.
611 * All ID List find routines now returns the ID Cache Entry pointer
612 as well if requested.
614 * WHOIS command works now in router environment, tested with two
615 routers, two servers and two clients.
617 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
618 in router environment (as it is almost equivalent to WHOIS) but
619 hasn't been tested thoroughly. Added new functions:
621 silc_server_command_identify_parse
622 silc_server_command_identify_send_reply
623 silc_server_command_identify_from_client
624 silc_server_command_identify_from_server
626 * Disabled route cache adding because adding two different ID's with
627 same IP replaces the old cache entry thus giving wrong route.
628 The entry->router->connection is always the fastest route anyway
629 so route cache may not be needed. Of course, new routes maybe
630 established after receiving the ID when the entry->router->connection
631 might not be anymore the most optimal.
633 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * Add route cache for received ID for fast routing.
637 * Added silc_server_packet_route to route received packet on router
638 that is not destined to us.
640 * Renamed silc_server_get_route to silc_server_route_get.
642 * Added id_string and id_string_len fields into SilcServer to
643 include encoded ServerID for fast comparing without excess
644 encoding of the ID's.
646 * Cleaned up WHOIS command on server side. Added following static
649 silc_server_command_whois_parse
650 silc_server_command_whois_check
651 silc_server_command_whois_send_reply
652 silc_server_command_whois_from_client
653 silc_server_command_whois_from_server
655 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
656 arguments in command replies. All command functions should be
657 updated to use this macro.
659 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Minor typo fixes on command reply handling on server.
663 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Added silc_server_command_add_to_channel internal routine to add
666 the client to the channel after router has created the channel and
667 sent command reply to the server.
669 * Added generic silc_server_send_command to send any command from
672 * Use static buffer with ID rendering instead of duplicating data.
674 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Fixed a channel user mode bug when joining to a channel server gave
677 everybody channel founder rights, oops.
679 * We mark ourselves as the router of the incoming server connection
680 if we are router ourselves. This way we can check in some packet
681 sending functions whether it is locally connected server. For
682 incoming router connections we put NULL.
684 * For router sending packets locally means now always sending the
685 packet cell wide; to local clients and local servers. For normal
686 server sending packet locally means sending it to only local
689 * Fixed the JOIN command to really work in router environment. If the
690 channel is created it is always created by the router. Router is
691 also responsible of making the initial joining to the channel,
692 sending JOIN notify to the sending server and distributing
693 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
694 does not exist server doesn't do anything else but forward the
695 command to the router which performs everything.
697 * Added silc_server_send_channel_key function to send the Channel Key
700 * Added silc_server_create_channel_key to create new channel key. The
701 channel key is now re-generated everytime someone joins or leaves
702 a channel, as protocol dictates. Note: channel->key_len is the
705 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Splitted server.[ch] finally. Created now packet_send.[ch] and
708 packet_receive.[ch] to separate packet sending and receiving
709 routines. The server.[ch] now includes everything else including
710 actual packet processing (writing and reading data) and other
713 Renamed silc_server_private_message_send_internal to
714 silc_server_send_private_message. The routine is still though
715 used only to relay private messages as server does not send
716 private messages itself.
718 Renamed silc_server_new_channel to silc_server_create_new_channel
719 and added new function sicl_server_new_channel that handles the
720 incoming New Channel packet. Added also new sending function
721 silc_server_send_new_channel to send New Channel Payload.
723 * Added new function silc_server_notify to process incoming notify
724 packet to the server/router. Server may then relay the notify
725 to clients if needed.
727 * Added new function silc_server_new_channel_user to process incoming
728 New Channel User packet. Router will redistribute the packet and
729 send JOIN notify to its local clients and locally connected servers
730 if needed. Normal server will send JOIN notify to its local client
731 on same channel when received this packet. Added also corresponding
732 sending function silc_server_send_new_channel_user to sent the
735 * Added boolean route argument to send_notif_to_channel and
736 packet_send_to_channel functions to attempt to route the packet
737 if it is TRUE and send only locally if it is FALSE.
739 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * silc_server_replace_id now broadcasts the received replace ID
742 packet if it is not broadcast packet already. The router must
743 broadcast to inform other routers about changed ID.
745 * Added backpointer to server's router into SilcServer context in
746 silcd/server_internal.h.
748 * Fixed silc_server_packet_broadcast to send correct broadcast
751 * The channel key is now distributed to the local client as soon
752 as it is received from the router (in router environment) so that
753 no other packet may be sent for the channel until client has
756 * silc_server_remove_channel_user now broadcasts the received
757 Remove Channel User packet if it is not broadcast packet already.
758 The router must broadcast to inform other routers about removed
761 * Added users field into SilcPacketContext that is a reference count
762 of the context. One can increase the reference count by calling
763 silc_packet_context_dup which is now changed to just increase the
764 reference count instead of duplicating the data. The reference
765 count is decresed by calling silc_packet_context_free that will
766 free the data after the reference count hits zero.
768 For now on the packet context and everything allocated into it
769 (including the raw packet from network) must be freed by calling
770 the new silc_packet_context_free function. Added also new function
771 silc_packet_context_alloc that must be used now to allocate the
772 context. This also means that if a routine is asynchronous from
773 silc_[client/server]_packet_parse_type the packet context must
774 be duplicated by calling silc_packet_context_dup. Otherwise it
775 gets free'd after silc_[client/server]_packet_parse_type returns.
776 Also, one must remember that if packet is duplicated then its
777 reference count must be decresed by calling the free function as
778 many times as it was duplicated.
780 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
781 from both client and server.
783 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Made joining to a channel working in router environment.
787 * Cleaned up JOIN command on server side and create function
788 silc_server_command_join_channel internal routine to make the
791 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Changed silc_command_pending list to SilcDList. Also, added
794 `ident' field to SilcServerCommandPending structure to identify
795 the reply and to call correct callback.
797 Added silc_server_command_pending_check function to replace the
798 corresnponding macro. The silc_command_pending list is not
801 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
802 to set identifier to previously allocated Command Payload. It
803 is used to set identifier for command when resending Command
806 * Added silc_command_payload_encode_payload to encode Command
807 Payload buffer from SilcCommandPayload structure.
809 * Added silc_argument_payload_encode_payload to encode Argument
810 payload buffer from SilcArgumentPayload structure.
812 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Changed WHOIS command to support router connection on server side.
815 The whois request is always sent to router unless the server is
816 standalone server. After server has received the reply from the
817 router will it send the reply to the client.
819 * Added silc_server_packet_broadcast into silcd/server.[ch] to
820 broadcast received broadcast packet. The function is used only
821 by router. The broadcast packet is always sent to the router's
824 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
825 render given ID to printable string, for log files for example.
827 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Made basic router to router connections working. At least they
830 can now connect to each other but nothing really works the way
831 they are supposed - yet.
833 * Added new initiator token to RouterConnection configuration
834 file in silcd/serverconfig.[ch]. It is used to tell whether we
835 are the initiator to the remote router or whether we'll expect
836 the other end to connect.
838 * Moved registering of listener task to silc_server_init, hence
839 the server starts listenning as soon as it is run, even if it
840 does not have connections to other routers. Let's see how well
843 * Changed default connection retry timeouts for more suitable in
846 * Removed cipher and such arguments from silc_idlist_add_client
847 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
848 Added new function silc_idlist_add_data to add the keys and stuff
851 * Added SilcIDListData structure and added it to SilcClientEntry
852 and SilcServerEntry as their first field in the structure. This
853 way we can explicitly cast the ID entries to the SilcIDListData
854 structure and get common data for the entries. In past, we had
855 to first check what type of connection it is and then cast it to
856 correct ID entry type. Now, we can directly cast the opaque
857 pointer to the SilcIDListData (no matter what ID entry it actually
858 is) and get the data needed.
860 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Wow, found a bug in scheduler. The scheduler uninitialized itself
863 in some circumstances even if threre were timeout tasks, though not
864 IO tasks, but tasks anyway. Now fixed.
866 * Defined SilcServerConnection structure to hold connection specific
867 stuff about directly connected servers and routers. The definition
868 is currently in silcd/server_internal.h. I thought about having
869 a bit more important role fro this struct but for now it is used
870 only when connecting to other server (or router actually).
872 * Added connecting retry support in server when connecting to
873 router(s). The retry feature implement exponential backoff
874 algorithm. Also, added SilcServerParams structure to hold default
875 parameters for server. For now, it include these retry settings
876 and are hard coded. After server is moded to be as Silc Server
877 Library this structure will be more important.
879 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Changed client librarys channel->clients table to SilcList and
882 changed code accordingly.
884 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Changed client's channel table to SilcList and changed code
887 accordingly. Also changed SilcChannelClientEntry to include back-
888 pointer to the channel so that client entry can use that structure
889 as list as well and we have fast cross-reference to the channel.
890 This change dramatically decreased the complexity of channel
891 handling with client entry and vice versa (removed one extra
892 loop when searching for channel entry from many functions).
894 * Changed server->sim from table to SilcDList and changed code
897 * NAMES command can now be used from user interface. It will show
898 the user list on the channel, neatly.
900 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
901 Code now saves realname of the user if it becomes available.
903 * Renamed configure.in to configure.in.pre and made ./prepare
904 script to automatically add correct version string to
905 configure.in which it creates from configure.in.pre.
907 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * NAMES command reply now shows users mode with the nickname when
912 * Moved silc_client_ch[u]mode[_char] functions from
913 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
914 place sucks, they are utility functions and should be in some
917 * Fixed some unsigned int's to unsigned short's. Patch by cras.
919 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
922 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added TRQ (efficient deque and list library) into lib/trq. This is
927 a very good list library that is currently used in the SILC. Defined
928 SilcList API over the library because I didn't like the API very
929 much. See lib/trq/silclist.h for the API and examples of how to
930 use the API. Fixed various places in the code to use the new
931 SilcList API. The SilcList is meant for lists that has a structure
932 already defined as a list. It is not suitable to add just some
933 context to the list (in TRQ, the context is the list actually).
935 So, I defined SilcDList that can be used for the purpose where
936 predefined list structure does not exit. This can be used as
937 such list. Now some context just can be added to the SilcDList.
938 Currently this list is not used in the SILC just yet, though there
939 are a lot places where this can replace dynamically allocated
940 tables and I will fix these places, later, to use SilcDList.
941 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
942 and use TRQ internally).
944 Also fixed some annoying warning messages that the original TRQ
945 code generated. Also minor changes to TRQ's Makefile.in.
947 * Added support for querying by Client ID to both WHOIS and
948 IDENTIFY commands into server, as required by the protocol.
950 * Removed method function pointers from SilcBuffer structure. They
951 weren't used to anything and just increased the context size for
952 no good reason. This change also made silc_buffer_alloc and
953 silc_buffer_free functions inline functions.
955 * Disabled command flooding detection support until it's fixed so
956 that it accepts commands in but does not execute them more than once
959 * Added silc_net_localhost(), to return local hostname, into
960 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
961 that must be initialized before calling silc_client_init.
963 * Added new function: silc_server_send_notify_on_channels to send
964 notify messages to all channels client has joined. It is assured
965 that the message is sent only once per client.
967 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
968 lib/silcutil/silcutil.[ch] as silc_format function. The new
969 function is generic and is used by server as well, not only by
970 the logging routines.
972 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
973 the provided version string was not acceptable. Added new function:
974 silc_ske_check_version into lib/silcske/silcske.h. The function
975 must be implemented by the application (client or server) and it
976 does not reside in the SKE library. The function checks the version
977 string remote end sent.
979 * Added back pointers (to opaque context and to SilcSocketConnection)
980 into SilcPacketContext structure into lib/silccore/silcpacket.h.
982 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
983 duplicate packet context structure.
985 * Changed `notify' client operation to send same arguments as client
986 receives from server except for ID's. ID's are mapped to correct
987 ID entry and that is returned. Also, if channel entry is not sent
988 by server but the notify is for channel the channel entry is sent
989 to application (otherwise application doesn't know that it is for
990 channel (library gets it from packet's Destination ID)).
992 * Added silc_client_remove_from_channels into client library to
993 remove a client from all channels it has joined to. Used when
994 received SIGNOFF notify from server. Added also new function
995 silc_client_replace_from_channels to replace old ID entry with
996 new ID entry on all channels. Used when received NICK_CHANGE
999 * Fixed ID Cache list handling in silc_idlist_get_client in
1000 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1001 to get (or query) client by ID.
1003 * Updated TODO list.
1005 * Added connection authentication status message defined by the
1006 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1007 support for these into the code in client and server side.
1009 * Added generic function silc_client_send_command to send any command
1010 with variable argument list. Application should use this function
1011 to send commands if the command functions provided by the library
1012 does not suite for the application's user interface needs.
1014 * Added new `failure' client operation. Application is notified about
1015 received failure packet if client is executing a protocol. In this
1016 case the protocol's execution has failed.
1018 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1019 is required by the protocol.
1021 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1022 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1025 * Added status flag to SilcSKE object to indicate realtime status
1026 of the SKE protocol.
1028 * Application receives now exactly same command reply arguments as
1029 the library receives from server. However, if ID is received the
1030 corresponding ID entry is returned to the application (eg. Client
1031 ID is mapped to correct SilcClientEntry entry and that is returned).
1032 Changed command_reply client operation due to this change.
1034 * Changed all ID's in commands and in command replys as ID Payloads.
1035 Change affected both client and server side codes.
1037 All ID's sent in SILC network (with execption of ID's in SILC
1038 Packet header) are sent in ID Payload to support variable length
1041 * Server now notifies nick changes and notifies all clients on
1042 the channels about the new nickname (about the new Client ID,
1045 * Implemented CMODE command to change channel modes. Supports all
1046 channel modes defined by the protocol specs except ban and invite
1047 lists. (Also, private channel key mode is supported but support for
1048 setting private channel key in client is missing, thus, this mode
1049 has no effect on client side (except that server requires that the
1050 client uses private channel key and normal channel traffic does not
1053 Also, invite mode works per se, but INVITE command does not work
1054 yet correctly, so you can set channel as invite only channel but
1055 inviting clients to the channel does not work (it is yet to be
1056 thought what's the best way to do it).
1058 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1059 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1060 Implemented CUMODE command to change user's mode on the channel.
1061 Supports all modes defined by the protocol specs.
1063 * Added NAMES command reply to return users modes on the channel.
1065 * Removed unnecessary and slow ciphers from lib/silccrypt.
1067 * Set SO_KEEPALIVE option to connection sockets by default.
1069 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1071 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1072 redefined the Notify Payload into protocol specs.
1074 * Added silc_id_payload_parse_id to get ID directly from raw
1077 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1080 accept searching by Client ID as well.
1082 * Added support for LEAVE and SIGNOFF notify types in client library.
1084 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1085 to parse ID Payload from raw data.
1087 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Added flags parameter into silc_ske_assemble_security_properties
1090 function in lib/silcske/silcske.[ch].
1092 * Changed notify client operation to fit better for notify messages
1093 sent by server. The notify payload received from server is now
1094 passed to the application (after parsing it to SilcNotifyPayload).
1095 It is application's responsibility to retrieve the arguments
1096 from the payload and show the message the way it wants. The message
1097 sent by server is implementation specific.
1099 * Changed public keys to comply with the protocol specification.
1100 Old public keys are not supported anymore and are not compatible.
1102 * Removed nickname from Channel Payload as the latest draft removed
1103 it. The client must resolve the nickname from the NAMES command
1104 reply received when it joined the channel.
1106 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1108 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Fixed some errors in protocol specification drafts.
1112 * Created lib/silccore/silcnotify.c to implement Notify Payload
1113 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1114 generic payloads described by protocol specifications. The file
1115 includes implementations for ID Payload and Argument Payload.
1117 * Changed Command Payload implementation to use the new Argument
1118 Payload. Changed command_xxxx_payload to command_payload_xxxx
1119 to comply with SILC coding conventions.
1121 * Added suppport for Argument Payload handling in Notify Payload
1122 implementation as protocol requires it. Added the new support
1123 into server and client lib as well.
1125 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Added support for multiple nicknames on same channel. [n] is
1128 added locally to the nickname if there are more than one same
1129 nicknames on the channel.
1131 * Server now sends all nicknames that matched WHOIS request.
1132 Client also shows the list received from server.
1134 * Added TOPIC command to client side. User can now set and show
1135 current topic on channel.
1137 * Added MOTD command to client and server. Also, server sends the
1138 motd when client connects to the server.
1140 * Changed version strings to comply ISO 8601.
1142 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Fixed protocol error handling in client library. It should now
1145 cope even if the SKE fails for some reason.
1147 * Made new protocol specification drafts for submitting to IETF.
1149 * Implemented TOPIC command to server in silcd/command.c.
1151 * Added two new notify types into lib/silccore/silcnotify.h:
1152 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1153 notify nickname change and topic setting/change on a channel.
1155 * API change of command_reply operation in client library. The
1156 application gets now the status type received from server as well.
1158 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1162 * Cras fixed and optimized the packet handling even further and
1163 it should work now. Minor change to the prototype of function
1164 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1166 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Added new function into lib/silcutil/silcschedule.[ch]:
1169 silc_schedule_with_fd to select() a specified fd. The function
1170 returns after timeout expires or data arrives or goes. The
1171 function is used by packet routines to wait that all data is
1172 received from network.
1174 * Fixed data reading from network in lib/silccore/silcpacket.c.
1175 The code now assures that all data is read from the fd and then
1176 continues packet processing. This was a bug fix since the code
1177 used to drop some data in some circumstances.
1179 * Added new function into lib/silcclient/client.[ch]:
1180 silc_client_start_key_exchange to start key exchange after
1181 connection has been established to server. The code internally
1182 now uses this funtion but its main purpose was to provide it
1183 for applications that perform their own connecting. After
1184 application has created a connection it merely calls this
1185 function to start the key exchange between client and server.
1186 The library takes care of everything else after that.
1188 Updated also lib/silcclient/README to explain the usage of
1191 * Do not send to application information that connection has
1192 been established. Application gets notified it by connect
1195 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Applied cras's patch to add silc_schedule_one function. The
1198 function runs scheduler once and returns.
1200 * Fixed the scheduler after cras messed it up. The timeout
1201 handling works now as it's supposed to work.
1203 * Added into lib/silccore/ silcnotify.h to include notify
1204 message types support. Changed silc_server_send_notify*
1205 functions, in server.[ch], to support those new notify types.
1206 Added the support for the notify types into client library,
1207 as well. Added new notify client operation into ops.h in
1210 * Changed silc_server_packet_send_to_channel to send normal
1211 packets instead of just channel message packets. The function
1212 is now used to send the notify packets to channels. It is not
1213 used to send channel message packets anymore, as server never
1216 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1217 va_arg()s as it seems to require it nowadays. I guess, if SILC
1218 is compiled with older va_arg() the new code should work anyway.
1220 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * Splitted core library. Core library (lib/silccore) includes
1223 now only SILC protocol specific core (and common) components.
1224 Created new utility library (lib/silcutil) that includes more
1225 generic purpose stuff. The stuff for util library was taken
1226 from the old core library. This was minor and easy split.
1228 * Created SILC Client Library (lib/silcclient) that includes
1229 implementation of the SILC client without user interface. This
1230 was major move from silc/ directory. The code has been changed
1231 so that it is transparent towards the user interface. The
1232 silc/ directory includes now the same user interface as before
1233 and it uses the new client library. Read lib/silcclient/README.
1234 Basicly, the client library performs everything else related
1235 to SILC except user interface handling. Also, configuration
1236 files are considered to be part of user interface and library
1237 does not handle them.
1239 This change also changed a lot of structures, function naming etc.
1240 Most important change was that SilcClientWindow object was
1241 renamed to SilcClientConnection in the client library. Created
1242 also new file lib/silcclient/ops.h. Also added new files
1243 silc/local_command.[ch] and silc/client_ops.[ch].
1245 All these changes were made to make it easier for user interface
1246 designers to create what ever user interface for the SILC client
1249 It is also expected that the server will be moved to lib
1250 directory as well and SILC Server Library will be created;
1251 sometimes in the future.
1253 * Removed Local commands from lib/silccore/silccommand.h as
1254 they are application specific and new client library does not
1255 handle any of those anymore.
1257 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1258 old client implementation in silc/.
1260 * Added support for callback functions in SILC_LOG_* macros.
1261 Application can now set its own callbacks that will be called
1262 instead of using the default functions that will always print
1263 the debug messages to stderr (or stdout). Also, debugging can
1264 now be disabled by setting silc_debug to FALSE and re-enabled by
1265 setting it to TRUE. Note, that logging will still work even
1266 if debugging is disabled.
1268 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1269 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1270 silc_log_reset_debug_callbacks.
1272 * To enable debugging in silc client one must give now -d
1273 option on command line.
1275 * Changed silc_schedule_init to automatically allocate task queues
1276 if they are not allocated before calling it.
1278 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Added GMP 3.1 into math library.
1282 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1285 a channel in SILC network. The packet is used by servers and
1286 routers to notify other routers that user has left a channel.
1287 This little feature was missing until now. Added the feature
1288 to protocol specification as well.
1290 Added functions: silc_server_send_remove_channel_user and
1291 silc_server_remove_channel_user into server.[ch].
1293 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1294 lib/silccore/silcpacket.h. However, they are not implemented
1297 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1299 * Fixed joining to a channel and sending channel messages
1300 between server and router. The channel message sending should
1301 now work inside a cell.
1303 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Fixed the private message sending between server and router.
1306 The private message sending should now work inside a cell.
1308 * Added silc_server_replace_id into server.[ch] to replace
1309 existing ID in the SILC network.
1311 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1312 and silc_idlist_replace_server_id into idlist.[ch] in server.
1314 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Fixed the server to server connections. Server can again now
1317 connect to router. Router to router connections probably does
1320 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Added dynamic protocol registering support. Now protocols can
1323 registered and unregistered on the fly. Patch by cras.
1325 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Added lib/contrib directory to hold routines that some platforms
1328 don't have but are needed by SILC.
1330 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1331 into lin/contrib to provide getopt() and getopt_long() for
1332 those who don't have it.
1334 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Added AWAY command to client. When away message is set and
1337 client receives a private message packet the client automatically
1338 replies to the sender with the away message.
1340 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1341 bug seemed to be the cause of recent problems when compiling
1344 * Added version detection support to SKE protocol specification
1345 and added the new changes to the SKE implementation as well.
1346 There were other minor changes in the SKE protocol as well.
1348 Many changes in lib/silcske/silcske.[ch] and in
1349 lib/silcske/payload.[ch].
1351 * Added ^U functionality, clear input line. Patch from cras.
1353 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Mainly small bugfixes on core library. Fixed some debugging
1356 logging and buffer overflow in silclog.c.
1358 * Updated config.sub and config.guess on the distribution tree.
1360 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Added command lagging support in server. Client may execute
1363 commands now only once in two seconds.
1365 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Optimized packet reception. MAC computation and checking is now
1368 also more optimized. A lot previously duplicated code is now
1369 used as generic by both client and server.
1371 * Fixed key pair generation in clientutil.c
1373 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Added into lib/silccore/silcbufutil.[ch] new function;
1376 silc_buffer_realloc.
1378 * Moved generic packet sending/encryption functions to
1379 lib/silccore/silcpacket.[ch] from client and server. Some
1380 rewriting of the functions.
1382 * Moved all generic packet reception/decryption functions to
1383 lib/silccore/silcpacket.[ch] from client and server. The
1384 packet processing is now much cleaner in both client and server.
1385 These were major changes in both client and server.
1387 * Created many common functions in server to do packet sending.
1388 Previously code were duplicated a lot, this has been removed
1391 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Rewrote major parts of the ID cache system. Don't know
1394 whether it is better now or not but at least the API is more
1397 * Major rewrite on ID cache stuff on client because of the ID
1398 cache API changes. Added idlist.c to client.
1400 * Also major rewrite on ID cache stuff on server as well.
1401 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1402 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1403 in hand, instead they are all put into the ID cache system now.
1404 All server_idlist_* routines uses ID cache now instead of
1405 traversing its own lists (those lists does not exist anymore).
1406 SilcIDList though still exists. Also, SilcXXXEntry's are
1409 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * Finally made the SKE implementation compliant to the protocol
1412 specification. All mp integers are now binary encoded as
1413 opposed being HEX encoded.
1415 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1418 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1419 functions: silc_[encode/decode]_pem. Also added function
1420 silc_encode_pem_file to PEM encode with newlines ('\n') for
1423 * SILC public keys are now encoded either PEM or binary. Same
1424 option is for private keys as well. By default private keys
1425 are binary encoded and public keys PEM encoded. Silly HEX
1426 encoding were removed.
1428 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1429 function to create fingerprints.
1431 * Fixed a bug in SHA1; does not change the original data anymore.
1433 * Partly implemented INFO command on client and server side.
1434 Fixed CLEAR command. Changes to SERVER command; show current
1435 server(s) when giving command without arguments. Added
1436 VERSION command to client.
1438 * Added check to server that unregistered connections cannot
1439 execute commands (unless it is specificly allowed).
1441 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed screen refresh.
1445 * Fixed channel joining bug from client. On some circumstances
1446 client tried to join to a channel it had already joined.
1448 * Added public key verification process into client's protocol.c.
1449 The client now verifies the public key from user and saves
1450 it into ~./silc/serverkeys/ directory.
1452 Added into: clientutil.[ch]: silc_client_verify_server_key.
1454 * Changed SKE protocol's silc_ske_initiator_finish function
1455 to accept callback function that verifies the received public
1456 key. Removed old silc_ske_verify_public_key function.
1458 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1461 silc_pkcs_private_key[_data]_set.
1463 * Made the password and public authentication more cleaner in
1464 server's protocol.c.
1466 * Removed historic and obsolete protocol `channel_auth' from
1467 both client and server.
1469 * Removed wrong way of sending command status messages from
1470 server to client in server's command.c. The old way violated
1471 protocol specification.
1473 Changes to silccore/silccommand.[ch]: removed
1474 silc_command_encode_status_payload -> not needed anymore,
1475 changed silc_command_encode_payload_va to accept extra
1476 argument on variable argument list. The argument type must
1477 now be provided to the function. Also, added new function:
1478 silc_command_encode_reply_payload_va which is same as
1479 normal command_encode_payload_va except command status type
1480 is provided as extra argument.
1482 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Added ~./silc directory handling. The directory includes the
1485 public and private keys for the client.
1487 Added silc_client_check_silc_dir, silc_client_create_identifier
1488 and silc_client_load_keys.
1490 * Implemented SILC protocol compliant public key. Added public
1491 and private key saving to and loading from files.
1493 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1494 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1495 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1496 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1497 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1499 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1500 silc_pkcs_load_[public/private]_key.
1502 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1504 * Added silc_server_get_route (route.[ch]) to get connection
1505 data for the fastest route for given ID.
1507 * Implemented INVITE command on client and server. The command
1508 were re-defined in the SILC Protocol Specification and the
1509 implementation now complies with the specification.
1511 * Implemented PING command on client and server.
1513 * Implemented NAMES command on client and server. The server side
1514 supports currently only normal server not router server yet.
1515 Some changes to NAMES definition in SILC protocol specification.
1517 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Implemented LEAVE command on client and server.
1521 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1522 again. This change was made to the protocol as well. Server
1523 should not violate the protocol specification anymore.
1525 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1528 was tested. SOCKS4 was not but should work anyway.
