3 * Call silc_server_command_identify_check always when processing
4 the IDENTIFY command in silcd/command.c
6 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
9 send keepalive packets. The packet can be sent by clients,
12 Added function silc_socket_set_heartbeat into the file
13 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
14 If not set, the heartbeat is not performed. The actual
15 heartbeat is implemented in the low level socket connection
16 library. However, application is responsible of actually
19 Added silc_server_send_heartbeat to send the actual heartbeat
20 packet into silcd/packet_send.[ch]. Server now performs
21 keepalive with all connections.
23 * Added silc_task_get_first function into lib/silcutil/silctask.c
24 to return the timeout task with shortest timeout. There was a bug
25 in task unregistration that caused problems. TODO has been
26 updated to include that task system must be rewritten.
28 * The client library will now resolve the client information when
29 receiving JOIN notify from server for client that we know but
30 have incomplete information.
32 * Rewrote parts of silc_server_remove_from_channels and
33 silc_server_remove_from_one_channel as they did not remove the
34 channel in some circumstances even though they should've.
36 * Encryption problem encountered in server:
38 The LEAVE command used to send the Channel Key packet to the
39 router immediately after generating it. However, the code
40 had earlier sent Remove Channel user packet but not immediately,
41 ie. it was put to queue. The order of packets in the router
42 was that Channel Key packet was first and Remove Channel User
43 packet was second, even though they were encrypted in the
44 reverse order. For this reason, MAC check failed. Now, this
45 is fixed by not sending the Channel Key packet immediately but
46 putting it to queue. However, this is more fundamental problem:
47 packets that are in queue should actually not be encrypted
48 because packets that are sent immediately gets encrypted
49 actually with wrong IV (and thus MAC check fails). So, packets
50 that are in queue should be encrypted when they are sent to
51 the wire and not when they put to the queue.
53 However, the problem is that the current system has not been
54 designed to work that way. Instead, the packet is encrypted
55 as soon as possible and left to the queue. The queue is then
56 just purged into wire. There won't be any fixes for this
57 any time soon. So, the current semantic for packet sending
60 o If you send packet to remote host and do not force the send
61 (the packet will be in queue) then all subsequent packets to the
62 same remote host must also be put to the queue. Only after the
63 queue has been purged is it safe again to force the packet
66 o If you send all packets immediately then it safe to send
67 any of subsequent packets through the queue, however, after
68 the first packet is put to queue then any subsequent packets
69 must also be put to the queue.
71 Follow these rules and everything works fine.
73 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
75 * Added new function silc_server_remove_clients_by_server to
76 remove all client entries from ID list when the server connection
77 is lost. In this case it is also important to invalidate all
78 client entires as they hold the invalid server entry. This
79 fixes fatal bug when server has lost connection and will reconnect
82 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
84 * Made some sanity checks to silc_server_daemonise like to check
85 whether the requested user and group actually exists.
87 * Added sanity check to SKE's silc_ske_responder_finish to check
88 that the public and private key actually is valid.
90 * Invalidate the client's nickname when receiving Replace ID
91 packet and the Client ID is being replaced. This means that the
92 server will query the nickname if someone needs it (client)
95 * Sort the ID Cache in client library when the ID Cache data
96 has changed (needs sorting).
98 * Do not allow for SILC client to create several connections to
99 several servers. The client does not support windows right now
100 and generating multiple connections causes weird behaviour.
102 Irssi-silc client does support windows and can handle several
103 connections without problems, see: www.irssi.org and SILC plugin.
105 * Fixed some places where client was added to the IDList. The
106 rule of thumb is following (in order to get everything right):
107 If the client is directly connected local client then the
108 `connection' argument must be set and `router' argument must be
109 NULL to silc_idlist_add_client function. If the client is not
110 directly connected client then the `router' argument must
111 bet set and the `connection' argument must be NULL to the
112 silc_idlist_add_client function.
114 * The funtion silc_server_packet_send_local_channel actually did
115 not check whether the client was locally connected or not. It
116 does that now. Fixed a bug related to LEAVE command.
118 * Fixed Remove Channel User payload parsing bug in server's
119 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
121 * The server's silc_server_save_channel_key now checks also the
122 global ID list for the channel as it might not be in the local
123 list. Fixed a bug related to LEAVE command.
125 * Is this the end of the [<unknown>] buglet that has been lurking
126 around for a long time? A little for loop fix in server's
127 silc_server_command_whois_parse that is used by both IDENTIFY
128 and WHOIS command. At least, this was a clear bug and a cause
129 of one type of [<unknown>] buglet.
131 * WHOIS and IDENTIFY commands call the function
132 silc_server_command_[whois/identify]_check function even if
133 we are not router server.
135 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
137 * Added --with-gmp configuration option. If set the GMP
138 is always compiled in the SILC source tree. If not set then
139 it is checked whether the system has the GMP3 installed. If
140 it has then the GMP won't be compiled (the system's headers
141 and library is used), if it doesn't have it then the GMP is
142 compiled in the SILC source tree.
144 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Changed RSA private exponent generation to what PKCS #1
147 suggests. We try to find the smallest possible d by doing
148 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
149 not security fix but optimization.
151 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Added new config entry [Identity] to fork the server and run
154 it as specific user and group. A patch from Bostik.
156 * Imported Dotconf configuration library into lib/dotconf.
157 This will be used to create the SILC configuration files later.
158 It will appear in the distsribution after this commit.
160 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * A big code auditing weekend happening. Auditing code for
163 obvious mistakes, bugs and errors. Also, removing any code
166 Removed files for being obsolete:
168 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
169 inline in the file lib/silcutil/silcbuffer.h)
171 o lib/silcutil/silcbufutil.c (the header has inline versions)
173 Changed code to fix possible error conditions:
175 o The buffer formatting routines now check that the destination
176 buffer really has enough space to add the data. This applies for
177 both buffer formatting and unformatting
178 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
179 unformatting was changed to accomodate following rules:
180 XXX_*STRING_ALLOC will allocate space for the data into the pointer
181 sent to the function while XXX_*STRING will not allocate or copy
182 the data into the buffer. Instead it sets the pointer from the
183 buffer into the pointer sent as argument (XXX_*STRING used to
184 require that the pointer must be allocated already). This change
185 makes this whole thing a bit more consistent and more optimized
186 (note that the data returned in the unformatting with XXX_*STRING
187 must not be freed now). The routines return now -1 on error.
189 o Tried to find all code that use buffer_format and buffer_unformat
190 and added return value checking to prevent formatting and
191 especially unformatting errors and possible subsequent fatal
194 o Changed ske->x and ske->KEY to mallocated pointers in
195 lib/silcske/silcske.h. Fixed possible data and memory leak.
197 o Added return value checking to all *_parse* functions. Fixed
198 many memory leaks as well.
200 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
201 so that buffer overflows would not happen. All code now also
202 checks the return value as it can fail.
204 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Added reconnection support to server if the normal server looses
207 its connection to the router (for example if router is rebooted).
208 The server performs normal reconnection strategy implemented
209 to the server. Affected file silcd/server.c.
211 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Added new packet type SILC_PACKET_SET_MODE that is used to
214 distribute the information about changed modes (for clients,
215 channels and clients channel modes) to all routers in the
216 network. Updated the protocol specification accordingly.
218 Added functions into silcd/packet_send.c and
219 silcd/packet_receive.c: silc_server_send_set_mode,
220 silc_server_set_mode.
222 Added new files silcmode.[ch] into lib/silccore that implements
223 the encoding and decoding of Set Mode Payload. Added new type
224 SilcSetModePayload. Moved the definitions of different modes
225 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
227 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Oops, a little mistake in server's connection authentication
230 protocol. The protocol is not ended with FAILURE but with
231 SUCCESS if the authentication is Ok. :) Affected file is
234 * Implemented NICK_CHANGE notify handling in server in the file
235 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
236 the local clients on the channel. After the changing nickname
237 in router environment snhould work and the [<unknown>] nickname
238 should appear no more.
240 The silc_server_replace_id function that receives the Replace ID
241 payload now sends the NICK_CHANGE notify type also in the file
242 silcd/packet_receive.c
244 * Changed WHOIS and IDENTIFY command to support the maximum amount
245 of arguments defined in protocol specs (3328 arguments). This
246 fixed a bug that caused problems when there were more than three
249 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Added extra parameter, command identifier, to the
252 silc_client_send_command so that explicit command identifier
255 Changed that ID list routines uses specific command identifier
256 when sending WHOIS/IDENTIFY requests to the server so that they
257 can be identified when the reply comes back.
259 Affected files lib/silcclient/command.[ch],
260 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
262 * Added `sender' argument to silc_server_packet_send_to_channel
263 to indicaet the sender who originally sent the packet to us
264 that we are now re-sending. Ignored if NULL. Affected file
265 silcd/packet_send.[ch].
267 * Added some server statistics support in silcd/server_internal.h
268 SilcServerStatistics structure and around the server code. Also
269 send some nice statistics information when client is connecting
272 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Fixed channel ID decoding in server's JOIN command reply in
275 silcd/command_reply.c
277 * Fixed braodcasting of replace ID payload to not to send it if
278 we are standalone server in silcd/packet_receive.c.
280 * Fixed all channel message sending routines to not to send
281 packets to clients that has router set, since they are routed
282 separately in the same function earlier. Affects file
283 silcd/packet_send.c and all channel packet sending functions.
285 * In USERS reply, res_argv[i] are not allocated, the table
286 is allocated. Thus changed that free the table, not its
289 * In server's whois_check and identify_check if the client is
290 locally connected do not send any WHOIS commands - they are not
293 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Fixed some minor bugs in client when sending WHOIS command. The
296 arguments was in wrong order.
298 * Removed statis function add_to_channel from server in
299 silcd/command.c that was previously used with the joining but
302 * Tested USERS command in router environment successfully with two
303 routers, two servers and two clients.
305 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Reorganized the USERS command and command reply in client library
308 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
309 When the command is given by user we register a pending command
310 callback that will reprocess the command after the reply has been
311 received from the server. When reprocessing the packet we then
312 display the information. Thus, the USERS information is displayed
313 now in the command callback instead of in the command reply
314 callback. The processing of the command is same as previously
315 when server has sent the command reply in the JOINing process.
317 * Added to USERS command in silcd/command_reply.c to join the client,
318 we didn't use to know about, to the channel after we've created
319 a client entry for it. Also, for clienet we did know already still
320 check whether it is on the channel or not and add it if not.
322 * Removed silc_server_command_join_notify as the function and its
325 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Changed the client's pending command handling to the same as the
328 server's pending command handling. It is also now possible to
329 execute command reply functions from other command reply
330 function as the function callbacks for commands and command
331 replies are one and same. The pending commands are not static
332 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
333 in client connection context. Thus, pending commands are server
334 connection specific as it is convenient.
336 Changed the function silc_client_command_pending and
337 silc_client_command_pending_del and added new function
338 silc_client_command_pending_check. Removed the
339 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
342 * Added cmd_ident, current command identifier, to the client
343 connection context in lib/silcclient/client.h to keep track on
344 command identifiers used in command sending. Client's command reply
345 function handling now supports the mandatory command identifiers.
347 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
348 funtions in client to fully support pending command callbacks.
350 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
351 as one of the arguments to the application in the command reply
354 * NOTE: The FORWARDED flag is depracated. It used to be depracated
355 before first releasing SILC but came back. Now it is removed again
356 and should come back nomore. The FORWARDED flag was used only
357 by the JOINing procedure by forwarding the command packet to router.
358 Now, the JOINing procedure has been changed to more generic (due
359 to various router environment issues) and FORWARDED is not needed
360 anymore for anything. The protocol specification is yet to be
363 Now, removed silc_server_packet_forward from server and the flag
364 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
366 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Renamed NAMES command to USERS command. The NAMES was named that
369 due to historical reasons. Now it is renamed. Also, rewrote
370 parts of the USERS command. The nickname list is not sent anymore
371 by the server. Only Client ID and mode lists are sent in the USERS
372 command. Changed this also to the protocol specification.
374 The client now resolves the names and stuff after it receives
375 the USERS list from the server when joining to the channel.
377 * WHOIS and IDENTIFY commands has been changed to support multiple
378 Client ID's per command. One can now search for multiple users
379 in the network by sending only one WHOIS or IDENTIFY command.
380 Changed the code and the protocol specifications.
382 * Removed silc_server_command_identify_parse and changed that IDENTIFY
383 uses silc_server_command_whois_parse to parse the request. */
385 * If normal server, do not parse the WHOIS and IDENTIFY requests
386 before sending it to the router. Saves some time.
388 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Fixed JOIN command on client library. Wrong number of arguments
391 used to crash the client.
393 * Added silc_server_channel_has_global function to check whether
394 channel has global users or not.
396 * Added silc_server_channel_has_local function to check whether channel
397 has locally connected clients on the channel.
399 * The silc_server_remove_from_one_channel now checks whether the
400 channel has global users or not after given client was removed from
401 the channel. It also checks whether the channel has local clients
402 on the channel anymore. If it does not have then the channel entry
403 is removed as it is not needed anymore.
405 * The silc_server_notify now checks on JOIN notify whether the joining
406 client is one of locally connected or global. If it is global then
407 the channel has now global users on the channel and that is marked
408 to the channel entry. Also, it now saves the global client to
409 global list who is joining and JOINs it to the channel. This is
410 for normal server, that is.
412 Changed silc_server_send_notify_on_channel,
413 silc_server_packet_relay_to_channel and
414 silc_server_packet_send_to_channel check if we are normal server
415 and client has router set (ie. global client) do not send the
416 message to that client, as it is already routed to our router.
418 * Implemented LEAVE notify type handling in silc_server_notify
421 * Tested LEAVE command in router environment successfully. Tested
422 with two routers, two servers and two clients.
426 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
428 * Implemented SIGNOFF notify type handling in silc_server_notify
431 * silc_server_remove_id now removes the client entry from all channels
432 it has joined and thusly sends SIGNOFF notify type.
434 * Rewrote the NAMES list generation in server by removing two excess
435 loops. The lists are created now inside one loop.
437 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * silc_server_remove_channel_user checks now also global list
440 for channel and client.
442 * silc_server_new_channel_user checks now both local and global
443 list for channel and client. Fixed a bug in client id decoding.
444 Used to decode wrong buffer.
446 * silc_server_channel_message checks now both local and global
447 list for channel entry.
449 * Tested channel joining (hence JOIN) in router environment
450 successfully. Tested with two routers, two servers and two
453 * Tested channel message sending in router environment successfully.
455 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
457 * Added silc_server_save_channel_key into server.[ch] to save the
458 received channel key in Channel Key payload processing. It is
459 also used in JOIN command reply handling.
461 Equivalent function silc_client_save_channel_key added into
462 client.[ch] into client library.
464 * Changed JOIN command reply to send information whether the channel
465 was created or not (is existing already) and the channel key
466 payload. Changed protocol specs accordingly.
468 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
469 the request was sent by ID and not by nickname. Crashed on
472 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
475 now correctly save the received data.
477 * silc_server_free_sock_user_data now notifies routers in the
478 network about entities leaving the network.
480 At the same time implemented functions silc_server_remove_id
481 and silc_server_send_remove_id to receive and send REMOVE_ID
482 packets. The packet is used to notify routers in the network
483 about leaving entities. The ID removed will become invalid in
486 * Added function silc_idlist_del_server into server. Removes and
487 free's server entry from ID list.
489 * silc_server_private_message function now checks, if we are router,
490 that the destination ID really is valid ID, naturally.
492 * In router when NEW_ID packet is received (for new client) the
493 hash of the Client ID is saved in the ID Cache but the
494 client->nickname is set to NULL, instead of putting the hash
497 IDENTIFY command now also checks that client->nickname must be
498 valid. If it is not if will request the data from the server who
499 owns the client. Added new function
500 silc_server_command_identify_check.
502 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
503 to set the command to already allocated Command Payload.
505 * Tested private message sending in router environment with two
506 routers, two servers and two clients. Fixed minor bugs and now
509 * Fixed segfault from client's NAMES command. Used to crash if
512 * Forwarded packets must not be routed even if it is not destined
513 to the receiver. Changed server code comply with this.
515 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Added `require_reverse_mapping' boolean value to ServerParams
518 structure. If TRUE (not default) the server will require that
519 the connecting host has fully qualified domain name.
521 If the reverse mapping is not required and hostname could not be
522 found the IP address is used as hostname.
524 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Implemented version string checking to both client and server.
527 The check is incomplete currently due to the abnormal version
528 strings used in development version of SILC.
530 * Changed all command functions in server to use the new
533 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Changed char *data to unsigned char *data in ID Cache system to
536 support binary data as ID Cache data. Changed code to support
537 binary data in lib/silccore/idcache.c.
539 * Renamed silc_server_packet_relay_command_reply to
540 silc_server_command_reply as it is normal packet receiving
541 function. Rewrote the function to accept command replys for
542 servers and not only for clients.
544 * Mark remote router always as registered server if we are connecting
545 to it. Otherwise, commands sent by the router to us are ignored.
547 * All ID List find routines now returns the ID Cache Entry pointer
548 as well if requested.
550 * WHOIS command works now in router environment, tested with two
551 routers, two servers and two clients.
553 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
554 in router environment (as it is almost equivalent to WHOIS) but
555 hasn't been tested thoroughly. Added new functions:
557 silc_server_command_identify_parse
558 silc_server_command_identify_send_reply
559 silc_server_command_identify_from_client
560 silc_server_command_identify_from_server
562 * Disabled route cache adding because adding two different ID's with
563 same IP replaces the old cache entry thus giving wrong route.
564 The entry->router->connection is always the fastest route anyway
565 so route cache may not be needed. Of course, new routes maybe
566 established after receiving the ID when the entry->router->connection
567 might not be anymore the most optimal.
569 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Add route cache for received ID for fast routing.
573 * Added silc_server_packet_route to route received packet on router
574 that is not destined to us.
576 * Renamed silc_server_get_route to silc_server_route_get.
578 * Added id_string and id_string_len fields into SilcServer to
579 include encoded ServerID for fast comparing without excess
580 encoding of the ID's.
582 * Cleaned up WHOIS command on server side. Added following static
585 silc_server_command_whois_parse
586 silc_server_command_whois_check
587 silc_server_command_whois_send_reply
588 silc_server_command_whois_from_client
589 silc_server_command_whois_from_server
591 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
592 arguments in command replies. All command functions should be
593 updated to use this macro.
595 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Minor typo fixes on command reply handling on server.
599 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Added silc_server_command_add_to_channel internal routine to add
602 the client to the channel after router has created the channel and
603 sent command reply to the server.
605 * Added generic silc_server_send_command to send any command from
608 * Use static buffer with ID rendering instead of duplicating data.
610 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Fixed a channel user mode bug when joining to a channel server gave
613 everybody channel founder rights, oops.
615 * We mark ourselves as the router of the incoming server connection
616 if we are router ourselves. This way we can check in some packet
617 sending functions whether it is locally connected server. For
618 incoming router connections we put NULL.
620 * For router sending packets locally means now always sending the
621 packet cell wide; to local clients and local servers. For normal
622 server sending packet locally means sending it to only local
625 * Fixed the JOIN command to really work in router environment. If the
626 channel is created it is always created by the router. Router is
627 also responsible of making the initial joining to the channel,
628 sending JOIN notify to the sending server and distributing
629 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
630 does not exist server doesn't do anything else but forward the
631 command to the router which performs everything.
633 * Added silc_server_send_channel_key function to send the Channel Key
636 * Added silc_server_create_channel_key to create new channel key. The
637 channel key is now re-generated everytime someone joins or leaves
638 a channel, as protocol dictates. Note: channel->key_len is the
641 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Splitted server.[ch] finally. Created now packet_send.[ch] and
644 packet_receive.[ch] to separate packet sending and receiving
645 routines. The server.[ch] now includes everything else including
646 actual packet processing (writing and reading data) and other
649 Renamed silc_server_private_message_send_internal to
650 silc_server_send_private_message. The routine is still though
651 used only to relay private messages as server does not send
652 private messages itself.
654 Renamed silc_server_new_channel to silc_server_create_new_channel
655 and added new function sicl_server_new_channel that handles the
656 incoming New Channel packet. Added also new sending function
657 silc_server_send_new_channel to send New Channel Payload.
659 * Added new function silc_server_notify to process incoming notify
660 packet to the server/router. Server may then relay the notify
661 to clients if needed.
663 * Added new function silc_server_new_channel_user to process incoming
664 New Channel User packet. Router will redistribute the packet and
665 send JOIN notify to its local clients and locally connected servers
666 if needed. Normal server will send JOIN notify to its local client
667 on same channel when received this packet. Added also corresponding
668 sending function silc_server_send_new_channel_user to sent the
671 * Added boolean route argument to send_notif_to_channel and
672 packet_send_to_channel functions to attempt to route the packet
673 if it is TRUE and send only locally if it is FALSE.
675 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * silc_server_replace_id now broadcasts the received replace ID
678 packet if it is not broadcast packet already. The router must
679 broadcast to inform other routers about changed ID.
681 * Added backpointer to server's router into SilcServer context in
682 silcd/server_internal.h.
684 * Fixed silc_server_packet_broadcast to send correct broadcast
687 * The channel key is now distributed to the local client as soon
688 as it is received from the router (in router environment) so that
689 no other packet may be sent for the channel until client has
692 * silc_server_remove_channel_user now broadcasts the received
693 Remove Channel User packet if it is not broadcast packet already.
694 The router must broadcast to inform other routers about removed
697 * Added users field into SilcPacketContext that is a reference count
698 of the context. One can increase the reference count by calling
699 silc_packet_context_dup which is now changed to just increase the
700 reference count instead of duplicating the data. The reference
701 count is decresed by calling silc_packet_context_free that will
702 free the data after the reference count hits zero.
704 For now on the packet context and everything allocated into it
705 (including the raw packet from network) must be freed by calling
706 the new silc_packet_context_free function. Added also new function
707 silc_packet_context_alloc that must be used now to allocate the
708 context. This also means that if a routine is asynchronous from
709 silc_[client/server]_packet_parse_type the packet context must
710 be duplicated by calling silc_packet_context_dup. Otherwise it
711 gets free'd after silc_[client/server]_packet_parse_type returns.
712 Also, one must remember that if packet is duplicated then its
713 reference count must be decresed by calling the free function as
714 many times as it was duplicated.
716 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
717 from both client and server.
719 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Made joining to a channel working in router environment.
723 * Cleaned up JOIN command on server side and create function
724 silc_server_command_join_channel internal routine to make the
727 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Changed silc_command_pending list to SilcDList. Also, added
730 `ident' field to SilcServerCommandPending structure to identify
731 the reply and to call correct callback.
733 Added silc_server_command_pending_check function to replace the
734 corresnponding macro. The silc_command_pending list is not
737 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
738 to set identifier to previously allocated Command Payload. It
739 is used to set identifier for command when resending Command
742 * Added silc_command_payload_encode_payload to encode Command
743 Payload buffer from SilcCommandPayload structure.
745 * Added silc_argument_payload_encode_payload to encode Argument
746 payload buffer from SilcArgumentPayload structure.
748 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Changed WHOIS command to support router connection on server side.
751 The whois request is always sent to router unless the server is
752 standalone server. After server has received the reply from the
753 router will it send the reply to the client.
755 * Added silc_server_packet_broadcast into silcd/server.[ch] to
756 broadcast received broadcast packet. The function is used only
757 by router. The broadcast packet is always sent to the router's
760 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
761 render given ID to printable string, for log files for example.
763 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Made basic router to router connections working. At least they
766 can now connect to each other but nothing really works the way
767 they are supposed - yet.
769 * Added new initiator token to RouterConnection configuration
770 file in silcd/serverconfig.[ch]. It is used to tell whether we
771 are the initiator to the remote router or whether we'll expect
772 the other end to connect.
774 * Moved registering of listener task to silc_server_init, hence
775 the server starts listenning as soon as it is run, even if it
776 does not have connections to other routers. Let's see how well
779 * Changed default connection retry timeouts for more suitable in
782 * Removed cipher and such arguments from silc_idlist_add_client
783 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
784 Added new function silc_idlist_add_data to add the keys and stuff
787 * Added SilcIDListData structure and added it to SilcClientEntry
788 and SilcServerEntry as their first field in the structure. This
789 way we can explicitly cast the ID entries to the SilcIDListData
790 structure and get common data for the entries. In past, we had
791 to first check what type of connection it is and then cast it to
792 correct ID entry type. Now, we can directly cast the opaque
793 pointer to the SilcIDListData (no matter what ID entry it actually
794 is) and get the data needed.
796 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Wow, found a bug in scheduler. The scheduler uninitialized itself
799 in some circumstances even if threre were timeout tasks, though not
800 IO tasks, but tasks anyway. Now fixed.
802 * Defined SilcServerConnection structure to hold connection specific
803 stuff about directly connected servers and routers. The definition
804 is currently in silcd/server_internal.h. I thought about having
805 a bit more important role fro this struct but for now it is used
806 only when connecting to other server (or router actually).
808 * Added connecting retry support in server when connecting to
809 router(s). The retry feature implement exponential backoff
810 algorithm. Also, added SilcServerParams structure to hold default
811 parameters for server. For now, it include these retry settings
812 and are hard coded. After server is moded to be as Silc Server
813 Library this structure will be more important.
815 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Changed client librarys channel->clients table to SilcList and
818 changed code accordingly.
820 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Changed client's channel table to SilcList and changed code
823 accordingly. Also changed SilcChannelClientEntry to include back-
824 pointer to the channel so that client entry can use that structure
825 as list as well and we have fast cross-reference to the channel.
826 This change dramatically decreased the complexity of channel
827 handling with client entry and vice versa (removed one extra
828 loop when searching for channel entry from many functions).
830 * Changed server->sim from table to SilcDList and changed code
833 * NAMES command can now be used from user interface. It will show
834 the user list on the channel, neatly.
836 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
837 Code now saves realname of the user if it becomes available.
839 * Renamed configure.in to configure.in.pre and made ./prepare
840 script to automatically add correct version string to
841 configure.in which it creates from configure.in.pre.
843 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * NAMES command reply now shows users mode with the nickname when
848 * Moved silc_client_ch[u]mode[_char] functions from
849 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
850 place sucks, they are utility functions and should be in some
853 * Fixed some unsigned int's to unsigned short's. Patch by cras.
855 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
858 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Added TRQ (efficient deque and list library) into lib/trq. This is
863 a very good list library that is currently used in the SILC. Defined
864 SilcList API over the library because I didn't like the API very
865 much. See lib/trq/silclist.h for the API and examples of how to
866 use the API. Fixed various places in the code to use the new
867 SilcList API. The SilcList is meant for lists that has a structure
868 already defined as a list. It is not suitable to add just some
869 context to the list (in TRQ, the context is the list actually).
871 So, I defined SilcDList that can be used for the purpose where
872 predefined list structure does not exit. This can be used as
873 such list. Now some context just can be added to the SilcDList.
874 Currently this list is not used in the SILC just yet, though there
875 are a lot places where this can replace dynamically allocated
876 tables and I will fix these places, later, to use SilcDList.
877 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
878 and use TRQ internally).
880 Also fixed some annoying warning messages that the original TRQ
881 code generated. Also minor changes to TRQ's Makefile.in.
883 * Added support for querying by Client ID to both WHOIS and
884 IDENTIFY commands into server, as required by the protocol.
886 * Removed method function pointers from SilcBuffer structure. They
887 weren't used to anything and just increased the context size for
888 no good reason. This change also made silc_buffer_alloc and
889 silc_buffer_free functions inline functions.
891 * Disabled command flooding detection support until it's fixed so
892 that it accepts commands in but does not execute them more than once
895 * Added silc_net_localhost(), to return local hostname, into
896 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
897 that must be initialized before calling silc_client_init.
899 * Added new function: silc_server_send_notify_on_channels to send
900 notify messages to all channels client has joined. It is assured
901 that the message is sent only once per client.
903 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
904 lib/silcutil/silcutil.[ch] as silc_format function. The new
905 function is generic and is used by server as well, not only by
906 the logging routines.
908 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
909 the provided version string was not acceptable. Added new function:
910 silc_ske_check_version into lib/silcske/silcske.h. The function
911 must be implemented by the application (client or server) and it
912 does not reside in the SKE library. The function checks the version
913 string remote end sent.
915 * Added back pointers (to opaque context and to SilcSocketConnection)
916 into SilcPacketContext structure into lib/silccore/silcpacket.h.
918 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
919 duplicate packet context structure.
921 * Changed `notify' client operation to send same arguments as client
922 receives from server except for ID's. ID's are mapped to correct
923 ID entry and that is returned. Also, if channel entry is not sent
924 by server but the notify is for channel the channel entry is sent
925 to application (otherwise application doesn't know that it is for
926 channel (library gets it from packet's Destination ID)).
928 * Added silc_client_remove_from_channels into client library to
929 remove a client from all channels it has joined to. Used when
930 received SIGNOFF notify from server. Added also new function
931 silc_client_replace_from_channels to replace old ID entry with
932 new ID entry on all channels. Used when received NICK_CHANGE
935 * Fixed ID Cache list handling in silc_idlist_get_client in
936 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
937 to get (or query) client by ID.
941 * Added connection authentication status message defined by the
942 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
943 support for these into the code in client and server side.
945 * Added generic function silc_client_send_command to send any command
946 with variable argument list. Application should use this function
947 to send commands if the command functions provided by the library
948 does not suite for the application's user interface needs.
950 * Added new `failure' client operation. Application is notified about
951 received failure packet if client is executing a protocol. In this
952 case the protocol's execution has failed.
954 * Added SKE's end notify to send the SKE_SUCCESS notify message that
955 is required by the protocol.
957 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
958 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
961 * Added status flag to SilcSKE object to indicate realtime status
964 * Application receives now exactly same command reply arguments as
965 the library receives from server. However, if ID is received the
966 corresponding ID entry is returned to the application (eg. Client
967 ID is mapped to correct SilcClientEntry entry and that is returned).
968 Changed command_reply client operation due to this change.
970 * Changed all ID's in commands and in command replys as ID Payloads.
971 Change affected both client and server side codes.
973 All ID's sent in SILC network (with execption of ID's in SILC
974 Packet header) are sent in ID Payload to support variable length
977 * Server now notifies nick changes and notifies all clients on
978 the channels about the new nickname (about the new Client ID,
981 * Implemented CMODE command to change channel modes. Supports all
982 channel modes defined by the protocol specs except ban and invite
983 lists. (Also, private channel key mode is supported but support for
984 setting private channel key in client is missing, thus, this mode
985 has no effect on client side (except that server requires that the
986 client uses private channel key and normal channel traffic does not
989 Also, invite mode works per se, but INVITE command does not work
990 yet correctly, so you can set channel as invite only channel but
991 inviting clients to the channel does not work (it is yet to be
992 thought what's the best way to do it).
994 * Added new command SILC_COMMAND_CUMODE to change user mode on the
995 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
996 Implemented CUMODE command to change user's mode on the channel.
997 Supports all modes defined by the protocol specs.
999 * Added NAMES command reply to return users modes on the channel.
1001 * Removed unnecessary and slow ciphers from lib/silccrypt.
1003 * Set SO_KEEPALIVE option to connection sockets by default.
1005 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1007 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1008 redefined the Notify Payload into protocol specs.
1010 * Added silc_id_payload_parse_id to get ID directly from raw
1013 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1016 accept searching by Client ID as well.
1018 * Added support for LEAVE and SIGNOFF notify types in client library.
1020 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1021 to parse ID Payload from raw data.
1023 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Added flags parameter into silc_ske_assemble_security_properties
1026 function in lib/silcske/silcske.[ch].
1028 * Changed notify client operation to fit better for notify messages
1029 sent by server. The notify payload received from server is now
1030 passed to the application (after parsing it to SilcNotifyPayload).
1031 It is application's responsibility to retrieve the arguments
1032 from the payload and show the message the way it wants. The message
1033 sent by server is implementation specific.
1035 * Changed public keys to comply with the protocol specification.
1036 Old public keys are not supported anymore and are not compatible.
1038 * Removed nickname from Channel Payload as the latest draft removed
1039 it. The client must resolve the nickname from the NAMES command
1040 reply received when it joined the channel.
1042 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1044 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Fixed some errors in protocol specification drafts.
1048 * Created lib/silccore/silcnotify.c to implement Notify Payload
1049 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1050 generic payloads described by protocol specifications. The file
1051 includes implementations for ID Payload and Argument Payload.
1053 * Changed Command Payload implementation to use the new Argument
1054 Payload. Changed command_xxxx_payload to command_payload_xxxx
1055 to comply with SILC coding conventions.
1057 * Added suppport for Argument Payload handling in Notify Payload
1058 implementation as protocol requires it. Added the new support
1059 into server and client lib as well.
1061 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Added support for multiple nicknames on same channel. [n] is
1064 added locally to the nickname if there are more than one same
1065 nicknames on the channel.
1067 * Server now sends all nicknames that matched WHOIS request.
1068 Client also shows the list received from server.
1070 * Added TOPIC command to client side. User can now set and show
1071 current topic on channel.
1073 * Added MOTD command to client and server. Also, server sends the
1074 motd when client connects to the server.
1076 * Changed version strings to comply ISO 8601.
1078 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Fixed protocol error handling in client library. It should now
1081 cope even if the SKE fails for some reason.
1083 * Made new protocol specification drafts for submitting to IETF.
1085 * Implemented TOPIC command to server in silcd/command.c.
1087 * Added two new notify types into lib/silccore/silcnotify.h:
1088 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1089 notify nickname change and topic setting/change on a channel.
1091 * API change of command_reply operation in client library. The
1092 application gets now the status type received from server as well.
1094 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1098 * Cras fixed and optimized the packet handling even further and
1099 it should work now. Minor change to the prototype of function
1100 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1102 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added new function into lib/silcutil/silcschedule.[ch]:
1105 silc_schedule_with_fd to select() a specified fd. The function
1106 returns after timeout expires or data arrives or goes. The
1107 function is used by packet routines to wait that all data is
1108 received from network.
1110 * Fixed data reading from network in lib/silccore/silcpacket.c.
1111 The code now assures that all data is read from the fd and then
1112 continues packet processing. This was a bug fix since the code
1113 used to drop some data in some circumstances.
1115 * Added new function into lib/silcclient/client.[ch]:
1116 silc_client_start_key_exchange to start key exchange after
1117 connection has been established to server. The code internally
1118 now uses this funtion but its main purpose was to provide it
1119 for applications that perform their own connecting. After
1120 application has created a connection it merely calls this
1121 function to start the key exchange between client and server.
1122 The library takes care of everything else after that.
1124 Updated also lib/silcclient/README to explain the usage of
1127 * Do not send to application information that connection has
1128 been established. Application gets notified it by connect
1131 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Applied cras's patch to add silc_schedule_one function. The
1134 function runs scheduler once and returns.
1136 * Fixed the scheduler after cras messed it up. The timeout
1137 handling works now as it's supposed to work.
1139 * Added into lib/silccore/ silcnotify.h to include notify
1140 message types support. Changed silc_server_send_notify*
1141 functions, in server.[ch], to support those new notify types.
1142 Added the support for the notify types into client library,
1143 as well. Added new notify client operation into ops.h in
1146 * Changed silc_server_packet_send_to_channel to send normal
1147 packets instead of just channel message packets. The function
1148 is now used to send the notify packets to channels. It is not
1149 used to send channel message packets anymore, as server never
1152 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1153 va_arg()s as it seems to require it nowadays. I guess, if SILC
1154 is compiled with older va_arg() the new code should work anyway.
1156 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Splitted core library. Core library (lib/silccore) includes
1159 now only SILC protocol specific core (and common) components.
1160 Created new utility library (lib/silcutil) that includes more
1161 generic purpose stuff. The stuff for util library was taken
1162 from the old core library. This was minor and easy split.
1164 * Created SILC Client Library (lib/silcclient) that includes
1165 implementation of the SILC client without user interface. This
1166 was major move from silc/ directory. The code has been changed
1167 so that it is transparent towards the user interface. The
1168 silc/ directory includes now the same user interface as before
1169 and it uses the new client library. Read lib/silcclient/README.
1170 Basicly, the client library performs everything else related
1171 to SILC except user interface handling. Also, configuration
1172 files are considered to be part of user interface and library
1173 does not handle them.
1175 This change also changed a lot of structures, function naming etc.
1176 Most important change was that SilcClientWindow object was
1177 renamed to SilcClientConnection in the client library. Created
1178 also new file lib/silcclient/ops.h. Also added new files
1179 silc/local_command.[ch] and silc/client_ops.[ch].
1181 All these changes were made to make it easier for user interface
1182 designers to create what ever user interface for the SILC client
1185 It is also expected that the server will be moved to lib
1186 directory as well and SILC Server Library will be created;
1187 sometimes in the future.
1189 * Removed Local commands from lib/silccore/silccommand.h as
1190 they are application specific and new client library does not
1191 handle any of those anymore.
1193 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1194 old client implementation in silc/.
1196 * Added support for callback functions in SILC_LOG_* macros.
1197 Application can now set its own callbacks that will be called
1198 instead of using the default functions that will always print
1199 the debug messages to stderr (or stdout). Also, debugging can
1200 now be disabled by setting silc_debug to FALSE and re-enabled by
1201 setting it to TRUE. Note, that logging will still work even
1202 if debugging is disabled.
1204 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1205 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1206 silc_log_reset_debug_callbacks.
1208 * To enable debugging in silc client one must give now -d
1209 option on command line.
1211 * Changed silc_schedule_init to automatically allocate task queues
1212 if they are not allocated before calling it.
1214 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Added GMP 3.1 into math library.
1218 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1221 a channel in SILC network. The packet is used by servers and
1222 routers to notify other routers that user has left a channel.
1223 This little feature was missing until now. Added the feature
1224 to protocol specification as well.
1226 Added functions: silc_server_send_remove_channel_user and
1227 silc_server_remove_channel_user into server.[ch].
1229 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1230 lib/silccore/silcpacket.h. However, they are not implemented
1233 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Fixed joining to a channel and sending channel messages
1236 between server and router. The channel message sending should
1237 now work inside a cell.
1239 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Fixed the private message sending between server and router.
1242 The private message sending should now work inside a cell.
1244 * Added silc_server_replace_id into server.[ch] to replace
1245 existing ID in the SILC network.
1247 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1248 and silc_idlist_replace_server_id into idlist.[ch] in server.
1250 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Fixed the server to server connections. Server can again now
1253 connect to router. Router to router connections probably does
1256 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added dynamic protocol registering support. Now protocols can
1259 registered and unregistered on the fly. Patch by cras.
1261 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1263 * Added lib/contrib directory to hold routines that some platforms
1264 don't have but are needed by SILC.
1266 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1267 into lin/contrib to provide getopt() and getopt_long() for
1268 those who don't have it.
1270 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1272 * Added AWAY command to client. When away message is set and
1273 client receives a private message packet the client automatically
1274 replies to the sender with the away message.
1276 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1277 bug seemed to be the cause of recent problems when compiling
1280 * Added version detection support to SKE protocol specification
1281 and added the new changes to the SKE implementation as well.
1282 There were other minor changes in the SKE protocol as well.
1284 Many changes in lib/silcske/silcske.[ch] and in
1285 lib/silcske/payload.[ch].
1287 * Added ^U functionality, clear input line. Patch from cras.
1289 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Mainly small bugfixes on core library. Fixed some debugging
1292 logging and buffer overflow in silclog.c.
1294 * Updated config.sub and config.guess on the distribution tree.
1296 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added command lagging support in server. Client may execute
1299 commands now only once in two seconds.
1301 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1303 * Optimized packet reception. MAC computation and checking is now
1304 also more optimized. A lot previously duplicated code is now
1305 used as generic by both client and server.
1307 * Fixed key pair generation in clientutil.c
1309 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added into lib/silccore/silcbufutil.[ch] new function;
1312 silc_buffer_realloc.
1314 * Moved generic packet sending/encryption functions to
1315 lib/silccore/silcpacket.[ch] from client and server. Some
1316 rewriting of the functions.
1318 * Moved all generic packet reception/decryption functions to
1319 lib/silccore/silcpacket.[ch] from client and server. The
1320 packet processing is now much cleaner in both client and server.
1321 These were major changes in both client and server.
1323 * Created many common functions in server to do packet sending.
1324 Previously code were duplicated a lot, this has been removed
1327 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Rewrote major parts of the ID cache system. Don't know
1330 whether it is better now or not but at least the API is more
1333 * Major rewrite on ID cache stuff on client because of the ID
1334 cache API changes. Added idlist.c to client.
1336 * Also major rewrite on ID cache stuff on server as well.
1337 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1338 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1339 in hand, instead they are all put into the ID cache system now.
1340 All server_idlist_* routines uses ID cache now instead of
1341 traversing its own lists (those lists does not exist anymore).
1342 SilcIDList though still exists. Also, SilcXXXEntry's are
1345 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Finally made the SKE implementation compliant to the protocol
1348 specification. All mp integers are now binary encoded as
1349 opposed being HEX encoded.
1351 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1354 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1355 functions: silc_[encode/decode]_pem. Also added function
1356 silc_encode_pem_file to PEM encode with newlines ('\n') for
1359 * SILC public keys are now encoded either PEM or binary. Same
1360 option is for private keys as well. By default private keys
1361 are binary encoded and public keys PEM encoded. Silly HEX
1362 encoding were removed.
1364 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1365 function to create fingerprints.
1367 * Fixed a bug in SHA1; does not change the original data anymore.
1369 * Partly implemented INFO command on client and server side.
1370 Fixed CLEAR command. Changes to SERVER command; show current
1371 server(s) when giving command without arguments. Added
1372 VERSION command to client.
1374 * Added check to server that unregistered connections cannot
1375 execute commands (unless it is specificly allowed).
1377 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1379 * Fixed screen refresh.
1381 * Fixed channel joining bug from client. On some circumstances
1382 client tried to join to a channel it had already joined.
1384 * Added public key verification process into client's protocol.c.
1385 The client now verifies the public key from user and saves
1386 it into ~./silc/serverkeys/ directory.
1388 Added into: clientutil.[ch]: silc_client_verify_server_key.
1390 * Changed SKE protocol's silc_ske_initiator_finish function
1391 to accept callback function that verifies the received public
1392 key. Removed old silc_ske_verify_public_key function.
1394 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1397 silc_pkcs_private_key[_data]_set.
1399 * Made the password and public authentication more cleaner in
1400 server's protocol.c.
1402 * Removed historic and obsolete protocol `channel_auth' from
1403 both client and server.
1405 * Removed wrong way of sending command status messages from
1406 server to client in server's command.c. The old way violated
1407 protocol specification.
1409 Changes to silccore/silccommand.[ch]: removed
1410 silc_command_encode_status_payload -> not needed anymore,
1411 changed silc_command_encode_payload_va to accept extra
1412 argument on variable argument list. The argument type must
1413 now be provided to the function. Also, added new function:
1414 silc_command_encode_reply_payload_va which is same as
1415 normal command_encode_payload_va except command status type
1416 is provided as extra argument.
1418 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1420 * Added ~./silc directory handling. The directory includes the
1421 public and private keys for the client.
1423 Added silc_client_check_silc_dir, silc_client_create_identifier
1424 and silc_client_load_keys.
1426 * Implemented SILC protocol compliant public key. Added public
1427 and private key saving to and loading from files.
1429 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1430 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1431 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1432 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1433 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1435 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1436 silc_pkcs_load_[public/private]_key.
1438 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Added silc_server_get_route (route.[ch]) to get connection
1441 data for the fastest route for given ID.
1443 * Implemented INVITE command on client and server. The command
1444 were re-defined in the SILC Protocol Specification and the
1445 implementation now complies with the specification.
1447 * Implemented PING command on client and server.
1449 * Implemented NAMES command on client and server. The server side
1450 supports currently only normal server not router server yet.
1451 Some changes to NAMES definition in SILC protocol specification.
1453 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Implemented LEAVE command on client and server.
1457 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1458 again. This change was made to the protocol as well. Server
1459 should not violate the protocol specification anymore.
1461 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1464 was tested. SOCKS4 was not but should work anyway.
