3 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4 send keepalive packets. The packet can be sent by clients,
7 Added function silc_socket_set_heartbeat into the file
8 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
9 If not set, the heartbeat is not performed. The actual
10 heartbeat is implemented in the low level socket connection
11 library. However, application is responsible of actually
14 Added silc_server_send_heartbeat to send the actual heartbeat
15 packet into silcd/packet_send.[ch]. Server now performs
16 keepalive with all connections.
18 * Added silc_task_get_first function into lib/silcutil/silctask.c
19 to return the timeout task with shortest timeout. There was a bug
20 in task unregistration that caused problems. TODO has been
21 updated to include that task system must be rewritten.
23 * The client library will now resolve the client information when
24 receiving JOIN notify from server for client that we know but
25 have incomplete information.
27 * Rewrote parts of silc_server_remove_from_channels and
28 silc_server_remove_from_one_channel as they did not remove the
29 channel in some circumstances even though they should've.
31 * Encryption problem encountered in server:
33 The LEAVE command used to send the Channel Key packet to the
34 router immediately after generating it. However, the code
35 had earlier sent Remove Channel user packet but not immediately,
36 ie. it was put to queue. The order of packets in the router
37 was that Channel Key packet was first and Remove Channel User
38 packet was second, even though they were encrypted in the
39 reverse order. For this reason, MAC check failed. Now, this
40 is fixed by not sending the Channel Key packet immediately but
41 putting it to queue. However, this is more fundamental problem:
42 packets that are in queue should actually not be encrypted
43 because packets that are sent immediately gets encrypted
44 actually with wrong IV (and thus MAC check fails). So, packets
45 that are in queue should be encrypted when they are sent to
46 the wire and not when they put to the queue.
48 However, the problem is that the current system has not been
49 designed to work that way. Instead, the packet is encrypted
50 as soon as possible and left to the queue. The queue is then
51 just purged into wire. There won't be any fixes for this
52 any time soon. So, the current semantic for packet sending
55 o If you send packet to remote host and do not force the send
56 (the packet will be in queue) then all subsequent packets to the
57 same remote host must also be put to the queue. Only after the
58 queue has been purged is it safe again to force the packet
61 o If you send all packets immediately then it safe to send
62 any of subsequent packets through the queue, however, after
63 the first packet is put to queue then any subsequent packets
64 must also be put to the queue.
66 Follow these rules and everything works fine.
68 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Added new function silc_server_remove_clients_by_server to
71 remove all client entries from ID list when the server connection
72 is lost. In this case it is also important to invalidate all
73 client entires as they hold the invalid server entry. This
74 fixes fatal bug when server has lost connection and will reconnect
77 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
79 * Made some sanity checks to silc_server_daemonise like to check
80 whether the requested user and group actually exists.
82 * Added sanity check to SKE's silc_ske_responder_finish to check
83 that the public and private key actually is valid.
85 * Invalidate the client's nickname when receiving Replace ID
86 packet and the Client ID is being replaced. This means that the
87 server will query the nickname if someone needs it (client)
90 * Sort the ID Cache in client library when the ID Cache data
91 has changed (needs sorting).
93 * Do not allow for SILC client to create several connections to
94 several servers. The client does not support windows right now
95 and generating multiple connections causes weird behaviour.
97 Irssi-silc client does support windows and can handle several
98 connections without problems, see: www.irssi.org and SILC plugin.
100 * Fixed some places where client was added to the IDList. The
101 rule of thumb is following (in order to get everything right):
102 If the client is directly connected local client then the
103 `connection' argument must be set and `router' argument must be
104 NULL to silc_idlist_add_client function. If the client is not
105 directly connected client then the `router' argument must
106 bet set and the `connection' argument must be NULL to the
107 silc_idlist_add_client function.
109 * The funtion silc_server_packet_send_local_channel actually did
110 not check whether the client was locally connected or not. It
111 does that now. Fixed a bug related to LEAVE command.
113 * Fixed Remove Channel User payload parsing bug in server's
114 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
116 * The server's silc_server_save_channel_key now checks also the
117 global ID list for the channel as it might not be in the local
118 list. Fixed a bug related to LEAVE command.
120 * Is this the end of the [<unknown>] buglet that has been lurking
121 around for a long time? A little for loop fix in server's
122 silc_server_command_whois_parse that is used by both IDENTIFY
123 and WHOIS command. At least, this was a clear bug and a cause
124 of one type of [<unknown>] buglet.
126 * WHOIS and IDENTIFY commands call the function
127 silc_server_command_[whois/identify]_check function even if
128 we are not router server.
130 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
132 * Added --with-gmp configuration option. If set the GMP
133 is always compiled in the SILC source tree. If not set then
134 it is checked whether the system has the GMP3 installed. If
135 it has then the GMP won't be compiled (the system's headers
136 and library is used), if it doesn't have it then the GMP is
137 compiled in the SILC source tree.
139 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Changed RSA private exponent generation to what PKCS #1
142 suggests. We try to find the smallest possible d by doing
143 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
144 not security fix but optimization.
146 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Added new config entry [Identity] to fork the server and run
149 it as specific user and group. A patch from Bostik.
151 * Imported Dotconf configuration library into lib/dotconf.
152 This will be used to create the SILC configuration files later.
153 It will appear in the distsribution after this commit.
155 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * A big code auditing weekend happening. Auditing code for
158 obvious mistakes, bugs and errors. Also, removing any code
161 Removed files for being obsolete:
163 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
164 inline in the file lib/silcutil/silcbuffer.h)
166 o lib/silcutil/silcbufutil.c (the header has inline versions)
168 Changed code to fix possible error conditions:
170 o The buffer formatting routines now check that the destination
171 buffer really has enough space to add the data. This applies for
172 both buffer formatting and unformatting
173 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
174 unformatting was changed to accomodate following rules:
175 XXX_*STRING_ALLOC will allocate space for the data into the pointer
176 sent to the function while XXX_*STRING will not allocate or copy
177 the data into the buffer. Instead it sets the pointer from the
178 buffer into the pointer sent as argument (XXX_*STRING used to
179 require that the pointer must be allocated already). This change
180 makes this whole thing a bit more consistent and more optimized
181 (note that the data returned in the unformatting with XXX_*STRING
182 must not be freed now). The routines return now -1 on error.
184 o Tried to find all code that use buffer_format and buffer_unformat
185 and added return value checking to prevent formatting and
186 especially unformatting errors and possible subsequent fatal
189 o Changed ske->x and ske->KEY to mallocated pointers in
190 lib/silcske/silcske.h. Fixed possible data and memory leak.
192 o Added return value checking to all *_parse* functions. Fixed
193 many memory leaks as well.
195 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
196 so that buffer overflows would not happen. All code now also
197 checks the return value as it can fail.
199 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Added reconnection support to server if the normal server looses
202 its connection to the router (for example if router is rebooted).
203 The server performs normal reconnection strategy implemented
204 to the server. Affected file silcd/server.c.
206 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Added new packet type SILC_PACKET_SET_MODE that is used to
209 distribute the information about changed modes (for clients,
210 channels and clients channel modes) to all routers in the
211 network. Updated the protocol specification accordingly.
213 Added functions into silcd/packet_send.c and
214 silcd/packet_receive.c: silc_server_send_set_mode,
215 silc_server_set_mode.
217 Added new files silcmode.[ch] into lib/silccore that implements
218 the encoding and decoding of Set Mode Payload. Added new type
219 SilcSetModePayload. Moved the definitions of different modes
220 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
222 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
224 * Oops, a little mistake in server's connection authentication
225 protocol. The protocol is not ended with FAILURE but with
226 SUCCESS if the authentication is Ok. :) Affected file is
229 * Implemented NICK_CHANGE notify handling in server in the file
230 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
231 the local clients on the channel. After the changing nickname
232 in router environment snhould work and the [<unknown>] nickname
233 should appear no more.
235 The silc_server_replace_id function that receives the Replace ID
236 payload now sends the NICK_CHANGE notify type also in the file
237 silcd/packet_receive.c
239 * Changed WHOIS and IDENTIFY command to support the maximum amount
240 of arguments defined in protocol specs (3328 arguments). This
241 fixed a bug that caused problems when there were more than three
244 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Added extra parameter, command identifier, to the
247 silc_client_send_command so that explicit command identifier
250 Changed that ID list routines uses specific command identifier
251 when sending WHOIS/IDENTIFY requests to the server so that they
252 can be identified when the reply comes back.
254 Affected files lib/silcclient/command.[ch],
255 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
257 * Added `sender' argument to silc_server_packet_send_to_channel
258 to indicaet the sender who originally sent the packet to us
259 that we are now re-sending. Ignored if NULL. Affected file
260 silcd/packet_send.[ch].
262 * Added some server statistics support in silcd/server_internal.h
263 SilcServerStatistics structure and around the server code. Also
264 send some nice statistics information when client is connecting
267 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Fixed channel ID decoding in server's JOIN command reply in
270 silcd/command_reply.c
272 * Fixed braodcasting of replace ID payload to not to send it if
273 we are standalone server in silcd/packet_receive.c.
275 * Fixed all channel message sending routines to not to send
276 packets to clients that has router set, since they are routed
277 separately in the same function earlier. Affects file
278 silcd/packet_send.c and all channel packet sending functions.
280 * In USERS reply, res_argv[i] are not allocated, the table
281 is allocated. Thus changed that free the table, not its
284 * In server's whois_check and identify_check if the client is
285 locally connected do not send any WHOIS commands - they are not
288 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Fixed some minor bugs in client when sending WHOIS command. The
291 arguments was in wrong order.
293 * Removed statis function add_to_channel from server in
294 silcd/command.c that was previously used with the joining but
297 * Tested USERS command in router environment successfully with two
298 routers, two servers and two clients.
300 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
302 * Reorganized the USERS command and command reply in client library
303 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
304 When the command is given by user we register a pending command
305 callback that will reprocess the command after the reply has been
306 received from the server. When reprocessing the packet we then
307 display the information. Thus, the USERS information is displayed
308 now in the command callback instead of in the command reply
309 callback. The processing of the command is same as previously
310 when server has sent the command reply in the JOINing process.
312 * Added to USERS command in silcd/command_reply.c to join the client,
313 we didn't use to know about, to the channel after we've created
314 a client entry for it. Also, for clienet we did know already still
315 check whether it is on the channel or not and add it if not.
317 * Removed silc_server_command_join_notify as the function and its
320 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Changed the client's pending command handling to the same as the
323 server's pending command handling. It is also now possible to
324 execute command reply functions from other command reply
325 function as the function callbacks for commands and command
326 replies are one and same. The pending commands are not static
327 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
328 in client connection context. Thus, pending commands are server
329 connection specific as it is convenient.
331 Changed the function silc_client_command_pending and
332 silc_client_command_pending_del and added new function
333 silc_client_command_pending_check. Removed the
334 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
337 * Added cmd_ident, current command identifier, to the client
338 connection context in lib/silcclient/client.h to keep track on
339 command identifiers used in command sending. Client's command reply
340 function handling now supports the mandatory command identifiers.
342 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
343 funtions in client to fully support pending command callbacks.
345 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
346 as one of the arguments to the application in the command reply
349 * NOTE: The FORWARDED flag is depracated. It used to be depracated
350 before first releasing SILC but came back. Now it is removed again
351 and should come back nomore. The FORWARDED flag was used only
352 by the JOINing procedure by forwarding the command packet to router.
353 Now, the JOINing procedure has been changed to more generic (due
354 to various router environment issues) and FORWARDED is not needed
355 anymore for anything. The protocol specification is yet to be
358 Now, removed silc_server_packet_forward from server and the flag
359 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
361 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Renamed NAMES command to USERS command. The NAMES was named that
364 due to historical reasons. Now it is renamed. Also, rewrote
365 parts of the USERS command. The nickname list is not sent anymore
366 by the server. Only Client ID and mode lists are sent in the USERS
367 command. Changed this also to the protocol specification.
369 The client now resolves the names and stuff after it receives
370 the USERS list from the server when joining to the channel.
372 * WHOIS and IDENTIFY commands has been changed to support multiple
373 Client ID's per command. One can now search for multiple users
374 in the network by sending only one WHOIS or IDENTIFY command.
375 Changed the code and the protocol specifications.
377 * Removed silc_server_command_identify_parse and changed that IDENTIFY
378 uses silc_server_command_whois_parse to parse the request. */
380 * If normal server, do not parse the WHOIS and IDENTIFY requests
381 before sending it to the router. Saves some time.
383 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Fixed JOIN command on client library. Wrong number of arguments
386 used to crash the client.
388 * Added silc_server_channel_has_global function to check whether
389 channel has global users or not.
391 * Added silc_server_channel_has_local function to check whether channel
392 has locally connected clients on the channel.
394 * The silc_server_remove_from_one_channel now checks whether the
395 channel has global users or not after given client was removed from
396 the channel. It also checks whether the channel has local clients
397 on the channel anymore. If it does not have then the channel entry
398 is removed as it is not needed anymore.
400 * The silc_server_notify now checks on JOIN notify whether the joining
401 client is one of locally connected or global. If it is global then
402 the channel has now global users on the channel and that is marked
403 to the channel entry. Also, it now saves the global client to
404 global list who is joining and JOINs it to the channel. This is
405 for normal server, that is.
407 Changed silc_server_send_notify_on_channel,
408 silc_server_packet_relay_to_channel and
409 silc_server_packet_send_to_channel check if we are normal server
410 and client has router set (ie. global client) do not send the
411 message to that client, as it is already routed to our router.
413 * Implemented LEAVE notify type handling in silc_server_notify
416 * Tested LEAVE command in router environment successfully. Tested
417 with two routers, two servers and two clients.
421 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
423 * Implemented SIGNOFF notify type handling in silc_server_notify
426 * silc_server_remove_id now removes the client entry from all channels
427 it has joined and thusly sends SIGNOFF notify type.
429 * Rewrote the NAMES list generation in server by removing two excess
430 loops. The lists are created now inside one loop.
432 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
434 * silc_server_remove_channel_user checks now also global list
435 for channel and client.
437 * silc_server_new_channel_user checks now both local and global
438 list for channel and client. Fixed a bug in client id decoding.
439 Used to decode wrong buffer.
441 * silc_server_channel_message checks now both local and global
442 list for channel entry.
444 * Tested channel joining (hence JOIN) in router environment
445 successfully. Tested with two routers, two servers and two
448 * Tested channel message sending in router environment successfully.
450 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Added silc_server_save_channel_key into server.[ch] to save the
453 received channel key in Channel Key payload processing. It is
454 also used in JOIN command reply handling.
456 Equivalent function silc_client_save_channel_key added into
457 client.[ch] into client library.
459 * Changed JOIN command reply to send information whether the channel
460 was created or not (is existing already) and the channel key
461 payload. Changed protocol specs accordingly.
463 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
464 the request was sent by ID and not by nickname. Crashed on
467 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
470 now correctly save the received data.
472 * silc_server_free_sock_user_data now notifies routers in the
473 network about entities leaving the network.
475 At the same time implemented functions silc_server_remove_id
476 and silc_server_send_remove_id to receive and send REMOVE_ID
477 packets. The packet is used to notify routers in the network
478 about leaving entities. The ID removed will become invalid in
481 * Added function silc_idlist_del_server into server. Removes and
482 free's server entry from ID list.
484 * silc_server_private_message function now checks, if we are router,
485 that the destination ID really is valid ID, naturally.
487 * In router when NEW_ID packet is received (for new client) the
488 hash of the Client ID is saved in the ID Cache but the
489 client->nickname is set to NULL, instead of putting the hash
492 IDENTIFY command now also checks that client->nickname must be
493 valid. If it is not if will request the data from the server who
494 owns the client. Added new function
495 silc_server_command_identify_check.
497 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
498 to set the command to already allocated Command Payload.
500 * Tested private message sending in router environment with two
501 routers, two servers and two clients. Fixed minor bugs and now
504 * Fixed segfault from client's NAMES command. Used to crash if
507 * Forwarded packets must not be routed even if it is not destined
508 to the receiver. Changed server code comply with this.
510 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Added `require_reverse_mapping' boolean value to ServerParams
513 structure. If TRUE (not default) the server will require that
514 the connecting host has fully qualified domain name.
516 If the reverse mapping is not required and hostname could not be
517 found the IP address is used as hostname.
519 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Implemented version string checking to both client and server.
522 The check is incomplete currently due to the abnormal version
523 strings used in development version of SILC.
525 * Changed all command functions in server to use the new
528 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Changed char *data to unsigned char *data in ID Cache system to
531 support binary data as ID Cache data. Changed code to support
532 binary data in lib/silccore/idcache.c.
534 * Renamed silc_server_packet_relay_command_reply to
535 silc_server_command_reply as it is normal packet receiving
536 function. Rewrote the function to accept command replys for
537 servers and not only for clients.
539 * Mark remote router always as registered server if we are connecting
540 to it. Otherwise, commands sent by the router to us are ignored.
542 * All ID List find routines now returns the ID Cache Entry pointer
543 as well if requested.
545 * WHOIS command works now in router environment, tested with two
546 routers, two servers and two clients.
548 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
549 in router environment (as it is almost equivalent to WHOIS) but
550 hasn't been tested thoroughly. Added new functions:
552 silc_server_command_identify_parse
553 silc_server_command_identify_send_reply
554 silc_server_command_identify_from_client
555 silc_server_command_identify_from_server
557 * Disabled route cache adding because adding two different ID's with
558 same IP replaces the old cache entry thus giving wrong route.
559 The entry->router->connection is always the fastest route anyway
560 so route cache may not be needed. Of course, new routes maybe
561 established after receiving the ID when the entry->router->connection
562 might not be anymore the most optimal.
564 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Add route cache for received ID for fast routing.
568 * Added silc_server_packet_route to route received packet on router
569 that is not destined to us.
571 * Renamed silc_server_get_route to silc_server_route_get.
573 * Added id_string and id_string_len fields into SilcServer to
574 include encoded ServerID for fast comparing without excess
575 encoding of the ID's.
577 * Cleaned up WHOIS command on server side. Added following static
580 silc_server_command_whois_parse
581 silc_server_command_whois_check
582 silc_server_command_whois_send_reply
583 silc_server_command_whois_from_client
584 silc_server_command_whois_from_server
586 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
587 arguments in command replies. All command functions should be
588 updated to use this macro.
590 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Minor typo fixes on command reply handling on server.
594 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Added silc_server_command_add_to_channel internal routine to add
597 the client to the channel after router has created the channel and
598 sent command reply to the server.
600 * Added generic silc_server_send_command to send any command from
603 * Use static buffer with ID rendering instead of duplicating data.
605 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Fixed a channel user mode bug when joining to a channel server gave
608 everybody channel founder rights, oops.
610 * We mark ourselves as the router of the incoming server connection
611 if we are router ourselves. This way we can check in some packet
612 sending functions whether it is locally connected server. For
613 incoming router connections we put NULL.
615 * For router sending packets locally means now always sending the
616 packet cell wide; to local clients and local servers. For normal
617 server sending packet locally means sending it to only local
620 * Fixed the JOIN command to really work in router environment. If the
621 channel is created it is always created by the router. Router is
622 also responsible of making the initial joining to the channel,
623 sending JOIN notify to the sending server and distributing
624 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
625 does not exist server doesn't do anything else but forward the
626 command to the router which performs everything.
628 * Added silc_server_send_channel_key function to send the Channel Key
631 * Added silc_server_create_channel_key to create new channel key. The
632 channel key is now re-generated everytime someone joins or leaves
633 a channel, as protocol dictates. Note: channel->key_len is the
636 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Splitted server.[ch] finally. Created now packet_send.[ch] and
639 packet_receive.[ch] to separate packet sending and receiving
640 routines. The server.[ch] now includes everything else including
641 actual packet processing (writing and reading data) and other
644 Renamed silc_server_private_message_send_internal to
645 silc_server_send_private_message. The routine is still though
646 used only to relay private messages as server does not send
647 private messages itself.
649 Renamed silc_server_new_channel to silc_server_create_new_channel
650 and added new function sicl_server_new_channel that handles the
651 incoming New Channel packet. Added also new sending function
652 silc_server_send_new_channel to send New Channel Payload.
654 * Added new function silc_server_notify to process incoming notify
655 packet to the server/router. Server may then relay the notify
656 to clients if needed.
658 * Added new function silc_server_new_channel_user to process incoming
659 New Channel User packet. Router will redistribute the packet and
660 send JOIN notify to its local clients and locally connected servers
661 if needed. Normal server will send JOIN notify to its local client
662 on same channel when received this packet. Added also corresponding
663 sending function silc_server_send_new_channel_user to sent the
666 * Added boolean route argument to send_notif_to_channel and
667 packet_send_to_channel functions to attempt to route the packet
668 if it is TRUE and send only locally if it is FALSE.
670 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
672 * silc_server_replace_id now broadcasts the received replace ID
673 packet if it is not broadcast packet already. The router must
674 broadcast to inform other routers about changed ID.
676 * Added backpointer to server's router into SilcServer context in
677 silcd/server_internal.h.
679 * Fixed silc_server_packet_broadcast to send correct broadcast
682 * The channel key is now distributed to the local client as soon
683 as it is received from the router (in router environment) so that
684 no other packet may be sent for the channel until client has
687 * silc_server_remove_channel_user now broadcasts the received
688 Remove Channel User packet if it is not broadcast packet already.
689 The router must broadcast to inform other routers about removed
692 * Added users field into SilcPacketContext that is a reference count
693 of the context. One can increase the reference count by calling
694 silc_packet_context_dup which is now changed to just increase the
695 reference count instead of duplicating the data. The reference
696 count is decresed by calling silc_packet_context_free that will
697 free the data after the reference count hits zero.
699 For now on the packet context and everything allocated into it
700 (including the raw packet from network) must be freed by calling
701 the new silc_packet_context_free function. Added also new function
702 silc_packet_context_alloc that must be used now to allocate the
703 context. This also means that if a routine is asynchronous from
704 silc_[client/server]_packet_parse_type the packet context must
705 be duplicated by calling silc_packet_context_dup. Otherwise it
706 gets free'd after silc_[client/server]_packet_parse_type returns.
707 Also, one must remember that if packet is duplicated then its
708 reference count must be decresed by calling the free function as
709 many times as it was duplicated.
711 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
712 from both client and server.
714 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Made joining to a channel working in router environment.
718 * Cleaned up JOIN command on server side and create function
719 silc_server_command_join_channel internal routine to make the
722 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Changed silc_command_pending list to SilcDList. Also, added
725 `ident' field to SilcServerCommandPending structure to identify
726 the reply and to call correct callback.
728 Added silc_server_command_pending_check function to replace the
729 corresnponding macro. The silc_command_pending list is not
732 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
733 to set identifier to previously allocated Command Payload. It
734 is used to set identifier for command when resending Command
737 * Added silc_command_payload_encode_payload to encode Command
738 Payload buffer from SilcCommandPayload structure.
740 * Added silc_argument_payload_encode_payload to encode Argument
741 payload buffer from SilcArgumentPayload structure.
743 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Changed WHOIS command to support router connection on server side.
746 The whois request is always sent to router unless the server is
747 standalone server. After server has received the reply from the
748 router will it send the reply to the client.
750 * Added silc_server_packet_broadcast into silcd/server.[ch] to
751 broadcast received broadcast packet. The function is used only
752 by router. The broadcast packet is always sent to the router's
755 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
756 render given ID to printable string, for log files for example.
758 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Made basic router to router connections working. At least they
761 can now connect to each other but nothing really works the way
762 they are supposed - yet.
764 * Added new initiator token to RouterConnection configuration
765 file in silcd/serverconfig.[ch]. It is used to tell whether we
766 are the initiator to the remote router or whether we'll expect
767 the other end to connect.
769 * Moved registering of listener task to silc_server_init, hence
770 the server starts listenning as soon as it is run, even if it
771 does not have connections to other routers. Let's see how well
774 * Changed default connection retry timeouts for more suitable in
777 * Removed cipher and such arguments from silc_idlist_add_client
778 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
779 Added new function silc_idlist_add_data to add the keys and stuff
782 * Added SilcIDListData structure and added it to SilcClientEntry
783 and SilcServerEntry as their first field in the structure. This
784 way we can explicitly cast the ID entries to the SilcIDListData
785 structure and get common data for the entries. In past, we had
786 to first check what type of connection it is and then cast it to
787 correct ID entry type. Now, we can directly cast the opaque
788 pointer to the SilcIDListData (no matter what ID entry it actually
789 is) and get the data needed.
791 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Wow, found a bug in scheduler. The scheduler uninitialized itself
794 in some circumstances even if threre were timeout tasks, though not
795 IO tasks, but tasks anyway. Now fixed.
797 * Defined SilcServerConnection structure to hold connection specific
798 stuff about directly connected servers and routers. The definition
799 is currently in silcd/server_internal.h. I thought about having
800 a bit more important role fro this struct but for now it is used
801 only when connecting to other server (or router actually).
803 * Added connecting retry support in server when connecting to
804 router(s). The retry feature implement exponential backoff
805 algorithm. Also, added SilcServerParams structure to hold default
806 parameters for server. For now, it include these retry settings
807 and are hard coded. After server is moded to be as Silc Server
808 Library this structure will be more important.
810 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Changed client librarys channel->clients table to SilcList and
813 changed code accordingly.
815 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Changed client's channel table to SilcList and changed code
818 accordingly. Also changed SilcChannelClientEntry to include back-
819 pointer to the channel so that client entry can use that structure
820 as list as well and we have fast cross-reference to the channel.
821 This change dramatically decreased the complexity of channel
822 handling with client entry and vice versa (removed one extra
823 loop when searching for channel entry from many functions).
825 * Changed server->sim from table to SilcDList and changed code
828 * NAMES command can now be used from user interface. It will show
829 the user list on the channel, neatly.
831 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
832 Code now saves realname of the user if it becomes available.
834 * Renamed configure.in to configure.in.pre and made ./prepare
835 script to automatically add correct version string to
836 configure.in which it creates from configure.in.pre.
838 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * NAMES command reply now shows users mode with the nickname when
843 * Moved silc_client_ch[u]mode[_char] functions from
844 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
845 place sucks, they are utility functions and should be in some
848 * Fixed some unsigned int's to unsigned short's. Patch by cras.
850 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
853 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Added TRQ (efficient deque and list library) into lib/trq. This is
858 a very good list library that is currently used in the SILC. Defined
859 SilcList API over the library because I didn't like the API very
860 much. See lib/trq/silclist.h for the API and examples of how to
861 use the API. Fixed various places in the code to use the new
862 SilcList API. The SilcList is meant for lists that has a structure
863 already defined as a list. It is not suitable to add just some
864 context to the list (in TRQ, the context is the list actually).
866 So, I defined SilcDList that can be used for the purpose where
867 predefined list structure does not exit. This can be used as
868 such list. Now some context just can be added to the SilcDList.
869 Currently this list is not used in the SILC just yet, though there
870 are a lot places where this can replace dynamically allocated
871 tables and I will fix these places, later, to use SilcDList.
872 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
873 and use TRQ internally).
875 Also fixed some annoying warning messages that the original TRQ
876 code generated. Also minor changes to TRQ's Makefile.in.
878 * Added support for querying by Client ID to both WHOIS and
879 IDENTIFY commands into server, as required by the protocol.
881 * Removed method function pointers from SilcBuffer structure. They
882 weren't used to anything and just increased the context size for
883 no good reason. This change also made silc_buffer_alloc and
884 silc_buffer_free functions inline functions.
886 * Disabled command flooding detection support until it's fixed so
887 that it accepts commands in but does not execute them more than once
890 * Added silc_net_localhost(), to return local hostname, into
891 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
892 that must be initialized before calling silc_client_init.
894 * Added new function: silc_server_send_notify_on_channels to send
895 notify messages to all channels client has joined. It is assured
896 that the message is sent only once per client.
898 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
899 lib/silcutil/silcutil.[ch] as silc_format function. The new
900 function is generic and is used by server as well, not only by
901 the logging routines.
903 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
904 the provided version string was not acceptable. Added new function:
905 silc_ske_check_version into lib/silcske/silcske.h. The function
906 must be implemented by the application (client or server) and it
907 does not reside in the SKE library. The function checks the version
908 string remote end sent.
910 * Added back pointers (to opaque context and to SilcSocketConnection)
911 into SilcPacketContext structure into lib/silccore/silcpacket.h.
913 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
914 duplicate packet context structure.
916 * Changed `notify' client operation to send same arguments as client
917 receives from server except for ID's. ID's are mapped to correct
918 ID entry and that is returned. Also, if channel entry is not sent
919 by server but the notify is for channel the channel entry is sent
920 to application (otherwise application doesn't know that it is for
921 channel (library gets it from packet's Destination ID)).
923 * Added silc_client_remove_from_channels into client library to
924 remove a client from all channels it has joined to. Used when
925 received SIGNOFF notify from server. Added also new function
926 silc_client_replace_from_channels to replace old ID entry with
927 new ID entry on all channels. Used when received NICK_CHANGE
930 * Fixed ID Cache list handling in silc_idlist_get_client in
931 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
932 to get (or query) client by ID.
936 * Added connection authentication status message defined by the
937 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
938 support for these into the code in client and server side.
940 * Added generic function silc_client_send_command to send any command
941 with variable argument list. Application should use this function
942 to send commands if the command functions provided by the library
943 does not suite for the application's user interface needs.
945 * Added new `failure' client operation. Application is notified about
946 received failure packet if client is executing a protocol. In this
947 case the protocol's execution has failed.
949 * Added SKE's end notify to send the SKE_SUCCESS notify message that
950 is required by the protocol.
952 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
953 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
956 * Added status flag to SilcSKE object to indicate realtime status
959 * Application receives now exactly same command reply arguments as
960 the library receives from server. However, if ID is received the
961 corresponding ID entry is returned to the application (eg. Client
962 ID is mapped to correct SilcClientEntry entry and that is returned).
963 Changed command_reply client operation due to this change.
965 * Changed all ID's in commands and in command replys as ID Payloads.
966 Change affected both client and server side codes.
968 All ID's sent in SILC network (with execption of ID's in SILC
969 Packet header) are sent in ID Payload to support variable length
972 * Server now notifies nick changes and notifies all clients on
973 the channels about the new nickname (about the new Client ID,
976 * Implemented CMODE command to change channel modes. Supports all
977 channel modes defined by the protocol specs except ban and invite
978 lists. (Also, private channel key mode is supported but support for
979 setting private channel key in client is missing, thus, this mode
980 has no effect on client side (except that server requires that the
981 client uses private channel key and normal channel traffic does not
984 Also, invite mode works per se, but INVITE command does not work
985 yet correctly, so you can set channel as invite only channel but
986 inviting clients to the channel does not work (it is yet to be
987 thought what's the best way to do it).
989 * Added new command SILC_COMMAND_CUMODE to change user mode on the
990 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
991 Implemented CUMODE command to change user's mode on the channel.
992 Supports all modes defined by the protocol specs.
994 * Added NAMES command reply to return users modes on the channel.
996 * Removed unnecessary and slow ciphers from lib/silccrypt.
998 * Set SO_KEEPALIVE option to connection sockets by default.
1000 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1002 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1003 redefined the Notify Payload into protocol specs.
1005 * Added silc_id_payload_parse_id to get ID directly from raw
1008 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1011 accept searching by Client ID as well.
1013 * Added support for LEAVE and SIGNOFF notify types in client library.
1015 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1016 to parse ID Payload from raw data.
1018 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Added flags parameter into silc_ske_assemble_security_properties
1021 function in lib/silcske/silcske.[ch].
1023 * Changed notify client operation to fit better for notify messages
1024 sent by server. The notify payload received from server is now
1025 passed to the application (after parsing it to SilcNotifyPayload).
1026 It is application's responsibility to retrieve the arguments
1027 from the payload and show the message the way it wants. The message
1028 sent by server is implementation specific.
1030 * Changed public keys to comply with the protocol specification.
1031 Old public keys are not supported anymore and are not compatible.
1033 * Removed nickname from Channel Payload as the latest draft removed
1034 it. The client must resolve the nickname from the NAMES command
1035 reply received when it joined the channel.
1037 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1039 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Fixed some errors in protocol specification drafts.
1043 * Created lib/silccore/silcnotify.c to implement Notify Payload
1044 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1045 generic payloads described by protocol specifications. The file
1046 includes implementations for ID Payload and Argument Payload.
1048 * Changed Command Payload implementation to use the new Argument
1049 Payload. Changed command_xxxx_payload to command_payload_xxxx
1050 to comply with SILC coding conventions.
1052 * Added suppport for Argument Payload handling in Notify Payload
1053 implementation as protocol requires it. Added the new support
1054 into server and client lib as well.
1056 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Added support for multiple nicknames on same channel. [n] is
1059 added locally to the nickname if there are more than one same
1060 nicknames on the channel.
1062 * Server now sends all nicknames that matched WHOIS request.
1063 Client also shows the list received from server.
1065 * Added TOPIC command to client side. User can now set and show
1066 current topic on channel.
1068 * Added MOTD command to client and server. Also, server sends the
1069 motd when client connects to the server.
1071 * Changed version strings to comply ISO 8601.
1073 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Fixed protocol error handling in client library. It should now
1076 cope even if the SKE fails for some reason.
1078 * Made new protocol specification drafts for submitting to IETF.
1080 * Implemented TOPIC command to server in silcd/command.c.
1082 * Added two new notify types into lib/silccore/silcnotify.h:
1083 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1084 notify nickname change and topic setting/change on a channel.
1086 * API change of command_reply operation in client library. The
1087 application gets now the status type received from server as well.
1089 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1093 * Cras fixed and optimized the packet handling even further and
1094 it should work now. Minor change to the prototype of function
1095 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1097 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Added new function into lib/silcutil/silcschedule.[ch]:
1100 silc_schedule_with_fd to select() a specified fd. The function
1101 returns after timeout expires or data arrives or goes. The
1102 function is used by packet routines to wait that all data is
1103 received from network.
1105 * Fixed data reading from network in lib/silccore/silcpacket.c.
1106 The code now assures that all data is read from the fd and then
1107 continues packet processing. This was a bug fix since the code
1108 used to drop some data in some circumstances.
1110 * Added new function into lib/silcclient/client.[ch]:
1111 silc_client_start_key_exchange to start key exchange after
1112 connection has been established to server. The code internally
1113 now uses this funtion but its main purpose was to provide it
1114 for applications that perform their own connecting. After
1115 application has created a connection it merely calls this
1116 function to start the key exchange between client and server.
1117 The library takes care of everything else after that.
1119 Updated also lib/silcclient/README to explain the usage of
1122 * Do not send to application information that connection has
1123 been established. Application gets notified it by connect
1126 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Applied cras's patch to add silc_schedule_one function. The
1129 function runs scheduler once and returns.
1131 * Fixed the scheduler after cras messed it up. The timeout
1132 handling works now as it's supposed to work.
1134 * Added into lib/silccore/ silcnotify.h to include notify
1135 message types support. Changed silc_server_send_notify*
1136 functions, in server.[ch], to support those new notify types.
1137 Added the support for the notify types into client library,
1138 as well. Added new notify client operation into ops.h in
1141 * Changed silc_server_packet_send_to_channel to send normal
1142 packets instead of just channel message packets. The function
1143 is now used to send the notify packets to channels. It is not
1144 used to send channel message packets anymore, as server never
1147 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1148 va_arg()s as it seems to require it nowadays. I guess, if SILC
1149 is compiled with older va_arg() the new code should work anyway.
1151 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Splitted core library. Core library (lib/silccore) includes
1154 now only SILC protocol specific core (and common) components.
1155 Created new utility library (lib/silcutil) that includes more
1156 generic purpose stuff. The stuff for util library was taken
1157 from the old core library. This was minor and easy split.
1159 * Created SILC Client Library (lib/silcclient) that includes
1160 implementation of the SILC client without user interface. This
1161 was major move from silc/ directory. The code has been changed
1162 so that it is transparent towards the user interface. The
1163 silc/ directory includes now the same user interface as before
1164 and it uses the new client library. Read lib/silcclient/README.
1165 Basicly, the client library performs everything else related
1166 to SILC except user interface handling. Also, configuration
1167 files are considered to be part of user interface and library
1168 does not handle them.
1170 This change also changed a lot of structures, function naming etc.
1171 Most important change was that SilcClientWindow object was
1172 renamed to SilcClientConnection in the client library. Created
1173 also new file lib/silcclient/ops.h. Also added new files
1174 silc/local_command.[ch] and silc/client_ops.[ch].
1176 All these changes were made to make it easier for user interface
1177 designers to create what ever user interface for the SILC client
1180 It is also expected that the server will be moved to lib
1181 directory as well and SILC Server Library will be created;
1182 sometimes in the future.
1184 * Removed Local commands from lib/silccore/silccommand.h as
1185 they are application specific and new client library does not
1186 handle any of those anymore.
1188 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1189 old client implementation in silc/.
1191 * Added support for callback functions in SILC_LOG_* macros.
1192 Application can now set its own callbacks that will be called
1193 instead of using the default functions that will always print
1194 the debug messages to stderr (or stdout). Also, debugging can
1195 now be disabled by setting silc_debug to FALSE and re-enabled by
1196 setting it to TRUE. Note, that logging will still work even
1197 if debugging is disabled.
1199 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1200 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1201 silc_log_reset_debug_callbacks.
1203 * To enable debugging in silc client one must give now -d
1204 option on command line.
1206 * Changed silc_schedule_init to automatically allocate task queues
1207 if they are not allocated before calling it.
1209 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1211 * Added GMP 3.1 into math library.
1213 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1216 a channel in SILC network. The packet is used by servers and
1217 routers to notify other routers that user has left a channel.
1218 This little feature was missing until now. Added the feature
1219 to protocol specification as well.
1221 Added functions: silc_server_send_remove_channel_user and
1222 silc_server_remove_channel_user into server.[ch].
1224 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1225 lib/silccore/silcpacket.h. However, they are not implemented
1228 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Fixed joining to a channel and sending channel messages
1231 between server and router. The channel message sending should
1232 now work inside a cell.
1234 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Fixed the private message sending between server and router.
1237 The private message sending should now work inside a cell.
1239 * Added silc_server_replace_id into server.[ch] to replace
1240 existing ID in the SILC network.
1242 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1243 and silc_idlist_replace_server_id into idlist.[ch] in server.
1245 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Fixed the server to server connections. Server can again now
1248 connect to router. Router to router connections probably does
1251 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Added dynamic protocol registering support. Now protocols can
1254 registered and unregistered on the fly. Patch by cras.
1256 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added lib/contrib directory to hold routines that some platforms
1259 don't have but are needed by SILC.
1261 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1262 into lin/contrib to provide getopt() and getopt_long() for
1263 those who don't have it.
1265 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Added AWAY command to client. When away message is set and
1268 client receives a private message packet the client automatically
1269 replies to the sender with the away message.
1271 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1272 bug seemed to be the cause of recent problems when compiling
1275 * Added version detection support to SKE protocol specification
1276 and added the new changes to the SKE implementation as well.
1277 There were other minor changes in the SKE protocol as well.
1279 Many changes in lib/silcske/silcske.[ch] and in
1280 lib/silcske/payload.[ch].
1282 * Added ^U functionality, clear input line. Patch from cras.
1284 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Mainly small bugfixes on core library. Fixed some debugging
1287 logging and buffer overflow in silclog.c.
1289 * Updated config.sub and config.guess on the distribution tree.
1291 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1293 * Added command lagging support in server. Client may execute
1294 commands now only once in two seconds.
1296 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Optimized packet reception. MAC computation and checking is now
1299 also more optimized. A lot previously duplicated code is now
1300 used as generic by both client and server.
1302 * Fixed key pair generation in clientutil.c
1304 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Added into lib/silccore/silcbufutil.[ch] new function;
1307 silc_buffer_realloc.
1309 * Moved generic packet sending/encryption functions to
1310 lib/silccore/silcpacket.[ch] from client and server. Some
1311 rewriting of the functions.
1313 * Moved all generic packet reception/decryption functions to
1314 lib/silccore/silcpacket.[ch] from client and server. The
1315 packet processing is now much cleaner in both client and server.
1316 These were major changes in both client and server.
1318 * Created many common functions in server to do packet sending.
1319 Previously code were duplicated a lot, this has been removed
1322 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Rewrote major parts of the ID cache system. Don't know
1325 whether it is better now or not but at least the API is more
1328 * Major rewrite on ID cache stuff on client because of the ID
1329 cache API changes. Added idlist.c to client.
1331 * Also major rewrite on ID cache stuff on server as well.
1332 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1333 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1334 in hand, instead they are all put into the ID cache system now.
1335 All server_idlist_* routines uses ID cache now instead of
1336 traversing its own lists (those lists does not exist anymore).
1337 SilcIDList though still exists. Also, SilcXXXEntry's are
1340 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Finally made the SKE implementation compliant to the protocol
1343 specification. All mp integers are now binary encoded as
1344 opposed being HEX encoded.
1346 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1349 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1350 functions: silc_[encode/decode]_pem. Also added function
1351 silc_encode_pem_file to PEM encode with newlines ('\n') for
1354 * SILC public keys are now encoded either PEM or binary. Same
1355 option is for private keys as well. By default private keys
1356 are binary encoded and public keys PEM encoded. Silly HEX
1357 encoding were removed.
1359 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1360 function to create fingerprints.
1362 * Fixed a bug in SHA1; does not change the original data anymore.
1364 * Partly implemented INFO command on client and server side.
1365 Fixed CLEAR command. Changes to SERVER command; show current
1366 server(s) when giving command without arguments. Added
1367 VERSION command to client.
1369 * Added check to server that unregistered connections cannot
1370 execute commands (unless it is specificly allowed).
1372 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Fixed screen refresh.
1376 * Fixed channel joining bug from client. On some circumstances
1377 client tried to join to a channel it had already joined.
1379 * Added public key verification process into client's protocol.c.
1380 The client now verifies the public key from user and saves
1381 it into ~./silc/serverkeys/ directory.
1383 Added into: clientutil.[ch]: silc_client_verify_server_key.
1385 * Changed SKE protocol's silc_ske_initiator_finish function
1386 to accept callback function that verifies the received public
1387 key. Removed old silc_ske_verify_public_key function.
1389 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1391 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1392 silc_pkcs_private_key[_data]_set.
1394 * Made the password and public authentication more cleaner in
1395 server's protocol.c.
1397 * Removed historic and obsolete protocol `channel_auth' from
1398 both client and server.
1400 * Removed wrong way of sending command status messages from
1401 server to client in server's command.c. The old way violated
1402 protocol specification.
1404 Changes to silccore/silccommand.[ch]: removed
1405 silc_command_encode_status_payload -> not needed anymore,
1406 changed silc_command_encode_payload_va to accept extra
1407 argument on variable argument list. The argument type must
1408 now be provided to the function. Also, added new function:
1409 silc_command_encode_reply_payload_va which is same as
1410 normal command_encode_payload_va except command status type
1411 is provided as extra argument.
1413 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Added ~./silc directory handling. The directory includes the
1416 public and private keys for the client.
1418 Added silc_client_check_silc_dir, silc_client_create_identifier
1419 and silc_client_load_keys.
1421 * Implemented SILC protocol compliant public key. Added public
1422 and private key saving to and loading from files.
1424 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1425 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1426 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1427 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1428 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1430 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1431 silc_pkcs_load_[public/private]_key.
1433 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added silc_server_get_route (route.[ch]) to get connection
1436 data for the fastest route for given ID.
1438 * Implemented INVITE command on client and server. The command
1439 were re-defined in the SILC Protocol Specification and the
1440 implementation now complies with the specification.
1442 * Implemented PING command on client and server.
1444 * Implemented NAMES command on client and server. The server side
1445 supports currently only normal server not router server yet.
1446 Some changes to NAMES definition in SILC protocol specification.
1448 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Implemented LEAVE command on client and server.
1452 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1453 again. This change was made to the protocol as well. Server
1454 should not violate the protocol specification anymore.
1456 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1459 was tested. SOCKS4 was not but should work anyway.
