1 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * The RSA key length is now save to the RsaKey context in the
4 key generation process in lib/silccrypt/rsa.c. The key length
5 is now used to figure out the maximum size of the block allowed
6 to be encrypted/signed.
8 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
9 is equivalent to the silc_mp_mp2bin but does not allocate any
12 * Changed silc_mp_mp2bin API to take length argument. If it is
13 non-zero then the buffer is allocated that large. If zero, then
14 the size is approximated using silc_mp_sizeinbase, which however
17 * Created Global RNG API which is global RNG that application can
18 initialize. After initializing, any routine anywhere in the
19 code (including library) can use RNG without allocating a new
20 RNG object. This was done to allow this sort of use of the
21 RNG in code that has no chance to allocate RNG object. All
22 applications currently allocate this and many routines in the
23 library use this. Affected file lib/silccrypt/silcrng.[ch].
25 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
26 it to use the Global RNG API.
28 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * The client entry's userinfo pointer must be always valid.
31 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
32 will fail since it requires the userinfo. Now, the userinfo
33 is allocated as "" if actual userinfo does not exist. Actually,
34 it must exist and it is totally Ok to drop client connections
35 that does not announce the userinfo. However, we will make
36 this workaround for now.
38 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
39 to return the remote port by socket.
41 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
43 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
44 SILC_SERVER_PENDING_EXEC and added an new macro
45 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
46 data or when error occurs while processing the pending command.
48 Added new argument `destructor' into silc_server_command_pending
49 and to the SilcServerCommandPending object. This destructor is
50 now called after calling the pending callback or if error occurs
51 immediately. If error occurs the actual pending callback won't
52 be called at all - only the destructor. The destructor may be
53 NULL if destructor is not needed.
55 All this applies for client library code as well. Similar
56 changes were made there as well for the pending commands.
58 In the client, the application must now allocate the
59 SilcClientCommandContext with the silc_client_command_alloc
62 * Added reference counter to the SilcServerCommandContext. Added
63 function silc_server_command_alloc and silc_server_command_dup
66 Same type of functions added to the client library for the same
69 * Removed the cmd_ident from IDListData away since it is now
70 global for all connections. It is the command identifier used
71 in command sending and with pending commands. The affected file
74 * Added reference counter to the SilcSocketConnection objecet to
75 indicate the usage count of the object. The object won't be
76 freed untill the reference counter hits zero. Currently only
77 server uses this, and client ignores it. The client must be
78 set to use this too later. The affected files are
79 lib/silccore/silcsockconn.[ch]. Added also the function
80 silc_socket_dup to increase the reference counter.
82 This was mainly added because it is possible that the socket
83 is removed underneath of pending command or other async
84 operation. Now it won't be free'd and proper DISCONNECTING
85 flags, etc. can be set to avoid sending data to connection that
88 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
89 the connection. After that it sets SILC_SET_DISCONNECTED.
90 It is, however, possible that the socket data is not still freed.
91 The silc_server_packet_process now checks that data is not
92 read or written to connection that is DISCONNECTED. The socket
93 get's freed when the reference counter hits zero.
95 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Changed the client operation API: channel_message operation's
98 `sender' is now the client entry of the sender, not the nickname
99 and the `channel' is the channel entry, not the channel name.
101 In the private_message operation the `sender' is now also the
102 client entry of the sender not the nickname.
104 Affected file is lib/silcclient/ops.h and all applications
105 using the client operations.
107 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Moved the calling of ops->connect() from connect_to_server_final
110 into receive_new_id functin since that is the point when the
111 client is actually allowed to send traffic to network. The
112 affected file is lib/silcclient/client.c.
114 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
117 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
118 (if needs broadcasting) instead of broadcasting the packets one
119 by one which would make a burst in the network traffic.
121 * Added `broadcast' argument to the functions in silcd/server.[ch]
122 silc_server_create_new_channel[_with_id] to indicate whether
123 to send New Channel packet to primary router.
125 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Added new function into the silcd/server.[ch] files:
128 silc_server_create_new_channel_with_id to create new channel with
129 already existing Channel ID.
131 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
132 lib/silccore/silcpacket.h. This packet is used t send list of
133 Set Mode payloads inside one packet. Server uses this to set
134 the modes for the channels and clients on those channels, that it
135 announced to the router when it connected to it. The protocol
136 specification has been updated accordingly.
138 * The silc_server_new_channel did not handle the packet coming
139 from normal server as it normally does not send that. However,
140 when it announces its channels it does send it. Implemented
141 the support for that.
143 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
144 into the file lib/silccore/id.h.
146 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed memory leaks in the functions silc_idlist_del_client,
149 silc_idlist_del_channel and silc_idlist_del_server in the file
150 silcd/idlist.c. All of those leaked like a sieve.
152 * Fixed some small memory leaks in the client's function
153 silc_client_notify_by_server.
155 * Added functions into silcd/server.c: silc_server_announce_clients,
156 silc_server_announce_channels and silc_server_announce_server.
157 These functions are used by normal and router server to announce
158 to its primary router about clients, channels and servers (when
159 router) that we own. This is done after we've connected to the
162 These functions effectively implements the following packet types:
163 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
164 and SILC_PACKET_NEW_ID_LIST.
166 * Added new functions into the silcd/packet_receive.[ch]:
167 silc_server_new_id_list, silc_server_new_channel_list and
168 silc_server_new_channel_user_list to handle the incoming
169 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
171 * Added support of changing Channel ID in the function
172 silc_server_replace_id. If the server that announces a channel
173 to the router already exists in the router (with same name but
174 with different Channel ID), router is responsible to send
175 Replace ID packet to the server and force the server to change
176 the Channel ID to the one router has.
178 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
179 client that the Channel ID has been changed by the router. The
180 normal server sends this to the client. Client must start using
181 the new Channel ID as the channel's ID.
183 Implemented handling of this new type into lib/silcclient/client.c
184 into the function silc_client_notify_by_server.
186 * Added new function silc_idlist_replace_channel_id into the files
187 silcd/idlist.[ch] to replace the Channel ID.
189 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Call silc_server_command_identify_check always when processing
192 the IDENTIFY command in silcd/command.c
194 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
197 send keepalive packets. The packet can be sent by clients,
200 Added function silc_socket_set_heartbeat into the file
201 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
202 If not set, the heartbeat is not performed. The actual
203 heartbeat is implemented in the low level socket connection
204 library. However, application is responsible of actually
207 Added silc_server_send_heartbeat to send the actual heartbeat
208 packet into silcd/packet_send.[ch]. Server now performs
209 keepalive with all connections.
211 * Added silc_task_get_first function into lib/silcutil/silctask.c
212 to return the timeout task with shortest timeout. There was a bug
213 in task unregistration that caused problems. TODO has been
214 updated to include that task system must be rewritten.
216 * The client library will now resolve the client information when
217 receiving JOIN notify from server for client that we know but
218 have incomplete information.
220 * Rewrote parts of silc_server_remove_from_channels and
221 silc_server_remove_from_one_channel as they did not remove the
222 channel in some circumstances even though they should've.
224 * Encryption problem encountered in server:
226 The LEAVE command used to send the Channel Key packet to the
227 router immediately after generating it. However, the code
228 had earlier sent Remove Channel user packet but not immediately,
229 ie. it was put to queue. The order of packets in the router
230 was that Channel Key packet was first and Remove Channel User
231 packet was second, even though they were encrypted in the
232 reverse order. For this reason, MAC check failed. Now, this
233 is fixed by not sending the Channel Key packet immediately but
234 putting it to queue. However, this is more fundamental problem:
235 packets that are in queue should actually not be encrypted
236 because packets that are sent immediately gets encrypted
237 actually with wrong IV (and thus MAC check fails). So, packets
238 that are in queue should be encrypted when they are sent to
239 the wire and not when they put to the queue.
241 However, the problem is that the current system has not been
242 designed to work that way. Instead, the packet is encrypted
243 as soon as possible and left to the queue. The queue is then
244 just purged into wire. There won't be any fixes for this
245 any time soon. So, the current semantic for packet sending
248 o If you send packet to remote host and do not force the send
249 (the packet will be in queue) then all subsequent packets to the
250 same remote host must also be put to the queue. Only after the
251 queue has been purged is it safe again to force the packet
254 o If you send all packets immediately then it safe to send
255 any of subsequent packets through the queue, however, after
256 the first packet is put to queue then any subsequent packets
257 must also be put to the queue.
259 Follow these rules and everything works fine.
261 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Added new function silc_server_remove_clients_by_server to
264 remove all client entries from ID list when the server connection
265 is lost. In this case it is also important to invalidate all
266 client entires as they hold the invalid server entry. This
267 fixes fatal bug when server has lost connection and will reconnect
270 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Made some sanity checks to silc_server_daemonise like to check
273 whether the requested user and group actually exists.
275 * Added sanity check to SKE's silc_ske_responder_finish to check
276 that the public and private key actually is valid.
278 * Invalidate the client's nickname when receiving Replace ID
279 packet and the Client ID is being replaced. This means that the
280 server will query the nickname if someone needs it (client)
283 * Sort the ID Cache in client library when the ID Cache data
284 has changed (needs sorting).
286 * Do not allow for SILC client to create several connections to
287 several servers. The client does not support windows right now
288 and generating multiple connections causes weird behaviour.
290 Irssi-silc client does support windows and can handle several
291 connections without problems, see: www.irssi.org and SILC plugin.
293 * Fixed some places where client was added to the IDList. The
294 rule of thumb is following (in order to get everything right):
295 If the client is directly connected local client then the
296 `connection' argument must be set and `router' argument must be
297 NULL to silc_idlist_add_client function. If the client is not
298 directly connected client then the `router' argument must
299 bet set and the `connection' argument must be NULL to the
300 silc_idlist_add_client function.
302 * The funtion silc_server_packet_send_local_channel actually did
303 not check whether the client was locally connected or not. It
304 does that now. Fixed a bug related to LEAVE command.
306 * Fixed Remove Channel User payload parsing bug in server's
307 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
309 * The server's silc_server_save_channel_key now checks also the
310 global ID list for the channel as it might not be in the local
311 list. Fixed a bug related to LEAVE command.
313 * Is this the end of the [<unknown>] buglet that has been lurking
314 around for a long time? A little for loop fix in server's
315 silc_server_command_whois_parse that is used by both IDENTIFY
316 and WHOIS command. At least, this was a clear bug and a cause
317 of one type of [<unknown>] buglet.
319 * WHOIS and IDENTIFY commands call the function
320 silc_server_command_[whois/identify]_check function even if
321 we are not router server.
323 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * Added --with-gmp configuration option. If set the GMP
326 is always compiled in the SILC source tree. If not set then
327 it is checked whether the system has the GMP3 installed. If
328 it has then the GMP won't be compiled (the system's headers
329 and library is used), if it doesn't have it then the GMP is
330 compiled in the SILC source tree.
332 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Changed RSA private exponent generation to what PKCS #1
335 suggests. We try to find the smallest possible d by doing
336 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
337 not security fix but optimization.
339 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Added new config entry [Identity] to fork the server and run
342 it as specific user and group. A patch from Bostik.
344 * Imported Dotconf configuration library into lib/dotconf.
345 This will be used to create the SILC configuration files later.
346 It will appear in the distsribution after this commit.
348 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
350 * A big code auditing weekend happening. Auditing code for
351 obvious mistakes, bugs and errors. Also, removing any code
354 Removed files for being obsolete:
356 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
357 inline in the file lib/silcutil/silcbuffer.h)
359 o lib/silcutil/silcbufutil.c (the header has inline versions)
361 Changed code to fix possible error conditions:
363 o The buffer formatting routines now check that the destination
364 buffer really has enough space to add the data. This applies for
365 both buffer formatting and unformatting
366 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
367 unformatting was changed to accomodate following rules:
368 XXX_*STRING_ALLOC will allocate space for the data into the pointer
369 sent to the function while XXX_*STRING will not allocate or copy
370 the data into the buffer. Instead it sets the pointer from the
371 buffer into the pointer sent as argument (XXX_*STRING used to
372 require that the pointer must be allocated already). This change
373 makes this whole thing a bit more consistent and more optimized
374 (note that the data returned in the unformatting with XXX_*STRING
375 must not be freed now). The routines return now -1 on error.
377 o Tried to find all code that use buffer_format and buffer_unformat
378 and added return value checking to prevent formatting and
379 especially unformatting errors and possible subsequent fatal
382 o Changed ske->x and ske->KEY to mallocated pointers in
383 lib/silcske/silcske.h. Fixed possible data and memory leak.
385 o Added return value checking to all *_parse* functions. Fixed
386 many memory leaks as well.
388 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
389 so that buffer overflows would not happen. All code now also
390 checks the return value as it can fail.
392 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Added reconnection support to server if the normal server looses
395 its connection to the router (for example if router is rebooted).
396 The server performs normal reconnection strategy implemented
397 to the server. Affected file silcd/server.c.
399 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
401 * Added new packet type SILC_PACKET_SET_MODE that is used to
402 distribute the information about changed modes (for clients,
403 channels and clients channel modes) to all routers in the
404 network. Updated the protocol specification accordingly.
406 Added functions into silcd/packet_send.c and
407 silcd/packet_receive.c: silc_server_send_set_mode,
408 silc_server_set_mode.
410 Added new files silcmode.[ch] into lib/silccore that implements
411 the encoding and decoding of Set Mode Payload. Added new type
412 SilcSetModePayload. Moved the definitions of different modes
413 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
415 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Oops, a little mistake in server's connection authentication
418 protocol. The protocol is not ended with FAILURE but with
419 SUCCESS if the authentication is Ok. :) Affected file is
422 * Implemented NICK_CHANGE notify handling in server in the file
423 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
424 the local clients on the channel. After the changing nickname
425 in router environment snhould work and the [<unknown>] nickname
426 should appear no more.
428 The silc_server_replace_id function that receives the Replace ID
429 payload now sends the NICK_CHANGE notify type also in the file
430 silcd/packet_receive.c
432 * Changed WHOIS and IDENTIFY command to support the maximum amount
433 of arguments defined in protocol specs (3328 arguments). This
434 fixed a bug that caused problems when there were more than three
437 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Added extra parameter, command identifier, to the
440 silc_client_send_command so that explicit command identifier
443 Changed that ID list routines uses specific command identifier
444 when sending WHOIS/IDENTIFY requests to the server so that they
445 can be identified when the reply comes back.
447 Affected files lib/silcclient/command.[ch],
448 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
450 * Added `sender' argument to silc_server_packet_send_to_channel
451 to indicaet the sender who originally sent the packet to us
452 that we are now re-sending. Ignored if NULL. Affected file
453 silcd/packet_send.[ch].
455 * Added some server statistics support in silcd/server_internal.h
456 SilcServerStatistics structure and around the server code. Also
457 send some nice statistics information when client is connecting
460 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Fixed channel ID decoding in server's JOIN command reply in
463 silcd/command_reply.c
465 * Fixed braodcasting of replace ID payload to not to send it if
466 we are standalone server in silcd/packet_receive.c.
468 * Fixed all channel message sending routines to not to send
469 packets to clients that has router set, since they are routed
470 separately in the same function earlier. Affects file
471 silcd/packet_send.c and all channel packet sending functions.
473 * In USERS reply, res_argv[i] are not allocated, the table
474 is allocated. Thus changed that free the table, not its
477 * In server's whois_check and identify_check if the client is
478 locally connected do not send any WHOIS commands - they are not
481 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Fixed some minor bugs in client when sending WHOIS command. The
484 arguments was in wrong order.
486 * Removed statis function add_to_channel from server in
487 silcd/command.c that was previously used with the joining but
490 * Tested USERS command in router environment successfully with two
491 routers, two servers and two clients.
493 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
495 * Reorganized the USERS command and command reply in client library
496 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
497 When the command is given by user we register a pending command
498 callback that will reprocess the command after the reply has been
499 received from the server. When reprocessing the packet we then
500 display the information. Thus, the USERS information is displayed
501 now in the command callback instead of in the command reply
502 callback. The processing of the command is same as previously
503 when server has sent the command reply in the JOINing process.
505 * Added to USERS command in silcd/command_reply.c to join the client,
506 we didn't use to know about, to the channel after we've created
507 a client entry for it. Also, for clienet we did know already still
508 check whether it is on the channel or not and add it if not.
510 * Removed silc_server_command_join_notify as the function and its
513 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Changed the client's pending command handling to the same as the
516 server's pending command handling. It is also now possible to
517 execute command reply functions from other command reply
518 function as the function callbacks for commands and command
519 replies are one and same. The pending commands are not static
520 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
521 in client connection context. Thus, pending commands are server
522 connection specific as it is convenient.
524 Changed the function silc_client_command_pending and
525 silc_client_command_pending_del and added new function
526 silc_client_command_pending_check. Removed the
527 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
530 * Added cmd_ident, current command identifier, to the client
531 connection context in lib/silcclient/client.h to keep track on
532 command identifiers used in command sending. Client's command reply
533 function handling now supports the mandatory command identifiers.
535 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
536 funtions in client to fully support pending command callbacks.
538 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
539 as one of the arguments to the application in the command reply
542 * NOTE: The FORWARDED flag is depracated. It used to be depracated
543 before first releasing SILC but came back. Now it is removed again
544 and should come back nomore. The FORWARDED flag was used only
545 by the JOINing procedure by forwarding the command packet to router.
546 Now, the JOINing procedure has been changed to more generic (due
547 to various router environment issues) and FORWARDED is not needed
548 anymore for anything. The protocol specification is yet to be
551 Now, removed silc_server_packet_forward from server and the flag
552 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
554 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Renamed NAMES command to USERS command. The NAMES was named that
557 due to historical reasons. Now it is renamed. Also, rewrote
558 parts of the USERS command. The nickname list is not sent anymore
559 by the server. Only Client ID and mode lists are sent in the USERS
560 command. Changed this also to the protocol specification.
562 The client now resolves the names and stuff after it receives
563 the USERS list from the server when joining to the channel.
565 * WHOIS and IDENTIFY commands has been changed to support multiple
566 Client ID's per command. One can now search for multiple users
567 in the network by sending only one WHOIS or IDENTIFY command.
568 Changed the code and the protocol specifications.
570 * Removed silc_server_command_identify_parse and changed that IDENTIFY
571 uses silc_server_command_whois_parse to parse the request. */
573 * If normal server, do not parse the WHOIS and IDENTIFY requests
574 before sending it to the router. Saves some time.
576 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Fixed JOIN command on client library. Wrong number of arguments
579 used to crash the client.
581 * Added silc_server_channel_has_global function to check whether
582 channel has global users or not.
584 * Added silc_server_channel_has_local function to check whether channel
585 has locally connected clients on the channel.
587 * The silc_server_remove_from_one_channel now checks whether the
588 channel has global users or not after given client was removed from
589 the channel. It also checks whether the channel has local clients
590 on the channel anymore. If it does not have then the channel entry
591 is removed as it is not needed anymore.
593 * The silc_server_notify now checks on JOIN notify whether the joining
594 client is one of locally connected or global. If it is global then
595 the channel has now global users on the channel and that is marked
596 to the channel entry. Also, it now saves the global client to
597 global list who is joining and JOINs it to the channel. This is
598 for normal server, that is.
600 Changed silc_server_send_notify_on_channel,
601 silc_server_packet_relay_to_channel and
602 silc_server_packet_send_to_channel check if we are normal server
603 and client has router set (ie. global client) do not send the
604 message to that client, as it is already routed to our router.
606 * Implemented LEAVE notify type handling in silc_server_notify
609 * Tested LEAVE command in router environment successfully. Tested
610 with two routers, two servers and two clients.
614 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
616 * Implemented SIGNOFF notify type handling in silc_server_notify
619 * silc_server_remove_id now removes the client entry from all channels
620 it has joined and thusly sends SIGNOFF notify type.
622 * Rewrote the NAMES list generation in server by removing two excess
623 loops. The lists are created now inside one loop.
625 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * silc_server_remove_channel_user checks now also global list
628 for channel and client.
630 * silc_server_new_channel_user checks now both local and global
631 list for channel and client. Fixed a bug in client id decoding.
632 Used to decode wrong buffer.
634 * silc_server_channel_message checks now both local and global
635 list for channel entry.
637 * Tested channel joining (hence JOIN) in router environment
638 successfully. Tested with two routers, two servers and two
641 * Tested channel message sending in router environment successfully.
643 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * Added silc_server_save_channel_key into server.[ch] to save the
646 received channel key in Channel Key payload processing. It is
647 also used in JOIN command reply handling.
649 Equivalent function silc_client_save_channel_key added into
650 client.[ch] into client library.
652 * Changed JOIN command reply to send information whether the channel
653 was created or not (is existing already) and the channel key
654 payload. Changed protocol specs accordingly.
656 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
657 the request was sent by ID and not by nickname. Crashed on
660 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
663 now correctly save the received data.
665 * silc_server_free_sock_user_data now notifies routers in the
666 network about entities leaving the network.
668 At the same time implemented functions silc_server_remove_id
669 and silc_server_send_remove_id to receive and send REMOVE_ID
670 packets. The packet is used to notify routers in the network
671 about leaving entities. The ID removed will become invalid in
674 * Added function silc_idlist_del_server into server. Removes and
675 free's server entry from ID list.
677 * silc_server_private_message function now checks, if we are router,
678 that the destination ID really is valid ID, naturally.
680 * In router when NEW_ID packet is received (for new client) the
681 hash of the Client ID is saved in the ID Cache but the
682 client->nickname is set to NULL, instead of putting the hash
685 IDENTIFY command now also checks that client->nickname must be
686 valid. If it is not if will request the data from the server who
687 owns the client. Added new function
688 silc_server_command_identify_check.
690 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
691 to set the command to already allocated Command Payload.
693 * Tested private message sending in router environment with two
694 routers, two servers and two clients. Fixed minor bugs and now
697 * Fixed segfault from client's NAMES command. Used to crash if
700 * Forwarded packets must not be routed even if it is not destined
701 to the receiver. Changed server code comply with this.
703 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Added `require_reverse_mapping' boolean value to ServerParams
706 structure. If TRUE (not default) the server will require that
707 the connecting host has fully qualified domain name.
709 If the reverse mapping is not required and hostname could not be
710 found the IP address is used as hostname.
712 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Implemented version string checking to both client and server.
715 The check is incomplete currently due to the abnormal version
716 strings used in development version of SILC.
718 * Changed all command functions in server to use the new
721 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
723 * Changed char *data to unsigned char *data in ID Cache system to
724 support binary data as ID Cache data. Changed code to support
725 binary data in lib/silccore/idcache.c.
727 * Renamed silc_server_packet_relay_command_reply to
728 silc_server_command_reply as it is normal packet receiving
729 function. Rewrote the function to accept command replys for
730 servers and not only for clients.
732 * Mark remote router always as registered server if we are connecting
733 to it. Otherwise, commands sent by the router to us are ignored.
735 * All ID List find routines now returns the ID Cache Entry pointer
736 as well if requested.
738 * WHOIS command works now in router environment, tested with two
739 routers, two servers and two clients.
741 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
742 in router environment (as it is almost equivalent to WHOIS) but
743 hasn't been tested thoroughly. Added new functions:
745 silc_server_command_identify_parse
746 silc_server_command_identify_send_reply
747 silc_server_command_identify_from_client
748 silc_server_command_identify_from_server
750 * Disabled route cache adding because adding two different ID's with
751 same IP replaces the old cache entry thus giving wrong route.
752 The entry->router->connection is always the fastest route anyway
753 so route cache may not be needed. Of course, new routes maybe
754 established after receiving the ID when the entry->router->connection
755 might not be anymore the most optimal.
757 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Add route cache for received ID for fast routing.
761 * Added silc_server_packet_route to route received packet on router
762 that is not destined to us.
764 * Renamed silc_server_get_route to silc_server_route_get.
766 * Added id_string and id_string_len fields into SilcServer to
767 include encoded ServerID for fast comparing without excess
768 encoding of the ID's.
770 * Cleaned up WHOIS command on server side. Added following static
773 silc_server_command_whois_parse
774 silc_server_command_whois_check
775 silc_server_command_whois_send_reply
776 silc_server_command_whois_from_client
777 silc_server_command_whois_from_server
779 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
780 arguments in command replies. All command functions should be
781 updated to use this macro.
783 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Minor typo fixes on command reply handling on server.
787 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Added silc_server_command_add_to_channel internal routine to add
790 the client to the channel after router has created the channel and
791 sent command reply to the server.
793 * Added generic silc_server_send_command to send any command from
796 * Use static buffer with ID rendering instead of duplicating data.
798 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Fixed a channel user mode bug when joining to a channel server gave
801 everybody channel founder rights, oops.
803 * We mark ourselves as the router of the incoming server connection
804 if we are router ourselves. This way we can check in some packet
805 sending functions whether it is locally connected server. For
806 incoming router connections we put NULL.
808 * For router sending packets locally means now always sending the
809 packet cell wide; to local clients and local servers. For normal
810 server sending packet locally means sending it to only local
813 * Fixed the JOIN command to really work in router environment. If the
814 channel is created it is always created by the router. Router is
815 also responsible of making the initial joining to the channel,
816 sending JOIN notify to the sending server and distributing
817 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
818 does not exist server doesn't do anything else but forward the
819 command to the router which performs everything.
821 * Added silc_server_send_channel_key function to send the Channel Key
824 * Added silc_server_create_channel_key to create new channel key. The
825 channel key is now re-generated everytime someone joins or leaves
826 a channel, as protocol dictates. Note: channel->key_len is the
829 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Splitted server.[ch] finally. Created now packet_send.[ch] and
832 packet_receive.[ch] to separate packet sending and receiving
833 routines. The server.[ch] now includes everything else including
834 actual packet processing (writing and reading data) and other
837 Renamed silc_server_private_message_send_internal to
838 silc_server_send_private_message. The routine is still though
839 used only to relay private messages as server does not send
840 private messages itself.
842 Renamed silc_server_new_channel to silc_server_create_new_channel
843 and added new function sicl_server_new_channel that handles the
844 incoming New Channel packet. Added also new sending function
845 silc_server_send_new_channel to send New Channel Payload.
847 * Added new function silc_server_notify to process incoming notify
848 packet to the server/router. Server may then relay the notify
849 to clients if needed.
851 * Added new function silc_server_new_channel_user to process incoming
852 New Channel User packet. Router will redistribute the packet and
853 send JOIN notify to its local clients and locally connected servers
854 if needed. Normal server will send JOIN notify to its local client
855 on same channel when received this packet. Added also corresponding
856 sending function silc_server_send_new_channel_user to sent the
859 * Added boolean route argument to send_notif_to_channel and
860 packet_send_to_channel functions to attempt to route the packet
861 if it is TRUE and send only locally if it is FALSE.
863 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * silc_server_replace_id now broadcasts the received replace ID
866 packet if it is not broadcast packet already. The router must
867 broadcast to inform other routers about changed ID.
869 * Added backpointer to server's router into SilcServer context in
870 silcd/server_internal.h.
872 * Fixed silc_server_packet_broadcast to send correct broadcast
875 * The channel key is now distributed to the local client as soon
876 as it is received from the router (in router environment) so that
877 no other packet may be sent for the channel until client has
880 * silc_server_remove_channel_user now broadcasts the received
881 Remove Channel User packet if it is not broadcast packet already.
882 The router must broadcast to inform other routers about removed
885 * Added users field into SilcPacketContext that is a reference count
886 of the context. One can increase the reference count by calling
887 silc_packet_context_dup which is now changed to just increase the
888 reference count instead of duplicating the data. The reference
889 count is decresed by calling silc_packet_context_free that will
890 free the data after the reference count hits zero.
892 For now on the packet context and everything allocated into it
893 (including the raw packet from network) must be freed by calling
894 the new silc_packet_context_free function. Added also new function
895 silc_packet_context_alloc that must be used now to allocate the
896 context. This also means that if a routine is asynchronous from
897 silc_[client/server]_packet_parse_type the packet context must
898 be duplicated by calling silc_packet_context_dup. Otherwise it
899 gets free'd after silc_[client/server]_packet_parse_type returns.
900 Also, one must remember that if packet is duplicated then its
901 reference count must be decresed by calling the free function as
902 many times as it was duplicated.
904 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
905 from both client and server.
907 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Made joining to a channel working in router environment.
911 * Cleaned up JOIN command on server side and create function
912 silc_server_command_join_channel internal routine to make the
915 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Changed silc_command_pending list to SilcDList. Also, added
918 `ident' field to SilcServerCommandPending structure to identify
919 the reply and to call correct callback.
921 Added silc_server_command_pending_check function to replace the
922 corresnponding macro. The silc_command_pending list is not
925 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
926 to set identifier to previously allocated Command Payload. It
927 is used to set identifier for command when resending Command
930 * Added silc_command_payload_encode_payload to encode Command
931 Payload buffer from SilcCommandPayload structure.
933 * Added silc_argument_payload_encode_payload to encode Argument
934 payload buffer from SilcArgumentPayload structure.
936 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Changed WHOIS command to support router connection on server side.
939 The whois request is always sent to router unless the server is
940 standalone server. After server has received the reply from the
941 router will it send the reply to the client.
943 * Added silc_server_packet_broadcast into silcd/server.[ch] to
944 broadcast received broadcast packet. The function is used only
945 by router. The broadcast packet is always sent to the router's
948 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
949 render given ID to printable string, for log files for example.
951 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Made basic router to router connections working. At least they
954 can now connect to each other but nothing really works the way
955 they are supposed - yet.
957 * Added new initiator token to RouterConnection configuration
958 file in silcd/serverconfig.[ch]. It is used to tell whether we
959 are the initiator to the remote router or whether we'll expect
960 the other end to connect.
962 * Moved registering of listener task to silc_server_init, hence
963 the server starts listenning as soon as it is run, even if it
964 does not have connections to other routers. Let's see how well
967 * Changed default connection retry timeouts for more suitable in
970 * Removed cipher and such arguments from silc_idlist_add_client
971 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
972 Added new function silc_idlist_add_data to add the keys and stuff
975 * Added SilcIDListData structure and added it to SilcClientEntry
976 and SilcServerEntry as their first field in the structure. This
977 way we can explicitly cast the ID entries to the SilcIDListData
978 structure and get common data for the entries. In past, we had
979 to first check what type of connection it is and then cast it to
980 correct ID entry type. Now, we can directly cast the opaque
981 pointer to the SilcIDListData (no matter what ID entry it actually
982 is) and get the data needed.
984 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Wow, found a bug in scheduler. The scheduler uninitialized itself
987 in some circumstances even if threre were timeout tasks, though not
988 IO tasks, but tasks anyway. Now fixed.
990 * Defined SilcServerConnection structure to hold connection specific
991 stuff about directly connected servers and routers. The definition
992 is currently in silcd/server_internal.h. I thought about having
993 a bit more important role fro this struct but for now it is used
994 only when connecting to other server (or router actually).
996 * Added connecting retry support in server when connecting to
997 router(s). The retry feature implement exponential backoff
998 algorithm. Also, added SilcServerParams structure to hold default
999 parameters for server. For now, it include these retry settings
1000 and are hard coded. After server is moded to be as Silc Server
1001 Library this structure will be more important.
1003 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Changed client librarys channel->clients table to SilcList and
1006 changed code accordingly.
1008 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Changed client's channel table to SilcList and changed code
1011 accordingly. Also changed SilcChannelClientEntry to include back-
1012 pointer to the channel so that client entry can use that structure
1013 as list as well and we have fast cross-reference to the channel.
1014 This change dramatically decreased the complexity of channel
1015 handling with client entry and vice versa (removed one extra
1016 loop when searching for channel entry from many functions).
1018 * Changed server->sim from table to SilcDList and changed code
1021 * NAMES command can now be used from user interface. It will show
1022 the user list on the channel, neatly.
1024 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1025 Code now saves realname of the user if it becomes available.
1027 * Renamed configure.in to configure.in.pre and made ./prepare
1028 script to automatically add correct version string to
1029 configure.in which it creates from configure.in.pre.
1031 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * NAMES command reply now shows users mode with the nickname when
1036 * Moved silc_client_ch[u]mode[_char] functions from
1037 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1038 place sucks, they are utility functions and should be in some
1041 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1043 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1046 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Added TRQ (efficient deque and list library) into lib/trq. This is
1051 a very good list library that is currently used in the SILC. Defined
1052 SilcList API over the library because I didn't like the API very
1053 much. See lib/trq/silclist.h for the API and examples of how to
1054 use the API. Fixed various places in the code to use the new
1055 SilcList API. The SilcList is meant for lists that has a structure
1056 already defined as a list. It is not suitable to add just some
1057 context to the list (in TRQ, the context is the list actually).
1059 So, I defined SilcDList that can be used for the purpose where
1060 predefined list structure does not exit. This can be used as
1061 such list. Now some context just can be added to the SilcDList.
1062 Currently this list is not used in the SILC just yet, though there
1063 are a lot places where this can replace dynamically allocated
1064 tables and I will fix these places, later, to use SilcDList.
1065 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1066 and use TRQ internally).
1068 Also fixed some annoying warning messages that the original TRQ
1069 code generated. Also minor changes to TRQ's Makefile.in.
1071 * Added support for querying by Client ID to both WHOIS and
1072 IDENTIFY commands into server, as required by the protocol.
1074 * Removed method function pointers from SilcBuffer structure. They
1075 weren't used to anything and just increased the context size for
1076 no good reason. This change also made silc_buffer_alloc and
1077 silc_buffer_free functions inline functions.
1079 * Disabled command flooding detection support until it's fixed so
1080 that it accepts commands in but does not execute them more than once
1083 * Added silc_net_localhost(), to return local hostname, into
1084 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1085 that must be initialized before calling silc_client_init.
1087 * Added new function: silc_server_send_notify_on_channels to send
1088 notify messages to all channels client has joined. It is assured
1089 that the message is sent only once per client.
1091 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1092 lib/silcutil/silcutil.[ch] as silc_format function. The new
1093 function is generic and is used by server as well, not only by
1094 the logging routines.
1096 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1097 the provided version string was not acceptable. Added new function:
1098 silc_ske_check_version into lib/silcske/silcske.h. The function
1099 must be implemented by the application (client or server) and it
1100 does not reside in the SKE library. The function checks the version
1101 string remote end sent.
1103 * Added back pointers (to opaque context and to SilcSocketConnection)
1104 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1106 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1107 duplicate packet context structure.
1109 * Changed `notify' client operation to send same arguments as client
1110 receives from server except for ID's. ID's are mapped to correct
1111 ID entry and that is returned. Also, if channel entry is not sent
1112 by server but the notify is for channel the channel entry is sent
1113 to application (otherwise application doesn't know that it is for
1114 channel (library gets it from packet's Destination ID)).
1116 * Added silc_client_remove_from_channels into client library to
1117 remove a client from all channels it has joined to. Used when
1118 received SIGNOFF notify from server. Added also new function
1119 silc_client_replace_from_channels to replace old ID entry with
1120 new ID entry on all channels. Used when received NICK_CHANGE
1123 * Fixed ID Cache list handling in silc_idlist_get_client in
1124 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1125 to get (or query) client by ID.
1127 * Updated TODO list.
1129 * Added connection authentication status message defined by the
1130 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1131 support for these into the code in client and server side.
1133 * Added generic function silc_client_send_command to send any command
1134 with variable argument list. Application should use this function
1135 to send commands if the command functions provided by the library
1136 does not suite for the application's user interface needs.
1138 * Added new `failure' client operation. Application is notified about
1139 received failure packet if client is executing a protocol. In this
1140 case the protocol's execution has failed.
1142 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1143 is required by the protocol.
1145 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1146 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1149 * Added status flag to SilcSKE object to indicate realtime status
1150 of the SKE protocol.
1152 * Application receives now exactly same command reply arguments as
1153 the library receives from server. However, if ID is received the
1154 corresponding ID entry is returned to the application (eg. Client
1155 ID is mapped to correct SilcClientEntry entry and that is returned).
1156 Changed command_reply client operation due to this change.
1158 * Changed all ID's in commands and in command replys as ID Payloads.
1159 Change affected both client and server side codes.
1161 All ID's sent in SILC network (with execption of ID's in SILC
1162 Packet header) are sent in ID Payload to support variable length
1165 * Server now notifies nick changes and notifies all clients on
1166 the channels about the new nickname (about the new Client ID,
1169 * Implemented CMODE command to change channel modes. Supports all
1170 channel modes defined by the protocol specs except ban and invite
1171 lists. (Also, private channel key mode is supported but support for
1172 setting private channel key in client is missing, thus, this mode
1173 has no effect on client side (except that server requires that the
1174 client uses private channel key and normal channel traffic does not
1177 Also, invite mode works per se, but INVITE command does not work
1178 yet correctly, so you can set channel as invite only channel but
1179 inviting clients to the channel does not work (it is yet to be
1180 thought what's the best way to do it).
1182 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1183 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1184 Implemented CUMODE command to change user's mode on the channel.
1185 Supports all modes defined by the protocol specs.
1187 * Added NAMES command reply to return users modes on the channel.
1189 * Removed unnecessary and slow ciphers from lib/silccrypt.
1191 * Set SO_KEEPALIVE option to connection sockets by default.
1193 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1195 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1196 redefined the Notify Payload into protocol specs.
1198 * Added silc_id_payload_parse_id to get ID directly from raw
1201 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1204 accept searching by Client ID as well.
1206 * Added support for LEAVE and SIGNOFF notify types in client library.
1208 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1209 to parse ID Payload from raw data.
1211 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added flags parameter into silc_ske_assemble_security_properties
1214 function in lib/silcske/silcske.[ch].
1216 * Changed notify client operation to fit better for notify messages
1217 sent by server. The notify payload received from server is now
1218 passed to the application (after parsing it to SilcNotifyPayload).
1219 It is application's responsibility to retrieve the arguments
1220 from the payload and show the message the way it wants. The message
1221 sent by server is implementation specific.
1223 * Changed public keys to comply with the protocol specification.
1224 Old public keys are not supported anymore and are not compatible.
1226 * Removed nickname from Channel Payload as the latest draft removed
1227 it. The client must resolve the nickname from the NAMES command
1228 reply received when it joined the channel.
1230 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1232 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Fixed some errors in protocol specification drafts.
1236 * Created lib/silccore/silcnotify.c to implement Notify Payload
1237 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1238 generic payloads described by protocol specifications. The file
1239 includes implementations for ID Payload and Argument Payload.
1241 * Changed Command Payload implementation to use the new Argument
1242 Payload. Changed command_xxxx_payload to command_payload_xxxx
1243 to comply with SILC coding conventions.
1245 * Added suppport for Argument Payload handling in Notify Payload
1246 implementation as protocol requires it. Added the new support
1247 into server and client lib as well.
1249 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1251 * Added support for multiple nicknames on same channel. [n] is
1252 added locally to the nickname if there are more than one same
1253 nicknames on the channel.
1255 * Server now sends all nicknames that matched WHOIS request.
1256 Client also shows the list received from server.
1258 * Added TOPIC command to client side. User can now set and show
1259 current topic on channel.
1261 * Added MOTD command to client and server. Also, server sends the
1262 motd when client connects to the server.
1264 * Changed version strings to comply ISO 8601.
1266 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Fixed protocol error handling in client library. It should now
1269 cope even if the SKE fails for some reason.
1271 * Made new protocol specification drafts for submitting to IETF.
1273 * Implemented TOPIC command to server in silcd/command.c.
1275 * Added two new notify types into lib/silccore/silcnotify.h:
1276 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1277 notify nickname change and topic setting/change on a channel.
1279 * API change of command_reply operation in client library. The
1280 application gets now the status type received from server as well.
1282 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1286 * Cras fixed and optimized the packet handling even further and
1287 it should work now. Minor change to the prototype of function
1288 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1290 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Added new function into lib/silcutil/silcschedule.[ch]:
1293 silc_schedule_with_fd to select() a specified fd. The function
1294 returns after timeout expires or data arrives or goes. The
1295 function is used by packet routines to wait that all data is
1296 received from network.
1298 * Fixed data reading from network in lib/silccore/silcpacket.c.
1299 The code now assures that all data is read from the fd and then
1300 continues packet processing. This was a bug fix since the code
1301 used to drop some data in some circumstances.
1303 * Added new function into lib/silcclient/client.[ch]:
1304 silc_client_start_key_exchange to start key exchange after
1305 connection has been established to server. The code internally
1306 now uses this funtion but its main purpose was to provide it
1307 for applications that perform their own connecting. After
1308 application has created a connection it merely calls this
1309 function to start the key exchange between client and server.
1310 The library takes care of everything else after that.
1312 Updated also lib/silcclient/README to explain the usage of
1315 * Do not send to application information that connection has
1316 been established. Application gets notified it by connect
1319 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Applied cras's patch to add silc_schedule_one function. The
1322 function runs scheduler once and returns.
1324 * Fixed the scheduler after cras messed it up. The timeout
1325 handling works now as it's supposed to work.
1327 * Added into lib/silccore/ silcnotify.h to include notify
1328 message types support. Changed silc_server_send_notify*
1329 functions, in server.[ch], to support those new notify types.
1330 Added the support for the notify types into client library,
1331 as well. Added new notify client operation into ops.h in
1334 * Changed silc_server_packet_send_to_channel to send normal
1335 packets instead of just channel message packets. The function
1336 is now used to send the notify packets to channels. It is not
1337 used to send channel message packets anymore, as server never
1340 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1341 va_arg()s as it seems to require it nowadays. I guess, if SILC
1342 is compiled with older va_arg() the new code should work anyway.
1344 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Splitted core library. Core library (lib/silccore) includes
1347 now only SILC protocol specific core (and common) components.
1348 Created new utility library (lib/silcutil) that includes more
1349 generic purpose stuff. The stuff for util library was taken
1350 from the old core library. This was minor and easy split.
1352 * Created SILC Client Library (lib/silcclient) that includes
1353 implementation of the SILC client without user interface. This
1354 was major move from silc/ directory. The code has been changed
1355 so that it is transparent towards the user interface. The
1356 silc/ directory includes now the same user interface as before
1357 and it uses the new client library. Read lib/silcclient/README.
1358 Basicly, the client library performs everything else related
1359 to SILC except user interface handling. Also, configuration
1360 files are considered to be part of user interface and library
1361 does not handle them.
1363 This change also changed a lot of structures, function naming etc.
1364 Most important change was that SilcClientWindow object was
1365 renamed to SilcClientConnection in the client library. Created
1366 also new file lib/silcclient/ops.h. Also added new files
1367 silc/local_command.[ch] and silc/client_ops.[ch].
1369 All these changes were made to make it easier for user interface
1370 designers to create what ever user interface for the SILC client
1373 It is also expected that the server will be moved to lib
1374 directory as well and SILC Server Library will be created;
1375 sometimes in the future.
1377 * Removed Local commands from lib/silccore/silccommand.h as
1378 they are application specific and new client library does not
1379 handle any of those anymore.
1381 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1382 old client implementation in silc/.
1384 * Added support for callback functions in SILC_LOG_* macros.
1385 Application can now set its own callbacks that will be called
1386 instead of using the default functions that will always print
1387 the debug messages to stderr (or stdout). Also, debugging can
1388 now be disabled by setting silc_debug to FALSE and re-enabled by
1389 setting it to TRUE. Note, that logging will still work even
1390 if debugging is disabled.
1392 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1393 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1394 silc_log_reset_debug_callbacks.
1396 * To enable debugging in silc client one must give now -d
1397 option on command line.
1399 * Changed silc_schedule_init to automatically allocate task queues
1400 if they are not allocated before calling it.
1402 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1404 * Added GMP 3.1 into math library.
1406 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1408 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1409 a channel in SILC network. The packet is used by servers and
1410 routers to notify other routers that user has left a channel.
1411 This little feature was missing until now. Added the feature
1412 to protocol specification as well.
1414 Added functions: silc_server_send_remove_channel_user and
1415 silc_server_remove_channel_user into server.[ch].
1417 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1418 lib/silccore/silcpacket.h. However, they are not implemented
1421 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Fixed joining to a channel and sending channel messages
1424 between server and router. The channel message sending should
1425 now work inside a cell.
1427 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Fixed the private message sending between server and router.
1430 The private message sending should now work inside a cell.
1432 * Added silc_server_replace_id into server.[ch] to replace
1433 existing ID in the SILC network.
1435 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1436 and silc_idlist_replace_server_id into idlist.[ch] in server.
1438 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Fixed the server to server connections. Server can again now
1441 connect to router. Router to router connections probably does
1444 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Added dynamic protocol registering support. Now protocols can
1447 registered and unregistered on the fly. Patch by cras.
1449 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * Added lib/contrib directory to hold routines that some platforms
1452 don't have but are needed by SILC.
1454 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1455 into lin/contrib to provide getopt() and getopt_long() for
1456 those who don't have it.
1458 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added AWAY command to client. When away message is set and
1461 client receives a private message packet the client automatically
1462 replies to the sender with the away message.
1464 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1465 bug seemed to be the cause of recent problems when compiling
1468 * Added version detection support to SKE protocol specification
1469 and added the new changes to the SKE implementation as well.
1470 There were other minor changes in the SKE protocol as well.
1472 Many changes in lib/silcske/silcske.[ch] and in
1473 lib/silcske/payload.[ch].
1475 * Added ^U functionality, clear input line. Patch from cras.
1477 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1479 * Mainly small bugfixes on core library. Fixed some debugging
1480 logging and buffer overflow in silclog.c.
1482 * Updated config.sub and config.guess on the distribution tree.
1484 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Added command lagging support in server. Client may execute
1487 commands now only once in two seconds.
1489 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Optimized packet reception. MAC computation and checking is now
1492 also more optimized. A lot previously duplicated code is now
1493 used as generic by both client and server.
1495 * Fixed key pair generation in clientutil.c
1497 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Added into lib/silccore/silcbufutil.[ch] new function;
1500 silc_buffer_realloc.
1502 * Moved generic packet sending/encryption functions to
1503 lib/silccore/silcpacket.[ch] from client and server. Some
1504 rewriting of the functions.
1506 * Moved all generic packet reception/decryption functions to
1507 lib/silccore/silcpacket.[ch] from client and server. The
1508 packet processing is now much cleaner in both client and server.
1509 These were major changes in both client and server.
1511 * Created many common functions in server to do packet sending.
1512 Previously code were duplicated a lot, this has been removed
1515 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Rewrote major parts of the ID cache system. Don't know
1518 whether it is better now or not but at least the API is more
1521 * Major rewrite on ID cache stuff on client because of the ID
1522 cache API changes. Added idlist.c to client.
1524 * Also major rewrite on ID cache stuff on server as well.
1525 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1526 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1527 in hand, instead they are all put into the ID cache system now.
1528 All server_idlist_* routines uses ID cache now instead of
1529 traversing its own lists (those lists does not exist anymore).
1530 SilcIDList though still exists. Also, SilcXXXEntry's are
1533 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Finally made the SKE implementation compliant to the protocol
1536 specification. All mp integers are now binary encoded as
1537 opposed being HEX encoded.
1539 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1542 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1543 functions: silc_[encode/decode]_pem. Also added function
1544 silc_encode_pem_file to PEM encode with newlines ('\n') for
1547 * SILC public keys are now encoded either PEM or binary. Same
1548 option is for private keys as well. By default private keys
1549 are binary encoded and public keys PEM encoded. Silly HEX
1550 encoding were removed.
1552 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1553 function to create fingerprints.
1555 * Fixed a bug in SHA1; does not change the original data anymore.
1557 * Partly implemented INFO command on client and server side.
1558 Fixed CLEAR command. Changes to SERVER command; show current
1559 server(s) when giving command without arguments. Added
1560 VERSION command to client.
1562 * Added check to server that unregistered connections cannot
1563 execute commands (unless it is specificly allowed).
1565 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Fixed screen refresh.
1569 * Fixed channel joining bug from client. On some circumstances
1570 client tried to join to a channel it had already joined.
1572 * Added public key verification process into client's protocol.c.
1573 The client now verifies the public key from user and saves
1574 it into ~./silc/serverkeys/ directory.
1576 Added into: clientutil.[ch]: silc_client_verify_server_key.
1578 * Changed SKE protocol's silc_ske_initiator_finish function
1579 to accept callback function that verifies the received public
1580 key. Removed old silc_ske_verify_public_key function.
1582 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1585 silc_pkcs_private_key[_data]_set.
1587 * Made the password and public authentication more cleaner in
1588 server's protocol.c.
1590 * Removed historic and obsolete protocol `channel_auth' from
1591 both client and server.
1593 * Removed wrong way of sending command status messages from
1594 server to client in server's command.c. The old way violated
1595 protocol specification.
1597 Changes to silccore/silccommand.[ch]: removed
1598 silc_command_encode_status_payload -> not needed anymore,
1599 changed silc_command_encode_payload_va to accept extra
1600 argument on variable argument list. The argument type must
1601 now be provided to the function. Also, added new function:
1602 silc_command_encode_reply_payload_va which is same as
1603 normal command_encode_payload_va except command status type
1604 is provided as extra argument.
1606 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Added ~./silc directory handling. The directory includes the
1609 public and private keys for the client.
1611 Added silc_client_check_silc_dir, silc_client_create_identifier
1612 and silc_client_load_keys.
1614 * Implemented SILC protocol compliant public key. Added public
1615 and private key saving to and loading from files.
1617 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1618 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1619 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1620 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1621 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1623 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1624 silc_pkcs_load_[public/private]_key.
1626 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added silc_server_get_route (route.[ch]) to get connection
1629 data for the fastest route for given ID.
1631 * Implemented INVITE command on client and server. The command
1632 were re-defined in the SILC Protocol Specification and the
1633 implementation now complies with the specification.
1635 * Implemented PING command on client and server.
1637 * Implemented NAMES command on client and server. The server side
1638 supports currently only normal server not router server yet.
1639 Some changes to NAMES definition in SILC protocol specification.
1641 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Implemented LEAVE command on client and server.
1645 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1646 again. This change was made to the protocol as well. Server
1647 should not violate the protocol specification anymore.
1649 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1652 was tested. SOCKS4 was not but should work anyway.
