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 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * The client entry's userinfo pointer must be always valid.
20 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
21 will fail since it requires the userinfo. Now, the userinfo
22 is allocated as "" if actual userinfo does not exist. Actually,
23 it must exist and it is totally Ok to drop client connections
24 that does not announce the userinfo. However, we will make
25 this workaround for now.
27 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
28 to return the remote port by socket.
30 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
33 SILC_SERVER_PENDING_EXEC and added an new macro
34 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
35 data or when error occurs while processing the pending command.
37 Added new argument `destructor' into silc_server_command_pending
38 and to the SilcServerCommandPending object. This destructor is
39 now called after calling the pending callback or if error occurs
40 immediately. If error occurs the actual pending callback won't
41 be called at all - only the destructor. The destructor may be
42 NULL if destructor is not needed.
44 All this applies for client library code as well. Similar
45 changes were made there as well for the pending commands.
47 In the client, the application must now allocate the
48 SilcClientCommandContext with the silc_client_command_alloc
51 * Added reference counter to the SilcServerCommandContext. Added
52 function silc_server_command_alloc and silc_server_command_dup
55 Same type of functions added to the client library for the same
58 * Removed the cmd_ident from IDListData away since it is now
59 global for all connections. It is the command identifier used
60 in command sending and with pending commands. The affected file
63 * Added reference counter to the SilcSocketConnection objecet to
64 indicate the usage count of the object. The object won't be
65 freed untill the reference counter hits zero. Currently only
66 server uses this, and client ignores it. The client must be
67 set to use this too later. The affected files are
68 lib/silccore/silcsockconn.[ch]. Added also the function
69 silc_socket_dup to increase the reference counter.
71 This was mainly added because it is possible that the socket
72 is removed underneath of pending command or other async
73 operation. Now it won't be free'd and proper DISCONNECTING
74 flags, etc. can be set to avoid sending data to connection that
77 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
78 the connection. After that it sets SILC_SET_DISCONNECTED.
79 It is, however, possible that the socket data is not still freed.
80 The silc_server_packet_process now checks that data is not
81 read or written to connection that is DISCONNECTED. The socket
82 get's freed when the reference counter hits zero.
84 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Changed the client operation API: channel_message operation's
87 `sender' is now the client entry of the sender, not the nickname
88 and the `channel' is the channel entry, not the channel name.
90 In the private_message operation the `sender' is now also the
91 client entry of the sender not the nickname.
93 Affected file is lib/silcclient/ops.h and all applications
94 using the client operations.
96 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Moved the calling of ops->connect() from connect_to_server_final
99 into receive_new_id functin since that is the point when the
100 client is actually allowed to send traffic to network. The
101 affected file is lib/silcclient/client.c.
103 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
105 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
106 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
107 (if needs broadcasting) instead of broadcasting the packets one
108 by one which would make a burst in the network traffic.
110 * Added `broadcast' argument to the functions in silcd/server.[ch]
111 silc_server_create_new_channel[_with_id] to indicate whether
112 to send New Channel packet to primary router.
114 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Added new function into the silcd/server.[ch] files:
117 silc_server_create_new_channel_with_id to create new channel with
118 already existing Channel ID.
120 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
121 lib/silccore/silcpacket.h. This packet is used t send list of
122 Set Mode payloads inside one packet. Server uses this to set
123 the modes for the channels and clients on those channels, that it
124 announced to the router when it connected to it. The protocol
125 specification has been updated accordingly.
127 * The silc_server_new_channel did not handle the packet coming
128 from normal server as it normally does not send that. However,
129 when it announces its channels it does send it. Implemented
130 the support for that.
132 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
133 into the file lib/silccore/id.h.
135 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
137 * Fixed memory leaks in the functions silc_idlist_del_client,
138 silc_idlist_del_channel and silc_idlist_del_server in the file
139 silcd/idlist.c. All of those leaked like a sieve.
141 * Fixed some small memory leaks in the client's function
142 silc_client_notify_by_server.
144 * Added functions into silcd/server.c: silc_server_announce_clients,
145 silc_server_announce_channels and silc_server_announce_server.
146 These functions are used by normal and router server to announce
147 to its primary router about clients, channels and servers (when
148 router) that we own. This is done after we've connected to the
151 These functions effectively implements the following packet types:
152 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
153 and SILC_PACKET_NEW_ID_LIST.
155 * Added new functions into the silcd/packet_receive.[ch]:
156 silc_server_new_id_list, silc_server_new_channel_list and
157 silc_server_new_channel_user_list to handle the incoming
158 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
160 * Added support of changing Channel ID in the function
161 silc_server_replace_id. If the server that announces a channel
162 to the router already exists in the router (with same name but
163 with different Channel ID), router is responsible to send
164 Replace ID packet to the server and force the server to change
165 the Channel ID to the one router has.
167 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
168 client that the Channel ID has been changed by the router. The
169 normal server sends this to the client. Client must start using
170 the new Channel ID as the channel's ID.
172 Implemented handling of this new type into lib/silcclient/client.c
173 into the function silc_client_notify_by_server.
175 * Added new function silc_idlist_replace_channel_id into the files
176 silcd/idlist.[ch] to replace the Channel ID.
178 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Call silc_server_command_identify_check always when processing
181 the IDENTIFY command in silcd/command.c
183 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
185 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
186 send keepalive packets. The packet can be sent by clients,
189 Added function silc_socket_set_heartbeat into the file
190 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
191 If not set, the heartbeat is not performed. The actual
192 heartbeat is implemented in the low level socket connection
193 library. However, application is responsible of actually
196 Added silc_server_send_heartbeat to send the actual heartbeat
197 packet into silcd/packet_send.[ch]. Server now performs
198 keepalive with all connections.
200 * Added silc_task_get_first function into lib/silcutil/silctask.c
201 to return the timeout task with shortest timeout. There was a bug
202 in task unregistration that caused problems. TODO has been
203 updated to include that task system must be rewritten.
205 * The client library will now resolve the client information when
206 receiving JOIN notify from server for client that we know but
207 have incomplete information.
209 * Rewrote parts of silc_server_remove_from_channels and
210 silc_server_remove_from_one_channel as they did not remove the
211 channel in some circumstances even though they should've.
213 * Encryption problem encountered in server:
215 The LEAVE command used to send the Channel Key packet to the
216 router immediately after generating it. However, the code
217 had earlier sent Remove Channel user packet but not immediately,
218 ie. it was put to queue. The order of packets in the router
219 was that Channel Key packet was first and Remove Channel User
220 packet was second, even though they were encrypted in the
221 reverse order. For this reason, MAC check failed. Now, this
222 is fixed by not sending the Channel Key packet immediately but
223 putting it to queue. However, this is more fundamental problem:
224 packets that are in queue should actually not be encrypted
225 because packets that are sent immediately gets encrypted
226 actually with wrong IV (and thus MAC check fails). So, packets
227 that are in queue should be encrypted when they are sent to
228 the wire and not when they put to the queue.
230 However, the problem is that the current system has not been
231 designed to work that way. Instead, the packet is encrypted
232 as soon as possible and left to the queue. The queue is then
233 just purged into wire. There won't be any fixes for this
234 any time soon. So, the current semantic for packet sending
237 o If you send packet to remote host and do not force the send
238 (the packet will be in queue) then all subsequent packets to the
239 same remote host must also be put to the queue. Only after the
240 queue has been purged is it safe again to force the packet
243 o If you send all packets immediately then it safe to send
244 any of subsequent packets through the queue, however, after
245 the first packet is put to queue then any subsequent packets
246 must also be put to the queue.
248 Follow these rules and everything works fine.
250 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Added new function silc_server_remove_clients_by_server to
253 remove all client entries from ID list when the server connection
254 is lost. In this case it is also important to invalidate all
255 client entires as they hold the invalid server entry. This
256 fixes fatal bug when server has lost connection and will reconnect
259 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
261 * Made some sanity checks to silc_server_daemonise like to check
262 whether the requested user and group actually exists.
264 * Added sanity check to SKE's silc_ske_responder_finish to check
265 that the public and private key actually is valid.
267 * Invalidate the client's nickname when receiving Replace ID
268 packet and the Client ID is being replaced. This means that the
269 server will query the nickname if someone needs it (client)
272 * Sort the ID Cache in client library when the ID Cache data
273 has changed (needs sorting).
275 * Do not allow for SILC client to create several connections to
276 several servers. The client does not support windows right now
277 and generating multiple connections causes weird behaviour.
279 Irssi-silc client does support windows and can handle several
280 connections without problems, see: www.irssi.org and SILC plugin.
282 * Fixed some places where client was added to the IDList. The
283 rule of thumb is following (in order to get everything right):
284 If the client is directly connected local client then the
285 `connection' argument must be set and `router' argument must be
286 NULL to silc_idlist_add_client function. If the client is not
287 directly connected client then the `router' argument must
288 bet set and the `connection' argument must be NULL to the
289 silc_idlist_add_client function.
291 * The funtion silc_server_packet_send_local_channel actually did
292 not check whether the client was locally connected or not. It
293 does that now. Fixed a bug related to LEAVE command.
295 * Fixed Remove Channel User payload parsing bug in server's
296 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
298 * The server's silc_server_save_channel_key now checks also the
299 global ID list for the channel as it might not be in the local
300 list. Fixed a bug related to LEAVE command.
302 * Is this the end of the [<unknown>] buglet that has been lurking
303 around for a long time? A little for loop fix in server's
304 silc_server_command_whois_parse that is used by both IDENTIFY
305 and WHOIS command. At least, this was a clear bug and a cause
306 of one type of [<unknown>] buglet.
308 * WHOIS and IDENTIFY commands call the function
309 silc_server_command_[whois/identify]_check function even if
310 we are not router server.
312 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Added --with-gmp configuration option. If set the GMP
315 is always compiled in the SILC source tree. If not set then
316 it is checked whether the system has the GMP3 installed. If
317 it has then the GMP won't be compiled (the system's headers
318 and library is used), if it doesn't have it then the GMP is
319 compiled in the SILC source tree.
321 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Changed RSA private exponent generation to what PKCS #1
324 suggests. We try to find the smallest possible d by doing
325 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
326 not security fix but optimization.
328 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Added new config entry [Identity] to fork the server and run
331 it as specific user and group. A patch from Bostik.
333 * Imported Dotconf configuration library into lib/dotconf.
334 This will be used to create the SILC configuration files later.
335 It will appear in the distsribution after this commit.
337 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
339 * A big code auditing weekend happening. Auditing code for
340 obvious mistakes, bugs and errors. Also, removing any code
343 Removed files for being obsolete:
345 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
346 inline in the file lib/silcutil/silcbuffer.h)
348 o lib/silcutil/silcbufutil.c (the header has inline versions)
350 Changed code to fix possible error conditions:
352 o The buffer formatting routines now check that the destination
353 buffer really has enough space to add the data. This applies for
354 both buffer formatting and unformatting
355 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
356 unformatting was changed to accomodate following rules:
357 XXX_*STRING_ALLOC will allocate space for the data into the pointer
358 sent to the function while XXX_*STRING will not allocate or copy
359 the data into the buffer. Instead it sets the pointer from the
360 buffer into the pointer sent as argument (XXX_*STRING used to
361 require that the pointer must be allocated already). This change
362 makes this whole thing a bit more consistent and more optimized
363 (note that the data returned in the unformatting with XXX_*STRING
364 must not be freed now). The routines return now -1 on error.
366 o Tried to find all code that use buffer_format and buffer_unformat
367 and added return value checking to prevent formatting and
368 especially unformatting errors and possible subsequent fatal
371 o Changed ske->x and ske->KEY to mallocated pointers in
372 lib/silcske/silcske.h. Fixed possible data and memory leak.
374 o Added return value checking to all *_parse* functions. Fixed
375 many memory leaks as well.
377 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
378 so that buffer overflows would not happen. All code now also
379 checks the return value as it can fail.
381 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added reconnection support to server if the normal server looses
384 its connection to the router (for example if router is rebooted).
385 The server performs normal reconnection strategy implemented
386 to the server. Affected file silcd/server.c.
388 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Added new packet type SILC_PACKET_SET_MODE that is used to
391 distribute the information about changed modes (for clients,
392 channels and clients channel modes) to all routers in the
393 network. Updated the protocol specification accordingly.
395 Added functions into silcd/packet_send.c and
396 silcd/packet_receive.c: silc_server_send_set_mode,
397 silc_server_set_mode.
399 Added new files silcmode.[ch] into lib/silccore that implements
400 the encoding and decoding of Set Mode Payload. Added new type
401 SilcSetModePayload. Moved the definitions of different modes
402 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
404 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Oops, a little mistake in server's connection authentication
407 protocol. The protocol is not ended with FAILURE but with
408 SUCCESS if the authentication is Ok. :) Affected file is
411 * Implemented NICK_CHANGE notify handling in server in the file
412 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
413 the local clients on the channel. After the changing nickname
414 in router environment snhould work and the [<unknown>] nickname
415 should appear no more.
417 The silc_server_replace_id function that receives the Replace ID
418 payload now sends the NICK_CHANGE notify type also in the file
419 silcd/packet_receive.c
421 * Changed WHOIS and IDENTIFY command to support the maximum amount
422 of arguments defined in protocol specs (3328 arguments). This
423 fixed a bug that caused problems when there were more than three
426 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Added extra parameter, command identifier, to the
429 silc_client_send_command so that explicit command identifier
432 Changed that ID list routines uses specific command identifier
433 when sending WHOIS/IDENTIFY requests to the server so that they
434 can be identified when the reply comes back.
436 Affected files lib/silcclient/command.[ch],
437 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
439 * Added `sender' argument to silc_server_packet_send_to_channel
440 to indicaet the sender who originally sent the packet to us
441 that we are now re-sending. Ignored if NULL. Affected file
442 silcd/packet_send.[ch].
444 * Added some server statistics support in silcd/server_internal.h
445 SilcServerStatistics structure and around the server code. Also
446 send some nice statistics information when client is connecting
449 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * Fixed channel ID decoding in server's JOIN command reply in
452 silcd/command_reply.c
454 * Fixed braodcasting of replace ID payload to not to send it if
455 we are standalone server in silcd/packet_receive.c.
457 * Fixed all channel message sending routines to not to send
458 packets to clients that has router set, since they are routed
459 separately in the same function earlier. Affects file
460 silcd/packet_send.c and all channel packet sending functions.
462 * In USERS reply, res_argv[i] are not allocated, the table
463 is allocated. Thus changed that free the table, not its
466 * In server's whois_check and identify_check if the client is
467 locally connected do not send any WHOIS commands - they are not
470 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Fixed some minor bugs in client when sending WHOIS command. The
473 arguments was in wrong order.
475 * Removed statis function add_to_channel from server in
476 silcd/command.c that was previously used with the joining but
479 * Tested USERS command in router environment successfully with two
480 routers, two servers and two clients.
482 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Reorganized the USERS command and command reply in client library
485 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
486 When the command is given by user we register a pending command
487 callback that will reprocess the command after the reply has been
488 received from the server. When reprocessing the packet we then
489 display the information. Thus, the USERS information is displayed
490 now in the command callback instead of in the command reply
491 callback. The processing of the command is same as previously
492 when server has sent the command reply in the JOINing process.
494 * Added to USERS command in silcd/command_reply.c to join the client,
495 we didn't use to know about, to the channel after we've created
496 a client entry for it. Also, for clienet we did know already still
497 check whether it is on the channel or not and add it if not.
499 * Removed silc_server_command_join_notify as the function and its
502 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Changed the client's pending command handling to the same as the
505 server's pending command handling. It is also now possible to
506 execute command reply functions from other command reply
507 function as the function callbacks for commands and command
508 replies are one and same. The pending commands are not static
509 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
510 in client connection context. Thus, pending commands are server
511 connection specific as it is convenient.
513 Changed the function silc_client_command_pending and
514 silc_client_command_pending_del and added new function
515 silc_client_command_pending_check. Removed the
516 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
519 * Added cmd_ident, current command identifier, to the client
520 connection context in lib/silcclient/client.h to keep track on
521 command identifiers used in command sending. Client's command reply
522 function handling now supports the mandatory command identifiers.
524 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
525 funtions in client to fully support pending command callbacks.
527 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
528 as one of the arguments to the application in the command reply
531 * NOTE: The FORWARDED flag is depracated. It used to be depracated
532 before first releasing SILC but came back. Now it is removed again
533 and should come back nomore. The FORWARDED flag was used only
534 by the JOINing procedure by forwarding the command packet to router.
535 Now, the JOINing procedure has been changed to more generic (due
536 to various router environment issues) and FORWARDED is not needed
537 anymore for anything. The protocol specification is yet to be
540 Now, removed silc_server_packet_forward from server and the flag
541 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
543 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * Renamed NAMES command to USERS command. The NAMES was named that
546 due to historical reasons. Now it is renamed. Also, rewrote
547 parts of the USERS command. The nickname list is not sent anymore
548 by the server. Only Client ID and mode lists are sent in the USERS
549 command. Changed this also to the protocol specification.
551 The client now resolves the names and stuff after it receives
552 the USERS list from the server when joining to the channel.
554 * WHOIS and IDENTIFY commands has been changed to support multiple
555 Client ID's per command. One can now search for multiple users
556 in the network by sending only one WHOIS or IDENTIFY command.
557 Changed the code and the protocol specifications.
559 * Removed silc_server_command_identify_parse and changed that IDENTIFY
560 uses silc_server_command_whois_parse to parse the request. */
562 * If normal server, do not parse the WHOIS and IDENTIFY requests
563 before sending it to the router. Saves some time.
565 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * Fixed JOIN command on client library. Wrong number of arguments
568 used to crash the client.
570 * Added silc_server_channel_has_global function to check whether
571 channel has global users or not.
573 * Added silc_server_channel_has_local function to check whether channel
574 has locally connected clients on the channel.
576 * The silc_server_remove_from_one_channel now checks whether the
577 channel has global users or not after given client was removed from
578 the channel. It also checks whether the channel has local clients
579 on the channel anymore. If it does not have then the channel entry
580 is removed as it is not needed anymore.
582 * The silc_server_notify now checks on JOIN notify whether the joining
583 client is one of locally connected or global. If it is global then
584 the channel has now global users on the channel and that is marked
585 to the channel entry. Also, it now saves the global client to
586 global list who is joining and JOINs it to the channel. This is
587 for normal server, that is.
589 Changed silc_server_send_notify_on_channel,
590 silc_server_packet_relay_to_channel and
591 silc_server_packet_send_to_channel check if we are normal server
592 and client has router set (ie. global client) do not send the
593 message to that client, as it is already routed to our router.
595 * Implemented LEAVE notify type handling in silc_server_notify
598 * Tested LEAVE command in router environment successfully. Tested
599 with two routers, two servers and two clients.
603 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
605 * Implemented SIGNOFF notify type handling in silc_server_notify
608 * silc_server_remove_id now removes the client entry from all channels
609 it has joined and thusly sends SIGNOFF notify type.
611 * Rewrote the NAMES list generation in server by removing two excess
612 loops. The lists are created now inside one loop.
614 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * silc_server_remove_channel_user checks now also global list
617 for channel and client.
619 * silc_server_new_channel_user checks now both local and global
620 list for channel and client. Fixed a bug in client id decoding.
621 Used to decode wrong buffer.
623 * silc_server_channel_message checks now both local and global
624 list for channel entry.
626 * Tested channel joining (hence JOIN) in router environment
627 successfully. Tested with two routers, two servers and two
630 * Tested channel message sending in router environment successfully.
632 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Added silc_server_save_channel_key into server.[ch] to save the
635 received channel key in Channel Key payload processing. It is
636 also used in JOIN command reply handling.
638 Equivalent function silc_client_save_channel_key added into
639 client.[ch] into client library.
641 * Changed JOIN command reply to send information whether the channel
642 was created or not (is existing already) and the channel key
643 payload. Changed protocol specs accordingly.
645 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
646 the request was sent by ID and not by nickname. Crashed on
649 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
652 now correctly save the received data.
654 * silc_server_free_sock_user_data now notifies routers in the
655 network about entities leaving the network.
657 At the same time implemented functions silc_server_remove_id
658 and silc_server_send_remove_id to receive and send REMOVE_ID
659 packets. The packet is used to notify routers in the network
660 about leaving entities. The ID removed will become invalid in
663 * Added function silc_idlist_del_server into server. Removes and
664 free's server entry from ID list.
666 * silc_server_private_message function now checks, if we are router,
667 that the destination ID really is valid ID, naturally.
669 * In router when NEW_ID packet is received (for new client) the
670 hash of the Client ID is saved in the ID Cache but the
671 client->nickname is set to NULL, instead of putting the hash
674 IDENTIFY command now also checks that client->nickname must be
675 valid. If it is not if will request the data from the server who
676 owns the client. Added new function
677 silc_server_command_identify_check.
679 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
680 to set the command to already allocated Command Payload.
682 * Tested private message sending in router environment with two
683 routers, two servers and two clients. Fixed minor bugs and now
686 * Fixed segfault from client's NAMES command. Used to crash if
689 * Forwarded packets must not be routed even if it is not destined
690 to the receiver. Changed server code comply with this.
692 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Added `require_reverse_mapping' boolean value to ServerParams
695 structure. If TRUE (not default) the server will require that
696 the connecting host has fully qualified domain name.
698 If the reverse mapping is not required and hostname could not be
699 found the IP address is used as hostname.
701 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Implemented version string checking to both client and server.
704 The check is incomplete currently due to the abnormal version
705 strings used in development version of SILC.
707 * Changed all command functions in server to use the new
710 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Changed char *data to unsigned char *data in ID Cache system to
713 support binary data as ID Cache data. Changed code to support
714 binary data in lib/silccore/idcache.c.
716 * Renamed silc_server_packet_relay_command_reply to
717 silc_server_command_reply as it is normal packet receiving
718 function. Rewrote the function to accept command replys for
719 servers and not only for clients.
721 * Mark remote router always as registered server if we are connecting
722 to it. Otherwise, commands sent by the router to us are ignored.
724 * All ID List find routines now returns the ID Cache Entry pointer
725 as well if requested.
727 * WHOIS command works now in router environment, tested with two
728 routers, two servers and two clients.
730 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
731 in router environment (as it is almost equivalent to WHOIS) but
732 hasn't been tested thoroughly. Added new functions:
734 silc_server_command_identify_parse
735 silc_server_command_identify_send_reply
736 silc_server_command_identify_from_client
737 silc_server_command_identify_from_server
739 * Disabled route cache adding because adding two different ID's with
740 same IP replaces the old cache entry thus giving wrong route.
741 The entry->router->connection is always the fastest route anyway
742 so route cache may not be needed. Of course, new routes maybe
743 established after receiving the ID when the entry->router->connection
744 might not be anymore the most optimal.
746 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Add route cache for received ID for fast routing.
750 * Added silc_server_packet_route to route received packet on router
751 that is not destined to us.
753 * Renamed silc_server_get_route to silc_server_route_get.
755 * Added id_string and id_string_len fields into SilcServer to
756 include encoded ServerID for fast comparing without excess
757 encoding of the ID's.
759 * Cleaned up WHOIS command on server side. Added following static
762 silc_server_command_whois_parse
763 silc_server_command_whois_check
764 silc_server_command_whois_send_reply
765 silc_server_command_whois_from_client
766 silc_server_command_whois_from_server
768 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
769 arguments in command replies. All command functions should be
770 updated to use this macro.
772 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Minor typo fixes on command reply handling on server.
776 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Added silc_server_command_add_to_channel internal routine to add
779 the client to the channel after router has created the channel and
780 sent command reply to the server.
782 * Added generic silc_server_send_command to send any command from
785 * Use static buffer with ID rendering instead of duplicating data.
787 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Fixed a channel user mode bug when joining to a channel server gave
790 everybody channel founder rights, oops.
792 * We mark ourselves as the router of the incoming server connection
793 if we are router ourselves. This way we can check in some packet
794 sending functions whether it is locally connected server. For
795 incoming router connections we put NULL.
797 * For router sending packets locally means now always sending the
798 packet cell wide; to local clients and local servers. For normal
799 server sending packet locally means sending it to only local
802 * Fixed the JOIN command to really work in router environment. If the
803 channel is created it is always created by the router. Router is
804 also responsible of making the initial joining to the channel,
805 sending JOIN notify to the sending server and distributing
806 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
807 does not exist server doesn't do anything else but forward the
808 command to the router which performs everything.
810 * Added silc_server_send_channel_key function to send the Channel Key
813 * Added silc_server_create_channel_key to create new channel key. The
814 channel key is now re-generated everytime someone joins or leaves
815 a channel, as protocol dictates. Note: channel->key_len is the
818 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Splitted server.[ch] finally. Created now packet_send.[ch] and
821 packet_receive.[ch] to separate packet sending and receiving
822 routines. The server.[ch] now includes everything else including
823 actual packet processing (writing and reading data) and other
826 Renamed silc_server_private_message_send_internal to
827 silc_server_send_private_message. The routine is still though
828 used only to relay private messages as server does not send
829 private messages itself.
831 Renamed silc_server_new_channel to silc_server_create_new_channel
832 and added new function sicl_server_new_channel that handles the
833 incoming New Channel packet. Added also new sending function
834 silc_server_send_new_channel to send New Channel Payload.
836 * Added new function silc_server_notify to process incoming notify
837 packet to the server/router. Server may then relay the notify
838 to clients if needed.
840 * Added new function silc_server_new_channel_user to process incoming
841 New Channel User packet. Router will redistribute the packet and
842 send JOIN notify to its local clients and locally connected servers
843 if needed. Normal server will send JOIN notify to its local client
844 on same channel when received this packet. Added also corresponding
845 sending function silc_server_send_new_channel_user to sent the
848 * Added boolean route argument to send_notif_to_channel and
849 packet_send_to_channel functions to attempt to route the packet
850 if it is TRUE and send only locally if it is FALSE.
852 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * silc_server_replace_id now broadcasts the received replace ID
855 packet if it is not broadcast packet already. The router must
856 broadcast to inform other routers about changed ID.
858 * Added backpointer to server's router into SilcServer context in
859 silcd/server_internal.h.
861 * Fixed silc_server_packet_broadcast to send correct broadcast
864 * The channel key is now distributed to the local client as soon
865 as it is received from the router (in router environment) so that
866 no other packet may be sent for the channel until client has
869 * silc_server_remove_channel_user now broadcasts the received
870 Remove Channel User packet if it is not broadcast packet already.
871 The router must broadcast to inform other routers about removed
874 * Added users field into SilcPacketContext that is a reference count
875 of the context. One can increase the reference count by calling
876 silc_packet_context_dup which is now changed to just increase the
877 reference count instead of duplicating the data. The reference
878 count is decresed by calling silc_packet_context_free that will
879 free the data after the reference count hits zero.
881 For now on the packet context and everything allocated into it
882 (including the raw packet from network) must be freed by calling
883 the new silc_packet_context_free function. Added also new function
884 silc_packet_context_alloc that must be used now to allocate the
885 context. This also means that if a routine is asynchronous from
886 silc_[client/server]_packet_parse_type the packet context must
887 be duplicated by calling silc_packet_context_dup. Otherwise it
888 gets free'd after silc_[client/server]_packet_parse_type returns.
889 Also, one must remember that if packet is duplicated then its
890 reference count must be decresed by calling the free function as
891 many times as it was duplicated.
893 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
894 from both client and server.
896 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Made joining to a channel working in router environment.
900 * Cleaned up JOIN command on server side and create function
901 silc_server_command_join_channel internal routine to make the
904 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Changed silc_command_pending list to SilcDList. Also, added
907 `ident' field to SilcServerCommandPending structure to identify
908 the reply and to call correct callback.
910 Added silc_server_command_pending_check function to replace the
911 corresnponding macro. The silc_command_pending list is not
914 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
915 to set identifier to previously allocated Command Payload. It
916 is used to set identifier for command when resending Command
919 * Added silc_command_payload_encode_payload to encode Command
920 Payload buffer from SilcCommandPayload structure.
922 * Added silc_argument_payload_encode_payload to encode Argument
923 payload buffer from SilcArgumentPayload structure.
925 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Changed WHOIS command to support router connection on server side.
928 The whois request is always sent to router unless the server is
929 standalone server. After server has received the reply from the
930 router will it send the reply to the client.
932 * Added silc_server_packet_broadcast into silcd/server.[ch] to
933 broadcast received broadcast packet. The function is used only
934 by router. The broadcast packet is always sent to the router's
937 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
938 render given ID to printable string, for log files for example.
940 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Made basic router to router connections working. At least they
943 can now connect to each other but nothing really works the way
944 they are supposed - yet.
946 * Added new initiator token to RouterConnection configuration
947 file in silcd/serverconfig.[ch]. It is used to tell whether we
948 are the initiator to the remote router or whether we'll expect
949 the other end to connect.
951 * Moved registering of listener task to silc_server_init, hence
952 the server starts listenning as soon as it is run, even if it
953 does not have connections to other routers. Let's see how well
956 * Changed default connection retry timeouts for more suitable in
959 * Removed cipher and such arguments from silc_idlist_add_client
960 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
961 Added new function silc_idlist_add_data to add the keys and stuff
964 * Added SilcIDListData structure and added it to SilcClientEntry
965 and SilcServerEntry as their first field in the structure. This
966 way we can explicitly cast the ID entries to the SilcIDListData
967 structure and get common data for the entries. In past, we had
968 to first check what type of connection it is and then cast it to
969 correct ID entry type. Now, we can directly cast the opaque
970 pointer to the SilcIDListData (no matter what ID entry it actually
971 is) and get the data needed.
973 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Wow, found a bug in scheduler. The scheduler uninitialized itself
976 in some circumstances even if threre were timeout tasks, though not
977 IO tasks, but tasks anyway. Now fixed.
979 * Defined SilcServerConnection structure to hold connection specific
980 stuff about directly connected servers and routers. The definition
981 is currently in silcd/server_internal.h. I thought about having
982 a bit more important role fro this struct but for now it is used
983 only when connecting to other server (or router actually).
985 * Added connecting retry support in server when connecting to
986 router(s). The retry feature implement exponential backoff
987 algorithm. Also, added SilcServerParams structure to hold default
988 parameters for server. For now, it include these retry settings
989 and are hard coded. After server is moded to be as Silc Server
990 Library this structure will be more important.
992 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Changed client librarys channel->clients table to SilcList and
995 changed code accordingly.
997 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Changed client's channel table to SilcList and changed code
1000 accordingly. Also changed SilcChannelClientEntry to include back-
1001 pointer to the channel so that client entry can use that structure
1002 as list as well and we have fast cross-reference to the channel.
1003 This change dramatically decreased the complexity of channel
1004 handling with client entry and vice versa (removed one extra
1005 loop when searching for channel entry from many functions).
1007 * Changed server->sim from table to SilcDList and changed code
1010 * NAMES command can now be used from user interface. It will show
1011 the user list on the channel, neatly.
1013 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1014 Code now saves realname of the user if it becomes available.
1016 * Renamed configure.in to configure.in.pre and made ./prepare
1017 script to automatically add correct version string to
1018 configure.in which it creates from configure.in.pre.
1020 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * NAMES command reply now shows users mode with the nickname when
1025 * Moved silc_client_ch[u]mode[_char] functions from
1026 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1027 place sucks, they are utility functions and should be in some
1030 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1032 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1035 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Added TRQ (efficient deque and list library) into lib/trq. This is
1040 a very good list library that is currently used in the SILC. Defined
1041 SilcList API over the library because I didn't like the API very
1042 much. See lib/trq/silclist.h for the API and examples of how to
1043 use the API. Fixed various places in the code to use the new
1044 SilcList API. The SilcList is meant for lists that has a structure
1045 already defined as a list. It is not suitable to add just some
1046 context to the list (in TRQ, the context is the list actually).
1048 So, I defined SilcDList that can be used for the purpose where
1049 predefined list structure does not exit. This can be used as
1050 such list. Now some context just can be added to the SilcDList.
1051 Currently this list is not used in the SILC just yet, though there
1052 are a lot places where this can replace dynamically allocated
1053 tables and I will fix these places, later, to use SilcDList.
1054 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1055 and use TRQ internally).
1057 Also fixed some annoying warning messages that the original TRQ
1058 code generated. Also minor changes to TRQ's Makefile.in.
1060 * Added support for querying by Client ID to both WHOIS and
1061 IDENTIFY commands into server, as required by the protocol.
1063 * Removed method function pointers from SilcBuffer structure. They
1064 weren't used to anything and just increased the context size for
1065 no good reason. This change also made silc_buffer_alloc and
1066 silc_buffer_free functions inline functions.
1068 * Disabled command flooding detection support until it's fixed so
1069 that it accepts commands in but does not execute them more than once
1072 * Added silc_net_localhost(), to return local hostname, into
1073 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1074 that must be initialized before calling silc_client_init.
1076 * Added new function: silc_server_send_notify_on_channels to send
1077 notify messages to all channels client has joined. It is assured
1078 that the message is sent only once per client.
1080 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1081 lib/silcutil/silcutil.[ch] as silc_format function. The new
1082 function is generic and is used by server as well, not only by
1083 the logging routines.
1085 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1086 the provided version string was not acceptable. Added new function:
1087 silc_ske_check_version into lib/silcske/silcske.h. The function
1088 must be implemented by the application (client or server) and it
1089 does not reside in the SKE library. The function checks the version
1090 string remote end sent.
1092 * Added back pointers (to opaque context and to SilcSocketConnection)
1093 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1095 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1096 duplicate packet context structure.
1098 * Changed `notify' client operation to send same arguments as client
1099 receives from server except for ID's. ID's are mapped to correct
1100 ID entry and that is returned. Also, if channel entry is not sent
1101 by server but the notify is for channel the channel entry is sent
1102 to application (otherwise application doesn't know that it is for
1103 channel (library gets it from packet's Destination ID)).
1105 * Added silc_client_remove_from_channels into client library to
1106 remove a client from all channels it has joined to. Used when
1107 received SIGNOFF notify from server. Added also new function
1108 silc_client_replace_from_channels to replace old ID entry with
1109 new ID entry on all channels. Used when received NICK_CHANGE
1112 * Fixed ID Cache list handling in silc_idlist_get_client in
1113 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1114 to get (or query) client by ID.
1116 * Updated TODO list.
1118 * Added connection authentication status message defined by the
1119 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1120 support for these into the code in client and server side.
1122 * Added generic function silc_client_send_command to send any command
1123 with variable argument list. Application should use this function
1124 to send commands if the command functions provided by the library
1125 does not suite for the application's user interface needs.
1127 * Added new `failure' client operation. Application is notified about
1128 received failure packet if client is executing a protocol. In this
1129 case the protocol's execution has failed.
1131 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1132 is required by the protocol.
1134 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1135 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1138 * Added status flag to SilcSKE object to indicate realtime status
1139 of the SKE protocol.
1141 * Application receives now exactly same command reply arguments as
1142 the library receives from server. However, if ID is received the
1143 corresponding ID entry is returned to the application (eg. Client
1144 ID is mapped to correct SilcClientEntry entry and that is returned).
1145 Changed command_reply client operation due to this change.
1147 * Changed all ID's in commands and in command replys as ID Payloads.
1148 Change affected both client and server side codes.
1150 All ID's sent in SILC network (with execption of ID's in SILC
1151 Packet header) are sent in ID Payload to support variable length
1154 * Server now notifies nick changes and notifies all clients on
1155 the channels about the new nickname (about the new Client ID,
1158 * Implemented CMODE command to change channel modes. Supports all
1159 channel modes defined by the protocol specs except ban and invite
1160 lists. (Also, private channel key mode is supported but support for
1161 setting private channel key in client is missing, thus, this mode
1162 has no effect on client side (except that server requires that the
1163 client uses private channel key and normal channel traffic does not
1166 Also, invite mode works per se, but INVITE command does not work
1167 yet correctly, so you can set channel as invite only channel but
1168 inviting clients to the channel does not work (it is yet to be
1169 thought what's the best way to do it).
1171 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1172 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1173 Implemented CUMODE command to change user's mode on the channel.
1174 Supports all modes defined by the protocol specs.
1176 * Added NAMES command reply to return users modes on the channel.
1178 * Removed unnecessary and slow ciphers from lib/silccrypt.
1180 * Set SO_KEEPALIVE option to connection sockets by default.
1182 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1184 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1185 redefined the Notify Payload into protocol specs.
1187 * Added silc_id_payload_parse_id to get ID directly from raw
1190 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1193 accept searching by Client ID as well.
1195 * Added support for LEAVE and SIGNOFF notify types in client library.
1197 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1198 to parse ID Payload from raw data.
1200 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Added flags parameter into silc_ske_assemble_security_properties
1203 function in lib/silcske/silcske.[ch].
1205 * Changed notify client operation to fit better for notify messages
1206 sent by server. The notify payload received from server is now
1207 passed to the application (after parsing it to SilcNotifyPayload).
1208 It is application's responsibility to retrieve the arguments
1209 from the payload and show the message the way it wants. The message
1210 sent by server is implementation specific.
1212 * Changed public keys to comply with the protocol specification.
1213 Old public keys are not supported anymore and are not compatible.
1215 * Removed nickname from Channel Payload as the latest draft removed
1216 it. The client must resolve the nickname from the NAMES command
1217 reply received when it joined the channel.
1219 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1221 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Fixed some errors in protocol specification drafts.
1225 * Created lib/silccore/silcnotify.c to implement Notify Payload
1226 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1227 generic payloads described by protocol specifications. The file
1228 includes implementations for ID Payload and Argument Payload.
1230 * Changed Command Payload implementation to use the new Argument
1231 Payload. Changed command_xxxx_payload to command_payload_xxxx
1232 to comply with SILC coding conventions.
1234 * Added suppport for Argument Payload handling in Notify Payload
1235 implementation as protocol requires it. Added the new support
1236 into server and client lib as well.
1238 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added support for multiple nicknames on same channel. [n] is
1241 added locally to the nickname if there are more than one same
1242 nicknames on the channel.
1244 * Server now sends all nicknames that matched WHOIS request.
1245 Client also shows the list received from server.
1247 * Added TOPIC command to client side. User can now set and show
1248 current topic on channel.
1250 * Added MOTD command to client and server. Also, server sends the
1251 motd when client connects to the server.
1253 * Changed version strings to comply ISO 8601.
1255 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * Fixed protocol error handling in client library. It should now
1258 cope even if the SKE fails for some reason.
1260 * Made new protocol specification drafts for submitting to IETF.
1262 * Implemented TOPIC command to server in silcd/command.c.
1264 * Added two new notify types into lib/silccore/silcnotify.h:
1265 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1266 notify nickname change and topic setting/change on a channel.
1268 * API change of command_reply operation in client library. The
1269 application gets now the status type received from server as well.
1271 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1275 * Cras fixed and optimized the packet handling even further and
1276 it should work now. Minor change to the prototype of function
1277 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1279 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Added new function into lib/silcutil/silcschedule.[ch]:
1282 silc_schedule_with_fd to select() a specified fd. The function
1283 returns after timeout expires or data arrives or goes. The
1284 function is used by packet routines to wait that all data is
1285 received from network.
1287 * Fixed data reading from network in lib/silccore/silcpacket.c.
1288 The code now assures that all data is read from the fd and then
1289 continues packet processing. This was a bug fix since the code
1290 used to drop some data in some circumstances.
1292 * Added new function into lib/silcclient/client.[ch]:
1293 silc_client_start_key_exchange to start key exchange after
1294 connection has been established to server. The code internally
1295 now uses this funtion but its main purpose was to provide it
1296 for applications that perform their own connecting. After
1297 application has created a connection it merely calls this
1298 function to start the key exchange between client and server.
1299 The library takes care of everything else after that.
1301 Updated also lib/silcclient/README to explain the usage of
1304 * Do not send to application information that connection has
1305 been established. Application gets notified it by connect
1308 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Applied cras's patch to add silc_schedule_one function. The
1311 function runs scheduler once and returns.
1313 * Fixed the scheduler after cras messed it up. The timeout
1314 handling works now as it's supposed to work.
1316 * Added into lib/silccore/ silcnotify.h to include notify
1317 message types support. Changed silc_server_send_notify*
1318 functions, in server.[ch], to support those new notify types.
1319 Added the support for the notify types into client library,
1320 as well. Added new notify client operation into ops.h in
1323 * Changed silc_server_packet_send_to_channel to send normal
1324 packets instead of just channel message packets. The function
1325 is now used to send the notify packets to channels. It is not
1326 used to send channel message packets anymore, as server never
1329 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1330 va_arg()s as it seems to require it nowadays. I guess, if SILC
1331 is compiled with older va_arg() the new code should work anyway.
1333 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Splitted core library. Core library (lib/silccore) includes
1336 now only SILC protocol specific core (and common) components.
1337 Created new utility library (lib/silcutil) that includes more
1338 generic purpose stuff. The stuff for util library was taken
1339 from the old core library. This was minor and easy split.
1341 * Created SILC Client Library (lib/silcclient) that includes
1342 implementation of the SILC client without user interface. This
1343 was major move from silc/ directory. The code has been changed
1344 so that it is transparent towards the user interface. The
1345 silc/ directory includes now the same user interface as before
1346 and it uses the new client library. Read lib/silcclient/README.
1347 Basicly, the client library performs everything else related
1348 to SILC except user interface handling. Also, configuration
1349 files are considered to be part of user interface and library
1350 does not handle them.
1352 This change also changed a lot of structures, function naming etc.
1353 Most important change was that SilcClientWindow object was
1354 renamed to SilcClientConnection in the client library. Created
1355 also new file lib/silcclient/ops.h. Also added new files
1356 silc/local_command.[ch] and silc/client_ops.[ch].
1358 All these changes were made to make it easier for user interface
1359 designers to create what ever user interface for the SILC client
1362 It is also expected that the server will be moved to lib
1363 directory as well and SILC Server Library will be created;
1364 sometimes in the future.
1366 * Removed Local commands from lib/silccore/silccommand.h as
1367 they are application specific and new client library does not
1368 handle any of those anymore.
1370 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1371 old client implementation in silc/.
1373 * Added support for callback functions in SILC_LOG_* macros.
1374 Application can now set its own callbacks that will be called
1375 instead of using the default functions that will always print
1376 the debug messages to stderr (or stdout). Also, debugging can
1377 now be disabled by setting silc_debug to FALSE and re-enabled by
1378 setting it to TRUE. Note, that logging will still work even
1379 if debugging is disabled.
1381 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1382 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1383 silc_log_reset_debug_callbacks.
1385 * To enable debugging in silc client one must give now -d
1386 option on command line.
1388 * Changed silc_schedule_init to automatically allocate task queues
1389 if they are not allocated before calling it.
1391 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Added GMP 3.1 into math library.
1395 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1398 a channel in SILC network. The packet is used by servers and
1399 routers to notify other routers that user has left a channel.
1400 This little feature was missing until now. Added the feature
1401 to protocol specification as well.
1403 Added functions: silc_server_send_remove_channel_user and
1404 silc_server_remove_channel_user into server.[ch].
1406 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1407 lib/silccore/silcpacket.h. However, they are not implemented
1410 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Fixed joining to a channel and sending channel messages
1413 between server and router. The channel message sending should
1414 now work inside a cell.
1416 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Fixed the private message sending between server and router.
1419 The private message sending should now work inside a cell.
1421 * Added silc_server_replace_id into server.[ch] to replace
1422 existing ID in the SILC network.
1424 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1425 and silc_idlist_replace_server_id into idlist.[ch] in server.
1427 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Fixed the server to server connections. Server can again now
1430 connect to router. Router to router connections probably does
1433 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Added dynamic protocol registering support. Now protocols can
1436 registered and unregistered on the fly. Patch by cras.
1438 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Added lib/contrib directory to hold routines that some platforms
1441 don't have but are needed by SILC.
1443 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1444 into lin/contrib to provide getopt() and getopt_long() for
1445 those who don't have it.
1447 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Added AWAY command to client. When away message is set and
1450 client receives a private message packet the client automatically
1451 replies to the sender with the away message.
1453 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1454 bug seemed to be the cause of recent problems when compiling
1457 * Added version detection support to SKE protocol specification
1458 and added the new changes to the SKE implementation as well.
1459 There were other minor changes in the SKE protocol as well.
1461 Many changes in lib/silcske/silcske.[ch] and in
1462 lib/silcske/payload.[ch].
1464 * Added ^U functionality, clear input line. Patch from cras.
1466 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Mainly small bugfixes on core library. Fixed some debugging
1469 logging and buffer overflow in silclog.c.
1471 * Updated config.sub and config.guess on the distribution tree.
1473 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Added command lagging support in server. Client may execute
1476 commands now only once in two seconds.
1478 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * Optimized packet reception. MAC computation and checking is now
1481 also more optimized. A lot previously duplicated code is now
1482 used as generic by both client and server.
1484 * Fixed key pair generation in clientutil.c
1486 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added into lib/silccore/silcbufutil.[ch] new function;
1489 silc_buffer_realloc.
1491 * Moved generic packet sending/encryption functions to
1492 lib/silccore/silcpacket.[ch] from client and server. Some
1493 rewriting of the functions.
1495 * Moved all generic packet reception/decryption functions to
1496 lib/silccore/silcpacket.[ch] from client and server. The
1497 packet processing is now much cleaner in both client and server.
1498 These were major changes in both client and server.
1500 * Created many common functions in server to do packet sending.
1501 Previously code were duplicated a lot, this has been removed
1504 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Rewrote major parts of the ID cache system. Don't know
1507 whether it is better now or not but at least the API is more
1510 * Major rewrite on ID cache stuff on client because of the ID
1511 cache API changes. Added idlist.c to client.
1513 * Also major rewrite on ID cache stuff on server as well.
1514 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1515 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1516 in hand, instead they are all put into the ID cache system now.
1517 All server_idlist_* routines uses ID cache now instead of
1518 traversing its own lists (those lists does not exist anymore).
1519 SilcIDList though still exists. Also, SilcXXXEntry's are
1522 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1524 * Finally made the SKE implementation compliant to the protocol
1525 specification. All mp integers are now binary encoded as
1526 opposed being HEX encoded.
1528 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1531 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1532 functions: silc_[encode/decode]_pem. Also added function
1533 silc_encode_pem_file to PEM encode with newlines ('\n') for
1536 * SILC public keys are now encoded either PEM or binary. Same
1537 option is for private keys as well. By default private keys
1538 are binary encoded and public keys PEM encoded. Silly HEX
1539 encoding were removed.
1541 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1542 function to create fingerprints.
1544 * Fixed a bug in SHA1; does not change the original data anymore.
1546 * Partly implemented INFO command on client and server side.
1547 Fixed CLEAR command. Changes to SERVER command; show current
1548 server(s) when giving command without arguments. Added
1549 VERSION command to client.
1551 * Added check to server that unregistered connections cannot
1552 execute commands (unless it is specificly allowed).
1554 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Fixed screen refresh.
1558 * Fixed channel joining bug from client. On some circumstances
1559 client tried to join to a channel it had already joined.
1561 * Added public key verification process into client's protocol.c.
1562 The client now verifies the public key from user and saves
1563 it into ~./silc/serverkeys/ directory.
1565 Added into: clientutil.[ch]: silc_client_verify_server_key.
1567 * Changed SKE protocol's silc_ske_initiator_finish function
1568 to accept callback function that verifies the received public
1569 key. Removed old silc_ske_verify_public_key function.
1571 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1574 silc_pkcs_private_key[_data]_set.
1576 * Made the password and public authentication more cleaner in
1577 server's protocol.c.
1579 * Removed historic and obsolete protocol `channel_auth' from
1580 both client and server.
1582 * Removed wrong way of sending command status messages from
1583 server to client in server's command.c. The old way violated
1584 protocol specification.
1586 Changes to silccore/silccommand.[ch]: removed
1587 silc_command_encode_status_payload -> not needed anymore,
1588 changed silc_command_encode_payload_va to accept extra
1589 argument on variable argument list. The argument type must
1590 now be provided to the function. Also, added new function:
1591 silc_command_encode_reply_payload_va which is same as
1592 normal command_encode_payload_va except command status type
1593 is provided as extra argument.
1595 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * Added ~./silc directory handling. The directory includes the
1598 public and private keys for the client.
1600 Added silc_client_check_silc_dir, silc_client_create_identifier
1601 and silc_client_load_keys.
1603 * Implemented SILC protocol compliant public key. Added public
1604 and private key saving to and loading from files.
1606 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1607 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1608 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1609 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1610 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1612 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1613 silc_pkcs_load_[public/private]_key.
1615 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Added silc_server_get_route (route.[ch]) to get connection
1618 data for the fastest route for given ID.
1620 * Implemented INVITE command on client and server. The command
1621 were re-defined in the SILC Protocol Specification and the
1622 implementation now complies with the specification.
1624 * Implemented PING command on client and server.
1626 * Implemented NAMES command on client and server. The server side
1627 supports currently only normal server not router server yet.
1628 Some changes to NAMES definition in SILC protocol specification.
1630 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Implemented LEAVE command on client and server.
1634 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1635 again. This change was made to the protocol as well. Server
1636 should not violate the protocol specification anymore.
1638 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1641 was tested. SOCKS4 was not but should work anyway.
