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 * Defined Authentication Payload into protocol specification that
29 is used during SILC session to authenticate entities. It is
30 used for example by client to authenticate itself to the server
31 to obtain server operator privileges.
33 Implemented this payload into the lib/silccore/silcauth.[ch].
34 Implemented also routines for public key based authentication
35 as the new protocol specification dictates.
37 Moved definitions of different authentication methods from
38 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
40 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
41 silc_pkcs_verify and silc_pkcs_sign_with_hash and
42 silc_pkcs_verify_with_hash functions into the file
43 lib/silccrypt/silcpkcs.[ch].
45 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * The client entry's userinfo pointer must be always valid.
48 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
49 will fail since it requires the userinfo. Now, the userinfo
50 is allocated as "" if actual userinfo does not exist. Actually,
51 it must exist and it is totally Ok to drop client connections
52 that does not announce the userinfo. However, we will make
53 this workaround for now.
55 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
56 to return the remote port by socket.
58 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
60 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
61 SILC_SERVER_PENDING_EXEC and added an new macro
62 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
63 data or when error occurs while processing the pending command.
65 Added new argument `destructor' into silc_server_command_pending
66 and to the SilcServerCommandPending object. This destructor is
67 now called after calling the pending callback or if error occurs
68 immediately. If error occurs the actual pending callback won't
69 be called at all - only the destructor. The destructor may be
70 NULL if destructor is not needed.
72 All this applies for client library code as well. Similar
73 changes were made there as well for the pending commands.
75 In the client, the application must now allocate the
76 SilcClientCommandContext with the silc_client_command_alloc
79 * Added reference counter to the SilcServerCommandContext. Added
80 function silc_server_command_alloc and silc_server_command_dup
83 Same type of functions added to the client library for the same
86 * Removed the cmd_ident from IDListData away since it is now
87 global for all connections. It is the command identifier used
88 in command sending and with pending commands. The affected file
91 * Added reference counter to the SilcSocketConnection objecet to
92 indicate the usage count of the object. The object won't be
93 freed untill the reference counter hits zero. Currently only
94 server uses this, and client ignores it. The client must be
95 set to use this too later. The affected files are
96 lib/silccore/silcsockconn.[ch]. Added also the function
97 silc_socket_dup to increase the reference counter.
99 This was mainly added because it is possible that the socket
100 is removed underneath of pending command or other async
101 operation. Now it won't be free'd and proper DISCONNECTING
102 flags, etc. can be set to avoid sending data to connection that
103 is not valid anymore.
105 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
106 the connection. After that it sets SILC_SET_DISCONNECTED.
107 It is, however, possible that the socket data is not still freed.
108 The silc_server_packet_process now checks that data is not
109 read or written to connection that is DISCONNECTED. The socket
110 get's freed when the reference counter hits zero.
112 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
114 * Changed the client operation API: channel_message operation's
115 `sender' is now the client entry of the sender, not the nickname
116 and the `channel' is the channel entry, not the channel name.
118 In the private_message operation the `sender' is now also the
119 client entry of the sender not the nickname.
121 Affected file is lib/silcclient/ops.h and all applications
122 using the client operations.
124 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Moved the calling of ops->connect() from connect_to_server_final
127 into receive_new_id functin since that is the point when the
128 client is actually allowed to send traffic to network. The
129 affected file is lib/silcclient/client.c.
131 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
134 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
135 (if needs broadcasting) instead of broadcasting the packets one
136 by one which would make a burst in the network traffic.
138 * Added `broadcast' argument to the functions in silcd/server.[ch]
139 silc_server_create_new_channel[_with_id] to indicate whether
140 to send New Channel packet to primary router.
142 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Added new function into the silcd/server.[ch] files:
145 silc_server_create_new_channel_with_id to create new channel with
146 already existing Channel ID.
148 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
149 lib/silccore/silcpacket.h. This packet is used t send list of
150 Set Mode payloads inside one packet. Server uses this to set
151 the modes for the channels and clients on those channels, that it
152 announced to the router when it connected to it. The protocol
153 specification has been updated accordingly.
155 * The silc_server_new_channel did not handle the packet coming
156 from normal server as it normally does not send that. However,
157 when it announces its channels it does send it. Implemented
158 the support for that.
160 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
161 into the file lib/silccore/id.h.
163 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Fixed memory leaks in the functions silc_idlist_del_client,
166 silc_idlist_del_channel and silc_idlist_del_server in the file
167 silcd/idlist.c. All of those leaked like a sieve.
169 * Fixed some small memory leaks in the client's function
170 silc_client_notify_by_server.
172 * Added functions into silcd/server.c: silc_server_announce_clients,
173 silc_server_announce_channels and silc_server_announce_server.
174 These functions are used by normal and router server to announce
175 to its primary router about clients, channels and servers (when
176 router) that we own. This is done after we've connected to the
179 These functions effectively implements the following packet types:
180 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
181 and SILC_PACKET_NEW_ID_LIST.
183 * Added new functions into the silcd/packet_receive.[ch]:
184 silc_server_new_id_list, silc_server_new_channel_list and
185 silc_server_new_channel_user_list to handle the incoming
186 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
188 * Added support of changing Channel ID in the function
189 silc_server_replace_id. If the server that announces a channel
190 to the router already exists in the router (with same name but
191 with different Channel ID), router is responsible to send
192 Replace ID packet to the server and force the server to change
193 the Channel ID to the one router has.
195 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
196 client that the Channel ID has been changed by the router. The
197 normal server sends this to the client. Client must start using
198 the new Channel ID as the channel's ID.
200 Implemented handling of this new type into lib/silcclient/client.c
201 into the function silc_client_notify_by_server.
203 * Added new function silc_idlist_replace_channel_id into the files
204 silcd/idlist.[ch] to replace the Channel ID.
206 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Call silc_server_command_identify_check always when processing
209 the IDENTIFY command in silcd/command.c
211 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
214 send keepalive packets. The packet can be sent by clients,
217 Added function silc_socket_set_heartbeat into the file
218 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
219 If not set, the heartbeat is not performed. The actual
220 heartbeat is implemented in the low level socket connection
221 library. However, application is responsible of actually
224 Added silc_server_send_heartbeat to send the actual heartbeat
225 packet into silcd/packet_send.[ch]. Server now performs
226 keepalive with all connections.
228 * Added silc_task_get_first function into lib/silcutil/silctask.c
229 to return the timeout task with shortest timeout. There was a bug
230 in task unregistration that caused problems. TODO has been
231 updated to include that task system must be rewritten.
233 * The client library will now resolve the client information when
234 receiving JOIN notify from server for client that we know but
235 have incomplete information.
237 * Rewrote parts of silc_server_remove_from_channels and
238 silc_server_remove_from_one_channel as they did not remove the
239 channel in some circumstances even though they should've.
241 * Encryption problem encountered in server:
243 The LEAVE command used to send the Channel Key packet to the
244 router immediately after generating it. However, the code
245 had earlier sent Remove Channel user packet but not immediately,
246 ie. it was put to queue. The order of packets in the router
247 was that Channel Key packet was first and Remove Channel User
248 packet was second, even though they were encrypted in the
249 reverse order. For this reason, MAC check failed. Now, this
250 is fixed by not sending the Channel Key packet immediately but
251 putting it to queue. However, this is more fundamental problem:
252 packets that are in queue should actually not be encrypted
253 because packets that are sent immediately gets encrypted
254 actually with wrong IV (and thus MAC check fails). So, packets
255 that are in queue should be encrypted when they are sent to
256 the wire and not when they put to the queue.
258 However, the problem is that the current system has not been
259 designed to work that way. Instead, the packet is encrypted
260 as soon as possible and left to the queue. The queue is then
261 just purged into wire. There won't be any fixes for this
262 any time soon. So, the current semantic for packet sending
265 o If you send packet to remote host and do not force the send
266 (the packet will be in queue) then all subsequent packets to the
267 same remote host must also be put to the queue. Only after the
268 queue has been purged is it safe again to force the packet
271 o If you send all packets immediately then it safe to send
272 any of subsequent packets through the queue, however, after
273 the first packet is put to queue then any subsequent packets
274 must also be put to the queue.
276 Follow these rules and everything works fine.
278 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Added new function silc_server_remove_clients_by_server to
281 remove all client entries from ID list when the server connection
282 is lost. In this case it is also important to invalidate all
283 client entires as they hold the invalid server entry. This
284 fixes fatal bug when server has lost connection and will reconnect
287 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Made some sanity checks to silc_server_daemonise like to check
290 whether the requested user and group actually exists.
292 * Added sanity check to SKE's silc_ske_responder_finish to check
293 that the public and private key actually is valid.
295 * Invalidate the client's nickname when receiving Replace ID
296 packet and the Client ID is being replaced. This means that the
297 server will query the nickname if someone needs it (client)
300 * Sort the ID Cache in client library when the ID Cache data
301 has changed (needs sorting).
303 * Do not allow for SILC client to create several connections to
304 several servers. The client does not support windows right now
305 and generating multiple connections causes weird behaviour.
307 Irssi-silc client does support windows and can handle several
308 connections without problems, see: www.irssi.org and SILC plugin.
310 * Fixed some places where client was added to the IDList. The
311 rule of thumb is following (in order to get everything right):
312 If the client is directly connected local client then the
313 `connection' argument must be set and `router' argument must be
314 NULL to silc_idlist_add_client function. If the client is not
315 directly connected client then the `router' argument must
316 bet set and the `connection' argument must be NULL to the
317 silc_idlist_add_client function.
319 * The funtion silc_server_packet_send_local_channel actually did
320 not check whether the client was locally connected or not. It
321 does that now. Fixed a bug related to LEAVE command.
323 * Fixed Remove Channel User payload parsing bug in server's
324 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
326 * The server's silc_server_save_channel_key now checks also the
327 global ID list for the channel as it might not be in the local
328 list. Fixed a bug related to LEAVE command.
330 * Is this the end of the [<unknown>] buglet that has been lurking
331 around for a long time? A little for loop fix in server's
332 silc_server_command_whois_parse that is used by both IDENTIFY
333 and WHOIS command. At least, this was a clear bug and a cause
334 of one type of [<unknown>] buglet.
336 * WHOIS and IDENTIFY commands call the function
337 silc_server_command_[whois/identify]_check function even if
338 we are not router server.
340 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Added --with-gmp configuration option. If set the GMP
343 is always compiled in the SILC source tree. If not set then
344 it is checked whether the system has the GMP3 installed. If
345 it has then the GMP won't be compiled (the system's headers
346 and library is used), if it doesn't have it then the GMP is
347 compiled in the SILC source tree.
349 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Changed RSA private exponent generation to what PKCS #1
352 suggests. We try to find the smallest possible d by doing
353 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
354 not security fix but optimization.
356 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added new config entry [Identity] to fork the server and run
359 it as specific user and group. A patch from Bostik.
361 * Imported Dotconf configuration library into lib/dotconf.
362 This will be used to create the SILC configuration files later.
363 It will appear in the distsribution after this commit.
365 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * A big code auditing weekend happening. Auditing code for
368 obvious mistakes, bugs and errors. Also, removing any code
371 Removed files for being obsolete:
373 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
374 inline in the file lib/silcutil/silcbuffer.h)
376 o lib/silcutil/silcbufutil.c (the header has inline versions)
378 Changed code to fix possible error conditions:
380 o The buffer formatting routines now check that the destination
381 buffer really has enough space to add the data. This applies for
382 both buffer formatting and unformatting
383 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
384 unformatting was changed to accomodate following rules:
385 XXX_*STRING_ALLOC will allocate space for the data into the pointer
386 sent to the function while XXX_*STRING will not allocate or copy
387 the data into the buffer. Instead it sets the pointer from the
388 buffer into the pointer sent as argument (XXX_*STRING used to
389 require that the pointer must be allocated already). This change
390 makes this whole thing a bit more consistent and more optimized
391 (note that the data returned in the unformatting with XXX_*STRING
392 must not be freed now). The routines return now -1 on error.
394 o Tried to find all code that use buffer_format and buffer_unformat
395 and added return value checking to prevent formatting and
396 especially unformatting errors and possible subsequent fatal
399 o Changed ske->x and ske->KEY to mallocated pointers in
400 lib/silcske/silcske.h. Fixed possible data and memory leak.
402 o Added return value checking to all *_parse* functions. Fixed
403 many memory leaks as well.
405 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
406 so that buffer overflows would not happen. All code now also
407 checks the return value as it can fail.
409 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Added reconnection support to server if the normal server looses
412 its connection to the router (for example if router is rebooted).
413 The server performs normal reconnection strategy implemented
414 to the server. Affected file silcd/server.c.
416 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
418 * Added new packet type SILC_PACKET_SET_MODE that is used to
419 distribute the information about changed modes (for clients,
420 channels and clients channel modes) to all routers in the
421 network. Updated the protocol specification accordingly.
423 Added functions into silcd/packet_send.c and
424 silcd/packet_receive.c: silc_server_send_set_mode,
425 silc_server_set_mode.
427 Added new files silcmode.[ch] into lib/silccore that implements
428 the encoding and decoding of Set Mode Payload. Added new type
429 SilcSetModePayload. Moved the definitions of different modes
430 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
432 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
434 * Oops, a little mistake in server's connection authentication
435 protocol. The protocol is not ended with FAILURE but with
436 SUCCESS if the authentication is Ok. :) Affected file is
439 * Implemented NICK_CHANGE notify handling in server in the file
440 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
441 the local clients on the channel. After the changing nickname
442 in router environment snhould work and the [<unknown>] nickname
443 should appear no more.
445 The silc_server_replace_id function that receives the Replace ID
446 payload now sends the NICK_CHANGE notify type also in the file
447 silcd/packet_receive.c
449 * Changed WHOIS and IDENTIFY command to support the maximum amount
450 of arguments defined in protocol specs (3328 arguments). This
451 fixed a bug that caused problems when there were more than three
454 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Added extra parameter, command identifier, to the
457 silc_client_send_command so that explicit command identifier
460 Changed that ID list routines uses specific command identifier
461 when sending WHOIS/IDENTIFY requests to the server so that they
462 can be identified when the reply comes back.
464 Affected files lib/silcclient/command.[ch],
465 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
467 * Added `sender' argument to silc_server_packet_send_to_channel
468 to indicaet the sender who originally sent the packet to us
469 that we are now re-sending. Ignored if NULL. Affected file
470 silcd/packet_send.[ch].
472 * Added some server statistics support in silcd/server_internal.h
473 SilcServerStatistics structure and around the server code. Also
474 send some nice statistics information when client is connecting
477 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Fixed channel ID decoding in server's JOIN command reply in
480 silcd/command_reply.c
482 * Fixed braodcasting of replace ID payload to not to send it if
483 we are standalone server in silcd/packet_receive.c.
485 * Fixed all channel message sending routines to not to send
486 packets to clients that has router set, since they are routed
487 separately in the same function earlier. Affects file
488 silcd/packet_send.c and all channel packet sending functions.
490 * In USERS reply, res_argv[i] are not allocated, the table
491 is allocated. Thus changed that free the table, not its
494 * In server's whois_check and identify_check if the client is
495 locally connected do not send any WHOIS commands - they are not
498 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Fixed some minor bugs in client when sending WHOIS command. The
501 arguments was in wrong order.
503 * Removed statis function add_to_channel from server in
504 silcd/command.c that was previously used with the joining but
507 * Tested USERS command in router environment successfully with two
508 routers, two servers and two clients.
510 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Reorganized the USERS command and command reply in client library
513 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
514 When the command is given by user we register a pending command
515 callback that will reprocess the command after the reply has been
516 received from the server. When reprocessing the packet we then
517 display the information. Thus, the USERS information is displayed
518 now in the command callback instead of in the command reply
519 callback. The processing of the command is same as previously
520 when server has sent the command reply in the JOINing process.
522 * Added to USERS command in silcd/command_reply.c to join the client,
523 we didn't use to know about, to the channel after we've created
524 a client entry for it. Also, for clienet we did know already still
525 check whether it is on the channel or not and add it if not.
527 * Removed silc_server_command_join_notify as the function and its
530 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Changed the client's pending command handling to the same as the
533 server's pending command handling. It is also now possible to
534 execute command reply functions from other command reply
535 function as the function callbacks for commands and command
536 replies are one and same. The pending commands are not static
537 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
538 in client connection context. Thus, pending commands are server
539 connection specific as it is convenient.
541 Changed the function silc_client_command_pending and
542 silc_client_command_pending_del and added new function
543 silc_client_command_pending_check. Removed the
544 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
547 * Added cmd_ident, current command identifier, to the client
548 connection context in lib/silcclient/client.h to keep track on
549 command identifiers used in command sending. Client's command reply
550 function handling now supports the mandatory command identifiers.
552 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
553 funtions in client to fully support pending command callbacks.
555 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
556 as one of the arguments to the application in the command reply
559 * NOTE: The FORWARDED flag is depracated. It used to be depracated
560 before first releasing SILC but came back. Now it is removed again
561 and should come back nomore. The FORWARDED flag was used only
562 by the JOINing procedure by forwarding the command packet to router.
563 Now, the JOINing procedure has been changed to more generic (due
564 to various router environment issues) and FORWARDED is not needed
565 anymore for anything. The protocol specification is yet to be
568 Now, removed silc_server_packet_forward from server and the flag
569 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
571 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
573 * Renamed NAMES command to USERS command. The NAMES was named that
574 due to historical reasons. Now it is renamed. Also, rewrote
575 parts of the USERS command. The nickname list is not sent anymore
576 by the server. Only Client ID and mode lists are sent in the USERS
577 command. Changed this also to the protocol specification.
579 The client now resolves the names and stuff after it receives
580 the USERS list from the server when joining to the channel.
582 * WHOIS and IDENTIFY commands has been changed to support multiple
583 Client ID's per command. One can now search for multiple users
584 in the network by sending only one WHOIS or IDENTIFY command.
585 Changed the code and the protocol specifications.
587 * Removed silc_server_command_identify_parse and changed that IDENTIFY
588 uses silc_server_command_whois_parse to parse the request. */
590 * If normal server, do not parse the WHOIS and IDENTIFY requests
591 before sending it to the router. Saves some time.
593 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Fixed JOIN command on client library. Wrong number of arguments
596 used to crash the client.
598 * Added silc_server_channel_has_global function to check whether
599 channel has global users or not.
601 * Added silc_server_channel_has_local function to check whether channel
602 has locally connected clients on the channel.
604 * The silc_server_remove_from_one_channel now checks whether the
605 channel has global users or not after given client was removed from
606 the channel. It also checks whether the channel has local clients
607 on the channel anymore. If it does not have then the channel entry
608 is removed as it is not needed anymore.
610 * The silc_server_notify now checks on JOIN notify whether the joining
611 client is one of locally connected or global. If it is global then
612 the channel has now global users on the channel and that is marked
613 to the channel entry. Also, it now saves the global client to
614 global list who is joining and JOINs it to the channel. This is
615 for normal server, that is.
617 Changed silc_server_send_notify_on_channel,
618 silc_server_packet_relay_to_channel and
619 silc_server_packet_send_to_channel check if we are normal server
620 and client has router set (ie. global client) do not send the
621 message to that client, as it is already routed to our router.
623 * Implemented LEAVE notify type handling in silc_server_notify
626 * Tested LEAVE command in router environment successfully. Tested
627 with two routers, two servers and two clients.
631 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
633 * Implemented SIGNOFF notify type handling in silc_server_notify
636 * silc_server_remove_id now removes the client entry from all channels
637 it has joined and thusly sends SIGNOFF notify type.
639 * Rewrote the NAMES list generation in server by removing two excess
640 loops. The lists are created now inside one loop.
642 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * silc_server_remove_channel_user checks now also global list
645 for channel and client.
647 * silc_server_new_channel_user checks now both local and global
648 list for channel and client. Fixed a bug in client id decoding.
649 Used to decode wrong buffer.
651 * silc_server_channel_message checks now both local and global
652 list for channel entry.
654 * Tested channel joining (hence JOIN) in router environment
655 successfully. Tested with two routers, two servers and two
658 * Tested channel message sending in router environment successfully.
660 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Added silc_server_save_channel_key into server.[ch] to save the
663 received channel key in Channel Key payload processing. It is
664 also used in JOIN command reply handling.
666 Equivalent function silc_client_save_channel_key added into
667 client.[ch] into client library.
669 * Changed JOIN command reply to send information whether the channel
670 was created or not (is existing already) and the channel key
671 payload. Changed protocol specs accordingly.
673 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
674 the request was sent by ID and not by nickname. Crashed on
677 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
680 now correctly save the received data.
682 * silc_server_free_sock_user_data now notifies routers in the
683 network about entities leaving the network.
685 At the same time implemented functions silc_server_remove_id
686 and silc_server_send_remove_id to receive and send REMOVE_ID
687 packets. The packet is used to notify routers in the network
688 about leaving entities. The ID removed will become invalid in
691 * Added function silc_idlist_del_server into server. Removes and
692 free's server entry from ID list.
694 * silc_server_private_message function now checks, if we are router,
695 that the destination ID really is valid ID, naturally.
697 * In router when NEW_ID packet is received (for new client) the
698 hash of the Client ID is saved in the ID Cache but the
699 client->nickname is set to NULL, instead of putting the hash
702 IDENTIFY command now also checks that client->nickname must be
703 valid. If it is not if will request the data from the server who
704 owns the client. Added new function
705 silc_server_command_identify_check.
707 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
708 to set the command to already allocated Command Payload.
710 * Tested private message sending in router environment with two
711 routers, two servers and two clients. Fixed minor bugs and now
714 * Fixed segfault from client's NAMES command. Used to crash if
717 * Forwarded packets must not be routed even if it is not destined
718 to the receiver. Changed server code comply with this.
720 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Added `require_reverse_mapping' boolean value to ServerParams
723 structure. If TRUE (not default) the server will require that
724 the connecting host has fully qualified domain name.
726 If the reverse mapping is not required and hostname could not be
727 found the IP address is used as hostname.
729 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Implemented version string checking to both client and server.
732 The check is incomplete currently due to the abnormal version
733 strings used in development version of SILC.
735 * Changed all command functions in server to use the new
738 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
740 * Changed char *data to unsigned char *data in ID Cache system to
741 support binary data as ID Cache data. Changed code to support
742 binary data in lib/silccore/idcache.c.
744 * Renamed silc_server_packet_relay_command_reply to
745 silc_server_command_reply as it is normal packet receiving
746 function. Rewrote the function to accept command replys for
747 servers and not only for clients.
749 * Mark remote router always as registered server if we are connecting
750 to it. Otherwise, commands sent by the router to us are ignored.
752 * All ID List find routines now returns the ID Cache Entry pointer
753 as well if requested.
755 * WHOIS command works now in router environment, tested with two
756 routers, two servers and two clients.
758 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
759 in router environment (as it is almost equivalent to WHOIS) but
760 hasn't been tested thoroughly. Added new functions:
762 silc_server_command_identify_parse
763 silc_server_command_identify_send_reply
764 silc_server_command_identify_from_client
765 silc_server_command_identify_from_server
767 * Disabled route cache adding because adding two different ID's with
768 same IP replaces the old cache entry thus giving wrong route.
769 The entry->router->connection is always the fastest route anyway
770 so route cache may not be needed. Of course, new routes maybe
771 established after receiving the ID when the entry->router->connection
772 might not be anymore the most optimal.
774 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Add route cache for received ID for fast routing.
778 * Added silc_server_packet_route to route received packet on router
779 that is not destined to us.
781 * Renamed silc_server_get_route to silc_server_route_get.
783 * Added id_string and id_string_len fields into SilcServer to
784 include encoded ServerID for fast comparing without excess
785 encoding of the ID's.
787 * Cleaned up WHOIS command on server side. Added following static
790 silc_server_command_whois_parse
791 silc_server_command_whois_check
792 silc_server_command_whois_send_reply
793 silc_server_command_whois_from_client
794 silc_server_command_whois_from_server
796 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
797 arguments in command replies. All command functions should be
798 updated to use this macro.
800 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Minor typo fixes on command reply handling on server.
804 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Added silc_server_command_add_to_channel internal routine to add
807 the client to the channel after router has created the channel and
808 sent command reply to the server.
810 * Added generic silc_server_send_command to send any command from
813 * Use static buffer with ID rendering instead of duplicating data.
815 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Fixed a channel user mode bug when joining to a channel server gave
818 everybody channel founder rights, oops.
820 * We mark ourselves as the router of the incoming server connection
821 if we are router ourselves. This way we can check in some packet
822 sending functions whether it is locally connected server. For
823 incoming router connections we put NULL.
825 * For router sending packets locally means now always sending the
826 packet cell wide; to local clients and local servers. For normal
827 server sending packet locally means sending it to only local
830 * Fixed the JOIN command to really work in router environment. If the
831 channel is created it is always created by the router. Router is
832 also responsible of making the initial joining to the channel,
833 sending JOIN notify to the sending server and distributing
834 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
835 does not exist server doesn't do anything else but forward the
836 command to the router which performs everything.
838 * Added silc_server_send_channel_key function to send the Channel Key
841 * Added silc_server_create_channel_key to create new channel key. The
842 channel key is now re-generated everytime someone joins or leaves
843 a channel, as protocol dictates. Note: channel->key_len is the
846 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Splitted server.[ch] finally. Created now packet_send.[ch] and
849 packet_receive.[ch] to separate packet sending and receiving
850 routines. The server.[ch] now includes everything else including
851 actual packet processing (writing and reading data) and other
854 Renamed silc_server_private_message_send_internal to
855 silc_server_send_private_message. The routine is still though
856 used only to relay private messages as server does not send
857 private messages itself.
859 Renamed silc_server_new_channel to silc_server_create_new_channel
860 and added new function sicl_server_new_channel that handles the
861 incoming New Channel packet. Added also new sending function
862 silc_server_send_new_channel to send New Channel Payload.
864 * Added new function silc_server_notify to process incoming notify
865 packet to the server/router. Server may then relay the notify
866 to clients if needed.
868 * Added new function silc_server_new_channel_user to process incoming
869 New Channel User packet. Router will redistribute the packet and
870 send JOIN notify to its local clients and locally connected servers
871 if needed. Normal server will send JOIN notify to its local client
872 on same channel when received this packet. Added also corresponding
873 sending function silc_server_send_new_channel_user to sent the
876 * Added boolean route argument to send_notif_to_channel and
877 packet_send_to_channel functions to attempt to route the packet
878 if it is TRUE and send only locally if it is FALSE.
880 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * silc_server_replace_id now broadcasts the received replace ID
883 packet if it is not broadcast packet already. The router must
884 broadcast to inform other routers about changed ID.
886 * Added backpointer to server's router into SilcServer context in
887 silcd/server_internal.h.
889 * Fixed silc_server_packet_broadcast to send correct broadcast
892 * The channel key is now distributed to the local client as soon
893 as it is received from the router (in router environment) so that
894 no other packet may be sent for the channel until client has
897 * silc_server_remove_channel_user now broadcasts the received
898 Remove Channel User packet if it is not broadcast packet already.
899 The router must broadcast to inform other routers about removed
902 * Added users field into SilcPacketContext that is a reference count
903 of the context. One can increase the reference count by calling
904 silc_packet_context_dup which is now changed to just increase the
905 reference count instead of duplicating the data. The reference
906 count is decresed by calling silc_packet_context_free that will
907 free the data after the reference count hits zero.
909 For now on the packet context and everything allocated into it
910 (including the raw packet from network) must be freed by calling
911 the new silc_packet_context_free function. Added also new function
912 silc_packet_context_alloc that must be used now to allocate the
913 context. This also means that if a routine is asynchronous from
914 silc_[client/server]_packet_parse_type the packet context must
915 be duplicated by calling silc_packet_context_dup. Otherwise it
916 gets free'd after silc_[client/server]_packet_parse_type returns.
917 Also, one must remember that if packet is duplicated then its
918 reference count must be decresed by calling the free function as
919 many times as it was duplicated.
921 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
922 from both client and server.
924 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Made joining to a channel working in router environment.
928 * Cleaned up JOIN command on server side and create function
929 silc_server_command_join_channel internal routine to make the
932 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Changed silc_command_pending list to SilcDList. Also, added
935 `ident' field to SilcServerCommandPending structure to identify
936 the reply and to call correct callback.
938 Added silc_server_command_pending_check function to replace the
939 corresnponding macro. The silc_command_pending list is not
942 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
943 to set identifier to previously allocated Command Payload. It
944 is used to set identifier for command when resending Command
947 * Added silc_command_payload_encode_payload to encode Command
948 Payload buffer from SilcCommandPayload structure.
950 * Added silc_argument_payload_encode_payload to encode Argument
951 payload buffer from SilcArgumentPayload structure.
953 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Changed WHOIS command to support router connection on server side.
956 The whois request is always sent to router unless the server is
957 standalone server. After server has received the reply from the
958 router will it send the reply to the client.
960 * Added silc_server_packet_broadcast into silcd/server.[ch] to
961 broadcast received broadcast packet. The function is used only
962 by router. The broadcast packet is always sent to the router's
965 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
966 render given ID to printable string, for log files for example.
968 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Made basic router to router connections working. At least they
971 can now connect to each other but nothing really works the way
972 they are supposed - yet.
974 * Added new initiator token to RouterConnection configuration
975 file in silcd/serverconfig.[ch]. It is used to tell whether we
976 are the initiator to the remote router or whether we'll expect
977 the other end to connect.
979 * Moved registering of listener task to silc_server_init, hence
980 the server starts listenning as soon as it is run, even if it
981 does not have connections to other routers. Let's see how well
984 * Changed default connection retry timeouts for more suitable in
987 * Removed cipher and such arguments from silc_idlist_add_client
988 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
989 Added new function silc_idlist_add_data to add the keys and stuff
992 * Added SilcIDListData structure and added it to SilcClientEntry
993 and SilcServerEntry as their first field in the structure. This
994 way we can explicitly cast the ID entries to the SilcIDListData
995 structure and get common data for the entries. In past, we had
996 to first check what type of connection it is and then cast it to
997 correct ID entry type. Now, we can directly cast the opaque
998 pointer to the SilcIDListData (no matter what ID entry it actually
999 is) and get the data needed.
1001 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1004 in some circumstances even if threre were timeout tasks, though not
1005 IO tasks, but tasks anyway. Now fixed.
1007 * Defined SilcServerConnection structure to hold connection specific
1008 stuff about directly connected servers and routers. The definition
1009 is currently in silcd/server_internal.h. I thought about having
1010 a bit more important role fro this struct but for now it is used
1011 only when connecting to other server (or router actually).
1013 * Added connecting retry support in server when connecting to
1014 router(s). The retry feature implement exponential backoff
1015 algorithm. Also, added SilcServerParams structure to hold default
1016 parameters for server. For now, it include these retry settings
1017 and are hard coded. After server is moded to be as Silc Server
1018 Library this structure will be more important.
1020 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Changed client librarys channel->clients table to SilcList and
1023 changed code accordingly.
1025 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Changed client's channel table to SilcList and changed code
1028 accordingly. Also changed SilcChannelClientEntry to include back-
1029 pointer to the channel so that client entry can use that structure
1030 as list as well and we have fast cross-reference to the channel.
1031 This change dramatically decreased the complexity of channel
1032 handling with client entry and vice versa (removed one extra
1033 loop when searching for channel entry from many functions).
1035 * Changed server->sim from table to SilcDList and changed code
1038 * NAMES command can now be used from user interface. It will show
1039 the user list on the channel, neatly.
1041 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1042 Code now saves realname of the user if it becomes available.
1044 * Renamed configure.in to configure.in.pre and made ./prepare
1045 script to automatically add correct version string to
1046 configure.in which it creates from configure.in.pre.
1048 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * NAMES command reply now shows users mode with the nickname when
1053 * Moved silc_client_ch[u]mode[_char] functions from
1054 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1055 place sucks, they are utility functions and should be in some
1058 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1060 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1063 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Added TRQ (efficient deque and list library) into lib/trq. This is
1068 a very good list library that is currently used in the SILC. Defined
1069 SilcList API over the library because I didn't like the API very
1070 much. See lib/trq/silclist.h for the API and examples of how to
1071 use the API. Fixed various places in the code to use the new
1072 SilcList API. The SilcList is meant for lists that has a structure
1073 already defined as a list. It is not suitable to add just some
1074 context to the list (in TRQ, the context is the list actually).
1076 So, I defined SilcDList that can be used for the purpose where
1077 predefined list structure does not exit. This can be used as
1078 such list. Now some context just can be added to the SilcDList.
1079 Currently this list is not used in the SILC just yet, though there
1080 are a lot places where this can replace dynamically allocated
1081 tables and I will fix these places, later, to use SilcDList.
1082 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1083 and use TRQ internally).
1085 Also fixed some annoying warning messages that the original TRQ
1086 code generated. Also minor changes to TRQ's Makefile.in.
1088 * Added support for querying by Client ID to both WHOIS and
1089 IDENTIFY commands into server, as required by the protocol.
1091 * Removed method function pointers from SilcBuffer structure. They
1092 weren't used to anything and just increased the context size for
1093 no good reason. This change also made silc_buffer_alloc and
1094 silc_buffer_free functions inline functions.
1096 * Disabled command flooding detection support until it's fixed so
1097 that it accepts commands in but does not execute them more than once
1100 * Added silc_net_localhost(), to return local hostname, into
1101 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1102 that must be initialized before calling silc_client_init.
1104 * Added new function: silc_server_send_notify_on_channels to send
1105 notify messages to all channels client has joined. It is assured
1106 that the message is sent only once per client.
1108 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1109 lib/silcutil/silcutil.[ch] as silc_format function. The new
1110 function is generic and is used by server as well, not only by
1111 the logging routines.
1113 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1114 the provided version string was not acceptable. Added new function:
1115 silc_ske_check_version into lib/silcske/silcske.h. The function
1116 must be implemented by the application (client or server) and it
1117 does not reside in the SKE library. The function checks the version
1118 string remote end sent.
1120 * Added back pointers (to opaque context and to SilcSocketConnection)
1121 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1123 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1124 duplicate packet context structure.
1126 * Changed `notify' client operation to send same arguments as client
1127 receives from server except for ID's. ID's are mapped to correct
1128 ID entry and that is returned. Also, if channel entry is not sent
1129 by server but the notify is for channel the channel entry is sent
1130 to application (otherwise application doesn't know that it is for
1131 channel (library gets it from packet's Destination ID)).
1133 * Added silc_client_remove_from_channels into client library to
1134 remove a client from all channels it has joined to. Used when
1135 received SIGNOFF notify from server. Added also new function
1136 silc_client_replace_from_channels to replace old ID entry with
1137 new ID entry on all channels. Used when received NICK_CHANGE
1140 * Fixed ID Cache list handling in silc_idlist_get_client in
1141 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1142 to get (or query) client by ID.
1144 * Updated TODO list.
1146 * Added connection authentication status message defined by the
1147 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1148 support for these into the code in client and server side.
1150 * Added generic function silc_client_send_command to send any command
1151 with variable argument list. Application should use this function
1152 to send commands if the command functions provided by the library
1153 does not suite for the application's user interface needs.
1155 * Added new `failure' client operation. Application is notified about
1156 received failure packet if client is executing a protocol. In this
1157 case the protocol's execution has failed.
1159 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1160 is required by the protocol.
1162 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1163 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1166 * Added status flag to SilcSKE object to indicate realtime status
1167 of the SKE protocol.
1169 * Application receives now exactly same command reply arguments as
1170 the library receives from server. However, if ID is received the
1171 corresponding ID entry is returned to the application (eg. Client
1172 ID is mapped to correct SilcClientEntry entry and that is returned).
1173 Changed command_reply client operation due to this change.
1175 * Changed all ID's in commands and in command replys as ID Payloads.
1176 Change affected both client and server side codes.
1178 All ID's sent in SILC network (with execption of ID's in SILC
1179 Packet header) are sent in ID Payload to support variable length
1182 * Server now notifies nick changes and notifies all clients on
1183 the channels about the new nickname (about the new Client ID,
1186 * Implemented CMODE command to change channel modes. Supports all
1187 channel modes defined by the protocol specs except ban and invite
1188 lists. (Also, private channel key mode is supported but support for
1189 setting private channel key in client is missing, thus, this mode
1190 has no effect on client side (except that server requires that the
1191 client uses private channel key and normal channel traffic does not
1194 Also, invite mode works per se, but INVITE command does not work
1195 yet correctly, so you can set channel as invite only channel but
1196 inviting clients to the channel does not work (it is yet to be
1197 thought what's the best way to do it).
1199 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1200 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1201 Implemented CUMODE command to change user's mode on the channel.
1202 Supports all modes defined by the protocol specs.
1204 * Added NAMES command reply to return users modes on the channel.
1206 * Removed unnecessary and slow ciphers from lib/silccrypt.
1208 * Set SO_KEEPALIVE option to connection sockets by default.
1210 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1212 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1213 redefined the Notify Payload into protocol specs.
1215 * Added silc_id_payload_parse_id to get ID directly from raw
1218 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1221 accept searching by Client ID as well.
1223 * Added support for LEAVE and SIGNOFF notify types in client library.
1225 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1226 to parse ID Payload from raw data.
1228 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added flags parameter into silc_ske_assemble_security_properties
1231 function in lib/silcske/silcske.[ch].
1233 * Changed notify client operation to fit better for notify messages
1234 sent by server. The notify payload received from server is now
1235 passed to the application (after parsing it to SilcNotifyPayload).
1236 It is application's responsibility to retrieve the arguments
1237 from the payload and show the message the way it wants. The message
1238 sent by server is implementation specific.
1240 * Changed public keys to comply with the protocol specification.
1241 Old public keys are not supported anymore and are not compatible.
1243 * Removed nickname from Channel Payload as the latest draft removed
1244 it. The client must resolve the nickname from the NAMES command
1245 reply received when it joined the channel.
1247 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1249 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1251 * Fixed some errors in protocol specification drafts.
1253 * Created lib/silccore/silcnotify.c to implement Notify Payload
1254 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1255 generic payloads described by protocol specifications. The file
1256 includes implementations for ID Payload and Argument Payload.
1258 * Changed Command Payload implementation to use the new Argument
1259 Payload. Changed command_xxxx_payload to command_payload_xxxx
1260 to comply with SILC coding conventions.
1262 * Added suppport for Argument Payload handling in Notify Payload
1263 implementation as protocol requires it. Added the new support
1264 into server and client lib as well.
1266 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Added support for multiple nicknames on same channel. [n] is
1269 added locally to the nickname if there are more than one same
1270 nicknames on the channel.
1272 * Server now sends all nicknames that matched WHOIS request.
1273 Client also shows the list received from server.
1275 * Added TOPIC command to client side. User can now set and show
1276 current topic on channel.
1278 * Added MOTD command to client and server. Also, server sends the
1279 motd when client connects to the server.
1281 * Changed version strings to comply ISO 8601.
1283 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Fixed protocol error handling in client library. It should now
1286 cope even if the SKE fails for some reason.
1288 * Made new protocol specification drafts for submitting to IETF.
1290 * Implemented TOPIC command to server in silcd/command.c.
1292 * Added two new notify types into lib/silccore/silcnotify.h:
1293 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1294 notify nickname change and topic setting/change on a channel.
1296 * API change of command_reply operation in client library. The
1297 application gets now the status type received from server as well.
1299 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1303 * Cras fixed and optimized the packet handling even further and
1304 it should work now. Minor change to the prototype of function
1305 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1307 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added new function into lib/silcutil/silcschedule.[ch]:
1310 silc_schedule_with_fd to select() a specified fd. The function
1311 returns after timeout expires or data arrives or goes. The
1312 function is used by packet routines to wait that all data is
1313 received from network.
1315 * Fixed data reading from network in lib/silccore/silcpacket.c.
1316 The code now assures that all data is read from the fd and then
1317 continues packet processing. This was a bug fix since the code
1318 used to drop some data in some circumstances.
1320 * Added new function into lib/silcclient/client.[ch]:
1321 silc_client_start_key_exchange to start key exchange after
1322 connection has been established to server. The code internally
1323 now uses this funtion but its main purpose was to provide it
1324 for applications that perform their own connecting. After
1325 application has created a connection it merely calls this
1326 function to start the key exchange between client and server.
1327 The library takes care of everything else after that.
1329 Updated also lib/silcclient/README to explain the usage of
1332 * Do not send to application information that connection has
1333 been established. Application gets notified it by connect
1336 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1338 * Applied cras's patch to add silc_schedule_one function. The
1339 function runs scheduler once and returns.
1341 * Fixed the scheduler after cras messed it up. The timeout
1342 handling works now as it's supposed to work.
1344 * Added into lib/silccore/ silcnotify.h to include notify
1345 message types support. Changed silc_server_send_notify*
1346 functions, in server.[ch], to support those new notify types.
1347 Added the support for the notify types into client library,
1348 as well. Added new notify client operation into ops.h in
1351 * Changed silc_server_packet_send_to_channel to send normal
1352 packets instead of just channel message packets. The function
1353 is now used to send the notify packets to channels. It is not
1354 used to send channel message packets anymore, as server never
1357 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1358 va_arg()s as it seems to require it nowadays. I guess, if SILC
1359 is compiled with older va_arg() the new code should work anyway.
1361 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Splitted core library. Core library (lib/silccore) includes
1364 now only SILC protocol specific core (and common) components.
1365 Created new utility library (lib/silcutil) that includes more
1366 generic purpose stuff. The stuff for util library was taken
1367 from the old core library. This was minor and easy split.
1369 * Created SILC Client Library (lib/silcclient) that includes
1370 implementation of the SILC client without user interface. This
1371 was major move from silc/ directory. The code has been changed
1372 so that it is transparent towards the user interface. The
1373 silc/ directory includes now the same user interface as before
1374 and it uses the new client library. Read lib/silcclient/README.
1375 Basicly, the client library performs everything else related
1376 to SILC except user interface handling. Also, configuration
1377 files are considered to be part of user interface and library
1378 does not handle them.
1380 This change also changed a lot of structures, function naming etc.
1381 Most important change was that SilcClientWindow object was
1382 renamed to SilcClientConnection in the client library. Created
1383 also new file lib/silcclient/ops.h. Also added new files
1384 silc/local_command.[ch] and silc/client_ops.[ch].
1386 All these changes were made to make it easier for user interface
1387 designers to create what ever user interface for the SILC client
1390 It is also expected that the server will be moved to lib
1391 directory as well and SILC Server Library will be created;
1392 sometimes in the future.
1394 * Removed Local commands from lib/silccore/silccommand.h as
1395 they are application specific and new client library does not
1396 handle any of those anymore.
1398 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1399 old client implementation in silc/.
1401 * Added support for callback functions in SILC_LOG_* macros.
1402 Application can now set its own callbacks that will be called
1403 instead of using the default functions that will always print
1404 the debug messages to stderr (or stdout). Also, debugging can
1405 now be disabled by setting silc_debug to FALSE and re-enabled by
1406 setting it to TRUE. Note, that logging will still work even
1407 if debugging is disabled.
1409 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1410 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1411 silc_log_reset_debug_callbacks.
1413 * To enable debugging in silc client one must give now -d
1414 option on command line.
1416 * Changed silc_schedule_init to automatically allocate task queues
1417 if they are not allocated before calling it.
1419 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Added GMP 3.1 into math library.
1423 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1426 a channel in SILC network. The packet is used by servers and
1427 routers to notify other routers that user has left a channel.
1428 This little feature was missing until now. Added the feature
1429 to protocol specification as well.
1431 Added functions: silc_server_send_remove_channel_user and
1432 silc_server_remove_channel_user into server.[ch].
1434 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1435 lib/silccore/silcpacket.h. However, they are not implemented
1438 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Fixed joining to a channel and sending channel messages
1441 between server and router. The channel message sending should
1442 now work inside a cell.
1444 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Fixed the private message sending between server and router.
1447 The private message sending should now work inside a cell.
1449 * Added silc_server_replace_id into server.[ch] to replace
1450 existing ID in the SILC network.
1452 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1453 and silc_idlist_replace_server_id into idlist.[ch] in server.
1455 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1457 * Fixed the server to server connections. Server can again now
1458 connect to router. Router to router connections probably does
1461 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Added dynamic protocol registering support. Now protocols can
1464 registered and unregistered on the fly. Patch by cras.
1466 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Added lib/contrib directory to hold routines that some platforms
1469 don't have but are needed by SILC.
1471 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1472 into lin/contrib to provide getopt() and getopt_long() for
1473 those who don't have it.
1475 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Added AWAY command to client. When away message is set and
1478 client receives a private message packet the client automatically
1479 replies to the sender with the away message.
1481 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1482 bug seemed to be the cause of recent problems when compiling
1485 * Added version detection support to SKE protocol specification
1486 and added the new changes to the SKE implementation as well.
1487 There were other minor changes in the SKE protocol as well.
1489 Many changes in lib/silcske/silcske.[ch] and in
1490 lib/silcske/payload.[ch].
1492 * Added ^U functionality, clear input line. Patch from cras.
1494 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Mainly small bugfixes on core library. Fixed some debugging
1497 logging and buffer overflow in silclog.c.
1499 * Updated config.sub and config.guess on the distribution tree.
1501 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Added command lagging support in server. Client may execute
1504 commands now only once in two seconds.
1506 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Optimized packet reception. MAC computation and checking is now
1509 also more optimized. A lot previously duplicated code is now
1510 used as generic by both client and server.
1512 * Fixed key pair generation in clientutil.c
1514 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1516 * Added into lib/silccore/silcbufutil.[ch] new function;
1517 silc_buffer_realloc.
1519 * Moved generic packet sending/encryption functions to
1520 lib/silccore/silcpacket.[ch] from client and server. Some
1521 rewriting of the functions.
1523 * Moved all generic packet reception/decryption functions to
1524 lib/silccore/silcpacket.[ch] from client and server. The
1525 packet processing is now much cleaner in both client and server.
1526 These were major changes in both client and server.
1528 * Created many common functions in server to do packet sending.
1529 Previously code were duplicated a lot, this has been removed
1532 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1534 * Rewrote major parts of the ID cache system. Don't know
1535 whether it is better now or not but at least the API is more
1538 * Major rewrite on ID cache stuff on client because of the ID
1539 cache API changes. Added idlist.c to client.
1541 * Also major rewrite on ID cache stuff on server as well.
1542 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1543 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1544 in hand, instead they are all put into the ID cache system now.
1545 All server_idlist_* routines uses ID cache now instead of
1546 traversing its own lists (those lists does not exist anymore).
1547 SilcIDList though still exists. Also, SilcXXXEntry's are
1550 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Finally made the SKE implementation compliant to the protocol
1553 specification. All mp integers are now binary encoded as
1554 opposed being HEX encoded.
1556 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1559 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1560 functions: silc_[encode/decode]_pem. Also added function
1561 silc_encode_pem_file to PEM encode with newlines ('\n') for
1564 * SILC public keys are now encoded either PEM or binary. Same
1565 option is for private keys as well. By default private keys
1566 are binary encoded and public keys PEM encoded. Silly HEX
1567 encoding were removed.
1569 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1570 function to create fingerprints.
1572 * Fixed a bug in SHA1; does not change the original data anymore.
1574 * Partly implemented INFO command on client and server side.
1575 Fixed CLEAR command. Changes to SERVER command; show current
1576 server(s) when giving command without arguments. Added
1577 VERSION command to client.
1579 * Added check to server that unregistered connections cannot
1580 execute commands (unless it is specificly allowed).
1582 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Fixed screen refresh.
1586 * Fixed channel joining bug from client. On some circumstances
1587 client tried to join to a channel it had already joined.
1589 * Added public key verification process into client's protocol.c.
1590 The client now verifies the public key from user and saves
1591 it into ~./silc/serverkeys/ directory.
1593 Added into: clientutil.[ch]: silc_client_verify_server_key.
1595 * Changed SKE protocol's silc_ske_initiator_finish function
1596 to accept callback function that verifies the received public
1597 key. Removed old silc_ske_verify_public_key function.
1599 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1602 silc_pkcs_private_key[_data]_set.
1604 * Made the password and public authentication more cleaner in
1605 server's protocol.c.
1607 * Removed historic and obsolete protocol `channel_auth' from
1608 both client and server.
1610 * Removed wrong way of sending command status messages from
1611 server to client in server's command.c. The old way violated
1612 protocol specification.
1614 Changes to silccore/silccommand.[ch]: removed
1615 silc_command_encode_status_payload -> not needed anymore,
1616 changed silc_command_encode_payload_va to accept extra
1617 argument on variable argument list. The argument type must
1618 now be provided to the function. Also, added new function:
1619 silc_command_encode_reply_payload_va which is same as
1620 normal command_encode_payload_va except command status type
1621 is provided as extra argument.
1623 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Added ~./silc directory handling. The directory includes the
1626 public and private keys for the client.
1628 Added silc_client_check_silc_dir, silc_client_create_identifier
1629 and silc_client_load_keys.
1631 * Implemented SILC protocol compliant public key. Added public
1632 and private key saving to and loading from files.
1634 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1635 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1636 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1637 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1638 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1640 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1641 silc_pkcs_load_[public/private]_key.
1643 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added silc_server_get_route (route.[ch]) to get connection
1646 data for the fastest route for given ID.
1648 * Implemented INVITE command on client and server. The command
1649 were re-defined in the SILC Protocol Specification and the
1650 implementation now complies with the specification.
1652 * Implemented PING command on client and server.
1654 * Implemented NAMES command on client and server. The server side
1655 supports currently only normal server not router server yet.
1656 Some changes to NAMES definition in SILC protocol specification.
1658 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Implemented LEAVE command on client and server.
1662 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1663 again. This change was made to the protocol as well. Server
1664 should not violate the protocol specification anymore.
1666 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1668 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1669 was tested. SOCKS4 was not but should work anyway.
