3 * Added CREDITS file. The CHANGES and CREDITS file will appear
4 in the distribution as well.
6 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
9 types in the server's silcd/packet_receive.c.
11 * Implemented CMODE and CUMODE to work in router environment.
13 * Fixed minor encoding and decoding buglet from the
14 lib/silccore/silcmode.c.
16 * Fixed buffer overflow from lib/silcclient/command.c in USERS
19 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
21 * Changed all SilcConfigServer* and silc_config_server* to
22 SilcServerConfig* and silc_server_config*, respectively.
25 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Associated the ID (client or server ID) to the Authentication
28 Payload to avoid any possibility of forging. Updated the
29 protocol specification and the code accordingly.
31 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * The RSA key length is now save to the RsaKey context in the
34 key generation process in lib/silccrypt/rsa.c. The key length
35 is now used to figure out the maximum size of the block allowed
36 to be encrypted/signed.
38 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
39 is equivalent to the silc_mp_mp2bin but does not allocate any
42 * Changed silc_mp_mp2bin API to take length argument. If it is
43 non-zero then the buffer is allocated that large. If zero, then
44 the size is approximated using silc_mp_sizeinbase, which however
47 * Created Global RNG API which is global RNG that application can
48 initialize. After initializing, any routine anywhere in the
49 code (including library) can use RNG without allocating a new
50 RNG object. This was done to allow this sort of use of the
51 RNG in code that has no chance to allocate RNG object. All
52 applications currently allocate this and many routines in the
53 library use this. Affected file lib/silccrypt/silcrng.[ch].
55 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
56 it to use the Global RNG API.
58 * Defined Authentication Payload into protocol specification that
59 is used during SILC session to authenticate entities. It is
60 used for example by client to authenticate itself to the server
61 to obtain server operator privileges.
63 Implemented this payload into the lib/silccore/silcauth.[ch].
64 Implemented also routines for public key based authentication
65 as the new protocol specification dictates.
67 Moved definitions of different authentication methods from
68 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
70 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
71 silc_pkcs_verify and silc_pkcs_sign_with_hash and
72 silc_pkcs_verify_with_hash functions into the file
73 lib/silccrypt/silcpkcs.[ch].
75 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
77 * The client entry's userinfo pointer must be always valid.
78 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
79 will fail since it requires the userinfo. Now, the userinfo
80 is allocated as "" if actual userinfo does not exist. Actually,
81 it must exist and it is totally Ok to drop client connections
82 that does not announce the userinfo. However, we will make
83 this workaround for now.
85 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
86 to return the remote port by socket.
88 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
91 SILC_SERVER_PENDING_EXEC and added an new macro
92 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
93 data or when error occurs while processing the pending command.
95 Added new argument `destructor' into silc_server_command_pending
96 and to the SilcServerCommandPending object. This destructor is
97 now called after calling the pending callback or if error occurs
98 immediately. If error occurs the actual pending callback won't
99 be called at all - only the destructor. The destructor may be
100 NULL if destructor is not needed.
102 All this applies for client library code as well. Similar
103 changes were made there as well for the pending commands.
105 In the client, the application must now allocate the
106 SilcClientCommandContext with the silc_client_command_alloc
109 * Added reference counter to the SilcServerCommandContext. Added
110 function silc_server_command_alloc and silc_server_command_dup
113 Same type of functions added to the client library for the same
116 * Removed the cmd_ident from IDListData away since it is now
117 global for all connections. It is the command identifier used
118 in command sending and with pending commands. The affected file
121 * Added reference counter to the SilcSocketConnection objecet to
122 indicate the usage count of the object. The object won't be
123 freed untill the reference counter hits zero. Currently only
124 server uses this, and client ignores it. The client must be
125 set to use this too later. The affected files are
126 lib/silccore/silcsockconn.[ch]. Added also the function
127 silc_socket_dup to increase the reference counter.
129 This was mainly added because it is possible that the socket
130 is removed underneath of pending command or other async
131 operation. Now it won't be free'd and proper DISCONNECTING
132 flags, etc. can be set to avoid sending data to connection that
133 is not valid anymore.
135 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
136 the connection. After that it sets SILC_SET_DISCONNECTED.
137 It is, however, possible that the socket data is not still freed.
138 The silc_server_packet_process now checks that data is not
139 read or written to connection that is DISCONNECTED. The socket
140 get's freed when the reference counter hits zero.
142 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Changed the client operation API: channel_message operation's
145 `sender' is now the client entry of the sender, not the nickname
146 and the `channel' is the channel entry, not the channel name.
148 In the private_message operation the `sender' is now also the
149 client entry of the sender not the nickname.
151 Affected file is lib/silcclient/ops.h and all applications
152 using the client operations.
154 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Moved the calling of ops->connect() from connect_to_server_final
157 into receive_new_id functin since that is the point when the
158 client is actually allowed to send traffic to network. The
159 affected file is lib/silcclient/client.c.
161 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
163 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
164 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
165 (if needs broadcasting) instead of broadcasting the packets one
166 by one which would make a burst in the network traffic.
168 * Added `broadcast' argument to the functions in silcd/server.[ch]
169 silc_server_create_new_channel[_with_id] to indicate whether
170 to send New Channel packet to primary router.
172 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Added new function into the silcd/server.[ch] files:
175 silc_server_create_new_channel_with_id to create new channel with
176 already existing Channel ID.
178 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
179 lib/silccore/silcpacket.h. This packet is used t send list of
180 Set Mode payloads inside one packet. Server uses this to set
181 the modes for the channels and clients on those channels, that it
182 announced to the router when it connected to it. The protocol
183 specification has been updated accordingly.
185 * The silc_server_new_channel did not handle the packet coming
186 from normal server as it normally does not send that. However,
187 when it announces its channels it does send it. Implemented
188 the support for that.
190 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
191 into the file lib/silccore/id.h.
193 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Fixed memory leaks in the functions silc_idlist_del_client,
196 silc_idlist_del_channel and silc_idlist_del_server in the file
197 silcd/idlist.c. All of those leaked like a sieve.
199 * Fixed some small memory leaks in the client's function
200 silc_client_notify_by_server.
202 * Added functions into silcd/server.c: silc_server_announce_clients,
203 silc_server_announce_channels and silc_server_announce_server.
204 These functions are used by normal and router server to announce
205 to its primary router about clients, channels and servers (when
206 router) that we own. This is done after we've connected to the
209 These functions effectively implements the following packet types:
210 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
211 and SILC_PACKET_NEW_ID_LIST.
213 * Added new functions into the silcd/packet_receive.[ch]:
214 silc_server_new_id_list, silc_server_new_channel_list and
215 silc_server_new_channel_user_list to handle the incoming
216 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
218 * Added support of changing Channel ID in the function
219 silc_server_replace_id. If the server that announces a channel
220 to the router already exists in the router (with same name but
221 with different Channel ID), router is responsible to send
222 Replace ID packet to the server and force the server to change
223 the Channel ID to the one router has.
225 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
226 client that the Channel ID has been changed by the router. The
227 normal server sends this to the client. Client must start using
228 the new Channel ID as the channel's ID.
230 Implemented handling of this new type into lib/silcclient/client.c
231 into the function silc_client_notify_by_server.
233 * Added new function silc_idlist_replace_channel_id into the files
234 silcd/idlist.[ch] to replace the Channel ID.
236 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Call silc_server_command_identify_check always when processing
239 the IDENTIFY command in silcd/command.c
241 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
244 send keepalive packets. The packet can be sent by clients,
247 Added function silc_socket_set_heartbeat into the file
248 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
249 If not set, the heartbeat is not performed. The actual
250 heartbeat is implemented in the low level socket connection
251 library. However, application is responsible of actually
254 Added silc_server_send_heartbeat to send the actual heartbeat
255 packet into silcd/packet_send.[ch]. Server now performs
256 keepalive with all connections.
258 * Added silc_task_get_first function into lib/silcutil/silctask.c
259 to return the timeout task with shortest timeout. There was a bug
260 in task unregistration that caused problems. TODO has been
261 updated to include that task system must be rewritten.
263 * The client library will now resolve the client information when
264 receiving JOIN notify from server for client that we know but
265 have incomplete information.
267 * Rewrote parts of silc_server_remove_from_channels and
268 silc_server_remove_from_one_channel as they did not remove the
269 channel in some circumstances even though they should've.
271 * Encryption problem encountered in server:
273 The LEAVE command used to send the Channel Key packet to the
274 router immediately after generating it. However, the code
275 had earlier sent Remove Channel user packet but not immediately,
276 ie. it was put to queue. The order of packets in the router
277 was that Channel Key packet was first and Remove Channel User
278 packet was second, even though they were encrypted in the
279 reverse order. For this reason, MAC check failed. Now, this
280 is fixed by not sending the Channel Key packet immediately but
281 putting it to queue. However, this is more fundamental problem:
282 packets that are in queue should actually not be encrypted
283 because packets that are sent immediately gets encrypted
284 actually with wrong IV (and thus MAC check fails). So, packets
285 that are in queue should be encrypted when they are sent to
286 the wire and not when they put to the queue.
288 However, the problem is that the current system has not been
289 designed to work that way. Instead, the packet is encrypted
290 as soon as possible and left to the queue. The queue is then
291 just purged into wire. There won't be any fixes for this
292 any time soon. So, the current semantic for packet sending
295 o If you send packet to remote host and do not force the send
296 (the packet will be in queue) then all subsequent packets to the
297 same remote host must also be put to the queue. Only after the
298 queue has been purged is it safe again to force the packet
301 o If you send all packets immediately then it safe to send
302 any of subsequent packets through the queue, however, after
303 the first packet is put to queue then any subsequent packets
304 must also be put to the queue.
306 Follow these rules and everything works fine.
308 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Added new function silc_server_remove_clients_by_server to
311 remove all client entries from ID list when the server connection
312 is lost. In this case it is also important to invalidate all
313 client entires as they hold the invalid server entry. This
314 fixes fatal bug when server has lost connection and will reconnect
317 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Made some sanity checks to silc_server_daemonise like to check
320 whether the requested user and group actually exists.
322 * Added sanity check to SKE's silc_ske_responder_finish to check
323 that the public and private key actually is valid.
325 * Invalidate the client's nickname when receiving Replace ID
326 packet and the Client ID is being replaced. This means that the
327 server will query the nickname if someone needs it (client)
330 * Sort the ID Cache in client library when the ID Cache data
331 has changed (needs sorting).
333 * Do not allow for SILC client to create several connections to
334 several servers. The client does not support windows right now
335 and generating multiple connections causes weird behaviour.
337 Irssi-silc client does support windows and can handle several
338 connections without problems, see: www.irssi.org and SILC plugin.
340 * Fixed some places where client was added to the IDList. The
341 rule of thumb is following (in order to get everything right):
342 If the client is directly connected local client then the
343 `connection' argument must be set and `router' argument must be
344 NULL to silc_idlist_add_client function. If the client is not
345 directly connected client then the `router' argument must
346 bet set and the `connection' argument must be NULL to the
347 silc_idlist_add_client function.
349 * The funtion silc_server_packet_send_local_channel actually did
350 not check whether the client was locally connected or not. It
351 does that now. Fixed a bug related to LEAVE command.
353 * Fixed Remove Channel User payload parsing bug in server's
354 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
356 * The server's silc_server_save_channel_key now checks also the
357 global ID list for the channel as it might not be in the local
358 list. Fixed a bug related to LEAVE command.
360 * Is this the end of the [<unknown>] buglet that has been lurking
361 around for a long time? A little for loop fix in server's
362 silc_server_command_whois_parse that is used by both IDENTIFY
363 and WHOIS command. At least, this was a clear bug and a cause
364 of one type of [<unknown>] buglet.
366 * WHOIS and IDENTIFY commands call the function
367 silc_server_command_[whois/identify]_check function even if
368 we are not router server.
370 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Added --with-gmp configuration option. If set the GMP
373 is always compiled in the SILC source tree. If not set then
374 it is checked whether the system has the GMP3 installed. If
375 it has then the GMP won't be compiled (the system's headers
376 and library is used), if it doesn't have it then the GMP is
377 compiled in the SILC source tree.
379 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Changed RSA private exponent generation to what PKCS #1
382 suggests. We try to find the smallest possible d by doing
383 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
384 not security fix but optimization.
386 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Added new config entry [Identity] to fork the server and run
389 it as specific user and group. A patch from Bostik.
391 * Imported Dotconf configuration library into lib/dotconf.
392 This will be used to create the SILC configuration files later.
393 It will appear in the distsribution after this commit.
395 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * A big code auditing weekend happening. Auditing code for
398 obvious mistakes, bugs and errors. Also, removing any code
401 Removed files for being obsolete:
403 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
404 inline in the file lib/silcutil/silcbuffer.h)
406 o lib/silcutil/silcbufutil.c (the header has inline versions)
408 Changed code to fix possible error conditions:
410 o The buffer formatting routines now check that the destination
411 buffer really has enough space to add the data. This applies for
412 both buffer formatting and unformatting
413 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
414 unformatting was changed to accomodate following rules:
415 XXX_*STRING_ALLOC will allocate space for the data into the pointer
416 sent to the function while XXX_*STRING will not allocate or copy
417 the data into the buffer. Instead it sets the pointer from the
418 buffer into the pointer sent as argument (XXX_*STRING used to
419 require that the pointer must be allocated already). This change
420 makes this whole thing a bit more consistent and more optimized
421 (note that the data returned in the unformatting with XXX_*STRING
422 must not be freed now). The routines return now -1 on error.
424 o Tried to find all code that use buffer_format and buffer_unformat
425 and added return value checking to prevent formatting and
426 especially unformatting errors and possible subsequent fatal
429 o Changed ske->x and ske->KEY to mallocated pointers in
430 lib/silcske/silcske.h. Fixed possible data and memory leak.
432 o Added return value checking to all *_parse* functions. Fixed
433 many memory leaks as well.
435 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
436 so that buffer overflows would not happen. All code now also
437 checks the return value as it can fail.
439 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added reconnection support to server if the normal server looses
442 its connection to the router (for example if router is rebooted).
443 The server performs normal reconnection strategy implemented
444 to the server. Affected file silcd/server.c.
446 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Added new packet type SILC_PACKET_SET_MODE that is used to
449 distribute the information about changed modes (for clients,
450 channels and clients channel modes) to all routers in the
451 network. Updated the protocol specification accordingly.
453 Added functions into silcd/packet_send.c and
454 silcd/packet_receive.c: silc_server_send_set_mode,
455 silc_server_set_mode.
457 Added new files silcmode.[ch] into lib/silccore that implements
458 the encoding and decoding of Set Mode Payload. Added new type
459 SilcSetModePayload. Moved the definitions of different modes
460 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
462 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Oops, a little mistake in server's connection authentication
465 protocol. The protocol is not ended with FAILURE but with
466 SUCCESS if the authentication is Ok. :) Affected file is
469 * Implemented NICK_CHANGE notify handling in server in the file
470 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
471 the local clients on the channel. After the changing nickname
472 in router environment snhould work and the [<unknown>] nickname
473 should appear no more.
475 The silc_server_replace_id function that receives the Replace ID
476 payload now sends the NICK_CHANGE notify type also in the file
477 silcd/packet_receive.c
479 * Changed WHOIS and IDENTIFY command to support the maximum amount
480 of arguments defined in protocol specs (3328 arguments). This
481 fixed a bug that caused problems when there were more than three
484 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Added extra parameter, command identifier, to the
487 silc_client_send_command so that explicit command identifier
490 Changed that ID list routines uses specific command identifier
491 when sending WHOIS/IDENTIFY requests to the server so that they
492 can be identified when the reply comes back.
494 Affected files lib/silcclient/command.[ch],
495 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
497 * Added `sender' argument to silc_server_packet_send_to_channel
498 to indicaet the sender who originally sent the packet to us
499 that we are now re-sending. Ignored if NULL. Affected file
500 silcd/packet_send.[ch].
502 * Added some server statistics support in silcd/server_internal.h
503 SilcServerStatistics structure and around the server code. Also
504 send some nice statistics information when client is connecting
507 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Fixed channel ID decoding in server's JOIN command reply in
510 silcd/command_reply.c
512 * Fixed braodcasting of replace ID payload to not to send it if
513 we are standalone server in silcd/packet_receive.c.
515 * Fixed all channel message sending routines to not to send
516 packets to clients that has router set, since they are routed
517 separately in the same function earlier. Affects file
518 silcd/packet_send.c and all channel packet sending functions.
520 * In USERS reply, res_argv[i] are not allocated, the table
521 is allocated. Thus changed that free the table, not its
524 * In server's whois_check and identify_check if the client is
525 locally connected do not send any WHOIS commands - they are not
528 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Fixed some minor bugs in client when sending WHOIS command. The
531 arguments was in wrong order.
533 * Removed statis function add_to_channel from server in
534 silcd/command.c that was previously used with the joining but
537 * Tested USERS command in router environment successfully with two
538 routers, two servers and two clients.
540 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Reorganized the USERS command and command reply in client library
543 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
544 When the command is given by user we register a pending command
545 callback that will reprocess the command after the reply has been
546 received from the server. When reprocessing the packet we then
547 display the information. Thus, the USERS information is displayed
548 now in the command callback instead of in the command reply
549 callback. The processing of the command is same as previously
550 when server has sent the command reply in the JOINing process.
552 * Added to USERS command in silcd/command_reply.c to join the client,
553 we didn't use to know about, to the channel after we've created
554 a client entry for it. Also, for clienet we did know already still
555 check whether it is on the channel or not and add it if not.
557 * Removed silc_server_command_join_notify as the function and its
560 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Changed the client's pending command handling to the same as the
563 server's pending command handling. It is also now possible to
564 execute command reply functions from other command reply
565 function as the function callbacks for commands and command
566 replies are one and same. The pending commands are not static
567 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
568 in client connection context. Thus, pending commands are server
569 connection specific as it is convenient.
571 Changed the function silc_client_command_pending and
572 silc_client_command_pending_del and added new function
573 silc_client_command_pending_check. Removed the
574 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
577 * Added cmd_ident, current command identifier, to the client
578 connection context in lib/silcclient/client.h to keep track on
579 command identifiers used in command sending. Client's command reply
580 function handling now supports the mandatory command identifiers.
582 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
583 funtions in client to fully support pending command callbacks.
585 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
586 as one of the arguments to the application in the command reply
589 * NOTE: The FORWARDED flag is depracated. It used to be depracated
590 before first releasing SILC but came back. Now it is removed again
591 and should come back nomore. The FORWARDED flag was used only
592 by the JOINing procedure by forwarding the command packet to router.
593 Now, the JOINing procedure has been changed to more generic (due
594 to various router environment issues) and FORWARDED is not needed
595 anymore for anything. The protocol specification is yet to be
598 Now, removed silc_server_packet_forward from server and the flag
599 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
601 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Renamed NAMES command to USERS command. The NAMES was named that
604 due to historical reasons. Now it is renamed. Also, rewrote
605 parts of the USERS command. The nickname list is not sent anymore
606 by the server. Only Client ID and mode lists are sent in the USERS
607 command. Changed this also to the protocol specification.
609 The client now resolves the names and stuff after it receives
610 the USERS list from the server when joining to the channel.
612 * WHOIS and IDENTIFY commands has been changed to support multiple
613 Client ID's per command. One can now search for multiple users
614 in the network by sending only one WHOIS or IDENTIFY command.
615 Changed the code and the protocol specifications.
617 * Removed silc_server_command_identify_parse and changed that IDENTIFY
618 uses silc_server_command_whois_parse to parse the request. */
620 * If normal server, do not parse the WHOIS and IDENTIFY requests
621 before sending it to the router. Saves some time.
623 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Fixed JOIN command on client library. Wrong number of arguments
626 used to crash the client.
628 * Added silc_server_channel_has_global function to check whether
629 channel has global users or not.
631 * Added silc_server_channel_has_local function to check whether channel
632 has locally connected clients on the channel.
634 * The silc_server_remove_from_one_channel now checks whether the
635 channel has global users or not after given client was removed from
636 the channel. It also checks whether the channel has local clients
637 on the channel anymore. If it does not have then the channel entry
638 is removed as it is not needed anymore.
640 * The silc_server_notify now checks on JOIN notify whether the joining
641 client is one of locally connected or global. If it is global then
642 the channel has now global users on the channel and that is marked
643 to the channel entry. Also, it now saves the global client to
644 global list who is joining and JOINs it to the channel. This is
645 for normal server, that is.
647 Changed silc_server_send_notify_on_channel,
648 silc_server_packet_relay_to_channel and
649 silc_server_packet_send_to_channel check if we are normal server
650 and client has router set (ie. global client) do not send the
651 message to that client, as it is already routed to our router.
653 * Implemented LEAVE notify type handling in silc_server_notify
656 * Tested LEAVE command in router environment successfully. Tested
657 with two routers, two servers and two clients.
661 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
663 * Implemented SIGNOFF notify type handling in silc_server_notify
666 * silc_server_remove_id now removes the client entry from all channels
667 it has joined and thusly sends SIGNOFF notify type.
669 * Rewrote the NAMES list generation in server by removing two excess
670 loops. The lists are created now inside one loop.
672 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * silc_server_remove_channel_user checks now also global list
675 for channel and client.
677 * silc_server_new_channel_user checks now both local and global
678 list for channel and client. Fixed a bug in client id decoding.
679 Used to decode wrong buffer.
681 * silc_server_channel_message checks now both local and global
682 list for channel entry.
684 * Tested channel joining (hence JOIN) in router environment
685 successfully. Tested with two routers, two servers and two
688 * Tested channel message sending in router environment successfully.
690 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Added silc_server_save_channel_key into server.[ch] to save the
693 received channel key in Channel Key payload processing. It is
694 also used in JOIN command reply handling.
696 Equivalent function silc_client_save_channel_key added into
697 client.[ch] into client library.
699 * Changed JOIN command reply to send information whether the channel
700 was created or not (is existing already) and the channel key
701 payload. Changed protocol specs accordingly.
703 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
704 the request was sent by ID and not by nickname. Crashed on
707 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
710 now correctly save the received data.
712 * silc_server_free_sock_user_data now notifies routers in the
713 network about entities leaving the network.
715 At the same time implemented functions silc_server_remove_id
716 and silc_server_send_remove_id to receive and send REMOVE_ID
717 packets. The packet is used to notify routers in the network
718 about leaving entities. The ID removed will become invalid in
721 * Added function silc_idlist_del_server into server. Removes and
722 free's server entry from ID list.
724 * silc_server_private_message function now checks, if we are router,
725 that the destination ID really is valid ID, naturally.
727 * In router when NEW_ID packet is received (for new client) the
728 hash of the Client ID is saved in the ID Cache but the
729 client->nickname is set to NULL, instead of putting the hash
732 IDENTIFY command now also checks that client->nickname must be
733 valid. If it is not if will request the data from the server who
734 owns the client. Added new function
735 silc_server_command_identify_check.
737 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
738 to set the command to already allocated Command Payload.
740 * Tested private message sending in router environment with two
741 routers, two servers and two clients. Fixed minor bugs and now
744 * Fixed segfault from client's NAMES command. Used to crash if
747 * Forwarded packets must not be routed even if it is not destined
748 to the receiver. Changed server code comply with this.
750 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Added `require_reverse_mapping' boolean value to ServerParams
753 structure. If TRUE (not default) the server will require that
754 the connecting host has fully qualified domain name.
756 If the reverse mapping is not required and hostname could not be
757 found the IP address is used as hostname.
759 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Implemented version string checking to both client and server.
762 The check is incomplete currently due to the abnormal version
763 strings used in development version of SILC.
765 * Changed all command functions in server to use the new
768 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Changed char *data to unsigned char *data in ID Cache system to
771 support binary data as ID Cache data. Changed code to support
772 binary data in lib/silccore/idcache.c.
774 * Renamed silc_server_packet_relay_command_reply to
775 silc_server_command_reply as it is normal packet receiving
776 function. Rewrote the function to accept command replys for
777 servers and not only for clients.
779 * Mark remote router always as registered server if we are connecting
780 to it. Otherwise, commands sent by the router to us are ignored.
782 * All ID List find routines now returns the ID Cache Entry pointer
783 as well if requested.
785 * WHOIS command works now in router environment, tested with two
786 routers, two servers and two clients.
788 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
789 in router environment (as it is almost equivalent to WHOIS) but
790 hasn't been tested thoroughly. Added new functions:
792 silc_server_command_identify_parse
793 silc_server_command_identify_send_reply
794 silc_server_command_identify_from_client
795 silc_server_command_identify_from_server
797 * Disabled route cache adding because adding two different ID's with
798 same IP replaces the old cache entry thus giving wrong route.
799 The entry->router->connection is always the fastest route anyway
800 so route cache may not be needed. Of course, new routes maybe
801 established after receiving the ID when the entry->router->connection
802 might not be anymore the most optimal.
804 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Add route cache for received ID for fast routing.
808 * Added silc_server_packet_route to route received packet on router
809 that is not destined to us.
811 * Renamed silc_server_get_route to silc_server_route_get.
813 * Added id_string and id_string_len fields into SilcServer to
814 include encoded ServerID for fast comparing without excess
815 encoding of the ID's.
817 * Cleaned up WHOIS command on server side. Added following static
820 silc_server_command_whois_parse
821 silc_server_command_whois_check
822 silc_server_command_whois_send_reply
823 silc_server_command_whois_from_client
824 silc_server_command_whois_from_server
826 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
827 arguments in command replies. All command functions should be
828 updated to use this macro.
830 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Minor typo fixes on command reply handling on server.
834 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added silc_server_command_add_to_channel internal routine to add
837 the client to the channel after router has created the channel and
838 sent command reply to the server.
840 * Added generic silc_server_send_command to send any command from
843 * Use static buffer with ID rendering instead of duplicating data.
845 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Fixed a channel user mode bug when joining to a channel server gave
848 everybody channel founder rights, oops.
850 * We mark ourselves as the router of the incoming server connection
851 if we are router ourselves. This way we can check in some packet
852 sending functions whether it is locally connected server. For
853 incoming router connections we put NULL.
855 * For router sending packets locally means now always sending the
856 packet cell wide; to local clients and local servers. For normal
857 server sending packet locally means sending it to only local
860 * Fixed the JOIN command to really work in router environment. If the
861 channel is created it is always created by the router. Router is
862 also responsible of making the initial joining to the channel,
863 sending JOIN notify to the sending server and distributing
864 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
865 does not exist server doesn't do anything else but forward the
866 command to the router which performs everything.
868 * Added silc_server_send_channel_key function to send the Channel Key
871 * Added silc_server_create_channel_key to create new channel key. The
872 channel key is now re-generated everytime someone joins or leaves
873 a channel, as protocol dictates. Note: channel->key_len is the
876 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Splitted server.[ch] finally. Created now packet_send.[ch] and
879 packet_receive.[ch] to separate packet sending and receiving
880 routines. The server.[ch] now includes everything else including
881 actual packet processing (writing and reading data) and other
884 Renamed silc_server_private_message_send_internal to
885 silc_server_send_private_message. The routine is still though
886 used only to relay private messages as server does not send
887 private messages itself.
889 Renamed silc_server_new_channel to silc_server_create_new_channel
890 and added new function sicl_server_new_channel that handles the
891 incoming New Channel packet. Added also new sending function
892 silc_server_send_new_channel to send New Channel Payload.
894 * Added new function silc_server_notify to process incoming notify
895 packet to the server/router. Server may then relay the notify
896 to clients if needed.
898 * Added new function silc_server_new_channel_user to process incoming
899 New Channel User packet. Router will redistribute the packet and
900 send JOIN notify to its local clients and locally connected servers
901 if needed. Normal server will send JOIN notify to its local client
902 on same channel when received this packet. Added also corresponding
903 sending function silc_server_send_new_channel_user to sent the
906 * Added boolean route argument to send_notif_to_channel and
907 packet_send_to_channel functions to attempt to route the packet
908 if it is TRUE and send only locally if it is FALSE.
910 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * silc_server_replace_id now broadcasts the received replace ID
913 packet if it is not broadcast packet already. The router must
914 broadcast to inform other routers about changed ID.
916 * Added backpointer to server's router into SilcServer context in
917 silcd/server_internal.h.
919 * Fixed silc_server_packet_broadcast to send correct broadcast
922 * The channel key is now distributed to the local client as soon
923 as it is received from the router (in router environment) so that
924 no other packet may be sent for the channel until client has
927 * silc_server_remove_channel_user now broadcasts the received
928 Remove Channel User packet if it is not broadcast packet already.
929 The router must broadcast to inform other routers about removed
932 * Added users field into SilcPacketContext that is a reference count
933 of the context. One can increase the reference count by calling
934 silc_packet_context_dup which is now changed to just increase the
935 reference count instead of duplicating the data. The reference
936 count is decresed by calling silc_packet_context_free that will
937 free the data after the reference count hits zero.
939 For now on the packet context and everything allocated into it
940 (including the raw packet from network) must be freed by calling
941 the new silc_packet_context_free function. Added also new function
942 silc_packet_context_alloc that must be used now to allocate the
943 context. This also means that if a routine is asynchronous from
944 silc_[client/server]_packet_parse_type the packet context must
945 be duplicated by calling silc_packet_context_dup. Otherwise it
946 gets free'd after silc_[client/server]_packet_parse_type returns.
947 Also, one must remember that if packet is duplicated then its
948 reference count must be decresed by calling the free function as
949 many times as it was duplicated.
951 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
952 from both client and server.
954 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Made joining to a channel working in router environment.
958 * Cleaned up JOIN command on server side and create function
959 silc_server_command_join_channel internal routine to make the
962 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Changed silc_command_pending list to SilcDList. Also, added
965 `ident' field to SilcServerCommandPending structure to identify
966 the reply and to call correct callback.
968 Added silc_server_command_pending_check function to replace the
969 corresnponding macro. The silc_command_pending list is not
972 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
973 to set identifier to previously allocated Command Payload. It
974 is used to set identifier for command when resending Command
977 * Added silc_command_payload_encode_payload to encode Command
978 Payload buffer from SilcCommandPayload structure.
980 * Added silc_argument_payload_encode_payload to encode Argument
981 payload buffer from SilcArgumentPayload structure.
983 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Changed WHOIS command to support router connection on server side.
986 The whois request is always sent to router unless the server is
987 standalone server. After server has received the reply from the
988 router will it send the reply to the client.
990 * Added silc_server_packet_broadcast into silcd/server.[ch] to
991 broadcast received broadcast packet. The function is used only
992 by router. The broadcast packet is always sent to the router's
995 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
996 render given ID to printable string, for log files for example.
998 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1000 * Made basic router to router connections working. At least they
1001 can now connect to each other but nothing really works the way
1002 they are supposed - yet.
1004 * Added new initiator token to RouterConnection configuration
1005 file in silcd/serverconfig.[ch]. It is used to tell whether we
1006 are the initiator to the remote router or whether we'll expect
1007 the other end to connect.
1009 * Moved registering of listener task to silc_server_init, hence
1010 the server starts listenning as soon as it is run, even if it
1011 does not have connections to other routers. Let's see how well
1014 * Changed default connection retry timeouts for more suitable in
1017 * Removed cipher and such arguments from silc_idlist_add_client
1018 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1019 Added new function silc_idlist_add_data to add the keys and stuff
1022 * Added SilcIDListData structure and added it to SilcClientEntry
1023 and SilcServerEntry as their first field in the structure. This
1024 way we can explicitly cast the ID entries to the SilcIDListData
1025 structure and get common data for the entries. In past, we had
1026 to first check what type of connection it is and then cast it to
1027 correct ID entry type. Now, we can directly cast the opaque
1028 pointer to the SilcIDListData (no matter what ID entry it actually
1029 is) and get the data needed.
1031 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1034 in some circumstances even if threre were timeout tasks, though not
1035 IO tasks, but tasks anyway. Now fixed.
1037 * Defined SilcServerConnection structure to hold connection specific
1038 stuff about directly connected servers and routers. The definition
1039 is currently in silcd/server_internal.h. I thought about having
1040 a bit more important role fro this struct but for now it is used
1041 only when connecting to other server (or router actually).
1043 * Added connecting retry support in server when connecting to
1044 router(s). The retry feature implement exponential backoff
1045 algorithm. Also, added SilcServerParams structure to hold default
1046 parameters for server. For now, it include these retry settings
1047 and are hard coded. After server is moded to be as Silc Server
1048 Library this structure will be more important.
1050 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Changed client librarys channel->clients table to SilcList and
1053 changed code accordingly.
1055 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Changed client's channel table to SilcList and changed code
1058 accordingly. Also changed SilcChannelClientEntry to include back-
1059 pointer to the channel so that client entry can use that structure
1060 as list as well and we have fast cross-reference to the channel.
1061 This change dramatically decreased the complexity of channel
1062 handling with client entry and vice versa (removed one extra
1063 loop when searching for channel entry from many functions).
1065 * Changed server->sim from table to SilcDList and changed code
1068 * NAMES command can now be used from user interface. It will show
1069 the user list on the channel, neatly.
1071 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1072 Code now saves realname of the user if it becomes available.
1074 * Renamed configure.in to configure.in.pre and made ./prepare
1075 script to automatically add correct version string to
1076 configure.in which it creates from configure.in.pre.
1078 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * NAMES command reply now shows users mode with the nickname when
1083 * Moved silc_client_ch[u]mode[_char] functions from
1084 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1085 place sucks, they are utility functions and should be in some
1088 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1090 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1093 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Added TRQ (efficient deque and list library) into lib/trq. This is
1098 a very good list library that is currently used in the SILC. Defined
1099 SilcList API over the library because I didn't like the API very
1100 much. See lib/trq/silclist.h for the API and examples of how to
1101 use the API. Fixed various places in the code to use the new
1102 SilcList API. The SilcList is meant for lists that has a structure
1103 already defined as a list. It is not suitable to add just some
1104 context to the list (in TRQ, the context is the list actually).
1106 So, I defined SilcDList that can be used for the purpose where
1107 predefined list structure does not exit. This can be used as
1108 such list. Now some context just can be added to the SilcDList.
1109 Currently this list is not used in the SILC just yet, though there
1110 are a lot places where this can replace dynamically allocated
1111 tables and I will fix these places, later, to use SilcDList.
1112 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1113 and use TRQ internally).
1115 Also fixed some annoying warning messages that the original TRQ
1116 code generated. Also minor changes to TRQ's Makefile.in.
1118 * Added support for querying by Client ID to both WHOIS and
1119 IDENTIFY commands into server, as required by the protocol.
1121 * Removed method function pointers from SilcBuffer structure. They
1122 weren't used to anything and just increased the context size for
1123 no good reason. This change also made silc_buffer_alloc and
1124 silc_buffer_free functions inline functions.
1126 * Disabled command flooding detection support until it's fixed so
1127 that it accepts commands in but does not execute them more than once
1130 * Added silc_net_localhost(), to return local hostname, into
1131 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1132 that must be initialized before calling silc_client_init.
1134 * Added new function: silc_server_send_notify_on_channels to send
1135 notify messages to all channels client has joined. It is assured
1136 that the message is sent only once per client.
1138 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1139 lib/silcutil/silcutil.[ch] as silc_format function. The new
1140 function is generic and is used by server as well, not only by
1141 the logging routines.
1143 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1144 the provided version string was not acceptable. Added new function:
1145 silc_ske_check_version into lib/silcske/silcske.h. The function
1146 must be implemented by the application (client or server) and it
1147 does not reside in the SKE library. The function checks the version
1148 string remote end sent.
1150 * Added back pointers (to opaque context and to SilcSocketConnection)
1151 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1153 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1154 duplicate packet context structure.
1156 * Changed `notify' client operation to send same arguments as client
1157 receives from server except for ID's. ID's are mapped to correct
1158 ID entry and that is returned. Also, if channel entry is not sent
1159 by server but the notify is for channel the channel entry is sent
1160 to application (otherwise application doesn't know that it is for
1161 channel (library gets it from packet's Destination ID)).
1163 * Added silc_client_remove_from_channels into client library to
1164 remove a client from all channels it has joined to. Used when
1165 received SIGNOFF notify from server. Added also new function
1166 silc_client_replace_from_channels to replace old ID entry with
1167 new ID entry on all channels. Used when received NICK_CHANGE
1170 * Fixed ID Cache list handling in silc_idlist_get_client in
1171 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1172 to get (or query) client by ID.
1174 * Updated TODO list.
1176 * Added connection authentication status message defined by the
1177 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1178 support for these into the code in client and server side.
1180 * Added generic function silc_client_send_command to send any command
1181 with variable argument list. Application should use this function
1182 to send commands if the command functions provided by the library
1183 does not suite for the application's user interface needs.
1185 * Added new `failure' client operation. Application is notified about
1186 received failure packet if client is executing a protocol. In this
1187 case the protocol's execution has failed.
1189 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1190 is required by the protocol.
1192 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1193 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1196 * Added status flag to SilcSKE object to indicate realtime status
1197 of the SKE protocol.
1199 * Application receives now exactly same command reply arguments as
1200 the library receives from server. However, if ID is received the
1201 corresponding ID entry is returned to the application (eg. Client
1202 ID is mapped to correct SilcClientEntry entry and that is returned).
1203 Changed command_reply client operation due to this change.
1205 * Changed all ID's in commands and in command replys as ID Payloads.
1206 Change affected both client and server side codes.
1208 All ID's sent in SILC network (with execption of ID's in SILC
1209 Packet header) are sent in ID Payload to support variable length
1212 * Server now notifies nick changes and notifies all clients on
1213 the channels about the new nickname (about the new Client ID,
1216 * Implemented CMODE command to change channel modes. Supports all
1217 channel modes defined by the protocol specs except ban and invite
1218 lists. (Also, private channel key mode is supported but support for
1219 setting private channel key in client is missing, thus, this mode
1220 has no effect on client side (except that server requires that the
1221 client uses private channel key and normal channel traffic does not
1224 Also, invite mode works per se, but INVITE command does not work
1225 yet correctly, so you can set channel as invite only channel but
1226 inviting clients to the channel does not work (it is yet to be
1227 thought what's the best way to do it).
1229 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1230 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1231 Implemented CUMODE command to change user's mode on the channel.
1232 Supports all modes defined by the protocol specs.
1234 * Added NAMES command reply to return users modes on the channel.
1236 * Removed unnecessary and slow ciphers from lib/silccrypt.
1238 * Set SO_KEEPALIVE option to connection sockets by default.
1240 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1242 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1243 redefined the Notify Payload into protocol specs.
1245 * Added silc_id_payload_parse_id to get ID directly from raw
1248 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1251 accept searching by Client ID as well.
1253 * Added support for LEAVE and SIGNOFF notify types in client library.
1255 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1256 to parse ID Payload from raw data.
1258 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Added flags parameter into silc_ske_assemble_security_properties
1261 function in lib/silcske/silcske.[ch].
1263 * Changed notify client operation to fit better for notify messages
1264 sent by server. The notify payload received from server is now
1265 passed to the application (after parsing it to SilcNotifyPayload).
1266 It is application's responsibility to retrieve the arguments
1267 from the payload and show the message the way it wants. The message
1268 sent by server is implementation specific.
1270 * Changed public keys to comply with the protocol specification.
1271 Old public keys are not supported anymore and are not compatible.
1273 * Removed nickname from Channel Payload as the latest draft removed
1274 it. The client must resolve the nickname from the NAMES command
1275 reply received when it joined the channel.
1277 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1279 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Fixed some errors in protocol specification drafts.
1283 * Created lib/silccore/silcnotify.c to implement Notify Payload
1284 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1285 generic payloads described by protocol specifications. The file
1286 includes implementations for ID Payload and Argument Payload.
1288 * Changed Command Payload implementation to use the new Argument
1289 Payload. Changed command_xxxx_payload to command_payload_xxxx
1290 to comply with SILC coding conventions.
1292 * Added suppport for Argument Payload handling in Notify Payload
1293 implementation as protocol requires it. Added the new support
1294 into server and client lib as well.
1296 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added support for multiple nicknames on same channel. [n] is
1299 added locally to the nickname if there are more than one same
1300 nicknames on the channel.
1302 * Server now sends all nicknames that matched WHOIS request.
1303 Client also shows the list received from server.
1305 * Added TOPIC command to client side. User can now set and show
1306 current topic on channel.
1308 * Added MOTD command to client and server. Also, server sends the
1309 motd when client connects to the server.
1311 * Changed version strings to comply ISO 8601.
1313 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Fixed protocol error handling in client library. It should now
1316 cope even if the SKE fails for some reason.
1318 * Made new protocol specification drafts for submitting to IETF.
1320 * Implemented TOPIC command to server in silcd/command.c.
1322 * Added two new notify types into lib/silccore/silcnotify.h:
1323 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1324 notify nickname change and topic setting/change on a channel.
1326 * API change of command_reply operation in client library. The
1327 application gets now the status type received from server as well.
1329 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1331 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1333 * Cras fixed and optimized the packet handling even further and
1334 it should work now. Minor change to the prototype of function
1335 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1337 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1339 * Added new function into lib/silcutil/silcschedule.[ch]:
1340 silc_schedule_with_fd to select() a specified fd. The function
1341 returns after timeout expires or data arrives or goes. The
1342 function is used by packet routines to wait that all data is
1343 received from network.
1345 * Fixed data reading from network in lib/silccore/silcpacket.c.
1346 The code now assures that all data is read from the fd and then
1347 continues packet processing. This was a bug fix since the code
1348 used to drop some data in some circumstances.
1350 * Added new function into lib/silcclient/client.[ch]:
1351 silc_client_start_key_exchange to start key exchange after
1352 connection has been established to server. The code internally
1353 now uses this funtion but its main purpose was to provide it
1354 for applications that perform their own connecting. After
1355 application has created a connection it merely calls this
1356 function to start the key exchange between client and server.
1357 The library takes care of everything else after that.
1359 Updated also lib/silcclient/README to explain the usage of
1362 * Do not send to application information that connection has
1363 been established. Application gets notified it by connect
1366 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Applied cras's patch to add silc_schedule_one function. The
1369 function runs scheduler once and returns.
1371 * Fixed the scheduler after cras messed it up. The timeout
1372 handling works now as it's supposed to work.
1374 * Added into lib/silccore/ silcnotify.h to include notify
1375 message types support. Changed silc_server_send_notify*
1376 functions, in server.[ch], to support those new notify types.
1377 Added the support for the notify types into client library,
1378 as well. Added new notify client operation into ops.h in
1381 * Changed silc_server_packet_send_to_channel to send normal
1382 packets instead of just channel message packets. The function
1383 is now used to send the notify packets to channels. It is not
1384 used to send channel message packets anymore, as server never
1387 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1388 va_arg()s as it seems to require it nowadays. I guess, if SILC
1389 is compiled with older va_arg() the new code should work anyway.
1391 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Splitted core library. Core library (lib/silccore) includes
1394 now only SILC protocol specific core (and common) components.
1395 Created new utility library (lib/silcutil) that includes more
1396 generic purpose stuff. The stuff for util library was taken
1397 from the old core library. This was minor and easy split.
1399 * Created SILC Client Library (lib/silcclient) that includes
1400 implementation of the SILC client without user interface. This
1401 was major move from silc/ directory. The code has been changed
1402 so that it is transparent towards the user interface. The
1403 silc/ directory includes now the same user interface as before
1404 and it uses the new client library. Read lib/silcclient/README.
1405 Basicly, the client library performs everything else related
1406 to SILC except user interface handling. Also, configuration
1407 files are considered to be part of user interface and library
1408 does not handle them.
1410 This change also changed a lot of structures, function naming etc.
1411 Most important change was that SilcClientWindow object was
1412 renamed to SilcClientConnection in the client library. Created
1413 also new file lib/silcclient/ops.h. Also added new files
1414 silc/local_command.[ch] and silc/client_ops.[ch].
1416 All these changes were made to make it easier for user interface
1417 designers to create what ever user interface for the SILC client
1420 It is also expected that the server will be moved to lib
1421 directory as well and SILC Server Library will be created;
1422 sometimes in the future.
1424 * Removed Local commands from lib/silccore/silccommand.h as
1425 they are application specific and new client library does not
1426 handle any of those anymore.
1428 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1429 old client implementation in silc/.
1431 * Added support for callback functions in SILC_LOG_* macros.
1432 Application can now set its own callbacks that will be called
1433 instead of using the default functions that will always print
1434 the debug messages to stderr (or stdout). Also, debugging can
1435 now be disabled by setting silc_debug to FALSE and re-enabled by
1436 setting it to TRUE. Note, that logging will still work even
1437 if debugging is disabled.
1439 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1440 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1441 silc_log_reset_debug_callbacks.
1443 * To enable debugging in silc client one must give now -d
1444 option on command line.
1446 * Changed silc_schedule_init to automatically allocate task queues
1447 if they are not allocated before calling it.
1449 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * Added GMP 3.1 into math library.
1453 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1456 a channel in SILC network. The packet is used by servers and
1457 routers to notify other routers that user has left a channel.
1458 This little feature was missing until now. Added the feature
1459 to protocol specification as well.
1461 Added functions: silc_server_send_remove_channel_user and
1462 silc_server_remove_channel_user into server.[ch].
1464 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1465 lib/silccore/silcpacket.h. However, they are not implemented
1468 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Fixed joining to a channel and sending channel messages
1471 between server and router. The channel message sending should
1472 now work inside a cell.
1474 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Fixed the private message sending between server and router.
1477 The private message sending should now work inside a cell.
1479 * Added silc_server_replace_id into server.[ch] to replace
1480 existing ID in the SILC network.
1482 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1483 and silc_idlist_replace_server_id into idlist.[ch] in server.
1485 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Fixed the server to server connections. Server can again now
1488 connect to router. Router to router connections probably does
1491 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Added dynamic protocol registering support. Now protocols can
1494 registered and unregistered on the fly. Patch by cras.
1496 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Added lib/contrib directory to hold routines that some platforms
1499 don't have but are needed by SILC.
1501 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1502 into lin/contrib to provide getopt() and getopt_long() for
1503 those who don't have it.
1505 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1507 * Added AWAY command to client. When away message is set and
1508 client receives a private message packet the client automatically
1509 replies to the sender with the away message.
1511 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1512 bug seemed to be the cause of recent problems when compiling
1515 * Added version detection support to SKE protocol specification
1516 and added the new changes to the SKE implementation as well.
1517 There were other minor changes in the SKE protocol as well.
1519 Many changes in lib/silcske/silcske.[ch] and in
1520 lib/silcske/payload.[ch].
1522 * Added ^U functionality, clear input line. Patch from cras.
1524 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Mainly small bugfixes on core library. Fixed some debugging
1527 logging and buffer overflow in silclog.c.
1529 * Updated config.sub and config.guess on the distribution tree.
1531 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Added command lagging support in server. Client may execute
1534 commands now only once in two seconds.
1536 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Optimized packet reception. MAC computation and checking is now
1539 also more optimized. A lot previously duplicated code is now
1540 used as generic by both client and server.
1542 * Fixed key pair generation in clientutil.c
1544 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Added into lib/silccore/silcbufutil.[ch] new function;
1547 silc_buffer_realloc.
1549 * Moved generic packet sending/encryption functions to
1550 lib/silccore/silcpacket.[ch] from client and server. Some
1551 rewriting of the functions.
1553 * Moved all generic packet reception/decryption functions to
1554 lib/silccore/silcpacket.[ch] from client and server. The
1555 packet processing is now much cleaner in both client and server.
1556 These were major changes in both client and server.
1558 * Created many common functions in server to do packet sending.
1559 Previously code were duplicated a lot, this has been removed
1562 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Rewrote major parts of the ID cache system. Don't know
1565 whether it is better now or not but at least the API is more
1568 * Major rewrite on ID cache stuff on client because of the ID
1569 cache API changes. Added idlist.c to client.
1571 * Also major rewrite on ID cache stuff on server as well.
1572 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1573 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1574 in hand, instead they are all put into the ID cache system now.
1575 All server_idlist_* routines uses ID cache now instead of
1576 traversing its own lists (those lists does not exist anymore).
1577 SilcIDList though still exists. Also, SilcXXXEntry's are
1580 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Finally made the SKE implementation compliant to the protocol
1583 specification. All mp integers are now binary encoded as
1584 opposed being HEX encoded.
1586 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1589 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1590 functions: silc_[encode/decode]_pem. Also added function
1591 silc_encode_pem_file to PEM encode with newlines ('\n') for
1594 * SILC public keys are now encoded either PEM or binary. Same
1595 option is for private keys as well. By default private keys
1596 are binary encoded and public keys PEM encoded. Silly HEX
1597 encoding were removed.
1599 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1600 function to create fingerprints.
1602 * Fixed a bug in SHA1; does not change the original data anymore.
1604 * Partly implemented INFO command on client and server side.
1605 Fixed CLEAR command. Changes to SERVER command; show current
1606 server(s) when giving command without arguments. Added
1607 VERSION command to client.
1609 * Added check to server that unregistered connections cannot
1610 execute commands (unless it is specificly allowed).
1612 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Fixed screen refresh.
1616 * Fixed channel joining bug from client. On some circumstances
1617 client tried to join to a channel it had already joined.
1619 * Added public key verification process into client's protocol.c.
1620 The client now verifies the public key from user and saves
1621 it into ~./silc/serverkeys/ directory.
1623 Added into: clientutil.[ch]: silc_client_verify_server_key.
1625 * Changed SKE protocol's silc_ske_initiator_finish function
1626 to accept callback function that verifies the received public
1627 key. Removed old silc_ske_verify_public_key function.
1629 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1632 silc_pkcs_private_key[_data]_set.
1634 * Made the password and public authentication more cleaner in
1635 server's protocol.c.
1637 * Removed historic and obsolete protocol `channel_auth' from
1638 both client and server.
1640 * Removed wrong way of sending command status messages from
1641 server to client in server's command.c. The old way violated
1642 protocol specification.
1644 Changes to silccore/silccommand.[ch]: removed
1645 silc_command_encode_status_payload -> not needed anymore,
1646 changed silc_command_encode_payload_va to accept extra
1647 argument on variable argument list. The argument type must
1648 now be provided to the function. Also, added new function:
1649 silc_command_encode_reply_payload_va which is same as
1650 normal command_encode_payload_va except command status type
1651 is provided as extra argument.
1653 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added ~./silc directory handling. The directory includes the
1656 public and private keys for the client.
1658 Added silc_client_check_silc_dir, silc_client_create_identifier
1659 and silc_client_load_keys.
1661 * Implemented SILC protocol compliant public key. Added public
1662 and private key saving to and loading from files.
1664 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1665 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1666 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1667 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1668 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1670 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1671 silc_pkcs_load_[public/private]_key.
1673 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Added silc_server_get_route (route.[ch]) to get connection
1676 data for the fastest route for given ID.
1678 * Implemented INVITE command on client and server. The command
1679 were re-defined in the SILC Protocol Specification and the
1680 implementation now complies with the specification.
1682 * Implemented PING command on client and server.
