1 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Removed the rng context from SilcPacketContext structure and
4 changed that the packet routine uses the Global RNG API.
6 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added support for quit message that client can "leave" on the
9 channel when it quits the SILC. It is ditributed inside the
10 SILC_NOTIFY_TYPE_SIGNOFF notify type.
12 Added silc_server_free_client_data that will take the
13 signoff message as argument.
15 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
17 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Updated parts of the protocol specification to keep it up
22 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
25 payloads in one packet.
27 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
28 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
29 use now the new List flag.
31 * Also deprecated the following packet types: REPLACE_ID,
32 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
34 * Added list support for Notify packet in server.
36 * Added silc_server_send_notify_channel_change to send the
37 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
38 the silc_server_send_replace_id.
40 * Added silc_server_send_notify_nick_change to send the
41 NICK_CHANGE notify type. Deprecates the function
42 silc_server_send_replace_id.
44 * Added silc_server_send_notify_join to send the JOIN notify type.
45 Deprecates the function silc_server_send_new_channel_user.
47 * Added silc_server_send_notify_leave to send LEAVE notify type.
48 Deprecates the function silc_server_send_remove_channel_user.
50 * Added silc_server_send_notify_cmode and
51 silc_server_send_notify_cumode to send CMODE and CUMODE notify
52 types. Deprecates the silc_server_send_set_mode function.
54 * Added SERVER_SIGNOFF notify type to indicate that server has
55 quit. This means that all clients on the channel from that
56 server will drop. This can be also used when netsplit happens.
58 Deprecated REMOVE_ID packet type since it is not needed anymore
61 Added silc_server_send_notify_server_signoff to send the
62 SERVER_SIGNOFF notify type. Deprecates the function
63 silc_server_send_remove_id.
65 Added also silc_server_send_notify_signoff to send the
68 * Employed the PKCS #1. It is the mandatory way to do RSA in the
69 SILC protocol from this day on. Changed the protocol
70 specification as well.
72 * Added silc_server_send_notify_topic_set to send TOPIC_SET
73 notify type. It is used between routers to notify about
74 topic changes on a channel.
76 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
79 * Partly updated the protocol specification to comply with the
80 changes now made. It is still though a bit outdated.
82 * The JOIN notify type now takes one extra argument <Channel ID>.
83 The packet used to be destined to the channel but now the
84 JOIN type may be sent as list thus it is impossible to
85 destine it to any specific channel. By adding this argument
88 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Added CREDITS file. The CHANGES and CREDITS file will appear
91 in the distribution as well.
93 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
96 types in the server's silcd/packet_receive.c.
98 * Implemented CMODE and CUMODE to work in router environment.
100 * Fixed minor encoding and decoding buglet from the
101 lib/silccore/silcmode.c.
103 * Fixed buffer overflow from lib/silcclient/command.c in USERS
106 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
108 * Changed all SilcConfigServer* and silc_config_server* to
109 SilcServerConfig* and silc_server_config*, respectively.
112 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
114 * Associated the ID (client or server ID) to the Authentication
115 Payload to avoid any possibility of forging. Updated the
116 protocol specification and the code accordingly.
118 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * The RSA key length is now save to the RsaKey context in the
121 key generation process in lib/silccrypt/rsa.c. The key length
122 is now used to figure out the maximum size of the block allowed
123 to be encrypted/signed.
125 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
126 is equivalent to the silc_mp_mp2bin but does not allocate any
129 * Changed silc_mp_mp2bin API to take length argument. If it is
130 non-zero then the buffer is allocated that large. If zero, then
131 the size is approximated using silc_mp_sizeinbase, which however
134 * Created Global RNG API which is global RNG that application can
135 initialize. After initializing, any routine anywhere in the
136 code (including library) can use RNG without allocating a new
137 RNG object. This was done to allow this sort of use of the
138 RNG in code that has no chance to allocate RNG object. All
139 applications currently allocate this and many routines in the
140 library use this. Affected file lib/silccrypt/silcrng.[ch].
142 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
143 it to use the Global RNG API.
145 * Defined Authentication Payload into protocol specification that
146 is used during SILC session to authenticate entities. It is
147 used for example by client to authenticate itself to the server
148 to obtain server operator privileges.
150 Implemented this payload into the lib/silccore/silcauth.[ch].
151 Implemented also routines for public key based authentication
152 as the new protocol specification dictates.
154 Moved definitions of different authentication methods from
155 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
157 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
158 silc_pkcs_verify and silc_pkcs_sign_with_hash and
159 silc_pkcs_verify_with_hash functions into the file
160 lib/silccrypt/silcpkcs.[ch].
162 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * The client entry's userinfo pointer must be always valid.
165 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
166 will fail since it requires the userinfo. Now, the userinfo
167 is allocated as "" if actual userinfo does not exist. Actually,
168 it must exist and it is totally Ok to drop client connections
169 that does not announce the userinfo. However, we will make
170 this workaround for now.
172 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
173 to return the remote port by socket.
175 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
178 SILC_SERVER_PENDING_EXEC and added an new macro
179 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
180 data or when error occurs while processing the pending command.
182 Added new argument `destructor' into silc_server_command_pending
183 and to the SilcServerCommandPending object. This destructor is
184 now called after calling the pending callback or if error occurs
185 immediately. If error occurs the actual pending callback won't
186 be called at all - only the destructor. The destructor may be
187 NULL if destructor is not needed.
189 All this applies for client library code as well. Similar
190 changes were made there as well for the pending commands.
192 In the client, the application must now allocate the
193 SilcClientCommandContext with the silc_client_command_alloc
196 * Added reference counter to the SilcServerCommandContext. Added
197 function silc_server_command_alloc and silc_server_command_dup
200 Same type of functions added to the client library for the same
203 * Removed the cmd_ident from IDListData away since it is now
204 global for all connections. It is the command identifier used
205 in command sending and with pending commands. The affected file
208 * Added reference counter to the SilcSocketConnection objecet to
209 indicate the usage count of the object. The object won't be
210 freed untill the reference counter hits zero. Currently only
211 server uses this, and client ignores it. The client must be
212 set to use this too later. The affected files are
213 lib/silccore/silcsockconn.[ch]. Added also the function
214 silc_socket_dup to increase the reference counter.
216 This was mainly added because it is possible that the socket
217 is removed underneath of pending command or other async
218 operation. Now it won't be free'd and proper DISCONNECTING
219 flags, etc. can be set to avoid sending data to connection that
220 is not valid anymore.
222 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
223 the connection. After that it sets SILC_SET_DISCONNECTED.
224 It is, however, possible that the socket data is not still freed.
225 The silc_server_packet_process now checks that data is not
226 read or written to connection that is DISCONNECTED. The socket
227 get's freed when the reference counter hits zero.
229 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Changed the client operation API: channel_message operation's
232 `sender' is now the client entry of the sender, not the nickname
233 and the `channel' is the channel entry, not the channel name.
235 In the private_message operation the `sender' is now also the
236 client entry of the sender not the nickname.
238 Affected file is lib/silcclient/ops.h and all applications
239 using the client operations.
241 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Moved the calling of ops->connect() from connect_to_server_final
244 into receive_new_id functin since that is the point when the
245 client is actually allowed to send traffic to network. The
246 affected file is lib/silcclient/client.c.
248 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
251 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
252 (if needs broadcasting) instead of broadcasting the packets one
253 by one which would make a burst in the network traffic.
255 * Added `broadcast' argument to the functions in silcd/server.[ch]
256 silc_server_create_new_channel[_with_id] to indicate whether
257 to send New Channel packet to primary router.
259 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
261 * Added new function into the silcd/server.[ch] files:
262 silc_server_create_new_channel_with_id to create new channel with
263 already existing Channel ID.
265 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
266 lib/silccore/silcpacket.h. This packet is used t send list of
267 Set Mode payloads inside one packet. Server uses this to set
268 the modes for the channels and clients on those channels, that it
269 announced to the router when it connected to it. The protocol
270 specification has been updated accordingly.
272 * The silc_server_new_channel did not handle the packet coming
273 from normal server as it normally does not send that. However,
274 when it announces its channels it does send it. Implemented
275 the support for that.
277 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
278 into the file lib/silccore/id.h.
280 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Fixed memory leaks in the functions silc_idlist_del_client,
283 silc_idlist_del_channel and silc_idlist_del_server in the file
284 silcd/idlist.c. All of those leaked like a sieve.
286 * Fixed some small memory leaks in the client's function
287 silc_client_notify_by_server.
289 * Added functions into silcd/server.c: silc_server_announce_clients,
290 silc_server_announce_channels and silc_server_announce_server.
291 These functions are used by normal and router server to announce
292 to its primary router about clients, channels and servers (when
293 router) that we own. This is done after we've connected to the
296 These functions effectively implements the following packet types:
297 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
298 and SILC_PACKET_NEW_ID_LIST.
300 * Added new functions into the silcd/packet_receive.[ch]:
301 silc_server_new_id_list, silc_server_new_channel_list and
302 silc_server_new_channel_user_list to handle the incoming
303 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
305 * Added support of changing Channel ID in the function
306 silc_server_replace_id. If the server that announces a channel
307 to the router already exists in the router (with same name but
308 with different Channel ID), router is responsible to send
309 Replace ID packet to the server and force the server to change
310 the Channel ID to the one router has.
312 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
313 client that the Channel ID has been changed by the router. The
314 normal server sends this to the client. Client must start using
315 the new Channel ID as the channel's ID.
317 Implemented handling of this new type into lib/silcclient/client.c
318 into the function silc_client_notify_by_server.
320 * Added new function silc_idlist_replace_channel_id into the files
321 silcd/idlist.[ch] to replace the Channel ID.
323 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * Call silc_server_command_identify_check always when processing
326 the IDENTIFY command in silcd/command.c
328 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
331 send keepalive packets. The packet can be sent by clients,
334 Added function silc_socket_set_heartbeat into the file
335 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
336 If not set, the heartbeat is not performed. The actual
337 heartbeat is implemented in the low level socket connection
338 library. However, application is responsible of actually
341 Added silc_server_send_heartbeat to send the actual heartbeat
342 packet into silcd/packet_send.[ch]. Server now performs
343 keepalive with all connections.
345 * Added silc_task_get_first function into lib/silcutil/silctask.c
346 to return the timeout task with shortest timeout. There was a bug
347 in task unregistration that caused problems. TODO has been
348 updated to include that task system must be rewritten.
350 * The client library will now resolve the client information when
351 receiving JOIN notify from server for client that we know but
352 have incomplete information.
354 * Rewrote parts of silc_server_remove_from_channels and
355 silc_server_remove_from_one_channel as they did not remove the
356 channel in some circumstances even though they should've.
358 * Encryption problem encountered in server:
360 The LEAVE command used to send the Channel Key packet to the
361 router immediately after generating it. However, the code
362 had earlier sent Remove Channel user packet but not immediately,
363 ie. it was put to queue. The order of packets in the router
364 was that Channel Key packet was first and Remove Channel User
365 packet was second, even though they were encrypted in the
366 reverse order. For this reason, MAC check failed. Now, this
367 is fixed by not sending the Channel Key packet immediately but
368 putting it to queue. However, this is more fundamental problem:
369 packets that are in queue should actually not be encrypted
370 because packets that are sent immediately gets encrypted
371 actually with wrong IV (and thus MAC check fails). So, packets
372 that are in queue should be encrypted when they are sent to
373 the wire and not when they put to the queue.
375 However, the problem is that the current system has not been
376 designed to work that way. Instead, the packet is encrypted
377 as soon as possible and left to the queue. The queue is then
378 just purged into wire. There won't be any fixes for this
379 any time soon. So, the current semantic for packet sending
382 o If you send packet to remote host and do not force the send
383 (the packet will be in queue) then all subsequent packets to the
384 same remote host must also be put to the queue. Only after the
385 queue has been purged is it safe again to force the packet
388 o If you send all packets immediately then it safe to send
389 any of subsequent packets through the queue, however, after
390 the first packet is put to queue then any subsequent packets
391 must also be put to the queue.
393 Follow these rules and everything works fine.
395 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Added new function silc_server_remove_clients_by_server to
398 remove all client entries from ID list when the server connection
399 is lost. In this case it is also important to invalidate all
400 client entires as they hold the invalid server entry. This
401 fixes fatal bug when server has lost connection and will reconnect
404 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Made some sanity checks to silc_server_daemonise like to check
407 whether the requested user and group actually exists.
409 * Added sanity check to SKE's silc_ske_responder_finish to check
410 that the public and private key actually is valid.
412 * Invalidate the client's nickname when receiving Replace ID
413 packet and the Client ID is being replaced. This means that the
414 server will query the nickname if someone needs it (client)
417 * Sort the ID Cache in client library when the ID Cache data
418 has changed (needs sorting).
420 * Do not allow for SILC client to create several connections to
421 several servers. The client does not support windows right now
422 and generating multiple connections causes weird behaviour.
424 Irssi-silc client does support windows and can handle several
425 connections without problems, see: www.irssi.org and SILC plugin.
427 * Fixed some places where client was added to the IDList. The
428 rule of thumb is following (in order to get everything right):
429 If the client is directly connected local client then the
430 `connection' argument must be set and `router' argument must be
431 NULL to silc_idlist_add_client function. If the client is not
432 directly connected client then the `router' argument must
433 bet set and the `connection' argument must be NULL to the
434 silc_idlist_add_client function.
436 * The funtion silc_server_packet_send_local_channel actually did
437 not check whether the client was locally connected or not. It
438 does that now. Fixed a bug related to LEAVE command.
440 * Fixed Remove Channel User payload parsing bug in server's
441 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
443 * The server's silc_server_save_channel_key now checks also the
444 global ID list for the channel as it might not be in the local
445 list. Fixed a bug related to LEAVE command.
447 * Is this the end of the [<unknown>] buglet that has been lurking
448 around for a long time? A little for loop fix in server's
449 silc_server_command_whois_parse that is used by both IDENTIFY
450 and WHOIS command. At least, this was a clear bug and a cause
451 of one type of [<unknown>] buglet.
453 * WHOIS and IDENTIFY commands call the function
454 silc_server_command_[whois/identify]_check function even if
455 we are not router server.
457 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Added --with-gmp configuration option. If set the GMP
460 is always compiled in the SILC source tree. If not set then
461 it is checked whether the system has the GMP3 installed. If
462 it has then the GMP won't be compiled (the system's headers
463 and library is used), if it doesn't have it then the GMP is
464 compiled in the SILC source tree.
466 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Changed RSA private exponent generation to what PKCS #1
469 suggests. We try to find the smallest possible d by doing
470 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
471 not security fix but optimization.
473 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Added new config entry [Identity] to fork the server and run
476 it as specific user and group. A patch from Bostik.
478 * Imported Dotconf configuration library into lib/dotconf.
479 This will be used to create the SILC configuration files later.
480 It will appear in the distsribution after this commit.
482 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * A big code auditing weekend happening. Auditing code for
485 obvious mistakes, bugs and errors. Also, removing any code
488 Removed files for being obsolete:
490 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
491 inline in the file lib/silcutil/silcbuffer.h)
493 o lib/silcutil/silcbufutil.c (the header has inline versions)
495 Changed code to fix possible error conditions:
497 o The buffer formatting routines now check that the destination
498 buffer really has enough space to add the data. This applies for
499 both buffer formatting and unformatting
500 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
501 unformatting was changed to accomodate following rules:
502 XXX_*STRING_ALLOC will allocate space for the data into the pointer
503 sent to the function while XXX_*STRING will not allocate or copy
504 the data into the buffer. Instead it sets the pointer from the
505 buffer into the pointer sent as argument (XXX_*STRING used to
506 require that the pointer must be allocated already). This change
507 makes this whole thing a bit more consistent and more optimized
508 (note that the data returned in the unformatting with XXX_*STRING
509 must not be freed now). The routines return now -1 on error.
511 o Tried to find all code that use buffer_format and buffer_unformat
512 and added return value checking to prevent formatting and
513 especially unformatting errors and possible subsequent fatal
516 o Changed ske->x and ske->KEY to mallocated pointers in
517 lib/silcske/silcske.h. Fixed possible data and memory leak.
519 o Added return value checking to all *_parse* functions. Fixed
520 many memory leaks as well.
522 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
523 so that buffer overflows would not happen. All code now also
524 checks the return value as it can fail.
526 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Added reconnection support to server if the normal server looses
529 its connection to the router (for example if router is rebooted).
530 The server performs normal reconnection strategy implemented
531 to the server. Affected file silcd/server.c.
533 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Added new packet type SILC_PACKET_SET_MODE that is used to
536 distribute the information about changed modes (for clients,
537 channels and clients channel modes) to all routers in the
538 network. Updated the protocol specification accordingly.
540 Added functions into silcd/packet_send.c and
541 silcd/packet_receive.c: silc_server_send_set_mode,
542 silc_server_set_mode.
544 Added new files silcmode.[ch] into lib/silccore that implements
545 the encoding and decoding of Set Mode Payload. Added new type
546 SilcSetModePayload. Moved the definitions of different modes
547 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
549 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Oops, a little mistake in server's connection authentication
552 protocol. The protocol is not ended with FAILURE but with
553 SUCCESS if the authentication is Ok. :) Affected file is
556 * Implemented NICK_CHANGE notify handling in server in the file
557 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
558 the local clients on the channel. After the changing nickname
559 in router environment snhould work and the [<unknown>] nickname
560 should appear no more.
562 The silc_server_replace_id function that receives the Replace ID
563 payload now sends the NICK_CHANGE notify type also in the file
564 silcd/packet_receive.c
566 * Changed WHOIS and IDENTIFY command to support the maximum amount
567 of arguments defined in protocol specs (3328 arguments). This
568 fixed a bug that caused problems when there were more than three
571 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
573 * Added extra parameter, command identifier, to the
574 silc_client_send_command so that explicit command identifier
577 Changed that ID list routines uses specific command identifier
578 when sending WHOIS/IDENTIFY requests to the server so that they
579 can be identified when the reply comes back.
581 Affected files lib/silcclient/command.[ch],
582 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
584 * Added `sender' argument to silc_server_packet_send_to_channel
585 to indicaet the sender who originally sent the packet to us
586 that we are now re-sending. Ignored if NULL. Affected file
587 silcd/packet_send.[ch].
589 * Added some server statistics support in silcd/server_internal.h
590 SilcServerStatistics structure and around the server code. Also
591 send some nice statistics information when client is connecting
594 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Fixed channel ID decoding in server's JOIN command reply in
597 silcd/command_reply.c
599 * Fixed braodcasting of replace ID payload to not to send it if
600 we are standalone server in silcd/packet_receive.c.
602 * Fixed all channel message sending routines to not to send
603 packets to clients that has router set, since they are routed
604 separately in the same function earlier. Affects file
605 silcd/packet_send.c and all channel packet sending functions.
607 * In USERS reply, res_argv[i] are not allocated, the table
608 is allocated. Thus changed that free the table, not its
611 * In server's whois_check and identify_check if the client is
612 locally connected do not send any WHOIS commands - they are not
615 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Fixed some minor bugs in client when sending WHOIS command. The
618 arguments was in wrong order.
620 * Removed statis function add_to_channel from server in
621 silcd/command.c that was previously used with the joining but
624 * Tested USERS command in router environment successfully with two
625 routers, two servers and two clients.
627 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Reorganized the USERS command and command reply in client library
630 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
631 When the command is given by user we register a pending command
632 callback that will reprocess the command after the reply has been
633 received from the server. When reprocessing the packet we then
634 display the information. Thus, the USERS information is displayed
635 now in the command callback instead of in the command reply
636 callback. The processing of the command is same as previously
637 when server has sent the command reply in the JOINing process.
639 * Added to USERS command in silcd/command_reply.c to join the client,
640 we didn't use to know about, to the channel after we've created
641 a client entry for it. Also, for clienet we did know already still
642 check whether it is on the channel or not and add it if not.
644 * Removed silc_server_command_join_notify as the function and its
647 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Changed the client's pending command handling to the same as the
650 server's pending command handling. It is also now possible to
651 execute command reply functions from other command reply
652 function as the function callbacks for commands and command
653 replies are one and same. The pending commands are not static
654 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
655 in client connection context. Thus, pending commands are server
656 connection specific as it is convenient.
658 Changed the function silc_client_command_pending and
659 silc_client_command_pending_del and added new function
660 silc_client_command_pending_check. Removed the
661 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
664 * Added cmd_ident, current command identifier, to the client
665 connection context in lib/silcclient/client.h to keep track on
666 command identifiers used in command sending. Client's command reply
667 function handling now supports the mandatory command identifiers.
669 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
670 funtions in client to fully support pending command callbacks.
672 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
673 as one of the arguments to the application in the command reply
676 * NOTE: The FORWARDED flag is depracated. It used to be depracated
677 before first releasing SILC but came back. Now it is removed again
678 and should come back nomore. The FORWARDED flag was used only
679 by the JOINing procedure by forwarding the command packet to router.
680 Now, the JOINing procedure has been changed to more generic (due
681 to various router environment issues) and FORWARDED is not needed
682 anymore for anything. The protocol specification is yet to be
685 Now, removed silc_server_packet_forward from server and the flag
686 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
688 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
690 * Renamed NAMES command to USERS command. The NAMES was named that
691 due to historical reasons. Now it is renamed. Also, rewrote
692 parts of the USERS command. The nickname list is not sent anymore
693 by the server. Only Client ID and mode lists are sent in the USERS
694 command. Changed this also to the protocol specification.
696 The client now resolves the names and stuff after it receives
697 the USERS list from the server when joining to the channel.
699 * WHOIS and IDENTIFY commands has been changed to support multiple
700 Client ID's per command. One can now search for multiple users
701 in the network by sending only one WHOIS or IDENTIFY command.
702 Changed the code and the protocol specifications.
704 * Removed silc_server_command_identify_parse and changed that IDENTIFY
705 uses silc_server_command_whois_parse to parse the request. */
707 * If normal server, do not parse the WHOIS and IDENTIFY requests
708 before sending it to the router. Saves some time.
710 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Fixed JOIN command on client library. Wrong number of arguments
713 used to crash the client.
715 * Added silc_server_channel_has_global function to check whether
716 channel has global users or not.
718 * Added silc_server_channel_has_local function to check whether channel
719 has locally connected clients on the channel.
721 * The silc_server_remove_from_one_channel now checks whether the
722 channel has global users or not after given client was removed from
723 the channel. It also checks whether the channel has local clients
724 on the channel anymore. If it does not have then the channel entry
725 is removed as it is not needed anymore.
727 * The silc_server_notify now checks on JOIN notify whether the joining
728 client is one of locally connected or global. If it is global then
729 the channel has now global users on the channel and that is marked
730 to the channel entry. Also, it now saves the global client to
731 global list who is joining and JOINs it to the channel. This is
732 for normal server, that is.
734 Changed silc_server_send_notify_on_channel,
735 silc_server_packet_relay_to_channel and
736 silc_server_packet_send_to_channel check if we are normal server
737 and client has router set (ie. global client) do not send the
738 message to that client, as it is already routed to our router.
740 * Implemented LEAVE notify type handling in silc_server_notify
743 * Tested LEAVE command in router environment successfully. Tested
744 with two routers, two servers and two clients.
748 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
750 * Implemented SIGNOFF notify type handling in silc_server_notify
753 * silc_server_remove_id now removes the client entry from all channels
754 it has joined and thusly sends SIGNOFF notify type.
756 * Rewrote the NAMES list generation in server by removing two excess
757 loops. The lists are created now inside one loop.
759 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * silc_server_remove_channel_user checks now also global list
762 for channel and client.
764 * silc_server_new_channel_user checks now both local and global
765 list for channel and client. Fixed a bug in client id decoding.
766 Used to decode wrong buffer.
768 * silc_server_channel_message checks now both local and global
769 list for channel entry.
771 * Tested channel joining (hence JOIN) in router environment
772 successfully. Tested with two routers, two servers and two
775 * Tested channel message sending in router environment successfully.
777 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Added silc_server_save_channel_key into server.[ch] to save the
780 received channel key in Channel Key payload processing. It is
781 also used in JOIN command reply handling.
783 Equivalent function silc_client_save_channel_key added into
784 client.[ch] into client library.
786 * Changed JOIN command reply to send information whether the channel
787 was created or not (is existing already) and the channel key
788 payload. Changed protocol specs accordingly.
790 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
791 the request was sent by ID and not by nickname. Crashed on
794 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
796 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
797 now correctly save the received data.
799 * silc_server_free_sock_user_data now notifies routers in the
800 network about entities leaving the network.
802 At the same time implemented functions silc_server_remove_id
803 and silc_server_send_remove_id to receive and send REMOVE_ID
804 packets. The packet is used to notify routers in the network
805 about leaving entities. The ID removed will become invalid in
808 * Added function silc_idlist_del_server into server. Removes and
809 free's server entry from ID list.
811 * silc_server_private_message function now checks, if we are router,
812 that the destination ID really is valid ID, naturally.
814 * In router when NEW_ID packet is received (for new client) the
815 hash of the Client ID is saved in the ID Cache but the
816 client->nickname is set to NULL, instead of putting the hash
819 IDENTIFY command now also checks that client->nickname must be
820 valid. If it is not if will request the data from the server who
821 owns the client. Added new function
822 silc_server_command_identify_check.
824 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
825 to set the command to already allocated Command Payload.
827 * Tested private message sending in router environment with two
828 routers, two servers and two clients. Fixed minor bugs and now
831 * Fixed segfault from client's NAMES command. Used to crash if
834 * Forwarded packets must not be routed even if it is not destined
835 to the receiver. Changed server code comply with this.
837 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Added `require_reverse_mapping' boolean value to ServerParams
840 structure. If TRUE (not default) the server will require that
841 the connecting host has fully qualified domain name.
843 If the reverse mapping is not required and hostname could not be
844 found the IP address is used as hostname.
846 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Implemented version string checking to both client and server.
849 The check is incomplete currently due to the abnormal version
850 strings used in development version of SILC.
852 * Changed all command functions in server to use the new
855 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Changed char *data to unsigned char *data in ID Cache system to
858 support binary data as ID Cache data. Changed code to support
859 binary data in lib/silccore/idcache.c.
861 * Renamed silc_server_packet_relay_command_reply to
862 silc_server_command_reply as it is normal packet receiving
863 function. Rewrote the function to accept command replys for
864 servers and not only for clients.
866 * Mark remote router always as registered server if we are connecting
867 to it. Otherwise, commands sent by the router to us are ignored.
869 * All ID List find routines now returns the ID Cache Entry pointer
870 as well if requested.
872 * WHOIS command works now in router environment, tested with two
873 routers, two servers and two clients.
875 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
876 in router environment (as it is almost equivalent to WHOIS) but
877 hasn't been tested thoroughly. Added new functions:
879 silc_server_command_identify_parse
880 silc_server_command_identify_send_reply
881 silc_server_command_identify_from_client
882 silc_server_command_identify_from_server
884 * Disabled route cache adding because adding two different ID's with
885 same IP replaces the old cache entry thus giving wrong route.
886 The entry->router->connection is always the fastest route anyway
887 so route cache may not be needed. Of course, new routes maybe
888 established after receiving the ID when the entry->router->connection
889 might not be anymore the most optimal.
891 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Add route cache for received ID for fast routing.
895 * Added silc_server_packet_route to route received packet on router
896 that is not destined to us.
898 * Renamed silc_server_get_route to silc_server_route_get.
900 * Added id_string and id_string_len fields into SilcServer to
901 include encoded ServerID for fast comparing without excess
902 encoding of the ID's.
904 * Cleaned up WHOIS command on server side. Added following static
907 silc_server_command_whois_parse
908 silc_server_command_whois_check
909 silc_server_command_whois_send_reply
910 silc_server_command_whois_from_client
911 silc_server_command_whois_from_server
913 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
914 arguments in command replies. All command functions should be
915 updated to use this macro.
917 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Minor typo fixes on command reply handling on server.
921 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Added silc_server_command_add_to_channel internal routine to add
924 the client to the channel after router has created the channel and
925 sent command reply to the server.
927 * Added generic silc_server_send_command to send any command from
930 * Use static buffer with ID rendering instead of duplicating data.
932 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Fixed a channel user mode bug when joining to a channel server gave
935 everybody channel founder rights, oops.
937 * We mark ourselves as the router of the incoming server connection
938 if we are router ourselves. This way we can check in some packet
939 sending functions whether it is locally connected server. For
940 incoming router connections we put NULL.
942 * For router sending packets locally means now always sending the
943 packet cell wide; to local clients and local servers. For normal
944 server sending packet locally means sending it to only local
947 * Fixed the JOIN command to really work in router environment. If the
948 channel is created it is always created by the router. Router is
949 also responsible of making the initial joining to the channel,
950 sending JOIN notify to the sending server and distributing
951 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
952 does not exist server doesn't do anything else but forward the
953 command to the router which performs everything.
955 * Added silc_server_send_channel_key function to send the Channel Key
958 * Added silc_server_create_channel_key to create new channel key. The
959 channel key is now re-generated everytime someone joins or leaves
960 a channel, as protocol dictates. Note: channel->key_len is the
963 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Splitted server.[ch] finally. Created now packet_send.[ch] and
966 packet_receive.[ch] to separate packet sending and receiving
967 routines. The server.[ch] now includes everything else including
968 actual packet processing (writing and reading data) and other
971 Renamed silc_server_private_message_send_internal to
972 silc_server_send_private_message. The routine is still though
973 used only to relay private messages as server does not send
974 private messages itself.
976 Renamed silc_server_new_channel to silc_server_create_new_channel
977 and added new function sicl_server_new_channel that handles the
978 incoming New Channel packet. Added also new sending function
979 silc_server_send_new_channel to send New Channel Payload.
981 * Added new function silc_server_notify to process incoming notify
982 packet to the server/router. Server may then relay the notify
983 to clients if needed.
985 * Added new function silc_server_new_channel_user to process incoming
986 New Channel User packet. Router will redistribute the packet and
987 send JOIN notify to its local clients and locally connected servers
988 if needed. Normal server will send JOIN notify to its local client
989 on same channel when received this packet. Added also corresponding
990 sending function silc_server_send_new_channel_user to sent the
993 * Added boolean route argument to send_notif_to_channel and
994 packet_send_to_channel functions to attempt to route the packet
995 if it is TRUE and send only locally if it is FALSE.
997 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * silc_server_replace_id now broadcasts the received replace ID
1000 packet if it is not broadcast packet already. The router must
1001 broadcast to inform other routers about changed ID.
1003 * Added backpointer to server's router into SilcServer context in
1004 silcd/server_internal.h.
1006 * Fixed silc_server_packet_broadcast to send correct broadcast
1009 * The channel key is now distributed to the local client as soon
1010 as it is received from the router (in router environment) so that
1011 no other packet may be sent for the channel until client has
1014 * silc_server_remove_channel_user now broadcasts the received
1015 Remove Channel User packet if it is not broadcast packet already.
1016 The router must broadcast to inform other routers about removed
1019 * Added users field into SilcPacketContext that is a reference count
1020 of the context. One can increase the reference count by calling
1021 silc_packet_context_dup which is now changed to just increase the
1022 reference count instead of duplicating the data. The reference
1023 count is decresed by calling silc_packet_context_free that will
1024 free the data after the reference count hits zero.
1026 For now on the packet context and everything allocated into it
1027 (including the raw packet from network) must be freed by calling
1028 the new silc_packet_context_free function. Added also new function
1029 silc_packet_context_alloc that must be used now to allocate the
1030 context. This also means that if a routine is asynchronous from
1031 silc_[client/server]_packet_parse_type the packet context must
1032 be duplicated by calling silc_packet_context_dup. Otherwise it
1033 gets free'd after silc_[client/server]_packet_parse_type returns.
1034 Also, one must remember that if packet is duplicated then its
1035 reference count must be decresed by calling the free function as
1036 many times as it was duplicated.
1038 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1039 from both client and server.
1041 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * Made joining to a channel working in router environment.
1045 * Cleaned up JOIN command on server side and create function
1046 silc_server_command_join_channel internal routine to make the
1049 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Changed silc_command_pending list to SilcDList. Also, added
1052 `ident' field to SilcServerCommandPending structure to identify
1053 the reply and to call correct callback.
1055 Added silc_server_command_pending_check function to replace the
1056 corresnponding macro. The silc_command_pending list is not
1059 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1060 to set identifier to previously allocated Command Payload. It
1061 is used to set identifier for command when resending Command
1064 * Added silc_command_payload_encode_payload to encode Command
1065 Payload buffer from SilcCommandPayload structure.
1067 * Added silc_argument_payload_encode_payload to encode Argument
1068 payload buffer from SilcArgumentPayload structure.
1070 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Changed WHOIS command to support router connection on server side.
1073 The whois request is always sent to router unless the server is
1074 standalone server. After server has received the reply from the
1075 router will it send the reply to the client.
1077 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1078 broadcast received broadcast packet. The function is used only
1079 by router. The broadcast packet is always sent to the router's
1082 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1083 render given ID to printable string, for log files for example.
1085 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Made basic router to router connections working. At least they
1088 can now connect to each other but nothing really works the way
1089 they are supposed - yet.
1091 * Added new initiator token to RouterConnection configuration
1092 file in silcd/serverconfig.[ch]. It is used to tell whether we
1093 are the initiator to the remote router or whether we'll expect
1094 the other end to connect.
1096 * Moved registering of listener task to silc_server_init, hence
1097 the server starts listenning as soon as it is run, even if it
1098 does not have connections to other routers. Let's see how well
1101 * Changed default connection retry timeouts for more suitable in
1104 * Removed cipher and such arguments from silc_idlist_add_client
1105 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1106 Added new function silc_idlist_add_data to add the keys and stuff
1109 * Added SilcIDListData structure and added it to SilcClientEntry
1110 and SilcServerEntry as their first field in the structure. This
1111 way we can explicitly cast the ID entries to the SilcIDListData
1112 structure and get common data for the entries. In past, we had
1113 to first check what type of connection it is and then cast it to
1114 correct ID entry type. Now, we can directly cast the opaque
1115 pointer to the SilcIDListData (no matter what ID entry it actually
1116 is) and get the data needed.
1118 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1121 in some circumstances even if threre were timeout tasks, though not
1122 IO tasks, but tasks anyway. Now fixed.
1124 * Defined SilcServerConnection structure to hold connection specific
1125 stuff about directly connected servers and routers. The definition
1126 is currently in silcd/server_internal.h. I thought about having
1127 a bit more important role fro this struct but for now it is used
1128 only when connecting to other server (or router actually).
1130 * Added connecting retry support in server when connecting to
1131 router(s). The retry feature implement exponential backoff
1132 algorithm. Also, added SilcServerParams structure to hold default
1133 parameters for server. For now, it include these retry settings
1134 and are hard coded. After server is moded to be as Silc Server
1135 Library this structure will be more important.
1137 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Changed client librarys channel->clients table to SilcList and
1140 changed code accordingly.
1142 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Changed client's channel table to SilcList and changed code
1145 accordingly. Also changed SilcChannelClientEntry to include back-
1146 pointer to the channel so that client entry can use that structure
1147 as list as well and we have fast cross-reference to the channel.
1148 This change dramatically decreased the complexity of channel
1149 handling with client entry and vice versa (removed one extra
1150 loop when searching for channel entry from many functions).
1152 * Changed server->sim from table to SilcDList and changed code
1155 * NAMES command can now be used from user interface. It will show
1156 the user list on the channel, neatly.
1158 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1159 Code now saves realname of the user if it becomes available.
1161 * Renamed configure.in to configure.in.pre and made ./prepare
1162 script to automatically add correct version string to
1163 configure.in which it creates from configure.in.pre.
1165 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * NAMES command reply now shows users mode with the nickname when
1170 * Moved silc_client_ch[u]mode[_char] functions from
1171 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1172 place sucks, they are utility functions and should be in some
1175 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1177 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1180 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Added TRQ (efficient deque and list library) into lib/trq. This is
1185 a very good list library that is currently used in the SILC. Defined
1186 SilcList API over the library because I didn't like the API very
1187 much. See lib/trq/silclist.h for the API and examples of how to
1188 use the API. Fixed various places in the code to use the new
1189 SilcList API. The SilcList is meant for lists that has a structure
1190 already defined as a list. It is not suitable to add just some
1191 context to the list (in TRQ, the context is the list actually).
1193 So, I defined SilcDList that can be used for the purpose where
1194 predefined list structure does not exit. This can be used as
1195 such list. Now some context just can be added to the SilcDList.
1196 Currently this list is not used in the SILC just yet, though there
1197 are a lot places where this can replace dynamically allocated
1198 tables and I will fix these places, later, to use SilcDList.
1199 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1200 and use TRQ internally).
1202 Also fixed some annoying warning messages that the original TRQ
1203 code generated. Also minor changes to TRQ's Makefile.in.
1205 * Added support for querying by Client ID to both WHOIS and
1206 IDENTIFY commands into server, as required by the protocol.
1208 * Removed method function pointers from SilcBuffer structure. They
1209 weren't used to anything and just increased the context size for
1210 no good reason. This change also made silc_buffer_alloc and
1211 silc_buffer_free functions inline functions.
1213 * Disabled command flooding detection support until it's fixed so
1214 that it accepts commands in but does not execute them more than once
1217 * Added silc_net_localhost(), to return local hostname, into
1218 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1219 that must be initialized before calling silc_client_init.
1221 * Added new function: silc_server_send_notify_on_channels to send
1222 notify messages to all channels client has joined. It is assured
1223 that the message is sent only once per client.
1225 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1226 lib/silcutil/silcutil.[ch] as silc_format function. The new
1227 function is generic and is used by server as well, not only by
1228 the logging routines.
1230 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1231 the provided version string was not acceptable. Added new function:
1232 silc_ske_check_version into lib/silcske/silcske.h. The function
1233 must be implemented by the application (client or server) and it
1234 does not reside in the SKE library. The function checks the version
1235 string remote end sent.
1237 * Added back pointers (to opaque context and to SilcSocketConnection)
1238 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1240 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1241 duplicate packet context structure.
1243 * Changed `notify' client operation to send same arguments as client
1244 receives from server except for ID's. ID's are mapped to correct
1245 ID entry and that is returned. Also, if channel entry is not sent
1246 by server but the notify is for channel the channel entry is sent
1247 to application (otherwise application doesn't know that it is for
1248 channel (library gets it from packet's Destination ID)).
1250 * Added silc_client_remove_from_channels into client library to
1251 remove a client from all channels it has joined to. Used when
1252 received SIGNOFF notify from server. Added also new function
1253 silc_client_replace_from_channels to replace old ID entry with
1254 new ID entry on all channels. Used when received NICK_CHANGE
1257 * Fixed ID Cache list handling in silc_idlist_get_client in
1258 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1259 to get (or query) client by ID.
1261 * Updated TODO list.
1263 * Added connection authentication status message defined by the
1264 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1265 support for these into the code in client and server side.
1267 * Added generic function silc_client_send_command to send any command
1268 with variable argument list. Application should use this function
1269 to send commands if the command functions provided by the library
1270 does not suite for the application's user interface needs.
1272 * Added new `failure' client operation. Application is notified about
1273 received failure packet if client is executing a protocol. In this
1274 case the protocol's execution has failed.
1276 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1277 is required by the protocol.
1279 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1280 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1283 * Added status flag to SilcSKE object to indicate realtime status
1284 of the SKE protocol.
1286 * Application receives now exactly same command reply arguments as
1287 the library receives from server. However, if ID is received the
1288 corresponding ID entry is returned to the application (eg. Client
1289 ID is mapped to correct SilcClientEntry entry and that is returned).
1290 Changed command_reply client operation due to this change.
1292 * Changed all ID's in commands and in command replys as ID Payloads.
1293 Change affected both client and server side codes.
1295 All ID's sent in SILC network (with execption of ID's in SILC
1296 Packet header) are sent in ID Payload to support variable length
1299 * Server now notifies nick changes and notifies all clients on
1300 the channels about the new nickname (about the new Client ID,
1303 * Implemented CMODE command to change channel modes. Supports all
1304 channel modes defined by the protocol specs except ban and invite
1305 lists. (Also, private channel key mode is supported but support for
1306 setting private channel key in client is missing, thus, this mode
1307 has no effect on client side (except that server requires that the
1308 client uses private channel key and normal channel traffic does not
1311 Also, invite mode works per se, but INVITE command does not work
1312 yet correctly, so you can set channel as invite only channel but
1313 inviting clients to the channel does not work (it is yet to be
1314 thought what's the best way to do it).
1316 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1317 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1318 Implemented CUMODE command to change user's mode on the channel.
1319 Supports all modes defined by the protocol specs.
1321 * Added NAMES command reply to return users modes on the channel.
1323 * Removed unnecessary and slow ciphers from lib/silccrypt.
1325 * Set SO_KEEPALIVE option to connection sockets by default.
1327 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1329 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1330 redefined the Notify Payload into protocol specs.
1332 * Added silc_id_payload_parse_id to get ID directly from raw
1335 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1338 accept searching by Client ID as well.
1340 * Added support for LEAVE and SIGNOFF notify types in client library.
1342 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1343 to parse ID Payload from raw data.
1345 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Added flags parameter into silc_ske_assemble_security_properties
1348 function in lib/silcske/silcske.[ch].
1350 * Changed notify client operation to fit better for notify messages
1351 sent by server. The notify payload received from server is now
1352 passed to the application (after parsing it to SilcNotifyPayload).
1353 It is application's responsibility to retrieve the arguments
1354 from the payload and show the message the way it wants. The message
1355 sent by server is implementation specific.
1357 * Changed public keys to comply with the protocol specification.
1358 Old public keys are not supported anymore and are not compatible.
1360 * Removed nickname from Channel Payload as the latest draft removed
1361 it. The client must resolve the nickname from the NAMES command
1362 reply received when it joined the channel.
1364 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1366 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Fixed some errors in protocol specification drafts.
1370 * Created lib/silccore/silcnotify.c to implement Notify Payload
1371 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1372 generic payloads described by protocol specifications. The file
1373 includes implementations for ID Payload and Argument Payload.
1375 * Changed Command Payload implementation to use the new Argument
1376 Payload. Changed command_xxxx_payload to command_payload_xxxx
1377 to comply with SILC coding conventions.
1379 * Added suppport for Argument Payload handling in Notify Payload
1380 implementation as protocol requires it. Added the new support
1381 into server and client lib as well.
1383 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Added support for multiple nicknames on same channel. [n] is
1386 added locally to the nickname if there are more than one same
1387 nicknames on the channel.
1389 * Server now sends all nicknames that matched WHOIS request.
1390 Client also shows the list received from server.
1392 * Added TOPIC command to client side. User can now set and show
1393 current topic on channel.
1395 * Added MOTD command to client and server. Also, server sends the
1396 motd when client connects to the server.
1398 * Changed version strings to comply ISO 8601.
1400 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed protocol error handling in client library. It should now
1403 cope even if the SKE fails for some reason.
1405 * Made new protocol specification drafts for submitting to IETF.
1407 * Implemented TOPIC command to server in silcd/command.c.
1409 * Added two new notify types into lib/silccore/silcnotify.h:
1410 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1411 notify nickname change and topic setting/change on a channel.
1413 * API change of command_reply operation in client library. The
1414 application gets now the status type received from server as well.
1416 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1420 * Cras fixed and optimized the packet handling even further and
1421 it should work now. Minor change to the prototype of function
1422 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1424 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1426 * Added new function into lib/silcutil/silcschedule.[ch]:
1427 silc_schedule_with_fd to select() a specified fd. The function
1428 returns after timeout expires or data arrives or goes. The
1429 function is used by packet routines to wait that all data is
1430 received from network.
1432 * Fixed data reading from network in lib/silccore/silcpacket.c.
1433 The code now assures that all data is read from the fd and then
1434 continues packet processing. This was a bug fix since the code
1435 used to drop some data in some circumstances.
1437 * Added new function into lib/silcclient/client.[ch]:
1438 silc_client_start_key_exchange to start key exchange after
1439 connection has been established to server. The code internally
1440 now uses this funtion but its main purpose was to provide it
1441 for applications that perform their own connecting. After
1442 application has created a connection it merely calls this
1443 function to start the key exchange between client and server.
1444 The library takes care of everything else after that.
1446 Updated also lib/silcclient/README to explain the usage of
1449 * Do not send to application information that connection has
1450 been established. Application gets notified it by connect
1453 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Applied cras's patch to add silc_schedule_one function. The
1456 function runs scheduler once and returns.
1458 * Fixed the scheduler after cras messed it up. The timeout
1459 handling works now as it's supposed to work.
1461 * Added into lib/silccore/ silcnotify.h to include notify
1462 message types support. Changed silc_server_send_notify*
1463 functions, in server.[ch], to support those new notify types.
1464 Added the support for the notify types into client library,
1465 as well. Added new notify client operation into ops.h in
1468 * Changed silc_server_packet_send_to_channel to send normal
1469 packets instead of just channel message packets. The function
1470 is now used to send the notify packets to channels. It is not
1471 used to send channel message packets anymore, as server never
1474 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1475 va_arg()s as it seems to require it nowadays. I guess, if SILC
1476 is compiled with older va_arg() the new code should work anyway.
1478 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * Splitted core library. Core library (lib/silccore) includes
1481 now only SILC protocol specific core (and common) components.
1482 Created new utility library (lib/silcutil) that includes more
1483 generic purpose stuff. The stuff for util library was taken
1484 from the old core library. This was minor and easy split.
1486 * Created SILC Client Library (lib/silcclient) that includes
1487 implementation of the SILC client without user interface. This
1488 was major move from silc/ directory. The code has been changed
1489 so that it is transparent towards the user interface. The
1490 silc/ directory includes now the same user interface as before
1491 and it uses the new client library. Read lib/silcclient/README.
1492 Basicly, the client library performs everything else related
1493 to SILC except user interface handling. Also, configuration
1494 files are considered to be part of user interface and library
1495 does not handle them.
1497 This change also changed a lot of structures, function naming etc.
1498 Most important change was that SilcClientWindow object was
1499 renamed to SilcClientConnection in the client library. Created
1500 also new file lib/silcclient/ops.h. Also added new files
1501 silc/local_command.[ch] and silc/client_ops.[ch].
1503 All these changes were made to make it easier for user interface
1504 designers to create what ever user interface for the SILC client
1507 It is also expected that the server will be moved to lib
1508 directory as well and SILC Server Library will be created;
1509 sometimes in the future.
1511 * Removed Local commands from lib/silccore/silccommand.h as
1512 they are application specific and new client library does not
1513 handle any of those anymore.
1515 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1516 old client implementation in silc/.
1518 * Added support for callback functions in SILC_LOG_* macros.
1519 Application can now set its own callbacks that will be called
1520 instead of using the default functions that will always print
1521 the debug messages to stderr (or stdout). Also, debugging can
1522 now be disabled by setting silc_debug to FALSE and re-enabled by
1523 setting it to TRUE. Note, that logging will still work even
1524 if debugging is disabled.
1526 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1527 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1528 silc_log_reset_debug_callbacks.
1530 * To enable debugging in silc client one must give now -d
1531 option on command line.
1533 * Changed silc_schedule_init to automatically allocate task queues
1534 if they are not allocated before calling it.
1536 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Added GMP 3.1 into math library.
1540 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1543 a channel in SILC network. The packet is used by servers and
1544 routers to notify other routers that user has left a channel.
1545 This little feature was missing until now. Added the feature
1546 to protocol specification as well.
1548 Added functions: silc_server_send_remove_channel_user and
1549 silc_server_remove_channel_user into server.[ch].
1551 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1552 lib/silccore/silcpacket.h. However, they are not implemented
1555 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1557 * Fixed joining to a channel and sending channel messages
1558 between server and router. The channel message sending should
1559 now work inside a cell.
1561 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Fixed the private message sending between server and router.
1564 The private message sending should now work inside a cell.
1566 * Added silc_server_replace_id into server.[ch] to replace
1567 existing ID in the SILC network.
1569 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1570 and silc_idlist_replace_server_id into idlist.[ch] in server.
1572 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Fixed the server to server connections. Server can again now
1575 connect to router. Router to router connections probably does
1578 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added dynamic protocol registering support. Now protocols can
1581 registered and unregistered on the fly. Patch by cras.
1583 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1585 * Added lib/contrib directory to hold routines that some platforms
1586 don't have but are needed by SILC.
1588 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1589 into lin/contrib to provide getopt() and getopt_long() for
1590 those who don't have it.
1592 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Added AWAY command to client. When away message is set and
1595 client receives a private message packet the client automatically
1596 replies to the sender with the away message.
1598 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1599 bug seemed to be the cause of recent problems when compiling
1602 * Added version detection support to SKE protocol specification
1603 and added the new changes to the SKE implementation as well.
1604 There were other minor changes in the SKE protocol as well.
1606 Many changes in lib/silcske/silcske.[ch] and in
1607 lib/silcske/payload.[ch].
1609 * Added ^U functionality, clear input line. Patch from cras.
1611 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Mainly small bugfixes on core library. Fixed some debugging
1614 logging and buffer overflow in silclog.c.
1616 * Updated config.sub and config.guess on the distribution tree.
1618 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Added command lagging support in server. Client may execute
1621 commands now only once in two seconds.
1623 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Optimized packet reception. MAC computation and checking is now
1626 also more optimized. A lot previously duplicated code is now
1627 used as generic by both client and server.
1629 * Fixed key pair generation in clientutil.c
1631 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Added into lib/silccore/silcbufutil.[ch] new function;
1634 silc_buffer_realloc.
1636 * Moved generic packet sending/encryption functions to
1637 lib/silccore/silcpacket.[ch] from client and server. Some
1638 rewriting of the functions.
1640 * Moved all generic packet reception/decryption functions to
1641 lib/silccore/silcpacket.[ch] from client and server. The
1642 packet processing is now much cleaner in both client and server.
1643 These were major changes in both client and server.
1645 * Created many common functions in server to do packet sending.
1646 Previously code were duplicated a lot, this has been removed
1649 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Rewrote major parts of the ID cache system. Don't know
1652 whether it is better now or not but at least the API is more
1655 * Major rewrite on ID cache stuff on client because of the ID
1656 cache API changes. Added idlist.c to client.
1658 * Also major rewrite on ID cache stuff on server as well.
1659 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1660 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1661 in hand, instead they are all put into the ID cache system now.
1662 All server_idlist_* routines uses ID cache now instead of
1663 traversing its own lists (those lists does not exist anymore).
1664 SilcIDList though still exists. Also, SilcXXXEntry's are
1667 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Finally made the SKE implementation compliant to the protocol
1670 specification. All mp integers are now binary encoded as
1671 opposed being HEX encoded.
1673 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1676 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1677 functions: silc_[encode/decode]_pem. Also added function
1678 silc_encode_pem_file to PEM encode with newlines ('\n') for
1681 * SILC public keys are now encoded either PEM or binary. Same
1682 option is for private keys as well. By default private keys
1683 are binary encoded and public keys PEM encoded. Silly HEX
1684 encoding were removed.
1686 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1687 function to create fingerprints.
1689 * Fixed a bug in SHA1; does not change the original data anymore.
1691 * Partly implemented INFO command on client and server side.
1692 Fixed CLEAR command. Changes to SERVER command; show current
1693 server(s) when giving command without arguments. Added
1694 VERSION command to client.
1696 * Added check to server that unregistered connections cannot
1697 execute commands (unless it is specificly allowed).
1699 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Fixed screen refresh.
1703 * Fixed channel joining bug from client. On some circumstances
1704 client tried to join to a channel it had already joined.
1706 * Added public key verification process into client's protocol.c.
1707 The client now verifies the public key from user and saves
1708 it into ~./silc/serverkeys/ directory.
1710 Added into: clientutil.[ch]: silc_client_verify_server_key.
1712 * Changed SKE protocol's silc_ske_initiator_finish function
1713 to accept callback function that verifies the received public
1714 key. Removed old silc_ske_verify_public_key function.
1716 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1719 silc_pkcs_private_key[_data]_set.
1721 * Made the password and public authentication more cleaner in
1722 server's protocol.c.
1724 * Removed historic and obsolete protocol `channel_auth' from
1725 both client and server.
1727 * Removed wrong way of sending command status messages from
1728 server to client in server's command.c. The old way violated
1729 protocol specification.
1731 Changes to silccore/silccommand.[ch]: removed
1732 silc_command_encode_status_payload -> not needed anymore,
1733 changed silc_command_encode_payload_va to accept extra
1734 argument on variable argument list. The argument type must
1735 now be provided to the function. Also, added new function:
1736 silc_command_encode_reply_payload_va which is same as
1737 normal command_encode_payload_va except command status type
1738 is provided as extra argument.
1740 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added ~./silc directory handling. The directory includes the
1743 public and private keys for the client.
1745 Added silc_client_check_silc_dir, silc_client_create_identifier
1746 and silc_client_load_keys.
1748 * Implemented SILC protocol compliant public key. Added public
1749 and private key saving to and loading from files.
1751 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1752 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1753 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1754 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1755 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1757 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1758 silc_pkcs_load_[public/private]_key.
1760 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Added silc_server_get_route (route.[ch]) to get connection
1763 data for the fastest route for given ID.
1765 * Implemented INVITE command on client and server. The command
1766 were re-defined in the SILC Protocol Specification and the
1767 implementation now complies with the specification.
1769 * Implemented PING command on client and server.
1771 * Implemented NAMES command on client and server. The server side
1772 supports currently only normal server not router server yet.
1773 Some changes to NAMES definition in SILC protocol specification.
1775 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Implemented LEAVE command on client and server.
1779 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1780 again. This change was made to the protocol as well. Server
1781 should not violate the protocol specification anymore.
1783 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1786 was tested. SOCKS4 was not but should work anyway.
