1 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added support for quit message that client can "leave" on the
4 channel when it quits the SILC. It is ditributed inside the
5 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7 Added silc_server_free_client_data that will take the
8 signoff message as argument.
10 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
12 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
14 * Updated parts of the protocol specification to keep it up
17 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
20 payloads in one packet.
22 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
23 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
24 use now the new List flag.
26 * Also deprecated the following packet types: REPLACE_ID,
27 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
29 * Added list support for Notify packet in server.
31 * Added silc_server_send_notify_channel_change to send the
32 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
33 the silc_server_send_replace_id.
35 * Added silc_server_send_notify_nick_change to send the
36 NICK_CHANGE notify type. Deprecates the function
37 silc_server_send_replace_id.
39 * Added silc_server_send_notify_join to send the JOIN notify type.
40 Deprecates the function silc_server_send_new_channel_user.
42 * Added silc_server_send_notify_leave to send LEAVE notify type.
43 Deprecates the function silc_server_send_remove_channel_user.
45 * Added silc_server_send_notify_cmode and
46 silc_server_send_notify_cumode to send CMODE and CUMODE notify
47 types. Deprecates the silc_server_send_set_mode function.
49 * Added SERVER_SIGNOFF notify type to indicate that server has
50 quit. This means that all clients on the channel from that
51 server will drop. This can be also used when netsplit happens.
53 Deprecated REMOVE_ID packet type since it is not needed anymore
56 Added silc_server_send_notify_server_signoff to send the
57 SERVER_SIGNOFF notify type. Deprecates the function
58 silc_server_send_remove_id.
60 Added also silc_server_send_notify_signoff to send the
63 * Employed the PKCS #1. It is the mandatory way to do RSA in the
64 SILC protocol from this day on. Changed the protocol
65 specification as well.
67 * Added silc_server_send_notify_topic_set to send TOPIC_SET
68 notify type. It is used between routers to notify about
69 topic changes on a channel.
71 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
74 * Partly updated the protocol specification to comply with the
75 changes now made. It is still though a bit outdated.
77 * The JOIN notify type now takes one extra argument <Channel ID>.
78 The packet used to be destined to the channel but now the
79 JOIN type may be sent as list thus it is impossible to
80 destine it to any specific channel. By adding this argument
83 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Added CREDITS file. The CHANGES and CREDITS file will appear
86 in the distribution as well.
88 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
91 types in the server's silcd/packet_receive.c.
93 * Implemented CMODE and CUMODE to work in router environment.
95 * Fixed minor encoding and decoding buglet from the
96 lib/silccore/silcmode.c.
98 * Fixed buffer overflow from lib/silcclient/command.c in USERS
101 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
103 * Changed all SilcConfigServer* and silc_config_server* to
104 SilcServerConfig* and silc_server_config*, respectively.
107 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Associated the ID (client or server ID) to the Authentication
110 Payload to avoid any possibility of forging. Updated the
111 protocol specification and the code accordingly.
113 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * The RSA key length is now save to the RsaKey context in the
116 key generation process in lib/silccrypt/rsa.c. The key length
117 is now used to figure out the maximum size of the block allowed
118 to be encrypted/signed.
120 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
121 is equivalent to the silc_mp_mp2bin but does not allocate any
124 * Changed silc_mp_mp2bin API to take length argument. If it is
125 non-zero then the buffer is allocated that large. If zero, then
126 the size is approximated using silc_mp_sizeinbase, which however
129 * Created Global RNG API which is global RNG that application can
130 initialize. After initializing, any routine anywhere in the
131 code (including library) can use RNG without allocating a new
132 RNG object. This was done to allow this sort of use of the
133 RNG in code that has no chance to allocate RNG object. All
134 applications currently allocate this and many routines in the
135 library use this. Affected file lib/silccrypt/silcrng.[ch].
137 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
138 it to use the Global RNG API.
140 * Defined Authentication Payload into protocol specification that
141 is used during SILC session to authenticate entities. It is
142 used for example by client to authenticate itself to the server
143 to obtain server operator privileges.
145 Implemented this payload into the lib/silccore/silcauth.[ch].
146 Implemented also routines for public key based authentication
147 as the new protocol specification dictates.
149 Moved definitions of different authentication methods from
150 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
152 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
153 silc_pkcs_verify and silc_pkcs_sign_with_hash and
154 silc_pkcs_verify_with_hash functions into the file
155 lib/silccrypt/silcpkcs.[ch].
157 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * The client entry's userinfo pointer must be always valid.
160 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
161 will fail since it requires the userinfo. Now, the userinfo
162 is allocated as "" if actual userinfo does not exist. Actually,
163 it must exist and it is totally Ok to drop client connections
164 that does not announce the userinfo. However, we will make
165 this workaround for now.
167 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
168 to return the remote port by socket.
170 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
173 SILC_SERVER_PENDING_EXEC and added an new macro
174 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
175 data or when error occurs while processing the pending command.
177 Added new argument `destructor' into silc_server_command_pending
178 and to the SilcServerCommandPending object. This destructor is
179 now called after calling the pending callback or if error occurs
180 immediately. If error occurs the actual pending callback won't
181 be called at all - only the destructor. The destructor may be
182 NULL if destructor is not needed.
184 All this applies for client library code as well. Similar
185 changes were made there as well for the pending commands.
187 In the client, the application must now allocate the
188 SilcClientCommandContext with the silc_client_command_alloc
191 * Added reference counter to the SilcServerCommandContext. Added
192 function silc_server_command_alloc and silc_server_command_dup
195 Same type of functions added to the client library for the same
198 * Removed the cmd_ident from IDListData away since it is now
199 global for all connections. It is the command identifier used
200 in command sending and with pending commands. The affected file
203 * Added reference counter to the SilcSocketConnection objecet to
204 indicate the usage count of the object. The object won't be
205 freed untill the reference counter hits zero. Currently only
206 server uses this, and client ignores it. The client must be
207 set to use this too later. The affected files are
208 lib/silccore/silcsockconn.[ch]. Added also the function
209 silc_socket_dup to increase the reference counter.
211 This was mainly added because it is possible that the socket
212 is removed underneath of pending command or other async
213 operation. Now it won't be free'd and proper DISCONNECTING
214 flags, etc. can be set to avoid sending data to connection that
215 is not valid anymore.
217 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
218 the connection. After that it sets SILC_SET_DISCONNECTED.
219 It is, however, possible that the socket data is not still freed.
220 The silc_server_packet_process now checks that data is not
221 read or written to connection that is DISCONNECTED. The socket
222 get's freed when the reference counter hits zero.
224 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Changed the client operation API: channel_message operation's
227 `sender' is now the client entry of the sender, not the nickname
228 and the `channel' is the channel entry, not the channel name.
230 In the private_message operation the `sender' is now also the
231 client entry of the sender not the nickname.
233 Affected file is lib/silcclient/ops.h and all applications
234 using the client operations.
236 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Moved the calling of ops->connect() from connect_to_server_final
239 into receive_new_id functin since that is the point when the
240 client is actually allowed to send traffic to network. The
241 affected file is lib/silcclient/client.c.
243 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
246 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
247 (if needs broadcasting) instead of broadcasting the packets one
248 by one which would make a burst in the network traffic.
250 * Added `broadcast' argument to the functions in silcd/server.[ch]
251 silc_server_create_new_channel[_with_id] to indicate whether
252 to send New Channel packet to primary router.
254 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Added new function into the silcd/server.[ch] files:
257 silc_server_create_new_channel_with_id to create new channel with
258 already existing Channel ID.
260 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
261 lib/silccore/silcpacket.h. This packet is used t send list of
262 Set Mode payloads inside one packet. Server uses this to set
263 the modes for the channels and clients on those channels, that it
264 announced to the router when it connected to it. The protocol
265 specification has been updated accordingly.
267 * The silc_server_new_channel did not handle the packet coming
268 from normal server as it normally does not send that. However,
269 when it announces its channels it does send it. Implemented
270 the support for that.
272 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
273 into the file lib/silccore/id.h.
275 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Fixed memory leaks in the functions silc_idlist_del_client,
278 silc_idlist_del_channel and silc_idlist_del_server in the file
279 silcd/idlist.c. All of those leaked like a sieve.
281 * Fixed some small memory leaks in the client's function
282 silc_client_notify_by_server.
284 * Added functions into silcd/server.c: silc_server_announce_clients,
285 silc_server_announce_channels and silc_server_announce_server.
286 These functions are used by normal and router server to announce
287 to its primary router about clients, channels and servers (when
288 router) that we own. This is done after we've connected to the
291 These functions effectively implements the following packet types:
292 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
293 and SILC_PACKET_NEW_ID_LIST.
295 * Added new functions into the silcd/packet_receive.[ch]:
296 silc_server_new_id_list, silc_server_new_channel_list and
297 silc_server_new_channel_user_list to handle the incoming
298 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
300 * Added support of changing Channel ID in the function
301 silc_server_replace_id. If the server that announces a channel
302 to the router already exists in the router (with same name but
303 with different Channel ID), router is responsible to send
304 Replace ID packet to the server and force the server to change
305 the Channel ID to the one router has.
307 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
308 client that the Channel ID has been changed by the router. The
309 normal server sends this to the client. Client must start using
310 the new Channel ID as the channel's ID.
312 Implemented handling of this new type into lib/silcclient/client.c
313 into the function silc_client_notify_by_server.
315 * Added new function silc_idlist_replace_channel_id into the files
316 silcd/idlist.[ch] to replace the Channel ID.
318 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Call silc_server_command_identify_check always when processing
321 the IDENTIFY command in silcd/command.c
323 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
326 send keepalive packets. The packet can be sent by clients,
329 Added function silc_socket_set_heartbeat into the file
330 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
331 If not set, the heartbeat is not performed. The actual
332 heartbeat is implemented in the low level socket connection
333 library. However, application is responsible of actually
336 Added silc_server_send_heartbeat to send the actual heartbeat
337 packet into silcd/packet_send.[ch]. Server now performs
338 keepalive with all connections.
340 * Added silc_task_get_first function into lib/silcutil/silctask.c
341 to return the timeout task with shortest timeout. There was a bug
342 in task unregistration that caused problems. TODO has been
343 updated to include that task system must be rewritten.
345 * The client library will now resolve the client information when
346 receiving JOIN notify from server for client that we know but
347 have incomplete information.
349 * Rewrote parts of silc_server_remove_from_channels and
350 silc_server_remove_from_one_channel as they did not remove the
351 channel in some circumstances even though they should've.
353 * Encryption problem encountered in server:
355 The LEAVE command used to send the Channel Key packet to the
356 router immediately after generating it. However, the code
357 had earlier sent Remove Channel user packet but not immediately,
358 ie. it was put to queue. The order of packets in the router
359 was that Channel Key packet was first and Remove Channel User
360 packet was second, even though they were encrypted in the
361 reverse order. For this reason, MAC check failed. Now, this
362 is fixed by not sending the Channel Key packet immediately but
363 putting it to queue. However, this is more fundamental problem:
364 packets that are in queue should actually not be encrypted
365 because packets that are sent immediately gets encrypted
366 actually with wrong IV (and thus MAC check fails). So, packets
367 that are in queue should be encrypted when they are sent to
368 the wire and not when they put to the queue.
370 However, the problem is that the current system has not been
371 designed to work that way. Instead, the packet is encrypted
372 as soon as possible and left to the queue. The queue is then
373 just purged into wire. There won't be any fixes for this
374 any time soon. So, the current semantic for packet sending
377 o If you send packet to remote host and do not force the send
378 (the packet will be in queue) then all subsequent packets to the
379 same remote host must also be put to the queue. Only after the
380 queue has been purged is it safe again to force the packet
383 o If you send all packets immediately then it safe to send
384 any of subsequent packets through the queue, however, after
385 the first packet is put to queue then any subsequent packets
386 must also be put to the queue.
388 Follow these rules and everything works fine.
390 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Added new function silc_server_remove_clients_by_server to
393 remove all client entries from ID list when the server connection
394 is lost. In this case it is also important to invalidate all
395 client entires as they hold the invalid server entry. This
396 fixes fatal bug when server has lost connection and will reconnect
399 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
401 * Made some sanity checks to silc_server_daemonise like to check
402 whether the requested user and group actually exists.
404 * Added sanity check to SKE's silc_ske_responder_finish to check
405 that the public and private key actually is valid.
407 * Invalidate the client's nickname when receiving Replace ID
408 packet and the Client ID is being replaced. This means that the
409 server will query the nickname if someone needs it (client)
412 * Sort the ID Cache in client library when the ID Cache data
413 has changed (needs sorting).
415 * Do not allow for SILC client to create several connections to
416 several servers. The client does not support windows right now
417 and generating multiple connections causes weird behaviour.
419 Irssi-silc client does support windows and can handle several
420 connections without problems, see: www.irssi.org and SILC plugin.
422 * Fixed some places where client was added to the IDList. The
423 rule of thumb is following (in order to get everything right):
424 If the client is directly connected local client then the
425 `connection' argument must be set and `router' argument must be
426 NULL to silc_idlist_add_client function. If the client is not
427 directly connected client then the `router' argument must
428 bet set and the `connection' argument must be NULL to the
429 silc_idlist_add_client function.
431 * The funtion silc_server_packet_send_local_channel actually did
432 not check whether the client was locally connected or not. It
433 does that now. Fixed a bug related to LEAVE command.
435 * Fixed Remove Channel User payload parsing bug in server's
436 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
438 * The server's silc_server_save_channel_key now checks also the
439 global ID list for the channel as it might not be in the local
440 list. Fixed a bug related to LEAVE command.
442 * Is this the end of the [<unknown>] buglet that has been lurking
443 around for a long time? A little for loop fix in server's
444 silc_server_command_whois_parse that is used by both IDENTIFY
445 and WHOIS command. At least, this was a clear bug and a cause
446 of one type of [<unknown>] buglet.
448 * WHOIS and IDENTIFY commands call the function
449 silc_server_command_[whois/identify]_check function even if
450 we are not router server.
452 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Added --with-gmp configuration option. If set the GMP
455 is always compiled in the SILC source tree. If not set then
456 it is checked whether the system has the GMP3 installed. If
457 it has then the GMP won't be compiled (the system's headers
458 and library is used), if it doesn't have it then the GMP is
459 compiled in the SILC source tree.
461 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Changed RSA private exponent generation to what PKCS #1
464 suggests. We try to find the smallest possible d by doing
465 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
466 not security fix but optimization.
468 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
470 * Added new config entry [Identity] to fork the server and run
471 it as specific user and group. A patch from Bostik.
473 * Imported Dotconf configuration library into lib/dotconf.
474 This will be used to create the SILC configuration files later.
475 It will appear in the distsribution after this commit.
477 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * A big code auditing weekend happening. Auditing code for
480 obvious mistakes, bugs and errors. Also, removing any code
483 Removed files for being obsolete:
485 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
486 inline in the file lib/silcutil/silcbuffer.h)
488 o lib/silcutil/silcbufutil.c (the header has inline versions)
490 Changed code to fix possible error conditions:
492 o The buffer formatting routines now check that the destination
493 buffer really has enough space to add the data. This applies for
494 both buffer formatting and unformatting
495 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
496 unformatting was changed to accomodate following rules:
497 XXX_*STRING_ALLOC will allocate space for the data into the pointer
498 sent to the function while XXX_*STRING will not allocate or copy
499 the data into the buffer. Instead it sets the pointer from the
500 buffer into the pointer sent as argument (XXX_*STRING used to
501 require that the pointer must be allocated already). This change
502 makes this whole thing a bit more consistent and more optimized
503 (note that the data returned in the unformatting with XXX_*STRING
504 must not be freed now). The routines return now -1 on error.
506 o Tried to find all code that use buffer_format and buffer_unformat
507 and added return value checking to prevent formatting and
508 especially unformatting errors and possible subsequent fatal
511 o Changed ske->x and ske->KEY to mallocated pointers in
512 lib/silcske/silcske.h. Fixed possible data and memory leak.
514 o Added return value checking to all *_parse* functions. Fixed
515 many memory leaks as well.
517 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
518 so that buffer overflows would not happen. All code now also
519 checks the return value as it can fail.
521 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * Added reconnection support to server if the normal server looses
524 its connection to the router (for example if router is rebooted).
525 The server performs normal reconnection strategy implemented
526 to the server. Affected file silcd/server.c.
528 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Added new packet type SILC_PACKET_SET_MODE that is used to
531 distribute the information about changed modes (for clients,
532 channels and clients channel modes) to all routers in the
533 network. Updated the protocol specification accordingly.
535 Added functions into silcd/packet_send.c and
536 silcd/packet_receive.c: silc_server_send_set_mode,
537 silc_server_set_mode.
539 Added new files silcmode.[ch] into lib/silccore that implements
540 the encoding and decoding of Set Mode Payload. Added new type
541 SilcSetModePayload. Moved the definitions of different modes
542 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
544 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Oops, a little mistake in server's connection authentication
547 protocol. The protocol is not ended with FAILURE but with
548 SUCCESS if the authentication is Ok. :) Affected file is
551 * Implemented NICK_CHANGE notify handling in server in the file
552 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
553 the local clients on the channel. After the changing nickname
554 in router environment snhould work and the [<unknown>] nickname
555 should appear no more.
557 The silc_server_replace_id function that receives the Replace ID
558 payload now sends the NICK_CHANGE notify type also in the file
559 silcd/packet_receive.c
561 * Changed WHOIS and IDENTIFY command to support the maximum amount
562 of arguments defined in protocol specs (3328 arguments). This
563 fixed a bug that caused problems when there were more than three
566 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Added extra parameter, command identifier, to the
569 silc_client_send_command so that explicit command identifier
572 Changed that ID list routines uses specific command identifier
573 when sending WHOIS/IDENTIFY requests to the server so that they
574 can be identified when the reply comes back.
576 Affected files lib/silcclient/command.[ch],
577 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
579 * Added `sender' argument to silc_server_packet_send_to_channel
580 to indicaet the sender who originally sent the packet to us
581 that we are now re-sending. Ignored if NULL. Affected file
582 silcd/packet_send.[ch].
584 * Added some server statistics support in silcd/server_internal.h
585 SilcServerStatistics structure and around the server code. Also
586 send some nice statistics information when client is connecting
589 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Fixed channel ID decoding in server's JOIN command reply in
592 silcd/command_reply.c
594 * Fixed braodcasting of replace ID payload to not to send it if
595 we are standalone server in silcd/packet_receive.c.
597 * Fixed all channel message sending routines to not to send
598 packets to clients that has router set, since they are routed
599 separately in the same function earlier. Affects file
600 silcd/packet_send.c and all channel packet sending functions.
602 * In USERS reply, res_argv[i] are not allocated, the table
603 is allocated. Thus changed that free the table, not its
606 * In server's whois_check and identify_check if the client is
607 locally connected do not send any WHOIS commands - they are not
610 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Fixed some minor bugs in client when sending WHOIS command. The
613 arguments was in wrong order.
615 * Removed statis function add_to_channel from server in
616 silcd/command.c that was previously used with the joining but
619 * Tested USERS command in router environment successfully with two
620 routers, two servers and two clients.
622 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
624 * Reorganized the USERS command and command reply in client library
625 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
626 When the command is given by user we register a pending command
627 callback that will reprocess the command after the reply has been
628 received from the server. When reprocessing the packet we then
629 display the information. Thus, the USERS information is displayed
630 now in the command callback instead of in the command reply
631 callback. The processing of the command is same as previously
632 when server has sent the command reply in the JOINing process.
634 * Added to USERS command in silcd/command_reply.c to join the client,
635 we didn't use to know about, to the channel after we've created
636 a client entry for it. Also, for clienet we did know already still
637 check whether it is on the channel or not and add it if not.
639 * Removed silc_server_command_join_notify as the function and its
642 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Changed the client's pending command handling to the same as the
645 server's pending command handling. It is also now possible to
646 execute command reply functions from other command reply
647 function as the function callbacks for commands and command
648 replies are one and same. The pending commands are not static
649 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
650 in client connection context. Thus, pending commands are server
651 connection specific as it is convenient.
653 Changed the function silc_client_command_pending and
654 silc_client_command_pending_del and added new function
655 silc_client_command_pending_check. Removed the
656 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
659 * Added cmd_ident, current command identifier, to the client
660 connection context in lib/silcclient/client.h to keep track on
661 command identifiers used in command sending. Client's command reply
662 function handling now supports the mandatory command identifiers.
664 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
665 funtions in client to fully support pending command callbacks.
667 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
668 as one of the arguments to the application in the command reply
671 * NOTE: The FORWARDED flag is depracated. It used to be depracated
672 before first releasing SILC but came back. Now it is removed again
673 and should come back nomore. The FORWARDED flag was used only
674 by the JOINing procedure by forwarding the command packet to router.
675 Now, the JOINing procedure has been changed to more generic (due
676 to various router environment issues) and FORWARDED is not needed
677 anymore for anything. The protocol specification is yet to be
680 Now, removed silc_server_packet_forward from server and the flag
681 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
683 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
685 * Renamed NAMES command to USERS command. The NAMES was named that
686 due to historical reasons. Now it is renamed. Also, rewrote
687 parts of the USERS command. The nickname list is not sent anymore
688 by the server. Only Client ID and mode lists are sent in the USERS
689 command. Changed this also to the protocol specification.
691 The client now resolves the names and stuff after it receives
692 the USERS list from the server when joining to the channel.
694 * WHOIS and IDENTIFY commands has been changed to support multiple
695 Client ID's per command. One can now search for multiple users
696 in the network by sending only one WHOIS or IDENTIFY command.
697 Changed the code and the protocol specifications.
699 * Removed silc_server_command_identify_parse and changed that IDENTIFY
700 uses silc_server_command_whois_parse to parse the request. */
702 * If normal server, do not parse the WHOIS and IDENTIFY requests
703 before sending it to the router. Saves some time.
705 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Fixed JOIN command on client library. Wrong number of arguments
708 used to crash the client.
710 * Added silc_server_channel_has_global function to check whether
711 channel has global users or not.
713 * Added silc_server_channel_has_local function to check whether channel
714 has locally connected clients on the channel.
716 * The silc_server_remove_from_one_channel now checks whether the
717 channel has global users or not after given client was removed from
718 the channel. It also checks whether the channel has local clients
719 on the channel anymore. If it does not have then the channel entry
720 is removed as it is not needed anymore.
722 * The silc_server_notify now checks on JOIN notify whether the joining
723 client is one of locally connected or global. If it is global then
724 the channel has now global users on the channel and that is marked
725 to the channel entry. Also, it now saves the global client to
726 global list who is joining and JOINs it to the channel. This is
727 for normal server, that is.
729 Changed silc_server_send_notify_on_channel,
730 silc_server_packet_relay_to_channel and
731 silc_server_packet_send_to_channel check if we are normal server
732 and client has router set (ie. global client) do not send the
733 message to that client, as it is already routed to our router.
735 * Implemented LEAVE notify type handling in silc_server_notify
738 * Tested LEAVE command in router environment successfully. Tested
739 with two routers, two servers and two clients.
743 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
745 * Implemented SIGNOFF notify type handling in silc_server_notify
748 * silc_server_remove_id now removes the client entry from all channels
749 it has joined and thusly sends SIGNOFF notify type.
751 * Rewrote the NAMES list generation in server by removing two excess
752 loops. The lists are created now inside one loop.
754 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * silc_server_remove_channel_user checks now also global list
757 for channel and client.
759 * silc_server_new_channel_user checks now both local and global
760 list for channel and client. Fixed a bug in client id decoding.
761 Used to decode wrong buffer.
763 * silc_server_channel_message checks now both local and global
764 list for channel entry.
766 * Tested channel joining (hence JOIN) in router environment
767 successfully. Tested with two routers, two servers and two
770 * Tested channel message sending in router environment successfully.
772 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Added silc_server_save_channel_key into server.[ch] to save the
775 received channel key in Channel Key payload processing. It is
776 also used in JOIN command reply handling.
778 Equivalent function silc_client_save_channel_key added into
779 client.[ch] into client library.
781 * Changed JOIN command reply to send information whether the channel
782 was created or not (is existing already) and the channel key
783 payload. Changed protocol specs accordingly.
785 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
786 the request was sent by ID and not by nickname. Crashed on
789 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
792 now correctly save the received data.
794 * silc_server_free_sock_user_data now notifies routers in the
795 network about entities leaving the network.
797 At the same time implemented functions silc_server_remove_id
798 and silc_server_send_remove_id to receive and send REMOVE_ID
799 packets. The packet is used to notify routers in the network
800 about leaving entities. The ID removed will become invalid in
803 * Added function silc_idlist_del_server into server. Removes and
804 free's server entry from ID list.
806 * silc_server_private_message function now checks, if we are router,
807 that the destination ID really is valid ID, naturally.
809 * In router when NEW_ID packet is received (for new client) the
810 hash of the Client ID is saved in the ID Cache but the
811 client->nickname is set to NULL, instead of putting the hash
814 IDENTIFY command now also checks that client->nickname must be
815 valid. If it is not if will request the data from the server who
816 owns the client. Added new function
817 silc_server_command_identify_check.
819 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
820 to set the command to already allocated Command Payload.
822 * Tested private message sending in router environment with two
823 routers, two servers and two clients. Fixed minor bugs and now
826 * Fixed segfault from client's NAMES command. Used to crash if
829 * Forwarded packets must not be routed even if it is not destined
830 to the receiver. Changed server code comply with this.
832 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Added `require_reverse_mapping' boolean value to ServerParams
835 structure. If TRUE (not default) the server will require that
836 the connecting host has fully qualified domain name.
838 If the reverse mapping is not required and hostname could not be
839 found the IP address is used as hostname.
841 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Implemented version string checking to both client and server.
844 The check is incomplete currently due to the abnormal version
845 strings used in development version of SILC.
847 * Changed all command functions in server to use the new
850 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Changed char *data to unsigned char *data in ID Cache system to
853 support binary data as ID Cache data. Changed code to support
854 binary data in lib/silccore/idcache.c.
856 * Renamed silc_server_packet_relay_command_reply to
857 silc_server_command_reply as it is normal packet receiving
858 function. Rewrote the function to accept command replys for
859 servers and not only for clients.
861 * Mark remote router always as registered server if we are connecting
862 to it. Otherwise, commands sent by the router to us are ignored.
864 * All ID List find routines now returns the ID Cache Entry pointer
865 as well if requested.
867 * WHOIS command works now in router environment, tested with two
868 routers, two servers and two clients.
870 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
871 in router environment (as it is almost equivalent to WHOIS) but
872 hasn't been tested thoroughly. Added new functions:
874 silc_server_command_identify_parse
875 silc_server_command_identify_send_reply
876 silc_server_command_identify_from_client
877 silc_server_command_identify_from_server
879 * Disabled route cache adding because adding two different ID's with
880 same IP replaces the old cache entry thus giving wrong route.
881 The entry->router->connection is always the fastest route anyway
882 so route cache may not be needed. Of course, new routes maybe
883 established after receiving the ID when the entry->router->connection
884 might not be anymore the most optimal.
886 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Add route cache for received ID for fast routing.
890 * Added silc_server_packet_route to route received packet on router
891 that is not destined to us.
893 * Renamed silc_server_get_route to silc_server_route_get.
895 * Added id_string and id_string_len fields into SilcServer to
896 include encoded ServerID for fast comparing without excess
897 encoding of the ID's.
899 * Cleaned up WHOIS command on server side. Added following static
902 silc_server_command_whois_parse
903 silc_server_command_whois_check
904 silc_server_command_whois_send_reply
905 silc_server_command_whois_from_client
906 silc_server_command_whois_from_server
908 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
909 arguments in command replies. All command functions should be
910 updated to use this macro.
912 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Minor typo fixes on command reply handling on server.
916 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Added silc_server_command_add_to_channel internal routine to add
919 the client to the channel after router has created the channel and
920 sent command reply to the server.
922 * Added generic silc_server_send_command to send any command from
925 * Use static buffer with ID rendering instead of duplicating data.
927 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Fixed a channel user mode bug when joining to a channel server gave
930 everybody channel founder rights, oops.
932 * We mark ourselves as the router of the incoming server connection
933 if we are router ourselves. This way we can check in some packet
934 sending functions whether it is locally connected server. For
935 incoming router connections we put NULL.
937 * For router sending packets locally means now always sending the
938 packet cell wide; to local clients and local servers. For normal
939 server sending packet locally means sending it to only local
942 * Fixed the JOIN command to really work in router environment. If the
943 channel is created it is always created by the router. Router is
944 also responsible of making the initial joining to the channel,
945 sending JOIN notify to the sending server and distributing
946 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
947 does not exist server doesn't do anything else but forward the
948 command to the router which performs everything.
950 * Added silc_server_send_channel_key function to send the Channel Key
953 * Added silc_server_create_channel_key to create new channel key. The
954 channel key is now re-generated everytime someone joins or leaves
955 a channel, as protocol dictates. Note: channel->key_len is the
958 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Splitted server.[ch] finally. Created now packet_send.[ch] and
961 packet_receive.[ch] to separate packet sending and receiving
962 routines. The server.[ch] now includes everything else including
963 actual packet processing (writing and reading data) and other
966 Renamed silc_server_private_message_send_internal to
967 silc_server_send_private_message. The routine is still though
968 used only to relay private messages as server does not send
969 private messages itself.
971 Renamed silc_server_new_channel to silc_server_create_new_channel
972 and added new function sicl_server_new_channel that handles the
973 incoming New Channel packet. Added also new sending function
974 silc_server_send_new_channel to send New Channel Payload.
976 * Added new function silc_server_notify to process incoming notify
977 packet to the server/router. Server may then relay the notify
978 to clients if needed.
980 * Added new function silc_server_new_channel_user to process incoming
981 New Channel User packet. Router will redistribute the packet and
982 send JOIN notify to its local clients and locally connected servers
983 if needed. Normal server will send JOIN notify to its local client
984 on same channel when received this packet. Added also corresponding
985 sending function silc_server_send_new_channel_user to sent the
988 * Added boolean route argument to send_notif_to_channel and
989 packet_send_to_channel functions to attempt to route the packet
990 if it is TRUE and send only locally if it is FALSE.
992 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * silc_server_replace_id now broadcasts the received replace ID
995 packet if it is not broadcast packet already. The router must
996 broadcast to inform other routers about changed ID.
998 * Added backpointer to server's router into SilcServer context in
999 silcd/server_internal.h.
1001 * Fixed silc_server_packet_broadcast to send correct broadcast
1004 * The channel key is now distributed to the local client as soon
1005 as it is received from the router (in router environment) so that
1006 no other packet may be sent for the channel until client has
1009 * silc_server_remove_channel_user now broadcasts the received
1010 Remove Channel User packet if it is not broadcast packet already.
1011 The router must broadcast to inform other routers about removed
1014 * Added users field into SilcPacketContext that is a reference count
1015 of the context. One can increase the reference count by calling
1016 silc_packet_context_dup which is now changed to just increase the
1017 reference count instead of duplicating the data. The reference
1018 count is decresed by calling silc_packet_context_free that will
1019 free the data after the reference count hits zero.
1021 For now on the packet context and everything allocated into it
1022 (including the raw packet from network) must be freed by calling
1023 the new silc_packet_context_free function. Added also new function
1024 silc_packet_context_alloc that must be used now to allocate the
1025 context. This also means that if a routine is asynchronous from
1026 silc_[client/server]_packet_parse_type the packet context must
1027 be duplicated by calling silc_packet_context_dup. Otherwise it
1028 gets free'd after silc_[client/server]_packet_parse_type returns.
1029 Also, one must remember that if packet is duplicated then its
1030 reference count must be decresed by calling the free function as
1031 many times as it was duplicated.
1033 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1034 from both client and server.
1036 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Made joining to a channel working in router environment.
1040 * Cleaned up JOIN command on server side and create function
1041 silc_server_command_join_channel internal routine to make the
1044 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Changed silc_command_pending list to SilcDList. Also, added
1047 `ident' field to SilcServerCommandPending structure to identify
1048 the reply and to call correct callback.
1050 Added silc_server_command_pending_check function to replace the
1051 corresnponding macro. The silc_command_pending list is not
1054 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1055 to set identifier to previously allocated Command Payload. It
1056 is used to set identifier for command when resending Command
1059 * Added silc_command_payload_encode_payload to encode Command
1060 Payload buffer from SilcCommandPayload structure.
1062 * Added silc_argument_payload_encode_payload to encode Argument
1063 payload buffer from SilcArgumentPayload structure.
1065 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Changed WHOIS command to support router connection on server side.
1068 The whois request is always sent to router unless the server is
1069 standalone server. After server has received the reply from the
1070 router will it send the reply to the client.
1072 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1073 broadcast received broadcast packet. The function is used only
1074 by router. The broadcast packet is always sent to the router's
1077 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1078 render given ID to printable string, for log files for example.
1080 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1082 * Made basic router to router connections working. At least they
1083 can now connect to each other but nothing really works the way
1084 they are supposed - yet.
1086 * Added new initiator token to RouterConnection configuration
1087 file in silcd/serverconfig.[ch]. It is used to tell whether we
1088 are the initiator to the remote router or whether we'll expect
1089 the other end to connect.
1091 * Moved registering of listener task to silc_server_init, hence
1092 the server starts listenning as soon as it is run, even if it
1093 does not have connections to other routers. Let's see how well
1096 * Changed default connection retry timeouts for more suitable in
1099 * Removed cipher and such arguments from silc_idlist_add_client
1100 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1101 Added new function silc_idlist_add_data to add the keys and stuff
1104 * Added SilcIDListData structure and added it to SilcClientEntry
1105 and SilcServerEntry as their first field in the structure. This
1106 way we can explicitly cast the ID entries to the SilcIDListData
1107 structure and get common data for the entries. In past, we had
1108 to first check what type of connection it is and then cast it to
1109 correct ID entry type. Now, we can directly cast the opaque
1110 pointer to the SilcIDListData (no matter what ID entry it actually
1111 is) and get the data needed.
1113 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1116 in some circumstances even if threre were timeout tasks, though not
1117 IO tasks, but tasks anyway. Now fixed.
1119 * Defined SilcServerConnection structure to hold connection specific
1120 stuff about directly connected servers and routers. The definition
1121 is currently in silcd/server_internal.h. I thought about having
1122 a bit more important role fro this struct but for now it is used
1123 only when connecting to other server (or router actually).
1125 * Added connecting retry support in server when connecting to
1126 router(s). The retry feature implement exponential backoff
1127 algorithm. Also, added SilcServerParams structure to hold default
1128 parameters for server. For now, it include these retry settings
1129 and are hard coded. After server is moded to be as Silc Server
1130 Library this structure will be more important.
1132 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * Changed client librarys channel->clients table to SilcList and
1135 changed code accordingly.
1137 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Changed client's channel table to SilcList and changed code
1140 accordingly. Also changed SilcChannelClientEntry to include back-
1141 pointer to the channel so that client entry can use that structure
1142 as list as well and we have fast cross-reference to the channel.
1143 This change dramatically decreased the complexity of channel
1144 handling with client entry and vice versa (removed one extra
1145 loop when searching for channel entry from many functions).
1147 * Changed server->sim from table to SilcDList and changed code
1150 * NAMES command can now be used from user interface. It will show
1151 the user list on the channel, neatly.
1153 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1154 Code now saves realname of the user if it becomes available.
1156 * Renamed configure.in to configure.in.pre and made ./prepare
1157 script to automatically add correct version string to
1158 configure.in which it creates from configure.in.pre.
1160 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * NAMES command reply now shows users mode with the nickname when
1165 * Moved silc_client_ch[u]mode[_char] functions from
1166 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1167 place sucks, they are utility functions and should be in some
1170 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1172 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1175 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Added TRQ (efficient deque and list library) into lib/trq. This is
1180 a very good list library that is currently used in the SILC. Defined
1181 SilcList API over the library because I didn't like the API very
1182 much. See lib/trq/silclist.h for the API and examples of how to
1183 use the API. Fixed various places in the code to use the new
1184 SilcList API. The SilcList is meant for lists that has a structure
1185 already defined as a list. It is not suitable to add just some
1186 context to the list (in TRQ, the context is the list actually).
1188 So, I defined SilcDList that can be used for the purpose where
1189 predefined list structure does not exit. This can be used as
1190 such list. Now some context just can be added to the SilcDList.
1191 Currently this list is not used in the SILC just yet, though there
1192 are a lot places where this can replace dynamically allocated
1193 tables and I will fix these places, later, to use SilcDList.
1194 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1195 and use TRQ internally).
1197 Also fixed some annoying warning messages that the original TRQ
1198 code generated. Also minor changes to TRQ's Makefile.in.
1200 * Added support for querying by Client ID to both WHOIS and
1201 IDENTIFY commands into server, as required by the protocol.
1203 * Removed method function pointers from SilcBuffer structure. They
1204 weren't used to anything and just increased the context size for
1205 no good reason. This change also made silc_buffer_alloc and
1206 silc_buffer_free functions inline functions.
1208 * Disabled command flooding detection support until it's fixed so
1209 that it accepts commands in but does not execute them more than once
1212 * Added silc_net_localhost(), to return local hostname, into
1213 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1214 that must be initialized before calling silc_client_init.
1216 * Added new function: silc_server_send_notify_on_channels to send
1217 notify messages to all channels client has joined. It is assured
1218 that the message is sent only once per client.
1220 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1221 lib/silcutil/silcutil.[ch] as silc_format function. The new
1222 function is generic and is used by server as well, not only by
1223 the logging routines.
1225 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1226 the provided version string was not acceptable. Added new function:
1227 silc_ske_check_version into lib/silcske/silcske.h. The function
1228 must be implemented by the application (client or server) and it
1229 does not reside in the SKE library. The function checks the version
1230 string remote end sent.
1232 * Added back pointers (to opaque context and to SilcSocketConnection)
1233 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1235 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1236 duplicate packet context structure.
1238 * Changed `notify' client operation to send same arguments as client
1239 receives from server except for ID's. ID's are mapped to correct
1240 ID entry and that is returned. Also, if channel entry is not sent
1241 by server but the notify is for channel the channel entry is sent
1242 to application (otherwise application doesn't know that it is for
1243 channel (library gets it from packet's Destination ID)).
1245 * Added silc_client_remove_from_channels into client library to
1246 remove a client from all channels it has joined to. Used when
1247 received SIGNOFF notify from server. Added also new function
1248 silc_client_replace_from_channels to replace old ID entry with
1249 new ID entry on all channels. Used when received NICK_CHANGE
1252 * Fixed ID Cache list handling in silc_idlist_get_client in
1253 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1254 to get (or query) client by ID.
1256 * Updated TODO list.
1258 * Added connection authentication status message defined by the
1259 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1260 support for these into the code in client and server side.
1262 * Added generic function silc_client_send_command to send any command
1263 with variable argument list. Application should use this function
1264 to send commands if the command functions provided by the library
1265 does not suite for the application's user interface needs.
1267 * Added new `failure' client operation. Application is notified about
1268 received failure packet if client is executing a protocol. In this
1269 case the protocol's execution has failed.
1271 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1272 is required by the protocol.
1274 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1275 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1278 * Added status flag to SilcSKE object to indicate realtime status
1279 of the SKE protocol.
1281 * Application receives now exactly same command reply arguments as
1282 the library receives from server. However, if ID is received the
1283 corresponding ID entry is returned to the application (eg. Client
1284 ID is mapped to correct SilcClientEntry entry and that is returned).
1285 Changed command_reply client operation due to this change.
1287 * Changed all ID's in commands and in command replys as ID Payloads.
1288 Change affected both client and server side codes.
1290 All ID's sent in SILC network (with execption of ID's in SILC
1291 Packet header) are sent in ID Payload to support variable length
1294 * Server now notifies nick changes and notifies all clients on
1295 the channels about the new nickname (about the new Client ID,
1298 * Implemented CMODE command to change channel modes. Supports all
1299 channel modes defined by the protocol specs except ban and invite
1300 lists. (Also, private channel key mode is supported but support for
1301 setting private channel key in client is missing, thus, this mode
1302 has no effect on client side (except that server requires that the
1303 client uses private channel key and normal channel traffic does not
1306 Also, invite mode works per se, but INVITE command does not work
1307 yet correctly, so you can set channel as invite only channel but
1308 inviting clients to the channel does not work (it is yet to be
1309 thought what's the best way to do it).
1311 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1312 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1313 Implemented CUMODE command to change user's mode on the channel.
1314 Supports all modes defined by the protocol specs.
1316 * Added NAMES command reply to return users modes on the channel.
1318 * Removed unnecessary and slow ciphers from lib/silccrypt.
1320 * Set SO_KEEPALIVE option to connection sockets by default.
1322 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1324 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1325 redefined the Notify Payload into protocol specs.
1327 * Added silc_id_payload_parse_id to get ID directly from raw
1330 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1333 accept searching by Client ID as well.
1335 * Added support for LEAVE and SIGNOFF notify types in client library.
1337 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1338 to parse ID Payload from raw data.
1340 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added flags parameter into silc_ske_assemble_security_properties
1343 function in lib/silcske/silcske.[ch].
1345 * Changed notify client operation to fit better for notify messages
1346 sent by server. The notify payload received from server is now
1347 passed to the application (after parsing it to SilcNotifyPayload).
1348 It is application's responsibility to retrieve the arguments
1349 from the payload and show the message the way it wants. The message
1350 sent by server is implementation specific.
1352 * Changed public keys to comply with the protocol specification.
1353 Old public keys are not supported anymore and are not compatible.
1355 * Removed nickname from Channel Payload as the latest draft removed
1356 it. The client must resolve the nickname from the NAMES command
1357 reply received when it joined the channel.
1359 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1361 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Fixed some errors in protocol specification drafts.
1365 * Created lib/silccore/silcnotify.c to implement Notify Payload
1366 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1367 generic payloads described by protocol specifications. The file
1368 includes implementations for ID Payload and Argument Payload.
1370 * Changed Command Payload implementation to use the new Argument
1371 Payload. Changed command_xxxx_payload to command_payload_xxxx
1372 to comply with SILC coding conventions.
1374 * Added suppport for Argument Payload handling in Notify Payload
1375 implementation as protocol requires it. Added the new support
1376 into server and client lib as well.
1378 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Added support for multiple nicknames on same channel. [n] is
1381 added locally to the nickname if there are more than one same
1382 nicknames on the channel.
1384 * Server now sends all nicknames that matched WHOIS request.
1385 Client also shows the list received from server.
1387 * Added TOPIC command to client side. User can now set and show
1388 current topic on channel.
1390 * Added MOTD command to client and server. Also, server sends the
1391 motd when client connects to the server.
1393 * Changed version strings to comply ISO 8601.
1395 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Fixed protocol error handling in client library. It should now
1398 cope even if the SKE fails for some reason.
1400 * Made new protocol specification drafts for submitting to IETF.
1402 * Implemented TOPIC command to server in silcd/command.c.
1404 * Added two new notify types into lib/silccore/silcnotify.h:
1405 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1406 notify nickname change and topic setting/change on a channel.
1408 * API change of command_reply operation in client library. The
1409 application gets now the status type received from server as well.
1411 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1415 * Cras fixed and optimized the packet handling even further and
1416 it should work now. Minor change to the prototype of function
1417 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1419 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Added new function into lib/silcutil/silcschedule.[ch]:
1422 silc_schedule_with_fd to select() a specified fd. The function
1423 returns after timeout expires or data arrives or goes. The
1424 function is used by packet routines to wait that all data is
1425 received from network.
1427 * Fixed data reading from network in lib/silccore/silcpacket.c.
1428 The code now assures that all data is read from the fd and then
1429 continues packet processing. This was a bug fix since the code
1430 used to drop some data in some circumstances.
1432 * Added new function into lib/silcclient/client.[ch]:
1433 silc_client_start_key_exchange to start key exchange after
1434 connection has been established to server. The code internally
1435 now uses this funtion but its main purpose was to provide it
1436 for applications that perform their own connecting. After
1437 application has created a connection it merely calls this
1438 function to start the key exchange between client and server.
1439 The library takes care of everything else after that.
1441 Updated also lib/silcclient/README to explain the usage of
1444 * Do not send to application information that connection has
1445 been established. Application gets notified it by connect
1448 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Applied cras's patch to add silc_schedule_one function. The
1451 function runs scheduler once and returns.
1453 * Fixed the scheduler after cras messed it up. The timeout
1454 handling works now as it's supposed to work.
1456 * Added into lib/silccore/ silcnotify.h to include notify
1457 message types support. Changed silc_server_send_notify*
1458 functions, in server.[ch], to support those new notify types.
1459 Added the support for the notify types into client library,
1460 as well. Added new notify client operation into ops.h in
1463 * Changed silc_server_packet_send_to_channel to send normal
1464 packets instead of just channel message packets. The function
1465 is now used to send the notify packets to channels. It is not
1466 used to send channel message packets anymore, as server never
1469 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1470 va_arg()s as it seems to require it nowadays. I guess, if SILC
1471 is compiled with older va_arg() the new code should work anyway.
1473 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Splitted core library. Core library (lib/silccore) includes
1476 now only SILC protocol specific core (and common) components.
1477 Created new utility library (lib/silcutil) that includes more
1478 generic purpose stuff. The stuff for util library was taken
1479 from the old core library. This was minor and easy split.
1481 * Created SILC Client Library (lib/silcclient) that includes
1482 implementation of the SILC client without user interface. This
1483 was major move from silc/ directory. The code has been changed
1484 so that it is transparent towards the user interface. The
1485 silc/ directory includes now the same user interface as before
1486 and it uses the new client library. Read lib/silcclient/README.
1487 Basicly, the client library performs everything else related
1488 to SILC except user interface handling. Also, configuration
1489 files are considered to be part of user interface and library
1490 does not handle them.
1492 This change also changed a lot of structures, function naming etc.
1493 Most important change was that SilcClientWindow object was
1494 renamed to SilcClientConnection in the client library. Created
1495 also new file lib/silcclient/ops.h. Also added new files
1496 silc/local_command.[ch] and silc/client_ops.[ch].
1498 All these changes were made to make it easier for user interface
1499 designers to create what ever user interface for the SILC client
1502 It is also expected that the server will be moved to lib
1503 directory as well and SILC Server Library will be created;
1504 sometimes in the future.
1506 * Removed Local commands from lib/silccore/silccommand.h as
1507 they are application specific and new client library does not
1508 handle any of those anymore.
1510 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1511 old client implementation in silc/.
1513 * Added support for callback functions in SILC_LOG_* macros.
1514 Application can now set its own callbacks that will be called
1515 instead of using the default functions that will always print
1516 the debug messages to stderr (or stdout). Also, debugging can
1517 now be disabled by setting silc_debug to FALSE and re-enabled by
1518 setting it to TRUE. Note, that logging will still work even
1519 if debugging is disabled.
1521 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1522 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1523 silc_log_reset_debug_callbacks.
1525 * To enable debugging in silc client one must give now -d
1526 option on command line.
1528 * Changed silc_schedule_init to automatically allocate task queues
1529 if they are not allocated before calling it.
1531 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Added GMP 3.1 into math library.
1535 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1538 a channel in SILC network. The packet is used by servers and
1539 routers to notify other routers that user has left a channel.
1540 This little feature was missing until now. Added the feature
1541 to protocol specification as well.
1543 Added functions: silc_server_send_remove_channel_user and
1544 silc_server_remove_channel_user into server.[ch].
1546 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1547 lib/silccore/silcpacket.h. However, they are not implemented
1550 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Fixed joining to a channel and sending channel messages
1553 between server and router. The channel message sending should
1554 now work inside a cell.
1556 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Fixed the private message sending between server and router.
1559 The private message sending should now work inside a cell.
1561 * Added silc_server_replace_id into server.[ch] to replace
1562 existing ID in the SILC network.
1564 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1565 and silc_idlist_replace_server_id into idlist.[ch] in server.
1567 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Fixed the server to server connections. Server can again now
1570 connect to router. Router to router connections probably does
1573 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1575 * Added dynamic protocol registering support. Now protocols can
1576 registered and unregistered on the fly. Patch by cras.
1578 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added lib/contrib directory to hold routines that some platforms
1581 don't have but are needed by SILC.
1583 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1584 into lin/contrib to provide getopt() and getopt_long() for
1585 those who don't have it.
1587 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Added AWAY command to client. When away message is set and
1590 client receives a private message packet the client automatically
1591 replies to the sender with the away message.
1593 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1594 bug seemed to be the cause of recent problems when compiling
1597 * Added version detection support to SKE protocol specification
1598 and added the new changes to the SKE implementation as well.
1599 There were other minor changes in the SKE protocol as well.
1601 Many changes in lib/silcske/silcske.[ch] and in
1602 lib/silcske/payload.[ch].
1604 * Added ^U functionality, clear input line. Patch from cras.
1606 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Mainly small bugfixes on core library. Fixed some debugging
1609 logging and buffer overflow in silclog.c.
1611 * Updated config.sub and config.guess on the distribution tree.
1613 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Added command lagging support in server. Client may execute
1616 commands now only once in two seconds.
1618 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Optimized packet reception. MAC computation and checking is now
1621 also more optimized. A lot previously duplicated code is now
1622 used as generic by both client and server.
1624 * Fixed key pair generation in clientutil.c
1626 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added into lib/silccore/silcbufutil.[ch] new function;
1629 silc_buffer_realloc.
1631 * Moved generic packet sending/encryption functions to
1632 lib/silccore/silcpacket.[ch] from client and server. Some
1633 rewriting of the functions.
1635 * Moved all generic packet reception/decryption functions to
1636 lib/silccore/silcpacket.[ch] from client and server. The
1637 packet processing is now much cleaner in both client and server.
1638 These were major changes in both client and server.
1640 * Created many common functions in server to do packet sending.
1641 Previously code were duplicated a lot, this has been removed
1644 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Rewrote major parts of the ID cache system. Don't know
1647 whether it is better now or not but at least the API is more
1650 * Major rewrite on ID cache stuff on client because of the ID
1651 cache API changes. Added idlist.c to client.
1653 * Also major rewrite on ID cache stuff on server as well.
1654 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1655 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1656 in hand, instead they are all put into the ID cache system now.
1657 All server_idlist_* routines uses ID cache now instead of
1658 traversing its own lists (those lists does not exist anymore).
1659 SilcIDList though still exists. Also, SilcXXXEntry's are
1662 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Finally made the SKE implementation compliant to the protocol
1665 specification. All mp integers are now binary encoded as
1666 opposed being HEX encoded.
1668 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1671 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1672 functions: silc_[encode/decode]_pem. Also added function
1673 silc_encode_pem_file to PEM encode with newlines ('\n') for
1676 * SILC public keys are now encoded either PEM or binary. Same
1677 option is for private keys as well. By default private keys
1678 are binary encoded and public keys PEM encoded. Silly HEX
1679 encoding were removed.
1681 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1682 function to create fingerprints.
1684 * Fixed a bug in SHA1; does not change the original data anymore.
1686 * Partly implemented INFO command on client and server side.
1687 Fixed CLEAR command. Changes to SERVER command; show current
1688 server(s) when giving command without arguments. Added
1689 VERSION command to client.
1691 * Added check to server that unregistered connections cannot
1692 execute commands (unless it is specificly allowed).
1694 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Fixed screen refresh.
1698 * Fixed channel joining bug from client. On some circumstances
1699 client tried to join to a channel it had already joined.
1701 * Added public key verification process into client's protocol.c.
1702 The client now verifies the public key from user and saves
1703 it into ~./silc/serverkeys/ directory.
1705 Added into: clientutil.[ch]: silc_client_verify_server_key.
1707 * Changed SKE protocol's silc_ske_initiator_finish function
1708 to accept callback function that verifies the received public
1709 key. Removed old silc_ske_verify_public_key function.
1711 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1714 silc_pkcs_private_key[_data]_set.
1716 * Made the password and public authentication more cleaner in
1717 server's protocol.c.
1719 * Removed historic and obsolete protocol `channel_auth' from
1720 both client and server.
1722 * Removed wrong way of sending command status messages from
1723 server to client in server's command.c. The old way violated
1724 protocol specification.
1726 Changes to silccore/silccommand.[ch]: removed
1727 silc_command_encode_status_payload -> not needed anymore,
1728 changed silc_command_encode_payload_va to accept extra
1729 argument on variable argument list. The argument type must
1730 now be provided to the function. Also, added new function:
1731 silc_command_encode_reply_payload_va which is same as
1732 normal command_encode_payload_va except command status type
1733 is provided as extra argument.
1735 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Added ~./silc directory handling. The directory includes the
1738 public and private keys for the client.
1740 Added silc_client_check_silc_dir, silc_client_create_identifier
1741 and silc_client_load_keys.
1743 * Implemented SILC protocol compliant public key. Added public
1744 and private key saving to and loading from files.
1746 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1747 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1748 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1749 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1750 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1752 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1753 silc_pkcs_load_[public/private]_key.
1755 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Added silc_server_get_route (route.[ch]) to get connection
1758 data for the fastest route for given ID.
1760 * Implemented INVITE command on client and server. The command
1761 were re-defined in the SILC Protocol Specification and the
1762 implementation now complies with the specification.
1764 * Implemented PING command on client and server.
1766 * Implemented NAMES command on client and server. The server side
1767 supports currently only normal server not router server yet.
1768 Some changes to NAMES definition in SILC protocol specification.
1770 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Implemented LEAVE command on client and server.
1774 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1775 again. This change was made to the protocol as well. Server
1776 should not violate the protocol specification anymore.
1778 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1781 was tested. SOCKS4 was not but should work anyway.
